Detailed description of the invention
Fig. 1 is according to of the present invention for buffering the longitudinal cross section of the gas support structure of inflator.
Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, foregoing end other objects of the invention, feature, side
Face and advantage will be apparent, and so that those skilled in the art can carry out according to the description.In the accompanying drawings,
For clarity, shape and size can be amplified, and will be indicated in all figures using identical appended drawing reference identical
Or similar component.In the following description, such as center, thickness, height, length, front, back, rear portion, the left side, the right, top
The words such as portion, bottom, top, lower part are to be based on the orientation or positional relationship shown in the drawings.Particularly, " height " is equivalent to from top
Portion is to the size of bottom, and " width " is equivalent to size from left to right, and " depth " is equivalent to vertical size.These
Relative terms are to be not intended to need specifically to be orientated for convenience and usually.It is related to the term of attachment, connection etc.
(for example, " connection " and " attachment ") refer to these structures by the relationship that intermediate structure is fixed directly or indirectly to one another or is attached,
And movable or rigidly attached or relationship, unless otherwise clearly stating.
Referring to Fig.1, the gas support structure for buffering inflator includes:
Gas strut 13；
It is slidably socketed in the inflator sealing-plug 136 on gas strut 13；And
It is connected to the piston 1352 of 13 end of gas strut,
Wherein, piston 1352 is located at the underface of inflator sealing-plug 136, and inflator sealing-plug 136 includes the first sealing
1361 and second sealing 1362, the second sealing 1362 be integrally connected to the lower surface and second of the first sealing 1361
The radius of sealing 1362 less than the first sealing 1361 radius so that the first sealing 1361 and the second sealing
It is formed with sealing shoulder between 1362, is arranged with exterior seal ring 137 on the sealing shoulder.Inflator sealing-plug 136 is by shaped like rubber
Glue elastomeric material is made, and when inflator sealing-plug 136 fills in the opening of buffering inflator, the second sealing 1362 deeply buffers gas
The inside of cylinder simultaneously forms sealing with the inner sidewall of buffering inflator, and the first sealing 1361 is then covered in the opening of buffering inflator
On, to be sealed to the opening.
Further, the inner circumferential of the first sealing 1361 is formed with a circle cross section in the first interior sealing of convex shape structure
Slot is embedded with the first matched inner seal ring 139, the inner circumferential of the first inner seal ring 139 in seal groove in described first
It is contacted with the side continuous elastic of gas strut 13.First inner seal ring 139 is also made of elastic material, and the first inner seal ring
139 hardness is slightly less than inflator sealing-plug 136, soft or hard different using seal groove in the first of this convex shape structure and two kinds
Elastic material can make the first inner seal ring 139 be embedded in first in seal groove by stabilization, and in first that the material is soft
Sealing ring 139 is while keeping leakproofness with gas strut 13, moreover it is possible to reduce the extruding force that gas strut 13 is subject to, improve gas strut
13 durability.
Further, the inner circumferential of the second sealing 1362 is formed with the second seal groove, and second seal groove is located at described
In first immediately below seal groove, be embedded with the second sealing ring 138 in second seal groove, the inner circumferential of the second sealing ring 138 with
The side continuous elastic of gas strut 13 contacts.Second sealing ring 138 further improves between gas strut 13 and inflator sealing-plug 136
Leakproofness.
Referring again to Fig. 1, the inner circumferential of the second sealing 1362 is embedded with rigid seal bushing 1371, rigid seal bushing
1371 inner circumferential and the side of gas strut 13 are kept in contact.Since inflator sealing-plug 136 has certain height, elastic material system
At inflator sealing-plug 136 and rigid material made of contact area is big between gas strut 13, frictional force is big, be easy to cause gas strut
13 reciprocatingly slide unsmooth in inflator sealing-plug 136, and friction is small between rigid material, is conducive to improve gas strut 13
The smooth degree to reciprocatingly slide.
Further, the end of gas strut 13 is connected with plunger piston connector 135, the outer Monday of piston connector 135
Be formed with to body formula the carrier 1351 that a circle extends horizontally outward, piston 1352 be sheathed on piston connector 135 at least and by
Carrier 1351 is accepted.
Further, the surface of piston 1352, be bolted with tightening nut 1363, tightening nut on piston connector 135
1363 and piston 1352 upper surface and carrier 1351 and the lower surface of piston 1352 between be equipped with spring leaf 1354.To make
Piston 1352 is tightened nut 1363 and screws when being installed on piston connector 135, the offer that spring leaf 1354 can continue
Pretightning force straight up, so that piston 1352 is mounted more to fasten.
Further, the periphery of piston 1352 offers at least one circle shallow slot 1353, so that the periphery of piston 1352
It is formed at least two panels sealing lip.The design of multiple sealing lips, so that piston 1352 can reduce while guaranteeing leakproofness
The contact area of piston 1352 and buffering cylinder inner wall, further improves the smoothness that gas strut 13 reciprocatingly slides.
Referring again to Fig. 1, the elastic core element extended along its length 134 is embedded with inside gas strut 13, elasticity
The end of core 134 is in end that is coniform and not protruding from gas strut 13, is formed on piston connector 135 and flexible core
The apical lateral of the groove that the end of body 134 matches, piston connector 135 is screwed in from the end of gas strut 13, so that
Piston connector 135 is by the end bolt of the groove and elastic core element 135, and the apical lateral of piston connector 135
With 13 bolt of gas strut.Using the connection type of this inside and outside bolt connection type, on the one hand improves piston connector 135 and gas supports
On the other hand the stability that bar 13 connects also improves the convenience of the dismounting of piston connector 135.
Number of devices and treatment scale described herein are for simplifying explanation of the invention.To application of the invention,
Modifications and variations will be readily apparent to persons skilled in the art.
Although the embodiments of the present invention have been disclosed as above, but it is not limited in listed fortune in specification and embodiments
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily real
Now other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is not limited to
