[0009] In an exemplary embodiment of the present application, the first buckle and the second buckle are engaged and fixed with an interference of 1 to 3 mm.

[0010] In an exemplary embodiment of the present application, the top interior panel is provided with a second blast line, the second blast line being located closer to the edge of the top interior panel than the first blast line.

[0011] In an exemplary embodiment of the present application, the top sheet metal is provided with a shielding frame, and the shielding frame is provided between the gas generator and a reading light on the top interior panel.

[0012] In an exemplary embodiment of the present application, a baffle is provided between the gas generator and the curtain airbag, and the baffle is fixed to the top sheet metal.

[0013] In the present exemplary embodiment, the bottom of the baffle is configured to be curved towards the gas generator.

[0014] In an exemplary embodiment of the present application, a wire harness hole is provided in the top interior panel, a wire harness card is inserted into the wire harness hole, and a cable is fixed by the wire harness card.

[0015] In an exemplary embodiment of the present application, the vehicle ceiling further includes a cutout area provided in the top interior panel, and a reinforcing frame fixedly positioned on the upper side of the top interior panel along the edge of the cutout area, the reinforcing frame being connected to the top sheet metal via a first connecting member, a front end of the top interior panel being connected to the top sheet metal via a second connecting member, and a rear end of the top interior panel being connected to the top sheet metal via a third connecting member.

[0016] In an exemplary embodiment of the present application, the first connecting member includes a magnetically attracted member, one end of which is attached to the iron piece on the top metal plate and the other end of which is fixed to the reinforcing frame, a protrusion is provided at the bottom of the magnetically attracted member, the reinforcing frame is provided with an insertion hole which coincides with the bottom cross section of the magnetically attracted member with the protrusion and prevents the magnetically attracted member from separating from the reinforcing frame after the protrusion passes through the insertion hole and is rotated, the magnetically attracted member includes a magnetically attracted portion and an attachment portion, both sides of the attachment portion are provided with plastically deformable balance portions, the balance portions are provided with support portions, and the support portions support the attachment portion after the balance portions are deformed.

[0017] In an exemplary embodiment of the present application, a first mounting hole is provided at the front end of the top sheet metal, and a first deforming portion is provided on the second connecting member, and when the second connecting member is inserted into the first mounting hole, the first deforming portion elastically deforms, and when the second connecting member is inserted into a predetermined position, the deformation of the first deforming portion is reduced, and the first deforming portion restricts the second connecting member from moving away from the first mounting hole, and a second mounting hole is provided on the second connecting member on a side closer to the top interior panel, and a second deforming portion is provided on the second connecting member, and when a self-tapping screw is screwed into the second mounting hole, the self-tapping screw compresses and deforms the second deforming portion, restricting the second connecting member from moving away from the first mounting hole, and the deformation direction of the first deforming portion is perpendicular to the deformation direction of the second deforming portion.

[0020] In combination with the prior art, the beneficial effects of the present invention are as follows:

[0021] Without the use of safety handles or screws, conventional vehicle ceilings cannot ensure that they will not collapse when a curtain airbag is deployed. The top interior panel of the present application has a first blast line in the area corresponding to the installation location of the curtain airbag. When the curtain airbag is deployed, the first blast line area is more likely to break, guiding the curtain airbag to deploy quickly and reducing impact on other areas of the top interior panel. By arranging a few mushroom buckles along the first blast line, the connection between the top interior panel and the top sheet metal in the first blast line area is strengthened, ensuring a stable connection between the top interior panel and the top sheet metal when the curtain airbag is deployed and the first blast line breaks, preventing the top interior panel from falling off.

[0022] The second buckle of the present application is embedded in the top interior panel and does not penetrate the top interior panel, preventing it from being exposed inside the vehicle. This improves the aesthetics and appearance of the top interior panel inside the vehicle, thereby increasing the competitiveness of the product.

[0028] The present application provides a vehicle ceiling including a top sheet metal 200, a top interior panel 1100, and a mushroom buckle 1200. Referring to Figure 6, a curtain airbag 1300 and a gas generator 1310 are provided near the side edge of the top sheet metal 200. The gas generator 1310 is used to quickly generate gas to inflate the curtain airbag 1300 so that the curtain airbag 1300 can be rapidly inflated and deployed. A first blast line 1110 is provided in an area of ​​the top interior panel 1100 corresponding to the mounting position of the curtain airbag 1300. When the curtain airbag 1300 is inflated and deployed, the area of ​​the first blast line 1110 is easily broken and torn, so that the curtain airbag 1300 can break through the top interior panel 1100 and deploy inside the vehicle, protecting the occupants inside the vehicle.

[0029] 1 , a mushroom buckle 1200 is provided between the top sheet metal 200 and the top interior panel 1100 to connect and secure the top sheet metal 200 and the top interior panel 1100. A plurality of mushroom buckles are provided between the top sheet metal 200 and the top interior panel 1100 along the first blast line 1110 to strengthen the connection strength between the first blast line 1110 area, the top sheet metal 200, and the top interior panel 1100, and to prevent the top interior panel 1100 from separating from the top sheet metal 200 when a curtain airbag 1300 is deployed inside the vehicle along the first blast line 1110. Illustratively, to effectively protect the driver and passengers inside the vehicle, curtain airbags 1300 are provided on both sides of the top sheet metal 200, and first blast lines 1110 are also provided on both sides of the top interior panel 1100. A plurality of mushroom buckles 1200 may be provided on one side, for example, two, three, four or more, and are arranged symmetrically on both sides. In one embodiment, three mushroom buckles 1200 are provided on one side, and at least one mushroom buckle 1200 is provided in an area corresponding to the gas generator 1310, where the impact force of the curtain airbag 1300 is strongest. Providing the mushroom buckle 1200 in this area effectively ensures that the top interior panel 1100 does not separate from the top sheet metal 200 when the curtain airbag 1300 collides.

[0030] 1 and 2 , in one embodiment of a vehicle ceiling, the mushroom buckle 1200 is located on the side of the first blast line 1110 that is away from the edge of the top interior panel 1100. In other words, the first blast line 1110 is located near the edge of the top interior panel 1100, and the mushroom buckle 1200 is closer to the center of the top interior panel 1100 than the first blast line 1110. When the curtain airbag 1300 deploys, the first blast line 1110 is torn and the main weight of the top interior panel 1100 is concentrated in the central region. By locating the mushroom buckle 1200 on the side closer to the center of the top interior panel 1100, even after the top interior panel 1110 is torn, the mushroom buckle 1200 effectively ensures that the top interior panel 1100 still supports the top interior panel 1100 and prevents the top interior panel 1100 from separating from the top sheet metal 200.

