[0022] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0023] Referring to Figures 1-4 , an anti-detachment mechanism for an automotive pressure sensor, which includes a sensor body 1 installed on a vehicle body 2. An anti-detachment mechanism is provided between the sensor body 1 and the vehicle body 2. The anti-detachment mechanism includes a limit ring 3, a rotating ring 4, a fixing plate 5, a connecting arm 6, a fixing seat 7, a pushing part 8, a limit plate 9 and a spring 10. The limit ring 3 is fixed to the sensor body 1. The rotating ring 4 is rotatably installed in the middle of the limit ring 3. The fixing plate 5 is two and is oppositely fixed to the side of the rotating ring 4. The connecting arm 6 is installed at the bottom of the fixing plate 5. The fixing seat 7 is two and is fixed to the vehicle body 2. The two fixing seats 7 and the two connecting arms 6 are correspondingly arranged. The pushing part 8 is two and slides along two groups of sliding grooves 701 on the fixing seat 7 respectively. The limit plate 9 slides inside the fixing seat 7 and can extend into the limit groove 702 in the middle of the fixing seat 7. And the limit plate 9 is elastically connected to the fixing seat 7 through the spring 10;

[0024] During installation, push the pushing part 8 to retract the limit plate 9 into the fixing seat 7 so that the limit plate 9 does not extend into the limit groove 702. Align the bottom of the bottom plate 601 with the limit groove 702, and rotatably install the sensor body 1 on the vehicle body 2 until the sensor body 1 is completely rotatably installed on the vehicle body 2. At this time, the bottom plate 601 is attached to the bottom of the limit groove 702. Then release the restriction on the pushing part 8, and the elastic force of the spring 10 pushes the pushing part 8 back to its original position. The distance between the bottom surface of the limit plate 9 and the bottom surface of the limit groove 702 is adapted to the thickness of the bottom plate 601. When the bottom plate 601 is inserted into the limit groove 702, the bottom plate 601 can be stably restricted in the limit groove 702 through the limit plate 9. At this time, the limit plate 9 moves into the limit groove 702 and fits against the side wall of the connecting arm 6, restricting the bottom of the bottom plate 601 through the limit plate 9, that is, achieving the function of preventing the sensor body 1 from detaching;

[0025] When the sensor body 1 rotates onto the vehicle body 2, since the bottom plate 601 at the bottom of the connecting arm 6 remains corresponding to the limit groove 702, at this time the limit ring 3 rotates with the sensor body 1, while the rotating ring 4 and the fixing plate 5 also remain unchanged. According to the above settings, it is convenient to install the connecting arm 6 onto the fixing seat 7 through the bottom plate 601 at its bottom.

[0026] The width of the swivel ring 4 is adapted to the width of the middle annular groove of the limit ring 3, which enables the swivel ring 4 to rotate stably in the middle groove of the limit ring 3. The limit ring 3 is fixed on the sensor body 1. The swivel ring 4 can be rotated by pushing the fixing plate 5. After the connecting arm 6 at the bottom of the fixing plate 5 corresponds to the limit groove 702, the sensor body 1 can be rotationally installed on the vehicle body 2. During the downward movement of the sensor body 1, the bottom plate 601 can be gradually inserted into the limit groove 702. Until the sensor body 1 is completely installed, the bottom plate 601 also contacts the bottom of the limit groove 702 at this time, and subsequent limiting can be performed through the limit plate 9.

[0027] The connecting arm 6 is integrally composed of an elliptical cylinder and a bottom plate 601 with an elliptical structure. The size of the bottom plate 601 is larger than the size of the elliptical cylinder structure at its upper end, and the contour of the bottom plate 601 is adapted to the contour of the limit groove 702. The connecting arm 6 can be inserted into the limit groove 702 through the bottom plate 601, and the bottom plate 601 fits perfectly with the limit groove 702. Subsequently, the bottom plate 601 can be limited in the limit groove 702 through the limit plate 9.

[0028] The opposite sides of the two limit plates 9 on the fixed seat 7 are both provided with arc-shaped surfaces, which can be completely attached to the side edges of the elliptical cylinder structure of the connecting arm 6. After the bottom plate 601 is inserted into the limit groove 702, the limit plates 9 can extend and abut against both sides of the connecting arm 6 to realize the limitation of the connecting arm 6.

[0029] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
