Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to an automotive sensor with an anti-detachment mounting structure. Background Technology

[0002] Based on their function, automotive sensors can be classified into sensors that measure temperature, pressure, flow rate, position, gas concentration, speed, light intensity, humidity, distance, and other functions. Hydraulic sensors, among others, use threaded connections; however, during vehicle movement, vibrations can easily cause these threaded connections to loosen.

[0003] Chinese patent application date: September 4, 2023, publication number: CN220594804U, discloses an automotive sensor with an anti-detachment mounting structure, relating to the field of automotive parts technology. The sensor includes a mounting plate with a fixed base on its front side, a connecting base on its front side, and an automotive sensor body inside the connecting base. Mounting holes are provided at both ends of the mounting plate. This invention utilizes the cooperation of a plug, guide rod, square block, locking block, spring one, connecting rod, moving plate, sliding rod, and spring two. When installation is required, pushing the connecting rod moves the locking block to lock it in place, simultaneously stretching spring one. Releasing the moving plate, due to the elasticity of spring two, pushes one end of the moving plate to restrict the position of the locking block. This solves the problem of the automotive sensor failing to prevent detachment and falling, achieving an effect of anti-detachment and simple, convenient installation.

[0004] In this technical solution, the elasticity of the spring is used to lock the locking block and the insertion block together to prevent the sensor from falling off; however, the structure of this technical solution is relatively complex, and the mounting plate still needs to be installed with bolts, screws, etc., which are still prone to loosening under vibration, so further improvements can be made. Summary of the Invention

[0005] In order to solve the problems existing in the background art, this utility model proposes an automotive sensor with an anti-detachment mounting structure.

[0006] A car sensor with an anti-detachment mounting structure includes a hydraulic sensor and a container housing. A threaded sleeve is welded to the top of the container housing, and a threaded connector is fixedly installed at the bottom of the hydraulic sensor. The threaded sleeve and the threaded connector are threadedly connected. A snap-fit ​​assembly is provided between the threaded sleeve and the hydraulic sensor. A protective tube is fixedly installed on the outside of the snap-fit ​​assembly, and the protective tube is sleeved on the outside of the threaded sleeve.

[0007] Based on the above, the snap-fit ​​assembly includes a washer, which is sleeved on the outside of the threaded joint. The washer slides vertically relative to the threaded sleeve. A spring is fixedly arranged between the bottom of the washer and the top of the threaded sleeve. A groove is provided on the top of the washer, and a boss is fixedly installed at the bottom of the hydraulic sensor. The boss is inserted into the groove.

[0008] Based on the above, the bottom array of the washer ring is fixed with a sliding rod, and the top array of the threaded sleeve is provided with a sliding hole, and the sliding rod is slidably connected in the sliding hole.

[0009] Based on the above, the protective tube is fixedly installed on the outer wall of the gasket ring, and an annular groove is provided on the outer wall of the bottom end of the protective tube, and a rotating ring is rotatably connected in the annular groove.

[0010] Based on the above, the rotating ring has a through-hole, the hydraulic sensor has a column fixedly installed on the top, the column has a blocking cap fixedly installed on the top, and the blocking cap is attached to the top edge of the rotating ring.

[0011] Based on the above, a convex ball is fixedly installed on the top of the rotating ring, and a positioning piece is fixedly installed on the outer wall of the bottom end of the protective tube. The two ends of the positioning piece are bent upwards, and a circular groove is opened at the center of the positioning piece. The convex ball is engaged in the circular groove.

[0012] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model allows the washer to slide only vertically relative to the threaded sleeve. When the boss is inserted into the groove, it can suppress the rotation of the threaded joint relative to the threaded sleeve, thus preventing the threaded joint from falling off the threaded sleeve. When disassembling, align the clearance opening with the blocking cap, push the protective tube downward, and then twist the hydraulic sensor to remove it. It has the advantages of simple structure, stable installation to prevent falling off, and easy disassembly. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-5 As shown, an automotive sensor with an anti-detachment mounting structure includes a hydraulic sensor 100 and a container housing 200. A threaded sleeve 300 is welded to the top of the container housing 200, and a threaded connector 400 is fixedly mounted on the bottom of the hydraulic sensor 100. The threaded sleeve 300 and the threaded connector 400 are threadedly connected. A snap-fit ​​assembly 500 is provided between the threaded sleeve 300 and the hydraulic sensor 100. The snap-fit ​​assembly 500 inhibits the rotation of the threaded connector 400 relative to the threaded sleeve 300, preventing loosening between the threaded connector 400 and the threaded sleeve 300 under vibration. A protective tube 600 is fixedly mounted on the outside of the snap-fit ​​assembly 500, and the protective tube 600 is sleeved on the outside of the threaded sleeve 300. The protective tube 600 covers the gap between the snap-fit ​​assembly 500 and the threaded sleeve 300 to prevent foreign objects from entering the gap.

