Description

Technical Field

[0001] This application belongs to the field of automotive parts technology, and specifically relates to a novel wiper shaft sleeve structure. Background Technology

[0002] Currently, most windshield trim panels and their matching with surrounding windshields / wiper shafts on the market fall into two categories: One method involves directly connecting the windshield trim panel to the windshield glass using adhesive strips. The adhesive strips are installed on the windshield trim panel, and the windshield trim panel is matched with the wiper shaft. Due to the need to reserve space for the assembly path when the windshield trim panel is installed on the glass, the windshield trim panel needs to have a large hole to avoid this. Another type is where the windshield trim panel is directly clipped onto the windshield. The windshield has adhesive strips that allow the trim panel to be clipped onto it. The trim panel is positioned to match the wiper shaft. A circular rubber sleeve is added to the trim panel to reduce the gap between them and prevent debris such as leaves from entering the cabin.

[0003] Both of these methods of matching the windshield trim panel with the windshield glass have their advantages and disadvantages: The first matching structure has a significant cost advantage, but considering that the front windshield trim panel has a direct opening to avoid the wiper shaft in this structure, it is much worse in terms of aesthetics and functionality, and is becoming less and less accepted by the market. Another matching structure is better in terms of aesthetics and functionality, and is more easily accepted by the market. However, it is more expensive, and the wiper shaft sleeve in this matching structure is only applicable to a single type of vehicle and cannot accommodate multiple matching structures. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a novel wiper shaft sheath structure.

[0005] A novel wiper shaft sleeve structure includes a windshield, a windshield trim panel, a wiper shaft, and a wiper shaft sleeve. The windshield trim panel has mounting holes. The wiper shaft sleeve is installed in the mounting holes via a snap-fit ​​structure. A deformable structure is located in the center of the wiper shaft sleeve. The wiper shaft sleeve adapts to the wiper shaft via the deformable structure, allowing the wiper shaft to pass through the mounting holes in the windshield trim panel. The windshield trim panel and the windshield are fixedly connected via a windshield sealant strip or a windshield CLK structure.

[0006] Preferably, the snap-fit ​​structure includes an annular mounting plate and an annular retaining plate; the annular mounting plate has an L-shaped cross-section on one side; the top end of the annular mounting plate is fixed to the bottom end of the wiper shaft sleeve; and the annular retaining plate is fixed to the horizontal end of the bottom of the annular mounting plate.

[0007] Preferably, the cross-section of the annular plate is an inverted "V" shape.

[0008] Preferably, the end diameter of the annular plate is larger than the diameter of the wiper shaft sleeve.

[0009] Preferably, the deformable structure includes a through hole and spoke clips; the wiper shaft sleeve has a through hole in the middle; the spoke clips are evenly distributed circumferentially along the central through hole of the wiper shaft sleeve and extend from the inner wall of the through hole to the outer edge of the wiper shaft sleeve.

[0010] Preferably, there are 6 spoke clips, with gaps formed between adjacent spoke clips.

[0011] Preferably, the spoke buckle is viewed from above as an inverted isosceles trapezoid, and all corners of the spoke buckle are chamfered.

[0012] Preferably, a support plate is fixedly connected between the bottom end of the spoke buckle and the inner ring wall of the annular mounting plate.

[0013] Preferably, the support plate is a right-angled triangle.

[0014] Preferably, the wiper shaft sleeve, the annular mounting plate, and the annular retaining plate are an integrated structure.

