[0002] In the related art, in order to detachably connect two components, a threaded fit form is usually used for connection, for example, bolts or screws are used for connection. In this case, firstly, each installation and disassembly requires the use of tools such as screwdrivers or wrenches for screwing, and the operation is relatively cumbersome. Secondly, threaded holes need to be provided for the bolts or screws on the two components to be connected, specifically, they can be opened on the bodies of the two components to be connected. In addition, the bolts or screws are likely to fall and be lost during the disassembly and assembly process. Especially when the two components to be connected are electrical components or precision mechanical components, the lost bolts or screws are likely to pose potential hazards. Summary of the Utility Model

[0003] The purpose of the present disclosure is to provide a quick-release component, a board module, and an electronic device to at least partially solve the problems existing in the related art.

[0004] To achieve the above purpose, the present disclosure provides a quick-release component, including: a fixed bracket; a rotating shaft installed on the fixed bracket; and a buckle rotatably installed on the fixed bracket through the rotating shaft. The buckle is provided with a rotating shaft hole for the rotating shaft to pass through, and the rotating shaft hole has a locking position and an unlocking position for accommodating the rotating shaft respectively, wherein the rotating shaft is adapted to switch positions between the locking position and the unlocking position.

[0005] Optionally, a protrusion is provided in the rotating shaft hole, and the locking position and the unlocking position are located on both sides of the protrusion. Wherein, the protrusion is used to limit the rotating shaft in the locking position or the unlocking position, and the protrusion can allow the rotating shaft to move from one of the locking position or the unlocking position to the other when being squeezed.

[0006] Optionally, the wall surface of the protrusion facing the locking position is configured as a first inclined surface for guiding the movement of the rotating shaft, and the wall surface of the protrusion facing the unlocking position is configured as a second inclined surface for guiding the movement of the rotating shaft.

[0007] Optionally, the second inclined surface is configured as a first arc surface adapted to the radian of the rotating shaft.

[0008] Optionally, the rotating shaft hole is opened at a position of the buckle close to the first end, the locking position is farther from the first end than the unlocking position, and the outer contour of the first end is configured as a second arc surface.

[0009] Optionally, a convex portion is provided on an outer wall of the snap fastener at a position corresponding to the unlocking position.

[0010] Optionally, the convex portion is elastic.

[0011] Optionally, the number of the snap fasteners is multiple.

[0012] Optionally, the fixing bracket includes a back plate, and a plurality of protruding side plates are connected to the back plate. Each side plate is respectively provided with a through hole for the rotation shaft to pass through, and the snap fastener is installed between two adjacent side plates.

[0013] Optionally, it further includes a limiting member detachably installed at an end of the rotation shaft for restricting axial movement of the rotation shaft.

[0014] According to a second aspect of the present disclosure, a board module is provided, including a board, a board bracket, and the above-mentioned quick-release assembly. The fixing bracket is fixed to the board bracket, and the snap fastener is used to press and fix the board to the board bracket and / or release the board from the board bracket.

[0015] Optionally, the board includes a board strip. When the rotation shaft is at the locking position, the rotation of the snap fastener is interfered to press and fix the board strip to the board bracket.

[0016] Optionally, at least a part of the board strip and the board bracket are stacked in the disassembly and assembly direction of the board, and the snap fastener presses and fixes the board strip along the disassembly and assembly direction. Wherein, one of the board strip and the board bracket is formed with a protruding structure extending along the disassembly and assembly direction, and the other is formed with an opening matching the protruding structure to limit movement of the board strip relative to the board bracket in a plane perpendicular to the disassembly and assembly direction.

[0017] According to a third aspect of the present disclosure, an electronic device is provided, including the above-mentioned board module.

[0018] With the above technical solution, the rotating shaft hole is an elongated hole with a locking position and an unlocking position. Therefore, when the rotating shaft is located at the locking position and the unlocking position and rotates with the rotating shaft as the axis of rotation, the rotation radius of the snap (the range swept by the outer contour during rotation) is different, and whether it can rotate smoothly depends on the installation position of the quick-release component and the structure of the surrounding components. During use, it is specifically configured such that the snap can rotate freely when the rotating shaft is at the unlocking position, and the rotation of the snap can be restricted when it is at the locking position. By controlling the switching of the rotating shaft between the unlocking position and the locking position, the snap can be selectively pressed and fixed on the component to be disassembled and assembled (locking position) or the component to be disassembled and assembled can be released (unlocking position), thereby realizing the quick pressing and fixing, disassembly and assembly of the component to be disassembled and assembled. The operation is quick and convenient, without the need for tools, and locking and unlocking can be achieved manually. In addition, during the unlocking and locking processes, there is no need to repeatedly disassemble and assemble screws or bolts, which can avoid potential hazards to the component to be disassembled and assembled caused by the loss of screws or bolts due to dropping.

