[0052] The first sensor 9, the second sensor 8 and the first reciprocating motor 3 are all connected to the picking control system (supplementary picking control system diagram); in this embodiment, the first opening and closing door 101 and the second opening and closing door 102 are both transparent doors. This embodiment also provides a smart freezer, including a first delivery control system and a first sales terminal, and also includes a commercial freezer and a picking device, the commercial freezer and the picking warehouse body 1 are respectively arranged on both sides of the lifting door 2 symmetrically; the commercial freezer includes two storage warehouses of different specifications, each storage warehouse corresponds to a picking warehouse, each storage warehouse is provided with a delivery mechanism for moving goods to the picking warehouse, and the delivery mechanism and the picking control system are both connected to the first delivery control system in communication;

[0053] In this embodiment, the delivery mechanism can be a flat push structure 600 or a spring push structure 500, which can be used for the sale of fragile goods, expanding the range of goods that can be automatically sold. The flat push structure 600 or the spring push structure 500 are structures existing in the prior art, so the working principle and structure are not described in detail here; Figure 7 As shown, it is a schematic diagram of the spring push structure 500, wherein 501 is a spring, 502-a motor and a driving assembly, 503-a pallet main frame, and 504-a pallet track. When shipment is required, the motor and the driving assembly 502 work, the spring pushes the goods to move, and the goods enter the pickup bin from the opening end to realize the shipment of the goods; Figure 8 As shown, it is a schematic diagram of the push structure 600, wherein 601-motor and drive device; 602-insertable partition; 603-track; 604-pallet base frame; 605-pallet mounting frame, when it is necessary to ship, the motor and drive device 601 drive the track 603 to rotate, and the goods on the track 603 reach the opening end and enter the shipping warehouse; the first shipping control system is an existing automatic vending control system.

[0054] The working principle of this embodiment is as follows: after the consumer selects the desired goods through the first vending terminal and pays, the delivery mechanism receives the delivery signal from the first vending terminal and sends the signal to the pickup control system at the same time. The pickup control system determines whether the first pickup warehouse or the second pickup warehouse is to receive goods and determines the position of the lifting door 2, thereby giving a forward or reverse signal to the first reciprocating motor 3 to start; such as: when the first pickup warehouse is to receive goods and the lifting door 2 is located between the first pickup warehouse and the delivery mechanism, the first reciprocating motor 3 rotates in the opposite direction to make the lifting door 2 move downward and move until it contacts the second sensor 8. The second sensor 8 transmits a signal to the pickup control system, which transmits a signal to the first delivery control system. The first delivery control system controls the delivery mechanism to move, and the delivery mechanism starts to push the first commodity 13 to the first pickup warehouse. After the commodity detector in the first pickup warehouse detects the first commodity 13, it transmits a signal to the pickup control system. The pickup control system controls The first reciprocating motor 3 rotates forward to move the lifting door 2 upward and move it to contact the first sensor 9, separating the first pickup bin from the delivery mechanism. The first sensor 9 transmits a signal to the pickup control system, and the pickup control system controls the first electromagnetic lock 16 to lose power. Then, the first opening and closing door 101 can be opened to a certain angle under the action of the elastic force of the first electromagnetic lock 16, so that the consumer can flip the first opening and closing door 101 to take away the first commodity 13. After the first commodity 13 is taken away, the commodity detector transmits a signal of whether there is a commodity to the pickup control system, and the pickup control system controls the first electromagnetic lock 16 to be energized, and the first opening and closing door 101 is locked again. It is worth noting that: in the above-mentioned entire pickup process, although the second pickup bin is in a connected state with the delivery mechanism, the second electromagnetic lock 15 is always energized, so the second opening and closing door 102 is always in a locked state, thereby preventing consumers from taking away the commodities in the delivery mechanism from the second pickup bin, thereby playing an anti-theft role.

[0055] When the second picking warehouse is about to receive goods and the lifting door 2 is located between the first picking warehouse and the shipping mechanism, the first sensor 9 transmits a position signal of the lifting door 2 to the picking control system, and the picking control system transmits a signal to the first shipping control system to control the movement of the shipping mechanism. The shipping mechanism starts to push the first commodity 13 to the first picking warehouse, and the commodity detector in the second picking warehouse detects the second commodity 14 and transmits a signal to the picking control system. The picking control system controls the first reciprocating motor 3 to rotate in the opposite direction so that the lifting door 2 moves downward and moves to contact the second sensor 8, separating the second picking warehouse from the shipping mechanism. The second sensor 8 transmits a signal to the picking control system, and the picking control system controls the second electromagnetic lock 15 to lose power, then the second opening and closing door 102 is in the first picking warehouse. The second electromagnetic lock 15 can be opened to a certain angle under the action of elastic force, so that the consumer can flip over the second opening and closing door 102 to take away the second commodity 14. After the second commodity 14 is taken away, the commodity detector will transmit the signal of whether there is a commodity to the picking control system, and the picking control system will control the second electromagnetic lock 15 to be energized to lock the second opening and closing door 102 again. It is worth noting that: in the above-mentioned entire picking process, before and during shipment, the first picking warehouse and the shipping mechanism are in a separated state, but after shipment, the first picking warehouse and the shipping mechanism are in a connected state, and the first electromagnetic lock 16 is always energized. Therefore, the first opening and closing door 101 is always in a locked state, thereby preventing consumers from taking away the commodities in the shipping mechanism through the first picking warehouse, thereby playing an anti-theft role.

[0056] Example 2

[0057] What is different from Example 1 is that the structure of the lifting mechanism in this embodiment is different, specifically: the lifting mechanism includes a belt conveyor and a second transmission shaft and a third transmission shaft that pass through the cargo pickup warehouse body 1, one end of the second transmission shaft and one end of the third transmission shaft are both provided with a second drive motor, one end of the second transmission shaft and one end of the third transmission shaft are respectively connected to the output shaft of one of the second drive motors, the second transmission shaft and the third transmission shaft are respectively arranged at the top and bottom of the cargo pickup warehouse body 1, the second transmission shaft and the third transmission shaft are both arranged parallel to the lifting door 2 up and down, two transmission wheels are each sleeved on the second transmission shaft and the third transmission shaft are both interference fit with the transmission wheels, the belt conveyor is sleeved outside the two transmission wheels, and the belt conveyor is detachably and washably connected to the lifting door 2.

[0058] Working principle: The two second drive motors drive the second transmission shaft and the third transmission shaft to rotate in the same direction respectively, and the transmission wheel drives the belt conveyor to rotate, thereby driving the lifting door 2 to move upward or downward to change the position of the lifting door 2, so as to connect or isolate the first pickup warehouse or the second pickup warehouse from the shipping mechanism.
