[0030] The driving wheel 10 is made of rubber and is in rolling connection with the slide rail 6.

[0031] 1. Manual operation mode:

[0032] The device is provided with a wireless remote controller. By pressing the buttons of the remote controller, the device receives the remote control signal, and the control circuit executes according to the instruction direction. The reduction motor 8 rotates, the reduction motor 8 drives the output shaft 9 to rotate, the output shaft 9 drives the driving wheel 10 to rotate, and the driving wheel 10 and the slide rail 6 are used to generate friction force to drive the window sash to move in the specified direction. When the window sash moves to the limit position, the limit position signal is sensed by the limit switch 12 on the device, the position signal is transmitted to the controller, and the controller recognizes the position signal and terminates the driving signal. The window sash stops moving, and the reverse is the same.

[0033] 2. Automatic window closing mode when it rains:

[0034] The device is provided with a rainwater sensing module. When raindrops fall on the rainwater sensing module, the sensor sends a high-level signal to the control circuit, and the control circuit receives the rainwater signal and immediately executes the reduction motor 8 to work and execute the window closing action. When the window is closed in place, the limit switch 12 on the device feeds back a signal to the controller, and the controller stops driving and terminates the work.

[0035] 3. Light energy charging:

[0036] The device is provided with a solar photovoltaic module, and the power supply in the device is a rechargeable battery. The photovoltaic module charges the battery at any time when the light meets the conditions, ensuring the standby and working time of the device.

[0037] Working principle:

[0038] The device is an integrated structure, which is divided into a box body 4, a rainwater sensing plate 15, a solar panel 14, and a hanging plate 5. The box body 4 is a rectangular parallelepiped shape, the rainwater sensing plate 15 is a plate-shaped part, which is attached to the top of the box body 4, and the solar panel 14 is a plate-type glue-dripping plate, which is attached to the outer side of the box body 4. The box body 4 has a partition 7 that divides it into upper and lower parts. The box body 4 is internally provided with an integrated direct-current reduction motor 8, a control circuit board 11, a limit switch 12, and a power supply 13. The reduction motor 8 is in the form of a straight output shaft and is fixed in a horizontal state inside the box body 4. The output shaft 9 is provided with a driving wheel 10. A strip-shaped opening is formed in the lower side of the box body 4 at the position of the driving wheel 10 to avoid the driving wheel 10. Because the radius of the driving wheel 10 is greater than the sum of the thickness of the reduction motor 8 and the thickness of the lower side of the box body 4 by about 3 mm, after the reduction motor 8 is fixed, the outer circle of the driving wheel 10 is exposed by about 3 mm from the lower side of the box body 4, which ensures that the bottom of the box body 4 will not touch the window slide rail 3 and the lower frame 1 of the window frame when the driving wheel 10 moves on the slide rail 6.

[0039] Two limit switches 12 are fixed on the lower side of the partition plate 7. The limit switches 12 are selected from small micro switches. The fixed positions of the limit switches 12 are respectively located at the middle positions of the front and back directions of the left and right side edges of the partition plate 7. The contact pieces of the limit switches 12 respectively face the left and right sides, and the contact pieces extend about 7mm from the edges of the partition plate 7. The partition plate 7 is fixed at the upper position of the speed reducer motor 8, and the limit switches 12 and the speed reducer motor 8 are kept a certain gap to avoid mutual interference. The left and right side surfaces of the box body 4 are respectively holed at the positions of the contact pieces of the limit switches 12. The size and shape of the holes are slightly larger than the cross section of the contact pieces to ensure that the contact pieces are not interfered by the box body 4. The control circuit board 11 is attached and installed on the distal position of the limit switches 12 on the lower plane of the partition plate 7. The control circuit board 11 has a remote control signal receiving circuit, a direct current power supply wiring port, an input line, a rainwater sensing signal receiving circuit, a signal wiring port and a wire, a limit signal receiving terminal, and a motor forward and reverse drive circuit, which is equipped with a motor drive output wiring port. The two leads of the speed reducer motor 8 are respectively connected to the drive output wiring port of the control circuit board 11. The normally closed ends of the limit switches 12 on the left and right sides are connected to the limit signal terminal of the control circuit board 11 by wires. A wire hole with a diameter of 6mm is opened in the space between the two limit switches 12 on the partition plate 7. The two signal lines of the rainwater sensing signal port on the control circuit board 11, together with the direct current power supply input line, pass through the wire hole to the upper part of the partition plate 7. A charging control board is fixed on the left side of the upper part of the partition plate 7. The charging control board has charging input and output interfaces. A 6V charging battery pack is fixed on the right side of the upper part of the partition plate 7. The power input line of the control circuit board 11 and the positive and negative leads of the charging battery pack are respectively connected to the positive and negative power output terminals of the charging control board. A wire hole is opened at the position of the distal end of the partition plate 7 on the upper part of the box body 4. The rainwater sensing signal line of the control circuit board and the input line of the charging control board pass through the wire hole on the distal vertical surface of the box body 4. The output lines are respectively connected to the rainwater sensing plate 15 and the solar panel 14. The hanging plate 5 is fixed to the right side of the box body 4 by screws. The hanging plate 5 is a rectangular thin plate with a thickness of 1mm. The lower end of the hanging plate 5 is bent to a U-shaped hook with a thickness and height of about 3mm. Two screw fixing holes are opened on the hanging plate 5. The hook is located on the lower side. The bottom of the hook is about 7-8mm away from the lower end of the box body 4. Thus, the window opener is completely configured.

[0040] Debugging: the remote control battery is installed in the remote control, and the left and right moving buttons are pressed. When the remote control electrically opens the window, the driving wheel 10 on the box body 4 starts to rotate. The driving wheel 10 generates directional power due to the rolling friction with the lower side sliding rail 6, and the window sash moves to open. When the box body 4 moves to the opposite window sash, the limit switch 12 touches the opposite window sash, and the limit switch 12 gives a limit signal. The control circuit board 11 recognizes the limit signal and stops the driving output. The window sash stops moving. At this position, the limit switch 12 is always in a pressed state, and the window sash will not move in the opening direction no matter how the remote control is operated. When the remote control is operated to close the window, the window sash will move in the opposite direction to close the window. When the window sash moves to the closed position, the opposite position switch of the box body 4 touches the window frame, generating a limit signal. After the control circuit board 11 receives the limit signal, it immediately stops the driving output, and the window sash stops moving. There is a limit adjustment work here. When closing the window, the limit position of the window sash may not be completely closed, that is, the phenomenon of stopping the closing action. Therefore, the length of the limit switch 12 needs to be adjusted according to the actual closing state. When adjusting, only the length of the limit switch 12 needs to be shortened according to the distance that is not in place. It should be noted that it must not be too short, otherwise the main box will not be able to stop when the window is closed.

[0041] Regarding rainwater sensing debugging, under normal circumstances, only testing is required, and no debugging is required. When testing, the window sash can be opened remotely. After opening, water droplets are dropped on the rainwater sensing plate 15 at the top of the box body 4. It is observed whether the window sash performs the closing action. When the rainwater automatically closes the window, the window sash performs the same action as the remote control closing the window, that is, the window sash automatically stops when it reaches the closing position. It should be noted that when the rainwater automatically closes the window and the rainwater sensing plate 15 is not dry, it is recommended not to perform the remote opening operation, because at this time the main box still recognizes the rain state and will automatically execute the closing action.
