[0002] At present, field rescue vehicles have been widely used in disaster rescue, off-road exploration and other fields. However, there are still many deficiencies in the existing technology when dealing with complex terrains. Most traditional rescue vehicles rely on a single wheeled or tracked structure. Although they have a certain degree of mobility, in muddy, sandy, snowy or uneven mountainous environments, they are prone to insufficient grip, vehicle sinking or slipping; in addition, when existing vehicles face emergencies (such as ground slides or emergency braking), their support and braking systems respond slowly and have poor stability, and it is difficult to quickly provide effective support; to solve the above problems, there is an urgent need for a new type of field rescue vehicle with a more flexible structure that can automatically adjust and adapt to a variety of complex terrains to improve rescue efficiency and ensure personnel safety.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. Enhanced terrain adaptability: The rescue vehicle is equipped with an auxiliary fixing component. Through the linkage design and coordinated use of airbags and auxiliary claws, the vehicle can provide additional support on different terrains (such as muddy, quicksand, or snowy terrains), reducing the risk of getting stuck and improving stability; or enhancing the grip and reducing the risk of getting stuck or overturning.

[0023] 2. Improved vehicle stability: The auxiliary claws of the auxiliary fixing component are designed with the linkage of fixing rods, sliding rods, and claws, enabling the auxiliary claws to be adjusted according to terrain requirements. In case of sudden slippage or backward movement, the auxiliary claws and the fixing rods can quickly stop or fix the vehicle, preventing the vehicle from overturning and ensuring operation safety.

[0024] 3. Optimized support system: The auxiliary support system consists of a rotating frame, a driving component, and a conical head, etc. The ground angle of the rotating frame is adjusted by the first driving component, and the depth of the conical head embedded in the ground is adjusted by the second driving component. The support component can adjust the support angle and the embedding depth according to the terrain, improving the support effect of the vehicle and effectively preventing side overturning or sinking on uneven terrains or soft ground.

[0025] 4. Increased crawler braking ability: An auxiliary braking component is added to the crawler assembly. When the vehicle encounters slope slippage or backward movement, the braking part can quickly abut against the tooth structure of the crawler track. When driving forward normally, the outer surface of the braking part is smooth and will not affect the teeth. When driving backward, the teeth are clamped at the opening of the braking part to prevent the crawler from moving backward, achieving emergency braking, preventing the vehicle from getting out of control, and improving safety.

[0026] 5. Improved rescue efficiency: Through the auxiliary fixing component, the auxiliary support system, and the auxiliary braking component, the vehicle can maintain the best state in various rescue environments, improving the efficiency and reliability of rescue work.

[0027] 6. Enhanced structural durability: A puncture-proof layer (such as Kevlar fiber mesh) is added outside the airbag, which can effectively resist damage to the airbag by sharp objects, improving the durability and service life of the equipment and meeting the long-term operation requirements in complex field environments.
