Description

[0001] The utility model belongs to heavy truck protection technical field, specifically, the utility model relates to a cab protection device. BACKGROUND

[0002] In the modern logistics transportation system, heavy trucks play a pivotal role and undertake a large number of long-distance transportation tasks. With the continuous prosperity of the highway transportation industry, the requirements for the cab protection technology of heavy trucks are becoming increasingly stringent. Due to the special nature of the transported goods, the cab of the heavy truck needs to be protected. When the heavy truck is driving, if an accident such as rear-end collision or collision with a guardrail occurs, the cab needs to withstand a large inertial impact force. Due to the large mass and strong inertia of the heavy truck, the energy generated in an instant of collision is extremely high, and the front protection structure of the cab is required to have excellent energy absorption and dispersion capacity to prevent the driver's cabin from being subjected to devastating blows.

[0003] Chinese patent (publication number: 214450788U) discloses a heavy truck cab protection device. The support seat is driven downward by the force of the truck body, which in turn drives the horizontal plate downward. The support seat also drives the two push rods downward, which in turn drives the sliding plug downward, extruding the air in the groove into the air bag. The air bag will swell, providing a buffer force for the downward movement of the horizontal plate, thereby slowing down the forward movement of the truck body and preventing damage to the cab. However, when the heavy truck is subjected to external impact, the driver cannot be completely protected. UTILITY MODEL CONTENTS
