Abstract
The utility model relates to a safe power-saving bicycle, which is composed of a bicycle frame, wheels, a flywheel, pedals, etc. The bicycle is provided with a four-rod force applying mechanism which is composed of a bicycle frame 1, a driven crank 11, a force applying rod 9 and a swinging rod; the mechanism is arranged at both sides of the bicycle symmetrically. Owing to the arrangement of the four-rod force applying mechanism, the height and the dimension of the whole bicycle body is reduced, thus the riding barycenter is lowered, and the utility model has compact structure and stability increased. Simultaneously owing to the implementation of the mechanism, the force arm of the utility model is increased, and the utility model is labor-saving and safe to ride.
Description
The utility model belongs to the traffic and transport field that daily life is used, and specifically, is a kind of safety labor-saving bicycle.
At present, the bicycle of various classifications and structure is a lot of, as: ordinary bicycle, variable speed bicycle, shock-absorbing car, boosted vehicle etc., above bicycle is all required great effort when riding because the distance of pedal and axis is limit.
The purpose of this utility model is a kind of safe, flexible, comfortable, stable, labour-saving safety labor-saving bicycle of design.
The utility model as shown in Figure 1, remove by vehicle frame 1, outside wheel 7, flywheel 6 and pedal 10 etc. are formed, also form one or four bar force application mechanisms by vehicle frame 1, driven crank 11, force application rod 9 and fork 14, this mechanism's symmetry is located at the bicycle both sides: an end of driven crank 11 is fixed on the axis 5, and the other end and force application rod join by bearing pin 20, and an end of force application rod is provided with pedal 10, the other end joins by bearing pin 18 and fork 14, and the fork other end is fixed on the vehicle frame by bearing pin 19.
The utility model compared with prior art because vehicle frame 1, driven crank 11, force application rod 9, fork 14 formed four bar force application mechanisms, whole bodywork height size descends, compact conformation, stability increases, and the human buttock keeps the best to contact with saddle when riding, and is comfortable laborsaving.Fig. 1 is a structural representation of the present utility model, and wherein 2 is handlebar, and 3 is front fork, and 4 is that axletree, 8 is that mud plate, 12 is that chain, 13 is that chain guard, 15 is that clothes hanger, 16 is saddle, and 17 is brake.
Enforcement of the present utility model as shown in Figure 1, form setting up of one or four bar force application mechanisms, this mechanism by vehicle frame 1, driven crank 11, force application rod 9, fork 14, make the path of motion of pedal be approximately oval, long axis length has about about 20 a ° angle greater than diameter, major axis and the ground of ordinary bicycle pedal circular path, makes path of motion be suitable for the human body application of force.Pedal path of motion limes superiors position is a little more than axis 5, and smallest limit position and ground maintain a certain distance, and makes that pedal 10 is unlikely to contact with ground.Use four bar force application mechanisms, the position of exerting all one's strength on average moves down.Adopt four-bar mechanism, firmly rationally, stability increases, and it is laborsaving, light to ride.
Claims (1)
- A kind of by vehicle frame 1, the bicycle that wheel 7 and transmission device are formed, it is characterized in that forming one or four bar force application mechanisms by vehicle frame 1, driven crank 11, force application rod 9 and fork 14, this mechanism's symmetry is located at the bicycle both sides, one end of driven crank 11 is fixed on the axis 5, and the other end and force application rod 9 join by bearing pin 20, and an end of force application rod is provided with pedal 10, the other end joins by bearing pin 18 and fork 14, and the other end of fork is fixed on the vehicle frame by bearing pin 19.
