[0002] A solid state drive (SSD) uses flash memory to store data and accesses data digitally. The M.2 specification solid state drive is quite thin and light, making the M.2 solid state drive an ideal choice for lightweight and portable computers such as laptops, mini computers, and ultra-thin laptops. The M.2 solid state drive occupies less space than a 2.5-inch solid state drive or a traditional hard drive, and the capacity can reach up to 2TB at most.

[0003] The M.2 solid state drive can be inserted into a dedicated slot on the motherboard. Then, the screw is aligned with the concave hole at the end of the M.2 solid state drive, and then a screwdriver is used to fix the screw to the motherboard, so that the screw fixes the end of the M.2 solid state drive to the motherboard. If you want to pull out the M.2 solid state drive from the slot, you have to first remove the screw from the motherboard.

[0004] However, the above operation method has the following several problems: First, it is quite laborious to use a screwdriver to fix the screw to the motherboard or remove it from the motherboard; Second, a screwdriver must be prepared in advance, otherwise the operation cannot be carried out.

Detailed implementation manner

[0053] The following will make a more detailed description of the implementation manner of the present invention in conjunction with the drawings and component symbols, so that those skilled in the art can implement it after studying this specification.

[0054] As Figure 1 、 Figure 2 and Figure 3 shown, the present invention provides an elastically fixed device 1 that can be vertically rotated, including a base 10 and a positioning member 20.

[0055] The base 10 includes a fixing seat 11 and a base 12. The fixing seat 11 has an insertion post 111 and a positioning post 112 and is provided with a central hole 113. The insertion post 111 is cylindrical and is located at the center of the bottom of the fixing seat 11. The positioning post 112 is located outside the insertion post 111. The central hole 113 penetrates the insertion post 111. The inner side surface of the insertion post 111 has a plurality of channels 1111 and a step 1112 (see Figure 8 and Figure 9 ), the step 1112 has a plurality of stoppers 1113 and a plurality of limiting blocks 1114 (see Figure 8 and Figure 9), the limiting block 1114 has a limiting groove 11141. The base 12 has a cylinder 121, two arc surfaces 122, two blocking portions 123, a platform 124, and a convex post 125, and a cavity 126 and two pivot holes 127 are formed. The cylinder 121 is located at the center of the bottom of the base 12 and is inserted into the central hole 113. The outer side surface of the cylinder 121 has a plurality of guiding blocks 1211. The plurality of guiding blocks 1211 are close to the bottom of the cylinder 121, and each guiding block 1211 has a convex block 12111. The two arc surfaces 122 and the two blocking portions 123 are located on both sides of the top of the base 12. The two blocking portions 123 are respectively arranged at one ends of the two arc surfaces 122. The platform 124 is located on the top of the base 12, and the convex post 125 is arranged on the platform 124. The cavity 126 penetrates through the top of the base 12, one side of the base 12, and the convex post 125. The inner side wall of the cavity 126 has an arc surface 1261 (see Figure 7 ). The two pivot holes 127 communicate with the cavity 126 and penetrate through both sides of the base 12 respectively.

[0056] The positioning member 20 includes a pivot joint portion 21, a fixing portion 22, and an elastic member 23. The pivot joint portion 21 is cylindrical and is arranged in the cavity 126. The shaft portions 211 at both ends of the pivot joint portion 21 are respectively pivotally arranged in the two pivot holes 127. The fixing portion 22 includes a dial block 221 and a pressing portion 222. The dial block 221 is arranged on the pivot joint portion 21 and is located above the base 12. The pressing portion 222 is arranged at one end of the dial block 221 and has an inclined surface 2221. The dial block 221 has a groove 2211, two arc surfaces 2212, and two flat surfaces 2213, and a clamping groove 2214 is formed (see Figure 7 ). The groove 2211 is located at the top of the dial block 221. The two arc surfaces 2212 are located on both sides of the bottom of the dial block 221. The two flat surfaces 2213 are respectively arranged at one ends of the two arc surfaces 2212. The clamping groove 2214 is located at the center of the bottom of the dial block 221 and extends radially. The two arc surfaces 2212 of the dial block 221 abut against the two arc surfaces 122 of the base 12. The elastic member 23 is a spring piece and has an arc-shaped portion. The top end of the elastic member 23 is embedded in the clamping groove 2214, and the bottom end of the elastic member 23 abuts against the base 12.

