Detailed Description
As shown in fig. 1 to 8, the present embodiment provides an automatic clutch device for a window opener, which, as shown in fig. 1, includes an upper cover 11 and a lower cover 12, and further includes a driving mechanism, a clutch structure and a motor 13, which are disposed between the upper cover 11 and the lower cover 12, the clutch structure includes an input portion, a connecting portion and an output portion, and the power of the motor 13 is sequentially transmitted to the input portion, the connecting portion and the output portion through the driving mechanism. The connecting portion is provided with a rotating mechanism rotatable with the lower cover 12. As shown in fig. 2, the clutch state of the clutch structure changes depending on the relative position between the rotation mechanism and the lower cover 12.
As shown in fig. 1, the driving mechanism is a worm 21 and a gear structure engaged with each other, and the gear is a helical gear 22.
As shown in fig. 1 and 3, the input portion, the connecting portion, and the output portion are all gear structures, and gears in the gear structures are connected with adjacent components through pin shafts. The first gear structure 141 at the input portion, the clutch gear structure at the connecting portion, and the second gear structure 142 at the output portion are engaged with each other and rotated by the driving mechanism.
Specifically, as shown in fig. 3 and 4, the clutch gear structure includes an upper clutch gear 1431, a lower clutch gear 1432, and a pinion gear 144 fixedly disposed on the rotating mechanism 161, the upper clutch gear 1431 is engaged with the first gear structure 141, and the pinion gear 144 is engaged with the lower clutch gear 1432 and the second gear structure 142, respectively.
As shown in fig. 3, one end of the cam structure 161 serving as the rotating mechanism is fixed in a hole 1213 provided in the lower cover 12 by a pin 154, and the pin 154 is rotatable in the hole 1213. The pinion 144 is disposed at the other end of the cam structure 161, a spring is disposed between the cam structure 161 and the pinion 144, and the pinion 144 can move up and down under the elastic force of the spring.
As shown in fig. 2 and 3, the lower cover 12 is further provided with a limiting mechanism for limiting the cam structure, and the limiting mechanism is a triangular structure. Specifically, when the cam 161 rotates clockwise along the pin 154, it contacts with the left edge of the triangular structure of the lower cover 121, i.e., rotates to the bottom, and when the cam 161 rotates counterclockwise along the pin 154, it contacts with the right edge of the triangular structure of the lower cover 121, i.e., rotates to the bottom.
As shown in fig. 4, in order to increase the reduction ratio, reduce the volume of the window opener, and improve the overall aesthetic appearance of the window, both the input part and the output part adopt a dual-gear structure, that is, the first gear structure 141 includes a first upper gear 1411 and a first lower gear 1412, the second gear 142 includes a second upper gear 1421 and a second lower gear 1422, the first upper gear 1411 is engaged with the helical gear 22, and the first lower gear 142 is engaged with the upper clutch gear 1431; the pinion gear 144 is engaged with the lower clutch gear 1432 and the second lower gear 1422, respectively.
In other embodiments, the input and output portions may employ non-duplicate gears, or one of the input and output portions may employ duplicate gears.
In a specific application, as shown in fig. 5, the window opener is powered on, the motor 13 rotates in a forward direction to drive the first gear 141, if the first gear 141 rotates counterclockwise, the clutch gear structure 143 engaged with the first gear 141 rotates clockwise, under the action of the elastic force of the spring 171, a friction force is generated between the pinion 144 and the end surface of the clutch gear structure 143, the friction force enables the cam 161 to integrally rotate along with the clutch gear structure 143 until the cam 161 contacts with the left edge of the triangular structure of the lower cover 121, and reaches a state shown in fig. 5, at this time, the pinion 144 engaged with the clutch gear structure 143 simultaneously engages with the second lower gear 1422 of the second gear 142, and an "a electric state" is reached.
Similarly, if the motor 13 rotates in the reverse direction, when the cam 161 rotates counterclockwise to the bottom along the pin 154, it contacts with the right edge of the triangular structure of the lower cover 121, as shown in fig. 6, and at this time, the clutch pinion 144 meshes with the lower gear 1422 of the second gear 142, and the "B-motor state" is achieved.
When the window opener is powered off, the window can be opened and closed in a manual mode, namely the second gear 142 is driven to rotate manually, at the moment, the second gear 142 is not meshed with any gear, the self-locking structure of the input part is integrally separated, the window opener can rotate manually at will, and almost no resistance exists. That is, when the rotation locus of the cam structure 161 is in the non-state a and the non-state B, the window opener reaches the "C manual state".
In order to further ensure the safety of the conversion between the electric operation and the manual operation, after the window opener is driven by the motor to work in place (the door and window is opened to the maximum position, the complete closing position and the middle electric stop position), the window opener rotates reversely for a plurality of circles, so that the pinion 144 is completely separated from the second gear 142.
The free switching between electric and manual operation eliminates the problems that the switching between manual operation and electric operation needs additional structures and operation steps, simplifies the structure of equipment, saves space, simplifies operation steps and saves cost.
In other embodiments, the external teeth of the upper clutch gear can be removed and directly used as the upper cover, the pinion is fixedly connected to the rotating mechanism through the pin shaft, the pinion is attached to the upper cover under the action of the elastic force of the spring arranged below the pinion, and the assembly formed by the cover plate and the lower gear can freely rotate along the pin shaft. The structure can save the processing cost of the upper cover, save materials and improve economic benefits.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
