Description

Technical Field

[0001] The present invention relates to the technical field of article storage boxes, and in particular to an article delivery box. Background Art

[0002] Some food delivery boxes are cubes with smooth surfaces, so they can be easily stacked. During transportation, some road conditions are uneven, and the vehicle will be bumpy, causing the food delivery boxes stacked on top to fall, which is easy to damage the food. For this reason, a technician has provided a logistics transfer box, such as patent document CN209441875U, in which the top wall of the logistics transfer box is provided with a raised stacking piece, and the bottom wall is provided with a stacking groove corresponding to the stacking piece. When stacking multiple logistics transfer boxes, the stacking pieces of the logistics transfer boxes on the lower layer are inserted into the stacking groove of the logistics transfer boxes on the upper layer, so that the logistics transfer boxes stacked on top can be prevented from sliding and falling due to bumpy road conditions. However, bumpy road conditions may cause the upper box to be lifted up, and then the stacking pieces of the lower box will be separated from the stacking groove of the upper box, causing the upper box to fall. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an article delivery box, which is convenient for stacking and can prevent the upper article delivery box from falling during transportation.

[0004] In order to solve the above technical problems, an article delivery box of the present invention includes a sensing element and a locking element controlled by the sensing element, specifically:

[0005] If the sensing element senses that the item delivery box is stacked on top of another item delivery box, the locking element is locked to lock the two item delivery boxes together; and / or

[0006] If the sensing element senses that the article delivery box and a similar article delivery box are no longer stacked one above the other, the locking element is unlocked so that the two article delivery boxes are no longer locked together.

[0007] Furthermore, the locking element and the sensing element are both arranged on the bottom surface of the item delivery box or are both arranged on the top surface of the item delivery box.

[0008] Furthermore, the bottom and top surfaces of the item delivery box that are not provided with the locking element are provided with transverse blocking walls corresponding to the locking element, and the locking element is laterally extended to lock. When the two item delivery boxes are stacked up and locked as described above, the blocking wall of one item delivery box blocks the locking element of the other item delivery box to prevent the two item delivery boxes from being separated vertically.

[0009] Furthermore, when the two delivery boxes are stacked up and locked as described above, a vertical distance H is left between the blocking wall and the locking element to allow the locking element to move vertically without crossing the blocking wall. If the locking element moves vertically to a vertical distance from the blocking wall that is less than or equal to h, the sensing element senses that the delivery box is no longer stacked up with the same delivery box, and the locking element retracts, resets, and unlocks, wherein h is <H。

[0010] Furthermore, the article delivery box where the blocking wall is located has a transverse locking hole, and the locking piece of another article delivery box extends transversely into the locking hole to achieve locking, and the hole wall of the locking hole close to the other article delivery box serves as the blocking wall.

[0011] Furthermore, the locking element is an electromagnetic lock, and the sensing element is a switch for controlling the power on and off of the electromagnetic lock. Specifically: if the sensing element senses that the item delivery box is stacked up with a similar item delivery box, the electromagnetic lock is switched on and off to lock it; if the sensing element senses that the item delivery box is no longer stacked up with a similar item delivery box, the electromagnetic lock is switched on and off in the reverse direction to unlock it.

[0012] Furthermore, the sensing element is a micro switch provided on the top or bottom surface of the item delivery box, specifically:

[0013] If the article delivery box is stacked on top of another article delivery box of the same type, the micro switch is pressed by the article delivery box of the same type to achieve induction;

[0014] If the article delivery box is separated from another identical article delivery box stacked on top of it, the micro switch is no longer squeezed by the identical article delivery box and automatically resets to achieve induction.

[0015] Furthermore, a controller is included which is electrically connected between the sensing element and the locking element, and the sensing element controls the locking and / or unlocking of the locking element through the controller.

[0016] Furthermore, a first top surface positioning portion is provided on the top surface of the item delivery box, and a first bottom surface positioning portion corresponding to the first top surface positioning portion is provided on the bottom surface. When two such item delivery boxes are stacked up one above the other, the first top surface positioning portion of the lower item delivery box engages with the first bottom surface positioning portion of the upper item delivery box to achieve lateral positioning.

[0017] Further, the locking piece is arranged at the first top surface positioning portion or the first bottom surface positioning portion, and the blocking wall is arranged at the positioning portion where the locking piece is not arranged.

