Referring to FIGS. 1 to 6, the electronic lock with a fixed zipper slider 100 according to the present invention includes a lower clamping plate 1, a locking assembly 2, and a connecting assembly 3. The bottom of the locking assembly 2 corresponding to the lower clamping plate 1 is formed with an upper clamping plate 21. The upper clamping plate 21 is located above the lower clamping plate 1 and has a clamping position (as shown in FIGS. 1-2) for clamping a zipper relative to the lower clamping plate 1, and an unclamping position for releasing the zipper. The upper clamping plate 21 and the lower clamping plate 1 are connected through the connecting assembly 3 so that the upper clamping plate 21 is locked at the clamping position relative to the lower clamping plate 1. By clamping between the upper and lower clamping plates 21 and 1, the electronic lock 100 of the present invention can be fixed on any device with a zipper. When in use, the user simply needs to open the zipper to be installed, place the electronic lock 100 at the end of the zipper, with the upper clamping plate 21 and the lower clamping plate 1 positioned on the top and bottom sides of the zipper end, respectively. The upper clamping plate 21 and the lower clamping plate 1 are connected through the connecting assembly 3, so that the upper clamping plate 21 is locked at the clamping position relative to the lower clamping plate 1. By clamping the sides of the zipper between the upper and lower clamping plates 21 and 1, the electronic lock 100 is now fixed on the zipper, thus achieving a detachable connection between the electronic lock 100 and the zipper. The locking assembly 2 has a rotatable encircling member 22. A locking area for locking the zipper slider 20 is formed between the lower clamping plate 1 and the encircling member 22. The zipper slider 20 can be locked in the locking area or the locking area can be opened by rotating the encircling member 22. In other words, the locking or unlocking of the zipper slider 20 is achieved by opening or closing the locking area.

More specifically, referring to FIGS. 3 to 4, the lower clamping plate 1 includes a main plate 11 and a pressing toothed rack 12, which is arranged on the pressing surface of the main plate 11. The pressing toothed rack 12 is skidproof. Preferably, the pressing toothed racks 12 are symmetrically arranged on both sides of the main plate 11. For example, the connecting assembly 3 includes a threaded hole 31 and a hand screw 32. The threaded hole 31 is arranged on the upper clamping plate 21, and the lower clamping plate 1 has a locking hole (not shown). The hand screw 32 passes through the locking hole and connects with the threaded hole 31, so that the upper clamping plate 21 is locked at the clamping position relative to the lower clamping plate 1.

Referring to FIGS. 3 to 6, the locking assembly 2 further includes a casing 23, an electronic subassembly 24, a drive mechanism 25, and a lock tongue 26. The bottom of the casing 23 is formed with the upper clamping plate 21. The electronic subassembly 24 is built into the casing 23, and the drive mechanism 25 is electrically connected to the electronic subassembly 24. The output end of the drive mechanism 25 is matched with the lock tongue 26. The lock tongue 26 is slidably arranged in the casing 23 and has a locking position that engages with the encircling member 22 and an unlocking position that disengages from the encircling member 22 relative to the casing 23. The lock tongue 26 is switched between the locking position and the unlocking position under the drive of drive mechanism 25.

Referring to FIGS. 1 to 6, the encircling member 22 has a mating hole 223. When the lock tongue 26 is in the locking position, the lock tongue 26 extends and engages with the mating hole 223. When the lock tongue 26 is in the unlocking position, the lock tongue 26 retracts and disengages from the mating hole 223, thereby allowing the encircling member 22 to rotate freely.

Referring to FIGS. 3 to 4, the drive mechanism 25 is a drive motor, and the output end of the drive motor has an extendable and retractable pushing part 251. The lock tongue 26 always tends to move from the unlocking position to the locking position, and the lock tongue 26 has a matching drive part 261 corresponding to the pushing part 251. Thus, the matching drive part 261 can be pushed by the pushing part, thereby driving the lock tongue 26 to move from the unlocking position to the locking position.

Referring to FIGS. 1 to 6, the locking assembly 2 further includes an elastic member 2a, which provides an elastic force that always tends to move the lock tongue 26 from the unlocking position to the locking position. In other embodiments, the drive mechanism 25 includes an electrostrictive wire which is a special material that will be contracted when energized. As a result, the contraction of the electrostrictive wire drives the mechanical movement of the lock tongue 26, thereby achieving the purpose of unlocking and locking.

