Description

Floating components, fasteners, brackets, and server systems Technical Field

[0001] This disclosure relates to the field of server systems, and more particularly to a floating component, fastening device, bracket, and server system. Background Technology

[0002] Solid-state drives (SSDs) are essential hardware components in server system chassis. In traditional server system chassis, the most common SSD type is the U.2 interface (specification name: SFF-8639 standard). The U.2 interface is an SSD interface standard specifically designed for enterprise-level storage. It provides a PCIe (Peripheral Component Interconnect Express) connection from the computer to the SSD and is compatible with SAS (Serial Attached SCSI) and SATA (Serial ATA) interfaces, thus meeting the diverse needs of enterprise-level storage.

[0003] However, with the growth of data volume, the demands on server storage capacity are increasing, and existing U.2 hard drives are struggling to evolve to meet these requirements. Therefore, EDSFF (Enterprise & Data Center SSD Form Factor), a solid-state drive specification defined for enterprise and data center use, emerged. EDSFF defines a series of dynamic hard drive form factors, offering advantages over U.2 hard drives in terms of capacity, scalability, performance, maintainability, manageability, heat dissipation, and power management. In practical applications, a dedicated hard drive bay corresponding to the drive size is installed inside the chassis for installing SSDs. Because both U.2 and EDSFF drive sizes are widely used, ordinary bays cannot simultaneously accommodate the installation of hard drives of different sizes. Summary of the Invention

[0004] This disclosure provides a floating component, a fastening device, a bracket, and a server system to address the shortcomings of related technologies, such as the inability of brackets to simultaneously accommodate the installation of hard drives of different sizes.

[0005] In a first aspect, this disclosure provides a floating assembly for securing an object to a mounting base in conjunction with fasteners. The floating assembly includes a fixed member and a movable member. The fixed member is used to secure the object to the mounting base and includes a side wall and a fixed side and a floating side disposed opposite each other along the thickness direction. The side wall forms a receiving cavity. The movable member is slidably disposed in the receiving cavity such that it protrudes from the fixed side towards the floating side. The movable member includes an abutment surface and a mounting hole. The abutment surface abuts against the object to be secured, and the fixed side is farther from the abutment surface than the floating side. The mounting hole communicates the abutment surface with the receiving cavity and serves to limit the fastener.

[0006] The floating component is used to switch between a retracted state and a protruding state. When the floating component is in the retracted state, the minimum distance from the abutment surface to the fixed side is a first distance. When the floating component is in the protruding state, the abutment surface protrudes from the floating side, and the minimum distance from the abutment surface to the fixed side is a second distance. The second distance is greater than the first distance.

When the floating component is in the retracted state, the blocking part simultaneously engages with the first groove and the second groove.

[0018] Optionally, the sidewall includes a first sidewall and a second sidewall. The curvature of the first sidewall is different from the curvature of the second sidewall.

[0019] Secondly, this disclosure also provides a fastening device, including a fastener and a floating component as described in the first aspect. The fastener is detachably disposed in the mounting hole, passes through the mounting hole in a direction from the fixed side to the floating side, and is used to secure the object to be secured.

[0020] Optionally, the movable component includes a mounting groove. The mounting groove communicates with both the receiving cavity and the mounting hole. The mounting groove includes a guide section and a mounting section. The guide section is positioned close to the fixed side. The inner diameter of the guide section is smaller than the inner diameter of the mounting section, forming a third limiting platform between the guide section and the mounting section.

[0021] In this configuration, one end of the fastener is engaged with the mounting section, and the other end passes through the mounting hole and extends in a direction from the fixed side to the floating side. Alternatively, one end of the fastener is engaged with the third limiting platform, and the other end passes through the mounting hole and extends in a direction from the fixed side to the floating side.

[0022] Thirdly, this disclosure also provides a bracket, including a frame, an installation space enclosed by the frame, and a floating component as described in the first aspect. The floating component is disposed on the frame.

[0027] Optionally, the mounting bracket includes a recessed groove and a through hole. The recessed groove is formed on the side of the mounting bracket facing the mounting space. The through hole is disposed in the recessed groove and connects both sides of the mounting bracket along its thickness direction.

[0028] Optionally, the fastener further includes a mounting portion. The mounting portion is connected to one end of the side wall near the floating side.

[0031] Optionally, the shortest distance between the light guide groove and the sinking groove is greater than or equal to 1 mm and less than or equal to 3 mm.

[0032] Fourthly, this disclosure also provides a server system including a hard disk and a bracket as described in the third aspect. The hard disk is disposed in the mounting space. The abutting surface is attached to the hard disk.

[0033] Optionally, the server system further includes a fastener. One end of the fastener is engaged with the movable component, and the other end passes through the mounting hole and is connected to the hard drive.

[0034] Optionally, when the width of the hard disk is equal to the width of the installation space, the end of the movable member away from the fixed side is flush with the floating side of the fixed member. When the width of the hard disk is less than the width of the installation space, the movable member protrudes from the fixed side toward the floating side, and the abutting surface abuts against the side surface of the hard disk.

