Description

Technical Field

[0001] The present invention relates to the technical field of solid-state hard disks, and in particular to a solid-state hard disk for a portable computer. Background Art

[0002] Solid-state drives (SSDs) have become the preferred portable storage device due to their low energy consumption, compact size, and fast read / write speeds. As SSDs become more popular and widely used in portable applications, users are increasingly demanding these devices, focusing not only on basic performance but also on ease of use and overall user experience.

[0003] In the existing design of portable solid-state hard drives, two aspects are usually considered: heat dissipation management and data cable storage. In order to ensure that the hard drive can work in the best condition, heat dissipation holes are generally set on the hard drive casing to achieve effective heat dissipation. At the same time, in order to facilitate portability and avoid the loss of data cables, the design of portable solid-state hard drives also includes a space inside the casing specifically for storing data cables. However, the current technology usually designs these two aspects independently, and lacks the design concept of combining heat dissipation management with data cable storage. This separate design makes it difficult to form a complementary effect between heat dissipation technology and data cable storage technology, and the internal space of the hard drive casing cannot be fully utilized, and it is impossible to maximize the advantages of each to improve the overall performance of the product and user experience. In response to the above problems, the present invention proposes a portable computer solid-state hard drive. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a portable computer solid state drive having the following features:

[0017] Beneficial effects:

[0018] 1. The present invention cleverly integrates the heat dissipation structure and storage structure of the solid-state hard drive, ensuring that during use, it is not only convenient for organizing and storing the data cables, but also effectively removes dust and other foreign matter from the heat dissipation holes, avoiding the blockage of the heat dissipation holes that affects the heat dissipation performance of the solid-state hard drive. In addition, the elastic element shared by the heat dissipation structure and the storage structure not only provides the necessary resilience for the data cables to retract into the interior of the housing, but also conducts the heat generated by the electronic components on the circuit board inside the housing in a concentrated manner, thereby providing more efficient heat dissipation for the solid-state hard drive. Furthermore, the overall length of the elastic element in the retracted state is greatly shortened, making room for the storage of the data cables, allowing for more effective utilization of the space inside the housing.

[0019] 2. The present invention divides the interior of the housing into a first space and a second space, each independent of the other, via the data cable. When the sliding member is in the stowed position (i.e., the data cable is retracted into the housing) and the solid-state drive is inactive, the heat dissipation holes communicate only with the second space. Since the second space is disconnected from the first space, this effectively prevents external dust and moisture from entering the first space through the heat dissipation holes, thereby reducing the negative impacts of dust and moisture on key structures such as circuit boards and elastic elements, such as short circuits and poor heat dissipation.

[0020] 3. The sliding component of the present invention includes a frame and a shaft rotatably disposed inside the frame. When the data cable is withdrawn from the housing, rolling contact is achieved between the data cable and the shaft. This helps reduce friction during the relative movement of the sliding component and the data cable, making the data cable easier to withdraw and reducing wear on the data cable by the sliding component.

[0021] 4. The elastic assembly of the present invention is composed of a plurality of sheet-like elastic sheets connected together, with thermally conductive sheets fixedly mounted on at least some of the elastic sheets. The elastic sheets provide excellent elastic properties for the elastic assembly, providing sufficient resilience for the sliding component in the second direction. Furthermore, the thermally conductive sheet ensures good thermal conductivity of the elastic assembly, thereby improving the heat dissipation efficiency of the solid-state drive.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example: See Figures 1 to 7 According to an embodiment of the present invention, a portable computer solid-state drive is provided, comprising a housing 100, a circuit board 600, a sliding member 200, a data cable 300, an elastic element 400, and a locking device 500, wherein the housing 100 has an elongated heat dissipation hole 101 and a wire-passing hole 102 arranged along a first direction; the circuit board 600 is encapsulated in the housing 100; the sliding member 200 is disposed in the housing 100 and has a guide protrusion 201 embedded in the heat dissipation hole 101 and slidable along the length direction of the heat dissipation hole 101; the sliding member 200 has a storage position and a use position arranged along the first direction in the housing 100; a first end of the data cable 300 is connected to the circuit board 60 0 is fixedly connected, and the second end passes around the sliding component 200 and extends out of the wire hole 102; the elastic element 400 is a wavy sheet structure made of heat-conductive material, and is arranged between the sliding component 200 and the housing 100 and can provide the sliding component 200 with a rebound force in a second direction opposite to the first direction, and the elastic element 400 gradually expands and approaches the heat dissipation hole 101 when the sliding component 200 moves in the first direction; the locking device 500 is provided between the sliding component 200 and the housing 100 and is configured to selectively lock the sliding component 200 to the housing 100, so as to restrict or allow the sliding component 200 to slide relative to the housing 100 in the second direction.

