[0062] See Figures 1 to 7 This embodiment provides an energy-saving refrigerated truck body, including a box body 10, a first isolation component 20, and a second isolation component 30.

[0063] A refrigeration unit 11 is installed inside the head of the container 10, and an openable tailgate 12 is provided at the rear of the container 10. A first isolation component 20 is disposed inside the container 10, which can divide the internal space of the container 10 along the length of the container 10, and the first isolation component 20 can be opened and closed. A second isolation component 30 is disposed inside the container 10, which can divide the internal space of the container 10 along the length of the container 10, and the second isolation component 30 can be opened and closed. The second isolation component 30 is located between the first isolation component 20 and the tailgate 12, and an unloading area 13 is formed between the first isolation component 20 and the second isolation component 30.

[0064] In this embodiment, the storage area 14 is located in front of the first isolation component 20. Goods are stacked in the storage area 14. When the refrigerated truck needs to unload at a retail outlet, staff enter the truck through the tailgate 12, pass through the second isolation component 30, and then the second isolation component 30 closes to prevent a large amount of hot outside air from entering the unloading area 13. They then pass through the first isolation component 20 and move the goods to the unloading area 13 between the first and second isolation components 20. The first isolation component 20 is then closed (to prevent a large amount of cold air leakage), and the second isolation component 30 is opened to unload the goods from the tailgate 12. During the unloading process, by controlling the opening and closing of the first and second isolation components 20 and 30 respectively, the entry of hot outside air into the truck is reduced, and the leakage of cold air from the truck is minimized, thereby achieving energy conservation.

[0065] In one embodiment, the first isolation component 20 includes a crossbeam 21, a longitudinal beam 22, and an isolation curtain 23.

[0066] Two crossbeams 21 are provided, arranged in parallel. Two longitudinal beams 22 are provided, arranged in parallel, with their upper and lower ends connected to the ends of the two crossbeams 21 respectively. The two longitudinal beams 22 and the two crossbeams 21 form a rectangular mounting frame 24. Multiple isolation curtains 23 are arranged horizontally in parallel, located within the mounting frame 24. The upper end of the isolation curtain 23 is connected to the lower end of the upper crossbeam 21, and the lower end of the isolation curtain 23 can be magnetically connected to the crossbeam 21 below it. The sides of the isolation curtain 23 can be magnetically connected to the sides of the corresponding longitudinal beam 22 or adjacent isolation curtains 23. Specifically, magnetic connection means that both sides and the lower end of the isolation curtain 23 are magnetic, the inner side of the longitudinal beam 22 and the upper end of the lower crossbeam 21 are also magnetic, and the magnetic ends rely on magnetism to approach each other and eventually connect together. The components included in the second isolation component 30 and the connection methods between the components are the same as those included in the first isolation component 20.

[0067] In this embodiment, the side of the isolation curtain 23 can be separated from or connected to the adjacent isolation curtain 23 or longitudinal beam 22 by magnetic attraction, and the lower end of the isolation curtain 23 can be separated from or connected to the lower cross beam 21, thereby realizing the opening and closing of the first isolation component 20.

[0068] In one embodiment, an elastic annular sealing sheet 25 is provided on the outer periphery of the mounting frame 24; the outer ring of the annular sealing sheet 25 is in contact with the inner wall of the housing 10.

[0069] In this embodiment, the mounting frame 24 does not contact the inner wall of the carriage, and the annular sealing sheet 25 contacts the inner wall of the carriage to reduce the leakage of cold air from the outer periphery of the mounting frame 24.

[0070] In one embodiment, sliding holes 26 are provided at both ends of the crossbeam 21 in the first isolation component 20 and at both ends of the crossbeam 21 in the second isolation component 30.

[0071] The energy-efficient refrigerated truck also includes four support rods 40 and a locking device.

