Technical Field

[0001] The present invention relates to the technical field of vehicle parts, and in particular to a panel and a manufacturing method thereof, and a vehicle. Background Art

[0002] In recent years, the lightweight and high-performance of automobiles have gradually become an important way to achieve the goal of energy conservation and emission reduction. Carbon fiber reinforced resin-based composite materials can reduce the weight of the vehicle while ensuring strength and safety, thereby achieving the purpose of improving endurance, reducing fuel consumption and carbon emissions. At the same time, the unique texture appearance of carbon fiber can give it a unique high-end and luxurious temperament when used as automotive interior and exterior parts.

[0003] During the implementation of the insert injection molding process, if the insert is not completely in contact with the contoured surface of the mold cavity, a slight lift of the edge will cause the injection glue to overflow to the appearance surface, making the product scrapped. Especially when using a thin-walled (thickness <1mm) carbon fiber composite material surface as an insert and injection molding large-size parts (>800mm×300mm), it is extremely difficult to achieve complete contact with the contoured surface due to its strong rigidity, large width and accompanying resin cooling and shrinkage deformation. There is a high risk of injection glue overflow and a high sample scrap rate. Summary of the invention

[0012] In one embodiment, placing the membrane with the adhesive member in a mold includes: spraying a release agent in the inner cavity of the mold; placing the membrane with the adhesive member in the mold; pressing the adhesive member with a second preset pressure to establish a second adhesive force between the adhesive member and the mold.

[0013] In one embodiment, the second preset pressure is 10N / cm 2 ~15N / cm 2 ; The second bonding force is 0.1N / cm~0.5N / cm.

[0014] In one embodiment, the connecting member is injection molded in the mold, and the connecting member is connected to the diaphragm to obtain the plate, including: injecting a precursor material of the connecting member into the inner cavity of the mold; after the precursor material is molded, the connecting member is connected to the diaphragm to obtain the plate, and the plate is connected to the adhesive member; and removing the adhesive member from the plate.

[0015] In one embodiment, after the membrane with the adhesive member is placed in the mold, the membrane with the adhesive member separates the inner cavity of the mold to form a first cavity and a second cavity, and the connecting member is injection molded in the second cavity.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0025] Unless otherwise defined, all technical and scientific terms used in the present invention have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in the present invention includes any and all combinations of one or more of the related listed items.

[0026] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] For ease of understanding, relevant technical terms involved in the present invention are explained and described below.

[0028] Insert molding: A molding method in which the insert is pre-fixed in the injection mold and the resin is injected to connect with the insert.

[0029] Prepreg: A sheet or strip of material that has been impregnated with resin and fiber and then cooled and shaped.

[0030] The present invention provides a panel and a vehicle equipped with the panel. The vehicle may be a fuel vehicle or a new energy vehicle, the panel is installed in the cabin of the vehicle, and the panel may be a decorative part in the cabin, which can enhance the appearance and protect the parts.

[0031] In one embodiment, the panel can be installed on a vehicle door, a center console, a center armrest, a steering wheel, etc.

[0032] In one embodiment, the panel may be a three-dimensional structure, and the specific shape is not limited, and the shape of the panel may be determined according to the required installation.

[0033] In one embodiment, the panel comprises a membrane and a connector connected to the membrane. Specifically, along the outermost surface of the panel (the surface that can be touched by the passenger) inward, there are the membrane and the connector in sequence.

[0034] In one embodiment, the present invention also provides a method for manufacturing a plate, please refer to Figure 1 , including the following steps:

[0035] S10, bonding an adhesive member to the film.

[0036] S20, placing the membrane in the mold and bonding the adhesive member to the mold.

[0037] S30, injection molding a connecting piece in a mold, and connecting the connecting piece to the diaphragm.

[0038] In one embodiment, in step S10, the membrane may be in a two-dimensional shape or a three-dimensional shape, and continuous or discontinuous adhesive members may be provided around the periphery of the membrane.

[0039] In one embodiment, in step S10, the diaphragm is formed of carbon fiber reinforced transparent resin prepreg, the base material of the diaphragm has high light transmittance, the diaphragm may have a preset texture state, and the pattern of the panel that the passenger can directly see comes from the diaphragm; the connecting piece is used to assemble the panel with the inner frame of the vehicle, and the connecting piece can be detachably connected to the inner frame of the vehicle.

