[0005] Furthermore, the aluminum alloy profile fixing frame includes a plurality of rectangular tubes and rectangular blocking plates, and the plurality of rectangular tubes form the crossbeams, longitudinal beams and vertical beams of the aluminum alloy profile fixing frame. The crossbeams, longitudinal beams and vertical beams are assembled and welded into the frame part of the aluminum alloy profile fixing frame. The rectangular blocking plates seal the openings of the rectangular tubes. Eight mounting points are distributed on each side of the two longitudinal beams close to the ground, and four mounting points are distributed on each side of the bottom of the two groups of vertical beams symmetrically distributed at the front. Mounting plates are respectively provided at the four bottom corners of the aluminum alloy profile fixing frame. The aluminum alloy profile fixing frame is fixed to the vehicle body floor with bolts through the mounting plates. Aluminum alloy sleeves and rubber pads are provided on the two groups of longitudinal beams on both sides of the upper part of the aluminum alloy profile fixing frame. The aluminum alloy sleeves pass through the bolts connecting the seat assembly and the rectangular tubes. The rubber pads are in direct contact with the seat assembly to buffer and reduce shock and eliminate abnormal noise.

[0006] Furthermore, reinforcing ribs are provided on the upper and lower portions of the aluminum alloy profile fixing frame near the front and rear vertical beams.

[0007] Furthermore, the box body composition includes a panel composition and a bracket composition, the panel composition includes a box door and a box body, the bottom profile of the box door outer frame, the straight section profile of the box upper surrounding beam, the right side profile of the box upper surrounding beam and the box outer door frame profile are welded to form the outer frame of the box door, the box panel and the outer frame are connected by bonding to form the box body, a box door is arranged at the front of the box body composition, the box door includes a box door panel, the box door panel is bonded to the box door frame, a keyless box lock is arranged on the inside of the box door, the box lock comes with a nut, and when it needs to be used, it can be opened by rotating the lock handle on the outside according to the prompt of the switch direction, the hand cover and the keyless box lock are connected to the box door panel, the hand cover fixing plate and the box door by M4 cross slot pan head screws. The frame is assembled into a box door as a whole, and the box door and the box body are flipped and connected by the box flip hinge. The box flip hinge is connected and fastened to the box body by a cross-slot pan head screw. The box door and the box body together form a panel composition. The box mounting seat, the box bracket bottom angle steel and the box bracket vertical angle steel are welded on the internal box panels on both sides of the box body to form a box bracket composition. The box bracket composition and the entire panel composition are assembled into a box composition. The box composition is connected to the aluminum alloy profile fixing frame composition through the box mounting seat in the form of bolts. The panel composition and the bracket composition are connected by M5 hexagon socket countersunk screws, which play a role of connection and fastening. Rubber strips are vertically arranged at the rear of the box compositions on both sides to buffer the gaps and eliminate abnormal noises.

[0008] Furthermore, the holding tray comprises a holding tray handle, which is connected to the holding tray body by welding; the front and rear shock-absorbing pads of the escape ladder placement plate, the shock-absorbing pads of the escape ladder holding tray, and the side rubber pads of the folding ladder holding tray are directly adhered to the inside of the holding tray, and the shock-absorbing pads have a single-sided adhesive backing to play the role of buffering, shock absorption and eliminating abnormal noise;

By pressing the locking rod on the left front of the holding tray with the left hand and pulling the handle of the holding tray with the right hand, the slide can be pulled to the longest state. The holding tray is first connected to the inner slide of the slide assembly through an M5 hexagonal countersunk bolt, and at the same time, the outer slide of the slide assembly is also connected to the aluminum alloy profile fixing frame assembly through an M5 hexagonal countersunk bolt.

[0010] Furthermore, each side of a single slide composed of the slides has 8 mounting points corresponding to the longitudinal beams, and the slides can be freely extended and retracted, with the maximum extension length being 800 mm.

[0011] At present, the escape ladders used in domestic subway and EMU vehicle projects are mostly set in the passenger compartment partition wall or on the vehicle body chassis, and the storage method or installation method mostly adopts a special key locking and unlocking and a strap fixing structure, which makes it impossible for ordinary passengers to access them. The present invention utilizes the lower space of the transverse fixed seat structure to set an inspection door that can be quickly opened by passengers, and adds a tray device that can be pulled out, slid and locked on this basis to realize the self-service access function of the escape ladder, thereby meeting people's needs for safe travel and faster and more convenient emergency protection. When the vehicle adopts unmanned driving mode, if an emergency occurs and passengers need to get off the vehicle urgently, the passengers can quickly operate the escape ladder storage device by themselves to operate the emergency escape ladder. For this reason, a new type of escape ladder storage device has been developed that is simple, convenient, humane and can bring passengers a high-quality riding experience.
