[0033] Combine the following Figures 1 to 8 The multi-temperature zone insulation box of the present invention is described in detail.

[0034] like Figures 1 to 4 As shown, the first aspect of the present invention provides a multi-temperature zone insulation box. The multi-temperature zone insulation box includes a box body 100, a partition assembly 200, a shielding assembly 300 and a driving assembly 400. The box body 100 has a refrigerating chamber inside; the box side wall 110 of the box body 100 is provided with a plurality of cold air holes 112, and the cold air holes 112 are used to transport cold air to the refrigerating chamber. The partition assembly 200 is located in the refrigerating chamber, and the partition assembly 200 and the box body 100 slide in the left and right direction to divide the refrigerating chamber into a plurality of placement spaces 120. The shielding assembly 300 is arranged perpendicular to the partition assembly 200, and the shielding assembly 300 and the box body 100 slide in the left and right direction to shield part of the cold air holes 112 located in the placement space 120, so that the refrigerating chamber has multiple temperature zones. The driving component 400 is connected to the partition component 200 and the shielding component 300 , and is used to drive the partition component 200 and the shielding component 300 to move synchronously along the left and right directions to adjust the space size of the placement space 120 .

[0035] In this embodiment, by providing a cold air through hole 112 in communication with the refrigerating chamber on the side wall 110 of the box body, cold air can be introduced into the refrigerating chamber through the cold air through hole 112. By providing a shielding component 300, the shielding component 300 can be used to shield part of the cold air through hole 112 in the placement space 120, so that the refrigerating chamber can have multiple temperature zones, achieving the purpose of multi-temperature zone refrigeration. By providing a partitioning component 200 that can move left and right relative to the refrigerating chamber in the refrigerating chamber, and the partitioning component 200 can divide the refrigerating chamber into multiple placement spaces 120, and then combined with the driving component 400, the space size of each placement space 120 can be adjusted according to actual needs, thereby solving the problem that the multiple temperature zone spaces in the multi-temperature zone insulation box in the prior art are relatively fixed.

[0036] In addition, by providing a shielding component 300 that can move left and right relative to the box body 100, and cooperating with the driving component 400, the driving component 400 can drive the shielding component 300 and the partition component 200 to move synchronously, so that the shielding component 300 always partially blocks the cold air holes 112 in the placement space 120, so that the refrigeration temperature in each placement space 120 can be adjusted synchronously.

[0037] like Figure 3 As shown, in some embodiments, a second installation gap 111 is formed in the box side wall 110 along the left-right direction; the cold air through hole 112 includes a first through hole section 113 and a second through hole section 114; the first through hole section 113 is used to transport cold air to the second installation gap 111; the second through hole section 114 is used to connect the second installation gap 111 and the refrigerating chamber so that cold air enters the refrigerating chamber; the shielding component 300 is located in the second installation gap 111 and is used to shield the second through hole section 114. By setting the second installation gap 111 and the shielding component 300 being located in the second installation gap 111, it is possible to avoid the shielding component 300 occupying the space of the refrigerating chamber, which can not only improve the utilization rate of the refrigerating space of the refrigerating chamber, but also make the multi-temperature zone insulation box more beautiful as a whole and avoid the shielding component 300 being exposed.

[0038] In some embodiments, an external cold source can be introduced into the refrigerating chamber through the cold air through hole 112 .

[0039] like Figure 4 and Figure 8 As shown, in some other embodiments, a first installation gap is further formed in the box side wall 110, the first installation gap and the second installation gap 111 are arranged parallel to each other along the front-to-back direction, and the first through hole section 113 is used to connect the first installation gap and the second installation gap 111; a refrigeration medium delivery pipe 510 is arranged in the first installation gap. By arranging the refrigeration medium delivery pipe 510 in the first installation gap, the refrigeration medium delivery pipe 510 can cool the air, and the cooled space enters the second installation gap 111 through the first through hole section 113, and then enters the refrigeration chamber from the second through hole section 114, thereby cooling the refrigeration chamber.

[0040] It can be understood that the inlet of the refrigerant delivery pipe is communicated with the outlet of the condenser 520, the outlet of the refrigerant delivery pipe is communicated with the inlet of the compressor 530, and the outlet of the compressor 530 is communicated with the inlet of the condenser 520. The refrigeration medium can be recycled.