[0040] In one embodiment, in step S10, the four edges of the diaphragm are the outer contour of the diaphragm, which can be a regular shape or an irregular shape. The adhesive member is connected end to end in a ring shape, that is, it surrounds the outer periphery of the diaphragm. By setting the adhesive member to be a ring connected end to end, the gap between the diaphragm and the inner wall of the mold can be reduced, thereby preventing the precursor of the connecting member from flowing into the back of the diaphragm through the gap.

[0041] In one implementation, in step S10, the adhesive member may also be bonded to the four edges of the membrane, and there are multiple adhesive members, specifically distributed at positions where the membrane is prone to warping.

[0042] In one implementation, in step S10, the adhesive member may be double-sided adhesive, liquid adhesive, solid adhesive, or the like.

[0043] In one implementation, in step S20, please refer to Figure 2 The mold may include a fixed mold 2 and a movable mold 5, wherein the fixed mold 2 and the movable mold 5 jointly enclose an inner cavity 3 of the mold, and a diaphragm 4 may be placed in the fixed mold 2, and a shape of the diaphragm 4 is the same as a shape of the inner cavity 3 of the fixed mold 2, so that the adhesive member 1 may be connected to the inner wall of the fixed mold 2.

[0044] In one embodiment, in step S30, the material of the connecting piece may be glass fiber reinforced polypropylene PP, polyamide PA, polyphenylene sulfide PPS, and an alloy of polycarbonate PC and acrylonitrile-butadiene-styrene copolymer ABS (PC / ABS).

[0045] In one embodiment, in step S30, the material of the connector is injection molded, and then after the connector is cooled and formed, the connector is connected to the diaphragm.

[0046] In one embodiment, before step S10, the process further includes: blanking the membrane to obtain a two-dimensional unfolded plane of the product. The two-dimensional unfolded shape of the product can be understood as: a two-dimensional sheet mold obtained after the final three-dimensional structure plate is unfolded into a plane. It can be understood that the external surface area of ​​the two-dimensional unfolded shape is the same as the external specific surface area of ​​the final three-dimensional structure plate.

[0047] In one embodiment, the two-dimensional unfolding plane is unfolded by the product digital model in the software, and then the diaphragm is placed in the middle of the punching die and the convex and concave dies to punch the blank and punch the positioning holes at the same time. The die punching machine has a tonnage of 80T and the tool material is high-speed steel.

[0048] In one embodiment, the diaphragm has a carbon fiber texture, including one or more of a continuous plain weave, a twill weave, a satin weave, or a chopped carbon fiber texture.

[0049] In one embodiment, the membrane comprises a substrate, and the material of the substrate comprises one or more of polymethyl methacrylate, polystyrene, and polycarbonate. The membrane 4 has a thickness of 1 mm±0.02 mm.

[0050] In one embodiment, before step S10, the method further includes: hot pressing and shaping the two-dimensional membrane to prepare a three-dimensional membrane. The specific steps are: laying the two-dimensional membrane on a hot pressing mold for the membrane, heating the mold to 15°C to 20°C higher than the melting point of the prepreg matrix resin, closing the mold for hot pressing, and controlling the mold clearance to be 1mm±0.02mm.

[0051] The present invention pre-bonds an adhesive component on the diaphragm, and then places the decorative film bonded with the adhesive component into the mold, so that the diaphragm and the inner wall of the mold can be connected, thereby avoiding the phenomenon that the diaphragm is warped and does not fit the mold, thereby preventing the injection molding from overflowing the glue to the appearance surface. In addition, the manufacturing method has a simple process, high efficiency and low cost, does not require complex design and processing of the mold structure, does not damage the inner surface of the mold, and does not need to add an insert positioning mechanism to achieve the manufacturing of panels with good appearance, thereby greatly improving the product yield.

[0052] In one embodiment, the bonding strength between the adhesive member and the diaphragm is greater than the bonding strength between the adhesive member and the mold. Specifically, bonding strength refers to the bonding force borne on a unit bonding surface. The bonding strength mainly includes the cohesive strength of the adhesive layer and the bonding strength between the adhesive layer and the adhered surface. The stronger the bonding strength, the greater the bonding force between the two, and the more difficult it is to separate. After the adhesive member and the diaphragm are bonded, it is less likely to fall off. Therefore, after the connector is formed by injection molding and the panel is taken out, the adhesive member can be bonded to the panel and taken out together. The present invention provides a side of the adhesive member connected to the diaphragm with a greater bonding strength, thereby ensuring that after the panel is formed and taken out from the mold, the adhesive member remains on the panel and will not remain in the mold, thereby reducing the mold cleaning process and improving the efficiency of the manufacturing process.

