FRAME STRUCTURE OF AN ELECTRIC VEHICLE

HERO MOTOCORP LIMITED, an Indian Company at: The Grand Plaza, Plot No.2, Nelson Mandela Road, Vasant Kunj- Phase -II, New Delhi, India, 110 070

THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

FIELD OF THE INVENTION:
[001] The present invention relates to a frame structure of a vehicle, more particularly to a frame structure of an electric vehicle.

BACKGROUND OF THE INVENTION:
[002] A frame structure is an essential part of a vehicle and traditionally were originally designed to accommodate internal combustion engines and their associated vehicular components. However, with the recent developments in field of electric vehicles, the role of the frame structure has been tremendously changed. For example, the electric vehicle comprises a battery accommodating structure mounted on the frame structure for accommodating a battery providing power to the electric vehicle. Conventionally, the battery accommodating structure is mounted on the frame structure via an attachment structure transferring the weight of the battery and the battery accommodating structure to the frame structure.

[003] In one option, the attachment structure is mounted on the frame structure by using mounting elements such as fasteners. Thus, there is chance that the mounting element may fail due to higher weight of the batteries, which in turns results in unmounting of the battery accommodating from the frame structure. In addition to that mounting of attachment structure over the frame structure requires more time leading to an increase in assembling time of the vehicle in a production facility. In other option, the attachment structure may be directly connected to the frame structure, particularly on a lower frame of the frame structure. Since, the lower frame comprises a bent portion, connecting the attachment structure on the lower frame may lead to less joining strength in between the attachment structure and the lower frame, an undesired orientation of attachment structure with respect to the frame structure and other problems known to a person skilled in the art. Further, there is also a need that the frame structure allow the battery accommodating structure to exhibit a pivotal movement in a width direction of the vehicle in order to make battery removal and installation process easy.

[004] Thus, there is a requirement of providing a solution to one or more than one of aforementioned problems.

In an embodiment of the invention, the first edge (148) and the seventh portion (152) being joined to the third portion (140), the fourth portion (142) and the fifth portion (144). The connection of the first edge (148) and the seventh portion (152) with the first bracket part (130), provides a better joining strength in between the second bracket part (132) and the first bracket part (130). And, also prohibits any dislocation of the second bracket part (132) with respect to the first bracket part (130).

[0052] Although, the location of the first bracket part (130) with respect to the second bracket part (132) may get changed as per requirement. In a preferred embodiment of the invention, the first edge (148) is connected to one of the first section (134) and the third section (138) of the first bracket part (130) and seventh portion (152) is joined to the second section (136) of the first bracket (130).

[0053] In another embodiment of the invention, the eighth portion (154) is joined to the third portion (140) and the ninth portion (156) is joined to the fourth portion (142), which further provides an extra joining strength between the first bracket part (130) and the second bracket part (132) leading to an enhanced weight bearing capacity of the attachment structure (114).

[0054] In an embodiment of the invention, the eighth portion (154) defines a first receiving portion (158) in between the first edge (148) and the second edge (150) along the first side of the sixth portion (146) and the ninth portion (156) defines a second receiving portion (160) in between the first edge (148) and the second edge (150) along the second side of the sixth portion (146). The first receiving portion (158) receives the first pivot axis defining element (126) and the second receiving portion (160) receives the second pivot axis defining element (128).

[0055] In an embodiment of the invention, the attachment structure (114) may be constructed as a single unit and adaptable to be connected to the lower frame (106) via one of a permanent joint and a temporary joint. In an alternative embodiment of the invention, the attachment structure (114) being formed as an integral part of the lower frame (106). However, in an option the attachment structure (114) can be adaptable to be connected to the lower frame (106) via the temporary joints, which increases the adaptability of the invention. But, in a preferred embodiment of the invention, the attachment structure (114) should be connected to the lower frame (106) via the permanent joints or made as the integral part of the frame structure (100) so as to obtain maximum joining strength in between the attachment structure (114) and the lower frame (106).

[0056] Now coming to an aspect of mounting the battery accommodating structure on the frame structure (100). In an exemplary embodiment of the invention, the first battery accommodating structure (44) comprises at least one first connecting mechanism (Not shown) interacting with the first pivot axis defining element (126) for allowing coupling of the first battery accommodating structure (44) to the attachment structure (114) from the first side. Similarly, the second battery accommodating structure (46) comprises at least one second connecting mechanism (Not shown) interacting with the second pivot axis defining element (128) for allowing coupling of the second battery accommodating structure (46) to the attachment structure (114) from the second side.

[0057] Since, the attachment structure is connected with the lower frame at multiple location leading to more contacting area and joining strength. One of the advantages of the present invention is that, the frame structure allows mounting of batteries having less weight or higher weight and larger size without failing. Since, the frame structure comprises only a single lower frame in comparison to other existing frame structure having two lower frames. One of the advantages of the present invention includes a reduction in weight of the vehicle ultimately leading to an enhancement in vehicular performance and reduction in manufacturing cost of the vehicle.

[0058] Since, the frame structure is adaptable to pivotably couple the battery accommodating structure, the battery accommodating structure can perform a pivotal movement in a width direction of the vehicle, which allows a user to bring the battery accommodating structure at a position that facilitates an easy removal and installation of the battery. Since, mounting of the battery accommodating structure on the frame involves only one component i.e., pivot axis defining element. Thus, one of the advantages of the present invention includes a reduction in time and effort required for assembling the battery accommodating structure on the vehicle.

[0059] Since, the attachment structure (114) is adaptable to be connected to the lower frame (106) via the permanent joints or may be formed as the integral part of the frame structure (100). One advantage of the present invention includes removing a step involving mounting of the attachment structure (114) on the frame structure (100) leading to a decrease in an assembling time of the vehicle in a production facility.
