Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic devices, and in particular to a wire storage device and a charging assembly. BACKGROUND

[0002] With the popularity of electronic devices, wired charging has become an indispensable part of daily life. Traditional charging wires often appear chaotic during use, not only affecting the appearance, but also possibly causing damage due to winding and pulling. In order to solve these problems, wire storage devices have emerged to manage charging wires neatly and efficiently.

[0003] Current wire storage devices use Pogo pins to ensure the stability of power transmission. The printed circuit board is equipped with contact points, one end of the Pogo pin is electrically connected to the contact points, and the other end of the Pogo pin is connected to the wire. The Pogo pin has an elastic mechanism inside, which can allow a certain range of movement while maintaining contact pressure, ensuring good electrical connection even in dynamic use. When external force acts on the wire, it drives the Pogo pin to rotate, thereby extending or shortening; after removing the external force, the elastic mechanism resets the Pogo pin, completing the storage process.

[0004] However, during use, the Pogo pin and the printed circuit board will frequently come into contact, which can cause aging and wear of both, affecting the stability of power transmission. Inventive content

[0045] Example 1

[0046] As shown in Figures 1 to 3 Example 1 of the present application provides a wire holder, comprising:

[0047] a magnetic coupling module 1 having a transmitting end 11 and a receiving end 12;

[0048] a rebound mechanism 2, the receiving end 12 is located between the transmitting end 11 and the rebound mechanism 2, the rebound mechanism 2 is connected with the receiving end 12, and the wire can be wound on the rebound mechanism 2;

[0049] a control module 3 for electrically connecting with the transmitting end 11, the receiving end 12 and the input end of the wire, respectively, the control module 3 being used for controlling power transmission of the magnetic coupling module 1.

[0050] Specifically, the magnetic coupling module 1 can realize non-contact power transmission through magnetic field coupling, avoid the aging problem of components caused by friction and loss, and improve the long-term reliability and stability of the system. The transmitting end 11 has at least one coil, and the end of the coil of the transmitting end 11 is used to connect with the power supply to generate an alternating magnetic field. The receiving end 12 has at least one coil, and the coil of the receiving end 12 is located in the alternating magnetic field generated by the transmitting end 11. According to the principle of electromagnetic induction, when the coil of the transmitting end 11 generates an alternating magnetic field, the coil of the receiving end 12 generates an alternating voltage due to electromagnetic induction, thereby realizing power transmission.

[0051] The rebound mechanism 2 is used to provide elastic tension, so that the wire can be stretched and stored. The linear storage device can also include a shell having a receiving cavity, and the magnetic coupling module 1, the rebound mechanism 2 and the control module 3 can be located in the receiving cavity and connected with the inner wall of the shell. The receiving end 12 can be located between the central axis and the transmitting end 11, and the rebound mechanism 2 can be connected with the inner wall of the shell by bonding, clamping or other methods. The rebound mechanism 2 can be connected with the wire by clamping, bonding or other methods. When the user pulls the wire, the rebound mechanism 2 is elongated; when the user removes the external force, the rebound force of the rebound mechanism 2 drives the wire to automatically wind back into the storage device, realizing the storage of the wire. The rebound mechanism 2 can be selected from a coil spring, a constant force spring or other mechanical elements that provide elastic tension.

[0052] The control module 3 can ensure the safety, stability and efficiency of power transmission. The control module 3 can include a power input module 31 and a power output module 32. The power input module 31 can be located in the receiving cavity and connected with the inner wall of the shell. The power input module 31 can include a first mainboard, an input interface, a filter capacitor 311 and a bridge driver 312, and the transmitting end 11 can be arranged between the first mainboard and the receiving end 12. The first mainboard can be configured with the filter capacitor 311 and the bridge driver 312, and the input interface, the filter capacitor 311, the bridge driver 312 and the coil of the transmitting end 11 are sequentially electrically connected. Among them, the first mainboard is used to carry the electronic elements of the power input module 31. The input interface is used to be electrically connected with the external power supply, the filter capacitor 311 is located behind the input interface, and is used to smooth the input voltage, remove the ripple and noise in the power supply, and ensure that the subsequent circuit is provided with stable direct current voltage. The bridge driver 312 converts direct current into high-frequency alternating current to excite the coil of the transmitting end 11, and then generates an alternating magnetic field. The shell can have a through hole communicating with the receiving cavity, and the input interface can extend out of the shell through the through hole to realize electrical connection with the external power supply.

