Description

Technical Field

[0001] The utility model relates to a lock, in particular to an intelligent U-shaped lock. Background Art

[0002] A U-shaped lock is a type of lock primarily used on glass doors, motorcycles, and electric scooters. Conventional U-shaped locks are classified by their locking control method into two types: mechanical and electronic. Mechanical locking involves using a key to lock or unlock the lock, while electronic locking involves an electronic control system to lock or unlock the lock.

[0003] Existing smart U-shaped locks are generally provided with a reset switch to reset the password and fingerprint. The reset switch of the existing U-shaped lock is generally arranged inside the lock body. When resetting is required, the lock body shell needs to be opened to achieve the reset. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the present invention aims to provide a smart U-shaped lock. The present invention uses a key to control the reset switch, which can be reset without removing the lock body, making it easy to change fingerprints and passwords.

[0005] The purpose of the utility model is achieved through the following technical solutions: an intelligent U-shaped lock, comprising a U-shaped locking rod and a lock body, the lock body being provided with two through-holes, the inner side walls of the two through-holes being provided with lock tongue extension holes, the two ends of the U-shaped locking rod being respectively passed through the through-holes, an inner lock body being provided within the lock body, a PCB board being provided at the bottom of the inner lock body, a locking rod mounting slot and a lock core mounting slot being provided at the upper end of the inner lock body, two locking rods being provided in the locking rod mounting slot, springs being sleeved on the outside of the two locking rods, a lock core being provided in the lock core mounting slot, a rotary toggle block being provided at one end of the lock core, a reset switch being provided on the PCB board, the reset switch being located below the rotary toggle block, and the rotary toggle block being driven to rotate by turning the lock core with a key, and the two locking rods being driven to move at the same time.

[0006] As an improvement to the smart U-shaped lock of the present invention, two toggle rods are provided on the rotating toggle block at intervals, and both of the lock rods are provided with a first toggle abutting block. When the rotating toggle block rotates, the two toggle rods can respectively abut against the first toggle abutting block. The two first toggle abutting blocks are arranged correspondingly up and down, and there is a distance between the two first toggle abutting blocks.

[0007] As an improvement to the smart U-shaped lock of this utility model, when the rotary toggle block rotates, the toggle lever can press the reset switch. If the toggle lever presses the reset switch for a single time equal to 5 seconds to 10 seconds, the reset switch is reset. If the toggle lever presses the reset switch for a single time less than 5 seconds, the reset switch is not reset. The reset switch can be reset by turning the lock cylinder with a key, causing the toggle lever to press the reset switch for 5 seconds to 10 seconds.

[0008] As an improvement to the smart U-shaped lock of the present invention, when the toggle lever continuously presses the reset switch 3 to 5 times, the reset switch is reset. When the toggle lever continuously presses the reset switch less than 3 times, the reset switch is not reset. The reset control of the reset switch can also be controlled by the number of times the toggle lever continuously presses the reset switch. When unlocking with a key, the rotation of the toggle lever will contact the reset switch. If it is set to require multiple presses or long presses to achieve a reset, it will not affect the normal unlocking of the key.

[0009] As an improvement to the smart U-shaped lock of the present invention, a motor mounting slot is further provided at the upper end of the inner lock body, a motor is provided in the motor mounting slot, the motor is electrically connected to the PCB board, a rotating block is provided on the output shaft of the motor, two push rods are provided on the rotating block at intervals, and the motor can drive the rotating block to rotate when started.

[0026] like Figure 1-Figure 5As shown, an intelligent U-shaped lock comprises a U-shaped locking rod 1 and a lock body 2. The lock body 2 is provided with two through-holes 3. The inner side walls of the two through-holes 3 are provided with a lock tongue extension hole 4. The two ends of the U-shaped locking rod 1 are respectively penetrated into the through-holes 3. An inner lock body 5 is provided in the lock body 2. A PCB board 6 is provided at the bottom of the inner lock body 5. A locking rod mounting groove 7 and a lock core mounting groove 8 are provided at the upper end of the inner lock body 5. Two locking rods 9 are provided in the locking rod mounting groove 7. A spring 10 is sleeved on the outside of the two locking rods 9. A lock core 11 is provided in the lock core mounting groove 8. A rotary toggle block 12 is provided at one end of the lock core 11. A reset switch 13 is provided on the PCB board 6. The reset switch 13 is located below the rotary toggle block 12. Rotating the lock core 11 by a key can drive the rotary toggle block 12 to rotate and simultaneously drive the two locking rods 9 to move. The movement directions of the two locking rods 9 are opposite. A battery installation slot 103 is further provided at the upper end of the inner lock body 5 . A lithium battery 104 is provided in the battery installation slot 103 . The lithium battery 104 is electrically connected to the PCB board 6 .

[0027] Preferably, two toggle rods 121 are provided on the rotating toggle block 12 at intervals, and the two locking rods 9 are provided with a first toggle abutting block 91.

The two first toggle abutting blocks 91 are correspondingly arranged up and down, and there is a distance between the two first toggle abutting blocks 91.

[0028] The first type of reset control for the reset switch 13 is that when the rotary toggle block 12 rotates, it drives the toggle rod 121 to press the reset switch 13 downward. If the toggle rod 121 presses the reset switch 13 for a single time of 5 seconds, the reset switch 13 is reset. If the toggle rod 121 presses the reset switch for a single time of less than 5 seconds, the reset switch 13 is not reset. The reset control of the reset switch 13 can be achieved by rotating the lock cylinder 11 with a key, causing the toggle rod 121 to press the reset switch for 5 seconds.

[0029] The second reset control of the reset switch 13 is that when the rotary toggle block 12 rotates, the toggle rod 121 can press the reset switch 13. When the toggle rod 121 presses the reset switch 13 for 10 seconds, the reset switch 13 is reset. When the toggle rod 121 presses the reset switch 13 for less than 5 seconds, the reset switch 13 is not reset.

[0030] The third reset control of the reset switch 13 is that if the toggle lever 121 continuously presses the reset switch 13 three times, the reset switch 13 is reset. If the toggle lever 121 continuously presses the reset switch 13 less than three times, the reset switch 13 is not reset. When unlocking with a key, since the toggle lever 121 rotates and contacts the reset switch 13, if it is set to require multiple or long presses to reset, it will not affect normal key unlocking.

[0031] The fourth reset control of the reset switch 13 is that when the toggle lever 121 continuously presses the reset switch 13 5 times, the reset switch 13 is reset; when the toggle lever 121 continuously presses the reset switch 13 less than 3 times, the reset switch 13 is not reset.

[0035] When locked, one end of the lock tongue 94 extends from the lock tongue extension hole 4 and cooperates with the limiting groove 101 on the U-shaped lock rod 1 to limit the movement of the U-shaped lock rod 1 in the through hole 3. The ends of the two lock rods 9 are also respectively provided with a spring support block 96, and one end of the spring 10 supports the spring support block 96.

[0036] Preferably, one end of the lock body 2 is provided with a waterproof plug mounting slot 22, which is provided with a lock core mounting hole 23, a waterproof cover connection hole 24, and a USB charging port 25. A waterproof cover 26 covers the waterproof plug mounting slot 22, which is provided with a connecting rod 21, which is inserted into the waterproof cover connection hole 24. A USB is provided in the USB charging port 25, which is electrically connected to the PCB board 6.
