[0002] Most existing rail locomotive driver's cab side windows are mechanical side windows. These windows are typically locked by a locking handle at the top of the movable window or an eccentric handle on both sides of the fixed frame. The windows need to be opened and closed manually, which is laborious and increases the workload of the driver and crew.

[0003] In summary, to reduce the workload of drivers and passengers while ensuring the locking effect of electric side windows and improving their comfort, it is necessary to develop an electric side window to solve the problems existing in the current technology. Summary of the Invention

The locking mechanism includes a drive component and a sliding lock stop. The drive component is mounted on the fixed frame, and the sliding lock stop is slidably mounted on the fixed frame and connected to the output end of the drive component. The drive component drives the sliding lock stop to move between an unlocked position and a locked position. When the sliding lock stop is in the locked position, it rolls against the locking pin and abuts against the stop edge to lock the movable window assembly. When the sliding lock stop is in the unlocked position, it moves away from the locking pin to unlock the movable window assembly.

[0006] Optionally, the drive assembly includes a locking drive, a rotating shaft, and two cams. The locking drive is mounted on the fixed frame, the rotating shaft is rotatably mounted on the fixed frame, and the rotating shaft is connected to the output end of the locking drive. The two cams are spaced apart on the rotating shaft. The sliding lock is provided with two limiting blocks, which are located on both sides of the rotating shaft, and the two limiting blocks and the two cams are in rolling contact in a one-to-one correspondence.

[0010] Optionally, the driving assembly further includes a sensing assembly, which includes a micro switch and a signal plate. The micro switch includes a first switch body and a second switch body spaced apart on the fixed frame. The signal plate is disposed on the rotating shaft, and the signal plate is provided with a first contact block and a second contact block disposed opposite to each other. The first contact block contacts the first switch body to trigger a locking signal, and the second contact block contacts the second switch body to trigger an unlocking signal.

[0011] Optionally, the driving mechanism includes a mounting frame, a lead screw drive, a connecting seat, and a connecting rod assembly. The mounting frame is disposed on the fixed frame, the lead screw drive is disposed on the mounting frame, and the output shaft of the lead screw drive is threadedly connected to the connecting seat through a lead screw and a lead screw nut. The connecting seat is slidably disposed on the mounting frame in the horizontal direction. The connecting rod assembly includes a connecting rod body, a support rod, and a connecting rod. Both ends of the connecting rod body are rotatably connected to the mounting frame.

[0015] In the technical solution of this invention, the driving component in the locking mechanism drives the sliding lock stop away from the locking pin to unlock the movable window assembly. The driving mechanism drives the movable window body to slide downward along the fixed frame to open the movable window assembly. When closing the movable window assembly, the driving mechanism drives the movable window body to slide upward along the fixed frame until the top of the movable window body abuts against the fixed frame. At this time, the driving component in the locking mechanism drives the sliding lock stop closer to the locking pin until the sliding lock stop abuts against the edge of the locking pin to lock the movable window assembly. In this invention, the movable window assembly is opened or closed by driving the driving mechanism, thereby reducing the workload of the driver and passengers when manually operating the movable window assembly to open or close.

Detailed Implementation

[0024] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0025] See Figure 1 and Figure 2 An electric side window for a rail locomotive includes a fixed frame 10, a movable window assembly 20, a drive mechanism 30, and a locking mechanism 40. The movable window assembly 20 includes a movable window body 21 and a locking pin 22. The movable window body 21 is slidably mounted on the fixed frame 10, and the locking pin 22 is mounted on the movable window body 21. A retaining edge is provided at the end of the locking pin 22 away from the movable window body 21. The drive mechanism 30 is mounted on the fixed frame 10, and its output end is connected to the movable window body 21. The locking mechanism 40 includes a drive assembly 41. The sliding lock 42 and the drive component 41 are mounted on the fixed frame 10. The sliding lock 42 is slidably mounted on the fixed frame 10 and is connected to the output end of the drive component 41. The drive component 41 drives the sliding lock 42 to move between the unlocked position and the locked position. When the sliding lock 42 is in the locked position, the sliding lock 42 rolls into contact with the locking pin 22 and abuts against the stop edge to lock the movable window component 20. When the sliding lock 42 is in the unlocked position, the sliding lock 42 moves away from the locking pin 22 to unlock the movable window component 20.

[0026] In practical use, when the driver and passengers need to open the movable window assembly 20, the drive component 41 in the locking mechanism 40 drives the sliding lock stop 42 away from the locking pin 22 to unlock the movable window assembly 20. The drive mechanism 30 drives the movable window body 21 to slide downward along the fixed frame 10 to open the movable window assembly 20. When closing the movable window assembly 20, the drive mechanism 30 drives the movable window body 21 to slide upward along the fixed frame 10 until the top of the movable window body 21 abuts against the fixed frame 10. At this time, the drive component 41 in the locking mechanism 40 drives the sliding lock stop 42 to approach the locking pin 22 until the sliding lock stop 42 abuts against the edge of the locking pin 22 to lock the movable window assembly 20. In this invention, the movable window assembly 20 is opened or closed by the drive mechanism 30, thereby reducing the workload of the driver and passengers when manually operating the movable window assembly 20 to open or close. The locking mechanism 40 can effectively ensure the locking effect of the movable window assembly 20. The operation is simple and convenient, which is beneficial to improving the stability of the electric side window of the rail locomotive.

