AI Technical Summary

Technical Problem

Traditional end caps experience concentrated stress when subjected to radial and reverse torque impacts, which can easily lead to structural deformation or failure. They are unable to meet the high-strength requirements under complex working conditions and have insufficient sealing performance.

Method used

The structure employs a combination of limiting grooves and limiting protrusions, and connects the end cover and gearbox assembly with fasteners to disperse stress and add double sealing grooves, forming three-dimensional constraints and multi-directional limiting, thereby optimizing structural stability.

Benefits of technology

It improves the impact resistance and structural stability of the end cap, prevents deformation and sealing failure, and adapts to the reliability and sealing performance under high-frequency impact scenarios.

Abstract

The application discloses a module motor end cover assembly structure, a module motor and a foot-type robot. The module motor end cover assembly structure comprises a gear box assembly and a ring-shaped end cover. A limiting groove is arranged on the end cover, a limiting protrusion corresponding to the limiting groove is arranged on the gear box assembly, a connecting hole through which a fastener can pass is arranged on the bottom wall of the limiting groove and the limiting protrusion corresponding to the limiting groove, and the end cover and the gear box assembly are connected through the fastener. Through the cooperation of the limiting groove and the limiting protrusion and the design of the connecting hole and the fastener, stress dispersion and multidirectional limiting are realized, and the impact resistance and the structural stability are improved.
