Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-2 As shown, a car windshield wiper includes: a wiper blade 1; the wiper blade 1 includes a positioning member 101 for positioning the wiper blade 1 and a swing member 102 for contacting the windshield of the car; the swing member 102 includes a rectangular strip 1021, a connecting plate 1022, a semi-cylinder 1023, and a wiper blade 1024; the top surface of the rectangular strip 1021 is integrally connected to the bottom surface of the positioning member 101, and the bottom surface of the rectangular strip 1021 is integrally connected to the connecting plate 1022; the bottom surface of the connecting plate 1022 is integrally connected to the semi-cylinder 1023. The rectangular surface of the semi-cylinder 1023; multiple scraper blades 1024 are integrally connected along the axial direction on the arc surface of the semi-cylinder 1023; a groove 1025 is formed between adjacent scraper blades 1024 for the oscillation of the scraper blades 1024; a protective shell 2; the protective shell 2 is connected to the positioning member 101, and the positioning member 101 is located inside the protective shell 2; an end cap 3; two end caps 3 are provided, and the two end caps 3 are respectively snapped into both ends of the protective shell 2; a buckle 4; the buckle 4 is located in the middle of the top surface of the protective shell 2 and is detachably connected to the car wiper arm.

[0020] In the present utility model, both the positioning member 101 and the swinging member 102 are made of natural rubber; the positioning member 101 is configured to position the swinging member 102 at the lower end of the protective housing 2; the arc-shaped surface of the semi-cylinder 1023 is integrally connected with a plurality of scrapers 1024 along the axial direction, and a groove 1025 is reserved between adjacent scrapers 1024, the space size of the groove 1025 is adapted to the swinging amplitude of the scrapers 1024, so as to avoid excessive interference when the scrapers 1024 swing; the plurality of scrapers 1024 are distributed along the arc-shaped surface of the semi-cylinder 1023. When the wiper performs a reciprocating fan-shaped movement, the scrapers 1024 can perform multiple progressive scraping on water stains and dirt on the front windshield. Compared with the traditional single scraper, the scraping coverage is more comprehensive; the groove 1025 provides sufficient swinging space for the scrapers 1024, enabling the scrapers 1024 to adapt to the curvature of the glass curved surface, effectively reducing the phenomenon of missed scraping or residue, and significantly improving the clarity of the driver's vision in bad weather.

[0021] As Figure 1-2 shows, a placement slot 201 with a vertical cross-section in a "gan" shape is provided inside the protective housing 2; the vertical cross-section of the positioning member 101 is in a "wang" shape; the upper transverse plate, the middle transverse plate and the vertical plate of the positioning member 101 are located in the placement slot 201, and the lower transverse plate is located at the lower end of the protective housing 2; the middle position of the bottom surface of the lower transverse plate of the positioning member 101 is integrally connected with the top surface of the rectangular bar 1021.

[0022] In the present utility model, the adapting structure of the gan-shaped placement slot 201 of the protective housing 2 and the wang-shaped cross-section of the positioning member 101 forms multi-dimensional limiting. The upper transverse plate and the middle transverse plate of the positioning member 101 are respectively arranged in corresponding regions of the placement slot 201, limiting the vertical displacement of the positioning member 101; the tight fit between the vertical plate of the positioning member 101 and the vertical slot of the placement slot 201 further prevents the positioning member 101 from shaking left and right.

[0023] As Figure 1-2 shows, a first through hole 10231 is provided along the axial direction of the semi-cylinder 1023; on one hand, the first through hole 10231 reduces the overall weight of the swinging member 102, reduces the driving load of the wiper arm, and indirectly reduces the energy consumption of the automobile wiper motor; on the other hand, the first through hole 10231 enables the arc-shaped surface of the semi-cylinder 1023 to have better elastic deformation capability. When the scraper 1024 contacts the glass, the semi-cylinder 1023 can deform slightly, so that the contact pressure between the scraper 1024 and the glass surface is more uniform, which not only avoids glass scratches caused by excessive local pressure, but also improves the fitting degree between the scraper 1024 and the glass, and further optimizes the scraping cleanliness.

[0024] As Figure 1-2As shown, the width of the connecting plate 1022 is greater than the width of the rectangular surface of the semi-cylinder 1023; the rectangular surface of the semi-cylinder 1023 is integrally connected to the middle position of the bottom surface of the connecting plate 1022; a scraper 1024 is integrally connected to the bottom end of the semi-cylinder 1023; multiple scrapers 1024 are integrally connected to both ends of the scraper 1024 at the bottom end of the semi-cylinder 1023 facing the connecting plate 1022.

[0025] In this utility model, the width of the connecting plate 1022 is greater than the width of the rectangular surface of the semi-cylinder 1023, and the semi-cylinder 1023 is fixed in the middle of the bottom surface of the connecting plate 1022 to ensure that the semi-cylinder 1023 is subjected to balanced force and to avoid the scraper 1024 from tilting due to installation offset.

[0026] like Figure 3-4 As shown, two locking blocks 5 are connected to the two ends of the top surface of the protective shell 2 respectively; the end cap 3 is a hollow structure, and the bottom end and the end facing the protective shell 2 are open; the inner top surface of the end cap 3 has two slots 301 corresponding to the two locking blocks 5 at one end of the protective shell 2, and the slots 301 are connected to the end cap 3 facing the protective shell 2; the locking blocks 5 are engaged with the slots 301.

[0027] like Figure 3-4 As shown, the two ends of the protective shell 2 are respectively connected to the two end blocks 6; the two inner sides of the end cap 3 are respectively provided with the slots 302 corresponding to the slots 6 at one end of the protective shell 2, and the slots 302 are connected to the end of the end cap 3 facing the protective shell 2; the slots 6 and the slots 302 are engaged; when in use, the function of the end cap 3 is to prevent the wiper blade 2 from running out of the outside of the protective shell 2.

[0028] like Figure 1-3 As shown, the vertical cross-section of the vertical plate of the positioning component 101 is an isosceles trapezoid, and the width of the upper base of the isosceles trapezoid is smaller than the width of its lower base.

[0029] In this utility model, the isosceles trapezoidal cross-section with a narrow top and wide bottom on the vertical plate of the positioning member 101 matches the vertical groove of the placement groove 201, and there is no gap after embedding, which further enhances the stability of the positioning member 101. Compared with the vertical cross-section of the positioning member 101 being set as a rectangle, when the vertical plate of the positioning member 101 moves slightly downward, the isosceles trapezoidal cross-section with a narrow top and wide bottom is easier to return to its position, ensuring that the scraper 1024 scrapes smoothly without any jamming.

[0030] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
