Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of computer devices, and particularly to a card pressing mechanism, a chassis, and a server. Background Art

[0002] Currently, in existing PC (Personal Computer) chassis or servers, the screw-free fixing method for PCIE (Peripheral Component Interconnect Express) cards mainly uses a stop structure on the elastic arm of the pressure strip for fixing. The elastic arm of the pressure strip can be rotatably arranged on the chassis along the axis in the thickness direction of the PCIE card. By flipping the elastic arm of the pressure strip, the stop lug of the elastic arm of the pressure strip is snapped into the corresponding hole of the rear window iron part of the chassis, and the pressure card fixing is realized by relying on the clamping lug on the elastic arm of the pressure strip and the hole on the rear window iron part. There are many drawbacks in this fixing structure of the PCIE card. For example, the clamping lug is easily worn after being opened and closed multiple times, which will cause the loss of the stop effect; if the fitting clearance error between the clamping lug and the hole is large, the pressing force on the PCIE card will be insufficient, and the entire elastic arm of the pressure strip is prone to shake up and down; since the elastic arm of the pressure strip rotates along the axis in the thickness direction of the PCIE card, the completely flipped and opened elastic arm of the pressure strip will occupy the space of the PCIE card in the plugging and unplugging direction, thus affecting the plugging and unplugging of the PCIE card. Summary of the Invention

[0003] The purpose of the embodiments of the present invention is to provide a card pressing mechanism, a chassis, and a server, aiming to solve the problem that there are many drawbacks in the existing fixing structure of the PCIE card.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0045] The present invention provides a pressing and clamping mechanism, which can be applied to a chassis or a server. Hereinafter, an example of applying the pressing and clamping mechanism to a chassis will be used for illustration. Figures 1 to 11 A preferred embodiment of the pressing and clamping mechanism provided by the present invention is shown.

[0046] Please refer to Figures 1 to 3, in this embodiment, the card pressing mechanism 100 includes a mounting bracket 1, a card pressing base 2, and a sliding member 3. The mounting bracket 1 forms a mounting area 11, and an insertion opening 111 for inserting an external card 200 is provided in the mounting area 11. The mounting bracket 1 includes a first connecting portion 12 and a second connecting portion 13 respectively disposed on both sides of the mounting area 11. One end of the card pressing base 2 is rotatably connected to the first connecting portion 12. When the card pressing base 2 is in the closed position, the card pressing base 2 closes the insertion opening 111. The sliding member 3 is slidably connected to the end of the card pressing base 2 away from the first connecting portion 12 along the extending direction of the card pressing base 2. Wherein, a buckling portion 31 and a holding portion 131 are respectively provided at the end of the sliding member 3 away from the first connecting portion 12 and the second connecting portion 13. When the card pressing base 2 is in the closed position and the sliding member 3 is in the first position, the buckling portion 31 is buckled with the holding portion 131 to limit the rotation of the card pressing base 2. When the sliding member 3 is in the second position, the buckling portion 31 is separated from the holding portion 131.

[0047] Specifically, hereinafter, the orientation of the insertion opening 111 is defined as upward, the first connecting portion 12 is located on the right side of the mounting area 11, the second connecting portion 13 is located on the left side of the mounting area 11, the direction of the rotation axis of the card pressing base 2 is the front-back direction, the ends of the card pressing base 2 and the sliding member 3 close to the first connecting portion 12 are respectively the proximal end of the card pressing base 2 and the proximal end of the sliding member 3, and the ends of the card pressing base 2 and the sliding member 3 away from the first connecting portion 12 are respectively the distal end of the card pressing base 2 and the distal end of the sliding member 3.

[0048] A card seat 14 matching the external card 200 is provided on the mounting bracket 1 for realizing the electrical connection between the chassis and the external card 200. Wherein, the external card 200 can be a PCIE card or other types of external cards, and no excessive limitation is made here. Optionally, please refer to Figures 1 to 3 , in this embodiment, a rib 112 extending in the up-down direction is provided in the mounting area 11, and a plurality of ribs 112 are arranged at intervals left and right. A plugging groove 113 for inserting the external card 200 is formed between two adjacent ribs 112. The upper end of the plugging groove 113 is open to form the insertion opening 111, and the external card 200 can be inserted into the plugging groove 113 from the insertion opening 111. A plurality of plugging grooves 113 are provided, which can realize the installation and use of multiple external cards 200. At the same time, the plurality of plugging grooves 113 can be respectively set to different sizes to adapt to different models of external cards 200.

