Description:DESCRIPTION
Technical Field
[001] This disclosure relates generally to vehicles having cabin section and cargo section, and more particular to a system for adjusting cargo space of the vehicle, by moving a rear wall separating the cabin section and the cargo section.

BACKGROUND
[002] Pickup trucks are used for variety of purposes including transportation of agricultural products, fast-moving consumer goods (FMCG) products, e-commerce, and personal use. Pickup trucks are available in multiple different configurations. For example, crew-cab configuration pickup trucks are used as lifestyle vehicle for personal use with compromised cargo space. Single-cab configuration pickup trucks are used for goods transportation with compromised cabin space.
[003] As such, in these pickup trucks, the cabin space and cargo space is fixed. However, the fixed cabin and cargo space limits the multipurpose usage of these vehicle for catering to the customer requirement.
[004] There is, therefore, a need for an adjustable mechanism for changing (i.e. increasing or decreasing) cabin and cargo space of the pickup vehicle as per customer requirement.

SUMMARY OF THE INVENTION
[005] In an embodiment, a vehicle is disclosed. The vehicle may include a cabin section positioned towards the front of the vehicle. The cabin section may define a cabin space and may include at least one seating row positioned within the cabin space. The vehicle may further include a floor and a cargo section positioned towards the rear of the vehicle and behind the cabin section. The cargo section may define a cargo space. The cargo section may include a loadbody which may include a floor panel towards a bottom of the vehicle, a rear panel towards the rear of the vehicle, and a front panel towards the front of the vehicle and adjacent to the rear panel. The vehicle may further include a rear wall positioned between and separating the cabin section and the cargo section. The rear wall may be longitudinally moveable relative to the floor of the cabin section, to increase or decrease the cabin space and correspondingly decrease or increase, respectively, the cargo space. Further, the front panel may be rotatable relative to the floor panel about a front edge of the floor panel, to decrease or increase the cargo space.

DETAILED DESCRIPTION OF THE DRAWINGS
[020] Exemplary embodiments are described with reference to the accompanying drawings. Wherever convenient, the same reference numbers are used throughout the drawings to refer to the same or like parts. While examples and features of disclosed principles are described herein, modifications, adaptations, and other implementations are possible without departing from the spirit and scope of the disclosed embodiments. It is intended that the following detailed description be considered as exemplary only, with the true scope and spirit being indicated by the following claims. Additional illustrative embodiments are listed below.
[021] Referring now to FIG. 1, a schematic drawing of a side view of a vehicle 100 is illustrated, in accordance with some embodiments of the present disclosure. The vehicle 100 may be a pick-up truck, for example, a pick-up truck having a quad cab configuration or a crew cab configuration. As will be appreciated by those skilled in the art, the quad cab configuration has a lesser leg room as compared to that of the crew cab configuration. Further, the quad cab configuration has a longer bed (i.e. cargo space towards the rear end) in comparison with the crew cab configuration. The present disclosure provides for a solution that allows the crew cab configuration vehicle to be used as a single cab with larger cargo space as well as a double cab with adequate cabin space by adjusting cabin rear wall.
[022] The vehicle 100 may include a cabin section 102 positioned towards the front of the vehicle 100. The cabin section 102 may define a cabin space and may include at least one seating row positioned within the cabin space. For example, the cabin section 102 may include two seating rows - a front seating row 104A and a rear seating row 104B positioned behind the front seating row 104A. The vehicle 100 may further include a floor 106. Further, the vehicle 100 may include a cargo section 108 positioned towards the rear of the vehicle 100 and behind the cabin section 102. The cargo section may define a cargo space. The vehicle 100 may further include a rear wall 110 positioned between and separating the cabin section 102 and the cargo section 108. It should be noted that the rear wall 110 may be longitudinally moveable relative to the floor 106 of the cabin section 102, to increase or decrease the cabin space and correspondingly decrease or increase, respectively, the cargo space.
