Description

Technical Field

[0001] This utility model relates to an electronic device, and more particularly to a mobile phone add-on module. Background Technology

[0002] As smartphones become increasingly sophisticated, users' demands for phone performance and application scenarios are also constantly rising. While modern smartphones have made significant progress in processing power, storage capacity, and display quality, the high integration of numerous functions within a small device limits the potential of many capabilities. Furthermore, there is a need for functional expansion for phones with different configurations, particularly in communication, photography, and specific application scenarios. Therefore, using external devices to extend phone functionality is a convenient way to expand a phone's capabilities.

[0003] However, traditional methods of connecting mobile phone accessories often present certain inconveniences. For example, making the connection between the accessory and the phone both convenient and practical has become a bottleneck in technological development. To address this challenge, Apple introduced the MagSafe magnetic solution on its products. This solution uses a ring-shaped strong magnet and a positioning magnet on the back of the mobile device to create a relatively secure magnetic connection between the accessory and the phone, successfully solving the problem of ease of connection and subsequent use. This solution effectively improves the user experience, leading to the widespread adoption of products such as magnetic power banks and magnetic accessories. These devices offer high efficiency and ease of use, meeting the basic functional expansion needs of most users.

[0004] However, with the increasing demand for more powerful add-on functions, existing magnetic solutions have revealed some shortcomings. While magnetic technology provides a convenient connection method, it only solves the physical connection problem between the add-on device and the phone. Although it can achieve electrical conduction through methods such as electromagnetic coils, the power is very low, and this electrical conduction is only for power supply, not data transmission. Correspondingly, existing solutions cannot meet the needs of add-on devices that require high-performance expansion. In addition, as an additional accessory for mobile phones, convenience and practicality are very important since the usage scenarios are mostly tied to the phone, and there are many considerations regarding size and weight. Magnetic attraction can only solve some problems and cannot meet all needs. For example, for satellite phone modules that require high-frequency communication, or camera modules that require higher image quality, a magnetic structure alone cannot meet their needs in terms of communication and power transmission. Furthermore, some add-on devices may require direct wired communication with the phone, and a simple magnetic attraction method obviously cannot effectively solve this problem.

[0005] Therefore, designing a reasonable external electronic module structure that can meet the needs of complex functional expansion while finding the optimal balance in terms of size, weight, and ease of operation has become a major technical challenge in the industry. Especially in the face of rapid technological iteration and higher performance demands, designing a module structure that is highly compatible with mobile phone systems remains an important direction for technological development in the industry.

[0006] In recent years, satellite communication technology has developed rapidly, leading to a growing demand for satellite phone functionality. Many users hope to communicate directly with satellite devices via their mobile phones for use in remote areas. Furthermore, with the widespread adoption of video, users' demand for high-definition photography and videography has increased significantly, as has the need for high-quality image processing capabilities. Therefore, smartphone add-on modules not only need to support efficient communication but also require stronger image processing capabilities. These demands have further driven the development of add-on devices, making the design and application of related add-on modules a crucial direction for current technological research and development.

[0064] To illustrate the technical content, structural features, objectives, and effects of this utility model in detail, the following description, in conjunction with the embodiments and accompanying drawings, provides a comprehensive explanation. It should be noted that the technical solutions described in detail below, along with the embodiments described with reference to the accompanying drawings, are exemplary and intended to explain this utility model, and should not be construed as limiting it.

[0065] like Figure 1 , 2 As shown, a mobile phone add-on module is designed as two separate parts in order to minimize its size: the host end 1 and the device end 2.

[0066] The host unit 1 includes a main body 10, which can be designed in any shape, but a common and preferred design is a square or round flat plate to facilitate attachment to the back of the phone 3, minimizing user interference and improving grip. Regardless of the shape, the main body 10 must have a phone-attaching surface 101, and a magnetic ring is provided inside the main body 10 corresponding to the phone-attaching surface 101. A magnetic area 102 is provided on the phone-attaching surface 101 corresponding to the magnetic ring. Thus, the main body 10 can be attached to the back of the phone 3 via the attaching surface 101, and a magnetic attraction is formed between the main body 10 and the phone 3 (which has MagSafe functionality or a phone with a MagSafe-like casing) via the magnetic ring. Inside the main body 10 is a main control board and a battery electrically connected to the main control board. The main control board is responsible for implementing all the main functions and controls of the external phone module, while the battery primarily powers the entire external phone module, preventing the phone 3 from consuming its own power.

