Abstract

The utility model relates to a safe and light bicycle. The utility model comprises a tripod, wheels, handlebars, a saddle, foot boards, etc., wherein, force application rods, swinging rods, etc. are connected with cranks in pedal systems designed to be eudipleural; vertical bearing rods, swinging rods, connecting rods, springs, etc. are designed to arrange on a saddle system; the design of the pedal systems and the design of the saddle system enable the utility model to lengthen distance from the shaft center of a disk chuck to pedal plates, the utility model on which people ride can be laboursaving, and the movement radii of feet can be correspondingly smaller; when a bicycle is pedaled under large force, the centre of gravity of a saddle cushion is higher; when the bicycle is pedaled under smaller force, the saddle cushion is downwards and backwards shifted under the action of the pressure of a human body, and thus, the utility model is comfortable and laborsaving to ride.

Description

Safe portable bicycle

The utility model relates to the manpower transportation field, and particularly a kind of footstep mechanism and seat mechanism are the safe portable bicycle of labor-saving structure.

At present, the bicycle kind of all kinds structure is a lot, and ordinary bicycle, variable speed bicycle, anti-vibration bicycle etc. are arranged, and these bicycles all have advantage separately, ride lightly inadequately, safe, comfortable but have, vehicle seat can not move forward and backward etc. not enough with the big or small center of gravity of exerting all one's effort.

The purpose of this utility model is the deficiency at above technology, designs a kind of foot-operated part and seat mechanism and is labor-saving structure, the light bicycle of safety when riding.

The purpose of this utility model can be achieved through the following technical solutions: design the light bicycle of a kind of safety, comprise spider, wheel, handlebar, vehicle seat, foot-operated etc., link by bearing pin and force application rod at a end with the joining machine thigh of bicycle floral disc, one termination stretcher of force application rod, the other end joins by bearing pin and rocking bar, the other end of rocking bar by bearing pin be fixed on the fixed card that car sticks and join.Bicycle saddle and preceding perpendicular pole, the perpendicular pole in back are joined, and the perpendicular pole in back is joined by bearing pin and preceding rocking bar, back link rod respectively.Before perpendicular pole join by an end and the preceding link rod of bearing pin and preceding rocking bar respectively, the other end of preceding link rod joins by the vehicle seat head of bearing pin and bicycle tripod, the other end of back link rod is respectively by bearing pin and assign the seat rod in the vehicle seat head to join; The two ends of the bearing pin of link rod and back link rod are respectively equipped with the spring that back link rod and preceding link rod are made progress before connection.

The utility model compared with prior art partly adopts labor-saving structure at foot-operated partial sum vehicle seat, and safety labor-saving is comfortable when riding.Has certain health function.

Below in conjunction with accompanying drawing the utility model is described in further detail: design a kind of safe portable bicycle, comprise spider 4, wheel 1,7, handlebar 5, vehicle seat 3, stretcher 10,10 ' etc., the pedal 39 systems left-right symmetric design of bicycle, with bicycle floral disc 15 joining machine thighs 9,9 ' the other end is by bearing pin 19,19 ' with force application rod 11,11 ' links, force application rod 11, a termination stretcher 10 of 11 ', 10 ', the other end is by bearing pin 18,18 ' with rocking bar 17, an end of 17 ' joins, and the other end of rocking bar is by bearing pin 20,20 ' with the fixed card 16 that is fixed on the car fork 13,16 ' links.Because machine thigh 9,9 ', force application rod 11,11 ', rocking bar 17,17 ' interrelation, the floral disc axle center of having extended was to stretcher 10,10 ' distance when bicycle was ridden, thereby made that the amount of riding is laborsaving, and the moving radius of pin is less relatively.The vehicle seat pad 3 and the preceding perpendicular pole 30,31 of bicycle saddle 40, the perpendicular pole 24,28 in back is joined; The perpendicular pole 24,28 in back is respectively by bearing pin and preceding rocking bar 25,33, and back link rod 23,20 joins.Before perpendicular pole 30,31 join by an end and the preceding link rod 26,29 of bearing pin and preceding rocking bar 25,33 respectively: the other end of preceding link rod 26,29 joins by the vehicle seat head 37 of bearing pin 36 with bicycle tripod 4, the other end of back link rod 20,23 respectively by bearing pin 34 and assign in seat 37 in seat rod 32 join.Be respectively equipped with the spring 22,35,27,38 that back link rod 20,23 and preceding link rod 26,29 are made progress at the two ends of bearing pin 34,36.This bicycle saddle 40 seat cushion center of gravity when pressing down with the foot to pedal is higher; When not too with strength center of gravity low and after move, thereby comfortable laborsaving when riding.6 is before the car watt among the figure, and 7 be that front-wheel, 8 is front fork, 5 be handlebar, 21 for brake, 1 for trailing wheel, 2 for shelf, 14 for after watt, 12 be chain cover.
