[0019] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the specification drawings and specific implementation modes.
[0020] The embodiment of the present application discloses a combined cold chain logistics box. Refer to Figure 1 , Figure 2 and Figure 3 , including the logistics box main body. The logistics box main body includes a box body 11 with an open top and a box cover 12 movably arranged at the top opening of the box body 11. The logistics box main body is provided with a cold air channel 3 and an air outlet channel 4. The air inlet of the cold air channel 3 is vertically upward, the air outlet of the cold air channel 3 is communicated with the inside of the logistics box main body, a first overlapping port 31 which is vertically downward and adapted to the air inlet of the cold air channel 3 is opened on the cold air channel 3, the air outlet of the air outlet channel 4 is vertically upward, the air outlet of the air outlet channel 4 is communicated with the inside of the logistics box main body, a second overlapping port 41 which is vertically downward and adapted to the air outlet of the air outlet channel 4 is opened on the air outlet channel 4, and sealing components are movably arranged in both the first overlapping port 31 and the second overlapping port 41. The logistics box of the embodiment of the present application further includes an air inlet pipe 5, an air outlet pipe 6 and an air blower 7. The air inlet pipe 5 is connected to the cold air channel 3 of the topmost logistics box main body among the overlapping logistics box main bodies, the air outlet pipe 6 is connected to the air outlet channel 4 of the topmost logistics box main body among the overlapping logistics box main bodies, and the air blower 7 is arranged in the air inlet pipe 5 / air outlet pipe 6.
[0021] The sealing components in the first overlapping port 31 and the second overlapping port 41 are in a normally closed state. When the logistics box main bodies are placed overlappingly, the cold air channel 3 and the air outlet channel 4 on the lower logistics box main body cooperate with the corresponding first overlapping port 31 and second overlapping port 41 on the upper logistics box main body respectively to open the sealing components. Through the air blower 7, the cold air in the cold storage truck compartment is sent into the overlapping and connected logistics box main bodies through the cold air channel 3, and the air in the logistics box main body is discharged into the compartment through the air outlet channel 4 and the air outlet pipe 6, avoiding inconsistent internal temperatures of the overlappingly placed logistics box main bodies and improving the refrigeration and heat preservation effect on the goods.
[0022] Further, the end of the air inlet pipe 5 away from the cold air channel 3 and the end of the air outlet pipe 6 away from the air outlet pipe 6 face in opposite directions, so that the air inlet and suction areas of the blower 7 are staggered from the air outlet area of the air outlet pipe 6, and the cold air in the carriage can be effectively introduced into the main body of the logistics box, improving the refrigeration effect on the goods. Multiple branch pipes can be connected to the air inlet pipe 5 and the air outlet pipe 6, and each branch pipe is respectively connected to the cold air channel 3 and the air outlet channel 4 at the top of each vertically overlapped main body of the logistics box.
[0023] In the embodiment of the present application, a support step 111 is protrudingly provided on the inner wall of the box body 11. The support steps 111 are arranged in multiple layers at intervals in the vertical direction in the box body 11. A diffuser plate 8 and a placement plate 9 are provided in the box body 11. The diffuser plate 8 is placed on the support step 111 at the lowermost layer in the box body 11. There are multiple placement plates 9, which are placed on the support steps 111 of other layers in the box body 11. A plurality of first ventilation holes 81 are opened on the diffuser plate 8. The diffuser plate 8 is movably placed on the support step 111. The air outlet of the cold air channel 3 is located below the diffuser plate 8, and the air inlet of the air outlet channel 4 is located above the diffuser plate 8. A plurality of placement grooves 91 for positioning and placing goods are provided on the placement plate 9. A plurality of second ventilation holes 92 are also penetrated between the placement grooves 91 on the placement plate 9. Access ports 93 for people to pass through are opened on both side edges of the placement plate 9. The positions of the first ventilation holes and the second ventilation holes correspond one by one. The cold air introduced into the box body 11 is dispersed and sent out from the first ventilation holes through the diffuser plate 8. After the cold air passes through each layer of the placement plate 9, it finally discharges from the air outlet channel 4.
[0024] Specifically, a first inner sleeve 32 and a second inner sleeve 42 are respectively provided in the first overlapping port 31 and the second overlapping port 41. The air inlet of the cold air channel 3 is inserted between the first overlapping port 31 and the first inner sleeve 32, and the air outlet of the air outlet channel 4 is inserted between the second overlapping port 41 and the second inner sleeve 42. The sealing assembly includes a cover plate 21, a torsion spring 22 and a roller 23. Installation steps 24 are provided on the inner walls of the first inner sleeve 32 and the second inner sleeve 42. The cover plate 21 is rotatably arranged in the first inner sleeve 32 and the second inner sleeve 42. The torsion spring 22 is used to drive the movable end of the cover plate 21 to rotate downward to cooperate with the installation step 24 to close the first inner sleeve 32 / the second inner sleeve 42. Installation brackets are fixedly connected in the cold air channel 3 and the air outlet channel 4, and the roller 23 is rotatably arranged on the installation bracket. When the main bodies of the logistics boxes overlap each other, the roller 23 on the lower-layer main body of the logistics box extends into the first inner sleeve 32 and the second inner sleeve 42, and the roller 23 contacts the cover plate 21 and pushes the cover plate 21 to turn upward and open, so that the cold air channels 3 and the air outlet channels 4 of the upper and lower-layer main bodies of the logistics box are communicated.
[0025] Furthermore, a clearance groove 13 adapted to the cold air channel 3 and the air outlet channel 4 is opened on the side wall of the logistics box body. By accommodating the cold air channel 3 and the air outlet channel 4 through the clearance groove 13, the volume of the logistics box body can be simplified, so that the logistics box body can be stored in and out, thereby improving the effective storage rate of the logistics box body in the vehicle body.
