AI Technical Summary

Problems solved by technology

The manual release control mechanism manually controls the lock pin to leave the limit plate, that is, the lock pin is released from the limit position by turning the button on the inner panel, so that the inner handle can be pressed down to open the door, but its disadvantage is that the position of the button cannot be guaranteed. People with any hand shape can quickly open the door with one hand. For users with smaller hands, it is necessary to use one hand to pull the button and the other hand to press the handle to complete the door opening action, which is inconvenient to use
