Description

Technical Field

[0001] This invention belongs to the field of heavy-duty truck cab insulation. Specifically, this invention relates to a heavy-duty truck cab insulation structure and a heavy-duty truck. Background Technology

[0002] The cab of a heavy-duty truck is the core component of the truck, integrating driving operations, rest, and living functions. Its design directly affects the driver's comfort, safety, and work efficiency. While providing the driver with operating space, it also protects the driver from vibrations, noise, and harsh external weather conditions. China has a vast territory spanning a wide range of latitudes, resulting in significant temperature differences between the north and south. Furthermore, with the rapid increase in exports to cold-region countries and regions in recent years, the insulation performance of the cab has become particularly important for drivers who frequently operate in extremely cold environments.

[0003] Current heavy-duty truck cabs consist of a welded and painted body-in-white assembly including crossbeams, longitudinal beams, pillars, and reinforcing plates, plus interior panels. Traditional interior panels serve only decorative or passenger protection purposes and lack strong insulation properties. Aside from a layer of insulation cotton pasted between the cab floor and the engine to block heat exchange from the engine, there are no other insulation measures. Furthermore, the cab's surfaces in greater contact with the external environment include the windshield, side panels, rear panel, and roof. In cold regions, drivers use air conditioning or independent heaters for auxiliary heating, using fuel combustion in the engine or heater to gradually raise the cab temperature through air heat exchange. However, once the heating source is stopped, the temperature drops rapidly due to heat exchange through the windshield, side panels, rear panel, and roof, resulting in poor insulation and increased fuel consumption and transportation costs.

[0004] Therefore, in order to improve or solve at least one of the above problems, a heavy-duty truck cab insulation structure and heavy-duty truck are provided that can effectively improve the insulation performance of the heavy-duty truck cab, effectively isolate the external extremely cold temperature environment, improve the driving comfort of the driver in the heavy-duty truck cab, and reduce truck fuel consumption and transportation costs. Summary of the Invention

Detailed Implementation

[0024] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0025] Figure 1 This is a schematic diagram of the insulation layer in an embodiment of the present invention.

[0026] like Figure 1 As shown, the heavy-duty truck cab insulation structure provided by the present invention includes an insulation layer 100 pasted inside the cab. The insulation layer 100 can effectively improve the insulation performance of the heavy-duty truck cab, effectively isolate the external extremely cold temperature environment, improve the driving comfort of the driver in the heavy-duty truck cab, reduce truck fuel consumption and transportation costs, and is suitable for heavy-duty truck drivers who often work in extremely cold temperature environments, so as to cope with the rapidly increasing export volume to cold countries and regions.

[0027] like Figure 1 As shown, the insulation layer 100 includes a damping layer 101 and a foam layer 102 disposed on the damping layer 101. The damping layer 101 is made of nitrile rubber (NBR, 76% butadiene and 24% acrylonitrile), and the thickness of the damping layer 101 ranges from 1.8 mm to 2.2 mm, with a density of 1.35 g / cm³. 3 -1.75g / cm 3 Nitrile rubber is a lightweight vibration damping layer. By attaching the damping layer 101 to the surface of the metal sheet metal parts inside the cab, it can isolate and weaken sound wave vibrations transmitted from the outside. Simultaneously, due to the high-density material of the damping layer, it can effectively reduce heat exchange between the cab and the external environment. Attaching the damping layer to the cab roof can also reduce the direct contact between humid air inside the cab and the metal sheet metal parts, effectively preventing condensation from forming on the cold metal sheets and corroding them. Therefore, the attachment of the damping layer 101 can effectively extend the service life of the cab and the insulation layer 100, thus maintaining a good insulation effect in the cab for a long time.

