Description

Technical Field

[0001] The invention relates to the technical field of vehicle emergency doors, in particular to a vehicle emergency safety door. Background Art

[0002] As bus safety accidents continue to be exposed, society has paid more and more attention to the safety performance of buses. Safety doors, windows that are easy to open outwards or can be broken with a hammer, and safety roof windows can be used as safe exits for buses.

[0011] Preferably, the electromagnet is electrically connected to the plurality of coil rings.

[0012] Preferably, the permanent magnet is slidably connected to the inner wall of the connecting block.

[0013] Preferably, the spring is arranged on one side of the force-bearing plate, and an opening is arranged on the top of the rubber ring.

[0014] Preferably, one side of the push rod is conical, and the push rod passes through the sealing block and is slidably connected to one side of the tempered glass.

[0015] Working principle: When it is necessary to use the emergency safety door of this vehicle to evacuate the people in the vehicle, when the vehicle body is not tipping over, the user can pull open the anti-touch block and rotate the internal wheel of the anti-touch block, so that the gear plate moves upward as a whole through the meshing connection between the gear and the tooth plate, thereby canceling the lock between the door frame and the door panel, and the motor will be started synchronously, and the lead screw will be driven to rotate through the motor output power, and the telescopic rod will be pushed to gradually lift one side of the support rod through the threaded connection; then, by manpower pushing, the door panel will tilt to both sides of the vehicle body under the influence of gravity, so that the auxiliary rod can contact the ground, and cooperate with the telescopic rod to support the bottom of the door panel. If there is still a height difference between the door panel and the ground, it can be installed under gravity through the wheels on both sides of the telescopic ladder, so that the telescopic ladder can slide outward under the influence of gravity, and evacuate through the guidance of the pointing block, thereby ensuring the height difference with the ground during the evacuation of personnel, and effectively reducing the occurrence of trampling accidents due to people pushing people during the evacuation.

[0016] When the vehicle body is in a tilted state, the user can control the meshing connection between the gear and the tooth plate to disengage the door panel. In the tilted state, the door panel moves inward due to gravity, and the telescopic ladder can also go vertically into the vehicle. Combined with the design of the guide block, the user can use the telescopic ladder and the auxiliary plate, and use the support rod and the auxiliary rod as handrails to help the user climb out of the vehicle body and complete the evacuation.

[0017] When the vehicle body is deformed and the door panel cannot be opened inwards and outwards, the user can pull down the rubber ring so that the spring can push the pushing plate connected to the force-bearing plate to make point-to-face contact with the tempered glass, thereby breaking the tempered glass. The user can then climb out from the tempered glass position to complete the evacuation.

[0018] When the vehicle body is tilted and water enters the interior, as the water flows into the vehicle body, it will enter the assembly block and drive the impeller to rotate. During the rotation, the annular magnet is synchronously driven to rotate in the coil ring through the connecting rod, thereby cutting the magnetic lines of force, thereby generating an induced current, and the electromagnet is energized through an electrical connection, thereby generating suction to drive the permanent magnet to lift, thereby automatically opening the door panel and increasing the emergency evacuation speed of users in the vehicle body.

[0019] The present invention provides a vehicle emergency safety door. It has the following beneficial effects:

[0020] 1. The present invention can improve the emergency evacuation speed of users in various states of the vehicle body through the coordinated use of door panels, telescopic ladders, pointing blocks, motors and other components, and effectively improve the applicability of the vehicle to different emergency environments.

[0021] 2. The present invention uses a motor, an auxiliary rod, a support rod, a toothed plate, a gear and other components in coordination, which can effectively reduce the height difference with the ground during use, reduce the occurrence of additional accidents such as trampling due to crowding during emergency evacuation, and effectively improve order and safety.

[0022] 3. The present invention uses a sealing block, a coil ring, an impeller, an annular magnet and other components in coordination, and can automatically open the door panel for emergency evacuation after water enters the vehicle body, which can effectively improve safety and increase the evacuation speed.

[0023] 4. The present invention uses springs, sealing blocks, push rods, force plates and other components in coordination, so that emergency evacuation can still be performed when the safety door is unusable, thereby increasing emergency evacuation options and improving emergency evacuation effects.
