Abstract
An improvement on a core component of an automobile chair angle adjuster relates to the field of automobile interior trim parts, and comprises a sector, a ratchet and a shifting block, wherein the ratchet is arranged between the sector and the shifting block; a sector rotating shaft penetrates the sector, a ratchet rotating shaft penetrates the ratchet, and a shifting block rotating shaft penetrates the shifting block; a locking groove contacted with the shifting block is arranged on one side of the ratchet, and a meshing gear is manufactured on the other side of the ratchet; a first contact and a second contact which are locked mutually with the front end of the shifting block are arranged on the locking groove; a meshing gear is also manufactured on the edge of the sector and meshed with one side of the meshing gear manufactured on the ratchet. Compared with the prior art, the improvement on the core component of automobile chair angle adjuster has a more reasonable structure, improves the structure dimensions of the combined part of the shifting part and the ratchet, and enables the shifting block to open the ratchet with less effort and lock the ratchet more safely.
Description
Technical field:
The utility model relates to the automotive upholstery field, specifically is a kind of improvement of core component of angle regulator for automobile chair.
Background technology:
In the prior art, the core component that is used for automotive seat, comprise fan tooth, the rotating shaft of fan tooth, ratchet, ratchet rotating shaft, shifting block, shifting block rotating shaft, because the structure design of shifting block and ratchet mating part is reasonable inadequately, the locking that is related to angle regulator for automobile chair is conciliate the function of two most criticals of locking, existing this product exists the phenomenon that recliner can't lock and do not open because the shifting block front end is shorter when interacting with ratchet, these all are very fatal shortcomings (as Fig. 1 and Fig. 2).
The utility model content:
The utility model purpose provides a kind of improvement of core component of angle regulator for automobile chair, is used for improving the in-use performance and the safety of angle regulator for automobile chair.
The utility model is that the technical scheme that is adopted that achieves the goal is:
A kind of improvement of core component of angle regulator for automobile chair, by the fan tooth, ratchet and shifting block constitute, ratchet is arranged between fan tooth and the shifting block, on described fan tooth, pass the rotating shaft of fan tooth, pass the ratchet rotating shaft on the ratchet, pass the shifting block rotating shaft on the shifting block, it is characterized in that: be shaped on the side of described ratchet and the contacted lock groove of described shifting block, be shaped on grinding tooth on the opposite side, on described lock groove, be provided with first contact and second contact with the mutual locking of described shifting block front end, the edge of described fan tooth also is shaped on grinding tooth, and is shaped on the described ratchet between the side of grinding tooth and is meshing with each other.
Described shifting block front end is the circular arc feeler of sleeve configuration.
The utility model is adjusted the position of lock groove upper contact on shifting block front end and the ratchet by rotating shifting block in use, the engagement between control ratchet and the fan tooth with separate, reach the purpose of locking and release, further the recliner of Control of Automobile seat.
Principle of work is the adjustment of motor vehicle seat back angle, make angle regulator for automobile chair handle released state earlier, driving ratchet by shifting block rotates around the ratchet rotating shaft, when the center-point three point on a straight line of ratchet and shifting block contact point and shifting block rotating shaft center-point and ratchet rotating shaft, to form the dead point, this moment, ratchet separated with the fan tooth, the back of seat angle can be adjusted, when back of seat is adjusted angle, then shifting block will be under the effect of relevant pull back spring return, driving ratchet by shifting block rotates around ratchet rotating shaft return, when the center-point three point on a straight line of ratchet and shifting block contact point and shifting block rotating shaft center-point and the rotating shaft of fan tooth, to form the dead point, ratchet and the engagement of fan tooth at this moment, this is with regard to the lockup state of seat recliner.
The beneficial effects of the utility model are compared with prior art, and structure is more reasonable, have improved the scantling of structure of shifting block and ratchet mating part, and it is more laborsaving to make shifting block open ratchet, and shifting block locking ratchet is safer.
Description of drawings:
Fig. 1 is scheme drawing during lockup state in the prior art;
Fig. 2 is scheme drawing during released state in the prior art;
Scheme drawing when Fig. 3 is the utility model lockup state;
Scheme drawing when Fig. 4 is the utility model released state.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 3, a kind of improvement of core component of angle regulator for automobile chair, by fan tooth 1, ratchet 2 and shifting block 3 constitute, ratchet 2 is arranged between fan tooth 1 and the shifting block 3, on fan tooth 1, pass fan tooth rotating shaft 11, pass ratchet rotating shaft 21 on the ratchet 2, pass shifting block rotating shaft 31 on the shifting block 3, wherein be shaped on the side of ratchet 2 and shifting block 3 contacted lock grooves 22, be shaped on grinding tooth on the opposite side, first contact 23 and second contact 24 with shifting block front end 3 mutual lockings are arranged on the lock groove 22, shifting block 3 front ends are the circular arc feelers 32 that are sleeve configuration, edge at fan tooth 1 also is shaped on grinding tooth, and is shaped on the ratchet 2 between the side of grinding tooth and is meshing with each other.
As shown in Figure 1, contact the lockup state that forms entire mechanism by the circular arc feeler 32 of shifting block 3 front ends with first contact 23 on the ratchet 2, because it is smaller that the circular arc feeler 31 of shifting block 3 front ends and first contact 23 on the ratchet 2 contact relative size, when automotive seat are subjected to impacting than significantly, there is the more than situation of lock to take place, in order to guarantee the safety of locked point on the ratchet 2, just increased the length of first contact 23 on the ratchet 2, as shown in Figure 3; By shown in Figure 2, circular arc feeler 32 by shifting block 3 ends contacts the released state that forms entire mechanism with second contact 24 of ratchet 2, because it is smaller that the circular arc feeler 32 of shifting block 3 ends and second contact 24 of ratchet 2 contact relative size, so the state of not opening is arranged during on the go, in order to protect this seat angle adjustor rational releasing force is arranged, just increased the length of shifting block 3 ends, as shown in Figure 4.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
