[0049] Please see Figures 1-3 , Figure 1 Schematic diagram of the structure of the cleaning device 100 provided in some embodiments of this application Figure 1 , Figure 2 Schematic diagram of the structure of the cleaning device 100 provided in some embodiments of this application Figure 2 , Figure 3 This is a schematic diagram illustrating the movement of a cleaning device 100 provided in some embodiments of this application. For ease of description, please refer to... Figure 2 In this embodiment of the application, the length direction of the cleaning device 100 is defined as the X-axis direction, the width direction of the cleaning device 100 is defined as the Y-axis direction, and the height direction of the cleaning device 100 is defined as the Z-axis direction, wherein the X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other.

[0050] It is worth noting that the qualifying terms for parallel and / or perpendicular positional relationships mentioned in this embodiment are all relative to the current technological level, and not absolute and strict definitions in a mathematical sense. Slight deviations are allowed; approximations of parallelism and perpendicularity are acceptable. Furthermore, this embodiment uses directional terms such as "top," "bottom," "left," "right," "front," and "rear" when describing the cleaning equipment 100. The orientation is primarily based on the location of the cleaning equipment 100 within the attached... Figure 1The orientation of the display is described as follows: the positive direction of the X-axis is "right", the negative direction of the X-axis is "left", the positive direction of the Y-axis is "front", the negative direction of the Y-axis is "back", the positive direction of the Z-axis is "top", and the negative direction of the Z-axis is "bottom".

[0051] Please see Figure 1 The cleaning equipment 100 provided in this application embodiment can be a window cleaning machine or other types of automatic cleaning equipment, and this application does not limit it.

[0052] In some embodiments, see Figure 1 The cleaning device 100 includes a housing 20, a first suction cup 30, and a second suction cup 40. The first suction cup 30 and the second suction cup 40 are used to attach the cleaning device 100 to the surface to be cleaned. The first suction cup 30 and the second suction cup 40 are vacuum suction cups. By extracting the air between the suction cup and the surface to be cleaned, the suction cup can be firmly attached to the surface to be cleaned.

[0053] In one exemplary scenario, please refer to Figure 3 The first suction cup 30 is controlled to enter the adsorption state, while the second suction cup 40 remains in the non-adsorption state. At this time, the first suction cup 30 is adsorbed onto the surface to be cleaned, and the second suction cup 40 is in a movable state. By controlling the cleaning device 100 to rotate around the axis of the first suction cup 30, the second suction cup 40 can rotate and swing around the axis of the first suction cup 30. For convenience, the second suction cup 40 after swinging is referred to as the second suction cup 40'. Then, the second suction cup 40' is switched to the adsorption state, and the adsorption state of the first suction cup 30 is released. At this time, the second suction cup 40' is fixed to the surface to be cleaned, and the first suction cup 30 is in a movable state. By controlling the cleaning device 100 to rotate around the axis of the second suction cup 40', the first suction cup 30 can rotate and swing around the axis of the second suction cup 40'. For convenience, the first suction cup 30 after swinging is referred to as the first suction cup 30'. Repeating the above process allows the cleaning device 100 to move on the surface to be cleaned.

[0054] Please see Figure 1 The cleaning device 100 provided in this application embodiment also includes a cleaning module 10, which is used to clean the surface to be cleaned. That is, when the cleaning device 100 moves on the surface to be cleaned, the surface to be cleaned can be cleaned by the cleaning module 10.

[0055] Please see Figures 4-8 , Figure 4 Schematic diagram of the structure of the cleaning module 10 provided in some embodiments of this application Figure 1 , Figure 5 Top view schematic diagram of cleaning module 10 provided in some embodiments of this application Figure 1 , Figure 6Top view schematic diagram of cleaning module 10 provided in some embodiments of this application Figure 2 , Figure 7 This is a schematic diagram illustrating the movement of existing related cleaning equipment 100. Figure 8 This is a schematic diagram illustrating the movement of a cleaning device 100 provided in some embodiments of this application.

[0056] Please see Figure 4 The cleaning module 10 provided in this application embodiment includes a support 1, a cleaning unit 2, an intermediate frame 3 and a first elastic part 4, wherein the intermediate frame 3 connects the support 1 and the cleaning unit 2.

[0057] The cleaning unit 2 is oscillatingly connected to the support 1 via the intermediate frame 3, meaning that the cleaning unit 2 can oscillate relative to the support 1, and the oscillation direction of the cleaning unit 2 is parallel to the surface to be cleaned. The first elastic part 4 is provided on the intermediate frame 3, and the first elastic part 4 is used to reset the cleaning unit 2 when it oscillates.