[0067] Since the device end 2 and the host end 1 are designed separately, the motherboard inside the host end 1 is electrically connected to a first cable 13. This first cable 13 extends from the right end of the main body 10, near the phone-fitting surface 101 of the main body 10, after passing through the first telescopic adjustment mechanism, to the device end 2. This design of the first cable 13 is to minimize its impact on use. The first cable 13, extending from the side of the main body 10 near the phone-fitting surface 101, can be routed as close as possible to the surface of the phone. The overall choice of the first cable 13 starting from the right end of the main body 10 is to minimize the impact on the large camera module that is usually located on the left or in the middle of existing phones. The first cable 13 can be extended from the right end of the entire main body 10 or from the upper right end of the main body 10, as shown in the figure, which shows the option of extending from the upper right end of the main body 10.

[0068] Furthermore, the first cable 13 of the motherboard electrical connection device end 2 can be selected to be a signal cable that does not require power supply (such as when the device end 2 is only an antenna or other device that does not require additional power supply), or a general USB data cable that has both power supply and signal transmission capabilities, depending on whether power supply is required.

[0069] Furthermore, the first cable 13 can be adjusted in length by the first telescopic adjustment mechanism, thereby controlling the distance between the device end 2 and the host end 1. In the simplest design, the first cable 13 is retracted into the main body 10 under the linkage of the first telescopic adjustment mechanism, and can be pulled out of the main body by external force. In this structure, the first telescopic adjustment mechanism only needs to play a retraction function, without having to take into account both retraction and deployment, which is simpler. Thus, when the entire product is in use, the main body 1 is magnetically attached to the mobile phone 3, and the device end 2 is fixed to the end of the mobile phone 3 after being pulled out.

[0070] To ensure good data transmission between the product and the mobile phone, the motherboard is also electrically connected to a second cable 14. The second cable 14 is led out from the side of the mobile phone contact surface 101 of the main body 10, and its head is provided with a data terminal 15.

[0071] The second cable 14 is also designed for a close fit, so it extends along one side of the phone's bonding surface 101 to adhere as closely as possible to the phone's surface. The position from which it exits the main body 10 can be chosen as needed. As shown in the diagram, the simplest option is to extend it from the bottom center, directly corresponding to the data interface at the bottom of the phone, minimizing the relative length of the second cable 14. Alternatively, it can extend from the side, avoiding some components at the bottom of the phone, and connect to the data interface in the middle of the phone via an L-shaped segment at the bottom.

[0072] Unlike the host unit 1, which is designed to fit as closely as possible to the back of the phone, the core design of the device unit 2 is to support the extended functions while ensuring it can be fixed to the end (usually the top) of the phone. The device unit 2 also includes a housing 21, on which are provided the external functional mechanisms that need to be added (such as additional camera modules, communication modules, etc.). In typical usage scenarios, the device unit 2 is fixedly connected to the edge of the phone (such as the top of the phone) through a fixing mechanism 22.

[0073] The first cable 13 from the host end 1 extends into the housing 21 of the device end 2 and is electrically connected to the external functional mechanism. The first cable 13 connecting the host end 1 to the device end 2 can be configured according to the needs of the device end. If the device end only needs signal transmission, a signal cable can be used. If the function of the device end 2 requires both data and power, then the simplest way to achieve this is to use a mature USB data cable.

[0074] The beneficial effects of this utility model are as follows: It provides a mobile phone add-on module that expands mobile phone functionality. The module consists of two separable main units and a device unit. The main unit can be magnetically attached to the mobile phone to form a connection, while the device unit can be secured to the edge of the phone for operation. Furthermore, the structure, shape, and position of the first cable connecting the main unit and the device unit, and the second cable connecting the main unit to the mobile phone, have been optimized for practical application. This allows the entire product to be easily assembled and stored when not in use, and to be separated and fit snugly with the phone when in use. This minimizes the inconvenience caused to the user after attaching this patented module to the mobile phone. By connecting this patented product, the mobile phone not only gains enhanced or expanded capabilities but also maintains a consistent feel and grip with the original mobile phone, even achieving a seamless integration.

