[0002] The computer hard disk is the most important storage device of computer, and currently the hard disk has problems such as low heat dissipation efficiency, poor installation stability and large power consumption, which seriously affects the actual use experience of users.

In order to meet the use requirements of more scenes, multiple solid state disks with M.2 as the interface form are usually configured in the server as storage media.

[0067] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0068] According to one specific embodiment of the present application, asFigures 1 to 9 As shown in the figure, a fixing member for a solid state hard disk is used to install the solid state hard disk 1 loaded with the heat sink 5 on the PCB board 6. The fixing member includes a sheet metal bracket 2, a buckle 3 and a latch 4. The sheet metal bracket 2 is arranged on the PCB board 6 to install the solid state hard disk 1 and the heat sink 5. The gold finger at one end of the solid state hard disk 1 is inserted into the hard disk slot 61 of the PCB board 6, and the other end of the solid state hard disk 1 is provided with a first arc groove 11. The sheet metal bracket 2 is provided with a second arc groove 21 corresponding to the position of the first arc groove 11, and the PCB board 6 is provided with a jack 62 corresponding to the position of the first arc groove 11. The buckle 3 includes an elastic clamping part 31, a bracket fixing part 32 and a hard disk limiting part 33. The elastic clamping part 31 is clamped in the jack 62, so that the hard disk limiting part 33 and the first arc groove 11 are limited to cooperate to form a clamping of the solid state hard disk 1, and the bracket fixing part 32 and the second arc groove 21 are limited to cooperate to form a clamping of the sheet metal bracket 2. The hard disk limiting part 33 is provided with a pin hole 332, and the latch 4 is inserted into the pin hole 332 to lock the solid state hard disk 1, the sheet metal bracket 2 and the PCB board 6 together.

[0069] In this embodiment, the solid state hard disk 1, the sheet metal bracket 2 and the PCB board 6 are locked together by the cooperation of the buckle 3 and the latch 4. Compared with the traditional copper column fixing method, the structural strength of the tail of the solid state hard disk 1 can be greatly strengthened, so that the deformation amount of the tail of the solid state hard disk 1 under external force can be effectively reduced, and the dislocation between the heat sink 5 and the solid state hard disk 1 due to external force impact can be fundamentally eliminated, and the risk of damage to the components on the PCB board 6 can be reduced.

[0070] In this embodiment, referring to Figure 1 and Figure 2PCB board 6 is provided with a hard disk slot 61 and other components with different functions, and the hard disk slot 61 and other components are used as a carrier for data signal transmission through the printed circuit. The hard disk slot 61 is preferably installed on one side of the PCB board 6, and the other side of the PCB board 6 is provided with a jack 62. The gold finger at one end of the solid state disk 1 is inserted into the hard disk slot 61, and the contacts of the gold finger are electrically connected to the contacts in the hard disk slot 61 one by one to realize data transmission and conversion. The first arc groove 11 is provided on the end of the PCB board 6 away from the gold finger, and when the gold finger is inserted into the hard disk slot 61, the first arc groove 11 is arranged opposite to the jack 62. Thus, when the elastic clamping part 31 of the buckle member 3 is clamped in the jack 62, the hard disk limiting part 33 of the buckle member 3 is limited and matched with the first arc groove 11 to fix the solid state disk 1 on the PCB board 6. That is to say, only the distance between the hard disk slot 61 and the jack 62 on the PCB board 6 is equal to the length of the solid state disk 1 to form the installation and fixation of the solid state disk 1, and the specific positions of the hard disk slot 61 and the jack 62 on the PCB board 6 can be flexibly set according to actual use requirements, which are not limited here and any position is within the protection scope of the patent.

[0071] Further, in the embodiment, referring to Figure 1 , Figure 2 , Figure 6 and Figure 7 , the sheet metal support 2 is arranged on the PCB board 6 to fix the solid state disk 1 and the heat sink 5. As a preferred scheme of the embodiment, the sheet metal support 2 specifically can include a sheet metal main plate 22 and two sheet metal side plates 23 arranged on opposite sides of the sheet metal main plate 22, and the two sheet metal side plates 23 and the sheet metal main plate 22 are arranged vertically.

