Problems solved by technology

[0003] At present, the ultrasonic sensor installed on the bumper of the car on the market is generally installed from the inside to the outside of the bumper. This installation structure is connected to the bumper opening by the mounting bracket or the bracket is glued to the inner surface of the bumper. The new ultrasonic sensor is fixed in a new way, but it is limited to the bumper shape and internal structure, the installation efficiency is low, and even some areas have no operating space and cannot be installed
[0004] A small part of the installation structure is a structure that is installed from the outside to the inside of the bumper. This installation structure is mostly fixed on the bumper by snap-fitting metal shrapnel. It is necessary to customize the sensor installation structure according to the thickness of the bumper, which has poor adaptability; the shrapnel is a separate type. Multiple parts, difficult assembly, low efficiency, and unreliable installation

Embodiment 1

[0027] The preferred embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, a novel ultrasonic sensor of the present invention includes a sensor body (the head of the sensor) 100 , and the sensor body is connected to a socket 300 through a wire 200 .

[0029] Such as figure 2 , 3 As shown, the sensor body 100 includes a mounting body 30 and a rear cover 60 , the mounting body 30 has a buffer bushing 10 , an ultrasonic probe 40 and a circuit board 50 inside, and the circuit board 50 is connected to the socket 300 through a wire 200 . There are a plurality of integrally formed shrapnels 20 on the periphery of the installation body 30, and two shrapnels are shown in the figure. The integrally formed shrapnels are made of rigid materials, such as stainless steel, spring steel, hot-dip galvanized steel, and beryllium. Copper and more.

[0030] Such as Figure 4 As shown, the integ...

Embodiment 2

[0036] When the bumper 70 has a certain inclination angle in the vertical direction, the corresponding sensor and its shrapnel have a certain inclination angle, such as Figure 5 , 6 shown.

[0037] The composition and structure of the sensor body of this embodiment is the same as that of Embodiment 1. It includes an installation body 30 and a rear cover 60 , the interior of the installation body 30 is a buffer bushing 10 , an ultrasonic probe 40 and a circuit board 50 , and the circuit board 50 is connected to the socket 300 through wires 200 . The overall structure of the sensor body also has an inclination angle corresponding to the inclination angle of the bumper 70 . When installed on the bumper, the overall structure of the sensor body is horizontal.

[0038] shrapnel structure such as Figure 7 As shown, the lengths of the L-shaped bends 21 on both sides of the straight portion 24 are not equal, and the lengths of the cantilevers 22 on both sides are equal, that is,...

Abstract

The invention discloses a novel ultrasonic sensor, which comprises a sensor main body, wherein the sensor main body comprises a mounting body and a rear cover, a plurality of integrally-formed elasticpieces are arranged on the periphery of the installation body, the integrally-formed elastic pieces are made of rigid materials, each integrally-formed elastic piece comprises a straight part and L-shaped bends arranged on the two sides of the straight part, the L-shaped bends are connected with cantilevers inclining outwards, and the cantilevers are connected with clamping jaws inclining inwards. By adopting the integrated elastic pieces for clamping a bumper, the thickness range of vehicle bumpers capable of being installed is wide, and the installation efficiency is high.

Description

technical field [0001] The invention relates to a novel ultrasonic sensor, in particular to a novel ultrasonic sensor with high installation efficiency. Background technique [0002] Ultrasonic sensors are generally used in reversing assistance systems. As the main components of reversing assistance systems, ultrasonic sensors are 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 Obstacle distance, and remind the driver to pay attention when the set dangerous distance is reached. [0003] At present, the ultrasonic sensor installed on the bumper of the car on the market is generally installed from the inside to the outside of the bumper. This installation structure is connected to the bumper opening by the mounting bracket or the bracket is glued to the inner surface of the bumper. This method fixes the new ultrasonic sensor, but it is limited to the shape of the bumper and the intern...
