The intelligent lock has become a common door lock in the field of furniture locks, and the components of the common intelligent lock are made of metal materials, so that noise can be generated due to collision or friction between all parts when the door is opened or closed. With the increase in the level of consumer consumption, it is desirable to minimize such noise in offices or in home applications. The spring bolt of the lock body in the prior art is always acted by the axial force of the spring, and the spring is required to be compressed in the process of sliding the lock body into the lock body through the contact between the tongue body and the door frame when the door is opened and closed, and the spring can push the tongue body to rapidly stretch out after the door frame is separated from the tongue body, so that the impact force of the tongue body on the lock body shell is large, and noise generated by the reset of the tongue body is large.

Referring to fig. 1, a door lock 3000 is provided in this embodiment, referring to fig. 1, an intelligent door lock 3000 is provided in this embodiment, and the intelligent door lock comprises a lock 1000 and a lock panel (not shown), wherein the lock panel may include a driving component, a handle, and the like, and the lock is electrically connected or in transmission connection with the lock panel. The lock is disposed on the door and the door frame in cooperation with the side plate 2000. In some embodiments, the lock 1000 may be disposed on a door panel and the side panel 2000 may be disposed on a door frame. In other embodiments, the lock 1000 can also be provided on a door frame and the side panel 2000 provided on a door panel. The door panel can rotate relative to the door frame, and the lock 1000 can be selectively coupled to or decoupled from the side panel 2000 to close or open the door. As an embodiment, the lock 1000 and the side plate 2000 may be disposed on the same horizontal plane. In other embodiments, the side plate 2000 can also be disposed on the same vertical line as the lock 1000, which is not limited herein.

The lock 1000 includes a housing 900, a locking bolt 800, a reset assembly 700, and a driver 600. The housing 900 has a receiving cavity 930 formed therein, and the housing 900 is provided with a locking hole 911, the locking hole 911 communicating with the receiving cavity 930. Referring to fig. 2, in this embodiment, the lock tongue 800 may include a tongue body 810 and a connecting post 820 disposed along an axis direction of the lock hole 911, the connecting post 820 is in transmission connection with the tongue body 810, the lock tongue 810 is movably disposed along the axis of the lock hole 911, and the tongue body 810 may selectively extend or retract along the lock hole 911 to the accommodating cavity 930. The reset assembly 700 is disposed within the receiving cavity 930 and is configured to urge the tongue 810 along the protruding latch hole 911. The driving member 600 is also disposed in the receiving chamber 930 and is in driving connection with the reset assembly 700 to drive the reset assembly 700 to move.

The housing 900 includes a bottom case 920 and a guide plate 910 mounted on the bottom case 920, specifically, the guide plate 910 is mounted on one side edge of the bottom case 920, and is used for being opposite to the side plate 2000 when being mounted, other edges of the bottom case 920 are bent, so that the bottom case 920 and the guide plate 910 enclose a receiving cavity 930, and the lock tongue 800 is located in the receiving cavity 930. The guide plate 910 is provided with a locking hole 911, and the locking hole 911 penetrates the guide plate 910. The guide plate 910 is substantially perpendicular to the bottom chassis 920, so that an axis of the locking hole 911 provided on the guide plate 910 may also be substantially parallel to the bottom chassis 920. In some embodiments, a fixing hole (not shown) may be further provided on the guide plate 910, and the fixing hole is used to mount the lock 1000 on the door panel or the door frame.

The lock tongue 800 may be telescopically disposed along the axial direction of the lock hole 911, and may be selectively extended at least partially out of the lock hole 911 or retracted into the accommodating chamber 930. A locking hole (not shown) is provided in the side plate 2000, and the locking hole is provided corresponding to the locking hole 911, and the locking tongue 800 may extend out of the locking hole 911 and be inserted into the locking hole so that the door is in a locked state. In some embodiments, in this example, the locking hole 911 may be a substantially square hole and substantially the same outer contour as the locking bolt 800, such that when the locking bolt 800 is disposed in the locking hole 911, the locking bolt 800 cannot rotate along the axis of the locking hole 911 in the locking hole 911. In other embodiments, the locking hole 911 may be formed in other shapes, which is not limited herein. In some embodiments, an anti-lock hole 911 may also be provided on the guide plate 910. The lock 1000 may further include a plurality of anti-lock bolts 800 (not shown), and the plurality of anti-lock bolts 800 may be coupled to extend into or out of the anti-lock hole 911 together and to back lock the lock 1000.

