Description

Technical Field

[0001] This application relates to the field of wireless charging technology for electronic devices, and more particularly to a terminal charging system. Background Technology

[0002] With the development of wireless charging technology, the power of wireless charging for terminal devices has been greatly improved. During high-power charging of terminal devices, a strong alternating magnetic field is generated between the coil of the charging base and the coil of the terminal device.

[0003] Terminal devices typically have a stand mounted on the back for support. When the device is charging at high power, this stand may encroach on the charging area. If the stand contains metal, it can experience eddy current and hysteresis losses under the influence of a magnetic field, generating heat and potentially causing overheating during charging. Utility Model Content

[0004] This application provides a terminal charging system. When an electronic device is being charged at high power, the bracket will not intrude into the charging area of ​​the electronic device, thereby avoiding the problem of the bracket overheating during high-power charging of the electronic device.

[0005] This application provides a terminal charging system. The terminal charging system includes an electronic device, a charging base, a support, and a movable mechanism. The support is movably connected to the electronic device via the movable mechanism. The charging base is used for wirelessly charging the electronic device. The terminal charging system includes a first state and a second state. In the first state, the entire support is positioned opposite the non-charging area of ​​the electronic device. In the second state, at least a portion of the support is positioned opposite the charging area of ​​the electronic device. When the charging base wirelessly charges the electronic device and the terminal charging system is in the first state, the output power of the charging base is a first output power. When the charging base wirelessly charges the electronic device and the terminal charging system is in the second state, the output power of the charging base is a second output power, which is less than the first output power.

[0006] In this embodiment, when the charging dock wirelessly charges the electronic device and the terminal charging system is in the second state, at least a portion of the bracket is located between the coil of the electronic device and the coil of the charging dock. If the wireless charging power is high at this time, a strong alternating magnetic field will be generated between the coil of the charging dock and the coil of the electronic device. Under the influence of the magnetic field, the metal on the bracket will generate eddy current losses and hysteresis losses, and heat up, causing overheating during charging. Therefore, this application reduces the output power of the charging dock when charging the electronic device to reduce the eddy current losses and hysteresis losses generated by the bracket under the influence of the magnetic field, thereby reducing the heat generation problem of the bracket and avoiding overheating of the bracket when charging the electronic device. When the charging dock wirelessly charges the electronic device and the terminal charging system is in the first state, the entire bracket can be located where the coil of the electronic device and the coil of the charging dock are offset, and the bracket is less affected by the magnetic field during charging. Therefore, the charging dock can output higher power to the electronic device, allowing the electronic device to be charged at high power, thereby improving charging efficiency.

[0007] In some possible implementations, the bracket includes a first end and a second end, wherein in a second state, the first end or the second end of the bracket is positioned opposite to the charging area of ​​the electronic device.

[0008] In this embodiment, when the terminal charging system is in the second state, by setting the end of the bracket to be opposite to the charging area of ​​the electronic device, the portion of the bracket that is opposite to the charging area of ​​the electronic device can be reduced, that is, the portion of the bracket that intrudes into the charging area of ​​the electronic device can be reduced, thereby reducing the risk of the bracket overheating or overheating due to the magnetic field of the electronic device during charging.

[0009] In some possible implementations, in the first state, the direction between the first end of the bracket and the second end of the bracket is the first direction; in the second state, the direction between the first end of the bracket and the second end of the bracket is the second direction, and the second direction is set at an angle to the first direction.

[0010] It is understood that the direction from the first end of the bracket to the second end can be the length direction of the bracket. In this embodiment, the bracket can rotate a certain angle relative to the electronic device about a certain rotation center (e.g., the rotation axis of the movable mechanism), so that the length direction of the bracket switches from the first direction to the second direction, or from the second direction to the first direction. In other words, the bracket can rotate a certain angle relative to the electronic device about a certain rotation center (e.g., the rotation axis of the movable mechanism), so that the terminal charging system switches from the first state to the second state, or from the second state to the first state. The way the terminal charging system switches between the first state and the second state is relatively simple.

[0011] In some possible implementations, the second direction is parallel to the length direction of the electronic device, and the second direction is perpendicular to the first direction.

[0012] It is understood that in this embodiment, when the terminal charging system is in the first state, the bracket can be in a horizontal state, and when the terminal charging system is in the first state, the bracket can be in a vertical state. When the electronic device is charging, the bracket can rotate relative to the electronic device to switch the terminal charging system to the second state, that is, switch to the horizontal state of the bracket. In this way, when the terminal charging system is in the first state, the bracket can avoid the charging area of ​​the electronic device to the greatest extent, reducing the influence of the magnetic field of the charging area of ​​the electronic device on the bracket during charging.

[0013] In some possible implementations, the movable mechanism is positioned opposite the non-charging area of ​​the electronic device. This ensures that the movable mechanism does not encroach on the charging area of ​​the electronic device while it is charging. Furthermore, since the bracket is rotatably connected to the electronic device via the movable mechanism, by misaligning the movable mechanism with the charging area of ​​the electronic device, it can be ensured that the portion of the electronic device connected to the movable mechanism on the bracket can avoid the charging area when charging.

[0014] In some possible implementations, the movable mechanism includes a first connector and a second connector. The second connector is movably connected to the first connector, the first connector is fixedly connected to a bracket, and the second connector is fixedly connected to an electronic device. One of the first and second connectors has a first limiting block, and the other has a first limiting groove and a second limiting groove. In a first state, the first limiting block is located within the first limiting groove; in a second state, the first limiting block is located within the second limiting groove. Thus, the movable mechanism can achieve the switching between the first and second states of the bracket through the cooperation of the first limiting block with the first and second limiting grooves. The structure of the movable mechanism is relatively simple, and the switching of the bracket is relatively convenient.

[0015] In some possible implementations, the second connector is a hollow structure and is fitted over the first connector. The first connector includes a first main body and a first limiting block, with the first limiting block protruding from the outer surface of the first main body. The second connector includes a second main body, a first limiting groove, and a second limiting groove. The second main body surrounds the first limiting block, and the openings of both the first and second limiting grooves are located on the inner surface of the second main body. This simplifies the structure of the movable mechanism and reduces its thickness along its axial direction (i.e., the thickness direction of the electronic device), which is beneficial for the thinning of both the movable mechanism and the terminal charging system.

[0016] In some possible implementations, the bracket is rotatably connected to the electronic device via a first connector and a second connector; the movable mechanism has a rotation axis that passes through the center of the first connector and the second connector; the perpendicular segment from the center of the first limiting groove to the rotation axis of the movable mechanism is the first perpendicular segment, and the perpendicular segment from the center of the second limiting groove to the rotation axis of the movable mechanism is the second perpendicular segment, which is perpendicular to the first perpendicular segment.

[0017] It is understandable that when the electronic device is charging, the first limiting block can move from the first limiting slot to the second limiting slot. In this embodiment, by limiting the relative positions of the first limiting slot and the second limiting slot, when the first limiting block moves from the first limiting slot to the second limiting slot, the first connecting member can rotate 90 degrees or 270 degrees relative to the second connecting member. This allows the bracket to avoid the charging area of ​​the electronic device as much as possible, reducing the influence of the magnetic field of the charging area of ​​the electronic device on the bracket during charging.

[0018] In some possible implementations, at least one of the first limiting groove and the second limiting groove includes a first side, a second side, and a third side connected in sequence, and the included angle between the second side and the first side and the third side is an obtuse angle.

[0019] In this embodiment, by setting the included angles between the second and third sides of the first limiting groove to both obtuse angles, the transition between the second and third sides of the first limiting groove is relatively smooth, which helps to reduce the resistance when the first limiting block moves. This allows the first limiting block to move smoothly along the third side of the first limiting groove to the second limiting groove, realizing the transition of the terminal charging system between the first and second states. It is understood that, in this embodiment, the structure of the first and second limiting grooves makes the rotation of the bracket relative to the electronic device more convenient. The user can rotate the bracket without pressing it.

[0020] Furthermore, in this embodiment, by setting the angle between the second side and the first side of the first limiting groove to an obtuse angle, the first limiting block can also move along the first side of the first limiting groove to the second limiting groove, thereby realizing the switching of the terminal charging system between the first state and the second state. In this embodiment, the rotation method of the bracket is relatively flexible.

[0021] Furthermore, in this embodiment, the length of the first side of the first limiting groove can be set to be relatively small in order to reduce the movement length of the first limiting block.

[0022] In some possible implementations, at least one of the first limiting groove and the second limiting groove includes a first side, a second side, and a third side connected in sequence, wherein the angle between the second side and the first side is an obtuse angle, and the angle between the second side and the third side is an acute angle or a right angle.

[0023] In this embodiment, by setting the included angle between the second and third sides of the first limiting groove to an acute angle or a right angle, when the terminal charging system is in the first state, the third side of the first limiting groove can effectively restrict the rotation of the first limiting block, which is beneficial to improving the stability of the terminal charging system in the first state. Similarly, when the terminal charging system is in the second state, the third side of the first limiting groove can effectively restrict the rotation of the second limiting block, which is beneficial to improving the stability of the terminal charging system in the second state.

[0024] Furthermore, in this embodiment, by setting the angle between the second side and the first side of the first limiting groove to an obtuse angle, the first limiting block can also move along the first side of the first limiting groove to the second limiting groove, thereby realizing the switching of the terminal charging system between the first state and the second state. In this embodiment, the rotation method of the bracket is relatively flexible.

[0025] In some possible implementations, the first connector further includes a second limiting block, which protrudes from the outer side of the first body and is spaced apart from the first limiting block; in the first state, the second limiting block is located in the second limiting groove; in the second state, the second limiting block is located in the first limiting groove.

[0026] In this embodiment, the cooperation between the first limiting block and the first limiting groove and the second limiting groove, as well as the cooperation between the second limiting block and the first limiting groove and the second limiting groove, allows the bracket to rotate relative to the electronic device, enabling the terminal charging system to switch between the first state and the second state. The structure of the moving mechanism is simple and facilitates bracket switching.

[0027] In addition, by setting two limiting blocks (including the first limiting block and the second limiting block) in cooperation with the first limiting groove and the second limiting groove, the first connecting member is less likely to tilt during rotation relative to the second connecting member, which helps to improve the stability of the first connecting member during rotation relative to the second connecting member, thereby improving the stability of the bracket during rotation.

[0028] In some possible implementations, there are two first limiting slots and two second limiting slots, with the two first limiting slots and two second limiting slots arranged alternately around the rotation axis of the movable mechanism. This allows the first connecting member to rotate 90 degrees clockwise, 180 degrees, 270 degrees, or 360 degrees counterclockwise relative to the second connecting member, thereby causing the bracket to rotate 90 degrees clockwise, 180 degrees, 270 degrees, or 360 degrees counterclockwise around the rotation axis of the movable mechanism. The bracket's rotation is quite flexible.

