Problems solved by technology
However, the welding bolts on the market do not have the function of preventing bullets from penetrating, and the through holes used to connect the welding bolts on the draped armor become the weak point of protection. Additional armor protection structures need to be added, resulting in complex structure and increased weight of the vehicle body.

Embodiment Construction
[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0037] refer to figure 1 , figure 2 , a connection structure between draped armor and body frame with bulletproof function, comprising an armor module 1 , a connecting flange 2 and a threaded main body 3 .
[0038] One end of the connecting flange 2 is fixedly connected to the armor module 1 at the joint 4 between the armor module and the connecting flange.
[0039] The connection between the armor module 1 and the connecting flange 2 can be realized by various technological means such as welding, bonding and r...

The invention belongs to the technical field of automobiles, and particularly relates to an extra armor and vehicle body frame connection structure with a bulletproof function. The connection structure comprises an armor module, a connecting flange and a threaded main body, wherein the threaded main body penetrates through a vehicle body metal plate through hole from the vehicle body metal plate side till the connecting flange is attached to the surface of the vehicle body metal plate. The connecting flange and the vehicle body metal plate are welded and fixed with a vehicle body metal plate weld joint through the connecting flange; and a hexagon nut is matched with the threaded main body from the side of the extra armor to fix the extra armor on the vehicle body frame. According to the extra armor and vehicle body frame connection structure with the bulletproof function, the protection performance of the structure can be adjusted according to requirements, the connecting process and the thread specification are the same as those of a conventional welding bolt, and meanwhile, the bulletproof requirement and the thread fastening requirement are met; and the structure is simple, performance is reliable, cost is low, standardization and modularization can be achieved, and the problems existing when an existing connecting structure adopts a common welding bolt are solved.
Description
technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a connection structure between a draped armor and a vehicle body frame with a bulletproof function. Background technique [0002] Special protective vehicles refer to vehicles with dimensions, weight, etc. that exceed the design vehicle limits and special-purpose vehicles, which are specially made or modified and equipped with fixed devices. [0003] Special protective vehicles generally realize special protective functions by adding armor on the body on the basis of ordinary vehicles. The body frame and the draped armor are tightly connected by welding bolts and nuts, so as to realize the installation and fixation of the draped armor and the body frame. However, none of the welded bolts on the market has the function of preventing bullets from penetrating. The through holes used to connect the welded bolts on the draped armor become weak points of protection. Ad...
