Description

Technical Field

[0001] This invention relates to a portable hard drive, and more particularly to a portable solid-state hard drive using a solid-state drive (SSD). Background Technology

[0002] Existing portable hard drives that commonly use solid-state drives (SSDs) experience a rapid increase in temperature of their internal electronic components when transferring large files at high speeds. Furthermore, since the interior of a portable hard drive is essentially enclosed, the large amount of heat generated by the internal electronic components during operation is difficult to dissipate, which leads to a reduction in the lifespan of the portable hard drive. Summary of the Invention

[0003] This invention discloses a portable solid-state drive (SSD) to improve the situation where, during operation, the large amount of heat generated by the internal electronic components of a known portable SSD cannot be effectively dissipated, which may affect the lifespan of the portable SSD in the long run.

[0004] One embodiment of the present invention discloses a portable solid-state drive, comprising: a fixed housing; a movable housing; an inner housing disposed within the fixed housing and the movable housing, the inner housing including at least one through-hole; a movable mechanism connected to the movable housing; and an internal component disposed within the inner housing, the internal component including: a substrate having a plurality of flash memory chips disposed thereon; a fan; and a switch assembly electrically connected to the fan; wherein, when the portable solid-state drive is powered on and the movable housing is operated, and the movable housing moves away from the fixed housing via the movable mechanism, a portion of the inner housing will be exposed between the fixed housing and the movable housing, and the movable mechanism will actuate the switch assembly to start the fan.

[0005] Preferably, an airflow channel is formed between the fixed housing and the inner housing, and between the movable housing and the inner housing, and the airflow channel is connected to the perforation of the inner housing; when a part of the inner housing is exposed between the fixed housing and the movable housing, the airflow channel is connected to the outside; when the fan is started, the air located between the inner housing and the substrate can flow to the outside of the portable solid-state drive through the perforation and the airflow channel.

[0006] Preferably, a gap is formed between the fixed housing and the inner housing, which constitutes part of the airflow channel. Multiple grooves are formed on the outer side of the inner housing, which constitute part of the airflow channel. A gap is formed between the movable housing and the inner housing, which constitutes part of the airflow channel.

[0007] Preferably, the movable housing is operable to switch between an open state and a closed state via a movable mechanism; when the movable housing is in the open state, a portion of the inner housing is exposed between the fixed housing and the movable housing, and the fan is turned on; when the movable housing is in the closed state, the portion of the inner housing exposed in the open state is covered by the movable housing, and the movable mechanism actuates the switching assembly to turn off the fan; when the movable housing is in the open state, at least one engaging structure of the inner housing and at least one engaging structure of the movable housing engage with each other, thereby restricting the movable housing from moving away from the inner housing.

[0008] Preferably, the switch assembly is a limit switch, which has a spring arm and is electrically connected to the fan via a substrate. The body has a protrusion. When the movable mechanism is in the open state, the protrusion of the body will press against the spring arm, and the internal circuit of the limit switch will switch to the conducting state. When the movable mechanism is in the closed state, the protrusion of the body will not press against the spring arm, and the internal circuit of the limit switch will switch to the closed state.

[0009] Preferably, the movable mechanism includes a body, two pop-out springs, and a limiting member. The body is connected to the movable housing and is located inside the movable housing. One end of each pop-out spring is fixed to the inner housing, and the other end of each pop-out spring is connected to the body. When the movable housing is in the closed state, the two pop-out springs are compressed, and the limiting member engages with a part of a guide structure of the inner housing. When the movable housing is in the open state, the limiting member is not engaged with the part of the guide structure, and the movable housing will move away from the fixed housing due to the elastic restoring force generated by the compression of the two pop-out springs.

[0010] Preferably, when the movable housing is in the closed state and is pressed to move toward the fixed housing, the limiting member will move relative to the guide structure and will no longer engage with the guide structure. The movable housing can then move away from the fixed housing due to the elastic restoring force provided by the two pop-out springs.

