[0002] With the rapid development of new energy vehicle technology, the performance and safety of batteries as their core components have received widespread attention. During the operation of the battery, a certain amount of heat will be generated due to internal chemical reactions and current transmission. In order to ensure the normal operation of the battery and extend its service life, this heat must be effectively managed to avoid overheating of the battery. Therefore, the heat dissipation mechanism plays a vital role in the management of new energy batteries.

[0003] However, the existing heat dissipation mechanism for new energy battery management has some limitations in design. In particular, the size of the heat dissipation hole is usually fixed and cannot be adjusted according to the working state of the battery or external environmental conditions. Although this design method can meet the basic heat dissipation needs of the battery to a certain extent, it has many shortcomings in practical applications.

[0004] In winter, due to the low external ambient temperature, the battery often needs to be preheated to ensure its normal operation. However, since the size of the heat dissipation holes cannot be adjusted, the existing heat dissipation mechanism will still dissipate heat quickly in winter, resulting in poor battery preheating effect. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a heat dissipation mechanism for new energy battery management.

[0029] Example

[0030] like Figure 1 As shown, a heat dissipation mechanism for new energy battery management includes a heat dissipation frame 1, wherein the heat dissipation frame 1 is provided with a battery placement area 101 and a heat dissipation adjustment area 102; the battery placement area is used to accommodate batteries, and the heat dissipation adjustment area 102 is provided with an adjustment component 2. For reference, the battery placement area 101 is located in the central area of ​​the heat dissipation frame 1, and the battery placement area 101 is surrounded by the heat dissipation adjustment area 102. The battery placement area should have a groove or a fixing frame that matches the shape and size of the battery to ensure that the battery can be firmly placed therein. At the same time, the bottom and side of the battery placement area 101 can be designed with heat conductive materials, such as heat conductive sheets or heat conductive glue, so as to effectively conduct the heat generated by the battery to the heat dissipation adjustment area 102.

[0031] like Figure 2 and Figure 3 As shown, the adjustment assembly 2 includes a driving member 201, a screw rod 202, a screw rod nut 203, a slider 204 and a baffle plate 205. The driving member 201 is arranged in the heat dissipation adjustment area 102. One end of the screw rod 202 is connected to the driving member 201, and the other end of the screw rod 202 is rotatably connected to the side wall of the heat dissipation adjustment area 102. The screw rod nut 203 is threadedly connected to the screw rod 202, and the side wall of the screw rod nut 203 is connected to the slider 204, and the slider 204 is connected to the baffle plate 205; the driving member 201 can be a motor.

[0032] like Figure 4 As shown, a plurality of heat dissipation holes 103 are arranged at intervals on the side wall of the heat dissipation adjustment area 102, and the baffle plate 205 is arranged corresponding to the heat dissipation hole 103. In a possible embodiment, the baffle plate 205 is the same size as the heat dissipation hole 103, and the baffle plate 205 fits the heat dissipation hole. In a possible embodiment, the size of the heat dissipation hole 103 is the same as the interval area between the two heat dissipation holes 103. In a possible embodiment, the number of the lead screw nuts 203 is the same as the number of the baffle plates 205, the number of the sliders 204 is the same as the number of the baffle plates 205, the lead screw nuts 203 are arranged at intervals on the lead screw 202, and the stroke of the lead screw nut 203 on the lead screw 202 is the same as the length of the interval area between the two heat dissipation holes 103.

[0033] The shielding plate 205 has the same size as the heat dissipation hole 103, so that the shielding plate 205 can be completely attached to the heat dissipation hole 103. This ensures that when the shielding plate 205 moves to a specific position, it can completely cover the heat dissipation hole, thereby preventing the transfer of heat. At the same time, due to the consistency of size, the movement of the shielding plate 205 is also smoother, reducing the misalignment or jamming that may occur during the movement.

[0034] The screw nut 203 is arranged at intervals on the screw 202, and the stroke of the screw nut 203 on the screw 202 is the same as the length of the area between the two heat dissipation holes 103. This design ensures that the screw nut 203 can cover the entire heat dissipation hole area during movement, thereby achieving full adjustment of all heat dissipation holes. At the same time, since the stroke is the same as the length of the area between the heat dissipation holes, the problem of the screw nut exceeding the range or insufficient movement during movement is avoided.

