Description

Technical Field

[0001] This application relates to the field of composite material technology, and in particular to a method for manufacturing a vehicle roof and a vehicle thereof. Background Technology

[0002] With the development of automotive technology and the expansion of its functions, as well as the improvement of people's living standards, the proportion of vehicles with large sunroofs and panoramic sunroofs is increasing. Currently, the mainstream manufacturing process for vehicle roofs is a molding method using PU substrate and fabric. Due to the large opening of the sunroof, a reinforcing frame for the sunroof needs to be added to the back of the roof body to meet the strength and contour requirements of the sunroof opening.

[0003] In related technologies, the reinforcing frame can be either a metal reinforcing frame or a plastic reinforcing frame. However, metal reinforcing frames increase the weight of the vehicle roof, while plastic reinforcing frames have higher mold costs, resulting in higher production costs for vehicle roofs. Summary of the Invention

[0004] In view of this, this application provides a method for manufacturing a vehicle roof and a vehicle, which can ensure the structural stability of the vehicle roof, achieve a lightweight design of the vehicle roof, and reduce the production cost of the vehicle roof by adapting to automated production lines.

[0005] This application provides a method for manufacturing a vehicle roof, comprising: providing a substrate; forming a target material layer on the substrate; forming a first reinforcing layer on the side of the target material layer away from the substrate; and forming other material layers on the side of the first reinforcing layer away from the substrate; wherein the substrate, the target material layer, and the other material layers together constitute a substrate portion, the substrate portion includes a through sunroof opening, and a first support portion and a second support portion are formed around the periphery of the substrate portion forming the sunroof opening, and the first reinforcing layer is formed on the first support portion and / or the second support portion.

[0006] Compared with related technologies, the embodiments of this application have at least the following advantages: the substrate, the target material layer, and other material layers together constitute the base material portion. Since the base material portion surrounds the periphery forming the sunroof opening, a first support portion and a second support portion are formed. By providing a first reinforcing layer between adjacent material layers of the first support portion and / or the second support portion, the area of ​​the vehicle roof used for installing the sunroof is structurally reinforced to meet the strength requirements of this area after the removal of the reinforcing frame, thereby ensuring the structural stability of the vehicle roof. In addition, compared with a roof with a reinforcing frame, a vehicle roof with a first reinforcing layer formed between adjacent material layers is less expensive, lighter, and does not require a separate installation step, simplifying the installation process and improving assembly efficiency.

[0007] In some possible implementations, the substrate includes a first nonwoven fabric layer, a first glass fiber layer, a first adhesive layer, a substrate, a second adhesive layer, a second glass fiber layer, and a second nonwoven fabric layer stacked together; the first reinforcing layer is formed between the first nonwoven fabric layer and the first glass fiber layer, and / or between the first glass fiber layer and the first adhesive layer, and / or between the second adhesive layer and the second glass fiber layer, and / or between the second glass fiber layer and the second nonwoven fabric layer.

[0008] In some possible implementations, a second reinforcing layer is also included, which is also formed between the first adhesive layer and the substrate, and / or between the second adhesive layer and the substrate.

[0009] In some possible implementations, the first reinforcing layer is a glass fiber layer and the second reinforcing layer is an adhesive layer.

[0010] In some possible implementations, the glass fiber layer is located in the first support portion, and the adhesive layer is located in the second support portion.

[0011] In some possible implementations, the glass fiber density of the glass fiber layer is different from that of the first glass fiber layer and the second glass fiber layer.

[0012] In some possible implementations, the glass fiber layer is formed between the second adhesive layer and the second glass fiber layer, and / or between the second glass fiber layer and the second nonwoven fabric layer; the formation of the first reinforcing layer on the side of the target material layer away from the substrate includes: forming the glass fiber layer on a material layer in the same layer as the first support portion and the second adhesive layer, and / or forming the glass fiber layer on a material layer in the same layer as the first support portion and the second glass fiber layer.

[0013] In some possible implementations, the manufacturing method further includes: forming a reinforcing adhesive layer on a material layer that is the same as the first carrier portion and the substrate, or forming a reinforcing adhesive layer on a material layer that is the same as the first carrier portion and the second adhesive layer.

[0014] In some possible implementations, the step of forming a target material layer on the substrate; forming a first reinforcing layer on the side of the target material layer away from the substrate; and forming other material layers on the side of the first reinforcing layer away from the substrate includes: spraying adhesive onto the upper and lower sides of the substrate and then performing a roll adhesive treatment to form a first adhesive layer and a second adhesive layer on the upper and lower sides of the substrate; stacking the first nonwoven fabric layer and the first glass fiber layer on the side of the first adhesive layer away from the substrate, stacking the second glass fiber layer and the second nonwoven fabric layer on the side of the second adhesive layer away from the substrate, and placing the first reinforcing layer between the first nonwoven fabric layer and the first glass fiber layer, and / or between the first glass fiber layer and the first adhesive layer, and / or between the second adhesive layer and the second glass fiber layer, and / or between the second glass fiber layer and the second nonwoven fabric layer to form a body to be molded; and hot-molding the body to be molded at a preset temperature and preset pressure, and holding the pressure for a preset time.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0038] Please refer to Figure 1 This is a flowchart illustrating a method for manufacturing a vehicle roof according to an embodiment of this application. Figure 1 As shown, it includes the following steps:

[0039] Provide substrate.

[0040] In some embodiments, such as Figure 3 As shown, the substrate 14 is a PU (Polyurethane) or PET (Polyethylene terephthalate) board, and the thickness of the substrate 14 is 4mm to 8mm, for example, 5mm, 6mm or 8mm.

