Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0029] Accordingly, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.

[0030] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0031] In the description of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this application is customarily placed when in use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. In addition, terms such as "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present application, it should also be noted that unless otherwise clearly specified and defined, the terms "arrangement", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0033] Please refer to Figure 1 , this embodiment provides a transmission mechanism 100, including an output shaft 110, and a transmission assembly 120 and a calibration assembly 130 respectively connected to the output shaft 110. The output shaft 110 is used to connect with a component to be driven. The calibration assembly 130 includes an adjustment assembly 132 connected to the output shaft 110, and an adjustment locking assembly 134 connected to the adjustment assembly 132. The adjustment locking assembly 134 is used to adjust the state of the adjustment assembly 132 to determine the starting angle and / or the ending angle of the rotation of the output shaft 110 through the adjustment assembly 132.

[0034] Specifically, in a feasible embodiment of the present application, the component to be driven can be a door or a window, and the rotation of the output shaft 110 is used to drive the door or window to open or close. It can be understood that in the actual implementation process, it is not limited to controlling doors and windows only, and it can also be applied to other occasions where there is a need. The embodiments of the present application do not make specific restrictions on this. When the transmission mechanism 100 is applied to the control of the opening or closing of a door or window, if the required opening or closing is only achieved by the forward or reverse rotation of the output shaft 110, in the actual application process, it may be impossible to accurately control the rotation angle of the output shaft 110 to achieve the corresponding opening or closing operation because the current opening angle of the door or window cannot be known.

[0035] By connecting the transmission component 120 and the calibration component 130 to the output shaft 110 respectively, after connecting the output shaft 110 to the component to be driven, by adjusting the adjustment and locking component 134 of the calibration component 130 to change the positional relationship between the adjustment components 132, after the above adjustment is completed, the adjusted state of the adjustment component 132 is locked, so as to achieve the matching of the rotation of the output shaft 110 and the adjustment component 132. When the output shaft 110 rotates, the rotation angle of the output shaft 110 can be determined, so as to facilitate the realization of the required precise control. In the above form, only the calibration component 130 needs to be adjusted during the first installation, and the required control requirements can be achieved without re-calibration and debugging during the subsequent control process.

[0036] The transmission mechanism 100 provided by the embodiments of the present application, through the output shaft 110, and the transmission component 120 and the calibration component 130 respectively connected to the output shaft 110, can drive the output shaft 110 to rotate forward or reverse through the transmission component 120. When the output shaft 110 is connected to a door or a window, it is convenient to achieve the required control function through the rotation of the output shaft 110. In addition, by connecting the calibration component 130 to the output shaft 110, the corresponding state of the adjustment component 132 can be adjusted according to the current position rotation angle of the output shaft 110. When adjusting the state of the adjustment component 132, it can be adjusted through the adjustment and locking component 134, and the adjusted state is locked to ensure the stability of the adjusted state. Among them, after the adjustment component 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 through the adjustment component 132. In this way, during the installation process, it is convenient to set the starting position of the rotation of the output shaft 110, so as to improve the versatility and intelligence during use.

[0037] Such as Figure 2 and Figure 3As shown in the figure, the adjusting component 132 includes a first adjusting gear 1322 and a second adjusting gear 1324 that are coaxially rotatably arranged. A circuit board 1326 is arranged on one side of the second adjusting gear 1324 facing the first adjusting gear 1322. Limit switches 1327 are arranged at intervals on the circuit board 1326. A boss 1328 is arranged on one side of the first adjusting gear 1322 facing the second adjusting gear 1324. The first adjusting gear 1322 is connected to the output shaft 110, and the second adjusting gear 1324 is connected to the adjusting and locking component 134. The adjusting and locking component 134 is used to adjust and lock the relative positions of the first adjusting gear 1322 and the second adjusting gear 1324 so that when the output shaft 110 is at the starting angle, the boss 1328 corresponds to one of the limit switches 1327.