[0019] Other features and advantages of the present disclosure will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Description of the Embodiment

[0036] The following will describe the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present disclosure, and are not intended to limit the present disclosure.

[0037] In the present disclosure, unless otherwise stated, the orientation terms "inside, outside" are based on the structure of the relevant components themselves. For example, the protrusion is provided "inside" the rotating shaft hole, which means that the protrusion is provided in the accommodation space of the rotating shaft hole.

[0038] In addition, in the present disclosure, the terms "first", "second", etc. are used to distinguish one element from another, and do not have sequentiality and importance. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0039] Refer toFigures 1 - 13 The present disclosure exemplarily shows a quick-release component, including a fixed bracket 1, a rotating shaft 2 installed on the fixed bracket 1, and a buckle 3 rotatably installed on the fixed bracket 1 through the rotating shaft 2. Among them, the buckle 3 can rotate relative to the rotating shaft 2, or the rotating shaft 2 can drive the buckle 3 to rotate relative to the fixed bracket 1 together. The buckle 3 is provided with a rotating shaft hole 4 for the rotating shaft 2 to pass through, and the rotating shaft hole 4 has a locking position 41 and an unlocking position 42 for accommodating the rotating shaft 2 respectively. Among them, the rotating shaft 2 is adapted to switch positions between the locking position 41 and the unlocking position 42. The present disclosure does not limit the specific structure of the fixed bracket 1, as long as it can install the rotating shaft 2 and enable the buckle 3 to be rotatably installed on the fixed bracket 1 through the rotating shaft 2. The present disclosure does not limit how the rotating shaft 2 switches between the locking position 41 and the unlocking position 42. For example, an external force can be applied to directly move the rotating shaft 2 between the locking position and the unlocking position. Or, an external force can also be applied to control the movement of the buckle 3 to indirectly achieve the movement of the rotating shaft 2. The specific structure of the rotating shaft hole 4 will be introduced below and will not be elaborated here.

[0040] It should be noted that the present disclosure does not limit the application scenario of the quick-release component. It can be used for any component that needs to be quickly disassembled. When in use, it can be fixed to the component to be disassembled and assembled by the buckle 3 to restrict its movement to achieve locking. When disassembly is required, rotating the buckle 3 to release the component to be disassembled and assembled can achieve its disassembly.

[0041] By using the above technical solution, the rotating shaft hole 4 is an elongated hole with a locking position 41 and an unlocking position 42. Therefore, when the rotating shaft 2 is located at the locking position 41 and the unlocking position 42 and rotates with the rotating shaft 2 as the axis of rotation, the rotation radius of the buckle 3 (the range swept by the outer contour during rotation) is different. Whether it can rotate smoothly depends on the installation position of the quick-release component and the structure of the surrounding components. When in use, it is specifically installed and configured so that the buckle 3 can rotate freely when the rotating shaft 2 is located at the unlocking position 42, and the rotation of the buckle 3 can be restricted when it is located at the locking position 41. By controlling the switching of the rotating shaft 2 between the unlocking position 42 and the locking position 41, the buckle 3 can be selectively fixed to the component to be disassembled and assembled (locking position) or release the component to be disassembled and assembled (unlocking position), thereby realizing the quick fixation and disassembly of the component to be disassembled and assembled. The operation is quick and convenient, without the need to use tools, and locking and unlocking can be achieved manually. In addition, during the unlocking and locking processes, there is no need to repeatedly disassemble and assemble screws or bolts, which can avoid potential hazards caused by the loss of screws or bolts to the component to be disassembled and assembled.

[0042] In an embodiment of the present disclosure, in order to make the rotation radius of the buckle 3 at the locking position 41 and the unlocking position 42 have a large difference, the rotating shaft hole 4 can be an elongated hole. It should be explained that the "elongated" here means that the cross-section of the rotating shaft hole 4 along the axis perpendicular to the axis of the rotating shaft hole 4 is generally constructed as an elongated shape. For example, a rectangle, an ellipse, or an irregular shape.