The latch 800 includes a tongue body 810 and a connecting post 820 that are telescopically arranged along the axial direction of a latch hole 911. The tongue 810 may be inserted into the locking aperture to limit rotation of the door panel relative to the door frame. For example, referring to fig. 3, a slant 811 is disposed on an end of the tongue 810 away from the connecting post 820, and the slant 811 can extend or retract into the locking hole 911 along with the extension and retraction of the tongue 810. The inclined surface 811 may form an angle with a plane in which the bottom chassis 920 is located, and the bottom chassis 920 may be disposed substantially parallel to the door panel. Thus, the door panel can also be at a certain angle to the bevel 811. In this way, in the process of mutually rotating the door frame and the door panel to be closed, the inclined surface 811 can be abutted with the side plate 2000 arranged on the door frame, and the side plate 2000 can slide along the inclined surface 811 and apply a component force to the tongue 810 along the direction of the lock hole 911, so as to push the tongue 810 to be embedded into the accommodating cavity 930 along the lock hole 911.

The connecting post 820 is used to locate the tongue 810. In the present embodiment, the length direction of the connection post 820 is along the axial direction of the lock hole 911, and the connection post 820 includes a first end 821 and a second end 822 opposite to each other. The tongue 810 is hinged to the first end 821 such that the tongue 810 can rotate relative to the length of the post 820, i.e., rotate about an axis perpendicular to the locking hole 911 to connect with the post 820.

In some embodiments, the lock 1000 may further include a pivot 100, with the first end 821 being hinged to the tongue 810 by the pivot 100. The axial direction of the pivot shaft 100 and the axial direction of the lock hole 911 may be substantially perpendicular to each other. Thus, the hinge shaft 100 can be guaranteed to be hinged to the door frame and the door panel in the same direction, and the tongue 810 can rotate relative to the connecting post 820 in the lock hole 911. A push plane 812 is also provided on the tongue 810 on the side opposite the bevel 811. When the tongue 810 extends out of the locking hole 911, the push plane 812 may be substantially parallel to the axis of the locking hole 911. When the tongue 810 is inserted into the door frame or the side plate 2000, the side plate 2000 can abut against the pushing plane 812 when the door panel is pushed by a user, and a force perpendicular to the pushing plane 812 is provided to the pushing plane 812. If the tongue 810 is in the locked state, the door frame abuts against the pushing plane 812, so that the lock 1000 locks the door frame and the door panel to realize the locking function. The tongue 810 is retractable and rotatable relative to the locking hole 911 when in the unlocked state. Therefore, the user can pull the door panel and make the pushing plane 812 abut against the door frame, and the door frame can drive the tongue 810 to rotate and make the pushing plane 812 form a certain angle with the door frame. The user continues to pull the door frame, the side plate 2000 can slide along the inclined pushing plane 812, and a component force along the axial direction of the lock hole 911 is applied to the tongue 810, so that the tongue 810 is retracted into the lock hole 911. Thus, the user can directly open the door by pulling the door panel.

When the tongue 810 contacts the side plate 2000, there may be a problem in that noise is excessively generated. In some embodiments, noise reduction members 813 may also be provided on the tongue 810. Referring again to fig. 2, noise reducer 813 may be a separate piece disposed along bevel 811 and push plane 812. Illustratively, mounting grooves 814 are provided on the inclined surface 811 and the push surface 812, and the noise reduction member 813 is embedded in the mounting grooves 814 and protrudes from the mounting grooves 814. When the pushing plane 812 or the inclined plane 811 faces the side plate 2000, the noise reduction piece 813 first abuts the side plate 2000. The noise reduction member 813 may be a member made of a material having a certain impact resistance such as a hard plastic, so that when the door frame abuts against the noise reduction member 813, noise generated in part can be reduced.

