Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of AB pillars of automobiles. Specifically, the embodiments of the present application relate to an AB pillar of an automobile, a method for preparing an AB pillar of an automobile, and an automobile. Background Art

[0002] In the automobile manufacturing industry, the AB pillars are an important part of the automobile body structure, located between the windshield and the door of the car, and play a role in supporting and protecting the body structure. Traditional AB pillars are usually made of opaque plastic or other materials, which to a certain extent limits the driver's field of vision and creates a blind spot, which may have a certain impact on driving safety.

[0003] In order to meet the market demand for innovative car appearance, car manufacturers continue to explore the application of different post-processing processes and materials themselves to the appearance of AB pillars, such as spraying, printing, coating, etc. Although these post-processing processes can bring unique colors and effects to AB pillars, they do not fundamentally solve the problem of blind spots.

[0004] In recent years, with the update of automobile design concepts and the advancement of technology, more and more automobile manufacturers have begun to consider applying transparent materials to AB pillars to expand the driver's field of vision and reduce blind spots. However, due to the influence of the internal structure of the AB pillars and the mold structure, there are many difficulties in achieving this goal. The application of pure transparent parts will not only expose the complicated and messy internal structural parts, but also the appearance defects such as gates, stress marks, BOSS pillars, etc. caused by the injection molding of the transparent parts themselves will be exposed, affecting the overall appearance of the car.

[0005] Therefore, how to maintain the structural strength and aesthetics of the AB pillars while effectively expanding the driver's field of vision and reducing blind spots has become a technical problem that needs to be urgently solved in the current automobile manufacturing industry.

[0048] Various exemplary embodiments of the present application are now described in detail. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application unless otherwise specifically stated.

[0049] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0050] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0051] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0052] The AB pillar of the automobile, the preparation method thereof, and the automobile provided in the embodiments of the present application are described in detail below in conjunction with specific embodiments.

[0053] According to one embodiment of the present application, an AB pillar of a car is provided. Figures 1 to 4 The AB pillar is located between the windshield and the door of the car, and the AB pillar includes a pillar body 1 and a grating layer 2; the pillar body 1 is mainly composed of a first part 11, a second part 12 and a third part 13, and the first part 11 is connected between the second part 12 and the third part 13; wherein at least the first part is a transparent material; the grating layer 2 is at least arranged on the surface of the first part 11, and the grating layer 2 is a line pattern composed of at least one element of a straight line, a curve and a broken line in a densely arranged manner.

[0054] The AB pillars of a car are an important part of the entire body structure. Together with the roof, floor and other parts, they form the main skeleton of the car. In the event of a collision, the AB pillars can effectively absorb and disperse the impact force, protecting the integrity of the passenger compartment and the safety of the passengers. However, since the AB pillars of a car are located in front of and to the side of the driver's line of sight, they will block part of the line of sight and form a blind spot for the driver. Traditionally, the AB pillars of a car are usually made of opaque plastic or metal materials, which further exacerbates the field of vision problem.

[0055] Nowadays, as consumers' requirements for car appearance increase, more and more designers are beginning to explore how to improve the aesthetics of the car's AB pillars while ensuring structural safety.

[0056] In an embodiment of the present application, a solution is proposed to apply a grating structure to the AB pillars of a car, thereby achieving an improvement on the AB pillars, which is described in detail below.

[0057] This application realizes the application of transparent materials on the AB pillars of automobiles. Figures 1 to 3 At least the first part 11 on the column body 1 of the AB column is replaced with a transparent material, such as transparent plastic, etc. Since the first part 11 here is located in the driver's blind spot, this can significantly reduce the AB column's obstruction of the driver's field of vision and improve driving safety.

[0058] The present application also introduces a grating layer 2, which is arranged on the surface of at least the first portion 11 (for details about the first portion 11, see Figures 1 to 4 ). Further, the grating layer 2 is a line pattern composed of at least one element of a straight line, a curve and a broken line in a dense arrangement. Based on the characteristics of the grating structure, the grating layer 2 can produce a unique light reflection effect, so that the AB pillars of the car present different visual effects at different angles. This design not only enhances the aesthetics of the AB pillars of the car, but also further reduces the blind spot of the field of vision through the refraction and reflection of light.

