Description

Technical Field

[0001] The utility model relates to the technical field of window-cleaning robots, in particular to a rotary disc sealing structure of the window-cleaning robot. Background Art

[0002] A window cleaning robot is an automated device used to clean windows. It can operate autonomously or remotely. It adheres to the surface of the window and uses mechanisms such as a robotic arm or a rotating disk, along with detergent or water, to wipe and clean the window.

[0003] In the existing technology, window cleaning robots generally use a single suction seal structure. In this single suction seal design, if the seal leaks, the robot can easily lose its suction force and fall. In addition, when cleaning edgeless glass surfaces, in order to reach the edge, the cleaning disc often needs to be close to or even beyond the edge. However, if it uses a single suction seal structure, when an edge is detected, the robot will usually control itself to retreat or stop working to prevent leakage and falling, making it difficult to effectively clean the edge. Therefore, the existing technology has defects and needs improvement. Utility Model Content

[0004] In order to solve one or more problems in the prior art, the present utility model provides a turntable sealing structure of a window cleaning robot.

[0005] The technical solution of the present utility model is as follows: A turntable sealing structure of a window cleaning robot, comprising: a main body, a turntable component and a negative pressure part, the turntable component is connected to the main body, the negative pressure part is arranged on the main body, and at least two groups of sealing parts are arranged on the turntable component, the negative pressure part is used to vacuum the sealing parts so that the sealing parts form negative pressure and are adsorbed on the working plane, and the at least two groups of sealing parts are used to maintain the adsorption state of the other group of sealing parts when the negative pressure in one group of sealing parts disappears.

[0006] Using the above technical solution, in the turntable sealing structure of the window cleaning robot, when the number of the sealing parts is two groups, and the sealing parts include a first sealing structure and a second sealing structure, the first sealing structure is arranged on the turntable part, and the second sealing structure is arranged on the outer peripheral side of the first sealing structure.

[0007] According to the above technical solutions, in the rotary disk sealing structure of the window cleaning robot, an air passage is provided between the first sealing structure and the second sealing structure, the negative pressure part is connected to the air passage, and the negative pressure part vacuums the first sealing structure and the second sealing structure through the air passage to form a negative pressure; or

[0008] The first sealing structure is connected to the negative pressure part, and an air channel is provided between the first sealing structure and the second sealing structure. The negative pressure part forms negative pressure by vacuuming the first sealing structure, and the first sealing structure then transfers the negative pressure to the second sealing structure through the air channel.

[0009] By adopting the above-mentioned technical solutions, in the turntable sealing structure of the window cleaning robot, the negative pressure part includes a vacuum pump for evacuating the sealing part so that the sealing part forms a negative pressure and is adsorbed on the working plane.

[0010] By adopting the above-mentioned technical solutions, the turntable sealing structure of the window cleaning robot further includes a detection part, which is arranged on one side of the turntable and is used to detect the edge of the working plane.

[0012] By adopting the above-mentioned technical solutions, in the turntable sealing structure of the window cleaning robot, when there are two groups of turntable components, the detection part is arranged between the two groups of turntable components.

[0013] By adopting the above-mentioned technical solutions, in the turntable sealing structure of the window cleaning robot, the detection part includes a detection rod.

[0014] By adopting the above-mentioned technical solutions, in the turntable sealing structure of the window cleaning robot, the number of the detection rods is the same as the number of the turntable parts, which are used to detect whether the corresponding turntable parts have reached the edge of the working plane.

[0015] In the present invention, by providing at least two sets of sealing parts, when the negative pressure disappears in one set of sealing parts, the other set of sealing parts can still maintain the adsorption state for a period of time, thereby preventing the robot from falling quickly. This redundant design greatly improves the safety of the robot. The use of multiple sets of sealing parts ensures that the robot can maintain a stable adsorption force during the cleaning process, and can maintain the stability of the robot even when encountering external interference such as wind and vibration. Due to the presence of multiple sets of sealing parts, the robot can still maintain effective adsorption force when approaching or exceeding the edge position, thereby being able to more effectively clean the edge area, solving the problem of difficult edge cleaning in the prior art. The layout of multiple sets of sealing parts improves the fault tolerance of the robot. Through the design of multiple sets of sealing parts, the robot can adapt to different types of window surfaces, including flat glass and curved glass, which improves the scope of application of the robot.

