The embodiment of the application also discloses a bicycle. Referring to fig. 2 and 3, the bicycle includes the structure of the light-emitting pedal 2 described in the above embodiment, and further includes a frame 5, a battery 6, an electric energy processing device 7, and a light control switch 8. The battery 6, the electric energy processing device 7 and the light-operated switch 8 are all arranged on the frame 5. Battery 6 and warning light 3 carry out electric connection, and when warning light 3 lightened through first generator 4, can also supply power through battery 6 for 2 structures on the running-board also can light warning to warning light 3 when not rotating, further increase the security.

The electric energy processing device 7 is electrically connected with the battery 6 and the first generator 4 respectively, and electric energy emitted by the first generator 4 is stored in the battery 6 by using the electric energy processing device 7, so that the warning lamp 3 can be conveniently lightened when the pedal 2 is not stepped on subsequently. Specifically, the electric energy processing device 7 is an integrated circuit board, and the electric energy processing device 7 includes a power supply access end, a rectification filter module, a buck-boost module, a voltage stabilizing module and a power supply output end.

When the light is sufficient, the battery 6 no longer supplies power to the warning lamp 3, and the loss of the electric quantity of the battery 6 is reduced.

The frame 5 is also provided with a front wheel, a rear wheel 52, a state trigger switch 51, a worm 53, a second generator 54 and an electric cylinder 55, and the rear wheel 52 and the crank 1 rotate synchronously. The worm 53 is rotatably connected with the frame 5, the second generator 54 is slidably connected with the frame 5, and the electric cylinder 55 is fixedly connected with the frame 5. A crown gear 521 is provided on the rear wheel 52, and teeth that engage with the crown gear 521 are provided on the worm 53. When the rear wheel 52 rotates, the rear wheel 52 rotates the worm 53 via the crown gear 521. The second generator 54 is provided with a turbine 541 on an input shaft thereof, and the second generator 54 is fixed to a drive shaft of the electric cylinder 55.

In this embodiment, the electric cylinder 55 drives the worm gear 541 and the worm 53 of the second generator 54 at an initial state, so as to disconnect the connection between the rear wheel 52 and the second generator 54. When the electric cylinder 55 is started, the electric cylinder 55 drives the second generator 54 to move, so that the turbine 541 and the worm 53 can be in contact fit with each other, and the rear wheel 52 rotates to drive the second generator 54 to start. Specifically, the state trigger switch 51 is electrically connected to the battery 6 and the power supply terminal of the electric cylinder 55, and when the state trigger switch 51 is turned on, the electric cylinder 55 is started to control the second generator 54 to move, so that the turbine 541 and the worm 53 can be in contact and fit with each other, and the rear wheel 52 rotates to drive the second generator 54 to start. When the second generator 54 starts to operate, the battery 6 can be charged, and the riding resistance of the bicycle itself is increased, so that the bicycle is more easily stopped or decelerated, and the kinetic energy waste during the original braking is reduced.

The state trigger switch 51 is used to detect the state of the vehicle and to turn the switch on and off according to the vehicle state. When the bicycle is in a deceleration state and reaches a speed change threshold value or when the bicycle is in a downhill road section with an inclination larger than a preset value, the state trigger switch 51 is internally turned on. When the deceleration state of the bicycle does not reach the speed change threshold or the inclination angle of the downhill section where the bicycle is located is lower than the preset value, the state trigger switch 51 is turned off from on.

During level riding or uphill riding, the second generator 54 does not work, and the overall resistance of the bicycle is correspondingly smaller than the resistance of the original continuous charging. And when the speed is reduced or the downhill road section is used, the second generator 54 is controlled to be started so as to recover the kinetic energy and stop or reduce the speed of the bicycle.

Wherein, when the conductive moving part 512 slides along the same direction as the traveling direction of the bicycle, the height of the conductive moving part 512 relative to the frame 5 gradually increases; that is, the bottom wall of the housing 511 is higher at the end near the front than the bottom wall of the housing 511 at the end near the rear, so that the conductive moving member 512 is maintained at a position near the rear of the housing 511 when the bicycle is in a horizontal road.

A first conductive terminal 513 is provided on a side wall of the housing 511 located at the front end in the traveling direction of the bicycle, and the first conductive terminal 513 is electrically connected to the battery 6.

When the conductive moving part 512 slides towards the first conductive terminal 513 and abuts against the first conductive terminal 513, the conductive moving part 512 further abuts against the second conductive terminal 514. The conductive moving part 512 is influenced by gravity on the bottom wall of the housing 511 to be kept at the lowest point, and when the bicycle is in a deceleration state, the conductive moving part 512 can move towards the first conductive terminal 513 under the action of inertia force so as to abut against the first conductive terminal 513 and the second conductive terminal 514 simultaneously; or when the bicycle is in a downhill section, the relative height of the front wheel of the bicycle is lower than the relative height of the rear wheel 52 of the bicycle, which may cause the relative height of the lowest point of the bottom wall in the housing 511 to be higher than the relative height of the highest point of the bottom wall in the housing 511, so that the conductive moving member 512 slides toward the first conductive terminal 513, thereby triggering the first conductive terminal 513 and the second conductive terminal 514 to be electrically connected. In the present embodiment, the conductive moving part 512 is a metal block. In other embodiments, the conductive moving part 512 may also be a metal ball. And the mounting of housing 511 can be adjusted to facilitate changing the triggering condition of conductive movable member 512 within housing 511.

A display screen 56, a control switch 57 and a flexible solar panel 58 are also provided on the frame 5. The display screen 56 is electrically connected with the battery 6, the control switch 57 is connected with the state trigger switch 51 in parallel, and the flexible solar panel 58 is electrically connected with the battery 6. The display screen 56 is arranged at the position of the frame 5 at the handle bar, and the display screen 56 displays the current remaining power. When the remaining capacity of the battery 6 is insufficient, if the trigger condition of the state trigger switch 51 is not satisfied or indirectly satisfied, the electric cylinder 55 may be additionally controlled to be started through the control switch 57, so as to charge the battery 6 in time. In addition, the flexible solar panel 58 can continuously charge the battery 6 during the day, largely keeping the battery 6 in a full state.

The implementation principle of the embodiment of the application is as follows: the power supply mode of the warning lamp 3 is selected in a self-adaptive mode according to the riding state and the running environment, and when a rider rides on the bicycle, the output electric energy is directly provided for the warning lamp 3 through the first generator 4. When the bicycle is ridden at night, the battery 6 and the light control switch 8 are used for keeping the turn-on state of the warning lamp 3 all the time. When the rider does not apply force to ride, the second generator 54 can be triggered to charge the battery 6, so that the energy utilization rate is improved.

The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
