[Technical field]

[0001] The present invention relates to a wiper blade, and more particularly to a wiper blade with a multi-segment decorative cover structure. [Background technology]

[0002] Regarding the wiper blade used on the windshield of a vehicle, the conventional wiper blade includes a squeegee and a plurality of frames that are movably connected to each other, and the squeegee is connected so as to straddle the partial frames. Since the plurality of frames of the conventional wiper blade are not all covered, there is a problem that the aesthetic appearance is impaired.

[0003] For this reason, a decorative cover is added to conventional wiper blades, and all of the aforementioned multiple frames are covered by this decorative cover, so that the decorative cover covers the multiple frames and maintains an aesthetic appearance. Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional wiper blades have a problem that the operation of the multiple frames is hindered by adding a decorative cover, as described below. The glass of a vehicle is curved, and when the squeegee rubs the glass of the vehicle, each of the frames is linked to perform a corresponding operation according to the curved surface of the glass of the vehicle. However, this original corresponding operation is hindered or limited by the full-face decorative cover, and each of the frames cannot perform its original operation, making it difficult to cleanly wipe off water droplets on the glass of the vehicle, which has been a problem.

[0005] Therefore, the present inventors believed that the above-mentioned drawbacks could be improved, and as a result of extensive research, they came to propose the present invention, which effectively improves the above-mentioned problems through rational design.

[0006] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide a wiper blade having a multi-segment decorative cover structure in which the decorative cover structure is divided into multiple sections and there are no connections between the sections, so that the decorative cover structure does not interfere with or restrict the squeegee when scrubbing the vehicle glass. [Means for solving the problem]

[0007] In order to achieve the above object, the wiper blade having a multi-split decorative cover structure of the present invention employs the following means. The wiper blade having a multi-split decorative cover structure according to the present invention comprises a frame structure including a main frame, at least two auxiliary frames, and a plurality of sub-frames, a squeegee connected to each of the sub-frames, and a decorative cover structure including a main decorative cover, at least two auxiliary decorative covers, and at least two sub-decorative covers. A middle section of each auxiliary frame is rotatably connected to both ends of the main frame, and a middle section of each sub-frame is swingably connected to both ends of each auxiliary frame, and each of the sub-frames and a part of the sub-frames are all provided with an insertion hole. The main decorative cover covers the main frame, each auxiliary decorative cover covers each auxiliary frame, and each sub-decorative cover covers a part of the sub-frames, and each auxiliary decorative cover is provided with an insertion bar that is inserted into the insertion hole of each auxiliary frame, and each sub-decorative cover is provided with an insertion bar that is inserted into the insertion hole of a part of the sub-frames. Effect of the Invention

[0008] According to the present invention, the following effects are obtained. The decorative cover structure is divided into multiple parts such as a main decorative cover, an auxiliary decorative cover, and a sub decorative cover, and there is no connection between any two of the main decorative cover, the auxiliary decorative cover, and the sub decorative cover, which has the effect of preventing the squeegee from being hindered or restricted by the decorative cover structure when rubbing against the vehicle glass.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following examples, and can be modified as desired without departing from the gist of the present invention.

[0012] The configuration of a wiper blade having a multi-segment decorative cover structure according to a first embodiment of the present invention is shown in Figures 1 to 10. The configuration of a wiper blade having a multi-segment decorative cover structure according to a second embodiment of the present invention is shown in Figure 11. The configuration of a wiper blade having a multi-segment decorative cover structure according to a third embodiment of the present invention is shown in Figure 12.

[0013] (First Example) A wiper blade (hereinafter also referred to as a "wiper") having a multi-split decorative cover structure according to a first embodiment of the present invention includes a frame structure 1, a decorative cover structure 2, and a squeegee 3. More specifically, the wiper blade further includes a plurality of connectors 4.

[0014] The frame structure 1 includes a main frame 11, at least two auxiliary frames 12, and a plurality of sub-frames 13. In this embodiment, the number of auxiliary frames 12 is two, and the number of sub-frames 13 is a multiple of four. In other embodiments not shown, when the size of the wiper blade is increased, the number of auxiliary frames 12 and sub-frames 13 is correspondingly increased. Incidentally, the main frame 11, the auxiliary frames 12, and the sub-frames 13 are all divided into a left stage, a right stage, and a middle stage connected between the left stage and the right stage (reference numerals are omitted in the drawings).

