Description

Fire truck with warning projection

This creative department has a fire-fighting vehicle structure that can use the smoke at the scene of the fire as the first projection screen to facilitate the projection of the warning light signal.

At present, due to the chaos in the fire scene, when the traffic control of personnel and vehicles is not good, it will affect the disaster relief, and even cause traffic congestion, making it difficult for fire trucks or ambulances to enter the fire scene. .

Therefore, there is a new patent No. M438990 "Triangle Warning Stereo Projection Device" announced by the Republic of China on October 11, 101. It is disclosed: it includes a rear bumper projection hole, a switch button, a row of computers, and a control. And a holographic projector. When the vehicle is temporarily parked, as long as the switch button is pressed, the driving computer transmits the signal to the controller after receiving the signal; the controller will induce the holographic projector to generate a stereoscopic stereo projection according to the instruction. . The main reason is to provide the driver with a 3D triangular warning stereo image at the set distance after the vehicle is temporarily parked, so as to improve the safety and convenience of parking.

The patented front projection image is projected on the rear of the vehicle. In order not to affect the rear driver, the projection height and the projection distance are limited. Only tens of meters of visibility can be recognized, and there is no large-scale or long-distance distance. It is identifiable, so it is still too close to the projection distance, and a large number of vehicles approach the scene of the fire, only to find that the front is not accessible, so it will still cause a large number of vehicle jams.

In addition, there is a new type of "Missing device with warning function" announced by the Republic of China on April 21, 102, which discloses: a device body having one or more light source devices thereon, the light source device One or more graphics can be projected; a driving circuit, which can be driven by a mains, a battery or a battery, the driving circuit is electrically connected to the main body of the device; and a switching device electrically connected to the driving circuit, The light source device for opening and closing the main body of the device; by the above device, the user can use it alone or can be disposed on the vehicle and other devices, and the light source device can be turned on or off by the switch device to be turned on or off, thereby increasing Safety at night or increase the brightness of the day, and can enhance the individual identification through the different patterns illuminated. Moreover, the different patterns on the lens of the light source device or the different patterns on the lamp cover can also send the user's needs. Communicate the message to others and achieve a safe and beautiful appearance.

However, the patent is only for projecting light horizontally toward the circumference of the vehicle. It also has only tens of meters of visibility, and does not have wide-range or long-distance visibility. Therefore, it is still projected. The distance is too close, causing a large number of vehicles to be unclear and still close to the scene of the fire and causing blockages, so it is still not ideal for use.

Accordingly, in view of the warning device projected by the vehicle at the current fire scene, the above disadvantages are obtained. Therefore, the present invention provides a fire truck with a warning projection function, which utilizes a smoke generated by a fire scene as a first projection screen, and the fire truck with a warning projection function is provided with a vehicle body; at least one projection unit is disposed at In the vehicle body, the projection unit is configured to project a warning light signal upwardly, the warning light signal is projected on the first projection screen; a control unit is disposed on the vehicle body, and the control unit is connected to the signal A projection unit for inputting or changing the content of the warning light signal.
