Description
Technical Field
[0001] This application relates to the field of vehicle technology, and in particular to a window assembly, a method for manufacturing the window assembly, and a vehicle. Background Technology
[0002] Currently, corner windows in vehicles are typically made of glass. However, the width of corner window glass is generally less than 150mm, which cannot be produced on some existing production lines, requiring the development of new production lines. This increases production costs, and producing small-sized glass products also presents challenges in quality control. If the corner window material is replaced with a plastic window frame, the glass is prone to deformation. Summary of the Invention
[0003] The purpose of this application is to provide a vehicle window assembly, a method for manufacturing the vehicle window assembly, and a vehicle. This vehicle window assembly can be used as a corner window of a vehicle, which can avoid the problem that glass with a width of less than 150mm cannot be manufactured on existing production lines, and can solve the problem that deformation easily occurs when glass is directly replaced with a plastic window body.
[0004] This application provides a vehicle window assembly for installation on a vehicle. The vehicle window assembly includes a plastic window body, a base layer, and an edging. The base layer is disposed on one side of the plastic window body and is in at least partial contact with the surface of the plastic window body facing the inside of the vehicle. The edging covers the edge of the plastic window body facing the inside of the vehicle.
[0005] The window assembly provided in this application can be used as a corner window of a vehicle. By using a plastic window body instead of glass, the advantages are twofold. First, the plastic window body is made of plastic, avoiding the problem that glass with a width less than 150mm cannot be manufactured on existing production lines, requiring the development of new production lines, which increases costs and makes it difficult to control product quality. Second, plastic is lighter and cheaper than glass, and can be manufactured using automated processes. Furthermore, plastic has higher impact resistance than glass, achieving lightweight and automated production of the window assembly, reducing production costs and improving impact resistance. In addition, by setting a substrate layer on the inner surface of the plastic window body facing the vehicle, the structural strength of the plastic window body can be strengthened, solving the problem of deformation that easily occurs when directly replacing glass with a plastic window body.
[0006] In one possible implementation, the thickness of the substrate layer in the area in contact with the plastic window is the same, which is equivalent to removing the first protrusion on the surface of the substrate layer away from the plastic window. This can avoid the generation of bosses and internal stress during the forming process of the plastic window caused by the first protrusion, thereby avoiding the problem of uneven surface of the plastic window caused by bosses and internal stress.
[0007] In one possible implementation, the plastic window includes a visible area and an edge area, the edge area being disposed around the visible area, and the projection of the substrate layer onto the plastic window covering the visible area.
[0008] In one possible implementation, the thickness of the substrate layer is 1.5 mm to 2.5 mm.
[0009] In one possible implementation, the injection pressure of the plastic window is greater than the injection pressure of the substrate layer.
[0010] In one possible implementation, the material of the plastic window includes at least one of polymethyl methacrylate, polycarbonate, styrene-acrylonitrile copolymer, and polyamide.
[0011] In one possible implementation, the window assembly further includes a first side panel portion, which protrudes from the side of the plastic window body away from the substrate layer. The peripheral side surface of the plastic window body is spaced apart from the first side panel portion, effectively solving the problem of light distortion of the plastic window body caused by the tension force generated on the plastic window body due to the connection between the first side panel portion and the peripheral side surface of the plastic window body.
[0012] In one possible implementation, the width between the peripheral side of the plastic window and the first side enclosure portion is D, where D is 1mm to 5mm.
[0013] In one possible implementation, the window assembly further includes a second side panel portion that protrudes relative to the plastic window body towards the substrate layer. Both the first and second side panel portions are located on the surface of the edging facing the inside of the vehicle to enhance the structural strength of the edging.
[0014] In one possible implementation, the first sidewall portion and the second sidewall portion are integrally formed with the substrate layer.
[0015] In one possible implementation, the window assembly further includes a fastener and a mounting component. The fastener is disposed on the side of the base layer opposite to the plastic window body, and the mounting component is fixedly connected to the side of the fastener opposite to the base layer and is used to mount the window assembly to the vehicle body.
[0016] In one possible implementation, the material of the fastener is the same as the material of the edging, which avoids deformation of the glossy surface of the plastic window during the forming process of the fastener.
[0017] In one possible implementation, the substrate layer has a first snap-fit portion, and the plastic window body has a second snap-fit portion, with the second snap-fit portion snapping into the first snap-fit portion; alternatively, the substrate layer is bonded to the plastic window body; or, the substrate layer and the plastic window body are fused together. This avoids the problem of the plastic window body arching and deforming due to the high injection pressure of the plastic window body causing the substrate layer to be squeezed when directly injection molding the plastic window body onto the substrate layer. Furthermore, since the substrate layer and the plastic window body can be molded separately and then connected, the presence of a first protrusion in the substrate layer and a first side panel in contact with the peripheral side surface of the plastic window body will not affect the surface flatness of the plastic window body, ensuring that the surface flatness of the plastic window body is not affected by the first protrusion and the contact between the peripheral side surface and the first side panel.
