Embodiment 1

[0026] See figure 1 , The embodiment of the present invention provides an electric tricycle, including a base plate 1 , a faucet 2 , a front wheel 3 , a rotating shaft 4 and two rear wheels 5 . The faucet 2 is installed on one end of the base plate 1, and the front wheel 3 is installed below the faucet 2 and connected to the faucet 2. Two handlebars 6 are installed on the end of the faucet 2 away from the front wheel 3, and the two handlebars 6 are respectively located on both sides of the faucet 2, which are used to facilitate the staff to operate the electric tricycle and control the driving direction of the electric tricycle. The rotating shaft 4 is installed below the base plate 1, and the two rear wheels 5 are installed at the two ends of the rotating shaft 4 respectively. In this embodiment, two ends of the rotating shaft 4 are covered with a sleeve (not shown) adapted to the rotating shaft 4, and the sleeve is connected to the bottom of the bottom plate 1 by welding. ...

Abstract

The invention discloses an electrically operated tricycle, and relates to the field of tricycles. The electrically operated tricycle includes a base board, a headstock, a front wheel, a rotating shaftand two rear wheels. The headstock is installed at one end of the base board, and the front wheel is installed below the headstock and connected with the headstock. The end, away from the front wheel, of the headstock is provided with a handlebar. The rotating shaft is installed below the base board. The two rear wheels are installed at the two ends of the rotating shaft correspondingly. A powermodule and a driving motor which are connected are further installed below the base board. An output shaft of the driving motor is connected with the rotating shaft. The front wheel and the rear wheels are all solid tires. Each solid tire includes a tire surface, a transition layer and a tire body which are connected from the outside to the inside in sequence. The electrically operated tricycle isbetter in wear-resisting property, puncture resistance and cutting resistance, lower in rolling resistance and longer in service life.

Description

technical field [0001] The invention relates to the technical field of tricycles, in particular to an electric tricycle. Background technique [0002] Electric tricycles have the advantages of strong applicability, flexible maneuverability, simple maintenance, convenient maintenance, and low price, and can flexibly travel between narrow roads. The electric tricycle has a reversing switch, which can conveniently realize the reverse driving function, which is very practical in narrow alleys and alleys, and it is very convenient whether driving or parking. It is widely used in short-distance transportation fields such as households, urban and rural areas, individual rental, factory areas, mining areas, sanitation, and community cleaning. [0003] However, when the electric tricycle is transporting heavy goods, the heavy objects are oppressed and the road surface is uneven, and the tires are often worn severely, which causes the tires to be easily damaged and have a short servi...
