Currently, wipers are divided into two types: framed and frameless wipers, depending on their structure.

[0003] Most of the existing wipers currently have the problem that the wiper and water spray functions cannot be combined into one and the water splashing phenomenon is serious, which easily causes conflicts between pedestrians and affects the driver's driving vision.

[0004] Therefore, the present application provides a splash-proof automobile wiper assembly to solve the above-mentioned problems. Utility Model Content

[0005] The present application provides a splash-proof automobile wiper assembly, which aims to solve the problems mentioned in the background art that most of the existing wipers have the problem that the wiper and water spray functions cannot be combined into one and the splashing phenomenon is serious, which easily causes conflicts between pedestrians and affects the driver's driving vision.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solution: a splash-proof automobile wiper assembly, comprising a main rocker arm for transmission connection with an automobile wiper drive assembly, an auxiliary rocker arm movably mounted on one end of the main rocker arm away from the automobile wiper drive assembly and arranged to be in contact with the automobile windshield, and a scraper blade plugged into the auxiliary rocker arm for cleaning the automobile windshield, wherein the auxiliary rocker arm is provided with a synchronous water spray mechanism:

[0007] A grid frame is fixedly mounted on the auxiliary rocker arm, and a gusset plate is fixedly mounted inside the grid frame;

[0008] The synchronous water spray mechanism includes a fastener hinged on the main rocker arm at one end away from the automobile wiper drive assembly, two symmetrically arranged main supports are hinged in the fastener, and two auxiliary supports are hinged on the two main supports and are concentrically arranged and symmetrical with the fastener hinge. The two main supports and one end of the auxiliary support away from the fastener are fastened to the grille frame, and a water pipe that passes through the auxiliary support, the main support and the fastener in sequence and is connected to the automobile water supply end is fastened on the buckle plate. Two symmetrically arranged and U-shaped water spray pipes are fixedly installed on the water pipe, and a number of water spray holes are opened on the two water spray pipes. A number of clamps compatible with the water spray pipes are fastened on the buckle plate. In this way, when installing the wiper assembly, one side of the buckle plate on the auxiliary rocker arm is set against the windshield, the fasteners connect the main rocker arm and the auxiliary rocker arm, the main support and the auxiliary support press the auxiliary rocker arm tightly, and the water supply end of the car's water tank passes the clean water into the water spray pipe through the water pipe and sprays it out through the water spray hole, so that the main rocker arm drives the auxiliary rocker arm to scrape and clean the windshield while spraying water at the same time. The two functions are combined into one. Compared with the traditional separate design, it avoids the interference of the huge fan-shaped water surface sprayed by the original separate design on the driver's line of sight, and prevents the washing wastewater from splashing on passers-by near the car and drifting into the car.

[0009] Preferably, in order to connect the main support and the auxiliary support, the inner sidewalls of the fastener are fixedly provided with latching protrusions on two opposite surfaces, the main support is provided with a latching groove adapted to the latching protrusion near one end of the fastener, and the auxiliary support is fixedly provided with a hollow tube adapted to the latching groove near one end of the fastener. The latching protrusions extend from the outside of the main support into the latching groove and hollow tube in sequence. This ensures good tightness and a stable and reliable connection.

[0010] Preferably, to tighten the auxiliary rocker arm, an arch adapted to the grille frame is fixedly mounted on the end of the auxiliary support away from the fastener. The end of the main support away from the fastener is engaged with both ends of the top of the grille frame, and the arch is engaged with the center of the top of the grille frame. This makes the auxiliary rocker arm more stable and fits better with the windshield.

[0011] Preferably, in order to protect the water pipe, a mounting hole is provided on the main rocker arm, and the water pipe extends from one end near the fastener into the mounting hole, thereby reducing the probability of damage and improving service life and aesthetics.

[0012] Preferably, to facilitate the drainage of wastewater, the two spray pipes have different numbers of spray holes. The spray pipe on the side away from the main rocker arm extension has more spray holes than the other spray pipe, and the distribution density is higher. This allows more water to be sprayed above the wiper, resulting in a higher water pressure above than below, allowing the wastewater to flow smoothly to the bottom.

[0013] Preferably, to improve cleaning efficiency, the scraper bar is snapped onto the center of the bottom of the gusset plate. Two symmetrically arranged side scrapers are also snapped onto the bottom of the gusset plate on either side of the scraper bar. This provides a better scraping effect and higher cleaning efficiency. The side scrapers effectively prevent sprayed water from overflowing the auxiliary rocker arm without increasing friction with the windshield and thus burdening the motor.

