Description

[0002] With the development of the national economy and science and technology, the logistics industry is becoming increasingly prosperous. In the traditional logistics transportation process, cargo boxes rely on traditional locks to prevent the cargo boxes from being illegally opened. With the development of science and technology, the technology level of locks used in logistics is becoming higher and higher. Smart locks with remote unlocking, location tracking, Bluetooth unlocking and other functions are also becoming more and more popular in the logistics industry.

[0003] While the existing smart locks for logistics have improved their own technological level, they have ignored the safety performance of traditional mechanical unlocking methods. The technological functions of smart locks mostly rely on the network. When the logistics box is in an environment with poor signal or signal shielding, most of its technological functions will fail and cannot play a protective role. The logistics box can only rely on traditional mechanical unlocking methods to protect it. In the traditional mechanical unlocking method, the unlocking action can be completed by an adapted key, while in the ignored mechanical unlocking method, the structure of the mechanical key is relatively simple, and the difficulty and cost of imitation are relatively low, and it is impossible to provide good safety protection in the process of logistics transportation.

[0021] Please refer to the appendix Figures 1 to 5As shown, this is the first embodiment of the present invention. This embodiment provides a highly secure logistics intelligent lock based on remote control operation, including a housing 100, a limit module 200, a mechanical module 300, and an intelligent module 400.

Inside the sealing base 120, a power supply element 140 is fixed.

[0022] Furthermore, a plurality of solar panels 141 are assembled on the outside of the housing 100, and a charging interface 142 is assembled at the lower end of the sealing base 120. The charging interface 142 can be any one of the following interfaces: micro-USB interface, type-c interface, Lightning interface, or other interfaces with charging and data transmission functions. And both between the power supply element 140 and the solar panels 141, and between the charging interface 142 and the power supply element 140 are electrically connected through wires. Through the above solution, the power supply element 140 can be charged, facilitating the long-term operation of the device. A controller is also assembled between the power supply element 140 and the solar panels 141. Through this controller, light energy can be converted into electrical energy and the electrical energy can be stored.

[0023] Please refer to Figure 6 As shown, the limit module 200 includes a slider 210, a limit block 220, a first elastic element 230, a second elastic element 240, a limit rod 250, and a third elastic element 260.

The limit rod 250 is slidably connected inside the base block 110. The limit rod 250 is adapted to the curved mating surface 221, and the lower end of the limit rod 250 is connected to the intelligent module 400. The third elastic element 260 is assembled between the limit rod 250 and the base block 110. When the limit module 200 is in the limiting state, the limit module 200 forms a limit on the lock ring 130, making the lock ring 130 and the housing 100 in a locked state.

[0024] Among them, the mechanical module 300 can unlock the locked state between the lock ring 130 and the housing 100 in a mechanical way, and the intelligent module 400 can unlock the locked state between the lock ring 130 and the housing 100 in a wireless communication way.

[0025] It should be noted that there is also a remote control server used in conjunction with the intelligent module 400. A wireless communication module is integrated in the intelligent module 400, and the wireless communication module is connected to the remote control server through a wireless signal. The intelligent module 400 can be remotely controlled through the remote control server. Specifically, the above technical solution is a mature existing application, and its specific working principle can refer to the existing technology, and no further elaboration will be made here.

[0026] In this embodiment, when the device is in the locked state, the curved mating surface 221 at one end of the limiting block 220 is in contact with the limiting rod 250, and the limiting end on the limiting block 220 is located inside the locking groove on the locking ring 130. The slider 210 limits the locking ring 130. At this time, the limiting module 200 is in the limiting state, and the housing 100 and the locking ring 130 are in the locked state. When unlocking is required, the locking state between the housing 100 and the locking ring 130 can be released mechanically through the mechanical module 300, or the locking state between the housing 100 and the locking ring 130 can be released wirelessly through the intelligent module 400.

