Technical Field
[0001] This invention relates to the field of automotive windshield wiper technology, and in particular to an intelligent sensor-based windshield wiper that adjusts the wiping angle. Background Technology
[0002] Car windshield wipers are important safety components installed on the front windshield, rear windshield, and even headlights of a car. They mainly consist of a wiper motor, linkage, rocker arm, and rubber blade. Driven by the motor, they swing back and forth, using rubber blades to remove rainwater, snowflakes, dust, insect remains, and stains from the glass surface, ensuring clear visibility for the driver.
[0003] Current conventional car windshield wipers generally suffer from limited functionality and adaptability. Most products can only achieve a fixed back-and-forth wiping motion, making it difficult to flexibly adjust the wiping angle according to the actual rainfall intensity. This results in poor cleaning performance in different rain scenarios and limits their practicality. At the same time, the wiper blades of existing wipers mostly adopt a fixed installation structure, which makes the disassembly and assembly process cumbersome and inconvenient. This not only increases the difficulty of replacing and maintaining the wiper blades, but also affects the user experience, making it difficult to meet the current development needs of intelligent, convenient, and highly practical automotive parts.
[0004] Therefore, this application provides a car windshield wiper with intelligent sensing and adjustment of the wiping angle to meet the needs. Summary of the Invention
[0005] The purpose of this invention is to solve the problems existing in the above-mentioned background art, and to propose an intelligent sensing and adjusting car windshield wiper.
[0006] The technical problem to be solved by the present invention is to provide an intelligent sensor-adjustable windshield wiper to solve the problems of existing intelligent sensor-adjustable windshield wipers.
[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a car windshield wiper with intelligent sensing and adjustment of the wiping angle, including a mounting plate, a driving mechanism being provided on the mounting plate, and an installation and removal mechanism being provided on the driving mechanism; The driving mechanism includes a connecting plate, a first shaft, a mounting rod, and a swing rod. The connecting plate is fixedly installed on the side of the mounting plate, the first shaft is fixedly installed on the connecting plate, the mounting rod is rotatably connected to the first shaft, and the swing rod is fixedly installed on one end of the mounting rod. The installation and removal mechanism includes a sleeve, a receiving plate, and a scraper. The sleeve is inserted into the swing rod, the receiving plate is fixedly installed on the sleeve, and the scraper is fixedly installed on the receiving plate.
[0008] Preferably, a first motor is fixedly mounted on the back of the mounting plate, and the shaft end of the first motor passes through the mounting plate and is fixedly mounted with a second shaft, the second shaft being cylindrical in shape.
[0009] Preferably, a rotating rod is fixedly installed at one end of the second shaft. The rotating rod is strip-shaped and has a first cavity. The first cavity is square-shaped, and a second motor is fixedly installed on the inner wall of the first cavity.
[0010] Preferably, a lead screw is fixedly installed on the shaft end of the second motor, one end of the lead screw is rotatably connected to the inner wall of the first cavity, and a slider is threaded onto the lead screw. The slider is square in shape. Two limit rods are fixedly installed on the inner wall of the first cavity. The two limit rods are symmetrically arranged about the lead screw, and the slider slides on the limit rods.
[0011] Preferably, a third shaft is fixedly mounted on the slider. The third shaft is cylindrical. A first connecting rod is rotatably connected to the third shaft. The first connecting rod is elongated. There are two mounting rods. A second connecting rod is rotatably connected between the two mounting rods. The second connecting rod is elongated. One end of the first connecting rod is rotatably connected to one end of the second connecting rod.
[0012] Preferably, the swing rod has a second cavity, which is square in shape. A sliding rod is fixedly installed on the inner wall of the second cavity. The sliding rod is square in shape and a limit plate is slidably provided on the sliding rod.
[0013] Preferably, a spring is fixedly installed on one side of the limiting plate, and a push rod and a plug are fixedly installed on the other side of the limiting plate. One end of the push rod and the plug both pass through the swing rod. The push rod is cylindrical, and the plug is square.
[0014] Preferably, the inner wall of the socket has a slot, and the slot is a square through groove. A method for using an intelligent sensor-adjustable windshield wiper to adjust the wiping angle, characterized by comprising the following methods: When the wipers are needed, the first motor fixedly mounted on the back of the mounting plate is activated. The shaft of the first motor rotates, which drives the second shaft that passes through the mounting plate and is fixedly mounted on its shaft end to rotate.