[0027] See Figure 2 The drive assembly 41 includes a locking drive 411, a rotating shaft 412, and two cams 413. The locking drive 411 is mounted on the fixed frame 10. The rotating shaft 412 is rotatably mounted on the fixed frame 10 and is connected to the output end of the locking drive 411. The two cams 413 are spaced apart on the rotating shaft 412. The sliding lock 42 is provided with two limit blocks 421. The two limit blocks 421 are located on both sides of the rotating shaft 412, and the two limit blocks 421 and the two cams 413 are in rolling contact in a one-to-one correspondence.

[0028] The two cams 413 are the first cam 413 and the second cam 413, respectively. When the movable window assembly 20 is unlocked, the locking drive 411 drives the rotating shaft 412 to rotate. The first cam 413 pushes the corresponding limit block 421, causing the sliding lock stop 42 to move from the locked position to the unlocked position. The sliding lock stop 42 moves away from the locking pin 22 to unlock the movable window assembly 20. At this time, the protruding end of the second cam 413 moves away from the corresponding limit block 421, thereby providing movement space for the sliding lock stop 42 to achieve the unlocking function; locking the movable window assembly 20. When the window assembly 20 is in operation, and the top of the movable window body 21 abuts against the fixed frame 10, the locking drive 411 drives the rotating shaft 412 to rotate in the opposite direction. The second cam 413 pushes the corresponding limiting block 421, causing the sliding lock stop 42 to move from the unlocked position to the locked position. At this time, the sliding lock stop 42 rolls into contact with the locking pin 22, and the edge of the sliding lock stop 42 abuts against the locking pin 22 to lock the movable window. At this time, the protruding end of the first cam 413 moves away from the corresponding limiting block 421, thereby providing movement space for the sliding lock stop 42. The drive assembly 41 achieves the unlocking and locking functions by driving the cam 413 to push the corresponding limiting block 421. The structure is simple, the operation is convenient, and it effectively saves manpower.

[0029] See Figure 2 , Figure 3 and Figure 4 In one embodiment, a groove 421a is formed at the contact point between the limiting block 421 and the cam 413, and the groove 421a matches the shape of the cam 413. When the movable window assembly 20 is in the locked state, the cam 413 engages in the groove 421a of the corresponding limiting block 421, thereby preventing external force disturbances or locomotive vibrations from causing the sliding lock stop 42 to disengage from the locked position, effectively improving the stability of the locking mechanism 40 and ensuring the locking effect of the movable window assembly 20.

[0030] In one embodiment, the sliding lock stop has an inclined surface 422 on the side near the locking pin 22, and the inclined surface 422 makes rolling contact with the locking pin 22. The movable window assembly 20 also includes an unlocking handle 23, which is rotatably mounted on the movable window body 21, and the unlocking handle 23 has the locking pin 22 on it. In the absence of power, the driver and passengers only need to manually rotate the unlocking handle 23 to make the locking pin 22 roll along the inclined surface 422 until the locking pin 22 disengages from the sliding lock stop 42 to unlock the movable window assembly 20. The movable window assembly 20 can then be manually pulled to move up or down. The inclined surface 422 provides a guiding effect for the locking pin 22, making it easier and less strenuous for the driver and passengers to rotate the unlocking handle 23.

[0031] In one embodiment, the locking mechanism 40 further includes a reset assembly 44, which includes a fixed base 441 and an elastic element 442. The fixed base 441 is disposed on the fixed frame 10, and the elastic element 442 is connected between the sliding lock stop 42 and the fixed base 441. When the sliding lock stop 42 is in the locked position, the elastic element 442 is in a stretched state, and the elastic element 442 applies a pulling force to the sliding lock stop 42 to make the sliding lock stop 42 fit tightly against the locking pin 22, thereby further improving the stability of the locking mechanism 40. When the sliding lock stop 42 is in the unlocked position, the elastic element 442 can also make the sliding lock stop 42 abut against the cam 413 to prevent the parts from shaking and causing wear.

[0032] In one embodiment, see Figure 1 The driving component 41 further includes a sensing component 43, which includes a micro switch 431 and a signal plate 432. The micro switch 431 includes a first switch body 431a and a second switch body 431b spaced apart on the fixed frame 10. The signal plate 432 is disposed on the rotating shaft 412, and has a first contact block 432a and a second contact block 432b arranged opposite to each other. The first contact block 432a contacts the first switch body 431a to trigger a locking signal, and the second contact block 432b contacts the second switch body 431b to trigger an unlocking signal. The micro switch 431 can monitor the real-time status of the locking mechanism 40, thereby enabling timely feedback of signals to the lower-level machine.