Refer to FIG. 1, the casing 23 has a rotating protrusion 231, and the encircling member 22 has a rotating hole 221 corresponding to the rotating protrusion 231. The rotating protrusion 231 is rotatably arranged in the rotating hole 221. The cooperation between the rotating protrusion 231 and the rotating hole 221 allows the encircling member 22 to move more smoothly. Specifically, the encircling member 22 has a cover 222, which can cover the zipper slider 20. The lower clamping plate 1 is extended outward to form a bottom support plate 14 for accommodating the zipper slider 20, thereby facilitating the zipper slider 20 to enter or exit.

Refer to FIG. 6, the encircling member 22 includes a first rod 224, a second rod 225, and a third rod 226 connected in sequence. The first rod 224 is perpendicular to the second rod 225, and the second rod 225 is perpendicular to the third rod 226. Both the free end of the first rod 224 and the free end of the third rod 226 are provided with the rotating holes 221. The middle of the first rod 224 is connected to the lock tongue 26.

Referring to FIGS. 3 to 6, the electronic subassembly 24 includes a touch panel, a charging port, a battery, and an indicator light. The battery is built into the casing 23. The touch panel is electrically connected to the battery. The charging port is located on the casing 23 and is electrically connected to the battery. The indicator light is located on the touch panel. The drive mechanism 25 is electrically connected to both the touch panel and the battery.

Referring to FIGS. 1 to 6, the working process of the electronic lock 100 of the present invention follows.

When in use, the user simply needs to open the zipper to be installed, and place the electronic lock 100 at the end of the zipper, with the upper clamping plate 21 and the lower clamping plate 1 positioned on the top and bottom sides of the zipper end, respectively. The upper clamping plate 21 and the lower clamping plate 1 are connected through the connecting assembly 3, thus the upper clamping plate 21 is locked at the clamping position relative to the lower clamping plate 1. By clamping the sides of the zipper between the upper and lower clamping plates, the electronic lock 100 is fixed on the zipper.

By manually operating the touch panel or button to activate the drive mechanism 25, the pushing part 251 is extended under the drive of the drive mechanism 25; as a result, the extension of the pushing part 251 pushes the matching drive part 261 and drives the lock tongue 26 to move from the locking position to the unlocking position, and the encircling member 22 is rotated to close the locking area, thereby achieving the locking of the zipper slider.

By manually operating the touch panel or button to activate the drive mechanism 25, the pushing part 251 is retracted under the drive of the drive mechanism 25; as a result, the retraction of the pushing part 251 allows the lock tongue 26 to move from the unlocked position to the locked position under the action of the elastic member. Accordingly, the lock tongue 26 extends into the mating hole 223 to restrict the rotation of the encircling member 22, thereby achieving the locking function.

To unlock, by manually operating the touch panel using a personal fingerprint or a password to activate the drive mechanism 25, the drive mechanism 25 causes the pushing part 251 to extend. The extension of the pushing part 251 pushes against the matching drive part 261 and moves the lock tongue 26 from the locked position to the unlocked position. When the lock tongue 26 is in the unlocked position, it retracts and disengages from the mating hole 223, allowing the encircling member 22 to rotate freely so as to open the locking area, thereby achieving the unlocking of the zipper slider 20.

By combining the lower clamping plate 1, the locking assembly 2, and the connecting assembly 3, the bottom of the locking assembly 2 corresponding to the lower clamping plate 1 is formed with the upper clamping plate 21. The upper clamping plate 21 is located above the lower clamping plate 1, and has a clamping position for clamping the zipper relative to the lower clamping plate 1 and an unclamping position for releasing the zipper. The upper clamping plate 21 and the lower clamping plate 1 are connected through the connecting assembly 3 so that the upper clamping plate 21 is locked at the clamping position relative to the lower clamping plate 1. By clamping between the upper and lower clamping plates, the electronic lock 100 of the present invention can be fixed on any device with a zipper. When in use, the user simply needs to open the zipper to be installed, and place the electronic lock 100 at the end of the zipper, with the upper clamping plate 21 and the lower clamping plate 1 positioned on the top and bottom sides of the zipper end, respectively. The upper clamping plate 21 and the lower clamping plate 1 are connected through the connecting assembly 3, so that the upper clamping plate 21 is locked at the clamping position relative to the lower clamping plate 1. By clamping the sides of the zipper between the upper and lower clamping plates, the electronic lock 100 is now fixed on the zipper, thus achieving a detachable connection between the electronic lock 100 and the zipper. The locking assembly 2 has a rotatable encircling member 22. A locking area for locking the zipper slider 20 is formed between the lower clamping plate 1 and the encircling member 22. The zipper slider can be locked in the locking area or the locking area can be opened by rotating the encircling member 22. In other words, the locking or unlocking of the zipper slider is achieved by opening or closing the locking area.
