Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of electronic equipment, and in particular to a limit stop component and electronic equipment. Background Art
[0002] The bus and interface standard module (Peripheral Component Interface Express, PCIE) is usually used as a key hardware configuration to improve the functional requirements of the server. Among them, the commonly used PCIE card specifications are classified by width, mainly into full-height single-width cards and full-height double-width cards. For example, high-performance servers often use full-height double-width cards, such as graphics processing units (GPUs). In addition, with the increase in the weight of PCIE cards, it is often necessary to set up a reinforcement structure to improve the reliability of the relative position fixation between the PCIE card and the server, which is used to prevent the PCIE card from falling out of its corresponding slot during the vibration test.
[0003] In the related art, screw locking is mostly used to improve the fixation between the PCIE card and the server, but there is the problem of inconvenience in assembly and disassembly; at the same time, the adaptability is poor, that is, the same locking structure is difficult to meet the fixation requirements of PCIE cards of different sizes and types at the same time. That is, there are the problems of inconvenience in assembly and disassembly and poor adaptability. Utility Model Content
[0004] The technical solution of the embodiment of the present application is implemented as follows:
[0005] In the first aspect, an embodiment of the present application provides a limit assembly, which is arranged on a bracket of a chassis, and the limit assembly includes a limit piece and a rotating shaft, wherein a first axial hole is provided on the limit piece; the rotating shaft passes through the first axial hole and the second axial hole on the bracket in sequence to rotationally connect the limit piece and the bracket, and the limit piece can be rotated relative to the bracket to a locked position or an unlocked position; when the limit piece is in the locked position, the limit piece abuts against an adapter card inserted on the bracket to prevent the displacement between the adapter card and the bracket along the first direction; when the limit piece is in the unlocked position, the limit piece is disengaged from the abutment with the adapter card inserted on the bracket, so that the adapter card can be inserted into or removed from the card slot on the bracket; wherein the first direction is the insertion and removal direction of the adapter card.
[0006] In the position-limiting assembly provided in the embodiment of the present application, due to the rotational connection between the position-limiting member and the bracket, the position-limiting member can be rotated to different positions relative to the bracket, for example, the position-limiting member rotatably connected to the bracket can be rotated to a locked position or an unlocked position relative to the adapter card, wherein the adapter card can be a PCIE card, a GPU card, etc. Specifically, when the position-limiting member is in the locked position, the position-limiting member can move to abut against the adapter card, such as, along the plug-in and pull-out direction of the adapter card, one end of the position-limiting member can be rotated to abut against an end of the adapter card away from its card slot, so as to limit and prevent the displacement between the adapter card and the bracket along the plug-in and pull-out direction of the adapter card, thereby improving the firmness between the adapter card and the server.
[0007] Among them, when the stopper is in the locking position, the locking position may include a first locking position and a second locking position where the stopper moves to two different positions. Accordingly, the size type of the adapter card may be at least two, such as the adapter card has a first size or a second size of different sizes along its own plug-in direction. In the first locking position, the stopper rotates relative to the bracket to the first locking position along the second direction, such as the first end of the stopper has a first distance from the rotation center of the stopper. In the first locking position, the first end of the stopper is used to abut against and limit the adapter card of the first size type; accordingly, the stopper is rotated in a direction opposite to the second direction. When the stopper is rotated to the second locking position, the first end of the stopper moves to an end opposite to the first end of the stopper in the first locking position. That is, in the first locking position and the second locking position, along the first direction, the distance between the first end of the stopper and the card slot for plugging the adapter card is different, so that the abutment and limiting of adapter cards of different sizes can be met, thereby improving the adaptability of the stopper assembly. At the same time, when the limiting member is in the unlocking position, the limiting member is disengaged from the abutment with the adapter card inserted on the bracket, so that the adapter card can be inserted into or removed from the card slot on the bracket, thus facilitating the disassembly and assembly of the adapter card.
