[0042] The active electronic lock 1 of the embodiment of the present disclosure is used to seal the sealed object B, and can cooperate with an automatic locking device or an automatic sealing system to automatically lock and seal the sealed corner B.

[0043] like Figures 1 to 5 As shown, the active electronic lock 1 includes a first lock body 11 , a second lock body 12 , a strap 13 and a strap operating mechanism 14 .

[0044] The first lock body 11 includes a first housing 111 and a first locking portion 112 disposed on the first housing 111 .

[0045] The second lock body 12 includes a second housing 121 and a second locking portion disposed on the second housing 121. The first lock body 11 and the second lock body 12 have a locked state and an unlocked state. In the locked state, the first locking portion 112 engages with the second locking portion; in the unlocked state, the first locking portion 112 and the second locking portion disengage.

[0046] Two ends of the binding strap 13 are connected to the first lock body 11 and the second lock body 12 respectively.

[0047] The strap control mechanism 14 is disposed within the first housing 111 and is used to restrict the movement of the strap 13. The strap control mechanism 14 is configured to: in a locked state, control the strap 13 to retract into the first housing 111 but not to withdraw from the first housing 111; in an unlocked state, control the strap 13 to retract into the first housing 111 and withdraw from the first housing 111.

[0048] The active electronic lock 1 of the disclosed embodiment has two lock bodies, a first lock body 11 and a second lock body 12, and a strap 13 integrated together. When sealing an object B, the two lock bodies 11 and 12 can be separated by external force, allowing the strap 13 to be drawn out from the corresponding lock body and wrapped around the object. After the strap 13 has wrapped around the object B and the two lock bodies 11 and 12 are locked, the strap 13 can be retracted and cannot be withdrawn after retraction. The active electronic lock 1 has a compact structure and is easy to operate, facilitating the automatic sealing operation of the object B by an automatic locking device or an automatic sealing system, thereby saving labor costs.

[0049] It should be noted that the so-called "encirclement" in the embodiment of the present disclosure is that as long as the strap 13 can be wrapped around the sealed object B, such as suspicious luggage, the encircling path is not limited, for example, it can be a combination of a circular path, an elliptical path, a polygonal path, a curved path and a straight path.

[0050] like Figure 4 and Figure 5 As shown, in some embodiments of the active electronic lock 1 , the strap operating mechanism 14 includes a strap shaft 141 , a ratchet 142 and a pawl 143 .

[0051] The belt shaft 141 is connected to the first housing 111 and is used to wrap the strap 13. One end of the strap 13 is fixedly connected to the belt shaft 141 and connected to the first lock body 11 through the belt shaft 141. The ratchet 142 is connected to the belt shaft 141 for preventing rotation.

[0052] When the first lock body 11 and the second lock body 12 are in a locked state, the ratchet 142 and the pawl 143 are in an engaged state so that the ratchet 142 can rotate in one direction. When the first lock body 11 and the second lock body 12 are in an unlocked state, the ratchet 142 and the pawl 143 are in a disengaged state so that the ratchet 142 can rotate in both directions.

[0053] The connection between the ratchet wheel 142 and the belt shaft 141 is not limited to any specific connection method, as long as the two are in a non-rotatable state so that the belt shaft 141 rotates and the ratchet wheel 142 rotates, and the ratchet wheel 142 restricts the belt shaft 141 from unidirectional rotation when engaged with the pawl 143. For example, the rotation-proof connection between the two can be achieved by welding, key connection, form fit, etc.

