Brake mechanism of baby carriage and baby carriage

Abstract

The invention discloses a brake mechanism of a baby carriage and the baby carriage, and relates to the technical field of children products. The brake mechanism comprises at least one brake component and a transmission clutch, and the brake component is installed on a roller bearing frame in a sliding mode with the radial direction of a moving wheel as the sliding direction; the transmission clutch is arranged on a rotating shaft of the moving wheel; the brake mechanism further comprises a rotating piece, a sleeve body mounting seat and a driving assembly, the sleeve body mounting seat is rotationally connected with the roller bearing frame through a torsional spring in a damping mode, and the sleeve body mounting seat is connected with the transmission clutch. The rotating piece is fixed to the sleeve body installation base, the outer wall of the rotating piece is connected with the brake component through a second push-pull connecting piece, the driving assembly is arranged on the rotating piece and connected with the transmission clutch, and the driving assembly is used for driving the transmission clutch to execute opening and closing actions. The brake mechanism is simple in structure, and friction pressure for braking is applied through rotation of the moving wheels; The buffering braking can be achieved, braking sensitivity is improved, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of children's products, in particular to a brake mechanism of a baby carriage and the baby carriage. Background technique [0002] Baby carriages are a kind of children's toys, including children's bicycles, children's strollers, baby walkers, children's tricycles, children's electric cars, etc. The basic mechanism of the stroller is the frame and the roller device; the rotation of the roller device enables the stroller to move forward; in order to avoid the inertia of the rollers and cause it to always move forward, it is necessary to install a brake mechanism on the roller device. [0003] The existing brake mechanism is to clamp the brake disc installed on the main shaft of the roller through the brake parts. This brake mechanism will directly cause the brake disc to be clamped, and the pin will move the roller at a high speed to stop the rotation; it cannot play a buffering role; , the stroller was unst...

Problems solved by technology

[0003]The existing brake mechanism is to clamp the brake disc mounted on the main shaft of the roller through the brake parts. This brake mechanism will directly cause the brake disc to be clamped, and the pin The moving roller stops rotating; it cannot play a buffer role; it is easy to cause the stroller to be unstable when braking
