[0056] The detailed description and technical contents of the present application are described as follows in conjunction with the accompanying drawings. However, the attached drawings are only provided for reference and illustration and are not intended to limit the present application.

[0057] The present application provides a windshield wiper with a multi-section decorative cover structure, such as Figures 1 to 10 The first embodiment is shown. Fig.11 and Fig.12 Shown are the second and third embodiments respectively.

[0058] like Figures 1 to 10 As shown, the first embodiment of the windshield wiper with a multi-section decorative cover structure (referred to as two wipers) of the present application includes: a skeleton structure 1, a decorative cover structure 2 and a wiper strip 3, and in detail also includes a plurality of connecting parts 4.

[0059] The skeleton structure 1 includes a main skeleton 11, at least two sub-skeletons 12 and a plurality of secondary skeletons 13. In this embodiment, the number of sub-skeletons 12 can be two, and the number of secondary skeletons 13 can be four. In other embodiments not shown in the drawings, if the size of the wiper is to be increased, the number of sub-skeletons 12 and secondary skeletons 13 can also be increased accordingly. It should be noted that the main skeleton 11, the sub-skeletons 12 and the secondary skeletons 13 can be divided into a left section, a right section and a middle section connected between the left section and the right section (all without component symbols).

[0060] The middle section of each sub-frame 12 is rotatably connected to the two ends of the main frame 11. Specifically, a latch P is inserted between the main frame 11 and the sub-frame 12, so that the sub-frame 12 can perform a seesaw-like motion relative to the main frame 11 with the latch P as the axis.

[0061] The middle section of each sub-frame 13 is movably connected to the two ends of each sub-frame 12, and the scraper strip 3 is connected across each sub-frame 13. The aforementioned middle section of each sub-frame 12 is provided with a plug hole 17, and the plug-in connection between the plug hole 17 and the pin P needs to be staggered with each other; among each sub-frame 13, the sub-frames 13 connected to the two opposite outer ends between the two sub-frames 12 also have a plug hole 17a in the aforementioned middle section, and the plug hole 17a and the long hole 16a need to be staggered with each other.

[0062] The aforementioned swayable connection can be various feasible connection methods, specifically, the connection member 4 is connected between the sub-frame 12 and the secondary frame 13, so that the secondary frame 13 can swing relative to the sub-frame 12 with the connection member 4 as the axis. In detail, each of the two ends of each sub-frame 12 is provided with a long hole (a long narrow hole) 16, and the aforementioned middle section of each secondary frame 13 is also provided with a long hole 16a, and the connection member 4 is inserted into the long hole 16 of the sub-frame 12 and the long hole 16a of the secondary frame 13, and the connection member 4 is loosely clamped between the sub-frame 12 and the secondary frame 13 by being rotated by the user at an angle (for example, 90 degrees), such as Figure 4 And with Figure 6 As shown, the connecting member 4 after being inserted and rotated to an angle is cross-staggered with the long hole 16a.

[0063] The decorative cover structure 2 includes a main decorative cover 21, at least two auxiliary decorative covers 22 and at least two secondary decorative covers 23. The main decorative cover 21 covers the main frame 11, each auxiliary decorative cover 22 covers each auxiliary frame 12, and each secondary decorative cover 23 covers each secondary frame 13. Among them, each auxiliary decorative cover 22 is provided with a plug-in column 27, and each plug-in column 27 is tightly plugged into the corresponding plug hole 17 of each auxiliary frame 12; each secondary decorative cover 23 is also provided with a plug-in column 27, and each plug-in column 27 is tightly plugged into the corresponding plug hole 17a of each secondary frame 13. In this way, each decorative cover (referring to: main decorative cover 21, auxiliary decorative cover 22 and secondary decorative cover 23, the same below) can be fixed to each frame (referring to: main frame 11, auxiliary frame 12 and secondary frame 13, the same below).

[0064] It should be noted that if Figure 6 and Figure 8As shown, in order to be able to be inserted tightly, the plug post 27 can be a hollow post, and the plug post 27 therefore has a hollow portion 273. Each plug post 27 protrudes from the inner wall of the auxiliary decorative cover 22 and the secondary decorative cover 23, and a free end 271 is formed at the protruding end of each plug post 27, and the hollow portion 273 forms an opening at the free end 271. In this way, the plug post 27 can use the hollow portion 273 to elastically reduce the diameter, thereby allowing the plug post 27 to be inserted tightly into the insertion hole 17, 17a.

