Description

Technical Field

[0001] This invention relates to the field of locomotive window technology, and more particularly to an automatic lifting window for railway locomotives. Background Technology

[0002] The windows of railway locomotives are quite heavy. If they are opened or closed manually, it is not only time-consuming and laborious, but also often causes damage to the window frame due to uneven force. Therefore, railway locomotive windows are now developing towards electrification and intelligence.

[0003] However, in the existing technology, when the locomotive is in a power outage state due to a malfunction or accident, the internal mechanical lifting actuator of the electric window will interfere with the movement of the window, so that the people inside the vehicle cannot manually open or close the window. In an emergency, the window can only be broken with a window breaker. Obviously, this will not only cause certain economic losses, but also pose a great safety hazard to the lives of the people inside the vehicle. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic lifting window for railway locomotives. It solves the technical problem that in existing electric lifting windows, the window glass will jam after a power outage, making it impossible to manually raise or lower, which poses a significant safety hazard. This invention has the advantages of automatically raising and lowering the window when the locomotive is powered on, and automatically switching to manual raising and lowering mode after the locomotive is powered off, thus ensuring high safety.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic lifting window for railway locomotives, comprising a locomotive body, an installation window extending through the locomotive body, a rectangular cavity below the installation window, a movable baffle detachably installed on the outer side of the rectangular cavity, a window lifting mechanism movably installed inside the installation window, an anti-fog auxiliary mechanism inside the rectangular cavity, and an anti-pinch and moisture-proof mechanism inside the installation window. The window lifting mechanism includes soundproof glass movably installed inside the installation window, the lower end of the soundproof glass extending into the rectangular cavity and fixedly connected to an installation base, a fixed boss inside the rectangular cavity, a guide cylinder fixedly installed at the upper end of the fixed boss, the guide cylinder passing through the installation base and fixedly connected to the top wall of the rectangular cavity, and a drive mechanism movably installed at the upper end of the fixed boss. A lifting motor for rotating the lead screw is fixedly installed at the lower end of the fixed boss. An elliptical through groove is opened through the mounting base. The inner side wall of the elliptical through groove has symmetrical mounting slots. A lead screw nut is movably installed inside the elliptical through groove. The lead screw nut is slidably connected to the mounting slot. A magnetic push assembly is set between the lead screw nut and the inner wall of the mounting slot. A sponge roller is movably installed inside the mounting window. The end of the sponge roller is driven by a driven gear. A vertical toothed rod matching the driven gear is fixedly installed at the upper end of the mounting base. A fixed handle is set on the inner side of the upper end of the soundproof glass. When the drive screw rotates, it will move the mounting base upward through the cooperation between the lead screw nut and the drive screw, thereby completing the window raising operation. After the locomotive is powered off, the operator can pull the soundproof glass upward through the fixed handle to complete the manual window raising operation.

[0006] Preferably, the magnetic propulsion assembly includes an electromagnet fixedly installed inside the mounting slot, a permanent magnet fixedly installed on one side of the mounting slot with the lead screw nut, the electromagnet and the permanent magnet having the same magnetic poles on opposite sides, and a return spring fixedly connected between the lead screw nut and the inner wall of the mounting slot. When the locomotive is powered on, the two lead screw nuts will simultaneously contact the outside of the drive screw under the action of the electromagnet. After the locomotive is powered off, the two lead screw nuts will separate from the drive screw under the action of the return spring.

[0007] Preferably, the lead screw nut is semi-circular on the side facing the drive screw, and the lead screw nut and the drive screw are threaded together. When the two semi-circular lead screw nuts approach each other, they will form a complete circle and be threaded to the outside of the drive screw.

[0008] Preferably, the vertical rack extends into the interior of the mounting window and meshes with the driven gear. When the vertical rack moves upward with the mounting base, it will cause the sponge roller to rotate counterclockwise through its engagement with the driven gear. When the sponge roller rotates, it will wipe the inside of the soundproof glass.