[0011] Preferably, one end of the limiting member is pivotally connected to the body, and the limiting member can be driven by the guiding structure to swing relative to the body. A limiting groove is formed in the indentation of a top surface of the body, and the limiting member is located in the limiting groove. The limiting groove is used to limit the swing range of the limiting member relative to the body.

[0012] Preferably, the other end of the limiting member is bent away from the top surface to form a limiting part, which is used to connect with the guide structure of the inner shell; when the moving mechanism moves relative to the inner shell, the limiting part will be driven by the guide structure, and the limiting member will swing to the left or right relative to the body.

[0013] Preferably, the guide structure is a groove, which includes a limiting section, an exit guide section, a straight section, and an entry guide section. The limiting section, the exit guide section, and the entry guide section together form an annular section. The limiting section is U-shaped. One end of the exit guide section is connected to one end of the limiting section, and one end of the entry guide section is connected to the other end of the limiting section. The other ends of both the exit guide section and the entry guide section are connected to one end of the straight section. When the movable housing is in the closed state, the limiting part engages with the limiting section. In the section; when the limiting part is engaged in the limiting section and the movable housing is compressed, the limiting part will move along the limiting section to the exit guide section, and the limiting member will no longer be engaged in the limiting section. The movable housing can then be moved away from the fixed housing by the elastic restoring force generated by the two pop-out springs. The limiting part will then move from the exit guide section to the straight section; when the movable housing is in the closed state and the movable housing is compressed, the limiting part will move sequentially along the straight section to the entry guide section, and then move along the entry guide section to the limiting section.

[0014] Preferably, the connection between the limiting section and the moving-in guide section is U-shaped, and the connection between the limiting section and the moving-out guide section is U-shaped.

[0015] In summary, the portable solid-state drive of the present invention, through the design of a fixed housing, an inner housing, a movable mechanism, a switch assembly, and a fan, allows users to easily press the movable housing to expose a portion of the inner housing while using the portable solid-state drive, and simultaneously activate the fan inside the portable solid-state drive. This effectively dissipates heat from the portable solid-state drive.

[0027] In the following description, if a specific drawing is indicated or shown in a particular drawing, it is only to emphasize that most of the relevant content mentioned in the following description appears in that particular drawing, but does not limit the following description to refer only to that particular drawing.

[0028] Please refer to the following: Figures 1 to 5 , Figures 1 to 3 These are schematic diagrams showing the portable solid-state drive of the present invention in different states. Figure 4 and Figure 5 These are partially exploded views of the portable solid-state drive 100 of the present invention. The portable solid-state drive 100 of the present invention includes a fixed housing 1, a movable housing 2, an inner housing 3, a movable mechanism 4, and an internal component 5. The inner housing 3 is disposed within the fixed housing 1 and the movable housing 2. The inner housing 3 includes at least one through-hole 31 that penetrates the inner housing 3. The movable mechanism 4 is connected to the movable housing 2. In practical applications, the fixed housing 1 and the movable housing 2 can be made of metal, for example, thereby improving the heat dissipation effect of the portable solid-state drive 100 during operation.

[0029] like Figure 5 As shown in the accompanying drawings of this embodiment, the movable housing 2 includes a hollow structure 21 and an end cap 22 as an example. However, the number, shape and connection relationship of the components included in the movable housing 2 are not limited to those shown in the drawings.

[0030] Internal component 5 is disposed within inner housing 3. Internal component 5 includes: a base plate 51, a fan 52, and a switch assembly 53 (e.g., ...). Figure 16 (As shown). The substrate 51 can be various circuit boards depending on the requirements. The substrate 51 is provided with multiple flash memory chips 54. A fan 52 is disposed on the substrate 51. A switch assembly 53 (such as...) Figure 16 As shown) is disposed on substrate 51, and switch assembly 53 (as shown) Figure 16 (As shown) Electrically connected to fan 52. The base plate 51 is also provided with a connection slot 55, which is exposed outside the fixed housing 1.

[0031] When the movable housing 2 is operated, and the movable housing 2 moves away from the fixed housing 1 via the movable mechanism 4, a part of the inner housing 3 will be exposed between the fixed housing 1 and the movable housing 2, and the movable mechanism 4 will drive the switch assembly 53 to operate, thereby starting the fan 52.

