[0020] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only some embodiments of the present application, rather than all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application, its application, or use.

[0021] like Figure 1 As shown, the present embodiment discloses a high-sound insulation and high-heat insulation performance high-speed vehicle driver's cab door leaf, including a door body 1, a first isolation layer 5, a third isolation layer 6, a second isolation layer 7, a first glass 2, and a second glass 3, wherein the door body 1 is provided with two installation areas, namely a first installation area and a second installation area, the first installation area is arranged inside the cavity of the door body 1, the second installation area is arranged in the middle of the door body 1, and the second installation area is surrounded by the first installation area. The first isolation layer 5 is fixed on the side of the first installation area close to the outside of the vehicle, and the third isolation layer 6 is fixed on the side of the first installation area close to the inside of the vehicle. The first isolation layer 5 and the third isolation layer 6 are arranged at intervals, and the second isolation layer is arranged in the cavity of the door panel frame 101, and is interspersed between the first isolation layer 5 and the third isolation layer 6.

[0022] In this embodiment, the two isolation layers are separately arranged in the driver's cab door leaf, which is convenient for installation in the special-shaped curved surface structure of the vehicle head. The first isolation layer 5 is installed close to the inside of the vehicle, the third isolation layer 6 is installed close to the outside of the vehicle, and the second isolation layer 7 is distributed inside the cavity of the door panel frame 101. The three isolation layers greatly improve the sound insulation and heat insulation performance of the door leaf. The two glasses in the second installation area also form a gradient sound insulation effect. The door leaf as a whole effectively blocks the transmission path of noise and heat, achieving high sound insulation and high heat insulation performance.

[0023] The cross-section of the door body 1 facing the outside of the vehicle in this embodiment is curved. The door body 1 includes a door panel frame 101, an inner cover shell 102, an inner skin 103 and an outer skin 104. The door panel frame 101 and the inner cover shell 102 are connected to form the first installation area. The inner skin 103 is attached to the side of the inner cover shell 102 facing the inside of the vehicle, and the outer skin 104 is attached to the side of the door panel frame 101 facing the outside of the vehicle. The skin is usually made of lightweight, high-strength materials, such as stainless steel or composite materials. These materials can ensure that the train can withstand the pressure and impact of the external environment when traveling at high speed, while maintaining the stability and safety of the overall structure.

[0024] In this embodiment, the first isolation layer 5 includes polyester fiber floss 51 and epoxy foam 52. The polyester fiber floss 51 is placed in the first installation area, the epoxy foam 52 covers part of the first installation area, and the polyester fiber floss 51 is located in the epoxy foam 52. During the design operation, the position of the polyester fiber floss 51 can be fixed, and then the epoxy foam 52 can be injected into the first installation area. The epoxy foam 52 firmly wraps the polyester fiber floss 51. The second isolation layer 7 is polyurethane foam, and the third isolation layer 6 is glass fiber floss, a cold-proof material. Since the outer side of the door body 1 is an irregular curve, the internal installation area is also irregular. The injection of epoxy foam 52 makes it easy to fill the space tightly to ensure thermal insulation performance.

[0025] In some other embodiments, an aluminum honeycomb 4 is provided on the surface of the polyester fiber filament 51, which has the advantages of high strength and light weight. The aluminum core of the honeycomb aluminum plate and the honeycomb structure formed between the plates during production provide good heat insulation and sound insulation effects, and are suitable for places requiring good heat preservation and sound insulation performance.

[0026] Observe again Figure 1 In this embodiment, in order to provide a first mounting edge on the outer edge of the outer glass, i.e., the second glass 3, a second mounting edge is provided on the second mounting area, and the first mounting edge matches the second mounting edge. Usually, the second mounting edge is provided in a stepped manner, which facilitates the installation and fixation of the second glass 3 and improves the sealing of the installation.

[0027] In some other embodiments, the second glass 3 is designed as a two-layer hollow glass structure, and the number of layers is set according to demand. The outer layer of glass has a smaller area, and the inner layer of glass gradually increases in area. During production, the center of each layer of glass in the second glass 3 is coaxially arranged; usually after the second glass 3 is installed, the outermost glass surface of the second glass 3 is tangent to the outer wall installation end of the door panel frame 101. In layman's terms, after the second glass 3 is installed, it forms a smooth curved surface with the outer wall of the door panel frame 101 to improve the overall beauty of the door leaf.

[0028] Principle and installation of this application design:

[0029] The interior of the door panel frame 101 is filled with epoxy foam 52 and polyester fiber floss 51 to improve the sound insulation and heat insulation performance of the door leaf body; the cavity of the door panel frame 101 body profile is filled with low-density polyurethane foam to improve the sound insulation and heat insulation performance of the door panel frame 101 itself, and cut off the sound and heat transmission bridge of the metal material of the frame. The interior of the inner cover shell 102 is filled with cold-proof material glass floss to further improve the overall sound insulation and heat insulation performance of the door leaf from the inside. The door leaf is provided with an outer layer of hollow glass + inner glass structure. The hollow glass adopts a multi-layer hollow structure, forming a multi-layer cavity structure with the inner layer of glass, which can effectively improve the sound insulation performance of the glass. The door leaf as a whole adopts a multi-layer, multi-material structure to form a multi-layer conduction interface, which effectively blocks the transmission path of noise and heat, achieves high sound insulation and high heat insulation performance, and thus effectively improves the comfort of the driver's cab.
