[0026] The auxiliary sleep adjustment headrest of the present invention will be further described below in combination with specific embodiments to help those skilled in the art to have a more complete, accurate and in-depth understanding of the technical solution of the present invention.

[0027] Example 1

[0028] like Figure 1-10 As shown, the auxiliary sleep adjustment headrest of this embodiment includes a rear shell 1, a front shell 3, a side wing soft covering 2, a side wing assembly and a headrest guide rod 4. The side wing soft covering 2 is arranged on both sides of the front shell 3, and the side wing soft covering 2 can rotate relative to the rear shell 1. The side wing assembly includes a side wing frame 5 arranged on both sides of the rear shell 1, and the side wing soft covering 2 is covered on the outer surface of the side wing frame 5 so that the side wing soft covering 2 can flexibly contact the head. The side wing frames 5 on both sides are symmetrical to each other based on the central symmetry plane of the headrest. The side wing frame 5 is installed on a circular shaft 8, and a locking hole 51 and a reset guide 52 are provided on the side wing frame 5, and an inclined surface extending to the locking hole 51 is provided on the reset guide 52. The shaft 8 is connected to the base plate 15 through a bracket 11. The base plate 15 is welded to the guide rod 4. The locking rod 13 is inserted into the locking hole 51 of the wing frame 5 to lock the position of the wing. When the locking rod 13 is separated from the locking hole 51 of the wing frame 5, the locking of the wing frame 5 can be released. When the wing frame 5 is reset, the locking rod 13 can slide into the locking hole 51 along the inclined surface of the reset guide 52 to lock the wing frame 5. Fig.10As shown. The locking rod 13 is fixed to the base plate 15 through the bracket 11 and the turntable 14. A through button 12 is provided on the outside of one side of the rear shell 1, and the button 12 is sleeved on one end of the shaft rod 8. The turntable 14 rotates with the locking rod 13 through the turntable shaft 16. The turntable 14 is connected to the base plate 15 through the turntable mounting shaft 17. The turntable 14 rotates around the turntable mounting shaft 17 to drive the locking rod 13 to move left and right along the vehicle width direction to lock or unlock the side wing frame 5. The lever 9 is fixed to the shaft rod 8, and the lower side of the lever 9 has a U-shaped groove, which cooperates with the turntable shaft 16, and the turntable shaft 16 can slide in the U-shaped groove. The lever 9 is also connected to the base plate 15 through a reset spring 10. In the absence of external force, as Figure 5 As shown, the lever 9 is fixed in the initial position under the pulling force of the return spring 10 and the blocking action of the limit plate 18 of the bottom plate 15. The shaft 8 is provided with a compression spring 7, the first end 71 of the compression spring is clamped on the side wing frame 5, and the second end 72 of the spring 7 is clamped on the bracket 11. In the initial position where the side wing frame 5 is locked, the compression spring 7 is pre-compressed. When the side wing frame 5 is unlocked, the compression spring 7 provides elastic force to cause the side wing frame 5 to rotate outward. Fig. 9 As shown, the side wing frame 5 is fixed with a sliding sleeve 20 by bolts 19. The sliding sleeve 20 is arranged in the arc-shaped slide groove of the travel plate 6. The sliding sleeve 20 can slide back and forth between the first end 61 and the second end 62 of the slide groove. The initial position of the sliding sleeve 20 is at the first end 61 of the slide groove. The travel plate 6 is welded to the bottom plate 15. The swinging amplitude of the side wing frame 5 is limited by the length of the slide groove of the travel plate 6.

[0029] When the finger pushes the button 12 to move inside the headrest, it drives the shaft 8 to move together, and the lever 9 fixed on the shaft 8 will simultaneously push the turntable 14 to rotate around the turntable mounting axis 17. During the rotation of the turntable 14, it drives the locking rod 13 to move toward the center of the headrest. The locking rod 13 disengages from the locking hole 51 of the frame 5. The side wing frame 5 rotates around the central axis of the shaft 8 under the elastic force of the compression spring 7, and the lower part of the side wing frame 5 rotates and extends forward. While the side wing frame 5 extends forward, the sliding sleeve 20 thereon stops in the sliding groove of the stroke plate 6 from the first end 61 to the second end 62. The side wing frame 5 maintains the maximum extension amount under the limitation of the spring force and the second end 62. The side wing soft covering 2 on the side wing frame 5 provides lateral support for the head, such as Figure 2 in the expanded state.

[0030] When the head needs lateral support, after the button 12 on the side of the headrest is pressed by the finger, the side wing frame 5 loses its locking force, and the side wing frame 5 pops outward, and the soft covering 2 thereon can provide lateral support to the head. Since the length of the headrest side wing can be customized in the up and down directions according to the needs during the initial design, there is no need to make the headrest width very wide, so as not to occupy the space in the vehicle width direction inside the vehicle. The side wing can extend forward to exceed the center point of the head, and the lateral projection point of the center of gravity of the head can fall within the range of the side wing. It can provide wider support for the side of the head. When the vehicle is hit from the side, the lateral support that exceeds the range of the center of gravity of the head can also protect the occupant's head. Reduce the damage to the head caused by side collision.

[0031] For ordinary technicians in this field, the specific embodiments are only illustrative descriptions of the utility model. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, they are all within the protection scope of the utility model.
