Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a roof accessory fixing structure, roof assembly, and vehicle. Background Technology

[0002] With the increasing multi-functionality of vehicles, the types and quantities of roof accessories are constantly increasing, such as lights, life detectors, microphones, cameras, and other equipment. These accessories are usually modular in design and need to be installed on the roof through a fixed structure to ensure their stability and safety while the vehicle is in motion.

[0003] In related technologies, the fixing structure of the ceiling accessories may interfere with the air curtain due to its installation location. When the air curtain bursts, the fixing structure of the accessories may be impacted. Therefore, it is necessary to ensure that the fixing is secure and to prevent it from falling off due to the impact of the air curtain. Utility Model Content

[0004] In view of this, the present invention provides a roof accessory fixing structure, a roof assembly, and a vehicle to solve the problem that the accessory fixing structure is prone to falling off when subjected to impact.

[0005] In a first aspect, this utility model provides a ceiling accessory fixing structure, comprising:

[0006] The first fastener and the second fastener together form an installation cavity, which is suitable for accommodating ceiling accessories;

[0007] The first fastener is fixedly installed on the second fastener, and the second fastener is suitable for installation on the ceiling body;

[0008] One side of the second fastener canopy body is adapted to be filled with an adhesive layer to connect the second fastener to the canopy body.

[0009] Beneficial effects: To reduce the impact on the roof accessory fixing structure, this embodiment fills the space between the second fixing member and the roof body with an adhesive layer. This adhesive layer effectively bonds the second fixing member to the roof body, preventing gaps between them. This allows less air curtain penetration into the area between the second fixing member and the roof body during air curtain deployment, effectively reducing the impact force of the air curtain on the roof accessory fixing structure and ensuring the stability of the roof accessory during use. Simultaneously, the effective bonding of the adhesive layer improves the overall structure's impact resistance, meeting the protection requirements for the roof accessory during air curtain deployment and ensuring normal function even in extreme situations. This further enhances the reliability of the roof accessory during vehicle operation, reduces potential risks caused by air curtain deployment, and improves in-vehicle safety performance.

[0010] In one alternative embodiment, the second fastener includes:

[0011] Accessory mounting section, suitable for placing ceiling accessories;

[0012] The fixing plate body is arranged around the outer periphery of the accessory mounting part, and the adhesive layer is filled between the fixing plate body and the ceiling body.

[0014] In one alternative embodiment, the second fastener further includes a retaining portion surrounding the outer periphery of the fixing plate body, the retaining portion being adapted to extend from the fixing plate body toward the canopy body.

[0015] Beneficial effects: The enclosure is arranged around the outer periphery of the fixed plate body, and the enclosure is adapted to extend from the fixed plate body towards the ceiling body, thereby forming a cavity in the area enclosed by the fixed plate body and the enclosure to fill the adhesive, ensuring uniform distribution of the adhesive, enhancing the bonding effect, and further improving the bonding strength between the fixed plate body and the ceiling body; at the same time, the design of the enclosure can also block the air curtain, so that when the air curtain bursts, it can intrude less into the area between the fixed plate body and the ceiling body, effectively resisting the impact force when the air curtain bursts.

[0016] In one alternative embodiment, the fixing plate body has at least one overflow hole.

[0017] Beneficial effects: By opening at least one overflow hole in the fixing plate body, it is possible to observe whether there is insufficient adhesive, avoid weak bonding caused by insufficient adhesive, and replenish adhesive in time to ensure bonding effect. On the other hand, the overflow hole allows excess adhesive to be discharged smoothly, preventing adhesive accumulation that could lead to uneven bonding, ensuring that the adhesive layer thickness is moderate, thereby further optimizing the bonding quality between the fixing plate body and the ceiling body, preventing adhesive accumulation from affecting the installation effect, and ensuring uniform and firm bonding.

[0018] In one alternative embodiment, the second fastener further includes a reinforcing rib disposed on the side of the fixing plate body facing the ceiling body, and the reinforcing rib connects the enclosure portion and the accessory mounting portion.

[0019] Beneficial effects: The reinforcing ribs connect the enclosure section and the accessory installation section, forming a stable support structure, enhancing the overall rigidity of the fixing plate body, effectively dispersing the impact force when the air curtain bursts, ensuring the stability of the roof accessories under extreme working conditions, and further extending their service life.

[0046] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0047] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0048] According to an embodiment of the present invention, in one aspect, a ceiling accessory fixing structure is provided, comprising:

[0049] The first fixing member 1 and the second fixing member 2 together form an installation cavity 3, which is suitable for accommodating ceiling accessories;

[0050] The first fastener 1 is fixedly installed on the second fastener 2, and the second fastener 2 is suitable for installation on the ceiling body;

[0051] The side of the second fastener 2 facing the ceiling body is adapted to be filled with an adhesive layer to connect the second fastener 2 to the ceiling body.

