[0040] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0041] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0042] The description of this utility model is not restrictive. Figure 1 The markings “front,” “back,” “up,” “down,” “left,” and “right” shown are for facilitating understanding of this embodiment and are not intended to limit the present invention. Specifically, front-back indicates longitudinal direction, left-right indicates lateral direction, and up-down indicates vertical direction.

[0043] In this application, electronic terminals include terminal devices with specific electronic functions such as personal communication terminals, laptop terminals, video game terminals, and wearable electronic products, and this application does not limit them.

[0044] The card holder adapted to electronic terminals in this application is designed to be convenient to use with electronic terminals, serving as an accessory or ecosystem product for electronic terminals. On the other hand, even when detached from the electronic terminal, the card holder can be easily located through wireless communication with the electronic terminal. Therefore, the card holder contains an electronic card that can communicate wirelessly with the electronic terminal, referred to in this application as a "find card." The shape and structure of this card are similar to an ID card, bus card, or bank card.

[0045] The purpose of equipping the electronic terminal with a card holder is to establish a communication connection between the electronic terminal and the locator card within the card holder. When the locator card is separated from the electronic terminal, its location can be displayed on the electronic terminal, helping the user quickly and accurately find the card holder with the locator card. The card holder can also be placed in a vehicle to locate the car's parking spot. Additionally, the locator card needs to be thin, have good toughness, and be easy to manufacture to reduce production costs.

[0046] Figure 1 An embodiment of the card holder of this application is shown, including a first card holder layer 3 and a second card holder layer 4, which are bonded together to form an internal bonding space. A magnet 2 and a search card 1 are disposed within this bonding space. The shape, number, and position of the magnets 2 within the card holder are adapted to a magnetic electronic terminal or the back cover of the electronic terminal. The search card 1 is provided with a defining hole 113 corresponding to the shape and position of the magnets 2, and the magnets 1 are fixedly disposed within the defining hole. Specifically, as shown... Figure 1As shown, magnet 2 consists of two magnets, one above the other. The upper magnet is a ring shape, and the lower magnet is a strip shape. They can also be combined... Figure 12 Further, the difference lies in Figure 1 Magnet 2 is located on the outside of the card locator. Figure 12 The magnet is located inside the card.

[0047] Specifically, the materials of the first card layer 3 and the second card layer 4 can be flexible fabric, synthetic fiber, leather, etc. The two are mainly bonded together by adhesive bonding. For example, the magnet 2 and the finder card 1 are first glued to the inner surface of the second card layer 4, and then the first card layer 3 is placed on top, bonding the inner surfaces of the second card layer 4 and the first card layer 3 together. Further pressing can be applied to ensure a tight bond and keep the magnet 2 and finder card 1 fixed in place. Alternatively, the magnet 2 and finder card 1 can be first glued to the inner surface of the first card layer 3, and then the second card layer 4 can be placed on top.

[0048] Figure 1 The magnet 2 in the design comprises two magnets: a first magnet located at the top, which is arc-shaped, and a second magnet located at the bottom, which is elongated. This shape and arrangement of the magnets are primarily adapted for magnetically attaching to electronic terminals or the back cover of electronic terminals, as this type of magnet is used to magnetically attach to the casing or back cover of the electronic terminal. For example, the electrical design of wireless charging for Apple mobile phones requires a magnet mounting structure similar to that described in this application. The magnets can also be rectangular, elliptical, or comprise multiple magnets of different shapes, and are not limited to this design. Figure 1 The construction method in it.

[0049] Correspondingly, Figure 1 The limiting hole 113 on the search card 1 is a through hole that runs through both sides of the search card. Therefore, the magnet 2 can be fixed inside the limiting hole. The shape and position of the limiting hole 113 on the search card are adapted to the corresponding magnet.

[0050] Therefore, the magnet in the card holder allows it to attract to the back of the electronic terminal, or to the back of the terminal's back cover. This is because the back cover has a metal element positioned corresponding to the magnet, which generates a magnetic attraction between itself and the magnet. Furthermore, since the card finder can also communicate wirelessly with the electronic terminal, it can be located and searched even after the card holder has detached from the terminal, ensuring accurate and timely retrieval.

