DETAILED DESCRIPTION

[0024] Here, it should be noted that the functions and methods involved in the present invention are merely conventional adaptive applications of the prior art. Therefore, the improvement of the present invention on the prior art is essentially the connection relationship between the hardware, rather than the functions and methods themselves. That is, although the present invention involves some functions and methods, it does not include improvements to the functions and methods themselves. The description of the functions and methods in the present invention is to better illustrate the present invention so as to better understand the present invention.

[0025] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0026] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 andFigure 7 As shown, this embodiment provides a window opener clutch mechanism, which is installed in a housing 1 of the window opener, wherein a motor 2 and a chain 3 are arranged in the housing 1, and the output end of the motor 2 and the chain 3 are connected through a transmission mechanism 4. Specifically, a worm 21 is fixedly arranged at the output end of the motor 2, and a worm wheel 41 meshing with the worm 21 is arranged at the input end of the transmission mechanism 4.

[0028] The housing 1 is provided with a mounting seat 5 for mounting the motor 2. The top and bottom of the mounting seat 5 are connected to a mounting plate 6. The mounting seat 5 is rotatably connected to the mounting plate 6 via a rotating shaft 7. In this embodiment, the mounting seat 5 can rotate relative to the mounting plate 6 around the rotating shaft 7 under the action of an external force. During this process, the mounting seat 5 can be moved from the meshing position (reference Figure 1 and Figure 2 ) to the disengaged position (reference Figure 3 and Figure 4 ), when the mounting seat 5 is in the meshing position, the worm 21 at the output end of the motor 2 meshes with the worm wheel 41 at the input end of the transmission mechanism 4 for transmission. At this time, the motor 2 works and drives the chain 3 to extend or retract through the transmission mechanism 4 to realize the opening or closing of the window sash. When the mounting seat 5 is in the separation position, the worm 21 at the output end of the motor 3 and the worm wheel 41 at the input end of the transmission mechanism 4 are separated from each other, and the power of the motor 2 cannot be transmitted to the transmission mechanism 4. At this time, the window sash can be manually pushed open or closed without being affected by the self-locking ability of the motor 2, so as to manually control the opening or closing of the window in the power-off state. After the window is opened or closed, the mounting seat 5 is driven to rotate and reset to the previous meshing position. At this time, the worm wheel 41 and the worm 21 mesh and self-lock, which can maintain the state of the window sash.

[0029] Furthermore, the mounting seat 5 is connected with an operating part, and the operating part can drive the mounting seat 5 to rotate around the rotating shaft 7 from the meshing position to the disengaged position under the action of an external force. In this embodiment, the operating part is a push-pull member 8, and a push-pull opening 11 is provided on the housing 1, and the push-pull member 8 is movably arranged in the push-pull opening 11. Specifically, the push-pull member 8 includes a push-pull plate 81 and a push-pull rod 82, the push-pull plate 81 is located outside the housing 1, and the push-pull rod 82 extends into the inside of the housing 1 through the push-pull opening 11 and is connected and fixed to the mounting seat 5. In practice, the mounting seat 5 can be driven to rotate by forcing the push-pull plate 81.

[0030] For the convenience of operation, a shifting hole 811 is provided on the push-pull plate 81 so that a screwdriver can be used to shift the shifting hole 811 to drive the mounting seat 5 to rotate.

[0031] Of course, to adapt to more installation scenarios, in this embodiment, another operating part is provided on the mounting base 5. This operating part is an operating port 51 provided at the end of the mounting base 5, and a relief port 61 corresponding to the operating port 51 is provided on the mounting plate 6. A corresponding relief port is also provided on the housing 1. When needed, an operating rod can be inserted into the operating port 51 to apply an external force to the mounting base 5, driving the mounting base 5 to rotate. The relief ports on the housing 1 and the mounting plate 6 reserve sufficient space for the insertion and movement of the operating rod.

[0032] Further, to ensure that the mounting base 5 can remain in its meshing position without external force and ensure that the worm gear 41 and the worm 21 can remain meshed, a limiting structure is provided between the mounting base 5 and the mounting plate 6 in this embodiment. Then, without external force, the mounting base 5 can remain in its meshing position under the action of this limiting structure. Specifically, this limiting structure includes a limiting member 52 provided on the mounting base 5. The limiting member 52 is specifically a spring ejector pin, which includes a plug pin 521 and an elastic member (not shown in the figure). The part of the plug pin 521 extending out of the mounting base 5 is hemispherical. The above-mentioned limiting structure also includes a socket 62 provided on the mounting plate 6. When the mounting base 5 is in the meshing position, the plug pin 521 can be inserted into the socket 62 under the elastic force of the elastic member to limit the relative positions of the mounting base 5 and the mounting plate 6. When the operating part is driven by an external force to drive the mounting base 5 to rotate towards the separation position, the socket 62 applies a force to the plug pin 521, causing the plug pin 521 to disengage from the socket 62. At this time, the elastic member is compressed and stores energy. When the operating part is driven by an external force to drive the mounting base 5 to rotate to the meshing position, the plug pin 521 can be reinserted into the socket 62 under the elastic force of the elastic member, ensuring that the mounting base 5 can remain stable without crosstalk when there is no external force and ensuring normal transmission.

[0033] More specifically, a plurality of limit pins 53 are provided on the above-mentioned mounting base 5, and a limit groove 63 slidably matched with the limit pins 53 is provided on the mounting plate 6. The cooperation between the limit pins 53 and the limit groove 63 limits the maximum rotation angle of the mounting base 5. In this embodiment, the mounting base 5 can rotate up to 6°.

[0034] The window opener clutch mechanism of this embodiment enables the window opener to have a clutch function, thus facilitating the electric control of the opening or closing of the window sash in the powered state and the manual control of the opening or closing of the window sash in the powered-off state, making the use of the window opener more flexible and convenient.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
