[0040] like Figure 1-5 As shown, the present invention discloses an emergency evacuation device for a rail transit vehicle, comprising a door frame 2, a door leaf 1 and a traction mechanism 4, a battery 5 for powering the emergency evacuation device, and an operation control component for controlling the opening and closing of the door leaf 1.

[0041] The door frame 2 includes a door frame side beam 2-1, a door frame cross beam 2-2 and a door frame hinge assembly 2-8. The door frame side beam 2-1 and the door frame cross beam 2-2 are fixed by at least mixed adhesive. The door frame hinge assembly 2-8 includes a swivel bracket shaft 2-8-3 fixed on the door frame 2 and a swivel bracket 2-8-1 rotatably connected to the swivel bracket shaft 2-8-3, so as to realize the flipping and folding of the door frame hinge assembly 2-8 during the opening and recovery process of the door leaf 1. A swivel bearing 2-8-2 is provided between the swivel bracket shaft 2-8-3 and the swivel bracket 2-8-1. The door leaf 1 includes a door leaf side beam 1-1, a door leaf cross beam 1-2, a door leaf reinforcement beam 1-10, an injection molded filler 1-3, a safety glass 1-8 and a door leaf hinge assembly 1-7 cooperating with the door frame hinge assembly 2-8. The door leaf side beam 1-1 and the door leaf cross beam 1-2 are at least fixed by mixed glue, and the door leaf reinforcement beam 1-10 and the door leaf cross beam 1-2 are also at least fixed by mixed glue. The injection molded filler 1-3 is injected into the plane space formed by the door leaf side beam 1-1, the door leaf cross beam 1-2 and the door leaf reinforcement beam 1-10 through a mold, and is naturally bonded and fixed thereto, thereby forming an overall frame of the door leaf 1. The safety glass 1-8 is formed as a whole with the door leaf 1 through a sealing strip. The door leaf hinge assembly 1-7 includes a hinge mounting plate 1-7-2 fixed on the door leaf 1 and a hinge connecting plate 1-7-3 rotatably connected to the hinge mounting plate 1-7-2, so as to realize the flipping and folding of the door leaf hinge assembly 1-7 during the opening and retracting process of the door leaf 1. A hinge bearing assembly 1-7-1 is provided between the hinge mounting plate 1-7-2 and the hinge connecting plate 1-7-3. The door leaf 1 is provided with a ramp slide 1-5 and a ramp plate 1-4 embedded in the ramp slide 1-5. The ramp slide 1-5 is C-shaped and has rollers 1-5-3 on the inner wall, including a slide longitudinal beam plate 1-5-1, a slide cross beam plate 1-5-2 and a slide end beam plate 1-5-4. The ramp plate 1-4 can extend from or retract into the ramp slide 1-5 through the rollers 1-5-3, and when extended, it can extend the end of the door leaf 1 for evacuating passengers. In addition, a locking structure can be provided at the end of the door leaf 1 to fix the ramp plate 1-4 relative to the door leaf 1, providing a safe and stable evacuation channel for passengers.

[0042] The traction mechanism 4 includes a motor 4-1, a coupling 4-2, a storage drum 4-3, a cable 3 and a mounting hanger 4-5 which are connected in sequence. The storage drum 4-3 has a storage drum connecting shaft 4-4, and the cable 3 is wound on the storage drum 4-3. One end of the storage drum connecting shaft 4-4 is connected to the motor 4-1 through the coupling 4-2, and the other end is rollingly connected to the mounting hanger 4-6 through the hanger bearing 4-5. One end of the cable 3 is fixedly connected to the storage drum 4-3, and the other end is fixedly connected to the door leaf side beam 1-1, which mainly plays the role of bearing the gravity of the door leaf 1 and the gravity of the passenger when the door leaf 1 is unfolded, and the pulling effect when the door leaf 1 is recovered. During the recovery process of the door leaf 1, the motor 4-1 in the traction mechanism 4 receives the corresponding signal sent by the operation control component, drives the storage drum 4-3 to stably rotate the recovery cable 3 at a certain speed, so as to recover the door leaf 1 to the closed position. When the door leaf 1 is in a closed state, the inductive magnetic sheet 8 on the door frame 2 and the inductive magnetic sheet 8 on the door leaf 1 are meshed together, and a closed position signal is transmitted to the operation control component through an internally integrated sensor.

