DETAILED DESCRIPTION

[0016] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present application.

[0017] The mobile power supply provided in the embodiment of the present application can be used for wireless charging of watches. The watch referred to in this application should be understood as: a device worn on the user's wrist and having display functions such as time, including smart watches, bracelets, etc.

[0018] It should be noted that the number of wireless charging points on a power bank is not unique, and the shapes and structures of different points can vary to accommodate different types of devices to be charged. For example, in one embodiment, the power bank may include at least one point for wirelessly charging a watch (which may be magnetic or non-magnetic) and at least one point for charging an electronic device such as a mobile phone (which may be magnetic or non-magnetic).

[0019] Furthermore, in another embodiment, the mobile power supply of the present application can also be configured with a wired charging function, that is, a charging interface is provided on the side of the mobile power supply body, and when the charging cable is inserted into the charging interface, electric energy is output to the device to be charged.

[0020] See also Figure 1 The present application provides a mobile power supply, including: a mobile power supply body 10 and a watch charging component 20, the watch charging component 20 includes a base 21, a wireless charging coil 23, an induction coil 22 and a watch detection module 25, the base 21 is arranged on the surface of the mobile power supply body 10, the wireless charging coil 23 and the induction coil 22 are arranged on the base 21, the watch detection module 25 is respectively connected to the induction coil 22 and the mobile power supply body 10 (the connection relationship diagram is not shown), and the wireless charging coil 23 is connected to the mobile power supply body 10 (the connection relationship diagram is not shown); when the watch to be charged is attached to the watch charging component 20, the electric field of the induction coil 22 will change, and the watch detection module 25 is used to enable the mobile power supply body 10 to charge the watch to be charged when the electric field change of the induction coil 22 is detected.

[0021] Specifically, the mobile power supply body 10 is the part of the mobile power supply used to store electrical energy and manage the stored electrical energy. The wireless charging coil 23 is the coil used to couple with the coil of the watch to be charged, and transmit electrical energy to the coil of the watch to be charged through the principle of electromagnetic induction, so as to charge the watch to be charged. The induction coil 22 is the coil used to sense the electric field changes caused by the attachment of the watch to be charged and the watch charging component 20. The watch detection module 25 is used to detect the electric field changes caused by the attachment of the watch to be charged around the induction coil 22, and transmit the electric field change signal to the mobile power supply body 10, thereby realizing a device that charges the watch to be charged as soon as it is attached. The watch detection module 25 can be set on the base 21, or on the surface of the mobile power supply body 10, or inside the mobile cabinet power supply body 10, without specific limitation.

[0022] In practical scenarios, the base 21 can be disposed on any surface of the mobile power supply body 10, or on multiple surfaces of the mobile power supply body, etc., without specific limitation. If the watch to be charged is not attached to the watch charging assembly 20, the magnetic field around the induction coil 22 is a fixed magnetic field. At this time, the watch detection module 25 detects that the signal is a fixed signal. The watch detection module 25 can output a signal (e.g., a low-level signal) to the mobile power supply body 10 indicating that the watch to be charged is not attached, or it can output no signal to the mobile power supply body 10.

[0023] When the watch to be charged is attached to the watch charging assembly 20, the wireless charging coil 23 of the watch charging assembly 20 couples with the coil of the watch to be charged, causing the magnetic field around the induction coil 22 to change. This magnetic field change further causes the electric field to change, and the watch detection module 25 detects the fluctuation in the electric field signal. The watch detection module 25 detects this change and sends an electric field change signal (which can be a signal related to the electric field strength or a high-level signal) to the mobile power supply body 10, thereby activating the charging function of the mobile power supply body 10. The stored electrical energy in the mobile power supply body 10 is then transferred to the wireless charging coil 23 and then to the watch to be charged via electromagnetic induction.

