Description

Technical Field

[0001] The utility model relates to the technical field of hard disks, and in particular to a mobile solid-state hard disk capable of dissipating heat according to usage status. Background Art

[0002] With the development of information technology, the demand for mobile storage devices is growing. Mobile solid-state drives have become an ideal choice for modern people to store data due to their fast data reading and writing capabilities, low energy consumption and lightweight design. Unlike traditional mechanical hard drives, mobile solid-state drives mainly rely on semiconductor memory for data storage, which not only improves data processing efficiency, but also enhances the durability and security of the device.

[0003] However, in actual applications, heat dissipation has become a key factor affecting user experience. Since mobile solid-state drives generate a certain amount of heat during high-intensity data reading and writing, in order to ensure their normal operation and extend their service life, it is usually necessary to design a heat dissipation mechanism to maintain a reasonable temperature range.

[0004] For example, the Chinese utility model "A mobile hard disk protection structure and a mobile hard disk" with announcement number CN217588426 includes a shell and a shell cap, a hard disk body is provided inside the shell, a plurality of lower pads are provided on the bottom inner wall of the shell, a plurality of side gaskets are fixedly connected to the inner walls on both sides of the shell, a plurality of clamping pads are fixedly connected to the front inner wall and the back inner wall of the shell, slots are provided on the inner walls on both sides of the top of the shell, a plurality of plug-in plates matching the slots are provided on the bottom outer wall of the shell cap, screw grooves are provided on the outer walls on both sides of the top of the shell, bolts are connected to the internal threads of the screw grooves, a plurality of upper pads are provided on the top inner wall of the shell cap, and a plurality of clamping pads are fixedly connected to the front inner wall and the back inner wall of the shell cap.

[0005] In the above patent, although the heat dissipation holes are used to facilitate heat dissipation of the mobile hard disk during operation, thereby preventing the internal temperature of the shell from being too high and causing the mobile hard disk to malfunction, and a dustproof net is added to intercept dust to prevent dust from entering the shell through the heat dissipation holes, causing dust accumulation inside the shell, when the hard disk is not in use, the heat dissipation holes are in a normally open state, and the dustproof net is exposed to the external environment for a long time, which causes a large amount of dust and fine particles to accumulate quickly on the dustproof net. The accumulation of dust will cause air circulation to be obstructed, affecting and reducing the heat dissipation efficiency. At the same time, although the dustproof net can prevent dust and fine particles from entering the hard disk, it cannot intercept water stains, causing water stains to enter the hard disk through the heat dissipation holes in the normally open state, thereby affecting its normal working performance and possibly shortening the service life of the product.

[0006] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0007] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a mobile solid-state hard drive capable of dissipating heat according to the state of use, comprising a housing, a circuit board within the housing, and a plug interface at one end of the circuit board, the housing being provided with a notch corresponding to the plug interface, the plug interface being exposed to the housing through the notch;

[0009] The shell has an upper end opening, a side end of the shell is provided with a heat dissipation hole, the upper end of the shell is covered with a cover plate, the lower end of the cover plate is provided with a cover frame, the cover frame is located inside the shell and fits with the inner wall of the shell, and the cover frame has a through opening that is staggered with the heat dissipation hole;

[0010] The four corners of the shell are provided with a sleeve, an electromagnet is installed at the top of the sleeve, a movable long slot is opened on the sleeve, a movable block is provided inside the sleeve, an iron block is embedded in the movable block facing the electromagnet, a contraction spring is provided between the movable block and the shell, a kit corresponding to the sleeve is provided at the four corners of the lower end of the cover plate, and a sleeve corresponding to the movable long slot is provided on the four sides of the lower end of the kit. The four sleeves are wrapped and sleeved on the outside of the sleeve, and a connecting part is provided at the position of the movable block corresponding to the movable long slot, and the connecting part passes through the movable long slot and is connected to the sleeve plate;

[0011] Wherein, the electromagnet is electrically connected to the circuit board.

[0012] As a further solution of the present invention: the cover frame has two through openings, the two through openings are located near the top and near the bottom, and there is a covering area corresponding to the position of the heat dissipation hole between the two through openings.

[0013] As a further solution of the present invention: a dustproof net is provided in the through opening.

[0014] As a further solution of the present invention: a fixing block is provided on the outside of the sleeve plate, the fixing block has a positioning through hole, and an orientation rod corresponding to the positioning through hole is provided on the inner bottom surface of the shell, and the orientation rod passes through the positioning through hole.

[0015] As a further solution of the present invention: a temperature control chip is further provided on the circuit board, and the temperature control chip is electrically connected to the electromagnet.

[0016] As a further solution of the present invention: an annular sealing groove is provided on the edge of the upper end of the shell, and a sealing ring is provided at the lower end of the cover plate to match the sealing groove.

[0017] As a further solution of the present invention: the edge of the cover plate has an edge, and the edge is arranged outside the shell.

