Description

Technical Field

[0001] This utility model relates to the field of train auxiliary devices, and in particular to an auxiliary device for indicating the opening direction of train doors. Background Technology

[0002] High-speed trains have doors on both sides. When the train stops at a station, the driver should open the door on the platform side to allow passengers to board and alight. Due to the short stop times and the numerous required procedures for the driver, coupled with the abundance of buttons and signals in the driver's cab, drivers are prone to accidentally opening doors. If a driver mistakenly opens a door on the side that shouldn't be open, the unsupported side could pose a serious safety hazard, causing passengers to fall onto the tracks. Therefore, to ensure the safety of high-speed train operations, there is a real need for a system that can instruct drivers on the correct door opening method; however, there is currently no practical, simple, and easily implemented technical solution in this regard. Utility Model Content

[0003] The purpose of this utility model is to address the problems existing in the background technology by proposing an auxiliary device that indicates the opening direction of train doors. It has a simple structure, is easy to promote, and can instruct train drivers to open the correct side door, thus preventing safety accidents caused by opening the wrong door.

[0004] The present invention provides an auxiliary device for indicating the opening direction of train doors. Two sets of auxiliary devices are used in conjunction. Each auxiliary device includes a placement frame, an alarm component, a triggering component, a limiting component, and a central controller. The placement frame has multiple legs at its bottom and an inner accommodating space.

[0022] Example 1

[0023] like Figures 1-7 As shown in the figure, this embodiment proposes an auxiliary device for indicating the opening direction of train doors. Two sets of auxiliary devices are used in combination. One set of auxiliary devices is placed on the control panel for controlling the opening and closing of the left door of the train, and the other set of auxiliary devices is placed on the control panel for controlling the opening and closing of the right door of the train. The two control panels are located on the left and right sides of the train driver, respectively.

[0024] The auxiliary device includes a placement rack, an alarm component, a triggering component, a limit component, and a central controller.

[0025] The bottom of the shelf has multiple legs and an inner accommodating space. After the shelf is placed on the control panel, the button 28 on the control panel and the cap 27 for covering the button 28 are both located inside the accommodating space. The cap 27 is rotatably mounted on the control panel and can be flipped over to cover the outer periphery of the button 28 or removed from the outer periphery of the button 28.

[0026] like Figures 1-3 As shown, the alarm assembly includes a bracket 4 mounted on a shelf, a voice alarm 17, a first conductive connector 5 mounted on the bracket 4, and wires electrically connected at both ends to the first conductive connector 5 and the voice alarm 17, respectively. The voice alarm 17 emits a warning sound during operation to remind the train driver that the wrong auxiliary device has been taken; if the correct device has been taken, the voice alarm 17 will not sound.

[0027] The triggering assembly includes a fixed plate 6 mounted on a placement frame, an abutment rod 7 vertically slidably mounted on the fixed plate 6, a lifting plate 10 mounted on the abutment rod 7, a first spring 8 connected at both ends to the fixed plate 6 and the lifting plate 10 respectively, a slide rod 9 vertically mounted on the lifting plate 10 and slidably connected to the fixed plate 6, a second conductive connector 11 located at the bottom of the lifting plate 10, and a battery electrically connected to the second conductive connector 11. The battery powers the entire auxiliary device. The second conductive connector 11 is located above the first conductive connector 5. The abutment rod 7 can slide vertically on the fixed plate 6, and when the auxiliary device is placed on the control panel, the bottom end of the abutment rod 7 abuts against the control panel.

[0028] The limiting assembly includes a locking bar and a drive assembly for moving the locking bar under or away from the lifting plate 10. The two sets of auxiliary devices are used in conjunction; when the train is in motion, the locking bars in both sets of auxiliary devices are positioned below the lifting plate 10.

