Description

Technical Field

[0001] This utility model relates to the field of lift-up window technology, specifically to a drive mechanism suitable for electric lift-up windows and a door or window having the same. Background Technology

[0002] Lift-up windows differ from traditional inward-opening, outward-opening, and ordinary sliding windows. Instead, they use a lift-up opening method. Lift-up windows have superior energy-saving and heat-insulating properties, dust prevention and noise reduction, excellent wind pressure resistance, beautiful lines, wide viewing angle, no collision with people when open, no risk of window sash falling outward, and excellent safety. Different configurations can meet the needs of high-rise commercial or residential projects with more than 30 floors, as well as super high-rise commercial or residential projects with more than 60 floors.

[0003] With the development of smart homes, the trend of electric doors and windows is significant in order to reduce manual operation and improve user experience. Currently, most electric sliding windows on the market are based on worm gear and chain drive. However, the material and processing costs of worm gear drive parts are high, and the overall structure is large. Secondly, chain drive has high operating noise and poor transmission stability.

[0004] In addition, worm gear and chain drive doors and windows generally use a single motor and single-side drive, which can easily cause the window sash to tilt or jam during use. While the dual motor and dual-side drive chain method can improve synchronization, it significantly increases the cost, requires higher driving precision, and limits the layout of the transmission device. Utility Model Content

[0005] The purpose of this utility model is to overcome the existing technical defects and provide a drive mechanism suitable for electric lifting windows. It solves the problems of window sash tilting and jamming caused by traditional single motor single-side drive, and realizes double-side synchronous transmission lifting or lowering of electric lifting windows at low cost, effectively avoiding window sash tilting.

[0006] In the first aspect, in order to solve the above-mentioned technical problems, the present invention provides a drive mechanism suitable for electric lifting windows, including a winding reel and a drive device for driving the winding reel to rotate. The two ends of the winding reel are respectively wound with a first flexible traction member and a second flexible traction member, and the winding directions of the first flexible traction member and the second flexible traction member are consistent. One end of the first flexible traction member and the second flexible traction member are both configured to extend vertically downward and are respectively used to fix to the two sides of the electric lifting window.

[0007] Furthermore, the drive mechanism for the electric sliding window also includes a first guide assembly for extending one end of the first flexible traction member vertically downward to one side of the electric sliding window and a second guide assembly for extending one end of the second flexible traction member vertically downward to the other side of the electric sliding window.

[0008] Furthermore, the first guide assembly includes a first pulley for extending one end of the first flexible traction member horizontally and a third pulley for extending vertically, such that one end of the first flexible traction member extends vertically downward after passing through the first pulley and the third pulley in sequence; the second guide assembly includes a second pulley for extending one end of the second flexible traction member horizontally and a fourth pulley for extending vertically, such that one end of the second flexible traction member extends vertically downward after passing through the second pulley and the fourth pulley in sequence; and the horizontal extension direction of one end of the first flexible traction member after passing through the first pulley is opposite to the horizontal extension direction of one end of the second flexible traction member after passing through the second pulley.

[0009] Furthermore, the drive mechanism for the electric lifting window also includes a fixed base, the winding reel is rotatably disposed on one side of the fixed base, and the first pulley and the second pulley are rotatably disposed on the fixed base and located in front of, above or below the winding reel.

[0010] Furthermore, the first pulley and the second pulley are rotatably embedded in the fixed base, and the fixed base is provided with a first cable groove for the first flexible traction member to wind around the first pulley and a second cable groove for the second flexible traction member to wind around the second pulley, and the first cable groove and the second cable groove are symmetrically arranged.

[0011] Furthermore, the upper end of the fixed base is provided with a cover plate that covers the first pulley and the second pulley.

[0012] Furthermore, the drive mechanism for electric sliding windows also includes a first pulley seat and a second pulley seat located on both sides of the fixed base, a third pulley rotatably mounted on the first pulley seat, and a fourth pulley rotatably mounted on the second pulley seat.

