For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] like Figures 1 to 6 As shown, the present invention provides a window opener, which includes a housing 30, a drive mechanism 10, a transmission mechanism 20, and a clutch mechanism 40. Both the drive mechanism 10 and the transmission mechanism 20 are mounted on the housing 30. The drive mechanism 10 outputs driving force to the transmission mechanism 20, which is connected to a chain mechanism 60 to drive the window opening and closing movement. Preferably, the window opener further includes a control mechanism 70, which is mounted on the housing 30 and electrically connected to the drive mechanism 10 to control its operation.

[0034] The clutch mechanism 40 is disposed between the drive mechanism 10 and the transmission mechanism 20. At least part of the drive mechanism 10 slides relative to the housing 30 to disconnect or connect the transmission path between the transmission mechanism 20 and the drive mechanism 10 through the clutch mechanism 40.

[0035] At least a portion of the drive mechanism 10 slides, including both partial and complete sliding; and the drive mechanism 10 and clutch mechanism 40 move together as a whole. During the sliding of the drive mechanism 10, the transmission path can be disconnected or connected. When the sliding portion of the drive mechanism 10 disconnects the transmission path, the drive mechanism 10 disconnects the power transmission path between itself and the transmission mechanism 20, avoiding the drawbacks of gear meshing between the transmission mechanisms 20 and reducing the spatial dimensions of the housing 30. The partial sliding of the drive mechanism 10, combined with the clutch mechanism 40, achieves on / off control. The sliding portion of the drive mechanism 10 can employ an automatic alignment structure to reduce impact noise and the drawbacks of uneven sliding.

[0036] In one embodiment, the drive mechanism 10 and the clutch mechanism 40 are connected as a whole and can move as a whole to disconnect or connect the transmission path between the clutch mechanism 40 and the transmission mechanism 20. For example, the clutch mechanism 40 includes a bevel gear 42, which is connected to the output end of the drive mechanism 10 to enable overall movement.

[0037] In one embodiment, a portion of the drive mechanism 10 slides; or, the drive mechanism 10 causes a portion of the clutch mechanism 40 to slide, thereby disconnecting or connecting the transmission path between the clutch mechanism 40 and the transmission mechanism 20.

[0038] The drive mechanism 10 causes a portion of the clutch mechanism 40 to slide, thereby disconnecting or connecting the transmission path between the clutch mechanism 40 and the drive mechanism 10. The drive mechanism 10 includes a motor assembly 11, which is the power output component, and the clutch mechanism 40 is connected to the motor assembly 11. The clutch mechanism 40 includes a bevel gear 42 and a clutch assembly 41. The bevel gear 42 meshes with the transmission mechanism 20, and the motor assembly 11 disconnects or connects the transmission path between the clutch assembly 41 and the bevel gear 42.

[0039] The bevel gear 42 and the transmission mechanism 20 can adopt a bevel gear meshing transmission structure. The motor assembly 11 is slidably connected along the housing 30 and engages with the clutch assembly 41 and the bevel gear 42. The housing 30 can limit the sliding area of ​​the motor assembly 11, thereby realizing the adjustment and limitation of the sliding position of the drive mechanism 10. The window opener can be operated manually.

[0040] The bevel gear 42 is fixed in its mounting position on the housing 30 and is connected to the transmission mechanism 20. Optionally, the bevel gear 42 and the transmission mechanism 20 are meshed together. For example, the bevel gear 42 and the transmission mechanism 20 are meshed together by a spur gear structure, a helical gear structure, or a bevel gear structure.

[0041] A portion of the drive mechanism 10 slides to disconnect or connect the transmission path between the clutch mechanism 40 and the drive mechanism 10. The drive mechanism 10 includes a motor assembly 11. The clutch mechanism 40 includes a bevel gear 42 rotatably mounted on the housing 30, and the bevel gear 42 is drive-connected to the transmission mechanism 20. By sliding at least a portion of the motor assembly 11 along the housing 30, the motor assembly 11 and the bevel gear 42 engage in a drive-connection, and the bevel gear 42 and the transmission mechanism 20 maintain a stable connection.

[0042] Optionally, the bevel gear 42 is provided with a protruding transmission column structure, which is directly connected to the motor assembly 11.

[0043] In one embodiment, the motor assembly 11 and the clutch assembly 41, and the clutch assembly 41 and the bevel gear 42, can be connected by a plug-in drive or a toothed drive, which makes the transmission method more flexible and can be applied to different housing 30 spaces and internal transmission scenarios.

