Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to a vehicle ornament with a switch function, which is configured to add a switch function to a vehicle ornament, such as an emblem or a name plate.

(Prior Art) Generally, in automobiles, ornaments such as emblems or name plates are attached to predetermined parts of the trunk, bonnet, doors, etc. in order to enhance the decorativeness of the exterior. On the other hand, in recent years, so-called keyless systems have been adopted as systems for unlocking trunks, bonnets, doors, etc. In this keyless system, a switch device consisting of a plurality of touch switches is installed in a predetermined place such as the trunk, bonnet, or door, and a predetermined recitation code pattern is input by the way the switch is pressed, that is, the number of times it is pressed or the order in which it is pressed. With this, the trunk, bonnet, doors, etc. are unlocked.

(Problems to be Solved by the Invention) However, in the above configuration, since the ornament and the switch device are each separate, the number of parts increases accordingly, and the workability of assembling these parts is poor.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an ornament for a vehicle with a switch function, which can reduce the number of parts by integrating the ornament and the switch device, and thereby improve installation workability.

[Structure of the invention] (Means for solving the problem) The ornament for a vehicle with a switch function of the invention has a shape formed on the surface of a substrate, and a pattern formed on the substrate corresponding to the shape and at a predetermined distance from each other. A transparent dielectric film is provided to cover the electrodes, and a switching signal is output when the capacitance between the paired electrodes exceeds a predetermined value. It is characterized in that it is configured to include a signal generating circuit that generates a signal.

(Function) The structure is such that shapes and electrodes are formed on the substrate, a transparent dielectric film is provided to cover the electrodes, and a signal generation circuit is provided to output a switching signal, so a switching function can be added to the ornament. Therefore, the number of parts is reduced compared to the case where separate ornament and switch devices are used.

(Embodiment) Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 to 7.

1 and 2, reference numeral 1 denotes a rectangular case as a whole, and a rectangular opening window portion 1a is formed approximately at the center of the upper surface of the case. 2 is the bottom plate,
This is designed to close the bottom opening of the case 1. 3 is a rectangular board to be described later, which is attached to the case 1 so as to face the opening window 1a of the case 1.
It is located inside. 4 is a circuit board disposed along the bottom surface of the board 3, on which electronic components 5 are mounted.
is installed. Further, 6 is a connection line that connects the board 3 and the circuit board 4. Reference numeral 7 denotes a push-button switch, which is arranged so that its operator 7a is inserted into an insertion hole 1b formed at the left end of the case 1 and exposed.

Now, the substrate 3 will be explained in detail with reference to FIGS. 3 to 6. In FIG. 4, 8 is a rectangular decorative board, on the surface of which ornamental characters 9 (for example, "TOKAIRIKA") are formed. Reference numeral 10 denotes a rectangular transparent substrate whose longitudinal dimension is larger than that of the decorative board 8, and transparent electrode pairs 11 and 1 are arranged on the upper surface of the substrate at a predetermined distance from each other.
2 and 13 are formed by vacuum deposition or the like.
The transparent electrode pair 11 corresponds to "TO" of the ornament character 9, the transparent electrode pair 12 corresponds to "KAI" of the ornament character 9, and the transparent electrode pair 13 corresponds to "KAI" of the ornament character 9.
corresponds to ornament character 9 "RIKA". Here, the transparent electrode pair 11 is configured as a comb-shaped electrode in which a pair of electrodes 11a and 11b are shaped like the letters "TO" and are spaced apart from each other by a predetermined distance, as shown in FIG. Furthermore, the transparent electrode pair 12, 13 is also configured in the same manner. A thin transparent dielectric film 14 is provided on the upper surface of the transparent substrate 10 so as to cover these electrodes 11, 12, and 13. The substrate 3 is constructed by attaching a decorative plate 8 to the lower surface of such a transparent substrate 10 (see FIG. 5).

Next, the electrical configuration will be explained according to FIG.

Reference numeral 15 denotes a timer circuit, which outputs a timer signal Sa for a predetermined period of time when the contacts (a and b) of the push button switch 6 are turned on. 16
is a signal generation circuit, which is switched to an operating state only while receiving the timer signal Sa from the timer circuit 15, and in that operating state, the electrostatic charge between the transparent electrode pairs 11, 12, and 13 is reduced. When the capacitance exceeds a predetermined value, each transparent electrode pair 11,
A switching signal Sb that can specify 12 and 13 is output. Here, the case where the capacitance between each transparent electrode pair 11, 12, 13 exceeds a predetermined value means that a finger or the like is touched on the dielectric film corresponding to each transparent electrode pair 11, 12, 13. In this case, each transparent electrode pair 11,1
2 and 13 are configured to function as so-called touch switches. The thus constructed vehicle ornament 17 with a switch function is attached to a predetermined position such as the trunk, bonnet, or door. Reference numeral 18 denotes a decoding circuit which decodes the input pattern of the switching signal Sb from the signal generating circuit 16, and when it matches a predetermined recited code pattern stored in advance, it decodes the input pattern of the switching signal Sb from the signal generation circuit 16, and when it matches a predetermined recited code pattern stored in advance, it decodes the input pattern of the switching signal Sb from the signal generating circuit 16, and when the input pattern matches a predetermined recited code pattern stored in advance, It is now possible to release the lock.

According to this embodiment having such a configuration, the ornamental characters 9 are formed on the surface of the substrate 3, and the transparent electrode pairs 11, 12, 13 corresponding to the ornamental characters 9 are formed on the substrate 3. vs 1
A dielectric film 14 is provided to cover the transparent electrode pairs 10, 11, and 13, and a switching signal is generated when the capacitance between the transparent electrode pairs 10, 11, and 12 exceeds a predetermined value.
Since it is configured to include a signal generation circuit 16 that outputs Sb, unlike the conventional structure, the ornament and the switch function can be integrated, which reduces the number of parts and improves installation workability.

In the above embodiment, the transparent electrode pair 1 is provided on the substrate 3.
Although electrodes 1, 12, and 13 are formed, opaque electrodes may be formed instead. In this case, since the electrodes are shaped like the ornamental characters 9, there is no risk of spoiling the appearance.

FIG. 8 shows a second embodiment of the present invention.
The difference from the first embodiment is that the transparent electrode pair 1
Instead of electrodes 1, 12, and 13, pairs of comb-like transparent electrodes 19, 20, and 21 each having a generally rectangular shape are formed corresponding to the ornamental characters 9. Also in this second embodiment,
The same effects as in the first embodiment can be obtained.

In addition, the present invention is not limited to the above-mentioned embodiments; for example, the number of paired electrodes may be set as appropriate.

[Effects of the invention] As is clear from the above description, the present invention forms a shape on the surface of a substrate, and also forms a pair of electrodes on the substrate so as to correspond to the shape and to be spaced apart from each other by a predetermined distance. a transparent dielectric film to cover the electrodes, and a signal generation circuit that outputs a switching signal when the capacitance between the pair of electrodes exceeds a predetermined value. Therefore, by integrating the ornament and the switch device, the number of parts can be reduced.
This has the excellent effect of improving installation workability.