[0018] This application embodiment also provides a method for manufacturing a vehicle window assembly, wherein the vehicle window assembly is the above-mentioned vehicle window assembly, and the method for manufacturing the vehicle window assembly includes: The matrix layer is prepared by injection molding; Plastic windows are manufactured using injection molding, with the injection pressure of the plastic window being greater than that of the substrate layer. The edge banding is prepared by injection molding, and the injection pressure of the edge banding is lower than that of the base layer.
[0019] This application provides a method for manufacturing a vehicle window assembly. By setting the injection pressure of the plastic window body to be greater than that of the substrate layer, the molded plastic window body can achieve a high-gloss appearance, thus ensuring that the plastic window body can replace glass. Furthermore, by setting the injection pressure of the edging to be less than that of the substrate layer, the lower injection pressure of the edging results in less pressure on the substrate layer and the plastic window body, preventing surface deformation of the high-gloss plastic window body and ensuring the surface smoothness of the plastic window body.
[0020] In one possible implementation, the injection pressure of the plastic window body is 50 MPa to 80 MPa, and the injection pressure of the edging is 10 MPa to 15 MPa.
[0021] In one possible implementation, the step of preparing the matrix layer by injection molding further includes: The fastener is prepared on the side of the substrate layer away from the plastic window using injection molding, and the injection pressure of the fastener is 10 MPa to 15 MPa. The mounting component is attached to the side of the fastener away from the base layer. The mounting component is used to install the window assembly onto the vehicle body. The fastener has lower molding pressure, which, while working with the mounting component to achieve the function of connecting to the vehicle body, avoids squeezing and deforming the base layer of the base component and the plastic window frame, thus ensuring the surface flatness of the plastic window frame.
[0022] This application embodiment also provides a method for manufacturing a vehicle window assembly, wherein the vehicle window assembly is the above-mentioned vehicle window assembly, and the method for manufacturing the vehicle window assembly includes: The substrate layer and the plastic window are prepared separately; The base layer and the plastic window are assembled to form an intermediate component; Prepare the edging on the middle component.
[0023] This application provides a method for manufacturing a vehicle window assembly. By separately preparing a substrate layer and a plastic window body, and then assembling the substrate layer and the plastic window body, the method avoids the problem of the plastic window body being squeezed due to higher injection pressure than the substrate layer, which could cause the plastic window body to arch and deform. This ensures the surface flatness of the plastic window body. Furthermore, because the substrate layer and the plastic window body are prepared separately and then assembled, the surface flatness of the plastic window body is not affected by the first protrusion or by the contact between the peripheral side of the plastic window body and the first sidewall portion.
[0024] In one possible implementation, the substrate layer is assembled with the plastic window body to form an intermediate component using any of the following methods: snap-fit, heat-fusion, or adhesive bonding.
[0025] This application embodiment also provides a vehicle, including a body and a window assembly, wherein the window assembly is the window assembly described above, or the window assembly is a window assembly manufactured according to the above-described method for manufacturing a window assembly, and the window assembly is installed on the body.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0030] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a structural schematic diagram of vehicle 1 provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shown is a structural schematic of the window assembly 300 in the first embodiment of vehicle 1. Figure 3 for Figure 1 The diagram shows a cross-sectional structure of the window assembly 300.
[0031] This application provides a vehicle 1, which includes a body 100 and a window assembly 300, the window assembly 300 being mounted on the body 100. In this embodiment, the window assembly 300 is described as a corner window of the vehicle 1.
[0032] The window assembly 300 includes a plastic window body 330, a base member 310, and an edge protector 350. The base member 310 is disposed on the inner surface of the plastic window body 330 facing the vehicle 1 and is mounted on the vehicle body 100 to enable the window assembly 300 to be mounted on the vehicle body 100. The plastic window body 330 is mounted on the base member 310, and the edge protector 350 is mounted on the base member 310 and covers the edge of the plastic window body 330.
[0033] Specifically, in this embodiment, the plastic window 330 is plate-shaped, and its outer surface exhibits a high-gloss appearance. The plastic window 330 can be transparent, translucent, or opaque (such as high-gloss black). In this embodiment, the plastic window 330 is approximately triangular, and its surface refractive index reaches or approaches that of glass. The plastic window 330 can be manufactured using injection molding. For example, the injection pressure of the plastic window 330 is 50 MPa to 80 MPa. For example, the material of the plastic window 330 includes at least one of PMMA (Poly(methyl methacrylate), PC (Polycarbonate), AS (Acrylonitrile-Styrene Copolymer), and PA (Polyamide). It should be noted that the plastic window 330 can be made of the same material as the base component 310; in this case, increasing the injection pressure of the molded plastic window 330 achieves the high-gloss surface effect.
