[0076] like Figure 2 As shown, in one embodiment of the above power control module, a heat dissipation component for enhancing the structural strength of the upper cover is provided on the upper cover 1, and the heat dissipation component and the insulating support plate 32 are located on the same side for dissipating heat from the power control module.

[0077] In one embodiment of the above-mentioned power control module, the heat dissipation component includes a plurality of heat sinks 11, and the plurality of heat sinks 11 form an avoidance area 12 according to their own surrounding conditions. Specifically, the plurality of heat sinks 11 form an avoidance area 12a according to the moving position of the flip component 34 along the rotation angle of the rotating shaft 341, and the plurality of heat sinks 11 form an avoidance area 12b according to the external devices around themselves.

[0078] It should be noted that the plurality of heat sinks 11 form avoidance areas according to the movement positions of the components around them, the configurations of external devices or cables, and the like. Specifically, the positions and sizes of the heat sinks 11 can be reasonably set according to the positions of the devices around them and the shapes of the devices in different states to form avoidance areas.

[0079] like Figure 3 As shown, in one embodiment of the power control module, the insulating ring 31 is connected to the upper cover 1 by interference fit, and the function of the insulating ring 31 is to prevent the circuit board assembly component 2 from contacting the upper cover 1 when installing the battery cell, thereby causing a short circuit.

[0091] Specifically, Figure 7 As shown, in one embodiment of the present invention, the buckle part 343 of the flip assembly 34 is provided with two symmetrical buckle bodies 3431 on both sides of the bottom of the buckle part 343. The two buckle bodies 3431 are linked structures. When the flange structure 342 is pressed, the two buckle bodies 3431 are opened at the same time. The flange structure 342 has a large contact area. At the same time, the flange structure 342 is not perpendicular to the top surface of the flip assembly 34, which is convenient for pressing downward to open the buckle part 343. The space between the two buckle bodies 3431 is used for cable routing.

[0092] In addition, in order to further save space, a buckle-to-buckle structure is used between the flip assembly 34 and the insulating support body. This structure cannot limit the left and right directions, so a limiting portion is also provided inside the flip assembly 34.

[0099] like Fig.11 As shown, by pressing the flange structure 342 of the flip assembly 34, an upward and inward torque is transmitted to the buckle through the lever arm. Under the action of the torque, the buckle is separated from the buckle of the insulating support plate 32, thereby opening the buckle.

[0100] like Fig.12 As shown, the utility model also discloses a vehicle power supply device 100, including a shell 110, and a power battery located inside the shell 110, characterized in that it also includes a power control module as described in any of the above items, wherein the upper cover 1 of the power control module is connected to the shell.
