With the high-speed development of the intelligent home industry, the intelligent door lock is used as an intelligent product at the home entrance end, and plays an important role in the linkage effect of the intelligent home. Meanwhile, in the daily high-frequency use process of the intelligent door lock, the uncertainty of installation scenes such as a door frame and the like requires that the stability of the door lock is high. The lock body is used as a core component of the door lock, and the virtual position control, the mechanical stability, the installation convenience and the like of the lock body play a key role in the overall performance of the door lock. The lock tongue of the existing lock body comprises a lock tongue and an anti-lock tongue, wherein the anti-lock tongue is used for locking the door plate and the door frame, and the lock tongue can be used for temporarily locking the door plate and the door frame. But current tool to lock, after locking temporarily and when opening the door from the outdoor, need the user to withdraw the spring bolt, increased user's operation burden like this, the unblock spring bolt need be in retrieving the spring bolt keyhole simultaneously, and the great drive power of needs like this can increase user's operation burden, or increase intelligent lock power device's energy consumption, is unfavorable for promoting intelligent lock duration. The application provides a tool to lock and lock to improve above-mentioned problem.

Referring to fig. 1, the present embodiment provides a door lock 3000, which includes a lock 1000 and a lock panel (not shown), the lock panel may include a driving assembly, a handle, etc., and the lock 1000 is electrically or drivingly connected to the lock panel. The lockset is fitted with the side plate 2000 to be installed on the door and the doorframe. As an embodiment, the lock 1000 may be disposed on the same horizontal plane as the side plate 2000. In other embodiments, the lock 1000 can be disposed on the same vertical position as the side plate 2000, which is not limited herein.

The lock 1000 includes a housing 900, a locking bolt 800, and a locking member 700. The case 900 includes a bottom case 920 and a guide plate 910 mounted on the bottom case 920, and specifically, the guide plate 910 is mounted on one side edge of the bottom case 920, and is opposite to the side plate 2000 when mounted, and the other edge of the bottom case 920 is bent, so that the bottom case 920 and the guide plate 910 enclose an accommodating cavity in which the latch tongue 800 and the locking member 700 are located. The guide plate 910 is provided with a locking hole 911, and the locking hole 911 penetrates through the guide plate 910.

The lock tongue 800 can be telescopically arranged along the axial direction of the lock hole 911, and selectively extends out of the lock hole 911 or retracts into the accommodating cavity at least partially. The side plate 2000 is provided with a latch hole 2001, the latch hole 2001 is disposed corresponding to the lock hole 911, and the latch 800 may extend out of the lock hole 911 and be inserted into the latch hole 2001, so that the door lock 3000 is locked. The locking member 700 is used to lock the latch bolt 800. In some embodiments, the locking hole 911 may be substantially square and substantially identical to the outer contour of the locking tongue 800, so that when the locking tongue 800 is disposed in the locking hole 911, the locking tongue 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 provided in other shapes, which is not limited herein. In some embodiments, the guide plate 910 may further include an anti-lock hole 912. The lock 1000 may further include a plurality of anti-lock bolts (not shown), which may be linked together to extend into or out of the anti-lock hole 912 and cause the lock 1000 to be locked.

Referring to fig. 2, the latch 800 includes a tongue 810 extending along an axial direction of the lock hole 911 and a connecting post 820. The connecting column 820 is also arranged along the axial direction of the lock hole 911 and is hinged with one end of the tongue body 810, so that the tongue body 810 can rotate relative to the connecting column 820. Specifically, the end of the connecting column 820 close to the tongue 810 is provided with a pin hole, the tongue 810 is hinged to the pin hole through the pivot 816, and the axial direction of the pin hole is substantially perpendicular to the axial direction of the locking hole 911 and substantially perpendicular to the extending direction of the connecting column 820.

An inclined plane 811 is arranged at one end of the tongue body 810 far away from the connecting column 820, and in an initial state of the tongue body 810, the inclined plane 811 and the axis of the lock hole 911 form an included angle. The inclined surface 811 can extend out or retract into the lock hole 911 as the tongue 810 extends and retracts. When the door panel rotates around the door frame, the side plate 2000 abuts against the inclined surface 811 and slides along the inclined surface 811, and generates a component force to the tongue body 810 along the axial direction of the lock hole 911, so as to push the tongue body 810 to extend into the lock hole 911 along the opening. In some embodiments, a push plane 812 is also disposed on the side of the tongue 810 opposite the inclined plane 811. In the initial state of the tongue 810, the push plane 812 may be substantially parallel to the axis of the locking hole 911.