The reset assembly 700 and the driving member 600 are used for driving the tongue 810 to reset or to enable the tongue 810 to be in a free state. Referring to fig. 1 and 4, the reset device 700 is selectively located at the first position and the second position. The driving member 600 is configured to receive a driving force and drive the reset assembly 700 to selectively be located at the first position or the second position. When the reset assembly 700 is located at the first position, the reset assembly 700 abuts against the tongue 810, so that the tongue 810 extends out of the lock hole 911, and when the driving member 600 drives the reset assembly 700 to be located at the second position, the reset assembly 700 is separated from the tongue 810, so that the tongue 810 is in a free state without stress. In the door opening process, the reset assembly 700 can be separated from the tongue 810 through the driving piece 600, so that the tongue 810 is in a free state without stress, and then other acting forces acting on the tongue 810 are not overcome when the door frame contacts and pushes the tongue 810, so that larger impact noise can not be generated when the door frame contacts with the tongue 810; moreover, after the door is opened, the tongue 810 is pushed by the reset assembly 700 to extend out of the lock hole 911 for reset. In the resetting process, since the driving member 600 and the resetting assembly 700 are connected and driven, the driving member 600 can also limit the speed of the resetting assembly 700 moving from the second position to the first position, thereby limiting the speed of the tongue 810 extending out of the lock hole 911.

In some embodiments, reset assembly 700 includes reset pusher 701 and reset element 610. The reset pusher 701 may slide along the bottom case 920, and the reset element 610 is configured to drive the reset pusher 701 to move toward the guide plate to move the reset assembly 700 from the second position to the first position. For example, the restoring element 610 may be sleeved on the connecting post 820, where one end of the restoring element 610 abuts against the restoring push seat 701, and the other end may abut against the bottom shell 920. When in the first position, the reset element 610 is in an initial compression state, one end of the reset pushing seat 701 abuts against the tongue 810, and the reset force of the reset element 610 can push the reset pushing seat 701, so that the reset pushing seat 701 applies a reset force towards the lock hole 911 to the tongue 810. The driving member 600 can drive the reset pushing seat 701 to move to reach the second position, where the reset member 610 is in a further compressed state, and the reset pushing seat 701 is separated from the tongue 810. In other embodiments, the reset pushing seat 701 may be rotatably disposed on the bottom case 920, and selectively located at the first position or the second position by rotation, where the movement manner of the reset pushing seat 701 is not limited.

Illustratively, the reset pushing seat 701 is provided with a through hole 710, and the axial direction of the through hole 710 is the same as the axial direction of the lock hole 911, and the reset pushing seat 701 is sleeved on the connecting post 820 through the through hole 710, so that the connecting post 820 slidably penetrates through the through hole 710. In this way, during the process of moving the reset pushing seat 701 from the first position to the second position, the reset pushing seat 701 can slide along the connecting post 820 and be separated from the tongue 810.

During the sliding process of the reset pushing seat 701, there may be a problem that the sliding direction is deviated. In some embodiments, the reset pushing seat 701 is provided with a protrusion 720, and the bottom case 920 is provided with a sliding groove (not shown), in which the protrusion 720 is embedded and slides along the sliding groove. Since the protrusion 720 is embedded in the sliding groove, the movement direction of the protrusion 720 is limited, so that the protrusion can only move along the sliding groove direction, and thus, the sliding direction of the reset pushing seat 701 is not easy to deviate.

