Technical Field

[0001] The present invention relates to a fastener, and particularly to an elastic fixing device capable of horizontal movement. Background Art

[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, align the screw with the concave hole at the end of the M.2 solid state drive, and use a screwdriver to fix the screw on the motherboard, so that the screw fixes the end of the M.2 solid state drive on 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 on the motherboard or remove it from the motherboard; Second, a screwdriver must be prepared in advance, otherwise the operation cannot be carried out.

[0015] In some embodiments, an opening is formed in the base, the clamping portion includes at least one first pressing block and a second pressing block. The at least one first pressing block is disposed on at least one side of the first end of the slider and has a first inclined surface. The second pressing block is disposed at the center of the first end of the slider and is located below the at least one first pressing block and extends outward through the opening. The second pressing block has a second inclined surface. When one end of the M.2 solid state drive moves downward along the first inclined surface and the slider moves horizontally in the first direction along the at least one chute through the at least one track, the elastic member is compressed by the slider to generate an elastic force, and the second pressing block moves inward along the opening. When one end of the M.2 solid state drive is away from the first inclined surface, the slider is driven by the force arm structure and material elasticity of the elastic member. The slider moves horizontally in the second direction along the at least one chute through the at least one track until one end of the at least one track abuts against the retaining wall of the at least one chute, so that the second pressing block extends outward through the opening to press and fix one end of the M.2 solid state drive on the base, and at the same time the at least one first pressing block presses one end of a heat sink disposed on the M.2 solid state drive.

[0016] The effect of the present invention is that the elastic fixing device of the present invention can be directly fixed on the main board, and one end of the M.2 solid state drive is fixed in a horizontal movement manner through the force arm structure and material elasticity of the positioning member, so as to achieve the effect of automatic buckling.

The plurality of through holes 125 communicate with the plurality of clamping grooves 1241 respectively and their positions correspond to the plurality of convex portions 12411.

[0053] The positioning member 20 includes a fixing portion 21, a baffle 22 and an elastic member 23. The fixing portion 21 has a slider 211, a clamping portion 212, two tracks 213 and a plurality of anti-slip strips 214. The slider 211 is disposed in the chamber 124. The clamping portion 212 is disposed at a first end of the slider 211 and is located above the platform 122 and the convex post 123 and has an inclined surface 2121. A second end of the slider 211 has an abutting portion 2111.

Specifically, the abutting portion 2111 is located above the bottom of the blocking portion 221, and the second end of the elastic member 23 is integrally formed with the bottom of the blocking portion 221, so that the first end of the elastic member 23 is located above the second end of the elastic member 23.

[0054] Preferably, the overall material of the base 10 and the positioning member 20 can be metal or plastic. In some embodiments, a part of the material of the base 10 and the positioning member 20 can be metal, and another part of the material of the base 10 and the positioning member 20 can be plastic. For example, the material of the base 10 and the fixing portion 21 of the positioning member 20 is metal, and the baffle 22 and the elastic member 23 of the positioning member 20 are 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 metal material part of the base 10 and the positioning member 20 can be a metal part made by Metal Powder Injection Molding Technology (MIM), which has a quite good texture and a smooth surface.

[0055] The following will describe the assembly process of the first embodiment of the horizontally movable elastic fixing device 1 of the present invention.

[0056] As Figure 5As shown in the figure, first align the insertion post 111 with a jack 110 of a main board 100 and align the positioning post 112 with a positioning hole 120 of the main board 100. Then insert the insertion post 111 into the jack 110 of the main board 100 and insert the positioning post 112 into the positioning hole 120 of the main board 100. Finally, 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 Figures 1 to 4 shown in the figure, move the plurality of tracks 213 along the plurality of chutes 1242 so that the slider 211 enters the chamber 124. At this time, the buckling part 212 is located above the platform 122 and the convex post 123. As Figures 1 to 4 shown in the figure, arrange the plurality of engaging parts 222 of the baffle 22 in the plurality of card slots 1241 and make the tops of the plurality of hook parts 2221 abut against the bottoms of the plurality of convex parts 12411 to prevent the plurality of engaging parts 222 from disengaging from the plurality of card slots 1241. The user can clearly see from the plurality of through holes 125 whether the tops of the plurality of hook parts 2221 abut against the bottoms of the plurality of convex parts 12411. As Figure 6 and Figure 7 shown in the figure, first align the column body 121 with the central hole 113 and align the plurality of guiding blocks 1211 with the plurality of channels 1111. Then insert the column body 121 into the central hole 113 and insert the plurality of guiding blocks 1211 into the plurality of channels 1111. As Figure 6 、 Figure 8 and Figure 9 shown in the figure, rotate the base 12 counterclockwise until the plurality of convex blocks 12111 are respectively located in the plurality of limiting grooves 11141, so that the base 12 is fixed to the fixing base 11.