[0054] When the ratchet 142 and the pawl 143 are in an engaged state, the unidirectional rotation of the ratchet 142 can lock the ratchet 142 in the direction in which the strap 13 is withdrawn, thereby preventing the belt shaft 141, which is connected to the ratchet 142 for rotation, from rotating. The strap 13 cannot be withdrawn from the first shell 111. However, since the ratchet 142 can rotate in the opposite direction, it does not affect the retraction of the strap 13 into the first shell 111. When the ratchet 142 and the pawl 143 are in a disengaged state, since the ratchet 142 can rotate in both directions, the ratchet 142 and the pawl 143 basically do not restrict the rotation of the belt shaft 141. At this time, the strap 13 can be withdrawn from the first shell 111 under the action of an external force, or it can be wound around the belt shaft 141 under the action of a third reset mechanism 148 located in the first shell 111 or a screw control unit 147 connected to the belt shaft 141, which will be described in detail later, thereby retracting it into the first shell 111.

[0055] like Figure 1As shown, to achieve linkage between the first locking portion 112 and the pawl 143 and thus control the strap 13, the first locking portion 112 of the first lock body 11 includes a telescopic locking rod 1122 that is linked to the pawl 143. In the locked state, the telescopic locking rod 1122 is retracted, and the ratchet 142 and the pawl 143 are in a meshed state. In the unlocked state, the telescopic locking rod 1122 is extended, and the ratchet 142 and the pawl 143 are disengaged.

[0056] In order to enable the telescopic locking rod 1122 to automatically reset, in some embodiments, such as Figure 4 As shown, the first locking portion 112 includes a first reset mechanism 1123 , and the first reset mechanism 1123 is configured to apply a force to the telescopic locking rod 1122 to cause the telescopic locking rod 1122 to extend.

[0057] The first reset mechanism 1123 may be, for example, a compression spring. Figure 4 As shown, a connecting plate is provided on the bottom wall of the first shell 111, the first end of the telescopic locking rod 1122 extends from the through hole on the first shell 111, and the second end is sleeved in the compression spring and limited by the limiting portion, and the other end of the compression spring is pressed against the connecting plate, so that the compression spring can apply a force to the telescopic locking rod 1122 to cause the telescopic locking rod 1122 to extend.

[0058] like Figure 4 As shown, in some embodiments of the active electronic lock 1, the strap control mechanism 14 further includes a follower portion 144 and a mating portion 145. The follower portion 144 is connected to the telescopic lock rod 1122 and moves synchronously with the telescopic lock rod 1122. The mating portion 145 is connected to the pawl 143 and mating with the follower portion 144 to actuate under the action of the follower portion 144 and drive the pawl 143 to move.

[0059] The following portion 144 and the matching portion 145 can make the linkage setting between the telescopic lock rod 1122 and the pawl 143 more flexible, with fewer restrictions on the structure and relative position of the telescopic lock rod 1122 and the pawl 143, and can also easily achieve accurate positioning of the ratchet 142 and the pawl 143 in the engaged state and the disengaged state, thereby ensuring the reliability of the strap control mechanism 14 in limiting the movement of the strap 13. Figures 1 to 5 In the embodiment shown, the limiting portion and the following portion 144 for limiting the second end compression spring sleeved on the telescopic locking rod 1122 can be an integral structure. Of course, the limiting portion and the following portion can also be set as separate structures.

[0060] like Figure 4 As shown, in some embodiments of the active electronic lock 1 , the follower 144 includes a guide groove 1441 .

[0061] The fitting portion 145 includes a guide rod that is movably disposed in a direction perpendicular to its length within the guide slot 1441. The guide rod is preferably circular in cross section and is configured as a guide shaft, but may be of other shapes as long as its function is achieved.

[0062] like Figure 4 As shown, in some embodiments of the active electronic lock 1 , the strap operating mechanism 14 includes a second reset mechanism 146 , which applies a force to the pawl 143 to move the pawl closer to the ratchet 142 so as to engage with the ratchet 142 .

