Description

Technical Field

[0001] This invention relates to the field of human-computer interaction technology, specifically to a human-computer interaction device for the LKJ simulation training platform. Background Technology

[0002] LKJ (Lock-on-Land) is an important piece of equipment used to prevent trains from ignoring signals, causing speeding accidents, and assisting locomotive drivers in improving their operational skills. Currently, to improve the skill proficiency of railcar drivers or to train them, LKJ simulation training platforms are often used for LKJ simulation training. For example, trainees can conduct corresponding instrument control training on the LKJ simulation training platform. Among these, human-computer interaction equipment is an essential component of the LKJ simulation training platform, enabling trainees to interact with the platform.

[0003] Traditional human-computer interaction (HCI) devices typically consist of a housing with a display and control buttons. Since these devices usually lack sterilization capabilities and are mostly exposed, bacteria and fungi easily proliferate on the display and control buttons. As these organisms metabolize, they produce chemical byproducts that can corrode the display, reducing its sensitivity and causing irreversible damage. Furthermore, frequent operation of the display and control buttons during training leads to the accumulation of dust and bacteria on their surfaces. When different trainees use these devices, bacteria can spread, potentially transmitting infectious diseases. To address these issues, we propose the LKJ simulation training platform HCI device. Summary of the Invention

[0004] The purpose of this invention is to provide an LKJ simulation training platform human-computer interaction device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A human-computer interaction device for an LKJ simulation training platform, comprising:

[0007] A housing, one side of which is provided with a display device and control buttons; and,

[0008] A disinfection device, located on the housing, is used to disinfect the surfaces of the display device and control buttons;

[0009] The disinfection device includes:

[0010] An assembly base is embedded in the outer wall of the housing. A guide post is fixedly installed inside the assembly base. A slider is slidably installed at one end of the guide post. A tension spring is installed between the slider and the inner wall of the assembly base. A rotating shaft is inserted into the slider. The outer end of the rotating shaft is connected to a cleaning component for disinfecting the surface of the display device and control buttons. The cleaning component has a horizontal state and a vertical state. A pull rope flipping component connected to the cleaning component is provided on the slider. One end of the pull rope flipping component extends along the axis of the guide post to the other end of the guide post and is connected to a driving component. The driving component is used to drive the pull rope flipping component to rotate the cleaning component from the horizontal state to the vertical state. After rotation, the slider is then driven to move from one end of the guide post to the other end.

[0011] A further improvement is that the display device and control buttons are arranged sequentially from top to bottom on the outer wall of the housing, and the control buttons include a number of vertical columns of buttons arranged on the housing and equidistantly along the length of the display device.

[0012] A further improvement is that the driving component includes a toothed gear disposed on the inner wall of the mounting base and driven to rotate by a rotating device, a driven gear meshing on one side of the toothed gear, and the pull rope flipping component being wound around the outer wall of the shaft portion of the driven gear.

[0013] A further improvement is that the cleaning component includes:

[0014] A hollow base is fixedly sleeved on the outer wall of a rotating shaft at one end. The hollow base has a liquid storage chamber for storing disinfectant. One side of the hollow base has a corrosion-resistant sponge strip for contacting the display device and control buttons. The outer wall of the hollow base has several sets of seepage holes at equal intervals for wetting the corrosion-resistant sponge strip.

[0015] A further improvement is that the pull cord flipper includes:

[0016] A protrusion, horizontally fixed to the inner wall of the rotating shaft and located within the inner cavity of the slider, wherein a limiting block is provided in the inner cavity of the slider at a position below the rotating shaft; and...

[0017] A pull rope is connected to a protrusion at one end and passes through a limiting block and a slider at the other end before being wound around the outer wall of the shaft of the driven gear. The slider and the inner wall of the mounting base near the driving component are both provided with guides for guiding the pull rope.

[0018] When the pull rope drives the protrusion to engage with the limiting block, the rotating shaft drives the cleaning component to rotate from a horizontal state to a vertical state.

