[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202422081854.9, filed on August 26, 2024, entitled "Quick-release Components, Board Modules and Electronic Devices", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of quick-release component technology, specifically to a quick-release component, board module, and electronic device. Background Technology

[0004] In related technologies, bolts or screws are typically used to detachably attach one component to another. However, this method requires tools such as wrenches and screwdrivers during disassembly and assembly, making the process cumbersome and time-consuming. Furthermore, there is a risk of bolts or screws falling out and being lost during repeated disassembly and assembly, especially when the two components are electrical or precision mechanical parts; lost screws or bolts can easily pose a safety hazard. Summary of the Invention

[0005] The purpose of this disclosure is to provide a quick-release component, board module, and electronic device to at least partially solve the problems existing in the related art.

[0006] To achieve the above objectives, this disclosure provides a quick-release assembly, comprising: a bracket; a limiting member movably connected to the bracket along a first direction, wherein the limiting member has a locking position for locking a component to be installed and an unlocking position for unlocking the component to be installed; and a locking member for restricting the limiting member to the unlocking position.

[0007] Optionally, it further includes a first elastic member connected between the limiting member and the bracket, wherein when the limiting member is in the unlocked position, the first elastic member has an elastic force that drives the limiting member to move toward the locked position.

[0008] Optionally, the limiting member is provided with a first latch for securing the component to be installed.

[0009] Optionally, there are multiple first clips, which are arranged at intervals along the first direction, and each first clip is used independently to secure its corresponding component to be installed.

[0010] Optionally, one of the limiting member and the bracket has a first guide groove extending along the first direction, and the other of the limiting member and the bracket has a first guide post extending into the first guide groove.

[0011] Optionally, a first limiting member is sleeved on the free end of the first guide post to restrict the first guide post within the first guide groove.

[0012] Optionally, the locking member is movably connected to the bracket along the second direction. The locking member is provided with a second latch, and the limiting member is also provided with a third latch. When the limiting member needs to move from the locked position to the unlocked position, the locking member moves from the initial position to the avoidance position along the second direction. When the limiting member moves to the unlocked position, the locking member returns to the initial position and stops the third latch by the second latch.

[0013] Optionally, the second latch is formed with an inclined surface toward the limiting member, such that as the limiting member moves from the locked position to the unlocked position, the third latch presses against the inclined surface to push the lock from the initial position to the avoidance position along the second direction.

[0014] Optionally, it further includes a second elastic member connected between the lock and the bracket, wherein when the lock moves from the initial position toward the avoidance position along the second direction, the second elastic member deforms to have an elastic force that drives the lock to reset.

[0015] Optionally, one of the locking member and the bracket has a second guide groove extending along the second direction, and the other of the locking member and the bracket has a second guide post extending into the second guide groove.

[0016] Optionally, a second limiting member is fitted onto the free end of the second guide post to restrict the second guide post within the second guide groove.

[0017] Optionally, the bracket is provided with a protruding structure for positioning the component to be installed, so as to match the positioning hole of the component to be installed.

[0018] According to a second aspect of this disclosure, a board module is provided, including at least one board and the quick-release assembly described above, wherein the limiting member is used to lock or unlock the at least one board.

[0019] Optionally, the board is equipped with a connecting member, the connecting member having a fourth latch, and the limiting member is used to press and secure the fourth latch to lock the board.

[0020] Optionally, a mounting bracket is included, the support is mounted on the mounting bracket, and the limiting member is used to press the connecting member onto the support.

[0021] According to a third aspect of this disclosure, an electronic device is provided, including the aforementioned board module.

[0022] With the above technical solution, when it is necessary to install and lock the component to be installed, the limiting component can be moved to the unlocked position along the first direction, and the locking device can be used to keep the limiting component in the locked position. The component to be installed can then be installed in place, and the locking device can be controlled to unlock, allowing the limiting component to move to the locked position to lock and fix the component to be installed. When it is necessary to disassemble the component to be installed, the limiting component can be moved to the unlocked position along the first direction, and the locking device can be used to restrict the limiting component to the unlocked position, thus unlocking the component to be installed and completing the disassembly. This design eliminates the need for traditional screws and bolts, making the disassembly and assembly simple and quick without the need for tools, and avoiding the potential hazards caused by bolts or screws falling onto the component to be installed.

[0023] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0038] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0039] In this disclosure, unless otherwise stated, the directional terms "inner" and "outer" are used based on the structure of the relevant components themselves. For example, if the lock and the bracket have a second guide post extending "inner" into the second guide groove, it means that the second guide post extends into the receiving space of the first guide groove. The terms "first direction" and "second direction" can be specifically referred to as the arrow directions in Figure 1. They can be perpendicular to each other, or the included angle can be 80°, 110°, etc., wherein the first direction and the second direction respectively include reciprocating motion along the positive and negative directions.

