[0022] The following is for reference. Figures 1-3 The roof assembly 100 according to an embodiment of the present invention can reduce the release of VOC substances and provide a more environmentally friendly and safer in-vehicle environment.

[0023] like Figure 1As shown, the canopy assembly 100 according to an embodiment of the present invention includes: a frame structure 1 and a fabric assembly 2.

[0024] The frame structure 1 is a supporting component of the roof assembly 100. Specifically, the frame structure 1 provides support for the fabric assembly 2, enabling the fabric assembly 2 to provide shelter for the vehicle interior. The frame structure 1 includes a roof frame 11, which comprises a core panel assembly 111 and two non-woven fabric assemblies 112. The core panel assembly 111 is positioned between the two non-woven fabric assemblies 112. In other words, non-woven fabric assemblies 112 can be respectively mounted on both sides of the core panel assembly 111. For example, one non-woven fabric assembly 112 can be bonded to one side of the core panel assembly 111, and the other non-woven fabric assembly 112 can be bonded to the other side of the core panel assembly 111, thereby forming the roof frame 11 to support the fabric assembly 2.

[0025] Furthermore, the nonwoven fabric assembly 112 includes a first barrier membrane 1121. That is, the first barrier membrane 1121 can be installed together with the nonwoven fabric body 1122 on the core board assembly 111, thereby isolating the core board assembly 111 from the external environment and reducing the emission of VOCs or other substances.

[0026] Both nonwoven fabric components 112 can be provided with a first barrier film 1121, thereby isolating both sides of the core panel component 111 from the external environment, so that the first barrier film 1121 can further reduce the VOC release of the core panel component 111 and provide a safer and more environmentally friendly in-vehicle environment.

[0027] Fabric assembly 2 is stacked on one side of skeleton structure 1, and fabric assembly 2 includes a second barrier membrane 21. That is, fabric assembly 2 can be stacked with skeleton structure 1, skeleton structure 1 can provide support for fabric assembly 2 so that fabric assembly 2 can be stably installed on ceiling assembly 100, and the second barrier membrane 21 can further isolate skeleton structure 1 from the external environment, thereby significantly reducing the release of VOC substances.

[0028] Furthermore, the ceiling assembly 100 can reduce the amount of polymeric materials that generate VOCs, thereby further reducing the amount of VOCs released from the ceiling assembly 100.

[0029] According to the roof assembly 100 of this utility model embodiment, by setting two first barrier films 1121 in the frame structure 1, the frame structure 1 can be isolated from the outside world to reduce the release of harmful substances such as VOCs, that is, the frame structure 1 releases less VOC substances into the air. In addition, the second barrier film 21 in the fabric structure can further block the frame structure 1. Thus, through the first barrier film 1121 and the second barrier film 21, the release of harmful substances such as VOCs can be greatly reduced, providing passengers with a safe and environmentally friendly vehicle interior space.

[0030] In some embodiments, the nonwoven fabric assembly 112 further includes a nonwoven fabric body 1122, which is stacked with a first barrier film 1121, and the nonwoven fabric body 1122 is located on the side of the first barrier film 1121 facing away from the core board assembly 111. That is, the first barrier film 1121 is disposed between the core board assembly 111 and the nonwoven fabric body 1122, that is, the core board assembly 111 and the nonwoven fabric body 1122 are separated by the first barrier film 1121. As a result, the VOC substances released from the core board assembly 111 to the nonwoven fabric body 1122 can be reduced, thereby reducing the VOC substances released from the core board assembly 111 to the external environment.

[0031] Specifically, such as Figure 1 As shown, nonwoven fabric assemblies 112 are provided on both sides of the core board assembly 111, and the two nonwoven fabric assemblies 112 isolate the nonwoven fabric body 1122 from the core board assembly 111 through the first barrier film 1121. That is, two first barrier films 1121 are stacked on both sides of the core board assembly 111, and the nonwoven fabric body 1122 is stacked on the side of the two first barrier films 1121 away from the core board assembly 111. Thus, the two nonwoven fabric bodies 1122 cannot directly contact the core board assembly 111, and the core board assembly 111 cannot penetrate the nonwoven fabric body 1122 through the first barrier film 1121, thereby reducing the release of VOCs from the core board assembly 111. Moreover, the two first barrier films 1121 can completely cover the two sides of the core board assembly 111, which helps to reduce the contact area between the core board assembly 111 and the external environment, and reduce the release of VOCs to the outside world.

