[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an L-shaped PCB adapter board, including a base 1 and a PCB adapter board body 2. The device is installed inside a vehicle via the base 1. A vertically arranged fixing post 14 is fixedly connected to the top of the base 1. The number of fixing posts 14 is set to multiple, and the multiple fixing posts 14 are symmetrically arranged on the top of the base 1. The PCB adapter board body 2 is detachably installed on the top of the fixing post 14 by screws 15. By removing the screws 15, the PCB adapter board body 2 can be removed from the top of the base 1 for maintenance. A protective mechanism is provided on the top of the base 1, and a buffer mechanism is provided on the bottom of the base 1.

[0033] Reference Figure 3 - Figure 6The buffer mechanism includes a sleeve 3, which is fixedly installed on the inner wall of the bottom of the base 1. A through hole 4 is provided at the top of the sleeve 3. A cylinder 6 is rotatably connected to the inner wall of the sleeve 3. A through hole 7 is provided on the right side of the cylinder 6. The diameters of the through holes 4 and 7 are equal. Sealing rings 5 ​​are fixedly connected to the inner walls of both through holes 4 and 7 to increase the airtightness between the sleeve 3 and the cylinder 6. An inflation pipe 8 for filling the base 1 with inert gas is fixedly connected to the right side of the cylinder 6. A positioning rod 9 is slidably connected to the inner wall of the cylinder 6. The top of the positioning rod 9 is connected to the cylinder via a spring 10. The inner wall of cylinder 6 is elastically connected. A spring 10 is set to apply a spring force to the positioning rod 9 away from the center of cylinder 6. The inner wall of sleeve 3 is provided with a positioning groove 11 that matches the positioning rod 9. The inside of cylinder 6 is provided with cavity 12. Inert gas is filled into cavity 12 through air tube 8. The top of base 1 is provided with airbag 13 with good elasticity. Airbag 13 has a rebound effect. The gas inside airbag 13 plays a damping rebound effect. The bottom of PCB adapter board body 2 contacts the top of airbag 13. The inflated airbag 13 supports and buffers PCB adapter board body 2.

[0034] Reference Figure 5 The number of through holes 4 is set to be multiple, and the multiple through holes 4 are arranged in a straight line at equal intervals on the surface of the sleeve 3. The number of through holes 7 is set to be multiple, and the number of through holes 4 and through holes 7 are opposite. The positions of the multiple through holes 7 and the multiple through holes 4 correspond one-to-one. The through holes 4 and through holes 7 are not initially on a straight line. When the through holes 4 and through holes 7 are on a straight line, the interior of the base 1 and the interior of the cavity 12 are connected. At this time, inert gas can be added to the interior of the base 1 through the air inflator 8, so that the airbag 13 expands.

[0035] Reference Figure 4 - Figure 6 The bottom of the positioning rod 9 is provided with an arc-shaped surface. The positioning rod 9 is located on the left side of the cylinder 6. The positioning rod 9 and the second through hole 7 are on the same plane. The number of positioning grooves 11 is set to two sets. The two sets of positioning grooves 11 are arranged in a ring and are set on the inner wall of the sleeve 3 at a distance of 90 degrees. The positioning rod 9 is initially inserted into the positioning groove 11 located on the left side. When the first through hole 4 and the second through hole 7 are in a straight line, the positioning rod 9 is inserted into the positioning groove 11 located at the bottom. The inside of the airbag 13 is connected to the inside of the base 1. The inside of the base 1 is connected to the inside of the cavity 12 when the first through hole 4 and the second through hole 7 are in a straight line. By rotating the cylinder 6 counterclockwise by 90 degrees, the inside of the base 1 and the inside of the cavity 12 are connected. Then, inert gas can be added to the inside of the base 1 through the inflation tube 8 to maintain a reasonable air pressure inside the base 1 and ensure the support and cushioning effect.

[0036] Reference Figure 1 - Figure 3The protective mechanism includes a protective cover 16 to prevent external objects from impacting the PCB adapter board body 2 inside the base 1, thereby reducing the possibility of damage to the PCB adapter board body 2. The protective cover 16 is detachably installed on the top of the base 1 by fastening bolts 17. By removing the fastening bolts 17, the PCB adapter board body 2 on the base 1 can be maintained. The protective mechanism also includes ventilation slots 18 for ventilation, which facilitates heat dissipation of the PCB adapter board body 2. The number of ventilation slots 18 is set to multiple, and the multiple ventilation slots 18 are evenly spaced on the surface of the protective cover 16. The protective mechanism also includes a wire bracket 20. The back of the protective cover 16 is provided with a wire hole 19. The wire bracket 20 is fixedly installed on the top of the L-shaped PCB adapter board body 2, which facilitates the organization and storage of the wires on the PCB adapter board body 2 and improves neatness.

[0037] Working principle: During use, when the base 1 is impacted by an external object or when an electric vehicle brakes suddenly, the PCB adapter board body 2 will be subjected to vibration energy. When the PCB adapter board body 2 is displaced by the impact, it compresses the airbag 13, causing the airbag 13 to deform. This causes the pressure inside the airbag 13 to increase. The increased pressure further hinders the downward displacement of the PCB adapter board body 2, thus playing a damping role. At the same time, the deformed airbag 13 has a rebound force, which applies a reaction force to the PCB adapter board body 2, thus playing a rebound role. Through the cooperation of the airbag 13 and the gas inside the airbag 13, the PCB adapter board body 2 is buffered and decelerated, reducing the possibility of vibration energy causing damage to the PCB adapter board body 2.

[0038] When the airbag 13 needs to be replenished after prolonged use, rotate the cylinder 6 counterclockwise by 90 degrees so that the through hole 4 and through hole 7 are aligned. Then, inert gas is injected into the inflation tube 8 using an external tool, which causes the air pressure inside the cavity 12, the base 1, and the airbag 13 to rise synchronously, keeping the pressure inside the airbag 13 within a reasonable range to ensure a buffering effect. After inflation is complete, rotate the cylinder 6 in the opposite direction by 90 degrees to prevent gas leakage.

[0039] When the cylinder 6 rotates relative to the sleeve 3, the cylinder 6 will also drive the positioning rod 9 to rotate. When the positioning rod 9 rotates, the arc-shaped surface of the positioning rod 9 contacts the edge of the positioning groove 11, thereby causing the positioning rod 9 to overcome the elastic force of the spring 10 and move towards the center of the cylinder 6. When the positioning rod 9 rotates to the inside of the next positioning groove 11, the positioning rod 9 will re-enter the inside of the positioning groove 11 under the elastic force of the spring 10, thereby improving the stability of the cylinder 6 and ensuring that the cylinder 6 will not rotate during inflation, thus ensuring the stability of inflation.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
