TECHNICAL FIELD
The present disclosure generally relates to field of automobiles. Particularly, but not exclusively, the present disclosure relates to a headlight beam adjuster assembly for a vehicle. Further embodiments of the present disclosure disclose a headlight beam adjuster assembly of an automobile with provisions for enhanced accessibility.

BACKGROUND OF THE DISCLOSURE

Generally, vehicles are provided with headlights [also referred to as “headlamps”] secured at the fore end. The headlights may be selectively operated for the purposes of visibility and indication during dark conditions. A conventional headlight assembly comprises a lamp removably mounted in a housing, and may be connected to a power source, like a battery of the vehicle through a wiring harness. The lamp, upon supplying power, emits a beam of light which may illuminate regions ahead of the vehicle for visibility. The illumination of region ahead of the vehicle facilitates visibility to an user or driver to manuevre the vehicle in dark conditions. In addition, a beam of light may be used to alert a driver of a vehicle advancing from opposite direction, as well as to provide indications to other vehicles travelling in same direction, during circumstances, like overtaking. Conventionally, headlamp fitted to vehicle may be configured to emit light beam at a specific angle or azimuth, so that the region ahead may be appropriately illuminated. At the same time, no inconvenience is caused to occupants of vehicles coming from opposite direction. The angle or range of illumination from the headlight may vary from vehicle to vehicle and such angle may be fixed or adjusted based on vehicle parameters.

In most of the conventional vehicles, the headlight assemblies are arranged or assembled in a pocket or provision formed in a vehicle body, such that at least a part of the headlight assembly occupies the pocket. Though headlight assemblies for a particular vehicle are made standard, the illumination range or angle of the headlight may change due to unavoidable variations in the pockets or provisions in the vehicle body accommodating the headlight. Considering the above, the vehicle manufacturers generally provide an adjuster mechanism, which usually may be located at the rear end of the headlight housing. The mechanism may comprise a bolt connected with a beam holder for driving an adjuster rod to adjust the angular displacement of the headlight in at least one of up-down or right-left directions. During the assembly or after the production of the vehicle, the maintenance personnel may operate the adjusting mechanism to tilt the headlight beam to a desired angle, such that the target illumination range or angle is obtained.

One such conventional adjuster assembly is illustrated in FIGS. 1 and 2. The conventional headlight beam adjuster 10 has a housing body 12 and an adjuster element 16 which facilitates adjustment of the beam being emitted by the headlight [not shown]. The housing body 12 also comprises a plurality of mounting members 18 which project from the periphery. The mounting members 18 allow the adjuster 10 to be mounted or assembled onto the headlight structure. As shown in FIG. 1, the adjuster element 16 comprises a provision 16A which may accommodate a mechanical element or a tool for the purpose of actuation. For example, the provision 16A may include a socket or a groove of predefined geometry and capable of accommodating a tool or a mechanical element. The tool or the element may be driven in preferred direction for rotating internal mechanisms [not shown] of the adjuster element 16. Upon driving the provision 16A, torque is transmitted to the shaft 14 of the adjuster 10 through the internal mechanisms. Depending on the torque applied, the actuating shaft 14 adjusts the beam. However, the conventional adjuster assemblies pose certain practical challenges. One such problem may include compatibility issues with different models or variations of the headlamps. Hence, these adjusters 10 do not meet customized requirements of headlight manufacturing and assembly plants, and have to be manufactured individually to meet design requirements of each model. Another limitation of the conventional adjuster assembly 10 may include limited accessibility to adjuster element for adjusting. For example, as shown in FIG. 1, the laterally extending adjuster element 16 may be accessible only from one direction, and accessibility may dependent on the orientation of the adjuster 10 with respect to the headlight structure. This may render the adjuster element 16 inaccessible or might pose the challenge of difficulty in accessibility for performing the beam adjustment. Hence, a new configuration of adjuster assembly is required to be developed for every variation of vehicle. In either case, the headlight beam adjustment becomes tedious and time consuming, resulting in increased service time.

The present disclosure is directed to overcome one or more limitations stated above.

Reference will now be made to the exemplary embodiments of the disclosure, as illustrated in the accompanying drawings. Wherever possible same referral numerals will be used to refer to the same or like parts.

FIGS. 3 and 4 are exemplary embodiments of the present disclosure illustrating perspective views of a headlight beam adjuster assembly (20) for a vehicle [not shown]. The headlight beam adjuster assembly (20) [alternatively referred to as “adjuster (20)” throughout the specification for the purpose of simplicity] may be assembled with headlight structure of the vehicle for performing adjustment operations such as beam angle of the light emitted from the lamp and range of the headlight beam. The adjuster assembly (20) comprises a housing (21) securable to a frame [not shown] of the headlight structure. The housing (21) encloses the components constituting the adjuster assembly (20). As shown in FIGS. 3 and 4, the housing (21) may comprise at least one flange (21A) which may be secured to the frame [not shown] of the headlight structure for holding the adjuster (20) firmly with respect to the structure. In an embodiment, the at least one flange (21A) may be secured to the frame by fastening, as depicted in FIGS. 3 and 4. In an embodiment of the present disclosure, the adjuster assembly (20) may be configured in front compartment of the vehicle, so that the adjuster (20) may be accessible through the front compartment. This allows the initial setting of the beam at the time of the headlight after production of the vehicle, as well as during beam adjustments whenever need arises for the same.

