The following specification particularly describes and ascertains the nature of this invention and the way it is to be performed.
Field of Invention
[001] The invention relates to mounting brackets for batteries. It more particularly relates to mounting bracket for batteries provided on electric vehicles, where the mounting brackets are directly attached to the chassis of said electric vehicles.
Background of the Invention
[002] Battery technology as it exists today, provides less energy density to batteries than any fossil fuel currently in use to operate any IC engine powered vehicles. The range anxiety of customers therefore is addressed by providing larger and heavier batteries on the vehicle. Such heavy batteries, need to be held in a secure arrangement that is light in weight but strong enough to handle any load that may be imposed on it in ordinary operating conditions.
[003] Additionally, in order to maintain stability of the resulting vehicle provided with heavy batteries, the battery and battery mounting arrangement have to be attached centrally at a location that is as close to the ground as possible. This imposes the additional requirement of making it sufficient strong, sturdy and reliable, as in Indian operating conditions the battery cage might encounter different environmental elements that could compromise its integrity, damaging it and the batteries from the outside. As the damage to these components can compromise the safety of the vehicle’s occupants as well, the construction of the entire battery mounting arrangement assumes an even greater significance.
[004] Furthermore, as cost of manufacturing have to be kept reasonable, overall material efficiency also has to be high for any battery mounting arrangement provided on the vehicle. Achieving all these requirements is challenging as they can create contradictory demands on the engineers designing such battery mounting arrangements. Therefore, it is an objective of this invention to provide a battery mounting arrangement for an electric vehicle that is not only light weight, but also strong, sturdy and reliable.
[005] It is another objective of the present invention to provide a battery mounting arrangement that can handle being exposed to different environmental elements without experiencing any damage that can compromise safety of the vehicle occupants.
[006] It is still another objective of the present invention to provide a battery mounting arrangement that is economical to manufacture and provide in an electric vehicle.
Summary of the invention
[007] The invention achieving the stated objectives i.e., the high voltage battery mounting arrangement for buses, comprises of a battery mounting cradle, L hat channel mounting brackets, with L plates and reinforcement plates included in said L hat channel mounting brackets, mounting support brackets. In the high voltage battery mounting arrangement for buses, the battery mounting cradle is mounted and attached on the lower arms of the L hat channel mounting brackets. The L hat channel mounting brackets, evenly distributed on both sides of the battery mounting cradle, are themselves mounted on the left and right chassis long member. The L plate is mounted on the curved portion of the L hat channel mounting brackets. The reinforcement plate are mounted on the front side of the L hat channel mounting brackets. One side of the mounting support brackets is mounted on the L hat channel mounting brackets while the other side is mounted on the chassis long member.

Detailed Description of the Invention
[001] Referring to figures 3, 4a, 5a, and 6a, a high-voltage battery mounting arrangement for buses in accordance with the preferred embodiment of the proposed invention comprises a battery mounting cradle (10), L hat channel mounting brackets (20), with L plates (30) and reinforcement plates (40) being included in said L hat channel mounting brackets (20), and mounting support brackets (50).
[002] The battery mounting cradle (10) (refer Figs. 6a, 6b and 6c) is mounted and attached on the lower arms of the L hat channel mounting brackets (20) (refer Fig. 4a, 4b and 4c). The L hat channel mounting brackets (20), evenly distributed on both sides of the battery mounting cradle (10), are themselves mounted on the left and right chassis long member. The L plate (30) (refer Figs 4a and 5a) is mounted on the curved portion of the L hat channel mounting brackets (20). The reinforcement plate (40) (refer Fig. 5b) are mounted on the front side of the L hat channel mounting brackets (20) (refer Figs 4a, and 4b). One side of the mounting support brackets (20) (Refer Fig. 5c) is mounted on the L hat channel mounting brackets (20) (refer Figs 4a, 4b and 4c) while the other side is mounted on the chassis long member (refer Fig. 2). The L hat channel mounting brackets (20) (Figs. 4a, 4b and 4c) receiving and attaching the brackets (20) provided on middle of the side arms (10S) of the battery mounting cradles (refer Figs. 3, 6a, 6b and 6c) are not provided with the mounting support brackets (50) (refer Fig. 5c).
[003] The L hat channel mounting brackets (20) (refer Figs. 4a, 4b and 4c) have a U-shaped horizontal cut section profile, with rims extending outwards perpendicularly from the ends of the U-shaped central portion. The L hat channel mounting brackets (20) have a long upper arm and a short lower arm. The L hat channel mounting brackets (20) long upper arm transitions into the short lower arm through an intervening curved portion. The L hat channel mounting brackets (20) is provided with openings and depressions (20D) on its body to manage its strength, weight and to facilitate its attachment with other elements of the high voltage battery mounting arrangement.
[004] The battery mounting cradle (10) (refer Figs. 6a, 6b and 6c), has three side arms (10S) (having tube like cut section profile) that are evenly spaced and attached to two vertical arms (10V) (having U-shaped cut section profile). Reinforcing sections (10RS) are attached along the bottom surface of the edges where the side arms (10S) and vertical arms (10V) link up. The ends of the vertical arms (provided with a U-shaped cut section profile) have attachment points provided on their ends.
[005] One member (10R2) each links two opposite edges of the battery mounting cradle (10) such that they are parallel to the corresponding member (10R2) linking the two opposite edges of the neighbouring cell formed by the side arms (10S) and the vertical arms (10V) (refer Fig. 6a). Two short members link (10R1) (refer Fig. 6a) the end portions of the members connecting the two opposite edges of the batter mounting cradle (10) with the vertical arms (10V), such that they are parallel to all the other short members (10R1) similarly linking the end portions of the members (10R2) connecting the two opposite edges of the battery mounting cradle (10).
[006] Triangle shaped reinforcement sections (10R3) are given on the other edges where side arms (10S) and vertical arms (10V) link up (refer Fig. 6a). Three attachment evenly spaced attachment brackets (10SA) with mounting points are given on the outermost side arms of the battery mounting cradle (refer Figs. 6a, 6b and 6c). The high-voltage battery of the electric vehicle that is received on the battery mounting cradle (10) is attached, by means of conventional fasteners, to the mounting points given along the middle and the ends of the side arms (10S) of the battery mounting cradle (10). Conventional fastening means are used at other mounting and attachment points on the high-voltage battery mounting arrangement as well. The disclosed battery mounting arrangement is used to mount the high-voltage battery packs onto the electric vehicles. The conventional fastening means can be nuts and bolts of standard sizes or any other similar fasteners capable of functioning like them.