[0065] In one embodiment, Figure 4 and Fig. 9 As shown, the inner walls of the main decorative cover 21, each of the auxiliary decorative covers 22 and each of the secondary decorative covers 23 are all provided with at least one pair of ribs R, and the pair of ribs R each have an inverted convex portion R1. The pair of ribs R of the main decorative cover 21 are inverted on the bottom edge of the main frame 11 with their inverted convex portions R1, the pair of ribs R of the auxiliary decorative cover 22 are inverted on the bottom edge of the secondary frame 12 with their inverted convex portions R1, and the pair of ribs R of the secondary decorative cover 23 are also inverted on the bottom edge 131 of the secondary frame 13 with their inverted convex portions R1 (see FIG. Fig. 9 ). Thus, each decorative cover can be more firmly fixed to each frame.

[0066] Furthermore, if Figure 3 and Figure 4 As shown, the bottom surface of each sub-frame 13 may also be provided with a pair of protrusions 18, and the pair of protrusions 18 are located at two opposite sides of the long hole 16a. Thus, when the user inserts the connecting member 4 as described above and rotates the angle, the bottom (not marked with component symbols) of the connecting member 4 exposed from the bottom surface of the sub-frame 13 will be blocked by the pair of protrusions 18, so that the connecting member 4 will not rotate easily when being blocked.

[0067] Thus, since the decorative cover structure 2 is broken into multiple sections (including: a main decorative cover 21, at least two auxiliary decorative covers 22 and at least two secondary decorative covers 23), and there is no connection between the sections, when the scraper strip 3 connected across the secondary frames 13 shakes differently in accordance with the curved surface of the automobile glass, it will not be hindered or restricted by the decorative cover structure 2, so the scraper strip 3 can smoothly shake differently together with the secondary frames 13, and then the scraper strip 3 can also smoothly elastically deform along the curved surface of the automobile glass. In other words, using the wiper of the present application will ensure that the scraper strip 3 scrapes back and forth against the automobile glass, and the water droplets on the automobile glass can be scraped away cleanly.

[0068] In addition, if Figures 5 to 7As shown, there are gaps G between the main decorative cover 21 and each auxiliary decorative cover 22, as well as between each auxiliary decorative cover 22 and each secondary decorative cover 23. Therefore, when the wiper of the present application is scraping back and forth on the automobile glass, the main decorative cover 21 and each auxiliary decorative cover 22, as well as between each auxiliary decorative cover 22 and each secondary decorative cover 23 will not contact each other due to the existence of the gaps G, and thus no collision noise will be generated (for example, the collision noise generated by the contact between the main decorative cover 21 and each auxiliary decorative cover 22 mentioned above); furthermore, each gap G is small in width, so snow will not enter the gap G.

[0069] like Fig.11 The second embodiment of the windshield wiper of the present application is shown in FIG. The second embodiment is substantially the same as the first embodiment, with the only difference being that the structure of each plug post 27 is changed.

[0070] In the second embodiment, the periphery of the free end 271 of each plug post 27 may further protrude with an undercut flange 2711, so that after insertion, the undercut flange 2711 of each plug post 27 is respectively undercut on the bottom surface of the auxiliary frame 12 and the bottom surface of the secondary frame 13 corresponding to each insertion hole 17, 17a. In this way, the fixing effect of each plug post 27 can be strengthened.

[0071] like Fig.12 The third embodiment of the windshield wiper of the present application is shown in FIG. The third embodiment is substantially the same as the second embodiment, with the only difference being the structure of each plug post 27 being different.

[0072] In the third embodiment, the plugs 27 of each auxiliary decorative cover 22 and each secondary decorative cover 23 are also provided with plungers 28, and the plungers 28 include a cover portion 281 and a plug portion 282, and the plug portion 282 is vertically connected to the cover portion 281. Each plug portion 282 is correspondingly inserted and filled in the hollow portion 273 of each plug 27, and after insertion, the diameter of each plug 27 is enlarged to further improve the tight fit between each plug 27 and each insertion hole 17, 17a. Each cover portion 281 covers the free end portion 271 of each plug 27, and enables the undercut protrusion R1 to be sandwiched between the cover portion 281 and the bottom surface of the auxiliary frame 12 and between the cover portion 281 and the bottom surface of the secondary frame 13. In this way, the fixing effect of each plug 27 can be further strengthened.

[0073] In summary, the wiper with a multi-section decorative cover structure of the present application can indeed achieve the expected purpose and effect of use, and can solve the deficiencies of the prior art.

[0074] The above is only the preferred feasible embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the description and drawings of the present application are also included in the scope of the rights of the present application and are hereby stated.