[0018] Furthermore, the positioning portion with the locking piece is a card block, and the positioning portion with the blocking wall is a card slot. The card block has a transverse accommodating slot, the locking piece is arranged in the accommodating slot, and the accommodating slot has a through hole for the locking piece to extend transversely.

[0019] Furthermore, the top surface of the item delivery box is provided with a second top surface positioning portion, and the bottom surface is provided with a second bottom surface positioning portion corresponding to the second top surface positioning portion. When two such item delivery boxes are stacked up and down, the second top surface positioning portion and the second bottom surface positioning portion engage to achieve lateral positioning.

[0020] The article delivery box includes a sensing element and a locking element controlled by the sensing element. If the sensing element senses that the article delivery box is stacked with a similar article delivery box, the locking element is locked to lock the two article delivery boxes together; if the sensing element senses that the article delivery box is no longer stacked with the similar article delivery box, the locking element is unlocked to lock the two article delivery boxes together. In this way, even if the road is bumpy, the multiple article delivery boxes stacked up and down will not separate, thereby effectively preventing the upper article delivery box from falling.

DETAILED DESCRIPTION

[0028] like Figure 1 As shown, a food delivery box (i.e., an article delivery box) is provided with a plurality of accommodating chambers 10 with placement openings. The food delivery box is provided with a corresponding closed door 1 for each accommodating chamber 10, and the left side of the closed door 1 is hinged to the cavity wall on the left side of the placement opening of the accommodating chamber 10. A lock 11 is provided on the right side of the closed door 1, and the cavity wall on the right side of the placement opening of the accommodating chamber 10 is provided as shown in FIG. Figure 2 The electromagnetic lock cylinder 12 shown. The food delivery box is provided with a controller, which is electrically connected to the electromagnetic lock cylinder 12. Figure 2 The uppermost closed door 1 on the right side of the image is in a state where the closed door 1 seals the placement opening, and the lock catch 11 extends into the electromagnetic lock core 12. The controller controls the electromagnetic lock core 12 to lock the lock catch 11, thereby locking the closed door 1.

[0029] Each accommodating cavity 10 and each electromagnetic lock core 12 are configured with a corresponding unique number. The controller includes a storage module, which stores the number of each accommodating cavity 10 and the number of the corresponding electromagnetic lock core 12, and also records the placement status of each accommodating cavity 10, which is divided into two situations: empty and occupied. The food delivery box is provided with a barcode scanner 9 electrically connected to the controller. Figure 1 The food packaging box 20 in the box contains food, and a QR code is attached to the outer surface of the box. If a store orders food, the delivery person takes out an empty food delivery box, and each accommodating cavity 10 of the delivery box does not store food. Figure 1The food packaging box 20 in the food packaging box 20. The delivery person aligns the QR code on the outer surface of the food packaging box 20 to be delivered with the code scanner 9. The code scanner 9 scans the QR code to obtain the information of the food packaging box 20, and sends the above information to the controller. After receiving the information of the food packaging box 20, the controller queries the placement status of each accommodating cavity 10 in the storage module, allocates an empty accommodating cavity 10 to the food packaging box 20, associates the information of the food packaging box 20 with the number of the allocated accommodating cavity 10, and stores the association relationship in the storage module, and then changes the placement status of the allocated accommodating cavity 10 from vacant to occupied. At the same time, the controller controls the electromagnetic lock core 12 corresponding to the allocated accommodating cavity 10 to unlock and thus bounce the closed door 1. The delivery person can put the current food packaging box 20 into the accommodating cavity 10, put the food packaging box 20, and then manually close the closed door 1 of the accommodating cavity 10, and the corresponding electromagnetic lock core 12 is locked again. The food delivery box is provided with a refrigeration module and a battery for powering the refrigeration module. The refrigeration module has multiple cold air output terminals, which correspond to multiple accommodating chambers 10 one by one. Each cold air output terminal is connected to the corresponding accommodating chamber 10 through an electrically controlled one-way valve. The electrically controlled one-way valve is electrically connected to the controller. After the electromagnetic lock cylinder 12 is re-locked, the controller starts the refrigeration module and turns on the electrically controlled one-way valve of the cold air output terminal corresponding to the allocated accommodating chamber 10, thereby refrigerating and preserving the food packaging box 20 placed in the accommodating chamber 10. Similarly, the delivery person puts each food packaging box 20 to be delivered into the food delivery box in turn.

