Description

Technical Field

[0001] The present invention relates to the technical field of lifting windows, and in particular to a lifting and lowering side pressure driving mechanism for lifting windows and the lifting window. Background Art

[0002] A sliding window generally includes a fixed frame, a fixed sash fixedly installed in the fixed frame, and a movable sash that is movably installed in the fixed frame and can move back and forth up and down to open and close the window. The fixed sash is generally located on the outside, and the movable sash is generally located on the inside. Since the window is opened and closed up and down, it has the advantages of good ventilation, no obstruction of vision, and no space occupation. It has been widely used in balconies, display windows and other usage scenarios. In order to ensure that the movable sash can be raised and lowered smoothly with low friction, a certain gap needs to be reserved between the movable sash and the fixed sash in the inside and outside directions. As a result, existing sliding windows generally have the problem of poor airtightness, which affects the sliding window's rainproof, soundproof and heat-insulating properties. In particular, the current industry standard mandates that the movable sash must be located on the inside, which results in particularly poor rainproof performance of the sliding window. When the window is closed, rainwater can easily leak into the window through the gap between the movable sash and the fixed sash. In addition, since the sliding windows are opened up and down, for larger sliding windows, the movable window sashes are usually heavier. Therefore, it is more difficult for users to directly push and pull the movable window sashes to open and close the windows, which will also affect the user experience. Summary of the Invention

[0003] In order to overcome the defects existing in the prior art, one of the tasks of the present invention is to provide a lifting and side pressure driving mechanism for a lifting window, which can not only drive the movable window sash to perform lifting and lowering movements to realize the opening and closing of the window, but also drive the movable window sash to move translationally toward the fixed window sash to increase the sealing performance of the lifting window. The second task is to provide a lifting window using the lifting and side pressure driving mechanism.

[0004] One of the tasks of the present invention is achieved through the following technical solutions:

[0005] A lifting and lowering side pressure drive mechanism for a lifting window, comprising a lifting drive assembly and at least two side pressure assemblies, the lifting drive assembly comprising a drive device, a transmission shaft, a reverser, a corner regulator, a drive gear and a rack, wherein the transmission shaft comprises two transverse axes connected in series through a reverser to make the rotation directions opposite, and two longitudinal axes respectively arranged at the back ends of the two transverse axes and respectively connected to the corresponding transverse axes through a corner regulator for vertical transmission, the other ends of the two longitudinal axes are respectively connected to a drive gear, and the opposite sides of the two drive gears are respectively used to engage with the two racks, the drive device comprises an electric drive device and / or a manual drive device that is connected to the transmission shaft and can drive it to rotate; the side pressure assembly comprises a side pressure plate and a guide column, the side pressure plate is provided with a guide groove for the guide column to be inserted and to limit its sliding, wherein the guide groove comprises an inclined groove section inclined along the inward and outward directions of the lifting window in the lifting direction, and one end of the side pressure plate is provided with an entrance for the guide column to enter the guide groove.

[0006] As a preferred technical solution, the reverser includes a reverse box, a first bevel gear, a second bevel gear and a third bevel gear rotatably arranged in the reverse box, wherein the first bevel gear and the second bevel gear are respectively connected to the opposite ends of the two horizontal shafts, and the third bevel gear is located between the first bevel gear and the second bevel gear and is engaged with the first bevel gear and the second bevel gear at the same time.

[0008] As a preferred technical solution, the guide groove also includes vertical sections arranged at both ends of the inclined groove section, and the entrance is a bell mouth; the width of the rack is greater than the width of the corresponding driving gear, so that when the driving gear slides relative to the rack within the translational motion range driven by the side pressure assembly, the driving gear and the rack will not disengage.

[0009] As a preferred technical solution, the electric drive device includes a motor, a reduction gearbox, a clutch and an output gearbox that are sequentially connected in transmission.

