[0002] Windshield wipers, also known as wipers, are devices used to wipe away raindrops and dust adhering to the windshield of a vehicle, in order to improve the driver's visibility and increase driving safety.
[0003] The main steel blade of the windshield wiper is connected to the wiper arm outside the car's windshield via a connector and adapter. However, this method is complex, resulting in too many components in the wiper, which reduces production efficiency in actual wiper manufacturing. Therefore, it is necessary to design a wiper that can be assembled into a robust wiper through the cooperation of the main structure. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a car windshield wiper.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A car windshield wiper includes a wiper blade, stainless steel sheets clipped to both sides of the wiper blade, rigid air deflectors fastened to both ends of the wiper blade for securing the stainless steel sheets, a mounting base located in the middle section of the wiper blade and mounted with the stainless steel sheets, and a buckle mounted on the mounting base. The outer side of the middle section of the stainless steel sheets has two fastening grooves for fitting with the mounting base, and the outer side of the end of the stainless steel sheets has a chamfered fastening head integrally formed for fitting with the rigid air deflectors. The mounting base 4 includes a first side bracket and a second side bracket for fastening and fixing the two stainless steel sheets respectively, and a long stud for connecting and fixing the first side bracket and the second side bracket.
[0007] Preferably, the fastening groove includes a fastening groove inlet, a sliding section that slopes inward from the fastening groove inlet, and a limiting section located at the end of the sliding section.
[0008] Furthermore, the lower end of the first side mounting bracket is integrally formed with a first side mounting C-shaped foot fitted with a stainless steel sheet, and the inside of the first side mounting C-shaped foot is integrally formed with a first side mounting clip that assembles with the fastening groove.
[0009] Furthermore, an upper stacking plate is integrally formed on the inner side of the first side mounting bracket near the C-shaped foot of the first side mounting bracket;
[0010] Furthermore, the upper inner side of the first side bracket has an integrally formed first side mounting post with an internally threaded hole.
[0011] Furthermore, the lower end of the second side mounting bracket is integrally formed with a second side mounting C-shaped foot fitted with a stainless steel sheet, and the interior of the second side mounting C-shaped foot is integrally formed with a second side mounting clip that assembles with the fastening groove.
[0012] Furthermore, a lower stacking plate is integrally formed on the inner side of the second side mounting bracket near the C-shaped foot of the second side mounting bracket;
[0013] Furthermore, the upper inner side of the second side bracket has an integrally formed second side mounting post with an internally threaded hole.
[0014] Preferably, the rigid fairing includes a rigid fairing body, a support plate integrally formed at the bottom of the rigid fairing body for tightly abutting the stainless steel sheet, an anti-detachment protrusion integrally formed at the end of the rigid fairing body, and an anti-detachment groove formed at the end of the rigid fairing body to cooperate with the anti-detachment protrusion to fix the fastener head.
[0015] The beneficial effects of the utility model are:
[0016] 1. Improved assembly efficiency and reliability: The structure of the snap-fit groove inlet, sliding section and limiting section makes the connection between the stainless steel sheet and the fixed seat smoother and more stable. During installation, the snap-fit can be completed accurately and quickly by aligning the snap-fit groove inlet and guiding the sliding section, which simplifies the assembly process and reduces the difficulty of manual installation. The design of the snap-fit groove and the locking post of the stainless steel sheet and the fixed seat can not only be assembled quickly, but also ensure that the parts will not loosen or fall off during use, thus improving the overall assembly accuracy and reliability.
[0017] 2. Enhanced structural strength and stability: The mounting base consists of three parts: a first side bracket, a second side bracket, and long studs. The studs secure the connection, effectively increasing the structural strength of the mounting base and preventing parts from loosening or being damaged due to vibration or external forces during assembly. The upper plate of the first side bracket and the lower plate of the second side bracket are connected by stacking, which limits the distance between the brackets and enhances the overall strength of the mounting base, providing better impact resistance and durability.
[0018] 3. Improved durability and anti-detachment function: The design of the anti-detachment protrusion and the fastening head of the rigid windshield prevents the windshield from falling off due to external force or vibration. The chamfered design of the fastening head and the elastic deformation of the anti-detachment protrusion make the windshield more securely fixed, preventing loosening or falling off during long-term use, thereby improving the service life of the wipers.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.
[0027] Example
[0028] like Figure 1-7 As shown, a car windshield wiper includes a wiper blade 1, stainless steel sheets 2 clipped to both sides of the wiper blade 1, rigid air deflectors 3 fastened to both ends of the wiper blade 1 for securing the stainless steel sheets 2, a mounting base 4 located in the middle section of the wiper blade 1 and mounted to the stainless steel sheets 2, and a buckle 5 mounted on the mounting base 4.
