[0044] The embodiments of the present application provide a battery pack mounting bracket and a vehicle including the battery pack mounting bracket. It should be noted that the vehicle in the present application may refer to large vehicles, small vehicles, special vehicles, etc. Exemplarily, classified by vehicle type, the vehicle in the present application may be a sedan model, an off-road vehicle model, a multi-purpose vehicle (MPV) model, or other vehicle models. For a vehicle, generally, wheels, a power source, and a transmission system provided between the wheels and the power source are provided. The transmission system can transmit the power provided by the power source to the wheels to make the wheels rotate, thereby driving the vehicle to travel. In the embodiments of the present application, the vehicle may be a new energy vehicle, and the new energy vehicle may use a battery pack as a power source to drive the vehicle to operate.

[0045] Figure 1 It is a schematic structural diagram of the connection between a battery pack and a vehicle provided by the embodiments of the present application.

[0046] See Figure 1 As shown, the vehicle may include a battery pack 300, a rear floor cross member 200, and a front floor 400. The battery pack 300 may be connected to the rear floor cross member 200 of the vehicle through a mounting bracket 100 to realize the installation of the battery pack 300 on the vehicle. For example, one end of the mounting bracket 100 is connected to the rear floor cross member 200, and one end is connected to the battery pack 300.

[0047] As described in the above background art content, for vehicle models on the same platform, the wheelbase adjustment is generally achieved by moving the rear floor forward or backward, and lengthening or shortening the rear section of the front floor and the sill. The battery pack is arranged under the front floor, and the arrangement position of the battery pack generally remains unchanged. For the installation of the battery pack of a vehicle with a long wheelbase, it is usually necessary to lengthen the battery pack mounting bracket so that the battery pack can be connected to the rear floor cross member through the mounting bracket.

[0048] However, after the mounting bracket is lengthened, the bending resistance of the battery pack mounting bracket will be reduced, thereby affecting the support effect on the battery pack.

[0049] To solve the above problems, an embodiment of the present application provides a battery pack mounting bracket. By providing a reinforcing member in the mounting bracket and connecting the reinforcing member to the front floor, the portion where the reinforcing member is in contact with and connected to the bracket body can increase the structural strength of the corresponding part of the bracket body, which helps to improve the overall bending resistance of the mounting bracket, thereby effectively improving the overall structural strength and stability of the mounting bracket and enhancing the support effect on the battery pack. Moreover, since the reinforcing member is connected to the front floor, the bracket body can be connected to the front floor through the reinforcing member, enabling the bracket body to be fixed through the reinforcing member and the front floor. This can effectively improve the reliability and firmness of the connection between the bracket body and the vehicle, effectively improve the overall structural stability of the mounting bracket, enhance the bending resistance and deformation resistance of the mounting bracket, and thus effectively enhance the support effect of the mounting bracket on the battery pack.

[0050] The following will describe in detail the battery pack mounting bracket provided by the embodiment of the present application with reference to the accompanying drawings.

[0051] Figure 2 FIG. is a schematic structural diagram of a battery pack mounting bracket provided by an embodiment of the present application connected to a rear floor cross member. Figure 3 FIG. is a schematic structural diagram of a battery pack mounting bracket provided by an embodiment of the present application connected to a battery pack and a rear floor cross member.

[0052] An embodiment of the present application provides a battery pack mounting bracket 100. Referring to Figure 2 and Figure 3 as shown, the battery pack mounting bracket 100 may include a bracket body 110 and a reinforcing member 120. One end of the bracket body 110 may be used to connect to the rear floor cross member 200 of the vehicle, and the other end may be used to connect to the battery pack 300. For example, the bracket body 110 may be connected to the rear floor cross member 200 and the battery pack 300 by welding, so that the battery pack 300 can be connected to the rear floor cross member 200 through the bracket body 110.

