Description

Technical Field

[0001] This invention relates to the field of portable hard drive protection technology, specifically a portable hard drive with power failure protection function. Background Technology

[0002] A portable hard drive uses a hard drive as its storage medium, enabling the exchange of large amounts of data between computers. It can be plugged in or unplugged at any time, is small and easy to carry, and can transfer data with the system at a relatively high speed. It is a storage product that emphasizes portability.

[0003] According to the portable hard drive disclosed in application number CN202123432253.0, its technical solution is: "A portable hard drive includes: a shell with a cavity and a vent hole communicating with the cavity; a bracket disposed in the cavity and detachably connected to the shell; a PCB board disposed in the cavity and mounted on the bracket, the PCB board including a chip; a heat-conducting component on one side in contact with the chip; and a heat sink fixedly connected to the heat-conducting component on the other side away from the chip." The beneficial effect of this technology is that the vent hole is provided on the shell, and the heat-conducting component and heat sink are mounted in contact with the chip. During the use of the portable hard drive, the heat generated by the chip can be quickly transferred to the heat sink through the heat-conducting component and exchanged with the air entering through the vent hole, thus dissipating the heat. This effectively dissipates heat from the chip during operation, allowing it to operate at a suitable temperature and improving the overall performance of the portable hard drive.

[0004] However, the aforementioned patents can only solve the basic heat dissipation problem of current portable hard drives. When the hard drive is used for a long time, or in a hot environment, or when the device malfunctions and causes the hard drive temperature to rise sharply in a short period of time, it is easy to damage the hard drive.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. While the heat dissipation mechanism is blowing air to dissipate heat, it is linked with the power-off mechanism. This causes the fixed shaft of the power-off mechanism to continuously drive the propeller blades to rotate and blow air. When the air blown towards the sealed cylinder cannot be discharged in the reverse direction, the blown air directly pushes the first mounting plate and the iron plate on its outer side towards the electromagnet and magnetically attracts it. When the temperature sensor detects that the temperature has reached the set power-off temperature value, the motor is automatically shut off, causing the heat dissipation mechanism to stop its linkage with the power-off mechanism. Consequently, the fixed shaft also stops driving the propeller blades to rotate. Then, due to the lack of air propulsion, the first spring rebounds and contracts to reset, which in turn drives the first mounting plate, the iron plate, and the electromagnet to move. The electromagnet then drives the second mounting plate and the support tube to move towards the first mounting plate, and the support tube simultaneously drives the fixed plate to move. The fixed plate then moves the magnetic data plug away from the magnetic data connector, effectively enabling automatic power-off when the temperature is too high, stopping data transmission, and preventing damage to the hard drive body and loss of internally stored files. This effectively improves the efficiency of power-off protection and further enhances the user experience.

[0017] 2. The system uses a removable filter to initially filter dust, followed by a polyurethane filter to remove even finer dust particles, effectively improving dust prevention. Furthermore, the exhaust mechanism vents air when the hard drive is in use and seals it for dust prevention when not in use, further enhancing dust protection. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] A heat dissipation mechanism 5 and a power-off mechanism 6 are installed at the top of the inner cavity of the upper housing 1.

An integrated air-collecting sleeve 511 is connected at the top of the inner cavity of the upper housing 1. The motor 51 is located inside the air-collecting sleeve 511. By starting the motor 51, the output end of the motor 51 drives the multiple sets of fan blades 52 to rotate, which facilitates the blowing and heat dissipation of electronic components such as the hard disk body 14. It also draws room temperature air filtered by the dustproof component 3 into the space between the upper housing 1 and the lower housing 2, effectively cooling the inner cavity temperature of the upper housing 1 and the lower housing 2. Furthermore, the design of the air-collecting sleeve 511 effectively improves the effect of drawing in ambient room temperature air, making it convenient to use.

