One end of the hinge part 430 is rotatably connected to the rotating shaft, and the other end is fixed to the outer end face of the door body 20.

[0087] In other words, the outer end surface of the side plate member 13 is provided with a fixed part 410, and the door body 20 is connected to the opening surrounded by the side plate member 13 and the top plate member 11 through a hinge part 400. The hinge part is connected to the outer wall of the door body 20 to realize that the outer wall of the door body 20 is flush with the end surface of the side plate member 13 in the closed state.

[0088] The hinge part is rotatable relative to the fixed part 410 along the rotating shaft part 420 to realize the rotation of the door body 20 relative to the side plate member 13, thereby realizing the opening and closing of the refrigeration chamber. The structure of the hinge part is simple, and the stability of the connection is strong.

[0089] In some embodiments of the present application, a plurality of hinge parts 400 are provided corresponding to each door body 20 along the height direction of the door body 20.

[0090] The hinge parts 400 are arranged between the door body 20 and the side plate member 13, which is beneficial to improve the connection strength of the door body 20 and reduce the connection gap of the door body 20.

[0091] Specifically, the hinge part 430 includes a connecting segment 431, a transition segment 432, and a rotating segment 433. The connecting segment 431 is parallel to the outer end surface of the door body 20 and is fixedly connected to the outer end surface of the door body 20. The transition segment 432 is arranged at an angle with the connecting segment 431. The rotating segment 433 is a curled edge structure formed at the other end of the transition segment 432, and the rotating segment 433 is sleeved outside the rotating shaft part 420.

[0092] A plurality of fixing holes are provided on the connecting segment 431. Fasteners such as screws 120 are fixed to the outer side of the door body 20 through the fixing holes of the connecting segment 431 to realize the stability of the connection between the hinge part and the door body 20. The transition segment 432 is arranged at an angle with the connecting segment 431 to adapt to the difference in the connection position between the two ends of the hinge part 430 and the door body 20 and the fixed part 410.

[0093] In some embodiments of the present application, the fixed part 410 includes a fixed bottom plate 411 and a connecting stand 412 formed at both ends of the fixed bottom plate 411. The two ends of the rotating shaft part 420 are fixed to the two oppositely arranged connecting stands 412, respectively.

[0094] The two connecting stands 412 on each fixed part 410 are arranged in an up-down manner. The two ends of the rotating shaft part 420 are fixed to the corresponding two connecting stands 412 through a first fastening part 421 and a second fastening part 422, respectively, to realize the connection and fixation of the rotating shaft part 420.

[0095] In some embodiments of the present application, the first fastening part 421 is a screw fixed to the upper end of the rotating shaft part 420. The other end of the rotating shaft part 420 is provided with a threaded segment. The second fastening part 422 is a nut structure which is threadedly connected to the rotating shaft part 420.

[0096] During installation, first fix the first fastening part 421 to one end of the rotating shaft part 420. Then, pass the rotating shaft part 420 through the connecting holes on the two connecting uprights 412. Since the end size of the first fastening part 421 is larger than the connecting hole, one end of the rotating shaft part 420 can be connected and limited by the first fastening part 421. After the other end of the rotating shaft part 420 passes through the two connecting holes, tighten the second fastening part 422 on the threaded section to achieve the connection and fixation of the rotating shaft part 420.

[0097] The rotating section 433 is pre-placed between the two connecting uprights 412 so that the rotating shaft 420 can pass directly through the gap in the middle of the rotating section 433, thus achieving a rotatable connection between the rotating section 433 and the rotating shaft 420.

[0098] The compartment 10 has a refrigerated cavity, which is equipped with refrigeration equipment for cooling the refrigerated cavity.

[0099] refer to Figures 6-9 In order to improve the refrigeration effect of the compartment 10 and reduce the loss of cold energy, a sealing structure 600 is provided between the door 20 and the compartment 10. The sealing structure 600 is specifically connected to the end wall where the door 20 and the compartment 10 are in contact, so as to seal the gap between the door 20 and the compartment 10 when closed.