[0029] In some possible implementations, the moving mechanism also includes an elastic element, one end of which abuts against a bracket and the other end against an electronic device.

[0030] In this embodiment, the movement of the first limiting block can be restricted by the cooperation of the elastic element, the first limiting groove and the second limiting groove. At this time, the bracket is not easy to move relative to the electronic device under the action of the elastic force of the elastic element, which helps to ensure the stability of the terminal charging system in the first state and the second state.

[0031] In some possible implementations, the active mechanism further includes an elastic element, which includes a first end, a second end, and a middle portion. The middle portion of the elastic element is located between the first end and the second end and connects the first end and the second end. The middle portion of the elastic element is curved and abuts against the bracket. The first end and the second end abut against the electronic device.

[0032] In this embodiment, the movement of the first limiting block can be restricted by the cooperation of the elastic element, the first limiting groove, and the second limiting groove. At this time, the bracket is less likely to move relative to the electronic device under the elastic force of the elastic element, which helps ensure the stability of the terminal charging system in the first and second states. Furthermore, compared to a spring-based solution, the spring does not require a large compression length, thereby reducing the thickness of the moving mechanism and consequently reducing the thickness of the terminal charging system, which is beneficial for a thinner design.

[0033] In some possible implementations, the first connector is provided with a receiving groove, and a portion of the elastic member is located within the receiving groove. This reduces the thickness of the movable mechanism in the Z-axis direction, thereby reducing the thickness of the terminal charging system in the Z-axis direction, which is beneficial for a thinner design.

[0034] In some possible implementations, the terminal charging system further includes a magnetic component and a magnetic induction sensor. The magnetic component is mounted on a bracket, and the magnetic induction sensor is located in the non-charging area of ​​the electronic device. The electronic device includes a processor electrically connected to the magnetic induction sensor. The magnetic induction sensor is used to detect the magnetic field of the magnetic component and send detection information to the processor, wherein the detection information includes information about the magnetic field of the magnetic component. The processor is used to determine whether the terminal charging system is in a first state or a second state based on the detection information.

[0035] This embodiment uses a combination of a magnetic induction sensor and magnetic components to identify the state of the terminal charging system, that is, the state of the stand, and controls the output power of the charging base based on the state of the stand. The terminal charging system has a simple structure, and the methods for identifying the state of the terminal charging system and controlling the charging power are relatively simple and flexible.

[0036] In some possible implementations, the bracket is strip-shaped, and along its length, the bracket includes a first end and a second end; the magnetic element includes a first magnetic element and a second magnetic element, with the first magnetic element disposed at the first end of the bracket and the second magnetic element disposed at the second end of the bracket; when the terminal charging system is in a first state, the magnetic induction sensor is closer to the first end of the bracket than to the second end of the bracket.

[0037] In this embodiment, the magnetic induction sensor is positioned near the first end of the bracket when the terminal charging system is in the first state. It is understood that when the terminal charging system is in the second state, the magnetic induction sensor is located further away from the first end of the bracket compared to the first state. The magnetic field information detected by the magnetic induction sensor for the first magnetic component differs between the first and second states. For example, the magnetic induction sensor can detect the magnitude of the magnetic field of the first magnetic component. When the terminal charging system is in the first state, the magnetic induction sensor detects a magnetic field of the first magnetic component greater than or equal to a preset value; when the terminal charging system is in the second state, the magnetic field of the first magnetic component detected by the magnetic induction sensor is less than the preset value (including the case where the detected magnetic field is zero, i.e., the terminal charging system cannot detect the magnetic field of the first magnetic component).

[0038] In this way, when the terminal charging system is in the first state, the magnetic induction sensor can send first detection information to the processor of the electronic device. The processor can then determine that the terminal charging system is in the first state based on this first detection information and send first control information to the charging dock. When charging the electronic device, the charging dock can control the output power to the first output power based on the first control information.

[0039] When the terminal charging system is in the second state, the magnetic induction sensor can send second detection information to the processor of the electronic device. The processor can then determine that the terminal charging system is in the second state based on this second detection information and send second control information to the charging dock. When charging the electronic device, the charging dock can control the output power to a second output power based on the second control information. Both the first and second detection information include information about the magnetic field of the first magnetic component, but the first and second detection information are different.

[0040] Furthermore, magnetic induction sensors are installed inside electronic devices, allowing for fast response between the device's processor and the electronic device.

[0041] In some possible implementations, the bracket is strip-shaped, and along its length, the bracket includes a first end and a second end; the magnetic element includes a first magnetic element and a second magnetic element, with the first magnetic element disposed at the first end of the bracket and the second magnetic element disposed at the second end of the bracket; when the terminal charging system is in a first state, the magnetic induction sensor is closer to the second end of the bracket than to the first end of the bracket.

[0042] In this embodiment, the magnetic induction sensor is positioned near the second end of the bracket when the terminal charging system is in the first state. It is understood that when the terminal charging system is in the second state, the magnetic induction sensor is further away from the second end of the bracket compared to the first state. The magnetic field information detected by the magnetic induction sensor for the second magnetic component differs between the first and second states. Thus, when the terminal charging system is in the first state, the magnetic induction sensor can send first detection information to the processor of the electronic device. The processor can then determine that the terminal charging system is in the first state based on the first detection information and send first control information to the charging base. When charging the electronic device, the charging base can control the output power to the first output power based on the first control information. When the terminal charging system is in the second state, the magnetic induction sensor can send second detection information to the processor of the electronic device. The processor can then determine that the terminal charging system is in the second state based on the second detection information and send second control information to the charging base. When charging the electronic device, the charging base can control the output power to the second output power based on the second control information. Both the first and second detection information include information about the magnetic field of the second magnetic component, and the first and second detection information are different.

[0043] In some possible implementations, the bracket is strip-shaped, and along its length, the bracket includes a first end and a second end; the magnetic element includes a first magnetic element and a second magnetic element, with the first magnetic element disposed at the first end of the bracket and the second magnetic element disposed at the second end of the bracket; when the terminal charging system is in a second state, the magnetic induction sensor is closer to the first end of the bracket than the second end of the bracket; or when the terminal charging system is in a second state, the magnetic induction sensor is closer to the second end of the bracket than the first end of the bracket.

[0044] In this embodiment, the magnetic induction sensor is positioned near either the first or second end of the bracket when the terminal charging system is in the second state. It is understood that when the terminal charging system is in the second state, the magnetic induction sensor is further away from the first or second end of the bracket compared to the first state. Whether the terminal charging system is in the first state or the second state, the magnetic field information detected by the magnetic induction sensor for the first magnetic element is different, or the magnetic field information detected by the magnetic induction sensor for the second magnetic element is different.

[0045] In this way, when the terminal charging system is in the first state, the magnetic induction sensor can send first detection information to the processor of the electronic device. The processor can then determine that the terminal charging system is in the first state based on this first detection information and send first control information to the charging dock. When charging the electronic device, the charging dock can control the output power to the first output power based on the first control information.

[0046] When the terminal charging system is in the second state, the magnetic induction sensor can send second detection information to the processor of the electronic device. The processor can then determine that the terminal charging system is in the second state based on this second detection information and send second control information to the charging dock. When charging the electronic device, the charging dock can control the output power to the second output power based on the second control information.

[0047] In some possible implementations, the projection along the thickness direction of the electronic device results in the first and second projection areas of the first and second ends of the bracket on the electronic device, respectively. The magnetic induction sensor is located within or outside the first projection area, or within or outside the second projection area. In this way, when the terminal charging system is in a first state and a second state, the magnetic field information detected by the magnetic induction sensor differs significantly, thereby preventing the processor from incorrectly identifying the state of the terminal charging system.

[0048] In some possible implementations, the terminal charging system further includes a support housing, which is fitted onto the electronic device. The support housing includes a first region and a second region. The first region is positioned opposite the charging area of ​​the electronic device, and the second region is positioned opposite the non-charging area of ​​the electronic device. An active mechanism is located on the side of the support housing away from the electronic device and is connected to the support housing.

[0049] In this embodiment, the bracket housing can be fitted onto the electronic device to protect it in the event of a drop or collision. Furthermore, the bracket can be mounted on the bracket housing for easy disassembly.

[0050] In some possible implementations, the terminal charging system further includes a magnetic component and a magnetic induction sensor. The magnetic component is disposed on a bracket, and the magnetic induction sensor is disposed in a second region of the bracket housing. The electronic device includes a processor, which is communicatively connected to the magnetic induction sensor. The magnetic induction sensor is used to detect the magnetic field of the magnetic component and send detection information to the processor, wherein the detection information includes information about the magnetic field of the magnetic component. The processor is used to determine whether the terminal charging system is in a first state or a second state based on the detection information.

[0051] In this embodiment, the magnetic induction sensor is housed in the bracket housing, thus not occupying internal space of the electronic device. Furthermore, if the magnetic induction sensor is damaged, there is no need to repair or replace the electronic device, which helps reduce maintenance costs.

[0052] In some possible implementations, the terminal charging system also includes a magnetic chuck, which is disposed on the bracket housing and is used to attract the bracket in a first state and a second state.

[0053] In this embodiment, the magnetic attractor can be used to attract the holder when the terminal charging system is in the first state and the second state, which helps to ensure the stability of the terminal charging system in the first state and the second state. In some examples, the holder may include a magnetic material, and the magnetic attractor can directly attract the holder. In other examples, the magnetic attractor can attract magnetic components disposed on the holder, thereby attracting the holder. Attached Figure Description

[0081] The embodiments of this application are described below with reference to the accompanying drawings.

[0082] In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Movable connection" refers to a connection where the relative positional relationship can change after connection. "Rotary connection" refers to a connection where the two parts can rotate relative to each other after connection.

[0083] The directional terms mentioned in the embodiments of this application, such as "top," "bottom," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0084] In the embodiments of this application, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," and "third" may explicitly or implicitly include one or more of that feature.

[0085] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0086] References or "some embodiments" as described in this specification mean that one or more embodiments of this application include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, phrases such as "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiments, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0087] The terms “including,” “having,” and their variations all mean “including but not limited to,” unless otherwise specifically emphasized. The term “multiple” means at least two.

[0088] The terms "parallel" and "perpendicular" are relative to the current technological level, not absolute mathematical definitions.

Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, with the angle between them ranging from 80° to 100°.

[0089] It is understood that the specific embodiments described herein are merely illustrative of related embodiments and not intended to limit the scope of those embodiments. Furthermore, it should be noted that, for ease of description, only the parts relevant to the embodiments are shown in the accompanying drawings.

[0090] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0091] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0092] Please see Figure 1 , Figure 1 This is a schematic diagram of the terminal charging system 100 provided in this application in some embodiments.