[0033] A fixed cover 57 is connected to one side of the wind-gathering sleeve 511. The fixed cover 57 is connected to the wind-gathering sleeve 511. The bottom of the inner cavity of the fixed cover 57 is rotatably connected to the drive shaft 54 ​​through the first bearing seat 53. The output end of the drive shaft 54 ​​and the motor 51 are both equipped with first pulleys 55. The first pulleys 55 are connected together by a first transmission belt 56. The upper end of the drive shaft 54 ​​passes through the fixed cover 57 and extends above it. A fixed sleeve 58 is installed at the top of the inner cavity of the upper housing 1 and is movably sleeved therewith. The power-off mechanism 6 includes a second bearing seat 61 installed at the top of the inner cavity of the upper housing 1. The inner cavity of the second bearing seat 61 is rotatably connected to the fixed shaft 62. The outer side of the fixed shaft 62 and the drive shaft 54 ​​are both equipped with second pulleys 59. The second pulleys 59 are connected together by a second transmission belt 510. Propeller blades 63 are equidistantly installed on the outer side of the fixed shaft 62. The inner cavity of the upper housing 1 A conical cover 65 is connected via a support frame 64. A propeller blade 63 is located inside the conical cover 65. A sealing cylinder 66 is installed at the lower end of the conical cover 65. An installation sleeve 67 is installed inside the sealing cylinder 66. A first mounting plate 69 is connected to one side of the installation sleeve 67 via a first spring 68. An iron sheet 610 is bonded to one side of the first mounting plate 69. The size of the first mounting plate 69 matches the inner diameter of the sealing cylinder 66. A support tube 611 is movably inserted into one side of the sealing cylinder 66. A second mounting plate 613 is connected to one side of the support tube 611. An electromagnet 612 is bonded to one side of the second mounting plate 613. A second spring 614 is connected between the inner cavity of the sealing cylinder 66 and the second mounting plate 613. A fixing plate 615 is connected to one side of the support tube 611. Both the first mounting plate 69 and the second mounting plate 613 are made of insulating material, and the support tube 611 is made of plastic material.

[0034] A slot is provided on one side of the lower housing 2. An interface component 7 corresponding to the slot is installed at the bottom of the inner cavity of the lower housing 2. The interface component 7 is connected to the power-off mechanism 6. The interface component 7 includes a concave seat 71 installed at the bottom of the inner cavity of the lower housing 2. A baffle 72 is connected to the upper end of the concave seat 71. A magnetic data connector 74 is installed at the upper end of the concave seat 71. A magnetic data plug 75 is magnetically connected to one side of the magnetic data connector 74. The upper end of the magnetic data plug 75 is connected to the fixing plate 615. A slide rail 73 is integrally provided in the inner cavity of the concave seat 71. A sliding groove 76 is provided at the lower end of the magnetic data plug 75 for sliding contact with it.

[0035] The output of motor 51 drives the first pulley 55 on its outer side to rotate synchronously. The first pulley 55 drives another first pulley 55 and its inner drive shaft 54 ​​to rotate via the first transmission belt 56. The transmission shaft 54, through the second pulley 59 on its outer side, drives another second pulley 59 and its inner fixed shaft 62 to rotate synchronously via the second transmission belt 510. The fixed shaft 62 synchronously drives multiple propeller blades 63 to rotate. A conical cover 65 is designed on its outer side to facilitate the accumulation of airflow drawn in by the propeller blades 63 during continuous rotation, which is then transmitted to the sealing cylinder 66. Because the inner cavity of the sealing cylinder 66 is equipped with a first mounting plate 69 that matches the inner diameter, the first... The obstruction of the mounting plate 69 prevents the airflow blowing towards the sealing cylinder 66 from continuing forward. Since the inner diameter of the sealing cylinder 66 is smaller than the inner diameter of the lowest point of the conical cover 65, when the fixed shaft 62 continuously drives the propeller blade 63 to rotate, the airflow blowing towards the sealing cylinder 66 cannot be expelled in the reverse direction. Therefore, the blown air directly pushes the first mounting plate 69 and its outer iron plate 610 towards the electromagnet 612, and magnetically attracts it to the activated electromagnet 612. The first mounting plate 69 then stretches the first spring 68. When the temperature sensor 13 detects that the temperature has reached the set power-off temperature value, it transmits this information to the control module 12, thereby controlling the module 12 to automatically shut off the motor 51, thus reducing the output of the motor 51. When the end stops driving the fan blade 52 to rotate, the transmission shaft 54 ​​also stops driving, and subsequently the fixed shaft 62 also stops driving the propeller blade 63 to rotate, thus stopping the input of air force to the inner cavity of the sealing cylinder 66. At this time, the first mounting plate 69 has no thrust, and the elastic stiffness of the first spring 68 is greater than the magnetic attraction force of the electromagnet 612 and the elastic stiffness of the second spring 614. Therefore, the first spring 68 rebounds and contracts to return to its original position, and then drives the first mounting plate 69, the iron plate 610 and the electromagnet 612 to move. The electromagnet 612 then drives the second mounting plate 613 and the support tube 611 to move towards the first mounting plate 69, and simultaneously stretches the second spring 614. The support tube 611, made of plastic material, is designed to reduce its weight and facilitate its movement. As the second mounting plate 613 moves, the first mounting plate 69 and the second mounting plate 613, made of insulating material, prevent the magnetic force from affecting the normal and stable operation of the first spring 68 and the second spring 614, effectively improving the performance. At this time, the support tube 611 synchronously drives the fixing plate 615 to move, and the fixing plate 615 drives the magnetic data plug 75 away from the magnetic data connector 74. The magnetic data plug 75 slides on the outside of the slide rail 73 through the slide groove 76, effectively improving the stability of the movement of the magnetic data plug 75. This effectively enables automatic power-off and stops data transmission when the temperature is too high, preventing damage to the hard drive body 14, loss of internally stored files, and impact on usability.