[0059] The AB pillar of the automobile provided in the embodiment of the present application is based on the use of transparent materials, especially the use of transparent materials on at least the first part 11 thereon, which can significantly reduce the obstruction of the driver's field of vision by the AB pillar of the automobile, thereby improving driving safety. The driver can more clearly observe the conditions around the vehicle, especially the blind spots when turning or changing lanes.

[0060] The AB pillar of the automobile provided in the embodiment of the present application has an aesthetic and decorative effect. Specifically, a grating layer 2 is designed on the column body 1 of the AB pillar. The design of the grating layer 2 is not only functional, but also enhances the appearance of the entire AB pillar. Through the dense arrangement of line patterns, a unique visual effect can be created to enhance the overall appearance and interior style of the automobile.

[0061] The line pattern of the grating layer 2 may also help reduce glare caused by direct sunlight, or guide light through a specific pattern design to further improve the light environment in the cab.

[0062] In addition, since the pattern of the grating layer 2 can be composed of a variety of elements such as straight lines, curves and broken lines, this provides great flexibility for designers and allows customized designs to be made according to different vehicle models and style requirements.

[0063] The AB pillar design of the automobile provided in the embodiment of the present application divides the pillar body 1 into three parts and splices them together, which helps to optimize the structural strength and facilitates manufacturing and installation. For example, the material selection, thickness and shape of different parts can be adjusted as needed to achieve optimal mechanical properties.

[0064] The design of the AB pillars of the automobile provided in the embodiment of the present application not only improves the driver's field of vision and driving safety, but also enhances the aesthetics and possible structural performance of the vehicle by combining transparent materials and grating layer 2 technology. This innovative design is expected to be widely used in the automobile manufacturing industry.

[0065] In summary, the AB pillars of the automobile provided in the embodiment of the present application can produce a unique light reflection effect by applying a grating structure on the AB pillars of the automobile. The grating structure can reflect different images at different angles, bringing visual enjoyment to the driver and passengers. The present application designs at least part of the AB pillars as a transparent material, and applies a grating structure on the transparent material. This can not only keep the appearance of the automobile fashionable and novel, but also effectively cover the complicated and messy internal structural parts, preventing these internal structural parts from affecting the overall appearance of the automobile.

[0066] Traditional non-transparent AB pillars are prone to form blind spots, posing a potential threat to the driver's driving safety. This application replaces part or all of the AB pillars with transparent materials and applies a grating structure, allowing the driver to see the road conditions next to the AB pillars more clearly, thereby effectively alleviating the blind spot problem and improving driving safety.

[0067] In addition, in the embodiment of the present application, the AB pillars are composed of three sections spliced ​​together, which is not only easy to install and disassemble, but also provides convenience during maintenance, reducing maintenance costs and time.

[0068] In some examples of the present application, the second portion 12 and the third portion 13 are both made of transparent materials, and the grating layer 2 is also disposed on the surfaces of the second portion 12 and the third portion 13 .

[0069] According to the AB column provided in this example of the present application, when the second part 12 and the third part 13 on the column body 1 are also made of transparent materials, then this will

[0070] The AB pillar provided in this example of the present application achieves full transparency. Specifically, the entire AB pillar, including the first part 11, the second part 12 and the third part 13, is made of transparent materials. This minimizes the obstruction of light by the AB pillar, greatly improving the light transmittance in the car and the driver's field of vision.

[0071] When the column body 1 of the entire AB column is a transparent member, the grating layer 2 should not only cover the surface of the first portion 11, but also extend to the surfaces of the second portion 12 and the third portion 13. The comprehensive grating layer coverage provides a more unified and coordinated visual effect for the AB column.

