Description

Technical Field

[0001] This application relates to emergency evacuation devices for rail vehicles, and more specifically to a full-width electric emergency safety device for low-floor modern trams. Background Technology

[0002] Existing emergency evacuation devices are limited by the dimensions of subway tunnels, preventing them from being built too wide. Most can only allow one person to pass at a time, rendering them ineffective in emergency evacuation due to the chaotic and disorganized state of the passengers. Furthermore, passengers with mobility issues, such as those in wheelchairs, cannot evacuate through these devices. If a train stops abruptly between platforms, the sides of the train cannot be used for evacuation, making it difficult for wheelchair users to evacuate using existing emergency evacuation devices.

[0003] Therefore, there is a need for a full-width electric emergency safety device for low-floor modern trams that can evacuate passengers with mobility impairments who use wheelchairs, prevents wheelchairs from shifting during movement, and is applicable to low-floor vehicles.

[0042] Indicative low-floor modern tram full-width electric emergency safety device

[0043] refer to Figures 1 to 14 According to a preferred embodiment of the present invention, a full-width electric emergency safety device for low-floor modern trams includes a fully openable door 10, a sealed door frame 20, and an electric door opening mechanism 30. The fully openable door 10 is rotatably mounted on the sealed door frame 20, and the electric door opening mechanism 30 faces the fully openable door 10, pushing the fully openable door 10 to a predetermined angle by pressing it. It should be understood by those skilled in the art that a pneumatic spring is also provided on each side of the sealed door frame 20. That is, when the fully openable door 10 is opened to the predetermined angle by the electric door opening mechanism 30, the two pneumatic springs start to operate, thereby pushing the fully openable door 10 to the preset angle. It is worth mentioning that the electric door opening mechanism 30 is configured to open the fully openable door 10 pneumatically or manually. It should be noted that the full-width pneumatic emergency safety device for the Type A subway car also includes a deployable ramp 40 and a ramp retraction mechanism 50. The deployable ramp 40 is retractable into the ramp retraction mechanism 50. Furthermore, the deployable ramp 40 can be extended to a predetermined length and contact the external tracks of the subway, facilitating rapid passenger evacuation. The fully opening doors not only ensure the integrity of the windshield, guaranteeing the transparency and visibility of the driver's cab, but also enhance the aesthetics, improve lighting for the evacuation route, and facilitate the collection of external information, thereby increasing evacuation safety and enabling rapid passenger evacuation in emergencies. Those skilled in the art should understand that the deployable ramp 40 deploys at an angle, so that the end of the deployable ramp 40 opposite to the ramp retraction mechanism 50 contacts the ground tracks.

[0044] It should be noted that existing emergency evacuation devices are limited by the dimensions of subway tunnels, preventing them from being built too wide. Most can only allow one person to pass at a time, rendering them ineffective in an emergency evacuation due to the chaotic and disorganized state of the passengers. Furthermore, passengers with mobility issues, such as those in wheelchairs, cannot evacuate through these devices. If a train stops abruptly between platforms, the sides of the train cannot be used for evacuation, making it difficult for wheelchair users to evacuate using the existing emergency evacuation devices.

[0045] Among them, such as Figure 1 The low-floor modern tram full-width electric emergency safety device shown also includes a liftable cover plate, which is mounted on the ramp retraction mechanism 50. That is, when the deployable ramp 40 is needed, the user can manually disassemble it by lifting the cover plate, and then the deployable ramp 40 unfolds, with its end placed on the ground. It should be noted that a control console 60 is also provided on one side of the cover plate. The control console 60 is designed to move forward and backward a predetermined distance, thereby reserving space for the subsequent evacuation of wheelchair passengers. Specifically, when the deployable ramp 40 unfolds, the space on the side of the control console 60 near the cover plate is no longer blocked by the cover plate. Then, the control console 60 moves a predetermined distance away from the fully opening door 10, at which point wheelchair passengers can move to the side of the control console 60 near the fully opening door 10.

