Description

Technical Field

[0001] The present application relates to the technical field of composite panels, and in particular to a vehicle roof and a vehicle. Background Art

[0002] With the development of automobile technology and the expansion of functions, as well as the improvement of people's living standards, the proportion of large sunroofs and panoramic sunroofs has increased. The mainstream production process of vehicle roofs today is the molding method of PU substrate plus fabric. Due to the large opening of the sunroof hole, it is necessary to add a sunroof reinforcement frame on the back of the roof body to meet the requirements of the strength and contour of the roof sunroof.

[0003] In the related art, the reinforcement frame is a metal reinforcement frame or a plastic reinforcement frame. However, the metal reinforcement frame will increase the weight of the vehicle roof, and the mold cost of the plastic reinforcement frame is high, which leads to a high production cost of the vehicle roof.

[0033] Please refer to Figures 1 to 4 , Figure 1 A top view of a vehicle roof provided in an embodiment of the present application, Figure 2 Another top view of the vehicle roof provided in an embodiment of the present application, Figure 3 Another top view of the vehicle roof provided in the embodiment of the present application, Figure 4 A cross-sectional schematic diagram of the first bearing portion provided in an embodiment of the present application.

[0034] The vehicle roof 100 includes a base material portion 1 and a reinforcement portion. The base material portion 1 is composed of a plurality of stacked material layers, and a skylight opening 10 is provided through the base material portion 1. The base material portion 1 is provided with a first bearing portion 101 and a second bearing portion 102 around the periphery of the skylight opening 10, and the reinforcement portion is provided between two adjacent material layers of the first bearing portion 101 and / or the second bearing portion 102.

[0035] Compared with the related art, the embodiment of the present application has at least the following advantages: since the substrate part 1 is provided with a first bearing part 101 and a second bearing part 102 around the periphery of the skylight opening 10, a reinforcement part is added between two adjacent material layers of the first bearing part 101 and / or the second bearing part 102 to structurally reinforce the area of ​​the vehicle roof 100 for installing the skylight, so as to meet the strength requirements of the area after the reinforcement frame is removed, thereby ensuring the structural stability of the vehicle roof 100. In addition, compared with a roof with a reinforcement frame, a vehicle roof with a reinforcement part added between two adjacent material layers has lower cost, lighter weight, and does not require a separate installation step, which simplifies the installation process and improves assembly efficiency.

[0036] Specifically, the opposite side surfaces of the first supporting portion 101 and the second supporting portion 102 in this embodiment are respectively exposed to the opposite side surfaces of the substrate portion 1. Furthermore, the opposite side surfaces of the first supporting portion 101 and the second supporting portion 102 are respectively coplanar with the opposite side surfaces of the substrate portion 1.

[0037] More specifically, the first bearing portion 101 is extended along the first direction X, and the second bearing portion 102 is extended along the second direction Y. The length of the first bearing portion 101 is greater than that of the second bearing portion 102 and the first bearing portion 101 and the second bearing portion 102 are intersectingly disposed. Figures 1 to 3 The skylight openings 10 shown are all rectangular in shape. There are two first bearing parts 101, which are relatively arranged at two opposite sides of the long side of the skylight opening 10, and there are two second bearing parts 102, which are relatively arranged at two 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 of the second bearing part 102 are respectively connected to the opposite two side surfaces of the first bearing part 101.

[0038] In some embodiments, the number of the first bearing portion 101 may be one, and the number of the second bearing portion 102 may be one. This embodiment does not specifically limit the number of the first bearing portion 101 and the second bearing portion 102 .

[0039] Please read further Figure 1 The first bearing portion 101 is in a strip shape, and its length is greater than the length of the long side of the skylight opening 10 and less than the length of the substrate portion 1, and its width is less than the width of the substrate portion 1 on the side corresponding to the long side of the skylight opening 10. The second bearing portion 102 is also in a strip shape, and 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 portion 101, and the width of the second bearing portion 102 is less than the width of the substrate portion 1 on the side of the short side of the skylight opening 10. The first bearing portion 101 and the second bearing portion 102 are connected at the first position to form a "mouth"-shaped structure.