[0072] Preferably, the sheet metal main plate 22 can be in a strip-shaped structure, and the length of the sheet metal main plate 22 is less than the length of the solid state disk 1. The sheet metal main plate 22 is installed on the PCB board 6 and located between the hard disk slot 61 and the jack 62. The second arc groove 21 can be arranged at the end of the sheet metal main plate 22 corresponding to the position of the jack 62 and the first arc groove 11 to abut the support fixing part 32 of the buckle member 3. When the elastic clamping part 31 is clamped in the jack 62, the hard disk limiting part 33 is limited and matched with the first arc groove 11 to form the clamping of the solid state disk 1, and the support fixing part 32 is limited and matched with the second arc groove 21 to form the clamping of the sheet metal support 2.

[0073] Further, referring to Figure 1 and Figure 2, the solid state disk 1 is loaded on the sheet metal main plate 22, and the gold fingers at one end of the solid state disk 1 extend to the outside of the sheet metal main plate 22, used to dock the hard disk slot 61, and the first arc groove 11 at the other end of the solid state disk 1 and the second arc groove 21 of the sheet metal main plate 22 are arranged in correspondence. As a preferred embodiment of the present embodiment, the sheet metal main plate 22 can be fixed on the PCB 6 by means of welding, buckling or screw locking, which can greatly improve the stability of the fin 5 and the solid state disk 1 during external force impact. Of course, since the opposite ends of the solid state disk 1 are fixed by the hard disk slot 61 and the hard disk limiting part 33 respectively, the two sheet metal side plates 23 form clamping to the opposite two side edges of the solid state disk 1, so that the sheet metal main plate 22 is directly fixed on the PCB 6 by the limiting force of the two ends of the solid state disk 1, without external auxiliary fixing parts, which is also within the protection scope of the present patent.

[0074] Further, referring to Figure 2 and Figure 7 , the opposite two side edges of the fin 5 are respectively provided with a plurality of buckling positions 51, and the two sheet metal side plates 23 are respectively provided with a plurality of buckling grooves 231 corresponding to the buckling positions 51, and the plurality of buckling positions 51 and the plurality of buckling grooves 231 are one-to-one clamped and embedded to load the fin 5 on the sheet metal support 2. Among them, the plurality of buckling grooves 231 can be preferably arranged on the side of the sheet metal side plate 23 away from the sheet metal main plate 22, so that a gap is formed between the fin 5 and the solid state disk 1. The present embodiment loads the solid state disk 1 by adding the sheet metal support 2, and separately fixes the fin 5 on the two sheet metal side plates 23 of the sheet metal support 2, so that the fin 5 and the solid state disk 1 are arranged in direct correspondence and do not contact. Compared with the conventional way of limiting fixation between the solid state disk 1 and the fin 5 through the heat-conducting silica gel sheet 7, the present embodiment can fundamentally solve the risk of misalignment of the solid state disk 1 and the fin 5 due to external force.

[0075] Preferably, the sheet metal main plate 22 and the two sheet metal side plates 23 can be integrally stamped from a sheet metal piece, which can greatly improve the structural strength of the sheet metal support 2 acting on the solid state disk 1 and the fin 5. More preferably, the sheet metal support 2 can be made of aluminum alloy or copper material with good heat dissipation performance, which can assist the solid state disk 1 in heat dissipation, thereby providing better user experience.

[0076] It is worth mentioning that, in the present embodiment, in order to further improve the heat dissipation effect of the solid state disk 1, referring to Figure 2 and Figure 7, the heat-conducting silica gel sheet 7 is arranged between the solid state hard disk 1 and the metal support 2. Specifically, the two metal side plates 23 of the metal support 2 are respectively provided with a plurality of abutting protrusions 232 adjacent to the metal main plate 22, and the distance between the abutting protrusions 232 and the metal main plate 22 is equal to the thickness of the heat-conducting silica gel sheet 7. Thus, when the solid state hard disk 1 abuts against the abutting protrusions 232 of the two metal side plates 23, the upper and lower end faces of the heat-conducting silica gel sheet 7 abut against the solid state hard disk 1 and the metal main plate 22 respectively, so as to transfer the heat on the solid state hard disk 1 to the metal support 2.

