Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the automobile external window wiper bar that a kind of cost is low, production technology is simple, row yielding is high is provided.
The purpose of this utility model is achieved in that a kind of automobile external window wiper bar, it comprises metallic framework, press strip, bound edge and flanging, described metallic framework, its outward appearance is strip, section is and is similar to inverted " U " type structure, and metallic framework is coated with bound edge near the one side of something and the top outer of glass for vehicle window, and metallic framework is equipped with press strip away from the half of inboard and inside top of glass for vehicle window, metallic framework is shaped on flanging away from the edge of glass for vehicle window one side of something, it is characterized in that:
Described bound edge is inboard contact with the car door panel beating locate to be shaped on burr,
Described press strip is made arc, arc press strip arc towards glass for vehicle window, and arc press strip is provided with hangnail near bound edge burr side, forms folder mouthful between this hangnail and the burr.
The utility model automobile external window wiper bar, described arc press strip all adopts hard material to make, so that intensity and pressure to be provided, also the hangnail part can be made of soft material, to improve the friction force between itself and the car door panel beating, remainder then adopts hard material to make, to guarantee its intensity and pressure.
The utility model adopts the burr of bound edge and the hangnail of arc press strip that friction force is provided, and adopts the arch press strip of secondary installing that intensity and pressure are provided, thereby reaches required contact engaging and separating force.Compare with existing wiper bar, the utlity model has following advantage and effect:
1, simplifies the compound section of extruding, can reduce the compound difficulty of extruding, improved the row yielding of product;
2, adopt the arch press strip of arch hard material that better lateral pressure can be provided, guarantee the intensity and the contact engaging and separating force of product;
3, press strip has adopted hard material, under the condition that guarantees enough contact engaging and separating forces, has significantly reduced the use amount of material, has reduced cost.
The specific embodiment
Referring to Fig. 1, the utility model automobile external window wiper bar mainly is made up of metallic framework 1, arc press strip 2, bound edge 3, car door panel beating (part) 4 and flanging 5.
Described metallic framework 1 provides the intensity of product, and its outward appearance is strip, and its section is and is similar to inverted " U " type structure.Metallic framework 1 is coated with bound edge 3 near the one side of something and the top outer of glass for vehicle window, and the side that bound edge contacts with wind glass is shaped on flocking burr 3.1, and flocking burr 3.1 work keep off the rain sealing and water guide effect with glass contact; Bound edge 3 is inboard contact with the car door panel beating locate to be shaped on burr 3.2, burr mainly provides the friction force of sealing band and panel beating.Metallic framework 1 is shaped on flanging 5 away from the edge of glass for vehicle window one side of something, guarantees the contact seal when rain bar and car door panel beating, and is dustproof, waterproof.Metallic framework 1 is equipped with arc press strip 2 away from the half of inboard and inside top of glass for vehicle window, lateral pressure after product is installed is provided, arc press strip 2 arc towards glass for vehicle window, press strip 2 is made arc, arc press strip 2 arc towards glass for vehicle window, arc press strip 2 is provided with hangnail 2.1 near bound edge burr 3.2 sides, forms the folder mouth between this hangnail 2.1 and the burr 3.2.Wiper bar presss from both sides mouth thus and is installed on the car door panel beating.Arc press strip all adopts hard material to make, and also the hangnail part can be made of soft material, and remainder then adopts hard material to make.
