Most of the components of this device adopt sheet metal mechanical bending structure and square tube structure, which have high pressure and shock resistance, and are easy to purchase raw materials. Compared with the previous bulky packaging design, it not only saves costs, but also significantly reduces weight.

[0019] Traditional designs without locking mechanisms can cause packaging boxes to vibrate violently during transport, leading to drops and damage. This device, however, features corner locking mechanisms that not only lock the modules in place but also provide corner locking when multiple layers of packaging boxes are transported together, preventing damage from movement during long-distance sea or road transport.

[0020] Compared to previous designs, which lacked a rigid fixing method to secure the vehicle body, leading to damage to vulnerable parts and resulting in replacement costs, this device features a specially designed fixing frame assembly to secure the vehicle itself, firmly holding it within the packaging box, preventing movement and avoiding damage from collisions.

[0021] 3. This device is easy and quick to install. The entire packaging box adopts a snap-fit ​​installation method, with bolt connections for reinforcement. Only 14 bolts are used, saving time and labor costs during installation and improving packaging efficiency. Attached Figure Description
