It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0030] The following reference Figures 1 to 4 This application describes a nut mounting cover for a windshield wiper provided according to some embodiments.

[0031] like Figure 1-4 As shown, the wiper nut mounting cover provided according to some embodiments of this application includes a cap 100, a cover body 200, engaging teeth 300, a buffer groove 400, and a magnetic layer 500. The cover body 200 is connected to the cap 100, and a receiving cavity is formed between the cap 100 and the cover body 200. Multiple engaging teeth 300 are evenly disposed on the inner wall of the cover body 200, and the engaging teeth 300 can engage with the nut received in the receiving cavity. Multiple buffer grooves 400 are spaced apart on the cover body 200 and communicate with the receiving cavity. The magnetic layer 500 is evenly disposed on the cap 100 and the multiple engaging teeth 300, and is used to assist the cover body 200 in being assembled to the outside of the nut.

[0032] In this embodiment, the cap 100 is connected to the cover body 200, and a receiving cavity is formed between them to accommodate the nut. When installed outside the nut, it can protect the nut and prevent external impurities from contacting it. The shape and size of the meshing teeth 300 are matched with the nut housed in the receiving cavity to ensure that the meshing teeth 300 can fit tightly with the nut and achieve a stable connection. Multiple buffer grooves 400 are provided at intervals on the cover body 200 and communicate with the receiving cavity to provide a certain buffer space to release the radial stress of the cover body 200 and prevent the cover body 200 from cracking after the nut is engaged. The magnetic layer 500 is evenly disposed on the cap 100 and the multiple meshing teeth 300. The magnetic layer 500 is made of magnetic material, which allows the cover body 200 to be pre-positioned when installed outside the nut, improving the ease of installation.

[0033] In some possible embodiments, the cap 100, the cover 200, and the meshing teeth 300 are all made of plastic.

[0034] In this embodiment, the mounting cover is made entirely of plastic material, which is not easily rusted or corroded in harsh environments such as humidity and salt spray. It is also suitable for outdoor wipers and other devices that are exposed to rain and ultraviolet radiation for a long time, thus improving the overall service life of the mounting cover and reducing costs.

[0035] In some possible embodiments, such as Figure 1 As shown, the cap 100, the cover body 200 and the meshing teeth 300 are designed as a single unit.

[0036] In this embodiment, the integrated design of the cap 100, the cover body 200 and the meshing teeth 300 is interconnected by molecular chains, which makes it stronger than the separate assembly. It can withstand greater torque and impact, and the integrated design has a better sealing effect, effectively preventing dust and moisture from entering the cover body 200 and preventing the nut from rusting or corroding.

[0037] In some possible embodiments, such as Figure 1 , Figure 2 As shown, the diameter of the cap 100 is larger than the diameter of the cover 200.

[0038] In this embodiment, the diameter of the cap 100 is larger than that of the cover 200, and the diameter difference between the cap 100 and the cover 200 forms a stepped structure. The cap 100 is easy for the user to grip with their fingers, thus enabling quick installation.

[0039] In some possible embodiments, such as Figure 2 As shown, the cap 100 is in the shape of an arc groove, and the cover body 200 is in the shape of a cylinder. The cover body 200 is located inside the arc groove of the cap 100.

[0040] In this embodiment, the arc-shaped structure of the cap 100 can reduce the probability of the cover 200 being deformed due to external impact by dispersing stress. In addition, the cap 100 can shield the cover 200, preventing highly corrosive impurities from directly contacting the cover 200 and accelerating the corrosion rate, thus providing a certain degree of protection for the cover 200.

[0041] In some possible embodiments, such as Figure 1 , Figure 3 As shown, there are 12 meshing teeth 300 in total. Adjacent meshing teeth 300 are connected to each other and are evenly distributed in the cover body 200 in a serrated shape.

[0042] In this embodiment, there are 12 meshing teeth 300 arranged in a circle inside the cover 200.

[0043] In some possible embodiments, such as Figure 3 As shown, the angle between two adjacent meshing teeth 300 is 120°, which matches the corner of the nut.

[0044] In this embodiment, the 120° angle between the meshing teeth 300 allows the 12 meshing teeth 300 to form 6 sets of symmetrically distributed three-tooth units. The six corners of the internal hexagonal nut can be arbitrarily inserted into any set, realizing installation at 6 different starting angles, reducing the difficulty of operation and improving the ease of installation. The corners of the nut fit snugly with the meshing teeth 300, improving the stability of the mounting cover and preventing it from falling off.

[0045] In some possible embodiments, such as Figure 4 As shown, the end of each meshing tooth 300 facing away from the cap 100 is chamfered at an angle of 30°, which is used to guide the cap 200 to be smoothly installed to the outside of the nut.

[0046] In this embodiment, a 30° chamfer forms a gradual slope. When the cover 200 approaches the nut, the chamfered end of the meshing tooth 300 first contacts the outer edge of the nut. The slope guides the automatic calibration position, improving installation efficiency and making it suitable for environments with limited installation space or insufficient light, thus enhancing the practicality of this mounting cover.

[0047] In some possible embodiments, such as Figure 1 As shown, there are a total of 4 buffer grooves 400, which are evenly spaced on the side of the cover 200 away from the cap 100.

[0048] In this embodiment, four buffer grooves 400 are evenly distributed on the circumference of the cover 200, so that the external force is evenly distributed to the entire cover through the grooves, providing a buffering effect, releasing the radial stress of the cover 200, and preventing the cover 200 from cracking after the nut is engaged.

[0049] In some possible embodiments, such as Figure 4 As shown, the thickness of the magnetic layer 500 ranges from 0.02mm to 0.05mm.

[0050] In this embodiment, the 0.02mm-0.05mm magnetic layer 500 can generate sufficient magnetic force to allow the cover 200 to automatically adhere and fit when it approaches the nut, without the need for repeated manual adjustments. This achieves rapid fixation through weak magnetic adsorption.

[0051] When installing the nut cover for this windshield wiper, the user holds the cap 100 and brings the cover 200 close to the nut. The magnetic layer 500 uses weak magnetic force to automatically attract the cover to the outside of the nut. The 30° chamfer of the meshing teeth 300 contacts the outer edge of the nut. The cover 200 is automatically adjusted in angle by the inclined surface, so that the corners of the nut are aligned with the serrated surface of the meshing teeth 300. The 12 meshing teeth 300 are arranged in a circle with an angle of 120° between adjacent teeth, forming 6 sets of symmetrical three-tooth units. Any of the six corners of the nut can be inserted into any set, achieving 6 different starting angles for installation. The meshing teeth 300 fit snugly against the corners of the nut, achieving a stable connection. During installation, the buffer groove 400 provides buffer space to release the radial stress of the cover 200 and prevent the cover 200 from cracking after the nut is engaged. The receiving cavity formed by the cap 100 and the cover 200 encloses the nut and prevents external impurities from contacting it.
