Power-assisted propulsion system and propulsion assisted vehicle

Abstract

The invention discloses a power-assisted propulsion system and a propulsion assisted vehicle, wherein the power-assisted propulsion system comprises a stress detection module, a signal processing module, a driving module a speed sampling module and a motor; the stress detection module is connected with a signal processing module; the signal processing module is also connected with a motor through the driving module; one end of a speed sampling module is connected with the motor, and the other end of the signal sampling module is connected with the signal processing module, wherein the stress detection module detects magnitude and direction of external push force into a first electrical signal; the signal processing module outputs a control signal according to the first electrical signal and the second electrical signal and controls the speed and direction of the motor through the driving module. The technical scheme can improve speed regulating performance of the power-assisted propulsion system.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to an electric auxiliary propulsion system and a push cart. Background technique [0002] Mobile medical X-ray imaging systems are mostly used in places where patients are inconvenient to move, such as bedsides and intensive care units, and need to move flexibly in wards, elevators or other environments with narrow roads. However, due to the high degree of integration of the mobile medical X-ray photography system itself, the overall weight is relatively large, and it is very difficult to push it by manpower. Most of the mobile X-ray imaging systems currently used in hospitals do not have power-assisted propulsion functions, or only have a single-speed power boost function. In actual use, it is difficult for staff to push the equipment flexibly, and often the equipment collides with the hospital bed. Obstacles such as doors or walls may cause damage to the equipment; it m...

However, due to the high degree of integration of the mobile medical X-ray photography system itself, the overall weight is relatively large, and it is very difficult to push it by manpower.

Most of the mobile X-ray imaging systems currently used in hospitals do not have power-assisted propulsion functions, or only have a single-speed power boost function. In actual use, it is difficult for staff to push the equipment flexibly, and often the equipment collides with the hospital bed. Obstacles such as doors or walls may cause damage to the equipment; it may also cause the equipment to collide with doctors or patients, causing personal injury