[0035] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: As can be seen from the above embodiments, the floating component of this disclosure, through the interconnected accommodating cavity and mounting hole, allows fasteners to pass through the entire floating component and connect to the object to be fixed. Furthermore, during the process of fixing the object, the floating component can switch arbitrarily between a retracted state and a protruding state through the cooperative arrangement of the fixing and moving parts. When the size of the object to be fixed is relatively small compared to the frame, the floating component can switch to a protruding state so that the abutting surface abuts against the object; while when the size of the object to be fixed is comparable to the size of the frame, the floating component can switch to a retracted state so that the object can be smoothly installed into the frame, while also ensuring that the abutting surface abuts against the object, thereby ensuring the stability and safety of the object after installation. In addition, the floating component has a simple, small, and compact structure, is easy to manufacture and install, and will not significantly increase the frame volume when applied to a frame. Therefore, this floating component has high convenience, practicality, and a wide range of applications in both production and application.

Detailed Implementation

[0048] The technical solutions in the embodiments (or "implementations") of this disclosure will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0049] If this disclosure uses terms relating to directional indications or positional relationships (e.g., up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, terms such as "first" and "second" in this disclosure are used only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0050] In a first aspect, this disclosure provides a floating assembly 1 for securing an object to a frame 21 with fasteners. Referring to FIG. 1, the floating assembly 1 includes a fixing member 11 and a movable member 12. The fixing member 11 is used to fix the object to the frame 21 and includes a side wall 111 and a fixed side 112 and a floating side 113 disposed opposite each other along the thickness direction. The side wall 111 forms a receiving cavity 114. Referring to FIGS. 1 and 2, the movable member 12 is slidably disposed in the receiving cavity 114 such that the movable member 12 protrudes from the fixed side 112 in a direction toward the floating side 113. Referring to FIG. 3, the movable member 12 includes an abutment surface 121 and a mounting hole 122. The abutment surface 121 abuts against the object to be secured, and the fixed side 112 is farther from the abutment surface 121 than the floating side 113. The mounting hole 122 communicates the abutment surface 121 with the receiving cavity 114 and serves to limit the fastener.

[0051] As can be seen from Figures 1 and 2, the floating component 1 is used to switch between a retracted state and a protruding state. When the floating component 1 is in the retracted state, the minimum distance from the contact surface 121 to the fixed side 112 is a first distance. When the floating component 1 is in the protruding state, the contact surface 121 protrudes from the floating side 113, and the minimum distance from the contact surface 121 to the fixed side 112 is a second distance. The second distance is greater than the first distance.

[0052] As can be seen, the floating component 1 of this disclosure, through the interconnected receiving cavity 114 and mounting hole 122, allows fasteners to pass through the entire floating component 1 and connect to the object to be fixed. Furthermore, during the process of fixing the object, the cooperation between the fixing member 11 and the movable member 12 allows the floating component 1 to switch arbitrarily between a retracted state and a protruding state. When the size of the object to be fixed is smaller than the frame 21, the floating component 1 can switch to the protruding state so that the abutment surface 121 abuts against the object; while when the size of the object to be fixed is comparable to the size of the frame 21, the floating component 1 can switch to the retracted state so that the object to be fixed can be smoothly installed into the frame 21, while ensuring that the abutment surface 121 abuts against the object, thereby ensuring the stability and safety of the object after installation. Moreover, as can be seen from the accompanying drawings, the floating component 1 has a simple, small, and compact structure, is easy to manufacture and install, and will not significantly increase the volume of the frame 21 when applied to it. It is evident that the floating component 1 possesses high convenience, practicality, and a wide range of applications in both production and application.

[0053] Secondly, this disclosure also provides a fastening device (not shown in the figures), including a fastener and a floating component 1 as described in the first aspect. The fastener is detachably disposed in a mounting hole 122, passes through the mounting hole 122 in a direction from the fixed side 112 to the floating side 113 (i.e., the opposite direction of the third direction Z in Figure 2), and is used to fasten the object to be fastened.

[0054] As can be seen, the fastening device connects to the object to be fixed by inserting the fastener into the floating component 1 and passing it through the mounting hole 122. This fastening method is simple, effective, and easy to operate. Through the connection between the fastener and the object to be fixed, the floating component 1 can switch between the protruding state and the retracted state at will, so as to ensure that the contact surface 121 abuts against the object to be fixed. This effectively improves the stability of the connection between the fastening device and the object to be fixed, and also ensures the convenience and practicality of the fastening device in use.

[0055] It should be noted that in the embodiments disclosed in this disclosure, screws are used as fasteners. The screws are inserted into the floating component 1, with the nut secured within the floating component 1, and the screw shaft passes through the mounting hole 122 and is screwed onto the object to be fixed. This connection method is common in practical applications and allows adjustment of the protrusion distance of the floating component 1 during the screwing process, thereby ensuring balanced, uniform, and stable force on the object to be fixed. Of course, in other optional embodiments, the fastening device can also use other connection methods to attach the abutment surface 121 of the floating component 1 to the object to be fixed. For example, an adhesive element can be provided on the abutment surface 121 for fixation by adhesion; or a magnetic element can be provided within the floating component 1 for fixation by magnetic attraction. Therefore, this disclosure does not limit this approach.

