DETAILED DESCRIPTION

[0025] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0026] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] See also Figures 1 to 8 As shown, the present invention provides a smart padlock and a lock system. The smart padlock includes a lock housing 1, a lock rod 2, and a lock core 3 disposed in the lock housing 1. The lock core 3 includes an electric component 31, a manual component 32, and a locking plug plate 33. The electric component 31 of the locking plug plate 33 is disposed in the lock housing 1 and can move between a locked position clamped with the lock rod 2 and an unlocked position unclamped from the lock rod 2; the electric component 31 and the manual component 32 are disposed in the lock housing 1, and the electric component 31 is connected to the locking plug plate 33 to drive the locking plug plate 33 to move between the locked position and the unlocked position; the manual component 32 is disposed in the lock housing 1, and the manual component 32 is connected to the locking plug plate 33 to at least be suitable for driving the locking plug plate 33 to move from the locked position to the unlocked position under the action of an external force. The electric component 31 includes a rotating push block 311, and the locking plug plate 33 has a receiving groove 331 that cooperates with the rotating push block 311. The rotating push block 311 is connected to the receiving groove 331 and can move in the receiving groove 331. The rotational movement of the rotating push block 311 drives the locking plug plate 33 to move between the locking position and the unlocking position. When the locking plug plate 33 is in the locking position, the rotating push block 311 and the receiving groove 331 are in non-dead point contact, so that the manual component 32 can drive the locking plug plate 33 to move toward the unlocking position and drive the rotating push block 311 to rotate.

[0028] In the smart padlock provided by the present invention, when the locking plate 33 is in the locking position, the rotating push block 311 driven by the electric component 31 is in non-dead point contact with the accommodating groove 331 on the locking plate 33, so that the manual component 32 can drive the locking plate 33 to move to the unlocking position and push the rotating push block 311 to rotate, which can realize emergency unlocking, has a simple structure, is easy to operate, and improves the safety and reliability of the use of the smart padlock.

[0029] See also Figures 1 to 3As shown, the lock housing 1 comprises a rear housing 11 and a front housing 12, and the lock core 3 is located in a cavity surrounded by the rear housing 11 and the front housing 12. An electronic key hole 13 and a mechanical key hole 14 are provided on the bottom surface of the lock housing 1, wherein the electronic key hole 13 is associated with the electric component 31 for inserting an electronic key to realize electric unlocking and electric locking; the mechanical key hole 14 is associated with the manual component for inserting a mechanical key to realize manual unlocking and locking.

[0030] The electric component 31 includes a motor having a motor shaft, and the rotating push block 311 is connected to the motor shaft and is eccentrically arranged relative to the motor shaft. In this way, when the motor shaft rotates, the movement path of the rotating push block 311 is an arc. In the present embodiment, the rotating push block 311 includes an integrally formed connection base, which is sleeved on the motor shaft and relatively fixed to the motor shaft in the circumferential direction. In other embodiments, the rotating push block 311 can also be set as a cam structure directly connected to the motor shaft. It can be understood that the electric component 31 can also include electrical components such as circuit boards.

[0031] In this embodiment, the lock core 3 is a passive lock core 3, in other words, the electric component 31 does not include a power supply. This can avoid the inconvenience of setting up and replacing a power supply on the padlock, and at the same time enable the smart padlock to be used in harsh environments without worrying about power supply damage or shortened life. The electronic keyhole 13 included in the smart padlock is exposed to the lock shell 1, and the electronic keyhole 13 is provided with terminals that can transmit power and control signals to the electric component 31. When the electronic key is plugged into the electronic keyhole 13, the power supply and control unit in the electronic key can transmit power and control signals to the smart padlock through the terminals provided in the electronic keyhole 13 to drive the electric component 31 to work, thereby realizing electric unlocking and electric locking.

[0032] The locking plug plate 33 has a receiving groove 331 that cooperates with the rotating push block 311. The receiving groove 331 is a long strip-shaped through groove. The rotating push block 311 is connected to the receiving groove 331 and maintains contact with the two side walls of the receiving groove 331 in the width direction. The rotational movement of the rotating push block 311 drives the locking plug plate 33 to translate and slide between the locking position and the unlocking position.

[0033] See also Figure 7As shown, the manual component 32 includes a fork shaft 323 and a fork column 3231 disposed on the fork shaft 323, the fork column 3231 is eccentrically disposed relative to the central axis of the fork shaft 323, and the locking plug plate 33 is provided with a slot 332 for accommodating the fork column 3231. The cooperation between the slot 332 and the fork column 3231 is configured such that when the locking plug plate 33 moves between the locking position and the unlocking position under the drive of the electric component 31, the slot 332 does not contact the fork column 3231. When the locking plug plate 33 is in the locking position, the fork column 3231 is close to the side wall of the slot 332 away from the end that the lock rod 2 can open and close. The bottom end of the manual component 32 has a mechanical key hole 14 for inserting a mechanical key, and the manual component 32 is driven to rotate by the mechanical key, wherein the electric component 31 is close to the end of the lock rod 2 that can be opened and closed, and the manual component 32 is far away from the end of the lock rod 2 that can be opened and closed.