[0032] Specifically in this embodiment, the circuit board 600 mainly includes structures such as a main control chip, a flash memory chip, a DRAM cache chip, a power management chip and an interface circuit, among which the main control chip is responsible for operations such as reading, writing and erasing data, and manages the flash memory chip; the flash memory chip is used to store data and is the core storage medium of the solid-state hard disk; the DRAM cache chip is mainly used to cache data to improve data reading and writing speeds; the power management chip ensures that each component can obtain a stable power supply; the interface circuit is responsible for exchanging data with external devices; it can be understood that the data line 300 is equivalent to a flexible extension line, and the first end of the data line 300 is specifically fixedly connected to the interface circuit on the circuit board 600, and the second end of the data line 300 is connected to an external device (such as a laptop) for data exchange, and the second end of the data line 300 can be a Type-C interface 301.

[0033] In a portable computer solid-state drive employing the above-described structure, when the solid-state drive is not activated, the sliding member 200 is in the storage position, the elastic element 400 is in the contracted state, and the majority of the data cable 300 is housed within the housing 100, with only a small portion of its second end remaining exposed from the housing 100. When the solid-state drive needs to be activated, the data cable 300 can be pulled out of the housing 100 via its second end. As the data cable 300 is pulled out, the sliding member 200 moves from the storage position to the use position. When the sliding member 200 reaches the use position, the locking device 500 can be used to secure the position of the sliding member 200. During this process, the sliding member 200, with the aid of the guide protrusion 201, can not only slide stably in the first direction but also clear dust and other obstructions from the heat dissipation holes 101, thereby preventing the heat dissipation holes 101 from becoming clogged and affecting the heat dissipation of the solid-state drive. Secondly, the movement of the sliding member 200 also stretches the elastic element 400 in the first direction and brings it closer to the heat dissipation hole 101. In this way, the elastic element 400 not only provides a rebound force for the sliding member 200 to move in the second direction, but also collects the heat generated by the electronic components on the circuit board 600 in the housing 107 during operation, providing a better heat dissipation effect for the solid-state drive. It can be understood that the principle of heat collection by the elastic member 400 is that because the elastic member 400 is located near the heat dissipation hole 101, the heat of the elastic member 400 itself is more easily transferred through the heat dissipation hole 101 to the outside of the housing 100, where the temperature is lower than that of the elastic member 400. When the heat of the elastic member 400 is transferred to the outside, its own temperature drops. However, the heat in the area near the circuit board 600 inside the housing 100 is relatively high. At this time, the heat near the circuit board 600 is transferred to the elastic member 400, where the temperature is lower, thus forming a heat collection. In addition, since the elastic element 400 provides resilience for the data cable 300 to be retracted into the housing 100 and the overall length of the retracted elastic element 400 is significantly shortened, the necessary space is made available for the storage of the data cable 300, thus making full use of the internal space of the housing 100.

[0034] In this exemplary embodiment, Figure 4As shown, the data cable 300 divides the interior of the housing 100 into a first space 103 and a second space 104, which are mutually independent. The circuit board 600 and the elastic element 400 are both disposed within the first space 103. The heat dissipation holes 101 communicate only with the second space 104 when the sliding member 200 is in the storage position; the heat dissipation holes 101 at least partially communicate with the first space 103 when the sliding member 200 is in the use position. Specifically, in this embodiment, to ensure the independence of the first space 103 and the second space 104, a partition 105 is fixedly installed on the housing 100 near the use position of the sliding member 200. The partition 105, the data cable 300, and the inner wall of the housing 100 together constitute the second space 104. Except for the second space 104, the remaining space within the housing 100 is defined as the first space 103. Besides the circuit board 600 and the elastic element 400, other structures that may be affected by dust and moisture can be placed within the first space 103. The ratio of the first space 103 to the second space 104 adjusts accordingly as the length of the second end of the data cable 300 extending from the housing 100 changes. Specifically, the longer the second end of the data cable 300 extends from the housing 100, the larger the ratio of the first space 103 to the second space 104; conversely, the smaller the ratio. It is noteworthy that although the ratio of the first space 103 to the second space 104 changes with the length of the second end of the data cable 300, the two spaces remain relatively independent. Therefore, when the sliding member 200 is in the stowed position (i.e., the data cable 300 is retracted into the housing 100 and the solid-state drive is inactive), the heat dissipation hole 101 communicates only with the second space 104. Since the second space 104 is not connected to the first space 103, this effectively prevents external dust and moisture from entering the first space 103 through the heat dissipation hole 101, thereby reducing the negative impact of dust and moisture on key structures such as the circuit board 600 and the elastic element 400, such as short circuits and poor heat dissipation.