[0075] Example 1

[0076] To enable device 2 to better connect and be fixed to the edge of the phone, while minimizing intrusion into the phone screen area (especially the top screen area, as there are many key navigation buttons in applications such as live streaming).

[0077] like Figure 2 , 3 As shown, a mobile phone frame bonding surface is provided on the outer casing 21 of the device end 2, and a protrusion 210 is provided on the front side of the mobile phone screen corresponding to the mobile phone frame bonding surface. In this embodiment, the fixing mechanism 22 is provided on both sides of the mobile phone screen.

[0078] Thus, the entire device 2 corresponds to the screen of the mobile phone 3. The whole is mainly connected by the left and right fixed fixing mechanisms 22, and with the front and rear protrusions 210 and the limiting of the contact surface of the mobile phone frame, the protrusions 210, especially the protrusions 210 on the side corresponding to the screen of the mobile phone 3, can achieve the overall 3-point (actually 4-point) fixation with a very small height, thereby achieving the purpose of stably fixing the entire device 2 while minimizing intrusion into the screen of the mobile phone 3.

[0079] In the structure of the above embodiment 1, the fixing mechanism 22 can specifically adopt a gripper structure.

[0080] Specifically, the fixing mechanism includes at least two grippers respectively disposed at both ends of the phone frame bonding surface of the outer casing (corresponding to the left and right sides of the phone screen 3). The grippers are movably connected to the outer casing 21, and an elastic reset element (such as a tension spring) is provided between the outer casing 21 and the grippers. Under the action of external force, the grippers can move away from the outer casing and open. After the external force disappears, the grippers move back towards the outer casing 21 under the action of the elastic reset element, thereby achieving a horizontal clamping in the left and right direction. This structure, together with the front protrusion 210, minimizes the intrusion of the phone screen 3 while ensuring the application requirements of the device end 2 being fixedly connected to the phone.

[0081] Example 2

[0082] This embodiment provides a fixing method different from that of Embodiment 1, which can also achieve better connection and fixation of the device 2 to the edge of the mobile phone, while minimizing encroachment on the mobile phone screen area.

[0083] like Figure 4-6 As shown, the outer shell 21 of the device 2 also has a mobile phone frame bonding surface, and the mobile phone frame bonding surface only has a protrusion 210 on the front side of the screen of the mobile phone 3; the fixing mechanism 22 includes a positioning plate disposed on the rear side of the mobile phone frame bonding surface of the outer shell 21, the positioning plate is higher than the protrusion, and a camera clearance slot 301 is opened corresponding to the functional module 301 of the mobile phone.

[0084] Because the rear positioning plate is higher than the front protrusion, the entire device end 2 will be resisted when tilted backward. To strengthen the connection, a suction cup can be installed on the positioning plate, which will also adhere more firmly under the leverage. Alternatively, the positioning plate can adopt a structure with a movable connection such as a gripper and an elastic reset component (such as a tension spring) to achieve front and rear clamping.

[0085] It should be noted that the above embodiments 1 and 2 only provide two ideas for a more stable connection between the device and the mobile phone. In practice, a stable connection can also be achieved through methods such as magnetic attraction or designing suction cups on the contact surface of the mobile phone frame, which will not be elaborated here.

[0086] Example 3

[0087] In this embodiment, the second cable 14 is also designed as a retractable structure, with a design that maximizes fit. Specifically, after passing through the second telescopic adjustment mechanism, the second cable 14 is brought close to the phone-fitting surface 101 of the main body 10 at the host end 1 and extends out from the lower part of the main body 10. This structure ensures that the second cable 14 remains attached to the phone surface during use, maximizing both aesthetics and ease of use.