[0043] Referring to Figures 3 - 5 , in an embodiment of the present disclosure, a protrusion 43 may be provided in the rotating shaft hole 4, and the locking position 41 and the unlocking position 42 may be located on both sides of the protrusion 43, that is, in the extending direction of the rotating shaft hole 4, the protrusion 43 is located between the locking position 41 and the unlocking position 42. Among them, the protrusion 43 is used to limit the rotating shaft 2 at the locking position 41 or the unlocking position 42, and can allow the rotating shaft 2 to move from one of the locking position 41 or the unlocking position 42 to the other when being squeezed. By providing the protrusion 43, the rotating shaft hole 4 is divided into the locking position 41 and the unlocking position 42, and the rotating shaft 2 can be fixed at the locking position 41 or the unlocking position 42, avoiding the situation of accidental unlocking or accidental locking. The protrusion 43 may be integrally formed with the buckle 3, or may also be installed in the rotating shaft hole 4 by means of bonding or the like. It should be noted that in order to enable the protrusion 43 to be squeezed by the rotating shaft 2 and allow the rotating shaft 2 to move from one of the locking position 41 and the unlocking position 42 to the other when an external force is applied, the protrusion 43 may be configured to be elastic. Alternatively, in some other embodiments, the buckle 3 may also be configured to be elastically deformed so that when an external force is applied, the rotating shaft 2 can squeeze the buckle 3 and move from one of the locking position 41 and the unlocking position 42 to the other. Or, in some other embodiments, the protrusion 43 may also be a rigid structure, which is configured to undergo a mechanical structure change when being squeezed so that the protrusion 43 generates a displacement and the gap between the protrusion 43 and the inner wall of the buckle 3 becomes larger, enabling the rotating shaft 2 to move from one of the locking position 41 or the unlocking position 42 to the other.

[0044] The present disclosure does not limit the structure of the protrusion 43. For example, in Figure 3 the illustrated embodiment, the wall surface of the protrusion 43 facing the locking position 41 may be configured as a first inclined surface 431 for guiding the movement of the rotating shaft 2, and the wall surface of the protrusion 43 facing the unlocking position 42 may be configured as a second inclined surface 432 for guiding the movement of the rotating shaft 2. By providing the first inclined surface 431 and the second inclined surface 432, when the rotating shaft 2 moves from one of the locking position 41 and the unlocking position 42 to the other, the first inclined surface 431 or the second inclined surface 432 can play a guiding role in the movement of the rotating shaft 2 so that it moves to the interval position between the protrusion 43 and the inner wall of the rotating shaft hole 4 and can realize the movement from one of the locking position 41 and the unlocking position 42 to the other. For example, the cross-section of the protrusion 43 may be configured as an isosceles trapezoid, and the two hypotenuses of the isosceles trapezoid are respectively used as the first inclined surface 431 and the second inclined surface 432.

[0045] The present disclosure does not limit the inclination angle and shape of the first inclined surface 431 and the second inclined surface 432. For example, in Figure 3In the illustrated embodiment, the second inclined surface 432 may be configured as a first arc surface 44 adapted to the radian of the rotation axis 2. With such a design, it is beneficial for the snap 3 to rotate relative to the rotation axis 2. The first arc surface 44 can play a role in guiding the rotation, improving the stability of the rotation process. It should be noted that, in order to improve the stability of the rotation process of the snap 3, in the embodiments of the present disclosure, other positions of the inner contour of the unlocking position 42 may also be set as arc surfaces adapted to the rotation axis 2, and may form a connection with the aforementioned first arc surface 44. In Figure 3 In the illustrated embodiment, the first inclined surface 431 may be configured as an inclined plane. In addition, in some other embodiments, it may also be configured as an arc surface, and the present disclosure does not limit this.

[0046] Referring to Figures 1 - 6 , in the embodiments of the present disclosure, the rotating shaft hole 4 may be opened at a position of the snap 3 close to the first end 32. The locking position 41 is farther from the first end 32 than the unlocking position 42. The outer contour of the first end 32 may be configured as a second arc surface 321. By configuring the outer contour of the first end 32 as the second arc surface 321, the range swept by the outer contour of the first end 32 during the rotation of the snap 3 at the unlocking position 42 can be reduced, reducing the rotational interference of other components on the snap 3 when it is in the unlocking position 42, facilitating the arrangement of the quick-release assembly, and it can be closer to other components to a greater extent, improving the flexibility of the arrangement. For example, when its outer contour is square, when the snap 3 rotates, its corner positions will interfere with the board card bracket 7 (a relatively large interval needs to be maintained, which is not conducive to the arrangement).

