Description

Technical Field

[0001] The utility model relates to the technical field of door locks, and in particular to an intelligent door lock handle quick-release structure and an intelligent door lock. Background Art

[0002] Currently available smart door locks typically connect the handle to the lock housing with screws. After the faceplate and handle are assembled, the faceplate and handle are then installed on the door. When installing the front and back panels of a smart door lock, the handle unlocking shaft is usually inserted into the lock body first, and then the lock faceplate with the handle attached is passed through the unlocking shaft. In practice, depending on the direction or habit of opening the door, it may be necessary to reverse the handle, such as from left-hand to right-hand.

[0003] Once the panel and handle are fixed together, the handle cannot be changed. To adjust the handle's direction, the original assembly between the handle and the panel must be disassembled, the handle must be repositioned, and then reassembled with the panel. However, current handle disassembly and assembly are not convenient, and reinstalling the unlocking square shaft also poses difficulties in aligning the shaft and hole. This results in high repetitive labor and low installation efficiency. Utility Model Content

[0038] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0041] In addition, in this utility model, the descriptions of "first" and "second" are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0042] The utility model proposes a smart door lock handle quick release structure, referring to Figure 1 The smart door lock handle quick-release structure includes a panel assembly 1, a shaft assembly 2, and a handle assembly 3. The panel assembly 1 has an assembly hole 11, and the shaft assembly 2 is rotatably mounted in the assembly hole 11. The shaft assembly 2 has an unlocking end 241 and an operating end 221. Both the unlocking end 241 and the operating end 221 extend out of the panel assembly 1. The unlocking end 241 is connected to the lock body 4 of the smart door lock.

[0043] The handle assembly 3 has a locked state and an unlocked state. In the locked state, the handle assembly 3 is locked with the operating end 221. When the handle assembly 3 is subjected to an external force, it can drive the shaft assembly 2 to rotate through the operating end 221; in the unlocked state, the handle assembly 3 is released from the lock with the operating end 221, and the handle assembly 3 can be separated from the operating end 221.

[0044] Based on the above-mentioned scheme, the operator only needs to operate to switch the locking state of the handle assembly 3, so that the handle assembly 3 can be quickly detached from or installed with the shaft assembly 2, thereby realizing the rapid disassembly and assembly of the handle of the smart door lock, and the handle assembly and the shaft assembly are detachable, and the installation order of the unlocking parts in the shaft assembly can be changed, that is, after the handle assembly and the panel assembly are assembled together and fixed on the door, the unlocking parts in the shaft assembly can be installed from the outside of the panel assembly. Such a setting, on the one hand, reduces the steps of handle reversal adjustment and reduces complicated operations, and on the other hand, when installing the unlocking parts, it can reduce the inconvenience of hole-axis alignment of multiple parts, which helps to improve the convenience of installation, greatly reduce the operating burden of the installer, and reduce repetitive labor, thereby effectively improving the efficiency of disassembling and assembling the smart door lock handle 31.

[0045] Reference Figures 1 to 7 The handle assembly 3 includes a door lock handle 31, a limiting member 32 and a driving assembly 33. The door lock handle 31 has a connecting portion 311, which is used to connect to the operating end 221. The limiting member 32 is movably provided on the connecting portion 311, and the driving assembly 33 is movably connected to the connecting portion 311. In the locked state, the driving assembly 33 drives the limiting member 32 to limit the operating end 221 and the connecting portion 311, so that the connecting portion 311 and the rotating shaft assembly 2 are not separated from each other in the axial direction of the rotating shaft assembly 2. In the unlocked state, the driving assembly 33 is acted upon by an external force and drives the limiting member 32 to release the limit on the operating end 221 and the connecting portion 311, so that the connecting portion 311 and the rotating shaft assembly 2 are separated in the axial direction of the rotating shaft assembly 2.

[0046] With such a configuration, when the door lock handle 31 needs to be removed, it is only necessary to apply external force to the drive assembly 33 so that the drive assembly 33 can drive the limiter 32 to release the limit on the connecting portion 311 and the operating end 221, and the connecting portion 311 is disengaged from the operating end 221, that is, the handle assembly 3 is disengaged from the shaft assembly 2, thereby achieving quick and convenient disassembly of the handle assembly 3, with fewer disassembly steps and high disassembly efficiency, so that the direction of the door lock handle 31 can be conveniently adjusted to adapt to different door opening directions and door opening habits of different users.

[0047] When installing the door lock handle 31, a force is applied to the drive assembly 33 so that the handle assembly 3 remains in the unlocked state. Then, the handle assembly 3 only needs to be placed on the operating end 221, and the force applied to the drive assembly 33 is released so that the handle assembly 3 returns to the locked state. The limit member 32 automatically locks the operating end 221 under the action of the drive assembly 33, that is, locks the connection with the shaft assembly 2, thereby quickly and conveniently completing the installation of the door lock handle 31.

