[0031] Decorative flame-retardant boards are usually installed on the instrument panel, door panel, and ceiling in the car interior and need to be directly fixed to the vehicle body. For example, for the decorative board installed on the door, it is necessary to directly use bolts or glue to fix it inside the door panel, and then cover the decorative board or leather material on the surface of the flame-retardant board. Since the decorative flame-retardant board is usually soft and loose, when fixed with screws or glue, it is likely to fall off after the car has been driving bumpily for a long time.

[0032] Based on this, it is possible to improve the problem in the related technology that the decorative flame-retardant board is usually soft and loose, and when fixed with screws or glue, it is likely to fall off after the car has been driving bumpily for a long time.

[0033] Please refer to Figures 1 - 8 , a flame-retardant board for interior decoration of a vehicle, including a flame-retardant board 1. A plurality of installation components 3 are installed at the outer end of the flame-retardant board 1. A fixing component 4 is arranged inside the installation component 3. A connecting component 2 is arranged inside the fixing component 4. The fixing component 4 includes a fixing sleeve 41. Three slots 42 are opened inside the fixing sleeve 41. The three slots 42 communicate with each other. A fixing block 43 is fixedly connected to the inner side wall of the slot 42. The fixing block 43 is arranged in a right-angled trapezoid shape. The connecting component 2 includes a plug pin 29. Three elastic pieces 22 are arranged at the outer end of the plug pin 29. The elastic pieces 22 are arranged in an arc shape and bend away from the plug pin 29. A contact block 23 is fixedly connected to the outer end of each of the three elastic pieces 22. A plurality of equally spaced teeth are arranged at the outer ends of the contact block 23 and the fixing block 43. The contact block 23 abuts against the fixing block 43.

[0034] The flame retardant board 1 is composed of phenolic cotton 13, a sound insulation layer 14, two aluminum foils 11 and multiple adhesive layers 12. The phenolic cotton 13 and the sound insulation layer 14 are both located between the two aluminum foils 11, and the phenolic cotton 13 and the sound insulation layer 14 are connected by the adhesive layer 12.

[0035] The decoration part of an automobile is usually divided into an internal flame retardant layer and an external decoration layer. The flame retardant layer needs to be directly fixed to the vehicle body. The device in this solution is mainly used as the flame retardant layer in the interior decoration of an automobile. Multiple mounting components 3 are installed on the flame retardant board 1, while the fixing component 4 needs to be installed on the vehicle body in advance. The connecting component 2 is mainly used to insert into the fixing sleeve 41 to fix the mounting component 3 between the connecting component 2 and the fixing component 4, thus achieving the purpose of fixing the flame retardant board 1.

[0036] By providing the mounting component 3 on the flame retardant board 1, the main mounting sleeve 31 and the sub-mounting sleeve 33 are mutually clamped and installed on the flame retardant board 1 through tooth marks. The fixing component 4 is pre-welded on the vehicle body. During installation, the sub-mounting sleeve 33 is sleeved on the outer periphery of the fixing sleeve 41. Three slots 42 are provided inside the fixing sleeve 41, and these three slots 42 communicate with each other. At the same time, fixing blocks 43 are fixed on the inner side wall of the slot 42. The fixing blocks 43 are arranged in a right trapezoid shape, and the surface of the fixing block 43 in contact with the abutting block 23 is an inclined surface. A metal base is fixed at the bottom of the fixing sleeve 41. By welding this base to the vehicle body, the fixing component 4 can be installed on the vehicle body in advance. It is worth mentioning that the installation position of the fixing component 4 needs to be located in advance so that it can correspond to the multiple mounting components 3 on the flame retardant board 1 one by one. Then, a pin 29 is used to penetrate the slot 42, and the elastic piece 22 will enter the slot 42, so that the abutting block 23 on the elastic piece 22 abuts against the fixing block 43. Since dense teeth are provided on both the fixing block 43 and the abutting block 23, the teeth of the fixing block 43 and the abutting block 23 are mutually clamped together, and the flame retardant board can be fixed on the vehicle body. Since the contact surface between the fixing block 43 and the abutting block 23 is inclined, the more the user presses downwards, the tighter the fixing block 43 and the abutting block 23 can be clamped. During installation, no other tools such as a screwdriver are needed, and the connecting component 2 can be directly pressed, improving the installation convenience. By clamping and connecting through teeth, the installation firmness can also be improved, and it is not easy to fall off after long-term use.

