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.
