[0037] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0038] like Figure 1 As shown, the first aspect of this disclosure provides a fixing device, including: a support member 100 and a fixing member 200;

[0039] The support member 100 has a first region 110 and a second region 120 arranged adjacent to each other. The first region 110 has a through hole 130 and the second region 120 has a limiting side 121.

[0040] The fastener 200 is located in the first region 110 and can pass through the through hole 130. The fastener 200 is adapted to the support 100 for limiting the target 500.

[0041] Understandably, the support member 100 is the basic frame of the fixing device, mainly used to support the fixing member 200 and, together with the fixing member 200, to provide a limiting function for the target member 500. The support member 100 adopts a partitioned arrangement, having an adjacent first region 110 and a second region 120. A through hole 130 is provided in the first region 110 for the fixing member 200 to pass through. The design of the through hole 130 needs to be adjusted according to the size of the target member 500 and the installation requirements, for example, a circular, elliptical, or polygonal hole. A limiting side 121 is provided in the second region 120 for limiting the target member 500 laterally and / or longitudinally.

[0042] The fastener 200 passes through the through hole 130 and is limited to the support 100. The fastener 200 matches the through hole 130 of the support 100 and can be connected to the support 100 by means of threads, snap-fit, etc.

[0043] In the process of fixing the target part 500, the fixing part 200 is passed through the through hole 130 of the support part 100 and its relative position with the target part 500 is adjusted. By rotating the fixing part 200 (if the fixing part 200 needs to be fixed to the target part 500 by means of threaded connection) or pressing the fixing part 200 (if the fixing part 200 needs to be fixed to the target part 500 by means of disassembly), the fixing part 200 is brought closer to the target part 500. At this time, the fixing part 200 and the support part 100 act on the target part 500 at the same time, so as to achieve the effect of fixing and limiting the target part 500.

[0044] The fastener 200, in cooperation with the support 100, can restrict the left-right or front-back movement of the target 500 through the second area 120 of the support 100 via the limiting side 121, and can also press the first area 110 of the support 100 against the surface of the target 500 after the fastener 200 passes through the through hole 130, thereby restricting the up-down movement of the target 500.

[0045] The support component 100 can be made of plastic, including thermosetting plastics and thermoplastic plastics. Thermosetting plastics, such as epoxy resin, cannot be melted or dissolved again after curing to give it high heat resistance and mechanical strength. Thermoplastic plastics are plastic materials that can soften and flow when heated and can be hardened and molded after cooling, such as polyethylene and polypropylene. It can also be non-conductive materials such as ceramics.

[0046] By enclosing the fastener 200, such as screws, with the support 100, the screws of the traditional design can be prevented from rolling off and being lost during disassembly, and can be effectively prevented from being accidentally stuck inside the machine.

[0047] For example, when fixing server hard drives, motherboard 400 expansion cards, etc., the fixing device proposed in this application can replace traditional screw fixing and avoid the risk of electric shock from screws falling off.

[0048] In some embodiments, such as Figure 1-2 As shown, the first region 110 has a boss portion 111, which is connected to a limiting side 121. The limiting side 121 is used to adapt to the side wall of the connecting target member 500, and the boss portion 111 is used to adapt to the surface of the connecting target member 500.

[0049] Understandably, a boss 111 is added to optimize the fixing effect of the target part 500. The boss 111 is located in the first region 110 of the support 100 and is directly connected to the limiting side 121, so that the boss 111 can both contact the surface of the target part 500 and form a cooperative limiting with the side wall of the target part 500 through the limiting side 121.

[0050] The boss 111 can be a planar boss, which can increase the contact area when it is attached to the surface of the target part 500. On the one hand, it increases the stability of fixing the target part 500, and on the other hand, the large contact area of ​​the boss 111 disperses the pressure applied by the fixing part 200, preventing the target part 500 from being deformed or damaged due to excessive local stress.

[0051] The boss portion 111 can also be a stepped boss, which can adapt to the target part 500 of different thicknesses through multiple steps. The boss portion 111 can also be an arc-shaped boss, which can fit the curved surface of the target part 500.