[023] As shown in FIG. 1, the rear wall 110 is positioned away from the cabin section 102, to thereby create extra cabin space within the cabin section 102. Due to this positioning of the rear wall 110, a reduced cargo space is created in the cargo section. The cargo section 108 may include a loadbody 114. The loadbody 114 may include a floor panel 116 which may form fixed section of the loadbody 114. The loadbody 114 may further include a front panel 112, which may be configurable between a horizontal position and a vertical position. As shown in FIG. 1, the front panel 112 is configured in the vertical position. As such, with the front panel 112 configured in the vertical position, an effective length of the floor of the cargo section 108 may be the length of the floor panel 116. Therefore, in order to move the rear wall 110, the front panel 112 may be is rotated about the pivot, as per required orientation, to utilize the cargo space for different applications. The front panel 112 can provide extended space for cargo usage and can also be used for multiple lifestyle applications (such as for customer lounge).
[024] The floor panel 116 may be positioned towards the bottom of the vehicle 100. The front panel 112 may be positioned towards the front of the vehicle 100. The front panel 112 may be rotatable relative to the floor panel 116 about a front edge of the floor panel 116. Further, the front panel 112 may be configurable between a horizontal position and a vertical position. The loadbody 114 may further include a rear panel 128 positioned towards the rear of the vehicle. The rear panel 128 may be configured in a vertical orientation, as shown in FIG. 1, to create a define a rear periphery of the loadbody 114. The loadbody 114 may further include a left-side panel and a right-side panel (not shown in FIG. 1) that define a left and right periphery of the loadbody 114. The rear panel 128, the left-side panel, and the right-side panel prevent the cargo from falling off the loadbody 114.
[025] As shown in FIG. 1 the front panel 112 is configured in the vertical position. In the vertical position, the front panel 112 may be aligned vertically and substantially perpendicular to the floor panel 116, to create a shortened loadbody 114 of the cargo section 108. As will be understood, when the rear wall 110 is positioned away from the cabin section 102 to create increase cabin space and decreased cargo space, the front panel 112 has to be rotated and oriented in the vertical position, to thereby accommodate the rear wall 110.
[026] Referring now to FIG. 2, a schematic drawing of the side view of the vehicle 100 with the rear wall 110 positioned towards the cabin section 102 is illustrated, in accordance with some embodiments. Therefore, as shown in FIG. 2, the rear wall 110 is longitudinally moved relative to the floor 106 towards the cabin section 102, to increase the cabin space. Due to this positioning of the rear wall 110, the cargo space is increased. Further, this also allows the front panel 112 to be configured in the horizontal position. As can be seen in FIG. 2, in the horizontal position, the front panel 112 is aligned horizontally and parallel to the floor panel 116, to create a continuous extended loadbody 114. As such, with the front panel 112 configured in the horizontal position, an effective length of the floor of the cargo section 108 may be the combination of the length of the floor panel 116 and the length of the front panel 112.
[027] In order for the rear wall 110 to be longitudinally moveable relative to the floor 106 of the cabin section 102, the vehicle 100 may further include a bottom slider assembly 120. The bottom slider assembly 120, for example, may be fitted to the floor 106 of the cabin section 102. The rear wall 110 may engage with the bottom slider assembly 120. The bottom slider assembly 120 may enable the rear wall 110 to be longitudinally moveable relative to the floor 106 of the cabin section 102. In other words, the rear wall 110 may be longitudinally moveable relative to the floor 106 of the cabin section 102 via the bottom slider assembly 120.
