Description

Technical Field

[0001] The present application relates to the technical field of door locks, and in particular to a universal door lock clutch device and an intelligent door lock. Background Art

[0002] Door locks are a type of equipment that can serve as insurance and safety precautions. With the development of science and technology and people's emphasis on residential safety, smart door locks are becoming more and more popular because they are more intelligent in terms of user identification, security, and manageability.

[0003] In the related art, there are various problems when installing smart door locks. For example, the model of the original lock body on the door body may be inconsistent. Not all lock bodies have an adapted quick lock model, resulting in many doors having original lock bodies without universal quick-open smart locks. When replacing the door lock, it is necessary to replace the original lock body together, or to re-drill holes in the door body. The door lock installation cost is high, the installation is cumbersome, and it is generally difficult for non-professionals to complete. Due to the above problems, the quick-open smart locks in the related art cannot be widely used. Summary of the invention

[0021] The technical solution provided by the embodiments of the present application may have the following beneficial effects:

[0022] The universal door lock clutch device provided in this embodiment includes a first end and a second end; the first end and the second end are connected by a transmission mechanism, and the second end is used to be connected to the lock core of the door lock by transmission; the transmission mechanism includes a gear set; the gear set includes a first gear, a second gear, a third gear and a fourth gear; the first end is used to drive the first gear to rotate, the first gear and the second gear are meshed, the second gear and the third gear are coaxially connected, the third gear and the fourth gear are meshed, and the fourth gear is coaxially connected to the second end.

[0041] The present application provides a universal door lock clutch device, which can improve the adaptability of the door lock and is more convenient to install.

[0042] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0043] Please also see Figures 2 to 7The universal door lock clutch device 130 provided in the present application includes a housing 1303, and the housing 1303 is provided with a first end 1301 and a second end 1302 on opposite sides. The first end 1301 can be a power input end, and the second end 1302 can be a power output end, which is used to be connected to the lock cylinder of the door lock. A transmission mechanism is provided in the housing 1303, and the first end 1301 and the second end 1302 are connected to each other through the transmission mechanism; the transmission mechanism includes a gear set; the gear set includes a first gear 1311, a second gear 1321 ( Figure 7 ), the third gear 1331 and the fourth gear 1341. A rotating shaft can be set at the first end 1301, and the rotating shaft can be a square shaft or a rotating shaft of other shapes that is detachably connected to the door handle. The rotating shaft at the first end is connected to the first gear 1311 in a transmission manner. When the door handle is turned, the first gear 1311 can be driven to rotate. The first gear 1311 is meshed with the second gear 1321, the second gear 1321 and the third gear 1331 are coaxially connected, the third gear 1331 and the fourth gear 1341 are meshed, the fourth gear 1341 is coaxially connected to the second end 1302, the second end 1302 includes a rotating shaft for connecting to the lock core, and the fourth gear 1341 is coaxially arranged with the rotating shaft of the second end 1302. When the first gear 1311 is driven by the door handle, the first gear 1311 will drive the second gear 1321, the third gear 1331 and the fourth gear 1341 to rotate synchronously, thereby driving the rotating shaft of the second end 1302 to rotate. This arrangement 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.

[0044] Figure 1 It is a schematic diagram of the structure of the lock body in the related art, referring to 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.

[0045] Reference Figure 2 and Figure 3The 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 universal door lock 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 by the 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.

[0046] Continue to refer to Figures 4 to 7 , the universal clutch device provided in the embodiment of the present application, in order to realize unlocking through the lock core when turning the door handle, the gear set can be configured as follows: when the first end 1301 rotates a preset angle, the number of rotations of the second end 1302 is the number of rotations of the lock core to unlock. For example, when the first end 1301 rotates about 45 degrees (but not limited to 45 degrees, such as 45 degrees-90 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 45 degrees-150 degrees), and two and a half turns are generally the number of rotations of the lock core to unlock. By turning the handle about 45 degrees (but not limited to 45 degrees, such as 45 degrees-90 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.

[0047] In one implementation, the first gear 1311 may be a sector gear, the second gear 1321, the third gear 1331 and the fourth gear 1341 may be circular gears, 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. With such a configuration, when the first gear 1311 rotates about 45 degrees (for example, 45 degrees to 90 degrees), the fourth gear 1341 can rotate two and a half turns, thereby realizing that when the handle is rotated 45 degrees (but not limited to 45 degrees, for example, 45 degrees to 90 degrees), the second end 1302 can rotate two and a half turns.

[0048] In this embodiment, a clutch mechanism is provided between the first end 1301 and the first gear 1311, and the clutch mechanism is used to separate or engage the first end 1301 and the first gear 1311. After the lock body is unlocked, the rotating shaft of the first end 1301 is engaged with the first gear 1311, and power can be transmitted between the handle and the lock core, and the lock can be unlocked through the handle.

