Description

Technical Field

[0001] The invention relates to the field of doors and windows, and in particular to a lightweight large side-hung window which can be opened and closed automatically. Background Art

[0002] A hung window is a window installed on the wall for lighting and ventilation. Most of the existing hung windows are top-hung windows or bottom-hung windows. A top-hung window is a window that is hinged to the window frame at the top and opens outward, while a bottom-hung window is a window that is hinged to the window frame at the bottom and opens inward. However, the opening angles of top-hung windows and bottom-hung windows are limited, which makes the ventilation effect unsatisfactory. Therefore, the offset hung window came into being. The offset hung window is a hung window that is hinged to the window frame on both sides. It has a large opening angle and has both ventilation and lighting effects.

[0003] However, the existing partially hung windows are mostly small in size and are mainly used in places with large traffic such as shopping malls and office buildings. Most of them are opened manually, and the hanging windows on high floors require auxiliary tools such as ladders to close. This way of closing windows is not only inefficient but also labor-intensive. Therefore, most of the existing hanging windows control the opening and closing of the hanging windows through a driving mechanism. The existing driving mechanism can still have a higher driving force for hanging windows with lighter weight, but for large hanging windows, the driving force requires a more powerful motor to control. However, the greater the power, the larger the size of the motor. This will cause the motor to affect the beauty of the window. If the motor is installed in the window frame, the thickness of the window frame will increase, thereby causing the window frame to become larger in size, affecting the overall beauty of the window. Summary of the invention

[0004] The purpose of the present invention is to provide a lightweight large-scale offset hung window that can be opened and closed automatically. The offset hung window adopts a large fan surface, but only requires a relatively small power motor to realize automatic opening and closing, which greatly facilitates the opening and closing operation of the offset hung window and can ensure the size of the window frame, thereby ensuring the overall beauty of the window.

[0005] The objective of the present invention is achieved through the following technical solutions:

[0006] A lightweight large-scale partially hung window that can be opened and closed automatically comprises a window frame, a hung window, a power bin, a transmission mechanism and a limit mechanism. The side walls on both sides of the hung window are hinged to the window frame via coaxial rotating shafts. The profiles at the top and bottom of the hung window are hollow structures. Counterweights are installed in the hollow profiles to make the weight of the hung windows on both sides of the rotating shaft equal. A power bin is installed above the window frame. A transmission mechanism is installed in the power bin. The bottoms of both ends of the power bin are processed with through openings aligned with the rotating shaft. The transmission mechanism is connected to the rotating shaft via the through openings. A limit mechanism for limiting the rotating shaft is provided in the window frame on one side of the rotating shaft.

[0007] The transmission mechanism includes a dual-output shaft motor, a transmission rod, a synchronous wheel, a synchronous belt, a duplex gear and a sector gear. The dual-output shaft motor is installed in a power bin, and the two output shafts of the dual-output shaft motor face two rotating shafts respectively. The output shafts of the dual-output shaft motor are connected to the transmission rod rotatably installed in the power bin, and a synchronous wheel is installed on the transmission rod above the through opening. A duplex gear aligned with the synchronous wheel is rotatably installed in a window frame on one side of the rotating shaft, and the synchronous belt is mounted on the synchronous wheel and the duplex gear. A sector gear engaged with the duplex gear is installed on the rotating shaft.

[0008] The included angle of the sector gear is 40°.

[0009] The double gears are a large gear and a small gear arranged coaxially, the synchronous belt is sleeved on the small gear and the synchronous wheel, and the large gear is meshed with the sector gear.

[0010] The side wall of the sector gear is processed with arc-shaped evenly arranged limiting holes, and a limiting mechanism matching the limiting holes is installed in the window frame on one side of the sector gear.

[0011] The limiting mechanism includes a motor, a gear and a rack. A gear is installed on the output shaft of the motor, and a rack is meshed on the gear. The rack is horizontally installed in the cavities on both sides of the window frame. A locking tongue for locking the fan-shaped gear is processed at one end of the rack close to the suspended window.

[0012] The limiting mechanism includes a motor, an active magnet and a passive magnet. The window frame is equipped with a motor, and the motor has a rotation angle of 0 to 180 degrees each time. The output shaft of the motor is equipped with an active magnet. A passive magnet is arranged on the inner wall of the window frame on one side of the active magnet. A limiting groove for the passive magnet to reciprocate is processed on the window frame. A pin body for locking the suspended window is formed on the side wall of the passive magnet close to the suspended window.

[0013] The limiting mechanism is a solenoid valve.

[0014] A shaking sensor is installed on the hanging window, and the shaking sensor is connected to the double-output shaft motor through a controller.

