[0045] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] Embodiment 1:

[0048] Please refer to Figure 1 and Figure 2 The figure is a schematic structural diagram of the first embodiment of a headrest bracket of the present application, comprising a main bracket 100 and a wing bracket 200 hinged on both sides of the main bracket 100; two insertion rods 300 are rotatably fixed to the bottom of the main bracket 100; the bottom surface of the main bracket 100 is provided with two symmetrically designed arc grooves 110, and the two arc grooves 110 are co-centered; the top ends of the two insertion rods 300 are slidably stuck in the two arc grooves 110 respectively; in the present embodiment, the mutual rotation between the main bracket 100 and the wing bracket 200 needs to overcome a certain resistance, and the specific amount of resistance that needs to be overcome can be set according to actual needs, and preferably the rotational friction coefficient between the main bracket 100 and the wing bracket 200 is above 0.5. Before the headrest bracket is installed, the installation position can be adjusted by rotating the angle between the wing bracket 200 and the main bracket 100, which makes the installation of the headrest convenient; after the headrest bracket is installed in the headrest, the side of the headrest can be bent as a whole so that the wing bracket 200 drives the edge of the headrest to rotate, so as to adjust the inclination angle of the edge of the headrest to improve the comfort of the headrest; when the headrest is pressed sideways, for example, when the passenger sleeps with his head tilted, the wing bracket 200 will also rotate slightly due to the pressure, thereby reducing the pressure on the passenger's head and improving the riding comfort; when the passenger's overall sitting posture is tilted, the headrest can be rotated as a whole so that the headrest bracket rotates slightly around the center of the arc groove 110 to further adapt to the needs of the passenger and further improve the riding comfort.

[0049] like Figure 3As shown, in the present embodiment, the insertion rod 300 comprises a fixed rod 310 slidably engaged in the arc groove 110 and a rotating rod 320 rotatably connected coaxially with the fixed rod 310; the rotating rod 320 is cylindrical, and a plurality of annular grooves are provided on its upper outer surface; two symmetrically arranged adapter plates 330 are sleeved on the top of the rotating rod 320; a plurality of arc-shaped protrusions meshingly connected with the annular grooves are provided on the lower inner side of the adapter plate 330; a connecting plate 311 extends downwardly from the middle of the bottom surface of the fixed rod 310; the upper part of the adapter plate 330 is clamped on both sides of the connecting plate 311 and fixedly connected to the connecting plate 311 by bolts; when the entire headrest bracket rotates around the center of the arc groove 110, the fixed rod 310 also rotates around the rotating rod 320.

[0050] Preferably, Figure 4 As shown, the two insertion rods 300 are also connected by an elastic structure 800; Figure 5 As shown, the elastic structure 800 includes a spring 810, elastic annular claws 820 connected to both ends of the spring 810, and a retractable decorative cover 830 sleeved outside the spring 810;

In other words, one end of the elastic structure 800 is fixed to the fixed rod 310 of one plug rod 300, and the other end is fixed to the rotating rod 320 of the other plug rod. When the headrest drives the headrest bracket to rotate as a whole, the spring 810 will be stretched or compressed (depending on the direction of rotation). When the pressure of the overall rotation disappears, the position between the plug rods 300 can be restored to the middle position of the seat under the action of the restoring force of the spring 810.