[0049] Figure 5It is a schematic diagram of the structure of the gear set and clutch mechanism of the universal clutch device; Figure 6 yes Figure 5 A partial enlarged view of point A in the middle.

[0050] Reference Figure 5 and Figure 6 In one implementation, the clutch mechanism may include a rotating disk fixedly connected to the rotating shaft of the first end 1301. When the first end 1301 rotates, the rotating disk 1305 may rotate accordingly. A plug-in component 1307 ( Figure 6 ), the first gear 1311 is provided with a plug-in portion 1309 that plugs and cooperates with the plug-in component 1307, and the rotating disk and the first gear 1311 are separated or connected by the plug-in component 1307. In one implementation, a fixing block 1315 is provided on the side of the rotating disk 1305 close to the first gear 1311, and a mounting hole 1319 is provided on the fixing block 1315. The plug-in component 1307 is inserted into the mounting hole 1319 and can be inserted into or extended from both ends of the mounting hole 1309. The plug-in component 1307 can be a columnar body, such as a cylindrical pin, or a component of other shapes that can cooperate with the plug-in portion 1309. The plug-in portion 1309 is provided in the non-meshing area of ​​the first gear 1311, and can be provided at a position on the first gear 1311 that is away from the meshing area. The plug-in portion 1309 may be a plug-in slot provided on the first gear 1311 at a position opposite to the meshing area, but is not limited thereto. When the plug-in component 1307 is inserted into the plug-in portion 1309 on the first gear 1311, the rotating disk 1305 and the first gear 1311 are engaged and connected, and when the rotating disk 1305 rotates, the first gear 1311 can be driven to swing around the first end 1301 as the axis. In this embodiment, a reset spring may be provided in the mounting hole 1309 for mounting the plug-in component 1307, and the reset spring is used to enable the plug-in component 1307 to reset in time after movement.

[0051] After the clutch mechanism is set in the embodiment of the present application, the clutch mechanism can cooperate with the gear set. When unlocked, the turntable 1305 and the first gear 1311 are in a separated state, and turning the door handle will not transmit the driving force to the gear set, and the rotating shaft of the second end 1302 cannot be rotated through the gear set, and thus the lock cannot be unlocked; after unlocking, the turntable 1305 and the first gear 1311 are in an engaged state, and the door handle is turned to transmit the driving force to the gear set, and the rotating shaft of the second end 1302 is rotated through 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 universal door lock 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 original mechanical lock body square shaft and the distance between 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.

[0052] Reference Figure 4 , Figure 5 and Figure 6 The universal clutch device 130 provided in this embodiment includes a push rod mechanism, which is installed on one side of the gear set in the housing 1303. The push rod mechanism is used to drive the plug-in component 1307 to move so that the plug-in component 1307 can be plugged and matched with the plug-in portion on the first gear 1311. In one implementation, the push rod 1304 is arranged in the longitudinal direction, and the upper end of the push rod 1304 is arranged close to the plug-in component 1307, and the plug-in component 1307 is driven by the first movable member 1344 and the second movable member 1354 that are abutted in sequence. The lower end of the top rod 1304 is located at the bottom of the shell 1303, and the middle part of the first movable part 1344 is installed on the shell 1303 through the rotating shaft 1329, so that the first movable part 1344 can rotate around the rotating shaft 1329; the second movable part 1354 is elastically pressed against one end of the plug-in component 1307 on one side of the mounting hole 1319, and the installation of the second movable part 1354 is configured to be able to reciprocate in the direction of the insertion of the plug-in component 1307.

[0053] In this embodiment, the upper end of the push rod 1304 pushes upward against one end of the first movable member 1344, and the other end of the first movable member 1344 presses against the upper side of the second movable member 1354. When the push rod 1304 is driven to move upward, the upper end of the push rod 1304 supports one end of the first movable member 1344 upward, so that the other end of the first movable member 1344 rotates in the opposite direction, and the other end of the first movable member 1344 presses the second movable member 1354 downward, so that the second movable member 1354 abuts against the plug-in member 1307 and pushes the plug-in member 1307 into the plug-in slot 1309 along the direction of the mounting hole 1319, thereby engaging the rotating disk 1305 with the first gear 1311.

[0054] In one implementation, the push rod mechanism is further provided with a reset spring, which is used to reset the push rod mechanism in time after movement. After the push rod mechanism is reset, the plug-in 1307 and the first gear 1311 are in a separated state. The reset spring can be installed on the housing 1303 near the second movable member, and can act on the second movable member 1354 with elastic force, so that the second movable member 1354 can move elastically along the running direction of the plug-in 1307. When the driving force of the push rod 1304 is released, the second movable member 1354 applies a reverse supporting force to the first movable member 1344, so that the first movable member 1344 turns over and presses down the push rod 1304, so that the push rod 1304 moves downward. The setting of the reset spring enables the plug-in 1307 to disengage from the plug-in portion 1309 after the door lock is locked, so that the rotating disk 1305 and the first gear 1311 are automatically separated, so that the handle will not transmit the driving force to the first gear 1311, thereby achieving that the lock cannot be unlocked by the lock cylinder when the door is not unlocked.

