Description

Elastic opening and door opening device using the same {A Opens the door which uses an elastic support system and the system which closes}

The present invention relates to an elastic support and a door opening and closing device using the same, and the elastic support is provided on the inner surface of the oil inlet door so that when the driver operates the open lever and the locking piece is released from the locking lever, the oil filling door is completely automatic. It relates to an elastic support and a door opening and closing device using the same.

In general, the filling port of the vehicle is double blocked. That is, a cap that directly blocks the filling port, and a door that blocks the cap from the outside to keep the aesthetics of the vehicle beautiful and to prevent theft of fuel.

The door is rotatably hinged to a housing that creates a space enclosed therein from the body surface, and a locking piece and a locking lever are provided at a position on the housing corresponding to the open end so that the door is locked when the door is closed. The door is kept locked.

On the other hand, in order to open the door by operating the open lever installed near the driver's seat by pulling the cable connected thereto, the locking state with the locking piece is configured to open the door.

However, in order to automatically open the conventional oil filling door by the operation of the open lever, a separate device for automatically opening the door is required.

1 and 2 are diagrams illustrating a filling port door of a conventional vehicle.

As shown in FIGS. 1 and 2, the door opening and closing device of the conventional vehicle is supported by the hinge bracket 12 fixed to the vehicle body so that the door 10 may be opened and closed in the form of a case from the vehicle body. A locking piece 18 is provided on one side to maintain a locked state when the lock 10 is closed, and the hinge bracket 12 is provided with a support 14, and a plate having elastic force in the support 14. When the spring 16 is provided and the locked state of the door 10 is released by the elastic force of the leaf spring 16, one side is provided to protrude outwardly with respect to the hinge bracket 12.

The shock absorber 20 is provided on the inner surface of the door 10 to absorb the shock generated when the door 10 is closed and to prevent the door 10 from directly contacting the vehicle body, thereby protecting the vehicle body and the door 10. ) Is provided.

The conventional oil filling door 10 configured as described above releases the locking state of the locking lever 22 and the locking piece 20 by pulling the cable 24 connected thereto when the open lever (not shown) provided near the driver's seat is operated.