[0057] Preferably, the materials of the base 10 and the positioning member 20 can be metal or plastic. However, the present invention is not limited thereto, and any material suitable for the base 10 and the positioning member 20 is covered by the scope of the present invention. Among them, the base 10 and the positioning member 20 can be metal parts made by metal powder injection molding technology, which are quite textured and have a smooth surface.

[0058] The following will describe the assembly process of the first embodiment of the elastic fixing device 1 of the present invention.

[0059] AsFigure 4 As shown, first, the insertion post 111 aligns with a jack 110 of a main board 100, and the positioning post 112 aligns with a positioning hole 120 of the main board 100. Then, the insertion post 111 is inserted into the jack 110 of the main board 100, the positioning post 112 is inserted into the positioning hole 120 of the main board 100, and the fixing base 11 is soldered onto the main board 100 through reflow soldering technology, so that the fixing base 11 is fixed on the main board 100 and will not rotate or move at all. As Figure 5 As shown, first, the top end of the elastic member 23 is embedded in the slot 2214, and then the positioning member 20 is disposed on the base 12. As Figure 6 and Figure 7 As shown, the base 12 is combined with the fixing base 11, so that the elastic fixing device 1 is fixed on the main board 100. As Figure 8 As shown, when the base 12 rotates horizontally to the left and the plurality of guiding blocks 1211 are respectively located in the plurality of channels 1111, the plurality of guiding blocks 1211 disengage from the plurality of limiting blocks 1114. As Figure 9 As shown, when the base 12 rotates horizontally to the right, the plurality of bumps 12111 are respectively located in the plurality of limiting slots 11141, so that the base 12 is fixed to the fixing base 11.

[0060] The following will illustrate how the first embodiment of the elastic fixing device 1 fixes one end of an M.2 solid state drive 200 to the main board 100.

[0061] As Figure 10A and Figure 10B As shown, one end of the M.2 solid state drive 200 moves downward along the inclined surface 2221, so that the dial block 221 rotates downward along the vertical direction through the pivot portion 21 until one end of the M.2 solid state drive 200 abuts against the platform 124 and the semi-circular hole 210 aligns with the convex post 125. Specifically, when one end of the M.2 solid state drive 200 moves downward along the inclined surface 2221 and the dial block 221 rotates downward along the vertical direction through the pivot portion 21, the pivot portion 21 rotates smoothly along the arc surface 1261 of the inner side wall of the chamber 126, and the two arc surfaces 2212 of the dial block 221 move smoothly along the two arc surfaces 122 of the base 12. At this time, the elastic member 23 is compressed by the dial block 221 to generate elastic force until the two flat surfaces 2213 respectively contact the two blocking portions 123 to prevent the dial block 221 from rotating excessively and the elastic member 23 from being excessively squeezed to generate excessive elastic force and eject the dial block 221 outward. As Figure 11A and Figure 11BAs shown, when one end of the M.2 solid state drive 200 is far from the inclined surface 2221, the elastic force of the elastic member 23 drives the dial block 221 to rotate upward along the vertical direction through the pivot portion 21. The pivot portion 21 rotates smoothly along the arc surface 1261 of the inner side wall of the chamber 126, and the two arc surfaces 2212 of the dial block 221 move smoothly along the two arc surfaces 122 of the base 12 until the pressing portion 222 abuts against the convex column 125, so that the pressing portion 222 presses and fixes one end of the M.2 solid state drive 200 on the platform 124.

