[0036] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0037] In the present disclosure, unless otherwise stated, the orientation terms such as "First Direction, Second Direction" refer to two directions in which the wiper blade intersects. For example, the First Direction can be the thickness direction of the wiper, and the Second Direction can be the width direction of the wiper. Specifically, reference can be made to Figure 1 as shown; the terms such as "First, Second" are only used to distinguish one element from another, and do not have sequentiality and importance.

[0038] Referring to Figure 1 and Figure 2 as shown, the present disclosure provides a wiper blade, which includes a wiper sheath 1 and a wiper rubber strip 2. The wiper rubber strip 2 includes a rubber strip base 21 and a rubber strip body 22. The wiper sheath 1 includes a sheath body 11 and a water shielding portion 12.

[0039] The rubber strip base 21 is connected to the sheath body 11. The rubber strip body 22 is connected to the side of the rubber strip base 21 away from the sheath body 11 along the First Direction B, and the rubber strip body 22 is used to contact the vehicle glass and can undergo elastic deformation.

[0040] The water shielding portion 12 is bent and connected to at least one side of the sheath body 11 along the Second Direction C, and the water shielding portion 12 is disposed opposite and spaced from the wiper rubber strip 2 in the Second Direction C to limit the rainwater scraped by the rubber strip body 22 from flowing toward the vehicle A-pillar; wherein, the First Direction B intersects with the Second Direction C.

[0041] In the above technical solution, when the wiper blade is working, the rubber strip body 22 is used to contact the vehicle glass and can undergo elastic deformation to closely adhere to the vehicle glass and scrape the rainwater on the surface. By bending and connecting the water blocking part 12 to at least one side of the sheath body 11 along the second direction C, and the water blocking part 12 is arranged opposite and spaced from the wiper rubber strip 2 in the second direction C, the water blocking part 12 can block the rainwater scraped by the rubber strip body 22 in the second direction C, so that the rainwater flows out from both ends of the wiper blade, as much as possible restricting the rainwater from impacting the vehicle A-pillar along the side of the wiper blade in the second direction C, reducing the rainwater overflowing from the vehicle A-pillar, effectively reducing the coverage area of rainwater in the side window vision area, and improving the driving safety in rainy days.

[0042] Optionally, as shown in Figure 1 and Figure 2 The sheath body 11 includes a first sheath part 111, a second sheath part 112 and a connecting part 113. The first sheath part 111 and the second sheath part 112 are spaced apart in the second direction C and are connected by the connecting part 113 to jointly define a mounting groove 110 recessed in the first direction B. The rubber strip base 21 is at least partially arranged in the mounting groove 110 and is connected to the sheath body 11, and the rubber strip body 22 is arranged outside the mounting groove 110. The water blocking part 12 is bent and connected to the side of the first sheath part 111 away from the second sheath part 112 in the second direction C; and / or, the water blocking part 12 is bent and connected to the side of the second sheath part 112 away from the first sheath part 111 in the second direction C.

[0043] In this embodiment, the water blocking part 12 can be arranged on the first sheath part 111. When installing, it is necessary to make the first sheath part 111 closer to the vehicle A-pillar relative to the second sheath part 112 to reduce the impact of rainwater on the vehicle A-pillar from one side of the first sheath part 111. Or, the water blocking part 12 can be arranged on the second sheath part 112. When installing, it is necessary to make the second sheath part 112 closer to the vehicle A-pillar relative to the first sheath part 111 to reduce the impact of rainwater on the vehicle A-pillar from one side of the second sheath part 112. Or, the water blocking part 12 is arranged on both the first sheath part 111 and the second sheath part 112. When installing the wiper blade on the vehicle, since the water blocking parts 12 are arranged on both sides, there is no need to consider the assembly direction.

[0044] The above-mentioned first sheath part 111, second sheath part 112 and connecting part 113 can be constructed into any suitable shape and structure, and the present disclosure does not limit this. In addition, the first sheath part 111, second sheath part 112 and connecting part 113 can be constructed into an integrally formed structure, which is convenient for processing and manufacturing and improves the structural stability. The defined mounting groove 110 can also be constructed into any suitable shape, and the present disclosure does not limit this either.

[0045] In one embodiment, referring to Figure 1 and Figure 2 as shown, the wiper blade further includes a first elastic support sheet 3 and a second elastic support sheet 4.

[0046] A first card slot 1110 is formed inside the first sheath portion 111, and the opening of the first card slot 1110 faces and communicates with the installation slot 110; a second card slot 1120 is formed inside the second sheath portion 112, and the opening of the second card slot 1120 faces and communicates with the installation slot 110.

[0047] On both sides of the rubber strip base 21 along the second direction C, a third card slot 211 and a fourth card slot 212 are respectively provided. The third card slot 211 is arranged opposite to the first card slot 1110, and the fourth card slot 212 is arranged opposite to the second card slot 1120.

[0048] Wherein, the first elastic support sheet 3 is clamped in the first card slot 1110 and the third card slot 211; the second elastic support sheet 4 is clamped in the second card slot 1120 and the fourth card slot 212.

[0049] It should be noted that the above-mentioned first elastic support sheet 3 and second elastic support sheet 4 mainly play the following roles:

[0050] Providing constant pressure: Through its elastic force characteristics, the elastic support sheet ensures that the wiper blade can be evenly pressed on the automotive windshield, and can maintain good contact even on windshield surfaces with different curvatures.

