After the driving device 6 drives the moving frame 51 to move to the conductive terminal 52 to be inserted into the insertion slot 42, the controller 13 controls the electric push rod 21 to start, so that the electric push rod 21 drives the moving plate 32 and the push rod to move, and the push rod no longer exerts an external force on the rotating buckle 71, and at this time, the rotating buckle 71 drives the fixing buckle 72 to rotate under the elastic force of the torsion spring 74, so that the fixing buckle 72 is inserted into the fixing slot 511.

As shown in fig. 1, 3 and 7, the driving device 6 includes a connecting rod 61, a rotating disc 62 and a rotating mechanism 63, the rotating disc 62 is rotatably connected to the inner side wall of the driving chamber 14, one end of the connecting rod 61 is hinged to the rotating disc 62, and the other end of the connecting rod 61 is hinged to the moving frame 51. In the process that the rotating mechanism 63 drives the rotating disc 62 to rotate, the rotating disc 62 drives the connecting rod 61 to move, and the connecting rod 61 moves to drive the moving frame 51 to move, so that the aim of conveniently driving the moving frame 51 to move is fulfilled.

As shown in fig. 1 and 7, the rotating mechanism 63 includes a threaded sleeve 631, a belt 632, a driving screw 633 and a pushing assembly 634, the threaded sleeve 631 is rotatably connected to an inner side wall of the driving cavity 14, the threaded sleeve 631 is sleeved on the driving screw 633, the driving screw 633 is a non-self-locking screw, and the driving screw 633 is in threaded connection with the threaded sleeve 631. The belt 632 is used to link the threaded sleeve 631 with the rotary disc 62.

As shown in fig. 1 and 7, the pushing assembly 634 includes a plurality of cushion plates 6341, a plurality of support rods 6342, a plurality of first springs 6343 and a plurality of second retaining rings 6344, wherein the plurality of support rods 6342 are disposed through the bottom plate 11, and the plurality of support rods 6342 are slidably connected to the bottom plate 11. The cushion plate 6341 is located the top of bottom plate 11, and the equal fixed connection in top of cushion plate 6341 and a plurality of bracing pieces 6342, and first spring 6343 is a plurality of, and a plurality of first springs 6343 one-to-one cover are located on a plurality of bracing pieces 6342, and the one end and the cushion plate 6341 fixed connection of first spring 6343, the other end of first spring 6343 with bottom plate 11 fixed connection. The number of the second limiting rings 6344 is multiple, the multiple second limiting rings 6344 are disposed corresponding to the multiple support rods 6342, and the second limiting rings 6344 are fixedly connected to one end of the support rod 6342 away from the cushion plate 6341.

As shown in fig. 1 and 4, the second pressure sensor 15 is fixedly mounted on the cushion plate 6341, a power input end of the second pressure sensor 15 is electrically connected to a power supply end of the controller 13, and a signal output end of the second pressure sensor 15 is electrically connected to one of signal input ends of the controller 13.

As shown in fig. 1, 4 and 7, when a user uses the seat, the second pressure sensor 15 can detect information of the user using the seat under the action of the self gravity of the user, and send the information to the controller 13, meanwhile, the cushion plate 6341 pushes the driving screw 633 to move under the action of the self gravity of the user, the driving screw 633 moves to drive the threaded sleeve 631 to rotate, the rotating disc 62 is driven by the belt 632 to rotate in the rotating process of the threaded sleeve 631, the rotating disc 62 rotates to drive the connecting rod 61 to move, the connecting rod 61 moves to drive the moving frame 51 and the conductive terminals 52 to move, so that the conductive terminals 52 are plugged in the plugging groove 42, and then the controller 13 controls the electric push rod 21 to start, so that the electric push rod 21 drives the push plate 311 to move, thereby achieving the purpose of enhancing the comfort level of the user during the use process.

The implementation principle of the full-automatic human back intelligent seat of laminating of this application embodiment does: in order to facilitate enhancing the comfort degree of the user in the process of using the seat, when the user uses the seat, the plurality of electric push rods 21 are respectively started, so that the plurality of electric push rods 21 push the plurality of movable plates 32 and the push plate 311 to move, so that the push plate 311 is attached to the back of the user, and meanwhile, for the users with different body heights and sitting postures, the use time of the electric push rods 21 is controlled, the plurality of push plates 311 can be attached to the back of the user, and the effect of enhancing the comfort degree of the user in the process of using the seat is achieved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