[0019] A further improvement is that the disinfection device further includes a locking element, which includes:

[0020] A drive gear is sleeved on the outer wall of the rotating shaft. A transverse rack meshes with the drive gear. The transverse rack is slidably disposed on the slider. A wedge-shaped block is provided on the transverse rack.

[0021] The elastic telescopic rod has one end fixed to the inner wall of the mounting base and the other end inserted into a hole opened on the slider. The axis of the hole is perpendicular to the axis of the rotation shaft. A ball is embedded in the movable end of the elastic telescopic rod. A connecting arm is provided on the outer wall of the movable end of the elastic telescopic rod. The connecting arm extends to the outside of the slider through a through-hole. A roller is provided on the connecting arm for the inclined side of the wedge block one to engage. The inclined side of the wedge block one faces the driving component.

[0022] Wedge block two is located on the inner wall of the slider on the side away from the driving component, and the hypotenuse of wedge block two is opposite to that of wedge block one;

[0023] When the rotating shaft drives the cleaning component to rotate to a vertical position, the drive gear drives the transverse rack, causing the wedge block one to push the connecting arm and drive the movable end of the elastic telescopic rod to disengage from the insertion hole. The wedge block two is used to drive the elastic telescopic rod back into the insertion hole.

[0024] A further improvement is that the cleaning component also includes:

[0025] A movable sealing plate is located on one inner wall of the liquid storage cavity. The movable sealing plate has several sets of two leakage holes for communicating with the first leakage hole. One end of the movable sealing plate penetrates the side wall of the liquid storage cavity and extends into a groove on the hollow seat. The end of the movable sealing plate located inside the liquid storage cavity is connected to the inner wall of the liquid storage cavity by a spring. The other end of the movable sealing plate has a rod corresponding to the rotation axis.

[0026] An eccentric disk is eccentrically and movably sleeved on the outer wall of the rotating shaft and connected to the slider through a bracket; the eccentric disk slides against the rod.

[0027] When the hollow seat is in a horizontal state, the first and second seepage holes are staggered. When the hollow seat is in a vertical state, the rod moves the movable sealing plate through the eccentric disc to make the first and second seepage holes correspond.

[0028] A further improvement is that it also includes a button locking device located inside the housing to prevent the button body from being pressed by the cleaning component;

[0029] The key locking device includes:

[0030] The mounting plate is located inside the housing. The mounting plate is equipped with a linkage driven by the cleaning component. The linkage is connected to several sets of locking components, and the several sets of locking components correspond one-to-one with several sets of button bodies.

[0031] The second locking element is used to lock the button body when the cleaning element rotates to a vertical position and moves from one end of the guide post to the other.

[0032] A further improvement is that the linkage includes:

[0033] A movable plate is parallel to and slidably mounted on the mounting plate, and both ends of the movable plate are provided with toothed segments;

[0034] A drive gear 1 is rotatably mounted on one end of a mounting plate via a rotating shaft 1 and meshes with a tooth segment. One end of the rotating shaft 1 movably passes through one side of the housing and is fixedly fitted with a toggle arm 1. The other end of the mounting plate movably passes through one side of the housing via a rotating shaft 2 and is fixedly fitted with a toggle arm 2. Both toggle arms 1 and 2 are actuated by a vertically positioned cleaning component, and toggle arms 1 and 2 are located at opposite ends of the length of the display device and control button, respectively. A rotating shaft 3 is meshed with the side of the rotating shaft 2 facing the rotating shaft 1 via a gear set. The outer wall of the rotating shaft 3 is fitted with a drive gear 2 that meshes with another tooth segment of the moving plate. A wedge block 3 is provided on the moving plate at a position corresponding to the locking component 2.

[0035] When the first toggle arm is tilted inward by the moving vertical cleaning component, the second toggle arm rotates from tilted to vertical, and at the same time, the third wedge block drives the second locking component to lock the button body; when the second vertical toggle arm is reset by the moving vertical cleaning component, the third wedge block drives the second locking component to unlock the button body.