[0038] Specifically, the limit switches 1327 arranged at intervals on the circuit board 1326 are located on the same circumference. In this way, when the first adjusting gear 1322 rotates relative to the second adjusting gear 1324, interference between the boss 1328 arranged on the first adjusting gear 1322 and the limit switches 1327 is avoided. In addition, the rotation angle of the second adjusting gear 1324 is adjusted through the adjusting and locking component 134 so that the first adjusting gear 1322 rotates relative to the second adjusting gear 1324. After the above adjustment is completed, the adjusting and locking component 134 locks the second adjusting gear 1324 to prevent the second adjusting gear 1324 from rotating randomly. At this time, when the output shaft 110 rotates to drive the first adjusting gear 1322 to rotate, the relative rotation amount between the second adjusting gear 1324 and the second adjusting gear 1324 can be realized through the cooperation between the boss 1328 and the limit switches 1327.

[0039] It should be noted that the embodiment of the present application does not specifically limit the setting form of the limit switches 1327. For example, the limit switches 1327 can adopt proximity switches, photoelectric switches or Hall switches, etc. When adopting a Hall switch, the boss 1328 needs to adopt a magnetic material to ensure the generation of stable electrical signals. When adopting a photoelectric switch, a grating type or a light sensing type can be adopted as long as the required requirements can be met. In addition, when controlling the opening and closing of doors and windows, the rotation angle of the doors and windows is limited, and the first adjusting gear 1322 and the second adjusting gear 1324 do not need to rotate a full circle to achieve the required control requirements. Therefore, the first adjusting gear 1322 and the second adjusting gear 1324 can adopt full gears or can be flexibly set as sector gears according to needs. The embodiment of the present application does not specifically limit this.

[0040] Such as Figure 2 and Figure 3As shown in the figure, the adjustment and locking assembly 134 includes a first double gear 1342 meshing with the second adjustment gear 1324, and a manual adjustment gear 1344 meshing with the first double gear 1342. The adjustment and locking assembly 134 further includes a locking member 1346 cooperating with the first double gear 1342, and the locking member 1346 is used to lock the relative positions of the first adjustment gear 1322 and the second adjustment gear 1324.

[0041] Specifically, when the manual adjustment gear 1344 rotates, it drives the first double gear 1342 to rotate, and the first double gear 1342 then drives the second adjustment gear 1324 to rotate, so as to achieve the purpose of changing the relative positions of the first adjustment gear 1322 and the second adjustment gear 1324. Among them, an internal hexagon blind hole can be provided on the manual adjustment gear 1344 to facilitate driving the manual adjustment gear 1344 to rotate by using an internal hexagon wrench. After completing the required adjustment requirements, in order to ensure the locking of the adjusted second adjustment gear 1324 to achieve the purpose of calibrating the relative positions of the first adjustment gear 1322 and the second adjustment gear 1324, the locking member 1346 can lock the first double gear 1342, and further achieve the purpose of locking the second adjustment gear 1324.

[0042] As Figure 2 shown, in an alternative embodiment of the present application, the manual adjustment gear 1344 includes an adjustment rod 1344a arranged parallel to the rotating shaft 1342a of the first double gear 1342, and a third adjustment gear 1344b arranged on the adjustment rod 1344a. The locking member 1346 is a locking screw arranged parallel to the adjustment rod 1344a, and the locking screw is used to abut against the side surface of the first double gear 1342.

[0043] In the above manner, the positions of adjustment and locking are in the direction parallel to the rotating shaft 1342a, and the required adjustment operations are completed in the form of manually adjusting the locking member 1346 and the adjustment rod 1344a.

