Description

Technical Field

[0001] This application relates to a wiper structure, and particularly to an assembly structure of a multi-section wiper. Background Art

[0002] Generally, a wiper structure mainly combines a wiper blade at the bottom side of a fixed bracket, and the fixed bracket is driven by an automotive driving arm to press the wiper blade against the glass for cleaning.

[0003] Moreover, in the design of the wiper structure, the wiper blade needs to be closely attached to the automotive glass to effectively wipe off rainwater. In this regard, the industry has currently designed a multi-section wiper, which is provided with multiple groups of brackets at the bottom of the fixed bracket to perform multi-section pressing on the elastic sheet, so that the wiper blade combined at the bottom of the elastic sheet can be evenly pressed and better fit the glass, thereby achieving the purpose of effectively cleaning the glass.

[0004] Furthermore, most of the multiple groups of brackets of the aforementioned wiper structure are combined with the fixed bracket by pivoting or rotary snap-fitting. However, the assembly method using pivoting is cumbersome and time-consuming, resulting in an increase in manufacturing cost. In addition, the assembly method using rotary snap-fitting is prone to detachment during the swinging process, causing inconvenience in use.

[0005] In view of this, the inventors of this application specifically studied the above-mentioned prior art with great concentration and applied academic principles to try their best to solve the above problems, which became the goal of the inventors of this application. Summary of the Invention

[0006] This application provides an assembly structure of a multi-section wiper, in which the pressing piece is quickly combined with the elastic sheet through a snap-fastening group, increasing the convenience during assembly.

[0007] This application provides an assembly structure of a multi-section wiper, in which there is a good clamping and positioning effect between the fixed bolt seat and the pin member of the snap-fastening group, so the pressing piece can be stably combined with the elastic sheet, increasing the stability during use.

[0008] To achieve the above object, the present application provides an assembly structure of a multi-section wiper, which includes a fixing frame, a pair of elastic arms, two or more pressing groups, and a wiper strip. The fixing frame includes a fixing base and a pair of side wings connected to opposite sides of the fixing base. A pair of elastic arms are respectively combined on the pair of side wings, and each elastic arm has two or more openings. Two or more pressing groups are correspondingly arranged with respect to the openings and combined on the pair of elastic arms. Each pressing group includes a pressing piece and a snap group. The pressing piece is provided with a slot corresponding to each opening. The snap group includes a fixing bolt seat and a pin member inserted through the fixing bolt seat. The fixing bolt seat penetrates into the opening and the slot from one side of the elastic arm, and the pin member is inserted into the fixing bolt seat from one side of the pressing piece. The fixing bolt seat and the pin member are snapped with each other to clamp the elastic arm and the pressing piece, so that the pressing piece is combined with the elastic arm without loosening.

[0009] The present application provides an assembly structure of a multi-section wiper, which may further include two or more pressing strips to assist and strengthen the pressure of the pressing piece on the wiper strip, so that the pressing force received by the wiper strip is more uniform, and thus a more reliable cleaning effect is achieved.

[0010] Compared with the prior art, the pressing piece of the multi-section wiper of the present application can be quickly combined with the elastic piece through the snap group. In addition, the fixing bolt seat and the pin member of the snap group have a good clamping effect after being snapped with each other, thereby firmly combining the pressing piece on the elastic piece without loosening, and achieving the purpose of quickly combining the pressing piece and the elastic arm, thereby increasing the convenience during assembly and the practicality in use.

[0046] The detailed description and technical content of this application will be described below in conjunction with the drawings. However, the attached drawings are only for illustrative purposes and are not intended to limit this application.

[0047] Please refer to Figure 1 and Figure 2 as shown, which is a three-dimensional exploded view and a combined cross-sectional view showing the assembly structure of the multi-section windshield wiper of the present application. The present application provides an assembly structure of a multi-section windshield wiper 1, including a fixing frame 10, a pair of elastic arms 20, two or more pressing groups 30, and a wiper strip 40. The pair of elastic arms 20 are coupled to the fixing frame 10. The pressing groups 30 are symmetrically arranged on the pair of elastic arms 20 for coupling the wiper strip 40, thereby forming the multi-section windshield wiper 1.

[0048] The fixing frame 10 includes a fixing base 11 and a pair of side wings 12 connected to opposite sides of the fixing base 11. Further, the pair of elastic arms 20 are respectively coupled to the pair of side wings 12.

