Description

Technical Field

[0001] The utility model relates to the field of vehicle carpets, in particular to a vehicle sound-insulating and flame-retardant carpet. Background Art

[0002] Carpet is a floor covering made of natural or synthetic fiber materials such as cotton, linen, wool, silk, grass, etc., which is hand-knitted, flocked or woven. Carpets are generally installed in cars and are one of the indispensable car interior parts. Its main function is to block and eliminate the noise transmitted from the bottom of the car to the inside of the car when driving.

[0003] Patent 2021218268212 of the prior art discloses a flame retardant and fireproof car carpet, wherein a plurality of drainage grooves are provided on the upper end of the carpet body, a footrest is provided on the right side of the upper end of the carpet body, an anti-slip pattern is provided on the upper end of the footrest, a left step edge and a right step edge are provided on the left and right ends of the carpet body respectively, the ends of the left step edge and the right step edge close to each other are made of soft material, a storage bag is provided on the left end of the right step edge, and a plurality of anti-slip balls are provided on the lower end of the carpet body. The PVC coating of the upper fireproof layer and the lower fireproof layer can play a fireproof and waterproof effect. In the event of a fire, the magnesium hydroxide in the flame retardant layer decomposes and absorbs a large amount of heat, and at the same time, the high temperature resistant magnesium oxide solid is generated, which will cover the carpet body to isolate the air. The generated water evaporation can absorb a large amount of heat, which can reduce the temperature to below the ignition point of the combustible material, thereby effectively improving the fire retardant effect.

[0004] The above-mentioned products still have the following shortcomings during actual use: since the carpet is light, it is easy to be displaced by being stepped on by feet when it is laid in the car. As a result, the fire-resistant carpet for cars is easy to be displaced during actual use, resulting in a poor user experience. At the same time, noise often comes from the bottom of the car when the car is driving, affecting the driving experience of users in the car. Utility Model Content

[0005] In view of the above defects or deficiencies in the prior art, it is desirable to provide a sound-insulating and flame-retardant carpet for a vehicle.

[0006] According to the technical solution provided in the embodiment of the present application, a car soundproof and flame-retardant carpet is provided, wherein a plurality of guide grooves are dug on the upper surface of the carpet body, a plurality of groups of evenly distributed convex strips are also installed on the upper surface of the carpet body, Velcro strips are installed on both the left and right sides of the bottom layer of the carpet body, a plurality of evenly distributed limiting pads are laid and bonded on the bottom layer of the carpet body, a first assembly piece and a second assembly piece are respectively installed on the left and right ends of the carpet body, a first waterproof layer is laid and bonded on the lower side of the upper surface of the carpet body, a second waterproof layer is laid and bonded on the upper side of the bottom layer of the carpet body, a plurality of convex strips of each group are provided and are distributed side by side, and the guide groove is a concave square groove The convex strip runs through the left and right sides of the upper surface of the carpet body, is semicircular and has a non-slip surface on the surface, the first assembling piece is a convex plate, the second assembling piece is a concave plate, the first assembling piece matches the second assembling piece, the first assembling piece is plugged into the adjacent second assembling piece, the first flame retardant layer is laid and bonded on the lower side of the first waterproof layer, the second flame retardant layer is laid and bonded on the upper side of the second waterproof layer, the first supporting plate is laid and bonded on the lower side of the first flame retardant layer, the second supporting plate is laid and bonded on the upper layer of the second flame retardant layer, the first sound-absorbing fiber layer is laid and bonded on the lower side of the first supporting plate, and the second sound-absorbing fiber layer is laid and bonded on the upper side of the second supporting plate.

[0007] Furthermore, adhesive sound-absorbing cotton is laid between the first sound-absorbing fiber layer and the second sound-absorbing fiber layer.

[0008] Furthermore, a plurality of groups of evenly distributed rubber pads are sandwiched between the first sound-absorbing fiber layer and the second sound-absorbing fiber layer on the upper and lower sides of the sound-absorbing cotton.

[0009] Furthermore, the Velcro strips and the limiting pad columns are in the same horizontal plane, and a plurality of limiting pad columns are laid and bonded between two adjacent Velcro strips.

[0010] Furthermore, a non-slip surface is provided on the side of the limiting pad column that contacts the vehicle floor.

[0011] In summary, the beneficial effects of this application are:

[0012] 1. Through the arrangement of the magic sticky strip and the limiting pad column, the carpet body can be effectively pasted and fixed in the car. At the same time, the limiting pad column supports the carpet body, increases the friction with the plane inside the car, and makes the carpet body not easily displaced by force, thereby ensuring its firm installation and use in the car, and further improving the firm installation and use of the carpet body in the car and the good experience during use; through the arrangement of the first assembly part, the second assembly part, the convex strip and the guide groove, the required number of carpet bodies can be taken according to the actual paving area in the car, and two adjacent carpet bodies can be plugged in through the first assembly part and the second assembly part. The carpet body is easy to disassemble and assemble, and the practical performance is improved. Through the arrangement of the convex strip and the guide groove, the convex strip plays an anti-slip role, avoiding the user from sliding due to the wet soles when entering the car on rainy days. The guide groove collects foreign matter or dirty water on the carpet body, which is convenient for subsequent cleaning, and the practical performance is improved.

[0013] 2. Through the arrangement of the first waterproof layer, the first flame retardant layer, the first support plate, the first sound-absorbing fiber layer, the sound-absorbing cotton, the rubber pad, the second sound-absorbing fiber layer, the second support plate, the second flame retardant layer and the second waterproof layer, the waterproof layer can make the carpet body have good waterproof properties, and the flame retardant layer makes the carpet body not easy to burn, further improving the safety of the use of the carpet body. The first support plate and the second support plate increase the strength of the carpet body, play a role in reinforcing and strengthening the connection, and extend the service life of the carpet body. The first sound-absorbing fiber layer, the sound-absorbing cotton and the second sound-absorbing fiber layer prevent the noise from continuously propagating into the car, and play a role in reducing noise. The sound-absorbing cotton can absorb noise and allow the noise to continue to attenuate, achieving multiple noise reductions, effectively reducing the noise transmitted from the bottom of the car during driving, and improving the driving experience of users in the car.