[0032] In a preferred embodiment, at least one airflow channel may be formed between the fixed housing 1 and the inner housing 3, and between the movable housing 2 and the inner housing 3, and the airflow channel is connected to the perforation 31 of the inner housing 3. When a portion of the inner housing 3 is exposed between the fixed housing 1 and the movable housing 2, the airflow channel will be connected to the outside. Thus, when the fan 52 is activated, the air located between the inner housing 3 and the substrate 51 can flow to the outside of the portable solid-state drive 100 through the perforation 31 and the airflow channel, thereby further improving the heat dissipation effect of the portable solid-state drive 100.

[0033] Specifically, there may be a gap between the inner shell 3 and the fixed shell 1, which forms part of the airflow channel. There may also be a gap between the inner shell 3 and the movable shell 2, which forms part of the airflow channel. Preferably, the outer side of the inner shell 3 may also have a plurality of recesses 32 formed inward. The plurality of recesses 32 can form part of the airflow channel together with the inner sidewall of the fixed shell 1, and the plurality of recesses 32 can also form part of the airflow channel together with the inner sidewall of the movable shell 2.

[0034] like Figures 1 to 3 As shown, when a user wishes to use the portable solid-state drive 100 of the present invention (e.g. Figure 1 When (as shown), the user can first plug the connecting cable into the connecting slot 55 to allow external electronic devices to provide power to the portable solid-state drive 100 through the connecting cable. Then, the user can press the movable housing 2 to move the movable housing 2 towards the fixed housing 1 until the end of the movable housing 2 near the fixed housing 1 abuts against the end of the fixed housing 1 (as shown). Figure 2 (As shown), then the user can release the pressure on the movable housing 2. At this time, the movable mechanism 4 (as shown) Figure 5 (As shown) This will cause the movable housing 2 to move away from the fixed housing 1, thus causing the movable housing 2 to move from... Figure 2 The state shown is transformed into Figure 3 The state shown, and the active mechanism 4 (such as Figure 5 (As shown) will simultaneously drive the switching assembly 53 (such as...) Figure 16 As shown, the fan 52 is turned on.

[0035] The portable solid-state drive 100 is in a closed state (e.g.) Figure 1 (as shown), converted to Figure 3 When in the open state as shown, a portion of the inner casing 3, which was originally covered by the movable casing 2, will be exposed between the movable casing 2 and the fixed casing 1; conversely, when the portable solid-state drive 100 is in the open state, a portion of the inner casing 3 will be exposed between the movable casing 2 and the fixed casing 1. Figure 3 The shown on state is changed to Figure 1 When in the closed state shown, a portion of the inner shell 3, which was originally exposed between the fixed shell 1 and the movable shell 2, will move into the movable shell 2 and be covered by the movable shell 2.

[0036] To go further, such as Figures 5 to 8 As shown, the movable mechanism 4 includes a body 41, two pop-out springs 42, and a limiting member 43. One end of the body 41 is detachably connected to the end cap 22 of the movable housing 2. The body 41 has two guide rods 411 opposite to the end connected to the end cap 22. The two pop-out springs 42 are sleeved on the two guide rods 411, and one end of each pop-out spring 42 is fixed to the body 41.

[0037] One end of the limiting member 43 is pivotally connected to a top surface 412 of the body 41, and the limiting member 43 can be driven to swing left or right on the top surface 412. The end of the limiting member 43 is bent away from the top surface 412 to form a limiting portion 431, which is used to connect with a guide structure 35 on the inner side of the inner housing 3 (e.g., Figure 8 (as shown) are connected.

[0038] When the movable mechanism 4 moves relative to the inner housing 3, the limiting part 431 will be driven by the guide structure 35, and the limiting member 43 will swing left or right relative to the body 41. In practical applications, the top surface 412 of the body 41 may be recessed to form a limiting groove 413, and the limiting member 43 is correspondingly located in the limiting groove 413. The limiting groove 413 is used to limit the swing range of the limiting member 43 relative to the body 41; the limiting groove 413 may be approximately fan-shaped, for example, but is not limited to this.

