Vehicle Fuel Filler Structure

Abstract

The invention provides a vehicle oil filler structure. The vehicle oil filler structure comprises an oil filler tube and an oil filler cap in pivot connection with the oil filler part of the oil filler tube, an overhung hinge arm is formed on one side of the oil filler tube, and a connecting arm corresponding to the hinge arm is formed on the oil filler cap and is in pivot connection with the hinge arm through a rotating shaft; the vehicle oil filler structure further comprises an opening spring which sleeves the rotating shaft and is arranged on one side of the hinge arm and the connecting arm, and the two ends of the opening spring are connected with the hinge arm and the connecting arm respectively. The vehicle oil filler structure can avoid the existing problem that due to the inconsistency of a rotating shaft of an oil filler cap and the rotation axis of an opening spring, an opening critical point is generated; besides, by arranging the opening spring on one side, there is no need to change the structure of the hinge arm or the connecting arm, designing and manufacturing of the overall structure are facilitated, and thus the vehicle oil filler structure has high practicability.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle fuel filler structure. Background technique [0002] In the existing vehicle fuel filler structure, the rotation axis of the fuel filler cap and the rotation axis of the fuel filler cap opening spring are generally not unified, resulting in a critical point in the opening process of the fuel filler cap. The cap receives the least force from the opening spring and is in a force-balanced state. After passing the critical point, the force of the spring on the fuel cap will gradually increase, so that the existence of the critical point makes the process of opening the fuel cap difficult. , affecting the practicality of the fuel filler cap. And because the fuel filler cap is being opened, it is only subjected to the active force of the opening spring, so the opening rate of the fuel filler cap is difficult to control, and it is easy to affect the stability of the fuel fil...

Problems solved by technology

[0002] In the existing vehicle fuel filler structure, the rotation axis of the fuel filler cap and the rotation axis of the fuel filler cap opening spring are generally not unified, resulting in a critical point in the opening process of the fuel filler cap. The cap receives the least force from the opening spring and is in a force-balanced state. After passing the critical point, the force of the spring on the fuel cap will gradually increase, so that the existence of the critical point makes the process of opening the fuel cap difficult. , affecting the practicality of the fuel filler cap

And since the fuel filler cap is being opened, it is only subjected to the force of the opening spring, so the opening speed of the fuel filler cap is difficult to control, and it is easy to affect the stability of the fuel filler cap.

In addition, after the existing fuel filler cap is closed, it is only fixed on the fuel filler pipe through the locking device formed by the rotating shaft at both ends, the pin shaft and the cable head. As the vehicle drives, the fuel filler cap is prone to looseness. , resulting in the appearance of collision noise, which also affects the practicability of the fuel filler structure
