Problems solved by technology

[0004] However, complex structures such as locking elements or clamping structures on the metal shell are difficult to complete simultaneously through the above-mentioned stamping process
At present, the industry generally adopts laser welding to weld shrapnel, studs, etc. and the metal shell together. However, this laser welding method is likely to cause deformation or discoloration of the metal shell due to the influence of laser energy, resulting in poor product appearance.

Embodiment Construction

[0014] Please also see figure 1 and figure 2 , The electronic product according to the preferred embodiment 1 of the present invention includes a metal connecting structure 20 , which includes a metal shell 21 , a hot melt adhesive layer 23 and an elastic piece 25 . The elastic piece 25 is fixed inside the metal shell 21 through the hot melt adhesive layer 23 .

[0015] In this embodiment, the metal connection structure 20 is applied to mp3 electronic products. The metal shell 21 is a curved shell. The elastic piece 25 is formed by stamping, and includes a rectangular base 251 and a U-shaped elastic portion 252 . Two legs of the U-shaped elastic portion 252 extend outward from one end of the base portion 251 . The shape of the hot-melt adhesive layer 23 matches the shape of the base portion 251 of the elastic piece 25 , so that the hot-melt adhesive layer 23 is in full contact with the base portion 251 . The hot melt adhesive layer 23 is a solvent-free adhesive, which ha...

Description

technical field [0001] The invention relates to an electronic product with a metal connection structure and a preparation method thereof. Background technique [0002] At present, in order to pursue high mechanical strength and aesthetic effect, some electronic products such as personal digital assistants, notebook computers, digital cameras, mobile phones, mp3 and mp4 use metal casings, such as stainless steel or magnesium-aluminum alloy casings. [0003] The metal shells in the above-mentioned electronic products are generally processed by sheet metal stamping. Various locking elements or clamping structures need to be provided on the inner surface of the metal casing to limit various components inside the electronic product, or to lock the metal casings to each other. More generally, the inner surface of the metal shell needs to be fixedly connected with various shrapnel structures for supporting the components inside the electronic product; and the inner surface of the ...
