Description

Technical Field

[0001] The utility model relates to the technical field of automotive sensors, and particularly relates to a high-precision automotive sensor. Background Technique

[0002] An automotive sensor is an input device of an automotive computer system, which is used to convert various operating conditions information during the operation of the vehicle (such as vehicle speed, temperature of various media, engine operating conditions, etc.) into electrical signals and transmit them to the computer, so that the engine is in the best working state;

[0003] During the installation process of the existing automotive sensors, by inserting the connection chamber into the installation connector of the vehicle, the detection values of the automotive sensors are transmitted to the central control mechanism. However, during the transmission process, since the connection chamber and the installation connector are not fastened, the connection chamber connected to the automotive sensor is loosened due to the vibration generated during vehicle driving, thereby affecting the signal transmission and reducing the high-precision operation of the automotive sensor.

[0004] In order to overcome the above defects, the prior art (Chinese patent with application number: 201821839695.2, and application date: November 8, 2018) discloses an electric vehicle signal acquisition sensor that is easy to fix. By using fixing columns, guiding plates, connecting shafts and wire-releasing tubes, this device can fix the connecting wires, avoid the situation of breakage of the connecting wires during use, and improve the practicability of this device.

[0005] Although the prior art can solve the problem of fixing the connecting wires, since the rotating parts may be worn during use, thereby affecting their rotation flexibility and precision, the fixing effect of the connecting wires is poor and no sealing effect is set, resulting in gaps at the installation site, which are likely to enter liquids, dust or other impurities, thus reducing the high-precision operation of the automotive sensor. And no fixing structure is set, so the automotive sensor cannot be fixedly installed, further reducing the high precision of the automotive sensor.

[0032] Please refer to Figures 1-7 , the present utility model provides the following technical solutions:

[0033] Embodiment 1: To solve the problem that when a high-precision automotive sensor on the market is in use, since the rotating components may be worn during use, thereby affecting their rotation flexibility and accuracy, resulting in poor fixing effect of the connecting wires and no sealing effect, there are gaps at the installation location, and it is easy for liquids, dust, or other impurities to enter, thus reducing the high-precision operation of the automotive sensor, reference can be made to Attached Figure 1 -Attached Figure 3 and Attached Figure 7, including a housing 2 and a control module 6. A sensor connection chamber 1 is provided at the top of the housing 2, and a threaded component 4 is provided at the bottom of the housing 2.

It further includes: a first mounting plate 5 is fixedly installed at the top of the sensor connection chamber 1. A second mounting plate 7 is movably connected to the top of the first mounting plate 5. A control module 6 is provided at the top of the second mounting plate 7. A gasket 8 is fixedly installed at the top of the first mounting plate 5. Four positioning rods 9 are fixedly connected to the inner wall of the first mounting plate 5 located inside the gasket 8. Three through holes 10 are formed in the inner parts on both sides of the first mounting plate 5. A hexagon bolt 11 penetrates through the through hole 10, and the end of the hexagon bolt 11 penetrates through the second mounting plate 7. A gasket 12 is sleeved on the outer wall of the hexagon bolt 11 at the bottom of the first mounting plate 5. The first mounting plate 5 fits tightly with the gasket 8 and the positioning rods 9, and the gasket 8 and the positioning rods 9 match the inside of the second mounting plate 7. The gasket 8 is made of a certain material and is designed as a loop structure.

[0034] The sensor connection chamber 1 connected through the housing 2 is connected to the control module 6 installed in the external vehicle, so that the first mounting plate 5 installed in the sensor connection chamber 1 fits on the second mounting plate 7. During the process of the first mounting plate 5 fitting on the second mounting plate 7, the first mounting plate 5 drives the four positioning rods 9 and the gasket 8 to insert into the corresponding positions inside the second mounting plate 7. The four positioning rods 9 play a role in accurately positioning the sensor connection chamber 1, ensuring its stability and accuracy during the installation process. The gasket 8 made of silicone further enhances the sealing between the sensor connection chamber 1 and the control module 6, preventing the intrusion of possible liquids, dust or other impurities, thus ensuring the normal operation of the vehicle sensor. Then, manually insert each hexagon bolt 11 through the gasket 12 into the corresponding through hole 10 inside the second mounting plate 7 to fix the sensor connection chamber 1 and the control module 6, thereby improving the stability of the installation of the vehicle sensor and ensuring the high precision of the vehicle sensor.

[0035] Embodiment 2: The vehicle sensor can be fixedly installed, and reference can be made to the attached Figure 1 - attached Figure 2 and attached Figure 4 - attached Figure 6, two sliding grooves 13 are provided on the inner top walls on both sides of the mounting ring plate 3. Fixed plates 14 are fixedly installed on the inner top walls on both sides of the mounting ring plate 3. A screw rod 16 penetrates through the interior of the fixed plate 14. A clamping plate 19 is fixedly connected to the right side of the screw rod 16. Two sliders 20 are fixedly installed on the top of the front and rear sides of the clamping plate 19, and the ends of the sliders 20 penetrate through the sliding grooves 13. A number of threaded holes 15 are provided on the left side of the fixed plate 14. A handle 17 is fixedly installed on the left side of the screw rod 16. A positioning bolt 18 penetrates through the interior of the handle 17, and the end of the positioning bolt 18 penetrates through the threaded hole 15. The hexagonal bolt 11 is detachably connected to the through hole 10 and the gasket 12, and the gasket 12 is made of rubber. The screw rod 16 is movably connected to the fixed plate 14. The clamping plate 19 is fixedly connected to the screw rod 16 and the slider 20, and the slider 20 is slidably connected to the sliding groove 13.

[0036] After the threaded component 4 connected through the housing 2 is installed at the position where the vehicle needs to be installed, manually rotate the two screw rods 16 counterclockwise or clockwise. Thus, the screw rod 16 rotates and moves within the corresponding fixed plate 14, causing the screw rod 16 to drive the clamping plate 19 to move horizontally, thereby adjusting the position of the clamping plate 19. During the movement of the clamping plate 19, the slider 20 is driven to slide within the corresponding sliding groove 13, increasing the stability of the movement of the clamping plate 19. After the two clamping plates 19 move and fit against the shell wall at the vehicle installation position, then manually insert the positioning bolt 18 through the handle 17 and into the corresponding threaded hole 15, fixing the screw rod 16 within the fixed plate 14, thereby fixedly installing the vehicle sensor, enhancing the fixing of the vehicle sensor installation, further improving the high precision of the vehicle sensor, and achieving the stable and accurate installation of the vehicle sensor.