[0031] 4, in one embodiment of a vehicle ceiling, mushroom buckle 1200 includes a first buckle 1210 and a second buckle 1220, which are removably fastened to each other. In one embodiment, mushroom buckle 1200 is a mushroom buckle, and first buckle 1210 and second buckle 1220 are fitted together with an interference of 1 to 3 mm, and the interference range is any value between 1 and 2 mm, such as 1 mm, 2 mm, 3 mm, 1 mm, 3 mm, etc. The interference between first buckle 1210 and second buckle 1220 ensures the stability of the connection of mushroom buckle 1200 while reducing material waste and saving costs.

[0032] 4, in one embodiment of a vehicle ceiling, a first buckle 1210 is engaged with the top sheet metal 200, and a second buckle 1220 is embedded in the top interior panel 1100 on a side closer to the top sheet metal 200, and the side of the second buckle 1220 away from the top sheet metal 200 does not penetrate the top interior panel 1100. Because the second buckle 1220 is embedded in the top interior panel 1100 and does not penetrate it, it is possible to ensure the stability of the connection between the top interior panel 1100 and the top sheet metal 200, and to prevent the second buckle 1220 from being exposed inside the vehicle body and affecting the interior appearance, thereby effectively improving the neatness and aesthetics of the vehicle ceiling and improving the competitiveness of the vehicle.

[0033] 2 and 3, in one embodiment of a vehicle ceiling, a mushroom buckle base 1120 is provided on a side of a top interior panel 1100 that is closer to the top metal sheet 200. The mushroom buckle base 1120 is provided with a sliding groove 1121. A second buckle 1220 is slidably connected to the sliding groove 1121. The sliding groove 1121 restricts the second buckle 1220 from disengaging from the sliding groove 1121 in a direction away from the sliding groove 1121. By providing the mushroom buckle base 1120 on the top interior panel 1100 and the sliding groove 1121 that is slidably connected to the second buckle 1220 in the mushroom buckle base 1120, the second buckle 1220 can be easily attached, and the operation is convenient and simple, reducing the workload of workers and improving production efficiency. In one embodiment, the second buckle 1220 is T-shaped, and the sliding groove 1121 is a T-shaped groove. The T-shaped second buckle 1220 and the T-shaped groove are easily fitted together for installation, effectively preventing the second buckle 1220 from coming off the mushroom buckle base 1120 in a direction away from the sliding groove 1121, ensuring a stable connection between the second buckle 1220 and the mushroom buckle base 1120, and thereby preventing the top interior panel 1100 from falling off. Illustratively, the tight fit between the second buckle 1220 and the sliding groove 1121 prevents the second buckle 1220 from coming off the sliding groove 1121 after installation, ensuring a stable connection.

[0034] 2 , in one embodiment of the vehicle ceiling, a blocking portion 1122 is provided at one end of the sliding groove 1121, and the blocking portion 1122 closes the sliding groove 1121, thereby restricting the second buckle 1220 from sliding out of the sliding groove 1121 in the sliding direction. The provision of the blocking portion 1122 prevents the second buckle 1220 from sliding out of the sliding groove 1121, facilitating positioning and installation, while effectively improving the fit between the second buckle 1220 and the mushroom buckle base 1120 and effectively ensuring a stable connection between the second buckle 1220 and the mushroom buckle base 1120. In one embodiment, the blocking portion 1122 is a protrusion provided at the center of the sliding groove 1121, and the protrusion only needs to partially close the sliding groove 1121 to restrict the second buckle 1220 from sliding out. The protrusion partially closes the sliding groove 1121, reducing the material of the mushroom buckle base 1120, thereby reducing the cost and weight.

[0035] 3 , in one embodiment of the vehicle ceiling, the direction in which the second buckle 1220 slides into the sliding groove 1121 is not the same as the deployment direction of the curtain airbag 1300. Because the direction in which the second buckle 1220 slides into the sliding groove 1121 and the deployment direction of the curtain airbag 1300 are not the same, it is possible to prevent the second buckle 1220 from coming off the sliding groove 1121 when the curtain airbag 1300 deploys, and it is possible to effectively improve the connection stability between the top sheet metal 200 and the top interior panel 1100. Illustratively, the direction in which the second buckle 1220 slides into the sliding groove 1121 is perpendicular to the deployment direction of the curtain airbag 1300.

[0036] In one embodiment of the vehicle ceiling, the blocking portion 1122 is provided at one end of the sliding groove 1121 away from the curtain airbag 1300, and the second buckle 1220 can only slide out of the sliding groove 1121 from the end other than the blocking portion 1122 of the sliding groove 1121. By providing the blocking portion 1122 at one end of the sliding groove 1121 away from the curtain airbag 1300, when the curtain airbag 1300 collides with the first blast line 1110, both sides of the first blast line 1110 receive the impact force from a direction away from the first blast line 1110. By providing the blocking portion 1122 at the end away from the curtain airbag 1300, when the curtain airbag 1300 deploys, the top interior panel 1100 receives the impact force from a direction away from the first blast line 1110. The blocking portion 1122 prevents the second buckle 1220 from coming off the sliding groove 1121, thereby preventing the top interior panel from coming off the top sheet metal 200 and improving the stability and firmness of the connection between the top interior panel 1100 and the top sheet metal 200.

[0037] In one embodiment for a vehicle ceiling, the mushroom buckle base 1120 may be made of a metal material or a hard plastic material, preferably a metal material that can ensure the impact resistance of the mushroom buckle base 1120. In one embodiment, the mushroom buckle base 1120 is fixed to the side of the top interior panel 1100 that is closer to the top sheet metal 200 with a hot melt adhesive to ensure a firm fixation. The mushroom buckle base 1120 replaces the original handle fixing structure, and the appearance is smooth and not exposed, which not only ensures a firm fixation but also improves the aesthetic effect.

[0038] 1 , in one embodiment of a vehicle ceiling, a mushroom buckle base 1120 is fixed to a reinforcing frame of the top interior panel 1100 to improve the connection strength between the top interior panel 1100 and the top sheet metal 200. In one embodiment, the mushroom buckle base 1120 is made of a metal plate, which is bent to have a fixing portion that is fixed to the reinforcing frame of the top interior panel 1100. The metal plate has an opening with a sliding groove 1121 for receiving the second buckle 1220. Bent portions are provided on both sides of the opening, which cooperate with the second buckle 1220 to limit wobbling of the second buckle 1220. Compared to providing the opening directly on a flat surface, providing the bent portions increases the strength of the opening and prevents the metal plates on both sides of the opening from being deformed by the gravity of the top interior panel 1100, improving load-bearing capacity.

