[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, a cleaning robot 10 is provided, including a base 100, a wheel assembly 200, a vibration damping structure 300, and a pump assembly 400. The wheel assembly 200 includes two opposing drive wheels 210, forming a vibration damping region 500 between the two drive wheels 210. The vibration damping structure 300 is disposed between the wheel assembly 200 and the base 100 and is used to dampen the vibration of the base 100. The pump assembly 400 includes an air pump 410 and a water pump 420 mounted on the base 100, with at least one of the centers of gravity of the air pump 410 and the water pump 420 located within the vibration damping region 500.

[0036] In the above embodiment, the cleaning robot 10 is positioned within the vibration damping area 500 between the two drive wheels 210 by at least one of the center of gravity positions of the air pump 410 and the water pump 420. The vibration generated by the pump assembly 400 during operation can be transmitted to the vibration damping structure 300 in a timely manner. The vibration damping structure 300 between the drive wheel 210 and the base 100 absorbs the vibration generated by the pump assembly 400, 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 centers of gravity of the air pump 410 and the water pump 420 is located within the vibration damping region 500. This can be because the center of gravity of the air pump 410 is located within the vibration damping region 500 while the center of gravity of the water pump 420 is located outside the vibration damping region 500; or the center of gravity of the air pump 410 is located outside the vibration damping region 500 while the center of gravity of the water pump 420 is located within the vibration damping region 500; or both the center of gravity of the air pump 410 and the center of gravity of the water pump 420 are located within the vibration damping region 500. Specifically, in this embodiment, both the center of gravity of the air pump 410 and the center of gravity of the water pump 420 are located within the vibration damping region 500.

[0038] The number of vibration damping structures 300 can be flexibly adjusted according to actual usage needs. The vibration damping structure 300 can be any existing suspension vibration damping structure used for robot obstacle crossing. Specifically, in this embodiment, two drive wheels 210 are arranged opposite each other and can be rotatably mounted on the left and right sides of the base 100. The wheel assembly 200 also includes mounting brackets for mounting the drive wheels 210. The vibration damping structure 300 is configured as a tension spring, with two tension springs. The two tension springs are correspondingly arranged on the opposite sides of the two drive wheels 210, with one end of each tension spring connected to the opposite sides of the mounting bracket, and the other end of each tension spring connected to the opposite sides of the base 100.

[0039] Optionally, both drive wheels 210 have a vibration damping layer on their outer surfaces. Thus, because the drive wheels 210 have a vibration damping layer on their outer surfaces, the layer provides a certain degree of elasticity between the drive wheels 210 and the ground. Furthermore, the elasticity between the drive wheels 210's vibration damping layer and the ground can be used to achieve secondary vibration damping, 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 can be set as a vibration damping structure such as a rubber tire layer or an elastic pad tire layer.

[0041] like Figure 2 As shown, optionally, the plane containing the inner sidewalls of the two drive wheels 210 facing each other is set as the first plane, along the front-rear direction of the base 100 (e.g., Figure 1 In the direction shown in B, the two tangents at the front and rear ends of the two drive wheels 210 are set as the second plane. The first plane and the second plane are both perpendicular to the tangent at the bottom end of the drive wheel 210. The space enclosed by the two first planes and the two second planes forms a vibration damping area 500.

[0042] When the center of gravity of the pump assembly 400 is located within the vibration damping area 500, the entire pump assembly 400 may be located within the vibration damping area 500, or a portion of the pump assembly 400 may be located within the vibration damping area 500 and another portion may be located outside the vibration damping area 500.

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

[0044] like Figure 1 and Figure 2 As shown, specifically in this embodiment, the cleaning robot 10 also includes a dust box 700 mounted on the base 100. Along a direction perpendicular to the forward movement of the cleaning robot 10 (e.g., ... Figure 2 (In the direction shown by C), the pump assembly 400 is provided with a drive wheel 210 and a dust box 700 on the adjacent two sides respectively.

