DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] refer to Fig.12 and Fig.13In the related art, the circuit board usually includes two kinds of openings, namely, the board connection opening 910 and the substrate connection opening 920. The board connection opening 910 is used to connect the circuit board with other devices to form a board by screws, and the substrate connection opening 920 is used to connect the board with the substrate 410 by screws to fix the board. The number of the board connection openings 910 and the number of the substrate connection openings 920 are usually equal, resulting in the need to open too many openings on the circuit board, affecting the integrity of the circuit board structure, thereby reducing the reliability of the board structure, and the opening design and processing are also relatively complicated. At the same time, if Fig.13 As shown, when the holes are densely packed and two holes are close to each other, it may cause the screws to be removed by mistake.

[0039] For the above questions, refer to Figures 1 to 9 The utility model provides a board structure, including:

[0040] The circuit board 100 is provided with at least one first connection hole 110;

[0041] The structural assembly 200 is provided with a second connection hole corresponding to the first connection hole 110;

[0042] A hollow screw 300, wherein the hollow screw 300 is passed through the first connection hole 110 and is threadedly connected to the second connection hole, or the hollow screw 300 is passed through the second connection hole and is threadedly connected to the first connection hole 110, so as to fix the circuit board 100 and the structural assembly 200 to form a board card;

[0043] The hollow screw 300 is provided with a hollow channel 301 , and the hollow channel 301 is used to allow a fixing member to pass through so as to fix the board and the substrate assembly 400 .

[0044] The circuit board 100 is provided with a first connection hole 110, and the structural assembly 200 is provided with a second connection hole corresponding to the first connection hole 110. The circuit board 100 and the structural assembly 200 are fixed to form a board card by the structure that the hollow screw 300 passes through the first connection hole 110 and is threadedly connected to the second connection hole, or the hollow screw 300 passes through the second connection hole and is threadedly connected to the first connection hole 110. At the same time, the hollow screw 300 is provided with a hollow channel 301, allowing a fixing member to pass through, such as a fixing screw 500 or a snap member, etc., passing through the hollow channel 301, and the fixing member can fix the board card and the substrate assembly 400.

[0045] In this way, the structure of the first connecting hole 110, the second connecting hole and the hollow screw 300 is utilized to fix the circuit board 100 and the structural component 200 to form a board card. Meanwhile, through the hollow channel 301, the first connecting hole 110 and the second connecting hole can be reused to fix the circuit board 100 and the structural component 200, i.e., the board card, to the substrate component 400. This helps to reduce the number of openings on the circuit board 100 and the structural component 200, improve the structural reliability of the board card and simplify the opening design. Meanwhile, the reduction in the number of openings also helps to reduce the probability of accidental disassembly due to overly dense openings.

[0046] Based on the two hole classifications of the above-mentioned board-card connection openings and substrate connection openings, the first connection hole 110 and the second connection hole in the utility model are equivalent to being used as board-card connection openings and substrate connection openings at the same time, that is, based on the structure of the first connection hole 110, the second connection hole and the hollow screw 300, the first connection hole 110 and the second connection hole can be used to connect and fix the circuit board 100 and the structural component 200 to form a board, and at the same time, the board and the substrate component 400 can be connected, so that the number of openings on the circuit board 100 can be reduced by half.

[0047] It is understandable that, according to the requirement of fixing stability, the circuit board 100 may be provided with a plurality of first connection holes 110, and the number of the first connection holes 110 and the number of the second connection holes are equal to the number of the hollow screws 300. The circuit board 100 is provided with a plurality of electronic devices, such as chips, capacitors, resistors and other devices.

[0049] refer to Figure 1 and Figure 5 In some embodiments of a board structure of the utility model, the structural component 200 includes an upper structural member 210 and a lower structural member 220, one of the upper structural member 210 and the lower structural member 220 is provided with a first through hole, and the other is provided with the second connecting hole, the circuit board 100 is located between the upper structural member 210 and the lower structural member 220, the hollow screw 300 is passed through the first through hole and the first connecting hole 110, and the hollow screw 300 is threadedly connected to the second connecting hole.

[0050] As a fixed method, refer to Figure 1The lower structure 220 is provided with a first through hole and the upper structure 210 is provided with a second connecting hole. The hollow screw 300 passes through the first through hole of the lower structure 220 and the first connecting hole 110 of the circuit board 100 from bottom to top and is threadedly connected with the second connecting hole of the upper structure 210 to fix the lower structure 220, the circuit board 100 and the upper structure 210 to form a board.

[0051] As another way to fix it, refer to Figure 5 The upper structure 210 is provided with a first through hole and the lower structure 220 is provided with a second connecting hole. The hollow screw 300 passes through the first through hole of the upper structure 210 and the first connecting hole 110 of the circuit board 100 from top to bottom and is threadedly connected with the second connecting hole of the lower structure 220 to fix the lower structure 220, the circuit board 100 and the upper structure 210 to form a board.

[0052] In this way, the positions of the first through hole and the second connecting hole can be set according to the requirements of the design application, so that the hollow screw 300 can be inserted in a required direction for fixed installation.

