[0044] Reference Figures 1 to 8 In some embodiments, the present invention provides a mobile device photography extension device, comprising:

[0045] The housing 1 is provided with a slot 101 and at least two first interfaces 102. The peripheral wall of the slot 101 is provided with a second interface 1011. The slot 101 is detachably connected to an external electronic device. The second interface 1011 is used to electrically connect to the external electronic device. The two first interfaces 102 are respectively used to connect a mobile device and another external electronic device.

[0046] Control module 2 is located inside housing 1 and is electrically connected to first interface 102 and second interface 1011;

[0047] The energy storage module 3 is located inside the housing 1 and is electrically connected to the control module 2.

[0048] In this embodiment, mobile devices such as mobile phones and tablets can be connected to the mobile device photography extension device of this application through the first interface 102. Simultaneously, external electronic devices are also connected to the device through another first interface 102. The control module 2 can be a PCB board, which acts as a docking station to enable data interaction and communication between the mobile device and the external electronic device, allowing them to work collaboratively. The external electronic device can be a microphone, fill light, memory, and external display, etc. When using a microphone, the microphone is connected to one of the two first interfaces 102, and the other of the two first interfaces 102 is connected to the mobile device. In some embodiments, the first interface 102 and the second interface 1011 may include, but are not limited to, a Type-C interface, a USB-A interface, and an HDMI interface.

[0049] An external electronic device can be plugged into or partially plugged into the slot 101. For example, this plugging can be achieved through the cooperation of a protruding rib structure within the slot 101 and a recessed structure on the external electronic device. Preferably, the slot 101 can accommodate the external electronic device or a portion thereof. A plug on the portion of the external electronic device accommodated within the slot 101 is then inserted into a second interface 1011 on the peripheral wall of the slot 101, thereby enabling the external electronic device to engage with the slot 101. The second interface 1011 is electrically connected to the control module 2, allowing the external electronic device to be electrically connected to the control module 2 via the second interface 1011.

[0050] In some embodiments, an external electronic device can be connected to both the first interface 102 and the second interface 1011 simultaneously. For example, a microphone can be connected to the first interface 102 and a memory 4 can be connected to the second interface 1011 to enable various functional expansions of the mobile device. This is only an illustrative example and not a limitation.

[0051] The power storage module 3 supplies power to the entire photography extension device and external electronic devices connected to it, ensuring their normal operation. When the mobile device runs out of power during photography, the power storage module 3 can charge the mobile device through the control module 2 to maintain its battery life.

[0052] In some embodiments, the start and stop of the control module 2 and the energy storage module 3 can also be controlled by setting a switch for the electrical connection control module 2, which is only an example here.

[0053] This application achieves the following effects by providing a mobile device photography extension device with the above-described structure:

[0054] Firstly, it enhances photography capabilities. The photography extension device of this application enables mobile devices to indirectly connect to various external electronic devices, such as fill lights 5, microphones, and displays, which can significantly improve the photography effect of mobile devices and meet the photography and usage needs of users in different scenarios.

[0055] Secondly, the integrated design eliminates the need for users to frequently switch between mobile devices and multiple external electronic devices, making operation more convenient and efficient.

[0056] Thirdly, it extends the device's battery life. The power storage module 3 supplies power to mobile devices and external electronic devices, extending the device's usage time. Especially in outdoor scenarios where charging is not possible in a timely manner, it ensures the smooth progress of photography work and improves the device's availability and reliability.

[0057] In summary, this application comprises a housing 1, a control module 2, and a power storage module 3. The housing 1 has at least two first interfaces 102, which are respectively connected to the mobile device and an external electronic device. The control module 2 is electrically connected to each interface. During operation, the mobile device and the external electronic device can be connected through the two first interfaces 102, thereby expanding the functionality of the mobile device. Simultaneously, a second interface 1011 is provided on the periphery of a slot 101 on the housing 1. The slot 101 is detachably connected to the external electronic device. The second interface 1011 is electrically connected to the control module 2 and the external electronic device connected to the slot 101. The slot 101 and the second interface 1011 can cooperate to fix the external electronic device. The external electronic device is detachably connected to the slot 101 and electrically connected to the second interface 1011, further expanding the photographic function of the mobile device. The power storage module 3 is located inside the housing 1 and electrically connected to the control module 2, providing power to the entire device and the mobile device. During the mobile device's photographic process, the power storage module 3 continuously supplies power to charge the mobile device, ensuring stable operation of the mobile device without an external power source, extending the device's battery life, ensuring smooth photographic work, and providing high ease of use.

