Description

Technical Field

[0001] The utility model relates to the technical field of cold chain logistics, and in particular to a compartment plate frame of a refrigerated truck, a compartment plate comprising the compartment plate frame, and a refrigerated truck comprising the compartment plate. Background Art

[0002] The compartment panel is the enclosure structure of the refrigerated truck compartment. It isolates the cargo from the outside environment, provides a relatively closed space for the cargo, and prevents the cargo from being polluted and eroded by external dust, debris, rain, etc. The compartment panel has a heat-insulating structure to limit the heat exchange between the inside and outside of the compartment. The compartment panel is also airtight to prevent external moisture and pollutants from entering, and can also reduce the heat exchange between the inside and outside of the compartment. At the same time, the compartment panel can bear the weight of the cargo and evenly transfer the gravity of the cargo to the subframe of the refrigerated truck.

[0003] The car body is usually composed of several parts, such as outer skin, car body frame, insulation board, inner skin, etc. Among these components, the car body frame plays a vital role and has a decisive influence on the strength of the entire car body.

[0004] At present, refrigerated trucks usually use square wood frames, add square wood reinforcement beams on the frames to make the body frame, and embed metal pre-embedded parts inside the square wood. In the actual use of refrigerated trucks, when the load inside the car and various forces from the road surface are applied to the body, these loads are ultimately borne by the frame, insulation board and reinforcement beams.

[0005] However, it should be noted that the metal embedded parts inside the square timber cannot enhance the bending and torsion resistance of the square timber reinforcement beam. The metal embedded parts are only for connection with the subframe. As a result, the overall strength of the compartment board is low, which not only affects the performance and safety of the refrigerated truck, but also brings certain risks and challenges to the transportation of goods. Summary of the invention

[0006] The utility model aims to provide a compartment plate frame of a refrigerated truck, which has higher anti-bending and torsion performance.

[0007] Another object of the utility model is to provide a car body comprising the car body frame, which has a higher bending and torsion resistance.

[0008] Another object of the present invention is to provide a refrigerated truck including the above-mentioned compartment plate, which includes a compartment plate with high bending and torsion resistance and has good performance in use and high safety.

[0009] The panel frame of the refrigerated truck provided by the present utility model comprises two side beams, several reinforcing beams and several strengthening members. The two side beams form two opposite sides of a rectangular structure. Each reinforcing beam is vertically connected between the two side beams, and the several reinforcing beams are arranged along the length direction of the side beams, wherein the two reinforcing beams located at the head and the tail form the other two opposite sides of the rectangular structure. Each strengthening member is connected to a reinforcing beam or a side beam, and can support the reinforcing beam or the side beam along the width direction and the thickness direction of the reinforcing beam or the side beam to which it is connected, so as to limit the bending deformation of the reinforcing beam or the side beam.

[0010] By arranging strengthening members on the reinforcing beam and / or the side beam, the reinforcing beam and / or the side beam are strengthened along their respective width directions and thickness directions, thereby improving the bending and torsion resistance of the panel frame.

[0011] In another schematic embodiment of the panel frame of the refrigerated truck, each of the two side beams is connected with a strengthening member having the same length as it. At least two of the reinforcing beams are each connected with a strengthening member having the same length as it. These strengthening members with the same length are welded to form a rectangular frame. Thereby, the panel frame can be further strengthened to have better overall performance.

[0012] In yet another schematic embodiment of the panel frame of the refrigerated truck, the strengthening member is an integral structure formed by bending a plate along a broken line parallel to its length direction. The strengthening member comprises an embedding part and a supporting part perpendicular to the embedding part. The reinforcing beam or the side beam connected to the strengthening member is provided with at least one slot extending along their respective width directions. The embedding part can be embedded into the slot along the width direction of the reinforcing beam or the side beam and is used for connecting the sub-frame. The supporting part can be attached to the reinforcing beam or the side beam along the width direction of the reinforcing beam or the side beam. This structure is simple, convenient for disassembly and assembly, and can effectively strengthen the reinforcing beam or the side beam.