[0041] In some embodiments, the density of substrate 14 is 20 kg / m³. 3 ~35kg / m 3 This embodiment does not specify a particular density for the substrate 14, for example, 23 kg / m³. 3 24kg / m 3 25kg / m 3Or 26kg / m 3 .

[0042] A target material layer is formed on the substrate.

[0043] A first reinforcing layer is formed on the side of the target material layer away from the substrate.

[0044] Other material layers are formed on the side of the first reinforcing layer away from the substrate.

[0045] Specifically, such as Figure 6 As shown, substrate 14, target material layer and other material layers together constitute substrate part 1. Substrate part 1 includes a through skylight opening 10. A first support part 101 and a second support part 102 are formed around the periphery of the skylight opening 10. A first reinforcing layer 21 is formed on the first support part 101 and / or the second support part 102.

[0046] In some embodiments, the target material layer and other material layers include a first nonwoven layer 11, a first glass fiber layer 12, a first adhesive layer 13, a second adhesive layer 15, a second glass fiber layer 16, and a second nonwoven layer 17; from Figure 3 As can be seen, the first nonwoven fabric layer 11, the first glass fiber layer 12, and the first adhesive layer 13 are stacked sequentially on one side of the substrate 14, and the second adhesive layer 15, the second glass fiber layer 16, and the second nonwoven fabric layer 17 are stacked sequentially on the other side opposite to the substrate 14.

[0047] It should be noted that the specific composition of the target material layer and other material layers, as well as how the target material layer, the first reinforcing layer 21 and other material layers are formed, are described in detail in subsequent embodiments. To avoid repetition, they will not be repeated here.

[0048] In some embodiments, the first reinforcing layer 21 is formed between the first nonwoven layer 11 and the first glass fiber layer 12, and / or between the first glass fiber layer 12 and the first adhesive layer 13, and / or between the second adhesive layer 15 and the second glass fiber layer 16, and / or between the second glass fiber layer 16 and the second nonwoven layer 17.

[0049] It is understood that the first support portion 101 and the second support portion 102 are both part of the substrate portion 1. Since the substrate portion 1 is a multi-film structure composed of a substrate 14 and multiple material layers, the first support portion 101 and the second support portion 102 are also the same multi-film structure as the substrate portion.

[0050] The first reinforcing layer 21 is formed between the first nonwoven fabric layer 11 and the first glass fiber layer 12, that is, the first reinforcing layer 21 is formed on the same material layer as the first support portion 101 and the first nonwoven fabric layer 11; the first reinforcing layer 21 is formed between the first glass fiber layer 12 and the first adhesive layer 13, that is, the first reinforcing layer 21 is formed on the same material layer as the first support portion 101 and the first glass fiber layer 12; the first reinforcing layer 21 is formed between the second adhesive layer 15 and the second glass fiber layer 16, that is, the first reinforcing layer 21 is formed on the same material layer as the first support portion 101 and the second adhesive layer 15; the first reinforcing layer 21 is formed between the second glass fiber layer 16 and the second nonwoven fabric layer 17, that is, the first reinforcing layer 21 is formed on the same material layer as the first support portion 101 and the second glass fiber layer 16.

[0051] Compared with related technologies, the embodiments of this application have at least the following advantages: Since the base material portion 1 surrounds the periphery forming the sunroof opening 10, with a first supporting portion 101 and a second supporting portion 102, a first reinforcing layer 21 is provided between adjacent material layers of the first supporting portion 101 and / or the second supporting portion 102 to structurally reinforce the area of ​​the vehicle roof used for installing the sunroof, thus meeting the strength requirements after the removal of the reinforcing frame in this area, thereby ensuring the structural stability of the vehicle roof. Furthermore, compared to roofs with reinforcing frames, vehicle roofs with a first reinforcing layer 21 formed between adjacent material layers are lower in cost, lighter in weight, and do not require a separate installation step, simplifying the installation process and improving assembly efficiency.

[0052] Please refer to Figure 2 This is a flowchart illustrating a method for manufacturing a vehicle roof according to an embodiment of this application. This embodiment further explains the foregoing embodiments, specifically illustrating a particular composition of the target material layer and other material layers, and how the target material layer, the first reinforcing layer, and other material layers are formed.

[0053] The specific process of this embodiment is as follows: Figure 2 As shown, it includes the following steps:

[0054] Provide substrate.

[0055] After spraying adhesive onto the top and bottom sides of the substrate, a roll adhesive process is performed to form a first adhesive layer and a second adhesive layer located on the top and bottom sides of the substrate.

[0056] In some embodiments, after spraying adhesive on the upper and lower sides of the substrate 14, the substrate 14 is then controlled to pass through a roll-on adhesive line to form a first adhesive layer 13 and a second adhesive layer 15.

[0057] In some embodiments, the first adhesive layer 13 and the second adhesive layer 15 serve to bond the materials of the first adhesive layer 13 and the second adhesive layer 15, including but not limited to PA film, PE film or PP film, etc., and the first adhesive layer 13 and the second adhesive layer 15 are preferably PA film.

[0058] In some embodiments, the weight per unit area of ​​the first adhesive layer 13 is 130 g / m². 2 ~260g / m 2 This embodiment does not specify a particular weight per unit area of ​​the first adhesive layer 13, for example, 130 g / m². 2 160g / m 2 180g / m 2 Or 220g / m 2 .