[0035] In this exemplary embodiment, Figure 6As shown, the locking device 500 includes a clamping head 501, a snap-fit portion 502, and an unlocking member 503. The clamping head 501 is fixedly mounted on the sliding member 200, and the snap-fit portion 502 is fixedly mounted on the housing 100. When the sliding member 200 is in the use position, the clamping head 501 is engaged with the snap-fit portion 502, and the unlocking member 503 can release the engagement between the clamping head 501 and the snap-fit portion 502. Specifically, in this embodiment, as long as the engagement between the clamping head 501 and the snap-fit portion 502 can be achieved and the movement of the sliding member 200 in the second direction can be restricted, the clamping head 501 can be fixed to any position of the sliding member 200 in any suitable manner. Similarly, the snap-fit portion 502 can also be fixed to any position of the housing 100 in any suitable manner. For example, one end of the snap-fit portion 502 can be fixed to the partition 105 fixed to the interior of the housing 100, and the other end can extend toward the sliding member 200. The unlocking component 503 may be in any form as long as it can release the engagement between the clamping head 501 and the fastening portion 502 when necessary.

[0036] In this exemplary embodiment, Figure 6As shown, the clamping head 501 has a first wedge 5010, and the engaging portion 502 is made of an elastic material and has a second wedge 5020 that engages with the first wedge 5010. The engaging portion 502 has a third wedge 5021 corresponding to the unlocking member 503. The unlocking member 503 is slidably connected to the housing 100. The first end of the sliding member 200 is located inside the housing 100, and the second end of the sliding member 200 extends outside the housing 100. The unlocking member 503 is slidably connected to the housing 100. The first end of the sliding member 200 is located inside the housing 100, and the second end of the sliding member 200 extends outside the housing 100. The locking relationship between the clamping head 501 and the engaging portion 502 is released by sliding the unlocking member 503. Specifically, in this embodiment, the clamping head 501 is provided with one first wedge 5010, one on each of the two opposite sides of the clamping head 501. The engaging portion 502 is provided with two second wedges 5020, one on each of the opposing sides of the two engaging portions 502. The inclined surfaces of the second wedges 5020 are inclined in the same direction as the inclined surfaces of the first wedges 5010. Two third wedges 5021 are further disposed on opposite sides of the two locking portions 502. The inclined surfaces of the third wedges 5021 are inclined in the opposite direction to the inclined surfaces of the first wedges 5010. It is understood that when the sliding member 200 moves in the first direction, the inclined surfaces of the first wedges 5010 of the clamping head 501 first contact the inclined surfaces of the second wedges 5020 of the locking portion 502. Then, pushed by the first wedges 5010, the locking portion 502 undergoes elastic deformation until the first wedges 5010 pass over the second wedges 5020, causing the locking portion 502 to rebound. At this point, the first wedges 5010 engage with the second wedges 5020, thereby preventing the sliding member 200 from moving in a second direction opposite to the first direction and locking the sliding member 200 in the use position. If it is necessary to release the locking relationship between the clamping head 501 and the locking part 502, the unlocking component 503 can be pushed to move, and the unlocking component 503 can be used to push the third wedge 5021 to cause the locking part 502 to elastically deform. The deformation of the locking part 502 can release the locking relationship between the first wedge 5010 and the second wedge 5020, thereby releasing the locking relationship between the clamping head 501 and the locking part 502.

[0037] In this exemplary embodiment, Figure 3As shown, the sliding member 200 includes a frame 202 and a shaft 203 rotatably disposed inside the frame 202. The data cable 300 passes through the frame 202 and winds around the shaft 203. The frame 202 has a guide protrusion 201 on its outer side, and the elastic element 400 is disposed between the frame 202 and the housing 100. Specifically, in this embodiment, the frame 202 has a rectangular structure, and the shaft 203 is disposed inside the frame 202. The shaft 203 has protruding ends, forming a cylindrical rotating shaft 2030. The shaft 203 is rotatably connected to the frame 202 via the rotating shafts 2030 at its ends, allowing the shaft 203 to rotate inside the frame 202. The rotation axis of the shaft 203 should be perpendicular to the direction of movement of the sliding member 200 (i.e., the first direction) when the data cable 300 is withdrawn from the housing 100. It can be understood that during the process of pulling the data cable 300 out of the housing 100, rolling contact is achieved between the data cable 300 and the shaft 203, which helps to reduce the friction during the relative movement of the sliding component 200 and the data cable 300, making the data cable 300 easier to pull out and reducing the wear of the sliding component 200 on the data cable 300.

