Please in conjunction with illustrated in figures 1 and 2, it is front view and the top view of the plastic backstay 10 of integral type in the present embodiment, the plastic backstay 10 of described integral type comprises: locate rod member 11, be positioned at the stop bit crosspiece 13 of locating the rod member tail end, an and flexible buffer piece 12 that is positioned at dovetail groove on the stop bit crosspiece 13, it utilizes secondary injection molding to be embedded on the described stop bit crosspiece 13, firmly becomes one with location rod member 11.Described flexible buffer piece 12 is elastic block rubber.
Described location rod member 11 is designed to circle nest formula move contrail fitting wire shaped structure 14, and inside is embedded with high-strength steel core during its moulding, generally speaking, be the overload that the satisfies locator requirement of opening the door, the plastic backstay 10 of described integral type is coated with the PA66(polyamide for skin), be self-lubricating abrasion-proof material, inner pre-buried carrying out the steel core processed of surface anticorrosion select the QTE420TM high strength steel.
The plastic backstay 10 of integral type is assembled in the cantilevered door prop 100, with localiser box assembly 20 coordinated, finish the opening/closing door of vehicle limit function, please in conjunction with shown in Figure 3, it is a kind of structure chart of cantilevered door prop 100, described cantilevered door prop 100 comprises: an end is fixed on the bearing (not shown) on the car body, the other end is fixed on the localiser box assembly 20 on the car door inner chamber installed surface 26, and the plastic backstay 10 of the integral type of passing localiser box assembly 20, and housing 21 inside of this localiser box assembly 20 are provided with limiting component, comprise: fat slide block 40 is mended in the location, and elastomeric element, for example is loading spring 30.Described bearing is fastened on the vehicle body by an erection bolt (not shown), and described localiser box assembly 20 is assemblied in the installed surface 26 of car door inner chamber by one group of screw 27 of riveting box on cover plate 24.
In the time of opening/closing door of vehicle, localiser box assembly 20 is done relative motion with the plastic backstay 10 of integral type, be location rod member 11 sliding-contacts that fat slide block 40 and the plastic backstay 10 of integral type are mended in the location in the positioning box assembly 20, shape and structure according to the plastic backstay 10 of integral type, this is just so that loading spring 30 produces different elastic deformations, thereby produce different pressure, and transfer function is on described benefit fat slide block 40, apply pressure to the plastic backstay 10 of this integral type and produce the spacing power of friction, the final purpose that realizes reaching the requirement of switch gate feel and car door location.
And design improvement riveting on cover plate 24 has one group of screw 27, described housing 21 by with cover plate 24 riveteds of the one group of screw 27 that presses after, be fastened on by screw 27 on the installed surface 26 of car door inner chamber.This just is different from will get in addition one group of screw and be fastenedly connected in the prior art, improved intensity, the installation effectiveness of localiser box assembly 20, and further realized the general modularity of localiser box assembly.
Described housing 21 is the metal stamping stretching housing, considers the stamping forming requirement of housing 21, and its material is generally the DC04 cold-rolled steel sheet, and expecting thick is 1.5mm, and described cover plate 24 is generally the QStE420TM high-strength steel sheet, expects that thick is 2.0mm.
During moulding, uncovered direction at housing 21, when blanking, be reserved with riveted pawl 23 structures, in the drawing and forming process, formed preformed riveted pawl 23, rivet simultaneously pair of screws on described cover plate 24, during assembling riveted localiser box assembly 20, cover plate 24 is put into riveted pawl 22, by mould turnover riveting, become a riveted assembly, at this moment, described riveted pawl 23 is positioned at installed surface 26 sides, so that described riveted pawl 23 is clamped between installed surface 26 and the cover plate 24, realized improving the effect of riveted pawl 23 pawl riveting intensity.
When car load is installed, behind the open face of locator housing and cover plate 24 riveteds, add one deck dust-proof cushion 25 on cover plate 24, so that the installed surface 26 of itself and car door inner chamber fits, by one group of a pair of nut 28 fixing and locking of screw 27 combos, at this moment, riveted pawl 23 is between the installed surface 26 of cover plate 24 and car door inner chamber, in the time of nut 28 locking, riveted pawl 23 is held on wherein, guaranteed riveted pawl 23 can outwards not overturn and so that localiser box assembly 20 is thrown off, and then cause losing efficacy.
One group of the 20 interior settings of described riveted localiser box assembly location mend fat slide block 40 and with one group of loading spring 30 of its assembly, an end of described loading spring 30 places described grease storing chamber 42, the other end is positioned on the inwall boss 22 of described housing 21.
The grease storing chamber 42 that the combination of the described Rotary-table that connects and infundibular body consists of is used for placing loading spring 30 and storing lubricating grease.General, the material that fat slide block 40 is mended in described location is POM (polyformaldehyde).Grease storing chamber 42 internal storage that fat slide block 40 is mended in the location have quantitative lubricating grease, as can be known be, the dust tightness of localiser box assembly 20 is very important, otherwise through use after a while, enter dust in the localiser box assembly 20, the lubricity of grease reduces, door prop 100 just abnormal sound may occur, the phenomenons such as movement parts wearing and tearing, so that reduce in its sense organ comfortableness and application life, it is a riveted closing element that this use new design adopts localiser box assembly 20, be provided with dust-proof cushion 25 on the cover plate 24, after installing, door prop 100 can play dustproof effect, reduce dust and enter localiser box assembly 20, increased sense organ comfortableness and the application life of door prop 100.
Each time in the process of opening/closing door of vehicle, be designed with the track fitting wire shaped structure 14 of round nest formula convex matrix face on the described location rod member 11, so that loading spring 30 produces different elastic deformations, described location mend fat slide block 40 loading spring 30 under the effect of load inertia impact from described greasing hole 43 location from the described localiser box assembly 20 of trend in mend the sliding contact surface greasing of fat slide block 40 and backstay 10, thereby finish automatic makeup fat.
Cantilevered door prop 100, be combined with the plastic backstay 10 of integral type, localiser box assembly 20, and localiser box assembly 20 inner loading spring 30 and the whole day candidate fat slide blocks 40 that arrange, the reliability of round nest formula location and good sense organ comfortableness have been obtained, the in addition good fade resistance of loading spring 30, and strengthen riveted intensity localiser box assembly 20 have general modularity and high strength and end cost behavior, thereby realized preferably durability, low noise, high strength, the low-cost requirement of cantilevered door prop 100.
As mentioned above, the plastic backstay 10 of the integral type that the utility model provides, adopt the buffer stopper post forming in the integral structure of location rod member 11, simple in structure, compact, assembling and installation are convenient, highly versatile forms modularity, thereby has satisfied preferably durability, low noise, high strength, comfortable feel, the low-cost requirement of cantilevered door prop 100.
