Description

Technical Field

[0001] The utility model relates to a window opener, in particular to a manual-automatic window opener. Background Art

[0002] A manual-automatic window opener is a device used to automatically open and close windows. It combines manual operation with automatic control, allowing windows to open and close automatically based on preset parameters or sensor signals. These devices are widely used in buildings to automatically control the state of windows when ventilation is required or when adjusting indoor temperature.

[0003] After searching, the patent with the announcement number CN220769208U discloses a manual-automatic window opener, which includes a gearbox for transmitting motion, an output shaft located on one side of the gearbox and connected to the gearbox, a drive motor located on one side of the gearbox and used to drive the gearbox to move, and an input shaft located on one side of the gearbox and connected to the gearbox. The output shaft is used to control the opening and closing of the window by forward and reverse rotation. The output shaft is connected to the gearbox, which is also connected to the input shaft and the drive motor. When the rotation of the output shaft needs to be electrically controlled, the drive motor is started, the transmission gearbox is activated, and the gearbox transmits power to the output shaft, driving the output shaft to rotate forward or reverse. When the rotation of the output shaft needs to be manually controlled, the input shaft is manually cranked, the input shaft transmits power to the gearbox, and the gearbox transmits power to the output shaft, driving the output shaft to rotate forward or reverse, thereby achieving manual or electric control of the movement of the window opener.

[0004] Although the existing technology can achieve a certain window opening effect during use, it has the following defects: the existing manual-automatic window opening device lacks the reverse clutch function, which causes the motor to directly drive idling when the shaft rotates, which can easily cause motor damage and malfunction. In view of this, we propose a manual-automatic window opener to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a manual-automatic window opener. When the crank is used to drive the window opener to rotate, the bridge block on the window opener affects the two magnet blocks, and the two magnet blocks are squeezed into the two magnet fixing grooves respectively. At this time, the bridge block is locked and cannot rotate anymore, thereby preventing the motor from idling, which is beneficial to protecting the motor.

[0006] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a manual-automatic window opener, comprising a shell, an electric drive mechanism arranged on the shell, and an external connecting mechanism, the shell comprising an upper shell and a lower shell fixed to the upper shell, the upper shell and the lower shell together forming an internal hollow cavity structure, which is used to accommodate the electric drive mechanism, the electric drive mechanism comprising a positioning seat, a motor fixed to one end face of the positioning seat, and a protective cover arranged on the other end face of the positioning seat, a front end shaft is provided on the motor, a bearing is installed on the outside of the protective cover, the protective cover is a cavity structure with an opening at one end and a hollow interior, and a magnet fixing groove is provided in the cavity of the protective cover, a bridging block and a magnet block are provided in the protective cover, and a positioning hole is provided on the bridging block passing through both sides thereof, the external connecting mechanism comprises a rear end shaft, a second bevel gear fixed to the outside of the rear end shaft, and a first bevel gear meshing with the second bevel gear, the rear end shaft and the front end shaft are both fitted into the positioning hole, so that when the front end shaft rotates, the rear end shaft can be driven to rotate by the bridging block.

[0007] Preferably, the positioning seat is inserted into the upper shell and the lower shell, and the positioning seat fits with the inner wall of the upper shell and the inner wall of the lower shell; so that the positioning seat is fixed in the shell and cannot move, thereby ensuring the stability of structures such as the motor and the protective cover.

[0008] Preferably, the bearing and the protective cover are both in contact with an end surface of the positioning seat away from the motor.

[0009] Preferably, there are two magnet blocks and two magnet fixing grooves, and the two magnet blocks are respectively matched with the two magnet fixing grooves; when the two magnet blocks are squeezed into the two magnet fixing grooves, the structure of the bridging block is limited, and the bridging block cannot rotate at this time, so the front end shaft will not rotate either, thereby avoiding idling of the motor.

[0010] Preferably, an external connecting shaft is provided on one side of the shell, and the external connecting shaft is fixedly connected to the rear end shaft; so that the rear end shaft can drive the external connecting shaft to rotate while rotating, and the end of the external connecting shaft away from the rear end shaft is used to connect with the relevant structure on the curtain.

