The objects, features and advantages of the present invention described above will become more apparent from the following detailed description. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The composite soundproof panel assembly 100 according to the first embodiment of the present invention includes a front panel 110, a rear panel 120, and a sound absorbing material 130, as shown in FIGS. 1 to 3.

The front panel 110 is provided on the front of the assembly so as to face a road on which the vehicle travels, and is a substantially rectangular metal structure made of a metal material such as aluminum or steel.

The front panel 110 is bent at a right angle from the end of the front plate 111 and the front plate 111 formed through the plurality of sound absorbing holes 115 on the front side extending to a predetermined length toward the rear panel 120 side. It includes a fitting plate 113.

Here, the fitting plate 113 is shown and described as extending to the rear panel 120 is bent at a right angle from the upper, lower ends of the front plate 111, but is not limited to this of the front plate 111 It may be provided to be bent at approximately right angles from the left and right ends or bent at approximately right angles from the upper, lower and left and right ends of the front plate 111.

The front panel 110 is made of a metal plate, such as aluminum, alloys, steels including the same, and secondary accidents caused by a vehicle that has been separated while minimizing damage and deformation to a sufficient strength when colliding with a vehicle that has left the road while driving a vehicle. It is possible to minimize safety accidents by preventing them, while minimizing yellowing and discoloration in an environment exposed to the outside to maintain the appearance condition for a long time.

In addition, the rear panel 120 is provided on the rear of the assembly facing the residential area corresponding to the opposite side of the road on which the vehicle is driven, and is a substantially rectangular box-shaped resin structure made of a resin material such as reinforced plastic.

The rear panel 120 is at least in the inner space of the rectangular body 121 and the rectangular body 121 on the substantially rectangular parallelepiped whose bottom surface is closed while the front corresponding to the front plate 111 is completely opened to the outside. At least one internal partition 123 is formed to form a plurality of layout spaces in which one sound absorbing material 130 can be disposed.

The inner partition wall 123 extends a predetermined height from the bottom surface of the square body 121 to have the same height as the square body 121, the left and right ends of the inner partition wall 123 is the inner surface of the square body 121 It can be in contact with one another or spaced apart.

The arrangement space divided by the inner partition wall 123 in the inner space of the rectangular body 121 is provided with a plurality of support ribs 125 are formed to protrude a certain height from the bottom surface to support the sound absorbing material 130, In addition, the support ribs 125 are preferably provided at a height relatively lower than the height of the inner partition 123.

Here, the support rib 125 is illustrated and described as being formed in a single-sided cross-section on the rectangular body 121 to be parallel to the inner partition 123, but may be formed in a lattice shape when the rectangular body 121 is formed.

In addition, the inner side of the rectangular body 121 is provided with a fitting rib 127 to form a fitting groove (127a) is formed to protrude a certain height from the bottom surface is inserted into the fitting plate of the front panel.

Since the rear panel 110 is made of a resin board such as plastic, it is easy to change the design of the internal structures such as the inner partition 123 and the support ribs 125 for optimal sound absorption and sound insulation design. It is possible to improve sound absorbing and soundproofing performance by introducing soundproof design, and it is easy to install in the field and improve workability during construction because it has a relatively light structure compared to the whole assembly made of metal material. .

Accordingly, the operation of manufacturing the composite soundproof panel by coupling the front panel 110 and the rear panel 120 to each other is first in contact with the end of the support rib 125 formed in the arrangement space of the rear panel 120. The sound absorbing material 130 is disposed to be.

In this state, the front panel 110 in accordance with the fitting groove 127a formed between the fitting rib 127 formed on the square body 121 of the rear panel 120 and the inner surface of the square body 121. When the fitting plate 113 is inserted, the fitting plate 113 is forcibly fitted into the fitting groove 127a and assembled with each other.

At the same time, the front panel 110 and the rear panel 120 are integrated with each other with the sound absorbing material 130 interposed therebetween by frictional forces between the fitting ribs 127 and the inner surface of the quadrangular body, which are in contact with both sides of the fitting plate 113. Assembly is complete.

4 is an assembly view showing a composite soundproof panel assembly according to a second embodiment of the present invention, wherein the square mome 121 has an inner partition on the upper and lower sides where the sound absorbing material 130 is disposed. By forming the cavity 135 in which no sound absorbing material is disposed, the sound absorbing material is absorbed and removed by the sound absorbing material 130 at the same time as the sound absorbing material is absorbed through the sound absorbing hole 115 formed in the front plate 111. It can be removed by entering the cavity 135 through).

In addition, the front plate 111 is formed so that the surface of the front plate 111 corresponding to the cavity 135 protrudes relatively higher than the surface of the front plate 111 in contact with the sound absorbing material 130 is formed stepped. Although the groove portion 119 is formed on the surface of the recessed portion 119 to enlarge the internal space of the cavity 135 to improve and reduce the noise reduction effect, but is not limited to this, the front plate 111 The surface of) may be provided in a plane to have the same height from the bottom surface of the square body.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