[0040] In addition, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0041] Referring to Figures 1-11, this disclosure exemplarily illustrates a quick-release assembly 100, including a bracket 1, a limiting member 2 movably connected to the bracket 1 along a first direction, and a locking member 3. This disclosure does not limit how the limiting member 2 can be movably connected to the bracket 1 along the first direction; for example, it can be achieved using a first guide post and a first guide groove, as mentioned below. Furthermore, in some other embodiments, the two can also be achieved using a slider and a slide rail, which this disclosure does not limit. In the first direction, the limiting member 2 has a locking position for locking the component 400 to be installed and an unlocking position for unlocking the component 400 to be installed. The locking member 3 is used to restrict the limiting member 2 to the unlocking position. This disclosure does not limit the structure of the locking member 3 or how the locking member 3 restricts the limiting member 2 to the unlocking position; for details, please refer to the specific embodiments section below, which will not be repeated here.

[0042] It should be explained that "the component to be installed 400" here refers to all related components that can be locked and unlocked by the quick-release assembly 100. For example, it can be the circuit board mentioned below. In the locked position, the quick-release assembly 100 can lock and fix the circuit board to prevent it from moving out of the installation position; in the unlocked position, the quick-release assembly 100 can unlock and release the circuit board so that it can be disassembled without obstacles.

[0043] By using the above technical solution, when it is necessary to install and lock the component 400 to be installed, the limiting member 2 can be moved to the unlocked position along the first direction, and the locking member 3 can be used to keep the limiting member 2 in the locked position. The component 400 to be installed can then be installed in place. Then, the locking member 3 can be controlled to unlock, allowing the limiting member 2 to move to the locked position to lock and fix the component 400 to be installed. When it is necessary to disassemble the component 400 to be installed, the limiting member 2 can be moved to the unlocked position along the first direction, and the locking member 3 can be used to restrict the limiting member 2 to the unlocked position, thereby unlocking the component 400 to be installed and completing the disassembly. This design eliminates the need for traditional screws and bolts, making the disassembly and assembly simple and quick, without the need for tools, and avoiding the potential hazards caused by bolts or screws falling onto the component 400 to be installed.

[0044] Referring to Figures 5 and 6, in embodiments of this disclosure, the quick-release assembly 100 may further include a first elastic member 41 connected between the limiting member 2 and the bracket 1. When the limiting member 2 is in the unlocked position, the first elastic member 41 may have a spring force that drives the limiting member 2 toward the locked position. With this design, when the limiting member 2 is in the unlocked position and is restricted by the locking member 3, the first elastic member 41 deforms with a spring force. When the locking member 3 is unlocked, this spring force can drive the limiting member 2 to reset toward the locked position, thereby locking and fixing the component 400 to be installed without manual control of the reset, making operation convenient. Furthermore, after the reset, due to the action of the first elastic member 41, without applying external force to deform the first elastic member 41, it can keep the limiting member 2 in the locked position.

[0045] This disclosure does not limit the first elastic element 41, which can be a helical spring as shown in Figures 5 and 6, with both ends of the helical spring fixedly connected to the bracket 1 and the limiting member 2, respectively. Alternatively, in some other embodiments, the first elastic element 41 can also be a rubber band, a rubber column, etc.

[0046] Referring to Figures 1 and 2, in embodiments of this disclosure, the limiting member 2 may be provided with a first latch 51 for securing the member 400 to be installed. By providing the first latch 51, the member 400 to be installed can be secured by the first latch 51 when the limiting member 2 is in the locked position. In embodiments of this disclosure, the first latch 51 may be integrally formed with the limiting member 2.

[0047] Further, referring to Figures 1 and 2, in the embodiments of this disclosure, the number of first latches 51 can be multiple, and they are arranged sequentially at intervals along the first direction. Each first latch 51 can be independently used to clamp its corresponding component 400 to be installed. With this design, each first latch 51 corresponds to one component 400 to be installed, thereby enabling the simultaneous locking or unlocking of multiple components 400 to be installed when controlling the movement of one limiting member 2 along the first direction. This is convenient and quick, eliminating the need to control unlocking and locking separately for each component 400. It should be explained that, to avoid a first latch 51 being in an unlocked position relative to one component 400 but in a locked position relative to another, in the embodiments of this disclosure, the clamping points of multiple components 400 to be installed (e.g., the fourth latch mentioned below) can be arranged sequentially at intervals along the first direction. This allows the first latch 51 to be located between two adjacent clamping points when the limiting member 2 is in the unlocked position, thus avoiding clamping and locking at any clamping point.