[0044] The motor assembly 11 includes a motor 111, which is connected to the input end of the clutch assembly 41. The motor 111 drives the bevel gear 42 to rotate through the clutch assembly 41, thereby forming a direct drive mechanism. The overall installation space is small, simplifying the transmission structure.

[0045] The transmission mechanism 20 includes a reduction gear assembly, which is connected to the bevel gear 42. The reduction gear assembly can be a reduction mechanism composed of multiple gears of different sizes. The bevel gear 42 transmits the power output from the motor 111 to the reduction gear assembly. The reduction gear assembly adjusts the window opening speed through multi-stage reduction.

[0046] In a preferred embodiment, the motor assembly 11 further includes a transmission assembly 112, which is drive-connected to the motor 111. The transmission assembly 112 is located between the motor 111 and the clutch assembly 41, and regulates the speed and torque output by the motor 111. The drive-connection between the transmission assembly 112 and the motor 111 can be either a fixed connection or a movable connection.

[0047] In method one, the motor 111 and the transmission assembly 112 are fixedly connected, while the transmission assembly 112 and the bevel gear 42 are movably connected for transmission. The fixed connection of the motor 111 and the transmission assembly 112 forms a sliding portion within the drive mechanism 10, and the transmission assembly 112 outputs power from the motor 111. When the bevel gear 42 is connected to the output end of the transmission assembly 112, the transmission assembly 112 drives the bevel gear 42 to rotate. When the bevel gear 42 is separated from the output end of the transmission assembly 112, the transmission assembly 112 cannot transmit power to the bevel gear 42.

[0048] The transmission assembly 112 and the bevel gear 42 are movably connected for transmission. Optionally, the transmission assembly 112 is provided with an output shaft, which has a transmission surface. For example, the output shaft can be a chamfered shaft, a polygonal shaft, a splined shaft, or other shaft structures with a transmission surface. The bevel gear 42 is provided with an insertion groove. The output shaft and the insertion groove are engaged to form a power transmission, which not only enables automatic alignment but also reduces noise during the sliding process. Optionally, the transmission assembly 112 is provided with an output shaft, which has a transmission groove. The bevel gear 42 is slidably inserted into the transmission groove to form a plug-in transmission connection.

[0049] Method 2: The motor 111 and the transmission assembly 112 are movably connected, and the transmission assembly 112 is assembled with the bevel gear 42. The transmission assembly 112 and the motor 111 are movably connected for transmission or gear meshing. The motor 111 and the transmission assembly 112 are movably connected, with the motor 111 serving as the sliding part of the drive mechanism 10. The transmission assembly 112 is assembled with the bevel gear 42, and the transmission assembly 112 can adjust the speed and torque transmitted by the motor 111 through an internal transmission structure before outputting it, so that the bevel gear 42 rotates and drives the transmission mechanism 20.

[0050] like Figure 1 and Figure 2 As shown, optionally, the drive mechanism 10 further includes an elastic reset component 50 connected to the motor assembly 11. The elastic reset component 50 applies an elastic preload force to the motor assembly 11 in the direction of the clutch mechanism 40. The motor 111 and the transmission assembly 112 are movably connected. The elastic reset component 50 applies an elastic preload force to the motor 111 to satisfy the requirement that the motor 111 and the transmission assembly 112 can be movably separated or connected, and that they can have tight transmission when connected, thereby improving the tightness of the transmission engagement.

[0051] Preferably, a mounting plate is provided inside the housing 30, and a bevel gear 42 is rotatably mounted on one side of the mounting plate via a bearing 43. The gearbox assembly 112 is mounted on the other side of the mounting plate and is assembled and connected to the bevel gear 42. The motor 111 is slidably mounted on the housing 30, and a power transmission structure is provided at the mating part between the output shaft of the motor 111 and the gearbox assembly 112.

[0052] For example, the output shaft of the motor 111 is configured as a chamfered shaft, a polygonal shaft, a splined shaft, or other shaft structures with a transmission surface, and the mating part of the gearbox assembly 112 is provided with a corresponding groove structure, and the motor 111 and the gearbox assembly 112 are movably connected for transmission.

[0053] Alternatively, the output shaft of the motor 111 may be equipped with a gear structure, and the mating portion of the transmission assembly 112 may be equipped with a corresponding gear structure to form a gear transmission connection. Optionally, the motor 111 and the transmission assembly 112 may be connected by bevel gear transmission; or, the motor 111 and the transmission assembly 112 may be connected by spur gear transmission.

