Description

Technical Field

[0001] The present application relates to the technical field of automated cleaning equipment, and in particular to a cleaning robot. Background Art

[0002] A cleaning robot, also known as an automatic sweeper, smart vacuum cleaner, or robot vacuum, is a smart home appliance that uses artificial intelligence to automatically clean floors. It typically uses a brushing and vacuuming method to collect debris into its own trash collection bin, completing the cleaning process.

[0003] Existing cleaning robots not only have a sweeping function, but also a mopping function. During work, they may encounter some situations where mopping is not required. Therefore, the mopping component of the cleaning robot usually has a lifting function, which is lifted when mopping is not required.

[0004] However, in actual use, due to the limited space within a cleaning robot, the mopping assembly is typically not lifted very high, typically around 10mm. Therefore, in some cases, the platform height is insufficient to meet usage requirements. For example, on carpeted floors, the mopping assembly is typically raised above the carpet to prevent it from getting wet. However, most existing carpets are between 5mm and 25mm thick, and in most cases, even raising the mopping assembly still doesn't completely prevent it from interfering with the carpet. While this typically doesn't affect the robot's movement, moisture from the mopping assembly can wet the carpet. Existing technologies offer no better solution than raising the mopping assembly's height. Utility Model Content

[0005] The purpose of the embodiments of the present utility model is to provide a cleaning robot that can solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] A cleaning robot is provided, comprising a cleaning component and a robot body, and further comprising:

[0008] A component bracket is used to swingably mount the cleaning component on the robot body.

[0009] The cleaning assembly includes a cleaning assembly, which is rotatably mounted on the assembly bracket and is raised and lowered relative to the robot body by the swing of the assembly bracket;

[0010] The device cover is movably arranged on the component bracket relative to the cleaning component, and has a first working position and a second working position. In the first working position, the device cover is between the cleaning component and the ground, so that the cleaning component cannot directly contact the ground and objects on the ground. In the second working position, the device cover avoids the cleaning component and the ground, so that the cleaning component can contact the ground and objects on the ground.

[0011] Optionally, when the device cover is in the first working position, the cleaning assembly is in a raised state; when the device cover is in the second working position, the cleaning assembly is in a lowered state.

[0012] Optionally, the component bracket is hinged to the robot body via a first hinge structure, and the cleaning component is lifted and lowered by rotating and swinging the component bracket around the first hinge structure.

[0013] Optionally, the device cover and the component bracket are hinged via a second hinge structure, and the device cover is switched between the first working position and the second working position by rotating relative to the component bracket.

[0014] Optionally, an opening drive member is provided between the device cover and the component bracket, and the opening drive member is configured to always apply a relative opening force to the device cover and the component bracket around the rotation axis of the second hinge structure so that the device cover is in the first working position.

[0015] Optionally, the device cover has an operating part located between the cleaning component and the bottom of the robot body. When the component bracket is raised, the operating part abuts the bottom of the robot body. Under the reaction force of the bottom of the robot body, the device cover moves closer to the component bracket so that the device cover is in the second working position.

[0016] Optionally, the device cover includes a cover body and two connecting arms arranged at both ends of the cover body, the device cover is hinged to the component bracket through the two connecting arms, and the operating part is arranged on the connecting arms.

[0017] Optionally, the operating part is a roller rotatably mounted on the connecting arm, the roller is arranged at the highest position of the device cover, and the highest point of the outer circumference of the roller is higher than the highest point of the device cover.

[0018] Optionally, a rotation drive device is further included for driving the device cover to rotate relative to the component bracket, and the device cover is switched between the first working position and the second working position under the drive of the rotation drive device.

[0019] Optionally, the opening driving member is a torsion spring, a spring, or repelling magnets respectively provided on the device cover and the component bracket.

[0020] The beneficial effects of the present application are as follows: in the present application, the device cover is located between the cleaning component and the ground and objects on the ground in the first working position, so that the cleaning component does not directly contact the ground and carpet, and therefore does not wet the ground and carpet; and in the second working position, the device cover avoids the cleaning component and the ground to enable the cleaning component to work normally. Thus, without increasing the lifting height of the cleaning component, the problem of the cleaning component wetting the carpet is also solved, and the overall height of the cleaning robot is not increased. This avoids the problem that the cleaning robot cannot enter places such as tables, sofas, and beds for cleaning due to the increase in height. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0031] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0032] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0033] like Figure 1-6 As shown, the embodiment of the present application provides a cleaning robot, comprising a cleaning component 200 and a robot body 100, and further comprising: a component bracket 300 for swingably mounting the cleaning component 200 on the robot body 100,

[0034] The cleaning assembly 200 includes a cleaning assembly 200 , which is rotatably mounted on the assembly bracket 300 and is raised and lowered relative to the robot body 100 by the swing of the assembly bracket 300 ;

[0035] The device cover 400 is movably arranged on the component bracket 300 relative to the cleaning component 200, and has a first working position and a second working position. In the first working position, the device cover 400 is between the cleaning component 200 and the ground, so that the cleaning component 200 cannot directly contact the ground and objects on the ground. In the second working position, the device cover 400 avoids the cleaning component 200 and the ground, so that the cleaning component 200 can contact the ground and objects on the ground.

