Description

Technical Field

[0001] The present disclosure relates to an autonomous mobile surface cleaning robot. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] With the advancement of technology, more and more families use surface cleaning equipment such as sweeping robots to clean the surface to be cleaned.

[0004] In order to make the surface cleaning devices have a higher cleaning effect, these surface cleaning devices all include cleaning components, which can wet-mop the surface to be cleaned, so that the surface to be cleaned is cleaner after being cleaned by the surface cleaning devices.

[0005] Moreover, in order to improve the cleaning effect of the surface cleaning equipment and prevent the cleaning components of the surface cleaning equipment from colliding with obstacles, the cleaning components of the surface cleaning equipment in the prior art have two degrees of freedom of movement: rotation and lifting. Accordingly, these two degrees of freedom of movement need to be driven independently, so that the cleaning components of the surface cleaning equipment need to include two driving devices, which undoubtedly increases the cost of the surface cleaning equipment.

[0053] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the relevant content and are not intended to limit the present disclosure. It should also be noted that, for ease of description, only the portions relevant to the present disclosure are shown in the accompanying drawings.

[0054] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0055] Unless otherwise stated, the exemplary embodiments / examples shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of the various embodiments / examples may be further combined, separated, interchanged, and / or rearranged without departing from the technical concepts of the present disclosure.

[0056] The use of cross hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise indicated, the presence or absence of cross hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the order described. In addition, the same figure numbers represent the same components.

[0057] When a component is referred to as being “on,” “over,” “connected to,” or “coupled to” another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another component, there are no intervening components present. For this purpose, the term “connected” may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0058] For descriptive purposes, the present disclosure may use spatially relative terms such as "below," "beneath," "under," "down," "above," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the drawings is turned over, a component described as "below" or "beneath" another component or feature would then be positioned "above" the other component or feature. Thus, the exemplary term "below" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and as such, the spatially relative descriptors used herein should be interpreted accordingly.

[0059] The terms used herein are for the purpose of describing specific embodiments and are not intended to be restrictive. As used herein, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, the features, integral bodies, steps, operations, parts, assemblies and / or their groups stated are explained, but the presence or addition of one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups is not excluded. It should also be noted that, as used herein, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values and / or the values provided that will be recognized by those of ordinary skill in the art.

[0060] like Figure 1 and Figure 2As shown, the surface cleaning device of the present disclosure may be a self-propelled surface cleaning device; as an example, the self-propelled surface cleaning device may be a sweeping robot, a mopping robot, an autonomous surface cleaning robot, or a sweeping and mopping robot. The self-propelled surface cleaning device is capable of performing an autonomous cleaning operation, i.e., the surface cleaning device is capable of autonomously moving over the surface to be cleaned to clean the surface by sucking up particles on the surface to be cleaned.

[0061] by Figure 1 and Figure 2 The autonomous mobile surface cleaning robot shown in the figure is taken as an example, and the forward direction of the surface cleaning device is marked as the front. Figure 2 The viewing direction of the surface cleaning equipment is the upper side. The direction away from the surface cleaning equipment is the rear. Figure 2 In the viewing direction of the surface cleaning device, the rear side refers to the lower side, and the front-to-back direction can also be referred to as the longitudinal direction. Accordingly, the direction perpendicular to the front-to-back direction can be defined as the left-right direction, which can also be referred to as the transverse direction.

[0062] The surface cleaning device may include a housing assembly 100, which may form the body of the surface cleaning device. A steering wheel 400 and a running wheel 500 are provided at the bottom of the housing assembly 100. The steering wheel 400 is used to control the direction of travel of the surface cleaning device, and the running wheel 500 is used to drive the surface cleaning device forward. The steering wheel 400 is provided at the front 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 of the housing assembly 100.

[0063] like Figure 2 As shown, the present disclosure can be provided with two running wheels 500, which are respectively located approximately in the middle of the front-to-back direction of the housing assembly 100 and on both sides of the left-to-right direction of the housing assembly 100; furthermore, the steering wheel 400 is provided as one, which can be a universal wheel, and accordingly, the universal wheel is provided in the middle of the left-to-right direction of the surface cleaning device and close to the front end of the surface cleaning device. Of course, the present disclosure can also be provided with two or more steering wheels 400.