[0047] Furthermore, the center line of the second arc surface 321 may coincide with the central axis of the rotation axis 2 when it is in the unlocking position 42. With such a design, when the rotation axis 2 is in the unlocking position 42, since the outer contour of the first end 32 coincides with the central axis of the rotation axis 2, when the snap 3 rotates, the rotation path of the outer contour of the first end 32 coincides with its outer contour and will not exceed the outer contour to interfere with the surrounding components and limit the rotation. For example, in 6, when installing the quick-release assembly on the board card bracket 7, no matter how the snap 3 rotates, the outer contour of its first end 32 will not interfere with the board card bracket 7. When the rotation axis 2 is in the locking position 41, the rotation path of the first end 32 exceeds its outer contour and interferes with the board card bracket 7 and cannot rotate.

[0048] In the embodiments of the present disclosure, the snap 3 may be made of an elastic material, such as plastic, rubber, etc. With such a design, when the rotation axis 2 is in the unlocking position, even if there is interference within an allowable range between the first end 32 and the surrounding components (such as the board card bracket 7) during rotation, the snap 3 can be slightly deformed by applying an external force to achieve rotation. When the rotation axis 2 is in the locking position, since the interference amount during its rotation is large, even if the snap 3 has elasticity, it cannot meet the rotation conditions.

[0049] Reference Figures 3 - 6 , in an embodiment of the present disclosure, a convex portion 31 may be provided at a position on the outer wall of the snap 3 corresponding to the unlocking position 42. By providing the convex portion 31, the outer wall of the snap 3 can abut against surrounding components (such as the board card bracket 7), so that when the rotating shaft 2 is located at the locking position 41, a lever action can be formed through the rotating shaft 2 to press the snap 3 against the component to be disassembled and assembled (such as Figure 6 the board card strip 8 shown in). In the present disclosure, the convex portion 31 may be integrally formed with the snap 3. In addition, in some other embodiments, the convex portion 31 may also be bonded to the snap 3.

[0050] Furthermore, in an embodiment of the present disclosure, the outer contour of the convex portion 31 may be configured as an arc to facilitate the rotation of the snap 3.

[0051] In an embodiment of the present disclosure, the convex portion 31 may have elasticity. Designed in this way, the convex portion 31 can elastically abut against the surrounding components, and the elastic abutment makes the aforementioned "lever action" more stable, which can avoid the rotation of the snap 3 driven by the vibration of the component to be disassembled and assembled and the impact noise generated with the surrounding components.

[0052] In order to lock or unlock a plurality of components to be disassembled and assembled to achieve quick disassembly and assembly, in an embodiment of the present disclosure, the number of snaps 3 may be multiple, for example, two, three, etc. The multiple snaps 3 may be independent of each other or may be connected as a whole to enable synchronous rotation.

[0053] The present disclosure does not limit the structure of the fixed bracket 1. For example, in the Figure 2 shown embodiment, the fixed bracket 1 may include a back plate 11, and a plurality of protruding side plates 12 may be connected to the back plate 11. Each side plate 12 may be respectively provided with a through hole 121 for the rotating shaft 2 to pass through, and the snap 3 may be installed between two adjacent side plates 12. When the number of side plates 12 is three, the number of snaps 3 is 2; when the number of side plates 12 is 5, the number of snaps 3 is 4. The side plates 12 may be integrally formed with the back plate 11, and the back plate 11 is used for installing on surrounding components (such as the board card bracket 7).

[0054] In order to prevent the rotating shaft 2 from axially moving and disengaging from the fixed bracket 1, refer to Figure 2 and Figure 7, in an embodiment of the present disclosure, it may further include a limiting member 21 detachably mounted at the end of the rotating shaft 2 for restricting the axial movement of the rotating shaft 2. By providing the limiting member 21, when the rotating shaft 2 axially moves, since the size of the limiting member 21 is larger than the through hole 121, it can play a role in restricting the rotating shaft 2 from detaching from the fixed bracket 1. The present disclosure does not limit the structure of the limiting member 21. For example, it may be a limiting ring, specifically a C-shaped structure with elasticity. When installing, an external force is applied to make its opening larger and the rotating shaft 2 is inserted. Then, when the external force is removed, the limiting ring can elastically reset to tightly hold the rotating shaft 2. Correspondingly, an annular groove 22 may be provided at the end of the rotating shaft 2, and the limiting ring may be installed in the annular groove 22.

[0055] It should be noted that, in some embodiments, a limiting member 21 may be provided at each end of the rotating shaft 2 respectively. In addition, in some other embodiments, one end of the rotating shaft 2 may be configured as a large-head section (the outer contour is larger than the through hole 121). In this case, only a limiting member 21 needs to be provided at one end of the rotating shaft 2.

