According to an embodiment of the present invention, a fixing structure of a circuit board is provided for a display, wherein the circuit board can be fixed on an inclined surface of a display housing (i.e., a housing component) by a metal sheet (i.e., a fixing component). Because different display shells can not form the fixed seats with the same height difference on the inclined planes of the different display shells, metal sheet metal parts suitable for the circuit board are manufactured aiming at the different shells, and the initial angle between the metal sheet metal parts and the fixed seats is adjusted through the bendable folded plate, so that the circuit board is stably fixed on the inclined planes of the display shells, the metal sheet metal parts do not need to be manufactured again, and the manufacturing cost is reduced.

Fig. 4 is a schematic view of a fixing structure of the circuit board 100 according to another view angle of the present invention.

The fixing structure of the circuit board 100 includes a housing assembly 120 and a fixing assembly 110. The housing assembly 120 includes a first fixing seat 121 and a second fixing seat 122, the first fixing seat 121 has a height difference with respect to the second fixing seat 122, and both the first fixing seat 121 and the second fixing seat 122 can be configured as a cylinder; the top end of the first fixing seat 121 is provided with an abutting surface 121a (i.e., a first abutting surface 121a), and the top end of the second fixing seat 122 is provided with an abutting surface 122a (i.e., a second abutting surface 122a), so that in practical application, when the vertical surface connected with the inclined surface on the display is placed on the horizontal bearing surface, the abutting surface 121a and the abutting surface 122a are both parallel to the horizontal bearing surface, which allows an assembler to conveniently install the fixing component 110 in the vertical direction. Specifically, the display housing includes a front surface, a side surface, and a back surface, the back surface is parallel or substantially parallel to the front surface, the side surface connects the front surface and the back surface, the side surface includes four inclined surfaces, an included angle between each inclined surface and the front surface is an acute angle, an included angle between each inclined surface and the back surface is an obtuse angle, the above-mentioned vertical surface is a part of the back surface, the vertical surface, the contact surface 121a, and the contact surface 122a are parallel to each other, when the display housing is vertically and horizontally placed on a horizontal bearing surface, the vertical surface is perpendicular to the horizontal bearing surface, and the contact surface 121a and the contact surface 122a are perpendicular to the horizontal bearing surface.

The fixing assembly 110 is assembled on the circuit board 100, and is used for fixing the circuit board 100 on the first fixing seat 121 and the second fixing seat 122 of the housing assembly 120, the fixing assembly 110 includes a first folding plate 111 and a second folding plate 112, when the fixing assembly 110 and the housing assembly 120 are assembled, the first folding plate 111 is matched with the first fixing seat 121, the first folding plate 111 has a first adaptive angle θ 1 relative to the circuit board 100, the second folding plate 112 is matched with the second fixing seat 122, and the second folding plate 112 has a second adaptive angle θ 2 relative to the circuit board 100, wherein the first adaptive angle θ 1 and the second adaptive angle θ 2 are adjusted along with the height difference.

As shown in fig. 1A and 1B, the fixing element 110 is, for example, a metal sheet, and the material thereof may be aluminum alloy or stainless steel. The first flap 111 is located on one side of the fixed assembly 110 and the second flap 112 is located on the other side of the fixed assembly 110. The first folding plate 111 is, for example, a hole plate, which has an opening 111a, and a fixing element (e.g., a screw, not shown) can pass through the opening 111a and be locked on the first fixing seat 121 of the housing assembly 120, so that the first folding plate 111 abuts against the abutting surface 121a and even abuts against the abutting surface 121 a. The second flap 112 includes, for example, a first aperture plate 113 and a second aperture plate 114 that are opposed, the first aperture plate 113 and the second aperture plate 114 are opposed in a non-parallel manner, and the first aperture plate 113 and the second aperture plate 114 are inclined at a second initial angle relative to each other.

In one embodiment, when the fixing assembly 110 is assembled with the circuit board 100, the second aperture plate 114 is parallel or substantially parallel to the circuit board 100, so that the first aperture plate 113 has the second initial angle relative to the circuit board 100, and at this time, the first flap 111 has the first initial angle relative to the circuit board 100. The first initial angle and the second initial angle are equal or substantially equal such that the first flap 111 is parallel to the first aperture panel 113. In practice, the first initial angle and the second initial angle may not be equal.

