A link mechanism folding vehicle

Abstract

The invention relates to a link mechanism folding vehicle which comprises an automobile chassis, a carriage, hydraulic oil cylinders, link mechanisms and a telescopic guide rail. The carriage comprises a first carriage body and a second carriage body and is installed on the automobile chassis, and the first carriage body and the second carriage body are connected through the link mechanisms. Eachlink mechanism comprises a front connecting board, a rear connecting board, a third-pair component and a second-pair component. The front connecting boards are installed on the first carriage body, the rear connecting boards are installed on the second carriage body, round pin holes are formed between the front connecting boards and the rear connecting boards, and the front connecting boards and the rear connecting boards are hinged through the third-pair components and the second-pair components. Bases of the hydraulic oil cylinders are installed on the two side faces of the first carriage body. The telescopic guide rail is installed in the middle position between the automobile chassis and the first carriage body. The link mechanism folding vehicle has the beneficial effects that the carriage can be folded and can stretch and retract level by level, the occupied space is small, operation is automatic, easy and convenient, the folding range is large, carrying is convenient, the safetycoefficient is high, and the influence of the folding process on the vehicle body stability is small.

Description

technical field [0001] The invention belongs to the field of special vehicle design and relates to a folding vehicle with a link mechanism. Background technique [0002] Automobile transportation is an important mode of cargo transportation, and it is the most important form of short-distance transportation in my country at present. At present, the transportation of many goods such as steel and timber is very one-way, so the phenomenon of empty cars often occurs, which causes the waste of transportation resources and the unreasonable use of transportation space; at the same time, due to the The volume of the car is generally relatively large, and the stability of the empty car is poor, it is inconvenient to drive, and it is easy to cause safety accidents; the volume is too large, the unreasonable use of space will cause energy waste, and it does not meet the requirements of energy saving and emission reduction. [0003] The patent document CN201620573220.8 discloses a trans...

Problems solved by technology

This patent folds the conveyor belt when it is not in use, but when folding, the conveyor belt is lifted by a lifting device, and the conveyor belt is folded through the rotation of the positioning pin. The folding process is complicated, and other devices are needed when folding, which is not conducive to the structure. Simplified, time-consuming and labor-intensive, folding requires too much human participation, and does not conform to the trend of automation

[0005] Therefore, the market urgently needs to design a multifunctional transport vehicle that can be folded automatically and efficiently to solve the problems of insufficient transport capacity of ultra-long trucks, too much space when empty, and low operating efficiency.
