AI Technical Summary

Technical Problem

The driving force receiving parts of existing laser printers are easily damaged during engagement, resulting in damage to the brake claws and affecting the accurate control of the photosensitive drum assembly.

Method used

A driving force receiving member with a simple structure is designed, including a base, a convex column, a barrier portion and a rib strip. The gap between the driving member and the brake claw is inserted through the rib strip, so as to achieve engagement with the driving force output device, and prevent improper engagement through the barrier portion.

Benefits of technology

Reliable engagement between the driving force receiving member and the driving force output device is realized, which reduces production costs and avoids the problem of damage to the brake claws, ensuring accurate control of the photosensitive drum assembly.

Abstract

The invention provides a driving force receiving member, a photosensitive drum assembly and a process cartridge, the driving force receiving member comprises a base, one end of the base is provided with a convex column, and the axial end of the convex column is provided with a positioning hole; at least one blocking part and at least one rib are arranged on the periphery of the convex column, the number of the blocking part is equal to that of the rib, a driving force receiving surface is formed on the first side of the rib in the circumferential direction of the base, and a braking force receiving surface is formed on the second side of the rib; gaps are formed between the blocking parts and the adjacent ribs on the periphery of the protruding column in the circumferential direction of the base. The driving force receiving piece is arranged at the end part of the photosensitive drum assembly. The processing box is provided with the photosensitive drum assembly. The driving force receiving piece is simple in structure, does not need to be assembled, is low in production cost, and can be reliably meshed with the driving force output device.