[0039] like Figures 8 to 10 As shown, the inner shell 3 has two spring fixing structures 33 on its inner side, each spring fixing structure 33 having a through hole 331. When the movable mechanism 4 is installed at one end of the inner shell 3, a portion of the two guide rods 411 of the movable mechanism 4 will pass through the two through holes 331 of the two spring fixing structures 33 of the inner shell 3, while the other end of each pop-out spring 42 will be fixed to one of the spring fixing structures 33.

[0040] like Figure 1 and Figure 10 As shown, when the portable solid-state drive 100 is in the closed state (i.e., when the movable mechanism 4 is in the closed state), the two pop-out springs 42 are in a compressed state, and at this time the limiting member 43 of the movable mechanism 4 (such as...) Figure 7 (as shown) and the guiding structure 35 of the inner shell 3 (as shown) Figure 8 The two parts are interlocked (as shown below), and the moving mechanism 4 cannot move away from the fixed housing 1.

[0041] Following on, such as Figure 2 , Figure 3 and Figure 11 As shown, the user is Figure 1 In the current state, pressing the movable housing 2 causes it to move towards the fixed housing 1, and the limiting member 43 of the movable mechanism 4 (such as...) Figure 7 (as shown) and the guiding structure 35 of the inner shell 3 (as shown) Figure 8 The two springs (as shown) will no longer be interlocked (details to follow), and the elastic restoring force generated by the compression of the two springs 42 will act on the movable mechanism 4, thereby causing the movable mechanism 4 to move away from the fixed housing 1. Figure 2 The portable solid-state drive 100 shown will be converted to Figure 3 The state shown is the on state.

[0042] like Figures 6 to 9 As shown, the body 41 also includes three engaging structures. Each engaging structure can be a rectangular groove formed by the indentation of the body 41. Two engaging structures are defined as a first engaging structure 414, and the other engaging structure is defined as a second engaging structure 415. The two first engaging structures 414 can be disposed adjacent to the limiting groove 413, and the second engaging structure 415 can be disposed adjacent to one of the guide rods 411. The length of the two first engaging structures 414 is less than the length of the second engaging structure 415. The inner side of the inner housing 3 can have three engaging structures 34, which are used to engage with the two first engaging structures 414 and the second engaging structure 415 of the body 41 of the movable mechanism 4.

[0043] like Figure 6 , Figure 7 and Figure 10 As shown, when the portable solid-state drive 100 is in the open state (i.e., when the movable mechanism 4 is in the open state), the three engaging structures 34 of the inner shell 3 will engage with the two first engaging structures 414 and the second engaging structure 415 of the movable mechanism 4, and the movable mechanism 4 will no longer be able to move relative to the inner shell 3. In other words, the movable shell 2 will no longer be able to move away from the inner shell 3.

[0044] In other words, when the user presses Figure 1 The movable casing 2 of the portable solid-state drive 100, so that the portable solid-state drive 100 is made of Figure 1 Convert to Figure 2 Then, when the user releases their hand and no longer presses the movable housing 2, the two pop-out springs 42 (such as...) Figure 10 As shown, the elastic restoring force generated by the pressure will drive the movable housing 2 to move away from the fixed housing 1 until the three engaging structures 34 of the inner housing 3 engage with the two first engaging structures 414 and the second engaging structures 415 of the movable mechanism 4.

[0045] Of course, the number, location, and specific form of the engaging structures included in the moving mechanism 4, and the number, location, and specific form of the engaging structures 34 included in the inner shell 3, can be varied according to requirements, as long as they can cooperate with each other to limit the range of movement between the moving mechanism 4 and the inner shell 3. The figure shown is only one example.