[0015] Each middle section of the auxiliary frame 12 is rotatably connected to both ends of the main frame 11. Specifically, by inserting a bolt P between the main frame 11 and the auxiliary frame 12, the auxiliary frame 12 moves like a seesaw relative to the main frame 11 with the bolt P as an axis.

[0016] The middle sections of each of the subframes 13 are swingably connected to both ends of the auxiliary frames 12, the squeegee 3 is connected to straddle each of the subframes 13, an insertion hole 17 is formed in each of the above-mentioned middle sections of each of the auxiliary frames 12, and the insertion holes 17 and the insertion points of the bolts P need to be offset from each other. Of the multiple subframes 13, the two subframes 13 connected to the two outer ends of the two auxiliary frames 12 all have insertion holes 17a formed in the above-mentioned middle sections, and the insertion holes 17a and the elongated holes 16a need to be offset from each other.

[0017] The above-mentioned swingable connection is a variety of possible connection methods, specifically, the auxiliary frame 12 and the sub-frame 13 are connected by the connector 4, and the sub-frame 13 swings relative to the auxiliary frame 12 with the connector 4 as an axis. To be more specific, the auxiliary frame 12 has a slot (long, thin hole) 16 at each end, and the sub-frame 13 has a slot 16a at the above-mentioned middle portion, and the connector 4 is inserted into the slot 16 of the auxiliary frame 12 and the slot 16a of the sub-frame 13, and the connector 4 is loosely clamped between the auxiliary frame 12 and the sub-frame 13 by the user rotating the connector 4 at an angle (e.g., 90 degrees). As shown in FIG. 4 combined with FIG. 6, the connector 4 inserted and rotated at an angle crosses the slot 16a in a cross shape.

[0018] The decorative cover structure 2 includes a main decorative cover 21, at least two auxiliary decorative covers 22, and at least two sub-decorative covers 23. The main decorative cover 21 covers the main frame 11, each of the auxiliary decorative covers 22 covers each of the auxiliary frames 12, and each of the sub-decorative covers 23 covers a portion of the multiple sub-frames 13. An insertion bar 27 is protrudingly provided on each of the auxiliary decorative covers 22, and each of the insertion bars 27 is inserted (press-fitted) so as to be tightened so as to correspond to each of the insertion holes 17 of the auxiliary frame 12. An insertion bar 27 is also protrudingly provided on each of the sub-decorative covers 23, and each of the insertion bars 27 is inserted (press-fitted) so as to be tightened so as to correspond to each of the insertion holes 17a of some of the multiple sub-frames 13. In this way, each of the decorative covers (referring to the main decorative cover 21, the auxiliary decorative cover 22, and the sub decorative cover 23, the same applies below) can be fixed to each of the frames (referring to the main frame 11, the auxiliary frame 12, and the sub frame 13, the same applies below).

[0019] Incidentally, as shown in Figures 6 and 8, the insertion bar 27 is a hollow bar so as to be able to be inserted (press-fitted) in a tightening manner, and therefore the insertion bar 27 has a hollow portion 273. Each of the insertion bars 27 protrudes from the inner wall of the auxiliary decorative cover 22 and the sub decorative cover 23, a free end 271 is formed at each protruding end of the insertion bar 27, and the hollow portion 273 has an opening formed in the free end 271. In this way, the diameter of the insertion bar 27 is elastically reduced by the hollow portion 273, and the insertion bar 27 can be inserted (press-fitted) in a tightening manner into the insertion holes 17, 17a.

[0020] In one embodiment, as shown in Fig. 4 and Fig. 9, at least one pair of ribs R is provided on the inner walls of each of the main decorative cover 21, the auxiliary decorative cover 22, and the sub decorative cover 23, and each pair of ribs R has a buckling protrusion R1. The pair of ribs R of the main decorative cover 21 is reversely fastened to the lower end of the main frame 11 by its buckling protrusion R1, the pair of ribs R of the auxiliary decorative cover 22 is reversely fastened to the lower end of the auxiliary frame 12 by its buckling protrusion R1, and the pair of ribs R of the sub decorative cover 23 is reversely fastened to the lower end 131 of the sub frame 13 by its buckling protrusion R1 (see Fig. 9). This allows each of the decorative covers to be more firmly fixed to each of the frames.

