A mechanical energy-absorbing vehicle-mounted fuel tank

Abstract

The invention discloses a mechanical energy-absorbing type vehicle-mounted fuel tank in the automobile field. A left end piston and a right end piston which are sealed and slidably connected with the inner surface are arranged inside a fuel tank body, the right middle of the right end piston is fixedly connected with the left end of a right push rod, and the right end of the right push rod is fixedly connected with a right push rod base; the right middle of the left end piston is fixedly connected with the right end of a left push rod, and the left end of the left push rod is fixedly connected with a left push rod base; a left end spring is connected between a left cover and the left end piston, and a right end spring is connected between a right cover and the right end piston; and an active lever is arranged on the right side of the right push rod base, the upper end of the active lever faces to the right push rod base, the lower end of the active lever is connected with the right end of the horizontal section of an L-shaped force transferring rod, the upper end of the vertical section of the force transferring rod is fixedly connected with the left push rod base, when the shaking kinetic energy of oil plants is beyond the storage energy of the left end spring and the right end spring, the right push rod base strikes the upper end of the active rod, and the vessel volume for containing the oil plants is increased, so that the oil plants are in a rebalanced state.

Description

technical field [0001] The invention belongs to the field of automobiles, in particular to an automobile fuel tank structure, which is a fuel tank capable of controlling fuel sloshing. Background technique [0002] With the continuous improvement of vehicle emission indicators, more and more attention is paid to the recovery of oil and gas in vehicle fuel tanks, especially gasoline fuel tanks, whose fuel is volatile and forms a lot of oil and gas. The formation of oil and gas in the fuel tank is inseparable from the pressure and temperature in the fuel tank and the operating conditions of the vehicle. Vehicles in motion operate under various working conditions every day, such as braking, acceleration, uneven road surface, sharp turns, etc. However, the fuel in the fuel tank is accompanied by violent shaking with the occurrence of various working conditions of the car. It will have the following effects: 1. The fuel hits the wall of the fuel tank back and forth, causing alte...

Problems solved by technology

However, the disadvantage of this solution is that it increases the thickness of the fuel tank, reduces the usable volume of the fuel tank, and at the same time only reduces the amplitude of shaking. The force on the fuel is in an unbalanced state most of the time, that is, the fuel is still in motion. And the energy of oil sloshing is consumed, not recycled
