[0002] With the widespread use of smartphones and other smart devices, the requirements for power quality, reliability, convenience, and immediacy of smart devices are constantly increasing. In addition to contact-based wired power transmission, wireless charging devices can also be used for charging. Wireless charging devices support charging the device when it is close to or in contact with the wireless network.

[0003] However, current wireless charging devices on the market can only wirelessly charge one device at a time and do not support simultaneous wireless charging of multiple devices. Furthermore, current wireless charging devices cannot both charge devices and securely attach to objects, requiring users to typically carry multiple devices to meet different needs. Utility Model Content

This improves charging efficiency without mutual interference. Furthermore, the magnetic components can be attached to fixed objects. Therefore, when there is an idle charging component among the at least two charging components, the magnetic component in the idle component can be used to attach it to a corresponding fixed object, thus fixing the charging device in place. This allows the charging device to be used as a fixed support during the charging process, minimizing the risk of slippage caused by an unsecured device or charging device. This expands the application scenarios of the charging device and improves operational convenience.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] According to some embodiments of this application, please refer to Figures 1 to 4 , Figure 1 These are schematic diagrams of the charging device in some embodiments of this application. Figure 2 This is a schematic diagram of the charging device adsorbing the device to be charged in some embodiments of this application. Figure 3 This is a schematic diagram of the charging device adsorbing and fixing objects in some embodiments of this application. Figure 4 This is a schematic diagram of the charging device adsorbing the device to be charged and the fixed object in some embodiments of this application.

[0028] like Figure 1 As shown, the charging device 10 includes a charging body 101 and at least two charging components 102, which are disposed within the charging body 101. Each charging component 102 includes a magnetic attraction component 1021 and a charging coil 1022.

[0029] The magnetic component 1021 is used to attract the device 20 to be charged or to attach to a fixed object 30. A schematic diagram of the magnetic component 1021 attracting the device 20 to be charged can be found here. Figure 2 A schematic diagram of the magnetic component 1021 adsorbing and fixing the object 30 can be found in [reference needed]. Figure 3 A schematic diagram showing that the magnetic component 1021 simultaneously attracts the device to be charged 20 and the fixed object 30 can be found in [reference needed]. Figure 4 At this time, the device to be charged 20 can be a smartphone, smartwatch, or other device that supports wireless charging. The fixed object 30 can be a support frame, pillar, or other magnetic object (such as metal). The charging device 10 can be a power bank or other power supply device.

[0030] The charging coil 1022 is used to charge the device 20 to be charged when the magnetic attachment component 1021 adsorbs the device 20. At this time, the charging coil 1022 is a transmitting coil, and the device 20 to be charged has a receiving coil. The receiving coil is communicatively connected to the transmitting coil. The transmitting coil can emit electromagnetic signals under the action of electricity, and the receiving coil of the device 20 to be charged can receive the electromagnetic signals and convert them into current, thereby achieving the purpose of wireless charging of the device 20 to be charged.

[0031] It is understood that the device to be charged 20 can be charged by the charging device 10 when it is brought near (non-contact) or in contact with the charging device 10.

[0032] In some embodiments, multiple devices can be charged using different layout methods. For example, independent charging components 102 can be provided on both sides of the charging body 101, or multiple charging components 102 can be integrated through a layered structure. In addition, in order to better realize the functions of the magnetic component 1021 and the charging coil 1022, the magnetic component 1021 and the charging coil 1022 are required to be located close to each other.

[0033] In some embodiments, the magnetic component 1021 can be made of highly magnetic materials such as neodymium iron boron magnets, and the charging coil 1022 can be wound with copper wire. Additionally, the charging coil 1022 can be designed as a ring structure, a square structure, or other configurations to adapt to the charging needs of different devices 20 to be charged.

[0034] In some embodiments of this application, the magnetic component 1021 uses a built-in strong magnet to achieve the function of adsorption with the device to be charged 20 or the fixed object 30, and the charging coil 1022 performs wireless charging through the principle of electromagnetic induction when the magnetic component 1021 adsorbs the device to be charged 20.

[0035] According to some embodiments of this application, please refer to Figure 5 and Figure 6 , Figure 5 This is an exploded schematic diagram of the charging device in some embodiments of this application. Figure 6 This is a schematic diagram of the structure of the charging device in some embodiments of this application.