[0014] Preferably, in order to fix the scraper strips and the side scraper strips, the outer walls of the scraper strips and the two side scraper strips are provided with limiting grooves, and the limiting grooves are inserted with expansion strips that abut against the inner wall of the gusset plate. This completes the installation and fixation of the scraper strips and the side scraper strips, and facilitates disassembly and replacement.

[0015] Preferably, in order to block water splashing, a water blocking sheet is fixedly mounted on the auxiliary rocker arm away from the extended end of the main rocker arm to avoid diffusion and reduce the impact on pedestrians.

[0016] The wiper assembly is configured such that one side of the gusset plate on the auxiliary rocker arm is fitted against the windshield, the fasteners connect the main rocker arm and the auxiliary rocker arm, the main support and the auxiliary support press the auxiliary rocker arm tightly, and the water supply end of the car's water tank passes clean water into the water spray pipe through the water pipe and sprays it out through the water spray hole, so that the main rocker arm drives the auxiliary rocker arm to scrape and clean the windshield while spraying water at the same time. The two functions are combined into one. Compared with the traditional separate design, this avoids the interference of the huge fan-shaped water surface sprayed by the original separate design on the driver's line of sight, and prevents the washing wastewater from splashing on passers-by near the car and drifting into the car.

[0017] In this wiper assembly, the water blocking plate is located at the end of the water spray pipe where the water spray holes are more densely packed. In actual installation, it is located on the upper half of the windshield. The water spray volume is large, and the water blocking plate can effectively prevent a large amount of water from overflowing through the end of the auxiliary rocker arm, avoiding diffusion and reducing the impact on pedestrians.

[0025] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] Example 1

[0027] This embodiment provides a splash-proof automobile wiper assembly, such as Figure 1-5 As shown, the wiper assembly includes a main rocker arm 1 for transmission connection with the automobile wiper drive assembly, an auxiliary rocker arm 2 movably mounted on one end of the main rocker arm 1 away from the automobile wiper drive assembly and arranged to be in contact with the automobile windshield, and a scraper strip 4 plugged into the auxiliary rocker arm 2 for cleaning the automobile windshield. A synchronous water spray mechanism 3 is provided on the auxiliary rocker arm 2:

[0028] A grid frame 21 is fixedly mounted on the auxiliary rocker arm 2, and a gusset plate 22 is fixedly mounted inside the grid frame 21;

[0029] The synchronous water spray mechanism 3 includes a fastener 31 hinged on the main rocker arm 1 at one end away from the automobile wiper drive assembly, and two symmetrically arranged main supports 33 are hinged in the fastener 31. Two auxiliary supports 35 are hinged on the two main supports 33, which are concentrically arranged and symmetrical with the hinge of the fastener 31. The two main supports 33 and the ends of the auxiliary supports 35 away from the fastener 31 are fastened to the grille frame 21, and a water pipe 38 is fastened on the buckle plate 22, which passes through the auxiliary support 35, the main support 33 and the fastener 31 in sequence and is connected to the water supply end of the automobile. Two symmetrically arranged and U-shaped water spray pipes 39 are fixedly installed on the water pipe 38, and a number of water spray holes 311 are opened on the two water spray pipes 39. A number of clamps 310 compatible with the water spray pipes 39 are fastened on the buckle plate 22.

[0030] When in use, the buckle plate 22 on the auxiliary rocker arm 2 is placed against the windshield, the fastener 31 connects the main rocker arm 1 and the auxiliary rocker arm 2, the main support 33 and the auxiliary support 35 press the auxiliary rocker arm 2, and the water supply end of the car tank passes the clean water into the water spray pipe 39 through the water pipe 38 and sprays it out through the water spray hole 311, so that the main rocker arm 1 drives the auxiliary rocker arm 2 to scrape and clean the windshield while spraying water at the same time. The functions of the two are combined into one. Compared with the traditional separate design, it avoids the interference of the huge fan-shaped water surface sprayed by the original separate design on the driver's line of sight, and at the same time prevents the washing sewage from splashing on passers-by near the car and drifting into the car.