[0077] Further, referring to Figure 2 and Figure 3 , the heat-conducting silica gel sheet 7 is also arranged between the heat dissipation fin 5 and the solid state hard disk 1. Preferably, the heat-conducting silica gel sheet 7 is attached to the side of the heat dissipation fin 5 facing the solid state hard disk 1. Thus, the heat emitted by the solid state hard disk 1 is transferred upward to the heat dissipation fin 5 through the heat-conducting silica gel sheet 7 to assist the heat dissipation of the solid state hard disk 1. The heat emitted by the solid state hard disk 1 is also transferred downward to the metal support 2 through the heat-conducting silica gel sheet 7 to assist the heat dissipation. The double heat dissipation structure can greatly improve the heat dissipation effect of the solid state hard disk 1.

[0078] It is worth mentioning that the heat dissipation fin 5 can be made of aluminum alloy or copper material with good heat dissipation performance, so as to assist the heat dissipation of the solid state hard disk 1 and provide better user experience.

[0079] Further, it is worth mentioning that the materials and structures of the heat-conducting silica gel sheet 7 between the metal support 2 and the PCB 6, the heat-conducting silica gel sheet 7 between the solid state hard disk 1 and the metal support 2, and the heat-conducting silica gel sheet 7 between the heat dissipation fin 5 and the solid state hard disk 1 can be inconsistent. Any material and structure that can achieve heat conduction effect is within the protection scope of the present patent, and will not be described in detail here.

[0080] In the embodiment, referring to Figure 4 and Figure 5 , the elastic clamping portion 31, the support fixing portion 32 and the hard disk limiting portion 33 of the buckle member 3 can be preferably designed in an integrated manner. Thus, the structural strength of the buckle member 3 during use can be greatly improved, and the locking effect on the solid state hard disk 1, the metal support 2 and the PCB 6 can be improved. Compared with the traditional copper column fixing method, the structure strength of the tail portion of the solid state hard disk 1 can be greatly strengthened by the cooperation of the buckle member 3 and the latch member 4, so as to effectively reduce the deformation amount of the tail portion of the solid state hard disk 1 when subjected to external force and improve the stability.

[0081] As a preferred scheme of the embodiment, referring to Figure 4 and Figure 8The bracket fixing portion 32 comprises a fixing portion main body 321 and a locking portion arranged at the edge of the fixing portion main body 321. The fixing portion main body 321 can preferably be a cylindrical structure matching the profile of the second arc-shaped groove 21, and the metal bracket 2 is provided with a matching portion adjacent to the second arc-shaped groove 21. When the fixing portion main body 321 is clamped in the second arc-shaped groove 21, the locking portion and the matching portion are locked and matched to fix the metal bracket 2 on the buckle 3.

[0082] Specifically, the locking portion can preferably comprise two angularly arranged extension arms 322, which can be preferably arranged at the side edges of the upper end surface of the fixing portion main body 321. Each extension arm 322 extends downward from one end away from the fixing portion main body 321 to form a protrusion 323. The matching portion comprises two recesses 24 arranged adjacent to the second arc-shaped groove 21. When the fixing portion main body 321 is clamped in the second arc-shaped groove 21, the two protrusions 323 are respectively clamped and matched with the two recesses 24 arranged on the upper end surface of the metal main plate 22 to lock the metal bracket 2 on the PCB 6. In this embodiment, the clamping and matching of the two protrusions 323 and the two recesses 24 can ensure that the metal bracket 2 does not drive the solid state drive 1 and the heat sink 5 to move transversely along the PCB 6, and ensure that the metal bracket 2 and the PCB 6 have a unique assembly posture.

[0083] It is worth mentioning that in this embodiment, the locking portion is not limited to the structure of the two extension arms 322, and the matching portion is not limited to the structure of the two recesses 24, as long as the locking portion and the matching portion are locked and matched to fix the metal bracket 2 on the buckle 3, and any structure change is within the protection scope of this patent. It is also worth mentioning that in this embodiment, the protrusion 323 can be a cylindrical structure, which can also be a square column or other regular or irregular structure, which is not limited here. As long as the recess 24 and the protrusion 323 are matched in profile to form a limiting clamping, it is acceptable. Of course, the recess 24 can also penetrate the wall thickness of the metal main plate 22, which is within the protection scope of this patent. It is also worth mentioning that in this embodiment, the fixing portion main body 321, the extension arm 322 and the protrusion 323 can be designed in one piece, which can greatly improve the structural strength of the bracket fixing portion 32, and further improve the locking effect of the metal bracket 2.