[0018] As a further solution of the present invention: a clearance opening is provided at a position corresponding to the insertion interface at the lower end of the covering frame.

[0019] Compared with the prior art, the beneficial effects of the present technical solution are as follows: when the hard disk is in use, the plug interface is connected to the transmission device, so that the electromagnet is energized to generate a magnetic field to generate suction, the movable block and the iron block move toward the electromagnet and are adsorbed and fixed, the movable block sleeve and the kit push the cover plate and the cover frame to move upward, and the upward movement of the cover frame makes the opening correspond to the position of the heat dissipation hole, thereby facilitating the heat dissipation of the hard disk in the working state through the heat dissipation hole, thereby preventing the hard disk from being damaged due to excessive temperature and unable to work normally. After the hard disk is used up and the device is disconnected from the hard disk, the electromagnet loses its magnetic attraction to the iron block due to power failure, and the contraction spring is used to shrink and restore due to its own contractility, so that the cover plate and the cover frame move down and reset, so that the top of the shell is covered by the cover plate again, and the heat dissipation hole is covered by the cover frame again, so as to prevent impurities such as dust and water stains from entering the hard disk through the heat dissipation hole when the hard disk is not in use, thereby affecting the normal working performance of the hard disk;

[0020] After the cover plate and the cover frame move upward, the opening closer to the lower end of the two openings is located at the position of the heat dissipation hole, while the opening closer to the upper end moves upward with the cover plate and is located in the gap between the cover plate and the housing. This allows the heat inside the hard drive to dissipate through the gap between the cover plate and the housing, thereby improving the heat dissipation effect of the hard drive. In addition, the dust screens installed in the two openings can also prevent dust from entering the housing through the openings and affecting the use of the hard drive.

[0021] At the same time, during use, the temperature inside the hard disk can be measured through the temperature control chip and a threshold can be set. When the temperature reaches the threshold, the electromagnet is powered on and the cover and shield are moved up to facilitate the heat dissipation of the hard disk. Then, using the temperature control chip, when the temperature inside the hard disk is low, the cover and shield can remain in place, thereby reducing the waste of electricity and energy.

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] See also Figure 1-4 A mobile solid-state hard drive that can dissipate heat according to the usage status includes a housing 1, a circuit board 2 in the housing 1, and a plug interface 21 at one end of the circuit board 2. The housing 1 is provided with a notch corresponding to the plug interface 21. The plug interface 21 is exposed to the housing 1 through the notch. A main control chip, a cache chip, and a flash memory chip are provided on the circuit board 2.

[0032] Preferably, the housing 1 has an upper end open, a side end of the housing 1 is provided with a heat dissipation hole 11, the upper end of the housing 1 is covered with a cover plate 3, a lower end of the cover plate 3 is provided with a covering frame 31, the covering frame 31 is located inside the housing 1 and is in contact with the inner wall of the housing 1, and the covering frame 31 has a through opening 32 that is staggered with the heat dissipation hole 11;

[0033] A sleeve 4 is provided at the four corners of the shell 1, an electromagnet 41 is installed at the top of the sleeve, a movable long slot 42 is opened on the sleeve 4, a movable block 5 is provided inside the sleeve 4, and an iron block 51 is embedded in the movable block 5 facing the electromagnet 41. A contraction spring 6 is provided between the movable block 5 and the shell 1, and a sleeve 52 corresponding to the sleeve 4 is provided at the four corners of the lower end of the cover plate 3. The four sides of the lower end of the sleeve 52 have sleeve plates 53 corresponding to the movable long slot 42. The four sleeve plates 53 wrap and sleeve the outside of the sleeve 4. A connecting portion 54 is provided at the position corresponding to the movable long slot 42, and the connecting portion 54 passes through the movable long slot 42 and is connected to the sleeve plate 53;

[0034] The electromagnet 41 is electrically connected to the circuit board 2 .

[0035] Specifically, when the hard disk is not in use, the cover plate 3 covers the upper opening of the housing 1, and the cover frame 31 seals the heat dissipation holes 11 of the housing 1, thereby preventing impurities such as dust and water stains from entering the interior of the hard disk.

