Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a vehicle battery rack and a vehicle. Background Technology

[0002] With the development of new energy vehicle technology, fuel cells and power batteries, as core components of the power system, have crucial structural designs.

[0003] Currently, the common design method is to fix the fuel cell frame and the power battery frame separately to the cantilever beam structure of the vehicle frame. In developing this invention, the inventors discovered the following problems in the existing technology: There are errors in the side angles of the incoming main beam of the vehicle frame, and there are also errors in the cantilever beams assembled on the main beam. If the installation dimensions of a single frame of the split-structure fuel cell frame and power battery frame are deviated, it will stretch the cantilever beam structure, leading to a larger deviation in the main beam dimensions, making it impossible to install the other frame. Accumulated errors can easily affect the installation accuracy of the battery frame. Furthermore, during installation, occasional misalignment of the mounting points requires enlarging the mounting holes, which not only increases the assembly difficulty but may also damage the structural integrity. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle battery rack and vehicle, which aims to improve the problem of poor installation accuracy and inconvenience of existing battery racks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vehicle battery rack includes a first frame for mounting a fuel cell and a second frame for mounting a power battery, as well as a plurality of connecting beams connecting the first frame and the second frame;

[0007] At least one first mounting sub-beam connected to the vehicle frame is provided on the inner side frame of the first frame, and multiple first locking brackets for connecting to the vehicle frame are provided on the top surface of the two ends and / or the middle of the first frame.

[0008] The inner side frame of the second frame is provided with at least one second mounting sub-beam connected to the vehicle frame, and the top surface of the two ends and / or the middle of the second frame is provided with a plurality of second locking brackets for connecting to the vehicle frame.

[0009] Preferably, the top surface of the first frame is provided with a plurality of locking parts for connecting to the vehicle frame.

[0010] Preferably, the first frame is provided with a first placement space and a second placement space for placing the fuel cell.

[0012] A heat insulation sealing plate is provided between the second installation space and the third installation space.

[0013] Preferably, it also includes a first reinforcing beam detachably disposed on a plurality of first mounting sub-beams, and a second reinforcing beam detachably disposed on a plurality of second mounting sub-beams;

[0014] The first reinforcing beam is provided with a first fixing beam that can be detachably installed with the first locking frame, and the second reinforcing beam is provided with a second fixing beam that can be detachably installed with the second locking frame.

[0015] Preferably, the first fixed beam and the first reinforcing beam are integrated, and the second fixed beam and the second reinforcing beam are integrated.

[0016] Preferably, a first locking member is provided between the first fixed beam and the first locking frame; a second locking member is provided between the second fixed beam and the second locking frame.

[0017] Preferably, at least one reinforcing beam is provided on the outer edge of the second frame.

[0018] Preferably, the connecting beam is laterally connected between the bottom of the first frame and the second frame.

[0019] A vehicle is also provided, including the aforementioned vehicle battery rack.

[0020] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0021] 1. In this utility model, the fuel cell frame and the power battery frame are integrated into a single design.

[0022] 2. In this utility model, the integrated structure, except for the installation points and some technical requirements, is formed by welding. The dimensions of the installation points can be better controlled by tooling, thereby reducing errors caused by the production process and improving assembly accuracy and structural reliability.

[0023] 3. The integrated battery rack structure in this utility model can reduce the stretching of the outward beams. Compared with the split battery rack structure, it can improve the installation accuracy and avoid situations where installation is impossible. Attached Figure Description

[0041] Example 1

[0042] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a vehicle battery rack, including a first frame 10 for mounting a fuel cell and a second frame 11 for mounting a power battery, as well as a plurality of connecting beams 12 connecting the first frame 10 and the second frame 11; at least one first mounting sub-beam 101 connected to the vehicle frame is provided on the inner side frame of the first frame 10, and a plurality of first locking brackets 102 for connecting to the vehicle frame are provided on the top surface of both ends and / or the middle of the first frame 10; at least one second mounting sub-beam 111 connected to the vehicle frame is provided on the inner side frame of the second frame 11, and a plurality of second locking brackets 112 for connecting to the vehicle frame are provided on the top surface of both ends and / or the middle of the second frame 11.

[0043] Specifically, the first mounting sub-beam 101 of the first frame 10 is bolted to the first reinforcing beam 13 of the frame, and the first locking frame 102 is bolted to the first fixing beam 131 of the frame. The second mounting sub-beam 111 of the second frame 11 is bolted to the second reinforcing beam 14 of the frame, and the second locking frame 112 is bolted to the second fixing beam 141 of the frame. This structural design enhances the connection strength and stability between the battery rack and the frame.

