[Charging equipment hardware architecture]

Please refer to Figures 1, 2 and 3, wherein Figure 1 is a schematic diagram of the structure of the charging device provided in the embodiment of the present invention. Figure 2 is a schematic diagram of the appearance of the charging device provided in the embodiment of the present invention when it is not charged. Figure 3 is a schematic diagram of the appearance of the charging device provided in the embodiment of the present invention when it is charging.

The charging device P provided in the embodiment of the present invention refers to a second charging device P2 and a first charging device P1 that can be separated or contacted with each other. The second charging device P2 mentioned here can provide a charging power source to the first charging device P1. When the first charging device P1 obtains the charging power source, it can charge a power source to be charged (such as a rechargeable battery).

For example, the charging device P is used by installing the first charging device P1 on the door panel and the second charging device P2 on the door frame, and the positions of the second charging device P2 and the first charging device P1 are respectively arranged in such a way as not to affect the normal opening and closing of the door panel, and when the door panel is closed, the first charging device P1 on the door panel corresponds to the second charging device P2 on the door frame. The charging device P charges the electronic access control system installed on the door panel, and the access control device used in the electronic access control system is, for example, but not limited to, an electronic lock or an electronic monitor.

Furthermore, the charging behavior between the second charging device P2 and the first charging device P1 is wired charging through mutual contact. As shown in Figure 2, when the second charging device P2 and the first charging device P1 are separated and not in contact, the second charging device P2 will not provide charging power to the first charging device P1, that is, the first charging device P1 will not charge the power to be charged.

As shown in FIG3, when the second charging device P2 and the first charging device P1 are in contact with each other, the contact mentioned here means that the retractable first charging contact part 15 in the first charging device P1 is exposed to the first charging device P1, and when the positions of the second charging device P2 and the first charging device P1 correspond, the first charging contact part 15 at this time is inserted into the second charging contact part 22 in the second charging device P2 for electrical contact. That is, at this time, the second charging device P2 can provide charging power to the first charging device P1 through the second charging contact part 22, and the first charging device P1 can charge the power to be charged after obtaining the charging power.

It should be particularly noted that the first charging device P1 controls whether the first charging contact portion 15 is retracted into the first charging device P1 as shown in FIG. 2 or extended out of the first charging device P1 as shown in FIG. 3 according to the judgment result of the charging condition. For example, when the first charging device P1 determines that the current power supply to be charged does not meet the power supply specified by the charging condition, the first charging contact portion 15 of the first charging device P1 is retracted into the first charging device P1 as shown in FIG2, and when the first charging device P1 determines that the current power supply to be charged meets the power supply specified by the charging condition, the first charging contact portion 15 of the first charging device P1 is extended out of the first charging device P1 as shown in FIG3, and is electrically contacted with the second charging contact portion 22 of the second charging device P2 to obtain the charging power supply to charge the power supply to be charged.

In one embodiment, the charging condition may be one or more, and the relevant judgment contents of the charging condition will be described later.

In one embodiment, the second charging device P2 can also determine whether the first charging device P1 has contacted the second charging contact portion 22 by sensing, and can control whether the charging power is outputted according to the determination result. For example, when the second charging device P2 determines that the first charging device P1 has not contacted the second charging contact portion 22, the second charging device P2 stops the charging power from being outputted from the second power transmission interface 23 of the second charging contact portion 22. When the second charging device P2 determines that the first charging device P1 has contacted the second charging contact portion 22, the second charging device P2 can control the charging power to be output from the second power transmission interface 23 of the second charging contact portion 22, and in order to prevent the generation of contact sparks, the second charging device P2 can control the charging power to be output after a period of time.

In one embodiment, the first charging device P1 can also sense whether a person is approaching, and control whether the first charging contact 15 is retracted into the first charging device P1 according to the sensing result. For example, when the first charging device P1 and the second charging device P2 are performing wired charging in the manner shown in FIG3, if it senses that someone is approaching the first charging device P1, the first charging contact 15 of the first charging device P1 will automatically retract into the first charging device P1 as shown in FIG2.

In one embodiment, the first charging contact 15 and the second charging contact 22 form a conical surface on one side thereof, and the second charging device P2 forms arc portions 221 on both sides of the second charging contact 22. When the first charging contact 15 obtains the charging power provided by the second charging device P2 in the manner shown in FIG3, if an external force is applied to the exposed first charging contact 15 (e.g., the door opening action), the first charging contact 15 can be retracted into the first charging device P1 through the internal elastic structure design and the squeezing of the arc portion 221, and when the external force disappears, the first charging contact 15 can be restored to the position extending outside the first charging device P1.

