[0040] Figure 1 This is one of the structural schematic diagrams of the hard disk fixing member provided by the embodiment of the utility model (the side panel assembly is in the unfolded state); Figure 2 This is the second structural schematic diagram of the hard disk fixing member provided by the embodiment of the utility model (the side panel assembly is in a limited position state).

[0041] See also Figure 1 and Figure 2 An embodiment of the utility model provides a hard disk fixing component, which includes a fixing body 100 and a side plate assembly 200.

[0042] The fixed body 100 has a rectangular structure, and may include the bracket 110 and the end plate 120 described below, and the end plate 120 is located at the end of the bracket 110. The fixed body 100 may also be provided in one piece, consisting of a bottom and an end, and the end is provided at one end of the bottom, and the end and the bottom limit a rectangular accommodation space, and the accommodation space is used to install the hard disk body 500.

[0043] The side plate assembly 200 is arranged on at least one side of the fixed body 100 except the side opposite to the end plate 120, that is, the side plate assembly 200 can be arranged on any side of the fixed body 100, or on both sides of the fixed body 100 at the same time. The side plate assembly 200 is movably connected to the fixed body 100 through the connecting rod mechanism 300; under the action of external force, the side plate assembly 200 is suitable for switching between the unfolded state and the limited state. In the unfolded state, the hard disk body 500 is disassembled or installed on the fixed body 100, and in the limited state, the hard disk body 500 is kept on the fixed body 100. That is, when the side plate assembly 200 is in the unfolded state under the action of external force, it is equivalent to expanding the accommodation space, which facilitates the installation or removal of the hard disk body 500; when the side plate assembly 200 is in the limited state under the action of external force, it is equivalent to that the hard disk body 500 is already located in the accommodation space, and the side plate assembly 200 limits the degree of freedom of the hard disk body 500, so as to achieve the purpose of tool-free installation of the hard disk body 500.

[0044] It is understandable that the hard disk fixing member provided by the embodiment of the utility model is provided with a connecting rod mechanism 300 between the side panel assembly 200 and the fixed body 100, so that the side panel assembly 200 is movably connected with the fixed body 100 through the connecting rod mechanism 300. By applying force to the side panel assembly 200, the side panel assembly 200 can be switched between the unfolded state and the limited state. In the unfolded state, the hard disk body 500 is disassembled or installed on the fixed body 100. In the limited state, the hard disk body 500 is kept on the fixed body 100, so as to achieve the purpose of tool-free installation of the hard disk body 500, facilitate the quick disassembly and installation of the hard disk body 500, facilitate the after-sales maintenance of the hard disk body 500, and ensure the service life of the hard disk fixing member while improving the user experience. It has high economy and practicality.

[0045] Furthermore, when the side panel assembly 200 is self-locked under the action of external force, the connecting rod mechanism 300 is located in the gap between the side panel assembly 200 and the fixed body 100. The connecting rod mechanism 300 will not occupy too much space of the hard disk fixing part, and can meet the size requirements of the general server for the hard disk assembly.

[0046] Continue reading Figure 1 In some embodiments of the present invention, the connecting rod mechanism 300 includes at least one connecting rod 310, one end of the connecting rod 310 is connected to the fixed body 100, and the other end of the connecting rod 310 is connected to the side plate assembly 200. When the side plate assembly 200 is in the limited state, the connecting rod 310 is received in the gap between the fixed body 100 and the side plate assembly 200, and the connecting rod 310 is respectively in contact with the fixed body 100 and the side plate assembly 200 to achieve self-locking.

[0047] Equivalently, at least one connecting rod mechanism 300 may be provided, or two or three connecting rod mechanisms 300 may be provided in parallel with each other in order to improve the stability and reliability of the connecting rod mechanism 300. The specific setting may be determined according to actual usage and will not be elaborated here.

[0048] Since there are two forces in the kinematic pair of the connecting rod mechanism 300, the driving force that makes the connecting rod mechanism 300 move and the friction force that hinders the movement of the connecting rod mechanism 300. For the connecting rod mechanism 300, when the combined force of the external forces acts within the friction circle, the rotating pair of the connecting rod mechanism 300 is self-locking. Therefore, when the connecting rod mechanism 300 is provided with a connecting rod 310, when the side plate assembly 200 is in the limited state, the connecting rod 310 is received in the gap between the fixed body 100 and the side plate assembly 200, and the connecting rod 310 is respectively in contact with the fixed body 100 and the side plate assembly 200 to meet the self-locking condition, that is, the friction between the connecting rod 310 and the fixed body 100 and the side plate assembly 200 can keep the side plate assembly 200 in the limited state.

[0049] Continue reading Figure 1 and Figure 2 In some embodiments of the present invention, the side panel assembly 200 includes a first side panel 210 and a second side panel 220. The first side panel 210 is disposed on one side of the fixed body 100, and the second side panel 220 is disposed on the other side opposite to the fixed body 100. Either the first side panel 210 or the second side panel 220 is movably connected to the fixed body 100 through a connecting rod mechanism 300.