[0036] In the present application, the device cover 400 is located between the cleaning component 200 and the ground and objects on the ground in the first working position, so that the cleaning component 200 does not directly contact the ground and the carpet, and therefore does not wet the ground and the carpet. In the second working position, the device cover 400 avoids the cleaning component 200 and the ground to enable the cleaning component 200 to work normally. Thus, without increasing the lifting height of the cleaning component 200, the problem of the cleaning component 200 wetting the carpet is also solved. The overall height of the cleaning robot does not increase as a result, avoiding the problem of the cleaning robot being unable to enter places such as tables, sofas, and beds for cleaning due to the increase in height.

[0037] The first working position and the second working position of the cover plate described in this application are related to the working position of the cleaning component 200. Specifically, when the device cover plate 400 is in the first working position, the cleaning component 200 is in a raised state; when the device cover plate 400 is in the second working position, the cleaning component 200 is in a lowered state.

[0038] It can be understood that only when the cleaning component 200 is in the raised state can the device cover 400 enter the first working position and be located between the cleaning component 200 and the carpet. When the cleaning component 200 is in the lowered state, the cleaning component 200 usually needs to perform floor cleaning work without the need for the device cover 400 to cover it.

[0039] In the embodiment of the present application, the assembly bracket 300 is hingedly connected to the robot body 100 via a first hinge structure 320. The cleaning assembly 200 is raised or lowered by rotating the assembly bracket 300 about the first hinge structure 320. Specifically, the cleaning assembly 200 is located to one side of the hinged connection between the assembly bracket 300 and the robot body 100. When the assembly bracket 300 rotates about the first hinge structure 320, the cleaning assembly 200 located to its side rises or falls.

[0040] Reference Figure 3 、 4As shown, the component bracket 300 includes a bracket body 310 and support arms 311 located at both ends of the bracket body 310. The two support arms 311 are L-shaped, and hinge protrusions 321 are relatively set on the farthest side surfaces where the two support arms 311 are connected to the bracket body 310. A hinge groove 322 is set on the robot body 100 corresponding to the hinge protrusion 321. The hinge protrusion 321 and the hinge groove 322 together constitute a first hinge structure 320, which is hinged by installing the hinge protrusion 321 in the hinge groove 322. In this application, the support arm 311 is an elastic structure, which can be relatively opened, and then the hinge protrusion 321 is clamped in the hinge groove by the elastic restoring force to keep the hinge position stable.

[0041] In an optional embodiment of the present application, the device cover 400 and the component bracket 300 are also connected in a hinged manner. Specifically, refer to Figure 3-5 As shown, the device cover 400 and the component bracket 300 are hinged via a second hinge structure 600 , and the device cover 400 is switched between the first working position and the second working position by rotating relative to the component bracket 300 .

[0042] It can be understood that although the cleaning component 200 in the present application is partially rotatable, its rotation axis is fixed relative to the component bracket 300, that is, the overall relative position of the cleaning component 200 and the component bracket 300 is fixed. Therefore, when the device cover 400 moves relative to the component bracket 300, it actually moves relative to the cleaning component 200.

[0043] Furthermore, an opening drive member 500 is provided between the device cover 400 and the assembly bracket 300. The opening drive member 500 is configured to constantly apply a force to the device cover 400 and the assembly bracket 300 to open relative to each other about the rotation axis of the second hinge structure 600, so as to maintain the device cover 400 in the first working position. The second joint structure 600 includes a hinge axis 610 and hinge holes 620 respectively provided on the device cover 400 and the assembly bracket 300. The hinge axis 610 passes through the two hinge holes 620 to achieve the hinge connection between the device cover 400 and the assembly bracket 300.

[0044] The opening drive member 500 applies a force to the device cover 400 to restore it to the second working position. The opening drive member 500 can be in various forms. Figure 6 As shown, in an optional embodiment of the present application, the opening drive member 500 is a torsion spring, which is sleeved on the hinge shaft 610, with one elastic arm abutting against the device cover 400 and the other elastic arm abutting against the component bracket 300.