[028] By way of an example, as shown in FIGs. 1-2, the bottom slider assembly 120 may include at least one rack-and-pinion assembly. For example, the bottom slider assembly 120 may include two rack-and-pinion assemblies 120 (the terms ‘bottom slider assembly’ and ‘rack-and-pinion assembly’ may have been used interchangeable in this disclosure) – one rack-and-pinion assembly 120 positioned towards the left side of the vehicle and the other rack-and-pinion assembly 120 positioned towards the right side of the vehicle and the other. In other example embodiments, bottom slider assembly 120 including a single rack-and-pinion assembly 120 or more than two rack-and-pinion assemblies 120 may be possible as well. In some embodiments, the rack-and-pinion assembly 120 may be motor driven. In alternate embodiments, the rack-and-pinion assembly 120 may be manually operated. Further, in some embodiments, the rack-and-pinion assembly 120 may be provided inside or outside sill part 124 of the vehicle 100. As such, the rear wall 110 may be adjusted, as per the requirement, by toppling the rear seating row 104B, and then translating the rear wall 110 through the rack-and-pinion assembly 120 and the top slider assembly 122.
[029] One of a rack and a pinion of the at least one rack-and-pinion assembly may be fitted to the floor of the cabin section and the other of the rack and the pinion of the at least one rack-and-pinion assembly is fitted to the rear wall. FIG. 3 shows a magnified view of the bottom slider assembly 120, in accordance with some embodiments. As can be seen in FIG. 3, the bottom slider assembly 120 may be configured as a rack-and-pinion assembly that includes a rack 304 and a pinion 302. The pinion 302 is fitted to the floor 106 of the cabin section 102 and the rack 304 is fitted to the rear wall 110. The pinion 302 may, therefore, enable the rack 304 to translate longitudinally, to thereby enable the longitudinal movement of the rear wall 110. In alternate embodiments, the pinion 302 may be fitted to the rear wall 110 and the rack 304 may be fitted to the floor of the cabin section 102.
[030] Referring once again to FIGs. 1-2, the cabin section 102 may further include a roof 118. In some embodiments, the rear wall 110 may be engaged with and longitudinally moveable relative to the roof 118 of the cabin section 102.
[031] In order for the rear wall 110 to be longitudinally moveable relative to the roof 118 of the cabin section 102, the vehicle 100 may further include a top slider assembly 122 which may be fitted to the roof 118 of the cabin section 102. The rear wall 110 may be longitudinally moveable relative to the roof 118 of the cabin section 102 via the top slider assembly 122.
[032] In some embodiments, the top slider assembly 122 may include a at least one guide fitted to the roof 118 of the cabin section 102 and a guide pin fitted to the rear wall 110. FIG. 4 illustrates a magnified view of the top slider assembly 122, in accordance with some embodiments. As shown in FIG. 4, the top slider assembly 122 include a guide 402 fitted to the roof 118 of the cabin section 102 and a guide pin 404 fitted to a top end of the rear wall 110. The guide pin 404 may be configured to engage with the guide 402. The guide 402 may be configured as a slotted rail such that the guide pin 404 is slidably coupled with the slotted rail and is enabled to translate longitudinally along the length of the slotted rail, to thereby guide the rear wall 110 to move longitudinally relative to the roof 118 of the cabin section 102. Further, in different embodiments, the top slider assembly 122 may include a single guide 402, or two guides 402, or two or more guides 402. For example, the top slider assembly 122 may be attached to a B-pillar 126 of the vehicle. It should be noted that the top slider assembly 122 may not be limited to the above embodiment of the guide and the guide pin, however, may include any other mechanism for guided travel of the rear wall 110 relative to the roof 118.
[033] Therefore, a system for adjusting the cargo space of the vehicle 100 is provided. The system may include the rear wall 110 positioned between and separating the cabin section 102 and the cargo section 108, such that the cabin section 102 may be positioned towards the front of the vehicle 100 and defining the cabin space. The cargo section 108 may be positioned towards the rear of the vehicle 100 and behind the cabin section 102 and defining the cargo space. The cabin section 102 includes the at least one seating row 104A, 104B positioned within the cabin space, the floor 106, and the roof 118. The system further includes the bottom slider 120 assembly fitted to the floor 106 of the cabin section 102, such that the rear wall 110 may be longitudinally moveable relative to the floor 106, via the bottom slider assembly 120, to increase or decrease the cabin space and correspondingly decrease or increase, respectively, the cargo space. Additionally or alternatively, the system may further include top slider assembly 122 fitted to the roof 118 of the cabin section 102, such that the rear wall 110 is engaged with and is longitudinally moveable relative to the roof 118, via the top slider assembly 122.