[0072] Four support rods 40 are arranged along the length of the housing 10, and are connected to the inner wall of the housing 10. The four support rods 40 are slidably engaged with four sliding holes 26 in the first isolation component 20, and also slidably engaged with four sliding holes 26 in the second isolation component 30. A locking device is used to lock the first isolation component 20 and the second isolation component 30 onto the support rods 40.

[0073] In this embodiment, as the amount of goods in the refrigerated truck decreases after unloading, the first isolation component 20 and the second isolation component 30 can be pushed towards the front of the truck bed, thereby reducing the space of the storage area 14 and thus reducing the space to be refrigerated by the refrigeration device 11, thereby reducing energy consumption.

[0074] In one embodiment, the longitudinal beam 22 of the second isolation component 30 has a mounting hole 31 in the middle, and the longitudinal beam 22 of the first isolation component 20 has a driving hole 27 in the middle. The locking device includes two locking mechanisms 50 arranged symmetrically to each other, and the two locking mechanisms 50 correspond to the two longitudinal beams 22 of the second isolation component 30 respectively.

[0075] The locking mechanism 50 includes a sleeve 51, a drive rod 52, a first limit block 54, and a first drive block 56.

[0076] One end of the sleeve 51 passes through the mounting hole 31 and the drive hole 27 in sequence. The sleeve 51 is rotatably connected to the mounting hole 31 and threadedly connected to the drive hole 27. One end of the drive rod 52 passes through the sleeve 51, and the other end of the drive rod 52 is connected to the turntable 53. The drive rod 52 and the sleeve 51 are clearance-fitted. Multiple first limiting blocks 54 are provided. One end of the first limiting block 54 is connected to the end of the sleeve 51 away from the turntable 53, and the other end of the first limiting block 54 extends along the axial direction of the sleeve 51. A first limiting groove 55 is formed between two adjacent first limiting blocks 54. Multiple first driving blocks 56 are provided. The first driving block 56 is connected to the outer peripheral wall of the drive rod 52. The first driving block 56 can move along the axial direction of the sleeve 51 and be inserted into the corresponding first limiting groove 55. The end of the first limiting block 54 away from the sleeve 51 is a pointed tip, which makes it easier for the first driving block 56 to be inserted into the first limiting groove 55 when it moves along the axial direction of the sleeve 51. The second isolation component 30 is located between the turntable 53 and the first isolation component 20. The first drive block 56 can be circumferentially distributed on the outer peripheral wall of the drive rod 52, and correspondingly, the first limit block 54 is circumferentially distributed around the axis of the sleeve.

[0077] In this embodiment, the drive rod 52 can rotate and slide within the sleeve 51. When the drive rod 52 slides axially along the sleeve 51, the first drive block 56 can slide out from the first limiting groove 55. At this time, the drive rod 52 rotates, but the sleeve 51 does not move. After the drive rod 52 slides axially, the first drive block 56 is inserted into the first limiting groove 55. At this time, the drive rod 52 rotates, causing the sleeve 51 to rotate. Since the sleeve 51 is threadedly connected to the drive hole 27, it causes the first isolation component 20 to move closer to or further away from the second isolation component 30. This allows the size of the unloading area 13 to be controlled according to the volume of everyday goods. Furthermore, the threaded connection between the sleeve 51 and the drive hole 27 allows the first isolation component 20 to remain relatively stationary relative to the second isolation component 30. Then, the locking device only needs to lock the second isolation component 30 onto the support rod 40, and the first isolation component 20 can also remain locked.

[0078] In one embodiment, the lower end of the upper support rod 40 is provided with a plurality of locking grooves 41 arranged along its axial direction; the upper end of the lower support rod 40 is provided with a plurality of locking grooves 41 arranged along its axial direction. The locking mechanism 50 also includes two sets of linkage components 57 symmetrically arranged on the upper and lower sides of the sleeve 51.

[0079] The locking assembly includes a mounting base 571, a slider 575, a bar-shaped locking block 576, a guide rod 577, a spring 578, and a connecting rope 579.

