Problems solved by technology
When the cart frame is folded, most of the rods on the cart frame can be close together, but because the front wheel assembly usually stretches forward in front of the frame, the front wheel assembly and the rear wheel assembly are often not close together. Together, the volume of the stroller frame is not compact enough after folding

Embodiment Construction
[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0024] see Figure 1 to Figure 6 As shown, a kind of stroller for children comprises a foldable vehicle frame, and the vehicle frame at least includes a front support 1 and a rear support 2. The rear wheel assembly 4 at the bottom of the bracket 2. When the vehicle frame is unfolded, the front bracket 1 and the rear bracket 2 are relatively expanded, and the front wheel assembly 3 and the rear wheel assembly 4 are jointly supported on the ground;
[0025] Referring to the accompanying drawings, in this embodiment, the vehicle frame also includes a connecting frame 10 and a push rod 12. The connecting frame 10 extends along the front and rear directions. The front end of the connecting frame 10 is pivotally connected to the front bracket 1. The connecting frame 10 The rear end pivot is connected on the rear bracket 2...

The invention discloses a stroller for children, in which a cam slider which can move up and down along the wheel shaft of the front wheel assembly is arranged, and the top end surface of the cam slider along the radial direction of the wheel shaft is in the form of an annular shape with one end lower and the other end high The cam surface, and then set a limit piece on the wheel shaft to limit the upward movement of the cam slider, and set a pulling piece and an elastic piece to control the up and down motion state of the cam slider. When the frame is unfolded, the pulling piece and the elastic piece are released, the annular cam surface is located under the limiter and separated from the limiter, and the front wheel assembly can rotate universally; when the frame is folded, the pulling member is gradually tensioned to make the cam slider go up so that the ring cam The surface resists on the limit piece, and the limit piece slides from high to low along the annular cam surface, and then drives the front wheel assembly to rotate around its axle, so that the front wheel assembly turns backward and moves closer to the rear wheel assembly, which makes the frame The folded structure is more compact, which effectively reduces the folded volume of the vehicle frame.
Description
technical field [0001] The invention relates to a stroller for children, in particular to a stroller for children whose front wheels can automatically turn when folded. Background technique [0002] In the prior art, children's strollers usually include a stroller frame with an unfolded state and a folded state, a front wheel assembly located at the bottom front of the stroller frame, and a rear wheel assembly located at the bottom rear of the stroller frame. A rear wheel assembly, a locking mechanism for locking the stroller frame in an unfolded state. When the cart frame is folded, most of the rods on the cart frame can be close together, but because the front wheel assembly usually stretches forward in front of the frame, the front wheel assembly and the rear wheel assembly are often not close together. Together, the volume of the stroller frame after being folded is not compact enough. Contents of the invention [0003] The object of the present invention is to overc...
