With the increasing expansion and enrichment of the mobile phone ecosystem, various functional hardware devices are increasing more and more, being updated faster and faster, and the power consumption is also increasing day by day.

Detailed implementation manners

[0021] The present invention will be further described in detail below in combination with test examples and specific implementation manners. However, this should not be understood that the scope of the above - mentioned subject matter of the present invention is limited to the following embodiments. All technologies implemented based on the content of the present invention belong to the scope of the present invention.

[0022] Unless otherwise specified, in the description of the specific embodiments of the present invention, the expressions of terms indicating the orientation or positional relationship such as "upper", "lower", "left", "right", "center", "inner", "outer", etc. are all based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the invention product / device / equipment is usually used. These terms of orientation or positional relationship are only for the convenience of describing the solution of the present invention or simplifying the description in the specific embodiments, so as to facilitate technicians to quickly understand the solution, rather than indicating or implying that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, it should not be construed as a limitation to the present invention.

[0023] In addition, for terms such as "horizontal", "vertical", "hanging", "parallel", etc., it does not mean that the corresponding device / component / element is required to be absolutely horizontal or vertical or hanging or parallel, but it can be slightly inclined or deviated. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and it does not mean that the structure must be completely horizontal, but it can be slightly inclined. Or, it can be simply understood that the corresponding device / component / element is arranged in the directions of "horizontal", "vertical", "hanging", "parallel", etc., and can have an error / deviation of ±10% relative to the corresponding direction setting, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still play its role in the solution of the present invention.

[0024] In addition, the expressions such as "first", "second", "third", etc. in the terms are only used to distinguish the description of the same or similar components, and should not be understood as emphasizing or implying the relative importance of a specific component.

[0025] In addition, in the description of the embodiments of the present invention, "several", "multiple", "a number of" represent at least 2. It can be any situation such as 2, 3, 4, 5, 6, 7, 8, 9, etc., and even can be more than 9.

[0026] In addition, in the description of the technical solution of the present invention, unless otherwise clearly specified / defined / restricted, where the terms "set", "installed", "connected", "connected", "provided with", "laid", "arranged" appear, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be connection means commonly used in the art such as welding, riveting, bolting, threaded connection, etc. This kind of connection can be a mechanical connection, an electrical connection or a communication connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements.

[0027] In related technologies, due to the limited size of portable electronic devices, the number of hardware components integrated in portable electronic devices and the size of the battery are limited, which can only meet various conventional functions, forming what is commonly known as a "balanced device". The functions or performance in a single direction are not prominent, and dedicated peripherals need to be adapted to enhance the functions or performance of portable electronic devices. For example, in some existing technologies, it has become increasingly common for portable electronic devices to generate heat, so dedicated radiators for portable electronic devices have emerged on the market; the battery capacity of portable electronic devices is limited and insufficient to support usage, so power banks have emerged on the market, which can supplement the power of portable electronic devices through interfaces or magnetic wireless methods; mobile games are becoming increasingly popular and the market is updated relatively quickly. The original GPUs of some portable electronic devices are difficult to adapt, and more powerful GPUs can be considered to be externally connected to keep up with the market rhythm; some manufacturers have adapted professional imaging kits for portable electronic devices, such as the Xiaomi 15 Ultra, vivo X100 Ultra, and the iPhone imaging kit launched by Leica, etc., which have increased the photography ability and playability of portable electronic devices. However, they are all dedicated to specific models and are difficult to adapt to portable electronic devices of other manufacturers. Thus, it can be seen that if consumers need to expand multiple functions or performance of portable electronic devices, they often need to carry various portable electronic device accessories, and the connection methods of various accessories to portable electronic devices are different. The alternating use of accessories is complicated, and the use of some accessories requires the removal of the protective case of the portable electronic device before connection, which is extremely inconvenient. For this reason, the technical solution of this application is thus generated. The following will be described in conjunction with Figures 1 to 7 for elaboration.

[0028] Embodiment 1 As Figures 1 to 7 shown, a modular peripheral integration box according to the present invention includes a first housing 100 and a second housing 200. The first housing 100 and the second housing 200 are stacked to form a relatively thick protective case, which is applicable to traditional straight-screen portable electronic devices.

[0029] The first housing 100 is used to clamp at least one pair of opposite sides or the four corners of the portable electronic device, and at least one section of the first housing 100 is made of an elastic material; Figure 1 A reference diagram showing the first housing 100 covering the four sides of the portable electronic device is exemplarily given. In some alternative embodiments, one side of the first housing 100 can be made of an elastic material, or two opposite sides can be made of an elastic material, or two adjacent sides can be made of an elastic material, or three sides can be made of an elastic material, or all four sides can be made of an elastic material.

