The fixed plate 1 includes an air cavity 701, the upper side of the air cavity 701 is fixedly connected with the lower side of the fixed plate 1, the inside of the air cavity 701 is hollow, and the inner wall of the air cavity 701 is slidably connected with a sliding plate 702, one part of the sliding plate 702 The side is fixedly connected with a second spring 703, the other end of the second spring 703 is fixedly connected with the inner wall of the air chamber 701, the other side of the sliding plate 702 is fixedly connected with a pull cord 704, and the thickness control mechanism 7 also includes a bracket 705, a bracket 705 The upper end of the upper end is fixedly connected with the outer wall of the backboard 4, the other end of the stay rope 704 runs through the air cavity 701 and extends to the outside of the air cavity 701, and is fixed on the outer wall of the backboard 4 via the bracket 705. The thickness control mechanism 7 also includes a connecting pipe 706 One end of the connecting pipe 706 communicates with the interior of the air cavity 701, the other end of the connecting pipe 706 passes through the counterweight 602 and extends to the other side of the counterweight 602 and communicates with the interior of the fixed shell 604, and the connecting pipe 706 communicates with the interior of the fixed shell 604. The internal communication side of the air chamber 701 is located on the side of the sliding plate 702 away from the pull cord 704 , the second spring 703 is in a stretched state, and the outer wall of the connecting pipe 706 is fixedly connected with the inner wall of the air chamber 701 .

The vibrating mechanism 8 includes a first magnet 801. The first magnet 801 is arranged inside the backboard 4. The vibrating mechanism 8 also includes a fixed column 802. One end of the fixed column 802 is fixedly connected to the inner wall of the fixed shell 604, and the outer wall of the fixed column 802 slides. A second magnet 803 is connected, and a third spring 804 is fixedly connected to one side of the second magnet 803. The side of the outer wall of the first magnet 801 and the outer wall of the second magnet 803 that are close to each other are opposite magnetic poles, and the third spring 804 is in a contracted state. , the other end of the third spring 804 is fixedly connected with the inner wall of the fixed shell 604, the outer wall of the second magnet 803 is hinged with a vibrating plate 805 through a torsion spring, the other side of the vibrating plate 805 is in contact with the outer wall of the rubber bag 605, and the vibrating mechanism 8 It also includes a stopper 806 , the outer surface of the stopper 806 is fixedly connected with the inner wall of the fixed shell 604 , and the outer surface of the stopper 806 is in contact with the outer wall of the vibrating plate 805 .

During use, under the normal sitting posture, the fixed shell 604 and the gas inside the rubber bag 605 can reach the effect of the waist pad. No longer jam each other, and then the backrest board 4 is laid down backward, so that the backrest board 4 and the fixed board 1 form an acute angle that is convenient for rest, and when the armrest 5 is re-carded on the first fixed leg 2, it is convenient for the staff to lie down and have a rest ;

When the backboard 4 is down, because the backboard 4 is tilted, the supporting force of the counterweight 602 inside the chute becomes stronger and stronger, and the first spring 601 will rebound to pull the counterweight 602 upwards. , so that the counterweight 602 drives the connecting cloth 603 and the fixed shell 604 to move upwards, making them move to the position of the neck, so as to achieve the effect of being used as a pillow;

In the process of backboard 4 toppling over, due to the flat angle between the backboard 4 and the fixed plate 1, the pulling effect of the support 705 on the stay cord 704 will be reduced, and after the stay cord 704 is relaxed, due to the elastic force of the second spring 703 Pull the sliding plate 702 so that the sliding plate 702 is close to the connection between the connecting pipe 706 and the inside of the air cavity 701, and the gas inside the air cavity 701 is squeezed into the inside of the fixed shell 604 through the connecting tube 706, so that the inside of the fixed shell 604 is closed due to the increase of gas. Inflate the rubber bladder 605 to increase the thickness of the rubber bladder 605 and the fixed shell 604, so as to achieve the effect of increasing the thickness to facilitate a more comfortable pillow;

After the rest, the armrest 5 can be lifted away from the first fixed leg 2, and then the armrest 5 is pulled to make the backboard 4 return to the working angle. It will cause the first spring 601 to fall and pull the first spring 601 to deform, so that the counterweight 602 will drive the connecting cloth 603 and the fixed shell 604 to drop to the position of the waist pad, so as to achieve the function of the waist pad, thereby achieving the purpose of being convenient for storage and use;

Now, because the lower end of the bracket 705 protrudes backward, the pull cord 704 will be pulled to displace the sliding plate 702, so that the inside of the air chamber 701 will return part of the gas inside the fixed shell 604 to the inside of the air chamber 701 through the connecting pipe 706, thereby achieving Reduce the thickness of the fixed shell 604 and the rubber bag 605, which is convenient for the waist;

After the fixed shell 604 falls, the second magnet 803 will move to the first magnet 801. Since the first magnet 801 and the second magnet 803 will attract each other, the second magnet 803 will move closer to the first magnet 801 in an instant, so that While the third spring 804 contracts, the vibrating plate 805 is blocked by the stopper 806, causing the end of the vibrating plate 805 away from the fixed column 802 to lift and hit the surface of the rubber bag 605, which can remove the hair dander adhered to the surface of the rubber bag 605, Prevents sticking to clothing when used as a backrest.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, any person familiar with the technical field within the technical scope disclosed in the present invention, according to the technical solution of the present invention Any equivalent replacement or change of the inventive concepts thereof shall fall within the protection scope of the present invention.
