[0033] Example 1

[0034] This embodiment provides a portable power bank device, as shown in the instruction manual. Figure 1 Included with instruction manual Figure 2 As shown, the specific solution is as follows:

[0035] The portable power bank device includes a main body 1, which has at least two power mounting positions 10, wherein the at least two power mounting positions 10 are symmetrically arranged; each power mounting position 10 is provided with a locking structure 100 for quick installation and removal of the power supply.

[0036] The main body 1 of the device is provided with a control module 11, which is electrically connected to each of the power supply mounting positions 10 and is used to control the power supply mode. The main body 1 of the device is provided with at least one power supply interface 12 for connecting external devices.

[0037] This embodiment provides a portable power bank device, including a main body 1, as shown in the attached instruction manual. Figure 1 As shown, the main body 1 of the device has at least two power supply mounting positions 10, which are symmetrically arranged, specifically one on each of the opposite sides of the main body 1. This arrangement not only balances the device's center of gravity, preventing wobbling caused by battery installation on one side, making it particularly suitable for mounting on tripods and other support equipment, but also supports simultaneous installation of two batteries, effectively improving the device's battery life. Furthermore, the symmetrical layout promotes even airflow for heat dissipation, enhancing the cooling effect. Each power supply mounting position 10 is equipped with a locking structure 100, which is mainly used to enable quick installation and removal of the power supply, allowing users to easily install or remove the power supply.

[0038] The main body 1 of the device is equipped with a control module 11, which is electrically connected to each power supply mounting position 10 to control the power supply mode. For example, the power supply mode can be automatically adjusted according to the installation status of the power supply (such as single battery or dual battery) and the battery specifications. At the same time, the main body 1 of the device is provided with at least one power supply interface 12, which is used to connect external devices, such as fill lights, cameras, etc., to meet the power needs of different devices.

[0039] Specifically, the power supply mounting position 10 can be detachably connected to the main body 1 via a fixing slot on the main body 1. The quick-release button in the locking structure 100 is linked to the locking latch via a lever mechanism. When the quick-release button is pressed, the latch disengages from the battery slot, thus completing the power supply installation and removal operation, significantly improving the efficiency of power supply installation and removal. The power supply interface 12 is fixed to the surface of the main body 1 via threads or clips, and its internal pins are soldered to the wires inside the main body. The main circuit board of the control module 11 is soldered to the electrical contact piece of the power supply mounting position 10 via copper foil lines to obtain the power status in real time. The output end of the power supply interface 12 is connected to the power output circuit of the control module 11 via wires, and the control module 11 then regulates the output voltage and current. At the same time, the flexible electrical contact piece and the mechanical locking structure are located on the same side, which ensures that the circuit and mechanical connection are disconnected simultaneously during installation and removal, avoiding the risks caused by hot plugging and unplugging.

[0040] Furthermore, the control module 11 integrates a battery type identification chip, which can automatically determine the installation status of a single or dual battery. When a single battery is installed, only position 1 (the battery installation position on the left or right side of the main body 1 can be set as position 1 according to actual needs) is powered. When dual 4S batteries are installed, they are automatically connected in series to output 24V. When encountering mixed-specification batteries, position 1 is given priority for power supply, which effectively solves the battery compatibility problem. In addition, it can monitor the battery temperature and power in real time and provide warnings through LED indicators, improving the safety of use. The multi-specification power supply interface 12 is highly practical. The Type-C port supports the PD fast charging protocol, up to 65W, and can be adapted to various digital devices such as cameras and mobile phones. The DC interface output voltage is adjustable from 5-28V, which can be compatible with fill lights of different power. Furthermore, a dedicated 3-pin socket can be set to match professional photography equipment such as X200, realizing plug-and-play without the need for additional adapters.

[0041] In an optional embodiment, the locking structure 100 includes a quick-release button 1000 and a connecting part 1001. The connecting part 1001 is electrically connected to the control module 11 and is used to connect to a power source. The quick-release button 1000 is used to connect and disconnect the connecting part 1001 from the power source.

[0042] The connecting part 1001 is electrically connected to the control module 11, thereby achieving an electrical connection with the power supply. For example, it connects with the power supply's electrode contacts via a spring-loaded contact, thus transmitting electrical energy from the power supply to the control module 11. The quick-release button 1000 controls the connection or disconnection of the connecting part 1001 from the power supply. Specifically, the quick-release button 1000 and the connecting part 1001 can be linked via a lever mechanism or a linkage structure. When the user presses the quick-release button 1000, mechanical force is transmitted to the connecting part 1001, separating it from the power supply's electrode contacts. Simultaneously, the mechanical locking structure unlocks, enabling quick disassembly of the power supply. When the power supply is installed, the connecting part 1001 automatically connects with the power supply electrodes under the action of a spring or elastic structure, and the quick-release button 1000 resets and locks, ensuring the stability of the electrical connection. This simplifies the power supply installation and removal process, significantly improving ease of use, and is especially suitable for photography scenarios requiring frequent battery replacements.

[0043] In an optional embodiment, the power bank device is further provided with a fixing and locking component 2, which is rotatably connected to the device body 1, and a connection hole 20 for connecting external accessories is formed between the fixing and locking component 2 and the device body 1.

[0044] In an optional embodiment, the fixing and locking assembly 2 includes a fixing part 21, a rotating part 22, an adjusting part 23, and an adjusting shaft 24; one side of the rotating part 22 is rotatably connected to the device body 1, and the other side is rotatably connected to the fixing part 21.