[0063] In this embodiment, the pawl 143 is hinged to the inner wall of the first housing 111 via a hinge shaft. The second return mechanism 146 can be a torsion spring mounted on the hinge shaft. The two ends of the torsion spring can be connected to the hinge shaft and the pawl 143 respectively, thereby applying a force to the pawl 143 to move it closer to the ratchet 142. When the telescopic lock rod 1122 is extended outward from the first housing 111 under the action of the compression spring, the pawl 143 is rotated by the cooperation of the guide rod and the guide slot 1441, causing the pawl to move away from the ratchet 142, thereby separating the ratchet 142 and the pawl 143.

[0064] like Figures 1 to 4 As shown, in some embodiments of the active electronic lock 1, the strap control mechanism 14 includes a screwing control portion 147, which is connected to the belt shaft 141 and is used to screw the belt shaft 141 to tighten the strap 13. The connection method between the screwing control portion 147 and the belt shaft 141 is not limited, as long as the screwing control portion 147 can drive the belt shaft 141 to rotate so that the strap 13 is retracted into the first housing 111. In this embodiment, the screwing control portion 147 includes a hexagonal head, which can be used in conjunction with a screwing tool with a hexagonal head. The screwing tool may include a motor to drive the hexagonal head to rotate to achieve automatic operation. Of course, the structure of the screwing control portion 147 can be other forms, for example, it can be other shapes such as an inner square head, a semicircular groove, or it can also be a screwing control portion with other forms such as an outer hexagonal head, an outer pentagonal head, or a semicircular head.

[0065] like Figure 4 and Figure 5 As shown, in some embodiments of the active electronic lock 1 , the strap operating mechanism 14 further includes a third reset mechanism 148 . The third reset mechanism 148 is configured to apply a force to the strap 13 to cause the strap 13 to automatically retract into the first housing 111 .

[0066] like Figure 4 and Figure 5 As shown, the third restoring mechanism 148 may include an elastic element connected to the belt shaft 141 for winding the strap 13. The elastic element may include a coil spring, for example.

[0067] like Figure 4 As shown, in some embodiments of the active electronic lock 1 , the strap control mechanism 14 may further include a transmission mechanism 149 , and the third reset mechanism 148 is connected to the belt shaft 141 for winding the strap 13 via the transmission mechanism 149 .

[0068] like Figure 4 In the illustrated embodiment, the transmission mechanism 149 includes a first gear 1491 and a second gear 1492 that mesh with each other. A coil spring, serving as the third reset mechanism 148, is wound around the gear shaft of the first gear 1491, which is mounted within the first housing 111. The second gear 1492 is mounted on the belt shaft 141. Thus, the coil spring, via the first gear 1491 and the second gear 1492, can apply a force to the belt shaft 141 that tends to rotate the belt shaft 141, causing the belt shaft 141 to rotate in a direction that causes the strap 13 to be wound around it. The belt shaft 141 then causes the strap 13 to be wound around it, thereby applying a force that tends to retract the strap 13 into the first housing 111.

[0069] like Figure 4 As shown, in some embodiments of the active electronic lock 1 , the active electronic lock 1 further includes a positioning chip 15 . The positioning chip 15 is disposed in the first housing 111 or the second housing 121 and is configured to track the position of the active electronic lock 1 in real time.

[0070] like Figure 4 As shown, in some embodiments of the active electronic lock 1, the active electronic lock 1 also includes a locking part sensing switch 16, which is arranged in the first shell 111 or the second shell 121. The locking part sensing switch 16 is configured to determine whether the first locking part 112 and the second locking part are fully matched to improve the success rate of sealing.

[0071] like Figure 5 As shown, in some embodiments of the active electronic lock 1, the active electronic lock 1 further includes a sealed object sensing switch 17, which is disposed on the first shell 111 or the second shell 121. The sealed object sensing switch 17 is configured to determine whether the active electronic lock 1 is separated from the sealed object B.

[0072] like Figure 4 and Figure 5 As shown, in some embodiments of the active electronic lock 1, the active electronic lock 1 also includes a rechargeable battery 181 arranged in the first shell 111 or the second shell 121 and a charging interface 182 arranged on the shell where the rechargeable battery 181 is located and electrically connected to the rechargeable battery 181. The rechargeable battery 181 is configured to supply power to the electrical components of the active electronic lock 1.

