As another example, at least one of a, b, or c can be represented as: a, b, c, a+b, a+c, b+c, a+b+c, where a, b, and c can be single or multiple.

[0031] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0032] like Figure 1 , Figure 4 and 6 As shown, this application embodiment provides a cleaning device 200, which includes a housing structure 100 and a cleaning module 90 disposed on the housing structure 100. The housing structure 100 is used to move on the surface to be cleaned, and the cleaning module 90 cleans the surface to be cleaned during the movement with the housing structure 100.

[0033] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the housing structure 100 includes a main housing (not shown) and a first component 10 and a second component 20 disposed on the main housing. The first component 10 and the second component 20 are movable relative to each other, so that the housing structure 100 has different states. For example, when the first component 10 and the second component 20 are close together, the housing structure 100 is defined as being in a retracted state; when the first component 10 and the second component 20 are far apart, the housing structure 100 is defined as being in an extended state.

[0034] The specific type of the cleaning device 200 is not limited, and correspondingly, the specific functions and forms of the first component 10 and the second component 20 are not limited. In some embodiments, the cleaning device 200 is a window cleaning machine, and the first component 10 and the second component 20 can be suction cups of the window cleaning machine. The suction cups are used to allow the housing structure 100 to adhere to and be held on a surface such as glass. The two suction cups are relatively far apart and close together, so that the window cleaning machine can cross window frames, etc. In other embodiments, the cleaning device 200 can be a self-moving floor cleaning device, and the first component 10 and the second component 20 can be two moving parts of the floor cleaning device 200, such as moving wheels, support legs, etc. The two moving parts are relatively far apart and close together, so that the floor cleaning device 200 can cross obstacles or move. In some embodiments, the cleaning module 90 can be disposed on the first component 10 and / or the second component 20. Figure 1 As shown, in some embodiments of this application, the cleaning module 90 is disposed in the first component 10. In other embodiments, there may be multiple cleaning modules 90, which are independently connected to the first component 10 and the second component 20. The relative distance between the first component 10 and the second component 20 causes the corresponding cleaning module 90 to move away synchronously, so that the cleaning module 90 can clean a more distant location.

[0035] Among the different types of cleaning equipment 200, the cleaning modules 90 take different forms, including but not limited to roller brushes, rollers, and round mops.

[0036] The relative movement of the first component 10 and the second component 20 can take many forms. For example, the second component 20 can reciprocate along a straight line relative to the first component 10. Or, the second component 20 can rotate relative to the first component 10. Or, the second component 20 can have multiple degrees of freedom of movement relative to the first component 10.

[0037] Next, taking a window cleaning machine as an example, the cleaning equipment 200 and its housing structure 100 of this application will be described.

[0038] As mentioned above, when the first component 10 and the second component 20 are relatively far apart, there is a problem of insufficient rigidity and instability between the unfolded shell structure 100, which can easily cause safety problems of the shell structure 100.

[0039] Taking the first component 10 as the first suction cup 11 and the second component 20 as the second suction cup 21 as an example, the explanation is as follows: Figure 1 and Figure 6 As shown.

[0040] like Figure 1 , Figure 4 and Figure 6 As shown in the embodiments of this application, in the housing structure 100, the first suction cup 11 is fixedly disposed on the main housing; as Figure 4 and 6 As shown, the second suction cup 21 is disposed on the main housing and is movable relative to the first suction cup 11. The second suction cup 21 has a retracted position close to the first suction cup 11 (e.g., Figure 1 (as shown) and the unfolded position away from the first suction cup 11 (as shown) Figure 6 (As shown); the second suction cup 21 can be in an intermediate position between the retracted position and the extended position, as shown. Figure 4 As shown.

[0041] like Figure 2 , Figure 3 , Figure 13 and Figure 14 As shown in the embodiments of this application, the housing structure 100 further includes an auxiliary component 30. The auxiliary component 30 includes a connecting portion 32 and a first limiting portion 33 that are fixedly connected to each other. One of the first suction cup 11 and the second suction cup 21 is provided with a first mating portion 140, and the connecting portion 32 is fixedly disposed on the other of the first suction cup 11 and the second suction cup 21. Figure 8 As shown, when the second suction cup 21 is in the unfolded position, the first limiting part 33 and the first mating part 140 form a fixed connection; as Figure 3 As shown, when the second suction cup 21 is in the retracted position, the first limiting part 33 moves away from the first mating part 140.