[0008] In a possible implementation of the present application, the two ends of the limit member along its own extension direction respectively have a hand-held portion and a limit portion; when the hand-held portion is operated to rotate the limit member to a locked position, the limit portion abuts against an end of the adapter card away from its plug-in position to prevent displacement between the adapter card and the bracket along a first direction; when the hand-held portion is operated to rotate the limit member to an unlocked position, the limit portion is disengaged from the abutment against an end of the adapter card away from its plug-in position to allow the adapter card to be plugged into or removed from the card slot on the bracket.
[0009] In a possible implementation of the present application, the adapter card is a first adapter card or a second adapter card, wherein along the first direction, the length of the first adapter card is less than the length of the second adapter card; the locking position includes a first locking position and a second locking position, and the limit member can be rotated to the first locking position along the second direction or to the second locking position along the third direction, and the third direction is opposite to the second direction; in the state where the adapter card is the first adapter card, when the limit member is in the first locking position, the limit portion abuts against one end of the first adapter card away from its plug-in place, and the limit portion faces the plug-in direction of the first adapter card; in the state where the adapter card is the second adapter card, when the limit member is in the second locking position, the limit portion abuts against one end of the second adapter card away from its plug-in place, and the limit portion faces the removal direction of the second adapter card.
[0010] In a possible implementation of the present application, the limiting member includes a flat plate portion, a first bent portion and a second bent portion; the first bent portion and the second bent portion are respectively connected to two opposite ends of the flat plate portion in the extension direction thereof; a limiting groove is provided on the bracket for limiting the second bent portion from moving toward an unlocking position; wherein the first bent portion protrudes from the flat plate portion, and the bending direction of the first bent portion is toward the outside of the bracket, and the bending direction of the second bent portion is opposite to that of the first bent portion; the first bent portion is a hand-holding portion, and the second bent portion is a limiting portion; when the adapter card is the first adapter card, when the limiting member is in the first locking position, the second bent portion extends into the limiting groove and abuts against an end of the first adapter card away from its insertion position.
[0011] In a possible implementation of the present application, the difference between the length of the second adapter card and the length of the first adapter card along the first direction is twice the maximum distance from the second bending portion to its rotation center.
[0012] In a possible implementation of the present application, the plane where the flat plate portion is located is perpendicular to the rotation center axis of the limiting member, and is perpendicular to the plane where the adapter card is located.
[0013] In a possible implementation of the present application, an end of the rotating shaft away from the limiting member has a flange, and the flange cooperates and abuts against a side edge of the limiting member.
[0014] In a possible implementation of the present application, the limiting member is made of elastic material.
[0015] In a second aspect, an embodiment of the present application further provides an electronic device, which includes a chassis, a bracket, a card slot, and a position limiting assembly of any one of the first aspects. The bracket is arranged on the chassis for carrying electronic devices; the position limiting assembly is arranged on the bracket; and the card slot is arranged on the bracket for installing an adapter card. Since the electronic device in the embodiment of the present application adopts the position limiting assembly of any one of the first aspects, it has the same technical effect, that is, it has the advantages of convenient disassembly and assembly and strong adaptability.
[0016] In a possible implementation of the present application, the bracket is provided with an adapter card bracket, which is used to install a limit assembly; there are multiple second axial holes, and the multiple second axial holes are arranged on the adapter card bracket at intervals; the rotating shaft passes through the first axial hole and one of the multiple second axial holes in sequence to rotatably connect the limit member and the bracket.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0035] The present application embodiment provides an electronic device, referring to Figure 1 , Figure 8 and Fig.10 The electronic device includes a chassis 100, a bracket 1, a card slot 14 and a limit assembly. Here, there are many types of commonly used electronic devices, such as servers, desktop computers, laptop computers, tablet computers, etc. It should be noted that in the embodiments of the present application, the type of electronic device is not limited. In order to vividly illustrate the electronic device provided in the embodiments of the present application, the electronic device can be taken as a server as an example.
