As shown in fig. 1 to 9, the present invention provides an intelligent express delivery cabinet with an adjustable storage space, which includes a cabinet body 1000, wherein the cabinet body 1000 is provided with a plurality of installation cavities 1100, any installation cavity 1100 is provided with a placement unit 2000 therein, and the placement unit 2000 is used for storing express items.

The placing unit 2000 includes a housing 2100, a partition 2200, and a cabinet door assembly 2300.

Wherein the housing 2100 is fixedly installed in the installation cavity 1100. Preferably, housing 2100 is compatible with mounting cavity 1100. The housing 2100 has a placement cavity 2110 with a front opening for the placement cavity 2110.

The partition 2200 slides in the placing chamber 2110 to divide the placing chamber 2110 into a first chamber 2111 and a second chamber 2112, and the partition 2200 may reciprocate in a straight line left and right in the placing chamber 2110 to change the sizes of the first chamber 2111 and the second chamber 2112 by the driving device 2400. In use, the position of the partition 2200 can be changed according to the size of the express item to be placed, so that one or two express items can be placed in one placing cavity 2110. Specifically, when the express mail is large and needs to occupy the whole placing cavity 2110, the driving device 2400 drives the partition plate 2200 to move to the leftmost end or the rightmost end; when one express article does not occupy the whole placing cavity 2110 enough, the driving device 2400 drives the partition plate 2200 to a proper position in the middle of the placing cavity 2110, so as to divide the placing cavity 2110 into the first cavity 2111 and the second cavity 2112, and thus, a proper express article can be placed in the first cavity 2111 and the second cavity 2112, and the purpose of fully utilizing the placing space of the express cabinet is achieved.

The cabinet door assembly 2300 is used to open or close the placement chamber 2110, and the cabinet door assembly 2300 may separately open or close the first and second chambers 2111 and 2112. Specifically, when the express item in the first cavity 2111 needs to be taken out or placed into the first cavity 2111, the cabinet door assembly 2300 may only open the first cavity 2111 and keep the second cavity 2112 closed; likewise, when it is desired to remove a quick-release item from the second cavity 2112 or place a quick-release item into the second cavity 2112, the door assembly 2300 may simply open the second cavity 2112 while maintaining the first cavity 2111 closed.

In one embodiment, the door assembly 2300 includes a door body 2310, a first locking structure 2320, a baffle 2330, and a second locking structure 2340.

The door body 2310 is provided at an opening of the placing chamber 2110. The number of the first locking structures 2320 is two, the two first locking structures 2320 are respectively disposed at the left and right sides of the door body 2310, and the first locking structures 2320 are used for locking the door body 2310. Specifically, one end or both ends of the door body 2310 are fixedly connected to the cabinet 1000. When both ends of the door body 2310 are fixedly connected with the cabinet 1000 through the first locking structure 2320, the door body 2310 can seal the placing cavity 2110. When only one first locking structure 2320 locks the door body 2310, the door body 2310 is hinged to the cabinet 1000 through the first locking structure 2320. Specifically, when only the first locking structure 2320 located at the left side of the door body 2310 locks the door body 2310, the right side of the door body 2310 can rotate around the left side thereof; similarly, when only the first locking structure 2320 on the right side of the door body 2310 locks the door body 2310, the left side of the door body 2310 can rotate around the right side thereof; when the two first locking structures 2320 lock the door body 2310, the door body 2310 is fixedly connected with the housing 2100 to close the placing cavity 2110.

A mounting groove 2311 is formed at one side of the door body 2310 facing the housing 2100, and a rear side of the mounting groove 2311 is open. A plurality of blocking plates 2330 are sequentially arranged in parallel in the installation groove 2311 and detachably coupled to the door body 2310. The upper and lower ends of any one of the blocking plates 2330 are provided with second locking structures 2340 for locking the blocking plate 2330. Specifically, when the second locking structure 2340 locks the blocking plate 2330, the blocking plate 2330 is fixedly connected to the cabinet 1000. In use, when the first cavity 2111 needs to be opened, the first locking structure 2320 corresponding to the first cavity 2111 unlocks the door body 2310, meanwhile, the second locking structure 2340 for locking the baffle 2330 corresponding to the first cavity 2111 unlocks the baffles 2330, and the second locking structure 2340 for locking the baffle 2330 corresponding to the second cavity 2112 continues to lock the baffles 2330. At this time, the door body 2310 is rotated, and the baffle 2330 corresponding to the second cavity 2112 is fixedly connected to the cabinet 1000 by the second locking structure 2340, so as to continuously seal the second cavity 2112. The blocking plate 2330 corresponding to the first chamber 2111 may rotate together with the door body 2310 due to the lack of locking of the second locking structure 2340, thereby opening the first chamber 2111.

