Abstract
A stiffness reinforcement structure for a fuel tank of a vehicle is capable of maintaining the stiffness of the fuel tank even with changes in pressure such as positive pressure and negative pressure in the fuel tank. In particular, a stiffness reinforcement column inside a fuel tank made of a plastic material is capable of preventing heat fused portions between the reinforcement column and the upper and lower plates of the fuel tank from being ruptured by allowing the stiffness reinforcement column to have self-reactive impact dispersion movement in case of a vehicle collision accident.
Claims10
A stiffness reinforcement structure for a fuel tank of a vehicle, the stiffness reinforcement structure comprising:
- a reinforcement column including an upper end part and a lower end part;
- an upper fusing structure including a first locking structure configured to lock the upper end part of the reinforcement column, the upper fusing structure configured to be fused on an inner top surface of the fuel tank;
- and
- a lower fusing structure including a second locking structure configured to lock the lower end part of the reinforcement column, the lower fusing structure configured to be fused on an inner bottom surface of the fuel tank;
- wherein the upper end part of the reinforcement column is removably inserted into and locked to the first locking structure, and the lower end part of the reinforcement column is removably inserted into and locked to the second locking structure,
- wherein the first locking structure is integrally provided at a lower side of the upper fusing structure, thereby providing a locking space where the upper end part of the reinforcement column is inserted in a horizontal direction and is provided with an opening at one side thereof, thereby allowing the reinforcement column to be accessed when assembled, and
- wherein a first locking lever is integrally provided at a part of a periphery of the first locking structure, thereby exerting an elastic restoring force to an original position when opened outward.
