In the embodiments of the present application, it is to be understood that references to directional terms, such as "upper", "lower", "left", "right", "inner", "outer", etc., are merely with reference to the orientation of the drawings, and thus, the use of directional terms is intended to better and more clearly illustrate and understand the embodiments of the present application, rather than to indicate or imply that the devices or elements being referred to must have a particular orientation, be constructed and operate in a particular orientation, and therefore, should not be construed as limiting the embodiments of the present application.

In the present embodiments, the terms "first," "second," "third," "fourth" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", "a third" and a fourth "may explicitly or implicitly include one or more such feature.

In the present embodiments, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.

In the embodiment of the present application, "and/or" is merely an association relationship describing an association object, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

In the embodiment of the present application, it should be noted that "vertical" and "parallel" are respectively indicated as being substantially vertical and substantially parallel within a range allowing an error, and the error range may be a range in which an angle of deviation is less than or equal to 5 °, 8 °, or 10 ° with respect to absolute vertical and absolute parallel, respectively, and are not particularly limited herein.

Electronic devices often need to be charged to ensure that they have sufficient power. The traditional charging mode of electronic equipment is that the output end of the charging wire is inserted into a charging interface of the electronic equipment to charge the electronic equipment, and when people use the electronic equipment while charging, the charging wire can cause interference to people. Thus, charging devices having either a vertical charging base or a cradle-type charging base are emerging on the market.

Whether the charging base is a vertical charging base or a horizontal charging base, the charging base is usually placed on a desktop or ground, and therefore, the charging base generally comprises a base for being placed on the desktop or ground, a supporting member connected to the base and used for supporting the electronic device, and a charging member used for charging the electronic device. Therefore, the charging base is large in size, and the electronic equipment is inconvenient to charge through the charging base for outdoor activities or occasions such as the operation of taking the electronic equipment on hands.

After that, magnetic wireless charging base appears on the market again, is provided with magnet on the magnetic wireless charging base, through the magnet looks actuation that sets up in its with electronic equipment on the magnet to with the magnetic wireless charging base actuation of magnetic on electronic equipment, charge electronic equipment.

Like this, the wireless base that charges of magnetic attraction type only need set up charge part and magnet that charges to electronic equipment can reduce the volume of charging the base, so as to portable, and the base that charges can also be taken on hand together by people along with electronic equipment, in order to make things convenient for people to hold electronic equipment operation while charging.

However, for the above charging base (the vertical charging base, the horizontal charging base and the magnetic wireless charging base), if the quick charging requirement of the electronic device is to be met, a higher charging power needs to be set for the charging base, so that in the charging process of the electronic device, more heat is generated by the charging base and the electronic device, and therefore, the charging base needs to have a larger heat dissipation efficiency.

In the related art, the vertical charging base, the horizontal charging base and the magnetic wireless charging base are all radiating through the radiating fan. For the vertical charging base and the horizontal charging base, although the requirements of quick charging can be met, a heat dissipation fan with larger power and a heat dissipation air duct with larger diameter are required to be arranged so as to dissipate heat of the charging base and the heat dissipation fan, and thus the design requirements of miniaturization of the charging base are not facilitated.

For the magnetic wireless charging base, although the design requirement of miniaturization of the charging base can be met, the size of a heat dissipation channel and the power of a heat dissipation fan are limited due to the limitation of the space of the magnetic wireless charging base, so that the heat dissipation power is limited, and if the charging power of the magnetic wireless charging base is excessively large (more than 15W), the charging power of the magnetic wireless charging base on the market at present is generally between 5W and 15W), the phenomenon that the magnetic wireless charging base and electronic equipment are damaged due to unsmooth heat dissipation can occur.

Therefore, the charging base in the related art cannot satisfy both the requirement of rapid charging and the requirement of miniaturized design.

