Detailed description of the specific implementation

[0036] The following will describe in detail the specific implementation of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only for the purpose of illustrating and explaining the present disclosure and is 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 second guiding post of the locking member and the other of the brackets extending into the "inside" of the second guiding groove means that the second guiding post extends into the accommodation space inside the first guiding groove. The specific "first direction" and "second direction" can be seen in Figure 1 the arrow directions in [reference], the two can be perpendicular to each other, or the included angle between the two can also be 80°, 110°, etc. Among them, the first direction and the second direction respectively include reciprocating movements along the positive direction and the negative direction.

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

[0039] Reference Figures 1-11 The present disclosure exemplarily shows a quick-release assembly, including a bracket 1, a limiting member 2 movably connected to the bracket 1 along a first direction, and a lock 3. The present 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 through the first guide column and the first guide groove mentioned below. In addition, in some other embodiments, the two can also be achieved through the cooperation of a slider and a slideway, and the present disclosure does not limit this. In the first direction, the limiting member 2 has a locking position for locking the component to be installed, and an unlocking position for unlocking the component to be installed, and the lock 3 is used to limit the limiting member 2 to the unlocking position. The present disclosure does not limit the structure of the lock 3 and how the lock 3 can limit the limiting member 2 to the unlocking position. For details, please refer to the specific embodiment part below, and no repeated introduction is made here.

[0040] It should be explained that the "components to be installed" here refer to all related components that can be locked and unlocked by quick-release components, such as the board mentioned below. When in the locked position, the quick-release component can lock and fix the board to prevent it from moving out of the installation position; in the unlocked position, the quick-release component can unlock and release the board so that it can be removed without obstacles.

[0041] By using the above technical solution, when it is necessary to install and lock the component to be installed, the limiting member 2 can be moved to the unlocked position along the first direction, and the limiting member 2 can be kept in the locked position by the lock 3, the component to be installed can be installed in place, and then the lock 3 can be controlled to unlock so that the limiting member 2 moves 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 member 2 can be controlled to move to the unlocked position along the first direction, and the limiting member 2 can be restricted to the unlocked position by the lock 3, so that the component to be installed can be unlocked and disassembled. With such a design, traditional screws and bolts are eliminated, and the disassembly and assembly are simple and quick, without the need for tools, and the bolts or screws can be prevented from falling and causing hidden dangers to the component to be installed.

[0042] Reference Figure 5 and Figure 6, in an embodiment of the present disclosure, the quick-release assembly may further include a first elastic member 41 connected between the limiting member 2 and the bracket 1. Wherein, when the limiting member 2 is in the unlocking position, the first elastic member 41 may have an elastic force that drives the limiting member 2 to move towards the locking position. With such a design, when the limiting member 2 is in the unlocking position and restricted by the locking member 3, the first elastic member 41 deforms and has an elastic force. When the locking member 3 is controlled to be unlocked, this elastic force can drive the limiting member 2 to reset towards the locking position, thereby locking and fixing the member to be installed, without manual control of the reset, and the operation is convenient. And after its reset, due to the action of the first elastic member 41, when no external force is applied to deform the first elastic member 41, it can keep the limiting member 2 in the locking position.

[0043] The present disclosure does not limit the first elastic member 41, and it may be Figure 5 and Figure 6 the helical spring shown in, and both ends of the helical spring are fixedly connected to the bracket 1 and the limiting member 2 respectively. Or, in some other embodiments, the first elastic member 41 may also be a rubber band, a rubber column, etc.

[0044] Referring to Figure 1 and Figure 2 , in an embodiment of the present disclosure, the limiting member 2 may be provided with a first lug 51 for pressing and fixing the member to be installed. By providing the first lug 51, when the limiting member 2 is in the locking position, the first lug 51 can press and fix the member to be installed. In an embodiment of the present disclosure, the first lug 51 may be integrally formed with the limiting member 2.