[0088] Similarly, the simplest design employs a second cable 14 that can be retracted into the main body under the linkage of the second telescopic adjustment mechanism, and extended out of the main body under external force. This allows the second telescopic adjustment mechanism to only perform a retraction function, without having to handle both retraction and extension, making it much simpler. Therefore, when the entire product is not in use, the main unit 1 and the device unit 2 are attached, with all the first cables 13 and second cables 14 retracted within the main body 10 of the main unit 1, resulting in a uniform and aesthetically pleasing appearance. When needed, the device unit 2 is pulled open, triggering the extension of the first cable 13, and then the second cable 14 is pulled open and connected to the data interface of the mobile phone 3 for use.

[0089] The first and second telescopic adjustment mechanisms mentioned in this patent can be implemented using methods such as purely mechanical structures, springs, or ring-shaped springs. Two application examples of purely mechanical structures and spring structures are given below:

[0090] Example 1

[0091] See Figure 7 , 8 As shown, the first telescopic adjustment mechanism includes a first slide rail 161, a first slider and a first groove 163. The first slider 162 is limited to slide in the first slide rail 161. The main body 10 has a first groove 163 corresponding to the sliding range of the first slider 162, and the first slider 162 protrudes out of the first groove 163. The first cable 13 is led out by passing around the first slider 162.

[0092] Therefore, when the first slider 162 slides along the first slide rail 161, the first cable 13, which is wound around it, will fold, thereby adjusting the length of the portion of the first cable 13 extending outside the main body 10. When in use on the device end 2, the first cable 13 outside the main body 10 can be gently pulled out, or preferably pushed upwards on the first slider 162, to extend it, separating the device end 2 from the host end 1 and fixing it to the upper part of the phone. After use, the first slider 162 can be pushed downwards to fold the first cable 13, retracting the device end 2 back to the host end 1.

[0093] The second telescopic adjustment mechanism also adopts the same manual storage structure, which includes a second slide rail 171, a second slider 172 and a second slide groove 173. The second slider 172 is limited to slide in the second slide rail 171. The main body 10 has a second slide groove 173 corresponding to the sliding range of the second slider 172, and the second slider 172 protrudes out of the second slide groove 173. The second cable 14 is led out after passing around the second slider 172.

[0094] Therefore, when the second slider 172 slides along the second slide rail 171, the second cable 14, which is wound around it, will fold in conjunction with the second slider 171, thereby adjusting the length of the portion of the second cable 14 extending outside the main body 10. During use, the second cable 14 can be stretched by pulling it directly, or preferably by pushing the second slider 172 downwards, allowing it to extend and connect to the bottom of the phone. After use, the second cable 14 can be folded back into the main body 10 by pushing the second slider 172 in the opposite direction.

[0095] Example 2

[0096] Unlike Example 1, this presents a structure that can automatically retract. See [link / reference] Figure 9 , 10 As shown, this solution adds a return spring to Example 1, which allows the stretched first slider to return to its original position under the action of the return spring. Correspondingly, the first groove 163 and the second groove 173 on the main body 10 can be eliminated, and the first slider 162 and the second slider 172 do not need to protrude from the main body. This makes the overall appearance more aesthetically pleasing. Of course, if accurate recycling is required, retaining the aforementioned first groove 163, second groove 173, and protruding first slider 162 and second slider 172 is also possible. This will not be elaborated upon here.

[0097] The core structure of the first telescopic adjustment mechanism includes a first slide rail 161, a first slider 162, and a first return spring 164. The first slider 162 is limited to sliding within the first slide rail 161 and connected to the first return spring 164. The first cable 13 passes around the first slider 162 and is then led out. When the first cable 13 is stretched by an external force, the first slider 162 slides along the first slide rail 162, simultaneously stretching the first return spring 164 and storing energy in it. When the stretching force on the first cable 13 disappears, the first slider 162 slides along the first slide rail 162 under the action of the first return spring 164, retracting the first cable 13.

[0098] Similarly, the core structure of the second telescopic adjustment mechanism includes a second slide rail 171, a second slider 172, and a second return spring 174. The second slider 172 is limited to slide in the second slide rail 171 and is connected to the second return spring 174. The second cable 14 passes around the second slider and is led out at 172. When the external force of the second cable 14 is removed, the second slider 172 will slide along the second slide rail 172 under the action of the second return spring 174, and the second cable 14 will be retracted.

