[0077] The following will disclose multiple embodiments of the utility model with the accompanying drawings. For the purpose of clear description, many practical details will be described together in the following description. However, those skilled in the art should understand that in some embodiments of the utility model, these practical details are not necessary and should not be used to limit the utility model. In addition, in order to simplify the drawings, some conventional structures and components will be shown in a simple schematic manner in the drawings. In addition, for the convenience of readers, the sizes of the components in the drawings are not shown according to the actual proportion.

[0078] Figure 1 It is a three-dimensional diagram of an electronic device 10 according to an embodiment of the present invention. Figure 2 for Figure 1 FIG. 1 is a diagram of the operation of using the electronic device 10. In this embodiment, Figure 1 and Figure 2As shown, the electronic device 10 includes an expansion card module 100 and a circuit board device 200. The expansion card module 100 is vertically arranged on the circuit board device 200 and is electrically connected to the circuit board device 200. The circuit board device 200 includes a circuit board module 210 and a disassembly aid component 300. The circuit board module 210 includes a circuit board body 211 and a slot component 220, and the slot component 220 is fixed to the circuit board body 211. More specifically, the front side 211T of the circuit board body 211 has a circuit pattern 212, and the slot component 220 is fixed to the front side 211T of the circuit board body 211 and is electrically connected to the circuit pattern 212 of the circuit board body 211. The slot component 220 is in the shape of an elongated strip, that is, the long axis direction (such as the Y axis) of the slot component 220 and the short axis direction (such as the Y axis) of the circuit board body 211 are parallel to each other.

[0079] The expansion card module 100 includes a narrow and long card body 110, a connection interface 120 and a buckle portion 130. The connection interface 120 and the buckle portion 130 are located together on the long side 111 of the narrow and long card body 110, and the connection interface 120 is removably inserted into the slot component 220. More specifically, the front surface 211T of the circuit board body 211, the slot component 220 and the long side 111 of the narrow and long card body 110 together define a narrow and long gap G. The long axis direction (such as the Y axis) of the narrow and long gap G is parallel to the long axis direction (such as the Y axis) of the slot component 220, and the buckle portion 130 of the narrow and long card body 110 extends from the long side 111 of the narrow and long card body 110 into the narrow and long gap G. More specifically, the connection interface 120 (e.g., gold finger) extends downward from the long side 111 of the narrow card body 110 and is electrically connected to the circuit pattern 212 of the circuit board body 211 through the slot element 220. The buckle portion 130 is L-shaped, one side of which is adjacent to the connection interface 120, and the other side of which forms a fastening notch 131 with the long side 111 of the narrow card body 110.

[0080] In this embodiment, the circuit board body 211 is, for example, a motherboard; the slot element 220 is, for example, a PCIe slot; and the expansion card module 100 is, for example, a display card device, however, the present invention is not limited thereto.

[0081] The disassembly assisting assembly 300 is disposed on the circuit board module 210 and is located in the narrow gap G. The disassembly assisting assembly 300 has a rotation axis (such as the Y axis), and the rotation axis (such as the Y axis) of the disassembly assisting assembly 300 is parallel to the long axis direction (such as the Y axis) of the slot element 220 and the long axis direction (such as the Y axis) of the narrow gap G. In this way, the disassembly assisting assembly 300 rotates unidirectionally around the rotation axis (such as the Y axis) to be fixed to the buckling portion 130, or rotates in the opposite direction to be separated from the buckling portion 130.

[0082] It should be understood that the narrow gap G formed between the circuit board body 211, the slot element 220 and the narrow card body 110 is quite limited and belongs to the idle space on the circuit board device 200. Therefore, the disassembly aid component 300 is configured in the narrow gap G without occupying the space configuration of the circuit board module 210, which helps to improve the flexibility of the space configuration in the electronic device 10.

