[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] Please see Figures 1-5 As shown, the purpose of this embodiment is to provide an easy-to-install vehicle circuit module, including a first circuit board 1, a second circuit board 2 fixedly connected to one side of the first circuit board 1, a plug 4 fixedly provided at one end of the first circuit board 1, and a plurality of sockets adapted to the plug 4 provided on the second circuit board 2, the sockets and the plug 4 being plugged in and engaged, one end of the plug 4 being plugged into the second circuit board 2, and a heat sink 12 for heat dissipation being fixedly provided on the second circuit board 2.

[0027] Positioning holes 3 are provided at the four corners of both the first circuit board 1 and the second circuit board 2. The positioning holes 3 are used to position and fix the circuit board inside the vehicle. The design of the positioning holes 3 enables the circuit board to be accurately positioned inside the vehicle, ensuring that the position of the circuit board is accurate.

[0028] At least one groove 13 is fixedly formed on the surface of the first circuit board 1 near its edge. In this embodiment, a groove 13 is also formed at an edge adjacent to the edge where the groove 13 is formed. The groove 13 faces a first direction, i.e., a vertical direction. The groove 13 has an arcuate groove segment 131 and an extended groove segment 132 connected to the arcuate groove segment 131. The extended groove segment 132 extends to the side wall of the first circuit board 1, forming a notch. For details, please refer to [link to relevant documentation]. Figure 4 The structure shown;

[0029] A locking ring 18 is provided at the arc groove section 131, and the inner diameter of the locking ring 18 is smaller than the inner diameter of the arc groove section 131. A locking space is formed between the groove wall of the arc groove section 131 and the locking ring 18. The locking ring 18 and the groove are integrally machined structures. A fixing block 6 is locked inside the locking ring 18. The side wall of the fixing block 6 is provided with several small protrusions to increase the friction between the fixing block 6 and the inner wall of the groove and prevent it from falling off.

[0030] The second circuit board 2 has a number of fixing rings 21 corresponding to each groove 13 fixedly installed on its side wall. The fixing rings 21 are inserted into the engagement space, and one side of the fixing block 6 is in contact with the fixing rings 21.

[0031] Since the size of the vehicle module installation position varies in different vehicles, the second circuit board 2 can be installed on one side of the first circuit board 1 or on the side adjacent to it, adapting to different installation positions and being easy to install. Since the fixing block 6 is platform-shaped, the protruding part can be engaged with the locking ring 18, while the platform part will fit with the fixing ring 21 set in the locking space.

[0032] A number of pins 41 extending outward from the second circuit board 2 are fixedly provided on one side of the plug 4. A pin slot 5 that mates with the pins 41 is provided on the side wall of the socket.

The pin slot 5 is provided with pins that are compatible with the pins 41, which are used to electrically connect the first circuit board 1 and the second circuit board 2 to ensure smooth signal transmission between the first circuit board 1 and the second circuit board 2. The pins 41 are inserted and fixed in the pin slot 5.

[0033] The first circuit board 1 includes at least a processor 11, and the heat sink 12 is fixedly mounted on the processor 11. Excessive temperature may cause the processor 11 to degrade or even be damaged, thereby causing the entire vehicle electronic system to malfunction. The heat sink 12 can significantly reduce the temperature of the processor 11, reduce system instability factors caused by high temperature, and improve the overall stability of the vehicle electronic system.

[0034] A number of connecting blocks 14 are fixedly provided on the side wall of the radiator 12. A screw hole 15 is provided through the connecting block 14, and a screw 16 is installed in the screw hole 15.

[0035] A plurality of limiting blocks 17 are fixedly disposed on the first circuit board 1. The limiting blocks 17 are located at the periphery of the processor 11. The limiting blocks 17 have through holes. One end of the screw 16 is threadedly connected to the through hole. The connecting block 14 is fixedly installed on the top of the limiting block 17 by the screw 16, thereby fixing the heat sink 12 on the processor 11.

[0036] In practical use, the fixing ring 21 is inserted into the engagement space, and the fixing block 6 is pressed and fixed in the engagement ring 18, thereby fixing the first circuit board 1 and the second circuit board 2. The pin 41 is inserted and fixed in the pin slot 5 to connect the signals of the two circuit boards. Then, the connecting block 14 is fixedly installed on the top of the limiting block 17 by the screw 16, thereby fixing the heat sink 12 on the top of the processor 11.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