[0011] Preferably, a limiting plate is provided between the protective cover and the positioning seat; the limiting plate is used to prevent the bridging block and the magnet block from falling off from the cavity of the protective cover.

[0012] Preferably, holes having the same size as the positioning holes are provided on both the protective cover and the limiting plate; the holes are used to allow the front end shaft and the rear end shaft to pass through smoothly.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention, through the electric drive mechanism, when actually used, if a person manually turns the crank to drive the external connection mechanism to work, the crank will drive the crank connecting shaft, the rear end shaft, the first bevel gear and the second bevel gear to operate, thereby making the external connection shaft operate. During this process, the rear end shaft will drive the bridge block to reverse (opposite to the direction of rotation of the motor), so that the bridge block affects the two magnet blocks, and squeezes the two magnet blocks into the two magnet fixing grooves respectively. At this time, the bridge block is locked and can no longer rotate, thereby not causing the motor to idle, which is beneficial to protecting the motor and the front end shaft on the motor.

The outer connecting mechanism 4 includes a rear end shaft 41, a second bevel gear 43 fixed to the outside of the rear end shaft 41, and a first bevel gear 42 meshing with the second bevel gear 43. The end of the first bevel gear 42 away from the rear end shaft 41 passes through the upper shell 11 and extends to the outside of the upper shell 11. An outer connecting shaft 2 is provided on one side of the shell 1. The outer connecting shaft 2 is fixedly connected to the rear end shaft 41, so that the outer connecting shaft 2 can be driven to rotate when the rear end shaft 41 rotates, and the end of the outer connecting shaft 2 away from the rear end shaft 41 is used to be connected to the relevant structure on the window.

[0024] See also Figures 4 and 5 , a front end shaft 321 is provided on the motor 32, and a bearing 33 is installed on the outside of the protective cover 34. The bearing 33 and the protective cover 34 are both fitted with the end surface of the positioning seat 31 away from the motor 32.

There are two magnet blocks 36 and two magnet fixing grooves 341, and the two magnet blocks 36 are respectively matched with the two magnet fixing grooves 341. When the two magnet blocks 36 are squeezed into the two magnet fixing grooves 341, the structure of the bridge block 35 is limited. At this time, the bridge block 35 cannot rotate, so the front end shaft 32 1 will not rotate, so as to prevent the motor 32 from idling. A positioning hole 351 is provided on both sides of the bridge block 35, and a limiting piece 37 is provided between the protective cover 34 and the positioning seat 31. A mounting groove 311 for accommodating the limiting piece 37 is provided on the positioning seat 31. The limiting piece 37 is used to prevent the bridge block 35 and the magnet block 36 from falling off from the cavity of the protective cover 34.

The hole is used to allow the front end shaft 321 and the rear end shaft 41 to pass through smoothly; the rear end shaft 41 and the front end shaft 321 are both inserted into the positioning hole 351, so that when the front end shaft 321 rotates, the bridge block 35 can be used to drive the rear end shaft 41 to rotate.

[0025] During operation of the present invention, if an electric drive mode is used, the motor 32 is powered on and drives the front end shaft 321 to rotate, and the rear end shaft 41 and the outer connecting shaft 2 are rotated by means of the bridging block 35, and the outer connecting shaft 2 drives the relevant structure on the window to rotate, thereby realizing the corresponding function; if a manual drive mode is used, it is necessary to first fix the crank assembly to the first bevel gear 42 (the installation method is the existing technology), so that the crank assembly drives the first bevel gear 42 to rotate, and then drives the second bevel gear 43, the rear end shaft 41 and the outer connecting shaft 2 to rotate, thereby realizing the corresponding function. When the manual drive mode is used, the rear end shaft 41 will drive the bridging block 35 to reverse (opposite to the direction of operation of the motor 32), so that the bridging block 35 squeezes the two magnet blocks 36 into the two magnet fixing grooves 341. After the two magnet blocks 36 enter the two magnet fixing grooves 341 respectively, the position of the bridging block 35 is just locked, thereby avoiding idling of the motor 32, which is beneficial to protecting the motor 32.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