[0036] A further improvement is that the second locking element includes:

[0037] A limiting plate is slidably disposed in a groove opened on the mounting plate. The groove extends along the width direction of the mounting plate. An elastic element is provided between the limiting plate and the inner wall of the groove. One end of the limiting plate slides against the inclined surface of the corresponding wedge block three. An clearance opening is provided on the limiting plate at the position corresponding to the button body for the button body to pass through.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] 1) The present invention is equipped with a disinfection device on the housing. The drive component drives the pull rope flipping component, which pulls the cleaning component from a horizontal state to a vertical state and then moves it from one end of the guide post to the other end. During the movement, the cleaning component disinfects the surface of the display device and control buttons, preventing dust and bacteria from damaging the display device and preventing the spread of bacteria between different trainees. At the same time, when the cleaning component moves to the other end of the guide post, it automatically rotates from a vertical state to a horizontal state and resets to the initial position at the guide post, so that the cleaning component can be automatically retracted without affecting the use of the human-computer interaction device.

[0040] 2) The present invention is also provided with a button locking device, which locks the button body in the control button when the cleaning part moves along the guide post after rotating to the vertical position, so that the cleaning button body is not easily pressed by mistake, thus preventing accidental control. When the cleaning part moves to the designated position, the button body is released to allow the button body to be used normally in the future. Attached Figure Description

[0051] 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. Example

[0052] Please see the appendix Figure 1

[0053] A human-computer interaction device for an LKJ simulation training platform, comprising:

[0054] The housing 100 has a display device 200 and control buttons 300 on one side. The display device 200 and control buttons 300 are arranged sequentially from top to bottom on the outer wall of the housing 100. The control buttons 300 include a plurality of vertically arranged button bodies 301 on the housing 100 and equidistantly along the length of the display device 200. It also includes other electrical components, such as a power module, which will not be detailed here.

[0055] Disinfection device 400, mounted on housing 100, is used to disinfect the surfaces of display device 200 and control buttons 300.

[0056] Please see the appendix Figure 2 -Appendix Figure 6

[0057] The disinfection device 400 includes:

[0058] Mounting base 401 is embedded in the outer wall of housing 100, from the attached Figure 1 As can be seen, the mounting base 401 is positioned above the display device 200; a guide post 403 is horizontally fixed inside the mounting base 401, preferably rectangular, and a slider 404 is slidably mounted on the outer wall of the guide post 403. The slider 404 and one inner wall of the mounting base 401 are connected by a tension spring 421, which is used to drive the slider 404 to reset; a rotating shaft 405 is inserted on the slider 404, and a bearing is provided at the connection between the rotating shaft 405 and the slider 404. The outer end of the rotating shaft 405 is connected to a cleaning component for disinfecting the surfaces of the display device 200 and the control buttons 300. The cleaning component has horizontal and vertical states. A pull cord flipping component connected to the cleaning component is provided on the slider 404. One end of the pull cord flipping component extends along the axis of the guide post 403 to the other end of the guide post 403 and is connected to a driving component. The driving component is used to cause the pull cord flipping component to drive the cleaning component to rotate from the horizontal state to the vertical state and then drive the slider 404 to move from one end of the guide post 403 to the other end. For example, with an attached... Figure 3 As shown, initially, slider 404 is located at the left end of guide post 403. At this time, the cleaning component is in a horizontal state and will not interfere with the use of display device 200 and control button 300. The driving component is located at the right end of guide post 403. It should also be noted that the moving distance of slider 404 is greater than the length of display device 200 and control button 300.

