Description

Technical Field

[0001] The present application relates to the technical field of hard disk installation, and in particular to a hard disk installation rack and a chassis. Background Art

[0002] Hard disk is an important device for data storage in computers. With the development of technology, the configuration requirements for computers are getting higher and higher, and accordingly, the demand for hard disk capacity is also getting higher and higher. Currently, most people use hard disk expansion to expand storage capacity, that is, to increase capacity by configuring more hard disks.

[0003] There are many ways to expand hard disks in the prior art. One is to install more hard disks in a new mounting frame when the space in the chassis allows, so as to achieve capacity expansion. Another is to remove the original hard disk mounting frame and replace and install a mounting frame that can fix multiple hard disks. Both of the above methods require cumbersome disassembly and assembly operations when expanding the hard disk capacity, which is time-consuming and labor-intensive.

[0004] Some chassis will reserve empty hard disk mounting racks during configuration to facilitate subsequent hard disk expansion.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0059] When designing and producing computer cases, the configuration of the hard drive mounting bracket will be designed accordingly according to customer needs, that is, the mounting bracket will be customized according to user needs. Generally speaking, a mounting bracket for installing a single hard drive is configured. Once user needs change and the number of hard drives needs to be increased, a new mounting bracket needs to be customized and the entire machine needs to be disassembled and replaced. This method is difficult to operate and the steps are cumbersome, time-consuming and labor-intensive for some chassis with compact internal layouts. If the user does not have a need for multiple hard drives, and a mounting bracket that can carry two or more hard drives is configured, then for application scenarios that do not require subsequent hard drive expansion, the mounting bracket will take up additional space in the chassis, which is not conducive to the compactness of the chassis layout and the miniaturization design of the product, affecting the user experience.

[0060] Based on the above problems, the present application designs a hard disk mounting rack that can be used for hard disk expansion. By setting side panels that can be rotated to open and close on both sides of the opening of the hard disk box, when only one hard disk needs to be installed, the side panels are folded to a state of closing the opening of the hard disk box, so as to achieve the purpose of not occupying additional space inside the chassis. At the same time, when a new hard disk needs to be expanded, the side panels are unfolded, and the new hard disk is fixed between the two side panels and stacked on top of the old hard disk, so that the two hard disks are tightly overlapped, so as to minimize the occupation of the internal space of the chassis by the hard disk and the hard disk mounting rack. When disassembling and installing the hard disk, you only need to simply rotate to unfold and fold the side panels, which is convenient and quick to operate.

[0061] First see Figure 1 and Figure 2 , Figure 1 The structure of the hard disk installation rack provided by the embodiment of the present application when a hard disk is installed is shown. Figure 2 The structure when two hard disks are installed is shown in FIG. Figure 1 As shown in the figure, the hard disk mounting frame 100 includes a hard disk box 110 and an extended side panel 120. The top of the hard disk box 110 has an opening 111, and the extended side panel 120 includes a first side panel 121 and a second side panel 122, and the first side panel 121 and the second side panel 122 are respectively rotatably connected to the edges of the opening 111 on opposite sides along the first horizontal direction (the direction indicated by the double arrow X in the figure).

[0062] The first side plate 121 and the second side plate 122 can be rotated to a closed state ( Figure 1 shown) or on ( Figure 2 status). Figure 2 As shown, when the first side plate 121 and the second side plate 122 are rotated to the open state, the opening 111 is opened. Figure 1 As shown, when the first side plate 121 and the second side plate 122 rotate to a closed state, at least a portion of the opening 111 is closed.

[0063] When only one hard disk 200 needs to be installed, first rotate the first side plate 121 and the second side plate 122 to Figure 2 The first hard disk 210 is then inserted into the hard disk case 110 through the opening 111, and the first side plate 121 and the second side plate 122 are rotated to the closed state. Figure 1 As shown, the first hard disk 210 is fixed in the hard disk box 110 by the first side plate 121 and the second side plate 122. After the first hard disk 210 is fixed in this way, the space occupied by the hard disk mounting frame 100 as a whole is substantially the same as the space occupied by a single hard disk box 110, so that when only one hard disk 200 is installed, no additional space in the chassis is occupied.

