Description

Technical Field

[0001] The utility model relates to the technical field of vehicle sensors, and more specifically, to a vehicle pressure sensor installation mechanism. Background Art

[0002] At present, the automotive sensors on the market are composed of two layers of elastic substrates and an intermediate insulating layer. The upper and lower layers of the elastic substrates are provided with conductive layers on opposite sides, and a through hole is provided in the middle of the insulating isolation layer. The through hole of the insulating isolation layer corresponds to the sensing module. When there is a passenger in the seat, the upper and lower sensing modules are in contact and conductive, and then output signals. The vehicle controller determines whether to alarm based on the different signals output by the seat pressure sensor.

[0003] This type of automotive sensor is installed between the seat suspension and the foam and is fixed to the seat suspension through a support plate. In actual use, the support plate is mostly fixed to the base plate of the sensor through bolts, and the support plate is fixed to the seat suspension with bolts. As a result, when inspecting the sensor, the bolts between the support plate and the sensor need to be removed before the sensor can be disassembled and removed. After the inspection is completed, the sensor can be installed back with bolts. Such operation is not only time-consuming and labor-intensive, but also reduces the efficiency of inspection, so it needs to be improved. Utility Model Content

The middle parts of the opposite surfaces of the two movable plates 302 are respectively hinged with connecting rods 305. There are two connecting rods 305 with the same shape and size. The connecting rod 305 will move the clamping rod 301.

[0034] When the adjacent ends of the two connecting rods 305 rotate, since the two connecting rods 305 are respectively hinged to the two movable plates 302, as the connecting rod 305 rotates, the connecting rod 305 will generate a thrust on the movable plate 302, pushing the two movable plates 302 to move away from each other along the outer surface of the limit rod 303 and compress the first spring 304, so that the clamping rod 301 fixedly connected to the movable plate 302 moves together, thereby releasing the clamping of the two clamping rods 301 on the pressure sensor 2, thereby facilitating the disassembly and installation of the pressure sensor 2, thereby improving the convenience of overhauling the pressure sensor 2.

[0035] Wherein, the rotating mechanism 4 includes:

[0036] The round block 401 is movably sleeved on the inner surface of the middle end of the support plate 1. The inner surface of the round block 401 is movably sleeved on the outer surface of the connecting rod 305. The upper and lower ends of the inner part of the round block 401 are respectively fixedly sleeved with round rods 402. There are two round rods 402. The outer surfaces of the two round rods 402 are respectively movably sleeved on the inner surfaces of the proximal ends of the two connecting rods 305.

[0037] A fixing rod 403 is fixedly sleeved on the inner surface of the middle end of the round block 401, and first handles 404 are fixedly sleeved on the left and right sides of the outer surface of the round block 401. There are two first handles 404, and the two first handles 404 are movably sleeved on the inner surfaces of the left and right ends of the support plate 1, and the opposite surfaces of the two first handles 404 are movably connected to the left and right ends of the round block 401.

[0038] When the first handle 404 is rotated, the first handle 404 will drive the round block 401 to rotate through the fixing rod 403, so that the round rod 402 fixedly sleeved with the round block 401 will rotate together, and then the round rod 402 will drive one end of the connecting rod 305 to rotate.

[0039] The inner walls of the adjacent sides of the top ends of the two clamping rods 301 are respectively provided with limiting grooves 5 , and the bottom ends of the limiting grooves 5 are movably sleeved with limiting blocks 6 .

[0040] The inner surface of the limiting groove 5 and the outer surface of the limiting block 6 are both smooth, ensuring that the limiting block 6 will not get stuck when moving along the inside of the limiting groove 5 .

[0041] Among them, the inner surfaces of the top ends of the two clamping rods 301 are respectively movably connected with extension rods 7, and the outer surfaces of the extension rods 7 are fixedly connected to the outer surface of the limit block 6. There are two extension rods 7, and the top ends of the two extension rods 7 respectively penetrate the two clamping rods 301 and extend to the outside of the clamping rods 301 and are fixedly installed with stop blocks 8. The bottom end of the stop block 8 is movably connected to the top end of the pressure sensor 2.