[0072] In addition, since the grating layer 2 can form a line pattern by densely arranging at least one element of straight lines, curved lines and broken lines, a rich visual effect can be created on the AB column.

[0073] Different line patterns and arrangements can produce different light refraction effects, making the AB column present a changing appearance at different angles and light.

[0074] The design of the entire transparent AB pillar greatly reduces the driver's blind spot, especially when turning and changing lanes, so that the surrounding traffic conditions can be observed more effectively. This helps to improve driving safety and driving comfort. The comprehensive coverage and diverse line patterns of the grating layer 2 add a unique visual effect to the AB pillar and enhance the overall aesthetics of the vehicle. The combination of transparent material and grating layer 2 helps to reduce glare caused by direct sunlight and improve the light comfort in the cab.

[0075] In addition, the design of the entire transparent AB pillar also facilitates the subsequent manufacturing and installation process.

[0076] The entire transparent AB pillar design in this example of the present application not only significantly improves the driver's field of vision and the aesthetics of the vehicle, but also achieves personalized visual effects and optimized light management through the diversified design of the grating layer. This design is expected to provide new inspiration and direction for the future automotive manufacturing industry.

[0077] In some examples of the present application, the second portion 12 and the third portion 13 are both made of non-transparent materials.

[0078] According to the AB pillar provided in this example of the present application, only a part of the AB pillar adopts transparent material, rather than the entire pillar. Specifically, the first part 11 on the pillar body 1 of the AB pillar is designed as a transparent area, which is located near the driver's blind spot to optimize the line of sight. At this time, the grating layer 2 can be only provided in the transparent material part to enhance the visual effect and light management.

[0079] In this example of the present application, the second portion 12 and the third portion 13 are maintained as non-transparent materials, which can ensure the structural strength, privacy protection and cost savings of the entire AB pillar.

[0080] By using transparent materials in specific areas on the column body 1 of the AB column and setting the grating layer 2, the driver's visual blind spot can be effectively reduced, helping the driver to better observe the surrounding environment. At the same time, the design of the grating layer 2 can also guide light and improve the light comfort in the cab.

[0081] Compared with the design of the entire transparent column body 1, the design of the partial transparent column body 1 can significantly reduce the material cost. At the same time, the non-transparent part can maintain the existing manufacturing process and material selection without major changes.

[0082] In addition, the non-transparent parts can be made of stronger materials to maintain the structural strength of the AB pillars, which helps ensure the safety of the vehicle in extreme situations such as collisions.

[0083] The partially transparent AB column design in this example of the present application achieves multiple technical effects such as optimizing the field of view, reducing costs, maintaining structural strength, personalized design and light management by using transparent materials and grating layers 2 only in specific areas on the column body 1. This design not only meets the safety requirements, but also improves the aesthetics and practicality.

[0084] In some examples of the present application, the grating layer 2 is formed by any of the following methods:

[0085] Forming the line pattern on the transparent plate 101 by printing;

[0086] Forming the line pattern on the transparent plate 101 by laser engraving; and

[0087] The line pattern is formed on the film 21 by printing or laser engraving, and then the film 21 is attached or injection molded on the transparent material of the column body 1;

[0088] The transparent plate 101 with the line pattern is processed into a shape matching at least the first part of the column body 1 .

[0089] In this example of the present application, the grating layer 2 is formed in a variety of ways, including but not limited to forming a line pattern on a transparent plate by printing or laser engraving, and forming a line pattern on a film by printing or laser engraving and then attaching or injection molding it to the transparent material of the column body 1. In addition, the transparent plate with the line pattern can also be processed into a shape that matches at least the first part of the column body 1.

[0090] In this example of the present application, there are multiple options for forming the grating layer 2, which provide different technical paths to achieve the grating effect, and each has a specific technical effect.

[0091] The first formation method of the grating layer 2 is described as follows:

[0092] The line pattern is formed on the transparent plate 101 by printing, which involves printing on a transparent plate 101 using high-precision transparent UV ink.

