[0052] The present disclosure will be further described in detail below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant content and do not limit the present disclosure. In addition, it should be noted that for the convenience of description, only the parts related to the present disclosure are shown in the drawings.

[0053] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and embodiments.

[0054] Unless otherwise specified, the illustrated exemplary embodiments will be understood to provide exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Accordingly, unless otherwise specified, the features of the various embodiments can be combined, separated, interchanged, and / or rearranged additionally without departing from the technical concept of the present disclosure.

[0055] In the drawings, cross-hatching and / or shading are generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of cross-hatching or shading does not convey or imply any preference or requirement regarding the specific materials, material properties, dimensions, proportions, commonality between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. Additionally, in the drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process orders may be performed in an order different from that described. For example, two consecutively described processes may be performed substantially simultaneously or in an order opposite to that described. Further, the same reference numerals denote the same components.

[0056] When a component is referred to as being "on" or "above" another component, "connected to" or "coupled to" another component, the component can be directly on, directly connected to, or directly coupled to the other component, or there can be an intermediate component. However, when a component is referred to as being "directly on" another component, "directly connected to" or "directly coupled to" another component, there is no intermediate component. To this end, the term "connected" can refer to a physical connection, an electrical connection, etc., and can have or not have an intermediate component.

[0057] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "down", "above", "on", "over", "upper", and "side (e.g., as in "sidewall")" to describe the relationship of one component to another (other) component as shown in the drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacturing. For example, if the device in the drawings is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both "above" and "below" orientations. Further, the device can be positioned otherwise (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted.

[0058] The terms used herein are for the purpose of describing particular embodiments and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are also intended to include the plural forms. In addition, when the terms "comprise" and / or "include" and their variants are used in this specification, it is stated that there are the stated features, integers, steps, operations, components, assemblies and / or groups thereof, but it does not exclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies and / or groups thereof. It should also be noted that, as used herein, the terms "substantially", "about" and other similar terms are used as approximate terms and not as terms of degree, so they are used to explain the inherent deviations of measured values, calculated values and / or provided values that would be recognized by those of ordinary skill in the art.

[0059] Figure 1 is a schematic structural view of a surface cleaning device according to an embodiment of the present disclosure. Figure 2 is a schematic structural view of the surface cleaning device from another angle according to an embodiment of the present disclosure.

[0060] As Figure 1 and Figure 2 shown, the surface cleaning device of the present disclosure can be a self - mobile surface cleaning device; as an example, the self - mobile surface cleaning device can be a floor sweeping robot, a mopping robot, an autonomous mobile surface cleaning robot or a sweeping and mopping integrated robot and other devices. Among them, the self - mobile surface cleaning device can perform autonomous cleaning operations, that is, the surface cleaning device can autonomously move on the surface to be cleaned to clean the surface to be cleaned by sucking the particles located on the surface to be cleaned.

[0061] Taking Figure 1 and Figure 2 the shown sweeping and mopping integrated robot as an example, taking the forward direction of the surface cleaning device as the front, referring to Figure 2 the view direction of, the forward direction of the surface cleaning device is the upper side. The direction away from the forward direction of the surface cleaning device is the rear, referring to Figure 2 the view direction of, the rear of the surface cleaning device refers to the lower side, and this front - rear direction can also be called the longitudinal direction. Correspondingly, the direction perpendicular to the front - rear direction can be defined as the left - right direction, and this left - right direction can also be called the transverse direction.

[0062] The surface cleaning device may include a housing assembly 100, which can be formed as the body of the surface cleaning device; a steering wheel 400 and a driving wheel 500 are provided at the bottom of the housing assembly 100. The steering wheel 400 is used to control the traveling direction of the surface cleaning device, and the driving wheel 500 is used to drive the surface cleaning device forward. The steering wheel 400 is arranged at the front position of the housing assembly 100, and the cleaning assembly 600 is rotatably connected to the bottom of the housing assembly 100, and is located at the rear position of the housing assembly 100.

[0063] As Figure 2 shown, the driving wheels 500 of the present disclosure may be provided as two, and these two driving wheels 500 are respectively located at substantially the middle positions in the front-rear direction of the housing assembly 100 and on both sides in the left-right direction of the housing assembly 100; moreover, the steering wheel 400 is provided as one, which may be a universal wheel. Correspondingly, the universal wheel is arranged at the middle position in the left-right direction of the surface cleaning device and close to the front end of the surface cleaning device. Of course, the steering wheel 400 of the present disclosure may also be provided as two or more.

