FIG. 1 is a partial exploded view of a server device 10 of an embodiment of the present invention. FIG. 2 is an exploded view of a side-drawable expansion card assembly 500 of FIG. As shown in FIG. 1 and FIG. 2, in this embodiment, the server device 10 includes a chassis 100 and two side-drawable expansion card assemblies 500. The chassis 100 has a bottom plate 110 and two side walls 120. These side walls 120 are respectively vertically disposed on two opposite sides of the bottom plate 110, so that the bottom plate 110 and these side walls 120 together define the accommodating space 170. Each side wall 120 is provided with an opening 130 connected to the accommodating space 170, and is hinged to the case 100 through a side door 160, so that the side door 160 can be pivoted to cover or expose the corresponding opening 130. In addition, the case 100 further has a front end plate 140 and a rear end plate 150. The front end plate 140 and the rear end plate 150 are located at two opposite ends of the bottom plate 110 relative to each other, so that the bottom plate 110, these side walls 120, the front end plate 140 and the rear end plate 150 jointly define the accommodating space 170. However, the present invention is not limited to the front end plate 140 and the rear end plate 150 being non-essential components in the present invention.

These side-drawable expansion card assemblies 500 are relatively located in the accommodating space 170 and correspond to one of the openings 130 respectively. Each side-drawable expansion card assembly 500 includes a fixed frame 510, a plurality of (e.g., two) circuit side panels 600 and a plurality of (e.g., two) expansion card modules 700. The fixed frame 510 includes a main frame portion 520 and a plurality of (e.g., two) slide rail portions 570. The main frame portion 520 is fixedly located in the accommodating space 170 of the chassis 100. One side of the main frame portion 520 has a receiving groove 564, and the receiving groove 564 faces one of the openings 130. In other words, the receiving groove 564 is recessed on one side of the main frame portion 520 facing the opening 130. The rail sections 570 are arranged in sequence on the main frame 520 along a vertical direction (such as the Z axis), and further, the rail sections 570 are located on one side of the main frame 520 facing the receiving slot 564. The circuit side panels 600 are arranged in sequence on the main frame 520 along a vertical direction (such as the Z axis). Each circuit side panel 600 includes a wiring board 610 and at least one card slot 611. The wiring board 610 is fixed on the main frame 520, and the card slot 611 is located on one side of the wiring board 610 facing the opening 130. Each expansion card module 700 is removably disposed in the receiving slot 564 and is slidably engaged to one of the rail sections 570.

Therefore, when a user wants to install one of the expansion card modules 700, the user first opens the side door 160 of the chassis 100 to expose the opening 130 of the chassis 100, and then the user allows the expansion card module 700 to enter the receiving slot 564 of the fixed frame 510 from the opening 130 and engage with one of the slide rails 570. In this way, the expansion card module 700 can reach and be inserted into the corresponding card slot 611 along the slide rail 570, thereby completing the installation of the expansion card module 700. At this time, after the user has installed all the expansion card modules 700 of the side-drawable expansion card assembly 500 , these expansion card modules 700 overlap each other, and one of the main surfaces 742 of each expansion card module 700 faces the bottom board 110 .

On the contrary, when the user wants to remove the expansion card module 700, the user first opens the side door 160 of the chassis 100 to expose the opening 130, and then the user pulls the expansion card module 700 out of the card slot 611 of the circuit side panel 600, moves it out of the storage slot 564 of the fixed frame 510 along the slide rail portion 570, and completely detaches the chassis 100 from the opening 130 of the chassis 100.

