The determination mechanism includes a collision detection portion and a pressure sensor 13 provided in the second housing 5. The collision detecting section is used for detecting whether the vehicle collides, and the airbag can be ejected after the vehicle collides, for example, using the conventional technology. The pressure sensor 13 is used for monitoring the pressure condition in the second casing 5, under normal conditions, the pressure in the second casing 5 is in a constant working pressure range, when the vehicle burns, the high temperature generated by the combustion can be absorbed by the liquid carbon dioxide 9 in the second casing 5 so that the pressure in the second casing 5 is rapidly increased in a short time, and when the pressure in the second casing 5 detected by the pressure sensor 13 exceeds a set first pressure threshold Y1, the controller controls the blasting portion 11 to work.
It should be noted that, when the electrical component 1 in the third casing 8 works, heat is generated, and after the heat is conducted to the third casing 8, the heat can be absorbed by the liquid carbon dioxide 9 wrapped outside the third casing 8, so as to realize efficient cooling of the electrical component 1. The liquid carbon dioxide 9 absorbs heat generated by the operation of the electrical component 1 and then gasifies, so that the pressure in the second shell 5 slowly rises.
The second housing 5 is provided with a connecting pipe 20, the connecting pipe 20 is provided with a valve 21, and the end of the connecting pipe 20 is communicated with the interior of the second housing 5. When no car accident occurs, the pressure sensor 13 detects that the pressure in the second casing 5 reaches the second pressure threshold Y2, at this time, the pressure in the second casing 5 is mainly increased by heat generated by the operation of the electrical component 1 in the third casing 8 and the ambient temperature, so that the liquid carbon dioxide 9 is partially gasified, at this time, the controller opens the valve 21 to realize pressure relief in the second casing 5, and ensure that the pressure in the second casing 5 is in a normal range. In this embodiment, the connecting pipe 20 is disposed on the spike 41.
The bottom of first casing 3 is provided with the weighing portion that is used for measuring the whole weight of second casing 5, and the weighing portion can monitor the whole weight of second casing 5 dynamically, especially the volume of liquid carbon dioxide 9 in the second casing 5, when the weight of liquid carbon dioxide 9 reduces to weight threshold W1, the controller sends out and reminds, needs to fill liquid carbon dioxide 9 in the second casing 5.
Alternatively, in order to monitor the remaining amount of the liquid carbon dioxide 9 in the second housing 5, a liquid level sensor is provided in the second housing 5, so that the remaining amount of the liquid carbon dioxide 9 is monitored. When the liquid level sensor detects that the residual amount of the liquid carbon dioxide 9 in the second shell 5 is reduced to a liquid level threshold value V1, the controller sends out a prompt, and the liquid carbon dioxide 9 needs to be filled into the second shell 5.
An external connection wire 2 is provided at one side of the second housing 5, and a sealing part 6 is provided at an end of the external connection wire 2. The buffer connecting piece 7 is arranged between the inner walls of the third shell 8 and the second shell 5, on one hand, the buffer connecting piece 7 can reduce the influence of jolt of a vehicle in the running process on the electric appliance component 1 in the third shell 8, and on the other hand, the contact area between the third shell 8 in the second shell 5 and the liquid carbon dioxide 9 can be increased, so that the electric appliance component 1 in the third shell 8 is cooled. In this example, six sides of the third housing 8 are all connected with the inner wall of the second housing 5 through the buffer connection piece 7, and the buffer connection piece 7 is made of rubber and plastic materials. The electrical component 1 is fixed in the third shell 8, heat conduction silicone grease is arranged between the inner wall of the third shell 8 and the electrical component 1, heat generated by the operation of the electrical component 1 is conveniently conducted to the third shell 8, and the joint of the third shell 8 and the electrical component 1 is made of metal materials. An internal connecting wire 14 is arranged between the third shell 8 and the second shell 5, and the internal connecting wire 14 is connected with the external connecting wire 2, so that the connection and communication between the electrical component 1 and other external components are realized.
It can be appreciated that the third casing 8 is further provided with a storage battery and a positioning device, and when the second casing 5 pops out of the first casing 3, the positioning device can facilitate the searching of the personnel.
Referring to fig. 1-5, in a normal state, the second housing 5 is filled with liquid carbon dioxide 9 and then sealed, and the pressure in the second housing 5 is 6-10MPa, and in this application, the pressure in the second housing 5 is 8.5MPa in the normal state. The heat generated by the operation of the electric appliance component 1 is absorbed by the liquid carbon dioxide 9 in the second shell 5 after being transmitted to the third shell 8, so that the electric appliance component 1 is cooled. In this embodiment, when no car accident occurs, the pressure sensor 13 detects that the pressure in the second housing 5 reaches the second pressure threshold Y2 of 9.5MPa, the valve 21 is opened, the pressure in the second housing 5 is relieved, and after the pressure in the second housing 5 returns to 8.5MPa, the valve 21 is closed. Opening the valve 21 to release pressure in the second housing 5 can reduce the liquid carbon dioxide 9 in the second housing 5, and when the residual amount of the liquid carbon dioxide 9 in the second housing 5 is less, the controller sends a prompt. When the vehicle collides, the airbag of the vehicle is ejected, and it can be determined that the vehicle has collided, and if the pressure sensor 13 detects that the pressure value in the second housing 5 is rapidly increased in a short time, it is determined that the vehicle burns after the collision. In this embodiment, when the pressure in the second casing 5 detected by the pressure sensor 13 exceeds the set first pressure threshold Y1, the controller controls the bursting part 11 to operate, so as to eject the second casing 5 out of the first casing 3, where the first pressure threshold Y1 is 12MPa, and the pressure change time is 1 hour. When the second housing 5 is ejected out of the first housing 3 under the action of the ejecting mechanism, the protrusion 52 is disposed at the bottom end of the second housing 5, and the liquid carbon dioxide 9 is ejected downward from the protrusion 52 after being gasified, and in the process of moving the second housing 5 upward, the gravity center of the second housing 5 is changed due to the fluidity of the liquid carbon dioxide 9, so that the second housing 5 is inclined, and finally the second housing 5 is far away from the vehicle.
It should be noted that the second housing 5 is filled with liquid carbon dioxide 9, and in other embodiments not shown, the liquid carbon dioxide 9 may be replaced by other liquid flame retardants.
Further, a carbon dioxide compressor may be provided in the vehicle, and when the remaining amount of liquid carbon dioxide is insufficient, liquid carbon dioxide generated by the carbon dioxide compressor is injected into the second housing 5.
Embodiment two: referring to fig. 6-10, the difference between the present embodiment and the first embodiment is that the second housing 5 is provided with a buffer portion 16, a buffer chamber 161 is disposed in the buffer portion 16, and a buffer hole communicating with the buffer chamber 161 is disposed on the surface of the buffer portion 16. The buffer portion 16 can play a role of vibration damping and buffering when the second housing 5 falls to the ground after being ejected by the buffer chamber 161. The buffer hole can enable water to enter the buffer cavity 161 after the second housing 5 falls into water, so that the second housing 5 is prevented from being washed away along with water flow.