[0032] Among them, the non-woven fabric component 112 can reduce the use of release agent and the large molecular substances attached to the ceiling frame 11 during the molding process, thereby reducing the adhesion of VOC substances.

[0033] In some embodiments, the fabric assembly 2 further includes a canopy fabric 22, which is stacked with the second barrier film 21, with the canopy fabric 22 located on the side of the second barrier film 21 facing away from the skeleton structure 1. That is, the second barrier film 21 is disposed between the canopy fabric 22 and the skeleton structure 1, i.e., the second barrier film 21 separates the canopy fabric 22 and the skeleton structure 1, so that the skeleton structure 1 can reduce the amount of VOCs released from the canopy fabric 22.

[0034] Specifically, such as Figure 1 As shown, the second barrier membrane 21 is disposed above the frame structure 1, and the headliner fabric 22 is disposed above the second barrier membrane 21, that is, the fabric assembly 2 is disposed above the frame structure 1. At this time, the frame structure 1 is in direct contact with the second barrier membrane 21. Thus, the VOC substances released by the frame structure 1 are blocked by the second barrier membrane 21 in the fabric assembly 2. That is, the VOC substances released by the frame structure 1 cannot be released through the second barrier membrane 21 to the side of the fabric assembly 2 away from the frame structure 1. When the headliner assembly 100 is installed in the vehicle, the fabric assembly 2 can be positioned towards the interior space. In this way, a first barrier membrane 1121 and a second barrier membrane 21 are disposed between the core panel assembly 111 and the interior space. That is, the two barrier membranes isolate the interior space from the core panel assembly 111, thereby significantly reducing the release of VOC substances from the core panel assembly 111 towards the interior space, thus providing a safe and environmentally friendly interior space for the occupants.

[0035] In some embodiments, a fiberglass mat 113 is provided between each nonwoven fabric assembly 112 and the core board assembly 111. That is, two fiberglass mats 113 can be provided on the core board assembly 111, with the two fiberglass mats 113 respectively located on both sides of the core board assembly 111. It should be noted that the fiberglass mat 113 is an ideal basic skeleton and reinforcing material. In the roof assembly 100, the fiberglass mat 113 can provide support for other roof materials to ensure that the roof assembly 100 can maintain a preset shape and reduce the collapse and deformation of the roof assembly 100 under gravity. Furthermore, the fiberglass mat 113 has high strength and light weight, which can provide sufficient structural strength for the roof assembly 100 while meeting the vehicle's lightweight requirements.

[0036] Specifically, such as Figure 1 As shown, there can be two fiberglass mats 113, which can be disposed on both sides of the core panel assembly 111, that is, the core panel assembly 111 is disposed between the two fiberglass mats 113. Thus, the two fiberglass mats 113 can simultaneously strengthen the structural strength of the core panel assembly 111. At the same time, the two fiberglass mats 113 can provide support for the nonwoven fabric assembly 112 connected to them, so that the nonwoven fabric assembly 112 can be relatively fixed to both sides of the core panel assembly 111. Thus, the two fiberglass mats 113 can strengthen the structural strength of the roof assembly 100 and meet the vehicle's lightweight requirements.

[0037] In some embodiments, the core board assembly 111 includes an adhesive mixing layer 1111, a first polyurethane adhesive layer 1112, a PU sheet 1113, and a second polyurethane adhesive layer 1114, which are stacked sequentially. In other words, in the core panel assembly 111, a first polyurethane adhesive layer 1112 and a second polyurethane adhesive layer 1114 are respectively provided on both sides of the PU sheet 1113. The first polyurethane adhesive layer 1112 and the second polyurethane adhesive layer 1114 can bond the fiberglass mat 113 on both sides of the PU sheet 1113. Thus, the fiberglass mat 113 on both sides of the PU sheet 1113 can be bonded to the PU sheet 1113 through the first polyurethane adhesive layer 1112 and the second polyurethane adhesive layer 1114, thereby strengthening the structure of the PU sheet 1113. The first polyurethane adhesive layer 1112 and the second polyurethane adhesive layer 1114 can enhance the sound insulation and vibration reduction performance of the ceiling assembly 100. Furthermore, an adhesive mixing layer 1111 is also provided on the other side of the first polyurethane adhesive layer 1112. Thus, the fabric assembly 2 can be provided on the side of the PU sheet 1113 where the adhesive mixing layer 1111 is provided, thereby improving the connection strength between the fabric assembly 2 and the frame structure 1 and reducing the probability of the fabric assembly 2 detaching from the frame structure 1.

