Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses when the side collision takes place for the car among the prior art, the side structure of automobile body takes place to largely pour into the problem of deformation, provides a threshold structure and car.
As shown in fig. 1-2, an embodiment of the present invention provides a threshold structure, including:
a rocker outer panel 1, a rocker inner panel 2 and at least one reinforcing panel 3;
the inner side of the threshold outer plate 1 is provided with the threshold inner plate 2; the inner side of the rocker inner panel 2 is provided with at least one reinforcement panel 3.
The utility model discloses a doorsill structure which comprises a doorsill outer plate 1, a doorsill inner plate 2 and at least one reinforcing plate 3; the inner side of the threshold outer plate 1 is provided with the threshold inner plate 2; the inboard of threshold inner panel 2 is provided with at least one reinforcing plate 3, simple structure, intensity is reliable, easily processing, and technology easily realizes, can effectively slow down vehicle striking or cylindricality structure and automobile body and take place the striking when the car takes place side collision accident or side post collision accident, reduces the side structure deformation of automobile body to driver and passenger's the security of the lives and property in the protection car.
The rocker structure meets the requirement of light weight design of the vehicle on resisting deformation of the vehicle body.
Optionally, the rocker outer panel 1 and the rocker inner panel 2 are connected by welding.
Here, the rocker outer panel 1 and the rocker inner panel 2 are welded by spot welding.
