[0041] See also Figure 1-Figure 4 .
[0042] Some embodiments of the present application disclose a wiper device, including a wiper plate 3 and a wiper rod 2. The wiper plate 3 is used to wipe the glass. The wiper rod 2 is installed on the hydrogen energy rail working vehicle body 1 through a drive assembly. The wiper rod 2 is connected to the wiper plate 3. The drive assembly drives the wiper rod 2 to rotate, and the wiper rod 2 drives the wiper rod 2 to move to scrape the glass.
[0043] The wiper device disclosed in this solution also includes a lubrication assembly, including a water tank 5, a water pump 6, a water supply hose 7, a water spray pipe 8 and a nozzle 9. The water tank 5 is used to collect water discharged from the hydrogen energy rail vehicle body 1. The water pump 6 is used to pump the water in the water tank 5 to the water supply hose 7. The water supply hose 7 is connected to the water spray pipe 8, and the nozzle 9 is provided on the water spray pipe 8. When in use, when the wiper rod 2 is driven by the driving assembly to drive the wiper plate 3 to scrape the glass, the water pump 6 is turned on at the same time, and the water in the water tank 5 is sucked and sprayed onto the glass through the water supply hose 7, the water spray pipe 8 and the nozzle 9 in sequence. The wiper plate 3 sprays water onto the glass while swinging, so as to prevent the wiper rod 2 from directly scraping the dry glass and reduce the risk of glass scratches and wiper damage caused by the wipers scraping on the dry glass.
[0044] The water spray pipe 8 is arranged on the wiper rod 2, as shown in FIG. Figure 1 As shown, the water spray pipe 8 and the wiper plate 3 are respectively located at the two ends of the connection position between the wiper plate 3 and the wiper rod 2, and the nozzle 9 of the water spray pipe 8 is located on the upper surface of the wiper rod 2, ensuring that the wiper plate 3 scrapes the glass area after the water is sprayed by the nozzle 9.
[0045] When it rains, the lubrication component does not function, and when it does not rain, the lubrication component functions.
[0046] The water spray pipe 8 can be installed in the wiper rod 2 or outside the wiper rod 2.
[0047] In an embodiment where the water spray pipe 8 is installed in the wiper rod 2, a groove or cavity for installing the water spray pipe 8 can be defined in the wiper rod 2. In an embodiment where a groove is defined in the wiper rod 2, the groove is defined in the upper surface of the wiper rod 2, and the water spray pipe 8 is directly embedded in the groove. In an embodiment where a cavity is defined in the wiper rod 2, the water spray pipe 8 is inserted into the cavity, and a mounting hole for installing the spray head 9 is defined in the wiper rod 2.
[0048] In the embodiment where the water spray pipe 8 is installed outside the wiper rod 2, the water spray pipe 8 can be installed on the upper surface of the wiper rod 2 close to the glass, or it can be arranged side by side with the wiper rod 2 and installed on the surface of the wiper rod 2 in principle proportion.
[0049] The number of the water spray pipes 8 installed on the wiper rod 2 is not limited to one, and can be multiple.
[0050] The diameter of the wiper rod 2 gradually decreases from the end where the wiper rod 2 is connected to the drive assembly to the end where the wiper rod 2 is connected to the wiper plate 3. Accordingly, the shape of the water spray pipe 8 is adapted to the shape of the wiper rod 2. The diameter of the water spray pipe 8 gradually decreases from the end where the wiper rod 2 is connected to the drive assembly to the end where the wiper rod 2 is connected to the wiper plate 3. The size of the nozzle 9 also gradually decreases with the change in the diameter of the wiper rod 2. It should be noted that the water spray pipe 8 is provided with a plurality of nozzles 9, and the plurality of nozzles 9 are arranged along the length of the water spray pipe 8.
[0051] This design method, on the one hand, reduces the design difficulty of the nozzle 9 and the water spray pipe 8, and on the other hand, can ensure the spray pressure of the nozzle 9 and ensure that the spray distance of the nozzle 9 at each position is close.
[0052] The wiper rod 2 has the same diameter at all locations from one end where the wiper rod 2 is connected to the drive assembly to the end where the wiper rod 2 is connected to the wiper plate 3. Accordingly, the diameters of the water pipe 8 are also the same at all locations, and the sizes of the nozzles 9 installed at various locations on the water pipe 8 are also the same.
[0053] When the hydrogen-powered rail vehicle 1 is operating, its hydrogen fuel cell generates electricity through the reaction of hydrogen and oxygen. The vehicle 1 only produces water during operation. In this solution, a water storage tank 5 is connected to the vehicle's exhaust pipe via a drain pipe 4, collecting the water generated by the vehicle. This eliminates the need for a separate water source and simplifies the deployment of the wiper system.
