Specific embodiment
Below against accompanying drawing, by the description to embodiment, specific embodiment of the present utility model is made detailed further
Thin explanation, with help those skilled in the art inventive concept of the present utility model, technical scheme are had more complete, accurately and
Deep understanding.
Structure of the present utility model as shown in Figure 1, is a kind of electric automobile full aluminum body in white self-clinching nut structure, described
Self-clinching nut 1 main body be cylinder.Screwed hole and this cylinder coaxial line.The basic size of the general screwed hole adopting is
M5 to M8.In electric automobile field, the screwed hole basic size of conventional self-clinching nut is M6.
In order to overcome the defect of prior art, realize carrying out on aluminium alloy extrusions or sheet metal component the installation of parts with tight
Solid goal of the invention, the technical scheme that this utility model is taken is：
As shown in Figure 1 and Figure 2, the full aluminum body in white self-clinching nut structure of electric automobile of the present utility model, in described circle
One end of cylinder, is provided with riveting dome, and the external diameter of described riveting dome is less than described cylindrical diameter；In described riveting
Belling justifies position, and described self-clinching nut 1 is connected with vehicle body aluminium sheet 2 riveting.
Using technique scheme, solve the problems, such as nut cannot projection welding on aluminium plate, realize nut in vehicle body aluminium sheet
On connect and form pressure riveting structure, its stable connection, reliability, bond strength is high, erectility is big, particularly prevents connector
