Smart electronic padlock

Abstract

This invention relates to a smart electronic padlock, comprising a lock housing, a mounting base integrated within the lock housing, a drive structure, and a locking mechanism. The drive structure, mounted on the mounting base, includes a power supply unit, a motor, and a drive assembly. The drive assembly includes a ratchet shaft and a ratchet disc. The ratchet shaft is connected to the motor and rotates downwards to engage the ratchet disc, thereby driving the ratchet disc to rotate. The locking mechanism includes a lock hook, a lever, a locking plate, and a locking assembly. The lock hook is movably mounted on the lock housing and includes an actuating section and a locking section. The actuating section incorporates a lever, and the locking section has a locking groove. The locking plate engages with the ratchet disc and has a groove, and rotates under the drive of the ratchet disc. The locking assembly includes a hook base and a resilient locking assembly. The hook base abuts against the locking plate and has a hook. The resilient locking assembly is located on the hook base and has a locking portion, which selectively engages with the locking groove; this prevents the motor gears from breaking when not driven, thereby maintaining service life and reliability.

Claims

1. A smart electronic padlock, comprising: a lock housing; and a mounting base, which is fitted within the lock housing; A drive structure, mounted on the mounting base, includes an inductive power supply group, a motor electrically connected to the inductive power supply group, and a drive group driven by the motor. The drive group includes a ratchet shaft and a ratchet disc. The ratchet shaft is connected to the motor and engages with the ratchet disc in a first downward direction, thereby driving the ratchet disc to rotate. A locking structure includes a locking hook, a lever, a locking plate, and a locking assembly. The locking hook is movably coupled to the lock housing and includes an actuating section and a latching section extending from the actuating section. The actuating section is coupled with the lever, and the latching section has a latching groove. The locking plate fits onto the ratchet disc and has a groove, and is rotated by the ratchet disc. The locking assembly includes a hook base and a resilient latch assembly. The hook base abuts against the locking plate and has a hook. The resilient latch assembly is disposed on the hook base and has a locking portion that can engage the latching groove. The inductive power supply is driven by an external component to rotate the motor. The ratchet shaft is driven by the motor to rotate in the first direction and engage the ratchet disc. The ratchet disc drives the locking plate to rotate in the first direction. The hook seat rotates with the locking plate, so that the hook falls into the groove, thereby causing the locking part to disengage from the slot.

2. The smart electronic padlock as described in claim 1, wherein the inductive power supply group includes a control board and an inductive communication element and a power supply element electrically connected to the control board, wherein the inductive communication element receives an external signal and transmits it to the control board so that the power supply element supplies power to the motor.

3. The smart electronic padlock as described in claim 1, wherein the mounting base is provided with a guide block corresponding to the position of the lever, the actuating section is provided with a necking portion, the lever is provided with a slot, the lever engages with the necking portion through the slot and is attached to the actuating section, and moves along the guide block.

4. The smart electronic padlock as described in claim 1, wherein the locking plate is provided with a shaft hole and a pair of limiting holes communicating with the shaft hole, the ratchet disc has a push pin and a pair of protrusions, the ratchet disc passes through the shaft hole, thereby enabling the pair of protrusions to move in the pair of limiting holes, and the ratchet disc rotates through the push pin being pushed by the push pin.

5. The smart electronic padlock as described in claim 1, wherein the lock housing includes a cylindrical section and a base and a top cover attached to the opposite side of the cylindrical section, the actuating section and the latching section of the lock hook are inserted into the outer edge of the cylindrical section, the periphery of the locking plate is provided with the groove and a limiting groove, the base is provided with a limiting block, and the limiting block moves in the limiting groove.

6. The smart electronic padlock as claimed in claim 1, wherein the ratchet shaft has a rotating shaft, the motor has a motor shaft, and the motor drives the ratchet shaft to rotate via the motor shaft connected to the rotating shaft.

7. The smart electronic padlock as claimed in claim 1, wherein the ratchet shaft has a plurality of first ratchet teeth, the ratchet disc has a plurality of second ratchet teeth, and the ratchet disc rotates in the first direction along with the ratchet shaft by engaging the first ratchet teeth with the second ratchet teeth.

8. The smart electronic padlock as described in claim 1, wherein the latching assembly further includes an elastic element, one end of which is connected to the hook base and the other end of which elastically abuts against the inner wall of the lock housing.

9. The smart electronic padlock as claimed in claim 1, wherein the resilient latch assembly includes a spring and a latching member abutting the spring, the spring being disposed in the hook seat, and the latching portion being located at one end of the latching member protruding from the hook seat.

10. The smart electronic padlock as described in claim 5, wherein the drive structure further includes an elastic pressure member and a locking member, the elastic pressure member being disposed between the base and the ratchet disc, and the locking member passing through the ratchet disc and engaging with the ratchet shaft.