[0030] In some alternative embodiments, auxiliary buttons are provided at the positions corresponding to the side buttons of the portable electronic device on the first housing 100, including volume auxiliary buttons, mute auxiliary buttons, power on / off auxiliary buttons, or the corresponding positions are hollowed out so that the volume buttons, mute buttons, and power on / off buttons of the portable electronic device protrude from the first housing 100. In some alternative embodiments, openings of the same shape are provided at the positions corresponding to the speakers, microphones, etc. of the portable electronic device on the first housing 100.

[0031] As Figure 1 shown, a USB plug 101 is provided inside the first housing 100, and the installation position of the USB plug 101 corresponds to the position of the charging and data interface of the portable electronic device. As can be known to those skilled in the art, since the provided USB plug 101 needs to be circuit-connected, usually the side of the first housing 100 where the USB plug 101 is provided is thicker than the other sides. After the USB plug 101 is inserted into the charging and data interface of the portable electronic device, the portable electronic device can be electrically connected to the integrated box, and the portable electronic device can meet the requirements of charging and data transmission through the external interface (such as the USB interface 204) of the integrated box.

[0032] In some alternative embodiments, metal wires or metal strips are buried near the four corners of the protective case, which can strengthen the transceiver of radio signals.

[0033] As Figure 1 and Figure 2 shown, the second housing 200 includes an inner layer 201 and an outer layer 202. The inner layer 201 is connected to the first housing 100, and the inner layer 201 is used to contact and at least partially cover the back of the portable electronic device. In this embodiment, the situation where the inner layer 201 completely covers the back of the portable electronic device is illustrated; in some alternative embodiments, the outer layer 202 protrudes 2 mm to 5 mm beyond the outer plane of the camera that protrudes from the back of the portable electronic device.

[0034] A closed cavity is formed between the inner layer 201 and the outer layer 202, and a circuit board is provided in the cavity. The circuit board is connected to the USB plug 101; in some alternative embodiments, the inner layer 201 is made of circuit board material, that is, the inner layer 201 can be used as the circuit board, that is, the inner layer 201 and the circuit board can be integrated into one. The materials selected are, for example, metal matrix composites, high-performance engineering plastics, and 3D printing integrated materials; in some alternative embodiments, the outer layer 202 is made of heat-dissipating materials, such as aluminum alloy materials, ABS materials, and copper matrix composites.

[0035] As Figures 1 to 4As shown, a camera hole 203 is reserved at the position of the camera of the portable electronic device on the second housing 200. The shape and size of the camera hole 203 are adapted to the shape and size of the camera of the portable electronic device. The protruding camera of the portable electronic device is incorporated into the camera hole 203 and is tightly separated from the cavity. A transparent camera protection film is covered at the opening of the outer layer 202 and is tightly connected to the outer layer 202 as a whole.

[0036] In some alternative embodiments, such as Figure 2 and Figure 3 shown, the internal space of the cavity is divided into upper and lower parts. The upper and lower parts can be evenly divided according to the horizontal axis, or the lower part of the space can be generally larger than the upper part of the space. In the figure, it is exemplified that the camera hole 203 is located in the upper part of the space. A fixed battery cell 220 is also provided in the upper part of the space and / or at least one card slot is provided on the side of the upper part of the space. The fixed battery cell 220 and the card slot are respectively connected to the circuit board; the planar shape of the fixed battery cell 220 generally adopts a rectangle, but can also adopt a special shape, such as an L shape; for the card slot in the upper part of the space, Figure 3 exemplifies that a relatively large first built-in card slot 240 is provided on the side of the upper part of the space; a position is reserved in the middle of the lower part of the space for arranging a multi-purpose splicing slot 210. The multi-purpose splicing slot 210 is recessed from the outer layer 202 into the lower part of the space, and the multi-purpose splicing slot 210 is isolated from the lower part of the space and is not connected; the edge position of the lower part of the space is used for arranging a circuit function device area 230 and / or at least one of the card slots. The circuit function device area 230 is arranged on the circuit board, and the card slot is connected to the circuit board; the planar shape of the multi-purpose splicing slot 210 can adopt a rectangle, an ellipse or a special shape, Figure 3 exemplifies that the multi-purpose splicing slot 210 adopts a T-shaped planar shape, and the card slots in the lower part of the space include two second built-in card slots 241 with moderate sizes and a third built-in card slot 242 with a smaller size. And, usually, the first built-in card slot 240, the second built-in card slot 241 and the third built-in card slot 242 are centrally arranged along the same side of the cavity (as Figure 3 shown), of course, they can also be dispersed according to specific designs.

