[0002] In the Internet era, as a core component of Internet infrastructure, servers in the data center system need to run stably for a long time. Especially during operation and maintenance, it is also required that the server runs stably without power interruption. Hard disk brackets usually support the hot plug function, and hard disks can be safely inserted or removed while the server is running. Therefore, hard disk brackets are usually installed in the server to fix the hard disks, ensuring that the hard disks can be firmly installed in the server chassis, and when performing operation and maintenance on the hard disks, the server can continue to run stably.

[0003] However, the existing method of assembling hard disks is to lock the hard disks on the hard disk brackets with four to six screws. When performing operation and maintenance on the hard disks, it takes a lot of time to disassemble and assemble the screws, and the screws may even fall into the server during the disassembly and assembly process, which may even affect the normal operation of the server. Summary of the Utility Model

[0007] In an optional manner, the bracket body includes a base plate, which is located at the bottom of the installation cavity and is used to support the hard disk. When the limiting member is in the second state, the distance between the bottom end of the abutting portion and the base plate is greater than the height of the hard disk.

[0010] In an optional manner, a limiting protrusion is provided at one end of the rotating shaft away from the rotating part, and the limiting protrusion passes through the connecting hole and is clamped with the hole surface of the connecting hole away from the installation cavity.

[0011] In an optional manner, one end of the rotating shaft away from the rotating part is decomposed into multiple parts, and there are gaps between the multiple parts; the limiting protrusion has a second inclined surface, and the second inclined surface is used to abut against the inner wall of the connecting hole when the rotating shaft passes through the connecting hole in a direction away from the installation cavity, so that the multiple parts are close to each other, and then the end of the rotating shaft away from the rotating part passes through the connecting hole.

[0012] In an optional manner, the clamping member includes an elastic member and a clamping portion, one end of the elastic member is connected to the side wall of the bracket body, and the other end is connected to the clamping portion, and the first inclined surface is arranged on the clamping portion; the elastic member is used to deform when the clamping portion moves in a direction away from the hard disk and provide a restoring elastic force to the clamping portion, so that the clamping portion is reset when the hard disk is inserted into a predetermined position and the hard disk is fixed in the predetermined position.

[0013] In an optional manner, a avoidance hole is provided on the side wall of the bracket body adjacent to the opening, the elastic member is a spring sheet extending from the edge of the avoidance hole to the inside of the avoidance hole, the clamping portion is arranged on the side of the spring sheet facing the installation cavity, and the spring sheet is used to deform as the clamping portion moves in a direction away from the hard disk to provide a reset elastic force to the clamping portion.

[0014] According to another aspect of an embodiment of the present application, there is provided an electronic device comprising any of the hard disk brackets described above.

[0015] The embodiment of the present application sets a clamping member and sets a first inclined surface on the clamping member, so that when the hard disk enters the installation cavity from the opening, it will abut against the first inclined surface, so that the clamping member moves in the direction away from the hard disk and resets when the hard disk is inserted into the predetermined position to clamp with the hard disk, thereby fixing the hard disk on the hard disk bracket, and there is no need to use tools such as screwdrivers and screws to fix the hard disk, and the installation of the hard disk is more convenient. In addition, a limiter is also set, and the hard disk is limited to a predetermined position by setting the limiter in a first state, so that the clamping member is clamped with the hard disk, and then the hard disk is fixed on the hard disk bracket; the limiter is set in a second state to release the space in the installation cavity, so that the hard disk can continue to move into the installation cavity, so as to separate the hard disk from the clamping member, and then remove the hard disk from the hard disk bracket, without using tools such as screwdrivers, and there is no need for the user to manually bend the clamping member to separate the clamping member and the hard disk, and the removal of the hard disk is also more convenient.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements.

[0049] A hard disk tray is a component inside an electronic device used to install and fix a hard disk. It can ensure that the hard disk remains stable inside the server chassis, reducing the risk of failure due to vibration or poor contact. Especially in a server, the hard disk tray usually supports the hot plug function, allowing the hard disk to be safely inserted or removed while the server is running, facilitating hard disk replacement, expansion, or maintenance, and reducing downtime and maintenance costs.

[0050] The inventors of the present application noticed that existing hard disks are usually fixed to the hard disk tray with screws. When assembling the hard disk and the hard disk tray, it is necessary to first align the screw holes on the hard disk with the screw holes on the hard disk tray one by one, and then use a screwdriver to pass one end of the screw through the screw hole of the hard disk tray and tighten it into the screw hole on the hard disk, thereby fixing the hard disk to the hard disk tray. When disassembling the hard disk, it is necessary to use a screwdriver to remove all the screws on the hard disk tray and then remove the hard disk from the hard disk tray. The process of assembling and disassembling the hard disk is complex and time-consuming, and the screws may also fall into the server chassis during the assembling and disassembling process, thus affecting the normal operation of the server.

[0051] Therefore, in order to solve the problem of the complex process of assembling and disassembling a hard disk, the inventors of the present application have conducted in-depth research and designed a hard disk bracket. The hard disk bracket is formed with an installation cavity for installing a hard disk. An opening for the hard disk to enter is provided on one side of the installation cavity. A clamping member is provided on the side wall adjacent to the opening. One end of the clamping member facing the installation cavity has an inclined surface facing the opening. When the hard disk enters the installation cavity from the opening, it will abut against the inclined surface on the clamping member, causing the clamping member to move in a direction away from the hard disk and reset and engage with the hard disk when the hard disk is inserted to a predetermined position, so that the hard disk can be fixed on the hard disk bracket. The installation of the hard disk is simple and convenient, and tools such as screws and screwdrivers are not required, reducing the time for removing screws.