[0053] At least a part of the reinforcing member 120 can be attached to and connected with the bracket body 110, and the reinforcing member 120 can also be connected with the front floor 400 of the vehicle. The part where the reinforcing member 120 is attached to and connected with the bracket body 110 can increase the structural strength of the corresponding part of the bracket body 110, which helps to improve the overall bending resistance of the mounting bracket 100, thereby effectively improving the overall structural strength and stability of the mounting bracket 100 and enhancing the supporting effect on the battery pack 300. Moreover, since the reinforcing member 120 is connected with the front floor 400, the bracket body 110 can be connected with the front floor 400 through the reinforcing member 120, so that the bracket body 110 can be fixed through the reinforcing member 120 and the front floor 400. In this way, the reliability and firmness of the connection between the bracket body 110 and the vehicle can be effectively improved, the overall structural stability of the mounting bracket 100 can be effectively improved, and the bending resistance and deformation resistance of the mounting bracket 100 can be enhanced, thereby effectively enhancing the supporting effect of the mounting bracket 100 on the battery pack 300.

[0054] Figure 4 The front view of a battery pack mounting bracket provided by an embodiment of the present application Figure 5 is Figure 4 the view from direction A in Figure 6 is Figure 4 the sectional view taken along line B-B in

[0055] Continuing to refer to Figure 4 and Figure 5 as shown, the bracket body 110 can include a first bottom plate 111 and first side plates 112 surrounding both sides of the first bottom plate 111. The reinforcing member 120 can include a second bottom plate 121 and second side plates 122 surrounding the second bottom plate 121. The first bottom plate 111 and the first side plates 112 can jointly enclose to form a receiving area 113. The reinforcing member 120 can be located within the receiving area 113, and moreover, the second bottom plate 121 of the reinforcing member 120 can be attached to and connected with the first bottom plate 111, and the second side plates 122 can be connected with the front floor 400.

[0056] For example, the first bottom plate 111 and the second bottom plate 121 can be connected by welding (such as spot welding). The battery pack 300 can be connected with the first bottom plate 111 of the bracket body 110. For example, the battery pack 300 can be connected to the side of the first bottom plate 111 facing away from the receiving cavity. The attachment and connection between the first bottom plate 111 and the second bottom plate 121 can improve the structural strength of the corresponding part of the first bottom plate 111, enhance the overall structural stability and bending resistance of the bracket body 110, and thereby effectively enhance the supporting effect on the battery pack 300.

[0057] The connection between the second side plate 122 and the front floor 400 can improve the firmness and reliability of the reinforcement 120, contribute to enhancing the reliability of the connection between the bracket body 110 and the front floor 400, and thus effectively improve the structural stability and reliability of the mounting bracket 100.

[0058] See Figure 6 As shown, the reinforcement 120 may further include a nut member 130. Coaxial connection holes 103 may be formed at the connected parts of the reinforcement 120 and the bracket body 110 (in combination with Figure 4 as shown). The nut member 130 may be welded to the reinforcement 120 and coaxial with the connection hole 103. The nut member 130 may be used to connect with the battery pack 300.

[0059] For example, the battery pack 300 may have a mating hole that mates with the nut member 130. A bolt fastener may sequentially pass through the mating hole on the battery pack 300, the connection hole 103, and be screwed into the nut member 130 to mate with the nut member 130, so that the battery pack 300 can be connected to the mounting bracket 100 through the cooperation of the bolt fastener and the nut member 130, and thus the battery pack 300 can be connected to the vehicle through the mounting bracket 100. This can facilitate the installation and removal of the battery, effectively improve the reliability and firmness of the connection between the battery pack 300 and the vehicle, and facilitate the subsequent maintenance and replacement of the battery pack 300.

[0060] Figure 7 It is a schematic structural diagram of the connection between a battery mounting bracket and a vehicle provided by an embodiment of the present application.