[0054] Based on the above embodiments, the transmission assembly 112 employs at least one stage of planetary gear transmission mechanism 1121. The planetary gear transmission mechanism 1121 may be a single-stage or multi-stage planetary gear transmission mechanism 1121 to achieve speed and torque regulation. Preferably, the planetary gear transmission mechanism 1121 is configured as a single-stage, two-stage, or three-stage transmission.

[0055] In one embodiment, the drive mechanism 10 further includes an elastic reset component 50 connected to the motor assembly 11, the elastic reset component 50 applying an elastic preload force on the motor assembly 11 toward the clutch mechanism 40. The elastic reset component 50 employs an elastic structure to provide an automatic reset preload force to the sliding portion of the motor assembly 11, connecting the drive path.

[0056] Preferably, the elastic reset component 50 is applied when the bevel gear 42 and the motor assembly 11 move as a whole to maintain a tight fit between the bevel gear 42 and the transmission mechanism 20. Alternatively, the elastic reset component 50 is applied when the motor 111 and the transmission assembly 11 are in relative movable fit to maintain a tight fit between the motor 111 and the transmission assembly 11.

[0057] Optionally, the elastic reset assembly 50 is an elastic element mounted on the housing 30. This elastic element can be a spring, torsion spring, elastic sheet, bellows, or other elastic structure or element. Furthermore, the sliding portion of the motor assembly 11 maintains a tight fit between the transmission parts under the elastic preload of the elastic reset assembly 50, improving the contact stability of the sliding fit.

[0058] The elastic reset component 50 is mounted on the housing 30 and elastically abuts against the motor assembly 11 to form an elastic reset structure. Preferably, the elastic reset component 50 elastically abuts against the tail end of the motor 111 to push the motor 111 and the components connected to the motor 111 to elastically reset.

[0059] In an optional embodiment, the elastic reset assembly 50 includes a reset spring that elastically abuts against the tail end of the motor 111. Further, the reset spring elastically abuts against the center of the motor 111 to provide balanced contact. Still further, the other end of the output shaft of the motor 111 extends beyond the tail end of the motor 111 to form a positioning post, and the reset spring is mounted on the housing 30 and sleeved on the positioning post to achieve center positioning. A support member is formed between the end of the reset spring and the end of the motor 111.

[0060] In one embodiment, the clutch mechanism 40 includes a sensing component 44 located in the sliding direction of the drive mechanism 10. The sensing component 44 and the transmission mechanism 20 are respectively located on both sides of the drive mechanism 10. The sensing component 44 is used to detect the sliding position of the drive mechanism 10. The sliding portion of the drive mechanism 10 can trigger the sensing component 44. The sensing component 44 is triggered after the drive mechanism 10 moves into position and outputs an electrical signal corresponding to the trigger. After the drive mechanism 10 moves away from the sensing component 44, the sensing component 44 outputs an electrical signal corresponding to the distance moved away.

[0061] The sensing component 44 can adopt a contact-triggered structure, whereby the sliding part of the drive mechanism 10 moves to contact the sensing component, thereby achieving contact triggering. For example, the sensing component 44 may be a limit switch; specifically, the sensing component 44 includes a micro switch 441.

[0062] The sensing component 44 can adopt an inductive triggering structure. The triggering part is installed on the sliding part of the drive mechanism 10. The sensing component 44 is located in the moving area of ​​the triggering part and does not directly contact it, thus realizing inductive triggering. For example, the sensing component 44 can be a Hall component, a photoelectric switch component, or an iron sensor. Specifically, the sensing component 44 includes a Hall switch, and a magnetic component is installed on the sliding part of the drive mechanism 10.

[0063] like Figure 3 and Figure 6 As shown, in one embodiment, the bevel gear 42 is rotatably mounted on the housing 30, and the transmission assembly 112 and the bevel gear 42 are movably engaged. The transmission assembly 112 and the bevel gear 42 are configured with a complementary engagement structure. Preferably, the bevel gear 42 and the transmission assembly 112 are movably engaged to maintain a tight engagement between the transmission assembly 112 and the bevel gear 42.

[0064] When the clutch assembly 41 and the transmission assembly 112 are in a movable engagement; or when the motor 111 and the clutch assembly 41 are in a movable engagement, the clutch assembly 41 has an elastic preload and a movable extension in the direction of the motor 111, so that the clutch assembly 41 can tightly engage with the motor assembly 11.

[0065] In one embodiment, the clutch assembly 41 includes a connecting shaft 412 slidably connected to the bevel gear 42 and a movable spring 411 that elastically pushes against the connecting shaft 412. The connecting shaft 412 is movably inserted into the output end of the motor assembly 11, and the movable spring 411 applies an elastic preload force on the connecting shaft 412 toward the side of the motor assembly 11.

