[0031] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all embodiments. Based on the embodiments given, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0032] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the purpose of facilitating the description of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0033] In the description of the present application, the terms "first", "second" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated.

[0034] For details Figures 1-15As shown, the application discloses a kind of transmission structure of intelligent padlock, including lock body 10, lock beam 20, identity recognition component, open and close lock component 50 and built-in rechargeable battery 70 preferably 18650 lithium battery, of course, It also includes NFC identification component built in lock body 10 in the drawing is not shown.This embodiment is preferably, open and close lock component 50 includes locking assembly 51, locking assembly 51 includes ball cam 511 and multiple balls 512, ball cam 511 is provided with notch 5111;Lock body 10 is provided with ball channel 11a;First lock beam stop groove 221 is set on the short side 22 of lock beam 20, ball 512 is movably arranged in ball channel 11a, and located between ball cam 511 and short side 22;Rotating ball cam 511, to push ball 512 to first lock beam stop groove 221 inside, and make it part by the opening end of ball channel 11a to explore outside, keep embedded in first lock beam stop groove 221;At this time, since ball 512 keeps being inserted in first lock beam stop groove 221, short side 22 of lock beam 20 will be limited in lock beam hole, therefore, padlock is in locked state, cannot be opened.Only when ball cam 511 is reversed or continues to rotate ball cam 511, make the notch 5111 of ball cam 511 turn to the position opposite ball channel 11a, at this time, the outer periphery of ball cam 511 no longer extrudes ball, the action force of ball 512 is eliminated, short side has the tendency of moving up, the sidewall of first lock beam stop groove 221 will extrude ball 512, in turn drive ball 512 to move from first lock beam stop groove 221 to ball channel 11a, when ball 512 is completely removed from first lock beam stop groove 221, the short side of lock beam is locked, lock beam can be moved upwards, so that short side is removed from lock beam hole, at this time padlock is opened.

[0035] Further, in order to significantly improve the locking reliability of the locking beam 20 and better improve the ability of the padlock to resist violent disassembly, the embodiment preferably has a second locking beam stop groove 212 on the long side 21 of the locking beam 20. The two sides of the ball cam 511 are provided with ball bearings 512 between the long side 21 and the short side 22. The ball cam 511 is symmetrically provided with a notch 5111. Rotate the ball cam 511 to push the ball bearings 512 to move into the first locking beam stop groove 221 and the second locking beam stop groove 212, respectively, and make part of them respectively protrude outward from the two open ends of the ball bearing channel 11a, and keep embedded in the first locking beam stop groove 221 and the second locking beam stop groove 212. When and only when the force of the ball cam 511 on the ball bearings 512 is eliminated, the ball bearings 512 can move out of the first locking beam stop groove 221 and the second locking beam stop groove 212. At this time, since the ball bearings 512 are kept stuck in the first locking beam stop groove 221 and the second locking beam stop groove 212, the short side 22 and the long side 21 of the locking beam 20 are respectively limited in the short side locking beam hole 113 and the long side locking beam hole 112. At this time, the padlock is in a locked state and cannot be opened. When and only when the ball cam 511 is rotated in the opposite direction or continues to be rotated, the notch of the ball cam 511 is turned to the position opposite to the ball bearing channel 11a. At this time, the ball cam 511 no longer presses the ball bearings, the force on the ball bearings 512 is eliminated, and the short side 22 and the long side 21 have a tendency to move upward. The sidewalls of the first locking beam stop groove 221 and the second locking beam stop groove 212 will press the ball bearings 512, thereby driving the ball bearings 512 to move from the first locking beam stop groove 221 and the second locking beam stop groove 212 into the ball bearing channel 11a. When the ball bearings 512 are completely removed from the first locking beam stop groove 221 and the second locking beam stop groove 212, the locking of the short side and the long side of the locking beam is released, and the locking beam 20 can move upward, so that the short side 22 moves out of the short side locking beam hole 113. At this time, the padlock is opened. In order to prevent the ball bearings 512 from rolling out of the opening end of the ball bearing channel 11a after moving out of the short side locking beam hole 113, the embodiment preferably has a limiting part 11b at the opening end of the ball bearing channel 11a. The limiting part 11b is provided with a necked structure at the opening end of the ball bearing channel 11a, which can only make less than half of the ball bearings 512 protrude outward, thereby limiting the ball bearings 512 from coming out of the opening end. Of course, in order for the ball bearings 512 to be better embedded, the first locking beam stop groove 221 and the second locking beam stop groove 212 are preferably circular in cross-section and less than half a circle, so that the ball bearings can be fully embedded and fitted in the first locking beam stop groove 221 and the second locking beam stop groove 212, and can also smoothly move out of the first locking beam stop groove 221 and the second locking beam stop groove 212, improving the smoothness of the lock.