[0042] Due to the presence of the extension rod 7 and the stopper 8, the pressure sensor 2 will be blocked, thereby improving the installation stability of the pressure sensor 2 and preventing the pressure sensor 2 from falling off.

[0043] Among them, the two extension rods 7 are respectively provided with a card slot 9 on the back side thereof, and a card rod 10 is movably sleeved inside the card slot 9. The other end of the card rod 10 passes through the clamping rod 301 and extends to the outside of the clamping rod 301 and is fixedly installed with a second handle 11. The outer surface of the second handle 11 is movably connected to the outer surface of the clamping rod 301.

[0044] When the second handle 11 is pulled, the card rod 10 will move along with the second handle 11, thereby separating the card rod 10 and the card slot 9, releasing the lock of the extension rod 7 by the card rod 10. The card slots 9 are evenly arranged on the outer surface of the extension rod 7, so when the card rod 10 is engaged with different card slots 9, the extension rod 7 can be fixed at different positions.

[0045] Among them, there are two clamping rods 10, and the outer surfaces of the two clamping rods 10 are respectively fixedly sleeved with circular plates 12 located inside the clamping rod 301. There are two circular plates 12, and the back sides of the two circular plates 12 are respectively fixedly installed with second springs 13. The other end of the second spring 13 is fixedly connected to the inner surface of the clamping rod 301, and the second spring 13 will reset the circular plate 12.

The opposite surfaces of the two positioning plates 14 are movably connected to the left and right ends of the pressure sensor 2 respectively, and mounting holes 15 are opened on the left and right sides of the front end of the support plate 1.

[0048] The existence of the two positioning plates 14 will facilitate the positioning of the pressure sensor 2 , while the mounting holes 15 will facilitate the installation and fixation of the support plate 1 .

[0049] The working principle and use process of this utility model:

[0050] First, when the operator inspects the pressure sensor 2, he turns the first handle 404 so that the first handle 404 drives the round block 401 and the round rod 402 to rotate through the fixed rod 403, so that the proximal ends of the two connecting rods 305 movably sleeved with the round rod 402 rotate together, and then the other ends of the two connecting rods 305 respectively generate a thrust on the two movable plates 302, pushing the two movable plates 302 to move away from each other along the outer surface of the limit rod 303 with the two clamping rods 301 and compressing the first spring 304 until the clamping rod 301 is completely separated from the pressure sensor 2, and then the pressure sensor 2 can be removed. After the inspection is completed, the pressure sensor 2 is placed between the two positioning plates 14 and the first handle 404 is released. At this time, under the restoring action of the first spring 304, the clamping rod 301 will be restored to its original position, thereby clamping and fixing the pressure sensor 2. With the cooperation of various mechanisms, the pressure sensor 2 can be quickly disassembled and installed, thereby improving the convenience of the pressure sensor 2 during inspection.

[0051] When installing pressure sensors 2 of different specifications, before clamping and fixing the pressure sensor 2 by the clamping rod 301, the operator pulls the second handle 11, so that the clamping rod 10 moves with the circular plate 12 along with the second handle 11 and compresses the second spring 13 until the clamping rod 10 and the clamping slot 9 are separated, and then pulls the stopper 8, so that the stopper 8 moves along the inner surface of the clamping rod 301 with the extension rod 7 until the height of the stopper 8 matches the pressure sensor 2, and then releases the second handle 11. Since the clamping slot 9 is evenly arranged on the outer surface of the extension rod 7, the circular plate 12 and the clamping rod 10 will return to their original positions under the restoring action of the second spring 13, so that the clamping rod 10 is embedded in another clamping slot 9. Then the operator can rotate the first handle 404 and fix the pressure sensors 2 of different specifications by the clamping rod 301. The operator can block the pressure sensors 2 of different specifications by changing the positions of the extension rod 7 and the stopper 8, thereby improving the stability of the installation of the pressure sensor 2 and preventing it from falling off.