[0041] like Figure 8As shown, further, the refrigerant medium delivery pipe 510 includes a main delivery pipe 511, an expansion valve 512 and a capillary pipe 513. The inlet of the main delivery pipe 511 is used to communicate with the outlet of the condenser 520. The inlet of the expansion valve 512 is communicated with the outlet of the main delivery pipe 511. The inlet of the capillary pipe 513 is communicated with the outlet of the expansion valve 512, and the outlet of the capillary pipe 513 is used to communicate with the inlet of the compressor 530; the diameter of the capillary pipe 513 is smaller than the diameter of the main delivery pipe 511.

[0042] The compressor 530 delivers the refrigerant to the condenser 520, and the condenser 520 conducts the refrigerant to the main delivery pipe 511, and pumps the refrigerant into the capillary pipe 513 through the expansion valve 512, so that the temperature of the refrigerant in the capillary pipe 513 decreases, thereby cooling the refrigerating chamber, and finally the refrigerant is conducted back to the compressor 530. The temperature of the refrigerant in the capillary pipe 513 decreases, and the outer wall of the capillary pipe 513 generates cold air, which enters the refrigerating chamber through the first through hole section 113 and the second through hole section 114, thereby cooling the refrigerating chamber.

[0043] Furthermore, a mounting cavity is formed inside the box body 100, and the mounting cavity is arranged in parallel with the refrigerating chamber. The condenser 520 and the compressor 530 are arranged in the mounting cavity.

[0044] like Figure 8 As shown, in some embodiments, the multi-temperature zone insulation box further includes a heat conducting component 600; the heat conducting component 600 is arranged in the first installation gap, one end of the heat conducting component 600 is used to connect with the compressor 530, and the other end extends toward the end away from the compressor 530, so as to make the heat generated by the compressor 530 transfer in a unidirectional manner along the left and right directions. Specifically, the compressor 530 is arranged at the left end of the first installation gap, the heat conducting component 600 is located in the first installation gap, the left end of the heat conducting component 600 is connected to the compressor 530, and the right end extends toward the right end of the first installation gap, and the heat conducting component 600 can make the heat generated by the compressor 530 transfer along the heat conducting component 600. Considering that heat is lost during the transfer process, the temperature difference between the two adjacent placement spaces 120 can be further improved by setting the heat conducting component 600, and the temperature difference between the two placement spaces 120 at both ends can be further increased.

[0045] Further, the heat conducting assembly 600 includes a heat conducting plate, which is arranged in the left-right direction, one end of which is connected to the compressor 530, and the other end of which extends unidirectionally in the left-right direction. Preferably, the heat conducting plate is a metal plate.

[0046] In some embodiments, an air inlet pipe is installed at the air inlet end of the condenser 520, and a filter plate is installed in the air inlet pipe.

[0047] like Figure 2 , Figure 4and Figure 5 As shown, in some embodiments, the partition assembly 200 includes a plurality of partitions; along the left-right direction, the plurality of partitions are parallel to each other and spaced apart in the refrigerating chamber, and are used to divide the refrigerating chamber into a plurality of placement spaces 120; the partitions are slidably matched with the box body 100 along the left-right direction. Specifically, the driving assembly 400 is connected to the plurality of partitions, and is used to drive the partitions to move along the left-right direction. The size of each placement space 120 can be changed according to actual needs by driving the partitions.

[0048] like Figure 4 and Figure 5 As shown, the partition assembly 200 includes two partitions, which are named as a first partition 211 and a second partition 212 for ease of description; the first partition 211 and the second partition 212 are arranged at intervals on the left and right to divide the refrigerator into a first placement space 121, a second placement space 122 and a third placement space 123, as shown in FIG. Figure 2 As shown, the three placement spaces 120 are arranged in parallel along the left-right direction. The driving assembly 400 can drive the first partition 211 to move left and right alone, can drive the second partition 212 to move left and right alone, and can also drive the first partition 211 and the second partition 212 to move left or right synchronously at the same time.

[0049] It is understandable that the specific number of the partitions is not limited in this embodiment, and the number of the partitions can be two, three, or four.

