[0026] In daily life, frozen or fresh goods need to be transported in refrigerated trucks to prevent them from spoiling. The temperature inside refrigerated trucks is relatively low, for example, below zero degrees Celsius. The thermal insulation compartment 100 of conventional refrigerated trucks is typically made of four layers of fiberglass, wood, extruded board 2, and fiberglass, which are glued together. This involves first spraying glue with a glue sprayer and then hot pressing with a hot press to glue the layers of composite board together. This not only results in a complex manufacturing process and high costs, but also poor environmental performance of the glue. Furthermore, the sub-zero temperature inside the refrigerated truck may cause the fiberglass of the thermal insulation compartment 100 to bulge, affecting the service life and aesthetics of the compartment.

[0027] like Figure 1 and Figure 2As shown, based on the above technical problems, this embodiment provides a refrigerated truck, which includes an insulated compartment 100, which is composed of a frame and a compartment composite panel 10. The compartment composite panel 10 includes an outer aluminum plate 1, an extruded panel 2 (full name: extruded polystyrene foam panel), a fireproof cloth 3, and an inner honeycomb aluminum panel 4, which are stacked in sequence. The outer aluminum plate 1 and the extruded panel 2 are fixedly connected by a plurality of first rivets 5, and the inner honeycomb aluminum panel 4, the fireproof cloth 3, and the extruded panel 2 are fixedly connected by a plurality of second rivets (not shown in the figure). The outer aluminum plate 1 forms the outer layer of the insulated compartment 100, and the inner honeycomb aluminum plate 4 forms the inner layer of the insulated compartment 100. The outer aluminum plate 1 and the inner honeycomb aluminum plate 4 are lightweight, which helps reduce the weight of the insulated compartment 100 and improve the load capacity of the refrigerated truck. Furthermore, both the outer aluminum plate 1 and the inner honeycomb aluminum plate 4 have advantages such as strong corrosion resistance, good fire resistance, lightness, ease of processing, environmental protection, thermal insulation and sound insulation, high strength, durability, aesthetics, and easy cleaning. Preferably, the outer aluminum plate 1 is an aviation aluminum alloy plate, which has high hardness and good drilling performance, facilitating the riveting of the first rivet 5. Under the above structure, by arranging the outer aluminum plate 1, the extruded plate 2, the fireproof cloth 3 and the inner honeycomb aluminum plate 4, the fiberglass in the traditional car composite panel 10 is replaced, and the temperature resistance is better, especially at temperatures below zero degrees Celsius, it is not easy to bulge and deform, etc., thereby ensuring the reliability and aesthetics of the car composite panel 10, that is, the service life of the car composite panel 10 is longer; and the fireproof cloth 3 further enhances the fireproof effect, ensuring the safety of use of the car composite panel 10, wherein the fireproof cloth 3 can be selected from one of silicone rubber coated glass fiber cloth, basalt fiber fireproof cloth 3, acrylic cotton fiber fireproof cloth 3, Nomex fireproof cloth 3, SM fireproof cloth 3, blue glass fiber fireproof cloth 3, aluminum foil fireproof cloth 3, etc.; at the same time, the outer aluminum plate 1, the extruded plate 2, the fireproof cloth 3 and the inner honeycomb aluminum plate 4 are connected and fixed by the first rivet 5 and the second rivet. Compared with the traditional technology of using glue to bond, it is not only energy-saving and environmentally friendly, but also has low cost, easy processing and manufacturing, and high production efficiency. That is, the heat-insulating compartment 100 provided in this embodiment has good heat-insulating performance, light weight, high overall structural strength, and good corrosion resistance and temperature resistance.

[0028] As can be understood, a metal tube framework is nested outside the extruded panels 2. Several first rivets 5 are riveted to the outer aluminum panel 1 and the metal tube framework, while several second rivets are riveted to the inner honeycomb aluminum panel 4, the fireproofing fabric 3, and the metal tube framework. The metal tube framework provides support and shaping for the extruded panels 2, increasing the overall structural strength of the vehicle body composite panel 10. It also provides riveting surfaces for the first and second rivets 5, ensuring a stable and reliable connection between the first and second rivets, thereby improving the overall structural stability of the vehicle body composite panel 10.

[0029] Preferably, the surface of the metal tube frame is plated with a zinc layer to increase weather resistance and corrosion resistance, thereby extending the service life of the composite vehicle panel 10 of the vehicle compartment.

[0030] In this embodiment, the thickness of the outer aluminum plate 1 is 1.5mm-2.5mm, for example, the thickness of the outer aluminum plate is 1.5mm, 1.8mm, 2mm, 2.3mm, 2.5mm, etc., which is set according to actual needs; the thickness of the extruded board 2 is 70mm-80mm, for example, the thickness of the extruded board 2 is 70mm, 72mm, 75mm, 77mm, 80mm, which is set according to actual needs; the thickness of the fireproof cloth 3 is 0.5mm-1.5mm, for example, the thickness of the fireproof cloth 3 is 0.5mm, 1.8mm, 1mm, 1.3mm, 1.5mm, etc., which is set according to actual needs; the thickness of the inner honeycomb panel is 2.5mm-3.5mm, for example, the thickness of the inner honeycomb panel is 2.5mm, 2.7mm, 3mm, 3.3mm, 3.5mm, etc., which is set according to actual needs. It should be noted that the thickness of the extruded board 2 here can be the thickness of the extruded board 2 itself or the thickness of the extruded board 2 plus the metal tube skeleton embedded outside.

[0031] Specifically, the metal tube skeleton includes a first skeleton surface and a second skeleton surface located on both sides of the extruded plate 2. The first skeleton surface includes a plurality of first rectangular metal tubes spaced apart along the length direction of the car body composite panel 10, and each first rivet 5 is riveted to the outer aluminum plate 1 and a first rectangular metal tube. The second skeleton surface includes a plurality of second rectangular metal tubes spaced apart along the length direction of the car body composite panel 10, and each second rivet is riveted to the inner honeycomb aluminum plate 4, the fireproof cloth 3 and a second rectangular metal tube. The length direction of the car body composite panel 10 can be the length direction or the width direction of the refrigerated truck, which is not limited here. The first rectangular metal tube and the second rectangular metal tube are riveted together respectively by the first rivet 5 and the second rivet, that is, the plurality of first rivets 5 on one side are evenly arranged in horizontal and vertical rows, and the plurality of second rivets on the other side are also evenly arranged in horizontal and vertical rows, so that the car body composite panel 10 is not only structurally stable and reliable, but also has a neat and beautiful appearance.

[0032] The composite vehicle compartment panel 10 provided in this embodiment has excellent structural stability, is not easily deformed or bulged, is environmentally friendly, has low manufacturing costs, high manufacturing efficiency, a long service life, and is safe to use. The refrigerated truck provided in this embodiment, by adopting the composite vehicle compartment panel 10, has the advantages of the composite vehicle compartment panel 10 described above.
