[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] An automotive electronic control circuit board, such as Figure 1 As shown, it includes a mounting plate 1, the top of the mounting plate 1 is movably connected to a circuit board body 2, the top of the circuit board body 2 is fixedly connected to a plurality of capacitor elements 3, the side of the circuit board body 2 away from the capacitor elements 3 is fixedly connected to a junction box 4, the inner wall of the junction box 4 is fixedly connected to a support mechanism 5 for fixing the joint, both sides of the circuit board body 2 are movably connected to bolts 6, and the bottom of the circuit board body 2 is fixedly connected to a buffer mechanism 7 for protecting the circuit board body 2.

[0023] When in use, first, after the personnel fix the mounting plate 1, the circuit board body 2 can be installed on the outer wall of the mounting plate 1. As the personnel rotate the bolt 6, the circuit board body 2 will push the guide rod 701. At this time, the spring 2 704 will shrink under the action of the guide rod 701, thereby achieving a buffering effect. At the same time, the rubber plate 705 will reduce the friction between the circuit board and the circuit board. The buffer mechanism 7 can provide a certain buffer when the personnel install the circuit board between the circuit board and the mounting plate 1, thereby preventing the personnel from damaging the circuit board due to the large force during installation. At the same time, the buffer mechanism 7 can make a layer between the circuit board and the mounting plate 1, thereby improving the heat dissipation effect of the circuit board. After the circuit board is fixed, the external connector can be inserted into the inside of the junction box 4. As the connector is inserted, the top of the telescopic rod 502 will be squeezed. As the telescopic rod 502 shrinks, the connecting rods 504 on both sides will move outward synchronously. At the same time, the support plate 505 will support the inner wall of the external connector, thereby improving the stability between the connector and the junction box 4, preventing the connector from loosening during use of the equipment, thereby causing the capacitor element 3 on the circuit board to be short-circuited and damaged, thereby improving the safety of the equipment.

[0024] like Figure 3As shown, the support mechanism 5 includes a guide shell 501, a telescopic rod 502, a spring 503, a connecting rod 504 and a support plate 505. The telescopic rod 502 is fixedly connected to the inside of the guide shell 501, and the top of the telescopic rod 502 extends to the outside of the guide shell 501. One end of the connecting rod 504 is hinged to the outer wall of the telescopic rod 502, and the other end of the connecting rod 504 is hinged to the inner wall of the support plate 505. The spring 503 is fixedly connected to the outside of the telescopic rod 502, and the telescopic rod 502 is located on the opposite side of the spring 503. A through groove is provided on the outer wall of the guide shell 501, and the support plate 505 is movably connected to the inside of the through groove. The connecting rod 504 is provided with two groups symmetrical in upper and lower directions, and the guide shell 501 is provided with two groups symmetrical in left and right directions, and the guide shell 501 is fixedly connected to the inner wall of the junction box 4.

[0025] After the circuit board is fixed, the external connector can be inserted into the junction box 4. As the connector is inserted, the top of the telescopic rod 502 will be squeezed. As the telescopic rod 502 contracts, the connecting rods 504 on both sides will move outward synchronously. At the same time, the support plate 505 will support the inner wall of the external connector, thereby improving the stability between the connector and the junction box 4 and preventing the connector from loosening during the use of the equipment, which will cause the capacitor element 3 on the circuit board to short-circuit and be damaged, thereby improving the safety of the equipment.

[0026] like Figure 2-4 As shown, the buffer mechanism 7 includes a guide rod 701, a slider 702, a support rod 703, a second spring 704 and a rubber plate 705. The support rod 703 is fixedly connected to the inside of the rubber plate 705. The slider 702 is provided with two left-right symmetrical sliders, and the slider 702 is slidably connected to the outer wall of the support rod 703. The second spring 704 is fixedly connected to the opposite side of the slider 702. One end of the guide rod 701 is hinged to the bottom end of the circuit board body 2, and the other end of the guide rod 701 is hinged to the top end of the slider 702.

[0027] After the personnel have fixed the mounting plate 1, the circuit board body 2 can be installed on the outer wall of the mounting plate 1. As the personnel turn the bolt 6, the circuit board body 2 will push the guide rod 701. At this time, the spring 2 704 will shrink under the action of the guide rod 701, thereby achieving a buffering effect. At the same time, the rubber plate 705 will reduce the friction between the circuit board and the circuit board. The buffer mechanism 7 can provide a certain buffer when the personnel install the circuit board and the mounting plate 1, thereby preventing the circuit board from being damaged due to the strong force during the installation. At the same time, the buffer mechanism 7 can create a layer between the circuit board and the mounting plate 1, thereby improving the heat dissipation effect of the circuit board.

[0028] Here’s how it works:

[0029] First, after the personnel fix the mounting plate 1, the circuit board body 2 can be installed on the outer wall of the mounting plate 1. As the personnel turn the bolt 6, the circuit board body 2 will push the guide rod 701. At this time, the spring 2 704 will shrink under the action of the guide rod 701, thereby achieving a buffering effect. At the same time, the rubber plate 705 will reduce the friction between the circuit board and the circuit board. The buffer mechanism 7 can provide a certain buffer when the personnel install the circuit board and the mounting plate 1. After the circuit board is fixed, the external connector can be inserted into the interior of the junction box 4. As the connector is inserted, the top of the telescopic rod 502 will be squeezed. As the telescopic rod 502 shrinks, the connecting rods 504 on both sides will move outward synchronously. At the same time, the support plate 505 will support the inner wall of the external connector, thereby improving the stability between the connector and the junction box 4 and preventing the connector from loosening during the use of the equipment.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