[0083] Figure 3A For along Figure 1 A partial cross-sectional view of line segment AA. Figure 3B for Figure 3A Operation diagram of the use. Figure 2 and Figure 3A As shown, in this embodiment, the disassembly aid assembly 300 includes a housing 310, a rotating arm 380 and a hook 390. The housing 310 is fixed to the circuit board body 211 and is partially located in the narrow gap G ( Figure 1 The rotating arm 380 is rotatably located in the housing 310 and is used to rotate around the long axis direction (such as the Y axis) of the narrow gap G. The hook member 390 is fixed to one end of the rotating arm 380 and can be hooked onto the buckling portion 130 as the rotating arm 380 rotates unidirectionally ( Figure 3A ) or disengages from the locking portion 130 as the rotating arm 380 rotates in the reverse direction ( Figure 3B ).

[0084] Furthermore, if Figure 3A As shown, in this embodiment, the hook member 390 includes a fixing portion 391, a hook head 393 and a hook body 394. The hook body 394 is respectively connected to the fixing portion 391 and the hook head 393. The fixing portion 391 is fixed to one end of the rotating arm 380 extending out of the shell 310. The fixing portion 391, the hook body 394 and the hook head 393 jointly define a hook groove 395. The hook groove 395 is used to accommodate the buckling portion 130. The fixing portion 391 also has an upper top 392 on the side facing the hook groove 395, that is, the upper top 392 extends toward the hook groove 395. Therefore, as shown in FIG. Figure 3B As shown, when the hook member 390 rotates and disengages from the locking portion 130, that is, the locking portion 130 is disengaged from the hook groove 395, the limit imposed by the hook member 390 on the locking portion 130 is released, and the user can directly pull the expansion card module 100 upward out of the slot component 220, or the hook member 390 is designed to push the locking portion 130 through the upper top 392, so that the expansion card module 100 is pushed upward out of the slot component 220, and thus away from the circuit board module 210.

[0085] Furthermore, Figure 4 for Figure 1 The exploded view of the disassembly aid assembly 300 is shown. Figure 2 and Figure 4As shown, in this embodiment, the rotating arm 380 includes a handle 381, a linear shaft 382 and a bent portion 383. The handle 381 is located outside the narrow gap G and extends from the first long hole 303 on the top surface of the housing 310, so that the user can easily operate the rotation of the rotating arm 380. The linear shaft 382 is parallel to the long axis direction (such as the Y axis) of the narrow gap G. One end of the linear shaft 382 extends from the second long hole 304 on the side of the housing 310 facing the slot element 220 and is fixed to the hook 390. The bent portion 383 connects the linear shaft 382 and the handle 381 respectively, and the height of the bent portion 383 is greater than the height of the linear shaft 382, ​​but is not limited thereto. The height of the bent portion 383 can also be equal to or less than the height of the linear shaft 382.

[0086] So, like Figure 1 and Figure 4 As shown, when a user moves the handle 381 in the clockwise direction C2, the linked bending portion 383, the linear shaft 382 and the hook member 390 rotate synchronously, and the hook member 390 is thus away from the fastening notch 131 of the fastening portion 130, thereby completing the step of unlocking the expansion card module 100 ( Figure 3B ). On the contrary, Figure 2 and Figure 4 As shown, when the user turns the handle 381 in the counterclockwise direction C1, the linked bending portion 383, the linear shaft 382 and the hook member 390 rotate synchronously, and the hook member 390 moves into the fastening notch 131 of the fastening portion 130, thereby completing the step of locking the expansion card module 100 ( Figure 3A ). However, the present invention is not limited thereto, and the bending portion 383 of the rotating arm 380 may be omitted in other requirements or limitations.

[0087] More specifically, in this embodiment, the housing 310 includes an outer cover 350 and a bottom cover 370. The outer cover 350 and the bottom cover 370 can be covered with each other through the studs B, thereby completing the housing 310, so that most of the rotating arm 380 can be accommodated in the housing 310.

[0088] Furthermore, the housing 310 is L-shaped and is divided into a first portion 301 and a second portion 302, and the first portion 301 and the second portion 302 are orthogonal to each other. The first portion 301 extends linearly in the narrow gap G, and the long axis direction of the first portion 301 is parallel to the long axis direction of the narrow gap G (such as the Y axis). The second portion 302 extends horizontally out of the narrow gap G in an extension direction orthogonal to the Y axis (such as the X axis). However, the present invention is not limited to the detailed structure and appearance of the housing 310.