Referring to fig. 3, when the tongue 810 is inserted into the latch hole 2001 of the side plate 2000, since the tongue 810 can rotate relative to the connecting column 820, when the user pushes the door panel, the side wall of the side plate 2000 forming the latch hole 2001 can abut against the push plane 812, and a force F perpendicular to the push plane 812 is provided to the push plane 812, so that the tongue 810 is pushed to rotate, and a certain angle is formed between the push plane 812 and the axis of the latch hole 2001. As the user continues to push the door panel, the door frame can slide along the inclined push plane 812, and at the same time, a component force in the axial direction of the locking hole 911 is applied to the tongue body 810, so that the tongue body 810 is retracted into the locking hole 911. Therefore, the user can directly open the door by pushing the door plate.

The tongue 810 may have an excessive noise problem when it comes into contact with the side plate 2000. Therefore, in some embodiments, referring to fig. 3, a noise reduction member 813 may be further disposed on the tongue 810. The noise reducer 813 may be a separate piece located along the ramp 811 and push flat 812. Illustratively, the tongue 810 is provided with a mounting groove 814, the mounting groove 814 is continuously disposed between the inclined surface 811 and the flat pushing surface 813, the noise reducing member 813 is embedded in the mounting groove 814, and the noise reducing member 813 may slightly protrude from the inclined surface 811 and the flat pushing surface 813. When the push flat 812 or the inclined surface 811 contacts the side plate 2000, the noise reducer 813 first abuts the side plate 2000. The noise reducer 813 may be made of a material with a certain impact resistance, such as a rigid plastic, so that when the side plate 2000 abuts against the noise reducer 813, a part of the generated noise can be reduced.

Different doors have different rotational directions, and the orientation of the push plane 812 and the bevel 811 need to be changed. Therefore, in some embodiments, referring to fig. 3, fig. 4 and fig. 5, the user can pull the latch 800 out of the lock hole 911 and rotate it for one circle to improve the above problem. For example, the door lock 1000 may further include a tongue base 600 and a limiting member 500, where the tongue base 600 may be a part assembled on the bottom case 920, or may be integrally formed with the bottom case 920, which is not limited herein. The tongue base 600 is provided with a first through hole 610, a certain distance is formed between the tongue base 600 and the guide plate 910, and the first through hole 610 is arranged opposite to the locking hole 911. A clamping part 821 is arranged at one end of the connecting column 820 far away from the tongue body 810, and the diameter of the clamping part 821 is smaller than that of the first through hole 610. The limiting member 500 can slide along the tongue 600 and selectively abut against the connecting post 820 to limit the clamping portion 821 on the connecting post 820 from passing through the first through hole 610. Thus, when the tongue body 810 needs to be rotated, the clamping portion 821 can pass through the first through hole 610 only by separating the limiting member 500 from the connecting column 820, so that the tongue body 810 can completely extend out of the lock hole 911 and rotate.

In the using process of the tongue body 810, after the user pulls out the tongue body 810, there may be a problem that it is inconvenient to withdraw the tongue body 810 into the locking hole 911 for resetting. In some embodiments, the locking bolt 800 may further include a reset 840. Illustratively, the reset member 840 may include a reset push socket 830, a spring 841, and a blocking plate 842. The reset pushing base 830 may be disposed between the tongue 810 and the tongue base 600, abut against the tongue 810 and may slide along the bottom case 920, so as to achieve the function of pushing the tongue 810 to extend for resetting. In this embodiment, the reset pushing seat 830 is provided with a second through hole 831, the mounting post 820 is inserted into the second through hole 831, and one end of the reset pushing seat 830 abuts against the tongue 810. The blocking plate 842 may be provided with a third through hole 8421, and is sleeved on the connecting column 820. The blocking piece 842 can be located between the reset pushing seat 830 and the tongue seat 600, and the diameter of the third through hole 8421 can be smaller than the diameter of the clamping portion 821 on the connecting column 820, so that the connecting column 820 can slide in the third through hole 8421 until the clamping portion 821 abuts against the blocking piece 842. The spring 841 may be disposed between the blocking piece 842 and the reset push seat 830. When the user pulls the tongue 810 out of the locking hole 911, the latch portion 821 abuts against the stopper 842 and drives the stopper 842 to move toward the locking hole 911, and at this time, the stopper 911 compresses the spring 841. After the user completes the rotation process of the tongue body 810, the spring 841 can push the blocking piece 842 to move, and the blocking piece 842 pulls the connecting post 820 to drive the tongue body 810 back into the locking hole 911.

The door lock 2000 needs to have a locking function so that the door panel and the door frame cannot rotate relative to each other when the door lock is locked. Referring to fig. 6, 7 and 8, in some embodiments, the tongue 810 further includes a first limiting portion 815, the locking member further includes a second limiting portion 710, and the first limiting portion 815 is connected to the second limiting portion 710 to limit the rotation of the tongue 810 relative to the connecting post 820. To achieve the locking function.