[0064] When two hard disks 200 are needed, after the first side plate 121 and the second side plate 122 are rotated to the open state and the first hard disk 210 is installed, the second hard disk 220 can be installed between the first side plate 121 and the second side plate 122. Figure 2 As shown, at this time, the second hard disk 220 is superimposed on the first hard disk 210. It should be noted here that the figure takes the way that a second hard disk 220 can be extended and installed between the first side plate 121 and the second side plate 122 as an example, which does not constitute a limitation on the number of extendable hard disks of the hard disk mounting rack 100. In some other embodiments, the first side plate 121 and the second side plate 122 can also be widened along the direction shown by X on the basis of the structure shown in the figure. In the closed state, the first side plate 121 and the second side plate 122 can overlap each other. In the open state, there will be a higher installation space between the widened first side plate 121 and the second side plate 122, and multiple second hard disks 220 can be stacked in this installation space.

[0065] On the basis of the above-mentioned expansion form, when only the first hard disk 210 is installed, the closed expansion side panel 120 and the side wall of the hard disk box 110 can effectively fix the first hard disk 210, but when the first hard disk 210 and the second hard disk 220 are installed at the same time, the expansion side panel 120 can no longer be closed, so the first hard disk 210 and the second hard disk 220 need to be fixed.

[0066] For the fixation of the first hard disk 210 and the second hard disk 220 after installation, please continue to refer to Figure 1 and Figure 2 The extension side plate 120 is provided with a limiting mechanism 123 for limiting the position of the hard disk 200. The limiting mechanism 123 is used to limit the position of the second hard disk 220 after the first hard disk 210 and the second hard disk 220 are installed, so that the second hard disk 220 and the first hard disk 210 located between the second hard disk 220 and the hard disk box 110 are fixed to the hard disk mounting frame 100.

[0067] Regarding the specific structure of the limiting mechanism 123, this application proposes an implementation method. Figure 1 and Figure 2 , and further combined with Figure 3The limiting mechanism 123 may include a fixed seat 1231, a limiting column 1232 and a limiting elastic member 1233. The fixed seat 1231 is arranged on the outer wall of the extended side plate 120. The limiting column 1232 is slidably penetrated in the fixed seat 1231 and can extend from the inner wall of the extended side plate 120. The limiting elastic member 1233 abuts between the fixed seat 1231 and the limiting column 1232, and is used to provide an elastic force for the limiting column 1232 to slide toward the inside of the extended side plate 120. The outward end of the limiting column 1232 protrudes from the fixing seat 1231, and the inward end of the limiting column 1232 is provided with a guiding slope 12321. When the second hard disk 220 is inserted downward, the guiding slope 12321 is squeezed by the side wall of the second hard disk 220 to cause the limiting column 1232 to shrink into the fixing seat 1231. After the second hard disk 220 is placed in place, the limiting column 1232 extends from the inner wall of the extended side panel 120 under the elastic force of the limiting elastic member 1233 and is inserted into the fixing hole 221 of the side wall of the second hard disk 220 to limit and fix the second hard disk 220.

[0068] like Figure 2 As shown in the figure, two limiting mechanisms 123 can be set on the first side panel 121 and the second side panel 122, and the upper limit columns 1232 of the two limiting mechanisms 123 protrude outward from one end of the fixing seat 1231 and are connected by a pull rod 124, so that when the second hard disk 220 is disassembled, the pull rod 124 can be pulled to make the two limiting columns 1232 on the first side panel 121 or the second side panel 122 slide outward at the same time and separate from the fixing holes 221 on the second hard disk 220, thereby facilitating the removal of the second hard disk 220.

[0069] Accordingly, in order to make the first hard disk 210 more firmly installed, Figure 2 As shown in , the same limiting mechanism 123 can also be set on the two side walls of the hard disk box 110 opposite to each other along the direction shown by X to connect with the first hard disk 210.

[0070] It is understandable that the limiting mechanism 123 can be used in addition to Figures 1 to 3 In addition to the structure shown in the figure, a pin can also be used to fix the hard disk 200 by passing the pin through the extended side panel 120 and inserting it into the fixing hole on the hard disk 200. Alternatively, a hemispherical protrusion provided on the inner wall of the extended side panel 120 can be used to squeeze the hemispherical protrusion against the side wall of the hard disk 200 to achieve the connection or separation between the hemispherical protrusion and the fixing hole on the hard disk 200, thereby achieving the installation and removal of the hard disk 200.