In addition, the heat dissipation fan dissipates heat of the electronic device through air flow, and the heat dissipation efficiency is limited by the air temperature and the air flow rate. The electronic equipment can generate more heat when being used in a charging state for a long time, and the phenomenon of untimely heat dissipation can occur to the electronic equipment through the heat dissipation fan, so that the problems of heating, clamping, frame rate reduction and the like of the electronic equipment can be caused, and the problem of inconvenient use of a user in the charging state can be caused.

After alternating current is supplied to the transmitting coil TX, an alternating magnetic field is generated around the transmitting coil TX, and magnetic induction lines of the magnetic field at least partially pass through the receiving coil RX, so that the receiving coil RX can induce alternating current according to the electromagnetic induction principle, and thus, electric energy is transmitted to the electronic device 12 through the transmitting coil TX and the receiving coil RX.

In addition, the second electric control board 1141 may be disposed in the power charger 111, and in this case, the first current conversion module may be disposed in the power charger 111 or in the first connector 114; in this arrangement, the current transmission process and the conversion process are the same as those when the second electric control board 1141 is disposed in the first connector 114, and will not be described herein.

The second electric control board 1141 and the first current conversion module may also be disposed within the charging base 113. At this time, the output terminal of the charging line 112 is electrically connected to the input terminal of the second electric control board 1141. The direct current output by the power charger 111 is transmitted to the charging wire 112 through the first connector 114, the charging wire 112 transmits the direct current to the second electric control board 1141, the second electric control board 1141 transmits the direct current to the first current conversion module, and the first current conversion module converts the direct current into alternating current and then transmits the alternating current to the transmitting coil TX.

In the above embodiment, the first connector 114 and the power charger 111 may be integrally connected or detachably connected. When the first connector 114 is detachably connected to the power charger 111, the first connector 114 and the power charger 111 may be connected through a USB interface, a lighting interface, or the like.

For example, referring to fig. 6, the first connector 114 and the power charger 111 are connected through a USB interface, which includes a female socket 1111 and a male socket 1142. The female socket 1111 is disposed at an output end of the power charger 111, the male socket 1142 is disposed on the first connector 114, and the male socket 1142 is electrically connected to an input end of the second electric control board 1141. When the electronic device 12 needs to be charged by using the charging device 11, the male socket 1142 may be plugged into the female socket 1111, so that the male socket 1142 and the female socket 1111 are electrically connected, and the input end of the second electronic control board 1141 is electrically connected to the power charger 111 through the male socket 1142 and the female socket 1111. Wherein, the USB interface can be Type-A interface, type-B interface or Type-C interface.

With continued reference to fig. 6, in order to reduce interference during the transmission of current from the USB interface to the second electronic control board 1141, the first connector 114 further includes a shielding metal cap 1143. Referring to fig. 7, fig. 7 is a schematic cross-sectional view of the shielding metal cover in fig. 5. The shield metal cap 1143 is formed with a shield cavity 1143A and first and second connection holes 1143B and 1143C communicating with the shield cavity 1143A.

The second electric control board 1141 is disposed in the shielding cavity 1143A, and a portion of the male housing 1142 passes through the first connecting hole 1143B and extends into the shielding cavity 1143A to be electrically connected to an input end of the second electric control board 1141, and another portion of the male housing 1142 is disposed outside the shielding cavity 1143A for connection with the female housing 1111. The input end of the charging wire 112 passes through the second connection hole 1143C and extends into the shielding cavity 1143A to be electrically connected to the output end of the second electric control board 1141.

In this way, in the process that the current is transmitted from the USB interface to the second electric control board 1141 and is transmitted to the charging wire 112 through the second electric control board 1141, other interference signals or electromagnetic waves outside the second interface can be shielded through the shielding metal cover 1143, so as to reduce interference suffered by the current, and thus, the current transmission is more stable.