[0058] Please continue to refer to Figures 2 to 4 In some embodiments, the external electronic device proposed in this utility model includes a memory 4, which includes:

[0059] The outer casing 41 is adapted to the slot 101, and the outer casing 41 has a first air outlet 410.

[0060] The first connector 42 is located on the outer casing 41 and can be plugged into the second interface 1011.

[0061] Data disk 43 is located inside the outer casing 41;

[0062] The motherboard 44 is located inside the casing 41 and is electrically connected to the first connector 42 and the data disk 43.

[0063] The first cooling fan 45 is located between the first air outlet 410 and the motherboard 44.

[0064] In this embodiment, the size of the memory 4 is adapted to the size of the slot 101. When the first connector 42 of the memory 4 is inserted into the first interface 102 of the mobile device's camera extension device, an electrical connection is established between the memory 4 and the control module 2. When the mobile device's camera extension device needs to store or retrieve data, the data signal is transmitted to the motherboard 44 of the memory 4 through the first interface 102. The motherboard 44, as the core component for data processing and transmission, receives and parses these signals, and then transmits the data to the data disk 43 for storage according to instructions, or reads data from the data disk 43 and transmits it back to the first interface 102 through the motherboard 44, and then the first interface 102 transmits the data to other modules of the extension device or the connected mobile device.

[0065] Under the control of the motherboard 44, the data disk 43 performs storage operations on the received data. The data disk 43 typically uses flash memory or other storage media to store the data in binary form in a specific memory 4. At the same time, the motherboard 44 is also responsible for managing the data disk 43, such as allocating storage addresses, recording the storage location and status of data, so that data can be quickly and accurately read and modified when needed.

[0066] The main function of the first cooling fan 45 is to dissipate heat when the memory 4 is working, especially when the data disk 43 is performing a large number of data read and write operations. The rotation of the first cooling fan 45 will cause the hot air to flow out through the first air outlet 410, which will promote heat dissipation and prevent the data disk 43, motherboard 44 and other components from being affected by overheating, thus avoiding performance issues or shortened lifespan.

[0067] Please continue to refer to Figure 5 and Figure 6 In some embodiments, the external electronic device proposed in this utility model embodiment includes a fill light 5. The fill light 5 includes a fill light body 51, a first plug-in structure 52 disposed on the fill light body 51, and a second connector 53 disposed on the first plug-in structure 52. The first plug-in structure 52 is adapted to the slot 101, and the second connector 53 is electrically connected to the fill light body 51 and can be plugged into the second interface 1011.

[0068] In some embodiments, the external electronic device further includes a display 6, which includes a display body 61, a second plug-in structure 62 disposed on the display body 61, and a third connector 63 disposed on the second plug-in structure 62. The second plug-in structure 62 is adapted to the slot 101, and the third connector 63 is electrically connected to the display body 61 and can be plugged into the second interface 1011.

[0069] In this embodiment, the fill light 5 includes a fill light body 51, a first plug-in structure 52 disposed on the fill light body 51, and a second connector 53 disposed on the first plug-in structure 52. The fill light body 51 can be a fill light plate, with the side of the fill light plate facing the housing 1 being the light-emitting surface. The side of the fill light plate facing away from the housing 1 is provided with the first plug-in structure 52. The first plug-in structure 52 is adapted to the shape of the slot 101. By aligning the first plug-in structure 52 of the fill light 5 with the slot 101 and inserting it, and by connecting the second connector 53 to the second interface 1011, the physical and electrical connection between the fill light 5 and the mobile device photography extension device can be realized.