The brake disc is located between the brake seat and the friction plate and can move back and forth between the two. When the electromagnetic coil is energized, the brake disc can overcome the force of the reset mechanism and be adsorbed on the brake seat, thereby forming a gap between the brake disc and the friction plate. When the electromagnetic coil is de-energized, the brake disc can be tightly attached to the friction plate under the action of the reset mechanism, thereby braking the drive shaft of the motor. The reset mechanism is a spring arranged between the brake seat and the brake disc, or the reset mechanism is a permanent magnet arranged on the friction plate and capable of attracting the brake disc.

[0013] The second task of the present invention is achieved through the following technical solutions:

[0014] A lifting window comprises a fixed frame, a fixed sash fixedly installed in the fixed frame, and a movable sash movably installed in the fixed frame and capable of reciprocating up and down to realize opening and closing the window. The lifting window also includes the lifting side pressure driving mechanism described above, wherein the two racks are respectively vertically installed on the left and right sides of the movable sash, the driving device, the reverser, and the angler are fixedly installed on the fixed sash or the fixed frame, the transverse axis is arranged along the left and right directions of the fixed sash and is transmission-connected to the driving device, the longitudinal axis is arranged along the inward and outward directions of the lifting window, and the opposite sides of the two driving gears are respectively used to engage with the two racks, so that the transmission shaft can be driven to rotate by the driving device, and then the two driving gears drive the two racks and the movable sash to move up and down through the two driving gears, the guide posts of the two side pressure assemblies are respectively installed on the left and right sides of the movable sash, and the side pressure plates of the two side pressure assemblies are respectively installed on the left and right slide grooves of the fixed frame, and in the process of the movable sash moving to close the window, the guide posts can enter the guide grooves of the corresponding side pressure plates along with the movable sash, and drive the movable sash to move translationally toward the fixed sash under the guiding action of the inclined groove section.

[0015] As a preferred technical solution, a sealing strip is further provided between the movable window sash and the fixed window sash. When the movable window sash is translated toward the fixed window sash under the guidance of the inclined groove section, the sealing strip can be squeezed to improve the airtightness.

[0016] Compared with the prior art, the lifting and lowering side pressure driving mechanism for a lifting window and the lifting window provided by the present invention have the following advantages:

[0017] 1. By setting up a lifting drive assembly and a side pressure assembly, the lifting drive assembly can be used to drive the movable window sash to move up and down to realize opening and closing of the window. When the movable window sash is closed, the side pressure assembly can be used to drive the movable window sash to move toward the fixed window sash to reduce the gap between the two, thereby improving the sealing performance of the sliding window;

[0018] 2. By setting two longitudinal axes and connecting them to the two transverse axes in a vertical direction through an angle converter, the direction of the longitudinal axis is consistent with the inward and outward directions of the lifting window (that is, the axial direction of the driving gear is consistent with the translational direction of the movable window sash). In this way, when the side pressure assembly drives the movable window sash to translate toward the fixed window sash, the driving gear only needs to translate and slide relative to the convex teeth on the rack along its axial direction. There is no motion interference between the driving gear and the rack, and the width of the rack is greater than the width of the driving gear. In this way, the driving gear will not disengage from the rack during the translational sliding relative to the rack; and, by setting two transverse axes and connecting the two transverse axes in series through a reverser, the rotation directions of the two transverse axes are opposite, and then the rotation directions of the two driving gears are opposite. In this way, the opposite sides of the two driving gears can be used to drive the two racks to move synchronously in the same direction respectively, so that the two racks are respectively installed on the left and right sides of the movable window sash, thereby synchronously driving the left and right sides of the movable window sash through the two racks, so that the movable window sash runs smoothly and is not easy to get stuck when it is raised and lowered.

