Abstract

The utility model relates to a children's bicycle which integrates recreation, body-building, and ride into an integral body. Except that a front wheel of the children's bicycle which integrates recreation, body-building, and ride into an integral body is provided with a circle center shaft hole, and the front wheel is also provided with an eccentric shaft hole. A front shaft hub can be matched with any one hole. When the front shaft hub is arranged on the circle center shaft hole, the children's bicycle which integrates recreation, body-building, and ride into an integral body is a common children's bicycle. When the front shaft hub is arranged on the eccentric shaft hole, a bicycle front fork and a bicycle handle follow the rotation of an eccentric front wheel to undulate from top to bottom, and the children's bicycle which integrates recreation, body-building, and ride into an integral body has running effect like riding on a horse. A flywheel is also arranged on the front shaft hub of the children's bicycle which integrates recreation, body-building, and ride into an integral body. A crank is fixedly arranged on an outer ring of the flywheel, and the crank, a connecting rod, a rocking rod, etc. form a plane four-connecting rod mechanism. The rocking rod can be pushed and pulled to generate driving force to a front wheel; meanwhile, and horse running undulating effect is increased.

Description

Body-building amusement horse formula perambulator

The utility model relates to a kind of child's bicycle, a kind ofly specifically collects amusement, body-building, riding instead of walk is the bicycle of one.

People are in order to temper child's brave spirit in amusement, simultaneously again can body-building and invented multiple perambulator with functions such as amusement, body-building, and wherein with the perambulator of the action design of imitation horse typical case comparatively.This class perambulator structurally mainly is to make vehicle frame heave and set in wheel by eccentric wheel or elliptic wheel, also has by piston crank mechanism to drive the up and down perambulator of vehicle seat.The deficiency of above-mentioned perambulator is that function is fixed, can not the common perambulator usefulness of double as, and type of drive is single, and is recreational not strong, and because the car trailing wheel that has is eccentric or oval, so the balance wheel on former the sending a car is forced to cancellation, therefore poor stability when riding.

The purpose of this utility model is to provide a kind of activity posture undulatory motion that both can imitate horse, can ride by the common perambulator of double as again; Both can move with hand again with the heave and set of advancing of car, and by driving the body-building recreation perambulator that car is advanced with hand moving.

The purpose of this utility model is achieved in that increases an eccentric pivot hole again on the basis of the original center of circle of car front-wheel axis hole, and have can with any one front axle skin that cooperates in these two axis holes, on the front axle skin flywheel is housed, the fixing crank that is equipped with on the outer ring of flywheel, and the lanar four rod mechanism that is made of jointly flywheel and crank, connecting rod, rocking bar, handlebar, front fork is arranged.

Fig. 1 is a horse formula perambulator transverse integral scheme drawing.

Fig. 2 is that the A of Fig. 1 is to scheme drawing.

Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is elaborated.

Among Fig. 1,1 is rocking bar, and 2 is connecting pin, and 3 is connecting rod, and 4 is the front axle skin, and 5 is flywheel, and 6 is crank, and 7 is front-wheel, and 8 is center of circle axis hole, and 9 is handlebar.Skin 4 is eccentric the installation before in the present embodiment, and promptly front axle skin 4 is contained in the eccentric pivot hole 10.Crank 6 on flywheel 5 outer rings, connecting rod 3, rocking bar 1, handlebar 9 connect successively by connecting pin 2 respectively, and constitute lanar four rod mechanism thus.

Among Fig. 2, the lanar four rod mechanism shown in Fig. 1 is two groups, these two groups of lanar four rod mechanism symmetries be contained in front-wheel 7 both sides.

From Fig. 1 and Fig. 2 as seen, when front-wheel 7 rotated, because eccentric action, front fork 11 and handlebar 9 can heave and set, and the rider just has the sensation of riding and running.If, not only can increase power, and can increase the effect of galloping horse to car with the hand bar 1 that shakes.The rider can own control link when the push-and-pull rocking bar stroke, promptly can control the rotational angle that crank drives flywheel, perhaps 360 degree, perhaps in less than the scopes of 180 degree back and forth.

Two groups of lanar four rod mechanisms in the present embodiment are two groups of mechanisms independently, and therefore, two groups of rocking bars of push-and-pull both can carry out simultaneously, also can one push away one and draw and hocket.If only need two groups of rocking bars to carry out simultaneously, two groups of four-bar linkages can also be coupled together by pipe link, two groups of four-bar linkages can only be moved simultaneously.As: in two groups of lanar four rod mechanisms, the connecting pin of connecting rod and rocking bar junction is coupled together by pipe link, two groups of lanar four rod mechanisms just can only move together.

Structure of the present utility model is comparatively simple, and except that front-wheel had bigger variation, other parts all got final product with the component assembly of standardized parts or simple processing.Because the utility model is not changed on trailing wheel, so trailing wheel often has a pair of balance wheel still can keep use on the perambulator, though make this car thrilling, very safe when child rides.

Claims

1, a kind of body-building amusement horse formula perambulator, form by vehicle frame, wheel, vehicle seat, handlebar, pedal, chain gearing etc., it is characterized in that: the front-wheel of this car is except that having a center of circle axis hole (8), the front axle skin (4) that also has an eccentric pivot hole (10) and can cooperate with center of circle axis hole (8) or eccentric pivot hole (10), flywheel (5) is housed on the front axle skin (4), the fixing crank (6) that is equipped with on the outer ring of flywheel (5), flywheel (5) and crank (6) constitute lanar four rod mechanism jointly with connecting rod (3), rocking bar (1), handlebar (9) and front fork.

2, according to the described horse formula of claim 1 perambulator, it is characterized in that: described lanar four rod mechanism or one group, or two groups; Be installed in any side of front-wheel (7) in the time of one group, symmetry is installed in front-wheel (7) both sides in the time of two groups.