[0020] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections, direct connections, or indirect connections through an intermediate medium; they may refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0023] In the present utility model, it should also be noted that the directional terms such as one side, one end, the other end, top and bottom in the embodiments of the present application are merely relative concepts or are based on the normal use status of the product, and should not be considered as restrictive.

[0024] like Figure 1 and Figure 2As shown, an embodiment of the present application provides a turntable sealing structure for a window-cleaning robot, comprising a main body 1, a turntable 2, and a negative pressure unit 3. The turntable 2 is connected to the main body 1, and the negative pressure unit 3 is disposed on the main body 1. The turntable 2 is provided with at least two sets of sealing portions 4. The negative pressure units 3 are used to apply vacuum to the sealing portions 4, creating a negative pressure and adsorbing the sealing portions 4 against the working surface. The at least two sets of sealing portions 4 are configured so that when the negative pressure in one set of sealing portions 4 disappears, the other set of sealing portions 4 maintains the adsorption state. In this embodiment, the main body 1 is the core component of the window-cleaning robot, supporting the turntable 2 and the negative pressure unit 3 and providing the robot's overall structure and stability. The turntable 2 is connected to the main body 1 and is used to hold a cleaning cloth or brush for contact with the window surface during cleaning. The turntable 2 is designed to rotate on the main body 1 to better cover the window surface. The negative pressure unit 3 is disposed on the main body 1 and is used to apply vacuum to the sealing portions 4. When the negative pressure unit 3 is in operation, it draws air out of the sealing portions 4, creating a negative pressure. This negative pressure allows the sealing parts 4 to adhere tightly to the work surface, ensuring the robot does not fall during the cleaning process. The sealing parts 4 are mounted on the turntable 2 and comprise at least two sets. Each set of sealing parts 4 is capable of generating suction under the action of negative pressure. When the negative pressure in one set of sealing parts 4 disappears, the other set of sealing parts 4 can maintain suction for a period of time. This design improves the robot's safety. The presence of at least two sets of sealing parts 4 ensures greater fault tolerance and reliability during the cleaning process. If one set of sealing parts 4 requires a brief period of relief from negative pressure, the other set can immediately take over, ensuring the robot's stability and safety. The negative pressure unit 3 evacuates the sealing parts 4, creating negative pressure and adhering them to the work surface. This suction method ensures that the robot does not fall due to external factors (such as wind or vibration) during the cleaning process. If the window cleaning robot encounters an edge or obstacle during cleaning, the suction force of the sealing parts 4 can be adjusted to ensure smooth passage or to stop operation, preventing accidents.

[0025] Specifically, by providing at least two groups of sealing parts 4, when the negative pressure disappears in one group of sealing parts 4, the other group of sealing parts 4 can still maintain the adsorption state for a period of time, thereby preventing the robot from falling quickly. This redundant design greatly improves the safety of the robot. The use of multiple groups of sealing parts 4 ensures that the robot can maintain a stable adsorption force during the cleaning process, and can maintain the stability of the robot even when encountering external interference such as wind and vibration. Due to the presence of multiple groups of sealing parts 4, the robot can still maintain effective adsorption force when approaching or exceeding the edge position, so that the edge area can be cleaned more effectively, solving the problem of difficult edge cleaning in the prior art. The layout of multiple groups of sealing parts 4 improves the fault tolerance of the robot. Through the design of multiple groups of sealing parts 4, the robot can adapt to different types of window surfaces, including flat glass and curved glass, which improves the scope of application of the robot.

[0026] like Figure 3 As shown, preferably, when the sealing portion 4 comprises two groups and includes a first sealing structure 40 and a second sealing structure 41, the first sealing structure 40 is disposed on the turntable 2, and the second sealing structure 41 is disposed on the outer periphery of the first sealing structure 40. In this embodiment, the first sealing structure 40 is disposed on the turntable 2 and connected to the main body 1. It is used to generate negative pressure adsorption under the action of the negative pressure portion 3, ensuring that the robot can be stably adsorbed on the working surface. The second sealing structure 41 is disposed on the outer periphery of the first sealing structure 40, forming an additional sealing layer. When the negative pressure in the first sealing structure 40 disappears, the second sealing structure 41 maintains the adsorption state, preventing the robot from falling. By dividing the sealing portion 4 into the first sealing structure 40 and the second sealing structure 41, a multi-layer sealing design is achieved. This design improves the safety of the robot because even if one sealing structure fails, the other sealing structure can still maintain adsorption. If the first sealing structure 40 leaks, the second sealing structure 41 can continue to maintain adsorption, ensuring that the robot will not fall due to the failure of a single sealing structure. The multi-layer sealing design improves the robot's stability during the cleaning process, maintaining stable suction even when encountering external interference. Due to the presence of the second sealing structure 41, the robot can maintain effective suction even when approaching or exceeding the edge position, thereby more effectively cleaning the edge area.