[0044] In addition, multiple connecting beams 12 are laterally connected between the bottom of the first frame 10 and the second frame 11. The two ends of the connecting beams 12 are fixedly connected to the first frame 10 and the second frame 11 by bolts, and the multiple connecting beams 12 are arranged at intervals along the length direction of the first frame 10 and the second frame 11 to enhance the stability and load-bearing capacity of the overall structure of the battery rack and avoid structural deformation or damage due to weight.

[0045] Therefore, integrating the first frame 10 and the second frame 11 into a single structure reduces the overall weight and the number of locking points for connection to the vehicle frame compared to a separately fixed battery rack structure, thereby reducing assembly complexity. Furthermore, except for mounting points and some technically required points, the single-piece structure is formed by welding, allowing for better control of the mounting point dimensions through tooling. This reduces errors caused by manufacturing processes and improves assembly accuracy and structural reliability.

[0046] Compared to a split battery rack, where dimensional deviations in one battery rack can stretch the outer beam of the frame, leading to larger deviations in the frame's main beam dimensions and making it impossible to install the other battery rack, the integrated battery rack structure in this embodiment reduces stretching of the outer beam, thereby improving installation accuracy and preventing installation failures.

[0047] like Figure 3 As shown, in this embodiment, the top surface of the first frame 10 is provided with a plurality of locking parts 103 for connecting with the vehicle frame. By providing locking parts 103 for locking with the vehicle frame on the side of the first frame 10, the fuel cell can be lifted and pushed horizontally into the first frame 10 from the side. The workshop can choose to lift or install from the side, improving the convenience of operation.

[0048] like Figure 3 As shown, in this embodiment, the first frame 10 is provided with a first placement space 104 and a second placement space 105 for placing fuel cells. The first placement space 104 is used to install a 245kW fuel cell, and the second placement space 105 is used to install a 110kW fuel cell.

[0049] like Figure 4 As shown, in this embodiment, the second frame 11 is provided with a first mounting space 113, a second mounting space 114, and a third mounting space 115. The first mounting space 113 is used to install two sets of power batteries, the second mounting space 114 is used to install an air pump, and the third mounting space 115 is used to install high-voltage components.

[0050] Furthermore, a heat insulation plate 117 is provided between the second installation space 114 and the third installation space 115. The heat insulation plate 117 can act as a physical barrier to prevent heat from being transferred to the high-voltage component area. For example, it can block heat radiation and convection through low thermal conductivity materials to ensure the stable working performance of the high-voltage component.

[0051] In addition, several weight-reducing holes (not shown in the figure) and plug welding holes (not shown in the figure) are provided on the first frame 10 and the second frame 11. By providing weight-reducing holes, the amount of metal material used can be reduced and the overall weight of the battery rack can be reduced; the plug welding holes achieve high-strength connection by filling with molten metal, thereby improving the overall connection strength and stability of the battery rack.

[0052] like Figure 2 As shown, this embodiment also includes a first reinforcing beam 13 detachably mounted on a plurality of first mounting sub-beams 101, and a second reinforcing beam 14 detachably mounted on a plurality of second mounting sub-beams 111; the first reinforcing beam 13 is provided with a first fixing beam 131 detachably mounted to the first locking frame 102, and the second reinforcing beam 14 is provided with a second fixing beam 141 detachably mounted to the second locking frame 112.

[0053] Specifically, the first mounting sub-beam 101 and the second mounting sub-beam 111 are respectively locked to the sides of the first reinforcing beam 13 and the second reinforcing beam 14, while the first locking bracket 102 and the second locking bracket 112 are respectively locked to the bottom of the first fixing beam 131 and the second fixing beam 141, ensuring the stability of the overall battery rack mounted on the vehicle frame. Furthermore, the first fixing beam 131 and the first reinforcing beam 13 are integrated, and the second fixing beam 141 and the second reinforcing beam 14 are also integrated.

[0054] In this embodiment, a first locking member (not shown in the figure) is provided between the first fixed beam 131 and the first locking frame 102; a second locking member (not shown in the figure) is provided between the second fixed beam 141 and the second locking frame 112. Specifically, the first locking member and the second locking member are bolts, which are used to detachably connect the first fixed beam 131 and the first locking frame 102, and to detachably connect the second fixed beam 141 and the second locking frame 112.

[0055] like Figure 4 As shown, in this embodiment, at least one reinforcing beam 116 is provided on the outer edge of the second frame 11. By providing the reinforcing beam 116, the structural strength and load-bearing capacity of the second frame 11 can be effectively improved, thereby ensuring that the second frame 11 can remain stable when subjected to large loads and preventing structural failure due to deformation or fatigue.

[0056] Example 2

[0057] A vehicle is also provided, including the vehicle battery rack described in Example 1. By designing an integrated vehicle battery rack, the assembly precision of the battery rack is effectively improved, the difficulty of installation operations is reduced, and assembly efficiency is increased.

[0058] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
