Description

Technical Field

[0001] This utility model relates to the field of windshield wipers, specifically a high-strength windshield wiper. Background Technology

[0002] Windshield wipers are an important accessory installed on the windshield. Their function is to clear rain and snow from the car glass that obstruct the driver's view and prevent rain and snow from affecting the driver's visibility. High-strength windshield wipers are strong and can prevent damage to the wipers.

[0003] Existing high-strength windshield wipers, such as the lightweight, high-strength wiper connecting rod proposed in patent application number "CN202123207745.X", utilize structures such as the wiper blade, support rod, arc-shaped pressure plate, and X-axis rib. The connecting assembly connects to the connecting rod body. If dirt on the windshield creates significant frictional resistance, the connecting rod body, along with the connecting assembly and wiper assembly, will experience considerable resistance during movement. By fixing the Y-axis rib and X-axis rib to the outer edge of the support rod, X-axis and Y-axis support forces are formed between the connection points of the wiper assembly and the connecting assembly, effectively improving the strength between the wiper assembly, connecting assembly, and connecting rod body, and reducing the likelihood of breakage.

[0004] However, existing technology has defects. The sliding trajectory of the windshield wiper on the windshield of a car is arc-shaped, and the contact between the two ends of the wiper blade and the glass is poor, resulting in poor wiping effect at the two ends of the wiper blade. The actual wiping area is smaller than the sliding area of ​​the wiper blade. Therefore, a high-strength windshield wiper is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength windshield wiper to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A high-strength windshield wiper includes a drive arm, one end of which is rotatably connected to a mounting base, and the other end of which is rotatably mounted on a vehicle.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] A high-strength windshield wiper, such as Figures 1-6 As shown, the device includes a drive arm 1, one end of which is rotatably connected to a mounting base 3, and the other end is rotatably mounted on a vehicle. A main beam 2 is fixedly connected to the mounting base 3, and secondary beams 7 are fixedly connected to both ends of the main beam 2. A fixed arm 8 is mounted on both sets of secondary beams 7. A connecting seat 17 is fixedly connected to the middle of the fixed arm 8, and a scraper 9 is snapped onto the connecting seat 17. A scraper strip 15 is snapped onto the side of the scraper 9 away from the main beam 2. Elastic extrusion components are fixedly connected to both ends of the scraper 9, and the two sets of elastic extrusion components are slidably connected to both ends of the fixed arm 8.

[0026] The wiper is driven to slide by the drive arm 1. The mounting base 3 increases the installation strength between the drive arm 1 and the main beam 2 to prevent the wiper connection from breaking. The main beam 2 drives the wiper blade 9 to slide through two sets of secondary beams 7 and fixed arms 8. The wiper blade 9 is not easy to break when it is blocked and squeezed by external force. The wiper strip 15 at the lower end of the wiper blade 9 scrapes the glass to remove rain, snow and dust from the glass surface. The elastic squeezing component always squeezes both ends of the wiper blade 9. The wiper blade 9 has a certain elasticity, which makes the end of the wiper blade 9 bend closer to the glass, so that both ends of the wiper strip 15 can scrape the glass, thus improving the scraping effect.

[0027] like Figures 1-5 As shown, the elastic extrusion assembly includes a connecting column 12, which is fixedly connected to the end of the scraper 9. The fixed arm 8 has grooves 11 on both sides near the scraper 9, and a connecting port is opened through the groove 11. The end of the connecting column 12 is slidably connected to the connecting port. A spring 14 is sleeved on the side wall of the connecting column 12. One end of the spring 14 is fixedly connected to the scraper 9, and the other end abuts against the inner wall of the groove 11.

[0028] The spring 14 is always in a compressed state, constantly pressing the scraper 9, causing the end of the scraper 9 to bend, and the connecting post 12 to slide, so that the end of the scraper 9 fits against the glass. The groove 11 provides space for the spring 14 to engage, and the area of ​​the connection port is larger than that of the connecting post 12 to prevent the connecting post 12 from getting stuck.

[0029] like Figures 4-5 As shown, a fixing block 13 is fixedly connected to the end of the connecting post 12. The fixing block 13 is circular in shape, and the connection port is elliptical in shape. The diameter of the fixing block 13 is greater than the width of the connection port, the diameter of the fixing block 13 is greater than the diameter of the connecting post 12, and the diameter of the connecting post 12 is less than the length of the connection port.

[0030] The fixing block 13 cannot pass through the connection port. The fixing block 13 prevents the end of the connecting post 12 from detaching from the fixing arm 8. The connecting post 12 can tilt and slide along the long side of the fixing arm 8 in the connection port, but cannot tilt along the short side of the fixing arm 8, to prevent the connecting post 12 from tilting and becoming stuck due to the scraper 9 causing the connecting post 12 to slide.

[0031] like Figures 4-6 As shown, there are two sets of scraper blades 15 arranged in parallel. The lower end of the scraper 9 has two sets of mounting grooves. The two sets of mounting grooves are arranged in parallel. The upper ends of the two sets of scraper blades 15 are fixed with mounting strips 16. The two sets of mounting strips 16 are respectively snapped into the two sets of mounting grooves.

[0032] The two sets of scraper blades 15 can scrape the same area twice, making it cleaner. The scraper blades 15 are snapped into the mounting groove by the mounting strip 16, making them easy to disassemble and replace.

[0033] like Figures 1-2 As shown, both sets of the sub-beams 7 are U-shaped, and both ends of the scraper 9 are fitted with end caps 10 to prevent the scraper strips 15 from falling off.

[0034] The sub-beam 7 is fixed at multiple points to the fixed arm 8, which increases the strength of the wiper. The end cap 10 is detachable to prevent the wiper blade 15 from falling off.

[0035] like Figures 1-6 As shown, a diversion plate 4 is snapped onto the upper end of the main beam 2. The diversion plate 4 is shaped as an isosceles triangle. Side rails 5 are fixed to both sides of the lower end of the diversion plate 4. Slide rails 6 are provided on both sides of the main beam 2. The side rails 5 and slide rails 6 are snapped onto each other.

[0036] The diffuser 4 reduces the wind resistance experienced by the wipers during operation, preventing wind resistance from affecting the operation of the wipers. The diffuser 4 can be installed freely according to requirements.

[0037] The working principle of the high-strength windshield wiper provided by this utility model is as follows:

[0038] The wiper is driven to slide by the drive arm 1. The mounting base 3 increases the installation strength between the drive arm 1 and the main beam 2 to prevent the wiper connection from breaking. The main beam 2 drives the wiper blade 9 to slide through two sets of secondary beams 7 and fixed arms 8. The wiper blade 9 is not easy to break when it is blocked and squeezed by external force. The wiper strip 15 at the lower end of the wiper blade 9 scrapes the glass to remove rain, snow and dust from the glass surface. The elastic squeezing component always squeezes both ends of the wiper blade 9. The wiper blade 9 has a certain elasticity, which makes the end of the wiper blade 9 bend closer to the glass, so that both ends of the wiper strip 15 can scrape the glass, thus improving the scraping effect.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
