The task of which is to assist or replace human work, such as production, construction, cleaning, or dangerous work.

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.
