Description

Technical Field

[0001] This utility model relates to a fastener, and more particularly to a horizontally movable elastic fixing device. Background Technology

[0002] Solid-state drives (SSDs) use flash memory to store data and access it digitally. M.2 SSDs are remarkably thin and light, making them ideal for lightweight and portable computers such as laptops, minicomputers, and ultra-thin laptops. M.2 SSDs take up less space than 2.5-inch SSDs or traditional hard drives, and can have capacities up to 2TB.

[0003] The M.2 SSD is inserted into a dedicated slot on the motherboard. Next, align the screws with the recessed holes at the end of the M.2 SSD, and then use a screwdriver to tighten the screws onto the motherboard, securing the end of the M.2 SSD to the motherboard. To remove the M.2 SSD from the slot, you must first remove the screws from the motherboard.

[0004] However, the above method of operation has the following problems: First, it is quite laborious to fix the screws to or remove them from the motherboard using a screwdriver; second, a screwdriver must be prepared in advance, otherwise it is impossible to operate. Utility Model Content

[0005] The main purpose of this invention is to provide a horizontally movable elastic fixing device that can be directly fixed to the motherboard and fix one end of the M.2 solid-state drive in a horizontally movable manner without the need for screwdrivers and screws.

[0006] To achieve the aforementioned objective, this utility model provides a horizontally movable elastic fixing device for fixing one end of an M.2 solid-state drive to a motherboard.

When one end of the M.2 solid-state drive moves downward along the inclined surface and the slider moves horizontally in a first direction along the at least one groove via the at least one track, the elastic member is compressed by the slider to generate elastic force. When one end of the M.2 solid-state drive moves away from the inclined plane, the slider is driven by the lever arm structure and material elasticity of the elastic member. The slider moves horizontally in a second direction along the at least one track and the at least one groove, and the first direction is opposite to the second direction, until one end of the at least one track abuts against the retaining wall of the at least one groove, so that the clamping part presses one end of the M.2 solid-state drive and fixes it on the base.

[0007] In some embodiments, the base includes a fixing seat and a base. The fixing seat has a pin and a positioning pin and a central hole. The pin is inserted into a socket on a motherboard, and the positioning pin is inserted into a positioning hole on the motherboard. The central hole passes through the pin. The inner surface of the pin has multiple channels and a step. The step has multiple stops and multiple limiting blocks. The limiting block has a limiting groove.

[0008] In some embodiments, the positioning post is located outside the insertion post.

[0009] In some embodiments, the insertion post is integrally formed with the positioning post.

[0010] In some embodiments, the groove wall of the at least one slot has a protrusion, and the outer side of the at least one engaging portion has a hook portion, the top of the hook portion abutting against the bottom of the protrusion.

[0011] In some embodiments, one of the second end of the slider and one of the blocking portion have an abutting portion, the elastic member is a spring sheet, one of the first end and one of the second end of the elastic member abuts against the abutting portion, and the other of the first end and the second end of the elastic member is integrally formed with the other of the second end of the slider and the blocking portion.

[0012] In some embodiments, one of the second end of the slider and one of the blocking portion has a contact portion, the elastic member is a spring sheet, one of the first end and one of the second end of the elastic member abuts against the contact portion, the other of the second end of the slider and the blocking portion has a groove, and the other of the first end and the second end of the elastic member has a block that is fitted into the groove.

[0013] In some embodiments, one of the first end and the second end of the elastic member is located above the other of the first end and the second end of the elastic member.

[0014] In some embodiments, the fixing part has a plurality of anti-slip strips disposed on the top of the slider.

[0015] In some embodiments, the base has an opening, and the clamping portion includes at least one first clamping block and one second clamping block. The at least one first clamping block is disposed on at least one side of the first end of the slider and has a first inclined surface. The second clamping block is disposed at the center of the first end of the slider and is located below the at least one first clamping block and extends outward through the opening. The second clamping 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 groove via the at least one track, the elastic member is pressed by the slider. The compression generates elastic force, and the second pressing block moves inward along the opening; wherein, when one end of the M.2 solid-state drive moves away from the first inclined surface, the slider is driven by the lever arm structure of the elastic element and the elasticity of the material, and the slider moves horizontally in the second direction along the at least one track along the at least one groove until one end of the at least one track abuts against the retaining wall of the at least one groove, 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, while the at least one first pressing block presses down one end of a heat sink disposed on the M.2 solid-state drive.

[0016] The advantage of this invention is that the elastic fixing device can be directly fixed to the motherboard, and one end of the M.2 solid-state drive is fixed by the lever arm structure and material elasticity of the positioning member in a horizontal moving manner, thereby achieving an automatic locking effect. The M.2 solid-state drive can be detached from the elastic fixing device of this invention by applying force in the second direction with a finger. No screwdriver or screws are required, and the operation is quite labor-saving and convenient. Attached Figure Description

[0055] The assembly process of the first embodiment of the horizontally movable elastic fixing device 1 of this utility model will be described below.

