Steering Wheel Vibration Device Mounting Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering wheel vibration devices fail to effectively transmit vibrations from the vibration motor to the ring section, resulting in inadequate alerting of the driver when the vehicle is about to leave the lane.
Innovation Solution
The steering wheel design includes a vibration device with a vibration motor and a mounting bracket that presses the motor body against a vibration receiving section on the core, which is connected to the ring section, allowing for direct transmission of vibrations. An elastically deformable spacer is used to absorb assembly errors and enhance vibration transmission, ensuring the ring section vibrates perceptibly even with small motor vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the vibration motor is mounted separately from the core with only mounting sections connected, then the structure is easier to assemble, but the vibration transmission effectiveness deteriorates
Solution Approach 1:
The patent merges the vibration motor mounting structure with the core by providing mounting sections that extend from the holding section and are secured to the core. This integration ensures that the motor body directly presses the core during vibration, improving vibration transmission effectiveness while maintaining assembly ease through the unified structure.
Solution Approach 2:
The mounting bracket acts as an intermediary component that connects the vibration motor to the core. It includes a holding section that holds the motor and mounting sections that secure to the core, serving as a mediator that ensures effective vibration transmission while facilitating assembly.
2Reliability
If the motor body directly presses the core during vibration, then vibration transmission effectiveness improves, but the device complexity increases
Solution Approach 1:
The mounting bracket combines multiple functions into a single component: it holds the vibration motor, provides mounting sections that secure to the core, and enables direct pressure transmission from the motor body to the core during vibration. This integration improves vibration transmission without proportionally increasing complexity.
Solution Approach 2:
The mounting bracket serves multiple functions simultaneously: it acts as a holding structure for the motor, a mounting structure that secures to the core, and a transmission medium for vibration forces. This multi-functionality achieves effective vibration transmission while minimizing the number of separate components.

Function Achieved in This Case
This configuration ensures strong and perceivable vibrations are transmitted to the ring section, effectively alerting the driver of lane departure, with improved vibration transmission and assembly reliability.
Implementation Method 1
a rotational axis protruding out of the motor body and an eccentric weight attached to the rotational axis
Implementation Method 2
The pressing section presses a distant region of an outer circumference of the motor body, which faces away from the vibration receiving section, toward the vibration receiving section
Implementation Method 3
an elastically deformable spacer is used to absorb assembly errors and enhance vibration transmission

AI summary
A steering wheel provided with a vibration device. The vibration device includes a vibration motor with an eccentric weight attached to a rotational axis protruding out of a motor body and a mounting bracket which mounts the motor on a mounting section located at a region continuous with a ring section on a steering wheel core. The mounting section includes a vibration receiving section and a mounting base. The mounting bracket includes a pressing section which presses the motor body against the vibration receiving section and a mounting tongue which is secured to the mounting base. The mounting bracket is mounted on the mounting base with the motor body disposed on the pressing section in such a manner as to press a region of the motor body facing the vibration receiving section against the vibration receiving section and transmit a vibration of the motor body to the vibration receiving section.
