Swing-Arm Hook Mechanism for Foldable Shaft Cover Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fixing between the shaft cover and the base in foldable screen terminals is not firm, leading to potential warpage and deformation of the shaft cover, which affects the aesthetic appearance and can cause the shaft cover to fall off.
Innovation Solution
A hook mechanism is introduced, comprising a shaft cover, a base, and swing arms, with first and second mounting parts disposed on the shaft cover and swing arms respectively. When the swing arms are in the folded location, the mounting parts engage, applying tensile force to the shaft cover, ensuring it remains firmly connected to the base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the shaft cover is fixed to the base using screws or glue with reduced fixed points or large distances between fixed points, then the device complexity is reduced, but the connection strength becomes insufficient causing warpage and deformation
Solution Approach 1:
The swing arm is designed to rotate between unfolded and folded locations, dynamically changing the mounting configuration. When folded, the swing arm brings the second mounting part into engagement with the first mounting part, creating an active tensile force connection that supplements the static screw/glue fixation.
Solution Approach 2:
The swing arm acts as an intermediary component between the shaft cover and base. It transfers and applies tensile force to the shaft cover when in the folded location, enhancing the connection without requiring direct multiple fixed points between the shaft cover and base.
2Ease of operation
If the shaft cover is exposed in the folded state with insufficient fixing, then the ease of operation is improved, but the reliability deteriorates due to potential warpage and deformation
Solution Approach 1:
The swing arm is pre-configured in a folded location where it automatically engages the mounting parts and applies tensile force to the shaft cover. This preliminary action ensures the shaft cover is pre-stabilized before any operational stresses are applied during the folded state.
Solution Approach 2:
The engaged mounting parts on the swing arm create a preliminary counteracting force against potential warpage and deformation of the shaft cover. This anti-action is established in advance through the folded position of the swing arm, preventing instability before it occurs.

AI summary
This application relates to the field of electronic device technologies, and provides a hook mechanism, a support apparatus, and an electronic device, which is used to resolve a problem that a shaft cover of an existing electronic device is not firmly fixed to a base, and the shaft cover may be subject to warpage and deformation, which affects overall aesthetic appearance. The hook mechanism includes a shaft cover, a base, and swing arms, and a plurality of first mounting parts are disposed in the shaft cover. The base is fixedly disposed in the shaft cover. The swing arms are disposed at two ends of the shaft cover along a first direction, and a second mounting part is disposed on the swing arm. The swing arm is rotatably connected to the base, so that the swing arm can rotate between an unfolded location and a folded location; and when the swing arms are in the unfolded location, the swing arms are located on two sides of the shaft cover along the first direction, and the first mounting part is separated from a corresponding second mounting part; or when the swing arms are in the folded location, the swing arms located on the two sides of the shaft cover along the first direction rotate to one side of the base away from the shaft cover and are disposed opposite to each other, and the first mounting part is mounted to the corresponding second mounting part.
