Description

A lock structure

Technical Field

The invention relates to a lock structure.

Background technique

At present, door locks with electric door opening and closing functions generally include a front lock body, a rear lock body, a connecting rod, and an electric clutch mechanism, wherein one end of the connecting rod is fixed to the rear lock body, and the other end of the connecting rod extends into the front lock body, and the electric clutch mechanism can drive the connecting rod and the front lock body to connect or separate to realize door opening and closing.

In the prior art, general electric door locks also need to be equipped with a mechanical lock core and a battery to provide power to the electric clutch mechanism. Since the conventional electric clutch structure and the internal layout structure of the front lock body are relatively complex and the internal space of the front lock body is relatively small, the electric clutch mechanism is generally installed in the front lock body, and the battery and the battery compartment are arranged in the rear lock body. For this reason, it is also necessary to set wires connecting the battery and the electric clutch mechanism between the front lock body and the rear lock body, which makes the production and assembly of the door lock very inconvenient.

In addition, the general electric clutch mechanism uses an electric push rod to push the clutch to open and close the door. The motor needs to rotate more times, consumes more energy, and has a slow response speed. In addition, when the electric push rod pushes the clutch to move, it is easy to get stuck and produce a lot of noise.

Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

1 to 7 , a lock structure according to an embodiment of the present invention comprises: a connecting rod 100, a connecting member 110 is provided at one end of the connecting rod 100, and the connecting member 110 is provided with a first connecting portion 111 and a second connecting portion 112 distributed circumferentially around the axial direction of the connecting rod 100; a front lock body 200, which is movably connected to the connecting member 110 and can rotate relative to the connecting rod 100, and a cavity 210 is provided in the front lock body 200; a mechanical lock core 300, which is disposed in the cavity 210, and an output end of the mechanical lock core 300 is connected to a first clutch member 410 that can be telescopically moved in a direction parallel to the connecting rod 100 to be combined with or separated from the first connecting portion 111; an electric drive device 500, which is disposed in the cavity 210, and an output end of the electric drive device 500 is connected to a second clutch member 420 that can be telescopically moved in a direction parallel to the connecting rod 100 to be combined with or separated from the second connecting portion 112; and a battery 600, which is disposed in the cavity 210 and connected to the electric drive device 500.

The above lock structure sets the mechanical lock core 300, the electric drive device 500 and the battery 600 in the cavity 210 of the front lock body 200, eliminating the need to connect wires between the front lock body 200 and the rear lock body, simplifying the production and assembly process, and reducing costs. The first clutch 410 driven by the mechanical lock core 300 and the second clutch 420 driven by the electric drive device 500 both telescopically move in a direction parallel to the connecting rod 100, and the first connecting portion 111 corresponding to the first clutch 410 and the second connecting portion 112 corresponding to the second clutch 420 are arranged on the connecting member 110 around the circumference of the connecting rod 100, so that the direction of the clutch movement is along the length direction of the connecting rod 100, avoiding a significant increase in the radial size of the front lock body 200, and the structure is compact in layout, and the production and assembly efficiency is high.

5 and 6, in some embodiments of the present invention, the electric drive device 500 includes a motor 510 fixed in the cavity 210, a rotating block 520 connected to the output shaft of the motor 510, and a moving block 530 that can reciprocate along the output shaft of the motor 510, the second clutch 420 is arranged on the moving block 530, and a magnetic component 700 is arranged between the rotating block 520 and the moving block 530. When the motor 510 drives the rotating block 520 to rotate, the moving block 530 can be driven to approach or move away from the rotating block 520 through the magnetic component 700, thereby driving the second clutch 420 to be combined with or separated from the second connecting portion 112. Among them, a guide groove 531 is arranged on the moving block 530, and accordingly, the inner shell 202 is provided with a guide strip matching the guide groove 531 to ensure that the moving block 530 can only move along the direction of the output shaft of the motor 511. Of course, in other embodiments, the electric drive device 500 may also adopt a conventional electric push rod structure, and utilize the electric push rod to push the second clutch member 420 to be combined with the second connecting portion 112 .

