DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] according to Figure 1 , 2 As shown in , 3, 4, 5, 6, 7, and 8, this embodiment provides a car carpet with a strong sound insulation effect, comprising an upper carpet surface 1 and a lower carpet surface 3, and a sound absorbing layer 2 is provided between the upper carpet surface 1 and the lower carpet surface 3;

[0029] The upper carpet surface 1 and the sound absorbing layer 2 are detachably connected by a first hook and loop structure, and the sound absorbing layer 2 and the lower carpet surface 3 are detachably connected by a second hook and loop structure; the upper carpet surface 1 is arranged on the upper end surface of the sound absorbing layer 2, and the lower carpet surface 3 is arranged on the lower end surface of the sound absorbing layer 2. The sound absorbing layer 2 arranged between the upper carpet surface 1 and the lower carpet surface 3 can play a role in sound absorption and sound insulation, thereby reducing noise pollution inside the car. Since the upper carpet surface 1 and the lower carpet surface 3 are both fixed to the sound absorbing layer 2 by hook and loop, when replacing or cleaning the old carpet surface on the carpet separately, it is only necessary to disassemble the upper carpet surface 1, the sound absorbing layer 2 and the lower carpet surface 3, and clean or replace the upper carpet surface 1 and the lower carpet surface 3 separately, which is convenient and quick to maintain and has a longer service life.

[0030] In order to prevent the upper carpet surface 1, the sound absorbing layer 2 and the lower carpet surface 3 from separating when the carpet is in use, a first skirt 11 is provided at the edge of the upper carpet surface 1, a second skirt 12 is provided at the edge of the first skirt 11, the second skirt 12 and the upper carpet surface 1 are fixedly connected to the second skirt 12, a third skirt 31 is provided at the edge of the lower carpet surface 3, the third skirt 31 is fixedly connected to the lower carpet surface 3, and the lower end surfaces of the third skirt 31 are detachably connected to the lower end surfaces of the third skirt 31 via a third Velcro structure. When the upper carpet surface 1, the sound absorbing layer 2 and the lower carpet surface 3 are fixed by the Velcro structure, the first skirt 11 and the second skirt 12 at the edge of the upper carpet surface 1 will be wrapped around the outside of the third skirt 31, and the lower end surface of the second skirt 12 is fixed to the lower end surface of the third skirt 31 by the third Velcro structure, so as to prevent dust from falling into the seams between the upper carpet surface 1, the sound absorbing layer 2 and the lower carpet surface 3, and strengthen the connection strength between the seams between the upper carpet surface 1, the sound absorbing layer 2 and the lower carpet surface 3.

[0031] See also Figure 3 and Figure 4 , about the first Velcro structure: the first Velcro structure includes a first velvet surface 13 and a first hook surface 21, the first velvet surface 13 is fixedly connected to the lower end surface of the upper carpet surface 1, the first hook surface 21 is fixedly connected to the upper end surface of the sound-absorbing layer 2, and the first velvet surface 13 is connected to the first hook surface 21 by Velcro. The first Velcro structure fixes the upper carpet surface 1 to the sound-absorbing layer 2 by Velcro connection. When the upper carpet surface 1 covers the upper end of the sound-absorbing layer 2, the first velvet surface 13 at the upper end of the upper carpet surface 1 will be in close contact with the first hook surface 21 at the upper end of the sound-absorbing layer 2, and the hook on the first velvet surface 13 will be embedded in the velvet loop of the first hook surface 21, and a strong friction force and mechanical interlocking effect will be generated through a large number of physical contact points, thereby achieving a stable bond. Since this bonding method mainly relies on the interlocking of physical structures rather than chemical adhesives, the first velvet surface 13 and the first hook surface 21 can be easily opened and closed repeatedly, which is both convenient and durable.

