Description

Technical Field

[0001] This utility model relates to the field of padlock technology, and in particular to an anti-knock smart padlock. Background Technology

[0002] A padlock is a common type of lock, typically consisting of a lock body, a lock cylinder, and a shank. The lock body of a padlock is equipped with a shank, which is a ring-shaped or straight metal bar that can be fastened to the lock body to form a closed lock.

[0003] Padlocks can be categorized into ordinary padlocks, anti-theft padlocks, waterproof padlocks, and fireproof padlocks. Ordinary padlocks are suitable for general door locks, luggage locks, etc.; anti-theft padlocks have high anti-theft performance and are usually used for door locks in important locations; waterproof padlocks have a waterproof design and can be used in humid environments; fireproof padlocks have fire-resistant properties and can protect the internal components of the lock from damage in the event of a fire.

[0004] Currently, existing padlock products on the market have significant technical flaws in addressing the issue of the latch unlocking due to inertia. Most low-cost padlocks, in order to reduce production costs, only use thin springs with low elasticity to maintain the latch's lock on the hook. This simple design makes it easy for the latch to overcome the spring resistance and move backward when faced with a slightly larger inertial force, resulting in the lock being easily unlocked. Secondly, striking the side of the lock case with a heavy object such as a hammer can cause the latch, which is installed inside the lock case, to slide laterally within the lock case under external force. Once the latch disengages from the clasp, the clasp is no longer locked and can be easily pulled out, unlocking the lock and causing incalculable losses to the user.

[0005] Therefore, it is necessary to research a new technical solution to address the above problems. Utility Model Content

[0006] In view of the above, this utility model addresses the deficiencies of the existing technology, and its main purpose is to provide an anti-knock smart padlock. Through the structural design and cooperation between the tongue, rotating block, reset component, and drive assembly, the tongue is provided with at least a first limiting part and a second limiting part. The rotating block has a pressing part. The drive assembly rotates in conjunction with the rotating block to switch the tongue between a locked state and an unlocked state. Thus, in the locked state, the reset component can press the pressing part against the first limiting part, locking the locking end of the hook within the locked position, preventing the tongue from retracting due to inertia and overcoming the spring force when the lock body is struck, thus preventing the lock hook from popping out and unlocking.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A knock-resistant smart padlock includes:

[0009] The lock body has at least one movable groove and a locking position;

[0010] The hook is movably mounted on the lock body;

[0011] A tongue piece is movably disposed within a movable groove; the tongue piece is provided with at least a first limiting part and a second limiting part.

[0012] A rotating block is movably disposed in a movable groove, and the rotating block has a pressing part;

[0013] Reset component;

[0014] A drive assembly drives a rotating block to rotate, switching the tongue between a locked state and an unlocked state. In the locked state, a reset member enables the abutment to press against the first limit portion, and the locking end of the hook is locked in the locking position.

[0015] In the unlocked state, the rotating block moves relative to the movable groove, causing the abutting part to abut against the second limiting part, and the locking end of the hook to move away from the locking position.

[0016] As a preferred embodiment, in the unlocked state, the drive component drives the rotating block to move the tongue backward, so that the front end of the tongue abuts against the rear side of the hook.

[0017] As a preferred embodiment, the movable groove is further provided with a first locking part, and the outside of the tongue is provided with a second locking part that cooperates with the first locking part. In the locked state, the first locking part and the second locking part are locked to each other. In the unlocked state, the first locking part and the second locking part are unlocked by moving away from each other. With the cooperation of the double locking structure, the lock is prevented from being knocked open by external force when locked.

[0018] As a preferred embodiment, a first mounting part is provided inside the movable groove, and a second mounting part is provided outside the tongue. A first elastic element is also provided between the first mounting part and the second mounting part. In the locked state, the first elastic element is in a released state, and in the unlocked state, the first elastic element is in a stored state.

