The automobile seat headrest adjusting mechanism comprises a headrest height electric adjusting mechanism and a headrest front-back translation electric adjusting mechanism, wherein a headrest rod of the headrest front-back translation electric adjusting mechanism is fixed on a headrest rod support of the headrest height electric adjusting mechanism by virtue of two Omega-shaped springs. The automobile seat headrest adjusting mechanism disclosed by the invention has the advantages that structure is novel, the headrest height electric adjusting mechanism and the headrest front-back electric adjusting mechanism are integrated, a four-directional adjusting mechanism is systematacially integrated, and comfort is provided for passengers to the utmost extent. Front-back translation distance of a headrest can reach up to 60mm, compared with the traditional headrest without front-back adjustment and the headrest which adjusts a front-back position by utilizing rotation, translation for 60mm can meet comfort requirement of people in different percentiles and the people with different head styles to the utmost extent.
Description
Technical field
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.
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.
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.Their height and position setting range, front and back position setting range are almost consistent; That is to say that their traveling comfort almost is consistent.The existing manual car seat headrest that these have four way control all is a complex structure, costs an arm and a leg, and is inappropriate on general car and promotes the use of.
Summary of the invention
The present invention provides a kind of car seat headrest regulating mechanism that is used for up and down with the front and back motorized adjustment, 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 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;
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;
Advantage of the present invention is: novel structure, combine motorized adjustment mechanism before and after the electronic regulating mechanism of height, headrest of headrest, the system integration four way control 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.
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.