[0035] Example 1:

[0036] like Figure 1-12 As shown, a lifting and side pressure driving mechanism for a lifting window includes a lifting driving assembly and two side pressure assemblies 1, the lifting driving assembly includes a driving device, a transmission shaft, a reverser 4, a corner device 5, a driving gear 6 and a rack 7, wherein the transmission shaft includes two transverse shafts 31 connected in series through the reverser 4 so as to rotate in opposite directions, and two longitudinal shafts 32 respectively arranged at the back ends of the two transverse shafts 31 and respectively connected to the corresponding transverse shaft 31 through a corner device 5 for vertical transmission connection, the other ends of the two longitudinal shafts 32 are respectively connected to a driving gear 6, and the two driving gears The opposite sides of the wheel 6 are respectively engaged with the two racks 7, and the driving device is an electric driving device 2, which is connected to the transmission shaft to drive the transmission shaft to rotate; the side pressure assembly 1 includes a side pressure plate 11 and a guide column 12, and the side pressure plate 11 is provided with a guide groove 111 for inserting the guide column 12 and guiding its sliding. The guide groove 111 includes an inclined groove section 1111 inclined along the inward and outward direction of the lifting window in the lifting direction, and one end of the side pressure plate 11 is provided with an entrance for the guide column 12 to enter the guide groove 111.

[0037] The lifting and lowering side pressure drive mechanism for the lifting window provided in this embodiment is installed on the lifting window when in use. The specific structure of the lifting window is as shown in Example 2. The lifting window includes a fixed frame 101, a fixed window sash 102 fixedly installed in the fixed frame 101, and a movable window sash 103 movably installed in the fixed frame 101 and capable of reciprocating up and down to realize opening and closing of the window, wherein the fixed window sash 102 is located on the outside and the movable window sash 103 is located on the inside. In this embodiment, the specific installation method of the lifting side pressure drive mechanism is as follows: the two racks 7 are respectively installed vertically on the left and right sides of the movable window sash 103 and the convex teeth of the two racks 7 face back to back and face the fixed frame 101 on the corresponding side. The left and right corners of the movable window sash 103 adjacent to the fixed window sash 102 are respectively provided with an avoidance groove 1031 for installing the rack 7. The driving device, the reverser 4, and the angler 5 are fixedly installed at intervals on the window frame of the fixed window sash 102. The horizontal axis 31 is arranged along the left and right directions of the fixed window sash 102 (that is, the width direction of the lifting window) and is transmission-connected to the driving device. In this embodiment, the horizontal axis 31 is preferably rotatably supported by a number of support bearings 33 fixedly arranged on the fixed window sash 102. The longitudinal axis 32 is arranged along the inward and outward directions of the lifting window and the opposite sides of the two driving gears 6 are respectively engaged with the two racks 7, so that it can be driven by the driving device. The transmission shaft is driven to rotate, and then the two racks 7 and the movable window sash 103 are driven to move up and down through the two driving gears 6. The guide columns 12 of the two side pressure assemblies 1 are respectively installed on the left and right sides of the movable window sash 103, and the side pressure plates 11 of the two side pressure assemblies 1 are respectively installed on the left and right slide grooves of the fixed frame 101. In the process of the movable window sash 103 moving to close the window (preferably a short distance before the movable window sash 103 is about to complete closing the window), the guide column 12 can enter the guide groove 111 of the corresponding side pressure plate 11 along with the movable window sash 103, and drive the movable window sash 103 to move translationally toward the fixed window sash 102 under the guiding action of the inclined groove section 1111. When the movable window sash 103 completes closing the window, the distance that the movable window sash 103 moves translationally toward the fixed window sash 102 just reaches a distance that can improve the sealing performance (for example, it can just squeeze the rubber strip between the movable window sash 103 and the fixed window sash 102 to achieve sealing). In addition, it should be noted that any horizontal axis and vertical axis in this patent can be a continuous axis or a spliced ​​axis. For example, when the sliding window is relatively wide, any horizontal axis can be a spliced ​​axis formed by splicing several axis segments.