[0040] from Figure 1 It can be seen that the first bearing part 101 and the second bearing part 102 are both local structures of the base material part 1. Through the arrangement of such a structure, the material usage of the reinforcement part arranged between two adjacent material layers of the first bearing part 101 and / or the second bearing part 102 can be reduced, thereby ensuring the structural stability of the vehicle roof 100 while saving the production cost of the vehicle roof 100.

[0041] Please read further Figure 2 The vehicle roof 200 in this embodiment is similar to the vehicle roof 100, except that: Figure 2 The length of the first supporting portion 101a shown is greater than the length of the long side of the skylight opening 10 and is the same as the length of the substrate portion 1a, and its width is less than the width of the substrate portion 1a on the side corresponding to the long side of the skylight opening 10. The length of the second supporting portion 102a is equal to the length of the short side of the skylight opening 10, and the opposite ends are respectively connected to the corresponding inner surfaces of the first supporting portion 101a. The first supporting portion 101a and the second supporting portion 102a are connected to form a "well"-shaped structure.

[0042] Since the length of the first bearing portion 101a is equal to the length of the base material portion 1a, when the reinforcement portion is disposed between two adjacent material layers of the first bearing portion 101a, the reinforcement portion can be directly formed by the original manufacturing equipment for producing the vehicle roof 200, so as to facilitate the assembly line production of the vehicle roof 200 and reduce the manufacturing difficulty of the vehicle roof 200. In addition, the first bearing portion 101a and the second bearing portion 102a are both local structures of the base material portion 1, which can reduce the material usage of the reinforcement portion disposed between two adjacent material layers of the first bearing portion 101a and / or the second bearing portion 102a, thereby saving the production cost of the vehicle roof 100.

[0043] Please participate further Figure 3 The vehicle roof 300 of this embodiment is similar to the vehicle roof 100, except that: the substrate portions 1b on the two opposite sides of the long side of the skylight opening 10 form the first bearing portion 101b, and the substrate portions 1b on the two opposite sides of the short side of the skylight opening 10 form the second bearing portion 102b. In other words, the length of the first bearing portion 101b is greater than the length of the long side of the skylight opening 10 and is the same as the length of the substrate portion 1b, and its width is equal to the width of the substrate portion 1b on the side corresponding to the long side of the skylight opening 10; the length of the second bearing portion 102b is equal to the length of the short side of the skylight opening 10, and its width is equal to the width of the substrate portion 1b on the side of the short side of the skylight opening 10.

[0044] By setting such a structure, the structural stability of the vehicle roof 300 can be improved while the difficulty of manufacturing the vehicle roof 300 can be further reduced.

[0045] It is understandable that due to Figures 1 to 3 The skylight openings 10 shown are all rectangular, so the first direction X is perpendicular to the second direction Y to ensure that the first supporting portion 101 and the second supporting portion 102 are arranged 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.

[0046] Please see further Figure 4 The base material portion 1 includes a first nonwoven fabric layer 11 , a first glass fiber layer 12 , a first adhesive layer 13 , a base plate 14 , a second adhesive layer 15 , a second glass fiber layer 16 and a second nonwoven fabric layer 17 which are stacked.

[0047] For ease of understanding, the following describes in detail the film layer structures included in the substrate portion 1:

[0048] The first non-woven fabric layer 11 and the second non-woven fabric layer 17 are both made of polyester fibers or polyester fibers. Non-woven fabric is a fabric that does not require spinning or weaving. It is simply a fabric that is made by directional or random arrangement of textile staple fibers or filaments to form a fiber mesh structure, which is then reinforced by mechanical, thermal bonding or chemical methods.

[0049] In some embodiments, the weight per unit area of ​​the first non-woven fabric layer 11 and the second non-woven fabric layer 17 is 45 g / m 2 ~80g / m 2 The present embodiment does not specifically limit the unit area weight of the first non-woven fabric layer 11 and the second non-woven fabric layer 17, for example, 50 g / m 2 , 55g / m 2 , 60g / m 2 or 70g / m 2 .

