[0049] A window cleaning robot is a device used to clean windows. The window cleaning robot can walk on the glass and clean the glass surface. The window cleaning robot can help people solve the problem of high-rise window cleaning and outdoor window cleaning. In the prior art, window cleaning robots are generally divided into round window cleaning robots and square window cleaning robots. The round window cleaning robot has two cleaning turntables and can run flexibly on the glass surface, so it is widely used. However, due to the shape of the cleaning turntable, the round window cleaning machine is prone to cleaning blind spots when it runs to the corners. Therefore, cleaning the cleaning blind spots has become one of the important topics in the industry.

[0050] Fig.18 The figure is a schematic diagram of a circular window cleaning robot cleaning a glass surface in the related art. Due to the shape limitation of the cleaning turntable 400 itself, when it moves to the corner of the glass, a cleaning blind area 410 (shaded part in the figure) as shown in the figure will be generated, wherein the rectangular outer frame in the figure is the frame of the window.

[0051] To this end, a window cleaning machine is proposed in this embodiment, which can clean the above-mentioned blind spots.

[0052] Reference Figure 1-Figure 6 In this embodiment, a window cleaning machine is provided, including a host 100 and a cleaning device 200. Figure 1-Figure 4 In the related drawings, the upper half of the main body 100 is cut away, so that the cleaning device 200 located in the upper half of the main body 100 can be easily observed.

[0053] The cleaning device 200 is rotatably disposed on the main body 100 and is used for cleaning the surface to be cleaned.

[0054] The cleaning device 200 includes a first portion 210 and a second portion 220. The first portion 210 is rotatably disposed on the host 100, and the second portion 220 is movably disposed on the first portion 210. In this embodiment, the second portion 220 is movable relative to the first portion 210 in the radial direction of the first portion 210 of the cleaning device 200.

[0055] When the first part 210 rotates, the second part 220 rotates synchronously with the first part 210, wherein the second part 220 is used to adjust its position relative to the first part 210 according to the rotation position of the first part 210, so as to adjust the cleaning range of the cleaning device 200 accordingly, thereby increasing the cleaning range of the cleaning device 200. When the second part 220 of the cleaning device 200 rotates synchronously with the first part 210, the second part 220 can adaptively adjust its position and cover the corresponding area, thereby achieving cleaning of areas such as corners.

[0056] Set in Figure 1 The first part 210 is in the initial position, at which time the second part 220 is located inside the first part 210; Figure 1 to Figure 2 , the first part 210 rotates 30° clockwise, and the length of the second part 220 extending from the first part 210 is the first length; Figures 2 to 3 , the first part 210 rotates 15° clockwise, at which time, the first part 210 rotates 45° compared to the initial position, and the length of the second part 220 extending from the first part 210 is the second length; Figure 3 to Figure 4 , the first part 210 rotates 45° clockwise, at which time, the first part 210 rotates 90° compared to the initial position, and the second part 220 retracts into the second part 220. The second length is greater than the first length.

[0057] according to Figure 1-Figure 4 From the relative positions of the first portion and the second portion 220, it can be seen that the second portion 220 rotates synchronously with the first portion 210, and when the first portion 210 is at different positions, the relative positions of the second portion 220 and the first portion 210 are different.

[0058] In this embodiment, the second part 220 moves along a preset path. When the second part 220 rotates following the first part 210 , the second part 220 moves along the preset path synchronously to adjust the cleaning range of the cleaning device 200 accordingly.

[0059] In some embodiments, the second part may extend from the first part by rotating, folding, etc.

[0060] Reference Figure 4 and Figure 5 As shown, when the first part 210 is rotated to the first type position, the second part 220 is located in the first part 210, and the cleaning device 200 has a first cleaning range; Figure 4 and Figure 6 As shown, when the first part 210 rotates to the second position, the second part 220 extends out of the first part 210, and the cleaning device 200 has a second cleaning range, which is larger than the first cleaning range.

[0061] The first type of positions and the second type of positions are alternately arranged so that the first cleaning range and the second cleaning range of the cleaning device 200 together enclose a total cleaning range 300, and the total cleaning range 300 is in the shape of a parallelogram, a rectangle, a quasi-rectangle, a square, or a quasi-square.

[0062] Reference Figure 7-Figure 11 The total cleaning range 300 is a parallelogram, a rectangle, a quasi-rectangle, a square, and a quasi-square. A quasi-rectangle means that at least one or more of the four corners of the rectangle are rounded, and a quasi-square means that at least one of the four corners of the square are rounded. Fig. 9 and Fig.11 In the embodiment, the four corners are all provided with rounded corners, and the edges are all in a straight line shape. In other embodiments, the edges can also be in an arc shape.

[0063] The window cleaning machine further comprises a guide control member, which is used to control and guide the movement of the second part 220 during the synchronous rotation of the second part 220 , so as to correspondingly adjust the position of the second part 220 relative to the first part 210 , so as to correspondingly adjust the cleaning range of the cleaning device 200 .