[0034] The plastic window 330 includes a visible area P1 and an edge area P2, with the edge area P2 surrounding the visible area P1. The visible area P1 refers to the portion of the plastic window 330 viewed from the outside of the vehicle 1. In this embodiment, "surrounding" includes both complete and partial surrounding. "Edge area P2 surrounding the visible area P1" means that the edge area P2 surrounds the entire circumference of the edge of the visible area P1, or that the edge area P2 surrounds a portion of the edge of the visible area P1. In this embodiment, the plastic window 330 includes a first surface 331, a second surface 333, and a peripheral surface 335. The first surface 331 and the second surface 333 are positioned opposite each other along the thickness direction of the plastic window 330, and the peripheral surface 335 connects the first surface 331 and the second surface 333. The first surface 331 is the outer surface of the plastic window 330 facing the vehicle 1, and the second surface 333 is the inner surface of the plastic window 330 facing the vehicle 1.
[0035] The base component 310 includes a base portion 10 and an edge portion 30, the edge portion 30 being disposed around the base portion 10. "The edge portion 30 is disposed around the base portion 10" means that the edge portion 30 is disposed around the entire circumference of the edge of the base portion 10, or that the edge portion 30 is disposed around a portion of the edge of the base portion 10.
[0036] The substrate 10 includes a first surface 11 and a second surface 13, which are disposed opposite to each other along the thickness direction of the substrate 10. The first surface 11 of the substrate 10 is attached to the second surface 333 of the plastic window 330 to achieve surface contact between the substrate 10 and the inner side of the plastic window 330 facing the vehicle 1. The substrate 10 includes a substrate layer S1 and an edge layer S2, both of which are disposed on the inner side of the plastic window 330 facing the vehicle 1. The substrate layer S1 is at least partially in contact with the inner side of the plastic window 330 facing the vehicle 1, and the projection of the substrate layer S1 onto the plastic window 330 covers the visible area P1 of the plastic window 330. The edge layer S2 is disposed around the substrate layer S1. Preferably, the substrate layer S1 is prepared by injection molding. In this embodiment, the injection pressure of the plastic window 330 is greater than the injection pressure of the substrate layer S1. For example, the injection pressure of the matrix layer S1 is 20 MPa to 40 MPa. For example, the matrix layer S1 is injection molded from a material including ABS (Acrylonitrile Butadiene Styrene Plastic) resin and PC (Polycarbonate) resin.
[0037] The edge portion 30 includes a first side portion 31 and a second side portion 33 connected to the first side portion 31. In this embodiment, the first side portion 31 and the second side portion 33 are integrally formed with the base portion 10, and the base part 310 can be prepared by injection molding. The first side portion 31 and the second side portion 33 are located on opposite sides of the base portion 10 along its thickness direction. The first side portion 31 protrudes relative to the first surface 11 in a direction away from the second surface 13, and the second side portion 33 protrudes relative to the second surface 13 in a direction away from the first surface 11. In this embodiment, the first side portion 31 protrudes relative to the first surface 331 of the plastic window 330, so that the first side portion 31 protrudes relative to the plastic window 330 in a direction away from the base portion 10. The second side portion 33 protrudes relative to the plastic window 330 in a direction towards the base portion 10. In this embodiment, the first side panel 31 is connected to the peripheral side surface 335 of the plastic window 330 so that the peripheral side surface 335 of the plastic window 330 is connected to the edge portion 30.
[0038] The edging 350 covers the edge region P2 of the plastic window 330 to achieve edge coverage of the plastic window 330. In this embodiment, the edging 350 also covers the first side portion 31 and the second side portion 33 of the edge portion 30 in the base member 310. The first side portion 31 and the second side portion 33 are both located on the inner surface of the edging 350 facing the vehicle 1, to enhance the structural strength of the edging 350. The edging 350 can be prepared by injection molding. For example, the injection pressure of the edging 350 is 10 MPa to 15 MPa. For example, the material of the edging 350 includes at least one of TPE (Thermoplastic Elastomer), PVC (Polyvinyl Chloride), and PU (Polyurethane).
[0039] The window assembly 300 provided in this application embodiment can be used as a corner window of vehicle 1. By using a plastic window body 330 instead of glass, the plastic window body 330, made of plastic, avoids the problem that glass with a width less than 150mm cannot be manufactured on existing production lines, requiring the development of new production lines, which would increase costs and make it difficult to control product quality. On the other hand, plastic is lighter and cheaper than glass, and can be manufactured using automated processes. Furthermore, plastic has higher impact resistance than glass, achieving lightweighting and automation of the window assembly 300, reducing production costs and improving impact resistance. In addition, by ensuring that the substrate layer S1 is at least partially in contact with the inner surface of the plastic window body 330 facing vehicle 1, the structural strength of the plastic window body 330 can be strengthened, solving the problem of deformation that easily occurs when glass is directly replaced with a plastic window body 330.