[0050] It is understandable that, in the same vehicle roof 100, the weight per unit area of ​​the first non-woven fabric layer 11 and the second non-woven fabric layer 17 may be the same or different, and may be set according to actual needs.

[0051] The first glass fiber layer 12 and the second glass fiber layer 16 are both layered structures composed of glass fibers. The glass fibers are preferably alkali-free glass fibers or medium-alkali glass fibers with a length of 10-100 mm.

[0052] 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 / m 2 ~220g / m 2 The present embodiment does not specifically limit the weight per unit area of ​​the first glass fiber layer 12 and the second glass fiber layer 16, for example, 130 g / m 2 , 140g / m 2 , 160g / m 2 or 180g / m 2 .

[0053] It is understandable that, in the same vehicle roof 100 , the weight per unit area of ​​the first glass fiber layer 12 and the second glass fiber layer 16 may be the same or different, and may be set according to actual needs.

[0054] The first adhesive layer 13 and the second adhesive layer 15 play a bonding role. The materials of the first adhesive layer 13 and the second adhesive layer 15 include but are not limited to PA film, PE film or PP film, etc. The adhesive layer is preferably a PA film.

[0055] In some embodiments, the weight per unit area of ​​the first adhesive layer 13 is 130 g / m 2 ~260g / m 2 The present embodiment does not specifically limit the weight per unit area of ​​the first adhesive layer 13, for example, 130 g / m 2 , 160g / m 2 , 180g / m 2 or 220g / m 2 .

[0056] In some embodiments, the second adhesive layer 15 has a unit area weight of 100 g / m 2 ~240g / m 2 The present embodiment does not specifically limit the weight per unit area of ​​the second adhesive layer 15, for example, 110 g / m 2 , 160g / m 2 , 180g / m 2 or 220g / m 2 .

[0057] The substrate 14 is a PU (Polyurethane) board or a PET (Polyethylene terephthalate) board, and the thickness of the substrate 14 is 4 mm to 10 mm, for example, 4 mm, 5 mm, 6 mm, 8 mm or 10 mm.

[0058] In some embodiments, the density of the substrate 14 is 20 kg / m 3 ~30kg / m 3 The density of the substrate 14 is not specifically limited in this embodiment, for example, 23 kg / m 3 , 24kg / m 3 , 25kg / m 3 or 26kg / m 3 .

[0059] Please see further Figure 4 The reinforcement part includes a glass fiber layer 21 , and the glass fiber layer 21 is arranged between the first non-woven fabric layer 11 and the first glass fiber layer 12 .

[0060] by Figure 1 Taking the vehicle roof 100 as an example, three configurations of the glass fiber layer 21 are specifically described:

[0061] In some embodiments, the glass fiber layer 21 is disposed on the first load-bearing portion 101. The length of the glass fiber layer 21 in the first direction X is the same as the length of the first load-bearing portion 101 in the first direction X; the width of the glass fiber layer 21 in the second direction Y is also the same as the width of the first load-bearing portion 101 in the second direction Y. By setting such a structure, the structural strength of the first load-bearing portion 101 can be enhanced, thereby enhancing the structural strength of the vehicle roof 100.

[0062] In some embodiments, the glass fiber layer 21 is disposed on the second load-bearing portion 102. The length of the glass fiber layer 21 in the second direction Y is the same as the length of the second load-bearing portion 102 in the second direction Y; the width of the glass fiber layer 21 in the first direction X is the same as the width of the second load-bearing portion 102 in the first direction X. By setting such a structure, the structural strength of the second load-bearing portion 102 can be enhanced, thereby enhancing the structural strength of the vehicle roof 100.