More specifically, the main frame 520 includes a first side frame 530, a second side frame 540, a connecting side frame 550 and a bottom frame 560. The bottom frame 560 includes a plate portion 561 and a side plate portion 562. The plate portion 561 is fixedly placed flat on the bottom plate 110, and the side plate portion 562 extends upward from one edge of the plate portion 561 toward the vertical direction (such as the Z axis). The first side frame 530, the second side frame 540 and the connecting side frame 550 are all locked on the same surface of the plate portion 561, and extend upward from the plate portion 561 toward the vertical direction (such as the Z axis). One end of the connecting side frame 550 is locked to the second side frame 540, and the other end is locked to the side plate portion 562, and the first side frame 530 is locked to the side plate portion 562. Therefore, the first side frame 530, the second side frame 540, the connecting side frame 550 and the plate portion 561 of the bottom frame 560 together surround the receiving groove 564.

At this time, the long axis direction (such as the Y axis) of the first side frame 530 is parallel to the long axis direction (such as the Y axis) of the second side frame 540, and is orthogonal to the long axis direction (such as the X axis) of the bottom plate 110. The long axis direction (such as the X axis) of the connecting side frame 550 is parallel to the long axis direction (such as the X axis) of the bottom plate 110. The long axis direction (such as the X axis) of the plate body 561 is parallel to the long axis direction (such as the X axis) of the connecting side frame 550.

Each rail portion 570 includes at least one (e.g., two) first grooves 580 and at least one (e.g., two) second grooves 590. The first grooves 580 and the second grooves 590 face the receiving grooves 564 oppositely. For example, the circuit side plate 600 is locked to a surface of the connecting side frame 550 facing the receiving grooves 564, and the first grooves 580 are formed on a surface of the first side frame 530 facing the receiving grooves 564, and the second grooves 590 are formed on the second side frame 540 and face the first grooves 580.

FIG. 3 is an exploded view of the expansion card module of FIG. 2. As shown in FIG. 2 and FIG. 3, the expansion card module 700 includes a first support frame 710, a second support frame 720, and an expansion card component 740. The expansion card component 740 is fixed between the first support frame 710 and the second support frame 720. The first support frame 710 has a plurality of first sliding members 711 (such as sliding posts), that is, these first sliding members 711 are respectively fixed on the first support frame 710 and extend in a direction opposite to the expansion card component 740 (such as the X axis). These first sliding members 711 are slidably engaged with the first groove 580. The second support frame 720 has a plurality of second sliding members 721 (such as sliding nails), that is, the second sliding members 721 are fixed to the second support frame 720 and extend in a direction (such as the X axis) opposite to the expansion card element 740. The second sliding members 721 are slidably engaged with the second groove 590.

In addition, the expansion card component 740 includes an expansion card body 741 (such as a GPU card or a PCIe card) and a bracket 750. One side of the expansion card body 741 has a connection interface 743 (such as a gold finger connection portion), and the connection interface 743 is used to insert into the card slot 611 of the circuit side panel 600. The bracket 750 is fixed to one end of the expansion card body 741 and locked on the first supporting frame 710, and the second supporting frame 720 is located at one end of the expansion card body 741 opposite to the bracket 750. More specifically, the bracket 750 is L-shaped and is divided into a first sheet 751 and a second sheet 752. The first sheet 751 is locked to one end of the expansion card body 741 facing away from the second support frame 720 and inserted into the gap 551 of the connecting side frame 550. The second sheet 752 intersects (eg, is orthogonal to) the first sheet 751 and is locked to the first support frame 710.

More specifically, FIG. 4 is a partial enlarged view of the area M of FIG. 2. As shown in FIG. 4, the first side frame 530 has a first surface 531 and a second surface 532 adjacent to each other, the first surface 531 faces the receiving groove 564, and the second surface 532 faces one of the openings 130 (FIG. 1). The first groove 580 includes a straight line section 581, a break section 582, and a guide section 583. The straight line section 581 of the first groove 580 is located on the first surface 531, that is, the straight line section 581 of the first groove 580 is linearly arranged on the first surface 531, and the long axis direction (such as the Y axis) of the straight line section 581 is orthogonal to the long axis direction (such as the X axis) of the expansion card module 700. The guide section 583 is located on the first surface 531 and directly connects the straight section 581 and the breach section 582. The breach section 582 is located on the second surface 532, and the width W2 of the breach section 582 is greater than the width W1 of the straight section 581, and the length of the breach section 582 is less than the length of the straight section 581. Similarly, the second groove 590 has the same structure as the first groove 580, that is, the breach section 591 of the second groove 590 is opened on one side of the second side frame 540 facing the opening 130 (FIG. 1) of the chassis 100. Please refer to the first groove 580 (FIG. 2) mentioned above, and no further description is given.