[0058] The swing direction of cleaning unit 2 is parallel to the surface to be cleaned, that is, the swing axis of intermediate frame 3 is perpendicular to the surface to be cleaned. Alternatively, the swing axis of intermediate frame 3 may be perpendicular to the surface to be cleaned. Figure 4 There is a small included angle in the Z-axis direction.

[0059] Please see Figure 5 and Figure 6 , Figure 5 and Figure 6 The diagrams show the cleaning unit 2 in a first position and a second position, respectively. The first position represents the initial state of the cleaning unit 2. When force is applied to the cleaning unit 2, it can swing relative to the support 1 to a position such that... Figure 6 As shown in the diagram, when the cleaning unit 2 swings from the first position to the second position, the first elastic part 4 is compressed; when the force on the cleaning unit 2 is released, the cleaning unit 2 can return from the second position to the first position under the action of the first elastic part 4.

[0060] Assuming that the cleaning unit 2 cannot swing relative to the support 1 and the cleaning module 10 does not include the first elastic part 4, please refer to Figure 7 The first suction cup 30 is controlled to enter the suction state, while the second suction cup 40 is controlled to remain in the non-suction state. The second suction cup 40 is close to the window frame 200. Since one end of the cleaning unit 2 is in contact with the window frame 200, the position of the second suction cup 40 is at its closest possible distance to the window frame 200, with a distance D between the second suction cup 40 and the window frame 200. The cleaning device 100 is controlled to rotate around the axis of the first suction cup 30, allowing the second suction cup 40 to rotate and swing around the axis of the first suction cup 30. The second suction cup 40 after swinging is denoted as the second suction cup 40'. Based on the movement trajectory of the second suction cup 40... Figure 7The area marked by the cross-section line is the area not cleaned by the cleaning unit 2. That is, when the cleaning unit 2 cannot swing relative to the bracket 1 and the cleaning module 10 does not include the first elastic part 4, the cleaning device 100 has difficulty cleaning the area of ​​the glass near the window frame 200, thus affecting the cleaning effect of the cleaning device 100.

[0061] In this embodiment, since the cleaning unit 2 can swing relative to the support 1, and the cleaning module 10 also includes a first elastic component 4 for resetting the cleaning unit 2, please refer to [link to relevant documentation]. Figure 8 The system controls the first suction cup 30 to enter the adsorption state while simultaneously controlling the second suction cup 40 to remain in the non-adsorption state. The second suction cup 40 is closer to the window frame 200 than the first suction cup 30. One end of the cleaning unit 2 can abut against the window frame 200 under the action of the first elastic part 4, thereby allowing the second suction cup 40 to be as close to the window frame 200 as possible. The system controls the cleaning device 100 to rotate around the axis of the first suction cup 30, allowing the second suction cup 40 to rotate and swing around the axis of the first suction cup 30. During the rotation of the second suction cup 40, the cleaning unit 2 swings towards the side closer to the window frame 200 under the action of the first elastic part 4. In some exemplary scenarios, during the swinging process of the cleaning unit 2, the cleaning unit 2 remains in contact with the window frame 200 under the action of the first elastic part 4, ensuring that the cleaning unit 2 can clean the area of ​​the glass near the window frame 200 effectively.

[0062] In this embodiment, the cleaning unit 2 can swing relative to the bracket 1 and the cleaning module 10 also includes a first elastic component 4 for resetting the cleaning unit 2, so that the cleaning unit 2 can clean the area of ​​the glass near the window frame 200, further improving the cleaning effect of the cleaning unit 2 on the surface to be cleaned.

[0063] For some implementation methods, please refer to Figure 4 The cleaning module 10 also includes a second elastic part 5, which is disposed on the intermediate frame 3 and is used for the cleaning unit 2 to abut against the surface to be cleaned.

[0064] The elastic deformation direction of the second elastic part 5 is along the first direction, so that the cleaning unit 2 can abut against the surface to be cleaned. Please refer to [link / reference]. Figure 4 The first direction can be set to be parallel to the Z-axis direction of the cleaning module 10; or, the first direction can be set to be intersecting with the Z-axis direction of the cleaning module 10.

[0065] In some examples, the second elastic part 5 includes a spring, a damper, or an elastomer.

[0066] In this embodiment of the application, by providing the second elastic part 5, the cleaning unit 2 can be made to fit tightly against the surface to be cleaned, which helps to improve the cleaning effect of the cleaning unit 2 on the surface to be cleaned.