[0057] The following will illustrate how the first embodiment of the horizontally movable elastic fixing device 1 of the present invention fixes one end of an M.2 solid state drive 200 to a main board 100.

[0058] As Figure 10A 、 Figure 10B and Figure 10C shown in the figure, one end of the M.2 solid state drive 200 moves downward along the inclined surface 2121, so that the slider 211 horizontally moves in a first direction along the plurality of chutes 1242 through the plurality of tracks 213 until one end of the M.2 solid state drive 200 abuts against the platform 122 and the semi-circular hole 210 is aligned with the convex post 123. Specifically, when one end of the M.2 solid state drive 200 moves downward along the inclined surface 2121 and the slider 211 horizontally moves in the first direction along the plurality of chutes 1242 through the plurality of tracks 213, the elastic member 23 is compressed by the abutting portion 2111 to generate an elastic force, and the buckling portion 212 moves away from above the platform 122. As Figure 11A 、 Figure 11B and Figure 11CAs shown, when one end of the M.2 solid-state drive 200 is far from the inclined surface 2121, the slider 211 is driven by the lever structure and material elasticity of the elastic member 23. The slider 211 horizontally moves in a second direction along the plurality of chutes 1242 through the plurality of rails 213, and the first direction is opposite to the second direction until one end of the plurality of rails 213 abuts against the retaining walls 12421 of the plurality of chutes 1242, so that the buckling portion 212 returns above the platform 122 to press and fix one end of the M.2 solid-state drive 200 on the platform 122.

[0059] When the user wants to remove the M.2 solid-state drive 200 from the first embodiment of the horizontally movable elastic fixing device 1 of the present invention, the user's finger can press on the plurality of anti-slip strips 214 and apply a force in the first direction, so that the slider 211 horizontally moves in the first direction along the plurality of chutes 1242 through the plurality of rails 213. At this time, one end of the M.2 solid-state drive 200 is no longer pressed by the buckling portion 212, so that the M.2 solid-state drive 200 can be detached from the first embodiment of the horizontally movable elastic fixing device 1 of the present invention.

[0060] In some embodiments, the first end of the elastic member 23 is integrally formed with the second end of the slider 211. The bottom of the blocking portion 221 has an abutting portion 2111, and the second end of the elastic member 23 abuts against the abutting portion 2111, so that the first end of the elastic member 23 is located above the second end of the elastic member 23. In some embodiments, the bottom of the second end of the slider 211 has an abutting portion 2111, and the abutting portion 2111 is located below the top of the blocking portion 221. The first end of the elastic member 23 abuts against the abutting portion 2111, and the second end of the elastic member 23 is integrally formed with the top of the blocking portion 221, so that the first end of the elastic member 23 is located below the second end of the elastic member 23.

Each first pressing block 2122 has a first inclined surface 21221. The second pressing block 2123 is disposed at the center of the first end of the slider 211 and below the plurality of first pressing blocks 2122 and extends outwards through the opening 1231 above the platform 122. The second pressing block 2123 has a second inclined surface 21231.

[0064] The following will describe the assembly process of the third embodiment of the horizontally movable elastic fixing device 1B of the present invention.

