[0055] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments to further understand the purpose, solution and efficacy of the present invention, but it is not intended to limit the scope of protection of the appended claims of the present invention.

[0056] Please refer to Figures 1 - 2 , which is the external three-dimensional view of the middle wing structure of the wiper of the present invention and Figure 1 the side view schematic diagram of the middle wing structure. As shown in the figure: The present invention provides a middle wing structure of a wiper, and the middle wing structure 10 includes: a pivoting plate 11, an outer arm 13 and a protruding portion 14. Among them, the middle wing structure 10 of the wiper is formed by the pivoting plate 11 and the outer arm 13 with a single-sided bending design.

[0057] On the pivoting plate 11, there is a pivoting portion 111, and on both sides of the pivoting portion 111, there are symmetrically arranged assembling grooves 112 for assembling the pivoting device 40 (as Figure 3 shown). One end of the pivoting portion 111 extends with a first inner arm 113, and on the first inner arm 113, there is a fixing hole 114 for providing the middle wing structure 10 to be fixed to the wing foot structure 30 (as Figure 3 shown). The other end of the pivoting portion 111 extends with a second inner arm 115 shorter than the first inner arm 113, and at one end of the second inner arm 115, there is a bending portion 12. Among them, the pivoting portion 111, the first inner arm 113 and the second inner arm 115 are arranged on the same straight line.

[0058] The outer arm 13 is formed by bending and extending from the bending portion 12. One end of the outer arm 13 has a connecting portion 131, and a connecting hole 132 is provided on the connecting portion 131. The connecting portion 132 also enables the middle wing structure 10 to be fixedly connected to the wing foot structure 30 (as Figure 3 shown).

[0059] The protruding portions 14 are respectively provided on the surfaces of the outer arm 13, the first inner arm 113, and the second inner arm 115. The protruding portions 14 strengthen the structures of the pivot plate 11 and the outer arm 13 itself, making the pivot plate 11 and the outer arm 13 not easily deformed.

[0060] It is worth mentioning that the inner angle of the bending portion 12 between the pivot plate 11 and the outer arm 13 is between 120 degrees and 180 degrees. With a single-sided bend, the elastic pressure for pressing down the wiper blade 20 (as Figure 2 shown) will not be too large. When the middle wing structure 10 is installed on the wiper structure for use, the wiper blade 20 will not be pressed down by excessive elastic pressure, reducing the friction coefficient between the wiper blade 20 and the windshield of the vehicle. In addition to improving the quality of wiping the windshield (being able to wipe cleanly), it can also reduce the damage rate of the wiper blade 20.

[0061] Please refer to Figures 3 - 4 , which is a partial enlarged side view schematic diagram of the decomposition of the wiper structure of the present invention. Figure 3 As shown in the figure: The wiper device of the present invention includes: two middle wing structures 10, a wiper blade 20, a plurality of wing foot structures 30, a plurality of pivots 40, a large wing structure 50, and a wiper cover 60.

[0062] The wiper blade 20 has a body 21. The body 21 is in a long strip shape, and a set of connecting portions 22 and a wiping strip 23 are respectively formed thereon. Grooves 24 are respectively formed on both side surfaces of the set of connecting portions 22, and the grooves 24 are used to assemble with the wing foot structure 30. In this figure, the wiper blade 20 is made of a rubber elastic material and can contact the windshield of the vehicle.

[0063] The wing foot structures 30 have an arc-shaped beam arm 31. Both ends of the beam arm 31 respectively have a claw portion 32. The claw portions 32 are assembled in the grooves 24 of the set of connecting portions 22, enabling the claw portions 32 to firmly hold the wiper blade 20. Then, a fixing member 15 passes through the fixing hole 114 and the connecting hole 132 of the middle wing structure 10, assembling the support wing structure 10 onto the beam arms 31 of the wing foot structures 30.

[0064] These connectors 40 have two seat bodies 41. There is a clamping channel 42 between the two seat bodies 41 for the two seat bodies 41 to be clamped onto the assembly groove 112 of the pivoting portion 111 of the pivoting plate 11. The two seat bodies 41 respectively have a communicating pivoting hole 43 through which the pivoting shaft 44 passes, enabling the middle wing structure 10 to be pivotally connected to the large wing structure 50.

[0065] The large wing structure 50 has a connecting through hole 51, to which a connecting device 52 is connected. The connecting device 52 can be installed on the wiper handle (not shown in the figure) of the vehicle. Symmetrically extending from both ends of the connecting through hole 51 are connecting arms 53, each of which has a perforation 54 through which the pivoting shaft 44 passes to be pivotally connected to the pivoting hole 43 of the connector 40, enabling the large wing structure 50 to be pivotally connected to the middle wing structure 10.

[0066] The wiper cover 60 has a through hole 61 for the connecting device 52 to be exposed. Extending from both ends of the through hole 61 are cover plates 62, which can cover the large wing structure 50, the middle wing structure 10, the connector 40, the wing foot structure 30 and the wiper blade 20, so as to reduce the occurrence of failures or damages to the large wing structure 50, the middle wing structure 10, the connector 40 and the wing foot structure 30 caused by the external environment.

[0067] By means of the unilateral bending design of the middle wing structure 10 of the wiper of the present invention, the situation of insufficient or excessive downward pressure of the wiper structure will not occur, or there will be no jumping during the brushing process of the wiper structure, which can greatly reduce the damage of the wiper blade 20 and extend the service life of the wiper blade 20.

[0068] In addition, since the middle wing structure 10 of the wiper of the present invention adopts a unilateral bending design, compared with the US Patent No. US11180118B2 (hereinafter referred to as the previous case), Figure 6 of the previous case discloses a secondary frame, which adopts a bilateral asymmetric bending design and includes a central pivot connection portion. At both ends of the central pivot connection portion, an outer leg and an inner leg respectively extend. Taking the central pivot connection portion as a reference, the downward bending angle of the outer leg is smaller than that of the inner leg, forming the asymmetric bending design as described above.

[0069] In addition, the asymmetric bending design of the previous case is time-consuming and laborious during production. Moreover, after being installed on the wiper handle of an automobile, when the wiper blade contacts the windshield of the automobile, the secondary frame is prone to excessive downward pressure, causing the wiper blade to be pressed down by excessive elastic force. After being used for a period of time, the rubber material of the wiper blade is prone to wear, resulting in frictional noise or scratching of the windshield.

[0070] Of course, the present invention can also have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention. However, these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.
