The hydraulic cylinder 301 is engaged with one side of the surface of the body 1, and the floating piston 302 is arranged inside the hydraulic cylinder 301. The compression piston 303 is arranged inside the hydraulic cylinder 301. The spring 304 is fixedly connected to one side of the surface of the hydraulic cylinder 301, and the hydraulic rod 305 is connected to one side of the surface of the compression piston 303. The other end of the hydraulic rod 305 is fixedly connected to the buffer strip 306. Through the arrangement of the hydraulic cylinder 301, the floating piston 302, the compression piston 303, the spring 304, the hydraulic rod 305 and the buffer strip 306, During use, when the bottom of the robot collides with an obstacle while moving, the buffer bar 306 collides with the obstacle to generate vibration, so that the buffer bar 306 squeezes the spring 304 to contract, and at the same time, the vibration is transmitted to the hydraulic rod 305 through the buffer bar 306, so that the hydraulic rod 305 drives the compression piston 303 to squeeze the hydraulic oil inside the hydraulic cylinder 301, and the hydraulic oil squeezes the floating piston 302 to move, and the floating piston 302 squeezes the high-pressure nitrogen at the other end to compress. In this process, the kinetic energy of the vibration is converted into heat energy through the damping effect of the compression piston 303 and the hydraulic oil, and then the heat energy is dissipated through the hydraulic cylinder 301, thereby achieving the effect of shock absorption and buffering, and reducing the damage to the body 1 caused by the collision.

[0021] Furthermore, the hydraulic cylinder 301 is sealed and connected to the hydraulic rod 305, and the spring 304 is sleeved on the surface of the hydraulic rod 305. Through the setting of the hydraulic cylinder 301, when in use, the hydraulic cylinder 301 can store hydraulic oil and high-pressure nitrogen, and at the same time, the hydraulic cylinder 301 can volatilize the heat generated by the damping effect of the hydraulic oil.

[0022] Furthermore, the other end of the spring 304 is fixedly connected to the buffer strip 306, and the buffer strip 306 is provided with four groups. Through the setting of the spring 304, when in use, the spring 304 can buffer the vibration transmitted by the buffer strip 306, thereby avoiding damage to the compression piston 303 due to excessive vibration amplitude.

Through the setting of the compression piston 303, when in use, the compression piston 303 can transmit the vibration power to the hydraulic oil by squeezing the hydraulic oil, so that the compression piston 303 produces a damping effect with the hydraulic oil during the flow of the hydraulic oil.

[0024] Furthermore, the lifting mechanism 4 includes a motor 401, a screw 402, a slider 403, a support rod 404 and a tray 405.

When tray 405 moves to a suitable height, motor 401 stops, thereby achieving the purpose of adjusting the height of tray 405, thereby providing convenience for users of different heights, allowing users to take and put items more comfortably.

[0025] Furthermore, two groups of sliders 403 are provided, and four groups of trays 405 are provided, and the trays 405 are distributed at equal intervals. Through the setting of the sliders 403, when in use, the sliders 403 can provide support for the support rods 404, and at the same time, the movement of the sliders 403 can drive the support rods 404 to move synchronously.

[0026] Working principle: When the bottom of the robot collides with an obstacle while moving, the buffer bar 306 collides with the obstacle to generate vibration, so that the buffer bar 306 squeezes the spring 304 to contract, and at the same time, the vibration is transmitted to the hydraulic rod 305 through the buffer bar 306, so that the hydraulic rod 305 drives the compression piston 303 to squeeze the hydraulic cylinder 301, which contains hydraulic oil. The hydraulic oil squeezes the floating piston 302 to move, and the floating piston 302 squeezes the high-pressure nitrogen at the other end to compress. In this process, the kinetic energy of the vibration is converted into heat energy through the damping effect of the compression piston 303 and the hydraulic oil, and then the heat energy is dissipated through the hydraulic cylinder 301, thereby achieving the effect of shock absorption and buffering, reducing the collision of the body 1 Damage, when the bottom of the robot collides with an obstacle when it moves, the buffer bar 306 collides with the obstacle to generate vibration, so that the buffer bar 306 squeezes the spring 304 to contract, and at the same time, the vibration is transmitted to the hydraulic rod 305 through the buffer bar 306, so that the hydraulic rod 305 drives the compression piston 303 to squeeze the hydraulic cylinder 301, which contains hydraulic oil, and the hydraulic oil squeezes the floating piston 302 to move, and the floating piston 302 squeezes the high-pressure nitrogen at the other end to compress. In this process, the kinetic energy of the vibration is converted into heat energy through the damping effect of the compression piston 303 and the hydraulic oil, and then the heat energy is dissipated through the hydraulic cylinder 301, thereby achieving the effect of shock absorption and buffering, and reducing the damage to the body 1 caused by the collision.
