Description
Technical Field
[0001] This utility model relates to the field of portable hard drive technology, and in particular to a portable hard drive that can improve the contrast of ambient light when using a computer at night. Background Technology
[0002] In the ongoing development of portable hard drives, in addition to focusing on core storage and transfer performance, improving the user experience has become an important consideration. To increase the fun and personalization of portable hard drives, some products have been equipped with ambient lighting. The original intention of these ambient lights is to create a unique visual atmosphere for users, thereby enhancing the user experience when using the portable hard drive.
[0003] However, in practical applications, especially during nighttime work in the absence of lights, these ambient lights reveal significant limitations. Because ambient lights typically lack strong brightness, they only serve a decorative purpose and cannot effectively enhance the brightness of the surrounding environment. When a user uses a computer at night with an external hard drive connected, if the surrounding environment is completely dark and only the computer screen provides light, the contrast between the screen and the surroundings becomes extremely high. The computer screen appears exceptionally bright relative to the surrounding environment, and this strong contrast causes the pupils to frequently and significantly contract and dilate. According to relevant research data, in this situation, when a user switches from looking at the screen to looking at the dark surroundings, the pupils quickly dilate to adapt to the darkness; and when the gaze returns to the screen, the pupils quickly constrict to adapt to the bright light. Such frequent changes put the eye muscles in a state of high tension, easily leading to eye fatigue, dryness, soreness, and other discomfort symptoms, and in the long run, may even affect vision.
[0004] Conversely, if the room has adequate lighting, the contrast between ambient light and computer screen light will decrease. In this case, the pupils do not need to undergo such drastic contraction and dilation, and the tension in the eye muscles will also be reduced. This can alleviate eye fatigue caused by changes in light contrast to some extent and reduce eye damage.
[0005] In conclusion, while mobile hard drive technology has met data storage needs and undergone technological evolution, it still faces challenges in user experience, such as insufficient ambient light brightness. These issues provide direction and basis for further optimization and innovation of mobile hard drive technology. Utility Model Content
[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.
[0007] A portable hard drive that improves ambient light contrast when using a computer at night includes a hard drive body with a casing and a main circuit board disposed within the casing. The main circuit board has a data transmission interface extending from the front of the casing. It also includes a raised lamp holder, which includes a lamp holder body that can be covered onto the hard drive body, a night light disposed at the lower end of the lamp holder body, and a power supply wire electrically connected between the night light and the main circuit board. A control switch electrically connected to the main circuit board is also disposed on the casing, and the control switch is used to control the night light. A swing arm fixing seat extends downwards at each of the four corners of the lamp holder body, and a swing support rod is hinged to the swing arm fixing seat. A docking port for engaging the swing arm fixing seat is disposed at each of the four corners of the casing. A double-track sliding groove is disposed on each side of the casing, with both ends of the double-track sliding groove engaging with the docking port. Two non-interfering sliding blocks are slidably connected to the double-track sliding groove. The swing support rod is hinged to the sliding block, and a compression spring is disposed within the double-track sliding groove to drive the sliding block to slide until its end abuts against the docking port.
[0008] Preferably, the main circuit board integrates a main control chip, a flash memory chip, a cache chip, and a power management chip. The flash memory chip, cache chip, power management chip, data transmission interface, power supply wires, and control switches are all electrically connected to the main control chip.
[0009] Preferably, the swing arm is configured such that when the swing arm fixing seat is mated with the mating socket, the end of the swing arm hinged to the swing arm fixing seat is deeper in the mating socket than the end of the swing arm hinged to the sliding block is in the mating socket.
[0010] Preferably, the swing arm is configured such that when the sliding block abuts the docking port, the swing arm is in an inclined state, so that when the heat dissipation body is pressed down, it can generate a component force on the sliding block that overcomes the compression spring.
[0011] Preferably, a concave-convex structure is provided between the inner wall of the swing arm fixing seat and the docking port, so that the swing arm fixing seat can be locked in place by the concave-convex structure after it is docked with the docking port.
