Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vehicle fuel lid.

[Prior Art] A conventional vehicle fuel lid is generally provided with a fuel filler port 52 formed on a side surface of a vehicle body 50 so as to surround a peripheral portion of a tank cap 51 of a fuel tank, as shown in Figs. A lid plate 53 capable of covering the oil supply port 52 is provided via a hinge 54 so as to be openable and closable.

[Problems to be Solved by the Invention] In the conventional rotary fuel lid for a vehicle, when the lid plate 53 is opened, the open end portion of the plate 53 is largely projected to the side surface of the vehicle body 50. Therefore, for example, the following restrictions are imposed.

For example, in a vehicle 57 having a hinged side door 56 as shown in FIG. 10, when the lid plate 53 is arranged near the rear of the door 56, the lid plate 53 as shown in FIG. When the door is opened, the side door 56 is accidentally opened, and the key 58 inserted into the key cylinder of the lid plate 53 interferes with the side door 56.

Further, as shown in FIG. 12, in the vehicle 61 having the sliding side door 60, when the lid plate 53 is arranged near the rear of the door 60, as shown in FIG. When the door is opened, the side door 60 is accidentally slid and opened, and the lid plate 53 and the side door 60 interfere with each other.

Further, as shown in FIGS. 14 and 15, when the lid plate 53 is arranged in the vicinity of the rear fender portion 64 of the vehicle 63 while straddling the rear fender portion 64, the plate 53 is opened when the lid plate 53 is opened. A large notch 65 has to be formed in the fender portion 64 so that the hinge side end portion thereof does not interfere with the fender portion 64, resulting in poor appearance.

Further, a relief is formed on the side surface of the vehicle body, and in the lid plate 53 that straddles this relief, an arm type hinge must be adopted so that the plate 53 does not interfere with the relief portion when the lid plate 53 is opened. . In addition, in the case of this arm type hinge, deterioration of weight, cost, appearance, etc. is forced.

As described above, the hinge-type fuel lid for a vehicle is limited in its design because it is subject to some restrictions depending on its location.

Therefore, the present invention has been made in order to solve the above-mentioned problems, and an object thereof is to provide a vehicle fuel lid capable of increasing the degree of freedom in design and improving the commercialability.

[Means for Solving the Problems] A vehicle fuel lid according to the present invention for solving the above problems includes a fuel filler port provided on a side surface of a vehicle so as to surround a peripheral portion of a tank cap of a fuel tank. A lid plate that opens and closes is provided so as to be movable in parallel in a horizontal direction via a parallelogram-shaped four-bar link mechanism, and the lid plate is connected to the four-bar link mechanism so as to be slidable in the vehicle longitudinal direction.

[Operation] According to the above means, the lid plate that closes the fuel filler opening is opened in parallel via the four-bar linkage and the lid plate is slid with respect to the four-bar linkage to open the fuel filler. Be done.

Also, by sliding the open lid plate in the opposite direction to the above with respect to the four-bar linkage, and turning the lid plate to the lid mounting part via the four-bar link mechanism while keeping the parallel state, the lid mounting part Is closed.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1 showing a fuel lid for a vehicle in a plan sectional view and FIG. 2 showing a fuel filler port of a vehicle body in a front view, a substantially rectangular fuel filler port 2 is provided on a side surface of a vehicle body 1 such as a quarter panel. Is recessed. A tank cap 4 of the fuel tank is arranged in the opening hole 3 opened in the fuel filler port 2.

A mounting base 6 is attached to the fuel filler port 2 by a bolt or the like. The mounting base 6 is formed in a plate shape surrounding the opening hole 3.

The mounting base 6 has upper and lower mounting portions 7 protruding from one side thereof (for example, the front side of the vehicle). A quadrilateral link mechanism 9 having a parallelogram shape is provided on each mounting portion 7.

As shown in the perspective view of FIG. 4, the four-bar linkage mechanism 9 has one ends of the front and rear link stays 10 rotatably mounted on the mounting base 6 via shafts 11, and both links. Both ends of the connecting link 12 are rotatably attached to the tip of the stay 10 via shafts 13.

A spring 15 is interposed between the link stay 10 and the mounting portion 7. The spring 15 includes a coil spring portion 16 fitted and inserted into the shaft 11, an arm portion 17 extending from one end of the spring portion 16 and having a tip end thereof mounted on the mounting portion 7, and the spring portion 16 Has an arm portion 18 extended from the other end and having its tip end hooked on the link stay 10. Due to the elasticity of the spring 15, the link stay 15 is always in the upright state, that is, the four-bar linkage mechanism 9 is urged in the deployed state. A stopper 19 for stopping the link stay 15 in the standing state against the elasticity of the spring 15 is provided on the mounting portion 7.

A pair of guide rollers 20 are rotatably attached to the shafts 13 at both ends of the connecting link 12.

