Detailed description of the specific embodiment

[0028] To achieve the above-mentioned purposes and effects, the technical means and its structure adopted by the present invention will now be described in detail in conjunction with the accompanying drawings for the preferred embodiments of the present invention, and its features and functions are as follows for a complete understanding.

[0029] Please refer to Figures 1 to 6 As shown, they are respectively the three-dimensional view, another perspective three-dimensional view, three-dimensional exploded view, another perspective three-dimensional exploded view, three-dimensional exploded view of the positioning component and another perspective three-dimensional exploded view of the embodiment of the positioning component of the present invention. It can be clearly seen from the figure that the storage module 5 of the present invention includes a preset circuit board 51, and the positioning components with the same structure and arranged in a staggered manner are provided on the first surface and the second surface of the preset circuit board 51. The positioning component includes: a base 1, a fastening member 2, an elastic member 3 and a sliding shaft 4, and the main components and features are described in detail as follows:

[0030] The base 1 includes a receiving groove 10 inside and a slide 101 is formed on two opposite sides of the receiving groove 10. A side guide plate 11 is provided above each of the two slides 101, and a limiting groove 102 is formed between the side guide plate 11 and the slide 101. A stop wall 103 is formed on the rear side of the receiving groove 10 and a positioning body 12 is formed on the front side of the base 1. A positioning unit 13 extends downward from the bottom side of the base 1 and a fixing portion 14 extends laterally.

[0031] The latching member 2 includes a horizontal portion 21 having a push portion 211 at the front end and an operating portion 212 at the rear end. A vertical portion 22 extending downward from the bottom side of the push portion 211 is inserted into the accommodating groove 10 of the base 1, and a connecting plate 23 connected to the vertical portion 22. A positioning block 221 is provided on each side of the vertical portion 22 and is inserted into the limiting groove 102 of the base 1 to form a positioning. An elastic member 3 with two ends that abut against the inner side of the vertical portion 22 and the stop wall 103 is further provided in the accommodating groove 10. A sliding shaft 4 is provided through the connecting plate 23 and the elastic member 3, and the two ends of the sliding shaft 4 are positioned in the two slideways 101 to form a positioning.

[0032] The two side guide plates 11 of the above-mentioned base 1 each form a smooth downward curved guide edge 111 toward the rear side; and the positioning body 12 of the base 1 is composed of a semicircular sheet, and the pre-set interface card 53 is further provided with a semicircular supporting groove 531 on the suspended end that extends into and supports the positioning body 12.

[0033] The positioning unit 13 of the above-mentioned base 1 includes a positioning plate 131 that extends into the wide portion 5111 of a positioning groove 511 of the preset circuit board 51 and slides to the narrow portion 5112 to form a positioning, and a wing plate 132 extending outward from the positioning plate 131. The fixing portion 14 has a lock hole 140 that is located at the fixing groove 512 of the preset circuit board 51 and is provided with a fastener 15 for locking. The fastener 15 is composed of a screw, and the preset circuit board 51 is further provided with an electrical connector 52 on the first surface and the second surface; and the top surface of the wing plate 132 is further provided with a supporting rib 1321 that smoothly abuts against the narrow portion 5112 of the positioning groove 511 of the preset circuit board 51.

[0034] On the top side of the pushing portion 211 of the clamping member 2 described above, there is a guiding inclined surface 2111 for guiding the preset circuit board 51 to rotate downward, and the guiding inclined surface 2111 is in an arc shape. On the bottom side of the pushing portion 211, a limiting surface 2112 is formed. On the bottom side of the operating portion 212 on the other side relative to the pushing portion 211, a sliding surface 2121 is formed; the clamping member 2 extends from the horizontal portion 21 to both sides of the connecting plate 23 to form a limiting block 24 for limiting the abutting side 31 of the elastic member 3, and a limiting space 240 for accommodating the abutting side 31 of the elastic member 3 is formed on the relative inner side of the limiting block 24 and the vertical portion 22; in the connecting plate 23 of the clamping member 2, a shaft hole 230 for the sliding shaft 4 to pass through is further provided, and the two positioning ends 41 of the sliding shaft 4 are positioned in the two sliding grooves 101 of the base 1 to form a positioning.

[0035] The elastic member 3 described above is a torsion spring. A positioning coil 33 is formed by winding in the middle of the elastic member 3, and a threading channel 330 for the sliding shaft 4 to pass through is formed by hollowing in the positioning coil 33. The elastic member 3 forms a deformed side 32 of a metal wire segment with two ends bent at the abutting position against the stop wall 103, and two abutting sides 31 with metal free wire ends are formed at the inner side of the vertical portion 22 of the clamping member 2.