[0064] Reference Fig.12 In this embodiment, the guide control member includes a guide rail 230, which is disposed on the host 100. The guide rail 230 includes a first structure corresponding to the first type of position and a second structure corresponding to the second type of position. In this embodiment, the guide rail 230 is a closed structure connected end to end.

[0065] When the cleaning device 200 rotates, the second portion 220 rotates and simultaneously moves along the guide track 230 between the first position and the second position to increase the cleaning range of the cleaning device 200 .

[0066] The distance of the first type of position relative to the center of the cleaning device 200 is not greater than the distance of the second type of position relative to the center of the cleaning device 200 .

[0067] like Fig.12As shown, in this embodiment, the guide track 230 is quasi-square, with four rounded corners and four sides that are concave arcs (i.e., the convex direction of the arcs faces the center). The four sides of the guide track 230 are the first structure corresponding to the first type of position, and the four corners are the second structure corresponding to the second type of position.

[0068] The first part 210 rotates together with the second part 220 , so that the cleaning device 200 has a cleaning mode in a first direction. At this time, the first part 210 and the second part 220 move in a clockwise or counterclockwise direction, thereby cleaning the surface to be cleaned.

[0069] The second part 220 moves relative to the first part 210, so that the cleaning device 200 has a cleaning mode in the second direction. At this time, the second part 220 performs a linear telescopic motion relative to the first part 210, thereby cleaning the surface to be cleaned.

[0070] In this embodiment, the cleaning method in the first direction is interlaced with the cleaning method in the second direction to improve the cleaning effect of the cleaning device 200. When the cleaning device 200 is working, the first part 210 and the second part 220 rotate synchronously, and at the same time, the second part 220 performs a linear telescopic motion relative to the first part 210, so that the cleaning device 200 has a larger cleaning area and improves the cleaning effect.

[0071] Reference Figure 4 The window cleaning machine has a horizontal axis in a first preset direction and a vertical axis in a second preset direction, and the first type of position is located in a quadrant surrounded by the horizontal axis and the vertical axis. Figure 4 In the figure, the horizontal axis is the x-axis and the vertical axis is the y-axis. When the window cleaning machine identifies a frame corner, one of the second positions faces the frame corner, and the cleaning device 200 rotates so that the second part 220 moves to the second position and extends into the frame corner for cleaning. Figure 4 In , P1 represents the first type of position and P2 represents the second type of position.

[0072] Reference Fig.13 , taking the window cleaning machine wiping the upper left corner area as an example, the window cleaning machine moves to position a3 via position a1 and position a2 in sequence. During this process, the window cleaning machine determines that the machine is close to the upper frame of the window based on identification devices such as gyroscopes, current or micro switches, wherein the window cleaning machine moves to the left and finally reaches the left frame. When reaching the left frame, the window cleaning machine adjusts its posture based on the gyroscope or other sensing devices so that the central axis of the window cleaning machine is perpendicular to the horizontal plane (i.e., the posture of position a3). Subsequently, the first part 210 rotates, and at this time, the second part 220 rotates synchronously with the first part 210, and adjusts the telescopic state according to the guide track 230, thereby completing the wiping. Fig.13 The outer frame of the middle rectangle represents the border of the window.

[0073] It should be noted that the window cleaning machine at position a3 is partially cut away to facilitate observation of the cleaning device 200 near the corner of the frame.

[0074] In this embodiment, the first part 210 is a cleaning plate, and the second part 220 is a telescopic cleaning rod, and the outer end of the telescopic cleaning rod has a cleaning function. Specifically, the outer end of the telescopic cleaning rod can be provided with a cleaning member 222 such as a wiping cloth.

[0075] The telescopic cleaning rod is connected to the guide rail 230. When the telescopic cleaning rod rotates with the cleaning disc, the telescopic cleaning rod moves along the guide rail 230 to extend out of the cleaning disc for cleaning or to be located in the cleaning disc.

[0076] like Fig.14 and Fig.15 As shown, the fixing plate 240 of the cleaning device 200 is used to be fixed on the main unit 100, wherein the guide rail 230 is arranged on the fixing plate 240. The first part 210 is rotatably connected to the main unit 100, and the first part 210 is provided with a sliding groove 211 arranged in a radial direction, and the second part 220 is slidably arranged in the sliding groove 211. A spring 223 is provided at the inner end of the second part 220, and the spring 223 is used to provide an elastic force to the second part 220, and the direction of the elastic force is parallel to the sliding groove. A roller 224 is provided on the rod body 221 of the second part 220, and under the action of the elastic force applied by the spring 223 to the second part 220, the roller 224 always keeps in contact with the inner side surface of the guide rail 230. Fig.14 In the figure, only the cleaning device 200 on the left side is subjected to the explosion treatment.