[0052] In addition, in order to ensure the stability of the hard disk, after the clamping member engages with the hard disk, the clamping member will restrict the movement of the hard disk towards the outside of the installation cavity, that is, the hard disk cannot directly move out of the installation cavity from the opening. This results in the need for the user to manually separate the clamping member from the hard disk when disassembling the hard disk in order to move the hard disk out of the installation cavity, and the disassembly of the hard disk is relatively troublesome. However, the inventors of the present application have noticed that because the inclined surface is provided on the clamping member, after the clamping member engages with the hard disk, if the hard disk is further moved towards the inside of the installation cavity, the hard disk will continue to abut against the clamping member, causing the clamping member to move in a direction away from the hard disk. If the hard disk is moved beyond the predetermined position, the clamping member will no longer be able to engage with the hard disk, and at this time, the hard disk can be moved out of the installation cavity.

[0053] Therefore, a limiting member is also movably provided on the side wall of the installation cavity opposite to the opening. When installing the hard disk, at least part of the limiting member is moved into the installation cavity, so that the hard disk will abut against the limiting member when entering the installation cavity, and then be restricted to be engaged with the clamping member at a predetermined position to fix the hard disk on the hard disk bracket. When disassembling the hard disk, control the movement of the limiting member and release at least part of the space in the installation cavity occupied by it, so that the hard disk can continue to move towards the inside of the installation cavity and abut against the inclined surface on the clamping member, causing the clamping member to move in a direction away from the hard disk and separate from the hard disk, and the hard disk can be disassembled from the hard disk bracket.

[0054] Such a design enables the hard disk to be separated from the clamping member by simply adjusting the limiting member to the second state and then moving the hard disk further towards the inside of the installation cavity when disassembling the hard disk, without the need to use tools such as a screwdriver to remove screws, nor the need for the user to manually separate the clamping member from the hard disk. The disassembly of the hard disk is simpler and more convenient, improving the maintainability and working efficiency of the hard disk in the electronic device and effectively reducing the operation and maintenance time.

[0055] In addition to being used to fix the hard disk, the hard disk bracket in the embodiments of the present application can also be used to fix devices with similar fixing methods such as hard disk drives, hard disk enclosures, and optical drives. Only the hard disk is taken as an example for illustration in the embodiments of the present application.

[0056] Please refer to Figure 1 , Figure 1 which shows a partial structural diagram of an electronic device provided by an embodiment of the present utility model. The hard disk bracket 1000 provides an appropriate installation space for the hard disk 2000. Fixing the hard disk 2000 on the hard disk bracket 1000 and then installing the hard disk 2000 into the electronic device can ensure that the hard disk 2000 is firmly installed in the device. As Figure 1 shown, the hard disk bracket 1000 includes a bracket body 100. An opening 110 is formed on one side of the bracket body 100. The hard disk 2000 enters the installation space provided by the hard disk bracket 1000 through the opening 110, and then the hard disk 2000 is fixed on the hard disk bracket 1000 through the side adjacent to the opening 110 on the bracket body 100. Finally, it is fixed in the electronic device through the hard disk bracket 1000.

[0057] According to one aspect of the embodiments of the present application, a hard disk bracket is provided. As Figure 1 and Figure 2 shown,[[]] Figure 2 which shows a perspective view of the hard disk bracket provided by an embodiment of the present utility model. The hard disk bracket 1000 includes a bracket body 100. The bracket body 100 has side walls, and an installation cavity 200 is formed between the side walls. The installation cavity 200 is used to accommodate the hard disk 2000. An opening 110 is formed on one side of the installation cavity 200. The opening 110 is used for the hard disk 2000 to enter the installation cavity 200. A clamping member 210 is provided on the side wall of the bracket body 100 adjacent to the opening 110. One end of the clamping member 210 facing the installation cavity 200 has a first inclined surface 220. The first inclined surface 220 faces the opening 110. The first inclined surface 220 is used to be abutted by the hard disk 2000 when the hard disk 2000 enters the installation cavity 200 from the opening 110, so that the clamping member 210 moves in a direction away from the hard disk 2000. The clamping member 210 is used to reset and engage with the hard disk 2000 when the hard disk 2000 is inserted to a predetermined position. A limiting member 300 is movably provided on the side wall of the bracket body 100 opposite to the opening 110. The limiting member 300 has a first state and a second state. When the limiting member 300 is in the first state, at least part of it is located in the installation cavity 200 and is used to abut against the inner side of the hard disk 2000 when the hard disk 2000 enters the installation cavity 200 to limit the hard disk 2000 to a predetermined position. The limiting member 300 is also used to release at least part of the space in the installation cavity 200 occupied when in the second state, so that the hard disk 2000 can continue to move inward into the installation cavity 200 and abut against the first inclined surface 220, causing the clamping member 210 to move in a direction away from the hard disk 2000 and separate from the hard disk 2000, so as to remove the hard disk 2000 from the installation cavity 200.

[0058] The bracket body 100 is the main structure of the hard disk bracket 1000. As Figure 2As shown in the figure, the side and the bottom plate 140 of the bracket body 100 together form an installation cavity 200, that is, the space surrounded by the side walls of the bracket body 100 is the installation cavity 200. An opening 110 communicating with the installation cavity 200 is provided on one side of the bracket body 100, that is, the opening 110 provided on one side of the installation cavity 200. The position on the right side of the bracket body 100 where no side wall is provided is the entrance for installing the hard disk 2000 on the hard disk bracket 1000, that is, the opening 110 for the hard disk 2000 to enter the installation cavity 200. When installing the hard disk 2000, the hard disk 2000 can be pushed into the installation cavity 200 from the opening 110 to the left. Of course, the opening 110 can also be a notch provided on the side wall of the bracket body 100, that is, a part of the side wall is also provided on the side of the bracket body 100 where the opening 110 is located.