[0071] In summary, in the hard disk installation rack 100 provided in the embodiment of the present application, the hard disk box 110 accommodates the first hard disk 210 in a conventional manner, and rotatable extension side panels 120 are provided on both sides of the opening 111 at the top of the hard disk box 110. By folding the extension side panels 120 to close at least a portion of the opening 111, it is possible to limit and fix the first hard disk 210 when only the first hard disk 210 is installed, and at the same time, it will not occupy additional space in the chassis, which is conducive to the miniaturized design of the product. When two or more hard disks 200 need to be installed, the extension side panels 120 are unfolded so that a new hard disk 200 (i.e., the second hard disk 220) can be accommodated between the extension side panels 120, thereby realizing hard disk expansion, and ultimately achieving a redundant design while ensuring a small volume when multiple hard disks 200 do not need to be installed.

[0072] Based on this, manufacturers can provide the hard disk mounting rack 100 in the embodiment of the present application for user groups with different needs. If the user currently only needs to install a single hard disk 200, then the hard disk mounting rack 100 can not only meet the user's current needs, but also will not take up more space inside the chassis, that is, it will not cause an increase in the volume of the chassis, and when the user needs to expand the number of hard disks 200 in the future, convenient expansion can be achieved without replacing the mounting rack. If the user currently needs to install multiple hard disks 200, it only needs to open the expansion side panel 120 and install multiple hard disks 200. The operation is convenient and quick, and the multiple hard disks 200 are stacked compactly and will not take up too much space as a whole.

[0073] In addition, in order to ensure the structural stability after installing multiple hard disks 200, a limiting mechanism 123 for limiting connection with the second hard disk 220 is set on the extended side panel 120. The limiting mechanism 123 is used to limit the second hard disk 220, and the second hard disk 220 cooperates with the hard disk box 110 to limit the first hard disk 210, so that multiple hard disks 200 can be stably installed on the hard disk mounting frame 100, providing reliable protection for the operation of the hard disk 200.

[0074] Regarding the rotational connection structure between the extended side plate 120 and the hard disk box 110, this application proposes an implementation method. Figure 4 and Figure 5 , Figure 4 The structure of the hard disk mounting frame 100 is shown from a bottom perspective. It can be seen from the figure that the hard disk box 110 adopts a bottom hollow design. During the specific assembly, the bottom of the hard disk box 110 can be formed by the inner wall of the chassis, or it can be formed by the surface of the component that fixes the hard disk box 110 in the chassis. Of course, in some other embodiments, a bottom wall can also be set at the bottom of the hard disk box 110. Figure 5 The connection structure on the first side plate 121 and the second side plate 122 is shown in a manner of omitting the hard disk box 110.

[0075] like Figure 4 and Figure 5 As shown in the figure, guide grooves 113 are provided on the connecting inner walls 112 of the hard disk box 110 on opposite sides along the second horizontal direction (the direction indicated by the double arrow Y in the figure), and the guide grooves 113 are located at one end of the connecting inner wall 112 along the direction indicated by the double arrow X. It should be noted here that in the specific embodiment shown in the figure, in order to facilitate production and processing, a mounting plate 114 is installed on the connecting inner wall 112, and the guide grooves 113 are opened on the mounting plate 114, while in other embodiments, the guide grooves 113 can also be directly opened on the connecting inner wall 112.

[0076] like Figure 5 As shown in the figure, along the direction indicated by the double arrow Y, the guide groove 113 on each side includes a straight line segment 1131 and an arc segment 1132, and the straight line segment 1131 extends along the vertical direction (the direction indicated by the double arrow Z in the figure). The arc segment 1132 starts from the midpoint of the straight line segment 1131, takes the vertex of the straight line segment 1131 as the center of the circle, and extends toward the middle of the inner wall 112 in the form of a partial arc. In order to ensure that the extended side panel 120 can be fully unfolded for the hard disk 200 to be placed, the arc segment 1132 is preferably greater than or equal to 1 / 4 of a circle.

[0077] Please combine Figure 4 and Figure 5 When the first side plate 121 is in a closed state, a rotating connecting plate 130 is vertically arranged at the bottom of both ends of the first side plate 121 along the direction indicated by the double arrow Y, and a first protrusion 131 and a second protrusion 132 are arranged on the rotating connecting plate 130 at each end. The first protrusion 131 and the second protrusion 132 are arranged at intervals along the direction indicated by the double arrow Z, and the first protrusion 131 is lower than the second protrusion 132.

