Description

Technical Field

[0001] This utility model belongs to the field of robot edge-assisted rolling technology, and particularly relates to an edge-assisted rolling device for a window cleaning robot. Background Technology

[0002] Window cleaning robots, as a commonly used modern automated cleaning component, primarily function to clean the exterior surfaces of windows, thereby enhancing the aesthetics of interior windows. However, existing window cleaning robots often require an auxiliary rolling device fixed to the edge to ensure smooth movement when the robot's edge encounters an obstacle. Furthermore, existing window cleaning robot edge auxiliary rolling devices lack alarm components, meaning they cannot alert nearby staff when subjected to external impacts, indicating the robot may be unable to move. Utility Model Content

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Reference Figures 1-4An edge-assisted rolling device for a window cleaning robot includes a fixed shell 1 and connecting pieces 2. Connecting pieces 2 are fixedly connected to the top and bottom of the fixed shell 1. The fixed shell 1 provides fixing points for the connecting pieces 2, pressure sensors 3, shock-absorbing layer 9, and luminous strip 10 connected to its outer surface and interior. The connecting pieces 2 are fixedly connected to the top and bottom of the fixed shell 1, providing fixing points for a flashlight 4 and a buzzer 5 fixedly connected to its outer surface. Transmission pieces 6 are fixedly connected to the front of the two pressure sensors 3, providing connection points for transmission rollers 7 fixedly connected to their outer surfaces. The transmission rollers 7 are rotatably connected to the front of the transmission pieces 6. The transmission rollers 7 move along the edge of the window cleaning robot... When the window cleaning robot moves to the outer surface of the external obstruction component, the drive roller 7 rotates. To ensure continuous movement of the window cleaning robot, a shock-absorbing layer 8, made of rubber, is wrapped around the outer surface of the drive roller 7. When the drive roller 7 comes into contact with the external obstruction component, the shock-absorbing layer 8 partially absorbs the impact force, thereby improving the smoothness of the drive roller 7's rotation. A damping layer 9, filled with liquid epoxy material, is arranged inside the inner wall of the fixed shell 1. When the impact force from the external environment is transmitted to the inside of the damping layer 9, the epoxy resin absorbs the impact force, thereby improving the stability of the fixed shell 1. For structural strength, a wrapping rod 11 is fixedly connected to the inner side of the fixed shell 1. The wrapping rod 11 is fixedly connected to the inner side of the fixed shell 1, providing a connection point for the extension rod 12 that is fitted inside it, and also providing a fixing point for the extension rod 12 that is fixedly connected inside it. There are two wrapping rods 11, and the extension rod 12 is fitted to the inner side of the wrapping rod 11. The extension rod 12 is fitted to the inner side of the wrapping rod 11, providing a fixing point for the spring 13 that is fixedly connected inside it, and also providing a fixing point for the fixing piece 14 that is fixedly connected to its tail end. The extension rod 12 can extend or retract to adjust its extension length. The spring 13 is fixedly connected inside the wrapping rod 11. Inside the wrapping rod 11, when the impact force of the external environment is transmitted to the outer surface of the device, the spring 13 undergoes elastic deformation, accumulating elastic potential energy inside, driving the extension rod 12 to return to its original position. The tail end of the spring 13 is fixedly connected to the inside of the extension rod 12. The tail ends of the two extension rods 12 are fixedly connected to fixing plates 14. The fixing plates 14 are fixedly connected to the tail ends of the extension rods 12, providing fixing points for the threaded fixing holes 15 that are opened through the outer surface of the fixing plates 14. The outer surface of the fixing plates 14 is provided with threaded fixing holes 15. When it is necessary to fix the device, the external bolts can be inserted into the threaded fixing holes 15 by external force to complete the overall fixation of the device. There are four threaded fixing holes 15.

[0022] Reference Figures 1-2A pressure sensor 3 is fixedly connected to the front of the fixed shell 1. When the entire device is subjected to external obstacles and the pressure sensor 3 is transmitted to the inside of the pressure sensor 3, the pressure sensor 3 transmits electrical energy to the inside of the flash lamp 4 and the buzzer 5 respectively. There are two pressure sensors 3. The top of one connecting piece 2 is fixedly connected to the flash lamp 4. When electrical energy is transmitted to the inside of the flash lamp 4 through the pressure sensor 3, the flash lamp 4 flashes at a high frequency to remind the robot user that the window cleaning robot's movement is restricted. The bottom of the other connecting piece 2 is fixedly connected to the buzzer 5. When electrical energy is transmitted to the inside of the buzzer 5 through the pressure sensor 3, the small lever inside the buzzer 5 vibrates at a high frequency and emits a sharp sound to remind the robot user that the window cleaning robot's movement is restricted.

[0023] Reference Figure 1 A luminous strip 10 is fixedly connected to the outer surface of the fixed shell 1. The luminous strip 10 is attached to the outer surface of the fixed shell 1 and emits light at night, scattering light into the external environment to assist the user in determining the robot's position at night. There are two luminous strips 10, and the luminous strips 10 are located outside the pressure sensor 3.

[0024] The functional principle of this utility model can be explained through the following operation: First, the external bolt is inserted into the threaded fixing hole 15 by external force to complete the overall fixation of the device. When the window cleaning robot moves to the outer surface of the external obstruction component, the transmission roller 7 rotates to ensure that the window cleaning robot can continue to move. When the device is subjected to excessive pressure, which may cause damage or prevent movement, the impact force is transmitted to the inside of the pressure sensor 3. At this time, the pressure sensor 3 transmits electrical energy to the inside of the flash lamp 4 and the buzzer 5 respectively. The flash lamp 4 flashes at high frequency, and the small paddle inside the buzzer 5 vibrates at high frequency, emitting a sharp sound to remind the robot user that the window cleaning robot's movement is restricted.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