[0048] To enable the limiting member 2 to reciprocate relative to the bracket 1 along a first direction, referring to Figure 6, in an embodiment of this disclosure, one of the limiting member 2 and the bracket 1 may have a first guide groove 61 extending along the first direction, and the other of the limiting member 2 and the bracket 1 may have a first guide post 62 extending into the first guide groove 61. The first guide post 62 can move within the first guide groove 61 along the first direction, thereby enabling the limiting member 2 to move relative to the bracket 1 along the first direction. In an embodiment of this disclosure, the number of first guide posts 62 and first guide grooves 61 may be two, three, or other similar. The first guide post 62 may be a rivet riveted to the bracket 1, or it may be a protrusion formed on the limiting member 2.

[0049] Furthermore, in the embodiments of this disclosure, the free end of the first guide post 62 may be fitted with a first limiting member 63 to restrict the first guide post 62 within the first guide groove 61. Specifically, referring to FIG6, the outer contour of the first limiting member 63 may be larger than the first guide groove 61, thereby preventing the first guide post 62 from detaching from the first guide groove 61, thus achieving a dynamic connection between the limiting member 2 and the bracket 1, preventing them from separating from each other. The first limiting member 63 may be a metal ring, a rubber ring, etc., and can be specifically designed according to the material of the first guide post 62. It should be explained that when the first guide post 62 is formed on the limiting member 2, the "free end" here refers to the end of the first guide post 62 away from the limiting member 2; when the first guide post 62 is formed on the bracket 1, the "free end" here refers to the end of the first guide post 62 away from the bracket 1.

[0050] Referring to Figures 1-7, in the embodiments of this disclosure, the locking member 3 is movably connected to the bracket 1 along the second direction. The locking member 3 may be provided with a second latch 52, and the limiting member 2 may also be provided with a third latch 53. Specifically, when the limiting member 2 needs to move from the locked position to the unlocked position, the locking member 3 can move from its initial position to a clearance position along the second direction; when the limiting member 2 moves to the unlocked position, the locking member 3 can return to its initial position and stop the third latch 53 through the second latch 52. Here, in the initial position, the second latch 52 and the third latch 53 can form a locking relationship along the first direction; in the clearance position, the second latch 52 and the third latch 53 clearance each other in the first direction, that is, when the limiting member 2 moves along the first direction, the second latch 52 avoids the movement trajectory of the third latch 53. In the embodiments of this disclosure, the locking member 3 can be controlled to move to the avoidance position before the limiting member 2 starts to operate, or the locking member 3 can be controlled to move to the avoidance position during the process of the limiting member 2 moving towards the unlocking position. This disclosure does not limit this, as long as the locking member 3 can avoid the limiting member 2 during the process of the limiting member 2 moving towards the unlocking position, and can reset and lock the limiting member 2 when the limiting member 2 moves to the unlocking position.

[0051] Furthermore, in the embodiments of this disclosure, the second latch 52 may be formed with an inclined surface 521 facing the limiting member 2, such that during the process of the limiting member 2 moving from the locked position to the unlocked position, the third latch 53 can press the inclined surface 521 to push the lock member 3 from the initial position to the avoidance position along the second direction. Through the "inclined surface" design, the lock member 3 can automatically move from the initial position to the avoidance position during the process of the limiting member 2 moving from the locked position to the unlocked position, making the operation more convenient and faster. In addition, in some other embodiments, the inclined surface design of the second latch 52 may be omitted. In this case, the lock member 3 can be manually controlled to move from the initial external position along the second direction so that the limiting member 2 can move to the unlocked position, and then the lock member 3 can reset to a position where the second latch 52 and the third latch 53 can lock together. In the embodiments of this disclosure, the second latch 52 may be integrally formed with the lock member 3, and the third latch 53 may be integrally formed with the limiting member 2. This disclosure does not limit the formation method of the second latch 52 and the third latch 53.

[0052] Referring to Figures 3 and 5-6, in embodiments of this disclosure, the quick-release assembly 100 may further include a second elastic member 42 connected between the locking member 3 and the bracket 1. When the locking member 3 moves from its initial position toward the clearance position along a second direction, the second elastic member 42 can deform to have a spring force that drives the locking member 3 to reset. With this design, when the limiting member 2 moves to the unlocked position, the third latch 53 disengages from the inclined surface 521, and the locking member 3 can reset to its initial position under the deformation spring force of the second elastic member 42, causing the second latch 52 and the third latch 53 to lock together.