In one embodiment, the first charging device P1 can control the first charging contact 15 to move between the first position and the second position. The first position (or charging position) described herein is, for example, as shown in FIG. 3, where the first charging contact 15 moves to the outside of the first charging device P1 and contacts the second charging contact 22 of the second charging device P2. The second position (or standby position) described herein is, for example, as shown in FIG. 2, where the first charging contact 15 moves to the inside of the first charging device P1 and does not contact the second charging contact 22 of the second charging device P2.

It should be noted that the aforementioned first charging contact portion 15 can perform a translational movement of extending or retracting relative to the first charging device P1, but the first charging contact portion 15 can also perform the aforementioned wired charging contact movement with the second charging contact portion 22 through other different movement methods. For example, the first charging contact portion 15 can perform a rotational movement or a warping movement relative to the first charging device P1 to perform a wired charging contact movement with the second charging contact portion 22, but the present invention is not limited to this.

In one embodiment, the contact actions performed by the first charging contact portion 15 and the second charging contact portion 22 can also be interchanged. For example, the first charging contact portion 15 is fixed, and the movable second charging contact portion 22 performs the aforementioned charging action (such as translation, rotation or flapping) to contact the first charging contact portion 15.

Next, an example is given to illustrate the internal structure of the charging device, and please refer to Figure 4, Figure 5A to Figure 5C, where Figure 4 is a cross-sectional view of the charging device when it is not charged according to an embodiment of the present invention. Figure 5A is a cross-sectional view of the charging device when it is charged according to an embodiment of the present invention. Figure 5B is a schematic diagram of the first charging contact being squeezed by an external force when the charging device is charged according to an embodiment of the present invention. Figure 5C is a schematic diagram of the internal structure of the charging device when it is charged according to an embodiment of the present invention.

First, please refer to Figure 4. The first charging device P1 includes a receiving housing C1, and a first control board 11, a driving unit 13, a first charging contact 15 and a charging battery B are arranged in the receiving housing C1. The first control board 11 is used to control the charging of the first charging device P1, and the driving unit 13 is controlled by the first control board 11 and is used to control the movement of the first charging contact 15. As mentioned above, the first charging contact 15 is used to contact the second charging device P2 to obtain charging power, and the first control board 11 uses this charging power to charge the charging battery B (i.e., the aforementioned power to be charged).

Furthermore, the first control board 11 detects whether the power of the charging battery B is too low and needs to be charged, so the first control board 11 outputs a charging instruction or a charging stop instruction to the driving unit 13 according to the result of detecting the power of the charging battery B.

When the driving unit 13 receives a charging instruction, it controls the first charging contact 15 to move to the first position, and when the driving unit 13 receives a stop charging instruction, it controls the first charging contact 15 to move to the second position.

In one embodiment, when the first control panel 11 senses that a person is approaching the first charging device P1 and the first charging contact portion 15 is at the first position, the first control panel 11 can output a stop charging instruction to the driving portion 13 to move the first charging contact portion 15 to the second position.

In one embodiment, the driving part 13 includes, but is not limited to, a motor part 131 and a gear part 133, and the gear part 133 is driven to rotate by the rotation of the axis of the motor part 131. The axis rotation direction and rotation time of the motor part 131 are controlled by the first control board 11.

In one embodiment, the first charging contact portion 15 includes, for example but not limited to, a tooth portion 151 , a connecting rod 153 , an elastic element (such as a spring) 17 and a charging contact head 155 . The connecting rod 153 is pivotally connected to the toothed portion 151 and the charging contact 155, the elastic element 17 is inserted into the connecting rod 153, and the fixed end 171 of the elastic element 17 is fixedly connected to the connecting rod 153, and the movable end 173 of the elastic element 17 abuts against one side of the charging contact 155, so that when the charging contact 155 is squeezed by an external force, the charging contact 155 moves toward the fixed end 171 of the elastic element 17 along the direction of the connecting rod 153, and the side of the charging contact 155 that contacts the second charging contact portion 22 forms a cone.

