Problems solved by technology

[0003] In order to ensure the accuracy of the ACC sensor, it is necessary to prevent the surface of the sensor probe from being covered with dust during use. When the vehicle is not driving and parked on the side of the road, it is easy to make the surface covered with more dust due to the lack of wind blowing. This will affect the accuracy of the ACC sensor when in use

Abstract

The invention relates to the technical field of automobile sensors, and discloses a dustproof sealed sensor for an automobile. The dustproof sealed sensor comprises a mounting plate, a shell cover, blocking covers, a through hole and a sliding groove, wherein the shell cover is fixed at the middle position of the back of the mounting plate, a probe is arranged on the surface of the mounting plate at the upper end of the shell cover, a penetrating opening is formed in the surface of the mounting plate at the outer ring of the probe, the probe is arranged in the shell cover in a penetrating mode through the penetrating opening, the probe is connected with a sensor element in the shell cover, the right side of the shell cover is connected with a joint, and the joint is connected to the middle position of the right side of the shell cover. According to the invention, blocking covers which are symmetrically distributed are arranged on the surfaces of the two sides of a mounting plate at the front end of a probe, so that the blocking covers can move leftwards or rightwards to be opened or closed under the condition that a servo motor drives a lead screw to rotate, normal use of the sensor is guaranteed when a vehicle runs, when the vehicle stops, the blocking covers can be arranged at the front end of the probe, the dustproof sealing effect is achieved, and long-term normal use of the sensor is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile sensors, in particular to a dustproof and sealed sensor for automobiles. Background technique [0002] One of the characteristics of the current development of automotive technology is that more and more components are electronically controlled. According to the function of the sensor, it can be classified into sensors that measure temperature, pressure, flow, position, gas concentration, speed, brightness, dry humidity, distance and other functions. They perform their respective duties. Once a certain sensor fails, the corresponding device will work. It will be abnormal or even not working. The role of the sensor in the car is very important. The distance sensor installed in the front of the vehicle continues to scan the road ahead of the vehicle, while the wheel speed sensor collects the speed signal. [0003] In order to ensure the accuracy of the ACC sensor, it is necessary to prevent the ...
