A kind of body-building vehicle is arranged in the prior art, comprises and front-wheel and vehicle seat bonded assembly front vehicle frame, with vehicle frame behind handlebar, rear axle and the trailing wheel bonded assembly, front vehicle frame and the back central frame beam hinged and the two between retracing spring is housed.This car is defeated by body weight for humans and is compeled vehicle seat forward and backward vehicle frame is opened, and under action of the spring the two is resetted and makes the car reach.Its deficiency is that this car does not have the special driving device, and can not can not cause children's enough interest as the same cruising of perambulator.

The utility model purpose provide a kind of have actuating device again can be as the wave motion formula Health care carriage for children of the same cruising of perambulator.

The utility model comprises vehicle frame, the car fork, front-wheel, stretcher, trailing wheel and vehicle seat, the closed end that it is characterized in that the V-type vehicle frame is installed the car fork, the front truck pedestal is contained in the open end of car fork, front-wheel and stretcher are installed on the front axle, bent axle after the open end frame of V-type vehicle frame is adorned one, back crankshaft two end is respectively installed a trailing wheel, end of crossbeam and V-type vehicle frame that vehicle seat is installed on it are hinged near closed end, the other end of crossbeam and one end movable set are hinged at the other end of the strut bar at bent axle middle part, back, each hinged trace of the open end that its closed end U type on the V-type vehicle frame that is hinged on is cranked arm, the other end of trace is hinged with the other end of the crank that is packed in the back crankshaft two end.

The utility model embodiment accompanying drawings is as follows, wherein:

Fig. 1, Fig. 2 are wave motion formula Health care carriage for children scheme drawing.

Fig. 3 is the Health care carriage for children constructional drawing.

Cock moulding perambulator as shown in Figure 1, Fig. 2 is a fawn moulding perambulator, its concrete structure as shown in Figure 3, the closed end of V-type vehicle frame 1 is installed front fork 2,3 open ends of front axle at the car fork, front-wheel 4 and stretcher 5 are installed on the front axle, back bent axle 6 is equipped with in the vehicle frame rear end, a trailing wheel 7 is respectively adorned at its two ends, the front end and the vehicle frame of crossbeam 9 that vehicle seat 8 is housed is hinged, the rear end of crossbeam and strut bar 10 are hinged, and strut bar other end movable set is at bent axle middle part, back, and crank arm 11 closed end of U type is hinged on the vehicle frame, each hinged trace 12 of its open end, the other end of trace is hinged with the other end of the crank 13 that is packed in the back crankshaft two end, and one of the wheel of crankshaft two end is fixed installation, and one is movable the installation.On front axle 3, adorn one and hold-down arm bonded assembly animal head type 15(such as fawn head dummy or cock head dummy etc.) by 14 of hold-down arms, between hold-down arm top and the car fork extension spring 16 is installed, the hold-down arm middle part is hinged with catch bar 17, it is hinged that the other end of catch bar and one end are hinged on the other end of the arc bar 18 that car sticks, and a bearing pin 19 that is used to promote the arc bar is installed on front-wheel.When children drive, because gravity makes strut bar 10 drop to nadir, this moment, crank 13 was positioned at the bent axle top, the rider presses crank arm 11(or trace 12 downwards with hand) lift on the health, the trace throw crank rotates under leverage, be that rear axle drive trailing wheel advances, when strut bar rose to vertex, health pressed down naturally and makes strut bar get back to the rotation that nadir is finished a week.This moment, human body was up and down floating and moving ahead of wave.Bearing pin 19 in the process of moving ahead on the front-wheel is periodically with arc bar 18 jack-up upwards, through making animal head type 15 periodically swings with arc bar pivotally attached catch bar 17, the floating up and down of the swing of animal head type and human body among running, can make children produce enough interest as animal.

Advantage of the present utility model: 1, this car is provided with drive unit, and cranks arm by pressing The upper limbs of human body is taken exercise fully, owing to adopt leverage, use 1/4th human bady gravitationals health can be lifted, make children not feel tired, easy easy and simple to handle; 2, the animal head type periodic wobble on this car in addition the up and down floating action of human body as animal among running, can improve the interest that children play; 3, this bassinet structure is simple, makes easily, and cost is low, is suitable for the common children's of wage-earners needs.
