Description

Technical Field

[0001] The present invention relates to the technical field of wireless remote control devices, and more particularly to a remote controller that generates electricity by mechanical pressing. Background Art

[0002] Wireless remote controllers on the existing market generally use infrared rays, radio frequency or other radio communication methods to achieve the function of sending remote control signals. However, for the current infrared remote controllers on the market, due to high power consumption, dry batteries or button batteries need to be installed to provide power. There are also radio frequency remote controllers with batteries, but the power supply needs to be frequently replaced, which is not very convenient to use. Some mechanical pressing power generation radio frequency remote controllers, although solving the power supply problem, the existing mechanical pressing power generation remote controllers on the market mainly use 433Mhz radio frequency signals. The radio frequency signals in this frequency band consume relatively large power, and the transmitted remote control signals are all analog signals. Therefore, it is relatively difficult to match the remote controller with the remote control device. On the other hand, the remote control distance is also limited, generally not exceeding 10m, and an external large-size antenna needs to be used to enhance the transmission power, resulting in a large size of the mechanical power generation device.