[0062] When the user wants to remove the M.2 solid state drive 200 from the elastic fixing device 1 of the present invention, the user's finger can deeply sink into the groove 2211 and press the dial block 221, so that the dial block 221 rotates downward along the vertical direction through the pivot portion 21. At this time, one end of the M.2 solid state drive 200 is no longer pressed by the pressing portion 222, so that the M.2 solid state drive 200 can be detached from the elastic fixing device 1 of the present invention.

[0063] As Figure 12 and Figure 13 shown, the structural difference between the second embodiment of the elastic fixing device 1A of the present invention and the first embodiment of the elastic fixing device 1 of the present invention is as follows: First, a receiving groove 2215 is formed in the dial block 221A (see Figure 16B ); Second, the elastic member 23A is a spring and is located in the receiving groove 2215. The top end of the elastic member 23A abuts against the top wall of the receiving groove 2215, and the bottom end of the elastic member 23A abuts against the base 12.

[0064] As Figure 4 , Figure 8 , Figure 9 , Figure 14 and Figure 15 shown, the assembly processes of the second embodiment and the first embodiment are exactly the same.

[0065] As Figure 16A , Figure 16B , Figure 17A and Figure 17B shown, the ways of fixing one end of the M.2 solid state drive 200 to the main board 100 in the second embodiment and the first embodiment are exactly the same.

[0066] As Figure 18 and Figure 19 shown, the difference between the third embodiment of the elastic fixing device 1B of the present invention and the first embodiment of the elastic fixing device 1 of the present invention is as follows: First, the top end of the elastic member 23B is integrally formed with the bottom end of the dial block 221B; Second, the elastic member 23B is arc-shaped.

[0067] As Figure 4 , Figure 8 , Figure 9 ,Figure 20 and Figure 21 As shown in Figure 21 , the assembly process of the third embodiment is exactly the same as that of the first embodiment.

[0068] As Figure 22A , Figure 22B , Figure 23A and Figure 23B As shown in Figure 23B , the third embodiment and the first embodiment fix one end of the M.2 solid-state drive 200 to the motherboard 100 in exactly the same way.

[0069] As Figure 24 , Figure 25 and Figure 26 As shown in Figure 26 , the difference between the fourth embodiment of the elastic fixing device 1C of the present invention and the first embodiment of the elastic fixing device 1 of the present invention is as follows: First, the fixing base 11A and the base 12 are integrally formed, the plug post 111A is in a gourd shape, and an opening 1251 is formed in the convex post 125A; Second, a shaft hole 212 is formed in the pivoting portion 21A, and a shaft portion 211A is inserted into the shaft hole 212; Third, the pressing portion 222A includes two first pressing blocks 2222 and a second pressing block 2223. The two first pressing blocks 2222 are respectively disposed on both sides of one end of the dial block 221C. Each first pressing block 2222 has a first inclined surface 22221. The second pressing block 2223 is disposed at the center of one end of the dial block 221C and below the two first pressing blocks 2222. The second pressing block 2223 has a second inclined surface 22231.

[0070] The following will describe the assembly process of the fourth embodiment of the elastic fixing device 1C of the present invention.

[0071] As Figure 27 shown in Figure 27 , first embed the top end of the elastic member 23 in the card slot 2214, then set the positioning member 20 on the base 12, and finally insert the shaft portion 211A through the pivot hole 127 and into the shaft hole 212. As Figure 28 and Figure 29 shown in Figure 29 , first, align the plug post 111A with a jack 110A on a motherboard 100A; then, insert the plug post 111A into the jack 110A on the motherboard 100A, and the base 12 is soldered to the motherboard 100A through reflow soldering technology, so that the base 12 is fixed on the motherboard 100A and will not rotate or move at all.

[0072] The following will describe how the fourth embodiment of the elastic fixing device 1C fixes one end of an M.2 solid-state drive 200 to the motherboard 100A.

