Background
In the prior art, corresponding to an EV or PHEV vehicle type, as shown in FIGS. 1-2, a U-shaped reinforcing part 2 is welded with a middle channel 1 at a corresponding position of a cross beam at the lower part of the middle channel 1 in order to ensure pole collision force transmission continuity, the space is limited, and the middle channel 1 cannot be wired. The center tunnel 1 performs wiring harness arrangement from the left and right sill beam sides, resulting in a reduction in battery size and a reduction in electric power. As shown in fig. 3, the high-voltage harness or pipe 3 is arranged from both sides of the threshold, and the high-voltage harness or pipe is easily broken during a pole collision process and contacts with the battery, so that a fire risk is caused.
SUMMERY OF THE UTILITY MODEL
To solve the above technical problems in the prior art, an object of the present invention is to provide a front floor assembly structure.
The front floor assembly structure comprises a front floor, wherein a middle channel is arranged in the middle of the front floor, and a front row seat front cross beam and a front row seat rear cross beam are arranged on the front floor; the method is characterized in that: a flat plate type reinforcing piece is arranged at the position, corresponding to the front row seat front cross beam and the front row seat rear cross beam, of the bottom of the middle channel, and two sides of the flat plate type reinforcing piece are fixedly connected with two sides of the bottom of the middle channel through a plurality of bolts; the high-voltage wire harness is mounted on the flat plate type reinforcement and arranged along the length direction of the center channel.
Wherein, a plurality of reinforcing ribs arranged in the Y direction are arranged on the flat plate type reinforcing piece.
Wherein the height of the reinforcing rib is more than or equal to 8 mm.
The front-row seat rear cross beam is of a split structure, and the front-row seat rear cross beam is welded and fixed with two sides of the middle channel.
Wherein, the front row seat rear cross beam is of an integral structure.
Compared with the prior art, the front floor assembly structure has the following beneficial effects:
the front floor assembly structure is beneficial to increasing the space for arranging the battery cell of the battery pack and ensuring the gap between the installation space of the high-voltage wire harness and the battery pack, and the flat plate type reinforcing piece can also play a role in protecting the wire harness, so that the high-voltage wire harness is prevented from falling off and contacting the battery pack, and the risk is avoided.