[0038] The present embodiment provides a lifting and side pressure driving mechanism for a lifting window. By setting a lifting driving component and a side pressure component 1, the lifting driving component can be used to drive the movable window sash 103 to lift and lower to realize opening and closing the window, and when the movable window sash 103 is closed, the side pressure component 1 can be used to drive the movable window sash 103 to move toward the fixed window sash 102 to reduce the gap between the two, thereby improving the sealing performance of the lifting window; by setting two longitudinal axes 32 and connecting the two transverse axes 31 in a vertical direction through the angler 5, the direction of the longitudinal axis 32 is consistent with the inward and outward direction of the lifting window (that is, the axial direction of the driving gear 6 and the translation direction of the movable window sash 103). In this way, when the side pressure component 1 drives the movable window sash When 103 moves translationally toward the fixed window sash 102, the driving gear 6 only needs to slide translationally along its axial direction relative to the convex teeth on the rack 7, and there will be no motion interference between the driving gear 6 and the rack 7; and, by setting two horizontal shafts 31 and connecting the two horizontal shafts 31 in series through the reverser 4, the rotation directions of the two horizontal shafts 31 are opposite, and thus the rotation directions of the two driving gears 6 are opposite, so that the opposite sides of the two driving gears 6 can be used to drive the two racks 7 to move synchronously in the same direction, so that the two racks 7 are respectively installed on the left and right sides of the movable window sash 103, so that the left and right sides of the movable window sash 103 are synchronously driven by the two racks 7, so that the movable window sash 103 can run smoothly and not easily get stuck when it is raised and lowered.

[0039] As a preferred solution of this embodiment, the width of the rack 7 is greater than the width of the corresponding driving gear 6, so that when the movable window sash 103 moves translationally toward the fixed window sash 102 under the drive of the side pressure assembly and drives the driving gear 6 to slide relative to the rack 7, the driving gear 6 and the rack 7 will not disengage.

[0040] As a preferred solution of this embodiment, the reverser 4 includes a reverse box 41, a first bevel gear 42, a second bevel gear 43 and a third bevel gear 44 rotatably arranged in the reverse box 41, wherein the first bevel gear 42 and the second bevel gear 43 are respectively connected to the opposite ends of the two horizontal shafts 31, and the third bevel gear 44 is located between the first bevel gear 42 and the second bevel gear 43 and is engaged with the first bevel gear 42 and the second bevel gear 43 at the same time.

[0041] As a preferred embodiment of this embodiment, the angler 5 includes an angle box 51 and a worm gear mechanism rotatably disposed within the angle box 51, axially perpendicular to and meshing with each other. A worm 52 is drivingly connected to one end of the corresponding transverse axis 31, and a worm gear 53 is drivingly connected to one end of the corresponding longitudinal axis 32. The use of two mutually perpendicular worm gear mechanisms not only achieves a vertical transmission connection between the transverse axis 31 and the longitudinal axis 32, but also provides a self-locking effect. When the drive device rotates the transverse axis 31, driving the worm 52, the worm 52 drives the worm gear 53 to rotate, thereby driving the movable window sash 103. However, when the drive device stops driving, the weight of the movable window sash 103 is transmitted to the worm gear 53 of the angler 5. The worm gear 53 does not drive the worm 52 to rotate, thereby achieving self-locking of the movable window sash 103. In other embodiments, two bevel gears or two worms 52 may be used in place of the worm gear mechanism.

[0042] As a preferred solution of this embodiment, the guide groove 111 also includes vertical sections 1112 arranged at both ends of the inclined groove section 1111, and the entrance is a bell mouth 112. This design enables the guide column 12 to enter the guide groove 111 more easily when it meets the side pressure plate 11, and when the movable window sash is in the closed state, the guide column 12 is located in the vertical section 1112 of the guide groove 111, which is convenient for positioning and prevents the guide groove 111 from accidentally sliding along the inclined groove section 1111.