It should be noted that the charging contact 155 has a through hole 1553 for one end of the connecting rod 153 to penetrate, and a positioning ring 1531 is convexly provided at one end of the connecting rod 153, and a stopper 1551 is concavely provided inside the through hole 1553. Therefore, when the connecting rod 153 is penetrated in the through hole 1553, one end of the connecting rod 153 is formed with the positioning ring 1531 and abuts against the stopper 1551 of the through hole 1553 through the positioning ring 1531. At this time, the movable end 173 of the elastic element 17 is subjected to elastic force (restoring elastic force), which will cause the stopper 1551 inside the charging contact 155 to move toward the positioning ring 1531, so that the positioning ring 1531 of the connecting rod 153 and the stopper 1551 of the charging contact 155 can be more closely pressed together.

Furthermore, as shown in FIG. 5C , the gear portion 151 is a roughly rectangular hollow frame, and a gear row is formed on the inner side of the hollow frame, and the gear row and the gear portion 133 are mutually engaged. Therefore, when the gear portion 133 rotates, the gear portion 151 can be driven to move in a linear direction. Here, the linear direction movement refers to the linear direction in which the gear portion 151 moves from the inside to the outside of the first charging device P1, or the linear direction movement can also refer to the linear direction in which the gear portion 151 moves from the outside to the inside of the first charging device P1.

It should be noted that the specific movement of the first charging contact portion 15 can be divided into two types: charging movement (moving from the inside of the first charging device P1 to the outside) and non-charging movement (moving from the outside of the first charging device P1 to the inside).

When the first charging device P1 is in a non-charging standby mode, the first control board 11 can drive the gear part 133 to rotate (for example, reversely) through the motor part 131 as shown in FIG. 4 . At this time, the gear part 151 moves from the outside of the first charging device P1 to the inside, and the connecting rod 153 and the charging contact head 155 can move synchronously with the gear part 151 until the charging contact head 155 is completely moved to the inside of the first charging device P1. At this time, the first control board 11 can control the motor part 131 to stop running, and finally the position of the first charging contact part 15 is the aforementioned first position (or standby position). Therefore, the first charging device P1 is completely separated from the second charging device P2 and has no contact with it, that is, the first charging device P1 cannot obtain the charging power provided by the second charging device P2 for charging.

When the first charging device P1 is in the charging mode, the first control board 11 can drive the gear part 133 to rotate (for example, forward rotation) through the motor part 131 as shown in FIG. 5A . At this time, the gear part 151 moves from the inside of the first charging device P1 to the outside, and the connecting rod 153 and the charging contact head 155 can move synchronously with the gear part 151 until the charging contact head 155 completely contacts the second charging contact part 22 of the second charging device P2. At this time, the first control board 11 can control the motor part 131 to stop running, and finally the position of the first charging contact part 15 is the aforementioned second position (or charging position). Therefore, after the charging contact head 155 of the first charging device P1 contacts the second charging contact part 22 of the second charging device P2, the first charging device P1 can successfully obtain the charging power provided by the second charging device P2 for charging.

It should be noted that the positioning ring 1531 of the connecting rod and the stopper 1551 of the charging contact head 155 in FIG. 4 and FIG. 5A can be more closely pressed together without the influence of external force. However, when the first charging device P1 contacts the second charging device P2 in the manner of FIG. 5A, if the side of the charging contact head 155 in contact with the second charging contact part 22 is squeezed by external force, and when the external force is greater than the restoring elastic force of the elastic element 17, the charging contact head 155 will be retracted to the first charging device P1 as shown in FIG. 5B, but the connecting rod 153 is maintained at the same position as FIG. 5A.

Furthermore, the main difference between FIG. 5B and FIG. 5A is that the charging contact 155 is retracted into the first charging device P1 due to the external force, and the charging contact 155 retracts because the elastic element 17 is subjected to the compressive elastic force due to the external force, and drives the charging contact 155 to move toward the fixed end 171 of the elastic element 17, and until the external force disappears, the charging contact 155 will move toward the outside of the first charging device P1 due to the recovery elastic force of the elastic element 17, and finally the charging contact 155 returns to the position described in FIG. 5A.

In one embodiment, the first power transmission interface 1731 and the first sensing interface 1733 are provided on the side where the charging contact head 155 contacts the second charging contact portion 22, and the second power transmission interface 23 and the second sensing interface 25 are also provided on the side where the second charging contact portion 22 contacts the charging contact head 155. Therefore, when the charging contact head 155 contacts the second charging contact portion 22, the second power transmission interface 23 and the first power transmission interface 1731 can be electrically connected to each other, and the second sensing interface 25 and the first sensing interface 1733 can also correspond to each other.

