[0035] Among them, an upper connecting block 3 is fixedly installed on the surface of the protective upper housing 1 away from the hinge 6, and a limiting groove 7 is provided on the left outer surface of the upper connecting block 3;

[0036] The lower protective housing 2 is fixedly provided with a lower connecting block 4 at a position corresponding to the upper connecting block 3, and the lower connecting block 4 is provided with a groove 8 at a position corresponding to the upper connecting block 3, and the upper connecting block 3 is slidably connected with the inner wall of the groove 8;

[0037] Wherein, a sealing device is arranged in the groove 8, and the sealing device is used to seal the protective upper shell 1 and the protective lower shell 2;

[0038] Among them, a sensor guide shaft 5 is arranged between the protective upper shell 1 and the protective lower shell 2, and circular grooves 14 are opened on the corresponding surfaces of the protective upper shell 1 and the protective lower shell 2. A buffer device is arranged in the circular groove 14, and the buffer device is used to provide buffering protection for the sensor guide shaft 5.

[0039] Further, the sealing device includes a first spring 10, the first spring 10 is fixedly connected to the bottom of the slide groove 9, and an end of the first spring 10 away from the bottom of the slide groove 9 is fixedly connected to an oblique connection block 11, and the oblique connection block 11 is slidably connected to the inner wall of the slide groove 9 and the inner wall of the groove 8;

[0040] Wherein, the oblique connection block 11 is slidably connected to the inner wall of the limiting groove 7;

[0041] Among them, the lower surface of the lower connecting block 4 corresponding to the slide groove 9 is provided with a straight slot 12, and the lower surface of the oblique connecting block 11 corresponding to the straight slot 12 is fixedly connected with a connecting rod 13, and the connecting rod 13 is slidably connected to the inner wall of the straight slot 12, and the protective upper shell 1 is moved toward the protective lower shell 2, and the upper connecting block 3 moves downward, squeezing the oblique connecting block 11 to move toward the inside of the slide groove 9, driving the first spring 10 to move backward, and the upper connecting block 3 continues to move downward. When the oblique connecting block 11 moves to the limiting groove 7, the first spring 10 drives the oblique connecting block 11 to bounce into the limiting groove 7, and the upper connecting block 3 moves downward. The protective upper shell 1 and the protective lower shell 2 are sealed. When the protective device needs to be opened, the oblique connecting block 11 is slid out of the limit groove 7 by pulling the sliding column 16. By providing a sealing device, the sealing device can effectively prevent pollutants such as dust, moisture, and chemicals from entering the interior of the sensor guide shaft 5. These pollutants may cause problems such as increased wear of the guide shaft, lubrication failure, or circuit short circuit, thereby affecting the normal operation of the sensor. Through good sealing, the cleanliness and dryness of the guide shaft and its surrounding components can be ensured, thereby extending its service life.

[0042] Furthermore, the buffer device includes a second spring 15, which is fixedly mounted at the center of the inner bottom end of the circular groove 14, and a sliding column 16 is fixedly connected to the inner bottom end of the second spring 15 away from the circular groove 14, and the sliding column 16 is slidably connected to the inner part of the circular groove 14;

[0043] Among them, a semicircular clamping plate 17 is fixedly installed at one end of the sliding column 16 away from the second spring 15. When the sensor guide shaft 5 is subjected to vibration or impact, the sensor guide shaft 5 squeezes the semicircular clamping plate 17 to move backward, and the semicircular clamping plate 17 drives the sliding column 16 to squeeze the second spring 15 backward. Since the second spring 15 wants to restore its original state, it squeezes the semicircular clamping plate 17 in the opposite direction to buffer and protect the sensor guide shaft 5. By providing a buffer device, the main function of the buffer device is to absorb and disperse the vibration and impact energy from the external environment. During the driving process of the car, especially in the case of bumpy roads or emergency braking, the sensor guide shaft 5 will be subjected to greater vibration and impact. The buffer device can effectively reduce the direct impact of these vibrations and impacts on the guide shaft, thereby protecting the guide shaft from damage and extending its service life;

[0044] Wherein, a lubrication device is provided on the semicircular clamping plate 17, and the lubrication device is used to lubricate the sensor guide shaft 5;

[0045] A limiting device for limiting the sliding of the sliding column 16 inside the circular groove 14 is disposed inside the circular groove 14 , and two rectangular grooves 20 are correspondingly formed on the inner wall of the circular groove 14 .

