Bicycle power generating device and complete lamp and bell

Abstract

The invention provides the bicycle dynamoelectric equipment including several magnets, electricity supply coil group, accumulator and the dynamo, the bell, characterized in that several magnets via the magnetizer circling the axle are fixed on the same circle of the rung equidistantly, the polarity of the neighbor magnet reverses, the electrical output coil group is fixed on the vehicle frame corresponding to the magnet, the clearance between the electrical output coil group and the magnet is 5-7mm, the output end of he electrical output coil group connects accumulator via the commutating bridge, the accumulator connects the dynamo and the bell via lock linkage switch. Because of several magnets wholly fixed on the same circle of the rung via magnetizer, there are clearance between the magnet and electrical output coil group and the integrate magnet loop is formed, so it is assured that the turn of the rung produces the sufficient current and no friction, we mounts a lock linkage switch controlled by the lock of the vehicle in the output electrical loop of the accumulator, so locking the vehicle can shut the power supply of the dynamo and the bell, contrarily it can turn the power supply circuit, so it has many merits: without superfluity work, saving the electrical energy, using conveniently and choiceness performance.

Description

Technical field [0001] The invention provides a bicycle power generating device and matching lamps and bells, in particular to a bicycle power generating device and the matching lamps and bells. Background technique [0002] my country is a kingdom of bicycles, and there are many hidden dangers when driving at night due to poor road conditions and no lights. In view of the above problems, "motorized lamps" have been popular on bicycles, but the disadvantages in practical applications are: the bicycles equipped with "motorized lamps" have large resistance when driving, are not energy-saving, have low power generation efficiency, loud noise, and complex structures. Afraid of mud, afraid of water, easy to damage, although it has been on the market for decades, due to the above reasons, it has not been popularized and applied in the bicycle industry so far.

Problems solved by technology

In view of the above problems, "motorized lamps" have been popular on bicycles, but the disadvantages in practical applications are: the bicycles equipped with "motorized lamps" have large resistance when driving, are not energy-saving, have low power generation efficiency, loud noise, and complex structures. Afraid of mud and water, easy to damage, although it has appeared in the market for decades, due to the above reasons, it has not been popularized and applied in the bicycle industry so far

However, in practical application, there are the following defects: 1. Since multiple magnets are separately fixed on the spokes of the car with a large distance apart, a complete magnetic circuit and flux will not be formed, and the magnetic force lines are relatively weak. Although the magnetic lines of force can generate weak currents, they cannot be used as a generator to supply power to electrical appliances; 2. The magnet is relatively close to the edge of the wheel, so that the magnet will absorb the iron on the road during driving, and over time, the magnet will be filled The gap between the stator winding and the stator winding causes friction between the two, no longer "wear-free" and labor-saving, and the rider feels very strenuous; 3. Since multiple magnets are not fixed on the spokes as a whole but individually, it is easy to Make the spokes of the car different in tightness, cause the rim to deform, and cause wear between the magnet and the stator winding

4. The magnets exposed on the spokes of the car will also decline in performance after a long time, and its practical performance needs to be further improved

[0004] In view of various reasons, although there are a complete range of bicycles and a dazzling array of varieties, no matter whether it is an imported product or a domestic product, there is no reliable and labor-saving bicycle power generation device, and of course there are no lights and bells used in conjunction with it.
