The first folding plate 111 is located on one side of the fixing assembly 110, and the second folding plate 112 is located on the other side of the fixing assembly 110. The first folding plate 111 is, for example, an orifice plate, which has an opening 111a through which a fixing member (such as a screw, not shown in the figure) can pass through the opening 111a and be locked on the first fixing seat 121 of the housing assembly 120 And the first folded plate 111 is made to abut against the abutting surface 121a and adhere to it. The second folding plate 112 includes, for example, a first orifice plate 113 and a second orifice plate 114 opposite to each other. The first orifice plate 113 and the second orifice plate 114 are non-parallel opposite, but the first orifice plate 113 and the second orifice plate 114 are opposite to each other. 114 is relatively inclined at an angle.

In one embodiment, the second orifice plate 114 is substantially parallel to the circuit board 100, and the first orifice plate 113 has a second adaptation angle θ 2 with respect to the circuit board 100, and the second adaptation angle θ 2 is the same as that of the first folding plate 111. The first adaptation angle θ 1 relative to the circuit board 100 is substantially the same, but can also be different.

In this embodiment, there is a gap between the first orifice plate 113 and the second orifice plate 114 for clamping the circuit board 100 between the first orifice plate 113 and the second orifice plate 114. The first orifice plate 113 has a first opening 113a, and the second orifice plate 114 has a second opening 114a. The size of the second opening 114a can be larger than the size of the first opening 113a, so that the second fixing seat 122 can pass through the second opening 114a. The two orifice plates 114 abut under the first orifice plate 113, and another fixing member (such as a screw, not shown in the figure) can pass through the first opening 113a and the opening 101 of the circuit board 100 to be locked to the housing On the second fixing seat 122 of the component 120, the first orifice plate 113 abuts against the abutting surface 122 a and is attached to the abutting surface 122 a so that the circuit board 100 can be parallel to the inclined surface 125.

Please refer to FIGS. 1A and 1B. The circuit board 100 is provided with a module 102, such as a USB power supply module or other interface modules, for example, which is not limited by the present invention. An insertion end 103 of the module 102 can protrude from the surface of the circuit board 100 and is correspondingly exposed in a slot 123 of the housing assembly 120, as shown in FIG. 4. In other words, from the appearance point of view, the module 102 is accommodated in the housing assembly 120, and only the insertion end 103 is exposed in the slot 123. The module 102 is a USB slot, and the slot 123 is outside the housing assembly 120. USB opening.

Referring to FIGS. 1A and 1B, the fixing assembly 110 further includes two positioning members 115 extending to both sides of the module 102. The two positioning members 115 can position the module 102 to increase the assembly quality of the circuit board 100.

Please refer to FIGS. 2A and 2B, the housing assembly 120 has, for example, an inclined surface 125. The first fixing seat 121 and the second fixing seat 122 are disposed on the inclined surface 125 to form a height difference. In an embodiment, the height H1 of the first fixing base 121 is lower than the height H2 of the second fixing base 122, or the height H1 of the first fixing base 121 is equal to the height H2 of the second fixing base 122, for example. When the fixing assembly 110 is assembled on the first fixing seat 121 and the second When the two fixing bases 122 are attached, the first folding plate 111 matches the first fixing base 121 and is fixed on the abutting surface 121a of the first fixing base 121, and the second folding plate 112 matches the second fixing base 122 to be fixed to the second fixing base. On the abutting surface 122a of the fixing base 122.

It is worth noting that the first fitting angle θ 1 between the first folding plate 111 and the first fixing seat 121 and the second fitting angle θ 2 between the second folding plate 112 and the second fixing seat 122 are related to the inclination The inclination angle θ of the surface 125 is related. For example, when the inclination angle θ of the inclined surface 125 is 25 degrees, the first fitting angle θ 1 between the first folding plate 111 and the first fixing seat 121 can be obtained by bending the first The angle of a folded plate 111 is adjusted to a predetermined angle (for example, 25 degrees), and the second adaptation angle θ 2 between the second folded plate 112 and the second fixing base 122 can be achieved by bending the second folded plate 112 When the angle of inclination θ of the inclined surface 125 is 30 degrees, the first fitting angle θ 1 between the first folding plate 111 and the first fixing seat 121 can be adjusted to a predetermined angle (for example, 25 degrees). By bending the angle of the first folding plate 111 to adjust it to a predetermined angle (for example, 30 degrees), the second fitting angle θ 2 between the second folding plate 112 and the second fixing base 122 can be adjusted by bending The angle of the second folding plate 112 is adjusted to a predetermined angle (for example, 30 degrees). Therefore, when the inclination angle θ of the inclined surface 125 changes, the height difference between the first fixing seat 121 and the second fixing seat 122 will also be changed. It changes accordingly, and therefore, the first folding plate 111 and the second folding plate 112 must be bent appropriately so that the first fitting angle θ 1 and the second fitting angle θ 2 can be adjusted with the height difference.

In one embodiment, the first adaptation angle θ 1 is substantially equal to the second adaptation angle θ 2, but the first adaptation angle θ 1 can also be greater or smaller than the second adaptation angle θ 2, which can be adjusted according to actual conditions The present invention does not impose restrictions on this.

In this embodiment, the circuit board 100 is assembled on the inclined surface 125 of the housing assembly 120, and the circuit board 100 is substantially parallel to the inclined surface 125, so that the module 102 on the circuit board 100 can be arranged perpendicular to the inclined surface 125 .

In addition, two grooves 104 are provided on opposite sides of the circuit board 100 for accommodating the first limiting member 124 and the second limiting member 124. In addition, the surface of the circuit board 100 rests on the platform below the first limiting member 124 and the second limiting member 124, so that the circuit board 100 and the housing assembly 120 can be separated by a predetermined distance, for example, about the size of the module 102 The height is such that the insertion end 103 of the module 102 is substantially aligned with the slot 123 of the housing assembly 120, as shown in FIG. 4.

The circuit board fixing structure described in the above embodiment of the present invention can be used in a display, wherein the circuit board can be fixed on the inclined surface of the housing assembly of the display.
