Description

Piezo button remote control

The invention relates to an environmentally friendly battery-free piezoelectric button, in particular to a remote controller with a piezoelectric button.

Traditional batteries contain mercury, which is widely known for its environmental hazards. It is imperative to study more environmentally friendly and convenient new energy devices to replace traditional batteries. Piezoelectric button device is one of the energy devices. It has the advantages of simple structure, no heat, no electromagnetic interference, easy processing and realization of miniaturization and integration in structure. Therefore, piezoelectric power generation technology has become a new one. Research area. The first picture is a schematic diagram of the button, which cannot be supplemented by pressing to generate additional power, and there is still room for improvement.

Therefore, how to eliminate the above problems is the technical difficulty point that the creators of the case want to solve.

In view of the above-mentioned deficiencies, the inventors of the present invention have collected relevant materials, and through multi-party evaluation and consideration, and accumulated many years of experience in this field, through continuous trial and modification, the invention patents were designed.

In order to solve the problems of the prior art, the present invention combines a piezoelectric button technology with a remote controller to propose a piezoelectric button type infrared remote controller. The button of the remote control is replaced by a piezoelectric button that converts the mechanical energy of the button when pressed into the electrical energy required by the internal circuitry. After pressing the piezoelectric button, power is generated, and the code signal of the remote controller is transmitted through the infrared light emitting diode to achieve the purpose of remote control. The piezoelectric button of this case is selected from ceramic barium titanate (PZT), single crystal quartz (crystal), tourmaline, Rhodes salt, citrate, citrate, etc., or thin film zinc oxide. Any or all of (ZnO) And adding excipients such as rubber particles, and then processing into piezoelectric buttons, the piezoelectric button type can also be embedded in the elastic material (such as rubber).

Referring to the second to third figures, which are schematic diagrams (1) to (2) of the present invention, the first combination of the conventional button 10 and the piezoelectric material 20 (as shown in the second figure) becomes The piezoelectric button 30 as shown in the third figure, wherein the piezoelectric material 20 of the present invention is selected from the group consisting of ceramic barium titanate (PZT), single crystal quartz (crystal), tourmaline, Rhodes salt, and tannic acid. Salt, citrate, etc., or any of the zinc oxide (ZnO) of the film type, since the piezoelectric material 20 is different from the elasticity of the conventional conventional button 10, it is necessary to add an excipient such as rubber particles and then process it. The piezoelectric button 30 can be used to have an elastic feel like a conventional remote control, and the piezoelectric button 30 can also be embedded in the conventional button 10 with the piezoelectric material 20. The above piezoelectricity means that when an object is subjected to a mechanical stress, a relative displacement is generated between the positive and negative charge centers therein to generate a relative electric field. This phenomenon is called a positive piezoelectric effect. Conversely, when an object is subjected to an electric field, it will also deform the material and change in size. This phenomenon is called the inverse piezoelectric effect. These two phenomena are called piezoelectricity. For example, the quartz wafer itself is a piezoelectric material, and an external voltage is applied to both sides of the wafer to generate an electric field. Due to the mechanical and electrical coupling of the piezoelectric material itself, the crystal itself is mechanically deformed, and the crystal is cut. The surface is subjected to mechanical stress, and a potential difference is generated between the opposite faces of the crystal. When an alternating voltage is applied to the upper and lower sides of the piezoelectric crystal, the electrode is vapor-deposited on the xz plane of the y-cut quartz plate, and the oscillating wafer oscillation can be generated. The frequency of the vibration varies depending on the crystal, and the quartz crystal cutting piece is more Thin, the more difficult the cutting technology, but the higher the resonant frequency, but quartz is only an example, not limited The materials used in this case.

Therefore, the piezoelectric button 30 can convert the mechanical energy when the piezoelectric button 30 is pressed into the electric energy required for the internal circuit of the remote controller. When the piezoelectric button 30 is pressed, power is generated immediately, and the coded signal of the remote controller is transmitted through the infrared light emitting diode to achieve the purpose of remote control.

Please refer to the fourth and fifth figures, which are schematic diagrams showing the combined state of the present invention and the state of use of the present invention.

As shown in the fourth figure, the remote controller is combined with the piezoelectric button 30 to become a remote controller 40 having a piezoelectric button. The fifth figure shows a state of use of the remote controller 40 having a piezoelectric button. When the piezoelectric button 30 is pressed, the button body is deformed to force the piezoelectric material 20 to generate electric power (as shown in the sixth figure). ).

In summary, the present invention can achieve its efficacy and purpose when used, so the invention is excellent in practicality, and is in accordance with the application requirements of the invention patent, and the application is submitted according to law, and the audit committee is expected to grant the creation as soon as possible. In order to protect the hard work of the inventor, if there is any doubt in the audit committee of the bureau, please do not hesitate to give instructions, the inventor will try his best to cooperate, and feel really good.