[0063] It can be understood that in some embodiments, the glass fiber layer 21 can be simultaneously disposed on the first load-bearing portion 101 and the second load-bearing portion 102. The size of the glass fiber layer 21 located on the first load-bearing portion 101 is the same as the size of the glass fiber layer 21 disposed solely on the first load-bearing portion 101, and the size of the glass fiber layer 21 located on the second load-bearing portion 102 is the same as the size of the glass fiber layer 21 disposed solely on the second load-bearing portion 102, which will not be described in detail herein. By setting such a structure, the structural strength of the first load-bearing portion 101 and the second load-bearing portion 102 can be simultaneously enhanced, thereby enhancing the structural strength of the vehicle roof 100.

[0064] It is worth noting that from Figure 1 It can be seen that the first bearing portion 101 is relatively arranged at two opposite sides of the long side of the sunroof opening 10 along the second direction Y, and the second bearing portion 102 is relatively arranged at two opposite ends of the short side of the sunroof opening 10 along the first direction X, and the area of ​​the first bearing portion 101 is larger than the area of ​​the second bearing portion 102. By arranging the glass fiber layer 21 separately on the first bearing portion 101, due to the low cost of glass fiber, even if the glass fiber layer 21 is arranged on the first bearing portion 101 with a larger area, it does not cost much, so that the production cost of the vehicle roof 100 can be reduced as much as possible while enhancing the structural strength of the vehicle roof 100.

[0065] In some embodiments, the weight per unit area of ​​the glass fiber layer 21 is 130 g / m 2 ~150g / m 2 The present embodiment does not specifically limit the weight per unit area of ​​the glass fiber layer 21, for example, 130 g / m 2 , 135g / m 2 , 140g / m 2 or 145g / m 2 .

[0066] In some embodiments, 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 vehicle roof 100 can be further lightweight while improving the structural strength of the vehicle roof 100.

[0067] Combine the following Figures 5 to 8 , other arrangement positions of the glass fiber layer 21 in the first bearing portion 101 are specifically described:

[0068] Please refer to Figure 5 , is another cross-sectional schematic diagram of the first supporting portion 101 provided in an embodiment of the present application. Figure 5 The glass fiber layer 21 is shown disposed between the first glass fiber layer 12 and the first bonding layer 13 .

[0069] It should be noted that the glass fiber layer 21 is disposed between the first glass fiber layer 12 and the first bonding layer 13 to achieve Figure 4 The first reinforcement part 1 shown is arranged between the first non-woven fabric layer 11 and the first glass fiber layer 12 , and has the same technical effect. In order to avoid repetition, it will not be described again here.

[0070] Please refer to Figure 6 , is another cross-sectional schematic diagram of the first bearing portion 101 provided in an embodiment of the present application. Figure 6 The glass fiber layer 21 is shown disposed between the second bonding layer 15 and the second glass fiber layer 16 .

[0071] It should be noted that Figure 6 The first bearing portion 101 shown can achieve the same Figure 4 The same technical effects as those of the first supporting portion 101 shown are not described again here to avoid repetition.

[0072] Please refer to further Figure 6 The substrate part 1 also includes a fabric adhesive layer 18 and a fabric layer 19; the fabric adhesive layer 18 is arranged on the side of the second non-woven fabric layer 17 away from the second glass fiber layer 16, and the fabric layer 19 is arranged on the side of the fabric adhesive layer 18 away from the second non-woven fabric layer 17; it also includes a reinforcing adhesive layer 20, which is arranged between the substrate 14 and the second adhesive layer 15.

[0073] In some embodiments, the fabric adhesive layer 18 is a composite adhesive, and the weight per unit area of ​​the fabric adhesive layer 18 is 16 g / m 2 ~80g / m 2 The present embodiment does not specifically limit the unit area weight of the fabric adhesive layer 18, for example, 20 g / m 2 , 30g / m 2 , 40g / m 2 or 50g / m 2 .

[0074] It is worth mentioning that, since the fabric layer 19 is disposed adjacent to the second adhesive layer 15, the weight per unit area of ​​the second adhesive layer 19 is set relatively low in order to prevent the fabric layer 19 from leaking adhesive. Since, after the glass fiber layer 21 is disposed between the second adhesive layer 15 and the second glass fiber layer 16, the viscosity of the second adhesive layer 15 may be difficult to stably bond the glass fiber layer 21, the present embodiment, by providing the reinforcing adhesive layer 20, can ensure the structural stability of the first bearing portion 101 after the glass fiber layer 21 is disposed between the second adhesive layer 15 and the second glass fiber layer 16, thereby ensuring the structural stability of the vehicle roof 100.