[0078] Please continue reading Figure 5 , and further combined with Figure 6 In the structure of the guide groove 113 from a front view, when the first protrusion 131 is located at the bottom end of the straight line segment 1131 and the second protrusion 132 is located at the midpoint of the straight line segment 1131, the first protrusion 131 and the second protrusion 132 are limited by the guide groove 113, so that the first side plate 121 is Figure 6 On this basis, when the first side plate 121 moves upward, so that the first protrusion 131 is located at the midpoint of the straight line segment 1131 and the second protrusion 132 is located at the vertex of the straight line segment 1131, the first side plate 121 can be rotated clockwise relative to the hard disk case 110 to the position as shown in the figure, with the second protrusion 132 as the axis and the first protrusion 131 moving along the arc segment 1132. Figure 7 Shown in the on state.

[0079] like Figures 4 to 7As shown in the figure, the second side plate 122 and the hard disk case 110 adopt the same connection structure as described above, except that the connection structure between the second side plate 122 and the hard disk case 110 is mirror-symmetrical to the connection structure between the first side plate 121 and the hard disk case 110. The following mainly introduces and describes the relevant structure of the first side plate 121, and the second side plate 122 is the same, so it will not be described in detail.

[0080] In this embodiment, the straight line segment 1131, the arc segment 1132 and the first protrusion 131 and the second protrusion 132 have a relative sliding and limiting cooperation relationship, so that when the extended side panel 120 is lowered and in a closed state, it cannot be directly rotated, ensuring that the extended side panel 120 can effectively fix the first hard disk 210 in the hard disk box 110. When it needs to be opened, it only needs to lift the extended side panel 120 up a certain distance before it can be easily opened, and the operation is also very convenient.

[0081] In order to facilitate the rotation operation of the extended side plate 120, a driving mechanism may be provided to drive the extended side plate 120. Figures 5 to 7 The driving mechanism 140 may include a rotating shaft 141 and a connecting rod group 142. The rotating shaft 141 is rotatably arranged on the side wall of the hard disk box 110 along the direction indicated by the double arrow Y. In the embodiment shown in the figure, the rotating shaft 141 is rotatably arranged on the mounting plate 114. The two free ends of the connecting rod group 142 are rotatably connected to the rotating shaft 141 and the position where the first protrusion 131 on the rotating connecting plate 130 is located. Specifically, the connecting rod group 142 can be directly connected between the rotating shaft 141 and the first protrusion 131, or can be connected as shown in FIG. Figures 5 to 7 As shown in the figure, the connecting rod assembly 142 is connected to the rotating shaft 141 and the position opposite to the first protrusion 131 on the other side of the rotating connecting plate 130, which is equivalent to that the connecting rod assembly 142 can be set on the inner side of the hard disk box 110 or on the outer side of the hard disk box 110.

[0082] exist Figure 6 On the basis of the state shown in the figure, when the rotating shaft 141 located on the right side of the figure rotates along the first rotation direction (counterclockwise in the figure), the first protrusion 131 is first driven by the connecting rod group 142 to move upward from the bottom end of the straight line segment 1131 to the midpoint, and the second protrusion 132 is moved upward from the midpoint of the straight line segment 1131 to the top point. At this time, the second protrusion 132 is abutted against the top end of the straight line segment 1131 and is limited. The rotating shaft 141 continues to rotate counterclockwise, and the connecting rod group 142 will drive the first protrusion 131 to move along the arc segment 1132 to drive the first side plate 121 to rotate to Figure 7 In contrast, Figure 7 Based on the state shown in the figure, the rotating shaft 141 located on the right side of the figure is rotated in the second rotation direction (clockwise in the figure), and the first side plate 121 moves in the opposite process to the above, and finally the first side plate 121 moves to Figure 6 The closed state is shown. Figure 6 and Figure 7 As for the second side plate 122 located on the left side, its movement relationship is mirror-symmetrical with the first side plate 121, which will not be described in detail here.

