Problems solved by technology

[0002] Automobile fuel tank is the full name of automobile fuel tank. At present, with the development of the automobile industry and the revitalization of the domestic automobile industry, the demand for automobile fuel tanks by major automobile manufacturers has shown an obvious growth trend; most of the existing automobile fuel tanks are single-layer , the vibration is too large when the car is running or when it is hit, and it is easy to damage the fuel tank; and when the car is running or shakes when it is hit, it will cause the fuel in the fuel tank to shake, causing the vehicle to make noise, and the fuel tank will also be affected by the fuel. The impact force brought by the shaking causes the fuel tank to sway and the tank is damaged, which poses a safety hazard

Abstract

The invention provides an automobile fuel tank. The automobile fuel tank comprises an outer shell and an inner shell. A plurality of first buffering devices are arranged between the top and the bottom of the inner shell and between the inner top and the inner bottom of the outer shell. A plurality of second buffering devices are arranged between the outer sidewall of the inner shell and the inner sidewall of the outer shell. The top center of the outer shell is provided with an oil filling pipe. A cover body is arranged at the top end of the oil filling pipe. The oil filling pipe is internally provided with a tubular screen body. The lower end of the oil filling pipe communicates with an oil filling port formed in the top center of the inner shell through a corrugated pipe. A sealing ball used for sealing the oil filling port is arranged under the oil filling port in the inner shell. The lower end of the sealing ball is provided with a supporting plate. A plurality of first springs are arranged at the lower end of the supporting plate. An L-shaped supporting plate is arranged in the position, on one side of the oil filling port, of the inner top wall of the inner shell. The lower ends of the first springs are connected with the horizontal part of the L-shaped supporting plate. The outer wall of the inner shell is provided with a plurality of cooling assemblies. The inner sidewall of the outer shell is provided with a plurality of exhaust fans. Air outlets of the exhaust fans are located outside the outer shell.
