[0052] It should be noted that the "at..." in the embodiment of the present application can be the instant when a certain situation occurs, or it can be a period of time after a certain situation occurs, and the embodiment of the present application does not specifically limit this. In addition, the body assembly structure with heat preservation performance provided in the embodiment of the present application is only used as an example, and the body assembly structure with heat preservation performance can also include more or less content.

[0053] In order to clearly describe the technical solutions of the embodiments of the present application, some terms and technologies involved in the embodiments of the present application are briefly introduced below:

[0054] Noise, Vibration, and Harshness (NVH) performance: refers to the noise, vibration, and harshness characteristics of a vehicle, and is an important indicator for measuring vehicle comfort and driving experience. It focuses on the noise level and vibration conditions inside and outside the vehicle and the impact of these factors on the comfort of the driver and passengers. Good NVH performance can improve the driving and riding experience and reduce fatigue that may be caused by long-term driving.

[0055] Foamable materials: refers to materials that can generate bubbles inside the material through physical or chemical methods to form a porous structure. Foamable materials have the characteristics of light weight, heat insulation, sound insulation, cushioning and energy absorption. Common foamable materials include but are not limited to polyurethane (PU), polyethylene (PE) and ethylene-vinyl acetate copolymer (EVA).

[0056] Improving the thermal insulation performance of the vehicle body is crucial to the riding comfort of the drivers and passengers. As people's requirements for vehicle riding comfort and vehicle energy efficiency continue to increase, improving the thermal insulation performance of the vehicle body is becoming more and more important in vehicle design.

[0057] At present, the common technical means is to install laminated glass in the car body to reduce the overall thermal conductivity of the vehicle, thereby improving the vehicle's thermal insulation performance to a certain extent. However, the thermal insulation effect of this method has limitations and often cannot meet people's demand for higher thermal insulation performance of vehicles.

[0058] Based on this, the embodiment of the present application proposes a body assembly structure with thermal insulation performance, a manufacturing method and a vehicle, which can be used in the field of heavy-duty commercial vehicle design technology, aiming to solve the above technical problems of the prior art and overcome the limitations of the prior art. By adding a thermal insulation layer filled with a material with low thermal conductivity and good thermal insulation performance to the key parts of the body such as the left side of the body, the right side of the body and the rear side of the body, the transfer of heat inside and outside the body is effectively blocked, and the heat loss of the vehicle is reduced, thereby improving the overall thermal insulation performance of the vehicle, thereby improving the riding comfort of the driver and passengers and the energy efficiency of the vehicle.

[0059] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0060] Figure 1 A schematic diagram of a vehicle body assembly structure with heat preservation performance provided in an embodiment of the present application. Figure 1 As shown, the vehicle body assembly structure with heat preservation performance includes: a front body wall 10, a left side body wall 20, a right side body wall 30, a vehicle body floor 40, a vehicle body roof 50 and a rear body wall 60 which are welded together. The vehicle body of a heavy-duty commercial vehicle can be formed by the six assembly structures of the front body wall 10, the left side body wall 20, the right side body wall 30, the vehicle body floor 40, the vehicle body roof 50 and the rear body wall 60.

The filling material 70 poured between the right side outer panel 310 and the right side inner panel 320 can improve the thermal insulation performance of the right side of the vehicle body.

[0063] Figure 4 This is a schematic diagram of the structure of the rear body provided in the embodiment of the present application. Figure 4 As shown, the rear enclosure of the vehicle body includes: a rear enclosure outer panel 410 and a rear enclosure inner panel 420 welded together, and a filling material 70 poured between the rear enclosure outer panel 410 and the rear enclosure inner panel 420. The filling material 70 poured between the rear enclosure outer panel 410 and the rear enclosure inner panel 420 can improve the thermal insulation performance of the rear enclosure of the vehicle body.

[0064] In addition, the left side outer panel 210, the left side inner panel 220, the right side outer panel 310, the right side inner panel 320, the rear side outer panel 410, the rear side inner panel 420, the body floor 40, the body roof 50 and the body rear side panel 60 are all sheet metal stamping parts, not prefabricated composite plates. The thermal insulation performance of the vehicle body can be improved by respectively pouring a filling material with low thermal conductivity and good thermal insulation performance (such as a foamable material such as a water-based polyurethane material) between the left side outer panel 210 and the left side inner panel 220, between the right side outer panel 310 and the right side inner panel 320, and between the rear side outer panel 410 and the rear side inner panel 420, which are stamped and welded together.

