It should be understood that the detailed implementation manners described herein are only for explaining and illustrating the present disclosure, and are not used to limit the present disclosure.

[0023] In the present disclosure, unless otherwise stated, the orientation terms "upper, lower", "top, bottom" are based on the structure of the relevant components themselves, or can also be based on the positional relationship between the relevant components during actual use and other components. For example: the bottom surface of the first connecting plate attached to the longitudinal beam of the vehicle frame, where the bottom surface refers to the surface facing the ground when the longitudinal beam is installed on the vehicle body; the second connecting plate parallel to the first connecting plate and located on the "lower side" of the first connecting plate, where the "lower side" here means that when the mounting bracket is installed between the battery pack and the vehicle frame, the second connecting plate is located on the side closer to the ground compared to the first connecting plate. The "vehicle width direction" used refers to the lateral direction of the vehicle, which is perpendicular to the front-rear direction of the vehicle. In the embodiments of the present disclosure, it is also perpendicular to the extension direction of the longitudinal beam.

[0024] In addition, in the present disclosure, the terms "first", "second", etc. are used to distinguish one element from another, and do not have sequence and importance. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0025] Refer to Figures 1 - 3, this disclosure exemplarily shows a vehicle, including a battery pack 100 and a vehicle frame, and further including a mounting bracket 300 for hoisting the battery pack 100 onto the vehicle frame. Here, "hoisting" refers to a state in which the battery pack 100 is hoisted onto the vehicle frame, and the force exerted by the battery pack 100 on the vehicle frame is a downward pulling force, and it is not required that the entire battery pack 100 must be located below the vehicle frame. The mounting bracket 300 includes a first connecting plate 310 attached to the bottom surface of the longitudinal beam 200 of the vehicle frame, a second connecting plate 320 parallel to the first connecting plate 310 and located below the first connecting plate 310, and a third connecting plate 330 connecting the first connecting plate 310 and the second connecting plate 320. The first connecting plate 310 is provided with a first connecting portion for connecting with the longitudinal beam 200, and the second connecting plate 320 is provided with a second connecting portion for connecting with the battery pack 100. This disclosure does not limit the specific forms of the first connecting portion and the second connecting portion. For example, it may include the mounting holes mentioned below. Or it may also be a threaded post welded to the first connecting plate 310 and the second connecting plate 320, and this threaded post is used to connect the corresponding connecting plate with the longitudinal beam 200.

[0026] It should be explained that for the aforementioned "second connecting plate 320 parallel to the first connecting plate 310 and located below the first connecting plate 310", the "below" here means that in the height direction, the second connecting plate 320 is located below the first connecting plate 310, and it is not required that their projections in the height direction must overlap, that is, their projections in the height direction can be offset or partially intersect.

[0027] This disclosure does not limit the connection method and connection position of the third connecting plate 330 with the first connecting plate 310 and the second connecting plate 320. For example, in some embodiments, the third connecting plate 330 can be respectively welded to the first connecting plate 310 and the second connecting plate 320, and its connection position can be the position near the end side of the first connecting plate 310 and the second connecting plate 320, or it can also be connected to the position near the middle of the first connecting plate 310 and the second connecting plate 320. In addition, in some other embodiments, the third connecting plate 330 and the first connecting plate 310 and the second connecting plate 320 can be integrally formed by bending, which will be specifically introduced below.

[0028] Refer to Figure 2 and Figure 3, in an embodiment of the present disclosure, the first connecting portion may include a plurality of first connecting holes 410, and a plurality of third connecting holes (not shown in the figure) corresponding to the plurality of first connecting holes 410 one by one may be provided at the bottom of the longitudinal beam 200. The second connecting portion may include a plurality of second connecting holes 420, and a plurality of fourth connecting holes (not shown in the figure) corresponding to the plurality of second connecting holes 420 one by one may be provided on the battery pack 100. With such a design, when it is necessary to install the battery pack 100 on the longitudinal beam 200, the first connecting holes 410 and the third connecting holes are made to correspond one by one, and then the mounting bracket 300 can be connected to the longitudinal beam 200 by sequentially passing a fastener (such as a bolt) through the first connecting holes 410 and the third connecting holes; similarly, the second connecting holes 420 and the fourth connecting holes are made to correspond one by one, and then the mounting bracket 300 can be connected to the battery pack 100 by sequentially passing a fastener (such as a bolt) through the second connecting holes 420 and the fourth connecting holes.

[0029] In Figure 3 the illustrated embodiment, the number of the first connecting holes 410 and the second connecting holes 420 may each be three. In addition, in some other embodiments, the number of the first connecting holes 410 and the second connecting holes 420 may each be two, five, etc. The present disclosure does not limit the types of the first connecting holes 410 and the second connecting holes 420, which may be threaded holes, smooth through holes, etc., and can be adaptively designed according to actual situations.

