DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 1 , Figure 2As shown, the present invention provides a roof fire blanket, comprising an upper cover 1, a base 2, a control panel 7, a fire blanket 8 and an ejection device 3 for deploying the fire blanket 8, wherein the base 2 is mounted on the top of the vehicle, the upper cover 1 is buckled on the base 2, the fire blanket 8 is folded in the upper cover 1, the center portion of which is fixedly connected to the base 2, and the four corners are connected with the ejection device 3, the ejection device 3 is a spring-driven ejection device, an electric push rod 5 is connected between the base 2 and the upper cover 1, a fire detector 10 is arranged on the outer side of the upper cover 1, the fire detector 10, the control panel 7 and the electric push rod 5 are electrically connected to form a control circuit, and a protective device for triggering the ejection device is connected between the inner upper wall of the upper cover 1 and the ejection device 3 Safety unlocking rope 6; wherein, the control panel 7 can be set to manual and automatic modes, and the two modes are switched by switching switches as needed. In automatic mode, the control panel 7 receives the signal of the fire detector 10, controls the action of the electric push rod 5 through the relay, and then raises the top cover 1, and at the same time, the safety unlocking rope 6 triggers the ejection device 3, and the fire blanket 8 is deployed; during the driving process of the vehicle, the automatic deployment of the fire blanket 8 may cause danger, so it is necessary to switch to manual mode. In manual mode, the action of the electric push rod 5 is not controlled by the signal of the fire detector 10, and the fire detector 10 only plays an alarm role. The user or driver controls the action of the electric push rod 5 through a button switch or a remote control switch according to the alarm signal.

[0017] Further, such as Figure 3 As shown, in this embodiment, the ejection device 3 includes an ejection device housing 11, an ejection push rod 14 and an ejection ball 12. The ejection push rod 14 is installed in the ejection device housing 11 and a compression spring 16 is connected to the ejection device housing 11. One end of the ejection push rod 14 extends out of the bottom of the ejection device housing 11, and the other end contacts the ejection ball 12. The end of the ejection push rod 14 extending out of the bottom of the ejection device housing 11 is provided with a pin hole, and a safety pin 18 is inserted into the pin hole. The safety unlocking pull rope 6 is connected to the safety pin 18. The ejection ball 12 is connected to a corner of the fire blanket 8 through the connecting ring 4; the ejection ball 12 is provided with an ejection ball connecting ring hole 13, and the connecting ring 4 is movably connected to the ejection ball 12 through the ejection ball connecting ring hole 13. The side wall of the ejection device housing 11 is provided with a slot 11a for cooperating with the movement of the connecting ring 4.

[0018] When the top cover 1 is raised, the safety unlocking pull rope 6 pulls the safety pin 18 to disengage the safety pin 18 from the pin hole at the bottom of the ejection push rod 14, and the compression spring 16 causes the ejection push rod 14 to pop out. The ejection push rod 14 pushes the ejection ball 12 to pop out, and the ejection ball 12 deploys the fire blanket 8 through the connecting ring 4.

[0019] Furthermore, the deployment direction of the roof fire blanket is controlled by a guide tube. A guide tube 15 is provided in the ejection device housing 11, and an ejection push rod 14 is slidably installed on the inner wall of the guide tube 15. At the same time, the ejection device housing 11 plays a role similar to a gun barrel. The ejection push rod 14 pushes the ejection ball 12 to accelerate in the ejection device housing 11. After the ejection ball 12 leaves the ejection device housing 11, it continues to deploy the fire blanket 8 under the action of inertia.

[0020] Furthermore, in the present embodiment, there are four groups of ejection devices 3, which are arranged along the diagonal direction of the fire blanket 8. The four corners of the fire blanket 8 are folded upward and connected to the ejection ball 12 through the connecting ring 4 to ensure that the fire blanket 8 can be quickly deployed to cover the vehicle and the surrounding area.

[0021] Further, such as Figure 4 As shown, in this embodiment, the fire detector 10 is a photosensitive probe, also called a photosensitive fire detector, and the photosensitive probes are symmetrically arranged on both sides of the upper cover 1; Figure 5 The perspective of the light sensing probe is shown. In this embodiment, the light sensing probe is preferably an ultraviolet flame detector, which can eliminate interference factors such as sunlight and light. An input and output module is provided on the control board 7. The input end of the input and output module is connected to the ultraviolet flame detector, and the output end controls the action of the electric push rod 5 through a relay. At the same time, a wireless module can also be set on the control board 7. In manual mode, the user can control the deployment of the fire blanket 8 through a mobile phone or other network terminals as needed. The ultraviolet flame detector and control board in this embodiment are all existing finished products, such as JTG-ZW-G1B ultraviolet flame detector, GST-LD-8301, etc. The working principle and wiring method of the specific device are not repeated here.

[0022] Furthermore, in this embodiment, the base 2 is installed on the top of the vehicle through the mounting bracket 9, and a mounting plate 17 is provided on the ejection device 3. The mounting plate 17 is bolted to the mounting bracket 9. The fire blanket 8, the base plate 2 and the ejection device 3 are fixed to the roof luggage rack through the mounting bracket 9 to ensure their stability.

[0023] Furthermore, the material of the fire blanket 8 is a flame retardant material, such as ceramic fiber, carbon fiber or high oxygen silicon material, such as Figure 6 As shown, the area of ​​the fire blanket 8 after being unfolded covers the entire vehicle body; at the same time, the ejection ball 12 makes the fire blanket 8 fit and wrap the vehicle body under the action of gravity.

[0024] Installation and use methods and working process: The device of the present invention is fixed to the luggage rack on the roof by bolts through the mounting frame to ensure its stability; and various components of the fire blanket are regularly checked to ensure that they work normally.

[0025] When a fire occurs when the vehicle is parked, the control panel 7 receives a signal from the fire detector 10 and controls the electric push rod 5 to move through a relay, thereby raising the top cover 1. The safety unlocking pull rope 6 pulls the safety pin 18 to disengage the safety pin 18 from the pin hole at the bottom of the ejection push rod 14. The compression spring 16 ejects the ejection push rod 14, and the ejection push rod 14 pushes the ejection ball 12 to eject. The ejection ball 12 deploys the fire blanket 8 through the connecting ring 4, effectively protecting the vehicle and the surrounding area and ensuring the safety of personnel and property.

[0026] When the vehicle is driving, it is switched to manual mode, and the user or driver controls the electric push rod 5 to move through a button switch or a remote control switch after receiving the alarm model.