[0039] 1, in one embodiment of a vehicle ceiling, a top interior panel 1100 is provided with a second blast line 1111, which is located closer to the edge of the top interior panel 1100 than the first blast line 1110. By locating the second blast line 1111 on the side closer to the edge of the top interior panel 1100 than the first blast line 1110, the top interior panel 110 can be bent twice, ensuring that the curtain airbag 1300 can be deployed quickly and completely, preventing the top interior panel 1100 from being subjected to excessive impact, and protecting the integrity of portions of the top interior panel 1100 outside the designated tear area. In one embodiment, the second blast line 1111 is located at the connection between the gas generator 1310 and the curtain airbag 1300. When the gas generator 1310 generates gas to inflate the curtain airbag 1300, the impact force between the curtain airbag 1300 and the gas generator 1310 is greatest. By providing the second blast line 1111 at the connection between the gas generator 1310 and the curtain airbag 1300, the top interior panel 1100 here is more likely to be destroyed. In particular, if the first blast line 1110 is torn but the impact force of the curtain airbag 1300 cannot be quickly released, the second blast line 1111 will be torn and destroyed, causing the top interior panel 1100 here to fold twice, ensuring that the curtain airbag 1300 is fully deployed and preventing other areas of the top interior panel 1100 from being damaged by the impact.

[0040] 5 and 7, in one embodiment of a vehicle ceiling, a shielding frame 1330 is provided on the top metal sheet 200, and the shielding frame 1330 is provided between the gas generator 1310 and the reading lamp 1150 on the top interior panel 100. Preferably, the shielding frame 1330 is provided at the connection portion between the gas generator 1310 and the curtain airbag 1300. For example, the shielding frame 1330 is a metal member, and when the gas generator 1310 rapidly generates gas, the connection between the curtain airbag 1300 and the gas generator 1310 rapidly expands, and by installing the shielding frame 1330, the curtain airbag 1300 is shielded, thereby preventing the reading light 1150 on the top interior panel 1100 from being impacted when the curtain airbag 1300 rapidly expands, and preventing the reading light 1150 on the top interior panel 1100 from flying out when the curtain airbag 1300 deploys, thereby ensuring the safety of the driver and passengers inside the vehicle.

[0041] In one embodiment of the vehicle ceiling, the shielding frame 1330 may be fixed to the top metal plate 200 by welding, bolting, etc., and for ease of installation, the shielding frame 1330 is preferably fixed to the top metal plate 200 by bolts. In one embodiment, the top metal plate 200 is provided with a hook hole, and the shielding frame 1330 is provided with a first hook portion.

[0042] 9 , in one embodiment of a vehicle ceiling, a hook hole is provided in the top metal sheet 200, and a first hook portion 1331 is provided in the shielding frame 1330. The first hook portion 1331 cooperates with the hook hole to initially position and restrict the initial position of the shielding frame 1330, making it easier to secure the shielding frame 1330 to the top metal sheet 200. For example, when the shielding frame 1330 and the top metal sheet 200 are secured with a bolt, the first hook portion 1331 engages with the hook hole to prevent the shielding frame 1330 from rotating with the bolt, facilitating securement. In one embodiment, the hook hole is an elongated hole, and the first hook portion 1331 is provided with a groove in the same direction as the hook hole. In use, after the first hook portion 1331 passes through the hook hole, it moves along the hook hole and inserts the top metal sheet 200 at the edge of the hook hole into the groove, thereby engaging the first hook portion 1331 with the hook hole. Preferably, the thickness of the first hook portion 1331 is the same as the width of the hook hole, so that when the groove of the first hook portion 1331 engages with the top metal sheet 200, the hook hole restricts rotation of the first hook portion 1331. On the one hand, this facilitates positioning of the shielding frame 1330, and on the other hand, it prevents the shielding frame 1330 from rotating when the shielding frame 1330 and the top metal sheet 200 are connected with bolts, ensuring that the installation position and angle of the shielding frame 1330 are appropriate.

[0043] In one embodiment of the vehicle ceiling, the main body of the shielding frame 1330 is arc-shaped, and the arc-shaped shielding frame 1330 is adapted to the gas generator 1310, thereby applying uniform force to the main body of the shielding frame 1330, improving the impact resistance of the shielding frame 1330 and also expanding the protective range of the reading lamp 1150 on the top interior panel 1100. Preferably, the arc is directed toward the axis of the connection between the gas generator 1310 and the curtain airbag 1300, ensuring the protective effect of the shielding frame 1330.

[0044] 9 , in one embodiment of the vehicle ceiling, a shielding frame 1330 is provided with a shielding reinforcement rib 1332, preferably provided on a side of the shielding frame 1330 opposite the gas generator 1310. Providing the shielding reinforcement rib 1332 can improve the impact resistance of the shielding frame 1330 and reduce deformation of the shielding frame 1330 due to the impact of the curtain airbag 1300. Exemplarily, the shielding reinforcement rib 1332 may be welded to the side of the shielding frame 1330 opposite the gas generator 1310, may be provided on the shielding frame 1330 by machining, or may be formed by pressing the shielding frame 1330. Preferably, the shielding reinforcement rib 1332 is formed by pressing the shielding frame 1330; on the other hand, since no additional material is required, the weight of the shielding frame 1330 is reduced, the amount of material used is reduced, and costs are saved. On the other hand, a portion of the shield reinforcement rib 1332 formed by pressing forms a recess toward the curtain airbag 1300, which can extend the action distance and action time of the curtain airbag 1300 relative to the shield frame 1330, effectively reducing the impact of the curtain airbag 1300 on the shield frame 1332 and improving the impact resistance of the shield frame 1330. Illustratively, the edges of the shield reinforcement rib 1332 are curved, which can reduce stress concentration when the shield frame 1330 is impacted and improve the strength of the shield frame 1330 compared to straight edges. In one embodiment, the middle portions on both sides of the shield reinforcement rib 1332 are recessed toward the center of the shield reinforcement rib 1332. When the shield reinforcement rib 1332 is formed by press processing, the surface area of ​​the shield plate 330 at the shield reinforcement rib becomes smaller, and when an impact is received, the pressure applied to the surface increases, and the middle parts on both sides of the shield reinforcement rib 1332 protrude toward the center of the reinforcement rib 332, increasing the area of ​​initial contact between the shield frame 332 and the curtain airbag 1300 and improving impact resistance.Preferably, the shield reinforcement rib 1332 is butterfly-shaped, and the upper central portion of the shield reinforcement rib 1332 also protrudes toward the center of the shield reinforcement rib 1332, further improving the impact resistance of the shield frame 1330. The protruding end points of the shield reinforcement rib 1332 are all arc-shaped, which avoids stress concentration and improves the impact resistance of the shield frame 1330.