[0083] exist Figure 6 and Figure 7 In the specific embodiment shown, the connecting rod group 142 adopts a two-link mechanism. For this method, when the first side panel 121 is in a folded state, an angle θ1 is formed between the two connecting rods in the connecting rod group 142, and when the first side panel 121 is in an unfolded state, an angle θ2 is formed between the two connecting rods in the connecting rod group 142. Among them, θ1 should not be set too large or too small. If it is too large, θ2 will approach or be equal to 180° when the first side panel 121 is folded and retracted, so that the two connecting rods may resist each other and cause difficulty in rotation. If it is too small, it may cause the first side panel 121 to be unable to rotate and open normally. In this regard, it is preferred to adopt Figure 6 and Figure 7 The angle θ1 is 90° and the angle θ2 is 130°, which ensures that the first side panel 121 is easy and convenient to unfold and fold. The first side panel 121 is mainly used as an example for the description above, and the second side panel 122 is the same, so it will not be described in detail.

[0084] It is understandable that the connecting rod assembly 142 can be used in addition to Figure 6 and Figure 7 In addition to the two-link mechanism shown, other forms of link mechanisms may also be used as long as they can meet the mechanical transmission requirements, and the specific details are not limited here.

[0085] See also Figure 8 The figure shows the driving mechanism at the outside of the hard disk box 110. Furthermore, for the convenience of operation, the driving mechanism 140 can also include a gear 143 and a rack 144. The gear 143 is fixed to the outer end of the rotating shaft 141, and the rack 144 can be slidably connected to the hard disk box 110. The rack 144 is engaged with the gear 143. The rack 144 is used to drive the gear 143 and the rotating shaft 141 to rotate when sliding.

[0086] Please continue reading Figure 8The hard disk mounting frame 100 further includes a switch box 150, which is disposed on one side of the hard disk box 110 and covers the gear 143 and the rack 144. The driving mechanism 140 further includes a lever 145 located in the switch box 150, one end of the lever 145 is fixedly connected to the rack 144, and the other end protrudes from the outer wall of the switch box 150 to form a force-bearing end 1451. A guide hole 151 for the lever 145 to move is provided on the switch box 150. The user can apply a thrust to the force-bearing end 1451 by hand or a tool, so that when the lever 145 moves along the guide hole 151, the first side plate 121 is driven to rotate through the transmission of the rack 144, the gear 143, the rotating shaft 141 and the connecting rod group 142 in sequence, thereby completing the opening or closing operation of the first side plate 121.

[0087] Similarly, the second side plate 122 may be driven by the same driving mechanism 140 as described above, and the driving mechanism 140 for driving the second side plate 122 may be arranged in a mirror-symmetrical manner to the driving mechanism 140 for driving the first side plate 121 .

[0088] In order to prevent the first side plate 121 from being opened or closed by mistake due to the accidental touching of the lever 145, a switch mechanism 160 may be provided to lock the first side plate 121. Figure 8 , and further combined with Fig. 9 , Figure 8 The middle is the state when the switch mechanism 160 locks the drive mechanism 140, Fig. 9 This is the state when the switch mechanism 160 unlocks the driving mechanism 140. As shown in the figure, a snap-fitting portion 1441 is provided on the rack 144, and the switch mechanism 160 includes a locking member 161 movably connected to the switch box 150. The locking member 161 can be a rotating structure, a sliding structure, etc., and the rack 144 is locked and unlocked by moving to a state of being engaged with or separated from the snap-fitting portion 1441.

[0089] like Figure 8 As shown in , when the first side plate 121 is in the closed state shown in the figure, the locking member 161 is engaged with the engaging portion 1441 to restrict the rack 144 from sliding, thereby locking the first side plate 121. At this time, the lever 145 will not move even if it is accidentally touched. Fig. 9 As shown in FIG, when the locking member 161 moves and separates from the engaging portion 1441, the sliding restriction on the rack 144 is released, and the rack 144 can be driven to slide normally by the lever 145 to realize the opening or closing operation of the first side plate 121. The second side plate 122 can be locked in the same manner, and the switch mechanism 160 for locking the second side plate 122 is arranged in a mirror-symmetrical manner with the switch mechanism 160 for locking the first side plate 121.

[0090] Regarding the specific structure of the locking member 161, this application proposes an implementation method, please continue to refer to Figure 8 and Fig. 9 The locking member 161 includes a first section 1611 and a second section 1612 which are angled with each other, and a locking portion 16111 is provided at the free end of the first section 1611 for engaging or disengaging with the engaging portion 1441. The adjacent portion between the first section 1611 and the second section 1612 (i.e., the corner between the first section 1611 and the second section 1612) is rotatably connected to the switch box 150. A button block 162 is embedded in the switch box 150, and the button block 162 is movably connected to the free end of the second section 1612, which may be a rotatable connection or a movable limit connection as shown in the figure. After the second side panel 122 adopts the locking member 161 of the same structure and is arranged in a mirror-symmetrical manner, the two locking members 161 can share the same button block 162, that is, Figure 8 and Fig. 9 As shown, the free ends of the two second sections 1612 are movably connected to the two sides of the button block 162 respectively.

