Ultrasonic sensor

Abstract

The invention discloses an ultrasonic sensor. The ultrasonic sensor comprises a sensor body (10) and a sensor support (20), the sensor support (20) is of a symmetrical revolving body structure composed of a plurality of clamping jaws (22), one ends of the heads of clamping jaws are connected through a support flange (23), and in the clamping jaws (22), the surfaces of the clamping jaws are provided with rib structures (21) and support clamping grooves (24); the sensor body (10) is a symmetrical revolving body, a sensor flange (11) is arranged at the head of the sensor body (10), and sensor clamping hooks (13) matched with the support clamping grooves (24) are further arranged on the surface of the sensor body (10). The ultrasonic sensor is of a clamping jaw inverted buckle type installation structure, the thickness range of a vehicle bumper capable of being installed is wide, the ultrasonic sensor is installed from outside to inside, the operation space is large, the limitation that the requirement for the operation space from inside to outside is large is overcome, and the installation efficiency is high.

Description

technical field [0001] The invention relates to an ultrasonic sensor, in particular to an ultrasonic sensor installed on an automobile bumper. Background technique [0002] The reverse assist system with ultrasonic sensor as the main component is more and more widely used in automobiles. Ultrasonic sensors are generally installed on the bumper at the front or rear of the car to detect the distance between the car body and obstacles, and when it reaches the set Remind the driver to pay attention when the dangerous distance is set. [0003] At present, the ultrasonic sensors installed on the bumper of the car on the market need to be adapted to the bumper of the body, and the customized structural design is carried out according to the shape and thickness of the bumper, resulting in different installation schemes. However, the thickness range of the bumper is limited, and the thickness uniformity of the bumper is also required, so the versatility is poor. [0004] Moreover, ...

AI Technical Summary

Problems solved by technology

However, the thickness range of the bumper is limited, and there are certain requirements for the thickness uniformity of the bumper, and the versatility is poor.

[0004] Moreover, the ultrasonic sensor installed on the bumper of the car currently on the market is generally installed from the bumper from the inside to the outside. When installing the ultrasonic sensor, the sensor and the harness connector are mostly inserted into each other or the sensor is placed on the mounting bracket. The method of attaching adhesive tape to the inner side of the bumper is limited to the shape and internal structure of the bumper, and the installation efficiency is low, and even some areas cannot be installed because there is no operating space