[0029] When the train stops near the left platform, the locking bar in the left auxiliary device remains below the lifting plate 10, and the drive component in the right auxiliary device drives the locking bar to move away from below the lifting plate 10, releasing the restriction on the lifting plate 10. At this time, if the train driver picks up the left auxiliary device, the locking bar will block the lifting plate 10, and the second conductive connector 11 will not contact the first conductive connector 5, so no alarm will sound. The train driver can further open the cover 27 and press the button 28 to open the left door of the train. If the train driver mistakenly picks up the right auxiliary device, the compressed first spring 8 will push the lifting plate 10 downward, and the lifting plate 10 will drive the second conductive connector 11 to move downward. The second conductive connector 11 will contact the first conductive connector 5 and conduct electricity, that is, the battery can power the voice alarm 17 through the second conductive connector 11, the first conductive connector 5 and the wire. The voice alarm 17 will sound an alarm to remind the driver that the wrong auxiliary device has been picked up. The driver will not mistakenly press the button 28 on the right control panel and will not mistakenly open the right door of the train. Instead, the driver will pick up the left auxiliary device and press the button 28 on the left control panel to open the left door.

[0030] Similarly, when the train stops near the right platform, the locking bar in the right auxiliary device remains below the lifting platform 10, and the drive component in the left auxiliary device drives the locking bar to move away from below the lifting platform 10, releasing the restriction on the lifting platform 10. At this time, if the train driver picks up the right auxiliary device, the auxiliary device will not alarm, and the driver can further open the right door of the train by pressing button 28. If the driver picks up the wrong left auxiliary device, the auxiliary device will alarm, the driver will not continue to press button 28 on the left control panel, will not open the left door, but will instead pick up the right auxiliary device and press button 28 on the right control panel to open the right door of the train.

[0031] The central controller is connected to the drive assembly and the voice alarm 17 respectively. A signal transmitter is installed on the mounting frame to transmit data between the train and the central controller. The central controller can control the operation of the drive assembly to move the lifting platform 10 under the lifting platform 10 or move it away from under the lifting platform 10.

[0032] This embodiment has a simple structure, is easy to promote, and can instruct train drivers to open the correct side door, preventing safety accidents caused by opening the wrong door. When the train arrives at a station, the data on whether the train stops at the left or right platform is known. The central controller receives this data through a signal transmitter and controls the drive component in the auxiliary device on the side where the door does not need to be opened to move the drive bar away from under the lifting platform 10. If the train driver takes the wrong auxiliary device, the voice alarm 17 is powered on, and the central controller can control the powered voice alarm 17 to sound. If the train driver takes the correct auxiliary device, the voice alarm is not powered on, the central controller will not control the de-powered voice alarm 17 to sound, and the driver opens the correct side door.

[0033] Example 2

[0034] like Figures 1-7 As shown, this embodiment proposes an auxiliary device for indicating the opening direction of train doors. Compared to Embodiment 1, in this embodiment, the placement frame includes a placement seat 1, a mounting plate 18, and a mounting cover 2 arranged sequentially from bottom to top. The bottom of the placement seat 1 has a stud portion that penetrates the mounting plate 18 and the mounting cover 2, and a nut 20 is threadedly connected to the lower part of the stud portion. The placement seat 1, mounting plate 18, and mounting cover 2 are aligned and fitted together from bottom to top, so that the stud portion of the placement seat 1 penetrates the mounting plate 18 and the mounting cover 2. Then, the nut 20 is screwed on to tighten the three parts, thus obtaining the entire placement frame. The support legs are located at the lower part of the placement seat 1, and multiple support legs can support the control panel, surrounding the outer periphery of the button 28.

[0035] like Figure 1 and Figure 2 As shown, LED lights 19 are installed on the mounting plate 18, and the mounting cover 2 is a light-transmitting plastic structure. When the train arrives at the station, the central controller controls the LED lights 19 on the auxiliary device on the side where the door needs to be opened to emit green light, and controls the LED lights 19 on the auxiliary device on the side where the door does not need to be opened to emit red light. The light shines through the mounting cover 2 and can be observed by the train driver. The driver is more likely to pick up the auxiliary device emitting green light and will not mistakenly pick up the auxiliary device emitting red light. If the driver mistakenly picks up the auxiliary device emitting red light, the voice alarm 17 will still be triggered.