[0056] Thirdly, as shown in Figures 5 to 7, this disclosure also provides a bracket 2, including a frame 21, an installation space 22 enclosed by the frame 21, and a floating component 1 as described in the first aspect. The floating component 1 is disposed on the frame 21. The floating side 113 is disposed towards the installation space 22, such that the fixed side 112 communicates with the installation space 22 through a mounting hole 122.

[0057] In actual use, the operator places the object to be fixed into the installation space 22 and connects it to the object by fasteners passing through the installation hole 122. During the connection process, the protrusion distance of the movable part 12 is adjusted to ensure that the contact surface 121 can be attached to the object to be fixed, thereby ensuring the stability and safety of the bracket 2 after fixing the object to be fixed, as well as the convenience of the fixing process.

[0058] Fourthly, as shown in Figures 8 and 9, this disclosure also provides a server system including a hard disk 3 and a bracket 2 as described in the third aspect. The hard disk 3 is disposed in an installation space 22. An abutment surface 121 is attached to the hard disk 3.

[0059] It should be noted that in practical applications, the object to be fixed mentioned above can be any component that needs to be fixed by the bracket 2, such as a processor, sensor, display adapter, RAM, etc., and this disclosure does not impose any restrictions on it. However, in the embodiments disclosed in this disclosure, for the convenience of explaining the structure, function, and installation method of the bracket 2 and the floating component 1, a hard disk 3 is used as an example as the object to be fixed.

[0060] Referring to the accompanying drawings, when the size of the hard drive 3 is relatively small compared to the installation space 22, directly connecting the hard drive 3 through the frame 21 with fasteners would inevitably cause the frame 21 to deform, thereby damaging the structure of the bracket 2. Simultaneously, the bending deformation of the frame 21 would also cause a change in the orientation of its screw holes, thus affecting the connection between the fasteners and the hard drive 3. However, the bracket 2 provided in this disclosure is equipped with a floating component 1. When the size of the hard drive 3 is relatively small compared to the installation space 22, the fasteners, during the process of fixing the hard drive 3, will cause the movable component 12 to slide, so that the contact surface 121 is attached to the side of the hard drive 3. This transfers the fixing point of the fasteners from the frame 21 to the movable component 12, avoiding the deformation of the frame 21 during the fixing process due to the gap between the frame 21 and the hard drive 3. This effectively ensures the stability, safety, and fixing effect of the bracket 2 on the hard drive 3.

[0061] Referring to Figures 1 and 2, in an optional embodiment, the movable member 12 includes a locking portion 123 and a connecting portion 124. The connecting portion 124 is disposed in the receiving cavity 114 and is sleeved on the locking portion 123. An abutment surface 121 is disposed at the end of the locking portion 123 away from the fixed side 112. When the floating component 1 is in the protruding state, the abutment surface 121 is located outside the end of the connecting portion 124 away from the fixed side 112.

[0062] In practical applications, due to the limited internal space of the server system and the compact arrangement of components, the size of the bracket 2 is also limited. For example, the thickness of the frame 21 is relatively small, which severely limits the space for the floating component 1. The floating component 1 of this disclosure, however, separates the movable part 12 into a connecting part 124 and a locking part 123 that interlock. In the retracted state, both the connecting part 124 and the locking part 123 are housed within the receiving cavity 114, preventing any protrusion. In the protruding state, the connecting part 124 protrudes from the fixing part 11, while the locking part 123 protrudes from the connecting part 124. This arrangement effectively increases the stroke of the floating component 1 within the limited thickness of the frame 21, allowing the frame 21 using this floating component 1 to accommodate objects with greater size differences, thereby effectively improving the applicability of the frame 21 and the floating component 1.

[0063] Of course, in the embodiments disclosed in this disclosure, factors such as the thickness, width, length, rigidity of the frame 21 and the usage scenario are comprehensively considered, and the floating component 1 is configured as three layers: a fixing part 11, a connecting part 124, and a locking part 123. In other embodiments, the configuration can be adjusted according to the actual application scenario, the specifications of the frame 21, and the specific needs of the user. For example, when the size of the bracket 2 is similar to or only slightly different from the size of the object to be fixed, the floating component 1 does not need to have a large stroke. Therefore, only the fixing part 11 and a single layer of movable part 12 can be provided, thereby reducing the overall size of the floating component 1. Similarly, if the size of the bracket 2 differs significantly from the size of the object to be fixed, the floating component 1 needs to have a large stroke. In this case, more layers of connecting parts 124 can be added based on the scheme disclosed in this disclosure to meet the installation requirements of the bracket 2. Therefore, this disclosure does not impose any limitations on this.