Furthermore, when the charging contact 155 and the second charging contact portion 22 are in contact with each other, the second charging device P2 can output the charging power through the second power transmission interface 23, and the first charging device P1 can receive the charging power through the first power transmission interface 1731. The second power transmission interface 23 or the first power transmission interface 1731 can be, for example, a metal terminal interface (for example, transmitting the charging power through two metal contacts).

It should be particularly noted that when the charging contact head 155 and the second charging contact portion 22 are in contact with each other, at least one of the second charging device P2 and the first charging device P1 can delay the output of charging power or delay the reception of charging power to avoid the generation of contact sparks. Further, the second sensing interface 25 can be a magnetic sensing element (such as a Hall sensor), and the first sensing interface 1733 can be a magnetic element (such as a magnet). In other embodiments, the second sensing interface 25 and the first sensing interface 1733 can also be a light transmitter and a light receiver, but the present invention is not limited to this.

In one embodiment, when the second charging device P2 senses the magnetic field change of the magnetic element through the magnetic induction element, the second charging device P2 can know that the charging contact head 155 has contacted the second charging contact part 22. At this time, the second charging device P2 outputs the charging power through the second power transmission interface 23 after a period of delay.

In one embodiment, when the first charging device P1 outputs a charging command, the first control board 11 obtains the charging power from the first power transmission interface 1731 after a delay.

Please refer to FIG. 6 again, which is a functional block diagram of a charging device provided in an embodiment of the present invention. In one embodiment, the first charging device P1 of the charging device P, for example, includes a control circuit 111, a sensing circuit 113, a driving unit 13, a first charging contact 15, and a charging battery B. The control circuit 111 and the sensing circuit 113 can be, for example, disposed on the first control board 11 in FIG. 4, and the control circuit 111 is electrically connected to the driving unit 13, the sensing circuit 113, and the charging battery B. The first charging contact 15 has a first power transmission interface 1731 and a first sensing interface 1733, and the first power transmission interface 1731 and the first sensing interface 1733 can be disposed on the charging contact head 155 as shown in FIG. 4.

For the control circuit 111, the first charging contact part 15 can be controlled to move to the first position or the second position via the driving part 13. When the first charging contact part 15 is at the first position, the first charging contact part 15 is exposed to the first charging device P1, and when the second charging device P2 corresponds to the first charging device P1, the first charging contact part 15 extends into the second charging contact part 22 of the second charging device P2. At this time, the control circuit 111 can obtain the charging power provided by the second charging device P2 through the first power transmission interface 1731 of the first charging contact part 15, and use the charging power to charge the rechargeable battery B.

When the first charging contact portion 15 is at the second position, the first charging contact portion 15 is retracted into the first charging device P1 and away from the second charging contact portion 22 of the second charging device P2. At this time, the control circuit 111 can no longer obtain the charging power through the first power transmission interface 1731, and the control circuit 111 stops charging the rechargeable battery B.

Furthermore, the control circuit 111 outputs a charging instruction or a charging stop instruction to the driving unit 13 according to a judgment of a charging condition, so that the driving unit 13 controls the first charging contact 15 to move to the first position when receiving the charging instruction, or controls the first charging contact 15 to move to the second position when receiving the charging stop instruction.

In one embodiment, the control circuit 111 can further sense that a person is approaching the first charging device P1 when the sensing circuit 113 senses that the first charging contact portion 15 is already at the first position. At this time, the control circuit 111 can output a stop charging instruction to the driving portion 13, so that the first charging contact portion 15 moves to the second position.

In one embodiment, the first charging device P1 may include a delay switch circuit. When the control circuit 111 outputs a charging command, the control circuit 111 may control the delay switch circuit to delay for a period of time before conducting the power supply path between the first power transmission interface 1731 and the charging battery B, so that the first charging device P1 can delay for a period of time before receiving the charging power provided by the second charging device P2.

In one embodiment, the charging condition may be, for example, the first charging condition or the second charging condition, and the control circuit 111 may output a charging instruction when the charging condition meets one of the first charging condition and the second charging condition. Here, the first charging condition is, for example, that the power of the charging battery B is less than the minimum safe power and is during off-peak hours. And here, the second charging condition is that the power of the charging battery B is less than the low power and is during off-peak hours.

