Description
Technical field
But the present invention be a kind of realize up and down electronic adjustment of height, level can before and after the car seat headrest adjusting mechanism of electronic adjustment and both wings front and rear angles hand adjustment.
Background technology
Flourish along with automobile industry, people have higher requirement to the traveling comfort of automotive seat.Car seat headrest is as product comparatively special in the automotive seat, and except the security functions that possesses the protection human body head, people also require it to possess higher traveling comfort.The different crowd of height has proposed adjustable requirement to the height and position of car seat headrest, and for example the women of the 5th hundredths requires chair headrest can reduce to adapt to its sitting posture; Different people have also proposed adjustable requirement to the front and back position of car seat headrest, and the women who for example plaits one's hair requires headrest to regulate or the like backward; Along with the raising of seat comfort, recently people have higher requirement, promptly the occupant rest the head in bed flank can before and after rotate to support the head of human body.
Have six actually rare to the chair headrest structure of regulating, only existing on high-end automotive seat on the present global automotive seat market.It all is complex structure that existing these have the six manual car seat headrests to adjusting, costs an arm and a leg, and is inappropriate on general car and promotes the use of.
Summary of the invention
The present invention provide a kind of car seat headrest six to motorized adjustment mechanism, to solve complex structure that existing manual regulation car seat headrest exists, to cost an arm and a leg, be inappropriate for the problem of on general car, promoting the use of.
The technical scheme that the present invention takes is: comprise height of headrest motorized adjustment mechanism; Translation motorized adjustment mechanism and headrest both wings angle manual adjustment means before and after the headrest; The head rest pole of translation motorized adjustment mechanism is fixed on the head rest pole support of height of headrest motorized adjustment mechanism through 2 Ω shape springs before and after the headrest, and the headrest front carriage of translation motorized adjustment mechanism connects and fixes together before and after headrest two wing supports of headrest both wings angle manual adjustment means and the headrest;
The structure of described height of headrest motorized adjustment mechanism is: motor is captiveed joint with the cushion frame upper junction plate through 4 screws with frame; Motor output shaft is a leading screw; Feed screw nut is connected through 2 screw retention with the head rest pole support, and feed screw nut is connected with threads of lead screw, and stop nut is captiveed joint with the leading screw end thread; 2 head rest poles are captiveed joint chute on the head rest pole support and the guide rail sliding block joint on the frame respectively through 2 Ω shape springs with the head rest pole support;
The structure of translation motorized adjustment mechanism is before and after the described headrest: head rest pole is fixed on the headrest middle bracket through 2 elastic cylindrical pins; Motor passes through 3 screw retention on the headrest middle bracket; Motor output shaft is a leading screw; Through nut leading screw is captiveed joint with the headrest front carriage, 3 rack frames connect and fix together with the headrest front carriage respectively, and these 3 rack frames are formed three groups of pinion and racks through corresponding 3 gear wheel shafts respectively with the headrest middle bracket; 4 rotating shaft pincers connect and fix together with back cover respectively, and gear wheel shaft connects together through rotating shaft pincers and the back housing assy that is made up of rotating shaft pincers, back cover;
The structure of described headrest both wings angle manual adjustment means is: left and right sides both wings are symmetrical mechanism; Existing is that example describes with the left wing: inlay rotating shaft in two wing supports of resting the head on; Bloated riveting nut is riveted on the card spring, and card spring and rotating shaft are rotationally connected, and the flank header board is captiveed joint with the card spring through the screw and the riveting nut that expands; Flank back cover and flank header board connect and fix together, and two wing supports of resting the head on connect and fix together with the headrest front carriage.
Advantage of the present invention is: novel structure, combine motorized adjustment mechanism and headrest both wings manual angle adjusting mechanism before and after the electronic regulating mechanism of height, headrest of headrest, the system integration six to regulating mechanism, the traveling comfort of maximum possible is provided for the occupant.The front and back translation distance of headrest can reach 60mm, compares the headrest that tradition regulates before and after not having and utilizes and rotate the headrest of regulating front and back position, and translation 60mm can satisfy people's the traveling comfort requirement of people and the different head dummys of different hundredths to the full extent.Headrest was to the support of head when the adjusting of both wings can be satisfied occupant's rest.
The 60mm that moves forward is very thorny for the layout of part for headrest, if headrest is done as a whole moving forward, is that the intensity and the inner structure of the headrest of 100mm almost can't realize to thickness so; If back cover is motionless, after fore shell moved forward 60mm so, the integral thickness of headrest was 160mm; Monnolithic case seems again, and some is too fat to move thick and heavy, and through design cleverly, front and back are regulated and adopted pinion and rack; It is the half the of tooth bar miles of relative movement that gear wheel shaft moves distance, and back cover is connected with gear wheel shaft, like this fore shell 60mm that moves forward; The back cover 30mm that under the drive of gear wheel shaft, moves forward then; This structure has guaranteed that the position relation of each part is reasonable in the motion process, and has practiced thrift the space to the full extent, makes the complicated headrest profile of inner structure be unlikely to excessive.
The present invention adopts motor-driven, to the full extent for the passenger provides comfort feature, and general manual regulation, complicated, the effort of its method of operation, and motorized adjustment mechanism, the passenger only need press button, can realize that just the front and back translation of resting the head on regulates, and is easy and convenient.Translational controlling mechanism reliability and accuracy at an arbitrary position before and after motor-driven has also guaranteed.
Electronic height adjustment mechanism is built in the back of seat, and electronic front and back regulating mechanism is built in the headrest, through the rational deployment of structure, realized multi-functional integrated in, guaranteed that also the headrest profile is unlikely to excessive, handsome in appearance.
Press the height that button comes the motorized adjustment headrest through the occupant, front and back position improves occupant's traveling comfort.The present invention is simple in structure, and is with low cost, and noise is low, and reliability is high, and traveling comfort is good, in durability test cycle, does well, and daily service free is safeguarded.
