An anti-corrosion layer is provided on the side of the aluminum alloy plate away from the car body, and a heat insulation layer is provided on the side of the anti-corrosion layer away from the aluminum alloy plate. A coloring layer is provided on the outer wall of the heat insulation layer. Uniformly distributed triangular grooves are formed throughout the longitudinal surface of the aluminum alloy plate. Uniformly distributed shock-absorbing grooves are also formed throughout the longitudinal surface of the aluminum alloy plate, with the triangular grooves and shock-absorbing grooves interleaved. The shock-absorbing grooves are cylindrical. A shock-absorbing assembly is disposed within the shock-absorbing grooves. The shock-absorbing assembly includes a base plate and a cylindrical column. One end of the base plate is mounted on the car body, and one end of the cylindrical column is mounted within the shock-absorbing groove cavity. A buffer section is provided between the base plate and the cylindrical column.

[0007] According to the aforementioned aluminum skin structure of the intercity rail passenger car head, a mounting hole is provided through the bottom plate, and a protruding column is fixedly connected at the center position of the bottom plate near the cylindrical column.

[0009] According to the aluminum skin structure of the intercity rail passenger car head, a magnetic block is embedded in the center of the moving plate, and the protrusion and the magnetic block are magnetically attracted to each other.

[0010] According to the aforementioned aluminum skin structure of the intercity rail passenger car head, a buffer groove is provided on the inner wall of the movable cavity, and a guide rod is fixedly installed in the buffer groove.

[0011] According to the aforementioned aluminum skin structure of the intercity rail passenger car head, the buffer part includes a rubber sleeve slider fixedly installed on the outer wall of the movable plate, and the rubber sleeve slider is movably engaged in the corresponding buffer groove.

[0013] This utility model provides an aluminum skin structure for the front of an intercity rail passenger car. It has the following beneficial effects:

[0014] (1) By setting anti-corrosion layer, heat insulation layer and coloring layer on aluminum alloy plate, the stability, durability and heat insulation performance of the product can be increased. By opening evenly distributed triangular grooves through the longitudinal surface of aluminum alloy plate, stress can be dispersed, the deformation and damage of aluminum alloy plate can be reduced, and the aluminum alloy plate can withstand greater wind pressure or impact force. By opening shock-absorbing grooves on aluminum alloy plate and setting shock-absorbing components in the shock-absorbing grooves, the shaking between aluminum alloy plate and vehicle body can be reduced.

[0015] (2) By opening mounting holes in the base plate, it is easy to install the base plate on the vehicle body. The cylinder is installed in the shock-absorbing groove. By fixing the protruding column on one side of the base plate, and by opening a movable cavity on the cylinder, the movable plate is movably engaged in the movable cavity. The magnetic block is embedded in the movable plate. The protruding column and the magnetic block are magnetically attracted. When the aluminum alloy plate shakes, the shaking of the aluminum alloy plate is buffered by setting a buffer part to reduce vibration.

[0016] (3) A buffer groove is opened on the inner wall of the active cavity, and the guide rod is fixedly installed in the buffer groove. A rubber sleeve slider is fixedly installed on the outer wall of the moving plate. The rubber sleeve slider is movably engaged in the corresponding buffer groove. The guide rod moves through the corresponding rubber sleeve slider. The rubber sleeve slider and the guide rod rub against each other. Due to the high elasticity of rubber, when subjected to external force, it will deform and absorb some energy, thereby reducing the impact of external force. A compression spring is set to reset the rubber sleeve slider. Attached Figure Description

By opening evenly distributed triangular grooves 14 through the longitudinal surface of the aluminum alloy plate 10, stress can be dispersed, reducing the deformation and damage of the aluminum alloy plate 10, enabling the aluminum alloy plate 10 to withstand greater wind pressure or impact. By opening a shock-absorbing groove 15 on the aluminum alloy plate 10 and setting a shock-absorbing component in the shock-absorbing groove 15, the shaking between the aluminum alloy plate 10 and the vehicle body can be reduced.

[0027] A mounting hole 19 is provided through the base plate 16, and a protruding post 18 is fixedly connected to the center of the base plate 16 near the cylindrical column 17.
