ATV Air Intake Pipe Twist-Lock Structure for Vibration Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection between the filter sleeve and the intake pipe of an all-terrain vehicle is unstable due to vibration fatigue, leading to loosening and noise, and current solutions using steel belts are inadequate.
Innovation Solution
A twist-lock buckle structure is implemented with positioning grooves and blocks on the pipe body and filter sleeve, allowing for a locked or unlocked state through rotational adjustment, featuring L-shaped guides, snap-fit grooves, and cambered surfaces for stable connection and easy assembly/disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a steel belt type hoop is used to fix the filter sleeve to the intake pipe, then the connection is initially stable, but the hoop becomes loosened over time due to vibration fatigue
Solution Approach 1:
The connection structure is segmented into multiple positioning blocks distributed circumferentially on the filter sleeve and corresponding positioning grooves on the intake pipe. This segmentation distributes the vibration stress across multiple points rather than concentrating it on a single hoop, preventing vibration fatigue and loosening while maintaining connection stability over extended service life.
2Reliability
If a steel belt type hoop is used to fix the filter sleeve, then the connection is secure, but disassembly and assembly become difficult
Solution Approach 1:
The connection structure transitions from a static hoop to dynamic positioning blocks with movable positioning portions. The positioning portions can be manually moved along the guiding surfaces of the positioning grooves to transition between locked and unlocked states, enabling easy disassembly and assembly while maintaining secure connection during operation.
3Reliability
If the filter sleeve is tightly fixed to prevent loosening, then connection stability improves, but the structure becomes more complex
Solution Approach 1:
The positioning blocks serve multiple functions: they provide connection stability through the locked positioning state, enable easy disassembly through the unlocked state, guide alignment during assembly via guiding surfaces, and distribute vibration stress across multiple circumferential points. This multi-functionality achieves reliable connection without increasing structural complexity.

AI summary
Provided is an intake pipe structure of an all-terrain vehicle, which belongs to the technical field of parts of all-terrain vehicles. The present disclosure solves the problem of poor stability of a connection between a filter sleeve and a pipe body of an intake pipe in the prior art. The intake pipe structure of the all-terrain vehicle includes a pipe body and a filter sleeve arranged on the pipe body, where a plurality of positioning grooves are provided on the pipe body, a plurality of positioning blocks are arranged on the filter sleeve, the plurality of positioning grooves are distributed on an outer wall of an intake end of the pipe body in a circumferential direction, the plurality of positioning blocks are distributed on an inner wall of the filter sleeve in a circumferential direction, the positioning blocks can be embedded in or separated from the positioning grooves, and by rotationally adjusting relative positions of the positioning blocks and the positioning grooves, a locked state or an unlocked state can be formed between them. The present disclosure has the advantage that stability of a connection between the filter sleeve and the pipe body of the intake pipe is improved while disassembly and assembly are facilitated.
