[0033] like Figures 1 to 6 As shown, the present invention provides a window opener, which includes a housing 30, a driving mechanism 10, a transmission mechanism 20 and a clutch mechanism 40, wherein the driving mechanism 10 and the transmission mechanism 20 are both mounted on the housing 30. The driving mechanism 10 is used to output driving force to the transmission mechanism 20, and the transmission mechanism 20 is connected to the chain mechanism 60 to promote the window opening and closing movement through the chain mechanism 60. Preferably, the window opener also includes a control mechanism 70, which is mounted on the housing 30 and electrically connected to the driving mechanism 10 to control the operation of the driving mechanism 10.

[0034] The clutch mechanism 40 is disposed between the driving mechanism 10 and the transmission mechanism 20 , and at least a portion of the driving mechanism 10 slides relative to the housing 30 , so as to disconnect or connect the transmission path between the transmission mechanism 20 and the driving mechanism 10 through the clutch mechanism 40 .

[0035] At least part of the drive mechanism 10 achieves sliding, including two forms: partial sliding of the drive mechanism 10 and overall sliding of the drive mechanism 10; and a form in which the drive mechanism 10 and the clutch mechanism 40 move together as a whole. During the sliding process of the sliding part of the drive mechanism 10, the transmission path can be disconnected or connected. After the sliding part of the drive mechanism 10 disconnects the transmission path, the drive mechanism 10 disconnects the power transmission path between the transmission mechanism 20, which can not only avoid the disadvantages of gear meshing between the transmission mechanism 20, but also reduce the space size of the housing 30. The sliding of part of the drive mechanism 10 is combined with the clutch mechanism 40 to achieve on-off control. The sliding part of the drive mechanism 10 can adopt an automatic alignment structure to reduce the impact noise and the disadvantages of unsmooth sliding.

[0040] The bevel gear 42 is fixed at the mounting position on the housing 30 and is connected to the transmission mechanism 20. Optionally, the bevel gear 42 is meshed with the transmission mechanism 20. For example, the bevel gear 42 is meshed with the transmission mechanism 20 through a straight tooth structure, a helical tooth structure or a bevel tooth 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.

[0047] Mode 1: The motor 111 and the transmission assembly 112 are fixedly connected, and the transmission assembly 112 and the bevel gear 42 are movably plugged in for transmission. The motor 111 and the transmission assembly 112 are fixedly connected to form a sliding part in the drive mechanism 10, and the transmission assembly 112 outputs the power of the motor 111. When the bevel gear 42 and the output end of the transmission assembly 112 are plugged in, the transmission assembly 112 drives the bevel gear 42 to rotate. When the bevel gear 42 and the output end of the transmission assembly 112 are separated, the transmission assembly 112 cannot transmit power to the bevel gear 42.

[0048] The transmission assembly 112 and the bevel gear 42 are movably plug-in transmission.

Optionally, the transmission assembly 112 is provided with an output shaft, and the output shaft is provided with a transmission groove.

Optionally, the motor 111 and the transmission assembly 112 are connected by bevel gear transmission; or the motor 111 and the transmission assembly 112 are connected by spur gear transmission.

[0054] Based on the above embodiment, the transmission assembly 112 adopts at least one stage planetary gear transmission mechanism 1121. The planetary gear transmission mechanism 1121 can adopt one or more stages of planetary gear transmission mechanism 1121 to form speed and torque regulation. Preferably, the planetary gear transmission mechanism 1121 is set to one, two or three stages.

[0055] In one embodiment, the driving mechanism 10 further includes an elastic reset assembly 50 connected to the motor assembly 11, and the elastic reset assembly 50 applies an elastic preload force on the motor assembly 11 in the direction of the clutch mechanism 40. The elastic reset assembly 50 adopts an elastic structure so that the sliding part of the motor assembly 11 has a preload force that automatically resets the connected transmission path.

[0056] Preferably, the elastic reset assembly 50 is applied to the bevel gear 42 and the motor assembly 11 when they move as a whole, so as to keep the bevel gear 42 and the transmission mechanism 20 in close cooperation.

A support 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, which is 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, and the sensing component 44 is used to detect the sliding position of the drive mechanism 10. The sliding part of the drive mechanism 10 can trigger the sensing component 44, and the sensing component 44 is triggered after the drive mechanism 10 moves into place, and outputs an electrical signal corresponding to the triggering. After the drive mechanism 10 moves away from the sensing component 44, the sensing component 44 outputs an electrical signal corresponding to the distance.

[0061] The sensing component 44 may adopt a contact trigger structure, and the sliding part of the driving mechanism 10 moves to contact the sensing component to achieve contact triggering.

Specifically, the induction component 44 includes a Hall switch, and the sliding part of the driving mechanism 10 is installed with a magnetic part.

[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 plugged in. The transmission assembly 112 and the bevel gear 42 are configured as a complementary plug-in fitting structure. Preferably, the bevel gear 42 and the transmission assembly 112 are movably plugged in to maintain the plug-in tightness of the transmission assembly 112 and the bevel gear 42.

[0064] When the clutch assembly 41 and the transmission assembly 112 are flexibly matched; or, when the motor 111 and the clutch assembly 41 are flexibly matched, the clutch assembly 41 has an elastic preload force and a movable expansion amount toward the direction of the motor 111, so that the clutch assembly 41 can be tightly matched 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 elastically pushing the connecting shaft 412. The connecting shaft 412 is movably plugged 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 one 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 is transmission-connected to the bevel gear 42. Preferably, the connecting shaft 412 and the bevel gear 42 are connected by spline matching.

For example, the wall surface of the sliding space is partially recessed to form a spline groove structure, and the spline part of the connecting shaft 412 is connected to the sliding space and is limited to the range of the spline structure.

One end of the stopper 413 is slidably limited in the sliding hole 422, wherein the sliding hole 422 can accommodate the stopper 413 so that the stopper 413 can be installed from the sliding hole 422, and can also guide the stopper 413. The large end size of the stopper 413 is larger than the aperture of the through hole 424, so that the stopper 413 is limited in the sliding hole 422. Preferably, the depth of the sliding hole 422 is larger than the sliding length of the stopper 413, so that the stopper 413 is located in the sliding hole 422 and moves, and the range of movement of the stopper 413 limits the range of movement of the connecting shaft 412.

[0069] The stopper 413 is a T-shaped structure, and the large end of the stopper 413 slides 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 the maximum extended position, and the large end of the stopper 413 abuts against the positioning plate 423. When the connecting shaft 412 and the transmission assembly 112 are plugged and matched, the connecting shaft 412 is pushed by the output end of the transmission assembly 112 to overcome the elastic force of the movable spring 411 and retract into the transmission hole 421, and the large end of the stopper 413 is away from the positioning plate 423.