[0027] Preferably, when three groups of sealing parts 4 are provided on the turntable 2, the three groups of sealing parts 4 can be evenly distributed on the turntable 2 to form a three-layer protection, or arranged at other angles as needed. Such a layout can ensure that at least one group of sealing parts 4 always remains in contact with the working plane, even when the turntable 2 rotates. The negative pressure part 3 is connected to each group of sealing parts 4 through an airway or gap to provide a uniform negative pressure. In this way, even if one group of sealing parts 4 leaks, the other two groups of sealing parts 4 can still maintain sufficient adsorption force to ensure that the robot does not fall.

[0028] like Figure 2 and Figure 3 As shown, in one feasible embodiment, an air channel (not shown) is provided between the first sealing structure 40 and the second sealing structure 41, and the negative pressure part 3 is connected to the air channel, and the negative pressure part 3 vacuums the first sealing structure 40 and the second sealing structure 41 through the air channel to form a negative pressure; or,

[0029] The first sealing structure 40 is connected to the negative pressure part 3, and an airway (not shown) is provided between the first sealing structure 40 and the second sealing structure 41. The negative pressure part 3 forms a negative pressure by vacuuming the first sealing structure 40, and the first sealing structure 40 then transfers the negative pressure to the second sealing structure 41 through the airway.

[0030] As described above, in Example 1, when the negative pressure unit 3 is used to vacuum the first sealing structure 40 and the second sealing structure 41 through the air channel to form a negative pressure, the negative pressure unit 3 is directly connected to the air channel, and the first sealing structure 40 and the second sealing structure 41 are vacuumed simultaneously through the air channel. In this way, both sealing structures can form negative pressure adsorption, ensuring that the robot is stably adsorbed on the working surface. This design improves the overall sealing effect because both sealing structures can independently form negative pressure adsorption. Even if one of the sealing structures leaks, the other sealing structure can still maintain the adsorption state, thereby preventing the robot from falling. In addition, this design also improves the stability of the robot during the cleaning process, and can maintain stable adsorption of the robot even when encountering external interference. In Example 2, when the negative pressure unit 3 is used to vacuum the first sealing structure 40 to form a negative pressure, and the first sealing structure 40 then transfers the negative pressure to the second sealing structure 41 through the air channel, the negative pressure unit 3 first vacuums the first sealing structure 40 to form negative pressure adsorption. The first sealing structure 40 then transmits negative pressure to the second sealing structure 41 through the airway, enabling the second sealing structure 41 to also generate negative pressure. This design also improves the overall sealing effect, as both sealing structures can generate negative pressure. It is worth noting that the second sealing structure 41 is located on the outer periphery of the first sealing structure 40. This means that when the robot moves to the edge or corner of the window, the second sealing structure 41 may first contact the edge and potentially lose negative pressure. The first sealing structure 40 is the primary negative pressure source, providing the primary suction force most of the time. Even if the second sealing structure 41 loses negative pressure due to contact with the edge, the first sealing structure 40 can still maintain sufficient suction to prevent the robot from falling. The airway uses very small pores or gaps, which helps reduce the possibility of air leakage. Small pores or gaps restrict air flow, thereby maintaining a more stable negative pressure within the sealing structure. This design improves the efficiency of the entire sealing system, ensuring that the first sealing structure 40 can maintain sufficient suction even if the second sealing structure 41 loses negative pressure.