[0049] In addition, the multi-section windshield wiper 1 further includes a pair of pivot shafts 22 and a pair of pivot seats 23. Further, each of the side wings 12 has a pivot hole 120. Each of the pivot seats 23 is disposed on each of the elastic arms 20. The pair of elastic arms 20 are pivotally connected to the pair of side wings 12 by passing the pair of pivot shafts 22 through the pivot seats 23 and the pivot holes 120.

[0050] Furthermore, the pressing groups 30 are disposed corresponding to the openings 21 and coupled to the pair of elastic arms 20. The wiper strip 40 is coupled to the bottom side of the pressing pieces 31 of the pressing groups 30. Accordingly, the pressing groups 30 perform multi-section pressing on the wiper strip 40, so that the wiper strip 40 can tightly press against the glass surface, thereby scraping off rainwater or foreign objects on the glass surface.

[0051] In an embodiment of the present application, the pressing group 30 of the multi-section windshield wiper 1 further includes two or more frame pieces 33. The frame pieces 33 are coupled to the pressing piece 31 to pass through the wiper strip 40.

[0052] Please also refer to Figures 3 to 6 as shown, which is a three-dimensional external view, a three-dimensional exploded view, a planar sectional exploded view, and a combined cross-sectional view of the elastic arm and the pressing group after combination of the present application.

[0053] In an embodiment of the present application, each of the elastic arms 20 has two or more openings 21. Further, each of the pressing groups 30 includes a pressing piece 31 and a buckle group 32. The pressing piece 31 is provided with a slot 310 corresponding to each of the openings 21.

[0054] Furthermore, the buckle assembly 32 includes a fixing bolt seat 321 and a latch member 322 penetrating the fixing bolt seat 321. The fixing bolt seat 321 penetrates the opening 21 and the slot 310 from one side of the elastic arm 20. The latch member 322 penetrates the fixing bolt seat 321 from one side of the pressing plate 31. Accordingly, the fixing bolt seat 321 and the latch member 322 are mutually locked to clamp the elastic arm 20 and the pressing plate 31, so that the pressing plate 31 is combined with the elastic arm 20 and does not loosen.

[0055] Specifically, the fixing bolt seat 321 includes a bolt cover 3211, two clips 3212 connected to the bolt cover 3211, and a latching space 3210 located between the two clips 3212. In addition, the latch member 322 includes a cap 3221 and an insertion rod 3222 connected to the cap 3221. The insertion rod 3222 is inserted into the latching space 3210, and the ends of the two clips 3212 abut against the cap 3221.

[0056] In the embodiment of the present application, the fixing bolt seat 321 is formed with a groove 3213 on the inner wall surface of the two clips 3212. In addition, the latch member 322 is formed with a protrusion 3223 on the outer peripheral surface of the plug rod 3222. Thus, the latch member 322 and the fixing bolt seat 321 are combined by the mutual positioning of the protrusion 3223 and the groove 3213, and the latch member 322 is fixed by the elastic clamping of the two clips 3212.

[0057] Specifically, the bolt cover 3211 has an opening 3214 connected to the latch space 3210. Moreover, the groove 3213 is located on the inner wall of the opening 3214. In addition, each of the clips 3212 has a hook 3215. Moreover, the elastic arm 20 and the pressing piece 31 are sandwiched between the hook 3215 and the bolt cover 3211.

[0058] Accordingly, the pressing pieces 31 can be quickly coupled to the elastic piece 20 through the buckle sets 32. In addition, since the fixing bolt seat 321 and the latch member 322 are well locked and fixed so that the latch member 322 will not be separated from the fixing bolt seat 321, the pressing piece 31 can be firmly coupled to the elastic piece 20, thereby increasing the stability during use.

[0059] Please refer to Figure 7 The multi-stage windshield wiper 1 of the present invention may further include two or more pressure strips 50, which are arranged to assist and strengthen the pressure of the pressure plates 31 on the scraper strip 40, so that the pressure on the scraper strip 40 is more uniform, thereby achieving a more reliable cleaning effect.

[0060] The pressing strips 50 are arranged between the fixing base 11 and the scraping strip 40 and press against the glass surface (not shown in the figure) contacted by the scraping strip 40 in a direction away from the fixing base 11. Specifically, the pressing strips 50 are arranged on the latch member 322 and extend between the pressing piece 31 and the scraping strip 40. In the embodiment of the present application, the pressing strips 50 respectively extend outward from the periphery of the cap 3211 of the latch member 322. Accordingly, the pressing strips 50 can assist the pressing piece 31 to press the scraping strip 40 to achieve a more uniform pressing effect.