[0100] The sealing structure 600 includes a connecting part 610 and an outer sealing section 620. The connecting part 610 is fixedly connected to the end wall of the door body 20, that is, it is specifically connected to the end wall of the door body 20 that is in contact with the outer panel, the top panel 11 and the bottom panel 14.

[0101] The outer sealing section 620 is formed on the outside of the connecting part 610 and extends towards the outer wall of the compartment 10. When the door 20 is closed, the outer sealing section 620 extends to the outer wall of the compartment 10. In addition to directly sealing the door 20 and the compartment 10 through the connecting part 610, the sealing structure 600 also seals the outside of the connection between the door 20 and the compartment 10 through the outer sealing section 620, which protects the connecting part 610 and enhances the sealing effect.

[0102] refer to Figure 8 The outer sealing section 620 is also equipped with reflective strips 601. Each reflective strip 601 surrounds the perimeter of the door body 20, which helps to improve the visibility of the vehicle body. When driving at night, the reflective strips 601 can use their retroreflective properties to allow drivers behind to spot the refrigerated truck earlier, thereby maintaining a safe distance and taking timely braking measures to avoid traffic accidents, thus enhancing safety.

[0103] In some embodiments of the present application, the sealing structure 600 further comprises an inner sealing section 630 and a lower sealing section 640, the inner sealing section 630 is formed on the inner side of the connecting section 610 and extends towards the inner wall of the compartment 10, and the lower sealing section 640 is formed on the outer side of the connecting section 610 and extends towards the outer wall of the door 20.

[0104] Specifically, the outer sealing section 620 gradually bends towards the inner side of the compartment 10 in a direction away from the door 20, so that when it is installed, the free end of the outer sealing section 620 is close to the side plate 13, the top plate 11 or the bottom plate 14.

[0105] Similarly, the free end of the inner sealing section 630 gradually approaches the outer side of the compartment 10, so that in the closed state of the door 20, the inner sealing section 630 also closely adheres to the inner wall of the side plate 13, the top plate 11 and the bottom plate 14, thereby enhancing the sealing effect on the compartment 10.

[0106] The free end of the lower sealing section 640 is inclined towards the outer wall of the door 20, which closely adheres to the outer wall of the door 20, thereby reducing the gap between the door 20 and the connecting section 610 and protecting the connecting section 610.

[0107] In other words, the inner sealing section 630 is used to further seal the inner side of the connection between the door 20 and the compartment 10, the outer sealing section 620 and the lower sealing section 640 are respectively used to improve the sealing effect of the connecting section 610 in the upward and downward directions, and the outer sealing section 620 and the lower sealing section 640 can also protect the connecting section 610, reduce the corrosion and damage of the external environment, and improve the service life of the sealing structure 600.

[0108] In some embodiments of the present application, the material of the sealing structure 600 is rubber, and the connecting section 610, the outer sealing section 620, the inner sealing section 630 and the lower sealing section 640 are integrally formed, and the reflective strip 601 is attached to the sealing structure 600.

[0109] The reflective strip 601 is directly connected and fixed to the sealing structure 600 by means of attachment, which is simple to operate and convenient to replace. The connecting section 610, the outer sealing section 620, the inner sealing section 630 and the lower sealing section 640 are integrally formed, which is convenient for processing and has better sealing and protection performance.

[0110] Reference Figures 10-12 In some embodiments of the present application, in order to reduce the scratches and collisions of the trays, support bases and the like supporting goods on the two inner compartment plates 300, causing the inner compartment plates 300 to deform or even be damaged, the protective structure 500 is arranged on the inner side of the inner compartment plate 300.

[0111] Specifically, the mounting portion 310 is formed at the bottom of the inner compartment plate 300, and the protective structure 500 is detachably connected in the mounting portion 310. The protective structure 500 includes a protective base plate 510 and a protective layer 520 attached to the inner surface of the protective base plate 510. The protective base plate 510 is detachably connected to the inner compartment plate 300.

[0112] In some embodiments of the present application, the mounting portion 310 is a mounting hole formed at the lower side of the inner compartment plate 300 and opening downward. Connection groove portions 511 are formed on the end faces of the protective base plate 510 and the mounting portion 310, and the side wall of the mounting portion 310 is inserted into the corresponding connection groove portion 511.
