This utility model relates to the field of automotive fabric technology, specifically to a 3D-MESH fabric for car audio systems. It includes a bottom cover, a top cover, and a fabric material disposed between the two. The fabric material comprises a MESH layer and a metal mesh fabric, which are bonded together using PA mesh hot melt adhesive. The metal mesh fabric includes memory foam fabric, a metal mesh, and carbon fiber fabric. Both ends of the metal mesh are bonded to the memory foam fabric and the carbon fiber fabric. The metal mesh provides better protection, preventing damage to the internal components of the audio system from external objects. The memory foam fabric improves the fit and stability of the audio system installation, reducing vibration and friction noise caused by vehicle bumps. Finally, the carbon fiber fabric enhances the stability of the audio structure, reduces deformation caused by vibration, helps maintain accurate sound quality, and its good thermal conductivity helps dissipate heat, improving system reliability and lifespan.

The utility model discloses a top and bottom separation type packing box of square shell battery relates to battery packing box technical field, including bottom shell, top shell, the both sides of bottom shell and top shell are provided with recess, and recess coincides and forms side hand hole, the both sides of top shell top are provided with hand to hold the hole, and the both sides of top shell top are fixed with support buckle frame, the utility model discloses packing box is by bottom shell and top shell cooperation constitutes, wherein bottom shell and top shell buckle in the process, and positioning column corresponds to insert into corresponding positioning hole, can bear certain tension and shearing force, prevent bottom shell and top shell accidental separation in the transportation or use process, and the overall connection strength and stability of packing box are strengthened, after bottom shell and top shell buckle, and the handle is moved to the down, makes the hook corresponding buckle on the lock catch, realizes further buckle locking, thereby enhances the firmness of bottom shell and top shell connection, makes square shell battery storage more safe and reliable.