[0036] When the hard disk is in use, the plug interface 21 is connected to the transmission device, so that the electromagnet 41 located at the top of the four sleeves 4 and electrically connected to the circuit board 2 is energized. After the electromagnet 41 is energized, a magnetic field is generated, which generates suction to the iron block 51 on the movable block 5, so that the movable block 5 and the iron block 51 move toward the electromagnet 41 and are adsorbed and fixed by the electromagnet 41. At the same time, the movable block 5 pulls the contraction spring 6 at the bottom, and the movable block 5 passes through the movable long slot 42 through the connecting portion 54 to drive the four sleeves 53 outside the sleeve 4, and the kit 52 on the sleeve 53, thereby pushing the cover plate 3 and the cover frame 31 to move upward. As the cover frame 31 moves upward, the through-hole 32 which is offset from the heat dissipation hole 11 gradually moves to the position corresponding to the heat dissipation hole 11. , so that the heat dissipation hole 11 is connected with the inside of the shell 1, and then the heat dissipation hole 11 is used to facilitate the hard disk to dissipate heat in the working state, avoiding the hard disk being damaged due to excessive temperature and unable to work normally. After the hard disk is used up and the device is disconnected from the hard disk, the electromagnet 41 loses its magnetic attraction to the iron block 51 due to power failure. At this time, the pulled-open contraction spring 6 contracts and recovers due to its own contractility, thereby driving the movable block 5, and the movable block 5 drives the cover plate 3 and the cover frame 31 to move down and reset, so that the top of the shell 1 is covered by the cover plate 3 again, and the heat dissipation hole 11 is covered by the cover frame 31 again, so as to avoid impurities such as dust and water stains entering the inside of the hard disk through the heat dissipation hole 11 when the hard disk is not in use, affecting the normal working performance of the hard disk.

[0037] Preferably, the cover frame 31 has two openings 32, which are located near the top and the bottom, and a covering area 33 corresponding to the position of the heat dissipation hole 11 is provided between the two openings 32;

[0038] A dustproof net 7 is provided in the opening 32 .

[0039] Specifically, after the cover plate 3 and the cover frame 31 move upward, the opening 32 closer to the lower end of the two openings 32 is located at the position of the heat dissipation hole 11, while the opening 32 closer to the upper end moves upward with the cover plate 3 and is located in the gap between the cover plate 3 and the housing 1 after the cover plate 3 moves upward. As a result, the heat inside the hard disk can be dissipated through the gap between the cover plate 3 and the housing 1, thereby improving the heat dissipation effect of the hard disk. In addition, the dustproof nets 7 provided in the two openings 32 can also prevent dust from entering the interior of the housing 1 through the openings 32 and affecting the use of the hard disk.

[0040] After the cover plate 3 and the covering frame 31 are moved downward and reset, the covering area 33 between the two openings 32 covers the heat dissipation hole 11 .

[0041] Preferably, a clearance opening 34 is provided at the lower end of the cover frame 31 at a position corresponding to the plug-in port 21 . The clearance opening 34 prevents the plug-in port 21 from affecting the vertical displacement of the cover frame 31 .

[0042] Preferably, a fixing block 55 is provided on the outside of the sleeve plate 53 , and the fixing block 55 has a positioning through hole 56 . An orientation rod 8 corresponding to the positioning through hole 56 is provided on the inner bottom surface of the shell 1 , and the orientation rod 8 passes through the positioning through hole 56 .

[0043] Specifically, when the movable block 5, the sleeve plate 53 and the sleeve 52 push the cover plate 3 and the cover plate 31 to move upward, the sliding connection between the positioning through hole 56 of the fixed block 55 and the directional rod 8 can ensure the stability of the movement of the cover plate 3 and the cover plate 31 and avoid excessive wear caused by shaking.

[0044] Furthermore, a temperature control chip 9 is provided on the circuit board 2 , and the temperature control chip 9 is electrically connected to the electromagnet 41 .

[0045] Specifically, during use, the temperature inside the hard disk can be measured by the temperature control chip 9 and a threshold value can be set. When the temperature reaches the threshold value, the electromagnet 41 is powered on and the cover plate 3 and the shielding plate 31 are moved upward to facilitate heat dissipation of the hard disk. Furthermore, by utilizing the temperature control chip 9, when the temperature inside the hard disk is low, the cover plate 3 and the shielding plate 31 can remain in place, thereby reducing waste of electric energy.

[0046] For example, when using a hard disk to transfer smaller files, the usage time is usually not too long, so there is no risk of the hard disk temperature being too high. The temperature control chip 9 can be set to prevent the electromagnet 41 from being powered on, thereby saving energy.

[0047] Furthermore, an annular sealing groove 12 is provided at the upper edge of the shell 1 , and a sealing ring 10 that matches the sealing groove 12 is provided at the lower end of the cover plate 3 .

[0048] Specifically, when the cover plate 3 is placed on the housing 1, the sealing groove 12 and the sealing ring 10 can enhance the sealing between the cover plate 3 and the housing 1, thereby preventing water from entering the interior through the gap between the cover plate 3 and the housing 1;

[0049] When the cover plate 3 is moved up and then down to reset, since the power provided by the contraction spring 6 is limited, the user can press the cover plate 3 to make the sealing ring 10 fit tightly with the sealing groove 12.

[0050] Furthermore, the edge of the cover plate 3 has an edge 35, and the edge 35 is arranged outside the shell 1. The design of the edge 35 can prevent water droplets and other water bodies from directly contacting the contact surface between the cover plate 3 and the shell 1, thereby further improving the waterproof performance.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
