Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing:
Embodiment 1
As shown in Figure 1, showed structure of the present utility model, it comprises vehicle frame, pedal, is fixed on the rear axle 13 on the vehicle frame of back, a radial bearing is respectively installed at the described two ends that are fixed on rear axle on the vehicle frame, and the force 12 of back vehicle frame is connected in the back strong point 11 of vehicle seat by strong point connecting rod 18, fulcrum 20 intersects at vehicle frame 1: 30 by fulcrum connecting rod 19, wherein, described pedal is arranged on and makes on the rear axle 13 of vehicle frame that the people's be subjected to force direction reasonable, when people have been pedaled bicycle, consequently become the state of running, be subjected to force direction good.
The wheel shaft self of described back vehicle frame can rotate, it at first is in the outside of retaining a radial bearing to be housed respectively with installing the trailing wheel of trailing wheel with axle, described radial bearing is stabilized on the vehicle frame by the bearing seat on the vehicle frame, at this moment, on the cooresponding position of rear flywheel, select for use suitable sprocket wheel and pedal connecting rod to be fixed on the rear axle.
The position of vehicle seat is related to the center of gravity of object, according to decomposition of force, the weight that bicycle is being ridden has direct relation with it, distance between the rear fulcrum of vehicle seat and the vertical center line of trailing wheel is 0～200 millimeter, and between strong point connecting rod 18 behind the vehicle seat and vehicle seat perpendicular line certain included angle is arranged, form when people are ridden forwards to power, and this power is directly proportional with described angle, for riding safety, vehicle seat and vehicle frame be fore-and-aft adjustment at any time.Rear axle on the described vehicle frame is connected in lever 26 between force 12 and the fulcrum 20 by vehicle frame and baffle plate.And the rumpbone position 31 of described vehicle seat is a recess, and the edge, back is a convex shape.Wherein, the strong point 10 of described vehicle seat front end is inserted on the vertical tube 24 of vehicle frame and perpendicular line intersection point, wherein, with rear axle 13 is centre point, rear axle 13 is that radius picture arc intersects at a bit on the trailing wheel perpendicular line to the fork length between the axis 16, this intersection point is a point of connection of vehicle frame and vertical tube, and the top of vertical tube and vehicle frame 23 joinings is provided with the preceding strong point 10 that an attachment point is vehicle seat, vehicle frame also comprises a fulcrum connecting rod 19 behind the described bicycle, and an end of this fulcrum connecting rod 19 is connected in fulcrum 20, and the vehicle frame of the other end and bicycle intersects at a point 30.Be connected and fixed with tumbler in the middle of the described bicycle handle bar 28, and a snap close is set, when people use bicycle, get final product, open snap close when not using, bicycle handle bar is folded up with the snap close fastening.
Before described stressed baffle plate 14 and the elastomeric element 15 of back between the stressed baffle plate 22 play forward thrust and to the damping force of human body, because human weight, vehicle seat constantly moves up and down, because the principle of lever makes bicycle obtain a kind of power forward, the cyclist has been played certain power-assisted effect by fulcrum.
