Description

Technical Field

[0001] The utility model relates to the technical field of wheel speed sensors, in particular to an anti-falling automobile wheel speed sensor. Background Art

[0002] Wheel speed sensors play a vital role in modern automobiles. They are one of the key sensors required for vehicle dynamic control systems, vehicle electronic stability programs, anti-lock braking systems, and automatic transmission control systems. In addition, with the development of intelligence and electrification in the automotive industry, wheel speed sensors are increasingly used in the fields of autonomous driving and intelligent transportation.

[0003] When the existing automobile wheel speed sensor is in use, the wheel speed sensor is more likely to fall off during vehicle driving, especially when passing through complex road conditions or encountering severe vibrations. This will cause the sensor to separate from the wheel or other vehicle parts, thereby affecting the normal operation of the vehicle, which not only increases maintenance costs, but also affects the reliability and service life of the vehicle.

[0011] Preferably, the inner wall of the threaded hole is threadedly connected with a screw, and the outer wall of the screw is threadedly connected with a nut 2.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, by rotating the nut 1 on the outer wall of the bolt, the fixing plate 1 is fixed to the bearing body, which can provide a strong and stable connection force to ensure that the sensor can be firmly installed on the car under various complex driving conditions. Secondly, through the cooperation between the clamping plate and the fixing block, the fixing block can make the wires arranged more neatly and orderly, which helps to optimize the line layout inside the vehicle and reduce the potential fault risk caused by the chaos of the lines.

[0024] The effect achieved by the entire embodiment 1 is that, firstly, the device body is fixed to the bearing body 1 of the vehicle by rotating the nut 5 on the outer wall of the bolt 3 through the cooperation between the bolt 3 and the nut 5; secondly, the clamping plate 7 can be clamped on the outer wall of one of the two connecting frames 2, and the clamping plate 7 is fixedly connected to the fixing block 8, and the wire 13 passes through the hole 9 on the outer wall of the fixing block 8, which can effectively reduce the pulling and friction on the wire 13, reduce the risk of wear and breakage of the outer skin of the wire 13, and ensure that the conductor inside the wire 13 transmits signals normally.

[0025] Embodiment 2, as Figure 1-Figure 4As shown, a wheel speed sensor body 12 is arranged on one side of the outer wall of the connecting plate 2 10, and two wires 13 are arranged on the outer wall of the wheel speed sensor body 12, and the outer walls of the two wires 13 are movably inserted in the inner walls of the two holes 9, and two fixing plates 2 14 are fixedly installed on the outer wall of the connecting plate 2 10, and springs 15 are fixedly installed on the opposite sides of the two fixing plates 2 14, and dampers 16 are fixedly installed on the inner walls of the two springs 15, and connecting plates 3 17 are fixedly installed on the opposite sides of the two fixing plates 2 14, and a fixing ring 18 is fixedly installed between the outer walls of the two connecting plates 3 17, and a threaded hole 19 is opened on the outer wall of the fixing ring 18, and a screw 20 is threadedly connected to the inner wall of the threaded hole 19, and a nut 21 is threadedly connected to the outer wall of the screw 20.