[0046] It should be noted that the low-floor modern tram full-width electric emergency safety device also includes a movable ramp assembly 70, which is located on the side of the control console 60 near the fully open door 10.

[0047] It should be noted that the movable ramp assembly 70 includes a first plate 71, which has a base plate 711 and a side plate 712. One end of the base plate 711 is connected to one end of the side plate 712, and the base plate 711 is perpendicular to the side plate 712. Furthermore, one end of the first plate 71 is close to the control console 60, and the other end is close to the fully opening door 10.

[0048] Additionally, it should be noted that each side of the side panel 712 has a handrail 200, which are arranged opposite to each other and spaced apart by a predetermined distance. Specifically, when the fully open door 10 is locked, the unfolding ramp 40 unfolds, and the control panel 60 moves a predetermined distance away from the fully open door 10, thereby reserving a predetermined space to facilitate a wheelchair passenger to access the movable ramp assembly 70.

[0049] It is worth mentioning that the length of the base plate is greater than the length of the side plate 712, and the first plate 71 also has a rotating plate 713. One end of the rotating plate 713 is rotatably connected to one end of the base plate 711, and the other end is flush with one end of the side plate 712. Specifically, the sum of the lengths of the rotating plate 713 and the side plate 712 is the same as the length of the base plate. The rotating plate 713 is also configured to rotate downwards at a predetermined angle. In addition, it should be noted that when the fully open door 10 is opened, the first plate 71 moves a predetermined distance away from the control panel 60 until the rotating plate 713 passes through the sealing door frame 20. At this time, the rotating plate 713 swings downwards at a predetermined angle so that the end of the rotating plate 713 away from the base plate 711 contacts the ground, and a wheelchair passenger can evacuate from the rotating plate 713.

[0050] It is worth mentioning that there are also two opposing first guide blocks 100 between the console 60 and the fully openable door 10, with one end of the two first guide blocks 100 close to the console 60 and the other end close to the fully openable door 10.

[0051] The first plate 71 has a groove 7101 on its base plate 71. Both first guide blocks 100 are placed in the groove 7101, and the opposite sides of the two first guide blocks 100 are in contact with the side walls forming the groove 7101. The movable ramp assembly 70 also includes a first drive assembly 300, which is positioned between the two first guide blocks 100. The first drive assembly 300 also has a movable connecting block, which is fixedly connected to the bottom wall forming the groove 7101. Thus, when the connecting block moves closer to the fully open door leaf 10, the first plate 71 moves synchronously a predetermined distance. The first drive assembly 300 can be implemented as a linear motor, i.e., a screw-slider transmission method, to drive the first plate 71 to move back and forth. Furthermore, when the rotating plate 713 passes through the fully open door leaf 10, the first drive assembly 300 stops operating.

[0052] Additionally, it should be noted that the side plate 712, on the side opposite to the base plate 711, has a first mounting groove, and the bottom wall forming the first mounting groove has a first insertion hole. The rotating plate 713, on the side near the side plate 712, has a second insertion hole, which is directly opposite the first insertion hole. It is worth mentioning that a second drive assembly 400 is also provided in the first mounting groove. The second drive assembly 400 also has a telescopic rod, which is placed in the first insertion hole. The second drive assembly 400 is configured to drive the telescopic rod to extend a predetermined length. The telescopic rod can pass through the first insertion hole and be placed in the second insertion hole, thereby defining the position of the rotating plate 713. When the first drive assembly 300 stops operating, the second drive assembly 400 starts operating, driving the telescopic rod to retract a predetermined length, so that the rotating plate 713 is no longer limited by the telescopic rod. Then, due to inertia, the rotating plate 713 swings downward a predetermined distance until the end of the rotating plate 713 contacts the ground.

