[0047] Please refer to Figure 5and Fig. 6, Figure 5 As shown in Fig. 6, Figure 1 As shown in Fig. 6, Figure 5 As shown in Fig. 6, Figure 6A As shown in Fig. 6, Figure 6B As shown in Fig. 6, The modular lock cylinder 17 comprises a middle cylinder 172, a mechanical lock cylinder 173, a locking device 175, a driving member 177 and a resilient member 179. The middle cylinder 172 combines and fixes the locking device 175, the resilient member 179, the driving member 177 and the mechanical lock cylinder 173 as an integrated structure. The locking device 175 is in active connection with the driving member 177 and the mechanical lock cylinder 173. The password recognition device 13 controls the locking or unlocking of the locking device 175 through the driving member 177. Alternatively, the mechanical lock cylinder 173 cooperates with a corresponding key. A user rotates the key to drive the mechanical lock cylinder 173 to trigger the locking or unlocking of the locking device 175.

The third opening 1724 is arranged at the second end 1722. The maintenance opening 1725 and the wire hole 1726 are arranged opposite to each other.

[0049] As shown in Fig. 6, Figure 5 As shown in Fig. 6, The basic structure of the mechanical lock cylinder 173 is known to those skilled in the art, such as a pin tumbler lock cylinder or a blade lock cylinder. Therefore, the following is a brief description: The inner wall of the lock cylinder hole 1727 corresponds to the structure of the mechanical lock cylinder 173 and is provided with a groove capable of accommodating a lateral pin mechanism or a pin mechanism or a leaf spring mechanism. When the key is inserted into the lock hole of the mechanical lock cylinder 173, the key teeth of the key press the lateral pin mechanism or the pin mechanism or the leaf spring mechanism, which is pushed into the groove, so that the other structure of the mechanical lock cylinder 173 can rotate relative to the lock cylinder hole 1727.

[0050] It should be noted that the other end of the mechanical lock cylinder 173 is an output end relative to the lock hole end of the mechanical lock cylinder 173, the output end of the mechanical lock cylinder 173 exposes the first end 1721 of the middle bin 172 and is movably connected with the locking device 175. In the case of no key matching, the output end of the mechanical lock cylinder 173 is not connected with the locking device 175; in the case of key matching, when the mechanical lock cylinder 173 is rotated relative to the lock cylinder hole 1727, the output end of the mechanical lock cylinder 173 abuts against the locking device 175 and transmits the rotating torque to the locking device 175, thereby changing the locking or unlocking state of the locking device 175. The mechanical lock cylinder 173 can be a cylindrical lock cylinder, a cross lock cylinder or a double tongue lock cylinder, etc. In this embodiment, the mechanical lock cylinder 173 is a cylindrical lock cylinder.

[0068] It can be understood that, in order to improve the structural stability, in the embodiment, the size of the fixing plate 131 is greater than that of the control board 135, a plurality of screw holes are reserved along the normal direction of the first direction, and the password recognition device 13 is fixedly connected to the modular lock cylinder 17 through bolt fixing.

[0069] The fixing plate 131 and the waterproof part 133 are provided with a through hole 139 corresponding to the fingerprint identification unit 1351 of the control plate 135. The fingerprint identification unit 1351 is exposed through the through hole 139 and the second opening 119, and the acquisition sensor 121 of the fingerprint sensing part 12 is electrically connected.

[0070] The fingerprint identification unit 1351 can be an MCU chip. In this embodiment, the fingerprint identification unit 1351 is an MCU module including an STC89C52 single-chip microcomputer, a DSP image processing chip, and a SE security encryption chip.

[0071] Please refer to Figure 2 and Figure 5 The lock beam 19 is substantially U-shaped, including a long arm portion 191, a short arm portion 193, and a cross beam 195. The cross beam 195 connects the long arm portion 191 and the short arm portion 193. The long arm portion 191 is provided with a first locking groove 1911 for accommodating the first marble 17531, and the short arm portion 193 is provided with a second locking groove 1931 for accommodating the fourth marble 17534. The elastic part 179 is sleeved on one end of the long arm portion 191 close to the second end 1722, and provides an upward stress for the lock beam 19.

[0072] Specifically, one side of the first marble 17531 abuts against the inner wall of the first locking groove 1911, and the other side abuts against the second marble 17532. One side of the fourth marble 17534 abuts against the inner wall of the second locking groove 1931, and the other side abuts against the third marble 17533.

