Description

Horizontally rotatable elastic fixing device

The present invention relates to a fastener, specifically a horizontally rotatable elastic fixing device for securing one end of an M.2 solid-state drive to a motherboard.

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

The M.2 SSD can be inserted into the dedicated slot on the motherboard. Then, align the screw with the recessed hole at the end of the M.2 SSD and use a screwdriver to tighten the screw into the motherboard, securing the end of the M.2 SSD to the motherboard. To remove the M.2 SSD from the slot, first remove the screw from the motherboard.

However, this method has several problems: First, using a screwdriver to secure or remove screws from the motherboard is laborious; second, the screwdriver must be prepared in advance; otherwise, the operation will be impossible.

The primary purpose of this invention is to provide a horizontally rotatable elastic fixing device that can be directly fixed to the motherboard and horizontally rotated to secure one end of an M.2 solid-state drive without the need for a screwdriver or screws.

To achieve the aforementioned objectives, the present invention provides a horizontally rotatable elastic fixing device for securing one end of an M.2 solid-state drive to a motherboard. The elastic fixing device includes a base and a positioning member. The base is secured to the motherboard. The positioning member is disposed on the base and rotates relative to the base in a first horizontal direction and a second horizontal direction, the first horizontal direction being opposite to the second horizontal direction. When the positioning member rotates in the first horizontal direction, it generates an elastic force. The elastic force of the positioning member drives the positioning member to rotate in the second horizontal direction, thereby securing the one end of the M.2 solid-state drive to the motherboard.

In some embodiments, the base includes a latch and a first slide block and a latch groove, the positioning member includes a head, a rod and an elastic member, the head has a latch portion and a fixed portion, the rod is arranged at the bottom of the head and has an axial hole and a first slide groove, the latch passes through the axial hole and its top is fixed to the latch portion, the first slide block is arranged in the first slide groove, a first end of the elastic member is arranged at the bottom of the head, the elastic member surrounds the rod, and a first end of the elastic member is fixed to the first slide groove. Each end has a protrusion that is inserted into the slot. When the head and the rod rotate in the first horizontal direction, the elastic member is compressed to generate an elastic force, causing the first slider to move along the first slot to a first end of the first slot. The elastic force of the elastic member drives the head and the rod to rotate in the second horizontal direction, causing the first slider to move along the first slot to a second end of the first slot, thereby securing one end of the M.2 solid-state drive to the motherboard.

In some embodiments, the base includes a fixing base and a base. The fixing base is used to be fixed to the motherboard.

Subsequently, the inserts 1111 are inserted into the socket 110 on the motherboard 100, while the second protrusions 11115 engage the bottom surface of the motherboard 100 and the positioning post 112 is inserted into the positioning hole 120 on the motherboard 100. This secures the mounting base 11 to the motherboard 100, preventing rotation and movement.

Figure 10A is a bottom view of the first embodiment of the present invention installed on a motherboard 100, with the base 12 rotated in a first horizontal direction relative to the mounting base 11. Figure 10B is a cross-sectional view of Figure 10A. As shown in Figures 10A and 10B, during the insertion of the column 123 into the center hole 113, the guide blocks 1232 align with the grooves 1112, thereby guiding the column 123 smoothly into the center hole 113. When the base 12 rotates in the first horizontal direction and the blocks 1231 and the guide blocks 1232 are respectively located in the grooves 1112, the second slide blocks 124 move along the second slide grooves 114 to a first end 1141 of the second slide grooves 114. The blocks 1231 separate from the inner surface of the second level 11112, and the guide blocks 1232 separate from the inner surface of the third level 11113 and the blocks 1113, allowing the base 12 to separate from the fixed base 11.

Figure 11A is a bottom view of the first embodiment of the present invention mounted on a motherboard 100, wherein the base 12 is rotated toward a second horizontal direction relative to the fixing base 11. Figure 11B is a cross-sectional view of Figure 11A. As shown in Figures 11A and 11B, when the base 12 rotates in the second horizontal direction and the blocks 1231 and the guide blocks 1232 are located in the center hole 113, the second slide blocks 124 move along the second slide grooves 114 to a second end 1142 of the second slide grooves 114, respectively. The blocks 1231 abut against the inner surface of the second level 11112, and the guide blocks 1232 are located on the inner side of the third level 11113 but do not contact the third level 11113 and abut against the blocks 1113, so that the base 12 is fixed to the fixed base 11. The first protrusion 11114 serves as a track for the base 12 to rotate relative to the fixing base 11, preventing the base 12 from separating from the fixing base 11 during rotation.

Figure 12A is a schematic diagram of the positioning member 20 of the first embodiment of the present invention rotating in the first horizontal direction. Figure 12B is a schematic diagram of the first slider 122 of the present invention positioned at the first end 2221 of the first slot 222. As shown in Figures 12A and 12B, the head 21 is rotated by the slider 213, causing the head 21 and the rod 22 to rotate in the first horizontal direction. Simultaneously, the semicircular hole 210 at one end of an M.2 solid-state drive 200 aligns with the protrusion 2121. When the head 21 and the rod 22 rotate in the first horizontal direction, the slot 2123 moves away from one end of the M.2 solid state drive 200. The elastic member 23 is compressed to generate an elastic force, and the first slider 122 moves along the first slot 222 to a first end 2221 of the first slot 222.

Figure 13A is a schematic diagram of the first embodiment of the present invention showing the positioning member 20 rotating in the second horizontal direction and securing the M.2 solid-state drive 200. Figure 13B is a schematic diagram of the second slider 124 of the present invention positioned at the second end 2222 of the first slot 222. As shown in Figures 13A and 13B, the elastic force of the elastic member 23 causes the head 21 and rod 22 to rotate in the second horizontal direction, and the first slider 122 moves along the first slot 222 to a second end 2222 of the first slot 222, allowing the locking groove 2123 to secure one end of the M.2 solid-state drive 200 to the motherboard 100.

When the user wants to remove the M.2 SSD 200 from the motherboard 100, they simply rotate the head 21 using the knob 213, causing the head 21 and the lever 22 to rotate in the first horizontal direction. This moves the slot 2123 away from one end of the M.2 SSD 200, allowing the M.2 SSD 200 to be removed from the motherboard 100.

Figure 14 is a perspective view of the second embodiment of the present invention. Figure 15 is an exploded view of the second embodiment of the present invention. Figure 16 is a bottom view of the second embodiment of the present invention mounted on a motherboard 100, wherein the base 12 is rotated relative to the fixing base 11 in a first horizontal direction. As shown in Figures 14, 15, and 16, the elastic fixing device 1A of the second embodiment differs from the elastic fixing device 1 of the first embodiment in that: first, the block and guide block are integrally formed into a rib 1234, which combines the functions of the block and guide block; second, the inner sidewalls of each second chute 114 each have a flange 1143, which is located near the second end 1142 of each second chute 114; and third, when the second chute 124 is located at the second end 1142 of the second chute 114, the rib 1234 is secured to the second end 1142 of the second chute 114. First, the protrusions 1143 can engage the second sliders 124 to prevent them from disengaging from the second ends 1142 of the second slots 114, thereby securing the base 12 to the fixed base 11. Fourth, when the second sliders 124 move along the second slots 114, they push the protrusions 1143 outward to pass through the gaps between the protrusions 1143. After the second sliders 124 pass through the gaps between the protrusions 1143, the protrusions 1143 retract inward and return to their initial positions.
