Technical Field
[0001] The utility model relates to the technical field of wheeled robots, in particular to a wheeled robot with a shock absorption function. Background Art
[0002] As is well known, a wheeled robot is a mobile robot equipped with wheels, which realizes movement and navigation by the rotation of the wheels. These robots are usually used in indoor or flat ground environments and are widely applied in fields such as automated logistics, service industries, and scientific research. Through the friction between the wheels and the ground, the wheeled robot can move smoothly in different directions and perform tasks such as item handling, cleaning, or data collection. The wheeled design simplifies motion control and is suitable for application scenarios that require high-speed and stable movement.
[0003] However, for traditional wheeled robots, usually when the wheeled robot encounters an obstacle, such as a small stone, a protruding ground, or other obstacles, the wheels will receive an instantaneous impact force, which will cause the robot to vibrate. This vibration will be transmitted to the internal components of the robot, affecting its stability and accuracy. Therefore, there is an urgent need for technical improvement. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a wheeled robot with a shock absorption function. When this wheeled robot is in use, when it encounters an obstacle, the moving wheel drives the mounting frame and the upper sliding rod to move under the action of force. The movement of the sliding rod drives the two sliding sleeves on both sides and the second return spring to be compressed, and cooperates with the damping rod and the shock absorption spring to be compressed. The return spring and the shock absorption spring can effectively absorb the energy generated by the collision, reduce the damage of the impact force to the robot, and cooperate with the damping rod to smooth the vibration during movement and reduce the oscillation of the robot during movement or collision, making the robot recover more smoothly in uneven areas or after collision.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:

Compared with the existing wheeled robots, when this wheeled robot is in use, through a plurality of protective rollers 207, when the outer wall of the robot approaches an obstacle, the protective rollers 207 drive the articulated rod 206 to move under the action of force, and at the same time drive the sliding sleeve one 205 to slide on the outer wall of the fixed rod 203, thereby compressing the first return spring 204. Furthermore, by compressing the first return spring 204, it helps to reduce and relieve the external force, avoiding excessive pressure on the outer shell and internal components of the robot, thereby maintaining the integrity of the structure and having relatively high practical performance.
[0037] Refer to Figure 1 , Figure 3 and Figure 5 , the sliding sleeves one 205 are respectively slidably connected to the outer walls of the fixed rods 203.

[0038] Working principle: When in use, when encountering an obstacle, the moving wheel 308 drives the mounting bracket 307 and the upper sliding rod 306 to move under the action force. The movement of the sliding rod 306 drives the two sliding sleeves 305 on both sides and the return spring 304 to be compressed, and cooperates with the damping rod 312 and the shock-absorbing spring 313 to be compressed. The return spring and the shock-absorbing spring 313 can effectively absorb the energy generated by the collision and reduce the damage to the robot caused by the impact force. Cooperating with the damping rod 312, it can smooth the vibration during movement and reduce the shock of the robot during movement or collision, making the robot more stable when recovering in uneven areas or after collision. When the outer wall of the robot approaches the obstacle through multiple protective rollers 207, the protective rollers 207 drive the articulated rod 206 to move under the action force and at the same time drive the sliding sleeve 205 to slide on the outer wall of the fixed rod 203, thereby compressing the return spring 204. Furthermore, the compression of the return spring 204 helps to reduce and relieve the external force and avoid excessive pressure on the outer shell and internal components of the robot, thereby maintaining the integrity of the structure.
