Detailed description of the invention
Describe the detailed description of the invention of the application below in conjunction with the accompanying drawings in detail.
Referring to shown in Fig. 1 to Fig. 4, Wiper assembly 100 includes bearing 1, pivot 2 and guard shield 3.Bearing 1 has the first axially opposing end 11 and the second end 12, arranges stop section 133 at the outer peripheral face 13 near the first end 11, and two stop sections 133 are arranged axisymmetrically.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 first peripheral section 131 to the second peripheral section 132 is closer to the first end 11.Bearing 1 with grafting, the mode such as weld or be integrally formed and be fixed to support 4, support 4 is used for being fixed to vehicle, such as, is fixed by support 4 through the installing hole 41 on support by securing members 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, and wherein, one end is the joint 21 that the first end 11 from bearing 1 extends out, and is used for installing wiper (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 connecting rod 47 drive rocker 46 of rocking bar 46 and and then orders about pivot 2 reciprocating rotation in bearing 1, the wiper reciprocally swinging in pivot 2 drive installation to joint 21.
Guard shield 3 includes collecting tank 31, collecting tank 31 is cell body low between a senior middle school of surrounding collecting liquid, and the liquid of collection is discharged to pollute the position of the such as parts such as support 4, rocking bar 46 or connecting rod 47 by two liquid outlets 33,34 of basic relative direction.Arrange a portion 32 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 portion 36,38 each extend between cylinder portion 32 and two liquid outlets 33,34.When 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, in order to the liquid at cylinder portion 32 flows to liquid outlet 33,34 smoothly.
The most through cylinder portion 32 has endoporus 320, and cylinder portion 32 arranges elastic arm 324, and elastic arm 324 has fastener 325.Please combine refering to shown in Fig. 3 by emphasis, during mounting strap 3, along from the first end 11 to the direction of the second end 12, endoporus 320 being installed to the outer peripheral face 13 of bearing 1, when installing through stop section 133, fastener 325 is moved by stop section 133 extruding radial and makes elastic arm 324 elastic deformation, and when guard shield 3 is installed and put in place, elastic arm 324 discharges elastic deformation and makes fastener 325 be resisted against the side near the second end 12 of stop section 133.In the detailed description of the invention of diagram, guard shield 3 is fixed in the way of not contacting support 4.
According in the detailed description of the invention of the application, plastics are used to be integrally formed a portion 32 and collecting tank 31.The most basically identical towards with cylinder portion 32 of the opening of collecting tank 31, can easily be molded manufacture with simple mould, it is not necessary to arrange the loose piece mechanism of complexity on mould.
Endoporus 320 includes the first inner circumferential section 321 and the second inner circumferential section 322, the internal diameter of the first inner circumferential section 321 internal diameter less than the second inner circumferential section 322 and the external diameter less than the second peripheral section 132, first inner circumferential section 321 coordinates the first peripheral section 131, the second inner circumferential section 322 to coordinate 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, those of ordinary skill in the art can use the suitable margin of tolerance to determine the tightness combined.Such as, when using the material with preferable elastic deformability to make guard shield 3, can be with matched in clearance tolerance, so that easily install both；Interference fit can also be used, so that endoporus 320 is combined closely with outer peripheral face 13, there is good sealing property between the two, and reduce and produce noise because of vibration.Cylinder portion 32 arranges the breach 326 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, wherein can be the most radially movable for elastic arm 324.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 far-end of elastic arm 324 arranges fastener 325.The width (size of circumference) of breach 326 is much smaller than the radius of endoporus 320, and the length (axial size) of breach 326 allows to arrange sufficiently long elastic arm 324 in breach 326.Further, since the second inner circumferential section 322 that at least part is not passed by breach 326 coordinates with the second peripheral section 132, leak into so can prevent sewage from passing through between outer peripheral face 13 and endoporus 320.Owing to 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 of elastic arm 324 near-end 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 leave elastic arm 324 is arranged, and fastener 325 can easily be resisted against the nearside of stop section 133, i.e. near the side of the second end 12, guard shield 3 is locked in installation site.
Arrange between outer peripheral face 13 and endoporus 320 and cooperate so that outer peripheral face 13 and endoporus 320 can not location structures in relative rotation.In feasible detailed description of the invention as depicted, location structure includes the protuberance 138 being arranged at outer peripheral face 13 and is 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 install time anisotropy, then protuberance 138 can not alignment indentation 328 and cannot load, the installation of anisotropy can be prevented.After correctly installing, this location structure can stop guard shield 3 to rotate relative to bearing 1, and guard shield 3 can be firmly secured on bearing 1.
Above detailed description of the invention is merely to illustrate the application, rather than the restriction to the application, the those of ordinary skill about technical field can also make change and modification.Therefore the protection domain of the application should be defined by the claims, and the technical scheme of equivalent also should belong to the category of the application.