[0049] The proximal end of the card pressing base 2 can be rotatably connected to the top of the first connecting portion 12 along the front-to-back axis. When the card pressing base 2 is rotated to the closed position, the card pressing base 2 is located directly above the installation area 11 and closes the plug interface 111. At this time, the card pressing base 2 presses down the folding ear 210 of the external card 200, thereby limiting the external card 200 from being separated from the plug slot 113 at the plug interface 111. When the card pressing base 2 is rotated to the open position, the card pressing base 2 is completely located on the right side of the installation area 11. At this time, the card pressing base 2 is completely staggered with the plug interface 111 in the up-down and up-down directions, and is completely separated from the installation travel range of the external card 200. The external card 200 can be inserted and removed from the plug interface 111 without hindrance. Among them, the card pressing base 2 is usually made of metal.

[0050] The sliding member 3 can be telescopically and slidably arranged at the distal end of the card pressing base 2, and the proximal end of the sliding member 3 is slidably connected to the distal end of the card pressing base 2. The distal end of the sliding member 3 is provided with a buckling portion 31. When the card pressing base 2 is rotated to the closed position, the card pressing base 2 is arranged along the left and right directions. The sliding member 3 is slid to the left to the first position. At this time, the buckling portion 31 on the sliding member 3 is buckled with the buckling portion 131 on the mounting bracket 1, thereby limiting the card pressing base 2 from being rotated open; if the card pressing base 2 is to be opened, it is only necessary to slide the sliding member 3 to the right to the second position. At this time, the buckling portion 31 on the sliding member 3 is separated from the buckling portion 131 on the mounting bracket 1, and the card pressing base 2 can be rotated in the opposite direction to the open position.

[0051] The present invention forms a restriction on the external card 200 by rotating the card pressing base 2 to close the insertion port 111, and makes the buckling portion 31 on the sliding member 3 buckle with the buckling portion 131 on the mounting bracket 1. This connection method can form a higher clamping strength for the external card 200, and at the same time, it is not easy to loosen due to impact forces in other directions after being installed in place, and the structure is safer and more reliable; the card pressing mechanism 100 adopts a sliding unlocking method, and the card pressing base 2 can be rotated to unlock after the sliding member 3 is moved. At this time, the card pressing base 2 is completely out of the installation travel range of the external card 200, making the disassembly and assembly process of the external card 200 smoother and easier to operate.

[0052] The proximal end of the card pressing base 2 can be rotatably connected to the top of the first connecting portion 12 along the front-to-back axis. Figures 1 to 3 In this embodiment, the first connecting portion 12 is provided with a rotating shaft 121 extending along the front-to-back direction, and the proximal end of the card pressing base 2 is rotatably connected to the rotating shaft 121 .

[0053] Further, in this embodiment, a torsion spring (not shown in the figure) is sleeved on the rotating shaft 121. The two elastic arms of the torsion spring respectively abut against the proximal end of the pressing base 2 and the first connecting portion 12. The torsion spring is used to reset the rotation of the pressing base 2. When the buckling portion 31 on the sliding member 3 is separated from the buckling portion 131 on the mounting bracket 1, the pressing base 2 in the closed position can be rotated and reset to the open position through the reset action of the torsion spring.

[0054] Optionally, please refer to Figure 2 , Figure 4 and Figure 5 , in this embodiment, a rotating shaft hole (not shown in the figure) is formed by curling the proximal end of the pressing base 2 toward the distal end of the pressing base 2. The proximal end of the pressing base 2 is rotatably connected to the rotating shaft 121 through the rotating shaft hole, so that the pressing base 2 can rotate more smoothly.