[0035] When the driving member drives the lead screw to rotate, the lead screw nut performs linear motion on the lead screw. This linear motion is transmitted to the shielding plate through the slider, so that the shielding plate slides on the side wall of the heat dissipation adjustment area. Since the shielding plate is arranged corresponding to the heat dissipation hole and its size matches the heat dissipation hole, when the shielding plate moves, it can partially or completely cover the heat dissipation hole. When the shielding plate moves toward the heat dissipation hole, it will gradually cover the heat dissipation hole, thereby reducing the effective opening area of ​​the heat dissipation hole and reducing the heat dissipation efficiency. On the contrary, when the shielding plate moves away from the heat dissipation hole, it will gradually expose the heat dissipation hole, increase the effective opening area of ​​the heat dissipation hole, and improve the heat dissipation efficiency.

[0036] In this way, by controlling the movement of the shielding plate, the size of the heat dissipation hole can be precisely adjusted. In winter or when the battery needs to be preheated, by reducing the effective opening area of ​​the heat dissipation hole, the heat dissipation speed can be slowed down to ensure that the battery temperature does not drop too quickly. In other seasons or when the battery workload is heavy, by increasing the effective opening area of ​​the heat dissipation hole, the heat dissipation efficiency can be improved to keep the battery within a suitable operating temperature range.

[0037] In a possible implementation, Figure 5 As shown, the top and bottom of the heat dissipation adjustment area 102 are both provided with slide grooves 104 (one of them is shown in the figure, and it and the slide groove are not shown). The top and bottom of the shielding plate 205 are correspondingly arranged in the slide grooves 104. Specifically, the slide grooves 104 are pre-designed and fixed on the top and bottom of the heat dissipation adjustment area 102, and they form a guide rail structure for guiding the movement of the shielding plate 205. These slide grooves 104 usually have an opening that matches the width of the shielding plate 205 or is slightly larger than the width of the shielding plate to ensure that the shielding plate can slide smoothly inside it, and the top and bottom of the baffle 205 are designed with sliding parts corresponding to the slide grooves 104. These sliding parts can be raised sliders, slide rails or other shapes and structures that can adapt to the slide grooves. When the shielding plate 205 is installed in the heat dissipation adjustment area 102, its top and bottom sliding parts will be placed in the slide grooves 104.

[0038] Reference, such as Figure 6As shown, the shielding plate 205 includes a sliding portion 206 and a shielding portion 207, the sliding portion 206 is arranged on both sides of the shielding portion 207, the sliding portion 206 is arranged in the slide groove 104, and the shielding portion 207 is in contact with the heat dissipation hole 103. A sealing strip 208 is arranged on the side wall of the shielding portion 207. The sealing strip 208 is usually made of a material with good elasticity and sealing performance, such as rubber or silicone. When the shielding plate 205 moves to a certain position and the shielding portion 207 is in contact with the heat dissipation hole 103, the sealing strip 208 can fill the small gap between the shielding portion 207 and the heat dissipation hole 103 to prevent air or heat from leaking through these gaps. In this way, the effect of heat dissipation regulation can be enhanced and the heat dissipation efficiency can be improved.

[0039] The sliding part 206 is located at the top and bottom of the shielding plate 205, corresponding to the slide groove 104 of the heat dissipation adjustment area 102. In this way, when the driving member drives the slider to move, the slider is connected to the sliding part 206 of the shielding plate 205 through a connecting structure (such as a pin, a shaft, etc.), thereby driving the entire shielding plate 205 to slide in the slide groove 104. The shielding part 207 is the main part of the shielding plate 205, which corresponds to the heat dissipation hole 103. The size and shape of the shielding part 207 match the heat dissipation hole 103 to ensure that it can completely cover or expose the heat dissipation hole. Through the movement of the shielding plate 205, the shielding part 207 can change the opening size of the heat dissipation hole 103, thereby adjusting the heat dissipation efficiency. This design ensures the stability and reliability of the shielding plate 205 during the sliding process. Due to the matching design of the sliding part 206 and the slide groove 104, the shielding plate 205 can move smoothly in the heat dissipation adjustment area 102 without shaking or offset.

[0040] In a possible implementation, Figure 7 As shown, a limit strip 105 is provided on the side wall between the two heat dissipation holes 103. In a possible implementation, a sealing strip 208 is provided on the side wall of the shielding portion 207. A limit strip 105 is provided on the side wall between the two heat dissipation holes 103. The function of the limit strip 105 is to limit the movement range of the shielding plate 205 to prevent it from exceeding a predetermined area during the sliding process. By reasonably setting the position and size of the limit strip 105, it can be ensured that the shielding plate 205 can accurately stop at the specified position when moving to the maximum or minimum position, thereby realizing the complete opening or closing of the heat dissipation hole 103.

[0041] 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.
