For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] In the related art, there are various problems when installing smart door locks. For example, the models of the original lock bodies on the door bodies may be inconsistent, and not all lock bodies have compatible quick-lock models, resulting in many original lock bodies of door bodies not having universal quick-open smart locks. In response to the above problems, the embodiment of the present application provides a universal clutch device for door locks, which can connect the door handle and the lock core in a transmission manner, and the lock body can be unlocked when the handle is turned, which has smoother operation and more reliable performance.

[0052] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0053] Figure 2 is a schematic diagram of the external structure of a door lock universal clutch device according to an exemplary embodiment of the present application; Figure 4 yes Figure 2 Schematic diagram of the internal structure of the central door lock universal clutch device; Figure 2 and Figure 4 The external and internal structures of the door lock universal clutch device are shown respectively.

[0054] See also Figure 2 and Figure 4 The door lock universal clutch device provided in the present application includes a housing 1303, and a first end 1301 and a second end 1302 are arranged on opposite sides of the housing 1303, and the first end 1301 and the second end 1302 are connected by a transmission mechanism. The first end 1301 can be a power input end, and the second end 1302 can be a power output end. The first end 1301 is provided with a square shaft for being connected to the door lock handle by transmission, and the second end 1302 is provided with a rotating shaft for being connected to the lock cylinder of the door lock by transmission. A clutch mechanism is arranged between the first end 1301 and the transmission mechanism, and the clutch mechanism includes an active member connected to the first end and a driven member connected to the transmission mechanism. There is a clamping mechanism between the active member and the driven member, and the clamping mechanism is used to separate or engage the active member and the transmission member. When the transmission mechanism is driven by the door handle, the rotating shaft of the second end 1302 can be driven to rotate. Such an arrangement can connect the door handle 110 and the lock core 210 in a transmission manner. When the handle is turned, the lock body can be quickly unlocked, the operation is smoother, and the performance is more reliable.

[0055] Figure 1 This is a schematic diagram of the structure of the lock body in the related art, see Figure 1 In the related art, the lock body 200 has a square shaft hole 220 for connecting the handle and a lock core hole 230 for installing the lock core. The square shaft hole 220 and the lock core hole 230 are set at specific positions on the lock body 200, and there is a fixed distance L between the square shaft hole 220 and the lock core hole 230. When installing a quick-lock smart lock on the lock body 200, the smart lock needs to be consistent with the specifications of the lock body to be accurately installed. The specifications include the distance L. That is to say, in the quick-lock smart lock, the distance between the handle and the lock core must be consistent with the original mechanical lock body. However, in the related art, the distance L of the lock body is fixed, and the distance L on different lock bodies is not exactly the same. Therefore, many lock bodies cannot be installed with an adapted quick-lock smart lock.

[0056] Reference Figure 3The door lock universal clutch device 130 provided in the embodiment of the present application can be installed between the smart door lock panel 100 and the lock body 200. The handle 110 on the smart door lock panel 100 is connected to the first end 1301 of the door lock universal clutch device, and the second end 1302 is inserted into the lock core 210 of the lock body 200. After such a setting, when the handle 110 is turned, the lock core 210 can be indirectly rotated through the door lock universal clutch device 130 to achieve unlocking. The installation of the smart door lock will no longer be restricted by the distance L on the original lock body 200. It can be applied to different lock bodies, which can improve the versatility of the smart door lock.

[0057] Figure 5 yes Figure 4 A schematic diagram of the structure of the transmission mechanism of the central door lock universal clutch device; Figure 6 yes Figure 4 Schematic diagram of the coordination between the clutch mechanism and the transmission mechanism in the central door lock universal clutch device.

