DETAILED DESCRIPTION

[0035] In order to facilitate the understanding of those skilled in the art, the present utility model patent is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation mode are not limitations of the present utility model patent. The present utility model patent is described in detail below in conjunction with the drawings.

[0036] like Figure 1-8 As shown, the embodiment of the utility model provides a smart packaging box, which can perform signal recognition through the driving component 220, thereby driving the pulling device 213 to pull the bracket 210, so that the locking member 211 and the docking member 111 are separated from each other, and the packaging box can be opened. In the present technical solution, an unconventional password is used to identify the opening signal. Therefore, the encryption and anti-counterfeiting properties are relatively strong. At the same time, the pulling device 213 is used to pull the bracket 210 to separate the locking member 211 and the docking member 111. It is relatively reliable in mechanical structure, avoids the need to set a linkage device on the outside of the packaging box to open the lock by manual operation, and can improve the reliability of the packaging box after locking.

[0037] like Figure 1-8As shown, the embodiment of the utility model provides a smart packaging box, including a box body 100 provided with a accommodating cavity 101 and a cover body 110 rotatably connected to the box body 100 at one side edge for closing or opening the accommodating cavity 101, and a locking device 200 for locking the cover body 110 in a closed state is also provided in the accommodating cavity 101, and the locking device 200 includes: a bracket 210, a first elastic member 212, a pulling device 213 and a driving assembly 220, wherein the bracket 210 is slidably connected to the accommodating cavity 101 along a predetermined direction, and a locking member 211 is formed thereon, and a docking member 111 corresponding to the locking member 211 is provided on the cover body; one end of the first elastic member 212 abuts on the bracket 210, and the other end abuts on the stopper 102 formed in the accommodating cavity 101, so as to provide elastic support to the bracket 210, so that the locking member 211 and the docking member 1 11 are mutually engaged in a locked state; one end of the pulling device 213 is fixed in the accommodating cavity 101, and the other end is connected to the bracket 210, so as to generate an elastic pulling force to pull the bracket 210 to slide along a predetermined direction, so that the locking member 211 and the docking member 111 are separated in the locked state; the driving component 220 is electrically connected to the pulling device 213, so as to drive the pulling device 213 to generate an elastic pulling force to pull the bracket 210 along a predetermined direction, and the driving component 220 includes a power supply component 221 (not shown in the figure) electrically connected to each other, a signal receiving device and a control mainboard 223, the signal receiving device sends the received signal to the control mainboard 223, the control mainboard 223 compares the built-in preset signal with the received signal and determines whether it matches, and decides whether to drive the pulling device 213 to pull the bracket 210 according to the matching situation.

[0038] In the process of locking the packaging box, after the cover body 110 is flipped along the pivot to cover the accommodating cavity 101, the docking piece 111 and the locking piece 211 located on the cover body 110 are engaged with each other to lock the cover body 110 and keep it in the covered state. In the present embodiment, the docking piece 111 is configured as a plate formed on the cover body 110, and a card slot is provided on the plate. The locking piece 211 is a card block provided on the frame and connected in the card slot. By connecting the card block in the card slot, and at the same time, under the elastic force of the first elastic piece 212, the card block can be clamped in the card slot, so that the cover body and the box body 100 are locked to each other and kept in the locked state.

[0039] During the process of opening the packaging box, the security signal is sent to the signal recognition device 222, and the signal recognition device 222 recognizes it and transmits it to the control mainboard 223. The control mainboard 223 compares the received signal with the internal preset signal. When the received signal matches the preset signal, a driving signal is sent out, so that the power supply component 221 (not shown in the figure) provides driving power to the pulling device 213, so that the pulling device 213 generates elastic tension and then pulls the bracket 210, so that the bracket 210 can overcome the elastic force of the first elastic member 212, and the card block moves in a direction away from the card slot, and then disengages from the card slot, so that the locking member 211 and the docking member 111 are separated from each other, thereby unlocking the cover body 110 and the box body 100. Since the elastic tension generated by the pulling device 213 pulls the bracket 210, the movement of the bracket 210 can be relatively stable during the pulling process of the bracket 210, and the elastic tension can also make the bracket 210 have a certain elastic buffer during the pulling process.

[0040] During the process of unlocking and opening the locked packaging box, the signal recognition device 222 recognizes the user's input signal and then sends it to the control mainboard 223. The control mainboard 223 compares the received signal with the internal preset signal, and determines whether to send a driving signal based on the mutual coordination, so that the pulling device 213 pulls the bracket 210 through elastic tension. Through the method of this technical solution, a completely different unlocking method from the original technical solution is adopted, which makes the process of unlocking the cover body 110 more stable and reliable, and can greatly improve the confidentiality and anti-counterfeiting capabilities of the packaging box. Since the unlocking action is realized inside the packaging box, there is no component on the outside of the packaging box to operate the lock. Therefore, the reliability of the packaging box after locking can be improved.