[034] Referring now to FIGs. 5A-5B, magnified views of the rear seating row 104B in different scenarios are illustrated, in accordance with some embodiments. As mentioned above, the cabin section 102 may include the rear seating row 104B positioned behind the front seating row 104A. In some embodiments, the rear seating row 104B may be adaptable with the varying cabin space due the longitudinal movement of the rear wall 110. To this end, the rear seating row 104B may include a back rest 502 which may be fitted to the rear wall 110. The rear seating row 104B may further include a bottom rest 504 which may be pivoted to the rear wall 110 and therefore rotatable relative to the back rest 502. The bottom rest 504 may be configurable between an extended position and a collapsed position.
[035] FIG. 5A illustrates a first scenario in which the bottom rest 504 is configurable in the extended position. In the extended position, the bottom rest 504 may be substantially parallel to the floor 106 of the cabin section 102. In other words, in the extended position, the bottom rest 504 may be configured in a seating position to allow a passenger to sit over it. Therefore, in the extended position, the bottom rest 504 may be oriented substantially parallel to the floor 106 and substantially perpendicular to the back rest 502. As such, in this scenario, to accommodate the bottom rest 504 in the extended position, the rear wall 110 may be positioned away from the cabin section 102, to increase the cabin space.
[036] Additionally, the bottom rest 504 may include one or more support legs 506 provide underneath the bottom rest 504. The one or more support legs may provide support to the bottom rest 504, when the bottom rest 504 configured in the extended position. In particular, the one or more support legs may allow the load on the bottom rest 504 to be transferred to the floor 106 of the cabin section 102.
[037] FIG. 5B illustrates a second scenario in which the bottom rest 504 is configurable in the collapsed position. In the collapsed position, the bottom rest 504 may be substantially perpendicular to the floor 106 of the cabin section 102. In other words, in the collapsed position, the bottom rest 504 may be configured in a folded position. Therefore, in the collapsed position, the bottom rest 504 may be oriented substantially perpendicular to the floor 106 and substantially parallel to the back rest 502. As will be understood, the bottom rest 504 may be configured in the collapsed position, to allow the rear wall 110 to be positioned closer to the cabin section 102, to thereby decrease the cabin space and increase the cargo space.
[038] Referring now to FIGs. 6A-6F, side views and rear views of the cargo section 108 in different scenarios are illustrated, in accordance with some embodiments. In particular, FIGs. 6A-6B illustrate side view and rear view, respectively of the cargo section 108, in a first scenario 600-1, in accordance with some embodiments. FIGs. 6C-6D illustrates side view and rear view, respectively of the cargo section 108, in a second scenario 600-2, in accordance with some embodiments. FIGs. 6E-6F illustrate side view and rear view, respectively of the cargo section 108, in a third scenario 600-3, in accordance with some embodiments.
[039] The front panel 112 may be rotatable relative to the floor panel 116 via a linkage assembly. The front panel 112 may be rotated manually or via an electric motor or a hydraulic system. The above linkage assembly provides for an effective locking mechanism for holding the front panel 112 at different locations, as per requirement. The linkage assembly may be mounted on front panel 112. As shown in FIGs. 6A-6B, the linkage assembly may include a pair of vertical linkages 602, 604. Each of the pair of vertical linkages 602, 604 may be pivotably coupled to the floor panel 116, via a first end of each of the pair of vertical linkages 602, 604. In particular, the vertical linkage 602 may be pivotably coupled to the floor panel 116, via a first end 602A of the vertical linkage 602, and vertical linkage 604 may be pivotably coupled to the floor panel 116, via a first end 604A of the vertical linkage 604. As such, for example, each of the pair of vertical linkages 602, 604 may be pivotably coupled to the floor panel 116 via a revolute joint. In some embodiments, one end of each of the vertical linkages 602, 604 may be engaged with a hinge solid rod with slots, for locking of the vertical linkages 602, 604.