[0053] It should also be noted that the rotating plate 713 is also provided with a guide component 72 that can be raised and lowered to a predetermined height. The guide component 72 is positioned between two external wheelchairs to limit the direction of movement of the wheelchairs and prevent the external wheelchairs from deviating when passing the rotating plate 713.

[0054] Furthermore, the rotating plate 713 has a second mounting groove 71301, two first mounting holes 71302 and two second mounting holes (not shown in the figure) on the side facing away from the ground. The guide component 72 is disposed in the second mounting groove 71301. The two first mounting holes 71302 are arranged opposite to each other and are located on both sides of the second mounting groove 71301. The two second mounting holes are also arranged opposite to each other and are located on both sides of the second mounting groove 71301.

[0055] It should be noted that the guide assembly 72 includes a guide plate 721, which is vertically and flexibly positioned within the second mounting groove 71301. The guide plate 721 has two opposing first protrusions 7211 on the side near the second mounting groove 71301, and the bottom wall forming the second mounting groove 71301 has two opposing second protrusions 500. The two first protrusions 7211 correspond one-to-one with the two second protrusions 500. It is worth mentioning that each first protrusion 7211 has a cross-section to reserve predetermined space for the operation of other components of the guide assembly 72. It should be noted that each of the first protrusions 7211 has an insertion rod 7212 on the side near the corresponding second protrusion 500, and each of the second protrusions 500 has a first connecting hole on the side near the corresponding first protrusion 7211. The two insertion rods 7212 correspond one-to-one with the two first connecting holes, and the end of the insertion rod 7212 facing away from the first protrusion 7211 is placed in the corresponding first connecting hole.

[0056] It is worth mentioning that each of the insertion rods 7212 is also provided with a first elastic element 722, the two ends of which respectively contact the sides of the first protrusion 7211 and the second protrusion 500 that are close to each other. Specifically, when the guide plate 721 loses its support, the first elastic element 722 can play the role of supporting the guide plate 721.

[0057] It is worth mentioning that the guide assembly 72 also includes two first pressing members 723. One end of each of the two first pressing members 723 is placed inside the two first mounting holes 71302, and the other end is placed outside. Each of the first pressing members 723 also has a first pressing surface at the end near the first mounting hole 71302.

[0058] Furthermore, the guide assembly 72 also includes two second pressing members 724, one end of each of the two second pressing members 724 being placed in the two second mounting holes, and the other end of each being placed on the outside, and each of the second pressing members 724 having a second pressing surface at the end near the second mounting hole.

[0059] Furthermore, each of the two side walls forming the second mounting groove 71301 has a second connecting hole 71303 and a third connecting hole, and the two second connecting holes 71303 correspond one-to-one with the two first mounting holes 71302, and the two third connecting holes also correspond one-to-one with the second mounting holes. Each second connecting hole 71303 is also connected to the corresponding first mounting hole 71302, and each third connecting hole is also connected to the corresponding second mounting hole. In addition, each second connecting hole 71303 is also connected to the adjacent third connecting hole.

[0060] It is worth mentioning that the guide assembly 72 also includes two first connectors 725, each corresponding to one of the two second connecting holes 71303. One end of each first connector 725 is placed in the corresponding first mounting hole 71302 and contacts the end of the first pressing member 723, while the other end is placed between the corresponding first protrusion 7211 and the second protrusion 500. It should be noted that the first pressing member 723 can move downwards a predetermined distance under force, while the first connector 725 rotates a predetermined angle due to the force. At this time, the end placed between the first protrusion 7211 and the second protrusion 500 is configured to contact the corresponding first protrusion 7211, thereby defining the position of the guide plate 721. Specifically, each first connector 725 has a first pressing portion 7251 and a second pressing portion 7252, located at both ends of the first connector 725. Figure 10 , Figure 13 As shown, the first pressure-receiving part 7251 contacts the corresponding pressing surface. Therefore, when the first pressing member 723 moves downward a predetermined distance, the first pressure-receiving part 7251, under pressure, causes the first connecting member 725 to rotate until the first pressing member 723 is no longer subjected to external force. At this point, the first connecting member 725 stops rotating. It should also be noted that the second pressure-receiving part 7252 is located between the first protrusion 7211 and the second protrusion. When the first pressure-receiving part 7251 causes the first connecting member 725 to rotate, the second pressure-receiving part 7252 rotates synchronously. At this time, the top of the second pressure-receiving part 7252 contacts the side of the first protrusion 7211 closest to the second protrusion 500, thereby enabling the first connecting member 725 to support the guide plate 721.

