Description

Technical Field

[0001] This application relates to the field of electric door and window technology, and in particular to the structure of electric door and window drive assembly. Background Technology

[0002] Electric doors and windows are a modern door and window system that uses electricity to open and close doors and windows. The working principle of electric doors and windows mainly relies on an electric drive and control system. By controlling the magnitude and direction of the current, the speed and direction of the motor can be changed, thereby driving the opening and closing of the door or window. Specifically, the motor inside the electric window opener transmits power to the window frame through a transmission mechanism (such as gears, chains, screws, etc.), realizing the opening and closing of the window. Electric doors are usually equipped with a door closer; when the door is opened, the door closer, like a spring, is compressed and then released, automatically closing the door.

[0003] In existing technologies, locking doors and windows usually requires an additional fixing device, which cannot be coordinated with the drive structure of electric doors and windows. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to solve the above-mentioned problems by constructing an electric door and window drive assembly structure.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: an electric door and window drive assembly structure, including a push assembly for pushing the sash on both sides of the window frame and a drive assembly for driving the push assembly installed at the bottom of the window frame. The push assembly includes a drive screw rotatably connected to both sides of the window frame. A sliding block is slidably disposed on the drive screw. A rectangular groove is opened in the middle of the sliding block. A drive nut threadedly connected to the drive screw is disposed in the rectangular groove. The drive nut and the rectangular groove are slidably connected. A drive rod is rotatably disposed on one side of the sliding block. The other end of the drive rod is rotatably connected to the sash. A locking assembly for locking the sash is disposed at the bottom of the sliding block.

[0006] Furthermore, the locking assembly includes a locking block slidably connected to the drive screw, a locking nut threadedly connected to the drive screw in the middle of the locking block, a linkage screw threadedly provided on the locking block, the linkage screw and the drive screw being perpendicular and meshing with each other, a fastener fixedly provided on the locking block, the fastener having a locking hole, the linkage screw passing through the fastener, a locking member fixedly provided on the sector, a locking cylinder fixedly provided on the locking member, a locking screw threadedly provided inside the locking cylinder, a through hole for the linkage screw to be inserted into one side of the locking cylinder, and a linkage assembly for keeping the sliding block and the locking block close together provided between the sliding block and the locking block.

[0007] By adopting the above technical solution, the drive component drives the drive screws on both sides to rotate, which in turn drives the locking nut and the drive nut to rotate. The drive nut will first slide in the rectangular groove, while the locking nut will drive the linkage screw to rotate, thereby causing the locking screw to disengage from the locking hole. At this time, the drive nut just reaches one side of the sliding block, pushing the drive rod to open the fan.

[0008] Furthermore, the linkage component includes connecting rods inserted into both sides of the sliding block and the locking block. A connecting strip is fixedly provided at the upper end of the connecting rod, and a spring is provided between the connecting strip and the sliding block. One side of the spring is fixedly connected to the connecting strip, and the other side is fixedly connected to the sliding block.

[0009] By adopting the above technical solution, when the fan is closed, the drive motor reverses, and the drive nut simultaneously drives the drive nut and the locking nut. Since the locking block is below, it will drive the sliding block to descend together through the connecting rod. When the locking block reaches the bottom, the drive nut in the sliding block is still at the upper end of the rectangular groove. At this time, the linkage screw will enter the through hole in the locking cylinder, driving the locking screw to rotate and insert into the locking hole of the fastener.

[0010] Furthermore, the drive assembly includes a drive motor mounted on the window frame. A drive rod is fixedly installed on one output end of the drive motor, and a manual drive device is installed on the other side. A driven rod is installed on the side of the manual drive device away from the drive motor. The driven rod is rotatably connected to the window frame. A drive bevel gear is fixedly installed at the end of both the driven rod and the drive rod. A driven bevel gear is fixedly installed at the bottom of the drive screw. The drive bevel gear and the driven bevel gear mesh with each other.