[0045] Further, referring to Figure 1 and Figure 2 , in an embodiment of the present disclosure, the number of the first lugs 51 may be multiple, and they are arranged at intervals in sequence along the first direction. Each first lug 51 can independently be used to press and fix the corresponding member to be installed. With such a design, each first lug 51 corresponds to a member to be installed, so that when controlling the movement of a limiting member 2 along the first direction, the locking or unlocking of multiple members to be installed can be achieved simultaneously, and the operation is convenient and fast, without separately controlling the unlocking and locking for each member to be installed. It should be noted that, in order to prevent a first lug 51 from being in the unlocking position relative to one member to be installed while constituting the locking position relative to another member to be installed, in an embodiment of the present disclosure, the pressing points (such as the fourth lugs mentioned below) of multiple members to be installed for being pressed and fixed by the first lugs 51 may be arranged at intervals in sequence along the first direction, so that when the limiting member 2 is in the unlocking position, the first lug 51 can be located between two adjacent pressing points, thereby preventing the pressing and locking of any pressing point.

[0046] To enable the limiting member 2 to reciprocate relative to the bracket 1 in the first direction, refer to Figure 6 , in the embodiments of the present disclosure, one of the limiting member 2 and the bracket 1 may have a first guiding groove 61 extending in the first direction, and the other of the limiting member 2 and the bracket 1 may have a first guiding post 62 extending into the first guiding groove 61. The first guiding post 62 can move in the first guiding groove 61 in the first direction so as to realize the movement of the limiting member 2 relative to the bracket 1 in the first direction. In the embodiments of the present disclosure, the number of the first guiding posts 62 and the first guiding grooves 61 may be two, three, etc. Among them, the first guiding post 62 may be a rivet riveted to the bracket 1, or may also be a convex post formed on the limiting member 2.

[0047] Further, in the embodiments of the present disclosure, a first limiting member 63 may be sleeved on the free end of the first guiding post 62 to limit the first guiding post 62 in the first guiding groove 61. Specifically, refer to Figure 6 , the outer contour of the first limiting member 63 may be larger than that of the first guiding groove 61, so that the first guiding post 62 cannot break away from the first guiding groove 61, that is, the dynamic connection between the limiting member 2 and the bracket 1 is realized, and the two cannot separate 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 guiding post 62. It should be noted that when the first guiding post 62 is formed on the limiting member 2, the "free end" here refers to the end of the first guiding post 62 away from the limiting member 2; when the first guiding post 62 is formed on the bracket 1, the "free end" here refers to the end of the first guiding post 62 away from the bracket 1.

[0048] Refer to Figures 1-7In the embodiment of the present disclosure, the lock 3 can be movably connected to the bracket 1 along the second direction, the lock 3 can be provided with a second latch 52, and the limiting member 2 can also be provided with a third latch 53. When the limiting member 2 needs to move from the locked position to the unlocked position, the lock 3 can move from the initial position to the avoidance position along the second direction; when the limiting member 2 moves to the unlocked position, the lock 3 can be reset to the initial position and stop the third latch 53 through the second latch 52. Here, at the initial position, the second latch 52 and the third latch 53 can be locked along the first direction; at the avoidance position, the second latch 52 and the third latch 53 avoid 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 the present disclosure, the lock element 3 can be controlled to move to the avoidance position before the limiting member 2 starts to operate, or the lock element 3 can be controlled to move to the avoidance position when the limiting member 2 moves toward the unlocking position. The present disclosure does not impose any restrictions on this, as long as the lock element 3 can avoid the limiting member 2 when the limiting member 2 moves toward the unlocking position, and can reset the limiting member 2 when the limiting member 2 moves to the unlocking position.

[0049] Further, in the embodiment of the present disclosure, the second ear 52 may be formed with an inclined surface 521 facing the limiting member 2, so that in the process of the limiting member 2 moving from the locked position to the unlocked position, the third ear 53 may squeeze the inclined surface 521 to push the lock 3 to move from the initial position to the escape position along the second direction. Through the "inclined surface" design, the lock 3 can automatically move from the initial position to the escape position in the process of the limiting member 2 moving from the locked position to the unlocked position, and the operation is more convenient and quick. In addition, in some other embodiments, the second ear 52 may cancel the inclined surface design. In this case, the lock 3 may 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 3 is reset to the second ear 52 and can be locked with the third ear 53. In the embodiment of the present disclosure, the second ear 52 can be integrally formed with the lock 3, and the third ear 53 can be integrally formed with the limiting member 2. The present disclosure does not limit the formation method of the second ear 52 and the third ear 53.