[0064] In an optional embodiment, as shown in FIG1, when the floating component 1 is in the retracted state, the abutment surface 121 is located in the end of the adapter 124 away from the fixed side 112, and the end of the adapter 124 away from the fixed side 112 is located in the receiving cavity 114.

[0065] As shown in the figure, in the retracted state, the contact surface 121 is located within the end of the adapter 124 away from the fixed side 112, while the end of the adapter 124 away from the fixed side 112 is located within the receiving cavity 114. In other words, the locking part 123 retracts into the adapter 124, and the adapter 124 retracts into the receiving cavity 114 of the fixing member 11, meaning that the movable member 12 is not exposed in the receiving cavity 114. Therefore, in the retracted state, the floating assembly 1 of this disclosure can retract the movable part into the receiving cavity 114, thereby effectively limiting its overall thickness and avoiding situations where the floating assembly 1 protrudes from the surface of the frame 21, affecting the installation of other components and the overall aesthetics.

[0066] In an optional embodiment, as shown in Figures 1 and 8, when the floating component 1 is in the retracted state, the end of the movable component 12 away from the floating side 113 is flush with the fixed side 112.

[0067] As described above, in the recovery state, the floating component 1 of this disclosure can recover the movable part into the receiving cavity 114. In addition, the movable part 12 is not exposed on the outer surface of the fixed part 11 on the fixed side 112. It can be seen that the floating component 1 of this disclosure has a compact structure, which further limits its overall thickness.

[0068] In an optional embodiment, referring to Figures 2 and 3, the end of the transition portion 124 furthest from the fixed side 112 extends inward to form a first limiting platform 124a for the transition portion 124. The first limiting platform 124a surrounds a mating hole 124b forming the transition portion 124. The outer surface of the locking portion 123 is inclined and gradually narrows in the direction from the fixed side 112 to the floating side 113. When the floating component 1 is in a protruding state, the outer surface of the locking portion 123 is press-fitted with the mating hole 124b at the position of the first limiting platform 124a.

[0069] It should be noted that the inward extension described here refers to the extension of the sidewall of the transition portion 124 toward the axis parallel to the third direction Z of the transition portion 124, thereby forming the first limiting platform 124a and the mating hole 124b. The locking portion 123 is disposed in the mating hole 124b, and the outer surface of the locking portion 123 is inclined, with the outer contour of the locking portion 123 gradually narrowing in the opposite direction of the third direction Z in Figure 3. This structural arrangement allows the locking portion 123 to protrude from the mating hole 124b during sliding. After reaching the maximum stroke, the locking portion 123 is limited by the first limiting platform 124a, thereby achieving an interference fit with the mating hole 124b. The structural arrangement of the locking part 123 and the connecting part 124 in this disclosure results in a smaller thickness occupied by the overlapping structure between the locking part 123 and the connecting part 124 in the protruding state. As a result, when the floating component 1 has the same thickness, the protruding stroke of the movable part 12 in this embodiment is longer than that of the step surface abutment and limiting method. Within the limited setting space, the protruding stroke of the movable part 12 is effectively increased, and the applicability of the floating component 1 is expanded.

[0070] In an optional embodiment, the end of the side wall 111 near the floating side 113 extends inward and forms a second limiting platform 115 for the fixing member 11. The outer surface of the movable member 12 is inclined and gradually narrows in the direction from the fixing side 112 to the floating side 113. When the floating assembly 1 is in the protruding state, the outer surface of the movable member 12 is press-fitted with the receiving cavity 114 at the position of the second limiting platform 115.

[0071] Similarly, the inward extension described here refers to the side wall 111 extending towards the fixing member 11 along an axis parallel to the third direction Z, thereby forming the second limiting platform 115. The outer surface of the transition portion 124 is inclined, and the outer contour of the transition portion 124 gradually narrows in the opposite direction to the third direction Z in FIG3. This structural arrangement allows the transition portion 124 to protrude from the receiving cavity 114 during sliding. After reaching its maximum stroke, the transition portion 124 is limited by the second limiting platform 115, thereby achieving an interference fit with the receiving cavity 114. This structure results in less thickness occupied by the overlapping structure between the fixing member 11 and the transition portion 124 in the protruding state. Therefore, when the floating assembly 1 has the same thickness, compared to the step surface abutment limiting method, the protruding stroke of the movable member 12 in this embodiment is longer. Within the limited setting space, the protruding stroke of the movable member 12 is effectively increased, expanding the applicability of the floating assembly 1.

[0072] Of course, as described above, in other optional embodiments, the structure of the movable member 12 can be configured accordingly based on specific needs and operating conditions. Therefore, the inclined outer surface of the adapter 124 described above essentially corresponds to the inclined outer surface of the movable member 12. That is, in the protruding state, the movable member 12 is interference-fitted with the receiving cavity 114.