[0053] In one implementation, please refer to Figure 2 After the membrane 4 with the adhesive member 1 is placed in the mold, the membrane 4 with the adhesive member 1 separates the inner cavity 3 of the mold to form a first cavity and a second cavity, and the connecting member is injection molded in the second cavity.

[0054] In one embodiment, bonding the adhesive member to the four edges of the membrane includes: bonding the adhesive member to the edge of the membrane; pressing the adhesive member with a first preset pressure to establish a first bonding force between the adhesive member and the membrane.

[0055] In one embodiment, the adhesive member is bonded to the edge of the film, and a front pressure of a first preset pressure is uniformly applied by a roller, and then the adhesive member and the film are left to stand to pre-establish a first bonding force between the adhesive member and the film.

[0056] In one embodiment, the first preset pressure is 10N / cm 2 ~15N / cm 2 Specifically, the first preset pressure may be 10 N / cm 2 , 11N / cm 2 , 12N / cm 2 , 13N / cm 2 , 14N / cm 2 , 15N / cm 2 When the first preset pressure is less than the range, the first adhesive force is too weak and the bonding strength is insufficient; when the first preset pressure is greater than the range, the first adhesive force is too strong, making it difficult to peel off the adhesive component later and possibly causing damage to the membrane.

[0057] In one embodiment, the first adhesive force is 2.5N / cm to 3.5N / cm. Specifically, the first adhesive force may be 2.5N / cm, 2.6N / cm, 2.7N / cm, 2.8N / cm, 2.9N / cm, 3N / cm, 3.1N / cm, 3.2N / cm, 3.3N / cm, 3.4N / cm, and 3.5N / cm. When the first adhesive force is less than this range, the bonding strength is insufficient, and after the plate is removed, part of the adhesive part may remain on the mold; when the first adhesive force is greater than this range, it is difficult to remove the adhesive part later, and the membrane may be damaged.

[0058] In one embodiment, after the adhesive element is pressed with a first preset pressure, it is left to stand for 20 minutes to 40 minutes, and a first adhesive force is established between the adhesive element and the film.

[0059] In one embodiment, placing a film with an adhesive member in a mold includes: spraying a mold release agent in the inner cavity of the mold; placing the film with an adhesive member in the mold; pressing the adhesive member with a second preset pressure to establish a second adhesive force between the adhesive member and the mold.

[0060] In one embodiment, the second preset pressure is 10N / cm 2 ~15N / cm 2 Specifically, the second preset pressure can be 10N / cm 2 , 11N / cm 2 , 12N / cm 2 , 13N / cm 2 , 14N / cm 2 , 15N / cm2 When the second preset pressure is less than the range, the second adhesive force is too weak and the bonding strength is insufficient; when the second preset pressure is greater than the range, the second adhesive force is too strong, making it difficult to remove the adhesive component later and possibly causing damage to the film.

[0061] In one embodiment, the second adhesive force is 0.1N / cm to 0.5N / cm. Specifically, the second adhesive force can be 0.1N / cm, 0.2N / cm, 0.3N / cm, 0.4N / cm, and 0.5N / cm. When the second adhesive force is less than this range, the bonding strength is insufficient, and there may still be a gap between the adhesive member and the mold, resulting in the penetration of the injection liquid; when the second adhesive force is greater than this range, the adhesive member may be left on the mold at a later stage, and the diaphragm may be damaged.

[0062] In one embodiment, a connector is injection molded in a mold, and the connector is connected to a diaphragm to obtain a plate, including: injecting a precursor material of the connector into an inner cavity of the mold; after the precursor material is molded, the connector is connected to the diaphragm to obtain a plate, and an adhesive member is connected to the plate; and the adhesive member is removed from the plate.

[0063] In one embodiment, the movable mold and the fixed mold are closed, and the precursor material of the connecting part is injected to connect with the diaphragm. After maintaining the pressure for 30 seconds, the mold is opened to take out the part. Due to the difference in adhesive force on both sides of the adhesive part, the adhesive can be left on the surface of the plate (diaphragm) in a directional manner during the mold opening process, and then manually removed to ensure that no glue is left to obtain the final product.

[0064] In one embodiment, the precursor material of the connector is consistent with the matrix resin of the diaphragm and is reinforced with 20% to 40% by mass of chopped glass fibers to ensure effective connection between the connector and the diaphragm.