[0036] For example, refer to Figure 1 and Figure 8 The server is usually placed in a cabinet. In addition to the most basic motherboard, the server also includes a chassis 100 and electronic devices, among which a bracket 1 is provided on the chassis 100. Here, the bracket 1 can be screwed, clamped or integrally formed on the wall of the chassis 100. The bracket 1 is used to carry electronic devices such as a motherboard, a PCIE card, an input / output (IO) control chip, and a disk array. In addition, a card slot 14 is provided on the bracket 1. Here, the card slot 14 can be a plug-in slot provided on the server motherboard for plugging and installing an adapter card 4. The adapter card 4 can refer to a riser card, a GPU, a memory card, etc. plugged into the plug-in slot.
[0037] With the development of new infrastructure such as cloud computing and big data, the performance requirements for servers are getting higher and higher, and various heterogeneous accelerations have been developed one after another. For example, PCIE card is a network card with a PCIE interface, which is used as an expansion port in the motherboard-level connection. The expansion card based on PCIE can be inserted into the card slot 14 corresponding to the PCIE in the server motherboard to realize a series of point-to-point connections to control the data flow.
[0038] Currently, there are many types of PCIE card designs, which usually have a variety of different specifications and sizes, such as full height half length (FHHL) card, full height full length (FHFL) card, low profile (LP) card, etc. Here, full height or half height card can also be respectively referred to as full height single width card or full height double width card, that is, it is understood that along the plug-in direction of the PCIE card, there are two specifications of PCIE cards with different sizes. For example, the size of the full height single width card along the plug-in direction is often half the size of the full height double width card. Among them, as the weight of the PCIE card increases, a reinforcement structure is often required to improve the relative position of the PCIE card and the server, so as to prevent the PCIE card from falling out during the vibration test. To this end, the related art has adopted a method of screw locking to improve the fixation between the PCIE card and the server bracket, but there is a problem of inconvenient disassembly and assembly, such as it is often necessary to turn the server upside down to remove the screws; at the same time, the adaptability is poor, that is, the same locking structure is difficult to simultaneously meet the fixing requirements of full-height single-width cards and full-height double-width cards of different sizes and types. For example, when removing the full-height single-width card to replace it with a full-height double-width card, it is often necessary to change the tightening position of the screws or the position of the locking structure, that is, there are problems of inconvenient disassembly and assembly and poor adaptability.
[0039] To this end, the present application also provides a limit assembly, referring to Figure 1 , Figure 2 , Figure 5 and Fig. 9 , the limit assembly is arranged on the bracket 1 of the chassis 100. The limit assembly includes a limit member 2 and a rotating shaft 3, wherein the limit member 2 is provided with a first shaft hole 21; the rotating shaft 3 sequentially passes through the first shaft hole 21 and the second shaft hole 11 on the bracket 1 to rotatably connect the limit member 2 with the bracket 1, and the limit member 2 can be rotated to a locked position or an unlocked position relative to the bracket 1; when the limit member 2 is in the locked position, the limit member 2 abuts against the adapter card 4 plugged into the bracket 1 to prevent the adapter card 4 from moving along the first direction with the bracket 1; when the limit member 2 is in the unlocked position, the limit member 2 is disengaged from the abutment with the adapter card 4 plugged into the bracket 1, so that the adapter card 4 can be plugged into or removed from the card slot 14 on the bracket 1; wherein the first direction is the plugging and unplugging direction of the adapter card 4.
[0040] In the embodiment of the present application, the specific structure of the limiter 2 is not limited. For example, the limiter 2 can be roughly in the form of a sheet structure, or a special-shaped member; the extension direction of the limiter 2 can be parallel to the first direction. The distances from the center of the first axial hole 21 on the limiter 2 to the two opposite ends of the limiter 2 along its own extension direction can be different. For example, one end of the limiter 2 is the first end of the limiter 2, the first end of the limiter 2 has a first distance from the rotation center of the limiter 2, the second end of the limiter 2 has a second distance from the rotation center of the limiter 2, and the first distance is different from the second distance. In this way, when the first end of the limiter 2 rotates relative to the bracket 1, the distance between the first end of the limiter 2 and the card slot 14 is different, so that the first end of the limiter 2 can be limitedly abutted against the adapter card 4 of different sizes along the first direction. The portion of the stopper 2 excluding the first end can be arranged away from the adapter card 4, that is, the first end of the stopper 2 can be used to limit and abut the adapter card 4, and the portion of the stopper 2 excluding the first end can avoid interference and collision with the adapter card 4 during the rotation of the stopper 2. In addition, the material of the stopper 2 is not limited, and can be a hard plastic material, an elastic material, etc.
