Abstract
The invention discloses a safety belt end piece with a flanged square hole. The safety belt end piece comprises an end piece body, one end of the end piece body is connected with a safety belt ribbon through the square hole, the other end of the end piece body is connected with a car body through a fastening bolt, and the square hole is provided with a flanging structure. The flanging structure comprises an outer turnup and an inner turnup, wherein R of the outer turnup is 2.0+/-0.1mm, R of the inner turnup is 2.5+/-0.1mm, and the height is 5.8+/-0.1mm after flanging. In a stress state, the flanging structure has little deformation, damage to the ribbon is also very little, so that the safety belt end piece plays a role in preventing the ribbon from being damaged and further protecting car passengers.
Description
Technical field
The present invention relates to a kind of vehicle safety fender guard, specifically is a kind of middleware that belt-strap is connected with auto body by bolt.
Background technology
Square hole flange safety strap dististyle cooperates with bolt through belt-strap and is connected with auto body, is not isolated damage for the protection of ribbon when stressed, to reach the purpose of protection occupant safety.Traditional safety strap dististyle is that the mounting hole edge (being dististyle body and belt-strap contact site) at the dististyle body arranges smooth plastic gasket, is connected the effect of playing the protection belt-strap with belt-strap by plastic gasket.The shortcoming of this structure is plastic gasket cost height, cooperates the long-term use in back to come off the protection DeGrain easily.
Summary of the invention
Technical matters to be solved by this invention provides a kind of square hole flange safety strap dististyle, and this dististyle not only can be saved cost, and can effectively protect belt-strap not isolated and destroy.
A kind of square hole flange safety strap dististyle of the present invention comprises the dististyle body, and described dististyle body one end links to each other with belt-strap by square hole, and the dististyle body other end links to each other with vehicle body by binding bolt, and described square hole is provided with turnup structure.
Described turnup structure is the suitable flange of circle, the transition of R angle.
Described turnup structure comprises outer side flanging and interior side flanging, and wherein outer side flanging is R2.0 ± 0.1mm, and interior side flanging is R2.5 ± 0.1mm, and the height behind the flange is 5.8 ± 0.1mm.
The present invention compared with prior art; not only reduced cost; protection ribbon effect is obvious, and ageing length, and the square hole dististyle connects the flange structure because be that circle is along flange, the transition of R angle; belt-strap has been played the effect of even stressed, a dispersive stress effect; along with the increasing gradually of belt-strap application force tension force, the turnup structure distortion is very little, and is also very little to the damage of ribbon; play the degree that the protection ribbon destroys, and then played the effect of protection automobile passenger.Compare the technology of originally protecting safe ribbon with plastic gasket, former techniques intensity test is about 20KN, and the present invention can reach 24-25KN, and intensity has improved 20-25%; Simultaneously former techniques intensity PPK is to be used for calculation process ability or be the index of process capability among the SPC in the control chart at 1.70-1.90(PPK, when referring to that the consideration process has deviation, the process performance of sampled data) about, PPK is at 2.0-2.4 for up-to-date technology intensity, and stability improves greatly.
Description of drawings
Fig. 1 is structural representation of the present invention,
Fig. 2 is the left view of Fig. 1,
Fig. 3 is the turnup structure of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, square hole flange safety strap dististyle of the present invention comprises dististyle body 4, described dististyle body 4 one ends link to each other with belt-strap 1 by square hole, dististyle body 4 other ends link to each other with vehicle body by binding bolt 3, it is characterized in that described square hole is provided with turnup structure 2.
As Fig. 3, described turnup structure 2 is the suitable flange of circle, the transition of R angle.Comprise outer side flanging and interior side flanging, wherein outer side flanging is R2.0 ± 0.1mm, and interior side flanging is R2.5 ± 0.1mm, and the height behind the flange is 5.8 ± 0.1mm
Principle of work: when binding bolt 3 and dististyle body 4 are connected that effect is stressed on the vehicle body; belt-strap 1 is simultaneously stressed to stretch out; act on circular hole dististyle connection turnup structure 2 strength stress is arranged; because turnup structure 2 is because be that circle is along flange; the transition of R angle; it is evenly stressed that belt-strap 1 has been played a protection; the effect of dispersive stress effect; increasing gradually along with belt-strap 1 application force tension force; turnup structure 2 deformation rates are very little; damage to ribbon is also very little; play the degree that the protection ribbon destroys, and then played the effect of protection automobile passenger.
Forming method of the present invention:
By twice machine-shaping; when wherein the dististyle of moulding stretching for the first time height is to 6.3mm ± 0.1mm; keep a stretch ratio; back-pressure moulding for the second time, compression dististyle height increases dististyle local density to 5.8mm ± 0.1mm; the compression material flow is to R2.0 ± 0.1mm and R2.5 ± 0.1mm; make the R angle more smooth smooth and easy, guarantee evenly to disperse drawing stress when dististyle R angle is stressed, play the effect of protection ribbon.
The concrete application approach of the present invention is a lot, and the above only is preferred implementation of the present invention, should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