[0064] In actual use, the travel wheel 500 can be driven and rotated, and by controlling the travel wheel 500 to rotate at a constant speed, the surface cleaning device can move forward. Correspondingly, by controlling the travel wheel 500 to rotate at an uneven speed, the surface cleaning device can be controlled to turn.

[0065] In the present disclosure, a side brush assembly 200 is further provided on the housing assembly 100, wherein the side brush assembly 200 can be provided as one or two; Figure 2 In the illustrated embodiment, the side brush assembly 200 is provided as a single unit and is disposed on the right side of the front end of the housing assembly 100. Thus, the rotation of the side brush assembly 200 can disturb dirt on the surface to be cleaned and clean the surface to be cleaned. In this disclosure, the side brush assembly 200 may also be referred to as a side brush assembly.

[0066] In addition, the housing assembly 100 is further provided with a cleaning assembly 300, which is disposed in the middle of the housing assembly 100 in the front-to-back direction, with its length being the width of the housing assembly 100. More specifically, the cleaning assembly 300 may include a roller brush that is rotatably connected to the housing assembly 100, with its rotation axis parallel to the surface to be cleaned, for example, the ground. Figure 2 The specific structure when the cleaning component is a roller brush is shown. The rotation axis of the roller brush is parallel to the surface to be cleaned. When the roller brush rotates, it can clean the surface to be cleaned. No further details are given here.

[0067] Therefore, the rotating roller brush of the cleaning component 300 can disturb the dirt on the surface to be cleaned. The dirt can be sucked into the dust box and other devices through negative pressure adsorption, and the solid particles can be separated in the dust box and other devices, thereby completing the cleaning operation of the surface to be cleaned.

[0068] In a preferred embodiment, the housing assembly 100 is further provided with a cleaning assembly 600. 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. Specifically, the cleaning assembly 600 is configured to selectively contact the surface to be cleaned, thereby cleaning the surface to be cleaned by the cleaning assembly 600.

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

[0070] Thus, when the surface cleaning device of the present disclosure is in operation, the cleaning assembly 600 of the surface cleaning device can be self-cleaned according to its operating time; more preferably, the operating time can be set to be different according to the degree of dirtiness of the ground. For example, when the degree of dirtiness of the ground is relatively high, the operating time can be set to be relatively short; correspondingly, when the degree of dirtiness of the ground is relatively low, the operating time can be set to be relatively long.

[0071] At the same time, after the surface cleaning device completes the cleaning operation for a predetermined time, it can automatically return to and dock at the base station, and the base station can perform self-cleaning on the cleaning component 600 of the surface cleaning device.

[0072] Figure 3 1 is a partial structural diagram of a surface cleaning device according to one embodiment of the present disclosure. Figure 4 1 is a schematic structural diagram of a cleaning assembly 600 of a surface cleaning device according to one embodiment of the present disclosure. Figure 5 yes Figure 4 A magnified schematic diagram of part A. Figure 6 It is a schematic structural diagram of a cleaning component according to one embodiment of the present disclosure. Figure 7 It is a schematic structural diagram of a cleaning component according to an embodiment of the present disclosure from another angle. Figure 8 2 is a schematic structural diagram of a first driving member and a second driving member according to an embodiment of the present disclosure.

[0073] like Figures 3 to 8 As shown, the cleaning assembly 600 of the present disclosure may include: a driving device 610, a first driving member 620, a second driving member 630, a cleaning component 640 and a damping member 650. Therefore, when the cleaning assembly 600 of the present disclosure is in use, when the driving device 610 rotates, it can not only drive the cleaning component 640 to rotate, but also drive the cleaning component 640 to generate a lifting motion.

[0074] In the present disclosure, the driving device 610 is arranged in the shell assembly 100; specifically, when the cleaning assembly 600 cannot be displaced in the horizontal direction relative to the shell assembly 100, the driving device 610 can be directly fixed to the shell assembly 100; in addition, when the cleaning assembly 600 can be displaced in the horizontal direction relative to the shell assembly 100, that is, when the cleaning assembly 600 has an inward-retracted state and an outward-expanded state, the cover part of the cleaning assembly 600 can be rotatably arranged in the shell assembly 100, and at this time the driving device 610 is fixedly connected to the cover part of the cleaning assembly 600.