[0053] This disclosure does not limit the first elastic element 41, which can be a helical spring as shown in Figures 5 and 6, with both ends of the helical spring fixedly connected to the bracket 1 and the limiting member 2, respectively. Alternatively, in some other embodiments, the first elastic element 41 can also be a rubber band, a rubber column, etc.

[0054] To allow the locking member 3 to move relative to the bracket 1 in a second direction, referring to FIG6, in an embodiment of this disclosure, one of the locking member 3 and the bracket 1 may have a second guide groove 64 extending in the second direction, and the other of the locking member 3 and the bracket 1 may have a second guide post 65 extending into the second guide groove 64. In an embodiment of this disclosure, the number of second guide posts 65 and second guide grooves 64 may be two, three, or other similar. The second guide post 65 may be a rivet riveted to the bracket 1, or it may be a protrusion formed on the locking member 3.

[0055] Referring to Figures 3 and 6, in the embodiments of this disclosure, the free end of the second guide post 65 may be fitted with a second limiting member 66 to restrict the second guide post 65 within the second guide groove 64. Specifically, referring to Figure 6, the outer contour of the second limiting member 66 may be larger than the second guide groove 64, thereby preventing the second guide post 65 from detaching from the second guide groove 64, thus achieving a dynamic connection between the locking member 3 and the bracket 1, preventing them from separating from each other. The second limiting member 66 may be a metal ring, a rubber ring, etc., and can be specifically designed according to the material of the second guide post 65. It should be explained that when the second guide post 65 is formed on the locking member 3, the "free end" here refers to the end of the second guide post 65 away from the locking member 3; when the second guide post 65 is formed on the bracket 1, the "free end" here refers to the end of the second guide post 65 away from the bracket 1.

[0056] Referring to Figures 1, 4, and 8, in embodiments of this disclosure, the bracket 1 may be provided with a protruding structure 11 for positioning the component 400 to be installed, which matches the positioning hole 410 of the component 400. The protruding structure 11 and the positioning hole 410 cooperate to provide positioning during installation of the component 400, and also provide radial positioning of the component 400 within the positioning hole 410. For example, when the component 400 to be installed is a board (described below), the positioning hole may be formed in the connecting member 8.

[0057] Referring to Figures 8-11, according to a second aspect of this disclosure, a board module 200 is provided, including at least one board 7 and the aforementioned quick-release assembly 100, with a limiting member 2 for locking or unlocking the board 7. Since this board module 200 possesses all the beneficial effects of the aforementioned quick-release assembly 100, further details are omitted here. It should be noted that the board 7 here refers to an expansion card constructed in a board shape, such as a network adapter card, RAID controller card, high-speed storage card, GPU card, etc.

[0058] In the embodiments of this disclosure, the number of circuit boards 7 can be multiple, and each limiting member 2 has multiple first latches 51, so that multiple circuit boards 7 can be acted on simultaneously, so that multiple circuit boards 7 can be pressed and secured simultaneously when the limiting member 2 is in the locked position, and multiple circuit boards 7 can be released simultaneously when the limiting member 2 is in the unlocked position.

[0059] In the embodiments of this disclosure, the board 7 may be equipped with a connecting member 8, which may have a fourth latch 54. The limiting member 2 is used to press and secure the fourth latch 54 to lock the board 7. Specifically, the first latch 51 mentioned above can be pressed and secured to the fourth latch 54. By pressing and securing the connecting member 8, the board 7 can be indirectly pressed and locked, avoiding the risk of damage that may occur from directly pressing and securing the board 7.

[0060] Referring to Figure 8, in an embodiment of this disclosure, the board module 200 may include a mounting frame 9, a bracket 1 may be mounted on the mounting frame 9, and a limiting member 2 is used to press the connecting member 8 onto the bracket 1, thereby indirectly pressing the board 7 onto the mounting frame 9. Specifically, in the embodiment shown in Figure 8, the mounting frame 9 includes two mutually spaced and parallel mounting plates, and multiple boards 7 may be mounted between the two mounting plates (mounted from top to bottom). The bracket 1 may be mounted between the two mounting plates, and the limiting member 2 can lock the board 7 by pressing it onto the bracket 1 in the vertical direction.

[0061] According to a third aspect of this disclosure, an electronic device 300 is provided, including the aforementioned board module 200. Since the electronic device 300 has all the beneficial effects of the aforementioned board module 200, it will not be described in detail here.

[0062] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0063] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0064] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