[0077] A mounting cover 212 is mounted on the first portion 210 , and the mounting cover 212 and the first portion 210 may be connected by screws.

[0078] like Figure 5 As shown, the mounting cover 212 is provided with a guide groove 2121, wherein the rod body 221 of the second part 220 is slidably connected to the guide groove 2121, and the spring 223 is in contact with one end of the guide groove 2121. The guide groove 2121 is provided with an opening near one end of the cleaning member 222 on the second part 220, and the rod body 221 is slidably inserted into the opening, wherein two bosses 2211 are symmetrically provided on the rod body 221, the two bosses 2211 are located on the same straight line, and the maximum distance between the two is greater than the width of the opening. In the figure, the width direction of the opening is parallel to the horizontal direction. The boss 2211 is used to limit the sliding range of the second part 220 on the first part 210, so that the rod body 221 will not slide out of the guide groove 2121 as a whole under the action of the spring 223.

[0079] Reference Figure 1-Figure 5When the first part 210 rotates, the second part 220 rotates synchronously with the first part 210 under the constraints of the sliding groove 211 and the guide groove 2121; under the action of the guide rail 230 and the spring 223, the roller 224 always rolls along the guide rail 230. In this process, based on the shape of the guide rail 230, the second part 220 makes a linear motion relative to the first part 210: extending out of the first part 210 or retracting the first part 210. In this way, under the mutual cooperation of the first part 210 and the second part 220, the first cleaning range and the second cleaning range are obtained, so that the cleaning device 200 has a larger cleaning area and improves the cleaning effect.

[0080] During the rotation of the first part 210, the second part 220 has no effect on the window frame, so the second part 220 has no interference with the glass frame during rotation, avoiding the window cleaning machine falling due to the second part 220 colliding with the window frame, thereby reducing the risk of the window cleaning machine falling. The second part 220 runs according to the shape of the preset guide track 230, and rotates and slides without resistance in cooperation with the sliding groove 211, the spring 223 and the guide track 230, thereby achieving cleaning of the corner area of ​​the window.

[0081] In addition to using the guide rail 230 to drive the second part 220 to move linearly relative to the first part 210, the second part 220 can also be driven by a driving device such as a linear motor or a cylinder, wherein the driving device is controlled by a controller. When the first part 210 rotates, the second part 220 rotates synchronously with the first part 210. At the same time, the controller generates a corresponding control signal to the driving device to control the second part 220, so that the second part 220 adjusts its position relative to the first part 210 according to the rotation position of the first part 210.

[0082] Reference Figure 1-Figure 4 In this embodiment, only one second part 220 is provided on the cleaning device 200. In other embodiments, multiple second parts 220, for example, four second parts 220, can be provided as needed. For example, when the first part 210 rotates 90°, the four second parts 220 can cooperate synchronously to achieve cleaning of a circle.

[0083] In this embodiment, the guide rail 230 is quasi-square, with four rounded corners and four sides that are all concave arcs. Since the four sides are all concave arcs, it can be ensured that the second part 220 will not hit the frame of the window during the rotation process.

[0084] In addition, in other embodiments, the four sides can be set to be straight lines or convex arcs (i.e., the convex direction of the arc is away from the center). For example, the guide track 230 is a straight edge because the second part 220 is softly connected to the frame, so the second part 220 will have soft contact with the frame.

[0085] The shape of the guide rail 230 can also be set as needed.

[0086] like Fig.16 As shown, in one embodiment, the guide track 230 includes an outer convex arc 231 and a rounded corner 232, the outer convex arc 231 corresponds to the first type of position, and the rounded corner 232 corresponds to the second type of position. When the motor drives the first part 210 to rotate, the second part 220 rotates synchronously therewith. When the second part 220 moves to the rounded corner position, the rounded corner will produce a certain resistance to the rotation of the second part 220. At this time, the motor needs to output a large power to make the second part 220 leave the rounded corner. Since there is only one rounded corner and the other positions are all outer convex arcs, the rotation of the second part 220 will be smoother, and the motor output shaft will be subject to less resistance.

[0087] The amount of rounding can be set as needed, for example Fig.17 As shown, in another embodiment, the guide track 230 includes an outer convex arc 231 and two rounded corners 232 .

[0088] Reference Fig.13 When the window cleaning machine is in position a3, the window cleaning machine is in a vertical state as a whole. At this time, the vertical symmetry axes of the guide rail 230 and the window cleaning machine are basically coincident, thereby ensuring that when the second part 220 moves to an angle facing the frame, the second part 220 extends the longest relative to the first part 210, thereby cleaning the innermost position of the corner area. If there is a large deviation between the vertical symmetry axes of the guide rail 230 and the window cleaning machine, the second part 220 will touch the frame during the rotation of the first part 210, that is, when the second part 220 extends the longest relative to the first part 210, the second part 220 faces the frame instead of the corner area, thereby causing the corner area to be missed.
