Stroller frame with function of automatically locking and releasing rear wheels by body sensing

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.

Description

technical field [0001] The invention relates to a frame of a stroller, in particular to a frame of a stroller which utilizes human body induction to automatically lock and release rear wheels. Background technique [0002] The traditional stroller must be locked by the user's hands or by stepping on it, but sometimes it is inevitable that the lock is not complete, causing the stroller to slide down the slope or walk on its own. Be careful not to lock the wheels before letting go. At this time, the stroller is likely to slide to the driveway or fall into the ditch on the side of the road with the baby in the car, which is quite dangerous. [0003] At present, baby strollers are equipped with pedals on the left and right rear wheels, and cogs are provided on the pedals to embed the teeth of the rear hub to prevent the rear wheels from rotating; If you only step on one side of the pedal in an emergency, it will cause the baby carriage to shake and rotate, and there is a risk o...

[0002] The traditional stroller must be locked by the user's hands or by stepping on it, but sometimes it is inevitable that the lock is not complete, causing the stroller to slide down the slope or walk on its own. Be careful if you forget to lock the wheels and then let go. At this time, the stroller may slip into the driveway or fall into the ditch on the side of the road with the baby in the stroller, which is quite dangerous.

[0003] At present, baby strollers are equipped with pedals on the left and right rear wheels, and cogs are provided on the pedals to embed the teeth of the rear hub to prevent the rear wheels from rotating; If you only step on one side of the pedal in an emergency, it will cause the baby carriage to shake and rotate, and there is a risk of the car body tipping over or the baby in the car falling out and being injured
