Description

Technical Field

[0001] The present application relates to the technical field of vehicle A-pillars, and in particular to a vehicle A-pillar structure, a transparent part molding method and a vehicle. Background Art

[0002] The A-pillar of a vehicle refers to the pillar between the front windshield and the left and right front doors. It is one of the key components that bears the weight of the roof and ensures collision safety. In order to ensure the structural strength and safety performance of the A-pillar of a vehicle, it is generally made of metal, such as high-strength steel plates, and is designed to be wider, but at the same time it blocks the driver's field of vision, resulting in an "A-pillar blind spot". Therefore, it is necessary to design the A-pillar of a vehicle to be transparent.

[0003] In the related technology, a hollow design is made on the existing vehicle A-pillar, or a display screen is installed on the inside of the vehicle A-pillar, and a camera outside the vehicle and a software algorithm are used to display the field of view blocked by the A-pillar.

[0004] However, hollowing out the A-pillar of a vehicle will weaken its overall structural strength; using a display screen will produce reflections during nighttime driving, affecting the driver's normal driving, and the entire system is expensive, limiting its large-scale application. It can be seen that the transparent A-pillar structure of a vehicle provided in the relevant technology cannot take into account both the load-bearing capacity and the field of view at the same time, and has the problem of low safety performance. Summary of the invention

[0005] Based on this, it is necessary to provide a vehicle A-pillar structure with high safety performance, a transparent part molding method and a vehicle in order to address the problem of low safety performance of the vehicle transparent A-pillar structure provided in the related art.

In addition, the first transparent portion 41 and the second transparent portion 51 can be assembled by adhesive bonding, which can effectively reduce the complexity of assembly on the basis of ensuring connection reliability, and also facilitate subsequent maintenance.

[0061] Referring to FIGS. 1 to 5 , a vehicle A-pillar structure provided in an embodiment of the present application includes:

[0062] substrate1;

[0063] The transparent member 2 is embedded in the substrate 1. The transparent member 2 is a fiber-reinforced composite material obtained by three-dimensional weaving. The fiber-reinforced composite material is obtained by composite processing of continuous glass fiber and thermosetting resin. The transparent member 2 is a tube beam structure with a closed cross section.

[0064] The connecting member 3 has a first end connected to the transparent member 2, and a second end connected to the substrate 1. There are two connecting members 3, which are respectively arranged at the two ends of the transparent member 2. The connecting member 3 includes: a first connecting portion 31 connected to the transparent member 2, and the cross section of the first connecting portion 31 matches the cross section of the transparent member 2; a second connecting portion 32 connected to the substrate 1;

The transparent portion is arranged corresponding to the transparent member 2, and the material of the first transparent portion 41 is plastic, composite material, glass or ceramic whose transparency meets the preset conditions;

[0067] In the vehicle A-pillar structure provided in this embodiment, the first transparent portion 41, the transparent member 2, and the second transparent portion 51 form a light path, so that the driver in the vehicle can smoothly observe the outside of the vehicle, thereby expanding the driver's field of vision and improving the safety performance of the vehicle A-pillar structure; the first transparent portion 41 and the second transparent portion 51 can be assembled by adhesive bonding, and the connecting member 3 stably and reliably connects the transparent member 2 to the substrate 1 by adhesive and bolts, which can effectively reduce the assembly complexity of each component on the basis of ensuring the reliability of the connection, and is also convenient for subsequent maintenance; the transparent member 2 is a fiber-reinforced composite material obtained by three-dimensional weaving, and has higher strength in the thickness direction. The substrate 1 and the transparent member 2 jointly provide strength and bearing capacity for the vehicle A-pillar structure, which can improve the safety performance of the vehicle A-pillar structure.

[0068] As shown in FIG6 , an embodiment of the present application provides a transparent member molding method for preparing the transparent member 2 in the above embodiment, and the transparent member molding method includes the following steps 602 to 606. Among them:

[0069] Step 602, performing three-dimensional weaving processing on the fiber to obtain a tubular fiber.

[0070] Optionally, the fibers comprise continuous glass fibers.

[0071] In this step, the fibers are subjected to three-dimensional weaving processing so that the fibers are interwoven to form a three-dimensional spatial network structure. Compared with traditional composite material laying technology, the tubular fibers obtained by three-dimensional weaving processing have greater mechanical strength in the thickness direction, and the load-bearing requirements of the vehicle's A-pillar structure can be met by thickness control.

[0072] Step 604, adjusting the solidified refractive index of the matrix material until it matches the refractive index of the fiber to obtain an intermediate material.

[0073] The matrix material may be a thermosetting resin, such as epoxy resin, unsaturated polyester resin or a mixture of multiple resins. The matching of the cured refractive index of the matrix material and the refractive index of the fiber means that the difference between the refractive indices of the two is adjusted to -0.005~+0.005.

[0074] In a possible implementation, the refractive index of the fiber can be matched by selecting matrix materials with different cured refractive indices, or by mixing multiple matrix materials. Optionally, by introducing monomers, fillers or modifiers with high or low refractive indices to match the cured refractive index with the refractive index of the fiber, the added material can be an organic or inorganic material with specific optical properties, such as barium titanate, silicate or organosilicon compound. Optionally, by adjusting the curing temperature, curing time or curing pressure, the cured refractive index of the matrix material can be precisely adjusted.

[0075] Step 606 , using the intermediate material to perform an impregnation and curing treatment on the tubular fiber to obtain a transparent member 2 .

[0076] The infiltration and curing treatment of the tubular fiber refers to infiltrating the liquid intermediate material into the tubular fiber obtained by the three-dimensional weaving treatment, and curing and forming it into the transparent part 2.

[0077] In one possible implementation, the infiltration and curing process may be performed by using vacuum assisted resin transfer molding (VARTM) technology to infiltrate the intermediate material into the tubular fiber in a vacuum environment. Vacuum assistance can ensure that the intermediate material evenly infiltrates the tubular fiber, avoids the formation of bubbles and dry spots, and improves the overall performance of the transparent part 2.

[0078] In a possible implementation, the transparent member forming method provided includes: adjusting the cured refractive index of the matrix material until it matches the refractive index of the fiber to obtain an intermediate material; performing an online continuous fiber three-dimensional weaving process on the fiber to obtain a tubular three-dimensional fiber braided body, and while weaving the tubular three-dimensional fiber braided body, infiltrating the intermediate material into the tubular three-dimensional fiber braided body, and curing and forming the transparent member 2. Optionally, the fiber is a continuous glass fiber, and the matrix material is a thermosetting resin.

[0079] The matching of the cured refractive index of the matrix material and the refractive index of the fiber means that the difference between the refractive indices of the two is adjusted to -0.005~+0.005.

[0080] In a possible implementation manner, the transparent member 2 is a tubular beam structure with a closed cross-section.

[0081] In an exemplary embodiment, a vehicle is provided, comprising the vehicle A-pillar structure as described in the above embodiment.