[0011] By adopting the above technical solution, the drive motor drives the drive rod on one side and the driven rod on the other side, which in turn drives the driven bevel gear of the drive screw through the two drive bevel gears, causing the drive screw to rotate.

[0012] Furthermore, the manual drive device includes a drive housing connected to one side of the drive motor, a rotating shaft rotatably mounted on the drive housing, a linkage bevel gear fixedly mounted at the bottom of the rotating shaft, a driving bevel gear fixedly mounted on the output end of the drive motor away from the drive rod, the linkage bevel gear and the driving bevel gear meshing with each other, and a rotating bevel gear fixedly mounted on the side of the driven rod close to the drive motor, the rotating bevel gear and the linkage bevel gear meshing with each other.

[0013] By adopting the above technical solution, the window can also be opened and closed manually. By driving the rotating shaft, the bottom linkage bevel gear can be driven, thereby driving the rotating bevel gear on one side and driving the bevel gear, causing the driving rods and driven rods on both sides to rotate.

[0014] Furthermore, the upper end of the rotating shaft is provided with a mounting shell mounted on the window frame. The mounting shell and the rotating shaft are rotatably connected. A driven gear is fixedly connected to the upper end of the rotating shaft. The driven gear is rotatably connected to the mounting shell. A drive gear is also rotatably mounted on the mounting shell. The drive gear meshes with the driven gear. A drive hole is opened in the middle of the drive gear.

[0015] By adopting the above technical solution, in order to facilitate manual driving in this application, a matching drive handle can be used, which is inserted into the drive hole and rotated to drive the drive gear to rotate, and then drive the driven gear to rotate, so that its rotating shaft rotates.

[0016] Furthermore, a sealing cap is provided at the upper end of the drive housing.

[0017] By adopting the above technical solution, the sealing cover can prevent foreign objects from entering the drive hole when not in use.

[0018] Furthermore, a mounting magnet is embedded inside the sealing cover, and an adsorption magnet is installed inside the mounting shell.

[0019] By adopting the above technical solution, the installation of magnets and the setting of adsorption magnets facilitate the installation of the opening and closing sealing cover.

[0020] In summary, this application offers the following beneficial technical advantages: When installing the drive device, simply embedding the drive structure into the hollow cavity and fixing it is sufficient; no cumbersome secondary processing is required, easily achieving automated door and window operation. Simultaneously, the protrusion extending from the upper frame near the lower frame perfectly matches the groove on the lower frame, enhancing not only the overall structural stability of the window frame but also ensuring the load-bearing capacity and wind pressure resistance of the doors and windows.

[0021] Even more thoughtfully, a sealing strip is fixedly installed between the upper and lower frames. This detailed design effectively prevents the intrusion of external factors such as dust and rainwater, providing comprehensive protection for the drive structure. At the same time, the sealing strip further enhances the thermal insulation and soundproofing performance of the doors and windows, creating a more comfortable and quiet living environment for users.

[0022] Furthermore, the installation structure fully considers future maintenance and upgrade needs. Because the drive structure is cleverly concealed within the openwork cavity, maintenance or upgrades can be easily performed by simply disassembling a portion of the window frame profile, significantly reducing maintenance costs and improving the sustainable use of doors and windows.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] Example, refer to Figure 1 The electric door and window drive assembly structure includes a push assembly for pushing the sash 11 on both sides of the window frame 1 and a drive assembly for driving the push assembly installed at the bottom of the window frame 1. The push assembly includes a drive screw 34 rotatably connected to both sides of the window frame 1. A sliding block 4 is slidably arranged on the drive screw 34. A rectangular groove is opened in the middle of the sliding block 4. A drive nut 41 threadedly connected to the drive screw 34 is arranged in the rectangular groove. The drive nut 41 and the rectangular groove are slidably connected. A drive rod 3 is rotatably arranged on one side of the sliding block 4. The other end of the drive rod 3 is rotatably connected to the sash 11. A locking assembly for locking the sash 11 is arranged at the bottom of the sliding block 4.

