DETAILED DESCRIPTION

[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-5 As shown, a vehicle-mounted start-stop stabilizer structure includes a bottom shell 1 and a top cover 2. The upper end of the bottom shell 1 is open, and the interior of the bottom shell 1 is provided with a plurality of fixing columns 3 with threaded holes. It also includes a circuit board module 4. The circuit board module 4 is provided with a limiting hole 5 for the fixing column 3 to pass through. The circuit board module 4 has a connecting terminal 1 6 and a connecting terminal 2 7. The outer side of the bottom shell 1 is provided with a fence 1 8 and a fence 2 9. The fence 1 8 and the fence 2 9 are used to protect the connecting terminal 1 6 and the connecting terminal 2 7 respectively. The outer side of the bottom shell 1 is symmetrically provided with side panels 10, and the side panels 10 are provided with waist holes 11. The upper surface of the top cover 2 is provided with grooves 19 that match the position and number of the fixing columns 3, and the bottom of the grooves 19 is provided with through holes. It also includes screws 12 for fixing the top cover 2 to the fixing columns 3. A sink 13 is provided in the middle position of the top cover 2, and heat sinks 14 are evenly arranged inside the sink 13.

[0019] When installing the circuit board module 4, first align the limiting holes 5 on the circuit board module 4 with the fixing posts 3 at the bottom of the bottom shell 1, place the circuit board module 4 on the bottom of the bottom shell 1, and then place the top cover 2 on the bottom shell 1. At this time, the groove 19 on the top cover 2 passes through the fixing post 3 through the through hole, so that the lower end of the groove 19 abuts against the circuit board module 4. When the lower end of the groove 19 abuts against the circuit board module 4, the upper end of the fixing post 3 is located in the through hole of the groove 19, and then the screw 12 is screwed into the fixing post 3, and the groove 19 is fixed to the fixing post 3 by the screw 12, and then the top cover 2 is fixed to the bottom shell 1, completing the installation of the circuit board module 4 and the connection between the bottom shell 1 and the top cover 2. When repairing the circuit board module 4, the fixation of the top cover 2 and the circuit board module 4 can be released at the same time by rotating the screw 12 in the opposite direction, thereby improving the disassembly and assembly efficiency of the circuit board module 4.

[0020] The provision of the groove 19 and the sink 13 can not only increase the ability of the top cover 2 to resist deformation, but also increase the surface area of ​​the top cover 2, thereby accelerating heat transfer and discharging the heat generated by the circuit board module 4 through the bottom shell 1 and the top cover 2. In addition, the provision of the heat sink 14 can further improve the heat exchange capacity of the top cover 2. The top cover 2, the bottom shell 1 and the heat sink 14 can be made of metal aluminum to increase the heat dissipation capacity.

[0021] Furthermore, a compressible gasket 15 is provided at the bottom of the groove 19 , and the gasket 15 is used to protect the circuit board module 4 and prevent the circuit board module 4 from being damaged due to a large squeezing force between the groove 19 and the circuit board module 4 .

[0022] Furthermore, an annular inner retaining ring 16 is provided at the upper end of the bottom shell 1, and an annular groove 17 is provided at the lower end of the top cover 2 for accommodating the inner retaining ring 16. By providing the inner retaining ring 16 and the annular groove 17, the connection stability between the top cover 2 and the bottom shell 1 can be improved, and the edge of the top cover 2 can be prevented from deforming toward the inside of the bottom shell 1. At the same time, the connection sealing between the top cover 2 and the bottom shell 1 can also be increased to reduce the entry of dust and the like.

[0023] Furthermore, the four corners of the lower end of the bottom shell 1 are respectively concave, which can increase the ability of the bottom shell 1 to resist pressure and deformation, and improve the stability of the bottom shell 1.

[0024] Furthermore, a reinforcing plate 18 is provided between the side plate 10 and the bottom shell 1 to improve the connection stability between the side plate 10 and the bottom shell 1 .

[0025] This type of voltage stabilizer structure can increase the surface area of ​​the top cover 2, which is beneficial to absorbing the heat generated by the voltage stabilizer during operation, and realizes heat exchange with the external air through the top cover 2, thereby improving the heat dissipation effect of the voltage stabilizer, which is beneficial to improving the stability of the voltage stabilizer during operation. In addition, while increasing the surface area of ​​the top cover 2, it can also increase its strength, making it have better resistance to deformation, which is beneficial to protecting the electronic components in the voltage stabilizer and has a good use effect.