[0048] The door lock handle 31 provides convenient operation for the operator. When in the locked state, the user can rotate the door lock handle 31 to rotate the shaft assembly 2, thereby unlocking or locking the lock body 4, thereby unlocking or locking the door lock. The door lock handle 31 includes a handle body 312 and a decorative shell 313. The connecting portion 311 is formed on the handle body 312. The decorative shell 313 is fixed to the side of the handle body 312 away from the connecting portion 311 via screws. The decorative shell 313 serves as a decorative handle, enhancing the aesthetics of the handle body 312 and improving the user experience.

[0049] Reference Figures 1 to 7 A hollow accommodating cavity 314 is formed within the connecting portion 311, and the operating end 221 is disposed within the accommodating cavity 314. A mounting hole 315 is defined on the outer peripheral wall of the connecting portion 311, communicating with the accommodating cavity 314. The limiting member 32 is movably disposed within the mounting hole 315. A limiting ring groove 222 is defined on the outer peripheral wall of the operating end 221, and the mounting hole 315 corresponds to the limiting ring groove 222. In the locked state, under the action of the driving assembly 33, a portion of the limiting member 32 falls into the limiting ring groove 222, while the other portion lies within the mounting hole 315, thereby limiting the connection portion 311 and the operating end 221. In the unlocked state, the limiting member 32 withdraws from the limiting ring groove 222, releasing the limiting effect on the connection portion 311 and the operating end 221.

[0050] The handle assembly 3 and the rotating shaft assembly 2 are limited by the limiting member 32. The structure is simple and ingenious. There is no need to limit the handle assembly 3 and the rotating shaft assembly 2 through a complex structure. This not only helps to improve the convenience of disassembly and assembly of the handle assembly 3, but also saves structural space and improves the structural compactness of the smart door lock handle quick-release structure.

[0051] Among them, an elastic contraction part (not shown in the figure) is formed at the opening of the mounting hole 315 near the accommodating cavity 314. When in the locked state, the limit member 32 squeezes the elastic contraction part so that the limit member 32 partially falls into the limit ring groove 222; when in the unlocked state, the elastic contraction part elastically supports the limit member 32.

[0052] On the one hand, the elastic shrinkage portion provides support for the limit member 32 to prevent the limit member 32 from falling into the accommodating cavity 314, so that the limit member 32 can be stably set in the mounting hole 315. On the other hand, the elastic shrinkage portion can be shrunk or expanded to ensure that the limit member 32 can fall from the mounting hole 315 into the limit ring groove 222 to form a lock for the connecting portion 311 and the operating end 221, so that the handle assembly 3 and the shaft assembly 2 restrict each other in the axial direction of the shaft assembly 2, effectively preventing the connecting portion 311 from being separated from the operating end 221, thereby realizing a locked connection between the handle assembly 3 and the shaft assembly 2.

[0053] It can be understood that the elastic shrinkage part can be a silicone ring, which is fixed to the open edge of the mounting hole 315 near the accommodating cavity 314, and the side of the silicone ring near the accommodating cavity 314 is arranged in a narrow mouth shape; the elastic shrinkage part can be an elastic funnel structure, which is fixed to the open edge of the mounting hole 315 near the accommodating cavity 314, and the side of the elastic funnel structure near the accommodating cavity 314 is arranged in a narrow mouth shape; the elastic shrinkage part can also be other structural parts with elastic shrinkage function, which are not specifically limited here.

[0054] The stopper 32 is a spherical structure. There are multiple stoppers 32 and multiple mounting holes 315. The multiple mounting holes 315 are spaced apart along the circumference of the connecting portion 311, and the multiple stoppers 32 are disposed in a one-to-one correspondence within the multiple mounting holes 315. This arrangement further enhances the locking force between the handle assembly 3 and the rotating shaft assembly 2. When locked, it ensures the locking stability of the door lock handle 31 and the rotating shaft assembly 2, effectively reduces the possibility of shaking or loosening of the door lock handle 31, improves the reliability of the smart door lock handle quick-release structure, and enhances the user experience.

[0055] The limiting member 32 may be a spring steel ball, a marble structure, or other structural members with a locking and limiting function, which is not specifically limited here.