[040] The linkage assembly may further include a pair of horizontal linkages 606, 608. Each of the pair of horizontal linkages 606, 608 may be pivotably coupled to one of the pair of vertical linkages 602, 604, via a second end of each of the pair of vertical linkages 602, 604 and via a first end of each of the pair of horizontal linkages 606, 608. In particular, the horizontal linkage 606 may be pivotably coupled to the vertical linkage 602, via a second end 602B of the vertical linkage 602 and via a first end 606A of the horizontal linkage 606. The horizontal linkage 608 may be pivotably coupled to the vertical linkage 604, via a second end 604B of the vertical linkage 604 and via a first end 608A of the horizontal linkage 608.
[041] Further, each of the pair of horizontal linkages 606, 608 may be pivoted about a middle point thereof to the front panel 112. In particular, the horizontal linkage 606 may be pivoted about a middle point 610 thereof to the front panel 112, and the horizontal linkage 608 may be pivoted about a middle point 612 thereof to the front panel 112.
[042] The linkage assembly may further include at least one a spring-loaded push-bar coupled with each of the pair of horizontal linkages 606, 608 through a revolute joint, via a second end of each of the pair of horizontal linkages. In some embodiments, as shown in FIG. 6B, the linkage assembly includes one spring-loaded push-bar 614. The spring-loaded push-bar 614 may be coupled with the horizontal linkage 606 through a revolute joint, via a second end 606B of the horizontal linkage 606. The spring-loaded push-bar 614 may be further coupled with the horizontal linkage 608 through the revolute joint, via a second end 608B of the horizontal linkage 608.
[043] The spring-loaded push-bar 614 may by coupled with a spring 616, which may be biased to keep the spring-loaded push-bar 614 extended upwards, as shown in FIG. 6A and FIG. 6E. As such, in order to move the spring-loaded push-bar 614 (as shown in FIG. 6D), a force has to applied against spring 616. The at least one a spring-loaded push-bar 614 may be configured to push against the rear wall 110, when the front panel 112 is configured in the horizontal position, through the spring-loaded push-bar 614 pushed downwards against the spring force of the spring 616. The spring force therefore assists in holding the front panel 112 in the horizontal position. In order to reconfigure the front panel 112, the user may press the spring-loaded push-bar 614 and then rotate the front panel 112 to the required position.
[044] As shown in FIGs. 6A-6B, in the first scenario 600-1, the front panel 112 is configured in vertical configuration. Therefore, the spring-loaded push-bar 614 is not pushed downwards against the spring force of the spring 616.
[045] As shown in FIGs. 6C-6D, in the second scenario 600-2, the front panel 112 is oriented inclined to the vertical (slanted). This is the scenario when the rear wall 110 is positioned in an intermediate position. It should be noted that the rear wall 110 may be enabled to be positioned at different graded positions between a position closest to the front cabin 102 and a position farthest from the cabin section 102. As such, the second scenario 600-2 may correspond to one of the graded intermediate positions of the rear wall 110. As shown in FIGs. 6E-6F, in the third scenario 600-3, the front panel 112 is oriented inclined to the vertical (slanted) and may be touching and pushing against the rear wall 110 is positioned in an intermediate position. Due to pushing against the rear wall 110, the spring-loaded push-bar 614 is pushed downwards against the spring force of the spring 616. When the spring-loaded push-bar 614 is pushed downwards, the pair of horizontal linkages 606, 608 may rotate about the middle points 610, 612, respectively.
[046] In some alternate embodiments, the linkage assembly may include a pair of spring-loaded vertical linkages (corresponding to the vertical linkages 602, 604). Each of these pair of vertical linkages may be pivotably coupled to the floor panel 116, via a first end of each of the pair of vertical linkages. When the front panel 112 is configured in the vertical position, each of the pair of spring-loaded vertical linkages may be configured to push against the rear wall via a second end of each of the pair of vertical linkages.