[0034] See also Figures 4 to 6 As shown, Figure 4 and Figure 5 In the embodiment, the manual component 32 remains stationary, and when the locking plug plate 33 moves between the locking position and the unlocking position under the drive of the electric component 31, the slot 332 and the fork column 3231 are always out of contact during the movement; when the electric component 31 fails in the locking position and cannot be unlocked, such as Figure 5 and Figure 6 As shown, at this time, the fork column 3231 is driven by the mechanical key Figure 5 Move to the indicated position Figure 6 The position shown in the figure is realized by pushing the locking plug plate 33 from the locking position to the unlocking position; and in order to prevent the force applied by the rotating push block 311 of the electric component 31 to the locking plug plate 33 from affecting the movement of the locking plug plate 33, when the locking plug plate 33 is in the locking position, the rotating push block 311 and the receiving groove 331 are in non-dead point contact. The so-called non-dead point contact means that when the locking plug plate 33 moves from the locking position to the unlocking position, the force applied to the rotating push block 311 can generate a torque that causes the rotating push block 311 to rotate. In other words, the force arm of the force is not zero.

[0035] For further information, see Figure 1 , Figure 7 and Figure 8 As shown, the manual component 32 is constructed to be suitable for use with an emergency key 51 and a reset key 52. ​​The manual component 32 has a movable pin 324 therein. When the emergency key 51 drives the manual component 32 to rotate, the movable pin 324 falls from an initial position to a locked position to prevent the emergency key 51 from being used again. The movable pin 324 is reset to its initial position under the push of the reset key 52.

[0036] Specifically, the manual component 32 includes a bottom column 321, a locking column 322, a shift fork shaft 323, a movable pin 324 and a spring 325. The locking column 322 is fixed in the lock housing 1 and cannot rotate. A first locking groove 3221 and two second locking grooves 3222 are provided at the top of the locking column 322. The central angles of the two second locking grooves 3222 are 180°, and the central angles of one first locking groove 3221 and any of the two second locking grooves 3222 are 90°. There are two movable pins 324, which are installed in the shift fork shaft 323. In this embodiment, the movable pin 324 is a locking column, and a spring 325 is provided between the locking column and the shift fork shaft 323.

[0037] The mechanical key includes an emergency key 51 and a reset key 52. ​​The difference between the emergency key 51 and the reset key 52 is that the emergency key 51 has a low slot 511 and a high slot 512 on both sides of the top, while the reset key 52 has no slot. The low slot 511 is a slot with a relatively deep slot depth, and the high slot 512 is a slot with a relatively shallow slot depth.

[0038] The positions of the two movable pins 324 of the smart padlock when it leaves the factory are as follows: Figure 7 As shown in the figure, one movable pin 324 is in the first lock groove 3221, and the other movable pin 324 is not in any lock groove; when the emergency key 51 is inserted, the high-level slot 512 of the emergency key 51 pushes out the movable pin 324 in the first lock groove 3221, and at this time the fork shaft 323 can rotate relative to the locking column 322, and when rotated 90°, the two movable pins 324 move to the positions of the two second lock grooves 3222, and the movable pins 324 corresponding to the low-level slot 511 fall into the second lock groove 3222 under the action of the spring 325 without support; after the emergency key 51 is pulled out, the two movable pins 324 both fall into the two second lock grooves 3222; when the emergency key 51 is used again afterwards, since the low-level slot 511 cannot lift up the movable pin 324, it cannot drive the fork shaft 323 to move, that is, the emergency key 51 can only unlock once and then become invalid. At this time, the reset key 52 is required to reset the movable pin 324. The reset key 52 can lift up the two movable pins 324 at the same time. At this time, the fork shaft 323 can be rotated to achieve reset. During management, the reset key 52 is controlled by the manufacturer, and the electronic key and emergency key 51 are handed over to the user. Usually, the electronic key is mainly used to unlock. When unlocking, a signal will be transmitted to the manufacturer's backend via wireless for easy monitoring; if the electric component 31 fails, the user can use the emergency key 51 to unlock, but the smart padlock will be locked after the emergency key 51 is used once and cannot be used. It needs to be returned to the manufacturer for reset to ensure safety.

[0039] The present invention also provides a lock system, which includes an electronic key, a mechanical key and the smart padlock as described above, wherein the electronic key is configured with a power supply and a control unit, and the electronic key is used to contact the smart padlock for power supply and transmission of locking and unlocking signals.

[0040] From the above description of the specific embodiments, it can be known that the smart padlock provided by the present invention includes an electric component 31 and a manual component 32. Both the electric component 31 and the manual component 32 can act on the locking plug plate 33, and when the locking plug plate 33 is in the locked position, the rotating push block 311 driven by the electric component 31 is in non-dead point contact with the accommodating groove 331 on the locking plug plate 33, so that at this time the manual component 32 can drive the locking plug plate 33 to move to the unlocked position and push the rotating push block 311 to rotate, which can realize emergency unlocking, and has a simple structure and is easy to operate, thereby improving the safety and reliability of the use of the smart padlock.

[0041] The present invention is described by several specific embodiments, and it should be understood by those skilled in the art that various changes and equivalent substitutions may be made to the present invention without departing from the scope of the present invention. In addition, various modifications may be made to the present invention for specific situations or specific circumstances without departing from the scope of the present invention.