[0042] The first limiting part 33 and the first mating part 140 can have various limiting and mating methods. For example, the first limiting part 33 and the first mating part 140 can be a mechanical structure with a concave-convex fit; or, the first limiting part 33 and the first mating part 140 can be a sufficiently stable and easily separable magnetic attraction fit; or, the first limiting part 33 and the first mating part 140 can also be a sufficiently stable and easily separable negative pressure adsorption fit, etc. The key is that the two parts can be in a mutually connected and mutually separated state depending on the position of the second suction cup 21.

[0043] In some embodiments, such as Figure 3 and Figure 8 As shown, one of the first limiting part 33 and the first mating part 140 is a limiting groove (defined here as the first limiting groove 14), and the other is a limiting block (defined here as the first limiting block 36).

[0044] When the second suction cup 21 is in the unfolded position, the first limiting block 36 is in the first limiting groove 14, thereby fixing the auxiliary component 30 in the first limiting groove 14. This makes the first suction cup 11 and the second suction cup 21 form a rigid fixed support through the auxiliary component 30, thereby enabling the second suction cup 21 to be stably held in its unfolded position.

[0045] The cleaning device 200 and its housing structure 100 provided in this application embodiment have an auxiliary component 30 disposed between the first suction cup 11 and the second suction cup 21. The auxiliary component 30 includes a connecting part 32 and a first limiting part 33 that are fixedly connected. One of the first suction cup 11 and the second suction cup 21 is provided with a first mating part 140, and the connecting part 32 is fixedly disposed on the other of the first suction cup 11 and the second suction cup 21. When the second suction cup 21 is in the unfolded position, the first limiting part 33 and the first mating part 140 are fixedly connected, so that the auxiliary component 30 is fixedly connected to both the first suction cup 11 and the second suction cup 21. This provides additional fixed support between the first suction cup 11 and the second suction cup 21, so that the first suction cup 11 and the second suction cup 21 maintain a stable relative unfolded state, improve the unfolding rigidity and stability of the housing structure 100, and ensure the working effect and working safety of the cleaning device 200.

[0046] In some embodiments of this application, taking the main housing as a reference, the first suction cup 11 can be configured to move away from and towards the second suction cup 21, or the second suction cup 21 can be configured to move away from and towards the first suction cup 11. Here, we will illustrate this by taking the configuration of the second suction cup 21 being able to move away from and towards the first suction cup 11 as an example. Figure 1 As shown, in some embodiments of this application, the housing structure 100 further includes a drive assembly 40, which is disposed on the first suction cup 11 and connected to the second suction cup 21, for driving the second suction cup 21 to move relative to the first suction cup 11. Specifically, the output end of the drive assembly 40 is connected to the second suction cup 21. As mentioned above, drive assemblies 40 with different structures can drive the second suction cup 21 to move in different ways.

[0047] In some embodiments of this application, such as Figure 1 , Figure 4 and Figure 6 As shown, the drive assembly 40 is used to drive the second suction cup 21 to move along the first direction X, moving away from and towards the first suction cup 11. Optionally, as... Figure 4 , Figure 5 and Figure 7 As shown, the drive assembly 40 includes a motor 41, a lead screw 42, and a nut 43. The motor 41 is fixedly mounted on the first suction cup 11. The lead screw 42 is coaxially connected to the output shaft of the motor 41 and is rotatably mounted on the second suction cup 21. The nut 43 is fixedly mounted on the second suction cup 21 and engages with the lead screw 42. This allows the second suction cup 21 to move along the axial direction of the lead screw 42. In other alternative embodiments, the drive assembly 40 can convert the torque of the motor 41 into linear motion of the second suction cup 21 through a transmission method such as a gear and rack pair; further examples will not be provided.

[0048] In some embodiments of this application, such as Figure 2 , Figure 5, Figure 7 and Figure 8 As shown, the connecting part 32 is fixedly connected to the second suction cup 21, and the first mating part 140 is disposed on the first suction cup 11. This arrangement aims to improve the connection stability between the auxiliary component 30 and the second suction cup 21. The overall movement of the auxiliary component 30 and the second suction cup 21 relative to the first suction cup 11 helps reduce the shaking of the second suction cup 21 in its unfolded state. This will be explained using this as an example below. In other alternative embodiments, by setting the dimensions of the first limiting part 33 and the first mating part 140 to ensure maximum stability, the connecting part 32 can also be fixedly connected to the first suction cup 11.

