Description

Technical Field

[0001] The utility model relates to the technical field of vehicle ultrasonic radar equipment, in particular to an assembly structure of a vehicle-mounted ultrasonic radar. Background Art

[0002] In the current automobile market, the use of vehicle-mounted ultrasonic radar has become very common. Ultrasonic radar not only makes parking more convenient, but also reduces the probability of the car hitting obstacles during driving, and can better protect the car.

[0003] Vehicle-mounted ultrasonic radar products are generally composed of two parts: a probe core and a shell. The probe core is responsible for sending and receiving ultrasonic waves to detect objects, and the shell is responsible for carrying and installing the probe core and a PCB board responsible for signal processing. For example, patent CN217954743U provides a vehicle-mounted ultrasonic radar, including a shell with an opening at one end, a probe core assembled in the opening of the shell to transmit and receive ultrasonic waves, and a PCB board assembled in the shell and electrically connected to the probe core to control the working state of the probe core. The probe core is fixed to the shell through a connecting tube, an inner bushing, an outer sheath and other structures, and is firmly assembled.

[0004] However, since the probe core, connecting tube and other structures of the vehicle-mounted ultrasonic radar are all cylindrical, the lack of a reliable limiting structure after assembly makes it easy for the probe core to rotate in the shell during use and installation, causing the connection between the probe core and the PCB board to fail. In addition, the outer sheath that fixes the probe core is inserted into the jack of the connecting tube by a pin and fixed together. Although the connection between the two is firm, it is very difficult to disassemble. When a connection failure occurs between the probe core and the PCB board, it cannot be disassembled for maintenance, which is inconvenient to use. Summary of the invention

[0005] In order to solve the problems in the prior art, this utility model patent designs a vehicle-mounted ultrasonic radar assembly structure to solve the problem that the existing vehicle-mounted ultrasonic radar installation structure lacks a limiting mechanism and is inconvenient to disassemble.

[0006] The technical solution adopted by the utility model is: the ultrasonic radar assembly structure includes an upper cover, a probe core and a main shell, the probe core is fixed to the main shell by the upper cover, the top of the upper cover extends radially inward to form an annular blocking body, the inner side of the upper cover is a circular rectangular inner limit hole, the bottom of the probe core is provided with a circular rectangular limit base, and the limit base is snap-connected to the inner limit hole on the inner side of the upper cover.

[0007] Furthermore, a limiting pad is provided at the bottom of the probe core, a threading hole is opened in the center of the limiting pad, and a rectangular inner limiting groove is opened on the inner side of the limiting pad. The size of the inner limiting groove is the same as the outer shape of the limiting base at the bottom of the probe core. The outer shape of the limiting pad is also rectangular, the same as the size of the inner limiting hole of the upper cover, the limiting base of the probe core is engaged in the inner limiting groove of the limiting pad, and the limiting pad is engaged in the inner limiting hole of the upper cover.

[0008] Furthermore, a sealing rubber ring is provided on the outer periphery of the limiting pad.

[0009] Furthermore, four claws extend axially from the bottom end of the upper cover, and the four claws are evenly distributed along the circumference of the upper cover, forming engaging protrusions inward respectively. Correspondingly, four slots are respectively opened on the main shell corresponding to the positions of the four claws of the upper cover, and the four slots are respectively formed with radial engaging holes. The four claws at the bottom end of the upper cover are respectively inserted into the four slots of the main shell, and the engaging protrusions on the inner sides of the claws are engaged in the engaging holes of the slots.

[0010] Furthermore, a positioning protrusion is axially extended from the bottom end of the upper cover, and correspondingly, a positioning groove is opened on the main shell at a position corresponding to the positioning protrusion of the upper cover, and the positioning protrusion is inserted into the positioning groove after the upper cover is snap-fitted and fixed to the main shell.

[0011] Furthermore, two positioning protrusions are arranged on both sides of one of the claws at the bottom end of the upper cover, and two positioning grooves are correspondingly arranged on the main shell.

[0012] Compared with the prior art, the advancement of the vehicle-mounted ultrasonic radar assembly structure designed by the utility model patent is:

[0013] A rectangular limiting base is arranged at the bottom of the probe core, and a rectangular inner limiting groove is opened inside the upper cover. The probe core is installed in the inner limiting groove of the upper cover through a limiting pad. After installation and fixation, the cooperation of the limiting base, the limiting pad and the inner limiting groove prevents the probe core from rotating, thereby maintaining the stability of its installation position.

[0014] The bottom of the upper cover is fixed to the main shell by four claws. After being connected and fixed, the claws are exposed in the slots of the main shell, making it easy to pry it open and making the removal of the upper cover more convenient.

[0015] The bottom end of the upper cover is provided with a positioning protrusion, which cooperates with the positioning groove on the main shell to ensure that the upper cover and the main shell are accurately aligned during installation, thereby ensuring accurate installation and alignment of the probe core.

[0022] like Figures 1 to 4 As shown, the utility model patent designs an embodiment of a vehicle-mounted ultrasonic radar assembly structure. In this embodiment, the vehicle-mounted ultrasonic radar assembly structure includes an upper cover 1, a probe core 2 and a main shell 4. The probe core 2 is fixed to the main shell 4 by snapping the upper cover 1.

[0023] The upper cover 1 is a cylindrical tubular structure. The top of the upper cover 1 radially extends inward to form an annular stopper 14, the inner side of which is a rectangular inner limit hole 11. Four claws 12 extend axially from the bottom end of the upper cover 1. The four claws 12 are evenly distributed along the circumference of the upper cover 1 and each has a locking protrusion formed inward. In addition, two positioning protrusions 13 extend axially from the bottom end of the upper cover 1 on both sides of one of the claws 12.

[0024] The probe core 2 is cylindrical, and its diameter is the same as the inner diameter of the blocking body 14 of the upper cover 1, and it can pass through the blocking body 14. A rectangular limiting base 21 is provided at the bottom of the probe core 2, and wing plates are respectively extended outward at both ends of the limiting base 21. The limiting base 21 at the bottom of the probe core 2 is snap-fitted and embedded in the limiting pad 3. A threading hole is opened in the middle of the limiting pad 3, and an inner limiting groove 31 is opened on the inner side. The inner limiting groove 31 is rectangular, and its size is the same as the outer shape of the limiting base 21 of the probe core 2. The limiting base 21 is embedded in the inner limiting groove 31. The outer shape of the limiting pad 3 is also rectangular, and its size is the same as the size of the inner limiting hole 11 of the upper cover 1. A circle of sealing rubber ring 32 is wrapped around the outer periphery of the limiting pad 3. The limiting pad 3 is embedded and fixed in the inner limiting hole 11 of the upper cover 1, and is sealed by the sealing rubber ring 32.

[0025] A cylindrical mounting platform 41 is integrally protruded on the top of the main housing 4, and the diameter of the mounting platform 41 is the same as the outer diameter of the upper cover 1. Four slots 42 are evenly distributed on the outer circumference of the mounting platform 41 at the positions corresponding to the four claws 12 of the upper cover 1, and each slot 42 has an opening concave in the radial direction.
