  However, since the conventional wireless remote control device relies exclusively on dry batteries for its power supply, there are cases where it becomes impossible to use due to running out of batteries, etc., and it is also difficult to manage the battery life, so it is very convenient to use. Had the problem of being bad.

  In order to solve this problem, a wireless remote control device having a self-power generation capability has been proposed. However, in this type of device having a conventional structure, the power to cover the transmission capability is charged. In order to achieve this, a great deal of labor is required, and this also has the problem of being unusable.

  The present invention was devised in view of the current situation, and an object of the present invention is to provide a wireless remote control device excellent in usability capable of obtaining sufficient transmission power with one action even without a power source. It is what.

  In order to achieve the above object, a wireless remote control device according to the present invention comprises a switch case having one end fixed in the switch case and the other end fixed to an intermediate portion of the support rod.

Therefore, it is possible to provide an excellent effect such that it can be provided at a low cost with few failures.

Moreover, in the invention according to claim 2, since the support rods to which the steel balls are fixed at both ends are formed of the spring material, it becomes possible to continue the vibration of the steel balls for a long time, with one action. Even if it exists, since sufficient electric power generation can be obtained and the operation stroke for electric power generation is short, the effect that the operation force of an operation switch can be made very light can be acquired.

  Hereinafter, the present invention will be described in detail based on Embodiment 1 of the present invention shown in the accompanying drawings.

  FIG. 1 shows a schematic configuration of a wireless remote control device 1 according to Embodiment 1 of the present invention.

The wireless remote control device 1 according to the first embodiment has a fixing rod 4 formed of a spring material having one end fixed in the switch case 2 and the other end fixed to an intermediate portion of the support rod 3, The steel balls 5 and 6 fixed to both ends of the support rod 3 formed of a spring material, and the piezoelectric power generation unit of the piezoelectric power generation device disposed within a range in which one of the steel balls 6 swings. 21, an operating body 9 having one end of a magnet 8 that can be attracted to the other steel ball 5 having magnetic absorption, and a fulcrum O that rotatably supports the other end of the operating body 9 as an operation switch section 9A. And the transmitter 10 that is operated by the electric power generated by the piezoelectric power generation unit 21.

In the switch case 2, as shown in FIG. 2, the piezoelectric element power generation unit 21 and the rectifier circuit 22 that constitute the piezoelectric power generation device are disposed. In addition, the transmission circuit unit 16 of the transmitter 10 includes a control unit 23, a transmission unit 24, and an antenna 25.

  The piezoelectric elements constituting the piezoelectric power generation unit 21 are held in a flexible structure by a cushion material 29. In this Example 1, in this Example 1, two PZT-type piezoelectric piezoelectric ceramic plates were joined so that their polarizations were opposite to each other, and the power generation configuration was connected in series to cancel the polarization. It is configured to prevent power generation and improve power generation performance.

  This piezoelectric ceramic plate is made of a titanium zirconate-based material, and as the cushion material 29, a synthetic resin material, a rubber material, or a soft material in which these are formed in a sponge shape can be used. For this, foamed polyethylene is preferred. Furthermore, in Example 1, the steel balls 5 and 6 are made of tungsten, iron, or the like that is heavy and has high power generation efficiency so as not to destroy the piezoelectric element, and the steel ball collision surface portion of the piezoelectric element is coated with a protector. In this case, a hard metal such as phosphor bronze or stainless steel excellent in workability or a synthetic resin can be used.

Further, this piezoelectric element is partially bonded to the central portion or both ends of the cushion material 29 with an adhesive. Of course, you may fix by fixing means other than an adhesive agent.

The rectifier circuit 22 is a circuit that rectifies the AC power output from the piezoelectric element power generation unit 21 to generate a pulsating flow, and a full-wave rectifier circuit is formed by a required number of diodes.

When power is supplied by a method to be described later, the operation is started and the signal switch means is turned ON, and data for transmission is also transmitted. Send to signal generation means.

The data for transmission includes at least various ID data given to the wireless remote control device.

The signal generating means converts the data for transmission received from the communication control means into a predetermined radio signal and transmits it from the antenna 25. Of course, in the first embodiment, when the wireless remote control device is configured to include a battery, after the communication control unit finishes sending all data necessary for transmission to the signal generation unit, It is desirable to control the communication control means to operate and stop the discharge.

  The power generation unit 15 configured as described above rectifies the generated current by the rectifier circuit 22 to operate the transmission circuit unit 16, and the transmission circuit unit 16 generates radio waves having various frequencies (various operation selection modes). Signal) is transmitted to a receiver 31 such as a home appliance such as a television or a remote controller.

In the first embodiment, when the piezoelectric element receives stress and generates power, the receiver 31 is activated almost simultaneously to transmit a signal. However, the present invention is not limited to this. However, when it is possible to transmit a more stable radio wave signal, the wireless remote control device may be operated to store the excess current consumed in the battery as needed.

In this case, although not particularly illustrated, a charging unit comprising a capacitor for charging the pulsating flow obtained by the rectifier circuit 22 as a direct current, and the charging amount of the charging unit are intermittently determined in accordance with the power generation timing of the piezoelectric element.