[0091] A resetting elastic member 163 is connected between the button block 162 and the hard disk box 110, and the resetting elastic member 163 is used to provide a way for the button block 162 to be turned outward (ie, to be connected to the hard disk box 110). Fig. 9 The resetting elastic member 163 can be used in addition to the elastic force of the middle button block 162 in the opposite direction of the dotted arrow. Figure 8 and Fig. 9 In addition to the compression spring connected between the button block 162 and the hard disk box 110 as shown, a compression spring, a spring sheet, etc. connected between the button block 162 and the switch box 150 can also be used, or a torsion spring mounted on the rotating shaft at the corner of the locking member 161 can also be used. The specific method is not limited here, as long as it can provide a reset elastic force to the button block 162 or the locking member 161.

[0092] Combination Figure 8 and Fig. 9 ,exist Figure 8 In the state where the locking portion 16111 is engaged with the engaging portion 1441, the resetting elastic member 163 can provide elastic force to reliably engage the locking member 161 with the engaging portion 1441, thereby ensuring the reliability of locking the extended side plate 120. Figure 8 Based on the status shown, along Fig. 9 When the button block 162 is pressed inward in the direction indicated by the dashed arrow at the middle button block 162, the button block 162 will Fig. 9 As shown, the locking member 161 is driven to rotate relative to the switch box 150 to separate the locking portion 16111 from the engaging portion 1441, thereby releasing the sliding restriction on the rack 144. The unlocking operation is convenient and quick, and when the button block 162 is no longer under pressure, the button block 162 and the locking member 161 will automatically reset under the drive of the reset elastic member 163.

[0093] See also Fig.10 The figure shows the structure of the switch mechanism 160 when the extended side panel 120 is in the open state. In this state, the two facing surfaces between the locking portion 16111 and the engaging portion 1441 can be arc surfaces as shown in the figure, or can be inclined surfaces. When the rack 144 slides in the direction indicated by the dotted arrow in the figure and drives the first side panel 121 to rotate from the open state to the closed state, the two facing surfaces between the locking portion 16111 and the engaging portion 1441 will abut against each other and frictionally cooperate to push the locking member 161 to overcome the elastic force of the reset elastic member 163 and rotate. In this process, the engaging portion 1441 crosses the locking portion 16111 and reaches the other side of the locking portion 16111. Then the locking portion 16111 will be reset under the elastic force of the reset elastic member 163. Finally, the engaging portion 1441 and the locking portion 16111 form a Figure 8 The limit locking state shown in .

[0094] For ease of operation, Figure 8 and Fig. 9 As shown, two racks 144 that are transmission-connected to the first side plate 121 and the second side plate 122 can respectively drive the first side plate 121 and the second side plate 122 to rotate to an open state when sliding away from each other. The hard disk case 110 can be provided with a driving elastic member 146, which is used to provide elastic force for the two racks 144 to slide away from each other. Specifically, the driving elastic member 146 can be as follows Figure 8 and Fig. 9 As shown, two driving elastic members 146 are provided and respectively abut between the hard disk box 110 and the two racks 144 . Alternatively, only one driving elastic member 146 may be provided and abut between the two facing surfaces of the two racks 144 .

[0095] With the above settings, Figure 8In the closed state shown, after pressing the button block 162, the rack 144 is unlocked and slides automatically under the elastic force of the driving elastic member 146, and then drives the extended side panel 120 to automatically rotate and open through the gear 143, the rotating shaft 141 and the connecting rod assembly 142. When it is necessary to close the extended side panel 120, only two fingers are needed from the outside of the switch box 150 to press against the two force-bearing ends 1451 respectively and move them close to each other, so that the extended side panel 120 can be closed and locked. Specifically, the two force-bearing ends 1451 approach each other to make the two racks 144 slide toward each other, and when the engaging portion 1441 and the locking portion 16111 are released, the engaging portion 1441 can easily reach the other side of the locking portion 16111 through the friction cooperation of the arc surface or the inclined surface without manually pressing the button block 162, and after the engaging portion 1441 reaches the other side of the locking portion 16111, the locking portion 16111 automatically resets under the elastic force of the reset elastic member 163, thereby realizing the clamping limit of the engaging portion 1441.

