Adjustable Handle Mechanism for Low-Speed Leaning Vehicle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operational feeling of the handle in front two-wheel leaning vehicles is compromised at low speeds, particularly when transitioning from a stationary state to extremely low speed, where the vehicle turns by handle rotation rather than leaning.
Innovation Solution
The handle position is adjusted in the top-bottom and front-rear directions through a mechanism that sets the handle height and offset amount relative to the steering shaft, enhancing the driver's ability to operate the vehicle by aligning the handle position with the driver's arm rotation range, thereby improving operational feeling across the speed range.

Engineering Contradiction Analysis
1Ease of operation
If the handle position is fixed in conventional vehicles, then the structure is simple, but the operational feeling is compromised at low speeds
Solution Approach 1:
The handle position is made adjustable rather than fixed, allowing the handle to be positioned at multiple heights and offset amounts to match the driver's arm rotation range. This dynamic adjustment capability improves operational feeling at low speeds while maintaining structural simplicity through a straightforward adjustment mechanism.
2Ease of operation
If the handle position is adjusted to match driver's arm rotation range, then operational feeling is enhanced, but the adjustment mechanism complexity increases
Solution Approach 1:
The handle position parameters (height and offset amount) are made variable to match different driver configurations and operating conditions. By adjusting these parameters, the handle can be optimized for low-speed operation where arm rotation is the primary control mechanism, enhancing operational feeling without requiring complex mechanical systems.

AI summary
A front two-wheel leaning vehicle, including a handle, a steering shaft, a linkage mechanism and a load transfer mechanism. The load transfer mechanism includes a left-foot-placing part and a right-foot-placing part located between the left front wheel and the rear wheel, for left and right feet of the driver to be respectively placed thereon. The load transfer mechanism transfers a load to the left and right portions of the linkage mechanism through the left-foot-placing part and the right-foot-placing part, or through the right-foot-placing part and the left-foot-placing part, respectively. The steering shaft includes a handle adjusting mechanism configured to adjust, with respect to the left-foot-placing part and the right-foot-placing part, at least one of a handle height, which is a distance from a midpoint between the left and right front wheels to the grip, or an offset amount of the handle with respect to a rotation axis of the steering shaft.
