Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

A charging system according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Fig. 1 is a schematic structural diagram of a charging system according to an embodiment of the present invention, and fig. 2 is a schematic mounting position diagram of a first limiting assembly according to an embodiment of the present invention; fig. 3 is a schematic structural diagram of a second electronic device according to an embodiment of the present invention. As shown in fig. 1 to 3, the charging system includes a first electronic device 1 and a second electronic device 2. The first electronic device 1 includes a decoration hole 11 and a charging contact 12, and the second electronic device 2 includes a device body and a charging contact 22; the charging contact 12 is arranged in the decorative hole 11; the charging connector 22 comprises a contact electrode 221, and the contact electrode 221 is movably connected inside the device body; in the case where the second electronic device 2 is charged through the decoration hole 11, the contact electrode 221 is in contact with the charging contact 12.

The first electronic device 1 may be one of electronic devices with relatively large battery capacity, such as a mobile phone, a tablet computer, an electronic book reader, an MP3 player, an MP4 player, a laptop portable computer, a vehicle-mounted computer, a desktop computer, a set-top box, and an intelligent television, and the second electronic device 2 may be one of intelligent wearable devices, such as an intelligent watch, an intelligent glasses, and an intelligent bracelet, which may establish an information interaction relationship with the first electronic device 1.

As shown in fig. 1, the side frame of the first electronic device 1 may include a sound outlet 13 and a USB (Universal Serial Bus) interface 14. The decoration hole 11 and the sound outlet hole 13 may be located on both sides of the USB interface 14, or may be located on the same side of the USB interface 14. Wherein, under the condition that the decoration hole 11 and the sound outlet hole 13 are symmetrically arranged, the decoration hole 11 can improve the aesthetic property of the first electronic device 1. Since the aperture of the decoration hole 11 is small, when the first electronic device 1 can charge through the decoration hole 11, the size of the adapted charging connector 22 is relatively small, which is beneficial for the first electronic device 1 to charge other second electronic devices 2 with small volume. Further, when the first electronic device 1 is equipped with a charging plug that also contacts the electrode 221, the first electronic device 1 can also be charged through the decorative hole 11. Based on this, a charging contact 12 may be provided in the decoration hole 11 for charging the first electronic device 1 or the second electronic device 2.

As shown in fig. 2, a charging contact 12 is provided in the decoration hole 11, and the length of the charging contact 12 is smaller than the depth of the decoration hole 11. Thus, the charging contact 12 does not protrude out of the opening plane of the decoration hole 11, and thus does not affect the appearance of the first electronic device 1. The charging contact 12 may charge the first electronic device 1 or the second electronic device 2, and for example, when the first electronic device 1 charges the second electronic device 2, the first electronic device 1 outputs electric energy to the second electronic device 2 as a power source. In the case that the charging contact 12 charges the first electronic device 1, the first electronic device 1 may be connected to an external power source through the charging contact 12 in the decoration hole 11 to charge the first electronic device 1, which is not limited in the embodiment of the present invention.

When the second electronic device 2 is charged through the decoration hole 11 included in the first electronic device 1, the second electronic device 2 may include a device body and a charging connector 22. The contact electrode 221 included in the charging connector 22 may be movably connected within the cavity of the device body. In the case where the second electronic device 2 is charged through the decoration hole 11 included in the first electronic device 1, the contact electrode 221 included in the charging connector 22 extends into the decoration hole 11, and the contact electrode 221 is brought into contact with the charging contact 12, thereby charging the second electronic device 2 through the first electronic device 1. After the charging is completed, the contact electrode 221 included in the charging connector 22 is disengaged from the decoration hole 11, and the contact electrode 221 and the charging contact 12 are separated, so that the first electronic device 1 charges the second electronic device 2. The contact electrode 221 may have a cylindrical shape, a rectangular parallelepiped shape, or another shape, and when the contact electrode 221 is inserted into the decorative hole 11 and is in contact with the charging contact 12, the wall of the decorative hole 11 does not contact the wall of the contact electrode 221.

