An obstacle-free carbon-free car that walks in the shape of "∽"

Abstract

The present invention relates to an obstacle-free carbon-free trolley with a "∽" shape walking. The potential energy bracket 4 is installed with a wire wheel bracket 3 and a secondary fixed pulley 1 through a wire wheel shaft 14. The front wheel bracket 6 is installed with a front wheel 7 through a front wheel steering shaft. Drive wheel 20 and driven wheel 11 are installed on the drive shaft 16, pinion 12 is installed on the drive shaft 16, bull gear 13 and small pulley 17 are installed on the bobbin shaft 14, and large pulley 18 is installed on the axle that is connected with crank connecting rod 9. The small gear 12 meshes with the large gear 13, the small pulley 17 is connected to the large pulley 18 through the belt 19, one end of the wire rope 22 is connected to the potential energy block 2, the wire rope 22 is wound around the secondary fixed pulley 1 and wound in the winding groove 15, and the wire rope 22 The other end of the pin is positioned through the wire hole on the secondary fixed pulley 1. The invention utilizes the falling potential energy of the potential energy block to convert into the kinetic energy of the trolley, and through gear meshing and belt transmission, the trolley avoids obstacles periodically and remotely according to a predetermined track, and the structure is simple and convenient.

Description

technical field [0001] The invention relates to a carbon-free trolley, in particular to an obstacle-free carbon-free trolley that travels in a "∽" shape. Background technique [0002] Such as 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 (drop height 400mm) into mechanical energy and can be used to drive the trolley to walk and turn. The carbon-free car adopts a stable structure with three wheels, which can automatically avoid obstacles on the road ahead when moving forward. (The distance between two obstacle stakes is 700-1300mm, and the specific distance is determined by lottery at the competition site). The biggest advantage of the carbon-free car is that it uses gravitational potential energy as the only energy, realizing carbon-free in the true sense.

Problems solved by technology

[0003] The driving mechanism of some trolleys 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 trolley, and the distance traveled by the trolley is controlled; some trolley wheels use fixed pulleys, so that heavy objects The fall is relatively fast, and the trolley is easy to overturn when turning; some trolleys are not very accurate in adjustment and cannot meet the requirements of cycle and amplitude; some mechanisms are relatively heavy, which not only increases the mass of the trolley itself, but also increases energy during the movement process. attrition, making it impossible to complete the race