[0041] In the embodiment of the present application, the specific structure of the rotating shaft 3 is not limited. For example, both ends of the rotating shaft 3 along its axial direction may have elastic flanges, so that after the rotating shaft 3 is inserted into the first axial hole 21 and the second axial hole 11 in sequence, the flanges on both sides of the rotating shaft 3 are used to limit and prevent the rotating shaft 3 from slipping out of the first axial hole 21 and the second axial hole 11; or the rotating shaft 3 may be a screw, and the two ends of the screw along its own axial direction have external threads. After the screw passes through the first axial hole 21 and the second axial hole 11 in sequence, the nuts screwed with the external threads are tightened at the opposite ends of the screw along its own axial direction, respectively, to achieve the rotational connection between the limiter 2 and the bracket 1. In addition, a damping structure may also be provided on the rotating shaft 3, which is used to keep the limiter 2 in the locked position when the limiter 2 is rotated to the locked position; or keep the limiter 2 in the unlocked position when the limiter 2 is rotated to the unlocked position.
[0042] In the limiting assembly provided in the embodiment of the present application, due to the rotational connection between the limiting member 2 and the bracket 1, the limiting member 2 can be rotated to different positions relative to the bracket 1, wherein an adapter card 4 for improving the performance of the electronic device is inserted in the card slot 14 on the bracket 1, and the adapter card 4 can be a PCIE card, a GPU card, etc., for example, the limiting member 2 rotatably connected to the bracket 1 can be rotated to a locked position or an unlocked position relative to the adapter card 4. Specifically, when the limiting member 2 is in the locked position, the limiting member 2 can move to abut against the adapter card 4, such as, along the plug-in and pull-out direction of the adapter card 4, one end of the limiting member 2 can be rotated to abut against the end of the adapter card 4 away from its card slot 14, so as to limit and prevent the displacement between the adapter card 4 and the bracket 1 along the plug-in and pull-out direction of the adapter card 4, thereby improving the firmness of the adapter card 4 inserted in the card slot 14.
[0043] Among them, when the limit member 2 is in the locking position, here, the locking position can include a first locking position and a second locking position where the limit member 2 is in two different positions. Correspondingly, the size types of the adapter card 4 can be at least two, such as the adapter card 4 has a first size or a second size along its own plug-in direction. When in the first locking position, the limit member 2 rotates relative to the bracket 1 along the second direction to the first locking position, and one end of the limit member 2 along its own extension direction, such as the first end of the limit member 2, has a first distance from the rotation center of the limit member 2. In the first locking position When the position limiter 2 is in the first locking position, it is used to abut against the adapter card 4 of the first size type; correspondingly, when the position limiter 2 is rotated to the second locking position in the direction opposite to the second direction, the first end of the position limiter 2 moves to the end opposite to the first end of the position limiter 2 in the first locking position, that is, in the first locking position and the second locking position, the distance between the first end of the position limiter 2 and the card slot 14 is different, so that the position limiter 2 can also be used to abut against the adapter card 4 of the second size type, so that the position limiter 2 can meet the abutment and limit of the adapter cards 4 of different size types, thereby improving the adaptability of the position limiter assembly. At the same time, when the position limiter 2 is in the unlocking position, the position limiter 2 is disengaged from the adapter card 4 plugged into the bracket 1, so that the adapter card 4 can be plugged into or pulled out of the card slot 14 on the bracket 1. In this way, on the basis of meeting the strong adaptability of the position limiter assembly, it is also convenient for the disassembly and assembly of the adapter card 4.
