Description

Technical Field

[0001] This invention relates to the field of PSSD technology, and more particularly to a PSSD with replaceable identifier content. Background Technology

[0002] Portable solid-state drives (SSDs) are widely used in daily life and work. Currently, most portable SSDs, especially those of the same model, have identical markings, making it difficult for users to identify their own drive when it's not plugged in and data is being read.

[0003] Especially when companies collect a large number of portable solid-state drives of the same model for their employees to use in the office, it is easy to get confused or take the wrong ones after they are borrowed, causing unnecessary trouble.

[0004] The current method of differentiation is to purchase and then customize a specific logo, such as a designated logo on a laser engraving or a corresponding logo printed on it. However, this method is not replaceable.

[0005] Alternatively, adhesive labels with specific markings can be used, and different adhesive labels can be replaced according to different markings. However, adhesive labels are easily damaged and are relatively monotonous. Summary of the Invention

[0006] To overcome the shortcomings mentioned above, the present invention aims to provide a technical solution to address the aforementioned problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a PSSD with replaceable identification content, comprising a hard disk casing, a main control unit, and a storage unit and a data interface electrically connected to the main control unit; It also includes an e-ink screen, which is mounted on the outside of the hard drive casing and is electrically connected to the main control unit; When the terminal device connects to the main control unit for data interaction via a data interface, the main control unit receives the display information transmitted by the terminal device and controls the changes in the display screen according to the display information. Even after a power outage, the e-ink screen retains the image displaying the corresponding information.

[0008] A further technical solution of the present invention: the displayed information includes identification display information; When the terminal device interacts with the main control unit through the data interface, the main control unit is also configured to determine the identity information of the terminal user; When a user is identified as a target user, the identification display information transmitted by the terminal device is stored or updated to the storage unit. Even after the terminal device is disconnected from the main control unit, the e-ink screen continues to display the image corresponding to the stored or updated identifier information.

[0009] A further technical solution of the present invention: the display information also includes the use of the display information; The main control unit also receives the usage display information transmitted by the terminal device. During the data interaction between the terminal device and the main control unit through the data interface, the main control unit controls the changes in the display screen of the e-ink screen according to the usage display information to display the usage.

[0010] A further technical solution of the present invention: when identified as a target user, it allows receiving and storing or updating the identification display information transmitted by the terminal device to the storage unit, and allows receiving the usage display information transmitted by the terminal device.

[0011] A further technical solution of the present invention: when a user is identified as a non-target user, the user is allowed to receive the usage display information transmitted by the terminal device, and is prohibited from receiving the identification display information transmitted by the terminal device or from storing or updating the identification display information transmitted by the terminal device to the storage unit.

[0012] A further technical solution of the present invention includes an auxiliary power supply; the auxiliary power supply is used to extend the power supply so that the main control unit controls the e-ink screen to change to display the screen corresponding to the label information when the connection between the main control unit and the terminal device is disconnected during the use and display process.

[0013] A further technical solution of the present invention: when the terminal device connects to the main control unit for data interaction through the data interface, the terminal device supplies power to the main control unit through the data interface; The auxiliary power supply includes an energy storage capacitor, which is charged when the main control unit receives power.

[0014] Compared with existing technologies, the advantages of this technical solution are: after power failure, the e-ink screen retains the displayed image corresponding to the information, forming the corresponding identification content on the outer side of the hard drive casing. Even after the PSSD is disconnected from the terminal device, the retained image content can be displayed, allowing users to easily identify the PSSD's ownership through the identification content; or, the identification content can be used for corresponding variable displays. Users can transmit corresponding display information to the main control unit according to different identification display needs, thus conveniently changing the identification display content.

[0015] Additional aspects and advantages of the 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

[0016] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] Figure 1 This is a three-dimensional structural view of the present invention; Figure 2 This is a circuit block diagram of the present invention; Figure 3 This is a flowchart illustrating the process of receiving display information according to the present invention. Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-3 A PSSD with replaceable identification content includes a hard drive casing 1, a main control unit 2, and a storage unit 3 and a data interface 4 electrically connected to the main control unit 2. The PSSD also includes an e-ink screen 5, which is disposed on the outside of the hard drive casing 1 and electrically connected to the main control unit 2.

[0020] When the terminal device connects to the main control unit 2 via the data interface 4 for data interaction, the main control unit 2 receives the display information transmitted by the terminal device and controls the display screen 5 according to the display information.

[0021] E-ink displays use electronic ink technology, which is based on the principle of electrophoresis. Electronic ink consists of millions of microcapsules, each containing charged colored particles. When a voltage is applied to the screen, the colored particles move to the top of the microcapsules, forming an image. Unlike traditional display technologies, electronic ink particles remain in a fixed position due to hysteresis after an electric field is applied; that is, the displayed image is retained even after the power is turned off.

