Description

Technical Field

[0001] This utility model relates to the field of pull-up window technology, specifically a manual-electric integrated door and window drive mechanism and a pull-up window. Background Technology

[0002] Pull-up windows, which open up and down, offer advantages such as excellent ventilation, good airtightness, and space-saving design, making them widely used in balconies, shop windows, and other similar applications. However, larger pull-up windows, due to their weight, can be difficult to open and close manually, impacting the user experience. To address this issue, some pull-up windows have been introduced with electric actuators. However, these often malfunction during power outages or motor failures, further affecting the user experience. Utility Model Content

[0003] In order to overcome the defects in the existing technology, the present invention aims to provide a hand-held and electric integrated door and window drive mechanism and a pull-up window.

[0004] This utility model achieves its objective through the following technical solutions:

[0005] A hand-operated and electric-powered door and window drive mechanism includes a drive assembly and a transmission assembly. The drive assembly includes a manual drive device and an electric drive device. The transmission assembly includes a drive shaft, two drive gears mounted on the drive shaft, and two racks meshing with the two drive gears. The manual drive device includes a first gearbox and a handle. The first gearbox contains a first gear and a second gear, which are worm gears or bevel gears connected in a transmission connection, such that the axes of the two gears form an angle greater than 0 degrees. The handle is connected in a transmission connection to the first gear. The electric drive device includes a motor and a second gearbox connected in a transmission connection. The second gearbox contains a third gear and a fourth gear connected in a transmission connection. The output shaft of the motor is connected in a transmission connection to the third gear. The drive shaft is connected in a transmission connection to the second gear and the fourth gear. The handle or the motor can drive the drive shaft to rotate, which in turn drives the two racks to move synchronously through the two drive gears.

[0006] As a preferred technical solution, the electric drive device further includes a reduction gearbox and a clutch, wherein the motor, reduction gearbox, clutch, and second gearbox are sequentially connected and integrated together.

[0007] As a preferred technical solution, the clutch includes a drum, a dial wheel, a disk, and at least one spherical or cylindrical magnetically conductive ball. The drum is connected to the third gear for transmission. The disk is fixedly disposed outside the drum. The dial wheel includes a dial shaft and a dial tooth disposed at one end of the dial shaft. The other end of the dial shaft passes through the disk and is connected to the output end of the reduction gearbox for transmission. The dial tooth and the ball are located inside the drum. The inner circumferential wall of the drum is provided with at least one groove for the ball to be partially embedded. When the motor drives the dial wheel to rotate relative to the drum, it can drive the ball to be thrown out and partially inserted into the groove, thereby driving the drum to rotate synchronously. When the motor stops or the drum speed is greater than that of the dial wheel, the ball can be attracted by the disk and disengage from the groove, thereby automatically disengaging the clutch.

[0008] As a preferred technical solution, the clutch further includes a fixedly installed non-magnetic disk, the front of which is smooth and flat and covers the port of the roller, and the magnetic disk is flatly disposed on the back of the non-magnetic disk.

[0009] As a preferred technical solution, the transmission shaft passes through the shaft holes of the second gear and the fourth gear in sequence and is connected to them for transmission. The shaft holes of the second gear and the fourth gear, as well as the transmission shaft, are all non-circular structures, so that the second gear and the fourth gear can transmit rotation to the transmission shaft.

[0010] As a preferred technical solution, the handle is a crank structure, with one end of the handle having a plug-in part for detachable insertion with the first gear, and the other end of the handle having a grip part for a person to hold.

[0011] As a preferred technical solution, the first gearbox is further provided with a locking mechanism for locking the first gear and / or the second gear.

[0012] As a preferred technical solution, it also includes a lifting auxiliary device, which includes a slider for rotatably connecting with the movable window sash and for slidingly connecting with the frame, and a spring seat for fixedly installing on the frame. The spring seat is provided with several sets of springs, each spring extending out of the spring seat and connected to the slider.

[0013] A pull-out window includes a frame, a movable window sash movably installed within the frame and capable of reciprocating up and down, and a fixed window sash fixedly installed within the frame. The pull-out window also includes the hand-operated integrated door and window drive mechanism described in any of the above-mentioned embodiments. The first gearbox and motor are fixedly installed on the fixed window sash or the frame, and the two racks are respectively vertically fixed on the left and right sides of the movable window sash. The handle or motor can drive the transmission shaft to rotate, thereby driving the movable window sash to move up and down through the two transmission gears and racks to open or close the window.

