DETAILED DESCRIPTION OF THE EMBODIMENTS

[0045] In order to further explain the technical solutions in the present invention, the present invention is explained in detail below by the specific embodiments.

[0046] Referring to FIGS. 1 and 2, the fresh product cold chain distribution device of the present invention comprises at least one refrigeration logistics box 2 and a self-service fresh product pickup cabinet 1. The refrigeration logistics box 2 comprises a box body 21, a box cover 22, a side cover 23, a quick-connection plug board 231, a refrigeration device 24, a temperature selection switch 232, and an identification 25; the box body 21 comprises a positioning slot 212 and air guide grooves 211; the refrigeration logistics box 2 is matched and fixedly placed in the self-service pickup cabinet unit cell through the positioning slot 212 and the limiting lock 100 in the self-service pickup cabinet unit cell. The self-service fresh product pickup cabinet 1 comprises a cabinet body 11, a side panel 12, a back panel 13, a top panel 14, a door panel 15, an air channel cover panel 16, an exhaust channel 101, an inlet channel 102, a scanner 17, a touch display screen, 18 and a control panel 103; the cabinet body 11 comprises a plurality of unit cells, each unit cell is provided with a door panel 15, an electric door lock 151, a contact power supply plug 19, a limiting lock 100, inlet holes 1022 of the self-service pickup cabinet unit cell, and exhaust holes 1011 of the self-service pickup cabinet unit cell, and an inlet channel 102 and an exhaust channel 101 are provided between each set of unit cells.

[0047] In the present invention, the refrigeration logistics box 2 equipped with a refrigeration device 24 is used to store fresh products requiring low-temperature preservation during the distribution process. The temperature of the refrigeration logistics box 2 is adjusted through the temperature selection switch 232, and the refrigeration logistics box 2 is continuously powered during the distribution by connecting the power supply interface on the quick-connection plug board 231 of the refrigeration logistics box 2 to the power supply end of the delivery vehicle. In the delivery terminal, the courier scans the identification 25 of the refrigeration logistics box using the scanner 17 on the self-service fresh product pickup cabinet 1 and stores the refrigeration logistics box 2; in the unit cell, the refrigeration logistics box 2 is positioned and fixed by the limiting lock 100, and the refrigeration logistics box 2 is continuously powered through the contact power supply plug 19 and the elastic contact point on the quick-connection plug board 231 of the refrigeration logistics box 2; the heat released by the refrigeration logistics box 2 is discharged through the air channel between unit cells to cool down the unit cell and reduce energy consumption. The self-service fresh product pickup cabinet 1 can store the refrigeration logistics box 2 for a long time, allowing consumers to freely pick up the products. After the consumer takes the fresh products and returns the refrigeration logistics box 2, the courier can retrieve and reuse the refrigeration logistics box 2.

[0048] In the present invention, the refrigeration logistics box 2 equipped with a refrigeration device 24 is used to store fresh products requiring low-temperature preservation during the distribution process. In the delivery terminal, the refrigeration logistics box 2 filled with fresh products is stored in one of the plurality of unit cells on the self-service fresh product pickup cabinet 1, and the refrigeration logistics box 2 is continuously powered through the contact power supply plug 19 and the elastic contact point on the quick-connection plug board 231. By doing so, the temperature during the whole delivery process remains constant, and consumers can pick up the products freely, which ensures the product quality and greatly improves the convenience.

[0049] After receiving the delivery order, the courier puts the refrigeration logistics box 2 containing the products in the rear box of the battery car. In order to guarantee the continuous refrigeration in the distribution process and during the storage period, elastic contact points 2313 and a storage battery standard plug 2314 are provided on the quick-connection plug board 231 of the side cover 23 of the refrigeration logistics box (referring to FIG. 3). During the delivery process, the refrigeration logistics box is powered by connecting the storage battery standard plug to the battery car, and the temperature selection switch 232 is turned on at the same time. According to the product requirements, two preservation modes of refrigeration and freezing can be selected to start the refrigeration device.

[0050] After arriving at the delivery address, the courier aligns the identification 25 of the logistics box with the scanner 17, and the electric door lock 151 and limiting lock 100 of the corresponding unit cell open at the same time. The electronic lock tongue 1001 on the limiting lock is quickly locked into the positioning slot bayonet 213 to limit and fix the logistics box in place. At the same time, the elastic contact points 193 on the contact power supply plug 19 contact the elastic contact points 2313 on the quick-connection plug board 231 to maintain the power supply. Once the electric door lock is closed, the customer receives the pickup information (referring to FIGS. 4 and 5).

[0051] In order to avoid the overhigh temperature in the unit cell caused by the heat dissipated from refrigeration, the self-service fresh product pickup cabinet 1 is provided with an air flow channel, and air guide grooves 211 are formed on the bottom of the logistics box 2. The air enters the unit cell through the inlet holes 1021 of the inlet channel, the inlet channel 102, and the inlet holes 1022 of the unit cell on the inner side of two columns of unit cells. The inlet fan 1023 of the inlet channel maintains a positive air pressure in the inlet channel. The air flows upward and downward through the guide grooves 211 to uniformly bring the heat to the exhaust holes 1011 of the unit cell on the outer side of the two columns of unit cells, and then exits through the exhaust channel 101 and the exhaust holes 1012 of the exhaust channel.

[0052] The customer picks up the products with the pickup information, and the electric door lock 151 of the unit cell and the limiting lock 100 open synchronously. The logistics box 2 can be put back by secondary code scanning after the product is taken out.

[0053] In addition, it should be noted that the scanner and the touch display screen mentioned in the embodiment are all existing structural parts, and will not be described again.

[0054] The self-service fresh product pickup cabinet of the present invention can also be used as a general self-service fresh product pickup cabinet.
