Vehicle Glove Box Push Rod Guide Rod Rattle Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glove box locking mechanisms in vehicles often require users to pull and rotate a knob or press a button, which can lead to shaking or rattling during vehicle travel, compromising operational sensitivity and safety.
Innovation Solution
A push rod housing and guide rod system is integrated into the glove box door, allowing the push rod to slide smoothly without shaking, guided by protruding portions and grooves or a guide rod, enhancing operational sensitivity and preventing rattling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pull type locking device or push type locking device is used without guidance mechanism, then the locking function is achieved, but the knob shakes or rattles during operation and vehicle travel
Solution Approach 1:
A guide rod is introduced as an intermediary component between the push rod and the external environment. The guide rod receives the pushing force from the push rod and transmits it to the locking mechanism through its outer surface, while its rigid structure prevents shaking and rattling of the knob during operation and vehicle travel.
Solution Approach 2:
The guide rod extends along the outer surface of the push rod housing in a direction perpendicular to the sliding direction of the push rod. This dimensional arrangement allows the guide rod to provide lateral support and constraint, preventing the push rod from shaking during sliding while maintaining the locking function.
2Device complexity
If a simple push rod structure is used, then the device complexity is low, but the push rod shakes during sliding compromising operational sensitivity
Solution Approach 1:
The guide rod serves as a mediator that provides guidance and support to the push rod during sliding. By introducing this additional component, the system achieves improved operational sensitivity and reduced shaking without requiring complex manufacturing precision in the push rod itself, as the guide rod absorbs the guidance function.
3Device complexity
If the push rod slides without guidance, then the device is simple, but rattling occurs due to vehicle vibrations reducing safety
Solution Approach 1:
The guide rod acts as a protective intermediary that shields the push rod from the harmful effects of vehicle vibrations. The guide rod's rigid structure and alignment along the push rod housing prevent vibration-induced rattling, thereby improving safety without significantly increasing device complexity.

AI summary
A glove box for a vehicle according to the present invention includes: a push rod housing which is fixed to a glove box door; a push rod which is slidably disposed in the push rod housing in order to lock or unlock the glove box door; and a guide rod which is coupled to the push rod, and moved along an outer surface of the push rod housing when the push rod slides, such that when a user presses the knob, the knob is operated without rattling.