[0054] Preferably, a filter is provided at the position where the water storage tank 5 is connected to the exhaust pipe, for filtering particulate impurities in the water to reduce the risk of clogging of the water supply hose 7, the water spray pipe 8 and the nozzle 9.
[0055] When the hydrogen energy rail operation vehicle body 1 is operating, water will be discharged continuously. In this solution, a drain pipe is set on the water tank 5. The installation height of the drain pipe on the water tank 5 is equal to the height of the highest water level in the water tank 5. When the water level in the water tank 5 reaches the highest water level, the water in the water tank 5 that exceeds the highest water level will be automatically discharged through the drain pipe. At this time, there is no need to set a valve or electronic control equipment, which reduces the design difficulty of the wiper device.
[0056] In some embodiments, a drain outlet is provided at a position of the water tank 5 corresponding to the highest water level, or the upper end of the water tank 5 is an open end, so that the water in the water tank 5 can be discharged automatically after being full.
[0057] Optionally, a minimum water level sensor is further provided on the water tank 5 and is in communication with the water pump 6 , so as to stop the water pump 6 from pumping water when the water level in the water tank 5 reaches the minimum water level.
[0058] In this solution, the water tank 5, the water pump 6 and the water supply hose 7 are all installed at the bottom of the hydrogen energy rail operation vehicle body 1, without occupying the internal space of the hydrogen energy rail operation vehicle body 1, which facilitates the arrangement of the lubrication components on the hydrogen energy rail operation vehicle body 1.
[0059] Optionally, the water tank 5 is a flat water tank to reduce the space occupied by the water tank 5 in the vertical direction and will not affect the height of the chassis of the hydrogen energy rail operation vehicle body 1 too much.
[0060] The water supply hose 7 is fixed to the bottom of the hydrogen energy rail operation vehicle body 1 by a clamp or a buckle to prevent the water supply hose 7 from swinging when the vehicle is running, reduce the wear of the water supply hose 7, and also prevent the water supply hose 7 from scratching against road obstacles when the vehicle is running.
[0061] When the hydrogen-powered rail vehicle 1 is used in a cold environment, there is a risk of ice forming in the water tank 5 and the water supply hose 7, which could cause the wiper device to malfunction. To address this issue, a drain valve can be provided on the water tank 5 and / or the water supply hose 7 to drain the water from the water tank 5 when the hydrogen-powered rail vehicle 1 stops operating. The drain valve can be a manual valve or a solenoid valve.
[0062] Furthermore, a heat-insulating layer may be provided on the water storage tank 5 and / or the water supply hose 7 to reduce heat exchange between the water storage tank 5 and / or the water supply hose 7 and the environment;
[0063] Furthermore, a heating device may be provided on the water tank 5 and / or the water supply hose 7 to melt the water tank 5 and / or the water supply hose 7 when the water tank 5 and / or the water supply hose 7 are frozen.
[0064] In some embodiments of the present scheme, the driving assembly includes a motor 15, a worm 14, a turbine 11, a rotating rod 12 and a rotating rod 13. The motor 15 transmits motion to the wiper rod 2 through the turbine 11, the worm 14, the rotating rod 12 and the rotating rod 13 to drive the wiper rod 2 to swing.
[0065] like Figure 3 As shown, the output shaft of the motor 15 is connected to the worm 14 to drive the worm 14 to rotate;
[0066] The worm 14 is engaged with the turbine 11 so that the worm 14 drives the turbine 11 to rotate;
[0067] The turbine 11 has a connecting shaft that is eccentrically arranged relative to the center of the turbine 11;
[0068] The rotating rod 12 is located between the turbine 11 and the rotating rod 13. The rotating rod 12 is a straight rod. One end of the rotating rod 12 is connected to the turbine 11 through a connecting shaft, and the other end of the rotating rod 12 is connected to the rotating rod 13.
[0069] The rotating rod 13 is Z-shaped as a whole and is perpendicular to the rotating rod 12. The rotating rod 13 includes a rotating shaft, a connecting rod and a rotating shaft. The rotating shaft is parallel to the axis of the rotating shaft, the connecting rod is perpendicular to the rotating shaft and the rotating shaft, and the two ends of the connecting rod in the length direction are respectively connected to the rotating shaft and the rotating shaft, wherein the rotating shaft is connected to the rotating rod 12, and the rotating shaft is connected to the wiper rod 2.
[0070] During operation, the motor 15 drives the worm 14 to rotate, the worm 14 drives the turbine 11 to rotate, the turbine 11 drives the connecting shaft to rotate, and the connecting shaft is rotatably connected to the rotating rod 12. Since the connecting shaft and the turbine 11 are eccentrically arranged, the rotating rod 12 pushes the rotating shaft to move forward and backward, and then the rotating shaft drives the rotating shaft to rotate through the connecting rod, so that the rotating shaft drives the wiper rod 2 to swing.
