Description

Technical Field

[0001] This application relates to the technical field of automated cleaning equipment, and particularly to a cleaning robot. Background Art

[0002] A cleaning robot, also known as an automatic sweeper, intelligent vacuum cleaner, robotic vacuum cleaner, etc., is an intelligent household appliance that can automatically complete floor cleaning work in a room by virtue of a certain degree of artificial intelligence. Generally, it uses a brushing and vacuuming method to first suck ground debris into its own dust collection box, thereby completing the function of ground cleaning.

[0003] Existing cleaning robots not only have a floor sweeping function but also a mopping function. During the working process, there will be situations where mopping is not required on some floors. Therefore, the mopping component of the cleaning robot usually has a lifting function and is lifted in scenarios where mopping is not needed.

[0004] However, in practical applications, due to the limited overall space of the cleaning robot, the lifting height of the mopping component is usually not very high, usually about 10 mm. Therefore, in some cases, its lifting height cannot meet the usage requirements. For example, on some carpeted floors, in order to prevent the mopping component from wetting the carpet, the mopping component is usually lifted at the carpet. Most existing carpets have a thickness between 5 - 25 mm. In most cases, the lifting of the mopping component still cannot completely prevent it from touching the carpet. In this situation, although it usually does not affect the movement of the cleaning robot, the moisture on the mopping component will wet the carpet. In the prior art, there is no better solution except to increase the lifting height of the mopping component. Summary of the Invention

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

[0006] To achieve the above object, the present application adopts the following technical solutions:

[0007] Provide a cleaning robot, including a cleaning component and a robot main body, and further including:

[0008] A component support for swingably mounting the cleaning component on the robot main body,

[0009] The cleaning component includes a cleaning component, which is rotatably mounted on the component support and is lifted and lowered relative to the robot main body by the swing of the component support;

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

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

[0012] Optionally, the assembly bracket and the robot main body are hinged through a first hinge structure, and the cleaning assembly is lifted and lowered by rotating and swinging the cleaning assembly around the first hinge structure by the assembly bracket.

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

[0014] Optionally, an opening driving member is arranged between the device cover plate and the assembly bracket. The opening driving member is configured to always apply a force to the device cover plate and the assembly bracket to relatively open around the rotation axis of the second hinge structure, so that the device cover plate is in the first working position.

[0015] Optionally, the device cover plate has an operation part located between the cleaning assembly and the bottom of the robot main body. When the assembly bracket is raised, the operation part abuts against the bottom of the robot main body. Under the reaction force of the bottom of the robot main body, the device cover plate and the assembly bracket approach each other, so that the device cover plate is in the second working position.

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

[0017] Optionally, the operation part is a roller rotatably installed on the connecting arm. The roller is arranged at the highest position of the device cover plate, and the highest point of the outer peripheral surface of the roller is higher than the highest point of the device cover plate.

[0018] Optionally, it further includes a rotation driving device for driving the device cover to rotate relative to the component bracket. Under the drive of the rotation driving device, the device cover switches between the first working position and the second working position.

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

[0020] The beneficial effects of the present application are as follows: In the present application, when the device cover is in the first working position, it is located between the cleaning component and the ground and the items on the ground, so that the cleaning component does not directly contact the ground and the carpet, and thus will not wet the ground and the carpet. When in the second working position, the device cover avoids the space between the cleaning component and the ground, so that the cleaning component can work normally. Thus, without increasing the lifting height of the cleaning component, the situation of the cleaning component wetting the carpet is also solved, and the overall height of the cleaning robot does not increase, avoiding the problem that the cleaning robot cannot enter positions such as under the table, under the sofa, and under the bed for cleaning due to the increased height.

Detailed implementation mode

[0030] To make the technical problems solved by this application, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of this application.

[0031] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this invention can be understood according to specific circumstances.

[0032] In this application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

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

[0034] The cleaning component 200 includes a cleaning component 200, and the cleaning component 200 is rotatably mounted on the component bracket 300 and is lifted relative to the robot main body 100 by the swing of the component bracket 300.

[0035] The device cover plate 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 plate 400 is located between the cleaning component 200 and the ground, so that the cleaning component 200 cannot directly contact the ground and the items on the ground. In the second working position, the device cover plate 400 avoids the area between the cleaning component 200 and the ground, so that the cleaning component 200 can contact the ground and the items on the ground.

[0036] In this application, when the device cover plate 400 is in the first working position, it is located between the cleaning component 200 and the ground and the items on the ground, so that the cleaning component 200 does not directly contact the ground and the carpet, and thus will not wet the ground and the carpet. In the second working position, the device cover plate 400 avoids the area between the cleaning component 200 and the ground, so that the cleaning component 200 can work normally. Thus, without increasing the lifting height of the cleaning component 200, the problem that the cleaning component 200 wets the carpet is solved, and the overall height of the cleaning robot does not increase accordingly, avoiding the problem that the cleaning robot cannot enter positions such as under the table, under the sofa, and under the bed for cleaning due to the increased height.

[0037] In this application, the first working position and the second working position of the cover plate 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 the raised state, and when the device cover plate 400 is in the second working position, the cleaning component 200 is in the lowered state.

[0038] It can be understood that when the cleaning component 200 is in the raised state, the device cover plate 400 can 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, usually the cleaning component 200 needs to perform ground cleaning work, and there is no need for the device cover plate 400 to block it.

[0039] In the embodiment of this application, the component bracket 300 and the robot main body 100 are hinged through a first hinge structure 320, and the cleaning component 200 is lifted and lowered by rotating and swinging the cleaning component 200 around the first hinge structure 320 by the component bracket 300. Specifically, the cleaning component 200 is located on one side of the hinged position between the component bracket 300 and the robot main body 100. When the component bracket 300 rotates around the first hinge structure 320, the cleaning component 200 on its side rises or falls.