[0064] During actual use, the driving wheels 500 can be driven to rotate, and by controlling the driving wheels 500 to rotate at a constant speed, the surface cleaning device can move forward. Correspondingly, by controlling the driving wheels 500 to rotate at a non-constant speed, the steering of the surface cleaning device can be controlled.

[0065] In the present disclosure, a side brush assembly 200 is further provided on the housing assembly 100. Among them, the side brush assembly 200 may be provided as one or two; Figure 2 In the shown implementation form, the side brush assembly 200 is provided as one, and the side brush assembly 200 is arranged on the right side of the front end of the housing assembly 100; thus, by the rotation of the side brush assembly 200, the dirt on the surface to be cleaned can be disturbed, and the cleaning of the surface to be cleaned can be achieved. In the present disclosure, the side brush assembly 200 may also be referred to as a side brush assembly.

[0066] In addition, a cleaning assembly 300 is further provided on the housing assembly 100. The cleaning assembly 300 is arranged at the middle position in the front-rear direction of the housing assembly 100, and its length direction is the width direction of the housing assembly 100. More specifically, the cleaning assembly 300 may include a rotary brush, and the rotary brush is rotatably connected to the housing assembly 100, and the rotation axis of the rotary brush is parallel to the surface to be cleaned, for example, parallel to the ground. Figure 2 The specific structure when the cleaning assembly is a rotary brush is shown. The rotation axis of the rotary brush is parallel to the surface to be cleaned. When the rotary brush rotates, the surface to be cleaned can be cleaned, and details are not described herein again.

[0067] Thus, by means of the rotating roller brush of the cleaning assembly 300, the dirt on the surface to be cleaned can be disturbed, and this dirt can be sucked into a device such as a dust box by means of negative pressure adsorption, and the separation of solid particles can be achieved within the device such as the dust box, thereby realizing the cleaning operation of the surface to be cleaned.

[0068] In a preferred embodiment, a cleaning assembly 600 is further provided on the housing assembly 100; in the present disclosure, the cleaning assembly 600 is rotatably connected to the housing assembly 100 and is configured to clean the surface to be cleaned.

[0069] Since the cleaning assembly 300 is located in front of the cleaning assembly 600, the surface cleaning device of the present disclosure can clean the surface to be cleaned by using the cleaning assembly 600 after the cleaning assembly 300 has cleaned the surface to be cleaned.

[0070] Thus, when the surface cleaning device of the present disclosure is working, the cleaning assembly 600 of the surface cleaning device can be self-cleaned according to its working time; more preferably, this working time can vary according to the degree of dirt on the ground. For example, when the degree of dirt on the ground is relatively large, this working time can be set to be relatively short; correspondingly, when the degree of dirt on the ground is relatively small, this working time can be set to be relatively long.

[0071] Meanwhile, when the surface cleaning device has completed the cleaning operation for a predetermined time, it can automatically return and dock at the base station, and the base station can perform self-cleaning on the cleaning assembly 600 of the surface cleaning device.

[0072] Figure 3 is a schematic structural view of the cleaning assembly 600 of a surface cleaning device according to an embodiment of the present disclosure. Figure 4 is a schematic structural view of the cleaning assembly 600 of a surface cleaning device according to an embodiment of the present disclosure from another angle.

[0073] The cleaning assembly 600 of the present disclosure is provided on the housing assembly 100 and is configured to be able to rotate in a first rotation direction about an axis in the vertical direction of the cleaning assembly 600; that is to say, the rotation axis of the cleaning assembly 600 of the present disclosure is in the vertical direction. At this time, the surface to be cleaned is in a substantially horizontal state. In other words, the rotation axis of the cleaning assembly 600 of the present disclosure is perpendicular to or substantially perpendicular to the surface to be cleaned.

[0074] In the cleaning assembly 600 of the present disclosure, it is configured to be able to move between an initial position and an extended position relative to the housing assembly 100; Figure 2 In the shown autonomous mobile surface cleaning robot, its cleaning assembly 600 is located at the initial position. When the cleaning assembly 600 is controlled and moves outward of the housing assembly 100, the cleaning assembly 600 can be in the extended position.

[0075] In a specific embodiment, as Figure 3 and Figure 4 shown, the cleaning assembly 600 of the present disclosure may include components such as an inner disk 610, an outer disk 620, and a reset element 630.

[0076] The inner disk 610 and the outer disk 620 are concentrically arranged. That is to say, the central axis of the inner disk 610, the central axis of the outer disk 620, and the rotation axis of the entire cleaning assembly 600 can be coincidentally arranged.

