Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of windshield wiper accessories, specifically a new type of windshield wiper rubber strip. Background Technology
[0002] There are several problems with wiper blades on the market. In terms of materials, traditional wiper blades mostly use natural rubber, which undergoes significant changes in hardness under heat and low temperature conditions. At high temperatures, it softens, resulting in weak wiping; at low temperatures, it hardens, causing vibrations and severely affecting wiping performance. This impairs the driver's visibility and increases driving safety hazards.
[0003] According to publication number CN217623477U, this new type of wiper blade is effective in preventing debris from getting stuck in the gaps, thus improving the protection of the windshield during wiper cleaning. However, the existing wiper blade structure is not strong enough and is prone to deformation under long-term use or when facing complex wiping environments.
[0004] Therefore, in order to address the existing shortcomings, we conducted research and improvements and proposed a new type of wiper blade. Utility Model Content
[0005] The purpose of this invention is to provide a novel wiper blade to solve the problems mentioned in the background section.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel wiper blade, comprising: a blade body, wherein the blade body is provided with a structural reinforcement area and an installation engaging end, the wiping blade portion of the blade body is provided with a blade reinforcing rib, a blade buffer groove and a blade sealing cavity, the connection portion between the wiping blade and the blade body is provided with a connection support rib, and the installation adapter end of the blade body is provided with an installation positioning boss.
[0007] Furthermore, the structural reinforcement area is a multi-layer composite structure, consisting of alternating layers of high-strength rubber material and fiber-reinforced material, which enhances the overall structural strength of the rubber strip body.
[0008] Furthermore, the mounting engagement end has a serrated structure with a tooth angle of 45°-60°. This structure can tightly engage with the wiper frame to prevent the rubber strip from shifting during wiping.
[0009] Furthermore, the blade reinforcement rib has a wave-shaped structure with a wave crest height of 0.5mm-1mm and a wave crest spacing of 1mm-2mm, which effectively improves the strength and wear resistance of the scraping blade.
[0010] Furthermore, the depth of the blade edge buffer groove is 0.3mm-0.5mm, the width is 1mm-3mm, and the groove is filled with elastic buffer material.
[0011] Furthermore, the mounting and positioning boss is cylindrical, with a height of 1mm-2mm and a diameter of 2mm-4mm, which allows it to accurately mate with the positioning holes on the windshield wiper during installation, ensuring the precision of the rubber strip installation position.
[0012] Furthermore, the thickness of the connecting support rib is 0.8mm-1.2mm, and the length is 1 / 3-1 / 2 of the length of the connecting part of the adhesive strip body, providing stable support for the connection between the scraping blade and the adhesive strip body.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model enhances the strength of the blade edge by using reinforcing ribs to reduce wear; the blade edge buffer groove relieves pressure and ensures smooth shaving; the blade edge sealing cavity prevents impurities from entering and maintains the shaving effect. The connecting support ribs firmly connect the shaving blade edge to the rubber strip body, ensuring stable transmission of the shaving action. These structures work together to ensure that the rubber strip can effectively remove rainwater and debris from the windshield, providing the driver with a clear view;
[0015] 2. This utility model enhances the overall strength of the rubber strip through a composite structure in the reinforced area, making it less prone to deformation. The mounting positioning boss cooperates with the mounting locking end to ensure accurate and stable installation of the rubber strip without displacement. Simultaneously, the material selection avoids the influence of temperature on the rubber strip's performance, reducing vibration and scratching issues, extending the rubber strip's service life, and ensuring stable operation.

[0021] 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.
[0022] like Figures 1-4 As shown, a novel wiper blade includes: a blade body 1, a structural reinforcement area 2 and an installation engagement end 3 on the blade body 1, a blade edge reinforcing rib 4, a blade edge buffer groove 5 and a blade edge sealing cavity 6 on the wiping blade edge of the blade body 1, a connecting support rib 7 on the connection between the wiping blade edge and the blade body 1, and an installation positioning boss 8 on the installation adapter end of the blade body 1.
[0023] The rest, because the structural reinforcement zone 2 uses two layers of high-strength rubber material and one layer of fiber reinforcement material alternately laid, the high-strength rubber material is nitrile rubber, and the fiber reinforcement material is aramid fiber. This combination makes the structural reinforcement zone 2 not only enhance the overall strength of the rubber strip, but also have good aging resistance and extend the service life of the rubber strip.
[0024] The serrated structure of the mounting end 3 has a tooth angle of 50°. During installation, align the mounting end 3 of the rubber strip with the corresponding slot on the wiper frame and press gently. The serrated structure will then be tightly embedded in the slot, ensuring that the rubber strip will not loosen or shift during wiping.