[0040] See Figure 4 , Figure 4 This is a schematic diagram showing the effect of grid-line lighting on a corner window after replacing ordinary glass with a plastic window frame 330. Figure 4 The dashed line represents the projection lines produced by the grid light tubes shining on the plastic window 330.
[0041] In corner windows, if the surface of the plastic window frame 330 is flat, the grid light tubes illuminating it will create regular lines. Users typically require the surface flatness of the plastic window frame 330 to be close to that of glass. The applicant has found that during the development of corner windows, the actual appearance of the plastic window frame 330 may not meet customer requirements, such as... Figure 4 As shown, the high-gloss surface in the middle area of the corner window product showed a wavy shadow under the illumination of the grid line light tube, indicating that the surface flatness of the plastic window 330 in the corner window is not up to standard.
[0042] See also Figure 5 , Figure 5 for Figure 4 The diagram shows a cross-sectional view of a portion of the corner window. To address the issue of surface flatness of the plastic window body 330 in the corner window, the applicant separated the base component 310 from the plastic window body 330. Theoretically, the surface of the plastic window body 330 facing the base component 310 should be flat. However, when the base component 310 has a first protrusion 50, a boss 70 appears on the surface of the plastic window body 330 facing the base component 310 at the position corresponding to the first protrusion 50. The applicant analyzes that the reason for the appearance of the boss 70 in the plastic window body 330 may be that: the base component 310 is usually prepared by injection molding (injection pressure is usually 30 MPa), followed by injection molding to form the plastic window body 330. To achieve the high-gloss appearance of the plastic window body 330, the injection pressure during injection molding of the plastic window body 330 is higher than that of the base component 310, typically 50 MPa to 80 MPa or higher. When injection molding the high-gloss plastic window 330, the injection mold temperature is about 70°C to improve fluidity. The injection pressure of the injection molding of the plastic window 330 will squeeze and deform the base part 310. The deformation space at the position of the first protrusion 50 in the base part 310 is greater than that of other parts, so that the plastic window 330 will have a boss 70 and internal stress at the position of the first protrusion 50. As a result, the surface of the plastic window 330 is uneven after the product is demolded due to the internal stress and the boss 70.
[0043] Following the above research and analysis, the applicant, in order to solve the problem of uneven surface of the plastic window frame 330, provided a second embodiment of the vehicle window assembly 300. (See also...) Figure 6 , Figure 6 for Figure 1 The diagram shows a cross-sectional view of the window assembly 300 in the second embodiment of vehicle 1.
[0044] The difference between the window assembly 300 of the second embodiment and the window assembly 300 of the first embodiment is that, in the window assembly 300 of the second embodiment, the thickness of the base layer S1 of the base member 310 is consistent in the contact area with the plastic window body 330.
[0045] The phrase "the thickness of the substrate layer S1 remains consistent in the contact area with the plastic window 330" means that the substrate layer S1 is of essentially uniform thickness, with a thickness error within ±20%. Even if there are small protrusions on the surface of the substrate layer S1 away from the plastic window 330, it can still be considered as maintaining a consistent thickness, as long as the thickness difference between different areas of the substrate layer S1 is within ±20%. Specifically, in this embodiment, the substrate layer S1 of the substrate portion 10 is approximately plate-shaped, meaning the surface of the substrate layer S1 away from the plastic window 330 is roughly flat. Maintaining a consistent thickness of the substrate layer S1 in the contact area with the plastic window 330 in the substrate component 310 avoids localized shrinkage and deformation caused by uneven thickness of the substrate layer S1 itself. Maintaining a consistent thickness in the contact area between the substrate layer S1 and the plastic window frame reduces localized stress concentration and prevents the injection pressure of the injection-molded plastic window frame 330 from deforming the substrate component 310, thus preventing the plastic window frame 330 from developing a boss 70 (see...). Figure 5 This improves the surface flatness of the plastic window 330, i.e., the first surface 331. In this embodiment, the thickness of the plastic window 330 is 2.0mm~3.0mm, and the thickness of the substrate layer S1 is 1.5mm~2.5mm.
[0046] In the window assembly 300 provided in this embodiment, by setting the thickness of the contact area between the base layer S1 in the base part 10 of the base member 310 and the plastic window 330 to be the same, it is equivalent to removing the first protrusion 50 on the surface of the base layer S1 away from the plastic window 330. This can avoid the generation of boss 70 and internal stress during the molding process of the plastic window 330 due to the first protrusion 50, thereby avoiding the problem of uneven surface of the plastic window 330 caused by the boss 70 and internal stress.