[0050] like Figure 4 and Figure 7 As shown, in some embodiments, the shielding assembly 300 includes a plurality of baffles; the plurality of baffles correspond to the partitions one by one, and the baffles are arranged perpendicular to the partitions; the baffles slide and cooperate with the box body 100 in the left-right direction. By providing a plurality of baffles, the baffles can be made to move synchronously with the corresponding partitions, and the baffles can be used to shield part of the second through hole section 114 in the placement space 120.

[0051] Specifically, the areas of the baffles in two adjacent placement spaces 120 are different. By placing baffles of different areas in two adjacent placement spaces 120, a temperature difference can be formed in the adjacent placement spaces 120, which is suitable for placing items with different temperature requirements.

[0052] like Figure 4 and Figure 7 As shown, illustratively, the shielding assembly 300 includes two baffles. For ease of description, the two baffles are named as the first baffle 311 and the second baffle 312. The first baffle 311 corresponds to the first baffle 211, and the second baffle 312 corresponds to the second baffle 212. The first baffle 311 moves synchronously with the first baffle 211, and the second baffle 312 moves synchronously with the second baffle 212.

[0053] It is understandable that in this embodiment, there is no limitation on the specific number of baffles, and the number of baffles can be two, three, or four.

[0054] It should be noted that a plurality means at least two.

[0055] Exemplarily, the cross section of the first baffle 311 is T-shaped, and the cross section of the second baffle 312 is rectangular. The area of ​​the second baffle 312 is larger than the area of ​​the first baffle 311. The second baffle 312 is used to cover part of the second through hole section 114 in the second placement space 122, and the first baffle 311 is used to cover part of the second through hole section 114 in the first placement space 121. Figure 2 shown.

[0056] like Figures 4 to 7 As shown, in some embodiments, the driving assembly 400 includes a plurality of first transmission members 410, a transmission structure 420, a plurality of second transmission members 430 and a driving member 440. The plurality of first transmission members correspond to the plurality of said plates one by one; the first transmission member 410 is connected to the corresponding partition. The plurality of second transmission members 430 correspond to the plurality of first transmission members 410 one by one; the second transmission member 430 is transmission-connected to the corresponding first transmission member 410 through the transmission structure 420, and the second transmission member 430 is connected to the corresponding baffle. The driving member 440 is connected to the first transmission member 410, and is used to drive the second transmission member 430 through the first transmission member 410, so that the corresponding partition and baffle move synchronously in the left-right direction; or, the driving member 440 is connected to the second transmission member 430, and is used to drive the first transmission member 410 through the second transmission member 430, so that the corresponding partition and baffle move synchronously in the left-right direction.

[0057] By providing a first transmission member 410 corresponding to each partition, a partition can be driven separately, so that one partition moves in the left-right direction, while the other partition can remain stationary. By providing a second transmission member 430, and connecting the second transmission member 430 to the first transmission member 410 through the transmission structure 420, the partition and the baffle can move synchronously.

[0058] Further, a placement slot is provided on the box body 100, and the driving member 440 is placed in the placement slot. When in use, the driving member 440 is taken out from the placement slot. When not needed, the driving member 440 is placed in the placement slot.

[0059] In some other embodiments, the plurality of first transmission members 410 may also be connected to each other via a transmission structure 420, so that the plurality of partitions can move synchronously.

[0060] Furthermore, the transmission structure 420 includes a transmission belt.

[0061] Furthermore, the first transmission member 410 includes two first horizontal screw rods 411. The two first horizontal screw rods 411 are located in the cold storage room, and along the front-to-back direction, the two first horizontal screw rods 411 are parallel to each other and spaced apart, and the corresponding partitions are threadedly matched with the two first horizontal screw rods 411; one end of the first horizontal screw rod 411 is transmission-connected to the corresponding second transmission member 430 through the transmission structure 420, and the other end of the first horizontal screw rod 411 is connected to the driving member 440; the left and right movement of the partition is achieved through the screw nut structure, and the structure is simple and the operation is stable.

[0062] like Figure 5 and Figure 6 As shown, further, the first transmission member 410 further includes a bevel gear set 412 and a first transmission rod 413; one end of the first transmission rod 413 is connected to the driving member 440, and the other end is transmission-connected to the other end of the first horizontal screw rod 411 through the bevel gear set 412. By providing the first transmission rod 413 and the bevel gear set 412, the rotation in the non-horizontal direction can be converted into the horizontal rotation of the first horizontal screw rod 411, thereby expanding the arrangement of the driving member 440.