[0046] In contrast, the user sees the portable SSD 100 as enabled (e.g., ...). Figure 3 and Figure 10 As shown, the user can press the movable housing 2 to move it closer to the fixed housing 1 until the movable housing 2 touches one end of the fixed housing 1. Then, the user can release the pressure, and the portable solid-state drive 100 will be displaced. Figure 2 The displayed state will automatically change to Figure 1 The state shown (details to follow), and during this process, the limiting member 43 of the moving mechanism 4 (such as...) Figure 7 As shown), the guide structure 35 of the inner shell 3 (as shown) will be connected to the inner shell 3. Figure 8 (As shown) they engage again, and after the moving mechanism 4 moves toward the inner housing 3, the moving mechanism 4 will activate the switch assembly 53, causing the switch assembly 53 to change from the open state to the closed state, thereby stopping the fan 52 from running.

[0047] like Figures 1 to 3 As shown, simply put, when the user plugs the portable SSD 100 into the connection cable and powers on the portable SSD 100, the user can press the movable casing 2 to move the portable SSD 100 from its original position. Figure 1 State transition to Figure 3 Status, when the external solid-state drive 100 is switched to Figure 3 When the power is on, fan 52 will start automatically; otherwise, the user will press... Figure 3 The movable housing 2 of the portable solid-state drive 100 shown is used to make the portable solid-state drive 100 consist of... Figure 3 State, transition to Figure 1 When in this state, fan 52 will automatically turn off.

[0048] like Figure 9 and Figure 12 As shown, the guide structure 35 of the inner shell 3 can be a groove, which includes a limiting section 351, an exit guide section 352, a straight section 353, and an entry guide section 354. The limiting section 351, the exit guide section 352, and the entry guide section 354 together form an annular section. The limiting section 351 is U-shaped. One end of the exit guide section 352 is connected to one end of the limiting section 351, and one end of the entry guide section 354 is connected to the other end of the limiting section 351. The other ends of the exit guide section 352 and the other ends of the entry guide section 354 are both connected to one end of the straight section 353.

[0049] like Figure 1 , Figure 7 , Figure 9 , Figure 10 and Figure 12 As shown, when the portable solid-state drive 100 is in the closed state (i.e., when the movable mechanism 4 is in the closed state), the limiting part 431 of the limiting member 43 will be located at the lowest position of the limiting section 351 of the guide structure 35 of the inner housing 3. At this time, the two pop-out springs 42 are compressed, and the limiting part 431 and the limiting section 351 of the guide structure 35 are mutually engaged, and the movable mechanism 4 will not be able to move away from the fixed housing 1. In other words, when the portable solid-state drive 100 is in the closed state... Figure 1 When in the closed state shown, the limiting member 43 and the guide structure 35 are in an engaged state, and the moving mechanism 4 will not be able to move away from the fixed housing 1.

[0050] Following on, when the user presses... Figure 1 The movable housing 2 of the portable solid-state drive 100 shown is used to convert the portable solid-state drive 100 into a portable solid-state drive 100. Figure 2 In the indicated state, the limiting member 43 and the guide structure 35 will change from an engaged state to an unlocked state, and the movable mechanism 4 will be able to move away from the fixed housing 1. More specifically, as shown... Figure 2 , Figure 7 , Figure 10 and Figure 13 As shown, after the user presses the movable housing 2, the movable mechanism 4 will move towards the fixed housing 1, and the limiting member 43 will move towards the fixed housing 1 along with the movable mechanism 4. The limiting part 431 will move along the limiting section 351 and from the limiting section 351 to the exit guide section 352.

[0051] Following on, such as Figure 3 , Figure 7 , Figure 13 and Figure 14As shown, when the limiting part 431 leaves the limiting section 351 and moves to the exit guide section 352, the limiting member 43 and the guide structure 35 will no longer be in the engaged state, the movable mechanism 4 will no longer be restricted, and the two pop-out springs 42 will no longer be compressed. The elastic restoring force generated by the previous compression of the two pop-out springs 42 will drive the movable mechanism 4 to move away from the fixed housing 1 until the two first engaging structures 414 of the movable mechanism 4 and the first engaging structure 414 respectively engage with the three engaging structures 34 of the inner housing 3 (e.g., Figure 6 , Figure 8 and Figure 11 As shown, during the movement of the moving mechanism 4 relative to the inner housing 3, the limiting part 431 will move along the removal guide section 352 to the straight section 353.