[0053] It can be understood that, when the second connecting hole is threadedly connected to the hollow screw 300 , the second connecting hole is provided with a corresponding internal thread, that is, the second connecting hole is a threaded hole.

[0054] In some embodiments of the present invention, the upper structure 210 may include an implementation of a device such as a heat sink and a protective cover, and the lower structure 220 may include an implementation of a device such as a support plate.

[0055] In some embodiments of the present invention, the structural assembly 200 may also include only the upper structural member 210, and the hollow screw 300 may pass through the second connection hole on the upper structural member 210 and be threadedly connected to the first connection hole 110. In this case, the first connection hole 110 is set as a threaded hole and the second connection hole is set as a through hole. The first connection hole 110 and the second connection hole may be set as a through hole or a threaded hole according to the connection requirements.

[0056] refer to Figures 2 to 4 and Figures 6 to 8 In some embodiments of a board structure of the present invention, the hollow screw 300 includes a head 310 and a rod 320 , the hollow channel 301 passes through the head 310 and the rod 320 , and the rod 320 is provided with an external thread 321 .

[0057] When the hollow screw 300 passes through the lower structure 220, the circuit board 100 and the upper structure 210 in sequence, the head 310 of the hollow screw 300 presses against the lower structure 220 and the rod 320 is threadedly connected with the second connection hole of the upper structure 210 through the external thread 321; when the hollow screw 300 passes through the upper structure 210, the circuit board 100 and the lower structure 220 in sequence, the head 310 of the hollow screw 300 presses against the upper structure 210 and the rod 320 is threadedly connected with the second connection hole of the lower structure 220 through the external thread 321. In this way, the upper structure 210 and the lower structure 220 are close to each other to clamp the circuit board 100, achieving a fixing effect.

[0058] refer to Figures 2 to 4 In some embodiments of the present invention, the head 310 is provided with a hexagonal recess 311 , and the bottom of the hexagonal recess 311 is connected to the hollow channel 301 .

[0059] The head 310 of the hollow screw 300 is provided with a hexagonal recess 311 , and the hollow screw 300 can be driven to rotate by a device such as an inner hexagonal wrench, thereby making the external thread 321 on the rod 320 threadedly connected.

[0060] In some embodiments of the present invention, the head of the hollow screw 300 may also be provided with other polygonal recesses such as a quadrangular recess and a pentagonal recess.

[0061] refer to Figures 6 to 8 In some embodiments of the present invention, the outer edge of the head 310 is in an equilateral hexagonal shape.

[0062] Since the outer edge of the head 310 of the hollow screw 300 is in an equilateral hexagonal shape, the hollow screw 300 can be driven to rotate by a device such as an external hexagonal wrench, thereby making the external thread 321 on the rod 320 threadedly connected.

[0063] In some embodiments of the present invention, the head of the hollow screw 300 may also be in the shape of a rectangle, an equilateral pentagon or other polygonal shapes.

[0064] refer to Figure 1 In some embodiments of the utility model, the first through hole is arranged on the lower structure 220, the second connecting hole is arranged on the upper structure 210, the lower structure 220 is provided with a sink, the bottom of the sink is connected with the first through hole, the head 310 is pressed against the lower structure 220 and the head 310 is located in the sink, the rod 320 is passed through the first through hole, the first connecting hole 110 and the second connecting hole, and the external thread 321 is threadedly connected with the second connecting hole.

[0065] Since the lower structure 220 needs to fit with the substrate assembly 400 when fixing the board, when the hollow screw 300 is inserted from bottom to top, it is necessary to prevent the head 310 of the hollow screw 300 from protruding from the lower surface of the lower structure 220 to prevent the head 310 from affecting the fit and damaging the substrate assembly 400. By providing a sink groove on the lower structure 220 to accommodate the head 310 of the hollow screw 300, when the hollow screw 300 fixes the upper structure 210, the circuit board 100 and the lower structure 220, the head 310 will not protrude from the lower structure 220, which is conducive to ensuring that the lower surface of the lower structure 220 can fit with the substrate assembly 400, avoiding damage to the substrate assembly 400 and improving structural reliability.

[0066] refer to Figure 1 and Figure 4 In some embodiments of the present invention, the rod portion 320 is provided with a guiding slope 322 , and the guiding slope 322 is located on the opening edge of the hollow channel 301 formed on the rod portion 320 .

Figure 1 As shown, a guiding bevel 322 is provided on the rod portion 320, and the guiding bevel 322 is located on the opening edge of the rod portion 320 formed by the hollow channel 301. Therefore, when the fixing screw 500 is subsequently extended into the hollow channel 301 from top to bottom, even if the rod portion 320 does not pass through the upper surface, the fixing screw 500 can be pressed against the guiding bevel 322 and accurately extended into the hollow channel 301, that is, the guiding bevel 322 can guide the fixing screw 500 to pass through the hollow channel 301, which is conducive to making the installation operation easier.

In this way, the hollow screw 300 and the fixing screw 500 are both inserted from top to bottom and can be operated on the same side, which is conducive to making the installation operation more convenient.