[0093] In some embodiments, the terminal charging system 100 includes an electronic device 10 and a charging dock 20. The charging dock 20 is used for wireless charging of the electronic device 10. The working principle of wireless charging is the law of electromagnetic induction. In some examples, both the electronic device 10 and the charging dock 20 are provided with coils. The coil of the electronic device 10 is electrically connected to the battery of the electronic device 10. When the electronic device 10 is placed on the charging dock 20, the coil inside the electronic device 10 and the coil of the charging dock 20 induce an alternating magnetic field. After the coil of the electronic device 10 senses this magnetic field, it generates a current to charge the battery of the electronic device 10.

[0094] Please refer to the following: Figures 2A to 3 , Figure 2A yes Figure 1 The diagram shows a partial structural view of the terminal charging system 100 from another angle. Figure 2B yes Figure 2A The diagram shown is a structural schematic of the terminal charging system 100 in another state. Figure 3 yes Figure 2A The diagram shows a partial exploded view of the terminal charging system 100 in some embodiments.

[0095] In some embodiments, the terminal charging system 100 further includes a bracket 30, a movable mechanism 40, and a bracket housing 50. The bracket housing 50 can be fitted onto the electronic device 10 to protect the electronic device 10 in the event of a drop or collision. The movable mechanism 40 can be located on the side of the bracket housing 50 away from the electronic device 10. The movable mechanism 40 connects the bracket 30 and the bracket housing 50. The bracket 30 can be movably connected to the bracket housing 50 via the movable mechanism 40, thereby movably connecting to the electronic device 10. It is understood that the bracket 30 can be installed on the bracket housing 50 for easy removal.

[0096] The terminal charging system 100 may include a first state and a second state. For example, Figure 2A The terminal charging system 100 shown is in the first state. Figure 2B The terminal charging system 100 shown is in the second state. The bracket 30 can be rotated relative to the bracket housing 50 and the electronic device 10 via the movable mechanism 40, so that the terminal charging system 100 can switch between the first state and the second state.

[0097] Understandable, Figure 2A , Figure 2B , Figure 3 The accompanying drawings below only schematically illustrate some components included in the terminal charging system 100. The actual shape, size, location, and construction of these components are not subject to change. Figure 2A , Figure 2B , Figure 3 As well as the limitations of the accompanying figures below.

[0098] Please refer to the following: Figures 2B to 4 , Figure 4 yes Figure 3 The diagram shows a partial cross-sectional view of the electronic device 10 cut along point AA in some embodiments.

[0099] In some embodiments, the electronic device 10 can be a mobile phone (including candybar and foldable phones), a tablet computer, a personal digital assistant (PDA), etc. This application uses a mobile phone as an example for illustration. Of course, other types of electronic devices 10 can also adopt a similar structure, which will not be elaborated on later. For ease of description, for example, the length direction of the electronic device 10 is defined as the X-axis direction, the width direction as the Y-axis direction, and the height direction as the Z-axis direction. Among them, the X-axis, Y-axis, and Z-axis are mutually perpendicular. It can be understood that the coordinate system of the electronic device 10 can also be flexibly set according to specific needs.

[0100] For example, the electronic device 10 may include a housing 11 and a screen 12. The screen 12 may be located on one side of the housing 11 and fixedly connected to the housing 11. The screen 12 and the housing 11 may both extend into the internal space 13 of the electronic device 10. It is understood that the internal space 13 of the electronic device 10 may be used to accommodate internal components of the electronic device 10, such as speakers, microphones, batteries, camera modules, etc. For example, the bracket shell 50 may be fitted onto the housing 11 of the electronic device 10. Both the bracket shell 50 and the bracket 30 may be located on the side of the housing 11 away from the screen 12. When the charging dock 20 wirelessly charges the electronic device 10, the bracket 30 may be located between the electronic device 10 and the charging dock 20.

[0101] For example, the electronic device 10 may include a charging area 101 and a non-charging area 102. For example, Figures 2A to 3 The charging area 101 of the electronic device 10 is schematically delineated using dashed boxes. The charging area 101 and the non-charging area 102 of the electronic device 10 do not overlap, but overlap between their edges is permitted. It is understood that the area on the electronic device 10 excluding the charging area 101 constitutes the non-charging area 102. For example, the coil of the electronic device 10 can be located within the charging area 101. The charging base 20 can charge the electronic device 10 through the charging area 101. It is understood that the position, shape, and area of ​​the charging area 101 and the non-charging area 102 of the electronic device 10 can be adjusted as needed. The position, shape, and area of ​​the charging area 101 and the non-charging area 102 of the electronic device 10 are not subject to... Figures 2A to 3 Restricted.

[0102] like Figure 2AAs shown, when the terminal charging system 100 is in the first state, the entire bracket 30 is positioned opposite to the non-charging area 102 of the electronic device 10. At this time, the bracket 30 can also be positioned opposite to the second area 502 of the bracket housing 50. It can be understood that when the terminal charging system 100 is in the first state, the bracket 30 is not opposite to the charging area 101 of the electronic device 10. Figure 2B As shown, when the terminal charging system 100 is in the second state, at least a portion of the bracket 30 is positioned opposite to the charging area 101 of the electronic device 10. At this time, at least a portion of the bracket 30 can be positioned opposite to the first region 501 of the bracket housing 50. It is understood that the bracket 30 can be entirely positioned opposite to the charging area 101 of the electronic device 10, or it can be partially positioned opposite to the charging area 101 of the electronic device 10. In this embodiment, a portion of the bracket 30 is positioned opposite to the charging area 101 of the electronic device 10.

[0103] In some embodiments, when the charging dock 20 wirelessly charges the electronic device 10 and the terminal charging system 100 is in a first state, the output power of the charging dock 20 is a first output power. When the charging dock 20 wirelessly charges the electronic device 10 and the terminal charging system 100 is in a second state, the output power of the charging dock 20 is a second output power. The second output power is less than the first output power.

[0104] It is understandable that when the charging dock 20 wirelessly charges the electronic device 10 and the terminal charging system 100 is in the second state, at least a portion of the bracket 30 is located between the coil of the electronic device 10 and the coil of the charging dock 20. If the wireless charging power is high at this time, a strong alternating magnetic field will be generated between the coil of the charging dock 20 and the coil of the electronic device 10. Under the influence of the magnetic field, the metal on the bracket 30 will generate eddy current losses and hysteresis losses, and heat up, causing overheating during charging. Therefore, this application reduces the output power of the charging dock 20 when charging the electronic device 10, thereby reducing the eddy current losses and hysteresis losses generated by the bracket 30 under the influence of the magnetic field, thus reducing the heat generation problem of the bracket 30 and avoiding overheating of the bracket 30 when charging the electronic device 10. When the charging dock 20 wirelessly charges the electronic device 10 and the terminal charging system 100 is in the first state, the entire bracket 30 can be located offset between the coil of the electronic device 10 and the coil of the charging dock 20, and the bracket is less affected by the magnetic field during charging of the electronic device 10. Therefore, the charging dock 20 can output a large power to the electronic device 10, so that the electronic device 10 can be charged with high power to improve charging efficiency.

[0105] In this embodiment, the electronic device 10 may include a processor (not shown). The processor may be installed in the internal space 13 of the electronic device 10. The processor may be used to communicate with the charging dock 20. When the charging dock 20 wirelessly charges the electronic device 10, the processor may be used to control the output power of the charging dock 20. For example, when the charging dock 20 wirelessly charges the electronic device 10 and the terminal charging system 100 is in a second state, the processor may control the output power of the charging dock 20 to decrease. As another example, when the charging dock 20 wirelessly charges the electronic device 10 and the terminal charging system 100 is in a first state, the processor may control the output power of the charging dock 20 to increase.

[0106] Please continue reading. Figures 2A to 3 In some embodiments, the support housing 50 may include a first region 501 and a second region 502. Figures 2A to 3 The first region 501 is schematically defined using dashed boxes. For example, the first region 501 of the bracket housing 50 is positioned opposite the charging area 101 of the electronic device 10, and the second region 502 is positioned opposite the non-charging area 102 of the electronic device 10. It is understood that the first region 501 of the bracket housing 50 is projected along the target direction to obtain projection A, and the charging area 101 of the electronic device 10 is projected along the target direction to obtain projection B. Projections A and B can at least largely overlap. In some embodiments, this substantial overlap can be any of the following: projection A is completely located within projection B; or projection B is completely located within projection A; or projections A and B intersect each other, and the intersection area of ​​projections A and B accounts for more than 50% of projection A or projection B. Similarly, the second region 502 of the bracket housing 50 is projected along the target direction to obtain projection C, and the non-charging area 102 of the electronic device 10 is projected along the target direction to obtain projection D. Projections C and D can at least largely overlap.

[0107] like Figure 2A As shown, when the terminal charging system 100 is in the first state, the bracket 30 can be positioned opposite to the second region 502 of the bracket housing 50. Figure 2B As shown, when the terminal charging system 100 is in the second state, at least a portion of the bracket 30 is positioned opposite to the charging area 101 of the electronic device 10. At this time, at least a portion of the bracket 30 can be positioned opposite to the first region 501 of the bracket housing 50.

[0108] For example, the first region 501 can be generally circular. In other examples, the first region 501 may also be located at other positions on the support housing 50. The shape of the first region 501 may also be square or other shapes. It is understood that the position, shape, and area of ​​the first region 501 and the second region 502 can be adjusted as needed. The position, shape, and area of ​​the first region 501 and the second region 502 are not subject to... Figures 2A to 4 Restricted.

[0109] In the above embodiments, the bracket 30, the movable mechanism 40, and the bracket housing 50 can constitute the bracket housing 50. In some other embodiments, the terminal charging system 100 may not include the bracket housing 50. In this case, the movable mechanism 40 connects the electronic device 10 and the bracket 30. It is understood that the bracket 30 can be movably connected to the electronic device 10 via the movable mechanism 40. The bracket 30 can rotate relative to the electronic device 10 via the movable mechanism 40, so that the terminal charging system 100 can switch between a first state and a second state.

[0110] Please see Figure 5A , Figure 5A yes Figure 2A The terminal charging system 100 shown is a top view of its structure in some embodiments.

[0111] In some embodiments, the support 30 may be generally strip-shaped. Along its length, the support 30 may include a first end 31 and a second end 32. Exemplarily, the first end 31 and the second end 32 may be the two ends furthest apart on the support 30. In other examples, the support 30 may also be elliptical or other shapes, which are not strictly limited in this application.

[0112] For example, projecting along the Z-axis direction (i.e., the thickness direction of the electronic device 10), the projection area of ​​the first end 31 of the bracket 30 on the electronic device 10 is the first projection area 301, and the projection area of ​​the second end 32 on the electronic device 10 is the second projection area 302. For example, Figure 5A The first projection area 301 and the second projection area 302 are schematically represented by diagonal lines.

