[0024] In the following embodiments, when the two components are coupled, it can be considered as direct coupling or indirect coupling. One embodiment of the present invention provides a window cleaning machine with a lifting cleaning component. Figure 1 This is a schematic diagram of a window cleaning machine according to an embodiment of the present invention. Figure 2 yes Figure 1 The diagram shown is a bottom view of the window cleaning machine. Figure 3 Yes, yes Figure 1 The diagram shows the operation of a window cleaning machine. Figure 4 yes Figure 1 The diagram shown is an exploded view of the window cleaning machine.

[0025] like Figures 1 to 4 As shown, the window cleaning machine 1 includes a main body 11, which has a top shell 31 and a bottom shell 33, which define the internal space of the main body 11.

[0026] like Figure 2As shown, the bottom shell 33 of the main body 11 includes multiple air inlets 21. In this embodiment, at least two drive mechanisms 23 are arranged in parallel opposite directions, and the multiple air inlets 21 are located between the at least two drive mechanisms 23. In this embodiment, the drive mechanism 23 includes a tracked drive mechanism. The bottom shell 33 is coupled to a floating plate 25, which includes a first opening 27 corresponding to the multiple air inlets 21 and a clearance opening 29 corresponding to the drive mechanism 23. The first opening 27 is configured to avoid the multiple air inlets 21, and the clearance opening 29 is configured to avoid the drive mechanism 23. The window cleaning machine 1 also includes a cleaning component 22 and a cleaning assembly 24. In this embodiment, the cleaning component 22 includes a sheet-like fabric. The cleaning component 22 is detachably fixed to the floating plate 25, which is coupled to the bottom shell 32 and located between the at least two cleaning assemblies 24. The cleaning assembly 24 includes a scraper 241, and the at least two cleaning assemblies 24 are arranged in parallel opposite directions and perpendicular to the at least two drive mechanisms 23.

[0027] like Figure 3 As shown, when the window cleaning machine 1 performs cleaning work, the cleaning component 22 and the scraper 241 are configured to remove particles on the panel 28 that come into contact with the cleaning component 22 and the scraper 241 in the moving path of the window cleaning machine 1.

[0028] In this embodiment, the plate surface 41 comprises the surface of a glass plate, and the particles include dust particles. In one embodiment, the particles include water particles. In another embodiment, the particles include oil particles.

[0029] like Figure 4 As shown, the fan 35 is located in the internal space and corresponds to a plurality of air inlets 21 on the bottom shell 33. The fan 35 is configured to draw air through the plurality of air inlets 21 to generate negative pressure and to form a vacuum zone between at least two drive mechanisms 23, so that the window cleaning machine 1 adheres to the surface. Figure 3 On the panel 28 shown. In this embodiment, the window cleaning machine 1 includes at least two lifting mechanisms 37 located in the interior space. Each of the at least two lifting mechanisms 37 is coupled to a cleaning component 24. The lifting mechanisms 37 are configured to lift the cleaning component 24.

[0030] like Figure 5 As shown, the lifting mechanism 37 includes a rotating column 371, the outer wall of which has an inclined groove 373, a drive shaft 375 passing through the base 372 and one end of the drive shaft 375 being coupled to the rotating column 371, and the other end of the drive shaft 375 being coupled to a motor 377. The drive shaft 375 is configured to transmit the power of the motor 377 to the rotating column 371 to drive the rotating column 371.

[0031] In this embodiment, the rotating column 371 has a top positioning magnet 374 and a bottom positioning magnet 376 of the groove 373. A Hall effect sensor 379 is located on the base 372. The Hall effect sensor 379 is configured to sense the positioning magnet to control the power output of the motor 377 to raise and lower the cleaning assembly 24.

[0032] like Figure 6 As shown, the cleaning component 24 includes a connecting rod 243. One end of the connecting rod 243 is coupled to the inclined slide 373 of the lifting mechanism 37, and the other end of the connecting rod 243 is coupled to the clamping member 245, as shown. Figure 6 As shown, the clamping member 245 has a locking groove 247, which is configured to secure the scraper 241 within it. In this embodiment, the scraper 241 includes a support member 249, which axially passes through the scraper 241. In this embodiment, the cleaning assembly 24 also includes two springs 39, which abut against the bottom shell 33 and the cleaning assembly 24, respectively. The springs 39 are configured to evenly abut against the plate surface 28 when the cleaning assembly 24 is lowered.

[0033] In this embodiment, as Figures 5-7 As shown, the power of the motor 377 is transmitted to the rotating column 371 through the transmission shaft 375 to drive the rotating column 371 to rotate. Since the connecting rod 243 of the cleaning component 24 is coupled to the inclined slide 373 of the lifting mechanism 37, when the rotating column 371 rotates, the connecting rod 243 of the cleaning component 24 slides in the inclined slide 373 along with the rotation of the rotating column 371 to the top or bottom of the inclined slide 373 to lift the cleaning component 24.