[0089] Figure 5 for Figure 4The disassembly aid component 300 is viewed from another perspective and a partial enlarged view of a specific area thereof. Figure 5 As shown, the housing 310 further includes a plurality of first ribs 320 and at least one second rib 330. These first ribs 320 are arranged transversely in the housing 310 (e.g., the inner top surface 350T of the outer cover 350) at intervals along the long axis direction (e.g., the Y axis). Each first rib 320 has a first slot 321, and these first slots 321 are coaxially aligned along the long axis direction (e.g., the Y axis). Therefore, the linear shaft 382 of the rotating arm 380 can be rotatably placed in these first slots 321. The second rib 330 is located in the housing 310 (e.g., the inner top surface 350T of the outer cover 350). The second rib 330 has a second slot 331, and the opening direction of the second slot 331 (e.g., the X axis) is orthogonal to the opening direction of the first slot 321 (e.g., the Y axis). Therefore, the bending portion 383 of the rotating arm 380 can be rotatably placed in the second slot 331.

[0090] Furthermore, Fig. 6A and Figure 6B They are cross-sectional views of the rotating arm 380 and the elastic element 400 of the disassembly aid assembly 300 in different operating states. Figure 4 and Fig. 6A As shown, the disassembly aid assembly 300 further includes an elastic element 400. The elastic element 400 is located in the housing 310 and abuts against the housing 310 and the rotating arm 380 respectively to return the rotating arm 380 to its original position, for example, to rotate the hook 390 into the fastening notch 131 of the fastening portion 130 ( Figure 3A For example, one end of the elastic element 400 abuts against the bent portion 383 to push the hook member 390 back into the fastening notch 131 of the fastening portion 130 .

[0091] Specifically, in this embodiment, the housing 310 (e.g., the inner side 350R of the outer cover 350) further has a fixing groove 360. The elastic element 400 includes a body portion 410, a wave portion 420, and a connecting portion 430. The body portion 410 is removably inserted into the fixing groove 360 ​​of the housing 310 (e.g., the outer cover 350). The wave portion 420 partially abuts against the bent portion 383, and the connecting portion 430 connects the body portion 410 and the wave portion 420 respectively. The connecting portion 430 is, for example, U-shaped, however, the present invention is not limited to the appearance of the connecting portion 430.

[0092] So, like Figure 6B As shown in FIG. 1 , when the user turns the handle 381 in the clockwise direction C2 to unlock the expansion card module 100, the bent portion 383 presses down and deforms the elastic element 400 along with the rotating arm 380. At this time, the deformed elastic element 400 stores a restoring elastic force; conversely, Fig. 6AAs shown, when the user turns the handle 381 in the counterclockwise direction C1 to lock the expansion card module 100, the restoring elastic force of the elastic element 400 can return the rotating arm 380 to its original position.

[0093] In one embodiment of the present invention, Figure 5 and Fig. 6A As shown, the housing 310 further includes two stopper protrusions 340, which are respectively protruded from two opposite inner walls 332 of the second rib 330 facing the second slot 331 and have the same height as each other. However, the present invention is not limited thereto, and other embodiments may also only have a single stopper protrusion.

[0094] Thus, when the user rotates the rotating arm 380 in the clockwise direction C2 so that the bent portion 383 passes downward through the stop convex points 340, the stop convex points 340 can resist the restoring elastic force of the elastic element 400 on the rotating arm 380, thereby stopping the restoration of the bent portion 383. Thus, when the user turns the handle 381 to unlock the expansion card module 100, since the bent portion 383 is pressed downward (along the Z axis) and passes between the stop convex points 340, the stop convex points 340 can stop the bent portion 383 from returning upward (along the Z axis), thereby resisting the restoring elastic force of the elastic element 400, and temporarily stopping the rotating arm 380, so that the user can free both hands to completely remove the expansion card module 100 from the slot element 220.

[0095] Thus, through the above structure, the electronic device of the utility model helps the user to quickly and conveniently install or remove the expansion card, thereby improving the user's usage experience.

[0096] Finally, the above disclosed embodiments are not intended to limit the present invention. Any person skilled in the art can make various changes and modifications without departing from the concept and scope of the present invention, and all of them can be protected by the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