[0096] Most of the current hard disk enclosures are fixed to the hard disk mounting frame on the chassis wall by screws. When disassembling and assembling, auxiliary tools such as screwdrivers are required, which is cumbersome and inefficient. In this regard, the present application also makes relevant designs for the installation and fixation of the hard disk enclosure 110. For details, please refer to Figures 11 to 14 ,like Fig.11 As shown in the overall structure of FIG, the hard disk mounting frame 100 further includes a bearing platform 170. The bearing platform 170 may be an independent bracket as shown in the figure, or may be directly formed by the inner wall of the chassis body. Both the hard disk box 110 and the switch box 150 may be detachably arranged on the bearing platform 170, and both the hard disk box 110 and the switch box 150 have a bottom plate (such as Fig.13 and Fig.14 The cross-sectional structure at two sections in Fig. Fig.12 and Fig.13 As shown in FIG. 1 , a fixing column 171 is disposed on the carrier 170, and the end of the fixing column 171 has a clamping joint 172 with an increased radial dimension. Specifically, the fixing column 171 can be Fig.13 The head of the top end of the I-shaped nail shown in FIG. 1 forms a clamping joint 172.

[0097] like Fig.13 As shown, the two bottom plates 180 are arranged in contact with each other at the side, and the two sides facing each other between the two bottom plates 180 are respectively provided with a first notch 181 and a second notch 182 (see Figure 4 The first notch 181 and the second notch 182 are respectively sleeved on the fixing column 171 from both sides and are together surrounded by the outer circumference of the fixing column 171. The two bottom plates 180 are respectively positioned at the portions around the first notch 181 and the second notch 182 along the circumference of the fixing column 171, so that the first notch 181 and the second notch 182 are respectively sleeved on the fixing column 171, and are together surrounded by the outer circumference of the fixing column 171. Fig.13 From the perspective, the hard disk box 110 and the switch box 150 are fixed relative to the supporting platform 170 in the vertical direction.

[0098] like Fig.14 As shown, a first limiting member 115 is provided on the hard disk box 110, and a second limiting member 152 is provided on the switch box 150. The first limiting member 115 and the second limiting member 152 are detachably connected to each other, and when the first limiting member 115 and the second limiting member 152 are connected, the hard disk box 110 and the switch box 150 can be limited to move away from each other, that is, when Fig.14 From the perspective, the hard disk box 110 is restricted from moving to the left, and the switch box 150 is restricted from moving to the right.

[0099] In summary, based on the restriction of the upper and lower directions of the hard disk box 110 and the switch box 150 by the card connector 172, and the restriction of the movement of the hard disk box 110 and the switch box 150 in opposite directions by the first limiter 115 and the second limiter 152, the hard disk box 110 and the switch box 150 are reliably fixed on the support platform 170. And during assembly, it is only necessary to align the first notch 181 and the second notch 182 with the fixing column 171 respectively, and then put them on the fixing column 171 from both sides, and finally connect the first limiter 115 with the second limiter 152, so that the hard disk box 110 and the switch box 150 can be assembled and fixed on the support platform 170, and the whole process is easy and convenient. When disassembling, the reverse operation can be performed, which is also convenient and quick.

[0100] If the fixing column 171 is cylindrical, then after the assembly is completed, considering that the single-point limit will cause the hard disk box 110 and the switch box 150 to rotate together on the support platform 170, for this purpose, a plurality of fixing columns 171 can be provided on the support platform 170, and the two bottom plates 180 are respectively provided with a first notch 181 and a second notch 182, thereby forming a multi-point limit to solve the rotation problem.