[0013] Furthermore, the third pulley is rotatably embedded in the first pulley seat, and the first pulley seat has a first through hole on both the side facing the fixed seat and the lower side for the first flexible traction member to pass through back and forth; the fourth pulley is rotatably embedded in the second pulley seat, and the second pulley seat has a second through hole on both the side facing the fixed seat and the lower side for the second flexible traction member to pass through back and forth.

[0014] Furthermore, the drive mechanism for the electric sliding window also includes two symmetrically arranged first and second fixing members for fixing to the two sides of the electric sliding window respectively. One end of the first flexible traction member is fixed to the first fixing member, and one end of the second flexible traction member is fixed to the second fixing member. Guide pulleys are rotatably provided on the outer side of both the first and second fixing members, and the outer peripheral surface of the guide pulleys protrudes beyond the outer end face of the first and second fixing members.

[0015] Secondly, this utility model also provides a door and window, including a fixed frame, a fixed window sash fixedly installed in the fixed frame, and an electric lifting window movably installed in the fixed frame and capable of moving up and down to realize opening and closing of the window, and also includes the driving mechanism described in any one of the first aspects, wherein one end of the first flexible traction member and the second flexible traction member is fixed to the left and right sides of the electric lifting window, and the driving device and the winding reel are installed on the fixed window sash or the fixed frame.

[0016] This utility model has the following beneficial effects: In this invention, two flexible traction components wound on the same reel are fixed to both sides of the electric lifting window. After the reel is driven by a single drive device, the two flexible traction components can be simultaneously loosened outward or wound inward to tighten. This achieves low-cost, dual-side synchronous transmission for lifting or lowering of the electric lifting window, effectively preventing window tilting. It solves the problem of window tilting and jamming caused by uneven force in traditional single-motor, single-side drive, improving operational stability and service life, and avoiding the high cost of dual-motor, dual-drive structures.

[0017] Secondly, by using flexible traction components for flexible transmission, the strict limitations imposed on the position and spatial layout of the motor by the rigid transmission in traditional electric lifting windows are solved. This achieves stable transmission of the entire window while effectively reducing the visible area of ​​the frame and enhancing the visual aesthetics.

[0018] Furthermore, the first, second, third, and fourth pulleys are rotatably mounted in the fixed base and pulley seat respectively in an embedded manner, and the flexible traction component passes between the pulley and the fixed base and pulley seat. This effectively avoids the problem of the flexible traction component detaching from the pulley during use, improving the stability and reliability of the transmission structure. Moreover, the rolling friction between the flexible traction component and the pulley results in less friction noise, smoother and quieter operation, and improved user comfort.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0021] To better understand the technical content of this utility model, the following will further introduce and explain this utility model in conjunction with the accompanying drawings and specific embodiments. It should be noted that if there are descriptions such as "first" and "second" in the text, they are used to distinguish different components, etc., and do not represent the order of priority, nor do they limit "first" and "second" to be different types.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1 like Figures 1 to 7 As shown in the figure, a drive mechanism 100 for an electric sliding window in this embodiment includes a winding reel 1 and a drive device 2 for driving the winding reel 1 to rotate. A first flexible traction member 3 and a second flexible traction member 4 are respectively wound around both ends of the winding reel 1, and the winding directions of the first flexible traction member 3 and the second flexible traction member 4 are consistent. That is, by driving the winding reel 1 through the drive device 2, the first flexible traction member can be simultaneously released outward or wound inward to retract. One end of each of the first flexible traction member 3 and the second flexible traction member 4 is configured to extend vertically downward and is used to fix to both sides of the electric sliding window 10 (e.g., ...). Figure 7As shown in the figure, the electric lifting window 10 can be lowered and raised during the process of relaxing and contracting the two flexible traction components. This achieves low-cost, dual-side synchronous transmission for lifting or lowering of the electric lifting window, effectively preventing window sash tilting. It solves the problem of window sash tilting and jamming caused by uneven force in traditional single-motor single-side drive, improves operational stability and service life, and avoids the high cost problem of dual-motor dual-drive structure.