[0056] like Figure 5As shown, first align the insertion pin 111 with a socket 110 on the motherboard 100 and align the positioning pin 112 with a positioning hole 120 on the motherboard 100. Then, insert the insertion pin 111 into the socket 110 on the motherboard 100 and insert the positioning pin 112 into the positioning hole 120 on the motherboard 100. Finally, the fixing seat 11 is soldered onto the motherboard 100 using reflow soldering technology, so that the fixing seat 11 is fixed on the motherboard 100 and will not rotate or move at all. Figures 1 to 4 As shown, the multiple tracks 213 are moved along the multiple grooves 1242, causing the slider 211 to enter the chamber 124, at which point the clamping part 212 is located above the platform 122 and the protrusion 123. Figures 1 to 4 As shown, the plurality of engaging portions 222 of the baffle 22 are disposed in the plurality of slots 1241, and the tops of the plurality of hook portions 2221 abut against the bottoms of the plurality of protrusions 12411 to prevent the plurality of engaging portions 222 from disengaging from the plurality of slots 1241. The user can clearly see from the plurality of through holes 125 whether the tops of the plurality of hook portions 2221 abut against the bottoms of the plurality of protrusions 12411. Figure 6 and Figure 7 As shown, first align the column 121 with the center hole 113 and align the plurality of guide blocks 1211 with the plurality of channels 1111, then insert the column 121 into the center hole 113 and insert the plurality of guide blocks 1211 into the plurality of channels 1111.

Specifically, when one end of the M.2 solid-state drive 200 moves downward along the inclined surface 2121 and the slider 211 moves horizontally in the first direction along the plurality of tracks 213 and the plurality of grooves 1242, the elastic member 23 is compressed by the abutment portion 2111 to generate elastic force, and the clamping portion 212 moves away from the top of the platform 122. Figure 11A , Figure 11B and Figure 11CAs shown, when one end of the M.2 solid-state drive 200 moves away from the inclined plane 2121, the slider 211 is driven by the lever arm structure and material elasticity of the elastic member 23. The slider 211 moves horizontally in a second direction along the multiple tracks 213 and the multiple grooves 1242, and the first direction is opposite to the second direction, until one end of the multiple tracks 213 abuts against the retaining wall 12421 of the multiple grooves 1242, so that the clamping part 212 returns to the top of the platform 122 to press and fix one end of the M.2 solid-state drive 200 on the platform 122.

[0065] like Figures 14 to 17 As shown, the multiple tracks 213 are moved along the multiple grooves 1242, causing the slider 211 to enter the chamber 124. At this time, the multiple first pressure blocks 2122 are located above the platform 122 and the protrusion 123, and the second pressure block 2123 extends outward through the opening 1231 to above the platform 122. Figures 14 to 17 As shown, the plurality of engaging portions 222 of the baffle 22 are disposed in the plurality of slots 1241, and the tops of the plurality of hook portions 2221 abut against the bottoms of the plurality of protrusions 12411. Figure 18 and Figure 19 As shown, first, align the insertion post 111 with a socket 110 of the motherboard 100A and align the positioning post 112 with a positioning hole 120 of the motherboard 100A. Then, insert the insertion post 111 into the socket 110 of the motherboard 100 and insert the positioning post 112 into the positioning hole 120 of the motherboard 100. Finally, the fixing seat 11A is soldered onto the motherboard 100 using reflow soldering technology, so that the fixing seat 11A is fixed on the motherboard 100 and will not rotate or move at all.

[0066] The following will describe how a third embodiment of the horizontally movable elastic fixing device 1B of this utility model fixes one end of an M.2 solid-state drive 200 to the motherboard 100.

[0067] like Figure 20A , Figure 20B and Figure 20C As shown, one end of the M.2 solid-state drive 200 moves downward along the plurality of first inclined surfaces 21221, causing the slider 211 to move horizontally in a first direction along the plurality of tracks 213 and the plurality of grooves 1242 until one end of the M.2 solid-state drive 200 abuts against the platform 122 and the semi-circular hole 210 aligns with the protrusion 123A. Specifically, when one end of the M.2 solid-state drive 200 moves downward along the plurality of first inclined surfaces 21221 and the slider 211 moves horizontally in the first direction along the plurality of tracks 213 and the plurality of grooves 1242, the elastic member 23 is compressed by the abutment portion 2111 to generate elastic force, the plurality of first pressure blocks 2122 move away from the top of the platform 122, and the second pressure block 2123 moves inward along the opening 1231 away from the top of the platform 122. Figure 21A , Figure 21B and Figure 21CAs shown, when one end of the M.2 solid-state drive 200 moves away from the plurality of first inclined surfaces 21221, the slider 211 is driven by the lever arm structure and material elasticity of the elastic member 23. The slider 211 moves horizontally in a second direction along the plurality of slide grooves 1242 via the plurality of tracks 213 until one end of the plurality of tracks 213 abuts against the retaining wall 12421 of the plurality of slide grooves 1242. This causes the second pressing block 2123 to extend outward through the opening 1231 to the top of the platform 122, pressing and fixing one end of the M.2 solid-state drive 200 onto the platform 122. At the same time, the plurality of first pressing blocks 2122 return to the top of the platform 122, pressing one end of a heat sink 300 mounted on the M.2 solid-state drive 200.

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

[0069] like Figure 22 and Figure 23 As shown, the difference between the fourth embodiment of the elastic fixing device 1C of this utility model and the third embodiment of the elastic fixing device 1B of this utility model is that: a groove 2212 is opened at the bottom of the blocking part 221, and the second end of the elastic member 23 has a block 231, which is embedded in the groove 2212.

[0070] In summary, the elastic fixing devices 1, 1A, 1B, and 1C of this utility model can be directly fixed to the motherboard 100 and 100A. Furthermore, by utilizing the lever arm structure and material elasticity of the positioning member 20, one end of the M.2 solid-state drive 200 is fixed in a horizontally moving manner, thereby achieving an automatic locking effect. Applying force in the second direction with a finger can detach the M.2 solid-state drive 200 from the elastic fixing devices 1, 1A, 1B, and 1C of this utility model, eliminating the need for screwdrivers and screws, making the operation quite labor-saving and convenient.

[0071] The above description is merely a preferred embodiment for explaining the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications or changes made to the present utility model under the same spirit should still be included within the scope of protection intended by the present utility model.