[0073] In the embodiments disclosed herein, since the movable member 12 is provided with a connecting part 124 and a locking part 123, when the floating component 1 is in a protruding state, the outer surface of the locking part 123 is in an interference fit with the mating hole 124b at the position of the first limiting platform 124a, and at the same time, the outer surface of the connecting part 124 is in an interference fit with the receiving cavity 114 at the position of the second limiting platform 115.

[0074] As can be seen, the arrangement of the first limiting platform 124a, the second limiting platform 115, the connecting part 124, and the locking part 123 further reduces the thickness occupied by the overlapping structure between the various moving parts of the floating component 1 when it is in the protruding state. As a result, when the floating component 1 has the same thickness, compared with the step surface abutting and limiting method, the protruding stroke of the moving part 12 in this embodiment is longer. Within the limited setting space, the protruding stroke of the floating component 1 is effectively increased, and the applicable range of the floating component 1 is expanded.

[0075] In an optional embodiment, as shown in FIG3, the locking part 123 includes a mounting groove 1231. The mounting groove 1231 communicates with the mounting hole 122. The mounting groove 1231 includes a guide section 1231a and a mounting section 1231b. The guide section 1231a is disposed near the fixing side 112. The inner diameter of the guide section 1231a is smaller than the inner diameter of the mounting section 1231b, and a third limiting stage 1231c of the locking part 123 is formed between the guide section 1231a and the mounting section 1231b. The third limiting stage 1231c is used to engage the fastener.

[0076] In actual use, when the fastener is inserted into the floating component 1, its nut portion will be engaged at the third limiting platform 1231c within the mounting groove 1231. This causes the fastener to drive the movable part 12 to protrude, thereby allowing the abutment surface 121 to abut against the outer surface of the object to be fixed. This ensures the convenience, practicality, and the strength and stability of the connection during use of the floating component 1. Simultaneously, the guide section 1231a provides guidance for the fastener installation, further improving the convenience of installation.

[0077] In an optional embodiment, the inner wall of the guide section 1231a is parallel to the direction from the fixed side 112 to the floating side 113. The inner wall of the mounting section 1231b is inclined, and the inner wall of the mounting groove 1231 gradually narrows in the direction from the fixed side 112 to the floating side 113.

[0078] When the fastener nut is small or the surface of the nut facing the screw is beveled, it may not be able to be locked onto the third limiting stage 1231c. In this case, the inclined mounting section 1231b can act as a limiting element. Similar to what is described above, the fastener nut can form an interference fit with the mounting section 1231b, thereby ensuring the stability of the fastener when it is installed on the moving part 12.

[0079] In an optional embodiment, one end of the fastener is engaged with the mounting section 1231b, and the other end passes through the mounting hole 122 and extends in a direction from the fixed side 112 to the floating side 113. In another optional embodiment, one end of the fastener is engaged with the third limiting platform 1231c, and the other end passes through the mounting hole 122 and extends in a direction from the fixed side 112 to the floating side 113.

[0080] In practical applications, common screws fall into two categories: one where the connection between the nut and stud is a stepped surface (e.g., flathead screws, roundhead screws); and another where the connection is conical (e.g., countersunk screws, crown head screws). In other words, the connection between the screw's nut and stud is a flat surface and a beveled surface, respectively. As mentioned above, if a screw with a stepped nut-stud connection is used, it can be secured on the third limiting platform 1231c. However, if a screw with a conical nut-stud connection is used, slippage or wear may occur when secured on the third limiting platform 1231c. Therefore, in this disclosure, the inner wall of the guide section 1231a is set to be parallel to the third direction Z, while the inner wall of the mounting section 1231b is set at an inclination. In this way, when a screw with a cone-shaped structure for connecting the nut and the stud is used, the nut can be placed on the mounting section 1231b, avoiding slippage or wear caused by the inner wall of the mounting groove 1231 and the outer surface of the screw not fitting together.

[0081] In an optional embodiment, the fixing member 11 includes a blocking portion 116, which is disposed at one end of the side wall 111 near the fixed side 112. When the floating assembly 1 is in the retracted state, the blocking portion 116 is attached to the movable member 12.

[0082] As shown in Figures 1 and 4, the blocking part 116 ensures that when the floating component 1 is in the retracted state, the movable part 12 will not be exposed or detached from the fixed side 112 of the fixed part 11. This further effectively limits the overall thickness of the floating component 1 and prevents the movable part 12 from falling off the fixed side 112 or protruding from the surface of the fixed part 11, which would affect the installation of other components and the overall aesthetics.

[0083] In an optional embodiment, as shown in Figures 1 and 4, the movable member 12 further includes a docking groove 125, which is disposed at the end of the movable member 12 away from the floating side 113. When the floating assembly 1 is in the retracted state, the blocking part 116 is engaged in the docking groove 125.

[0084] As described above, this disclosure provides a blocking portion 116 on the fixing member 11 to prevent the movable member 12 from being exposed or detached from the fixing side 112. In the embodiment shown in FIG4, a docking groove 125 is provided at the corresponding position of the movable member 12, so that in the retracted state, the blocking portion 116 will be engaged in the docking groove 125, so that the blocking portion 116 and the docking groove 125 overlap, thereby further improving the structural compactness and space utilization of the floating assembly 1.

