Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail: as figure 1 as shown,

[0014] This automobile fuel tank includes a fuel tank oil inlet 1 and a fuel tank inner cavity 5, and also includes a fuel tank shell 2, the fuel tank shell 2 and the fuel tank inner cavity 5 are made of high-density polyethylene material, and the fuel tank shell 2 There is a flame-retardant layer 3 between the fuel tank inner cavity 5, and the flame-resistant layer 3 is made of asbestos material. There is a buffer cavity 6 between the flame-resistant layer 3 and the fuel tank inner cavity 5. In the buffer cavity 6, A buffer component 4 is provided on each side of the inner chamber of the fuel tank 5, and the buffer component 4 is made of flame-retardant rubber.

Abstract

The invention discloses an automobile fuel tank and relates to the technical field of automobile manufacturing. The automobile fuel tank comprises a fuel tank oil inlet, a fuel tank inner cavity and a fuel tank shell, wherein a fire-retardant layer is arranged between the fuel tank shell and the fuel tank inner cavity, a cushion chamber is formed between the fire-retardant layer and the fuel tank inner cavity, and a buffer unit is arranged between the inner portion of the cushion chamber and at least one side surface of the fuel tank inner cavity. The automobile fuel tank can solve the problems that the impact resistance is poor and fire cannot be prevented for the existing automobile fuel tank.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an automobile fuel tank comprising a multi-layer structure and filled with media between layers. Background technique [0002] Existing automobile fuel tanks are mostly plastic fuel tanks, and their tank walls are mostly single-layer structure or composite structure. These plastic fuel tanks have the following deficiencies: 1. Under high-temperature environments, especially when a fire occurs outside the tank, The temperature of the fuel will rise rapidly, which is prone to explosion; 2. The buffer effect of the fuel tank is poor. When the car is driving on a bumpy road, the fuel in the fuel tank will collide, posing a safety hazard; When the internal fuel sloshes, it has a certain slowing effect on the impact of the fuel tank, but it cannot fundamentally solve the problem of fuel sloshing caused by vehicle bumps. Contents of the invention [0003] The object ...