[0040] Refer to 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. Both support arms 311 are L-shaped. At the outermost side where the two support arms 311 are connected to the bracket body 310, there are oppositely arranged hinge bumps 321. Corresponding to the hinge bumps 321 on the robot body 100, there is a hinge groove 322. The hinge bump 321 and the hinge groove 322 together form a first hinge structure 320. The hinge is achieved by installing the hinge bump 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 bump 321 is snapped into the hinge groove by the elastic restoring force to keep the hinge position stable.

[0041] In an alternative embodiment of the present application, the device cover 400 is also connected to the component bracket 300 by a hinge. Specifically, referring to Figure 3-5 As shown, the device cover 400 is hinged to the component bracket 300 through a second hinge structure 600. By rotating the device cover 400 relative to the component bracket 300, it switches between the first working position and the second working position.

[0042] It can be understood that although a part of the cleaning component 200 in this application can rotate by itself, its rotation axis is fixed relative to the component bracket 300, that is, the overall relative position between the cleaning component 200 and the component bracket 300 remains unchanged. Therefore, when the device cover 400 moves relative to the component bracket 300, it actually also moves relative to the cleaning component 200.

[0043] Furthermore, a spreading driving member 500 is provided between the device cover 400 and the component bracket 300. The spreading driving member 500 is configured to always apply a force to relatively spread the device cover 400 and the component bracket 300 around the rotation axis of the second hinge structure 600, so that the device cover 400 is in the first working position. The second hinge structure 600 includes a hinge shaft 610 and hinge holes 620 respectively provided on the device cover 400 and the component bracket 300. The device cover 400 and the component bracket 300 are hinged by passing the hinge shaft 610 through the two hinge holes 620.

[0044] The spreading driving member 500 applies a force to restore the device cover 400 to the second working position. The spreading driving member 500 can be in various forms. Referring to Figure 6 As shown, in an alternative embodiment of the present application, the spreading driving member 500 is a torsion spring. The torsion spring is sleeved on the hinge shaft 610. One elastic arm abuts against the device cover 400, and the other elastic arm abuts 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 an elastic restoring force is applied to the device cover 400 through the elastic force of the compression spring.

[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 repelling manner.

[0047] It should be pointed out that the specific configuration of the compression spring and the repelling magnets can be appropriately arranged by those skilled in the art according to the actual structural conditions, and will not be described in detail in this application.

[0048] In order to realize that the device cover 400 can rotate relative to the component bracket 300 during the process of the component bracket 300 being raised, in the embodiment of the present application, the device cover 400 has an operating part located between the cleaning component 200 and the bottom of the robot body 100. When the component bracket 300 is raised, the operating part abuts against the bottom of the robot body 100. Under the bottom reaction force of the robot body 100, the device cover 400 moves closer to the component bracket 300, so that the device cover 400 is in the second working position. When the operating part does not abut against the bottom of the robot body 100, under the action of the opening drive member, the device cover 400 and the component bracket 300 are relatively opened, 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 hinged to the component bracket 300 through the two connecting arms 420, and the operating part 700 is disposed on the connecting arms 420. The overall weight of the device cover 400 can be reduced by providing the connecting arms 420. At the same time, a space can be formed between the two connecting arms 420 to avoid excessive space occupation when all cover bodies 410 are used.

[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 the roller as the operating part 700, when the device cover plate 400 is abutted against the bottom of the robot body 100 and continues to move relatively, the relative sliding friction between the two can be converted into relative rolling friction, so as to avoid generating noise and reduce the wear of components.

[0052] The operating part 700 is set to be higher than the highest point of the device cover plate 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, and the rest of the device cover plate 400 is prevented from contacting the bottom of the robot body 100, avoiding wear of the device cover plate 400 and the bottom of the robot body 100 caused by friction.

[0053] Optionally, in another embodiment of the present application, it further includes a rotary driving device for driving the device cover plate 400 to rotate relative to the component bracket 300. Under the drive of the rotary driving device, the device cover plate 400 switches between the first working position and the second working position. In this structure, the relative movement between the device cover plate 400 and the bracket assembly no longer depends on the drive of the opening driving member and the extrusion of the bottom of the robot body 100. The switching between the first working position and the second working position of the device cover plate 400 can be realized by actively controlling the rotary driving device, with higher flexibility.

[0054] The working process of the device cover plate 400 in the present application is specifically as follows: Assume that in the initial state, the cleaning component 200 is in the descending state. At this time, the device cover plate 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 along with the component bracket 300, before the device cover plate 400 contacts the bottom of the robot body 100, due to the acting force of the opening driving member, the device cover plate 400 is always in an open state relative to the component bracket 300, that is, the device cover plate 400 is still in the second working position; when the cleaning component 200 continues to be lifted and the device cover plate 400 contacts the bottom of the robot body 100, the device cover plate 400 cannot continue to be lifted, while the component bracket 300 and the cleaning component 200 arranged thereon are not affected temporarily and can continue to be lifted, then the components approach each other with the device cover plate 400, and the device cover plate 400 enters the first working position. At this time, the cleaning component 200 cannot directly contact the ground and other items below it.

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

[0056] In the description of this article, it should be understood that the terms "upper", "lower", "left", "right", etc., and other directions or positional relationships are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of this application. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0057] In the description of this specification, the description with reference to the terms "an embodiment", "example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0058] In addition, it should be understood that although this specification is described according to 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. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0059] The technical principles of the present application are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the present application and cannot be interpreted as limiting the scope of protection of the present application in any way. Based on the explanations herein, those skilled in the art can think of other specific implementation methods of the present application without creative work, and these methods will fall within the scope of protection of the present application.