[0049] In some embodiments of this application, such as Figure 2 , Figure 3 , Figure 13 and Figure 14 As shown, the auxiliary component 30 includes an auxiliary rod 31, which is arranged along the first direction X. One end of the auxiliary rod 31 is provided with the aforementioned connecting part 32. The auxiliary rod 31 and the connecting part 32 are in a relatively fixed connection relationship. The first limiting part 33 includes a first limiting block 36 provided on the auxiliary rod 31.

[0050] Optionally, such as Figure 13 and Figure 14 As shown, the connection part 32 provided at one end of the auxiliary rod 31 means that one end of the auxiliary rod 31 can be directly used as or include the connection part 32. The size of the connection part 32 can be the same as or substantially the same as the size of other positions of the auxiliary rod 31. Alternatively, the connection part 32 can be fixedly provided at one end of the auxiliary rod 31 as an additional block structure, as long as the connection part 32 can be fixedly connected to the second suction cup 21.

[0051] like Figure 13 , Figure 14 As shown, in some embodiments, the size of the first limiting block 36 is larger than the size of other positions on the auxiliary rod 31, so that other positions on the auxiliary rod 31 are not restricted when passing through the first mating part 140. Specifically, the first limiting block 36 can be a block structure integrally formed with the auxiliary rod 31, or it can be a structure separately manufactured from the auxiliary rod 31 and fixed to the auxiliary rod 31. For example, in Figure 13 and Figure 14 As shown, both the first limiting block 36 and the auxiliary rod 31 are provided with pin holes 37 opened in a direction perpendicular to the axial direction (first direction X) of the auxiliary rod 31. The first limiting pin 38 is inserted into the two aligned pin holes 37 to fix the first limiting block 36 to the auxiliary rod 31. In other optional embodiments, the first limiting block 36 and the auxiliary rod 31 can also be fixed in other ways, which will not be described in detail.

[0052] The shape of the auxiliary rod 31 is not limited; it can be a round rod, a rectangular rod, an elliptical rod, or any other shape. In the auxiliary assembly 30, the number of auxiliary rods 31 can be one or more. In some optional embodiments, such as... Figure 2 , Figure 13 and Figure 14 As shown, the auxiliary component 30 includes a plurality of auxiliary rods 31 arranged parallel to each other. Taking two as an example, the two auxiliary rods 31 are arranged at intervals in a plane perpendicular to the first direction X. The plurality of auxiliary rods 31 are connected together to the first limiting block 36.

[0053] In some embodiments of this application, such as Figure 3 , Figure 8 , Figure 9 and Figure 10 As shown, a first guide surface 143 is provided on the side of the first limiting groove 14 facing away from the second suction cup 21. In the direction away from the second suction cup 21, the first guide surface 143 is a gradually expanding surface. The purpose of this arrangement is that the first guide surface 143 can guide the first limiting block 36 when it enters the first limiting groove 14, making it easy for the first limiting block 36 to align with the first limiting groove 14. Alternatively, in other embodiments, the first guide surface 143 can be formed on the side of the first limiting block 36 facing the second suction cup 21, and in the direction facing the second suction cup 21, the first guide surface 143 is a gradually contracting surface. This also provides sliding guidance between the first limiting block 36 and the first limiting groove 14.

[0054] In some embodiments of this application, such as Figure 10 As shown, the inner circumferential surface of the first limiting groove 14 is provided with a plurality of guide ribs 144. The guide ribs 144 are arranged at intervals along the direction surrounding the auxiliary rod 31 and are set along the first direction X. The first guide surface 143 is provided on the side of the guide ribs 144 opposite to the second suction cup 21. In this case, the first limiting block 36 does not abut against the entire inner circumferential surface of the first limiting groove 14, but only against the inner side surface of the guide ribs 144. The purpose of this arrangement is to reduce the influence of the inner wall shape deviation of the first limiting groove 14 on the sliding of the first limiting block 36. Conversely, it can ensure that the first limiting groove 14 and the first limiting block 36 can fit as closely and tightly as possible, so as to improve the connection stability between the two and avoid large shaking between them.