In one embodiment, when the first charging device P1 is executed in a charging mode, and when the power of the charging battery B is charged to full power, the control circuit 111 outputs a stop charging instruction to stop the charging power supply from charging the charging battery B. The safe minimum power here is less than the low power, and the full power is greater than the low power. And the charging battery B can be set inside the first charging device P1 or the aforementioned electronic access control system.

In one embodiment, the second charging device P2 of the charging device P includes, for example, a second control board 21, a second charging contact portion 22, and an indicator light 27, wherein the second control board 21 can be disposed in the power supply housing C2 shown in FIG. 5C , and the second control board 21 is electrically connected to the second power transmission interface 23, the second sensing interface 25, and the indicator light 27. The second control board 21 can obtain an external power source (such as a mains power source or a DC power source), and when the second control board 21 obtains the mains power source, it can be converted into a charging power source through an AC-DC converter, or when the second control board 21 obtains the DC power source, it can be converted into a charging power source through a DC converter, that is, the second control board 21 can convert the external power source into a charging power source that can be used by the first charging device P1. In other embodiments, the second control board 21 can be combined with a DC power connection and a reverse connection protection circuit to convert the external power into a charging power.

Here, the second control board 21 outputs the charging power through the second power transmission interface 23, and determines whether the first charging contact 15 of the first charging device P1 has contacted the second charging contact 22 through the second sensing interface 25. For example, when the second control board 21 senses the first sensing interface 1733 of the first charging device P1 through the second sensing interface 25, it can be determined that the first charging contact 15 is in contact with the second charging contact 22. At this time, the second control board 21 can delay for a period of time and then output the charging power to the first charging device P1 through the second power transmission interface 23.

In addition, the second control panel 21 can also indicate the power supply status of the second charging device P2 through the indicator light 27. For example, when the second control panel 21 does not output the charging power through the second power transmission interface 23, the second control panel 21 controls the indicator light 27 to display the first light signal, and when the second control panel 21 has output the charging power through the second power transmission interface 23, the second control panel 21 controls the indicator light 27 to display the second light signal. Here, the first light signal and the second light signal display different light signals, for example, different color light signals or different flashing frequencies.

In one embodiment, the second charging device P2 may not include the second sensing interface 25 and the first charging device P1 may not include the first sensing interface 1733, so that the second charging device P2 can continue to output charging power through the second power transmission interface 23, and the first charging contact portion 15 of the first charging device P1 can directly obtain the charging power provided by the second charging device P2 when it moves to the first position.

In one embodiment, the control circuit 111 may be one or any combination of an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or a system on a chip (SOC), but the present invention is not limited thereto.

[Example of charging method]

Please refer to Figure 7, which is a control flow chart of the second charging device provided in an embodiment of the present invention. The flow chart shown in Figure 7 is an example of the structure of the aforementioned embodiment, but is not limited thereto. The process shown in Figure 7 is executed on the second charging device P2 of the charging device P, and includes the following steps.

In step S701, position detection is performed. Here, the second charging device P2 detects whether the first charging contact 15 of the first charging device P1 contacts the second charging contact 22 of the second charging device P2 through the second sensing interface 25.

In step S703, position determination is performed. Here, the position of the first charging contact portion 15 can be determined based on the sensing result of the second sensing interface 25 to determine whether it is in contact with the second charging contact portion 22. When step S703 determines that it is connected (i.e., the second charging contact portion 22 is in contact with the first charging contact portion 15), step S705 is executed; when step S703 determines that it is not connected (i.e., the second charging contact portion 22 is not in contact with the first charging contact portion 15), step S701 is executed.

In step S705, a delay is performed. Here, the second charging device P2 outputs the charging power from the second power transmission interface 23 after a delay. For example, the second charging device P2 may be provided with a microcontroller on the second control board 21, and when the second sensing interface 25 senses the first sensing interface 1733, the microcontroller controls the charging power to be output from the second power transmission interface 23 after a period of time. Alternatively, the second charging device P2 may also be provided with a delayed output circuit on the second control board 21, and when the second sensing interface 25 senses the first sensing interface 1733, the delayed output circuit controls the charging power to be delayed for a period of time before being output to the second power transmission interface 23. Here, the delayed output circuit is, for example, a capacitor, which is first charged by a charging power source, and after the capacitor is fully charged, the charging power source is output from the second power transmission interface 23. Here, the delayed output circuit is a capacitor for illustration only and is not intended to limit the present invention.

