Description

Baby stroller synchronous brake structure

technical field

The utility model relates to a synchronous braking structure, in particular to a synchronous braking structure applied to baby carriages which utilizes a pedal to synchronously brake or release the brakes on both sides of the wheels.

Background technique

There are many kinds of brake mechanisms currently used in baby strollers. The common one is to set a pedal separately on the left and right rear wheels. The cogs fit into the brake cogs of the rear wheel, thereby braking the rear wheel. The control mechanism of this type of brake is carried out separately on the left and right sides, which is troublesome to operate, especially in an emergency situation, when the rear wheels on both sides cannot be braked at the same time, it will cause the trolley to shake, spin or fall, causing the baby to fall. Fall and hurt. This brake mechanism, which cannot be synchronized between the left and the right, is still applied to slow-moving baby strollers, or baby strollers traveling on smooth roads, etc. at present. For driving at a higher speed or when driving on a steeper slope, based on safety considerations, it is important to brake the two rear wheels synchronously. Taking the UK as an example, they have included one pedal and two brakes on baby carriages as a safety standard.

Therefore, it is necessary to invent a synchronous braking structure applicable to baby carriages to solve the above problems.

1-3, the operator can use the brake pedal 5 to control the synchronous braking or synchronous release of the brakes on the left and right wheels. The synchronous braking structure of the stroller in this embodiment is combined with a frame 10 of the stroller. Wherein the stroller frame 10 has an unfolded state and a folded state. In this embodiment, it can be a frame 10 folded longitudinally, including a leg tube 11 (including a front leg tube and a rear leg tube).

The synchronous braking structure of the stroller in this embodiment includes a pair of wheel bases 2 , a linkage rod 4 , a brake pedal 5 , a driving member 6 , a brake ring 7 and an elastic component 8 .