[0059] In some embodiments, the weight per unit area of ​​the second adhesive layer 15 is 100 g / m². 2 ~240g / m 2 This embodiment does not specify a particular weight per unit area of ​​the second adhesive layer 15, for example, 110 g / m². 2 160g / m 2 180g / m 2 Or 220g / m 2 .

[0060] The first nonwoven fabric layer, the first reinforcing layer, and the first glass fiber layer are stacked on the side of the first adhesive layer away from the substrate, and the second glass fiber layer and the second nonwoven fabric layer are stacked on the side of the second adhesive layer away from the substrate to form the body to be molded.

[0061] Specifically, the target material layers in this embodiment include a first adhesive layer 13, a second adhesive layer 15, a first nonwoven fabric layer 11, a second glass fiber layer 16, and a second nonwoven fabric layer 17, while other material layers include a first glass fiber layer 12. That is, after forming the first adhesive layer 13 and the second adhesive layer 15 on the upper and lower sides of the substrate 14, the second glass fiber layer 16 and the second nonwoven fabric layer 17 are stacked on the side of the substrate 14 where the second adhesive layer 15 is formed. The first nonwoven fabric layer 11 is placed on the side of the substrate 14 where the first adhesive layer 13 is formed. Then, the first reinforcing layer 21 is placed on the side of the first nonwoven fabric layer 11 near the substrate 14. Finally, the first glass fiber layer 12 is placed on the side of the first reinforcing layer 21 near the substrate 14, forming the final body to be molded.

[0062] Please refer to Figure 3The substrate 1 includes a first nonwoven fabric layer 11, a first glass fiber layer 12, a first adhesive layer 13, a substrate 14, a second adhesive layer 15, a second glass fiber layer 16, and a second nonwoven fabric layer 17 stacked together; a first reinforcing layer 21 is disposed between the first nonwoven fabric layer 11 and the first glass fiber layer 12.

[0063] The specific location of the first reinforcing layer 21 is described in detail in subsequent embodiments, and will not be repeated here to avoid repetition.

[0064] In some embodiments, the first glass fiber layer 12 and the second glass fiber layer 16 are both layered structures made of glass fibers, preferably alkali-free glass fibers or medium-alkali glass fibers with a length of 10-100 mm.

[0065] In some embodiments, the weight per unit area of ​​the first glass fiber layer 12 and the second glass fiber layer 16 is 130 g / m². 2 ~220g / m 2 This embodiment does not specifically limit the unit area weight of the first glass fiber layer 12 and the second glass fiber layer 16, for example, to 130 g / m². 2 140g / m 2 160g / m 2 Or 180g / m 2 .

[0066] It is understandable that, in the same vehicle roof, the unit area weight of the first fiberglass layer 12 and the second fiberglass layer 16 can be the same or different, depending on the actual needs.

[0067] In some embodiments, the first nonwoven layer 11 and the second nonwoven layer 17 are both made of polyester fiber or polyester fiber. Nonwoven fabric is a fabric that does not require spinning and weaving. It is formed by arranging short textile fibers or filaments in a directional or random manner to form a web structure, and then reinforcing it by mechanical, thermal bonding or chemical methods.

[0068] In some embodiments, the unit area weight of the first nonwoven layer 11 and the second nonwoven layer 17 is 45 g / m². 2 ~80g / m 2 This embodiment does not specifically limit the unit area weight of the first nonwoven fabric layer 11 and the second nonwoven fabric layer 17, for example, to 50 g / m². 2 55g / m 2 60g / m 2 Or 70g / m 2 .

[0069] It is understandable that, in the same vehicle roof, the unit area weight of the first nonwoven fabric layer 11 and the second nonwoven fabric layer 17 can be the same or different, depending on the actual needs.

[0070] In some embodiments, the first reinforcing layer 21 is a glass fiber layer, which is a layered structure composed of glass fibers. The glass fibers are preferably alkali-free or medium-alkali glass fibers with a length of 10-100 mm.

[0071] In some embodiments, the weight per unit area of ​​the first reinforcing layer 21 is 130 g / m². 2 ~150g / m 2 This embodiment does not specify a particular weight per unit area of ​​the first reinforcing layer 21; for example, it can be 130 g / m². 2 135g / m 2 140g / m 2 Or 145g / m 2 .

[0072] In some embodiments, when the first reinforcing layer 21 is a glass fiber layer, the glass fiber density of the glass fiber layer 21 is less than the glass fiber density of the first glass fiber layer 12 and the second glass fiber layer 16. In this way, the structural strength of the vehicle roof can be improved while further achieving a lightweight design for the vehicle roof.

[0073] The body to be molded is hot-molded under preset temperature and preset pressure, and the pressure is held for a preset time.

[0074] In some embodiments, the preset temperature, preset pressure, and preset time can all be set according to actual needs, and this embodiment does not impose any specific limitations on them.

[0075] In some embodiments, after the body to be formed is held under pressure for a preset time, adhesive is sprayed onto the side of the second nonwoven fabric layer 17 away from the substrate 14 to form a fabric adhesive layer 18, and then a fabric layer 19 is formed on the side of the fabric adhesive layer 18 away from the substrate 14, thereby completing the production of the entire vehicle roof.

[0076] Please see again Figure 3 The substrate 1 also includes a fabric adhesive layer 18 and a fabric layer 19; the fabric adhesive layer 18 is disposed on the side of the second nonwoven fabric layer 17 away from the second glass fiber layer 16, and the fabric layer 19 is disposed on the side of the fabric adhesive layer 18 away from the second nonwoven fabric layer 17.

