[0003] Laptop PCBA boards are generally quite complex and often difficult to repair after damage. In such cases, motherboard replacement is necessary. The dimensions of a laptop's PCBA board are typically designed based on the laptop's casing. When the laptop model is older or rarer, it's often difficult to find a PCBA board that is compatible with the original casing. In this situation, a different model of PCBA board is used as a substitute. However, the mounting holes or component placement on other PCBA boards may differ from the laptop casing, leading to installation difficulties.

[0004] Therefore, this application proposes a laptop PCBA board angle adjustment bracket to adapt the PCBA board to the laptop casing. Utility Model Content

[0037] like Figures 1-3 As shown, this utility model provides a laptop PCBA board angle adjustment bracket, including a laptop casing connecting mechanism 1, a PCBA board support mechanism 2, and fasteners 3. The laptop casing connecting mechanism 1 connects to the PCBA board mounting holes on the laptop casing. The PCBA board support mechanism 2 supports the PCBA board. The PCBA board support mechanism 2 is mounted on the upper end of the laptop casing connecting mechanism 1, and the PCBA board support mechanism 2 can rotate to adapt to the position of the mounting holes for different types of PCBA boards. After the PCBA board support mechanism 2 is adjusted to the correct angle, it can be fixed in place by fixing the fasteners 3 to the end of the laptop casing connecting mechanism 1. When installing the PCBA board, one or more adjustment brackets can be used to fix the PCBA board in place with the mounting holes on the laptop casing, or all adjustment brackets can be used to support the PCBA board.

[0038] The laptop casing connection mechanism 1 includes a support column 11, which raises the overall height of the adjustment bracket to prevent the bottom of the PCBA board from touching the inner wall of the laptop, thus improving heat dissipation. A threaded post 12 is provided at the bottom of the support column 11, which connects to the existing PCBA board mounting holes on the laptop casing, fixing the entire adjustment bracket to the laptop casing. A limiting post 13 is provided at the top of the support column 11, with a fixing threaded hole 14 at its axis. The PCBA board support mechanism 2 is sleeved on the outer surface of the limiting post 13, and fasteners 3 are threaded into the fixing threaded hole 14 to provide angular positioning for the PCBA board support mechanism 2. Furthermore, after disassembling the PCBA board support mechanism 2, the PCBA board can be directly placed on the limiting post 13 and secured directly using the fasteners 3, further enhancing the versatility of PCBA board installation methods.

[0039] like Figures 1-4 As shown, in some embodiments, the support column 11 of this utility model is a rhomboid column to facilitate installation by fingers or tools. The threaded column 12 and the limiting column 13 are both located at the axis of the support column 11, which can improve the center of gravity and stability of the PCBA board support mechanism 2 after installation.

[0040] like Figure 2 and Figure 3 As shown, in some embodiments, the PCBA board support mechanism 2 of this utility model includes a connecting ring 21, which is a disc with a diameter not greater than that of the support column 11. A mounting hole 22 is provided at the center of the connecting ring 21, and the mounting hole 22 is fitted onto the outer surface of the limiting column 13. The connecting ring 21 can be fixed to the threaded hole 14 as an axis for rotational angle adjustment. After the connecting ring 21 has been adjusted to the desired angle, the top of the mounting hole 22 is fixed and limited by the fastener 3 by tightening the fastener 3 against it.

[0041] The connecting ring 21 has an outwardly extending extension strip 23 on its side, and an adjustable cable tray 24 is provided at the end of the extension strip 23. The adjustable cable tray 24 has PCBA board fixing holes 25. When installing the PCBA board, the PCBA board is placed on the adjustable cable tray 24 and fixed by bolts passing through the PCBA board fixing holes 25.

[0042] like Figure 4 and Figure 5 As shown, in some embodiments, the end of the extension strip 23 of this invention is provided with a telescopic groove 231 extending into the extension strip 23, and the adjustable cable tray 24 is disposed inside the telescopic groove 231, and the adjustable cable tray 24 can extend and retract within the telescopic groove 231. By extending and retracting the adjustable cable tray 24, the adjustment frame can be adapted to more types of PCBA boards.

