Referring to FIGS. 1 to 4 , an embodiment of the present invention provides a circuit board mounting structure, including a circuit board body 510, a mounting seat 100, a locking seat 200, an assembly frame 300, and a locking mechanism 400. The mounting seat 100 is provided with a mounting position 110 and a mounting opening 120 that are connected to each other; the locking seat 200 is provided on a side of the mounting seat 100 where the mounting opening 120 is provided; and the assembly frame 300 is provided with a locking mechanism 400. The mounting frame 300 is provided with an assembly portion 310, and the circuit board body 510 is provided on the mounting frame 300. The mounting frame 300 can enter and exit the mounting position 110 through the mounting opening 120; the locking mechanism 400 is used to be provided on a side of the mounting seat 100 where the mounting opening 120 is provided and to be locked or unlocked with the locking seat 200, and the assembly portion 310 is used to be clamped between the locking seat 200 and the locking mechanism 400.

In the above circuit board mounting structure, the assembly frame 300 can be mounted on the mounting position 110 through the mounting opening 120 of the mounting seat 100, and the lock seat 200 and the locking mechanism 400 arranged on the side of the mounting seat 100 corresponding to the mounting opening 120 can clamp the assembly portion 310 on the assembly frame 300. At this time, the lock seat 200 and the locking mechanism 400 are locked, thereby realizing the installation between the circuit board body 510 and the mounting seat 100; when it is necessary to install the circuit board body 510 on the mounting seat When the circuit board body 510 on 100 is disassembled, the lock base 200 and the locking mechanism 400 are unlocked, so that the lock base 200 and the locking mechanism 400 cancel the clamping of the assembly part 310, so that the assembly frame 300 on the mounting position 110 is smoothly taken out from the mounting port 120, and then the circuit board body 510 is taken out; compared with the traditional technology, when the user adopts the above-mentioned circuit board mounting structure to disassemble and assemble the circuit board body 510, the process is more convenient and the disassembly and assembly efficiency is high.

In addition, by installing the circuit board body 510 at the mounting position 110 of the mounting base 100 and then installing the mounting base 100 at the corresponding position of the server case, the mounting base 100 can provide a certain degree of protection for the circuit board body 510 and prevent other components in the server from colliding with the circuit board body 510.

As an explanation, please refer to Figures 2 to 4. The assembly frame 300 enters the mounting position 110 through the mounting opening 120 of the mounting seat 100 so that the assembly portion 310 abuts against the lock seat 200, and then the locking mechanism 400 abuts against the side of the assembly portion 310 away from the lock seat 200 and locks with the lock seat 200, thereby achieving the installation between the assembly frame 300 and the mounting seat 100 on the circuit board body 510.

In one embodiment, the circuit board body 510 is a host bus adapter (commonly known as HBA, Host Bus Adapter), which is used to electrically connect to the server motherboard. The HBA adopts hot-swap technology to facilitate disassembly and assembly, improve disassembly and assembly efficiency, and significantly shorten operation and maintenance time.

Furthermore, the circuit board mounting structure can also be used to assemble an expansion card 520 (also known as an adapter card, riser card, etc.), the HBA is used to electrically connect to the expansion card 520, and the expansion card 520 is used to electrically connect to the server motherboard module 720 to achieve electrical connection between the HBA and the motherboard module 720.

Specifically, the expansion card 520 is used to be installed on a side of the mounting seat 100 away from the mounting port 120. When the mounting frame 300 is installed on the mounting position 110, the HBA on the mounting frame 300 is electrically connected to the expansion card 520. Then, the mounting seat 100 is installed in the server chassis 710, so that the expansion card 520 on the mounting seat 100 is electrically connected to the server motherboard, thereby realizing the electrical connection between the HBA and the motherboard module 720.

Please refer to FIG. 3 . Furthermore, the expansion card 520 is connected to the mounting base 100 by screws. The upper portion of the mounting base 100 is hollowed out so that when the mounting position 110 is arranged corresponding to the mainboard module 720 , it is convenient for the expansion card 520 to be electrically connected to the mainboard module 720 .

