[0048] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0049] Reference below Figures 1-8 The sound barrier unit panel 100 according to an embodiment of the present application is described.

[0050] The sound barrier unit panel 100 according to an embodiment of the present application includes a shell 110 and a sound absorbing and insulating component 130 .

[0051] The shell 110 mainly plays the role of protecting the sound-absorbing and insulating component 130. The sound-absorbing and insulating component 130 is arranged on the inner side of the shell 110 to absorb noise. The shell 110 can effectively protect the sound-absorbing and insulating component 130 therein.

[0052] Specifically, the housing 110 is provided with a space for accommodating the sound absorbing and insulating assembly 130. The housing 110 includes a front panel 111 and a back panel 112 facing each other, and a connecting plate 113 connected to the same side of the front panel 111 and the back panel 112 in the height direction.

[0053] For example, the connecting plate 113 can be connected between the bottom end of the panel 111 and the bottom end of the back panel 112, and the two ends of the connecting plate 113 can be fixedly connected to the bottom end of the panel 111 and the bottom end of the back panel 112 respectively, and the panel 111, the connecting plate 113 and the back panel 112 are overall in a "U" shape; the connecting plate 113 can also be connected between the top end of the panel 111 and the top end of the back panel 112, and the two ends of the connecting plate 113 can be fixedly connected to the top end of the panel 111 and the top end of the back panel 112 respectively, and the panel 111, the connecting plate 113 and the back panel 112 are overall in an inverted "U" shape.

[0054] It should be noted that the front panel 111 is a panel portion facing the sound source, and the back panel 112 is a panel portion facing away from the sound source.

[0055] The sound-absorbing and insulating assembly 130 in the embodiment of the present application is arranged in the shell 110 to absorb noise, wherein the panel 111, the back panel 112 and the connecting plate 113 are an integrally formed part, that is, the panel 111, the connecting plate 113 and the back panel 112 can be formed by bending the same plate, which is different from the separate design of the back panel 112 and the panel 111. The sound barrier unit panel 100 of the present application has higher strength, less material consumption during the manufacturing process, and greatly reduces the installation time, thereby improving the production efficiency of the sound barrier unit panel 100.

[0056] According to the sound barrier unit panel 100 of the embodiment of the present application, by constructing the panel 111, the connecting panel 113 and the back panel 112 as an integrally formed part, the production efficiency of the sound barrier unit panel 100 can be greatly improved, the production working hours can be reduced, and the consumption of the panel can be reduced, thereby saving costs to a certain extent.

[0057] In some embodiments of the present application, the connecting plate 113 is disposed between the bottom end of the front panel 111 and the bottom end of the back panel 112, and at least a portion of the sound-absorbing and insulating assembly 130 is fixedly connected to the connecting plate 113. In other words, the two ends of the connecting plate 113 are fixedly connected to the bottom end of the front panel 111 and the bottom end of the back panel 112, respectively, and the front panel 111, the connecting plate 113, and the back panel 112 form a "U" shape as a whole.

[0058] Furthermore, the sound absorbing and insulating component 130 is fixedly engaged with the connecting plate 113. Thus, the sound absorbing and insulating component 130 can be conveniently fixed on the connecting plate 113, ensuring the installation stability of the sound absorbing and insulating component 130.

[0059] Furthermore, the inner side of the connecting plate 113 is provided with a first protrusion 113a and a second protrusion 113b that engage with two opposing side surfaces of the sound-absorbing and insulating assembly 130. Thus, the sound-absorbing and insulating assembly 130 can be engaged between the first protrusion 113a and the second protrusion 113b, which can limit and secure the sound-absorbing and insulating assembly 130.

[0060] In some embodiments of the present application, at least a portion of the connecting plate 113 protrudes upward to form a first protrusion 113a and a second protrusion 113b on the inner side surface of the connecting plate 113 and a first limiting groove 101 and a second limiting groove 102 are formed on the outer side surface of the connecting plate 113, the first limiting groove 101 is opposite to the first protrusion 113a, and the second limiting groove 102 is opposite to the second protrusion 113b.

[0061] According to some embodiments of the present application, the sound barrier unit panel 100 also includes a decoupling rubber pad 171, which is arranged on the outer side of the connecting plate 113 and is provided with a first limiting protrusion 171a and a second limiting protrusion 171b that are respectively engaged with the first limiting groove 101 and the second limiting groove 102.