[0014] Compared with existing technologies, the hand-electric integrated door and window drive mechanism and pull-up window provided by this utility model have the following advantages: By setting a drive shaft and simultaneously setting a manual drive device and an electric drive device on the drive shaft, the window can be opened and closed by either driving the drive shaft to rotate with a motor or by manually cranking the handle to drive the drive shaft to rotate; moreover, by utilizing the torque of the handle and / or the reduction ratio of the gear set in the first gearbox, the manual opening of the window can be made less strenuous; and because the drive shaft rotates and synchronously drives the left and right sides of the movable window sash through the two gears set on it, the movable window sash runs smoothly and is not prone to jamming when moving up and down; and by using a gear and rack mechanical transmission method to drive the movable window sash to move up and down, the transmission is more stable.

[0026] Example 1:

[0027] like Figure 1-7As shown, a hand-operated and electric-electric integrated door and window drive mechanism includes a drive assembly and a transmission assembly. The drive assembly includes a manual drive device 1 and an electric drive device 2. The transmission assembly includes a drive shaft 3, two drive gears 4 mounted on the drive shaft 3, and two racks 5 meshing with the two drive gears 4 respectively. The manual drive device 1 includes a first gearbox 11 and a handle 12. The first gearbox 11 contains a first gear 111 and a second gear 112. The first gear 111 and the second gear 112 are worm gears or bevel gears that are connected in a transmission manner, so that the axes of the first gear 111 and the second gear 112 form an angle greater than 0 degrees. In this embodiment, the first gear 111 is preferred. The axes of the first gear 111 and the second gear 112 are perpendicular, facilitating the user to drive the first gearbox 11 via the handle 12. One end of the handle 12 is connected to the first gear 111. The electric drive device 2 includes a motor 21 and a second gearbox 22 connected in transmission. The second gearbox 22 contains a third gear 221 and a fourth gear 222 with parallel axes and connected in transmission. The output shaft of the motor 21 is connected to the third gear 221. The transmission shaft 3 passes through the shaft holes of the second gear 112 and the fourth gear 222 in sequence and is connected to them in transmission. The handle 12 or the motor 21 can drive the transmission shaft 3 to rotate, which in turn drives the two racks 5 to move synchronously through the two transmission gears 4. In this embodiment, the gear ratio of the first gear 111 and the second gear 112 can be 1; in other embodiments, the gear ratio can also be less than 1, which reduces the output speed and increases the torque, making it easier for the user to crank the handle; the gear ratio can also be greater than 1, which increases the output speed and decreases the torque, allowing the user to crank the handle to raise and lower the movable window sash more quickly. In other embodiments, the drive shaft 3 may also be connected to the shaft holes of the second gear 112 and the fourth gear 222 by other gears; the third gear 221 and the fourth gear 222 in the second gearbox 22 may also be bevel gears or helical gears with non-parallel axes; the number of electric drive devices 2 may also be multiple; these other embodiments are not shown in the drawings.

[0028] This embodiment provides a hand-held and electric integrated door and window drive mechanism, which is generally installed on doors and windows as an accessory for opening or closing them. Taking its installation on a pull-out window as an example, ... Figure 1 As shown, it has the following advantages: By setting a drive shaft 3 and simultaneously setting a manual drive device 1 and an electric drive device 2 on the drive shaft 3, the window can be opened and closed by either driving the drive shaft 3 to rotate via the motor 21 or by manually cranking the handle 12 to drive the drive shaft 3 to rotate; moreover, by utilizing the torque of the handle 12 and / or the reduction ratio of the gear set in the first gearbox 11, the manual window opening can be made more labor-saving; and since the drive shaft 3 drives the left and right sides of the movable window sash synchronously via the two gears set on it when rotating, the movable window sash runs smoothly and is not prone to jamming when moving up and down.

