The utility model provides a damping device 100 for clean robot 1000 of sweeping the floor to the commercial place carries out the shock attenuation, aims at solving the poor problem of clean robot 1000 shock attenuation effect of sweeping the floor that is applied to the commercial place at present. The specific structure of the shock absorbing device 100 of the present invention will be explained;

as shown in fig. 1 to 3, in an embodiment of the shock absorbing device 100 of the present invention, the shock absorbing device 100 includes a chassis 10, a bracket 20 and a roller 30, the chassis 10 is provided with a mounting surface 11, the bracket 20 is telescopically mounted on the mounting surface 11 along a normal direction of the mounting surface 11, the roller 30 is rotatably mounted on the bracket 20, and a periphery of the roller 30 at least partially penetrates through the chassis 10.

The following description will be made by taking as an example the application of the damping device 100 to uneven level ground:

specifically, the roller 30 contacts with the ground, the bracket 20 is mounted on the upper surface of the chassis 10 and can extend and retract along the upper surface of the chassis 10, when the roller 30 is impacted by an impact force deviating from the ground during a compression process, the roller 30 pushes the bracket 20 to move the bracket 20 upward, and when the roller 30 is impacted by an impact force facing the ground during an extension process, the roller 30 drives the bracket 20 to move the bracket 20 downward.

Alternatively, the bracket 20 may be mounted on the lower surface of the chassis 10, and the bracket 20 may also be extended and contracted along the lower surface of the chassis 10 to achieve a shock-absorbing effect.

Therefore, it can be understood that, in the technical solution of this embodiment, when the roller 30 rolls on the uneven bottom surface or other surfaces, the roller 30 receives a certain impact force, and the bracket 20 drives the roller 30 to extend and retract along the normal direction of the mounting surface 11, so as to buffer the certain impact force, thereby effectively improving the damping and buffering effects of the roller 30 when the sweeping cleaning robot 1000 applied to the commercial place encounters the uneven ground or collides with an obstacle during the operation process, and solving the problem that the damping effect of the sweeping cleaning robot 1000 applied to the commercial place at present is poor.

In the present embodiment, the side of the roller 30 facing the ground is protruded from the chassis 102 cm. Since the buffer space of the roller 30 is limited and it is difficult to pass through a high obstacle if the protruding distance is too small, the roller 30 is not stably mounted to the bracket 20 if the protruding distance is too large, and a deviation or the like is easily generated during the operation.