[0075] The driving device 610 may be a motor, and the motor may be connected to a reducer. In other words, the motor may directly drive the first driving member 620 to rotate, or indirectly drive the first driving member 620 to rotate via the reducer.

[0076] The first driving member 620 is configured to receive the driving force output by the driving device 610. In other words, the first driving member 620 of the present disclosure can be driven and rotated by the driving device 610. As a result, the first driving member 620 is vertically restricted. In other words, in the present disclosure, the first driving member 620 can only generate rotational motion and cannot generate vertical movement.

[0077] The second driving member 630 is located outside the first driving member 620 and is configured to cooperate with the first driving member 620 so that when the first driving member 620 rotates, the second driving member 630 can move back and forth relative to the first driving member 620 and / or can rotate.

[0078] That is to say, the first driving member 620 of the present disclosure can be called an inner sleeve, and the second driving member 630 can be called an outer sleeve. At this time, at least part of the first driving member 620 is located inside the second driving member 630, so that the first driving member 620 can cooperate with the second driving member 630.

[0079] Specifically, the inner side of the second driving member 630 has a guide groove 631 extending along at least a portion of the axial direction of the second driving member 630. In a preferred embodiment, the guide groove 631 comprises a spiral groove. In other words, the inner surface of the second driving member 630 of the present disclosure can be formed into a substantially internally threaded structure.

[0080] The outer side of the first driving member 620 has a protrusion 621 extending outward at least along the radial direction of the first driving member 620. In a preferred embodiment, the protrusion 621 is located in the middle or lower end of the first driving member 620. In a preferred embodiment, the protrusion 621 includes a bump or a ridge.

[0081] In the present disclosure, the protrusion 621 is also configured to extend in the axial direction along the outer side of the first driving member 620, that is, the protrusion 621 of the present disclosure has a certain thickness, and the protrusion 621 is configured to be inclined so that the protrusion 621 can slide in the spiral groove without being stuck in the spiral groove.

[0082] Accordingly, the rotation direction of the spiral groove can be set to different directions according to actual needs. In one embodiment, the rotation direction of the spiral groove can be as follows: Figure 8 Furthermore, a limiting element 660 is provided at the upper end of the second driving member 630 .

[0083] In the present disclosure, the limiting element 660 is provided on the second driving member 630 to limit the relative movement between the first driving member 620 and the second driving member 630. In other words, the limiting element 660 of the present disclosure and the second driving member 630 can be fixed together, and at least a portion of the limiting element 660 is used to limit the protrusion of the first driving member 620.

[0084] Specifically, the lower end of the guide groove 631 of the second driving member 630 does not penetrate the second driving member 630. That is, the lower end of the guide groove 631 of the second driving member 630 has a stopper, and this stopper prevents the protrusion 621 of the first driving member 620 from escaping from the lower end of the guide groove 631. Furthermore, the limiting element 660 is fixed to the upper end of the second driving member 630 and blocks the upper end of the guide groove 631 of the second driving member 630 through the limiting element 660, so that the protrusion 621 of the first driving member 620 cannot escaping from the upper end of the guide groove 631.

[0085] When the first driving member 620, the second driving member 630 and the limiting element 660 are assembled together, the protrusion of the first driving member 620 can be placed in the guide groove 631 first, and then the limiting element 660 can be installed on the upper end of the second driving member 630 to realize the installation of the actuating assembly, and the installation process is convenient.

[0086] Therefore, when the cleaning component 600 of the present invention is working, the second driving member 630 is in the first position (the maximum position in the upward direction); at the first position, if the first driving member 620 is driven and rotated clockwise (viewed from the top-down direction of the surface cleaning device, the same below), the protrusion 621 of the first driving member 620 will be limited by the limiting portion at the lower end of the guide groove 631 of the second driving member 630, and the second driving member 630 will rotate clockwise synchronously with the first driving member 620. At this time, although the cleaning component 600 is not in contact with the surface to be cleaned, cleaning liquid can be provided to the cleaning component 600 when the cleaning component 600 rotates, and the cleaning component 600 can be moistened and in a state capable of cleaning the surface to be cleaned.