As can be seen from the above embodiments, in the embodiment of the present invention, since the second electronic device 2 is charged through the decoration hole 11 included in the first electronic device 1, the second electronic device 2 includes the device body and the charging connector 22; the charging connector 22 is fixedly connected with the equipment body, the charging connector 22 comprises a contact electrode 221 and a connector body, and the contact electrode 221 is connected to the connector body; in the case where the second electronic device 2 is charged through the decoration hole 11, the contact electrode 221 is in contact with the charging contact 12, and therefore, in the case where the operator does not carry a dedicated charging device, the first electronic device 1 can charge the second electronic device 2 through the decoration hole 11, thereby being more convenient for the operator to use.

Alternatively, as shown in fig. 4 and 5, the second electronic device 2 includes a single-ended cavity, and the charging connector 22 includes a contact electrode 221 and a driving component 222; a first end of the driving component 222 is fixed in the cavity, and a second end of the driving component 222 is connected with the contact electrode 221; the contact electrode 221 is switched between a first state and a second state under the driving of the driving component 222; wherein in case of the first state the contact electrode 221 at least partially protrudes out of the mouth of the cavity and in case of the second state the contact electrode 221 retracts into the cavity.

Specifically, a cavity may be formed in the second electronic device 2, so that the second electronic device 2 forms a cavity. Charging connector 22 includes a drive assembly 222 having a first end fixed to an inner wall of the cavity, and drive assembly 222 may be one of a spring or a lead screw assembly capable of extending and retracting in two directions of movement. The contact electrode 221 may be electrically connected to the battery in the second electronic device 2 through a wire. When the driving assembly 222 extends toward the direction close to the mouth of the cavity, the contact electrode 221 is in the first state as shown in fig. 5, that is, the contact electrode 221 at least partially extends out of the mouth of the cavity, so that the contact between the contact electrode 221 and the charging contact 12 is facilitated. When the driving assembly 222 retracts away from the mouth of the cavity, the contact electrode 221 is caused to be in the second state as shown in fig. 4, that is, the contact electrode 221 retracts into the cavity, so that the contact electrode 221 and the charging contact 12 are disengaged. Thus, when the first electronic device 1 and the second electronic device 2 do not need to be charged, the contact electrode 221 can be retracted in the cavity, so that on one hand, the problem that the contact electrode 221 protrudes out of the second electronic device 2 to cause damage to the contact electrode 221 can be avoided, and on the other hand, the problem that the appearance of the second electronic device 2 as a whole is damaged as the contact electrode 221 protrudes out of the second electronic device 2 can be avoided.

Optionally, the driving assembly 222 is a first elastic member; in the second state, the first elastic member is in a contracted state.

Specifically, the second elastic member 2232 may be one of elastic members having a spring or elastic rubber, which has a resilient action. Therefore, when the contact electrode 221 is in a state of retracting in the cavity, the contact electrode 221 abuts against the first elastic member, so that the first elastic member is in a retracted state, and when the contact electrode 221 needs to extend out of the cavity, the contact electrode 221 extends out of the cavity under the action of the first elastic member, so that the contact between the contact electrode 221 and the charging contact 12 is facilitated.

Optionally, the first elastic member is a solenoid control spring.

Specifically, when the first elastic member is an electromagnetic control spring and the contact electrode 221 needs to extend out of the cavity, the second electronic device 2 energizes the first elastic member, so that the first elastic member extends to push the contact electrode 221 to extend out of the cavity. When the contact electrode 221 needs to retract into the cavity, the second electronic device 2 terminates the energization of the first elastic member, and the contact electrode 221 retracts into the cavity under the resilience force of the first elastic member. Therefore, the first elastic piece can be automatically stretched by controlling the electrifying state of the first elastic piece, so that the contact electrode 221 can be automatically stretched, and the charging process is more intelligent.

Optionally, as shown in fig. 4 and 5, the charging connector 22 further includes an electronic driving member 223 and a limiting rod 224; spacing hole 2241 has been seted up to contact electrode 221, the one end of gag lever post 224 with electronic drive piece 223 connects under the condition of second state, the other end joint of gag lever post 224 is in the spacing hole 2241 under the condition of first state, electronic drive piece 223 drive the other end of gag lever post 224 breaks away from spacing hole 2241.