[0051] Furthermore, in Figure 1 On this basis, Figure 2 Further details show that a support frame 42 is provided on the outside of the second card holder layer 4 to support the electronic terminal. This support frame 42 is preferably a foldable bracket, which can be unfolded when needed. Figure 2As shown, when it needs to be folded up, it can be placed close to the outer surface of the second card holder layer 4. Combined with... Figure 3 A card insertion opening 41 is provided on the outside of the second card layer 4. This opening corresponds to the opening of the card receiving cavity, through which cards, such as ID cards and bus cards, can be inserted and accommodated.

[0052] Figure 1 and Figure 2 In the shown embodiment, the search card 1 and the magnet 2 are set separately, but they can also be combined together, that is, the magnet 2 is built into the inside of the search card 1. Therefore, the limiting hole 113 is no longer set on the search card 1. Figure 4 The search card 1 with this construction is shown, and therefore the search card 1 has a built-in magnet.

[0053] Furthermore, a rigid material sheet is embedded within the second card holder layer 4 to support the card holder. This rigid material sheet can be a metal sheet, a plastic sheet, or a synthetic material sheet, etc., and is embedded inside the second card holder layer 4. Its shape and size are adapted to the second card holder layer 4, thus the second card holder layer includes an internal skeleton and is therefore supported. Figure 5 and Figure 6 Two types of manganese steel sheets, each 0.3 mm thick, are shown, used as a second card layer containing a rigid material sheet.

[0054] The following provides a more detailed explanation of how to find the card. Figure 7 An exploded view of an embodiment of the card finder in this application's card package is shown, including: a first card face 11 and a second card face 12, the first card face 11 and the second card face 12 being tightly joined together. Figure 7 The displayed content is for illustrative purposes only; the two card sides are separate, but in the actual product they are joined together. Circuit board 13 and battery (…). Figure 7 (Not shown in the image, but can be positioned behind the circuit board 13 shown in the figure), both are sandwiched between the first card surface 11 and the second card surface 12. The circuit board 13 has a chip for communicating with an adapted electronic terminal, such as Bluetooth or WiFi communication. The battery is electrically connected to the circuit board 13, and the circuit board has an induction coil, which enables wireless charging of the battery. The first card surface 11 and the second card surface 12 can be made of PVC material.

[0055] Figure 7In the illustrated embodiment, the circuit board and battery are sandwiched between the first card surface 11 and the second card surface 12, thus embedding the circuit board and battery within these two card surfaces. The first card surface 11 and the second card surface 12 are tightly joined using methods such as snap-fitting, bonding, and bonding with polymer cold-pressing adhesive technology. Any remaining gaps between the first card surface 11 and the second card surface 12, besides the circuit board and battery, can be filled and / or bonded using soft materials, liquid adhesives (which harden after drying), polymer adhesives, etc., to ensure that the space between the first card surface 11 and the second card surface 12 is completely filled, avoiding any empty areas and ensuring a smooth and even interior.

[0056] Figure 7 The first card face 11 and the second card face 12 in the image are not displayed. Figure 1 The limiting hole 113 on card 1 is located because after the two card surfaces are bonded to the circuit board and battery, the limiting hole can be machined between the two card surfaces using CNC (Computerized Numerical Control). The result is as follows: Figure 8 As shown, it includes a defining hole 113 that penetrates the first card surface 11 and the second card surface 12. Of course, Figure 7 The first card surface 11 and the second card surface 12 can also be card surfaces without a limiting hole. In this case, the magnet can be placed inside the two card surfaces.