In step S707, power is supplied. That is, the second charging device P2 can output charging power to the first charging device P1 through the second power transmission interface 23.

Please refer to Figure 8, which is a control flow chart of the first charging device provided in an embodiment of the present invention. The flow chart shown in Figure 8 is an example of the structure of the aforementioned embodiment, but is not limited thereto. The process shown in Figure 8 is executed on the first charging device P1 of the charging device P, and includes the following steps.

In step S801, power detection is performed. Here, the first charging device P1 detects the power of the charging battery B.

In step S803, the power is determined. Here, according to the power detection result of step S801, the first charging device P1 can determine whether the charging battery B meets the charging conditions according to the power determination result. For example, the determination result of step S803 can be divided into conditions a, b, and c. Here, condition a means that the power of the charging battery B is less than the minimum safe power and is during off-peak hours, condition b means that the power of the charging battery B is less than the low power and is during off-peak hours, and condition c means that the power of the charging battery B is greater than the full power. When the determination result of step S803 meets condition a or b, step S805 is executed. When the result of step S803 meets condition c, step S801 is executed.

In step S805, the moving state is determined. Here, the first charging device P1 determines whether the first charging contact 15 is extended outside the first charging device P1 or retracted inside the first charging device P1 according to the moving position of the first charging contact 15. For example, when the first charging contact 15 moves to the first position, it is determined to be in the extended state, and when the first charging contact 15 moves to the second position, it is determined to be in the retracted state. When step S805 determines that the moving state is an extended state, step S807 is executed; when step S805 determines that the moving state is a retracted state, step S815 is executed.

In step S807, charging is judged. When the first charging device P1 obtains a charging power source to charge the charging battery B, the judgment result in this step S807 can be divided into conditions d and e. Condition d means that the power of the charging battery B is greater than the full power or someone is close to the first charging device P1, and condition e means that the power of the charging battery B is less than the low power and no one is close to the first charging device P1. When the judgment result of step S807 meets condition d, step S813 is executed. When the judgment result of step S807 meets condition e, step S809 is executed.

In step S809, maintain the first position. The first charging device P1 controls the first charging contact 15 to maintain the first position to continuously obtain charging power.

In step S811, charging. The first control board 11 obtains the charging power through the first power transmission interface 1731 of the first charging contact part 15 to charge the rechargeable battery B.

In step S813, it moves to the second position. Here, the first control board 11 controls the first charging contact part 15 to move to the second position through the driving part 13.

In step S815, someone approaches. The first control board 11 can know whether someone approaches the first charging device P1 through the sensing circuit 113. When step S815 determines that it is yes, step S801 is executed; and when step S815 determines that it is no, step S817 is executed.

In step S817, it moves to the first position. Here, the first control board 11 controls the first charging contact part 15 to move to the first position through the driving part 13, so as to charge the rechargeable battery B by obtaining the charging power source.

Please refer to Figures 9 and 10, wherein Figure 9 is a schematic diagram of the charging device provided by the embodiment of the present invention when it is installed on the door panel and not charged. Figure 10 is a schematic diagram of the charging device provided by the embodiment of the present invention when it is installed on the door panel and charged. When the charging device P is applied to the electronic access control system, that is, the electronic access control system includes the charging device P and the access control device, and the charging battery used by the access control device is charged by the charging device P, wherein the first charging device P1 is set on the door panel and the second charging device P2 is set on the door frame. The access control device is taken as an example of the electronic lock L1. Through this setting, the charging device P can charge the charging battery used by the electronic lock L1.

As shown in Figure 9, when the first charging device P1 determines that the charging conditions are not met or senses that there is a person near the door panel, the first charging contact portion 15 of the first charging device P1 is retracted into the first charging device P1, that is, the second charging device P2 will not provide charging power to the first charging device P1.

For example, in FIG10, when the first charging device P1 determines that the charging conditions are met and no one is detected near the door panel, the first charging contact portion 15 of the first charging device P1 is extended out of the first charging device P1, that is, the second charging device P2 can provide charging power to the first charging device P1, and the first charging device P1 can charge the charging battery according to the obtained charging power. However, during the charging process, if the first charging device P1 senses that someone is approaching the door panel or receives an unlocking signal from the electronic lock L1, the first charging device P1 will return to the state of FIG9.