[0043] like Figure 6As shown, in some embodiments, the adjustable cable tray 24 of this utility model includes a connecting slider 241, which is a strip-shaped structure with the same length as the telescopic groove 231. One end of the connecting slider 241 is inserted into the interior of the telescopic groove 231, and the connecting slider 241 can slide inside the telescopic groove 231 to achieve the effect of length adjustment. The other end of the connecting slider 241 is provided with a PCBA board support platform 242 to support the PCBA board, and PCBA board fixing holes 25 are formed on the PCBA board support platform 242 to cooperate with bolts to fix the PCBA board.

[0044] like Figure 4 and Figure 6 As shown, in some embodiments, the outer surface of the connecting slider 241 is tightly fitted to the inner wall of the telescopic groove 231 to prevent the connecting slider 241 from wobbling inside the telescopic groove 231. A limiting member is provided at one end of the connecting slider 241 located inside the telescopic groove 231 to limit the maximum extension length of the connecting slider 241 and prevent it from falling out of the telescopic groove 231. The outer surface of the PCBA board support 242 is flush with the outer surface of the extension strip 23, which limits the storage depth of the connecting slider 241. Simultaneously, after the connecting slider 241 is stored, the connection between the PCBA board support 242 and the extension strip 23 remains smooth, improving the feel when handling it.

[0045] like Figure 5 and Figure 6 As shown, in some embodiments, the inner wall of the telescopic groove 231 of this utility model is provided with a plurality of raised diamond-shaped ribs 232, which can increase the compressive strength and deformation resistance of the hollow extension strip 23. The outer surface of the connecting slider 241 is provided with a limiting groove 243 that matches the position and number of the diamond-shaped ribs 232, so as to avoid the diamond-shaped ribs 232 interfering with the extension and retraction of the connecting slider 241.

[0046] The cross-section of the limiting slide groove 243 is adapted to the cross-section of the rhomboid rib 232, and the inner wall of the limiting slide groove 243 is in contact with the outer surface of the rhomboid rib 232. This increases the contact area between the connecting slider 241 and the inside of the telescopic groove 231. At the same time, the cooperation between the rhomboid rib 232 and the limiting slide groove 243 helps the connecting slider 241 maintain better stability when sliding.

[0047] In summary, the PCBA board angle adjustment bracket of this utility model connects to the threaded holes inside the laptop casing via threaded post 12. Then, the angle of the PCBA board support mechanism 2 is adjusted according to the position of the PCBA board mounting holes, and the angle of the PCBA board support mechanism 2 is positioned by fasteners 3. Finally, multiple adjustment brackets support the periphery of the PCBA board, and bolts are threaded through the mounting holes on the PCBA board and threadedly connected to the PCBA board fixing holes 25 for fixation. This achieves the effect of enabling laptops to adapt to different models of PCBA boards.

[0048] This invention allows each adjustment bracket to be on the same or different horizontal planes by adjusting the connection depth between the threaded post 12 and the laptop casing, so as to adapt to different models and types of PCBA boards. Furthermore, a ventilation and heat dissipation gap can be left between the bottom of the PCBA board and the inner wall of the laptop.

[0049] This utility model provides a telescopic groove 231 at the end of the extension strip 23, and the adjustable cable tray 24 is inserted into the telescopic groove 231, so that the length of the adjustable cable tray 24 can be adjusted, thereby enabling the adjustable bracket to adapt to more types of PCBA boards.

[0050] This invention provides multiple rhomboid ribs 232 inside the telescopic groove 231 and a limiting groove 243 adapted to the rhomboid ribs 232 on the connecting slider 241. When the extension bar 23 is under force, the rhomboid ribs 232 can increase the extension bar 23's resistance to deformation and bending. At the same time, the cooperating rhomboid ribs 232 and limiting groove 243 can ensure the stability of the extension and retraction of the connecting slider 241.

[0051] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0052] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
