[0050] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0051] As described in the background art, the stable fixation of the PCIe card after it is plugged into the preset slot of the chassis is particularly important for its functional stability. In the related art, the fixing method of the PCIe card in the chassis includes: pressing the baffle of the PCIe card through a threaded connector or a card pressing mechanism to fix the baffle to the inner wall of the chassis, or fixing the baffle to a preset bracket in the chassis.

[0052] However, in the related art, the installation space of the PCIe card is relatively small, and it is inconvenient to apply force during manual disassembly, resulting in low efficiency in disassembly of the PCIe card.

[0053] The applicant has found that the above problem occurs because: as the application of PCIe cards becomes more and more widespread, especially when multiple PCIe cards are arranged side by side in a single chassis, the minimum distance between adjacent PCIe cards is only about 1.6mm. When an abnormality or failure among multiple PCIe cards needs to be removed, the force point for removing the single card is too small, making manual removal very difficult. The above application scenario is such as a graphics processing unit (GPU) in the form of a PCIe card.

[0054] In order to solve the above technical problems, the embodiment of the present application provides a PCIe card pressing device. Through the design of a pressing member with a first abutting portion, a second abutting portion and a force-applying portion, when the PCIe card is installed, after the PCIe card is inserted into a preset card slot in the chassis, the pressing member is rotated by means of the abutment cooperation between the PCIe card blocking piece and the first abutting portion, and the PCIe card is pressed into the card slot by the abutment of the second abutting portion and the PCIe card; the pressing member is further fixed to the chassis shell by a connecting member, thereby strengthening the stability of the pressing member in pressing the PCIe card, and improving the stability of the PCIe card. Not only that, after the connecting member and the card pressing member are released from the fixed state, the force-applying member is subjected to the steering force to drive the card pressing member to rotate, and then the PCIe card is pushed out of the card slot through the first abutting member. In other words, the rotating end of the card pressing member, the first abutting member and the second abutting member form a lever mechanism, which can realize the efficient lowering and lifting of the PCIe card baffle structure located in the card pressing space between the first abutting member and the second abutting member, thereby realizing the efficient installation and disassembly of the PCIe card. Compared with the related technology of directly manually inserting and removing the PCIe card from the chassis card slot, it is more labor-saving and convenient.

[0055] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0056] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0057] Reference Figures 1 to 7 The embodiment of the present application provides a card pressing device, including a connected card pressing member 100 and a connecting member 200, the card pressing member 100 is rotatably connected to the chassis shell 410, the card pressing member 100 has a first abutting portion, a second abutting portion and a force applying portion, the first abutting portion and the second abutting portion are arranged opposite to each other, and a card pressing space is formed between the two, so as to press the PCIe card blocking piece 500 located in the card pressing space, so that the PCIe card is pressed into the card slot in the chassis 400; the force applying portion is located on the side away from the rotating end of the card pressing member 100, and the force applying portion is configured to be driven by the steering force to drive the first abutting portion to rotate in a direction away from the card slot, so as to push the PCIe card out of the card slot; when the PCIe card is pressed into the card slot in the chassis 400, the connecting member 200 is used to fix the card pressing member 100 to the chassis shell 410.

[0058] In this way, by designing the card pressing member 100 with the first abutting portion, the second abutting portion and the force-applying portion, when the PCIe card is installed, after the PCIe card is inserted into the preset card slot in the chassis 400, the card pressing member 100 is rotated by means of the abutment cooperation between the PCIe card blocking piece 500 and the first abutting portion, and the PCIe card is pressed into the card slot by the abutment of the second abutting portion and the PCIe card; the card pressing member 100 is further fixed to the chassis shell 410 by the connecting member 200, thereby strengthening the card pressing stability of the card pressing member 100 for the PCIe card, and improving the installation convenience of the PCIe card, not only In this way, after the connecting member 200 and the pressing member 100 are released from the fixed state, the force-applying portion is subjected to the steering force to drive the pressing member 100 to rotate, and then the PCIe card is pushed out of the card slot through the first abutment portion. In other words, the rotating end of the pressing member 100, the first abutment portion and the second abutment portion form a lever mechanism, which can realize the efficient lowering and lifting of the PCIe card baffle 500 structure located in the card pressing space between the first abutment portion and the second abutment portion, thereby realizing efficient installation and removal of the PCIe card. Compared with the related technology of directly manually inserting and removing the PCIe card in the chassis card slot, it is more labor-saving and convenient.

