Abstract
A stroller frame with an automatic brake mechanism actuatable by hand detecting includes at least a first rear wheel, a first locking mechanism, a second rear wheel, a second locking mechanism, a battery and a hand-detecting handle. The hand-detecting handle is capable of detecting the caregiver's hand by a change of capacitance on its surface, generating a first control signal to a power supply circuit when the caregiver's hand is near, and generating a second control signal to the power supply circuit when the caregiver's hand is absent. The power supply circuit may provide currents in different direction to the first locking mechanism and the second locking mechanism according to the first control signal and the second control signal, so as to lock the rear wheels once the caregiver's hand has left the hand-detecting handle, and unlock the rear wheels when the caregiver's hand near the hand-detecting handle automatically.