[0075] Understandably, Figure 6The 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 may also be disposed between the second adhesive layer 15 and the second glass fiber layer 16 to achieve the same technical effect.

[0076] In some embodiments, the second adhesive layer 15 is integrally formed with the reinforcing adhesive layer 20. That is, in the process of spraying the second adhesive layer 15, the unit area weight of the second adhesive layer 15 can be increased, such as Figure 7 As shown, the thickness of the second adhesive layer 15 is increased, and no additional process is required to form the reinforcing adhesive layer 20 . The second adhesive layer 15 alone can achieve the bonding of the second glass fiber layer 16 and the glass fiber layer 21 , thereby improving the production efficiency of the vehicle roof 100 .

[0077] It should be noted that Figure 7 The first bearing portion 101 shown can achieve the same Figure 6 The same technical effects as those of the first supporting portion 101 shown are not described again here to avoid repetition.

[0078] Please refer to Figure 8 , is another cross-sectional schematic diagram of the first bearing portion 101 provided in an embodiment of the present application. Figure 8 The glass fiber layer 21 shown is arranged between the second glass fiber layer 16 and the second nonwoven fabric layer 17 .

[0079] It should be noted that Figure 8 The first bearing portion 101 shown can achieve the same Figure 6 The same technical effects as those of the first supporting portion 101 shown are not described again here to avoid repetition.

[0080] Please refer to Fig. 9 , is a cross-sectional schematic diagram of the second bearing portion 102 provided in an embodiment of the present application. The reinforcing portion further includes an adhesive layer 22 , and the adhesive layer 22 is disposed between the first adhesive layer 13 and the substrate 14 .

[0081] by Figure 1 Taking the vehicle ceiling 100 as an example, three configuration methods of the adhesive layer 22 are specifically described:

[0082] In some embodiments, the adhesive layer 22 is disposed on the first supporting portion 101. The length of the adhesive layer 22 in the first direction X is the same as the length of the first supporting portion 101 in the first direction X; the width of the adhesive layer 22 in the second direction Y is also the same as the width of the first supporting portion 101 in the second direction Y. By setting such a structure, the structural strength of the first supporting portion 101 can be enhanced, thereby enhancing the structural strength of the vehicle roof 100.

[0083] In some embodiments, the adhesive layer 22 is disposed on the second supporting portion 102. The length of the adhesive layer 22 in the second direction Y is the same as the length of the second supporting portion 102 in the second direction Y; the width of the adhesive layer 22 in the first direction X is the same as the width of the second supporting portion 102 in the first direction X. By setting such a structure, the structural strength of the second supporting portion 102 can be enhanced, thereby enhancing the structural strength of the vehicle roof 100.

[0084] In some embodiments, the adhesive layer 22 is disposed on both the first supporting portion 101 and the second supporting portion 102. The size of the adhesive layer 22 located on the first supporting portion 101 is the same as the size of the adhesive layer 22 disposed solely on the first supporting portion 101, and the size of the adhesive layer 22 located on the second supporting portion 102 is the same as the size of the adhesive layer 22 disposed solely on the second supporting portion 102, which will not be described in detail herein. By setting such a structure, the structural strength of the first supporting portion 101 and the second supporting portion 102 can be enhanced at the same time, thereby enhancing the structural strength of the vehicle roof 100.

[0085] It is worth noting that from Figure 1 It can be seen that the first bearing portion 101 is relatively arranged at two opposite sides of the long side of the sunroof opening 10 along the second direction Y, and the second bearing portion 102 is relatively arranged at two opposite ends of the short side of the sunroof opening 10 along the first direction X, that is, the area of ​​the first bearing portion 101 is larger than the area of ​​the second bearing portion 102. By separately arranging the adhesive layer 22 on the second bearing portion 102, the structural strength of the adhesive layer 22 is relatively high, so that the structural strength of the second bearing portion 102 with a smaller area can be ensured, and the production cost of the vehicle roof 100 will not be excessively increased.