[0113] When the terminal charging system 100 is in the first state, the first end 31 and the second end 32 of the bracket 30 are both positioned opposite to the non-charging area 102 of the electronic device 10. At this time, the first end 31 and the second end 32 of the bracket 30 are both positioned opposite to the second region 502 of the bracket housing 50. For example, the length direction of the bracket 30 can be parallel to the Y-axis direction (i.e., the width direction of the electronic device 10). The length direction of the bracket 30 is the direction from the first end 31 to the second end 32. This direction from the first end 31 to the second end 32 can be referred to as the first direction. The first direction can be parallel to the width direction of the electronic device 10.

[0114] In this embodiment, when the terminal charging system 100 is in the first state, by setting the first end 31 and the second end 32 of the bracket 30 to be opposite to the non-charging area 102 of the electronic device 10, the bracket 30 can be prevented from being opposite to the charging area 101 of the electronic device 10, that is, the bracket 30 is prevented from intruding into the charging area 101 of the electronic device 10, thereby reducing the risk of the bracket 30 overheating due to heat generation.

[0115] Please continue reading. Figure 5A In some embodiments, the terminal charging system 100 may include a magnetic component 60 and a magnetic induction sensor 70. The magnetic component 60 may be disposed on the bracket 30. The magnetic component 60 may be a magnet, or it may be a magnetically conductive steel sheet, nanocrystals, etc.

[0116] The magnetic sensor 70 can be located in the non-charging area 102 of the electronic device 10. For example, the magnetic sensor can be installed in the internal space 13 of the electronic device 10 and electrically connected to the processor of the electronic device 10. This allows for fast response between the magnetic sensor and the processor of the electronic device 10.

[0117] The magnetic induction sensor 70 is used to detect the magnetic field of the magnetic component 60 and send detection information to the processor of the electronic device 10. The processor determines whether the terminal charging system 100 is in a first state or a second state based on the detection information. The detection information may include information about the magnetic field of the magnetic component 60. For example, the detection information may include the magnitude and polarity of the magnetic field of the magnetic component 60. It is understood that the magnetic induction sensor 70 can be used to detect the magnetic field of the magnetic component 60 when it is near the magnetic induction sensor. For example, the magnetic induction sensor 70 may be a Hall sensor, a magnetometer, or other device capable of sensing magnetic fields.

[0118] In this embodiment, the state of the terminal charging system 100, i.e., the state of the bracket 30, can be identified through the cooperation of the magnetic induction sensor 70 and the magnetic component 60, and the output power of the charging base 20 can be controlled according to the state of the bracket 30. The terminal charging system 100 has a simple structure, and the method for identifying the state of the terminal charging system 100 and controlling the charging power is relatively simple and flexible.

[0119] In some examples, the magnetic induction sensor 70 can be used to detect the magnitude of the magnetic field of the magnetic component 60. The processor can determine the magnitude of the magnetic field of the magnetic component 60 based on the detection information transmitted by the magnetic induction sensor 70. When the magnetic field of the magnetic component 60 is greater than or equal to a preset value, the terminal charging system 100 is determined to be in a first state; otherwise, the terminal charging system 100 is determined to be in a second state. Alternatively, the processor can determine the magnitude of the magnetic field of the magnetic component 60 based on the detection information transmitted by the magnetic induction sensor 70. When the magnetic field of the magnetic component 60 is greater than or equal to a preset value, the terminal charging system 100 is determined to be in a second state; otherwise, the terminal charging system 100 is determined to be in a first state.

[0120] For example, the magnetic element 60 may include a first magnetic element 61 and a second magnetic element 62. The first magnetic element 61 may be disposed at a first end 31 of the bracket 30. The second magnetic element 62 may be disposed at a second end 32 of the bracket 30.

[0121] In some examples, when the terminal charging system 100 is in the first state, the magnetic induction sensor 70 is closer to the first end 31 of the bracket 30 than to the second end 32 of the bracket 30. For example, the magnetic induction sensor 70 may be located on the periphery of the first projection area 301 of the bracket 30. The magnetic induction sensor 70 can detect the magnetic field of the first magnetic element 61 and send detection information to the processor. At this time, the processor can determine that the terminal charging system 100 is in the first state based on the detection information and send information to the charging base 20 (see [link]). Figure 1 The charging base 20 sends first control information. Based on this first control information, the charging base 20 adjusts its output power to the first output power. Thus, when the terminal charging system 100 is in the first state, the electronic device 10 can perform high-power charging, improving charging efficiency.

[0122] In other examples, when the terminal charging system 100 is in the first state, the magnetic induction sensor 70 is closer to the second end 32 of the bracket 30 than the first end 31 of the bracket 30. At this time, the magnetic induction sensor 70 can be located within or around the second projection area 302 of the bracket 30. The magnetic induction sensor 70 can detect the magnetic field of the second magnetic element 62 and send detection information to the processor. The processor can then determine that the terminal charging system 100 is in the first state based on the detection information and send first control information to the charging base 20. The charging base 20 adjusts its output power to the first output power according to the first control information.

[0123] In some examples, the magnetic induction sensor 70 can be used to detect the magnitude of the magnetic field of the magnetic component 60. When the terminal charging system 100 is in the first state, the magnetic induction sensor 70 is away from the first magnetic component 61 and the second magnetic component 62, and the magnetic field of the magnetic component 60 detected by the magnetic induction sensor 70 is less than a preset value (including the case where the detected magnetic field is zero, that is, the magnetic induction sensor 70 cannot detect the magnetic field of the magnetic component 60). The processor determines whether the terminal charging system 100 is in the first state or the second state based on the detection information of the magnetic induction sensor 70.

[0124] Please see Figure 5B , Figure 5B yes Figure 5A The terminal charging system 100 shown is a top view of its structure in some other embodiments. Figure 5B The terminal charging system 100 shown is Figure 5A The technical solutions of the terminal charging system 100 shown are largely the same, with the following differences:

[0125] When the terminal charging system 100 is in the first state, the magnetic induction sensor 70 can be located within the first projection area 301 of the bracket 30. The magnetic induction sensor 70 can detect the magnetic field of the first magnetic component 61 and send first detection information to the processor of the electronic device 10. At this time, the processor can determine that the terminal charging system 100 is in the first state based on the first detection information and send first control information to the charging base 20. When charging the electronic device 10, the charging base 20 adjusts the output power to the first output power according to the first control information. The first detection information includes information about the magnetic field of the first magnetic component 61.

[0126] In other examples, when the terminal charging system 100 is in the first state, the magnetic induction sensor 70 can be located within the second projection area 302 of the bracket 30. The magnetic induction sensor 70 can detect the magnetic field of the second magnetic element 62 and send first detection information to the processor of the electronic device 10. At this time, the processor can determine that the terminal charging system 100 is in the first state based on the first detection information and send first control information to the charging base 20. When charging the electronic device 10, the charging base 20 adjusts the output power to the first output power according to the first control information. The first detection information includes information about the magnetic field of the second magnetic element 62.

[0127] Please see Figure 6 , Figure 6 yes Figure 5A The terminal charging system 100 shown is a top view of its structure in another state.

[0128] In some embodiments, when the terminal charging system 100 is in the second state, the first end 31 or the second end 32 of the bracket 30 is disposed opposite to the charging area 101 of the electronic device 10. At this time, the first end 31 or the second end 32 of the bracket 30 is disposed opposite to the first region 501 of the bracket housing 50.

[0129] In this embodiment, when the terminal charging system 100 is in the second state, by setting the end of the bracket 30 to be opposite to the charging area 101 of the electronic device 10, the portion of the bracket 30 that is opposite to the charging area 101 of the electronic device 10 can be reduced, that is, the portion of the bracket 30 that intrudes into the charging area 101 of the electronic device 10 can be reduced, thereby reducing the risk of the bracket 30 overheating or overheating due to the magnetic field of the electronic device 10 during charging.

[0130] In this embodiment, when the terminal charging system 100 is in the second state, the first end 31 or the second end 32 of the bracket 30 is located in the charging area 101 of the electronic device 10. The direction from the first end 31 of the bracket 30 to the second end 32 is the second direction. The second direction is set at an angle to the first direction (that is, the direction from the first end 31 of the bracket 30 to the second end 32 when the terminal charging system 100 is in the first state).

[0131] It is understood that in this embodiment, the bracket 30 can rotate relative to the electronic device by a certain angle around a rotation center (e.g., the rotation axis of the movable mechanism 40), so that the length direction of the bracket 30 switches from the first direction to the second direction, or from the second direction to the first direction. In other words, the bracket 30 can rotate relative to the electronic device 10 by a certain angle around a rotation center (e.g., the rotation axis of the movable mechanism 40), so that the terminal charging system 100 switches from the first state to the second state, or from the second state to the first state. The way the terminal charging system 100 switches between the first state and the second state is relatively simple.

[0132] For example, the second direction may be parallel to the length direction of the electronic device 10. The second direction (that is, the direction in which the first end 31 of the bracket 30 points to the second end 32 when the terminal charging system 100 is in the second state) is perpendicular to the first direction (that is, the direction in which the first end 31 of the bracket 30 points to the second end 32 when the terminal charging system 100 is in the first state).

[0133] It is understandable that when the terminal charging system 100 is in the first state, the bracket 30 can be in a horizontal state, and when the terminal charging system 100 is in the first state, the bracket 30 can be in a vertical state. When the electronic device 10 is charging, the bracket 30 can rotate relative to the electronic device 10 to switch the terminal charging system 100 to the second state, that is, switch the bracket 30 to a horizontal state. In this way, when the terminal charging system 100 is in the first state, the bracket 30 can avoid the charging area 101 of the electronic device 10 to the greatest extent, reducing the influence of the magnetic field of the charging area 101 of the electronic device 10 on the bracket 30 during charging.

[0134] In some embodiments, when the terminal charging system 100 is in the second state, the magnetic induction sensor 70 can detect the magnetic field of the magnetic component 60 and send second detection information to the processor of the electronic device 10. The processor can determine that the terminal charging system 100 is in the second state based on the second detection information and send second control information to the charging base 20. When charging the electronic device 10, the charging base 20 can adjust the output power to a second output power based on the second control information. In this way, when the terminal charging system 100 is in the second state, the electronic device 10 can use a smaller power to charge, thereby reducing the eddy current loss and hysteresis loss generated by the bracket 30 under the influence of the magnetic field, thus reducing the heat generation problem of the bracket 30 and avoiding charging overheating. The second detection information includes information about the magnetic field of the magnetic component 60, and the second detection information is different from the first detection information.

[0135] In some examples, the magnetic induction sensor 70 can be used to detect the magnitude of the magnetic field of the magnetic component 60. When the terminal charging system 100 is in the second state, the magnetic induction sensor 70 is close to the first magnetic component 61 or the second magnetic component 62, and the magnetic induction sensor 70 detects that the magnetic field of the magnetic component 60 is greater than or equal to a preset value. The processor determines that the terminal charging system 100 is in the second state based on the second detection information from the magnetic induction sensor 70.

