Description
Technical field
The utility model relates to a kind of unlocking structure, refers to a kind of automobile chair back unlocking structure with boosting mechanism especially.
Background technology
The size of the various operating efforts of automotive seat always is the problem that the client pays close attention to, and a suitable operating effort directly reflects the traveling comfort of seat.The size of backrest angle manual regulation operating effort also is a key factor of seat comfort.See also Fig. 1 and be a chair back regulating mechanism of prior art, backrest skeleton 1 through one be arranged at backrest rotating shaft 11 belows gas spring 2 realize the locking of the balance and backrest skeleton 1 angle of the backrest rotating shaft 11 both sides arm of forces.Existing backrest rotating shaft 11 positions are generally higher, and are buried in foaming, need open foaming and face cover when playing bolt, have a strong impact on fitting process; The face cover is easy to generate fold, influences outward appearance.Secondly, backrest skeleton 12 is height-limited and on the low side, often causes the underbraced to head, has a strong impact on the comfort level of seat.And if backrest rotating shaft 11 positions are reduced or the height of backrest skeleton 12 are improved; Will certainly increase the difference of resistance arm of power arm and backrest rotating shaft 11 bottoms on backrest rotating shaft 11 tops; And then make the required chair back releasing force of seat increase considerably, thereby can not guarantee that chair back releasing force satisfies the customer requirement that is not more than 60N.How to address the above problem is those skilled in the art's a big problem.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art; And a kind of automobile chair back unlocking structure with boosting mechanism is provided; Realized a kind of automobile chair back unlocking structure that can effectively control the releasing force of different size gas spring, had simple in structure, highly versatile, characteristics that releasing force is little with boosting mechanism.
The technical scheme that realizes above-mentioned purpose is:
A kind of automobile chair back unlocking structure with boosting mechanism of the utility model comprises
One gas spring, first end of said gas spring is articulated in the backrest skeleton, and second end of said gas spring is connected in a basin side plate, and the release push rod of said gas spring stretches out from the direction of said second end;
One release jacking block drives and is connected in a unlock button, is used to promote said release push rod;
Said unlocking structure also is provided with a spring, and said release jacking block is oppressed said release push rod through said spring.
Above-mentioned spring is a torsion spring, and said torsion spring is pressed and is located between the convexity that said release jacking block and is formed at said basin side plate.
Perhaps above-mentioned spring is extension spring, and said extension spring is drawn and is located between the convexity that said release jacking block and is formed at said seat basin side plate.
The utility model has been owing to adopted above technical scheme, makes it have following beneficial effect to be:
Through between release jacking block and convexity, establishing a spring; Release jacking block pressure is located on the release push rod of gas spring; Thereby a constant preset force that is not more than releasing force is provided can be according to actual needs for gas spring release end; Only need provide a less action force to get final product when having realized the user, increase considerably the designer to the backrest moulding, the range of choice of backrest rotating shaft position and gas spring specification the gas spring release.Have simple in structure, highly versatile, characteristics that releasing force is little.

The specific embodiment
Below in conjunction with specific embodiment the utility model is described further.
Embodiment one:
See also Fig. 2; A kind of automobile chair back unlocking structure with boosting mechanism of the utility model comprises a gas spring 2, and first end of gas spring 2 is articulated in backrest skeleton 1; Second end of gas spring 2 is connected in a basin side plate 3, and the release push rod 21 of gas spring 2 stretches out from the direction of second end; One release jacking block 32 is articulated in a basin side plate 3 and drives through rotating shaft 31 and is connected in a unlock button 5, is used to promote release push rod 21; Unlocking structure also is provided with a spring 4, and release jacking block 32 is through spring 4 compressing release push rods 21.
See also Fig. 3, Fig. 4, spring 4 is a torsion spring, and the torsion spring pressure is located at release jacking block 32 and and is formed between the convexity of basin side plate 3 33.The pressure that release push rod 21 receives is less than the releasing force of gas spring 2.
See also Fig. 6; The principle of work of gas spring 2 is following: when the cock body 23 and the push rod 22 end through holes of release push rod 21 ends do not have the gap and cooperate; Stoped oil flowing between gas spring 2 inner first cavitys 25 and second cavity 26, gas spring 2 is in lockup state.And after release push rod 21 receives a external force greater than fixing releasing force; Release push rod 21 is outstanding push rod 22 end through holes under the promotion of external force; This moment first cavity 25 and 26 conductings of second cavity; Thereby make gas spring 2 in-to-in oil between first cavity 25 and second cavity 26, to flow gas spring 2 releases.
See also Fig. 2, Fig. 7; Release jacking block 32 provides a constant preset force that is not more than releasing force to release push rod 21 under the effect of spring 4; When customer requirement during to the release of the automobile chair back, can press unlock button 5 with a less power, unlock button 5 presses down and drives plastic slide block 52 with a button contained spring 51 and moves down; Promotion connection spanner 34 drives the rotating shaft 31 that is arranged on the basin side plate 3 and rotates in the same way; The release push rod 21 of rotating shaft 31 transmission release jacking blocks 32 compressing gas springs 2, spring 4 also continues to provide to release jacking block 32 elastic force of the release push rod 21 of a compressing gas spring 2 simultaneously, makes gas spring release push rod 21 under the promotion of release jacking block 32, move forward; Gas spring 2 releases, thereby the release of the realization automobile chair back.
Embodiment two:
See also Fig. 5, the difference of a present embodiment and a last embodiment is: spring 4 also can adopt extension spring, and extension spring is drawn and is located between release jacking block 32 and protruding 33.
The utility model is through utilizing the release characteristic of gas spring 2; Between release jacking block 32 and protruding 33, establish a spring 4; Release jacking block 32 pressures are located on the release push rod 21 of gas spring 2; Thereby can the one constant preset force that is not more than releasing force is provided for gas spring 2 release ends according to the size of gas spring 2 required releasing forces, the release that only need provide a less action force can realize the automobile chair back when making the user to gas spring 2 releases can not influence gas spring 2 performances simultaneously yet.Increased considerably the designer to 1 moulding of backrest skeleton, the range of choice of backrest rotating shaft 11 positions and gas spring 2 specifications.Have simple in structure, highly versatile, characteristics that releasing force is little.
More than combine accompanying drawing embodiment that the utility model is specified, those skilled in the art can make the many variations example to the utility model according to above-mentioned explanation.Thereby some details among the embodiment should not constitute the qualification to the utility model, and the scope that the utility model will define with appended claims is as the protection domain of the utility model.
