Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Example (b):
referring to fig. 2, an integral side panel reinforcement includes a side panel reinforcement body 6, and the side panel reinforcement body 6 has a side panel rear lower outer panel reinforcement portion 61 and a side panel sill reinforcement rear connection portion 62. Namely, the side-wall rear lower outer plate reinforcement 1 and the side-wall threshold reinforcement rear connecting plate 2 in fig. 1 are designed and manufactured into a whole, wherein the side-wall rear lower outer plate reinforcement 61 is used for replacing the side-wall rear lower outer plate reinforcement 1 and realizing a corresponding function, and the side-wall threshold reinforcement rear connecting part 62 is used for replacing the side-wall threshold reinforcement rear connecting plate 2 and realizing a corresponding function.