It should be noted that when the motor 510 drives the rotating block 520 to rotate a certain angle, the magnetic assembly 700 located between the moving block 530 and the rotating block 520 can generate a magnetic force of mutual attraction or mutual repulsion to make the moving block 530 approach or move away from the rotating block 520, thereby driving the second clutch member 420 and the second connecting portion 112 to be combined or separated, thereby connecting or separating the front lock body 200 and the connecting rod 100. Compared with the traditional method of using an electric push rod, the use of the magnetic assembly 700 is simpler, has lower cost, and is less difficult to assemble. Moreover, the clutch action can be achieved by only rotating the motor 510 at a smaller angle, and the response rate is faster.

Referring to FIG. 6 , in some embodiments of the present invention, the rotating block 520 and the moving block 530 each have a first magnet 710 and a second magnet 720 distributed circumferentially around the output shaft of the motor 510, the magnetic poles of the first magnet 710 and the second magnet 720 at the ends close to each other are opposite, and the two first magnets 710 and the two second magnets 720 together constitute a magnetic assembly 700. Specifically, on the end surface of the rotating block 520 facing the moving block 530, the magnetic poles of the first magnet 710 and the second magnet 720 on the rotating block 520 are respectively the N pole and the S pole, and on the end surface of the moving block 530 facing the rotating block 520, the magnetic poles of the first magnet 710 and the second magnet 720 on the moving block 530 are respectively the N pole and the S pole, when the two first magnets 710 are aligned, the two second magnets 720 are also aligned, thereby generating a mutual repulsion effect, so that the second clutch 420 on the moving block 530 moves toward the second connecting portion 112 and combines; when the two first magnets 710 are respectively aligned with the two second magnets 720, a mutual attraction effect is generated, so that the second clutch 420 on the moving block 530 moves away from the second connecting portion 112 and separates. The above magnetic assembly 700 has a simple and ingenious structure, so that the electric drive device 500 has a fast action response and low noise.

Referring to FIG. 2 and FIG. 4 , in some embodiments of the present invention, the front lock body 200 includes an inner shell 202 and an outer shell 201 fixedly sleeved on the outer surface of the inner shell 202. The inner space of the inner shell 202 constitutes a cavity 210. A rotation space for the connecting member 110 to rotate relative to each other is defined between the inner shell 202 and the outer shell 201. The first clutch member 410 and the second clutch member 420 are both arranged in the inner shell 202 and can extend into the rotation space. The connecting member 110 is located in the rotation space between the inner shell 202 and the outer shell 201, so that the whole formed by the inner shell 202 and the outer shell 201 can rotate relative to the connecting rod 100 without occupying the volume in the cavity 210, so that the cavity 210 can be fully used to accommodate the mechanical lock cylinder 300, the electric drive device 500 and the battery 600. In addition, in some embodiments, the front lock body 200 includes an inner shell 202 and an outer shell 201 , wherein the outer shell 201 is fixed to the door panel, and the inner shell 202 and the connecting member 110 can rotate relative to the outer shell 201 .

Referring to FIG. 2 and FIG. 4 , in some embodiments of the present invention, the inner shell 202 and the outer shell 201 are both cylindrical and define a cylindrical cavity 210 and a rotation space, and the battery 600, the electric drive device 500, and the mechanical lock core 300 are distributed in the cavity 210 around the axial direction of the connecting rod 100. Among them, the connecting member 110 is a disc-shaped thin plate member, which is conducive to reducing the size of the rotation space along the length direction of the connecting rod 100 and improving the structural compactness of the front lock body 200. Since the first connecting portion 111 and the second connecting portion 112 are distributed in the connecting member 110 around the axial direction of the connecting rod 100, correspondingly, the electric drive device 500 and the mechanical lock core 300 are distributed in the cavity 210 around the axial direction of the connecting rod 100, so that the two parts of the mechanical lock core 300 and the first connecting portion 111, the electric drive device 500 and the second connecting portion 112 are independent of each other and do not interfere with each other, and at the same time, the space of the cavity 210 is fully utilized.

Referring to Fig. 4, in some embodiments of the present invention, both the outer shell 201 and the inner shell 202 have openings facing forward and connected to the cavity 210, and a cover plate 203 capable of closing the cavity 210 is provided at the opening of the outer shell 201, and a cover recognition control module 800 electrically connected to the electric drive device 500 is provided on the cover plate 203. It can be understood that the control part of the cover recognition control module 800 can be stored in the clearance of the cavity 210, so as to further optimize the layout of the lock structure.