[0015] Compared with the prior art, this application has the following advantages: This new wiper shaft sleeve structure, taking into account cost, aesthetics, and the function of preventing debris from entering the engine compartment, achieves universality for different structures, saving development costs for subsequent projects.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] like Figure 1 , 5 As shown in Figure 6, a novel wiper shaft sleeve 1 structure includes a windshield 2, a windshield trim panel 4, a wiper shaft 3, and a wiper shaft sleeve 1. The windshield trim panel 4 has mounting holes. The wiper shaft sleeve 1 is installed in the mounting holes of the windshield trim panel 4 via a snap-fit ​​structure. A deformable structure is provided in the middle of the wiper shaft sleeve 1. The wiper shaft sleeve 1 adapts to the wiper shaft 3 via the deformable structure, allowing the wiper shaft 3 to pass through the mounting holes of the windshield trim panel 4. The windshield trim panel 4 and the windshield 2 are fixedly connected via a windshield sealant strip 5 or a windshield CLK structure 6. like Figure 2 , Figure 3 , Figure 4 As shown, the snap-fit ​​structure includes an annular mounting plate 12 and an annular retaining plate 13; the annular mounting plate 12 has an L-shaped cross-section on one side; the top end of the annular mounting plate 12 is fixed to the bottom end of the wiper shaft sleeve 1; the annular retaining plate 13 is fixed to the horizontal end of the bottom end of the annular mounting plate 12; the cross-section of the annular retaining plate 13 is an inverted "V" shape; the diameter of the top end of the annular retaining plate 13 is larger than the diameter of the wiper shaft sleeve 1; The deformable structure includes a through hole 11 and spoke clips 14; the wiper shaft sleeve 1 has a through hole 11 in the middle; the spoke clips 14 are evenly distributed circumferentially along the central through hole 11 of the wiper shaft sleeve 1, and extend from the inner wall of the through hole 11 to the outer edge of the wiper shaft sleeve 1; there are 6 spoke clips 14, and a gap is formed between adjacent spoke clips 14; the wiper shaft sleeve 1, the annular mounting plate 12, and the annular clip 13 are an integrated structure; like Figure 5 The diagram shows the type of adhesive strip clip structure between the windshield trim panel 4 and the windshield glass 2, as well as a cross-sectional view of the surrounding components. The cross-section includes the wiper shaft sleeve 1, the windshield glass 2, the wiper shaft 3, the windshield trim panel 4, and the windshield adhesive strip 5. With this existing matching structure, during the assembly of the windshield adhesive strip 5 to the designed position on the windshield glass 2, there will be a relative displacement between the wiper shaft 3 and the windshield trim panel 4. This results in the windshield trim panel 4 needing to be opened at the position where it mates with the wiper shaft 3. A large through-hole is used to absorb the relative movement between the two, but this results in a hole at the mating point, which is not only aesthetically unappealing but also ineffective at blocking leaves and other debris. The wiper shaft sleeve 1 added in this paper can perfectly solve this problem. At the mating point between the wiper shaft sleeve 1 and the wiper shaft 3, the deformable structure can resolve the gap between the wiper shaft 3 and the windshield trim panel 4 by deforming during relative displacement. When assembled to the designed position, the deformable structure springs back to the designed state. The wiper shaft sleeve 1 in Figure 6 The front windshield trim panel 4 can also be perfectly matched with the CLK structure type 6 peripheral parts of the front windshield glass, realizing the universality of this structure; When the wiper shaft sleeve 1 is installed into the mounting hole of the front windshield trim panel 4, the annular retaining plate 13 is made of an elastically deformable material. Because the annular retaining plate 13 is set in an inverted "V" shape, after the annular retaining plate 13 is inserted into the mounting hole of the front windshield trim panel 4, the annular retaining plate 13 will deform slightly. After the annular retaining plate 13 is fully inserted into the mounting hole of the front windshield trim panel 4, the annular retaining plate returns to its original shape and fits against the bottom of the mounting hole of the front windshield trim panel 4. At the same time, the wiper shaft sleeve 1 fits against the front windshield trim panel 4, so that the wiper shaft sleeve 1 and the annular retaining plate 13 cover the edge of the mounting hole wall of the front windshield trim panel 4, ensuring installation stability.

[0022] As can be seen from the above, the mounting holes of the windshield trim panel 4 are connected to the wiper shaft sleeve 1 through a snap-fit ​​structure. The wiper shaft sleeve 1 body is deformed to adapt to the installation position of the wiper shaft 3, ensuring sealing and stability. The fixed connection between the windshield trim panel 4 and the windshield glass 2 can improve assembly efficiency and enhance sealing performance. The snap-fit ​​structure between the wiper shaft sleeve 1 and the windshield trim panel 4 fits tightly, effectively preventing abnormal noise and loosening. The overall structure is simplified and easy to disassemble and maintain.

[0023] like Figure 2 and 4 As shown, the spoke buckle 14 is an inverted isosceles trapezoid in plan view, and all corners of the spoke buckle 14 are chamfered; a support plate 15 is fixed between the bottom end of the spoke buckle 14 and the inner ring wall of the annular mounting plate 12; the support plate 15 is a right triangle in shape. The spoke clip 14 has chamfered corners, which facilitates its installation and fit with the wiper shaft 3 without damage. At the same time, the support plate 15 ensures that the spoke clip 14 will not break when it deforms, thus ensuring the quality of the deformation of the spoke clip 14. The support plate 15 is a right triangle, which ensures the support stability of the support plate 15.

[0024] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