[0067] In some implementations, there are two or more intermediate frames 3, each intermediate frame 3 is spaced apart along the length of the cleaning unit 2, and each intermediate frame 3 is connected to the support 1. The support 1, the cleaning unit 2 and each intermediate frame 3 can form a parallelogram mechanism.

[0068] See some examples. Figure 4 Two intermediate frames 3 can be set, and the connection positions of the two intermediate frames 3 and the cleaning unit 2 are close to the corresponding ends of the cleaning unit 2. While realizing the stable support of the cleaning unit 2 on the bracket 1 through the intermediate frames 3, it also simplifies the structure of the cleaning equipment 100.

[0069] In this embodiment, a parallelogram mechanism is formed by setting up a support 1, a cleaning unit 2, and each intermediate frame 3, so that the length direction of the cleaning unit 2 can always be parallel to one direction, which is beneficial for the cleaning unit 2 to clean the surface to be cleaned.

[0070] It is worth noting that the above embodiment describes two or more intermediate frames 3 and the support 1, cleaning unit 2 and each intermediate frame 3 forming a parallelogram mechanism. In other embodiments, the number of intermediate frames 3 can also be set to one. The intermediate frame 3 is fixedly connected to the cleaning unit 2. The cleaning unit 2 is oscillatingly connected to the support 1 through the intermediate frame 3 and the oscillation direction of the cleaning unit 2 is parallel to the surface to be cleaned. With this setting, when the intermediate frame 3 oscillates, the length direction of the cleaning unit 2 is not always parallel to one direction.

[0071] For some implementation methods, please refer to Figure 4 The intermediate frame 3 includes a first intermediate frame part 31 and a second intermediate frame part 32. The first intermediate frame part 31 is connected to the support 1, and the second intermediate frame part 32 is sway-connected to the first intermediate frame part 31. The cleaning unit 2 is rotatably connected to the second intermediate frame part 32.

[0072] See some examples. Figure 4 There are two intermediate frames 3. The cleaning unit 2 is rotatably connected to the second intermediate frame 32. The support 1 and the first intermediate frame 31 are regarded as an integral structure. The integral structure formed by the support 1 and the first intermediate frame 31, the cleaning unit 2 and the two second intermediate frame 32 form a parallelogram mechanism.

[0073] In this embodiment, by setting the second intermediate frame 32 to be swayably connected to the first intermediate frame 31 and the cleaning unit 2 to be rotatably connected to the second intermediate frame 32, the second elastic part 5 can be conveniently set between the first intermediate frame 31 and the support 1.

[0074] The above embodiment describes the second intermediate frame 32 being sway-connected to the first intermediate frame 31. In other embodiments, the first intermediate frame 31 may be sway-connected to the support 1, and the cleaning unit 2 may be connected to the second intermediate frame 32.

[0075] In some examples, there may be two intermediate frames 3, with the first intermediate frame 3 and the second intermediate frame part 32 of each intermediate frame 3 fixedly connected. The two second intermediate frame parts 32 are rotatably connected to the same connecting plate, so that the bracket 1, the connecting plate and the two intermediate frames 3 form a parallelogram mechanism. At the same time, a second elastic part 5 is provided between the connecting plate and the cleaning unit 2.

[0076] In this embodiment, by setting the first intermediate frame 31 to be swayably connected to the support 1, the position of the second elastic part 5 can be set more flexibly, that is, the position of the second elastic part 5 is not limited to being set only between the first intermediate frame 31 and the support 1.

[0077] Please see Figures 9-13 , Figure 9 This is an exploded view of a cleaning device 100 provided in some embodiments of this application. Figure 10 This is a schematic diagram of the structure of the first intermediate frame 31 provided in some embodiments of this application. Figure 11 A partial enlargement of the cleaning device 100 provided in some embodiments of this application. Figure 1 , Figure 12 A partial enlargement of the cleaning device 100 provided in some embodiments of this application. Figure 2 , Figure 13 This is a partial schematic diagram of the first intermediate frame 31 provided in some embodiments of this application. The following description mainly uses the example of a second intermediate frame 32 swingably connected to the first intermediate frame 31 and a cleaning unit 2 rotatably connected to the second intermediate frame 32.

[0078] For some implementation methods, please refer to Figure 9 The intermediate frame 3 also includes a first rotating shaft 33 and a second rotating shaft 34. The axes of the first rotating shaft 33 and the second rotating shaft 34 are perpendicular to the surface to be cleaned. The first rotating shaft 33 is rotatably connected to the first intermediate frame part 31 and the second intermediate frame part 32, and the second rotating shaft 34 is rotatably connected to the second intermediate frame part 32 and the cleaning unit 2.