[0055] In one implementation, a driving device for driving the top rod 1304 to move is provided in the shell 1303. The driving device may be a motor that can rotate forward and reversely. The motor is used to be connected to the control module of the smart door lock. The control module can control the operation of the motor and thereby drive the top rod 1304 to move.

[0056] In one implementation, a push block is provided between the driving device and the top rod 1304, and the push block can slide relative to the top rod 1304 in the direction of movement of the top rod 1304. A protrusion 1334 is provided laterally on the top rod 1304, and the upper end of the push block 1324 is pressed against the bottom of the protrusion 1334. The push block 1324 and the driving device 1314 are connected by a threaded transmission, and the driving device 1314 can drive the push block 1324 to move along the setting direction of the top rod 1304, thereby pushing the top rod 1304 to move upward.

[0057] In one implementation, the other end of the push rod 1304 extends out of the housing 1303 in the opposite direction of the driving. Since the push rod 1304 can slide relative to the push block 1324, the push rod 1304 can be moved upward by applying an external force to the end of the push rod 1304 extending out of the housing 1303, thereby engaging the turntable 1305 and the first gear 1311. After such a configuration, if the motor fails, a manual thrust can be applied to the end of the push rod 1304 extending out of the housing 1303 to move the push rod 1304 upward, which can achieve the effect of applying an upward thrust to the push rod outside the housing without using a driving device, thereby operating the push rod mechanism, which can be used as an emergency standby driving mode to facilitate the emergency unlocking function of the smart lock.

[0058] After the push rod mechanism is set in this embodiment, the push rod mechanism can cooperate with the clutch mechanism. When unlocked, the push rod 1304 is not subjected to an upward driving force, and the connector 1307 on the turntable 1305 is not inserted into the plug-in slot 1309 on the first gear, so that the turntable 1305 and the first gear 1311 are in a phase-separated state, and then the first end 1301 and the first gear 1311 are in a phase-separated state; after unlocking, the push rod 1304 is subjected to an upward driving force, and the push rod 1304 drives the connector 1307 to be stably inserted into the plug-in slot 1309 on the first gear 1311 through the first movable member 1344 and the second movable member 1354, so that the turntable 1305 and the first gear 1311 are in an engaged state, and then the first end 1301 and the first gear 1311 are engaged. Through such a setting, the movement of the top rod 1304 can be controlled by the control module of the smart door lock, so that the first end 1301 and the first gear 1311 are automatically separated or engaged through the clutch mechanism in the unlocking or locking scenario, so that the mechanical lock body and the quick-opening smart door lock can achieve better power connection and better installation adaptability.

[0059] In this embodiment, the push rod mechanism changes the transmission direction and transmission mode of the driving force of the connector, so that the layout of each mechanism in the shell 1303 is more reasonable. The various mechanisms will not interfere with each other during operation, so that the space in the shell 1303 can be fully utilized, which is conducive to the compact design of the product while ensuring performance.

[0060] It can be understood that the push rod mechanism in this embodiment is not limited thereto, and related components can be added or reduced to the push rod mechanism, and the installation positions of certain components can be changed according to actual needs.

[0061] Reference Figure 8 In this embodiment, the rotating shaft of the first end 1301 and the first gear 1311 are connected by a snap-fit ​​structure, which includes a slot 1336 disposed on the rotating shaft of the first end 1301, a first limiting portion 1316 and a second limiting portion 1326 are disposed in the slot 1336, and an arc-shaped limiting groove 1346 is disposed between the first limiting portion 1316 and the second limiting portion 1326. A snap-fit ​​portion is disposed on one side of the first gear 1311 close to the first end 1301, and a limiting block 1306 extends from the snap-fit ​​portion toward the slot. After the slot 1336 of the first end 1301 and the first gear 1311 are assembled, the limiting block 1306 on the first gear 1311 is received in the arc-shaped limiting groove 1346. When the handle is reset and the lock body is in the unlocked state, the limit block 1306 is pressed against the first limit portion 1316. When the handle drives the first end 1301 to rotate toward the side where the limit block 1306 is located, the first limit portion 1316 pushes the limit block 1306 to move, so that the first gear 1311 rotates together with the limit block. At this time, the gear group drives the second end 1302 to rotate toward the locking direction of the lock core, thereby achieving locking. After locking, the handle and the rotating shaft can be elastically reset. Such a setting makes it more convenient to lock the lock body. When the handle is turned upward by 45 degrees (but not limited to 45 degrees, such as 45 degrees-90 degrees), fast locking can be achieved.
