Description

Technical Field

[0001] This utility model relates to the field of ultrasonic radar, and in particular to an ultrasonic radar PIN and ceramic plate connection structure. Background Technology

[0002] Ultrasonic radar is a sensor that uses a piezoelectric crystal to emit ultrasonic waves through the inverse piezoelectric effect, and then receives the reflected waves and calculates the distance based on the propagation speed and time difference. It is low in cost and highly adaptable to the environment.

[0003] Typically, the pins and ceramic plates of automotive ultrasonic radar products are connected by manual soldering using enameled wire.

[0004] However, manual soldering is costly, and because the PIN is often S-shaped, it can only be fixed to the connecting wire on one side. Due to its special shape, it is often impossible to maintain this state without external support, which is not conducive to automated operation of connecting the PIN and the ceramic plate. Therefore, an ultrasonic radar PIN and ceramic plate connection structure is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a connection structure between an ultrasonic radar PIN and a ceramic sheet, which aims to improve the problem that the shape of the PIN makes it difficult to automate the soldering process in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ultrasonic radar PIN and ceramic sheet connection structure, including a main housing, a ceramic sheet disposed inside the main housing, a PIN mechanism disposed inside the main housing, the PIN mechanism being connected to the ceramic sheet through a fixing mechanism, and the end of the PIN mechanism away from the ceramic sheet being fixedly installed on the inner wall of the main housing;

[0009] The fixing mechanism includes an alloy wire, one end of which is welded to the outer wall of the mounting block, and the other end of which is welded to a connecting ring. The fixing mechanism also includes a connecting seat, the outer wall of which has an insertion port, and the inner wall of which is fixedly connected to a connecting block. The bottom end of the connecting block is fixedly connected to a ceramic sheet.

[0010] As a further description of the above technical solution:

[0011] The fixing mechanism includes a pressure block, the outer wall of which is slidably connected to the inner wall of the connecting seat, a positioning rod that is rotatably connected through the inner wall of the pressure block, a threaded rod that is fixedly connected to the top end of the positioning rod, and the outer wall of the threaded rod that is threadedly connected to the inner wall of the connecting seat.

[0012] As a further description of the above technical solution:

[0013] An insulating block is fixedly connected to the inner wall of the connecting block.

[0014] As a further description of the above technical solution:

[0015] The connecting ring is shaped by connecting a ring and a cuboid, and the inner diameter of the connecting ring is larger than the outer diameter of the positioning rod.

[0016] As a further description of the above technical solution:

[0017] The number of fixing mechanisms is set to two sets. In one set, the lower surface of the connecting block in the fixing mechanism is fixedly connected to the positive electrode of the ceramic sheet, and in the other set, the lower surface of the connecting block in the fixing mechanism is fixedly connected to the negative electrode of the ceramic sheet.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of an ultrasonic radar PIN and ceramic plate connection structure, including a main housing 1, which is the outer shell of the ultrasonic radar. A ceramic plate 2 is disposed inside the main housing 1. A PIN mechanism 3 is disposed inside the main housing 1, and the PIN mechanism 3 has the same function as existing PIN mechanisms. One end of the PIN mechanism 3 away from the ceramic plate 2 is fixedly installed on the inner wall of the main housing 1. The PIN mechanism 3 includes a connecting block 31. A protrusion for fixing the PIN mechanism 3 is disposed inside the main housing 1. The PIN mechanism 3 is inserted into the inner wall of the protrusion. A support strip 32 is fixedly connected to the right side of the connecting block 31. The support strip 32 is not bendable, and its lower end is fixed. A rotating bar 33 is connected, which is bendable and made of nickel-titanium shape memory alloy. A connecting bar 34 is fixedly connected to the lower end of the rotating bar 33. The connecting bar 34 is not bendable. The connecting block 31, the support bar 32 and the connecting bar 34 have the same thickness. By setting the same thickness, it is ensured that the outer surface of the PIN mechanism 3 can fit well with the machine during the automatic welding process, thereby ensuring the automatic welding effect. A rotating bar 35 is fixedly connected to the lower end of the connecting bar 34. The rotating bar 35 is bendable and made of nickel-titanium shape memory alloy. An installation block 36 is fixedly connected to the lower end of the rotating bar 35.

[0034] Reference Figures 3-5 The PIN mechanism 3 and the ceramic plate 2 are connected by a fixing mechanism 4. The fixing mechanism 4 includes an alloy wire 41, which is used to connect the PIN mechanism 3 and the ceramic plate 2. One end of the alloy wire 41 is welded to the outer wall of the mounting block 36. The width of the mounting block 36 is wider than the width of the connecting strip 34. By setting the width, it is ensured that the welding position of the alloy wire 41 is larger. The other end of the alloy wire 41 is welded with a connecting ring 42. The shape of the connecting ring 42 is a ring and a cuboid connected together.

[0035] Reference Figure 1 , Figure 4 and Figure 5The fixing mechanism 4 also includes a connecting seat 48. The outer wall of the connecting seat 48 has a socket 49, the width of which is wider than the outer diameter of the connecting ring 42. A connecting block 43 is fixedly connected to the inner wall of the connecting seat 48. The connecting block 43 is used to connect the ceramic sheet 2 and the alloy wire 41. The fixing mechanism 4 is configured in two sets. In one set of fixing mechanisms 4, the lower surface of the connecting block 43 is fixedly connected to the positive electrode of the ceramic sheet 2, and in the other set of fixing mechanisms 4, the lower surface of the connecting block 43 is fixedly connected to the negative electrode of the ceramic sheet 2. The inner wall of the connecting block 43 is fixedly connected to… An insulating block 47 is attached, and the bottom end of the connecting block 43 is fixedly connected to the ceramic sheet 2. The fixing mechanism 4 includes a pressure block 44, which is used to press the connecting ring 42. The outer wall of the pressure block 44 is slidably connected to the inner wall of the connecting seat 48. A positioning rod 45 is rotatably connected through the inner wall of the pressure block 44. After connection, the positioning rod 45 is set inside the connecting ring 42. The inner diameter of the connecting ring 42 is larger than the outer diameter of the positioning rod 45. A threaded rod 46 is fixedly connected to the top of the positioning rod 45. The outer wall of the threaded rod 46 is threaded through and connected to the inner wall of the connecting seat 48.

[0036] Working principle: When in use, the staff first automatically welds the unbent PIN mechanism 3 to the alloy wire 41 using a machine.

[0037] After the soldering is completed, the workers will bend the rotating strip 33 and the rotating strip 35 of the PIN mechanism 3 according to the required shape, so that the PIN mechanism 3 is consistent with the shape required during installation.

[0038] Subsequently, the staff rotated the threaded rod 46, causing the positioning rod 45 to move upward as it moved upward. When the positioning rod 45 moved to a position where it no longer occupied the space at the height of the socket 49, the staff inserted the connecting ring 42 into the socket 49.

[0039] After insertion, the operator rotates the threaded rod 46 in the opposite direction to the previous rotation direction, causing the threaded rod 46 to move downward during rotation, thereby driving the positioning rod 45 to move downward and enter the interior of the connecting ring 42.

[0040] At the same time, as the threaded rod 46 moves downward, it also drives the pressure block 44 to move downward synchronously. Therefore, the pressure block 44 can contact the upper surface of the connecting ring 42 and press it, so that its lower surface can remain connected to the connecting block 43. At this time, the alloy wire 41 ceramic sheet 2 is fixed. Then, the staff inserts the connecting block 31 into the protrusion inside the main housing 1 to complete the installation.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