[0093] Specifically, ink can be attached to the transparent plate 101 by screen printing technology or roller printing technology to form a densely arranged line pattern. The printing method can achieve a very fine line pattern, and the line density can reach a very high level (such as ≥600 lines / mm), thereby providing an excellent grating effect. The shape of the line (straight line, curve, broken line, etc.) and the arrangement method can be adjusted according to design requirements, increasing the design flexibility of the product.

[0094] For mass production, printing is a cost-effective method.

[0095] The second method for forming the grating layer 2 is as follows:

[0096] The line pattern is formed on the transparent plate 101 by laser engraving. This method involves using a laser engraving machine to form grooves on the pre-set transparent plate 101 by burning with a light beam, thereby forming a line pattern.

[0097] Laser engraving can form grooves on the transparent plate 101. Since the grating lines are physically engraved on the transparent plate 101, this method has high durability and is not easy to wear.

[0098] The third method for forming the grating layer 2 is as follows:

[0099] A line pattern is formed on the film 21 by printing or laser engraving, and then the film is attached or injection-molded onto the transparent material of the column body 1 .

[0100] The film 21 is, for example, a PET film.

[0101] The third method is specifically: first print or laser engrave a line pattern on a film, and then attach or inject the film with the line pattern onto the transparent material of the column body 1 by intra-film injection or intra-film transfer. It can be seen that this method allows the line pattern of the grating structure to be first made on the film 21, and then applied to the appropriate position on the already processed column body 1.

[0102] The diaphragm has a thin thickness and good flexibility, and is suitable for product shapes with large curvatures. By printing or laser engraving line patterns on the diaphragm, and then attaching or injection molding it on the column body 1 by intra-film injection molding or intra-film transfer, a grating effect of a complex shape can be achieved. In other words, the diaphragm can fit tightly to the surface of the column body of various complex shapes, including curved, concave or irregular surfaces, without sacrificing the presentation of the grating effect.

[0103] For the manufactured column body 1, direct film pasting is a fast and convenient post-processing method without the need for additional processing or modification of the column body itself.

[0104] In addition, if the grating layer 2 is damaged or aged, only the diaphragm needs to be replaced without replacing the entire column body 1.

[0105] It should be noted that the transparent plate 101 can be processed adaptively according to the shape of the column body 1. The material of the transparent plate 101 includes at least one of glass, plastic and carbon fiber composite material.

[0106] The following describes in detail the method for implementing the grating layer 2 on the transparent plate 101 (such as a glass substrate or a plastic substrate) and the film 21 (such as a PET film), including three main processes: printing, laser engraving, and film printing.

[0107] Directly manufacturing the grating layer 2 on the transparent plate 101 of the present application includes two processes.

[0108] (1) Printing process (i.e., embossing method), as follows:

[0109] A glass plate (suitable for a flat structure and cannot be bent) or a transparent plastic material is selected as the material of the transparent plate 101, and there is no specific requirement for the thickness.

[0110] Use ultra-fine steel screen, nylon screen printing or high-precision roller printing plate, and ensure that the screen mesh is not less than 400 mesh to ensure printing accuracy. When roller printing, the roller accuracy needs to be adjusted according to the line requirements.

[0111] The specific process of printing is as follows:

[0112] Lay the transparent plate 101 flat and fix it under the screen (steel mesh or nylon mesh);

[0113] Fix the screen on the transparent plate 101 and apply transparent UV ink;

[0114] Use a scraper to evenly scrape the ink, and the ink leaks onto the transparent plate 101 through the pattern on the screen to form the required lines. The thickness of the line ink is controlled to be 1-20μm. Of course, if roller printing is used, the screen is replaced with a roller engraved with lines, and rolling printing is performed on the transparent plate 101;

[0115] Place the printed transparent plate 101 in a UV irradiator at 600-1000MJ / cm 2 In this way, a grating layer 2 is formed on the transparent plate 101.