[0057] Additionally, for ease of explanation, in Figure 7 In the orientation shown, the first card face 11 is located on the front side, and the second card face 12 is located on the back side. The front of the first card face 11 may also have markings printed on it, such as... Figure 8 As shown, the markings include switch indicator 111, light indicator 112, etc., used for human-machine interface operation and status display. The markings on the first card face are also for correspondence with the circuit board, because the circuit board has a switch and indicator light facing the first card face, which corresponds to switch indicator 111 and light indicator 112. If the switch and indicator light on the circuit board face the second card face, then these markings are set on the second card face. Therefore, there is no restriction on whether the markings are placed on the first or second card face; "first" and "second" are only used to distinguish between the two card faces.

[0058] Furthermore, circuit board 13 is an integrated flexible circuit board. For example... Figure 9As shown, circuit board 13 has multiple looped lines 131 printed on it for wireless charging of the battery. The chip includes a Bluetooth chip and / or a WiFi chip 132, which can integrate Bluetooth or WiFi communication alone, or both, for wireless communication with a compatible electronic terminal. A communication antenna 1321 electrically connected to chip 132 is printed on the circuit board. Chip 132 also has control functions, electrically connected to buttons 133, a speaker 135, and an indicator light 134, controlling the human-machine interface functions of these components.

[0059] A button 133 is connected to the circuit board 13. A switch symbol 111 is printed on the first card surface 11, and the position of the switch symbol 111 on the first card surface corresponds to the position of the button 133 on the circuit board 13. An indicator light 134 (such as a light-emitting diode) is connected to the circuit board 13. An indicator light symbol 112 is printed on the first card surface 11, and the position of the indicator light 112 on the first card surface 11 corresponds to the position of the indicator light 134 on the circuit board 13. A speaker 135 is connected to the circuit board 13. The speaker 135 has a planar structure, and therefore has a small thickness.

[0060] like Figure 9 As shown, the circuit board 13 includes a first circuit area 1301 and a second circuit area 1302, with a connecting area 1303 between them. This connecting area 1303 connects the first circuit area 1301 and the second circuit area 1302 into a single circuit board. This partitioning of the circuit board 13 is primarily for structural adaptation to magnets (such as...). Figure 12 The shape, structure, and installation position (as shown) are designed to adapt to the electrical characteristics of the electronic terminal. It can be seen that the first circuit area 1301 is circular, with multiple loops of circuitry 131 arranged within it; the second circuit area 1302 is generally rectangular, with a triangle extending from the upper right corner. The aforementioned buttons 133, indicator lights 134, speaker 135, and Bluetooth and / or WiFi chip 132 are all located in the second circuit area 1302.

[0061] Furthermore, an opening 1304 is also provided in the second circuit area 1302, the shape and position of which are adapted to accommodate a magnet installed within it. Figure 12 The second magnet 22 in the middle, Figure 13The second magnet 22 is defined within the second limiting part 1422. Furthermore, the opening 1304 is a continuously closed opening around its perimeter. The circuit board around the opening 1304 is connected as a whole. In particular, the connection channel 1305 above the opening 1304 has a relatively small space, but the existence of the connection channel 1305 is beneficial for the second circuit area 1302 to form a connected circuit board on the left and right sides of the opening 1304. This allows both sides to be grounded together, and there is no disconnection at the top of the second circuit area 1302 due to the opening 1304. This design helps to reduce the interference of the magnetic field generated by the magnet defined inside the opening 1304 on the Bluetooth signal and / or WiFi signal, because the Bluetooth chip and / or WiFi chip 132 and the communication antenna 1321 are provided on the second circuit area 1302 near the opening 1304.

[0062] like Figure 10 As shown, this is another embodiment of circuit board 23. Compared with circuit board 13, the multi-ring circuit 231, Bluetooth and / or WiFi chip 232, button 233, indicator light 234, speaker 235, and first circuit area 2301, second circuit area 2302, connection area 2303, and communication antenna 2321 correspond to... Figure 9 The multi-ring circuit 131, Bluetooth chip and / or WiFi chip 132, button 133, indicator light 134, speaker 135, first circuit area 1301, second circuit area 1302, connection area 1303, and communication antenna 1321 on the circuit board 13 have the same shape, layout structure and function, which will not be described in detail here.

