Slidable Keyboard Mechanism for Portable Device Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face challenges in heat dissipation due to the compact arrangement of heat-generated components, which hinders their thinning and efficiency, as the space for heat dissipation components is limited and crowded.
Innovation Solution
A portable electronic apparatus with a slidable structure and interlocking mechanism that allows the keyboard component to move away from the base when the display component is rotated, creating a heat dissipation channel by sliding the slidable structure relative to the base, enabling better airflow for heat exchange.

If electronic components are assembled more compactly into a limited space to achieve thinning, then the portable electronic apparatus becomes thinner and lighter, but heat dissipation space is reduced and heat accumulation increases
Solution Approach 1:
The keyboard component is designed to be movable relative to the base through a slidable structure. When the display component is rotated away from the base (open state), the slidable structure slides to push the keyboard component away from the base, dynamically creating a heat dissipation channel. This dynamic adjustment allows the device to maintain thin profile during normal use while providing enhanced heat dissipation when needed during intensive operations.
Solution Approach 2:
The heat dissipation solution transitions from a two-dimensional planar arrangement to a three-dimensional spatial configuration. By moving the keyboard component away from the base in the vertical dimension, a heat dissipation channel is created that utilizes the third dimension (depth/thickness) to improve heat exchange with the environment, thereby addressing heat accumulation without increasing the device's overall footprint.

If heat dissipation components are added to improve heat exchange, then heat dissipation efficiency improves, but the device complexity and space requirements increase
Solution Approach 1:
The slidable structure is designed to be actuated by the display component's rotation itself. The interlocking structure between the display component and slidable structure automatically pushes the keyboard component away from the base when the display is opened, without requiring separate actuators, motors, or control systems. This self-actuating mechanism improves heat dissipation efficiency while minimizing the addition of complex components.

AI summary
Portable electronic apparatus includes a display component, a base, a keyboard component, and a slidable structure. The display component includes an interlocking structure. The base includes a pivotally-connected portion, pivotally-connected to the display component. The keyboard component disposed on the base can move toward or away from the base. The slidable structure disposed between the base and the keyboard component can slide relative to the base. The slidable structure includes a protruding portion, protruding along a side of the slidable structure away from the base. While the display component is rotated away from the base, the interlocking structure of the display component is actuated by the rotated display component, and drive the slidable structure to slide away from the pivotally-connected portion, moved relative to the base. Subsequently, the first protruding portion of the slidable structure pushes the keyboard component moving away from the base.
