In the prior art, as shown in fig. 1 and 2, a spring device for front collision of a mobile robot adopts a spring plate structure to reset and rebound when colliding with an obstacle, and the spring plate structure is easy to deform and lose efficacy due to long elastic stroke of the spring plate after being used for a long time. Especially, when the mobile robot is non-circular, such as a D-shaped mobile robot, the phenomenon of failure and deformation is more likely to occur after long-term use due to uneven stress. And because the coverage area of the elastic sheet structure is larger, the design is not flexible, and the area of the elastic sheet structure cannot be freely distributed.
Therefore, it is an urgent need in the art to design a mobile robot front collision spring device that can flexibly arrange an elastic region and improve the service life of the spring device structure.

Detailed Description
In order to more fully understand the technical content of the present invention, the present invention will be further described with reference to the accompanying drawings, but not limited thereto.
As shown in fig. 4, the mobile robot front collision spring device provided by the utility model comprises a main body 1 and a movable mechanical front collision 2 connected to the main body 1, wherein at least one spring device 3 is arranged on the main body 1, so that the mechanical front collision 2 can return to rebound after colliding with an obstacle. The main body 1 of the utility model is a cleaning robot, such as a sweeping robot, a mopping robot or a sweeping and mopping integrated robot. But is not limited thereto and may be other mobile robots such as AGVs, etc. In the utility model, the main body 1 of the mobile robot is D-shaped, and the mechanical front collision 2 is provided with four spring devices 3 which are respectively arranged at two sides and two front ends, but the utility model is not limited to the above, and can also be arranged freely, such as four front sections of the mechanical front collision 2.
Referring to fig. 3 and 4, in an embodiment of the present invention, a cavity 101 is disposed on the main body 1. The spring means 3 is tightly fitted in the chamber 101.
In an embodiment of the present invention, as shown in fig. 3 and 4, the spring device 3 includes: a spring 301. A top column 302, wherein the top column 302 is tightly embedded in the spring 301. The top pillar 302 of the present invention is in the shape of a hemispherical cap, so that the top pillar 302 and the mechanical front collision 2 are in point-to-point contact, but the present invention is not limited thereto, and the top pillar 302 may have other shapes, such as a column shape. It should be understood that one end of the spring 301 contacts the cavity 101 of the main body 1 and generates a supporting function, and the other end of the spring 301 is engaged with and pressed against the top pillar 302, so that when the spring device 3 is pressed by an external force, the spring 301 can be compressed, and when the spring device is not pressed by the external force, the spring 301 automatically rebounds and resets.