[0031] Specifically, latching protrusions 32 are fixedly mounted on two opposing surfaces of the inner sidewall of the fastener 31. A latching slot 34 is formed on the main support 33 near one end of the fastener 31, which is compatible with the latching protrusion 32. A hollow tube 36 is fixedly mounted on the secondary support 35 near one end of the fastener 31, which is compatible with the latching slot 34. The latching protrusions 32 extend from the outside of the main support 33 into the latching slot 34 and hollow tube 36, respectively. During use, the inner diameter of the fastener 31 is larger than the outer diameter of the main support 33, which in turn is larger than the outer diameter of the secondary support 35. The two fasteners are fitted one over the other and connected via the latching protrusions 32 on the fastener 31, ensuring a tight, stable, and reliable connection.

[0032] More specifically, an arch 37 that mates with the grille frame 21 is fixedly mounted on the end of the secondary support 35 that is away from the fastener 31. The end of the primary support 33 that is away from the fastener 31 is engaged with both ends of the top of the grille frame 21, and the arch 37 is engaged with the center of the top of the grille frame 21. During use, the primary support 33 and the secondary support 35 secure the six points on the top of the grille frame 21, ensuring more even pressure distribution. This results in a more stable installation of the secondary rocker arm 2 and a better fit to the windshield.

[0033] Furthermore, a mounting hole 11 is formed on the main rocker arm 1, and a water pipe 38 extends from one end near the fastener 31 into the mounting hole 11. When in use, the water pipe 38 is passed through the mounting hole 11 from the connection of the car water tank, which reduces exposure, reduces the probability of damage, and improves service life and aesthetics.

[0034] Furthermore, the two water spray pipes 39 have different numbers of water spray holes 311. One of the water spray pipes 39, located farther from the extended end of the main rocker arm 1, has a greater number of water spray holes 311 than the other water spray pipe 39, and the distribution density is higher. During use, the water spray pipe 39 with a higher density of water spray holes 311 is located in the upper half of the windshield, while the water spray pipe 39 with a lower density of water spray holes 311 is located in the lower half of the windshield. This results in a higher amount of spray water being distributed in the upper half of the windshield and a lower amount in the lower half. The water in the upper half flows downward along the windshield surface, supplementing the water in the lower half during cleaning. This results in more water being sprayed above the wipers, resulting in a higher water pressure above and a higher pressure below, allowing the wastewater to flow smoothly downward.

[0035] A water-blocking plate 312 is fixedly mounted on the side of the auxiliary rocker arm 2, away from the extended end of the main rocker arm 1. When in use, the water-blocking plate 312 is located at the end of the water-spraying pipe 39 where the water-spraying holes 311 are densely packed. In actual installation, it is located on the upper half of the windshield. This provides a large amount of water spray, and the water-blocking plate 312 effectively blocks a large amount of water from overflowing through the end of the auxiliary rocker arm 2, preventing it from spreading and minimizing the impact on pedestrians.

[0036] Example 2

[0037] Unlike Example 1, when the scraper strip 4 is used alone, the scraping efficiency is low. Therefore, the scraper strip 4 is clamped to the center of the bottom of the pinch plate 22. Two symmetrically arranged side scrapers 41 are also clamped to the bottom of the pinch plate 22 on both sides of the scraper strip 4. When in use, the windshield is cleaned by the scraper strip 4 and the two side scrapers 41, resulting in better scraping effect and higher cleaning efficiency.

[0038] It should be noted that the height of the side scraper 41 is slightly lower than that of the center scraper 4, approximately 0.92 times that of the scraper 4, so that the side scraper 41 is close to the windshield but not in direct contact. In this way, the side scraper 41 can effectively prevent the sprayed water from overflowing the auxiliary rocker arm 2, but will not increase the friction with the windshield and cause an increase in the burden on the motor.

[0039] Furthermore, a limiting groove 42 is provided on the outer side walls of the scraper strip 4 and the two lateral scraper strips 41 , and an expansion strip 43 is inserted into the limiting groove 42 to abut against the inner side wall of the pinch plate 22 .

[0040] When in use, insert the expansion strip 43 into the limiting groove 42 on the scraper strip 4 and the two side scrapers 41, and then insert the scraper strip 4 and the two side scrapers 41 into the buckle plate 22 from the end of the auxiliary rocker arm 2 without the water blocking sheet 312, thereby completing the installation and fixation of the scraper strip 4 and the side scraper strip 41, making it easy to disassemble, assemble and replace.

[0041] It should be noted that the scraping strip 4 is harder than the lateral scraping strip 41 and has a better scraping effect. The lateral scraping strip 41 mainly plays the role of protecting the scraping strip 4 and assisting in scraping.

[0042] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
