Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of a remote control device for a vehicle.

[Conventional technology]

A conventional remote control device that operates a lock actuator that unlocks and rotates a door lock by an optical signal such as infrared rays from a transmitter operated outside the vehicle without using a key is It was placed in the ceiling of the vehicle, near the room mirror attachment, or on the dash panel.

[Problems to be solved by the invention]

That is, in the remote control device having the above-described conventional configuration, the light receiving portion is disposed at a position largely apart from the conventionally known keyhole disposed in the door panel. Therefore, when operating the door lock using the remote control device. Had to point the transmitter in a direction far away from the keyhole position, which was uncomfortable for a user who was used to using a conventional key.

Then, this invention aims at providing the remote control device for vehicles which does not give a user a feeling of strangeness and enables more reliable reception.

[Constitution of device]

The present invention was devised in view of the above, and includes an optical sensor that receives an infrared signal from a transmitter, a lock actuator that activates a lock mechanism that locks or unlocks an opening / closing portion of a vehicle body, the optical sensor, and the lock actuator. A remote control device for a vehicle, comprising a control mechanism connected to and for comparing the signal received by the sensor with a preset value and activating the actuator if they match, the optical sensor It is attached to a light guide section arranged in the vicinity of an opening for disposing a keyhole provided in the vehicle body,
The light guide portion is made of a transparent member, and further, the light guide portion has a ring portion in the center of which an opening whose inner peripheral diameter increases toward the outside of the vehicle body is provided. Is exposed at the boundary between the opening for disposing the keyhole and the keyhole.

[Action]

According to the configuration of the present invention, since the light guide portion including the optical sensor is arranged in the vicinity of the conventionally known opening for mounting the keyhole of the vehicle body, it is possible to operate the transmitter in the direction of the opening. For example, the remote control device operates reliably, and there is no discomfort to the user.

Furthermore, since the diameter of the inner peripheral surface of the exposed ring portion increases toward the outside of the vehicle body, which is a so-called tapered shape, it is possible to increase the light receiving area for an optical signal from the side of the vehicle body. As the receiving sensitivity improves,
Even if the optical signal from the transmitter is incident from an oblique direction, the reception is surely performed.

Furthermore, since the exposed part is located one step deeper than the outer surface of the vehicle body, noise signals such as sun rays are hard to enter and the exposed part is hard to be dirty, and the remote device reliably picks up the signal from the transmitter to ensure operation. .

The light ring 22 is made of a transparent material such as acrylic resin,
As shown in FIGS. 5 (a) to 5 (c), a ring portion 26 provided with an opening 24 having an inner peripheral portion 25 formed in a tapered shape (mortar shape) in the center, and the ring portion 26. With respect to the column portion 28, which is provided in a substantially vertical direction, and the recess portion 30 provided at the end of the column portion 28.
And a flat plate portion 32 having a photo sensor 34 as an optical sensor.

In the state where the optical ring 22 is mounted on the door opening / closing portion 6, the inner peripheral portion 25 of the opening 24 of the ring portion 26 forms the opening 7 of the base portion 8 and the keyhole 16 as shown in FIG. It is configured to be exposed at the boundary.

FIG. 6 shows an outline of a remote control device to which the configuration of this embodiment is applied.

The transmitter 36 has a photodiode 38 therein and is configured to output a predetermined infrared signal S when a switch (not shown) is operated. The receiver 40 has a photosensor 34 attached to the optical ring 22, an amplifier (not shown), etc., and is connected to a control mechanism 42 having a comparison circuit etc. for comparing an input signal with a preset value. The mechanism 42 is connected to a lock actuator 44 that operates a conventionally known lock mechanism.

In the structure of this embodiment, when the user directs the transmitter 36 toward the keyhole 16 and operates a switch (not shown), the infrared signal S is transmitted to the inner peripheral portion 25 and the pillar portion 2 of the ring portion 26 of the optical ring 22.
It is transmitted to the photo sensor 34 through the 8 and the flat plate portion 32.
The signal S is converted into an electric signal by the sensor 34 and input to the control mechanism 42. When it is confirmed by the mechanism 42 that the signal S matches a preset value, a signal for operating the lock actuator 44 is output.

According to the above configuration, the optical ring 22 including the photo sensor 34 is provided.
Is arranged so as to be located in the vicinity of the keyhole position of the vehicle body, not only can the remote control device be operated reliably by operating the transmitter 36 in the direction of the keyhole, but also
This has the effect of not giving a strange feeling to the user.

In the above embodiment, the photosensor 34 is only attached to the flat plate portion of the optical ring, but as shown in FIGS. 7A to 7C, the light emitting diode 46 is attached to the flat plate portion 32 ', for example, the door 4 If a circuit is formed so that the diode 46 emits light when the handle 12 is pulled while the lock is locked, it can be used as a keyhole illumination position useful when unlocking the door in dark places. You can

Can be transmitted to.

Further, in the above embodiment, the inner peripheral portion 25 of the opening 24 formed in the ring portion 26 of the optical ring 22 is formed into a flat taper shape (or a mortar shape), but as shown in FIG. By forming the inner peripheral portion 25 'of the ring portion 26' of the ring 22 'in the shape of a convex lens, it is possible to increase the surface area of the inner peripheral portion 25' and improve the light converging property.

In the above embodiment, the key cylinder 18 is provided on the door opening / closing section 6.
However, if it is not necessary to lock or unlock the lock mechanism with a key, the part where the keyhole is originally located may be covered with an iron plate or the like without being attached.
