Electronic speed measuring device for a beach buggy

摘要

An electronic speed-measuring device for a beach buggy includes a magnetic member and a sensor. The magnetic member is fixed on the chain wheel driven by an engine of a beach buggy so the magnetic member rotates together with the chain wheel. The sensor is provided on an unmovable portion of a beach buggy, facing the moving track of the magnetic member and maintaining a proper distance from them. The sensor can detect the function of the magnetic member and transmit immediate digital data (signals) to a speedometer so that the speed of a beach bugay shown on the speedometer is extremely precise, achieving practical effect of installing with quickness and detecting speed with precision.
