[0036] At present, a vehicle includes a frame and a battery pack arranged on the frame, and the battery pack is connected to the frame through a connecting frame. However, the torsional stiffness of the current connecting frame is relatively small, which makes the connecting frame prone to torsional deformation and breakage, and further makes the battery pack easily detached from the frame, resulting in low safety performance of the vehicle. Specifically, the current frame includes a parallel left longitudinal beam, a right longitudinal beam, and a plurality of cross beams connecting the left longitudinal beam and the right longitudinal beam. The battery pack is connected to the left longitudinal beam and / or the right longitudinal beam through a connecting frame, and the distance from the connecting frame to the two adjacent cross beams is equal, which makes the distance between the connecting frame and the two adjacent cross beams far, resulting in low torsional stiffness of the connecting frame. To this end, the utility model proposes a vehicle, which aims to improve the torsional stiffness of the connecting frame, thereby avoiding the connecting frame from breaking due to torsional deformation, and further making it difficult for the battery pack to detach from the frame, resulting in high safety performance of the vehicle.

[0037] Reference Figures 1 to 4In one embodiment of the utility model, the vehicle includes a frame 100, a battery pack 200 and a mounting bracket 300. The frame 100 includes a crossbeam 110 and a longitudinal beam connected to the crossbeam 110. The battery pack 200 is arranged 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 has a connecting end 410 connected to the longitudinal beam. The connecting end 410 is arranged close to a crossbeam 110 in the front-to-back direction. In this way, the distance between the connecting end 410 of the connecting frame 400 and the crossbeam 110 in the front-to-back direction is relatively close. The connecting frame 400 can use the crossbeam 110 to improve the torsional rigidity of the connecting frame 400, thereby preventing the connecting frame 400 from breaking due to torsional deformation, thereby making it difficult for the battery pack 200 to separate from the frame 100, so that the safety performance of the vehicle is higher.

[0038] Further, in one embodiment, in the front-to-back direction, the connection end 410 has a midpoint, the crossbeam 110 closest to the midpoint has a centerline extending in the left-right direction, the distance between the midpoint and the centerline in the front-to-back direction is A, and the length of the connection end 410 in the front-to-back direction is B, where A≤B. In this way, the distance between the connection end 410 of the connection frame 400 and the crossbeam 110 in the front-to-back direction is relatively close, and the connection frame 400 can use the crossbeam 110 to improve the torsional rigidity of the connection frame 400, thereby preventing the connection frame 400 from breaking due to torsional deformation, thereby making it difficult for the battery pack 200 to separate from the frame 100, so that the safety performance of the vehicle is higher.

[0039] Furthermore, in one embodiment, the midpoint is consistent with the centerline in the front-to-back direction. Thus, in the projection in the up-down direction, the projection of the center is located at the projection of the centerline. Thus, the distance between the connecting end 410 of the connecting frame 400 and the crossbeam 110 in the front-to-back direction is relatively close, and the connecting frame 400 can use the crossbeam 110 to improve the torsional rigidity of the connecting frame 400, thereby preventing the connecting frame 400 from breaking due to torsional deformation, thereby making it difficult for the battery pack 200 to detach from the frame 100, and improving the safety performance of the vehicle.

[0040] Optionally, in one embodiment, the mounting bracket 300 is disposed on one side of the battery pack 200 in the left-right direction. In this way, 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 frame 100 more stably.

[0041] Optionally, in one embodiment, two longitudinal beams are provided, and the two longitudinal beams include a left longitudinal beam 120 and a right longitudinal beam 130 respectively connected to the cross beam 110, and a plurality of mounting brackets 300 are provided, and the left longitudinal beam 120 is connected to the left side of the battery pack 200 through a mounting bracket 300, and the right longitudinal beam 130 is connected to the right side of the battery pack 200 through another mounting bracket 300. In this way, the left and right sides of the battery pack 200 are respectively provided with mounting brackets 300 to provide upward pulling force, so that the battery pack 200 is subjected to a more uniform force, and the battery pack 200 is connected to the frame 100 more stably.

[0042] Optionally, in one embodiment, the mounting bracket 300 includes an adapter frame 500 extending in the front-to-back direction, and a plurality of connecting frames 400 spaced apart in the front-to-back direction, and the plurality of connecting frames 400 are connected to the battery pack 200 through the adapter frame 500. It can be understood that the left and right sides of the battery pack 200 are respectively connected with the adapter frame 500. The adapter frame 500 is conducive to absorbing the installation tolerance of the battery pack 200 and the plurality of connecting frames 400, so as to facilitate the connection of the battery pack 200 with the plurality of connecting frames 400.