[0084] Further, in this embodiment, referring to Figure 4 and Figure 9The hard disk limiting portion 33 is located on the upper end surface of the fixing portion main body 321, and is preferably coaxially arranged with the fixing portion main body 321. The hard disk limiting portion 33 is provided with a limiting convex platform 331 on one side for clamping and fitting with the first arc slot 11, and the profile of the limiting convex platform 331 is matched with the first arc slot 11. It is worth mentioning that in the embodiment, the limiting convex platform 331 can make the hard disk limiting portion 33 form two symmetrical abutting end surfaces 333. When the limiting convex platform 331 extends and is embedded in the first arc slot 11, the two abutting end surfaces 333 abut on the end of the solid state disk 1 away from the gold finger, and correspond to the opposite sides of the first arc slot 11, so as to clamp the end of the solid state disk 1, and the bottom surface of the solid state disk 1 abuts on the upper end surface of the fixing portion main body 321, thereby limiting the solid state disk 1 from moving along the length direction and the longitudinal direction, and improving the stability of the solid state disk 1 during use, and ensuring that the solid state disk 1 can always remain stable even if it is subjected to external force.

[0085] Further, in the embodiment, referring to Figure 4 and Figure 5 The elastic clamping portion 31 is located on the lower end surface of the fixing portion main body 321, and is coaxially arranged with the fixing portion main body 321, for clamping and fitting with the jack 62 on the PCB 6, so that the hard disk limiting portion 33 and the first arc slot 11 are limited and fitted, to form clamping of the solid state disk 1, and the bracket fixing portion 32 and the second arc slot 21 are limited and fitted, to form clamping of the metal bracket 2.

[0086] As a preferred scheme of the embodiment, the elastic clamping portion 31 can include a plurality of elastic arms 311 and a plurality of clamping pieces 312. The plurality of elastic arms 311 are arranged around the edge of the lower end surface of the fixing portion main body 321, and are arranged in sequence. In the embodiment, the number of elastic arms 311 is at least two, and the profiles formed by the at least two elastic arms 311 are matched with the jack 62. A gap is formed between the at least two elastic arms 311, which is configured to allow the elastic arms 311 to approach each other when they are subjected to external pressure, and to return to the initial state when the external force is removed. Specifically, referring to Figure 4 and Figure 5, a first abutting step 313 is formed between the elastic supporting arms 311 and the fixing part body 321, and a clamping piece 312 is arranged at one end of each elastic supporting arm 311 away from the fixing part body 321, and a second abutting step 314 is formed between the clamping piece 312 and the elastic supporting arm 311. During the process of penetrating the insertion hole 62, the clamping pieces 312 are pressed by the hole wall of the insertion hole 62 and are brought close to each other, and simultaneously drive the elastic supporting arms 311 to be close to each other, so as to ensure that the clamping pieces 312 can penetrate the insertion hole 62. After the clamping pieces 312 penetrate the insertion hole 62, the elastic supporting arms 311 are located inside the insertion hole 62, and the elastic supporting arms 311 start to rebound after the clamping pieces 312 are released from the limiting, so that the first abutting step 313 and the second abutting step 314 abut the upper and lower end faces of the PCB 6 respectively, and finally realize the clamping and embedding cooperation between the elastic clamping part 31 and the insertion hole 62 of the PCB 6.

[0087] It is worth mentioning that the number of the elastic supporting arms 311 and the specific structure of the clamping piece 312 can not be limited in the embodiment, and any technical solution capable of realizing the clamping and embedding cooperation between the elastic clamping part 31 and the insertion hole 62 is within the protection scope of the patent, and will not be specifically expanded here.

