In order to facilitate the rotation of the connecting rod, an adjusting hole 211 is formed at the middle section of the shaft 21, and the shaft 21 can be conveniently rotated by inserting a pry bar.

The shaft 21 may be cylindrical or rectangular, and in order to rotate the shaft 21, a circular hole may be designed in the middle of the shaft 21, or multiple planes may be provided to facilitate holding the shaft 21 for rotation.

The number of the connecting rod assemblies 20 is four, the four connecting rod assemblies 20 are hinged together through a middle connecting seat (namely, a first connecting seat 10), the other end of each connecting rod assembly 20 is connected to two sides of the underframe 210 through an end connecting seat (namely, a second connecting seat 30), the connecting rod assemblies 20 are connected with the middle connecting seat through a pin shaft A14, the connecting rod assemblies 20 are connected with the end connecting seats through a pin shaft B32, and locking is carried out through locking nuts 24, so that an X-shaped beam structure is formed, and the effect of reinforcing the V-shaped underframe 210 is achieved.

The V-shaped underframe 210 may deform under the action of the passenger compartment and external loads, and at this time, the X-shaped cross beam structure tightens the two sides of the underframe 210, thereby preventing the underframe 210 from deforming and reinforcing the V-shaped underframe 210.

When any one connecting rod assembly 20 of the X-shaped beam structure is damaged, the connecting rod assembly can be detached and replaced independently, the maintenance performance is improved, and the cost is reduced.

Yet another embodiment of the present application provides a body frame 210 assembly for an armored vehicle. The body frame 210 assembly of the armored vehicle comprises a V-shaped vehicle bottom frame 210 and an X-shaped beam structure. The X-shaped beam structure comprises: end connection seats (i.e., second connection seat 30), link assembly 20, intermediate connection seats (i.e., first connection seat 10), and fasteners, such as bolts, nuts, pins (pin a14, pin B32), and the like. The linkage assembly 20 includes a first end 22, a second end 23, a shaft 21, and a lock nut 24.

The X-shaped cross beam structure is horizontally arranged in the V-shaped underframe 210, and one or more groups of X-shaped cross beam structures can be arranged according to actual needs. Two ends of the rod body 21 are respectively provided with threaded sections with opposite rotation directions, and the threaded sections are respectively connected with the first end 22 and the second end 23. Before the first end head 22 and the second end head 23 are installed, the locking nut 24 is screwed into the threaded section, and a circular hole is formed in the middle section of the rod body 21 and used for prying the rod body 21 to rotate. The end connection seats are assembled on two sides of the V-shaped underframe 210 in advance through welding or bolt connection, one end of the connecting rod assembly 20 is connected with the end connection seats, the other end of the connecting rod assembly is connected with the middle connection seats, and the connecting rod assembly 20 is rotatably connected with the end connection seats through a pin shaft B32 and then locked through a locking nut 24. Similarly, the link assembly 20 is pivotally connected to the intermediate connector block by a pin A14 and is locked by a locking nut 24. After the assembly is completed, the length of the link assembly 20 can be adjusted by rotating the links, and when the four link assemblies 20 are adjusted and tightened, the locking nut 24 is reversely screwed out to lock the rod body 21 with the first end 22 and the second end 23, at which time the length of the link assembly 20 is fixed.

When the V-shaped underframe 210 is deformed by an external force, the length of the four link assemblies 20 of the X-beam structure tends to change, but since the length of the four link assemblies 20 is fixed in advance, the V-shaped underframe 210 is deformed and reinforced by the V-shaped underframe 210.

(3) The thread directions of the two ends of the connecting rod assembly 20 are opposite, and the length of the connecting rod assembly 20 can be conveniently adjusted and locked by rotating the rod body 21. Meanwhile, the space in the cabin of the chassis 210 can be saved, arrangement of other parts of the chassis is facilitated, and the maintenance cost is lower.