[0036] like Figure 5 and Figure 6 As shown, the charging device 10 also includes a battery cell 103 and a control circuit 104. The battery cell 103 is electrically connected to the control circuit 104, and the control circuit 104 is electrically connected to the charging coil 1022.

[0037] In some embodiments, the battery cell 103 and the control circuit 104 can be electrically connected by wires or soldering, and the control circuit 104 and the charging coil 1022 can be electrically connected by PCB (Printed Circuit Board) traces or wireless communication.

[0038] In some embodiments, the battery cell 103 may be a lithium-ion battery cell, a lithium polymer battery cell, or other types of battery cells, and there is no limitation herein. In addition, in order to increase the capacity of the charging device 10, multiple sets of battery cells 103 may be connected in parallel, and the multiple sets of battery cells 103 may be of the same or different types.

[0039] In some embodiments, the control circuit 104 may include an MCU (Microcontroller Unit), a charging management chip, a communication protocol module, a FOD (Foreign Object Detection) module, etc., and may have functions such as overcharge protection, over-discharge protection, temperature control and foreign object detection.

[0040] In some embodiments of this application, the battery cell 103 serves as an energy storage unit, the control circuit 104 is responsible for power management and signal processing, and the charging coil 1022 is used for electromagnetic induction to transmit electrical energy. Through the integrated design of the battery cell 103 and the control circuit 104, efficient storage and precise distribution of electrical energy can be achieved, ensuring the stability and safety of the charging process. Furthermore, with the battery cell 103 as the core, the collaborative work of the battery cell 103 and the control circuit 104 can optimize the power transmission path, reduce energy consumption, and enhance the overload protection capability of the charging device 10, extending its service life. The electrical connection between the control circuit 104 and the charging coil 1022 enables wireless charging, and combined with the magnetic component 1021, it can simultaneously provide charging services to at least two devices 20, significantly improving charging efficiency.

[0041] According to some embodiments of this application, please refer to Figure 5 , Figure 7 and Figure 8 , Figure 7 These are schematic diagrams of the charging device in some embodiments of this application. Figure 8 This is a partial exploded view of the charging device in some embodiments of this application.

[0042] like Figure 5 , Figure 7 and Figure 8 As shown, the charging device 10 also includes a buffer assembly 105, which is attached to the battery cell 103. The buffer assembly 105 can be made of elastic materials such as rubber, plastic, or foam.

[0043] In some embodiments, the buffer assembly 105 can be directly attached to the surface of the battery cell 103, for example, by using double-sided adhesive, hot pressing, or snap-fit ​​processes to form a stable connection with the battery cell 103. Alternatively, the buffer assembly 105 can be attached to the battery cell 103 using an injection molding process. The buffer assembly 105 can be distributed around the perimeter or in a localized area of ​​the battery cell 103.

[0044] In some embodiments of this application, the buffer component 105 is directly attached to the battery cell 103, which not only does not significantly increase the overall size of the charging device 10, but also ensures the portability of the charging device 10. In cases such as magnetic charging or multi-device charging, the way the buffer component 105 is attached to the battery cell 103 can maintain the stable position of the battery cell 103 and avoid problems such as poor charging contact caused by vibration.

[0045] In some embodiments of this application, the buffer component 105 serves as a component to protect the battery cell 103. The buffer component 105 can protect the battery cell 103. When the charging device 10 is dropped, the buffer component 105 can effectively absorb external impact force, provide buffer force to the battery cell 103, reduce the vibration and mechanical stress of the charging device 10, reduce the risk of deformation or damage to the battery cell 103, and extend the service life of the charging device 10.

[0046] In some embodiments of the application, the buffer assembly 105 may include multiple independent buffer elements. The number of buffer elements can be determined according to the actual situation and is not limited here. When multiple buffer elements are present, the multiple buffer elements can surround each other to form a closed space, a semi-closed space, or a non-closed space.

[0047] In some embodiments, such as Figure 5 As shown, the buffer assembly 105 includes a first buffer 1051, a second buffer 1052, and a third buffer 1053. The first buffer 1051 and the second buffer 1052 are spaced apart, and the third buffer 1053 is disposed between the spaced spaces of the first buffer 1051 and the second buffer 1052. The first buffer 1051, the second buffer 1052, and the third buffer 1053 surround each other to form a first accommodating space, and the battery cell 103 is disposed within the first accommodating space.