[0061] Additionally, it should be noted that each of the first protrusions 7211 has a third mounting groove on the side near the second protrusion 500. Each of the third mounting grooves also has a first telescopic component 600. The first telescopic component 600 includes a second elastic element 700 and a first movable element. One end of the second elastic element 700 is fixedly connected to the bottom wall forming the third mounting groove, and the other end is fixedly connected to the first movable element. The end of the first movable element facing away from the second elastic element 700 is placed externally. Furthermore, the end of the first movable element facing away from the second elastic element 700 also has an annular pressure end. Each of the second pressure portions 7252 also has a limiting groove. When the second pressure portion 7252 moves towards the first telescopic component, it presses the annular pressure end, causing the first movable element to retract a predetermined distance until the end of the first movable element is positioned within the limiting groove. That is, the end of the first movable element will strike the limiting groove and produce a sound, thereby reminding the user that the first connecting member 725 has rotated into place. At this point, the guide block has been supported.

[0062] It is worth mentioning that the guide assembly 72 also includes two second connectors 726, each of which corresponds to one of the two third connecting holes. The two second connectors 726 are respectively placed in the two third connecting holes, and one end of each of the two second connectors 726 is respectively placed in the second mounting hole. Each end of the second connector 726 placed in the second mounting hole also has a third pressure-bearing part 7261, which is in contact with the second extrusion surface. It should also be noted that each of the second connecting members 726 is also engaged with the adjacent first connecting member 725. That is, when the first connecting member 725 rotates, the second connecting member 726 rotates synchronously, as shown in 9 to 12. When the first pressure-bearing part 7251 contacts the first pressing surface, the third pressure-bearing part 7261 disengages from the second pressing surface. When the first pressing member 723 presses down, the first linkage rotates counterclockwise by a predetermined angle, and at the same time, the second connecting member 726 rotates counterclockwise by a predetermined angle until the third pressure-bearing part 7261 approaches the second pressing surface. At this time, the second pressure-bearing part... The top of part 7252 contacts the corresponding first protrusion 7211. In addition, when the guide plate 721 needs to be stored, the user needs to press the second pressing member. At this time, the third pressing part 7261 drives the second connecting member 726 to rotate counterclockwise a predetermined distance, and the first connecting member 725 resets. At this time, the second pressing part 7252 is no longer located between the first protrusion 7211 and the second protrusion 500. Since the cross section of the first protrusion 7211 has reserved space, when the guide plate 721 is pressed down, the first protrusion 7211 and the second pressing part 7252 will not have an interference problem.

[0063] It should also be noted that a second elastic element 700 is provided at the bottom of both the first mounting hole 71302 and the second mounting hole. Multiple second elastic elements 700 are in contact with the ends of the corresponding first pressing element 723 and second pressing element 724, thereby ensuring that the first pressing element 723 or the second pressing element can be reset after being pressed.

[0064] It should also be noted that each of the insertion rods 7212 has two oppositely arranged slots, and each wall surface forming the first connecting hole has two oppositely arranged fourth mounting slots, with each of the four fourth mounting slots corresponding to one of the two slots. A second telescopic component 800 is also provided in each of the four fourth mounting slots, with one end of the second telescopic component 800 placed in the fourth mounting slot and the other end placed in the corresponding slot.
