Lock holes corresponding to the side lock 7 are provided at corresponding positions on the left side panel 14 and the right side panel 15. The function of the side lock 7 is to prevent the front side panel 12 and the rear side panel 13 from freely falling inward again when the four side panels are unfolded, so as to form a stable box structure. The side lock 7 and the corresponding lock hole are the fifth lock member and the sixth lock member respectively.

[0075] In this embodiment, the upper edge surface j of the protrusion 122 can be further set to be an arc surface, the center of which coincides with the rotation axis of the front side plate 12, and the upper edge surface k of the corresponding recess h of the left side plate 14 is also an arc surface, which fits tightly with the upper edge surface of the protrusion 122.

[0076] In the aforementioned embodiment, the power module includes a rechargeable battery and a charge-discharge management unit connected to the rechargeable battery, the rechargeable battery is arranged at the bottom of the base, the charge-discharge management unit is connected to a charging interface arranged on the side wall of the base, or connected to a wireless charging unit, and the induction coil of the wireless charging unit is arranged on the side wall or the bottom of the base. The wireless charging unit facilitates charging when the box is placed on a dedicated shelf or a flat panel, meeting the need for charging at any time.

[0077] The interactive module may also include a display screen or indicator, such as a liquid crystal display, a segment code screen, a digital tube, an electronic ink screen, an LED, or other device with a display or indication function, which may be used to display express box information, waybill information, or send an indication signal, etc.

[0078] The communication module can be connected to the Internet or a dedicated management network, and has communication functions such as 4G, 5G, or has WIFI, NFC or Bluetooth connection functions, etc.

[0079] The present invention is an intelligent packaging box. Based on the above embodiments, the functions and principles of the present invention are as follows.

[0080] Folding function: The cover plate and the buffer device of the present invention are both independent components. After the cover plate is removed (opened), the airbags corresponding to the six surfaces of the buffer device are folded up in a conventional manner and placed in the storage chamber of the base. There are two ways to reduce the volume of the airbag. One is to use a special vacuum pump to connect the charging and discharging ports to extract the gas in the airbag to reduce the volume of the airbag; the other is to fold the airbag and directly press it to discharge the gas in the airbag through the charging and discharging ports to reduce the volume of the airbag to adapt to the volume of the storage chamber.

[0081] Flip the front and rear side panels inward to the top of the storage room, and then flip the left and right side panels inward to the top of the storage room (also the top of the front and rear side panels). At this time, the second locks on the left and right side panels are located at the top of the whole. Place the cover plate on the top of the left and right side panels. At this time, the first lock on the cover plate is aligned with the second lock on the left and right side panels. Move the slider on the first lock so that the hook extends out and hooks the hanging rod in the second lock to complete the overall folding. The cover plate and the base are made to have the same projection size. After folding, the present invention is a rectangular parallelepiped structure as a whole, which is convenient for stacking, storage and transportation.

[0082] In the above embodiment, the left and right side panels do not overlap after being tilted inwards, and the front and rear side panels do not overlap after being tilted inwards. In actual applications, the left and right side panels may overlap in some areas after being tilted inwards (such as Fig.23 ), or the front and rear side panels will overlap partially after being tilted inwards, or the front and rear side panels, left and right side panels will be folded (as shown in Fig.24 As shown). The front and rear side panels overlapped inwards and backwards without affecting the overall folding, and only the corresponding sides of the base need to be appropriately raised. However, the overlap of the left and right side panels will affect the connection between the cover plate and the left and right side panels, that is, affect the overall folding. In this case, the hook corresponding to the left side panel in the first locking member needs to be lengthened so that it can hook the hanging rod on the left side panel.

[0083] Expand function: The present invention is a rectangular parallelepiped structure after being unfolded. After the first lock is moved to unlock the first lock and the second lock, the cover plate can be removed, and the four side panels are unfolded in sequence to a vertical state, and the side locks are locked, so that the four side panels and the base form a stable uncovered box body. The airbags corresponding to the front, rear, left and right side panels and the upper cover of the buffer device are unfolded from the storage chamber (the airbags corresponding to the base can be bonded by Velcro), and the items are placed in the enclosed space of the four side airbags and the upper cover airbag is covered thereon, and then allowed to naturally inhale and expand or inflate through the inflation and deflation ports to make it expand rapidly and fill the gaps between the four side panels and the items, and then the cover plate is buckled onto the four side panels. During the buckling process, the third lock and the fourth lock automatically complete the locking, and the box body cannot be opened unless through the control system.

[0084] The locking and unlocking process of the third locking member and the fourth locking member is as follows: Fig.10 As shown: a state where the cover and the side panel are separated is as follows Figure 10-2 As shown, the lock tongue 512 extends out of the housing 511, and the cover plate can be buckled against the side plate to close the express box. The specific process is: when the cover plate is buckled against the side plate, the slope of the lock tongue 512 is squeezed by the inner side of the edge of the side plate, and the lock tongue 512 shrinks into the housing 511 (the edge of 512 is aligned with the outer edge of the housing 511, and the limit hole 518 does not reach the bottom of the limit rod 5141). Figure 10-2 As shown. When the cover continues to be pressed down until the lock tongue 512 is aligned with the lock hole 52 on the side panel, the lock tongue is pushed into the lock hole by the first return spring 517 and returns to the state shown in 10-1. The cover is then locked with the side panel and the cover cannot be removed at will. To unlock, authorization must be obtained through the control system, which activates the electromagnet 513 to drive the lock tongue 512 into the shell 511, so that the limiting hole 518 moves to the bottom of the limiting rod 5141. The second return spring 5145 drives the limiting rod 5141 to move downward and insert into the limiting hole 518, while driving the push rod 5142 to extend out of the shell 511. The lock tongue 512 no longer pops out. Figure 10-3 As shown, the operator can lift the cover plate, separate it from the side plate, and open the packaging box.

[0085] Before buckling the cover plate onto the side plate again, the operator needs to press the push rod 5142 (compress the third return spring 5147) to pull the limit rod 5141 out of the limit hole 518, and the lock tongue is pushed out of the housing 511 by the first return spring 517 to return to the position. Figure 10-1 Status shown.

[0086] If the corresponding positions of the push rod 5142 and the slide rod 5143 are set as follows Fig.26 As shown in the oblique notch 5148, the push rod 5142 does not need to be provided with a third return spring 5147 ( Fig. 9 , 10 As shown in FIG. 5 ), the push rod 5142 and the limiting rod 5141 can drive each other.

[0087] In order to ensure the coordination between the sliding rod 5143 and the pushing rod 5142, the limiting rod 5141 should not be able to rotate. The above-mentioned embodiment limits the rotation of the limiting rod 5141 by setting a matching key and keyway 5146. In actual applications, the cross-section of the limiting rod 5142 may also be set to a square, semicircular or other special shape, and the cross-section of the inner tube of the corresponding sleeve seat 5144 is also a corresponding shape, thereby achieving the effect of limiting the rotation of the limiting rod.

[0088] In practical applications, the number of the first locking member, the second locking member, the third locking member, the fourth locking member, the side locks, etc. can be increased or decreased as needed and is not limited to the number in the aforementioned embodiments.

[0089] Based on the structure and functions recorded in the technical solution of the present invention, those skilled in the art can realize functions such as remote monitoring and wireless control of the express box.

[0090] The present invention can be used as an independent storage box for home or car use, and can also be used as an express box for express logistics. Example 5