[0036] In order to directly expand outward at the moment of unlocking, so as to smoothly unlock, and also make the most intuitive feedback for unlocking, the embodiment is preferably provided with a elastic assembly 59 in the long side hole 112 of the lock beam, which is located at the bottom of the long side hole 112 of the lock beam, and the upper end of the elastic assembly 59 abuts against the lower end of the long side 21 of the lock beam. During the movement of the lock beam 20 into the lock body and locking, the long side 21 will compress the elastic assembly 59, at this time, the elastic force of the elastic assembly 50 will act on the long side 21 of the lock beam 20, and keep it outwardly pressed along the axial direction. Then, when the lock beam is unlocked at the moment, the elastic assembly 50 will outwardly press the long side 21, so as to make the entire lock beam pop up, realize quick unlocking, and also make the most direct feedback for the unlocking success action compared with the padlock without the elastic assembly 50.

[0037] After unlocking, the bottom of the short side 22 of the lock beam is away from the lock body 10, and the long side 21 of the lock beam is still in the lock body 10. When the short side 22 of the lock beam is not aligned with the short side hole 113 in the unlocking state, the entire lock beam 20 is pressed downward, and the second lock beam stop groove 212 of the long side 21 of the lock beam cooperates with the ball 512 to lock the lock beam 20, so that the false lock phenomenon occurs. Therefore, as shown in Figures 4-6 and Figure 14 The embodiment is preferably provided with a limiting plate 83 on the cover plate 80, and the long side 21 of the lock beam is provided with a positioning part 213 on the outer circumferential surface facing the limiting plate 83. The lower end of the long side 21 is provided with a ring groove 211 at a position below the positioning plane 213. When the lock beam 20 moves outward to the position where the ring groove 211 is aligned with the limiting plate 83, the lock beam 20 can rotate around the long side 21 as the shaft. Only when the short side 22 is aligned with the lock beam hole and the limiting plate 83 is aligned with the positioning part 213, the lock beam 20 can continue to be pressed into the lock body 10, so that the short side 22 is inserted into the lock beam hole. At the same time, due to the existence of the ring groove 211, the limiting plate 83 is clamped into the ring groove 211, and the entire lock beam 20 can still rotate freely and smoothly by 360°. However, only after the positioning part 213 is aligned with the positioning part 213, the lock beam can be pressed downward, so that the short side can be inserted into the short side lock beam hole, and locked, thereby solving the false lock problem.

[0038] In the embodiment, a power assembly and the rotating shaft 52 are further included. The power assembly applies a rotating torque to the rotating shaft 52 to drive the ball cam 511 to rotate by a set angle in a set direction. Specifically, the power assembly includes an electric actuator 53 and a lock cylinder 54. The electric actuator 53 and the lock cylinder 54 can drive the rotating shaft 52 to rotate, respectively. The electric actuator 53 relies on the password interaction assembly 30, the fingerprint identification assembly 40, and the NFC identification assembly to authenticate the identity information of a user. The electric actuator 53 is controlled by an internal microcontroller to rotate a motor of the electric actuator 53, thereby driving the rotating shaft 52 to rotate, and further driving the ball cam 511 to rotate. The lock cylinder 54 is inserted into a lock hole of the lock cylinder 54 by a mechanical key, thereby driving the lock cylinder 54 to rotate, and further driving the rotating shaft 52 to rotate. Specifically, the electric actuator 53 includes a motor and a speed reduction gear set, which drives the rotating shaft 52 through a first transmission assembly 55. The first transmission assembly 55 includes a first cam portion 551 provided on the rotating shaft 52, and a first eccentric wheel 552 provided on an output end of the speed reduction gear set of the electric actuator 53. An outer circumferential surface of the first eccentric wheel 552 is in contact with an outer circumferential surface of the first cam portion 551. When the power assembly is driven to rotate, the first eccentric wheel 552 is pressed against the first cam portion 551. When the motor of the electric actuator 53 is powered and rotates in a forward direction, the first eccentric wheel 552 pushes the first cam portion 551 to rotate, thereby driving the rotating shaft 52 to rotate, and further driving the ball cam 511 to rotate to perform an unlocking action. Subsequently, the electric actuator 53 is reversed to drive the motor cam 552 to return to the initial position. In order to enable the ball cam 511 to return to the initial position when the electric actuator 53 returns to the initial position, the embodiment further includes a reset torsional spring 57. A spring portion of the reset torsional spring 57 is sleeved on the rotating shaft, one free end of the reset torsional spring 57 is clamped on the rotating shaft cam 551, and the other free end of the reset torsional spring 57 abuts against the locking body 11. The reset torsional spring 57 has a preset elastic force. When the electric actuator 53 drives the rotating shaft 52 to rotate, the reset torsional spring 57 is further twisted and deformed. When the electric actuator 53 returns to the initial position, the motor cam 552 no longer pushes the rotating shaft cam 551, that is, the force acting on the rotating shaft 52 is eliminated. The reset torsional spring 57 drives the rotating shaft 52 and the ball cam 511 to rotate reversely to the initial position. Of course, the lock cylinder 54 drives the rotating shaft 52 through a second transmission assembly 56. The second transmission assembly 56 includes a second eccentric wheel 562 and a second cam portion 561 in the embodiment. The second eccentric wheel 562 is fixedly arranged on the lock cylinder, and the second cam portion 561 is fixedly arranged on the rotating shaft 52. The working principle of the second transmission assembly 56 for driving the rotating shaft 52 to rotate is the same as that of the first transmission assembly 55, which is not described herein again. In order to ensure the reliable reset of the rotating shaft 52, the reset torsional spring 57 is further arranged at a position close to the second transmission assembly 56, thereby further enhancing the reset reliability of the rotating shaft.Since the rotation flexibility of the rotating shaft 52 is crucial to the unlocking of the power assembly and the reduction of the driving force requirement of the reset torsion spring 57, in the present embodiment, a bearing seat 58 is arranged near the positions of the two ends of the rotating shaft 52, and a bearing is arranged between the rotating shaft 52 and the bearing seat 58. Then, through the arrangement of the bearing, the rotation flexibility of the rotating shaft can be greatly increased, the requirement of the driving force can be reduced, and the problem of the rotation jamming during the rotation can be well avoided, thus causing the unlocking failure.

