Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, and in particular to a supporting and mounting mechanism for a battery pack and a vehicle frame. Background Art

[0002] At present, new energy vehicles have attracted wide attention from all walks of life due to their excellent environmental performance. The requirements for new energy vehicles are also constantly increasing. As a new energy vehicle, electric vehicles are also developing in the direction of high safety, high energy ratio and light weight. The main factor that determines the mileage of electric vehicles is the power supply battery. Different specifications of power supply batteries can be selected for different models to meet driving requirements.

[0003] The power supply battery used in electric vehicles is generally a battery pack composed of multiple battery modules, that is, multiple battery modules are stacked up and down in the same box, and then the battery modules are connected and connected to the outside through a high-voltage box.

[0004] In this structure, the battery modules are close to each other, which will affect each other during operation, such as insufficient heat dissipation. In addition, if you want to increase or decrease the number of battery modules, you need to disassemble or replace the battery box with a larger capacity, which invisibly increases the complexity and cost of maintenance. In addition, since the high-voltage box is installed inside the battery box, its safety is also affected.

[0005] In order to solve the above technical problems, multiple battery packs can be connected to external high-voltage boxes respectively, thereby increasing the battery capacity of the vehicle and improving the power required by the vehicle.

[0006] However, there is no good solution for how to stably fix multiple battery packs and high-voltage boxes so that they can be firmly installed on new energy vehicles. As a result, when the vehicle is driving for a long time or on bumpy roads, the connection between the battery pack and the vehicle may easily become loose, which in turn causes the electrical connection between the battery packs and between the battery pack and the high-voltage box to become loose, resulting in the problem of the vehicle being unable to power itself normally.

[0007] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0008] The purpose of the utility model is to overcome the above-mentioned problems of the prior art and provide a supporting and mounting mechanism for a battery pack and a vehicle frame, which is used to solve the technical problem that when the vehicle is driving for a long time or on a bumpy road, the connection between the battery pack and the vehicle is easily loosened, which in turn causes the electrical connection between the battery packs and between the battery pack and the high-voltage box to loosen, resulting in the vehicle being unable to power supply normally.

[0009] The above objectives are achieved through the following technical solutions:

[0010] A support and mounting mechanism for a battery pack and a vehicle frame, comprising a battery pack supporting bracket connectable to the vehicle frame, the battery pack supporting bracket being provided with a longitudinal battery pack mounting position and a high-voltage box mounting position, a group of side edges of the battery pack being provided with battery pack side wings connectable to the longitudinal battery pack mounting position, and a group of side edges of the high-voltage box being provided with high-voltage box side wings connectable to the high-voltage box mounting position; the longitudinal battery pack mounting position comprising two battery pack mounting positions arranged one above the other; the high-voltage box mounting position being arranged adjacent to the battery pack mounting position located at the lowest layer.

[0011] Furthermore, the longitudinal battery pack installation position includes a group of symmetrically arranged frame plates, and two of the frame plates are connected by two groups of support plate groups respectively.

[0012] Furthermore, the support plate group includes a first support plate and a second support plate arranged up and down, the two first support plates can support the battery pack side wings of the battery pack located on the upper layer, and the two second support plates can support the battery pack side wings of the battery pack located on the lower layer.

[0013] Furthermore, a height between the first support plate and the second support plate is not less than a height of the battery pack.

[0014] Furthermore, the side wing of the battery pack is flush with the bottom edge of the battery pack.

[0015] Furthermore, a plurality of battery pack side wing connection holes are provided on the battery pack side wing, and are fixedly connected to the first support plate or the second support plate by screws.

[0016] Furthermore, the high-voltage box installation position includes a pair of high-voltage box support plates arranged on the outside of any of the frame plates.

[0017] Furthermore, a plurality of high-voltage box side wing connection holes are provided on the high-voltage box side wing, and are fixedly connected to the high-voltage box support plate by screws.

[0018] Furthermore, a high-voltage box edge extending outward is provided at the top edge port position of the high-voltage box, and a plurality of edge connection holes are provided on the high-voltage box edge, which is connected to the top of the frame plate by screws.

[0019] Furthermore, the high-voltage box support plate is flush with the bottom edge of the high-voltage box.

[0020] The utility model provides a support and installation mechanism for a battery pack and a vehicle frame. By fixing the battery pack support bracket to the vehicle frame, and providing a longitudinal battery pack installation position for installing the battery pack and a high-voltage box installation position for installing the high-voltage box on the battery pack support bracket, a plurality of battery packs and high-voltage boxes can be installed independently to meet the power supply requirements and ultimately provide the required power for the vehicle. This mechanism is not only simple in structure, but also can realize the longitudinal stacking and fixing of the battery pack and the external independent installation of the high-voltage box, and has a good connection effect. It can also facilitate the rapid assembly and disassembly of the high-voltage box and the battery pack, and can provide safe and stable protection for the normal power supply of the vehicle.

[0034] The longitudinal battery pack installation position 2 includes two battery pack installation positions 205 arranged one above the other, so as to realize the longitudinal stacking connection of each battery pack 4;

[0035] The high-voltage box installation position 3 is arranged adjacent to the battery pack installation position 205 located at the lowest layer, so that each battery pack 4 in the longitudinal direction is electrically connected to the same high-voltage box 5 through a cable.

[0036] The battery pack support bracket 1 in this embodiment can be fixed to the frame by welding or screw connection, and becomes one with the vehicle after fixation. The longitudinal battery pack mounting position 2 and high-voltage box mounting position 3 thereon are used to facilitate the portable installation or disassembly and maintenance of the battery pack 4 and the high-voltage box 5.

[0037] The battery pack support bracket 1 is made of corrosion-resistant and high-strength metal material, such as metal aluminum or stainless steel.

[0038] like Figure 3 and Figure 4 As shown, the longitudinal battery pack installation position 2 includes a group of symmetrically arranged frame plates 201, and the two frame plates 201 are connected by two groups of support plate groups 202 respectively, so that the longitudinal battery pack installation position 2 forms a rectangular or cubic shape frame.

[0039] It should be noted that, in this embodiment, the distance between the two frame plates 201 is not less than the length of the box body of the battery pack 4 .

[0047] As an optimization of the embodiment, a high-voltage box edge 503 extending outward is further provided at the top edge port position of the high-voltage box 5, and a plurality of edge connection holes 504 are opened on the high-voltage box edge 503, which is connected to the top of the frame plate 201 by screws.

[0048] It should be noted that, in this embodiment, the frame plate 201 connected to the edge 503 of the high-voltage box is provided with the high-voltage box support plate 301 on its outer side.

[0049] In this embodiment, the high-voltage box support plate 301 is flush with the bottom edge of the high-voltage box 5. This structure can ensure that after the high-voltage box 5 is connected to the two high-voltage box support plates 301, the bottom of the high-voltage box 5 is always located above the two high-voltage box support plates 301, avoiding interference with the components below the two high-voltage box support plates 301.