[0038] Specifically, such as Figure 1 As shown, the adhesive mixing layer 1111, the first polyurethane adhesive layer 1112, the PU sheet 1113, and the second polyurethane adhesive layer 1114 are stacked sequentially. This allows the two sides of the PU sheet 1113 to be bonded to the fiberglass felt 113, which facilitates the connection and fixation of the internal structure of the roof assembly 100. In addition, the first polyurethane adhesive layer 1112 and the second polyurethane adhesive layer 1114 can absorb the vibration generated during vehicle operation, thereby reducing the transmission of vibration of the roof assembly 100 to the vehicle interior space, and can also absorb noise, improving the NVH performance of the vehicle.

[0039] Furthermore, an adhesive mixing layer 1111 is provided on one side of the PU sheet 1113 where the first polyurethane adhesive layer 1112 is provided. This improves the bonding strength of that side of the PU sheet 1113, allowing the fabric assembly 2 to be installed on the side of the PU sheet 1113 where the first polyurethane adhesive layer 1112 is provided. This enhances the connection strength between the fabric assembly 2 and the frame structure 1, thereby improving the overall strength of the roof assembly 100. Alternatively, an adhesive mixing layer 1111 can also be provided on the side of the PU sheet 1113 where the second polyurethane adhesive layer 1114 is provided, further improving the bonding strength of the structure.

[0040] The first polyurethane adhesive layer 1112 and the second polyurethane adhesive layer 1114 can be sprayed onto the surface of the PU board 1113 through a spray adhesive process, and then dried to form the core board assembly 111.

[0041] In some embodiments, the frame structure 1 further includes a third polyurethane adhesive layer, which is stacked on top of the ceiling frame 11 and located on the side of the ceiling frame 11 facing away from the fabric assembly 2. That is, the third polyurethane adhesive layer is disposed on the side of the ceiling assembly 100 facing away from the fabric assembly 2, thereby allowing accessories to be installed on the side of the ceiling assembly 100 where the third polyurethane adhesive layer is disposed.

[0042] Specifically, such as Figure 1 As shown, the frame structure 1 includes a ceiling frame 11 and a third polyurethane adhesive layer. The ceiling frame 11 includes a core board assembly 111, a fiberglass mat 113, and a nonwoven fabric assembly 112. The core board assembly 111 includes an adhesive mixing layer 1111, a first polyurethane adhesive layer 1112, a PU sheet 1113, and a second polyurethane adhesive layer 1114. The nonwoven fabric assembly 112 includes a first barrier film 1121 and a nonwoven fabric body 1122. Thus, the ceiling frame 11 consists of a nonwoven fabric body 1122, a first barrier film 1121, a fiberglass mat 113, a fiberglass mat 114, and a nonwoven fabric body 1122 from top to bottom. 13. The adhesive mixing layer 1111, the first polyurethane adhesive layer 1112, the PU sheet 1113, the second polyurethane adhesive layer 1114, the fiberglass felt 113, the first barrier film 1121, and the non-woven fabric body 1122 are stacked in sequence. A third polyurethane adhesive layer can be set on one side of the ceiling frame 11, so that the non-woven fabric body 1122 on one side of the ceiling frame 11 can be connected to the third polyurethane adhesive layer. The fabric assembly 2 can be installed on the other side. Other structures can be installed on the side of the third polyurethane adhesive layer away from the ceiling frame 11.

[0043] Among them, the non-woven fabric component 112, the fiberglass felt 113 and the core board component 111 can be processed by hot pressing composite process to bond the materials of each layer and form the ceiling frame 11, that is, to perform molding.

