[0021] Please see Figures 1-5This utility model provides an embodiment of a sound-absorbing automotive interior headliner, including a headliner 1; it also includes a headliner panel 2 and a mounting assembly; the headliner panel 2 is provided at the lower end of the headliner 1, and the mounting assembly is provided inside the headliner panel 2. A through hole 3 is provided through the lower end of the headliner panel 2, and a connecting rod 101 is rotatably provided on the inner wall of the through hole 3. A limiting rod 102 is fixedly connected to the outer wall of the connecting rod 101. A mounting seat 103 is provided at the lower corner of the headliner 1. A first groove 104 is provided at the lower end of the mounting seat 103. A first limiting groove 105 is provided on the inner wall of the first groove 104. A spring 106 is fixedly connected to the top of the inner wall of the first groove 104. A second groove 107 is provided at the upper end of the connecting rod 101. Adapted to spring 106, the first limiting groove 105 is inverted L-shaped, and a second limiting groove 112 is provided at the end of the first limiting groove 105. The first limiting groove 105 and the second limiting groove 112 are adapted to the limiting rod 102. The connecting rod 101 is inserted into the first groove 104. By pressing the spring 106, the limiting post moves along the inner wall of the first limiting groove 105 to the top. Then, the connecting rod 101 is rotated to move the limiting post into the second limiting groove 112. Under the downward pressure of the spring 106, the connecting rod 101 can be fixed in the mounting base 103. This solves the problem that during disassembly and maintenance, there will be adhesive residue, which will cause the new adhesive layer to not adhere firmly and affect the connection effect of the ceiling.

[0022] Please see Figure 1 and Figure 3 In this embodiment, the mounting assembly includes a mounting plate 108, fixing bolts 109, a knob 110, and a fixing ring 111. The mounting plate 108 is provided at the lower corner of the top plate 1, and the mounting plate 108 is threaded with fixing bolts 109 at the lower end. There are four fixing bolts 109 distributed at the four corners. The fixing bolts 109 can evenly distribute the applied pressure, increase the stability of the structure, and prevent the mounting base 103 from loosening or shifting during use. The other end of the connecting rod 101 is fixed with a knob 110, and the outer wall of the connecting rod 101 is threaded with a fixing ring 111. The upper end face of the fixing ring 111 is in contact with the lower end face of the ceiling plate 2.

A sound-absorbing layer 7 is provided at the lower end of the reflective layer 6. The sound-absorbing layer 7 is composed of a sound-absorbing board and sound-absorbing cotton. Through the combination of the reflective layer 6 and the sound-absorbing layer 7, the propagation of sound can be effectively reduced. The reflective layer 6 reflects a part of the sound back to the sound-absorbing layer 7, and the sound-absorbing layer 7 absorbs this sound, thereby minimizing noise.

[0024] In use, the sound-absorbing block 5 is first placed between the two partition plates 4. Then, the connecting rod 101 is inserted into the first groove 104. By pressing the spring 106, the limiting post is moved to the top along the inner wall of the first limiting groove 105. Then, the connecting rod 101 is rotated to move the limiting post into the second limiting groove 112. Under the downward pressure of the spring 106, the connecting rod 101 can be fixed in the mounting base 103. This solves the problem that when disassembling and maintaining, there will be adhesive residue, which will cause the new adhesive layer to not adhere firmly and affect the connection effect of the ceiling. Then, by rotating the fixing ring 111, the ceiling panel 2 can be in close contact with the ceiling panel 1, improving the sound absorption effect.