[0136] Understandable, Figure 5A The terminal charging system 100 shown is in the first state. Figure 6 The terminal charging system 100 shown is in the second state. During the transition from the first state to the second state, the positions of the first end 31 and the second end 32 of the bracket 30 relative to the electronic device 10 change, while the position of the magnetic induction sensor 70 remains unchanged. Therefore, Figure 6 The position of the magnetic induction sensor 70 of the terminal charging system 100 on the electronic device 10 is related to... Figure 5A The magnetic induction sensor 70 of the terminal charging system 100 shown is located on the electronic device 10.

[0137] In this embodiment, the magnetic induction sensor 70 is positioned near the first end 31 (or second end 32) of the bracket 30 when the terminal charging system 100 is in the first state. It is understood that when the terminal charging system 100 is in the second state, the magnetic induction sensor 70 is further away from the first end 31 (or second end 32) of the bracket 30 compared to the first state. The magnetic field information detected by the magnetic induction sensor 70 for the first magnetic element 61 (or second magnetic element 62) differs between the first and second states. For example, the magnetic induction sensor 70 can detect the magnitude of the magnetic field of the first magnetic element 61 (or second magnetic element 62). When the terminal charging system 100 is in the first state, the magnetic field detected by the magnetic induction sensor 70 for the first magnetic element 61 (or second magnetic element 62) is greater than or equal to a preset value; when the terminal charging system 100 is in the second state, the magnetic field detected by the magnetic induction sensor 70 for the first magnetic element 61 (or second magnetic element 62) is less than the preset value (including the case where the detected magnetic field is zero, i.e., the magnetic field of the first magnetic element 61 (or second magnetic element 62) cannot be detected).

[0138] In this way, when the terminal charging system 100 is in the first state, the magnetic induction sensor 70 can send first detection information to the processor of the electronic device 10. The processor of the electronic device 10 can then determine that the terminal charging system 100 is in the first state based on the first detection information and send first control information to the charging dock 20. When charging the electronic device 10, the charging dock 20 can control the output power to the first output power based on the first control information.

[0139] When the terminal charging system 100 is in the second state, the magnetic induction sensor 70 can send second detection information to the processor of the electronic device 10. The processor of the electronic device 10 can then determine that the terminal charging system 100 is in the second state based on the second detection information and send second control information to the charging dock 20. When charging the electronic device 10, the charging dock 20 can control the output power to the second output power based on the second control information.

[0140] In some other implementations, the terminal charging system 100 may not include the second magnetic element 62. In this case, the magnetic induction sensor 70 can be used to detect the magnetic field of the first magnetic element 61 and send detection information to the processor. The processor can then determine whether the terminal charging system 100 is in a first state or a second state based on the detection information.

[0141] Please continue reading. Figure 5A and Figure 6 In some embodiments, the terminal charging system 100 may further include a magnetic element 80. The magnetic element 80 may be disposed on the bracket housing 50. The magnetic element 80 can be used to attract the bracket 30 when the terminal charging system 100 is in a first state and a second state, which helps to ensure the stability of the terminal charging system 100 in the first state and the second state. In some examples, the bracket 30 may include a magnetic material, and the magnetic element 80 can directly attract the bracket 30. In other examples, the magnetic element 80 can attract magnetic elements disposed on the bracket 30, thereby attracting the bracket 30.

[0142] Please see Figure 7 , Figure 7 yes Figure 5A The terminal charging system 100 shown is a top view of its structure in some other embodiments. Figure 7 The terminal charging system 100 shown is Figure 5A The technical solutions of the terminal charging system 100 shown are largely the same, with the following differences:

[0143] In some embodiments, the number of magnetic induction sensors 70 can be multiple. For example, when the terminal charging system 100 is in a first state, at least one magnetic induction sensor 70 can be located on the periphery of the first projection area 301 to detect the magnetic field of the first magnetic element 61. At least one magnetic induction sensor 70 can be located on the periphery of the second projection area 302 to detect the magnetic field of the second magnetic element 62.

[0144] In some other embodiments, at least one magnetic sensor 70 may also be located within the first projection area 301 for detecting the magnetic field of the first magnetic element 61. At least one magnetic sensor 70 may also be located within the second projection area 302 for detecting the magnetic field of the second magnetic element 62.

[0145] In the above embodiments, by setting the relative position of the magnetic induction sensor 70 and the bracket 30, the magnetic induction sensor 70 detects the magnetic field of the first magnetic element 61 and / or the second magnetic element 62 when the terminal charging system 100 is in the first state, and does not detect the magnetic field of the first magnetic element 61 and the second magnetic element 62 when the terminal charging system 100 is in the second state.

[0146] Please see Figure 8A , Figure 8A yes Figure 2A The terminal charging system 100 shown is a top view of its structure in some other embodiments. Figure 8A The terminal charging system 100 shown includes Figure 6 The following describes most of the technical features of the terminal charging system 100. The main difference between the two technical solutions of the terminal charging system 100 will not be repeated.

[0147] In some embodiments, when the terminal charging system 100 is in the second state, the magnetic induction sensor 70 is closer to the second end 32 of the bracket 30 than the first end 31 of the bracket 30. Exemplarily, the magnetic induction sensor 70 may be located within or around the second projection area 302 of the bracket 30. In this case, the magnetic induction sensor 70 may be located around the second projection area 302 of the bracket 30. The magnetic induction sensor 70 can detect the magnetic field of the second magnetic element 62 and send second detection information to the processor. The processor can then determine that the terminal charging system 100 is in the second state based on the second detection information and send second control information to the charging base 20. When charging the electronic device 10, the charging base 20 can adjust the output power to the second output power based on the second control information. Thus, when the terminal charging system 100 is in the second state, the electronic device 10 can use a smaller power for charging, reducing eddy current losses and hysteresis losses generated by the bracket 30 under the influence of the magnetic field, thereby reducing the heat generation problem of the bracket 30 and avoiding overheating during charging.

[0148] In other examples, when the terminal charging system 100 is in the second state, the magnetic induction sensor 70 is closer to the first end 31 of the bracket 30 than to the second end 32 of the bracket 30. Exemplarily, the magnetic induction sensor 70 may be located within or around the first projection area 301 of the bracket 30. In this case, the magnetic induction sensor 70 can detect the magnetic field of the first magnetic element 61 and send second detection information to the processor. The processor can then determine that the terminal charging system 100 is in the second state based on the second detection information and send information to the charging base 20 (see [link]). Figure 1The second control information is sent. When charging the electronic device 10, the charging base 20 can adjust its output power to a second output power according to the second control information. In this way, when the terminal charging system 100 is in the second state, the electronic device 10 can use a smaller power to charge, thereby reducing the eddy current loss and hysteresis loss generated by the bracket 30 under the influence of the magnetic field, thus reducing the heat generation problem of the bracket 30 and avoiding the problem of charging overheating.

[0149] In some examples, the magnetic induction sensor 70 can be used to detect the magnitude of the magnetic field of the magnetic component 60. When the terminal charging system 100 is in the second state, the magnetic induction sensor 70 is close to the first magnetic component 61 or the second magnetic component 62, and the magnetic induction sensor 70 detects that the magnetic field of the magnetic component 60 is greater than or equal to a preset value. The processor determines that the terminal charging system 100 is in the second state based on the second detection information from the magnetic induction sensor 70.

[0150] Please see Figure 8B , Figure 8B yes Figure 8A The terminal charging system 100 shown is a top view of its structure in some other embodiments.

[0151] In some embodiments, when the terminal charging system 100 is in the second state, the magnetic induction sensor 70 may be located within the second projection area 302 of the bracket 30. The magnetic induction sensor 70 may be used to detect the magnetic field of the second magnetic component 62 and send second detection information to the processor. At this time, the processor may be used to determine that the terminal charging system 100 is in the second state based on the second detection information.

[0152] In other examples, the magnetic induction sensor 70 may be located within the first projection area 301 of the bracket 30. The magnetic induction sensor 70 can be used to detect the magnetic field of the first magnetic element 61 and send second detection information to the processor. In this case, the processor can determine that the terminal charging system 100 is in a second state based on the second detection information.

[0153] In some other embodiments, the terminal charging system 100 may not include the second magnetic element 62. In this case, the magnetic induction sensor 70 detects the magnetic field of the first magnetic element 61 and sends detection information to the processor. The processor determines that the terminal charging system 100 is in a second state based on the detection information and sends second control information to the charging base 20. When charging the electronic device 10, the charging base 20 can adjust the output power to a second output power according to the second control information. In this way, when the terminal charging system 100 is in the second state, the electronic device 10 can use a smaller power to charge, thereby reducing the eddy current loss and hysteresis loss generated by the bracket 30 under the influence of the magnetic field, thus reducing the heat generation problem of the bracket 30 and avoiding charging overheating.

[0154] In some embodiments, when the processor determines that the terminal charging system 100 is in the second state, it can also remind the user to rotate the bracket 30 through the software of the electronic device 10 so that the terminal charging system 100 switches to the first state.

[0155] Please see Figure 9 , Figure 9 yes Figure 8A The terminal charging system 100 shown is a top view of its structure in another state.

[0156] In some embodiments, when the terminal charging system 100 is in a first state, the magnetic induction sensor 70 can detect the magnetic field of the magnetic component 60 and send first detection information to the processor of the electronic device 10. The processor can determine that the terminal charging system 100 is in the first state based on the first detection information and send first control information to the charging dock 20. When charging the electronic device 10, the charging dock 20 can adjust its output power to a first output power based on the first control information. In this way, when the terminal charging system 100 is in the first state, the electronic device 10 can perform high-power charging, improving charging efficiency.

[0157] In some examples, the magnetic induction sensor 70 can be used to detect the magnitude of the magnetic field of the magnetic component 60. When the terminal charging system 100 is in the first state, the magnetic induction sensor 70 is away from the first magnetic component 61 and the second magnetic component 62, and the magnetic field of the magnetic component 60 detected by the magnetic induction sensor 70 is less than a preset value (including the case where the detected magnetic field is zero, that is, the magnetic induction sensor 70 cannot detect the magnetic field of the magnetic component 60). The processor determines that the terminal charging system 100 is in the first state based on the first detection information of the magnetic induction sensor 70.

[0158] Understandable, Figure 8A The terminal charging system 100 shown is in the second state. Figure 9 The terminal charging system 100 shown is in a first state. During the transition from the second state to the first state, the positions of the first end 31 and the second end 32 of the bracket 30 relative to the electronic device 10 change, while the position of the magnetic induction sensor 70 remains unchanged. Therefore, Figure 9 The position of the magnetic induction sensor 70 of the terminal charging system 100 on the electronic device 10 is related to... Figure 8A The magnetic induction sensor 70 of the terminal charging system 100 shown is located on the electronic device 10.