[0055] In some embodiments of this application, such as Figure 1 and Figure 3As shown, the first suction cup 11 includes a first suction cup body 111 (i.e., the first component body of the first component 10) and a first fixing member 112 fixedly connected to the first suction cup body 111. A first limiting groove 14 is disposed in the first fixing member 112 or between the first fixing member 112 and the first suction cup body 111. The purpose of this arrangement is to define at least a portion of the first limiting groove 14 by means of the first fixing member 112, which simplifies the structure of the first suction cup body 111 and facilitates the processing and forming of the first suction cup body 111 and the first limiting groove 14. The first fixing member 112 can be separately manufactured and fixedly connected to the first suction cup body 111.

[0056] In some embodiments of this application, such as Figure 3 , Figure 8 and Figure 9 As shown, the first limiting groove 14 includes a first groove portion 141 disposed on the first suction cup body 111 and a second groove portion 142 disposed on the first fixing member 112. The first groove portion 141 and the second groove portion 142 are opposite to and connected in a direction perpendicular to the first direction X. The purpose of this arrangement is that the sides of the first suction cup body 111 and the first fixing member 112 that are close to each other are each recessed, thereby defining a portion of the first limiting groove 14. Therefore, the first suction cup body 111 and the first fixing member 112 can be easily processed and shaped.

[0057] The shapes of the first limiting block 36 and the first limiting groove 14 are not limited. For example Figure 13 and Figure 14 As shown, in some embodiments of this application, the first limiting block 36 is arched, and the auxiliary rod 31 passes through the arched first limiting block 36.

[0058] Depending on the shape of the first limiting groove 14, the aforementioned guide rib 144 can be disposed on the inner wall surface of the first groove portion 141, or, as... Figure 10 As shown, it can be provided on the inner wall surface of the second groove 142, or it can be provided on the inner wall surface of both the first groove 141 and the inner wall surface of the second groove 142.

[0059] In some embodiments of this application, such as Figure 3 and Figure 8 As shown, along the first direction X, the end of the first groove 141 facing away from the second suction cup 21 is not flush with the end of the second groove 142 facing away from the second suction cup 21. Alternatively, the first groove 141 may protrude beyond the second groove 142, or the second groove 142 may protrude beyond the first groove 141. This arrangement is intended to allow a portion of the first limiting block 36 to first enter the first limiting groove 14, and then the entire block enters the first limiting groove 14, facilitating smooth sliding of the first limiting block 36 along the first direction X.

[0060] In some embodiments of this application, such as Figure 2 , Figure 3 and Figure 8 As shown, the auxiliary component 30 also includes a second limiting part 34 fixedly connected to the connecting part 32. Taking the fixed connection of the second limiting part 34 to the second suction cup 21 as an example, the first suction cup 11 is also provided with a second mating part 150; as Figure 3 As shown, when the second suction cup 21 is in the retracted position, the second limiting part 34 and the second mating part 150 form a fixed connection, as... Figure 8 As shown, when the second suction cup 21 is in the unfolded position, the second limiting part 34 moves away from the second mating part 150.

[0061] The second limiting part 34 and the second mating part 150 can have various limiting and mating methods. For example, the second limiting part 34 and the second mating part 150 can be a mechanical structure with a concave-convex fit; or, the second limiting part 34 and the second mating part 150 can be a sufficiently stable and easily separable magnetic attraction fit; or, the second limiting part 34 and the second mating part 150 can also be a sufficiently stable and easily separable negative pressure adsorption fit, etc. As long as the two can be in a mutually connected and mutually separated state according to the position of the second suction cup 21, it is acceptable.

[0062] In some embodiments of this application, such as Figure 2 , Figure 3 , Figure 7 As shown, one of the second limiting part 34 and the second mating part 150 is a limiting groove (defined here as the second limiting groove 15), and the other is a limiting block (defined here as the second limiting block 340).

[0063] The purpose of this arrangement is to provide further support for the second suction cup 21 in the retracted position, so that the housing structure 100 can be further stabilized when it is in the retracted state.

[0064] In some embodiments of this application, such as Figure 13 and Figure 14 As shown, the other end of the auxiliary rod 31 includes a second limiting block 340. Specifically, this means that the other end of the auxiliary rod 31 can directly serve as or include the second limiting block 340; or, the second limiting part 34 can also be a block-shaped structure (second limiting block 340) fixedly disposed at the other end of the auxiliary rod 31, wherein the second limiting block 340 can be integrally formed with the auxiliary rod 31, or it can be separately manufactured and fixed to the other end of the auxiliary rod 31. In other optional embodiments, the second limiting groove 15 can be formed at the other end of the auxiliary rod 31, and the second limiting block 340 can be disposed on the first suction cup 11.

