For easy understanding, the following specifically exemplifies a method for manufacturing a vehicle ceiling according to the present embodiment, taking a PU board with a 6mm substrate 14 as an example:
1. After the PU plate is sprayed with glue, glue is rolled through a glue rolling line to form a first bonding layer 13 and a second bonding layer 15. In this example, the rubber roll motor frequency was set to (38.+ -. 5) HZ, the metering roll motor frequency was set to (28.+ -. 5) HZ, the rubber roll height was set to (5.5.+ -. 0.5) mm, and the rubber roll was set to 40 °.

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, and the other material layers include a first nonwoven fabric layer 11 and a first glass fiber layer 12. That is, after the first adhesive layer 13 and the second adhesive layer 15 are formed on the upper and lower sides of the substrate 14, the second glass fiber layer 16 and the second non-woven 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, and then the first non-woven 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, so as to form the final body to be formed.
For easy understanding, the following describes the manner of disposing the first reinforcing layer 21 in the present embodiment with reference to fig. 5 and 6, taking the first reinforcing layer 21 disposed on the first carrying portion 101 as an example, and the first reinforcing layer 21 is a glass fiber layer.
Fig. 5 is a schematic cross-sectional view of a first carrier according to an embodiment of the application. The glass fiber layer 21 shown in fig. 5 is disposed between the first glass fiber layer 12 and the first adhesive layer 13.
Fig. 6 is a top view of a vehicle roof according to an embodiment of the application. The vehicle roof shown in fig. 6 is manufactured by the manufacturing method of the vehicle roof of the present embodiment.
The vehicle roof 100 includes a base material portion 1 and a glass fiber layer 21, the base material portion 1 is composed of a plurality of material layers stacked one on another, and the base material portion 1 is provided with a sunroof opening 10 penetrating therethrough; the first and second carrying portions 101 and 102 are formed around the periphery of the skylight opening 10 of the base material portion 1, and the glass fiber layer 21 is disposed between the first nonwoven fabric layer 11 and the first glass fiber layer 12.
Specifically, opposite side surfaces of the first carrying portion 101 and the second carrying portion 102 in the present embodiment are exposed on opposite side surfaces of the substrate portion 1. Further, the opposite side surfaces of the first bearing portion 101 and the second bearing portion 102 are coplanar with the opposite side surfaces of the substrate portion 1.
More specifically, the first bearing portion 101 is formed by extending along the first direction X, the second bearing portion 102 is formed by extending along the second direction Y, and the length of the first bearing portion 101 is greater than that of the second bearing portion 102 and the first bearing portion and the second bearing portion are intersected. The sunroof opening 10 shown in fig. 6 is rectangular in configuration. The number of the first bearing parts 101 is two, the two first bearing parts 101 are oppositely arranged at two opposite sides of the long side of the skylight opening 10, the number of the second bearing parts 102 is two, the two second bearing parts 102 are oppositely arranged at two opposite ends of the short side of the skylight opening 10, the second bearing parts 102 are positioned between the two first bearing parts 101, and the two opposite ends are respectively connected with two opposite side surfaces of the first bearing parts 101.
In some embodiments, the number of the first bearing portions 101 may be one, and the number of the second bearing portions 102 may be one, which is not specifically limited in this embodiment.
Referring to fig. 6, the first carrying portion 101 is in a strip shape, and has a length greater than the length of the long side of the skylight opening 10 and smaller than the length of the base material portion 1, and a width smaller than the width of the base material portion 1 corresponding to the long side of the skylight opening 10. The second carrying portion 102 is also in a strip shape, the length of the second carrying portion is equal to the length of the short side of the skylight opening 10, and the opposite ends of the second carrying portion 102 are respectively connected with one end of the corresponding first carrying portion 101, and the width of the second carrying portion 102 is smaller than the width of the substrate portion 1 on the short side of the skylight opening 10. The first bearing portion 101 and the second bearing portion 102 are connected end to form a "mouth" structure.
As can be seen from fig. 6, the first bearing portion 101 and the second bearing portion 102 are both partial structures of the base material portion 1, and by the arrangement of such structures, the material amount of the glass fiber layer 21 disposed between two adjacent material layers of the first bearing portion 101 and/or the second bearing portion 102 can be reduced, so that the production cost of the vehicle roof 100 can be saved while the structural stability of the vehicle roof 100 is ensured.
It is to be understood that the size of the first bearing portion 101 and the second bearing portion 102 is not specifically limited in this embodiment, and may be set according to actual requirements. For example, the first bearing portion 101 and the second bearing portion 102 may together form the complete substrate portion 1, and when the first reinforcing layer is located at both the first bearing portion 101 and the second bearing portion 102, the first reinforcing layer 21 covers the entire substrate portion 1.
Since the sunroof opening 10 shown in fig. 6 is rectangular, the first direction X is perpendicular to the second direction Y to ensure that the first and second bearing portions 101 and 102 are disposed at the periphery of the sunroof opening 10. In practical applications, the angle between the first direction Y and the second direction X may be determined according to the actual shape of the sunroof opening 10, which is not particularly limited in this embodiment.
The glass fiber layer 21 of the present embodiment has various arrangement modes, and is not limited to being arranged on the first carrying portion 101. Taking the vehicle ceiling 100 shown in fig. 6 as an example, three arrangement modes of the glass fiber layer 21 will be specifically described:
Setting mode one: the glass fiber layer 21 is provided on the first carrying portion 101. The length of the glass fiber layer 21 in the first direction X is the same as the length of the first 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 bearing portion 101 in the second direction Y. By such a structural arrangement, the structural strength of the first bearing portion 101 can be enhanced, thereby enhancing the structural strength of the vehicle roof 100.
Setting mode II: the glass fiber layer 21 is disposed on the second carrying portion 102. The length of the glass fiber layer 21 in the second direction Y is the same as the length of the second 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 bearing portion 102 in the first direction X. By such a structural arrangement, the structural strength of the second bearing portion 102 can be enhanced, thereby enhancing the structural strength of the vehicle roof 100.
Setting mode III: the glass fiber layer 21 is simultaneously disposed on the first bearing portion 101 and the second bearing portion 102, the size of the glass fiber layer 21 disposed on the first bearing portion 101 is the same as the size of the glass fiber layer 21 separately disposed on the first bearing portion 101, and the size of the glass fiber layer 21 disposed on the second bearing portion 102 is the same as the size of the glass fiber layer 21 separately disposed on the second bearing portion 102, which is not repeated herein. By such a structural arrangement, the structural strength of the first and second load bearing portions 101 and 102 can be simultaneously enhanced, thereby enhancing the structural strength of the vehicle roof 100.
It should be noted that, as can be seen from fig. 6, the first bearing portion 101 is disposed opposite to the long side of the skylight opening 10 along the second direction Y, the second bearing portion 102 is disposed opposite to the short side of the skylight 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 providing the glass fiber layer 21 alone to the first bearing portion 101, it is unnecessary to spend a lot of costs even if the glass fiber layer 21 is provided to the first bearing portion 101 having a large area because of low cost of glass fibers, so that it is possible to reduce the production cost of the vehicle roof 100 as much as possible while enhancing the structural strength of the vehicle roof 100.
And carrying out hot mould pressing on the body to be formed at a preset temperature and a preset pressure, and maintaining the pressure for a preset time.

