Electric Scooter Clutch Wheel Locking for Stable Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clutch mechanisms in electric scooters are unstable and prone to accidental switching between transmission connection and separation, leading to user obstacles and potential damage.
Innovation Solution
A clutch type driving wheel with a controlled clutch structure and clutch state locking mechanism, featuring a cylindrical clutch part with convex teeth and grooves for stable engagement and disengagement, and an annular damping ring for locking, ensuring stable transmission connection or separation states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a clutch device is arranged between the wheel core and the belt pulley to enable connection or separation, then the traveling resistance is reduced when the motor is shut down, but the stability of the connection and separation states cannot be ensured, causing accidental switching
Solution Approach 1:
The spring pre-compresses the first elastic element before operation, storing potential energy that ensures reliable engagement. When the clutch needs to engage, the pre-compressed spring automatically pushes the elastic element into the groove, ensuring positive engagement without requiring additional actuation force.
Solution Approach 2:
The first elastic element acts as a cushioning mechanism between the clutch plate and the driving structure. It absorbs shock and vibration during engagement and separation, preventing accidental disengagement due to external forces while maintaining stable connection states during normal operation.
2Device complexity
If the clutch device uses simple engagement structures, then the device complexity is reduced, but the engagement force distribution is uneven, affecting stability
Solution Approach 1:
The clutch plate is divided into multiple segments with individual grooves, allowing the engagement force to be distributed across multiple contact points. This segmentation ensures uniform force distribution while keeping each individual groove structure simple and easy to manufacture.

AI summary
Provided is a clutch type driving wheel of an electric scooter. The clutch type driving wheel of the electric scooter includes a wheel body and a power shaft penetrating through the center of the wheel body, wherein a motor power input structure is arranged at one end of the power shaft, a central supporting shaft penetrates through the power shaft, a controlled clutch structure enabling the wheel body to be circumferentially positioned relative to the power shaft or enabling the wheel body to circumferentially rotate relative to the power shaft when the controlled clutch structure acts is arranged between the power shaft and the wheel body, and a clutch state locking structure is arranged on the controlled clutch structure. According to the clutch type driving wheel of the electric scooter, the clutch state locking structure is arranged between the power shaft and the wheel body. It is ensured that when the power shaft and the wheel body are in a transmission connection state or a mutual separation state, the state stability can be maintained.