[0013] In another schematic embodiment of the panel frame of the refrigerated truck, the strengthening member further comprises a first bending part. The first bending part is connected to the supporting part and is parallel to the embedding part. The embedding part and the first bending part are arranged on the same side of the supporting part. The first bending part can be attached to the reinforcing beam or the side beam and is provided with several connecting holes. The reinforcing beam or the side beam connected to the strengthening member is formed with several protruding connecting parts. Each connecting part can be inserted into a connecting hole to connect the strengthening member. Thereby, it is convenient for the connection between the strengthening member and the reinforcing beam or the side beam, and this structure is simple, can reduce the weight and avoid the dislocation between the strengthening member and the reinforcing beam or the side beam. In addition, the bending part can also share a part of the load to further strengthen the reinforcing beam or the side beam.

[0014] In another exemplary embodiment of the panel frame of the refrigerated truck, the reinforcing member further includes a second bent portion. The second bent portion is connected to the support portion and is parallel to the embedded portion. The embedded portion and the second bent portion are disposed on opposite sides of the support portion. This facilitates the installation of the reinforcing member to the reinforcing beam or the side beam.

[0015] In another exemplary embodiment of the panel frame of the refrigerated truck, two tenons are protrudingly provided at both ends of each reinforcing beam along its length direction. A plurality of pairs of opposing mortises are formed on the opposing end faces of the two side beams. The two tenons of each reinforcing beam can be respectively inserted into a pair of mortises to achieve connection. Through the mortise and tenon structure, it is convenient to connect the reinforcing beam and the side beam into a rectangular structure, which has a simple structure and is easy to install.

[0016] The present invention also provides a panel of a refrigerated truck, including the above-mentioned panel frame. By providing the above-mentioned panel frame, the bending and torsion resistance performance of the panel can be effectively improved, which is beneficial to enhancing the overall performance of the panel.

[0051] For a clearer understanding of the technical features, objectives, and effects of the utility model, the specific implementation manners of the utility model are now described with reference to the accompanying drawings, where the same reference numerals denote the same parts in each figure.

[0052] In this document, "schematic" means "serving as an example, instance, or illustration", and any illustration or implementation manner described as "schematic" in this document should not be construed as a more preferred or more advantageous technical solution.

[0053] To simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product.

[0054] Figure 1 It is a schematic structural diagram of a schematic implementation manner of the compartment board skeleton of a refrigerated truck. Refer to Figure 1 , in the schematic implementation manner, the compartment board skeleton 100 of the refrigerated truck is a rectangular structure. The compartment board skeleton 100 includes two side beams 10, seven reinforcing beams 20 ( Figure 1 only one of which is marked in ), and two reinforcing members 30 (each of the two reinforcing members 30 covers one reinforcing beam 20). The two side beams 10 form two opposite sides of the rectangular structure. The side beams 10 and the reinforcing beams 20 are, for example, square timbers, but are not limited thereto. Each reinforcing beam 20 is vertically connected between the two side beams 10, and the seven reinforcing beams 20 are arranged along the length direction of the side beams 10, and the two reinforcing beams 20 at the head and tail (i.e., the two reinforcing beams 20 each covered by one of the two reinforcing members 30) form the other two opposite sides of the rectangular structure. Two reinforcing members 30 having the same length as the reinforcing beams 20 are respectively connected to the two reinforcing beams 20 at the head and tail. In other schematic implementation manners, the number of the reinforcing beams 20 and the reinforcing members 30 can be adjusted according to the actual load conditions and transportation conditions. In addition, those skilled in the art can also flexibly set reinforcing members 30 with different lengths on the side beams 10 and the reinforcing beams 20 according to the actual load conditions, and the longest reinforcing member 30 has the same length as the side beam 10 or the reinforcing beam 20 to which it is connected.

