DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0021] Embodiment 1 is given by Figures 1-4 The present invention relates to a massage mechanism for a massage chair backrest, including a backrest frame 1. An installation plate 2 is slidably arranged inside the backrest frame 1. A screw rod 3 is rotatably arranged on the backrest frame 1, and a driving motor 4 for driving the screw rod 3 to rotate is fixedly arranged. The screw rod 3 is in threaded cooperation with the threaded hole on the installation plate 2. Symmetrically fixed side plates 5 are arranged on both inner walls of the backrest frame 1. A wave groove 6 is formed on the side plate 5. Installation grooves 7 are symmetrically opened in the middle of the installation plate 2. Side grooves 8 are symmetrically opened on both sides of the installation plate 2. The side grooves 8 on the same side communicate with the installation grooves 7. A massage member is arranged inside the installation groove 7.

[0022] The massage member includes a sliding frame 9 slidably arranged inside the installation groove 7. A sliding block 10 is fixedly arranged at one end of the sliding frame 9 close to the side plate 5. The sliding block 10 is in contact with the wave groove 6. A return spring 11 is arranged between the end of the sliding frame 9 far from the side plate 5 and the inner wall of the installation groove 7. A massager is arranged inside the sliding frame 9.

[0023] With such a design, during use, the driving motor 4 drives the screw rod 3 to rotate. The screw rod 3 drives the installation plate 2 to slide up or down inside the backrest frame 1 by means of threads. During this period, under the action of the return spring 11, the sliding block 10 at the end of the sliding frame 9 can always be in contact with the wave groove 6 on the side plate 5. Since the wave groove 6 is a curved curve, during the sliding process of the sliding frame 9, the position of the sliding frame 9 inside the installation groove 7 will change along with the curved curve of the wave groove 6, so as to realize the movement of the massager along the horizontal direction of the sliding frame 9 and realize the massage process.

[0024] A through groove 12 is formed inside the sliding frame 9. The massager includes a plate body 13 slidably arranged inside the through groove 12. Massage rods 14 are uniformly fixedly arranged on the plate body 13. One end of the massage rod 14 passing through the rod hole on the sliding frame 9 is fixedly provided with a massage head 15. An expansion spring 16 is wound around the massage rod 14. The bottom end of the plate body 13 is fixedly arranged with the inner bottom wall of the through groove 12 through symmetrically arranged support springs 17. A vibration motor 18 is also fixedly arranged on the plate body 13.

[0025] With such a design, vibration can be carried out by the vibration motor 18. In cooperation with the setting of the support spring 17 and the telescopic spring 16, the plate body 13 can drive the massage rod 14 to move, and the massage rod 14 drives the massage head 15 to vibrate continuously. Through the massage head 15, massage operations can be continuously carried out, which is relatively convenient.

[0026] There are two sliding blocks 10, and a roller 19 is rotatably arranged between the two sliding blocks 10; with such a design, the wear between the sliding block 10 and the side plate 5 can be reduced through the roller 19, playing a protective role.

[0027] A positioning column 20 is also fixedly arranged on the sliding frame 9, and the return spring 11 is wound around the outside of the positioning column 20; with such a design, it is convenient to install the return spring 11.

[0028] Integrated strip plates 21 are fixedly connected to both sides of the backrest frame 1. The two strip plates 21 are respectively in sliding cooperation with the two ends of the sliding frame 9, and the side plate 5 is in sliding cooperation with the side groove 8; with such a design, it is convenient to support the sliding frame 9 through the strip plates 21 and improve the support strength.
