Clutch System for Electric Vehicle Mover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric moving devices for vehicles are inefficient and inconvenient due to their simple structure and limited operation modes, affecting usability and work efficiency, especially when encountering obstacles or power failures.
Innovation Solution
An electric moving device with a base frame, steering handle mechanism, and a clutch system that allows for both electric drive and manual operation, featuring a clutching-in and clutching-out state, a sun gear, planet gear, and transmission gear ring system for deceleration and multifunctionality, along with a locking mechanism for easy direction control and improved balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple structure with single function is used, then the device complexity is reduced, but the adaptability and operation modes are limited
Solution Approach 1:
The clutch system is designed to provide multiple operation modes (electric drive mode and manual push mode) through a single integrated mechanism. The clutch gear can engage with either the driver gear or the transmission gear ring, allowing the device to switch between electric drive and manual push functions, thereby achieving multi-functionality without requiring separate independent systems for each mode.
2Volume of moving object
If the clutch system includes deceleration function, then the device integrates multiple functions reducing overall size, but the device complexity increases
Solution Approach 1:
The clutch system merges the clutching function and deceleration function into a single integrated mechanism. The same clutch gear that engages/disengages the driver also provides deceleration by meshing with the transmission gear ring, which has a different number of teeth than the driver gear. This combination of functions in one mechanism reduces the overall device size while managing the complexity through unified design.
3Ease of operation
If the clutching handle has large axial stroke for engagement, then the clutch system is easier to operate, but the device size increases
Solution Approach 1:
The clutching mechanism converts the axial movement of the clutching handle into rotational movement of the clutch gear through a rack-and-pinion mechanism. The clutching shaft has teeth that engage with the clutch gear, transforming linear axial displacement into rotational displacement. This dimensional transformation allows for adequate engagement stroke while maintaining a compact device size.

AI summary
An electric moving device for vehicles, relating to the trailer area, having a base frame, a travelling mechanism, a steering handle mechanism, a driving mechanism and an electric control assembly. The base frame has a support frame and a connecting frame, and the connecting frame is disposed over the support frame. The travelling mechanism has roller wheels on the support frame, and the driving mechanism has a driver and a clutch system. The driver and clutch system are located on two sides of the support frame separately. The clutch system has an input end connected to the driver in a transmission way and an output end connected to the roller wheels in a transmission way. The steering handle mechanism is rotationally fixed to the base frame so the steering handle mechanism could deflect to the two sides of the travelling direction of the moving device for vehicles.