Furthermore, the first connecting hole 1143B can also fix the male housing 1142. Specifically, the male socket 1142 may be in interference fit with the first connection hole 1143B, so that the male socket 1142 may be prevented from falling out of the first connection hole 1143B, so that the connection between the male socket 1142 and the second electronic control board 1141 may be more stable. The second connection hole 1143C also fixes the input terminal of the charging wire 112. Specifically, the input end of the charging wire 112 is in interference fit with the second connection hole 1143C, so that the charging wire 112 can be prevented from falling out of the second connection hole 1143C, and the connection between the charging wire 112 and the second electric control board 1141 can be more stable.

In addition, to protect the second electrical control plate 1141 and the shielding metal cap 1143, the first connector 114 also includes a plastic film 1144 and a housing 1145. The plastic film 1144 is disposed in the shielding cavity 1143A of the shielding metal housing 1143 and is wrapped around the second electric control plate 1141 for protecting the second electric control plate 1141. The housing 1145 forms a protective cavity in which the shield metal housing 1143 is located, so that the shield metal housing 1143 and the second electrical control plate 1141 are shielded by the housing 1145.

Wherein, the housing 1145 further has a first through hole and a second through hole formed thereon, which are in communication with the protection cavity. The first through hole is sleeved outside the first connecting hole 1143B, so that the male socket 1142 passes through the first connecting hole 1143B; the second through hole is sleeved outside the second connecting hole 1143C, so that the charging wire 112 passes through the second connecting hole 1143C.

The SR joint is a structure where the wire and the housing 1145 are connected, and is used to prevent the core wire inside and outside the wire from being broken when the wire is pulled. That is, in this embodiment, the SR connection is only used to fixedly connect the charging cord 112 with the charging base 113, and is not used for current transmission therebetween.

In other embodiments, the second connector 115 may also be provided with a metal connector based on the SR connector, and the connector is electrically connected to the output end of the charging wire 112. And an inner circumferential wall of the input connection hole 1132 is made of a metal material, and the inner circumferential wall of the input connection hole 1132 is electrically connected with the transmitting coil TX. At this time, by inserting the plug into the input connection hole 1132 and bringing the plug into contact with the inner peripheral wall of the input connection hole 1132, the output end of the charging wire 112 can be electrically connected to the transmitting coil TX through the plug and the input connection hole 1132.

The second sealing ring 116 is disposed at the input connection hole 1132 and is in sealing connection with the second connector 115 and the charging base 113. In some embodiments, the second sealing ring 116 is sleeved outside the second joint 115, and the inner peripheral wall of the second sealing ring 116 abuts against the second joint 115, at this time, after the second joint 115 is connected with the input connection hole 1132, the second sealing ring 116 may be located in the input connection hole 1132 and abuts against the inner peripheral wall of the input connection hole 1132, so as to realize sealing between the second joint 115 and the charging base 113; annular clamping grooves can be formed in the inner peripheral wall of the input connecting hole 1132, so that the part, away from the axis of the second sealing ring 116, of the second sealing ring is clamped in the annular clamping grooves, and the second connector 115 and the charging base 113 are sealed.

In other embodiments, a limiting boss is disposed at one end of the second connector 115 connected to the charging wire 112, the second sealing ring 116 is sleeved on the outer side of the second connector 115, and the inner peripheral wall of the second sealing ring 116 abuts against the second connector 115, after the second connector 115 is connected to the input connection hole 1132, the second sealing ring 116 is located between the outer side wall of the charging base 113 and the limiting boss, and abuts against the outer side wall of the charging base 113 and the limiting boss, so that the second connector 115 is sealed with the charging base 113.

The second connector 115 is in sealing connection with the charging base 113 through the second sealing ring 116, so that when the charging device 11 is used for charging the electronic equipment 12, impurities such as dust and the like can be prevented from entering the charging base 113 through the input connecting hole 1132 to influence the normal use of the charging base 113.

In addition, when the charging device 11 is used to charge the electronic device 12 in a wading environment such as a bathroom, a bath, or the like, the second seal ring 116 can also prevent water from entering the charging base 113 through the input connection hole 1132 to cause safety accidents such as electric shock or fire.

