Carbon-free toy car of 8-shaped track

Abstract

The invention relates to a carbon-free toy car of a 8-shaped track. The toy car comprises a driving part, a steering part and a transmission part; the toy car can cross obstacles in the 8-shaped track; during operating, a weight is put down, and gravitational potential energy generated from the weight during dropping is transmitted to a spool by virtue of twin wheels; by virtue of a gear on the spool, power is transmitted to a rear axle and a cam; the car is advanced by virtue of the rear axle, and meanwhile, a connecting rod is driven by the cam, so that a front wheel periodically swings left and right along with a rocker; therefore, the car can advance along the 8-shaped track; by virtue of a micro-adjustment mechanism and a transmission ratio adjustment mechanism, various tracks can be offered to adapt to obstacles at different distances; the toy car disclosed by the invention is environment-friendly and carbon-free, compact in structure, relatively low in cost, relatively low in dependency on fields, and strong in interesting and competitive character; and the toy car is beneficial for enriching the knowledge and widening the horizons of teenagers, developing the practice and thought abilities of the teenagers and improving the comprehensive qualities of the teenagers.

Description

technical field [0001] The invention discloses an "8"-shaped track obstacle-surmounting device, in particular to a carbon-free toy car capable of moving around a pile in a figure-8. Background technique [0002] In 1982, Japan reduced the radio remote control racing car for professional competition, removed the steering and remote control device, and successfully manufactured the first miniature four-wheel drive racing car, which attracted thousands of teenagers. The development of four-wheel drive vehicles in China is also in the ascendant. In the early 1990s, Audi Toys Industrial Co., Ltd. imported technology from Japan and began to produce a series of four-wheel drive vehicles. In just a few years, four-wheel drive vehicles became popular throughout China. Because of their strong interest, they are still popular in the 21st century. The majority of young people love, the general four-wheel drive toy car is mostly driven by a motor, that is to say, it needs to install a b...

Problems solved by technology

In the early 1990s, Audi Toys Industrial Co., Ltd. imported technology from Japan and began to produce a series of four-wheel drive vehicles. In just a few years, four-wheel drive vehicles became popular throughout China. Because of their strong interest, they are still popular in the 21st century. The majority of young people love, the general four-wheel drive toy car is mostly driven by a motor, that is to say, it needs to install a battery. Although this kind of toy car has a certain degree of interest, it is not energy-saving, environmentally friendly and economical because it needs to be driven by electricity. , and it needs to be equipped with a special track, which is more dependent on the environment