[0009] Preferably, the anti-fog auxiliary mechanism includes a liquid-pushing cylinder fixedly installed at the upper end of a rectangular cavity. Liquid storage tanks can be detachably installed on both the left and right sides of the liquid-pushing cylinder. The upper end of the liquid-pushing cylinder is connected to a drain vertical pipe. The upper end of the drain vertical pipe extends into the interior of the installation window and is detachably fitted with a rectangular nozzle. A movable stopper is slidably connected inside the liquid-pushing cylinder. A movable push rod is fixedly connected to the lower end of the movable stopper. A return spring is sleeved on the outside of the movable push rod. When the movable stopper moves upward, the waterproofing agent inside the liquid-pushing cylinder will be sprayed outward through the drain vertical pipe and the rectangular nozzle. After the waterproofing agent is sprayed out, it will contact the outer surface of the soundproof glass, thereby preventing rainwater from adhering to the outside of the soundproof glass.

[0010] Preferably, the outer surface of the movable sliding plug is in close contact with the inner wall of the liquid storage cylinder, the lower end of the movable push rod extends to the bottom of the liquid pushing cylinder, and a solenoid valve is provided at the connection between the liquid storage cylinder and the liquid pushing cylinder. After the solenoid valve is opened, the waterproofing agent inside the liquid storage cylinder will enter the interior of the liquid pushing cylinder. Then, as the movable sliding plug moves upward, the waterproofing agent will enter the interior of the drain vertical pipe.

[0011] Preferably, the anti-pinch and moisture-proof mechanism includes symmetrically formed vertical grooves on the side walls inside the installation window. Anti-pinch components are installed inside the vertical grooves on the side walls. A water-removing scraper is detachably installed at the lower end of the installation window. The water-removing scraper contacts the outer surface of the soundproof glass. When rainwater flows down the soundproof glass, it will flow to the outside under the guidance of the water-removing scraper, thereby preventing rainwater from flowing into the rectangular cavity through the gap between the soundproof glass and the installation window.

[0012] Preferably, the anti-pinch assembly includes an infrared sensor that is detachably installed inside the vertical groove of the side wall. The infrared sensor is electrically connected to the lifting motor via a wire, and a battery pack that provides power to the infrared sensor is installed inside the vertical groove of the side wall.

[0013] By employing the above technical solution, the present invention provides an automatic lifting window for railway locomotives, which has at least the following beneficial effects:

[0014] 1. This invention, by setting up a window lifting mechanism, utilizes the cooperation between the drive screw and the mounting base to automatically raise and lower the soundproof glass when the locomotive is powered on, eliminating the need for manual pushing and pulling by the people inside the vehicle, saving time and effort. It can also automatically switch to manual lifting mode after the locomotive is powered off, without causing any movement interference to the window, ensuring that the people inside the vehicle can quickly complete the window lifting operation in an emergency, with high safety.

[0015] 2. This invention, by setting up a window lifting mechanism, utilizes the interaction between a vertical rack and a driven gear to automatically wipe and clean the inner surface of the soundproof glass during the upward movement of the mounting base, thereby ensuring that the soundproof glass is always clean without the need for manual wiping by people inside the vehicle. It has a high degree of automation and is easy to use.

[0016] 3. By setting up an anti-fog auxiliary mechanism, the present invention utilizes the cooperation between the liquid-push tube and the rectangular nozzle to automatically spray a certain amount of waterproofing agent onto the outside of the soundproof glass when it rains, thereby preventing rainwater from adhering to the outside of the soundproof glass and obstructing the view of the people inside the vehicle, which can effectively improve the driving experience of the people inside the vehicle.

[0017] 4. By setting up an anti-fog auxiliary mechanism, the present invention can automatically complete the quantitative addition and spraying of waterproofing agent by utilizing the cooperation between the liquid storage cylinder and the liquid pushing cylinder, eliminating the need for manual spraying by personnel inside the vehicle. This not only effectively improves the uniformity of waterproofing agent spraying but also avoids waste of waterproofing agent to a certain extent.

[0018] 5. By setting up an anti-pinch and moisture-proof mechanism, and utilizing the cooperation between the anti-pinch component and the water-removing scraper, if someone puts their hand in during the process of moving the soundproof glass upward, the lifting motor will immediately stop running, thereby avoiding the soundproof glass from causing injury to the people inside the vehicle, greatly improving the safety of use. Moreover, when it rains, the water-removing scraper will automatically guide the rainwater to the outside, preventing rainwater from entering the interior of the rectangular cavity, which can ensure the dryness of the interior of the rectangular cavity to a certain extent.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] according to Figures 1-5 As shown, an automatic lifting window for railway locomotives includes a locomotive body 1, an installation window 2 extending through the locomotive body 1, a rectangular cavity 3 below the installation window 2, a movable baffle 4 detachably installed on the outside of the rectangular cavity 3, a window lifting mechanism 5 movably installed inside the installation window 2, an anti-fog auxiliary mechanism 6 installed inside the rectangular cavity 3, and an anti-pinch and moisture-proof mechanism 7 installed inside the installation window 2.