Referring to fig. 9 and 10, fig. 9 is a schematic diagram of an exploded structure of the charging base provided in some embodiments of the present application, and fig. 10 is a schematic diagram of a cross-sectional structure of the charging base according to fig. 9. The charging base 113 includes a thermally conductive housing 1133, a liquid cooled membrane 1134, and a drive member 1135. The heat-conducting housing 1133 is made of a heat-conducting material, for example, the heat-conducting housing 1133 may be made of copper, aluminum, zinc, silica gel, carbon fiber, polycarbonate, or the like. The heat conductive housing 1133 is capable of conducting heat to conduct heat generated by the charging base 113 to the outside of the heat conductive housing 1133.

With continued reference to fig. 10, a receiving cavity 1133A is formed in the thermally conductive housing 1133, and the thermally conductive housing 1133 has a first side wall 1133B and a second side wall 1133C disposed opposite each other. The second side wall 1133C is used to support the electronic device, i.e., the electronic device 12 may be in contact with the second side wall 1133C when the electronic device 12 is charged using the charging base 113.

The accommodating cavity 1133A is configured to accommodate the liquid cooling film 1134, the driving element 1135, and the like, and when the charging base 113 is a magnetic attraction charging or a charging seat charging by a wireless charging manner, the accommodating cavity 1133A is further configured to accommodate the transmitting coil TX; when the charging base 113 is a base charge charged by direct impact, the accommodating cavity 1133A is further configured to accommodate a portion of the charging wire 112 connected to the charging connector 1131.

The shape of the heat conductive housing 1133 includes, but is not limited to, a cylindrical shape, an elliptic cylindrical shape, a cubic shape, a rectangular parallelepiped shape, or an irregular shape. In the specific example shown in fig. 9 and 10, the thermally conductive housing 1133 is cylindrical.

With continued reference to fig. 9, the thermally conductive housing 1133 includes a first housing 1133D and a second housing 1133E. One of the first housing 1133D and the second housing 1133E is formed with a cavity with one side open, the other of the first housing 1133D and the second housing 1133E is located at the opening of the cavity, the opening of the cavity is blocked, and the cavity with the blocked opening forms the accommodating cavity 1133A. The first side wall 1133B may be a side wall of the first housing 1133D away from the second housing 1133E, where the second side wall 1133C is a side wall of the second housing 1133E away from the first housing 1133D; the first side wall 1133B may also be a side wall of the second housing 1133E away from the first housing 1133D, where the second side wall 1133C is a side wall of the first housing 1133D away from the second housing 1133E.

By providing the heat conductive housing 1133 as the first housing 1133D and the second housing 1133E, the first housing 1133D and the second housing 1133E may be separately processed to reduce the processing difficulty of the heat conductive housing 1133. In addition, by arranging the heat-conducting housing 1133 as the first housing 1133D and the second housing 1133E, the liquid cooling film 1134 and the driving member 1135 are further convenient to be installed in the accommodating cavity 1133A, so that the assembling difficulty of the charging base 113 is reduced. The first housing 1133D and the second housing 1133E may be connected by a clamping connection, a screwing connection, or the like.

On this basis, in order to improve the tightness after the first housing 1133D and the second housing 1133E are connected, please continue to refer to fig. 9, the heat-conducting housing 1133 further includes a first sealing ring 1133F. The axial direction of the first sealing ring 1133F is consistent with the axial direction of the opening of the cavity, and the first sealing ring 1133F is arranged at the opening of the cavity and is in sealing connection with the first shell 1133D and the second shell 1133E.

Specifically, the first seal ring 1133F may be abutted against both sides of the first housing 1133D and the second housing 1133E facing each other, that is, by disposing the first seal ring 1133F between the first housing 1133D and the second housing 1133E, the first seal ring 1133F is pressed by the first housing 1133D and the second housing 1133E to achieve sealing between the first housing 1133D and the second housing 1133E; the side surfaces of the first housing 1133D and the second housing 1133E facing each other may be provided with an annular sealing groove, and the axial direction of the sealing groove is consistent with the axial direction of the first sealing ring 1133F, so that a part of the first sealing ring 1133F facing the first housing 1133D is clamped into the sealing groove on the first housing 1133D, and a part of the first sealing ring 1133F facing the second housing 1133E is clamped into the sealing groove on the second housing 1133E, so as to realize sealing between the first housing 1133D and the second housing 1133E.

