Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive sensor technology, and in particular to an anti-detachment automotive sensor. Background Technology
[0002] Automotive sensors are devices installed in various automotive systems to detect and measure information such as vehicle operating status and environmental parameters, and convert this information into electrical signals or other identifiable signals, which are then transmitted to the electronic control unit (ECU) or other related equipment to enable functions such as vehicle control, monitoring, and safety assurance.
[0003] However, in the existing technology, the fixing mechanism of automotive sensors is not strong enough or the connection method is simple, which cannot effectively cope with the dynamic working conditions such as vibration and bumps during vehicle operation. The installation process is not standardized, such as the fixing bolts are not tightened or the installation position is not selected properly, which leads to uneven force on the sensor. The vehicle operating environment is harsh, and long-term vibration and impact will loosen the fixing parts. Especially under complex road conditions, high-frequency vibration can easily cause the threaded connection to loosen or the buckle to fail. Utility Model Content
[0004] The purpose of this invention is to solve the problem that automotive sensors in the prior art are prone to falling off after installation, which affects their normal operation and the safety and reliability of the vehicle. Therefore, this invention proposes an anti-detachment automotive sensor.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-detachment automotive sensor, comprising a sensor body, a fixing mechanism fixedly connected to the bottom of the sensor body, the fixing mechanism comprising a positioning block, a movable plate, an extension rod and a limiting screw, a rotating plate rotatably mounted inside the positioning block, the fixing mechanism fixedly mounted on the lower surface of the sensor body, the movable plate located on the lower surface of the rotating plate, one end of the extension rod fixedly connected to the movable plate, and the limiting screw threadedly mounted on the end of the extension rod.
[0006] Preferably, a protrusion is fixedly installed on the upper surface of the rotating plate, and a worm gear is rotatably connected to the outer wall of the protrusion.
[0007] Preferably, a worm gear is rotatably mounted at the edge of the positioning block, and the worm gear meshes with a worm wheel.
[0008] Preferably, the end of the worm gear is fixedly provided with four corner grooves.
[0009] Preferably, an anti-detachment plate is fixedly installed on the upper surface of the movable plate, and the anti-detachment plate is slidably connected to the positioning block.
[0010] Preferably, a connecting block is rotatably mounted on the lower surface of the anti-detachment plate, and the connecting block is slidably connected to the rotating plate.
[0011] Preferably, a receiving groove is provided at the junction of the rotating plate and the connecting block.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, rotating the worm gear can drive the worm wheel to rotate, which in turn causes the rotating plate to rotate. When the rotating plate rotates, it can drive the movable plate, extension rod, and limiting screw to move. One side of the extension rod has an irregular shape, which can be fastened to different installation structures. At the same time, the limiting screw is threaded on the end of the extension rod, which can realize the limiting and fixing of the installation position, making it easy to adjust the fixing position. Moreover, the threaded connection can enhance the firmness of the fixation, effectively prevent the sensor from falling off, and improve the stability and reliability of the sensor after installation.
[0014] 2. In this utility model, the four corner slots facilitate the insertion of tools into the rotating worm gear, making operation more convenient. The anti-detachment plate and the positioning block are slidably connected, which can prevent the movable plate from shaking and enhance the structural stability. When the rotating plate rotates, the receiving groove pushes the connecting block. Since the anti-detachment plate is restricted in the positioning block, the connecting block will drive the movable plate and the anti-detachment plate to slide along the direction of the receiving groove.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an anti-detachment automotive sensor, including a sensor body 1. A fixing mechanism 2 is fixedly connected to the bottom of the sensor body 1. The fixing mechanism 2 includes a positioning block 21, a movable plate 22, an extension rod 23, and a limiting screw 24. A rotating plate 29 is rotatably installed inside the positioning block 21. The fixing mechanism 2 is fixedly installed on the lower surface of the sensor body 1. The movable plate 22 is located on the lower surface of the rotating plate 29. One end of the extension rod 23 is fixedly connected to the movable plate 22. The limiting screw 24 is threadedly installed on the end of the extension rod 23. A protrusion 25 is fixedly installed on the upper surface of the rotating plate 29. A worm gear 26 is rotatably connected to the outer wall of the protrusion 25. A worm 27 is rotatably installed at the edge of the positioning block 21. The worm 27 is meshed with the worm gear 26.