[0065] The method of fixing the auxiliary rod 31 to the connecting part 32 and the body of the second suction cup 21 is not limited. For example Figure 15As shown, in some optional embodiments, the other end of the auxiliary rod 31 is fixed to the second suction cup 21 by the second limiting pin 39 passing through both the auxiliary rod 31 and the second suction cup 21.

[0066] In some embodiments, the auxiliary rod 31 on the auxiliary component 30 is provided with a first limiting part 33 and a second limiting part 34, which are solid structures or even protruding structures, and the first suction cup 11 is provided with the two limiting grooves mentioned above. The purpose of this arrangement is to simplify the structure of the auxiliary rod 31 and to make the processing and manufacturing of the auxiliary rod 31 as simple as possible.

[0067] In some embodiments of this application, such as Figure 11 As shown, a second guide surface 151 is provided on the side of the second limiting groove 15 facing the second suction cup 21. In the direction facing the second suction cup 21, the second guide surface 151 is a gradually expanding surface. The purpose of this design is that, as the second suction cup 21 gradually retracts, the gradually expanding design of the second guide surface 151 guides the second limiting part 34 of the auxiliary rod 31 to gradually enter the second limiting groove 15, making the retraction of the second suction cup 21 relative to the first suction cup 11 smoother. Specifically, as shown... Figure 11 and Figure 12 As shown, the second limiting groove 15 is a flared opening facing the second suction cup 21.

[0068] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the first suction cup 11 further includes a second fixing member 113 fixedly connected to the first suction cup body 111. The second fixing member 113 is provided with a second limiting groove 15, or the second fixing member 113 and the first suction cup body 111 are provided with the aforementioned second limiting groove 15. The purpose of this arrangement is to limit at least a portion of the second limiting groove 15 by means of the second fixing member 113, which simplifies the structure of the first suction cup body 111 and facilitates the processing and forming of the first suction cup body 111 and the second limiting groove 15. Optionally, the second fixing member 113 can be separately manufactured and fixedly connected to the first suction cup body 111. In some embodiments of this application, the second limiting groove 15 can be provided on the second fixing member 113.

[0069] In some embodiments of this application, such as Figure 12As shown, the outer surface of the second fixing member 113 is provided with multiple irregularly shaped protrusions 1130, and the first suction cup body 111 is provided with an irregularly shaped groove (not shown) that matches the shape of the irregularly shaped protrusions 1130. The irregularly shaped protrusions 1130 are located in the irregularly shaped groove and are press-fitted with the inner wall of the irregularly shaped groove. Through the cooperation of the irregularly shaped groove and the irregularly shaped protrusions 1130, the second fixing member 113 can be stably installed on the first suction cup body 111. Of course, based on this, the second fixing member 113 and the first suction cup body 111 can also be further fixedly connected by locking components (including but not limited to screws). The specific shape of the irregularly shaped groove and the irregularly shaped protrusions 1130 is not limited to triangles, semicircles, cylinders, etc.

[0070] In some embodiments of this application, such as Figure 2 , Figure 5 and Figure 7 As shown, the housing structure 100 also includes one or more bearings 50, such as Figure 2 As shown, the first suction cup body 111 is provided with a third fixing groove 1111, and each bearing 50 is disposed in the third fixing groove 1111. The auxiliary component 30 passes through the bearing 50. Specifically, each auxiliary rod 31 passes through the bearing 50. During the unfolding and retraction of the second suction cup 21, the bearing 50 is used to support the sliding of the auxiliary rod 31. While reducing the sliding friction of the auxiliary rod 31, it keeps the auxiliary rod 31 sliding along the first direction X, and avoids the sliding direction of the auxiliary rod 31 from deviating.

[0071] like Figure 2 As shown, in some embodiments, the first suction cup body 11 is provided with a first fixing groove 1110. Specifically, the first suction cup body 111 is provided with a first fixing groove 1110, and the motor 41 is fixedly installed in the first fixing groove 1110.

[0072] like Figure 2 As shown, in some embodiments, the second suction cup 21 is provided with a second fixing groove 210, and the nut 43 is fixedly disposed in the second fixing groove 210.

[0073] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