[0024] Furthermore, when the watch to be charged leaves the watch charging assembly 20, the wireless charging coil 23 of the watch charging assembly 20 separates from the charging coil of the watch to be charged, causing the magnetic field (or electric field) surrounding the induction coil 22 to return to its pre-charging state. The watch detection module 25 can also detect this electric field change and transmit it to the mobile power supply body 10, thereby causing the mobile power supply body 10 to terminate the charging function. In this way, the mobile power supply's charging function can be promptly interrupted when the user does not need to charge, reducing energy waste and meeting both the demand for instant charging and the demand for low power consumption in standby mode.

[0025] In the above solution, the power bank includes a power bank body 10 and a watch charging assembly 20. The watch charging assembly 20 includes a base, a wireless charging coil 23, an induction coil 22, and a watch detection module 25. The base 21 is disposed on the surface of the power bank body 10, and the wireless charging coil 23 and induction coil 22 are disposed on the base 21. The watch detection module 25 is connected to the induction coil 22 and the power bank body 10, respectively. The wireless charging coil 23 is also connected to the power bank body 10. Thus, when a watch to be charged is attached to the watch charging assembly 20, the electric field of the induction coil 22 changes. The watch detection module 25 can detect this change in the electric field of the induction coil 22, thereby enabling the power bank body 10 to charge the watch. This solution allows wireless charging of a watch via the power bank without user intervention, achieving instant charging, thus improving the charging convenience of the power bank.

[0026] In some embodiments, the base 21 is movably disposed on the mobile power source body 10 and can move in a direction away from or toward the mobile power source body 10 .

[0027] Specifically, the base 21 is used to adjust the charging position of the watch to be charged. The base 21 is movably mounted on the power bank body 10 and can be moved away from the power bank body 10. Thus, the charging position of the watch to be charged can be adjusted by moving the base 21. It should be noted that the base 21 can be movable in various ways, including rotation, sliding, and other methods, as long as the base 21 can be moved away from or toward the power bank body 10. This is not a specific limitation.

[0028] To facilitate understanding of the technical solution of this application, the following embodiments can be understood as a base 21 being rotatably mounted on the power bank body 10. This allows the wireless charging coil 23 and the induction coil 22 to rotate with the base 21, allowing the watch to be charged to rotate relative to the power bank body 10 during charging, making it easier for the user to use the watch. For example, the rotation of the base 21 allows the user to easily view information such as the time displayed on the watch.

[0029] In some embodiments, the base 21 includes a rotating member and a bracket. The rotating member is disposed on the mobile power supply body 10 , the bracket is connected to the rotating member, and the wireless charging coil 23 and the induction coil 22 are respectively disposed on the bracket.

[0030] Specifically, the rotating member is a component that can rotate, and the bracket is a component used to support the wireless charging coil 23 and the induction coil 22. In this embodiment, the base 21 includes the rotating member and the bracket. While ensuring that the wireless charging coil 23 and the induction coil 22 rotate relative to the base 21, it also provides sufficient installation space for the wireless charging coil 23 and the induction coil 22.

[0031] See also Figure 2 In some embodiments, the bracket includes a first support component 211, a second support component 212 and a cover 213. The induction coil 22 is arranged on the first surface of the first support component 211 and along the edge of the first surface. The first surface is the surface of the first support component 211 away from the mobile power supply body 10; the second support component 212 is arranged on the first surface and is located in the area surrounded by the induction coil 22; the cover 213 is arranged to cover the induction coil 22, and the wireless charging coil 23 is embedded in the interior of the second support component 212, and the distance from the wireless charging coil 23 to the first surface is greater than the distance from the induction coil 22 to the first surface.