[0039] As shown in Figure 4 、 Figures 10-15 , in the present embodiment, the lock body 10 comprises an upper lock body 11, a connecting shell 13, a lower lock body 14 and an outer shell 12. The connecting shell 13 is located between the upper lock body 11 and the lower lock body 14, and the outer shell 12 is sleeved outside the upper lock body 11. Specifically, as shown in Figure 4 、 Figure 10 and Figure 11As shown, the upper lock body 11 has a second accommodating cavity 114 and a ball channel 11a on one side; the lock beam long side hole 112 and the lock beam short side hole 113 are arranged on the end surface of the upper lock body 11 perpendicular to the side surface of the second accommodating cavity 114, and the second accommodating cavity 114 communicates with the lock beam long side hole 112 and the lock beam short side hole 113 through the ball channel 11a; the opening and closing lock assembly is installed in the second accommodating cavity 114 and the ball channel 11a; the long side and the short side of the lock beam 20 are respectively inserted into the lock beam long side hole 112 and the lock beam short side hole 113. Among them, the second accommodating cavity 114 has a rotating shaft accommodating cavity 1141, a bearing mounting cavity 1142, a first transmission assembly and a second transmission assembly accommodating cavity 1143, an electric actuator accommodating cavity 1144, and a lock cylinder through hole 1145; then the rotating shaft 52, the rotating shaft bearing 58, the first transmission assembly 55 and the second transmission assembly 56, the electric actuator 53 and the lock cylinder 54 are respectively installed in the rotating shaft accommodating cavity 1141, the bearing mounting cavity 1142, the first transmission assembly and the second transmission assembly accommodating cavity 1143, the electric actuator accommodating cavity 1144 and the lock cylinder through hole 1145, and a silica gel sealing sleeve 831 is sleeved on the electric actuator 53, so as to separate the space of the mechanical part at the front end of the electric actuator 53 and the space of the wire connection part at the rear end in the electric actuator accommodating cavity 1144, avoiding the influence of water vapor on the electrode wire of the electric actuator 53. It also includes a cover plate 80, the cover plate 80 is provided with a first protrusion 81 and a second protrusion 82, the top surface of the first protrusion 81 has an arc-shaped groove with a radius slightly larger than that of the ball, the first protrusion 81 is buckled on the ball channel 11a, and the completed ball channel is formed by the arc-shaped groove and the ball channel 11a; the second protrusion 82 has an arc-shaped groove with the same outer diameter as the bearing, so that the second protrusion 82 can press the bearing tightly in the bearing mounting cavity 1142; of course, in order to facilitate the positioning of the cover plate 80 when installing the cover plate 80 on the upper lock body 11, the sealing gasket 85 is arranged between the upper lock body 11 and the cover plate 80, so as to seal the second accommodating cavity 114 and the ball channel 11a, in order to make the first protrusion and the second protrusion not be affected by the sealing gasket 85 during installation, a corresponding avoiding channel 851 is preferably arranged on the sealing gasket 85 in the embodiment, so that the first protrusion and the second protrusion can be directly buckled on the ball channel 11a and the bearing mounting cavity 1142 through the avoiding channel 851 during installation.Thus, in use, due to the need for a moving gap, external water vapor will inevitably enter the ball channel 11a and the second accommodating cavity 114 through the lock beam long side hole 112 and the lock beam short side hole 113. However, due to the communication structure in this embodiment, the entering water vapor can be discharged outward along the lock beam long side hole 112 and the lock beam short side hole 113 under the action of evaporation, and can also be discharged downward through the key hole of the lock cylinder installed at the lock cylinder through hole 1145. It should be noted that the second accommodating cavity 114 is located on the side of the upper lock body 11 away from the first accommodating cavity 11c, thereby achieving dry and wet separation, thereby solving the problem that the entire cavity inside the traditional padlock is filled with water vapor entering through the lock beam long side hole 112 and the lock beam short side hole 113, and the circuit board is also placed in the cavity, which poses a threat to the circuit board. Figure 11 As shown, the upper lock body 11 is provided with a battery accommodating cavity 1146 on the side away from the second accommodating cavity 114, and a recessed cavity is excavated downward in a material-removing manner, which is in communication with the battery accommodating cavity 1146. The rechargeable battery 70 is received in the battery accommodating cavity 1146.

