Collision plate assembly and self-moving robot

Abstract

The invention provides a collision plate assembly and a self-moving robot. The collision plate assembly is fixed to a target object, and the collision plate assembly comprises a collision plate body, a triggering mechanism configured to trigger to send a motion stopping signal to the target object under the condition that the collision plate body is collided and moves to enter a first stroke, and a buffering mechanism configured to perform elastic buffering on the collision plate body under the condition that the collision plate body further displaces to enter a second stroke. According to the collision plate assembly, through arrangement of double strokes, the triggering mechanism can be easily triggered in a short stroke under the condition of encountering an obstacle, the target object can be fed back to stop moving in time, and then the collision force caused by inertia and the braking distance after the target object stops moving can be effectively reduced through elastic buffering in the second stroke, so that the safety and the practicability of the target object are greatly improved. In addition, the control is simple, the use efficiency is high, and the target object can easily complete work in a scene where collision easily occurs.

Description

technical field [0001] The present application relates to the technical field of intelligent robots, in particular to a collision plate assembly and a self-moving robot. Background technique [0002] With the development of technology and the rise of labor costs, more and more public places (shopping malls, hotels, office buildings, airports, etc.) are gradually using intelligent cleaning robots to clean the ground. However, because public places require machines to clean a large area at a time, cleaning robots generally weigh more than 30kg when a single fresh water tank is fully loaded, and when the cleaning speed is 0.5m / s, the instantaneous impact force can reach more than 200N, which is very important for smart robots. The safety requirements for the operation of cleaning robots are particularly high. [0003] At present, the strike stroke of intelligent cleaning robots on the market is generally within 10mm, and the ratio K of the rebound force to the stroke of the st...

Problems solved by technology

If the design value of the springback force F of the collision board is smaller, the impact force of the cleaning robot on the obstacle will be minimally buffered after the collision board is triggered; if the design value of the rebound force F of the collision board is larger, the collision board will become difficult to
