Signal transmitter-receiver apparatus
View Patent ↗To provide a signal transmitter-receiver apparatus having simple structure and which can prevent receiving sensitivity reduction of wirelessly transmitted signal using an existing component. A signal transmitter-receiver apparatus includes a first electric wire having one end connected to an electronic device provided at a vehicle sliding seat, a second electric wire wired at a vehicle body side, a signal transmitter connected to another end of the first electric wire, a signal receiver connected to an end of the second electric wire for receiving signal wirelessly transmitted from the signal transmitter, and a protector. The signal transmitter and the signal receiver are disposed in the rail. The signal transmitter is fixed to an upper rail via the protector. The signal receiver is fixed to one end portion of the rail. The signal transmitter and the signal receiver are arranged opposed to each other in a straight line.
1. A signal transmitter-receiver apparatus, comprising:
a first electric wire having one end connected to an electronic device provided at a vehicle sliding seat;
a second electric wire wired at a vehicle body side;
a signal transmitter connected to another end of the first electric wire;
a signal receiver connected to an end of the second electric wire and configured to receive a signal wirelessly transmitted from the signal transmitter;
wherein the signal transmitter and the signal receiver are disposed in a rail disposed below the sliding seat,
wherein the signal transmitter is fixed to an upper rail directly or via another member, the upper rail being attached to a lower face of the sliding seat and being slidably attached to the rail,
wherein the signal receiver is fixed to one end portion of the rail, and
wherein the signal transmitter and the signal receiver are arranged opposed to each other in a straight line.
2. The signal transmitter-receiver apparatus according to claim 1 , further comprising a protector made of synthetic resin, wherein the protector includes:
a tube portion through which the first electric wire is passed;
a holding portion holding the signal transmitter; and
a bracket configured to be attached to the upper rail.
3. The signal transmitter-receiver apparatus according to claim 2 , further comprising:
a photovoltaic element connected to another end of the first electric wire; and
a light emitting element connected to an end of the second electric wire and configured to radiate light to the photovoltaic element.
4. The signal transmitter-receiver apparatus according to claim 3 , wherein the signal transmitter is activated by a battery having charge function or by electromotive force of the photovoltaic element, and wherein the battery is charged by electromotive force of the photovoltaic element.
5. The signal transmitter-receiver apparatus according to claim 1 , further comprising:
a photovoltaic element connected to another end of the first electric wire; and
a light emitting element connected to an end of the second electric wire and configured to radiate light to the photovoltaic element.
6. The signal transmitter-receiver apparatus according to claim 5 , wherein the signal transmitter is activated by a battery having charge function or by electromotive force of the photovoltaic element, and wherein the battery is charged by electromotive force of the photovoltaic element.