[0159] Understandable, Figure 8A and Figure 9 The terminal charging system 100 shown is the same as the terminal charging system 100 in the previous embodiment (e.g.) Figure 5A and Figure 6The main difference of the terminal charging system 100 shown is that the relative positional relationship between the magnetic induction sensor 70 and the bracket 30 is different in different states.

[0160] It is understood that in the above embodiments, the magnetic induction sensor 70 can be an internal component of the electronic device 10, that is, the magnetic induction sensor 70 is part of the electronic device 10. In other embodiments, the magnetic induction sensor 70 may also be disposed in the bracket housing 50 (see [link to documentation]). Figure 5A The second region 502 of the bracket housing 50. In this case, the magnetic induction sensor 70 can be part of the bracket housing 50. The magnetic induction sensor 70 can communicate with the processor of the electronic device 10. When the magnetic induction sensor 70 is located in the second region 502 of the bracket housing 50, the relative positional relationship between the magnetic induction sensor 70 and the bracket 30 can be referred to the above. Figures 5A to 9 The relevant descriptions will not be repeated here. By placing the magnetic induction sensor 70 in the bracket housing 50, it does not occupy the internal space of the electronic device 10. Furthermore, if the magnetic induction sensor 70 is damaged, there is no need to repair or replace the electronic device 10, which helps to reduce maintenance costs.

[0161] Please refer to the following: Figures 10 to 12 , Figure 10 yes Figure 3 The schematic diagram of the active mechanism 40 shown in some embodiments is shown. Figure 11 yes Figure 10 The diagram shown is a partial exploded view of the active mechanism 40 in some embodiments. Figure 12 yes Figure 2A The terminal charging system 100 shown is a schematic diagram of a partial cross-sectional structure cut along BB in some embodiments.

[0162] In some embodiments, the active mechanism 40 may be connected to the support housing 50, thereby connecting the electronic device 10 via the support housing 50. In other embodiments, the active mechanism 40 may not include the support housing 50, and the active mechanism 40 may be directly connected to the electronic device 10.

[0163] For example, the active mechanism 40 may include a first connector 41, a second connector 42, and an elastic member 43. The first connector 41 can be fixedly connected to the bracket 30. The second connector 42 can be fixedly connected to the electronic device 10. For example, the second connector 42 can be fixedly connected to the bracket housing 50, thereby the second connector 42 can be fixedly connected to the electronic device 10 through the bracket housing 50.

[0164] The elastic element 43 can be located between the bracket 30 and the bracket housing 50, and abuts against both the bracket 30 and the bracket housing 50. The elastic element 43 has an elastic force on both the bracket 30 and the bracket housing 50, and this elastic force can cause the bracket 30 to tend to move away from the bracket housing 50 and the electronic device 10. The elastic element 43 can indirectly abut against the electronic device 10 by abutting against the bracket housing 50. In some embodiments, the terminal charging system 100 may not include the bracket housing 50, in which case the elastic element 43 can directly abut against the electronic device 10, for example, the elastic element 43 can abut against the electronic device 10.

[0165] In some other embodiments, the rotating structure may not include the elastic element 43.

[0166] The above text, with reference to the accompanying drawings, describes the connection relationships of the active mechanism 40. The following text, with reference to the accompanying drawings, describes the specific structure of the active mechanism 40.

[0167] Please refer to the following: Figure 11 and Figure 13 , Figure 13 yes Figure 11 The top view of the first connector 41 shown.

[0168] In some embodiments, the first connector 41 may include a first body 411, a first limiting block 412, and a second limiting block 413. For example, the first body 411 may include a first top surface 4111, a first bottom surface 4112, and an outer surface 4113. The first top surface 4111 and the first bottom surface 4112 are disposed facing away from each other. The outer surface 4113 connects the first top surface 4111 and the first bottom surface 4112. For example, both the first limiting block 412 and the second limiting block 413 protrude from the outer surface 4113 of the first body 411 and are spaced apart.

[0169] For example, the perpendicular segment L3 from the center of the first limiting block 412 to the central axis 410 of the first connector 41 is perpendicular to the perpendicular segment L4 from the center of the second limiting block 413 to the central axis 410 of the first connector 41.

[0170] For example, there can be two first limiting blocks 412. The two first limiting blocks 412 are located on opposite sides of the first body 411. For example, the line connecting the two first limiting blocks 412 can pass through the center of the first body 411.

[0171] For example, there can be two second limiting blocks 413. The two second limiting blocks 413 are located on opposite sides of the first body 411. For example, the line connecting the two second limiting blocks 413 can pass through the center of the first body 411.

[0172] For example, two first limiting blocks 412 and two second limiting blocks 413 can be arranged around the central axis 410 of the first body 411, and the first limiting blocks 412 and the second limiting blocks 413 can be distributed alternately.

[0173] In some embodiments, the first connector 41 may be provided with a receiving groove 414, the opening of which may be located on the first bottom surface 4112 of the first body 411. In this case, the first connector 41 may be a hollow structure. In some examples, the receiving groove 414 may penetrate through the first body 411, for example, the receiving groove 414 may penetrate through the first top surface 4111 and the first bottom surface 4112. In other examples, the receiving groove 414 may not penetrate through the first top surface 4111.

[0174] In some other embodiments, the first connector 41 may also be cylindrical or other shapes, which are not strictly limited in this application.

[0175] Please refer to the following: Figures 14 to 16 , Figure 14 yes Figure 11 The diagram shows the structure of the second connector 42 from another angle. Figure 15 yes Figure 14 The diagram shows the structure of the second connector 42 from another angle. Figure 16 yes Figure 15 The diagram shows a partial cross-sectional view of the second connector 42 cut along CC.

[0176] In some embodiments, the second connector 42 may be a hollow structure. For example, the second connector 42 may include a second body 421, a first limiting groove 422, and a second limiting groove 423. The second body 421 may include a second top surface 4211, a second bottom surface 4212, and an inner surface 4213. The second top surface 4211 and the second bottom surface 4212 are disposed opposite to each other. The inner surface 4213 connects between the first top surface 4111 and the first bottom surface 4112. The openings of both the first limiting groove 422 and the second limiting groove 423 are located on the inner surface 4213 of the second body 421. For example, the first limiting groove 422 may communicate with the second limiting groove 423.

[0177] Please refer to the following: Figure 16 and Figure 17 , Figure 17 yes Figure 11 The second connector 42 shown is a top view of the structure in some embodiments.

[0178] In some embodiments, the first limiting groove 422 may include a first side 4221, a second side 4222, and a third side 4223 connected in sequence. The second limiting groove 423 may include a first side 4231, a second side 4232, and a third side 4233 connected in sequence. For example, the first side 4221 of the first limiting groove 422 may be connected to the third side 4233 of the second limiting groove 423, and the first side 4231 of the second limiting groove 423 may be connected to the third side 4223 of the first limiting groove 422.

[0179] In some embodiments, the perpendicular segment L5 from the center of the first limiting groove 422 to the central axis 420 of the second connector 42 forms an angle with the perpendicular segment L6 from the center of the second limiting groove 423 to the central axis 420 of the second connector 42. It can be understood that the center of the first limiting groove 422 can be the center of the first side 4221, the second side 4222, and the third side 4223 of the first limiting groove 422. In other words, the distances from the center of the first limiting groove 422 to the first side 4221, the second side 4222, and the third side 4223 of the first limiting groove 422 are equal. The center of the second limiting groove 423 can be the center of the first side 4231, the second side 4232, and the third side 4233 of the second limiting groove 423. In other words, the distances from the center of the second limiting groove 423 to the first side 4231, the second side 4232, and the third side 4233 of the second limiting groove 423 are equal.

[0180] For example, the perpendicular segment L5 from the center of the first limiting groove 422 to the central axis 420 of the second connector 42 is perpendicular to the perpendicular segment L6 from the center of the second limiting groove 423 to the central axis 420 of the second connector 42.

[0181] For example, there may be two first limiting slots 422. The two first limiting slots 422 are arranged opposite to each other. For example, the line connecting the two first limiting slots 422 may pass through the center of the second body 421.

[0182] For example, there may be two second limiting slots 423. The two second limiting slots 423 are arranged opposite to each other. For example, the line connecting the two second limiting slots 423 may pass through the center of the second body 421.

[0183] For example, two first limiting grooves 422 and two second limiting grooves 423 can be arranged around the central axis 420 of the second body 421, and the first limiting grooves 422 and the second limiting grooves 423 can be alternately distributed.

[0184] Please refer to the following: Figure 18 and Figure 19 , Figure 18 yes Figure 3The diagram shown is a partial structural schematic of the terminal charging system 100 in some embodiments. Figure 19 yes Figure 18 This is a schematic diagram of the assembly structure of a portion of the terminal charging system 100. For example, Figure 19 This diagram mainly illustrates the assembly structure of the electronic device 10, the bracket 30, the movable mechanism 40, and the bracket housing 50. For example, Figure 19 The diagram illustrates the structure of the terminal charging system 100 in multiple states. Figure 19 The terminal charging system 100 shown in (a) is in the first state. Figure 19 The terminals shown in (b), (c), and (d) are in a state between the first and second states. Figure 19 The terminal charging system 100 shown in (e) is in the second state. It can be understood that the terminal charging system 100 can... Figure 19 The state shown in (a) in the diagram is sequentially processed through... Figure 19 The states shown in (b), (c), and (d) transition to... Figure 19 The state shown in (e) is as follows.

[0185] In some embodiments, the included angles between the second side 4222 of the first limiting groove 422 and the first side 4221 and the third side 4223 can all be obtuse angles. For example, the included angle between the second side 4222 and the first side 4221 of the first limiting groove 422 is equal to the included angle between the second side 4222 and the third side 4223.

[0186] In this embodiment, the structure of the second limiting groove 423 is similar to or the same as the structure of the first limiting groove 422. For details regarding the structure of the second limiting groove 423, please refer to the relevant description of the first limiting groove 422; it will not be repeated here. For example, the structure of the second limiting groove 423 may be the same as the structure of the first limiting groove 422, but slight structural differences between the second limiting groove 423 and the first limiting groove 422 are permissible. In other embodiments, the structure of the second limiting groove 423 may also differ from the structure of the first limiting groove 422.

[0187] like Figure 19As shown in (a), in some embodiments, the second connector 42 may be fitted over the first connector 41. Exemplarily, the second body 421 may surround the first limiting block 412 and the second limiting block 413. When the terminal charging system 100 is in the first state, the first limiting block 412 may be located within the first limiting groove 422, that is, the first limiting block 412 may be located between the first side 4221, the second side 4222, and the third side 4223 of the first limiting groove 422. The second limiting block 413 may be located within the second limiting groove 423, that is, the second limiting block 413 may be located between the first side 4231, the second side 4232, and the third side 4233 of the second limiting groove 423. In this embodiment, the structure of the movable mechanism 40 is relatively simple, and the thickness of the movable mechanism 40 in its axial direction (that is, the thickness direction of the terminal charging system 100) can be reduced, which is beneficial to the thinning of the movable mechanism 40 and the terminal charging system 100.