[0085] In an optional embodiment, the docking groove 125 includes a first groove (not shown) and a second groove. The first groove is disposed on the locking part 123, and the second groove is disposed on the adapter part 124, and the first groove and the second groove are in communication. When the floating component 1 is in the retracted state, the blocking part 116 is simultaneously engaged in the first groove and the second groove.

[0086] As described above, in the embodiments disclosed in this disclosure, the movable component 12 includes two layers: a locking portion 123 and a connecting portion 124. Therefore, the docking groove 125 of this disclosure is configured as a first groove and a second groove respectively provided on the locking portion 123 and the connecting portion 124, and the first groove and the second groove are connected. In the retracted state, the main body of the blocking portion 116 is locked in the second groove, and the end is locked in the first groove, thereby blocking both the locking portion 123 and the connecting portion 124 simultaneously, ensuring that neither the locking portion 123 nor the connecting portion 124 will be exposed or detached from the fixed side 112, further improving the safety, structural compactness, and space utilization of the floating component 1.

[0087] In the actual assembly process, the movable part 12 is inserted into the fixed part 11 from the fixed side 112. Before the movable part 12 is installed, a protrusion is provided at one end of the side wall 111 near the fixed side 112. One end of the protrusion is connected to the side wall 111, and the other end extends in the Z direction away from the floating side 113. After the movable part 12 is inserted into the receiving cavity 114, the protrusion is bent to form a blocking part 116. Of course, in other optional embodiments, the blocking part 116 can also be fixed at the end of the side wall 111 near the fixed side 112 by welding, bonding or other fixing methods after the movable part 12 is installed. Therefore, this disclosure does not limit this.

[0088] In an optional embodiment, the side wall 111 includes a first side wall 111a and a second side wall 111b. The curvature of the first side wall 111a is different from the curvature of the second side wall 111b.

[0089] In other words, the overall shape of the side wall 111 is not a complete circle, thus preventing the movable part 12 from rotating within the receiving cavity 114. Therefore, when the floating assembly 1 is in the protruding state, the movable part 12 can only slide along the third direction Z and will not rotate around an axis parallel to the third direction Z. This avoids the situation where the blocking part 116 and the docking groove 125 are misaligned due to the rotation of the movable part 12, ensuring that the blocking part 116 can be engaged in the docking groove 125 and guaranteeing the structural compactness of the floating assembly 1.

[0090] In the embodiment shown in Figure 4, the first sidewall 111a is arc-shaped, while the second sidewall 111b is flat. Correspondingly, the movable member 12 is also configured as a combination of arc and flat shapes to cooperate with the structure of the fixed member 11. This structural design not only ensures the smoothness of the sliding of the movable member 12 in the receiving cavity 114, but also ensures that the movable member 12 will not rotate around its axis, thus preventing misalignment between the blocking part 116 and the mating groove 125.

[0091] In an optional embodiment, as shown in Figures 5, 6, and 7, the frame 21 includes an adapter bracket 211 and a mounting bracket 212. One end of the mounting bracket 212 is connected to the adapter bracket 211, and the other end extends in a direction perpendicular to and away from the adapter bracket 211. The floating component 1 is disposed on the mounting bracket 212.

[0092] In practical applications, the adapter bracket 211 is used to connect to the interface of the hard drive 3, while the mounting bracket 212 is used to physically fix it to the hard drive 3. The floating component 1 is set on the mounting bracket 212, which facilitates the fixed connection between the mounting bracket 212 and the hard drive 3.

[0093] In an optional embodiment, there are two mounting brackets 212, which are symmetrically arranged. There are multiple floating components 1, each disposed on one of the two mounting brackets 212.

[0094] The symmetrical arrangement of the two mounting brackets 212 and multiple floating components 1 ensures that the hard drive 3 is more evenly stressed and more stably installed on the bracket 2. In actual production and use, the structure of the frame 21, the number of floating components 1, and their installation positions can be adjusted according to actual specifications, dimensions, and user requirements. For example, two floating components 1 can be symmetrically positioned on the mounting brackets 212 away from the adapter bracket 211. During installation, the hard drive 3 is first connected to the adapter bracket 211, and then the two floating components 1 fix the end of the hard drive 3 away from the adapter bracket 211. Alternatively, three, four, or more floating components 1 can be used to improve the stability of the hard drive 3 after installation. Therefore, this disclosure does not impose any limitations on this arrangement.

[0095] In the embodiment shown in Figure 5, four floating components 1 are symmetrically arranged on the two mounting brackets 212. When the hard drive 3 fixed by the bracket 2 can be fixed to the adapter bracket 211, only the two floating components 1 away from the adapter bracket 211 are needed to further fix the hard drive 3. When the hard drive 3 fixed by the bracket 2 is too small to be fixed to the adapter bracket 211, all four floating components 1 are used to fix the hard drive 3. Therefore, the structure of the bracket 2 disclosed herein can accommodate hard drives 3 of different sizes, ensuring connection stability while avoiding the limitation of the mounting bracket 212's strength due to an excessive number of floating components 1.