[0063] Specifically, the bevel gear set 412 includes a first bevel gear 414 and a second bevel gear 415; one end of the first transmission member 410 is connected to the first bevel gear 414, and one end of the first horizontal screw rod 411 away from the transmission structure 420 is connected to the second bevel gear 415, and the first bevel gear 414 and the second bevel gear 415 are meshed and connected.

[0064] Specifically, along the axial direction of the first transmission rod 413 , the first transmission rod 413 is provided with a mounting hole, and the driving member 440 is installed in the mounting hole.

[0065] Preferably, the cross section of the mounting hole is hexagonal. The cross section of the driving member 440 is hexagonal.

One of the second screw rods is connected to a first horizontal screw rod 411 of the corresponding first transmission member 410 through the transmission structure 420, so as to realize the synchronous movement of the partition and the baffle.

[0067] like Figure 4 and Figure 5As shown, illustratively, the drive assembly 400 includes two first transmission members 410. The two first transmission members 410 are spaced apart in the up-and-down directions in the cold storage chamber. The first horizontal screw rod 411 of the upper first transmission member 410 is threadedly connected to the first partition 211, and slides with the second partition 212 in the left-right direction; the first horizontal screw rod 411 of the lower first transmission member 410 is threadedly connected to the second partition 212, and slides with the first partition 211 in the left-and-right direction. The two first horizontal screw rods 411 of the same first transmission member 410 are connected by a transmission belt. For the upper first transmission member 410, driving any one of the first horizontal screw rods 411 to rotate can make the two first horizontal screw rods 411 rotate synchronously, so that the first partition 211 moves in the left-and-right direction, and the second partition 212 does not move in the left-and-right direction at this time. For the first transmission member 410 below, driving any one of the first horizontal screw rods 411 to rotate can make the two first horizontal screw rods 411 rotate synchronously, so that the second partition plate 212 moves in the left and right direction, and the first partition plate 211 does not move in the left and right direction.

[0068] like Figure 7 As shown, illustratively, the drive assembly 400 includes two second transmission members 430. Both second transmission members 430 are arranged in the second installation gap 111. The second horizontal screw rod 431 of the first second transmission member 430 is threadedly connected to the first baffle 311, and slides with the second baffle 312 in the left-right direction. The second horizontal screw rod 431 of the second second transmission member 430 is threadedly connected to the second baffle 312, and slides with the first baffle 311 in the left-right direction. The two second horizontal screw rods 431 of the same second transmission member 430 are connected by synchronous belt transmission, and one of the second horizontal screw rods 431 is connected by synchronous belt transmission to the first horizontal screw rod 411 of the corresponding first transmission member 410.

[0069] The working process of the multi-temperature zone insulation box of this embodiment is described below by taking the driving assembly 400 including two first transmission members 410 and two second transmission members 430 as an example.

[0070] When the transport personnel use the multi-temperature zone insulated box to transport goods, the transport personnel first place the goods of different sizes on one side of the multi-temperature zone insulated box, and then open the front cover 130 of the box body 100, and adjust the first partition 211 and the second partition 212 according to the sizes of the multiple goods and the required temperature zones.

[0071] When adjusting the first partition 211, the transportation personnel takes the driving member 440 and inserts one end of the driving member 440 into the installation groove of the first transmission rod 413 of the first transmission member 410 located above, and rotates the driving member 440 to drive the first transmission rod 413 to rotate, thereby driving the first bevel gear 414 to rotate, and the first bevel gear 414 and the second bevel gear 415 are meshed and connected, so the second bevel gear 415 rotates, thereby driving a first horizontal screw rod 411 of the first transmission member 410 above to rotate, and the two first horizontal screw rods 411 are connected by a synchronous belt, so the two first horizontal screw rods 411 rotate synchronously.

[0072] When the two first horizontal screw rods 411 of the first transmission member 410 located at the top rotate, the outer walls of the two first horizontal screw rods 411 are respectively threadedly connected to the front and rear sides of the first partition 211, and slidingly cooperate with the front and rear sides of the second partition 212. Therefore, the first partition 211 moves left and right, and the second partition 212 does not move, thereby realizing the adjustment of the space size of the first placement space 121 and the second placement space 122.

