Description

Technical Field

[0001] This disclosure relates to a self-moving surface cleaning robot. Background Technology

[0002] Household vacuum cleaning equipment is used to clean a room by sucking up particles such as dust from the floor.

[0003] Generally, household vacuum cleaning equipment includes a side brush assembly. The rotation of the side brush assembly agitates the dust on the surface to be cleaned, and the cleaning operation is achieved by the sweeping assembly located behind the side brush assembly.

[0004] However, when the side brush assembly rotates, it often gets tangled with long, thin objects such as hair, increasing the rotational resistance of the side brush assembly and also resulting in a shorter battery life for household vacuum cleaning equipment. Moreover, these hairs tangled in the side brush assembly are difficult to remove.

[0005] In existing technologies, a single side brush is generally used to address the problem of hair entanglement in the side brush assembly. However, side brush assemblies with only one side brush have low cleaning efficiency, and the assembly can deform after long-term use, leading to a further reduction in cleaning efficiency.

[0043] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0044] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0046] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0047] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0048] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying 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 manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0049] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, 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 rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0050] Figure 1 This is a schematic diagram of the structure of a self-moving surface cleaning robot according to one embodiment of the present disclosure. Figure 2 This is a structural schematic diagram of a self-moving surface cleaning robot according to one embodiment of the present disclosure from another angle.

[0051] like Figure 1 and Figure 2 As shown, the self-moving surface cleaning robot disclosed herein can be a sweeping robot, a mopping robot, a self-moving surface cleaning robot, or a sweeping and mopping robot, etc. Among them, the self-moving surface cleaning robot can move autonomously on the surface to be cleaned to clean the surface by picking up particles located on different parts of the surface to be cleaned.

[0052] by Figure 1 and Figure 2 Taking the self-moving surface cleaning robot shown as an example, let's consider the robot's forward direction as "forward". Figure 2 In the view orientation, the self-propelled surface cleaning robot's forward direction is upward to one side. The direction away from the self-propelled surface cleaning robot's forward direction is backward, as shown in the reference. Figure 2 In the view direction, "rear" for a self-propelled surface cleaning robot refers to the side below. Correspondingly, the direction perpendicular to the front-back direction can be defined as the left-right direction.

[0053] The self-propelled surface cleaning robot may include a chassis assembly 100, which can be formed as the body of the self-propelled surface cleaning robot. The bottom of the chassis assembly 100 is provided with steering wheels 400 and driving wheels 500. The steering wheels 400 are used to control the direction of travel of the self-propelled surface cleaning robot, and the driving wheels 500 are used to drive the self-propelled surface cleaning robot forward. The steering wheels 400 are located at the front of the chassis assembly 100.

[0054] like Figure 2 As shown, the present disclosure provides two walking wheels 500, which are located approximately at the center of the chassis assembly 100 in the front-rear direction and on both sides of the chassis assembly 100 in the left-right direction. Furthermore, one steering wheel 400 is provided, which can be a caster wheel. This caster wheel is positioned at the center of the self-moving surface cleaning robot in the left-right direction and near the front end of the self-moving surface cleaning robot. Of course, the present disclosure also provides two or more steering wheels 400.

[0055] In actual use, the walking wheels 500 can be driven and rotated. By controlling the walking wheels 500 to rotate at a constant speed, the self-moving surface cleaning robot can move forward. Correspondingly, by controlling the walking wheels 500 to rotate at different speeds, the self-moving surface cleaning robot can turn.

[0056] In this disclosure, the chassis assembly 100 is further provided with a side brush assembly 200, wherein the side brush assembly 200 can be configured as one or two; Figure 2 In the implementation shown, the side brush assembly 200 is configured as one, and the side brush assembly 200 is positioned on the right side of the front end of the chassis assembly 100; thereby, by rotating the side brush assembly 200, dirt on the surface to be cleaned can be disturbed, and the surface to be cleaned can be cleaned.

[0057] In addition, a cleaning component 300 is also provided on the chassis assembly 100. The cleaning component 300 is located at the middle position in the front-rear direction of the chassis assembly 100, and its length direction is the width direction of the chassis assembly 100. More specifically, the cleaning component 300 can be a roller brush, which is rotatably connected to the chassis assembly 100, and the rotation axis of the roller brush is parallel to the surface to be cleaned, such as parallel to the ground. Figure 2 The diagram shows the specific structure when the cleaning component is a roller brush. 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.

[0058] Thus, the rotating roller brush of the cleaning component 300 can agitate the dirt on the surface to be cleaned. This dirt can be sucked into the dust box or other device by negative pressure adsorption, and the solid particles are separated in the dust box or other device, thereby achieving the cleaning operation of the surface to be cleaned.

[0059] In this disclosure, the chassis assembly 100, steering wheels 400, and walking wheels 500 can form the robot body.

[0060] Figure 3 This is a schematic diagram of the side brush assembly of a self-moving surface cleaning robot according to one embodiment of the present disclosure. Figure 4 This is a structural schematic diagram of the side brush assembly of a self-moving surface cleaning robot according to one embodiment of the present disclosure from another angle.