Referring to fig. 2 and 3 again, in some embodiments, the tongue 810 may further be provided with a first limiting portion 815, and the reset pushing seat 701 is provided with a second limiting portion 740, and when the reset pushing seat 701 is switched from the second position to the first position, the first limiting portion 815 may contact the second limiting portion 740, so that the tongue 810 extends out of the lock hole 911 along a certain angle. Specifically, the first limiting portion 815 includes a first pushing position 8151 and a second pushing position 8152, which are disposed on the surface of the tongue body, the first pushing position 8151 and the second pushing position 8152 are disposed on two sides of the connecting post 100, and when the second limiting portion 740 contacts with the first limiting portion 8151, the tongue body 810 rotates to enable the first pushing position 8151 and the second pushing position 8152 to be connected with the second limiting portion 740. In this manner, the tongue 810 can extend out of the locking hole 911 at a suitable angle, and the push plane 812 on the tongue 810 can be substantially perpendicular to the guide plate 910.

Referring to fig. 5 and fig. 6, the driving member 600 includes a first toothed disc 620 and a second toothed disc 630 coaxially rotatably disposed on a bottom shell 920, where the first toothed disc 620 is configured to receive a driving force. The driving force may be power supplied by a motor or power supplied when the user rotates the rotary handle, and is not limited herein. The second fluted disc 630 is in transmission connection with the reset pushing seat 701, the first fluted disc 620 is provided with a first transmission part 621, the second fluted disc 630 is provided with a second transmission part 631, and when the reset pushing seat 701 is switched from the first position to the second position, the first transmission part 621 is separated from the second transmission part 631; the first transmission portion 621 is in transmission connection with the second transmission portion 631 during the process of switching the reset pushing seat 701 from the second position to the first position.

Specifically, a rack 730 may be disposed on the reset pushing seat 701, the rack 730 extends along an axial direction of the lock hole, and the second toothed disc 630 is engaged with the rack 730 on the reset pushing seat 701. The reset pushing seat 701 can be driven to slide along a straight line by the rotation of the second toothed disc 630. In other embodiments, the reset pushing seat 701 and the second toothed disc 630 may be connected by other transmission methods, for example, a rocker is disposed on one side of the second toothed disc 6300, and the rocker is hinged to the reset pushing seat 701, so that the reset pushing seat 701 can be driven to slide, which is not limited herein.

In this embodiment, the first toothed disc 620 is disposed coaxially with the second toothed disc 630. The first transmission portion 621 is disposed on a surface of the first toothed disc 620 facing the second toothed disc 630, the second transmission portion 631 includes an arc-shaped slot 6311 disposed on the second toothed disc 630, the arc-shaped slot 6311 includes a first end 6322 and a second end 6323 opposite to each other, and the first transmission portion 621 is at least partially embedded in the arc-shaped slot 6311. When the first toothed disc 620 rotates along the first rotation direction under the action of the positive driving force, the first transmission portion 621 can abut against the first end 6322 to drive the second toothed disc 630 to rotate synchronously with the first toothed disc 620, so as to drive the reset pushing seat 701 to move in a direction away from the guide plate 910, so that the reset pushing seat 701 moves from the first position to the second position. In the second position, the tongue 810 is separated from the reset pushing seat 701, and the door frame contacts the tongue 810 during the door opening process, so that less noise is generated when the door frame is retracted into the housing 900. After the door is opened, the reset pushing seat 701 can be switched from the second position to the first position to push the tongue 810 to extend out of the lock hole 911 for reset. At this time, under the action of the reset element 610, the reset pushing seat 701 can move from the second position to the first position, and during the moving process, the reset pushing seat 701 drives the second toothed disc 630 to rotate along the second rotation direction opposite to the first rotation direction. Because the first end 6322 and the first transmission portion 621 still maintain the abutting relationship, the rotation of the second toothed disc 630 is limited by the first toothed disc 620, and the reverse driving force applied to the first toothed disc 620 can drive the first toothed disc 620 to rotate along the second rotation direction and control the rotation speed of the first toothed disc 620, so that the rotation speed of the second toothed disc 630 and the movement speed of the reset pushing seat 701 are in a controllable state, thereby avoiding the occurrence of a large impact force between the too high extending speed and the guide plate 910 when the tongue 810 is reset, and avoiding the occurrence of a large noise when the tongue 810 is reset.

