Description
Technical Field
The present invention relates to a fuel tank cap buffer mechanism, and more particularly to a fuel tank cap buffer mechanism for a vehicle.
Background
In the prior art, the oil tank cap is actuated by the spring torsion after being opened, the oil tank cap rotates upwards to a fixed position by taking the rotating shaft as a center, the oil tank cap impacts the stopping part due to the kinetic energy generated by the spring torsion before the fixed position, the oil tank cap impacts the stopping part to generate impact residual waves to shake, and then the shake is stabilized at the stopping part due to the spring torsion.
However, the fuel tank cap shaking performance not only reduces the merchantability of the entire vehicle and reduces the purchase desire of consumers, but also easily causes the wear of components such as a mechanism and a spring, thereby reducing the service life. The inventor is concerned with this, and this is in the spirit of active creation, think urgently about a fuel tank cap buffer gear that can solve above-mentioned problem, several research experiments end to accomplish the utility model discloses.

A primary object of the present invention is to provide a fuel tank cap buffer mechanism, through the setting of resistance mechanism and slow moving portion, the fuel tank cap group in the in-process that upwards unscrews, can be according to the progressive resistance of providing of resistance mechanism's outward appearance shape, let the fuel tank cap group do not produce after opening the striking rocking to promote the commodity nature of whole car under the situation that does not promote the cost.
In order to achieve the above object, the fuel tank cap buffering mechanism of the present invention comprises a pedal assembly and a fuel tank cap assembly, wherein the pedal assembly is located at a pedal position of the vehicle body and includes a pedal body, a first rotating shaft portion and a slow moving portion fixed to the pedal body. The fuel tank cover assembly is a cover body for shielding the fuel tank and comprises a fuel tank cover body and a support part fixedly connected to the fuel tank cover body. The support part is provided with at least one resistance mechanism which can correspond to the sliding contact slow-moving part and a second rotating shaft part, the second rotating shaft part is pivoted on the first rotating shaft part by a set of rotating shaft provided with an elastic element, and the support part is assembled on the pedal group by a pressing part.
In the process of screwing the oil tank cover group upwards, the resistance mechanism gradually contacts the slow moving part, so that the slow moving part is slightly deformed according to the appearance shape of the resistance mechanism to form resistance for resisting shaking. Through the design, the utility model discloses a tank cap buffer gear can effectively avoid the tank cap striking produced afterwave to rock behind the backstop portion, and the unnecessary that disappears is initiatively rocked and is quivered, reduces the loss of mechanism and spring unit, promotes the commodity nature of whole car.
The pedal group can further comprise a buckling mechanism, and the oil tank cover group can further comprise a buckling part which can be selectively buckled or separated with the buckling mechanism. Therefore, the oil tank cover group can be buckled with the pedal group by utilizing the mechanical structure, so that the oil tank cover group and the pedal group have a connection relation in a closed state, and better shielding and protecting effects are achieved.
The resistance mechanism may be a tapered structure that provides a progressive frictional resistance. Therefore, the larger the upward screwing-off amplitude of the oil tank cover group is, the larger the frictional resistance can be given by the resistance mechanism according to the conical appearance of the oil tank cover group, so that the oil tank cover group can be stopped at a specific position without excessive impact or shaking.
The bracket part can be further provided with a supporting mechanism which can be arranged on the opposite side of the resistance mechanism and is used for keeping the balance of the oil tank cover group when pivoting. Therefore, under the condition that only one side is provided with the resistance mechanism, the other side is easy to generate a gap to generate the unbalanced condition, so that the oil tank cover group generates deflection in the opening process, and the whole friction resistance is reduced. In addition, the supporting mechanism can be a structural body with equal height and thickness, so that the gap between the opposite sides of the resistance mechanism can be completely filled, and a better supporting effect is provided.
The slow moving part can be a thin plate structure extending downwards from the pedal body. Therefore, in order to make the resistance mechanism successfully generate the frictional resistance, a corresponding slow-moving structure is required, wherein the thin plate structure extending downwards from the pedal body is designed as a simple slow-moving part so as to provide enough frictional resistance.
The width of the thin plate structure of the slow moving part can be larger than the average thickness of the pedal body. Therefore, the slow moving part can provide enough sheet width to contact with the resistance mechanism, and the strength of the friction resistance is maintained.
The thickness of the thin plate structure of the slow moving part can be smaller than the average thickness of the pedal body. Therefore, the slow moving portion can provide a sufficient deformation amount to allow the resistance mechanism to absorb the shock, so that the frictional resistance can be gradually increased.
The foregoing summary, as well as the following detailed description, is exemplary in nature and is intended to further illustrate the claimed invention. Other objects and advantages of the present invention will become apparent from the following description and the accompanying drawings.