[0070] The display 6 includes a display body 61, a second plug-in structure 62 disposed on the display body 61, and a third connector 63 disposed on the second plug-in structure 62. The display 6 can be a portable electronic display screen. The side of the display 6 facing away from the housing 1 is the display screen of the display 6, and the side of the display 6 facing the housing 1 is the back panel of the display 6. The back panel of the display 6 is provided with the second plug-in structure 62, which is adapted to the shape of the slot 101. By aligning the second plug-in structure 62 of the display 6 with the slot 101 and inserting it, and by connecting the third connector 63 to the second interface 1011, the physical and electrical connection between the display screen and the mobile device's photography extension device can be realized. The display screen of the display 6 can display the operation page of the mobile device.

[0071] In some embodiments, not limited to the above-described fill light 5 and display 6, those skilled in the art can achieve a detachable connection with the photographic extension device of this application by adapting the structural design of the fill light 5 and display 6 to the external electronic device of the slot 101.

[0072] Please continue to refer to Figures 1 to 8 In some embodiments, the housing 1 proposed in this utility model includes a first surface 103 and a second surface 104 opposite to each other, and a peripheral wall 105 surrounding the periphery of the first surface 103 and the second surface 104, wherein:

[0073] At least two first interfaces 102 are spaced apart on the peripheral wall 105;

[0074] The first surface 103 is provided with a connection structure 9 for connecting a mobile device, and the second surface 104 is partially thinned to form a slot 101.

[0075] In this embodiment, at least two first interfaces 102 are spaced apart on the peripheral wall 105, allowing the mobile device photography extension device to connect to multiple external electronic devices simultaneously without interference between their connection lines, facilitating user operation and management. For example, a fill light 5, a microphone, or other devices can be connected to different locations on the peripheral wall 105. The interfaces are located on the peripheral wall 105, avoiding the use of space on the first surface 103 and the second surface 104 of the photography extension device, thus contributing to the compactness and stability of the overall device structure. Furthermore, the relatively large space of the peripheral wall 105 allows for flexible layout based on the size, shape, and number of different device interfaces, improving the versatility and expandability of the photography extension device.

[0076] The first surface 103 is provided with a connection structure 9 for connecting the mobile device, which makes the connection between the mobile device and the expansion device more secure. For example, the mobile device is fixed to the expansion device by a specific slot, clip, or magnetic connection structure 9, preventing the device from falling off due to shaking or collision during shooting, thus ensuring the stability and safety of shooting. Connecting the back of the mobile device to the first surface 103 conforms to the user's operating habits, allowing the user to easily operate the screen of the mobile device to set shooting parameters, frame the shot, and perform other operations.

[0077] The thinning of the second surface 104 to form the slot 101 achieves a slim and lightweight design for the photographic extension device of this application. While meeting the installation requirements of the memory 4, it effectively reduces the overall size of the device, making the photographic extension device of this application thinner and lighter, and easier to carry. The slot 101, located on the second surface 104, makes the installation and removal of the memory 4 more convenient. Users can replace the memory 4 at any time as needed. The memory 4, installed in the slot 101, is well protected and less susceptible to external impacts and friction. At the same time, the structure of the slot 101 provides a certain degree of fixation for the memory 4, ensuring its stability during device use and reducing problems such as poor contact caused by shaking or vibration.

[0078] In some embodiments, the housing 1 may be composed of two half-shells or more shell components, which are only illustrative examples here.

[0079] Reference Figures 1 to 8 In some embodiments, the peripheral wall 105 proposed in this utility model embodiment includes a first side wall 1051, a second side wall 1052, a third side wall 1053, and a fourth side wall 1054 connected in sequence, wherein:

[0080] At least one of the first sidewall 1051, the second sidewall 1052, the third sidewall 1053 and the fourth sidewall 1054 is provided with a first interface 102;

[0081] Any one of the first sidewall 1051, the second sidewall 1052, the third sidewall 1053 and the fourth sidewall 1054 has an opening for communicating with the slot 101, and the second interface 1011 is disposed opposite to the opening, and the opening allows the memory 4 to be inserted into the slot 101 in the horizontal direction.