[0050] That is, the first side plate 210 can be fixedly connected to one side of the fixed body 100, and the second side plate 220 can be connected to the other side of the fixed body 100 through the connecting rod mechanism 300, which is equivalent to the first side plate 210 mainly playing a positioning role, and the second side plate 220 mainly playing a limiting role. When the hard disk body 500 is installed on the fixed body 100, the first side plate 210 and the second side plate 220 cooperate to keep the hard disk body 500 in the fixed body 100.

[0051] The second side plate 220 can also be fixedly connected to one side of the fixed body 100, and the first side plate 210 can be connected to the other side of the fixed body 100 through the connecting rod mechanism 300, which is equivalent to the second side plate 220 mainly playing a positioning role, and the first side plate 210 mainly playing a limiting role. When the hard disk body 500 is installed on the fixed body 100, the second side plate 220 and the first side plate 210 cooperate to keep the hard disk body 500 in the fixed body 100.

[0052] In addition, the first side plate 210 and the second side plate 220 may be connected to both sides of the fixed body 100 through the connecting rod mechanism 300, and the specific arrangement may be determined according to the use requirements.

[0053] Figure 3 It is a structural schematic diagram of a hard disk fixing member provided by an embodiment of the utility model from another perspective.

[0054] Continue reading Figure 1 and Figure 2 , and also see Figure 3 In some embodiments of the present invention, a positioning portion 230 for positioning the hard disk body 500 is provided on the inner wall of at least one of the first side plate 210 and the second side plate 220. That is, the positioning portion 230 may be provided on the inner wall of the first side plate 210, the positioning portion 230 may be provided on the inner wall of the second side plate 220, or the positioning portion 230 may be provided on the inner walls of both the first side plate 210 and the second side plate 220.

[0055] The positioning portion 230 can be a protrusion or a boss integrally provided on the first side plate 210 or the second side plate 220. Accordingly, a matching portion (not shown in the figure) that cooperates with the positioning portion 230 for positioning is provided on the side wall of the hard disk body 500. When the positioning portion 230 is a protrusion or a boss, the matching portion is correspondingly a positioning hole.

[0056] Continue reading Figures 1 to 3 In some embodiments of the present invention, a shock absorbing member 400 is provided on the inner wall of at least one of the first side plate 210 and the second side plate 220, so as to improve the shock absorbing performance of the hard disk assembly. That is, the shock absorbing member 400 may be provided on the inner wall of the first side plate 210, the shock absorbing member 400 may be provided on the inner wall of the second side plate 220, or the shock absorbing member 400 may be provided on the inner walls of both the first side plate 210 and the second side plate 220.

[0057] The shock absorber 400 may be a rubber pad or a polytetrafluoroethylene pad or other elastically deformable structure, and the shock absorber 400 is fixed to the first side plate 210 or the second side plate 220 by gluing or screwing. When the hard disk body 500 is installed on the fixed main body 100, the side wall of the hard disk body 500 abuts against the shock absorber 400, and the shock absorber 400 can be used for shock absorption to prevent the hard disk body 500 from colliding with the first side plate 210 or the second side plate 220 due to vibration or shaking to cause damage.

[0058] In addition, by providing a shock absorber 400 on the inner wall of at least one of the first side plate 210 and the second side plate 220, when the hard disk body 500 is installed on the fixed main body 100, the force between the corresponding side plate and the hard disk body 500 can be increased, which can provide a certain stabilizing effect on the self-locking of the connecting rod 310.

[0059] Continue reading Figures 1 to 3 In some embodiments of the utility model, a limiting groove 240 is provided on the first side panel 210 or the second side panel 220 at a position corresponding to the shock absorber 400, and the shock absorber 400 is located in the limiting groove 240. The depth of the limiting groove 240 is adapted to the thickness of the shock absorber 400, that is, the limiting groove 240 can compensate for the thickness of the shock absorbing pad, so that the shock absorber 400 can be installed after the corresponding side panel and can remain flush with the side wall of the corresponding side panel.

[0060] In addition, when the hard disk body 500 is installed on the fixed main body 100, the hard disk body 500 can be limited by the groove wall of the limiting groove 240, which is equivalent to that the degree of freedom below the hard disk body 500 is limited by the bottom wall of the bracket 110, and the degree of freedom of the hard disk body 500 in the left and right directions is limited by the first side plate 210 and the second side plate 220. The degree of freedom of the hard disk in the front and back directions is limited by the bending structure 111 on the bracket 110 and the end plate 120 located at one end of the bracket 110. The hard disk fixing component can limit the degree of freedom of the hard disk body 500 in multiple directions, and can make the installation of the hard disk body 500 more stable.

[0061] Continue reading Figures 1 to 3 In some embodiments of the utility model, the fixed body 100 includes a bracket 110 and an end plate 120. The end plate 120 is located at the end of the bracket 110, and the end plate 120 and the bracket 110 are detachably connected by structures such as screws; the bracket 110 is used to install the hard disk body 500, and the end plate 120 is provided with a hard disk handle 130 to facilitate the disassembly and replacement of the hard disk assembly.

[0062] Continue reading Figures 1 to 3 In some embodiments of the present invention, a support portion 140 is provided on at least one of the end plate 120 and the bracket 110, that is, the support portion 140 may be provided on the end plate 120, the support portion 140 may be provided on the bracket 110, or the support portion 140 may be provided on both the end plate 120 and the bracket 110.
