Vehicle Trunk Awning Hook-Stopper Structure Against Hardboard Sag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing awnings for vehicle trunks suffer from poor perceived quality due to the counterclockwise sinking of the rear end or rotation of the awning body relative to the horizontal plane caused by the gravity of the hardboard at the rear end.
Innovation Solution
An awning system with a connection system that includes a hardboard, first hooks fixed to the hardboard, second hooks connected to the tailgate, and stoppers made of rubber material to apply supporting stress, preventing the hardboard from sinking by shifting its center of gravity towards the tailgate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a hardboard is installed at the rear end of the awning body to provide structural support, then the strength and stability of the awning are improved, but the hardboard sinks counterclockwise due to its own gravity, causing the awning body to rotate relative to the horizontal plane and deteriorating the perceived quality of the vehicle
Solution Approach 1:
The patent introduces a stopper component that acts as a counterbalancing mechanism. The stopper includes a supporting portion that contacts the tailgate and a hooking portion that engages with the first hook. This creating a counterbalancing force system that offsets the gravitational effect on the hardboard, preventing the counterclockwise sinking and maintaining the awning body's horizontal alignment while preserving the structural support function of the hardboard
Solution Approach 2:
The stopper serves as an intermediary component between the hardboard (via the first hook) and the tailgate. It mediates the gravitational force acting on the hardboard by transferring the load to the tailgate through its supporting portion, while its hooking portion maintains the connection to the first hook. This intermediary mechanism prevents direct sinking of the hardboard while maintaining structural support
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The awning system effectively prevents the hardboard from sinking, thereby improving the perceived quality of the vehicle by maintaining the awning body in a horizontal state, enhancing its appearance and functionality.
Implementation Method 1
one or more stoppers, disposed on a tail end of the first hook, made of rubber material, and having a head protruding backwards from a surface of the first hook, the head abutting against a trim of the tailgate to apply a supporting stress to the tail end of the first hook

AI summary
The present application relates to an awning (10) for a trunk of a vehicle and a vehicle. The awning (10) includes: an awning body (100); and a connection system, configured to connect the awning body (100) to a tailgate of the trunk and including: a hardboard (210), disposed within a tail end of the awning body (100); one or more first hooks (220), a front end thereof fixed to a front end of the hardboard (210) and extending downward from the front end of the hardboard (210) and toward the tailgate; one or more second hooks (230), a front end thereof rotatably connected to the first hook (220) and a tail end thereof connected to the tailgate; and one or more stoppers (240), disposed on a tail end of the first hook (220), made of rubber material, and having a head (2410) protruding backwards from a surface of the first hook (220), the head (2410) abutting against a trim of the tailgate to apply a supporting stress (F3) to the tail end of the first hook (220), the front end of the first hook (220) supporting the front end of the hardboard (210) based on the supporting stress (F3), thereby preventing the hardboard (210) from sinking due to a gravity thereof.
