Benefits of technology

This patented technology allows for automatic locks on bicycles with an inductive person sensory system. It works like this: if someone tries to get their hands off your car or step outside while rushing towards it, they will trigger one button instead of just pressing them together. These buttons work together to prevent accidental slippage between these parts during use.

Problems solved by technology

This patented technical problem addressed in the current design for bicycle child carriages involves safety concerns when they shouldn’t have their wheel locks fully secured during use due to accidentally unlocking them while driving around corners at nighttime without leaving any obstacles like potholes or rocks underground.

Abstract

The invention discloses a stroller frame with function of automatically locking and releasing rear wheels by body sensing. The stroller frame comprises a frame body, a first wheel and a second wheel and is provided with a first locking mechanism, a second locking mechanism, a power source, and a body-sensing handle. When a user removes hands off from the body-sensing handle, the body-sensing handle sends out a second signal to allow the first locking mechanism and the second locking mechanism to simultaneously lock the rear wheels, so that a stroller is prevented from sliding along a slope to cause accidents; when the user touches the body-sensing handle again with the hand, the body-sensing handle sends out a first signal to allow the first locking mechanism and the second locking mechanism to simultaneously unlock the rear wheels, so that the stroller can be pushed directly.
