[0028] Example

[0029] like Figure 1 As shown, a mounting frame for a new energy vehicle battery management system includes a frame 1, in which a horizontal clamping member 2, a vertical clamping member 3 and a rotating clamping assembly 4 are arranged. In a possible implementation, the rotating clamping assembly 4 is symmetrically arranged at the corners of the frame 1.

[0030] like Figure 2As shown, the horizontal clamping member 2 is connected to the inner wall of the frame 1, the vertical clamping member 3 is connected to the bottom inner wall of the frame 1, and the horizontal clamping member 2 and the vertical clamping member 3 are located in the same plane: the rotating clamping assembly 4 includes a driving member 41, a screw rod 42, a fixing member 43 and a screw nut 44, the output end of the driving member 41 is connected to the screw rod 42, the screw rod 42 is arranged inside the frame 1, the end of the screw rod 42 is rotatably connected to the inner wall of the frame 1, a plurality of fixing members 43 are provided, the fixing members 43 are arranged on the screw rod 42 at intervals, the screw nut 44 is threadedly connected to the screw rod 42, and the screw nut 44 is arranged between the two fixing members 43; the gap between the screw nut 44 and the fixing member 43 is used to accommodate the PCB board in the battery management system.

[0031] like Figure 2 and Figure 3 As shown, the horizontal side wall of the PCB board is arranged in the horizontal clamping member 2, and the vertical side wall of the PCB board is arranged in the vertical clamping member 3. The side wall of the PCB board is located in the gap between the screw nut 44 and the fixing member 43. The screw 42 runs through the corner of the PCB board. The screw nut 42 is driven to rotate by the driving member 41, and the screw nut 44 can move precisely along the screw 42. The screw nut 44 and the fixing member 43 further clamp the PCB. Since the screw nut 44 can move freely along the screw 42, the rotating clamping assembly can adapt to PCB boards of different thicknesses. Whether it is a thinner PCB board or a thicker PCB board, stable clamping can be achieved by adjusting the position of the screw nut 44. This design improves the versatility and flexibility of the mounting frame, making it applicable to a variety of different battery management systems.

[0032] In a possible implementation, Figure 4 As shown, the horizontal clamping member 2 includes a horizontal support member 201 and a first protruding member 202. The horizontal support member 201 is connected to the inner wall of the frame 1. The first protruding member 202 is connected to the horizontal support member 201. The first protruding member 202 is provided with a first card slot 203. The first card slot 203 is used to accommodate the PCB board in the battery management system. The inner wall of the first card slot 203 is provided with a first elastic positioning block 204 at intervals. The first elastic positioning block 204 can be fixed to the inner wall of the first card slot 203 by bonding, snapping, screw fixing, etc. During the fixing process, it is necessary to ensure that the position of the positioning block is accurate and firm to avoid loosening or falling off during subsequent use.

[0033] The first elastic positioning blocks 204 are symmetrically arranged on the inner walls on both sides of the first slot 203. They are symmetrically distributed on the inner walls on both sides of the slot to ensure that the PCB board can be evenly stressed when inserted, thereby achieving stable clamping.

[0034] For reference, the horizontal side wall of the PCB board in the battery management system can be placed in the first card slot 203, and the horizontal side wall of the PCB board is fixed by the first card slot 203. The first elastic positioning block 204 can be made of rubber or silicone material. The positioning block 204 made of rubber or silicone material has good elasticity and can provide appropriate buffering and positioning when the PCB board is placed in the card slot. The positioning block 204 made of rubber or silicone material has a certain friction coefficient, which helps prevent the PCB board from sliding during vibration.

[0035] In a possible implementation, Figure 5 As shown, the vertical clamping member 3 includes a vertical support member 301 and a second protruding member 302, wherein the vertical support member 301 is connected to the bottom inner wall of the frame 1, and the second protruding member 302 is connected to the vertical support member 301. The second protruding member 302 is provided with a second card slot 303, and the second card slot 303 is used to accommodate the PCB board in the battery management system. Second elastic positioning blocks 304 are arranged at intervals on the inner wall of the second card slot 303, and the second elastic positioning blocks 304 are symmetrically arranged on the inner wall of the second card slot 303. Second elastic positioning blocks 304 are also arranged at intervals on the inner wall of the second card slot 303. These elastic positioning blocks are symmetrically distributed on the inner wall of the card slot, and their functions are similar to those of the first elastic positioning blocks 204, which are to provide appropriate elasticity and friction so that the PCB board can be fixed in the card slot more tightly and stably. When the PCB board is placed in the card slot, these elastic positioning blocks will play their role to ensure that the PCB board can also be firmly clamped in the vertical direction.

[0036] It can be understood that the gap between the fixing member and the screw nut, the first slot 203 and the second slot 303 are respectively used to clamp different positions of the PCB board, so the gap between the fixing member and the screw nut, the width of the first slot 203 and the second slot 303 are similar.

[0037] like Figure 6 As shown, in a possible implementation manner, the side walls of the frame 1 are provided with heat dissipation holes 101. The side walls of the frame 1 are provided with electrical interfaces 102. The side walls of the frame 1 are provided with heat dissipation holes 101. This design is to ensure that the heat generated by the battery management system during operation can be dissipated in a timely and effective manner to prevent overheating from affecting system performance or causing potential safety risks.

[0038] An electrical interface 102 is also provided on the side wall of the frame 1. This design facilitates the connection between the battery management system and external devices or power supplies, making the entire system easier to integrate and use. The location and type of the electrical interface are selected according to actual needs, and may include a power interface, a signal interface, etc., to meet the connection requirements in different scenarios.

[0039] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