[0052] The first fixing member 1 and the second fixing member 2 enclose and form a mounting cavity 3, which is suitable for accommodating the ceiling accessory. In this embodiment, the ceiling accessory may include a life detector.

[0053] By fixing the ceiling accessories inside the installation cavity, it is convenient to use the first fixing member 1 and the second fixing member 2 to surround and fix the ceiling accessories, ensuring that they are not easily moved during use and making it easy to fix the ceiling accessories to the ceiling body.

[0054] In this embodiment, the first fixing member 1 is fixedly installed on the second fixing member 2. During the specific installation process, the ceiling accessory can be placed in the installation cavity 3 first, and then the first fixing member 1 and the second fixing member 2 can be combined to ensure that the ceiling accessory is stably installed in the installation cavity 3 formed by the first fixing member 1 and the second fixing member 2. This makes the first fixing member 1, the ceiling accessory and the second fixing member 2 form an integral structure, which effectively improves the installation stability of the ceiling accessory, facilitates pre-assembly and improves installation efficiency.

[0055] After assembling the first fastener 1, the ceiling accessory and the second fastener 2, the second fastener 2 is further installed and fixed to the ceiling body to achieve a stable installation of the overall structure on the ceiling body.

[0056] Due to the limited space in a vehicle's roof, especially since the air curtain requires a significant amount of space on the roof side beams, interference between the roof accessories and the air curtain can cause impact to the fixing structure of the roof accessories when the air curtain deploys, thus affecting the stability of the roof accessories. To reduce the impact on the fixing structure of the roof accessories, this embodiment fills the space between the second fixing member 2 and the roof body with an adhesive layer. This adhesive layer effectively bonds the second fixing member 2 to the roof body, preventing gaps between them. This allows less air curtain penetration into the area between the second fixing member 2 and the roof body when the air curtain deploys, effectively reducing the impact force of the air curtain on the fixing structure of the roof accessories and ensuring their stability during use. Simultaneously, the effective bonding of the adhesive layer improves the overall structure's impact resistance, meeting the protection requirements for the roof accessories when the air curtain deploys, ensuring normal function even in extreme situations. This further enhances the reliability of the roof accessories during vehicle operation, reduces potential risks caused by air curtain deployment, and improves in-vehicle safety performance.

[0057] In some embodiments, the second fastener 2 includes:

[0058] Accessory mounting section 20 is suitable for mounting ceiling accessories;

[0059] The fixing plate body 21 is arranged around the outer periphery of the accessory mounting part 20, and the adhesive layer is filled between the fixing plate body 21 and the ceiling body.

[0060] The second fastener 2 includes an accessory mounting part 20 suitable for placing the roof accessory, thereby firmly positioning the roof accessory and ensuring that it does not shift during vehicle operation, further improving the stability of the overall structure.

[0061] The fixing plate body 21 is arranged around the outer periphery of the accessory mounting part 20, and ensures that the adhesive layer is filled between the fixing plate body 21 and the roof body, thereby increasing the coating area of ​​the adhesive layer, enhancing the bonding effect, ensuring that the fixing plate body 21 and the roof body are tightly bonded, further reducing the impact of the air curtain bursting, improving the overall impact resistance of the roof accessory, and ensuring the safety of the vehicle interior.

[0062] In some embodiments, the accessory mounting portion 20 has an accessory through hole 27, which allows the ceiling accessory to at least partially pass through the accessory mounting portion 20, preventing the second fastener 2 from obstructing the view and facilitating the function of the ceiling accessory. Furthermore, on the side of the fixing plate body 21 facing away from the first fastener 1, the fixing plate body 21 also forms a clearance portion 28 around the accessory mounting portion 20. The clearance portion 28 provides clearance space for the working area of ​​the ceiling accessory, preventing the ceiling accessory from being unable to work properly due to space limitations.

[0063] In some embodiments, the second fastener 2 further includes a barrier portion 22, which is disposed around the outer periphery of the fixing plate body 21, and the barrier portion 22 is adapted to extend from the fixing plate body 21 toward the side of the ceiling body.