[0043] There are many structural forms of the adapter frame 500, please refer to Figure 5 and 6 Optionally, in one embodiment, the adapter frame 500 includes an adapter plate 510, and the adapter plate 510 is bent to have a reinforcement groove 511, and the reinforcement groove 511 includes a groove bottom wall 512 connected to the battery pack 200 and a first groove side wall 513 connected to the connecting frame 400. In this way, the shape of the adapter plate 510 itself is used to improve the structural strength of the adapter plate 510, and the weight of the adapter plate 510 will not be increased. However, the present design is not limited to this. In other embodiments, the adapter frame 500 can also be other structural forms as long as it has a high structural strength.

[0044] Optionally, in one embodiment, the reinforcement groove 511 is provided below the connecting frame 400. In this way, the groove bottom wall 512 is located below the first groove side wall 513. For the mounting bracket 300 having a preset length in the up and down direction, the length of the connecting frame 400 can be made shorter. Since the number of connecting frames 400 is large, it is beneficial to reduce the material used for the connecting frame 400 and reduce the replacement cost of the connecting frame 400. It should be noted that the preset length enables the battery pack 200 to have a safe distance from the ground. However, the present design is not limited to this. In other embodiments, the groove bottom wall 512 is located above the first groove side wall 513.

[0045] Refer to Figures 7 to 9Optionally, in one embodiment, a reinforcement member 600 is provided in the reinforcement groove 511, the mounting bracket 300 further includes a first fastener 810 penetrating the connecting frame 400, the adapter plate 510, and the reinforcement member 600, and the mounting bracket 300 further includes a second fastener 820 penetrating the reinforcement member 600, the adapter plate 510, and the battery pack 200. In this way, the reinforcement member 600 not only improves the strength of the connection between the adapter plate 510 and the connecting frame 400, but also improves the strength of the connection between the adapter plate 510 and the battery pack 200. The first fastener 810 and the second fastener 820 may be configured as, but not limited to, screws and other components.

[0046] Optionally, in one embodiment, the reinforcement member 600 includes a first reinforcement plate 610 parallel to the first groove side wall 513, a second reinforcement plate 620 parallel to the groove bottom wall 512, and a third reinforcement plate 630 whose normal direction is parallel to the extension direction of the reinforcement groove 511, the first reinforcement plate 610 is provided on the first groove side wall 513, the second reinforcement plate 620 is provided on the groove bottom wall 512, and the third reinforcement plate 630 connects the first reinforcement plate 610 and the second reinforcement plate 620. The first fastener 810 is provided through the connecting frame 400, the first groove side wall 513 and the first reinforcement plate 610 to connect the connecting frame 400 and the adapter frame 500, and the second fastener 820 is provided through the second reinforcement plate 620, the groove bottom wall 512 and the battery pack 200 to connect the adapter frame 500 and the battery pack 200. Further, in one embodiment, a plurality of third reinforcement plates 630 are provided in parallel along the extension direction of the reinforcement groove 511. However, the present design is not limited thereto, and in other embodiments, the reinforcement member 600 may also be in other structural forms, as long as it can improve the connection strength between the connecting frame 400 and the adapter frame 500 and the connection strength between the adapter frame 500 and the battery pack 200 .

[0047] Optionally, in one embodiment, the adapter frame 500 is provided with a first positioning hole 710 or a first auxiliary positioning hole passing through the first reinforcement plate 610 and the groove bottom wall 512, and the first positioning hole 710 or the first auxiliary positioning hole is used for the connecting frame 400 to be connected via a first positioning pin. The adapter frame 500 is also provided with a second positioning hole 720 or a second auxiliary positioning hole passing through the second reinforcement plate 620 and the groove side wall, and the second positioning hole 720 or the second auxiliary positioning hole is used for the battery pack 200 to be connected via a second positioning pin.

[0048] Optionally, in one embodiment, the adapter plate 510 is provided with a weight-reducing hole 514 to reduce the weight of the adapter plate 510 , which is beneficial to lightweighting of the vehicle.

[0049] Optionally, in one embodiment, the adapter frame 500 and the reinforcement member 600 are connected together by welding. However, the present design is not limited thereto, and in other embodiments, the adapter frame 500 and the reinforcement member 600 are detachably connected.

[0050] Optionally, in one embodiment, the battery pack 200 and the frame 100 are spaced apart in the vertical direction. In this way, the frequency of friction between the battery pack 200 and the frame 100 when the vehicle is running can be reduced, thereby extending the service life of the battery pack 200.

[0051] Optionally, in one embodiment, in the vertical direction, the spacing between the battery pack 200 and the frame 100 ranges from 10 mm to 20 mm. When the spacing is small, the battery pack 200 is easily worn. When the spacing is large, in order to ensure that the battery pack 200 has a safe distance from the ground, the battery pack 200 will be thinner, resulting in a smaller capacity of the battery pack 200. Therefore, when the spacing between the battery pack 200 and the frame 100 in the vertical direction ranges from 10 mm to 20 mm, the battery pack 200 is not easily worn, the service life of the battery pack 200 is longer, and the capacity of the battery pack 200 is larger.

[0052] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