[047] The rear wall 110 may be caused to longitudinally move relative to the floor 106 of the cabin section 102, for example, by way of application of manual force. To this end, the vehicle may include an adjusting assembly, such that the rear wall 110 is longitudinally moveable relative to the floor 106 of the cabin section 102, via the adjusting assembly. This is explained in detail in conjunction with FIGs. 7A-7B. Referring to FIGs. 7A-7B, side views of the cabin section 102 in different scenarios are illustrated, in accordance with some embodiments. In particular, FIG. 7A illustrates a side view of the cabin section 102, in a first scenario 700-1, in accordance with some embodiments. FIG. 7B illustrates a side view of the cabin section 102, in a second scenario 700-2, in accordance with some embodiments.
[048] In some embodiments, the adjusting assembly may include a first bottom folding linkage 702 pivotably coupled with the floor 106 of the cabin section 102 via a first end 702A of the first bottom folding linkage 702. The adjusting assembly may further include a second bottom folding linkage 704 pivotably coupled with the floor 106 of the cabin section 102 via a second end 704B of the second bottom folding linkage 704. The second bottom folding linkage 704 may be pivotably coupled with the first bottom folding linkage 702 via a first end 704A of the second bottom folding linkage 704 and second end 702B of the first bottom folding linkage 702, via a bottom revolute joint 710. In other words, the first bottom folding linkage 702 and the second bottom folding linkage 704 may be coupled with each other (via the first end 704A of the second bottom folding linkage 704 and second end 702B of the first bottom folding linkage 702) via the bottom revolute joint 710.
[049] The adjusting assembly may further include a first top folding linkage 706 pivotably coupled with a roof 118 of the cabin section 102 via a first end 706A of the first top folding linkage 706. The adjusting assembly may further include a second top folding linkage 708 pivotably coupled with the roof 118 of the cabin section 102 via a second end 708B of the second top folding linkage 708. The second top folding linkage 708 may be pivotably coupled with the first top folding linkage 706 via a first end 708A of the second top folding linkage 708 and a second end 706B of the first top folding linkage 706, via a top revolute joint 712.
[050] The adjusting assembly may further include a rotating lever 714 pivotably coupled with each of the bottom revolute joint 710 and the top revolute joint 712, via a bottom connecting linkage assembly 716 and a top connecting linkage assembly 718, respectively. Upon manipulating the rotating lever 714, the rotating lever 714 may cause to pull or push against the bottom revolute joint 710 and the top revolute joint 712 to thereby longitudinally move the rear wall 110 relative to the floor 106 of the cabin section 102. As shown in FIG. 7A, in the first scenario, the rotating lever 714 is not manipulated and the rear wall 110 is positioned away from the cabin section 102. Further, as shown in FIG. 7B, in the second scenario, the rotating lever 714 is manipulated, which causes the rear wall 110 to be pulled towards the cabins section 102.
[051] It should be noted that the adjusting assembly may not be restricted to the adjusting assembly as described above, and various other modifications of the adjusting assembly may be possible as well. One such modification is described below, on conjunction with FIGs. 8A-8B. In some alternate embodiments, the adjusting assembly may include at least one of a bottom push-pull linkage assembly coupled with the floor via a first end of the bottom push-pull linkage assembly and to the rear wall via a second end of the bottom push-pull linkage assembly, and a top push-pull linkage assembly coupled with the roof via a first end of the top push-pull linkage assembly and to the rear wall via a second end of the top push-pull linkage assembly. In other words, the adjusting assembly may include either or both of the bottom push-pull linkage assembly and the top push-pull linkage assembly. The
[052] FIG. 8A illustrates a side view of the cabin section 102 in a first scenario 800-1, in accordance with some embodiments. FIG. 8B illustrates a side view of the cabin section 102 in a second scenario 800-1, in accordance with some embodiments.
[053] As shown in FIG. 8A, the adjusting assembly may include a bottom push-pull linkage assembly 802 coupled with the floor 106 via a first end 802A of the bottom push-pull linkage assembly 802.