[0059] The clamping member 210 can be arranged opposite to the fixing holes on the hard disk 2000 (for example, as Figure 2 shown, two clamping members 210 are respectively arranged on the two side walls adjacent to the opening 110 of the installation cavity 200 to be clamped with the four fixing holes on the hard disk 2000), and when the hard disk 2000 reaches the predetermined position, it is inserted into the fixing holes on the hard disk 2000 to fix the hard disk 2000. The clamping member 210 can also be arranged at a position on the side wall close to the opening 110. When the hard disk 2000 is inserted to the predetermined position, after the clamping member 210 is reset, it is clamped with one end of the hard disk 2000 facing the opening 110 (that is, the tail end of the hard disk 2000) to abut the hard disk 2000 between the limiting member 300 and the clamping member 210. When the clamping member 210 fixes the hard disk 2000 by clamping with the fixing holes on the hard disk 2000, after the hard disk 2000 enters the installation cavity 200, the position where the hard disk 2000 is located when the fixing holes on the hard disk 2000 are opposite to the clamping member 210 is the predetermined position; when the clamping member 210 fixes the hard disk 2000 by clamping with the tail end of the hard disk 2000, after the hard disk 2000 enters the installation cavity 200, the position where the tail end of the hard disk 2000 just abuts against the clamping member 210 is the predetermined position.

[0060] As Figure 2 shown, an avoidance hole 150 can be provided on the side wall of the bracket body 100, and the clamping member 210 is arranged in the avoidance hole 150 and extends into the installation cavity 200. When the opening 110 is provided on the right side of the installation cavity 200, one end of the clamping member 210 facing the installation cavity 200 has a first inclined surface 220, and the first inclined surface 220 faces the right side of the bracket body 100. When the hard disk 2000 is pushed into the installation cavity 200 from the right side of the hard disk bracket 1000 to the left, the hard disk 2000 will abut against the first inclined surface 220 and squeeze the clamping member 210 to move towards the outside of the installation cavity 200. When the hard disk 2000 is inserted to the predetermined position, as Figure 3 shown, Figure 3The structural schematic diagram of the first state of the limiting member provided by the embodiment of the present utility model is shown. That is, when the fixing hole 2100 on the hard disk 2000 is opposite to the clamping member 210, the first inclined surface 220 is no longer extruded by the hard disk 2000, and the clamping member 210 will automatically reset. And the end of the clamping member 210 facing the installation cavity 200 will be inserted into the fixing hole 2100 on the hard disk 2000 to fix the hard disk 2000 on the hard disk bracket 1000. The first inclined surface 220 can be a curved surface in addition to being a flat surface.

[0061] Since the first inclined surface 220 faces the opening 110, the hard disk 2000 will only abut against the first inclined surface 220 and cause the clamping member 210 to move when the hard disk 2000 enters the installation cavity 200 from the opening 110. When the clamping member 210 is clamped with the hard disk 2000, the hard disk 2000 can only continue to move towards the inside of the installation cavity 200 and cannot move in other directions, thereby fixing the hard disk 2000 on the hard disk bracket 1000. If the hard disk 2000 needs to be disassembled, the clamping member 210 needs to be separated from the hard disk 2000. Therefore, as Figure 2 shown, a limiting member 300 is also movably arranged on the side wall of the left side of the bracket body 100. When installing the hard disk 2000, the limiting member 300 is placed in the first state so that the hard disk 2000 is restricted at a predetermined position and clamped with the clamping member 210. When disassembling the hard disk 2000, the limiting member 300 is placed in the second state to release at least part of the space of the installation cavity 200 occupied, so that the hard disk 2000 can continue to move towards the inside of the installation cavity 200 and be separated from the clamping member 210.

[0062] As Figure 2 shown, a connection hole can be opened on the side wall of the bracket body 100, and the rotating shaft on the limiting member 300 is inserted into the connection hole so that the limiting member 300 is rotatably connected to the side wall of the bracket body 100. Of course, a rotating shaft can also be provided on the side wall of the bracket body 100 and a connection hole can be provided on the limiting member 300. As Figure 3 and Figure 4 shown, Figure 4 The another structural schematic diagram of the first state of the limiting member provided by the embodiment of the present utility model is shown. When installing the hard disk 2000, the limiting member 300 is rotated to the Figure 3 state shown in Figure 4 so that the limiting member 300 occupies the space along the insertion direction of the hard disk 2000 in the installation cavity 200. When the hard disk 2000 is inserted to a predetermined position in the installation cavity 200, the inner side of the hard disk 2000 will abut against the limiting member 300, so that the hard disk 2000 cannot continue to move towards the inside of the installation cavity 200. At this time, the hard disk 2000 will be clamped with the clamping member 210 (that is, as

[0063] When disassembling the hard disk 2000, as Figure 5 and Figure 6 shown, Figure 5 Fig. shows a schematic structural diagram of the second state of the limiting member provided by the embodiment of the present utility model, Figure 6 Fig. shows another schematic structural diagram of the second state of the limiting member provided by the embodiment of the present utility model. Rotate the limiting member 300 to the state shown in Figure 5 so that the limiting member 300 releases at least part of the space along the insertion direction of the hard disk 2000 in the installation cavity 200 it occupies, making the distance between the hard disk 2000 and the side wall of the bracket body 100 large enough, and the hard disk 2000 can continue to move inward into the installation cavity 200 to separate from the clamping member 210 (that is, as shown in Figure 6 shown, the clamping member 210 is misaligned with the fixing hole 2100 of the hard disk 2000), and then the hard disk 2000 is removed from the installation cavity 200.

[0064] Of course, as Figure 7 shown, Figure 7 Fig. shows another perspective view of the hard disk bracket provided by the embodiment of the present utility model. The clamping member 210 can also be arranged in the installation cavity 200. One end of the clamping member 210 is fixedly connected to the side wall of the bracket body 100, and the first inclined surface 220 is arranged at one end of the clamping member 210 facing away from the side wall of the bracket body 100. When the hard disk 2000 is pushed into the installation cavity 200 from the right side to the left side of the hard disk bracket 1000, the hard disk 2000 will abut against the first inclined surface 220 and push the clamping member 210 against the side wall of the bracket body 100, making the clamping member 210 approach the side wall of the bracket body 100. When the hard disk 2000 reaches the predetermined position, the clamping member 210 will automatically reset and be clamped with the hard disk 2000, and then the hard disk 2000 is fixed on the hard disk bracket 1000.