[0032] Specifically, the window lifting mechanism 5 includes a soundproof glass 501 movably installed inside the mounting window 2. The lower end of the soundproof glass 501 extends into the interior of the rectangular cavity 3 and is fixedly connected to a mounting base 502. A fixing boss 503 is provided inside the rectangular cavity 3. A guide cylinder 504 is fixedly installed at the upper end of the fixing boss 503. The guide cylinder 504 passes through the mounting base 502 and is fixedly connected to the top wall of the rectangular cavity 3. A drive screw 505 is movably installed at the upper end of the fixing boss 503, and a drive screw 505 is fixedly installed at the lower end of the fixing boss 503. A lifting motor 506 is provided to rotate the drive screw 505. An elliptical through-slot 507 is provided through the mounting base 502. Symmetrical mounting slots 508 are provided inside the sidewall of the elliptical through-slot 507. A screw nut 509 is movably mounted inside the elliptical through-slot 507. The side of the screw nut 509 facing the drive screw 505 is semi-circular. The screw nut 509 and the drive screw 505 are threaded together. When the two semi-circular screw nuts 509 approach each other, they form a complete circle and are threadedly connected to the drive screw 505. Externally, a lead screw nut 509 is slidably connected to a mounting slot 508. A magnetic push assembly 510 is provided between the lead screw nut 509 and the inner wall of the mounting slot 508. A sponge roller 511 is movably mounted inside the mounting window 2. A driven gear 512 is drivenly connected to the end of the sponge roller 511. A vertical rack 513 matching the driven gear 512 is fixedly mounted on the upper end of the mounting base 502. The vertical rack 513 extends into the interior of the mounting window 2 and meshes with the driven gear 512. The vertical rack 513 follows the mounting base 502. When the 02 moves upward, it will cause the sponge roller 511 to rotate counterclockwise through the cooperation with the driven gear 512. When the sponge roller 511 rotates, it will wipe the inside of the soundproof glass 501. The inner side of the upper end of the soundproof glass 501 is provided with a fixed handle 514. When the drive screw 505 rotates, it will cause the mounting base 502 to move upward through the cooperation with the screw nut 509, thereby completing the window raising operation. After the locomotive is powered off, the staff can pull the soundproof glass 501 upward through the fixed handle 514 to complete the manual window raising operation.

[0033] More specifically, the magnetic propulsion assembly 510 includes an electromagnet fixedly installed inside the mounting slot 508, a permanent magnet fixedly installed on one side of the mounting slot 508 on the lead screw nut 509, the magnetic poles of the electromagnet and the permanent magnet on the opposite side are the same, and a return spring is fixedly connected between the lead screw nut 509 and the inner wall of the mounting slot 508. When the locomotive is powered on, the two lead screw nuts 509 will simultaneously contact the outside of the drive screw 505 under the action of the electromagnet. After the locomotive is powered off, the two lead screw nuts 509 will separate from the drive screw 505 under the action of the return spring.

[0034] In this embodiment, the locomotive is always powered on during operation. At this time, the electromagnet inside the magnetic propulsion assembly 510 will be energized and generate magnetism. Moreover, the magnetic poles of the electromagnet and the permanent magnet are the same on opposite sides. Therefore, the two semi-circular screw nuts 509 will surround the outside of the drive screw 505 together, and the screw nuts 509 and the drive screw 505 are threaded together.

[0035] Therefore, when occupants need to raise the window, they only need to manually press the up button on the side wall of the window 2 (which is electrically connected to the lifting motor 506 via a wire, not shown in the figure) to make the lifting motor 506 run in the forward direction. Then, the drive screw 505 will rotate around its own axis under the action of the lifting motor 506. When the drive screw 505 rotates, it will cause the mounting base 502 and the soundproof glass 501 to move upward synchronously, thereby completing the window raising operation.