[0073] The active electronic lock 1 of the embodiment of the present disclosure can realize the functions of locking, binding and sealing the sealed object B, such as suspicious luggage, by integrating the two lock bodies 11 and 12 and the strap 13, thereby improving the locking and sealing efficiency, and can be used in conjunction with an automatic locking device or an automatic sealing system to reduce labor costs.

[0074] The following combination Figures 1 to 5 The embodiments of the present disclosure are described in more detail.

[0075] The active electronic lock 1 is generally divided into three parts: a first lock body 11 , a second lock body 12 and a binding strap 13 .

[0076] The first lock body 11 and the second lock body 12 are connected by a strap 13. A warning sign or slogan may be printed on the strap 13. The first lock body 11 includes a first shell 111 and a first locking portion 112 provided on the first shell 111. The first locking portion 112 includes a fixed lock rod 121 provided on the first shell 111 and located on the opposite side of the strap 13 and fixed relative to the first shell 111, and a telescopic lock rod 122 that is telescopic relative to the first shell 111. The fixed lock rod 121 is fixed to the first shell 111 and includes a rod segment located inside the first shell 111 and a rod segment located outside the first shell 111. The telescopic lock rod 1121 is as described above.

[0077] The second lock body 12 includes a second housing 121 and a second locking portion provided on the second housing 121. Figure 4 and Figure 5 As shown, the second locking portion is disposed on the opposite side of the connecting strap 13 of the second housing 121. The second locking portion includes a first locking hole 1221 provided on the second housing 121, corresponding to the fixed locking rod 1121, and a second locking hole 1222 corresponding to the telescopic locking rod 1122. The second locking portion also includes a lock core 1223 disposed within the second housing 121, corresponding to the first locking hole 1221, and a baffle 1224 disposed within the second housing 121, corresponding to the second locking hole 1222. The lock core 1223 is provided with a locking hole that mates with the fixed locking rod 1121. When the first and second lock bodies 11 and 12 are locked from the unlocked state, the fixed locking rod 1221 passes through the first locking hole 1221 and mates with the locking hole of the lock core 1223. The telescopic locking rod 1122 passes through the second locking hole 1222 and abuts against the baffle 1224. The baffle 1224 then retracts the telescopic locking rod 1122 from its extended position into the first housing 111. The fixed locking rod 1121 may be provided with a groove for cooperating with the lock core 1223 when locking.

[0078] The first housing 111 of the first lock body 11 and the second housing 121 of the second lock body 12 provide support for the internal structures and installation of components of the first lock body 11 and the second lock body 12 .

[0079] A strap control mechanism 14 is provided inside the first housing 111 of the first lock body (11). The strap control mechanism 14 includes a belt shaft 141. One end of the strap 13 extends through a first opening 1111 on the first housing 111 into the first housing 111 and is fixedly connected to the belt shaft 141 located in the first housing 111. The other end of the strap 13 extends through a second opening 1211 provided on the second housing 121 and is fixedly connected to the interior of the second housing 121. The strap 13 can be rolled up around the belt shaft 141 and stored inside the first lock body 11.

[0080] A coil spring is provided within the first housing 111 of the first lock body 11 as a third reset mechanism 148. The gear train, acting as a transmission mechanism 149, engages and drives the belt shaft 141 to rotate, automatically winding the stretched strap 13 around the belt shaft 141 and retracting it into the first lock body 11. The gear train includes a first gear 1491 and a second gear 1492 meshing with the first gear 1491. The coil spring is wound around the gear shaft of the first gear 1491. The second gear 1492 is mounted on the belt shaft 141. The coil spring tightens as the strap 13 is withdrawn from the first housing 111. Thereafter, in the absence of external force separating the first and second lock bodies 11 and 12, or in the absence of sufficient external force, the coil spring drives the belt shaft 141 to rotate via the gear train, thereby winding the strap 13 around the belt shaft 141 and automatically retracting the strap 13.