[0099] It should be noted that the second cable 14 in this embodiment is only an example. In practice, it can be designed not to be stretchable, but to have a fixed length and be foldable for storage. For example, a receiving cavity can be provided in the middle of the phone-fitting surface 101 of the main body 10, and the fixed-length second cable 14 can be led out from the bottom of the main body 10 near the phone-fitting surface 101, with its main part extending out of the main body 10 from one side of the phone-fitting surface 11. The overall length is adapted to the largest phone size on the market. Thus, although the second cable 14 may be slightly longer on small-sized phones, the impact on use is minimal, and it ensures compatibility with different phones. For convenient storage, ideally, a concave receiving groove can be provided on the phone-fitting surface 11, so that the second cable 14 can be folded and stored in the receiving groove. This structure requires a relatively longer second cable 14 to adapt to different sized phones, and for some smaller phones, there will be more redundant length, which is not as good as the self-shrinking adaptation scheme of embodiment 3.

[0100] Example 4

[0101] This embodiment focuses on optimizing the connection relationship between the combinable and separable host end 1 and device end 2 when not in use. First, both are provided with corresponding bosses 105 and grooves 205, so that when assembled, the groove 205 of the device end 2 can engage with the host end 105, providing initial positioning. Furthermore, the groove 205 of the device end 2 is the space formed between the bosses 105 that are used to fit and limit the phone frame (i.e., the bottom surface of the groove 205 is the contact surface of the phone frame). Further, a connecting mechanism can be provided on this boss and groove; this connecting mechanism can be one or more of mature technologies such as snap fasteners, magnetic components, and suction cups to achieve a secure connection (usually only one is needed).

[0102] Therefore, when not in use, the two detachable parts of the entire mobile phone add-on module can still be well connected together, instead of relying solely on the first telescopic adjustment mechanism of the first cable 13 for connection. This significantly improves product consistency.

[0103] Example 5

[0104] See Figure 2 , Figure 5The second cable 14 extends from the main body with an extension 141, the head of which is a data terminal 15; the data terminal 15 is double L-shaped; a receiving cavity 103 is provided on the mobile phone bonding surface 101 of the main body 10 corresponding to the extension 141 and the data terminal 15.

[0105] Therefore, when the second cable 14 is recycled, not only can the cable be recycled into the main body 10, but the data terminal 10 can also be recycled into the receiving cavity 103.

[0106] The double L-shaped data terminal 15 not only has significantly improved bending resistance, but also can be well connected and communicated with mobile phones via an inward snap-fit ​​mechanism.

[0107] Example 6

[0108] In this embodiment, the first cable 13 of the host end 1 is further extended from the outer shell 21 of the device end 2 into the outer shell 21 from the other side of the mobile phone bonding surface 101 of the main body 10 away from the host end 1, and electrically connected to the external functional mechanism.

[0109] refer to Figure 12 As shown, during the use of the product, the host end 1 is attached to the back of the mobile phone 3, while the device end 2 is mounted on the end of the mobile phone. The mobile phone attachment surface 101 of the host end 1 corresponds to the other side of the outer shell 21. The first cable 13 is thus led out from the inside of the main body 10 (close to the mobile phone) and introduced from the other side of the outer shell 21 (close to the back of the mobile phone), so that the first cable 13 can fit better against the back of the mobile phone.

[0110] However, this structure inevitably leads to a misalignment when the first cable 13 is positioned on the right side at one end and the other end at the right side at the other end when the device 2 is housed in the host 1, making it prone to breakage. To solve this problem, such as... Figure 11 As shown, the housing of the first cable 13 near the device end is provided with a folding part 131. Preferably, the folding part 131 is Z-shaped, so that it can withstand repeated folding without being easily damaged.

[0111] Example 7

[0112] In this embodiment, a human-computer interaction module is added to the host terminal 1; the human-computer interaction module is connected to the motherboard; the human-computer interaction module includes input devices and display devices;

[0113] The input element includes one or more of the following:

[0114] a. Buttons;

[0115] b. Touchpad;

[0116] The display device includes one or more of the following:

[0117] a. Status indicator lights;

[0118] b. Display screen

[0119] c. Digital picture tube.