[0045] 9 , in one embodiment of a vehicle ceiling, a shield frame 1330 is provided with an engagement portion 1333 protruding toward a top interior panel 1100, and an engagement hole 13331 is provided in the engagement portion 1333, which receives the insertion of a first buckle 1210. In the area where the reading light 1150 is provided, the distance between the top interior panel 1100 and the top sheet metal 200 is relatively large, and since a gas generator 1310 is provided in this area, the impact force when the curtain airbag 1300 deploys is relatively large. If the top sheet metal 200 and the top interior panel 1100 are directly fastened to each other via a mushroom buckle 1200, the mushroom buckle 1200 would need to be longer and customized separately. However, the longer the mushroom buckle 1200, the lower the fastening and strength. By providing shield frame 1330 with engaging portion 1333 that protrudes toward top interior panel 1100, top interior panel 1100 and top metal sheet 200 can be easily connected with mushroom buckle 1200. Since shield frame 1330 itself has a protective effect and the connection strength with top metal sheet 200 is relatively high, first buckle 1210 can be provided on shield frame 300 to ensure a strong and stable connection.

[0046] In one embodiment of a vehicle ceiling, the bottom of the shielding frame 1330 is bent in a direction away from the curtain airbag 1300. The shielding frame 300 is preferably a metal frame, and by bending the bottom of the shielding frame 1330 in a direction away from the curtain airbag 1300, it is possible to prevent the curtain airbag 1300 from coming into contact with the edge of the shielding frame 1330 and damaging the curtain airbag 1300 when the curtain airbag 1300 collides, and it also effectively protects the ambient light on the top interior panel 1100, further protecting the curtain airbag 1300 and preventing the curtain airbag 1300 from being damaged and losing its protective effect.

[0047] 6 and 8, in one embodiment of a vehicle ceiling, a baffle 1320 is provided between a gas generator 1310 and a curtain airbag 1300. The gas generator 1310 is typically arranged in parallel with the curtain airbag 1300 to enable rapid inflation of the curtain airbag 1300. By providing the baffle 1320 between the curtain airbag 1300 and the gas generator 1310, it is possible to effectively prevent the curtain airbag 1300 from impacting the gas generator 1310 during deployment, thereby protecting the gas generator 1310. In one embodiment, the lower part of the baffle 1320 faces the first blast line 1110 to guide the deployment direction of the curtain airbag 1300, ensuring that the curtain airbag 1300 deploys quickly in a predetermined direction, thereby improving the protection of the driver and passengers inside the vehicle. Illustratively, the lower edge of the baffle 1320 is bent toward the gas generator 1310, in other words, the lower edge of the baffle 1320 is bent in a direction away from the curtain airbag 1300, so that when the curtain airbag 1300 deploys, it does not come into contact with the edge of the baffle 1320 and prevents damage to the curtain airbag 1300. Preferably, the bent portion at the bottom of the baffle 1320 is curved so as not to scratch the curtain airbag 1300.

[0048] 10 and 11, in one embodiment of the vehicle ceiling, the baffle 1320 is fixed to the top metal sheet 200. When the curtain airbag 1300 is deployed, the baffle 1320 is subjected to a large impact force. Therefore, if the baffle 1320 is directly fixed to the top metal sheet 200, the protective effect of the baffle 1320 can be effectively ensured and the baffle 1320 can be prevented from falling off when the curtain airbag 1300 is deployed. In one embodiment, the baffle 1320 is connected to the top metal sheet 200 with bolts to ensure a stable connection. The baffle 1320 is provided with a second hook portion 1321, the structure and function of which are the same as those of the first hook portion. The second hook portion 1321 engages with the hook hole of the top metal plate 200 to realize the initial positioning and initial position restriction of the baffle 1320, prevent the baffle 1320 from rotating when the bolts are tightened, and ensure that the installation position and installation angle of the baffle 1320 are appropriate.

[0049] 12 and 13, in one embodiment of a vehicle ceiling, a top interior panel 1100 is provided with a wire harness hole, and a wire harness card 1400 is inserted into the wire harness hole, and the wire harness card 1400 secures a cable 1410. Conventionally, the cable 1410 is directly attached to the top interior panel 1100. However, if the top interior panel 1100 is provided with a large skylight and many integrated components, the area where the cable 1410 is attached is directly reduced. For example, the top interior panel 1100 is provided with a skylight frame 1140, and since the weight of the skylight frame 1140 is relatively concentrated, the skylight frame 1140 is usually provided with a fixing member connected to the top metal plate 200, which allows the skylight frame 1140 to be firmly fixed. In one embodiment, the skylight frame 1140 has a double-bent portion in an area where a fixing member is provided, and a wire harness hole is provided in the double-bent portion. The wire harness card 1400 is inserted into the wire harness hole, thereby fixing the cable 1410 to the top interior panel 1100 relatively. By providing the double-bent portion, the wire harness card 1400 can avoid the fixing members of the skylight frame 1140 and the top sheet metal 200, thereby making it easier for the wire harness card 1400 to be inserted into the wire harness hole and facilitating installation. Illustratively, the portion where the wire harness card 1400 is inserted into the wire harness hole is formed in a tree-like shape to prevent the wire harness card 1400 from falling out of the wire harness hole.

[0050] In the vehicle ceiling of the present invention, the top metal sheet 200 and the side of the top interior panel 1100 are fastened with a hidden mushroom buckle 1200, which securely connects the top interior panel 1100 and the top metal sheet 200 and improves the aesthetic appearance of the vehicle interior. The second blast line 1111 facilitates the deployment of the curtain airbag 1300. The shielding frame 1330 effectively prevents the reading light 1150 from flying out, ensuring the safety of passengers in the vehicle. The baffle 1320 guides the deployment of the curtain airbag 1300 and protects the top interior panel 1100. The wire harness card 1400 fastens the cable 1410 to the side of the skylight frame 1140, reducing noise from the cable 1410.

[0051] In conventional fixing methods, top interior panels are typically fixed to the top sheet metal using exposed rivets and handle screws. However, as vehicle requirements increase and vehicle safety improves, side handles are no longer necessary, and when side handles are eliminated, the screws for the side handles are also no longer necessary. However, other conventional fixing members cannot ensure the fixing strength between the top interior panel and the top sheet metal, and there is a risk that the top interior panel will fall off.

[0052] In view of the above, in one embodiment of the vehicle ceiling of the present application, top interior panel 1100 and top sheet metal 2000 are connected via a connecting member, and top interior panel 1100 is attached and fixed to top sheet metal 2000 by the connecting member, and an iron piece is provided on top sheet metal 2000. Illustratively, iron piece 2210 may be provided directly on top sheet metal 2000, or may be provided on skylight mechanism 2220 fixed to top sheet metal 2000.

