Description

Technical Field

[0001] The present application relates to the technical field of filter mounting structures, and more specifically, to a mounting structure for a laser radar filter. Background Art

[0002] The filter is made of plastic or glass with special dyes added. The red filter only allows red light to pass through. Similarly, the transmittance of the glass is originally similar to that of air, and all colored light can pass through, so it is transparent. However, after being dyed, the molecular structure changes and the refractive index also changes, and the passage of certain colored light changes. For example, a beam of white light passes through a blue filter, and a beam of blue light is emitted, while green and red light are very small, and most of them are absorbed by the filter. In order to be able to install the filter on the lidar, a corresponding mounting structure is required.

[0003] According to the search, it was found that the Chinese patent with announcement number CN218848544U discloses a filter installation structure, which includes a camera, one end of the camera is provided with a connecting mechanism, the camera is connected to the filter through the connecting mechanism, the connecting mechanism includes an internal thread, an internal thread is opened inside one end of the camera, the outer circular surface of the filter is connected to a connecting ring, one end of the connecting ring is connected to an externally threaded sleeve, the surface of the connecting ring is provided with a rectangular through hole, one end of the camera is provided with an annular slide groove, and the inside of the annular slide groove is slidably connected with an arc slider; the application adopts the structural design of the connecting mechanism, first the user holds the connecting ring, aligns the rectangular through hole of the connecting ring with the limit rod, and then inserts the limit rod into the inside of the rectangular through hole. Since the limit rod is perpendicular to the end face of the camera, the externally threaded sleeve is aligned with the internal thread of the camera at this time, and the user does not need to observe the alignment with the naked eye.

[0004] Regarding the above-mentioned related technologies, the applicant believes that the installation and disassembly of the filter through the threaded structure is inefficient and not convenient enough, and the threaded structure is prone to slippage after long-term use, which is not very practical. Therefore, we propose a mounting structure for the lidar filter. Utility Model Content

[0041] By pressing the mounting block 211 downward, the fixing block 222 is pulled out of the slot 215, so that the return spring 224 can shrink. Then, the mounting block 211 is rotated by the protruding column 213 so that the notch 214 can be aligned with the fixing block 222. At this time, the pressure on the mounting block 211 is released, and the return spring 224 will reset and drive the mounting block 211 to rise, so that the fixing block 222 can pass through the notch 214, thereby realizing the disassembly of the mounting block 211 and then the disassembly of the filter body 212.

[0042] The first adjustment component 120 includes two fixed columns 121 respectively fixedly connected to both sides of the radar body 110, and the surfaces of the two fixed columns 121 are rotatably connected to the connection blocks 122, one side of one connection block 122 is fixedly connected to a drive motor 123, and the output end of the drive motor 123 is fixedly connected to one of the fixed columns 121, and a first rectangular plate 124 is fixedly connected between the bottoms of the two connection blocks 122.