[0048] In some embodiments, the first accommodating space formed by the first buffer 1051, the second buffer 1052, and the third buffer 1053 is a non-enclosed space. In this case, the structural design of the non-enclosed space can protect the battery cell 103 while reducing costs and retaining through holes for heat dissipation of the battery cell 103, thus preventing the battery cell 103 from being unable to dissipate heat during operation and thus avoiding performance damage.

[0049] In some embodiments, the first buffer 1051, the second buffer 1052, and the third buffer 1053 can be made of the same or different materials, such as rubber, plastic, foam, or others. It is worth noting that the battery cell 103 may generate heat during operation, requiring the first buffer 1051, the second buffer 1052, and the third buffer 1053 to be heat-resistant and even capable of absorbing heat to prevent damage to the battery cell 103 at high temperatures.

[0050] In one application scenario, the first buffer 1051, the second buffer 1052, and the third buffer 1053 are all made of EVA (Ethylene Vinyl Acetate Copolymer). The EVA buffers can encapsulate the battery cell 103 to enhance its impact resistance. Furthermore, the first buffer 1051, the second buffer 1052, and the third buffer 1053 can be attached to the battery cell 103 using injection molding to achieve the desired structural configuration.

[0051] In some embodiments, when installing the battery cell 103, the first buffer 1051, the second buffer 1052, and the third buffer 1053, the first buffer 1051, the second buffer 1052, and the third buffer 1053 can be assembled into a frame structure first, and then the battery cell 103 can be embedded inside the frame. Alternatively, the position of the battery cell 103 can be fixed first, and then the first buffer 1051, the second buffer 1052, and the third buffer 1053 can be attached around the battery cell 103, respectively; no limitation is imposed here.

[0052] In some embodiments of this application, the third buffer 1053 is located in the gap between the first buffer 1051 and the second buffer 1052, and the three together form a first accommodating space capable of accommodating the battery cell 103. The three-dimensional enclosed structure of the triple buffer can better absorb external impact forces, giving it better shock resistance. In addition, the spaced buffers and the intermediate filling battery cell 103 can form a mechanical complement, reducing material usage while ensuring the buffering effect.

[0053] According to some embodiments of this application, the number of charging components 102 in the charging device 10 can be determined based on the overall volume of the charging device 10, manufacturing cost, and charging requirements, etc., and is not limited here.

[0054] According to some embodiments of this application, please refer to Figure 5The charging device 10 includes at least two charging components 102, including a first charging component 201 and a second charging component 202. The first charging component 201 abuts against the outer side of the first buffer 1051, the second charging component 202 abuts against the outer side of the second buffer 1052, the inner side of the first buffer 1051 abuts against the first surface of the battery cell 103, and the inner side of the second buffer 1052 abuts against the second surface of the battery cell 103.

[0055] In some embodiments, when installing the battery cell 103, the first buffer 1051, the second buffer 1052 and the third buffer 1053, the first buffer 1051, the second buffer 1052 and the third buffer 1053 can be assembled into a frame structure first, and then the battery cell 103 can be embedded inside the frame. Finally, the first charging component 201 and the second charging component 202 can be attached to the outside of the corresponding buffer.

[0056] In some embodiments of this application, the internal and external contact methods between the charging component 102 and the buffer not only ensure stable contact of the charging port in the charging device 10, but also avoid direct pressure on the battery cell 103, achieving layered protection. Furthermore, the charging device 10 of this application includes independently configured first charging component 201 and second charging component 202, which support simultaneous power supply to two devices 20 to be charged. Combined with the fitting design of the buffer and the battery cell 103, it effectively solves problems such as poor contact and unstable charging when multiple devices 20 are charging simultaneously.

[0057] According to some embodiments of this application, please refer to Figure 5 and Figure 8 The charging body 101 includes a first housing 1011 and a second housing 1012. The first housing 1011 and the second housing 1012 are fastened together to form a second accommodating space. A first charging component 201, a second charging component 202, a battery cell 103, a buffer component 105, and a control circuit 104 are disposed in the second accommodating space. The first charging component 201 is disposed near the first surface of the first housing 1011, and the second charging component 202 is disposed near the second surface of the second housing 1012. The first surface of the first housing 1011 and the second surface of the second housing 1012 are disposed opposite to each other.