[0036] The lower housing 2 has through holes 15 around its lower end, and each through hole 15 has a circular groove 16 communicating with it. An exhaust mechanism 8 is installed around the bottom of the inner cavity of the lower housing 2. The lower end of the exhaust mechanism 8 passes through the through hole 15 and extends into the inner cavity of the circular groove 16. The exhaust mechanism 8 includes two support columns 81 installed at the bottom of the inner cavity of the lower housing 2. A movable sleeve 83 is movably sleeved at the upper end of each support column 81. A third spring 89 is connected between the movable sleeve 83 and the bottom of the inner cavity of the lower housing 2. One side of the movable sleeve 83 is integrated with a connecting rod 84. The two connecting rods 84 are connected together to a sealing disc 85. The sealing disc 85 is located in the inner cavity of the through hole 15. The size of the sealing disc 85 matches the inner diameter of the through hole 15. The lower end of the sealing disc 85 is connected to a base 87 through a connecting column 86. Half of the base 87 is located in the inner cavity of the circular groove 16. The lower outer side of the base 87 is provided with equidistant vent holes 88. The vent holes 88 are L-shaped. The upper end of the support column 81 is equipped with a limit plate 82.

[0037] When this hard drive is in use, the lower housing 2 is placed on a table, and the base 87 at the lower end of the lower housing 2 first contacts the table. Then, due to the weight of the hard drive, the upper part of the base 87 enters the circular groove 16 of the lower housing 2. The upper end of the base 87 drives the sealing plate 85 to move upward through the connecting post 86 and leave the through hole 15 to enter the inner cavity of the lower housing 2. At the same time, the sealing plate 85 drives the movable sleeve 83 to move upward through the connecting rod 84. The movement is limited and protected by the limiting plate 82. Then, the movable sleeve 83 synchronously stretches the third spring 89, and then the lower housing 2 drives the upper... The housing 1 and other components are moved down, and the lower housing 2 is connected to the exhaust port 88 in the base 87 through the through hole 15. This allows the hot air between the upper housing 1 and the lower housing 2 to be discharged to the outside through the through hole 15 to the multiple exhaust ports 88 when the heat dissipation mechanism 5 is blowing heat. This effectively improves the heat dissipation effect. When the hard drive is not in use, after it is removed from the table, the third spring 89 returns to its original position, causing the sealing plate 85 to return to its original position and seal, which effectively improves the dust prevention effect. When storing, it can be placed upside down with the upper housing 1 facing down to effectively prevent dust.

