[0002] The position sensor on the car is usually installed on the steering gear. Since the steering gear is located at the bottom of the cab and exposed to the outside, installing the position sensor on the steering gear is not only easy to be hit by gravel, but also cannot protect the position sensor from dust and water, resulting in a high failure rate of the position sensor. For example, as shown in the installation structure of the steering angle sensor of a heavy-duty vehicle with Chinese patent application number CN201721505276.0, the steering angle sensor is installed on the steering column assembly near the steering wheel through an annular connecting frame; the steering column assembly includes a steering shaft and a steering column tube, the steering column tube is sleeved outside the steering shaft, the upper end of the steering shaft protrudes outside the steering column tube, and the steering wheel is connected to the upper end of the steering shaft.

[0003] However, when the sensor is installed on the steering column through the protective cover, since the traditional sensor is installed on the steering column in a set manner, when the sensor is damaged, it is necessary to first remove the steering column from the steering wheel, and then remove the sensor from the steering column. This process is not only time-consuming and labor-intensive, but also inconvenient for quick replacement of the sensor. Utility Model Content
