Referring to fig. 1, the present embodiment provides a transmission mechanism 100, which includes an output shaft 110, and a transmission assembly 120 and a calibration assembly 130 respectively connected to the output shaft 110, wherein the output shaft 110 is used to connect to a member to be driven, the calibration assembly 130 includes an adjusting assembly 132 connected to the output shaft 110, and an adjusting locking assembly 134 connected to the adjusting assembly 132, and the adjusting locking assembly 134 is used to adjust a state of the adjusting assembly 132, so as to determine a start angle and/or an end angle of rotation of the output shaft 110 through the adjusting assembly 132.
Specifically, in a possible embodiment of the present application, the driving member may be a door or a window, so that the door or the window can be driven to open or close by the rotation of the output shaft 110. It can be understood that, in the actual implementation process, not only can be limited to controlling the door and window, but also can be applied to other occasions where needs exist, and the embodiment of the application does not specifically limit the application. When the transmission mechanism 100 is applied to control the opening or closing of a door or a window, if the required opening or closing is realized only by forward rotation or reverse rotation of the output shaft 110, in an actual application process, the current opening angle of the door or the window may not be known, so that the rotation angle of the output shaft 110 cannot be precisely controlled to realize the corresponding opening or closing operation.
By connecting the transmission assembly 120 and the calibration assembly 130 with the output shaft 110 respectively, after the output shaft 110 is connected with a to-be-driven member, the position relation between the adjusting assemblies 132 is changed by adjusting the adjusting locking assembly 134 of the calibration assembly 130, after the adjustment is completed, the adjusted state of the adjusting assemblies 132 is locked, so that the rotation of the output shaft 110 is matched with the adjusting assemblies 132, and when the output shaft 110 rotates, the rotation angle of the output shaft 110 can be determined, so that the required precise control is realized. With the above form, the calibration component 130 only needs to be adjusted during the first installation, and the required control requirements can be realized without re-calibration and debugging in the subsequent control process.
The transmission mechanism 100 provided by the embodiment of the application can drive the output shaft 110 to realize forward rotation or reverse rotation through the output shaft 110, and the transmission assembly 120 and the calibration assembly 130 respectively connected with the output shaft 110, so that when the output shaft 110 is connected with a door or a window, a required control function can be realized through rotation of the output shaft 110. In addition, by connecting the calibration assembly 130 with the output shaft 110, the corresponding state of the adjustment assembly 132 can be adjusted according to the current position and rotation angle of the output shaft 110, and when the state of the adjustment assembly 132 is adjusted, the adjustment can be performed by adjusting the locking assembly 134, and the adjusted state is locked, so as to ensure the stability of the adjusted state. Wherein, after the adjustment assembly 132 completes the required adjustment, the starting angle and/or the ending angle of the rotation interval of the output shaft 110 can be determined by the adjustment assembly 132. Thus, in the installation process, the rotation starting position of the output shaft 110 can be conveniently set, so that the universality and the intelligence during use are improved.

Specifically, the limit switches 1327 spaced apart from each other on the circuit board 1326 are located on the same circumference, so that when the first adjustment gear 1322 rotates relative to the second adjustment gear 1324, interference between a boss 1328 provided on the first adjustment gear 1322 and the limit switch 1327 is avoided. In addition, the adjustment locking assembly 134 adjusts the rotation angle of the second adjustment gear 1324 to rotate the first adjustment gear 1322 relative to the second adjustment gear 1324, and after the adjustment is completed, the adjustment locking assembly 134 locks the second adjustment gear 1324 to prevent the second adjustment gear 1324 from rotating freely. At this time, when the output shaft 110 rotates to drive the first adjusting gear 1322 to rotate, the relative rotation amount of the second adjusting gear 1324 and the second adjusting gear 1324 can be realized through the matching between the boss 1328 and the limit switch 1327.
It should be noted that, in the embodiment of the present application, there is no specific limitation on the setting form of the limit switch 1327, for example, the limit switch 1327 may adopt a proximity switch, an optoelectronic switch or a hall switch, and when the hall switch is adopted, the boss 1328 needs to adopt a magnetic material to ensure the generation of a stable electrical signal. When the photoelectric switch is adopted, a grating type or a light sensation type can be adopted as long as the required requirements can be met. In addition, when controlling the opening and closing of the door and window, the rotation angle of the door and window is limited, and the first adjusting gear 1322 and the second adjusting gear 1324 can meet the required control requirement without rotating a whole circle, so that the first adjusting gear 1322 and the second adjusting gear 1324 can adopt all gears, and can also be flexibly set into sector gears according to the requirement, and the embodiment of the application does not specifically limit the requirement.

Wherein, the manual adjusting gear 1344 can be provided with an inner hexagonal blind hole, so that the manual adjusting gear 1344 can be driven to rotate by an inner hexagonal wrench. After the required adjustment requirement is completed, in order to ensure that the adjusted second adjustment gear 1324 is locked, so as to achieve the purpose of calibrating the relative position of the first adjustment gear 1322 and the second adjustment gear 1324, the locking member 1346 may lock the first dual gear 1342, thereby achieving the purpose of locking the second adjustment gear 1324.

In addition, the locking member 1346 is disposed in parallel with the adjustment lever 1344a, so that the locked position is also in a direction perpendicular to the rotation shaft 1342 a.
