Description

Technical Field

[0001] This utility model relates to the field of card reader technology, specifically a multi-functional card reader. Background Technology

[0002] A card reader is a device for reading cards. Due to the wide variety of card types, the term "card reader" has a broad meaning. Based on the card type, they can be categorized into IC card readers, including contact IC card readers (compliant with the ISO7816 interface standard), contactless IC card readers (compliant with the ISO14443 interface standard), and long-range card readers (compliant with the ETC national standard GB20851 interface standard).

[0003] Because there are various types of card readers available, different types of memory cards require different card readers, which is extremely inconvenient during use. Moreover, existing card readers lack effective dust protection, making them highly susceptible to the intrusion of external dust and impurities when not in use, which can cause internal damage.

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a multi-functional card reader. Utility Model Content

[0005] The purpose of this invention is to provide a multi-functional card reader to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-functional card reader includes a multi-port card reader with a Type-C connector and a USB connector at both ends. One side wall has a standard SD card slot, a MiniSD card slot, and a TF card slot along its length. A set of Apple connectors is retracted into the middle of the side wall corresponding to the standard SD card slot, MiniSD card slot, and TF card slot. Data exchange between different types of memory cards and the multi-port card reader is achieved through the standard SD card slot, MiniSD card slot, and TF card slot. Simultaneously, by utilizing the different signal connectors of the Type-C connector, USB connector, and Apple connector, data signal transmission connections between the multi-port card reader and different systems such as Android, Windows, and Apple can be established, thereby significantly improving the applicability of this card reader. A rectangular frame structure rotating protective shell is rotatably connected to the outside of the multi-port card reader. The rotating protective shell has telescopic ends. It features two sets of positioning sleeves, each with an opening on one side facing the end of the multi-hole card reader. By swinging the positioning sleeves to both ends of the multi-hole card reader, its extension and retraction are controlled, allowing its openings to fit over the Type-C and USB connectors. This protects the unused Type-C and USB connectors while keeping the rotating protective shell relatively stationary with respect to the multi-hole card reader, providing protection within a certain range. Each of the standard SD card slot, MiniSD card slot, and TF card slot has a set of elastic protective elements on one side. When in a free state, these elements fall and automatically close the openings of the standard SD card slot, MiniSD card slot, and TF card slot. When a memory card needs to be inserted, the elastic protective elements are manually moved away from the openings before insertion. The elastic protective elements automatically provide dust protection for the standard SD card slot, MiniSD card slot, and TF card slot.

[0008] Compared with the prior art, the beneficial effects of this utility model are: by setting a standard SD card slot, a MiniSD card slot, and a TF card slot on the multi-port card reader, and cooperating with a Type-C connector, a USB connector, and an Apple connector, it is convenient to plug different types of memory cards into different types of devices for data transmission and interaction, thereby improving the applicability of this memory card;

[0009] By rotating a set of protective shells on the outside of the multi-port card reader, and using positioning sleeves at both ends of the protective shells to protect the Type-C connector and USB connector, and taking advantage of the inherent protective features of the Apple connector, the connector is stored in the storage hole, which greatly improves the protection of the Type-C connector, USB connector, and Apple connector. At the same time, an automatically closing elastic baffle is set on the outside of the standard SD card slot, MiniSD card slot, and TF card slot to further improve the dust protection effect of the standard SD card slot, MiniSD card slot, and TF card slot.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5A multi-functional card reader includes a multi-port card reader 10. The multi-port card reader 10 has a Type-C connector 13 and a USB connector 14 at both ends. One side wall has a standard SD card slot 19, a Mini SD card slot 20, and a TF card slot 21 along its length. A set of Apple connectors 15 is retracted in the middle of the side wall corresponding to the standard SD card slot 19, Mini SD card slot 20, and TF card slot 21. The card reader can access the standard SD card slot 19, Mini SD card slot 20, and TF card slot 21 via the USB connector 14. The SD card slot 20 and TF card slot 21 enable data exchange between different types of memory cards and the multi-port card reader 10. Simultaneously, by utilizing the different signal connectors of the Type-C connector 13, USB connector 14, and Apple connector 15, data signal transmission connections between the multi-port card reader 10 and different systems such as Android, Windows, and Apple can be achieved, thereby significantly improving the applicability of this card reader. A set of rectangular frame structure rotating protective shells 11 are rotatably connected to the outside of the multi-port card reader 10. Two sets of positioning sleeves 27 are telescopically arranged at both ends of the rotating protective shell 11. The positioning sleeves 27 have openings on the side facing the end of the multi-port card reader 10. When the positioning sleeves 27 are swung to the ends of the multi-port card reader 10, their extension and retraction are controlled, allowing their openings to fit onto the Type-C connector 13 and USB connector 14, thus protecting the unused Type-C connector 13 and USB connector 14. This keeps the rotating protective shell 11 and the multi-port card reader 10 in a relatively stationary state, providing protection to the multi-port card reader 10 within a certain range. Each of the standard SD card slot 19, MiniSD card slot 20, and TF card slot 21 has a set of elastic protective components on one side. When the elastic protective components are in a free state, they fall down and automatically close the openings of the standard SD card slot 19, MiniSD card slot 20, and TF card slot 21. When it is necessary to insert a memory card, simply move the elastic protective components away from the openings and insert the card. The elastic protective components can automatically protect the standard SD card slot 19, MiniSD card slot 20, and TF card slot 21 from dust.

