Embodiment Construction
[0033] Such as figure 1 An exemplary longitudinally extending portion 70 of the biomimetic body frame of the present invention is shown, having an integrally formed dense outer layer 71 and a porous inner layer 72 . The outer layer 71 is formed on the surface of the bionic body frame, and the inner layer 72 is formed in the inner space surrounded by the outer layer 71 and fills up the inner space. In this way, if figure 1 As shown, in a cross section transverse to the direction of longitudinal extension of the part 70 , it exhibits a bone-like density distribution. although figure 1 Only one exemplary part of the bionic body frame is shown, but it can be understood that for each part of the whole bionic body frame, especially the cross-section of each longitudinal extension part thereof can be presented as figure 1 The density distribution of the humanoid bone is shown. The bionic body frame can simplify the product development process and shorten the production cycle, and...

Abstract
The invention provides a bionic body frame and a manufacturing system and method of the bionic body frame. The bionic body frame comprises a dense outer layer and a porous inner layer which are integrally formed, and therefore, the cross section of each longitudinal extending part of the bionic body frame appears like the human bone density distribution. The manufacturing system of the bionic body frame comprises a foam melt generator, a die-casting die, a cooling system and a pressure system, wherein the foam melt generator is used for processing a base material into a foamed melt; a casting cavity of which the shape is matched with that of the bionic body frame is formed in the die-casting die, and the melt is received and contained through the casting cavity; the cooling system is used for cooling the die-casting die after the casting cavity is full of the melt; the pressure system is used for applying a pressure to the die-casting die from the outer side in order to apply a pressure to the melt in the casting cavity through the die-casting die. The bionic body frame has the effects that the weight is light, the intensity is high, the energy absorbing performance is improved, the noise is removed, and the vibration absorbed; the manufacturing system and method of the bionic body frame have the advantages that the product development process can be simplified, and the production cycle can be reduced.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a bionic body frame and a system and method for manufacturing the bionic body frame. Background technique [0002] The body is an important part of the car, and the weight of the body accounts for about 25% of the weight of the vehicle. The weight reduction of the body can lead to a series of related effects such as the lightweight of the chassis, the lightweight of the power system, and the miniaturization of the engine. [0003] In order to reduce the weight of the car body, body structure optimization technology has been widely used, the proportion of high-strength / ultra-high-strength steel plates has been greatly increased, and advanced technologies such as steel-aluminum hybrid body, all-aluminum body, and carbon fiber body have been developed and applied. [0004] However, the existing car body structural parts are often connected by extruded profiles, the production cycle is lo...