[0065] The present embodiment provides a body assembly structure with thermal insulation performance, comprising: a front body panel, a left side panel, a right side panel, a body floor, a body roof and a rear body panel welded together; the left side panel of the body comprises: a left side panel outer panel and a left side panel inner panel welded together, and a filling material poured between the left side panel outer panel and the left side panel inner panel; the right side panel of the body comprises: a right side panel outer panel and a right side panel inner panel welded together, and a filling material poured between the right side panel outer panel and the right side panel inner panel; the rear body panel comprises: a rear panel outer panel and a rear panel inner panel welded together, and a filling material poured between the rear panel outer panel and the rear panel inner panel; the left side panel outer panel, the left side panel inner panel, the right side panel outer panel, the right side panel inner panel, the rear panel outer panel, the rear panel inner panel, the body floor, the body roof and the rear body panel are all sheet metal stamping parts.

[0066] The following technical effects are achieved: the body of a heavy-duty commercial truck can be formed by the six assembly structures of the front body, the left side body, the right side body, the body floor, the body roof and the rear body; the thermal insulation performance of the left side body can be improved by the filling material poured between the left side body outer panel and the left side body inner panel; the thermal insulation performance of the right side body can be improved by the filling material poured between the right side body outer panel and the right side body inner panel; the thermal insulation performance of the rear body can be improved by the filling material poured between the rear side body outer panel and the rear side body inner panel; the thermal insulation performance of the left side body can be improved by the filling material poured between the stamping and welding of the left side body Filling materials with low thermal conductivity and good thermal insulation properties are poured between the outer panel and the left side enclosure inner panel, between the right side enclosure outer panel and the right side enclosure inner panel, and between the rear enclosure outer panel and the rear enclosure inner panel, respectively. This can effectively block the transfer of heat inside and outside the vehicle body, reduce heat loss in the vehicle, and improve the overall thermal insulation performance of the vehicle body, thereby improving the riding comfort of the driver and passengers, and further reducing the energy consumed by frequent temperature adjustment of the vehicle air conditioner; and by filling the gaps inside the vehicle body cavity, the sealing performance of the vehicle body is improved, the vibration noise of the vehicle is reduced, thereby improving the NVH performance of the vehicle.

[0067] Figure 5 A schematic diagram of the structure of the left side inner panel provided in the embodiment of the present application is shown in FIG. Figure 5 As shown, a pouring hole 80 is provided on the left side inner panel 220 .

[0068] Figure 6 A schematic diagram of the structure of the right side inner plate provided in the embodiment of the present application is shown in FIG. Figure 6 As shown, a pouring hole 80 is provided on the right side inner panel 320 .

[0069] Figure 7 A schematic diagram of the structure of the rear inner panel provided in the embodiment of the present application is shown in FIG. Figure 7 As shown, a pouring hole 80 is provided on the rear inner panel 420 .

[0070] Further, in a possible implementation, the left side outer panel 210, the right side outer panel 310, the rear side outer panel 410, the left side inner panel 220, the right side inner panel 320 and the rear side inner panel 420 are all provided with a pouring hole 80. The diameter of the pouring hole can be set to about 20 mm, such as 15 mm to 25 mm. The filling material 70 is formed by pouring a foamable material through the pouring hole 80.

[0071] Specifically, the foamable material can be poured into the interior of the three major assembly structures, namely the left side panel 20, the right side panel 30 and the rear panel 40, through the injection holes 80 reserved on the vehicle body. After the foamable material is formed, an insulation layer is formed, so that the vehicle body assembly is transformed from the original double-layer structure to a three-layer structure of an insulation wall, thereby improving the insulation performance of the vehicle body. The injection speed of the foamable material can be further increased by setting injection holes on both the inner and outer panels.

[0072] Further, in a possible embodiment, the injection holes 80 of the left side outer panel 210 and the injection holes 80 of the left side inner panel 220 are not aligned; the injection holes 80 of the right side outer panel 310 and the injection holes 80 of the right side inner panel 320 are not aligned; the injection holes 80 of the rear side outer panel 410 and the injection holes 80 of the rear side inner panel 420 are not aligned. The flow rate of the foaming material can be adjusted by the non-aligned injection holes 80 between the inner and outer panels. For example, if the space between the inner panel and the outer panel is larger in some areas and smaller in other areas, the injection amount of the foaming material in each area can be more accurately controlled by the non-aligned injection holes 80, thereby ensuring the uniformity and stability of the entire vehicle body structure. In addition, the non-aligned injection holes 80 on the inner and outer panels can ensure the stability of the structures of the left side panel 20, the right side panel 30 and the rear panel 40 of the vehicle body. In particular, during the welding process of the inner and outer panels, due to various reasons (such as thermal expansion and contraction of the material, processing errors, etc.), the plate structure may undergo slight deformation. In this case, the misaligned injection holes 80 can accommodate such deformation to a certain extent, thereby reducing the impact on the structural integrity and stability of the plate. In addition, the misaligned injection holes on the inner and outer panels can prevent other body parts or structures from being adjacent to or intersecting with the injection holes during the injection process, thereby affecting the injection effect, thereby ensuring that the injection material flows smoothly while avoiding unnecessary damage to adjacent parts.

