Description

Technical Field

[0001] The utility model is applied to the technical field of laser radar, and particularly relates to a radar component with a lens that is easy to disassemble. Background Art

[0002] The existing laser radar needs to install a telescope device and a focusing lens device inside, and a lens needs to be embedded in front of these two devices on the laser radar shell. The traditional production method is to use glue to embed the lens and fix it on the shell. During long-term use, the coating layer on the surface of the lens is easily damaged, and the lens needs to be disassembled and replaced. The traditional method is to directly pry open and replace or disassemble the shell, remove the telescope device or focusing lens device, and then knock it out directly from the inside. However, both methods will damage the lens, and the cost of the lens is relatively expensive, especially the lens for the telescope device, the required size and thickness are larger than the lens of the focusing lens device. Damage to the lens will undoubtedly increase the cost of use. If a radar component that is easy to disassemble the lens is developed, the lens can be disassembled without damage, the surface of the lens can be re-coated with a film layer, and then put into use again, which can also greatly reduce the production cost. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a radar component which has a reasonable design, saves costs and is convenient for disassembling the lens.

[0004] The technical solution adopted by the utility model is: the utility model includes a radar housing and a cover body adapted to the radar housing, the cover body is provided with a groove, the bottom of the groove is provided with a through hole, a lens is embedded in the groove, the surface of the lens is provided with a film layer, an annular mounting platform is provided inside the cover body and on the outer edge of the back side of the through hole, the annular mounting platform has at least three threaded holes in an annular array, the threaded holes penetrate to the bottom of the groove, and a threaded forward push piece is adapted to be installed in the threaded hole, and the lens can be pushed forward from the groove without damage for replacement by working together with at least three threaded forward push pieces.

[0005] Furthermore, the threaded forward pushing member is a bolt member or a screw member, and a soft cushion head is provided at the front end of the bolt member or the screw member.

[0006] Furthermore, a telescope is installed on the annular mounting platform, the telescope is fixed to the annular mounting platform by bolts, and a first sealing ring is provided between the telescope and the annular mounting platform.

[0007] Furthermore, the threaded hole is a countersunk hole, which includes a first inner groove hole adapted to the bolt member or the screw member and a countersunk hole adapted to the cushion head, and the aperture of the countersunk hole is larger than the aperture of the inner groove hole.

[0008] Furthermore, a mounting seat is provided inside the cover body and at the upper end on the back side of the groove, and a wiper is provided on the mounting seat. The wiper includes a swing motor, a rotating arm, a second sealing ring, a swing arm, and a wiper soft rubber film. The swing motor is fixed on the mounting seat, one end of the rotating arm is connected to the swing motor, and the other end of the rotating arm passes through the cover body and is hinged to the swing arm. The second sealing ring is sleeved on the rotating arm and fixed in the cover body, the wiper soft rubber film is fixed to the swing arm, and the length of the wiper soft rubber film is not less than the aperture of the through hole.

[0009] Furthermore, the cover body is fixed to the radar housing by bolts, and a third sealing ring is provided between the cover body and the radar housing.

[0010] Furthermore, the number of the threaded forward pushers is four.

[0011] The beneficial effect of the utility model is as follows: the utility model has at least three threaded holes in a circular array on the circular mounting platform where the telescope is originally installed. When the film layer of the lens is damaged, the cover body can be removed, and then the telescope can be taken out, and then the soft pad head can be pushed forward by rotating the bolt part or the screw part, and then the soft pad head can give the lens an outward force, and the number of turns of the bolt part or the screw part each time can be controlled to be within 1-3 turns as much as possible, and then the next bolt part or the screw part can be screwed clockwise or counterclockwise in turn, so that the lens can be slowly pushed out of the groove without being damaged, so that the lens can be recycled and re-coated, thereby reducing the use cost of the laser radar.

[0018] like Figures 1 to 6 As shown, in this embodiment, the utility model includes a radar housing 1 and a cover body 2 adapted to the radar housing 1, the cover body 2 is provided with a groove 3, a through hole 4 is provided at the bottom of the groove 3, a lens 5 is embedded in the groove 3, a surface layer of the lens 5 is provided with a film layer, an annular mounting platform 6 is provided inside the cover body 2 and on the outer edge of the back side of the through hole 4, the annular mounting platform 6 has four threaded holes 7 in a circular array, the threaded holes 7 penetrate to the bottom of the groove 3, and a threaded forward push piece is adapted to be installed in the threaded hole 7, and the four threaded forward push pieces can work together to push the lens 5 out of the groove 3 without damage for replacement.

[0019] In the present embodiment, the threaded forward-pushing member is a bolt member or a screw member, and a soft-padded head 8 is provided at the front end of the bolt member or the screw member, and the threaded hole 7 is a countersunk hole, and the countersunk hole includes a first internal groove hole adapted to the bolt member or the screw member and a countersunk hole adapted to the soft-padded head 8, and the aperture of the countersunk hole is larger than the aperture of the internal groove hole, thereby increasing the contact area between the soft-padded head 8 and the lens 5, and when the bolt member or the screw member is rotated and pushed forward, it has a buffering and protective effect on the lens 5, and hard contact is necessary to prevent the lens 5 from being damaged; in this design, the soft-padded head 8 is pushed forward by twisting the bolt member or the screw member, and then the lens 5 attached to the soft-padded head 8 is rhythmically pushed forward from the groove 3 for replacement.

[0020] In this embodiment, a telescope 9 is installed on the annular mounting platform 6 , and the telescope 9 is fixed to the annular mounting platform 6 by bolts, and a first sealing ring 10 is provided between the telescope 9 and the annular mounting platform 6 .

[0021] In this embodiment, a mounting seat 11 is provided inside the cover body 2 and at the upper end on the back side of the groove 3, and a wiper is provided on the mounting seat 11. The wiper includes a swing motor 12, a rotating arm 13, a second sealing ring, a swing arm 14, and a wiper soft film 15. The swing motor 12 is fixed on the mounting seat 11, one end of the rotating arm 13 is connected to the swing motor 12, and the other end of the rotating arm 13 passes through the cover body 2 and is hinged to the swing arm 14. The second sealing ring is sleeved on the rotating arm 13 and fixed in the cover body 2. The wiper soft film 15 is fixed to the swing arm 14, and the length of the wiper soft film 15 is not less than the aperture of the through hole 4. This design makes it easy to clean and sweep the lens 5 with a wiper when it rains outdoors.

[0022] In this embodiment, the cover body 2 is fixed to the radar housing 1 by bolts, and a third sealing ring 16 is provided between the cover body 2 and the radar housing 1 .

[0023] In this embodiment, when the film layer of the lens 5 is damaged during the use of the radar component, when the lens 5 needs to be disassembled and replaced, the cover body 2 is first separated from the radar housing 1, and then the bolts fixing the telescope 9 are screwed to remove the telescope 9. Then the threaded hole 7 on the annular mounting platform 6 can be seen, and then the soft pad head 8 is pushed forward by screwing one of the bolts or screws. The number of turns should not be too many at the beginning to avoid uneven force causing damage to the lens 5. Therefore, it is sufficient to slowly screw 1-2 turns at the beginning, and then the next bolt or screw is screwed 1-2 turns clockwise or counterclockwise in sequence. However, after the four bolts or screws are screwed, the above process is repeated until the lens 5 is completely pushed out of the groove 3, and then a new lens 5 is replaced, and the telescope 9 and the cover body 2 are reassembled. The replaced lens 5 can be recovered and reused for re-coating, which can greatly save the cost of manufacturing the lens 5.

[0024] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
