After the cleaning robot exits from the low area, the front collision shell 2 will be lifted and reset under the action of the elastic floating component 3. Further, when the front collision shell 2 collides with the low area, the first limiting component 103 and the second limiting component 103 cooperate to limit the distance of the front collision shell 2 to move in the up and down directions and in the horizontal direction, so that the front collision shell can move in a certain up and down direction and in the horizontal direction when colliding with the low area, while avoiding the front collision shell 2 from being disconnected from the robot body 1, and further preventing the occurrence of hard collision. Optionally, the front collision shell 2 is arc-shaped.

[0039] In one embodiment, an elastic pushing sheet 6 is provided on one side of the robot body 1 close to the front collision shell 2, and the elastic pushing sheet 6 acts on the front collision shell 2 to push it away from the robot body 1. Furthermore, a sensing swing arm is provided on the front side of the robot body 1, and the sensing swing arm includes a rebound swing arm 701 and a sensor (not shown in the figure) triggered by the front collision shell 2 squeezing the rebound swing arm 701. In this embodiment, by providing an elastic pushing sheet 6 to push the front collision shell 2 away from the robot body 1, when the utility model does not collide with external objects, a certain preset distance is maintained between the front collision shell 2 and the robot body 1. At this time, the front collision shell 2 will not touch the rebound swing arm 701. When the cleaning robot collides with the top of a low area, due to the robot body The forward momentum of the body 1 will overcome the elastic force of the elastic pushing piece 6, so that the front collision shell 2 will be displaced toward the direction of the robot body 1. At this time, the front collision shell 2 will touch and squeeze the rebound swing arm 701, so that the rebound swing arm 701 triggers the sensor (not shown in the figure).

Furthermore, the rebound swing arm 701 includes a tail end and a head end. The head end of the rebound swing arm 701 extends from the mounting slot 101 to the front side of the robot body 1 so that when the robot body 1 collides, the front collision shell 2 can act on the front end of the rebound swing arm 701 so that the state of the entire rebound swing arm 701 is changed to trigger the sensor. In this embodiment, the limit assembly 103 is a limit plate or a limit column. When the cleaning robot does not collide with external objects, under the action of the torsion spring 101.2, the tail end of the rebound swing arm 701 will act on the limit assembly 103, so as to ensure that the rebound swing arm 701 is in a pre-contact state to facilitate the pre-contact of the rebound swing arm 701 with the front collision shell 2 after the cleaning robot collides.

[0041] In one embodiment, the first limiting component 103 includes an assembly eave 401 arranged on the top of the front collision shell 2 and a first limiting groove 402 arranged on the assembly eave 401, and the second limiting component 103 includes a plurality of limiting blocks 501, and the length, width and height of the limiting blocks 501 are all smaller than the length, width and depth of the first limiting groove 402, so that when the limiting blocks 501 are inserted into the first limiting groove 402, the front collision shell 2 also reserves a distance for up and down displacement and horizontal displacement with the robot body 1. When the cleaning robot collides with external objects, the front collision shell 2 will be displaced up and down and / or left and right relative to the robot body 1. Furthermore, a step groove 403 is arranged at the top edge of the robot body 1, and there are multiple limiting blocks 501 and they are all arranged in the step groove 403.

[0042] In one embodiment, the front collision shell 2 includes an upper shell 201 and a lower shell 202 that are detachably connected, the first limiting component 103 includes a mounting cross plate extending from the lower shell 202 toward one side of the robot body 1 and a second limiting groove 404 arranged on the top of the mounting cross plate, the mounting cross plate is at least partially located below the robot body 1, the second limiting component 103 includes a plurality of plug-ins 502 arranged at the bottom of the robot body 1 and adapted to the second limiting groove, the length, width and height of the plug-in plates 502 are all smaller than the length, width and depth of the second limiting groove 404, further, so that when the plug-in plates 502 are inserted into the second limiting groove 404, the front collision shell 2 also reserves a space for interlocking with the robot body The front collision shell 2 is a distance for the body 1 to move up and down and horizontally. When the cleaning robot does not collide with external objects, the front collision shell 2 will move up and down and / or left and right relative to the robot body 1. Further, under the action of the elastic floating component 3, the front collision shell 2 is lifted upward. At this time, the plug plate 502 contacts the bottom of the second limiting groove 404 to limit the rise of the front collision shell. When the cleaning robot collides with external objects, the front needle shell sinks. When it sinks to a preset height, the limit block contacts the bottom of the first limiting groove to limit the sinking of the front collision shell. The plug plate 502, the second limiting groove 404, the limit block 501 and the first limiting groove 402 cooperate with each other to limit the front collision shell 2 and the robot body 1 to move up and down and horizontally relative to each other.

[0043] Optionally, a socket 801 is provided at the bottom of the upper shell 201, and an insertion strip 802 is provided at the top of the lower shell 202.

Furthermore, the elastic member 301 is an elastic strip or spring in the shape of a hook, which acts on the first support column 302 to make the first support column 302 contact the top of the assembly eaves 401 to lift the front collision shell 2 upward, so that the front collision shell 2 is higher than the robot body 1. When the cleaning robot enters the low area, the front collision shell 2 collides with the top of the low area, so that the front collision shell 2 presses down the elastic member 301, so that the height of the front collision shell 2 is reduced, and it will not be rigidly stuck in the low area. After the robot body 1 leaves the low area, the height of the front collision shell 2 is restored under the action of the elastic member 301.
