[0009] Further, the mounting hole is a round hole.
[0010] Further, the housing is made of a metal plate, and the elastic fixing piece is formed by punching.
[0011] Further, the housing is a plastic injection part, and the elastic fixing piece is formed in one piece with the housing.
[0012] Further, the set value is determined based on the material and the thickness of the housing.
[0013] Further, there are two elastic fixing pieces, and the fixing portions of the elastic fixing pieces are arranged opposite to each other. [0014] The present invention also provides an electronic device, comprising the housing for an electronic device described above and a PCB, wherein a first component is provided on the PCB, and the first component is fixed by the elastic fixing piece at a corresponding position of the housing for an electronic device.
[0015] Compared with the prior art, the housing for an electronic device and the electronic device provided by the present invention have the following benefits: the housing is provided with an elastic fixing piece with a movable end, so that the position of the mounting hole can not only be adjusted in a direction perpendicular to the mounting hole, but can also be adjusted in a plurality of directions in the plane of the mounting hole, to ensure effective tolerance in a plurality of directions.

[0023] The housing of the display device comprises the frame 2 and the rear cover 6.
[0024] In this embodiment, the rear cover 6 is a metal housing.
[0025] In other embodiments, the rear cover 6 may also be a plastic injection part.
[0026] As shown in Figure 2, the rear cover 6 is provided with two pairs of elastic fixing pieces with a movable end: the elastic fixing pieces 61 and 62 and the elastic fixing pieces 63 and 64, wherein the movable ends of each pair of the elastic fixing pieces (61 and 62; 63 and 64) are arranged opposite to each other. The elastic fixing pieces 61 and 62 are used for fixing a connector 71, and the elastic fixing pieces 63 and 64 are used for fixing a connector 72.
[0027] The connector 71 is the power supply connector of the display device, and the connector 72 is the LVDS connector of the display device.
[0028] The elastic fixing piece 61 is taken as an example in the description below. [0029] As shown in Figure 3, the movable end of the elastic fixing piece 61 is provided with a fixing portion 611, used for fixing a component mounted on the PCB 4 of the electronic device. In this embodiment, the fixing portion 611 is used for fixing the connector 71. The width of the fixed end 612 of the elastic fixing piece 61 is smaller than a set value, so that the elastic fixing piece 61 is elastic.
[0030] The set value is determined based on the material and the thickness of the housing (the frame 2 and the rear cover 6). The harder the material, the smaller the set value; the softer the material, the greater the set value.
[0031] In this embodiment, the set value may be the diameter of the mounting hole 6111 + 2 mm.
[0032] The fixing portion 611 is provided with a mounting hole 6111 for fixing a component. The fixing portion 611 needs to be selected based on the diameter of the mounting hole 6111, and the side length of the fixing portion 611 may be the diameter of the mounting hole 6111 + 6 mm, i.e., 3 mm on each side of the mounting hole 6111.
[0033] In other embodiments, a plurality of mounting holes may be provided on the fixing portion 611.
[0034] The elastic fixing piece 61 makes it possible to adjust the position of the mounting hole 6111 in a direction perpendicular to the rear cover 6, and at the same time, the position of the mounting hole 6111 can also be adjusted closer to the fixed end 612, so that the elastic fixing piece 61 enables the mounting hole 6111 to provide tolerance effectively in a plurality of directions. [0035] In this embodiment, the mounting hole 6111 is a round hole.
[0036] In another embodiment, as shown in Figure 4 and Figure 5, a portion bent toward the inside of the rear cover 6 is provided between the fixed end 612 and the fixing portion 611 of the elastic fixing piece 61, and the fixing portion 611 is positioned at the inner side of the rear cover 6, as shown in Figure 6. In other embodiments, a portion curved toward the inside of the rear cover 6 (for example, in an S shape) may also be provided between the fixed end 612 and the fixing portion 611 of the elastic fixing piece 61.
[0037] In yet another embodiment, a portion bent toward the outside of the rear cover is provided between the fixed end and the fixing portion of the elastic fixing piece. In other embodiments, a portion curved toward the outside of the rear cover is provided between the fixed end and the fixing portion of the elastic fixing piece.
[0038] The elastic fixing piece 61 makes it possible to adjust the position of the mounting hole 6111 in a direction perpendicular to the mounting hole 6111 and at the same time away from the fixed end 612, so that the elastic fixing piece 61 enables the mounting hole 6111 to provide tolerance effectively in a plurality of directions.
[0039] The width of the curved or bent portion increases gradually from the width of the fixed end 612 to the width of the fixing portion 611, to improve the flexibility of the elastic fixing piece 61.
[0040] In this embodiment, the rear cover 6 is made of a metal plate, and the elastic fixing piece 61 is formed by punching. In other embodiments, the housing may also be a plastic injection part, and the elastic fixing piece is formed in one piece with the housing.
[0041] In yet another embodiment, it is not necessary that two elastic fixing pieces opposite to each other are provided. For example, one elastic fixing piece may fix one component, or three elastic fixing pieces distributed evenly along the circumference may be used to fix one component.
[0042] The present invention provides a housing for an electronic device, which is provided with an elastic fixing piece with a movable end, wherein the movable end is provided with a fixing portion used for fixing a component mounted on a PCB of an electronic device, and the width of the fixed end of the elastic fixing piece is smaller than a set value. The present invention also provides an electronic device. In the housing for an electronic device and the electronic device provided by the present invention, the housing is provided with an elastic fixing piece with a movable end, so that the position of the mounting hole can not only be adjusted as required in a direction perpendicular to the mounting hole, but can also be adjusted as required in a plurality of directions in the plane of the mounting hole, to ensure tolerance is effectively provided in a plurality of directions.
[0043] Although the present invention has been disclosed above through preferred embodiments, it is by no means limited to these. Various changes and modifications made by any of those skilled in the art without departing from the spirit and scope of the present invention shall be included in the scope of the present invention, and therefore the scope of the present invention shall be that defined by the claims.
