DETAILED DESCRIPTION

[0016] The drawings are only for illustrative purposes and cannot be construed as limiting the present invention. To better illustrate the present embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are only for illustrative purposes and cannot be construed as limiting the present invention.

[0017] See also Figures 1 to 3As shown, a brake structure of a baby stroller includes: a brake pedal, a rear wheel seat assembly, and a rear wheel assembly. The rear wheel seat assembly is installed at one end of a connecting rod, the brake pedal is hinged to one side of the rear wheel seat assembly, the rear wheel seat cover is installed inside the rear wheel seat assembly and forms a cavity, the brake slider and the brake pin are arranged in the cavity, the rear wheel assembly is hinged to the rear wheel seat cover through a rotating shaft, one side of the rear wheel seat assembly is provided with a hole, the hole is connected to the cavity, the brake top block is inserted in the slot and supports one end of the brake slider through the inclined surface at the bottom, the other end of the brake slider supports the brake pin, one end of the brake pin supports the slot of the brake slider through a telescopic spring, the other end of the brake pin is sleeved with a return spring, and a circle of brake holes for the brake pin to be inserted is arranged around the rotating shaft of the rear wheel assembly. The brake top block, the brake limit spring, the brake limit pin and then the brake pedal are installed in the rear wheel seat assembly in sequence, and riveted to fix the holes.

[0018] Installation steps: 1. Install the brake slider into the brake pin telescopic spring, then install the brake pin, align the hole position, and then install the brake stop pin. After inserting the brake return spring, install it into the rear wheel seat cover; 2. Assemble the rear wheel seat into the quick-release iron sheet and then the quick-release spring. Install the quick-release iron sheet stop pin into the rear wheel seat cover, align the hole position, pass it through the quick-release iron sheet slot, position it, and then tighten it with screws; 3. Install the brake top block, brake limit spring, brake limit pin and then the brake pedal in the rear wheel seat assembly in turn, align the holes and fix it with rivets; 4. Assemble the rear wheel seat into the rear wheel assembly so that the quick-release iron sheet is stuck in the rear wheel axle slot to complete.

[0019] In the above solution, the brake slider is provided with a slide groove, the pin passes through the slide groove and is inserted into the round hole of the brake pin, and the pin moves along the slide groove. The bottom of the brake top block is an inclined surface, and the top of the brake top block is an arc surface, which corresponds to the bottom slide groove surface of the brake pedal.

[0020] In the above scheme, a quick-release iron sheet is provided at the bottom of the rear wheel seat assembly, and a circular arc groove is provided at the top of the quick-release iron sheet. The circular arc groove corresponds to the concave ring at one end of the rotating shaft of the rear wheel assembly, and the circular arc groove is stuck in the concave ring. The quick-release iron sheet is provided with a mounting hole, and the quick-release spring is installed in the mounting hole. A semicircular hole is provided at the bottom of the mounting hole. The quick-release iron sheet stop pin runs through the mounting hole and is inserted between the rear wheel seat cover and the rear wheel seat assembly, and the bottom of the quick-release spring presses against the quick-release iron sheet stop pin.

[0021] Braking status: When the brake pedal is stepped on, the brake top block is driven downward and the brake slider is driven outward by the inclined surface to compress the brake return spring, so that the brake pin protrudes out of the rear wheel seat cover and is then inserted into the brake hole of the rear wheel assembly to complete the braking. At this time, the brake limit pin slides from the upper hole of the brake pedal to the lower hole to achieve the function of limiting the brake pedal, preventing the brake pedal from failing without external force during braking.

[0022] Coasting state: When the brake pedal is lifted, the brake return spring causes the brake slider to drive the brake pin to retract and reset, and the brake top block will also reset. At this time, the brake limit pin slides from the lower hole of the brake pedal to the upper hole to fix the brake pedal, and the brake is unlocked.