[0044] For example, refer to Fig. 9 and Fig.10The limiting member 2 has a hand-holding portion and a limiting portion at both ends along its own extension direction; here, the hand-holding portion is the first bending portion 23, and the limiting portion is the second bending portion 24. When the hand-holding portion is operated to rotate the limiting member 2 to the locked position, the limiting portion abuts against the end of the adapter card 4 away from its plug-in position to prevent the displacement between the adapter card 4 and the bracket 1 along the first direction; when the hand-holding portion is operated to rotate the limiting member 2 to the unlocked position, the limiting portion is disengaged from the abutment against the end of the adapter card 4 away from its plug-in position, so that the adapter card 4 can be plugged into or removed from the card slot 14 on the bracket 1. Here, the rotation direction of the limiting member 2 from the locked position to the unlocked position is opposite to the rotation direction from the unlocked position to the locked position. Refer to Figure 1 , when the stopper 2 is in the unlocked position, the extension direction of the stopper 2 may be perpendicular to the direction of the plane where the adapter card 4 is located; Figure 2 and Figure 5 When the limiting member 2 is in the locking position, the extending direction of the limiting member 2 may be parallel to the plugging direction of the adapter card 4 .
[0045] In some embodiments, reference Figure 3 and Figure 6 , the adapter card 4 is a first adapter card 41 or a second adapter card 42, wherein along the first direction, the size of the first adapter card 41 is smaller than the size of the second adapter card 42, such as the first adapter card 41 is a full-height single-width card, and the second adapter card 42 is a full-height double-width card, where the first direction is parallel to the width direction of the adapter card 4; the locking position includes a first locking position and a second locking position, and the limit member 2 can be rotated along the second direction to the first locking position or along the third direction to the second locking position, and the third direction is opposite to the second direction. Figure 2 , Figure 3 and Figure 4 , when the adapter card 4 is the first adapter card 41, when the limiting member 2 is in the first locking position, the limiting portion abuts against an end of the first adapter card 41 away from its plug-in position, and the limiting portion faces the plug-in direction of the first adapter card 41; refer to Figure 5 , Figure 6 and Figure 7 , when the adapter card 4 is the second adapter card 42, when the limiting member 2 is in the second locking position, the limiting portion abuts against the end of the second adapter card 42 away from the plug-in position, and the limiting portion faces the removal direction of the second adapter card 42. Here, the removal direction of the second adapter card 42 is parallel to the first direction and opposite to the plug-in direction of the second adapter card 42; the limiting portion can be understood as the second bending portion 24 of the limiting member 2.
[0046] Among them, in the embodiments of the present application, for the convenience of distinguishing the description, refer to Figure 3 and Figure 4, the rectangular frame filled with dots indicates that the adapter card 4 is a full-height single-width card, that is, the first adapter card 41 with a smaller size along the first direction; correspondingly, refer to Figure 6 and Figure 7 , the rectangular frame filled with oblique lines indicates that the adapter card 4 is a full-height double-width card, that is, a second adapter card 42 with a larger size along the first direction.
[0047] Continue, refer to Figure 8 , Fig. 9 and Fig.10 The limiting member 2 includes a flat plate portion 22, a first bent portion 23 and a second bent portion 24; the first bent portion 23 and the second bent portion 24 are respectively connected to two opposite ends of the flat plate portion 22 in its own extending direction; the bracket 1 is provided with a limiting groove 12 for limiting the second bent portion 24 to move toward the unlocking position; wherein the first bent portion 23 protrudes from the flat plate portion 22, and the bending direction of the first bent portion 23 is toward the outside of the bracket 1, and the bending direction of the second bent portion 24 is opposite to that of the first bent portion 23; the first bent portion 23 is a hand-holding portion, and the second bent portion 24 is a limiting portion; when the adapter card 4 is the first adapter card 41, when the limiting member 2 is in the first locking position, the second bent portion 24 extends into the limiting groove 12 and abuts against an end of the first adapter card 41 away from its plug-in position. For the sake of convenience, the end of the limiter 2 farther from the rotation center is called the first end of the limiter 2, and the end of the limiter 2 closer to the rotation center is called the second end of the limiter 2. The second bending portion 24, i.e., the limiter, is formed at the first end of the limiter 2; the first bending portion 23, i.e., the hand-held portion, is formed at the second end of the limiter 2.