[0081] A ratchet 142 is provided at the other end of the belt shaft 141, and a pawl 143 is provided on the same side inside the first shell 111 of the first lock body 11. When the active electronic lock 1 is opened, the pawl 143 and the ratchet 142 are in a separated state, the belt shaft 141 can rotate in both directions, and the strap 13 can be extended, pulled out, rolled up, and retracted; when the active electronic lock 1 is locked (the first lock body 11 and the second lock body are in a locked state), the pawl 143 engages with the ratchet 142, the belt shaft 141 can only rotate in one direction, and the strap 13 can only be rolled up and retracted, but cannot be extended or pulled out.

[0082] The belt shaft 141 is provided with an inner hexagon head serving as a screwing control part 147, and the belt shaft 141 can be driven to rotate by rotating the inner hexagon head. After the active electronic lock 1 is tied to the sealed object B, the strap 13 can automatically retract to fit the sealed object B after the external force applied by the automatic locking device disappears. The strap 13 can be further tightened by applying external force by screwing the control part 147, which helps prevent the active electronic lock 1 from falling off.

[0083] The telescopic locking rod 1122 can be telescopically moved, and a compression spring is provided at its end as a first reset mechanism 1123. When the active electronic lock 1 is opened, the telescopic locking rod 1122 is in an extended state. When the active electronic lock 1 is tied and locked, the telescopic locking rod 1122 is restricted by the baffle 1224 and retracts into the first shell 111 of the first lock body 11.

[0084] The telescopic movement of the telescopic locking rod 1122 drives the rotation of the pawl 143. When the first lock body 11 and the second lock body 12 are in the unlocked state, the telescopic locking rod 1122 disengages from the baffle 1224. Under the action of the compression spring, the telescopic locking rod 1122 extends, driving the pawl 143 to rotate away from the ratchet 142. The pawl 143 and the ratchet 142 are separated, and the belt shaft 141 can rotate in both directions. When the first lock body 11 and the second lock body 12 are in the locked state, the telescopic locking rod 1122 retracts under the action of the baffle 1224. The guide groove 1441 and the third return mechanism 146 rotate the pawl 143 toward the ratchet 142. When the telescopic locking rod 1122 retracts to the extreme position, the pawl 143 engages with the ratchet 142, and the belt shaft 141 can only rotate in one direction. Correspondingly, at this time, the strap 13 can only be rolled up and cannot be extended.

[0085] A guide slot 1441 is provided on the follower portion 144 of the telescopic lock rod 1122. A guide rod serving as a mating portion 145 is correspondingly provided in the middle of the pawl 143. The guide rod engages with the guide slot 1441. When the telescopic lock rod 1122 is extended, the pawl 143 and the ratchet 142 are disengaged; when the telescopic lock rod 1122 is retracted, the pawl 143 engages with the ratchet 142. The guide rod is mounted in the middle of the pawl 143 and extends toward one side of the telescopic lock rod 1122 to engage with the guide slot 1441.

[0086] The pawl 143 is hinged to the bottom wall of the first shell 111 through a hinge shaft, and a torsion spring is installed on the hinge shaft as a second reset mechanism 146. When the telescopic lock rod 1122 is in a retracted state, the second reset mechanism 146 applies force to the pawl 143 to engage with the ratchet 142, so that the belt shaft 141 can only rotate in one direction.

[0087] A positioning chip 15 is disposed inside the second housing 121 of the second lock body 12 , such as a UWB (Ultra Wide Band) positioning chip, which can track the position of the active electronic lock 1 in real time.

