AI Technical Summary
Existing folding handrails have shortcomings in stability, ease of operation, adjustability, structural strength, and comfort. Traditional hinge limit structures are simple, prone to wobbling, inconvenient to operate, and lack elastic cushioning, affecting the user experience and lifespan.
The armrest is folded and unfolded by sliding the hinge rod in the slot. The compression and extension of the spring provides locking force to assist unfolding. The locking rod adjusts the preload of the spring to suit different users' force preferences, and elastic pads are set in the armrest to improve comfort.
It achieves reliable folding and unfolding of the handrail, improves locking stability and ease of operation, enhances structural strength and user comfort, and adapts to the operating needs of different users.