[0045] The connecting hole 20 is formed between the fixing part 21 and the device body 1. The side of the fixing part 21 away from the device body 1 is rotatably connected to the adjusting shaft 24. The adjusting shaft 24 is connected to the adjusting part 23. Specifically, the end of the adjusting shaft 24 away from the fixing part 21 is rotatably connected to the adjusting part 23.

[0046] As per the instruction manual Figure 3 As shown, the fixing and locking assembly 2 and the main body 1 are rotatably connected by a rotating shaft. The connection hole 20 formed by the two is circular or polygonal and is used to fit external accessories such as tripod poles and supplementary lighting frames.

[0047] Furthermore, the fixing and locking assembly 2 includes a fixing part 21, a rotating part 22, an adjusting part 23 and an adjusting shaft 24, wherein one side of the rotating part 22 is rotatably connected to the side of the device body 1 via a bearing, and the other side is rotatably connected to the fixing part 21 via a pin.

[0048] The side of the fixing part 21 opposite to the main body 1 is arc-shaped, forming a connection hole 20 for the tubular accessory when they are closed. The bottom end of the fixing part 21 away from the main body 1 is rotatably connected to the adjusting part 23 via a threaded structure. The outer surface of the adjusting part 23 is provided with a knob-like operating part. One end of the adjusting shaft 24 is rotatably connected to the adjusting part 23, and the other end is rotatably connected to the fixing part 21. The adjusting shaft 24 may be provided with an external thread, and the through hole connecting the fixing part 21 and the adjusting shaft 24 is provided with a matching internal thread. When the adjusting part 23 is rotated, its internal threaded rod pushes the adjusting shaft 24 to press against, for example, a tripod pole to achieve fixation, and vice versa to unlock. For example, when it is necessary to fix a tripod pole with a diameter of 3cm, rotating the adjusting part 23 causes the adjusting shaft 24 to press against the surface of the pole towards the fixing part 21; when it is necessary to disassemble, rotating the adjusting part 23 in the opposite direction causes the adjusting shaft 24 to move away from the surface of the pole, and the accessory can be quickly removed. Furthermore, a silicone damping layer can be provided on the contact surface between the fixing part 21 and the device body 1. When the connecting hole 20 grips the accessory, the damping layer increases the friction to prevent the device from shaking. This is especially suitable for the stable installation of photographic equipment in bumpy scenes, improving the flexibility of use in photographic scenarios.

[0049] In an optional embodiment, the distance between the fixing part 21 and the device body 1 includes 1cm-5cm.

[0050] Furthermore, a silicone damping sheet can be embedded in the inner wall of the connection hole 20. When the distance is adjusted to grip the attachment, the damping sheet increases the friction through elastic deformation, preventing the device from loosening due to vibration during shooting.

[0051] In an optional embodiment, as shown in the appendix to the specification... Figure 4 As shown, the mobile power device also includes a heat dissipation component 3, and the control module includes a circuit board. The heat dissipation component 3 is disposed on the main body 1 of the device and is thermally connected to the circuit board.

[0052] Specifically, the heat dissipation component 3 can adopt a copper-aluminum composite heat sink structure. The bottom surface is tightly bonded to the heat-generating components of the circuit board (such as power management chips and MOSFETs) via a thermally conductive silicone layer, while the top surface extends to the heat dissipation grooves on the outer casing of the main body 1. The heat dissipation grooves can be arranged in a honeycomb pattern, with the groove openings covered by a metal dustproof mesh to ensure airflow and prevent the intrusion of foreign objects. When the circuit board is operating, heat is transferred to the heat sink through the thermally conductive silicone, and then exchanged with the outside air through the heat dissipation grooves on the outer casing, significantly improving heat dissipation efficiency. In practical applications, the heat dissipation component 3 can also include a metal casing, dissipating heat outwards by directly conducting heat to the heat source.

[0053] In an optional embodiment, each of the power mounting positions 10 is provided with a protective element 5 for protecting the power mounting position 10; the protective element 5 can be a detachable battery cover made of ABS engineering plastic, with a dustproof mesh and / or sealing ring embedded on the inner side. The battery cover is locked to the edge of the power mounting position 10 by a snap-fit ​​structure, and has anti-slip textures on the outer side for easy opening and closing by the user. When the power mounting position 10 is not connected to a battery, the battery cover can prevent dust and liquid from entering the power interface, and at the same time, the internal buffer layer reduces battery shaking, improving the reliability of the device in bumpy environments.

[0054] The portable power bank also includes an external connector 4, which is mounted on the main body 1 and used to connect to external devices. The external connector 4 can be located on the top or side of the main body 1, and includes, but is not limited to, a load-bearing hook and a detachable lanyard. The hook is made of die-cast aluminum alloy and can be attached to objects such as camera backpacks and light stands; the lanyard is made of wear-resistant nylon and its ends are connected to the main body via metal quick-release buckles, allowing users to choose between shoulder or hand carrying. Furthermore, the mounting base of the external connector 4 is fixed to the shell of the main body 1 with screws, and the base has internal reinforcing ribs to ensure connection strength.

[0055] In an optional embodiment, the power supply interface 12 includes one or more of a Type-C interface, a DC interface, a USB-C interface, a MicroUSB interface, and an HDMI interface, thereby meeting the requirements of various devices.

[0056] Example 2

[0057] This embodiment provides a mobile power system, including the mobile power device mentioned in the technical solution of Embodiment 1.

[0058] This application balances the device's center of gravity by symmetrically setting power installation positions on both sides of the main body, avoiding shaking when installing batteries on one side, and is compatible with the stable installation of support equipment such as tripods; the locking structure significantly improves disassembly and assembly efficiency compared to traditional screw fixing methods, and has multiple charging interfaces, making it highly adaptable.