[0051] Pressure distribution: The elastic support sheet helps to evenly distribute the pressure transmitted by the wiper arm along the entire length of the wiper blade, so as to ensure that the wiper blade will not show the phenomenon of heavy in the middle and light at both ends during operation, and improve the cleaning effect.

[0052] Adaptability: The design of the elastic support sheet enables the wiper blade to better adapt to the shape of the windshield, and can maintain stability even at high speeds or in strong winds, effectively removing rainwater and other dirt.

[0053] Reducing vibration and noise: By optimizing the design of the elastic support sheet, the vibration and noise generated during wiper operation can be reduced, improving the driving experience.

[0054] In this embodiment, by clamping the elastic support sheet between the card slots on the rubber strip base 21 and the card slots of the sheath body 11, while ensuring stable installation, it is also convenient for installation and disassembly. However, the present disclosure does not limit the specific installation method of the elastic support sheet.

[0055] In other embodiments, referring to Figure 1 and Figure 2As shown, the water blocking part 12 is bent and connected to one side of the first sheath part 111 away from the second sheath part 112 in the second direction C. Among them, the dimension of the first sheath part 111 extending along the second direction C is greater than that of the second sheath part 112 extending along the second direction C. The dimension of the first card slot 1110 extending along the second direction C is greater than that of the second card slot 1120 extending along the second direction C. The dimension of the first elastic support piece 3 extending along the second direction C is greater than that of the second elastic support piece 4 extending along the second direction C.

[0056] In this embodiment, by making the dimension of the first sheath part 111 extending along the second direction C greater than that of the second sheath part 112 extending along the second direction C, it is convenient for the arrangement of the water blocking part 12 and avoids the water blocking part 12 being too close to the wiper rubber strip 2 in the second direction C, which may affect the normal use of the wiper rubber strip 2. Secondly, the dimension of the first card slot 1110 extending along the second direction C is greater than that of the second card slot 1120 extending along the second direction C, and the dimension of the first elastic support piece 3 extending along the second direction C is greater than that of the second elastic support piece 4 extending along the second direction C, which can better support the first sheath part 111 and the wiper rubber strip 2 and improve the stability.

[0057] Refer to Figure 1 and Figure 2 As shown, the above-mentioned rubber strip base 21 includes a first base part 213 and a second base part 214 connected to each other in the first direction B; the first base part 213 is arranged in the installation groove 110, and the second base part 214 is connected to the rubber strip body 22 on one side away from the first base part 213 in the first direction B, and the second base part 214 and the rubber strip body 22 are arranged outside the installation groove 110; the water blocking part 12 is arranged opposite and spaced from the second base part 214 in the second direction C.

[0058] That is to say, the water blocking part 12 in this embodiment is not arranged opposite to the rubber strip body 22 in the second direction C. The reason for this arrangement is that the rubber strip body 22 itself will undergo elastic deformation during operation, and its dimension in the first direction B will be smaller. If the water blocking part 12 is arranged opposite to the rubber strip body 22 in the second direction C, there is a risk that the water blocking part 12 will contact the vehicle glass, causing scratching of the vehicle glass.

[0059] In one embodiment, refer to Figure 1 and Figure 2As shown, the end of the water-blocking part 12 away from the sheath body 11 is configured as a bent end 100. The end of the rubber strip body 22 away from the rubber strip base 21 in the first direction B is configured as a first end 200. The end of the rubber strip base 21 away from the rubber strip body 22 in the first direction B is configured as a second end 300. The dimension between the bent end 100 and the first end 200 in the first direction B is between 3 mm and 5 mm; the dimension between the bent end 100 and the second end 300 in the first direction B is between 6 mm and 8 mm. Additionally, the dimension between the bent end 100 and the first end 200 in the second direction C is between 11 mm and 15 mm.

[0060] For example, as shown in Figure 2 The dimension between the bent end 100 and the first end 200 in the first direction B can be 3 mm, can be 4 mm, or can be 5 mm. The present disclosure does not limit the specific dimension; the dimension between the bent end 100 and the second end 300 in the first direction B can be 6 mm, can be 7 mm, or can be 8 mm. The present disclosure does not limit the specific dimension. The dimension between the bent end 100 and the first end 200 in the second direction C can be 11 mm, can be 13 mm, or can be 15 mm. The present disclosure does not limit the specific dimension; additionally, it should be noted that the above dimension limitation is based on the condition that the rubber strip body 22 does not undergo elastic deformation.

[0061] In addition, the above-mentioned sheath body 11 and water-blocking part 12 can be configured as an integrally formed structure. For example, the sheath body 11 and water-blocking part 12 can be integrally injection-molded using a plastic material.

[0062] The present disclosure also provides a windshield wiper, which includes the above-mentioned wiper blade.

[0063] The present disclosure further provides a vehicle, which includes the above-mentioned windshield wiper. Among them, the water-blocking part 12 is bent and connected to the sheath body 11 and is close to one side of the vehicle A-pillar. The above-mentioned water-blocking part 12 can be provided only on the wiper blade opposite to the driver's position of the vehicle, reducing the coverage area of rainwater in the driver's side window vision area and improving the driving safety on rainy days. Or, the above-mentioned water-blocking part 12 can also be provided on both wiper blades at the front windshield. The present disclosure does not limit this.

[0064] Those skilled in the art will readily think of other embodiments of the present disclosure after considering the specification and practicing the present disclosure. This application aims to cover any variations, uses, or adaptive changes of the present disclosure, which follow the general principles of the present disclosure and include common general knowledge or conventional technical means in the technical field not disclosed in the present disclosure.