[0023] The specific setup and function of this embodiment are described below. In the fixing mechanism 2 at the bottom of the sensor body 1, a rotating plate 29 is rotatably installed inside the positioning block 21. The outer wall of the protrusion 25 on the upper surface of the rotating plate 29 is rotatably connected to the worm gear 26. A worm 27 that meshes with the worm gear 26 is rotatably installed on the edge of the positioning block 21. Rotating the worm 27 can drive the worm gear 26 to rotate, thereby causing the rotating plate 29 to rotate. The movable plate 22 on the lower surface of the rotating plate 29 is connected to the limiting screw 24 through the extension rod 23. When the rotating plate 29 rotates, it can drive the movable plate 22, the extension rod 23, and the limiting screw 24 to move. One side of extension rod 23 has an irregular shape, allowing it to be fastened to different mounting structures. Meanwhile, the limiting screw 24 is threaded onto the end of extension rod 23, which can limit and fix the installation position. Through the meshing transmission of worm gear 27 and worm wheel 26, components such as rotating plate 29 and movable plate 22 can be moved and fixed by limiting screw 24. This structure provides stable transmission, facilitates adjustment of the fixed position, and enhances the firmness of the fixation through threaded connection, effectively preventing the sensor from falling off, improving the stability and reliability of the sensor after installation, and ensuring that the sensor can work normally during vehicle operation.
[0024] Example 2: Figure 3 and Figure 4As shown, a four-corner groove 28 is fixedly provided at the end of the worm gear 27, an anti-detachment plate 211 is fixedly installed on the upper surface of the movable plate 22, the anti-detachment plate 211 is slidably connected to the positioning block 21, a connecting block 212 is rotatably installed on the lower surface of the anti-detachment plate 211, the connecting block 212 is slidably connected to the rotating plate 29, and a receiving groove 210 is provided at the junction of the rotating plate 29 and the connecting block 212.
[0025] The overall effect of this embodiment is that tools can be inserted into the four corner slots 28 at the end of the worm 27, facilitating the rotation of the worm 27. The anti-detachment plate 211 on the upper surface of the movable plate 22 is slidably connected to the positioning block 21, restricting the movement direction of the movable plate 22. The connecting block 212, rotatably mounted on the lower surface of the anti-detachment plate 211, is slidably connected to the rotating plate 29. The receiving groove 210 at the junction of the rotating plate 29 and the connecting block 212 provides space for sliding. When the worm 27 rotates, it drives the rotating plate 29 to rotate through the worm wheel 26. When the rotating plate 29 rotates, it pushes the connecting block 212 using the receiving groove 210. Since the anti-detachment plate 211 is restricted to the positioning block... In step 21, the connecting block 212 will drive the movable plate 22 and the anti-detachment plate 211 to slide along the direction of the receiving groove 210, so that the extension rod 23 and the limiting screw 24 move to the fixed position. The four corner grooves 28 facilitate the insertion of tools into the rotating worm gear 27, making the operation more convenient. The anti-detachment plate 211 is slidably connected to the positioning block 21, which can prevent the movable plate 22 from shaking and enhance the structural stability. The sliding cooperation between the connecting block 212 and the rotating plate 29 and the setting of the receiving groove 210 enable the movable plate 22 to move smoothly when the rotating plate 29 rotates, ensuring that the limiting screw 24 is accurately positioned and fixed, further improving the anti-detachment effect and installation reliability of the fixing mechanism 2.
[0026] The usage method and working principle of this device are as follows: First, place the fixing mechanism 2 at the bottom of the sensor body 1 in the installation position. Then, use the irregular shape of one side of the extension rod 23 to fasten it onto the corresponding installation structure. Next, insert the adapter tool into the four-corner groove 28 at the end of the worm gear 27. Rotate the worm gear 27. Through the meshing transmission between the worm gear 27 and the worm wheel 26, the protrusion 25 and the rotating plate 29 will rotate. When the rotating plate 29 rotates, it slides in cooperation with the connecting block 212 at the receiving groove 210. Because the anti-detachment plate 211 and the positioning block 21 are slidably connected, restricting the movement direction of the movable plate 22, the connecting block 212 will drive the movable plate 22. The anti-detachment plate 211 slides along the positioning block 21, thereby causing the extension rod 23 and the limiting screw 24, which are fixedly connected to the movable plate 22, to move. Finally, the limiting screw 24 is threaded onto the end of the extension rod 23 to limit and fix the installation position, ensuring that the sensor body 1 is securely installed and preventing it from falling off.
[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