[0058] In some embodiments, the first housing 1011 and the second housing 1012 are made of plastic material, or the first housing 1011 and the second housing 1012 are made of metal or polymer material. When the first housing 1011 and the second housing 1012 are made of metal, the first housing 1011 and the second housing 1012 can better cooperate with the magnetic attraction component 1021 to achieve the magnetic attraction function.

[0059] In addition, in practical applications, in order to better achieve the adsorption of the device to be charged 20, the outer shell of the device to be charged 20 is usually required to be made of metal.

[0060] In some embodiments of this application, the first charging component 201 is disposed near the first surface of the first housing 1011, and the second charging component 202 is disposed near the second surface of the second housing 1012, with the first and second surfaces arranged opposite each other. This design allows for the formation of independent working spaces for the first charging component 201 and the second charging component 202 within the second accommodating space. By placing the first charging component 201 and the second charging component 202 on opposite surfaces of the first housing 1011 and the second housing 1012, two independent charging needs can be supported simultaneously. This avoids conflicts between the devices 20 to be charged due to size or position, preventing simultaneous charging and improving the multitasking capability of the charging device 10. Similarly, conflicts between the devices 20 to be charged and / or the fixed object 30 due to size or position can also be avoided.

[0061] Furthermore, in some embodiments of this application, the housing fastening structure not only enhances the overall mechanical strength of the charging device 10, but also avoids mutual interference (such as electromagnetic interference) between internal components through the partition design of the second accommodating space, enhances heat dissipation, and ensures the stability of the internal components.

[0062] According to some embodiments of this application, please refer to Figure 5 The control circuit 104 includes a first control circuit and a second control circuit. The first control circuit is disposed on the first circuit board 1041 and connected to the charging coil 1022 of the first charging component 201. The second control circuit is disposed on the second circuit board 1042 and connected to the charging coil 1022 of the second charging component 202. The first circuit board 1041 is electrically connected to the battery cell 103 through the second circuit board 1042.

[0063] In some embodiments of this application, the first circuit board 1041 is electrically connected to the battery cell 103 via the second circuit board 1042. This split design can achieve signal and power transmission between the circuit boards using methods such as pin headers, soldering, or flexible circuit boards. The layout of the first circuit board 1041 and the second circuit board 1042 can be parallel or vertical, and no limitation is imposed here.

[0064] In some embodiments of this application, the split design can employ dual circuit boards to control different charging areas, meaning different charging channels can be controlled independently. Modular connection can be achieved through methods such as pin headers, where the first circuit board 1041 and the second circuit board 1042 are connected using pin headers. This allows the charging device 10 to simultaneously provide wireless power to at least two devices 20 to be charged, enhancing the multitasking capability of the charging device 10. Furthermore, compared to soldering connections, pin header connections reduce thermal stress damage caused by the soldering process, improving product reliability.

[0065] Furthermore, the independent design of the first circuit board 1041 and the second circuit board 1042 optimizes the utilization of the internal space of the charging body 101, reduces circuit interference, and improves charging efficiency. At the same time, the layered circuit design reduces the impact of electromagnetic radiation on the battery cell 103 and extends its lifespan. In addition, the design of connecting the first circuit board 1041 to the battery cell 103 through the second circuit board 1042 simplifies the circuit wiring path, enhances system stability, and facilitates later maintenance and upgrades.

[0066] According to some embodiments of this application, please refer to Figure 5 and Figure 8 Each magnetic attraction component 1021 includes an annular magnetic medium 301 and a positioning magnetic medium 302. The annular magnetic medium 301 is arranged around its corresponding charging coil 1022; the positioning magnetic medium 302 is arranged on one side of its corresponding annular magnetic medium 301.

[0067] In some embodiments of this application, the annular magnetic medium 301 is a magnetic material structure arranged around the charging coil 1022, and its shape is annular to form a magnetic field distribution. The positioning magnetic medium 302 is arranged on one side of the annular magnetic medium 301, and the directional adsorption of the target object (i.e., the device to be charged 20 and the fixed object 30) is achieved by the magnetic pole direction or shape design.

