Description

Technical Field

[0001] The invention relates to the technical field of automobile instrument panels, and in particular to a clamping device for an instrument panel body and a front panel metal. Background Art

[0002] With the overlap form of the dash cover and the air chamber cover of the automobile body structure, and the different spatial structures of the instrument panel styling surface and the dash sheet metal, there are also certain challenges to the clamping and fixing method of the dashboard body and the dash, and not a single clamping form is suitable for all dash structures. There are two conventional methods. One is to make a clamping groove structure on the dashboard, which is clamped at the edge of the welding stopper of the air chamber cover and the dash panel; the other is to weld a bracket on the dash panel, and set a pin on the dashboard to insert into the square hole of the welding bracket. Because the distance from the edge of the welding stopper to the dashboard assembly and the dash panel is quite different, if it is clamped at the upper edge of the stopper, the dashboard assembly and the dash panel will have more hanging parts, and the front edge of the dashboard will have the risk of shaking and heat deformation; on the other hand, because the space from the air chamber cover to the bottom of the dashboard is small, it is not enough to weld the bracket, which also increases the cost and the structural strength is insufficient, which makes it easy for the dashboard to be damaged when it is impacted.
