Under the action of the fire blanket 8, the movements of the five groups of "U"-shaped combination rods form a connection. Under the power support of the driving device 1, the driving shaft 202 drives the No. 1 long rod 401 to rotate. Since the No. 1 long rod 401 is connected to the No. 1 short rod 411 and the No. 6 long rod 406 through the corner tube 416, the No. 6 long rod 406 and the No. 1 short rod 411 rotate together. Due to the connection effect of the fire blanket 8, when the "U"-shaped combination rod composed of the No. 1 long rod 401, the No. 6 long rod 406, and the No. 1 short rod 411 rotate to a certain angle, it will drive the No. 2 long rod 402, the No. 7 long rod 407, and the No. 2 short rod 412 to rotate. When the "U"-shaped combination rod composed of the second long rod 402, the seventh long rod 407 and the second short rod 412 rotates to a certain angle, the "U"-shaped combination rod composed of the third long rod 403, the eighth long rod 408 and the third short rod 413 will be driven to rotate, and so on, until the first long rod rotates to the ground position and no longer rotates, the remaining "U"-shaped combination rods also stop rotating, and at this time the fire blanket folding structure 4 is in a tent-like shape, indicating that the vehicle 6 is completely covered by the fire blanket 8. When the driving device 1 is started, the first door 501, the second door 502 and the third door 503 are respectively pushed upward by the first long rod 401, the sixth long rod 406 and the first short rod 411, so the first door 501, the second door 502 and the third door 503 will be fully opened, thereby facilitating the movement of the remaining rods.A smoke sensor 9 is installed directly above the parking space 7. The smoke sensor 9 can detect and send smoke signals in real time. An infrared temperature recognition device 10 is installed above the parking space 7. The infrared temperature recognition device 10 faces one side of the parking space 7. Its scanning range can completely cover the parking space 7 and the area occupied by the vehicle 6. It can monitor and send temperature signals in real time. A control device 11 is installed next to the infrared temperature recognition device 10. The control device 11 is installed away from the parking space 7 to prevent damage to the control device 11 in the event of a fire. The drive device 1, the smoke sensor 9, the infrared temperature recognition device 10 and the control device 11 are electrically connected. The control device 11 can receive smoke signals from the smoke sensor 9 and the infrared temperature recognition device 10. The control device 11 can send fire alarm information to the staff, so that the staff can receive the information and respond in time and arrive at the fire scene in time. When a fire occurs, the smoke sensor 9 detects the smoke signal and feeds it back to the control device 11. The control device 11 also receives the high temperature alarm information of the infrared temperature recognition device 10. The control device 11 sends a start signal to the drive device 1. The drive device 1 immediately responds and operates the motor 101 to provide power support for the fire blanket folding structure 4. Under the rotation of multiple sets of "U"-shaped combination rods, the fire blanket 8 is fully unfolded to completely cover the signal vehicle 6 to isolate the air and quickly extinguish the fire.

[0022] In the description of the present invention, the number of the rods is not limited to the described number. For example, there are only ten long rods in the description of the present invention, and there are five groups of "U"-shaped combination rods in the description of the present invention. However, in actual use, the operator can increase or decrease the number of rods according to the specific circumstances, and is not limited to the number described in the present invention. The operator can also appropriately modify the length of the rods according to the specific circumstances to suit the use in multiple environments.

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] A method of using and working principle of an automatic covering fire extinguishing device set in a car parking space: 1) The smoke sensor 9 and the infrared temperature recognition device 10 perform smoke detection and temperature detection on the indicated vehicle 6 parked in the parking space 7. When a fire occurs, the smoke sensor 9 detects the smoke signal and feeds it back to the control device 11. At the same time, the control device 11 receives the high temperature alarm information from the infrared temperature recognition device 10. The control device 11 sends a start signal to the drive device 1 and sends a fire alarm information to the staff.

[0026] 2) After the control device 11 sends a start signal to the driving device 1 , the driving device 1 immediately responds and operates the motor 101 to provide power support for the fire blanket folding structure 4 .

[0027] 3) After the motor 101 is started, the driving shaft 202 drives the "U"-shaped combined rod composed of the first long rod 401, the sixth long rod 406, and the first short rod 411 to rotate, and the one-way spring door 5 is automatically opened.

[0028] 4) Due to the connection function of the fire blanket 8, the "U"-shaped combination rod composed of the second long rod 402, the seventh long rod 407, and the second short rod 412 rotates, and so on, until the first group of "U"-shaped combination rods rotates to the ground position, the motor 101 stops running, and each group of "U"-shaped combination rods also stops rotating. At this time, the fire blanket folding structure 4 is in a tent-like shape, indicating that the vehicle 6 is completely covered by the fire blanket 8 to isolate the air and quickly extinguish the fire.