[0036] When occupants need to lower the window, they simply need to manually press the lower button on the side wall of the window 2 to reverse the rotation of the lifting motor 506. Then, the drive screw 505 will rotate in the opposite direction under the action of the lifting motor 506, thereby causing the mounting base 502 and the soundproof glass 501 to move downward synchronously, completing the window lowering operation.

[0037] When the locomotive stops and the power is cut off inside the vehicle, the electromagnet inside the magnetic propulsion assembly 510 will lose its magnetism. Therefore, the two lead screw nuts 509 will disengage from the drive lead screw 505 under the tension of the return spring. At this time, the drive lead screw 505 will not interfere with the movement of the mounting base 502.

[0038] Therefore, when the locomotive is in a power-off state, the people inside the locomotive can pull the fixed handle 514 to move the soundproof glass 501 up and down, thereby completing the manual window raising and lowering operation.

[0039] Furthermore, when the mounting base 502 moves vertically upward, the vertical rack 513 will move upward synchronously. Since the vertical rack 513 is always in mesh with the driven gear 512, when the vertical rack 513 moves upward, the driven gear 512 will rotate counterclockwise. When the driven gear 512 rotates, the sponge roller 511 will rotate synchronously. Since the sponge roller 511 is in contact with the inner surface of the soundproof glass 501, the inner surface of the soundproof glass 501 will be wiped clean when the sponge roller 511 rotates, eliminating the need for manual cleaning by the people inside the vehicle.

[0040] This embodiment, by setting up a window lifting mechanism 5, utilizes the cooperation between the drive screw 505 and the mounting base 502 to automatically raise and lower the soundproof glass 501 when the locomotive is powered on, eliminating the need for manual pushing and pulling by passengers, saving time and effort. It also automatically switches to manual lifting mode after the locomotive is powered off, preventing any movement interference with the window and ensuring that passengers can quickly raise and lower the window in emergencies, ensuring high safety. Furthermore, by setting up the window lifting mechanism 5, this embodiment utilizes the cooperation between the vertical rack 513 and the driven gear 512 to automatically wipe and clean the inner surface of the soundproof glass 501 as the mounting base 502 moves upward, ensuring that the soundproof glass 501 is always clean, eliminating the need for manual wiping by passengers, resulting in a high degree of automation and ease of use.

[0041] Example 2

[0042] according to Figure 1 , Figures 6-8 As shown, based on Embodiment 1, the anti-fog auxiliary mechanism 6 includes a liquid-pushing cylinder 601 fixedly installed on the upper end of the rectangular cavity 3. Liquid storage tanks 602 are detachably installed on both the left and right sides of the liquid-pushing cylinder 601. A solenoid valve is provided at the connection between the liquid storage tanks 602 and the liquid-pushing cylinder 601. A drain vertical pipe 603 is connected to the upper end of the liquid-pushing cylinder 601. The upper end of the drain vertical pipe 603 extends into the interior of the installation window 2 and is detachably equipped with a rectangular nozzle 604. A movable sliding plug 605 is slidably connected inside the liquid-pushing cylinder 601. The outer surface of the movable sliding plug 605 is tightly fitted to the inner wall of the liquid storage tank 602. After the solenoid valve is opened, the liquid storage tank 602... 2. The waterproofing agent inside will enter the interior of the liquid-pushing cylinder 601. Next, as the movable sliding plug 605 moves upward, the waterproofing agent will enter the interior of the drain vertical pipe 603. The lower end of the movable sliding plug 605 is fixedly connected to a movable push rod 606, and the lower end of the movable push rod 606 extends to the bottom of the liquid-pushing cylinder 601. A return spring 607 is sleeved on the outside of the movable push rod 606. When the movable sliding plug 605 moves upward, the waterproofing agent inside the liquid-pushing cylinder 601 will be sprayed outward through the drain vertical pipe 603 and the rectangular nozzle 604. After the waterproofing agent is sprayed out, it will contact the outer surface of the soundproof glass 501, thereby preventing rainwater from adhering to the outside of the soundproof glass 501.

[0043] In this embodiment, when it rains, the people inside the vehicle will first turn on the solenoid valve to allow the waterproofing agent inside the liquid storage tank 602 to enter the liquid pushing cylinder 601, and then press the rise button to make the mounting base 502 and the soundproof glass 501 move upward synchronously.