[0027] Further, please refer to Figures 7 to 10 As shown, the mechanical module 300 is assembled inside the base block 110. The mechanical module 300 includes a lock core part 310 and a key part 350. The lock core part 310 includes a first driving element 311, a limiting pin 312, a lock body 313, a shaft core 314, a driving block 315, a telescopic touch pin assembly 316, and a plurality of pin assemblies 317. The lock body 313 is fixed inside the base block 110. The first driving element 311 is fixed inside the lock body 313, and the first driving element 311 is electrically connected to the intelligent module 400 through a wire. The limiting pin 312 is fixed to the output end of the first driving element 311. The shaft core 314 is rotatably connected inside the lock body 313. A plurality of through holes are provided on the shaft core 314. The driving block 315 is fixed to one end outside the shaft core 314, and an avoidance groove adapted to the driving block 315 is provided on the lock body 313. The telescopic touch pin assembly 316 is fixed to the side wall of the lock body 313, and the telescopic touch pin assembly 316 is electrically connected to the power supply element 140 through a wire. A plurality of pin assemblies 317 are all assembled between the lock body 313 and the shaft core 314, and the plurality of pin assemblies 317 are in one-to-one correspondence with the plurality of through holes, and the limiting pin 312 and the through holes. An arc-shaped avoidance groove 318 adapted to the telescopic touch pin assembly 316 is provided on the shaft core 314, and a first spacer 319 is fixed inside the arc-shaped avoidance groove 318.

[0028] Please refer to Figures 11 to 12As shown in the figure, the key part 350 further includes a first key strip 351, a second key strip 352, a hand-held handle 353, a second driving element 354, a linkage rod 355 and a fourth elastic element 356. The first key strip 351 is movably inserted into the inner part of the shaft core 314. One end of the second key strip 352 is slidably connected to the inside of the first key strip 351, and one end of the second key strip 352 extends to the outside of the first key strip 351. The hand-held handle 353 is fixed to the end of the first key strip 351 away from the second key strip 352. The second driving element 354 is fixed to the inside of the hand-held handle 353. The second driving element 354 and the intelligent module 400 are electrically connected through a wire. The linkage rod 355 is fixed to the output end of the second driving element 354, and one end of the linkage rod 355 extends into the inside of the first key strip 351 and is fixedly connected to the second key strip 352. The fourth elastic element 356 is assembled between the hand-held handle 353 and the linkage rod 355. A second spacer 357 is fixed to the bottom of the first key strip 351. Two conductive contact blocks 358 and two conductive contact pieces 359 are fixed to the inside of the second spacer 357. The conductive contact blocks 358 are adapted to the telescopic contact pin assembly 316. Both ends of the conductive contact piece 359 are respectively connected to the conductive contact block 358 and the second driving element 354.

[0029] Here, the materials of the first spacer 319 and the second spacer 357 are both insulating materials. When the mechanical module 300 is in the unlocked state, the telescopic contact pin assembly 316 is in contact with the first spacer 319. Through the above solution, it can be avoided that when the unlocking or locking action is performed, the telescopic contact pin assembly 316 contacts the metal element, causing a short circuit in the circuit.

[0030] Specifically, the tumbler assembly 317 at least includes a spring, an upper tumbler and a lower tumbler. A plurality of tooth grooves are formed on both the first key strip 351 and the second key strip 352. The plurality of tooth grooves are respectively adapted to the plurality of lower tumblers. When the plurality of tooth grooves are in contact with the plurality of lower tumblers one by one, the upper tumbler is located inside the lock body 313 and the lower tumbler is located inside the shaft core 314. At this time, the shaft core 314 can rotate relative to the lock body 313.

[0031] Further, a pin rod 360 is fixed to the bottom of the first key strip 351, and a guide groove 361 is formed in the bottom of the second key strip 352. The pin rod 360 is adapted to the guide groove 361. Through the above solution, the moving direction of the second key strip 352 can be restricted, so that the tooth groove at the upper end of the second key strip 352 can be accurately adapted to the lower tumbler.

[0032] It should be noted that both the first driving element 311 and the second driving element 354 are bidirectional holding round tube electromagnets or other driving elements with self-locking functions. In this embodiment, preferably a bidirectional holding round tube electromagnet, which is a mature existing technology. The product is internally provided with a coil and a permanent magnet. When the bidirectional holding round tube electromagnet is not powered on, the sliding rod has a holding force under the action of the permanent magnet. When a positive current is applied to the bidirectional holding round tube electromagnet, the coil generates a magnetic field to overcome the action of the permanent magnet and produces a displacement with only an instantaneous current. When the sliding rod moves to the end, it is held at the other end under the action of the permanent magnet. When a reverse current is applied to the bidirectional holding round tube electromagnet, the coil generates a force to overcome the action of the permanent magnet and moves back to the original position, and the electromagnet completes a complete work cycle.