[0044] In some embodiments, the first barrier film 1121 and / or the second barrier film 21 are made of PE or PP material. That is, the first barrier film 1121 can be made of PE or PP material, the second barrier film 21 can be made of PE or PP material, or both the first barrier film 1121 and the second barrier film 21 can be made of PE or PP material. The specific materials can be flexibly selected. This can effectively reduce the VOC substances released from the roof assembly 100 into the vehicle interior space, thereby providing a safe and environmentally friendly in-vehicle environment for occupants.

[0045] Specifically, such as Figure 1As shown, both the first barrier membrane 1121 and the second barrier membrane 21 are made of PE or PP materials. PE material is low in cost, easy to process, has good chemical stability, excellent electrical insulation, low temperature resistance, and is non-toxic and odorless. PP material is non-toxic and odorless, has low density, high hardness, good heat resistance, and good chemical stability. Both can be used to construct the first barrier membrane 1121 or the second barrier membrane 21, and can achieve the isolation of VOC substances. That is, VOC substances in the roof assembly 100 cannot be released into the vehicle interior space through the first barrier membrane 1121 and the second barrier membrane 21, so as to provide a safe and environmentally friendly vehicle interior space for the occupants.

[0046] In some embodiments, the ceiling assembly 100 is provided with at least one connection hole 3, and an inner sealing edge 31 is formed by extrusion around the inner periphery of the connection hole 3. The thickness of the inner sealing edge 31 is configured to gradually decrease near the center of the connection hole 3. That is, the ceiling assembly 100 may be provided with one, two, or more connection holes 3, and the number of connection holes 3 is flexibly selectable. Furthermore, the inner sealing edge 31 formed by extrusion around the inner periphery of the connection hole 3 can reduce the contact area between the edge of the connection hole 3 and the external environment, thereby reducing the amount of VOC substances released from that location. As a result, the amount of VOC substances released by the ceiling assembly 100 into the external environment can be reduced.

[0047] Specifically, such as Figure 3 As shown, the roof assembly 100 may be provided with a connection hole 3, and the inner periphery of the connection hole 3 may be extruded to form an inner sealing edge 31. This allows the inner periphery of the connection hole 3 to be extruded to make it thinner, thereby reducing the contact area between the inner periphery of the connection hole 3 and the external environment. This reduces the amount of VOC substances released from the inner periphery of the connection hole 3 into the external environment by the roof assembly 100. Thus, through the first barrier film 1121, the second barrier film 21, and the inner sealing edge 31 of the connection hole 3, the release of VOC substances from the material into the external environment can be significantly reduced, thereby providing a safe and environmentally friendly in-vehicle environment for occupants.

[0048] In some embodiments, at least one outer periphery of the roof assembly 100 is extruded to form an outer edge seal 4, the thickness of which gradually decreases away from the center of the roof assembly 100. That is, one, two, or more outer peripheries of the roof assembly 100 can be extruded to form the outer edge seal 4, and the specific number can be flexibly selected. This reduces the contact area between the outer periphery of the roof assembly 100 and the external environment, thereby reducing the VOC substances released from the roof assembly 100 to the outside.

[0049] Specifically, such as Figure 2As shown, the outer periphery of the roof assembly 100 can be uniformly compressed into an outer sealing edge 4, that is, the thickness of the outer periphery of the roof assembly 100 gradually decreases along the distance from the center of the roof assembly 100. As a result, the contact area between the outer periphery of the roof assembly 100 and the external environment can be minimized to the greatest extent, thereby minimizing the amount of VOC substances released by the roof assembly 100 to the external environment through the outer periphery, thus reducing the amount of VOC substances released into the vehicle interior space, and providing occupants with a safe and environmentally friendly vehicle interior space.

[0050] This utility model also proposes a vehicle.

[0051] The vehicle according to the present invention includes a roof assembly 100 of any of the above embodiments. By providing two first barrier films 1121 and one second barrier film 21, the release of harmful substances such as VOCs from the roof assembly 100 can be reduced. Specifically, the first barrier films 1121 and the second barrier film 21 can cooperate to form a closed structure in the roof assembly 100 to reduce the emission of harmful substances such as VOCs. Furthermore, the inner periphery of the connecting hole 3 is configured as an inner sealing edge 31, and the outer periphery of the roof assembly 100 is configured as an outer sealing edge 4, which further reduces the contact area between the material and the external environment, thereby reducing the release of harmful substances such as VOCs into the external environment and providing a safe and environmentally friendly in-vehicle environment for occupants.