[0058] See also Figure 5 and Figure 6 In one implementation, the transmission mechanism includes a gear set, and the gear set includes a plurality of gears connected in transmission. The gear set can be configured as follows: when the first end 1301 rotates a preset angle, the number of rotations or angles of the second end 1302 is the number of rotations or angles of the lock core for unlocking. For example, when the first end 1301 rotates about 45 degrees (but not limited to 45 degrees, such as 20 degrees to 60 degrees), the angle of rotation of the second end 1302 is greater than the angle of rotation of the first end 1301, and the angle of rotation of the second end 1302 can be two and a half turns (but not limited to two and a half turns, such as 180 degrees to 280 degrees), and two and a half turns are generally the number of rotations of the lock core for unlocking. By rotating the handle about 45 degrees (but not limited to 45 degrees, such as 20 degrees to 60 degrees), the lock body that originally needs to control the lock core to rotate multiple turns to unlock can be directly unlocked, thereby improving the convenience of unlocking.

[0059] In one implementation, the gear set includes a first gear 1311, a second gear 1321, a third gear 1331 and a fourth gear 1341; the first end 1301 is used to drive the first gear 1311 to rotate, the first gear 1311 and the second gear 1321 are meshed, the second gear 1321 and the third gear 1331 are coaxially connected, the third gear 1331 and the fourth gear 1341 are meshed, and the fourth gear 1341 and the second end 1302 are coaxially connected.

[0060] In one implementation, the gear ratio of the first gear 1311 and the second gear 1321 is greater than the gear ratio of the third gear 1331 and the fourth gear 1341; the radius of the first gear 1311 is greater than the radius of the second gear 1321, the third gear 1331 and the fourth gear 1341 respectively; the radius of the third gear 1331 is greater than the radius of the second gear 1321 and the fourth gear 1341. Through such a configuration, when the first gear 1311 rotates about 45 degrees (for example, 90 degrees to 280 degrees), the fourth gear 1341 can be rotated two and a half turns (but not limited to two and a half turns, for example, 180 degrees to 280 degrees), thereby realizing that when the handle is rotated 45 degrees (but not limited to 45 degrees, for example, 90 degrees to 280 degrees), the second end 1302 can be rotated two and a half turns (but not limited to two and a half turns, for example, 180 degrees to 280 degrees). After such arrangement, the door lock universal clutch device of this embodiment can be better applied to the installation of quick-opening smart door locks. When installing the smart door lock, it will not be restricted by the distance between the square axis and the lock core of the original mechanical lock body. No hole is required in the door body, and the installation of the smart door lock is more convenient, so that the quick-opening smart door lock can be better popularized and applied.

[0061] Figure 8 is a structural schematic diagram of a clutch mechanism of a door lock universal clutch device according to an exemplary embodiment of the present application; Fig. 9 It is a schematic diagram of an engagement mechanism of a clutch mechanism of a door lock universal clutch device according to an exemplary embodiment of the present application.

[0062] See also Figure 8 and Fig. 9 In this embodiment, the rotating disk 1501 fixedly connected to the square shaft at the first end is configured as an active member, and the first gear of the transmission mechanism is configured as a driven member. The rotating disk 1501 and the first gear 1311 are connected by a clamping mechanism, and the clamping mechanism is used to clamp and position the rotating disk 1501 and the first gear 1311. The clamping mechanism includes a plug-in portion 1511 provided on the rotating disk 1501, and a plug-in component 1313 fixed on the first gear 1311, and the plug-in component 1313 is used to be plugged and matched with the plug-in portion 1511 along the circumference of the rotating disk 1501.

[0063] In one implementation, a fixing block is fixedly mounted on the first gear 1311, a mounting hole is formed on the fixing block, the connector 1313 is passed through the mounting hole and can be inserted into or extended from both ends of the mounting hole, the connector 1313 can be a columnar body, such as a cylindrical pin, or a component of other shapes that can cooperate with the plug-in portion 1511, and a reset spring can be provided in the mounting hole for installing the connector 1313, and the reset spring is used to enable the connector 1313 to reset in time after movement. The plug-in portion 1511 includes a plurality of plug-in holes arranged on the turntable 1501, and the plurality of plug-in holes are distributed in a circular array in the circumferential area of ​​the turntable 1501. The plug-in holes are used to be plugged and matched with the connector 1313. When the connector 1313 is inserted into the plug-in portion 1511 on the turntable 1501, the turntable 1501 and the first gear 1311 are engaged. When the square shaft drives the turntable 1501 to rotate, it can drive the first gear 1311 to rotate, thereby driving the transmission mechanism to operate.