In the present embodiment, a gap is formed between the first aperture plate 113 and the second aperture plate 114 for clamping the circuit board 100 between the first aperture plate 113 and the second aperture plate 114. The first aperture plate 113 has a first opening 113a, the second aperture 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 aperture plate 114 and abut against the lower side of the first aperture plate 113, when the circuit board 100 needs to be fixed, the second fixing seat 122 can pass through the second aperture plate 114 and the opening 101 of the circuit board 100 and abut against the first aperture plate 113, another fixing member (such as a screw, not shown) can pass through the first opening 113a and be locked on the second fixing seat 122 of the housing assembly 120, the first aperture plate 113 abuts against the abutting surface 122a and is attached to the abutting surface 122a as much as possible, so that the circuit board 100 can be parallel to the inclined surface 125.

Referring to fig. 2A to 3B, the housing component 120 has an inclined surface 125 and an upright surface (not labeled) connected thereto. When the display is laid flat on the desktop, the inclined plane 125 and the vertical plane are both perpendicular to the desktop, while the vertical plane is parallel to the display surface of the display. In practice, the inclined surface 125 and the vertical surface connected thereto in the housing assembly 120 of different displays may have different included angles, which may be referred to as an inclined angle θ of the inclined surface 125 (see fig. 2B and 3B). Generally, the inclination angle θ of the inclined planes 125 of different displays is within 10 °, for example, the inclination angle θ is between 25 ° and 35 °. When the fixing assembly 110 and the housing assembly 120 are assembled, the first folding plate 111 is attached to the abutting surface 121a of the first fixing seat 121, the first aperture plate 113 is attached to the abutting surface 122a of the second fixing seat 122, and the circuit board 100 is parallel or substantially parallel to the inclined surface 125, if the abutting surface 121a and the abutting surface 122a are both parallel to the vertical surface, it can be considered that the first adapting angle θ 1 of the first folding plate 111 relative to the circuit board 100 at this time is equal to the current inclination angle θ, for example, 25 °; the second fitting angle θ 2 of the first aperture plate 113 with respect to the circuit board 100 is also equal to the current inclination angle θ, for example, 25 °.

In manufacturing the fixing assembly 110 for such a display, the initial bending angles of the first folding plate 111 and the second folding plate 112 can be defined by combining the range of the inclination angle θ and the feature that the second hole plate 114 is parallel to the circuit board 100. Generally, the first initial angle and the second initial angle may both be selected as an intermediate value within a range of selecting the inclination angle θ, for example, 30 °, so that regardless of the inclination angle θ, a difference between the first initial angle and the first adaptive angle θ 1 is less than or equal to half of a difference between the ranges of values of the inclination angle θ, which is convenient for operation.

Examples are: with the inclination angle θ being 25 ° and the abutting surfaces 121a and 122a both being parallel to the vertical surface, the first initial angle and the second initial angle are both 30 °, the first adaptive angle θ 1 and the second adaptive angle θ 2 are both 25 °, before the fixing assembly 110 is fixed to the first fixing seat 121 and the second fixing seat 122, an included angle between the first folding plate 111 and the abutting surface 121a of the first fixing seat 121 and an included angle between the first aperture plate 113 and the abutting surface 122a of the second fixing seat 122 are equal to 5 °, and subsequently, the bending of the first folding plate 111 and the first aperture plate 113 is only fine-tuned, thereby facilitating the operation.

Referring to fig. 1A and fig. 1B, a module 102 is disposed on the circuit board 100, for example, the module 102 is a USB power supply module or other interface modules, which is not limited in the present invention. The insertion end 103 of the module 102 may protrude from the surface of the circuit board 100 to be correspondingly exposed in the slot 123 of the housing assembly 120, as shown in fig. 4. That is, from the appearance, the module 102 is accommodated in the housing assembly 120, only the insertion end 103 is exposed in the slot 123, the module 102 is a USB slot, and the slot 123 is a USB opening on the housing assembly 120.

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

Referring to fig. 2A and 2B, the first fixing seat 121 and the second fixing seat 122 are disposed on the inclined surface 125 and form a height difference with respect to an upright surface connected to the inclined surface 125, and further, it can be understood that the abutting surface 121a of the first fixing seat 121 and the abutting surface 122A of the second fixing seat 122 have a height difference with respect to the upright surface.