Thus, when the user wants to install the expansion card module 700 (FIG. 1) into the chassis 100, the user opens the side door 160 of the chassis 100 to expose the breach section 582 of the first groove 580 and the breach section 591 of the second groove 590 of the side-drawable expansion card assembly 500; then, the user moves the first sliding member 711 and the second sliding member 721 (FIG. 2) on both sides of the expansion card module 700 from the breach section 582 and the breach section 591 into the first groove 580 and the second groove 590 respectively to continue the above-mentioned installation process.

Furthermore, more specifically, in this embodiment, the second supporting frame 720 includes a frame 722, a receiving groove 723 and a side notch 724. The frame 722 is connected to the second sliding members 721, and more specifically, the second sliding members 721 are fixed to a side of the frame 722 facing away from the expansion card component 740. The receiving groove 723 is located on the frame 722. The side notch 724 is formed on a side of the frame 722 facing the expansion card component 740, connected to the inner bottom surface 725 of the receiving groove 723, and connected to the receiving groove 723.

The expansion card module 700 further includes a positioning frame 730 and a plurality of (e.g., 2) locking elements 733. The positioning frame 730 includes a frame body 731 and a plurality of (e.g., 2) narrow through holes 732. The frame body 731 is fixed to one end of the expansion card body 741 facing away from the bracket 750, and is located in the receiving groove 723 and the side notch 724. More specifically, one side of the frame body 731 is fixed to the expansion card body 741, and the other side thereof extends from the side notch 724 into the receiving groove 723 and contacts the inner bottom surface 725 of the receiving groove 723. These narrow through holes 732 are arranged on the frame 731, and the long axis direction (such as X axis) of each narrow through hole 732 is parallel to the long axis direction (such as X axis) of the expansion card body 741. Each locking element 733 is located in one of the narrow through holes 732 and locks the frame 731 on the second supporting frame 720.

Thus, by fine-tuning the position of the locking element 733 in the narrow through hole 732, the user can adjust the length of the frame 731 extending out of the second supporting frame 720, thereby matching other expansion card bodies 741 of different lengths and locking the frame 731 thereon.

FIG. 5A and FIG. 5B are respectively operation diagrams of the booster 800 of FIG. 1. As shown in FIG. 2 and FIG. 5A, the fixed frame 510 further includes one or more protrusions 533, and these protrusions 533 are relatively located on the main frame 520. For example, these protrusions 533 are respectively located on a surface of the first side frame 530 facing the receiving slot 564 (such as the first surface 531, FIG. 4) and a surface of the second side frame 540 facing the receiving slot 564 (not shown in the figure). The expansion card module 700 further includes two boosters 800. These boosters 800 are respectively located on the first supporting frame 710 and the second supporting frame 720 (FIG. 2).

More specifically, as shown in FIG. 2 and FIG. 5A , each booster 800 includes a rotating frame 810 and a pivoting portion 820. The pivoting portion 820 is located on the rotating frame 810 and allows the rotating frame 810 to be rotatably connected to the expansion card module 700 (such as the first supporting frame 710 or the second supporting frame 720). The outer edge 811 of the rotating frame 810 has a recessed portion 830, and the recessed portion 830 accommodates the protrusion 533. The inner wall of the recessed portion 830 includes a bottom surface 831, an inclined surface 832 and a flat surface 833, and the bottom surface 831 is located between the inclined surface 832 and the flat surface 833, and the inclined surface 832 and the flat surface 833 are both connected to the outer edge 811 of the rotating frame 810.