[0022] After power failure, the e-ink screen retains the displayed image corresponding to the information, forming a label on the outer casing of the hard drive. Even after the PSSD is disconnected from the terminal device, the retained image content can be displayed, allowing users to easily identify the PSSD's ownership; or, the label content can be used for various variable displays. Users can easily change the displayed label content by transmitting corresponding display information to the main control unit according to different label display needs.

[0023] In some embodiments, the displayed information includes identification display information.

[0024] When the terminal device interacts with the main control unit via a data interface, the main control unit is also configured to determine the identity information of the terminal user. Upon identification as a target user, the identification display information transmitted by the terminal device is stored or updated to the storage unit.

[0025] Even after the terminal device is disconnected from the main control unit, the e-ink screen continues to display the image corresponding to the stored or updated identifier information.

[0026] In some embodiments, the display information may also include the use of display information.

[0027] The main control unit also receives the usage display information transmitted by the terminal device. During the data interaction between the terminal device and the main control unit through the data interface, the main control unit controls the changes in the display screen of the e-ink screen according to the usage display information to display the usage.

[0028] In some embodiments, when identified as a target user, it is permissible to receive and store or update the identification display information transmitted by the terminal device to the storage unit, and to receive the usage display information transmitted by the terminal device.

[0029] In some embodiments, when a user is identified as a non-target user, the user is allowed to receive usage display information transmitted by the terminal device, and is prohibited from receiving identification display information transmitted by the terminal device or from storing or updating identification display information transmitted by the terminal device to the storage unit.

[0030] In this embodiment, by recognizing the user's identity, personalized usage display can be achieved through the use of display information during data interaction between the PSSD and the terminal device. At the same time, even after the connection between the terminal device and the main control unit is disconnected, the e-ink screen can effectively ensure that the displayed image remains strongly associated with the target user. This avoids non-target users accidentally changing the identification display information, which could lead to the PSSD being misidentified by other users. It also makes it easier for the target user to confirm and retrieve the device, or avoids displaying a screen that does not match the target user's image after borrowing.

[0031] In some embodiments, the PSSD further includes an auxiliary power supply 6, which is used to extend the power supply so that the main control unit 2 can control the e-ink screen 5 to change to display the screen corresponding to the information displayed on the label when the connection between the main control unit and the terminal device is disconnected during the display process.

[0032] In some embodiments, when the PSSD interacts with the terminal device, the terminal device also supplies power to the PSSD through the data interface 4. Correspondingly, when the PSSD is powered, the auxiliary power supply 6 is charged.

[0033] Specifically, the auxiliary power supply 6 includes an energy storage capacitor. When the terminal device connects to the main control unit 2 via the data interface 4 for data interaction, the terminal device supplies power to the main control unit 2 via the data interface 4; when the main control unit 2 receives power, the energy storage capacitor is charged accordingly.

[0034] After the PSSD is disconnected from the terminal device, the terminal device disconnects the power supply to the PSSD. At this time, the energy charged by the energy storage capacitor is supplied to the main control unit and the e-ink screen to extend the control time of the main control unit on the e-ink screen.

[0035] After the main control unit confirms that the PSSD is disconnected from the terminal device, the main control unit controls the e-ink screen to change to display the image corresponding to the identification display information stored or updated to the storage unit. After that, the auxiliary power supply is exhausted, and through the characteristics of the e-ink screen, the image becomes a persistent identification image.

[0036] In some embodiments, when the terminal device transmits display information to the PSSD in the form of an APP installed on the terminal device: the APP has a user login window, or a user information verification pop-up window when selecting to transmit the identifier display information; after logging in with the specified user login information or entering the specified user verification information, the current user is identified as the target user; otherwise, it is determined to be a non-target user.

[0037] In some embodiments, after user login information or user verification information is entered, the terminal device transmits the user login information or user verification information to the main control unit. The main control unit compares the received user login information or user verification information with the target user login information or target user information stored in the storage unit. If the comparison is successful, the current user is identified as the target user.

[0038] Correspondingly, the system receives the identification display information transmitted by the logged-in user or receives the identification display information transmitted in this transmission, and stores or updates the identification display information transmitted by the target user to the storage unit.

[0039] In some embodiments, after successfully identifying the current user as the target user, confirmation information identifying the target user is sent back to the terminal device.

[0040] In some embodiments, the terminal device is, for example, a mobile phone, a laptop, a tablet, or a desktop computer, and can control the display screen of the e-ink screen on the PSSD by installing the aforementioned APP.

[0041] 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 invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