[0012] Preferably, the double-track sliding groove has a first sliding groove and a second sliding groove. Two sliding blocks located on the same side of the outer shell are slidably connected in the first sliding groove and the second sliding groove, respectively. A blocking strip is provided on both sides of the first sliding groove and the second sliding groove, which abuts against the upper end of the sliding block. The two blocking strips of each sliding groove structure are spaced apart, so that the swing support rod can move between the two blocking strips.
[0013] Preferably, a blocking block is provided at the front end of the first slide groove and the rear end of the second slide groove. A spring rod is also provided on the sliding block. One end of the compression spring is sleeved on the spring rod, and the other end of the compression spring is pressed and engaged with the corresponding blocking block.
[0014] Preferably, a light groove is provided at the lower end of the raised light frame, and a light-transmitting cover is closed at the lower opening of the light groove, with the night light installed in the light groove.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] The hard drive body and the raised light stand are connected by swing rods at the four corners, and can be covered by each other when not in use. This design ensures that the portable hard drive will not increase its size or cause inconvenience due to the additional light stand structure during daily carrying, thus maintaining the original portability of the portable hard drive and making it convenient for users to carry the portable hard drive anytime and anywhere or move it between different places.
[0017] When lighting is needed at night, the main body of the lamp stand can be raised to a certain height. The night light at the bottom can create a certain atmosphere and illuminate the surrounding environment with strong brightness. Moreover, the light shines downwards, so it will not shine directly into the user's eyes, effectively avoiding eye discomfort caused by direct light, such as glare and dizziness. This allows users to clearly see their surroundings when using the external hard drive at night, making it convenient to perform operations such as plugging and unplugging data cables and checking the hard drive status.
[0018] This setup cleverly integrates the function of a desk lamp into the portable hard drive, providing users with lighting assistance. Whether using the portable hard drive in a dimly lit indoor environment or outdoors at night, it provides sufficient lighting support, meeting users' needs for ambient lighting around the portable hard drive in special environments.
[0019] The structure employs a swing arm support, a swing arm fixing seat, a sliding block, a sliding groove, and a compression spring. The swing arm fixing seat and the sliding block are hinged at both ends of the swing arm support, and the compression spring generates an elastic restraining force on the sliding block within the double-track sliding groove. After the lamp holder is raised, the compression spring allows the sliding block to abut against the docking port, keeping the swing arm upright. This keeps the raised lamp holder at a certain height above the hard drive body. The entire structure is simple and clear, and users can easily operate it without complicated steps or professional knowledge to raise and fix the lamp holder, thus enabling the lighting function.
[0020] The dual-track sliding groove structure allows for the installation of a sufficiently long swing support rod, enabling the lamp stand to be raised as high as possible within the limited size of the hard drive body. This better simulates the structure and lighting effect of a table lamp, thus meeting lighting needs while fully considering the size limitations of the portable hard drive itself. The overall structure will not appear bulky or unreasonable in pursuit of lighting functionality.