[0037] In some alternative embodiments, the multi-purpose splicing slot 210 is detachably connected to an external device. The external device includes an electromagnetic generator module 300, an additional battery cell or a relatively large modular peripheral hardware, Figure 4Illustrates the scenario where the multi-purpose splicing slot 210 is connected to the electromagnetic generator module 300; at least part of the housing of the external device fits into the multi-purpose splicing slot 210, and the external device is connected to the multi-purpose splicing slot 210 by snap connection and / or magnetically connected to the multi-purpose splicing slot 210; the electromagnetic generator module 300 can be used to provide emergency charging for the battery of the portable electronic device and / or the fixed battery cell 220, the additional battery cell can further increase the electric energy storage, and other functions can be expanded through the modular peripheral hardware; a power supply interface and a communication interface are correspondingly arranged between the external device and the multi-purpose splicing slot 210, and the power supply interface and the communication interface are connected to the circuit board. In some specific embodiments, a combined power supply / communication interface can be adopted to realize the power transmission and data transmission between the external device and the portable electronic device.

[0038] In some alternative embodiments, the circuit board adopts a single-layer or multi-layer circuit structure, preferably a multi-layer circuit structure. The circuit board includes a power collection and storage functional circuit, an intelligent charge and discharge functional circuit, and a power supply and data transmission functional circuit, corresponding to the emergency power supply function of the electromagnetic generator module 300 of the integrated box, the power bank function of the additional battery cell, and the hardware expansion function of the modular peripheral hardware respectively. A switch button is further provided on the side of the second housing 200, and the switch button is connected to the circuit board.

[0039] In some alternative embodiments, there are two switch buttons, which respectively control whether the power supply and data between the integrated box and the portable electronic device are connected.

[0040] In some alternative embodiments, the modular peripheral hardware and the multi-purpose splicing slot 210 are correspondingly provided with a power supply interface and a communication interface, both of which are connected to the circuit board. The circuit board includes a power supply and data transmission functional circuit, which is used for the connection between the modular peripheral hardware and the portable electronic device system. Optionally, the power supply and data transmission functional circuit includes a USB main control chip, a USB interface circuit, a high-speed data transmission circuit, ESD (Electro-Static discharge) protection, and a wireless communication module (a Bluetooth module and / or a XingShan module can be selected); the power supply and data transmission functional circuit is used to establish a wired and / or wireless data connection channel between the modular peripheral hardware and the portable electronic device system.

[0041] In some alternative embodiments, the additional battery cell is provided with an energizing interface corresponding to the multi-purpose splicing groove 210. The energizing interface is connected to the circuit board. The circuit board includes an intelligent charge and discharge function circuit. The additional battery cell is used to supply power to the portable electronic device, and the intelligent charge and discharge function circuit is used to charge the battery of the portable electronic device and the additional battery cell under an external power source. Optionally, the intelligent charge and discharge function circuit includes a buck-boost chip, a protocol chip, an input / output interface, a protection circuit, and an intelligent charge / discharge management system. The buck-boost chip and the protocol chip are used to control the dynamic conversion of input and output voltages and intelligent charge management. The input / output interface includes a USB interface 204 for charging input and the USB plug 101, which can charge the battery of the portable electronic device and the battery cells of the integrated box. The intelligent charge / discharge management system includes a power path management IC and a MOSFET. The intelligent charge / discharge management system cooperates with the protocol chip to coordinately control the linked charge and discharge of the battery of the portable electronic device and the additional battery cell. When the USB interface 204 is connected to a power source and enters the charging state, it preferentially charges the battery of the portable electronic device. When not in the external power charging state, it decides whether the battery cell discharges to the battery of the portable electronic device according to the protection value set according to the battery level of the portable electronic device.

[0042] In some alternative embodiments, the electric energy collection and storage function circuit includes a rectifying transformer device 340, a super capacitor 341, and a protection circuit. The electric energy collection and storage function circuit is used for intelligent management when powering the electromagnetic generator module 300.

[0043] In some alternative embodiments, as Figures 4 to 7 shown, the electromagnetic generator module 300 includes a third housing 301 and a hand crank driver. The third housing 301 is provided with an energizing interface corresponding to the multi-purpose splicing groove 210. The energizing interface is connected to the circuit board. A coil stator 330 and a magnet rotor 331 are provided in the third housing 301, and the magnet rotor 331 is connected to the hand crank driver.