It should be noted that the limiting rod 224 is a metal rod, and the limiting rod 224 may be fixed in the limiting hole 2241 or may be separated from the limiting hole 2241. When the contact electrode 221 is in the second state as shown in fig. 4, the other end of the stopper rod 224 is engaged with the stopper hole 2241. When the contact electrode 221 needs to extend out of the cavity, the electronic driving member 223 drives the other end of the limiting rod 224 to disengage from the limiting hole 2241, so that the contact electrode 221 is in the first state as shown in fig. 5. In this way, the automatic extension and retraction of the contact electrode 221 can be controlled by the electronic driver 223, making the charging process more intelligent.

Alternatively, as shown in fig. 4 and 5, the electronic driver 223 includes a solenoid 2231 and a second elastic member 2232; one end of the second elastic member 2232 is fixedly connected to the electromagnetic device 2231, and the other end of the second elastic member 2232 is fixedly connected to the limiting rod 224; when the electromagnetic device 2231 is in the energized state, the electromagnetic device 2231 and the limiting rod 224 are magnetically attracted to each other, the limiting rod 224 is separated from the limiting hole 2241, and the second elastic member 2232 is in the compressed state.

Specifically, the electromagnetic device 2231 may be one of electromagnets, and the second elastic element may be a spring or an elastic rubber. One end of the second elastic member 2231 is fixedly connected to the electromagnetic member 2232, and the other end of the second elastic member 2232 is fixedly connected to the stopper 224. The contact electrode 221 may have a stopper hole 2241 formed therein, and the stopper 224 is a metal rod. When the electromagnetic device 2231 is in the non-energized state, the electromagnetic device 2231 has no magnetism, and the limiting rod 224 is fixed in the limiting hole 2241. When the contact electrode 221 needs to extend out of the cavity, the second electronic device 2 energizes the electromagnetic device 2231, so that the electromagnetic device 2231 has magnetism, and the electromagnetic device 2231 attracts the limiting rod 224 to move toward a direction close to the electromagnetic device 2231, so that the second elastic element is compressed, the limiting rod 224 is urged to separate from the limiting hole 2241, and then the contact electrode 221 partially extends out of the mouth of the cavity under the action of the elastic force of the first elastic element, so that the contact electrode 221 is in the first state as shown in fig. 5. When the contact electrode 221 needs to retract back to the cavity, the second electronic device 2 energizes the electromagnetic device 2231, so that the magnetism of the electromagnetic device 2231 disappears, the limiting rod 224 pushes against the contact electrode 221 under the action of the resilience force of the second elastic element, one end of the contact electrode 221 close to the first elastic element is an arc surface, and the arc surface is gradually increased in radian close to the first elastic element, so that the limiting rod 224 is re-fixed in the limiting hole 2241 under the guidance of the arc surface of the contact electrode 221, and then the contact electrode 221 is driven to retract, and finally the contact electrode 221 retracts back to the cavity, that is, when the contact electrode 221 is in the second state as shown in fig. 4. In this way, the contact electrode 221 can be switched between the first state and the second state by controlling the power-on state of the electromagnetic device 2231, so that the charging process is more intelligent

Optionally, as shown in fig. 2, the first electronic device 1 further includes a first limiting assembly 15, and as shown in fig. 6, the second electronic device 2 includes a second limiting assembly 23; the first limiting component 15 is arranged around the opening of the decoration hole 11, and the second limiting component 23 is arranged around the position of the contact electrode 221; under the condition that the contact electrode 221 is communicated with the charging contact 12, the first limiting assembly 15 and the second limiting assembly 23 are connected in a matched mode.