[0029] As a preferred embodiment, the electric drive device 2 further includes a reduction gearbox 23 and a clutch 24. The motor 21, reduction gearbox 23, clutch 24, and second gearbox 22 are sequentially connected and integrated together. Preferably, the clutch 24 includes a roller 241, a dial wheel 242, a disk 243, and at least one spherical or cylindrical magnetically conductive ball 244. The roller 241 is connected to the third gear 221. The disk 243 is fixedly disposed outside the roller 241. The dial wheel 242 includes a dial shaft 2421 and a dial tooth 2422 disposed at one end of the dial shaft 2421. The other end of the dial shaft 2421 passes through the disk 243 and is connected to the output end of the reduction gearbox 23. The dial tooth 2422 and... The ball bearing 244 is located inside the drum 241. The inner circumferential wall of the drum 241 is provided with at least one groove 2411 for the ball bearing 244 to be partially embedded. When the motor 21 drives the dial wheel 242 to rotate relative to the drum 241, it can cause the ball bearing 244 to be thrown out and partially inserted into the groove 2411, thereby driving the drum 241 to rotate synchronously. When the motor 21 stops or the speed of the drum 241 is greater than that of the dial wheel 242, the ball bearing 244 can be attracted by the disk 243 and disengage from the groove 2411, thereby automatically disengaging the clutch 24. In this embodiment, the disk 243 is preferably made of permanent magnet material, the ball bearing 244 is made of magnetically conductive iron material, and the drum 241, dial wheel 242, etc. are made of non-magnetically conductive materials. The working principle of the clutch 24 is as follows: When the motor 21 rotates in the forward or reverse direction, it can drive the dial 242 to rotate relative to the drum 241. Therefore, under the combined action of the push of the dial 2422 and centrifugal force, the ball 244 can break free from the magnetic attraction of the disk 243 and move outward until it is partially stuck in the groove 2411 of the drum 241. The dial 2422 continues to rotate, which will drive the drum 241 to rotate through the ball 244 exposed in the groove 2411, thereby driving the transmission shaft 3 to rotate through the second gearbox 22, that is, realizing the engagement state of the clutch; when the motor 21 stops, or when the motor 21 does not stop but external force intervenes (such as the user manually) When the drive device 1 opens and closes the window, it drives the roller 241 and the dial shaft 2421 to rotate in the same direction and the speed is greater than the speed of the dial shaft 2421. The ball 244 has free space to move and can quickly disengage from the groove 2411 of the roller 241 under the magnetic attraction of the disk 243. At this time, the dial tooth 2422 is disengaged from the roller 241. The rotation of the roller 241 will not interfere with the dial wheel 242 and the motor 21, that is, the clutch is disengaged. If the motor 21 is still running and the external force stops intervening, the dial wheel 242 will quickly push the ball 244 back into the groove 2411 of the roller 241 to realize the clutch engagement.It should be noted that since the motor 21 (or reduction gearbox 23) itself has some clearance, when the motor 21 stops, even without setting a separate program to make the motor 21 reverse, the ball 244 can still get some free space. Of course, if the motor 21 stops and is slightly reversed, the ball 244 can get more free space.

[0030] As a preferred embodiment, the clutch 24 further includes a fixedly mounted non-magnetic disk 245. The front of the non-magnetic disk 245 is smooth and flat, covering the port of the roller 241, while the magnetic disk is flatly mounted on the back of the non-magnetic disk 245. By setting the non-magnetic disk 245, and ensuring that its front is a smooth, one-piece structure, the resistance to the movement of the ball bearing 244 on the non-magnetic disk 245 is reduced. Furthermore, the magnetic shielding effect of the non-magnetic disk 245 prevents the ball bearing 244 from directly adhering to the magnetic disk 243. When the dial wheel 242 rotates and pushes the ball bearing 244, it is easier for the ball bearing 244 to detach from the magnetic disk 243 under centrifugal force and embed into the groove 2411. Therefore, the engagement and disengagement of the clutch are smoother, and jamming and wear are less likely to occur. The clutch can also be disengaged at any time by manual intervention when the motor 21 is rotating, and it can quickly return to the engaged state when manual intervention is stopped, making it convenient to use.