[0073] As Figure 30A and Figure 30BAs shown, one end of the M.2 solid state drive 200 moves downward along the two first inclined surfaces 22221, such that the toggle block 221C rotates downward in the vertical direction via the pivoting portion 21A until one end of the M.2 solid state drive 200 abuts against the platform 124 and the semi-circular holes 210 are aligned with the protruding posts 125A. Specifically, when one end of the M.2 solid state drive 200 moves downward along the two first inclined surfaces 22221 and the toggle block 221C rotates downward in the vertical direction via the pivoting portion 21A, the pivoting portion 21A rotates smoothly along the arc surface 1261 of the inner sidewall of the chamber 126, and the two arc surfaces 2212 of the toggle block 221C move smoothly along the two arc surfaces 122 of the base 12. At this time, the elastic member 23 is compressed by the toggle block 221C to generate an elastic force until the two flat surfaces 2213 contact the two blocking portions 123 respectively, preventing the toggle block 221C from rotating excessively and the elastic member 23 from being excessively squeezed to generate an excessive elastic force and ejecting the toggle block 221C outward. As Figure 31A and Figure 31B shown, when one end of the M.2 solid state drive 200 moves away from the two first inclined surfaces 22221, the elastic force of the elastic member 23 drives the toggle block 221C to rotate upward in the vertical direction via the pivoting portion 21A. The pivoting portion 21A rotates smoothly along the arc surface 1261 of the inner sidewall of the chamber 126, and the two arc surfaces 2212 of the toggle block 221C move smoothly along the two arc surfaces 122 of the base 12 until the second pressing block 2223 enters the opening 1251, such that the second pressing block 2223 presses and fixes one end of the M.2 solid state drive 200 on the platform 124, and at the same time the two first pressing blocks 2222 press one end of a heat sink 300 provided on the M.2 solid state drive 200.

[0074] When the user wants to remove the M.2 solid state drive 200 and the heat sink 300 from the elastic fixing device 1C of the present invention, the user's finger can deeply penetrate into the groove 2211 and press the toggle block 221C, such that the toggle block 221C rotates downward in the vertical direction via the pivoting portion 21A. At this time, one end of the M.2 solid state drive 200 is no longer pressed by the second pressing block 2223, and one end of the heat sink 300 is no longer pressed by the two first pressing blocks 2222, enabling the M.2 solid state drive 200 and the heat sink 300 to be detached from the elastic fixing device 1C of the present invention.

[0075] As Figure 32 shown, the difference between the fifth embodiment of the elastic fixing device 1D of the present invention and the fourth embodiment of the elastic fixing device 1C of the present invention is that: the elastic member 23 is replaced with an elastic member 23A.

[0076] As Figure 33 、 Figure 34 and Figure 35As shown in the figure, the difference between the sixth embodiment of the elastic fixing device 1E and the fourth embodiment of the elastic fixing device 1C is as follows: First, two card slots 2214A are formed in the dial block 221D. The two card slots 2214A are located on both sides of the bottom of the dial block 221D and extend radially. The top end of the elastic member 23C has two latch blocks 231, and the two latch blocks 231 are respectively embedded in the two card slots 2214A. Second, an embedding groove 2216 is formed in the dial block 221D. The embedding groove 2216 is located at the bottom of the dial block 221D and extends axially. The top end of the elastic member 23C has an embedding block 232, and the embedding block 232 is embedded in the embedding groove 2216, so as to improve the fixing effect of the top end of the elastic member 23C.

[0077] In summary, the elastic fixing devices 1, 1A, 1B, 1C, 1D, and 1E of the present invention can be directly fixed on the main boards 100 and 100A, and one end of the M.2 solid-state drive 200 is fixed in a vertically rotating manner by means of the lever structure and material elasticity of the positioning member 20, so as to achieve the effect of automatic buckling. Pressing with a finger can disengage the M.2 solid-state drive 200 from the elastic fixing devices 1, 1A, 1B, 1C, 1D, and 1E of the present invention without a screwdriver and screws, and the operation is quite labor-saving and convenient.

[0078] The above are only preferred embodiments for explaining the present invention, and are not intended to limit the present invention in any form. Therefore, any modification or change to the present invention made under the same inventive spirit should still be included in the scope intended to be protected by the present invention.
