Passenger and freight dual-purpose low-speed electric vehicle

Abstract

The invention discloses a passenger and freight dual-purpose low-speed electric vehicle, belongs to the field of short-distance traffic, daily life article carrying and electric vehicles, is used for solving the problems of short-distance transportation and article carrying in family daily life and is characterized in that two side longitudinal beams, one to three inner side longitudinal beams and a plurality of auxiliary beams are connected to form a staggered vehicle frame, the inner side longitudinal beams extend forwards and are connected with a chassis vehicle frame which is 0.9-1.5 m in length, 0.5-0.7 m in width and 0.2-0.3 m in elevation, lower beams of the side longitudinal beams extend forwards to the middle of the chassis vehicle frame and are connected with the inner side longitudinal beams, and the rear part of the frame is a rear suspension with the height of 0.4-0.5 m; a steel plate is laid on the rear suspension to form a carriage chassis with the length of 0.5-1.5 m and the width of 0.8-1.2 m, a breast board is installed above the carriage chassis, a bow board or / and a spiral spring is installed below the carriage chassis, and the carriage chassis is connected with a rear axle and a rear wheel; a front seat frame is arranged in the middle of the chassis frame; the two sides of the rear end of a middle ring beam are connected with a portal frame, the middle of the rear end is connected with a rear suspension through a longitudinal connecting beam, and the lower portion of the rear end is connected with the chassis frame through supporting legs; a multifunctional area with the depth of 0.12-0.35 m is designed on the rear portion of the front seat frame, and the two sides of the multifunctional area are provided with fence doors with the length of 0.15-0.35 m and the height of 0.5-0.8 m. The device is suitable for passenger and cargo dual-purpose low-speed electro-tricycles and four-wheelers, and is particularly suitable for small and medium-sized towns and vast rural areas.

Description

technical field [0001] The invention belongs to the fields of short-distance traffic, conveyance of daily necessities and electric vehicles, and in particular relates to a dual-purpose low-speed electric vehicle for passenger and cargo. Background technique [0002] In the era of protecting the atmospheric environment and advocating green transportation, electric tricycles are simple in structure, cheap in price, easy to use, meet the requirements of short-distance handling of household daily necessities, and have low operation and maintenance costs, do not consume gasoline, and do not emit waste gas to pollute the environment. It is widely used in small and medium-sized towns and vast rural areas. At present, the main structure of the electric tricycle is a ladder-type bridge frame and an independent carriage. The width of the ladder-type bridge frame is 0.5-0.7m, including the front chassis frame and the rear suspension. The height of the front chassis frame from the groun...

AI Technical Summary

Problems solved by technology

At present, the electric tricycles on the market cannot meet the two requirements of cargo handling and personnel riding at the same time.

Some families have no choice but to buy two electric vehicles (recreational electric vehicles and electric three-wheeled trucks), one of which is often damaged due to low usage and long-term parking in the garage; perhaps funds and garage restrictions can only buy one car. Either it is difficult for people to ride, or it is difficult for cargo to be entangled

The electric four-wheel vehicle on the market does not have the dual function of carrying goods and taking people