[0031] As a preferred embodiment, the reduction gearbox 23 in this embodiment includes a housing 231 and three stages of reduction gear sets connected in series, namely a first-stage reduction gear set, a second-stage reduction gear set, and a third-stage reduction gear set. Each stage of the reduction gear set includes a fixed sleeve 232, a rotating frame 233, three planetary gears 234, and a drive gear 235 concentrically arranged inside the fixed sleeve 232. The inner sidewall of the fixed sleeve 232 is provided with an internal gear ring 2321. The front surface of the rotating frame 233 is provided with a plurality of mounting shafts 236 evenly spaced along the circumferential direction. Each planetary gear 234 is respectively fitted onto the mounting shaft. A mounting shaft 236 allows rotation relative to the rotating frame 233. The outer sides of each planetary gear 234 mesh with the internal gear ring 2321, and the inner sides mesh with the drive gear 235. The drive gear 235 of the first-stage reduction gear set is connected to the output shaft of the motor 21. The drive gears 235 of the remaining reduction gear sets are fixedly connected to the back of the rotating frame 233 of the preceding reduction gear set. The back of the rotating frame 233 of the third-stage reduction gear set has a connector 237 for connecting the shift shaft 2421 of the clutch 24. The gears and gear ring on the first-stage reduction gear set are mutually meshing helical gears. By using helical gears in at least one stage of the planetary reduction mechanism, the meshing process between the teeth is a gradual process, with the force on the teeth gradually increasing and then decreasing. This results in a longer meshing time, a larger contact area, and reduced stress, leading to better meshing performance, smoother operation, lower noise, and stronger load-bearing capacity. By setting the first-stage reduction gear set to use helical gears for each gear and the gear ring, the characteristics of helical gears can be effectively utilized to smoothly transition the torque transmitted by the drive shaft of motor 21 and the high-speed rotation. At the same time, it avoids the high cost problem caused by using helical gears in all stages of the reduction gear set.

[0032] As a preferred embodiment, the shaft holes of the second gear 112 and the fourth gear 222, as well as the transmission shaft 3, are all non-circular structures, so that the second gear 112 and the fourth gear 222 can transmit rotation to the transmission shaft 3.

[0033] As a preferred embodiment, the handle 12 is a crank structure, one end of the handle 12 is provided with a plug-in part for detachable insertion with the first gear 111, and the other end of the handle 12 is provided with a grip part for a person to hold.

[0034] As a preferred embodiment, the first gearbox 11 is further provided with a locking mechanism for locking the first gear 111 and / or the second gear 112. The locking mechanism may be a pin respectively provided on the first gearbox 11, and a corresponding insertion hole provided on the first gear 111 and / or the second gear 112, or other structures capable of achieving the locking function (not shown in the figures). By providing the locking mechanism, the first gearbox 11 can be locked when the window does not need to be opened or closed, thereby locking the movable window sash and improving security.

[0035] As a preferred embodiment, the device further includes a lifting auxiliary device 6. The lifting auxiliary device 6 includes a slider 61 for rotatably connecting to the movable window sash and for slidingly connecting to the frame, and a spring seat 62 for fixed installation on the frame. The spring seat 62 contains several sets of springs 621, each spring 621 extending from the spring seat 62 and connected to the slider 61. By providing the lifting auxiliary device 6, the elasticity of the springs 621 can be used to distribute the weight of the movable window sash, thereby making it easier to open the window using the handle 12 or the motor 21, and reducing the requirements for the performance and size of the motor 21.

The pull-out window also includes the hand-electric integrated door and window drive mechanism of Embodiment 1, wherein the first gearbox 11 and the motor 21 are fixedly installed on the window frame of the fixed window sash 102, and the drive shaft 3 passes through the first gearbox 11 and the motor 21 in sequence. The fixed window sash 102 is also provided with a plurality of support bearings 7 for supporting the drive shaft 3 at intervals. The two racks 5 are respectively vertically fixedly installed on the left and right sides of the movable window sash 101. The sliding grooves on both sides of the frame 100 are provided with a fixedly connected coil spring seat 62 and a slidably connected slider 61. The two sliders 61 are also connected to the left and right sides of the movable window sash 101 respectively through a pin 63 or the drive shaft 3. The handle 12 or the motor 21 can drive the drive shaft 3 to rotate, thereby driving the movable window sash 101 to move up and down through the two transmission gears 4 and the racks 5 to realize the opening or closing of the window. In other embodiments, the first gearbox 11 and the motor 21 may also be fixedly mounted on the frame 100; these embodiments are not shown in the accompanying drawings.