[0077] In a preferred embodiment, the outer diameter of the outer disk 620 is greater than the outer diameter of the inner disk 610; correspondingly, in the radial direction of the cleaning assembly 600, the outer disk 620 is located outside the inner disk 610. At this time, when the cleaning assembly 600 moves with the self - moving surface cleaning robot, the outer disk 620 can contact an obstacle. Correspondingly, the inner disk 610 does not contact the obstacle, so that the outer disk 620 can play a certain protective role for components such as the inner disk 610 and the drive shaft.

[0078] In other words, when an external force acts on the outer disk 620, the outer disk 620 can move relative to the inner disk 610 in the horizontal direction (i.e., along a certain radial direction of the inner disk 610), and cause the inner disk 610 and the outer disk 620 to deviate from the concentric position. At this time, the reset element 630 can be used to make one of the inner disk 610 and the outer disk 620 return to the concentric position after deviating from the concentric position.

[0079] The structures of the outer disk and the inner disk will be described below with reference to the drawings.

[0080] Figure 5 is a schematic structural diagram of the outer disk of a surface cleaning device according to an embodiment of the present disclosure. Figure 6 is a schematic structural diagram of the cooperation between the outer disk and the reset element according to an embodiment of the present disclosure.

[0081] As Figure 5 and Figure 6 shown, the outer disk 620 includes a disk - shaped base body, and the outer disk 620 has a second protrusion 621 on the side facing the inner disk 610. Specifically, the outer disk 620 can be located above the inner disk 610. Correspondingly, the second protrusion 621 is located below the base body of the outer disk 620.

[0082] In a preferred embodiment, the base of the outer disk 620 has a through hole (central hole), at least part of the inner disk 610 is located within the through hole, and the inner disk 610 is connected to the drive shaft; alternatively, the drive shaft passes through the through hole and is connected to the inner disk 610, whereby the inner disk 610 can receive and transmit the driving force of the drive shaft, and the driving force of the drive shaft causes the inner disk 610 and the outer disk 620 to rotate together.

[0083] In the present disclosure, the drive shaft can not only be driven to rotate, but can also be driven to generate a lifting motion, so that different contact forces can be provided between the cleaning assembly 600 of the present disclosure and the surface to be cleaned.

[0084] Figure 7 It is a schematic diagram of the cooperation structure between the inner disk and the reset element according to an embodiment of the present disclosure.

[0085] As Figure 7 shown, in the present disclosure, the inner disk 610 has a first protrusion 611 on the side facing the outer disk 620; moreover, the inner disk 610 may also include a base body in a substantially disc shape. At this time, the first protrusion 611 may be located above the base body of the inner disk 610. At this time, a substantially annular space will be formed between the upper surface of the base body of the inner disk 610, the first protrusion 611, the lower surface of the base body of the outer disk 620, and the second protrusion 621. The reset element 630 is disposed between the first protrusion 611 and the second protrusion 621, that is, within the substantially annular space.

[0086] As Figure 6 and Figure 7 shown, in the present disclosure, the first protrusion 611 is formed with a first abutting portion, which is a partial outer peripheral surface of the first protrusion 611; moreover, the number of the first abutting portions is related to the shape of the reset element 630. Taking Figure 7 the shape of the reset element 630 shown, the number of the first abutting portions is formed as three.

[0087] The second protrusion 621 is formed with a second abutting portion, which is a partial inner peripheral surface of the second protrusion 621; moreover, the number of the second abutting portions is related to the shape of the reset element 630. Taking Figure 6 the shape of the reset element 630 shown, the number of the second abutting portions is formed as three.

[0088] The acting portions of the reset element 630 respectively abut against the first abutting portion and the second abutting portion. In other words, the number of the acting portions of the reset element 630 is the sum of the numbers of the first abutting portion and the second abutting portion. In the Figure 6 and Figure 7 shown embodiment, the number of the acting portions of the reset element 630 is six, and these six acting portions respectively correspond to the three corner portions and the middle portions of the three sides of the reset element 630.

[0089] In a preferred embodiment, at least one of the first protrusion 611 and the second protrusion 621 has a cylindrical surface (i.e., a cylindrical circumferential surface). More preferably, both the first protrusion 611 and the second protrusion 621 have cylindrical surfaces, and the cylindrical surface of the first protrusion 611 is located outside the second protrusion 621; or the cylindrical surface of the second protrusion 621 is located outside the first protrusion 611. That is to say, the present disclosure does not limit the position between the first protrusion 611 and the second protrusion 621.