A lid plate 22 that covers the fuel filler port 2 is attached to each of the four-bar linkage mechanisms 9 as follows. That is, upper and lower guide rails 23 having a channel-shaped cross section are formed in parallel on the back surface of the lid plate 22, as shown in the back surface perspective view of FIG.

A guide roller 20 of the four-bar linkage mechanism 9 is rotatably engaged with the guide rail 23 as shown in a sectional view of FIG. Therefore, the lid plate 22 is slid in the vehicle front-rear direction through the rolling of the guide roller 20. It should be noted that end pieces 24 are fitted to both front and rear ends of the guide rail 23 as shown in FIG. End piece 24
Prevents the guide roller 20 from coming off the guide rail 23.

A lid lock device 26 is attached to each of the upper and lower walls of the fuel filler port 2 of the vehicle body 1. The lid lock device 26 is well known, and normally has a lock pin 28 that is biased to a protruding state by elastic means (not shown) and is pulled against the elastic means by pulling a cable 27. The end of the cable 27 on the operation side is arranged near the driver's seat, and the lock pin 28
Can be remote controlled. This lock pin 28
When the lid plate 22 is closed, that is, when the four-joint link mechanism 9 is folded, by locking one of the link stays 10, the four-joint link mechanism 9 is deployed and rotated against the elasticity of the spring 15. Prevent. A guide protrusion 29 is provided on the side surface of the link stay 10 as shown in FIGS. For this reason, when the lid plate 22 is closed, the arcuate slope of the guide protrusion 29 becomes the lock pin.
The plate 22 is closed while pushing in 28, and at the same time as the closing is completed, the lock pin 28 returns to the projecting state and is locked to the link stay 10.

In the vehicle fuel lid, when the lock pin 28 of the lid lock device 26 is retracted by operating the cable 27 from the lid shut state shown by the solid line in FIG. 1, the four-joint link mechanism 9 is locked to the link stay 10. It will be canceled. Then, the link stay 10 is raised by the elasticity of the spring 15 and the four-bar linkage mechanism 9 is expanded, so that the lid plate 22 is moved in parallel in the horizontal direction and the fuel filler port 2 is opened by a predetermined amount, so-called pop-up ( First
(See two-dot chain line A in Fig.). After that, when the lid plate 22 is slid forward of the vehicle (rightward in FIG. 1), the fuel filler port 2 is opened (see the chain double-dashed line B in FIG. 1). After that, if the tank cap 4 is removed, refueling becomes possible.

In this lid open state, the lid plate 22 is in a state of being parallel to the outer surface of the vehicle body 1 in a state of slightly overhanging. Therefore, the overhang amount of the lid plate 22 can be smaller than that of the conventional hinged fuel lid.

Further, in the lid plate state, contrary to the above, the lid plate 22 is slid to the rear of the vehicle (to the left in FIG. 1) to the state of the chain double-dashed line A in FIG. 1, and the lid plate 22 is pushed into the fuel filler port 2. Then, the four-bar linkage 9 is folded against the elasticity of the spring 15. afterwards,
As the link stay 10 rotates, the lock pin 28 guides the guide.
As a result of being once pushed in by 29 and returning to the original state, the lid plate 22 is held in the locked state (see the solid line in FIG. 1).

According to the vehicle fuel lid, the protrusion amount of the lid plate 22 from the vehicle body 1 at the time of lid opening can be smaller than that of the conventional hinged fuel lid.
Therefore, it is possible to avoid the interference between the lid key and the lid plate 22 that occurs in the conventional lid plate with a key cylinder, the interference between the side door and the lid plate 22 that occurs in the case of a sliding side door, and the like.

Further, since the four-bar linkage mechanism 9 is used, the interference with the vehicle body 1 due to the opening and closing of the lid plate 22 hardly occurs. Therefore, for example, as shown in FIGS. 6 and 7, even when the lid plate 22 is arranged on the fender portion 30 of the vehicle, a cutout for avoiding the interference of the lid plate 22 is formed on the fender portion 30 as in the conventional case. It does not have to be made large, and a good-looking appearance is obtained. The open state of the lid plate 22 is shown by a chain double-dashed line in FIGS.

Further, when the lid plate 22 is arranged so as to straddle the relief formed on the side surface of the vehicle body, the length of the link stay 10 of the four-bar linkage mechanism 9 should be set in consideration of the relief amount of the relief. Can be selected.

As described above, according to the vehicle fuel lid of this example,
Compared with the conventional one, there is almost no restriction due to the arrangement location, so that the degree of freedom in design is increased.

[Effect of the Invention] According to the vehicle fuel lid of the present invention, the lid plate is opened by the parallel movement so as to be along the side surface of the vehicle body. Interference with the lid plate, deterioration of appearance, restrictions on design, etc. can be eliminated, and as a result of increasing the degree of freedom in design, the commercialability of the vehicle can be improved.
