Description

Technical Field

[0001] This utility model relates to the field of locomotive technology, and in particular to a side window structure for a locomotive driver's cab. Background Technology

[0002] As a key component of the locomotive driver's cab, the reliability of the side windows is crucial to the operational safety of the locomotive. However, traditional locomotive driver's cab side windows are prone to accidental opening due to vibrations during operation, severely interfering with the driver's vision. Furthermore, traditional side windows can only be fully open or fully closed, unable to be stably positioned according to the driver's actual needs, thus limiting the driver's flexibility in adjusting their field of vision. Secondly, wear and tear is common in the fixed frame and movable window structure of traditional side windows. Wear can cause the movable window to sway left and right, and its vertical sliding to become obstructed; more seriously, the debris generated by wear can further clog the sliding parts. In addition, because the cleaning structure of traditional side windows is fixed, cleaning can only be done by wiping during the opening and closing of the movable window. Over time, impurities easily accumulate on the cleaning structure, which can not only scratch the window surface and reduce cleaning effectiveness, but also increase maintenance costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a side window structure for a locomotive driver's cab that can effectively improve the convenience and stability of opening and closing the movable window of the locomotive driver's cab, as well as solve the problem of cleaning the movable window.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a side window structure for a locomotive driver's cab, including a fixed frame and a movable window slidably disposed inside the fixed frame. The upper part of the fixed frame is provided with a locking component, which is used to lock or unlock the movable window. The lower part of the fixed frame is provided with a balance hovering component, which is used to control the movable window to hover at any position. The middle part of the fixed frame is provided with window surface cleaning components on both the inner and outer sides.

[0005] The window cleaning assembly includes a support base, a lead screw, a motor, a lifting frame, a sliding rod, and a wiping block.

[0007] Furthermore, the lower part of the fixed frame is provided with a frame-shaped mounting part, the balance suspension component is located in the mounting part, a vertical guide rail is provided on the inner wall of one side of the mounting part, a slider is slidably mounted on the guide rail, the slider is connected to the bottom of the movable window, a movable pulley is provided inside the slider that can slide horizontally along it, a long connecting rod is fixedly connected to the movable pulley, and the other end of the long connecting rod is fixedly connected to a first spring through a mounting plate, the first spring is fixed at the end of the guide rail away from the slider.

[0008] Furthermore, the mounting plate is fixed to the long connecting rod by long bolts.

[0009] Furthermore, the guide rail is made of metal.

[0010] Furthermore, the wiping block is detachably connected to the fixing plate via a magnet.

[0011] Furthermore, the second magnet is a long bar magnet with the same length as the wiping block.

[0012] Based on the above technical solution, the beneficial effects of this utility model are:

[0013] 1. This utility model's window cleaning component is designed to achieve automated cleaning.

[0025] like Figure 1-4 As shown, a side window structure for a locomotive driver's cab includes a fixed frame 1 and a movable window 2 that is slidably disposed inside the fixed frame 1. The upper part of the fixed frame 1 is provided with a locking component for locking or unlocking the movable window 2. The lower part of the fixed frame 1 is provided with a balance hovering component for controlling the movable window 2 to hover at any position. The middle part of the fixed frame 1 is provided with window cleaning components 5 on both the inner and outer sides.

[0026] The locking assembly includes a handle-shaped locking stop 33 located at the upper middle position of the fixed frame 1 and a locking shaft 32 at the top of the movable window 2. A movable handle 31 is connected to the locking shaft 32. The locking shaft 32 and the locking stop 33 cooperate to lock or unlock the movable window 2.

[0027] The locking components are simple, durable, highly reliable, and have a low failure rate. The rigid mechanical lock effectively resists strong vibrations and wind pressure during locomotive operation, preventing the operable windows from accidentally shaking or opening, thus ensuring driving safety. The handle-shaped lock stop design facilitates the hooking and releasing of the lock shaft. Combined with the movable handle, the unlocking and locking actions are clear and can be completed with one hand.

[0028] The fixed frame 1 has a frame-shaped mounting part 11 at its lower part. The balance suspension component is located in the mounting part 11. A vertical metal guide rail 42 is provided on the inner wall of one side of the mounting part 11. A slider 41 is slidably mounted on the guide rail 42. The slider 41 is connected to the bottom of the movable window 2. A moving track 44 is provided inside the slider 41. A movable pulley 43 is slidably mounted inside the moving track 44. The movable pulley can slide left and right in the horizontal direction within the moving track 44. A long connecting rod 45 is fixedly connected to the movable pulley 43. The other end of the long connecting rod 45 is fixedly connected to the first spring 46 through a mounting plate 47. The mounting plate 47 and the long connecting rod 45 are fixed by a long bolt 48. The first spring 46 is fixed at the end of the guide rail 42 away from the slider 41.

[0029] The balanced hovering component is designed to precisely balance the weight of the sliding window, allowing users to easily release it at any height during operation and achieve stable hovering. This provides users with a stable and reliable field of vision, improves operational smoothness, and significantly reduces operator fatigue, effectively lowering maintenance costs and repair frequency. The spring's cushioning effect makes the sliding window move more smoothly when opening or closing heavily or when accidentally released, reducing impact noise and component wear, and extending the window's lifespan.