[0030] Assume that there are a large number of food packaging boxes 20 to be delivered, and dozens of food delivery boxes are needed to store them. After storing all the food packaging boxes 20, the delivery person can load the food delivery boxes into the truck. Figure 3 As shown, the top surface of the food delivery box is provided with two card slots 2 as the first top surface positioning part and two strip card slots 5 as the second top surface positioning part. Figure 4As shown, the bottom surface of the food delivery box is provided with two blocks 3 as the first bottom surface positioning parts and two strip blocks 6 as the second bottom surface positioning parts. A delivery box placement board is provided on the bottom surface of the transport vehicle compartment, and a plurality of placement positions are provided on the upper surface of the delivery box placement board, and each placement position is provided with two positioning card slots corresponding to the two blocks 3 and two strip positioning slots corresponding to the two strip blocks 6. Handles 8 are provided on the left and right sides of the food delivery box. The deliveryman uses the handles 8 to lift a food delivery box onto the transport vehicle and aligns it with the placement position on the delivery box placement board so that the block 3 and the strip block 6 on the bottom surface of the food delivery box are respectively inserted into the positioning card slot and the strip positioning slot in the placement position. After placing the first food delivery box, the deliveryman lifts the second food delivery box and places it on the first food delivery box so that the block 3 and the strip block 6 on the bottom surface of the second food delivery box are respectively inserted into the card slot 2 and the strip card slot 5 on the top surface of the first food delivery box below. A transverse receiving groove is formed in the card block 3, and an electromagnetic lock 4 (i.e., a locking member) with a retractable locking rod is provided in the receiving groove. A through hole 31 is formed on the left groove wall of the receiving groove in the left card block 3 and on the right groove wall of the receiving groove in the right card block 3, through which the locking rod of the electromagnetic lock 4 can extend transversely. A transverse locking hole 41 is formed on the left groove wall of the left card slot 2 and on the right groove wall of the right card slot 2, which leads to the left wall of the food delivery box. A micro switch 42 ( Figure 4 ), which is connected between the power source (the power source refers to the above-mentioned battery and DC power source) and the electromagnetic lock 4 in the circuit. When the second food delivery box is stacked on the first food delivery box, the spring sheet of the micro switch 42 on the bottom surface of the second food delivery box is squeezed by the top surface of the food delivery box below, so that the electromagnetic lock 4 is energized, and the electromagnetic lock 4 will extend horizontally into the lock hole 41, thereby locking the card block 3 and the card slot 2 together. The deliveryman then places the third food delivery box on the second food delivery box, so that the card block 3 and the bar card block 6 on the bottom surface of the third food delivery box are respectively inserted into the card slot 2 and the bar card slot 5 on the top surface of the second food delivery box below, and then the spring sheet of the micro switch 42 on the bottom surface of the third food delivery box is squeezed by the top surface of the food delivery box below, so that the electromagnetic lock 4 is energized, so that the electromagnetic lock 4 extends into the lock hole 41, thereby locking the card block 3 and the card slot 2 together. By analogy, multiple food delivery boxes are stacked and placed in the transport vehicle. After stacking to the restricted height, the delivery person finds another placement position on the delivery box placement board that is adjacent to the placement position where the first food delivery box is placed, and stacks multiple food delivery boxes again on this placement position. After loading, the delivery person can start delivery. Because the electromagnetic lock 4 locks the card block 3 and the card slot 2 of the two stacked food delivery boxes together, the food delivery box located on the upper side will not be separated from the food delivery box located on the lower side due to bumpy road conditions during transportation, and the food delivery box located on the upper side will not be lifted up and dropped.

[0031] In this embodiment, the controller of the food delivery box is electrically connected to the electromagnetic lock 4, so that the working status of the electromagnetic lock 4, whether locked or unlocked, can be known, and the storage module thus records the working status of the electromagnetic lock 4 in real time.

[0032] The transport vehicle is provided with a wireless power supply induction module and a power supply device electrically connected to the wireless power supply induction module. The left and right side walls of the food delivery box are provided with wireless power supply induction modules 71 that match the wireless power supply induction module. Correspondingly, the food delivery box is provided with a DC power supply for receiving the electric energy taken by the wireless power supply induction module 71, which is electrically connected to the wireless power supply induction module 71 and the refrigeration module respectively. After the food delivery box is placed on the transport vehicle, its wireless power supply induction module 71 is connected to the wireless power supply induction module to draw power from the power supply device in the car. The controller electrically connects the battery and the DC power supply through a switching switch. In a state where power can be drawn through the wireless power supply induction module 71, the controller controls the switching switch to switch from battery power supply to DC power supply power supply.

