Preferably, the lower clamping plate is extended outward to form a bottom support plate for accommodating the zipper slider.
Compared with the prior art, the electronic lock of the present invention combines a lower clamping plate, a locking assembly, and a connecting assembly. The bottom of the locking assembly corresponds to the lower clamping plate to form an upper clamping plate, which is located above the lower clamping plate. The upper clamping plate has a clamping position for clamping a zipper relative to the lower clamping plate and an unclamping position for releasing the zipper. The upper clamping plate and the lower clamping plate are connected through the connecting assembly so that the upper clamping plate is locked at the clamping position relative to the lower clamping plate. By clamping between the upper and lower clamping plates, the electronic lock with a fixed zipper slider 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 with a fixed zipper slider at the end of the zipper, with the upper clamping plate and the lower clamping plate positioned on the top and bottom sides of the zipper end, respectively. The upper clamping plate and the lower clamping plate are connected through the connecting assembly, so that the upper clamping plate is locked at the clamping position relative to the lower clamping plate. By clamping the sides of the zipper between the upper and lower clamping plates, the electronic lock with a fixed zipper slider is now fixed on the zipper, thus achieving a detachable connection between the electronic lock with a fixed zipper slider and the zipper. The locking assembly has a rotatable encircling member, and a locking area for locking the zipper slider is formed between the lower clamping plate and the encircling member. The zipper slider is locked in the locking area or the locking area is opened by rotating the encircling member. In other words, the locking or unlocking of the zipper slider is achieved by opening or closing the locking area.
To provide a detailed explanation of the technical content, and structural features of the present invention, the following is further explained in conjunction with the implementation method and the accompanying drawings.

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.
