The vehicle-mounted ultrasonic wave sensor consists of a sensor probe, a rubber composite sleeve and an end cover, wherein the sensor probe is arranged on the rubber composite sleeve; the end cover is arranged on the rubber composite sleeve; and positioning card is arranged on the rubber composite sleeve. The vehicle-mounted ultrasonic wave sensor has a simple structure, improves the interference resistant capacity and sensitivity, and improves the production efficiency of products effectively.
Description
Technical field
The vehicle-mounted ultrasonic sensor of the present invention belongs to sensor field.
Background technology
Present vehicle-mounted ultrasonic sensor is when being used for auxiliary parking system or reverse radar system, generally need to adopt various location structures that ultrasonic sensor is fixed on the vehicle body, wherein using metal clips is a kind of common fixed form, vehicle-mounted ultrasonic sensor comprises sensor probe, rubber ring, the sensor cover, sensor glue shell, metal clips, electric leads, pcb board, signal wire and encapsulating material are formed (as shown in Figure 1), rubber ring is enclosed within on the sensor probe, rubber ring is installed in sensor cover and the glue shell, and metal clips is installed on the sensor glue shell.This structure rubber circle, sensor glue shell and metal clips are separated from each other, and they combine by the cooperation of structure, jointly sensor probe are played a protective role (as shown in Figure 2).But in actual use, this structure has the defective of following several aspects:
1, because glue shell and metal clips are to cooperate to be assembled together, combination between the two is also insecure, therefore in the vehicle operating process, can produce vibration and friction, the noise that this vibration and friction produced can pass to sensor probe, thereby influence the detection sensitivity of sensor probe, when situation is serious even can cause the wrong report of signal.
2, owing to be subjected to the influence of product assembly space, the thickness of rubber ring is restricted, make the thinner thickness of rubber ring, the vibration damping and the damping of rubber ring have been weakened, make extraneous undesired signal more easily pass to sensor probe, thereby influence the reliability and the sensitivity of sensor by rubber ring.
3, sensor glue shell, rubber sleeve and metal clips need closely cooperate, and the assembling difficulty has reduced production efficiency of products.
Summary of the invention
The objective of the invention is to avoid the deficiencies in the prior art part, provide a kind of simple in structure, anti-vibration performance is better, the vehicle-mounted ultrasonic sensor that antijamming capability is strong.
The objective of the invention is to reach by following measure, vehicle-mounted ultrasonic sensor is made up of sensor probe, rubber combined cover and end cap, sensor probe is installed in rubber combined putting, and end cap is installed in rubber combined putting, and rubber combined cover is provided with locator card.Rubber combined cover is as a whole, rubber combined cover improves effectiveness in vibration suppression, improves the antijamming capability of sensor probe, efficiently solves friction and vibration problem between the multicompartment cooperation, lowered the influence of structure problem, the sensitivity that has improved product to properties of product.
Rubber combined cover of the present invention is the composite monolithic of rubber sleeve body and metal clips, and metal clips is compounded in the rubber sleeve body one-body molded, and the outside surface at the rubber sleeve body is stretched out at the both ends of metal clips.The rubber sleeve body can improve the antijamming capability of effectiveness in vibration suppression and sensor probe, and metal clips has fixedly solved friction and the vibration problem between the multicompartment cooperation.
The rubber combined locator card that puts setting of the present invention is the boss on rubber combined cover outside surface.
The rubber combined locator card that puts setting of the present invention is the draw-in groove on rubber combined cover outside surface.
The rubber combined locator card that puts setting of the present invention is a metal clips, and metal clips is arranged in the rubber combined cover, and the outside surface at rubber combined cover is stretched out in the end of metal clips.Rubber combined cover is compound as a whole metal clips and rubber sleeve, and has increased the bottom, thereby has replaced original rubber sleeve, metal clips and three accessories of sensor glue shell, has improved the efficiency of assembling of product.Advance in the rubber sleeve owing to the metal clips quilt is directly compound, and cancelled sensor glue shell, therefore not only make the thickness of rubber sleeve be increased, improved the damping capacity of rubber sleeve, also solve simultaneously the friction problem between metal clips and the glue shell, thereby improved the sensitivity and the reliability of sensor.
The rubber combined cover of the present invention is provided with standing block hole, and locator card is inserted in the standing block hole.
The rubber combined cover of the present invention is provided with locating groove, and locator card is inserted in the locating groove.
The present invention is simple in structure, has improved the antijamming capability and the sensitivity of vehicle-mounted ultrasonic sensor, has effectively improved production efficiency of products.