[0090] In a preferred solution, as Figure 8 shown, the second protrusion 621 is formed as an annular protrusion, and the first protrusion 611 is formed as a cylindrical protrusion. At this time, the second protrusion 621 is disposed around the first protrusion 611.

[0091] In the present disclosure, the reset element 630 includes an elastic member. Preferably, the elastic member can be a spring, and the spring can be arranged in a plurality along the circumferential direction of the first protrusion 611. One end of these springs abuts on the first protrusion 611, and the other end abuts on the second protrusion 621, so as to reset the outer disc 620 through the elastic force provided by these springs.

[0092] In another embodiment, the reset element 630 includes an elastic ring. The elastic ring has a first acting portion and a second acting portion. The first acting portion is used to abut against the first protrusion 611, and the second acting portion is used to abut against the second protrusion 621. The first acting portion and the second acting portion are alternately arranged. Among them, the first acting portion can be the middle part of the edge of the elastic ring, and the second acting portion can be the corner of the elastic ring.

[0093] As Figure 6 and Figure 7 shown, the elastic ring is triangular as a whole. Of course, the elastic ring can also be quadrilateral or pentagonal (pentagon), etc.

[0094] In the present disclosure, both the outer disc 620 and the inner disc 610 are rigid discs, that is, both the inner disc 610 and the outer disc 620 can be prepared from relatively hard plastics or metals and the like, so as to improve the impact resistance of the outer disc 620 and the inner disc 610.

[0095] More preferably, an annular impact plate (not shown in the figure) is arranged along the outer edge of the outer disc 620. Thus, the outer disc 620 is protected by the annular impact plate from being damaged by external obstacles.

[0096] As Figure 3 shown, the autonomous mobile surface cleaning robot of the present disclosure further includes a locking structure for detachably connecting the inner disc 610 and the outer disc 620.

[0097] In a specific embodiment, the latch structure includes a lock head 612 and a chute 622. After the lock head 612 is inserted into the chute 622, it can restrict the relative movement of the inner disk 610 and the outer disk 620 in the vertical direction, and allow the outer disk 620 to move relative to the inner disk 610 in the radial and circumferential directions of the inner disk 610 or the outer disk 620.

[0098] Specifically, the lock head 612 can be formed on the base body of the inner disk 610. Correspondingly, the chute 622 is formed on the base body of the outer disk 620. Of course, the lock head 612 can also be formed on the base body of the outer disk 620, and the chute 622 can also be formed on the base body of the inner disk 610. The present disclosure does not limit this.

[0099] As Figure 4 shown, the chute 622 has a length direction and a width direction. The length direction of the chute 622 is arranged along the radial direction of the outer disk 620. Correspondingly, the width direction of the chute 622 is arranged along the circumferential direction of the outer disk 620. When the lock head 612 is in locking cooperation with the chute 622, at least a part of the lock head 612 is located in the chute 622, and the dimension of the part of the lock head 612 located in the chute 622 along the length direction of the chute 622 is smaller than the length of the chute 622, and the dimension along the width direction of the chute 622 is smaller than the width of the chute 622. Thus, the lock head 612 can generate a small amount of movement in the chute 622. Correspondingly, the outer disk 620 can displace relative to the inner disk 610 in the horizontal direction.

[0100] In a preferred embodiment, the lock head 612 and the chute 622 are arranged uniformly along the circumferential direction near the outer edges of the inner disk 610 and the outer disk 620. In a preferred embodiment, both the lock head 612 and the chute 622 can be set to three. Through the setting of these three lock heads 612 and chutes 622, not only can the inner disk 610 and the outer disk 620 be stably held in the vertical direction, but also the outer disk 620 can easily move relative to the inner disk 610 in the horizontal direction.

[0101] In the present disclosure, a cleaning member made of flannel can be provided on the inner disk 610 or the outer disk 620, so as to realize the cleaning of the surface to be cleaned through the frictional contact between the cleaning member and the surface to be cleaned.

[0102] As Figure 2As shown, two cleaning components 600 of the present disclosure are provided. These two cleaning components 600 are respectively arranged on the left and right sides of the rear end of the housing component 100. In one embodiment, when these two cleaning components 600 rotate, they can contact the surface to be cleaned under pressure, so as to realize wet mopping of the surface to be cleaned, thereby realizing wet cleaning of the surface to be cleaned. Correspondingly, during the cleaning process of the surface to be cleaned, in the left-right direction, since there is no gap or the gap is small between the cleaning parts, there will be no area where cleaning is missed.
