Description
Technical field
A kind of sealing structure of the continuous recliner of automotive seat is the utility model is related to, and the recliner is to realize automobile
The device of seat back angle regulation.
Background technology
The continuous recliner of automotive seat is that one kind is arranged on automotive seat, realizes that motor vehicle seat back angle is continuous continuously
The part of disconnected regulation.
" a kind of automotive seat angle modulation of differential teeth planetary gear internal messing disclosed in Chinese patent CN2012101407425
The application for a patent for invention of device ", it is to eliminate radial clearance to two wedge tensioners by spring, and it is mainly characterized by：Two wedge shapes
Block is located in the die cavity that axle sleeve and hole flanging boss are formed, and wherein wedge side contacts with axle sleeve, opposite side and hole flanging
Boss contacts；Backrest, cushion are connected with recliner internal gear, the boss of outer tooth plate two respectively.It is limited to recliner design knot
Structure, its using when have the following disadvantages：The recliner is because inside and outside tooth plate outside is without sealing protection, when surface electrophoretic process
When, paint solution is easily accessible inside, and influenceing built-in function causes recliner to fail.
Utility model content
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency in the presence of prior art, and provides one
The sealing structure of the kind structure design more reasonably continuous recliner of automotive seat, it will not cause recliner to be lost because of sealing problem
Effect.
Technical scheme is used by the utility model solves above-mentioned technical problem：The continuous recliner of the automotive seat it is close
Seal structure, it is characterised in that：Described sealing structure is axial seal structure, and a sealing is provided with the axial seal structure
Ring, the sealing ring contacted with the axle sleeve of recliner and with the actuator plane contact of recliner, for actuator and shaft room
Sealing.
Axial seal structure described in the utility model also includes pad and packing ring, and described pad is enclosed on the cylinder of outer tooth plate
On shape boss, and it is allowed to seal between outer tooth plate and bag circle；Described packing ring contacts with internal gear, for actuator with it is interior
Sealing between tooth plate.
The utility model is additionally provided with Spring Card, and it produces axial compression with washer contacts and with actuator clamping.
The utility model compared with prior art, has advantages below and effect：Using axial compression Seal Design, make seat
The structure design of chair recliner is more reasonable, better tightness, and service life is longer；When carrying out surface electrophoretic process, paint solution
Inside is not easily accessible, does not interfere with the normal function of recliner.
Brief description of the drawings
Fig. 1 is to illustrate expanded view with recliner overall structure of the present utility model.
Fig. 2 is the structural representation in another direction of Fig. 1.
Fig. 3 is the structural representation sectional view after Fig. 1 combinations.
Fig. 4 is the schematic diagram of the structure for amplifying namely the utility model sealing structure in Fig. 3 at A.
In figure：1 internal gear, 2 outer tooth plates, 3 axle sleeves, 4,5 wedges, 6 eccentric wheels, 7 springs, 8 pads, 9 bag circles, 10 sealings
Ring, 11 actuators, 12 packing rings, 13 Spring Cards, circular bottom surface in 102 internal gears, 21 outer tooth plate tubular boss, 11a actuator boss,
11d actuator planes.
Embodiment
Referring to Fig. 1-Fig. 4, the present embodiment is for being provided with exemplified by the continuous recliner of the automotive seat of clearance eliminating mechanism
It is illustrated, but it is also applied for common angle regulating device for seat of vehicle.Meanwhile understand for convenience, it is mutually right in present specification
The part of title or position use identical title, but are distinguished by with different labels.
In the present embodiment, to define axle sleeve hollow by Y-direction installation for the outer tooth plate 2 in recliner, internal gear 1, axle sleeve 3
Inner space, wherein outer tooth plate 2 engages with internal gear 1；Outer tooth plate 2 uses cylindrical structure, i.e., the outer ring of outer tooth plate 2 is directly designed
For tooth form, inner circle pulls into cylindrical structure, makes the appearance and size of recliner small, in light weight.
Axle sleeve 3 is placed in internal gear in circular bottom surface 102, and bag circle 9 connects firmly with internal gear 1.
Radially, clearance eliminating mechanism includes：Wedge 4,5, eccentric wheel 6, spring 7.The clearance eliminating mechanism is upper and lower
Two layersth, double-cam structure, eccentric wheel 6 are in one layer, and as fixed cam, and two wedges 4,5 are in another layer, composition activity
Cam；Two legs are separately mounted to by the eccentric wheel window on eccentric wheel 6 in the wedge breach of wedge 4,5 on spring 7；
Whole clearance eliminating mechanism is located in axle sleeve 3.
When driving one of wedge, friction is produced between the wedge and eccentric wheel 6, rotates eccentric wheel 6, from
And reduce driving sluggishness, improve integrally-built flexibility during adjusting and eliminate gap.
When recliner is moved, it is described as follows by taking clockwise movement as an example：Actuator 11 drives wedge 4, and wedge 4 compresses
Spring 7, while using friction belt movable eccentric wheel 6, wedge 5 rotates together in the presence of spring 7, while outer tooth plate 2 is around interior
The engagement rotation of tooth plate 1 realizes the regulation of angle.
Referring to Fig. 4, an axial seal structure is provided with recliner, it includes pad 8, sealing ring 10 and packing ring 12,
Pad 8 is enclosed on outer tooth plate tubular boss 21（Referring to Fig. 1）, and be allowed to seal between outer tooth plate 2 and bag circle 9；Sealing ring
10 contact with axle sleeve 3 and are contacted with the actuator plane 11d of actuator 11, for the sealing between actuator 11 and axle sleeve 3；Packing ring
12 contact with internal gear 1, for the sealing between actuator 11 and internal gear 1；Meanwhile Spring Card 13 is additionally provided with, it and packing ring
12 contacts simultaneously produce axial compression with the clamping of actuator 11.Thus, when recliner carries out surface electrophoretic process, paint solution is just not easy
Into inside, built-in function will not be impacted, will not also cause recliner to fail.
By foregoing description, those skilled in the art can implement.
The title that the utility model above parts are taken can be different, all that described structure is conceived according to the utility model patent
Make, the equivalent or simple change that feature and principle are done, be included in the protection domain of the utility model patent.