[0065] In one embodiment, the adhesive member is a double-sided strong and weak tape, which includes a first side and a second side facing each other, and the first side has a greater adhesiveness than the second side; the thickness of the double-sided strong and weak tape is less than or equal to 0.05 mm, and the width is less than or equal to 10 mm. This ensures that the adhesive portion does not produce dents on the surface of the product due to excessive injection pressure.

[0066] The technical solution of the present invention is described in detail below through specific embodiments. It should be noted that the following embodiments and comparative examples are selected to describe in detail the manufacturing process of the forged carbon fiber textured door interior trim panel.

[0067] Embodiment 1:

[0068] This embodiment provides a door interior panel (panel) and a manufacturing method, wherein the base resin used in the door interior panel is polypropylene PP, carbon fiber reinforced PP prepreg, the resin content is 40%, and the carbon fiber fabric is carbon fiber twill fabric with a surface density of 200g / m 2 .

[0069] The manufacturing method comprises the following steps:

[0070] 1) The digital model of the door interior panel is expanded in two dimensions in the software to obtain the corresponding plane diagram (with positioning holes), and the corresponding high-speed steel punching tool is developed based on the plane diagram. The carbon fiber reinforced PP prepreg sheet (film) is placed between the concave and convex dies of the punching die, and then the die is closed to blank and punch holes.

[0071] 2) Cover the upper and lower surfaces of the cut prepreg sheet with glass fiber / PTFE release cloth and place it in the hot pressing mold for the surface layer of the product. The mold is heated to 210°C in advance, and the mold is closed and hot pressed after preheating for 2 minutes. To ensure that the fabric texture is not messy, the mold closing pressure must be controlled not to exceed 0.1MPa. Hot press for 3 minutes to form the surface layer of the interior panel, then slowly open the mold to cool, and demold to obtain the carbon fiber membrane.

[0072] 3) Stick the strong adhesive side (adhesive part) of 3M tape to the parts of the film that are prone to warping (the two ends and the middle edge). The tape thickness is 0.025mm, the width is 10mm, and the length of each adhesive part is not less than 100mm. Use a roller to evenly apply 10N / cm 2 ~15N / cm 2 The frontal pressure was then placed for 30 minutes to allow the bonding surface to pre-establish a bonding force of about 3N / cm.

[0073] 4) Spray the release agent in the mold cavity, place the film with the tape in the cavity, peel off the release film on the weak adhesive side and put the weak adhesive side close to the mold surface, and use a roller to evenly apply 10N / cm 2 ~15N / cm 2 The front pressure creates a bonding force of about 0.3N / cm on this surface.

[0074] 5) Close the mold and inject 20% glass fiber reinforced PP composite material (precursor material for connectors), set the three-stage temperature of the injection molding cylinder to 210℃-215℃-210℃, hold the pressure for 30s, cool for 20s, and then open the mold to take out the parts. Due to the difference in adhesion between the two sides, the tape can be oriented and left on the surface of the product, and then manually removed to ensure that there is no glue left on the surface of the product to obtain the final product.

[0075] Comparative Example 1

[0076] This comparative example provides a vehicle door interior trim panel, which is a vehicle door interior trim panel manufactured using existing technology on the market.

[0083] Low temperature impact test

[0084] Place the workpiece in a thermostatic box and set the temperature of the thermostatic box to -40℃. Take it out after 4 hours. Place and fix it with the impacted surface facing up. Use a 500g, 50mm diameter steel ball to naturally drop from 400mm above to the impacted surface. The impact process must be completed within 15s after the workpiece is taken out of the thermostatic box. Then observe the surface condition of the sample.

[0085] Test results: The door interior panel provided in Example 1 did not show any breakage, cracks or fractures. The door interior panel provided in Comparative Example 1 showed any breakage, cracks or fractures.

[0086] In summary, the vehicle door interior panel provided by the present invention is pre-bonded with an adhesive part, and then the membrane bonded with the adhesive part is placed in the mold, so that the membrane and the inner wall of the mold can be connected, thereby avoiding the phenomenon that the membrane warps and does not fit the mold, thereby preventing the injection molding from overflowing the glue to the appearance surface. In addition, the manufacturing method has a simple process, is efficient and low-cost, does not require complex design and processing of the mold structure, does not damage the inner surface of the mold, and does not need to add an insert positioning mechanism to achieve the manufacturing of panels with good appearance, greatly improving the product yield.
