[0060] The detailed description and technical contents of the present invention will be described as follows with reference to the accompanying drawings. However, the accompanying drawings are only for illustrative purposes and are not intended to limit the present invention.

[0061] Please refer to Figures 1 to 4 As shown, it shows a three-dimensional appearance schematic diagram of the wiper assembly structure of the present invention, a partial three-dimensional enlarged schematic diagram in both sides, and a partial three-dimensional exploded schematic diagram. The present invention provides a wiper assembly structure 1, including a brush frame assembly 10, a rubber strip 20, a pair of springs 30, and a pair of clamp seats 40. The rubber strip 20 and the pair of springs 30 are combined on the brush frame assembly 10. In addition, the pair of clamp seats 40 are inserted at the two ends of the rubber strip 20, and clamp the rubber strip 20 and the pair of springs 30, so as to prevent the rubber strip 20 from falling off or shifting, thereby providing a stable wiper assembly structure 1.

[0062] The brush holder assembly 10 includes a main brush holder 11 and a pair of external buckle frames 12 connected to the main brush holder 11. Each external buckle frame 12 has a through slot 121 and an opening 122 connected to the through slot 121.

[0063] In one embodiment of the present invention, the brush holder assembly 10 further includes a pair of auxiliary brush holders 13 pivotally connected to the two ends of the main brush holder 11. Furthermore, the pair of auxiliary brush holders 13 are pivotally connected to a plurality of buckle arms 14. The ends of each buckle arm 14 are combined with a buckle frame 15. In more detail, the bottom sides of the main brush holder 11 and the pair of auxiliary brush holders 13 are spaced apart with a plurality of buckle frames 15, wherein the two buckle frames 15 located at the outermost sides are defined as outer buckle frames 12.

[0064] The rubber strip 20 extends along the main brush frame 10 to the outside of the two outer buckle frames 12. The rubber strip 20 includes a penetration portion 21 and a scraping portion 22 connected to the penetration portion 21. The penetration portion 21 is inserted into the through slots 121 of the pair of outer buckle frames 12. The penetration portion 21 includes a center column 211 and first slots 212 respectively located on both sides of the center column 211. The scraping portion 22 protrudes out of the opening 122.

[0065] The spring pieces 30 are metal spring pieces. The pair of spring pieces 30 extend along the rubber strip 20 and are respectively inserted into the first slots 212 on both sides of the center column 211. In addition, buckle holes 31 are respectively provided at both ends of each spring piece 30.

[0066] Furthermore, the clamping seat 40 is a metal piece. The pair of clamping seats 40 are fixed to the two ends of the rubber strip 20. The structure of the clamping seat 40 is described in more detail as follows.

[0067] Please refer to the other Figures 5 and 6, which shows a three-dimensional schematic diagram of the clamp seat of the present invention from both sides. Each clamp seat 40 includes a pair of connected clamp plates 41, and the pair of clamp plates 41 are provided with horizontally protruding thorns 411 on opposite sides. In addition, a notch 410 is provided on one side of each clamp plate 41, and each clamp plate 41 is provided with a stopper 412 that can buckle against the buckle hole 31 of each spring sheet 30 (see also Figure 8 The blocking portion 412 is a protruding piece, and extends obliquely from the surface of the clamping plate 41 toward the direction of the elastic piece 30 .

[0068] Accordingly, the pair of clamping plates 41 extend from one end of the rubber strip 20 into the first slots 212 on both sides of the center column 211 and abut against the pair of spring sheets 30, and the protrusions 411 of each clamping plate 41 penetrate into the center column 211. In addition, each of the external buckle frames 12 is buckled on the notches 410 of each of the clamping plates 41 (see also Figure 8 ).

