Description

The present invention relates to a remote control device that remotely controls a device or the like.

A remote controller device used as a key for unlocking a vehicle door or the like is provided with a switch for generating an electric signal by partially denting a rubber sheet or the like, for example. Further, when a plurality of such switches are provided in close proximity to each other, a technique for forming striped protrusions extending in parallel with each other on the surface of a film-like substrate is known in order to prevent simultaneous pressing operations (for example,). See Patent Document 1.).

Jikkai Sho 58-55318

When forming striped protrusions on the surface of a film-like substrate as described above, it is not always easy to appropriately set the rigidity and dimensions of the substrate and striped protrusions to prevent inadvertent simultaneous pressing operations. is not it.

In view of the above points, it is an object of the present invention to make it possible to easily prevent inadvertent simultaneous pressing of a plurality of switches.

To achieve the above objectives
The present invention
It is a remote control device
Multiple switches provided on the circuit board and
An elastic sheet that covers the above multiple switches,
A spacer provided between the circuit board and the elastic sheet and arranged between the plurality of switches,
It is characterized by having.

As a result, since the portion of the elastic sheet that partitions each switch is supported by the spacer, the possibility that the other switch is pressed at the same time can be reduced.

According to the present invention, it is possible to easily prevent the simultaneous pressing of a plurality of switches.

It is a top view which shows the structure of the remote control device. It is a bottom view which shows the inner surface side of a rubber sheet. It is a perspective view which shows the relationship between a circuit board, a switch, and a spacer. FIG. 6 is a sectional view taken along line IV-IV of FIG. It is a VV cross-sectional view of FIG. FIG. 6 is a sectional view taken along line VI-VI of FIG.

Hereinafter, as an embodiment of the present invention, a remote control device used as a vehicle remote control key for unlocking a vehicle door or the like will be described.

As shown in FIG. 1, the remote controller 100 is configured such that the upper part 110 of the case body and the lower part 120 of the case body are overlapped with each other, and an elastic sheet 130 made of rubber and a circuit board 140 are provided inside the remote control device 100. There is. The circuit board 140 contains, for example, an electronic circuit that emits radio waves for remote control of unlocking a vehicle door, starting an engine, and the like, and is provided with, for example, three switches 141 to 143. The type of the switches 141 to 143 is not particularly limited, and for example, an electrode pattern may be formed on the circuit board 140 so that the switches 141 to 143 are made conductive by being pressed against the conductive rubber or the like.

The upper portion 110 of the case body is formed with a rectangular opening 110a, while the elastic sheet 130 is formed with a switch portion 130a protruding toward the outer surface so as to be exposed from the opening 110a. As shown in FIG. 2, on the inner surface side of the elastic sheet 130, a switch pressing convex portion 130d protruding corresponding to the positions of the switches 141 to 143 and a position different from the positions of the switches 141 to 143 are arranged. The support convex portion 130e is formed so as to come into contact with the circuit board 140 and prevent the elastic sheet 130 from being pushed in. Further, on the inner surface side of the elastic sheet 130, a recess 130b into which the spacer 150 is fitted and a periphery of the recess 130b so as to hold the spacer 150 provided between the elastic sheet 130 and the circuit board 140 are held. A edging portion 130c is formed so as to extend along the outer periphery of the spacer 150.

The spacer 150 is formed of, for example, a plastic or the like that is harder than the elastic sheet 130, and as shown in FIGS. 3 to 6, the spacer 150 is substantially inverted T in a plan view so as to partition the regions of the switches 141 to 143. It has a character-shaped T-shaped portion 150a and four leg portions 150b protruding toward the circuit board 140. By providing such a spacer 150, for example, when the user tries to press one of the two switches 141 and 142 shown in FIG. 4, even if the pressing position is slightly deviated, the elastic sheet Since the portion of the 130 that separates the two switches 141 and 142 is supported by the spacer 150, the possibility that the other switches 141 and 142 are pressed at the same time is reduced. Further, when the user tries to press one of these switches 141 and 142 and the switch 143 shown in FIG. 6, similarly, as shown in FIG. 5, the elasticity for partitioning these switches 141 to 143 is formed. Since the portion of the body sheet 130 is supported by the spacer 150, the possibility that the other switches 141 to 143 are pressed at the same time is also reduced.

As described above, by providing the spacer 150 between the elastic sheet 130 and the circuit board 140, it is possible to easily prevent the inadvertent simultaneous pressing of the plurality of switches 141 to 143. In particular, by providing the elastic sheet 130 and the spacer 150 as separate bodies, the degree of freedom in setting the hardness (elastic modulus) of both can be increased, so that the operational feeling such as tactile sensation can be improved and the above can be achieved. It is also relatively easy to prevent the switches 141 to 143 from being pressed at the same time.

Moreover, since it is easy to increase the arrangement density by bringing the switches 141 to 143 close to each other, it is possible to improve the degree of freedom in design.

Further, a recess 130b is formed in the elastic sheet 130 so that the spacer 150 can be fitted, and a edging portion 130c is formed around the recess 130b so as to protrude along the outer periphery of the spacer 150. By doing so, it becomes easy to hold the spacer 150 on the elastic sheet 130, so that the assembly workability can be easily improved. Further, it is possible to easily prevent the spacer 150 from collapsing.

Further, the spacer 150 does not necessarily have the leg portion 150b formed, but due to the formation of such a leg portion 150b, an electronic component or the like is formed between the leg portions 150b on the surface of the circuit board 140. It is easy to secure a space for arranging.

Further, by providing the support convex portion 130e that abuts on the circuit board 140, the inner surface side of the switch portion 130a of the elastic sheet 130 is reinforced, and excessive dents and subduction to the inner surface side of the case body upper portion 110 are prevented. Things can be done easily.

The spacer 150 may be attached to the circuit board 140 in advance, and then the elastic sheet 130 may be assembled.
