Description

Technical Field

[0001] This application relates to the field of window opening structure technology, and in particular to a driver for a window opening machine. Background Technology

[0002] Window actuators, also commonly known as window openers or window openers, are automated devices used to control the opening and closing of windows. These devices are widely used in situations requiring automatic or remote control of window opening and closing, such as public buildings like airports, hotels, exhibition centers, conference centers, and stadiums, as well as industrial plants and warehouses requiring ventilation and smoke extraction.

[0003] In existing technology, a motor is used to drive the window to move, thereby realizing the electric opening and closing of the window. However, if the motor circuit fails, the window will not be able to be opened or closed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a driver for a window opener, which solves the problem that the window cannot be opened when the motor of the window opening structure fails due to circuit failure.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a driver for a window opener, comprising a window frame and a drive structure on the window frame. The window frame includes a fixed frame and a rotating frame rotatably connected to the fixed frame. The drive structure includes a drive housing mounted on the rotating frame and a drive motor mounted inside the drive housing. A driving bevel gear is fixedly disposed on the output end of the drive motor. A drive inner housing is fixedly disposed on the drive housing. An adjusting rod is rotatably disposed on the drive inner housing. A driven bevel gear meshing with the driving bevel gear is fixedly disposed at the upper end of the adjusting rod. A manual drive rod is rotatably disposed on the drive inner housing. A drive hole for driving is provided at the upper end of the manual drive rod. A linkage device is provided between the manual drive rod and the adjusting rod. Opening and closing mechanisms are provided on both sides of the window frame. A drive component for driving the opening and closing mechanisms is provided at the bottom of the adjusting rod.

[0006] By adopting the above technical solution, the drive motor drives the main bevel gear, which in turn drives the driven bevel gear on the drive inner shell. The driven bevel gear will drive the adjusting rod to rotate, thereby driving the opening and closing mechanism to open and close the rotating frame on the fixed frame. When the motor has a circuit fault, by inserting the rod that matches the drive hole into the drive hole, the manual drive rod can be driven to drive the linkage device, which in turn drives the drive component to open the window on both sides.

[0007] Furthermore, the linkage device includes a driven gear rotatably connected to the drive housing, and a drive gear is fixedly mounted on the manual drive rod, with the driven gear and the drive gear meshing.

[0008] By adopting the above technical solution, adjusting the manual drive lever will drive the drive gear to rotate, and then through the rotation of the driven gear, it will drive the drive gear, thereby allowing the drive component at the bottom of the adjustment lever to drive the opening and closing structure.

[0009] Furthermore, the bottom of the adjusting rod is provided with a connecting plate mounted on the rotating frame, and the two ends of the connecting plate are provided with connecting studs, which pass through the rotating frame and are fixedly connected to the drive housing.

[0010] By adopting the above technical solution and setting up connecting studs and connecting plates, the stability between the drive housing and the rotating frame can be improved.

[0011] Furthermore, the upper end of the manual drive rod is rotatably connected to the drive housing, and a sealing cover installed on the manual drive rod is provided on the drive hole.

[0012] By adopting the above technical solution, the sealing cover can seal the drive hole without using the manual drive rod.

[0013] Furthermore, the opening and closing mechanism includes a connecting frame installed at the bottom of the rotating frame and transmission rods on both sides. Both ends of the transmission rods are fixedly provided with bevel gears, and the transmission rods are rotatably connected inside the rotating frame. The driving component includes a driving bevel gear that is fixedly connected to the bottom of the adjusting rod through the driving housing. The driving bevel gear meshes with the bevel gears of the transmission rods on both sides. Driven studs are rotatably provided on both sides of the rotating frame. The driven studs mesh with the bevel gears of the transmission rods. A sliding block is threaded onto the driven stud. A linkage rod is rotatably connected to the sliding block. The other end of the linkage rod is rotatably connected to the fixed frame.

[0014] By adopting the above technical solution, the drive bevel gear at the bottom of the adjusting rod rotates, and through meshing, drives the bevel gears on the two rotating rods to rotate, thereby driving the driven studs on both sides of the rotating frame to rotate. The threaded connection between the sliding block and the driven studs will move accordingly, thereby pushing the linkage rod on the sliding block to open the window.

[0015] Furthermore, a drive ring is rotatably connected to the output end of the drive motor, and the drive ring is rotatably connected to the inner drive housing.