[0082] In this embodiment, preferably, the first interface 102 for connecting to the mobile device is disposed on the first side wall 1051, and the first interface 102 for connecting to the external electronic device is disposed on the second side wall 1052, the third side wall 1053, or the fourth side wall 1054.

[0083] The opening provides a passage for the memory 4 to enter and exit the slot 101, allowing the user to easily insert the memory 4 into the slot 101 through the opening, or remove it from the slot 101 when needed.

[0084] The second interface 1011 is positioned opposite to the opening. When the memory 4 is inserted into the slot 101 through the opening, the second interface 1011, which is positioned opposite to the opening, can provide the memory 4 with a clear insertion direction and docking position, so that the connecting parts on the memory 4 (such as the first connector 42) can be accurately aligned and connected with the second interface 1011, which facilitates disassembly and assembly.

[0085] In some embodiments, the photographic extension device of this application may be a flat cuboid, which is easy to hold.

[0086] Please refer to Figure 8 and Figure 9 In some embodiments, the mobile device photography extension device proposed in this utility model embodiment further includes a heat dissipation mechanism 7 disposed inside the housing 1. The control module 2, the power storage module 3 and the heat dissipation mechanism 7 are arranged sequentially in the horizontal direction. The housing 1 has a first air inlet 106 and a second air outlet 107. The air inlet end of the heat dissipation mechanism 7 is disposed corresponding to the first air inlet 106, and the air outlet end of the heat dissipation mechanism 7 is disposed corresponding to the second air outlet 107.

[0087] In this embodiment, external cooling air can enter the interior of the housing 1 through the first air inlet 106 opened on the housing 1. The air inlet of the heat dissipation mechanism 7 is set corresponding to the first air inlet 106, and the cooling air can be directly guided to the air inlet of the heat dissipation mechanism 7 to provide a cold source for the heat dissipation process.

[0088] After the heat dissipation mechanism 7 is activated, its internal heat dissipation components begin to work. It guides the cooling air entering the air intake to the second air outlet 107, which can actively dissipate heat from the mobile device connected to this photography extension device, and can also dissipate heat from the control module 2 and the power storage module 3, thereby reducing their temperature.

[0089] The hot air that has absorbed heat is discharged outside the device through the second air outlet 107 under the action of the heat dissipation mechanism 7, thus completing the entire heat dissipation cycle.

[0090] Please continue to refer to Figures 1 to 9 Preferably, in this embodiment of the present invention, the first air inlet 106 is disposed on the second side wall 1052, the second air outlet 107 is disposed on the third side wall 1053, and the heat dissipation mechanism 7 includes at least one second heat dissipation fan 71. The second heat dissipation fan 71 is located between the first air inlet 106 and the second air outlet 107. The air inlet end of the second heat dissipation fan 71 is disposed corresponding to the first air inlet 106, and the air outlet end of the second heat dissipation fan 71 is disposed corresponding to the second air outlet 107.

[0091] In this embodiment, the air intake end of the second cooling fan 71 corresponds to the first air inlet 106 located on the second side wall 1052. After starting, the second cooling fan 71 uses the suction force generated by its own rotation to guide external cooling air from the first air inlet 106 into the housing 1. The housing 1 can form an air duct with the housing 1 through the partition, allowing cooling air to circulate. The second cooling fan 71 is located in the air duct.

[0092] The second cooling fan 71 rotates continuously, causing the introduced cool air to form a directional airflow inside the device, pushing the air towards the second air outlet 107 located on the third side wall 1053. During this process, the airflow can simultaneously carry away the heat generated by components such as the control module 2 and the power storage module 3.

[0093] The exhaust end of the second cooling fan 71 corresponds to the second air outlet 107. Under the action of the fan, the hot air carrying heat is smoothly guided to the second air outlet 107 and discharged to the outside of the housing 1, completing the entire heat dissipation airflow circulation process.

[0094] Please continue to refer to Figure 9 Furthermore, the heat dissipation mechanism 7 proposed in this embodiment of the present invention also includes heat dissipation fins 72. The heat dissipation fins 72 are disposed between the second cooling fan 71 and the second air outlet 107. The heat dissipation fins 72 have multiple air passages 721 through which airflow passes. One end of each air passage 721 is disposed corresponding to the air outlet end of the second cooling fan 71, and the other end is disposed corresponding to the second air outlet 107.