[0030] Referring to Figure 2 and Figure 3 , in an embodiment of the present disclosure, the number of the plurality of first connecting holes 410 and the plurality of second connecting holes 420 may be the same, and in the height direction, a corresponding set of the first connecting holes 410 and the second connecting holes 420 may be disposed opposite to each other. With such a design, the corresponding first connecting holes 410, second connecting holes 420, third connecting holes, and fourth connecting holes can all be disposed opposite to each other in the height direction. When installing, first install the battery pack 100 on the lifting device, stop the lifting device after lifting the battery pack 100 to a suitable height, and then a fastener (such as a fastening bolt) can be sequentially passed from bottom to top through the fourth connecting hole, the second connecting hole 420, the first connecting hole 410, and the third connecting hole, and the fastening bolt can be locked by a nut at one end of the longitudinal beam 200 to achieve the installation. The integral connection of the battery pack 100, the mounting bracket 300, and the longitudinal beam 200 can be achieved by one fastening bolt, the structure is stable and firm, and the assembly difficulty can be effectively reduced, the assembly parts can be streamlined, and the vehicle weight can be reduced.

[0031] Referring to Figure 1, in an embodiment of the present disclosure, a side wing portion 110 protruding in the vehicle width direction may be provided on the side of the battery pack 100. The second connecting plate 320 may be attached to the upper surface of the side wing portion 110, and the fourth connecting hole may be provided in the side wing portion 110. With such a design, by connecting the second connecting plate 320 to the side wing portion 110, the connection between the battery pack 100 and the second connecting plate 320 can be achieved. The present disclosure does not limit the side wing portion 110, which may be a side wing plate formed by the housing of the battery pack 100 itself. Or it may also be a frame sleeved on the housing of the battery pack 100. The present disclosure does not limit this, as long as its upper surface is parallel to the second connecting plate 320 and has a fourth connecting hole formed.

[0032] In an embodiment of the present disclosure, two ends of the third connecting plate 330 may be respectively connected to the ends of the first connecting plate 310 and the second connecting plate 320 on the same side. The first connecting plate 310, the second connecting plate 320, and the third connecting plate 330 may be integrally bent and formed from a sheet metal. Specifically, the mounting bracket 300 of the present disclosure can be obtained by bending a sheet metal material. With such a design, the processing technology is simple, the quality is easy to control, the after-sales spare parts are convenient, the sheet metal cost is low, and it is suitable for mass production. In addition, this integral structure does not require the complex connection structures in the prior art, is convenient and fast to install, and is beneficial to lightweight.

[0033] Referring to Figure 2 and Figure 3 , in order to improve the use strength of the mounting bracket 300, in an embodiment of the present disclosure, the mounting bracket 300 may further include a plurality of reinforcing plates 340 welded between the first connecting plate 310 and the second connecting plate 320. By providing the reinforcing plates 340, the compressive capacity of the mounting bracket 300 can be improved, and each reinforcing plate 340 can play the same connection role and tensile resistance role as the third connecting plate 330, avoiding deformation of the mounting bracket 300 due to the large tensile force of the battery pack 100 received by the mounting bracket 300.

[0034] Further, referring to Figure 2 and Figure 3 , in an embodiment of the present disclosure, the side end of the reinforcing plate 340 may be welded to the third connecting plate 330. By welding the reinforcing plate 340 to the third connecting plate 330, the use strength of the mounting bracket 300 can be further improved. It should be noted that the shape of the edge of the reinforcing plate 340 for connecting with the third connecting plate 330 is the same as the shape of the third connecting plate 330, so that the reinforcing plate 340 can be fully connected to the third connecting plate 330. For example, in the embodiments shown in Figure 2 and Figure 3 , the side edge of the reinforcing plate 340 may be configured to be the same bent shape as the third connecting plate 330.

[0035] The present disclosure does not limit the structure of the third connecting plate 330. For example, in the Figure 2 and Figure 3 illustrated embodiment, the third connecting plate 330 may include a vertical section 331 attached to the side wall of the battery pack 100 and an inclined section 332 connected between the vertical section 331 and the first connecting plate 310. The inclined section 332 may gradually extend toward the direction close to the battery pack 100 in the upward direction, that is, extend toward the central axis direction of the vehicle. With such a design, by providing the inclined section 332, an avoidance function can be achieved, avoiding interference between the entire third connecting plate 330 extending vertically upward and other components of the vehicle.

[0036] Referring to Figure 1 , in the embodiments of the present disclosure, the number of the mounting brackets 300 may be multiple, and the multiple mounting brackets 300 may be distributed at intervals between the battery pack 100 and the longitudinal beam 200. With such a design, compared with traditional large mounting brackets (extending along the vehicle length direction and having a length similar to the battery pack length), the multiple mounting brackets 300 are arranged at intervals, which is beneficial to achieving lightweight, reducing the energy consumption of the whole vehicle, increasing the cruising range of the whole vehicle, and the multiple mounting brackets 300 can be independently installed and disassembled, with convenient operation.

[0037] Referring to Figure 1 , in the embodiments of the present disclosure, at least some of the multiple mounting brackets 300 are configured to have the same structure. With such a design, on the one hand, the mold opening cost can be reduced, the procurement or production difficulty can be reduced, and the installation process difficulty can be reduced (there is no need to distinguish different mounting brackets 300). On the other hand, there is better interchangeability and universality between the multiple mounting brackets 300.

[0038] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0039] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure does not separately describe various possible combination manners.

[0040] In addition, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
