Description

Technical Field

[0001] This utility model belongs to the field of carpet technology, specifically relating to a flame-retardant and sound-insulating carpet for vehicles. Background Technology

[0002] Currently, car carpets are an indispensable part of car interiors. However, existing car carpets do not have an inflatable support function and rely solely on the thickness and hardness of their material to maintain their shape. This makes them prone to dents and wrinkles. Furthermore, most existing car carpets have a flat surface, which limits their anti-slip performance. Especially during sudden braking or acceleration while driving, shoes can easily slide on the carpet surface, increasing safety hazards. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a flame-retardant and sound-insulating carpet for vehicles.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a flame-retardant and sound-insulating carpet for vehicles, comprising a carpet surface layer, a sound-insulating layer one bonded to the underside of the carpet surface layer, a flame-retardant layer one bonded to the underside of the sound-insulating layer one, a support layer installed below the flame-retardant layer one, and a plurality of spherical protrusions installed on the upper side of the carpet surface layer, wherein spherical grooves are formed at the positions of the carpet surface layer on the outer periphery of the plurality of spherical protrusions, and the spherical protrusions and adjacent spherical grooves form a wavy line structure.

[0005] Preferably, the side of the support layer is provided with two protrusions and two grooves, which are formed on the side of the support layer opposite to the protrusions. The protrusions and grooves cooperate with each other.

[0006] Preferably, the support layer has a cavity 1 inside, and the support layer has a groove 2 on the side adjacent to the protrusion 1. A miniature air pump is detachably connected in the groove 2. A through hole 1 is opened at the bottom of the groove 2. The through hole 1 communicates with the cavity 1, and the output end of the miniature air pump is located in the through hole 1.

[0007] Preferably, two protrusions are installed on the side of the support layer opposite to the groove, and two grooves are formed on the side of the support layer on the same side as the groove, with the protrusions and grooves cooperating.

[0008] Preferably, the support layer has a through hole two on the same side as the groove, the through hole two communicates with the cavity one, and a plug one or a connecting pipe one is detachably connected to the outer periphery of the through hole two.

[0009] Preferably, the support layer has a through hole three on the same side as the protrusion, the through hole three communicates with the cavity one, and the outer periphery of the through hole three is detachably connected to a plug two or a connecting pipe one.

[0010] Preferably, the support layer has a through hole four on the same side as the protrusion two, the through hole four communicates with the cavity one, and a plug three or a connecting pipe two can be detachably connected to the outer periphery of the through hole four.

[0011] Preferably, the support layer has a through hole five on the same side as the groove three, the through hole five communicates with the cavity one, and a plug four or a connecting pipe two can be detachably connected to the outer periphery of the through hole five.

[0012] Preferably, a second flame-retardant layer is bonded to the bottom of the support layer, and a second sound-insulating layer is bonded to the bottom of the second flame-retardant layer.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] (1) The existing car carpets are mostly flat, while this utility model has multiple spherical protrusions on the carpet surface layer, and spherical grooves are opened on the outer periphery of the spherical protrusions at the position of the carpet surface layer. The two form a wave line structure, which not only increases the friction between the carpet surface and the shoe sole, effectively preventing slipping, but also cushions the foot pressure to a certain extent and improves the comfort of stepping.

[0015] (2) Existing car carpets rely solely on the thickness and hardness of their own material to maintain their shape. However, this utility model uses a micro air pump to allow gas to enter the cavity through the through hole one, and then uses connecting pipe one and connecting pipe two to make the support layer of the entire carpet expand synchronously. This can effectively ensure the flatness and stability of the carpet during use, adapt to different car floor conditions, extend the service life of the carpet, improve the user experience, and avoid carpet dents, wrinkles, and other phenomena.

[0016] (3) The double-layer flame-retardant design is adopted. Flame-retardant layer one and flame-retardant layer two are respectively bonded to the top and bottom of the support layer, which can effectively reduce the risk of fire inside the vehicle and ensure passenger safety.

[0017] (4) The first sound insulation layer is bonded above the first flame retardant layer, and the second sound insulation layer is bonded below the second flame retardant layer. This can significantly reduce external noise and engine noise entering the vehicle, creating a quiet and comfortable driving environment. Attached Figure Description

[0029] like Figures 1-4 As shown, two protrusions 9 are installed on the side of the support layer 4, and two grooves 12 are opened on the side of the support layer 4 opposite to the protrusions 9. The protrusions 9 and the grooves 12 are engaged.

[0030] like Figures 1-4 As shown, the support layer 4 has a cavity 1 inside, and the support layer 4 has a groove 2 on the side adjacent to the protrusion 9. A miniature air pump 10 is detachably connected in the groove 2. A through hole 1 is opened at the bottom of the groove 2, which communicates with the cavity 1, and the output end of the miniature air pump 10 is located in the through hole 1.

[0031] like Figures 1-4As shown, two protrusions 13 are installed on the side of the support layer 4 opposite to the groove 2, and two grooves 3 are opened on the side of the support layer 4 on the same side as the groove 2, with the protrusions 13 and grooves 3 cooperating.

[0032] like Figures 1-4 As shown, a through hole 2 is provided on the side of the support layer 4 on the same side as the groove 12. The through hole 2 communicates with the cavity 1. A plug 7 or a connecting pipe 1 is detachably connected to the outer periphery of the through hole 2.

[0033] like Figures 1-4 As shown, the support layer 4 and the protrusion 9 are on the same side with a through hole 3. The through hole 3 communicates with the cavity 1. A plug 2 or a connecting pipe 1 can be detachably connected to the outer periphery of the through hole 3.

A plug four or a connecting pipe two can be detachably connected to the outer periphery of the through hole five.

[0036] like Figures 1-4 As shown, a flame-retardant layer 5 is bonded below the support layer 4, and a sound-insulating layer 6 is bonded below the flame-retardant layer 5.

[0037] In this utility model, the flame-retardant layer 3 and the flame-retardant layer 5 are made of existing flame-retardant polyester fiber, the carpet layer 1 is made of existing polypropylene fiber, and the sound insulation layer 2 and the sound insulation layer 6 are made of existing polyester fiber cotton.