[0044] In some alternative embodiments, the rectifying transformer device 340 is provided on the circuit board or in the third housing 301. The rectifying transformer device 340 includes a rectifying circuit and a boost voltage regulator module. The rectifying circuit is used to convert the alternating current generated by the coil stator 330 into direct current, and the boost voltage regulator module is used to boost the current to a specified voltage. The super capacitor 341 is provided on the circuit board or in the third housing 301. The super capacitor 341 receives the current processed by the rectifying transformer device 340 and is used to charge the portable electronic device or the battery cell. Figure 7The scenario where the rectifier transformer device 340 and the supercapacitor 341 are integrated into the electromagnetic generator module 300 is illustrated. When the supercapacitor 341 is disposed on the circuit board, i.e., in the second housing 200, since the supercapacitor 341 has a certain height, it can be disposed on the circuit functional device area 230, which is the area on the circuit board for arranging electronic components that meet the three-dimensional space requirements.

That is, the folding ring 312, the folding sleeve rod 314, and the folding rod 316 can be folded or unfolded in sequence, so that in addition to the function of outputting hand-crank power, the handle also has the function of a portable electronic device bracket, which is convenient for the portable electronic device to be supported on a tabletop or for a person to hold the fingers through the folding ring 312 to enhance the safety of holding.

[0047] In a specific embodiment, the outer diameter of the rotating disk 310 is 40 mm.

[0049] In a specific embodiment, the driving gear 320 is directly driven by the rotating disk 310, and the diameter of the driving gear 320 is less than or equal to the diameter of the rotating disk 310. The speed-increasing transmission gear set 321 can be a combination of multiple double-layer gears meshing in sequence and closely stacked ( Figure 6 and Figure 7 illustrates this situation), or a combination of multiple planetary speed-increasing gear sets stacked, or a combination of double-layer gears and planetary gears. The speed-increasing transmission gear set 321 increases the speed step by step and outputs to the driven gear 322 at the last stage.

[0050] In some alternative embodiments, the gear transmission system further includes a pawl assembly for preventing structural damage caused by sudden changes in the motion state of the gear transmission system.

[0051] In some alternative embodiments, such as Figure 7 shown, the driven gear 322, the magnet rotor 331, and the coil stator 330 are arranged in sequence from inside to outside in the thickness direction of the third housing 301. The coil stator 330 is preferably attached to the third housing 301 to facilitate heat dissipation of the coil stator 330 by using the third housing 301.

[0052] In some alternative embodiments, such as Figure 6 shown, the planar shape of the third housing 301 is in a T shape (matching the multi-purpose splicing groove 210 of the T shape). Two groups of the magnet rotors 331 and the coil stators 330 are symmetrically arranged in the horizontal direction of the T shape, and the gear transmission system is arranged in the vertical direction of the T shape. By increasing the number of groups of the magnet rotors 331 and the coil stators 330, the emergency power generation amount is increased.

[0053] In some alternative embodiments, in addition to Figure 7 the double-overlapping arrangement of the magnet rotors 331 and the coil stators 330 as exemplified; a triple-overlapping manner of the magnet rotors 331, the coil stators 330, and the magnet rotors 331 can also be adopted. When adopting this structural form, a heat conduction member connected to the third housing 301 is added around the coil stator 330, that is, by increasing the magnetic field lines, the emergency power generation amount is increased.

[0054] In some alternative embodiments, the magnet rotors 331 are preferably made of permanent magnets with high magnetic induction, such as Figure 6 shown, multiple pairs of permanent magnets are arranged in a circular shape around the circumference with alternating magnetic poles.

[0055] In some alternative embodiments, the support disk of the winding of the coil stator 330 is made of a silicon substrate, and the coil is wound with high-purity and ultra-fine diameter enameled copper wire into multiple turns.

[0056] The current generated by the coil stator 330 flows into the super capacitor 341 after passing through the rectifying transformer component 340.

[0057] In some alternative embodiments, the material of the third housing 301 is the same as that of the second housing 200.

[0058] In some alternative embodiments, the card slot is used to accommodate and connect the modular peripheral hardware with a smaller size, and has power supply and data connection functions.

[0059] The modular peripheral hardware refers to a specific functional physical device encapsulated into a module, including the main functional hardware of a portable electronic device, auxiliary functional hardware, high-quality multimedia device hardware, end-side AI hardware, optical signal receiving and optoelectronic conversion hardware, physical security device hardware, and / or professional electronic tool replacement hardware supplemented with an APP.