[0066] A concave sliding space is provided at the center of the bevel gear 42, and the connecting shaft 412 is slidably connected to the sliding space and drivingly connected to the bevel gear 42. Preferably, the connecting shaft 412 and the bevel gear 42 are connected by a spline fit. The bevel gear 42 is provided with a limiting mechanism within the sliding space to limit the maximum sliding distance and maximum compression distance of the connecting shaft 412, so that the connecting shaft 412 is slidably limited to the bevel gear 42. For example, the wall of the sliding space is partially recessed to form a spline groove structure, and the spline portion of the connecting shaft 412 is connected to the sliding space and limited by the range of the spline structure.

[0067] In a preferred embodiment, the bevel gear 42 is provided with a sliding hole 422 and a transmission hole 421 connected to the sliding hole 422. A positioning plate 423 is provided between the sliding hole 422 and the transmission hole 421. The sliding hole 422 and the transmission hole 421 are recessed spaces on both sides of the positioning plate 423. A through hole 424 is provided on the positioning plate 423. The connecting shaft 412 is slidably connected to the transmission hole 421. A recessed spline groove structure is provided on the hole wall of the transmission hole 421. The connecting shaft 412 and the transmission hole 421 are inserted and slidably fitted.

[0068] The clutch assembly 41 includes a limiting member 413, which extends through a through hole 424 in a positioning plate 423 and connects to a connecting shaft 412. A movable spring 411 is positioned between the positioning plate 423 and the connecting shaft 412. One end of the limiting member 413 is slidably confined within a sliding hole 422, which both accommodates the limiting member 413 for installation and guides it. The larger end of the limiting member 413 is larger than the diameter of the through hole 424, thus confining the limiting member 413 within the sliding hole 422. Preferably, the depth of the sliding hole 422 is greater than the sliding length of the limiting member 413, allowing the limiting member 413 to move within the sliding hole 422, and the range of motion of the limiting member 413 limits the range of motion of the connecting shaft 412.

[0069] The limiting member 413 has a T-shaped structure, with its large end sliding in the sliding hole 422. When the connecting shaft 412 and the transmission assembly 112 are separated, the movable spring 411 pushes the connecting shaft 412 to its maximum extended position, and the large end of the limiting member 413 abuts against the positioning plate 423. When the connecting shaft 412 and the transmission assembly 112 are engaged, the connecting shaft 412, pushed by the output end of the transmission assembly 112, overcomes the elastic force of the movable spring 411 and retracts into the transmission hole 421, and the large end of the limiting member 413 moves away from the positioning plate 423.

[0070] Based on the above embodiments, the drive mechanism 10 further includes a lever assembly 12 slidably mounted on the housing 30. Part of the lever assembly 12 extends into the housing 30 and is connected to the drive mechanism 10. The lever assembly 12 located outside the housing 30 is pushed by an external force to slide at least part of the drive mechanism 10 along the housing 30.

[0071] The toggle assembly 12 slides on the outer surface of the housing 30. An operator can push the toggle assembly 12, thereby causing at least part of the drive mechanism 10 to slide, so as to switch between the disengaged position and the driven position. The toggle assembly 12 is connected to the motor 111 or the gearbox assembly 112 to drive the motor assembly 11 to slide.

[0072] Preferably, the drive mechanism 10 includes a connecting seat 113 located between the motor 111 and the gearbox assembly 112, and the toggle assembly 12 is connected to the connecting seat 113, thereby driving the motor assembly 11 to slide, which facilitates connection and movement.

[0073] Preferably, the toggle assembly 12 includes a toggle block 121 located outside the housing 30 and a toggle rod 122 inserted into the housing 30. The toggle rod 122 is connected to the connecting seat 113, thereby realizing translational sliding. The housing 30 has a guide hole 31, and the toggle rod 122 passes through the guide hole 31, exits the housing 30, and slides along the length direction of the guide hole 31.

[0074] Further, preferably, deformation holes are provided on both sides of the guide hole 31, and deformation ribs are formed between the deformation holes and the long sidewalls of the guide hole 31. A blocking protrusion protrudes from the middle of the two opposing long sidewalls of the guide hole 31. When the actuating rod 122 moves along the guide hole 31, the blocking protrusion generates a damping force on the actuating rod 122, and the deformation ribs elastically bend towards the deformation holes. This improves the stability of the actuating rod 122 in both the disengaged and driven positions, and also improves the tactile feel of manual operation. Preferably, the blocking protrusion is configured as a trapezoidal protrusion, a triangular protrusion, or an arc-shaped protrusion.

[0075] Other embodiments of the invention will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