[0077] To facilitate understanding, the following example illustrates the manufacturing method of the vehicle roof in this embodiment, using a 6mm thick PU board as the substrate 14:

[0078] 1. After spraying adhesive onto the PU board, the adhesive is rolled onto the board via a rolling line to form a first adhesive layer 13 and a second adhesive layer 15. In this embodiment, the frequency of the glue roller motor is set to (38±5) Hz, the frequency of the metering roller motor is set to (28±5) Hz, the height of the glue roller is set to (5.5±0.5) mm, and the angle of the glue roller is set to 40°.

[0079] 2. The adhesive spraying device is controlled to spray molding adhesive separately onto the area corresponding to the second bearing part 102; at the same time, the production line feeds the first non-woven fabric layer 11, glass fiber layer 21, and first glass fiber layer 12. Then, the conveyor belt transports the partially sprayed and fully glued PU board onto the already laid first glass fiber layer 12. Then the production line continues to feed the second glass fiber layer 16 and the second non-woven fabric layer 17.

[0080] 3. After the above materials are laid out, the body to be molded is formed by hot molding. Specifically, the body to be molded is hot molded at a preset temperature and pressure, and the pressure is held for a preset time to allow the body to solidify and form a vehicle roof. In this embodiment, the preset temperature is 120±10°C for the upper mold and 120±10°C for the lower mold, the preset pressure is (100±10) Bar, and the preset time is (20+5) s. The number of venting cycles is set to 1±1 times, and the venting time is approximately 0.4 s, based on the shape of the roof, to prevent the PU sheet from cracking.

[0081] 4. After pressing, the fabric layer is then laminated with the body to be formed. Specifically, the fabric layer 19 is laminated with a set temperature, a set holding time, and a set pressure. In this embodiment, the set temperature is 100±10° for the upper mold and 80±10° for the lower mold, the set pressure is (60±10) Bar, and the set holding time is (28±10) S.

[0082] Compared with related technologies, the embodiments of this application have at least the following advantages: Since the base material portion 1 surrounds the periphery forming the sunroof opening 10 with a first supporting portion 101 and a second supporting portion 102, a first reinforcing layer 21 is formed between the first nonwoven fabric layer 11 and the first glass fiber layer 12 to structurally reinforce the area of ​​the vehicle roof used for installing the sunroof, thus meeting the strength requirements after the removal of the reinforcing frame in this area, thereby ensuring the structural stability of the vehicle roof. Furthermore, compared to a roof with a reinforcing frame, a vehicle roof with a first reinforcing layer 21 formed between adjacent first nonwoven fabric layers 11 and first glass fiber layers 12 is less expensive, lighter, and does not require a separate installation step, simplifying the installation process and improving assembly efficiency.

[0083] Please refer to Figure 4This is a flowchart illustrating a method for manufacturing a vehicle roof according to an embodiment of this application. This embodiment is largely the same as the previous embodiments, with the main difference being that the specific composition of the target material layer and other material layers differs from the previous embodiments; the first reinforcing layer is formed between the first glass fiber layer and the first adhesive layer.

[0084] The specific process of this embodiment is as follows: Figure 4 As shown, it includes the following steps:

[0085] Provide substrate.

[0086] After spraying adhesive onto the top and bottom sides of the substrate, a roll adhesive process is performed to form a first adhesive layer and a second adhesive layer located on the top and bottom sides of the substrate.

[0087] The first nonwoven fabric layer, the first glass fiber layer, and the first reinforcing layer are stacked on the side of the first adhesive layer away from the substrate, and the second glass fiber layer and the second nonwoven fabric layer are stacked on the side of the second adhesive layer away from the substrate to form the body to be molded.

[0088] Specifically, the target material layers in this embodiment include a first adhesive layer 13, a second adhesive layer 15, a second glass fiber layer 16, and a second nonwoven fabric layer 17. Other material layers include a first nonwoven fabric layer 11 and a first glass fiber layer 12. That is, after forming the first adhesive layer 13 and the second adhesive layer 15 on the upper and lower sides of the substrate 14, the second glass fiber layer 16 and the second nonwoven fabric layer 17 are stacked on the side of the substrate 14 where the second adhesive layer 15 is formed. The first reinforcing layer 21 is placed on the side of the substrate 14 where the first adhesive layer 13 is formed. Then, the first nonwoven fabric layer 11 and the first glass fiber layer 21 are stacked on the side of the first reinforcing layer 21 away from the substrate 14 to form the final body to be molded.

[0089] For ease of understanding, the following example will be taken where the first reinforcing layer 21 is disposed on the first supporting part 101 and the first reinforcing layer 21 is a glass fiber layer. Figure 5 and Figure 6 The specific configuration of the first reinforcing layer 21 in this embodiment will be described in detail:

[0090] Please refer to Figure 5 This is another cross-sectional schematic diagram of the first support portion provided in the embodiments of this application. Figure 5 The glass fiber layer 21 shown is disposed between the first glass fiber layer 12 and the first adhesive layer 13.

[0091] Please refer to Figure 6 This is a top view of the vehicle roof provided in an embodiment of this application. Figure 6 The vehicle roof shown is manufactured using the vehicle roof manufacturing method of this embodiment.

[0092] The vehicle roof 100 includes a base material part 1 and a fiberglass layer 21. The base material part 1 is composed of multiple layers of material layers stacked on top of each other. The base material part 1 has a through skylight opening 10; a first bearing part 101 and a second bearing part 102 are formed on the periphery of the base material part 1 surrounding the skylight opening 10. The fiberglass layer 21 is disposed between a first non-woven fabric layer 11 and a first fiberglass layer 12.

