Description

Electronic devices and pressure-resistant modules

This case relates to an electronic device and a pressure-resistant module.

Generally speaking, the graphics card bracket is fixed to the case by screws. However, this method has the problem of alignment between the graphics card bracket and the case, requiring both hands to adjust the relative position and is difficult to lock. In addition, there is also the problem of screws falling off during the screw locking process. If the locking process is not done properly, it may also cause the threads to slip.

The present invention provides an electronic device, which is suitable for fixing a folding section of an expansion card bracket, including a chassis and a pressure module. The chassis includes an opening, a first buckling portion located above the opening, and a support platform located below the opening, and the folding section is suitable for being placed on the support platform. The pressure module is hinged on the support platform and rotates between a fixed position and an unfastened position. The pressure module includes a second buckling portion corresponding to the first buckling portion and a pressure piece. When the pressure module is located at the fixed position, the second buckling portion is buckled in the first buckling portion, and the pressure piece applies pressure to the folding section located on the support platform.

The present invention also provides a pressing module, which is suitable for being pivotally connected to a support platform of a chassis and is suitable for fixing a folding section of an expansion card bracket. The chassis includes a first buckling portion, and the pressing module includes a second buckling portion and a pressing member. When the pressing module is located at a fixed position, the second buckling portion is buckled with the first buckling portion, and the pressing member applies pressure to the folding section located on the support platform.

Based on the above, in the electronic device of the present case, the folding section of the expansion card bracket is suitable for being placed on the supporting platform of the chassis. The pressing module is hinged on the supporting platform of the chassis and rotates between a fixed position and an unlocked position. When the pressing module is located at the fixed position, the second snap-fitting portion of the pressing module is snap-fitted to the first snap-fitting portion of the chassis, and the pressing member of the pressing module applies pressure to the folding section located on the supporting platform, so that the expansion card bracket can be fixed to the chassis. In other words, the user only needs to flip the pressing module so that the second snap-fitting portion of the pressing module is snap-fitted to the first snap-fitting portion of the chassis, and the pressing member can press against the folding section of the expansion card bracket, without the need for additional tools, and the operation is quite convenient and simple.

Referring to FIGS. 1 to 3 , the electronic device 100 of this embodiment is suitable for fixing a folding section 12 of an expansion card bracket 10. The expansion card bracket 10 is fixed to an expansion card module 20. The expansion card module 20 includes, for example, an expansion card body 22 and a heat sink 24. The expansion card body 22 is, for example, a display card, and the heat sink 24 includes, for example, a combination of fins and a fan, but the types of the expansion card body 22 and the heat sink 24 are not limited thereto.

The electronic device 100 includes a chassis 110 and a pressing module 120. The chassis 110 can accommodate an expansion card module 20 (FIG. 1 and FIG. 2 only show a partial chassis 110), and the expansion card module 20 can be fixed to the chassis 110 through an expansion card bracket 10. As shown in FIG. 2, the chassis 110 includes an opening 112, a first buckle portion 114 located above the opening 112, and a support platform 116 located below the opening 112. The folding section 12 of the expansion card bracket 10 is suitable for being placed on the support platform 116.

The pressing module 120 is pivoted on the support platform 116 and rotates between a fixed position (FIG. 1) and a release position (FIG. 2). The pressing module 120 includes a second locking portion 126 corresponding to the first locking portion 114. When the pressing module 120 is located at the fixed position, the second locking portion 126 is locked on the first locking portion 114, and the pressing module 120 applies pressure to the folding section 12 of the expansion card bracket 10 located on the support platform 116, so that the expansion card bracket 10 can be fixed to the chassis 110, and the expansion card module 20 is also fixed to the chassis 110.

In other words, the user only needs to flip the pressing module 120 so that the second buckling portion 126 of the pressing module 120 is buckled on the first buckling portion 114 of the chassis 110, and the pressing module 120 can be pressed against the folded section 12 of the expansion card bracket 10 without the need for additional tools, which is very convenient and simple to operate.

Similarly, if the user wants to release the fixation of the expansion card module 20, the user only needs to release the second fastening portion 126 of the pressing module 120 from the first fastening portion 114 of the chassis 110 and flip the pressing module 120 to the unlocked position (FIG. 2). The pressing module 120 will no longer press against the folded section 12 of the expansion card bracket 10, and the expansion card module 20 can be removed from the chassis 110 together with the expansion card bracket 10.

