[0002] With the development of automobile transportation and the diversification of transported goods, long truck bodies have emerged. However, as the truck body continues to lengthen, the strength of the side panels has gradually become a key factor that the transportation industry increasingly values, and even directly affects the scope of transportation services. For example, a heavy-duty, impact-resistant truck body disclosed in application number 201620474586.X is novel and simple in design. It features a baseboard on the bottom of the truck body to protect the body, anti-collision iron blocks on the rear side panels to protect the door edges when reversing, making the overall truck body more robust. It also incorporates a bumper on the traditional truck body for impact protection and high safety factor, and a door strip to prevent rainwater backflow when the door is not closed tightly, thus protecting the internal goods.

[0003] However, the above structure cannot be effectively opened on both the front and rear sides during use, which makes it difficult to conveniently load and unload goods, reducing its portability and efficiency. Furthermore, the left side door cannot be opened or closed simultaneously, preventing the left side or both the front and rear sides from being opened at the same time, thus reducing its work efficiency. Therefore, we propose a heavy-duty, crash-resistant truck body. Utility Model Content