[0031] The locking assembly includes a locking block 42 slidably connected to the drive screw 34, a locking nut 43 threadedly connected to the drive screw 34 in the middle of the locking block 42, a linkage screw 49 threadedly provided on the locking block 42, the linkage screw 49 and the drive screw 34 being perpendicular and meshing with each other, a fastener 47 fixedly provided on the locking block 42, the fastener 47 having a locking hole, the linkage screw passing through the fastener 47, a locking member 48 fixedly provided on the fan 11, a locking cylinder 50 fixedly provided on the locking member 48, a locking screw 500 threadedly provided inside the locking cylinder 50, a through hole for the linkage screw 49 to be inserted into on one side of the locking cylinder 50, and a linkage assembly for keeping the sliding block 4 and the locking block 42 close together provided between the sliding block 4 and the locking block 42.

[0032] The drive assembly drives the drive screws 34 on both sides to rotate, which in turn drives the locking nut 43 and the drive nut 41 to rotate. The drive nut 41 will slide in the rectangular groove first, while the locking nut 43 will drive the linkage screw 49 to rotate, thereby causing the locking screw 500 to disengage from the locking hole. At this time, the drive nut 41 just reaches one side of the sliding block 4, pushing the drive rod 3 to open the fan 11.

[0033] The linkage component includes a connecting rod 45 inserted into both sides of the sliding block 4 and the locking block 42. A connecting strip 44 is fixedly installed on the upper end of the connecting rod 45. A spring 46 is installed between the connecting strip 44 and the sliding block 4. One side of the spring 46 is fixedly connected to the connecting strip 44 and the other side is fixedly connected to the sliding block 4.

[0034] When fan 11 is closed, drive motor 2 reverses, and drive nut 41 drives both drive nut 41 and locking nut 43. Since locking block 42 is below, it will drive sliding block 4 to descend together through connecting rod 45. When locking block 42 reaches the bottom, drive nut 41 in sliding block 4 is still at the upper end of rectangular groove. At this time, linkage screw 49 will enter through hole in locking cylinder 50, driving locking screw 500 to rotate and insert into locking hole of fastener 47.

[0035] The drive assembly includes a drive motor 2 mounted on the window frame 1. A drive rod 3 is fixedly installed on one output end of the drive motor 2, and a manual drive device is installed on the other side. A driven rod 31 is installed on the side of the manual drive device away from the drive motor 2. The driven rod 31 is rotatably connected to the window frame 1. A drive bevel gear 32 is fixedly installed at the end of both the driven rod 31 and the drive rod 3. A driven bevel gear 33 is fixedly installed at the bottom of the drive screw 34. The drive bevel gear 32 and the driven bevel gear 33 mesh with each other.

[0036] The drive motor 2 drives the drive rod 3 on one side and the driven rod 31 on the other side. Through the drive bevel gears 32 on both sides, the driven bevel gear 33 of the drive screw 34 is driven to rotate the drive screw 34.

[0037] The manual drive device includes a drive housing 21 connected to one side of the drive motor 2. A rotating shaft 22 is rotatably mounted on the drive housing 21. A linkage bevel gear 23 is fixedly mounted at the bottom of the rotating shaft 22. A driving bevel gear 25 is fixedly mounted on the output end of the drive motor 2 away from the drive rod 3. The linkage bevel gear 23 and the driving bevel gear 25 mesh with each other. A rotating bevel gear 24 is fixedly mounted on the side of the driven rod 31 close to the drive motor 2. The rotating bevel gear 24 meshes with the linkage bevel gear 23.

[0038] In this application, the window can also be opened and closed by manual drive. By driving the rotating shaft 22, the bottom linkage bevel gear 23 can be driven, thereby driving the rotating bevel gear 24 on one side and the bevel gear 25, so that the driving rod 3 and the driven rod 31 on both sides can be rotated.