[0032] Specifically, in this embodiment, the induction coil 22 (which may be a copper coil, for example) is positioned around the edge of the first surface of the first support member 211. The first surface is specifically the surface of the first support member 211 facing away from the power bank body 10. The surface of the induction coil 22 facing away from the first support member 211 is covered by a cover to prevent the induction coil 22 from being exposed. Within the area surrounding the induction coil 22 on the first surface of the first support member 211, a second support member 212 is positioned, and the wireless charging coil 23 is embedded within the second support member 212. Since the induction coil 22 is positioned on the surface of the first support member 211, its distance from the first surface is zero. Furthermore, the distance from the wireless charging coil 23 to the first surface is greater than the distance from the induction coil 22 to the first surface, meaning that the height of the wireless charging coil 23 is greater than the height of the induction coil 22. This creates a gap between the induction coil 22 and the wireless charging coil 23, reducing interference from the magnetic field of the wireless charging coil 23 on the induction coil 22 and improving the accuracy of the magnetic attraction detection device.

[0033] It should be noted that the shapes of the first support member 211 and the second support member 212 are not limited. In one embodiment, the projections of the first support member 211 and the second support member 212 on a horizontal plane are circular or annular. In other embodiments, the projections of the first support member 211 and the second support member 212 on a horizontal plane may also be other regular shapes (such as a rectangle) or irregular shapes, without limitation.

[0034] See also Figure 3 In some embodiments, the mobile power supply further includes a rotation detection component 40 , which is disposed on the mobile power supply body 10 and is used to detect the rotation angle of the watch charging component 20 .

[0035] Specifically, the rotation detection assembly 40 is a device used to detect the rotation of the base 21 of the watch charging assembly 20. In the solution of this application, the rotation detection assembly 40 is positioned within the power bank body 10 in a position corresponding to the watch charging assembly 20, so that the signal detected by the rotation detection assembly 40 changes with the rotation of the watch charging assembly 20. This solution allows for timely detection of any rotation of the watch charging assembly 20 relative to the power bank body 10, improving the operational reliability of the power bank.

[0036] In one embodiment, the mobile power supply further includes a control mainboard, which is used to control the output level signal of the mobile power supply body 10 based on the rotation angle of the watch charging component 20.

[0037] Specifically, in this embodiment, the rotation detection assembly 40 and the power bank body are each connected to the control board. Upon detecting rotation of the watch charging assembly 20, the rotation detection assembly 40 transmits a signal representing the rotation angle of the watch charging assembly 20 to the control board. Ultimately, the control board transmits different level signals to the power bank body 10 based on the detected rotation angle, causing the power bank body 10 to implement different control schemes. This embodiment establishes a connection between the rotation detection assembly 40 and the power bank body 10 through the configuration of the control board, further improving the operational reliability of the power bank.

[0038] In one embodiment, the control motherboard is used to output a first level signal to the mobile power supply body 10 when it detects that the watch charging component 20 has rotated to a set angle, and output a second level signal to the mobile power supply body when the watch charging component 20 has not rotated or has not rotated to the set angle; the set angle is greater than 0 degrees and less than 90 degrees.

[0039] Specifically, a set angle is pre-stored in the control mainboard. After obtaining the rotation angle of the watch charging component 20, the control mainboard will compare and analyze it with the set angle, and output different level signals according to the different size relationship between the rotation angle and the set angle.

[0040] In more detail, in one embodiment, to ensure that the watch to be charged can be detected in a timely manner when it rotates with the watch charging assembly 20, the set angle can be set to 9 degrees to 12 degrees. The types of the first level signal and the second level signal are not unique. In one embodiment, the first level signal can be a low level signal, and the second level signal can be a high level signal.

[0041] The way in which the rotation detection component 40 detects whether the watch charging component 20 has rotated to the set angle is not unique. In one embodiment, the rotation detection component 40 may include an angle sensor, etc., and directly detect the rotation angle of the watch charging component 20 through the angle sensor.

[0042] See also Figure 4 In another embodiment, the watch charging assembly 20 further includes a magnet 24 disposed on the base 21, and the rotation detection assembly 40 is a magnetic field detection rotating assembly, which is used to determine the rotation angle of the watch charging assembly 20 according to changes in magnetic field strength.

