Description

Technical Field

[0002] Traditional window opening methods often require manual operation, which is not only laborious but also inefficient. It is especially inconvenient when multiple windows need to be opened at the same time. Therefore, it is necessary to adapt the corresponding electric window opener. The electric window opener is a new type of automatic window opening / closing device that can realize automatic control of window opening / closing. This type of equipment has been widely used in modern buildings, such as shopping malls, markets, hotels, schools, hospitals, public entertainment venues, workshops, warehouses, computer rooms, etc. In these places, the automatic opening and closing control of windows is of great significance for ventilation, lighting, safety and energy saving. A multi-load window opener and its use method disclosed in announcement number CN114961498B include a window frame, a window and a transmission plate, the window frame and the upper part of the window are rotationally connected by a rotating assembly, the transmission plate and the window frame are rotationally connected by a connecting assembly, and a window extension mechanism is provided between the window and the transmission plate. The present invention relates to the technical field of window openers. The multi-load window opener and its use method, by providing a window extension mechanism, utilize a driving motor to rotate the first sprocket and the second sprocket, and drive the single-hole chain to extend outward, thereby realizing the opening operation of multiple windows, and utilizes a cylinder to drive the movement of the piston rod, so that the limit teeth on the connecting rod mesh with the second sprocket, so that the opening angle can be limited, and the driving motor can be stopped, thereby avoiding the problem of the window being closed due to external factors after it is opened, and at the same time effectively improving the efficiency of the window opener, making it more convenient to use; When the above-mentioned prior art is in use, after the window is opened, the cylinder is used to drive the movement of the piston rod so that the limit teeth on the connecting rod are meshed and connected with the second sprocket, and the opening angle can be limited. However, the operating components are complex in structure and cumbersome to operate. The use of cylinder drive increases the operating cost. In addition, since the cylinder is inconvenient to maintain, normal operation cannot be ensured when a failure or air leakage occurs, resulting in poor opening and closing firmness of the window, which can easily cause damage to the window. In addition, the opening of multiple windows mainly depends on the working drive cooperation of the drive motor. However, when the motor is damaged or fails, there is a lack of emergency measures, resulting in the inability to open it manually. The lack of manual emergency opening function means that when the electric equipment fails, there is no effective alternative, which in turn leads to the inability to meet the escape needs of personnel in an emergency, reducing the safety of use. Therefore, corresponding improvements are needed.

[0003] Announcement No. CN113775281A discloses an electric window opener, comprising a mounting guide frame, a window frame is mounted on the inner wall between the mounting guide frames, a lateral drive window opening assembly is arranged at the connection between the mounting guide frame and the window frame, a flip drive window opening assembly is arranged on the inner wall at one end of the window frame, and a dust blowing and cleaning assembly is arranged on the inner wall of the mounting guide frame; a mounting groove is arranged on the middle outer wall of one side of the window frame, a double-axis reducer is fixed on the middle inner wall of one side of the mounting groove, a double-axis motor is fixed on the outer wall of one side of the double-axis reducer, and the output shaft of the double-axis motor is connected to one end of the input shaft of the double-axis reducer; the present invention can not only open the window horizontally, but also give the user the option of flipping the window to open, so as to meet the needs of different customers to choose the window opening method in different scenes, and can automatically clean dust during use to increase the service life; The above-mentioned prior art, when in use, utilizes a dual-axis motor in conjunction with an active guide wheel to realize the lateral movement and opening and closing drive of the window. However, when in use, only a single window can be opened at a time, the window opening efficiency is low, the operation is cumbersome and inconvenient, the user experience is poor, and the use demand for rapid indoor ventilation cannot be met. In addition, in emergency situations, such as fire or earthquake, it is necessary to quickly open multiple windows for people to escape or exhaust smoke. The design that only one window can be opened at a time will seriously affect the escape efficiency, and there is a lack of escape windows. Therefore, corresponding improvements are needed; Therefore, we propose a power-off adaptive electric window opener and a method of using the same, so as to solve the above-mentioned problems.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the power-off adaptive electric window opener and the use method thereof can electrically open the window, simultaneously realize the opening of multiple windows, and realize the self-locking of the window. Furthermore, it has a power-off adaptive function, that is, in the case of an unexpected power outage, it can realize manual opening of multiple windows, and can realize the free opening and adjustment of small windows, so as to improve the flexibility of use. The specific contents are as follows: (1) When multiple windows need to be opened, the drive motor is used to drive the worm to rotate, and the worm and the worm wheel are meshed with each other, which in turn causes the worm wheel to rotate and drives the spline rotating rod to rotate. The key bar and the key slot cooperate with each other to drive the spline sleeve to rotate, and further drive the rotating disk and the flip shaft to rotate, thereby driving a group of inner frames to rotate to complete the opening of the inner frames. During this process, the rotation of the flip shaft drives the main sprocket to rotate, and cooperates with the transmission chain to make the secondary sprocket rotate the support shaft and the adjustment gear. The adjustment gear and the driven gear are meshed with each other, so that the driven gear and the rotating shaft rotate, and then drive another group of inner frames to rotate and open them, so as to realize the synchronous opening of multiple windows with multiple loads. During the window opening process, the meshing of the worm and the worm wheel is used for flipping drive. The meshing of the worm and the worm wheel is self-locking, and the window opening angle is conveniently self-locked without excessive operation, which is convenient to use; When the driving motor is accidentally damaged or the power is cut off, the rotating block is manually turned to drive the one-way screw to rotate. Under the action of the one-way screw and the thread of the lifting plate, the lifting plate, the worm gear and the spline rotating rod can be moved downward, and the support plate can slide downward along the guide groove to separate the spline rotating rod from the spline sleeve. Then the hand turntable is turned to drive the main rotating shaft and the main gear to rotate. Under the meshing action of the transition gear set, the driven gear rotates synchronously, and then drives the rotating shaft rod to rotate, so that the inner frame on the right side is turned over. In this process, under the cooperation of the transmission chain, the secondary sprocket and the main sprocket, the turning shaft rod rotates synchronously to complete the turning of the inner frame on the left side, so that the window can be opened normally and the power-off self-adaptation is realized. Even if the window is powered off, it can be opened and closed normally. The emergency effect is good, ensuring indoor air circulation, so that the window can be inspected and maintained later, and the window opening positioning can be achieved under the locking action of the locking rod. (2) The inner frame includes movable window glass and fixed window glass. Pulling the locking column downward causes the movable block and the reset spring to move downward, and the movable window glass can be manually pushed freely to flip around the horizontal axis, so that the movable window glass can be freely opened, local ventilation can be achieved, the air circulation can be more flexible and efficient, the ventilation effect can be enhanced, and the window usage functions can be diversified. At a later time, stop pulling the locking column, and under the elastic reset action of the compression spring, the reset spring can be pushed into the fixed hole to lock the opening angle of the movable window glass and adjust the opening size. It is flexible and convenient to use. In addition, in the case of damage to the large window, the movable window glass can be further opened to meet the escape needs in an emergency.