[0056] Continue to refer to Figures 1 to 7The drive assembly 33 includes a sleeve 331, a first elastic member 332, and a stopper 333. The first elastic member 332 is disposed within the sleeve 331 and, together with the sleeve 331, is sleeved on the exterior of the connecting portion 311. The connecting portion 311 is arranged in a stepped shape. A pushing portion 3311 is formed within the sleeve 331 for pushing the limiting member 32 to move. One end of the first elastic member 332 abuts against the outer peripheral wall of the connecting portion 311, and the other end abuts against the pushing portion 3311. The stopper 333 is connected to the end of the connecting portion 311 away from the door lock handle 31 and is used to axially limit the sleeve 331.

[0057] When the door lock handle 31 needs to be removed, the operator pulls the sleeve 331 to move away from the panel assembly 1, the sleeve 331 compresses the first elastic member 332, and the pushing portion 3311 gradually disengages from the contact with the limit member 32 until the pushing portion 3311 releases the squeezing of the limit member 32, so that the constraint of the limit member 32 is released. The operator only needs to hold the door lock handle 31 and pull the door lock handle 31. The door lock handle 31 drives the connecting portion 311 to move in the direction away from the panel assembly 1. The connecting portion 311 drives the limit member 32 to move and gradually forces the limit member 32 to retreat from the limit ring groove 222 to the mounting hole 315 until the door lock handle 31 is disengaged from the rotating shaft assembly 2, thereby completing the removal of the door lock handle 31.

[0058] Among them, the connecting part 311 can be set as a stepped shaft, the pushing part 3311 can be set as a convex ring, and the two end faces of the convex ring along the axial direction of the sleeve 331 are set as planes, so as to provide support for the first elastic part 332, and can also form a plane stop with the stop part 333, effectively preventing the sleeve 331 from separating from the connecting part 311.

[0059] The outer wall of the sleeve 331 is provided with an anti-slip structure to increase the external friction of the sleeve 331, thereby enhancing the operator's grip on the sleeve 331. The anti-slip structure can be a thread, anti-slip bumps, or anti-slip silicone. The stopper 333 can be a stop ring or a stop pin, and the first elastic member 332 can be a spring or other elastic sleeve.

[0060] Continue to refer to Figures 1 to 7 The door lock handle 31 forms a clearance ring groove 316 along the circumference of the connecting portion 311, and the clearance ring groove 316 provides a clearance space 317 for the shaft sleeve 331; the pushing portion 3311 and the opening of the shaft sleeve 331 away from the door lock handle 31 form a clearance space 317. When in the unlocked state, the clearance space 317 provides a clearance space 317 for the limit member 32.

[0061] With this arrangement, when a force is applied to the sleeve 331, causing it to move away from the panel assembly 1, the clearance groove 316 allows the sleeve 331 to partially extend into the door lock handle 31. This not only maintains the overall aesthetics of the door lock handle 31, but also effectively utilizes the structural space of the door lock handle 31, making the handle assembly 3 more compact. As the push portion 3311 gradually disengages from the stopper 32, the clearance space 317 provides room for the stopper 32 to move, allowing the stopper 32 to remain on the connecting portion 311.

[0062] The accommodating cavity 314 includes a special-shaped cavity segment 3141 and a circular cavity segment 3142, which are distributed in sequence from the bottom of the accommodating cavity 314 to the open end. The operating end 221 includes a transmission part 223 and a rotating part 224. The transmission part 223 extends into the special-shaped cavity segment 3141 and cooperates with the wall limit of the special-shaped cavity segment 3141. The rotating part 224 is rotatably arranged in the circular cavity segment 3142.

[0063] With such a configuration, in the locked state, the operator can drive the shaft assembly 2 to rotate through the handle assembly 3 to unlock or lock the lock body 4, thereby unlocking or locking the door, and can also provide rotation space for the rotating part 224 through the circular cavity section 3142 to avoid affecting the rotation of the shaft assembly 2.

[0064] Among them, the cross-section of the special-shaped cavity segment 3141 can be set in a rectangular or square shape, or in a triangular or hexagonal shape, or in other shapes, as long as it is ensured that the transmission part 223 can form a limiting contact when extending into the special-shaped cavity segment 3141, and no specific limitation is made here.

[0065] In the unlocked state, the door lock handle 31 can switch its direction relative to the rotating shaft assembly 2 in a clockwise or counterclockwise direction. For example, in the unlocked state, the door lock handle 31 is disengaged from the rotating shaft assembly 2, and the door lock handle 31 can be rotated once by 90 degrees in the clockwise direction, and then rotated again by 90 degrees in the clockwise direction; or the door lock handle 31 can be rotated once by 90 degrees in the counterclockwise direction, and then rotated again by 90 degrees in the counterclockwise direction; thereby adjusting the direction of the door lock handle 31 according to the door opening direction or door opening habits, thereby achieving quick and convenient adjustment of the direction of the door lock handle 31.