[0024] Understandably, due to limitations in the size of the reel, the window frame size, and the layout of the drive mechanism, it is unlikely that the two flexible traction components on the reel will be positioned exactly above the sides of the motorized sliding window 10. The reel 1 is generally located above one side or the center of the motorized sliding window 10 (e.g., Figure 7 As shown), in order to pull the two flexible traction members to both sides of the electric lifting window 10, the drive mechanism also includes a first guide assembly for extending one end of the first flexible traction member 3 vertically downward to one side of the electric lifting window 10 and a second guide assembly for extending one end of the second flexible traction member 4 vertically downward to the other side of the electric lifting window 10.

[0025] In this embodiment, as Figures 1 to 7 As shown, the first guide assembly includes a first pulley 31 for extending one end of the first flexible traction member 3 horizontally and a third pulley 32 for extending vertically, so that one end of the first flexible traction member 3 extends vertically downward after passing through the first pulley 31 and the third pulley 32 in sequence, that is, the first flexible traction member first extends horizontally outward and then extends vertically downward; the second guide assembly includes a second pulley 41 for extending one end of the second flexible traction member 4 horizontally and a fourth pulley 42 for extending vertically, so that one end of the second flexible traction member 4 extends vertically downward after passing through the second pulley 41 and the fourth pulley 42 in sequence, that is, the second flexible traction member 4 first extends horizontally outward and then extends vertically downward; and the horizontal extension direction of one end of the first flexible traction member 3 after passing through the first pulley 31 is opposite to the horizontal extension direction of one end of the second flexible traction member 4 after passing through the second pulley 41, thereby pulling one end of the two flexible traction members to both sides of the electric lifting window 10 respectively.

[0026] In this embodiment, the drive mechanism further includes a fixed base 5. The winding reel 1 is rotatably mounted on one side (front or rear, upper or lower) of the fixed base 5 via a bearing. The first pulley 31 and the second pulley 41 are rotatably mounted on the fixed base 5 and are located in front of, above or below the winding reel.

[0027] Preferably, such as Figures 1 to 3As shown, the first pulley 31 and the second pulley 41 are both horizontally arranged, and the winding reel is located in front of or behind the first pulley 31 and the second pulley 41. This arrangement can effectively reduce the longitudinal installation space required for the drive mechanism. The third pulley 32 and the fourth pulley 42 are vertically arranged.

[0028] In another different implementation application case, the fixed base and drive device in the figure can be rotated 90 degrees up or down so that the winding reel is located on the upper or lower side of the fixed base. The first pulley 31 and the second pulley 41 are both vertically set on the fixed base and located on the lower or upper side of the winding reel. The fixed base requires more longitudinal installation space compared to the horizontal method. That is, the first pulley 31 and the second pulley 41 can be set horizontally or vertically, and can be flexibly set according to the installation layout. There is no limitation here.

[0029] In one embodiment, such as Figures 1 to 7 As shown, the first pulley 31 and the second pulley 41 are rotatably embedded in the fixed base 5. The fixed base 5 is provided with a first cable groove 51 for the first flexible traction member 3 to pass through the first pulley 31 and a second cable groove 52 for the second flexible traction member 4 to pass through the second pulley 4. The flexible traction member passes between the pulley and the fixed base, which can effectively prevent the flexible traction member from detaching from the pulley during use and improve the stability and reliability of the transmission structure. The first cable groove 51 and the second cable groove 52 are both right-angled grooves. The first cable groove 51 and the second cable groove 52 are symmetrically arranged so that one end of the two flexible traction members extends horizontally to opposite directions.

[0030] In one embodiment, such as Figure 4 As shown, the upper end of the fixed base 5 is provided with a cover plate 51 covering the first pulley 31 and the second pulley 41, which is used to close one side of the opening of the two cable trays, further preventing the two flexible traction components from falling off.