[0116] (2) Laser engraving process (i.e. recessed method), as follows:

[0117] Using a laser engraving machine, fine lines are engraved on the surface of the transparent plate 101 by burning, and the lines are in various forms, including straight lines, curves, broken lines, etc. The depth of the groove formed by laser engraving is adjusted according to the effect requirements, ranging from 0.01mm to 0.1mm.

[0118] (3) When the curvature of the AB pillar of the car is large and it is not convenient to heat-bend the plate, a line pattern can be formed on a film 21 first. Specifically, a PET film with a thickness between 0.01 mm and 0.3 mm is selected, and a transparent UV grating strip is printed on the front of the PET film by screen printing or roller printing technology. Then, the printed film is attached or injection molded on the surface of the column body by film injection molding or film transfer technology, see Figure 7 .

[0119] The three processes described in this example of this application are suitable for the production of grating structures in different scenarios. Raised printing is suitable for flat or slightly curved surfaces; recessed engraving provides another visual effect, especially suitable for occasions that pursue unique texture; and film printing is flexible and applicable to various complex curved surfaces, especially when traditional plate processing is limited. Each process requires strict control of the accuracy and depth of printing or engraving to ensure the quality and aesthetics of the final grating effect.

[0120] In some examples of the present application, the transparent material includes at least one of glass, plastic, and carbon fiber composite material.

[0121] Glass materials have excellent transparency and weather resistance, providing good visual effects and durability.

[0122] Plastic materials have high plasticity and low cost, and are suitable for large-scale production and processing of various complex shapes.

[0123] Carbon fiber composite materials are not only highly transparent, but also have excellent mechanical properties and lightweight characteristics. They can enhance the structural strength and rigidity of the AB pillars of the car while reducing the overall weight.

[0124] The three materials in this example of the present application have their own characteristics and can meet the needs of different application scenarios. For example, glass is suitable for high-end models and designs that pursue high transparency; plastic is more suitable for low cost and large-scale production; and carbon fiber composite materials are more suitable for models that pursue high performance and lightweight.

[0125] Regardless of glass, plastic or carbon fiber composite material, a grating layer 2 can be formed on its surface by printing, laser engraving or the like, thereby achieving a unique light reflection effect.

[0126] The use of transparent materials combined with the grating layer 2 design allows the car's AB pillars to present rich visual effects at different angles, enhancing the sense of technology and fashion in the car.

[0127] Among them, the addition of carbon fiber composite materials not only improves the transparency of the AB pillars, but also significantly enhances their structural strength and rigidity, while achieving lightweight, which helps to improve the fuel economy and performance of the car.

[0128] As a low-cost and easy-to-process material, plastic can effectively reduce the production cost of automobile AB pillars while meeting market demand.

[0129] The diverse selection of transparent materials enables this application to meet the needs of more different car models and design styles, enhancing its market competitiveness and adaptability.

[0130] This example of the present application uses at least one of glass, plastic and carbon fiber composite materials as the transparent material, combined with the grating layer 2 design, to achieve significant improvements in the visual effects, structural performance, production costs, lightweight design and adaptability of the AB pillars of the car.

[0131] In some examples of this application, see Figure 5 and Figure 6 , the line density of the line pattern is: ≥600 lines / mm.

[0132] Line density refers to the number of lines per unit length. In this example of the present application, the line density is ≥600 lines / mm, which means that there are at least 600 lines per millimeter of length.

[0133] See also Figure 5 and Figure 6 The lines in the line pattern may be straight lines, and the straight lines may be oblique lines, and the lines in the line pattern are densely arranged.

[0134] In this example of the present application, the arrangement of lines with a higher density can produce a delicate grating effect, so that richer images and light refraction effects can be seen when viewed from different angles. This enhances the visual effect of the AB pillars of the car. In addition, the high-density lines can effectively cover the messy wiring inside the car, making it difficult to easily see the internal structural details from the outside, which is particularly important for using transparent materials as the AB pillars of the car, because it can keep the appearance of the car neat and beautiful while avoiding exposure of the internal structure.

[0135] In some examples of this application, see Figure 7 The thickness of the diaphragm 21 is T, 0.01mm≤T≤0.3mm.