The locking member 700 can be selectively located at the first position 10 and the second position 20, and when the locking member 700 is located at the first position 10, the second position-limiting portion 710 is connected to the first position-limiting portion 815, so as to achieve the locking function of the door lock 3000. When the locking member 700 is located at the second position 20, the second position-limiting portion 710 is separated from the first position-limiting portion 815, so as to achieve the unlocking function. In some embodiments, the locking member 700 may be slidably disposed on the bottom case 920 and selectively located at the first position 10 or the second position 20 during the sliding process. In other embodiments, the locking member 700 may also be rotatably disposed on the bottom case 920, and during the rotation process, the locking member may also be selectively located at the first position 10 and the second position 20.

The first position-limiting portion 815 and the second position-limiting portion 710 are mutually matched. Illustratively, the first limiting portion 815 is one of the first sliding slot 8151 and a limiting protrusion, the second limiting portion 710 is the other of the first sliding slot 8151 and the limiting protrusion, the first sliding slot 8151 extends along an axial direction of the locking hole 911, and the second limiting portion 710 is embedded in the first sliding slot 8151 when the locking member 700 is located at the first position. In the embodiment, the first position-limiting portion 815 is a first sliding slot 8151 disposed on the tongue 810. When the locking member 700 is located at the first position, the second position-limiting portion 710 can be inserted into the first sliding slot 8151, so that the first position-limiting portion 815 is locked to the second position-limiting portion 710. Specifically, the first sliding slot 8151 has a certain length, and the width of the second limiting portion 710 is substantially the same as that of the first sliding slot 8151. When the second position-limiting portion 710 is inserted into the first sliding slot 8151, the two side walls forming the first sliding slot 8151 abut against the two sides of the second position-limiting portion 710, so that the tongue 810 cannot rotate.

In other embodiments, the first position-limiting portion 815 and the second position-limiting portion 710 may also be devices that cooperate with each other. For example, the first position-limiting portion 815 may be a magnet, and the second position-limiting portion 710 may be an electromagnet, and the electromagnet may be controlled to generate a magnetic force to interact with the magnet, thereby locking or unlocking the electromagnet and the magnet. In some embodiments, the first position-limiting portion 815 and the second position-limiting portion 710 may be another device that can be controlled to lock or separate, such as an electric buckle, and the like, which is not limited herein.

The lock 700 may have a problem of deviation of the moving direction during the selective switching between the first position 10 and the second position 20. Therefore, in some embodiments, a second sliding groove 921 may be further formed on the bottom case 920, and a sliding portion (not shown) may be further formed on the locking member 700, and the sliding portion is embedded in the second sliding groove 921, so that the locking member 700 can be slidably disposed on the second sliding groove 921. In some embodiments, the second slide slot 921 can be a slot extending along a straight line, and the first position 10 and the second position 20 are respectively located at two ends of the second slide slot 921, so that the locking member 700 can move linearly between the first position 10 and the second position 20. In another embodiment, the second sliding slot 921 can be an arc-shaped slot, and the first position 10 and the second position 20 are respectively located at two ends of the arc-shaped slot, so that the locking member 700 can slide along an arc between the first position 10 and the second position 20.

In the process of embedding the second limiting portion 710 into the first sliding slot 8151, since the locking member 700 is slidably disposed in the second sliding slot 921, when the tongue 810 receives an external acting force, the sidewall of the first limiting portion 815 located at one end of the first sliding slot 8151 pushes the second limiting portion 710 along the axial direction of the first sliding slot locking hole 911, so that the locking member 700 slides along the second sliding slot 921. Therefore, in some embodiments, the extending direction of the first slide slot 8151 and the extending direction of the second slide slot 921 may be perpendicular to each other. In this way, the force of the locking member 700 along the first sliding slot 8151 acts perpendicularly on the longitudinal side wall of the second sliding slot 921. The locking member 70 is not subjected to a force in a sliding direction of the second slide slot 921, thereby overcoming a problem that the locking member 700 slides along the second slide slot 921 when the first stopper 815 is locked to the second stopper 710.

During the movement of the locking member 700 between the first position 10 and the second position 20, a certain amount of power is required to drive the locking member 700. Therefore, in some embodiments, referring to fig. 5 and fig. 6, the lock body 1000 may further include a driving portion 400. The driving part 400 is used for driving the locking member 700 to move, so that the locking member 700 is selectively located at the first position 10 or the second position 20. In some embodiments, the driving part 400 may also be used to drive the reset push socket 830 to move. In some embodiments, the driving part 400 may be a driving structure in the lock body, and a device for providing a driving force by a power device such as a driving motor. In other embodiments, the driving portion 400 may also be a lock cylinder or the like, and a user may insert a key to screw the lock cylinder, so as to drive the locking member 700, which is not limited herein.

