The driving mechanism a drives the chain 15 to rotate as a whole in a counterclockwise direction, and the chain 15 drives the movable frame 3 to descend through the connecting plate 4. Optionally, the bottom end surface of the movable frame 3 is provided with a connecting rod mounting hole, and the top end of the connecting plate 4 is disposed in the connecting rod mounting hole.

[0028] According to the present invention, a fixed frame 2 is provided, a movable frame 3 that moves vertically within the fixed frame 2, a connecting plate 4 whose top end is connected to the bottom end surface of the movable frame 3, a chain 15 integrally connected to the connecting plate 4, and a first sprocket 14 fixedly connected to the fixed frame 2. The first end of the chain 15 is connected to a drive mechanism a, and the second end is engaged with the first sprocket 14. The drive mechanism a is capable of driving the chain 15 to rotate as a whole, thereby achieving transmission. The chain 15 drives the movable frame 3 to move up and down via the connecting plate 4, thereby achieving automatic opening and closing of doors and windows. The use of a chain drive reduces the precision requirements for the installed components and reduces costs.

[0035] According to the present invention, when the electric drive function fails, the door and window can be opened and closed by pulling the handle on the movable frame 3. During the opening and closing process, the balancing mechanism 5 can balance the weight of the movable frame 3 through the pulley 50, the connecting rod transmission assembly, and the elastic member 54 between the slide plate 52 and the fixed plate 53. At the same time, the energy storage effect of the elastic member 54 is utilized to reduce energy consumption. The present invention can realize two drive modes. When the automatic function fails, the movable frame 3 can be manually pushed and pulled to achieve the lifting and lowering movement of the movable frame 3, thus achieving both safety and practicality.

[0037] In one or more embodiments, the fixed frame rod 51 is fixedly connected to the mounting plate 6 , and the first sprocket 14 is fixedly disposed on a surface of the mounting plate 6 .

[0038] In one or more embodiments, the slide plate 52 is fixedly connected to the sliding block 55, and the sliding block 55 contacts and slides with the outer surface of the fixed frame rod 51. There is a gap between the slide plate 52 and the fixed frame rod 51, and the sliding block 55 plays a guiding role. The slide plate 52 and the sliding block 55 can slide along the fixed frame rod 51.

[0039] In one or more embodiments, the balancing mechanism 5 further comprises a sensor contact plate 57 disposed on the surface of the slide plate 52 away from the fixed plate 53. A crossbeam 21 is disposed within the fixed frame 2, positioned below the balancing mechanism 5. Two contact sensors 56 are disposed side by side on its upper surface, and the contact sensors 56 can engage with the sensor contact plate 57 through contact.

When the movable frame 3 moves downward to a certain position, the sensor contact plate 57 can contact the sensor contact plate 56 on the left side, thereby triggering a signal indicating that the side window is open. By converting the lifting motion of the door or window into horizontal motion of the sensor contact plate 57, the sensors are centrally located in an easily accessible location, improving the maintainability of the door or window.
