AI Technical Summary

Technical Problem

The rocker arm mechanism of existing electric motorcycles cannot continue to move after the rear wheel goes flat or blows out, and it is difficult to push it by hand, which leads to further damage to the wheel hub.

Method used

A rocker arm mechanism was designed, comprising a rocker arm body, a support base, a rotating component, and a power component. When the rear wheel is deflated or blows out, an auxiliary wheel is driven by an electric push rod to replace the rear wheel support. The angle between the inclined surface and the plane of the support base is used for limiting the position. The auxiliary wheel cooperates with the shock absorber box to achieve stable support, and shock absorption is achieved through the buffer groove and spring during collision.

Benefits of technology

It provides stable support for the auxiliary wheel in the event of a rear wheel failure, allowing the vehicle to continue driving, reducing wheel hub damage, and can be flexibly reset when not in use. It also has a shock absorption function, improving the practicality and flexibility of the device.
