The beneficial effect that the present invention reaches:
1. the adjustable fixer of car seat headrest of the present invention, is arranged on the rotational angle of resting the head in rotating shaft by the cooperation control of movable plate and inhibiting device, simple in structure, with low cost, can realize the independent adjusting of headrest, hommization more.
2. pair cannula design T slot, can make inserted link projection be contained in T slot bottom, with T slot oral area sequence, thereby make inserted link be difficult for from intubate, deviate from, peg graft more stable.
3. pair intubate designs the T slot and the square groove that are circumferentially intervally arranged at headrest intubate open end simultaneously, has both been convenient to installing/dismounting, can keep again certain splicing stability.
4. set up slope separately in the oral area both sides of T slot, contribute to slipping into of inserted link projection.
5. by spacing cooperation the between simple fixed plate and movable plate, can stablize the adjusting angle of controlling headrest, simple in structure, take up room little, easily processing, with low cost.
6. limiting stopper is except being parallel to the sheet First of fixed plate, also have along rotor shaft direction and protrude from second of First, so not only increase the thickness of limiting stopper outer end, make limiting stopper more stable with coordinating of spacing stop part, and therefore there is larger thickness without design limiting stopper entirety, can expendable weight, save cost.
7. on limiting stopper, bar shaped convex tendon is set between both sides, can further increase limiting stopper intensity.Especially bar shaped convex tendon is that limiting stopper middle part is outwards swelled and formed, take full advantage of limiting stopper itself, without extra material, and bar shaped convex tendon extends to second by First, make whole limiting stopper there is bending cross section in the direction that is subject to the spacing stop part pressure of fixed plate, can better bear pressure.
8. the shape of limiting stopper both sides matches and can increase area of contact between the two with the profile of corresponding spacing stop part respectively, reduces to impact protection fixed plate and movable plate, the rotational angle that locking movable plate that simultaneously can also be stable also rests the head on.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As Figure 1-3, a kind of adjustable fixer of car seat headrest, comprise and lay respectively at two movable plates 2 that headrest (not shown) both sides are connected with headrest, the vertical rotating shaft 4 that connects two movable plates 2, and drive shaft 4 actuating device (not shown) that drives two movable plates 2 to rotate, the sidepiece of two movable plates 2 is also respectively equipped with can restraint sheet 2 cws and rotate counterclockwise the inhibiting device of angle.Wherein, headrest, with inserted link 1, sets firmly the intubate 6 for plugging inserted link 1 in rotating shaft 4, and intubate 6 can be followed rotating shaft 4 and be rotated.
Concrete, as shown in Figure 5, inserted link 1 is provided with four radial projection 12 of circumferential distribution, and intubate 6 is cylindric for what match with inserted link 1, and open end is provided with four grooves corresponding and each projection 12 coordinates.Concrete, groove comprises two T slots 62 and two square grooves 64, is circumferentially intervally arranged at intubate 6 open ends.Wherein, the width of projection 12 is less than or equal to the oral area width of corresponding T slot 62, is less than the bottom width of T slot 62.Preferably, the oral area width a of T slot 62 is 1.1-1.2 times of projection 12 width b, and the bottom width c of T slot 62 is 3-4 times of T slot 62 oral area width a.The width of square groove 64 is greater than projection 12 width b.
Inhibiting device comprises the fixed plate 8 coordinating with two movable plates 2 respectively, movable plate 2 is provided with the limiting stopper 3 that stretches to corresponding fixed plate 8, and on corresponding fixed plate 8, corresponding being provided with lays respectively at two spacing stop parts 82 that limiting stopper 3 clockwise rotates direction and rotates counterclockwise direction.Concrete, two fixed plates 8 be arranged in parallel, and two movable plates 2 are located at respectively two fixed plate 8 inner sides.For example motor of actuating device is arranged on rotating shaft 4 one end by techniques well known, can drive movable plate 2 to rotate with respect to fixed plate 8 by rotating shaft 4, thus adjusting head cornu occipitale degree.Movable plate 2 upper ends arrange limiting stopper 3, and fixed plate 8 upper ends arrange two spacing stop parts 82 that coordinate with limiting stopper 3.More specifically, limiting stopper 3 comprises second 34 that is parallel to the sheet First 32 of fixed plate 8 and protrudes from First 32 along rotating shaft 4 directions.Limiting stopper 3 also comprises the sidepiece 36 coordinating with two spacing stop parts 82 respectively, on limiting stopper 3, be provided with bar shaped convex tendon 38 between both sides 36, bar shaped convex tendon 38 for limiting stopper 3 middle parts outwards protuberance form, extend to second 34 by First 32.The bearing of trend that on First 32, the bearing of trend of bar shaped convex tendon 38 points to bar shaped convex tendon 38 in 4, the second 34 of rotating shafts is parallel to rotating shaft 4.In addition, the shape of limiting stopper 3 both sides 36 matches with the profile of corresponding spacing stop part 82 respectively.
When installation, headrest inserted link 1 is aimed to the intubate 6 of adjustable fixer and pegged graft, wherein projection 12 snaps in respectively in corresponding groove, stablizes this grafting, prevents the relative rotation between inserted link 1 and intubate 6.Concrete, when projection 12 snaps in T slot 62, first enter from T slot 62 oral areas, then to T slot 62 bottoms, then rotate inserted link 1, make projection 12 and T slot 62 oral area dislocation in T slot 62, thereby comparatively stable lock tab 12 is in T slot 62.Easy to operate, firm plug.
When work, order about headrest Angulation changes thereby actuating device drives movable plate 2 to rotate, while resistance by fixed plate 8 upper limit stop parts 82 to movable plate 2 upper limit position blocks 3, locking angle, is used the angular adjustment automation of this adjusting part, stable, convenient.
Embodiment 2
As Fig. 1-4, a kind of adjustable fixer of car seat headrest, is with the difference of embodiment 1: the oral area both sides of T slot 62 are set up slope 622 separately, and when inserted link 1 is installed, projection 12 easily slips in groove.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