[0028] Foam layer 102 is made of chemically cross-linked polyethylene foam (XPE), a closed-cell foam material made from low-density polyethylene as the main raw material through a chemical cross-linking process. It has many excellent properties such as lightweight, flexibility, temperature resistance, waterproof and airtight properties, environmental protection and safety. Chemically cross-linked polyethylene foam does not contain harmful substances such as formaldehyde and heavy metals, and complies with environmental standards such as RoHS and REACH. It is suitable for use in the enclosed space inside heavy trucks. At the same time, chemically cross-linked polyethylene foam can generally maintain stable performance from -50℃ to 100℃ and can withstand high temperatures of 130℃ for short periods, which is far superior to ordinary foam materials (long-term use temperature ≤60℃). It can be used for sound insulation, heat insulation and shock absorption components in automotive interiors, such as dashboard mats, door linings, trunk mats, seat cushioning layers, etc., to improve the comfort of the vehicle interior.

[0029] A tin foil film layer 103 is provided on the side of the foam layer 102 away from the damping layer 101. The tin foil film layer 103 has a dot matrix of holes. By piercing these holes with a needle, the tin foil film layer 103 and the foam layer 102 cause diffuse reflection of heat upon contact, thus providing additional heat reflection. Through the surface structure of the tin foil film layer 103 and the chemical composition of the foam layer 102, heat radiation from the heavy truck cab is reflected from the surface of the tin foil film layer 103, reducing the heat absorption of the insulation layer 100. The physical properties of the tin foil film layer 103 and the chemical composition of the foam layer 102 effectively improve the heat reflection effect, reduce the heat absorbed by the insulation layer 100, and further improve the heat insulation performance of the insulation layer 100. It can effectively isolate the external extremely cold temperature environment, which is conducive to improving the driving comfort of the driver in the cab of the heavy truck, and to reducing the truck's fuel consumption and transportation costs. It is suitable for heavy truck drivers who often work in extremely cold temperature environments, so as to cope with the rapidly increasing export volume to cold countries and regions.

[0030] Figure 2 This is a schematic diagram showing the position of the insulation layer attached to the cab roof in an embodiment of the present invention.

[0031] like Figure 2As shown, the insulation layer 100 is installed on the cab roof. The cab roof is mainly divided into three parts: the front panel 1, the middle panel 2, and the rear panel 3. The front panel 1 overlaps between the front roof beam assembly 4, the left roof beam assembly 5, and the right roof beam assembly 6. The insulation layer 100 is bonded to the front panel 1, except for the connecting edges. The middle panel 2 directly overlaps between the left roof beam assembly 5 and the right roof beam assembly 6. The insulation layer 100 is bonded to the middle panel 2, except for the connecting edges. The rear panel 3 is divided by the cab roof rear panel support beam 7 into a left cab roof panel 8 and a right cab roof panel 9, which facilitates the bonding of the insulation layer 100. The insulation layer 100 is bonded to both the left cab roof panel 8 and the right cab roof panel 9, thereby improving the insulation performance of the heavy truck cab roof. This effectively isolates the cab from extremely cold external temperatures, which is beneficial to improving the driving comfort of the driver in the heavy truck cab, reducing truck fuel consumption and transportation costs. It is suitable for heavy truck drivers who frequently work in extremely cold environments, in order to cope with the rapidly increasing export volume to cold-region countries and regions.

[0032] Figure 3 This is a schematic diagram showing the position of the insulation layer attached to the left side panel of the cab in an embodiment of the present invention;

[0033] like Figure 3 As shown, the insulation layer is installed on the left and right side panels of the cab. Taking the left side panel as an example, the left side panel consists of the cab panel top cover 10 and the lower structure. The lower structure is divided into four parts by the left door inner panel window sill reinforcement plate 11 and the cab B-pillar 12, namely the panel blind window 13, the door panel 14, the toolbox fixing plate 15, and the driver's side glass. The cab panel top cover 10 is an uneven sheet metal part with a large tangential curvature. The insulation layer 100 is pasted to cover the entire cab panel top cover 10. The area of ​​the panel blind window 13 is very flat. All blank areas are covered with insulation layer 100; the door panel 14 has a double-layer structure, and insulation layer 100 needs to be pasted in the interlayer of the door panel 14; insulation layer 100 needs to be pasted on the toolbox fixing plate 15 around the toolbox door, and the insulation layer 100 is set around the toolbox fixing plate 15. In this way, the insulation performance of the heavy truck cab roof is improved, which can effectively isolate the external extremely cold temperature environment, which is conducive to improving the driving comfort of the driver in the heavy truck cab, and is conducive to reducing truck fuel consumption and transportation costs. It is suitable for heavy truck drivers who often work in extremely cold temperature environments, so as to cope with the rapidly increasing export volume to cold countries and regions.