[0045] In other embodiments, the opening driving member 500 may also be a compression spring disposed between the device cover 400 and the component bracket 300 , and the elastic force of the compression spring applies an elastic restoring force to the device cover 400 .

[0046] In another optional embodiment, the opening driving member 500 is a pair of magnets, and the two magnets are respectively disposed on the device cover 400 and the component bracket 300 in a manner that repels each other.

[0047] It should be noted that those skilled in the art can make appropriate arrangements for the specific configuration of the compression spring and the repelling magnets according to the actual structural conditions, and they will not be described in detail in this application.

[0048] In order to enable the device cover 400 to rotate relative to the component support 300 during the raising process of the component support 300, in the embodiment of the present application, the device cover 400 has an operating portion located between the cleaning component 200 and the bottom of the robot body 100. When the component support 300 is raised, the operating portion abuts the bottom of the robot body 100. Under the reaction force of the bottom of the robot body 100, the device cover 400 moves closer to the component support 300, so that the device cover 400 is in the second working position. When the operating portion does not abut the bottom of the robot body 100, the device cover 400 and the component support 300 are opened relative to each other under the action of the opening drive member, and the device cover 400 is in the first working position.

[0049] Specifically, refer to Figure 4 、 5 As shown, the device cover 400 includes a cover body 410 and two connecting arms 420 disposed at both ends of the cover body 410. The device cover 400 is hingedly connected to the component bracket 300 via the two connecting arms 420, and the operating unit 700 is disposed on the connecting arms 420. The provision of the connecting arms 420 can reduce the overall weight of the device cover 400. At the same time, a space can be created between the two connecting arms 420 to avoid excessive space occupation when the cover body 410 is used alone.

[0050] Preferably, refer to Figure 3 、 6 As shown, the operating part 700 in the embodiment of the present application is a roller rotatably mounted on the connecting arm 420, the roller is arranged at the highest position of the device cover 400, and the highest point of the outer peripheral surface of the roller is higher than the highest point of the device cover 400.

[0051] By setting a roller as the operating part 700, the relative sliding friction between the device cover 400 and the bottom of the robot body 100 when the two continue to move relative to each other can be converted into relative rolling friction, thereby avoiding noise and reducing wear on components.

[0052] The operating part 700 is set to be higher than the highest point of the device cover 400, so that the operating part 700 first contacts the bottom of the robot body 100, so that the operating part 700 can work normally, avoiding the rest of the device cover 400 from contacting the bottom of the robot body 100, and avoiding friction causing wear on the bottom of the device cover 400 and the robot body 100.

[0053] Optionally, in another embodiment of the present application, a rotation drive device is further included for driving the device cover 400 to rotate relative to the component bracket 300. The device cover 400 is driven by the rotation drive device to switch between the first working position and the second working position. In this structure, the relative movement between the device cover 400 and the bracket assembly no longer depends on the drive of the opening drive member and the squeezing of the bottom of the robot body 100. The switching of the device cover 400 between the first working position and the second working position can be achieved by actively controlling the rotation drive device, which is more flexible.

[0054] The working process of the device cover 400 in the present application is specifically as follows: assuming that in the initial state, the cleaning component 200 is in a descending state, at this time the device cover 400 is in the second working position, and the cleaning component 200 can directly contact the ground for cleaning work. When the cleaning component 200 is lifted with the component bracket 300, when the device cover 400 does not contact the bottom of the robot body 100, due to the force of the opening drive member, the device cover 400 is always in an open state relative to the component bracket 300, that is, the device cover 400 is still in the second working position; when the cleaning component 200 continues to be lifted, the device cover 400 contacts the bottom of the robot body 100, and the device cover 400 cannot continue to be lifted, and the component bracket 300 and the cleaning component 200 arranged thereon are temporarily not affected and can continue to be lifted, then the components and the device cover 400 move closer to each other, and the device cover 400 enters the first working position. At this time, the cleaning component 200 cannot directly contact the ground and other objects below it.

[0055] In this state, when the control component bracket 300 swings downward, the cleaning component 200 falls and the opening force of the opening drive member is not released, the device cover 400 does not fall, and the device cover 400 and the component bracket 300 are relatively opened, so that the device cover 400 changes to the second working position until the cleaning component 200 falls and contacts the ground. The device cover 400 remains in the second working position.

[0056] In the description herein, it should be understood that the terms "upper," "lower," "left," "right," and other positions or relationships are used solely for ease of description and simplified operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

In this specification, schematic representations of these terms do not necessarily refer to the same embodiment or example.

[0058] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