[0093] Specifically, in this embodiment, the opposite side surfaces of the first bearing part 101 and the second bearing part 102 are respectively exposed on the opposite side surfaces of the base material part 1. Further, the opposite side surfaces of the first bearing part 101 and the second bearing part 102 are coplanar with the opposite side surfaces of the base material part 1 respectively.

[0094] More specifically, the first bearing part 101 extends along the first direction X, the second bearing part 102 extends along the second direction Y, the length of the first bearing part 101 is greater than the length of the second bearing part 102 and the two intersect. Figure 6 The shown skylight opening 10 is rectangular. The number of the first bearing parts 101 is two, and the two first bearing parts 101 are oppositely arranged on the opposite sides of the long side of the skylight opening 10. The number of the second bearing parts 102 is two, and the two second bearing parts 102 are oppositely arranged at the opposite ends of the short side of the skylight opening 10. The second bearing part 102 is located between the two first bearing parts 101 and the opposite ends are respectively connected to the opposite side surfaces of the first bearing part 101.

[0095] In some embodiments, the number of the first bearing parts 101 can also be one, and the number of the second bearing parts 102 can also be one. This embodiment does not specifically limit the number of the first bearing part 101 and the second bearing part 102.

[0096] Please further refer to Figure 6 , the first bearing part 101 is strip-shaped, its length is greater than the length of the long side of the skylight opening 10 and less than the length of the base material part 1, and its width is less than the width of the base material part 1 on the corresponding side of the long side of the skylight opening 10. The second bearing part 102 is also strip-shaped, its length is equal to the length of the short side of the skylight opening 10, and the opposite ends are respectively connected to one end of the corresponding first bearing part 101. The width of the second bearing part 102 is less than the width of the base material part 1 on one side of the short side of the skylight opening 10. The first bearing part 101 and the second bearing part 102 are connected end to end to form a "mouth" - shaped structure.

[0097] From Figure 6As can be seen, the first support portion 101 and the second support portion 102 are both partial structures of the base material portion 1. By setting this structure, the amount of material used in the glass fiber layer 21 between the two adjacent material layers of the first support portion 101 and / or the second support portion 102 can be reduced, thereby saving the production cost of the vehicle roof 100 while ensuring the structural stability of the vehicle roof 100.

[0098] It is understood that this embodiment does not specifically limit the size of the first support portion 101 and the second support portion 102, and can be set according to actual needs. For example, the first support portion 101 and the second support portion 102 can together form a complete substrate portion 1. When the first reinforcing layer is located on both the first support portion 101 and the second support portion 102, the first reinforcing layer 21 covers the entire substrate portion 1.

[0099] It should be noted that, due to Figure 6 The skylight openings 10 shown are all rectangular, therefore the first direction X is perpendicular to the second direction Y, to ensure that the first support portion 101 and the second support portion 102 are disposed at the periphery of the skylight opening 10. In practical applications, the angle between the first direction Y and the second direction X can be determined according to the actual shape of the skylight opening 10, and this embodiment does not specifically limit this.

[0100] The glass fiber layer 21 in this embodiment can be disposed in various ways, and is not limited to being disposed in the first support portion 101. Figure 6 Taking the vehicle roof 100 shown as an example, the three methods of setting the fiberglass layer 21 are explained in detail:

[0101] Configuration Method 1: A fiberglass layer 21 is disposed on the first support portion 101. The length of the fiberglass layer 21 in the first direction X is the same as the length of the first support portion 101 in the first direction X; the width of the fiberglass layer 21 in the second direction Y is also the same as the width of the first support portion 101 in the second direction Y. This structural configuration enhances the structural strength of the first support portion 101, thereby strengthening the structural strength of the vehicle roof 100.

[0102] Configuration Method Two: A fiberglass layer 21 is disposed on the second support portion 102. The length of the fiberglass layer 21 in the second direction Y is the same as the length of the second support portion 102 in the second direction Y; the width of the fiberglass layer 21 in the first direction X is the same as the width of the second support portion 102 in the first direction X. This configuration enhances the structural strength of the second support portion 102, thereby strengthening the structural strength of the vehicle roof 100.

[0103] Configuration Method 3: A fiberglass layer 21 is simultaneously disposed on both the first support portion 101 and the second support portion 102. The size of the fiberglass layer 21 located on the first support portion 101 is the same as the size of the fiberglass layer 21 separately disposed on the first support portion 101, and the size of the fiberglass layer 21 located on the second support portion 102 is the same as the size of the fiberglass layer 21 separately disposed on the second support portion 102. Further details are omitted here. This structural configuration simultaneously enhances the structural strength of both the first support portion 101 and the second support portion 102, thereby strengthening the structural strength of the vehicle roof 100.

[0104] It is worth mentioning that, from Figure 6 As can be seen, the first support portion 101 is disposed opposite each other along the second direction Y on opposite sides of the long side of the sunroof opening 10, and the second support portion 102 is disposed opposite each other along the first direction X on opposite ends of the short side of the sunroof opening 10, and the area of ​​the first support portion 101 is larger than the area of ​​the second support portion 102. By separately disposing of the glass fiber layer 21 in the first support portion 101, due to the low cost of glass fiber, even if the glass fiber layer 21 is disposed in the larger area of ​​the first support portion 101, it does not require much cost. Thus, while enhancing the structural strength of the vehicle roof 100, the production cost of the vehicle roof 100 can be reduced as much as possible.

[0105] The body to be molded is hot-molded under preset temperature and preset pressure, and the pressure is held for a preset time.