[0080] Mounting base 571 is connected to the longitudinal beam 22 of the second isolation assembly 30. Mounting base 571 has a vertically extending mounting cavity 572. One end of mounting base 571 has a through-hole 573 communicating with the mounting cavity 572, and the other end has a through-hole 574 communicating with the mounting cavity 572. A slider 575 is vertically slidably disposed within the mounting cavity 572. One end of a strip-shaped locking block 576 is connected to the slider 575, and the other end of the strip-shaped locking block 576 passes through the strip-shaped hole 573 and can be inserted into the corresponding locking groove 41. One end of a guide rod 577 is connected to the end of the slider 575 away from the strip-shaped locking block 576, and the other end of the guide rod 577 passes through the through-hole 574. A spring 578 is sleeved on the guide rod 577, and both ends of the spring 578 abut against the slider 575 and the inner wall of the mounting cavity 572, respectively. One end of the connecting rope 579 is connected to the end of the guide rod 577 away from the slider 575. The connecting rope 579 can pull the slider 575 by means of the rotation of the drive rod 52.

[0081] In this embodiment, when the drive rod 52 moves axially, causing the first drive block 56 to disengage from the first limiting groove 55, the drive rod 52 rotates and pulls the connecting rope 579, causing the slider 575 to move towards the drive rod 52 and compress the spring 578. Simultaneously, the strip-shaped locking block 576 moves towards the drive rod 52 and disengages from the locking groove 41, thus unlocking the mounting frame 24 (longitudinal beam 22) and allowing it to slide on the support rod 40. When the drive rod 52 no longer pulls the connecting rope 579, under the action of the spring 578, the slider 575 drives the strip-shaped locking block 576 to insert into the corresponding locking groove 41, thus locking the first isolation component 20 and the second isolation component 30, which are then locked to the support rod 40.

[0082] In one embodiment, the locking mechanism 50 further includes a winding ring 60, a second limiting block 61, and a second driving block 63.

[0083] A winding ring 60 is located between two mounting bases 571. The winding ring 60 is coaxially rotatably sleeved on the sleeve 51, and its upper and lower ends are connected to the corresponding connecting ropes 579. A circumferential winding groove can be formed on the outer periphery of the winding ring 60 for winding and placing the connecting ropes 579. In addition, the winding ring 60 can also be configured to have sufficient length along the axial direction, so as to wind and pull the connecting ropes 579 during rotation. Multiple second limiting blocks 61 are provided. One end of the second limiting block 61 is connected to the end of the winding ring 60 facing the turntable 53, and the other end of the second limiting block 61 extends along the axial direction of the sleeve 51. A second limiting groove 62 is formed between two adjacent second limiting blocks 61. Multiple second driving blocks 63 are provided. The second driving blocks 63 are connected to the outer peripheral wall of the driving rod 52. The second driving blocks 63 can move along the axial direction of the sleeve 51 and be inserted into the corresponding second limiting groove 62. The end of the second limiting block 61 away from the winding ring 60 can be a pointed tip, so that the second driving block 63 can be inserted.

[0084] In this embodiment, as Figure 3 and Figure 6 At this time, the first drive block 56 at the left end of the drive rod 52 is located in the first limiting groove 55. Rotating the drive rod 52 can drive the sleeve 51 to rotate, thereby making the first isolation component 20 and the second isolation component 30 move closer or further apart. Pushing the drive rod 52 to the left, the first drive block 56 disengages from the first limiting groove 55, and the second drive block 63 moves to the left and engages with the second limiting groove 62. Rotating the drive rod 52 causes the winding ring 60 to rotate and pull the connecting rope 579, thereby pulling the sliders 575 on both sides to slide. The strip locking block 576 is withdrawn from the locking groove 41, thereby simultaneously pushing the first isolation component 20 and the second isolation component 30 to move on the support rod 40, thereby controlling the space size of the storage area 14.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