[0019] As a preferred embodiment, the end of the hook facing the movable groove is also provided with an abutment groove, and the end of the tongue near the abutment groove is also provided with an abutment part for cooperating with the abutment groove. In the locked state, the abutment part abuts against the abutment groove, and in the unlocked state, the abutment part moves away from the abutment groove to prevent the lock from being knocked open by external force when locked, thereby improving the locking stability of the padlock.

[0020] As a preferred embodiment, the tongue includes a first transverse portion, a second transverse portion, a first vertical portion, and a second vertical portion. The first transverse portion, the second transverse portion, the first vertical portion, and the second vertical portion form a receiving position that is vertically and through. The rotating block is movably disposed within the rotating position. The first limiting portion is recessed on the first transverse portion, and the second limiting portion is disposed on the first vertical portion.

[0021] As a preferred embodiment, the drive assembly includes a motor and a rotating shaft. The output end of the motor is connected to the rotating shaft, and the rotating shaft is connected to a rotating block. The motor controls the rotation of the rotating shaft to cause the rotating block to rotate around the receiving position.

[0022] As a preferred embodiment, the lock body is further provided with a mounting groove and a through groove. The mounting groove is connected to the movable groove. The through groove is connected to the mounting groove. A baffle is provided in the through groove. One end of the baffle extends into the mounting groove. A limiting groove is provided at the lower end of the hook. The hook is closable in the mounting groove. When locked, the baffle abuts against the limiting groove to restrict the opening and closing movement of the hook in the lock body.

[0023] As a preferred embodiment, the anti-knock smart padlock also includes a housing, which is fitted over the lock body, and the housing is provided with a bevel at the corresponding baffle.

[0024] As a preferred embodiment, the hook has a connecting end, the lower end of which is provided with an annular groove, a sleeve portion is provided in the mounting groove, and a second elastic member is provided between the connecting end and the sleeve portion. One end of the second elastic member is sleeved in the annular groove, and the other end of the second elastic member is sleeved outside the sleeve portion.

[0025] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly relies on the structural design and cooperation between the tongue, the rotating block, the reset component and the drive assembly. The tongue is provided with at least a first limiting part and a second limiting part. The rotating block has a pressing part. The drive assembly rotates the rotating block to switch the tongue between the locked state and the unlocked state. In the locked state, the reset component can make the pressing part press against the first limiting part, so that the locking end of the hook is locked in the locking position, preventing the tongue from overcoming the spring force and retracting under the action of inertia when the lock body is struck, thus causing the lock hook to pop out and unlock.

[0026] Secondly, the cooperation between the first locking part and the second locking part ensures that in the locked state, the first locking part and the second locking part are locked to each other, so that they can only move when the drive component rotates, preventing the lock from being knocked open by external force when locked.

Preferably, the end of the hook 20 facing the movable groove 11 is also provided with an abutment groove 24.

[0071] The tongue 30 is provided with a second locking part 31 that cooperates with the first locking part 111. In the locked state, the first locking part 111 and the second locking part 31 are locked to each other. In the unlocked state, the first locking part 111 and the second locking part 31 are unlocked by moving away from each other. With the cooperation of the double locking structure, the lock is prevented from being knocked open by external force when locked.

[0072] The tongue 30 is also provided with an abutment part 32 at one end near the abutment groove 24 for cooperating with the abutment groove 24. In the locked state, the abutment part 32 abuts against the abutment groove 24. In the unlocked state, the abutment part 32 is away from the abutment groove 24 to prevent the lock from being knocked open by external force when locked, thereby improving the locking stability of the padlock.

[0073] The tongue 30 is movably disposed within the movable groove 11; the tongue 30 is provided with at least a first limiting part 301 and a second limiting part 302; preferably, the tongue 30 includes a first horizontal part 33, a second horizontal part 34, a first vertical part 35 and a second vertical part 36, the first horizontal part 33, the second horizontal part 34, the first vertical part 35 and the second vertical part 36 form a vertically through receiving position 37, the rotating block 40 is movably disposed within the rotating position, the first limiting part 301 is recessed on the first horizontal part 33; the second limiting part 302 is disposed on the first vertical part 35.

