Description

Technical Field

[0001] This utility model relates to the field of wheel speed sensor technology, and in particular to an improved wheel speed sensor based on chip module processing. Background Technology

[0002] Wheel speed sensors are used to measure the rotational speed of a car's wheels. Wheel speed information is essential for modern cars, as it is required by vehicle dynamic control systems (VDC), electronic stability programs (ESP), anti-lock braking systems (ABS), and automatic transmission control systems.

[0003] For example, the authorization announcement number "CN216209224U" is named a wheel speed sensor with a protection mechanism. Through the cooperation between the sensor and the fixing device, bolts are installed sequentially into the upper and lower parts of two arc-shaped plates and the corresponding threaded holes on the mounting plate. This allows the two arc-shaped plates to fix the cable to the mounting plate, preventing the cable from contacting external objects and causing wear. This solves the problem that existing wheel speed sensors are prone to wear due to excessively long connecting wires and lack of fixing points.

[0004] The above-mentioned and existing technologies have the following drawbacks: when it is necessary to remove the cable from the arc plate, the bolts must be unscrewed before the cable can be removed, which is very laborious; the vertical height of the sensor from the gear ring is not easy to adjust, which affects maintenance and debugging. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an improved wheel speed sensor based on chip module processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Designed based on improved chip module processing, the wheel speed sensor includes a sensor body. A cable is located at the upper front end of the sensor body. A first mounting block is located on the side of the cable. Two spring-loaded assemblies are located on the surface of the first mounting block. One end of each spring-loaded assembly has an opening. The cable is disposed inside the spring-loaded assembly. Two semi-circular blocks are fitted onto the sensor body. Each of the two semi-circular blocks has a vertical plate at both ends. Adjacent vertical plates are threadedly connected by two bolt assemblies. A second mounting block is located on the side of each semi-circular block. A mounting cavity is formed on the surface of the second mounting block. A sliding hole is formed on one inner wall of the mounting cavity. A support block is slidably connected to the sliding hole at one end of each semi-circular block. The support block extends into the mounting cavity and has a slider. A locking device is provided on the surface of the second mounting block, and the slider is fixed by the locking device. A polar axis is located at the lower end of the sensor body, and a toothed ring is located below the polar axis.

[0008] Preferably, the locking device includes a retaining block disposed inside the mounting cavity. Two screws are rotatably connected to one side surface of the retaining block. Two threaded holes communicating with the mounting cavity are opened on the surface of the second mounting block. The screws are threadedly connected to the threaded holes. A nut is provided at the end of each screw away from the retaining block.

[0009] Preferably, the surface of the abutment block near the slider is provided with multiple anti-slip particles.

[0010] Preferably, the surface of the first mounting block has two strip-shaped through holes, and one side surface of the spring assembly is provided with an extension rod, which passes through the strip-shaped through holes and is threaded with a nut.

[0011] Preferably, inclined blocks are provided at both ends of the opening.

[0012] Preferably, the inner wall of the spring assembly is provided with a rubber pad.

[0013] The improved wheel speed sensor based on chip module processing proposed in this utility model has the following advantages: when it is necessary to remove the cable from the spring assembly, there is no need to tighten the bolt component. Due to the elasticity of the spring assembly, the cable can simply be pulled out from the opening, making the operation easy and labor-saving; the vertical height of the sensor from the gear ring is easy to adjust. By using the locking device and tightening the screw to disengage the slider from the clamping block, the vertical height of the sensor from the gear ring can be adjusted without affecting maintenance and debugging.

One end of the spring sheet assembly 4 is provided with an opening 5. The cable 2 is located inside the spring sheet assembly 4. Two semi-circular blocks 6 are sleeved on the sensor body 1. Each end of the two semi-circular blocks 6 is provided with a vertical plate 7. Adjacent vertical plates 7 are threadedly connected by two bolt assemblies 8. A second mounting block 9 is provided on the side of the semi-circular blocks 6. A mounting cavity 10 is opened on the surface of the second mounting block 9. A sliding hole 11 is opened on the inner wall of one side of the mounting cavity 10. A support block 12 is provided at one end of the semi-circular block 6 and is slidably connected to the sliding hole 11. The support block 12 extends into the mounting cavity 10 and is provided with a slider 13. A locking device is provided on the surface of the second mounting block 9. The slider 13 is fixed by the locking device. A polar axis 14 is provided at the lower end of the sensor body 1. A toothed ring 16 with teeth 15 is provided below the polar axis 14.

[0020] The locking device includes a retaining block 17, which is disposed inside the mounting cavity 10. Two screws 18 are rotatably connected to one side surface of the retaining block 17. Two threaded holes 19 communicating with the mounting cavity 10 are opened on the surface of the second mounting block 9. The screws 18 are threadedly connected to the threaded holes 19. A nut 20 is provided at the end of each screw 18 away from the retaining block 17.

[0021] The surface of the abutment block 17 near the slider 13 is provided with multiple anti-slip particles 21. The multiple anti-slip particles 21 serve to prevent slippage.

[0022] Two strip-shaped through holes 22 are formed on the surface of the first mounting block 3. An extension rod 23 is provided on one side surface of the spring assembly 4. The extension rod 23 passes through the strip-shaped through holes 22 and is threadedly connected to a nut 24. By tightening the nut 24, the vertical position of the extension rod 23 can be easily adjusted, allowing the spring assembly 4 to be moved.

[0023] Both ends of the opening 5 are provided with inclined blocks 25. The two inclined blocks 25 facilitate the cable 2 to slide into the spring assembly 4.

[0024] The inner wall of the spring assembly 4 is provided with a rubber pad 26. The rubber pad 26 is provided to prevent the spring assembly 4 from damaging the cable 2.

[0025] Working principle: During installation, two semicircular blocks 6 are pressed against the sensor body 1 and then fixed by multiple bolt assemblies 8. The slider 13 is then slid into the mounting cavity 10. A locking device is installed; by tightening the nut 20, the screw 18 is threaded into the threaded hole 19, causing the clamping block 17 to press against the slider 13, thus fixing the slider 13. When fixing the cable 2, the elastic action of the spring assembly 4 presses the cable 2 from the opening 5 into the spring assembly 4, causing the cable 2 to be snapped onto the spring assembly 4. Using the locking device, the screw 18 is loosened by the nut 20, causing the clamping block 17 to disengage from the slider 13. Then, the support block 12 can be moved, thereby moving the sensor body 1. Position; by loosening the nut 24 from the extension rod 23, and then moving the cable 2 to adjust its position, the external power supply is supplied to the sensor body 1 through the cable 2 to make it work. The polar axis 14 on the sensor body 1 detects the rotation speed of the teeth 15 on the gear ring 16. If it is necessary to remove the cable 2 from the spring assembly 4, there is no need to tighten the bolt component. Due to the elasticity of the spring assembly 4, the cable 2 can be pulled out from the opening 5, which is easy and effortless to operate. The vertical height of this sensor from the gear ring 16 is easy to adjust. By using the locking device and tightening the screw 18 to disengage the slider 13 from the clamping block 17, the vertical height of the sensor from the gear ring 16 can be adjusted without affecting maintenance and debugging.
