Description

A kind of bicycle

One, technical field

This utility model belongs to bicycle and man field, particularly relate to a kind of quickly, ride easily that manpower pedal is voluntarily Car.

Two, background technology

The bicycle of manpower pedal, the most perfect through the fast development of nearly 150 years at present, especially in terms of weight more Coming the lightest, a lot of new materials are used for this field, bring a lot of changes of bicycle art, due to vehicle weight saving, Riding speed is accelerated the most accordingly, but bicycle develop into so far, for most of bicyclists, speed is the slowest A kind of vehicles, are difficult to meet the needs of bicyclist, and main cause here is caused by its driving structure, causes its Speed can not get improving.

Three, summary of the invention

This utility model can make the riding speed of current bicycle obtain a certain degree of raising, is that the physical ability of people is entered A kind of bicycle that one step plays.

The technical solution of the utility model is: it includes two wheels, big frame, direction fork and direction hands handle, saddle, with And brake unit, chain wheel, chain, flywheel, it is characterized in that: on each rotary crank 1 of bicycle, set up a long strength of one's legs Bar 2 and a short strength of one's legs bar 3 and a connecting rod 4, the lower extreme point 6 of long strength of one's legs bar 2 and the left junction point 15 on rotary crank 1 Being connected by bearing, the upper extreme point 7 of long strength of one's legs bar 2 installs pedal spindle 8, on the lower extreme point 10 of short strength of one's legs bar 3 and rotary crank 1 Right junction point 16 is connected by rotating shaft, and short strength of one's legs bar 3 upper extreme point 9 is connected by rotating shaft with the right endpoint 12 of connecting rod 4, connecting rod Left end point 11 on 4 point 17 on the upper side with the lower end on long strength of one's legs bar 2 is connected by rotating shaft, short strength of one's legs bar 3 middle have one curved Curved bar 5, bent stick 5 and short strength of one's legs bar 3 are an entirety, bent stick 5 overcoat one spring 13, the other end of spring 13 and rotation song The end point 14 of handle 1 connects.

The beneficial effects of the utility model are: one, owing to the speed of bicycle is improved, and save the body of people Power, so, result in bicycle and has obtained further development, so that human society is the simplest as a kind of vehicles The easy vehicles are more perfect, and its development space will be bigger, more can meet teenager, particularly the needs of middle school student.Its Two, due to the raising of bicycle speed per hour, electric bicycle, by some by voluntarily in solo both vehicles Car replaces, and so, is more convenient for the crowd of certain muscle power.Its three, due to bicycle be one be relatively easy to control The vehicles of the energy-conserving and environment-protective of system, are again a kind of vehicles taken exercises, thus will emerge in large numbers the love of large quantities of bicycle Good person, thus a collection of new sports items also will occur accordingly, make people using it both as the vehicles, again as taking exercise The instrument of health, thus the health for the mankind contributes.

Below in conjunction with the accompanying drawings, this utility model is further described.

Four, accompanying drawing explanation

Accompanying drawing is rotary crank and element structure side elevation schematic diagram thereof.

In figure: 1 is the rotary crank of bicycle；2 is long strength of one's legs bar；3 is short strength of one's legs bar；4 is connecting rod；5 is bent stick； 6 is long strength of one's legs bar lower extreme point；7 is long strength of one's legs bar upper extreme point；8 is pedal spindle；9 is short strength of one's legs bar upper extreme point；10 is short strength of one's legs bar Lower extreme point；11 is connecting rod left end point；12 is connecting rod right endpoint；13 is spring；14 rotary crank end point；15 for rotating song The left junction point of handle；16 is the right junction point of rotary crank；17 is long strength of one's legs bar lower end point on the upper side.

Five, detailed description of the invention

In order to make the leg power of bike rider use just right degree, this utility model is described voluntarily Car: it includes two wheels, big frame, direction fork and direction hands handle, saddle, and brake unit, chain wheel, chain, flywheel, its Feature is: set up a long strength of one's legs bar 2 and a short strength of one's legs bar 3 and a company on each rotary crank 1 of bicycle Extension bar 4, the lower extreme point 6 of long strength of one's legs bar 2 is connected by bearing with the left junction point 15 on rotary crank 1, the upper end of long strength of one's legs bar 2 Point 7 installation pedal spindle 8, the lower extreme point 10 of short strength of one's legs bar 3 is connected by rotating shaft with the right junction point 16 on rotary crank 1, short foot Power bar 3 upper extreme point 9 is connected by rotating shaft with the right endpoint 12 of connecting rod 4, left end point in connecting rod 4 11 with on long strength of one's legs bar 2 Lower end point 17 on the upper side connected by rotating shaft, short strength of one's legs bar 3 middle has the bent stick 5, bent stick 5 with short strength of one's legs bar 3 to be One entirety, bent stick 5 overcoat one spring 13, the other end of spring 13 is connected with the end point 14 of rotary crank 1.(such as figure institute Show).

The manner is to utilize the mechanics principle of lever, and it is the lightest with bicyclist that foot makes the speed of bicycle reach perfect condition Pine.