[0063] The main difference between circuit board 23 and circuit board 13 is that its opening 2304 is an empty opening. The second circuit areas on the left and right sides above this opening are isolated and disconnected. That is, the upper part of opening 2304 is not connected but disconnected and isolated. In other words, there is no circuit above opening 2304. Figure 9 The connection channel 1305 is shown. Therefore, this structural design does not significantly reduce the interference of the magnetic field generated by the magnet on Bluetooth or Wi-Fi signals. Figure 9 The illustrated embodiment is better, but it can also achieve short-range wireless communication via Bluetooth or Wi-Fi.

[0064] exist Figure 9 The first circuit area 1301 also includes positive and negative electrodes 1306 for connecting the positive and negative terminals of the rechargeable battery, allowing the battery to be charged via a multi-turn loop circuit 131. Correspondingly, in... Figure 10 The first circuit area 2301 is also provided with positive and negative electrodes 2306.

[0065] above Figure 9 and Figure 10The explanation mainly focuses on the circuit board's structure and layout, without detailing the components and electrical connections. The following section will combine... Figure 11 Please provide a detailed explanation.

[0066] exist Figure 11 In the circuit, a multi-turn loop circuit 131 is electrically connected to the input terminal of the battery charging circuit 136. The loop circuit 131 is used to induce electromagnetic energy, and the battery charging circuit 136 can convert the electromagnetic energy into a charging current and output it to the battery for charging. The output terminal of the battery charging circuit 136 is connected to the positive terminal of the rechargeable battery, and the negative terminal of the battery is grounded. A battery protection chip 137 is connected in parallel across the positive and negative terminals of the battery for safety protection and monitoring of battery charging and discharging.

[0067] The positive terminal of the battery is also connected to the input terminal of the linear regulated power supply 138, which is used to regulate or transform the output voltage of the battery before output. The output terminal of the linear regulated power supply 138 is connected to the positive terminals of the Bluetooth and / or WiFi chip 132, the triaxial sensor 139, and the light-emitting diodes 134 (there are 3 in the figure, corresponding to the three different light-emitting colors of red, green and blue).

[0068] The triaxial sensor 139 can be used to sense the motion state of the search card, perform motion analysis and positioning measurement on the search card, and realize the positioning function. The Bluetooth and / or WiFi chip 132 has communication and control functions, and transmits and receives wireless communication signals through an antenna, thereby communicating wirelessly with the adapted electronic terminal.

[0069] The Bluetooth chip and / or WiFi chip 132 are also electrically connected to the button 133, buzzer 135, and indicator light 134 (shown as an LED). The button 133 allows for powering on / off operation of the search card, as well as other operations. The buzzer 135 emits a prompt sound, and the indicator light 134 displays different operating states, and may include red, green, and blue LEDs, such as charging status, low voltage indication, etc.

[0070] Furthermore, in Figure 7 It also includes a bracket 14, which is also sandwiched between the first card surface 11 and the second card surface 12, for limiting the circuit board 13 and the magnet (including limiting the magnet inside the card or limiting the magnet outside the card).

[0071] Specifically, such as Figure 12As shown, the bracket 14 includes a circuit board receiving portion 141 and a magnet limiting portion 142. The circuit board receiving portion 141 is used to receive the circuit board 13, and its external structure is adapted to the external structure of the circuit board 13. The magnet limiting portion 142 is used to limit the magnet. The position of the magnet limiting portion 142 corresponds to the position of the magnetic metal body on the back shell of the electronic terminal, and the structure of the magnet limiting portion 142 also corresponds to the structure of the magnetic metal body on the back shell of the electronic terminal. In this application, the position and structure of the magnet sandwiched in the first card surface and the second card surface correspond to the metal body, thereby ensuring that the two can be effectively magnetically attracted. The position and structure of the metal body on the back of the electronic terminal or the metal body on the back shell of the electronic terminal are determined by the electrical characteristics of the internal circuit of the electronic terminal.