[0043] As a preferred solution of this embodiment, the electric drive device 2 includes a motor 21, a reduction gearbox 23, a clutch 24, and an output gearbox 22, which are sequentially connected. The output gearbox 22 is provided with two first gears 221 and second gears 222, the drive shaft of the motor 21 being connected to the first gear 221, and one of the transverse shafts 31 being connected to the second gear 222. The motor 21 can drive the drive shaft to rotate, and then the two racks 7 are driven to move synchronously in the same direction through the two drive gears 6. Preferably, the first gear 221 and the second gear 222 are axially parallel and spaced apart, and the second gear 222 is provided with a non-circular shaft hole. The transverse shaft 31 passes through the shaft hole and the mating portion is a non-circular structure, so that the second gear 222 can transmit rotation to the transverse shaft 31. This solution enables the electric drive device 2 to be directly installed on the window frame of the fixed window sash 102 and for the transverse shaft 31 to pass through. There is no need to cut a groove in the fixed frame 101 to install the electric drive device 2, which facilitates installation and arrangement.

[0044] As a preferred solution of this embodiment, the clutch 24 includes a roller 241, a dial wheel 242, a magnetic disk 243, and at least one spherical or cylindrical magnetic ball 244, wherein the roller 241 is transmission-connected to the first gear 221, the magnetic disk 243 is fixedly arranged outside the roller 241, the dial wheel 242 includes a dial shaft 2421 and a dial tooth 2422 arranged at one end of the dial shaft 2421, the other end of the dial shaft 2421 passes through the magnetic disk 243 and is transmission-connected to the output end of the reduction gear box 23, and the dial is connected to the output end of the reduction gear box 23. The teeth 2422 and the ball bearing 244 are located within the drum 241. The inner wall of the drum 241 is provided with at least one recess 2411 for partially embedding the ball bearing 244. When the motor 21 drives the dial 242 to rotate relative to the drum 241, the ball bearing 244 is ejected until it partially engages the recess 2411, thereby driving the drum 241 to rotate synchronously. When the motor 21 stops or the speed of the drum 241 exceeds that of the dial 242, the ball bearing 244 is attracted by the magnetic disk 243 and released from the recess 2411, thereby automatically disengaging the clutch 24. In this embodiment, the magnetic disk 243 is preferably a permanent magnet, the ball bearing 244 is preferably a magnetically conductive iron material, and the drum 241 and dial 242 are preferably non-magnetic materials. The working principle of the clutch 24 is as follows: when the motor 21 rotates forward or reverse, it can drive the dial wheel 242 to rotate relative to the drum 241. Therefore, under the combined action of the push of the dial teeth 2422 and the centrifugal force, the ball 244 can escape 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 teeth 2422 continue to rotate, which will drive the drum 241 to rotate through the ball 244 exposed to the groove 2411, thereby driving the first gear 221 of the output gear box 22 to rotate through the drum 241, thus 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 using When the roller 241 and the dial shaft 2421 are driven to rotate in the same direction and the speed is greater than that of the dial shaft 2421 through the manual drive device 1 (when opening or closing the window), the ball 244 has free space to move, so that it can quickly disengage from the groove 2411 of the roller 241 under the action of the magnetic attraction of the disk 243. At this time, the dial tooth 2422 and the roller 241 are in a disengaged state, and the rotation of the roller 241 will not interfere with the dial wheel 242 and the motor 21, that is, the clutch is disengaged. At this time, 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 engage the clutch. It should be noted that, since the motor 21 (or the reduction gear box 23) itself has some matching clearance, when the motor 21 stops, even if no additional program is set to reverse the motor 21, the ball 244 can still obtain a little free space. Of course, if the motor 21 is slightly reversed after stopping, the ball 244 can obtain more free space.

[0045] As a preferred embodiment of this embodiment, the clutch 24 further includes a fixed non-magnetic disk 245. The front surface of the non-magnetic disk 245 is smooth and flat and covers the end of the roller 241. The magnetic disk is flatly mounted on the back surface of the non-magnetic disk 245. By providing the non-magnetic disk 245 and the smooth, integrated front surface of the non-magnetic disk 245, the resistance of the ball 244 when moving on the non-magnetic disk 245 is reduced. Moreover, the magnetic isolation effect of the non-magnetic disk 245 prevents the ball 244 from being directly adsorbed on the magnetic disk 243. When the dial 242 rotates and pushes the ball 244, the centrifugal force makes it easier for the ball 244 to break away from the attraction of the magnetic disk 243 and embed itself in the groove 2411. Therefore, the clutch can be engaged and disengaged more smoothly and is less likely to cause sticking and wear. The clutch can also be disengaged at any time through manual intervention while the motor 21 is rotating. When manual intervention is stopped, the clutch can quickly resume engagement, making it convenient to use.

