[0002] A robot is an intelligent machine that can work semi-autonomously or fully autonomously. A robot can perform tasks such as work or movement through programming and automatic control.

[0003] The structure of the existing four-wheel robot lighting transmission mechanism is relatively simple, so that the lighting adjustment result cannot meet the temporary environmental requirements. When the robot walks on a road with many bends at night, the traction wheels will turn first as the robot steering gear adjusts, and then the head can turn. Because the robot lights are installed on both sides of the robot's head, the lighting angle will be adjusted according to the rotation of the head. However, when turning, there are often unknown dangerous situations or objects. In such cases, if the lighting angle is not adjusted in advance, it will cause great economic losses. Therefore, a robot joint transmission mechanism is designed to solve this problem. Utility Model Content

After the linkage rod moves, it can drive the sleeve nail to move, so that the side rod is pushed to slide on the positioning frame, thereby pushing the first bracket to move horizontally in the direction of the lampshade. When the first bracket moves, it drives the special-shaped frame to slide on the outer surface of the cross bar, and at the same time drives the slider to slide in the slide groove.

[0021] Specifically, a through opening 31 is respectively formed on the first bracket 8 and the second bracket 17 , a slide rail 32 is disposed inside the through opening 31 , and a follower block 33 is slidably disposed on both slide rails 32 .

[0022] Specifically, a first bracket 8 and a second bracket 17 are disposed on the upper portion of the supporting steel plate 3 , and a side rod 7 is inserted in the middle of the first bracket 8 and the second bracket 17 , and a spring 19 is sleeved on the outer surface of the side rod 7 .

[0024] Working principle: When the user of the utility model uses this device, the sensor in the robot controls the puller to drive the guide frame 12 to rotate around the rotating rod 4 clockwise, and the rotation of the rotating rod 4 drives the linkage rod 5 to move.

When the robot walks on the ups and downs of the road, the correction lock 22 in the transmission of the lighting light used for the robot driving will correct the lighting angle in time with the bumps of the robot. When the robot's head is facing up, the correction lock 22 will drive the directional shaft 24 to rotate in time. After the directional shaft 24 rotates, it drives the end rod to move, so that the irradiation light of the lighting light 10 is still in a horizontal state. When the end rod moves, it will drive the counterweight column 27 to move in the limiting sleeve 20, and the rubber sleeve 35 protects the counterweight column 27 from colliding with the inside of the limiting sleeve 20.
