[0026] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar units or units with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0027] A convenient and practical rewinding screen window, the rewinding screen window comprises a screen, a rewinding box 1 for accommodating the screen, a pull rod 3 for pulling the screen to move, the rewinding screen window also comprises a frame 2 connected to the rewinding box 1 at one end, a transmission wheel 22 arranged at the other end of the frame 2, a driving wheel 5 and a pull rope 6, the pull rope 6 is used to connect the pull rod 3, the driving wheel 5 is used to wind the pull rope 6, the pull rope 6 is fixed to the pull rod 3 after passing through the driving wheel 22; when the rewinding screen window is closed, the driving wheel 5 rotates to wind up the pull rope 6, and the pull rope 6 drives the pull rod 3 to pull the screen out of the rewinding box 1; when the rewinding screen window is opened, the driving wheel 5 rotates to release the pull rope 6, and the screen is retracted into the rewinding box 1 under the action of the rewinding box 1.

[0028] The rewinding screen window further includes a motor 8 disposed inside the rewinding box 1, and the motor 8 drives the driving wheel 5 to rotate. The addition of the motor 8 makes the control more automated, and a switch can be used to control the forward and reverse rotation of the motor 8, thereby controlling the opening and closing of the screen. It is conceivable that a wireless switch can also be provided to achieve wireless control, and even an APP can be installed to achieve intelligent control via a mobile phone.

[0029] The rewinding screen window further comprises a hand wheel 9 arranged outside the rewinding screen window, and the hand wheel 9 drives the driving wheel 5 to rotate. Manual operation can realize the stability of opening the screen. This structure makes the original pulling operation become a rotating operation, reduces the range of motion, and is more convenient for the elderly, children and other people to use.

[0030] The rewinding screen window further includes a recycling box 7, which is used to store and release the pull cord 6. When the rewinding screen window is closed, the motor 8 drives the driving wheel 5 to extract the pull cord 6 from the recycling box 7; when the rewinding screen window is opened, the motor 8 drives the driving wheel 5 to wind up the pull cord 6, and the recycling box 7 stores the pull cord 6. The recycling box 7 is added so that the pull cord 6 obtained after the driving wheel 5 winds up has a place to put, which avoids the mutual entanglement and bloating of the driving wheel 5 after winding up a large number of pull cords 6, and increases the structural stability and aesthetics.

[0031] The pull rope 6 is fixed to both ends of the pull rod 3, and the other end of the pull rope 6 is connected to the driving wheel 5 and is wound and released by the driving wheel 5. The two-side arrangement allows both ends of the pull rod 3 to be stressed, thereby increasing the structural stability.

[0032] The frame 2 includes a main structure 20 and a plug-in plate structure 21, one end of the main structure 20 is connected to the rewind box 1, the plug-in plate structure 21 is plugged into the other end of the main structure 20, and the transmission wheel 22 is installed on the plug-in plate structure 21. This structural design makes the overall structure easier to implement and convenient for replacement in case of damage.

[0033] The rewinding screen window further comprises a control module for controlling the rotation of the motor 8 and a photoelectric sensor connected to the control module, and when the control module receives a signal of a set light intensity, it controls the forward or reverse rotation of the motor 8. This design makes the overall structure more intelligent.

[0034] In the first embodiment of the present application, the rewinding screen window in this embodiment comprises a rewinding box 1 for accommodating a barrier structure such as a screen, a pull rod 3 for driving the screen to move, a driving mechanism for driving the pull rod 3 to move, and a pull rope 6 as a transmission medium between the driving mechanism and the pull rod 3. A rewinding spring is also provided in the rewinding box 1, which is used to keep the screen tight on one hand, and can also allow the pull rod 3 to store the screen in the rewinding box 1 after being loosened.

[0035] The driving mechanism is a motor 8 disposed in the rewinding box 1, and a driving wheel 5 is disposed at the end of the motor 8. The driving wheel 5 winds the pull rope 6, thereby driving the pull rod 3 to move. The rewinding screen window also includes a frame 2, one end of which is connected to the rewinding box 1. The frame 2 is used to accommodate the up and down or left and right pulling of the pull rod 3, and the frame 2 is used to limit the pull rod 3. A transmission wheel 22 is disposed at the other end of the frame 2, and the pull rope 6 is fixed on the pull rod 3 after passing through the transmission wheel 22.

[0036] When the rewinding screen window is closed, the motor 8 rotates to drive the driving wheel 5 to wind the pull rope 6. After the pull rope 6 passes around the transmission wheel 22, the pull rod 3 is pulled to expand and close the rewinding screen window; when the rewinding screen window is closed, the motor 8 rotates to drive the driving wheel 5 to gradually loosen the pull rope 6. After the pull rope 6 passes around the transmission wheel 22, the pull rod 3 is released, and the screen is stored back into the rewinding box 1 under the action of the rewinding spring in the rewinding box 1.

[0037] Embodiment 2 of the present application adds a recovery structure of the pull cord 6 on the basis of embodiment 1. Specifically, a recovery box 7 is provided near the driving wheel 5 of the motor 8, and the recovery box 7 is used to accommodate the pull cord 6. When the rewinding screen is closed, the motor 8 drives the driving wheel 5 to extract the pull cord 6 from the recovery box 7; when the rewinding screen is opened, the motor 8 drives the driving wheel 5 to wind the pull cord 6, and the recovery box 7 stores the pull cord 6. The internal structure of the recovery box 7 is similar to that of a box ruler. On the one hand, the pull cord 6 can be extended, and on the other hand, when the pull cord 6 is not subjected to external force, it can be recovered into the recovery box 7.

[0038] In various embodiments of the present application, it is conceivable that the rewinding box 1 can not only store screens, but also store deformable window panes and other materials that are deformed and rolled into the rewinding box 1. That is, the electric screen is not limited to a screen structure that blocks mosquitoes.

[0039] In the third embodiment of the present application, the motor 8 in the second embodiment is replaced with a hand wheel 9, so that manual operation can be realized and user options are increased.

[0040] Embodiment 4 of the present application is based on Embodiment 3, but the installation direction of the rewinding screen is reversed, which can also achieve the same functions and effects.

[0041] In the present application, “when the rewinding screen window is opened” means that the screen needs to be stored in the rewinding box 1 ; and “when the rewinding screen window is closed” means that the screen needs to be pulled out from the rewinding box 1 .