Thus, as shown in FIG. 1 and FIG. 5A , when the user slides one of the expansion card modules 700 linearly in the chassis 100 to the corresponding card slot 611 but has not yet inserted it into the corresponding card slot 611, the user simultaneously rotates the rotating frames 810 on both sides of the expansion card module 700 in a clockwise direction C1, and the inner wall of the recessed portion 830 (such as the flat surface 833) squeezes the protrusion 533 of the fixed frame 510, so that the protrusion 533 generates a reaction force on the booster 800, so that the expansion card module 700 can be pushed into the corresponding card slot 611 along an insertion direction (see arrow A1). On the contrary, as shown in FIG. 5B , similarly, when the user rotates the rotating frames 810 on both sides of the expansion card module 700 in a counterclockwise direction C2, the inner wall of the recessed portion 830 (such as the inclined surface 832) squeezes the protrusion 533 of the fixed frame 510, so that the protrusion 533 generates a reaction force on the booster 800, so that the expansion card module 700 can be moved out of the corresponding card slot 611 along a withdrawal direction (see arrow A2). In this way, the boosters 800 on both sides of the expansion card module 700 can allow the user to insert the expansion card module 700 into the card slot 611 or remove it from the card slot 611 in a more labor-saving manner.

As shown in FIG. 2 and FIG. 5A, the fixing frame 510 further includes at least one first locking portion 534 (such as a screw hole). The first locking portion 534 is located on a surface (such as the second surface 532) of the first side frame 530 facing the opening 130. The booster 800 further includes a second locking portion 840 (such as a stud). The second locking portion 840 is located on the rotating frame 810 and is used to be releasably coupled to the first locking portion 534. Therefore, when the second locking portion 840 is locked to the first locking portion 534, the rotating frame 810 further covers the end of the slide rail portion 570 (i.e., the breakout section 582 of the first groove 580), thereby limiting the expansion card module 700 on the main frame portion 520 to prevent the expansion card module 700 from unexpectedly detaching from the main frame portion 520.

In addition, the server device 10 further includes a motherboard module 200, a power module 300 and a fan unit 400. The fan unit 400 is located in the accommodation space 170, and the fan unit 400 is fixed to these side walls 120. The long axis direction (such as the Y axis) of the fan unit 400 and the long axis direction (such as the X axis) of the bottom plate 110 are orthogonal to each other, and the fan unit 400 divides the accommodation space 170 into a front area 171 and a rear area (not shown in the figure). The front area 171 is located between the front end plate 140 and the fan unit 400, and the rear area is located between the rear end plate 150 and the fan unit 400. More specifically, in this embodiment, the fan unit 400 is locked to the bottom plate 110 and these side walls 120. The fan assembly 400 is configured with a plurality of fans 410 arranged in sequence to deliver the heat energy of the expansion card modules 700 to the back-end area.

The side-drawable expansion card assembly 500 is located in the front area 171. The power module 300 is located between the rear end plate 150 and the fan assembly 400 (i.e., the rear area). The motherboard module 200 is located in the rear area, electrically connected to the power module 300, and electrically connected to the expansion card module 700 through the corresponding circuit side plate 600. In addition, these side doors 160 are respectively hinged to the fan assembly 400, and the fixed frame 510 is fixedly connected to the fan assembly 400. For example, the side plate portion 562 of the bottom frame 560 is fixedly connected to the fan assembly 400, so that the air vent 563 on the fixed frame 510 is connected to the fan assembly 400. In addition, a partition channel 620 is separated between these side-drawable expansion card assemblies 500. The partition channel 620 is directly connected to the fan assembly 400 to provide heat dissipation air flow to the fan assembly 400 and to accommodate the wires (not shown) of these expansion card modules 700.

FIG. 6 is a cross-sectional view of a server device 11 according to an embodiment of the present invention. As shown in FIG. 6 , the expansion card modules 700A and 700B of the side-drawable expansion card assemblies 500 are arranged alternately.