[0053] The power output module 32 can be located in the accommodating cavity and connected with the inner wall of the shell. The power output module 32 can be spaced from the rebound mechanism 2. The power output module 32 can include a second mainboard, a rectifier bridge 325 and a capacitor 326, and the receiving end 12 is arranged between the second mainboard and the transmitting end 11. The rectifier bridge 325 and the capacitor 326 can be arranged on the second mainboard. The second mainboard is used to carry electronic components of the power output module 32. The input end of the rectifier bridge 325 is electrically connected with the coil of the receiving end 12 to receive alternating voltage; the output end of the rectifier bridge 325 is electrically connected with the input end of the wire through the capacitor 326 to provide stable direct current power output. The alternating voltage generated by the receiving end 12 is transmitted to the rectifier bridge 325, the rectifier bridge 325 converts the received alternating voltage into pulsating direct current voltage, and the capacitor 326 processes the pulsating direct current voltage to reduce the ripple component in the voltage and provide stable direct current power output.

[0054] The wire receiver provided by the embodiment 1 of the present application realizes non-contact power transmission through electromagnetic coupling between the transmitting end 11 and the receiving end 12 of the magnetic coupling module 1, avoids aging and wear of components caused by frequent use, and improves long-term reliability of power transmission. The automatic winding of the wire is realized through the rebound mechanism 2, which simplifies the wiring and maintenance work of the wire. The power transmission process of the magnetic coupling module 1 is controlled by the control module 3 to ensure the safety, stability and efficiency of the power transmission process.

[0055] As shown in Figure 2 In some embodiments, the transmitting end 11 includes a first magnetic shielding structure 111 and a first coil 112, the first magnetic shielding structure 111 has a ring-shaped first groove 1111, and the first coil 112 is located between the receiving end 12 and the first magnetic shielding structure 111, and the first coil 112 is arranged in the first groove 1111. And / or,

[0056] The receiving end 12 includes a second magnetic shielding structure 121 and a second coil 122, the second magnetic shielding structure 121 has a ring-shaped second groove 1211, and the second coil 122 is located between the transmitting end 11 and the second magnetic shielding structure 121, and the second coil 122 is arranged in the second groove 1211.

[0057] Specifically, the cross-section of the first magnetic shielding structure 111 can be annular or circular, etc. The first magnetic shielding structure 111 can be made of high magnetic permeability materials, such as ferrite, nanocrystalline alloy or silicon steel sheet, etc. High magnetic permeability materials can effectively guide and concentrate the magnetic field, reduce magnetic field leakage, and improve magnetic coupling efficiency. The first recess 1111 is located on the side of the first magnetic shielding structure 111 close to the receiving end 12, and the width and depth of the first recess 1111 can be designed according to the size of the first coil 112 to ensure that the first coil 112 can be tightly embedded in the recess to improve the magnetic coupling efficiency. The cross-sectional shape of the first recess 1111 can be rectangular annular, trapezoidal annular or circular annular, etc.

[0058] The first coil 112 can include one or more independent coil units. For example, the first coil 112 is a single-layer coil or a multi-layer coil, and the specific number of the first coil 112 is determined according to the power demand of power transmission and the magnetic field distribution requirement. The wire of the first coil 112 can use enameled wire or litz wire to reduce the skin effect loss under high-frequency current. The first coil 112 and the first magnetic shielding structure 111 can be fixed by adhesive or buckle to ensure the stability of the position of the first coil 112 in the recess. The first coil 112 can be connected with the power input module 31 by welding or crimping to ensure the stability of current transmission.

[0059] By shielding external magnetic field interference through the first magnetic shielding structure 111, it is ensured that the magnetic field generated by the transmitting end 11 is concentrated and stable, the energy loss of the magnetic field in the transmission process is reduced, and more magnetic flux can be effectively coupled to the receiving end 12. The annular design of the first recess 1111 enables the first coil 112 to be tightly embedded therein, ensuring the close combination of the first coil 112 and the first magnetic shielding structure 111 to concentrate the magnetic field, reduce the diffusion of the magnetic field, improve the magnetic coupling efficiency, and enable the magnetic field to be more concentrated and more efficiently coupled to the receiving end 12, thereby significantly improving the efficiency of power transmission.

