Abstract
The invention relates to an electric adjusting mechanism for adjusting the headrest of a cart set frontward and backward. A headrest rod is fixed on a middle support of the headrest through two elastic cylindrical pins; a motor is fixed on the middle support of the headrest through three bolts; a screw is used as the motor output shaft; the screw is fixedly connected with a front support of the headrest through a nut; three rack frames are respectively clamped with the front support of the headrest, and form three groups of gear-rack mechanism through three gear shafts together with the middle frame of the headrest, respectively; four shaft pincers are respectively clamped with a rear case; and the gear shafts are connected with a rear case assembly consisting of the shaft pincers and the rear case through the shaft pincers. The electric adjusting mechanism provided by the invention is novel in structure, can ensure that the moving distance of the rear case is half that of the front case so as to ensure the moving stability, and is convenient and easy in adjusting the headrest frontward and backward in the horizontal direction, thereby improving the comfort, and ensuring the reliability and accuracy of the horizontal adjusting mechanism at any positions.
Description
Technical field
The present invention be a kind of horizontal direction can before and after the electronic adjusting mechanism of car seat headrest regulated.
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 people of head dummy 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 adjust or the like backward.
Can realize on the present global automotive seat market horizontal direction can before and after the chair headrest structure of regulating basically all be to utilize to rotate seesawing of realizing resting the head on, their in the horizontal direction the front and back position scope of regulating almost be consistent.Existing these realize that through rotating the electric headrest of regulating before and after the horizontal direction all is a complex structure, cost an arm and a leg, and are inappropriate on general car and promote the use of.
Summary of the invention
The present invention provides a kind of electronic adjusting mechanism that car seat headrest is regulated in front and back that is used for, and to solve the complex structure that present adjusting mechanism exists, costs an arm and a leg, and is inappropriate for the problem of on general car, promoting the use of.
The technical scheme that the present invention takes is: 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 present invention can satisfy different occupants' traveling comfort through the front and back translation of the transmission device realization headrest of motor-driven headrest.The front and back translatory distance of headrest can reach 60mm; Compare that tradition does not have the headrest of fore-and-aft adjustment and to rotate the headrest adjust front and back position, the people that translation 60mm can satisfy different hundredths and different head dummys to the full extent is provided with the different headrests and the gap width of head.
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.
Advantage of the present invention is: novel structure, utilize gear & rack structure, and realize that the distance that back cover moves is the half the of fore shell miles of relative movement.Guaranteed the stationarity of motion simultaneously.Adopt motor-driven, farthest for the occupant provides comfort feature, general manual regulation; Complicated, the effort of its method of operation, and motorized adjustment mechanism, the occupant only need press button; Just can realize the front and back horizontal adjustment of resting the head on; Easy and convenient, improved occupant's traveling comfort, motor-driven has also guaranteed level(l)ing mechanism reliability and accuracy at an arbitrary position.
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.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
The motor-driven leading screw drives fore shell and realizes seesawing, and when fore shell moved forwards or backwards, gear wheel shaft drove the back housing assy and moves forwards or backwards, and the distance of its motion is the half the of fore shell move distance, sees Fig. 8.