When the tongue 810 extends to a certain distance, the limiting part on the connecting post 820 makes the tongue 810 unable to extend continuously, and the movement of the reset pushing seat 701 stops. As the first toothed plate 620 continues to rotate, the first transmission portion 621 begins to slide along the arcuate slot 6311 from the first end 6322 to the second end 6323, and at this time, the first toothed plate 620 is separated from the second toothed plate 630. Because the driving force drives the first fluted disc 620 to rotate slowly, the rotation speed of the second fluted disc 630 and the moving speed of the reset pushing seat 701 are slow, and slow reset of the tongue 810 can be realized, so that noise generated when the tongue 810 collides with the side plate 2000 or the door frame in the rebound process of the tongue 810 is small, and meanwhile, damage to parts caused by collision is not easy.

When the reset assembly 700 is at the first position, if the tongue 810 is pushed by the door frame or the side plate 2000 along the axial direction of the lock hole 911, the tongue 810 will retract along the lock hole 911 and push the reset pushing seat 701 to move from the first position to the second position, during this process, the reset pushing seat 701 drives the second fluted disc 630 to rotate along the first rotation direction, at this time, the first transmission part 621 can move in the arc-shaped groove 6311, but not drive the first fluted disc 620 to rotate, which is equivalent to forming a certain virtual position, so that during the process of the tongue 810 being collided and retracted into the lock hole 911, the power source will not be reversely driven, thereby avoiding damage to the internal parts.

In other embodiments, the first toothed disc 620 and the second toothed disc 630 may be drivingly connected by a clutch. The clutch may be a mechanical clutch or an electronic clutch, and is not limited herein. When the reset pushing seat 701 is switched from the second position to the first position, the clutch can lock the rotation between the first toothed disc 620 and the second toothed disc 630, so that when the second toothed disc 630 rotates, the first toothed disc 620 will also rotate along with it, and the reset pushing seat 701 is limited to move too fast due to the thrust of the reset piece 610. When the reset pushing seat 701 is switched from the first position to the second position, the reset pushing seat 701 drives the first toothed disc 620 to rotate, and at this time, the clutch separates the first toothed disc 620 from the second toothed disc 630, and the first toothed disc 620 does not drive the second toothed disc 630 when rotating, so as to realize the function of protecting the power source of the driving force.

In other embodiments, referring to fig. 8, the driving member 600 may also include a latch dial, where the latch dial is rotatably disposed on the bottom shell 930, and the latch dial further has a latch 601 selectively abutting against the reset push seat 701, so as to drive the reset push seat 701 to move when the latch dial 600 rotates. For example, the latch dog dial block may be rotatably disposed on the bottom shell 930, where the latch dog dial block further has a dial tongue 601, and the dial tongue 601 may selectively abut against the reset push seat 701, so as to drive the reset push seat 701 to move when the latch dog dial block rotates. Correspondingly, a driving portion 702 corresponding to the pulling tongue 61 may be disposed on the reset pushing seat 701, and the driving portion 702 is disposed near the pulling tongue 601. The driving portion 702 may be formed by bending a portion of the reset pushing seat 701 toward the dial tongue 601, where the bent portion is located on a movement track of the dial tongue 601. When the bolt pulling block rotates, the pulling tongue 601 abuts against the driving part 702 on the reset pushing seat 701, and can limit the extending speed of the bolt 810.