[0071] Specifically, by rotating the rotating rod 12, the rotating shaft is pushed forward to rotate half a circle, the rotating shaft drives the first end of the connecting rod to move forward, and the second end of the connecting rod to move backward, thereby driving the rotating shaft to rotate backward, and the rotating shaft drives the wiper rod 2 to swing backward; by rotating the rotating rod 12, the rotating shaft is pulled backward to rotate half a circle, the rotating shaft drives the first end of the connecting rod to move backward, and the second end of the connecting rod to move forward, thereby driving the rotating shaft to rotate forward, and the rotating shaft drives the wiper rod 2 to swing forward.
[0072] It should be noted here that the forward direction mentioned above is based on the angle in the figure, the right side of the rotating rod 12 is the front, and the left side of the rotating rod 12 is the back.
[0073] In this solution, the rotating rod 12 is rotatably connected to the rotating shaft, the rotating shaft is fixedly connected to the connecting rod, and the connecting rod is fixedly connected to the rotating shaft.
[0074] In this solution, the worm 14 cannot be driven by the rotation of the turbine 11, so that self-locking is formed, thereby ensuring the reliability of the operation of the wiper device.
[0075] The driving assembly disclosed in this solution also includes a function box 10, which provides an installation basis for the driving assembly. The function box 10 is installed on the hydrogen energy rail operation vehicle body 1.
[0076] like Figure 3 As shown, the functional box 10 is a two-half structure, which can facilitate the installation and maintenance of the parts in the functional box 10.
[0077] In this embodiment, the worm 14, turbine 11, rotating rod 12, and rotating rod 13 of the drive assembly are mounted within the function housing 10. A connecting shaft connected to the turbine 11 is located within the function housing 10 and is connected to the turbine 11 via a bearing. The motor 15 is located outside the function housing 10. The output end of the motor 15 passes through the function housing 10 and is connected to the worm 14. The second end of the rotating shaft of the rotating rod 13 passes through the function housing 10 and is connected to the wiper lever 2.
[0078] like Figure 1 and Figure 4 As shown, the function box 10 is installed on the hydrogen energy rail operation vehicle body 1 near the glass. In order to facilitate the connection between the water supply hose 7 and the water spray pipe 8, the water supply hose 7 can pass through the function box 10 and connect with the water spray pipe 8.
[0079] To protect the wiper rod 2 and wiper blade 3 from direct sunlight, the wiper device disclosed in this embodiment further includes a wiper guard 16. Optionally, the wiper guard 16 is perpendicular to the plane of the front windshield and extends forward from the hydrogen-powered rail vehicle body 1 to block sunlight. "Front" here refers to the forward direction of the hydrogen-powered rail vehicle body 1.
[0080] The wiper shield 16 can also shield rainwater and debris from the upper side and the front side of the wiper rod 2 and the wiper plate 3 .
[0081] The wiper guard 16 is connected to the hydrogen energy rail operation vehicle body 1 by bolts.
[0082] A headlight is fixed on the wiper baffle 16 , and a headlight 17 is also provided on the hydrogen energy rail operating vehicle body 1 .
[0083] like Figure 1As shown, the wiper shield 16 includes a horizontal plate and a curved plate. The horizontal plate is connected to the body of the hydrogen-powered rail vehicle 1, while the curved plate is connected to the horizontal plate. The end of the curved plate not connected to the horizontal plate is a free end. The width of the curved plate in a direction perpendicular to its length is greater than the width of the horizontal plate in a direction perpendicular to its length. The curved plate slopes downward from the end connected to the horizontal plate toward the free end, thereby diverting rainwater and impurities, thereby reducing their accumulation on the wiper shield 16.
[0084] Optionally, the size of the wiper guard 16 along the direction perpendicular to the forward direction of the hydrogen energy rail operation vehicle body 1 is close to the size of the front windshield along the direction perpendicular to the forward direction of the hydrogen energy rail operation vehicle body 1, so as to improve the protection effect of the wiper device.
[0085] The present solution also discloses a hydrogen energy rail working vehicle, comprising a wiper device, which is the wiper device described in any one of the above solutions.
[0086] Since the wiper device has the above-mentioned technical effects, the hydrogen-powered rail vehicle equipped with the wiper device also has the same technical effects, which will not be described in detail here.
[0087] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed, and is not intended to limit the present application. For those skilled in the art, various modifications and variations of the present application are possible. The scope of application involved in the present application is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the above-mentioned application concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.