[0069] Specifically, the clamp seat 40 includes a pair of connected clamping plates 41, 41', a baffle plate 42 vertically connected to the pair of clamping plates 41, 41', and a pair of side plates 43. The baffle plate 42 is connected to one end of the pair of clamping plates 41, 41'. The pair of side plates 43 are located at two opposite outer sides of the pair of clamping plates 41, 41'. In addition, one clamping plate 41 of the clamp seat 40 is provided with a spur 411 and a stopper 412. The other clamping plate 41' of the clamp seat 40 is provided with a spur 411' and a stopper 412'.

[0070] Here, the clamping plate 41 of the clamping seat 40 is used for explanation. The clamping plate 41 is provided with a recess 413 on one side of the protrusion 411 and close to the protrusion 411' of the other clamping plate 41'. In addition, a hook 414 is formed at the end of the clamping plate 41, and the hook 414 is adjacent to the notch 410. The provision of the hook 414 can facilitate the insertion of the clamping plate 41 into the rubber strip 20, thereby increasing the convenience of assembly.

[0071] Furthermore, the clamping seat 40 further includes a pair of buckle plates 44 disposed perpendicular to the baffle plate 42. The side plate 43 is provided with a buckle groove 430. One end of the buckle plate 44 is connected to the baffle plate 42, and the other end is locked in the buckle groove 430. In this embodiment, each buckle plate 44 is an L-shaped plate.

[0072] It should be noted that the baffle 42 can prevent the rubber strip 20 from being excessively penetrated during the installation of the clamp 40. In addition, the baffle 42 can block one side of the rubber strip 20 and the pair of spring sheets 30 to prevent the rubber strip 20 and the pair of spring sheets 30 from shifting and being out of position (see also Figure 3). In addition, the buckle plate 44 is used to position the side plate 43 to prevent the side plate 43 from shifting when impacted by external force, thereby preventing the rubber strip 20 from detaching.

[0073] Please refer to Figure 7 and Figure 8 The wiper assembly structure 1 of the present invention is shown in FIG. 1 , which shows a combined cross-sectional view of both sides of the wiper assembly structure. The wiper assembly structure 1 of the present invention positions the rubber strip 20 by combining the pair of clamps 40 at the two ends of the rubber strip 20 so that the rubber strip 20 is more firmly combined with the brush frame assembly 10 .

[0074] Furthermore, the rubber strip 20 passes through the buckle frame 15 of each buckle arm 14 and extends to the outside of the two outer buckle frames 12 (see also Figure 1 ). The spring sheet 30 is inserted into the first slot 212 of the rubber strip 20. Moreover, the clamping seat 40 extends from the end of the rubber strip 20 into the first slot 212 through the clamping plate 41 and abuts against the pair of spring sheets 30. One side of the spring sheet 30 abuts against the middle column 211 of the rubber strip 20, and the other side abuts against the outer buckle frame 12.

[0075] Furthermore, the insertion portion 21 of the rubber strip 20 of the present invention further includes second slots 213 located on both sides of the center column 211. The second slots 213 are located between the first slots 212 and the scraping portion 22. After the clamping plate 41 of the clamping seat 40 penetrates the first slot 212 of the rubber strip 20, each of the buckle plates 44 is located in the second slots 213 (see FIG. Figure 7 ).

[0076] It should be noted that, when the clamp seat 40 is inserted into the first slot 212, the spurs 411 of each clamp plate 41 penetrate into the center column 211. At this time, the center column 211 is squeezed by the spurs 411 and part of the material moves into the recess 413 located at the rear side of the spurs 411 (see FIG. Figure 8 The recess 413 is provided to facilitate the insertion of the first slot 212 when the clamping base 40 is installed.

[0077] It should also be noted that the clamping plate 41 has an elastic restoring force. The clamping plate 41 is elastically pressed by each of the outer buckle frames 12 at the hooks 414, and is positioned on the notch 410 by the elastic restoring force after passing through, so that the outer buckle frame 12 clamps the clamping plate 41 and ensures that the rubber strip 20 does not fall out of position.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Other equivalent changes that apply the patent spirit of the present invention should all fall within the patent scope of the present invention.
