Detailed ways

Example

As shown in Figures 1 to 4, a stroller frame includes a front pole 10, a rear pole 11, a driver pole 12 and a seat pole 13. The rear pole 11 is movably connected to the front pole along the length direction of the front pole 10. Post 10, the lower side of the seat post 13 is hinged to the rear side of the front stem 10, the lower side of the rider stem 12 is hinged to the rear side of the rear stem 11, the seat stem 13 is hinged to the rider stem 12, so that the rear side of the front stem 10, The rear bar 11, the lower side of the rider bar 12 and the lower side of the seat post 13 form a triangular structure.

It should be noted that the rear pole 11 is plugged into the inside of the front pole 10, and the hinge point of the driver pole 12 and the seat pole 13 is located at the middle position of the driver pole 12 and the seat pole 13, and is not limited to the middle position, as long as it can Just form the above triangular structure. The rear side of the front pole 10, the rear pole 11, the underside of the driver pole 12 and the underside of the seat pole 13 form a triangular structure. The rear side of the front pole 10 and the rear pole 11 together form the bottom of the triangular structure, and The base is retractable. Therefore, when folding, first rotate the seat post 13 to the front side of the frame, the rider post 12 and the seat post 13, the front post 10 and the seat post 13, the rear post 11 and the rider post 12 rotate around their respective hinge points, The rear rod 11 moves toward the inside of the front rod 10, thereby shortening the length of the rear rod 11 extending out of the front rod 10, as shown in Figures 1 and 3. When unfolding, the seat post 13 is rotated in the opposite direction, and the rear post 11 extends from the inside of the front post 10 .

The above technical solution adopts a method in which the front rod 10 and the rear rod 11 can be retracted when folded, so that the volume of the frame of the baby stroller after folding can be smaller, making it more convenient to carry and occupying less space when stored.

It should be additionally explained that the above-mentioned handlebar 12 is used for installing the seat of the baby stroller.

Further, the lower side of the seat post 13 and the rear side of the front post 10 are hingedly connected through the rotating shaft 26.

Further, the lower side of the driver's pole 12 and the rear side of the rear pole 11 are hingedly connected through the rotating shaft 37.

Furthermore, the seat post 13 and the handlebar 12 are hingedly connected via a rotating shaft 5.

Further, two groups of front pole 10 , rear pole 11 and rider pole 12 are provided, and are symmetrically arranged on both sides of the seat pole 13 .

Further, the front end of the front rod 10 is fixedly connected to the front cross frame 2, and front wheels 21 are installed at both ends of the front cross frame 2.

Further, a rear cross frame 3 is fixedly connected to the rear end of the rear rod 11 , and rear wheels 31 are installed at both ends of the rear cross frame 3 .

Furthermore, a handlebar 4 is movably inserted into the seatpost 13 , and the handlebar 4 can telescope along the length direction of the seatpost 13 .

It should be noted that when folding, the handle bar 4 can be retracted to the inside of the seat bar 13 to reduce its extended length, thereby reducing the space occupied by the stroller after folding.

It should be noted that the two front rods 10 are hinged to the two sides of the seat rod 13 through the second shaft 6, and the two rider rods 12 are hinged to the two sides of the seat rod 13 through the first shaft 5. The two rear rods 11 and the two rider rods 12 are hinged through the third shaft 7, or the two rear rods 11 can be fixedly mounted on the rear cross frame 3, and the rear cross frame 3 and the two rider rods 12 are hinged through the third shaft 7.

It should be added that in order to control the rotation angle of the seat post 13 when unfolding and to prevent the rear post 11 from completely moving out of the front post 10, a limiting mechanism can be provided to adjust the rotation angle of the seat post 13. Limit. The limit mechanism can be a mechanism that directly controls the rotation angle of the seat post 13. For example, a limit block is provided between the two front posts 10. When the seat post 13 is rotated to unfold the stroller, the bottom end of the seat post 13 Contact with the limit block prevents the seat post 13 from continuing to rotate and excessively unfolding the stroller. Other methods can also be used, such as limiting the rotation angle between the driver pole 12 and the rear pole 11 .