[0120] like Figure 12 The image shows a mobile phone add-on module that uses a display screen 16, indicator lights 17, and buttons 18 as a human-computer interaction module. By adding the human-computer interaction module directly to the device, users can control the device directly without the need for external devices, thus enabling the device to be used independently.

[0121] Example 8

[0122] The host unit 1's main body 10 is also provided with a USB interface, which is electrically connected to the motherboard. The electrical connection between the USB interface and the motherboard can be achieved using any of the following methods:

[0123] a. The USB interface is electrically connected to the motherboard separately.

[0124] This connection method is equivalent to the host side 1 having an additional USB interface, through which it can provide power to external devices, power to internal devices, expand to connect new external functional modules, and connect to mobile phones via data cables, in addition to the original functions.

[0125] b. Connect the power cable of the USB interface to the power cable of the second cable.

[0126] In this connection method, the USB interface and the second cable serve the same function of external power supply / internal power supply, while the data lines of the USB interface and the second cable are respectively connected to the motherboard, and the motherboard can control the two to be used separately / switched.

[0127] c. The data cable and power cable of the USB interface are both connected to the data cable and power cable of the second cable. The USB interface is electrically connected to the motherboard and connected to the second cable 14.

[0128] In this connection method, the USB interface is actually another external interface for the second cable, allowing users to connect the external phone module to the phone using an additional, longer cable. This enables the external phone module to be used at greater distances from the phone, fulfilling the need for separate use.

[0129] In addition to the above-mentioned solution, this patent also incorporates many optimized designs, such as:

[0130] Example 9

[0131] The width of the mobile phone bonding surface 101 is between 56mm and 67.3mm.

[0132] Ideally, the horizontal dimension of the entire external module should not exceed the width of an existing iPhone, thus ensuring ease of use for the user when the phone is attached. For example, the length, width, and height dimensions of a current iPhone are as follows:

[0133] iPhone SE:138.4mm*67.3mm*7.3mm

[0134] iPhone 16Pro:149.6mm*71.5mm*8.25mm

[0135] iPhone 16:147.6mm*71.6mm*7.8mm

[0136] iPhone 16Pro Max:163mm*77.6mm*8.25mm

[0137] Since MagSafe magnets need to be installed inside the phone's bonding surface, according to relevant standards, the size of the magnetic ring is φ=46-54mm, while the diameter of the charger is 55.53mm-55.92mm.

[0138] Based on the above specifications, a width of 56mm-67.3mm for the phone bonding surface 101 is preferable. Ideally, the maximum width of the entire external module's host side 1 should also fall within this size range.

[0139] Example 10

[0140] Preferably, the main control board is equipped with a WIFI and / or Bluetooth communication module. This allows the main control board to communicate wirelessly with mobile phones (or even broadcast to multiple mobile phones). This is simpler and more convenient than a data cable connection, especially in scenarios with narrow signal bandwidth, low real-time performance, and low stability.

[0141] Example 11

[0142] Preferably, a wireless charging / discharging coil is also provided inside the main body 10 of the mobile phone bonding surface 101 at the position corresponding to the magnetic ring.

[0143] Thus, the host device 10 can charge the mobile phone with the battery inside the host device 10 through the wireless charging and discharging coil, or draw power from the mobile phone through the wireless charging and discharging coil when needed.

[0144] Example 12

[0145] Ideally, both the first cable 13 and the second cable 14 are flat cables to maximize the consistency and fit between the external device and the mobile phone during use.

[0146] Based on the above-described structural and implementation features, this patented mobile phone add-on module is particularly suitable for applications in the following three categories and at least 10 types of products.

[0147] Type 1: Satellite Communication Mobile Phone Add-on Module

[0148] A mobile phone add-in module includes a host end and a device end;

[0149] The host unit includes a main body with a mobile phone bonding surface on the main body and a magnetic ring inside the main body corresponding to the position of the mobile phone bonding surface; the main body also contains a main control board and a battery electrically connected to the main control board.

[0150] The motherboard is electrically connected to a first cable. After passing through the first telescopic adjustment mechanism, the right end of the first cable is led out from the side of the phone's contact surface near the main body and extends to the device end.