[0060] The specific implementation of the second magnetic shielding structure 121 can refer to the specific implementation of the first magnetic shielding structure 111. The specific implementation of the second coil 122 can refer to the specific implementation of the first coil 112, which will not be described here.

[0061] By shielding external magnetic field interference through the second magnetic shielding structure 121, it is ensured that the magnetic field generated by the receiving end 12 is concentrated and stable, the energy loss of the magnetic field in the transmission process is reduced, and more magnetic flux can be effectively coupled to the receiving end 12. The annular design of the second recess 1211 enables the second coil 122 to be tightly embedded therein, ensuring the close combination of the second coil 122 and the second magnetic shielding structure 121 to concentrate the magnetic field, reduce the diffusion of the magnetic field, improve the magnetic coupling efficiency, and enable the magnetic field to be more concentrated and more efficiently coupled to the receiving end 12, thereby significantly improving the efficiency of power transmission.

[0062] The first magnetic shielding structure 111 and the second magnetic shielding structure 121 can be alternatively arranged, or the first magnetic shielding structure 111 and the second magnetic shielding structure 121 can be combined to improve the coupling efficiency.

[0063] As shown in Figure 1 and Figure 2 in some embodiments, further comprising:

[0064] The limiting assembly 4 is located between the resilient mechanism 2 and the receiving end 12, and the limiting assembly 4 is connected with the resilient mechanism 2; the limiting assembly 4 is used to cooperate with the receiving end 12 to constrain the movement path of the wire.

[0065] Specifically, the limiting assembly 4 can be in the form of a plate or a cross-frame structure, etc. The limiting assembly 4 can be connected with the resilient mechanism 2 by clamping, bolting or bonding, etc. The limiting assembly 4 and the receiving end 12 have a certain spacing to form a containing space for containing the wire, which can constrain the wire between the receiving end 12 and the limiting assembly 4, ensure the wire to move along a predetermined path during the pulling and storage process, and ensure the movement path of the wire during the pulling and storage process to achieve the layering winding of the wire, avoid the wire from winding, knotting or deviating during the pulling and storage process, and improve the convenience of use. When the user pulls the wire, the resilient mechanism 2 is elongated and drives the limiting assembly 4 to move, and the limiting assembly 4 cooperates with the receiving end 12 to ensure the wire to move along a predetermined path; when the user removes the external force, the resilient force of the resilient mechanism 2 drives the limiting assembly 4 to move reversely, so that the wire is automatically wound back into the storage device.

[0066] The limiting assembly 4 cooperates with the receiving end 12 to jointly constrain the movement path of the wire, optimizes the pulling and storage process of the wire, reduces friction and wear, prolongs the service life of the wire, and at the same time enhances the structural stability and reliability of the wire storage device, and improves the convenience of use and long-term performance of the wire storage device.

[0067] As shown in Figure 1 and Figure 2 in some embodiments, the limiting assembly 4 comprises:

[0068] The circuit board is located between the resilient mechanism 2 and the receiving end 12, and the circuit board is connected with the resilient mechanism 2, and the control module 3 is arranged on the circuit board.

[0069] Specifically, the circuit board can form a second main board. The cross section of the circuit board can be circular or annular. In the case of the annular circuit board, the resilient mechanism 2 can be located in the inner circle of the annular circuit board, and the resilient mechanism 2 can be connected with the inner side wall of the circuit board by bonding or clamping to optimize the space utilization.

[0070] By cooperating with the receiving end 12, the movement path of the wires is constrained, making the overall structure more compact and optimizing space utilization. Furthermore, the electronic components in the power output module 32 (such as the rectifier bridge 325, capacitor 326, etc.) can be integrated on the circuit board, improving the system integration, reducing the number of components, and lowering the complexity and manufacturing cost of the equipment.

[0071] like Figure 1 and Figure 2 As shown, in some embodiments, it also includes:

[0072] The spacing component 5 has a first end and a second end; the first end is connected to the transmitting end 11; the receiving end 12 has a through hole, and the spacing component 5 is interference-fitted with the through hole; the second end passes through the through hole and is connected to the rebound mechanism 2, and the spacing component 5 enables the transmitting end 11 and the receiving end 12 to maintain a preset distance.