[0043] The door frame 2 also includes a lock block assembly, which includes a lock block 2-4, a lock block connecting line 2-5, an emergency unlocking connecting assembly 2-6, and an emergency unlocking rotating handle 2-7. The lock block 2-4 is integrated on the inner side of the door frame side beam 2-1, the inner end of the lock block 2-4 is connected to the lock block connecting line 2-5, the cable block connecting line 2-5 is connected to the emergency unlocking connecting assembly 2-6, and the emergency unlocking connecting assembly 2-6 is connected to the emergency unlocking rotating handle 2-7. The lock block 2-4 can automatically pop out when not subjected to external force, and can passively retract when subjected to external force. The door leaf 1 has a locking structure that cooperates with the lock block 2-4. Under normal circumstances, the lock block 2-4 is in a pop-up state and can buckle the door leaf 1. When an emergency situation requires the door leaf 1 to be opened, the emergency unlocking rotary handle 2-7 is operated, and the lock block 2-4 is mechanically translated to both sides of the door frame 2 through the emergency unlocking connection assembly 2-6 and the lock block connection line 2-5, so that the door leaf 1 is completely unlocked and opened. The pop-up end of the lock block 2-4 has an arc-shaped chamfer. During the recovery process of the door leaf 1, the door leaf side beam 1-1 squeezes the lock block 2-4 into the door frame side beam 2-1 through the arc-shaped chamfer. When the door leaf 1 is recovered to a certain position, the lock block 2-4 automatically pops out, buckles the door leaf 1, and mechanically locks the door leaf 1.

[0044] The door frame 2 and the door leaf 1 are also provided with a door frame induction magnetic sheet assembly and a door leaf induction magnetic sheet assembly, respectively. The door frame induction magnetic sheet assembly includes an induction magnetic sheet 8 integrated on the inner side of the door frame side beam 2-1 and the door frame cross beam 2-2, and the door leaf induction magnetic sheet assembly includes an induction magnetic sheet 8 integrated on the inner side of the door leaf side beam 1-1 and the door leaf cross beam 1-2. The induction magnetic sheet 8 is integrated with a sensor to monitor the opening and closing state of the door leaf 1 during operation at any time, and transmit the state signal to the operation control component to ensure the completeness and completeness of the entire set of emergency evacuation devices at all times. The induction magnetic sheet 8 and the sensor are connected to the battery 5 and the operation control component through a connecting line. During the operation of the vehicle, the door leaf 1 is in a closed state, and the induction magnetic sheet 8 on the door frame 2 and the induction magnetic sheet 8 on the door leaf 1 are tightly meshed together by the power supply of the battery 5 and the control of the operation control component. In this state, even if the emergency unlocking rotary handle 2-7 is operated, the door leaf 1 will not open, thereby ensuring that the door leaf 1 will not be opened due to the passenger's misoperation of the mechanical lock, thereby ensuring the safety of the passengers. When the door leaf 1 needs to be opened in an emergency, the battery 5 is powered off, and the induction magnetic sheet 8 on the door frame 2 and the induction magnetic sheet 8 on the door leaf 1 receive the control signal from the operation control component and release each other. In this state, the emergency unlocking rotary handle 2-7 can be operated to open the door leaf. The emergency evacuation device is provided with mechanical and electrical double-layer protection measures, and its safety and integrity can be ensured by setting the induction magnetic sheet 8 and the lock block assembly.

[0045] The storage battery 5 mainly provides electric energy for the motor 4 - 1 and the induction magnetic sheet 8 during the driving of the vehicle, thereby ensuring the safety and reliability of the entire emergency evacuation device.

[0046] The door frame 2 and the door leaf 1 are also provided with sealing frames 7 that match each other, which together ensure the sealing requirements of the entire emergency evacuation device.

[0047] The door frame 2, the door leaf 1, the ramp plate 1-4 and the ramp slide 1-5 are all made of polymer materials. Among them, the slide longitudinal beam plate 1-5-1, the slide cross beam plate 1-5-2 and the slide end beam plate 1-5-4 in the ramp slide 1-5 are all made of polymer materials and bonded by a specific mixed adhesive. The safety glass 1-8 is a polymer hollow safety glass, and the cable 3 is also made of polymer material injection molding.

[0048] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
