Description

Technical Field

[0001] The utility model relates to a unicycle with electric assist. Background Art

[0002] A wheelbarrow is a common transportation tool. Compared with ordinary multi-wheel wheelbarrows, a unicycle wheelbarrow has a simple structure and a small volume, so it is widely used in aspects of production and life, such as the warehousing industry, the construction industry, etc. Traditional unicycle wheelbarrows rely on manual pulling or pushing, resulting in high labor intensity and low work efficiency. Thus, an electric unicycle wheelbarrow came into being, providing power for the unicycle wheelbarrow through a drive motor.

[0003] In current electric unicycle wheelbarrows, the drive motor is integrated in the electric walking wheel, simplifying the overall structure of the electric unicycle wheelbarrow. However, the frame, legs, and handle are welded together, which still needs to be improved. Summary of the Utility Model

[0004] One technical problem to be solved by this application is to overcome the defects of the above-related technologies and provide an electric unicycle with electric assist having a simpler structure.

[0005] The technical solution adopted by the utility model to solve the technical problem is as follows: An electric unicycle with electric assist includes a cart body, a frame, an electric walking wheel, a handlebar, and legs; the frame, legs, and handlebar are composed of two integral multi-folded rods. One ends of the two multi-folded rods are respectively fixed at both ends of the axle of the electric walking wheel. The bottom of the middle part of the √-shaped multi-folded rod is the leg. A support block for the bottom plate of the cart body is connected to the starting point of the straight section in the middle part of the √-shaped multi-folded rod. A connecting block for the rear wall of the cart body is connected to the straight section in the middle part of the √-shaped multi-folded rod. The tail end of the multi-folded rod is the handle.

[0006] Compared with the related technologies, the utility model has the following advantages: The frame, legs, and handlebar are composed of two integral multi-folded rods, reducing the number of parts, further simplifying the overall structure, and thus reducing the production cost.

[0007] Preferably, lamp brackets are connected to both ends of the axle of the electric walking wheel and are located in front of the cart body. Lighting lamps are fixed on the lamp brackets. The switch of the lighting lamp is integrated on a control member of the electric walking wheel beside a handle. The walking speed of the electric unicycle with electric assist is relatively fast, and lighting is required in an environment with insufficient light to prevent the electric unicycle with electric assist from colliding with obstacles and causing accidents.

[0008] Preferably, horns are arranged on both sides of the lighting lamp on the lamp bracket, and the buttons of the horns are also integrated on the control member. The walking speed of the electric unicycle with electric assist is relatively fast, and it is necessary to remind the people in front to pay attention and avoid in advance.

[0009] As an improvement, a plurality of angle steels are connected between the √-shaped middles of the two multi-folded rods. The angle steels are arranged under the bottom plate of the cart body, and a protection box is installed on the angle steels. The power supply and the control circuit board of the electric walking wheels are both installed in the protection box, which is used to protect both the power supply and the control circuit board, preventing the power supply and the control circuit board from being collided by the flying stones knocked.