[0047] Continue reading Figure 4 The applicant also discovered that the highlighted areas around the plastic window frame 330 in the corner window exhibited more pronounced grid wavy lines under the illumination of the grid-lined light tubes. (See also...) Figure 7 , Figure 7 for Figure 4 The diagram shows a cross-sectional view of another part of the corner window. After the applicant separated the base component 310 from the plastic window body 330 in the corner window, it was found that the first side portion 31 of the base component 310 was in contact with the peripheral side surface 335 of the plastic window body 330, and the peripheral side surface 335 of the plastic window body 330 was concave. The applicant analyzed that the reason for the concavity of the peripheral side surface 335 of the plastic window body 330 may be: the injection pressure during the injection molding of the plastic window body 330 compresses and deforms the base component 310, generating internal stress (such as...). Figure 7(The solid line arrow points in the direction of the product) so that after the product is demolded, the stress forces the product to deform a second time, causing the plastic window 330 to deform along the thickness direction and the side direction. The upper and lower surfaces of the plastic window 330 along the thickness direction and away from the peripheral side surface 335 are not affected by the tensile force of the base component 310, therefore the upper and lower surfaces of the plastic window 330 away from the peripheral side surface 335 do not undergo glossy deformation. However, the portion of the plastic window 330 close to the peripheral side surface 335 experiences simultaneous deformation along the side direction and deformation along the thickness direction. The side surface of the first sidewall portion 31 of the base component 310 and the bottom surface of the base portion 10 are connected to the plastic window 330, generating tensile force. The released force results in an arched deformation around the perimeter of the plastic window 330, producing a more severe glossy surface curvature.
[0048] Based on the above research and analysis, the applicant, in order to solve the problem of severe optical distortion in the peripheral area of the plastic window 330's appearance surface caused by the contact between the peripheral side surface 335 of the plastic window 330 and the side surface of the first side portion 31 of the base member 310, provides a third embodiment of a vehicle window assembly 300. (See also...) Figure 8 and Figure 9 , Figure 8 for Figure 1 The diagram shows a cross-sectional view of the window assembly 300 in the third embodiment of vehicle 1. Figure 9 for Figure 8 The exploded structural diagram of the window assembly 300 shown.
[0049] The difference between the window assembly 300 of the third embodiment and the window assembly 300 of the first embodiment is that, in the window assembly 300 of the third embodiment, the peripheral side 335 of the plastic window body 330 and the first side portion 31 of the base member 310 are spaced apart.
[0050] Specifically, in the window assembly 300 of the third embodiment, the base layer S1 of the base part 10 in the base member 310 includes a first base part 101 and a first protruding part 50, the first protruding part 50 protruding from the first base part 101 on the side away from the plastic window body 330. The edge layer S2 includes a second base part 102 and a second protruding part 60, the second base part 102 being connected to the first base part 101, and the second protruding part 60 protruding from the second base part 102 on the side away from the plastic window body 330. In this embodiment, the first base part 101, the first protruding part 50, the second base part 102, and the second protruding part 60 are integrally formed. The first protruding part 50 is disposed opposite to the plastic window body 330. For example, both the first protruding part 50 and the second protruding part 60 can be ribs, connecting columns, or other structures. Ribs are used to improve the structural strength of the base part 10 and prevent deformation of the base part 10. The connecting column is used to connect with the sheet metal structure of the body 100 so that the base component 310 can be installed on the body 100.
[0051] A gap 35 is formed between the peripheral side surface 335 of the plastic window 330 and the first side panel portion 31. For example, the width of the gap between the peripheral side surface 335 of the plastic window 330 and the first side panel portion 31 is D, where D = 1mm to 5mm, meaning the width of the gap 35 is 1mm to 5mm. In this embodiment, the edging 350 fills the gap 35 and is connected to the peripheral side surface 335 of the plastic window 330.
[0052] To verify the impact of the connection between the base component 310 and the peripheral side surface 335 of the plastic window 330 in the window assembly 300, this embodiment uses injection molding to injection mold the plastic window 330 onto the base component 310. After the plastic window 330 is ejected from the mold, its peripheral side surface 335 is immediately separated from the base component 310, thus obtaining a first intermediate assembly formed by assembling the plastic window 330 and the base component 310. Simultaneously, the plastic window 330 is injection molded onto the base component 310, and after ejection, a second intermediate assembly formed by assembling the plastic window 330 and the base component 310 is obtained. After the deformation of the first and second intermediate assemblies stabilizes, they are illuminated with a grid light tube for comparison. Experimental results show that the lines on the plastic window 330 in the first intermediate component illuminated by the grid light are more regular than the lines on the plastic window 330 in the second intermediate component. The experimental results indicate that disconnecting the peripheral side 335 of the plastic window 330 from the first side portion 31 of the base component 310, that is, setting the peripheral side 335 of the plastic window 330 and the first side portion 31 separately, can effectively solve the problem of the plastic window 330 being subjected to tensile force due to the connection between the first side portion 31 and the peripheral side 335 of the plastic window 330, which causes light distortion of the plastic window 330.