[0045] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, the pump assembly 400 further includes a first damping sleeve 430 covering the outer surface of the air pump 410 and a second damping sleeve 440 covering the outer surface of the water pump 420. Both the first damping sleeve 430 and the second damping sleeve 440 are mounted on the base 100. Thus, the first damping sleeve 430 provides a certain degree of elasticity between the air pump 410 and the base 100, thereby achieving vibration reduction and lowering the vibration and noise caused by the operation of the air pump 410, improving the user experience. Similarly, the second damping sleeve 440 provides a certain degree of elasticity between the water pump 420 and the base 100, thereby achieving vibration reduction and lowering the vibration and noise caused by the operation of the water pump 420, improving the user experience.

[0046] like Figure 3 and Figure 4 As shown, the cleaning robot 10 further includes a pipe plate assembly 610 for detecting water shortage and fullness in the clean water tank. The pipe plate assembly 610 is installed below the water pump 420 and is connected to the water pump 420.

[0047] It should be noted that the first damping sleeve 430 can be installed on the base 100 by snap-fit, screw-fit, plug-in, or other fixed connection methods. The second damping sleeve 440 can be installed on the base 100 and the pipe plate assembly 610 by snap-fit, screw-fit, plug-in, or other fixed connection methods. The pipe plate assembly 610 can be installed on the base 100 and the first damping sleeve 430 by snap-fit, screw-fit, plug-in, or other fixed connection methods.

[0048] like Figure 2 and Figure 3As shown, specifically in this embodiment, the cleaning robot 10 also includes a wastewater tank and a water circuit board mounted on the base 100. An air pump 410 is connected to the wastewater tank and is used to evacuate the wastewater tank, creating a negative pressure inside to draw in wastewater. The clean water tank, water pump 420, and water circuit board are interconnected via a pipe board assembly 610. The water pump 420 can draw water from the clean water tank, and the water pumped by the water pump 420 flows through the pipe board assembly 610 and out through the water circuit board.

[0049] like Figure 3 , Figure 4 and Figure 5 As shown, optionally, the top of the pipe plate assembly 610 is provided with a first fixing part 611, and the bottom of the second vibration damping sleeve 440 is provided with a second fixing part 441, the second fixing part 441 being fixedly connected to the first fixing part 611. Thus, the second fixing part 441 provides a certain degree of elasticity between the water pump 420 and the first fixing part 611, thereby utilizing the elasticity between the second fixing part 441 and the first fixing part 611 to achieve vibration damping, reducing the vibration and noise caused by the operation of the water pump 420, and improving the user experience.

[0050] like Figure 3 , Figure 4 and Figure 5 As shown, optionally, the air pump 410 is located on one side of the pipe plate assembly 610. The first vibration damping sleeve 430 has a third fixing part 431 on the side near the pipe plate assembly 610, and the third fixing part 431 is fixed to the base 100. The pipe plate assembly 610 has a fourth fixing part 612 on the side near the first vibration damping sleeve 430, and the fourth fixing part 612 is fixed to the third fixing part 431. In this way, the third fixing part 431 also provides a certain elasticity between the fourth fixing part 612 and the base 100, thereby utilizing the elasticity between the third fixing part 431 and the base 100 to achieve vibration damping, reduce the vibration and noise caused by the operation of the water pump 420, and improve the user experience.

[0051] like Figure 4 , Figure 5 and Figure 6As shown, specifically in this embodiment, the third fixing part 431 is provided with a first mounting hole 432, and the fourth fixing part 612 is provided with a second mounting hole 613 corresponding to the first mounting hole 432. The base 100 is provided with a first stud 111, which passes through the first mounting hole 432 and extends into the second mounting hole 613. The cleaning robot 10 also includes a first screw connector, which is threadedly connected to the first stud 111 to fix the third fixing part 431, the fourth fixing part 612, and the base 100 into one unit. Thus, during assembly, the third fixing part 431 can be sleeved on the first stud 111, then the fourth fixing part 612 can be sleeved on the first stud 111, and finally the first screw connector can be inserted into the first stud 111 from the second mounting hole 613 and screwed to the first stud 111, improving the ease of assembly of the cleaning robot 10.

[0052] like Figure 3 , Figure 4 and Figure 6 As shown, optionally, the first damping sleeve 430 is further provided with a fifth fixing part 433 on the side away from the pipe plate assembly 610, and the fifth fixing part 433 is fixed to the base 100. Specifically, in this embodiment, the fifth fixing part 433 is provided with a third mounting hole 434, and the base 100 is provided with a second stud 112, which extends into the third mounting hole 434. The cleaning robot 10 also includes a second screw connector, which is threadedly connected to the second stud 112 to fix the fifth fixing part 433 and the base 100 as a whole.

