Problems solved by technology

Since the user's center of gravity changes synchronously when the user switches from a sitting position to a standing position or from a standing position to a sitting position, the traditional crutches have a fixed length when used, and the length of the crutches cannot be changed in time to improve Adapt to the change of the center of gravity of the user, thus making it easy for the crutch user to fall and be injured due to improper measures taken by the change of the center of gravity
It is the most difficult for crutch users to change from sitting to standing or from standing to sitting. Traditional crutches cannot adjust the length in time to adapt to the change of the center of gravity, and at the same time cannot provide corresponding assistance. Pain points

Abstract

The invention discloses a power-assisted walking stick which is composed of a handle, a fixed rod, a movable rod, a motor, a power line, a lifting switch, a battery, an external thread screw rod and a fixing piece with an internal thread hole, and is characterized in that the motor is powered by the battery, the kinetic energy of the movable rod is derived from the external screw rod, and the kinetic energy of the external thread screw rod is from the motor; the length of the walking stick is adjusted by driving the external thread screw rod through the motor, and meanwhile, the walking stick user is assisted to switch from a sitting posture to a standing posture or from the standing posture to the sitting posture by utilizing the lifting power, so that the user can sit or stand more easily and safely.

Description

technical field [0001] The invention relates to a power-assisted crutch, in particular to a crutch which can provide power assistance and timely adjust the length when a user changes from a sitting posture to a standing posture or from a standing posture to a sitting posture. Background technique [0002] Crutches provide support when the user transitions from a sitting to standing position or vice versa. Since the user's center of gravity changes synchronously when the user switches from a sitting position to a standing position or from a standing position to a sitting position, the traditional crutches have a fixed length when used, and the length of the crutches cannot be changed in time to improve Therefore, it is easy for crutch users to fall and get injured due to improper measures taken by the change of the center of gravity. It is the most difficult for crutch users to change from sitting to standing or from standing to sitting. Traditional crutches cannot adjust th...