[0064] The enclosure portion 22 is disposed around the outer periphery of the fixed plate body 21, and the enclosure portion 22 is adapted to extend from the fixed plate body 21 toward the ceiling body, thereby forming a receiving cavity in the area enclosed by the fixed plate body 21 and the enclosure portion 22, so as to fill the adhesive, ensure the adhesive is evenly distributed, enhance the bonding effect, and further improve the bonding strength between the fixed plate body 21 and the ceiling body; at the same time, the design of the enclosure portion 22 can also block the air curtain, so that when the air curtain bursts, it can invade less of the area between the fixed plate body 21 and the ceiling body, effectively resisting the impact force when the air curtain bursts.

[0065] In some embodiments, the fixing plate body 21 has at least one overflow hole 24.

[0066] By creating at least one overflow hole 24 in the fixing plate body 21, it is possible to observe whether there is insufficient adhesive, avoiding weak adhesion caused by insufficient adhesive, and replenishing adhesive in time to ensure bonding effect. On the other hand, the overflow hole 24 allows excess adhesive to drain smoothly, preventing adhesive accumulation that could lead to uneven adhesion, ensuring a moderate adhesive layer thickness, thereby further optimizing the bonding quality between the fixing plate body 21 and the ceiling body, preventing adhesive accumulation from affecting the installation effect, and ensuring uniform and firm adhesion. This improves the bonding strength between the fixing plate body 21 and the ceiling body, further optimizing the impact resistance of the overall structure.

[0067] In some embodiments, the second fastener 2 further includes a reinforcing rib 23 disposed on the side of the fixing plate body 21 facing the ceiling body, and the reinforcing rib 23 is connected between the enclosure portion 22 and the accessory mounting portion 20.

[0068] The reinforcing rib 23 connects the enclosure part 22 and the accessory installation part, forming a stable support structure, enhancing the overall rigidity of the fixing plate body 21, effectively dispersing the impact force when the air curtain bursts, ensuring the stability of the roof accessory under extreme working conditions, and further extending its service life. The reinforcing rib 23 also improves the deformation resistance of the fixing plate body 21, reducing the risk of structural deformation caused by the bursting of the air curtain, and ensuring that the roof accessory can maintain normal function under various working conditions.

[0069] In some embodiments, one of the first fixing member 1 and the second fixing member 2 is provided with a buckle 12, and the other is formed with a slot 29 adapted to engage with the buckle 12.

[0070] The cooperation between the buckle 12 and the slot 29 facilitates the pre-installation of the first fixing member 1 and the second fixing member 2, which serves as positioning and initial fixation, making it easier to use fasteners for precise fixation later, improving installation efficiency, and ensuring a firm and reliable connection to prevent loosening caused by vibration or impact.

[0071] In this embodiment, the first fixing member 1 is provided with two buckles 12, which are located on its two sides and symmetrically distributed. The second fixing member 2 forms two corresponding slots 29 to ensure that the force is evenly distributed on both sides, enhance the connection stability, and prevent displacement during installation.

[0072] In some embodiments, the first fastener 1 has a fastener through hole 11 and the second fastener 2 has a fastener mounting hole 26. The fastener through hole 11 and the fastener mounting hole 26 are aligned and adapted to be connected by fasteners.

[0073] Since the first fixing member 1 and the second fixing member 2 are separate structures, the first fixing member 1 and the second fixing member 2 can be pre-installed easily through the cooperation of the buckle 12 and the slot 29. Then, through the precise alignment of the fastener through hole 11 and the fastener mounting hole 26, the fastener is finally fixed to ensure a tight connection and further improve the stability of the overall structure.

[0074] The connection method between the first fastener 1 and the second fastener 2 can ensure the firmness of their installation, effectively resist external impact, prevent the first fastener 1 and the second fastener 2 from loosening, and thus prevent the ceiling accessories from falling off.

[0075] In some embodiments, combined with Figure 2 As shown, the second fastener 2 also includes a support rib 25, which is disposed inside the area enclosed by the accessory mounting part 20, and the support rib 25 is suitable for supporting the ceiling accessory.

[0076] In some embodiments, the first fastener 1 further includes a pressing rib 13, which is disposed on the side of the first fastener 1 facing the second fastener 2, and the pressing rib 13 is adapted to press the ceiling accessory.

[0077] The support rib 25 is disposed inside the area enclosed by the accessory mounting part 20 and is adapted to support the ceiling accessory. Specifically, the support rib 25 is disposed on the side of the second fixing member 2 facing the first fixing member 1. By pressing the ceiling accessory between the support rib 25 and the pressing rib 13, a stable installation is formed, effectively preventing the ceiling accessory from shifting under vibration or impact, and ensuring its stability under various complex working conditions.

[0078] According to an embodiment of the present invention, in another aspect, a roof assembly is also provided, comprising:

[0079] The ceiling itself;

[0080] And the ceiling accessory fixing structure as described above, which is installed on the ceiling body;
