[0002] Traditional exhibition vehicles often use welded or one-piece molded frames, which are bulky during transportation, cannot flexibly adjust the spatial layout, resulting in high transportation costs and making modular assembly impossible.

[0003] A search revealed a detachable frame vehicle disclosed in Chinese patent application number 201110028595.8. The device consists of a frame body, a pair of front beams symmetrically arranged on both sides of the front of the frame body, a pair of suspension assemblies symmetrically arranged on both sides of the frame body and located below the rear of the frame body, and a rear beam located at the rear of the frame body. The front beams, the suspension assemblies, and the rear beam are detachably connected to the frame body, and the rear bumper assembly is detachably connected to the rear beam. However, the main beam is relatively long, making movement and transportation inconvenient.

[0004] However, existing patents have the following drawbacks:

[0005] The two main beams of this detachable frame vehicle are quite long and are a single, integral structure without any breaks in the middle. This makes it inconvenient to move and assemble, and prevents modular assembly. Utility Model Content