[0065] In addition, as Figure 7 shown, a slide rail 120 can also be arranged on the side wall of the bracket body 100, and the limiting member 300 is slidably connected to the slide rail 120. The position of the limiting member 300 is adjusted by sliding. When installing the hard disk 2000, slide the limiting member 300 downward into the installation cavity 200 so that the hard disk 2000 abuts against the limiting member 300 when entering the installation cavity 200 to limit the hard disk 2000 at the predetermined position. When disassembling the hard disk 2000, slide the limiting member 300 upward out of the installation cavity 200 to release the space of the installation cavity 200 occupied by the limiting member 300.

[0066] It should be particularly noted that, in addition to the above several setting methods, there are also various different setting methods for the limiting member 300. For example, the limiting member 300 is set as a retractable member. In the first state, it extends into the installation cavity 200, and in the second state, it retracts outside the installation cavity 200, etc. When setting the limiting member 300, the optimal setting method can be adopted according to actual needs, as long as it is ensured that the limiting member 300 can limit the hard disk 2000 at a predetermined position in the first state, so that the clamping member 210 is clamped with the hard disk 2000, and in the second state, it can release at least part of the space in the occupied installation cavity 200, so that the hard disk 2000 can continue to move inward into the installation cavity 200 to separate from the clamping member 210. In addition, various setting methods of the limiting member 300 and various setting methods of the clamping member 210 can be randomly combined. For example, the clamping member 210 is arranged in the avoidance hole on the side wall of the bracket body 100 (i.e., as shown in Figure 2 ), and the limiting member 300 is movably connected to the side wall of the bracket body 100 through a slide rail (i.e., as shown in Figure 7 ).

[0067] When installing the hard disk 2000, the limiting member 300 is set in the first state, and then the hard disk 2000 is pushed into the installation cavity 200 from the opening 110, so that the hard disk 2000 is pushed to a predetermined position and clamped with the clamping member 210. When disassembling the hard disk 2000, as shown in Figure 8 , Figure 8 shows the disassembly schematic diagram of the hard disk provided by the embodiment of the present invention. After continuing to push the hard disk 2000 inward into the installation cavity 200 so that the hard disk 2000 is separated from the clamping member 210, move the tail end of the hard disk 2000 upward by a certain distance, and then hold the tail end of the hard disk 2000 and pull the hard disk 2000 out of the installation cavity 200.

[0068] The above-mentioned embodiment sets a clamping component 210 and sets a first inclined surface 220 on the clamping component 210, so that when the hard disk 2000 enters the installation cavity 200 from the opening 110, it will abut the first inclined surface 220, so that the clamping component 210 moves in the direction away from the hard disk 2000 and resets to engage with the hard disk 2000 when the hard disk 2000 is inserted into the predetermined position, thereby fixing the hard disk 2000 on the hard disk bracket 1000. There is no need to use tools such as screwdrivers and screws to fix the hard disk 2000, and the installation of the hard disk 2000 is more convenient. In addition, a limit member 300 is provided, and the hard disk 2000 is limited to a predetermined position by setting the limit member 300 in a first state, so that the snap-in member 210 is snapped with the hard disk 2000, thereby fixing the hard disk 2000 on the hard disk bracket 1000; the limit member 300 is set in a second state to release the space in the installation cavity 200, so that the hard disk 2000 continues to move into the installation cavity 200, so as to separate the hard disk 2000 from the snap-in member 210, and then remove the hard disk 2000 from the hard disk bracket 1000, without using tools such as screwdrivers, and without the user having to manually pry the snap-in member 210 to separate the snap-in member 210 and the hard disk 2000, and the removal of the hard disk 2000 is also more convenient.

[0069] In order to make the structure of the hard disk bracket simpler, in some embodiments of the present application, such as Figure 2 , Figure 3 and Figure 5 As shown, the stopper 300 includes a rotating portion 310, one end of the rotating portion 310 is rotatably connected to a connection point 130 on the side wall of the bracket body 100, and the distance between the connection point 130 and the bottom of the mounting cavity 200 is smaller than the height of the hard disk 2000. An abutment portion 320 is provided at one end of the rotating portion 310 away from the connection point 130, and the dimension of the abutment portion 320 along the insertion direction of the hard disk 2000 is larger than the dimension of the rotating portion 310 along the insertion direction of the hard disk 2000. The rotating portion 310 drives After the abutment portion 320 rotates into the installation cavity 200, the limiting member 300 is in a first state, and the abutment portion 320 is used to abut against the hard disk 2000 when the hard disk 2000 enters the installation cavity 200 and limit the hard disk 2000 to a predetermined position. After the rotating portion 310 drives the abutment portion 320 to rotate outside the installation cavity 200, the limiting member 300 is in a second state, so that the hard disk 2000 can continue to move into the installation cavity 200 and separate from the clamping member 210 before moving out of the installation cavity 200.

[0070] The connection point 130 on the side wall of the bracket body 100 is not a specific point on the side wall, but a structure on the side wall of the bracket body 100 that is rotatably connected to the limiting member 300. Figure 2As shown, a connection hole is provided at one end near the bottom on the side wall of the bracket body 100 for rotatably connecting with the rotating shaft on the limiting member 300, and this connection hole is the connection point 130. Of course, the connection point 130 can also be a connecting shaft provided on the side wall of the bracket body 100, and the rotating connection between the limiting member 300 and the side wall of the bracket body 100 is achieved by inserting this connecting shaft into the connection hole on the limiting member 300.

[0071] The rotating part 310 is a structure for the limiting member 300 to rotatably connect with the side wall of the bracket body 100. After the rotating part 310 is rotatably connected with the side wall of the bracket body 100, due to the fixed position of the connection point 130, no matter how the rotating part 310 rotates, the position where the rotating part 310 is connected to the connection point 130 will be fixed in one place. When the distance between the connection point 130 and the bottom of the installation cavity 200 is greater than the height of the hard disk 2000, no matter how the rotating part 310 rotates, at least part of the rotating part 310 will be located above the hard disk 2000, resulting in a relatively high height of the hard disk bracket 1000. Therefore, as Figure 6 shown, the distance between the connection point 130 and the bottom of the installation cavity 200 can be set to be less than the height of the hard disk 2000, so that when the rotating part 310 rotates to a certain state, it can be entirely located between the hard disk 2000 and the side wall of the bracket body 100. In addition to being set at a position near the bottom of the installation cavity 200 as Figure 2 shown, the connection point 130 can also be set at the middle position on the side wall of the bracket body 100, as long as it is ensured that after the hard disk 2000 enters the installation cavity 200, the connection point 130 is not above the hard disk 2000.

