ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a lever bar activation detecting structure used for detecting the braking operation of an electric two-wheel vehicle, especially for an electric bicycle. The detecting structure has less components and can be easily assembled. Moreover, the structure has excellent waterproof effect and is able to accurately detect the braking signal.
Many kinds of electric bicycles have been developed. However, these electric bicycles are still in a tested stage. Many parts of the electric bicycle still need to be improved for achieving better function. For example, the braking operation detecting switch of the existent electric bicycle is composed of numerous complicated components which are interconnected by mechanical measures. It is troublesome to assemble these components and thus the manufacturing cost is high. The most serious shortcoming of such switch is that it has very poor waterproof effect Unless a waterproof cover is added to the switch, the switch will have almost zero waterproof effect. This is especially critical to a light weight electric bicycle which requires that the respective parts be light and easily assembled and disassembled.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a lever bar activation detecting structure used for detecting the braking operation of an electric two-wheel vehicle, especially for an electric bicycle. The detecting structure has less components and can be easily assembled. Moreover, the structure has excellent waterproof effect and is able to accurately detect the braking signal.
According to the above object, the lever bar activation detecting structure of the present invention includes a lever bar and a lever bar pivot seat with which the lever bar is pivotally connected. A magnet and a magnetic switch are respectively disposed on the lever bar and the pivot seat opposite to each other. When the lever bar is pressed, the magnet is moved relative to the magnetic switch so that the magnetic switch is energized to generate a signal for a controlling unit to detect the signal and turn on an indicating light. The magnet and magnetic switch have excellent waterproof effect and the structure can be easily assembled to lower cost.
The present invention can be best understood through the following description and accompanying drawings wherein:
