The two sides of the power regulator lack effective buffering and anti-collision measures, which in turn causes damage to the outer shell. At the same time, the power regulator also lacks effective temperature detection inside and is easily damaged when the temperature is too high. Therefore, it does not meet the existing needs. In this regard, we propose a power regulator with a protective structure. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model provides buffer cavities at the four corners on both sides of the main body of the power regulator. When an external object accidentally collides with it during installation or transportation, the impacting object will first contact the buffer plate, which is an ultra-high molecular weight polyethylene plate, and has a good buffering effect, which can buffer the impact. Subsequently, the impact will be transmitted to the movable plate through the rubber column, and the movable plate will slide on the guide rod. The friction force generated by the sliding can consume the energy of the vibration input and squeeze the buffer spring at the same time. The buffer plate can be buffered by the elastic action of the buffer spring, thereby further improving the buffering effect, reducing the impact caused by the impact, avoiding damage to the main body of the power regulator, and improving the effect of external protection.

[0017] 2. The utility model is provided with a temperature sensor at the lower end of the top cover, through which the temperature of the internal components of the power regulator body can be detected. When the temperature is too high, the motor can be rotated by the microcontroller. The rotation of the motor will cause the threaded rod to drive the moving block to move the connecting rod into the transmission cavity, thereby separating the dynamic energized end from the static energized end. The opening and closing of the dynamic energized end and the static energized end are connected to the total power supply of the internal components of the power regulator body. Therefore, when the two are separated, the power will be cut off, thereby avoiding damage caused by excessive temperature and improving safety.

When heat is generated inside the power regulator body, the heat will be transferred to the heat dissipation fins.

[0028] It also includes a buffer cavity 15, which is opened at the four corners on both sides of the inside of the power regulator body 1. A movable plate 18 is provided inside the buffer cavity 15, and a rubber column 19 is bonded and fixed to the outer side of the movable plate 18. One end of the rubber column 19 extends to the outside of the buffer cavity 15, and the rubber column 19 is slidably matched with the buffer cavity 15. Buffer plates 14 are provided on both sides of the power regulator body 1, and the buffer plates 14 are bonded and fixed to one end of the rubber column 19 located outside the buffer cavity 15.

[0029] When in use, the temperature inside the power regulator body 1 can be detected by the temperature sensor 13, and the detected temperature signal can be transmitted to the microcontroller 3 for processing. When the temperature is too high, the microcontroller 3 will start the micromotor 5 to make the threaded rod 6 drive the moving block 8 to rotate, and the moving block 8 will drive the connecting rod 10 to separate the dynamic power-on end 11 from the static power-on end 12. Since the opening and closing of the dynamic power-on end 11 and the static power-on end 12 are connected to the total power supply of the components inside the power regulator body 1, the separation of the two will cut off the power to the components, avoiding damage caused by excessive temperature and improving safety.

[0030] See also Figure 1 and Figure 5 A temperature sensor 13 is installed at the lower end of the top cover 2, a micromotor 5 is arranged on one side of the upper end of the transmission cavity 4, and the output end of the micromotor 5 is connected to the threaded rod 6 through a coupling transmission, a microcontroller 3 is arranged on one side of the top cover 2, and the microcontroller 3 is electrically connected to the temperature sensor 13 and the micromotor 5, and the temperature sensor 13 can detect the temperature inside the power regulator body 1 to achieve the monitoring function;

[0036] Working principle: During use, if the power regulator body 1 is accidentally hit during transportation or installation, the impacting object will first contact the buffer plate 14. The buffer plate 14 can avoid scratches on the power regulator body 1. The buffer plate 14 can buffer the impact to a certain extent, and then the impact can be transmitted to the moving plate 18 through the rubber column 19, so that the moving plate 18 slides on the guide rod 16. The sliding of the moving plate 18 will cause the compression of the buffer spring 17, so that the moving plate 18 can be buffered by the elastic action of the buffer spring 17, thereby achieving buffering of the buffer plate 14, reducing the damage to the power regulator body 1 caused by the impact, and improving the protection effect. During daily use, the internal components of the power regulator body 1 will generate heat, and the temperature inside the power regulator body 1 can be detected by the temperature sensor 13. The temperature sensor 13 can detect The measured temperature signal is transmitted to the microcontroller 3 for processing. When the temperature is too high, the microcontroller 3 will start the micromotor 5. The micromotor 5 will rotate the threaded rod 6 through the coupling. The threaded rod 6 will drive the moving block 8 to rotate synchronously. Since the moving block 8 and the limit rod 7 slide together, the moving block 8 will be axially limited. The rotation of the moving block 8 will be converted into a horizontal linear movement, so that the moving block 8 drives the connecting rod 10 to move into the transmission cavity 4. When the connecting rod 10 moves, it will drive the dynamic energized end 11 to separate from the static energized end 12. Since the opening and closing of the dynamic energized end 11 and the static energized end 12 are connected to the total power supply of the components inside the power regulator body 1, the separation of the two will cut off the power to the components, avoiding damage caused by excessive temperature, improving safety, and the heat dissipation effect during use can be increased through the heat dissipation fins 20 on both sides, improving the cooling effect, and having good practicality.