[0072] Figure 12 The device includes a first magnet 21 and a second magnet 22. The first magnet 21 is a ring-shaped magnet with a notch, or it can be a ring structure composed of multiple small magnet blocks. The second magnet 22 is a strip-shaped magnet. Both are respectively positioned and mounted on their corresponding magnet limiting parts 142. The magnets are common magnets or other magnetic materials, used to attract metal objects such as iron or steel blocks.

[0073] Furthermore, such as Figure 12 and Figure 13 As shown, the bracket 14 also includes an edge portion 143, which is disposed around the circuit board receiving portion 141 and the magnet limiting portion 142, and adapts to the edge structure of the first card face and the second card face. It can be seen that the edge portion forms a rectangle, which adapts to the edge structure of the first and second card faces, since the edges of the first and second card faces are also rectangles. Specifically, the adaptation relationship includes the edge portion having the same shape and size as the first and second card faces. This allows the bracket edge to be fastened or bonded simply by aligning with the edges of the first and second card faces, while also ensuring alignment between the internal structure of the bracket and the circuit board, magnet, etc. Alternatively, as a variation, the adaptation relationship also includes the edge portion having a proportionally smaller shape and size than the first and second card faces, as long as the geometric center of the bracket coincides with the geometric center of the first and second card faces. The excess edge portion of the first and second card faces is joined between the edges of the first and second card faces, effectively encapsulating the bracket within the cavity enclosed by the first and second card faces.

[0074] Since the bracket 14 is used to limit the circuit board 13 and the magnet, when the bracket 14 is accurately positioned between the two card surfaces, the circuit board 13 and the magnet will also be accurately positioned accordingly. The bracket 14 has an edge portion, which makes accurate positioning of the bracket 14 convenient and efficient, because the outer edges of the bracket and the two card surfaces are completely aligned. As long as the three are perfectly aligned vertically, the bracket can be accurately positioned, reducing and avoiding the need for separate processes for accurate positioning of the bracket.

[0075] The circuit board receiving portion 141 includes a first receiving portion 1411, and the magnet limiting portion 142 includes a first limiting portion 1421. The periphery of the first receiving portion 1411 corresponds to the first limiting portion 1421. Figure 9 The circuit board 13 includes a first circuit area 1301 and a first receiving portion 1411 for receiving the first circuit area 1301. Multiple ring lines 131 are printed on the first circuit area 1301 for wireless charging.

[0076] Specifically, the first limiting part 1421 is annular, used to limit multiple magnetic blocks arranged in a ring or to limit a corresponding magnetic ring. Figure 12 The first magnet 21 in the middle.

[0077] The circuit board receiving portion 141 further includes a second receiving portion 1412, and the magnet limiting portion 142 includes a second limiting portion 1422. The periphery of the second limiting portion 1422 corresponds to the second receiving portion 1412. The circuit board 13 includes a second circuit area 1302, and the second receiving portion 1412 is used to receive the second circuit area 1302. A chip is soldered on the second circuit area 1302. It can be seen that the first receiving portion 1411 and the second receiving portion 1412 are connected to each other, and the corresponding connection part is the receiving connection portion 1413. This allows the corresponding receiving connection area 1303 to connect the first circuit area 1301 and the second circuit area 1302.

[0078] Specifically, the second limiting part 1422 is strip-shaped and is used to define a corresponding bar magnet or a combination of multiple magnet blocks. It can be seen that the second limiting part 1422 is located below the first limiting part 1421. Furthermore, the relationship between the shape, size, and position of the first limiting part 1421 and the second limiting part 1422 is merely illustrative and not limiting, as long as it can be matched with the design requirements of the adapted electronic terminal or the structural design of the metal body of the electronic terminal's back cover. The shape, size, and position of the first limiting part 1421 and the second limiting part 1422 are related to... Figure 1The magnet limiting part 142 of the bracket 14 corresponds to the limiting hole 133 of the card. That is, when the magnet is positioned outside the card, the magnet limiting part 142 of the bracket 14 corresponds precisely to the opening position and shape of the limiting hole 133. It can be seen that the first limiting part 1421 and the second limiting part 1422 are two independent parts, each corresponding to a specific limiting hole. Figure 12 There are two independent first magnets 21 and second magnets 22.