[0031] like Figure 2As shown, further, the negative pressure part 3 includes a vacuum pump, which is used to evacuate the sealing part 4 so that the sealing part 4 forms a negative pressure adsorption on the working plane. The negative pressure part 3 includes a vacuum pump, which is the core component of the entire sealing system. The function of the vacuum pump is to evacuate the sealing part 4, thereby forming a negative pressure between the sealing part 4 and the working plane. When the vacuum pump is started, it will extract the air in the sealing part 4 and reduce the air pressure in the sealing part 4. Due to the effect of the external atmospheric pressure, the sealing part 4 will be pressed against the working plane, forming negative pressure adsorption. Through the vacuuming action of the vacuum pump, the sealing part 4 can be firmly adsorbed on the working plane. This negative pressure adsorption mechanism ensures that the robot will not fall due to external interference during the cleaning process.

[0032] like Figure 2 As shown, it further includes a detection unit 5, which is arranged on one side of the turntable 2 and is used to detect the edge of the working plane. The detection unit 5 is a sensor or detector on the window cleaning robot, which is arranged on one side of the turntable 2 and is used to detect the edge of the working plane. The detection unit 5 uses sensor technology (such as infrared, ultrasonic, optical sensor, etc.) to identify the edge of the working plane. When the robot approaches the edge, the detection unit 5 can sense it and send a signal. The detection unit 5 transmits the detected edge information to the robot's control system. The control system adjusts the robot's movement path and cleaning strategy based on this information. Through edge detection, the robot can plan the best cleaning path to avoid exceeding the range of the working plane, thereby improving cleaning efficiency.

[0033] like Figure 3 As shown, further, the number of turntables 2 is at least one group. When there are two groups of turntables 2, the detection unit 5 is located between the two groups of turntables 2. The number of turntables 2 is at least one group, which means that the window cleaning robot can have one or more turntables 2. When there are two groups of turntables 2, they may be designed to operate relatively independently to improve cleaning efficiency and coverage. When there are two groups of turntables 2, the detection unit 5 is located between the two groups of turntables 2. This layout allows the detection unit 5 to simultaneously monitor the operating status of both groups of turntables 2 and their relationship to the edge of the work plane. The detection unit 5 uses sensor technology to detect the edge of the work plane. Because the detection unit 5 is located between the two groups of turntables 2, it can provide more comprehensive edge detection, ensuring that neither group of turntables 2 exceeds the edge of the work plane. The information provided by the detection unit 5 is used for the robot's path planning. When an edge is detected, the robot can adjust its movement path to ensure that both groups of turntables 2 effectively clean the work plane while avoiding exceeding the edge.

[0034] like Figure 3As shown, further, the detection part 5 includes detection rods, and the number of the detection rods is the same as the number of the turntable parts 2, which are used to detect whether the corresponding turntable parts 2 have reached the edge of the working plane. The detection part 5 includes one or more detection rods, and each detection rod corresponds to a turntable part 2. The detection rod is a sensor for physically contacting or sensing the edge of the working plane. The number of detection rods is the same as the number of turntable parts 2, which means that each turntable part 2 has a corresponding detection rod to monitor its position. Each detection rod is responsible for detecting whether its corresponding turntable part 2 is close to the edge of the working plane. When the detection rod touches the edge, it triggers a signal. The signals detected by the detection rod are transmitted to the control system of the robot, and the control system adjusts the movement path and cleaning strategy of the robot according to these signals. Through the edge detection of the detection rod, the robot can accurately plan its movement path to ensure that the turntable part 2 does not exceed the edge of the working plane by too much distance.

[0035] By adopting the above-mentioned technical solutions, the utility model sets at least two groups of sealing parts 4. When the negative pressure disappears in one group of sealing parts 4, the other group of sealing parts 4 can still maintain the adsorption state for a period of time, thereby preventing the robot from falling quickly. This redundant design greatly improves the safety of the robot. The use of multiple groups of sealing parts 4 ensures that the robot can maintain a stable adsorption force during the cleaning process, and can maintain the stability of the robot even when encountering external interference such as wind and vibration. Due to the presence of multiple groups of sealing parts 4, the robot can still maintain effective adsorption force when approaching or exceeding the edge position, so that the edge area can be cleaned more effectively, solving the problem of difficult edge cleaning in the prior art. The layout of multiple groups of sealing parts 4 improves the fault tolerance of the robot. Through the design of multiple groups of sealing parts 4, the robot can adapt to different types of window surfaces, including flat glass and curved glass, which improves the scope of application of the robot.
