Description

Fuel filler cap shock absorption mechanism

The invention relates to a fuel filler cap shock absorbing mechanism, in particular to a fuel filler cap shock absorbing mechanism which can alleviate the impact between a spiral arm and a fuel filler seat.

In general, most of the fuel filler caps in vehicles are designed to be automatically pop-opened, and the operation mode is to use the main switch key to turn to the positioning to automatically pop open the fuel filler cap. When the fuel filler cap is opened, due to the inertia, the fuel filler cap usually reciprocates and rebounds several times before it can stand still. In addition, in order to ensure that the fuel filler cap can be automatically and automatically opened, the spring force of the spring for popping the fuel filler cap is often designed to be large. However, the increased spring force will cause the fuel filler cap to spring back to the fuel filler. For example, the problem that the above-mentioned fuel filler cap will bounce back to the fuel filler port may appear in the structure of the integrated fuel tank lock shown in the Republic of China Patent Publication No. 396999.

In view of the above, an object of the present invention is to provide a fuel filler cap shock absorbing mechanism which can achieve a shock absorbing cushioning effect in a limited space, and has the advantages of simple structure and low cost.

The present invention basically employs the features detailed below in order to solve the above problems. That is, the present invention is applicable to a vehicle and includes a fuel filler seat; a swing arm is coupled to the fuel filler seat in a rotating manner; a fuel filler cap is coupled to the swing arm and is Separatingly covering the fuel filler seat body; and a shock absorbing member coupled to the swing arm and detachably abutting the fuel filler seat body with the rotation of the swing arm for buffering the spin The impact between the arm and the fuel filler seat.

Meanwhile, the fuel filler cap shock absorbing mechanism according to the present invention further includes a pivot shaft that is disposed in the swing arm and the fuel filler seat body, wherein the swing arm is supported by the pivot shaft relative to the fuel filler seat The body rotates.

In the present invention, the fuel filler cap shock absorbing mechanism further includes a torsion spring disposed on the pivot shaft and coupled between the fuel filler seat body and the damper member, wherein the fuel filler cap is The fuel filler seat body is separated by the elastic force provided by the torsion spring.

In the present invention, the damper member has a through slot, and the torsion spring is hooked in the through slot.

Also in the present invention, the damper member is made of an elastic material.

The above described objects, features and advantages of the present invention will become more apparent from the description of the appended claims.

The preferred embodiment of the invention is described in conjunction with the drawings.

Referring to FIG. 1 , the fuel filler cap shock absorbing mechanism 100 of the present embodiment may be suitable for use in a vehicle to achieve a shock absorbing effect in a limited space.

Referring to FIG. 2A , FIG. 2B and FIG. 3 , the fuel filler cap shock absorbing mechanism 100 mainly includes a fuel filler seat body 110 , a spiral arm 120 , a fuel filler cap 130 , a damping component 140 , a pivot 150 and a Torque spring 160.

The arm 120 is coupled to the fuel filler seat body 110 in a rotational manner.

The fuel filler cap 130 is coupled to the swing arm 120, and the fuel filler cap 130 is detachably covered to the fuel filler seat body 110.

The damper member 140 is coupled to the swing arm 120, and the damper member 140 is detachably abutted against the fuel filler seat body 110 as the swing arm 120 rotates to buffer the swing arm 120 and the fuel filler seat body 110. The impact between. Here, the damping element 140 may be made of an elastic material such as rubber. Further, in the present embodiment, the damper member 140 and the arm 120 are coupled together in such a manner as to be engaged with each other. Further, as shown in FIG. 4, the damper member 140 has a through groove 141.

As shown in FIGS. 2A, 2B, and 3, the pivot 150 is disposed through the arm 120 and the filler seat body 110. Here, the arm 120 is rotated relative to the filler seat body 110 by the pivot 150.

The torsion spring 160 is threaded over the pivot 150 and the torsion spring 160 is coupled between the filler seat body 110 and the damping element 140. More specifically, as shown in FIG. 4, one end of the torsion spring 160 is coupled to the fuel filler seat body 110, and the other end of the torsion spring 160 is hooked into the through groove 141 of the damper member 140. Therefore, the fuel filler cap 130 can be separated from the fuel filler seat body 110 by the elastic force provided by the torsion spring 160.

As described above, when the fuel filler cap 130 is separated from the fuel filler seat body 110 by the elastic force provided by the torque spring 160 from the position shown in FIG. 2A or is opened to the position shown in FIG. 2B, the damper member 140 One end (for example, opposite one end of the through groove 141) abuts against the fuel filler seat body 110. At this time, since the damper member 140 is made of an elastic material, it can cushion the impact force between the slewing arm 120 and the fuel filler seat body 110. In other words, even if the elastic force provided by the torsion spring 160 is large, the fuel filler cap 130 does not rebound back to the fuel filler seat body 110 by the cushioning action of the damping component 140, so that the fuel filler cap 130 or the entire fueling can be lifted. The operation of the flap shock absorbing mechanism 100 is smooth.

Further, in addition to the buffering effect mentioned above, the damper element 140 has the advantages of easy installation and low cost. Therefore, the fuel filler cap shock absorbing mechanism 100 of the present embodiment can be widely applied to various vehicles, and can promote the development of related industries.

Although the present invention has been disclosed in its preferred embodiments, it is not intended to limit the present invention, and it is possible to make some modifications and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