[0079] Figure 13 The first receiving portion 1411, the second receiving portion 1412, and the receiving connecting portion 1413 shown are hollow structures that are open at both ends. However, they are not limited to this hollow structure; they can also be solid planar structures or recessed grid structures that are recessed from front to back. That is to say, the first receiving portion 1411, the second receiving portion 1412, and the receiving connecting portion 1413 have recessed bottom surfaces inside, which can accommodate and support the circuit board. Another implementation is to first inject liquid adhesive or soft adhesive into the hollow first receiving portion 1411, the second receiving portion 1412, and the receiving connecting portion 1413, and then place the circuit board in. After these materials solidify or harden, they will bond with the three receiving portions as one, and at the same time, fix the circuit board to these receiving portions. In addition, these liquid adhesive, soft adhesive, polymer materials, etc., can also be used to fill gaps, so that the various components on the circuit board are isolated from air, preventing oxidation, and also ensuring the flatness and fullness of the filling material inside the two card surfaces.

[0080] Figure 14 Another embodiment of the bracket 24 is shown, which is adapted to correspond with the circuit board 23. Figure 12 and Figure 13 Compared to the stent 14, the main difference is that Figure 14 The bracket 24 in the design does not include the edge portion 143 and the first limiting portion 1421. The first magnet is defined by the periphery of the first receiving portion 2411, thus achieving a simplified design. While this design structure is advantageous for saving materials, it lacks... Figure 13 The edge portion 143 is not suitable for directly aligning the bracket 24 with the periphery of the first and second card surfaces. Instead, the bracket 24 needs to be accurately calibrated and positioned to ensure it accurately defines the position of the magnet and accommodates the circuit board. The bracket 24 includes a first accommodating portion 2411, a second accommodating portion 2412, an accommodating connecting portion 2413, and a second limiting portion 2422, which respectively correspond to... Figure 13 The first receiving portion 1411, the second receiving portion 1412, the receiving connecting portion 1413, and the second limiting portion 1422 in the middle support 14 have the same structure and function, and will not be described in detail here.

[0081] Figure 14The first receiving portion 2411, the second receiving portion 2412, and the receiving connecting portion 2413 in the bracket 24 can accommodate Figure 9 or Figure 10 The circuit boards 13 or 23 shown will not be described again here.

[0082] and Figure 7 The embodiments shown are similar. Figure 15 This diagram shows an exploded view of another embodiment of the card locator in this application, wherein circuit board 23 and bracket 24 respectively correspond to... Figure 10 and Figure 14 In the embodiment, the first card surface 21 and the second card surface 22 are... Figure 7 The first card face 11 and the second card face 12 have the same structure and function, which will not be described in detail here.

[0083] Figure 7 and Figure 15 In the illustrated embodiment, the first card surface, the second card surface, and the support are all made of PVC, PC, PET, RPVC, or RPET materials. The support, circuit board, battery, and magnet are pressed together between the first and second card surfaces using a cold pressing process. This method allows for the manufacture of search cards with a thickness of less than or equal to 2 mm.

[0084] It is evident that the finder card is relatively thin and has a certain degree of flexibility, allowing it to be bent to a certain extent. This makes it easy to embed in a card holder, which typically contains important documents such as bank cards and ID cards. If the card holder is forgotten or lost, the built-in finder card can be used to locate it quickly and easily.

[0085] Therefore, this utility model discloses a card holder adapted to an electronic terminal, comprising: a first card holder layer and a second card holder layer, which are bonded together to form an internal bonding space. A magnet and a search card are disposed within this bonding space. The search card contains a sealed circuit. The shape and position of the magnet within the card holder are adapted to a magnetically attached electronic terminal or the back cover of the electronic terminal. The search card has a defining hole corresponding to the shape and position of the magnet, and the magnet is fixedly disposed within the defining hole. The search card is used for communication with the adapted electronic terminal. This card holder is lightweight, thin, and durable. The internal search card is tough and waterproof, enhancing the user experience.

[0086] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
