AI Technical Summary
The existing seat tray adjustment function is selected through multiple holes or fixed with bolts, which is troublesome to adjust and easy to loosen.
Using electromagnets and iron sheets as locking components, the electromagnets are energized and de-energized by an electronic switch to achieve multi-level adjustment. Combined with the design of rotary joints and sliding grooves, the seat tray can be adjusted in multiple directions and linearly.
It achieves high adjustment precision and convenient adjustment. Multi-directional rotation and linear adjustment do not require unlocking each lock individually, improving the convenience and stability of adjustment.