[0073] Please refer to Figure 11 , Figure 11 For Figure 1 The working principle diagram of the intelligent padlock is shown in FIG. 1. In order to show the working relationship between the modular lock cylinder and the lock beam and the driving part, part of the components of the intelligent padlock are not shown in the figure. It can be understood that the modular lock cylinder is still a modular integrated structure in the actual assembly process. The working principle of the intelligent padlock 1 is as follows:

[0074] When the lock needs to be opened, the password is input to the password identification device 13, and in this embodiment, the password is in the form of a fingerprint. The control panel 135 judges that the input password is correct, and further controls the rotation of the driving member 177. Since the limiting member 1754 is movably connected with the driving member 177, the limiting member 1754 is further driven to rotate, so that the two arc concave structures 175411 are respectively turned to the second and third elastic balls 17532 and 17533; at the same time, since the elastic member 179 provides an upward force to the lock beam 19, the long and short arm portions of the lock beam 19 respectively generate a force to the elastic ball set 1753, which is directed to the limiting member 1754. The force of the two parts makes the first, second, third and fourth elastic balls 17531, 17532, 17533 and 17534 move towards the two arc concave structures 175411. When the first and fourth elastic balls 17531 and 17534 respectively leave the first and second locking grooves 1911 and 1931, the lock beam 19 is ejected from the modular lock cylinder 17, and the unlocking of the intelligent padlock is realized.

[0075] It should be noted that in order to deal with unexpected situations, such as failure of the fingerprint collection sensor or the fingerprint recognition unit, a corresponding key can also be inserted into the mechanical lock cylinder 173 to complete the unlocking, and the unlocking principle has been described above.

[0076] When the lock needs to be locked, an external stress is applied to the lock beam 19 downward; at the same time, the limiting member 1754 is rotated under the action of the elastic potential energy of the reset member 1755, so that the second and third elastic balls 17532 and 17533 respectively leave the two arc concave structures, and further push the first and fourth elastic balls 17531 and 17534 to be respectively accommodated in the first and second locking grooves. At this time, the first and second locking grooves 1911 and 1931, the first, second, third and fourth elastic balls 17531, 17532, 17533 and 17534, and the limiting member 1754 are arranged in a straight line, and the locking of the intelligent lock is realized.

[0077] Please refer to Figure 2 , the complete assembly process of the intelligent padlock is as follows: the first fixing member 112 cooperates with the front shell 111 to form the accommodating groove 1125, and the fingerprint sensing member 12 is inserted into the accommodating groove 1125 through the opening 1127 and is clamped and fixed.

In order to prevent violent disassembly and artificial destruction of the intelligent padlock, the modular lock cylinder 17 is further provided with a wedge-shaped groove in communication with the internally threaded hole 170, and the center line of the wedge-shaped groove 1701 intersects the center line of the internally threaded hole 170. After the nut is received in the wedge-shaped groove 1701, the wedge-shaped block 1703 is used to hold and fix the nut so that the nut cannot rotate freely.

[0080] The rear cover 113 is installed on one side of the outer surface of the modular lock cylinder 17 and is arranged opposite to the password recognition device 13. The bolt is screwed into the fixing hole 1131 and the internally threaded hole 170, and the rear cover 113 is fixedly installed on the modular lock cylinder 17 through the bolt connection of the bolt and the nut.

[0082] Subsequently, the lock beam 19 is installed on the combined assembly of the front shell 111, the password recognition device 13, the modular lock cylinder 17 and the rear cover 113, wherein the long arm portion 191 is received in the receiving groove 1720, and the short arm portion 193 is received in the fixing hole 1131 and covers the bolt connection position. If the correct password cannot be input, the short arm portion of the lock beam 19 is ejected, the lock beam 19 will hinder the disassembly of the shell 11, and the protection safety of the intelligent padlock is improved.

[0083] The battery compartment 15 is partially received in the second receiving space 1723 through the fourth opening 114 and the third opening 1724, so that the battery compartment 15 and the front shell 111 cooperate to hold the modular lock cylinder 17. The outer cover 1513 of the battery compartment 15 has a threaded hole. After the battery and the battery compartment 15 are installed, the battery compartment 15, the front shell 111 and the modular lock cylinder 17 are fixed together by bolts. At this point, the smart padlock assembly is completed. Its assembly operation is simple and the assembly process is efficient, which significantly reduces the production management cost of the smart padlock and improves the product yield.