[0087] At this first position, if the first driving member 620 is driven and rotated counterclockwise (as viewed from the top, the same applies below), the protrusion 621 of the first driving member 620 will slide within the guide slot 631 of the second driving member 630. Since the vertical position of the first driving member 620 remains unchanged, the second driving member 630 will be pushed downward. Next, as the second driving member 630 gradually descends and reaches the second position (which can be the maximum downward position), the protrusion 621 will be restrained by the restraining element 660. At this point, the second driving member 630 will not descend further, but will rotate counterclockwise in sync with the first driving member 620.

[0088] Since at least a portion of the cleaning assembly 600 will be in contact with the surface to be cleaned when the second driving member 630 is in the second position, the cleaning assembly 600 can be driven and rotated by the second driving member 630 when the second driving member 630 rotates, thereby achieving wet cleaning of the surface to be cleaned. In particular, the cleaning assembly 600 can clean locations such as corners, thereby improving the cleaning effect of the surface cleaning equipment.

[0089] In the present disclosure, the damping member 650 is disposed between the second driving member 630 and the housing assembly 100 to provide damping to the second driving member 630 .

[0090] In a specific embodiment, when the cleaning component 600 cannot be displaced in the horizontal direction relative to the shell component 100, the damping member 650 can be directly fixed to the shell component 100; in addition, when the cleaning component 600 can be displaced in the horizontal direction relative to the shell component 100, that is, when the cleaning component 600 has an inward-retracted state and an outward-expanded state, the cleaning component 600 can include a plate component 670 that can slide relative to the shell component 100, and the damping member 650 can be fixed on the plate component 670.

[0091] In the present disclosure, the damping member 650 may be formed in a ring shape and sleeved on the outside of the second driving member 630 , thereby enabling the damping member 650 to apply preset damping to the second driving member 630 .

[0092] Specifically, the damping force applied by the damping member 650 to the second driving member 630 must ensure that the second driving member 630 does not rotate during the ascent or descent process, or even if the second driving member 630 rotates during the ascent or descent process, the rotation speed of the second driving member 630 is slower than that of the first driving member 620. In other words, the second driving member 630 cannot rotate at the same speed as the first driving member 620 during the ascent or descent process, otherwise the second driving member 630 will not be able to ascend or descend.

[0093] In a specific embodiment, a hole structure may be formed on the plate component 670 of the present disclosure, and the damping member 650 may be disposed in the hole structure, so that the damping member 650 cannot move relative to the plate component 670 .

[0094] In the present disclosure, the cleaning member 640 is disposed on the second driving member 630 and is driven by the second driving member 630 to rotate and rise and fall.

[0095] Specifically, the cleaning component 640 is detachably connected to the second driving member 630. Thus, after the autonomous mobile surface cleaning robot has been operating for a predetermined period of time, the user can remove the cleaning component 640 from the second driving member 630 and continue cleaning. In addition, if the cleaning component 640 is damaged, it can be easily replaced.

[0096] Figure 9 Schematic diagram of the structure of an elastic element according to one embodiment of the present disclosure.

[0097] In a preferred embodiment, Figure 9 As shown, an elastic element 680 is arranged between the cleaning member 640 and the second driving member 630 to provide a buffering force between the cleaning member 640 and the second driving member 630 .

[0098] The first portion of the second driving member 630 is located outside the first driving member 620, and the second portion of the second driving member 630 can be located inside the first driving member 620. In other words, a protrusion is formed at the lower end of the second driving member 630, and when the second driving member 630 moves to the maximum upward position, the protrusion can move into the interior of the first driving member 620. At this time, the elastic element 680 is located between the cleaning component 640 and the second portion of the second driving member 630.

[0099] In addition, in the present disclosure, the provision of the damping member 650 can also reduce the friction loss between the second driving member (outer sleeve) and the housing assembly when driving the cleaning member to lift and rotate.