[0033] In this embodiment, please refer to Figure 13 and Figure 15 As shown in the figure, when it is necessary to mechanically release the locked state between the housing 100 and the lock ring 130 through the mechanical module 300, the key part 350 is inserted into the lock core part 310. After the first key strip 351 is completely inserted into the shaft core 314, the conductive contact block 358 and the telescopic contact pin assembly 316 are in contact. At this time, the lower end of the limit ball 312 is located inside the shaft core 314, and the limit ball 312 forms a limit on the second key strip 352. The second key strip 352 retracts inside the first key strip 351, and a closed circuit is formed among the power supply element 140, the first driving element 311, the second driving element 354, and the intelligent module 400. The intelligent module 400 activates the first driving element 311, causing the first driving element 311 to operate. The output end of the first driving element 311 drives the limit ball 312 to move into the lock body 313, so that the limit ball 312 releases the limit on the second key strip 352. At the same time, the intelligent module 400 activates the second driving element 354, causing the output end of the second driving element 354 to drive the linkage rod 355 to move. Since the linkage rod 355 is fixedly connected to the second key strip 352, the linkage rod 355 drives the second key strip 352 to move until the second key strip 352 moves to the farthest position from the handle 353. At this time, the tooth grooves on the first key strip 351 and the second key strip 352 are respectively adapted to a plurality of lower balls, and the shaft core 314 can rotate relative to the lock body 313.

[0034] Please refer to Figure 14As shown in the figure, rotate the hand-held handle 353. The hand-held handle 353 drives the first key strip 351, the second key strip 352, and the shaft core 314 to rotate. Due to the fixed connection between the shaft core 314 and the drive block 315, the shaft core 314 drives the drive block 315 to rotate. When the upper end of the drive block 315 fits against the lower end of the limit block 220, the drive block 315 drives the limit block 220 to rotate. After the limit block 220 rotates, it squeezes the first elastic element 230. When the first elastic element 230 is squeezed, the curved mating surface 221 and the limit rod 250 no longer fit. At this time, the limit block 220 changes from the limit state to the free state, releasing the restriction of the slider 210 on the lock ring 130. Pull the outer shell 100, causing the lock ring 130 to move relative to the outer shell 100. After the lock ring 130 moves, it drives the slider 210 to move and squeezes the second elastic element 240, thereby releasing the locked state between the outer shell 100 and the lock ring 130 and completing the unlocking action.

[0035] When a locking action is required, rotate the hand-held handle 353 in the reverse direction. The hand-held handle 353 drives the shaft core 314, the drive block 315, the first key strip 351, and the second key strip 352 to reset. Press the outer shell 100, causing the lock ring 130 to move in the reverse direction relative to the outer shell 100, so that the lock ring 130 resets. The drive block 315 and the limit block 220 are disengaged. The limit block 220 resets under the action of the first elastic element 230, and the slider 210 resets under the action of the second elastic element 240. When the limit end on the slider 210 moves into the locking groove on the lock ring 130 again, the limit module 200 forms a limit on the lock ring 130 again, thereby forming a locked state between the outer shell 100 and the lock ring 130 again. Through the above solution, the complexity of the mechanical unlocking method is increased, and thus the safety performance of the device is improved.

[0036] Please refer to Figure 5 As shown in the figure, the intelligent module 400 includes an integrated circuit board 410, a third driving element 420, and an eccentric wheel 430. The integrated circuit board 410 is assembled on the upper end of the sealed base 120. The integrated circuit board 410 is at least integrated with a wireless communication module, a processing element, a GPS module, and a storage module. And there are electrical connections between the integrated circuit board 410 and the power supply element 140, between the integrated circuit board 410 and the first driving element 311, and between the integrated circuit board 410 and the second driving element 354 through wires. The third driving element 420 is fixed inside the base block 110, and the eccentric wheel 430 is fixed to the output end of the third driving element 420. The lower end of the limit rod 250 fits against the surface of the eccentric wheel 430.

