Problems solved by technology

[0002] At present, most of the children's vehicles are children's tricycles. When children's tricycles are used, children need to step on the front pedal, which is difficult to use and easily causes children's fatigue; moreover, children use the way of riding, which makes the thighs and the seat constantly rub against each other. The car seat squeezes the lower body, which is harmful to the body
In addition, most children's tricycles adopt the form of setting two wheels at the back, and the brackets of the two wheels at the back are fixed on the body and cannot rotate relative to the body. Therefore, the plane where the rear wheels are located is always parallel to the extension direction of the body. Very inconvenient, inflexible turning

Abstract

The invention relates to a trolley for entertainment. The trolley comprises a seat frame, a headstock and a connecting piece, wherein the back end of the connecting piece is connected with the seat frame; the front end of the connecting piece is hinged with the headstock; left and right sides of the headstock are respectively provided with pedal parts; the lower end of the headstock is provided with M front pulley assemblies; the lower end of the seat frame is provided with N rear pulley assemblies, wherein the sum of M and N is more than or equal to 3; each front pulley assembly comprises a front pulley and a front pulley bracket; the front pulley bracket is connected with the front pulley; the front pulley bracket is connected with the headstock; each rear pulley assembly comprises a rear pulley and a rear pulley bracket; the rear pulley bracket is fixedly connected with the rear pulley; the rear pulley bracket is connected with the seat frame; the front pulley bracket or / and the rear pulley bracket is / are obliquely arranged; and when N is more than 1, the lower end of the seat frame is provided with a tail swinging device. The trolley is driven by a sitting posture so that the trolley is very comfortable to use; and meanwhile, the tail swinging device is arranged between the seat frame and the rear pulley assemblies, so that the deflection angle of the rear pulleys is reduced, and the trolley is good for steering and keeping the trolley balance.