[0037] Among them, the flame-retardant board 1 is mainly composed of an aluminum foil 11, an adhesive layer 12, phenolic cotton 13 and a sound insulation layer 14. The aluminum foil 11 is located at the outermost part on both sides, sandwiching the phenolic cotton 13 and the sound insulation layer 14 in the middle. The aluminum foil 11, the phenolic cotton 13 and the sound insulation layer 14 are connected by the adhesive layer 12. The adhesive layer 12 is mainly composed of glue. The aluminum foil 11 on the outermost layer can play a role in heat insulation. The phenolic cotton 13, also known as phenolic resin impregnated cotton, is an insulating material made by impregnating cotton cloth or cotton yarn with phenolic resin and pressing, which has good flame retardant and high temperature resistance performance. The sound insulation layer 14 is made of polyester fiber sound insulation cotton, formed in the shape of cocoon cotton after high-tech hot pressing, and the sound absorption coefficient reaches 0.94 in the noise range of 125 - 4000HZ. The aluminum foil 11, the adhesive layer 12, the phenolic cotton 13 and the sound insulation layer 14 are formed by a molding process, so that it can have good flame retardant and sound absorption characteristics.

[0038] Optionally, in some embodiments, please refer to Figures 3 - 5 , the installation component 3 includes a main installation sleeve 31 and a sub-installation sleeve 33. The main installation sleeve 31 penetrates through the flame-retardant board 1. Tooth marks that match each other are provided on the inner wall of the main installation sleeve 31 and the outer periphery of the sub-installation sleeve 33. The sub-installation sleeve 33 and the main installation sleeve 31 are connected through the tooth marks.

[0039] A first cover plate 32 is fixedly connected to the outer end of the main installation sleeve 31, and a second cover plate 34 is fixedly connected to the outer end of the sub-installation sleeve 33. A plurality of friction strips 35 are fixedly connected to the sides of the first cover plate 32 and the second cover plate 34 that are close to each other. The friction strips 35 are made of rubber material. The first cover plate 32 and the second cover plate 34 are respectively located on both sides of the flame-retardant board 1, and the friction strips 35 are in contact with the outer end of the flame-retardant board 1.

[0040] The installation component 3 in this solution is mainly used to be installed on the flame-retardant board 1. Since the connection component 2 needs to penetrate through the flame-retardant board 1, the installation component 3 is installed in the through hole opened on the flame-retardant board 1, which can protect the through hole and prevent the materials inside the flame-retardant board 1 from running out. A first cover plate 32 and a second cover plate 34 are respectively fixed on the outer sides of the main installation sleeve 31 and the sub-installation sleeve 33. A plurality of friction strips 35 made of rubber are installed on both the first cover plate 32 and the second cover plate 34. After the main installation sleeve 31 penetrates through the through hole opened on the flame-retardant board 1, and then the sub-installation sleeve 33 is inserted into the main installation sleeve 31, the second cover plate 34 and the first cover plate 32 can be respectively located on both sides of the flame-retardant board 1, pressing the edge of the through hole. Then, through the frictional force generated by the contact between the friction strips 35 and the flame-retardant board 1, the shaking of the installation component 3 can be reduced and its stability can be improved. At the same time, the main installation sleeve 31 and the sub-installation sleeve 33 are connected by being clamped together through the tooth marks provided on the outer periphery of the sub-installation sleeve 33 and the inner side wall of the main installation sleeve 31, which is the same as the fixing principle of the abutting block 23 and the fixing block 43. By controlling the depth of the sub-installation sleeve 33 inserted into the main installation sleeve 31, it can adapt to flame-retardant boards 1 of different thicknesses.