[0073] Specifically, the spacer component 5 is used to maintain the distance between the transmitter 11 and the receiver 12. The spacer component 5 can be made of insulating materials such as plastic or ceramic to avoid interference with the magnetic field. The spacer component 5 can be cylindrical or prismatic. The middle part of the spacer component 5 can protrude radially outward to form a spacer portion. The first magnetic shield structure 111 of the transmitter 11 can be configured with a through hole, which can be located in the first groove 1111. The first end of the spacer component 5 can pass through the through hole and be connected to the inner wall of the housing by means of bonding or snap-fit, etc. The spacer component 5 can be interference-fitted with the through hole. The through hole can be located in the second groove 1211. The second end of the spacer component 5 can be snap-fitted or bonded to the spring mechanism 2. The wire can be connected to the spring mechanism 2 and wound around the spring mechanism 2. The spacer is located between the first magnetic screen structure 111 and the second magnetic screen structure 121, and the second magnetic screen structure 121 and the spacer can be connected by adhesive or bolts, etc. The spacer can maintain a preset distance between the first magnetic screen structure 111 and the second magnetic screen structure 121.

[0074] The distance between the transmitter 11 and the receiver 12 can be 0.5-8mm. For example, the distance between the transmitter 11 and the receiver 12 can be 0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 5.0mm, 7.0mm, or 8.0mm, etc. The smaller the distance between the transmitter 11 and the receiver 12, the larger their mutual inductance coefficient, and the higher the power transmission efficiency. When the first magnetic shield structure 111 and the second magnetic shield structure 121 are simultaneously set, and the distance between them is 0.5mm, the coupling efficiency is measured to be 0.86-0.9 using existing coupling efficiency measurement techniques.

[0075] The spacing assembly 5 ensures the stability and efficiency of power transmission in long-term use by maintaining the distance between the transmitting end 11 and the receiving end 12 to optimize the magnetic coupling efficiency.

[0076] As shown in Figure 1 and Figure 2 In some embodiments, the spacing assembly 5 includes:

[0077] A connecting column 51 having the first end and the second end, the connecting column 51 being interference-fitted with the through hole;

[0078] A spacer 52 located between the limiting assembly 4 and the receiving end 12, the spacer 52 being connected with the limiting assembly 4, and the spacer 52 being in abutment with the receiving end 12.

[0079] Specifically, the first end of the connecting column 51 can be connected with the inner wall of the shell through the through hole by adhesion or clamping, etc. The second end of the connecting column 51 can be connected with the rebound mechanism 2 through the through hole. The spacer 52 can be in a cylindrical shape, the outer wall of the first end of the spacer 52 can be adhesively or clippably connected with the inner ring of the annular circuit board, and the second end of the spacer 52 can be in abutment with the second magnetic shielding structure. The second end of the connecting column 51 can extend into the spacer 52, and the rebound mechanism 2 can be connected with the connecting column 51 and the spacer 52, respectively. The wire can be connected with the outer wall of the spacer 52 by adhesion or buckling. When the user pulls the wire, the wire drives the spacer 52 and the circuit board to rotate, and at the same time, the rebound mechanism 2 is elongated and stores elastic potential energy. When the user removes the external force, the rebound force of the rebound mechanism 2 drives the spacer 52 and the circuit board to rotate reversely, so that the wire is automatically rolled back into the storage device, realizing the storage of the wire.

[0080] In the production process, the connecting column 51 and the spacer 52 can be designed to have a fixed length. The connecting column 51 limits the distance between the transmitting end 11 and the circuit board through its fixed length, and the spacer 52 limits the distance between the receiving end 12 and the circuit board through its fixed length. In this way, the connecting column 51 and the spacer 52 indirectly limit the distance between the transmitting end 11 and the receiving end 12, thereby optimizing the magnetic coupling efficiency and ensuring the stability of power transmission.

