Technical Field

[0001] The utility model belongs to the technical field of window openers, and particularly relates to a dual-purpose window opener structure with a clutch mechanism. Background Art

[0002] At present, with the improvement of people's living standards, people have higher and higher requirements for the intelligence and comfort of living environment, and the degree of automation of homes is getting higher and higher; people often install electric window openers on windows to intelligently control the opening or closing of windows. Users can remotely control the windows, which is convenient and simple to use.

[0003] However, existing electric window openers usually use an electric method to open and close windows, and cannot achieve manual and automatic switching. In particular, since electric window openers usually have a self-locking function, when the power system fails, the window cannot be opened or closed, causing unnecessary troubles and inconveniences to users' daily lives and work environments.

The cam is rotatably arranged in the groove, and the linkage ball is movably arranged in the groove.

[0009] In the above-mentioned window opener structure with a dual-purpose clutch mechanism, the control piece is made of magnetically attractive metal, and the linkage ball is made of a magnet. The linkage ball can cooperate with the control piece for magnetic attraction.

[0025] The following are specific embodiments of the present invention in combination with the drawings, and the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0026] Embodiment 1:

[0027] A window opener structure with a dual-purpose clutch mechanism, as Figures 1 to 5 shown, includes a housing 1, a rotary drive source 2, a control board 3, a worm gear 4, a worm 5, an output shaft 6, a clutch assembly 7, and a reduction gear set 8. The rotary drive source 2 is electrically connected to the control board 3, and the output shaft 6 is drivingly connected to the reduction gear set 8. In this embodiment, a battery 19 is provided inside the housing 1, and the battery 19 is electrically connected to the control board 3 and the rotary drive source 2. As another solution, the control board 3 and the rotary drive source 2 can also be directly connected to an external power supply through wires.

[0028] In this embodiment, the rotary drive source 2 is preferably a motor. As another solution, other drive sources with a rotary function can also be used. The output end of the rotary drive source 2 is connected to the worm 5. The worm gear 4 is rotatably arranged on the mounting bracket 13, and the worm 5 meshes with the worm gear 4.

[0029] The clutch assembly 7 includes a clutch driving gear 71, a clutch driven gear 72, and a linkage member 73. The linkage member 73 includes a cam 731, a control piece 732, and a linkage ball 733.

[0030] The clutch driven gear 72 and the cam 731 are rotatably arranged on a rotating shaft 11, and the rotating shaft 11 is rotatably arranged on the mounting bracket 13. A linkage shaft 12 is integrally provided on the cam 731, and the clutch driving gear 71 is coaxially connected to the linkage shaft 12. When the clutch driving gear 71 rotates, it can drive the cam 731 to rotate.

[0031] The clutch driving gear 71 is drivingly connected to the worm gear 4. Specifically, a linkage gear one 17 is coaxially connected to the worm gear 4, and a linkage gear two 18 that meshes with it is rotatably arranged outside the linkage gear one 17. The linkage gear two 18 meshes with the clutch driving gear 71. The worm gear 4 can drive the clutch driving gear 71 to rotate through the linkage gear one 17 and the linkage gear two 18.

[0032] The clutch driven gear 72 is drivingly connected to the reduction gear set 8, and the linkage member 73 can make the transmission connection between the clutch driving gear 71 and the clutch driven gear 72 connected or disconnected.

[0033] Specifically, the clutch driving gear 71 is drivingly connected to the cam 731. The cam 731 can drive the clutch driven gear 72 to rotate through the linkage ball 733, and the control piece 732 can make the linkage ball 733 move away from the clutch driven gear 72.

[0034] The clutch driven gear 72 is provided with a linkage groove 9, and a groove 10 is formed on the end face of the clutch driven gear 72. The linkage groove 9 is formed on the side wall of the groove 10. The cam 731 is rotatably arranged in the groove 10, and the linkage ball 733 is movably arranged in the groove 10. A cover body 14 is detachably connected to the mounting bracket 13. The cover body 14 is used to cover the opening of the groove 10, thereby preventing the linkage ball 733 from disengaging from the groove 10 and ensuring the stability and reliability of the overall structure.

[0035] Specifically, when the cam 731 rotates, it can push the linkage ball 733 into and press it in the linkage groove 9. The linkage ball 733 is adapted to the linkage groove 9. At this time, through the cooperation of the linkage groove 9 and the linkage ball 733, the cam 731 can drive the clutch driven gear 72 to rotate through the linkage ball 733.

[0036] In this embodiment, there are two linkage grooves 9 which are arranged oppositely, and there are two linkage balls 733 which respectively correspond to the two linkage grooves 9, thereby ensuring that the cam 731 can stably drive the clutch driven gear 72 to rotate through the linkage balls 733.

[0037] The control piece 732 can make the linkage ball 733 disengage from the linkage groove 9. Specifically, the control piece 732 is made of a magnetically attractive metal. The control piece 732 is arranged on the cover body 14. The linkage ball 733 is made of a magnet. The linkage ball 733 can cooperate with the control piece 732 for magnetic attraction. It should be noted that through the cooperation of the control piece 732 and the linkage ball 733 for magnetic attraction, under the magnetic attraction effect, the linkage ball 733 disengages from the linkage groove 9 and adsorbs on the control piece 732. As another solution, the control piece 732 can be made of a magnet that is magnetically attracted to the linkage ball 733. After the linkage ball 733 disengages from the linkage groove 9 and adsorbs on the control piece 732, at this time, the cam 731 cannot drive the driven gear 72 to rotate, and the driven gear 72 can rotate independently.

[0038] A plurality of connection holes 15 are formed on the mounting bracket 13, and a plurality of hooks 16 are arranged on the mounting bracket 13. The hooks 16 have the ability of elastic deformation. The plurality of hooks 16 are respectively clamped in the plurality of connection holes 15. When disassembling, only by applying an external force to make the hooks 16 disengage from the connection holes 15, the mounting bracket 13 can be removed. The operation is simple and the disassembly is convenient and fast.

[0039] In the state of automatic window opening, the rotary drive source 2 drives the worm 5 to rotate at this time. The worm 5 drives the worm wheel 4 to rotate. The worm wheel 4 drives the clutch driving gear 71 to rotate through the first linkage gear 17 and the second linkage gear 18. The clutch driving gear 71 drives the cam 731 to rotate. The cam 731 presses the linkage ball 733 tightly in the corresponding linkage groove 9. The cam 731 drives the clutch driven gear 72 to rotate through the linkage ball 733. The clutch driven gear 72 drives the output shaft 6 to rotate through the reduction gear set 8. At this time, due to the cooperation between the worm 5 and the worm wheel 4, the window is locked and the user cannot manually open or close the window. When switching to the manual window opening state, the rotary drive source 2 rotates in reverse and drives the worm 5 to rotate. The worm 5 drives the worm wheel 4 to rotate. The worm wheel 4 drives the clutch driving gear 71 to rotate in reverse through the first linkage gear 17 and the second linkage gear 18. The clutch driving gear 71 drives the cam 731 to rotate in reverse. The cam 731 moves away from the linkage ball 733 and cannot press it tightly in the corresponding linkage groove 9. At this time, under the magnetic attraction between the control piece 732 and the linkage ball 733, the linkage ball 733 disengages from the linkage groove 9 and adsorbs on the control piece 732. At this time, the cam 731 cannot drive the driven gear 72 to rotate, and the clutch driven gear 72 can rotate independently.