[0073] When adjusting the second partition 212, one end of the driving member 440 is inserted into the installation groove of the first transmission rod 413 of the first transmission member 410 located below, and the driving member 440 is rotated to drive the first transmission rod 413 to rotate, thereby driving the first bevel gear 414 to rotate, and the first bevel gear 414 and the second bevel gear 415 are meshed and connected, so the second bevel gear 415 rotates, thereby driving a first horizontal screw rod 411 of the first transmission member 410 above to rotate, and the two first horizontal screw rods 411 are connected by a synchronous belt, so the two first horizontal screw rods 411 rotate synchronously.

[0074] When the two first horizontal screw rods 411 of the first transmission member 410 located below rotate, the outer walls of the two first horizontal screw rods 411 are respectively threadedly connected to the front and rear sides of the second partition 212, and the outer walls of the two first horizontal screw rods 411 are respectively slidably matched with the front and rear sides of the first partition 211 left and right, so the two groups of second partitions 212 are displaced, and the first partition 211 is not displaced, thereby realizing the adjustment of the space size of the second placement space 122 and the third placement space 123.

[0075] When the two first horizontal screw rods 411 of the first transmission member 410 located above rotate, the first horizontal screw rod 411 is connected to a second horizontal screw rod 431 of the corresponding second transmission member 430 through a synchronous belt, so the two second horizontal screw rods 431 of the corresponding second transmission member 430 rotate synchronously, thereby driving the corresponding first baffle 311 to move, and the second baffle 312 does not move, and the first baffle 311 blocks part of the second through hole section 114 of the first placement space 121.

[0076] When the two first horizontal screw rods 411 of the first transmission member 410 located below rotate, the first horizontal screw rod 411 is connected to a second horizontal screw rod 431 of the corresponding second transmission member 430 through a synchronous belt, so the two second horizontal screw rods 431 of the corresponding second transmission member 430 rotate synchronously, thereby driving the second baffle 312 to move, and the first baffle 311 does not move. The second baffle 312 blocks part of the second through hole section 114 of the second placement space 122.

[0077] The area of ​​the first baffle 311 is larger than that of the second baffle 312 , so the number of air outlets blocked by the first baffle 311 is greater than the number of air outlets blocked by the second baffle 312 .

[0078] The transport personnel place the goods of different sizes into the first placement space 121, the second placement space 122 and the third placement space 123 after space adjustment, and then the operator closes the front cover 130 and starts the compressor 530 and the condenser 520 through the control panel arranged on the box body 100, so that the capillary duct 513 generates cold air, and introduces the cold air into the first placement space 121, the second placement space 122 and the third placement space 123 through the cold air through hole 112. The arrangement of the first baffle 311 and the second baffle 312 generates a certain temperature difference between the first placement space 121, the second placement space 122 and the third placement space 123.

[0079] When the condenser 520 is running, the condenser 520 draws gas from the outside of the box body 100 into the condenser 520 through the air inlet pipe, dissipates heat from the condenser 520, and the gas that absorbs heat is discharged from the heat conduction plate, and the first baffle 311 and the second baffle 312 successively absorb the heat inside the heat conduction plate, further increasing the temperature difference between the first placement space 121, the second placement space 122 and the third placement space 123, so that the temperature difference between the first placement space 121, the second placement space 122 and the third placement space 123 is between five degrees Celsius and ten degrees Celsius.

[0080] The present invention provides the first partition 211 and the second partition 212. When the transport personnel place goods of different sizes, the spaces of the first placement space 121, the second placement space 122 and the third placement space 123 are adjusted accordingly, so that goods of different sizes can be placed in different placement spaces 120, thereby improving the practicality of the thermal insulation box.

[0081] The second aspect of the present invention provides a transport device. The transport device includes the multi-temperature zone insulation box of any of the above embodiments. Therefore, the transport device of this embodiment has at least the above advantages, which will not be described in detail here.

[0082] Furthermore, the transportation equipment includes cold chain transport boxes or special cabinets for luggage and parcels.

[0083] Furthermore, the transportation equipment may be a cold chain transport vehicle, a high-speed train or a motor vehicle.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
