AI Technical Summary

Technical Problem

The existing friction transmission structure between the wheel rim and tire of toy cars is prone to friction coefficient decay due to material stress relaxation, micro-wear and surface aging under long-term dynamic load, resulting in a decrease in torque transmission capability.

Method used

The design incorporates anti-slip protrusions and anti-slip grooves, which enhance mechanical meshing force and increase contact area to ensure torque transmission by forming a physical fit and interlocking mechanism between the wheel rim and tire bead.

Benefits of technology

It effectively overcomes the shortcomings of relying solely on friction transmission, ensuring reliable torque transmission between the rim and tire under long-term dynamic load, avoiding excessive wear, and improving anti-slip performance.

Abstract

The utility model relates to a kind of toy moving device and toy car, and toy car is provided with toy moving device.In toy moving device, by setting mutually adaptive anti-skid convex part and anti-skid profiling groove structure, and make it be located on wheel frame and bead respectively, on the basis that bead is supported in wheel frame, further formed the physical inlay and interlocking mechanism between wheel frame and bead.Consequently, it significantly enhances the mechanical meshing action force between wheel frame and bead in circumferential and / or axial direction, fundamentally overcomes the inherent defects of simply relying on friction transmission, ensures that rim and tire can still reliably transmit torque under long-term dynamic load.Secondly, the mutual adaptation of anti-skid convex part and anti-skid profiling groove on profile can increase the contact area of rim and bead, so that stress transmission can be carried out through larger area, to avoid excessive wear between rim and tire due to stress concentration, thereby further consolidating the anti-skid effect.
