As shown in fig. 1 and 2, the present embodiment provides a cleaning robot including a floor mopping robot or a mopping integrated robot. The cleaning robot includes a housing 200, a cleaning mechanism, and a traveling mechanism. Wherein, cleaning mechanism and running gear set up on casing 200, cleaning mechanism is used for cleaning ground, and running gear is used for driving casing 200 motion. The cleaning robot is easy to damage due to collision with obstacles or walls in the working process. The cleaning robot further includes a front striking plate 100 disposed in front of the housing 200, the front striking plate 100 including a main body 1 and two striking flakes 2, the main body 1 being connected with the housing 200, the two striking flakes 2 being disposed at left and right sides of the front striking plate 100, respectively. When the left side and the right side of the front striking plate 100 collide, the elastic deformation of the elastic sheet 2 absorbs the collision force of the front striking plate 100, thereby playing the role of protecting the front striking plate 100.

However, in the prior art, the cleaning robot is in a D shape or a square shape, the front collision plate 100 of the sweeping robot is not easy to realize vertical collision of the side surfaces at the left side and the right side, and the action of the robot spring plate 2 cannot be realized due to the fact that the side surfaces cannot directly collide when the collision occurs in a narrow space, and the front collision plate 100 has poor collision experience and large noise.

Referring to fig. 2, in order to solve the above-mentioned problem, in this embodiment, the main body 1 is provided with a clamping groove 11, the elastic piece 2 is disposed in the clamping groove 11, along the first direction, two sides of the elastic piece 2 are in interference fit with the clamping groove 11, when the main body 1 is impacted by external force, the elastic piece 2 can be elastically deformed, the front striking plate 100 has a simplified structure, and is convenient to assemble, and by using the interference fit of the two sides of the elastic piece 2 and the clamping groove 11, the front striking plate 100 collides with any position left and right and in front, the elastic piece can be triggered to absorb the collision force, and the triggering force required by the front striking plate 100 for triggering the collision is reduced. Specifically, when the left side of the front striker plate 100 collides, the front striker plate 100 moves rightward under the action of an external force, so as to drive the elastic sheet 2 to elastically deform along the first direction, the elastic action of the elastic sheet 2 is utilized to provide buffering for the movement of the front striker plate 100, and the rebound action of the elastic sheet 2 is beneficial to driving the front striker plate 100 to recover to the initial position. Of course, when the right side of the front striker plate 100 collides, the front striker plate 100 moves leftwards under the action of external force and drives the elastic sheet 2 to elastically deform along the first direction, and the elastic deformation of the elastic sheet 2 is also utilized to facilitate the driving of the front striker plate 100 to restore to the initial position.

Illustratively, the clamping groove 11 is disposed at a middle position of the main body 1 along the first direction, and the number of the elastic pieces 2 is one, so that the elastic pieces 2 are located at a middle position of the front impact plate 100, and the elastic forces of the left and right sides are the same when the front impact plate collides.

As an alternative, as shown in fig. 3 and 4, the elastic sheet 2 includes a connection portion 22 and at least two protrusions 21. Wherein, at least two protruding 21 are along first direction interval setting, and protruding 21 is U type structure, and two protruding 21 that lie in head and tail respectively with draw-in groove 11 interference fit, the both ends of connecting portion 22 are connected with the adjacent free end of two adjacent protruding 21 respectively. The two protrusions 21 play a role in rebound and automatic return of the front impact plate 100 after impact, the two U-shaped protrusions 21 of the elastic sheet 2 are pressed inward, and the pressing force is outward so that the front impact plate 100 is always kept in an initial state. Illustratively, in the present embodiment, the spring 2 includes two protrusions 21 connected by a connecting portion 22, which is advantageous in simplifying the structure of the spring 2.

The clamping groove 11 is of a U-shaped structure, the opening direction of the clamping groove 11 faces the center of the shell 200, and the opening direction of the protrusion 21 is the same as that of the clamping groove 11, so that when the front collision plate 100 collides, the deformation size of the protrusion 21 is large, and the capability of the protrusion 21 for absorbing the collision force of the front collision plate 100 is improved. Alternatively, the side walls of the card slot 11 on both sides in the first direction are disposed perpendicular to the first direction or inclined so that the side walls can restrain the two protrusions 21.

Further, in order to improve the limiting effect on the spring 2, the clamping groove 11 includes two turning portions 111 and two limiting portions 112. The two turning parts 111 are oppositely arranged and are connected with the main body 1, and the distance between the two turning parts 111 is gradually increased along the direction away from the main body 1, so that the U-shaped structure of the bulge 21 of the elastic sheet 2 can be adapted. The two limiting portions 112 are respectively connected with the two turning portions 111 in a one-to-one correspondence manner, and the two limiting portions 112 are used for restraining two sides of the elastic sheet 2 along the first direction so as to achieve a limiting effect. When the collision plate collides, the turning part 111 and the limiting part 112 can be utilized to push the elastic sheet 2 to deform, so that the buffer effect is achieved.

Further, the main body 1 or the shell 200 is provided with the first limiting groove 12 extending along the first direction, the elastic sheet 2 further comprises the first limiting piece 23, the first limiting piece 23 is arranged on the connecting portion 22, when the elastic sheet 2 is located in the clamping groove 11, the connecting portion 22 is located in the first limiting groove 12, the first limiting piece 23 can restrict the connecting portion 22 from moving along the first direction, so that the connecting portion 22 is prevented from moving along the first direction, buffering is performed through deformation of the two protrusions 21, the connecting portion 22 cannot be separated from the constraint of the clamping groove 11, and stability of the elastic sheet 2 is improved. Meanwhile, by using the restraint of the first limiting groove 12, when the front of the front striking plate 100 collides, the connection portion 22 and the two protrusions 21 are deformed under the limiting action of the limiting groove, thereby providing a buffer.

More specifically, the first limiting members 23 are protruding sheet structures on the connecting portion 22, and the two first limiting members 23 are two, and the two first limiting members 23 respectively restrict two sides of the limiting groove, so that the connecting portion 22 is prevented from moving.

When the main body 1 collides, the swing rod 311 is driven to move, so that the trigger piece 312 swings, when the trigger piece 312 swings to the constraint position of the second limiting piece 32, the trigger piece 312 cannot move, at the moment, the displacement of the main body 1 drives the swing rod 311 to rotate, and meanwhile, one end of the swing rod 311 away from the main body 1 swings in the guide groove 3121, so that rigid collision between the trigger piece 312 and the second limiting piece 32 is avoided, and noise generated by collision of the main body 1 is reduced.

Optionally, referring to fig. 7, the trigger switch 31 further includes a reset member 313.

In order to solve this problem, the main body 1 in this embodiment further includes a buffer member 15, the buffer member 15 is sleeved on the limiting post 131, and the outer diameter of the buffer member 15 is spaced from the inner wall of the second limiting groove 141, so as to provide buffering between the limiting post 131 and the second limiting groove 141, further reduce noise, and facilitate improving the service life of the front striker 100.
