Problems solved by technology

[0003] However, the lock in this vehicle frame retractable device is not stable for the locking of the vehicle frame when the vehicle frame is opened. When an accidental collision or moving the vehicle frame / seat, it is very likely that the front foot will be released due to the movement of the lock. , the lock between the rear foot and the handlebars, allowing the frame to fold inadvertently

Abstract

A secondary locking mechanism 14 for locking a locking part of a locking mechanism in a collapsible frame (100 figure 1) includes a casing 232, an engagement part 41, a manipulation part 42a, and an elastic part (43 figure 3b). The engagement part is pivotally connected to the casing. When the frame expands, the engagement part abuts against the locking part to lock the locking part. The manipulation part is connected to the engagement part and partially exposed out of the casing. The manipulation part is operable to control motion of the engagement part for disengaging the engaging part from the locking part. The elastic part provides a restoring elastic force to the engagement part. Therefore, the secondary locking mechanism can perform secondarily locking effect for efficiently avoiding any unexpected folding to the frame. Various secondary locking mechanisms are disclosed, including ones where the manipulation part is pushed, pulled, or provided with a release tab. The secondary locking mechanism is particularly intended to safeguard a stroller frame from folding when not intended to.

Description

technical field [0001] The invention relates to a collapsible vehicle frame, in particular to a collapsible vehicle frame with a secondary locking mechanism therein. Background technique [0002] In order to facilitate placement and transportation, the current frame or seat is equipped with a frame folding device, through which the front and rear feet of the frame or seat can be folded together, so that the frame or seat Folding up saves space and is convenient for transportation. However, in order to prevent accidental folding during use, the frame folding device includes a front foot, a rear foot, a handle, a first locking mechanism and a second locking mechanism, and one end of the front foot is fixed with a One end of the first rotating member and the rear foot is fixed with a second rotating member, and one end of the handle is fixed with a third rotating member, the first rotating member and the second rotating member are pivotally connected by a first rotating shaft, ...
