Description

[Technical Field]

[0001] The present invention relates to a wireless memory card and a wireless memory device, and more particularly to a wireless memory card and a wireless memory device capable of high-speed transmission. [Background technology]

[0002] Although RFID (Radio frequency identification) and NFC (Near field communication) are convenient and widely used wireless transmission technologies, they are limited in transmission speed and can only transmit small amounts of data. Therefore, data storage devices (e.g., memory cards) with a certain capacity or larger are generally designed for wired or contactless transmission. In other words, there are no wireless memory cards on the market. [Prior art documents] [Patent documents]

[0016] In order to fully understand the present invention, the following specific embodiments are shown and described in detail with the accompanying drawings. Those skilled in the art can understand the objectives, features, and advantages of the present invention from the contents disclosed in this specification. It should be noted that the present invention may be implemented or applied in other specific embodiments, and the details in this specification may be modified or changed from different perspectives, but they are within the scope of the present invention as long as they do not go against the spirit of the present invention. The following implementation methods further explain the technical content related to the present invention, but the disclosures do not limit the scope of the present invention.

[0017] The wireless memory card 100 of the first embodiment of the present invention shown in FIGS. 1 and 3 includes a substrate 1, a first wireless transceiver unit 2, a data storage unit 3 and a power unit 4.

[0018] The substrate 1 is the main body of the wireless memory card, and is preferably a printed circuit board. The printed circuit board is provided with multiple chip slots, allowing multiple electronic components to be mounted thereon. These electronic components are signal-connected and / or electrically connected to each other through the structure of the printed circuit board.

[0019] The first wireless transceiver unit 2 is disposed on the substrate 1. The first wireless transceiver unit 2 includes a first wireless controller 21 and a first wireless transceiver antenna 22, and the first wireless transceiver antenna 22 is signal-connected to the first wireless controller 21. The first wireless controller 21 is a wireless transmitting and receiving chip that uses the 60 GHz to 61 GHz band, and the first wireless transmitting and receiving antenna 22 is a transmitting and receiving antenna that uses the 60 GHz to 61 GHz band. The first wireless transmitting / receiving antenna 22 enables the first wireless controller 21 to transmit wireless signals to the outside and receive wireless signals from the outside. In this embodiment, the first wireless controller 21 and the first wireless transmitting / receiving antenna 22 are two independent components that are electrically connected to each other via a printed circuit board or an external circuit. However, the present invention is not limited to this. For example, in a wireless memory card 100a according to a second embodiment shown in FIG. 4, the first wireless controller 21 and the first wireless transmitting / receiving antenna 22 are integrated into a single element, i.e., the antenna is configured in a non-separable manner. The first wireless controller 21 and the first wireless transmitting / receiving antenna 22 integrated as a single element as described above can be incorporated into the substrate 1.

[0020] 1 and 3, the data storage unit 3 is disposed on the substrate 1 and is signal-connected to the first wireless controller 21. In this embodiment, the unit 3 is a flash memory chip, which allows data to be deleted, added, and overwritten multiple times. However, the present invention is not limited to this, and other embodiments may employ different types of storage, such as RAM or ROM.

[0021] The power unit 4 is disposed on the substrate 1 and is electrically connected to the first wireless transceiver unit 2. The power unit 4 is a unit that supplies the first wireless transceiver unit 2 with the power necessary for its operation. More preferably, in this embodiment, the power unit 4 is a wireless charging coil, which receives energy from an external supply device through inductive coupling and transfers power to the first wireless transceiver unit 2 . The power unit 4 as a wireless charging coil has the advantages of being lightweight, safe, and convenient, making it suitable for wireless memory card applications, but the present invention is not limited thereto, and in other embodiments, a power storage element such as a rechargeable battery may be provided on the substrate 1.

[0022] As described above, the wireless memory card 100 of the present invention employs a 60 GHz to 61 GHz wireless transmitting and receiving chip and transmitting and receiving antenna, achieving transmission speeds faster than USB 2.0. Therefore, combining the advantages of wireless transmission and high-speed transmission, and eliminating the need for wired or contact transmission, wireless memory cards are a viable next-generation memory option. Furthermore, because the wireless memory card 100 of the present invention employs a wireless transmission method, it can be sealed, achieving dustproof and waterproof protection while retaining transmitted data. The wireless memory card of the present invention can be used for corporate ID cards, factory records, hospital records, student ID cards, and any other card-shaped applications. The wireless memory card 100 of the present invention replaces traditional paper file management in companies, factories, and hospitals with card-based management, allowing everything to be recorded and stored on the card, and even encryption can be used.

[0023] Furthermore, the present invention, as shown in FIGS. 2 and 3, proposes a wireless memory device 200, which includes the above-mentioned wireless memory card 100 and a card reader 5.

[0024] The card reader 5 is connected to the wireless memory card 100 via a wireless signal in the 60 GHz to 61 GHz band. The specific shape and embodiment of the card reader 5 are not limited, and it may be an external reader device attached to the personal computer main body 6 or an electronic device built into the host device 6. Any device that can transmit and exchange data with the wireless memory card 100 using the 60 GHz to 61 GHz band can serve as the card reader 5.

[0025] Preferably, in this embodiment, the card reader 5 includes a second wireless controller 51 and a second wireless transmitting and receiving antenna 52. The second wireless transmitting and receiving antenna 52 is signal-connected to the second wireless controller 51, which is a wireless transmitting and receiving chip that uses the 60 GHz to 61 GHz band, and the second wireless transmitting and receiving antenna 52 is a transmitting and receiving antenna that uses the 60 GHz to 61 GHz band. The second wireless controller 51 can transmit wireless signals to the first wireless controller 21 and receive wireless signals from the first wireless controller 21 via the first wireless transmitting and receiving antenna 22 and the second wireless transmitting and receiving antenna 52.

[0026] Furthermore, in this embodiment, the card reader 5 includes a personal computer main body connection port 53, which is signal-connected to the second wireless controller 51. The main role of the personal computer main body connection port 53 is to transmit data from the wireless memory card 100 to the personal computer main body 6 for subsequent use. The personal computer main body connection port 53 may be, for example, a Universal Serial Bus (USB) or a Parallel Port.

[0027] Furthermore, in this embodiment, the wireless memory device 200 includes a personal computer 6, and the personal computer connection port 53 is signal-connected to the second wireless controller 51 via the personal computer 6. The personal computer 6 is a device equipped with a central processing unit, such as a desktop PC, a notebook PC, a network server, or a workstation.

[0028] Furthermore, the card reader 5 includes a wireless power supply unit 54, which is inductively coupled to the power unit 4. The wireless power supply unit 54 is also a wireless charging coil, which converts power from the computer main body 6 or another power source (e.g., commercial power) into a magnetic field, causing an induced current in the wireless charging coil of the power unit 4, thereby supplying power to the first wireless transceiver unit 2.