[0032] See also Figure 5 and Figure 6, about the second Velcro structure: the second Velcro structure includes a second hook surface 22 and a third velvet surface 32. The second hook surface 22 is fixedly connected to the lower end surface of the sound absorbing layer 2, and the third velvet surface 32 is fixedly connected to the upper end surface of the lower carpet surface 3. The second hook surface 22 is connected to the third velvet surface 32 by Velcro. The second Velcro structure also adopts a Velcro connection method. When the sound absorbing layer 2 covers the upper end of the lower carpet surface 3, the second hook surface 22 at the lower end of the sound absorbing layer 2 will be tightly attached to the third velvet surface 32 at the upper end of the lower carpet surface 3. The connection between the second hook surface 22 and the third velvet surface 32 will not be described in detail.

[0033] See also Figure 3 , Figure 7 and Figure 8 , about the third Velcro structure: the third Velcro structure includes a fourth velvet surface 33 and a second velvet surface 14, the second velvet surface 14 is fixedly connected to the lower end surface of the third skirt 31, the fourth velvet surface 33 is fixedly connected to the lower end surface of the second skirt 12, and the fourth velvet surface 33 is connected to the second velvet surface 14 by Velcro. Similarly, the third Velcro structure also fixes the second skirt 12 to the third skirt 31 by Velcro connection. When the upper carpet surface 1, the sound absorbing layer 2 and the lower carpet surface 3 are adhered together, the first skirt 11 at the edge of the upper carpet surface 1 will be pressed on the upper end surface of the third skirt 31, and the second skirt 12 will be overlapped on the lower end surface of the third skirt 31. The second velvet surface 14 on the second skirt 12 contacts the fourth velvet surface 33 on the third skirt 31, and the third skirt 31 is fixed to the second skirt 12, so that dust will not fall into the joint between the upper carpet surface 1, the sound absorbing layer 2 and the lower carpet surface 3. The connection between the second velvet surface 14 and the fourth velvet surface 33 will not be described in detail.

[0034] See also Figure 8 More specifically, the upper carpet surface 1 includes a second wear-resistant layer 102 , and a first base layer 101 is provided on a side of the second wear-resistant layer 102 away from the sound-absorbing layer 2 .

[0035] The lower carpet surface 3 includes a second base layer 301, and a third wear-resistant layer 302 is provided on the side of the second base layer 301 away from the sound-absorbing layer 2. The upper carpet surface 1 and the lower carpet surface 3 are both composed of a base layer and a wear-resistant layer. The wear-resistant layer covers the outside of the base layer to increase the service life of the upper carpet surface 1 and the lower carpet surface 3.

[0036] The sound absorbing layer 2 has a plurality of cavities 23 inside. That is to say, the fibers inside the sound absorbing layer 2 are usually soft and dense. This structure causes the sound waves to undergo complex reflection, scattering and absorption processes between the fibers and the cavities 23 after entering the sound absorbing layer 2. The energy of the sound waves is gradually converted into heat energy during these processes, thereby weakening the propagation of the sound waves, thereby achieving the purpose of reducing noise pollution.

[0037] The working principle of the present application: the upper carpet surface 1 and the lower carpet surface 3 are fixed to the sound-absorbing layer 2 by means of Velcro, and the upper carpet surface 1 and the lower carpet surface 3 can be cleaned and replaced separately, and the maintenance is convenient and quick. When the upper carpet surface 1, the sound-absorbing layer 2 and the lower carpet surface 3 are fixed by the Velcro structure, the first skirt 11 and the second skirt 12 at the edge of the upper carpet surface 1 will be wrapped around the outside of the third skirt 31, and the lower end surface of the second skirt 12 is fixed to the lower end surface of the third skirt 31 by the third Velcro structure, so as to prevent dust from falling into the joints of the upper carpet surface 1, the sound-absorbing layer 2 and the lower carpet surface 3, and strengthen the connection strength of the joints of the upper carpet surface 1, the sound-absorbing layer 2 and the lower carpet surface 3.