[0106] Compared with related technologies, the embodiments of this application have at least the following advantages: Since the base material portion 1 surrounds the periphery forming the sunroof opening 10, with a first supporting portion 101 and a second supporting portion 102, a first reinforcing layer 21 is formed between the first fiberglass layer 12 and the first adhesive layer 13 to structurally reinforce the area of ​​the vehicle roof used for installing the sunroof, thus meeting the strength requirements after the removal of the reinforcing frame in this area, thereby ensuring the structural stability of the vehicle roof. Furthermore, compared to roofs with reinforcing frames, vehicle roofs with a first reinforcing layer 21 formed between adjacent first fiberglass layers 12 and first adhesive layers 13 are less expensive, lighter, and do not require a separate installation step, simplifying the installation process and improving assembly efficiency.

[0107] Please refer to Figure 7 This is a flowchart illustrating a method for manufacturing a vehicle roof according to an embodiment of this application. This embodiment is largely the same as the previous embodiments, with the main difference being that the specific composition of the target material layer and other material layers differs from the previous embodiments; the first reinforcing layer is formed between the second adhesive layer and the second glass fiber layer.

[0108] The specific process of this embodiment is as follows: Figure 7 As shown, it includes the following steps:

[0109] Provide substrate.

[0110] After spraying adhesive onto the top and bottom sides of the substrate, a roll adhesive process is performed to form a first adhesive layer and a second adhesive layer located on the top and bottom sides of the substrate.

[0111] The first nonwoven fabric layer and the first glass fiber layer are stacked on the side of the first adhesive layer away from the substrate, and the first reinforcing layer, the second glass fiber layer and the second nonwoven fabric layer are stacked on the side of the second adhesive layer away from the substrate to form the body to be molded.

[0112] Specifically, in this embodiment, the target material layer includes a first adhesive layer 13, a second adhesive layer 15, a first nonwoven fabric layer 11, and a first glass fiber layer 12. Other material layers include a second glass fiber layer 16 and a second nonwoven fabric layer 17. That is, after forming the first adhesive layer 13 and the second adhesive layer 15 on the upper and lower sides of the substrate 14, the first nonwoven fabric layer 11 and the first glass fiber layer 12 are stacked on the side of the substrate 14 where the first adhesive layer 13 is formed. The first reinforcing layer 21 is placed on the side of the substrate 14 where the second adhesive layer 15 is formed. Then, the second glass fiber layer 16 and the second nonwoven fabric layer 17 are stacked on the side of the first reinforcing layer 21 away from the substrate 14 to form the final body to be molded.

[0113] Please refer to Figure 8 The first reinforcing layer is a glass fiber layer 21, which is disposed between the second adhesive layer 15 and the second glass fiber layer 16.

[0114] It should be noted that the glass fiber layer 21, disposed between the second adhesive layer 15 and the second glass fiber layer 16, can achieve [the desired effect]. Figure 3 The glass fiber layer 21 shown is disposed between the first nonwoven fabric layer 11 and the first glass fiber layer 12, which has the same technical effect, and will not be described again here to avoid repetition.

[0115] The body to be molded is hot-molded under preset temperature and preset pressure, and the pressure is held for a preset time.

[0116] Compared with related technologies, the embodiments of this application have at least the following advantages: Since the base material portion 1 surrounds the periphery forming the sunroof opening 10, with a first support portion 101 and a second support portion 102, a first reinforcing layer 21 is formed between the second adhesive layer 15 and the second fiberglass layer 16 to structurally reinforce the area of ​​the vehicle roof used for installing the sunroof, thus meeting the strength requirements after the removal of the reinforcing frame in this area, thereby ensuring the structural stability of the vehicle roof. Furthermore, compared to roofs with reinforcing frames, vehicle roofs with a first reinforcing layer 21 formed between adjacent second adhesive layers 15 and second fiberglass layers 16 are less expensive, lighter, and do not require a separate installation step, simplifying the installation process and improving assembly efficiency.

[0117] Please refer to Figure 9 This is a flowchart illustrating a method for manufacturing a vehicle roof according to an embodiment of this application. This embodiment is largely the same as the previous embodiments, with the main difference being that the specific composition of the target material layer and other material layers differs from the previous embodiments; the first reinforcing layer is formed between the second glass fiber layer and the second non-woven fabric layer.

[0118] The specific process of this embodiment is as follows: Figure 9 As shown, it includes the following steps:

[0119] Provide substrate.

[0120] After spraying adhesive onto the top and bottom sides of the substrate, a roll adhesive process is performed to form a first adhesive layer and a second adhesive layer located on the top and bottom sides of the substrate.

[0121] The first nonwoven fabric layer and the first glass fiber layer are stacked on the side of the first adhesive layer away from the substrate, and the second glass fiber layer, the first reinforcing layer and the second nonwoven fabric layer are stacked on the side of the second adhesive layer away from the substrate to form the body to be molded.

[0122] Specifically, the target material layer in this embodiment includes a first adhesive layer 13, a second adhesive layer 15, a first nonwoven fabric layer 11, a first glass fiber layer 12, and a second glass fiber layer 16, while other material layers include a second nonwoven fabric layer 17. That is, after forming the first adhesive layer 13 and the second adhesive layer 15 on the upper and lower sides of the substrate 14, the first nonwoven fabric layer 11 and the first glass fiber layer 12 are stacked on the side of the substrate 14 where the first adhesive layer 13 is formed. The second glass fiber layer 16 is placed on the side of the substrate 14 where the second adhesive layer 15 is formed. Then, the first reinforcing layer 21 is placed on the side of the second glass fiber layer 16 away from the substrate 14. Finally, the second nonwoven fabric layer 17 is placed on the side of the first reinforcing layer 21 away from the substrate 14, forming the final body to be molded.