[0068] In some embodiments, the annular magnetic medium 301 can be made of permanent magnet materials such as neodymium iron boron, and the positioning magnetic medium 302 can be a magnet sheet or magnetic ring with a specific magnetic pole arrangement, which is not limited here.

[0069] In some embodiments, the geometrical positional relationship between the annular magnetic medium 301 and the charging coil 1022 can be nested, fitted, or spaced apart. The surface of the positioning magnetic medium 302 can be designed with protrusions, grooves, or magnetic polarity changes to enhance the adsorption and positioning effect.

[0070] In some embodiments of this application, the annular magnetic medium 301 enables a more uniform magnetic field distribution around the charging coil 1022, improving energy transmission efficiency during wireless charging. The single-sided arrangement of the positioning magnetic medium 302 gives the charging device 10 a more precise directionality when adsorbing the device 20 to be charged, preventing the device 20 to be charged from shifting or falling off during charging.

[0071] Based on this, the magnetic component 1021 provided in this application can not only ensure the stability of the magnetic force, but also avoid the interference of magnetic materials on electronic components. At the same time, through the magnetic positioning function, it can achieve precise alignment for charging at least two devices at the same time. This allows the charging device 10 to not only realize the function of charging multiple devices, but also to be firmly attached to the fixed object 30 through the magnetic component 1021 for use as a support, thereby improving the practicality and user experience of the charging device 10.

[0072] According to some embodiments of this application, please refer to Figure 5 and Figure 8 The first housing 1011 and the second housing 1012 are respectively provided with a first receiving groove O1 and a second receiving groove O2. The first receiving groove O1 of the first housing 1011 is used to place at least a portion of the annular magnetic medium 301 in the first charging assembly 201, and the first receiving groove O1 of the second housing 1012 is used to place at least a portion of the annular magnetic medium 301 in the second charging assembly 202. The second receiving groove O2 of the first housing 1011 is used to place at least a portion of the positioning magnetic medium 302 in the first charging assembly 201, and the second receiving groove O2 of the second housing 1012 is used to place at least a portion of the positioning magnetic medium 302 in the second charging assembly 202.

[0073] According to some embodiments of this application, please refer to Figure 5 and Figure 8 The charging device 10 also includes a switch assembly 106, which is disposed on the charging body 101 and connected between the first circuit board 1041 and the second circuit board 1042. The switch assembly 106 is used to form a power supply circuit to the charging coil 1022 when it is turned on and to disconnect the power supply circuit when it is turned off.

[0074] In some embodiments of this application, the switch assembly 106 is a control component disposed within the charging body 101, used to realize the electrical connection between the first circuit board 1041 and the second circuit board 1042, which can be turned on or off by means of physical contact or electronic signal control.

[0075] Specifically, when the switch assembly 106 is turned on, the charging coil 1022 can form a complete power supply circuit through the switch assembly 106, enabling the wireless charging function of the charging device 10 to work normally. When the switch assembly 106 is turned off, the power supply circuit is cut off, and power is stopped to the charging coil 1022.

[0076] In some embodiments, the switching component 106 may be a mechanical switch, for example, to achieve on and off by sliding or pressing; or it may be an electronic switching circuit, such as a MOS (Metal-Oxide-Semiconductor) transistor or a relay control to achieve on and off.

[0077] In some embodiments, the installation location of the switch assembly 106 can be a specific area inside the charging body 101, such as near the circuit board connection, to ensure ease of operation. In multi-device charging scenarios, the switch assembly 106 can be linked to the adsorption state of the magnetic component 1021. For example, it can be automatically triggered to turn on when the device to be charged 20 is adsorbed into place, or the power supply state can be controlled by the user's manual operation.

[0078] In some embodiments of this application, the controllability of the power supply circuit is achieved by setting the switch assembly 106, which can cut off the power supply when charging is not needed, avoiding unnecessary electromagnetic interference and power loss of the charging coil 1022 under no-load conditions, and improving overall energy efficiency. In multi-device charging scenarios (such as dual-device charging), the switch assembly 106 can ensure independent control of multiple independent charging circuits, avoiding power supply instability caused by load changes. In addition, when the control circuit 104 detects a foreign object, the switch assembly 106 can quickly disconnect the power supply circuit, and together with FOD detection, achieve safety protection and reduce the risk of overheating.

