when the first driving wheel 51 is driven by the driving motor 50 to rotate, the front end of the first driving wheel 51 is in a flat column structure to press the side wall surfaces of the first unlocking notch 301 and the second unlocking notch 401, so that the first slider 30 and the second slider 40 respectively overcome the elastic force of the elastic component and move inwards along the distribution direction thereof to exit the locking notch b.

Based on the above structural arrangement, when locking is required (refer to fig. 4, 5 and 9), the U-shaped lock ring 20 can be inserted into the mortise lock shaft cavity a in an aligned manner, and the first slider 30 and the second slider 40 automatically move outwards (i.e. move towards both sides) along the distribution direction of the first slider 30 and the second slider 40 under the driving of the elastic component to extend into the locking notch b to be aligned and clamped with the locking grooves c on the shaft wall parts 21 at both ends of the U-shaped lock ring 20, so as to realize a locking function; when unlocking is required (refer to fig. 7), the fingerprint recognizer 60 can be used to perform fingerprint recognition to determine whether the unlocking signal is correct, and after the driving controller obtains the correct unlocking signal, the first driving wheel 51 can be controlled to rotate by the driving motor 50, so that two wide side wall surfaces of the flat cylindrical front end of the first driving wheel 51 can extrude the side wall surfaces of the first unlocking notch 301 and the second unlocking notch 401 positioned at two sides of the flat cylindrical front end in the rotating process (the width of the flat cylindrical front end is widened in the rotating process), the overlapped area of the first unlocking notch 301 and the second unlocking notch 401 is enlarged, the first sliding block 30 and the second sliding block 40 are forced to overcome the elastic force of the elastic component and contract inwards along the distribution direction of the elastic component respectively, the outer ends of the first sliding block 30 and the second sliding block 40 can exit from the locking opening b, and the U-shaped locking ring 20 can be pulled out of the mortise lock shaft cavity a to realize the unlocking function; meanwhile, when the first driving wheel 51 continues to rotate, the two wide side wall surfaces at the flat cylindrical front end of the first driving wheel 51 can continue to rotate until the two wide side wall surfaces at the flat cylindrical front end face the inner and outer side wall surfaces of the first unlocking notch 301 and the second unlocking notch 401 (the width of the flat cylindrical front end is narrowed in the process), so that enough space is reserved in the first unlocking notch 301 and the second unlocking notch 401 for overlapping, and the first slider 30 and the second slider 40 can automatically move outwards along the distribution direction of the first slider 30 and the second slider 40 to extend into the locking notch b under the driving of the elastic assembly, so that locking is automatically performed.

In order to facilitate the use of the lock device, the lock device has an automatic unlocking function (see fig. 3, 4, 9 and 10), an unlocking spring 101 is provided in the mortise lock shaft cavity a of the present embodiment, the rear end of the unlocking spring 101 is fixed to the rear end of the mortise lock shaft cavity a, and the front end of the unlocking spring 101 is adapted to abut against the rear end surfaces of the shaft wall portions 21 at both ends of the U-shaped lock ring 20. Therefore, in an unlocking state, namely when the outer ends (the outer ends on both sides) of the first slider 30 and the second slider 40 exit from the locking notch b, the locking state of the outer ends of the first slider 30 and the second slider 40 and the locking groove c on the U-shaped locking ring 20 can be released, and the shaft wall parts 21 on both ends of the U-shaped locking ring 20 can automatically partially exit from the mortise lock shaft cavity a under the pushing of the unlocking spring 101, so that automatic unlocking is realized; this also indicates that the lock has been unlocked and the unlocking person can easily fully withdraw the shackle 20 from the mortise lock shaft cavity a.

Therefore, the functions of automatic unlocking and free locking of the padlock can be realized by the cooperation of the unlocking spring 101 and the micro trigger switch.

In order to make the rotation of the first driving wheel 51 smoother, (refer to fig. 7-9), a positioning shaft 512 is formed on the front end surface of the first driving wheel 51 of the present embodiment and extends forward along the direction of the output shaft of the driving motor 50, a positioning shaft groove d is formed on the inner wall of the lock body 10 and aligned with the positioning shaft 512, and the front end shaft of the positioning shaft 512 is rotatably connected in the positioning shaft groove d. Therefore, the cooperation of the positioning shaft 512 and the positioning shaft groove d can be utilized to respectively position the two ends of the first driving wheel 51 between the driving motor 50 and the inner wall of the lock body 10, so that the first driving wheel 51 can rotate more smoothly while being limited, and the normal operation of the device is effectively ensured.

