Two kinds of forms of the general employing of the employed elevation and subsidence regulating device of manned vehicle front-row seats in the market.One of which utilizes a kind of manual clutch apparatus, carries out height adjustment through making the handle up-and-down movement.This manual clutch device volume is big, quality is big, component parts is complicated, and this non-continuous movement can produce bigger noise in its motion process.Its two, utilize handwheel or motor driven connecting rod mechanism movement to regulate, this device operating effort is big, tolerance clearance is big, realizes that the seat cushion lifting needs auxiliary connecting rod mechanism to come transmission of drive force.
Summary of the invention
The purpose of this invention is to provide a kind of vehicle seat elevation and subsidence regulating device, to overcome composition complicacy, the structure technical matters huge, the big operating effort of needs when regulating that present jacking system exists.
To achieve these goals, technical scheme of the present invention is following:
A kind of vehicle seat elevation and subsidence regulating device comprises: eccentric drive shaft; Fixed tooth plate which is provided with first inner gear; The rotation tooth plate which is provided with secondary annulus; This rotation tooth plate is embedded in said fixed tooth plate; Gear is set on the said eccentric drive shaft; This gear meshes with said first inner gear, secondary annulus simultaneously; Said gear, fixed tooth plate and rotation tooth plate are connected on the said eccentric drive shaft.
Said eccentric drive shaft is hollow eccentric drive shaft, and a connecting pin is located in the said hollow eccentric drive shaft, and said gear, fixed tooth plate and rotation tooth plate are fixed on the said eccentric drive shaft.
Said eccentric drive shaft is hollow eccentric drive shaft, and a connecting pin is located in the said hollow eccentric drive shaft, and said gear, fixed tooth plate are fixed on the said eccentric drive shaft; Said rotation tooth plate is fixed in said eccentric drive shaft one end.
Said gear is dual gear or individual gears.
Said fixed tooth plate is fixed on the seat frame skeleton connecting panel of automotive seat.
Said rotation tooth plate is connected with the last slide rail of the chair slide of automotive seat.
The present invention reforms on existing vehicle seat lifting and lowering mechanism basis; Utilized the coupling between hollow eccentric shaft, gear, fixed tooth plate, rotation tooth plate and the connecting pin to connect; Formed vehicle seat elevation and subsidence regulating device self-lock force is big; Strengthened robust motion, reliability and the safety of jacking system, and make simple, available manually or the motorized motions mode drive.

The specific embodiment
According to Figure 1A to Fig. 7, provide preferred embodiment of the present invention, and describe in detail below, enable to understand better function of the present invention, characteristics.
As depicted in figs. 1 and 2, vehicle seat elevation and subsidence regulating device of the present invention comprises eccentric drive shaft 1; Fixed tooth plate 3 which is provided with first inner gear 31; Rotation tooth plate 4 which is provided with secondary annulus 41; This rotation tooth plate 4 is embedded in said fixed tooth plate 3; Gear 2 is set on the said eccentric drive shaft 1.Said gear 2, fixed tooth plate 3 and rotation tooth plate 4 are connected on the said eccentric drive shaft 1.
Fig. 7 is the gear while and first inner gear, secondary annulus ingear scheme drawing in the elevation and subsidence regulating device of the present invention.As shown in Figure 7, gear 2 simultaneously with said first inner gear 31, secondary annulus 41 engagements.Gear 2 can be the dual gear shown in Figure 1A, also can be the individual gears shown in Figure 1B.
Fig. 3 and Fig. 4 have shown the preferred connection mode between gear 2, fixed tooth plate 3 and rotation tooth plate 4 and the eccentric drive shaft 1 in the vehicle seat elevation and subsidence regulating device of the present invention.As shown in Figure 3, said eccentric drive shaft 1 is that hollow eccentric drive shaft 1, one connecting pin 5 is located in the said hollow eccentric drive shaft 1, and said gear 2, fixed tooth plate 3 and rotation tooth plate 4 are fixed on the said eccentric drive shaft 1.Obviously, rotation tooth plate 4 also can directly be fixed in said eccentric drive shaft 1 one ends, is located in the said hollow eccentric drive shaft 1 through connecting pin 5 then, and said gear 2, fixed tooth plate 3 are fixed on the said eccentric drive shaft 1.Said fixed tooth plate is fixed on the seat frame skeleton connecting panel 91 of automotive seat.Said rotation tooth plate 4 is connected with the last slide rail 93 of the chair slide 92 of automotive seat.
Rotate when the power input makes hollow eccentric drive shaft 1 produce, gear 2 is and then rotation also.Form the transmission of difference tooth between gear 2 rotation backs and fixed tooth plate 3 and the rotation tooth plate 4,4 rotations of driven rotary tooth plate.Suppose that gear 2 is 21 teeth, fixed tooth plate 3 internal tooths are 23 teeth, and rotation tooth plate 4 is 24 teeth, and the transmitting ratio of formation is 24: 1, and promptly the motion input end drives hollow eccentric drive shaft 1 rotation 24 circles, and rotation tooth plate 4 rotates 1 circle.4 of rotation tooth plates move thereby drive seat frame skeleton around Fig. 5 and center P rotation shown in Figure 6 together, realize the purpose of up-down.
