A carbon-free self-propelled trolley with reversing function

Abstract

The invention discloses a carbon-free self-propelled trolley with a reversing function. A four-connecting-rod mechanism and a joint bearing part are used to accurately control swing of a guide wheel fork so as to realize turning of a guide wheel, small torque and abrasion and accurate swing are achieved. Four rail rods are used to limit swing of a counter weight, so that tilting of the trolley during turning and coming up and down a slope can be avoided effectively. The carbon-free self-propelled trolley is driven to move by converting gravitational potential energy into kinetic energy, no fuel or electric energy is needed, no greenhouse effect gases such as carbon dioxide are emitted, and the carbon-free self-propelled trolley is low-carbon, environmental friendly, and simple to use. An operator can reverse a trolley drive wheel to hang a heavy object, namely converting mechanical energy into gravitational potential energy. The carbon-free self-propelled trolley can be used as physics demonstration experiment equipment for primary schools and middle schools, and students are allowed to better understand experiment energy conversion and application through specific instances.

Description

technical field [0001] The invention relates to a self-propelled trolley, in particular to a carbon-free self-propelled trolley with reversing function. Background technique [0002] The carbon-free self-propelled car drives the car by converting the gravitational potential energy into kinetic energy. It does not require energy such as fuel or electricity, and does not emit greenhouse gases such as carbon dioxide. Self-propelled cars generally provide driving energy through the elastic potential energy stored in batteries or coil springs, but because the batteries need to be replaced frequently, the cost of use is high, and at the same time it involves the problem of waste disposal, it will inevitably cause environmental pollution; After that, it needs to be replaced or repaired, shortening the service life of the self-propelled car and increasing the maintenance cost. The self-propelled trolley driven by the elastic potential energy stored in the coil spring has a very sho...

Problems solved by technology

[0005] In order to avoid the shortcomings of the existing technology and overcome the problem of inaccurate steering of the carbon-free trolley and easy to cause the trolley to overturn, the present invention proposes a carbon-free self-propelled trolley with reversing function, which adopts a four-bar linkage mechanism and joint bearing components Accurately control the swing of the guide wheel fork to realize the steering of the guide wheel, which has the characteristics of small torque, small wear and accurate swing; at the same time, four track rods are used to limit the swing of the weight, which can effectively prevent the trolley from turning and tipping when going up and down slopes
