Description

Technical Field

[0001] This invention relates to the field of lock technology, and in particular to a lock that is opened by a motor-driven turntable. Background Technology

[0002] As we all know, locks are devices that serve a sealing function, including locks, keys, and their accessories. They are generally defined as "sealing devices that can only be opened with a key." Besides keys, locks can also be opened using light, electricity, magnetism, sound, and fingerprint signals. Therefore, locks are widely used in daily life. When used for small everyday items, they are often designed as miniature locks, such as fingerprint-activated handbag locks.

[0003] Currently, existing small locks need to be simple in structure, easy to lock, and easy to unlock. However, existing small locks have a common problem: unstable locking. Under the influence of external forces such as shaking, dropping, prying, or twisting, they may unlock spontaneously. For example, a fingerprint lock for a handbag disclosed in patent number 201921432434.3, although it meets the design requirements of a small lock—simple in structure, easy to lock, and easy to unlock—relies entirely on a spring pressing outward against the bolt to keep it locked. Once the spring retracts under external force, the bolt will disengage, thus unlocking the lock. This is clearly not a stable locking mechanism and there is a possibility of abnormal unlocking.

[0004] Therefore, it is necessary to optimize the structure of existing miniature locks. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a lock that is opened by a motor-driven turntable.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lock opened by a motor-driven turntable includes a lock cover and a base. The bottom surface of the lock cover has a latch, which consists of a lock bar and a lock head located at the top of the lock bar. The lock head is non-circular, and its length or width is greater than the diameter of the lock bar. The base houses a rotatable turntable, a circuit board, and a battery and motor electrically connected to the circuit board. The turntable has an insertion port with a shape corresponding to the lock head at the position opposite the latch. The back of the turntable has a top block that allows movement only in a vertical direction. The top of the top block can pass through the insertion port. A first spring is located at the bottom of the top block. A column is located on the side of the back of the turntable, and a second spring is connected to the column. The other end of the second spring is laterally connected to the inner wall of the base. A gear is located on the rotating head of the motor. The base holds an unlocking block that can move laterally, and the unlocking block has a rack surface on which the gear meshes.

[0008] Under the action of the first spring, the top block is constantly pressed against the turntable;

[0009] Under the action of the second spring, the turntable can rotate, and the column rod always tends to press against the unlocking block.

[0010] Preferably, the back of the turntable is provided with a movable cavity, which is connected to the insertion port, and the top of the top block is placed inside the movable cavity.

[0011] Preferably, the base has a circular groove inside, the turntable is placed in the circular groove, and the case of the base has a lock hole with a shape corresponding to the insertion port relative to the circular groove.

[0012] Preferably, the top block is provided with limit blocks at both ends, and the base is provided with a vertically opened sliding groove on the side of the circular groove. The limit blocks are respectively placed in the corresponding sliding grooves, so that the top block can only move in the vertical direction.

[0013] Preferably, the base is provided with a biometric identification module, which is electrically connected to the circuit board.

[0014] Preferably, the biometric identification module is a fingerprint identification module.

[0015] By adopting the above-mentioned solution, the present invention incorporates a turntable structure, allowing both locking and unlocking to be controlled by the rotation of the turntable. This makes locking more stable, and the turntable is less likely to generate rotational force during knocking and vibration, ensuring the security of the lock and preventing it from unlocking naturally during knocking and vibration. At the same time, the characteristic of the bolt being able to pop out after the turntable is rotated and aligned makes the unlocking operation more convenient. Attached Figure Description

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection. They can refer to a direct connection or an indirect connection through an intermediate medium, and they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0022] like Figures 1 to 3As shown, this embodiment provides a lock that opens via a motor-driven turntable, including a lock cover 1 and a base 2 (the lock cover 1 is mounted on one object, and the base is mounted on another object; locking involves locking these two objects). The bottom surface of the lock cover 1 is provided with a latch 3, which consists of a locking rod 31 and a lock head 32 located at the top of the locking rod 31. The lock head 32 is not perfectly circular; that is, it cannot be designed as a circle, but can be elliptical or rectangular. The length or width of the lock head 32 is greater than the diameter of the locking rod 31. The base 2 houses a rotatable turntable 4, a circuit board 5, and a battery 6 and a motor 7 electrically connected to the circuit board 5. The turntable 4 faces... The latch 3 is provided with an insertion port 41 whose shape corresponds to the lock head 32. The back of the turntable 4 is provided with a top block 8 that can only move in the vertical direction. The top of the top block 8 can be inserted into the insertion port 41. A first spring 81 is provided at the bottom of the top block 8. A column rod 42 is provided on the side of the back of the turntable 4. A second spring 43 is connected to the column rod 42. The other end of the second spring 43 is horizontally connected to the inner wall of the base 2. A gear 71 is provided on the rotating head of the motor 7. An unlocking block 72 that can move horizontally is placed on the base 2. A rack surface 73 is provided on the unlocking block 72. The gear 71 meshes with the rack surface 73.

