when the distance between the two pillow plates 12 needs to be increased, the two sliding block portions 22 can be pushed to slide oppositely, so that the extrusion block 2112 is in contact with the movable block 227, the movable block 227 is extruded, the bolt portion 2282 of the locking block 228 is clamped into the locking groove 2274 of the movable block 227, the movable block 227 is located at the escape position and is separated from the clamping with the clamping block 2111, the sliding block portions 22 slide to the initial position under the action of the tensile force of the elastic piece 24, at the moment, the distance between the two pillow plates 12 is the largest, and then the two sliding block portions 22 can be pushed to slide oppositely, so that the required distance between the two pillow plates 12 can be adjusted.

This completes the adjustment process of the vehicle side headrest of the preferred embodiment.

When the slider position of this preferred embodiment's on-vehicle side headrest is located the card and ends the position, through movable block and screens block joint, make slider portion and shell body form the card and end, thereby prevent slider portion to slide to initial position, slider portion slides to when separating the screens by stopping the position, extrude the movable block through the extrusion piece and make its activity to dodge the position, movable block and locking piece joint, thereby remove the card that slider portion and shell body ends the state, then slider portion slides to initial position under the tensile force effect of elastic component, just so need to realize adjusting the position that leans on the headrest board through promoting slider portion to slide, and slider portion slides to separating the screens and can remove the card and end the state and return to initial position, it is very convenient to adjust.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so that the scope of the present invention shall be determined by the scope of the appended claims.

Claims

3. The vehicle side headrest of claim 2, wherein the slider portion further comprises an initial position and an unlocking position at both ends of the locking position on a sliding track, and the slider portion slides from the locking position to the unlocking position to release the locking state, so that the slider portion can slide to the initial position.

4. The vehicle-mounted side sleeping headrest of claim 3, wherein a locking block for limiting the movement of the movable block is movably arranged on the sliding block part;

5. The vehicle-mounted side sleeping headrest of claim 4, wherein a first setting cavity, a second setting cavity, a first spring and a second spring are arranged on the slider part, and the first setting cavity is communicated with the second setting cavity;

the movable block is arranged in the first arrangement cavity in a sliding mode, and the first spring is arranged between the movable block and the inner wall surface of the first arrangement cavity and used for extruding the movable block to slide to the working position;

the locking block is arranged in the second setting cavity in a sliding mode, and the second spring is arranged between the locking block and the inner wall face of the second setting cavity and used for extruding the locking block to extend into the first setting cavity.

6. The vehicle-mounted side headrest of claim 4, wherein an elastic member is connected between the outer shell and the slider portion, an elastic force direction of the elastic member is consistent with a sliding track of the slider portion, and the elastic member is used for pulling the slider portion to slide to the initial position.

7. The vehicle-mounted side sleeping headrest of claim 6, wherein the guide structure further comprises an unlocking block and an extrusion block, the unlocking block and the extrusion block are located at two ends of the clamping block, the unlocking block is used for being in contact with the locking block to extrude the locking block to release the clamping connection between the locking block and the movable block, so that the movable block moves to the working position, and the extrusion block is used for being in contact with the movable block to extrude the movable block to move to the avoiding position.

8.