[0079] In some examples, the first rotating shaft 33 is fixed on the second intermediate frame 32, and both ends of the first rotating shaft 33 are rotatably connected to the first intermediate frame 31; or, the first rotating shaft 33 is fixed on the first intermediate frame 31, and the first rotating shaft 33 is rotatably connected to the second intermediate frame 32; or, the first rotating shaft 33 is rotatably connected to both the first intermediate frame 31 and the second intermediate frame 32.

[0080] See some examples. Figure 10The first intermediate frame 31 is provided with a notch 311, please refer to Figure 11 The notch 311 includes a first notch surface 312, a second notch surface 313, and a third notch surface 314. The first notch surface 312 and the second notch surface 313 are arranged opposite to each other, and the third notch surface 314 connects the first notch surface 312 and the second notch surface 313. One end of the second intermediate frame portion 32 is inserted into the notch 311, and both ends of the first rotating shaft 33 passing through the second intermediate frame portion 32 are respectively inserted into the first notch surface 312 and the second notch surface 313.

[0081] In some examples, the second rotating shaft 34 is fixed on the second intermediate frame 32, and both ends of the second rotating shaft 34 are rotatably connected to the cleaning unit 2; or, the second rotating shaft 34 is fixed on the cleaning unit 2, and the second rotating shaft 34 is rotatably connected to the second intermediate frame 32; or, the second rotating shaft 34 is rotatably connected to both the second intermediate frame 32 and the cleaning unit 2.

[0082] See some examples. Figure 9 The cleaning unit 2 includes a cleaning body 21 and a mounting frame 22. The mounting frame 22 is mounted on the cleaning body 21, and one end of the second intermediate frame 32 is rotatably connected to the mounting frame 22 via a second rotating shaft 34.

[0083] See some examples. Figure 9 The second intermediate frame 32 includes a first transverse section 321, a first longitudinal section 322, and a second transverse section 323. The first longitudinal section 322 connects the first transverse section 321 and the second transverse section 323. One end of the first transverse section 321 away from the first longitudinal section 322 is rotatably connected to the first intermediate frame 31 via a first rotating shaft 33. The second transverse section 323 is rotatably connected to the mounting frame 22 via a second rotating shaft 34.

[0084] See some examples. Figure 11 The mounting bracket 22 includes a mounting main body 221 and a mounting connecting part 222. The mounting main body 221 is connected to the cleaning body 21, and the mounting connecting part 222 is connected to the mounting main body 221. The mounting connecting part 222 is located above the second transverse section 323. The second rotating shaft 34 passes through the second transverse section 323 and its two ends are respectively inserted into the cleaning body 21 and the mounting connecting part 222. The first elastic part 4 is sleeved on the second rotating shaft 34 and is located between the second transverse section 323 and the mounting connecting part 222.

[0085] In this embodiment, by setting a first rotating shaft 33 to rotatably connect the first intermediate frame 31 and the second intermediate frame 32, and a second rotating shaft 34 to rotatably connect the second intermediate frame 32 and the cleaning unit 2, the overall structure formed by the bracket 1 and the first intermediate frame 31, the cleaning unit 2 and the two second intermediate frame 32 form a parallelogram mechanism, while the structure of the cleaning module 10 is simplified.

[0086] In some implementations, the first elastic part 4 is a torsion spring, which can be sleeved on the first rotating shaft 33, with its two ends connected to the first intermediate frame part 31 and the second intermediate frame part 32 respectively; or, please refer to Figure 11 A first elastic part 4 can be provided and sleeved on the second rotating shaft 34. The two ends of the first elastic part 4 are respectively connected to the second intermediate frame part 32 and the cleaning unit 2.

[0087] The first elastic part 4 includes a projectile body, a first connecting end, and a second connecting end. The two ends of the projectile body are respectively connected to the first connecting end and the second connecting end. When the first elastic part 4 is sleeved on the second rotating shaft 34, the first connecting end and the second connecting end are respectively inserted into the second intermediate frame 32 and the mounting frame 22.

The arc-shaped surface 3143 connects the first limiting surface 3141 and the second limiting surface 3142. One end of the second intermediate frame portion 32 is inserted into the notch 311 to match the shape of the arc-shaped surface 3143, along... Figure 10 The arc-shaped surface 3143 is located away from the direction indicated by the Y-axis, and its depth is greater than that of the first limiting surface 3141 and the second limiting surface 3142.

The third rotating shaft 35 passes through the first intermediate frame 31 and is located at one end of the two connecting ears 11. Both ends of the third rotating shaft 35 are supported on the two connecting ears 11.

