Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Embodiment 1
As shown in Figure 1-3, the present invention provides a kind of bicycles of gear shifting structure, including voluntarily vehicle main body 1, voluntarily car owner
Body 1 is made of vehicle frame 2, front-wheel 3, handle 4, cushion 5, rear-wheel 6 and pedal 7, and front-wheel 3 and rear-wheel 6 are movably installed in vehicle frame 2 respectively
Rear and front end, handle 3 is installed on the top of 2 front end of vehicle frame, and cushion 5 is installed on the top of 2 middle-end of vehicle frame, ride 7 by from
Driving axis is movably installed in the bottom of 2 middle-end of vehicle frame, and foot-operated 7 are fixedly installed on bicycle middle shaft with chain wheel 8, rear-wheel
Derailleur 10 and flywheel 11 are installed, chain wheel 8 is sequentially connected by chain 9 and flywheel 11, and chain 9 passes through in 6 installation axle
Derailleur 10；Infrared ray heart rate detector 12, stm32 single-chip microcontroller 13 and electronic gear shifter 14, the infrared ray heart are installed on handle 4
Battery 15 is installed, the side of infrared ray heart rate detector 12 is equipped with power switch, stm32 single-chip microcontroller in rate detector 12
13 connect with 12 signal of infrared ray heart rate detector, and stm32 single-chip microcontroller 13 is electricly connected with electronic gear shifter 14, electronic gear shifter
14 are connected by gear shift rope and the control of derailleur 10.
The surrounding of infrared ray heart rate detector 12 is provided with several infrared light-emitting diodes, with heartthrob, human body
Tissue translucence changes correspondingly.When blood is sent to tissue, the translucence of tissue reduces；When blood flows back to heart,
The translucence of tissue increases.This phenomenon is the most obvious at positions such as the relatively thin finger tip of tissue, ear-lobes.Therefore, red
The infrared radiation that outside line heart rate detector generates infrared light-emitting diode to the above-mentioned position of human body, and be mounted in the position
The infrared photocell on the other side or side detects the transparency of body tissue and converts it to electric signal.Due to this signal
Frequency it is directly proportional to human body pulse rate per minute, as long as therefore convert it to pulse and carry out shaping, counting and display,
It can be achieved with the purpose of real-time detection pulse rate.The side of infrared ray heart rate detector 12 is provided with electrically to be connected with battery 15
The charging jack connect, the top of infrared ray heart rate detector 12 are provided with the power supply indicator being electrically connected with battery 15, side
Just it charges in time for detector.
Concrete operating principle：Ride the bicycle when, first by power switch open infrared ray heart rate detector 12,
During riding, heart rate detector can detect the beat pulse frequency of bicyclist, and will test signal and pass to stm32 monolithic
Machine 13, single-chip microcontroller identify the signal of collection, when bicyclist rides it is more difficult when, beat pulse frequency is higher, monolithic
Machine control electronic gear shifter 14 is shifted gears, and electronic gear shifter 14 controls derailleur 10 by gear shift rope, and chain 9 is changed to flywheel
The flywheel on piece being relatively large in diameter in 11 reduces difficulty of riding；When heart rate detector detects that pulse frequency is gradually recovered normally, electricity
Chain 9 is changed to the lesser flywheel on piece of diameter in flywheel 11 again by sub- selector 14, to increase riding speed.
The beneficial effects obtained by the present invention are as follows being：The device can be automatically adjusted certainly by the changes in heart rate of detection bicyclist
The gear of driving, it is convenient and efficient without manually adjusting；And the apparatus structure is simple, manufacturing cost is low, is suitble to promote the use of.
Finally it should be noted that：The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention,