To facilitate a better description of the operation of the door assembly 2300, the first chamber 2111 is defined as the chamber on the left side of the partition 2200, and the second chamber 2112 is defined as the chamber on the right side of the partition 2200.

When the first cavity 2111 needs to be opened, the first locking structure 2320 located at the left side of the door body 2310 unlocks the door body 2310, so that the left side of the door body 2310 can rotate around the right side of the door body 2310, and meanwhile, the second locking structure 2340 for locking the baffles 2330 located at the left side of the partition 2200 (i.e. the baffles 2330 corresponding to the first cavity 2111) unlocks the baffles 2330, so that the baffles 2330 can move along with the door body 2310, so that the first cavity 2111 is opened; while the second latching structure 2340 for latching the baffles 2330 located on the right side of the partition 2200 (i.e., the baffles 2330 corresponding to the second chamber 2112) continues to remain latched to the baffles 2330 so that the baffles 2330 enclose the second chamber 2112. Rotating the door body 2310, the door body 2310 rotates together due to the absence of the locking of the second locking structure 2340 of the blocking plate 2330 located at the left side of the partition 2200, thereby opening the first chamber 2111; the blocking plate 2330 on the right side of the partition 2200 cannot rotate with the door 2310 by the second locking structure 2340, so that the second chamber 2112 is kept closed.

When the second cavity 2112 needs to be opened, the first locking structure 2320 located at the right side of the door body 2310 unlocks the door body 2310, so that the right side of the door body 2310 can rotate around the left side of the door body 2310, and meanwhile, the second locking structure 2340 for locking the baffles 2330 located at the right side of the partition 2200 (i.e. the baffles 2330 corresponding to the second cavity 2112) unlocks the baffles 2330, so that the baffles 2330 can move along with the door body 2310, so that the second cavity 2112 is opened; while the second latching structure 2340 for latching the baffles 2330 located at the left side of the partition 2200 (i.e., the baffles 2330 corresponding to the second chamber 2112) continues to maintain the latching of the baffles 2330 such that the baffles 2330 enclose the first chamber 2111. Rotating the door body 2310, the second chamber 2112 is opened as the door body 2310 is rotated due to the absence of the locking of the second locking structure 2340 by the blocking plate 2330 located at the right side of the partition 2200; the baffle 2330 on the left side of the partition 2200 cannot rotate with the door 2310 under the action of the second locking structure 2340, so that the first cavity 2111 is kept closed.

The cabinet door assembly 2300 has a simple structure, and can independently close and open the first and second cavities 2111 and 2112, and also can be changed according to the size change of the first and second cavities 2111 and 2112.

In one embodiment, the cabinet door assembly 2300 further includes a third permanent magnet 2350 and a fourth permanent magnet 2360.

A third permanent magnet 2350 is fixedly mounted on the front side of any one of the blocking plates 2330. The fourth permanent magnet 2360 is fixedly embedded in the door body 2310, and the magnetism of the side of the fourth permanent magnet 2360 opposite to the third permanent magnet 2350 is opposite.

When the second locking structure 2340 is unlocked from the baffle 2330, the baffle 2330 can rotate along with the door body 2310 under the magnetic force of the fourth permanent magnet 2360 and the third permanent magnet 2350; when the second locking structure 2340 keeps locking the blocking plate 2330, the blocking plate 2330 overcomes the magnetic force of the third permanent magnet 2350 and the fourth permanent magnet 2360 under the action of the second locking structure 2340, and cannot rotate together with the door body 2310.

With the structure, the door body 2310 is simple in structure, and the door body 2310 and the baffle 2330 can be connected and separated conveniently.

In one embodiment, the number of fourth permanent magnets 2360 is equal to and one-to-one correspondence with the number of third permanent magnets 2350.

When the baffle plate is used, a whole block of the fourth permanent magnet 2360 is not needed to be arranged to suck all the baffle plates 2330, so that the using amount of the fourth permanent magnet 2360 is reduced, and the cost is saved.

In one embodiment, the first locking structure 2320 includes a first locking pin 2321, a first permanent magnet 2322, a first electromagnet 2323, and a first locking aperture 2324.

The upper and lower sides of the door body 2310 are provided with first mounting holes 2312. The number of the first locking pins 2321 is two, and the two first locking pins 2321 are slidably disposed in the two first mounting holes 2312, respectively. The number of the first permanent magnets 2322 is two, and the two first permanent magnets 2322 are respectively installed at opposite ends of the two first locking pins 2321 and are fixedly connected to the first locking pins 2321. The number of the first electromagnets 2323 is two, and the two first electromagnets 2323 are respectively disposed at one side opposite to the two first permanent magnets 2322 and fixedly connected to the housing 2100. The first locking holes 2324 are opened on the cabinet 1000 and correspond to the locking pins one to one.