[0072] The abutting part 320 is a structure for the limiting member 300 to abut against the hard disk 2000 and limit the hard disk 2000 at a predetermined position. When the distance between the connection point 130 and the bottom of the installation cavity 200 is set to be less than the height of the hard disk 2000, no matter how the rotating part 310 rotates, at least part of the structure will be located between the hard disk 2000 and the side wall of the bracket body 100. At this time, if the dimension of the rotating part 310 along the insertion direction of the hard disk 2000 is greater than the dimension of the abutting part 320 along the insertion direction of the hard disk 2000, it will cause the hard disk 2000 to abut against the rotating part 310 first when the hard disk 2000 enters the installation cavity 200, and it cannot reach the predetermined position limited by the abutting part 320, making the hard disk 2000 unable to be engaged with the engaging member 210. Therefore, the dimension of the abutting part 320 along the insertion direction of the hard disk 2000 needs to be greater than the dimension of the rotating part 310 along the insertion direction of the hard disk 2000, that is, as Figure 5 shown, when the limiting member 300 has a stepped structure, the structure with a larger thickness on the limiting member 300 is the abutting part 320, and the structure with a smaller thickness is the rotating part 310. In addition, in addition to being as Figure 5In addition to the L shape shown, when there is a certain distance between the connection point 130 and the installation cavity 200, the rotating part 310 and the abutting part 320 can also be in a T shape. When the limiting part 300 is in the second state, the abutting part 320 can extend upward from the bottom of the installation cavity 200, so that the hard disk 2000 can abut against the abutting part 320 at various positions in the vertical direction and will not shift in the vertical direction when entering the installation cavity 200.

[0073] As Figure 3 shown, when the limiting part 300 is in the first state, the rotating part 310 drives the abutting part 320 to rotate into the installation cavity 200, that is, both the rotating part 310 and the abutting part 320 are located in the installation cavity 200. At this time, as Figure 4 shown, after the hard disk 2000 enters the installation cavity 200, it will abut against the abutting part 320, and the rotating part 310 will be located between the side wall of the bracket body 100 and the hard disk 2000. As Figure 5 shown, when the limiting part 300 is in the second state, the rotating part 310 drives the abutting part 320 to rotate out of the installation cavity 200, that is, the abutting part 320 is completely located outside the installation cavity 200. Only the rotating part 310 is between the side wall of the bracket body 100 and the hard disk 2000. Because the thickness of the rotating part 310 is less than the thickness of the abutting part 320, there will be a certain space between the rotating part 310 and the hard disk 2000. At this time, the hard disk 2000 can continue to move inward into the installation cavity 200 until as Figure 6 shown, it abuts against the rotating part 310, separating the hard disk 2000 from the clamping part 210.

[0074] In the above embodiments, on the one hand, the rotating part 310 is rotatably connected to the connection point 130, so that there is no need to provide other movable connection structures such as sliding rails on the side wall of the bracket body 100. On the other hand, the distance between the connection point 130 and the bottom of the installation cavity 200 is set to be less than the height of the hard disk 2000, and the dimension of the abutting part 320 along the insertion direction of the hard disk 2000 is set to be greater than the dimension of the rotating part 310 along the insertion direction of the hard disk 2000. When the limiting part 300 is in the first state, the whole structure can be rotated into the installation cavity 200, and only by driving the abutting part 320 to rotate through the rotating part 310, the abutting part 320 can be driven out of the installation cavity 200, so that the limiting part 300 is in the second state, without setting the height of the hard disk bracket 1000 to be higher than the height of the hard disk 2000 to connect the abutting part 320 located outside the installation cavity 200, effectively reducing the height of the hard disk bracket 1000 and the space occupied by the hard disk bracket 1000 in the electronic device.

[0075] If there is no structure at the bottom of the installation cavity to limit the position of the hard disk, it will be difficult to align the fixing holes on the hard disk with the engaging parts when installing the hard disk, and thus the hard disk cannot be engaged with the engaging parts even when it is inserted into the predetermined position. Therefore, in order to ensure that the fixing holes of the hard disk can be aligned with the engaging parts, in some embodiments of the present application, such as Figure 2 and Figure 9 shown, Figure 9 shows a schematic structural view of the second state of the limiting member provided by the embodiment of the present invention from another angle. The bracket body 100 includes a bottom plate 140, and the bottom plate 140 is located at the bottom of the installation cavity 200 and is used to carry the hard disk 2000. When the limiting member 300 is in the second state, the distance between the bottom end of the abutting portion 320 and the bottom plate 140 is greater than the height of the hard disk 2000.

[0076] The side wall of the bracket body 100 can limit the horizontal movement of the hard disk 2000, so that the hard disk 2000 can enter the installation cavity 200 normally, and the bottom plate 140 at the bottom of the installation cavity 200 can limit the vertical movement of the hard disk 2000. When setting the engaging part 210, as long as the distance between the engaging part 210 and the bottom plate 140 is adapted to the distance between the fixing hole 2100 on the hard disk 2000 and the bottom of the hard disk 2000, when the hard disk 2000 enters the installation cavity 200, as Figure 9 shown, the engaging part 210 will be aligned with the fixing hole 2100. After the hard disk 2000 is inserted into the predetermined position, when the engaging part 210 is reset, it can be directly inserted into the fixing hole 2100, thereby realizing the engagement between the engaging part 210 and the hard disk 2000.