In some embodiments, the locking mechanism 400 is detachably disposed on a side of the mounting base 100 corresponding to the mounting opening 120. The locking mechanism 400 can be installed on a side of the mounting base 100 corresponding to the mounting opening 120 and locked with the lock base 200 so that the assembly portion 310 is sandwiched between the lock base 200 and the locking mechanism 400. The locking mechanism 400 can also be detached from the side of the mounting base 100 corresponding to the mounting opening 120 to release the assembly portion 310; in other embodiments, the locking mechanism 400 can be movably disposed on the side of the mounting base 100 corresponding to the mounting opening 120. Similar to the above-mentioned embodiment, the locking mechanism 400 can be moved to lock or unlock with the locking base 200, which will not be repeated here.

Please refer to FIG. 4 . In one embodiment, the mounting base 100 is further provided with a heat dissipation hole 140 . The heat dissipation hole 140 can reduce the overall weight of the mounting base 100 while ensuring the heat dissipation effect of the circuit board body 510 .

Please refer to Figures 1 to 4. In one embodiment, the locking mechanism 400 includes a cover body 410 and a pressing portion 420. The cover body 410 is rotatably disposed on a side of the mounting seat 100 where the mounting opening 120 is opened. The pressing portion 420 is disposed on the cover body 410. The assembly portion 310 is used to be clamped between the locking seat 200 and the pressing portion 420.

The cover 410 can be rotated to open or close the mounting opening 120. The pressing portion 420 disposed on the cover 410 can be rotated together with the cover 410. After the mounting frame 300 is mounted on the mounting position 110 through the mounting opening 120, one side of the mounting portion 310 abuts against the lock seat 200. The cover 410 rotates to close the mounting opening 120. At this time, the pressing portion 420 rotates to the side of the mounting portion 310 away from the lock seat 200, so as to clamp the mounting portion 310 on the lock seat 200. The cover 410 is rotated to open the mounting opening 120, and the pressing portion 420 is rotated to move away from the assembly portion 310, so that the assembly portion 310 is released, and then the assembly frame 300 on the mounting position 110 is taken out from the mounting opening 120; with this arrangement, the disassembly and assembly process is convenient and the disassembly and assembly efficiency is high.

Please refer to Figures 1 to 3. In one embodiment, the locking mechanism 400 further includes a first locking body 430, which is disposed on the pressing portion 420 and is used to lock or unlock with the lock base 200; wherein the first locking body 430 is locked with the lock base 200, and the assembly portion 310 is sandwiched between the lock base 200 and the pressing portion 420.

After the assembly frame 300 is installed on the mounting position 110 through the mounting opening 120, one side of the assembly portion 310 abuts against the lock seat 200, the cover 410 rotates to close the mounting opening 120, and the first lock body 430 provided on the pressing portion 420 is locked and matched with the lock seat 200 to clamp the assembly portion 310 between the lock seat 200 and the pressing portion 420; when it is necessary to install the assembly frame 300 on the mounting seat 100, the assembly portion 310 is installed on the mounting seat 100. When the circuit board body 510 on the mounting position 110 is to be disassembled, the first lock body 430 and the lock base 200 are unlocked, the cover body 410 is rotated to open the mounting opening 120, the pressing portion 420 is rotated and moves away from the assembly portion 310, so that the assembly portion 310 is released, and then the assembly frame 300 on the mounting position 110 is taken out from the mounting opening 120; in this way, the disassembly and assembly process is convenient and the disassembly and assembly efficiency is high.

Optionally, the first lock body 430 and the lock base 200 can be locked or unlocked by snapping together, or by putting a lock sleeve on the first lock body 430 and the lock base 200 to achieve locking or unlocking, which is not specifically limited here.

Please refer to Figures 1 to 3. In one embodiment, the first lock body 430 includes a first threaded component 431, the pressing portion 420 is provided with a first mounting hole 421, the assembly portion 310 is provided with a second mounting hole 311, the lock seat 200 is provided with a first threaded hole 210, and the first threaded component 431 is penetrated through the first mounting hole 421 and the second mounting hole 311 and is threadedly connected to the first threaded hole 210.

The first threaded member 431 passes through the first mounting hole 421 of the pressing portion 420 and the second mounting hole 311 of the assembling portion 310, and can be threadedly connected with the first threaded hole 210 on the lock seat 200 to achieve locking cooperation between the pressing portion 420 and the lock seat 200; such a configuration is low in cost and easy to operate, thereby improving disassembly and assembly efficiency.

Optionally, the first threaded component 431 may be a common threaded component such as a bolt or a screw, which is not specifically limited herein.