[0041] In this embodiment, the signal receiving device is at least one of a password encryptor, a fingerprint encryptor, a face recognizer, an NFC password device, and a Bluetooth recognizer, so that it can receive and identify the password signal, fingerprint signal, face facial signal, Bluetooth signal, and NFC signal used for transmission, and send the identified signal to the control motherboard 223, which will identify the built-in pre-stored signal and determine whether to issue a driving signal based on the matching situation.

[0042] like Figure 4-8As shown, the pulling device 213 is a metal wire made of memory metal, and both ends of the pulling device 213 are electrically connected to the control mainboard 223. When the signal received by the signal receiving device matches the preset signal built into the control mainboard 223, the control mainboard 223 supplies power to the pulling device 213 to heat the pulling device 213 and achieve elastic contraction, thereby pulling the bracket 210 to move in a predetermined direction. By making the pulling device 213 used to pull the bracket 210 with memory metal, the memory metal heats up and produces elastic deformation after the power is supplied, so that the elastic force generated can pull the bracket 210, so that the bracket 210 will overcome the elastic force of the first elastic member 212 and move in a predetermined direction, and separate the locking member 211 from the docking member 111, thereby completing the unlocking action. It can be imagined that after the driving device cuts off the power supply to the pulling device 213, the temperature of the memory metal will decrease, thereby cooling to the memory temperature, so that the memory metal is easy to generate At this time, the elastic force of the pulling device 213 gradually decreases, so that under the action of the first elastic member 212, the bracket 210 can be slowly retracted, and the slow retraction speed will not cause a large impact on the bracket 210 during the retraction process, thereby ensuring the stability and reliability of the bracket 210 during the retraction and locking with the docking member 111, and as the memory metal is straightened and deformed, the locking member 211 and the docking member 111 can be mutually engaged through the action of the first elastic member 212, thereby completing the mutual locking of the cover body 110 and the box body 100. In this embodiment, the first elastic member 212 is a spring as an example.

[0043] By setting the memory metal as the pulling device 213 to pull the bracket 210, the overall structure of the lock can be reduced, avoiding the high failure rate and mutual jamming caused by the more complex mechanical structure, making the locking and opening of the packaging box more convenient and quicker. At the same time, the memory metal has strong and reliable elastic deformation and plastic deformation capabilities, and can reliably pull the bracket 210 to separate the cover body 110 and the box body 100 from each other. At the same time, after power failure, it can be quickly stretched to produce plastic deformation, so that the bracket 210 can be pushed under the action of the first elastic member 212, so that the locking member 211 and the docking member 111 are engaged with each other, and the box body 100 and the cover body 110 are locked to each other.

[0044] In order to limit the maximum travel of the bracket 210 and trigger the control main board 223 to send a stop signal to cut off the power supply to the pulling device 213, a limit switch 224 is also provided on the driving component 220. Figure 4-8As shown, the limit switch 224 is fixedly installed in the accommodating cavity 101 and is located on the moving track of the bracket 210 being pulled, and the limit switch 224 is electrically connected to the control mainboard 223 . When the pulling device 213 is driven by the control mainboard 223 to undergo differential elastic deformation and recovery, the bracket 210 is pulled, so that the bracket 210 drives the locking member 211 away from the docking member 111, thereby unlocking the cover body 110 and the box body 100 from each other. When the bracket 210 is pulled and moves to the position of the limit switch 224, the bracket 210 and the limit switch 224 contact each other and trigger the limit switch 224, so that the limit switch 224 sends a trigger signal to the control mainboard 223, and the control mainboard 223 cuts off the power supply to the pulling device 213, so that the temperature of the pulling device 213 made of memory metal stops rising and gradually decreases to below the memory temperature, so that it can be straightened and plastically deformed under the elastic force of the first elastic member 212, so that the bracket 210 can move toward the docking member 111, which can facilitate the box body 100 to be locked after the cover is closed.

[0045] When the bracket 210 is pulled and the locking member 211 and the docking member 111 are separated from each other, the cover 110 is unlocked. In order to prevent the locking member 211 and the docking member 111 from being stuck to each other, and the pulling device 213 from continuously pulling the bracket 210, thereby exceeding the limit pulling force of the pulling device 213 and causing damage to the pulling device 213, in this embodiment, Figure 7-8 As shown, a slide groove 214 extending along the sliding direction of the bracket 210 is provided on the bracket 210; a movable block 215 and a second elastic member 216 are also provided on the bracket 210, wherein the movable block 215 is slidably connected in the slide groove 214 along the length direction of the slide groove 214, the locking member 211 is formed on the movable block 215, and the second elastic member 216 is arranged in the slide groove 214 and is located at one end of the slide groove 214 away from the pulling device 213, and the two ends of the second elastic member 216 are respectively abutted against the movable block 215 and the inner wall of the slide groove 214.

