Problems solved by technology

The current structure installed from the outside to the inside mostly uses iron shrapnel or elastic materials or is installed by plastic clamping. The plastic clamping method is limited by the structural design, and the sensor installation structure needs to be customized according to the thickness of the bumper. It can be installed The thickness range of the vehicle bumper is relatively narrow, and there are many such structural components on the market. The general bracket includes a bracket body, bracket gasket and other structures, which is difficult to assemble, and the cost of products and molds is high.

Embodiment 1

[0028] The preferred embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, a novel ultrasonic sensor of the present invention is mainly composed of an ultrasonic probe 10 , a bracket 20 and a sensor 40 . The bracket 20 is sleeved on the periphery of the sensor 40, and the bracket 20 is an integrally formed plastic bracket.

[0030] Such as figure 2 , 5 As shown, the bracket 20 includes a structural main body 100 and a clamping structure 200 arranged on the periphery of the structural main body 100. The structural main body 100 is used to fit on the periphery of the sensor, and the clamping structure 200 is clamped with the mounting hole. The sensor is generally installed on the bumper of a car. , the mounting holes are provided on the bumper. The clamping structure 200 includes a clamping body 25, radially arranged airfoil structures (22, 24) and axially arranged conical stru...

Embodiment 2

[0034] Such as Figure 6 and 7 As shown, the clamping structure of this embodiment is the same as that of Embodiment 1. The clamping structure 200 includes a clamping main body 25, radially arranged airfoil structures (22, 24) and axially arranged cones. Shaped structure (21, 23), the difference is that the supporting ribs 22 of the airfoil structure are connected to the main body 25 through the L-shaped structure 34, the outer surface 35 of the L-shaped structure 34 is linear, and the inner surface 36 is arc-shaped modeling. It avoids the complex structure of the mold here, which simplifies the structure of the mold while maintaining the function of the clamping structure, and reduces the cost of the mold product.

Embodiment 3

[0036] Such as Figure 8 and 9 As shown, the clamping structure of this embodiment is the same as that of Embodiment 1. The clamping structure 200 includes a clamping main body 25, radially arranged airfoil structures (22, 24) and axially arranged cones. Shaped structure (21, 23), the difference is that the supporting rib 22 is connected to the clamping body 25 through the L-shaped structure 44, the outer side 45 of the L-shaped structure 44 is linear, and the inner side 46 is a slope. It avoids the need for complex electric discharge machining on the mold here, simplifies the clamping structure, improves the elasticity of the L-shaped structure, makes the installation of sensors smoother and reduces the cost of mold products.

Abstract

The invention discloses a novel ultrasonic sensor. The novel ultrasonic sensor comprises a support sleeved on the periphery of the sensor, the support is an integrally formed plastic support, the support comprises a structure main body and a clamping structure arranged on the periphery of the structure main body, the structure main body is used for being sleeved on the periphery of the sensor, theclamping structure is clamped with a mounting hole, the clamping structure comprises a clamping main body, a radially-arranged wing-shaped structure and an axially-arranged conical structure, the wing-shaped structure comprises a supporting rib position, and the supporting rib position comprises an inner-side arc-shaped structure and an outer-side arc-shaped structure which are in interference fit with the mounting hole; and the conical structure comprises a guide structure and an axial limiting structure. The integrated plastic support is clamped to a bumper, the inner side wall of an opening of the bumper is extruded through elasticity and design interference fit of plastic, the sensor can be effectively fixed and prevented from rotating in the radial direction, and the vehicle bumper capable of being installed is wide in thickness range and high in installation efficiency.

Description

technical field [0001] The invention relates to a novel ultrasonic sensor, in particular to a novel ultrasonic sensor which is easy to install. 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 sensors installed on the bumper of automobiles on the market generally have two installation structures: the structure installed from the outside to the inside of the bumper and the structure installed from the inside to the outside. The structure installed from the outside to the inside is easy to install and widely used because the sensor is installed from the outside to the insid...
