(5) Specific implementation methods:

First of all, the structure of a baby carriage of the present invention, as shown in Figures 1 to 4, includes a main body 10, a support frame 20, a rod set 30 and two steering assemblies 40, the main body 10 is a shell, and the rear has The seat plate 11 has a perforation 12 at the middle end, two extension rods 13 extending outwards in the front, and a plurality of ribs (not shown in the figure) at the bottom of the main body 10 for connecting the support frame 20, the rod group 30 and the two steering components 40;

The support frame 20 contains a rear support 21 supporting the two rear wheels 14, two central struts 22 and a front support 23 of the two front wheels 15. The rear support 21 of the support frame 20 is pivotally connected with a brake lever 24, and the brake lever 24 Pull up (as shown in Figure 1) through a hand lever 25, the two ends of the brake lever 24 can be rubbed to brake the rear wheel 14;

The upper part of the rod group 30 is a handle 31, and the lower part is a pedal rod 32. The rod group 30 is pivotally connected between the two central poles 22. There are two horizontal protruding rods 301 pivotally connected in the main body 10, and the deflection handle 31 and pedal rod 32 are made around the horizontal protruding rods 301. The rod group 30 is located below the two horizontal protruding rods 301 and has two limit rods 302. There are two limiting spaces 221 below the central pole 22 (refer to FIG. 4 ). The limiting rod 302 is inserted into the limiting space 221 to make the handle 31 and the step bar 32 deflect at a predetermined angle, and the rod group 30 Combining a chain 33 and a spring 34, the bar group 30 can pull the chain 33, drive a gear 35 and rotate a transmission shaft 36, there is a one-way bearing in the gear 35 to drive the transmission shaft 36 to rotate the two rear wheels 14, the spring 34 It is connected between the chain 33 and the rod group 30 for restoring the chain 33 and the rod group 30 to their original shape. A steering rod 41 is pivotally connected under the handle 31. The steering rod 41 swings a displacement rod 43 with a short rod 42 . The displacement rod 43 then moves the two steering assemblies 40 to make the two front wheels 15 deflect;

The steering assembly 40 is a U-shaped plate 44, and a pull plate 441 is extended from the U-shaped plate 44. A front wheel shaft 442 is arranged on the outside of the U-shaped plate 44 to connect to the front wheel 15, and a front rod 443 is connected to the inside of the U-shaped plate 44. The front bar 443 is pivotally connected to the front bracket 23 of the support frame 20, so that the two front wheels 15 can be used for deflection, wherein the front wheels 15 and the rear wheels 14 have anti-slip belts 151 and 141 on the surfaces;

With the combination of the above structures, the utility model is a baby carriage structure. During operation, the child sits on the seat plate 11 of the main body 10, steps on the pedal bar 32, holds the handle 31 with the hand, and pushes the hand inward. The handle 31 moves inwards, exerts force outwards relative to the feet, and the pedal bar 32 moves outwards, so that the rod group 30 can pull the chain 33, drive a gear 35 and rotate a transmission shaft 36, and there is a one-way bearing in the gear 35 to drive The power transmission shaft 36 rotates the two rear wheels 14, and then releases the applied force to the handle 31 and the pedal bar 32. The elastic force of the spring 34 supplies the chain 33 and the rod group 30 to restore the original state, and repeats the above-mentioned actions, and then the two rear wheels 14 continuously Rotate to drive the main body 10 and the children on it to move forward;

Children can control the deflection of the front wheels 15 by turning the handle 31. The handle 31 turns to affect the steering rod 41 below. The steering rod 41 deflects a displacement rod 43 with a short rod 42, and the displacement rod 43 pulls the two steering components. 40 turn to an angle, so that the two front wheels 15 are deflected, and the main body 10 and the child riding on it make a turn;

And can pull up the handle bar 25, to link the two ends of the brake lever 24, rub the rear wheel 14 with the two ends of the brake lever 24, and brake the rear wheel 14, stop advancing as a brake;

When the utility model is operated, both hands and feet can be used to control the steering, and can be used as a brake to stop the forward movement. It is safe and can arouse children's interest. It has very good entertainment value and the effect of fitness exercises.