[0022] In this embodiment of the invention, a base 16 is connected to one side of the bottom of the Apple connector 15, and a connecting wire 18 is connected to one side of the base 16. A storage hole 17 is provided on the side wall of the multi-hole card reader 10 corresponding to the connecting wire 18. The inner end of the connecting wire 18 is connected to the corresponding component inside the multi-hole card reader 10. At the same time, the diameter of the storage hole 17 is larger than that of the base 16 and the depth is larger than that of the Apple connector 15, so that the Apple connector 15 can be stored in the storage hole 17. Since the base 16 is different from the Type-C connector 13 and the USB connector 14, its exterior adopts a solid structure, so there is no need to worry about the influence of external dust on the Apple connector 15. Therefore, the Apple connector 15 can be directly stored in the storage hole 17.

[0023] Specifically, a magnetic layer is provided on the outer wall of the base 16, and a magnetic ring is provided at the corresponding position in the inner wall of the storage hole 17 to attract the magnetic strip layer. After the base 16 is placed inside the storage hole 17, the magnetic connection between the magnetic ring and the magnetic layer is used to ensure the stability of the Apple connector 15 in storage and the convenience of taking it out.

[0024] It should be noted that the Type-C connector 13, USB connector 14, and Apple connector 15 are connected to the main control chip inside the multi-port card reader 10 via wires or PCB (printed circuit board) traces; the standard SD card slot 19, MiniSD card slot 20, and TF card slot 21 have spring-loaded metal contacts corresponding to the pins of the memory card, which directly contact the metal terminals of the memory card for connection. The specific connection and operating principle can be easily achieved with the help of existing technology, and will not be elaborated here.

[0025] In one embodiment of the present invention, the upper and lower sides of the middle part of the multi-hole card reader 10 are rotatably connected to the rotating protective shell 11 via rotating shafts 12, and the width and length of the rotating protective shell 11 are both greater than those of the multi-hole card reader 10, ensuring that it can rotate freely around the multi-hole card reader 10.

[0026] The outer side of the open end wall of the positioning sleeve 27 extends outward to prevent it from slipping off the end of the rotating protective housing 11. At the same time, the closed end of the positioning sleeve 27 is equipped with an anti-detachment plate 28 with an area larger than the end wall of the positioning sleeve 27, which is also used to prevent the positioning sleeve 27 from slipping off the rotating protective housing 11.

[0027] Specifically, in order to ensure that the positioning sleeve 27 is stably fitted onto the Type-C connector 13 and the USB connector 14, and to facilitate disassembly, a magnetic strip is installed on the side of the anti-detachment plate 28 facing the rotating protective shell 11. A magnetic positioning groove 29 is formed on the outer wall of the rotating protective shell 11 corresponding to the magnetic strip. After the positioning sleeve 27 is completely fitted onto the Type-C connector 13 and the USB connector 14, the magnetic strip and the magnetic positioning groove 29 are magnetically connected and positioned.

[0028] As a preferred embodiment of the present invention, see [reference]. Figure 6Taking the elastic protective component at the standard SD card slot 19 as an example, the elastic protective component includes an elastic baffle storage box 22 installed on one side of the outer wall of the standard SD card slot 19. The bottom of the elastic baffle storage box 22 is open. Inside the elastic baffle storage box 22, a set of elastic baffles 23 are installed in a lifting manner. The top of the elastic baffles 23 inside the elastic baffle storage box 22 is equipped with a connecting block 24 whose width is larger than the size of the bottom opening of the elastic baffle storage box 22. The top of the connecting block 24 is elastically connected to the inner wall of the elastic baffle storage box 22 by a return spring 25. When the return spring 25 is in a free state, it controls the elastic baffles 23 to fall down and close the corresponding opening of the standard SD card slot 19. When it needs to be opened for use, simply push the elastic baffles 23 manually toward the inside of the elastic baffle storage box 22, and then insert the standard SD card into the standard SD card slot 19.

[0029] A sealing layer 26 is provided on the side of the elastic baffle 23 facing the opening of the standard SD card slot 19, and the sealing layer 26 is used to increase the sealing degree between the elastic baffle 23 and the opening of the standard SD card slot 19.

[0030] The working principle of this utility model is as follows: In the idle position of this device, all the aforementioned driving components, referring to power elements, electrical components, and compatible power supplies, are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without explaining the electrical control. During use, depending on the type of memory card, it is inserted into the corresponding standard SD card slot 19, MiniSD card slot 20, or TF card slot 21. Then, according to the interface type of the device to be connected for transmission, the Type-... The Type-C connector 13, USB connector 14, or Apple connector 15 are plugged in for data transmission. When not in use, the positioning sleeves 27 at both ends of the protective shell 11 are inserted into the Type-C connector 13 and USB connector 14 respectively by rotating the protective shell 11 to protect them. At the same time, the Apple connector 15 is stored in the storage hole 17. The reset spring 25 is in a free state, which controls the elastic baffle 23 at the bottom to close the outer side of the standard SD card slot 19, MiniSD card slot 20, and TF card slot 21, thereby achieving effective protection for each structural position.

[0031] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