The driving part 700 is in transmission connection with the locking member 400, thereby achieving the purpose of driving the locking member 700. In some embodiments, the driving part 400 may include an unlocking block 410, and the unlocking block 410 is used for being in transmission connection with the locking member 700 and driving the locking member 700 to move. The unlocking block 410 can be rotatably disposed on the bottom case 920, and the unlocking block 410 has a connecting portion 411 in transmission fit with the locking member 700. When the unlocking block 410 rotates, the connecting portion 411 drives the locking member 700 to be selectively located at the first position 10 or the second position 20.

In this embodiment, since the locking member 700 slides linearly relative to the bottom case 920 and the unlocking block 410 rotates relative to the bottom case 920, the unlocking block 410 and the locking member 700 also rotate relatively. Illustratively, the locking member 700 is provided with at least one connecting groove 720, and the connecting portion 411 may be provided in a plurality of rows and in one-to-one correspondence with the at least one connecting groove 720. Each connecting portion 411 is embedded in one connecting groove 720. Thus, when the unlocking block 410 is rotated, the connection portion 411 may abut against a sidewall forming the connection groove 720 and push the locking member 700 to rotate. In other embodiments, the locking member 700 can also slide along the second sliding slot 920, and at this time, the second sliding slot 920 can be disposed along the arc of the rotation track of the connecting portion, so that the locking member 700 can be directly and fixedly disposed on the connecting portion 411.

One end of the unlocking block 410, which is far away from the connecting part 411, is provided with a power part 412, and the power part 412 is used for receiving external power. In some embodiments, a rotation hole 413 is formed between the power part 412 and the connection part 411, and accordingly, a rotation shaft engaged with the rotation hole 413 is formed on the bottom case 920. The rotation shaft may be integrally formed with the bottom case 920, or may be mounted on the bottom case 920, which is not limited herein. The rotating hole 413 is sleeved on the rotating shaft, so that the unlocking block 410 can rotate on the bottom case 920. External power is applied to the power part 412 to rotate the unlocking block 410, so that the connecting part 411 rotates. The external power may be from a driving motor or a telescopic device disposed in the lock 1000, or from a user twisting a key engaged with the lock 1000, which is not limited herein.

The unlocking block 410 drives the locking member 700 to move, so that the tongue 810 cannot rotate, and thus the locking function of the lock 1000 can be realized. However, the locking member 700 may be separated from the tongue 810 by gravity. Therefore, in this embodiment, the driving part 400 further includes an elastic member 420, and the elastic member 420 drives the unlocking block 410 to rotate, so that the locking member 700 can be connected with the tongue 810. Exemplarily, the elastic member 420 is disposed on the bottom case 920 and is in transmission connection with the unlocking block 410, the elastic member 420 may be a torsion spring sleeved on the rotation shaft, two ends of the torsion spring, which can move relatively, are respectively and fixedly disposed on the unlocking block 410 and the bottom case 920, and when the unlocking block 410 rotates under the action of external power, the torsion spring deforms. When the lock 1000 needs to be locked, the external power no longer drives the unlocking block 410, and the torsion spring drives the unlocking block 410 to rotate in the direction opposite to the rotation direction during unlocking under the action of the restoring force, so that the second limiting portion 710 is connected with the first limiting portion 815, and the connection between the locking member 700 and the tongue 810 is maintained.

The lock 1000 that this application proposes uses the principle as follows:

in the lock 1000 of the present application, the tongue 810 is extended and retracted in the tongue hole 911, and is selectively inserted into the tongue hole 2001 of the side plate 2000, so as to limit the relative rotation between the door plate and the door frame. The lock 1000 can be locked by locking the tongue 810. The tongue 810 is provided with a first stopper 815, the bottom case 920 is provided with a locking member 700 capable of sliding along the bottom case 920, and the locking member 700 is provided with a first stopper 710. The tongue 810 can be unlocked or locked by selectively connecting or separating the first position-limiting part 710 and the second position-limiting part 815. An unlocking block 410 is further provided on the bottom chassis 920, and the unlocking block 410 may drive the locking member 700 to move between the first position 10 and the second position 20 by rotating the unlocking block 410. An elastic member 420 is further provided at the unlocking block 410, and the elastic member 420 is used to assist unlocking. According to the lock 1000 provided by the application, when the locking piece 700 locks the bolt 810, the bolt 810 cannot rotate, so that the locking function is realized. Therefore, when unlocking, only the locking piece 700 needs to be separated from the bolt 810, and the bolt 810 can be unlocked only after being driven to retract by the driving force, so that the unlocking is more convenient and labor-saving than the unlocking by driving the bolt by using a smaller driving force to drive the locking piece 700 to move.

The above embodiments are only for illustrating the technical solutions of the present application, and not for limiting the same; although the present 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 solutions described in the foregoing embodiments may be modified or some technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the spirit and scope of the embodiments of the present application and are intended to be included within the scope of the present application.
