AI Technical Summary

Problems solved by technology

Because this method must have complex digital circuits, and even digital processing devices such as single-chip microcomputers, the cost is relatively high, and the complex circuits are also prone to failures, which may cause failures in speed measurement and speed limit, or even fail.
Therefore, people are in urgent need of a low-cost, simple-in-structure speed-limiting device for electric vehicles, but there is no such device at present.

Abstract

The invention discloses an electric bicycle overspeed alarm, and belongs to a speed limiting device for transport. The electric bicycle overspeed alarm consists of a magnet installation block, a reed switch circuit, a music trigger chip, a power module and a speaker, wherein the magnet installation block is arranged on a spoke of a front wheel of an electric bicycle; the reed switch circuit, the power module, the music trigger chip and the speaker are fixedly arranged on a front fork of the electric bicycle; when the electric bicycle is overspeed, the speaker can give out continuous sound to prompt a rider. The device is simple in circuit, high in reliability and low in cost, and can give out continuous sound for prompt when the electric bicycle is overspeed.

Description

technical field [0001] The invention relates to an electric vehicle overspeed alarm, specifically a low-cost, simple-structured electric vehicle constructed by using magnets, reed switches, triggering music sheets, and speakers, and adopting the principle of centrifugal force of rotating objects. An overspeed alarm belongs to the field of speed governors of vehicles. Background technique [0002] Electric vehicles have become a very common means of transportation for people in cities. However, the disadvantage of electric vehicles is that they are silent and accelerate quickly, and people unconsciously put electric vehicles in high-speed danger in an instant. Although there are many speed limiters for electric vehicles, their principles are mostly based on components such as photoelectric cells or Hall devices, and then use complex digital processing circuits to collect speed signals from the wheels of electric vehicles and process them with microprocessors. After that, it...