[0066] The assembly process of the handle assembly 3 is as follows: the limit member 32 is placed in the mounting hole 315 in advance, the first elastic member 332 is put on the connecting portion 311, and then the sleeve 331 is put on the connecting portion 311. After that, the sleeve 331 is pushed to the maximum compression stroke position, and finally the stop member 333 is installed on the connecting portion 311 to limit the axial disengagement of the sleeve 331, thereby completing the installation of the handle assembly 3.

[0067] The disassembly process of the handle assembly 3: the operator pulls the sleeve 331 to move away from the panel assembly 1, the sleeve 331 compresses the first elastic member 332, and the pushing portion 3311 gradually disengages from the contact with the limit member 32 until the pushing portion 3311 releases the squeezing of the limit member 32, so that the constraint of the limit member 32 is released. The operator only needs to hold the door lock handle 31 and pull the door lock handle 31. The door lock handle 31 drives the connecting portion 311 to move in the direction away from the panel assembly 1. The connecting portion 311 drives the limit member 32 to move and gradually forces the limit member 32 to retreat from the limit ring groove 222 to the mounting hole 315 until the door lock handle 31 is disengaged from the rotating shaft assembly 2, thereby completing the disassembly of the door lock handle 31.

[0068] Continue to refer to Figures 1 to 7 The shaft assembly 2 includes a bearing assembly 21, a rotating member 22, a reset member 23, and an unlocking member 24. The bearing assembly 21 is disposed within the assembly hole 11, the rotating member 22 passes through the assembly hole 11, and the bearing assembly 21 is also sleeved on the exterior of the rotating member 22. One end of the reset member 23 is connected to the panel assembly 1, and the other end is connected to the rotating member 22. The reset member 23 provides a restoring force for the rotating member 22. The operating end 221 is formed at the end of the rotating member 22 facing the handle assembly 3. The unlocking member 24 is embedded in the rotating member 22 and can rotate synchronously with the rotating member 22. The unlocking end 241 is formed at the end of the unlocking member 24 facing the lock body 4.

[0069] The bearing assembly 21 includes a bearing 211 and an end cap 212. The end cap 212 is used to secure the bearing 211 within the assembly hole 11. The bearing 211 is nested in the outer peripheral wall of the rotating member 22. The bearing 211 supports the rotating member 22 and reduces the friction of the rotating member 22, allowing the rotating member 22 to rotate smoothly. This helps improve the smoothness of the rotation of the rotating member 22 and enhances the smoothness of unlocking or locking the lock body 4.

[0070] It is understandable that the reset member 23 may be a torsion spring or other structural member that provides reset for the rotating member 22. The unlocking member 24 may be an unlocking square shaft.

[0071] The rotating member 22 passes through the limiting channel 225 along its length direction, and the unlocking member 24 is limitedly matched with the inner wall of the limiting channel 225. In the locked state, the unlocking member 24 can extend into the limiting channel 225 from the open end away from the handle assembly 3.

[0072] With such a configuration, during the installation process, the unlocking member 24 can be inserted outside the panel assembly 1, which not only improves the convenience of installing the unlocking member 24, but also reduces the difficulty for the operator to align the lock panel with the unlocking member 24, thereby greatly reducing the assembly requirements.

[0073] The external shape of the unlocking member 24 is adapted to the shape of the limiting channel 225. The cross-section of the limiting channel 225 can be rectangular or square, triangular or hexagonal, or other shapes. As long as it is ensured that the unlocking member 24 can form a limiting contact when it extends into the limiting channel 225, so that the unlocking member 24 and the rotating member 22 rotate synchronously, no specific limitation is made here.

[0074] The shaft assembly 2 further includes a second elastic member 25 , which is disposed in the limiting channel 225 , with one end abutting against the handle assembly 3 and the other end abutting against the unlocking member 24 . The second elastic member 25 is used to provide axial support force for the unlocking member 24 .

[0075] The unlocking member 24 is provided with a limiting protrusion 242 on its outer peripheral wall. This protrusion 242 is used to limit the position of the unlocking member 24, thereby limiting the depth of the unlocking member 24's penetration into the lock body 4, ensuring that the unlocking member 24 extends to the appropriate depth. When the unlocking member 24 extends into the rotating member 22, the limiting protrusion 242 cooperates with the limiting channel 225. Once fully inserted, the distal end of the limiting protrusion 242 abuts the lock body 4, providing an axial limiting effect. A second elastic member 25 allows the unlocking member 24 to elastically abut the lock body 4, increasing the installation stability of the unlocking member 24 and improving the reliability and stability of the unlocking member 24 in unlocking or locking the lock body 4.

[0076] The second elastic member 25 may be a spring or other structural member with elastic properties.
