Abstract
A luminous pedal for a bicycle has a body with an I-like frame formed therein. An axle hole is longitudinally defined through the frame. An end cover is assembled at the front end and has a second hole in alignment with the axle hole. An axle has a head extending out from the second hole. A plurality of permanent magnets is circumferentially provided thereon and arranged N-pole by S-pole alternately. A coil seat with a coil is secured in the chamber. The permanent magnets are received in the coil seat. Two luminous plates is respectively secured at the side parts of the body and each have a plurality of luminous elements and electrically connected with the coil by a wire so that when the pedal is operated by a user, current is generated to light the luminous elements.
Claims18
A luminous pedal for a bicycle, the luminous pedal comprising:
- a body (10) formed with:
- a front end (11),
- a rear end (12),
- two opposite side parts (13), each connecting to the front end (11) and the rear end (12),
- a frame (15) formed therein,
- an axle hole (151) longitudinally defined through the frame (15),
- a chamber (111) defined at the front end (11),
- a first hole (121) defined at the rear end (12) and in alignment with the axle hole (151), and
- an end cover (16) assembled at the front end (11) and having a second hole (161) in alignment with the axle hole (151),
- wherein each side part (13) has a side wall (130), and a U-like bar (14) formed on the side wall (130) to define a channel (141);
- an axle (20) rotatably received in the axle hole (151), the axle (20) having:
- a head extending out from the second hole (161) with a plurality of permanent magnets (21) circumferentially provided thereon and arranged N-pole by S-pole alternately, and
- a coil seat (22) with a coil (223) secured in the chamber (111), the permanent magnets (21) being received in and radially spaced apart from the coil seat (22);
- and
- two luminous plates (30) respectively and detachably inserted in the channels (141) of the side parts (13) of the body (10), each having a plurality of first luminous elements (33) and electrically connected with the coil (223) by a wire (34),
- whereby when the pedal is operated, the coil (223) is rotated relative to the axle (20) to continuously cross magnetic fields of the stationary permanent magnets (21) and generates current to light the luminous elements (33).