[0023] Under the action of the first spring 81, the top block 8 is constantly pressed against the turntable 4;

[0024] Under the action of the second spring 43, the turntable 43 can rotate, and the column rod 42 always tends to press against the unlocking block 72.

[0025] This embodiment incorporates a rotary table 4 structure, allowing both locking and unlocking to be controlled by the rotation of the rotary table 4. This makes locking more stable, and the rotary table is less likely to generate rotational force during knocking and vibration, ensuring the security of the lock and preventing it from unlocking naturally during knocking and vibration. At the same time, the characteristic of the bolt being ejected after the rotary table is rotated and aligned makes the unlocking operation more convenient.

[0026] In actual operation, under the default state, that is, under the action of the first spring 81, the insertion port 41 on the turntable 4 is aligned with the top block 8. So when locking is required, simply grasp the lock cover 1 and insert the lock tongue 3 into the insertion port 41. During the insertion process, it will push the top block 8 and compress the first spring 81. When the lock head of the lock tongue 3 has completely passed through the insertion port 41, the turntable 4 will lose its limiting effect on the insertion port 41. Under the pushing action of the second spring 43, it will rotate. The column 42 on the turntable 4 will abut against the unlocking block 72. The insertion port 41 and the lock head 32 are misaligned. Even under the elastic force of the first spring 81, it will not be able to retract. Thus, you can remove your hand and lock the device. When unlocking is required, motor 7 operates, gear 71 rotates, driving unlocking block 72 to move to the other end and gradually pushing column 42, compressing second spring 43, and rotating turntable 4, so that insertion port 41 is aligned with lock head 32 again. Under the elastic force of first spring 81, lock head 32 is pushed outward, and bolt 3 is ejected. Motor 7 resets, while top block 8 remains in insertion port 41 under the hold of second spring 81. Turntable 4 cannot rotate, so insertion port 41 awaits the next insertion of bolt 3.

[0027] The stability of the locked structure is mainly achieved through two aspects. First, the second spring 43 pushes the turntable 4 to be offset, and the compression of the second spring 43 must be a return with a rotational angle, so it is not easy for external forces to exert this force. Second, the first spring 81 is added to exert a top pressure on the turntable 4, so that the turntable 4 requires more force to rotate without the motor 7 pushing it. This makes it more difficult to unlock naturally, thus achieving a stable structure after locking.

[0028] Furthermore, in order to restrict the movement of the turntable 4, the back of the turntable 4 in this embodiment is provided with a movable cavity 44, which is connected to the insertion port 41. The top of the top block 8 is placed in the movable cavity 44. This design can also reduce the overall thickness, so that part of the top block 8 is integrated into the turntable 4, thus reducing the thickness.

[0029] Furthermore, regarding the installation of the turntable 4, this embodiment directly selects to set a circular groove 21 inside the base 2, the turntable 4 is placed in the circular groove 21, and the case of the base 2 is provided with a lock hole 22 with a shape corresponding to the insertion port 41 at the circular groove 21.

[0030] Furthermore, regarding the installation of the top block 8, in this embodiment, the top block 8 is provided with limit blocks 82 at both ends, and the base 2 is provided with a sliding groove 23 opened in the vertical direction on the side of the circular groove 21. The limit blocks 82 are respectively placed in the corresponding sliding grooves 23, so that the top block 8 can only move in the vertical direction.

[0031] Furthermore, regarding the input of unlocking commands, this embodiment includes a biometric identification module 9 on the base 2, which is electrically connected to the circuit board 5. Specifically, the biometric identification module 9 is a fingerprint recognition module.

[0032] In addition, it should be noted that the lock head can be designed to rotate and connect with the lock bar. The top surface of the lock head can be chamfered. After the lock head pushes out the top block, the turntable drives the lock head to rotate, thus displacing the lock head from the keyhole. This also achieves the locking function.

[0033] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
