Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to an ultrasonic radar with a stepped sealing ring. Background Technology
[0002] With the increasing prevalence of safety and intelligent driving functions, ultrasonic radar is a radar sensor device that uses ultrasonic waves to measure distance. It calculates distance by measuring the time difference between the received and transmitted ultrasonic waves, and is used for direction detection and distance measurement. In short-range measurements, ultrasonic radar ranging has significant advantages and is widely used in applications such as parking assistance and automatic parking.
[0003] Currently, the ultrasonic radar is directly bonded to the housing with glue. During transportation and use, friction and vibration between the ultrasonic radar and the housing may damage the ultrasonic probe, thereby reducing the service life of the ultrasonic probe. Utility Model Content
[0004] The purpose of this invention is to provide an ultrasonic radar with a stepped sealing ring, which aims to solve the problem that friction and vibration between the existing ultrasonic radar and the housing may cause damage to the ultrasonic probe.
[0005] To achieve the above objectives, this utility model provides an ultrasonic radar with a stepped sealing ring, including a shell, a support base, two fixing rods, a sealing ring, an ultrasonic radar body, and a protective cap.
[0006] The support base is installed on the outer shell, and the two fixing rods are respectively fixedly connected to the support base and are both located on the support base. The sealing ring is installed inside the support base and abuts against the two fixing rods. The ultrasonic radar body is installed on the sealing ring. The protective cap is snapped into the support base and is located on the side of the support base closer to the ultrasonic radar body.
[0007] The sealing ring has two mating grooves and two stepped rings. The two mating grooves are located on the outside of the sealing ring and abut against the two fixing rods respectively. The two stepped rings are installed on the outside of the sealing ring respectively.
[0008] The support base has a boss, which is fixedly installed inside the support base, and the boss and the support base form a limiting groove.
[0009] The protective cap includes a cap shell, a pressing assembly, and two clamping plates. The cap shell is fitted onto the ultrasonic radar body, the pressing assembly is installed on one side of the cap shell, and both clamping plates are installed on the pressing assembly.
[0010] The pressing assembly includes a transmission block, a pressing head, two driven blocks, and a return spring. The transmission block is slidably connected to the cap shell and is located on the outer shell. The pressing head is fixedly connected to the transmission block. The two driven blocks are slidably connected to the transmission block and to the cap shell, and are fixedly connected to the two clamping plates. The return spring is fixedly connected to the pressing head and to the cap shell, and is located between the pressing head and the cap shell.
[0011] This invention discloses an ultrasonic radar with a stepped sealing ring. The outer shell provides installation conditions for the support base and the sealing ring. The support base provides installation conditions for two fixing rods, which can support the sealing ring. The sealing ring allows the ultrasonic radar body to be mounted on the support base. The protective cap protects the exposed part of the ultrasonic radar body, preventing damage from external forces during transportation. The elastic and flexible sealing ring buffers and absorbs shocks, reducing friction and wear between the ultrasonic radar body and the outer shell, and extending the service life of the ultrasonic radar body. This solves the problem that friction and vibration between the ultrasonic radar and the outer shell can damage the ultrasonic probe in existing ultrasonic radar systems. Attached Figure Description

The sealing ring 4 is installed inside the support base 2 and abuts against the two fixing rods 3. The ultrasonic radar body 5 is installed on the sealing ring 4. The protective cap 6 is snapped into the support base 2 and is located on the side of the support base 2 close to the ultrasonic radar body 5.
[0020] In this embodiment, the outer shell 1 provides installation conditions for the support base 2 and the sealing ring 4. The support base 2 provides installation conditions for the two fixing rods 3. The two fixing rods 3 can support the sealing ring 4. The sealing ring 4 can be used to install the ultrasonic radar body 5 on the support base 2. The protective cap 6 can protect the exposed part of the ultrasonic radar body 5, preventing damage to the ultrasonic radar body 5 from external forces during transportation. The sealing ring 4, being elastic and flexible, can buffer and dampen the ultrasonic radar body 5, reducing friction and wear between the ultrasonic radar body 5 and the outer shell 1, and extending the service life of the ultrasonic radar body 5. This solves the problem that friction and vibration between the ultrasonic radar and the outer shell 1 may damage the ultrasonic probe.
[0021] Furthermore, the sealing ring 4 has two mating grooves 7 and two stepped rings 8. The two mating grooves 7 are located on the outside of the sealing ring 4 and abut against the two fixing rods 3 respectively. The two stepped rings 8 are installed on the outside of the sealing ring 4 respectively.
[0022] In this embodiment, the stability of the sealing ring 4 installed in the support base 2 can be improved by the two fitting grooves 7 and the two fixing rods 3, and the stability of the sealing ring 4 can be further improved by the two stepped rings 8 supporting the support base 2.