[0038] Working principle: This invention connects the battery 11 to the switch 10, which in turn connects to the control module 12. The control module 12 is then connected to the display screen 4, motor 51, electromagnet 612, and temperature sensor 13 via a control programming connection. A Type-C charging port (not shown in the attached diagram) is provided on the outside of the lower housing 2 and connected to the battery 11 for convenient charging. The hard drive body 14 is connected to the magnetic data plug 75 via a data cable. In use, the lower housing 2 is placed on a table. Due to the weight of the hard drive, the upper part of the base 87 enters the circular groove 16 of the lower housing 2. The upper end of the base 87 moves the sealing plate 85 upward through the connecting post 86, and then moves it out of the through hole 15 and into the lower housing. The inner cavity of body 2 is simultaneously filled with the sealing disc 85, which drives the movable sleeve 83 to move upward via the connecting rod 84. This causes the movable sleeve 83 to simultaneously stretch the third spring 89, subsequently causing the lower housing 2 to move downward along with components such as the upper housing 1. The lower housing 2 is connected to the exhaust port 88 in the base 87 via the through hole 15. Pressing the switch 10 activates the control module 12, which automatically turns on the display screen 4, motor 51, electromagnet 612, and temperature sensor 13. The output of motor 51 then drives multiple sets of fan blades 52 to rotate, facilitating airflow cooling for electronic components such as the hard drive body 14. It also draws in ambient temperature air filtered by the dustproof component 3 between the upper housing 1 and the lower housing 2, effectively regulating the temperature within the inner cavities of the upper housing 1 and the lower housing 2. The system is cooled to a certain temperature, and the design of the air-collecting sleeve 511 effectively improves the intake of ambient air, making it easy to use. Simultaneously, hot air between the upper housing 1 and the lower housing 2 is discharged to multiple exhaust holes 88 through the through hole 15, thus effectively improving heat dissipation. When the hard drive is not in use and is removed from the table, the third spring 89 returns to its original position, causing the sealing disk 85 to return to its original position for sealing, effectively improving dust prevention. The output of the motor 51 drives the first pulley 55 on its outer side to rotate synchronously. The first pulley 55 drives another first pulley 55 and its inner drive shaft 54 ​​via the first transmission belt 56. The drive shaft 54, via its outer second pulley 59 and the second transmission belt 56, rotates. 10 synchronously drives another second pulley 59 to rotate with its inner cavity fixed shaft 62. The fixed shaft 62 synchronously drives multiple propeller blades 63 to rotate. A conical cover 65 is designed on its outer side to facilitate the accumulation of airflow drawn in by the propeller blades 63 during continuous rotation, which is then transferred to the sealing cylinder 66. Because the inner cavity of the sealing cylinder 66 is equipped with a first mounting plate 69 matching its inner diameter, the first mounting plate 69 prevents the airflow blowing towards the sealing cylinder 66 from continuing forward. Furthermore, because the inner diameter of the sealing cylinder 66 is smaller than the inner diameter of the lowest point of the conical cover 65, when the fixed shaft 62 continuously drives the propeller blades 63 to rotate, the airflow blowing towards the sealing cylinder 66 cannot be discharged in the opposite direction. Therefore...The blown air directly pushes the first mounting plate 69 and its outer iron plate 610 towards the electromagnet 612, and they are magnetically attracted to the activated electromagnet 612. The first mounting plate 69 then stretches the first spring 68. When the temperature sensor 13 detects that the temperature has reached the set warning temperature value, it transmits this information to the control module 12, which then displays a warning alarm on the display screen 4 to remind the user. When the temperature sensor 13 detects that the temperature has reached the set power-off temperature value, it transmits this information to the control module 12, which then controls the module 12 to automatically shut off the motor 51. Consequently, the output of motor 51 stops driving fan blade 52 to rotate, and the transmission shaft 54 ​​also stops driving. Then, fixed shaft 62 stops driving propeller blade 63 to rotate, thus ceasing the input of airflow into the inner cavity of sealing cylinder 66. At this point, the first mounting plate 69 has no thrust, and the elastic stiffness of the first spring 68 is greater than the magnetic attraction force of electromagnet 612 and the elastic stiffness of the second spring 614. Therefore, the first spring 68 rebounds and retracts to its original position, subsequently moving the first mounting plate 69, iron plate 610, and electromagnet 612. Electromagnet 612 then moves the second mounting plate 613 and support tube 611 towards the first mounting plate 69. The second spring 614 is simultaneously stretched, and the support tube 611, made of plastic material, is used to reduce its weight and facilitate its movement with the second mounting plate 613. The first mounting plate 69 and the second mounting plate 613, made of insulating material, are used to prevent magnetic forces from affecting the normal and stable operation of the first spring 68 and the second spring 614, effectively improving the performance. At this time, the support tube 611 synchronously drives the fixed plate 615 to move, and the fixed plate 615 drives the magnetic data plug 75 away from the magnetic data connector 74, thereby effectively enabling automatic power-off and stopping data transmission when the temperature is too high, preventing the hard drive body 14 from being damaged. Damage to the internally stored files caused by the device results in data loss, affecting usability. However, when the temperature sensor 13 detects that the temperature has dropped to the set value, it automatically shuts off the electromagnet 612, disengaging the magnetic attraction between the electromagnet 612 and the iron plate 610. At this point, the stretched second spring 614 resets the second mounting plate 613 and the electromagnet 612. The second mounting plate 613 then moves the magnetic data plug 75 towards the magnetic data connector 74 via the fixing plate 615 until they magnetically attract each other, effectively enabling power supply. Simultaneously, the motor 51 is activated, allowing the heat dissipation mechanism 5 to continue its cooling operation, effectively improving usability.