The housing (21) also supports an adjusting element (22) which is a member that may be imparted with torque for performing beam adjusting. In an embodiment, the adjusting element (22) may be disposed laterally to axis of the output shaft (28) or may be disposed in the direction of axis of the output shaft (28). FIG. 3 shows, the adjusting element (22) disposed in the direction of the axis of the output shaft (28). The adjusting element (22) comprises a first portion or a head portion (22A) having at least one first provision (23) formed in it. The head portion (22A) may accommodate a tool or a mechanical element like a key, for applying the torque to actuate i.e. rotate the adjusting element (22) in desired direction. In an embodiment, the first provision (23) is at least one of a slot or socket or bore or a hole or a pocket of predefined geometry [like a hexagonal pocket as shown in FIG. 4] formed in head portion (22A) of the adjusting element (22). A tool like a screw driver which matches with profile of the first provision (23), or a mechanical element like a key [for example, hexagonal shaped Allen key] may be inserted in the first provision (23) for applying torque. Application of torque results in rotation of the adjusting element (22), which may be utilised in adjusting the headlight beam which will be explained in detail in forthcoming paragraphs. Thus, the first provision (23) provides accessibility to the adjusting element (22) from a first direction to perform headlight beam adjusting.
Referring again to FIGS. 3 and 4, the adjusting element (22) further comprises a second portion or flanged portion (22B) below the first portion (22a). The second portion (22B) which may be configured with a plurality of second provisions (24) [referred to as second “provisions (24)” for simplicity], including but not limited to toothed projections such as gear teeth, splines, threads, leads or detents. The second provisions (24) may be applied with torque to rotate the adjusting element (22). In an embodiment, the second provisions (24) may be integrally manufactured with the adjusting element (22), or may be an external component like a gear that may be affixed to the adjusting element (22) by known joining techniques. The presence of second provisions (24), therefore, allows the adjusting element (22) to be operated whenever the first provision (23) is not accessible, or in circumstances like non-availability of tools or mechanical elements to drive the first provision (23). The actuation [i.e. rotation] of adjusting element (22) through the second provisions (24) may be achieved by using tools or mechanical elements or any other member which serves the purpose. For example, if the second provisions (24) are plurality of teeth [as depicted in FIG. 4], then a tool comprising a pinion whose teeth can engage with teeth constituting the second provisions (24) may be employed for rotation. Similarly, if the second provisions (24) are splines, leads, threads or detents, appropriate mating members may be employed to impart rotary motion to the adjusting element (22) through second provisions (24). Since the second provisions (24) are configured along the periphery of the flanged portion (22B) of the adjusting element (22), the adjusting element (22) can be accessed from all the directions and can be imparted with torque from all the directions.

In an embodiment, the second provisions (24) may be accessed by the tool in a direction perpendicular to the direction of access of the first provision (23). The second provisions (24) having gear teeth profile may be rotated by a tool [like a screw driver having gear toothed tip or a star screw driver] or a mechanical element like a key having a toothed tip which matches with the profile of the second provisions (24). In an another embodiment, the adjusting element (22) carrying the second provisions (24) may be configured with one or more ports or access ports (25) for providing accessibility to the second provisions (24). The arrangement is such that the adjusting element (22) carrying the second provisions (24) is engagingly disposed with the at least one access port (25). In an embodiment of the present disclosure as depicted in FIG. 4, the access port (25) may include a plurality of channels which extend towards the second provisions (24) from a predetermined point through a predetermined distance. When the adjusting element (22) is to be rotated, the tool or the mechanical element may be guided through one or more channels of the access port (25). In an embodiment of the present disclosure, the second provisions (24) include spur gear teeth which may be actuated by a mating gear having identical spur gear module, or by a rack having spur gear teeth extending linearly at an angle with respect to the second provisions (24). In an embodiment of the present disclosure, each of the at least one access port (25) is defined in the housing (21) and may extend transversely with respect to the longitudinal axis of the adjuster element (22). This way, the access port (24) allows the adjuster element (22) to be accessed through the second provisions (24) for performing the headlight beam adjustment. In an embodiment, the access ports (25) allows a user to actuate the adjuster element (22) through the second provisions (24) for beam adjustment, when the first provision (23) has limited accessibility or not accessible due to assembly or space constraints.