[0081] As shown in Figure 3 In some embodiments, the control module 3 includes:

[0082] A voltage stabilizer 321 electrically connected with the receiving end 12;

[0083] At least one converter 322 electrically connected with the voltage stabilizer 321;

[0084] At least one power management integrated circuit 323 is electrically connected to at least one of the converters 322, and the power management integrated circuit 323 is electrically connected to the voltage stabilizer 321, and the power management integrated circuit 323 is connected to at least one sub-input end of the wire in one-to-one correspondence, and the power management integrated circuit 323 can detect the voltage required by the actual load and generate a first signal;

[0085] A controller is signal connected to at least one of the power management integrated circuits 323, and the controller can receive the first signal and control the output voltage of the converter 322 corresponding to the actual load based on the first signal.

[0086] Specifically, the power output module 32 can further include a voltage stabilizer 321, at least one converter 322, at least one power management integrated circuit 323, and a controller configured on a circuit board. The voltage stabilizer 321 is electrically connected to the capacitor 326 of the power output module 32, and the voltage stabilizer 321 is used to stabilize the voltage output by the receiving end 12 within a preset range, ensuring stable operation of the subsequent circuit. The converter 322 is electrically connected to the voltage stabilizer 321, and the converter 322 is used to further adjust the output voltage to meet the needs of different loads. The number of converters 322 can be one or more, and when the number of converters 322 is more than one, for example, the number of converters 322 is two, three, four or even more, the plurality of converters 322 are connected in parallel, and the plurality of converters 322 are electrically connected to the voltage stabilizer 321.

[0087] The power management integrated circuit 323 is used to detect the voltage required by the actual load, and the number of power management integrated circuits 323 is equal to the number of converters 322 and corresponds to each other, and each power management integrated circuit 323 is connected in series with a converter 322. The voltage stabilizer 321 is electrically connected to all power management integrated circuits 323.

[0088] The wire can include a main wire and a plurality of sub-wires, each sub-wire being configured with a sub-input end and a sub-output end, and a first end of the main wire can be connected to the rebounding mechanism 2, and the main wire realizes automatic storage of the wire. Each sub-wire is configured with a sub-input end and a sub-output end, and the number of sub-wires can be equal to the number of power management integrated circuits 323. A second end of the main wire can be connected to the plurality of sub-wires by welding, bonding or other means, and the input end of each sub-wire is electrically connected to a power management integrated circuit 323, and the output end of each sub-wire can be configured with different charging interfaces, and the charging interfaces can be USB Type-C, Micro-USB or other interfaces, to meet the charging needs of different actual loads (such as mobile phones, tablets, etc.).

[0089] The controller is connected to all the power management ICs 323 to receive the first signals from each power management IC 323. Based on the first signals, the controller can control the output voltage of each converter 322 using amplitude shift keying technique to meet the output voltage requirement of the sub-inputs of the wires connected to the different power management ICs 323.

[0090] To save power consumption, all the converters 322 can be in non-working state to reduce unnecessary energy consumption in the absence of actual loads. All the power management ICs 323 enter standby mode, in which they are powered by the voltage regulator 321 to maintain minimal functions. The transmitting end 11 and the receiving end 12 enter standby mode, and the transmitting end 11 transmits low-frequency pulses (e.g. 1 Hz) to ensure that the voltage of the receiving end 12 is maintained at about 5V. In this mode, the system only sends a small amount of pulse signals to maintain the basic functions in standby state, while minimizing power consumption.

[0091] When an actual load is connected, the power management IC 323 detects the voltage required by the actual load (e.g. 9V) and generates the first signal. The controller can receive the first signal, set the reference voltage of the receiving end 12 to 9V, and control the corresponding converter 322 to output 9V and enable the pass-through output to ensure that the actual load is stably powered at 9V.

[0092] When multiple actual loads are connected, the controller can intelligently distribute the voltage requirements of the actual loads. For example, if one actual load requires 9V and another actual load requires 5V, the controller can select the highest voltage 9V as the reference voltage and adjust the corresponding converter 322 to output. In this case, the controller can select one of the converters 322 to output 9V, while the other converters 322 provide appropriate voltages (5V) for other actual loads through internal voltage reduction mechanisms.

