[0029] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” “the,” and “the” used herein may also include the plural forms. It should be further understood that the term “comprising” as used in the specification of this application means the presence of the stated features, elements, and / or components, but does not exclude the presence or addition of one or more other features, elements, components, and / or groups thereof. The term “and / or” as used herein includes all or any units and all combinations thereof of one or more associated listed items.

[0030] like Figure 1-5 As shown, this application embodiment provides a sound guide structure, which mainly includes a door panel 1 and a map pocket structure 2. The door panel 1 has an insertion hole 11, and a first arc-shaped plate 12 protruding to one side is formed along the edge of the insertion hole 11; the map pocket structure 2 is detachably connected to the door panel 1; the map pocket structure 2 forms a second arc-shaped plate 21 protruding to one side; the second arc-shaped plate 21 passes through the insertion hole 11, and the first arc-shaped plate 12 and the second arc-shaped plate 21 are combined to form a sound guide.

[0031] In this embodiment, the insertion hole 11 is formed along the thickness direction of the door panel 1. The first arc-shaped plate 12 is part of the edge of the insertion hole 11. The length of the second arc-shaped plate 21 is greater than that of the first arc-shaped plate 12. The side length of the second arc-shaped plate 21 is greater than that of the insertion hole 11, and the first arc-shaped plate 12 and the second arc-shaped plate 21 are joined together to form a cylindrical sound guide tube.

[0032] The sound guide structure provided in this embodiment divides the sound guide into two arc-shaped structures: a first arc-shaped plate 12 and a second arc-shaped plate 21. The first arc-shaped plate 12 is formed on the door trim panel 1, and the second arc-shaped plate 21 is formed on the door trim pocket structure 2. The pocket structure 2 is detachably connected to the door trim panel 1, facilitating assembly and disassembly. When the sound guide is damaged, only the corresponding door trim panel 1 or pocket structure 2 needs to be replaced, without replacing the entire door panel, thus saving repair costs.

[0033] like Figure 2-5 As shown, in one optional implementation, a first positioning structure 13 is formed on the inner side of the first arc plate 12 of the door panel 1; a second positioning structure 22 is formed on the outer side of the second arc plate 21 of the map pocket structure 2 for cooperating with the first positioning structure 13; one of the first positioning structure 13 and the second positioning structure 22 is a positioning hole 11, and the other is a positioning protrusion.

[0034] Based on the aforementioned embodiments, in this embodiment, the first positioning structure 13 is a positioning insertion hole 11, and the second positioning structure 22 is a positioning protrusion. A horizontal plate is formed on the inner side of the first arc-shaped plate 12, and the first positioning structure 13, i.e., the positioning insertion hole 11, is formed along the thickness direction of the horizontal plate. The second arc-shaped plate 21 has an open opening, and the second positioning structure 22 is formed at the opening to correspond to the first positioning structure 13. The second positioning structure 22 protrudes from the map pocket structure 2 and is in the same protruding direction as the second arc-shaped plate 21.

[0035] like Figure 2-5 As shown, in one optional implementation, a first snap-fit ​​structure 14 is formed at the edge of the socket 11, which is disposed away from the first positioning structure 13; a second snap-fit ​​structure 23 is formed on the outer side of the second arc-shaped plate 21 of the map pocket structure 2 for cooperating with the first snap-fit ​​structure 14, which is disposed away from the second positioning structure 22; both the first snap-fit ​​structure 14 and the second snap-fit ​​structure 23 are hooks.

[0036] Based on the aforementioned embodiments, in this embodiment, the first arc-shaped plate 12 and the second arc-shaped plate 21 are assembled to form a sound guide tube. The edge of the insertion hole 11 surrounds the outside of the second arc-shaped plate 21, and most of the edge of the insertion hole 11 forms a gap with the second arc-shaped plate 21. The second arc-shaped plate 21 and the edge of the insertion hole 11 enclose a gap area, which is a reserved demolding space. The second snap-fit ​​structure 23 is formed in the gap area. This can reduce the amount of material used and reserve sufficient demolding space, thereby reducing the cost of parts and mold development expenses. The first snap-fit ​​structure 14 is formed on the outside of the edge of the insertion hole 11 and extends to the inside of the edge of the insertion hole 11 to snap with the second snap-fit ​​structure 23.

[0037] like Figure 5 As shown, in one optional implementation, the connecting end of one of the first arc-shaped plate 12 and the second arc-shaped plate 21 forms a limiting groove 3, and the connecting end of the other extends into the limiting groove 3.

[0038] Based on the aforementioned embodiments, in this embodiment, the two connecting ends of the first arc-shaped plate 12 have limiting grooves 3, which are recessed from the inside out along the thickness direction of the first arc-shaped plate 12. The two connecting ends of the second arc-shaped plate 21 are located inside the limiting grooves 3, that is, inside the two connecting ends of the first arc-shaped plate 12, thus restricting the two connecting ends of the second arc-shaped plate 21 within the limiting grooves 3, preventing the first arc-shaped plate 12 and the second arc-shaped plate 21 from misaligning and loosening, and ensuring the stability of the sound guide tube.

[0039] like Figure 1 and 5 As shown, as an optional implementation, the map pocket structure 2 has a group of sound holes 4, and the second arc-shaped plate 21 is arranged around the outside of the group of sound holes 4.

[0040] The above solution can guarantee sound transmission quality.

[0041] like Figure 2-5 As shown, in one optional implementation, a third positioning structure 15 is formed on the outside of the insertion hole 11; a fourth positioning structure 24 is formed on the outside of the second arc-shaped plate 21 of the map pocket structure 2 for cooperating with the third positioning structure 15; one of the third positioning structure 15 and the fourth positioning structure 24 is a positioning insertion hole 11, and the other is a positioning protrusion.

[0042] Based on the foregoing embodiments, in this embodiment, the third positioning structure 15 is a positioning insertion hole 11, which is a rectangular hole. The fourth positioning structure 24 is plate-shaped, and the protrusion direction of the fourth positioning structure 24 is the same as the protrusion direction of the second arc-shaped plate 21.

[0043] like Figure 2-5As shown, in one optional implementation, a fifth positioning structure 16 is formed on the outside of the insertion hole 11 of the door panel 1; a sixth positioning structure 25 is formed on the outside of the second arc plate 21 of the map pocket structure 2 for cooperating with the fifth positioning structure 16; one of the fifth positioning structure 16 and the sixth positioning structure 25 is a positioning insertion hole 11, and the other is a positioning protrusion.

[0044] Based on the foregoing embodiments, in this embodiment, the fifth positioning structure 16 is a positioning insertion hole 11, which is a circular hole. The sixth positioning structure 25 is columnar, and the protruding direction of the sixth positioning structure 25 is the same as the protruding direction of the second arc-shaped plate 21.

[0045] As an optional implementation, the door trim panel 1 is integrally formed with the first arc-shaped panel 12.

[0046] By adopting the above solution, the connection strength between the door trim panel 1 and the first arc-shaped panel 12 can be improved.

[0047] As an optional implementation, the map pocket structure 2 is integrally formed with the second arc-shaped plate 21.

[0048] By adopting the above scheme, the connection strength between the map bag structure 2 and the second arc plate 21 can be improved.
