Description
Technical field
The utility model relates to angle regulator for automobile chair assembly, specifically a kind of angle regulator for automobile chair assembly strengthening recliner intensity.
Background technology
The regulating mechanism raised after leaning forward for all kinds of motor vehicle seat back is called recliner.Usually, recliner, by the adapter plate connecting seat cushion framework, connects the portable plate of backrest, and can the regulating mechanism of relative angle between adjustment fixing plate and portable plate, the composition such as return spring and bar handle.In recliner assembly product, regulating mechanism plays a part very crucial, and he should the angle of adjusting seat backrest, guarantee the locking intensity of backrest angle again, also will ensure the safety of driver and conductor, therefore, the quality of recliner product design, key is the quality of regulating mechanism.
As application number is: 2012102059689 the invention discloses a kind of internal messing disc like device for adjusting angle of chair core apparatus, comprise disk (1), torsion spring (2), driver plate (5), circular tooth disk (6) and involucrum (7); Also comprise little tooth plate (3) and cam (4); Little tooth plate and cam are installed in disk; The inner peripheral surface of little tooth plate is provided with the first curve convex surface (3-1) and the second curve convex surface (3-5); Cam is irregular roundness plate-like, is provided with locking face group and at least one stationary plane of at least one group at its cylindrical; Locking face and curve convex surface free-running fit; Locking face group comprises the first locking face and the second locking face; First locking face and the first curve convex surface free-running fit; Second locking face and the second curve convex surface free-running fit.Advantage structure interval of the present invention is little; This core members gap obviously reduces and becomes two-point contact locking from an original point cantact locking; Load-carrying capacity is large.This core members structure is ingenious, and manufacturing process is simple, and reliable product quality is stablized, and manufacturing cost is low.
Locking guide groove plate three is for the boss of fixing seat cushion framework connecting panel, due to long-pending few with the contacting section in connecting panel three holes, when back of seat is subject to certain torsional pulse power, the boss of about about 1.5% can under the effect of impulsive force, shear interconnective material fiber gradually, finally together with connecting panel one piece, come off from the parent of locking guide groove plate, cause recliner disabler, and potential larger potential safety hazard.The gear ring position of dish internal tooth ratchet, can only carry the axial impact force of about 3000 ㎏.
This kind of disc type regulating mechanism is generally made up of dish-shaped internal tooth ratchet, locking tooth plate, locking cam, dish type return button spring, lock tooth guide groove plate, axle sleeve, anchor ear etc.Due to the variety of inner structure, the complexity of manufacturing process, causes this type of regulating mechanism mostly to exist rocking excessive clearance, load-carrying capacity is on the low side, the defect such as poor reliability, easily inefficacy.Particularly locking guide groove plate and dish-shaped internal tooth ratchet, because adopting cold-rolling thin plate, apply accurate continuous stamping process, the structure of shaping rear formation different levels, and the slippage fiber only do not sheared by plate stretch is between layers connected, and when the boss be fixedly connected with and interior toothed ring gear are subject to larger axial impact force or radial tersional stress, can come off or be out of shape between layers, make the disabler of recliner, and potential larger potential safety hazard.
Summary of the invention
The intensity defect that the utility model exists to effectively solve this disc type regulating mechanism, a kind of angle regulator for automobile chair assembly strengthening recliner intensity of special proposition.
The technical solution of the utility model is for this reason, a kind of angle regulator for automobile chair assembly strengthening recliner intensity, comprise step rotating shaft, described step rotating shaft passes from dish-shaped internal tooth ratchet, and be provided with dish type pull back spring successively, locking cam, locking tooth plate passes from locking guide groove plate, become as a whole finally by anchor ear, it is characterized in that: described dish-shaped internal tooth ratchet shell is made for the housing of four steps, first step, second step, 3rd step, 4th step is four levels be parallel to each other, dish-shaped internal tooth ratchet cross section circular arc between layers is also increased thereupon, interconnective slippage fibre section is amassed and is not less than material thick 35% between layers.
Further improvement is: wherein first step and second step form convex arc-shaped transitional surface at inner chamber.
Further improvement is: the shell of locking guide groove plate is provided with the second boss on the circular flat of the first boss, makes material thickness constant, and the bottom-to-top-height of locking guide groove plate increases.
Beneficial effect:
The gear ring position of the utility model dish internal tooth ratchet, can carry the axial impact force of about 5000 ㎏, greatly improve the property indices of recliner assembly product.
First step and second step form convex arc-shaped transitional surface at inner chamber, nethermost intensity is increased, and the motion of available protecting dish type return torsion spring and locking tooth plate is not interfered.
The circular flat of the first boss of locking guide groove plate increases by the second boss again, the bottom-to-top-height of locking guide groove plate is made almost to add one times, with recliner seat cushion framework connecting panel be fixed be connected time, the cross section of its contact increases greatly, thus, increase the intensity of recliner opposing tersional stress.