[0074] Preferably, a first mounting part 112 is provided in the movable groove 11, and a second mounting part 38 is provided on the outside of the tongue 30. A first elastic member 39 is also provided between the first mounting part 112 and the second mounting part 38. In the locked state, the first elastic member 39 is in the energy-releasing state, and in the unlocked state, the first elastic member 39 is in the energy-storing state.

[0075] The rotating block 40 is movably disposed in the movable groove 11, and the rotating block 40 has a pressing part 41;

[0076] The drive assembly 50 drives the rotating block 40 to rotate, so as to switch the tongue 30 between a locked state and an unlocked state. In the locked state, the reset member 60 can make the abutting part 41 abut against the first limiting part 301, and the locking end of the hook 20 is locked in the locking position 12; wherein, the reset member 60 is a reset torsion spring.

[0077] In the unlocked state, the rotating block 40 moves relative to the movable groove 11, causing the abutting part 41 to abut against the second limiting part 302, and the locking end of the hook 20 is moved away from the locking position 12.

[0078] Preferably, in the unlocked state, the drive assembly 50 drives the rotating block 40 to move the tongue 30 backward, so that the front end of the tongue 30 abuts against the rear side of the hook 20.

[0079] Preferably, the drive assembly 50 includes a motor 51 and a rotating shaft 52. The output end of the motor 51 is connected to the rotating shaft 52, and the rotating shaft 52 is connected to the rotating block 40. The motor 51 controls the rotation of the rotating shaft 52 to cause the rotating block 40 to rotate around the receiving position 37. The motor 51 rotates only once in one direction after receiving an unlocking command. When locking, the motor 51 does not need to rotate again, so the PCB board 101 does not need to have a microswitch to lock the hook 20 into position. Furthermore, the motor 51 does not need to frequently reverse direction, greatly increasing the service life of the padlock.

[0080] The general working principle of this embodiment is described in detail below:

[0081] When locking, the drive assembly 50 drives the abutment 41 to press against the first limiting part 301, so that the locking end of the hook 20 is locked in the locking position 12. At this time, the rotating block 40 will block the tongue 30 under the action of the reset member 60 (e.g. Figure 9 (as shown);

[0082] When unlocking, the motor 51 rotates the rotating shaft 52, which in turn drives the rotating block 40. At this time, the tongue 30 retracts to its maximum position under the drive of the rotating block 40. The latch then automatically pops open, completing the unlocking process. After the latch pops open, the motor 51 continues to rotate until the rotating block 40 touches the second limiting part 302 of the tongue 30 and stops. At this time, the reset piece 60 under the rotating block 40 is in an energy storage state (e.g., ...). Figure 10 (As shown).

[0083] When the hook 20 is pressed down again to lock, the abutment groove 24 of the hook 20 passes through the abutment portion 32 of the tongue 30. Under the action of the first elastic member 39, the abutment portion 32 of the tongue 30 engages with the abutment groove 24, locking the hook 20. At this time, the second limiting portion 302 of the tongue 30 moves away from the pressing portion 41 of the rotating block 40. The pressing portion 41 then rotates to the first limiting portion 301 of the tongue 30 under the action of the return torsion spring 60, preventing the tongue 30 from inertially retracting.

[0084] The key design feature of this utility model lies in the structural design and cooperation between the tongue, rotating block, reset component, and drive assembly. The tongue is provided with at least a first limiting part and a second limiting part. The rotating block has a pressing part. The drive assembly rotates the rotating block in conjunction with the tongue to switch the tongue between a locked state and an unlocked state. In the locked state, the reset component presses the pressing part against the first limiting part, so that the locking end of the hook is locked in the locked position, preventing the tongue from retracting due to inertia and overcoming the force of the spring when the lock body is struck, thus preventing the lock hook from popping out and unlocking.

[0085] Secondly, the cooperation between the first locking part and the second locking part ensures that in the locked state, the first locking part and the second locking part are locked to each other, so that they can only move when the drive component rotates, preventing the lock from being knocked open by external force when locked.

[0086] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