Please refer to Figures 1 to 3. In one embodiment, the locking mechanism 400 further includes a second locking body 440, which is disposed on the cover 410 and is used to lock or cooperate with the mounting seat 100; wherein the second locking body 440 is locked and cooperated with the mounting seat 100, and the assembly portion 310 is sandwiched between the locking seat 200 and the pressing portion 420.

After the mounting frame 300 is installed on the mounting position 110 through the mounting opening 120, one side of the mounting portion 310 abuts against the lock seat 200, the cover 410 rotates to close the mounting opening 120, and the second lock body 440 disposed on the cover 410 is locked and matched with the mounting seat 100 to clamp the mounting portion 310 between the lock seat 200 and the pressing portion 420; when the mounting portion 100 is installed, the mounting portion 310 is clamped between the lock seat 200 and the pressing portion 420. When the circuit board body 510 on the mounting position 110 is to be disassembled, the second lock body 440 and the mounting seat 100 are unlocked, the cover body 410 is rotated to open the mounting opening 120, the pressing part 420 is rotated and moves away from the assembly part 310, so that the assembly part 310 is released, and then the assembly frame 300 on the mounting position 110 is taken out from the mounting opening 120; in this way, the disassembly and assembly process is convenient and the disassembly and assembly efficiency is high.

Please refer to Figures 1 to 4. In one embodiment, the locking mechanism 400 further includes an extension portion 450, which is disposed on the cover body 410 and has a third mounting hole 451. The mounting seat 100 has a second threaded hole 130. The second locking body 440 includes a second threaded component 441, which is passed through the third mounting hole 451 and is threadedly connected to the second threaded hole 130.

After the cover 410 is rotated to the position of closing the mounting opening 120, the user passes the second threaded component 441 through the third mounting hole 451 on the extension portion 450 of the cover 410 and screws it with the second threaded hole 130 on the mounting seat 100, thereby locking the cover 410 in the position of closing the mounting opening 120, so that the assembly portion 310 is clamped between the lock seat 200 and the pressing portion 420; such a configuration is low in cost and easy to operate, thereby improving the efficiency of disassembly and assembly.

Specifically, please refer to Figures 2 to 4. The plane where the extension portion 450 is located is perpendicular to the plane where the cover body 410 is located. When the cover body 410 is rotated to a position to close the mounting opening 120, the extension portion 450 is also correspondingly attached to the mounting seat 100, so that the second threaded component 441 passes through the third mounting hole 451 on the extension portion 450 and is threadedly connected to the second threaded hole 130 on the mounting frame 300.

Please refer to Figures 2 to 4. In one embodiment, the locking mechanism 400 further includes a connecting member 460, one side of which is rotatably disposed on a side of the mounting seat 100 where the mounting opening 120 is opened, and the other side of the connecting member 460 is connected to the cover 410.

The connecting member 460 has an extension 450 on one side thereof and is rotatably connected to the mounting seat 100. The other side of the connecting member 460 is connected to the cover 410. Thus, when the connecting member 460 rotates relative to the mounting seat 100, the extension 450 and the cover 410 also rotate together with the connecting member 460. The extension 450 rotates to a position close to the mounting seat 100, and the cover 410 rotates to a position close to the mounting seat 100. Then, the cover 410 is rotated to the position of closing the mounting opening 120, and the user passes the second threaded member 441 through the third mounting hole 451 on the extension portion 450 of the cover 410 and screws it with the second threaded hole 130 on the mounting frame 300, thereby locking the cover 410 at the position of closing the mounting opening 120, so that the mounting portion 310 is clamped between the lock seat 200 and the pressing portion 420.

The cover 410 is provided with a fourth mounting hole 411 . One end of the third threaded component 600 is passed through the fourth mounting hole 411 and is used to be screwed to the chassis 710 .

When the circuit board body 510 needs to be installed in the chassis 710, the assembly frame 300 is first installed on the mounting position 110 through the mounting opening 120, and the cover 410 is rotated to close the mounting opening 120, so that the assembly portion 310 is clamped between the lock seat 200 and the locking mechanism 400. The user rotates the third threaded component 600 to achieve threaded connection with the chassis 710, and then fixes the mounting seat 100 on the chassis 710 to achieve assembly of the circuit board body 510; in this way, when the circuit board body 510 on the chassis 710 needs to be disassembled, it only needs to be rotated by the third threaded component 600, and the process is convenient and the disassembly efficiency is high.

Furthermore, the first threaded component 431, the second threaded component 441 and the third threaded component 600 in the above embodiment all adopt thumb screws to reduce the difficulty of operation.