[0136] Among the methods for forming the grating layer 2 of the present application, the third method involves first forming a line pattern on a film 21. The film 21 here has a relatively thin thickness and good flexibility, and is suitable for product shapes with a large curvature.

[0137] The thickness of the diaphragm 21 directly affects the difficulty of processing and the quality of the finished product. Within the thickness range of this example of the present application, the diaphragm 21 printed with dense line patterns (i.e., grating structures) can be placed on the surface of the column body 1 of the AB column using precise in-film injection molding or in-film transfer technology.

[0138] Although a thinner film can be more easily bent and fit the surface of the column body 1 of a complex shape, it also requires higher processing accuracy and more detailed printing technology to ensure the clarity and uniformity of the line effect of the grating. The thickness range of the film 21 provided in this example of the present application takes into account both the process difficulty and the fit with the column body 1 of the AB pillar of the automobile.

[0139] The film 21 within the thickness range of this example of the present application can be closely attached to the surface of the column body 1 of the AB column of the automobile, and is not prone to problems such as bubbles or warping. This allows the grating layer 2 to be evenly distributed on the surface of the column body 1, presenting a clear and delicate visual effect.

[0140] While ensuring the transparent texture of the car's appearance, the grating structure on the film 21 can effectively cover the car's internal structure and disorderly wiring. Even if the car's internal components or wiring are relatively complex, the refraction effect of the grating structure can still show a neat and beautiful appearance from the outside.

[0141] In some examples of this application, see Figure 4 A magnetic attraction component 15 is disposed on the back of the first part 11. The first part 11 is disposed on the body frame of the automobile by magnetic attraction and is located between the windshield and the door of the automobile.

[0142] The magnetic attraction member 15 may be a magnet or a metal sheet that can be attracted by magnets.

[0143] The magnetic member 15 can be provided in two pieces and disposed at both ends of the first part 11. In this way, the first part 11 can be quickly, easily and firmly connected to the body frame of the automobile, and can also be conveniently connected to the second part 12 and the third part 13 by magnetic attraction.

[0144] Magnetic installation does not require complicated fixings or screws, which reduces the difficulty and cost of installation, while improving the flexibility and detachability of installation. This not only facilitates the replacement and maintenance of components, but also reduces the labor intensity and time cost during the installation process.

[0145] The magnetic installation method makes it unnecessary to dismantle the entire AB pillar or damage the vehicle body structure when repairing or replacing the first part 11. This reduces the difficulty and cost of repair, while improving the efficiency and convenience of repair.

[0146] In the present application, the first part 11 of the column body 1 is specially designed because it is a key area of ​​the driver's field of vision on the AB column and is also a place where the traditional AB column is prone to blind spots. By installing a transparent member with a grating layer 2 at this position of the AB column, the blind spot can be effectively reduced, which enables the driver to see the road conditions and surrounding environment ahead more clearly during driving, thereby improving driving safety and comfort.

[0147] The grating layer 2 has the characteristics of the grating structure, which not only has a unique light reflection effect, but also can visually increase the layering and three-dimensional sense of the transparent part. When light passes through a transparent part with a grating structure, such as the first part 11 with the grating layer 2, different refraction and reflection effects will be produced, thereby enriching the visual experience of the driver.

[0148] In some examples of this application, see Figures 1 to 4 One end of the first part 11 is magnetically connected to the second part 12, and the other end of the first part 11 is magnetically connected to the third part 13, and the first part 11, the second part 12 and the third part 13 are spliced ​​into one.

[0149] The column body 1 of the present application is designed to be composed of three parts that are magnetically spliced ​​together.

[0150] Specifically, see Figure 3 and Figure 4 , the two ends of the first part 11 (with magnetic parts 15) are respectively connected to the magnetic part 14 at the end of the second part 12 and the magnetic part 15 at the end of the third part 13 by magnetic attraction. Magnetic splicing does not require additional fixings or adhesives, and realizes a quick, simple and stable connection between components.