[0050] Reference Figure 3 , Figures 5-6 In the embodiment of the present disclosure, the quick release assembly may further include a second elastic member 42 connected between the lock member 3 and the bracket 1. When the lock member 3 moves from the initial position along the second direction toward the avoidance position, the second elastic member 42 may be deformed to have an elastic force to drive the lock member 3 to reset. With such a design, when the limiting member 2 moves to the unlocking position, the third latch 53 is separated from the inclined surface 521, and the lock member 3 can be reset to the initial position under the deformation elastic force of the second elastic member 42, so that the second latch 52 and the third latch 53 are locked.

[0051] The present disclosure does not limit the first elastic member 41, which may be Figure 5 and Figure 6 The coil spring shown in the figure has two ends fixedly connected to the bracket 1 and the limiting member 2. Alternatively, in some other embodiments, the first elastic member 41 may also be a rubber band, a rubber column, etc.

[0052] In order for the locking member 3 to move relative to the bracket 1 along the second direction, refer to Figure 6 In the embodiment of the present disclosure, one of the lock 3 and the bracket 1 may have a second guide groove 64 extending along the second direction, and the other of the lock 3 and the bracket 1 may have a second guide column 65 extending into the second guide groove 64. In the embodiment of the present disclosure, the number of the second guide column 65 and the second guide groove 64 may be two, three, etc. The second guide column 65 may be a rivet riveted to the bracket 1, or may be a convex column formed on the lock 3.

[0053] Reference Figure 3 and Figure 6 In the embodiment of the present disclosure, the free end of the second guide column 65 may be sleeved with a second stopper 66 to limit the second guide column 65 in the second guide groove 64. Figure 6 , the outer contour of the second limiter 66 can be larger than the second guide groove 64, so that the second guide column 65 cannot be separated from the second guide groove 64, that is, the dynamic connection between the lock 3 and the bracket 1 is realized, so that the two cannot be separated from each other. The second limiter 66 can be a metal ring, a rubber ring, etc., and can be specifically designed according to the material adaptability of the second guide column 65. It should be explained that when the second guide column 65 is formed on the lock 3, the "free end" here refers to the end of the second guide column 65 away from the lock 3; when the second guide column 65 is formed on the bracket 1, the "free end" here refers to the end of the second guide column 65 away from the bracket 1.

[0054] Reference Figure 1 and Figure 4 In the embodiment of the present disclosure, the bracket 1 may be provided with a protruding structure 11 for positioning the component to be installed, so as to match the positioning hole of the component to be installed. The protruding structure 11 and the positioning hole can play a positioning role when the component to be installed is installed, and can play a positioning role for the component to be installed in the radial direction of the positioning hole. For example, when the component to be installed is a board mentioned below, the positioning hole can be opened in the connecting member 8.

[0055] Reference Figures 8-11, according to the second aspect of the present disclosure, there is provided a board module, including at least one board 7 and the aforementioned quick-release component, and the limiting member 2 is used to lock or unlock the board 7. Since this board module has all the beneficial effects of the above quick-release component, it will not be elaborated here. It should be explained that the board 7 here refers to an expansion card configured in a plate shape, such as a network adapter card, a RAID controller card, a high-speed memory card, a GPU card, etc.

[0056] In an embodiment of the present disclosure, the number of boards 7 can be multiple, and each limiting member 2 has multiple first lugs 51, so as to act on multiple boards 7 simultaneously, so as to simultaneously press and fix multiple boards 7 when the limiting member 2 is in the locking position, and simultaneously release multiple boards 7 when the limiting member 2 is in the unlocking position.

[0057] In an embodiment of the present disclosure, the board 7 can be installed with a connecting member 8, and the connecting member 8 can be formed with a fourth lug 54, and the limiting member 2 is used to press and fix the fourth lug 54 to lock the board 7. Specifically, the first lug 51 mentioned above can be pressed and fixed on the fourth lug 54. By pressing and fixing the connecting member 8, the indirect pressing and locking of the board 7 can be realized, avoiding the risk of being easily damaged by directly pressing and fixing the board 7.

[0058] Referring to Figure 8 , in an embodiment of the present disclosure, the board module can include a mounting bracket 9, the bracket 1 can be mounted on the mounting bracket 9, and the limiting member 2 is used to press and fix the connecting member 8 on the bracket 1, so as to indirectly press and fix the board 7 on the mounting bracket 9.
