DETAILED DESCRIPTION
[0021] The utility model will be further described in detail in combination with the drawings.
[0022] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
[0023] This embodiment relates to a wiper strip device, referring to Figures 1-2 , including: a mounting portion 1, a connecting portion 2 and a scraper portion 3. Among them, the mounting portion 1 fixes the entire wiper rubber strip on the wiper arm to ensure its stability and reliability during use. The connecting portion 2 is connected to the lower side of the mounting portion 1, and serves as a transition part between the mounting portion 1 and the scraper portion 3, playing the role of transmitting pressure. At the same time, it can also adjust the angle of contact between the scraper portion 3 and the glass to ensure better fit. The scraper portion 3 is connected to the lower side of the connecting portion 2, and it is V-shaped. The V-shaped scraper portion 3 can adapt to glass surfaces with different curvatures, ensuring that the wiper can fit tightly to the glass throughout the entire range of motion, thereby improving the scraping effect. The scraper portion 3 includes: a main blade 31 and supporting blades symmetrically arranged on both sides of the main blade 31 and arranged in sequence from short to long close to the side of the main blade 31. The gradually increasing length of the support blades allows the wiper strip to adapt to a wider range of vehicle models and glass shapes, as well as to different wiper arm pressures, improving the product's versatility and adaptability. It also provides more even pressure distribution, avoiding localized wear and incomplete wiping caused by uneven pressure, further enhancing wiping effectiveness. Thus, when using this wiper strip device, the main blade 31 on the scraper portion 3 contacts the glass for up-and-down cleaning. As the pressure from the wiper arm increases, the short support blades closest to the main blade 31 first contact the glass, helping the main blade 31 initially adhere to the glass surface. The gradually increasing length of the support blades then sequentially contact the glass at varying pressures, ensuring that the main blade 31 adheres evenly to the glass across the entire pressure range. This allows the wiper strip device to adapt to different glass curvatures and arm pressures, while achieving excellent cleaning effectiveness. Furthermore, when wiping up and down, the wiper strip needs to rotate its wiping direction as it moves from the top to the bottom of the glass. The design of the support blades facilitates this rotation and minimizes the sound of the edge turning, achieving truly silent wiping.
[0024] In this embodiment, referring to Figure 1 The supporting blades include: a first supporting blade 32 , a second supporting blade 33 , a third supporting blade 34 , a fourth supporting blade 35 and a fifth supporting blade 36 .
[0025] The first supporting blade 32 is positioned adjacent to the main blade 31, the second supporting blade 33 is positioned above the first supporting blade 32, the third supporting blade 34 is positioned above the second supporting blade, the fourth supporting blade 35 is positioned above the third supporting blade 34, and the fifth supporting blade 36 is positioned above the fourth supporting blade 35. Thus, the plurality of supporting blades are sequentially arranged to form a V-shaped scraper portion 3. Conventional automotive wiper arm pressures range from 385 grams to 1200 grams, and the supporting blades of this wiper strip are adaptable to this range of arm pressures. When the wiper arm pressure is at its lowest, 385 grams, the wiper strip assembly is fully adaptable, with the main blade 31 primarily scraping and cleaning the glass. When the wiper arm pressure is between 440 grams and 675 grams, the first supporting blade 32 of this wiper strip assists the main blade 31 in scraping, ensuring a 45-degree angle when the wiper arm is scraping upwards and downwards, achieving a perfect scraping effect. Similarly, when the wiper arm pressure is between 680g and 840g, the first support blade 32 and the second support blade 33 both simultaneously assist the main blade 31 in scraping. Similarly, when the wiper arm pressure is between 880g and 1040g, the first support blade 32, the second support blade 33, and the third support blade 34 scrape. When the wiper arm pressure is between 1050g and 1200g, the first support blade 32, the second support blade 33, the third support blade 34, and the fourth support blade 35 scrape. At other times, when the pressure is extremely high, the five support blades scrape simultaneously to share the wiper pressure, maintaining normal use of the wiper. This makes the pressure distribution more even, avoids local wear and incomplete scraping caused by uneven pressure, and further improves the scraping effect. In other embodiments, the supporting blades can also be set to 8 or 10, etc., and the number of supporting blades is not specifically limited here.
[0026] In this embodiment, the width of the main edge 31 is 0.73 mm. This width ensures sufficient contact area for the main edge 31 to effectively scrape rainwater, while also preventing excessive width from increasing pressure on the glass and thereby scratching it. In other embodiments, the width of the main edge 31 may also be 0.60 mm, 0.65 mm, 0.70 mm, 0.75 mm, 0.80 mm, etc., as long as the width of the main edge 31 is within the range of 0.60-0.80 mm, and is not specifically limited here.
[0027] In the embodiment, the first and second support blades 32 and 33 are short and have a width of 0.25 mm, which first contact the glass and help the main blade 31 preliminarily adhere to the glass surface. The third and fourth support blades 34 and 35 are long and have a width of 0.30 mm, which further enhance the adhesion and stability of the main blade 31. The fifth support blade 36 is the longest and has a width of 0.31 mm, which provides additional support and stability and ensures that the main blade 31 can still uniformly adhere to the glass under maximum pressure. By gradually contacting the glass with the support blades of different widths, the pressure is uniformly distributed between the main blade 31 and the glass, avoiding the problems of local wear and incomplete scratching caused by uneven pressure. In other embodiments, the first and second support blades 32 and 33 can also have a width of 0.10 mm, 0.13 mm, 0.18 mm, 0.2 mm, 0.23 mm, 0.30 mm, etc., as long as the width of the first and second support blades 32 and 33 accounts for 34% of the width of the main blade 31 and the width is within the range of 0.10 mm-0.30 mm; the width of the third and fourth support blades 34 and 35 can also be 0.25 mm, 0.28 mm, 0.33 mm, 0.35 mm, etc., as long as the width of the third and fourth support blades 34 and 35 accounts for 41% of the width of the main blade 31 and the width is within the range of 0.25 mm-0.35 mm; the width of the fifth support blade 36 can also be 0.25 mm, 0.28 mm, 0.33 mm, 0.35 mm, 0.38 mm, 0.40 mm, etc., as long as the width of the fifth support blade 36 accounts for 42% of the width of the main blade 31 and the width is within the range of 0.25 mm-0.40 mm, which are not specifically limited above.
[0028] In the embodiment, referring to Figure 1 , the mounting portion 1 includes a mounting table 11, a connecting bone 12 connected to the lower side of the mounting table 11, a pressure receiving table 13 arranged on the lower side of the mounting table 11 and located on both sides of the connecting bone 12, and a blocking table 14 arranged on the lower side of the pressure receiving table 13 and located on both sides of the connecting bone 12, which ensures that the wiper strip device can maintain good scraping effect and stability under different pressures. The mounting groove 15 is formed between the pressure receiving table 13 and the mounting table 11, and the buffer groove 16 is formed between the blocking table 14 and the pressure receiving table 13, which not only improves the stability and buffer effect of the installation, but also prolongs the service life and reduces the noise. In other embodiments, the mounting portion 1 can also adopt other specific structures.
[0029] In the embodiment, the wiper strip device is made of silicone. In other embodiments, the wiper strip device can also be made of rubber or other materials.
[0030] The embodiment also relates to a wiper, which includes a main body frame (not shown) and the wiper strip device as described above assembled on the main body frame.