[0046] As a preferred solution of this embodiment, the reduction gearbox 23 in this embodiment includes a reduction gearbox 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 driving gear 235 concentrically arranged in the fixed sleeve 232. The inner side wall of the fixed sleeve 232 is provided with an inner gear ring 2321. A plurality of mounting shafts 236 are evenly spaced along the circumference on the front of the rotating frame 233. The planetary gears 234 are respectively The planetary gears 234 are mounted on a mounting shaft 236 and can rotate relative to the rotating frame 233. The outer sides of each planetary gear 234 mesh with the inner ring gear 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 drive shaft of the motor 21, while the drive gears 235 of the remaining reduction gear sets are fixedly connected to the back of the rotating frame 233 of the previous-stage reduction gear set. The back of the rotating frame 233 of the third-stage reduction gear set is provided with a plug connector 237 for connecting to the shift shaft 2421 of the clutch 24. The gears and ring gears of the first-stage reduction gear set are cooperating helical gears. By using helical gears in at least one stage of the planetary reduction mechanism, the meshing process between the gear teeth is a transitional process, and the force on the gear teeth gradually increases from small to large and then decreases. This prolongs the meshing time, increases the contact area, and reduces stress, thereby achieving better meshing performance, smoother operation, lower noise, and greater load-bearing capacity during operation. By setting the gears and ring gears of the first-stage reduction gear set to be helical gears, the characteristics of the helical gears can be effectively utilized to smoothly transition the torque and high-speed rotation transmitted by the drive shaft of the motor 21, while also avoiding the high cost problem caused by using helical gears in all levels of reduction gear sets.

[0047] As a preferred solution of this embodiment, the motor 21 is connected to a brake module 25, comprising a brake seat 251, a brake disc 252, a friction plate 253, and a reset mechanism (not shown in the drawings). The brake seat 251 is fixedly connected to the motor housing and has an electromagnetic coil (not shown in the drawings) disposed therein. The friction plate 253 is fixedly connected to the drive shaft of the motor 21. The brake disc 252 is located between the brake seat 251 and the friction plate 253 and can reciprocate between the two. When the electromagnetic coil is energized, the brake disc 252 overcomes the force of the reset mechanism and is adsorbed on the brake seat 251, thereby forming a gap between the brake disc 252 and the friction plate 253. At this time, the drive shaft of the motor 21 can rotate freely. When the electromagnetic coil is de-energized, the brake disc 252 is pressed against the friction plate 253 by the reset mechanism, thereby braking the drive shaft of the motor 21. The reset mechanism is a spring disposed between the brake seat 251 and the brake disc 252, or a permanent magnet disposed on the friction plate 253 and capable of attracting the brake disc 252. By providing the brake module 25, when the electric drive device 2 stops working or there is a power outage, the drive shaft of the motor 2 can be braked by the brake module 25, thereby braking the movable window sash to prevent the movable window sash from accidentally falling.

When the user rotates the handle 81 to drive the second worm 8352, the second worm 8352 can drive the second worm gear 8453 to rotate, thereby driving the horizontal shaft 31 to rotate. However, when the user stops rotating the handle 81, when the gravity of the movable window sash 103 is transmitted to the second worm gear 8453 in the hand-cranked seat, the second worm gear 8453 will not drive the second worm 8352 to rotate, thereby achieving self-locking of the movable window sash 103. In other embodiments, two bevel gears can also be used to replace the above-mentioned worm and worm gear mechanism. In addition, the hand-cranked seat can also achieve the purpose of manually opening the window more labor-saving by setting the speed ratio of the meshing gears, adding a reduction gear set, or utilizing the torque of the handle.