[0033] like Figure 5 As shown, the diameter of the locking rod of the electromagnetic lock 4 is 5mm, and the vertical width of the lock hole 41 is 20mm, which is larger than the diameter of the locking rod. With the hole wall at the top of the lock hole 41 as a blocking wall, when the locking rod is inserted into the lock hole 41 and locked, a vertical distance H is left between the locking rod and the hole wall at the top of the lock hole 41, H=15mm, so that the locking rod can move vertically in the lock hole 41. When the food delivery boxes are stacked up and locked, the vertical displacement caused by the squeezing of the spring sheet of the micro switch 42 is 3mm, which is less than the maximum vertical distance H of the vertical movement of the locking rod in the lock hole 41. After being transported to the destination, since the locking rod can move vertically in the lock hole 41, when the electromagnetic lock 4 is not unlocked, the delivery person can lift the top food delivery box up a short distance. During this process, the bottom surface of the top food delivery box is separated from the top surface of the food delivery box next to it, and the vertical distance between the locking rod and the hole wall at the top of the lock hole 41 is gradually reduced to less than h, h=12mm, as shown in FIG. Figure 6 As shown, at this time, the distance between the bottom surface of the upper food delivery box and the top surface of the lower food delivery box is greater than 3mm, so that the spring sheet of the micro switch 42 automatically resets, thereby disconnecting the power of the electromagnetic lock 4, so that the electromagnetic lock 4 retracts the locking rod to unlock, and the card block 3 and the card slot 2 are no longer locked together, so that the delivery person can continue to lift the top food delivery box until the top food delivery box and the food delivery box next to it are completely separated. In other embodiments, the size values ​​of the above-mentioned components can be changed, as long as it is ensured that the locking rod can move vertically in the lock hole 41 and the vertical distance that can be moved is not less than the vertical displacement caused by the squeezing of the spring sheet of the micro switch 42.

[0034] The store is provided with a storage device for storing the food delivery box, and the storage device is provided with a power connection line. The right side wall of the food delivery box is provided with a power plug 72, which is electrically connected to the battery and the DC power supply. After the delivery person delivers the food delivery box to the store, the store places the food delivery box in the storage device, and connects the power connection line of the storage device to the power plug 72 of the food delivery box, so as to charge the battery and supply power to the DC power supply at the same time. When the power plug 72 is connected to the external power line, the controller switches to powering the food delivery box with the DC power supply. In other embodiments, the wireless power supply induction module of the transport vehicle can be changed to a power connection line, or the power connection line in the storage device can be changed to a wireless power supply induction module.

[0035] If the store needs to take out a food packaging box 20, the store will align the QR code corresponding to the food packaging box 20 stored in the mobile phone with the barcode scanner 9. The barcode scanner 9 scans the QR code to obtain the corresponding food packaging box 20 information and sends the information to the controller. The controller determines the number of the corresponding accommodating cavity 10 according to the association between the information of the food packaging box 20 and the number of the accommodating cavity 10, and controls the corresponding electromagnetic lock cylinder 12 to unlock accordingly, and the corresponding closed door 1 will automatically pop open. After the store takes out the required food packaging box 20, it manually closes the closed door 1, and the electromagnetic lock cylinder 12 will automatically re-lock.

[0036] Preferably, the micro switch 42 can be replaced by a magnetic induction switch, wherein the induction coil of the magnetic induction switch is arranged on the bottom surface of the food delivery box and is electrically connected to the electromagnetic lock 4, and the magnet of the magnetic induction switch is arranged on the top surface of the food delivery box. When two food delivery boxes are stacked up and down, the induction coil senses the magnet and the electromagnetic lock 4 is locked.

[0037] In other non-preferred embodiments, the micro switch 42 is changed to an electrically connected controller, and when the micro switch 42 is turned on or off, a corresponding control signal is triggered and transmitted to the controller. In this way, the controller controls the locking and unlocking of the electromagnetic lock 4 according to the control signal.
