Abstract
A brake mechanism includes a first wheel base, a second wheel base, a linkage part, a passive brake device and an active brake device. The first wheel base and the second wheel base are installed on two feet of a stroller, respectively. A first wheel set and a second wheel set of the stroller are pivotally connected to the first wheel base and the second wheel base, respectively. The passive brake device and the active brake device are connected to a first end and a second end of the linkage part, respectively. The active brake device includes a first engaging part and a driving part. The driving part is rotatably disposed on the second wheel base. When the driving part rotates between a locking position and a releasing position, the driving part drives the first engaging part and drives the passive brake device to move via the linkage part.