Specifically, the first position-limiting assembly 15 may be disposed around the opening of the decorative hole 11, as shown in fig. 2, the first position-limiting assembly 15 may be disposed at least two of the four positions A, B, C, D in the drawing, the second position-limiting assembly 23 may be disposed at the position around the contact electrode 221, as shown in the drawing, the second position-limiting assembly 23 may be disposed at least two of the four positions E, F, G, H in the drawing, and the embodiment of the present invention is not limited thereto. In the case where the second electronic device 2 is charged through the decoration hole 11, the first stopper member 15 and the second stopper member 23 are fitted and connected so that the contact electrode 221 and the charging contact 12 are turned on. Note that, in the case where the contact electrode 221 and the charging contact 12 are communicated, the contact electrode 221 and the charging contact 12 are contacted in a preset order. The preset sequence is an arrangement sequence of the contact electrodes 221 of the charging contacts 22 from one side to the other side when the contact electrodes 221 and the charging contacts 12 are normally turned on. In this way, it is possible to avoid damaging the circuit of the first electronic device 1 or the second electronic device 2 when the contact electrode 221 and the charging contact 12 are reversely connected.

Alternatively, as shown in fig. 2 and 6, the first position-limiting assembly 15 at least comprises a set of oppositely disposed first and

second magnets

151 and 152, and the second position-limiting assembly 23 at least comprises a set of oppositely disposed third and

fourth magnets

231 and 232; in the case where the contact electrode 221 is in contact with the charging contact 12, the first magnet 151 and the third magnet 231 are magnetically attracted, and the third magnet 231 and the fourth magnet 232 are magnetically attracted, wherein the first magnet 151 and the second magnet 152 are opposite in magnetism.

Specifically, the first magnet 151, the second magnet 152, the third magnet 231 and the fourth magnet 232 may each be one of a bar magnet and a shoe magnet, the first magnet 151 may be disposed at A, B two positions in fig. 2, or disposed at C, D two positions in fig. 2, and the fourth magnet 232 may be disposed at E, F two positions in the figure, or disposed at G, H two positions in the figure, which is not limited by the embodiment of the present invention. The end of the first magnet 151 away from the decoration hole 11 is opposite to the end of the second magnet 152 away from the decoration hole 11, and the end of the fourth magnet 232 away from the driving assembly 222 is opposite to the end of the fifth magnet 153 away from the driving assembly 222. In the case where the contact electrode 221 is brought into contact with the charging contact 12, the contact electrode 221 and the charging contact 12 can be brought into contact in a preset order only in the case where the first and

fifth magnets

151 and 153 are magnetically attracted and the second and

sixth magnets

152 and 233 are magnetically attracted. Thus, it is possible to prevent a line fault caused by the reverse connection of the charging contact 12 of the contact electrode 221, and also to facilitate the operator to quickly connect the contact electrode 221 and the charging contact 12.

Further, the first position-limiting assembly 15 may further include at least one fifth magnet 153, and the second position-limiting assembly 23 includes at least one sixth magnet 233; the fifth magnet 153 and the first magnet 151 are located at different orientations of the charging contact 12, and the sixth magnet 233 and the third magnet 231 are located at different orientations of the contact electrode 221; alternatively, the first position limiting assembly 15 further comprises at least one set of oppositely disposed fifth and

seventh magnets

153, 154, and the second position limiting assembly 23 further comprises at least one set of oppositely disposed sixth and

eighth magnets

233, 234, wherein the fifth and

seventh magnets

153, 154 are opposite in magnetic polarity. In the case where the contact electrode 221 and the charging contact 12 are contacted in a preset order, the fifth magnet 153 and the sixth magnet 233 are magnetically attracted, and the seventh magnet 154 and the eighth magnet 234 are magnetically attracted.

It should be noted that, in a possible implementation manner, in a case that the first position-limiting assembly 15 may further include one fifth magnet 153, the second position-limiting assembly 23 further includes at least one sixth magnet 233, each of the fifth magnet 153 and the sixth magnet 233 may be one of a bar magnet or a horseshoe magnet, the fifth magnet 153 and the first magnet 151 are located in different orientations of the charging contact 12, and a length direction of the fifth magnet 153 may intersect a length direction of the first magnet 151. Specifically, the first magnet 151 and the second magnet 152 may be disposed at two positions A, B in fig. 2, and the fifth magnet 153 may be disposed at any one position C, D in fig. 2. The sixth magnet 233 and the third magnet 231 are located at different orientations of the contact electrode 221, and if the third magnet 231 is disposed in a direction that coincides with the expansion and contraction direction of the contact electrode 221, the sixth magnet 233 is disposed in a direction that intersects the expansion and contraction direction of the contact electrode 221, or the sixth magnet 233 is disposed in a direction that intersects the expansion and contraction direction of the contact electrode 221, and the third magnet 231 is disposed in a direction that coincides with the expansion and contraction direction of the contact electrode 221. Specifically, the third magnet 231 and the fourth magnet 232 may be disposed at two positions E, F in the drawing, and the sixth magnet 233 may be disposed at any one position G, H in the drawing. In this way, when the second electronic device 2 is charged through the decorative hole 11 included in the first electronic device 1, the contact electrode 221 and the charging contact 12 can be connected only when the three positions A, B, C and E, F, G or A, B, D and E, F, H are properly contacted.

