Technical Field
[0001] This utility model relates to the field of intelligent windshield wiper technology, specifically to an intelligent windshield wiper for railway locomotives. Background Technology
[0002] A windshield wiper is a tool used to clean the windshield of a vehicle to prevent rainwater and other debris from obstructing vision. The wiper is powered by an electric motor, which is the core of the entire wiper system. The quality requirements for wiper motors are quite high. They typically use DC permanent magnet motors, and the wiper motor mounted on the windshield is usually integrated with the worm gear mechanism. The worm gear mechanism reduces speed and increases torque, and its output shaft drives a four-bar linkage, which converts continuous rotary motion into a left-right oscillating motion.
[0003] For example, the single-glass windshield wiper for railway locomotives disclosed in the authorization announcement number CN217515126U includes a mounting plate, an elongated hole on the side of the mounting plate, a fixing head fixed at both ends of the mounting plate, a positioning plate on the upper side of the mounting plate, a wiper blade movably disposed in the elongated hole fixed on the side of the positioning plate, and a limiting plate constraining the positioning plate on the side of the fixing head.
[0004] Although it features brushes on both sides of the wiper blade, these brushes clean away dust and other small particles on the glass before the wiper blade cleans the glass, reducing the amount of dust adhering to the wiper blade and preventing dust from scratching the glass as the wiper blade swings. At the same time, the wiper blade is equipped with an elastic element that continuously pushes the wiper blade out, preventing wear and tear and gaps between the wiper blade and the glass after prolonged use. This ensures a tight fit between the wiper blade and the glass, improving the effectiveness of wiping rain and cleaning dust.
[0005] However, this does not solve the problem that existing smart wipers are generally not conducive to convenient reciprocating cleaning of railway locomotives, nor to convenient multi-position cleaning of railway locomotive glass, which affects the cleaning range of railway locomotive glass, makes it difficult for smart wipers to fit tightly and conveniently to railway locomotive glass, and makes it difficult to replace wiper blades easily, thus affecting the effectiveness of smart wipers in wiping rain and cleaning dust. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a smart windshield wiper for railway locomotives, comprising a support frame and a connecting frame. The connecting frame is mounted on the outer wall of the support frame. A rocker arm is movably mounted inside the support frame. A drive arm is movably mounted on the outer wall of the rocker arm.

A servo motor is mounted on the outer wall of the support frame away from the connecting frame. A worm gear is mounted on the output end of the servo motor. A rotating shaft is movably mounted inside the support frame on one side of the worm gear and is connected to the rocker arm. A worm wheel is fitted onto the surface of the rotating shaft near the worm gear and meshes with the worm gear. A drive shaft is mounted on the outer wall of the rocker arm near the drive arm and is movably connected to the drive arm via the drive shaft. A right transmission shaft is mounted on the outer wall of the drive arm near the limit arm and is movably connected to the limit arm via the right transmission shaft.
[0008] Preferably, a right drive arm is fitted onto the surface of the right drive shaft, and a right drive shaft is mounted on the outer wall of the right drive arm near the side of the right drive arm.
[0009] Preferably, the right power arm is movably connected to the connecting frame via a right power shaft, and the right power shaft is connected to the right transmission arm.
[0010] Preferably, a left drive shaft is movably mounted on the outer wall of the limiting arm on the side away from the right drive shaft, and a left power arm is fitted onto the surface of the left drive shaft.
[0011] Preferably, a left power shaft is installed on the outer wall of the left power arm near the left transmission arm, and the left power shaft is connected to the left transmission arm and movably connected to the connecting frame.
[0012] Preferably, each of the adjustment frames is equipped with a support shaft at its top, and the surface of the support shaft is movably fitted with a limit sleeve.
[0013] Preferably, each of the limiting sleeves has a limiting shaft installed on its outer wall, and each limiting shaft has a spring fitted on its surface. Each adjusting shaft on one side of the spring has an adjusting arm fitted on its surface, and the adjusting arm is slidably connected to the limiting shaft. One end of the spring is connected to the limiting shaft, and the other end of the spring is connected to the adjusting arm.
[0014] Preferably, fixing bolts are symmetrically installed on the outer wall of the scraper body near the limiting frame, and the fixing bolts extend to the surface of the limiting frame.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the intelligent wiper not only realizes convenient reciprocating cleaning of railway locomotives, but also facilitates convenient multi-position cleaning of railway locomotive glass, increases the cleaning range of railway locomotive glass, and facilitates convenient and tight contact of the intelligent wiper with railway locomotive glass, improves the effect of intelligent wiper in wiping rain and cleaning dust, and facilitates convenient replacement of wiper blades.
[0016] A servo motor drives a worm gear to rotate, which in turn drives a worm wheel. The worm wheel then drives a rotating shaft, which in turn rotates a rocker arm.

The connecting frame provides limiting support for the right drive arm, facilitating convenient reciprocating movement between the right and left drive arms. The right and left drive arms respectively drive the two sets of connecting arms to reciprocate. The connecting arms drive the adjusting frame, adjusting shaft, and limiting frame to reciprocate, facilitating convenient intelligent wiper operation on the railway locomotive by the two sets of limiting frames. This enables convenient reciprocating cleaning of the railway locomotive by the intelligent wipers, facilitating convenient multi-position cleaning of the railway locomotive glass, increasing the cleaning range of the railway locomotive glass, and improving the efficiency of cleaning the railway locomotive glass.
[0017] With the support of the adjusting frame on the support shaft, the movable support of the support shaft on the limiting sleeve, the support of the limiting sleeve on the limiting shaft, and the support of the limiting shaft on the spring, the spring elastically drives the adjusting arm to rotate around the adjusting shaft. The limiting shaft provides sliding support for the adjusting arm, which in turn drives the adjusting shaft to rotate elastically. The adjusting frame provides movable support for the adjusting shaft, which in turn drives the limiting frame and the scraper body to rotate elastically. This ensures a tight fit between the scraper body and the glass. When the scraper body needs to be replaced due to prolonged use, multiple sets of fixing bolts are manually rotated to secure it. The fixing bolt changes from a locked to a loose state on the wiper body, allowing manual removal of the wiper body. The limiting bracket provides sliding support for the wiper body, and a new set of wiper bodies is reinstalled on the surface of the limiting bracket. The fixing bolt is then manually rotated, changing the fixing bolt from a loose to a locked state on the wiper body, facilitating easy replacement of the wiper body. This achieves a convenient and tight fit between the smart wiper and the railway locomotive glass, improving the wiping effect of the smart wiper in cleaning rain and dust, and facilitating easy replacement of the wiper, thus enhancing the convenience of using and replacing the smart wiper.