[0123] Please refer to Figure 10The first reinforcing layer 21 is a glass fiber layer, which is disposed between the second non-woven fabric layer 17 and the second glass fiber layer 16.

[0124] It should be noted that the glass fiber layer 21, disposed between the second nonwoven fabric layer 17 and the second glass fiber layer 16, can achieve the desired effect. Figure 3 The glass fiber layer 21 shown is disposed between the first nonwoven fabric layer 11 and the first glass fiber layer 12, which has the same technical effect, and will not be described again here to avoid repetition.

[0125] The body to be molded is hot-molded under preset temperature and preset pressure, and the pressure is held for a preset time.

[0126] Compared with related technologies, the embodiments of this application have at least the following advantages: The substrate 14 and the multilayer material layers together form the substrate portion 1. Since the substrate portion 1 surrounds the periphery forming the sunroof opening 10, a first support portion 101 and a second support portion 102 are formed. By forming a first reinforcing layer 21 between the second glass fiber layer 16 and the second non-woven fabric layer 17, the area of ​​the vehicle roof used for installing the sunroof is structurally reinforced to meet the strength requirements of this area after the removal of the reinforcing frame, thereby ensuring the structural stability of the vehicle roof. In addition, compared with a roof with a reinforcing frame, the vehicle roof with a first reinforcing layer 21 formed between adjacent second glass fiber layers 16 and second non-woven fabric layers 17 has lower cost, lighter weight, and does not require a separate installation step, simplifying the installation process and improving assembly efficiency.

[0127] Please refer to Figure 11 This is a flowchart illustrating a method for manufacturing a vehicle roof according to an embodiment of this application. This embodiment is a further improvement upon the foregoing embodiments, primarily in that it further includes a second reinforcing layer, which is formed between the first adhesive layer and the first glass fiber layer, and / or between the second glass fiber layer and the second non-woven fabric layer. This method further enhances the structural stability of the vehicle roof.

[0128] The specific process of this embodiment is as follows: Figure 11 As shown, it includes the following steps:

[0129] Provide substrate.

[0130] After spraying adhesive onto the top and bottom sides of the substrate, a roll adhesive process is performed to form a first adhesive layer and a second adhesive layer located on the top and bottom sides of the substrate.

[0131] A second reinforcing layer is formed on the side of the first adhesive layer away from the substrate, and / or a second reinforcing layer is formed on the side of the second adhesive layer away from the substrate.

[0132] In some embodiments, the second reinforcing layer 22 is an adhesive layer.

[0133] In some embodiments, the adhesive layer 22 is made of the same material as the first adhesive layer 13 and the second adhesive layer 15, that is, including but not limited to PA film, PE film or PP film, etc., and the adhesive layer 22 is preferably PA film.

[0134] In some embodiments, the weight per unit area of ​​the adhesive layer 22 is 60 g / m². 2 ~100g / m 2 This embodiment does not specify a particular weight per unit area of ​​the adhesive layer 22, for example, 60 g / m². 2 70g / m 2 80g / m 2 or 90g / m 2 .

[0135] It is worth mentioning that the second reinforcing layer 22 in this embodiment has multiple configuration methods. For example... Figure 6 Taking the vehicle roof 100 shown as an example, the three configuration methods of the second reinforcing layer 22 will be explained in detail:

[0136] Configuration Method 1: A second reinforcing layer 22 is disposed on the first supporting part 101. The length of the second reinforcing layer 22 in the first direction X is the same as the length of the first supporting part 101 in the first direction X; the width of the second reinforcing layer 22 in the second direction Y is also the same as the width of the first supporting part 101 in the second direction Y. With this structure, the structural strength of the first supporting part 101 can be enhanced, thereby enhancing the structural strength of the vehicle roof 100.

[0137] Configuration Method Two: The second reinforcing layer 22 is disposed on the second supporting part 102. The length of the second reinforcing layer 22 in the second direction Y is the same as the length of the second supporting part 102 in the second direction Y; the width of the second reinforcing layer 22 in the first direction X is the same as the width of the second supporting part 102 in the first direction X. With this structure, the structural strength of the second supporting part 102 can be enhanced, thereby enhancing the structural strength of the vehicle roof 100.

[0138] Configuration Method 3: The second reinforcing layer 22 is simultaneously disposed on both the first supporting part 101 and the second supporting part 102. The size of the second reinforcing layer 22 located on the first supporting part 101 is the same as the size of the second reinforcing layer 22 separately disposed on the first supporting part 101, and the size of the second reinforcing layer 22 located on the second supporting part 102 is the same as the size of the second reinforcing layer 22 separately disposed on the second supporting part 102. This configuration enhances the structural strength of both the first supporting part 101 and the second supporting part 102, thereby strengthening the structural strength of the vehicle roof 100.

[0139] It is worth noting that, from Figure 6 As can be seen, the first support portion 101 is disposed opposite each other along the second direction Y on opposite sides of the long side of the sunroof opening 10, and the second support portion 102 is disposed opposite each other along the first direction X on opposite ends of the short side of the sunroof opening 10. That is to say, the area of ​​the first support portion 101 is larger than the area of ​​the second support portion 102. By setting the second reinforcing layer 22 as an adhesive layer and separately disposing of the adhesive layer 22 on the second support portion 102, the high structural strength of the adhesive layer 22 can ensure the structural strength of the relatively small second support portion 102 without excessively increasing the production cost of the vehicle roof 100.