[0098] In some examples, the second elastic part 5 is a spring, and the second elastic part 5 is disposed away from the third pivot 35 between the first intermediate frame part 31 and the bracket 1.

[0099] See some examples. Figure 9 The first intermediate frame 31 includes a first section 315 and a second section 316. The first section 315 is connected to one end of the second section 316. The end of the first section 315 away from the second section 316 is rotatably connected to the support 1 through a third rotating shaft 35. The second section 316 is provided with a notch 311. A second elastic part 5 is provided between the second section 316 and the support 1. From the end connected to the second section 316 to the end away from the second section 316, the first section 315 is inclined upward.

[0100] In this embodiment, a third rotating shaft 35 is provided to rotatably connect the bracket 1 and the first intermediate frame 31, and the second elastic part 5 is provided between the first intermediate frame 31 and the bracket 1, so that the cleaning unit 2 can be closely attached to the surface to be cleaned, which helps to improve the cleaning effect of the cleaning unit 2 on the surface to be cleaned.

[0101] For some implementation methods, please refer to Figure 13 The bracket 1 has a third limiting surface 12 and a fourth limiting surface 13. The first intermediate frame 31 can rotate to a position that contacts the third limiting surface 12 and to a position that contacts the fourth limiting surface 13. The third limiting surface 12 and the fourth limiting surface 13 are used to limit the range of rotation of the first intermediate frame 3.

[0102] See some examples. Figure 9 The first segment 315 includes a first segment body 3151 and a first segment connecting end 3152. The first segment connecting end 3152 is located at the end of the first segment body 3151 opposite to the second segment 316. The thickness of the first segment connecting end 3152 is less than the thickness of the first segment body 3151, and the first segment connecting end 3152 is located in the middle region of the first segment body 3151 along the thickness direction. Please refer to [link / reference]. Figure 12 The first section connector 3152 is inserted between the two connector ears 11.

[0103] See some examples. Figure 9 and Figure 12 The first section 315 also includes an abutment portion 3153, which is disposed on the connecting end 3152 of the first section; see also Figure 9 and Figure 13 A groove 14 is provided on the side of the bracket 1 opposite to the cleaning unit 2. Please refer to [link / reference]. Figure 12 The abutment portion 3153 is located in the groove 14, please refer to Figure 13 The bottom surface of the groove 14 forms a third limiting surface 12, and the first intermediate frame 31 can be rotated to the position where the abutment part 3153 contacts the third limiting surface 12.

[0104] See some examples. Figure 13 The surface of the bracket 1 located between the two connecting ears 11 forms a fourth limiting surface 13, which is connected to the third limiting surface 12, along the direction away from the cleaning unit 2 and towards the cleaning unit 2. Figure 13 In the direction indicated by the arrow on the Y-axis, the fourth limiting surface 13 is inclined downward (i.e., away from the direction indicated by the arrow on the Z-axis), and the first intermediate frame 31 can be rotated to the position where the first section connecting end 3152 contacts the fourth limiting surface 13.

[0105] In some examples, the first intermediate frame 31 rotates within a range of 10° to 30°. For example, the second intermediate frame 3 can be set to swing at an angle of 10° to 15°, 15° to 20°, 20° to 25°, or 25° to 30°, etc.

[0106] In this embodiment, by setting a third limiting surface 12 and a fourth limiting surface 13 on the bracket 1 to limit the rotation range of the first intermediate frame 3, the second elastic part 5 can make the cleaning unit 2 fit tightly against the surface to be cleaned, while also improving the stability of the cleaning module 10 structure.

[0107] In some embodiments, the cleaning module further includes a first detection component disposed on the cleaning unit or the support, the first detection component being used to detect the position of the cleaning unit relative to the support.

[0109] In some embodiments, the cleaning module further includes a second detection component disposed on the cleaning unit, the second detection component being used to detect obstacles located in front of the cleaning unit.

[0110] In some examples, there is one or more second detection components. When there are two or more second detection components, each second detection component is spaced apart along the length of the cleaning unit.

[0111] In some examples, the second detection component is a sensor or a trigger switch.

[0112] When the cleaning equipment is cleaning the glass on the window, if the second detection component comes into contact with the window frame, or if the second detection component sends the detected distance signal to the control device of the cleaning equipment, the control device can determine that the second detection component is too close to the window frame and then control the change of the movement path of the cleaning equipment.

[0113] In this embodiment, the cleaning module also includes a second detection component, so that the cleaning equipment can determine the position of obstacles such as window frames in front of it, so as to adjust the route in a timely manner.
