Above-mentioned task solves by a kind of like this Wiper arm according to the present invention: this Wiper arm has at least one spring element, and this spring element can be connected with a wiper shaft of wiper device by a retaining element.According to the present invention, spring element constitutes with leaf spring, this spring element is essentially elongated structure, and have a hole on an end of its longitudinal extension part, retaining element passes this hole, and retaining element is connected with spring element, wherein the free end of this spring element deviates from mutually with that end that is provided with retaining element, spring element is connected with a linkage part at this free end, and wherein linkage part so constitutes, and makes this linkage part partly hide described leaf spring.
This Wiper arm according to the present invention has following advantage, and promptly the spring element that constitutes with leaf spring does not have a fixed part that separates, and this leaf spring has a through hole, and a retaining element passes this through hole.Just only need less parts according to Wiper arm of the present invention like this, thus can life-saving and cost saving significantly.
According to hereinafter described measure, technique scheme also has following improvement project and perfect scheme with advantage.
What have advantage especially is, retaining element has a convex shoulder, and described spring element is supported on this convex shoulder, so that spring element firmly is bearing on the retaining element.
What have advantage in addition is that described retaining element and spring element riveted joint, pressing mold or welding are because this mode can guarantee the secure between retaining element and the spring element.
In the few especially embodiment of a kind of expense, retaining element is preferably diecasting, particularly is made of zinc or aluminium diecasting.
A firm especially embodiment preferably reaches like this, and promptly retaining element is made in the forging mode, and particularly mould forges.
An anti-twist mechanism preferably is set, produces moment of torsion transmission from the retaining element to the spring element with this.
One simple and expense is few and embodiment preferred in, described anti-twist mechanism constitutes with polygonal hole, particularly hexagonal hole.

Fig. 2 shows an end according to spring element of the present invention with birds-eye view,
Fig. 3 a and 3b illustrate a birds-eye view according to the retaining element of Wiper arm of the present invention, and the section drawing that passes this retaining element,
Fig. 4 a and 4b illustrate according to a spring element of Wiper arm of the present invention and the section drawing of a retaining element, and
Fig. 5 illustrates a kind of modification according to Wiper arm of the present invention.
The specific embodiment
Fig. 1 shows one according to the Wiper arm 10 with a Wiper blade 12 of the present invention with transparent view, and this Wiper arm is used for the automobile water wiper device.Wiper blade 12 does not have link rod, in fact only has a rain brush lip 14 and a spring 16 of being made by a kind of elastomeric material, and this spring 16 is connected with rain brush lip 14.Wiper arm 10 comprises the leaf spring of a rectangular structure in fact as spring element 18, and a retaining element 20, and this retaining element 20 is placed in an end place of the longitudinal extension part of spring element 18.Spring element 18 at the other end 24 places of its longitudinal extension part with Wiper blade 12, particularly be connected with the spring 16 of Wiper blade 12.
Fig. 2 shows the details of an end 22 of leaf spring 18 with a birds-eye view.This end 22 of this spring element 18 has a hole 26, and this hole 26 constitutes with hexagon.Be essentially rectangular spring element 18 and sentence semicircle closure at its this end 22 in birds-eye view, the center 30 of its mesopore 26 is positioned at the circle centre position of semicircle 28.
Fig. 3 a shows details according to the retaining element 20 of Wiper arm 10 of the present invention with a birds-eye view.This retaining element 20 is essentially circular configuration in birds-eye view, and heart place has a boring 32 therein, and this boring 32 is used to hold the wiper shaft of wiper device.The position 35 of retaining element 20 on one sentenced hexagon and constituted, and the position above this is corresponding to the hole 26 of spring element 18 (Fig. 2), and the hole 26 by leaf spring 18 and this hexagon 34 have reached and prevented to reverse like this.Retaining element 20 is fixed in the spring element 18 antitorquely thus.
Fig. 3 b shows retaining element 20 with a section drawing.Position 36 below one is connected with the top position 35 with hexagon 34, and the position 36 below this is essentially circular configuration.Top position with hexagon 34 and following position 36 are passed in boring 32, and this boring 32 has the wiper shaft that a circular conical surface 38 is used for fixing wiper device.
Fig. 4 a shows retaining element 20 with section drawing and the state that installs of the spring element 18 that constitutes with leaf spring.Position 36 in birds-eye view below circular has a diameter bigger than hexagon 34, therefore hexagon 34 and below position 36 between a convex shoulder 40 is arranged, described spring element 18 reclines and is supported on this convex shoulder 40.The hexagon 34 of retaining element 20 passes completely through the hole 26 of spring element 18, and on the side of following position 36 or convex shoulder 40 with spring element 18 weld togethers.This preferably finishes by flash butt welding or laser beam welding.
Fig. 4 b with Fig. 4 a in same section drawing show a modification of the present invention.Spring element 18 is positioned on the convex shoulder 40 at following position 36, and hexagon 34 passes completely through spring element 18 on whole length.For fixing, hexagon 34 with spring element 18 with convex shoulder 40 opposed sides on punching out or be molded into, so just formed a riveted type and connected.
Fig. 5 illustrates the another kind of modification of the Wiper arm among Fig. 1 with a partial cross section.Retaining element 20 this with foregoing figure in equally be connected with spring element 18.Spring element 18 is connected with a linkage part 42 at its free end 24 places, and this free end 24 deviates from mutually with that end 22 that is provided with retaining element 20, and a traditional Wiper blade 12 is hinged on the linkage part 42.This moment, linkage part 42 constituted like this, and promptly it partly covers leaf spring 18.A housing 46 is set in addition, and this housing 46 covers the position of a described end 22 of connecting element 20 and spring element 18.Retaining element 20 and spring element 18 are hiding fully in this way.
In a modification of the present invention, anti-twist mechanism 26,34 also can constitute other polygon arbitrarily.Similarly can among another circular embodiment at superincumbent position 35 a simple projection only be set, a corresponding grooves in the hole 26 of this projection and spring element 18 matches.Anti-in principle twist mechanism 26,34 can have non-circular shape, and for example hole 26 or described top position 35 can be ellipse.