[0055] The sliding member 3 is telescopically slidably disposed at the distal end of the pressing base 2. The sliding member 3 can be directly connected to the distal end of the pressing base 2, or the sliding member 3 can be indirectly connected to the distal end of the pressing base 2. For example, please refer to Figures 4 to 6 , in this embodiment, a mounting base 4 is disposed at one end of the pressing base 2 away from the first connecting portion 12, and the sliding member 3 is slidably connected to the mounting base 4 along the extending direction of the pressing base 2.

[0056] Specifically, the mounting base 4 is fixedly installed at the distal end of the pressing base 2, and the sliding member 3 is indirectly connected to the pressing base 2 through the mounting base 4. The distal end of the pressing base 2 and the mounting base 4 are usually detachably connected, so that the sliding unlocking assembly (the sliding unlocking assembly includes the sliding member 3 and the mounting base 4) can change the number of pressings by adapting to different lengths of the pressing base 2, so as to be universal for the installation of various external cards 200. Among them, the sliding member 3 and the mounting base 4 are usually plastic parts, while the pressing base 2 is usually a metal part. In this way, the combination of metal and plastic has good grounding performance, and also takes into account good hand feeling and appearance.

[0057] Optionally, please refer to Figures 4 to 6 , in this embodiment, the pressing base 2 and the mounting base 4 are connected by a screwing member 6, so that the disassembly and assembly between the pressing base 2 and the mounting base 4 can be more convenient and labor-saving. Among them, the screwing member 6 can be a screw, a riveting pin, etc.

[0058] The sliding member 3 is slidably connected to the mounting base 4. Specifically, please refer to Figures 7 to 9 , in this embodiment, the sliding member 3 is provided with a first limiting groove 32 extending along the sliding direction of the sliding member 3, and one end of the mounting base 4 away from the first connecting portion 12 is inserted into the first limiting groove 32.

[0059] Specifically, one end of the mounting base 4 away from the first connecting portion 12 is defined as the distal end of the mounting base 4, and one end of the mounting base 4 close to the first connecting portion 12 is defined as the proximal end of the mounting base 4. The distal end of the mounting base 4 is inserted into the first limiting groove 32, and the distal end of the mounting base 4 is slidably connected to the inner groove wall of the first limiting groove 32. Through the cooperation between the distal end of the mounting base 4 and the first limiting groove 32, not only can the sliding member 3 be slidably guided, but also the sliding member 3 can be limited.

[0060] There are various ways to provide the first limiting groove 32 on the sliding member 3. For example, the first limiting groove 32 can be a closed groove without a notch. One end of the first limiting groove 32 close to the first connecting portion 12 penetrates through the sliding member 3 to form an entrance of the first limiting groove 32, and the distal end of the mounting base 4 can be inserted into the first limiting groove 32 from the entrance of the first limiting groove 32, and one end of the first limiting groove 32 away from the first connecting portion 12 can be closed or penetrate through the sliding member 3; again, the first limiting groove 32 can also be formed with a notch, and either end of the first limiting groove 32 can be closed or penetrate through the sliding member 3. Optionally, please refer to Figure 3 , Figure 4 and Figure 9 , in this embodiment, the notch of the first limiting groove 32 faces the installation area 11.

[0061] Specifically, both the sliding member 3 and the mounting base 4 have a top surface and a bottom surface in the thickness direction. The top surfaces of the sliding member 3 and the mounting base 4 both face away from the installation area 11, and the bottom surfaces of the sliding member 3 and the mounting base 4 both face the installation area 11. The first limiting groove 32 is provided on the bottom surface of the sliding member 3, and the first limiting groove 32 forms a notch on the bottom surface of the sliding member 3.

[0062] Optionally, please refer to Figures 7 to 9 , in this embodiment, the distal end of the sliding member 3 is thicker than the proximal end of the sliding member 3 to form a stepped surface on the bottom surface of the sliding member 3. The first limiting groove 32 is provided on the bottom surface of the distal end of the sliding member 3, and both ends of the first limiting groove 32 penetrate through the distal end of the sliding member 3. In this way, the distal end of the sliding member 3 and the distal end of the mounting base 4 can be nested together through the first limiting groove 32, thereby reducing the thickness dimension of the sliding unlocking assembly.