[0053] Referring to Figure 14, in one embodiment of a vehicle ceiling, a top interior panel 1100 is mounted on a top metal sheet 2000, a cutout area is provided in the top interior panel 1100, a reinforcing frame 2110 is fixed to the edge of the cutout area, and the reinforcing frame 2110 is fixed to the upper side of the top interior panel 1100, i.e., the side of the top interior panel 1100 closest to the top metal sheet 2000.

[0054] In one embodiment, the area surrounded by the reinforcing frame 2110 is provided with an automobile skylight, and the reinforcing frame 2110 includes a skylight frame 1140. For different vehicle models, the top interior panel 1100 has different cutout areas, for example, a portion of the top interior panel 1100 is provided with two cutout areas, one at the front and one at the back, for installing two skylights. A monitor, a speaker, a camera, a reading light, etc. may be provided in a portion of the top interior panel 1100, but this can be configured according to actual needs and is not limited thereto.

[0055] 14 , in one embodiment of a vehicle ceiling, the connecting members include a first connecting member, a second connecting member 2500, and a third connecting member 2600, wherein the stiffening frame 2110 is connected to the top sheet metal 2000 via the first connecting member, the front end of the top interior panel 1100 is connected to the top sheet metal 2000 via the second connecting member 2500, and the rear end of the top interior panel 1100 is connected to the top sheet metal 2000 via the third connecting member 2600. By using a combination of multiple connecting members to fasten the top interior panel 1100 to the top sheet metal 2000 and adapting the fastening members according to the weight distribution of the top interior panel 1100, not only is both the top interior panel 1100 and the top sheet metal 2000 securely connected, but costs are also saved, and the use of larger load-bearing connecting members in areas subjected to small forces is avoided, reducing waste and improving product competitiveness.

[0056] 15 to 18, in one embodiment of a vehicle ceiling, the first connecting member includes a magnetic attraction member 300, and a magnetic attraction member 2300 is attached to the central region of the top interior panel 1100. Since a larger weight is concentrated in the central region, a load-bearing connecting member is required. The magnetic attraction member 2300 has a large load-bearing capacity, capable of bearing a load of 60 to 90 N. The magnetic attraction member 2300 is used to fasten the top interior panel 1100 and the top metal sheet 2000 together, achieving a more stable connection. In one embodiment, the top interior panel 1100 is provided with two reinforcing frames 2110, and the magnetic attraction member is provided only on the reinforcing frame 2110 at the rear of the vehicle, thereby ensuring connection strength while reducing material waste and cost.

[0057] 17 , in one embodiment of a vehicle ceiling, a magnetically attractive member 2300 includes a magnetically attractive portion 2320 and an attachment portion 2310. The magnetically attractive portion 2320 is a magnetic member for adhering to the iron piece 2210 of the top metal sheet 2000. The attachment portion 2310 supports and secures the magnetically attractive portion 2320 to the top interior panel 1100. Illustratively, the body of the attachment portion 2310 is bowl-shaped, and the magnetically attractive portion 2320 is disposed on the upper surface of the bowl. Illustratively, the attachment portion 2310 is made of Perspex to easily secure the magnetically attractive portion 2320. The attachment portion 2310 is cast to cover a portion of the magnetically attractive portion 2320 so that the magnetically attractive portion 2320 is embedded in the attachment portion 2310. In one embodiment, the magnetic attraction portion 2320 includes two portions, one portion is provided at the top center of the mounting portion 2310, and the other portion is provided in a ring shape on the upper edge of the magnetic attraction portion 2320. The upper surface of the magnetic attraction portion 2320 is slightly higher than the upper surface of the mounting portion 2310, so that the magnetic attraction portion 2320 can be easily attached to the iron piece 2210.

[0058] 18 , in one embodiment of a vehicle ceiling, a connecting portion 2311 is provided below the main body of the mounting portion 2310, and a protrusion 2312 is provided on the edge of the connecting portion 2311. An insertion hole is provided in the reinforcing frame 2110, and the cross section of the insertion hole matches the cross section of the connecting portion 312 with the protrusion 2312. When installing, first adjust the angle between the connecting portion 312 and the insertion hole to match, then insert the connecting portion 312 into the insertion hole. Once the protrusion 2312 passes through the insertion hole, rotate the magnetically attractive member 2300, and the protrusion 2312 prevents the magnetically attractive member 2300 from removing from the insertion hole. For example, the connecting portion 2311 is cylindrical, and the protrusion 2312 protrudes outward from the side of the cylinder. In one embodiment, two protrusions 2312 are provided, and the two protrusions 2312 are arranged symmetrically on both sides of the connecting portion 2311.

[0059] 18 , in one embodiment, a first locking portion 23121 is provided on the upper surface of the protrusion 2312. When the protrusion 2312 passes through the insertion hole and is rotated at a certain angle, the first locking portion 23121 is positioned below the reinforcing frame 2110. For example, the upper surface of the first locking portion 23121 is an arcuate surface. A certain degree of machining tolerance is allowed between the reinforcing frame 2110 and the iron piece 2210 of the top metal sheet 2000. As a result, the reinforcing frame 2110 and the iron piece 2210 cannot be perfectly parallel. Therefore, the provision of the first locking portion 23121 reduces the contact area between the protrusion 2312 and the reinforcing frame 2110, thereby making it easier to adjust the mounting position of the magnetically attracted member 2300 and ensuring that the magnetically attracted portion 2320 is always perfectly attracted to the iron piece 2210 even when the reinforcing frame 2110 and the top metal sheet 2000 are not perfectly parallel. For example, since the upper surface of the first locking portion 23121 is spherical, it is easy to adjust the contact angle between the protrusion 2312 and the reinforcing frame 2110, and the magnetic attraction portion 2320 can be completely attracted to the iron piece 2210 within the allowable tolerance range, thereby avoiding a gap between the iron piece 2210 and the magnetic attraction portion 2320 that would affect the attraction effect and cause problems such as abnormal noise.