Impurities such as dust can be prevented from entering the accommodating cavity 1133A through the connecting part of the first shell 1133D and the second shell 1133E by the first sealing ring 1133F, so that the influence of the impurities such as dust on the components in the accommodating cavity 1133A can be avoided, and the charging base 113 can be ensured to be normally used. In addition, when the charging device 11 is used to charge the electronic device 12 in a wading environment such as a bathroom, a bath, or the like, the first seal ring 1133F can also prevent water from entering the housing cavity 1133A through the connection between the first housing 1133D and the second housing 1133E, thereby causing a safety accident such as an electric shock or fire.

The thickness direction of the liquid cooling film 1134 is consistent with the arrangement direction of the first side wall 1133B and the second side wall 1133C (direction X shown in fig. 9), and the liquid cooling film 1134 is disposed in the accommodating cavity 1133A and is in thermal conduction with the first side wall 1133B and the second side wall 1133C. Specifically, the liquid cooling film 1134 may be adhered to the first side wall 1133B by glue, or may be fixed to the first side wall 1133B by screwing or clamping, and the liquid cooling film 1134 may be directly adhered to the second side wall, or may contact with the second side wall by a heat conducting material. Note that, the liquid cooling film 1134 may be made of a heat conductive material, for example, the liquid cooling film 1134 may be made of a graphene heat conductive material, a silica gel heat conductive material, a polyimide material with high heat conductivity, or the like.

A liquid cooling flow channel is formed in the liquid cooling film 1134, and the liquid cooling flow channel is filled with cooling liquid; the driving member 1135 is disposed in the accommodating cavity 1133A, and is connected to the liquid cooling film 1134, for driving the cooling liquid in the liquid cooling film 1134 to flow. The cooling liquid can be water, mineral oil, heat conducting oil, graphene and the like.

When the charging device 11 is used to charge the electronic device 12, the electronic device 12 may be placed on the charging base 113 and the electronic device 12 is in contact with the second side wall 1133C, and since the liquid cooling film 1134 is in thermal conduction with the first side wall 1133B and the second side wall 1133C, during the charging process, heat generated by the electronic device 12 can be conducted to the liquid cooling film 1134 in the accommodating cavity 1133A through the second side wall 1133C, and the driving member 1135 can drive the cooling liquid in the liquid cooling film 1134 to circulate in the liquid cooling flow channel. In this way, the cooling liquid can continuously absorb the heat in the accommodating cavity 1133A (the heat generated by the charging base 113 and the heat conducted by the electronic device 12 to the liquid cooling film 1134) in the flowing process, and conduct the absorbed heat to the first side wall 1133B through the liquid cooling film 1134, and then dissipate the heat to the outside of the heat conducting housing 1133 through the first side wall 1133B, so that the heat can be dissipated to the electronic device 12 and the charging base 113 through the charging base 113.

Because the specific heat capacity of the liquid is larger, the liquid can absorb heat quickly and radiate the heat, and compared with the heat radiation of a heat radiation fan, the liquid cooling heat radiation has higher heat radiation efficiency. Therefore, the cooling liquid circularly flows in the cooling flow channel to dissipate heat of the electronic device 12, so that heat generated by the electronic device 12 can be rapidly dissipated to the outside of the heat conduction shell 1133, and the temperature of the electronic device 12 can be rapidly reduced, so that the problems of heat generation, clamping, frame rate reduction and the like of the electronic device 12 in a charging state in use are alleviated, and a user is facilitated to use the electronic device 12 in the charging state.