[0052] The combined effect of the boss 111 and the limiting side 121 forms a three-dimensional constraint, ensuring stability even when the target component 500 is subjected to external impacts (such as vibration or collision). For example, when fixing a hard drive in a server chassis, the boss 111 can prevent the hard drive from becoming loose due to chassis vibration.

[0053] Furthermore, by adjusting the curvature or stepped structure of the boss portion 111, it can be adapted to target parts 500 of different shapes (such as cylindrical hard drives and rectangular circuit boards). For example, for hard drives with heat dissipation fins on the edges, the boss portion 111 can be designed to be arc-shaped, avoiding the heat dissipation structure and fitting the hard drive body.

[0054] In some embodiments, the boss portion 111 extends along a direction perpendicular to the thickness of the first region 110;

[0055] The through hole 130 provided on the boss portion 111 is a strip-shaped hole, and the fastener 200 can move along the length direction of the through hole 130 to adjust its position.

[0056] Understandably, to flexibly adapt to the installation of various types of target components 500, the boss portion 111 is extended in a direction perpendicular to the thickness direction of the first region 110. For example, the boss portion 111 extends horizontally to form a beam or guide rail structure. During assembly, it can cover the target component 500, increasing the stability of the target component 500, and is suitable for elongated target components 500, such as elongated circuit boards or wide-body hard drives.

[0057] The strip-shaped hole is provided on the boss portion 111 and is parallel to the extension direction of the boss portion 111, so that the fastener 200 can interact along the length direction of the strip-shaped hole to adjust the installation position.

[0058] In some embodiments, such as Figure 3 As shown, the boss portion 111 is connected to the limiting piece 300, the limiting piece 300 is provided corresponding to the through hole 130, and the limiting piece 300 is limitedly connected to the fixing member 200.

[0059] Understandably, the limiting piece 300 is directly connected to the surface of the boss portion 111, and a limiting through hole is provided in the limiting piece 300. The limiting through hole corresponds to the position of the through hole 130, and the diameter of the limiting through hole is smaller than the diameter of the through hole 130. At the same time, a mounting portion is provided near the end of the fixing member 200. The outer contour of the mounting portion is adapted to the diameter of the limiting through hole. After the fixing member 200 passes through the through hole 130, the limiting piece 300 is sleeved on the mounting portion to limit the fixing member 200 in the through hole 130 of the boss portion 111.

[0060] When the through hole 130 is a strip hole, the fastener 200 can move along the length of the through hole 130 according to the fastening requirements. At this time, the limiting member sleeved on the mounting part of the fastener 200 can move with the fastener 200.

[0061] With the above structure, the fastener 200 and the support 100 are integrated into one piece, and the target part 500 can be fixed by the boss portion 111 of the support 100. Furthermore, the fastener 200 can use common screw types, avoiding the need to produce screws with new structures for fixing the target part 500.

[0062] In some embodiments, such as Figure 2 As shown, an annular groove 210 is provided on the outer periphery of the fastener 200, and the limiting piece 300 is assembled in the annular groove 210 so that the fastener 200 and the support 100 are connected in a limiting manner.

[0063] Understandably, a mounting portion is provided at the first end near the fixing member 200. The mounting portion has an annular groove 210 structure, which is formed on the outer periphery of the fixing member 200. The annular groove 210 can be a circular groove that matches the opening of the limiting piece 300.

[0064] The limiting piece 300 is a flat, sheet-like structure with an opening in the middle. Its outer contour can be circular, rectangular, or the like. The diameter of the opening in the limiting piece 300 is smaller than the diameter of the through hole 130 and is adapted to the outer contour of the annular groove 210 so that the limiting piece 300 is assembled on the annular groove 210. The outer contour dimension of the fixing member 200 varies along the axial direction. The outer contour dimension of the first end of the fixing member 200 is the largest and is larger than the inner diameter of the through hole 130. The outer contour dimension of the annular groove 210 located near the first end is the smallest. The outer contour dimension of the second end is between the first end and the annular groove 210.