[0059] On the basis of the above-mentioned embodiment, it can be improved that the pressing member 100 includes a pressing block 110, and the pressing block 110 is provided with a groove 111, such as a "U"-shaped groove 111, and the groove 111 is recessed toward the rotating end of the pressing member 100, and the groove 111 has a first side wall 1111 and a second side wall 1112 relative to each other, and a protrusion 1113 is provided on the inner side of the second side wall 1112, and the inner side of the first side wall 1111 and the protrusion 1113 respectively form a first abutting portion and a second abutting portion, which are respectively used to abut against the PCIe card block 500 located in the card pressing space between the inner side of the first side wall 1111 and the inner side of the second side wall 1112.

[0060] It is understood that a PCIe card is an expansion card connected to a computer motherboard to expand the functions and performance of the computer. A PCIe card is usually inserted into a PCI card slot on a motherboard and communicates with the motherboard via a PCIe bus; the PCIe card shield 500 is a metal plate on the back of a PCIe card, used to support and fix the position of the PCIe card in a computer chassis. The PCIe card shield 500 usually has an opening corresponding to a slot at the rear of a computer chassis, so that the PCIe card can be properly inserted into the chassis.

[0061] In some embodiments, the protrusion 1113 is perpendicular to the second side wall 1112, and the protrusion 1113 and the orthographic projection of the first side wall 1111 on the second side wall 1112 do not overlap. This arrangement prevents the protrusion 1113 serving as the second abutment portion and the first side wall 1111 serving as the first abutment portion from interfering with the PCIe card block 500 located therebetween during the process of rotating away from the card slot of the chassis 400, thereby affecting the removal of the PCIe card.

[0062] Furthermore, the bump 1113 is a rectangular bump 1113, and the bump 1113 has a rounded corner on one side facing the first side wall 1111, and the first side wall 1111 has a rounded end. In this way, the rounded design of the bump 1113 and the end of the first side wall 1111 reduces the contact wear between them and the PCIe card stop 500, which is beneficial to the structural protection of the card pressing part 100 and the PCIe card stop 500 and prolongs the service life of the two.

[0063] In more possible embodiments, the card pressing device also includes a rotating seat 300, which is fixedly connected to the chassis shell 410, and the pressing block 110 is hinged to the rotating seat 300. Exemplarily, the rotating seat 300 is threadedly fixed to the chassis shell 410, and the end of the pressing block 110 away from the opening of the groove 111 is hinged to the rotating seat 300. In this way, the rotating seat 300 is connected between the chassis shell 410 and the pressing block 110, which improves the rotational stability of the pressing block 110 and protects the mechanical structure of the pressing block 110 and the chassis shell 410.

[0064] In other possible embodiments, the rotating seat 300 includes a fixed bracket 310, connecting bolts and a rotating shaft 320. The fixed bracket 310 includes a base plate 311 and at least two side plates 312. The two side plates 312 are relatively arranged on both sides of the base plate 311 to form a U-shaped plate structure. Exemplarily, the side plates 312 and the base plate 311 can be an integrally formed structure or can be connected by split panels; the base plate 311 is provided with a mounting hole 3111, and the base plate 311 is fixed to the chassis shell 410 by connecting bolts passing through the mounting hole 3111; the side plate 312 is correspondingly provided with a through hole 3121, and the pressure block 110 is provided with a rotating hole, and the pressure block 110 is hinged to the fixed bracket 310 by the rotating shaft 320 passing through the through hole 3121 and the rotating hole; in another example, the connecting bolt is replaced by a rivet 230, and the base plate 311 is fixed to the chassis shell 410 by the rivet 230.