[0043] Specifically, by setting the magnet 24, the watch can be magnetically charged, avoiding interruption of charging due to collision during the charging process, and improving the charging reliability of the watch.

[0044] The magnetic field detection rotating assembly is a device that determines the rotation angle based on the detected magnetic field changes. In the solution of this embodiment, a magnet 24 is provided on the base 21. Therefore, as the base 21 rotates, the relative position of the magnet 24 and the rotation detection assembly 40 will also change, which is specifically manifested as a change in magnetic flux (or magnetic field). In this embodiment, the rotation angle can be represented by the detected magnetic field strength. As the rotation angle increases, the distance between the magnet 24 and the magnetic field detection rotating assembly increases, the magnetic flux decreases, and the corresponding magnetic field strength also decreases. Therefore, by judging whether the magnetic field strength is lower than the set magnetic field strength, it can be determined whether the watch charging assembly 20 has rotated to the set position.

[0045] In another embodiment, the rotation detection component 40 may store a correspondence between the magnetic flux change (or magnetic field strength) and the rotation angle. The rotation detection component 40 only needs to match the detected magnetic flux change with the correspondence to obtain the rotation angle of the watch charging component 20, and finally compare the rotation angle with the set angle.

[0046] See also Figure 5 In some embodiments, the rotation detection component 40 includes a magnetic induction chip U1, a first resistor R1, a first capacitor C1, and a second capacitor C2. The output end OUT of the magnetic induction chip U1 is connected to the first end of the first resistor R1, the first end of the first capacitor C1, and the mobile power supply body 10 (not shown in the figure), the second end of the first resistor R1 is connected to the power supply, the power supply end VCC of the magnetic induction chip U1 is connected to the first end of the second capacitor C2 and the power supply, and the ground end GND of the magnetic induction chip U1, the second end of the first capacitor C1, and the second end of the second capacitor C2 are grounded respectively.

[0047] Specifically, the magnetic induction chip U1 is a micro sensor chip for detecting changes in the magnetic field, which can convert changes in the magnetic field into electrical signals. It generally works based on Faraday's law of electromagnetic induction or physical phenomena such as the Hall effect and the magnetoresistance effect. In the solution of this embodiment, the watch charging component 20 can move relative to the rotation detection component 40, so that the magnet 24 moves relative to the magnetic induction chip U1, thereby changing the magnetic field strength detected by the magnetic induction chip U1 and realizing rotation detection. The power supply operation of the magnetic induction chip U1 is realized through the power supply terminal and the ground terminal of the magnetic induction chip U1; the first resistor R1 is used to provide an initial high level to the rotation detection component 40, so that when no rotation occurs, the mobile power supply body 10 can receive a fixed signal. In the rotation detection component 40, the first capacitor C1 and the second capacitor C2 are used to filter out interference signals, so that the operation of the rotation detection component 40 is more stable.

[0048] In this way, when the watch charging component 20 is in the 0° state (that is, not rotating), the magnetic induction chip U1 detects a strong magnetic field, and at this time, the second level signal (for example, a low level) can be output to the mobile power supply body 10 through the magnetic induction chip U1; when the watch charging component 20 is rotated to the set angle, the magnetic field detected by the magnetic induction chip U1 will be weaker than a specific value, and at this time, the first level signal (for example, a high level) can be output to the mobile power supply body 10 through the magnetic induction chip U1.

[0049] See also Figure 3 In some embodiments, the mobile power supply further includes a display screen 11, which is disposed on the same surface of the mobile power supply body 10 as the watch charging assembly 20. The display screen 11 is connected to the mobile power supply body 10, and the display screen 11 is configured to flip the display content for display when the mobile power supply body 10 receives a first level signal.

[0050] Specifically, the display screen 11 is a device in the power bank body 10 that displays parameters such as the remaining power and the charge / discharge power. It should be noted that the display screen 11 is not limited to a specific type and can be an LED (Light-Emitting Diode) display screen 11 or an OLED (Organic Light-Emitting Diode) display screen 11, without limitation.

