Radar sensor used for motor vehicle and convenient to disassemble, assemble and replace

Abstract

The invention discloses a radar sensor used for a motor vehicle and convenient to disassemble, assemble and replace, relates to the technical field of radar sensors of motor vehicles, and solves the problem that the radar sensor is damaged when the radar sensor is installed at a vehicle head and is in impact contact with an external obstacle. The sensor comprise a sensor main body, two lugs are welded at the periphery of the sensor main body; bottom surfaces of the two lugs are downwards connected with a bottom plate through mounting seats; the bottom plate is also provided with a mounting plate through two columnar upright posts on the bottom surfaces; an outer wall of the sensor main body is provided with a circle of annular support plate close to a top side, a sliding support plate is formed between the bottom mounting plate of the sensor main body and the mounting seat; a set of large-diameter spring attached to a bottom surface of the sensor is installed, and the large-diameter spring elastically supports the bottom of a vehicle-mounted radar sensor installed on the vehicle head, so that when the sensor is installed on the vehicle head for use, if a vehicle body impacts an obstacle forwards, the sensor main body can be pressed inwards and contracted, and the self-protection is achieved.

Description

technical field [0001] The invention relates to the technical field of motor vehicle radar sensors, in particular to a radar sensor for motor vehicles that is easy to disassemble and replace. Background technique [0002] A radar sensor is a type of sensor. It can sense the existence of objects, speed of movement, static distance, angle of objects, etc. by transmitting and receiving microwaves with a frequency of about 24.125 GHz. It adopts planar microstrip antenna technology, which has small size, high degree of integration, and sensitive sensing. Features, the radar sensor applied to the front of the motor vehicle is used to detect the distance between the detected object and the car body when the car is moving forward. [0003] However, due to its installation or application environment, although the radar sensor installed on the front of the motor vehicle can sense the distance between the obstacle and the front of the vehicle when the vehicle is moving forward, someti...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of radar sensor that is used in motor vehicle and is easy to disassemble and replace, to solve the problem that the existing radar sensor installed on the front of the motor vehicle proposed in the above background technology can detect obstacles and obstacles when the vehicle is moving forward. The distance of the front of the car forms the sensing distance, but sometimes the body of the car will still hit the obstacle on the front side due to the lack of braking in time, causing the above-mentioned radar sensor installed on the front side to be damaged by the impact and affecting its service life.