[0077] Since the bottom plate 140 is located at the bottom of the installation cavity 200, the hard disk 2000 can only be removed from the top of the installation cavity 200. However, as Figure 9 shown, when the hard disk 2000 abuts against the rotating part 310, the place where the abutting part 320 is connected to the rotating part 310 will extend towards the hard disk 2000 to form a limiting wall, restricting the upward movement of the hard disk 2000 towards the installation cavity 200. At this time, if the distance between the bottom end of the abutting part 320 and the bottom plate 140 is the same as the height of the hard disk 2000, the hard disk 2000 will be stuck and fixed between the abutting part 320 and the bottom plate 140. Therefore, the distance between the bottom end of the abutting part 320 and the bottom plate 140 needs to be greater than the height of the hard disk 2000, so that there is a height difference D1 between the abutting part 320 and the hard disk 2000. In this way, as Figure 8 shown, the end of the hard disk 2000 far from the limiting member 300 can be moved upward by a certain distance, and the hard disk 2000 can be removed from the installation cavity 200 in an inclined state from above the installation cavity 200.

[0078] In the above embodiment, by providing the bottom plate 140 and the bottom plate 140 being located at the bottom of the installation cavity 200, the movement of the hard disk 2000 in the vertical direction is restricted, and the fixing hole 2100 on the hard disk 2000 is ensured to be aligned with the clamping member 210 when the hard disk 2000 enters the installation cavity 200, thereby ensuring that when the hard disk 2000 is inserted into the predetermined position, the clamping member 210 can be reset and inserted into the fixing hole 2100 to be clamped with the hard disk 2000. In addition, when the limiting member 300 is in the second state, the distance between the bottom end of the abutting portion 320 and the bottom plate 140 is greater than the height of the hard disk 2000, so that the hard disk 2000 can be normally moved out from the top of the installation cavity 200.

[0079] When the limiting member is in the first state, the entire limiting member will be located in the installation cavity and between the side wall of the bracket body and the hard disk. Therefore, in order to more conveniently rotate the limiting member from the first state to the second state, in some embodiments of the present application, such as Figure 3 and Figure 5 As shown, one end of the abutting portion 320 away from the rotating portion 310 extends outward to form a handle 330. The handle 330 and the rotating portion 310 are respectively located on both sides of the abutting portion 320. When the limiting member 300 is in the second state, the rotating portion 310 is located below the abutting portion 320, and the handle 330 is located above the abutting portion 320. When the limiting member 300 is rotated to the first state, the limiting member 300 can be rotated by conveniently grasping the handle 330.

[0080] like Figure 3 As shown, when the connection point between the rotating part 310 and the side wall of the bracket body 100 is located at the bottom of the side wall, the handle 330 and the rotating part 310 can be located at both ends of the abutting part 320 respectively, and when the limiting member 300 is in the first state, the rotating part 310 is located at one end of the abutting part 320 facing the bottom of the installation cavity 200, and the handle 330 is located at one end of the abutting part 320 facing the top of the installation cavity 200. Of course, when the connection point between the rotating part 310 and the side wall of the bracket body 100 is located at the top of the side wall, the handle 330 and the rotating part 310 can be located on both sides of the same end of the abutting part 320, so that when the limiting member 300 is in the first state, the handle 330 and the rotating part 310 can be located together at one end of the abutting part 320 facing the top of the installation cavity 200. By arranging the handle 330 in this way, when the limiting member 300 is in the first state, the handle 330 can be grasped more conveniently to rotate the limiting member 300 to the second state.

[0081] In order to make the rotation of the limiting member more labor-saving, the rotational frictional force between the rotating portion and the bracket body is usually set to be relatively small, which results in the limiting member being prone to rotate under the action of gravity, and further makes it difficult for the limiting member to be restricted to the first state or the second state. Therefore, in some embodiments of the present application, in order to limit the limiting member to the first state or the second state, such as Figure 2 , Figure 10 and Figure 11 shown, Figure 10 shows Figure 2 an enlarged schematic view of part A in Figure 11 is Figure 8 a sectional structure schematic view along the A-A direction in . A rotating shaft 340 is provided on the rotating portion 310. The connection point 130 is a connection hole 131. The rotating shaft 340 is rotatably connected to the connection hole 131. A first limiting wall 132 and a second limiting wall 133 are provided in the connection hole 131. Both the first limiting wall 132 and the second limiting wall 133 are parallel to the axis of the connection hole 131. A clamping protrusion 341 is provided on the outer side wall of the rotating shaft 340. The two circumferentially opposite sides of the clamping protrusion 341 are respectively used to abut against the first limiting wall 132 or the second limiting wall 133 when the rotating shaft 340 rotates, so as to limit the limiting member 300 to the first state or the second state.

[0082] The rotating shaft 340 is provided on the side of the rotating portion 310 away from the opening 110. The rotating shaft 340 is inserted into the connection hole 131 along the insertion direction of the hard disk 2000. As Figure 11 shown, a clamping protrusion 341 is provided on the outer side wall of the rotating shaft 340. Part of the inner side wall of the connection hole 131 extends inward to form a first limiting wall 132 and a second limiting wall 133. As Figure 11 shown in , the limiting member 300 is in the second state, and the lower side of the clamping protrusion 341 abuts against the second limiting wall 133. At this time, the rotating shaft 340 is restricted by the second limiting wall 133 and can only rotate in the direction shown by arrow C and cannot continue to rotate in the direction shown by arrow B, so that the limiting member 300 is restricted to the second state. As Figure 12 shown, Figure 12 is Figure 11 a sectional structure schematic view of the limiting member after rotating in the direction shown by arrow C on the basis of . The limiting member 300 is in the first state, and the right side of the clamping protrusion 341 abuts against the first limiting wall 132. At this time, the rotating shaft 340 is restricted by the second limiting wall 133 and can only rotate in the direction shown by arrow B and cannot continue to rotate in the direction shown by arrow C, so that the limiting member 300 is restricted to the first state.