[0051] In this embodiment, the display screen 11 has a flip display function. The display screen 11 and the watch charging assembly 20 are located on the same surface of the power bank body 10. In its normal state, that is, when the base 21 of the watch charging assembly 20 is not rotating, the display screen 11 displays the remaining battery level and other information. At this time, the user can view the normal display from one side of the watch charging assembly 20. However, when the base 21 of the watch charging assembly 20 rotates, the display screen 11 is partially or completely obscured when the user views the display screen from one side of the watch charging assembly 20. The user needs to view the display screen from the opposite direction. If the display screen remains unchanged, the display screen will be inverted. Therefore, in the embodiment of the present application, when the base 21 of the watch charging assembly 20 rotates, the rotation detection assembly 40 detects this and sends a corresponding signal to the power bank body 10. Under the control of the power bank body 10, the display screen 11 flips its display screen for easier viewing, effectively improving the convenience of the power bank.

[0052] See also Figure 6In some embodiments, the watch detection module 25 includes an electric field sensing chip U2, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a third capacitor C3, a fourth capacitor C4 and a fifth capacitor C5, the power supply pin VDD of the electric field sensing chip U2 is connected to the first end of the third capacitor C3, the first end of the third capacitor C3 is also connected to the first end of the fourth capacitor C4 and the first end of the second resistor R2, the second end of the second resistor R2 is connected to the power supply, the second end of the third capacitor C3, the second end of the fourth capacitor C4, the ground pin GND of the electric field sensing chip U2 and the first end of the fourth capacitor C4 are connected to the ground pin GND of the electric field sensing chip U2. The first mode pins AHLB are respectively grounded, the second mode pin TOG of the electric field sensing chip U2 is connected to the mobile power body 10 (also known as the RESET terminal in the figure) through the third resistor R3, the detection pin TCH of the electric field sensing chip U2 is connected to the first end of the fourth resistor R4 and the first end of the fifth capacitor C5, the second end of the fourth resistor R4 is connected to the induction coil 22, the second end of the fifth capacitor C5 is connected to the power ground pin of the electric field sensing chip U2, the power ground pin Vss of the electric field sensing chip U2 is grounded, and the output pin OC of the electric field sensing chip U2 is connected to the mobile power body 10 through the fifth resistor R5.

[0053] Specifically, the electric field sensing chip U2 is a chip based on the working principle of the electric field, which can detect and respond to changes in the electric field. In the solution of this embodiment, when the watch to be charged is attached to the watch charging component 20, the magnetic field around the induction coil 22 will change due to the attraction of the magnet 24 or the coupling of the charging coil. The change in the magnetic field will affect the change in the capacitance around the induction coil 22. The electric field sensing chip U2 of the watch detection module 25 senses this change through the fourth resistor R4 and the fifth capacitor C5, and transmits the perception result to the electric field sensing chip U2. Based on the received signal, the electric field sensing chip U2 outputs an electric field change signal to the mobile power supply body 10 via the third resistor R3, causing the mobile power supply body 10 to start the charging operation. The solution of this embodiment uses the electric field sensing chip U2 and its peripheral circuits to build a watch detection module 25, which has high magnetic attraction detection accuracy.

[0054] See also Figure 3 In some embodiments, a receiving cavity 12 is provided on any surface of the mobile power source body 10 , and the watch charging assembly 20 is disposed in the receiving cavity 12 .

[0055] Specifically, this embodiment defines a receiving cavity 12 on any surface of the power bank body 10, and houses the watch charging assembly 20 within the receiving cavity 12. When needed, the watch charging assembly 20 rotates out of the receiving cavity 12, and when not needed, it retracts into the receiving cavity 12. This reduces the risk of collisions with the watch charging assembly 20 when not in use, thereby improving the safety of the power bank body 10.