[0059] The driving component includes a toothed gear 409 located on the inner wall of the mounting base 401 and driven to rotate by a rotating device. A driven gear 410 meshes with one side of the toothed gear 409. A pull rope flipping component is wound around the outer wall of the shaft of the driven gear 410. The rotating device is, for example, a motor and a reducer. The toothed gear 409 rotates to drive the driven gear 410, which causes its shaft to wind up the pull rope 408. In turn, the pull rope 408 pulls the slider 404 to move. When the slider 404 moves from the left end of the guide post 403 to the right end of the guide post 403, the toothless section on the toothed gear 409 corresponds to the driven gear 410. At this time, under the action of the tension spring 421, the slider 404 resets and moves. During its reset movement, the cleaning component returns from a vertical state to a horizontal state, completing the automatic storage.

[0060] Preferably, the cleaning component in this embodiment includes:

[0061] A hollow base 411 is fixedly sleeved at one end onto the outer wall of the rotating shaft 405. The hollow base 411 contains a storage chamber 413 for storing disinfectant. The hollow base 411 also has an opening for adding disinfectant to the storage chamber 413. When no disinfectant is added, the opening is sealed with a cover 402. One side of the hollow base 411 has a corrosion-resistant sponge strip 412 for contact with the display device 200 and control buttons 300. The corrosion-resistant sponge strip 412 is, for example, made of polyurethane sponge. The outer wall of the hollow base 411 has equidistant openings... There are several sets of seepage holes 414 for wetting the corrosion-resistant sponge strip 412. The disinfectant liquid in the storage chamber 413 seeps out from the seepage holes 414 to wet the corrosion-resistant sponge strip 412. The corrosion-resistant sponge strip 412 rubs against the surface of the display device 200 and the control button 300 to disinfect them. Furthermore, in actual practice, a strip of ultraviolet germicidal lamp can be horizontally installed on the inner wall of the mounting base 401 at the position corresponding to the corrosion-resistant sponge strip 412. This will not be described in detail here.

[0062] Preferably, the pull cord flipping component of this embodiment includes:

[0063] A protrusion 406 is horizontally fixed to the inner wall of the rotating shaft 405 and located within the cavity of the slider 404. A limiting block 407 is provided within the cavity of the slider 404 at a position below the rotating shaft 405; and...

[0064] The pull rope 408 is connected to the protrusion 406 at one end and passes through the limiting block 407 and the slider 404 at the other end before being wound around the outer wall of the shaft of the driven gear 410. The slider 404 and the inner wall of the mounting base 401 near the driving member are both provided with guides for guiding the pull rope 408. The guides are, for example, guide wheel sets.

[0065] When the pull rope 408 drives the protrusion 406 to engage with the limiting block 407, the rotating shaft 405 drives the cleaning component to rotate from a horizontal state to a vertical state. When the driving component is working, the pull rope 408 is wound up first, and the pull rope 408 pulls the protrusion 406 to make the rotating shaft 405 rotate. When the cleaning component rotates to a vertical state, the protrusion 406 engages with the limiting block 407. At this time, the pull rope 408 continues to be wound up, which will cause the slider 404 to move.

[0066] Preferably, in order to prevent the slider 404 from moving due to force when the pull rope 408 pulls the protrusion 406 and causes the rotating shaft 405 to rotate, the disinfection device 400 of this application further includes a locking member, which includes:

[0067] A drive gear 415 is sleeved on the outer wall of the rotating shaft 405. A transverse rack 416 meshes on the drive gear 415. The transverse rack 416 is slidably disposed on the front side of the slider 404. A wedge block 417 is provided on the transverse rack 416.

[0068] The elastic telescopic rod 418 has one end fixed to the top inner wall of the mounting base 401, and the other end inserted into a socket in the top of the slider 404. The axis of the socket is perpendicular to the axis of the rotation shaft 405. A ball bearing is embedded in the movable end of the elastic telescopic rod 418, and a connecting arm 419 is provided on the outer wall of the movable end of the elastic telescopic rod 418. The connecting arm 419 extends to the outside of the slider 404 through a through-hole. The connecting arm 419 is, for example, L-shaped, and the bottom end of the connecting arm 419 is provided with a wedge block 417. The roller with the inclined side has the inclined side of the wedge block 417 facing the driving component, i.e. the right side. When the pull rope 408 pulls the protrusion 406 to make the rotating shaft 405 rotate, the driving gear 415 drives the transverse rack 416 to move the wedge block 417 to the right. The movement of the wedge block 417 drives the connecting arm 419 to move the movable end of the elastic telescopic rod 418 upward out of the insertion hole. When it is out of the insertion hole, the protrusion 406 is in contact with the limiting block 407. At this time, the slider 404 can be moved along the guide post 403 under force.

