Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to the structure of an automobile refueling section, and more particularly to an automobile refueling section provided with a device to prevent forgetting to close the fuel cap after refueling.

(b) Prior art and problems In general, the refueling section of an automobile is as shown in Figure 4.
A fuel cap d is attached to a filler neck c protruding into the recess b of the body a to prevent fuel leakage, and a filler lid f attached to the body a via a hinge e so as to be openable and closable connects the recess b
It has a structure that covers the fillet neck c and fuel cap d. Also, although not shown,
The filler lid f is provided with a locking mechanism that is locked with a key.

Therefore, when refueling, the lock is released, the filler lid f is opened, the fuel cap d is removed, and a refueling gun is inserted into the filler neck c.

However, since the fuel cap d that is removed during refueling is often temporarily placed in a location away from the refueling area, such as in the rear trunk or roof of the vehicle, a refueling person may accidentally remove the fuel cap d. You may forget to tighten it and close the filler lid f.
Furthermore, in the case of a structure in which a spring g is provided on the filler lid f to prevent the filler lid f from opening during driving due to forgetting to engage the lock, it is necessary to open the filler lid f after refueling as shown in Fig. 5. When the refueling gun is pulled out, a force (in the direction of arrow A) that tries to close the filler lid f is applied and the filler lid f is completely closed, making it even more likely that the fuel cap d will be forgotten to be tightened. As a result, the fuel cap d that was left in the rear trunk or the like because it was forgotten to be tightened may fall during driving and be damaged or lost, or the fuel cap may leak and damage the vehicle body (paint peeling, dirt), etc. There is a possibility that

As a prior art technique for preventing forgetting to tighten the fuel cap after refueling, a holding means for removably holding the fuel cap is provided on the back side of the filler lid that covers the fuel inlet so that it can be opened and closed. Jikosho invented a device characterized by a part of the fuel cap protruding when the filler lid is installed to prevent the filler lid from closing.
No. 51-25208. However, this prior art can only function after the fuel cap is attached to the holding means, and if the removed fuel cap is placed in the rear trunk or roof as before, nothing will happen. It was not possible to achieve the intended purpose. In addition, although such conventional technology is convenient as a holding means for fuel caps without plugs, it is not suitable for resin fuel caps with pressure regulating valves, which have recently been improved and are widely used. The plastic fuel cap with pressure regulating valve had the disadvantage of having to be placed in the rear trunk or roof. However, the resin fuel cap with a pressure regulating valve has a plug part that houses the pressure regulating valve, and is large and heavy, so it cannot be held accurately by the holding means used in the prior art, which simply places the fuel cap on. This is because it may fall and cause damage or loss. Therefore, when equipped with a resin fuel cap with a pressure regulating valve, the fuel cap that has been removed as described above must be placed in the rear trunk, roof, etc., as before, so refueling is not possible. It was not possible to reliably prevent forgetting to tighten the fuel cap later.

(c) Purpose of the invention This invention was devised in view of the actual situation.
To provide a fuel supply part for an automobile that is equipped with a mechanism that automatically disables the filler lid by removing the fuel cap, thereby preventing forgetting to tighten the fuel cap.

(d) Structure of the invention In order to achieve the above object, the fuel supply section of an automobile according to the invention has an inclined pressure-receiving surface and a horizontal pressure-receiving surface, and a support that protrudes from the side surface of the recess toward the fuel inlet. It is fitted and supported by the protrusion and is latched onto the support protrusion by a spring, and when the fuel cap is installed, it is moved in the direction opposite to the fuel inlet by the flange of the fuel cap corresponding to the inclined pressure receiving surface. is,
A stopper is provided that moves toward the fuel inlet when the fuel cap is not installed, and a projection is provided on the back surface of the filler lid that comes into contact with the horizontal pressure-receiving surface of the stopper when the fuel cap is not installed.

(e) Embodiments of the invention The invention will be explained in detail below based on FIGS. 1 to 3.

In the figure, reference numeral 1 denotes a fillet neck protruding into a recess 3 formed in a body 2;
A fuel cap 5 having a gasket 4 is detachably attached to the body 2, and a filler lid 6 having a key lock portion (not shown) is attached to the recess 3 of the body 2 so as to be openable and closable via a hinge 7. 3 to protect the fillet neck 1 and fuel cap 5. Although not shown, a spring is attached to the filler lid 6, similar to the spring g shown in FIG. 4, which applies a force (in the direction of arrow B) that tends to close the opened filler lid 6.

Reference numeral 8 denotes a protrusion protruding from the back surface of the filler lid 6, and as shown in FIG.
It is formed so that it comes into contact with the The stopper 9 is provided with a horizontal pressure-receiving surface 9a on its upper portion and an inclined pressure-receiving surface 9b on its side on the filler neck 4 side. Then, a support protrusion 11 protruding from the side surface 3a of the recess 3 in the direction of the fillet neck 1 is fitted into a fitting hole 10 formed on the side surface 9c on the opposite side of the inclined pressure receiving surface 9b. A spring 12 that hooks the stopper 9 and the support projection 11 is stretched between the provided flange 9d and the flange 11a provided near the base of the support projection 11. It is supported so as to be movable in directions (directions C and D in the figure). Moreover, this stopper 9 is connected to the spring 1 when the fuel cap 5 is not installed as shown in FIG.
2 is extended and positioned on the fillet neck opening edge 1a, and when the fuel cap 5 is installed, the flange 5a of the fuel cap 5 is provided so as to come into contact with the inclined pressure receiving surface 9b. Furthermore, when the fuel cap 5 is attached and the spring 12 is shortened as shown in FIG. 3, the stopper 9 is adapted to come into contact with the peripheral surface of the collar 5a. Furthermore, the stopper 9 does not come off the support protrusion 11 when the spring 12 is extended as shown in FIG. 2, and when the spring 12 is shortened as shown in FIG.
The depth of the insertion hole 10 and the length of the support protrusion 11 are set to required dimensions so that the distal end 11b of the support protrusion 11 comes into contact with the stopper 9 and the movement of the stopper 9 in the D direction is not hindered.

Since the present embodiment is configured in this way,
When the fuel cap 5 is removed in the direction of the arrow E during refueling, the stopper 9, which had been pressed against the side surface 3a of the recess 3, is successively pushed back in the direction of the arrow C by the repulsive force of the spring 12, as shown in FIG. 2
Since the filler lid 6 is set in the state shown in the figure, even if an attempt is made to tighten the filler lid 6, the protrusion 8a comes into contact with the horizontal pressure receiving surface 9a of the stopper 9, making it impossible to tighten it.
Therefore, it is possible to remind the refueling person not to forget to close the fuel cap 5. Furthermore, when the fuel cap 5 is tightened and installed in the direction of the arrow F, the stopper 9 is sequentially pressed toward the side surface 3a of the recess 3 by the action of the inclined pressure receiving surface 9b that the flange 5a comes into contact with, and as a result,
As shown in FIG. 3, even when the filler lid 6 is closed, the protrusion 8 on the back side of the filler lid 6 is accommodated in the recess 3 without contacting either the horizontal pressure receiving surface 9a or the inclined pressure receiving surface 9b, so the filler lid 6 is completely closed. This means that you can do it.

(c) Effects of the invention As described above, according to the invention, when the fuel cap is removed, the filler lid is automatically disabled, so that the refueling person can be assured of not forgetting to tighten the fuel cap depending on the open/closed state of the filler lid. This has made it possible to completely prevent forgetting to close the fuel cap after refueling.
