[0035] As shown in FIG. 1 and FIG. 2 , in one embodiment, a cleaning robot 10 is provided, comprising a base 100, a wheel assembly 200, a vibration reduction structure 300 and a pump assembly 400. The wheel assembly 200 comprises two driving wheels 210 arranged opposite to each other, and a vibration reduction area 500 is formed between the two driving wheels 210. The vibration reduction structure 300 is arranged between the wheel assembly 200 and the base 100, and is used to reduce vibration of the base 100. The pump assembly 400 comprises an air pump 410 and a water pump 420 mounted on the base 100, and at least one of the center of gravity of the air pump 410 and the center of gravity of the water pump 420 is located in the vibration reduction area 500.

[0036] The cleaning robot 10 in the above embodiment is arranged in the vibration reduction area 500 between the two driving wheels 210 by setting at least one of the center of gravity position of the air pump 410 and the center of gravity position of the water pump 420. The vibration generated by the pump assembly 400 during operation can be transmitted to the vibration reduction structure 300 in time, and the vibration reduction structure 300 between the driving wheel 210 and the base 100 is used to absorb the vibration generated by the pump assembly 400, thereby reducing the vibration and noise caused by the operation of the pump assembly 400 and improving the user experience.

[0037] It should be noted that at least one of the center of gravity of the air pump 410 and the center of gravity of the water pump 420 is located in the vibration reduction area 500, the center of gravity of the air pump 410 may be located in the vibration reduction area 500 and the center of gravity of the water pump 420 may be located outside the vibration reduction area 500, the center of gravity of the air pump 410 may be located outside the vibration reduction area 500 and the center of gravity of the water pump 420 may be located in the vibration reduction area 500, or the center of gravity of the air pump 410 and the center of gravity of the water pump 420 may both be located in the vibration reduction area 500. Specifically in the present embodiment, the center of gravity of the air pump 410 and the center of gravity of the water pump 420 are both located in the vibration reduction area 500.

[0038] Among them, the number of vibration reduction structures 300 can be flexibly adjusted according to the needs of actual use. The vibration reduction structure 300 can be set to any suspended vibration reduction structure in the prior art for robot obstacle crossing. Specifically in this embodiment, the two driving wheels 210 are relatively arranged and can be rotatably installed on the left and right sides of the base 100. The wheel assembly 200 also includes a mounting bracket for installation on the driving wheel 210. The vibration reduction structure 300 is set as a tension spring, and the number of the tension springs is two. The two tension springs are correspondingly arranged on the side of the two driving wheels 210 away from each other, one end of the two tension springs is correspondingly connected to the opposite sides of the mounting bracket, and the other end of the two tension springs is correspondingly connected to the opposite sides of the base 100.

[0039] Optionally, the outer surfaces of the two driving wheels 210 are provided with a vibration-damping layer. In this way, since the vibration-damping layer is provided on the outer surface of the driving wheel 210, the vibration-damping layer also makes the driving wheel 210 itself and the ground have a certain elasticity, and then the elasticity between the vibration-damping layer of the driving wheel 210 and the ground can be used to achieve secondary vibration reduction, further reducing the vibration and noise caused by the operation of the pump assembly 400, and improving the user experience.

[0040] The vibration-damping layer may be configured as a vibration-damping structure such as a rubber tire skin or an elastic cushion tire skin.

[0041] As shown in FIG. 2 , optionally, the plane where the inner side walls of the two driving wheels 210 are opposite to each other is set as a first plane, and in the front-to-back direction of the base 100 (the direction shown by B in FIG. 1 ), the two cross-sections at the front and rear ends of the two driving wheels 210 are set as a second plane, and both the first plane and the second plane are perpendicular to the cross-section at the bottom end of the driving wheel 210, and the space enclosed by the two first planes and the two second planes forms a vibration reduction area 500.

[0042] When the center of gravity of the pump assembly 400 is located in the vibration damping area 500, the entire pump assembly 400 may be located in the vibration damping area 500, or part of the pump assembly 400 may be located in the vibration damping area 500 and the other part may be located outside the vibration damping area 500.

[0043] The position of the pump assembly 400 in the vibration reduction area 500 can be flexibly adjusted according to actual use needs. For example, the pump assembly 400 can be arranged close to one of the driving wheels 210, or in the middle of the two driving wheels 210, as long as the vibration reduction layer on the driving wheel 210 and the vibration reduction structure 300 between the driving wheel 210 and the base 100 can be used to achieve buffering and vibration reduction.

[0044] As shown in Figures 1 and 2, specifically in this embodiment, the cleaning robot 10 further includes a dust box 700 mounted on the base 100.

In this way, the first vibration-damping sleeve 430 also allows a certain elasticity between the air pump 410 and the base 100, and then the elasticity between the first vibration-damping sleeve 430 and the base 100 can be used to achieve vibration reduction, reduce the vibration and noise caused by the operation of the air pump 410, and improve the user experience. Similarly, the second vibration-damping sleeve 440 also allows a certain elasticity between the water pump 420 and the base 100, and then the elasticity between the second vibration-damping sleeve 440 and the base 100 can be used to achieve vibration reduction, reduce the vibration and noise caused by the operation of the water pump 420, and improve the user experience.