[0039] The upper end of the rotating shaft 22 is provided with a mounting shell 5 installed on the window frame 1. The mounting shell 5 and the rotating shaft 22 are rotatably connected. The upper end of the rotating shaft 22 is fixedly connected with a driven gear 27. The driven gear 27 and the mounting shell 5 are rotatably connected. A drive gear 28 is also rotatably provided on the mounting shell 5. The drive gear 28 and the driven gear 27 mesh. A drive hole 29 is opened in the middle of the drive gear 28.

[0040] In this application, for easier manual driving, a matching drive handle can be used, which is inserted into the drive hole 29 and rotated to drive the drive gear 28 to rotate, which in turn drives the driven gear 27 to rotate, causing its rotating shaft 22 to rotate.

[0041] A sealing cover 51 is provided at the upper end of the drive housing. The sealing cover 51 is provided to prevent foreign objects from entering the drive hole 29 when not in use.

[0042] The sealing cover 51 has an embedded mounting magnet 52, and the drive housing has an installed adsorption magnet 53.

[0043] The installation of magnet 52 and magnetic magnet 53 facilitates the installation of the opening and closing sealing cover 51.

[0044] Specific implementation process: When the window needs to be opened, the drive motor 2 installed on the window frame 1 is first started. The output end of the drive motor 2 drives the drive bevel gear 32 to rotate via the drive rod 3 (used in automatic mode) or a manual drive device. The drive bevel gear 32 meshes with the driven bevel gear 33 at the bottom of the drive screw 34, thereby driving the drive screw 34 to rotate on both sides of the window frame 1. As the drive screw 34 rotates, the drive nut 41 on the sliding block 4 slides in the rectangular groove, while pushing the sliding block 4 to move along the drive screw 34. Since the locking nut 43 on the locking block 42 also rotates with the drive screw 34, the linkage screw 49 will rotate accordingly, thereby releasing the lock on the locking screw 500 (the locking screw 500 disengages from the locking hole). When the sliding block 4 moves to a certain position, the drive rod 3 on it will push the window sash 11 to open. During the movement of the sliding block 4, the linkage components (connecting rod 45, connecting bar 44, and spring 46) keep the sliding block 4 and the locking block 42 close together to ensure the stability of the entire system.

[0045] When the window needs to be closed, the drive motor 2 reverses, causing the drive screw 34 to rotate in the opposite direction. Since the locking block 42 is located below the sliding block 4 and is connected by the connecting rod 45, the two will descend synchronously. When the locking block 42 reaches the bottom, the drive nut 41 in the sliding block 4 is still at the upper end of the rectangular groove. As the drive screw 34 continues to rotate, the linkage screw 49 will enter the through hole in the locking cylinder 50 and drive the locking screw 500 to rotate and insert into the locking hole of the fastener 47, thus locking the window. The sliding block 4 continues to descend until the drive nut 41 returns completely to the rectangular groove, completing the window closing process.

[0046] When manual operation is required, first open the sealing cover 51 at the top of the drive housing. The sealing cover 51 is attracted to the magnetic magnet 53 inside the drive housing by the mounting magnet 52 embedded inside, making it easy to open and close. Insert the matching drive handle into the drive hole 29 in the middle of the drive gear 28. By rotating the drive handle, the drive gear 28 is rotated, which in turn drives the driven gear 27 and the rotating shaft 22 to rotate. The linkage bevel gear 23 at the bottom of the rotating shaft 22 meshes with the drive bevel gear 25 on the output end of the drive motor 2 away from the drive rod 3, and at the same time meshes with the rotating bevel gear 24 on the driven rod 31 near the drive motor 2, thereby driving the drive rods 3 and the driven rod 31 on both sides to rotate. By following the above steps for opening or closing the window, the window can be opened or closed manually.

[0047] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