Referring to FIG. 4 , in some embodiments of the present invention, in order to broaden the use of unlocking, the cover recognition control module 800 includes a fingerprint module 810 disposed in the middle of the cover plate 203 and a password input disk 820 disposed around the periphery of the fingerprint module 810. The small volume space of the cover plate 203 is used to integrate the two unlocking methods of fingerprint and password, which is very convenient to use. Of course, in other embodiments, the cover recognition control module 800 can also be replaced by a door access recognition device or a mobile terminal remotely controlled by an APP to open the door.

In some embodiments of the present invention, the connecting member 110 is in the shape of a disk, the first connecting portion 111 and the second connecting portion 112 are respectively provided at the outer peripheral edge of the connecting member 110 as a first notch groove and a second notch groove, the first clutch member 410 is a first driving column extending from the inner shell 202 to be inserted into the first notch groove or received in the inner shell 202 to be separated from the first notch groove, and the second clutch member 420 is a second driving column extending from the inner shell 202 to be inserted into the second notch groove or received in the inner shell 202 to be separated from the second notch groove. Specifically, the first notch groove, the second notch groove and the connecting member 110 are an integrated structure, which is conducive to simplifying the processing and manufacturing process, and the clutch method of using the first driving column to move in and out of the first notch groove relative to the inner shell 202 and the second driving column to move in and out of the second notch groove relative to the inner shell 202 is very simple, and the production and processing difficulty is also low. In addition, it should be noted that when a reset spring is provided between the first driving column and the inner shell 202 and between the second driving column and the inner shell 202, the first driving column or the second driving column can be reset after being extended.

Referring to FIG. 1 and FIG. 2 , in some embodiments of the present invention, in order to extend the service life of the lock structure, a charging module 900 electrically connected to the battery 600 is provided inside the inner shell 202, and the charging module 900 has a charging interface 910 extending along the sides of the inner shell 202 and the outer shell 201. The battery 600 can be charged by inserting the power cord into the charging socket, thereby increasing the battery life of the electric drive device 500. In some embodiments, the key hole of the mechanical lock core 300 also extends along the sides of the inner shell 202 and the outer shell 201. The mechanical lock core 300 is used as an uncommon way to open the door, and the above-mentioned installation position is conducive to avoiding the key hole occupying part of the position of the cover plate 203. Referring to Fig. 7, in this embodiment, the mechanical lock core 300 is a telescopic lock core, the output end of the telescopic lock core is connected to the push block 310, the push block 310 is provided with a driving inclined surface 311, the end of the first driving column away from the first notch groove abuts against the driving inclined surface 311, when the output end of the telescopic lock core is extended, the driving inclined surface 311 can drive the first driving column to be inserted into the first notch groove. It should be noted that in other embodiments, the following manner can also be adopted: the mechanical lock core 300 is a telescopic lock core, and the output end of the telescopic lock core directly drives the first clutch member 410 to extend and move toward the first connecting portion 111.

Referring to FIG. 3 , in some embodiments of the present invention, a neck portion 204 is provided on the end surface of the housing 201 for the connecting rod 100 to be movably inserted, a mounting plate 205 for fixing to the door panel is sleeved on the outside of the neck portion 204, the neck portion 204 can rotate relative to the mounting plate 205, and a rotation angle reset mechanism 920 for limiting the rotation angle of the front lock body 200 and driving the front lock body 200 to rotate and reset is provided between the neck portion 204 and the mounting plate 205. It can be understood that the mounting plate 205 is fixed to the door panel, and in the unlocked state, the connecting rod 100 and the front lock body 200 can rotate relative to the mounting plate 205 as a whole, thereby opening the door lock. In this embodiment, the angle reset mechanism 920 includes a rotation limit block 921 fixedly connected to the shaft neck 204, and two angle limit blocks 922 are provided on the mounting plate 205 and are distributed axially around the connecting rod 100. The rotation limit block 921 is located between the two angle limit blocks 922. A torsion spring 923 is passed through the shaft neck 204, and one end of the torsion spring 923 contacts the mounting plate 205, and the other end of the torsion spring 923 contacts the rotation limit block 921. When the first clutch 410 and the first connecting portion 111 are combined, or the second clutch 420 and the second connecting portion 112 are combined, the front lock body 200 and the connecting rod 100 can rotate together relative to the mounting plate 205. When rotated to the unlocking position, the rotation limit block 921 abuts against one of the angle limit blocks 922. When the hand is released, the front lock body 200 rotates and resets under the action of the torsion spring 923.
