Detailed Description

The following description of the embodiments of the present utility model refers to the accompanying drawings, which illustrate in further detail.

As shown in fig. 1 to 4, the whole power battery car integrated structure comprises a battery tray 2, a car body wheel cover guard plate 1 and a car body bottom plate, wherein the battery tray and the car body wheel cover guard plate are of an integral structure subjected to die casting, the car body bottom plate is arranged above the battery tray of the integral structure, and the battery tray and the car body bottom plate are matched to form a battery cavity structure for placing battery cells.

The vehicle body bottom plate is fixedly connected with the battery tray through a group of bolts; a sealing ring 3 is arranged between the edge of the battery tray and the vehicle body bottom plate; preferably, the sealing ring is a ring of sealing foam structure.

According to the utility model, through the integrated die-cast power battery tray structure, the integration of the new energy battery and the vehicle body bottom plate is realized, the number of parts of the whole vehicle is greatly reduced, the integration level is improved, the light weight is realized, and meanwhile, the traditional battery pack structure is truly canceled.

The front edge and the rear edge of the battery tray 2 are respectively provided with a step structure matched with the end part of the vehicle body bottom plate, and the end part of the vehicle body bottom plate is installed and positioned through the step structure, so that the connection is stable and reliable.

A convex structure for dividing the interior of the battery tray 2 into a group of areas is arranged in the battery tray; further, the protruding structure is a crisscross protruding rib structure, the protruding structure and the battery tray are of an integrated structure, and the battery cell is positioned stably and reliably.

In the utility model, the battery tray and the guard plate structure of the wheel cover of the vehicle body are manufactured by adopting an integral die-casting molding process, and the battery module is arranged in the battery tray as the traditional battery pack; the automobile body floor passes through bolt-up with battery tray, is equipped with sealed foam between tray and the automobile body bottom plate, realizes the effective seal of battery tray.