[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation
[0034] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0035] Please see Figure 1-9In this embodiment of the present invention, a portable hard drive that can improve the contrast of ambient light when using a computer at night includes a hard drive body 10. The hard drive body 10 has a shell 11 and a main circuit board 12 disposed inside the shell 11. The main circuit board 12 is provided with a data transmission interface 13 extending out of the front side of the shell 11. It also includes a lifting lamp holder 20, which includes a lamp holder body 21 that can be covered on the hard drive body 10, a night light 22 disposed at the lower end of the lamp holder body 21, and a power supply wire 23 electrically connected between the night light 22 and the main circuit board 12. A control switch 14 electrically connected to the main circuit board 12 is also provided on the shell 11. The control switch 14 is used to control the night light 22. When the user operates the control switch 14, the night light 22 can be turned on or off, so that the night light 22 can provide illumination at the appropriate time according to the user's needs. By adopting this high lamp stand structure and installing a night light 22 at the lower end of the raised lamp stand 20, the light generated by the night light 22 will not directly shine on the user during nighttime lighting. Instead, it will provide relatively bright lighting around the desktop by shining downwards, avoiding discomfort caused by direct light. At the four corners of the lamp stand body 21, there are swing arm fixing seats 24 extending downwards, and swing support rods 25 are hinged to the swing arm fixing seats 24. At the four corners of the outer shell 11, there are docking ports 15 for docking with the swing arm fixing seats 24. On both sides of the outer shell 11, there are double track sliding grooves 16. The two ends of the double track sliding grooves 16 are docked with the docking ports 15. Two non-interfering sliding blocks 17 are slidably connected on the double track sliding grooves 16. The swing support rods 25 are hinged to the sliding blocks 17. A compression spring 18 is installed in the double track sliding grooves 16 to drive the sliding blocks 17 to slide to their ends abutting against the docking ports 15.
[0036] By setting a lifting light stand 20 on the hard drive body 10, the lifting light stand 2020 and the hard drive body 10 are cleverly connected by utilizing the four corner positions, and the connection method is to use a swing support rod 25 to connect them, so that the hard drive body 10 and the lifting light stand 20 can cover each other when not in use, thereby achieving the purpose of easy portability.
[0037] When a certain amount of lighting is needed at night, by raising and holding the lamp stand 20, a certain distance is maintained between the lamp stand 20 and the hard drive body 10. When the night light 22 on the lamp stand 20 is working, it can create a certain atmosphere for the portable hard drive and provide strong brightness to illuminate the surrounding environment. Moreover, the light will not shine directly on the user. It is equivalent to a desk lamp cleverly combined with the portable hard drive, thereby providing the user with lighting assistance.
[0038] In terms of structural design, the system employs a swing support rod 25, a swing arm fixing seat 24, a sliding block 17, a sliding groove, and a compression spring 18. The swing support rod 25 is hinged at both ends to the swing arm fixing seat 24 and the sliding block 17, respectively. The sliding block 17 is then positioned within the double-track sliding groove 16 by the compression spring 18, generating a certain elastic restraint force. This allows the compression spring 18 to exert an elastic force on the sliding block 17 after the lamp holder 20 body is raised, causing the sliding block 17 to abut against the docking port 15, keeping the swing support rod 25 upright. The interaction of the four swing supports 25 maintains the lamp holder body 21 at a certain height above the hard drive body 10. This structure is simple and easy for users to operate. Furthermore, the double-track sliding groove 16 structure allows the swing support rod 25 to be set to a sufficient length, enabling the hard drive body 10 to raise the lamp holder body 21 as high as possible within limited dimensions, thus simulating the structure of a table lamp.
[0039] Please see Figure 9 In this embodiment of the invention, the main circuit board 12 integrates a main control chip 121, a flash memory chip 122, a cache chip 123, and a power management chip 124. The flash memory chip 122, cache chip 123, power management chip 124, data transmission interface 13, power supply wire 23, and control switch 14 are all electrically connected to the main control chip 121. When the user turns on the night light 22 via the control switch 14, the control switch 14 transmits the corresponding electrical signal to the main control chip 121. The main control chip 121 then allocates power to the night light 22 appropriately via the power supply wire 23 according to a preset program and the current power status, ensuring normal illumination. Regarding data transmission, when the portable hard drive interacts with external devices, the main control chip 121 can coordinate the flash memory chip 122 to perform data reading or writing operations based on external instructions received from the data transmission interface 13, and optimize the data transmission process with the help of the cache chip 123, ensuring fast, accurate, and stable data transmission.