[0061] See Figure 7 As shown, the bracket body 110 may include a connected first connection portion 101 and a second connection portion 102. The first connection portion 101 and the second connection portion 102 may be arranged at an angle. Among them, the first connection portion 101 may be used to connect with the front floor 400 of the vehicle, and the second connection portion 102 may be used to connect with the rear floor cross beam 200. This can connect both ends of the bracket body 110 to the rear floor cross beam 200 and the front floor 400 respectively, effectively improving the firmness and reliability of the connection between the bracket body 110 and the vehicle, contributing to improving the overall structural stability of the mounting bracket 100, and thus effectively improving the support effect on the battery pack 300.

[0062] Continue to refer to Figure 6 and Figure 7As shown, the first side plate 112 of the bracket body 110 may further have a first flanging structure 114. The first connecting portion 101 and the second connecting portion 102 may both have the first flanging structure 114. The first flanging structure 114 may be used to connect to the rear floor crossbeam 200 and the front floor 400 of the vehicle. The bracket body 110 may also be connected to the front floor 400 of the vehicle through the flanging structure, which can effectively improve the firmness and reliability of the connection between the bracket body 110 and the vehicle, thereby effectively improving the reliability and stability of the battery support of the mounting bracket 100.

[0063] For example, the first flanging structure 114 may be connected to the rear floor crossbeam 200 and the front floor 400 by welding (e.g., spot welding). The first flanging structure 114 may facilitate the fitting with the rear floor crossbeam 200 and the front floor 400, and can increase the contact area of the connection between the bracket body 110 and the rear floor crossbeam 200 and the front floor 400, which is convenient for welding operations and helps to improve the firmness and reliability of the connection between the bracket body 110 and the rear floor crossbeam 200 and the front floor 400.

[0064] Continue to refer to Figure 6 and Figure 7 As shown, the second side plate 122 of the reinforcing member 120 may further have a second flanging structure 123. The second flanging structure 123 may be used to connect to the front floor 400, so that the reinforcing member 120 can be connected to the front floor 400 through the second flanging structure 123. For example, the second flanging structure 123 may be connected to the front floor 400 by welding (e.g., spot welding). The second flanging structure 123 may facilitate the fitting with the front floor 400, and can increase the contact area of the connection between the reinforcing member 120 and the front floor 400, which is convenient for welding operations and helps to improve the firmness and reliability of the connection between the reinforcing member 120 and the front floor 400.

[0065] Refer to Figure 4 As shown, an avoidance hole 1111 may be provided on the first bottom plate 111 of the bracket body 110. The avoidance hole 1111 may be opposite to the second flanging structure 123 located in the accommodation cavity of the reinforcing member 120. When welding the second flanging structure 123 to the front floor 400, the welding tool may pass through the avoidance hole 1111 to weld the second flanging structure 123 located in the accommodation area 113. The avoidance hole 1111 can prevent the first bottom plate 111 from blocking the second flanging structure 123, which is convenient for the connection between the flanging structure and the front floor 400, helps to improve the operability of the connection between the second flanging structure 123 and the front floor 400, and enhances the reliability and stability of the connection between the second flanging structure 123 and the front floor 400.

[0066] Refer to Figure 5 andFigure 6 As shown, one end of the bracket body 110 connected to the battery pack 300 may also have an opening 115, and the opening 115 may be located between two adjacent first side plates 112. In other words, it can be understood that the first side plates 112 do not form a closed loop enclosure on the first bottom plate 111, and there is no first side plate 112 at one end edge of the first bottom plate 111. This can facilitate the stamping forming of the reinforcing member 120 and facilitate the demolding of the reinforcing member 120.

[0067] Moreover, since there is no first side plate 112 at the end of the bracket body 110 having the opening 115, the length of the bracket body 110 can also be reduced, thereby reducing the space occupied by the bracket body 110 in the vehicle length direction, which is beneficial to the layout of the mounting bracket 100 in the vehicle.

[0068] The serial numbers of the embodiments of the present application above are only for description and do not represent the advantages and disadvantages of the embodiments. The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