[0062] It should be noted that not all sound barrier unit panels 100 have decoupling rubber pads 171 on the outer side of the bottom connecting plate 113. Only when the bottom of the current sound barrier unit panel 100 is the ground or a cement board, the bottom connecting plate 113 will be provided with a decoupling rubber pad 171 to reduce the impact force on the sound barrier unit panel 100 and play a buffering role.

[0063] Furthermore, the decoupling rubber pad 171 and the connecting plate 113 are fixed by a first mandrel rivet. Thus, after the decoupling rubber pad 171 and the connecting plate 113 are limited by the first limiting protrusion 171a and the first limiting groove 101, the second limiting protrusion 171b and the second limiting groove 102, they can be fixedly connected by the first mandrel rivet.

[0064] In some embodiments of the present application, the housing 110 further includes a top plate 114, which is fixedly connected to the other end of the panel 111 and the back plate 112 on the same side in the height direction. In some embodiments of the present application, the two ends of the top plate 114 are fixedly connected to the top end of the panel 111 and the top end of the back plate 112, respectively.

[0065] The top plate 114 is fixed to the other end of the panel 111 and the back plate 112 on the same side in the height direction. This facilitates the quick installation of the top plate 114 on the panel 111 and the back plate 112, and when the sound barrier unit panel 100 needs to be inspected or maintained, the top plate 114 can also be quickly removed from the panel 111 and the back plate 112.

[0066] Furthermore, the other ends of the panel 111 and the back panel 112 on the same side in the height direction are bent toward each other to form a first clamping leg 111a and a second clamping leg 112a, and the two ends of the top plate 114 are provided with a first clamping groove 103 and a second clamping groove 104 respectively cooperating with the first clamping leg 111a and the second clamping leg 112a.

[0067] In one embodiment of the present application, the top of the panel 111 and the top of the back panel 112 are bent toward each other to form a first snap-in leg 111a and a second snap-in leg 112a, and the top panel 114 is snap-fitted and fixed to the top of the panel 111 and the top of the back panel 112, thereby improving the installation efficiency of the top panel 114.

[0068] Specifically, the top plate 114 includes a top plate body 114a, a first branch plate 114b, and a second branch plate 114c. The first branch plate 114b and the second branch plate 114c are both formed on the outer surface of the top plate body 114a and extend away from each other. The first branch plate 114b is spaced apart from the top plate body 114a to form a first engaging groove 103, and the second branch plate 114c is spaced apart from the top plate body 114a to form a second engaging groove 104. It should be noted that the free end of the first branch plate 114b is spaced apart from the end of the top plate body 114a near the front panel 111, and the free end of the second branch plate 114c is spaced apart from the end of the top plate body 114a near the back panel 112. This facilitates the top plate body 114a to extend into the inner sides of the first and second engaging legs 111a, 112a, ensuring faster installation.

[0069] Furthermore, a first stopper plate 114d and a second stopper plate 114e are provided at both ends of the top panel body 114a adjacent to the front panel 111 and the back panel 112, respectively affixing to the front panel 111 and the back panel 112. For example, the first stopper plate 114d can affix to the inner side of the front panel 111, and the second stopper plate 114e can affix to the inner side of the back panel 112. This ensures the installation stability of the top panel 114 and prevents it from shaking after being installed on the front panel 111 and the back panel 112.

[0070] In some embodiments of the present application, the sound barrier unit panel 100 also includes a first interlayer rubber pad 172 and a second interlayer rubber pad 173 fixed on the top plate 114, and a third limiting protrusion 172a is provided on the first interlayer rubber pad 172, and a fourth limiting protrusion 173a is provided on the second interlayer rubber pad 173.

[0071] Among them, the third limiting protrusion 172a is opposite to the first limiting groove 101 on the connecting plate 113, and the fourth limiting protrusion 173a is opposite to the second limiting groove 102 on the connecting plate 113. When multiple sound barrier unit panels 100 are stacked together, the third limiting protrusion 172a on the first interlayer rubber pad 172 of the lower sound barrier unit panel 100 can cooperate with the first limiting groove 101 on the connecting plate 113 of the upper sound barrier unit panel 100, and the fourth limiting protrusion 173a on the second interlayer rubber pad 173 of the lower sound barrier unit panel 100 can cooperate with the second limiting groove 102 on the connecting plate 113 of the upper sound barrier unit panel 100.