In another possible implementation, in the case that the first position-limiting assembly 15 may further include at least one set of oppositely disposed fifth and

seventh magnets

153, 154, the second position-limiting assembly 23 may further include at least one set of oppositely disposed sixth and

eighth magnets

233, 234. The fifth magnet 153 and the seventh magnet 154 are oppositely disposed. Specifically, the first and

second magnets

151 and 152 may be disposed at two positions A, B in fig. 2, and the fifth and

sixth magnets

153 and 233 may be disposed at two positions C, D in fig. 2. The eighth magnet 234 and the sixth magnet 233 are oppositely disposed. Specifically, the third magnet 231 and the fourth magnet 232 may be disposed at two positions E, F in the drawing, and the sixth magnet 233 and the eighth magnet 234 may be disposed at two positions G, H in the drawing. Thus, when the second electronic device 2 is charged through the decoration hole 11 included in the first electronic device 1, the contact electrode 221 and the charging contact 12 can be contacted in the predetermined sequence only when the A, B, C, D four positions and the E, F, G, H four positions are correctly contacted, and since A, B, C, D is four different positions around the charging contact 12, the E, F, G, H four positions are four different positions around the contact electrode 221, the directions limited by A, B and C, D are different, and the directions limited by E, F and G, H are also different, the charging contact 22 and the decoration hole 11 are not connected in reverse in all directions.

It should be further noted that, in the case that the first position limiting assembly 15 includes multiple sets of the first magnet 151 and the second magnet 152 oppositely arranged or multiple sets of the fifth magnet 153 and the seventh magnet 154 oppositely arranged, the second position limiting assembly 23 may also include multiple sets of the third magnet 231 and the fourth magnet 232 oppositely arranged or multiple sets of the sixth magnet 233 and the eighth magnet 234 oppositely arranged, which is not described again in this embodiment of the present invention.

Optionally, the first limiting assembly 15 comprises at least one limiting groove, and the second limiting assembly 23 comprises at least one limiting block; the limiting groove is arranged around the opening of the decoration hole 11, and the limiting block is arranged around the contact electrode 221; under the condition that the contact electrode 221 is communicated with the charging contact 12, the limiting block is clamped in the limiting groove.

Specifically, in a possible implementation manner, in a case that the first limiting component 15 may include a first limiting groove, the second limiting component 23 may include a second limiting block, or in a case that the second limiting component 23 may include a second limiting block, the second limiting component 23 may include a second limiting groove. The first limiting groove and the second limiting block can be arranged at any position E, F, G, H in the figure. Thus, when the second electronic device 2 is charged through the decoration hole 11 included in the first electronic device 1, the contact electrode 221 and the charging contact 12 can be contacted in a preset sequence only under the condition that the first limiting block is clamped with the second limiting groove or the second limiting block is clamped with the first limiting groove.

In another possible implementation manner, in the case that the first limiting component 15 may include a first limiting groove and a first limiting block, the second limiting component 23 may include a second limiting groove and a second limiting block, and the second limiting groove and the second limiting block may be disposed at any two positions E, F, G, H in the figure. When the second electronic device 2 is charged through the decoration hole 11 included in the first electronic device 1, and the contact electrode 221 and the charging contact 12 can be contacted in a predetermined order, the first stopper needs to be clamped with the second stopper groove, and the second stopper needs to be clamped with the first stopper groove, so that the external charging contact 22 and the charging contact 12 can be prevented from being reversely connected.