[0065] During the assembly of the fastener 200 and the support 100, the second end of the fastener 200 passes through the through hole 130 from one side of the boss portion 111, and then the limiting piece 300 moves from the other side of the boss portion 111 through the second end of the fastener 200 to the first end until it is fitted into the annular groove 210 of the fastener 200. Thus, the fastener 200 is restricted from coming out of the through hole 130 by the engagement of the limiting piece 300 with the annular groove 210.

[0066] Among them, the limiting piece 300 can be a rubber gasket with elastic deformation characteristics to meet assembly requirements.

[0067] In some embodiments, the outer contour of the support member 100 may include at least one of a strip shape, a semi-circle shape, an arc shape, and a trapezoid shape, and the limiting side 121 is formed on the long side of the support member 100.

[0068] Understandably, the outer contour of the support 100 is designed in the aforementioned elongated, semi-circular, arc-shaped, or trapezoidal form, making it easy for the user to grip during installation and easy to spot and retrieve even if it falls. The limiting side 121 is located on the long side (longest side) of the support 100, utilizing the maximum contact area of ​​the long side to achieve a stronger limiting effect. The limiting side 121, with its long-side layout, significantly enhances the constraint force on the target component 500 through its large contact area. Furthermore, the fixing device formed by the support 100 wrapping around the fixing component 200 increases the physical visual difference compared to traditional screws, while also reminding the user that there is a clearly visible support component on this side of the target component 500 for locking and positioning. Simultaneously, it reduces the risk of the fixing component splashing or slipping into the machine during the installation or removal of the target component 500.

[0069] In some embodiments, such as Figure 2-3 As shown, the support member 100 has a first support portion 140 and a second support portion 150. The first support portion 140 has a limiting side 121. The first support portion 140 and the boss portion 111 have a height difference to form a limiting space 160.

[0070] The first surface of the first support portion 140 and the second surface of the second support portion 150 have a height difference to form a clearance space 170. It can be understood that there is a vertical height difference between the first support portion 140 and the boss portion 111 to form a limiting portion for accommodating the edge of the target part 500 or other structures located at the edge of the target part 500, such as internally threaded pillars or heat dissipation fins.

[0071] The second support part 150 and the bottom or surface of the first support part 140 form a horizontal height difference, constituting a clearance space 170, which is used to avoid other components of the adjacent target part 500. The clearance space 170 avoids interference between the target part 500 and other components, and improves the compactness of the device.

[0072] The second support unit 150 may not directly participate in the limiting, but rather optimize the internal layout of the device by avoiding space.

[0073] The boss portion 111 is fixedly connected to the first support portion 140, and is disposed on the limiting side 121, and extends in a direction away from the limiting side 121;

[0074] In this configuration, a limiting space 160 is formed by a vertical height difference between one side of the boss portion 111 and the first support portion 140; conversely, a receiving space is formed by a vertical height difference between the other side of the boss portion 111 and the first support portion 140. The receiving space can accommodate the first end of the fastener 200, such as the screw head, so that the assembled fastener 200 and support portion 100 are structurally compact and space-saving.

[0075] In some embodiments, the first surface of the first support portion 140 and the second surface of the second support portion 150 have a height difference greater than 1 mm.

[0076] Understandably, the first surface of the first support part 140 can contact the bearing surface, which can be the surface of the bearing target part 500, or the bearing surface can be the surface of the target part 500.

[0077] For example, if the target component 500 is a portable hard drive, the bearing surface can be the surface of the motherboard 400. The second surface of the second support portion 150 forms a height difference with the first surface to create a clearance space 170. This height difference is greater than 1mm, and can be 2.25mm. The clearance space 170 formed by the height difference can avoid other components adjacent to the target component 500. For example, if a capacitor is installed on the motherboard 400 near the portable hard drive, and the maximum thickness of the capacitor is 2.0mm, a gap of 0.25mm is left to ensure that the clearance space 170 avoids this capacitor and meets installation tolerances. This makes the difference between the second surface of the second support portion 150 and the first surface of the first support portion 140 equal to 2.0mm + 0.25mm = 2.25mm. This can be understood as the first surface of the first support portion 140 contacting the bearing surface of the target component 500, with a 2.25mm gap between the second surface of the second support portion 150 and the bearing surface, forming the clearance space 170.

