The disclosure is related to a circuit board, and particularly to a circuit board having a release structure.
Generally speaking, to release a graphics card inserted in a card slot on a motherboard, a graphics card release structure next to a turning card slot is used to release and lift the graphics card. However, with the improvement of the specifications of related equipment around the motherboard (for example: the increase in the dimensions of the CPU tower radiator, the larger size of the heat dissipation elements, the increase in the number of exterior decorative members, etc.), after the graphics card is inserted into the card slot, most of the area of the graphics card release structure is blocked, making it difficult for users to press. At present, users often use other tools to press the graphics card release structure. However, doing so often causes damage to the graphics card release structure, and the graphics card release structure is not easy to press, and the elements on the motherboard may even be damaged, resulting in the inability to readily release/replace the graphics card, and resulting in poor user experience.
The disclosure provides a circuit board including a board body, a card slot, a release structure, and a transmission mechanism. The card slot is disposed on the board body and adapted for inserting an expansion card. The release structure is rotatably disposed beside the card slot. The transmission mechanism includes a contact part and a stressed part that are linked to each other, wherein the contact part is connected to the release structure. When the stressed part receives an external force, the contact part is moved correspondingly, so that the release structure is rotated relative to the card slot, thereby releasing the expansion card.
The circuit board of the disclosure uses a transmission mechanism to rotate the release structure relative to the card slot, thereby releasing the expansion card. In this way, even if the release structure is blocked by structures such as the expansion card and heat dissipation fins, users may still readily rotate the release structure.
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
In the present embodiment, the circuit board 100 includes a board body 110, a card slot 115, a release structure 120, and a transmission mechanism 130. The card slot 115 is disposed on the board body 110 and may be used for inserting the expansion card 10. The card slot 115 is, for example, a PCI-E slot, but the type of the card slot 115 is not limited thereto.
The release structure 120 is rotatably disposed beside the card slot 115, and turning the release structure 120 may push up and release the expansion card 10 inserted into the card slot 115. It may be seen from
In an embodiment, the transmission mechanism 130 is linked to the release structure 120, and the circuit board 100 may rotate the release structure 120 via the transmission mechanism 130 as shown in
The transmission mechanism 130 includes a contact part 133 and a stressed part 134 linked to each other. The contact part 133 is connected to the release structure 120. Specifically, the contact part 133 is in contact with the release structure 120 so that the release structure 120 is linked to the contact part 133. The contact part 133 is linked to the stressed part 134.
In an embodiment, the transmission mechanism 130 includes a pull wire 131, and an end of the pull wire 131 is connected to the contact part 133. The contact part 133 is, for example, a hook, and the contact part 133 is disposed at an end of the pull wire 131 and hooked on the column body 122 of the release structure 120. The stressed part 134 includes a pull ring 135 and is disposed at another end of the pull wire 131.
In an embodiment, the contact part 133 is linked to the stressed part 134 via the pull wire 131. Of course, in other embodiments, the linking manner of the contact part 133 and the stressed part 134 is not limited thereto.
As may be seen from

In other embodiments, the transmission mechanism 130 may also be partially located under the expansion card 10 and the heat dissipation fins 12, the stressed part 134 is located at a position not blocked by the expansion card 10 and the heat dissipation fins 12, and the user may still readily access the transmission mechanism 130. The position of the transmission mechanism 130 is not limited thereto.
In addition, since the contact part 133 is directly connected to the release structure 120, the stressed part 134 of the transmission mechanism 130 is farther away from the release structure 120 than the contact part 133. In other words, the distance between the stressed part 134 and the release structure 120 is greater than the distance between the contact part 133 and the release structure 120. The stressed part 134 may be disposed at a place more convenient for the user to operate, and is disposed corresponding to the space configuration on the board body 110.
In the present embodiment, the user only needs to pull the stressed part 134 (the pull ring 135) to pull the pull wire 131, so that the contact part 133 drives the column body 122 of the release structure 120 to be rotated relative to the rotating shaft 121 to release the expansion card 10.
Moreover, when the user wants to insert the expansion card 10 into the card slot 115, the expansion card 10 presses the pushing part 124 of the release structure 120 to turn the release structure 120 back to the original position (
In the present embodiment, the pulling direction of the pull ring 135 is upward as an example, and is not limited thereto. In an embodiment, the stressed part 134 (the pull ring 135) may also be connected to a driving module (for example, a motor). That is, a motor may be used to pull the release structure 120 to release the graphics card.

When the button 136 is pressed down and moved to the position of
In an embodiment, the fixing part 146 has a hollow rectangular shape or elliptical shape, so that the manufacturer may finely adjust the position of the fixing part 146 relative to the screw hole of the base body 140a. For example, if the pull wire 131 is too loose, then the pull wire 131 may not be well linked when the button 136 is pressed down. At this point, the manufacturer may slightly move the fixing part 146 in a direction away from the button 136 (for example, the lower right of
Therefore, the fixing part 146 has a hollow rectangular shape or elliptical shape design, so that when the fixing part 146 is slightly moved in a direction away from the button 136 or close to the button 136, the locking member 148 may still pass through the through hole 147 of the fixing part 146, and then be locked to the base body 140a. In other words, the elongated through hole 147 may be used to provide a space for the fixing part 146 to be finely adjusted relative to the base body 140a.

The moving member 132 is located between a contact part 133b and a stressed part 134b. The contact part 133b is abutted against an abutting part 125 of the release structure 120. The stressed part 134b is, for example, a handle 137. The handle 137 may be close to an edge 116 of the board body 110 to facilitate the operation of the user.
In the present embodiment, the user only needs to pull the handle 137 to drive the moving member 132. As a result, the contact part 133b pulls the abutting part 125 of the release structure 120, so that the release structure 120 is rotated to release the expansion card 10.
Moreover, in the present embodiment, the moving member 132 includes a guide groove 138, and the plate body 110 includes a guide column 114 penetrating the guide groove 138. The moving member 132 may be moved on the plate body 110 in a specific direction via the cooperation of the guide column 114 and the guide groove 138.
Moreover, in the present embodiment, the circuit board 100 further includes a driving module 150. The driving module 150 is connected to the stressed part 134b of the transmission mechanism 130, and is capable of electrically moving the stressed part 134b.
The driving module 150 is, for example, a motor, a hydraulic cylinder, a pneumatic cylinder, an electromagnet, etc., and the type of the driving module 150 is not limited thereto. In addition, the driving module 150 may be disposed outside the board body 110 or on the board body 110, and the position of the driving module 150 may be adjusted according to the space configuration, and is not limited to the figures.
Based on the above, the circuit board of the disclosure uses a transmission mechanism to rotate the release structure relative to the card slot, thereby releasing the expansion card. In this way, even if the release structure is blocked by a structure such as the expansion card and the heat dissipation fins, the user may still readily rotate the release structure.
