As shown in fig. 6 to 9, the handle includes a backrest control handle 1 and a cushion control handle 2 respectively installed at the rear portions of both sides of the cushion, and is generally located under the cushion armrests, so as to conform to the operation habit of the human body and improve the use feeling of the user. Preferably, the backrest control handle 1 is mounted on the left side of the seat cushion, and the seat cushion control handle 2 is mounted on the right side of the seat cushion. In other embodiments, the backrest control handle 1 and the cushion control handle 2 may be mounted on the same side of the cushion, or the backrest control handle 1 may be mounted on the right side of the cushion, and the cushion control handle 2 may be mounted on the left side of the cushion, and may be adjusted according to practical situations.

The backrest control handle 1 is in transmission connection with the backrest dumping control device through a first pull wire and controls the backrest to be dumped and to recover the vertical state. The cushion control handle 2 is connected with the cushion lifting control device in a transmission way through a second stay wire and controls the ascending and descending of the chair cushion. Both sides of the cushion are provided with grooves, two handles are respectively arranged in the grooves, the rear ends of the handles are matched with the cushion to form a revolute pair, and a spring reset structure is arranged on the revolute pair.

When the cushion control handle 2 is pulled, the second pull wire pulls the connecting lever 7 to rotate downwards so that the bulge presses the gas rod top switch downwards, and then the cushion is pressed downwards artificially, so that the descent of the cushion can be realized. After the cushion control handle 2 is lowered to a proper height, the cushion control handle 2 can be loosened, and at the moment, the bulge of the connecting lever 7 does not press the top switch of the air rod any more, so that the air rod can be locked, and the height is fixed. The operation of the cushion up is similar to this.

The backrest can be inclined and righted through a simple structure, the rising and the falling of the cushion can be realized, the production cost is greatly reduced, and the benefit is improved. Meanwhile, the operation of the client is simple, the user can adjust the angle and the height to proper angles only by pulling the handle, and the use feeling and the satisfaction degree of the user are greatly improved.

Example 2

As shown in fig. 6 and 7, a seat according to the present utility model, which adopts the drive-by-wire tray of embodiment 1, further includes the seat cushion and the backrest. When the backrest control handle 1 is pulled, the backrest locking buckle 6 is pulled by the first pull wire, so that the backrest locking buckle 6 is separated from the backrest locking gear 5, at the moment, the backrest is tilted to a proper angle by artificial leaning back, the backrest control handle 1 is loosened again, the backrest locking buckle 6 is automatically close to the backrest locking gear 5 and is clamped into one buckle position under the elastic drive of the backrest locking buckle reset torsion spring 12, the angle is fixed, and the leaning back and locking of the backrest are realized. When the cushion control handle 2 is pulled, the second pull wire pulls the connecting lever 7 to rotate downwards so that the bulge presses the gas rod top switch downwards, and then the cushion is pressed downwards artificially, so that the descent of the cushion can be realized. After the cushion control handle 2 is lowered to a proper height, the cushion control handle 2 can be loosened, and at the moment, the bulge of the connecting lever 7 does not press the top switch of the air rod any more, so that the air rod can be locked, and the height is fixed. Simple structure, greatly reduced manufacturing cost, and improved benefit. Meanwhile, the operation of the client is simple, the user can adjust the angle and the height to proper angles only by pulling the handle, and the use feeling and the satisfaction degree of the user are greatly improved.
