After the earthquake rescue time is very tight, the traditional rescue vehicles need to wait for the road to be restored to enter the disaster area to rescue, which leads to the implementation of timely and effective rescue in the rescue of the golden time.

Qué te inspiró

Over the last decade, earthquakes of varying degrees of severity have become more and more frequent around the world, resulting in a very high number of deaths and injuries to people and property. We see rescue vehicles waiting in line at the entrance of the disaster area, and we hope that these vehicles can enter the disaster area in time for rescue. However, the transportation of rescue vehicles and materials has always been a problem that cannot be ignored in earthquake rescue. With the development of drone technology and battery power technology, we wonder if these two technologies can be applied to rescue vehicles.

Cómo funciona

The vehicle is specially designed with extended linkage, dual springs and single side movable shock absorbers to withstand high altitude free fall impacts and adapt to complex terrains such as collapsed rubble. The vehicle body is made of titanium alloy and carbon fiber composite materials to ensure that the vehicle can withstand the impact during the airdrop process, and at the same time reduce the weight to adapt to a variety of transport carriers. The vehicle supports rapid deployment and recovery of parachutes to ensure airdrop to the target area. Integrates infrared thermal imaging, 3D terrain scanning radar, ultrasonic obstacle detection, and high-definition cameras to build real-time models of the disaster area and plan the optimal rescue path. Establish emergency communication network through mobile signal base station to realize remote human-machine interaction. The cargo hopper can carry medical kits, breaking tools and other key materials.

Proceso de diseño

When our team developed the shock absorber system for rescue vehicles, we mainly did these tasks: first, we studied all the common rescue vehicle shock absorbers on the market and found that they bumped a lot when encountering complicated terrain. So we thought of a new way - to add a longer linkage to the shock absorber, and also installed two springs of different hardness, so that the vehicle can remain stable in different road conditions. Then we hand-drew the appearance of the vehicle with a pencil, focusing on the design of the tilt angle of the front and rear of the car, so that the car is not easy to knock the chassis up and down the slope. Then we used 3D modeling software to draw the entire frame, and tested the strength of the frame through computer simulation to ensure that it would not be deformed even under maximum load. In order to visualize it more, we also used a 3D printer to print out the key parts. The computer software helped a lot in the whole process. Not only did we build a digital model of the vehicle, but we were also able to simulate how it would perform in a rubble environment.

Qué lo hace diferente

While the shock absorbers of ordinary rescue vehicles mainly cope with ordinary road bumps, the DAWN specializes in dealing with airdrop falls and debris terrain. Its shock absorber linkage is longer than that of ordinary vehicles, which can disperse the impact force at the moment of airdrop landing, together with two springs, one soft and one hard - the soft one absorbs the impact of the fall, and the hard one supports the subsequent complex terrain. While ordinary rescue vehicles rely on manual inspection of debris, the car is equipped with infrared, radar and ultrasonic detectors. Infrared can find body temperature, radar penetrates rubble to find gaps, ultrasonic mapping of terrain height difference, three in one is like a vehicle with perspective glasses. This is equivalent to a vehicle with an invisible reconnaissance team, remote control can also clearly “see” the situation behind the obstacles.

Planes para el futuro

In the future, we plan to further integrate the UAV cooperative system with 5G communication, realize the combination with artificial intelligence, real-time monitoring of a wider range of disaster areas and multi-vehicle linkage, and form an “air-ground integrated” rescue network.
