[0021] Specific embodiment one: please refer to Figures 1-5 An electric hinge for doors and windows is used to connect the window frame and the window body. It includes a fan hinge 1, a frame hinge 2, a shaft pin 3, a shaft sleeve 4, and a drive motor. The shaft sleeve 4 is sleeved outside the shaft pin 3, and the shaft sleeve 4 is rotationally connected with the shaft pin 3. One end of the shaft pin 3 is fixedly connected with the output end of the drive motor to drive the shaft pin 3 to rotate. The fan hinge 1 and the frame hinge 2 are respectively sleeved at both ends of the shaft sleeve 4, the fan hinge 1 is located on the upper side of the frame hinge 2, and the fan hinge 1 and the frame hinge 2 are respectively rotationally connected with the shaft sleeve 4. The fan hinge 1 is detachably connected with the window body, and the frame hinge 2 is detachably connected with the window frame.

[0022] The fan hinge 1 includes a fan hinge tube 11 and a fixing piece 12. The fixing piece 12 is fixedly arranged outside the fan hinge tube 11, the fixing piece 12 protrudes radially along the fan hinge tube 11, and the end face of the fixing piece 12 is fixedly connected with the outer circumferential surface of the fan hinge tube 11. The fan hinge tube 11 is nested at the upper end of the shaft sleeve 4, and the fan hinge tube 11 is rotationally connected with the shaft sleeve 4 to drive the fan hinge 1 to rotate. The fixing piece 12 is detachably connected with the window body through a screw. In this embodiment, the fixing piece 12 is connected with the window body through a countersunk head hexagonal screw 13, the fixing piece 12 is slid into a fan slot opening on the side of the window body, and when the fixing piece 12 reaches a suitable position, the countersunk head hexagonal screw 13 is used for installation.

[0023] The frame hinge 2 includes a frame hinge tube 21 and a positioning block 22. The positioning block 22 is fixedly arranged outside the frame hinge tube 21, the positioning block 22 protrudes radially along the frame hinge tube 21, and the end face of the positioning block 22 is fixedly connected with the outer circumferential surface of the frame hinge tube 21. The frame hinge tube 21 is nested at the lower end of the shaft sleeve 4, and the frame hinge tube 21 is rotationally connected with the shaft sleeve 4. The positioning block 22 is detachably connected with the window frame through a screw. In this embodiment, the positioning block 22 is connected with the window frame through a round head screw 23, the positioning block 22 is clamped into a frame slot, and the round head screw 23 is used for installation.

[0024] It should be noted that the number of electric hinges can be multiple, which can be adjusted according to the actual rotation strength required by the window body. Multiple electric hinges are evenly arranged between the window frame and the window body to connect the window frame and the window body. At the same time, the upper and lower sliding rails between the window body and the window frame can be reserved when the electric hinge is installed, so as to reduce the upper and lower bearing stress of the electric hinge.

[0025] The drive motor is electrically connected with an external switch to control the opening and closing of the window body through the external switch key. The drive motor output end is provided with a planetary reducer, and the drive motor output end and the planetary reducer are transmissionally connected. It should be noted that the fan hinge 1 and the frame hinge 2 are always rotationally connected with the shaft sleeve 4 to avoid the window being unable to be closed due to power failure.

[0026] Specific embodiment two: an electric hinge for doors and windows, the same as specific embodiment one, the difference is that it also includes a rain sensor. The rain sensor is arranged outside the window. The rain sensor is used to detect whether it is raining. The rain sensor is connected with the driving motor control system through Bluetooth. When the rain sensor detects that it is raining outside the window, the control system controls the driving motor to make the window body and the window frame close to each other. When the rain sensor does not detect that it is raining outside the window, the control system controls the driving motor to make the window body and the window frame open to each other. By setting the rain sensor, the window can be closed in time to avoid rain falling into the house.
