Description

Technical Field

[0001] The utility model relates to the field of pressure sensors, in particular to a pressure sensor for automobiles. Background Art

[0002] Automotive pressure sensors are devices used to measure pressure changes in various vehicle systems, including engine control, braking system, tire pressure monitoring system (TPMS), air conditioning system, etc. Pressure sensors can help monitor and control the operating status of these systems and improve vehicle performance, safety and fuel efficiency.

[0003] After searching, the announcement number CN219956773U discloses a pressure sensor for automobiles, including a pressure sensor body, a transmission line is connected to the front side of the upper end of the pressure sensor body, and a fixing frame is installed on the rear side of the upper end of the pressure sensor body; the clamping plate is adjusted to clamp the transmission line, and a section of the transmission line needs to be reserved under the clamping plate, so that when the vehicle is bumped or vibrated during driving or the transmission line is accidentally touched during maintenance, the support block is shock-absorbing and buffered by the spring, so that the connecting block slides inside the through groove through the buffer assembly, and then the bracket slides longitudinally on the front side of the fixing frame through the support mechanism, and the longitudinal movement distance of the bracket can be limited. By reserving a certain length of the transmission line, the transmission line and the pressure sensor body that are separated due to vibration, bump, accidental touch, etc. can be effectively avoided, thereby ensuring the normal use of the pressure sensor body.

[0004] In the above application, the support mechanism slides longitudinally on the front side of the fixed frame and limits the longitudinal movement distance of the bracket. By reserving a certain length of the transmission line, it is possible to effectively avoid the transmission line and the pressure sensor body being separated due to vibration, bumps, accidental touch, etc., thereby ensuring the normal use of the pressure sensor body. However, it is still necessary to fix the transmission line with screws, which is not convenient for reducing the number of required parts and reducing related production costs, which is conducive to reducing product costs.

[0025] Specifically, the sensor body 1 plays a fixing role on the fixed block 3, the fixed plate 2 plays a fixing role on the fixed block 3, the sliding block 6 plays a fixing role on the first pressing block 7, the first sliding groove 4 plays a limiting role on the sliding block 6, and the first spring 5 plays a role in resetting and moving the sliding block 6. The movement of the sliding block 6 drives the first clamping block 8 to slide on the outer wall of the fixed block 3. At this time, the conveying line can be put into the inner wall of the first clamping block 8. At this time, the first pressing block 7 is released. At this time, the first spring 5 rebounds, pushing the sliding block 6 to slide on the inner wall of the first sliding groove 4 and at the same time pushing the first clamping block 8 to slide on the outer wall of the fixed block 3 to fix the conveying line.

[0026] Reference Figure 3 A second slide groove 11 is provided on the outer wall of the rotating disk 9, and a sliding column 12 is slidably connected to the interior of the rotating disk 9;

[0027] Specifically, the rotating disk 9 can limit the sliding column 12 .

[0028] Reference Figure 1 and Figure 3 , the outer wall of the sliding column 12 is slidably connected with a second spring 13, and one end of the second spring 13 is fixedly connected to the inner wall of the rotating disk 9; one end of the sliding column 12 is fixedly connected with a rectangular frame 14, and the other end of the second spring 13 is fixedly connected to the outer wall of the rectangular frame 14; the outer wall of the rectangular frame 14 is fixedly connected with a second pressing block 15, and the lower surface of the second pressing block 15 is fixedly connected with a second clamping block 16, the lower surface of the rotating disk 9 is rotatably connected with a fixed disk 18, and the interior of the fixed disk 18 is fixedly connected with a fixed column 17; the outer wall of the fixed column 17 is rotatably connected to the interior of the rotating disk 9, and the outer wall of the fixed disk 18 is provided with a third sliding groove 19; the outer wall of the fixed column 17 is slidably connected to the inner wall of the third sliding groove 19, and the lower surface of the fixed disk 18 is fixedly connected with a mounting plate 20;

[0029] Specifically, the rectangular frame 14 connects the second push block 15 and the sliding column 12. The sliding column 12 slides inside the rotating disk 9. The rotating disk 9 limits the sliding column 12. The second spring 13 slides on the outer wall of the sliding column 12 to move and reset the second push block 15. The fixed disk 18 fixes the fixed column 17. The rotating disk 9 can rotate on the outer wall of the fixed column 17 to drive the sensor body 1 to adjust the angle. The connecting block 10 is the force point for the rotating disk 9 to rotate. Rotating the connecting block 10 drives the rotating disk 9 to rotate and then drives the sensor body 1 to adjust the angle.

[0030] Working principle: When the sensor is needed, you only need to press the first push block 7 to prompt the first push block 7 to drive the sliding block 6 to slide on the inner wall of the first slide groove 4 opened on the outer wall of the fixed block 3. When the sliding block 6 slides on the inner wall of the first slide groove 4, the sliding block 6 also presses the first spring 5 to contract under the force of the inner wall of the first slide groove 4. At the same time, the movement of the sliding block 6 drives the first clamping block 8 to slide on the outer wall of the fixed block 3. At this time, the conveying line can be placed in the inner wall of the first clamping block 8. At this time, the first push block 7 is released, and the first spring 5 rebounds to push the sliding block 6 slides on the inner wall of the first slide groove 4 and pushes the first clamping block 8 to slide on the outer wall of the fixing block 3 to fix the transmission line, thereby achieving the effect of fixing the transmission line without a screw, thereby reducing the number of required parts and components, reducing related production costs, and helping to reduce product costs. Pressing the second push block 15 causes the second push block 15 to slide on the inner wall of the second slide groove 11 opened on the outer wall of the rotating disk 9 and drives the second clamping block 16 to slide out from the inner wall of the third slide groove 19. At the same time, the movement of the second push block 15 presses the rectangular frame 1 4 drives the sliding column 12 to slide inside the rotating disk 9 and presses the sliding column 12 to shrink. At this time, the rotatable connecting block 10 drives the rotating disk 9 to rotate and then drives the sensor body 1 to adjust the angle. When it is adjusted to a suitable position, stop pressing the second pressing block 15. At this time, the second spring 13 rebounds and pushes the rectangular frame 14 to drive the second pressing block 15 to move, thereby pushing the second clamping block 16 into the inner wall of the third sliding groove 19 opened on the outer wall of the fixed disk 18 again, thereby prompting the rotating disk 9 to drive the sensor body 1 to adjust the angle, thereby achieving the effect of adjusting the installation angle of the pressure sensor for the car, thereby making the sensor adapt to different installation positions and angle requirements, ensuring that it can be correctly installed in the vehicle. The device can not only achieve the effect of fixing the transmission line without a screw, thereby reducing the number of required parts, reducing related production costs, and helping to reduce product costs. In addition, it can also achieve the effect of adjusting the installation angle of the pressure sensor for the car, thereby making the sensor adapt to different installation positions and angle requirements, ensuring that it can be correctly installed in the vehicle.