[0096] In an optional embodiment, the side wall 111 extends through the mounting bracket 212. Furthermore, the surface of the side wall 111 near the fixed side 112 is flush with the surface of the mounting bracket 212. In another optional embodiment, the surface of the side wall 111 near the floating side 113 is flush with the surface of the mounting bracket 212. However, in the embodiments disclosed herein, both the surfaces of the side wall 111 near the fixed side 112 and near the floating side 113 are flush with the surface of the mounting bracket 212. Therefore, this disclosure does not impose any limitations.

[0097] As described above, the side wall 111 of the fastener 11 is designed so that the end of the side wall 111 does not protrude from the outer surface of the mounting bracket 212, thereby ensuring that the floating component 1 has a more compact structure and higher integrity, and further limiting its overall thickness.

[0098] In an optional embodiment, as shown in FIG7, the mounting bracket 212 includes a recessed groove 212a and a through hole 212b. The recessed groove 212a is formed on the side of the mounting bracket 212 facing the mounting space 22. The through hole 212b is disposed in the recessed groove 212a and connects the two sides of the mounting bracket 212 along the thickness direction.

[0099] As can be seen, the mounting bracket 212 of this disclosure connects both sides of the mounting bracket 212 along the thickness direction (i.e., the third direction Z) through the through hole 212b, facilitating the installation of the side wall 111 through the mounting bracket 212. Simultaneously, a recessed groove 212a is formed on the side of the mounting bracket 212 facing the installation space 22 to fix the side wall 111, allowing the fastener 11 to be more securely installed on the mounting bracket 212. Furthermore, the recessed groove 212a retains most of the structure of the mounting bracket 212 in the thickness direction, ensuring the strength of the mounting bracket 212, thereby providing higher stability and safety for the subsequent use of the bracket 2.

[0100] In an optional embodiment, referring to Figures 5 and 6, the fastener 11 further includes a mounting portion 117. The mounting portion 117 is connected to one end of the side wall 111 near the floating side 113. The mounting portion 117 is disposed in the recess 212a, and the side wall 111 is disposed in the through hole 212b. The surface of the mounting portion 117 near the floating side 113 is flush with the surface of the mounting bracket 212 facing the mounting space 22.

[0101] As can be seen, the floating component 1 of this disclosure has a mounting part 117 on the side wall 111, which can be engaged in the sinkhole 212a, thereby fixing the side wall 111 in the through hole 212b. The structural design of the floating component 1, while ensuring its firm installation, also ensures that the end of the fixing member 11 near the floating side 113 does not protrude from the surface of the mounting bracket 212. As described above, this structural design further ensures that the floating component 1 has a more compact structure and higher overall integrity, avoiding situations where the protrusion of part of the floating component 1 affects the installation of other components.

[0102] In an optional embodiment, as shown in FIG7, the bracket 2 further includes a light guide groove 23. The light guide groove 23 is formed on the side of the mounting bracket 212 facing the mounting space 22 and is spaced apart from the recessed groove 212a. The light guide groove 23 is used to mount the light guide column of the bracket 2.

[0103] The light guide groove 23 provides greater convenience and overall integrity for the installation of the light guide post of the bracket 2, so that the light guide posts matched with different specifications of hard drives 3 can be installed on the bracket 2.

[0104] In an optional embodiment, the bracket 2 further includes a first light guide post and a second light guide post. The first light guide post is disposed on the side of the adapter bracket 211 facing the mounting space 22. The second light guide post is disposed within the light guide groove 23. In actual installation, for example, if the first type of hard drive 3 being installed can be connected to the light guide post on the adapter bracket 211, it can be directly connected to the first light guide post; however, if other types of hard drives 3 cannot be connected to the first light guide post on the adapter bracket 211, a corresponding light guide post can be disposed in the light guide groove 23, allowing the hard drive 3 to be connected to the second light guide post. This arrangement ensures that the bracket 2 is compatible with the installation of hard drives 3 of different specifications and interfaces. Meanwhile, since the light guide groove 23 is located on the side of the mounting bracket 212 facing the mounting space 22, as can be seen from the figure, that is, on the same surface as the recessed groove 212a, after the hard drive 3 with matching specifications is installed in the bracket 2, the floating component 1, the fasteners and the fixed connection of the hard drive 3 can enclose the light guide groove 23 between the mounting bracket 212 and the hard drive 3. In other words, the second light guide column set in the light guide groove 23 can be pressed into the enclosed space, thereby effectively improving the stability and safety of the light guide column after installation.

[0105] In an optional embodiment, as shown in Figures 6 and 7, there are multiple light guide grooves 23, which are arranged sequentially at intervals along the length of the mounting bracket 212. In the width direction of the mounting bracket 212, the light guide grooves 23 are spaced apart from the recessed grooves 212a.