[0101] Regarding the specific matching form of the first stopper 115 and the second stopper 152, this application proposes an implementation scheme. Fig.15, the figure shows the exploded structure of the first limiting member 115 and the second limiting member 152. As shown in the figure, the first limiting member 115 includes a connecting block 1151 arranged on the hard disk box 110 toward the switch box side, and a limiting slot 1152 is provided on the connecting block 1151. The second limiting member 152 includes a limiting shaft 1521 that penetrates the wall of the switch box 150 and is slidably arranged. Specifically, a through hole 153 is provided on the wall of the switch box 150, and the limiting shaft 1521 is slidably arranged in the through hole 153. After the switch box 150 and the hard disk box 110 are attached to each other, the switch box 150 covers the connecting block 1151, and the limiting shaft 1521 is used to slide in the inward direction (i.e., the direction toward the inside of the switch box 150) and snap into the limiting slot 1152, so that the hard disk box 110 and the switch box 150 are mutually limited and fixed, as shown in the figure. Fig.14 The status shown. Fig.14 On the basis, the limiting shaft 1521 is used to move in an outward direction (ie, a direction toward the outside of the switch box 150, Fig.14 After the hard disk box 110 and the switch box 150 are slid upward from the viewing angle and separated from the limiting groove 1152, the limiting of the hard disk box 110 and the switch box 150 is released. It can be seen that when disassembling and assembling the hard disk box 110 and the switch box 150 on the supporting platform 170, it is only necessary to operate the limiting shaft 1521 and move the hard disk box 110 and the switch box 150, and the disassembly and assembly process is convenient and fast.

[0102] Please continue reading Fig.15 , and further combined with Fig.16 , Fig.16 The cross-sectional structure of the limit shaft 1521 is shown. As shown in the figure, an elastic member 1522 may be connected between the portion of the limit shaft 1521 located inside the switch box 150 and the inner wall of the switch box 150. The elastic member 1522 is used to provide elastic force for the limit shaft 1521 to slide inward. A force-bearing portion 1523 may be provided at one end of the limit shaft 1521 located outside the switch box. When not subjected to an upward pulling force, the force-bearing portion 1523 abuts against the outer surface of the switch box 150 to limit the maximum travel of the limit shaft 1521 sliding inward. The force-bearing portion 1523 is used to drive the limit shaft 1521 to slide in the outward direction when subjected to an outward pulling force, so that the limit shaft 1521 is disengaged from the limit slot 1152, thereby realizing the limit unlocking of the switch box 150 and the hard disk box 110. Specifically, after the elastic member 1522 is sleeved on the limiting shaft 1521 , it can penetrate the switch box 150 from the inside to the outside, and the end that passes out to the outside is threadedly connected and fixed to the force-bearing part 1523 to achieve the installation of the limiting shaft 1521 on the switch box 150 .

[0103] like Fig.16As shown, the end face 15211 on the limit shaft 1521 located in the switch box 150 can be set to an inclined surface or an arc surface, so that when the switch box 150 and the hard disk box 110 move toward each other for fitting, the end face 15211 abuts against the connecting block 1151 and is squeezed by the connecting block 1151 to make the limit shaft 1521 slide in the outward direction. When the end face 1521 is aligned with the limit groove 1152, the limit shaft 1521 slides in the inward direction under the elastic force of the elastic member 1522 and is stuck into the limit groove 1152. In this way, when the hard disk box 110 and the switch box 150 are connected, there is no need to manually operate the limit shaft 1521. The hard disk box 110 and the switch box 150 only need to be moved toward each other to complete the fixation of the two on the supporting platform 170, and the operation is more convenient and quick.

[0104] According to another aspect of the embodiment of the present application, a chassis is also provided. Fig.17 , the figure shows the structure of the chassis, the chassis 400 includes a box body 300 and a hard disk mounting bracket 100 provided in any of the above embodiments, and the hard disk mounting bracket 100 is arranged in the box body 300.

[0105] By adopting the hard disk mounting bracket 100 provided in the above embodiment, when only one hard disk is installed in the chassis 400, the hard disk mounting bracket 100 will not occupy additional space of the box body 300, which is conducive to the miniaturized design of the product. When two or more hard disks need to be installed, the hard disk can be conveniently expanded by unfolding the extension side panel 120.

[0106] Furthermore, in order to facilitate the disassembly and assembly of the hard disk, Fig.17 and 18 As shown in the figure, a disassembly opening 310 can be opened on the box 300 to realize convenient disassembly and expansion of the hard disk 200. An openable cover 320 is provided on the disassembly opening 310. The cover 320 closes the disassembly opening 310 when there is no need to disassemble the hard disk 200 to protect the internal space of the box 300.

[0107] According to another aspect of the embodiment of the present application, a computer is also provided. Fig.17 and Fig.18 The computer 500 includes the chassis 400 provided by any of the above embodiments.