[0036] To further enhance the accuracy of door opening instructions for train drivers, a light shield 3 is installed on the top of the mounting cover 2. Two of the two auxiliary devices have "Left" and "Right" markings on their respective light shields 3, indicating the door opening direction. The light shield 3 with "Left" is part of the left-side auxiliary device, and the light shield 3 with "Right" is part of the right-side auxiliary device, placed on the two control panels on opposite sides. The light shields 3 are opaque to prevent the LED lights 19 from interfering with the clear display of "Left" and "Right".

[0037] like Figure 2 and Figure 3 As shown, the rack is a horizontally distributed rack 14. The drive assembly includes a motor 12 mounted on the mounting cover 2, a gear 13 connected to the output end of the motor 12 and meshing with the rack 14, a slide 15 mounted on the end of the rack 14, and a guide rod 16 mounted on the mounting cover 2 for the slide 15 to slide. The output end of the motor 12 can rotate in both directions. The motor 12 drives the gear 13 to rotate, the gear 13 drives the rack 14 to move, the rack 14 drives the slide 15 to move, and the guide rod 16 guides the slide 15 to move horizontally, thereby moving the rack 14 horizontally, moving it under the lifting plate 10, or moving it away from under the lifting plate 10. When it is necessary to move the rack 14 under the lifting plate 10, the auxiliary device must be placed on the control panel in advance, the abutment rod 7 abuts against the control panel, the lifting plate 10 compresses the first spring 8, and the lifting plate 10 rises to a position higher than the rack 14, and then the rack 14 can be moved horizontally under the lifting plate 10.

[0038] In this embodiment, the green light emitted by the LED light 19 can remind the train driver to pick up the correct auxiliary device, and then the train door on the side that needs to be opened can be controlled to open via the control panel.

[0039] Example 3

[0040] like Figures 1-7 As shown, this embodiment proposes an auxiliary device for indicating the opening direction of train doors. Compared to Embodiment 1, this embodiment further includes two sets of clamping assemblies symmetrically distributed about the placement frame. Each clamping assembly includes a clamping plate 24, a connecting rod 25 connected to the clamping plate 24, a guide cylinder 26 for horizontal sliding of the connecting rod 25, and a second spring located inside the guide cylinder 26. The guide cylinder 26 is mounted on the support leg of the placement frame, and the two ends of the second spring are connected to the connecting rod 25 and the support leg, respectively. When the auxiliary device is placed on the control panel, the cap 27 covers the outer periphery of the button 28, and the two clamping plates 24 can clamp onto the cap 27 from both sides, compressing the second spring. This improves the stability of the entire auxiliary device during train operation.

[0041] like Figure 2As shown, the clamping plate 24 is an arc-shaped plate structure, including a vertical plate and an inclined plate at the bottom of the vertical plate. The inclined plate gradually slopes outward from top to bottom. When the auxiliary device is placed on the control panel from top to bottom, the inclined plate guides the placement position. The inclined plate moves along the top edge of the cap 27, and the clamping plate 24 compresses the second spring through the connecting rod 25 until the two clamping plates 24 are respectively clamped on both sides of the cap 27.

[0042] In this embodiment, two sets of clamping components are used to clamp the cap 27 on both sides, thereby improving the stability of the auxiliary device.

[0043] Example 4

[0044] like Figures 1-7 As shown, the auxiliary device for indicating the opening direction of a train door proposed in this embodiment, compared with the first embodiment, further includes multiple sets of counterweight components evenly distributed on the placement frame. The counterweight components include a screw cylinder 22 set on the placement frame, a counterweight block 21 sleeved on the screw cylinder 22, and a bolt 23 threadedly connected to the screw cylinder 22 and pressing the counterweight block 21 onto the placement frame.

[0045] In this embodiment, by adding multiple sets of counterweight components, the stability of the entire auxiliary device can be improved. The screw cylinder 22 is pre-connected to the placement frame, and the counterweight block 21 has a through hole that matches the screw cylinder 22 and can be fitted onto the screw cylinder 22. Then, the bolt 23 is screwed into the screw cylinder 22 to press the counterweight block 21 onto the placement frame. The operation is simple and convenient.

[0046] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