[0073] Furthermore, in a possible embodiment, one or more injection holes are evenly arranged on the first diagonal of the left side outer panel, and one or more injection holes are evenly arranged on the second diagonal of the left side inner panel, and the first diagonal and the second diagonal are at an angle; one or more injection holes are evenly arranged on the third diagonal of the right side outer panel, and one or more injection holes are evenly arranged on the fourth diagonal of the right side inner panel, and the third diagonal and the fourth diagonal are at an angle; one or more injection holes are evenly arranged on the fifth diagonal of the rear side outer panel, and one or more injection holes are evenly arranged on the sixth diagonal of the rear side inner panel, and the fifth diagonal and the sixth diagonal are at an angle. By evenly arranging one or more injection holes on the diagonals of the inner panel and the outer panel, and making the diagonals of the inner panel and the outer panel at an angle rather than being arranged in parallel, the injection speed of the foamable material can be further increased.

[0074] In a possible implementation, a heating pipe is injection-molded into the filling material for heating by liquid circulation.

[0075] Specifically, in order to further improve the thermal insulation performance of the vehicle body assembly structure, a heating pipe can be pre-set in the filling material, and the vehicle body assembly structure can be further heated through the heating pipe. The heating pipe can be provided with a self-heating material or a heatable liquid (such as water, lubricating oil or heat transfer oil, etc.).

[0076] In a possible implementation, the heating pipe is connected to the vehicle engine for heating the coolant by means of the coolant heated during the operation of the vehicle.

[0077] Specifically, when the engine is running, the coolant circulates inside the engine, absorbing and taking away the heat generated by the engine. In the embodiment of the present application, the heating pipe can be connected to the cooling system of the engine to guide the coolant heated by the engine cooling system to the left side body 20, the right side body 30 and the rear body 60 that need to be heated, thereby using the heat generated by the engine to heat the coolant, and then heating the body through the coolant, which not only realizes the recycling of the engine heat, but also further improves the thermal insulation performance of the body assembly structure.

[0078] In a possible implementation manner, an insulating layer is encapsulated around the periphery of the heating pipe, and the insulating layer is used to isolate and protect the heating pipe and the filling material.

[0079] Specifically, in order to isolate and protect the heating pipe and the filling material and prevent the heating pipe from corroding and leaking, an isolation layer can be further provided around the heating pipe. The isolation layer can be made of a polymer composite material with corrosion resistance and high mechanical strength, or made of materials such as polyethylene film, without specific restrictions. By encapsulating the isolation layer around the heating pipe, the heating pipe and the filling material can be further isolated and protected, thereby improving the stability and safety of the insulation layer in the vehicle body assembly structure.

[0080] The present application also provides a method for manufacturing a body assembly structure with heat preservation performance, the method comprising: first, stamping out sheet metal stamping parts of a body front wall, a body roof, a body floor, a left side wall outer panel, a left side wall inner panel, a right side wall outer panel, a right side wall inner panel, a rear wall outer panel and a rear wall inner panel respectively; then, welding the left side wall outer panel and the left side wall inner panel together to form a left side wall of the body; and welding the right side wall outer panel and the right side wall inner panel together to form a right side wall of the body; and welding the rear wall outer panel and the rear wall inner panel together to form a rear wall of the body; then, welding the body front wall, the body roof, the body floor, the left side wall of the body, the right side wall of the body and the rear wall of the body together to form an overall frame of the body assembly structure; finally, through the injection holes, injecting filling materials into the gaps between the left side wall outer panel and the left side wall inner panel, the gaps between the right side wall outer panel and the right side wall inner panel, and the gaps between the rear wall outer panel and the rear wall inner panel, respectively, so as to further form a body assembly structure with heat preservation performance.

[0081] Furthermore, in a possible embodiment, the left side outer panel and the left side inner panel are welded together to form the left side panel of the vehicle body, including: after installing a heating pipe and an insulating layer on the left side panel outer panel and / or the left side panel inner panel, the left side panel outer panel and the left side panel inner panel are welded together to form the left side panel of the vehicle body.

[0082] The right side outer panel and the right side inner panel are welded together to form the right side panel of the vehicle body, including: after installing a heating pipe and an insulating layer on the right side outer panel and / or the right side inner panel, the right side outer panel and the right side inner panel are welded together to form the right side panel of the vehicle body.

[0083] The rear enclosure outer panel and the rear enclosure inner panel are welded together to form the rear enclosure of the vehicle body, including: after installing a heating pipe and an insulating layer on the rear enclosure outer panel and / or the rear enclosure inner panel, the rear enclosure outer panel and the rear enclosure inner panel are welded together to form the rear enclosure of the vehicle body.

[0084] That is to say, by installing heating pipes and insulation layers between the left side outer panel and the left side inner panel, between the right side outer panel and the right side inner panel, and between the rear side outer panel and the rear side inner panel, the thermal insulation performance of the vehicle body assembly structure can be further improved.