The cooling liquid can also absorb heat generated by the charging base 113 by circulating in the cooling flow passage, thereby dissipating heat from the charging base 113. In this way, the charging power of the charging base 113 can be set higher to meet the need for rapid charging of the electronic device 12.

Because the thickness of the liquid cooling film 1134 is smaller, the space of the accommodating cavity 1133A occupied by the liquid cooling film 1134 is smaller, so that the volume of the heat conducting shell 1133 can be reduced, and the volume of the charging base 113 can be further reduced, so as to meet the miniaturization requirement of people on the charging base 113.

In addition, compared with the sound generated when the cooling fan rotates, the sound of the cooling liquid flowing in the liquid cooling flow channel is smaller, so that the cooling liquid radiates heat to the charging base 113 and the electronic equipment 12, and noise generated in the use process of the charging base 113 can be reduced.

Wherein in some embodiments, the drive 1135 may be a micro water pump. The water inlet and the water outlet of the micro water pump are communicated with the liquid cooling flow channel, and after the micro water pump is powered, cooling liquid can be driven by the micro water pump to circularly flow between the liquid cooling flow channel and the micro water pump so as to dissipate heat of the charging base 113.

In other embodiments, referring to fig. 11, fig. 11 is a schematic diagram illustrating an exploded structure of a charging base according to some embodiments of the present application. The driving member 1135 may further include a vibrator 1135A and a first electronic control board 1135B. The first electronic control board 1135B is electrically connected to the vibrator 1135A, and the first electronic control board 1135B can control the vibrator 1135A to vibrate along the thickness direction of the liquid cooling film 1134. Vibrator 1135A is disposed between liquid cooling film 1134 and second sidewall 1133C and is in contact with liquid cooling film 1134. Therefore, in the process of vibrating the vibrator 1135A along the thickness direction of the liquid cooling film 1134, the vibrator 1135A can continuously strike or squeeze the liquid cooling film 1134, so as to drive the liquid cooling film 1134 to vibrate, and in the process of vibrating the vibrator 1135A to drive the liquid cooling film 1134, the cooling liquid in the liquid cooling flow channel can be continuously squeezed, so as to drive the cooling liquid to flow.

When the charging device 11 is used to charge the electronic device 12, current can be transmitted to the first electronic board 1135B through the charging device 11 and then transmitted to the vibrator 1135A through the first electronic board 1135B to supply power to the vibrator 1135A, so that the vibrator 1135A vibrates. In this way, vibrator 1135A may drive the coolant within liquid cooling film 1134 to flow within the cooling flow path to cool charging base 113 and electronic device 12.

Also, the vibration frequency of the vibrator may be controlled through the first electronic control board 1135B to adjust the vibration frequency of the vibrator according to the temperatures of the charging base 113 and the electronic device 12, thereby controlling the flow speed of the cooling liquid. In this way, when the temperature of the charging base 113 and the electronic device 12 is low, the vibration frequency of the vibrator 1135A can be reduced to reduce the noise of the vibrator 1135A, and the electric power consumed by the vibrator 1135A can be saved.

For example, the vibrator 1135A may be a mobile phone vibrator 1135A, where the mobile phone vibrator 1135A is a device that is applied to a mobile phone and vibrates the mobile phone in the case of a mobile phone call, incoming message, or alarm, etc. Specifically, the mobile phone vibrator 1135A includes a micro motor and a cam disposed on an output shaft of the micro motor, the first electric control board 1135B is electrically connected with the micro motor, and the cam is in contact with the liquid cooling film 1134. The first electric control board 1135B supplies power to the micro motor, and the micro motor drives the cam to rotate, so that the cam continuously impacts the liquid cooling film 1134 to drive the liquid cooling film 1134 to vibrate, and then the cooling liquid is driven to flow.

The vibrator 1135A may also be a piezoceramic vibrator 1135D, for example. When a voltage is applied to the piezoelectric ceramic in the piezoelectric ceramic vibrator 1135D after the piezoelectric ceramic vibrator 1135D is energized, the piezoelectric ceramic vibrates due to bending, so as to drive the liquid cooling film 1134 to vibrate, and further drive the cooling liquid to flow.