[0093] Through the coordinated work of the voltage regulator 321, the converters 322, the power management ICs 323 and the controller, independent power outputs can be provided for multiple loads to meet the voltage requirements of different actual loads. The voltage regulator 321 preliminarily stabilizes the voltage output by the receiving end 12 within a preset range, the power management ICs 323 detect the voltage requirements of the actual loads in real time and generate the first signals, and the controller dynamically adjusts the output voltage of the converters 322 according to the first signals to ensure that each actual load obtains the required power. This dynamic adjustment mechanism avoids power waste and significantly improves system efficiency. In addition, the voltage regulator 321 and the power management ICs 323 together ensure stable voltage output, effectively avoiding the impact of voltage fluctuations on the loads.

[0094] As Figure 3As shown, in some embodiments, the control module 3 includes:

[0095] The analog load 324 is electrically connected to the receiver 12 and the voltage regulator 321 respectively; the analog load 324 is signal connected to the controller, and the controller can adjust the state of the analog load 324 based on the first signal to regulate the output voltage of the transmitter 11.

[0096] Specifically, the power output module 32 may include an analog load 324 configured on a circuit board. The analog load 324 provides a virtual load when no actual load is connected to maintain system stability and regulate the output voltage of the transmitter 11. The analog load 324 is electrically connected to the output of the power output module 32 and the voltage regulator 321 to ensure that it can reflect the voltage status of the system in real time.

[0097] When no actual load is connected, the system enters standby mode. The simulated load 324 sends a feedback signal to the transmitter 11 through the controller to ensure that the voltage of the receiver 12 is maintained at a stable level (e.g., 5V).

[0098] When an actual load is connected, the controller receives the first signal and sets the reference voltage of the receiver 12 (e.g., 9V). At the same time, the controller adjusts the state of the analog load 324 to allocate more power to the actual load and regulates the output voltage of the transmitter 11 to ensure that the actual load receives a stable 9V power supply.

[0099] When multiple actual loads are connected, the controller dynamically adjusts the state of the analog load 324 according to actual needs (e.g., one actual load requires 9V, and another requires 5V). Through priority allocation or dynamic adjustment strategies, the controller ensures that the overall voltage and current distribution of the system is reasonable, avoiding overload or insufficient voltage.

[0100] The simulated load 324 ensures system stability when no actual load is connected, preventing voltage fluctuations and ensuring the system is ready to respond to new load connections. It also reduces power consumption, extends battery life, and minimizes energy waste. When an actual load is connected, the controller dynamically adjusts the state of the simulated load 324 based on load demand, ensuring optimal power resource allocation and preventing overload or insufficient voltage.

[0101] like Figure 3 As shown, in some embodiments, it further includes:

[0102] A trigger unit is connected to the controller via a signal. The trigger unit is used to detect the user's physical operation and generate a second signal. The controller is able to receive the second signal and control the magnetic coupling module 1 to switch operating modes based on the second signal.

[0103] Specifically, the triggering unit can include a button, which can be arranged on the outer wall of the shell to facilitate user operation for generating the second signal after pressing the button. Alternatively, the triggering unit can include a sensor, which can be arranged on the inner wall of the shell and close to the pulling path of the wire, and the wire can contact the sensor during the pulling process and generate the second signal. The sensor can be a mechanical switch, a capacitive touch sensor, a Hall effect sensor, or other types of sensors.

[0104] The controller controls the magnetic coupling module 1 to switch the working mode according to the preset logic. The mode of the magnetic coupling module 1 can include a standby mode and a normal mode. When there is no actual load connected, the magnetic coupling module 1 enters the standby mode to save power as much as possible. At this time, the transmitting end 11 transmits a pulse signal at a low frequency to ensure that the voltage of the receiving end 12 is maintained at a stable level (for example, 5V). When there is an actual load connected, the normal mode can be switched to the normal mode through the triggering unit for normal power transmission. At this time, the transmitting end 11 and the receiving end 12 continuously perform power transmission and adjustment to ensure stable output voltage.

[0105] By introducing the triggering unit, the system can automatically wake up when the user performs a physical operation, switch from the low-power mode to the normal working mode, and improve the response speed and user experience of the system. The controller is responsible for processing these signals and controlling the working mode switching of the magnetic coupling module 1.

[0112] a control module 3 electrically connected with the receiving end 12 and the input end of the wire respectively, the control module 3 is used for controlling the power transmission of the magnetic coupling module 1.

[0113] Specifically, the wire can have one output end; or, the wire can have multiple output ends, for example, two output ends, three output ends, and so on.