[0065] AsFigures 14 to 17 As shown, move the multiple tracks 213 along the multiple chutes 1242 so that the slider 211 enters the chamber 124. At this time, the multiple first pressing blocks 2122 are located above the platform 122 and the convex posts 123, and the second pressing block 2123 extends outwards through the opening 1231 to above the platform 122. As Figures 14 to 17 As shown, arrange the multiple engaging portions 222 of the baffle 22 in the multiple card slots 1241 and make the tops of the multiple hook portions 2221 abut against the bottoms of the multiple convex portions 12411. As Figure 18 and Figure 19 As shown, first align the insertion post 111 with a jack 110 of a main board 100A and align the positioning post 112 with a positioning hole 120 of the main board 100A. Then insert the insertion post 111 into the jack 110 of the main board 100 and insert the positioning post 112 into the positioning hole 120 of the main board 100. Finally, the fixing seat 11A is soldered onto the main board 100 through reflow soldering technology, so that the fixing seat 11A is fixed on the main board 100 and will not rotate or move at all.

[0066] The following will illustrate how the third embodiment of the horizontally movable elastic fixing device 1B of the present invention fixes one end of an M.2 solid state drive 200 to the main board 100.

[0067] As Figure 20A 、 Figure 20B and Figure 20C As shown, one end of the M.2 solid state drive 200 moves downward along the multiple first inclined surfaces 21221, so that the slider 211 horizontally moves in a first direction along the multiple chutes 1242 through the multiple tracks 213 until one end of the M.2 solid state drive 200 abuts against the platform 122 and the semi-circular hole 210 is aligned with the convex post 123A. Specifically, when one end of the M.2 solid state drive 200 moves downward along the multiple first inclined surfaces 21221 and the slider 211 horizontally moves in the first direction along the multiple chutes 1242 through the multiple tracks 213, the elastic member 23 is compressed by the abutting portion 2111 to generate an elastic force. The multiple first pressing blocks 2122 move away from above the platform 122, and the second pressing block 2123 moves inwards along the opening 1231 to move away from above the platform 122. As Figure 21A 、 Figure 21B and Figure 21CAs shown, when one end of the M.2 solid-state drive 200 is far from the plurality of first inclined surfaces 21221, the slider 211 is driven by the lever structure and material elasticity of the elastic member 23. The slider 211 horizontally moves in a second direction along the plurality of tracks 213 and the plurality of sliding grooves 1242 until one end of the plurality of tracks 213 abuts against the retaining walls 12421 of the plurality of sliding grooves 1242. In this way, the second pressing block 2123 extends outwards through the opening 1231 above the platform 122 to press and fix one end of the M.2 solid-state drive 200 on the platform 122. At the same time, the plurality of first pressing blocks 2122 return above the platform 122 to press one end of a heat sink 300 provided on the M.2 solid-state drive 200.

[0068] When the user wants to remove the M.2 solid-state drive 200 from the third embodiment of the horizontally movable elastic fixing device 1B of the present invention, the user's finger can press on the plurality of anti-slip strips 214 and apply a force in the first direction, so that the slider 211 horizontally moves in the first direction along the plurality of tracks 213 and the plurality of sliding grooves 1242. At this time, one end of the M.2 solid-state drive 200 is no longer pressed by the second pressing block 2123, and one end of the heat sink 300 is no longer pressed by the plurality of first pressing blocks 2122, so that the M.2 solid-state drive 200 and the heat sink 300 can be detached from the third embodiment of the elastic fixing device 1B of the present invention.

[0069] As Figure 22 and Figure 23 As shown, the difference between the fourth embodiment of the elastic fixing device 1C of the present invention and the third embodiment of the elastic fixing device 1B of the present invention is that: an embedding groove 2212 is formed at the bottom of the blocking portion 221, and the second end of the elastic member 23 has a block 231, and the block 231 is embedded in the embedding groove 2212.

[0070] In summary, the elastic fixing devices 1, 1A, 1B, and 1C of the present invention can be directly fixed on the main boards 100 and 100A, and fix one end of the M.2 solid-state drive 200 in a horizontally movable manner through the lever structure and material elasticity of the positioning member 20, so as to achieve the effect of automatic buckling. By applying a force in the second direction with the finger, the M.2 solid-state drive 200 can be detached from the elastic fixing devices 1, 1A, 1B, and 1C of the present invention without a screwdriver and screws, and the operation is quite labor-saving and convenient.

[0071] 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 related to the present invention made in the same inventive spirit should still be included in the scope intended to be protected by the present invention.
