Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 8, a bicycle pedal includes a pedal 1, a rotation shaft 2, a first magnetic member 3, a second magnetic member 4, a conductive coil 5, and a light emitting unit 6; the pedal 1 is internally provided with a containing cavity 10, the pedal 1 is rotationally connected with the rotating shaft 2, the rotating shaft 2 is also provided with a rotating cavity 20 communicated with the containing cavity 10, and the first magnetic part 3 and the second magnetic part 4 are opposite in polarity and oppositely arranged in the rotating cavity 20; the light-emitting unit 6 is installed on the pedal 1, the conductive coil 5 is fixedly installed in the accommodating cavity 10, two ends of the conductive coil 5 are respectively electrically connected with the anode and the cathode of the light-emitting unit 6, and one side of the conductive coil 5 also extends into the rotating cavity 20 and is located between the first magnetic piece 3 and the second magnetic piece 4.

Specifically, when a bicycle with the bicycle pedal runs, a rider treads the pedal 1, so that the pedal 1 and the rotating shaft 2 rotate relatively, and meanwhile, the conductive coil 5 arranged on the pedal 1 also rotates relative to the first magnetic piece 3 and the second magnetic piece 4 arranged in the rotating shaft 2, so that the conductive coil 5 cuts magnetic induction lines between the first magnetic piece 3 and the second magnetic piece 4 and generates current, and the power is supplied to the light-emitting unit 6, and the light-emitting unit 6 plays a role in warning. In the process, because the conductive coil 5 is not in contact with the first magnetic part 3 and the second magnetic part 4, redundant friction cannot be generated, and a rider does not need to spend more labor to step on compared with a common bicycle when riding the bicycle with the bicycle pedal. The current generated by the conductive coil 5 directly has the function of the light-emitting unit 6, and after the conductive coil 5 and the magnetic part stop rotating relatively, the generated current is interrupted, the light-emitting unit 6 can be directly closed, the process that a rider manually opens a switch is omitted, and the use is more convenient.

Further, in order that the light emitting unit 6 can still be kept bright for a period of time after the rider stops pedaling the pedal 1, the bicycle pedal further comprises a control board 7, the control board 7 is installed in the accommodating cavity 10, a battery 71 and a rectifier 72 are arranged on the control board 7, two ends of the conductive coil 5 are connected to the control board 7 and connected with the rectifier 72, the rectifier 72 is electrically connected with the battery 71, and the light emitting unit 6 is electrically connected with the battery 71. The electric current that conductive coil 5 produced stores in battery 71 at first, and after footboard 1 and pivot 2 stopped relative rotation, the electric energy of piling up in the battery 71 still can be for luminescence unit 6 energy supply period to guarantee to ride passerby when riding, stop trampling footboard 1 and the in-process that slides, luminescence unit 6 continues the operation, prevents to slide the in-process and can't play the warning effect because of the extinction of luminescence unit 6. In the present invention, since the foot of the rider always steps on the pedal 1, the pedal 1 is always in a relatively horizontal state, that is, the conductive coil 5 is relatively stationary, and the rotating magnetic field is formed by the first magnetic member 3 and the second magnetic member 4, the current generated by the conductive coil 5 in the magnetic field is an alternating current, and since the conductive coil 5 is relatively stationary, a commutator cannot be applied to convert the current property, in the embodiment of the present invention, the alternating current generated by the conductive coil 5 is converted into a direct current by using the rectifier 72, so that the battery 71 can be charged.

Furthermore, the control board 7 is further provided with a positioning unit 73, and the positioning unit 73 is electrically connected with the battery 71. Since the concealing property of the bicycle pedal is good, and a normal bicycle can not be separated from the pedal, if the bicycle with the bicycle pedal is stolen, the actual property of the bicycle pedal is difficult to be found by a thief, so that once the thief rides the bicycle, the actual owner can track the position of the stolen bicycle through the positioning unit 73 and timely retrieve the stolen bicycle.

Furthermore, because the conductive coil 5 is relatively slender, in order to reduce the shaking degree of the conductive coil 5, the bicycle pedal further comprises a fixing piece 8, the fixing piece 8 is sleeved on the conductive coil 5, and the fixing piece 8 is detachably connected in the accommodating cavity 10. The fixing piece 8 is made of insulating materials, and the stability of the conductive coil 5 is enhanced through the fixing piece 8.

It is well known that the magnitude of the current generated by a coil in a magnetic field is related to its rotational speed. When the bicycle is ridden, the relative rotating speed of the pedal 1 and the rotating shaft 2 is slow, and the current generated by the conductive coil 5 is also small, so that the problem of insufficient energy supply can be caused. Therefore, in the embodiment of the present invention, the bicycle pedal further comprises a rotating tube 9, a ring gear a1 and a differential gear a2, the pedal 1 is further provided with a driving part 11, and the driving part 11 is sleeved on the rotating shaft 2; the rotary drum 9 is rotatably arranged in the rotary cavity 20, a power generation cavity 90 is arranged in the rotary drum 9, the first magnetic part 3 and the second magnetic part 4 are arranged in the power generation cavity 90, and the conductive coil 5 can extend into the power generation cavity 90; the ring gear a1 is installed on the driving part 11, the rotating shaft 2 is also provided with an opening 21 for communicating the rotating cavity 20 with the outside, the differential gear a2 is rotatably installed in the rotating cavity 20, and one side of the differential gear a2 can also extend out of the opening 21 and is meshed with the ring gear a 1; the drum 9 is further provided with a transmission gear 91, and the transmission gear 91 is further in driving connection with a differential gear a 2.

Wherein the reference circle radius of the differential gear a2 is smaller than the reference circle radius of the ring gear a1, so that the rotation speed of the differential gear a2 is greater than the rotation speed of the ring gear a 1. When the pedal 1 rotates relative to the rotating shaft 2, the ring gear a1 mounted on the driving portion 11 also rotates relative to the rotating shaft 2, so as to rotate the differential gear a2 and increase the speed of the differential gear a2, and further rotate the drum 9 and increase the speed of the drum 9. If the rotating shaft 2 is taken as a reference, the rotating direction of the rotating drum 9 is opposite to the rotating direction of the pedal 1, so that the relative speed between the rotating drum 9 and the pedal 1 is further increased, the rotating speed of the conductive coil 5 relative to a magnetic field is increased, namely, the current generated by the conductive coil 5 is increased, and the normal energy supply of each component is ensured.