[0064] When unlocked, the turntable 1501 connected to the square shaft and the first gear 1311 are in a separated state, and turning the door lock handle will not transmit the driving force to the gear set, and the rotating shaft of the second end 1302 cannot be driven by the gear set, and thus the door cannot be unlocked; when unlocked, the turntable 1501 connected to the square shaft and the first gear 1311 are in an engaged state, and turning the door handle can transmit the driving force to the gear set, and the rotating shaft of the second end 1302 is rotated by the gear set, and the number of rotations is the number of unlocking circles of the lock core, thereby achieving unlocking. After such a setting, the door lock universal clutch device of this embodiment can be better applied to the installation of quick-opening smart door locks. When installing the smart door lock, it will not be limited by the distance between the original mechanical lock body square shaft and the lock core, and the door body does not need to be opened. The installation of the smart door lock is more convenient, so that the quick-opening smart door lock can be better popularized and applied.

[0065] Figure 7 is a schematic structural diagram of a connecting plate of a door lock universal clutch device according to an exemplary embodiment of the present application. Figure 4 , Figure 5 , Figure 7 The matching relationship between the connecting plate and the transmission mechanism is shown.

[0066] See also Figure 4 , Figure 5 and Figure 7In this embodiment, the door lock universal clutch device of this embodiment includes a housing 1303, in which a connecting plate that can run in a preset direction is installed, and the shape of the connecting plate 1304 can be matched with the internal space of the housing 1303, so that the connecting plate 1304 can move vertically stably in the housing 1303. The end of the plug-in 1313 away from the plug-in portion 1511 is in transmission cooperation with the connecting plate 1304, and the connecting plate 1304 is driven by a driving device. The portion where the connecting plate 1304 and the plug-in are matched has an arc-shaped rib 1344 extending in a direction perpendicular to the plug-in 1313, and the arc-shaped rib 1344 extends in the rotation direction of the first gear 1311, and the end of the plug-in 1313 away from the plug-in portion 1511 is used to abut against the inner side of the arc-shaped rib 1344. One end of the connector 1313 extending out of the mounting hole elastically abuts against the inner side of the arc-shaped retaining edge 1344. When the connecting plate 1304 moves downward, the pin shaft can be pushed to move in the direction of the connector 1511. The arc-shaped retaining edge 1344 can push the connector 1313 and the connector 1511 to engage with each other, thereby achieving the engagement of the clutch mechanism.

[0067] In one implementation, the connecting plate 1304 is coupled to the driving module 1314 through a transmission member 1316. One end 1321A of the transmission member 1316 is fixed by a rotating shaft, and the other end 1312B is threadedly connected to the driving shaft 1315 of the driving module 1314. When the driving shaft 1315 rotates, it can drive the transmission member 1316 to rotate clockwise or counterclockwise around the rotating shaft. The middle part of the transmission member 1316 is supported on the connecting plate 1304 along the longitudinal direction.

[0068] When the operation of the connecting plate 1304 causes the arc-shaped retaining edge 1344 to move away from the connector 1313, the connecting plate 1304 is driven by the driving device; when the operation of the connecting plate 1304 causes the arc-shaped retaining edge 1344 to move close to the connector 1313, the connecting plate 1304 is driven by the reset elastic member, which may be a reset spring 1334 disposed between the connecting plate 1304 and the shell 1303. When the driving module 1314 drives the transmission member 1316 to rotate in the clockwise direction, the connecting plate 1304 can be driven to move upward, and the pressure of the arc-shaped retaining edge 1344 on the connector 1313 can be released. After the connector 1313 is reset, it will be disengaged from the connector part 1511, thereby realizing the separation of the clutch mechanism; when the driving module 1314 drives the transmission member 1316 to rotate in the counterclockwise direction, the connecting plate 1304 moves downward under the elastic force of the reset spring 1334, and pressure can be applied to the connector 1313, so that the connector 1313 and the connector part 1511 are engaged, thereby realizing the engagement of the clutch mechanism.