[0015] The beneficial effects of the portable large-scale side-hung window that can be opened and closed automatically provided by the present invention are:

[0016] (1) By arranging hollow profiles at the top and bottom of the hung window and installing counterweights in the profiles to make the weight of the hung windows at both ends of the rotating shaft equal, the offset hung window only needs a small driving force to be opened and closed, thereby avoiding the increase in the size of the dual output shaft motor, ensuring that the size of the window frame will not be increased due to the volume of the dual output shaft motor, and ensuring the beauty of the overall hung window;

[0017] (2) By arranging a power compartment on the window frame and installing a driving mechanism in the power compartment, the driving mechanism can be prevented from being exposed, thereby ensuring the beauty of the overall hung window;

[0018] (3) By setting a limit mechanism on the window frame, the hanging window can be locked after opening or closing to prevent the hanging window from shaking. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION Example

[0028] like Figure 1 to Figure 7As shown, the portable large side-hung window 2 that can be opened and closed automatically provided in this embodiment includes a window frame 1,

[0029] The hanging window 2, the power bin 3, the transmission mechanism 4 and the limit mechanism 5, the side walls on both sides of the hanging window 2 are hinged to the window frame 1 through the coaxial rotating shaft 21, the profiles at the top and bottom of the hanging window 2 are hollow structures, and the counterweight blocks 22 are installed in the hollow profiles to make the weight of the hanging windows 2 on both sides of the rotating shaft 21 equal. Of course, it is difficult to achieve absolute balance, and it is only necessary to make the weight difference at both ends of the rotating shaft 21 extremely small. If necessary, the weight of the hanging window 2 below the rotating shaft 21 is slightly greater than that of the hanging window 2 above. The counterweight block 22 is set to reduce the power when driving the hanging window 2 to rotate, so as to achieve the purpose of reducing the power of the transmission mechanism 4. If the rotating shaft 21 is located in the middle of the hanging window 2, the counterweight block 22 is not needed. The power bin 3 is installed above the window frame 1, and the transmission mechanism 4 is installed in the power bin 3. The bottoms of both ends of the power bin 3 are processed with through holes 31 aligned with the rotating shaft 21. The transmission mechanism 4 includes a double output Axle motor 41, transmission rod 42, synchronous wheel 43, synchronous belt 44, duplex gear 45 and fan gear 46, the dual output shaft motor 41 is installed in the power bin 3, the two output shafts of the dual output shaft motor 41 are respectively facing the two rotating shafts 21, the output shafts of the dual output shaft motor 41 are connected to the transmission rod 42 rotatably installed in the power bin 3, the synchronous wheel 43 is installed on the transmission rod 42 above the through hole 31, a duplex gear 45 aligned with the synchronous wheel 43 is rotatably installed in the window frame 1 on one side of the rotating shaft 21, the duplex gear 45 is a large gear and a small gear that are coaxial and fixedly connected, the synchronous belt 44 is mounted on the small gear and the synchronous wheel 43, a fan gear 46 meshing with the large gear of the duplex gear 45 is installed on the rotating shaft 21, the angle of the fan gear 46 is 40°, and in order to facilitate the installation of the fan gear 46, the rotating shaft 21 is a D-type shaft.

[0030] like Figure 4 As shown, the side wall of the sector gear 46 is processed with limiting holes 47 evenly arranged in an arc shape with the rotating shaft 21 as a circle, and a limiting mechanism 5 is installed in the window frame 1 on one side of the sector gear 46 to cooperate with the limiting holes 47 for locking the hanging window 2.

[0031] The limiting mechanism 5 can be implemented in this way, such as Figure 5 As shown, the limiting mechanism 5 includes a motor 511, a gear 512 and a rack 513. The gear 512 is mounted on the output shaft of the motor 511, and the rack 513 is meshed with the gear 512. The rack 513 is horizontally mounted in the cavities on both sides of the window frame 1. The rack 513 is processed with a lock tongue 514 near one end of the suspended window for locking the sector gear 46. When in use, the motor 511 drives the gear 512 to rotate, and when the gear 512 rotates, it drives the rack 513 to reciprocate, so that the lock tongue 514 installed on the rack 513 is inserted into the limiting hole 47 or pulled out of the limiting hole.

[0032] The limiting mechanism 5 can also be implemented in this way, such as Figure 6 As shown, the limiting mechanism 5 includes a motor 521, an active magnet 522 and a passive magnet 523. The motor 521 is installed on the window frame 1, and the active magnet 522 is installed on the output shaft of the motor 521. The passive magnet 523 is provided on the inner wall of the window frame 1 on one side of the active magnet 522. The window frame 1 is processed with a limiting groove for the reciprocating motion of the passive magnet 523. The limiting groove will limit the rotation of the passive magnet 523 to prevent the magnetic pole position of the passive magnet 523 from changing. The passive magnet 523 is integrally formed with a pin body 524 for locking the hanging window on the side wall close to the hanging window. The rotation angle of the motor 521 each time is 0 to 180 degrees. When in use, the motor 521 drives the active magnet 522 to rotate 180°. At this time, the positive pole on the active magnet 522 is opposite to the positive pole on the passive magnet 523, and the negative pole on the active magnet 522 is opposite to the negative pole on the passive magnet 523. Under the push of the magnetic force, the passive magnet 523 slides in the limiting groove toward the end away from the active magnet 522 until the pin body 524 is inserted into the limiting hole 47; when opened, the motor 521 drives the active magnet 522 to rotate 180° again. At this time, the positive pole on the active magnet 522 is opposite to the negative pole on the passive magnet 523, and the negative pole on the active magnet 522 is opposite to the positive pole on the passive magnet 523. The passive magnet 523 is attracted to the active magnet 522, and the pin body 524 is pulled out of the limiting hole 47.