[0078] In some embodiments, such as Figure 2-3 As shown, the thickness of the second region 120 is greater than the thickness of the first region 110.

[0079] Understandably, based on the existing fixing device, further optimization of the device's mechanical properties, space utilization, and functional adaptability can be achieved through structural thickness differences.

[0080] The first region 110 has a smaller thickness and is usually located in the core area of ​​the device (such as the mounting surface near the target component 500). During installation, it can hold the target component 500 and provide basic fixed support.

[0081] The second region 120 has a larger thickness and is usually located on the periphery or in the reinforcement area of ​​the device. It is used to enhance the structural strength and adapt to large or heavy-duty target parts 500. At the same time, due to the larger thickness of the second region 120, it can be used to form a clearance space 170.

[0082] like Figure 4-5 As shown, in a second aspect, an electronic device is proposed, including a motherboard 400, a target component 500, and a fixing device. The motherboard 400 is provided with a fixing part 410, the target component 500 is connected to the motherboard 400, and the fixing device is installed on the motherboard 400. The fixing device also includes a support component 100 and a fixing component 200, which are connected to the fixing part 410 through the fixing component 200.

[0083] The support member 100 has a first region 110 and a second region 120 arranged adjacent to each other. The first region 110 has a through hole 130 and the second region 120 has a limiting side 121.

[0084] The fastener 200 is located in the first region 110 and passes through the through hole 130. The fastener 200 is adapted to the support 100 to connect and limit the target 500.

[0085] Understandably, in electronic devices, the reliability of the fixing device can directly affect the stability and service life of the target component 500. The electronic device can be a server, industrial control cabinet, laptop, host, etc., and the target component 500 can be a hard drive, circuit board, module, etc. The target component 500 is connected to the motherboard 400 through the fixing device.

[0086] As a core component of the electronic device, the motherboard 400 has a mounting position, namely a fixing part 410, for fixing. There can be one or more fixing parts 410, which can be threaded holes, internal threaded posts, plug holes, etc., for fitting with the fixing part 200. The fixing device is installed on the motherboard 400 to securely connect and limit the target part 500, preventing displacement or loosening.

[0087] The fixing device includes two core components: a support 100, which provides support and limiting functions, and a fixing 200, which fixes the support 100 to the main board 400, serving as a connection and locking mechanism.

[0088] At least one through hole 130 is provided in the first region 110 of the support member 100. The position of the through hole 130 corresponds to the fixing part 410 on the motherboard 400. The fixing member 200 (such as a screw) passes through the through hole 130, so that the support member 100 can be connected to the motherboard 400 and achieve axial positioning, ensuring that the support member 100 is firmly installed on the motherboard 400.

[0089] The number of through holes 130 can be multiple, which can improve the stability of the connection. Furthermore, the through holes 130 can be set to be elongated strip-shaped through holes 130, which can be adjusted along the length direction to adapt to different layouts.

[0090] The second region 120 of the support component 100 is located adjacent to the first region 110 and has a limiting side 121. The limiting side 121 can be a limiting surface, a limiting protrusion, a limiting groove, etc., used to contact the side wall of the target component 500 for lateral limiting, preventing the target component 500 from shifting or falling off due to vibration, gravity, thermal expansion, etc. after installation. It can match the shape of the target component 500 to achieve precise fit.

[0091] The fastener 200 fixes the support 100 onto the motherboard 400 and also engages with the through hole 130 in the first region 110 of the support 100 to form a stable mechanical connection.

[0092] During installation, the support component 100 can be placed in the preset position of the motherboard 400, and the fixing component 200 (screw) placed in the through hole 130 of the first area 110 of the support component 100 can be aligned with the fixing part 410 on the motherboard 400 and tightened. The target component 500 can be pressed by the limiting side 121, and the limiting side 121 restricts the movement of the target component 500 in the lateral or depth direction to complete the installation and limiting of the target component 500.

[0093] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described.
