Combined vehicle, combined units and combined connector thereof

Abstract

The invention relates to a combined vehicle, combined units (1 and 2) and a combined connector (4) thereof. Either combined unit of the combined vehicle comprises a vehicle body frame and two wheels (6) respectively mounted in parallel on a left axle fixing plate and a right axle fixing plate of the vehicle body frame; and parallel transmission rods (14) with gears are mounted on a bearing frame (16) at the bottom of the vehicle body frame and drive flywheels or gears on the two wheels (6) to rotate by chain transmission. Connecting plates (7 and 8) for connecting with the combined connector (4) are respectively arranged in the front or / and at the rear of the vehicle body frame, and the combined connector (4) comprise a fixed connecting plate, a direction steering shaft capable of rotating relatively to the fixed connecting plate, an upper-and-down sliding shaft and a movable connecting plate capable of rotating around the upper-and-down sliding shaft. The combined connector can rapidly adopt a tread driving mode and a power driving mode of the combined vehicle formed by combining at least two combined units and is easy and economic, random to use, convenient to stop, suitable for city and countryside and convenient for the public to grasp.

Description

technical field [0001] The present invention relates to a combination unit of a combination vehicle, the combination unit is mainly composed of a vehicle body frame and two wheels; the invention also relates to a combination connector and a combination vehicle using the combination connector to combine at least two combination units together . Background technique [0002] The British have invented bicycles for more than 150 years. The rapid development of electric bicycles has proved that the simple, convenient and environmentally friendly design of bicycles is suitable for future development. But the structure of each round before and after the bicycle is not stable when in use, so that some people can't use it, and some people dare not use it, especially when using the saddle for a long time, it is easy to make people tired. Though the design of four-wheeled bicycle is arranged in recent years, as can refer to Chinese utility model patent description ZL00202924.3 and ZL0...

AI Technical Summary

Problems solved by technology

However, the structures of the front and rear wheels of the bicycle are not stable during use, so that some people can't use them, and some people dare not use them, especially when using the saddle for a long time, it is easy to make people tired

Although the design of four-wheeled bicycle has been arranged in recent years, as can refer to Chinese utility model patent instruction ZL00202924.3 and ZL01238542.5, all because of various reasons such as volume, structure, function, price and the production equipment of parts, investment, be difficult to popularize

[0003] In addition, in the current means of transportation on land, the axles of carriages and trolleys are fixed on the car body with parallel wheels, but the wheels are passive wheels and cannot be used as driving wheels (that is, driving wheels); the rear wheels of bicycles can be used as driving wheels. , but the safety of the front and rear rounds is relatively poor; the tricycle is a single-wheel drive mode, with large resistance and small inertia; Large, high cost of use; trains need special tracks, and they have to go up and down at fixed times and places, and they cannot be used for random travel
