Abstract
The invention discloses a single end strip of an automobile safety belt and a preparation method thereof, wherein the single end strip comprises a single end strip body; the single end strip body is provided with a mesh belt connection part and a fixed connection part; the center of the mesh belt connection part is provided with an inner ring; the mesh belt of the safety belt passes through the inner ring, so that the connection with the single end strip body is realized; and a turnup is arranged along the edge of the inner ring. The preparation method comprises the following steps of: manufacturing the single end strip body according to standard material quality and specification, adopting a first stamping die to form the inner ring and the turnup in a punch forming way, and adopting a second stamping die to form finished products in a reverse punching way. The turnup structure is adopted for the connection between the single end strip provided by the invention and the mesh belt of the safety belt; an R angle transition is adopted for a turnup contact face; the contact face is round and smooth, so that the mesh belt of the safety belt is evenly stressed; and moreover, the stress can be dispersed, and the safety effect is promoted remarkably. In addition, with the adoption of raw materials for punching and forming, no plastic pieces are necessarily adopted; and therefore, not only is the material cost decreased, but also the procedure is reduced and the manufacturing cost is decreased.
Description
Technical field
The present invention relates to the particularly safety guard on the car of automobile, single-ended of specifically adopting on a kind of safety strap.
Background technology
Car belt is a kind of fender guard that is installed on the automobile, is used for when sudden stop or vehicle body are subject to clashing driver and crew's health firmly being fettered on the seat, and it is preserved from.The speed of modern automobile is very fast, in case bump, the vehicle body stop motion, and passenger's body, may crash Windshield and fly out outside window forward when serious in Che Nei and vehicle body strikes because inertia can move forward.Similarly injury occurs when preventing from colliding, and public security department requires small-sized bus man and front-seat passenger to use of seat belts, so that during accident, safety strap prevents secondary injury to the effect that the people plays buffering.
Automobile safety belt device mainly comprises the drawing and pulling type belt-strap, and an end of belt-strap connects single-ended, and single-ended be fixed on the vehicle body by binding bolt.Single-ended of traditional safety strap is with metal single-ended body inner ring edge sleeving plastic liner, and plastic gasket and belt-strap directly contact and realize connecting; The shape of plastic gasket is directly corresponding with the interior loop-shaped of single-ended body, because the frequency of utilization of safety strap is very high, in the long-term use procedure, belt-strap and plastic gasket often rub, and the contact surface of plastic gasket and belt-strap is less, plastic gasket does not consider that fully loading characteristic designs suitable contact surface, cause whole bearing surface each point discontinuity, and the friction drag of plastic gasket is larger, many factors so that belt-strap in use abrasion loss is larger, under the extreme case even breaking releasing, affected its reliability, the plastic gasket cost is also higher in addition, owing to relate to the combination of bi-material, not only operation is complicated, and manufacturing cost has also risen.
Summary of the invention
Technical matters to be solved by this invention provides single-ended of better car belt of a kind of safe reliability and preparation method thereof, this single-ended area of contact with belt-strap is large, stressed even, friction force is little, the wearing and tearing of belt-strap have been reduced, and cost has promoted economic benefit.
Single-ended of a kind of car belt of the present invention, it comprises single-ended body, this single-ended body has a ribbon connecting portion that is connected with belt-strap, and one be fixed on captive joint section on the vehicle body by binding bolt, ribbon connecting portion center is provided with an inner ring, belt-strap passes this inner ring and realizes and being connected of single-ended body, and is provided with flange one along described inner ring edge.
As improvement, described flange comprises the arc surface that contacts with belt-strap, and the inclined-plane that is positioned at the arc surface dorsal part.Wherein arc surface R angle value is between R1.5-3.0mm, and being preferably this arc surface R angle leading portion cambered surface is R1.7mm, and the back segment cambered surface is R2.5mm.The angle value of inclined-plane and inner ring axis is at 30 degree ± 3 degree.The flange height value is at 1.50-2.50mm.
In addition, the invention also discloses the preparation method of single-ended of this car belt, it may further comprise the steps:
1) make single-ended body according to Standard and specification,
2) adopt the first diel punch forming to form inner ring and flange thereof, flange top to the height of single-ended body another side is 5.5mm at this moment, and keeps a stretch ratio,
3) adopt the reverse punch steps 2 of the second diel) form inner ring and flange thereof, making flange top to the height of single-ended body another side is 5.0mm, and to make flange arc surface R angle be in the leading portion cambered surface be R1.7mm, the back segment cambered surface is R2.5mm.
The present invention protects safe ribbon to compare with existing with plastic gasket, because single-ended and belt-strap junction employing flange structure, the flange contact surface adopts R angle transition; contact surface is smoother; so that the belt-strap uniform stressed, and can dispersive stress, safe effect significantly promotes.During work, in case producing, impacts by vehicle, even belt-strap application force and tension force strengthen suddenly; single-ended connection flange structural change rate is still very little; damage to ribbon is also very little, has played the effect of protection ribbon, and then has played the effect of protection automobile passenger.Compared to existing technology, after measured, prior art intensity is about 20KN, the present invention can reach 22.5-23KN,, intensity has improved about 15%, prior art intensity PPK is about 1.70-1.90 simultaneously, and intensity PPK of the present invention is at 2.1-2.5, and visible stability is greatly improved.In addition, the present invention adopts the raw MAT'L punch forming, need not to adopt Plastic Parts, has not only reduced material cost, and has reduced operation, has lowered manufacturing cost.