[0060] 17, in one embodiment, the mounting portion 2310 is provided with plastically deformable balancing portions 2313 on both sides thereof. When the magnetically attractive member 2300 is attached to the iron piece, the balancing portions 2313 can be adjusted to adjust the overall center of gravity of the magnetically attractive member 2300. However, if the iron plate 2210 is uneven, the magnetically attractive member 2300 may tilt slightly. By adjusting the balancing portions 2313, the bottom surfaces of the balancing portions 2313 can be brought into contact with the reinforcing frame 2110. The balancing portions 2312 cooperate with the protrusions 2312 or the first locking portions 23121 to firmly clamp the reinforcing frame 2110, ensuring stable attachment of the magnetically attractive member 2300 and a stable connection between the magnetically attractive member 2300 and the iron piece 200. For example, after adjusting the balancing part 2313, the end of the balancing part 2313 rests against the mounting part 2310, and the end and bottom of the balancing part 2313 support the mounting part 2310, preventing tilting of the magnetically attracted part 2320 after installation. In one embodiment, a bending region is provided in the center region of the balancing part 2313. When the balancing part 2313 is pressed, the balancing part 2313 bends first from the bending region, making it easier to control the bending of the balancing part. When one side of the balancing part 2313 supports the mounting part 2310, the bending region causes the balancing part 2313 to form a triangle, improving support stability and ensuring a supporting effect. For example, a second locking part 23131 is provided on the bottom surface of the balancing part 2313. The provision of the second locking part 23131 reduces the contact area between the balancing part 2313 and the reinforcing frame 2110, making it easier to adjust the balancing part 2313. The second locking portion 23131 and the first locking portion 23121 can be easily clamped to both sides of the reinforcing frame 2110, ensuring the stability of the magnetic attraction member 2300. Furthermore, the bottom surface of the second locking portion 23131 is an arcuate surface, preferably a spherical surface, which makes it easy to adjust the angle between the second locking portion 23131 and the upper surface of the reinforcing frame 2110 and ensures a reliable clamping effect, thereby stably attaching the magnetic attraction member 2300 and allowing the magnetic attraction member 2300 to be more stably attracted to the iron piece.

[0061] 17 , in one embodiment, the balancing portion 2313 is provided with a support portion 2314. The support portion 2314 is provided along the extension direction of the balancing portion 2313. The cross-sectional size of the support portion 2314 is much smaller than the cross-sectional size of the balancing portion 2313. After the balancing portion 2313 is adjusted, the support portion 2314 is supported by the mounting portion 2310, preferably on the side of the mounting portion 2310. On the one hand, the support portion 2314 functions as a reinforcing rib to increase the strength of the balancing portion 2313 and ensure the supporting effect. On the other hand, the support portion 2314 can reduce the contact area with the mounting portion 2310, making it easier to find the support point and make adjustments.

[0062] In one embodiment, eight magnetic attraction members 2300 are provided, which are symmetrically arranged on both sides of the reinforcing frame 2110 along the axial direction of the vehicle to ensure the stability of the support and the stable connection between the top interior panel 1100 and the top sheet metal 2000.

[0063] In one embodiment, the first connecting member further includes a mushroom buckle 1200, where the first buckle 1210 is fixed to the top metal sheet 2000 and the second buckle 1220 is provided on the top interior panel 1100, and the first buckle 1210 and the second buckle 1220 are removably fastened to each other. In one embodiment, 23 to 30 mushroom buckles 1200 are used to fasten the top interior panel 1100 to the top metal sheet 2000, and the number may be any one of 23 to 30, such as 23, 25, 26, 28, or 30. The mushroom buckles 1200 have a weaker load-bearing capacity and are less expensive than the magnetic attraction member 2300. Using a large number of mushroom buckles 1200 ensures a reliable connection between the top interior panel 1100 and the top metal sheet 2000 and is less expensive. In one embodiment, the single mushroom buckle 1200 can provide a pulling force of 19-40 N, thereby ensuring that the top interior panel 1100 is securely fastened to the top sheet metal 500 .

[0064] In one embodiment, the top interior panel 1100 is provided with two reinforcement frames 2110, and the front reinforcement frame 2110 at the front of the vehicle has a plurality of mushroom buckles 1200 evenly spaced along its four sides. In one embodiment, a total of twelve mushroom hasps 1200 are provided along the four sides of the front reinforcement frame 2110, with four mushroom hasps 1200 along each length of the front reinforcement frame 2110 and two mushroom hasps along each width, thereby stabilizing the connection between the top interior panel 1100 and the top sheet metal 2000. Illustratively, the rear reinforcement frame 2110 of the top interior panel 1100 is also provided with a plurality of mushroom buckles 1200, which cooperate with magnetic attraction members 2300 to support the rear reinforcement frame 2110 area of ​​the top interior panel 1100. In one embodiment, the buckles on the rear reinforcement frame 2110 are arranged along the width direction of the vehicle, with four on each side. The sides of the rear reinforcement frame 2110 along the axial direction of the vehicle receive a greater force and are supported by the magnetic attraction members 2300, while the sides along the width direction of the vehicle receive a smaller force and are supported additionally by the mushroom buckles 1200, thereby firmly fastening the top interior panel 1100 to the top sheet metal and reducing manufacturing costs.

[0065] In one embodiment, since the portion along the blast line is separated from the reinforcing frame 2110, the top interior panel 1100 is provided with additional metal reinforcing members along the blast line to ensure a secure connection. The fasteners are secured to the reinforcing frame 2110 or reinforcing members of the top interior panel 1100.

[0066] 22 , in one embodiment, a front reading light bracket 2130 for mounting the front reading light is provided on the front end of top interior panel 1100. In one embodiment, after the front reading light is installed, the front reading light bracket 2130 can be covered, and the front reading light is provided with a second connecting member 2500, which cooperates with a self-tapping screw 2540 to secure top interior panel 1100 and top sheet metal 2000. When the front reading light is installed, the self-tapping screw 2540 can be covered, allowing the front reading light bracket 2130 to use an inexpensive, externally exposed connection method, thereby reducing costs and improving efficiency.

[0067] In one embodiment, in top sheet metal 2000, a first mounting hole is provided in the front reading light, and second connecting member 2500 is provided with a limiting portion 2550, second connecting member 2500 is inserted into the first mounting hole, limiting portion 2550 prevents second connecting member 2500 from being fully inserted into the first mounting hole, and in use, limiting portion 2550 is located between top interior panel 1100 and top sheet metal 2000. Illustratively, two second connecting members are provided in the front reading light to improve the connection strength of the front reading light.

[0068] In one embodiment, the front reading light bracket 2130 is fixed to the top interior panel 1100. The front reading light bracket 2130 is preferably glued to the top interior panel 1100, which not only ensures a stable fixation but also prevents the connecting member from being exposed and affecting the appearance. The front reading light bracket 2130 has a through-hole, through which a self-tapping screw 2540 passes and is then fastened to the second connecting member 2500. The end diameter of the self-tapping screw 2540 is larger than the diameter of the through-hole in the front reading light bracket 2130. The self-tapping screw 2540 and the second connecting member 2500 cooperate to fasten the front reading light bracket 2130 to the top metal plate 2000.

