All-terrain vehicle seat backrest mounting structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing all-terrain vehicle seat installation structures suffer from instability and noise due to a large interstice between the backrest and frame, affecting driving comfort.
Innovation Solution
A seat installation structure featuring a first mounting part with an upper support frame and installation hole, and a second mounting part with a lower support frame and installation buckle, along with a conical limit head on the installation pin and a cushioning pad, to securely attach the seat backrest to the frame, preventing movement and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a separated structure with simple mounting is used for the seat backrest, then the device complexity is reduced and ease of manufacture is improved, but the stability of the backrest assembly structure deteriorates and large interstices are created between the backrest and frame
Solution Approach 1:
The mounting structure is divided into two separate mounting parts: a first mounting part at the upper end of the frame and a second mounting part at the lower end of the frame. This segmentation allows each part to be independently optimized for its specific mounting location, improving overall stability while maintaining structural simplicity
Solution Approach 2:
The installation pin is inserted into an installation hole to secure the upper support frame, creating a nested connection. The installation buckle at the lower end engages with the lower support frame, forming another nested connection. These nested structures eliminate interstices and enhance stability without significantly increasing complexity
2Ease of manufacture
If a simple separated structure is used for the seat backrest, then the ease of manufacture is improved, but noise is generated during vehicle travel due to instability and large interstices
Solution Approach 1:
The upper support frame and lower support frame are pre-configured with specific mounting features (installation hole and installation buckle respectively) that are designed to precisely engage with corresponding components. This preliminary configuration ensures proper alignment and eliminates gaps before final assembly, preventing noise generation during vehicle operation
Solution Approach 2:
The installation pin acts as an intermediary component that mediates the connection between the upper support frame and the seat backrest. The installation buckle serves as an intermediary at the lower connection point. These intermediary elements ensure stable engagement and eliminate interstices that would otherwise cause noise during vehicle travel
3Ease of operation
If the backrest is fixed with existing technology, then the basic mounting function is achieved, but relative vibration between the seat cushion and backrest occurs affecting driving comfort due to instability
Solution Approach 1:
The mounting system transitions from a single-point or simple connection to a dual-level mounting arrangement with upper and lower support frames positioned at different vertical levels. This dimensional distribution along the vertical axis creates a more stable triangular or rectangular mounting geometry, reducing relative vibration and improving driving comfort while maintaining ease of operation

AI summary
The invention provides a type of all-terrain vehicle seat installation structure; it includes the cab frame and the seat backrest arranged on the frame; the back mounting side of the seat backrest includes the first mounting part and the second mounting part arranged up and down respectively. The first mounting part includes the upper support frame located at the upper end of the frame; the installation hole is arranged on the upper support frame; the installation pin inserted into the installation hole is extended out of the seat backrest. The second mounting part includes the lower support frame located at the lower end of the frame; the lower end of the seat backrest is provided with the installation buckle mounted on the lower support frame. The top of the seat backrest is limited by the installation pin being inserted into the installation hole; the seat backrest is supported by the bottom installation buckle; the top of the seat backrest is limited by the inserting installation structure of the installation pin and the installation hole to avoid the seat backrest moving up and down on the frame, so the stability of the seat installation structure of the all-terrain vehicle is improved. The invention also provides a type of all-terrain vehicle provided with the seat installation structure of the all-terrain vehicle as described above.