[0021] 3 and 4, a pair of bumps 18 are further provided on the bottom surface of each of the sub-frames 13, and one bump 18 is located on each of the opposing sides of the slot 16a. As a result, when the user inserts the connector 4 as described above and rotates it at an angle, the long side of the bottom (reference numeral omitted in the drawings) of the connector 4 exposed to the outside from the bottom surface of the sub-frame 13 is locked by the pair of bumps 18, and the connector 4 does not rotate easily when it is locked.

[0022] As a result, the decorative cover structure 2 is divided into a plurality of sections (including a main decorative cover 21, at least two auxiliary decorative covers 22, and at least two sub-decorative covers 23) and the sections are not connected to each other, so that the squeegee 3 connected to be straddled on each of the sub-frames 13 is not hindered or restricted by the decorative cover structure 2 when it performs different swinging movements along the curved surface of the vehicle glass. Therefore, the squeegee 3 smoothly performs different swinging movements together with each of the sub-frames 13, and the squeegee 3 smoothly elastically deforms according to the curved surface of the vehicle glass. In other words, by using the wiper blade of the present application, the squeegee 3 closely contacts the vehicle glass and slides back and forth, and all water droplets on the vehicle glass are neatly wiped off.

[0023] 5 and 7, there are gaps G between the main decorative cover 21 and each of the auxiliary decorative covers 22, and between each of the auxiliary decorative covers 22 and each of the sub decorative covers 23. When the wiper blade according to the present invention slides back and forth on the glass of the vehicle, there are gaps G between the main decorative cover 21 and each of the auxiliary decorative covers 22, and between each of the auxiliary decorative covers 22 and each of the sub decorative covers 23, so that they do not come into contact with each other and do not collide with each other to generate abnormal noises (for example, when the main decorative cover 21 and each of the auxiliary decorative covers 22 come into contact with each other, a collision noise is generated). Also, each of the gaps G is narrow, so that snow does not enter the gaps G.

[0024] (Second Example) 11 shows the structure of a wiper blade having a multi-split decorative cover structure according to a second embodiment of the present invention. The second embodiment is substantially the same as the first embodiment described above, and differs from the first embodiment in that the structure of each of the insertion bars 27 is changed.

[0025] In this embodiment, a flange 2711 is further provided on the periphery of each free end 271 of the insertion bar 27, and after the insertion bar 27 is inserted, each flange 2711 of the insertion bar 27 is reversely fastened to the bottom surface of the auxiliary frame 12 and the bottom surface of the sub-frame 13 so as to correspond to each of the insertion holes 17, 17a. This strengthens the fixation of each insertion bar 27.

[0026] (Third Example) 12 shows the configuration of a wiper blade having a multi-split decorative cover structure according to a third embodiment of the present invention. The third embodiment is substantially the same as the second embodiment described above, and differs from the second embodiment in that the structures of the respective insertion bars 27 are different.

[0027] In this embodiment, the insertion bars 27 of each of the auxiliary decorative covers 22 and each of the sub-decorative covers 23 are further provided with rod plugs 28, each of which includes a cover portion 281 and a plug portion 282, and the plug portion 282 is connected upright to the cover portion 281. Each of the plug portions 282 is inserted and fitted into the corresponding hollow portion 273 of each of the insertion bars 27, and after being inserted, expands the diameter of each of the insertion bars 27, thereby further increasing the degree of fastening between each of the insertion bars 27 and each of the insertion holes 17, 17a. Each of the cover portions 281 covers each of the free ends 271 of the insertion bars 27, and the buckling convex portion R1 is 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 sub-frame 13. This further strengthens the fixation of each of the insertion bars 27.

[0028] In summary, the wiper blade with a multi-split decorative cover structure according to the present invention achieves the intended purpose and effects and overcomes the shortcomings of the prior art.

[0029] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims.