[0063] Optionally, please refer to Figures 7 to 9 , in this embodiment, the end of the mounting base 4 away from the first connecting portion 12 is adapted to the shape of the first limiting groove 32. The first limiting groove 32 is a trapezoidal groove with a wider bottom than the notch. Making the distal end of the mounting base 4 and the first limiting groove 32 into a trapezoidal structure can prevent the distal end of the sliding member 3 from detaching from the mounting base 4.

[0064] Optionally, please refer to Figure 7 , Figure 8and Figure 10 In this embodiment, a second limiting groove 41 extending along the sliding direction of the sliding member 3 is provided at one end of the mounting base 4 close to the first connecting portion 12 , and one end of the sliding member 3 close to the first connecting portion 12 is inserted into the second limiting groove 41 .

[0065] Specifically, the proximal end of the sliding member 3 is slidably connected to the inner groove wall of the second limiting groove 41. Through the cooperation between the proximal end of the sliding member 3 and the second limiting groove 41, it can not only play a sliding guiding role for the sliding member 3, but also play a limiting role for the sliding member 3.

[0066] Similarly, like the arrangement of the first limiting groove 32, the second limiting groove 41 can be a closed groove without a notch or a notch. Figure 4 , Figure 6 and Figure 7 In this embodiment, the end of the card pressing base 2 away from the first connection part 12 is provided with a mounting groove 21, and the mounting base 4 is provided at the mounting groove 21. The groove wall of the mounting groove 21 closes at least part of the notch of the second limiting groove 41 to form a limiting space (not shown in the figure), and at least part of the end of the sliding member 3 close to the first connection part 12 is located in the limiting space. The second limiting groove 41 is provided with a notch, and the inner groove wall of the mounting groove 21 closes at least part of the notch of the second limiting groove 41 to form a closed limiting space. The proximal end of the sliding member 3 relies on the limiting space to limit its movement to prevent the proximal end of the sliding member 3 from leaving the slideway.

[0067] Optionally, see Figures 8 to 10 In this embodiment, the end of the sliding member 3 close to the first connecting portion 12 is adapted to the shape of the second limiting groove 41, and the proximal end of the sliding member 3 and the second limiting groove 41 are made into the same shape, so that the second limiting groove 41 has a better limiting effect on the proximal end of the sliding member 3.

[0068] Optionally, see Figure 3 , Figure 6 and Figure 8 In this embodiment, the notch of the second limiting groove 41 faces away from the installation area 11. The second limiting groove 41 is arranged on the top surface of the installation base 4, and the second limiting groove 41 forms a notch on the top surface of the installation base 4.

[0069] Optionally, see Figures 7 to 9 In this embodiment, the proximal end of the mounting base 4 is thicker than the distal end of the mounting base 4 to form a step surface on the top surface of the mounting base 4. One end of the second limiting groove 41 passes through the distal end of the mounting base 4, so that the proximal end of the sliding member 3 and the proximal end of the mounting base 4 can be nested together through the second limiting groove 41, thereby reducing the thickness of the sliding unlocking component.

[0070] Optionally, seeFigures 8 to 10 In this embodiment, the sliding member 3 and the mounting base 4 are respectively provided with a first limiting portion 34 and a second limiting portion 42. The first limiting portion 34 and the second limiting portion 42 face each other in the sliding direction of the sliding member 3. When the sliding member 3 is in the first position, the first limiting portion 34 abuts against the second limiting portion 42.

[0071] Similarly, please refer to Figures 8 to 10 In this embodiment, the sliding member 3 and the mounting base 4 are respectively provided with a third limiting portion 35 and a fourth limiting portion 43. The third limiting portion 35 and the fourth limiting portion 43 face each other in the sliding direction of the sliding member 3. When the sliding member 3 is in the second position, the third limiting portion 35 abuts against the fourth limiting portion 43.