[0044] As Figure 3 described, in another alternative embodiment of the present application, the manual adjustment gear 1344 includes an adjustment rod 1344a arranged perpendicular to the rotating shaft 1342a of the first double gear 1342, and a third adjustment gear 1344b arranged on the adjustment rod 1344a. The locking member 1346 is a locking screw arranged parallel to the adjustment rod 1344a, and a damping block 1348 is arranged on the rotating shaft 1342a, and the locking screw is used to abut against the side surface of the damping block 1348.

[0045] Specifically, by vertically arranging the adjusting rod 1344a and the rotating shaft 1342a, a worm and worm gear transmission form is formed between the third adjusting gear 1344b and the first double gear 1342, so that the adjusted position is in the direction perpendicular to the rotating shaft 1342a. In addition, by arranging the locking member 1346 parallel to the adjusting rod 1344a, the locked position is also in the direction perpendicular to the rotating shaft 1342a. With the above form, in actual applications, it can better adapt to the actual installation conditions, so as to facilitate the adjustment and calibration through the locking assembly 134.

[0046] As Figure 1 shown in the figure, the transmission assembly 120 includes a motor 122 and a gear set 126 connected to the motor 122 through a clutch assembly 124. An output gear 112 is arranged on the output shaft 110, and the gear set 126 is connected to the output shaft 110 through the output gear 112.

[0047] Specifically, by connecting the motor 122 and the gear set 126 through the clutch assembly 124, the gear set 126 can be driven to rotate forward or reversely as the output according to different states of the clutch assembly 124, or the connection between the motor 122 and the gear set 126 can be cut off according to actual needs. With the above form, when a fault occurs, it can avoid jamming inside, which is beneficial to the manual opening or closing of the doors and windows. Among them, the output gear 112 arranged on the output shaft 110 is connected to the gear set 126 to realize the transmission of torque to the output shaft 110. In addition, the output gear 112 is also meshed with the first adjusting gear 1322, and the first adjusting gear 1322 can be driven to rotate synchronously while the output shaft 110 rotates.

[0048] As Figure 1 shown in the figure, in an alternative embodiment of the present application, the gear set 126 includes a plurality of transmission gears arranged in a straight line in sequence, and adjacent transmission gears are meshed with each other. The transmission gears include spur gears and / or double gears.

[0049] Specifically, with the above form, the whole transmission can be arranged in a strip shape, avoiding affecting the actual installation due to being too wide as a whole. In addition, by setting the gear set 126 as a combination of spur gears and double gears, the required transmission relationship can be better matched, ensuring the reliability of the transmission.

[0050] As Figure 1 、 Figure 4 and Figure 5As shown, the clutch assembly 124 includes a manually operated clutch assembly 128 and an automatic clutch assembly 129 which are connected to each other. An input gear 1222 is provided at the output end of the motor 122, and a second double gear 123 which meshes with the input gear 1222. The second double gear 123 is connected to the manually operated clutch assembly 128, and the automatic clutch assembly 129 is connected to the gear set 126.

[0051] Specifically, in order to improve the structural compactness, a worm and worm gear arrangement form can be formed between the input gear 1222 and the second double gear 123. While changing the rotation direction, the overall compactness is achieved, which is beneficial to the realization of miniaturization. By connecting the second double gear 123 to the manually operated clutch assembly 128, the required connection can be established through the manually operated clutch assembly 128, and the connection can also be cut off according to actual needs to avoid jamming and prevent the opening and closing of the doors and windows, which is beneficial to improving the safety and reliability during use.

[0052] As Figure 4 and Figure 5 As shown, the manually operated clutch assembly 128 includes a holding member 1282 and a connecting shaft 1284 provided on the housing, and a third double gear 1285 which is slidably connected to the connecting shaft 1284. A button 1286 is provided on the holding member 1282. A first elastic member 1287 is provided between the button 1286 and the housing, and a second elastic member 1288 is provided between the third double gear 1285 and the housing. Pressing the button 1286 drives the holding member 1282 to hold the third double gear 1285, so that the third double gear 1285 is disengaged from the automatic clutch assembly 129.