In an embodiment, the first fixing seat 121 is closer to the edge of the display than the second fixing seat 122, so that the space occupied by the position of the first fixing seat 121 is smaller than the space occupied by the position of the second fixing seat 122, and thus the height H1 of the first fixing seat 121 relative to the inclined surface 125 is lower than the height H2 of the second fixing seat 122 relative to the inclined surface 125, for example, or when there is sufficient space, the height H1 of the first fixing seat 121 relative to the inclined surface 125 is equal to the height H2 of the second fixing seat 122 relative to the inclined surface 125, for example, which may affect the height difference between the contact surface 121a and the contact surface 122a in different displays.

In practical applications, because the tilt angles θ of the different displays are different and the fixing bases at different positions can occupy different spaces according to the positions, when the vertical surface is placed on the horizontal supporting surface, the height difference between the first fixing base 121 and the second fixing base 122 on the inclined surface 125 of the different displays relative to the vertical surface (or the horizontal supporting surface) can be different, which can be specifically understood as the height difference between the interference surface 121a and the interference surface 122a relative to the horizontal supporting surface. By adopting the fixing element 110 of the present application, the first folding plate 111 and the second folding plate 112 can be freely bent, so as to facilitate the fixing connection between the fixing element and the first fixing seat 121/the second fixing seat 122, thereby improving the universality of the fixing element 110.

When the fixing assembly 110 is assembled on the first fixing base 121 and the second fixing base 122, the first folding plate 111 is matched with the first fixing base 121 and fixed on the contact surface 121a of the first fixing base 121, and the second folding plate 112 is matched with the second fixing base 122 and fixed on the contact surface 122a of the second fixing base 122.

It should be noted that, in the present invention, when the fixing assembly 110 is assembled with the circuit board 100, the first folding plate 111 has a first initial angle relative to the circuit board 100, and the first hole plate 113 has a second initial angle relative to the circuit board 100; when the fixing assembly 110 and the housing assembly 120 are assembled, the first flap 111 has a first fitting angle θ 1 with respect to the circuit board 100, and the first aperture plate 113 has a second fitting angle θ 2 with respect to the circuit board 100. Further, the first fitting angle θ 1 between the first folding plate 111 and the circuit board 100 and the second fitting angle θ 2 between the second folding plate 112 and the circuit board 100 are both related to the inclination angle θ of the inclined plane 125, for example, when the inclination angle θ of the inclined plane 125 is 25 degrees, the first initial angle between the first folding plate 111 and the circuit board 100 can be adjusted to the first fitting angle θ 1 (for example, 25 degrees equal to the current inclination angle θ) matching the current inclination angle θ by bending the angle of the first folding plate 111, and the second initial angle between the second folding plate 112 and the circuit board 100 can be adjusted to the second fitting angle θ 2 (for example, 25 degrees equal to the current inclination angle θ) matching the current inclination angle θ by bending the angle of the second folding plate 112; when the inclination angle θ of the inclined plane 125 is 30 degrees, a first initial angle between the first folding plate 111 and the circuit board 100 may be adjusted to a first adaptive angle θ 1 (e.g., 30 degrees equal to the current inclination angle θ) matching the current inclination angle θ by bending the angle of the first folding plate 111, and a second initial angle between the second folding plate 112 and the circuit board 100 may be adjusted to a second adaptive angle θ 2 (e.g., 30 degrees equal to the current inclination angle θ) matching the current inclination angle θ by bending the angle of the second folding plate 112. 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 also changes, and therefore the first folding plate 111 and the second folding plate 112 must be properly bent to adjust the first fitting angle θ 1 and the second fitting angle θ 2 according to the height difference.

In an embodiment, the abutting surface 121a is parallel to the abutting surface 122a, and the first folding plate 111 is parallel to the first hole plate 113, so that the first initial angle is equal to or substantially equal to the second initial angle, and the first fitting angle θ 1 is equal to or substantially equal to the second fitting angle θ 2, but the first fitting angle θ 1 may be larger than or smaller than the second fitting angle θ 2, which can be adjusted according to practical situations, which is not limited in the present invention.

Referring to fig. 3A and 3B, the fixing element 110 is assembled on the circuit board 100 for fixing the circuit board 100 on the first fixing seat 121 and the second fixing seat 122 of the housing element 120, and the fixing element 110 can be used as an electromagnetic wave shielding element of the circuit board 100 to reduce electromagnetic wave radiation. In the present embodiment, the circuit board 100 is assembled on the inclined surface 125 of the housing assembly 120, and the circuit board 100 is parallel or substantially parallel to the inclined surface 125, so that the modules 102 on the circuit board 100 can be disposed perpendicular to the inclined surface 125.

