[0020] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0021] like Figures 1 to 3 As shown, this embodiment discloses a small lidar anti-collision buffer device, including a frame 1, an inner buffer structure 2 in the frame 1, and a lidar 6 installed on the inner buffer structure 2. The frame 1 is formed by bending a thickened structural steel plate, which provides a fixed position for the inner buffer structure 2 and protects the lidar 6 from impact.
[0022] A protective cover 3 is installed on the top of the frame 1. Multiple spaced outer buffer modules 4 are arranged around the protective cover 3. The outer buffer modules 4 pass through the reserved holes on the protective cover 3 and are connected to the frame 1. The protective cover 3 is formed by bending structural steel plate and is connected to the frame 1 by screws. The protective cover 3 mainly provides support and guidance for the outer buffer modules 4, and also provides secondary protection for the lidar 6. The outer buffer modules 4 are distributed in multiple directions and angles, and are the main anti-collision buffer structure.
[0023] In this embodiment, frame 1 is a hexagonal barrel-shaped structure formed by bending steel plates. Frame 1 provides a fixed position for the inner buffer structure 2, provides installation space for the lidar, and protects the lidar 6 from impacts.
[0024] In this embodiment, the inner buffer structure 2 includes a lidar fixing plate 201. The lidar fixing plate 201 is connected to the inner wall of the frame 1 through four first elastic members 202 arranged on both sides. The lidar 6 is installed on the lidar fixing plate 201.
[0025] The first elastic element 202 can be a spring made of high-strength alloy. Seat plates are welded to both ends of the spring, and these seats are bolted to the inner walls of the lidar mounting plate 201 and the frame 1. While maintaining the stability of the lidar 6, the inner buffer structure 2 can also absorb some of the impact force through the high-strength alloy buffer spring when subjected to an impact, ensuring that the lidar 6 is not damaged.
[0026] In this embodiment, the outer buffer module 4 includes a crash block 401, which is slidably connected to a pre-drilled hole in the side wall of the protective cover 3. The inner surface of the crash block 401 is connected to the outer wall of the frame 1 through a second elastic element 402. The outer buffer module 4 mainly deals with direct impacts from external objects, greatly reducing the impact force of direct impacts.
[0027] The second elastic element 402 can be a spring made of high-strength alloy material. Seat plates are welded to both ends of the spring, and the seat plates are fixed to the outer wall of the anti-collision block 401 and the frame 1 by bolts. The anti-collision block 401 can be made of rubber.
[0028] In this embodiment, the lidar 6 is installed at the bottom of the lidar mounting plate 201. A bottom protective plate 5 is provided below the lidar 6, parallel to the frame 1. One side of the bottom protective plate 5 is connected to the frame 1 via a connecting plate 501. The gap between the bottom protective plate 5 and the frame 1 facilitates the lidar 6 to emit detection signals.
[0029] In this embodiment, as Figure 1 and 4 The connecting plate 501 is designed with mounting holes 502, which are installed on the fixed object by bolt assembly.
[0030] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
