[0001] The utility model relates to the technical field of robots, in particular to a joint lubrication component of a humanoid robot. Background Art

[0002] A humanoid robot, also known as a bionic man, is a robot designed to mimic human appearance and behavior, especially one with a human-like body. Advances in robotics have made it possible to design functional, realistic humanoid robots.

[0003] In the prior art, the joint lubrication effect of humanoid robots is poor. When the joint lubricant is insufficient, it is not convenient to remind the staff. Long-term lack of lubricant leads to a reduction in the service life of the joints. Therefore, we have introduced a joint lubrication component for a humanoid robot. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A joint lubrication assembly of a humanoid robot comprises a mounting seat, a cavity is provided inside the mounting seat, a rotating block is rotatably provided in the cavity, and a plurality of spherical grooves are evenly provided on the circumferential wall of the cavity, a ball is rotatably provided in the spherical groove, one side of the ball is slidably connected to the rotating block, an annular cavity is provided inside the mounting seat at the outside of the cavity, a connecting hole is provided between the annular cavity and the spherical groove, an oil injection channel is provided at the top of the annular cavity, an oil injection mechanism is provided at the upper end of the mounting seat at the oil injection channel, an opening is provided on one side of the cavity, an annular plate is fixedly provided at the opening, a mechanical arm is provided inside the annular plate, both ends of the mechanical arm extend to the outside of the annular plate, a driving device is fixedly provided on one side of the mounting seat, and an output end of the driving device is fixedly connected to the rotating block.

[0008] Preferably, the side wall of the rotating wheel is provided with anti-slip grooves.

[0009] Preferably, the spring is always in a compressed state.

[0010] Preferably, the inner side wall of the mounting seat and the side wall of the annular plate are both provided with a second sealing ring.

[0011] Preferably, a pull block is fixedly provided on the upper end of the slide rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The joint lubrication component of the humanoid robot is equipped with a mechanical arm, annular plate, shell, mounting seat, driving device, rotating block, piston, annular cavity, ball, rotating wheel, bolt, sliding rod, pulling block and spring. The bolt is screwed out and lubricating oil is injected into the shell through the oil filling port. The spring pushes the piston, and the piston pushes the lubricating oil.
