Detailed Description

As described in the background art, in the related art, the implementation manner of the PCIE clamping and pressing fixing structure includes a spring unlocking type pressing structure and an elastic bump type pressing structure, which has the defects of more parts required for implementing the structure, complex connection and matching manners of parts, need to preprocess chassis parts, and the like, and has the problems of higher product manufacturing and using costs, worse user experience, and the like.

The inventors have found that the above problems occur mainly due to: on the one hand, combine the spring unlocking formula press-clamping structure that fig. 1 and 2 show, it includes support piece and press-clamping piece that rivets in quick-witted case rear window 2 through first peg 4, be equipped with rotatory shaft hole on the press-clamping piece, rotation axis 5 hole is used for cooperating rotation axis 5 on the support piece and makes press-clamping piece and support piece fixed connection, rotation axis 5 axial cover is equipped with spring 3, when rotation axis 5 screw in rotatory shaft hole, drive spring 3 along rotation axis 5 axial compression deformation to carry out spacingly through first peg 4 of riveting on the quick-witted case rear window 2. After unlocking, the spring unlocking type card pressing structure is opened by turning over the card pressing piece.

However, the design of the spring unlocking type press card structure is complex, the structure is realized by a plurality of parts and complex matching relations among the parts, and the raw material manufacturing and processing cost is high; in addition, the spring unlocking type card pressing structure also limits the application environment of the card pressing structure per se due to the close matching relation of all the components, and the practicability is low.

On the other hand, the metal elastic card pressing structure is shown in fig. 2 and 3 as an example, and the metal elastic card pressing structure comprises a metal card pressing piece 7, wherein the metal card pressing piece 7 is rotatably connected to the chassis rear window 2 through the matching of a metal pin and a shaft hole arranged on the chassis rear window 2, and a clamping bump 6 is arranged on the metal card pressing piece 7 and is used for rotatably connecting the metal card pressing piece 7 to a hole correspondingly formed in the rear window of the chassis rear window 2 so as to realize card pressing fixation of PCIE cards.

However, as the metal elastic pressing card structure is required to be matched with the clamping convex points 6 on two sides to manufacture and process corresponding slotted holes, as the number of PCIE cards increases, the gaps among the PCIE cards can be continuously reduced, so that the processing space of the slotted holes can not be continuously compressed, even the processing and the manufacturing can not be realized, the structural function of the metal elastic pressing card can not be smoothly realized, and meanwhile, the mounting of the PCIE cards can be hindered under the condition; in addition, the processing height of the clamping bump 6 lacks flexibility, and too low or too high processing height can negatively affect the unlocking hand feeling of the user, so that the use experience of the user is poor.

Aiming at the technical problems, the embodiment of the utility model provides a card pressing assembly, which can be pushed and pulled by a user through a matching structure of a card pressing mechanism with a plurality of channels and a fixing assembly to realize the locking and unlocking of a PCIE card pressing card, wherein for the user, a push-pull type, namely an opening and closing mode of linear displacement, ensures that the PCIE card is locked or unlocked without secondary action of structural resetting of the card pressing assembly, further improves the convenience of mounting and dismounting the PCIE card, has simpler and more convenient overall operation compared with the prior art, can be suitable for pressing cards of PCIE cards in various layout assembly modes, and has higher practicability; meanwhile, the occupied space of the clamping mechanism, the fixing component and the supporting seat after being assembled in the case is small, and particularly in a locking state, the whole product structure can be completely hidden in the case, so that the space utilization rate of the case is comprehensively improved.

In order to make the above objects, features and advantages of the embodiments of the present utility model more comprehensible, the technical solutions of the embodiments of the present utility model will be described clearly and completely with reference to the accompanying drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 4, an embodiment of the present utility model provides a card pressing assembly, which includes a supporting seat 10, a card pressing mechanism 20 and a fixing assembly 30, wherein a plurality of channels are provided on the card pressing mechanism 20, and the fixing assembly 30 passes through the plurality of channels and is fixed on the supporting seat 10.

In this way, the cooperation structure of the card pressing mechanism 20 with a plurality of channels and the fixing assembly 30 can be pushed and pulled by a user to realize the locking and unlocking of the PCIE card, wherein, for the user, the push-pull type, namely the opening and closing mode of linear displacement, enables the PCIE card to be locked or unlocked without the secondary action of resetting the card pressing assembly, thus further improving the convenience of installing and dismantling the PCIE card, and the overall operation is simpler and more convenient than the prior art, and can be suitable for the pressing of PCIE cards in various layout and assembly modes, and the practicability is higher; meanwhile, the space occupied by the card pressing mechanism 20, the fixing assembly 30 and the supporting seat 10 after being assembled in the case is small, and particularly in a locking state, the whole product structure can be completely hidden in the case, so that the space utilization rate of the case is comprehensively improved.

It should be noted that, the supporting seat 10 fixed on the rear window 2 of the chassis provides a supporting function for the card pressing mechanism 20, and the card pressing mechanism 20 is limited by the fixing component 30 fixed on the supporting seat 10, so that good overall stability of the card pressing mechanism 20 and clamping accuracy and fixing reliability of the PCIE card are ensured.

Further, the press-clamping mechanism 20 includes a bottom plate 21 and side walls 22 connected to each other, the plurality of channels includes a first channel 25 disposed on the bottom plate 21 and a second channel 26 disposed opposite to the two side walls 22, the fixing assembly 30 includes a first fixing member passing through the first channel 25 and a second fixing member passing through the second channel 26, as shown in fig. 5, the first channel 25 is a hole penetrating through the middle of the bottom plate 21, the first fixing member is a rivet riveted to the supporting seat 10, for example, the rivet may be a hanging nail 31, the hanging nail 31 penetrates the hole, and the press-clamping mechanism 20 may linearly translate along the length direction of the hole relative to the supporting seat 10, so as to implement that the press-clamping mechanism 20 is pushed into or pulled out of the chassis by an external force to complete locking or unlocking.