It should be noted that, in the embodiment of the present invention, a plurality of second limiting grooves and second limiting blocks may also be provided, for example, two second limiting grooves may be provided at two positions E, G in the drawing, and two first limiting blocks may be provided at two positions F, H, so that the anti-reverse function is consistent with the above embodiment, and details of the embodiment of the present invention are not repeated.

Optionally, the first electronic device 1 further comprises a first processor; the first processor is electrically connected with a loop where the charging contact 12 is located, wherein the first processor is a device for controlling the loop where the charging contact 12 is located to be in a conducting state or a disconnecting state.

Specifically, in the case where the first processor is electrically connected to the circuit in which the charging contact 12 is located, the first processor may send an electrical signal to the charging contact 12 to control the circuit in which the charging contact 12 is located to be in the on state or the off state. When the external charging connector 22 is charged through the decoration hole 11, the circuit where the charging contact 12 is located is controlled to be in a conducting state. When the external charging connector 22 is charged, the circuit where the charging contact 12 is located is controlled to be in an open state, so as to end the external energy supply of the first electronic device 1.

Further, the charging contact 12 includes a power terminal 121 and a ground terminal 122; the first processor may control the loop in which the power supply terminal 121 is located to be in an on state or an off state. Specifically, the power supply terminal 121 is used for being connected to an output line of a battery of the first electronic device 1, and when the power supply terminal 121 receives a charging signal sent by the first processor, a loop in which the power supply terminal 121 is located is in a conducting state, that is, the power supply terminal 121 and the output line of the battery are conducted. When the power supply terminal 121 receives the charging signal sent by the first processor, the loop in which the power supply terminal 121 is controlled is in an open state, that is, the power supply terminal 121 and the output line of the battery are controlled to be disconnected.

Optionally, the second electronic device 2 further comprises a second processor; the second processor is a device that energizes the electromagnetic device 2231 after detecting that the battery power of the second electronic device 2 is lower than the first preset value, so that the electromagnetic device 2231 attracts the limiting rod 224 to disengage from the limiting hole 2241.

It should be noted that the battery capacity of the second electronic device 2 with the first preset value cannot provide the lowest capacity value when the second electronic device 2 is normally used. When the second processor detects that the battery power of the second electronic device 2 is lower than the first preset value, which means that the battery power of the second electronic device 2 cannot be supplied to the second electronic device 2 for normal use, the contact electrode 221 needs to be extended to charge the second electronic device 2 through the decoration hole 11. Therefore, the second processor energizes the electromagnetic device 2231, so that the electromagnetic device 2231 has magnetism, and the electromagnetic device 2231 attracts the limiting rod 224 to move in a direction close to the electromagnetic device 2231, so as to compress the second elastic element, and cause the second limiting rod 224 to separate from the limiting hole 2241, so that the contact electrode 221 extends out of the cavity under the action of the elastic force of the first elastic element, and is conveniently contacted with the charging contact 12 through the decoration hole 11.

Further, the second processor may be further configured to power off the electromagnetic device 2231 after powering on the electromagnetic device 2231 for a preset time; alternatively, after detecting that the battery power of the second electronic device 2 reaches the second preset value, the electromagnetic device 2231 is powered off. Specifically, the second preset value may be an electric quantity value at which the battery capacity of the second electronic device 2 reaches a rated storage capacity or a preset storage capacity. In this way, it is not necessary to wait until the second electronic device 2 is fully charged, or when the preset electric quantity is reached, the electromagnetic device 2231 may be controlled to be powered off, and thus, when the second electronic device 2 does not need to be charged or the charging is completed, the electromagnetic device 2231 may be controlled to be powered off, so that the contact electrode 221 is in a state of retracting in the cavity, and further the charging contact 12 and the contact electrode 221 are disconnected, and further the charging process is completed in the first time, so as to shorten the response time of the system, and the battery of the first electronic device 1 may be interrupted to output the external electric quantity in the first time when the charging is completed, which is beneficial to reducing the energy waste of the first electronic device 1, and increasing the endurance time of the first electronic device 1.