The driving force may be directly obtained using the second toothed disc 630, but there may be a problem in that the direction of the driving force is opposite to the driving direction. In some embodiments, lock 1000 may also include gear 500. In some embodiments, a square hole may be provided on the axis of the gear 500, and the lock 1000 may further include a handle for providing power, and the handle may include a square shaft penetrating the square hole, and the driving force may be provided to the gear 500 by rotating the handle. In other embodiments, the gear 500 may also be engaged with a gear of the motor and used to obtain power from the motor as the driving force, and in still other embodiments, the gear 500 may also be drivingly connected to the rotatable lock cylinder and powered by rotation of the lock cylinder. In this embodiment, the gear 500 is rotatably disposed on the bottom case 920 and engaged with the second toothed disc 630, so as to drive the second toothed disc 630 to rotate. The rotation direction of the driving force acts on the gear 500, and since the gear 500 is engaged with the second toothed disc 630, the rotation direction of the gear 500 is opposite to that of the second toothed disc 630. The driving force drives the gear 500 to rotate and drives the second toothed disc 630 to rotate, so as to enable the second toothed disc 630 to rotate in the correct rotation direction. In other embodiments, the latch 1000 may also include a worm, and the second toothed disk 630 may also be a worm gear that mates with and is drivingly connected to the worm. The turbine worm structure can also realize power transmission and direction change, and is not limited herein.

In some embodiments, the tongue 810 may be provided with a first locking portion 816, where the first locking portion 816 is configured to limit rotation of the tongue 810, so as to implement a temporary door locking function. The lock 1000 may further include a locking member 500, and the locking member 500 is provided with a second locking portion 510. The first locking portion 816 and the second locking portion 510 may be some structures that can be selectively connected or separated, such as a mechanical buckle, etc., which is not limited herein. When the first locking portion 816 is connected to the second locking portion 510, the second locking portion 510 can restrict rotation of the tongue 810, thereby maintaining the pushing plane 812 of the tongue 810 in a state perpendicular to the guide plate 910.

The lock 1000 proposed in this embodiment is based on the following principle:

In the lock 1000 according to the present embodiment, the reset component 701 may be disposed in the accommodating cavity 930 and slide between the first position and the second position, and the reset pushing seat 701 is provided with a bump sliding along the chute, and the bump plays a guiding role in sliding of the reset pushing seat 701. When the reset pushing seat 701 is driven by the reset element 610 and moves from the second position to the first position, the driving force drives the gear 500 to rotate, the gear 500 drives the second toothed disc 630 to rotate, and one end of the arc-shaped groove 6311 on the second toothed disc 630 abuts against the first transmission portion 621 disposed on the first toothed disc 620, so that the speed at which the reset pushing seat 701 pushes the tongue 810 to reset is related to the rotation speed of the driving element 600. When the reset pushing seat 701 is located at the first position, the reset pushing seat 701 abuts against the tongue 810, and the second limiting portion 740 on the reset pushing seat 701 is embedded into the first limiting portion 815 on the tongue 810, so that the tongue 810 extends out of the lock hole 911, and the pushing plane 812 of the tongue 810 is kept perpendicular to the guide plate 910. When the inclined surface 811 of the tongue 810 contacts with the side plate 2000 or the door frame, the tongue 810 can push the reset pushing seat 701 to move, the reset pushing seat 701 drives the first fluted disc 620 to rotate, and the first transmission part 621 can slide along the arc-shaped groove 6311 at this time, and does not drive the second fluted disc 630 and apply force to the power source, so as to protect the power source. According to the lock 1000 provided by the application, the tongue 810 is arranged in the lock hole and is abutted against the reset pushing seat 701, and the driving piece 600 is in transmission connection with the reset pushing seat 701 and can acquire driving force, so that the reset pushing seat 701 can be slowly driven to push the tongue 810 to extend by controlling the driving force, and noise generated by collision between parts when the tongue 810 extends too quickly is avoided. Meanwhile, the reset pushing seat 701 can be separated from the tongue 810, and when the reset pushing seat 701 is separated from the tongue 810, the tongue 810 is pushed and retracted, and the resistance is smaller, so that the noise generated when pushing the tongue 810 is smaller.

The above embodiments are only for illustrating the technical solution of the present application, and are not limiting thereof; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present application, and they should be included in the protection scope of the present application.