[0029] The outer edge of the middle section of the stainless steel sheet 2 is provided with two fastening grooves 21 for assembly with the fixing seat 4. The outer edge of the end of the stainless steel sheet 2 is integrally formed with a fastening head 22 that is assembled with the rigid guide shroud 3 and has been chamfered. The fixing seat 4 includes a first side bracket 41 and a second side bracket 42 that are fastened and fixed to the two stainless steel sheets 2 respectively, and a long stud 43 that connects and fixes the first side bracket 41 and the second side bracket 42.
[0030] The fastening groove 21 includes a fastening groove inlet 211, a sliding section 212 that extends inward from the fastening groove inlet 211, and a limiting section 213 located at the end of the sliding section 212.
[0031] The lower end of the first side mounting bracket 41 is integrally formed with a first side mounting C-shaped foot 411 for fitting stainless steel sheet 2. The inside of the first side mounting C-shaped foot 411 is integrally formed with a first side mounting post 412 for fitting with the fastening groove 21. The inner side of the first side mounting bracket 41 near the first side mounting C-shaped foot 411 is integrally formed with an upper stacking plate 413. The upper inner side of the first side mounting bracket 41 is integrally formed with a first side mounting post 414 with an internal threaded hole.
[0032] The lower end of the second side mounting bracket 42 is integrally formed with a second side mounting C-shaped foot 421 for fitting stainless steel sheet 2. The interior of the second side mounting C-shaped foot 421 is integrally formed with a second side mounting pin 422 for fitting with the fastening groove 21. The inner side of the second side mounting bracket 42 near the second side mounting C-shaped foot 421 is integrally formed with a lower stacking plate 423. Specifically, the lower stacking plate 423 and the upper stacking plate 413 are stacked, which not only limits the distance between the first side mounting bracket 41 and the second side mounting bracket 42, but also improves the structural strength of the entire fixing base 4 by stacking the lower stacking plate 423 and the upper stacking plate 413 after assembly.
[0033] The upper inner side of the second side bracket 42 has an integrally formed second side bracket post 424 with an internal threaded hole. Specifically, the first side bracket 41 and the second side bracket 42 can be fastened by connecting the second side bracket post 424 with the first side bracket post 414 and then screwing in the long stud post 43, thus forming a structurally stable fixing seat 4.
[0034] It should be further explained that before the first side-mounted C-shaped foot 411 is fitted with the stainless steel sheet 2, the first side-mounted locking post 412 needs to be aligned with the fastening groove inlet 211 of the fastening groove 21. Then, it is pushed along the direction of the fastening groove inlet 211, so that the first side-mounted locking post 412 slides from the fastening groove inlet 211 into the inner inclined sliding section 212. At this time, the first side-mounted C-shaped foot 411 becomes closer and closer to the stainless steel sheet 2, until the first side-mounted locking post 412 is completely inserted into the limiting section 213 at the end of the sliding section 212, thus completing the fastening of the first side-mounted bracket 41 and the stainless steel sheet 2. Similarly, before fitting the second side mounting C-shaped foot 421 to the stainless steel sheet 2, the second side mounting pin 422 needs to be aligned with the fastening groove inlet 211 of the fastening groove 21. Then, push it along the direction of the fastening groove inlet 211 so that the second side mounting pin 422 slides from the fastening groove inlet 211 into the inner inclined sliding section 212. At this time, the second side mounting C-shaped foot 421 becomes closer and closer to the stainless steel sheet 2 until the second side mounting pin 422 is completely inserted into the limiting section 213 at the end of the sliding section 212, thus completing the fastening and fixing of the second side mounting bracket 42 to the stainless steel sheet 2.
[0035] The rigid fairing 3 includes a rigid fairing body 31, a support plate 32 integrally formed at the bottom of the rigid fairing body 31 for tightly attaching to the stainless steel sheet 2, an anti-detachment protrusion 33 integrally formed at the end of the rigid fairing body 31, and an anti-detachment groove 34 formed at the end of the rigid fairing body 31 to cooperate with the anti-detachment protrusion 33 to fix the fastener head 22.
[0036] Specifically, when the rigid windshield cover 3 is used in conjunction with the wiper blade 1 and the stainless steel sheet 2, the rigid windshield cover body 31 is inserted into the mounting head 22 end of the stainless steel sheet 2 with the support plate 32. The stainless steel sheet 2 is in close contact with the support plate 32 and slides through the groove formed by the support plate 32 and the rigid windshield cover body 31 until the mounting head 22 abuts against the anti-detachment protrusion 33. Then, with a forceful push, the chamfered end of the mounting head 22 is squeezed by the anti-detachment protrusion 33 and temporarily deforms inward elastically. After passing the anti-detachment protrusion 33, it returns to its original position. Then, the mounting head 22 is embedded in the anti-detachment groove 34 and returns to its original position through the anti-detachment protrusion 33. At this time, the rigid windshield cover 3 is fixedly installed.
[0037] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of this utility model, shall fall within the scope of protection of this utility model.