[0069] 23 , in one embodiment, the second connecting member 2500 is provided with a first deforming portion 2510, which elastically deforms when the second connecting member 2500 is inserted into the first mounting hole, and the deformation of the first deforming portion 2510 is reduced when the second connecting member 2500 is inserted into a predetermined position, so that the first deforming portion 2510 prevents the second connecting member 2500 from coming out of the first mounting hole. In one embodiment, there are two first deforming portions 2510, which are symmetrically disposed on both sides of the body of the second connecting member 2500. By providing two first deforming portions 2510, the second connecting member 2500 can receive a more uniform force after being locked into the first mounting hole, resulting in a more secure engagement.

[0070] 24 , in one embodiment, the first deformation portion 500 includes two first folding plates 2511, forming an obtuse angle between the two first folding plates 2511. The obtuse angles of the two first deformation portions 500 are arranged opposite each other. The upper first folding plate 2511 is inclined from top to bottom away from the center of the first mounting hole, and the lower first folding plate 2511 is inclined from top to bottom toward the center of the first mounting hole. When the first deformation portion 500 is inserted into the first mounting hole, the first folding plate 2511 deforms toward the center of the first mounting hole. The deformation of the first deformation portion 500 begins to decrease until the connecting portion of the two first folding plates 2511 is inserted into the first mounting hole, and then gradually recovers. The provision of two first folding plates 2511 prevents the second connecting member 2500 from coming off the first mounting hole. In one embodiment, the lower first folding plate 2511 is provided with a position restricting groove 25111, and the cross section of the position restricting groove 25111 is triangular, semicircular, rectangular, arc-shaped, etc. When the first deforming part 500 is removed from the first mounting hole, the wall of the first mounting hole is inserted into the position restricting groove 25111, thereby restricting the first deforming part 500 from leaving the first mounting hole and improving the load-bearing capacity of the second connecting member 2500. The arrangement of two first folding plates 2511 reduces the requirement for processing accuracy, and even if the processing error of the first deforming part 500 is large, it can be deformed and attached to the first mounting hole, thereby meeting more usage requirements.

[0071] 24 and 26, in one embodiment, a second mounting hole 2530 is provided on the side of the second connecting member 2500 closer to the top interior panel 1100, and the second connecting member 2500 is provided with a second deformation portion 2520. When a self-tapping screw 2540 is threaded into the second mounting hole 2530, the self-tapping screw 2540 presses against and deforms the second deformation portion 2520, preventing the second connecting member 2500 from coming off the first mounting hole. The addition of the second deformation portion 2520 can further improve the load-bearing capacity of the second connecting member 2500. In one embodiment, the second deformation portion 2520 includes two second folding plates 2521, with an obtuse angle between the two second folding plates 2521, and the upper second folding plate 520 at least partially blocks the second mounting hole, and when the self-tapping screw 2540 is threaded into the second mounting hole 2530, the portion of the self-tapping screw 2540 that is threaded into the first mounting hole presses the second deformation portion 2520 in a direction away from the center of the first mounting hole, thereby engaging the second folding plate 2521 above the side wall of the first mounting hole. When second connecting member 2500 is removed from the first mounting hole, second folding plate 2521 needs to deform toward the center of the first mounting hole, but self-tapping screw 2540 restricts second folding plate 2521 from deforming toward the center of the first mounting hole, thereby stabilizing the connection between second connecting member 2500 and the first mounting hole and the connection between top interior panel 1100 and top sheet metal 2000. When self-tapping screw 2540 is loosened, second folding plate 2521 deforms toward the center of the first mounting hole, which makes it easy to attach, detach, maintain, and replace front reading light bracket 2130 or top interior panel 1100.

[0072] 25, in one embodiment, the deformation direction of the first deforming portion 2510 is perpendicular to the deformation direction of the second deforming portion 2520. When a force is applied, the first deforming portion 2510 and the second deforming portion 2520 can receive the force evenly, thereby improving the service life of the second connecting member 2500.

[0073] 27 and 28, exemplarily, third connecting member 2600 is provided at the rear end of top interior panel 1100. In one embodiment, four third connecting members 2600 are provided, all of which are provided at the rear of the vehicle ceiling, which reduces the weight distribution at the rear of the vehicle ceiling but requires hidden placement. Therefore, using third connecting members 2600 that are lower in both price and load capacity than mushroom buckles 1200 not only secures top interior panel 1100 and top sheet metal 2000 but also reduces costs. Exemplarily, a third mounting hole is provided at one end of top sheet metal 2000 closer to the vehicle rear, and a buckle base 2140 is provided on top interior panel 1100, with one end of third connecting member 2600 inserted into buckle base 2140 and the other end inserted into the third mounting hole.

[0074] In one embodiment, the third connecting member 2600 is made of plastic or Perspex, and is provided with a first position regulating portion 2610, which can be elastically deformed. When the third connecting member 2600 is inserted into the third mounting hole, the first position regulating portion 2610 elastically deforms. After the third connecting member 2600 is inserted into the third mounting hole, the first position regulating portion 2610 returns to its original shape, thereby preventing the third connecting member 2600 from coming off the third mounting hole.

[0075] Referring to FIG. 28, in one embodiment, a second position regulating portion 2620 is provided at the bottom of the third connecting member 2600, and an opening is provided in the buckle base 2140. When the third connecting member 2600 is inserted into the opening of the buckle base 2140, the second position regulating portion 2620 elastically deforms. After the third connecting member 2600 is inserted into the opening of the buckle base 2140, the second position regulating portion 2620 returns to its original shape, thereby restricting the third connecting member 2600 from being detached from the buckle base 2140. In one embodiment, to reduce the cost of the third connecting member 2600, the second position restricting portion 2620 of the third connecting member 2600 is a plate-like structure with a larger cross section, and the buckle base 2140 is provided with a sliding groove, into which the second position restricting portion 2620 slides, and the sliding groove cooperates with the second position restricting portion 2620 to restrict the third connecting member 2600 from separating from the buckle base 2140 along the non-sliding groove direction. Compared with other position restricting structures, the plate-like position restricting structure can save material, simplify the structure, and be easier to use.

[0076] In one embodiment, the buckle base 2140 is bonded to one side of the top interior panel 1100, close to the top metal sheet 2000. The buckle base 2140 is trapezoidal and has a hollow structure to reduce weight. In one embodiment, the inside of the buckle base 2140 is provided with reinforcing ribs, which ensure the strength of the buckle base 2140 and ensure that the top interior panel 1100 and the top metal sheet 2000 are firmly fixed together.