[0056] In some embodiments, the mobile power supply body 10 includes a shell, a charging and discharging circuit, an energy storage element and a controller. The charging and discharging circuit, the energy storage element and the controller are placed inside the shell. The watch charging component 20 is set on any surface of the shell. The wireless charging coil 23 and the energy storage element are respectively connected to the charging and discharging circuit, and the charging and discharging circuit is connected to the controller.

[0057] Specifically, the structure of the power bank body 10 is not unique. It includes a housing, and the watch charging assembly 20 can be set on any surface of the housing. The controller is respectively connected to the watch detection module 25, the display screen 11, or the rotation detection assembly 40. When the watch detection module 25 detects that the watch to be charged is attached to the watch charging assembly 20, the controller can control the connection between the charging and discharging circuit, the energy storage element, and the wireless charging coil 23 based on the electric field change signal output by the watch detection module 25 to achieve wireless charging operation; when the rotation detection assembly 40 detects that the watch charging assembly 20 has rotated to a certain extent, the controller can control the display content of the display screen 11 to flip according to the signal sent by the rotation detection assembly 40.

[0058] In order to facilitate understanding of the technical solution of the present application, the present application is explained below in conjunction with more detailed embodiments.

[0059] The mobile power supply body 10 of the present application includes a shell, a charging and discharging circuit, an energy storage element and a controller. The watch charging component 20 includes a base 21, a wireless charging coil 23, an induction coil 22, a magnet 24 and a watch detection module 25. A accommodating cavity 12 is opened on one of the surfaces of the shell. The watch charging component 20 can be rotatably set in the accommodating cavity 12. The display screen 11 and the accommodating cavity 12 are set on the same surface of the shell. The rotation detection component 40 and the base 21 are set on the same surface of the mobile power supply body 10. The watch detection module 25 is connected to the induction coil 22. The magnetic induction chip U1 of the rotation detection component 40 is set at a position corresponding to the magnet 24 of the watch charging component 20.

[0060] First, when a user needs to charge their watch, they place it on the watch charging assembly 20. The watch's magnet 24 engages with the magnet 24 of the watch charging assembly 20, coupling the watch's charging coil with the wireless charging coil 23. The magnetic field around the induction coil 22 changes, causing the electric field to change. This change is sensed by the fourth resistor R4 and fifth capacitor C5 of the watch detection module 25, causing the electric field sensing chip U2 in the watch detection module 25 to output an electric field change signal (which can be represented by a level signal) to the power bank 10. The power bank 10 then connects the charging and discharging circuits, the energy storage element, and the wireless charging coil 23, achieving wireless charging. After the watch to be charged leaves the watch charging assembly 20, the electric field around the induction coil 22 returns to its previous state. The fourth resistor R4 and the fifth capacitor C5 of the watch detection module 25 sense this change, causing the electric field sensing chip U2 of the watch detection module 25 to output a stop charging signal. After the controller of the mobile power supply body 10 receives the charging enable signal, it disconnects the connection between the charging and discharging circuit, the energy storage element and the wireless charging coil 23, and ends the charging operation.

[0061] When the user requests to rotate the watch charging assembly 20 (either in the charging or non-charging state), the magnetic sensing chip U1 of the rotation detection assembly 40 performs real-time magnetic field strength detection and compares the detected magnetic field strength with a preset magnetic field strength. If the detected magnetic field strength is greater than the preset magnetic field strength, it indicates that the watch charging assembly 20 has not rotated or is not fully rotated. In this case, a second-level signal is output to the controller of the mobile power supply body 10. If the detected magnetic field strength is less than or equal to the preset magnetic field strength, it indicates that the watch charging assembly 20 has fully rotated. In this case, a first-level signal is output to the controller of the mobile power supply body 10. Upon receiving the first-level signal, the controller sends a flip signal or the flipped display content to the display screen 11, causing the display screen 11 to flip its content.