[0021] In use, the snap-fit ​​assembly 500 includes a washer 503, which is sleeved on the outside of the threaded connector 400. The washer 503 slides vertically relative to the threaded sleeve 300. Springs 504 are fixedly arranged between the bottom of the washer 503 and the top of the threaded sleeve 300. A groove 505 is formed on the top of the washer 503, and a boss 506 is fixedly installed on the bottom of the hydraulic sensor 100, which is inserted into the groove 505. When the hydraulic sensor 100 is installed on the container shell 200, it is screwed onto the threaded sleeve 300 through the threaded connector 400. After the threaded connector 400 descends a certain distance, the boss 506 presses against the top of the washer 503, compressing the springs 504. Then, the threaded connector 400 rotates a certain angle, aligning the boss 506 with the groove 505. Under the elastic action of the springs 504, the washer 503 moves upward, causing the boss 506 to embed into the groove 505. This prevents the threaded joint 400 from continuing to rotate relative to the threaded sleeve 300; In practice, the bottom array of the washer 503 is fixed with a sliding rod 501, and the top array of the threaded sleeve 300 is provided with a sliding hole 502, with the sliding rod 501 slidably connected in the sliding hole 502. This allows the washer 503 to move only up and down relative to the threaded sleeve 300, and after the boss 506 is inserted into the groove 505, it stably inhibits the rotation of the threaded joint 400 relative to the threaded sleeve 300.

[0022] Specifically, the protective tube 600 is fixedly installed on the outer wall of the gasket 503. An annular groove 601 is formed on the outer wall of the bottom end of the protective tube 600, and a rotating ring 700 is rotatably connected in the annular groove 601. When disassembling the hydraulic sensor 100, the gasket 503 can be moved downward by pushing the protective tube 600 and the rotating ring 700 downward, causing the boss 506 to disengage from the groove 505. Then, the hydraulic sensor 100 can be rotated to remove it.

[0023] A clearance opening 701 is provided through the edge of the rotating ring 700. A column 800 is fixedly installed on the top of the hydraulic sensor 100, and a blocking cap 900 is fixedly installed on the top of the column 800. The column 800 is located outside the edge of the rotating ring 700, and the top view projection of the blocking cap 900 is located on the edge of the rotating ring 700. During the disassembly of the hydraulic sensor 100, when pushing the protective tube 600 and the rotating ring 700 downward, the rotating ring 700 can be rotated first to align the clearance opening 701 with the blocking cap 900. The rotating ring 700 moves downward, and the blocking cap 900 passes through the clearance opening 701. Then, the rotating ring 700 is rotated to displace the clearance opening 701 from the blocking cap 900. Then, the protective tube 600 and the rotating ring 700 are released. Under the elastic action of the spring 504, the protective tube 600 and the rotating ring 700 move upward, and the blocking cap 900 fits against the top edge of the rotating ring 700. This keeps the boss 506 and the washer 503 separated.

[0024] When the boss 506 is inserted into the groove 505, the rotating ring 700 is positioned above the blocking cap 900. By rotating the rotating ring 700, the clearance opening 701 is misaligned with the blocking cap 900, allowing the blocking cap 900 to block the rotating ring 700 from the bottom. This prevents the washer ring 503, protective tube 600, and rotating ring 700 from moving too far downwards under vibration, which could cause the washer ring 503 to detach from the boss 506.

[0025] In reality, a convex ball 702 is fixedly installed on the top of the rotating ring 700, and a positioning piece 602 is fixedly installed on the outer wall of the bottom end of the protective tube 600. The two ends of the positioning piece 602 are bent upwards, and a circular groove 603 is opened in the center of the positioning piece 602. When the convex ball 702 is engaged in the circular groove 603, the clearance opening 701 is just aligned with the blocking cap 900, which plays a positioning role.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
