DETAILED DESCRIPTION

[0021] For the purpose of promoting an understanding of the application, the application will now be described in greater detail with reference to the figures. Embodiments of the application are illustrated in the drawings, wherein like reference numerals designate like elements in the various figures. The application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and fully convey the scope of the application to those skilled in the art.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0023] In conjunction with Figures 1-4 As shown in the drawings, an automobile A-pillar sound insulation pad comprises:

[0024] An A-pillar body 1 is a metal frame on an automobile and is arranged at both sides of a front windshield;

[0025] A side plate 2 is arranged on one side of the A-pillar body 1 and combined with the A-pillar body 1 to form a sealed mounting space;

[0026] A sound insulation pad 3 is arranged between the A-pillar body 1 and the side plate 2 to fill the gap therebetween, and the sound insulation pad 3 is a plastic foaming piece, and the main purpose is to realize the noise reduction function by using the closed cell foaming structure thereof;

[0027] A plurality of positioning assemblies 4 are arranged and fixedly installed at the edges of the sound insulation pad 3 to assist in the installation and fixation of the sound insulation pad 3.

[0028] Specifically, in the embodiment, the A-pillar body 1 and the side plate 2 are fixedly connected by a buckle structure and are reinforced by bolts, and a gap is left between the combination of the two, and the sound insulation pad 3 is installed in the gap to assist in noise reduction.

[0029] A plurality of through holes 31 are arranged at the edges of the surface of the sound insulation pad 3, and positioning grooves are formed at the edges of the top surface of the through holes 31, and a mounting groove 21 is also arranged on the surface of the side plate 2, which is a circular hole and is arranged concentrically with the through hole 31.

[0030] The positioning assembly 4 comprises a positioning column 41 fixedly installed in the through hole 31, which is in a cylindrical structure, and a rectangular clamping groove 42 is formed in the side wall of the lower half, which is arranged in a circumferential array along the side wall of the positioning column 41, and a clamping plate 43 is arranged in each clamping groove 42 to assist in fixation.

[0031] In addition, the top of the positioning column 41 is arranged flush with the top surface of the sound insulation pad 3, and the side wall thereof extends to the four sides to form a flange that is fitted in the positioning groove and is locked and fixed by glue or bolts.

[0032] A shallow groove is further arranged at the center of the top surface of the positioning column 41, and a blind hole 44 is arranged at the center of the groove bottom surface of the shallow groove. The blind hole 44 vertically extends downward to the inside of the lower half of the positioning column 41, and the clamping groove 42 extends inward and communicates with the blind hole 44.

[0033] A fixing shaft 45 is further vertically arranged in the blind hole 44. The bottom end of the fixing shaft 45 is arranged in a conical shape, and a thread structure that is matched with the blind hole 44 is further arranged between the fixing shaft 45 and the blind hole 44. Therefore, the fixing shaft 45 is screwed into the inside of the blind hole 44, and the conical surface at the bottom of the fixing shaft 45 is located near the clamping groove 42.

[0034] The outward surface of the clamping plate 43 is arranged in a flat surface, and the inward surface thereof is arranged in an inclined surface that is matched with the conical surface at the bottom of the fixing seat. Therefore, when the fixing shaft 45 is screwed downward, the clamping plate 43 is pushed outward by extrusion.

[0035] On this basis, the inner side wall of the mounting groove 21 further extends outward to form a plug groove 22. When the fixing shaft 45 is screwed downward, the clamping plate 43 that is pushed out is plugged into the inside of the plug groove 22 to achieve the locking function.

[0036] In addition to locking, in the actual use process, the subsequent recycling and disassembly problems also need to be considered. Therefore, an adjusting cap that is matched with the size of the shallow groove is further arranged at the top of the fixing shaft 45. An inner hexagonal hole is further arranged at the center of the top surface of the adjusting cap to facilitate the rotation of the staff by using an inner hexagonal wrench. A stepped surface is further arranged on the side wall of the clamping groove 42, and an elastic element 46 is further arranged on the stepped surface. The elastic element 46 can be a spring. In the natural state, the spring can pull the clamping plate 43 into the inside of the clamping groove 42, and the end surface thereof is arranged flush with the side wall of the fixing seat. Alternatively, the spring is retracted into the inside. In the subsequent disassembly process, only the fixing shaft 45 needs to be loosened, and the positioning assembly 4 and the side wall can be separated. Finally, the whole sound insulation board is disassembled.

[0037] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and not to limit them. Although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or equivalently replace some or all of the technical features. The modification or replacement does not change the essence of the corresponding technical solution from the technical solutions of the embodiments of the present application.