[0053] Specifically, the connecting shaft 1284 is arranged parallel to the axis of the second double gear 123. In the default state, the third double gear 1285 is under the action of the second elastic member 1288 and is respectively connected to the first double gear 1342 and the automatic clutch assembly 129. When the button 1286 is subjected to a pressing force, the first elastic member 1287 is compressed. When the button 1286 approaches the third double gear 1285, the holding member 1282 and the button 1286 move synchronously, so that the button 1286 applies a force to the third double gear 1285 through the holding member 1282, overcoming the force of the second elastic member 1288, causing the third double gear 1285 to slide along the connecting shaft 1284, and thus disengaging from the connection with the automatic clutch assembly 129. When the force on the button 1286 is no longer applied, under the action of the first elastic member 1287 and the second elastic member 1288, the button 1286 and the third double gear 1285 can be respectively reset to the default connection state.

[0054] It should be noted that the embodiment of the present application does not specifically limit the setting form between the button 1286 and the housing. For example, the width of the button 1286 can be greater than the width of the housing (i.e., the structural form in Figure 4 ), and the housing can be used to limit the button 1286 so that the button 1286 slides linearly. The width of the button 1286 can also be set to be less than the width of the housing (i.e., the structural form in Figure 5 ). At this time, a guide block 1289 can be arranged in the housing to enable the button 1286 to slide linearly, or the internal structure of the housing can be directly utilized to achieve the linear sliding of the button 1286, which can be flexibly set according to actual needs.

[0055] As Figure 4 shown, the automatic clutch assembly 129 includes a fourth double gear 1292 and an arm support 1294 coaxially arranged with the fourth double gear 1292. The opposite ends of the arm support 1294 are respectively provided with a first clutch gear 1295 and a second clutch gear 1296. The fourth double gear 1292 includes a first gear 1292a and a second gear 1292b arranged in a stacked manner. The first clutch gear 1295 and the second clutch gear 1296 are respectively engaged with the second gear 1292b. When the second gear 1292b rotates, it drives the arm to rotate and enables the first clutch gear 1295 or the second clutch gear 1296 to be connected to the gear set 126.

[0056] Specifically, the fourth double gear 1292 is connected or disengaged from the third double gear 1285. When in the connected state, when the first gear 1292a and the second gear 1292b of the fourth double gear 1292 rotate synchronously, they drive the first clutch gear 1295 and the second clutch gear 1296 to rotate synchronously, and the arm support 1294 rotates relative to the fourth double gear 1292 so that the first clutch gear 1295 or the second clutch gear 1296 is connected to the gear set 126. Whether the first clutch gear 1295 is connected to the gear set 126 or the second clutch gear 1296 is connected to the gear set 126 is related to the rotation direction of the fourth double gear 1292, and the arm support 1294 has a tendency to rotate in the direction following the rotation of the fourth double gear 1292. In this way, when the driving direction of the motor 122 changes, it can be realized that the automatic clutch assembly 129 is separated briefly and then connected again while changing the transmission direction.

[0057] As Figure 6 and Figure 7As shown in the figure, the embodiment of the present application also discloses a door and window switch device 200, which includes a housing 210, a controller disposed in the housing 210, and the transmission mechanism 100 in the foregoing embodiment. The transmission mechanism 100 is disposed in the housing 210, and the controller is connected to the transmission mechanism 100. The door and window switch device 200 has the same structure and beneficial effects as the transmission mechanism 100 in the foregoing embodiment. The structure and beneficial effects of the transmission mechanism 100 have been described in detail in the foregoing embodiment and will not be repeated here.

[0058] It should be noted that the controller is connected to the motor 122 of the transmission mechanism 100, and the final driving function is achieved by controlling the rotation of the motor 122. In addition, the output shaft 110 and the button 1286 can be arranged on the same side of the housing 210 or on opposite sides, and can be flexibly arranged according to actual needs.

[0059] The foregoing are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
