detailed description

The specific implementation of the present utility model will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

As shown in Figures 1 to 7, the threshold beam of the electric vehicle includes a threshold beam body 2, and the two ends of the threshold beam body are respectively connected with the A-pillar lower structure 1 and the B-pillar 3, wherein the threshold beam body 2, the A-pillar lower structure 1. The B-pillar 3 is a hollow aluminum profile structure with small weight and high structural strength, which is conducive to the lightweight of electric vehicles and can effectively extend the cruising range of electric vehicles.

A battery fixing structure for fixing the battery is provided inside the sill beam body 2 . The battery fixing structure is arranged inside the sill beam body, compared with the traditional one, it is arranged outside the sill beam body, the structure is stable and reliable, and the space under the sill beam is saved.

The sill beam body 2 is provided with reinforcing ribs for dividing the interior of the sill beam body into a group of cavities. The reinforcing rib and the sill beam body are integrally structured, and the reinforcing rib is a plate-like structure. The battery fixing structure is arranged in the lowermost cavity of the sill beam body, that is, installed on the bottom plate of the sill beam.

The upper part of the threshold beam body 2 is provided with a hollow protrusion, and the protrusion is integrated with the threshold beam body. Both ends of the sill beam body are provided with sealing plates, the sealing plates are respectively a front sealing plate 207 and a rear sealing plate 206, both of which are aluminum plates and are light in weight.