[0083] In addition to the first limiting wall 132 and the second limiting wall 133 as Figure 11 and Figure 12In addition to the two outer sides of the large protrusion extending inward from the inner side wall of the connection hole 131, it can also be the side walls of the two small protrusions formed by the inner side wall of the connection hole 131 extending into the connection hole 131. In addition to the large protrusion as shown in Figure 11 and Figure 12 , the positioning protrusion 341 can also be two small protrusions arranged at intervals. The distance between the first limiting wall 132 and the second limiting wall 133 is related to the size of the positioning protrusion 341. The larger the space that the positioning protrusion 341 can pass through between the first limiting wall 132 and the second limiting wall 133, the longer the arc length of the positioning protrusion 341 (when the positioning protrusion 341 is two small protrusions, this arc length is the arc length around the inner wall of the connection hole 131 between the sides of the two small protrusions respectively abutted against the first limiting wall 132 and the second limiting wall 133). The smaller the space that the positioning protrusion 341 can pass through between the first limiting wall 132 and the second limiting wall 133, the shorter the arc length of the positioning protrusion 341.

[0084] In addition, the angle difference between the central angle corresponding to the space that the positioning protrusion 341 can pass through between the first limiting wall 132 and the second limiting wall 133 and the central angle corresponding to the arc length of the positioning protrusion 341 is the angle by which the limiting member 300 can rotate relative to the bracket body 100. As an example, as shown in Figure 11 and Figure 12 , the central angle corresponding to the space that the positioning protrusion 341 can pass through between the first limiting wall 132 and the second limiting wall 133 is 270 degrees, and the central angle corresponding to the arc length of the positioning protrusion 341 is 180 degrees. The angle difference between the two is 90 degrees. Therefore, when the limiting member 300 is switched between the first state and the second state, it needs to rotate 90 degrees relative to the bracket body 100.

[0085] Therefore, in practical applications, the positioning protrusion 341 of different sizes and the positional relationship between the first limiting wall 132 and the second limiting wall 133 can be set as needed, as long as it is ensured that the limiting member 300 is restricted to the first state when the positioning protrusion 341 abuts against the first limiting wall 132, and the limiting member 300 is restricted to the second state when the positioning protrusion 341 abuts against the second limiting wall 133.

[0086] In the above embodiments, by providing the first limiting wall 132 and the second limiting wall 133 in the connection hole 131, and providing the positioning protrusion 341 on the rotating shaft 340, the angle of rotation of the limiting member 300 relative to the bracket body 100 is restricted, so that the limiting member 300 can be restricted to the first state or the second state without deviation, thereby making the disassembly and assembly of the hard disk 2000 more convenient.

[0087] In order to prevent the limiting member from separating from the bracket body, in some embodiments of the present application, as shown in Figure 10 and Figure 13a andFigure 13b As shown Figure 13a Fig. shows a perspective view of another angle of the hard disk bracket provided by the embodiment of the present invention Figure 13b is Figure 13a a schematic cross-sectional structure diagram along the B-B direction in. A limiting protrusion 342 is provided at one end of the rotating shaft 340 away from the rotating part 310. The limiting protrusion 342 passes through the connecting hole 131 and is clamped with the orifice surface on the side of the connecting hole 131 away from the installation cavity 200. The limiting protrusion 342 can be as Figure 10 shown, a large protrusion formed by extending outward from the outer side wall of the rotating shaft 340, or can be composed of a plurality of small protrusions formed by extending outward from the outer side wall of the rotating shaft 340.

[0088] As Figure 13b shown, a receiving groove 134 communicating with the connecting hole 131 can be opened on the side wall where the connecting hole 131 is located to receive the limiting protrusion 342. The orifice of the receiving groove 134 is larger than the orifice of the connecting hole 131, so that a limiting structure is formed at the connection between the receiving groove 134 and the connecting hole 131 to be clamped with the limiting protrusion 342. When the side wall where the connecting hole 131 is located is relatively thin, the connecting hole 131 can penetrate through the side wall, so that the limiting protrusion 342 is clamped with the surface of the side wall away from the installation cavity 200 to prevent the limiting member 300 from separating from the bracket body 100 during rotation.

[0089] In the above embodiment, the limiting protrusion 342 is provided on the rotating shaft 340 to be clamped with the orifice surface on the side of the connecting hole 131 away from the installation cavity 200, so as to limit the moving distance of the limiting member 300 along the axis of the connecting hole 131, effectively avoiding the problem that the limiting member 300 separates from the bracket body 100 during rotation.

[0090] When assembling the hard disk bracket, in order to more conveniently connect the limiting member and the bracket body, in some embodiments of the present application, as Figure 11 and Figure 13b shown, one end of the rotating shaft 340 away from the rotating part 310 is decomposed into a plurality of parts 343. There is a gap between the plurality of parts 343. The limiting protrusion 342 has a second inclined surface 344. The second inclined surface 344 is used to abut against the inner wall of the connecting hole 131 when the rotating shaft 340 passes through the connecting hole 131 along the direction away from the installation cavity 200, so that the plurality of parts 343 approach each other, and then one end of the rotating shaft 340 away from the rotating part 310 passes through the connecting hole 131.

[0091] As Figure 11 and Figure 13b shown, the rotating shaft 340 is decomposed into two parts 343 along its axial direction, and there is a gap between the two parts 343. As Figure 2As shown, when the limiting member 300 is moved to the left to insert the rotating shaft 340 into the connection hole 131, the second inclined surface 344 will abut against the inner wall of the connection hole 131, causing the two split parts 343 to approach each other. As a result, the limiting protrusion 342 can pass through the connection hole 131 and engage with the surface of the orifice on the side of the connection hole 131 away from the installation cavity 200. Of course, in addition to being decomposed into two split parts 343 as shown in Figure 11 and Figure 13b , the rotating shaft 340 can also be decomposed into three split parts 343, four split parts 343, etc. As long as there are gaps between the split parts 343 and they approach each other when the second inclined surface 344 abuts against the orifice of the connection hole 131, the limiting protrusion 342 can pass through the connection hole 131.

[0092] In the above embodiment, by decomposing the rotating shaft 340 into multiple split parts 343 and providing the second inclined surface 344 on the limiting protrusion 342, when assembling the limiting member 300 and the bracket body 100, the second inclined surface 344 will abut against the inner wall of the connection hole 131, causing the multiple split parts 343 to approach each other. As a result, the limiting protrusion 342 can pass through the connection hole 131 and engage with the surface of the orifice on the side of the connection hole 131 away from the installation cavity 200.

