[0002] As people's living standards improve, their requirements for smart and comfortable living environments are getting higher and higher. Therefore, the degree of home automation is getting higher and higher. People often install window openers on windows to intelligently control the opening or closing of windows. Users can remotely control the windows, which is convenient and simple to use. Even when users are away from home, they can open or close windows at any time according to their needs.

[0003] The existing Chinese utility model patent with announcement number CN215632411U discloses a manual rack push-pull window opener, including a window sash linkage, a window opener and a hand-cranked mechanism. A rack is provided in the window opener, and the rack is connected to the window sash linkage through a rack fastener. A gear sleeve meshing with the rack is provided in the window opener. The hand-cranked mechanism includes a driving rod fixedly connected to the gear sleeve, a hand-cranked gear box and a hand-cranked handle. A worm and a worm gear shaft are provided in the hand-cranked gear box, and one end of the worm gear shaft passes through the hand-cranked gear box and is fixedly connected to the hand-cranked handle. During the whole process, the staff only needs to easily turn the hand-cranked handle at a fixed point to transfer the kinetic energy of the horizontally arranged worm gear shaft to the vertically arranged driving rod and then output it to the rack, making the hand-cranked mechanism more convenient and labor-saving to use.

[0004] In the above technical solution, this type of window opener mainly controls the opening and closing of the window sashes through a hand-cranked mechanism, but this method cannot achieve automation and / or remote window sash control. At the same time, the hand-cranked mechanism requires manual operation, which is time-consuming and labor-intensive. However, if it is directly replaced with a motor drive, although automation and / or remote window sash control can be achieved, the window sash cannot be opened and closed conveniently in the event of a power outage or motor damage. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a manual-automatic integrated driving device for a window opener in view of the deficiencies of the above-mentioned prior art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a manual-automatic integrated drive device for a window opener, comprising a box body, an output gear shaft arranged in the box body and linked to the window sash, a manual window opening mechanism that drives the output gear shaft to work, and an electric window opening mechanism that drives the output gear shaft to work, the manual window opening mechanism comprising a hand-cranked gear shaft arranged in the box body, a hand-cranked handle being arranged after one end of the hand-cranked gear shaft passes through the box body, a clutch movable shaft is arranged between the hand-cranked gear shaft and the output gear shaft, a driving gear and a driven gear that can rotate on the outer circumferential surface of the clutch movable shaft are axially mounted on the clutch movable shaft, the driving gear is meshed with the hand-cranked gear shaft, the driven gear is meshed with the output gear shaft, and a mutually cooperating mechanism is arranged between the driving gear and the driven gear to achieve A transmission structure for linkage or separation, wherein one end of the clutch movable shaft corresponding to the driving gear is provided with a limiting ring platform for linkage with the driving gear axial lifting and lowering so as to approach or move away from the driven gear, an elastic member is provided between the box body and the driving gear, one end of the elastic member is against the box body, and the other end is against the driving gear, and prompts the driving gear to move in the direction of the driven gear, and a clutch control knob is provided after one end of the clutch movable shaft passes through the box body, and a plurality of high-position platforms protruding in the direction away from one end of the driving gear are provided at the clutch control knob of the box body corresponding to the clutch control knob, and the clutch control knob switches between the surface of the box body and the high-position platform, when the clutch control knob is against the surface of the box body, the driving gear and the driven gear are linked with each other, and when the clutch control knob is against the high-position platform, the driving gear and the driven gear are separated from each other.

[0007] By adopting the above technical solution, the output gear shaft is used as the main power source for opening and closing the window sash, and it is meshed and transmitted with the manual window opening mechanism and the electric window opening mechanism respectively. In order to ensure that the manual window opening mechanism is not affected when the electric window opening mechanism is working (normal working mode), a clutch structure is set. Under normal conditions, the active gear uses elastic parts to provide continuous elastic force, which prompts the active gear to move toward the driven gear and maintain linkage, so that the window opener can ensure the stability of the active gear reset in any installation orientation. When the window sash is opened and closed by electric control, it is pulled to the high platform through the clutch control knob, and then the clutch movable shaft is pulled up, and the linkage limit ring platform links the active gear to move away from the driven gear, so that the active gear The transmission structure between the clutch and the driven gear is released, realizing separation from the driven gear.

When encountering a power outage or motor damage, the clutch control knob is returned from the high platform to the surface of the box body, and the driving gear is reset to the linkage state with the driven gear due to the elastic part. At this time, turning the hand crank handle can drive the driving gear to rotate through the hand crank gear shaft, and then the driven gear drives the window sash through the output gear shaft to open and close, so that the driving gear and the driven gear are linked or separated by switching the clutch control knob, realizing the integrated design of manual and electric without interfering with each other.