[0055] Each reinforcing member 30 can support the reinforcing beam 20 along the width direction and the thickness direction of the reinforcing beam 20 to which it is connected, so as to limit the bending deformation of the reinforcing beam 20. In other schematic implementation manners, if a reinforcing member 30 is connected to the side beam 10, then the reinforcing member 30 can support the side beam 10 along the width direction and the thickness direction of the side beam 10 to which it is connected, so as to limit the bending deformation of the side beam 10.

[0056] By providing reinforcing members on the reinforcing beam or the side beam, the reinforcing beam or the side beam is strengthened along its respective width direction and thickness direction, so that the compartment board skeleton has a high bending and torsion resistance performance.Figure 1 The shown side panel framework only sets strengthening members 30 of the same length on the first and last two reinforcing beams 20. It can be used as the side panel framework for the front, rear, left, and right sides of the refrigerated carriage body and the top side panel framework, and can also be used as the side panel framework for the bottom of the low-load refrigerated carriage body.

[0057] For a refrigerated truck with a large actual load, as the side panel framework for the bottom of the refrigerated truck, strengthening members 30 can also be added on at least one reinforcing beam 20 located between the first and last two reinforcing beams 20. Figure 2 It is a structural schematic diagram of another schematic implementation manner of the side panel framework of the refrigerated truck. In the schematic implementation manner, refer to Figure 2 , this side panel framework 100 can be used as the side panel framework for the bottom of the refrigerated truck, for example. As Figure 2 shown, on the basis of the side panel framework shown in Figure 1 , among the seven reinforcing beams 20, four of the five middle reinforcing beams 20 are respectively connected with a strengthening member 30 shorter than the reinforcing beam 20 in the middle ( Figure 2 only one of them is marked in the figure), so as to share the load applied to these four reinforcing beams 20, thus playing a strengthening role. In other schematic implementation manners, the number of the reinforcing beams 20 and the strengthening members 30 arranged on them can be adjusted according to the actual load conditions and transportation conditions. The length of the strengthening member 30 can also be adjusted according to the actual application situation, and the longest can be equal to the length of the reinforcing beam 20.

[0058] In other schematic implementation manners, to further improve the bending and torsional resistance performance of the side panel framework 100 at the bottom of the refrigerated truck, on the basis of the side panel framework 100 shown in Figure 1 or Figure 2 , a strengthening member 30 of the same length can also be respectively arranged on each side beam 10, and then the four strengthening members 30 respectively connecting two side beams 10 and two reinforcing beams 20 at the first and last are welded to form a rectangular frame composed of the strengthening members 30. By this means, the side panel framework can be further strengthened, so that it can bear various loads such as tension, shear, bending, and torsion when loaded, has higher strength, stiffness, and stability, and better bending and torsional resistance performance.

[0059] Furthermore, on the basis of the four strengthening members 30 respectively connecting two side beams 10 and two reinforcing beams 20 at the first and last by welding, a strengthening member 30 of the same length can also be arranged on at least one middle reinforcing beam 20 (that is, the reinforcing beam 20 located between the first and last reinforcing beams 20), and then these strengthening members 30 are also welded to the strengthening members 30 connecting two side beams 10. This way can effectively improve the bending and torsional resistance performance of the side panel framework.

[0060] Next, taking the connection relationship between the strengthening member 30 and the reinforcing beam 20 as an example, the structure of the strengthening member 30 will be described.Figure 3 The Figure 1 cross-sectional view of the reinforced beam and the reinforcement member connecting the reinforced beams is shown. Figure 4 The Figure 1 exploded view of the reinforced beam and the reinforcement member connecting the reinforced beams is shown. In the illustrative embodiment, refer to Figure 3 and Figure 4 , the reinforcement member 30 is an integral structure formed by bending a sheet along a fold line parallel to its length direction, and includes seven embedding portions 31 ( Figure 4 only one of which is marked in Figure 4 ) and a support portion 32 perpendicular to the embedding portion. The reinforced beam 20 is provided with seven slots 21 extending along its width direction W ( Figure 4 only one of which is marked in