Further, in order to optimize the structure of the device, (refer to fig. 5-8), the elastic component of the present embodiment includes a first spring 103 and a second spring 104, the first slider 30 includes a first tab 31 distributed at the outer end for aligning and matching with the locking notch b and a first overlapping portion 32 formed by extending inward from the inner end wall surface of the first tab 31, and the first unlocking notch 301 is opened at the first overlapping portion 32; the second slider 40 comprises a second locking tongue portion 41 distributed at the outer end and used for matching with another locking notch b in an alignment manner, and a second overlapping portion 42 formed by extending the inner end wall surface of the second locking tongue portion 41 inwards, the second unlocking notch 401 is opened at the second overlapping portion 42, and the first overlapping portion 32 and the second overlapping portion 42 are distributed in a parallel overlapping manner; the first spring 103 is arranged between the inner end wall surface of the first tongue-locking portion 31 and the inner end wall surface of the second overlapping portion 42, and two ends of the first spring 103 are respectively abutted against the inner end wall surface of the first tongue-locking portion 31 and the inner end wall surface of the second overlapping portion 42; the second spring 104 is disposed between the inner end wall surface of the second tongue-locking portion 41 and the inner end wall surface of the first overlapping portion 32, and both ends of the second spring 104 respectively abut against the inner end wall surface of the second tongue-locking portion 41 and the inner end wall surface of the first overlapping portion 32. Therefore, the first spring 103 and the second spring 104 can be used to automatically drive the first latch portion 31 and the second latch portion 41 to move to the outer ends distributed on both sides, so that the function of locking by automatically moving to the locking notch b along the distribution direction of the first overlapped part 32 and the second overlapped part 42 can be realized. Of course, the two ends of the first spring 103 and the second spring 104 are not limited to be disposed between the first slider 30 and the second slider 40, and may be disposed between the first slider 30 and the inner wall of the lock body 10 and between the second slider 40 and the inner wall of the lock body 10, as long as the first slider 30 and the second slider 40 can be driven to move outward from the two ends, respectively.

Further, in order to enable the padlock to unlock the locks with the key at the same time, (refer to fig. 4-8), the U-shaped padlock of this embodiment further includes a key lock head 70, the key lock head 70 is installed in the lock body 10 along a direction parallel to the output shaft of the driving motor 50, a second driving wheel 71 is disposed at the front end of the key lock head 70, a third unlocking notch 302 and a fourth unlocking notch 402, which are at least partially overlapped and distributed, are further respectively disposed on the first overlapping portion 32 and the second overlapping portion 42, the front end of the second driving wheel 71 is a flat column structure, and the front end of the second driving wheel 71 sequentially extends into the third unlocking notch 302 and the fourth unlocking notch 402 and is distributed; when the second driving wheel 71 is driven by the key cylinder 70 to rotate, the front end of the second driving wheel 71 is in a flat column structure to press the side wall surfaces of the third unlocking notch 302 and the fourth unlocking notch 402, so that the first slider 30 and the second slider 40 respectively overcome the elastic force of the elastic component and move inwards along the distribution direction thereof to exit the lock notch b. Based on the above structural arrangement, the principle that the second driving wheel 71 cooperates with the third unlocking notch 302 and the fourth unlocking notch 402 to drive the first slider 30 and the second slider 40 to lock and unlock is basically the same as the cooperation principle of the first driving wheel 51 with the first unlocking notch 301 and the second unlocking notch 401, so the positions of the key lock head 70 and the driving motor 50 can be interchanged; meanwhile, if the key lock head 70 is damaged or the driving motor 50 is not powered, the normal operation of the other unlocking mechanism cannot be influenced, and although one key unlocking mechanism is added, the structural change of the first sliding block 30 and the second sliding block 40 is not large, the first sliding block 30 and the second sliding block 40 are convenient to process and assemble, the structure of the lockset is greatly simplified, and the production cost is reduced.
