Abstract
Description
Technical Field
[0001] This utility model relates to the field of wireless remote control technology, and more specifically, to a remote control that generates electricity by mechanical pressing. Background Technology
[0002] Currently available wireless remote controls generally use infrared, radio frequency (RF), or other wireless communication methods to transmit remote control signals. However, infrared remote controls on the market currently require dry cell batteries or button batteries for power due to their high power consumption. RF remote controls with built-in batteries also exist, but require frequent power supply replacements, making them inconvenient to use. While some mechanically press-to-generate RF remote controls solve the power issue, existing mechanically press-to-generate remote controls on the market mainly use 433MHz RF signals. RF signals in this frequency band consume a lot of power, and the transmitted remote control signals are all analog, making pairing the remote control with the device difficult. Furthermore, the remote control distance is limited, generally not exceeding 10 meters, and requires a large external antenna to enhance transmission power, resulting in a large mechanical generator.
[0003] Therefore, there is an urgent need in this field for a mechanical press-to-generate remote control that does not require an external power supply, is small in size, and has good remote control reliability, in order to solve the problems existing in the prior art. Utility Model Content