[0038] In this exemplary embodiment, Figure 2 and Figure 3 As shown, the sidewalls of the frame 202 with the guide protrusions 201 are left and right walls 2020. The distance between the left and right walls 2020 is the same as the width of the data cable 300. The inner side of the housing 100 is provided with a wall groove 106 having a depth equal to the thickness of the left and right walls 2020. Specifically, in this embodiment, the thickness of the left and right walls 2020 is half the thickness of the housing 100. The heat dissipation holes 101 are connected to the wall grooves 106. Two wall grooves 106 are provided, one on each opposing inner wall of the housing 100. The left and right walls 2020 of the frame 202 are respectively embedded in the two wall grooves 106. It will be understood that the provision of the wall grooves 106 provides further guidance for the sliding movement of the frame 202. Furthermore, the wall grooves 106 can accommodate the left and right walls 2020 of the frame 202, ensuring that the edges of the data cable 300 are always in contact with the inner wall of the housing 100. This helps to provide a second space 104 that is more independent from the first space 103.

[0039] In this exemplary embodiment, Figure 2 、 Figure 4 and Figure 5As shown, the outer side of the housing 100 is concavely formed with a notch 110. The cable hole 102 is disposed within the notch 110. When the sliding member 200 is in the stowed position, the second end of the data cable 300 is at least partially located within the notch 110. This arrangement provides a space for the second end of the data cable 300, thereby preventing frequent impacts on the end of the data cable 300 during transport of the solid-state drive and thereby extending the service life of the data cable 300. Furthermore, the second end of the unlocking member 503 is also disposed within the notch 110, minimizing the possibility of the sliding member 200 being accidentally unlocked in the in-use position.

[0040] In this exemplary embodiment, Figure 2 As shown, the housing 100 includes a shell 107 and a cover 108. The shell 107 has an opening, and the cover 108 covers the opening of the shell 107, and the two are fixed by screws 109. By using a detachable shell 107 and cover 108 for the housing 100, it is convenient for users to inspect and maintain the components inside the solid-state drive housing 100.

[0041] In this exemplary embodiment, Figure 2 As shown, both the housing 107 and the cover 108 are provided with heat dissipation holes 101, and the sliding member 200 is positioned between the heat dissipation holes 101 of the housing 107 and the heat dissipation holes 101 of the cover 108. Specifically, in this embodiment, both the housing 107 and the cover 108 are provided with five heat dissipation holes 101. Accordingly, the sliding member 200 is also provided with a guide protrusion 201 at a corresponding position of each heat dissipation hole 101. During movement, the sliding member 200 can simultaneously clean these heat dissipation holes 101. It will be understood that when the sliding member 200 moves in a first direction, it causes the elastic element 400 to extend in that direction until the elastic element 400 is positioned between the heat dissipation holes 101 of the housing 107 and the heat dissipation holes 101 of the cover 108. By providing heat dissipation holes 101 at corresponding positions of the shell 107 and the cover 108, external air can be promoted to circulate between the two groups of heat dissipation holes 101, thereby taking away the heat on the elastic element 400 located between the two groups of heat dissipation holes 101, thereby achieving a better heat dissipation effect.

[0042] In this exemplary embodiment, Figure 7As shown, the elastic element 400 is formed by connecting a number of sheet-like springs 401, and a heat conducting sheet 402 is fixedly provided on at least some of the springs 401. The heat conducting sheet 402 is an aluminum sheet or a copper sheet. Specifically, in this embodiment, the elastic sheet is made of spring steel material, and a heat conducting sheet 402 is provided on both sides of each elastic sheet. It can be understood that the elastic sheet gives the elastic element 400 excellent elastic properties, providing sufficient resilience for the sliding component 200 to slide along the second direction. At the same time, the heat conducting sheet 402 ensures that the elastic element 400 has excellent thermal conductivity, thereby improving the heat dissipation efficiency of the solid-state drive.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
