Description

Spring sheet with double-layer structure Technical Field The utility model relates to the technical field of spring plates, in particular to a spring plate with a double-layer structure. Background Along with the rapid development of technology, the standard of requirements of people on the use and appearance of mobile phones is higher, products such as mobile phones are more flexible, the miniaturization development of internal hardware of mobile phones is promoted, and the product welding strength in the SMT welding process can be met under the requirement that the elastic sheet product can meet miniaturization in the whole machine. In the prior art, the welding strength of the product is often insufficient, so that the welding area of the product is increased to meet the welding strength, the whole machine structure is further increased, and the problems of cost increase and space occupation are caused. Therefore, the problem existing in the prior art is solved by designing the elastic sheet, the welding strength can be increased, the elastic sheet can be prevented from deforming, the space structure of the whole machine can be effectively reduced, the cost is saved, and the service life of the elastic sheet is prolonged. Disclosure of utility model The utility model provides the spring plate with the double-layer structure, which not only can prevent deformation of the spring plate, but also can improve the welding strength of the spring plate, and can meet the performance requirement of a product by adopting the design of the double-layer structure and the welding pins while meeting the miniaturization requirement. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: providing a spring sheet with a double-layer structure, which comprises a first plate-shaped base part; The side walls are formed by bending and extending the two side edges of the first plate-shaped base part respectively and are oppositely arranged; An elastic portion extending from one end of the first plate-shaped base portion into an open space formed between the two side walls; The other end of the first plate-shaped base is bent outwards and extends out of the second plate-shaped base, one side edge of the second plate-shaped base is bent and extends out of the first protection wing upwards, one side edge of the first protection wing is bent and extends out of the connecting part, and the other side edge of the connecting part extends out of the second protection wing. Preferably, the first protecting wing and the second protecting wing are arranged oppositely.
