Detailed Description

As shown in fig. 1, an electronic device, such as a display device, according to an embodiment of the present invention includes a panel 1, a display screen, a frame 2, a bracket 3, a PCB 4, an energy absorbing structure 5, and a rear cover 6.

The housing of the display device comprises a frame 2 and a rear cover 6.

In this embodiment, the rear cover 6 is a metal case.

In other embodiments, the rear cover 6 may also be an injection molded piece.

As shown in fig. 2, the rear cover 6 is provided with two pairs of elastic fixing pieces having a movable end:

elastic fixing pieces

61 and 62 and

elastic fixing pieces

63 and 64, wherein the movable ends of each pair of elastic fixing pieces (61, 62; 63 and 64) are oppositely arranged, the

elastic fixing pieces

61 and 62 are used for fixing the connector 71, and the

elastic fixing pieces

63 and 64 are used for fixing the connector 72.

The connector 71 is a power supply interface of the display device, and the connector 72 is an LVDS interface of the display device.

The elastic fixing piece 61 will be described as an example.

As shown in fig. 3, the movable end of the elastic fixing piece 61 is provided with a fixing portion 611 for fixing the device mounted on the PCB board 4 of the electronic apparatus, in this embodiment, the fixing portion 611 is used for fixing the connector 71, and 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 has elasticity.

The set value is determined by the material and thickness of the shell (the frame 2 and the rear cover 6), and the harder the material is, the smaller the set value is; and the softer the material, the larger the set value.

In this embodiment, the set value may be +2mm in diameter of the mounting hole 6111.

The fixing portion 611 is provided with a mounting hole 6111 to which the device is fixed. The fixing portion 611 needs to be selected according to the diameter of the mounting hole 6111, and the side length of the fixing portion 611 may be +6mm of the diameter of the mounting hole 6111, i.e. 3mm on each of the two sides of the mounting hole 6111.

In other embodiments, the fixing portion 611 may be provided with a plurality of mounting holes.

The elastic fixing piece 61 enables the mounting hole 6111 to be correspondingly adjusted in position in the direction perpendicular to the rear cover 6, and meanwhile, the mounting hole 6111 can also be adjusted in position in the direction close to the fixed end 612, so that the elastic fixing piece 61 can enable the mounting hole 6111 to be effectively adjusted in tolerance in multiple directions.

In this embodiment, the mounting hole 6111 is a circular hole.

In still another embodiment, as shown in fig. 4 and 5, a portion including a bend toward the inside of the rear cover 6 is provided between the fixed end 612 of the elastic fixing piece 61 and the fixed portion 611, and the fixed portion 611 is located on the inside of the rear cover 6, as shown in fig. 6.