[0040] In addition, see Figures 1-2 , Figure 4 and Figures 7-9As shown, in the embodiment, the identity recognition assembly comprises a password interaction assembly 30, a fingerprint recognition assembly 40 and a control circuit board 16; the password interaction assembly 30, the fingerprint recognition assembly 40 and the control circuit board 16 are all arranged in the shell assembly 17, and the input keyboard 31 of the password interaction assembly 30 and the fingerprint recognition end 41, i.e. the fingerprint sensor of the fingerprint recognition assembly 40, are exposed outward through the channels on the shell assembly 17, and the input keyboard and the fingerprint recognition end are provided with a sealing structure with the channels; specifically, the shell assembly 17 comprises a lower shell 1711 and an upper shell 1712, the upper shell 1712 is provided with an input keyboard channel 1712b and a fingerprint recognition channel 1712a, the input keyboard 31 is provided with a keyboard waterproof sleeve 32, the fingerprint recognition end 41 is peripherally provided with a waterproof silica gel ring 42, the upper shell 1712 is fixedly connected with the lower shell 1711 through screws, and the keyboard waterproof sleeve 32 and the waterproof silica gel ring 42 are pressed on the channels, so that the sealing between the input keyboard and the fingerprint recognition end and the input keyboard channel 1712b and the fingerprint recognition channel 1712a is realized, and thus the shell assembly 17 is obtained after assembly. Then, as shown in FIGS. 5-6, the shell 12 is sleeved on the outside of the upper lock body 11 from the end of the upper lock body 11 away from the lock beam 20, and is surrounded with the recessed area c on one side of the upper lock body 11 to form a first accommodating cavity 11c, and the accommodating cavity 11c is open outward from the end away from the lock beam 20; the shell assembly 17 is inserted into the first accommodating cavity 11c from the open end of the accommodating cavity 11c; of course, in order to facilitate the insertion of the shell assembly 17, the depth of the first accommodating cavity 11c is slightly greater than the thickness of the shell assembly 17, in order to solve the sealing problem between the shell 12 and the shell assembly 17, the embodiment preferably provides that the flexible sealing material 172 is arranged between the shell assembly 17 and the shell 12; however, due to the convenience of assembly, the depth of the first accommodating cavity 11c is slightly greater than the thickness of the shell assembly 17, which makes it difficult for the flexible sealing material 172 to achieve good sealing, therefore, after the shell assembly 17 is inserted into the first accommodating cavity 11c, a plug 18 is inserted between the shell assembly 17 and the first accommodating cavity 11c through the opening to extrude the shell assembly 17, and then the shell assembly 17 extrudes the flexible sealing material 172 to the shell 12, thereby realizing the sealing performance of the flexible sealing material 172. Of course, the first channel 121 and the second channel 122 are arranged on the shell 12, the first channel 121 and the second channel 122 expose the input keyboard and the fingerprint recognition end to the outside of the shell 12, so that the password input and fingerprint recognition operation can be performed from the outside of the padlock.It should be noted that during the reuse process, the padlock will be jolted or vibrated.