[0046] Meanwhile, the elastic coefficient of the second elastic member 216 is greater than the elastic coefficient of the first elastic member 212 , and the maximum pulling force of the pulling device 213 is greater than the elastic force of the second elastic member 216 .

[0047] During the process of the pulling device 213 pulling the bracket 210, since the elastic coefficient of the second elastic member 216 is greater than the elastic coefficient of the first elastic member 212, the movable block 215 and the locking member 211 can maintain a stable state during the pulling process, so that they can move together with the bracket 210 to separate the locking member 211 from the docking member 111. During the process of pulling the bracket 210 to unlock the cover body 110 and the box body 100, when the locking member 211 and the docking member 111 are stuck to each other, the pulling device 213 generates an elastic force to pull the bracket 210. At this time, the bracket 210 will overcome the elastic force of the first elastic member 212 and move, and the movable block 215 is stuck in a fixed position. After the pulling force of the pulling device 213 gradually increases and exceeds the elastic force of the second elastic member 216, the second elastic member 216 can be pressed against each other. The member 216 is compressed, so that the bracket 210 can be pulled, and the bracket 210 can smoothly resist the limit switch 224, so that the control main board 223 stops providing power to the pulling device 213. Through the above structure, it is possible to avoid that the pulling device 213 is continuously pulled during the process in which the locking member 211 and the docking member 111 are stuck to each other, causing damage to the pulling device 213, the bracket 210, the locking member 211 or the docking member 111, thereby improving the safety performance and insurance capacity of the packaging box.

[0048] In order to install the locking device 200, Figure 3-6 As shown, an installation bin 120 is provided inside the accommodating cavity 101, the locking device 200 is installed inside the installation bin 120, and a cover plate 121 for closing the installation bin 120 is also provided on the installation bin 120, and a hole 123 for the docking piece 111 to pass through and lock with the locking piece 211 is opened on the cover plate 121.

[0049] By arranging the locking device 200 in the installation bin 120, the locking device 200 and the accommodating cavity 101 can be isolated from each other, so that the objects placed in the accommodating cavity 101 and the locking device 200 will not interfere with each other, thereby ensuring the reliability of locking and opening and closing.

[0050] In this embodiment, after the cover 110 is unlocked, the cover 110 can be automatically opened to facilitate the user's operation, and when the cover 110 is closed, the cover 110 can have a certain buffer force during the process of pressing down to close the cover, so that the docking member 111 will not be in hard contact with the locking member 211, such as Figure 3-4As shown, a buffer structure is also provided in the installation bin for providing elastic buffer force when the cover body 110 closes the accommodating cavity 101, and the buffer structure includes a mounting hole 124 formed on the side wall of the installation bin 120; a third elastic member 125 placed on the bottom of the mounting hole 124; a buffer rod 126 slidably connected to the mounting hole 124 along a straight line direction of the mounting hole 124 and abutting against the third elastic member 125 at the lower end, and a flange 127 is provided in the middle section of the buffer rod 126; a through hole 128 is opened on the cover plate 121 for the upper end of the buffer rod 126 to extend, and the inner diameter of the through hole 128 is smaller than the diameter of the flange 127.

[0051] The buffer rod 126 is extended along the through hole 128 under the elastic force of the third elastic member 125, so that the upper end of the buffer rod 126 is located on the upper side of the cover plate 121. In the process of closing the cover body 110, the cover body 110 is in contact with the upper end of the buffer rod 126 in advance, so that the cover body 110 can be provided with elastic buffering under the action of the third elastic member 125, so as to avoid that the docking member 111 is quickly and rigidly engaged with the locking member 211 in the process of closing the cover body 110, thereby avoiding damage to the docking member 111 or the locking member 211 due to the large impact force. At the same time, after the locking member 211 is separated from the docking member 111, the cover body 110 can be quickly tilted upward under the push of the buffer rod 126, so as to be convenient for opening the cover body 110.

[0052] In a smart packaging box provided by the present embodiment, the pulling device 213 composed of memory metal is heated up by the driving component 220 to generate elastic force, and then the bracket 210 is pulled, so that the docking member 111 and the locking member 211 are separated from each other, and the cover body 110 can be in a contact locking state. In the contact locking state, the bracket 210 is pulled and moved slowly by the elastic force, so that the bracket 210 can move more smoothly during the movement process, and after the power supply of the pulling device 213 is cut off, the elastic force of the pulling device 213 can be gradually reduced, so that the bracket 210 can be slowly retracted, avoiding rapid retraction under the action of the first elastic member 212, and damaging the internal structure of the bracket 210 and the locking device 200; at the same time, through the setting of the driving device, the previous unlocking method of inputting a password can be changed, and the confidentiality and security performance are higher.