[0033] In one embodiment, see Figure 5 The driving mechanism 30 includes a mounting frame 31, a lead screw drive 32, a connecting seat 33, and a connecting rod assembly 34. The mounting frame 31 is disposed on the fixed frame 10. The lead screw drive 32 is disposed on the mounting frame 31, and the output shaft of the lead screw drive 32 is threadedly connected to the connecting seat 33 through a lead screw and a lead screw nut. The connecting seat 33 is slidably disposed on the mounting frame 31 in the horizontal direction. The connecting rod assembly 34 includes a connecting rod body 341, a support rod 342, and a connecting rod 343. Both ends of the connecting rod body 341 are rotatably connected to the mounting frame 31. One end of the support rod 342 is fixedly connected to a connecting rod adjacent to the fixed connecting rod in the connecting rod body 341 and rotates synchronously with it. The other end of the support rod 342 is slidably connected to the movable window body 21. The connecting rod 343 is rotatably connected between the connecting seat 33 and another connecting rod adjacent to the fixed connecting rod in the connecting rod body 341. When the main body 21 of the movable window rises, the lead screw drive 32 drives the connecting seat 33 to slide horizontally. The connecting seat 33 drives the connecting rod body 341 to rotate through the connecting rod 343. At the same time, the connecting rod body 341 drives the support rod 342 to lift the main body 21 of the movable window upward until the top of the main body 21 of the movable window abuts against the fixed frame 10 to close the movable window assembly 20. When the main body 21 of the movable window falls, the lead screw drive 32 drives the connecting seat 33 to slide in the opposite direction. The connecting seat 33 drives the connecting rod body 341 to rotate in the opposite direction through the connecting rod 343. At the same time, the connecting rod body 341 drives the support rod 342 to pull the main body 21 of the movable window downward until the bottom of the main body 21 abuts against the limiting block at the bottom of the fixed frame 10 to open the movable window assembly 20.

[0034] Specifically, the mounting frame 31 is provided with two spaced-apart fixed link seats. The link body 341 includes a first link, a second link, and a third link. The first link and the third link are rotatably connected to the two fixed link seats respectively, and the second link is rotatably connected between the first link and the third link. The first link is fixedly connected to the support rod 342, which can rotate synchronously with the first link. The third link is connected to the connecting seat 33 through the connecting rod 343. The link body 341 can ensure the flexibility of the drive mechanism 30 and enable the support rod 342 to lift up or pull down the movable window assembly 20.

[0035] In one embodiment, the drive mechanism 30 further includes an elastic component 35, which comprises a plurality of tension springs 351 spaced apart in a vertical direction. One end of each tension spring 351 is connected to a connecting seat 33, and the other end is connected to a mounting frame 31. The tension springs 351 provide support force at any position during the upward or downward stroke of the movable window body 21 to balance the weight of the movable window body 21, thereby reducing the load on the lead screw drive component 32, extending its service life, and reducing the workload of drivers and passengers when manually operating the side window to open or close. It also enables the movable window body 21 to be suspended at any position.

[0036] In one embodiment, the electric side window for the rail locomotive further includes a control mechanism 50, which includes a control unit, a first sensor 51 and a second sensor 52. The control unit is electrically connected to the drive mechanism 30 and the locking mechanism 40. The first sensor 51 is disposed on the top of the fixed frame 10 and is electrically connected to the control unit. The second sensor 52 is disposed on the bottom of the fixed frame 10 and is electrically connected to the control unit. The control unit 51 is also electrically connected to the micro switch 431. When the control unit 51 receives a command to open the movable window assembly 20, the control unit 51 controls the locking mechanism 40 to unlock the movable window assembly 20. After unlocking, the micro switch 431 sends a signal back to the control unit 51. The control unit 51 then controls the drive mechanism 30 to drive the movable window body 21 to slide downward along the fixed frame 10 until the second sensor 53 senses the movable window body 21 and sends a signal back to the control unit 51. The control unit 51 then controls the drive mechanism 30 to stop, and the movable window assembly 20 is open. When the control unit 51 receives a command to close the movable window assembly 20, after confirming that the locking mechanism 40 is in the unlocked state (if not, an unlocking operation needs to be performed), the control unit 51 drives the movable window body 21 to slide upward along the fixed frame 10 until the first sensor 52 senses the movable window body 21 and sends a signal back to the control unit 51. The control unit 51 then controls the drive mechanism 30 to stop and continues to control the locking mechanism 40 to lock the movable window assembly 20. At the same time, the locking signal of the micro switch 431 is triggered and sent back to the control center. The control mechanism 50 can monitor the status of the electric side windows of the rail locomotive in real time and provide feedback, thereby ensuring the normal use of the electric side windows of the rail locomotive and being able to detect faults in a timely manner to avoid safety accidents. The main body 21 of the movable window is also equipped with a safety contact edge, which has the effect of buffering and preventing hand pinching.

[0037] Furthermore, the present invention also provides a rail locomotive, which includes a body and an electrically operated side window for a rail locomotive as described above, with a fixed frame 10 disposed on the body. Since this rail locomotive includes the electrically operated side window for a rail locomotive as described above, it possesses all the beneficial effects of such a window, which will not be elaborated upon here.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
