Electromagnetic Mechanical Range Extender for Electric Bicycle

Abstract

In the electromagnetic mechanical range extension device for electric bicycles, a ring of ratchet teeth is formed on the inner wall of the retaining ring of the mounting plate, and the bottom plate of the mounting plate is formed with a mounting plate post and a convex ring of the mounting plate, and the bottom plate of the mounting plate is fixed on the hub of the electric bicycle by screws; The structure is that an inner disk outer retaining ring and an inner disk inner retaining ring are formed on the inner disk bottom plate, the outer ring of the bearing is fixed on the inner disk inner retaining ring, the inner ring of the bearing is fixed on the shaft sleeve, and the shaft sleeve is fixed on the rotating shaft of the electric bicycle wheel hub. The electromagnetic coil is inserted between the outer retaining ring of the inner disk and the inner retaining ring of the inner disk, the installation disk insert is inserted into the preset through hole on the friction plate, the eddy current reed is placed between the outer disk and the inner disk, and the upper end of the eddy current reed It is fixed on the outer disc, and the lower end of the eddy current reed is fixed on the inner disc. The energy stored by the reed is directly released to the electric bicycle when it starts again, and the energy saving effect is remarkable. Tests show that the present invention can increase the range of electric bicycles used in cities by more than 70%.

Description

Technical field: [0001] The invention relates to the technical field of electric bicycles, and more particularly to an energy-saving range extension device on an electric bicycle. Background technique: [0002] Existing range extension devices for electric bicycles and motorcycles generally convert excess energy of electric bicycles or motorcycles when braking or descending slopes into electrical energy and store them, and then use them for electric bicycles or motorcycles. The disadvantage is that converting mechanical energy into electrical energy will lose part of the energy, so its energy-saving incremental effect is limited. Generally, electric bicycles that use range-extending devices can only increase the travel of electric bicycles by about 20%. [0003] CN201380760Y discloses an electric vehicle braking energy recovery and utilization device. Its energy storage structure is relatively complicated. The energy stored by the spring needs to be stored for many times and...