[0034] For example, when the connecting rod 243 of the cleaning assembly 24 slides to the top of the inclined slide 373, the top positioning magnet 374 of the rotating column 371 is also moved to a position that can be sensed by the Hall effect sensor 379. The Hall effect sensor 379 generates a control signal to the microcontroller in response to the change in magnetic field to stop the motor 377 from continuing to output power. At this time, the cleaning assembly 24 is raised without contacting the plate surface.

[0035] When the connecting rod 243 of the cleaning assembly 24 slides to the bottom of the inclined slide 373, the bottom positioning magnet 376 of the rotating column 371 is also moved to a position that can be sensed by the Hall effect sensor 379. The Hall effect sensor 379 responds to the change in magnetic field and generates a control signal to the microcontroller to stop the motor 377 from continuing to output power. At this time, the cleaning assembly 24 is lowered and comes into contact with the plate surface 28.

[0036] One embodiment of this utility model provides a lifting control system for the cleaning component 41 of a window cleaning machine. Figure 8This is a block diagram of the lifting control system 8 of the cleaning component 41 of a window cleaning machine according to an embodiment of the present invention. In this embodiment, the system includes multiple sensors 43, which are configured to sense foreign objects or the edge of a panel and generate sensing signals. A microcontroller 45 is configured to generate drive signals and lifting control signals in response to the sensing signals. At least two drive mechanisms 47 are included. In this embodiment, the drive mechanisms 47 include tracked drive mechanisms. The drive mechanisms 47 are configured to move the window cleaning machine away from the foreign object or the edge in response to the drive signals. In this embodiment, the at least two drive mechanisms 47 are arranged in parallel and opposite directions.

[0037] At least two lifting mechanisms 49 are each coupled to a cleaning component 41. The lifting mechanisms 49 are configured to raise the cleaning component 41 located on the leading side and lower the cleaning component 41 located on the trailing side in response to the lifting control signal to remove particles on the movement path of the window cleaning machine. The at least two cleaning components 41 are arranged in parallel opposite directions and perpendicular to the at least two drive mechanisms 47.

[0038] Figure 9A This is a schematic diagram of the lifting control of the cleaning components of a window cleaning machine according to an embodiment of this utility model. Figure 9B yes Figure 9A The diagram shows a cross-sectional view of the lifting control mechanism of the window cleaning machine. Figures 9A-9B As shown, for example, when the sensor of the window cleaning machine senses a foreign object 53 (e.g., a window frame) on the panel 51, in this embodiment, when the window cleaning machine collides with the foreign object 53, the sensor generates a sensing signal, the microcontroller responds to the sensing signal to generate a drive signal and a lifting control signal, at least two drive mechanisms respond to the drive signal to make the window cleaning machine move away from the foreign object 53, and the lifting mechanism responds to the lifting control signal to raise the cleaning component 52 located on the leading side 55 and lower the cleaning component 54 located on the rear side 57 to remove particles on the movement path of the window cleaning machine.

[0039] Figure 10A This is a schematic diagram of the lifting control of the cleaning components of a window cleaning machine according to an embodiment of this utility model. Figure 10B yes Figure 10A The diagram shows a cross-sectional view of the lifting control mechanism of the window cleaning machine. Figures 10A-10BAs shown, when the sensor of the window cleaning machine senses the edge 63 of the panel 61, in this embodiment, when the sensor of the window cleaning machine senses that the body of the window cleaning machine extends beyond the edge 63 of the panel 61, the sensor generates a sensing signal. The microcontroller responds to the sensing signal to generate a drive signal and a lifting control signal. At least two drive mechanisms respond to the drive signal to move the window cleaning machine away from the edge 63. The lifting mechanism responds to the lifting control signal to raise the cleaning component 62 located on the leading side 65 and lower the cleaning component 64 located on the rearward side 67 to remove particles on the movement path of the window cleaning machine.

[0040] In summary, one embodiment of this utility model provides a method for controlling the lifting and lowering of a cleaning component in a window cleaning machine. For example... Figure 11 As shown, in step S901, when the sensor of the window cleaning machine senses that the window cleaning machine has collided with a foreign object on the board surface or when the sensor of the window cleaning machine senses that the body of the window cleaning machine exceeds the board surface, a sensing signal is generated. In step S903, the microcontroller responds to the sensing signal to generate a drive signal and a lifting control signal.

[0041] In step S905, at least two drive mechanisms respond to the drive signal to move the window cleaning machine away from the foreign object or the edge. In step S907, the lifting mechanism responds to the lifting control signal to raise the cleaning component located on the leading side and lower the cleaning component located on the rearward side. The cleaning component on the rearward side abuts against the plate surface to remove particles from the movement path of the window cleaning machine.