FIG. 5 is an exemplary embodiment of the present disclosure which illustrates bottom view of the adjuster assembly (20) of FIGS. 3 and 4. Reference is also made to FIG. 5A which is the sectional view of adjuster assembly (20) along section A-A in FIG. 5. As shown in FIG. 5, the housing (21) of the adjuster assembly (20) comprises at least one securing means (27) for mounting or securing the adjuster assembly (20) with respect to headlight structure. In an embodiment, the securing means (27) include but not limited to lugs, snaps or projections which project from at least a portion of outer periphery of the housing (21) body, as shown in FIG. 5. The securing means (27) allow the adjuster (20) to be mounted with respect to the headlight beam body. In an embodiment, the securing means (27) facilitates the adjuster (20) to be connected to the headlight body, such that the output shaft (28) of the adjuster (20) contacts the headlight body to actuate it. The actuation of the headlight body may cause adjustment of the headlight beam. In an embodiment of the present disclosure, the securing means (27) snaps with the headlight body for connectivity.

Now referring to FIG. 5A, transmission of motion from adjusting element (22) to the output shaft (28) through the mechanism (26) is described. Reference is also made to FIGS. 6-8 which illustrate perspective and top views of a portion of mechanism (26), in conjunction with FIG. 5A. The adjusting element (22) comprising the first provision (23), the second provisions (24) and proximally disposed access ports (25) are held in a portion of the housing (21), such as a bore in the housing (21), as depicted in FIG. 5A. A body (22C) of the adjusting element (22) extends into the bore in the housing. The body (22C) is configured as an input shaft and comprises engaging means (22D) [best shown in FIG. 6], including but not limited to gear teeth, splines, pitched threads, leads and the like to transmit motion to the component engaging with it. On the other hand, the mechanism (26) comprising a plurality of drives may be provisioned in housing (21) adjacent to the adjusting element (22). In an embodiment as depicted in FIG. 5A, the mechanism (26) may be provisioned engagingly and parallelly with respect to the adjusting element (22). When the adjusting element (22) is actuated by imparting torque either through the first provision (23) or through the second provisions (24), the body portion (22C) comprising the input shaft rotates and transmits motion to the component engaging with it through the engaging means (22D). In an embodiment of the present disclosure, the component engaging with the engaging means (22D) includes but not limited to a driven member (29A) like a gear drive, a splined shaft, a threaded member, a member configured with leads, worms and the like. For the purpose of illustration, the driven member (29A) is depicted as a gear drive (29A) in FIGS. 6 and 7, and should not be construed as limitation to the present disclosure. The adjusting element (22), when imparted with torque, drives the driven member (29A) due to meshing engagement. The meshing engagement is clearly depicted in FIG. 7. Depending on gear ratio of meshing teeth, the driven member (29A) rotates with a predetermined angular speed. Further, as depicted in FIG. 8, the driven member (29A) may include internal teeth (30) which may engage with an internal drive member (32). As it can be seen, the internal drive member (32) also comprises teeth (32A) which may mesh with the internal teeth (30) of the driven member (29A). Due to internal meshing, the driven member (29A) and internal drive member (32) rotate in the same direction. The internal drive member (32) may further comprise inner provisions (32B, 32C) to secure a drive shaft (29C) through frictional force [shown in FIG. 5A]. In an embodiment of the present disclosure, the internal drive member (32) includes but not limited to a ring gear having external teeth (32A) which may mesh with internal teeth (30) of the driven member (29A).

In operation, when the body portion (22C) or the input shaft [hereafter referred to as “input shaft (22C)”] is rotated either through the first provision (23) or through second provisions (24), rotary motion is transmitted to the mechanism (26) via engaging means (22D). The mechanism (26) comprises driven member (29A), internal drive (32), the drive shaft (29C) and the output shaft (28), as shown in FIG. 5A. As the assembly (20) of the present disclosure, facilitates access of the adjusting element (22) through the first provision (23) or the second provisions (24), the accessibility of the adjusting element (22) is enhanced and thus, the beam of the headlight may be adjusted through multiple directions irrespective of space constraint or the type of vehicle. The rotation of the driven member (29A) by the input shaft (22C) in turn causes rotation of the internal drive member (32). The internal drive member (32) which engages with the drive shaft (29C) through internal provisions (32B, 32C), drives the drive shaft (29C). The drive shaft (29C) may comprise mating profile [not shown] which may engage with the inner provisions (32B, 32C) of the internal drive member (32A). The drive shaft (29C) may further drive the output shaft (28) for actuating the output shaft (28). In an embodiment of the present disclosure, the drive shaft (29C) may comprise at least one of leads, threads, splines, teeth and the like capable of engaging with the output shaft (28). Accordingly, the output shaft (28) may comprise corresponding leads, threads, splines or teeth which may engage with those of the drive shaft (29C). In an embodiment, the output shaft (28) may be imparted with torque by the drive shaft (29C) to provide at least one of rotary motion and linear motion, or a combination of rotary and linear [reciprocating] motions. In an embodiment of the present disclosure, the output shaft (28) may be loaded with a resilient member (29D) like a spring for aiding the actuation. The rotary or linear motion of the output shaft (28) operates the headlight, like a deflector [not shown] to perform the beam adjustment, for example, the beam angle or azimuth. The motion of the output shaft (28) may be reversed by applying torque to the adjuster element (22) in opposite direction.

In an embodiment, the assembly (20) of the present disclosure is simple in construction, easy to assemble, and can be accessible from any direction. This make the assembly universal, and can be employed in any vehicle configuration.