[0069] The door lock universal clutch device of the embodiment of the present application can be applied to the smart lock. When unlocking, after inputting the unlocking signal through password, fingerprint or other means, the driving module 1314 of the smart lock drives the transmission member 1316 to rotate in the counterclockwise direction, and the connecting plate 1304 automatically moves down under the elastic force of the reset spring 1334, thereby engaging the clutch mechanism. Then, when the handle is turned downward by 45 degrees (but not limited to 45 degrees, such as 90 degrees to 280 degrees), the rotating shaft of the second end 1302 can be driven to rotate through the transmission mechanism, thereby realizing quick unlocking. The door lock universal clutch device provided in the embodiment of the present application can be used in various mechanical lock bodies, with a more reliable structure and more labor-saving operation.

[0071] Please also see Figure 10-13 The door lock universal clutch device of this embodiment also includes a limit device, which is used to limit the rotation range of the turntable 1501. The limit device includes a limit plate 1401 coaxially fixedly connected to the turntable 1501; and includes a first limit member 1411 and a second limit member 1412 for limiting the limit plate 1401; the first limit member 1411 and the second limit member 1412 are used to limit the rotation range of the limit plate 1401 to a preset angle, and the preset angle can be 45-90 degrees, but is not limited thereto. In one implementation, the first limit member 1411 and the second limit member 1412 are used to limit the limit plate 1401 to a first rotation range or a second rotation range. When limited to the first rotation range, it is used to unlock or lock in the forward direction, and when limited to the second rotation range, it is used to unlock or lock in the reverse direction. The so-called forward unlocking or locking means that the door lock handle is set to the right, and the door can be unlocked by turning the handle clockwise, which is convenient for right-hand operation; the so-called reverse unlocking or locking means that the door lock handle is set to the left, and the door can be unlocked by turning the handle counterclockwise, which is convenient for left-hand operation. Through such a setting, the door lock universal clutch device provided in this embodiment can be set to operate in the forward direction or reverse direction according to the physiological characteristics, habits or installation characteristics of different groups of people, and has a wider range of applications.

[0072] In one implementation, a positioning structure is provided on the second position-limiting member 1412, and the positioning structure is used to limit the range of motion of the second position-limiting member 1412; or to switch the position-limiting plate 1401 to the first rotation range or the second rotation range. The positioning structure may include a positioning shaft 1416 fixedly arranged relative to the second position-limiting member 1412, and a positioning groove 1413 provided on the second position-limiting member 1412, and the positioning groove 1413 is sleeved on the positioning shaft 1416.

[0073] In this embodiment, the positioning shaft 1416 can limit the longitudinal movement range of the second limit member 1412, and the rotation range of the door lock handle is limited by limiting the limit plate 1401 to a preset rotation range. In one implementation, the limit plate 1401 is roughly elliptical, and the central axis of the limit plate 1401 and the square axis are coaxially arranged. The two sides of the shell 1303 are provided with limit grooves 1374 in the vertical direction, and the first limit member 1411 can be upwardly abutted against the slot 1364 of the connecting plate 1304 through the limit portion 1424; the second limit member 1412 can be pressed downwardly against the upper end of the reset spring in the limit groove 1374 through the limit portion 1414, and the lower end of the reset spring is supported on the lower groove wall 1354. The second limit member 1412 can move within the vertical length range defined by the limit groove 1374, thereby limiting the rotation range of the limit plate 1401 to the preset rotation range. In this embodiment, a reset spring is provided in the limit groove 1374. When the limit plate 1401 rotates and pushes the second limit member 1412 to move downward, the limit plate 1401 can be pushed to rotate and reset under the elastic force of the reset spring, thereby causing the door lock handle to rotate and reset.

[0074] The positioning structure can be used to switch the limit plate 1401 to the first rotation range or the second rotation range. If the door lock handle needs to be switched in the operating direction, the positioning shaft 1416 can be removed, and the position of the limit plate 1401 can be adjusted to another operating direction. Then, the positioning shaft 1416 can be re-inserted into the positioning groove 1413 and fixed. In this way, it can be switched to the reverse operating state. Similarly, if the door lock handle needs to be switched to another operating direction, the same operation is performed on the positioning shaft to adjust the position of the limit plate 1401.
