Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

Referring to fig. 1-5, the utility model discloses a U-shaped padlock, including: lock body housing 10, lock bar 20, locking bolt 30, control unit and drive mechanism.

The lock body shell 10 comprises a lock hole for the lock rod 20 to be inserted, and the bolt 30, the circuit board 40 and the driving mechanism are all arranged in the lock body shell 10.

Referring to fig. 3-4, the locking lever 20 is U-like and includes a longer pivoting end and a shorter inserting end, the pivoting end is pivoted with the lock body housing 10, and the bottom is provided with a locking lever spring 60; the plugging end is switched between a state of plugging the lock hole and a state of being separated from the lock hole, when the plugging end is plugged in the lock hole, the lock rod spring 60 is compressed, and the lock rod 20 has an upward movement trend; when the plugging end is separated from the locking hole, the locking bar spring 60 springs up the locking bar 20 by the spring force.

The first engaging groove 21 is disposed at the pivot end of the lock lever 20, the locking tongue 30 is transversely movably disposed in the first engaging groove 21, and the driving mechanism drives the locking tongue 30 to move in the horizontal direction, so that the locking tongue 30 is switched between a state of engaging with the first engaging groove 21 and a state of disengaging from the first engaging groove 21. When the inserting end of the lock rod 20 is inserted into the lock hole, the lock tongue 30 is clamped in the first clamping groove 21, so that the lock rod 20 cannot move, and the lock rod spring 60 is compressed; when the driving mechanism drives the locking bolt 30 to disengage from the first locking groove 21, the locking rod 20 is bounced by the resilience of the locking rod spring 60, and the unlocking is completed. While deadbolt spring 70 is compressed and there is a tendency for movement to cause deadbolt 30 to rebound.

The control unit is electrically connected with the driving mechanism to control the start and stop of the driving mechanism. Specifically, referring to fig. 5, the control unit is a circuit board 40, and the driving mechanism is an eccentric motor 50; the circuit board 40 is in wire communication with the eccentric motor 50, so that the circuit board 40 controls the start and stop of the eccentric motor 50. In addition, be provided with 2 contacts 41 that can switch on with power module on the circuit board 40 the utility model discloses well key is built-in button cell's electronic key, and accessible cell-phone app and bluetooth pair, make the key obtain correct address. The key is inserted into the lock, the key and the contact 41 are conducted, a loop is formed among the key, the circuit board 40 and the eccentric motor 50, and the eccentric motor 50 can be started and can complete unlocking through the series of transmission.

Specifically, referring to fig. 3 to 4, a second engaging groove 31 is formed at a lower portion of the locking tongue 30, and an output end of the eccentric motor 50 is disposed in the second engaging groove 31 and abuts against an inner sidewall of the second engaging groove 31. When the eccentric motor 50 is started, the output end rotates, and because the output end abuts against the inner side wall of the second slot 31, the rotation has a motion component in the horizontal direction, so that the bolt 30 moves and is separated from the first slot 21.

Specifically, the U-shaped padlock further includes a limit shaft 80. The limiting shaft 80 is horizontally arranged in the lock body housing 10, correspondingly, a limiting notch 22 is arranged on the pivot end of the lock rod 20, and one end of the limiting shaft 80 is horizontally arranged in the limiting notch 22. The limiting shaft 80 and the limiting notch 22 have the following functions: when the U-shaped padlock is in an unlocked state and needs to be locked, a user needs to align the insertion end with the lock hole and press the insertion end downwards, when the limiting notch 22 is tightly pressed against the limiting shaft 80, the positions of the first clamping groove 21 and the lock tongue 30 are just aligned, and the lock tongue 30 is rebounded by the lock tongue spring 70 and clamped in the first clamping groove 21, so that locking is completed. The limiting shaft 80 and the limiting notch 22 limit the downward inserting stroke of the inserting end, and the user only needs to press the inserting end to the end of the stroke with force to complete locking, and the locking can be realized without repeatedly aligning up and down.

Specifically, the U-shaped padlock also includes a circuit board housing 90 for mounting and protecting the circuit board 40. The circuit board housing 90 is fixedly disposed within the lock body housing 10. Particularly, the latch spring 70 is located at the side of the circuit board housing 90, and one end of the latch spring 70 is fixedly connected to the circuit board housing 90; when the eccentric motor 50 drives the latch 30 to be separated from the first catching groove 21, one end of the latch spring 70 is compressed and there is a movement tendency to bounce the latch 30.

Specifically, the U-shaped padlock further includes a motor support 100 for supporting and fixing the eccentric motor 50. The eccentric motor 50 is fixedly disposed in the motor support 100, and the motor support 100 is fixedly disposed in the lock body housing 10.

Specifically, the bottom of the lock body housing 10 is provided with a key hole 11 for a key to enter, and the key hole 11 is located at the lower part of the contact 41, so that the key can be directly conducted with the contact 41 when inserted.

Specifically, the U-shaped padlock also includes a waterproof plug 110. The waterproof plug 110 is movably disposed on the key hole 11, one end of the waterproof plug 110 is hinged to the bottom of the lock housing 10, and the other end is movably engaged with the bottom of the lock housing 10. When the waterproof plug 110 is in a closed state, the waterproof plug can cover the key hole 11, so that the key hole 11 is isolated from the external environment, and the internal electric elements are protected; when the lock needs to be unlocked, the movable end of the waterproof plug 110 is broken off, and then the key can be inserted.

The following explains the specific principle of unlocking: when the padlock is in a locked state, an operator opens the waterproof plug 110, inserts an adapted key into the key hole 11, and conducts the key with the circuit board 40, and the circuit board 40 drives the eccentric motor 50 to rotate, and pushes the second slot 31 in the horizontal direction, so that the lock tongue 30 is separated from the first slot 21, and the lock tongue spring 70 is compressed; the locking bar spring 60 rebounds to make the locking bar 20 bounce, and the plugging end is separated from the locking hole to complete unlocking. The eccentric motor 50 stops driving.

Accordingly, the specific principle of locking is as follows: when the padlock is in the unlocked state, locking bolt 30 is rebounded by locking bolt spring 70 and always bears against the surface of the pivoted end of locking rod 20. The user aims at the lock hole with the grafting end and presses with strength, and first draw-in groove 21 aligns with spring bolt 30, and spring bolt 30 receives the resilience of spring bolt spring 70 and blocks in first draw-in groove 21, makes locking lever 20 unable reciprocate, and the grafting end has also pegged graft in the lock hole simultaneously, accomplishes the closure.

Through the detailed explanation of the embodiment, it can be understood that the utility model improves the automation degree of unlocking, after the user inserts the corresponding key with the power supply into the control unit, the unlocking can be realized without the rotation of manpower, the use is more labor-saving, convenient and humanized, and the experience feeling of the user is improved; meanwhile, the condition that the key is broken off due to the fact that the key is rotated is avoided, and great inconvenience brought to a user is reduced.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