When the door body 2310 needs to be locked by the first locking structure 2320, the first electromagnet 2323 is electrified, the magnetism of the opposite side of the first electromagnet 2323 and the first permanent magnet 2322 is the same, so that a repulsive force is generated, and under the action of the repulsive force, the first locking pin 2321 is inserted into the first locking hole 2324, so that the door body 2310 is locked; when the first locking structure 2320 is required to unlock the door body 2310, the first electromagnet 2323 is energized to make the opposite sides of the first electromagnet and the first permanent magnet 2322 opposite in magnetism, thereby generating an attraction force, and the first locking pin 2321 is pulled out from the first locking hole 2324 by the attraction force, thereby unlocking.

The first locking structure 2320 of this structure is simple in structure.

In an embodiment, the first locking structure 2320 further includes two first springs 2325, the two first springs 2325 are respectively sleeved on the two first locking pins 2321, and in a natural state, the two first springs 2325 have a tendency to make the two first locking pins 2321 approach each other.

When the door body 2310 needs to be locked by the first locking structure 2320, the first electromagnet 2323 is electrified, the opposite side of the first electromagnet 2323 and the first permanent magnet 2322 has the same magnetism, so that a repulsive force is generated, and under the action of the repulsive force, the first locking pin 2321 overcomes the elastic force of the first spring 2325 and is inserted into the first locking hole 2324, so that the door body 2310 is locked; when the first locking structure 2320 is required to unlock the door body 2310, the first electromagnet 2323 is de-energized, and the first locking pin 2321 is pulled out of the first locking hole 2324 by the elastic force of the first spring 2325, thereby unlocking.

The first locking structure 2320 of this structure is simple in structure, and the current direction of the first electromagnet 2323 does not need to be changed.

In one embodiment, the second locking structure 2340 includes a second locking pin 2341, a second permanent magnet 2342, a second electromagnet 2343, and a second locking hole 2344.

The cabinet body 1000 is provided with a second mounting hole 1200, and the second locking pin 2341 is slidably mounted in the second mounting hole 1200. The second permanent magnet 2342 is mounted on an end of the second locking pin 2341 away from the blocking plate 2330 and is fixedly connected to the second locking pin 2341. The second electromagnet 2343 is installed at one end of the second permanent magnet 2342 far from the second locking pin 2341 and is fixedly connected with the cabinet 1000. A second locking hole 2344 is opened on the blocking plate 2330 and corresponds to the second locking pin 2341.

In use, when the second locking structure 2340 is required to lock the baffle 2330, the second electromagnet 2343 is energized and makes the side of the second electromagnet 2343 opposite to the second permanent magnet 2342 magnetic identically so as to generate a repulsive force, under the action of which the second locking pin 2341 is inserted into the second locking hole 2344 so as to lock the baffle 2330; when the second locking structure 2340 is required to unlock the shutter 2330, the second electromagnet 2343 is energized and the second electromagnet 2343 is magnetically opposed to the opposite side of the second permanent magnet 2342 to generate an attraction force, and under this attraction force, the second locking pin 2341 is pulled out of the second locking hole 2344 to unlock the shutter 2330. Preferably, the locking device further comprises a second spring, the second spring is sleeved on the second locking pin 2341, and in a natural state, the second spring has a tendency of enabling the second locking pin 2341 to move in a direction away from the second locking hole 2344.

In one embodiment, a position sensor is further included, which is disposed on the cabinet 1000 and is used to confirm the position of the partition 2200 within the placing cavity 2110. In use, the position of the partition 2200 can be determined based on the information transmitted from the position sensor, such that when the first chamber 2111 or the second wall is opened, which of the shutters 2330 should be unlocked and which of the shutters 2330 should continue to remain locked.

In one embodiment, the drive device 2400 includes a lead screw 2410 and a motor 2420.

The number of the lead screws 2410 is two, and the two lead screws 2410 are respectively rotatably disposed on the upper and lower sides of the housing 2100 and are in threaded connection with the partition plate 2200. The power output shaft of the motor 2420 is in transmission connection with the power input end of the lead screw 2410. Specifically, the power input end of the screw rod is provided with a driven wire wheel, the power output shaft of the motor 2420 is provided with a driving wire wheel, and the driven wire wheel is in transmission connection with the driving wire wheel through a transmission line.

In use, the motor 2420 is controlled to rotate forward and backward, so that the lead screw 2410 drives the partition plate 2200 to do reciprocating linear motion.

The driving device 2400 with this structure has a simple structure.