[0053] See Figure 10 , Figure 10 for Figure 1 A schematic diagram of the cross-sectional structure of the window assembly 300 in the fourth embodiment of the vehicle 1 shown.
[0054] The difference between the window assembly 300 of the fourth embodiment and the window assembly 300 of the third embodiment is that, in the window assembly 300 of the fourth embodiment, the thickness of the base layer S1 of the base part 10 in the base member 310 is consistent in the contact area with the plastic window 330.
[0055] Specifically, in the window assembly 300 of the fourth embodiment, the base layer S1 of the base part 10 of the base member 310 is roughly flat away from the surface of the plastic window body 330, which is equivalent to the first protrusion 50 being eliminated.
[0056] In the window assembly 300 provided in this embodiment, on the one hand, by setting the thickness of the base layer S1 in the base part 10 of the base member 310 to be consistent with the thickness in the contact area with the plastic window 330, that is, it is equivalent to canceling the first protrusion 50 on the surface of the base layer S1 away from the plastic window 330. Therefore, it is possible to avoid the generation of boss 70 and internal stress during the forming process of the plastic window 330 due to the first protrusion 50, thereby avoiding the problem of uneven surface of the plastic window 330 caused by the boss 70 and internal stress. On the other hand, the peripheral side surface 335 of the plastic window 330 is also set to be spaced apart from the first side part 31 of the base member 310, avoiding the pulling force of the base member 310 on the plastic window 330, thereby avoiding the plastic window 330 from arching deformation, and further ensuring the surface flatness of the plastic window 330.
[0057] Continue reading Figure 10 The applicant's analysis revealed that during the fabrication of the window assembly 300, the injection pressure of the edging 350 was 10 MPa to 15 MPa. The injection pressure of the edging 350 was lower than that of the base component 310, which in turn was lower than that of the plastic window 330. This lower molding pressure of the edging 350 resulted in less extrusion pressure on the surfaces and sides of the base component 310 and the plastic window 330. Therefore, the contact between the edging 350 and the peripheral side surface 335 of the plastic window 330 during molding would not cause deformation of the high-gloss surface of the plastic window 330. In this case, it is possible to consider providing a structural component made of a material with a lower molding pressure, similar to that of the edging 350, in the base layer S1 of the base portion 10 of the base component 310. This would achieve functions that the base component 310 and the plastic window 330 cannot perform while avoiding extrusion deformation of the base component 310 and the plastic window 330. Therefore, this application provides a fifth embodiment of the window assembly 300.
[0058] For details, please refer to Figure 11 , Figure 11 for Figure 1 The diagram shows a cross-sectional view of the window assembly 300 in the fifth embodiment of the vehicle 1 shown. The difference between the window assembly 300 in the fifth embodiment and the window assembly 300 in the fourth embodiment is that the window assembly 300 in the fifth embodiment further includes a mounting assembly 370 for connecting to the vehicle body 100.
[0059] The mounting assembly 370 includes a fastener 371 and a mounting member 373. The fastener 371 is disposed on the surface of the substrate layer S1 in the substrate portion 10 facing away from the plastic window 330, so that the fastener 371 is mounted on the side of the substrate portion 10 facing away from the plastic window 330. The injection pressure of the fastener 371 is less than the injection pressure of the substrate member 310, and the injection pressure of the fastener 371 is greater than the injection pressure of the plastic window 330. For example, the injection pressure of the fastener 371 is 10 MPa to 15 MPa. In this embodiment, the material of the fastener 371 is the same as the material of the edging 350. For example, the material of the fastener 371 includes at least one of TPE (Thermoplastic Elastomer), PVC (Polyvinyl Chloride), and PU (Polyurethane).
[0060] Mounting member 373 is fixedly connected to the side of fixing member 371 away from base part 10, and is used to install window assembly 300 onto vehicle body 100. In this embodiment, mounting member 373 is a nail post, and mounting member 373 is connected to vehicle body 100 to realize the installation of mounting assembly 370 onto vehicle body 100.
[0061] The window assembly 300 provided in this embodiment is mounted on the vehicle body 100 by setting a fastener 371 and a mounting component 373. The injection pressure of the fastener 371 is lower than that of the base component 310, and the injection pressure of the fastener 371 is greater than that of the plastic window body 330, thus preventing deformation of the high-gloss surface of the plastic window body 330 during the molding process of the fastener 371.