[0048] In some embodiments, the difference in length between the second adapter card 42 and the first adapter card 41 along the first direction is twice the maximum distance from the second bent portion 24 to the rotation center thereof. Specifically, when the stopper 2 is in the first locking position, that is, when the second bent portion 24 of the corresponding stopper 2 abuts against the first adapter card 41 for limiting, that is, the second bent portion 24 of the corresponding stopper 2 is located on the side close to the card slot 14. At this time, the stopper 2 can be rotated in the direction opposite to the rotation direction of the stopper 2 from the unlocking position to the first locking position, so that the second bent portion 24 of the stopper 2 is rotated to the end away from the card slot 14, that is, at this time, the second bent portion 24 of the stopper 2 moves to the farthest end from the card slot 14, which can be used to abut against the second bent portion 24 of the stopper 2 to limit the second adapter card 42 with a larger size along the first direction. If the difference in length between the second adapter card 42 and the first adapter card 41 along the first direction is designed to be twice the maximum distance from the second bend portion 24 to the rotation center thereof, when the second bend portion 24 of the stopper 2 moves from the closest point to the card slot 14 to the farthest point from the card slot 14, the further distance moved by the second bend portion 24 of the stopper 2 from the card slot 14 along the first direction is just twice the maximum distance from the second bend portion 24 to the rotation center thereof, and the second bend portion 24 of the stopper 2 just moves to abut against the end of the second adapter card 42 away from the card slot 14. The above arrangement can satisfy that the second bend portion 24 of the stopper 2 is used to abut against the first adapter card 41 or the second adapter card 42 of different specifications along the first direction to prevent the first adapter card 41 or the second adapter card 42 from being displaced relative to the bracket 1 along the first direction.
[0049] Reference Figure 1 and Fig.10 , the plane where the flat plate portion 22 is located is perpendicular to the rotation center axis of the limiter 2, and is perpendicular to the plane where the adapter card 4 is located. In this way, the flat plate portion 22 can be easily avoided from the movement path of the adapter card 4 when it is plugged in and out, and the stability of the limiter 2 during rotation can be increased. Furthermore, a flange (not shown in the figure) can be provided at one end of the shaft 3 away from the limiter 2, and the flange is matingly abutted with the side of the limiter 2. In this way, the flange on the limiter 2 can be used to prevent the limiter 2 from escaping from the bracket 1 along the axial direction of the shaft 3, so as to further improve the reliability of the limiter assembly.
[0050] In some embodiments, reference Figure 1 and Fig. 9The bracket 1 has an adapter card bracket 13, which is used to install the limit assembly; there are multiple second axial holes 11, and the multiple second axial holes 11 are arranged on the adapter card bracket 13 at intervals; the rotating shaft 3 passes through the first axial hole 21 and one of the multiple second axial holes 11 in sequence to rotatably connect the limit member 2 to the bracket 1. Among them, the card slot 14 for installing the adapter card 4 can be set on the motherboard of the electronic device, so that the adapter card 4 can communicate with the motherboard when inserted into the card slot 14. The adapter card bracket 13 can also be provided with an elastic card protrusion 131, which can be a flange structure protruding from the groove wall of the limit groove 12, and can be used to engage with at least part of the limit member 2 to limit, thereby reducing the possibility of the limit member 2 falling off the bracket 1.
[0051] The adapter card bracket 13 can be arranged at an end opposite to the card slot 14, and the adapter card bracket 13 can be arranged to avoid the plug-in and pull-out direction of the adapter card 4. For example, the adapter card bracket 13 is arranged at one end in the width direction of the adapter card 4 itself. In addition, a plurality of second axial holes 11 can be arranged on the adapter card bracket 13, and the plurality of second axial holes 11 can be arranged at intervals along the first direction; or a part of all the second axial holes 11 can be arranged at intervals along the first direction, and the other part can be arranged at intervals along the direction perpendicular to the plane where the adapter card 4 is located. In this way, it is convenient to make the limiting member 2 in a plurality of different positions relative to the bracket 1, and then it is convenient to limit more adapter cards 4 of different sizes and types through the limiting component.