[0060] The main functional hardware of the portable electronic device includes, for example, processors (CPU, GPU, etc.), operating memory, etc.; the auxiliary functional hardware includes, for example, infrared emitters, NFC chips, satellite communication chips, adapters, etc.; the high-quality multimedia device hardware includes, for example, screen mirroring devices, external cameras, projection devices, professional imaging kits, etc.; the edge AI hardware includes, for example, SOC, NPU, etc.; the optical signal receiving and optoelectronic conversion hardware includes, for example, laser sensors, silicon optical chips, etc.; the physical security device hardware includes, for example, USB Keys, dongles, intelligent robots, intelligent driving, and dedicated physical security hardware for remote control of smart homes, etc.; the professional electronic tool replacement hardware assisted by APPs includes, for example, medical biosensors, industrial electromagnetic detection probes, etc.

The modular peripheral hardware is placed in the frame-type slot holder and connected to the circuit board of the integration box through the matching circuit at the end, and then connected to the portable electronic device system through the USB plug 101. In this embodiment, the card slot is sized to match different modular peripheral hardware and is divided into three standard sizes: large, medium, and small (i.e., the first built-in card slot 240, the second built-in card slot 241, and the third built-in card slot 242). Correspondingly, the modular peripheral hardware integrated into the integration box also responds to the three standard sizes. When the modular peripheral hardware responds to the standard size and is integrated with a matching circuit, it can also be directly inserted into the card slot without the frame-type slot holder. Connecting several card slots to the modular peripheral hardware flexibly is a way to upgrade and add functions to the portable electronic device, and it can also be directly applied to the portable electronic device body.

[0062] In some alternative embodiments, when the size of the modular peripheral hardware is too large and exceeds the card slots of the three standard sizes, it can be detachably connected to the multi-purpose splicing slot 210; for example, an additional status display screen, which can be a color screen or an e-ink screen, can be used to prompt the user with information such as battery level, status, and notifications; for example, a radiator, a heat spreader is provided on the inner layer 201 and then connected to the multi-purpose splicing slot 210 through a heat conduction sheet. A liquid cooling and / or air cooling radiator is provided in the multi-purpose splicing slot 210 to dissipate the transferred heat; for example, an external GPU is provided in the multi-purpose splicing slot 210, and the external GPU is encapsulated in a liquid cooling and / or air cooling radiator.

[0063] A modular peripheral integration box described in this embodiment uses the first housing 100 as a protective case for a portable electronic device, which not only protects the portable electronic device but also facilitates the connection and integration of the integration box with the portable electronic device; uses the second housing 200 as a carrier for modular expansion to set up a circuit structure with extended functions; realizes the rapid connection of different modules to the integration box through the multi-purpose splicing groove 210, thereby expanding the functions or improving the performance of the portable electronic device; provides a feasible solution for adding increasingly miniaturized modular peripheral hardware to the portable electronic device through the card slot. Since the card slot in this embodiment has different sizes, it can be used to connect modular peripheral hardware of different sizes, that is, the card slot is applicable to modular peripheral hardware with different functions and sizes; the electromagnetic generator module 300 can supply emergency power to the portable electronic device without an external power source, is independent of external power sources, and has an emergency guarantee function. When users of portable electronic devices are engaged in outdoor activities or encounter long-term power outages due to large-scale natural disasters such as typhoons and earthquakes, this function can support the portable electronic device to resume communication in a short time, which has practical value for personal safety, emergency rescue, disaster relief, and social and economic operation; the additional battery cell can increase the battery capacity of the portable electronic device and improve the battery life of the portable electronic device; the modular peripheral hardware can expand other functions or performance of the portable electronic device; this integration box can meet the needs of users of portable electronic devices to upgrade and add functions to the portable electronic device, giving users the right to make active choices. This solution enables the portable electronic device to more conveniently and efficiently be compatible with necessary physical security hardware devices, enabling users of portable electronic devices to balance safety and convenience when remotely controlling multiple important devices such as personal financial systems, driverless vehicles, and intelligent robots through the portable electronic device; this solution provides conditions for the development of replacing traditional professional electronic tools in various industries with portable electronic devices as the platform, opening up more development space for "portable electronic device +", and further enhancing the value and role of the portable electronic device as a personal integrated terminal platform.

After the up-and-down folding screen portable electronic device is bent, the hinge of the portable electronic device is exposed between the upper integration box and the lower integration box.

[0066] In some alternative embodiments, the upper integration box and the lower integration box are connected by structures such as flexible cloth belts, chains, rubber parts, etc.