[0069] Wedge block 2 420 is disposed on the inner wall of slider 404 on the side away from the driving member, and the inclined side of wedge block 2 420 is opposite to the inclined side of wedge block 1 417;

[0070] When the rotating shaft 405 drives the cleaning component to rotate to a vertical position, the drive gear 415 drives the transverse rack 416, causing the wedge block 417 to push the connecting arm 419 and disengage the movable end of the elastic telescopic rod 418 from the insertion hole. The wedge block 420 is used to drive the elastic telescopic rod 418 back into the insertion hole. Specifically, when the slider 404 is reset with the tension spring 421, the wedge block 420 will first contact the movable end of the elastic telescopic rod 418. Then, the wedge block 420 drives the movable end of the elastic telescopic rod 418 upward to the slider 404 and moves on the top surface of the slider 404 (the top surface of the wedge block 417 is parallel to it). When the elastic telescopic rod 418 corresponds to the insertion hole, the elastic telescopic rod 418 elastically resets and re-engages in the insertion hole.

[0071] Preferably, the cleaning component in this embodiment further includes:

[0072] The movable sealing plate 423, for example, L-shaped, is located on one side of the inner wall of the liquid storage cavity 413, as shown in the attached image. Figure 6 As shown, the top of the movable sealing plate 423 fits against the inner wall of the top of the liquid storage cavity 413 to seal the second leakage hole; the movable sealing plate 423 is provided with several sets of second leakage holes that cooperate with the first leakage hole 414; one end of the movable sealing plate 423 penetrates through the side wall of the liquid storage cavity 413 and extends into the groove 422 opened on the hollow seat 411; one end of the movable sealing plate 423 located in the liquid storage cavity 413 is connected to the inner wall of the liquid storage cavity 413 by a spring 425; the other end of the movable sealing plate 423 is provided with a rod corresponding to the rotating shaft 405; and,

[0073] The eccentric disk 424 is eccentrically and movably sleeved on the outer wall of the rotating shaft 405 and connected to the slider 404 through a bracket. It is not affected by the rotation of the rotating shaft 405. The eccentric disk 424 slides against the rod.

[0074] When the hollow seat 411 is in a horizontal state, the first leakage hole 414 and the second leakage hole are misaligned, so that the disinfectant in the storage cavity 413 cannot wet the corrosion-resistant sponge strip 412. When the hollow seat 411 is in a vertical state, the movable sealing plate 423 is moved by the rod through the eccentric disk 424, causing the first leakage hole 414 and the second leakage hole to correspond, so that the disinfectant in the storage cavity 413 wets the corrosion-resistant sponge strip 412.

[0075] Please see the appendix Figure 7 - Appendix Figure 9

[0076] In order to prevent the control button 300 from being pressed when the cleaning component rubs against the display device 200 and the control button 300, this application also includes a button locking device 500 disposed in the housing 100 to limit the button body 301 from being pressed by the cleaning component.

[0077] The keypad locking device 500 includes:

[0078] Mounting plate 501 is located inside housing 100. Mounting plate 501 is provided with a linkage driven by cleaning component. The linkage is connected to several sets of locking components 2. The several sets of locking components 2 correspond one-to-one with several sets of button bodies 301. For example, there are five sets of locking components 2.

[0079] The second locking component is used to lock the button body 301 when the cleaning component rotates to a vertical position and moves from one end of the guide post 403 to the other end, so that the button body 301 cannot be pressed down.

