Description

Technical Field

[0001] The utility model relates to the technical field of stamping metal structures, and particularly relates to a metal structural part and an electronic device. Background Art

[0002] In some products, to meet the assembly requirements, sometimes it is necessary to increase the height of a local area of a metal structural part to reduce the internal free space.

[0003] Figure 1 Fig. shows an assembly structure, which includes a stamping metal structural part 10, a double-sided adhesive 20 and a flat part 30. The flat part 30 is adhesively fixed on the stamping metal structural part 10 through the double-sided adhesive 20, and the flat part 30 serves to occupy the internal free space. To facilitate the positioning of the double-sided adhesive 20, a mark line 40 also needs to be added on the stamping metal structural part 10.

[0004] This assembly structure is composed of three components. Among them, a set of stamping dies is required for the stamping metal structural part, a set of punching dies is required for the double-sided adhesive, and a set of stamping dies is required for the flat part. The equipment cost is relatively high. Moreover, when the individual components are manufactured separately, fixtures, machines, and man-hours are also required during later assembly. Therefore, Figure 1 the shown assembly structure will result in a relatively high manufacturing cost. Summary of the Utility Model

[0005] The technical problem solved by the utility model is to provide a low-cost metal structural part with the function of occupying free space, and an electronic device with such a metal structural part.

[0006] To solve the above technical problem, the first technical solution adopted by the utility model is: a metal structural part, including a body and a space occupation part connected to the body. The space occupation part is folded from a partial area of the body. The space occupation part includes a connected bending arm and a support arm. The bending arm is connected to the edge of the body. When looking down at the metal structural part, the support arm is located within the projection area of the body.

[0007] In one embodiment, unloading grooves are respectively arranged on both sides of the connection between the bending arm and the body.

[0008] In one embodiment, the support arm is arranged parallel to the body.

[0009] In one embodiment, there is a gap between the support arm and the body.

[0010] In one embodiment, a support foot formed by bending is provided on the side of the support arm away from the bending arm, and the support foot contacts the body.

[0011] In one embodiment, a plurality of stamping holes are provided on the body.

[0012] In order to solve the above technical problems, the second technical solution adopted by the present utility model is: an electronic device, including the above-mentioned metal structural member.

[0013] The beneficial effects of the present utility model are as follows: The metal structural member is provided with a space occupation part for occupying the empty space inside the electronic device, and the space occupation part is formed by folding a partial area of the body. Without the need to assemble other components, the height of a partial area of the metal structural member is increased, the functions of the existing assembly structure are realized, the assembly requirements of the electronic device are met, the mold costs of double-sided tapes and flat parts and the component assembly costs are omitted, thereby greatly reducing the cost of the product. In addition, the body structure of the metal structural member does not need to be redesigned and manufactured with molds, and can be modified on the basis of the original molds, which is easy to promote and apply. Moreover, the production cost of the new structural bracket is basically the same as that of the old structural bracket. Description of the Drawings
