Embodiment 1

[0071] Such as Figure 1 to Figure 6 As shown, the front floor structure provided by Embodiment 1 of the present disclosure includes a connecting plate 1, a sealing cover, a front seat-mounted front beam 3 and a front seat-mounted rear beam 4, and the sealing cover is used to seal the battery pack of the battery pack 2. Cover 201, the connecting plate 1 is provided with a gap, the battery pack 2 is set at the position of the gap, the top edge of the battery pack sealing cover 201 is connected to the inner side of the connecting plate 1 and covers the gap, to form the front floor.

[0072] The battery pack sealing cover 201, the front seat installation front beam 3 and the front seat installation rear beam 4 are composite material parts, and the front seat installation front beam 3 and the front seat installation rear beam 4 are integrally formed on the On the battery pack sealing cover 201, the front seat installation front beam 3 and the front seat installation rear beam 4 e...

Embodiment 2

[0106] Such as Figure 7 Shown is the front floor structure provided by Embodiment 2 of the present disclosure. The difference from Embodiment 1 is that because some luxury cars have higher requirements on body performance, the front seat is equipped with a front beam 3 and the front seat is equipped with a rear beam 4. Special high-strength composite materials (for example: carbon fiber) should be selected for molding. At this time, the front seat-mounted front beam 3 and the front seat-mounted rear beam 4 are fixedly connected to the battery pack sealing cover 201 by means of gluing and riveting.

Embodiment 3

[0108] Such as Figure 8 to Figure 14 Shown is the front floor structure provided by Embodiment 3 of the present disclosure. In the following embodiment, the same parts as the first embodiment will not be described again.

[0109] In one embodiment, as Figure 8 to Figure 13 As shown, the battery pack installation frame 5 includes a battery pack left installation beam 501, a battery pack right installation beam 502, a battery pack front installation beam 503, a battery pack rear installation beam 504 and a battery pack middle installation beam.

[0110] The front mounting beam 503 of the battery pack, the right mounting beam 502 of the battery pack, the rear mounting beam 504 of the battery pack, and the left mounting beam 501 of the battery pack are sequentially connected to form a rectangular frame b, and the middle mounting beam of the battery pack is connected to Inside the rectangular frame, a plurality of closed-loop beam structures are formed between the battery pack ...

Abstract

The disclosure belongs to the technical field of automobile front floor, and relates to a front floor structure and an automobile. The front floor structure includes a connecting plate, a sealing cover, a front crossbeam installed on the front seat and a rear crossbeam installed on the front seat, the sealing cover is a battery pack sealing cover of a battery pack, a gap is arranged on the connecting plate, and the battery The battery pack is arranged at the position of the gap, and the top edge of the battery pack sealing cover is connected to the inner side of the connecting plate and covers the gap to form a front floor; the battery pack sealing cover, the front seat are installed on the front beam and The rear crossbeam installed on the front seat is a composite material, and the front crossbeam installed on the front seat and the rear crossbeam installed on the front seat are fixedly connected or integrally formed on the sealing cover of the battery pack. The front floor structure can improve space utilization and increase the minimum ground clearance of new energy vehicles.

Description

technical field [0001] The disclosure belongs to the technical field of automobile front floors, and in particular relates to a front floor structure and an automobile. Background technique [0002] The existing automobile front floor, as an important part of the sealing of the passenger compartment, is usually a sheet metal panel structure, which is welded with the floor frame on the welding line to form an assembly. Most of the existing front seat beams are sheet metal beam parts, the two ends of the seat beam are sheet metal stamping joints, the joints are welded with the seat beam to form a seat beam assembly, and then welded with the front floor to form a front floor structure. [0003] However, the front floor and the front seat mounting crossbeam require multiple sets of stamping dies, the cost is high, and there are many welding sequences, many welding fixtures are required, the welding accuracy is difficult to guarantee, and the production efficiency is low. In add...