[0056] Refer to Figures 8 - 13 , according to the second aspect of the present disclosure, a board card module is provided, including a board card 6, a board card bracket 7, and the aforementioned quick-release assembly. The fixed bracket 1 is fixed to the board card bracket 7, and the buckle 3 is used to press and fix the board card 6 to the board card bracket 7 or release it from the board card bracket 7. Since this board card module has all the beneficial effects of the above quick-release assembly, it will not be elaborated here. It should be explained that the board card 6 here refers to an expansion card configured in a board shape, such as a network adapter card, a RAID controller card, a high-speed memory card, a GPU card, etc.

[0057] In an embodiment of the present disclosure, the number of the board cards 6 can be multiple. Each fastening buckle 3 can act on multiple board cards 6 simultaneously or act on one board card 6 to clamp the board card 6 when the rotating shaft 2 is located at the locking position 41 and release the board card 6 when the rotating shaft 2 is located at the unlocking position 42. To facilitate the quick-release assembly to act on multiple board cards 6, in some embodiments, multiple board cards 6 can all be PCIe cards. It should be noted that PCIe (Peripheral Component Interconnect Express) is a bus standard for connecting high-speed components to the computer motherboard. The PCIe card is not limited to the foregoing GPU cards, etc. Any expansion card that follows the PCIe standard can be called a PCIe card. The board card strip (PCIe I / O Bracket) of the PCIe card has clearly defined detailed dimension specifications in the PCIe specification. It can be understood that PCIe is a specification and standard. As long as the card meets the PCIe specification, the size of its board card strip needs to meet the standard defined by PCIe. Therefore, when multiple board cards 6 are all PCIe cards, the structures and sizes of the board card strips 8 of the board cards 6 are the same. When using the quick-release assembly to cooperate with them, a unified fastening buckle 3 can be used, without the need to design different fastening buckles 3 for different board card strips, making the disassembly and assembly arrangement more convenient and cost-saving.

[0058] Referring to Figures 8 - 13 , in an embodiment of the present disclosure, the board card 6 can include a board card strip 8. When the rotating shaft 2 is located at the locking position 41, the rotation of the fastening buckle 3 is interfered to clamp the board card strip 8 to the board card bracket 7. Indirect clamping and locking of the board card 6 can be achieved by clamping the board card strip 8. In an embodiment of the present disclosure, the board card bracket 7 can be configured as an L-shaped structure including a vertical plate and a horizontal plate. The fixed bracket 1 is installed on the vertical plate, and when the rotating shaft 2 is at the locking position 41, the rotation of the fastening buckle 3 interferes with the horizontal plate, and the fastening buckle 3 clamps the board card strip 8 to the horizontal plate to limit the movement of the board card 6 in the direction perpendicular to the horizontal plate to achieve locking.

[0059] Referring to Figures 10 - 12, in an embodiment of the present disclosure, the board card strip 8 and the board card bracket 7 are at least partially stacked in the disassembly and assembly direction of the board card 6, and the buckle 3 can press and fix the board card strip 8 along the disassembly and assembly direction. In order to prevent the board card strip 8 from moving in a plane perpendicular to the first direction relative to the board card bracket 7, one of the board card strip 8 and the board card bracket 7 may be formed with a protruding structure 51 extending along the disassembly and assembly direction, and the other may be formed with an opening 52 that cooperates with the protruding structure 51 to limit the movement of the board card strip 8 relative to the board card bracket 7 in a plane perpendicular to the disassembly and assembly direction. By providing the protruding structure 51 and the opening 52, on the one hand, it can play a limiting role in a plane perpendicular to the disassembly and assembly direction, and on the other hand, it can also play a positioning role during installation. The present disclosure does not limit the specific structure and shape of the protruding structure 51 and the opening 52, and they can be adaptively designed according to the specific structures of the board card bracket 7 and the board card strip 8. It should be noted that the "disassembly and assembly direction" here refers to the direction of installing the board card 6 onto the board card bracket 7 or removing the board card 6 from the board card bracket 7. After installing it onto the board card bracket 7 along the disassembly and assembly direction, the buckle 3 can press and fix the board card 6 (actually the board card strip 7) along the disassembly direction to lock it to the board card bracket 7.

[0060] Referring to Figure 13 , in an embodiment of the present disclosure, the number of board cards 6 can be multiple, and the number of quick-release components is multiple.

[0061] According to the third aspect of the present disclosure, there is provided an electronic device including the foregoing board card module. Since this electronic device has all the beneficial effects of the foregoing board card module, they will not be elaborated here.

However, the present disclosure is not limited to the specific details in the above embodiments.

[0063] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0064] In addition, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