[0072] Specifically, through the arrangements of the first limiting portion 34 and the second limiting portion 42, as well as the third limiting portion 35 and the fourth limiting portion 43, the sliding of the sliding member 3 can be stopped, thereby ensuring the integrity of the sliding stroke of the sliding member 3.

[0073] Further, in this embodiment, the first limiting portion 34 and the third limiting portion 35 are arranged on the part of the sliding member 3 located in the second limiting groove 41, and the inner side wall of the second limiting groove 41 is provided with the second limiting portion 42 and the fourth limiting portion 43. For example, please refer to Figure 7 , Figure 9 and Figure 10 In this embodiment, the part of the sliding member 3 located in the second limiting groove 41 and the second limiting groove 41 are both arranged in a "cross" shape. The sliding member 3 is formed with two first limiting portions 34 and two third limiting portions 35, and the inner side wall of the second limiting groove 41 is formed with two second limiting portions 42 and two fourth limiting portions 43.

[0074] The distal end of the pressing base 2 is provided with a mounting groove 21. Optionally, please refer to Figures 4 to 6 In this embodiment, the pressing base 2 is bent at the two side ends in the front-rear upward direction to form the two side walls of the mounting groove 21 in the groove width direction. The two side walls of the mounting groove 21 are then bent towards each other to form the two notch walls of the mounting groove 21. The notch between the two notch walls of the mounting groove 21 forms the notch of the mounting groove 21. The part of the pressing base 2 opposite to the two notch walls of the mounting groove 21 is the bottom wall of the mounting groove 21. The distal end of the pressing base 2 forms an insertion opening 211 of the mounting groove 21. The proximal end of the mounting base 4 can be inserted into the mounting groove 21 from the insertion opening 211 of the mounting groove 21. By setting the mounting groove 21 in this way, the thickness dimension of the pressing component (the pressing component includes the pressing base 2 and the sliding unlocking component) can be reduced, and a great deal of space in the height direction can be saved.

[0075] The card pressing assembly can solve the problem of fixing the external card 200 in extremely limited space. For example, in this embodiment, the thickness of the main body of the card pressing assembly is only 3.8MM. On the premise of ensuring the basic card pressing function, a sliding unlocking assembly is added to the card pressing assembly to ensure the firmness of the card pressing. At the same time, it occupies a small space, is easy to operate, and is suitable for many scenarios.

[0076] Optionally, see Figures 4 to 6 In this embodiment, the mounting base 4 is located in the mounting groove 21 , and a notch 213 is provided on the bottom wall of the mounting groove 21 corresponding to the distal end of the sliding member 3 .

[0077] Specifically, an operation area 36 is formed on the distal top surface of the sliding member 3 , and the operation area 36 is used for the user to operate and move the sliding member 3 . The operation area 36 can be exposed from the notch 213 , so that the user can press the operation area 36 to move the sliding member 3 .

[0078] For further information, see Figure 4 and Figure 7 In this embodiment, the operating area 36 is provided with an anti-slip pattern 361. The top of the sliding member 3 is provided with an anti-slip pattern 361, which can improve the operating feel. Through the anti-slip effect of the anti-slip pattern 361, the user can move the sliding member 3 with less effort. Among them, the anti-slip pattern 361 can be a convex point, a convex stripe, a groove, etc., for example, see Figure 4 and Figure 7 In this embodiment, the anti-slip pattern 361 includes convex stripes extending in the front-to-back direction, and a plurality of convex stripes are arranged at intervals along the sliding direction of the sliding member 3 .

[0079] Optionally, see Figures 4 to 6 In this embodiment, the mounting groove 21 is formed with an insertion port 211 for inserting the mounting base 4 , and the inner wall of the mounting groove 21 is provided with a limiting protrusion 212 facing the insertion port 211 , and the limiting protrusion 212 abuts against the mounting base 4 .

[0080] Specifically, a portion of a slot wall of the mounting slot 21 is bent toward the inside of the mounting slot 21 to form a limiting protrusion 212, and the limiting protrusion 212 is closer to the proximal end of the pressing base 2 than the mounting base 4. The limiting protrusion 212 abuts against the proximal end of the mounting base 4, thereby realizing the installation positioning between the mounting base 4 and the pressing base 2 in the sliding direction of the sliding member 3.

