[0002] Current low-floor modern trams typically feature full-width doors to improve visibility and aesthetics, while also enhancing emergency evacuation accessibility and safety when the doors are open. Additionally, the front of the vehicle is equipped with a door-opening mechanism for activating the full-width doors and a retractable evacuation ramp. The door-opening mechanism opens the full-width doors, and once open, the evacuation ramp extends to facilitate passenger evacuation. The full-width doors, door-opening mechanism, and evacuation ramp together constitute an emergency safety device. However, existing evacuation ramps lack a mechanism to check the sturdiness of their connecting parts after deployment. This necessitates periodic manual inspection of critical connecting parts to prevent detachment, and the stability of the evacuation ramp is crucial for ensuring safe transportation.

[0054] Indicative control method for full-width electric emergency safety devices on low-floor modern trams

[0055] refer to Figures 1 to 5 According to a preferred embodiment of the present invention, a full-width electric emergency safety device for low-floor modern trams is provided. It should be noted that the full-width electric emergency safety device for low-floor modern trams is as follows: Figure 1 As shown, the full-width electric emergency safety device for the low-floor modern tram 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 squeezing it. Those skilled in the art should understand 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 electric emergency safety device for the low-floor modern tram also includes a deployable ramp 40 and a ramp retraction mechanism 50. The deployable ramp 40 is housed in 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, thereby facilitating the rapid evacuation of passengers. 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 track.

[0056] Additionally, it should be noted that the full-width electric emergency safety device for the low-floor modern tram also includes two detection devices 60. The two detection devices 60 are arranged opposite each other, and both detection devices 60 are mounted on the sealing door frame 20 and located below the deployable ramp 40. Specifically, when the deployable ramp 40 first deploys and then swings downwards, one end of the deployable ramp 40 contacts the ground, while the other end of the deployable ramp 40 is rotatably connected to the ramp recovery mechanism 50. It should be noted that the detection device 60 is located between the sealing door frame 20 and the deployable ramp 40, and is configured to detect whether the connection between the deployable ramp 40 and the ramp recovery mechanism 50 is damaged, or whether the connection between the deployable ramp 40 and the ramp recovery mechanism 50 has become detached.

[0057] It should be noted that the wall surface of the sealing door frame 20 connected to the detection device 60 has a first groove 201, and the bottom wall forming the first groove 201 has a second groove 202. The first groove 201 and the second groove 202 are connected, and both the first groove 201 and the second groove 202 are also connected to the outside.

[0058] It is worth mentioning that the detection device 60 includes a first switch assembly 61, which is movably mounted on the sealing door frame and faces the first slide groove 201. The first switch assembly 61 includes a first housing 611, a first swing switch, and a first contact button. The first housing 611 is mounted on the sealing door frame and faces the first slide groove 201. Furthermore, the first swing switch is rotatably mounted on the side of the first housing 611 opposite to the first slide groove 201, and the first contact button is also mounted on the side of the first housing 611 opposite to the first slide groove 201, with a predetermined distance between the first swing switch and the first contact button. Those skilled in the art should understand that the first switch assembly 61 can be implemented as a limit switch, meaning the first swing switch can swing a predetermined angle towards the first contact button to contact it.

[0059] In addition, the detection device 60 also includes a first connecting block 62, the height of the first connecting block 62 is less than the height of the first housing 611, and one side of the first connecting block 62 is fixedly connected to the first housing 611, and the connection between the first connecting block 62 and the first housing 611 can be a screw connection.

[0060] It should be noted that the detection device 60 further includes a second switch assembly 63, which is disposed on the top of the first connecting block 62 and is perpendicular to the first connecting block 62. The first switch assembly 61 is parallel to the first connecting block 62. The second switch assembly 63 includes a second housing, a second swing switch, and a second contact button. The second housing is disposed on the top of the first connecting block 62, and the second swing switch is rotatably disposed on the side of the second housing near the first housing 611. The first contact button is also disposed on the side of the second housing near the first housing 611, and the first swing switch and the first contact button are spaced apart by a predetermined distance. Those skilled in the art should understand that the first switch assembly 61 can be implemented as a limit switch, meaning the second swing switch can swing a predetermined angle towards the second contact button to contact it.

[0061] Furthermore, the detection device 60 also includes a movable block 64, which is movably placed in the first slide groove 201, and the top of the movable block 64 is fixedly connected to the bottom of the first housing 611 and the first connecting block 62. That is, when the movable block 64 moves laterally a predetermined distance, the first housing 611 and the first connecting block 62 move synchronously.

[0062] It is worth mentioning that the detection device 60 also includes a first driving component 65, which is disposed at the bottom of the sealing door frame 20. The first driving component 65 has a telescopic shaft, which is L-shaped. One end of the telescopic shaft is connected to the first driving component 65, and the other end passes through the second slide groove 202 and is fixedly connected to the bottom of the moving block 64. In addition, the first driving component 65 is configured to drive the telescopic shaft to extend or retract by a predetermined length. That is, when the telescopic shaft extends or retracts by a predetermined length, the end of the telescopic shaft connected to the moving block 64 moves laterally a predetermined distance in the second slide groove 202, while the moving block 64 moves laterally a predetermined distance in the first slide groove 201.

