Automatic damping deceleration carbon-free trolley based on rack method

Abstract

The invention discloses an automatic damping deceleration carbon-free trolley based on a rack method. The trolley comprises a frame, a big gear and a small gear engaged with each other and installed on the frame, a potential energy transmission mechanism for driving the big gear to rotate and an automatic damping deceleration mechanism, wherein the automatic damping deceleration mechanism comprises a rack outer sleeve, a treaded sleeve component and a rack installed in the rack outer sleeve; a spring and a damping block are arranged in the threaded sleeve component, a convex surface is arranged at the left end of the damping block; teeth and a U-shaped concave surface are arranged on two opposite side surfaces of the rack, the teeth are engaged with the small gear, and the U-shaped con cave surface is in contact with the convex surface of the damping block in an arc surface contacting manner. According to the automatic damping deceleration carbon-free trolley provided by the invention, the condition that both the movement speed of the carbon-free trolley during downhill and the weight dropping speed are effectively controlled by damping, so that the damping deceleration effect is formed, and the purpose of automatic damping deceleration is achieved; and the problems of driving direction shifting and rollover caused by speed loss when the trolley avoids obstacles during downhill are effectively solved.

Description

technical field [0001] The invention relates to the structure and control of a carbon-free trolley, in particular to an automatic damping deceleration carbon-free trolley based on a rack method. Background technique [0002] With the improvement of people's awareness of energy conservation and environmental protection, the carbon-free concept of cleaner, more environmentally friendly, more energy-saving and more efficient has been pushed into a research boom. The carbon-free trolley is a mechanical device that realizes drive and direction control based on gravitational potential energy. The concept of the trolley is ingenious. First of all, it is necessary to fully consider issues such as appearance and cost under the requirements of the design to facilitate subsequent expansion and further research and development; secondly , the current "S" and "8"-shaped carbon-free cars that run around piles do not have the ability to climb, and cannot meet the automatic adjustment of th...

The carbon-free trolley is a mechanical device that realizes drive and direction control based on gravitational potential energy. The concept of the trolley is ingenious. First of all, it is necessary to fully consider issues such as appearance and cost under the requirements of the design to facilitate subsequent expansion and further research and development; secondly , the current "S" and "8"-shaped carbon-free cars that run around piles do not have the ability to climb, and cannot meet the automatic adjustment of the required driving force on the up and down slopes, which can easily cause the car to stall when going downhill. The occurrence of direction drift and rollover seriously affects the technical performance and obstacle avoidance ability of the car
