AI Technical Summary

Technical Problem

Existing step pedals take up a lot of space when installed on vehicles, affecting their adaptability.

Method used

Design a linkage assembly including a fixing member, a first link, a second link, and a pedal link. The assembly is hinged to a bending part by a self-locking member to form a frame structure. In the self-locking position, the self-locking member is collinear with the second extension to prevent jamming and reduce space occupation.

🎯Benefits of technology

It improves the stability and space utilization of the linkage assembly, makes better use of the limited space in the vehicle, and enhances structural adaptability.

Abstract

A link assembly (100), a step device (200) and a vehicle, which relate to the technical field of vehicle components. The link assembly (100) comprises a fixing member (110), a first link (120), a second link (130), a step link (140) and a self-locking member, wherein one end of a fixing portion (111) of the fixing member (110) is connected to a second extension portion (113); one end of the first link (120) is articulated to the fixing portion (111); one end of the second link (130) is articulated to the end of the fixing portion (111) away from a first extension portion (112); and the end of the self-locking member away from the first link (120) is articulated to a bent portion (114), such that a protruding structure is formed on the bent portion (114) facing the self-locking member. When the link assembly (100) is in a first self-locking position, the self-locking member and the second extension portion (113) are arranged collinearly. The stability of the link assembly (100) is improved by providing the first self-locking position.