[0061] The side brush assembly 200 of this disclosure is disposed on the robot body and can be driven by a drive motor, so that the side brush assembly 200 can rotate relative to the chassis assembly 100 of the robot body. Although not illustrated in this disclosure, those skilled in the art should understand that the drive motor can be directly or indirectly fixed to the chassis assembly 100, and the drive motor can include an output shaft having a vertical axis of rotation (i.e., a rotation axis perpendicular to the surface to be cleaned). In this case, the side brush assembly 200 can be directly fixed to the output shaft of the drive motor, so that the drive motor can drive the side brush assembly 200 to rotate about the rotation axis. In another embodiment, the drive motor can be connected to a gearbox, in which case the gearbox has an output shaft having a vertical axis of rotation (i.e., a rotation axis perpendicular to the surface to be cleaned). The side brush assembly 200 can be directly fixed to the output shaft of the gearbox, so that the drive motor can drive the side brush assembly 200 to rotate about the rotation axis. More preferably, the rotation axis is substantially perpendicular to the surface to be cleaned.

[0062] like Figure 1 and Figure 2 As shown, the side brush assembly 200 of this disclosure includes components such as a hub 210, an arm 220, a bristle bundle 230, and a support member 240.

[0063] The hub 210 is configured to be connected to a drive motor. Specifically, the hub 210 can be detachably connected to the output shaft of the drive motor or detachably connected to the output shaft of the gearbox.

[0064] The arms 220 of this disclosure are configured as at least two, and in a preferred embodiment, the arms 220 are configured as two, which are arranged adjacent to each other.

[0065] Each arm 220 includes a connecting end connected to the hub 210 and a free end opposite to the connecting end, such that each arm 220 extends outward from the hub 210 in a direction away from the axis of rotation; and each arm 220 is angled relative to a plane perpendicular to the axis of rotation of the side brush assembly 200; that is, each arm 220 can also extend downward as it extends outward, so that the bristle bundles 230 mounted on the arm 220 can easily contact the surface to be cleaned.

[0066] Each arm 220 includes a first portion 221 and a second portion 222. One end of the first portion 221 is formed as a connecting end, whereby one end of the first portion 221 is connected to the hub 210. The other end of the first portion 221 is connected to one end of the second portion 222. The other end of the second portion 222 is formed as a free end, whereby the other end of the second portion 222 is connected to the bristle bundle 230.

[0067] Although the arm 220 is described in this disclosure by means of the first part 221 and the second part 222, this is merely for the convenience of description and does not mean that the arm 220 is formed by assembling separate parts.

[0068] Bristle bundles 230 are attached to the free ends of each arm 220 and extend outward from the free ends of the arms 220; simultaneously, since the arms 220 are tilted, the bristle bundles 230 are also tilted accordingly, so that the free ends of the bristle bundles 230 can contact the cleaning surface. Accordingly, when the drive motor drives the side brush assembly 200 to rotate, each bristle bundle 230 can be positioned such that the free ends of the bristle bundles 230 can extend beyond the front or right side of the robot body.

[0069] The support member 240 is attached between two adjacent arms 220 and is configured to prevent the bristle bundles 230 of the two adjacent arms 220 from approaching each other during operation. Therefore, in the side brush assembly 200 of this disclosure, the bristle bundles 230 provided on the multiple arms 220 effectively improve the cleaning effect on the surface to be cleaned. Furthermore, the support member 240 effectively reduces the overlap of bristle bundles 230 on the two arms 220, thereby increasing cleaning efficiency.

[0070] The support member 240 is attached between two adjacent arms 220 and is configured to prevent the bristle bundles 230 of the two adjacent arms 220 from approaching each other during operation. Therefore, in the side brush assembly 200 of this disclosure, the bristle bundles 230 provided on the multiple arms 220 effectively improve the cleaning effect on the surface to be cleaned. Furthermore, the support member 240 effectively reduces the overlap of bristle bundles 230 on the two arms 220, thereby increasing cleaning efficiency.

[0071] The support member 240 is attached to the adjacent sides of the two arms 220. Specifically, the two arms 220 have adjacent surfaces, and the two ends of the support member 240 are respectively disposed on two adjacent surfaces of the two arms 220.

[0072] More preferably, the support member 240 is attached to a position near the free ends of the two adjacent arms 220, thereby the structure formed by the arms 220 and the support member 240 of this disclosure has high strength and is not easily deformed or damaged.

[0073] In some embodiments, the two adjacent arms 220 tend to move closer to each other in the radial direction extending outward from the hub 210 away from the axis of rotation. Correspondingly, the bristle bundles 230 on the two arms 220 also tend to move closer to each other. Thus, the side brush assembly 200 of this disclosure has a better anti-tangling effect.

[0074] The side brush assembly of this disclosure may further include a reinforcing member 250, which is disposed at at least one of the connecting ends of the two arms 220 and configured to maintain an angle during operation. That is, by providing the reinforcing member 250, the structure formed by the arms 220, support member 240, and reinforcing member 250 is less prone to deformation, thereby increasing the ground pressure of the bristle bundle 230 and increasing the cleaning efficiency of the side brush assembly 200. Moreover, even if the side brush assembly of this disclosure is used for an extended period, the side brush assembly 200 will not deform or will only undergo minor deformation, without significantly reducing cleaning efficiency and improving the user experience.

[0075] The reinforcing member 250 of this disclosure is attached to the bottom of the connecting end and connects the hub 210 and the arm 220. Specifically, the support member 240 is connected to the second portion 222 of the adjacent arm 220, and the reinforcing member 250 is connected between the first portion 221 of at least one of the adjacent arms 220 and the hub 210. More preferably, the hub 210, arm 220, support member 240, and reinforcing member 250 of this disclosure can be integrally formed, i.e., formed into a whole, thereby the side brush assembly of this disclosure has better strength.