[0151] In the present application, the modularization and flexibility of the design are achieved by dividing the AB pillar design of the automobile into multiple modules such as the first part 11, the second part 12 and the third part 13. This modular design allows each component to be produced, tested and replaced separately, reducing production costs and maintenance difficulties.

[0152] Due to the modular design, when a part fails or is damaged, it can be replaced individually without replacing the entire AB pillar. This reduces the cost of repair and replacement while improving repair efficiency and convenience.

[0153] The column body 1 of the present application, the first part 11 as a transparent component with a grating texture, not only has a unique light reflection effect, but also can visually increase the layering and three-dimensional sense of the entire AB column. The different refraction and reflection effects of the grating structure enrich the driver's visual experience and improve the overall aesthetics of the car.

[0154] According to one embodiment of the present application, a car is provided, comprising: a body frame and the AB pillar of the car as described above, wherein the AB pillar is arranged on the body frame and located between a windshield and a door of the car.

[0155] The AB pillars of the automobile of the present application are made of transparent materials, and a grating texture is formed on the surface through a specific printing or laser engraving process. This design enables the AB pillars to have a unique visual effect while maintaining structural strength, and can produce different light refractions according to different light angles, providing the driver with a richer visual experience.

[0156] The AB pillar of the automobile of the present application is cleverly divided into multiple modules, such as the first part 11 (transparent grating component), the second part 12 and the third part 13. These modules are connected by magnetic attraction, which not only realizes stable splicing, but also facilitates future maintenance and replacement.

[0157] Because the car's AB pillars are made of transparent materials and the internal structure is cleverly hidden, the driver's blind spot is significantly reduced. This helps improve driving safety and enables the driver to observe the surrounding environment more clearly, so as to make more accurate driving decisions.

[0158] In this application, the design of the AB pillars of the car not only focuses on practicality, but also takes full account of aesthetic factors. The addition of the transparent grating structure makes the AB pillars a highlight of the car's appearance, which can attract consumers' attention and enhance the overall aesthetics of the car.

[0159] In summary, the automobile of the embodiment of the present application not only achieves the optimization of the field of vision and the perfect combination of aesthetics and practicality by adopting the innovative AB pillar design as described above, but also improves the driving safety and market competitiveness of the automobile. This design idea and technical means are of great significance to promoting technological innovation and development of the automobile manufacturing industry.

[0160] According to one embodiment of the present application, a method for preparing an AB pillar of an automobile is provided, the method comprising the following steps S100 to S300:

[0161] Step S100, providing a transparent plate 101, and forming a grating layer 2 on the transparent plate 101 by printing or laser engraving;

[0162] Step S200, processing the transparent plate 101 with the grating layer 2 into a shape matching at least the first part; wherein the column body is mainly composed of the first part 11, the second part 12 and the third part 13;

[0163] Step S300: Connect the processed second part 12 and the third part 13 to the two ends of the first part 11 respectively to form the AB pillar of the automobile.

[0164] According to step S100 provided in the embodiment of the present application, the selection of the transparent plate 101 makes the formed AB pillar transparent, which can reduce the driver's visual blind spot and improve driving safety. The grating layer 2 is formed on the transparent plate by printing or laser engraving, which gives the formed AB pillar a unique light reflection effect. This grating structure can produce different visual effects according to different observation angles, thereby increasing the aesthetics and technological sense of the AB pillar.

[0165] The step S200 provided in the embodiment of the present application is to process the transparent plate 101 with the grating layer 2 according to the shape of the first part 11 of the column body 1 .

[0166] It should be noted here that the column body 1 includes not only the first part 11, but also the second part 12 and the third part 13. When the second part 12 and the third part 13 are also designed to combine transparent material with the grating layer 2, the transparent plate 101 with the grating layer 2 can be processed according to the shapes of the second part 12 and the third part 13.

[0167] This step is connected with the subsequent splicing step to form a complete AB column preparation process.