[0065] In some embodiments, the rotating seat 300 further includes a torsion spring 330, which is sleeved on the rotating shaft 320, the first end of the torsion spring 330 is connected to the rotating seat 300, and the second end of the torsion spring 330 is connected to the pressing block 110 to drive the pressing block 110 to rotate, wherein the elastic force direction of the torsion spring 330 is the counterclockwise rotation direction of the pressing block 110, that is, the direction in which the pressing block 110 is away from the chassis card slot, so that when the connecting member 200 and the pressing member 100 are unlocked, the torsion spring 330 is the pressing member. Component 100 provides a flipping force, and the auxiliary pressure block 110 rotates counterclockwise to facilitate the removal of the PCIe card. In another example, a first limiting hole 113 is opened on the side wall of the pressure block 110 away from the force-applying part, and the second end of the torsion spring 330 is penetrated through the first limiting hole 113 and is transmission-connected to the inner wall of the first limiting hole 113 of the pressure block 110, and the bottom plate 311 is provided with a second limiting hole 3112, and the first end of the torsion spring 330 is penetrated through the second limiting hole 3112 and is elastically connected to the bottom plate 311.

[0066] In more embodiments, a force plate 120 is connected to the pressure block 110 to form a force-applying portion, and the force plate 120 is tilted relative to the second side wall 1112; the angle between the force plate 120 and the outer side of the second side wall 1112 is an obtuse angle, and the connecting member 200 is a threaded connecting member 220, and the pressing member 100 is threadedly connected to the chassis shell 410 through the threaded connecting member 220. With such a design, when the threaded connecting member 220 is loosened, the staff can manually turn the force plate 120 to drive the pressing member 100 to rotate and release the pressing state. When the pressing member 100 rotates to about 70 degrees, the PCIe baffle can be removed, wherein the pressing member 100 is in the initial pressing position. , that is, the first side wall 1111 of the pressing block 110 is parallel to the notch of the card slot as a 0 degree reference; on the other hand, when the angle between the card pressing component 100 and the horizontal direction is 70 degrees, the personnel can also insert the PCIe card blocking piece 500 into the card pressing space between the first abutting portion and the second abutting portion of the card pressing component 100, and press down the PCIe card blocking piece 500 with both hands to make the card pressing component 100 rotate to a horizontal position by virtue of the abutting force between the PCIe card blocking piece 500 and the first abutting portion of the card pressing component 100, so that the second abutting portion presses the PCIe card blocking piece 500, or, while the personnel manually presses down the PCIe card blocking piece 500, manually pulls the force plate 120 to assist in driving the card pressing component 100 to rotate, thereby improving the card pressing efficiency.

[0067] As a possible implementation, the pressing block 110 has a limiting protrusion 112, which is arranged near the rotating end of the pressing block 110. The limiting protrusion 112 is used to abut against the outer wall of the chassis shell 410 to limit the rotation angle range of the pressing block 110. In this way, the setting of the limiting protrusion 112 can prevent the pressing block 110 from rotating too much when rotating counterclockwise, so that the pressing block 110 is in a pre-matching position that is not suitable for the PCIe card stopper 500 to extend into the card pressing space; when an elastic member such as a torsion spring 330 is provided at the rotating end of the pressing block 110, it is also easy to cause the torsion spring 330 to be overloaded, thereby shortening the component life of the elastic member.

[0068] In some other embodiments, the connecting member 200 includes a connecting plate 210 and a threaded connecting member 200, the connecting plate 210 is fixedly connected to the side of the second side wall 1112, and a threaded hole 211 is provided on the connecting plate 210. The pressing member 100 is fixed to the chassis shell 410 through the threaded connecting member 200, and the threaded connecting member 200 is sequentially passed through the threaded hole 211 and a preset connecting hole on the chassis shell 410. Exemplarily, the threaded connecting member 200 is a screw, and personnel can adjust the tightness of the connection between the pressing member 100 and the chassis shell 410 by adjusting the tightness of the threaded hole 211 passing through the connecting plate 210 and the connecting hole of the chassis shell 410.

[0069] In more embodiments, combined with Figure 7 A plurality of card pressing devices are assembled in a chassis 400 provided with a plurality of array-spaced PCIe cards to realize application for servers with larger PCIe card capacity.
