This application makes the emission direction of the detection beam and the incident direction of the echo beam approximately parallel, without the need to turn the beam, and the structural arrangement of each optical device is relatively simple, reducing or avoiding alignment of the optical path.

[0039] Through the structural design of the protection mechanism, when the laser radar body 1 is not working, the first protection plate 33 and the second protection plate 40 above the laser radar body 1 will rotate to the bottom of the laser radar body 1 and form a complete protective shell with the fixed shell 22 to protect the laser radar body 1 and separate the laser radar body 1 from the outside world to reduce the adhesion of dust and dirt on the surface of the laser radar body 1, thereby reducing the number of times the laser radar body 1 needs to be cleaned regularly, so that the laser radar body 1 can work for a long time. Two groups of mounting blocks 21 are fixed on the rear end of the fixed shell 22. The mounting blocks 21 are fixed to the mounting shell 20 by screws to facilitate the installation and disassembly of the fixed shell 22. The servo motor 25 is fixed in the mounting groove 24.

When working, the servo motor 25 first drives the driving gear 26 to rotate, and the driving gear 26 is meshed with the outer fixing ring 27 and the inner fixing ring 36. The inner wall of the outer fixing ring 27 and the outer side of the inner fixing ring 36 are provided with teeth so that they can be smoothly driven by the driving gear 26, and the outer fixing ring 27 and the inner fixing ring 36 are staggered with each other.

The first baffle plate 28 and the second baffle plate 43 are made of transparent material. To ensure that the laser emitted by the laser radar body 1 can pass through smoothly, at the same time, the first baffle plate 28 and the second baffle plate 43 can also protect the laser radar body 1 when it is working to reduce the adhesion and accumulation of dust and dirt on the laser radar body 1 during work.

[0040] Further, the cleaning mechanism includes a rotating rod 47, the rotating rod 47 is fixedly connected to the driving gear 26, the front end of the rotating rod 47 is fixedly connected to the driving gear 55, the driving gear 55 is rotatably connected to the inner side of the end cover 23, the driving gear 55 is meshed with a gear ring 51, the outer side of the gear ring 51 is rotatably connected to the inner wall of the end cover 23, the left and right sides of the inner wall of the gear ring 51 are meshed with the driven gear 49, the front end of the driven gear 49 is fixedly connected to a rotating column 52, the rotating column 52 is rotatably connected to the end cover 23, and the rear end of the driven gear 49 is inserted with a brush roller 50;

[0041] Through the structural design of the cleaning mechanism, the dust and dirt on the surface of the first baffle plate 28 and the second baffle plate 43 can be cleaned in time to ensure that the dust and dirt attached to the surface of the first baffle plate 28 and the second baffle plate 43 can be cleaned in time, so that when the laser radar body 1 is working, the surface of the first baffle plate 28 and the second baffle plate 43 can be kept clean to avoid interference with the normal operation of the laser radar body 1.

When working, the first through groove 32 is provided on the first protective plate 33 and the second protective plate 40, and the second through groove 54 is provided on the left and right sides of the fixed shell 22. When the first protective plate 33 and the second protective plate 40 are rotated downward to the maximum angle, the first through groove 32 will be aligned with the second through groove 54. The second through slot 54 is arranged close to the brush roller 50, and a rotating plate 53 is arranged on the second through slot 54 to clean the brush roller 50. The rotating plate 53 is used to close the second through slot 54 to reduce the entry of dust and other debris from the outside into the fixed shell 22 through the second through slot 54. The first through slot 32 will be connected to the second through slot 54 only when the first protective plate 33 and the second protective plate 40 are rotated downward to the maximum angle. When the first protective plate 33 and the second protective plate 40 are located above the laser radar body 1, the outer sides of the first protective plate 33 and the second protective plate 40 will block the second through slot 54.

[0045] When working, the cross-section of the connecting plate 39 is designed in a Z shape and a long groove 31 is opened on the fixing frame 30. The opening of the long groove 31 allows the connecting plate 39 connected to the second protective plate 40 to pass through the long groove 31 smoothly during the rotation of the second protective plate 40, thereby avoiding interference with the fixing frame 30, thereby ensuring that the first shielding plate 28 and the second protective plate 40 can rotate normally. The design of the trapezoidal block 29 and the trapezoidal groove 37 can improve the connection strength between the fixing frame 30 and the inner fixing ring 36, so that the first shielding plate 28 will not shake greatly when rotating.

[0046] Furthermore, the cross section of the fixing frame 30 is L-shaped, and the fixing frame 30 contacts the inner wall of the groove 38, and the groove 38 is opened at the rear end of the second protective plate 40;

[0047] During operation, the cross section of the fixing frame 30 is L-shaped and its size matches the groove 38 , so that the fixing frame 30 can smoothly pass through the groove 38 during rotation, avoiding contact with the second protective plate 40 , and ensuring that the fixing frame 30 can rotate normally.

[0049] During operation, the bottom end portion of the brush roller 50 contacts the sealing plate 44, and the sealing plate 44 is used to seal the area between the top of the first baffle plate 28 and the bottom of the second protective plate 40, as well as the top of the second baffle plate 43 and the bottom of the first protective plate 33, to reduce the entry of external dust and dirt into the interior of the fixed shell 22 and the attachment to the bottom end of the brush roller 50. The sealing plate 44 is fixed on the extension plate 34, and the extension plate 34 is fixed on the bottom ends of the first protective plate 33 and the second protective plate 40. Since the long groove 31 is provided on the fixing frame 30, the upward rotation angle of the first baffle plate 28 is limited, and the downward rotation angle of the first protective plate 33 and the second protective plate 40 is limited. At this time, the problem that the bottom ends of the first protective plate 33 and the second protective plate 40 cannot be closed can be solved by the extension plate 34.

[0050] Furthermore, a slope 45 is provided on the bottom end of the extension plate 34, and four groups of conical holes 46 are provided on the slope 45, and a groove 38 is provided at the rear end of one group of the extension plates 34;