[0062] See Figure 12 , Figure 12 for Figure 1 A schematic diagram of the cross-sectional structure of the window assembly 300 in the sixth embodiment of the vehicle 1 shown.
[0063] The difference between the window assembly 300 of the sixth embodiment and the window assembly 300 of the third embodiment is that the assembly method of the base component 310 and the plastic window 330 in the window assembly 300 of the sixth embodiment is different from the assembly method of the base component 310 and the plastic window 330 in the window assembly 300 of the third embodiment.
[0064] Specifically, in the sixth embodiment of the window assembly 300, the base layer S1 of the base member 310 is provided with a first snap-fit portion 91. The plastic window body 330 is provided with a second snap-fit portion 92, which snaps into the first snap-fit portion 91 to realize the installation of the plastic window body 330 on the base member 310. In this embodiment, the first snap-fit portion 91 is a snap-fit hole, which is provided in the base member 10 and penetrates the base layer S1 along the thickness direction of the base layer S1 of the base member 10. The second snap-fit portion 92 is a buckle, which is provided on the side of the plastic window body 330 facing the base member 10. By snapping the buckle into the snap-fit hole of the base member 310, the plastic window body 330 is snapped into the base layer S1. In this embodiment, the peripheral side surface 335 of the plastic window 330 is spaced apart from the first side portion 31 of the base component 310. It can be understood that the peripheral side surface 335 can also contact and connect with the first side portion 31 at this time, and this embodiment does not limit this.
[0065] It is understood that in other embodiments, the base layer S1 of the base component 310 may not have the first snap-fit portion 91, and the plastic window 330 may not have the second snap-fit portion 92. The plastic window 330 can be installed on the base component 310 by bonding the base layer S1 of the base component 310 to the plastic window 330 with adhesive, or by fusing the base layer S1 of the base component 310 to the plastic window 330.
[0066] In the window assembly 300 provided in this embodiment, the base layer S1 of the base component 310 and the plastic window 330 can be molded separately, and then assembled by snap-fit, adhesive, or hot-melt methods. This avoids the problem of the plastic window 330 arching and deforming due to the high injection pressure of the plastic window 330 when directly injection molding the base layer S1 of the base component 310. Furthermore, since the base layer S1 of the base component 310 and the plastic window 330 can be molded separately and then connected, a first protrusion 50 (see [reference]) is provided in the base layer S1 of the base component 310. Figure 5 The fact that the first side portion 31 of the base component 310 contacts the peripheral side surface 335 of the plastic window 330 will not affect the surface flatness of the plastic window 330, thus ensuring that the surface flatness of the plastic window 330 is not affected by the contact between the first protrusion 50 and the peripheral side surface 335 and the first side portion 31.
[0067] See Figure 13 , Figure 13 for Figure 1 A schematic diagram of the cross-sectional structure of the window assembly 300 in the seventh embodiment of the vehicle 1 shown.
[0068] The difference between the window assembly 300 of the seventh embodiment and the window assembly 300 of the second embodiment is that the window assembly 300 of the seventh embodiment transmits light at the position of the plastic window 330.
[0069] Specifically, in the window assembly 300 of the seventh embodiment, the base member 310 is provided with a window 15, which is provided in the base layer S1 of the base part 10 and penetrates the base part 10 along the thickness direction of the base layer S1.
[0070] The plastic window 330 is a light-transmitting component, covering the window 15, with the visible area P1 of the plastic window 330 exposed relative to the window 15. Exemplarily, the material of the plastic window 330 includes at least one of PMMA (Poly(methyl methacrylate), PC (Polycarbonate), AS (Acrylonitrile-Styrene Copolymer), and PA (Polyamide). Since the plastic window 330 is transparent and allows light to pass through, it can replace glass to achieve a light-transmitting effect. In this embodiment, the plastic window 330 is a pressed sheet, i.e., formed under pressure. The high-gloss effect of the pressed sheet is currently the best available, achieving the same level as glass. Therefore, the molded surface of the plastic window 330 easily meets the high-gloss requirements.
[0071] At this time, the connection between the window assembly 300 and the vehicle body 100 can be achieved by providing a mounting assembly 370 on the second surface 333 of the plastic window 330 facing the base portion 10. The mounting assembly 370 passes through the window 15 and protrudes relative to the second surface 13 of the base portion 10. The fastener 371 in the mounting assembly 370 is connected to the second surface 333 of the plastic window 330 facing the base layer S1. The structure of the mounting assembly 370 is the same as that of the mounting assembly 370 in the window assembly 300 of the fifth embodiment, and can be set with reference to the fifth embodiment; further details are omitted here.