[0031] In one embodiment, such as Figures 1 to 7As shown, the drive mechanism also includes a first pulley seat 6 and a second pulley seat 7 located on both sides of the fixed base 5. The third pulley 32 is rotatably embedded in the first pulley seat 6. The first pulley seat 6 has a first through hole 61 on both the side facing the fixed base 5 and the lower side for the first flexible traction member 3 to pass through. That is, one end of the first flexible traction member 3 enters the first pulley seat 6 from the first through hole 61 on the side, then passes around the third pulley 32 and exits from the first through hole 61 on the lower side, so as to achieve the purpose of turning the first flexible traction member 3 by 90 degrees. Moreover, by using the interlacing and winding method, the first flexible traction member 3 avoids the first flexible traction member 3 from turning around. The problem of detachment between the second flexible traction member 4 and the third pulley 32 is addressed by the fourth pulley 42 being rotatably embedded in the second pulley seat 7. The second pulley seat 7 has second through holes 71 on both the side facing the fixed seat 5 and the bottom side for the second flexible traction member 4 to pass through. That is, one end of the second flexible traction member 4 enters the second pulley seat 7 from the second through hole 71 on the side, then passes around the fourth pulley 42 and exits from the second through hole 71 on the bottom side, so as to achieve the purpose of turning the second flexible traction member 4 90 degrees. Moreover, by using the method of passing through and around, the problem of detachment between the second flexible traction member 4 and the fourth pulley 42 is avoided.

[0032] In one embodiment, such as Figures 1 to 7 As shown, to facilitate the fixed connection between the flexible traction component and the electric sliding window, the drive mechanism also includes two symmetrically arranged first fixing components 8 and second fixing components 9 for fixing to both sides of the electric sliding window 10 respectively. One end of the first flexible traction component 3 is fixed to the first fixing component 8, and one end of the second flexible traction component 4 is fixed to the second fixing component 9. Guide pulleys 81 are rotatably provided on the outer side of both the first fixing component 8 and the second fixing component 9, and the outer peripheral surface of the guide pulleys 81 protrudes from the outer end face of the first fixing component 8 and the second fixing component 9. In this way, when the electric sliding window and the drive mechanism are installed in the door and window, the guide pulleys 81 contact the fixed frame in the door and window, so that a rotational contact is formed between the guide pulleys 81 and the fixed frame, reducing the sliding friction of the electric sliding window and improving its smoothness when sliding up and down.

[0033] Preferably, the driving device is a motor, which can drive the winding reel to rotate in the forward or reverse direction to achieve the purpose of loosening and lengthening the flexible traction member outward and winding and shortening the flexible traction member inward, thereby realizing the electric control of the electric lifting window to move up and down.

[0034] Preferably, one end of both the first flexible traction member and the second flexible traction member is fixed to the winding reel to prevent the two flexible traction members from detaching from the winding reel.

[0035] Example 2 like Figure 1-9As shown, this embodiment provides a door and window, including a fixed frame 101, a fixed window sash 102 fixedly installed within the fixed frame 101, and an electric sliding window 10 movably installed within the fixed frame 101 and capable of reciprocating up and down to achieve opening and closing. The fixed window sash 102 is located on the outside of the door and window, and the electric sliding window 10 is located on the inside of the door and window. The two sides of the inner periphery of the fixed frame are provided with slide rails for the electric sliding window 10 to slide up and down. The door and window also includes the drive mechanism 100 described in Embodiment 1. The first fixing member 8 and the second fixing member 9 are fixed vertically on the left and right sides of the electric sliding window 10 by screws. The outer periphery of the guide pulley 81 contacts the inner side of the fixed frame 101. The first pulley seat 6 and the second pulley seat 7 are located above the first fixing member 8 and the second fixing member 9 and are fixedly installed on the fixed window sash 102 or the fixed frame 101 by screws. The fixing seat 5 and the drive device 2 are located on the electric sliding window 10 and are fixedly installed on the fixed window sash 102 or the fixed frame 101 by screws.

[0036] In the above, the drive mechanism 100 is installed inside the fixed frame, and the fixed seat 5, drive device 2, first pulley seat 6 and second pulley seat 7 are all located at the top inside the fixed frame. The transmission device occupies little space and is not exposed, which can meet the current market demand for narrow sides.

[0037] In other embodiments, both the first flexible traction member and the second flexible traction member are preferably steel wire ropes.

[0038] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
