Description

Technical Field

[0001] The utility model relates to the technical field of sealed cabins, and more specifically, to a sealed cabin and emergency evacuation equipment. Background Art

[0002] When a train needs emergency evacuation, after the train emergency brakes, the trapped people escape in an orderly manner through the evacuation passage. The main evacuation passages of the train are the evacuation doors of the driver's cab at the front and rear ends of the train. Since the passengers are scattered in various carriages, this escape method takes a long time and has low evacuation efficiency. The train can also use the side door evacuation method, and passengers evacuate from the side doors of each carriage. Due to the large height difference between the train and the ground, an evacuation ladder is required to assist in evacuation.

[0003] Prior art Chinese patent CN202411128619.0 discloses a lateral evacuation ladder device for rail transit trains, belonging to the field of rail transit technology. The device comprises: a first drive assembly mounted on the back of the vehicle body, with a hinge connected to the output end of the first drive assembly, wherein the vehicle body is provided with a first lock assembly and a second lock assembly; a bracket connected to the hinge, and the bracket is provided with a first snap assembly and a second snap assembly; a retractable step assembly rotatably connected to the bracket; and a second drive assembly rotatably connected to the bracket at one end and the retractable step assembly at the other end, wherein the plane where the retractable step assembly starts when deployed is higher than the plane where the back of the vehicle body is located. In this prior art, the retractable step assembly, when deployed, has its starting end higher than the plane where the back of the vehicle body is located, reducing the relative height between the top step of the retractable step assembly and the floor surface of the vehicle body, thereby improving the safety of personnel evacuation. However, this evacuation ladder device is exposed to the outside for a long time and lacks protection, making it easily eroded by rain or hit by flying particles during high-speed driving, resulting in a short service life. Utility Model Content

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art evacuation ladder device that is easily damaged due to long-term exposure to the outside. The present invention proposes a sealed cabin and emergency evacuation equipment, which can protect the internal evacuation device and increase the service life of the evacuation equipment.

[0005] To achieve the above-mentioned purpose, a sealed cabin includes a cabin body, a skirt and a rocker mechanism, the cabin body has a accommodating cavity, one side of the cabin body is provided with an opening connected to the accommodating cavity, the skirt can movably cover the opening to close the accommodating cavity, one end of the rocker mechanism is provided in the accommodating cavity, the other end of the rocker mechanism moves along the side wall of the accommodating cavity close to the opening, and the other end of the rocker mechanism is connected to the skirt to drive the skirt to open or close.

[0006] In this technical solution, the cabin is installed at the bottom of the train car and the opening corresponds to the position of the side door. The rocker mechanism can drive the skirt panel to move along an arc, so that the skirt panel opens along the edge of the opening and the inner wall of the accommodating cavity. After the skirt panel is fully opened, it stops at the bottom inner wall of the accommodating cavity to maximize the storage space inside the accommodating cavity. The accommodating cavity can be used to place items for emergency evacuation, such as escape ladders. After the skirt panel is closed, the accommodating cavity forms a closed space, which can prevent rainwater erosion and block flying particles.

[0007] As a preferred solution, the cabin is adapted to the outer shape of the train body, which can reduce wind resistance when the train is running and save energy consumption. The cabin includes a frame and an outer shell. The outer shell is wrapped around the outer periphery of the frame, and the interior of the outer shell forms the accommodating cavity. In order to maximize the storage space inside the accommodating cavity, the side of the frame corresponding to the open position has an arc-shaped structure, and one side of the skirt is an arc-shaped surface adapted to the arc-shaped structure.

[0008] As a preferred solution, in order to make the skirt panel move along an arc trajectory, the rocker mechanism includes a rotating rod and a first telescopic structure, one end of the rotating rod and the first telescopic structure are respectively rotatably connected to the upper inner wall of the frame near the shell, wherein the first telescopic structure and one end of the rotating rod are arranged from near to far relative to the opening position, the other end of the rotating rod is fixed to the edge side of the skirt panel, and the other end of the rotating rod moves along the length direction of the arc structure, and a connecting piece is fixed to the position of the rotating rod near the skirt panel, the telescopic end of the first telescopic structure is rotatably connected to the connecting piece, and a distance is left between the rotating rod and the first telescopic structure. When the telescopic end of the first telescopic structure is extended, the rotating rod is driven to rotate with its upper end as the axis, and the lower end of the rotating rod moves along the arc trajectory, thereby driving the skirt panel to open downward along the arc trajectory; when the telescopic end of the first telescopic structure is retracted, the rotating rod is driven to rotate in the opposite direction, thereby driving the skirt panel to close upward along the arc trajectory. After the skirt panel is closed, its edge abuts against the shell at the opening, and the sealing is strong.

