Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
As shown in fig. 1 to 4, the present disclosure provides a vehicle B-pillar, which may include a B-pillar outer panel 1, a B-pillar inner panel 2, and a composite material layer, wherein an etch mark 11 may be formed on an inner surface of the B-pillar outer panel 1, and the formation of the etch mark 11 may increase a surface area of the inner surface of the B-pillar outer panel 1, thereby increasing a contact area between the composite material layer and the inner surface of the B-pillar outer panel 1, and facilitating the composite material layer to be laid on the inner surface of the B-pillar outer panel 1. The composite material layer can be formed into a B-column reinforcing plate 3 through a hot pressing process, the B-column inner plate 2 and the B-column outer plate 1 are welded, in an optional embodiment, the B-column inner plate 2 and the B-column outer plate 1 are made of high-strength steel, the weight of the B column can be reduced on the basis of meeting the performance requirement of the B column, and further, the yield strength of the high-strength steel can be 600-3000 MPa. The B-pillar reinforcement plate 3 is positioned between the B-pillar inner plate 2 and the B-pillar outer plate 1. The B-pillar reinforcing plate 3 is made of a composite material layer, so that the weight of a B-pillar of a vehicle can be effectively reduced, the deformation of a reinforcing area can be effectively reduced, better safety guarantee is provided for a passenger compartment, and meanwhile certain cost can be reduced.
In an alternative embodiment, as shown in fig. 1 and 2, the etching 11 may be formed by a laser etching process, and the width of the etching 11 may be 0.01-10mm and the depth may be 0.01-0.5 mm. Specifically, the inside of the etching mark 11 may be formed with a tiny sponge-like etching pattern, and when the B-pillar reinforcement plate 3 and the B-pillar outer panel 1 are pressed together, the contact area between the B-pillar reinforcement plate 3 and the inner surface of the B-pillar outer panel 1 may be effectively increased, so that the connection is more secure.
In an optional implementation mode, the composite material layer can be one or more of a carbon fiber reinforced composite material, a glass fiber reinforced composite material, a basalt reinforced composite material, an aramid fiber reinforced composite material and an ultra-high molecular weight polyethylene fiber reinforced composite material, and is made in a prepreg form, so that the weight of the vehicle is reduced, and meanwhile, the cost is saved.
Specifically, as shown in fig. 1 and 4, the vehicle B-pillar further includes a glue layer 4, the glue layer 4 and a composite material layer are sequentially laid on the inner surface of the B-pillar outer panel 1, the glue layer 4 may be an epoxy resin system or a polyurethane resin system, and may be in conformity with the resin system of the B-pillar reinforcement panel 3 to enhance the coupling effect. The adhesive layer 4 can improve the sealing performance between structures and play a certain role in preventing electrochemical corrosion, and in addition, the B-pillar reinforcing plate 3 can be bonded on the inner surface of the B-pillar outer plate 1, and when bonding is carried out, the adhesive layer 4 can be fused into the etching mark 11, so that the connecting strength is effectively increased. The thickness of the glue layer 4 can be between 0 and 5mm, when the fiber volume content in the B-pillar reinforcement plate 3 which is a composite material is lower than 50%, the thickness of the glue layer 4 can be 0, that is, the glue layer 4 is not necessary to be additionally used, and when the fiber volume content is higher than 50%, the thickness of the glue layer 4 can not be 0.
In addition, as shown in fig. 1, 3 and 4, the rivet 101 for connecting the B-pillar reinforcement plate 3 and the B-pillar outer panel 1 may be a semi-hollow rivet and connected by high-speed riveting, so as to connect the B-pillar reinforcement plate 3 made of composite material and the B-pillar outer panel 1 made of metal material more firmly, thereby further reducing the risk of structural separation during collision. Because the composite material is a brittle material, the traditional self-piercing riveting mode of the semi-hollow rivet can cause the composite material to have cracks and seriously reduce the material performance, so the self-piercing riveting method cannot be effectively applied to a mixed structure of the composite material and a metal material; although the rivet pulling mode can be used, the hole needs to be punched in advance, the production efficiency is low, meanwhile, the hole needs to be punched in advance for the design of a through hole, and the problems of poor sealing performance, easy corrosion, poor fatigue resistance and the like exist. And by adopting a high-speed riveting mode, the semi-hollow rivet can quickly penetrate through the composite material without generating cracks (the instantaneous speed of high-speed riveting can be more than 350m/s) in a high-frequency vibration mode, and the existing problems can be effectively solved.
The present disclosure also provides a vehicle comprising the vehicle B-pillar described above.
The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
It should be noted that, in the foregoing embodiments, various features described in the above embodiments may be combined in any suitable manner, and in order to avoid unnecessary repetition, various combinations that are possible in the present disclosure are not described again.
In addition, any combination of various embodiments of the present disclosure may be made, and the same should be considered as the disclosure of the present disclosure, as long as it does not depart from the spirit of the present disclosure.
