[0002] Electric vehicles can be divided into three categories, according to a series of parameters such as maximum speed and overall weight: electric bicycles, electric mopeds and electric motorcycles. Electric two-wheeled motorcycles: two-wheeled motorcycles driven by electricity; the maximum design speed is greater than 50km / h. Electric three-wheeled motorcycles: three-wheeled motorcycles driven by electricity, with a maximum design speed greater than 50km / h and a vehicle curb weight not exceeding 400kg. Electric two-wheeled mopeds: two-wheeled motorcycles driven by electricity and meeting one of the following conditions: the maximum design speed is greater than 20km / h and not greater than 50km / h; the vehicle curb weight is greater than 400kg and the maximum design speed is not greater than 50km / h. Electric three-wheeled mopeds: three-wheeled mopeds driven by electricity, with a maximum design speed not greater than 50km / h and a vehicle curb weight not exceeding 400kg.

[0003] Rims suitable for motorcycles are designed according to motorcycle rims, with W-shaped and M-shaped cross-sections. No matter how they are manufactured, the cost is high. Light motorcycles have low speed and small vehicle weight, and the use of motorcycle rims will seriously exceed the demand, resulting in a waste of resources. Utility Model Content

[0004] The utility model aims to overcome technical deficiencies and provide an electric light motorcycle and a three-wheel rim with low cost and high comfort.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An electric moped and tricycle rim includes a rim body, a frame-shaped cross section, a cavity formed between the tire lip surface and the steel wire surface, and inclined reinforcing ribs symmetrically arranged inside the cavity. The reinforcing ribs separate the cavity into shaft sleeve cavities at both ends and a closed trapezoidal cavity in the middle. The reinforcing ribs on both sides are connected with the tire lip surface and the groove, and surrounded by the steel wire surface to form a closed trapezoidal cavity. The shaft sleeve cavity is formed by the reinforcing ribs on one side and the tire lip seat, double grooves, and an outer inclined surface. The design of the inclined reinforcing ribs and the trapezoidal cavity improves the lateral rigidity and radial rigidity of the rim. The shaft sleeve cavity is a cavity for inserting the shaft sleeve, and one wheel rim has two shaft sleeve cavities, one on each side.

[0007] Furthermore, both side walls are connected to the tire lip seats, and the tire lip seats are connected to the double grooves protruding from the center of the outward inclined surface. The double grooves are the tire installation positions, which reduce the tire pressure. At the same time, the design of one double groove on each side facilitates the installation of the tire.

[0008] Furthermore, the middle connection position of the double grooves is a groove connection, which is used to install the lining belt and reduce the size, and the installed lining belt forms a sealing state with the tire.

[0009] Furthermore, spoke holes are arranged at intervals on the trapezoidal cavity, and the size of the wire surface is slightly reduced compared with the size of a conventional motorcycle rim.

[0010] Furthermore, the spoke hole passes through the trapezoidal cavity, penetrates the steel wire surface and the slot connection. The hole located on the slot connection is a back hole, and the back hole is located between the two protrusions.

[0011] Furthermore, a hole through which 12G and 13G rear wheel copper heads can pass is arranged on the surface of the steel wire, and the hole is offset from the center of the cross section, specifically 0-2mm.

[0012] Furthermore, the outer bevel surface and the steel wire surface are integrally formed.

[0013] The designed wheel set of this application uses a front wheel steel wire ≥13G, and the rear wheel steel wire used to meet the load-bearing requirements is ≥12G to meet the load-bearing requirements.

[0014] The beneficial effects of the utility model are:

[0015] According to the use of the utility model, the low-cost vacuum tire rim is applied to the electric moped, which can achieve the comfort of the spoke wheel and solve the cost problem of the wheel set, thus achieving the combination of performance and comfort and promoting the development of vacuum tire spoke rims. The inner width of the rim is between 1.9 and 2.5 inches, and a wide outer tire can be installed to reduce tire pressure.

[0016] The double-layer design of the rim increases the rigidity of the rim by setting inclined reinforcing ribs in the cavity and the closed trapezoidal structure, allowing the rim to run normally. BRIEF DESCRIPTION OF THE DRAWINGS