[0088] A locking portion sensing switch 16 is further provided inside the second housing 121 of the second lock body 12. When the active electronic lock 1 is locked, the fixed lock rod 1121 triggers the locking portion sensing switch 16 to feedback that the first lock body 11 and the second lock body 12 are in a locked state.

[0089] The second lock body 12 is provided with a sealed object sensing switch 17 at the bottom. When the lock body is tied to the surface of the luggage, the sealed object sensing switch 17 is triggered to feedback whether the active electronic lock 1 is separated from the sealed object B, such as suspected luggage.

[0090] A rechargeable battery 181 is housed within the second housing 121 of the second lock body 12. This battery provides power to the various electrical components of the active electronic lock 1. For example, the rechargeable battery 181 can be used to power the positioning chip 15, the locking sensor switch 16, and the sealed object sensor switch 17, enabling the active electronic lock 1 to operate independently. A charging port 182 is provided on the second housing 121 for charging the rechargeable battery 181.

[0091] The locking process of active electronic lock 1 is as follows:

[0092] When the active electronic lock 1 is in the initial state, the first lock body 11 and the second lock body 12 are in the unlocked state, the first locking portion 112 and the second locking portion of the first lock body 11 and the second lock body 12 are in contact with each other, and the strap 13 is rolled up and stored inside the first shell 111.

[0093] When locking, the first lock body 11 or the second lock body 12 rotates around the sealed object B for one circle, or the first lock body 11 and the second lock body 12 rotate around the sealed object B respectively, and rotate around the sealed object B together for one circle, and the first lock body 11 and / or the second lock body 12 drive the strap 13 to be pulled out from the first shell 111 under tension, stretch and rotate around the sealed object B for one circle.

[0094] The second lock body 12 rotates relative to the first lock body 11 until the first locking portion 112 and the second locking portion are opposite to each other, and the fixed locking rod 1121 and the telescopic locking rod 1122 on the first locking portion 112 of the first lock body 11 are respectively inserted into the corresponding first locking hole 1221 and second lock body 1222 of the second locking portion 112 of the second lock body 12, so that the first lock body 11 and the second lock body 12 are in a locked state.

[0095] Finally, the belt shaft 141 can be rotated by rotating the screwing control part 147 with external force to tighten the binding belt 13, thereby binding the active electronic lock 1 to the sealed object B more firmly.

[0096] When using the active electronic lock 1 of the disclosed embodiment, it can be connected to the backend monitoring system to lock, seal, and tag the sealed object B, such as suspected luggage. Once locked and sealed, the backend monitoring system immediately begins monitoring the suspected luggage. After a passenger retrieves the suspected luggage from the Baggage Handling System (BHS), they cannot open it themselves. After the passenger completes a personal declaration or clears the suspected luggage, the active electronic lock 1 will be opened by staff.

[0097] After suspicious luggage is locked and sealed, multiple alarm functions can be implemented, including, for example, alarms for illegal access, exiting the electronic fence area, entering a sensitive area, and abnormal lock status. For example, if the active electronic lock is equipped with a positioning chip 15, it can track the real-time location of the sealed suspicious luggage. If the suspected luggage crosses the boundary, the active electronic lock 1 can send relevant information to the backend, triggering an alarm for exiting the electronic fence area or entering a sensitive area. For another example, the active electronic lock 1 can include both a tampering sensor and an alarm buzzer. When the sealed suspicious luggage is opened, the buzzer will sound an alarm, and the information about the opened luggage and the location of the opening will be pushed to the backend staff.

[0098] The two first lock bodies 11 and the second lock body 12 and the binding strap 13 of the active electronic lock 1 of the embodiment of the present disclosure are integrated together, which has a compact structure and is easy to operate, is conducive to the operation of the automatic locking device, and can save labor costs.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not intended to limit them. Although the present disclosure has been described in detail with reference to preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present disclosure can still be modified or some technical features can be replaced by equivalents, which should all be included in the scope of the technical solutions claimed for protection in the present disclosure.