[0077] The primary function of a car's roof vents is to regulate temperature and ventilate the cabin. Typically, roof vents are attached directly to the vehicle's roof. Multi-purpose vehicles (MPVs) have extra-long roofs, which typically incorporate multiple accessories, such as image recognition, business-class folding monitors, integrated ambient lighting, dual skylights, power air vents, and side curtain airbags. This requires the roof to be strong enough to withstand cracking or deformation during installation and to avoid falling off during side curtain airbag inflation. Because the vents are attached directly to the roof, they not only take up space but also increase the roof's mounting strength requirements. Furthermore, when the side curtain airbags inflate, a direct impact is applied to the vents, which can cause the roof to deform and fall.

[0078] In view of the above, and referring to Figures 29 to 31, in one embodiment of a vehicle ceiling of the present invention, by attaching the exhaust port assembly 300 to the top metal sheet 2000, the installation space of the top interior panel 1100 is saved, the weight load required to be applied to the top interior panel 1100 is reduced, and problems of deformation and detachment of the top interior panel 1100 are improved.

[0079] 29, in one embodiment, the vehicle ceiling further includes an exhaust port housing 310 and a plurality of connecting buckles 320, the exhaust port housing 310 is disposed between the top metal sheet 2000 and the top interior panel 1100, the plurality of connecting buckles 320 are provided on one end of the exhaust port housing 310 facing the top metal sheet 2000, and the exhaust port housing 310 is engaged with the top metal sheet 2000 via the plurality of connecting buckles 320. By directly attaching the exhaust port housing 310 to the top metal sheet 2000, it is possible to save installation space and reduce the load-bearing capacity of the top interior panel 1100.

[0080] 29, 30, and 31, the exhaust port assembly 300 is provided between the top metal sheet 2000 and the top interior panel 1100, and is engaged with the top metal sheet 2000 via a plurality of connecting buckles 320 in the exhaust port housing 310. In one embodiment, the plurality of connecting buckles 320 are evenly arranged on one end of the exhaust port housing 310 facing the top metal sheet 2000, and the top metal sheet 2000 is provided with mounting holes to be engaged with the connecting buckles 320, which are elastic buckles that are inserted into the mounting holes of the top metal sheet 2000 by pressing the connecting buckles 320, and when the pressing force is removed, the connecting buckles 320 return to their original position and are locked into the mounting holes. Specifically, the connecting buckle 320 includes a connecting base 321, a first card 322, and a second card 323. The connecting base 321 is fixedly connected to the exhaust port housing 310. The first card 322 and the second card 323 are arranged opposite the connecting base 321, and the gap between them forms a compressible groove 324. The first card 322 and the second card 323 are provided with protruding step portions 325 that engage with the mounting holes. When the first card 322 and the second card 323 are pressed, they both contract into the groove 324 and are inserted into the mounting holes. When the pressing force is removed, the step portions 325 on the first card 322 and the second card 323 are engaged with the mounting holes of the top metal plate 2000. Preferably, the first card 322 and the second card 323 have a tapered shape, i.e., the end facing the top metal plate 2000 is smaller and the end facing the connecting base 321 is larger. This structure has a certain guiding effect and makes it easy to guide the connecting buckle 320 to be inserted into the mounting hole of the top metal plate 2000. The connecting buckle 320 is fixedly connected to the air outlet housing 310. For example, a buckle base, shown as a second buckle base 330, is provided on the top of the air outlet housing 310. The second buckle base 330 is injection molded integrally with the air outlet housing 310. The second buckle base 330 is provided with a sliding groove 331, and the connecting base 321 of the connecting buckle 320 slides into the sliding groove 331 for tight fit.Of course, other methods may be used to fasten the connecting buckle 320 to the exhaust port housing 310 as long as the strength of the connection between the connecting buckle 320 and the exhaust port housing 310 can be ensured. To ensure the mounting strength of the exhaust port assembly 300, the connecting buckle 320 is a metal buckle.

[0081] 29 , in one embodiment, the exhaust end of the air outlet housing 310 is flexibly connected to the top interior panel 1100, ensuring a secure crimping fit between the two and accommodating Z-direction tolerances through compression, preventing airflow obstruction, avoiding misalignment caused by a rigid connection, and improving assembly accuracy. Specifically, the top interior panel 1100 has a cutout region 210 corresponding to the air outlet housing 210, and an elastic seal member 350 is provided on the edge of the cutout region 210 facing the air outlet housing 210. Furthermore, an air outlet panel 340, also known as an ambient light panel, is provided between the air outlet housing 310 and the top interior panel 1100. This panel 340 is used to secure the air outlet housing 310 and to attach ambient lighting. An air outlet panel 340 is fixedly attached to the edge of the cutout area 210, and an elastic sealing member 350 is provided on the side of the air outlet panel 340 facing the air outlet housing 310. The air outlet panel 340 presses against the elastic sealing member 350 to further secure the air outlet assembly on the one hand and to act as a seal to prevent uncontrolled airflow from the inside of the air outlet assembly 300 on the other hand. The elastic sealing member 350 may be a sealing sponge, which is disposed around the periphery of the air outlet end of the air outlet housing 310. The elastic sealing member 350 may be replaced with another sealing member having the same function, such as a rubber gasket. During the assembly process, first, the exhaust port assembly 300 is fastened to the top sheet metal 2000 using the connecting buckle 320, the exhaust port panel 340 is fixed to the top interior panel 1100, and the elastic sealing member 350 is fixed to the exhaust port panel 340; then, the top interior panel 1100 is attached to the top sheet metal 2000, and the elastic sealing member 350 presses against the exhaust port housing 310 to fix the exhaust port assembly.

[0082] 29 , in one embodiment, the air outlet housing 310 includes a first air outlet duct 311 and a second air outlet duct 312, which are symmetrically arranged and connected at an air outlet end. The intake ends of the first air outlet duct 311 and the second air outlet duct 312 are both connected to a main air intake duct (not shown). Air blown out from the air conditioner flows from the main air intake duct to the first air outlet duct 311 and the second air outlet duct 312. Because the first air outlet duct 311 and the second air outlet duct 312 are connected at the air outlet end, the air blown out from the first air outlet duct 311 and the second air outlet duct 312 in different directions intersect and partially cancel each other out at the air outlet end. Ultimately, the larger volume of air determines the overall air direction of the air outlet assembly 300. The air volume in the first exhaust duct 311 and the second exhaust duct 312 may be adjusted by controlling the air guide assembly in the main intake duct with the control assembly. Preferably, both the first exhaust duct 311 and the second exhaust duct 312 are provided with an outlet blade 313 and an outlet motor 314 for controlling the rotation of the outlet blade 313, and the outlet motor 314 is connected to the control assembly to adjust the outlet blade 313 through the control assembly, thereby adjusting the air direction in the first exhaust duct 311 and the second exhaust duct 312.