[0072] In some embodiments of the present application, at least a portion of the first interlayer rubber pad 172 extends into the first engaging groove 103, and at least a portion of the second interlayer rubber pad 173 extends into the second engaging groove 104. The first interlayer rubber pad 172, the first branch plate 114b, and the top plate body 114a are fixed by a second axial rivet, and the second interlayer rubber pad 173, the second branch plate 114c, and the top plate body 114a are fixed by a third axial rivet. Thus, the top plate 114 can be more securely mounted on the front panel 111 and the back panel 112.

[0073] According to some embodiments of the present application, at least a portion of the sound absorbing and insulating assembly 130 is fixedly connected to the top plate 114. This further ensures the installation stability of the sound absorbing and insulating assembly 130.

[0074] Furthermore, the sound-absorbing and insulating assembly 130 is snap-fitted to the top plate 114, making the installation of the sound-absorbing and insulating assembly 130 more convenient. Specifically, a third protrusion 114f and a fourth protrusion 114g are provided on the inner side of the top plate 114. The third protrusion 114f and the fourth protrusion 114g respectively snap-fit ​​with two opposing side surfaces of the sound-absorbing and insulating assembly 130.

[0075] It should be noted that the first and second protrusions 113a, 113b can limit the sound-absorbing and insulation assembly 130 in different directions than the third and fourth protrusions 114f, 114g. For example, the first and second protrusions 113a, 113b can limit the front-to-back movement of the sound-absorbing and insulation assembly 130, while the third and fourth protrusions 114f, 114g can limit the left-to-right movement of the sound-absorbing and insulation assembly 130. This further ensures the installation stability of the sound-absorbing and insulation assembly 130.

[0076] In some embodiments of the present application, the housing 110 further includes a first side panel 115 and a second side panel 116 that are opposite each other. The first side panel 115 is fixed to one end of the same side of the front panel 111 and the back panel 112 in the horizontal direction, and the second side panel 116 is fixed to the other end of the same side of the front panel 111 and the back panel 112 in the horizontal direction. Therefore, the first side panel 115, the front panel 111, the second side panel 116, the back panel 112, the connecting panel 113, and the top panel 114 define a storage space for accommodating the sound-absorbing and insulating assembly 130.

[0077] The first side panel 115 is provided with a first flange 115a and a second flange 115b at both ends adjacent to the front panel 111 and the back panel 112, respectively. The first flange 115a is in contact with the front panel 111, and the second flange 115b is in contact with the back panel 112. The second side panel 116 is provided with a third flange 116a and a fourth flange 116b at both ends adjacent to the front panel 111 and the back panel 112, respectively. The third flange 116a is in contact with the front panel 111, and the fourth flange 116b is in contact with the back panel 112. This ensures that the first side panel 115 and the second side panel 116 are stably installed between the front panel 111 and the back panel 112.

[0078] Furthermore, the sound barrier unit panel 100 of the present application also includes: a first plate column rubber pad 174, a second plate column rubber pad 175, a third plate column rubber pad 176 and a fourth plate column rubber pad 177. The first plate column rubber pad 174 extends along the height direction and the first plate column rubber pad 174, the panel 111 and the first flange 115a are fixed by a fourth axial rivet. The second plate column rubber pad 175 extends along the height direction and the second plate column rubber pad 175, the back panel 112 and the second flange 115b are fixed by a fifth axial rivet. The third plate column rubber pad 176 extends along the height direction and the third plate column rubber pad 176, the panel 111 and the third flange 116a are fixed by a sixth axial rivet. The fourth plate column rubber pad 177 extends along the height direction and the fourth plate column rubber pad 177, the back panel 112 and the fourth flange 116b are fixed by a seventh axial rivet.

[0079] In some embodiments of the present application, the front panel 111, back panel 112, and connecting plate 113 are aluminum alloy plates. This ensures that the sound barrier unit panel 100 is lightweight while also maintaining sufficient strength. Preferably, the first column rubber pad 174, the second column rubber pad 175, the third column rubber pad 176, the fourth column rubber pad 177, the decoupling rubber pad 171, the first interlayer rubber pad 172, and the second interlayer rubber pad 173 are all made of EPDM rubber. The sound insulation material of the sound-absorbing and insulating assembly 130 can be rock wool board (or wood wool board, ceramsite board, etc.), and the protective material of the sound-absorbing and insulating assembly 130 can be aluminum alloy wire mesh or stainless steel wire mesh.
