Abstract
The invention discloses the liner that a kind of plastic inner container winds composite cylinder entirely, including liner ontology, the surface of liner ontology is equipped at intervals with several annular convex platform.The liner can be such that moment of inertia when liner stress increases by the way that annular convex platform is arranged, and to increase liner intensity, disperse the pressure of liner, can deform to avoid liner.
Description
Technical field
The present invention relates to mounted gas cylinder field, more particularly to a kind of plastic inner container winds the liner of composite cylinder entirely.
Background technology
Currently, in gas-fueled vehicles and fuel cell car, fuel is mostly stored in vehicle-mounted gas in a manner of compressed gas
In bottle.With the development of gas-fueled vehicles and fuel cell car, light-weighted demand also proposed for mounted gas cylinder.At me
State, widely used gas cylinder is mainly that steel liner gas cylinder, steel liner hoop winding gas cylinder and aluminum liner wind gas entirely at this stage
Bottle.And in the world, plastic inner container fiber winds composite cylinder fast development entirely, has become mainstream.With three of the above gas cylinder
It compares, plastic inner liner full-winding gas bottle has following several advantages：1, stress corrosion and Hydrogen Brittleness Phenomena are not will produce, is particularly suitable for
CNG and high pressure hydrogen；2, plastic inner container has excellent anti-fatigue performance, and fatigue life is up to 45000 times or more；3, corrosion-resistant
Superior performance (acid and alkali resistance corrosion), it is of less demanding to gas purity；4, shock resistance is superior (bottle elasticity is good), even if bottle
Body will not be exploded by impact dell；5, it is amenable to harsh bonfire test；6, manufacturing cost is low；7, in high-pressure hydrogen storing
Field is light-weight, more advantageous.
But plastic inner container winds the liner of composite cylinder during inflation/deflation repeatedly entirely, plastic inner container is born always
Different pressure.And plastic inner container intensity is smaller, in the case where pressure reduces, liner may deform, or even occur
Stress cracking.
Being disclosed in the information of the background technology part, it is only intended to increase understanding of the overall background of the invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or imply that the information is constituted in any form.
Invention content
The purpose of the present invention is to provide the liners that a kind of plastic inner container winds composite cylinder entirely, by increasing the strong of liner
Degree, avoids liner from deforming.
To achieve the above object, the present invention provides the liners that a kind of plastic inner container winds composite cylinder entirely, including liner
The surface of ontology, liner ontology is equipped at intervals with several annular convex platform.Inertia when can make liner stress by the way that annular convex platform is arranged
Torque increases, to increase liner intensity.
Preferably, the distance between adjacent annular boss is more than the thickness of liner, and the distance between annular convex platform need to be more than interior
Courage thickness is to avoid stress concentration.
Preferably, liner ontology includes the cylinder of straight section, and annular convex platform is molded together with cylinder.
Preferably, the outer surface of liner ontology is wrapped with winding layer, and annular convex platform is located at the inner surface of liner ontology.
Preferably, annular convex platform is located at the outer surface of liner ontology, and the outer surface equipped with annular convex platform, which winds and cures, to be had
Carbon fiber.
Preferably, the edge of annular convex platform is rounded structure, the annular convex platform and the surface of the liner ontology
Junction fillet is excessive.
Compared with prior art, the present invention has the advantages that：By between the inner surface or outer surface of liner
Every designing several annular convex platform, the structure of annular convex platform can increase the intensity of liner, to increase the non-deformability of liner,
And do not increase wall thickness, save raw material and cost.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram for the liner that plastic inner container according to the present invention winds composite cylinder entirely；
Fig. 2 is another structural schematic diagram for the liner that plastic inner container according to the present invention winds composite cylinder entirely；

Below in conjunction with the accompanying drawings, the specific implementation mode of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield range is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
Embodiment 1
As shown in Figure 1, winding the liner of composite cylinder entirely according to a kind of plastic inner container of the specific embodiment of the invention
100, including liner ontology 101, the inner surface of the liner ontology 101 be equipped at intervals with several annular convex platform 102, annular convex platform 102
Structure can increase the intensity of liner, to increase the non-deformability of liner, and do not increase wall thickness, save raw material at
This.Preferably, the distance between adjacent annular boss 102 is more than the thickness of liner 100, and the distance between annular convex platform 102 is more than
Liner thickness, to avoid stress concentration.Under normal circumstances, composite cylinder is made of liner, winding layer and metal seat valve, liner
Cylindrical, bottom end and the metal seat valve of cylindrical shape liner are tightly connected, and the other end of cylindrical shape liner is hemispherical, among it
Cylinder with one section of straight section, annular convex platform 102 are arranged in cylinder position, and preferred implementation is annular convex platform 102 and cylinder
Body is molded together, is realized by mold design, and usually, the forming method of plastic inner container can be injection molding.The present embodiment
In, inner side of liner designs annular convex platform 102, and the outer surface of liner 100 is wrapped with winding layer 103, and the main component of plastic inner container can
Think high density polyethylene (HDPE) (HDPE) or the thermoplastic resins such as nylon 6 (PA6) or nylon66 fiber (PA66).The fiber of winding layer 103
Can be one or more of fibers such as carbon fiber, glass fibre or aramid fiber, resin can be the thermosettings such as epoxy resin
Property resin or thermoplastic resin.As a kind of specific embodiment, plastic inner container is made using high density polyethylene (HDPE), is passed through