[0151] The motherboard is also electrically connected to a second cable, which extends from the side of the phone's contact surface near the main body, and its head is equipped with a data terminal.

[0152] The device includes a housing, on which an external functional mechanism and a fixing mechanism are provided; the first cable of the host end extends into the housing of the device and is electrically connected to the external functional mechanism;

[0153] The external functional components include a satellite antenna module.

[0154] With the satellite antenna module, this product allows mobile phones to communicate with satellites simply by connecting it. Furthermore, in conjunction with Embodiment 8, it enables long-distance connection with mobile phones. This is particularly suitable for the needs of those engaged in fishing at sea, or working in wastelands and oceans. Furthermore, when used with the technical solution of Embodiment 7, the product can be operated directly via the buttons. If the internal Wi-Fi functionality of Embodiment 10 is added, the product itself can become a device for long-range satellite communication and near-range Wi-Fi sharing, making it highly practical.

[0155] Type 1:

[0156] The satellite antenna module includes a satellite positioning antenna.

[0157] Satellite positioning antennas are fairly standard, and can be categorized by function into single-receiver and transceiver types. A single-receiver antenna can enhance the phone's positioning signal strength. A transceiver antenna, on the other hand, can transmit positioning information to positioning satellites (such as GPS, BeiDou, GLONASS, and Galileo) when needed.

[0158] Type 2:

[0159] The satellite antenna module includes a satellite communication antenna.

[0160] This technology allows mobile phones to communicate directly with near-Earth satellites via a satellite communication antenna, turning them into satellite phones, especially when there is no mobile signal. By connecting an external device of this type, any mobile phone can gain satellite phone capabilities.

[0161] The optimal satellite communication antenna is connected to the device housing via at least one of the following two methods:

[0162] a. Flexible connecting column;

[0163] b. Universal joint.

[0164] The angle of the satellite communication antenna can be easily adjusted using a gimbal, while the flexible connecting column allows for convenient adjustment of both angle and azimuth. Combining the two allows for rapid adjustment of the angle and fine-tuning of the azimuth.

[0165] Type 3:

[0166] like Figure 13 , 16 As shown, the satellite antenna module includes two satellite communication antennas 26, which are distributed at the farthest ends of the device casing.

[0167] Dual satellite communication antennas provide greater bandwidth, making it possible for mobile phones to transmit video data via satellite. This allows phones that don't inherently have satellite video communication capabilities to communicate in areas without cell phone signal, and even make video calls and live stream videos.

[0168] The structure that places the two satellite communication antennas at the farthest ends of the device's outer casing can maximize the distance between the two antennas, reduce interference, and improve sensitivity.

[0169] Ideally, the satellite communication antenna is connected to the device housing via at least one of the following two methods:

[0170] a. Flexible connecting column; b. Universal joint 25.

[0171] Therefore, the angle of the satellite communication antenna can be easily adjusted via the gimbal 25, while the flexible connecting column facilitates both angle and azimuth adjustments. Both can further increase the distance between the two satellite communication antennas, enhancing their performance. When combined, the distance allows for rapid adjustment of the angle and fine-tuning of the azimuth.

[0172] Type 4:

[0173] The satellite antenna module includes a satellite positioning antenna and a satellite communication antenna.

[0174] This method allows the mobile phone to simultaneously interact with both positioning and communication satellites, and the number of communication antennas can vary depending on the needs of different satellites. Thus, it possesses the advantages mentioned above.

[0175] Type 2: Camera Phone Add-on Module

[0176] like Figure 14 , 17 As shown, for reference Figure 19 , 20 The core difference between this and Type 1 lies in the configuration of the external functional mechanism. By adding a camera module, the boundaries of mobile phone photography and videography are expanded. Combined with Embodiment 7, the product can also be used independently.

[0177] Category 5:

[0178] The external functional mechanism includes a camera module; the camera module is a fill light module.

[0179] Therefore, this device can be transformed into a simple yet effective external photography fill light module, which can be a constant light or a flash, thereby providing fill light for mobile phone photography.

[0180] Category 6:

[0181] The external functional mechanism includes a camera module; the camera module includes a camera with a focal length (e.g., equivalent to 24-35mm focal length), and the camera consists of optical components and corresponding image sensors and photographic sensors 27.