Alternatively, as shown in fig. 2 and the drawings, in the case where the charging contact 12 of the first electronic device 1 includes the detection terminal 123, the power supply terminal 121, and the ground terminal 122, the contact electrode 221 includes a detection electrode 2213, a power supply electrode 2211, a ground electrode 2212; the detection electrode 2213 is adapted to be in contact with the detection terminal 123, the power supply electrode 2211 is adapted to be in contact with the power supply terminal 121, and the ground electrode 2212 is adapted to be in contact with the ground electrode 2212. Specifically, in the case where the second electronic device 2 is charged through the decorative hole 11 included in the first electronic device 1, the detection electrode 2213 is in contact with the detection terminal 123, the power supply electrode 2211 is in contact with the power supply terminal 121, and the ground electrode 2212 is in contact with the ground electrode 2212, so that the charging contact 12 is in direct contact with the contact electrode 221, and further, the first electronic device 1 can normally charge the second electronic device 2. Secondly, since the detection electrode 2213 is in contact with the detection terminal 123, the whole charging process can be completed under the control of the first processor and the second processor, so that the whole charging process is controllable.

Optionally, the charging contact 12 further comprises a detection terminal 123; the detection terminal 123 is electrically connected to the first processor, and when the contact electrode 221 and the charging contact 12 are in contact or disconnected, the level of the detection terminal 123 changes.

It should be noted that the level signal of the power detection terminal 123 may transmit a level change of "1-0" or "0-1". Specifically, when the external charging connector 22 and the charging contact 12 are not in contact, the level of the power supply detection terminal 123 may be "1", and when the external charging connector 22 and the charging contact 12 are in contact, the level of the power supply detection terminal 123 is changed from "1" to "0", in which case, when the first processor detects that the level of the power supply detection terminal 123 is changed from "1" to "0", the loop in which the power supply terminal 121 is located may be controlled to be in the on state. When the first processor detects that the level of the power detection terminal 123 is changed from "0" to "1", which indicates that the external charging connector 22 and the charging contact 12 are changed from a contact state to a non-contact state, the first processor controls the circuit in which the power terminal 121 is located to be in an open state. Alternatively, the level of the power detection terminal 123 may be "0" when the external charging connector 22 and the charging contact 12 are not in contact, and the level of the power detection terminal 123 is changed from "0" to "1" when the external charging connector 22 and the charging contact 12 are in contact, in which case, when the first processor detects that the level of the power detection terminal 123 is changed from "0" to "1", the loop in which the power terminal 121 is located may be controlled to be in a conductive state. When the first processor detects that the level of the power detection terminal 123 is changed from "1" to "0", which indicates that the external charging connector 22 and the charging contact 12 are changed from a contact state to a non-contact state, the first processor controls the circuit in which the power terminal 121 is located to be in an open state. In this way, by detecting the level change of the detection terminal 123, the loop where the power terminal 121 is located can be controlled to be in the on state or the off state at the first time, the external charging connector 22 and the charging contact 12 are turned on at the first time or the charging process is finished at the first time, the response time of the system is shortened, and the output of the battery of the first electronic device 1 to the external electric quantity can be interrupted at the first time when the charging is finished, which is beneficial to reducing the energy waste of the first electronic device 1 and increasing the endurance time of the first electronic device 1.

In addition, the charging connector 22 further includes an electronic driving member 223 and a stopper 224; the contact electrode 221 has a limiting hole 2241, one end of the limiting rod 224 is connected to the electronic driving member 223, the other end of the limiting rod 224 is engaged with the limiting hole 2241 in the second state, and the electronic driving member 223 drives the other end of the limiting rod 224 to be separated from the limiting hole 2241 in the first state. In this way, the automatic extension and retraction of the contact electrodes 221 can be controlled by the electronic drive 223, making the charging process more intelligent. In addition, by detecting the level change of the detection terminal 123, the loop where the power terminal 121 is located can be controlled to be in the on state or the off state at the first time, the external charging connector 22 and the charging contact 12 are turned on at the first time or the charging process is finished at the first time, the response time of the system is shortened, and the output of the battery of the first electronic device 1 to the outside electric quantity can be interrupted at the first time when the charging is finished, which is beneficial to reducing the energy waste of the first electronic device 1 and increasing the endurance time of the first electronic device 1.
