Embodiment

The embodiment of the application is described in detail below in conjunction with the accompanying drawings.

Refer to shown in Fig. 1 to Fig. 4, Wiper assembly 100 includes bearing 1, pivot 2 and shield 3.Bearing 1 has the axially opposing end 12 of first end 11 and second, sets stop section 133 in the outer peripheral face 13 close to first end 11, two stop sections 133 are axisymmetrically arranged.Outer peripheral face 13 includes the first peripheral section 131 and the second peripheral section 132, and the external diameter of the first peripheral section 131 is less than the external diameter of the second peripheral section 132, and the peripheral section 132 of the first peripheral section 131 to the second is closer to first end 11.Bearing 1 is fixed to support 4 with grafting, welding or the mode such as integrally formed, and support 4 is used to be fixed to vehicle, for example, fixed support 4 through the mounting hole 41 on support by fasteners such as bolts, thus, bearing 1 is supported by support 4.

Pivot 2 can be pivotally mounted in bearing 1, and it has axially opposing two ends, wherein, one end is the joint 21 extended out from the first end 11 of bearing 1, for installing wiper（It is not shown）；The other end extends out from the second end 12 of bearing 1, is connected to rocking bar 46.It is pivotally attached to the drive rocker 46 of connecting rod 47 of rocking bar 46 and and then drives wiper reciprocally swinging in the reciprocating rotation in bearing 1 of pivot 2, the drive installation of pivot 2 to joint 21.

Shield 3 includes collecting tank 31, collecting tank 31 be a collection liquid senior middle school of surrounding between low cell body, and the liquid of collection is discharged to by two liquid outlets 33,34 of basic relative direction will not pollute the position of the part such as support 4, rocking bar 46 or connecting rod 47.Cylinder portion 32 is set in the middle part of collecting tank 31, the edge of collecting tank 31 is left in cylinder portion 32, and away from two liquid outlets 33,34.Two guide portions 36,38 are each extended between cylinder portion 32 and two liquid outlets 33,34.In the state of Wiper assembly 100 is installed to vehicle body, the collecting tank 31 at cylinder portion 32 is higher than the collecting tank 31 at liquid outlet 33,34, so that the liquid at cylinder portion 32 smoothly flows to liquid outlet 33,34.

Insertion cylinder portion 32 has endoporus 320 vertically, and cylinder portion 32, which is set, has fastener 325 on elastic arm 324, elastic arm 324.Please emphasis with reference to refering to shown in Fig. 3, during mounting strap 3, endoporus 320 is installed on the outer peripheral face 13 of bearing 1 by edge from first end 11 to the direction at the second end 12, install by stop section 133 when fastener 325 by the extruding radial of stop section 133 move and make the elastic deformation of elastic arm 324, when shield 3 is installed in place elastic arm 324 release elastic deformation and make fastener 325 be resisted against stop section 133 close to the second end 12 side.In the embodiment of diagram, shield 3 is fixed in the way of not contacting support 4.

In the embodiment according to the application, cylinder portion 32 and collecting tank 31 are integrally formed using plastics.The opening of collecting tank 31 can easily be molded manufacture towards basically identical with the axial direction in cylinder portion 32 with simple mould, it is not necessary to the loose piece mechanism of complexity is set on mould.

Endoporus 320 includes the first inner circumferential section 321 and the second inner circumferential section 322, the internal diameter of first inner circumferential section 321 is less than the internal diameter of the second inner circumferential section 322 and less than the external diameter of the second peripheral section 132, first inner circumferential section 321 coordinates the first peripheral section 131, and the second inner circumferential section 322 coordinates the second peripheral section 132.That is, first inner circumferential section 321 is identical with the basic size of the first peripheral section 131, and the second inner circumferential section 322 is identical with the basic size of the second peripheral section 132, one of ordinary skill in the art can determine the tightness combined using the suitable margin of tolerance.For example, when making shield 3 using the material with preferable elastic deformability, can be with gap fit tolerance, so that easily installing both；Can also be using interference fit, so that endoporus 320 is combined closely with outer peripheral face 13, with good sealing property between the two, and reduction produces noise because of vibration.Cylinder portion 32 sets the breach 326 for radially linking up endoporus 320, and elastic arm 324 is arranged in breach 326.That is, breach 326 provides the space expanded radially outward from endoporus 320, so that elastic arm 324 wherein can be freely radially movable.Feasibly, breach 326 is through the first inner circumferential section 321 and partially across the second inner circumferential section 322, and the near-end of elastic arm 324 is integrally connected to the second inner circumferential section 322, and the distal end of elastic arm 324 sets fastener 325.The width of breach 326（Circumferential size）Much smaller than the radius of endoporus 320, the length of breach 326（The size of axial direction）Permission sets sufficiently long elastic arm 324 in breach 326.Further, since the second inner circumferential section 322 that at least part is not passed through by breach 326 coordinates with the second peripheral section 132, so sewage can be prevented by being leak between outer peripheral face 13 and endoporus 320.Because stop section 133 is protrusively provided in the first inner circumferential section 321 and leaves the second inner circumferential section 322, therefore in the case where the near-end of elastic arm 324 is integrally connected to the second inner circumferential section 322, the near-end that the fastener 325 arranged in pairs or groups with stop section 133 can be left to elastic arm 324 is set, and fastener 325 can easily be resisted against the nearside of stop section 133, i.e. close to the side at the second end 12, shield 3 is locked in installation site.

Set and cooperated so that outer peripheral face 13 and the relatively unrotatable location structure of endoporus 320 between outer peripheral face 13 and endoporus 320.In feasible embodiment as depicted, location structure includes being arranged at the protuberance 138 of outer peripheral face 13 and being arranged at the groove 328 of endoporus 320, and protuberance 138 is not in relation to the axial symmetry of outer peripheral face 13, and groove 328 is not in relation to the axial symmetry of endoporus 320.Therefore, if anisotropy when installing, protuberance 138 is unable to alignment indentation 328 and can not load, and can prevent the installation of anisotropy.The location structure can prevent shield 3 from being rotated relative to bearing 1 after correctly installing, and shield 3 can be firmly secured on bearing 1.

Above embodiment is merely to illustrate the application, rather than the limitation to the application, and change and modification can also be made about the those of ordinary skill of technical field.Therefore the protection domain of the application should be defined by the claims, and equivalent technical scheme should also belong to the category of the application.