[0063] Additionally, it should be noted that a compression assembly 66 is provided on the side of the unfolding ramp 40 facing the detection device 60. The compression assembly 66 includes a second connecting block 661 and a roller 662. The second connecting block 661 is fixedly connected to the side of the unfolding ramp 40 facing the detection device 60, and the side of the second connecting block 661 near the detection device 60 is rotatably connected to the roller 662. Specifically, the second connecting block 661 has a mounting groove, and the roller 662 is rotatably mounted in the mounting groove via an external shaft. It should also be noted that when the deployable ramp 40 is fully deployed, the user can drive the first drive component 65 via an external terminal to move the moving block 64 backward a predetermined distance. If the connection between the deployable ramp 40 and the ramp retraction mechanism 50 is normal, the first swing switch of the first switch assembly 61 will not contact the roller 662. Then, when the moving block 64 continues to move backward a predetermined distance, the second swing switch of the second switch assembly 63 will contact the roller 662 and be squeezed by the roller 662, thereby causing the second swing switch of the second switch assembly 63 to contact the second contact button, thus allowing the user to... It can be confirmed that there is no problem with the connector between the deployable ramp 40 and the ramp recovery mechanism 50. If there is a problem with the connector between the deployable ramp 40 and the ramp recovery mechanism 50, the connector between the deployable ramp 40 and the ramp recovery mechanism 50 will shift downward by a predetermined distance. At this time, the first swing switch of the first switch assembly 61 will first contact the roller 662 and be subjected to the force of the roller 662, moving a predetermined distance towards the first contact button and contacting the first contact button. This allows the user to quickly confirm that there is a problem with the connector between the deployable ramp 40 and the ramp recovery mechanism 50 and that it needs to be repaired.

[0064] It should be noted that the ramp recovery mechanism 50 is spaced at a predetermined distance from the detection device 60, and a hydraulic assembly 67 is also provided on one side of the ramp recovery mechanism 50. The hydraulic assembly 67 includes an oil tank 671, a pipeline 672, and a connector 673. The oil tank 671 is located on one side of the ramp recovery mechanism 50. Furthermore, the first housing 611 near the oil tank 671 also has an oil inlet, a flow cavity 61101, and an oil outlet. Both the oil inlet and the oil outlet are connected to the flow cavity 61101 and are also connected to the outside. Additionally, an oil pump is provided on one side of the oil tank 671. One end of the pipeline 672 is connected to the oil pump in the oil tank 671, and the other end is connected to the connector 673, which is threadedly connected to the oil inlet. When the hydraulic assembly 67 is in operation, hydraulic oil enters from the inlet and exits from the outlet.

[0065] In addition, the detection device 60 also includes a first telescopic component 68. One end of the first telescopic component 68 is connected to the oil outlet. Specifically, the first telescopic component 68 includes a first connecting pipe 681, a second connecting pipe 682, and a third connecting pipe 683. One end of the first connecting pipe 681 is fixedly connected to the oil outlet, and the other end is fixedly connected to one end of the second connecting pipe 682. One end of the second connecting pipe 682 is movably connected to one end of the third connecting pipe 683. That is, the first connecting pipe 681, the second connecting pipe 682, and the third connecting pipe 683 are all hollow pipes. The first connecting pipe 681 has the same size as the third connecting pipe 683, and the size of the first connecting pipe 681 is larger than the size of the second connecting pipe 682. That is, when the moving block 64 moves a predetermined distance toward the oil tank 671, the end of the second connecting pipe 682 away from the third connecting pipe 683 moves toward the third connecting pipe 683. At the same time, the distance between the first connecting pipe 681 and the second connecting pipe 682 becomes shorter, and vice versa. It should also be noted that the oil is guided to the third connecting pipe 683 through the first connecting pipe 681.

[0066] It should be noted that the detection device 60 further includes a support assembly 69, which includes a support member 691, a fixing member 692, and a second telescopic assembly 693. The support assembly 69 is located between the ramp recovery mechanism 50 and the first chute 201. The fixing member 692 is fixedly connected to the sealing door frame 20. The fixing member 692 has an open mounting cavity on the side away from the first driving component 65, and an assembly hole on the side of the fixing member 692 near the first housing 611. The two ends of the assembly hole are respectively connected to the mounting cavity and the outside. The end of the third connecting pipe 683 away from the second connecting pipe 682 is fixedly connected to the assembly hole, so that the oil placed in the third connecting pipe 683 can be guided to the mounting cavity. It should be noted that the support member 691 has a supporting end and an abutting end, the supporting end being connected to the abutting end, and the cross-sectional dimension of the supporting end being smaller than that of the abutting end. Furthermore, the end of the abutting end facing away from the supporting end is placed within the mounting cavity and located above the assembly hole, and the end of the supporting end facing away from the abutting end contacts the deployable ramp 40 to support it. It is also worth mentioning that the second telescopic assembly 693 is placed within the mounting cavity, and the second telescopic assembly 693 includes a supporting plate and an elastic member. One end of the elastic member is fixedly connected to the bottom wall forming the mounting cavity, and the other end is fixedly connected to the supporting plate, and the end of the abutting end facing away from the supporting end contacts the supporting plate. It is worth mentioning that the deployable ramp 40 unfolds first and then swings at a predetermined angle. The support component 69 is configured to buffer the force, preventing the deployable ramp 40 from swinging down too quickly. Furthermore, it should be noted that if a problem occurs with the connection between the deployable ramp 40 and the ramp recovery mechanism 50 after the ramp 40 has fully unfolded, the first contact switch will activate the oil pump in the oil tank 671. This causes the oil to squeeze the support plate, raising it to a predetermined height, thereby allowing the deployable ramp 40 to... The connector connecting the ramp 40 and the ramp recovery mechanism 50 returns to its predetermined position. It should also be noted that two oppositely arranged sensing units are provided at both ends of the connector connecting the ramp 40 and the ramp recovery mechanism 50. When the first contact switch starts the oil pump of the oil tank 671, the two sensing units are opened synchronously until the connector connecting the ramp 40 and the ramp recovery mechanism 50 returns to its predetermined position. At this time, the oil pump is turned off, which facilitates user maintenance. In addition, the two sensing units and the oil pump are also connected to an external terminal separately.