[0080] Preferably, the linkage in this embodiment includes:

[0081] The movable plate 507 is parallel to and slidably disposed on the mounting plate 501, and moves along the width direction of the mounting plate 501. Both ends of the movable plate 507 are provided with toothed segments 508.

[0082] A drive gear 503 is rotatably mounted on one end of a mounting plate 501 via a rotating shaft and meshes with a tooth segment 508. One end of the rotating shaft movably passes through one side of the housing 100 and is fixedly fitted with a toggle arm 502. The toggle arm 502 is initially in a vertical state. In practice, by setting a limiting structure on the outer wall of the housing 100, it can rotate within a certain angle, that is, it can only rotate to a vertical state or an inward tilting state. When the cleaning component rotates to the vertical state, it will first contact the toggle arm 502 through the corrosion-resistant sponge strip 412. Since the corrosion-resistant sponge strip 412 is flexible and cooperates with the limiting structure, the corrosion-resistant sponge strip 412 will deform and pass through the toggle arm 502 to the left side of the toggle arm 502. When the corrosion-resistant sponge strip 412 moves to the right, it will drive the toggle arm 502 to tilt inward from the vertical state.

[0083] The other end of the mounting plate 501 is movably inserted through one side of the housing 100 via a second pivot and is fixedly fitted with a second actuating arm 506. Both the first actuating arm 502 and the second actuating arm 506 are actuated by a vertically positioned cleaning component. The first actuating arm 502 and the second actuating arm 506 are located at the two ends of the length direction of the display device 200 and the control button 300, respectively. At the same time, the first actuating arm 502 and the second actuating arm 506 are on the movement path of the cleaning component to cooperate with the cleaning component. Similarly, a structure for limiting its rotation can be provided on the outer wall of the housing 100. After the cleaning component actuates the first actuating arm 502, it moves vertically toward the second actuating arm 506. Actuating the second actuating arm 506 releases the lock on the button body 301 so that the cleaning component can be rotated and reset to a horizontal state.

[0084] Rotating shaft 2 is meshed with rotating shaft 3 via gear set 505 on the side facing rotating shaft 1. Gear set 505 consists of two sets of meshing gears. The outer wall of rotating shaft 3 is fitted with driving gear 2 504 that cooperates with tooth segment 508 at the other end of moving plate 507. When the actuating arm 2 506 is moved from the vertical state to the tilted state, driving gear 2 504 and the other tooth segment 508 cooperate to drive moving plate 507 to reset and actuating arm 1 502 to return to the vertical state.

[0085] A wedge-shaped block 3 510 is provided on the movable plate 507 at the position corresponding to the locking component 2, with the inclined edge of the wedge-shaped block 3 510 facing to the left.

[0086] When the first toggle arm 502 tilts inward by moving the vertical cleaning component, the second toggle arm 506 rotates from tilted to vertical, and at the same time, the third wedge block 510 drives the second locking component to lock the button body 301; when the second toggle arm 506 in the vertical state is reset to the tilted state by moving the vertical cleaning component, the third wedge block 510 drives the second locking component to unlock the button body 301.

[0087] Preferably, the second locking element in this embodiment includes:

[0088] A limiting plate 509 is slidably disposed within a groove opened on the mounting plate 501. The groove extends along the width direction of the mounting plate 501. An elastic element 513 is provided between the limiting plate 509 and the inner wall of the groove to ensure that the limiting plate 509 is always in contact with the inclined surface of the wedge block 3 510. The limiting plate 509 slides against the inclined surface of the corresponding wedge block 3 510 using a contact rod 511. A clearance opening 512 is provided on the limiting plate 509 at the position corresponding to the button body 301 for the button body 301 to pass through. For example, see attached... Figure 9 As shown, the existing button body 301 typically includes a button a, a reset spring b that resets the button a, and a contact c that cooperates with the button a and is located on the circuit board d.