[0053] like Figure 3 , Figure 5 and Figure 6 As shown, optionally, the pipe plate assembly 610 is further provided with a sixth fixing part 614 on the side away from the first vibration damping sleeve 430, and the sixth fixing part 614 is fixed to the base 100. Specifically, in this embodiment, the sixth fixing part 614 is provided with a fourth mounting hole 615, and the base 100 is provided with a third stud 113, which extends into the fourth mounting hole 615. The cleaning robot 10 also includes a third screw connector, which is threadedly connected to the third stud 113 to fix the sixth fixing part 614 and the base 100 as a whole.

[0054] like Figure 3 , Figure 4 and Figure 6As shown, optionally, the second damping sleeve 440 is further provided with a seventh fixing part 442 on the side away from the first damping sleeve 430, and the seventh fixing part 442 is fixed to the base 100. Specifically, in this embodiment, the seventh fixing part 442 is provided with a fifth mounting hole 443, and the base 100 is provided with a fourth stud 114, which extends into the fifth mounting hole 443. The cleaning robot 10 also includes a fourth screw connector, which is threadedly connected to the fourth stud 114 to fix the seventh fixing part 442 and the base 100 as a whole.

[0055] The first, second, and third threaded connectors can all be configured as screws, bolts, or other threaded connection structures.

[0056] In this specific embodiment, the base 100 can be integrally formed with the first stud 111, the second stud 112, the third stud 113, and the fourth stud 114. The first damping sleeve 430 can be integrally formed with the third fixing part 431 and the fifth fixing part 433 using damping material. The second damping sleeve 440 can be integrally formed with the second fixing part 441 and the seventh fixing part 442 using damping material. The pipe plate assembly 610 can be integrally formed with the first fixing part 611, the fourth fixing part 612, and the sixth fixing part 614.

[0057] like Figure 3 and Figure 6 As shown, in one embodiment, the base 100 is partially recessed to form a mounting groove 120, which is at least partially located within the vibration damping region 500, and the pump assembly 400 is mounted in the mounting groove 120. This reduces the height of the pump assembly 400 relative to the base 100, increasing the stability of the base 100 to reduce its vibration amplitude, thereby reducing the vibration and noise caused by the operation of the pump assembly 400 and improving the user experience.

[0058] Specifically, in this embodiment, the pipe plate assembly 610 and the air pump 410 encased in the first vibration damping sleeve 430 are both installed in the mounting groove 120. The water pump 420 encased in the second vibration damping sleeve 440 is installed above the pipe plate assembly 610. Along the forward direction of the cleaning robot 10, the water pump 420 is located in front of the air pump 410. The pump assembly 400 is connected to the pipe plate assembly 610 as a whole to form a pumping structure, and the inner contour shape of the mounting groove 120 is adapted to the outer contour shape of the pumping structure. The first stud 111, the second stud 112, the third stud 113, and the fourth stud 114 are all correspondingly disposed in the mounting groove 120.

[0059] like Figure 3As shown, specifically in this embodiment, the bottom wall of the mounting groove 120 is provided with a first support rib and a second support rib. There is at least one first support rib, spaced apart, which cooperate to support the air pump 410 encased in the first vibration damping sleeve 430. There is at least one second support rib, spaced apart, which cooperate to support the pipeline plate assembly 610. Thus, the first support rib reduces the contact area between the first vibration damping sleeve 430 and the base 100, allowing the first vibration damping sleeve 430 to absorb more vibrations generated by the air pump 410, reducing the vibration and noise impact caused by the operation of the air pump 410, and improving the user experience. Furthermore, the second support rib reduces the hard contact area between the pipeline plate assembly 610 and the base 100, allowing more vibrations from the pipeline plate assembly 610 to be transmitted to the first vibration damping sleeve 430 and the second vibration damping sleeve 440, enabling the first vibration damping sleeve 430 and the second vibration damping sleeve 440 to absorb more vibrations, reducing the vibration and noise impact caused by the operation of the pump assembly 400, and improving the user experience.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0063] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0064] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0065] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
