Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

Fig. 1 is a schematic diagram of an embodiment of the present invention. As shown in fig. 1, the window sash 1 rotates with the rotation structure 2. The transmission structure 3 is installed in the housing 4.

Fig. 2 is a top view of fig. 1. Fig. 3 is a cross-sectional view taken along line a-a of fig. 2. As shown in fig. 2 and 3, the transmission structure 3 is mounted in the housing 4. The transmission structure 3 is used for controlling the rotation of the rotating structure 2. The transmission structure 3 includes a motor 38 fixed to the bottom surface of the housing 4. A first gear 39 is fixed to an output shaft of the motor 38. The switch of the motor 38 may be disposed above the housing 4.

The transmission 3 further comprises a propeller shaft and a second gear 36. The first gear 39 meshes with the second gear 36. The second gear 36 is slidably secured to the drive shaft. Both ends of the transmission shaft are rotatably fixed on the bottom surface and the top surface of the shell 4 through bearing kits. Specifically, one end of the transmission shaft is fixed to the top surface of the housing 4 through the third bearing kit 31, and the other end of the transmission shaft is fixed to the bottom surface of the housing 4 through the fourth bearing kit 35. The bearing kit includes bearing inner race and bearing outer lane. A plurality of rotating balls are arranged between the bearing inner ring and the bearing outer ring. The bearing inner race is rotatable relative to the bearing outer race. The end face of the transmission shaft is fixed on the bearing inner ring, and the bearing outer ring is fixed on the shell 4.

A tie rod 37 is fixed to a gear surface of the second gear 36. The tie rod 37 passes through the bottom surface of the housing 4. Fig. 4 is a schematic view of the drive shaft and the second gear. Referring to fig. 4, the drive shaft includes a middle section 33 and upper and lower sections 32, 34 at opposite ends of the middle section 33. The periphery of the middle section 33 has a length of protruding teeth 30 parallel to the axial direction. A sliding hole is formed in the center of the second gear 36. One side of the sliding hole is provided with a concave groove corresponding to the convex tooth 30. The driving shaft passes through the sliding hole, and the protruding teeth 30 are inserted into the recessed grooves. The second gear 36 slides up and down the drive shaft within the confines of the projecting teeth 30. And the second gear 36 rotates to drive the transmission shaft to rotate.

Limiting structures (not shown) may be mounted at both ends of the protruding tooth 30, such as a disk having an area larger than that of the second gear 36, or other limiting structures. It is possible to limit the second gear 36 from slipping out while sliding within the range of the projecting tooth 30.

The rotating structure 2 comprises a rotating shaft 21 and a third gear 24. Both ends of the rotating shaft 21 are fixed by bearing sleeves. The window sash 1 is fixed to the rotation shaft 21. One end of the rotating shaft 21 is fixed to the top surface of the housing 4 by a first bearing kit 23. The other end of the rotating shaft 21 is fixed to a sill or a wall, or other suitable place, through a second bearing set 22. The bearing kit includes bearing inner race and bearing outer lane. A plurality of rotating balls are arranged between the bearing inner ring and the bearing outer ring. The bearing inner race is rotatable relative to the bearing outer race. The end face of the rotating shaft 21 is fixed to the inner race of the bearing, and the outer race of the bearing is fixed to a corresponding position. The third gear 24 is in mesh with the second gear 36.

Fig. 5 is a bottom view of fig. 1. As shown in fig. 5, an arc-shaped rotation opening 41 is formed in the bottom surface of the housing 4. When the second gear 36 rotates, the pull rod 37 protrudes out of the bottom surface of the housing 4 through the rotation opening 41 and rotates with the second gear 36. Since the window sash 1 does not rotate 360 degrees, the rotation opening 41 may have an arc shape.

The intelligently openable and closable window transmission works as follows:

pushing on the pull rod 37, the second gear 36 slides up the drive shaft until it meshes with the first gear 39 and the third gear 24. The motor 38 is operated, the first gear 39 rotates, the second gear 36 rotates, and the third gear 24 rotates. The rotation shaft 21 rotates. The window rotates. In the process, the transmission rod is also rotated due to the presence of the projecting tooth 30, but the transmission rod only plays a limiting role in controlling the position of the second gear 36. And because of the existence of the bearing sleeve, the rotating shaft 21 and the transmission shaft can rotate smoothly.

The pull rod 37 is pulled out and the second gear 36 slides down the drive shaft until it is disengaged from the first gear 39 and the third gear 24. The window is now out of the control of the motor 38 and can be opened and closed manually.

The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made without departing from the basic structure of the invention.