[0182] Because they are not limited by the cramped space of a mobile phone, the camera module of an external mobile phone module can be designed to be more powerful (e.g., with a larger image sensor, more complete optical components, a larger aperture, and even zoom capabilities), thereby greatly expanding the mobile phone's photography and videography capabilities and user experience. Furthermore, the camera sensor 27 can be configured with depth sensors, color temperature sensors, etc., to further enhance the overall photographic effect, as needed.

[0183] Ideally, the camera module also includes a gimbal 24, with the camera 23 mounted on the gimbal, thereby enabling the camera to achieve stabilization, panning, tilting and other camera movement functions.

[0184] Type 7:

[0185] The external functional mechanism includes a camera module; the camera module includes cameras with at least two focal lengths (such as wide-angle, regular, and telephoto focal lengths, 2-3 of which can be selected for configuration), and a fill light module can be added if needed; the camera includes optical components and a corresponding image sensor.

[0186] This solution not only allows for more powerful cameras without being limited by the narrow space of a mobile phone, but also enables the addition of multiple cameras to cover different focal lengths, resulting in a better photography and videography experience.

[0187] Category 8: Panoramic camera module

[0188] The external functional mechanism includes a panoramic camera module; the panoramic camera module includes one or two panoramic camera modules installed back to back.

[0189] This product uses a panoramic camera; one camera covers a 180-degree frontal view, while two cameras positioned back-to-back cover a 360-degree front and rear view. This allows even phones without panoramic shooting capabilities to take panoramic photos of products by connecting this external product.

[0190] Type 3: Satellite communication + camera mobile phone add-on module

[0191] like Figure 15 , 18 As shown in -20, this type of patented product enables mobile phones to have both satellite communication and photography expansion functions when connected externally.

[0192] Type 9:

[0193] A combination of a camera module and a satellite antenna module can be used as needed.

[0194] This will enhance the photography and video recording capabilities of mobile phones and enable satellite communication. In particular, the future applications of satellite-based video calls and live streaming hold immense potential.

[0195] Category 10:

[0196] Large-scale solution for panoramic cameras + satellite antenna modules

[0197] This technology enables mobile phones to have panoramic photography and video recording capabilities, as well as satellite communication capabilities. In particular, the potential for future applications such as satellite-based video calls and live streaming is enormous.

[0198] In summary, the mobile phone add-on module solution provided by this utility model not only adopts a separate structure of host and device ends, ensuring that the product's external size can be minimized as much as possible, but also ensures that the device end, with functions such as satellite communication and photography, can work normally, achieving a balance between the two. The magnetic ring on the host end ensures convenient and quick use, while the device end uses a fixing mechanism to connect to the edge of the phone, ensuring stability. Furthermore, details such as the first cable between the host and device ends, the storage structure of the second cable connecting the host end to the phone, the cable shape, and the placement have all been optimized. This ensures that the product is compact when stored and "unobtrusive" when unfolded.

[0199] Furthermore, this patent involves extensive research and various optimization solutions on how to effectively position the device at the edge of the phone while minimizing intrusion into the phone's display. This ensures that even with this patented product attached, the phone's screen's functional modules and content remain unobstructed, meeting the high-quality usage requirements of scenarios such as live video streaming and satellite video calls.

[0200] In addition, this patent also provides some ingenious structural designs for the corresponding host and device ends, so that the host and device ends can be well connected and stored when stored, and have a longer lifespan and are durable during repeated storage and opening.

[0201] Furthermore, this patented solution can also enable the entire product to work either as an external attachment to a mobile phone or independently of a mobile phone by adding a human-computer interaction module.

[0202] Overall, while the individual technical solutions of this patent are not complex, the principle of simplicity is paramount. Finding a suitable combination of seemingly simple, direct, and stable technical solutions to form a complete product is exceptionally difficult, and this is precisely the challenge this patent overcomes. The entire patent solution is well-designed and sophisticated, not only ingenious but also particularly adaptable to the usage environment that will arise with the subsequent expansion of mobile phone communication and photography needs.

[0203] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "one example," "some embodiments," "example," "an alternative embodiment," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0204] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural 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.