[0016] By adopting the above technical solution, the drive ring can prevent the output end of the drive motor from contacting the drive inner housing, thereby ensuring the rotation speed.

[0017] Furthermore, the bottom of the drive housing is fixedly connected by screws and a rotating frame.

[0018] By adopting the above technical solution, screws are used to fix the drive housing during installation, making disassembly easier.

[0019] Furthermore, the drive housing is made of a composite material.

[0020] In summary, this application includes at least one of the following beneficial technical effects: the actuator combines both electric and manual operation modes. Under normal circumstances, the drive motor effectively transmits power to the adjusting rod through the meshing of the driving and driven bevel gears, thereby controlling the opening and closing mechanism to achieve automatic opening and closing of the window. When the motor fails to operate due to a circuit malfunction, the user can manually operate the drive rod by inserting a rod that matches the drive hole, using the linkage device to continue driving the opening and closing mechanism, ensuring that the window can be smoothly opened or closed under any circumstances, enhancing the flexibility and reliability of use.

[0021] Compact structure and high integration: By integrating key components such as the drive motor, driving bevel gear, driven bevel gear, adjusting rod, manual drive rod, and their linkage device into the drive housing and drive inner housing, a compact structural design is achieved. This design not only saves installation space but also improves the overall aesthetics and practicality, making the window opener more suitable for various window frame sizes and installation environments.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Example, refer to Figures 1-5 A driver for a window opener includes a window frame and a drive structure on the window frame. The window frame includes a fixed frame 2 and a rotating frame 21 rotatably connected to the fixed frame 2. The drive structure includes a drive housing 1 mounted on the rotating frame 21 and a drive motor 18 mounted inside the drive housing 1. A drive bevel gear 11 is fixedly mounted on the output end of the drive motor 18. A drive inner housing 10 is fixedly mounted on the drive housing 1. An adjusting rod 23 is rotatably mounted on the drive inner housing 10. A driven bevel gear 13 that meshes with the drive bevel gear 11 is fixedly mounted on the upper end of the adjusting rod 23. A manual drive rod 24 is rotatably mounted on the drive inner housing 10. A drive hole for driving is provided at the upper end of the manual drive rod 24. A linkage device is provided between the manual drive rod 24 and the adjusting rod 23. Opening and closing mechanisms are provided on both sides of the window frame. A drive component for driving the opening and closing mechanisms is provided at the bottom of the adjusting rod 23. The drive motor 18 drives the main bevel gear, which in turn drives the driven bevel gear 13 on the drive inner housing 10. The driven bevel gear 13 will drive the adjusting rod 23 to rotate, thereby driving the opening and closing mechanism to open and close the rotating frame 21 on the fixed frame 2. When the motor has a circuit fault, by inserting the rod that matches the drive hole into the drive hole, the manual drive rod 24 can be driven to drive the linkage device, which in turn drives the drive component to open the window on both sides.

[0030] In this embodiment, the linkage device includes a driven gear 16 rotatably connected to the drive housing 10, and a drive gear 17 fixedly mounted on the manual drive lever 24. The driven gear 16 and the drive gear 17 mesh. When the manual drive lever 24 is adjusted, the drive gear 17 will rotate, and then the driven gear 16 will rotate, driving the drive gear 14, thereby allowing the drive component at the bottom of the adjusting lever 23 to drive the opening and closing structure.

[0031] In this embodiment, a connecting plate 41 mounted on the rotating frame 21 is provided at the bottom of the adjusting rod 23. Connecting studs 42 are provided at both ends of the connecting plate 41, and the connecting studs 42 pass through the rotating frame 21 and are fixedly connected to the drive housing 1. The connection studs 42 and the connecting plate 41 can improve the stability between the drive housing 1 and the rotating frame 21.

[0032] In this embodiment, the upper end of the manual drive lever 24 is rotatably connected to the drive housing 1, and a sealing cover is provided on the drive hole and mounted on the manual drive lever 24. The sealing cover is provided to seal the drive hole when the manual drive lever 24 is not in use.