[0093] In some examples of the present application, as shown in Figure 7 , the clamping member 210 includes an elastic member 211 and a clamping portion 212. One end of the elastic member 211 is connected to the side wall of the bracket body 100, and the other end is connected to the clamping portion 212. The first inclined surface 220 is provided on the clamping portion 212. The elastic member 211 is used to deform when the clamping portion 212 moves away from the hard disk 2000 and provide a restoring elastic force to the clamping portion 212, so that the clamping portion 212 can be reset and fix the hard disk 2000 at a predetermined position when the hard disk 2000 is inserted to the predetermined position.

[0094] The elastic member 211 can be a spring, a spring sheet, etc. When the hard disk 2000 enters the installation cavity 200, the first inclined surface 220 on the clamping portion 212 will abut against the hard disk 2000, causing the clamping portion 212 to move towards the side wall of the bracket body 100. As a result, the elastic member 211 is compressed and provides an elastic force towards the installation cavity 200 to the clamping portion 212, so that the clamping portion 212 can move towards the installation cavity 200 and engage with the hard disk 2000 when the hard disk 2000 is inserted to the predetermined position. The elastic member 211 can also be a rubber member, a silica gel member, etc., which can be compressed to undergo elastic deformation.

[0095] Of course, in addition to being as shown in Figure 7As shown, they are all arranged inside the installation cavity 200. A groove can also be opened on the side wall of the bracket body 100. One end of the elastic member 211 is connected to the bottom of the groove, and the other end is connected to the clamping portion 212, so that when the first inclined surface 220 abuts against the hard disk 2000, the clamping portion 212 can be retracted into the groove, effectively reducing the space of the installation cavity 200 occupied by the elastic member 211. In addition, a through hole can be opened on the side wall of the bracket body 100, and one end of the clamping portion 212 passes through the through hole and extends to the outside of the side wall of the bracket body 100. At this time, the elastic member 211 can not only be set in the installation cavity 200 so as to be compressed and provide elastic force to the clamping portion 212 when the hard disk 2000 enters the installation cavity 200, but also can be set outside the installation cavity 200. For example, one end of the elastic member 211 is connected to the side of the side wall of the bracket body 100 away from the installation cavity 200, and the other end is connected to the end of the clamping portion 212 away from the installation cavity 200. When the first inclined surface 220 abuts against the hard disk 2000, the clamping portion 212 moves to the outside of the installation cavity 200 and stretches the elastic member 211, so that the elastic member 211 generates an elastic force. At this time, the elastic member 211 can not only be a spring, but also can be a component such as an elastic rope that can generate elastic force when stretched.

[0096] In the above embodiment, when the hard disk 2000 enters the installation cavity 200, the elastic member 211 provides elastic force to the clamping portion 212, so that the clamping portion 212 can fix the hard disk 2000 at a predetermined position when the hard disk 2000 is inserted into the predetermined position, thereby making the structure of the hard disk bracket 1000 more concise.

[0097] In order to further reduce the size of the hard disk bracket, in some embodiments of the present application, such as Figure 2 As shown, a avoidance hole 150 is opened on the side wall of the bracket body 100 adjacent to the opening 110, and the elastic member is a spring sheet 213 extending from the edge of the avoidance hole 150 to the inside of the avoidance hole 150, and the clamping portion 212 is arranged on the side of the spring sheet 213 facing the installation cavity 200, and the spring sheet 213 is used to deform as the clamping portion 212 moves in a direction away from the hard disk 2000, so as to provide a reset elastic force to the clamping portion 212.

[0098] The hard disk bracket 1000 is usually made of materials such as metal alloys (e.g., aluminum alloy, stainless steel, cold-rolled steel plate, etc.) and engineering plastics [polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), PC+ABS alloy, etc.]. These materials usually have a certain strength and elasticity, that is, these materials allow elastic deformation within a certain range. Therefore, an avoidance hole 150 can be formed on the side wall of the bracket body 100. A spring piece 213 (i.e., the elastic member included in the clamping member 210) extends from the edge of the avoidance hole 150 into the interior of the avoidance hole 150, and the clamping portion 212 is provided at one end of the spring piece 213 facing away from the edge of the avoidance hole 150. When the hard disk 2000 enters the installation cavity 200, the hard disk 2000 abuts against the first inclined surface 220, causing the clamping portion 212 to move outward from the installation cavity 200, causing the end of the spring piece 213 where the clamping portion 212 is located to bend outward and generate an elastic force. When the hard disk 2000 is inserted to a predetermined position, the spring piece 213 returns to its original state, so that the clamping portion 212 is reset and clamped with the hard disk 2000. The avoidance hole 150 can be a long hole, and the spring piece 213 extends from the edge of the avoidance hole 150 along the length direction of the avoidance hole 150 into the interior of the avoidance hole 150, so that the length of the spring piece 213 is greater, and thus it can undergo a greater elastic deformation.

[0099] In the above embodiment, by forming the avoidance hole 150 on the side wall of the bracket body 100 and extending the spring piece 213 from the edge of the avoidance hole 150 into the interior of the avoidance hole 150 as the elastic member included in the clamping member 210, it is used to provide a reset elastic force to the clamping portion 212 when the first inclined surface 220 abuts against the hard disk 2000. Such a structure, on the one hand, enables the clamping member 210 and the bracket body 100 to be formed by integral injection molding, making the production process simpler and more convenient, and can reduce the number of independent parts, avoiding part loss; on the other hand, there is no need to reserve space between the side wall of the hard disk 2000 and the bracket body 100 to accommodate the clamping member 210, which can not only reduce the volume of the hard disk bracket 1000, but also the side wall of the bracket body 100 can abut against the hard disk 2000 and provide a certain frictional force to the hard disk 2000, which can increase the stability of the hard disk 2000.

[0100] According to another aspect of the embodiments of the present application, an electronic device is provided, and the electronic device includes the hard disk bracket described in any of the above embodiments.