[0040] Please see Figure 5In this embodiment of the invention, the swing support rod 25 is further configured such that when the swing arm fixing seat 24 is mated with the docking socket 15, the end of the swing support rod 25 hinged to the swing arm fixing seat 24 is positioned deeper in the docking socket 15 than the end of the swing support rod 25 hinged to the sliding block 17. This positioning allows the swing support rod 25 to form a "tilted" posture in the mated state, thus playing a role similar to a "diagonal brace" in the connection structure between the swing arm fixing seat 24 and the docking socket 15. When the portable hard drive may be subjected to external impact, vibration, or movement during daily use, the swing support rod 25 can better resist external forces due to this special positional relationship, preventing the swing arm fixing seat 24 from becoming loose or detached from the docking socket 15, thereby enhancing the stability of the entire connection structure between the raised lamp holder 20 and the hard drive body 10.
[0041] Please see Figure 7 In this embodiment of the present invention, the swing support rod 25 is further configured such that when the sliding block 17 abuts against the docking port 15, the swing support rod 25 is in an inclined state, so that when the lamp holder 20 is pressed down and raised, it can generate a component force on the sliding block 17 that overcomes the compression spring 18; when it is necessary to press down and raise the lamp holder 20, for example, to restore it to a state where it can be closed with the hard drive body 10 for easy carrying, the inclined state of the swing support rod 25 can generate a component force on the sliding block 17 that overcomes the elastic force of the compression spring 18. This means that when performing the pressing operation, the user does not need to apply too much external force to overcome the elastic force of the compression spring 18, because the component force generated by the swing support rod 25 is already assisting in pushing the sliding block 17, so that it can overcome the resistance of the spring relatively easily, thereby smoothly pressing the raised lamp holder 20 down to a suitable position to close with the hard drive body 10, which greatly improves the convenience of operation.
[0042] Please see Figure 6 and Figure 8 In this embodiment of the present invention, a concave-convex structure 26 is further provided between the inner wall of the swing arm fixing seat 24 and the docking port 15, so that the swing arm fixing seat 24 can be locked by the concave-convex structure 26 after docking with the docking port 15. The concave-convex structure 26 makes the swing arm fixing seat 24 and the docking port 15 form a tighter locking relationship after docking. Compared with the ordinary docking method, this locking can effectively prevent the swing arm fixing seat 24 and the docking port 15 from loosening due to external vibration, shaking or slight collision during the daily use of the mobile hard drive.
[0043] Please see Figure 3-8In this embodiment of the present invention, a double-track sliding groove 16 is further provided, comprising a first sliding groove 161 and a second sliding groove 162. Two sliding blocks 17 located on the same side of the outer casing 11 are slidably connected in the first sliding groove 161 and the second sliding groove 162, respectively. A blocking strip 163 is provided on both sides of the first sliding groove 161 and the second sliding groove 162, abutting against the upper end of the sliding block 17. The two blocking strips 163 of each sliding groove structure are spaced apart, allowing the swing support rod 25 to move between the two blocking strips 163. A blocking block 164 is provided at the front end of the first sliding groove 161 and the rear end of the second sliding groove 162. A spring rod 171 is also provided on the sliding block 17. One end of the compression spring 18 is sleeved on the spring rod 171, and the other end of the compression spring 18 is pressed and engaged with the corresponding blocking block 164. This installation method avoids the possible displacement or twisting of the spring during use, ensuring that the spring can always function in the predetermined manner, providing a stable elastic force for the entire structure.
[0044] Please see Figure 3 , Figure 5 and Figure 7 In this embodiment of the utility model, a lamp groove 27 is further provided at the lower end of the raised lamp holder 20, and a light-transmitting cover 28 is closed at the lower opening of the lamp groove 27. The night light 22 is installed in the lamp groove 27. The presence of the light-transmitting cover 28 can make the light emitted by the night light 22 more evenly scattered. The night light 22 is installed in the lamp groove 27. The light first passes through the refraction and scattering effect of the light-transmitting cover 28 before illuminating the surrounding environment. This can avoid the light being too concentrated or obvious light spots, making the light distribution in the lighting area softer and more uniform, providing users with a better visual experience, especially when using a portable hard drive at night, it can create a more comfortable lighting atmosphere.
[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