[0061] As Figure 3 and Figure 4 shown, in the illustrative embodiment, the reinforcement member 30 further includes a first bending portion 33. The first bending portion 33 is connected to the support portion 32 and parallel to the embedding portion 31. The embedding portion 31 and the first bending portion 33 are arranged on the same side of the support portion 32. The first bending portion 33 can be attached to the reinforced beam 20 and is provided with several connecting holes 331. The reinforced beam 20 is formed with several protruding connecting portions 22. Each connecting portion 22 can be inserted into a connecting hole 331 to connect the reinforcement member 30. This facilitates the connection between the reinforcement member and the reinforced beam, and the structure is simple, which can reduce the weight and avoid misalignment between the reinforcement member and the reinforced beam. In addition, the first bending portion can also share the load parallel to the thickness direction and the load parallel to the width direction, further strengthening the reinforced beam. In other illustrative embodiments, the connection strength between the reinforcement member 30 and the reinforced beam 20 can also be enhanced by means such as adhesives and screw connections.

[0062] The embedding portion 31 is also used to connect the subframe, and the way of connecting the subframe is well-known to those skilled in the art. For example, first, a hole is opened at the bottom of the reinforced beam 20 (i.e., Figure 3 the lower bottom of the reinforced beam 20 in

[0063] In addition, since the reinforcing member 30 is made of aluminum alloy or high-strength steel plate, it has a relatively high thermal conductivity. The embedding portion 31 is embedded in the slot 21, and the height of the first bending portion 33 is set to be lower than the height of the connecting portion 22, for example. This is beneficial to effectively reduce the contact area between other structures and the reinforcing member when laying other structures on the panel framework, is beneficial to form a cold insulation structure, and is conducive to cutting off the transfer of external heat to the inside of the refrigerated compartment through the panel.

[0064] The structure of the reinforcing member 30 of the connecting and reinforcing beam 20 is the same as that of the reinforcing member 30 of the connecting side beam 10, and the strengthening principle is also the same, so it will not be elaborated here.

[0065] Figure 5 Another schematic implementation manner for explaining the reinforcing member. Figure 6 Another schematic implementation manner for explaining the reinforcing member. Figure 5 and Figure 6 shows an exploded view of the reinforcing member and the reinforcing beam connecting it. Figure 5 and Figure 6 The same parts of the reinforcing member 30 shown in Figure 4 and the reinforcing member 30 shown in Figure 5 will not be elaborated. The difference between them is that the reinforcing member 30 shown in Figure 6 does not have the first bending portion 33 and has a second bending portion 34. The second bending portion 34 is connected to the supporting portion 32 and is parallel to the embedding portion 31. The embedding portion 31 and the second bending portion 34 are arranged on different sides of the supporting portion 32. The second bending portion 34 is inserted into or abuts against the heat insulation member filled in the panel framework 100, which will be described later. Figure 6 The reinforcing member 30 shown in Figure 4 does not have the first bending portion 33 or the second bending portion 34. Compared with the reinforcing member 30 shown in Figure 5 and Figure 6 The structure of the reinforcing member 30 shown in

[0066] In the schematic implementation manner, referring to Figure 1 and Figure 4 , two tenons 23 are protrudingly arranged at both ends of each reinforcing beam 20 along its length direction L. A plurality of pairs of opposite mortises are opened on the opposite end faces of the two side beams 10. The two tenons 23 of each reinforcing beam 20 can be respectively inserted into a pair of mortises to achieve connection. To obtain higher connection strength, the mortise and tenon structure can also be combined with woodworking nails or adhesives. Through the mortise and tenon structure, it is convenient to connect the reinforcing beam and the side beam into a rectangular structure, and this structure is simple and convenient to install.

