The invention discloses a four-wheeled electric truck convenient to swerve. The electric truck includes a frame, the bottom of the frame is provided with a storage battery, a motor and rear wheels, and the front end of the frame is hinged with a hinge frame; the front end of the hinge frame is fixedly welded with a swerving sleeve, a swerving column penetrates through the swerving sleeve and is rotatably installed, the upper end of the swerving column is fixedly provided a handlebar, and the two sides of the lower end of the swerving column are provided with two front wheels oppositely; a front wheel spacing adjustment device is connected between the two front wheels and the swerving column, and a connection supporting device is arranged between the front wheel spacing adjustment device and the swerving column. The structures of the handlebar, the swerving column and the swerving sleeve of the electric truck are simple, and through cooperation of the three, swerving of a truck body canbe achieved; besides, the distance between the two front wheels can be adjusted through the front wheel spacing adjustment device, a four-wheel truck can be changed into a three-wheel truck, the connection supporting device is used for supporting the two front wheels, through the structure, the swerving capacity of the truck body can be improved, force applied for swerving is small, and it is labor-saving and convenient to use.
Description
technical field [0001] The invention relates to the technical field of electric transport vehicles, in particular to a steering wheel device for electric transport vehicles that is convenient to operate and use in a greenhouse. Background technique [0002] With the development of greenhouse planting technology, the output of fruits and vegetables grown in greenhouses is getting higher and higher. In order to facilitate the transportation of fruits and vegetables or manage plants in greenhouses, and reduce the labor burden of growers, electric vehicles will be used for short-distance transportation. But the electric vehicle that uses in greenhouse is the electric vehicle of common structure at present, and structure is heavy and complicated. And the four wheels of the electric pallet truck are fixed and not adjustable, so the steering is not flexible. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a four-wheele...
