[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0016] like Figures 1 to 3 As shown, a new structure of a combination of an A-pillar upper structural reinforcement and a cavity sound insulation block includes a frame 1, an EVA sound insulation block 2 and a buckle 3.

[0017] A plurality of grooves are provided on the side of the skeleton 1 , and epoxy glue 101 is provided in the grooves. A positioning groove is provided on the surface of the skeleton 1 , and the EVA sound insulation block 2 is installed in the positioning groove.

[0018] The EVA sound insulation block 2 has an opening at one end and multiple cavities inside. The skeleton 1 and the buckle 3 are installed in the same cavity near the opening, and positioning grooves for positioning the skeleton 1 and the buckle 3 are respectively provided on both sides of the cavity.

[0019] A self-locking structure is provided at the opening of the EVA sound insulation block 2, and the self-locking structure includes a positioning plate 201 and a limiting plate 202 respectively connected to the two sides of the opening of the EVA sound insulation block 2. The EVA sound insulation block 2, the positioning plate 201 and the limiting plate 202 are integrally formed, and the limiting plate 202 is located on the outside of the positioning plate 201. The positioning plate 201 is an L-shaped structure and is clamped to the outside of the frame 1. A through groove adapted to the buckle 3 is provided on the limiting plate 202.

[0020] In specific use, by combining the skeleton 1 and the EVA sound insulation block 2, only one clip 3 is needed to clip the EVA sound insulation block 2. The process is simple, the cost is low, and the clipping position can be arbitrarily arranged in any positioning groove on the skeleton 1.