[0168] Step S300 of the present application: connecting the processed second part 12 and the third part 13 to the two ends of the first part 11 respectively to form the AB pillar of the automobile.

[0169] The second part 12 and the third part 13 can be made of the transparent plate 101 with the grating layer 2 made in step S100, or can be made of other plates or materials.

[0170] Finally, the first part 11, the second part 12 and the third part 13 are spliced ​​together to form the AB pillar of the automobile provided in the embodiment of the present application.

[0171] That is to say, after the preparation of the above steps S100 to S300, the AB pillar of the car with a unique grating effect is finally formed. Such AB pillar is not only aesthetically pleasing and technological, but also can reduce the driver's visual blind spot and improve driving safety.

[0172] According to one embodiment of the present application, a method for preparing an AB pillar of an automobile is provided, the method comprising the following steps S400 to S500:

[0173] Step S400, providing a film 21, and forming a grating layer 2 on the film 21 by printing or laser engraving;

[0174] Step S500, attaching or injecting the membrane 21 with the grating layer 2 onto the transparent material of the processed column body 1 by intra-film injection or intra-film transfer to form the AB pillar of the automobile; wherein the column body 1 includes a first part 11, a second part 12 and a third part 13, and at least the first part 11 is a transparent material.

[0175] The step S400 provided in the embodiment of the present application is: providing a diaphragm 21 and forming a grating layer 2 thereon. Specifically, in this step, firstly, a diaphragm 21 is prepared, and its thickness can be in the range of 0.01 mm to 0.3 mm. Then, the grating layer 2 can be formed on the diaphragm 21 by printing or laser engraving.

[0176] The printing method can be screen printing or roller printing, using high-precision transparent UV ink to form dense line patterns. The line pattern can include straight lines, curves or broken lines, and the specific shape and precision can be controlled according to design requirements.

[0177] Among them, the laser engraving method is to burn the surface of the diaphragm with a laser beam to form fine lines or grooves.

[0178] The step S500 provided in the embodiment of the present application is: attaching or injecting the diaphragm 21 with the grating layer 2 onto the processed transparent material of the column body 1. In this step, the column body 1 has been processed and formed, and includes a first part 11, a second part 12 and a third part 13. Among them, at least the first part 11 is a transparent material, and the diaphragm 21 with the grating layer 2 can be attached or injected onto the transparent material of the first part 11 by intra-film injection or intra-film transfer. In this way, the grating layer 2 will be tightly combined with the column body 1 to form an AB column with a grating effect.

[0179] It should be noted that, when the second part 12 and the third part 13 are also made of transparent materials, the film 21 with the grating layer 2 can also be attached or injected to the second part 12 and the third part 13 by intra-film injection or intra-film transfer. Of course, when the second part 12 and the third part 13 are made of non-transparent materials, this step can be omitted.

[0180] By first forming the grating layer 2 on the film 21 and attaching or injecting it on the transparent material of the AB pillar, the innovative application of the grating structure on the AB pillar of the car is realized. This design is not only beautiful and unique, but also can produce a unique light reflection effect, improving the overall visual texture of the vehicle.

[0181] Traditional AB pillars are often made of opaque materials, which easily form blind spots. In this application, by designing at least a part of the AB pillars as transparent materials and combining them with a grating structure, the driver's blind spots can be visually alleviated. At the same time, the grating structure can also reflect different light effects from different angles, further increasing the openness and transparency of the field of vision.

[0182] Although at least a portion of the AB pillars are designed to be made of transparent materials, the clutter of the built-in components may still affect the appearance. However, the grating structure in the present application can effectively cover the clutter of the built-in components, making the appearance more neat and beautiful. The clutter of the structural components cannot be seen from the appearance, and the surface can be transparent.

[0183] Compared with the traditional AB column preparation process, the method in this example is simpler and more efficient. Through the method of intra-film injection or intra-film transfer, the film with the grating layer 2 can be easily attached or injected on the transparent material of the AB column without complicated post-processing process.

[0184] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0185] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
