Technical Field
[0001] This utility model relates to the field of children's stroller technology, and in particular to a children's stroller braking mechanism. Background Technology
[0002] Strollers are common baby and maternity products used to accompany children as they grow. They make it convenient for adults to push the stroller while moving around outdoors, and the children sit comfortably and safely inside. Strollers also come with sunshades and other features. The overall frame and support rods of the stroller are telescopic and adjustable, allowing the stroller to be folded and operated for portability.
[0003] Currently, most strollers require manual control of the handlebars to pull the stroller backward to stop it from moving forward. This requires holding onto the handlebars to control the stroller. Therefore, a braking mechanism that allows users to control the stroller by stepping on the handlebars is needed to free up their hands. Utility Model Content
[0004] The purpose of this utility model is to provide a braking mechanism for a child stroller.

The rear footrest has a rear wheel frame and a rear wheel. The rear wheel frame is located at the end of the rear footrest, with axles at both ends for mounting the rear wheel and a rotating opening in the middle. The pedal is rotatably mounted in the rotating opening. The slider is slidably mounted in the rear wheel frame and cooperates with the pedal. The mounting plate is located at the end of the rear wheel frame and has a movable hole. The rear wheel has multiple brake holes around it. The brake element is movably mounted in the movable hole via a first spring. One end of the pull cord is connected to the brake element, and the other end is connected to the slider. A second spring is sleeved around the pull cord to push the slider away. By stepping on the pedal, the stroller rotates downward, and the pedal pushes the slider to compress the second spring, which in turn moves the pull cord. The pull cord pushes the brake element out of the movable hole, and simultaneously, under the thrust of the first spring, it is inserted into the brake hole for braking. To release the brake, simply reset the pedal. The release of the pedal provides thrust to the slider, the second spring pushes the slider back to its original position, and pulls the pull cord. The pull cord pulls the brake element into the movable hole and compresses the first spring.
[0007] Furthermore, the rear wheel frame has rotating holes on both sides of the rotating opening, and the pedals have rotating rods installed at both ends of the rotating holes.
[0008] Furthermore, the rear wheel frame is provided with a sliding groove, and the slider is slidably installed in the sliding groove. The slider and the pedal are provided with a matching inclined guide. When the pedal is stepped on, the slider is pushed away from it by the inclined guide. When the pedal is reset, the slider moves closer to the pedal.
[0009] Furthermore, the ends of the pull rope are respectively engaged with the slider and the brake component through a locking head, and both the slider and the brake component are provided with locking grooves that cooperate with the locking head.
[0010] Furthermore, the rear wheel is mounted on a seat, which is located inside the mounting plate and has a rope groove. The pull rope is located in the rope groove, and one end of the first spring abuts against the seat and the other end is installed with the brake component.
[0011] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:
[0012] This invention uses a pedal to control the movement of a slider, which in turn controls the movement of a brake component via a pull rope. The brake component engages with the brake hole of the rear wheel to restrict its movement and apply the brake, or disengages from the brake hole to release the brake. This invention provides a braking mechanism that allows users to control the stroller's brakes by foot, freeing up their hands. The ingenious design eliminates the need for complex structures, making it convenient for users. Attached Figure Description