In order to make the circuit board 100 parallel or substantially parallel to the inclined surface 125, the second hole plate 114 is supported under the circuit board 100, and the second hole plate 114 is parallel or substantially parallel to the circuit board 100.

The steps of assembling and fixing are as follows:

step A, assembling the fixing component 110 and the circuit board 100;

step B, the vertical surface is placed on the horizontal bearing surface, and the inclined surface 125, the vertical surface and the horizontal bearing surface have an inclined angle theta; wherein the sequence of the step A and the step B can be interchanged;

and step C, placing the fixing component 110 together with the circuit board 100 at a designated position on the shell component 120. Specifically, since the vertical surface is disposed on the horizontal bearing surface, the interference surface 121a of the first fixing seat 121 and the interference surface 122a of the second fixing seat 122 on the inclined surface 125 are parallel to the vertical surface (i.e., parallel to the horizontal bearing surface). The assembler places the fixing assembly 110 together with the circuit board 100 at a designated position along the vertical direction, so that the first fixing seat 121 abuts against the first folded plate 111, and the second fixing seat 122 passes through the second hole plate 114 and the opening of the circuit board 100 to abut against the first hole plate 113;

and D, fixing the first orifice plate 113 and the second fixed seat 122. Specifically, the first orifice plate 113 and the second fixing seat 122 may be directly fixed by a fixing member (e.g., a screw), and in the fixing process, the first orifice plate 113 is bent due to a force so as to gradually adhere to the abutting surface 122 a. Or, the first orifice plate 113 is bent to the second adaptive angle θ 2 to be attached to the abutting surface 122a, and then the first orifice plate 113 and the second fixing seat 122 are fixed by using the fixing member.

Since the first orifice plate 113 and the second orifice plate 114 have the second initial angle θ 2 therebetween, while the second orifice plate 114 is parallel to the circuit board 100. Generally, the second initial angle θ 2 is a middle value of a range of values of the inclination angles θ of the inclined surfaces 125 of different displays, and the difference of the different inclination angles θ is not very large (for example, within 10 °), so that when the first aperture plate 113 is gradually bent to be attached to the contact surface 122a, the circuit board 100 is gradually parallel to the inclined surfaces 125 together with the second aperture plate 114 along with the bending of the first aperture plate 113, and when the first aperture plate 113 is attached to the contact surface 122a, the angle between the second aperture plate 114 and the inclined surfaces 125 is less than a half of the difference (for example, within 0 to 5 °), the second aperture plate 114 can be considered to be parallel or substantially parallel to the inclined surfaces 125, so that the circuit board 100 is parallel or substantially parallel to the inclined surfaces 125. In other words, the process of fixing the first aperture plate 113 and the second fixing base 122 can fix the first aperture plate 113 and the second fixing base 122, and at the same time, the circuit board 100 can be parallel or substantially parallel to the inclined surface 125, thereby facilitating the subsequent user to use the module 102 on the circuit board 100.

And E, bending the first folding plate 111 to a first adaptive angle theta 1 to enable the first folding plate to be attached to the abutting surface 122a, and fixing the first folding plate 111 and the first fixed seat 121 by using a fixing piece. Before first folded plate 111 buckles, first folded plate 111 has first initial angle theta 1 between with circuit board 100, because the intermediate value of the value range of first initial angle theta 1 can take the inclination angle theta to, both contained angles are less than half of the difference (for example in 0 ~ 5) when first folded plate 111 butt conflict face 121a, thereby first folded plate 111 only need buckle less angle, the equipment of being convenient for.

In addition, referring to fig. 3A and fig. 3B, the housing assembly 120 further includes two limiting members 124, and the two limiting members 124 are located at two opposite sides of the circuit board 100 to limit the horizontal movement of the circuit board 100 relative to the housing assembly 120, so as to ensure the quality of assembly. In addition, two recesses 104 are disposed on two opposite sides of the circuit board 100 for accommodating two position-limiting members 124. In addition, the surface of the circuit board 100 rests on the two stoppers 124, so that the circuit board 100 is separated from the housing assembly 120 by a predetermined distance, for example, about the height of the module 102, so 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.

In summary, the fixing structure of the circuit board according to the above embodiments of the 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. Because different display shells can not form the fixed seats with the same height difference on the inclined surfaces, the fixed components suitable for the circuit board must be manufactured aiming at different shells in the prior art. Meanwhile, the fixing structure of the circuit board can improve the assembly quality of the circuit board and reduce the assembly tolerance.
