The automobile seat backrest framework structure is used as a main body structure of an automobile seat, and the requirement on rigidity and strength needs to be met so as to bear the load of passengers and the load condition under the automobile limit working condition and protect the safety of the passengers. The traditional automobile seat backrest framework structure is a metal framework or a combination of the framework and a panel, but metal parts cannot realize the framework or a panel integrated structure due to process limitation and only can be formed by assembling and welding steel or aluminum pultruded parts and stamping parts. The defects of large overall structure weight, more assembled parts, complex assembling process, poor load bearing capacity of the tailor welded part and the like exist.

With the increasing demand for lightweight automobiles, fiber composite materials are increasingly used in the manufacture of automobile parts. To apply the fiber composite material to the automobile seat backrest framework structure, the automobile seat backrest framework structure needs to be designed according to different preparation processes of the material so as to meet the requirements of rigidity and light weight.

Detailed Description

The technical solution is further explained with reference to the drawings and the embodiments.

Example 1

As shown in fig. 1, an automobile composite material seat back skeleton structure is a structure formed by integrally molding a panel 1 of a continuous fiber reinforced resin-based composite material (including but not limited to a commercially available carbon fiber reinforced epoxy resin-based composite material and a commercially available glass fiber reinforced epoxy resin-based composite material) and a reinforcing rib 2 of a discontinuous fiber reinforced thermoplastic or thermosetting resin-based composite material (including but not limited to a commercially available carbon fiber reinforced epoxy resin-based composite material and a commercially available glass fiber reinforced epoxy resin-based composite material with a length ranging from 1mm to 200 mm) through die pressing or injection molding or a mixing process thereof. Compared with metal parts, the continuous and discontinuous fiber composite materials have smaller mass and higher specific rigidity and specific strength, and can meet the requirements of light weight and rigidity strength; and an integrated structure can be formed by die pressing or injection molding or a mixed process thereof, thereby avoiding tailor welding, simplifying the assembly process and improving the product precision.

The panel 1 is an integrated curved thin plate, is 1-5 mm thick and bears main load. The section of the reinforcing rib 2 is of an I-shaped structure (shown in figure 2), the height is 0-60 mm, the width is 1-5 mm, the bottom of the reinforcing rib is integrally connected with the panel 1, the upper part of the reinforcing rib is a flaky bulge, and the angle formed by the central line and the panel 1 is 0-90 degrees.

The number and the distribution of the reinforcing ribs 2 can be optimized according to the topology of the load condition on the basis of a finite element model. In this embodiment, the panel 1 is composed of a head area panel 11, a shoulder area panel 12, a hand area panel 13, and a back area panel 14, which are separated into areas by a head shoulder boundary stiffener 21, a shoulder back boundary stiffener 24, and a hand boundary stiffener 25, wherein the head area panel 11, the shoulder area panel 12, and the hand area panel 13 are recessed to different degrees with respect to the back area panel 14. The reinforcing ribs 2 are distributed symmetrically left and right relative to the panel 1. The head region is connected to the shoulder region by a head shoulder gusset 22. The shoulder area is distributed with transverse and longitudinal crossed shoulder reticular reinforced ribs 23 for strengthening leaning rigidity, and is connected with the hand area through the transverse reinforced ribs and connected with the back area through the longitudinal reinforced ribs. Hand transverse reinforcing ribs 26 are distributed in the hand area. The back area is distributed with a plurality of back triangular reinforcing ribs 27 which are connected with each other and used for enhancing the torsional rigidity of the backrest framework structure, and the left and the right of the back triangular reinforcing ribs 27 are respectively distributed with 4 back triangular reinforcing ribs in the embodiment and connected with the hand area through transverse reinforcing ribs.