[0041] Optionally, in some embodiments, refer to Figure 6 and Figure 8 , the connecting component 2 further includes a plurality of mounting blocks 24. Three mounting grooves 210 are formed at the outer end of the plug pin 29. The elastic pieces 22 are mounted in the mounting grooves 210 through the mounting blocks 24, and the elastic pieces 22 are adapted to the slots 42.

[0042] The top end of the plug pin 29 is fixedly connected with a top cover 21. The bottom end of the top cover 21 is fixedly connected with a plurality of extension blocks 25. A plurality of folding grooves 26 are formed on both sides of each extension block 25.

[0043] The connecting component 2 further includes three telescopic springs 27. Connecting blocks 28 are fixedly connected to both the elastic pieces 22 and the inner side wall of the mounting groove 210. The telescopic springs 27 are fixedly installed between the two connecting blocks 28.

[0044] In this solution, the top of the plug pin 29 is fixed with a top cover 21. A plurality of extension blocks 25 are fixed on the outer side of the bottom end of the top cover 21. A plurality of folding grooves 26 are formed on both sides of each extension block 25. When the plug pin 29 is inserted into the slot 42, the extension block 25 will abut against the cover piece 32. When the thickness of the flame retardant board 1 is relatively thick, the secondary mounting sleeve 33 is not completely inserted into the main mounting sleeve 31, and the overall height of the mounting component 3 becomes higher. At this time, some of the extension block 25 can be partially broken off through the folding groove 26, so that the plug pin 29 can continue to be completely inserted into the slot 42, and the abutting block 23 can abut against the inclined surface of the fixed block 43 deeper.

[0045] Three mounting grooves 210 are formed at the outer end of the plug pin 29, and three elastic pieces 22 are mounted in the mounting grooves 210. Both ends of each elastic piece 22 are fixed inside the mounting groove 210 through the mounting block 24. The elastic pieces 22 are made of elastic plastic. Connecting blocks 28 are fixedly arranged at the concave part of the elastic piece 22 and inside the mounting groove 210. A telescopic spring 27 is fixed between the two connecting blocks 28. Through its own elastic force, when the abutting block 23 on the elastic piece 22 abuts against the fixed block 43, the telescopic spring 27 can push the elastic piece 22 outwards, so that the abutting block 23 and the fixed block 43 can abut more tightly, improving the connection strength.

[0046] Working principle: When using this device, it is first necessary to install the fixing component 4 on the vehicle body in advance. A metal base is fixed at the bottom of the fixing sleeve 41, and this base is welded to the vehicle body. The installation component 3 is installed in the through hole opened in the flame retardant board 1. The flame retardant board 1 is mainly composed of an aluminum foil 11, an adhesive layer 12, a phenolic cotton 13 and a sound insulation layer 14. During installation, the secondary installation sleeve 33 is sleeved on the outer periphery of the fixing sleeve 41, and then the pin 29 is passed through the slot 42, and the elastic piece 22 will enter the slot 42, so that the abutting block 23 on the elastic piece 22 abuts against the fixed block 43. Since dense teeth are provided on both the fixed block 43 and the abutting block 23, the teeth of the fixed block 43 and the abutting block 23 are engaged with each other, and the flame retardant board can be fixed on the vehicle body. Connecting blocks 28 are fixed in the concave portion of the elastic piece 22 and inside the installation groove 210, and a telescopic spring 27 is fixed between the two connecting blocks 28. The elastic piece 22 is pushed outwards, so that the abutting block 23 and the fixed block 43 can abut more closely, improving the connection strength.

[0047] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