[0046] Furthermore, the limiting device includes two limiting blocks 19, both of which are slidably installed inside the rectangular groove 20, and the corresponding ends of the two limiting blocks 19 are fixedly connected to the two sides of the outer surface of the sliding column 16, and the two limiting blocks 19 are arranged at one end of the sliding column 16 close to the second spring 15.

[0047] Furthermore, the lubricating device includes three balls 18, which are all connected to the middle position of the outer surface of the semicircular clamping plate 17 in an annular rolling manner, and the contact surfaces of the three balls 18 and the semicircular clamping plate 17 are provided with lubricating liquid;

[0048] Among them, the outer surfaces of the three balls 18 are rollingly connected to the sensor guide shaft 5. The lubrication device provides necessary lubrication for the sensor guide shaft 5, reducing the friction coefficient of the guide shaft during operation. This not only reduces the wear on the guide shaft surface, extends the service life of the guide shaft, but also improves the overall operating efficiency of the sensor.

[0049] Furthermore, semicircular sealing gaskets 21 are fixedly installed at both ends of the protective upper shell 1 and the protective lower shell 2, and sealing strips 22 are fixedly installed on the corresponding surfaces of the protective upper shell 1 and the protective lower shell 2. The combination of the semicircular sealing gasket 21 and the sealing strip 22 can form a complete and tight sealing structure between the protective upper shell 1 and the protective lower shell 2. This design can effectively prevent external pollutants, such as dust, moisture, etc., from invading the interior of the protective device through any possible gaps, thereby ensuring the safe and stable operation of the sensor guide shaft and its related components.

[0050] Working principle: When using this device, move the protective upper shell 1 toward the protective lower shell 2, move the upper connecting block 3 downward, squeeze the oblique connecting block 11 to move toward the inside of the slide groove 9, drive the first spring 10 to move backward, and the upper connecting block 3 continues to move downward. When the oblique connecting block 11 moves to the limiting groove 7, the first spring 10 drives the oblique connecting block 11 to bounce into the limiting groove 7, and the protective upper shell 1 and the protective lower shell 2 are sealed. When it is necessary to open the protective device, the oblique connecting block 11 is slid out of the limiting groove 7 by pulling the sliding column 16. By providing a sealing device, the sealing device can effectively prevent pollutants such as dust, moisture, and chemicals from entering the interior of the sensor guide shaft 5. These pollutants may cause problems such as increased wear of the guide shaft, lubrication failure, or circuit short circuit, thereby affecting the normal operation of the sensor. Through good sealing, the cleanliness and dryness of the guide shaft and its surrounding components can be ensured, thereby extending their service life.

[0051] When the sensor guide shaft 5 is subjected to vibration or impact, the sensor guide shaft 5 squeezes the semicircular clamping plate 17 and moves backward, and the semicircular clamping plate 17 drives the sliding column 16 to squeeze the second spring 15 backward. Since the second spring 15 needs to return to its original state, it squeezes the semicircular clamping plate 17 in the opposite direction to provide buffering protection for the sensor guide shaft 5. A buffer device is provided, and its main function is to absorb and disperse vibration and impact energy from the external environment. During the driving of the car, especially on bumpy roads or in emergency braking, the sensor guide shaft 5 will be subjected to greater vibration and impact. The buffer device can effectively reduce the direct impact of these vibrations and impacts on the guide shaft, thereby protecting the guide shaft from damage and extending its service life.
