Description

Filling Reed Switch {FUEL LID OPENING / CLOSING DEVICE}

The present invention relates to an oil receptacle lead opening and closing device, in which the locking means and the push-up means are appropriately arranged and modularized (one modular) to reduce the number of parts and the number of assembly processes and to save space. .

An actuator of a refueling door is conventionally known for locking in a position where the refueling door is closed (see specification 4 in the US Patent No. 631877, lines 1 to 26, and Figs. 1 to 3, 10 and 11).

The above-mentioned conventional actuator uses a lock arm, supports the middle of the lock arm so as to be rotatable by a pin, and has a lock portion at one end that is fitted to a hook-shaped catch at the rear of the oil supply door. . The pin is eccentrically formed in the outer gear driven by the motor, and the outer gear is rotated to tilt the lock arm around the pin.

Patent Document 1: US Patent No. 631877

Specifically, as shown in FIG. 20, the spring 250 is connected to the sleeve 240 in a state in which the rotor 230 and the sleeve 240 are inserted into the lower rod portion 223 of the rod main body 220. It is inserted and communicates. The spring 250 is compressed between the protrusion 242 of the sleeve 240 and the bottom of the rod case 200.

(Boots (260))

The boots 260 are stretchable to cover the upper rod portion 222 protruding from the rod case 200, as shown in FIGS. 20 and 21, and are installed on the flange portion 201 of the rod case 200. .

Specifically, as shown in Figs. 20 and 21, the boot 260 is formed in a hollow pleat with a lower surface open, and the upper end is closed in a bag shape.

On the inner circumferential surface of the upper end of the boot 260, as shown in Fig. 20, an annular projection 261 protruding annularly inward in the radial direction is formed. The annular projection 261 is fitted into the annular groove 226 of the rod main body 220.

The inner circumferential surface of the lower surface of the opening of the boot 260 is formed with an annular convex portion 262 protruding in an annular direction inward in the radial direction. The annular convex portion 262 is fitted into the annular recess 202 of the flange portion 201 of the rod case 200, and the boot 260 is fixed to the rod case 200.

(Operation of the push rod 140)

Next, the operation of the push rod 140 having the above-described configuration will be described.

Push rod 140 is assembled as shown in FIG. 20, the housing case 100 by fitting the rod case 200 in accordance with the rod holding portion 102 of the housing 100 as shown in FIG. Is fixed relative to).

In the state in which the lid 40 is closed, the push rod 140 is locked in the locked state in which the rod main body 220 is shortened (see FIG. 26).

When the lid 40 is pushed in, the rod body 220 is pushed into the rod case 200 to release the locked state, and the rod body 220 is pushed out of the rod case 200 by the compression restoring force of the spring 250. It protrudes and pushes the lid 40 open.

Therefore, the lid 40 can be easily opened by hand by pushing.

On the other hand, when the lead lead 40 is closed by hand, the rod main body 220 is pushed toward the rod case 200 and locked in the shortened lock state.

(Operation of lock mechanism)

The operation of the locking mechanism will be described.

In the locked state in which the rod main body 220 is shortened, as shown in FIG. 26, the engaging protrusion 233 of the rotor 230 is engaged with the lock groove 216 of the cap 210, and the lock portion ( 216b).

When the rod body 220 is pushed into the rod case 200, although not shown, the rotor 230 is pushed down by being pushed by the cam portion 221 of the rod body 220.

Therefore, although not shown, the engaging projection 233 of the rotor 230 is separated from the lock portion 216b of the cap 210.

At this time, the engagement of the fixed side cam 224 of the cam portion 221 of the rod main body 220 and the movable side cam 232 of the rotor 230 is released, and the rotor 230 in the direction of arrow X in FIG. Rotates.

Subsequently, when the force for pushing the rod main body 220 is released, the rotor 230 is pushed up by the compression restoring force of the spring 250.

At this time, the engaging projection 233 of the rotor 230 is not shown but abuts on the second inclined surface portion 216d of the cap 210. For this reason, the engaging projection 233 is raised while slidingly contacting the second inclined surface portion 216d, and is fitted into the slide groove 215 from the upper end of the slope of the second inclined surface portion 216d (see Fig. 24). .

When it fits in the slide groove 215, as shown in FIG. 24, the engagement protrusion 233 becomes raiseable along the slide groove 215. As shown in FIG.

Therefore, the cam part 221 of the rod main body 220 is pushed up through the rotor 230 by the compression restoring force of the spring 250, and the rod main body 220 protrudes from the rod case 200 and extends. .

On the other hand, if the elongated rod body 220 is pushed into the rod case 200, although not shown, the engaging projection 233 of the rotor 230 is lowered along the slide groove 215.

Next, when the engaging projection 233 comes out of the lower end of the opening of the slide groove 215, the rotor 230 can be rotated.

Therefore, by releasing the engagement of the fixed side cam 224 and the movable side cam 232, the rotor 230 rotates in the direction of the arrow X of FIGS. 24 and 25, and the lower side of the slide groove 215 From toward the first inclined surface portion 216a of the lock groove 216.

Next, when the force for pushing the rod main body 220 is released, the rotor 230 is pushed up by the compression restoring force of the spring 250, and the engaging projection 233 is the first inclined surface portion 216a. Touches. Therefore, the engaging projection 233 is raised while slidingly in contact with the first inclined surface portion 216a, is fitted into the lock portion 216b, and returns to the locked state again.