In addition, compared to the framed roof, the vehicle roof in which the first reinforcing layer 21 is formed between the adjacent first glass fiber layer 12 and first adhesive layer 13 is lower in cost, lighter in weight, and does not require a separate mounting step, simplifying the mounting process, and improving the assembly efficiency.

It should be noted that the second reinforcing layer 22 of the present embodiment has a plurality of arrangements. Taking the vehicle ceiling 100 shown in fig. 6 as an example, three modes of disposing the second reinforcing layer 22 will be specifically described:
Setting mode one: the second reinforcing layer 22 is disposed on the first bearing portion 101. The length of the second reinforcing layer 22 in the first direction X is the same as the length of the first bearing portion 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 bearing portion 101 in the second direction Y. By such a structural arrangement, the structural strength of the first bearing portion 101 can be enhanced, thereby enhancing the structural strength of the vehicle roof 100.
Setting mode II: the second reinforcing layer 22 is disposed on the second carrying portion 102. The length of the second reinforcing layer 22 in the second direction Y is the same as the length of the second bearing portion 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 bearing portion 102 in the first direction X.

Fig. 14 is a flowchart of a method for manufacturing a vehicle ceiling according to an embodiment of the application. This embodiment is a further improvement over the previous embodiments in that: in this embodiment, a reinforcing adhesive layer is further formed on the material layer of the first bearing portion and the substrate 14, or on the material layer of the first bearing portion and the second adhesive layer.

As shown in fig. 15, since the face material layer 19 is disposed adjacent to the second adhesive layer 15, the weight per unit area of the second adhesive layer 15 is set low in order to avoid the face material layer 19 from penetrating. Further, since the glass fiber layer 21 is disposed between the second adhesive layer 15 and the second glass fiber layer 16, the adhesion of the second adhesive layer 15 may be difficult to stabilize, and thus, by providing the reinforcing adhesive layer 20, 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 can be ensured, thereby ensuring the structural stability of the vehicle ceiling 100.
It will be appreciated that the reinforcing adhesive layer 20 shown in fig. 15 is disposed between the substrate 14 and the second adhesive layer 15, and in practical application, the reinforcing adhesive layer 20 may also be disposed between the second adhesive layer 15 and the second glass fiber layer 16, so as to achieve the same technical effect.
In some embodiments, the second adhesive layer 15 is integrally formed with the reinforcing adhesive layer 20. That is, in the process of spray molding the second adhesive layer 15, the unit area weight of the second adhesive layer 15 may be increased, as shown in fig. 10, the thickness of the second adhesive layer 15 may be increased, the reinforcing adhesive layer 20 may be molded without an additional process, the bonding of the second glass fiber layer 16 and the glass fiber layer 21 may be achieved by the separate second adhesive layer 15, and the production efficiency of the vehicle ceiling 100 may be improved.