[0036] When assembling the positioning component of the present invention, first insert the two abutting sides 31 of the elastic member 3 into the limiting spaces 240 on both sides of the connecting plate 23 of the fastening member 2, and limit the two abutting sides 31 through the limiting blocks 24. Then, simultaneously align the two through channels 330 of the elastic member 3 with the shaft holes 230 located on the connecting plate 23. Next, press the vertical portion 22, the connecting plate 23, and the elastic member 3 of the fastening member 2 into the accommodating groove 10 of the base 1 from top to bottom at the same time. The positioning blocks 221 on both sides of the vertical portion 22 slide into the two limiting grooves 102 of the base 1 towards the positioning body 12 to form positioning. Then, make the abutting side 31 of the elastic member 3 abut against the inner side of the vertical portion 22 and the deformed side 32 abut against the stop wall 103. Moreover, the two through channels 330 of the elastic member 3 and the shaft holes 230 of the connecting plate 23 must be simultaneously aligned with the two sliding channels 101 of the base 1. Then, penetrate the sliding shaft 4 through the two sliding channels 101, the two through channels 330, and the shaft holes 230, and the two positioning ends 41 of the sliding shaft 4 are positioned in the two sliding channels 101 to form positioning, thereby completing the assembly of the positioning component through the above steps. When installing the positioning component on the circuit board 51 of the storage module 5, first align the positioning plate 131 and the wing plate 132 of the base 1 with the positioning groove 511 of the circuit board 51 and insert them downward through the wide portion 5111. Then, apply force to horizontally push the base 1 so that the positioning plate 131 slides from the wide portion 5111 to the narrow portions 5112 at both places. At this time, the top surface of the wing plate 132 abuts upward against the narrow portions 5112 on the bottom side of the circuit board 51, and the locking holes 140 of the fixing portion 14 are aligned with the fixing grooves 512 of the preset circuit board 51 and locked through the fasteners 15, thus completing the assembly of the first side of the circuit board 51 and the positioning component. The assembly of the second side of the circuit board 51 and another positioning component can also be completed by referring to the above process, and the two positioning components are arranged in a staggered manner. At the same time, the electrical connectors 52 and the interface cards 53 provided on the two surfaces of the circuit board 51 are also arranged in a staggered manner. Although this structural design slightly increases the length of the used circuit board 51, the overall thickness of the storage module 5 can be reduced, which has better flexibility for being assembled in the limited space of a server or an industrial personal computer (IPC).

[0037] Please refer to Figures 7 to 9As shown in the figures, they are the first, second, and third schematic diagrams of the operation of the storage module of the present invention during installation. On the circuit board 51 of the storage module 5, there is an electrical connector 52 with an obliquely docking space. The interface card 53 composed of an M.2 specification solid-state drive (SSD) is obliquely inserted into the docking space (not labeled) of the electrical connector 52 and electrically connected to a plurality of conductive terminals (not labeled). When the edge of the board of the interface card 53 is suspended, a positioning component is required for fixation. When the suspended edge of the interface card 53 is to be positioned in the positioning component, the electrical connector 52 is first used as the rotation axis, and the interface card 53 is rotated towards the pushing portion 211 of the fastening member 2. The pushing portion 211 retracts under the stress of the interface card 53 in the horizontal direction and drives the sliding shaft 4 to move towards the rear side of the base 1 in the two sliding channels 101, and the elastic member 3 is compressed and deformed, so that the interface card 53 is vertically rotated downward into the bottom side of the limiting surface 2112 of the pushing portion 211. The base 1 has a positioning body 12 in the shape of a semi-circular sheet corresponding to the limiting surface 2112, and the positioning body 12 is used to hold and position the holding groove 531 of the interface card 53. At the same time, when the fastening member 2 removes the pushing force of the interface card 53, the elastic member 3 generates an elastic restoring force, driving the pushing portion 211, the elastic member 3, and the sliding shaft 4 to return to their original positions, and the top surface of the interface card 53 is limited by the limiting surface 2112 of the fastening member 2; the side and bottom surfaces of the interface card 53 are received at the periphery of the positioning body 12, and the positioning structure of the positioning component and the interface card 53 is completed through the above steps.

[0038] Please refer to Figure 10 As shown in the figure, it is a schematic diagram of the operation of the storage module of the present invention during disassembly. When the positioning component and the interface card 53 are to be disassembled, first apply a force to the operation portion 212 of the fastening member 2 towards the rear side of the base 1, so that the sliding shaft 4 moves a predetermined distance in the sliding channel 101, and the elastic member 3 generates a large amount of compression, and the sliding surface 2121 at the bottom of the operation portion 212 slides along the inclined guiding edges 111 of the two guiding plates 11 towards the rear side of the base 1. At this time, the interface card 53 is warped upward at the end face far from the electrical connector 52 due to the elastic restoring force of the internal conductive terminals of the electrical connector 52. After the holding groove 531 of the interface card 53 rotates upward and disengages from the positioning body 12 and the pushing portion 211, the interface card 53 can be obliquely withdrawn from the electrical connector 52. Then, remove the force applied to the operation portion 212 of the fastening member 2, drive the pushing portion 211, the elastic member 3, and the sliding shaft 4 to return to their original positions, and make the positioning block 221 of the fastening member 2 slide into the two limiting grooves 102 of the base 1, so as to achieve the purpose of separating the positioning component and the interface card 53. Then, after removing the fastener 15 with a hexagonal groove on the top surface by a hand tool (such as an Allen wrench), apply a force in the horizontal direction to the positioning component and make the positioning plate 131 slide from the narrow portion 5112 of the positioning groove 511 to the wide portion 5111, and then the positioning component can be disengaged from the circuit board 51 upward.

[0039] The main features of the present invention are as follows: Electrical connectors 52, interface cards 53 and positioning components are provided on both sides of the circuit board 51 of the storage module 5. The two positioning components are locked to the circuit board 51 by fasteners 15 to increase stability. At the same time, the two positioning components are arranged in a staggered manner in the circuit board 51 to reduce the overall thickness of the storage module 5. The two interface cards 53 are respectively positioned on the upper and lower layers of the circuit board 51 and are electrically connected through the corresponding electrical connectors 52 to form a high-density stacked storage capacity. Through this circuit layout form, circuits can be arranged on both sides of the circuit board 51 to reduce the use of Plating Through Holes (PTH). In addition to simplifying the circuit complexity, it can further reduce the overall manufacturing cost of the storage module 5. The present invention is applied in the assembly field of high-capacity storage devices for servers or industrial computers and has excellent practicability.

[0040] The above are only the preferred embodiments of the present invention, and thus do not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the content of the specification and drawings of the present invention should be equally included in the patent scope of the present invention.