[0095] In this embodiment, the heat dissipation fins 72 are typically made of materials with good thermal conductivity, such as metal. When hot air flows through the heat dissipation fins 72, heat is rapidly conducted to the fins and then dissipated into the surrounding air. The heat dissipation fins 72 act as a heat exchanger, accelerating the transfer of heat from hot air to the external environment and further improving the heat dissipation effect. Furthermore, the heat dissipation fins 72 have a large surface area, significantly increasing the contact area with the air. According to the principle of heat transfer, the larger the contact area, the better the heat dissipation effect. When the airflow carrying heat passes through the air channels 721 of the heat dissipation fins 72, the heat can be more fully dissipated into the air, thereby improving heat dissipation efficiency and effectively reducing the temperature of the mobile device, control module 2, and power supply module, ensuring the normal operating temperature of the control module 2, energy storage module 3, and other devices. The multiple air channels 721 on the heat dissipation fins 72 can guide and regulate the airflow. This ensures that the airflow discharged from the outlet of the second cooling fan 71 flows in a predetermined direction, i.e. towards the second air outlet 107, preventing airflow from becoming turbulent and backflowing inside the device, ensuring smooth airflow for heat dissipation, and improving overall heat dissipation performance.

[0096] Please continue to refer to Figure 8 Furthermore, the mobile device photography extension device proposed in this embodiment of the present invention also includes a semiconductor heat sink 8, which is connected between the heat dissipation mechanism 7 and the first surface 103 and electrically connected to the control module 2.

[0097] In this embodiment, the semiconductor heat conductor can be controlled by the control module 2 to actively conduct heat to the mobile device that is close to the first surface, transferring the heat from the mobile device to the heat sink and the heat dissipation fins 72 of the heat sink. For example, the semiconductor heat conductor can achieve directional heat transfer through the grain effect or the Peltier effect, which will not be elaborated upon here.

[0098] By setting up a semiconductor heat conductor, the extended device of this application can quickly and actively transfer the heat from the mobile device that is close to the first surface 103 to the heat dissipation mechanism 7 (e.g., heat dissipation fins 72), which facilitates the heat dissipation mechanism 7 to cool down quickly and greatly improves the heat dissipation efficiency.

[0099] Please continue to refer to Figure 8 In some embodiments, the connection structure 9 proposed in this utility model embodiment includes:

[0100] At least one magnetic suction element 91 is disposed inside the housing 1 and is disposed in close contact with the first surface 103.

[0101] In this embodiment, the working principle of the magnetic chuck 91 is based on the properties of magnetic materials. When the mobile device approaches the first surface 103 of the housing 1, the magnetic chuck 91 generates a magnetic field, which interacts with the attractive components in the mobile device, thereby generating an attractive force. The magnetic attraction can be achieved between the metal casing 41 of the mobile device and the magnetic chuck 91, or an additional magnetic chuck 91 can be provided and connected to the mobile device. The magnetic chuck 91 of this photography extension device connects the extension device and the mobile device through magnetic attraction with the magnetic chuck 91 on the mobile device.

[0102] This application achieves the following beneficial effects by setting the magnetic suction element 91 as the connecting structure 9:

[0103] Firstly, it enables mobile devices to connect to the housing 1 quickly and easily without complicated plugging or snapping operations. Users only need to bring the mobile device close to the housing 1, and it will automatically attach to the housing under magnetic attraction, greatly improving the convenience and efficiency of the connection.

[0104] Secondly, it ensures the stability of the connection between the mobile device and the housing 1 to a certain extent, reduces the possibility of loosening due to slight shaking or movement, and ensures that the mobile device and the extension device maintain a relatively fixed position during the shooting process, which is conducive to the stable transmission of power and data.

[0105] In some embodiments, when the back cover of the mobile device is attached to the first surface 103, the data interface of the mobile device and the first interface 102 may be in a parallel state. In this case, the data interface of the mobile device and the first interface 102 can be connected by setting a data cable.

All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