[0188] It is understood that in this application, one of the first connecting member 41 and the second connecting member 42 is provided with a first limiting block 412, and the other is provided with a first limiting groove 422 and a second limiting groove 423. In the above embodiment, the first connecting member 41 is provided with a limiting block, and the second connecting member 42 is provided with a limiting groove. In some other embodiments, the positions of the limiting block and the limiting groove can also be interchanged. That is, the first connecting member 41 can be provided with a limiting groove, and the second connecting member 42 can be provided with a limiting block.

[0189] In some embodiments, the elastic element 43 can be a spring. One end of the elastic element 43 can abut against the bracket 30, and the other end abuts against the bracket housing 50. At this time, the first limiting block 412 can abut against the second side 4222 of the first limiting groove 422 under the elastic force of the elastic element 43, and the second limiting block 413 can abut against the second side 4232 of the second limiting groove 423 under the elastic force of the elastic element 43. In this embodiment, through the mutual cooperation of the elastic element 43, the first limiting groove 422, and the second limiting groove 423, the movement of the first limiting block 412 and the second limiting block 413 can be restricted. At this time, the bracket 30 is less likely to move relative to the electronic device 10 under the elastic force of the elastic element 43, which is beneficial to ensuring the stability of the terminal charging system 100 in the first state and the second state. In other examples, the first limiting block 412 can also abut against the first side 4221 and / or the third side 4223 of the first limiting groove 422. The second limiting block 413 can also abut against the first side 4231 and / or the third side 4233 of the second limiting groove 423.

[0190] It should be understood that in this embodiment, the other end of the elastic member 43 can indirectly abut against the electronic device 10 by abutting against the bracket housing 50. In other embodiments, the terminal charging system 100 may not include the bracket housing 50, in which case the other end of the elastic member 43 can directly abut against the electronic device 10. For example, the first end 431 and the second end 432 of the elastic member 43 can directly abut against the electronic device 10.

[0191] For example, a portion of the elastic element 43 may be located within the receiving groove 414 of the first connector 41. This reduces the thickness of the movable mechanism 40 in the Z-axis direction, thereby reducing the thickness of the terminal charging system 100 in the Z-axis direction, which is beneficial for a thinner design.

[0192] It should be understood that in this embodiment, the receiving groove 414 can penetrate the first connecting member 41, in which case one end of the elastic member 43 can pass through the first connecting member 41 and directly abut against the bracket 30. In other embodiments, the receiving groove 414 may not penetrate the first connecting member 41, in which case one end of the elastic member 43 can abut against the bottom wall of the receiving groove 414, thereby indirectly abutting against the bracket 30.

[0193] Please see Figure 19 In some embodiments, the bracket 30 can be rotatably connected to the electronic device 10 via the first connector 41 and the second connector 42. During the transition of the terminal charging system 100 from the first state to the second state, the first connector 41 can rotate relative to the second connector 42 about the rotation axis 401 of the movable mechanism 40, while moving along the thickness direction of the electronic device 10. The rotation axis 401 of the movable mechanism 40 can pass through the center of the first connector 41 and the second connector 42. For example, the rotation axis 401 of the movable mechanism 40 can coincide with the central axis 410 of the first connector 41 and the central axis 420 of the second connector 42.

[0194] like Figure 19As shown in (e), when the terminal charging system 100 is in the second state, the first limiting block 412 can be located within the second limiting groove 423, and under the elastic force of the elastic member 43, the first limiting block 412 can abut against the second side 4232 of the second limiting groove 423. The second limiting block 413 can be located within the first limiting groove 422, and under the elastic force of the elastic member 43, the second limiting block 413 can abut against the second side 4222 of the first limiting groove 422. Through the mutual cooperation of the elastic member 43, the first limiting groove 422, and the second limiting groove 423, the movement of the first limiting block 412 and the second limiting block 413 can be restricted, which helps to ensure the stability of the terminal charging system 100 in the second state. In some other examples, the first limiting block 412 can also abut against the first side 4221 and / or the third side 4223 of the first limiting groove 422. The second limiting block 413 can also abut against the first side 4231 and / or the third side 4233 of the second limiting groove 423. In other examples, when the terminal charging system 100 is in the second state, the first limiting block 412 can also abut against the first side 4231 and / or the third side 4233 of the second limiting groove 423, and the second limiting block 413 can also abut against the first side 4221 and / or the third side 4223 of the first limiting groove 422.

[0195] During the transition from the first state to the second state of the terminal charging system 100, both the first limiting block 412 and the second limiting block 413 can rotate around the rotation axis 401 of the movable mechanism 40, and simultaneously move along the thickness direction of the electronic device 10. The first limiting block 412 can move from the first limiting groove 422 to the second limiting groove 423, and the second limiting block 413 can move from the second limiting groove 423 to the first limiting groove 422. In this embodiment, the transition of the bracket 30 between the first state and the second state is achieved through the cooperation of the first limiting block 412 with the first limiting groove 422 and the second limiting groove 423, and the cooperation of the second limiting block 413 with the first limiting groove 422 and the second limiting groove 423. The structure of the movable mechanism 40 is relatively simple, and the transition of the bracket 30 is relatively convenient.

[0196] Furthermore, by setting two limiting blocks (including the first limiting block 412 and the second limiting block 413) to cooperate with the first limiting groove 422 and the second limiting groove 423, the first connecting member 41 is less likely to tilt during rotation relative to the second connecting member 42, which helps to improve the stability of the first connecting member 41 during rotation relative to the second connecting member 42, thereby improving the stability of the bracket 30 during rotation. In some other embodiments, the first connecting member 41 may not include the second limiting block 413.

[0197] like Figure 19As shown in (a), (b), and (c), the first limiting block 412 can move along the third side 4223 of the first limiting groove 422, and the second limiting block 413 can move along the third side 4233 of the second limiting groove 423. During this process, both the first limiting block 412 and the second limiting block 413 can rotate counterclockwise around the rotation axis 401 of the movable mechanism 40. The bracket 30 can further compress the elastic member 43 and move closer to the bracket housing 50 (i.e., closer to the electronic device 10) along the thickness direction of the electronic device 10.

[0198] like Figure 19 As shown in (c), (d), and (e), the first limiting block 412 can move from the first limiting groove 422 to the second limiting groove 423, and under the action of the elastic force of the elastic member 43, it moves along the first side 4231 of the second limiting groove 423 until it abuts against the second side 4232 of the second limiting groove 423. The second limiting block 413 can move from the second limiting groove 423 to the first limiting groove 422, and under the action of the elastic force of the elastic member 43, it moves along the first side 4221 of the first limiting groove 422 until it abuts against the second side 4222 of the first limiting groove 422. During this process, both the first limiting block 412 and the second limiting block 413 can rotate counterclockwise around the rotation axis 401 of the movable mechanism 40. The bracket 30 approaches the bracket shell 50 (i.e., approaches the electronic device 10) along the thickness direction of the electronic device 10.

[0199] It is understood that, in this application, during the transition of the terminal charging system 100 from the first state to the second state, the first limiting block 412 and the second limiting block 413 can also rotate clockwise around the rotation axis 401 of the movable mechanism 40.

[0200] In this embodiment, by setting the included angle between the second side 4222 and the third side 4223 of the first limiting groove 422 to be obtuse, the transition between the second side 4222 and the third side 4223 of the first limiting groove 422 is relatively smooth, which helps to reduce the resistance when the first limiting block 412 moves. As a result, the first limiting block 412 can move more smoothly along the third side 4223 of the first limiting groove 422 to the first side 4231 of the second limiting groove 423, so as to realize the transition of the terminal charging system from the first state to the second state. Similarly, by setting the included angle between the second side 4232 and the third side 4233 of the second limiting groove 423 to an obtuse angle, the transition between the second side 4232 and the third side 4233 of the second limiting groove 423 is relatively smooth, which helps to reduce the resistance when the second limiting block 413 moves. This allows the second limiting block 413 to move more smoothly along the third side 4233 of the second limiting groove 423 to the first side 4221 of the first limiting groove 422, thus realizing the transition of the terminal charging system from the first state to the second state. It is understood that in this embodiment, by setting the structure of the first limiting groove 422 and the second limiting groove 423, the rotation of the bracket 30 relative to the electronic device 10 is more convenient. The user can rotate the bracket 30 without pressing it.

[0201] Furthermore, in this embodiment, by setting the angle between the second side 4222 and the first side 4221 of the first limiting groove 422 to an obtuse angle, and the angle between the second side 4232 and the first side 4231 of the second limiting groove 423 to an obtuse angle, the first limiting block 412 and the second limiting block 413 can also rotate clockwise around the rotation axis 401 of the movable mechanism 40. That is, the first limiting block 412 can also move along the first side 4221 of the first limiting groove 422 to the third side 4233 of the second limiting groove 423, and the second limiting block 413 can also move along the first side 4231 of the second limiting groove 423 to the third side 4223 of the first limiting groove 422, so as to realize the conversion of the terminal charging system 100 from the first state to the second state. In this embodiment, the rotation mode of the bracket 30 is relatively flexible.

[0202] Furthermore, in this embodiment, the lengths of the first side 4221 of the first limiting groove 422 and the first side 4231 of the second limiting groove 423 can be set to be smaller, so as to reduce the movement length of the first limiting block 412 and the second limiting block 413.

[0203] Please see Figure 20 , Figure 20 yes Figure 3 The diagram shows a bottom view of the structure of the active mechanism 40 in some embodiments.

[0204] In some embodiments, the perpendicular segment from the center of the first limiting groove 422 to the rotation axis 401 of the movable mechanism 40 is the first perpendicular segment. The perpendicular segment from the center of the second limiting groove 423 to the rotation axis of the movable mechanism 40 is the second perpendicular segment. The second perpendicular segment is perpendicular to the first perpendicular segment. In this embodiment, the perpendicular segment from the center of the first limiting groove 422 to the central axis of the second connector 42 (see [reference]) Figure 17 The vertical segment coincides with the first vertical line segment. The vertical line segment from the center of the second limiting groove 423 to the center axis of the second connector 42 (see [reference]). Figure 17 It coincides with the second perpendicular segment.

