Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the specific embodiments.

Referring to fig. 1, the foldable stroller includes a frame having an unfolded state and a folded state, and a wheel assembly disposed at the bottom of the frame, wherein the frame includes two side brackets 10 respectively disposed at the left and right sides, a cross brace assembly 40 disposed between the two side brackets 10 and foldable along the left and right direction, and a flexible foot pedal 1 disposed between the two side brackets 10 and extending along the left and right direction. The flexible pedal part 1 is rotatably arranged between the side brackets 10 on the two sides, when the frame is in a folding state, the side brackets 10 on the two sides are folded along the left-right direction, the flexible pedal part 1 is folded between the two groups of side brackets 10 along the length direction, and in the folding process, the flexible pedal part 1 rotates relative to the side brackets 10, so that the opposite side brackets 10 are drawn close, and the folding of the flexible pedal part 1 along the length direction is smoother.

Referring to fig. 2 to 10, both ends of the flexible foot pedal 1 are rotatably connected to the corresponding side brackets 10 about the rotating shafts 4, respectively, and the axial lines of the rotating shafts 4 extend in the front-rear direction. Referring to fig. 2 and 3, the axial lines X of the rotating shafts 4 on both sides extend obliquely from outside to inside in the left-right direction from front to back. In the folding process of the flexible pedal part 1, the two side rotating shafts 4 are arranged to enable the flexible pedal part 1 to arch forwards from outside to inside when being folded, so that the folding width of the whole trolley is reduced when the trolley is folded.

Specifically, each side bracket 10 has at least a mounting rod extending in the up-down direction, on which a mounting seat 5 is fixedly provided, and the flexible foot rest 1 is rotatably connected to the mounting seat 5 about the rotation shaft 4. Here, the side brackets 10 of each side include a front bar 2 extending obliquely upward from front to rear and a rear bar 3 extending obliquely upward from rear to front, and the wheel assembly includes a front wheel assembly 20 provided at the bottom of the front bar 2 and a rear wheel assembly 30 provided at the bottom of the rear bar 3. The front support rods 2 constitute the above-mentioned mounting rods, and the flexible foot pedal 1 is mounted between the lower portions of the front support rods 2 on both sides.

Referring to fig. 2 to 5, the front support bar 2 includes a bar body 21 extending in an up-and-down direction, and a connecting head 22 fixed to a lower portion of the bar body 21, and the front wheel assembly 20 is mounted at a bottom of the connecting head 22. The mounting seat 5 is fixed on the connecting head 22 by the bolt 6, the connecting head 22 has the arc-shaped bent portions 22a bent inward and downward in the left-right direction, the flexible foothold 1 is positioned between the arc-shaped bent portions 22a at both sides, and the front side edge of the flexible foothold 1 is flush with the front side edge of the connecting head 22. This makes the connection of the flexible footrest member 1 between the front stays 2 on both sides very smooth, resulting in a great improvement in the aesthetic appearance of the front portion of the frame.

Referring to fig. 4 to 8, the flexible footrest member 1 includes a footrest body 11 extending in the left-right direction, and two extension tips 12 extending outward from both ends of the footrest body 11, the extension tips 12 being provided on opposite sides of the rotation shaft 4 from the footrest body 11 on each of the left and right sides of the frame, the extension tips 12 extending obliquely outward and upward from the footrest body 11. The front support rod 2 is provided with a containing groove, and the extending end 12 is inserted into the containing groove in a matching way.

Thus, in the process that the side brackets 10 on the two sides are folded in the left-right direction when the frame is folded, the extending ends 12 at the two end parts of the flexible pedal member 1 are pressed downwards on the upper side groove wall of the accommodating groove on the front supporting rod 2, the two ends of the pedal body 11 in the middle of the flexible pedal member 1 can be pulled, and then have the trend of moving upwards, so that the middle part of the pedal body 11 is arched upwards. The flexible pedal 1 is divided into a first part 1A and a second part 1B which have the same length along the length direction of the flexible pedal, the first part 1A and the second part 1B extend along the up-down direction and are mutually folded along the left-right direction, and the folding process is smoother.

In this embodiment, referring to fig. 5, the pedal body 11 of the flexible pedal member 1 has a pedal support portion 11A extending in the front-rear direction and a front edge portion 11B extending downward from the front side of the pedal support portion 11A, the front edge portion 11B has an inverted V-shaped opening 11c in the middle, and the frame is folded in a folded state, and the pedal body 11 is folded about the opening 11c, so that the first portion 1A and the second portion 1B are respectively disposed on the left and right sides of the opening 11c, further facilitating the folding of the flexible pedal member 1.

In summary, in the folding cart of the present embodiment, two ends of the flexible pedal 1 are respectively and rotatably connected to the side brackets 10 at two sides, and the connection between the flexible pedal and the side brackets 10 at two sides is smoother, so that the overall aesthetic degree of the frame is improved; meanwhile, the two ends of the flexible pedal part 1 can respectively rotate around the rotating shaft 4 relative to the side brackets 10 in the folding process of the frame, so that the flexible pedal part 1 can be folded more smoothly along the length direction of the flexible pedal part 1.

The above-mentioned embodiments are merely illustrative of the technical idea and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the scope of the present invention.
