Abstract: A power supply mechanism for a long-stroke seat has a wire harness accommodation box having at least one accommodation space and at least one opening; a drag chain bent and accommodated in the accommodation space, where a first end of the drag chain is relatively fixed to the wire harness accommodation box, and a second end of the drag chain passes through the opening and is slidably disposed in a slideway of a lower slide rail of the seat; a wire harness threaded in the drag chain, where a first end of the wire harness passes through a first end of a wire harness channel and the opening to be connected to a power supply, and a second end of the drag chain passes through a second end of the wire harness channel to be connected to an upper slide rail of the seat.

Abstract: A quick fitting and protection mechanism for a wire harness in a slide rail has a drag chain for the wire harness to be threaded through; a drag chain towing support connected to an upper slide rail and slidable in a slideway of a lower slide rail with the upper slide rail, where the drag chain towing support has a drag chain port, a wire harness outlet, and a first channel affording communication between the drag chain port and the wire harness outlet, where one end of the drag chain is connected to the drag chain port; a wire harness guide support having a wire harness entry, a wire harness exit, and a second channel affording communication between the wire harness entry and the wire harness exit, where the wire harness entry is in rotatable communication with the wire harness exit.

Abstract: A control method for an air conditioner is provided. The air conditioner has a retractable top air output mechanism provided at a top thereof. The control method includes: controlling, in response to a specified wind shower instruction in a cooling mode, the top air output mechanism to stretch towards an outside of the air conditioner to open an air outlet of the top air output mechanism; adjusting, based on the specified wind shower instruction, an air-out included angle of the top air output mechanism to be within a first angle range; and adjusting, based on the specified wind shower instruction, a supply air speed of the top air output mechanism to be within a first air speed range.