[0052] like Figure 3 and Figure 14 As shown, when the portable solid-state drive 100 is in the open state (i.e., when the movable mechanism 4 is in the open state), the limiting part 431 is the straight section 353 of the guide structure 35 of the inner housing 3. At this time, the user can press the movable housing 2 to move the movable housing 2 towards the fixed housing 1. Figure 2 , Figure 3 , Figure 14 and Figure 15 As shown, when the user presses Figure 3 When the movable housing 2 of the portable solid-state drive 100 is in use, the limiting part 431 will move sequentially along the straight section 353 and the moving guide section 354; when Figure 3 When one end of the movable housing 2 is pressed by the user and abuts against one end of the fixed housing 1 (i.e., the portable solid-state drive 100 is...), Figure 3 Convert to Figure 2 When the limit section 431 moves to the position where the guide section 354 and the limit section 351 meet, the limit section 431 will move.

[0053] like Figure 2 and Figure 15 As shown, when one end of the movable housing 2 abuts against the fixed housing 1, and the limiting part 431 moves to the position where the guide section 354 and the limiting section 351 meet, the user can stop pressing the movable housing 2. At this time, the two pop-out springs 42 will drive the movable mechanism 4 to move away from the fixed housing 1, and the limiting part 431 will enter the limiting groove 413. When the limiting part 431 enters the lowest position in the limiting section 351, the limiting part 431 will engage with the limiting section 351, and the movable mechanism 4 will no longer be able to move away from the fixed housing 1. Accordingly, the limiting member 43 and the guide structure 35 will change from the unlocked state to the engaged state, and the portable solid-state drive 100 will change from... Figure 2 The state shown is transformed into Figure 1 The state shown (i.e., the active mechanism 4 changes from the open state to the closed state).

[0054] In a preferred embodiment, the connection between the limiting section 351 and the insertion guide section 354 can be U-shaped, and the connection between the limiting section 351 and the exit guide section 352 can also be U-shaped. This allows the user to press... Figure 1 The movable housing 2 shown allows the portable solid-state drive 100 to be mounted on a single unit. Figure 1 Convert to Figure 2 When the user is in this state, they will feel the limiting part 431 move away from the limiting section 351 and enter the removal guide section 352, and the user will know it's time to release. Conversely, when the user presses... Figure 3 The movable housing 2 shown allows the portable solid-state drive 100 to be mounted on a single unit. Figure 13 Convert to Figure 2 When the user is in the correct state, they will feel the limiting part 431 move away from the guide section 354 and enter the limiting section 351. At this time, the user will know to let go.

[0055] Please see Figure 16 This is a partial side view of the movable mechanism and switch assembly when the portable solid-state drive of the present invention is in the open state. In practical applications, the switch assembly 53 is a limit switch with a spring arm 531. The limit switch is electrically connected to the fan 52 through the substrate 51, and the body 41 has a protrusion 416. When the movable mechanism 4 is in the open state, the protrusion 416 of the body 41 will press against the spring arm 531, and the internal circuit of the limit switch will switch to the conducting state, so that the fan 52 will receive power and start. Conversely, when the movable mechanism 4 is in the closed state, the protrusion 416 of the body 41 will no longer press against the spring arm 531, and the internal circuit of the limit switch will switch from the conducting state to the non-conducting state, so that the fan 52 will lose power and turn off.

[0056] It should be noted that when the portable solid-state drive is in an open or closed state as indicated in the above embodiments, it is equivalent to the movable housing being in an open or closed state.

[0057] In summary, the portable solid-state drive of the present invention, through the design of a fixed shell, a movable shell, an inner shell, a movable mechanism, and a fan, allows the user to simply press the movable shell to expose the part of the inner shell that was originally covered by the movable shell, and at the same time turn on the fan, so that the large amount of heat generated by the portable solid-state drive during operation can be dissipated to the outside.

[0058] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made based on the description and drawings of the present invention are included within the protection scope of the present invention.