[0106] It should be noted that the light guide grooves 23 mentioned above, which are arranged sequentially and at intervals along the length of the mounting bracket 212, refer to the light guide grooves 23 extending along the second direction Y as shown in the figure, and being arranged at intervals along the second direction Y with their ends facing each other, rather than being arranged side by side. The statement that the light guide grooves 23 and the recessed grooves 212a are spaced apart along the width direction of the mounting bracket 212 refers to the light guide grooves 23 and the recessed grooves 212a being spaced apart along the first direction X as shown in the figure. The shortest distance between the light guide grooves 23 and the recessed grooves 212a is greater than or equal to 1 mm and less than or equal to 3 mm. Specifically, depending on the actual installation conditions (e.g., the width of the mounting bracket 212, the width of the recessed grooves 212a, and the width of the light guide grooves 23) or the specific needs of the user, the shortest distance between the light guide grooves 23 and the recessed grooves 212a can be set to 1 mm, 1.5 mm, 2 mm, 2.2 mm, 2.5 mm, or 3 mm, and this disclosure does not impose any restrictions on this. In the embodiments disclosed herein, the shortest distance between the light guide groove 23 and the recessed groove 212a is set to 2.2mm. This setting not only ensures that the light guide groove 23 and the recessed groove 212a will not interfere with each other, but also allows for the installation of the floating component 1 and the light guide column on the limited structure of the mounting bracket 212, effectively improving the space utilization of the bracket 2 and the integrity and compactness of the structure.

[0107] The above structural design ensures that the structure of the light guide groove 23 does not interfere with the structure of the recessed groove 212a, and allows for the simultaneous arrangement of the light guide groove 23 and the recessed groove 212a within the limited structure of the mounting bracket 212. This design not only satisfies the docking and installation requirements of the bracket 2 for hard drives 3 of different sizes, but also ensures the integrity and structural strength of the frame 21, thereby guaranteeing the stability of the frame 21 after the hard drive 3 is installed.

[0108] In an optional embodiment, as shown in FIG8, when the width of the hard disk 3 is equal to the width of the mounting space 22, the end of the movable member 12 away from the fixed side 112 is flush with the floating side 113 of the fixed member 11. As shown in FIG9, when the width of the hard disk 3 is less than the width of the mounting space 22, the movable member 12 protrudes from the fixed side 112 toward the floating side 113, and the abutment surface 121 abuts against the side surface of the hard disk 3.

[0109] In the embodiments disclosed in this disclosure, EDSFF interface hard drives and U.2 interface hard drives are used as examples. Referring to Figure 8, the size of the EDSFF interface hard drive is larger than that of the U.2 interface hard drive, and its status indicator light is built into the hard drive, requiring no additional installation. Therefore, during installation, simply placing the hard drive into the installation space 22 will push the movable parts 12 of the floating components 1 on both sides back into the receiving cavity 114, so that the floating components 1 are in a retracted state. On the adapter bracket 211 of the bracket 2, there are pins and light guides (i.e., the first light guides described above) that match the EDSFF interface hard drive. The pins are set along the second direction Y, and the surface of the hard drive facing the adapter bracket 211 is provided with matching pin holes, so that after the hard drive is placed into the installation space 22, the pins and pin holes match, and the interface of the hard drive matches and connects with the light guide, thereby fixing the end of the hard drive facing the adapter bracket 211. At this point, simply insert the fasteners into the two floating components 1 that are away from the adapter bracket 211, and connect them to the hard drive through the mounting holes 122 to complete the installation of the hard drive.

[0110] Referring to Figure 9, when installing a U.2 interface hard drive, because the U.2 interface hard drive is smaller than the EDSFF interface hard drive, and its light guide column interface is different from EDSFF, the status indicator light requires an additional hard drive backplate. Therefore, during installation, the hard drive must first be placed in the installation space 22, and the hard drive interface must be connected to the light guide column (i.e., the second light guide column mentioned above) located in the light guide groove 23 to guide the hard drive's status information to the display panel on the hard drive backplate via light. Since the adapter bracket 211 does not have a fixing component that matches the U.2 interface hard drive, four floating components 1 need to be fixed simultaneously. Because the U.2 interface hard drive is smaller, all four floating components 1 are in a protruding state after the fasteners are inserted into the floating components 1. Thus, although there is a gap between the hard drive and the mounting bracket 212, the contact surface 121 of the floating component 1 is attached to the surface of the hard drive, thereby preventing the mounting bracket 212 from bending under stress. After all four floating components 1 are securely connected, the installation of the U.2 interface hard drive is complete.

[0111] Of course, in practical applications, the size of the bracket 2, the number of floating components 1, and the installation position can be adjusted according to the specifications of different interface hard drives 3 and the specific needs of the users, so as to accommodate the installation of hard drives 3 of different sizes. Therefore, this disclosure does not impose any limitations in this regard.

[0112] It should be noted that the technical solutions or features described in the above embodiments can be combined or complemented by each other without conflict. The scope of protection of this disclosure is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