[0030] The window cleaning assembly includes a support base 51, a lead screw 52, ​​a motor 53, a lifting frame 54, a sliding rod 55, and a wiping block 513. The support bases 51 are fixedly mounted on a fixed frame 1 on one side at intervals. The lead screw 52 is mounted between the support bases 51, and the motor 53 drives the lead screw 52 to rotate. The sliding rod 55 is fixed to the fixed frame 1 on the opposite side of the lead screw 52 and is arranged parallel to the lead screw 52. One end of the lifting frame 54 is spirally sleeved on the lead screw 52, ​​and the other end is slidably mounted on the sliding rod 55. The lifting frame 54 has multiple mounting slots 56, each containing an oil reservoir. The oil storage cylinder 57 has a piston rod 59 slidably disposed inside it via a piston 58, and a second spring 510 is provided between the oil storage cylinder 57 and the piston rod 59. A fixing plate 511 is provided at the end of the piston rod 59 away from the lifting frame 54. A plurality of first magnets 512 are embedded in the fixing plate 511. A second magnet 514 is provided on one side of the wiping block 513, which magnetically engages with the first magnets 512. The wiping block 513 is detachably connected to the fixing plate 511 via the magnet. The second magnet 514 is a long bar magnet with the same length as the wiping block 513.

[0031] The window cleaning unit is designed for automated cleaning, allowing users to initiate the cleaning program with a single button from the cab, eliminating the need to manually wipe the windows from outside. This significantly improves cleaning efficiency and eliminates operational risks while the vehicle is in motion. The cleaning unit also adaptively conforms to the glass surface, ensuring a uniform cleaning effect and preventing damage to the glass from missed areas or excessive pressure in certain spots. The wiping pads are removable and replaceable or washable via magnets, improving maintenance convenience. The elongated magnets provide a larger adhesion area, ensuring the wiping pads remain firmly in place during cleaning and are not easily dislodged.

[0032] The working principle of this utility model is as follows:

[0033] When the user needs to receive the departure command, the user can grasp the movable handle 31 and rotate it clockwise, causing the movable handle 31 to drive the locking shaft 32 to disengage from the locking block 33, thereby unlocking the movable window 2. The user can then pull down the movable handle 31, causing the movable window 2 to move downwards. The slider 41 fixed to the bottom of the movable window 2 cooperates with the guide rail 42 on one side of the inner wall of the fixed frame 1, providing guidance for the movement of the movable window 2 and ensuring its stability during lifting and lowering. As the slider 41 descends along the guide rail 42, the movable pulley 43 moves to the left along the moving track 44 inside the slider 41, while the bottom of the long connecting rod 45 moves to the right. The long connecting rod 45, through the long bolt 48, drives the mounting plate 47 and the first spring 46 to stretch to the right. When the movable window 2 descends to the desired position, the user releases the movable handle 31, and the movable window 2 remains in that position under the balance of the tension of the first spring 46 and its own weight.

[0034] When closing the side window, the user can hold the movable handle 31 and lift it upwards. The slider 41 at the bottom of the movable window 2 moves upwards along the guide rail 42 on the inner wall of the fixed frame 1, causing the movable pulley 43 to move to the right along the moving track 44 inside the slider 41 fixed at the bottom of the movable window 2. Meanwhile, the bottom of the long connecting rod 45 moves to the left. The long connecting rod 45 drives the mounting plate 47 and the first spring 46 to retract to the left through the long bolt 48, thereby pushing the movable window 2 upwards. When the movable window 2 is raised to the desired position, the user releases the movable handle 31. The movable window 2 can be held in this position under the balance of the tension of the first spring 46 and its own weight. When the movable window 2 needs to be fully closed, the user can continue to lift the movable handle 31 upwards to reset it. Rotating the movable handle 31 causes the locking shaft 32 to engage with the locking stop 33, and the movable window 2 can be locked.

[0035] When the window surface of the movable window 2 needs cleaning, the user can activate the motor 53 in the window surface cleaning assembly 5 on both the inner and outer sides of the fixed frame 1. The motor 53 drives the lead screw 52 to rotate, converting the rotational motion of the lead screw 52 into the linear motion of the lifting frame 54, which in turn moves the lifting frame 54 up and down along the slide bar 55. The wiping block 513 on the lifting frame 54 wipes and cleans the window surface of the movable window 2 during the movement. When the wiping block 513 transitions from the fixed frame 1 to the window surface of the movable window 2, the extensibility of the second spring 510 allows the fixed plate 511 and the wiping block 513 to self-adjust. When the second spring 510 extends or retracts, it drives the piston 58 and piston rod 59 to move within the oil reservoir 57. The piston 58 divides the space within the oil reservoir 57 into two chambers. The hydraulic oil in the oil reservoir 57 flows repeatedly from one chamber to another through different small holes on the piston 58. The friction between the wall and the hydraulic oil, and the internal friction between the hydraulic oil molecules, hinder the flow of the hydraulic oil, thereby generating a damping force. This slows down the rebound speed of the second spring 510, ensuring the stability of the fixing plate 511 and the wiping block 513. This not only allows the wiping block 513 to fit tightly against the window surface when cleaning the movable window 2, but also allows the wiping block 513 to adapt to the thickness change between the movable window 2 and the fixing frame 1 with the extension and retraction of the second spring 510 when it is reset after cleaning. This allows the wiping block 513 to smoothly return to its initial position on the fixing frame 1, avoiding interference with the user's opening and closing of the movable window 2. If the user needs to replace the wiping block 513, since the wiping block 513 is magnetically connected to the fixing plate 511, the user can easily remove the wiping block 513 and then attach the second magnet 514 on one side of the new wiping block 513 to the first magnet on the fixing plate 511.

[0036] This utility model combines three core functions: safety assurance (locking component), convenient operation (balanced hovering component), and intelligent maintenance (window cleaning component), comprehensively improving the ergonomics, safety, and maintainability of the locomotive user compartment side window, and is especially suitable for the long-term, high-vibration, and dusty operating environment of locomotives.

[0037] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