[0025] The blade edge reinforcing rib 4 is designed in a wave shape with a peak height of 0.8mm and a peak spacing of 1.5mm. During the scraping process, the wave-shaped blade edge reinforcing rib 4 can effectively disperse the scraping force and reduce the local pressure between the blade edge and the glass, thereby improving the wear resistance of the blade edge. The blade edge buffer groove 5 has a depth of 0.4mm and a width of 2mm. The silicone filled in the groove can effectively buffer the pressure generated during scraping and reduce blade edge wear. The blade edge sealing cavity 6 adopts a special sealing process to ensure that external impurities cannot enter and keep the blade edge clean.
[0026] The connecting support rib 7 is 1mm thick and half the length of the connecting part of the rubber strip body. It effectively enhances the strength of the connection between the wiping blade and the rubber strip body 1, preventing the connection from breaking during long-term use. The mounting positioning boss 8 is cylindrical, 1.5mm high and 3mm in diameter, and fits precisely with the positioning hole on the wiper, further improving the accuracy of rubber strip installation.
[0027] The rest, since the main body of the rubber strip is 30 inches long and the width is increased to 8mm, are designed to meet the needs of large-area wiping.
[0028] At this point, the structural reinforcement zone 2 consists of three layers of high-strength rubber material and two layers of fiber reinforcement material. The high-strength rubber material is made of neoprene rubber, and the fiber reinforcement material is made of carbon fiber. This structure allows the rubber strip to maintain good structural strength and not easily deformed when facing harsh usage environments.
[0029] The serrated structure of the mounting end 3 has a tooth angle of 55°, and the length of the serrations is increased to 3mm compared to the version adapted for passenger cars. This makes the engagement between the rubber strip and the wiper frame of commercial vehicles more secure, ensuring that the rubber strip will not fall off or shift during long-term, high-intensity wiping.
[0030] In addition, the wave-shaped peak height of the blade reinforcement rib 4 is 1mm and the peak spacing is 2mm, which further improves the strength and wear resistance of the blade edge. The blade edge buffer groove 5 has a depth of 0.5mm and a width of 3mm. The groove is filled with highly elastic polyurethane material, which can better buffer the large pressure generated during scraping. The blade edge sealing cavity 6 increases the sealing space and adopts a double sealing design to effectively block dust, mud and other impurities, ensuring the cleanliness of the blade edge and the scraping effect.
[0031] The connecting support rib 7 is 1.2mm thick and 2 / 3 the length of the connecting part of the rubber strip body. It provides stronger support for the connection between the wiping blade and the rubber strip body 1, preventing the connection from being damaged due to excessive force. The mounting positioning boss 8 is 2mm high and 4mm in diameter, which matches the larger positioning hole on the commercial vehicle windshield wiper, ensuring that the rubber strip is installed in the correct position and guaranteeing the stability of the wiping effect.
[0032] Working principle: When using this new type of wiper blade, the main body 1 of the blade is the core component, which directly contacts the windshield and undertakes the main wiping task. The blade edge reinforcing rib 4 at the wiping edge enhances the strength of the blade edge, enabling it to effectively resist the friction between the blade and the glass during frequent wiping, making it less prone to wear and ensuring the stability of the wiping effect. The blade edge buffer groove 5 can relieve the pressure generated during wiping and prevent the blade edge from being damaged due to excessive pressure. The elastic material filled in the groove further absorbs the pressure, ensuring smooth and stable wiping action. The blade edge sealing cavity 6 effectively prevents external impurities from entering, keeps the blade edge clean, and provides a guarantee for good wiping effect.
[0033] Furthermore, the connecting support rib 7 is located at the connection between the scraping blade and the rubber strip body 1, which enhances the structural strength of the connection, prevents the connection from breaking during the scraping process, ensures that the scraping blade and the rubber strip body 1 are firmly connected, and enables the scraping action to be transmitted stably.
[0034] Among them, the structural reinforcement zone 2 is set on the rubber strip body 1, providing additional structural support for the entire rubber strip. Its multi-layer composite structure is made of alternating high-strength rubber material and fiber reinforcement material, which significantly improves the overall strength and stability of the rubber strip, enabling it to work normally in different environments and not easily deformed.
[0035] In addition, the mounting positioning boss 8 and the mounting engaging end 3 of the mounting adapter end play a key role. The mounting positioning boss 8 is cylindrical and precisely matches the positioning hole on the wiper to determine the installation position of the rubber strip, ensuring the accuracy of the installation. The mounting engaging end 3 has a serrated structure with a tooth angle between 45° and 60°, which can tightly engage with the wiper frame to prevent the rubber strip from shifting during operation and ensure that the rubber strip is firmly installed on the wiper.
[0036] The embodiments of this utility model are given for the purposes of illustration and description, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and to design various embodiments with various modifications suitable for a particular purpose.