[0067] The present utility model also provides a compartment board for a refrigerated truck. Figure 7 It is a partial cross-sectional view of a schematic embodiment of the compartment board. Refer to Figure 7 , the compartment board sequentially includes an outer skin layer 40, Figure 2 the shown compartment board skeleton 100, a reinforcing layer 50, a cold insulation layer 60, and a heat preservation member 70 filled in the chamber surrounded by the outer skin layer 40, the reinforcing layer 50, and the compartment board skeleton 100. Among them, between the outer skin layer 40 and the compartment board skeleton 100, between the outer skin layer 40 and the heat preservation member 70, between the compartment board skeleton 100 and the reinforcing layer 50, between the heat preservation member 70 and the reinforcing layer 50, and between the reinforcing layer 50 and the cold insulation layer 60 are all connected by adhesives. The outer skin layer 40 faces the outside of the compartment of the refrigerated truck, and the cold insulation layer 60 faces the inside of the compartment of the refrigerated truck. The compartment board skeleton 100 of this schematic embodiment selects Figure 4 the shown reinforcing member 30. The reinforcing layer 50 is, for example, a fiberglass mat reinforced composite material layer. The outer skin layer 40 is, for example, a fiberglass composite material board or a thermoplastic board. In other schematic embodiments, the compartment board skeleton 100 can also be other forms of compartment board skeletons as described above. By providing the above-mentioned compartment board skeleton, the bending and torsional resistance performance of the compartment board can be effectively improved, which is beneficial to enhancing the overall performance of the compartment board.

[0068] Figure 8 It is a partial cross-sectional view of another schematic embodiment of the compartment board. Refer to Figure 8 , the compartment board skeleton 100 selects Figure 5 the shown reinforcing member 30, and the second bending portion 34 of the reinforcing member 30 is inserted into the heat preservation member 70. The heat preservation member 70 is, for example, a polyurethane heat preservation material, which is easy to cut and process. In other schematic embodiments, the second bending portion 34 can also lean on the surface of the heat preservation member 70 in contact with the reinforcing layer 50. An adhesive can be coated between the reinforcing member 30 and the heat preservation member 70 to increase the connection strength. Figure 5 The shown reinforcing member can increase the contact area with the heat preservation member, which is beneficial to enhancing the connection between the two.

[0069] In the schematic embodiment, the cold insulation layer 60 sequentially includes a plywood layer 61 and an inner skin layer 62 along the thickness direction of the compartment board. The plywood layer 61 and the inner skin layer 62 are connected by an adhesive. The inner skin layer 62 is, for example, a fiberglass composite material board or a thermoplastic board.

[0070] In other schematic embodiments, the cold insulation layer 60 is a honeycomb board or a ventilation groove structure. Generally, the honeycomb board is used in the compartment boards on the front, rear, left, and right sides, and the ventilation groove structure, such as an integral aluminum track, is used in the bottom compartment board to realize the cold air circulation and heat dissipation in the compartment.

[0071] When the cold insulation layer includes a plywood layer and an inner skin layer, the manufacturing process of the compartment board includes: first connecting the side beams, reinforcing members, and reinforcing beams to form a compartment board skeleton; then laying the outer skin layer on a tooling, and spraying an adhesive, such as polyurethane structural adhesive; placing the compartment board skeleton above the outer skin layer; placing a heat preservation member in the compartment board skeleton, such as extruded polystyrene foam, polyurethane foam, or polypropylene foam; spraying an adhesive; laying a reinforcing layer; spraying an adhesive; laying plywood; spraying an adhesive and laying the inner skin layer; and pressing the above materials into shape by means of positive pressure or negative pressure pressing.

[0072] When the cold insulation layer is a honeycomb board or a ventilation slot structure, after laying the reinforcing layer through the above process, then lay the honeycomb board or the ventilation slot structure, and press the above materials into shape by means of positive pressure or negative pressure pressing.