It is worth mentioning that, as shown in FIG. 2 , the folding section 12 of the expansion card bracket 10 includes a first hole 14, and the pressing module 120 includes a positioning column 142. As shown in FIG. 3 , the support platform 116 includes a second hole 118 corresponding to the first hole 14. Therefore, when the pressing module 120 is located at a fixed position, the positioning column 142 penetrates the first hole 14 of the folding section 12 and the second hole 118 of the support platform 116 to further fix the relative position of the folding section 12 of the expansion card bracket 10 and the chassis 110.

Please refer to FIG. 4 to FIG. 6 . In this embodiment, the pressing module 120 includes a housing 122 pivotally mounted on the support platform 116 , a housing 125 fixed to the housing 122 , and a pressing member 130 located between the housings 122 and 125 .

The pressing member 130 includes a first section 132, two second sections 134 extending symmetrically from two ends of the first section 132 in a bent manner, and a fixing portion 136 connecting the two second sections 134. The fixing portion 136 is fixed to the housing 122 by, for example, a locking method. The other housing 125 is fixed to the housing 122 by, for example, a locking method, so that the pressing member 130 can be covered between the two housings 122, 125.

As shown in FIG. 6 , in this embodiment, the angle between each second section 134 and the first section 132 is less than 90 degrees. The shape of the pressing member 130 is, for example, close to a trapezoid or a triangle, but the shape of the pressing member 130 is not limited thereto. The above design allows the structure between the two second sections 134 and the first section 132 to be slightly deformed.

Since the thickness of the folding section 12 of different expansion card brackets 10 is slightly different, such a design allows the pressing member 130 to have a slightly deformed space when the folding section 12 is thicker, so that the pressing module 120 can still be well applied to the thicker folding section 12. In addition, the design of the two symmetrical second sections 134 can also provide uniform downward pressure.

In addition, the housing 122 includes a limiting portion 124 located beside the first section 132 and between the two second sections 134 to limit the upward movement of the first section 132 to prevent the pressing member 130 from being over-deformed.

In this embodiment, the material of the pressure member 130 can be plastic, and has a certain structural strength to provide a downward pressure to the folding section 12. In addition, the pressure module 120 includes an exposed flexible friction member 150, which is suitable for contacting the folding section 12. The material of the flexible friction member 150 can be rubber, which can be slightly deformed to contact or/and fit the folding section 12 to provide the folding section 12 with uniform friction.

The pressure module 120 further includes a reinforcing member 140, which is located between the pressure member 130 and the flexible friction member 150. The reinforcing member 140 is made of, for example, metal, to provide rigid strength and to even out the downward pressure of the pressure member 130. A positioning column 142 is formed on the reinforcing member 140, and the positioning column 142 passes through the flexible friction member 150. The positioning column 142 with greater structural strength can further provide a better positioning effect.

Therefore, in this embodiment, the pressing module 120 provides a uniform and stable downward pressure to the folding section 12 of the expansion card bracket 10 through the pressing member 130, the reinforcing member 140 and the flexible friction member 150, so as to well fix the folding section 12 of the expansion card bracket 10 to the supporting platform 116 of the chassis 110.

In addition, the pressing module 120 has a structure that is slightly deformable due to the design of the pressing member 130 having two symmetrical second sections 134 extending from both ends of the first section 132 in a bent manner, thereby providing a first level of slight deformation possibility. Furthermore, the pressing module 120 can provide a second level of slight deformation possibility due to the compressible material of the flexible friction member 150, thereby ensuring that the pressing module 120 can be used to press against the folded sections 12 of the expansion card bracket 10 of different thicknesses.

In summary, in the electronic device of the present invention, the folding section of the expansion card bracket is suitable for being placed on the supporting platform of the chassis. The pressing module is hinged on the supporting platform of the chassis and rotates between a fixed position and an unlocked position. When the pressing module is located at the fixed position, the second snap-fitting portion of the pressing module is snap-fitted to the first snap-fitting portion of the chassis, and the pressing member of the pressing module applies pressure to the folding section located on the supporting platform, so that the expansion card bracket can be fixed to the chassis. In other words, the user only needs to flip the pressing module so that the second snap-fitting portion of the pressing module is snap-fitted to the first snap-fitting portion of the chassis, and the pressing member can press against the folding section of the expansion card bracket, without the need for additional tools, and the operation is quite convenient and simple.
