Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a fireproof automatic door. Background Art

[0002] One of the current car configuration functions is automatic doors, which require no pushing or pulling and no human intervention, freeing your hands and improving the grade of the vehicle and its ease of use.

[0003] When the existing automatic car doors are in use, due to the thin door shell, when a car catches fire, the car door shell will heat up rapidly, causing occupants to be easily burned when escaping or people outside the car are trying to rescue, and the automatic car door cannot be opened, affecting the safety of the people. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that when a fire occurs in a car, the temperature of the car door shell rises sharply, resulting in the inability to open the car automatic door, and proposes a fireproof automatic door.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A fireproof automatic door comprises a door shell, a temperature sensor and a smoke sensor are fixedly connected to the inner wall of one side of the door shell, a plurality of water tanks are fixedly connected to the inner wall of one side of the door shell, a sealing cover is slidably inserted at the bottom of the water tank, a plurality of electric push rods are fixedly connected to the inner wall of one side of the door shell, a connecting rod is fixedly connected to one end of every two electric push rods, one side of the connecting rod is fixedly connected to the sealing cover, a plurality of storage boxes are fixedly connected to the inner wall of one side of the door shell, the storage boxes are located below the water tanks, and a water-soluble film is bonded to the top of the storage boxes.

[0007] Furthermore, two isolation covers are fixedly connected to an inner wall of one side of the door shell, and the two isolation covers respectively cover the outer sides of the temperature sensor and the smoke sensor.

[0008] Furthermore, an outer side of the door shell is fixedly connected with an outer handle.

[0009] Furthermore, a window glass is embedded on one side of the door shell.

[0010] Furthermore, an inner handle and a storage box are fixedly connected to the inner side of the door shell.

[0011] Furthermore, a plurality of through holes are provided on one side of the door shell.

[0012] Furthermore, a sealing strip is sleeved on the door shell.

[0013] The beneficial effects of the utility model are:

[0014] 1. The temperature and smoke are detected by the temperature sensor and the smoke sensor. When the temperature sensor and the smoke sensor detect the temperature rise and smoke, the sealing cover is removed from the bottom of the water tank under the drive of the electric push rod. Then, the water in the water tank falls into the storage box. Then, the sodium polyacrylate solid particles in the storage box absorb water to form a gel that fills the inside of the door shell, thereby cooling the door shell and preventing the door shell from being too hot to avoid scalding the people in the car and rescuers.

[0015] 2. Protect the temperature sensor and smoke sensor with an isolation cover to avoid damage to the temperature sensor and smoke sensor, so as to ensure normal monitoring of the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4A fireproof automatic door comprises a door shell 1, a temperature sensor 4 and a smoke sensor 5 are fixed to the inner wall of one side of the door shell 1 by bolts, the model of the temperature sensor 4 is ATS1-82, the model of the smoke sensor 5 is MQ-2, a plurality of water storage tanks 8 are fixed to the inner wall of one side of the door shell 1 by bolts, water resources are stored in the water storage tanks 8, a sealing cover 9 is slidably inserted at the bottom of the water storage tank 8, a plurality of electric push rods 12 are fixed to the inner wall of one side of the door shell 1 by bolts, one end between every two electric push rods 12 is fixed with a connecting rod 13 by bolts, one side of the connecting rod 13 is fixedly connected to the sealing cover 9, a plurality of storage boxes 10 are fixed to the inner wall of one side of the door shell 1 by bolts, Sodium polyacrylate solid particles are stored in the storage box 10. The storage box 10 is located below the water tank 8. A water-soluble film 11 is bonded to the top of the storage box 10. The temperature and smoke are detected by the temperature sensor 4 and the smoke sensor 5. When the temperature sensor 4 and the smoke sensor 5 detect the temperature rise and smoke, the connecting rod 13 and the sealing cover 9 are moved under the drive of the electric push rod 12, thereby removing the sealing cover 9 from the bottom of the water tank 8. Then, the water in the water tank 8 falls into the storage box 10, and then, the sodium polyacrylate solid particles in the storage box 10 absorb water to form a gel that fills the inside of the door shell 1, thereby cooling the door shell 1 and preventing the door shell 1 from being too hot.

[0023] Two isolation covers 14 are fixed to the inner wall of one side of the door shell 1 by bolts, and the two isolation covers 14 respectively cover the outer sides of the temperature sensor 4 and the smoke sensor 5, and the temperature sensor 4 and the smoke sensor 5 are protected by the isolation covers 14. An outer handle 15 is fixed to the outer side of the door shell 1 by bolts to open the door shell 1 outside the vehicle. A window glass 16 is embedded on one side of the door shell 1, and an inner handle 17 and a storage box 18 are fixed to the inner side of the door shell 1 by bolts. The design of the inner handle 17 is convenient for opening the door shell 1 in the vehicle. A plurality of through holes 19 are provided on one side of the door shell 1, and a sealing strip 20 is sleeved on the door shell 1 to improve the sealing between the door shell 1 and the vehicle.

[0024] Working principle: When in use, the temperature sensor 4, the smoke sensor 5 and the electric push rod 12 are connected to the central control system of the vehicle, and the temperature and smoke are detected by the temperature sensor 4 and the smoke sensor 5. When the temperature sensor 4 and the smoke sensor 5 detect the temperature rise and smoke, the information is transmitted to the central control system, and then the central control system controls the electric push rod 12 to work. Driven by the electric push rod 12, the connecting rod 13 moves, thereby driving the sealing cover 9 to move, and then the sealing cover 9 is removed from the bottom of the water tank 8. Then, the water in the water tank 8 falls on the water-soluble film 11, and the water-soluble film 11 melts and falls into the storage box 10. Then, the sodium polyacrylate solid particles in the storage box 10 absorb water to form a gel that fills the inside of the door shell 1, thereby cooling the door shell 1 and preventing the temperature of the door shell 1 from being too high.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