[0033] The most convenient implementation method of the limit mechanism 5 is to directly use the electromagnetic valve 53, such as Figure 3 , Figure 4 , Figure 7 As shown, the closing member of the electromagnetic valve 53 is used as a limiting part inserted into the lock hole. When in use, the electromagnet of the electromagnetic valve 53 is energized, and the closing member on the electromagnetic valve 53 is controlled to reciprocate by adsorption or ejection to achieve the limiting of the hanging window.

[0034] The limiting mechanism 5 is inserted into the corresponding limiting hole 47 to realize opening at different angles. The limiting holes 47 located at both ends of the arc correspond to the closing of the hanging window 2 and the opening at the maximum angle, respectively.

[0035] In order to prevent damage caused by the heavy load on the rotating shaft 21 in windy weather, a swing sensor 6 is installed on the hanging window 2. The swing sensor 6 is connected to the dual-output shaft motor 41 and the limit mechanism 5 through a controller. The swing amplitude of the hanging window 2 can be detected by the swing sensor 6. If the wind is strong, the controller controls the limit mechanism 5 to open, and then the dual-output shaft motor 41 drives the hanging window to close, and then the limit mechanism 5 locks the hanging window 2.

[0036] The shaking sensor 6 can be installed at any position of the hanging window, preferably in the cavity at the upper and lower ends of the hanging window, which can not only obtain a more accurate vibration amplitude, but also avoid the shaking sensor 6 being exposed and affecting the overall appearance of the hanging window.

[0037] A detachable maintenance plate is installed on the inner wall of the power compartment 3 to facilitate maintenance of the power mechanism.

[0038] The method of using the present invention is:

[0039] The power compartment is fixed in the window hole, and then the hanging window is installed under the power compartment. Then the hanging window 2 is rotatably installed on the window frame 1 through the rotating shaft 21. Then the double output shaft motor 41 of the transmission mechanism 4 and the transmission rod 42 equipped with the synchronous wheel 43 are installed in the power compartment 3, and the synchronous belt 44 is installed on the synchronous wheel 43. Then the synchronous belt 44 is passed through the through hole 31, and then the fan gear 46 is installed on the rotating shaft 21. Then the double gear 45 is installed in the window frame 1 on one side of the fan gear 46, and the large gear of the double gear 45 is meshed with the fan gear 46, and then the synchronous belt 44 is installed on the small gear of the double gear 45. On the top, the large gear is driven to rotate by the small gear. Since the faster the rotation speed of the hanging window 2 is, the stronger the impact force generated is, the rotation speed of the rotating shaft 21 can be reduced by driving the large gear to rotate by the small gear, so as to avoid the hanging window 2 colliding with the window frame 1 due to the fast speed during the opening and closing process. In addition, since the angle of the sector gear 46 is only 40°, it can prevent the hanging window 2 from excessively rotating, causing the top hanging window 2 to collide with the bottom window frame 1. After the hanging window 2 is rotated into place, the limiting mechanism 5 will promptly insert the lock tongue 514 or the pin body 524 into the corresponding limiting hole 47 to prevent the hanging window 2 from shaking due to the lack of limiting after it is rotated into place.

[0040] When encountering strong winds after the hanging window 2 is opened, since the two sides of the hanging window 2 are hinged to the window frame 1 only by the rotating shaft 21, in order to prevent excessive wear of the rotating shaft 21, a shaking sensor 6 is installed in the hanging window 2. If the hanging window 2 shakes due to strong wind after it is opened, the shaking sensor 6 will send the shaking information to the controller, and the controller line controls the limit mechanism 5 to leave the fan gear 46. Then the controller controls the dual-output shaft motor 41 to rotate and control the hanging window 2 to close. When the hanging window 2 is closed, the limit mechanism 5 locks the fan gear 46 again to prevent the hanging window 2 from moving.

[0041] When the limiting mechanism 5 needs maintenance, it is only necessary to open the maintenance panel on the power compartment 3 to perform maintenance without disassembling the hanging window 2, which greatly improves the maintenance efficiency.

[0042] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and inventive concept provided by the present invention shall be included in the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits the description of known components and processing technologies and processes to avoid unnecessary limitation of the present invention.
