Description

[Detailed Description of the Invention] The present invention relates to an improvement of a trip meter for an automobile, and more particularly to a trip meter equipped with a release mechanism in which the counter automatically returns to zero when refueling with gasoline.

Previously, it was necessary to operate a knob to return the trip meter counter to zero. Therefore, drivers who use mileage as a guideline for refueling have had to return the fuel to zero by operating the knob each time.

It is an object of the present invention to provide a release mechanism that can return the trip meter counter to zero without operating the trip meter knob as in the prior art.

Therefore, in the present invention, a lever for a fuel lid oven and a reset device for a trip meter are connected by a wire cable or the like.

To specifically explain the illustrated embodiment, numeral 1 in the figure is a trip meter and is equipped with a knob 2. As shown in FIG. Reference numeral 3 denotes a knob for a fuel lid oven, which is attached to the end of a lever 4 for the fuel lid oven, and the lever 4 is formed into a bell crank shape with a support shaft 5 as the center.
A wire cable 6 led out from the locking device of the filler lid is connected to one end to enable the filler lid to be unlocked, and a wire cable 6' connected to the trip meter 1 is connected to the other end of the lever 4. There is.

The reset device for the trip meter 1 includes a cam plate 9 pivoted by the same number of pivots 10 as the number wheels 7 at positions corresponding to the cams 8 attached between the number wheels 7 arranged in rows as shown in FIG. , an occlusal tooth 12 that meshes with a tooth 11 formed at the base end of the cam plate 9, a rod 13 integrally extending from the knob 2 with the occlusal tooth 12 fixed near the tip, and a rod 13 attached to the cam plate 9. When the rod 13 is pressed by the knob 2, the teeth 11 of the cam plate 9, which mesh with the occlusal teeth 12, move the pivot 10 by the occlusal teeth 12 fixed to the tip of the rod 13. The cam plate 9 rotates rearward about the center, and therefore, the tip of the cam plate 9 rotates forward. When the tip of the cam plate 9 rotates forward, the tip of the cam plate 9 contacts the cam 8 and rotates the number wheel 7 together with the cam 8.

Although not shown, a gear is integrally formed between the number wheel 7 and the cam 8, and each number wheel 7 can be rotated individually by rotation of the gear. Further, the size of the occlusal teeth 12 should be such that when the knob 2 is turned, the meshing with the teeth 11 of the cam plate 9 does not come out of engagement.

A rotary locking piece 14 is provided at the tip edge of the rod 13, and a locking piece 16 is provided on the rod 15 provided at the tip of the wire cable 6' and is releasably engaged with the rotary locking piece 14. The locking piece 16 overlaps and locks the rotational locking piece 14, and when the rotational locking piece 14 turns 90 degrees as shown by the dotted line in the figure, the locking piece 16
The locking action with is released. The rotation locking piece 14 and the locking piece 16 are each formed into a flat shape so as to be in surface contact with each other.

If you wish to reset the counters on each number wheel 7 of the trip meter 1 to zero by operating the fuel lid oven knob 3, operate the trip meter knob 2 and turn the rod 13. Turn the locking piece 14 to the position indicated by the solid line.

Then, when the fuel lid oven knob 3 is operated in the direction of the arrow as shown in FIG. As shown in FIG. 2, the cam plate 9 contacts the cam 8 of the number wheel 7 to rotate the number wheel 7 in order to rotate the cam plate 9 through the occlusal teeth 12 in order to pull in the direction of the arrow. I return the number wheel 7 counter to zero. Also, if the trip meter knob 2 is pushed independently of the fuel lid oven knob 3, the occlusal teeth 12 will advance and the cam plate 9 will be rotated to rotate the cam 8 of the number wheel 7 as described above.
The counter of the number wheel 7 can be returned to zero by turning the number wheel 7 in contact with the number wheel 7.

Next, in order to prevent the trip meter 1 from returning to zero even when the fuel lid oven knob 3 is operated, turn the rod 13 and lock the rotation locking piece 14.
When it is tilted to the position shown by the dotted line in FIG. 2, it will separate from the locking piece 16, so even if the knob 3 is operated, the rod 13 cannot be pulled. Therefore trip meter 1
The counter on number wheel 7 cannot be returned to zero.

As described above, according to the present invention, if you want to use the trip meter to check the mileage each time you drive or calculate the fuel consumption, you can simply operate the fuel lid oven knob to check the trip meter each time you refuel. The counter of the trip meter can be set to zero without pressing the knob to reset the trip meter, thereby saving the effort of operating the knob of the trip meter. Furthermore, by turning the trip meter knob, communication with the fuel lid oven knob can be cut off, and the trip meter can be returned to zero by itself using the trip meter knob, which is convenient in practice.