[0205] It is understood that when the electronic device 10 is charging, the first limiting block 412 can move from the first limiting groove 422 to the second limiting groove 423, and the second limiting block 413 can move from the second limiting groove 423 to the first limiting groove 422. In this embodiment, by limiting the relative positions of the first limiting groove 422 and the second limiting groove 423, when the first limiting block 412 moves from the first limiting groove 422 to the second limiting groove 423, the first connecting member 41 can rotate 90 degrees or 270 degrees relative to the second connecting member 42, thereby allowing the bracket 30 to avoid the charging area 101 of the electronic device 10 as much as possible, reducing the influence of the magnetic field of the charging area 101 of the electronic device 10 on the bracket 30 during charging. For example, when the terminal charging system 100 is in the second state (e.g. Figure 6 As shown), the direction from the first end 31 to the second end 32 of the bracket 30 can be parallel to the length direction of the electronic device 10, and either the first end 31 or the second end 32 of the bracket 30 is located in the charging area 101 of the electronic device 10. By making the first vertical segment perpendicular to the second vertical segment, the bracket 30 can rotate 90 degrees clockwise or 270 degrees counterclockwise around the rotation axis 401 of the movable mechanism 40, so that the terminal charging system 100 can switch from the second state to the first state, and when the terminal charging system 100 is in the first state (e.g., Figure 5A As shown, the direction from the first end 31 of the bracket 30 to the second end 32 can be parallel to the width direction of the electronic device 10. In this way, when the terminal charging system 100 is in the first state, the bracket 30 can avoid the charging area 101 of the electronic device 10 to the greatest extent, and reduce the influence of the magnetic field of the charging area 101 of the electronic device 10 on the bracket 30 during charging.

[0206] Furthermore, by setting two first limiting grooves 422 and two second limiting grooves 423, the first limiting grooves 422 and the second limiting grooves 423 can be arranged alternately around the rotation axis 401 of the movable mechanism 40, allowing the first connecting member 41 to rotate 90 degrees, 180 degrees, 270 degrees, or 360 degrees clockwise or counterclockwise relative to the second connecting member 42. This, in turn, causes the bracket 30 to rotate 90 degrees, 180 degrees, 270 degrees, or 360 degrees clockwise or counterclockwise around the rotation axis 401 of the movable mechanism 40. The rotation mode of the bracket is quite flexible.

[0207] In some embodiments, the movable mechanism 40 is disposed opposite to the non-charging area 102 of the electronic device 10. This prevents the movable mechanism 40 from encroaching on the charging area 101 of the electronic device 10. Furthermore, since the bracket 30 is rotatably connected to the electronic device 10 via the movable mechanism 40, the first end 31 and the second end 32 of the bracket 30 can rotate about the rotation axis 401 of the movable mechanism 40. By misaligning the movable mechanism 40 with the charging area 101 of the electronic device 10, it can be ensured that the portion of the electronic device 10 connected to the movable mechanism on the bracket can avoid the charging area 101 of the electronic device 10 during charging.

[0208] Please refer to the following: Figure 21 and Figure 22 , Figure 21 yes Figure 3 The schematic diagram shown is a partial structural diagram of the terminal charging system 100 in some other embodiments. Figure 22 yes Figure 21 The diagram shows a partial assembly structure of the terminal charging system 100. Figure 21 and Figure 22 The terminal charging system 100 shown includes Figure 18 and Figure 19 The following describes most of the technical features of the terminal charging system 100. The main difference between the two technical solutions of the terminal charging system 100 will not be repeated.

[0209] In some embodiments, the elastic member 43 may be a spring sheet. The elastic member 43 may include a first end 431, a second end 432, and a middle portion 433. The middle portion 433 of the elastic member 43 is located between the first end 431 and the second end 432, and connects the first end 431 and the second end 432.

[0210] For example, the middle portion 433 of the elastic element 43 can be curved. The middle portion 433 of the elastic element 43 can abut against the bracket 30. The first end 431 and the second end 432 can both abut against the bracket housing 50. Compared with the spring solution, the elastic sheet does not need to reserve a large compression length, thereby reducing the thickness of the movable mechanism 40 in the Z-axis direction, and further reducing the thickness of the terminal charging system 100 in the Z-axis direction, which is beneficial for a thinner design.

[0211] It should be understood that in this embodiment, the first end 431 and the second end 432 of the elastic member 43 can indirectly abut against the electronic device 10 by abutting against the bracket housing 50. In other embodiments, the terminal charging system 100 may not include the bracket housing 50, in which case the first end 431 and the second end 432 of the elastic member 43 can directly abut against the electronic device 10. For example, the first end 431 and the second end 432 of the elastic member 43 can directly abut against the electronic device 10.

[0212] Please see Figure 23 , Figure 23 yes Figure 3 The diagram shows a partial structural representation of the terminal charging system 100 in some other embodiments. Exemplary, Figure 23 The diagram mainly illustrates the assembly structure of the electronic device 10, the bracket 30, the movable mechanism 40, and the bracket housing 50. Figure 23 The diagram illustrates the structure of the terminal charging system 100 in multiple states. Figure 23 The terminal charging system 100 shown in (a) is in the first state. Figure 23 The terminals shown in (b) and (c) are in a state between the first state and the second state. Figure 23 The terminal charging system 100 shown in (d) is in the second state. It can be understood that the terminal charging system 100 can... Figure 23 The state shown in (a) in the diagram is sequentially processed through... Figure 23 The states shown in (b) and (c) are transitioned to Figure 23 The state shown in (d) is shown in the diagram.

[0213] Figure 23 The terminal charging system 100 shown may include Figure 18 and Figure 19 Most of the technical features of the terminal charging system 100 shown are as follows: Figure 23 The main difference between the terminal charging system 100 shown and the terminal charging system 100 in the previous embodiment is that the structure of the limiting groove of the active mechanism 40 is different. The other contents of this embodiment can be referred to the previous embodiment, and will not be repeated here.

[0214] In some embodiments, the first limiting groove 422 may include a first side 4221, a second side 4222, and a third side 4223 connected in sequence. The included angle between the second side 4222 and the first side 4221 of the first limiting groove 422 may be an obtuse angle. The included angle between the second side 4222 and the third side 4223 of the first limiting groove 422 may be an acute angle or a right angle.

[0215] For example, the first limiting groove 422 may include a first side 4231, a second side 4232, and a third side 4233 connected in sequence. The structure of the second limiting groove 423 is similar to or the same as the structure of the first limiting groove 422. For details on the structure of the second limiting groove 423, please refer to the relevant description of the first limiting groove 422; it will not be repeated here. For example, the structure of the second limiting groove 423 may be the same as the structure of the first limiting groove 422, but slight structural differences between the second limiting groove 423 and the first limiting groove 422 are permissible. In other embodiments, the structure of the second limiting groove 423 may also differ from the structure of the first limiting groove 422.

[0216] like Figure 23 As shown in (a), when the terminal charging system 100 is in the first state, the first limiting block 412 can abut against the second side 4222 and the third side 4223 of the first limiting groove 422 under the elastic force of the elastic member 43, and the second limiting block 413 can abut against the second side 4232 and the third side 4233 of the second limiting groove 423 under the elastic force of the elastic member 43. In other examples, when the terminal charging system 100 is in the first state, the first limiting block 412 can also abut against the second side 4222 of the first limiting groove 422, and the second limiting block 413 can also abut against the second side 4232 of the second limiting groove 423.

[0217] like Figure 23 As shown in (d), when the terminal charging system 100 is in the second state, the first limiting block 412 can abut against the second side 4232 and the third side 4233 of the second limiting groove 423 under the elastic force of the elastic member 43, and the second limiting block 413 can abut against the second side 4222 and the third side 4223 of the first limiting groove 422 under the elastic force of the elastic member 43. In some other examples, when the terminal charging system 100 is in the second state, the first limiting block 412 can also abut against the second side 4232 of the second limiting groove 423, and the second limiting block 413 can also abut against the second side 4222 of the first limiting groove 422.

[0218] like Figure 23As shown in (a) and (b), during the transition of the terminal charging system 100 from the first state to the second state, the user can first press the bracket 30, which further compresses the elastic member 43 and moves closer to the bracket shell 50 (i.e., closer to the electronic device 10) along the thickness direction of the electronic device 10. The first limiting block 412 no longer abuts against the second side 4222 of the first limiting groove 422, and the second limiting block 413 no longer abuts against the second side 4232 of the second limiting groove 423.

[0219] like Figure 23 As shown in (b), (c), and (d), when the first limiting block 412 crosses the third side 4223 of the first limiting groove 422 and the second limiting block 413 crosses the third side 4233 of the second limiting groove 423, both the first limiting block 412 and the second limiting block 413 can rotate counterclockwise around the rotation axis 401 of the movable mechanism 40. Thus, the first limiting block 412 moves to the second limiting groove 423 and, under the action of the elastic force of the elastic member 43, moves along the first side 4231 of the second limiting groove 423 until it abuts against the second side 4232 of the second limiting groove 423; the second limiting block 413 can move to the first limiting groove 422 and, under the action of the elastic force of the elastic member 43, moves along the first side 4221 of the first limiting groove 422 until it abuts against the second side 4222 of the first limiting groove 422. During this process, the bracket 30 approaches the bracket housing 50 (that is, approaches the electronic device 10) along the thickness direction of the electronic device 10.

[0220] In this embodiment, by setting the included angle between the second side 4222 and the third side 4223 of the first limiting groove 422 to an acute angle or a right angle, when the terminal charging system 100 is in the first state, the third side 4223 of the first limiting groove 422 can effectively restrict the rotation of the first limiting block 412, which is beneficial to improving the stability of the terminal charging system 100 in the first state. When the terminal charging system 100 is in the second state, the third side 4223 of the first limiting groove 422 can effectively restrict the rotation of the second limiting block 413, which is beneficial to improving the stability of the terminal charging system 100 in the second state. Similarly, by setting the included angle between the second side 4232 and the third side 4233 of the second limiting groove 423 to an acute angle or a right angle, the third side 4233 of the second limiting groove 423 can effectively restrict the rotation of the first limiting block 412 or the second limiting block 413, which is beneficial to improving the stability of the terminal charging system 100 in both the first and second states.

[0221] Furthermore, in this embodiment, by setting the angle between the second side 4222 and the first side 4221 of the first limiting groove 422 to an obtuse angle, and the angle between the second side 4232 and the first side 4231 of the second limiting groove 423 to an obtuse angle, the first limiting block 412 and the second limiting block 413 can also rotate clockwise around the rotation axis 401 of the movable mechanism 40. That is, the first limiting block 412 can also move along the first side 4221 of the first limiting groove 422 to the third side 4233 of the second limiting groove 423, and the second limiting block 413 can also move along the first side 4231 of the second limiting groove 423 to the third side 4223 of the first limiting groove 422, so as to realize the conversion of the terminal charging system 100 from the first state to the second state. In this embodiment, the rotation mode of the bracket 30 is relatively flexible.

[0222] It is understood that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0223] The above are merely some embodiments of this application, and the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