[0088] Further, in the embodiment, referring to Figure 4 and Figure 5 , the pin hole 332 can penetrate from the upper end of the hard disk limiting part 33 to the lower end of the elastic clamping part 31, that is, the pin hole 332 can preferably penetrate the upper and lower ends of the buckling piece 3, so that after the insertion piece 4 is completely inserted into the pin hole 332, the buckling piece 3 can be ensured to be affected by the force of the insertion piece 4 at any position along the axial direction of the buckling piece 3, thereby the locking effect on the solid state disk 1, the metal support 2 and the PCB 6 can be greatly improved.

[0089] As a preferred scheme of the embodiment, referring to Figure 4 and Figure 5, the latch 4 can include a limiting seat 41 and a limiting pin 42 installed on the limiting seat 41. When the latch 4 and the buckle 3 are relatively connected and matched, the limiting pin 42 is inserted into the pin hole 332, the limiting seat 41 abuts against the upper end surface of the hard disk limiting portion 33 of the solid state disk 1, so as to realize the locking of the solid state disk 1, the metal support 2 and the PCB 6. In the embodiment, the length of the limiting pin 42 is greater than or equal to the hole depth of the pin hole 332, and the limiting pin 42 and the pin hole 332 are in interference fit, so that the user needs to exert a large external force to pull out the limiting pin 42 from the pin hole 332, which can greatly improve the fixing strength of the solid state disk 1. Of course, the buckle and the buckle groove 231 can be arranged on the limiting pin 42, and the buckle and the buckle groove 231 can be arranged on the hole wall of the pin hole 332, and the limiting effect of the limiting pin 42 and the pin hole 332 can also be achieved through the limiting fit of the buckle and the buckle groove 231.

[0090] Further, in the embodiment, the limiting seat 41 and the support fixing portion 32 are connected through the flexible connecting piece 8, so that the loss of the buckle 3 and / or the latch 4 can be effectively avoided, and the user can quickly disassemble and assemble the solid state disk 1. It is worth mentioning that the arc-shaped concave portion 81 can be arranged on the inner side of the bending of the flexible connecting piece 8, which can effectively avoid the generation of a large stress in the bending process of the flexible connecting piece 8, so as to effectively avoid that the stress causes the movement of the limiting pin 42 relative to the pin hole 332 or even the disengagement of the limiting pin 42 from the pin hole 332. More worth mentioning is that in the embodiment, the edge of the limiting seat 41 can be provided with an operation portion 411, which can be a buckle ring for the user to pinch with the hand to realize the disassembly and assembly of the latch 4 and the buckle 3. Of course, the operation portion 411 can be any component for user operation, and is not limited thereto.

[0091] In the embodiment, the buckle 3, the latch 4 and the flexible connecting piece 8 are preferably made of insulating material, so that the short circuit of the solid state disk 1 can be effectively avoided, for example, the three can be integrally injection molded by plastic, but are not limited thereto.

[0092] As preferred, referring to Figure 2 and Figure 7 , the metal main plate 22 of the metal support 2 and the PCB 6 are provided with a Mylar sheet 9, and the profile of the Mylar sheet 9 is matched with the metal main plate 22.

[0093] Based on the insulation and buffering effect of the Mylar sheet 9, the setting makes the sheet metal main plate 22 have as large as possible a force point when fixed on the PCB plate 6, and relatively, the force area of the PCB plate 6 is also increased to a certain extent. If the Mylar sheet 9 is not set, in order to avoid the short circuit of the circuit on the PCB plate 6, the sheet metal main plate 22 needs to be set in the empty area. In this way, compared with the embodiment, the force point of the sheet metal main plate 22 will be less, and the force area of the PCB plate 6 will also be reduced. Therefore, by setting the Mylar sheet 9 between the sheet metal main plate 22 and the PCB plate 6, the supporting effect of the sheet metal main plate 22 on the solid state hard disk can be greatly improved without affecting the use of the circuit of the PCB plate 6, so that the overall structural strength of the fixing member is higher, and the stability is better.

[0094] In addition, by setting the Mylar sheet 9 between the sheet metal main plate 22 and the PCB plate 6, the wear between the sheet metal main plate 22 and the PCB plate 6 due to collision or movement can be reduced, and the service life is long.

[0095] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can also be made, which should be considered as the protection scope of the present application.
