"∽" shaped carbon-free car

Abstract

The invention discloses a carbon-free cart for traversed S-shaped traveling. A front wheel (14) is installed on a front wheel bracket (6) through a front wheel steering shaft (5), a dead pulley (1) is installed on a potential energy bracket (3), a driving shaft (15) is installed on a driving shaft bracket (16), a driving wheel (17) and a driven wheel (8) are installed on the driving shaft (15), left and right pinions (18, 19) are installed on the driving shaft (15), left and right gear wheels (11, 10) are installed on a bottom frame (13), the left and the right pinions (18, 19) are engaged with the left and the right gear wheels (11, 10), a rope (4) for connecting a potential energy block (2) is wound on the left gear wheel (11) bypassing the dead pulley (1), and two ends of a connecting rod (9) are respectively connected with the right gear wheel (10) and the front wheel steering shaft (5). In the invention, potential energy generated in the falling process of the potential energy block is utilized as kinetic energy to push the cart to move forwards, and barriers arranged on a track can be automatically avoided according to a certain period and long distance during advancing.

Description

technical field [0001] The invention relates to a trolley, in particular to a carbon-free trolley that travels in a "∽" shape. Background technique [0002] like figure 1 As shown, it is required to give a gravitational potential energy, according to the principle of energy conversion, design a mechanical device that can convert the gravitational potential energy (the drop height is 500mm) into mechanical energy and can be used to drive the trolley to walk and turn. The self-propelled car can automatically avoid obstacles set on the track when moving forward (every 1 meter, place an elastic obstacle round bar with a diameter of 20mm and a height of 200mm), such as figure 2 shown. [0003] According to the known data of the existing carbon-free racing car model, it has many not-so-perfect places. First of all, its driving mechanism is to wind the traction rope directly on the drive shaft, so its starting torque is small, which is not conducive to the starting of the t...

AI Technical Summary

Problems solved by technology

First of all, its driving mechanism is to wind the traction rope directly on the drive shaft, so its starting torque is small, which is not conducive to the start of the car, and the distance traveled by the car is controlled

Secondly, its steering mechanism is controlled by the crank swing mechanism, the left and right tensioning rope pulleys and the tensioning rope. It is very inconvenient to operate when winding the tensioning rope and debugging, and its mechanism is placed on the front end of the trolley frame. The center of gravity of the car is unstable and it is easy to roll over

In the end, except for the frame, the processing costs of the other parts of the small car are relatively high, which does not meet the requirements of no carbon and low cost in the competition.