[0009] As a preferred solution, two rotating rods and two first telescopic structures are respectively provided, and the two rotating rods and the two first telescopic structures are respectively arranged on both sides of the opening, so as to avoid interference with the use of emergency evacuation items inside the accommodating cavity and achieve high space utilization.

[0010] As a preferred solution, in order to ensure that the skirt panel is opened into place, the inner wall surface of the shell is provided with a first travel switch electrically connected to the first telescopic structure, and the first travel switch corresponds to the position of the rotating rod when the skirt panel is opened. During the opening process of the skirt panel, when one side of the rotating rod touches the first travel switch, the first telescopic structure stops working.

[0011] As a preferred solution, in order to enable one side of the rotating rod to smoothly abut the first travel switch, one side of the connecting member is connected to an abutting member for triggering the first travel switch, and the abutting member is adapted to the first travel switch structure.

[0012] As a preferred solution, in order to ensure that the skirt panel is closed in place, a second travel switch electrically connected to the first telescopic structure is provided on the upper side of the frame near the opening. The second travel switch corresponds to the position of the skirt panel when the skirt panel is closed. During the closing process of the skirt panel, when the upper part of the skirt panel abuts against the second travel switch, the first telescopic structure stops working.

[0013] As a preferred solution, in order to prevent the skirt panel from opening due to vibration, a rotatably connected hook is provided on the side of the skirt panel facing the accommodating cavity, a knob connected to the hook is provided on the side of the skirt panel away from the accommodating cavity, and a fixing piece cooperating with the hook is provided on the side of the cabin body close to the opening. After the skirt panel is closed, the knob is turned to allow the hook to be locked on the fixing piece to further fix the skirt panel. When the skirt panel needs to be opened, the knob is turned in the opposite direction to disengage the hook from the fixing piece.

[0014] As a preferred solution, in order to enable the cabin to be fixed to the bottom of the train body, a plurality of hanging posts are fixed to the top of the cabin.

[0015] An emergency evacuation device includes the above-mentioned sealed cabin, and also includes an evacuation device and a second telescopic structure placed in the accommodating chamber, the evacuation device is a folding ladder or an inflatable slide, the second telescopic structure is installed on the side wall of the accommodating chamber, and the evacuation device is connected to the telescopic end of the second telescopic structure. When the skirt is opened, the telescopic end of the second telescopic structure extends out of the opening and the evacuation device is deployed; when the skirt is closed, the evacuation device is retracted and the telescopic end of the second telescopic structure is retracted.

[0016] In this technical solution, the emergency evacuation equipment is arranged at the bottom of the train body and corresponds to the side door. When the emergency evacuation equipment is deployed, the knob is first turned to disengage the hook from the fixing part, and the telescopic end of the first telescopic structure extends, driving the skirt panel to open downward until the abutment touches the first travel switch. Then the telescopic end of the second telescopic structure extends and drives the evacuation device to extend out of the cabin. Finally, the evacuation device is deployed to allow passengers to safely evacuate from the side door to the ground; when the emergency evacuation equipment is retracted, the evacuation device is first retracted to its initial form before deployment, the telescopic end of the second telescopic structure drives the evacuation device to retract into the accommodating cavity, the telescopic end of the first telescopic structure retracts to drive the skirt panel to close upward until one side of the skirt panel abuts the second travel switch, and finally the knob is turned to make the hook clamped on the fixing part.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The sealed cabin of the utility model can be used to place items for emergency evacuation. The rocker mechanism drives the skirt to open or close. When the skirt is closed, the enclosed internal space can protect the items inside, prevent rain erosion and block flying particles.

[0019] 2. After the skirt is closed, the cabin forms a sealed space, which can improve the aesthetic effect of the train's appearance and reduce wind resistance during driving to reduce energy consumption.
