A heat dissipation mechanism 3 is installed at the middle of the top end of the outer wall of the vehicle body 1. The heat dissipation mechanism 3 is used to dissipate heat generated during equipment operation. The cleaning mechanism 2 includes a support frame 201, which is fixedly connected to the middle of the front side of the outer wall of the cab 16. The middle of the inner wall of the support frame 201... A binocular camera 203 (SD-3DVISION-40) is fixedly connected. A lidar 202 (3D lidar 202HAP(TX)) is mounted on the top of the outer wall of the binocular camera 203. Multiple connecting holes 209 are formed in the middle of the front side of the outer wall of the support frame 201.

Specifically, during equipment operation, the LiDAR 202 and the binocular camera 203 are activated synchronously to perform real-time detection of the road environment in front of the equipment. A protective shell 210 is fixedly installed at the front of the equipment, with the LiDAR 202 embedded inside. The protective shell 210 provides structural support to keep the LiDAR 202 in a stable position, while also protecting it from external impacts. The binocular camera 203 communicates with the external environment through a connecting hole 209 on its body, acquiring road image signals through the hole. A lens 205 shields the camera, preventing dust and debris from directly contacting and damaging it. In rainy conditions, the lens 205... The surface is prone to condensation. At this time, the heating wire 204 is energized and heats up, which is transferred to the lens 205 to evaporate the surface moisture, ensuring that the image captured by the binocular camera 203 remains clear. At the same time, the motor 208 starts running. The output end of the motor 208 rotates, driving the connecting rod 207 to rotate. The non-woven fabric 206 connected to the other end of the connecting rod 207 moves synchronously with the connecting rod 207. The non-woven fabric 206 contacts the surface of the lens 205 and wipes it, removing stains from the lens 205 and keeping the lens 205 clean.

Doors 9 are rotatably connected to the left and right sides of the outer wall of cab 16. A handle 8 is fixedly connected to the middle left side of the outer wall of door 9. Specifically, the road environment signals collected by the lidar 202 and the binocular camera 203 are transmitted to the switch 306 via a preset line, where the switch 306 analyzes and processes the signals. During the operation of the switch 306, the internal components generate heat. At this time, the fan at the air inlet 302 starts, drawing in external cold air into the housing 301 through the air inlet 302. The cold air absorbs heat as it flows over the surface of the switch 306, cooling the switch 306. Simultaneously, the exhaust structure at the air outlet 303 starts, expelling the hot air absorbed by the housing 301 to the outside, forming an air circulation to achieve heat dissipation. When in rainy conditions, the housing 301... The top rainproof roof 304 adopts a sloping structure design. After rainwater falls on the surface of the rainproof roof 304, it slides down quickly along the sloping surface, preventing rainwater from flowing back into the interior of the outer shell 301 through the air inlet 302 and the air outlet 303. When installing the outer shell 301, first align the buckle 309 on the back of the outer shell 301 with the slot 310 on the outer wall of the vehicle body 1, and insert the buckle 309 into the slot 310 to achieve the initial positioning of the outer shell 301 and the vehicle body 1. Then take the nut 308, put the nut 308 into the outer wall of the threaded rod 307, and turn the nut 308. The tightening force generated by the thread engagement between the nut 308 and the threaded rod 307 makes the outer shell 301 stably fixed to the outer wall of the vehicle body 1.

[0021] Working principle: When the equipment is running, the lidar 202 and the binocular camera 203 start to detect the road ahead. The protective shell 210 supports the lidar 202 and prevents it from being damaged. The binocular camera 203 collects signals outward through the connecting hole 209. The lens 205 prevents the camera of the binocular camera 203 from being damaged. In rainy weather, the heating wire 204 is activated to heat the water vapor in the lens 205, so that the image collected by the binocular camera 203 is clear. At the same time, the motor 208 starts and its output end drives the connecting rod 207 to rotate, so that the non-woven cloth 206 can wipe the lens 205 to keep the lens 205 clean. The support frame 201 protects the binocular camera 203 from water vapor seepage. The signals collected by the lidar 202 and the binocular camera 203 are transmitted to the switch 306 for processing. When the switch 306 is running, it generates heat and activates the air inlet 302 to draw in outside air to cool the switch 306. At the same time, the air outlet 303 exhausts the hot air inside the housing 301. The sloped design of the rainproof roof 304 prevents rainwater from flowing back in during rainy weather. When installing the housing 301, the buckle 309 is inserted into the slot 310 and then the nut 308 is screwed into the outer wall of the threaded rod 307 to fix the housing 301 to the outer wall of the vehicle body 1.