[0034] Figure 4 This is a schematic diagram showing the position of the insulation layer attached to the rear panel of the cab in an embodiment of the present invention;

[0035] like Figure 4 As shown, the insulation layer 100 is installed on the rear panel of the cab, located on the rear panel of the cab rear roof, the rear blind window of the cab, the left side of the upper body of the rear panel, and the right side of the upper body of the rear panel.

[0036] The rear panel of the cab is divided into three sections: the lower left reinforcing beam 15, the lower right reinforcing beam 16, the upper crossbeam 17, the right middle longitudinal beam 18, and the left middle longitudinal beam 19. These sections comprise the rear panel 20 of the cab rear roof, the rear blind window 21, the left side 22 of the upper rear body, and the right side 23 of the upper rear body. The rear panel 20 is further divided into three areas by the lower left and lower right reinforcing beams 15 and 16, each covered with an insulation layer 100. The area of ​​the rear blind window 21 is very flat, with the insulation layer 100 directly applied to the blank areas. The upper body left side 22 and the rear upper body right side 23 are uneven sheet metal parts, but the overall tangential curvature is large. Therefore, the insulation layer 100 needs to be pasted onto the rear upper body left side 22 and rear upper body right side 23 according to the shape. In this way, the insulation performance of the heavy truck cab roof can be improved, which can effectively isolate the external extremely cold temperature environment, which is conducive to improving the driving comfort of the driver in the heavy truck cab, and is conducive to reducing truck fuel consumption and transportation costs. It is suitable for heavy truck drivers who often work in extremely cold temperature environments, so as to cope with the rapidly increasing export volume to cold countries and regions.

[0037] The present invention also provides a heavy-duty truck including the above-mentioned heavy-duty truck cab insulation structure, which is suitable for heavy-duty truck drivers who often work in extremely cold temperature environments, in order to cope with the rapidly increasing export volume to cold-region countries and regions.

[0038] Figure 5 This is a comparison chart of temperature difference test data between the driver's cab with and without the insulation layer pasted, according to an embodiment of the present invention.

[0039] like Figure 5 As shown, a comparative test was conducted in a cold-region outdoor environment on vehicles with and without the insulation structure for heavy-duty truck cabs provided by this invention. The test was performed using an infrared thermal imager. The test method was as follows: with an outdoor temperature of -5℃, the cab temperature was heated to 15℃ by an independent heater, then all heating sources were turned off. After the cab was left to stand for 20 minutes, the temperature values ​​at four points in the cab were measured again. The test results are shown below. Figure 5 As shown.

[0040] The left column shows the test results of a traditional heavy-duty truck cab, while the right column shows the test results of a heavy-duty truck cab after the installation of the insulation structure provided by this invention. The effects of the right side panel, left side panel, and rear panel of the cab are particularly noticeable, with a temperature difference of 2-3℃ and a temperature drop rate increase of 9%-16%. Therefore, the insulation structure provided by this invention enables the heavy-duty truck cab to have perfect heat insulation performance. At the same time, it prevents hot air from condensing on cold metal plates and corroding the sheet metal parts. In addition, in summer, due to the high temperature insulation effect of the insulation material, the cab also has a good insulation effect after the air conditioning is turned on, which helps to reduce truck fuel consumption and transportation costs.

[0041] The role and effect of the embodiments

[0042] The heavy-duty truck cab insulation structure provided by this invention includes an insulation layer 100 adhered inside the cab.

Obviously, the specific implementation of the present invention is not limited to the above-described manner.