[0079] Furthermore, by controlling the on / off state of the switch assembly 106 physically or electronically, the service life of the charging coil 1022 and the circuit boards (i.e., the first circuit board 1041 and the second circuit board 1042) can be extended, while improving the flexibility of user operation. For example, when it is necessary to quickly stop charging, the power can be directly cut off through the switch assembly 106.

[0080] In some embodiments, a first through hole is provided on the first housing 1011 or the second housing 1012, and the first through hole is positioned corresponding to the switch assembly 106, so that the switch assembly 106 is exposed to the user through the first through hole, making it convenient for the user to perform corresponding operations, such as pressing the switch assembly 106.

[0081] According to some embodiments of this application, please refer to Figure 5 and Figure 8The charging device 10 also includes a lighting assembly 107 and a light-shielding assembly 108, which are disposed on the charging body 101. The lighting assembly 107 includes a plurality of indicator lights, and the light-shielding assembly 108 includes a plurality of non-connected recesses, with each indicator light placed in one recess.

[0082] In some embodiments, the multiple grooves of the light-shielding component 108 can be designed using an injection molding process, and the material used to manufacture the light-shielding component 108 can be engineering plastics, rubber, or others. Furthermore, the shapes of the multiple grooves can be the same or different, and their shapes can be circular, elliptical, or irregularly shaped grooves, etc., to accommodate different display lights.

[0083] In some embodiments, in order to enhance the light-shielding effect of the light-shielding component 108, a light-shielding coating may be provided on the surface of each groove in the light-shielding component 108.

[0084] In some embodiments of this application, the lighting assembly 107 and the light-shielding assembly 108 work together to achieve status indicator light effects. The indicator lights included in the lighting assembly 107 can emit light independently through the non-connected grooves included in the light-shielding assembly 108, avoiding light mixing or cross-contamination, and ensuring that the lighting effect of each indicator light is independent and clear.

[0085] In some embodiments, the lighting assembly 107 includes multiple indicator lights that can display the same or different colors. For example, during charging, using indicator lights of different colors to independently indicate the charging progress can simultaneously reduce the overall power consumption of the product and extend its battery life.

[0086] In some embodiments of this application, the design of the light-shielding component 108 can improve the visibility of the charging device 10 in complex lighting environments while reducing energy waste. Furthermore, the cooperation between the lighting component 107 and the light-shielding component 108 not only ensures directional light output but also avoids light pollution through physical isolation, allowing users to accurately identify the status of the charging device 10.

[0087] In some embodiments, a plurality of second through holes are provided on the first housing 1011 or the second housing 1012, and the plurality of second through holes are correspondingly provided with a plurality of indicator lights, so that each indicator light is exposed to the user through the corresponding second through hole, making it convenient for the user to observe and obtain the corresponding indication information.

[0088] According to some embodiments of this application, please refer to Figure 5 and Figure 8 The charging device 10 also includes a charging port 109, which is disposed on the first circuit board 1041. The first circuit board 1041 is electrically connected to the battery cell 103 through the second circuit board 1042.

[0089] In some embodiments of this application, the charging port 109 is an interface component for connecting to an external power source or device. The charging port 109, located on the first circuit board 1041, enables power transmission. Furthermore, the first circuit board 1041 is electrically connected to the battery cell 103 via the second circuit board 1042. This dual-circuit board structure can achieve electrical conduction using methods such as pin headers, soldering, or flexible contacts. In this case, the first circuit board 1041 can be designed as a main control board containing a charging control chip and interface circuitry, while the second circuit board 1042 serves as a power transmission board connecting the battery cell 103.

[0090] In some embodiments, the connection between the first circuit board 1041 and the second circuit board 1042 can be a direct connection of rigid circuit boards, or a foldable structure can be achieved through a flexible circuit board. The battery cell 103 obtains power input or output through the second circuit board 1042, while the charging port 109 of the first circuit board 1041 can support fast charging protocols such as PD3.0 and QC2.0.

[0091] In some embodiments of this application, the charging port 109 is independently located on the first circuit board 1041 to ensure the durability of the external interface, while the second circuit board 1042, serving as a connection carrier for the battery cell 103, optimizes the internal space layout. This structure facilitates modular production, allowing for individual replacement when the charging protocol needs to be upgraded or the battery cell 103 needs to be replaced.