The piezoelectric ceramic vibrator 1135D may be connected to the first electronic control board 1135B through a flexible circuit board, and the piezoelectric ceramic vibrator 1135D may also be connected to the first electronic control board 1135B through a connection wire.

Because the volume of the piezoelectric ceramic vibrator 1135D is smaller, the space of the accommodating cavity 1133A occupied by the piezoelectric ceramic vibrator 1135D after being arranged in the accommodating cavity 1133A is smaller, so that the heat conducting shell 1133 can be arranged smaller, the volume of the charging base 113 can be further reduced, and the miniaturized design of the charging base 113 is facilitated.

It should be noted that, if the charging base 113 is a charging base that is charged by a direct charging manner, the output end of the charging wire 112 may be electrically connected to the charging connector 1131 through the first electric control board 1135B, so that the current transmitted by the charging wire 112 is transmitted to the charging connector 1131 through the first electric control board 1135B and then transmitted to the electronic device 12. Since the current transmitted by the charging wire 112 in this manner is direct current, it is necessary to convert the current supplied to the piezoelectric ceramic vibrator 1135D into alternating current.

If the charging base 113 is a magnetic charging or a wireless charging, the output end of the charging wire 112 may be electrically connected to the transmitting coil TX through the first electronic control board 1135B. At this time, since the voltage of the alternating current required for the transmitting coil TX and the voltage of the alternating current required for the piezoelectric ceramic vibrator 1135D may be different, the current supplied to the transmitting coil TX and the current supplied to the piezoelectric ceramic vibrator 1135D need to be converted, respectively.

In view of this, in some embodiments, referring to fig. 12, fig. 12 is a schematic diagram illustrating a connection relationship between a driving module and a charging line in the charging device shown in fig. 1. The drive 1135 also includes a drive module 1135C. An input of the driving module 1135C is electrically connected to an output of the charging line 112.

Referring to fig. 13 and 14, fig. 13 is an enlarged schematic view of the structure at B in fig. 12, and fig. 14 is an enlarged schematic view of the structure at C in fig. 12. The charging wire 112 includes seven connection wires, which are a first wire 1121, a second wire 1122, a third wire 1123, a fourth wire 1124, a fifth wire 1125, a sixth wire 1126, and a seventh wire 1127, respectively. The first line 1121 (analog power line) connects the VCC end of the driving module 1135C and the VCC end of the second electric control board 1141, the second line 1122 (digital power line) connects the VDDIO end of the driving module 1135C and the VDDIO end of the second electric control board 1141, the third line 1123 (data line) connects the SCL end of the driving module 1135C and the SCL end of the second electric control board 1141, and the fourth line 1124 (control line) connects the SDA end of the driving module 1135C and the SDA end of the second electric control board 1141.

The second electric control board 1141 is capable of transmitting direct current to the driving module 1135C through the first line 1121, the second line 1122, the third line 1123 and the fourth line 1124, and the driving module 1135C converts the direct current into alternating current according to the voltage requirement required by the piezoceramic vibrator 1135D (the voltage across which the piezoceramic vibrator 1135D vibrates is typically about 170V).

When the charging base 113 is a base charger charged by a direct charging method, the fifth line 1125 (power line), the sixth line 1126 (data line) and the seventh line 1127 (ground line) are all connected to the first electric control board 1135B and the second electric control board 1141, so as to transmit the direct current received by the second electric control board 1141 to the charging connector 1131 through the first electric control board 1135B. When the charging base 113 is in magnetic attraction charging or in wireless charging, the fifth line 1125 (power line), the sixth line 1126 (data line) and the seventh line 1127 (ground line) are all connected to the first current conversion module and the first electric control board 1135B, so as to transmit the alternating current converted by the first current conversion module to the transmitting coil TX through the first electric control board 1135B.
