Its effect is described in detail below.

The aforementioned and other technical contents, features and effects of the present utility model will be clearly presented in the following detailed description of preferred embodiments with reference to the drawings. Through the description of the specific implementation, one can get a deeper and more specific understanding of the technical means and effects of the utility model to achieve the intended purpose, but the attached drawings are only for reference and description, and are not used to explain the present invention. Utility models are restricted.

Please refer to FIG. 1 and FIG. 2 . FIG. 1 is a three-dimensional schematic view of the appearance of the two-stage elastic sheet 30 of the present invention, and FIG. 2 is a side sectional view of the two-stage elastic sheet 30 . The two-stage shrapnel 30 of the preferred embodiment of the present utility model is formed by punching a metal sheet, and is fixed on the upper surface of a second object 34 to support a first object 32 and slow down the vibration of the first object 32. It is often used in automotive electronic devices or portable electronic devices. In this type of electronic device, the first object 32 is usually a circuit substrate.

The two-stage elastic sheet 30 of the preferred embodiment of the present invention includes a base plate 40 , a rear side plate 42 , a top support plate 44 , a front side plate 45 and a height stop plate 46 .

The base plate 40 is used to be fixed on the upper surface of the second object 34 at the bottom. The second object 34 is usually a fixed substrate at the bottom of the electronic device, so the first object 32 is supported by the two-stage elastic sheet 30, To be fixedly arranged above the second object 34 . In practice, a few copper pillars can be provided to support the first object 32 together with several two-stage shrapnels 30 .

The rear side panel 42 extends upwardly and inwardly (inwardly and upwardly) from the rear edge of the base plate 40 through a first corner 48 .

The top support plate 44 extends laterally from the upper edge of the rear side plate 42 toward the inner side (forward direction).

The front side plate 45 extends downward from the front edge of the top support plate 44 and extends inwardly (backward direction), wherein the front side plate 45 defines a connecting hole 4502 .

The height stop plate 46 extends obliquely from the base plate 40 adjacent to the first corner 48 upwards and lifts forward. The upper end of the height stop plate 46 passes through the connecting hole 4502 from the inside to the outside, and its end is A hook plate 4602 is further folded downward, and the hook plate 4602 is in a structure that interferes with the front side plate 45 .

Wherein, the height-stopping plate 46 straddles the middle section of the base plate 40 to separate the base plate 40 into a left base plate 4002 and a right base plate 4004 , thus creating a gap in the middle of the base plate 40 . The existing conventional technology uses solder paste to solidify and bond the base plate 40 on the second object 34 to fix the shrapnel. The peripheral edge of the base plate 4004 is formed by solidification welding, especially through the gap, so as to more stably fix the base plate 40 on the upper surface of the second object 34 .

In addition, as the aforementioned two-stage shrapnel 30, although it mainly uses the top support plate 44 to support the first object 32, the outer surface of the rear side plate 42 of the present utility model is also designed as a wide attachment surface, so it can cooperate with The shape of the bottom of the first object 32 is designed, and the outer surface of the rear side plate 42 is also in a structure for supporting the first object 32 .

Like the aforementioned two-stage elastic piece 30 , an elastic hole 4802 can be further excavated at the first corner 48 . The elasticity of the entire two-stage elastic piece 30 can be further adjusted by the size of the elastic hole 4802 in addition to being determined by the first angle 48 and the material of the elastic piece.

It should be added that there is a first distance between the hook plate 4602 and the upper edge of the connecting hole 4502, and a second distance between the lower edge of the front side plate 45 and the base plate 40, and the second distance is greater than the first distance. In this way, when the top support plate 44 is under pressure, the rear side plate 42 will be an elastic body to bear the load. When the subsequent deep depression continues, the upper edge of the connection hole 4502 will press against the upper surface of the hook plate 4602, and the height stop plate 46 will assist as the second load-bearing elastic body. At this time, the second distance needs to be greater than the first distance to form the above-mentioned two-stage pressure bearing mode.

When excessive deep pressure, after the height stop plate 46 becomes the second elastic body, the lower side edge of the front side plate 45 will contact the base plate 40, and then the front side plate 45 becomes the third elastic body, which can make the utility model The two-stage shrapnel 30 has a better effect.

Therefore, the two-stage shrapnel 30 of the present invention utilizes the combination of the height stop plate 46 and the front side plate 45 to withstand greater pressure in two stages, thereby improving the reliability of the electronic device in use. Further, the front side plate 45 is restrained by the hook plate 4602 on the upper end of the height stop plate 46, even if it is subjected to lateral (transverse) stress, it can also prevent the shrapnel from bursting or laterally deformed and difficult to recover.

The above are only preferred embodiments of the present utility model, and do not limit the utility model in any form. Although the utility model has been disclosed as above with preferred embodiments, it is not intended to limit the utility model. Any Those skilled in the art can use the technical content disclosed above to make some changes or modify them into equivalent embodiments without departing from the technical solution of the present utility model. Content, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the utility model still belong to the scope of the technical solution of the utility model.