[0044] If the car windows are already closed when it rains, you need to lower the windows first, then turn on the solenoid valve to allow the waterproofing agent to enter the liquid-push tube 601, and finally press the rise button to move the mounting base 502 and the soundproof glass 501 upwards simultaneously.

[0045] As the mounting base 502 moves upward, it will contact the movable push rod 606 and move it upward synchronously. When the movable push rod 606 moves upward, it will cause the movable slide plug 605 to move upward along the liquid-pushing cylinder 601, thereby causing the waterproofing agent inside the liquid-pushing cylinder 601 to be sprayed outward through the drain vertical pipe 603 and the rectangular nozzle 604. After the waterproofing agent is sprayed out, it will contact the outer surface of the soundproof glass 501, thereby preventing rainwater from adhering to the outside of the soundproof glass 501 and obstructing the view of the people inside the vehicle.

[0046] Since the solenoid valve is always in the closed state initially, there is no waterproofing agent inside the liquid-pushing tube 601. Therefore, when the mounting base 502 moves upward under normal conditions, the waterproofing agent will not be sprayed out.

[0047] This embodiment, by setting up an anti-fog auxiliary mechanism 6, utilizes the cooperation between the liquid-pushing cylinder 601 and the rectangular nozzle 604 to automatically spray a certain amount of waterproofing agent onto the outside of the soundproof glass 501 when it rains. This prevents rainwater from adhering to the outside of the soundproof glass 501 and obstructing the view of the occupants, effectively improving the driving experience. Moreover, by setting up the anti-fog auxiliary mechanism 6, this embodiment, through the cooperation between the liquid storage tank 602 and the liquid-pushing cylinder 601, can automatically complete the quantitative addition and spraying of the waterproofing agent, eliminating the need for manual spraying by the occupants. This effectively improves the uniformity of the waterproofing agent spraying and avoids waste of the waterproofing agent to a certain extent.

[0048] Example 3

[0049] according to Figure 1 and Figure 8 As shown, based on the above embodiment, the anti-pinch and moisture-proof mechanism 7 includes side wall vertical grooves 701 symmetrically opened inside the installation window 2. An anti-pinch component 702 is provided inside the side wall vertical grooves 701. A water-removing scraper 703 is detachably installed at the lower end of the installation window 2. The water-removing scraper 703 contacts the outer surface of the soundproof glass 501. When rainwater flows down along the soundproof glass 501, it will flow to the outside under the guidance of the water-removing scraper 703, thereby preventing rainwater from flowing into the interior of the rectangular cavity 3 through the gap between the soundproof glass 501 and the installation window 2.

[0050] Specifically, the anti-pinch assembly 702 includes an infrared sensor that is detachably installed inside the side wall vertical groove 701. The infrared sensor is electrically connected to the lifting motor 506 via a wire. The side wall vertical groove 701 is equipped with a battery pack that provides power to the infrared sensor.

[0051] In this embodiment, if a child accidentally puts their arm into the installation window 2 during the upward movement of the soundproof glass 501, the lifting motor 506 will immediately stop operating under the control of the infrared sensor, thereby achieving the anti-pinch function and effectively improving the safety of the device.

[0052] Furthermore, since the water removal scraper 703 always remains in contact with the outside of the soundproof glass 501 and is tilted outward, the water flowing downward along the soundproof glass 501 will flow outward under the guidance of the water removal scraper 703, and will not flow into the interior of the rectangular cavity 3 through the gap between the soundproof glass 501 and the installation window 2, thus ensuring the dryness of the interior of the rectangular cavity 3 to a certain extent.

[0053] This embodiment uses an anti-pinch and moisture-proof mechanism 7. By cooperating with the anti-pinch component 702 and the water-removing scraper 703, if someone puts their hand into the soundproof glass 501 during its upward movement, the lifting motor 506 will immediately stop operating, thereby preventing the soundproof glass 501 from causing injury to the people inside the vehicle and greatly improving safety. In addition, when it rains, the water-removing scraper 703 will automatically guide the rainwater to the outside, preventing rainwater from entering the interior of the rectangular cavity 3, which can ensure the dryness of the interior of the rectangular cavity 3 to a certain extent.

[0054] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0055] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