[0015] The rotation of the second shaft then drives the rotating rod fixedly installed at one end of it to rotate.
[0016] Scraper angle adjustment process When the rotating rod rotates, the second motor fixedly installed in the first cavity inside it starts, and the rotating shaft of the second motor drives the lead screw to rotate.
[0017] Because the lead screw is threaded with a slider, and the slider slides on two symmetrically arranged limit rods on both sides of the lead screw, the rotation of the lead screw will cause the slider to move in a straight line along the lead screw and the limit rods.
[0018] When the slider moves, it drives the third shaft fixedly mounted on it to move, and the third shaft drives the first connecting rod rotatably connected to it to move.
[0019] Because the two mounting rods are rotatably connected by the same second link, and one end of the first link is rotatably connected to one end of the second link, when the first link moves, it will drive the second link to move, which in turn will drive the two mounting rods to rotate around the first shaft. The first shaft is fixedly installed on the connecting plate, and the connecting plate is fixedly installed on the side of the mounting plate.
[0020] The rotation of the mounting rod causes the swing rod fixed at one end to swing, thereby realizing intelligent sensing and adjustment of the scraping angle.
[0021] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, a drive mechanism is provided to stably drive the wiper blade to achieve efficient reciprocating deflection motion, ensuring thorough cleaning of the glass surface. At the same time, the mechanism can automatically adjust the wiping angle of the wiper blade according to the actual rainfall, making the wiper operation more suitable for the needs of different rainfall scenarios, significantly improving the overall practicality and user experience of the car wipers.
[0022] The above solution, by incorporating an installation and removal mechanism, effectively simplifies the installation and removal process of the wiper blades, enabling quick assembly and disassembly without the need for complex tools. This greatly improves the convenience of wiper blade replacement, allowing users to replace, clean, and maintain the wiper blades in a timely manner according to usage, ensuring that the wipers are always in good working order and further enhancing the overall user experience and practicality of the wipers.

[0039] Working principle: When in use, the first motor 26 is started, which drives the second shaft 29 to rotate. The rotation of the second shaft 29 drives the rotating rod 27 to rotate. The rotating rod 27, in turn, drives the third shaft 214 to rotate in a circular motion via the first cavity 210, lead screw 211, and slider 212. The third shaft 214, in this circular motion, drives the second connecting rod 22 to move via the first connecting rod 24. The second connecting rod 22, in this movement, drives the mounting rods 23 on both sides to reciprocate around the first shaft 215. During this reciprocating motion, the mounting rods 23 drive the scraper 32 to reciprocate through the swing rod 25, sleeve 34, and receiving plate 31, thus cleaning the car windshield. When the sensor detects a change in rainfall, the controller activates the second motor 213. The second motor 213 drives the lead screw 211 to rotate. As the lead screw 211 rotates, it drives the slider 212 to slide linearly along the surface of the limit rod 28. As the slider 212 slides, it drives the third shaft 214 to move linearly, thereby adjusting the radius of the circular motion of the third shaft 214 and thus adjusting the reciprocating motion angle of the wiper blade 32. Through the above settings, the wiper blade 32 can be stably driven to achieve efficient reciprocating deflection motion, ensuring that the glass surface is cleaned thoroughly. At the same time, the wiping angle of the wiper blade 32 can be automatically adjusted according to the actual rainfall, making the wiper operation more suitable for the needs of different rainfall scenarios and significantly improving the overall practicality and user experience of the car wiper.
[0040] When it is necessary to disassemble the scraper 32, the push rods 36 on both sides can be pressed in opposite directions. The push rods 36 on both sides will drive the limiting plate 310 to slide in opposite directions along the inner wall of the second cavity 37. When the limiting plate 310 on both sides slides in opposite directions, it will compress the spring 39 and simultaneously drive the insert block 35 to move until one end of the insert block 35 leaves the slot 33. At this time, the sliding of the insert sleeve 34 can be released, and then the insert sleeve 34 can be slid out along the swing rod 25, thereby achieving the purpose of disassembling the scraper 32, which is convenient for replacing the scraper 32. Through the above settings, the installation and disassembly process of the scraper 32 can be effectively simplified, and the quick disassembly and assembly operation can be easily completed without the need for complicated tools. This greatly improves the convenience of replacing the scraper 32, and makes it convenient for users to replace, clean and maintain the scraper 32 in a timely manner according to the usage situation.