[0037] Further, the integrated circuit board 410 is electrically connected to the charging interface 142 through a wire. While the power supply component 140 can be charged through the charging interface 142, data can also be transmitted. Among them, the wireless communication module is assembled on the integrated circuit board 410.

[0038] Specifically, the normally closed state means that when the eccentric wheel 430 rotates to the upper outer position of the third driving element 420, the third driving element 420 drives the limiting rod 250 and the limiting block 220 to fit together. At this time, the intelligent module 400 is in a closed state.

[0039] It should be noted that there are also multiple wireless terminals used in conjunction with the device. The wireless terminal can be one or more of the following terminals: a radio frequency card, a mobile client, a software client, or other wireless terminals that can start the third driving element 420 through a wireless signal.

[0040] Among them, after the key part 350 is inserted into the lock core part 310, a closed circuit is formed among the power supply component 140, the first driving element 311, the second driving element 354, and the integrated circuit board 410. The integrated circuit board 410 drives the first driving element 311 to operate and releases the limit formed by the limit ball 312 on the second key strip 352.

[0041] Here, the wireless communication module is used to receive wireless signals, the processing element is used to process wireless signals and issue corresponding instructions, the GPS module is used for spatial positioning, and the storage module is used for storing information.

[0042] In this embodiment, wireless signal transmission can be carried out through the wireless communication module. The spatial position of the device can be located through the GPS module, and the spatial position of the device can be transmitted through the wireless communication module. Through the wireless terminal used in conjunction, the position of the device can be understood in real time. The received wireless signals can be processed through the processing element. When an unlocking operation is performed through the wireless terminal, after the wireless communication module receives the unlocking instruction, it starts the third driving element 420, causing the third driving element 420 to drive the eccentric wheel 430 to rotate, so that the eccentric wheel 430 rotates from the upper outer position of the third driving element 420 to the lower outer position of the third driving element 420. At the same time, under the action of the third elastic element 260, the limiting rod 250 moves in the direction close to the third driving element 420, and then the limiting rod 250 disengages from the limiting block 220 and no longer forms a limit on the limiting block 220, thus completing the unlocking operation. In a specific embodiment, when the device is applied to logistics transportation, the device can be unlocked through the wireless terminal, and the position of the logistics can also be understood in real time.

[0043] In a preferred embodiment, an information interaction component may also be provided on the outer shell 100. The information interaction component and the integrated circuit board 410 are electrically connected through wires. The information interaction component is used to display the state of the device. The state display component can be any one or more of the following components: a lighting component, a sound component, a display screen, or other components capable of displaying the device state.

[0044] The working principle of the present invention is as follows: When remote unlocking of the device is required, an unlocking instruction is sent through a wireless terminal. After the integrated circuit board 410 receives the unlocking instruction, the third driving component 420 is started, and the eccentric wheel 430 is driven to rotate by the third driving component 420. At the same time, under the action of the third elastic component 260, the limiting rod 250 and the limiting block 220 are disengaged, and the limiting of the limiting block 220 is no longer formed. The staff near the device pulls the outer shell 100, so that the lock ring 130 moves relative to the outer shell 100, and the unlocking action can be completed. At the same time, the state of the logistics can be understood through the wireless terminal; When the staff near the device needs to perform an unlocking action, the key part 350 is inserted into the interior of the shaft core 314. After the first key strip 351 is completely inserted into the shaft core 314, a closed circuit is formed among the power supply component 140, the first driving component 311, the second driving component 354, and the integrated circuit board 410. The first driving component 311 and the second driving component 354 are started through the integrated circuit board 410, so that the second key strip 352 moves to a specified position. After the tooth grooves on the first key strip 351 and the second key strip 352 are adapted to the lower marbles, the hand-held handle 353 is rotated, so that the shaft core 314 drives the driving block 315 to rotate. The driving block 315 drives the limiting block 220 to rotate and move away from the limiting rod 250, so that the limiting module 200 can be changed to a free state. The outer shell 100 is pulled, so that the lock ring 130 moves relative to the outer shell 100, and then the unlocking action is completed.

[0045] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special instructions and limitations.
