Problems solved by technology

[0003] Traditional automobile sill beams, floors and seat beams are mostly made of high-strength steel plates. By optimizing the structure, material grade, and steel plate thickness, the requirements for side crashworthiness are met, but the weight of the vehicle body will be increased and the performance improvement will be limited.

Embodiment Construction

[0024] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0025] as attached figure 1 As shown, the present invention is a combined carbon fiber vehicle body sill and floor structure, which includes a sill beam 1, a front seat crossbeam 2, and a floor 3 in combination. The door sill beams, front seat cross members and floor are made of carbon fiber reinforced composite. The sill beam and the floor are connected by gluing on the inner panel of the sill beam, and pre-embedded bolts are arranged in the gluing area, which enhances the connection strength between the sill beam and the floor. The front row seat crossbeam is connected with the floor by gluing in the flange area of ​​the front row seat crossbeam.

[0026] as attached figure 2 - attached image 3 As shown, the threshold beam is composed of the thre...

Abstract

The invention discloses a combined carbon fiber vehicle threshold and floor structure. The structure comprises a threshold beam, a front-row seat horizontal beam and a floor, the threshold beam, the front-row seat horizontal beam and the the floor are composed of carbon-fiber reinforced composite materials, and the threshold beam is connected with the floor through a plate adhesive in the threshold beam; an embedded bolt is arranged in an adhesive area, and the front-row seat horizontal beam and the floor are connected through an adhesive of an edge turning area of the front-row seat horizontal beam. According to the structure, the collision resistance of the side face of an automobile is improved, the weight of the whole automobile is lowered, and the combined carbon fiber vehicle threshold and floor structure is provided.

Description

technical field [0001] The invention relates to the fields of automobile manufacturing and collision safety, in particular to a combined carbon fiber body threshold and floor structure. Background technique [0002] Body sills and floors are very important car protection components, which can effectively resist external intrusion in car side collisions, protect the integrity of the passenger compartment, and reduce the injuries of occupants in the car. Limited by the width and space of the car, the driver and passenger seats in the car are fixed on the floor crossbeam, which is very close to the side collision area. The seat beam structure can provide sufficient support for the threshold, push the cockpit away from the collision zone as soon as possible, and reduce the amount and speed of intrusion of the side wall structure into the passenger compartment. Therefore, optimizing the strength and stiffness of the body sill and the floor structure, increasing energy absorption...