[0140] Please refer to Figure 12 This is a cross-sectional schematic diagram of the second support portion provided in an embodiment of this application. Figure 12 The second reinforcing layer 22 shown is disposed between the first adhesive layer 13 and the first glass fiber layer 12.

[0141] Please refer to Figure 13 This is another cross-sectional schematic diagram of the second support portion provided in the embodiments of this application. Figure 13 The second reinforcing layer 22 shown is disposed between the second adhesive layer 15 and the second glass fiber layer 16.

[0142] The first nonwoven fabric layer and the first glass fiber layer are stacked on the side of the first adhesive layer away from the substrate, and the second glass fiber layer, the first reinforcing layer and the second nonwoven fabric layer are stacked on the side of the second adhesive layer away from the substrate to form the body to be molded.

[0143] The body to be molded is hot-molded under preset temperature and preset pressure, and the pressure is held for a preset time.

[0144] Compared with related technologies, the embodiments of this application have at least the following advantages: the substrate 14 and the multilayer material layer together form the substrate part 1. Since the substrate part 1 surrounds the periphery of the sunroof opening 10 and forms the first support part 101 and the second support part 102, the second reinforcing layer 22 is formed in the first support part 101 and / or the second support part 102 to structurally reinforce the area of ​​the vehicle roof used for installing the sunroof, so as to meet the strength requirements of the area after the reinforcing frame is removed, thereby ensuring the structural stability of the vehicle roof.

[0145] Please refer to Figure 14 This is a flowchart illustrating a method for manufacturing a vehicle roof according to an embodiment of this application. This embodiment is a further improvement upon the aforementioned embodiments, primarily in that a reinforcing adhesive layer is formed on the same material layer as the first support portion and the substrate 14, or on the same material layer as the first support portion and the second adhesive layer. This method further enhances the structural stability of the vehicle roof.

[0146] The specific process of this embodiment is as follows: Figure 14 As shown, it includes the following steps:

[0147] Provide substrate.

[0148] After spraying adhesive onto the top and bottom sides of the substrate, a roll adhesive process is performed to form a first adhesive layer and a second adhesive layer located on the top and bottom sides of the substrate.

[0149] A reinforcing adhesive layer is formed on the same material layer as the first carrier portion and the substrate.

[0150] Specifically, after the reinforcing adhesive layer 20 is formed on the first support portion 101, the reinforcing adhesive layer 20 is located on the side of the second adhesive layer 15 near the substrate 14.

[0151] In some embodiments, a reinforcing adhesive layer 20 may also be formed on a material layer that is the same as the first support portion 101 and the second adhesive layer 15. That is, the reinforcing adhesive layer 20 is located on the side of the second adhesive layer 15 away from the substrate 14.

[0152] To facilitate understanding, the following will be combined with... Figure 15 The function of the reinforcing adhesive layer in this embodiment will be explained in detail below:

[0153] like Figure 15 As shown, since the fabric layer 19 is disposed adjacent to the second adhesive layer 15, the weight per unit area of ​​the second adhesive layer 15 is set to be relatively low to prevent the fabric layer 19 from permeating through the adhesive. Furthermore, since the adhesive strength of the second adhesive layer 15 may be insufficient to stably bond the glass fiber layer 21 after the glass fiber layer 21 is disposed between the second adhesive layer 15 and the second glass fiber layer 16, this embodiment ensures the structural stability of the first load-bearing portion 101 after the glass fiber layer 21 is disposed between the second adhesive layer 15 and the second glass fiber layer 16 by providing a reinforcing adhesive layer 20, thereby ensuring the structural stability of the vehicle roof 100.

[0154] Understandable Figure 15 The reinforcing adhesive layer 20 shown is disposed between the substrate 14 and the second adhesive layer 15. In practical applications, the reinforcing adhesive layer 20 can also be disposed between the second adhesive layer 15 and the second glass fiber layer 16 to achieve the same technical effect.

[0155] In some embodiments, the second adhesive layer 15 is integrally formed with the reinforcing adhesive layer 20. That is, during the process of spray-molding the second adhesive layer 15, the weight per unit area of ​​the second adhesive layer 15 can be increased, such as... Figure 10 As shown, the increased thickness of the second adhesive layer 15 eliminates the need for additional molding of the reinforcing adhesive layer 20. The second adhesive layer 15 alone can achieve the bonding of the second fiberglass layer 16 and the fiberglass layer 21, thereby improving the production efficiency of the vehicle roof 100.

[0156] A second reinforcing layer is formed on the side of the first adhesive layer away from the substrate, and / or a second reinforcing layer is formed on the side of the second adhesive layer away from the substrate.

[0157] The first nonwoven fabric layer and the first glass fiber layer are stacked on the side of the first adhesive layer away from the substrate, and the second glass fiber layer, the first reinforcing layer and the second nonwoven fabric layer are stacked on the side of the second adhesive layer away from the substrate to form the body to be molded.

[0158] The body to be molded is hot-molded under preset temperature and preset pressure, and the pressure is held for a preset time.

[0159] Compared with related technologies, the embodiments of this application have at least the following advantages: the substrate 14 and the multilayer material layers together form the substrate part 1. Since the substrate part 1 surrounds the periphery forming the sunroof opening 10, the first support part 101 and the second support part 102 are formed. By providing the reinforcing adhesive layer 20, the structural stability of the first support part 101 can be ensured after the glass fiber layer 21 is placed between the second adhesive layer 15 and the second glass fiber layer 16, thereby ensuring the structural stability of the vehicle roof 100.

[0160] This application also provides a vehicle roof manufactured using any of the above-described methods.

[0161] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application.