[0081] Optionally, see Figure 3 and Figure 5 In this embodiment, a first elastic arm 22 is provided on the bottom surface of the card pressing base 2, and the card pressing base 2 abuts against the folding ear 210 of the external card 200 through the first elastic arm 22, so that the card pressing can be ensured to be sufficiently firm.

[0082] Specifically, a part of the notch wall of the installation groove 21 bulges outward to form a first elastic arm 22, so that the first elastic arm 22 has better elastic performance.

[0083] Optionally, please refer to Figure 3 , Figure 5 and Figure 11 , in this embodiment, a second elastic arm 44 is provided on the bottom surface of the installation base 4, and the second elastic arm 44 extends out from the notch of the installation groove 21. The second elastic arm 44 is also used to abut against the folding ear 210 of the external card 200. Moreover, through the cooperation between the second elastic arm 44 and the two notch walls of the installation groove 21, a limiting effect can be exerted on the installation base 4 in the groove width direction of the installation groove 21.

[0084] Optionally, please refer to Figure 7 and Figure 8 , in this embodiment, an elastic member 5 is provided in the second limiting groove 41. The elastic member 5 abuts between the inner side wall of the second limiting groove 41 close to the first connecting portion 12 and the end face of the sliding member 3 close to the first connecting portion 12. After the sliding member 3 slides to the second position, the elastic member 5 can slide the sliding member 3 back to the first position. Among them, the elastic member 5 can be a spring, a soft rubber strip, etc.

[0085] Specifically, please refer to Figures 7 to 9 , in this embodiment, a mounting post 33 protrudes from the end face of the sliding member 3 close to the first connecting portion 12. The elastic member 5 is a spring, and the end of the spring close to the sliding member 3 is sleeved outside the mounting post 33. The provision of the mounting post 33 at the proximal end of the sliding member 3 makes it easier to install the spring.

[0086] When the buckling portion 31 on the sliding member 3 is buckled with the buckling portion 131 on the mounting bracket 1, the rotation of the pressing base 2 can be restricted, and the overall locking function can be completed. Among them, there are various setting methods for the buckling portion 31 and the buckling portion 131. For example, both the buckling portion 31 and the buckling portion 131 can be protrusions. When the pressing base 2 is in the closed position and the sliding member 3 is in the first position, the buckling portion 131 is located above the buckling portion 31; again, please refer to Figure 1 and Figure 2 , in this embodiment, one of the buckling portion 31 and the buckling portion 131 is a positioning hole, and the other is a positioning protrusion. When the pressing base 2 is in the closed position and the sliding member 3 is in the first position, at least a part of the positioning protrusion is inserted into the positioning hole.

[0087] Specifically, please refer to Figure 1 , Figure 2 and Figure 7, in this embodiment, a stop projection is convexly provided on the distal end surface of the sliding member 3, and a stop piece (not shown in the figure) facing the first connecting portion 12 is convexly provided on the top of the second connecting portion 13, and a stop hole is provided through the stop piece.

[0088] The installation process of the external card 200 can be as follows: When the pressing and clamping assembly is opened, the sliding member 3 needs to be toggled to disengage the stop projection from the stop hole, and the pressing and clamping assembly rotates and opens around the rotation axis 121; the external card 200 is inserted into the insertion slot 113, the pressing and clamping assembly is rotated, and the stop projection is snapped into the stop hole to complete the assembly of the external card 200. The pressing and clamping assembly fixes the external card 200 reliably so that it will not slide and shift in the slot.

[0089] The present invention also provides a chassis, which includes a pressing and clamping mechanism that adopts the technical solution of the above embodiment, and thus has the beneficial effects brought by the technical solution of the above embodiment.

[0090] The present invention also provides a server, which includes a chassis, the chassis includes a pressing and clamping mechanism that adopts the technical solution of the above embodiment, and thus has the beneficial effects brought by the technical solution of the above embodiment.
