Description

Technical Field

[0001] This utility model relates to the field of non-contact slip rings for radar optoelectronic integrated detection devices, and in particular to a non-contact slip ring for radar optoelectronic integrated detection devices. Background Technology

[0002] Radar-electro-optical integrated detection device is a core device in modern national defense and security. By integrating the all-weather detection capability of millimeter-wave radar with the high-precision imaging advantage of photoelectric sensors, it can achieve multi-dimensional perception and accurate identification of targets. In this device, the non-contact slip ring, as a key connecting component between rotating and fixed components, needs to achieve power transmission and signal exchange under 360° continuous rotation. Its performance directly affects the reliability and detection accuracy of the system.

[0003] In existing radar-photoelectric integrated detection devices, non-contact slip rings suffer from several drawbacks during use. Firstly, the internal wiring connections are not sufficiently secure. During prolonged operation or when subjected to vibration and impact, the wiring can easily loosen or even detach, leading to signal transmission interruption or instability. Secondly, the positioning accuracy between the rotating and fixed parts of the slip ring is insufficient. With increasing usage time, the rotating parts are prone to misalignment, reducing the slip ring's lifespan and transmission efficiency. Therefore, solutions to these technical problems are necessary. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a non-contact slip ring for an integrated radar-electro-optical detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a non-contact slip ring for a radar optoelectronic integrated detection device, comprising a fixed plate and a fixed cylinder assembled at the lower end of the fixed plate. The fixed cylinder and the fixed plate have a through hole in the middle, and a main shaft is rotatably mounted in the middle of the fixed cylinder. A positioning mechanism is installed in the middle of the outer wall of the fixed cylinder. The upper and lower ends of the main shaft are connected to wires, and a fixing mechanism and a buckling mechanism are respectively installed at the upper and lower ends of the wires.

[0006] Preferably, the fixing mechanism includes a connecting block fixed around the spindle, a locking block movably engaging one side of the connecting block, and a first telescopic spring installed between the connecting block and the locking block.

[0007] Preferably, the lower end of the spindle is connected to a fixed base, and an extension ring is fixedly connected to the fixed base vertically downward.

[0008] Preferably, the latching mechanism includes a latch hinged to the outside of the extension ring, and one end of the latch is fixedly connected to a limit block at an equal distance from the extension ring.

[0009] Preferably, the positioning mechanism includes fixed blocks fixed to both sides of the middle part of the fixed cylinder, a movable cavity is provided in the fixed block, an abutment block is slidably engaged in the movable cavity, and a second telescopic spring is installed between the abutment block and the fixed block.

[0010] Preferably, the lower end of the abutment block is chamfered, and the fixing cylinder and the fixing plate are fixedly connected by fixing bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of the abutment block and the second telescopic spring, facilitates the tight fit of the fixed cylinder into the mounting holes of different diameters, improving the stability of the non-contact slip ring and thus preventing the rotating parts from easily shifting. Furthermore, through the cooperation of the fixing mechanism and the buckling mechanism, it is easy to fix the wire, improving the efficiency of wire transmission and thus preventing the wire from loosening or even falling off. Ultimately, it solves the problems of signal transmission interruption or unstable connection, as well as the low service life and transmission efficiency of the slip ring.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example: See Figure 1-8 This utility model discloses a non-contact slip ring for a radar optoelectronic integrated detection device, comprising a fixed plate 1 and a fixed cylinder 4 mounted on the lower end of the fixed plate 1. A through hole is provided in the middle of the fixed cylinder 4 and the fixed plate 1, and a main shaft 2 is rotatably mounted in the middle of the fixed cylinder 4. A positioning mechanism is installed in the middle of the outer wall of the fixed cylinder 4. Wires 3 are connected to both the upper and lower ends of the main shaft 2, and a fixing mechanism and a snap-fit ​​mechanism are respectively installed at the upper and lower ends of the wires 3. The fixed cylinder 4 and the main shaft 2 facilitate rotation within the fixed cylinder 4. The fixing mechanism includes a connecting block 10 fixed around the main shaft 2. A snap-fit ​​block 11 is movably snapped onto one side of the connecting block 10, and a first telescopic spring 12 is installed between the connecting block 10 and the snap-fit ​​block 11. The first telescopic spring 12 and the snap-fit ​​block 11 facilitate clamping and fixing the wires 3. A fixed base 6 is connected to the lower end of the main shaft 2, and an extension ring is vertically fixed downwards to the fixed base 6. The snap-fit ​​mechanism is easily installed through the fixed base 6 and the extension ring.

[0024] In this utility model, the buckling mechanism includes a buckle 9 hinged to the outside of the extension ring. One end of the buckle 9 is fixedly connected to a limiting block at an equal distance from the extension ring. The buckle 9 and the limiting block facilitate locking of the lower wire 3. The positioning mechanism includes a fixing block 7 fixed to both sides of the middle part of the fixing cylinder 4. The fixing block 7 has a movable cavity. An abutment block 8 is slidably engaged in the movable cavity. A second telescopic spring 13 is installed between the abutment block 8 and the fixing block 7. The second telescopic spring 13 and the abutment block 8 facilitate accurate positioning during rotation and avoid deviation. The lower end of the abutment block 8 is chamfered. The fixing cylinder 4 and the fixing plate 1 are fixedly connected by fixing bolts 5. The fixing bolts 5 facilitate a firm connection between the fixing cylinder 4 and the fixing plate 1.

[0025] Working Principle: In the use of this utility model, the fixing cylinder 4 and the fixing plate 1 are first connected and fixed by the fixing bolts 5, so that the main shaft 2 can rotate freely in the fixing cylinder 4 to realize the function of transmitting electrical energy and signals. The main shaft 2 and the fixing base 6 are both connected with wires 3, and the upper and lower wires 3 work together using different mechanisms. The upper wire 3 is fixed by the connecting block 10 and the snap-fit ​​block 11, and the snap-fit ​​block 11 is tightly squeezed by the first telescopic spring 12 to achieve a firm fixation. The lower wire 3 is locked by the snap-fit ​​buckle 9 and the limiting block, so as to securely lock the lower wire 3. When the non-contact slip ring is inserted into the mounting hole, the chamfer design of the lower end of the abutment block 8 causes the abutment block 8 to retract into the fixing block 7. Then, the second telescopic spring 13 makes the abutment block 8 fit tightly against the inner wall of the mounting hole, thereby ensuring accurate positioning during rotation and avoiding deviation, thus ensuring the stability of signal transmission.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