[0072] See Figure 14 , Figure 14 The flowchart of the method for preparing the window assembly 300 provided in the embodiments of this application is shown in the first embodiment.
[0073] This application embodiment also provides a method for manufacturing the above-mentioned window assembly 300, including: S10, The matrix layer S1 is prepared by injection molding.
[0074] For example, the injection pressure of the matrix layer S1 is 20 MPa to 40 MPa. In this embodiment, the injection pressure of the matrix layer S1 is about 30 MPa.
[0075] S20. A plastic window 330 is prepared on the substrate layer S1 by injection molding, wherein the injection pressure of the plastic window 330 is greater than the injection pressure of the substrate layer S1.
[0076] The injection pressure of the plastic window 330 is greater than that of the substrate layer S1 to achieve a high-gloss appearance. For example, the injection pressure of the plastic window 330 is 50 MPa to 80 MPa, or even higher.
[0077] S30. The edge banding 350 is prepared by injection molding, and the injection pressure of the edge banding 350 is less than the injection pressure of the matrix layer S1.
[0078] For example, the injection pressure of the 350mm edge is 10MPa~15MPa.
[0079] In some embodiments, after the step of preparing the matrix layer S1 by injection molding, the method further includes: A fastener 371 is prepared on the side of the base portion 10 of the base part 310 away from the plastic window 330 by injection molding. The injection pressure of the fastener 371 is 10 MPa to 15 MPa. The mounting component 373 is connected to the side of the base portion 10 of the fixing component 371 away from the base component 310. The mounting component 373 is used to install the window assembly 300 onto the body 100 of the vehicle 1.
[0080] The structures of the fastener 371 and the mounting component 373 can be referred to those of the fastener 371 and the mounting component 373 in the fifth embodiment, and will not be described again here. This embodiment provides a method for manufacturing a vehicle window assembly 300. By setting the injection pressure of the plastic window body 330 to be greater than the injection pressure of the substrate layer S1, the molded plastic window body 330 can exhibit a high-gloss appearance, thereby ensuring that the plastic window body 330 can be used as a substitute for glass. In addition, by setting the injection pressure of the edge banding 350 to be less than the injection pressure of the substrate layer S1, the lower injection pressure of the edge banding 350 results in less extrusion pressure on the substrate layer S1 and the plastic window body 330, preventing surface deformation of the high-gloss plastic window body 330 and ensuring the surface flatness of the plastic window body 330.
[0081] In addition, by setting the injection pressure of the fastener 371 to 10Mpa~15Mpa, the molding pressure of the fastener 371 is relatively small. While cooperating with the mounting part 373 to achieve the function of connecting with the body 100, it avoids the extrusion and deformation of the base layer S1 of the base part 310 and the plastic window 330, thereby ensuring the surface flatness of the plastic window 330.
[0082] See Figure 15 , Figure 15 The method for preparing the window assembly 300 provided in this application embodiment is shown in the flowchart of the second embodiment.
[0083] This application embodiment also provides a method for manufacturing the above-mentioned window assembly 300, including: P10. Prepare the substrate layer S1 and the plastic window 330 respectively.
[0084] For example, the substrate layer S1 and the plastic window 330 can be prepared by injection molding. For example, the injection pressure of the substrate layer S1 is 20 MPa to 40 MPa, and the injection pressure of the plastic window 330 is 50 MPa to 80 MPa.
[0085] P20. Assemble the substrate layer S1 and the plastic window 330 to form an intermediate component.
[0086] For example, the substrate layer S1 and the plastic window 330 can be assembled to form an intermediate component using any of the following methods: snap-fit, heat fusion, or adhesive bonding. The snap-fit method can refer to the assembly method of the substrate layer S1 of the substrate member 310 and the plastic window 330 in the vehicle window assembly 300 of the sixth embodiment described above.
[0087] P30, Prepare a 350mm edging on the intermediate component.
[0088] For example, the edge banding 350 can be prepared by injection molding. For example, the injection pressure of the edge banding 350 is 10 MPa to 15 MPa.
[0089] This embodiment provides a method for manufacturing a vehicle window assembly 300. By separately manufacturing the substrate layer S1 of the substrate component 310 and the plastic window 330, and then assembling the substrate layer S1 of the substrate component 310 with the plastic window 330, the problem of the plastic window 330 arching and deforming due to the higher injection pressure of the plastic window 330 than that of the substrate layer S1 is avoided. This ensures the surface flatness of the plastic window 330. Furthermore, since the substrate layer S1 of the substrate component 310 and the plastic window 330 are manufactured separately and then assembled, the surface flatness of the plastic window 330 is not affected by the first protrusion 50 in the substrate layer S1 or by the contact between the peripheral side surface 335 of the plastic window 330 and the first sidewall portion 31 of the substrate component 310 is ensured.
