[0028] Reference Figure 1 As shown, this utility model provides a technical solution: an electric headrest assembly for a massage chair, including a headrest body 1 and a lower mounting base 2. Two telescopic rod bodies 5 are fixedly installed on the upper surface of the lower mounting base 2. An upper mounting base 4 is fixedly connected to the upper ends of the two telescopic rod bodies 5. The headrest body 1 is installed above the upper mounting base 4. An electric telescopic rod 3 is fixedly installed between the upper mounting base 4 and the lower mounting base 2. A switching structure 6 is provided on the surface of the headrest body 1, and an adjustment structure 7 is provided between the headrest body 1 and the upper mounting base 4.

[0029] The specific settings and functions of its switching structure 6 and adjustment structure 7 will be explained in detail below.

[0030] Reference Figure 1-3As shown in this embodiment: the switching structure 6 includes two mounting plates 604 fixedly installed on the back side of the headrest body 1. Each mounting plate 604 has a pull hole 609 on its surface. A fabric strip 603 is slidably connected to the inner side of the pull hole 609. A sponge plate 601 is fixedly connected between the two fabric strips 603. Several silicone heads 602 are glued to one side of the sponge plate 601. The side with the silicone heads 602 faces the user, providing massage and different tactile experiences. If the sponge plate 601 is completely retracted, the original surface of the headrest body 1 directly contacts the user, achieving the switching of the pillow surface. A limiting rod 605 is fixedly connected to the surface of the mounting plate 604. A rectangular strip 611 is slidably connected to the side wall of the limiting rod 605. Several conical rods 608 are evenly fixedly connected to the surface of the rectangular strip 611. The tips of the conical rods 608 slide through the mounting plate 604. The conical rods 608 serve to fix the position of the fabric strip 603. The mounting plate 604 has several evenly spaced circular grooves 610 on its inner side of the extraction hole 609. The size of the circular grooves 610 matches the size of the tapered rod 608. The tip of the tapered rod 608 slides through the mounting plate 604 and inserts into the circular groove 610. A stop block 606 is fixedly connected to the other end of the limiting rod 605. A spring 607 is fitted onto the surface of the limiting rod 605, and both ends of the spring 607 are fixedly connected to the stop block 606 and the rectangular bar 611, respectively. Under the action of the spring 607, the tip of the tapered rod 608 slides through the mounting plate 604 and inserts into the circular groove 610.

[0031] Reference Figure 1-2 and Figure 4 As shown, specifically, the adjustment structure 7 includes two positioning plates 72 fixedly connected to the upper surface of the upper mounting base 4. A pivot pin 74 is rotatably connected inside each of the two positioning plates 72, and a mounting strip 71 is fixedly connected between the two pivot pins 74. The upper side of the mounting strip 71 is fixedly connected to the headrest body 1. The adjustment structure 7 is used to adjust the angle of the headrest body 1. A connecting block 75 is fixedly connected to the side wall of the pivot pin 74, and a bolt 76 is threaded into the connecting block 75. Rotating the mounting strip 71 causes the pivot pin 74 to rotate within the positioning plate 72, thereby adjusting the tilt angle of the headrest body 1. The surface of the positioning plate 72 has a circumferential array of several insertion holes 73, the size of which matches the size of the bolt 76. Rotating the bolt 76 causes one end of the bolt 76 to insert into the corresponding insertion hole 73 on the surface of the positioning plate 72, thereby fixing the position of the pivot pin 74.

[0032] Working principle: If the user wants to switch the pillow surface, they need to operate the switching structure 6. First, select the usable surface of the sponge board 601 according to the user's needs. Pass the fabric strip 603 through the drawer 609. When the fabric strip 603 is pulled, it slides within the drawer 609, moving the sponge board 601. Pull the sponge board 601 to the appropriate position, at which point the side with the silicone head 602 faces the user, providing massage and different tactile experiences. If the sponge board 601 is completely retracted, the original surface of the headrest body 1 directly contacts the user, realizing the switching of the pillow surface. In the middle, the rectangular bar 611 slides on the limiting rod 605, and the cone rod 608 on it moves with the rectangular bar 611. When the cone rod 608 moves to align with the circular groove 610 inside the hole 609 on the mounting plate 604, under the action of the spring 607, the tip of the cone rod 608 will slide through the mounting plate 604 and insert into the circular groove 610, which will fix the position of the fabric strip 603, prevent the sponge board 601 from sliding at will, and ensure the stability of the pillow surface after switching. By setting the switching structure 6, the flexible switching of the pillow surface of the headrest body 1 is facilitated, which meets the usage needs of different users.

[0033] The adjustment structure 7 is used to adjust the angle of the headrest body 1. By rotating the mounting strip 71, the mounting strip 71 drives the pivot pin 74 to rotate within the positioning plate 72, thereby adjusting the tilt angle of the headrest body 1. After adjusting to a suitable angle, the bolt 76 is rotated so that one end of the bolt 76 is inserted into the corresponding insertion hole 73 on the surface of the positioning plate 72, thereby fixing the position of the pivot pin 74 and locking the angle of the headrest body 1. This allows the user to enjoy massage services at a more comfortable angle. By setting the adjustment structure 7, the flexible adjustment of the use angle of the headrest body 1 is facilitated, further improving the performance of the headrest body 1.
