In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0032] At present, a vehicle includes a frame and a battery pack disposed on the frame, and the battery pack is connected to the frame through a connector. However, the strength of the connection between the connector and the frame and the battery pack is low, and it is easy to deform and break, resulting in low safety performance of the vehicle. Therefore, the utility model proposes a vehicle, which aims to improve the strength of the connection between the connector and the frame and the battery pack, so that the safety performance of the vehicle is higher.

[0033] Reference Figures 1 to 5In one embodiment of the utility model, the vehicle includes a frame 100, a battery pack 200, and a mounting bracket 300. The battery pack 200 is disposed below the frame 100. The mounting bracket 300 connects the frame 100 and the battery pack 200. The mounting bracket 300 includes a connecting frame 400. The connecting frame 400 includes a connecting member 401 and a reinforcing member 500. The connecting member 401 includes a first connecting section 410 connected to the frame 100 and a second connecting section 420 connected to the battery pack 200. The reinforcing member 500 includes a first reinforcing section 510 disposed at the first connecting section 410 and a second reinforcing section 520 disposed at the second connecting section 420. In this way, the structural strength of the first connecting section 410 is enhanced by the first reinforcing section 510, so that the strength of the connection between the connecting member 401 and the frame 100 is higher, so that the first connecting section 410 is not easy to deform, so that the connecting member 401 is not easy to break, and thus the vehicle has higher safety performance. In addition, the second reinforcing section 520 is used to enhance the structural strength of the second connecting section 420, so that the strength of the connection between the connecting member 401 and the battery pack 200 is higher, so that the second connecting section 420 is not easy to deform, and the connecting member 401 is not easy to break, so that the vehicle has higher safety performance. Furthermore, since the reinforcing member 500 includes the first reinforcing section 510 and the second reinforcing section 520, that is, the structural strength of the first connecting section 410 and the second connecting section 420 of the connecting member 401 can be improved by a reinforcing member 500, it is beneficial to reduce the number of parts used in the vehicle and to simplify the structure of the vehicle.

[0034] Refer to Figure 6There are many structural forms of the connecting member 401 and the reinforcement member 500. Optionally, in one embodiment, the first connecting section 410 is provided with a reinforcement groove 411 extending in the up-down direction, the second connecting section 420 is arranged at the lower end of the reinforcement groove 411, the reinforcement member 500 is arranged in the reinforcement groove 411, the reinforcement groove 411 has a groove bottom and a notch opposite to the groove bottom, the first reinforcement section 510 is arranged at the notch, the reinforcement member 500 also includes an avoidance section 530 connecting the lower side edge of the first reinforcement section 510 and the side edge of the second reinforcement section 520 close to the groove bottom, the vehicle also includes a first fastener 710 penetrating the second reinforcement section 520 and the second connecting section 420, and a second fastener 720 penetrating the first reinforcement section 510, the first connecting section 410 and the battery pack, the avoidance section 530 and the second reinforcement section 520 limit an avoidance space 540 for the first fastener 710 to enter and exit in the up-down direction. It can be understood that the first reinforcement section 510 and the first connecting section 410 enclose a reinforcement cavity, so that the weight of the mounting bracket 300 is reduced and the structural strength of the mounting bracket 300 is increased. In addition, the avoidance space 540 is provided to facilitate the disassembly and assembly of the first fastener 710 to the second connecting section 420 and the second reinforcement section 520. The first fastener 710 and the second fastener 720 can be configured as components such as screws, but are not limited to being configured, and are not limited here. The first connecting section 410 and the first reinforcement section 510 are connected to the battery pack 200 with other parts through the first fastener 710, such as connecting to the adapter frame 800 mentioned later, or directly connected to the battery pack 200. However, the present design is not limited to this. In other embodiments, the structural form of the connector 401 and the reinforcement 500 can also be other, as long as the reinforcement 500 can reinforce the connector 401.

[0035] There are many structural forms of the avoidance section 530. Optionally, in one embodiment, the avoidance section 530 includes a first avoidance section 531 connected to the lower side edge of the first reinforcement section 510, and a second avoidance section 532 connected to the side edge of the second reinforcement section 520 near the bottom of the groove.

The first avoidance section 531 is tilted downward in the direction close to the bottom of the groove, and the second avoidance section 532 is arranged in parallel with the bottom of the groove and is arranged at the bottom of the groove. In this way, the avoidance section 530 has a higher structural strength, and the avoidance space 540 limited by the avoidance section 530 and the second reinforcement section 520 in the vertical direction is larger in the vertical direction, so as to facilitate the first fastener 710 to enter and exit. However, the present design is not limited to this. In other embodiments, the avoidance section 530 is tilted toward the second reinforcement section 520 in the direction close to the first connection section 410.

[0036] Optionally, in one embodiment, the avoidance section 530 is provided with a reinforcing rib 533 protruding toward the notch, so as to further improve the structural strength of the avoidance section 530 and thus improve the structural strength of the connecting member 401 .

In this way, the structural strength of the connecting member 401 is improved, and the structural strength of the reinforcement member 500 is improved. In addition, the setting of the flange 561 will not increase the space occupied by the mounting bracket 300, which is conducive to the miniaturization of the mounting bracket 300. However, the present design is not limited to this. In other embodiments, the two weight-reducing holes 560 are arranged opposite to each other in the groove depth direction of the reinforcement groove 411, and the periphery of one of the two weight-reducing holes 560 is provided with a flange 561 extending away from the other.

In this way, the tube body 600 improves the torsional strength of the connection member 401 and the reinforcement member 500. In addition, the tube body 600 also provides a guide for the second fastener 720 and improves the stress generated when the second fastener 720 is installed. The second fastener 720 can be configured as, but not limited to, a screw or other member.

In this way, on the one hand, the left and right sides of the battery pack 200 are provided with mounting brackets 300 to provide upward pulling force, so that the battery pack 200 is subjected to a more uniform force, so that the battery pack 200 is connected to the vehicle frame 100 more stably. On the other hand, it is helpful to save the bracket under the battery pack 200 for supporting the battery pack 200, so as to reduce the cost of the vehicle. However, the present design is not limited to this. In other embodiments, the mounting bracket 300 is connected to the bottom of the battery pack 200 to support the battery pack 200, so that the battery pack 200 is connected to the vehicle frame 100 more stably.