[0086] Please refer to Fig.10 , is another cross-sectional schematic diagram of the second supporting portion 102 provided in an embodiment of the present application. Fig.10 The adhesive layer 22 is shown to be disposed between the substrate 14 and the second bonding layer 15 .

[0087] It should be noted that Fig.10 The second bearing portion 102 shown can achieve the same Fig. 9 The same technical effects as those of the second supporting portion 102 are shown, and are not described again here to avoid repetition.

[0088] Please refer to Figures 4 to 10In the present application, the glass fiber layer 21 is preferably disposed on the first load-bearing portion 101, and the adhesive layer 22 is disposed on the second load-bearing portion 102. Since the area of ​​the first load-bearing portion 101 is larger than that of the second load-bearing portion 102, and since the cost of glass fiber is relatively low, and the structural strength of the adhesive layer 22 is relatively high, such a structural arrangement can ensure the structural strength of the first load-bearing portion 101 and the second load-bearing portion 102 while reducing the production cost of the vehicle roof 100 as much as possible.

[0089] It is worth mentioning that the overall gram weight of the substrate part 1, which is composed of the first non-woven fabric layer 11, the first glass fiber layer 12, the first adhesive layer 13, the base plate 14, the second adhesive layer 15, the second glass fiber layer 16 and the second non-woven fabric layer 17, is consistent with 850 g / m 2 The total weight of the reinforcement part can be greater than or equal to 200g / m 2 The reinforcement part is pressed together with the base material part 1 in the mold of the vehicle roof 100, that is, the gram weight of the reinforcement area satisfies ≥1050g / m 2 , so the strength requirement of the region can be met. In addition, the material selected for the reinforcement part in this embodiment is still the same as part of the material of the base material part 1, and no other types of materials are added, so no additional procurement process is added.

[0090] Taking the case where the reinforcement portion includes a glass fiber layer 21 disposed on the first bearing portion 101 and an adhesive layer 22 disposed on the second bearing portion 102 as an example, the gram weight of each film layer in this embodiment is specifically described by way of example:

[0091] Specifically, the glass fiber layer 21 is disposed between the first non-woven fabric layer 11 and the first glass fiber layer 12, or between the first glass fiber layer 12 and the first adhesive layer 13; the adhesive layer 22 is disposed between the substrate 14 and the second adhesive layer 15. The unit area weight of the first non-woven fabric layer 11 is 60 g / m 2 , the unit area weight of the glass fiber layer 21 is 130 g / m 2 The weight per unit area of ​​the first glass fiber layer 12 is 200 g / m 2 The first adhesive layer 13 has a unit area weight of 130 g / m 2 The substrate 14 is a 6 mm thick PU sheet with a density of 23 kg / m 3 , the unit area weight of the adhesive layer 22 is 70g / m 2 The second adhesive layer 15 has a unit area weight of 110 g / m 2 The weight per unit area of ​​the second glass fiber layer 16 is 130 g / m 2 The second nonwoven fabric layer 17 has a unit area weight of 55 g / m 2, the unit area weight of the fabric adhesive layer 18 is 20g / m 2 The vehicle roof 100 formed in this way has a grammage of 850 g / m2 in the area of ​​the substrate 1 except the first load-bearing part 101 and the second load-bearing part 102. 2 The gram weight of the first bearing portion 101 area is 980g / m 2 The gram weight of the second bearing portion 102 area is 920 g / m 2 .

[0092] It is understandable that in Figure 2 and Figure 3 In the vehicle roof shown in FIG. 1 , the arrangement method and the arrangement position of the reinforcement part are the same as those in the aforementioned Figure 1 The vehicle roofs shown are the same and can achieve the same technical effects, so they will not be described here in order to avoid repetition.

[0093] The above description is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application.