[0033] In this embodiment, the opening and closing mechanism includes a connecting frame 22 installed at the bottom of the rotating frame 21 and two transmission rods 33 on both sides. Both ends of the transmission rods 33 are fixedly equipped with bevel gears, and the transmission rods 33 are rotatably connected within the rotating frame 21. The driving component includes a driving bevel gear 43 whose bottom of the adjusting rod 23 penetrates through the driving housing 1 and is fixedly connected to it. The driving bevel gear 43 meshes with the bevel gears of the two transmission rods 33. Driven studs 32 are rotatably installed on both sides of the rotating frame 21, meshing with the bevel gears of the transmission rods 33. A sliding block 3 is threadedly connected to the driven stud 32, and a linkage rod 31 is rotatably connected to the sliding block 3. The other end of the linkage rod 31 is rotatably connected to the fixed frame 2. When the driving bevel gear 43 at the bottom of the adjusting rod 23 rotates, it meshes with the bevel gears on the two rotating rods, thereby causing the driven studs 32 on both sides of the rotating frame 21 to rotate. The sliding block 3, being threadedly connected to the driven stud 32, will move accordingly, thereby pushing the linkage rod 31 on the sliding block 3 to open the window.

[0034] In this embodiment, a drive ring 12 is rotatably connected to the output end of the drive motor 18, and the drive ring 12 is rotatably connected to the drive inner shell 10.

[0035] In this embodiment, the drive ring 12 prevents the output end of the drive motor 18 from contacting the drive inner housing 10, thus ensuring rotational speed. The bottom of the drive housing 1 is fixedly connected to the rotating frame 21 by screws. Screws are used for fixing the drive housing 1 during installation, making disassembly easier. The drive housing 1 is made of composite material.

[0036] Specific implementation process: A drive housing 1 is mounted on the rotating frame 21, and a drive motor 18 is configured inside. The output end of the drive motor 18 is fixedly connected to the driving bevel gear 11, while a drive inner housing 10 is fixedly mounted outside the drive housing 1. An adjusting rod 23 is rotatably mounted on the drive inner housing 10, and a driven bevel gear 13 that meshes with the driving bevel gear 11 is fixedly mounted on its upper end. This bevel gear transmission design ensures that power is effectively transmitted from the drive motor 18 to the adjusting rod 23.

[0037] To provide manual emergency operation, a manual drive rod 24 is rotatably mounted on the drive housing 10, with a drive hole at its upper end for driving. A linkage device is provided between the manual drive rod 24 and the adjusting rod 23. In this embodiment, the device includes a driven gear 16 rotatably connected to the drive housing 10 and a drive gear 17 fixedly mounted on the manual drive rod 24. Power is transmitted between the two through meshing.

[0038] Opening and closing mechanisms are provided on both sides of the window frame to realize the actual opening and closing action of the window. A driving component is connected to the bottom of the adjusting rod 23 to drive the opening and closing mechanism. In this embodiment, the opening and closing mechanism consists of a connecting frame 22 installed at the bottom of the rotating frame 21, transmission rods 33 on both sides, and driven studs 32. Both ends of the transmission rods 33 are fixedly provided with bevel gears, which mesh with the driving bevel gears 43 at the bottom of the adjusting rod 23. The driven studs 32 are rotatably disposed inside the rotating frame 21 and mesh with the bevel gears of the transmission rods 33. A sliding block 3 is threadedly connected to the driven studs 32, and a linkage rod 31 is rotatably connected to the sliding block 3. The other end of the linkage rod 31 is rotatably connected to the fixed frame 2.

[0039] When the drive motor 18 is working normally, the driving bevel gear 11 drives the driven bevel gear 13 and the adjusting rod 23 to rotate, which in turn drives the bevel gear 43, the transmission rod 33, the driven stud 32, and the sliding block 3 to automatically open or close the window. When the motor malfunctions, the user can insert the rod that matches the drive hole into the drive hole and manually rotate the manual drive rod 24. This, through the linkage device, drives the adjusting rod 23 and the opening and closing mechanism to manually open or close the window.

[0040] Furthermore, to improve the stability and durability of the drive structure, this embodiment incorporates several details. For example, a connecting plate 41 mounted on the rotating frame 21 is provided at the bottom of the manual drive lever 24. Connecting studs 42 are provided at both ends of the connecting plate 41, penetrating the rotating frame 21 and fixedly connecting to the drive housing 1. This design enhances the connection stability between the drive housing 1 and the rotating frame 21. Simultaneously, the upper end of the manual drive lever 24 is rotatably connected to the drive housing 1, and a sealing cap is provided on the drive hole to seal the drive hole when the manual drive lever 24 is not in use, preventing dust and debris from entering.

[0041] 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.