Please refer to FIG. 11 again, which is another functional block diagram of a charging device provided in an embodiment of the present invention. The difference between the structure shown in FIG. 11 and the structure shown in FIG. 6 is that the contact action of wired charging between the first charging device P1 and the second charging device P2 is different. In FIG. 6, the first charging contact portion 15 of the first charging device P1 is movable, while the second charging contact portion 22 of the second charging device P2 is fixed and cannot be moved. In the case of the charging device P in FIG. 11, the first charging contact portion 15 of the first charging device P1 is fixed and cannot be moved, while the second charging contact portion 22 of the second charging device P2 is movable. The following only describes the difference.

As shown in FIG11 , the first charging device P1 of the charging device P, for example, includes a first control board 11, a first charging contact 15a, a first wireless circuit 19, and a charging battery B. The first control board 11 is electrically connected to the first charging contact 15a, the first wireless circuit 19, and the charging battery B. The second charging device P2 of the charging device P, for example, includes a second control board 21, a drive unit 13a, a second charging contact 22a, an indicator light 27, and a second wireless circuit 29. The first control board 11 is electrically connected to the first charging contact 15a, the indicator light 27, and the second wireless circuit 29.

It should be particularly noted here that the second control board 21 can control the second charging contact portion 22a to move to the first position through the driving portion 13a, that is, at this time the second charging contact portion 22a can contact the first charging contact portion 15a, so that the second power transmission interface 23 can be electrically connected to the first power transmission interface 1731, and the second sensing interface 25 can correspond to the first sensing interface 1733 to sense each other. The second control board 21 can also control the second charging contact 22a to move to the second position through the driving part 13a, that is, at this time, the second charging contact 22a can no longer contact the first charging contact 15a, so that the second power transmission interface 23 can no longer be electrically connected to the first power transmission interface 1731, and the second sensing interface 25 can no longer correspond to the first sensing interface 1733 for mutual sensing.

Furthermore, the first position described in FIG. 11 means that the second charging contact portion 22a can be moved outside the second charging device P2, and the second position means that the second charging contact portion 22a is moved inside the second charging device P2. In addition to the telescopic movement described in the above embodiments, the driving portions 13 and 13a in FIG. 6 and FIG. 11 can also be moved by other movement methods such as translation, rotation or blade movement, but the present invention is not limited thereto.

In one embodiment, the first wireless circuit 19 of the first charging device P1 and the second wireless circuit 29 of the second charging device P2 can communicate with each other wirelessly to transmit relevant information. For example, the first control board 11 in the first charging device P1 can detect the power status of the charging battery B, and transmit the detection result to the second wireless circuit 29 through the first wireless circuit 19 in a regular or irregular manner. Here, the first wireless circuit 19 or the second wireless circuit 29 can be, for example, a Bluetooth circuit or an RF circuit, but the present invention is not limited to this.

When the second control board 21 of the second charging device P2 obtains the power information of the charging battery B through the second wireless circuit 29, the second control board 21 can perform the judgment of the charging condition according to the power information, and further control the movement position of the second charging contact part 22a according to the judgment result. For example, when the second control board 21 judges that the charging condition is met, the second control board 21 can control the second charging contact part 22a to move to the first position through the driving part 13a, and when the second control board 21 judges that the charging condition is not met, the second control board 21 can control the second charging contact part 22a to move to the second position through the driving part.

When the second charging contact 22a moves to the first position and contacts the first charging contact 15a, the second control board 21 can convert the external power into charging power after appropriate power conversion, and the charging power can be transmitted to the first power transmission interface 1731 through the second power transmission interface 23. When the first control board 11 obtains the charging power through the first power transmission interface 1731, it can use the charging power to charge the rechargeable battery B.

In one embodiment, the second control board 21 may also include the sensing circuit 113 shown in FIG6, and the sensing result of the sensing circuit 113 may be used to know whether a person is close to the second charging device P2. For example, when the second charging contact portion 22a moves to the first position, and the sensing circuit 113 senses that a person is close to the second charging device P2, the second control board 21 may control the second charging contact portion 22a to move to the second position through the driving portion 13a.

In one embodiment, the first charging device P1 in FIG. 11 may also execute the control process of FIG. 7, and the second charging device P2 in FIG. 11 may also execute the control process of FIG. 8.

Next, examples are given to illustrate various possible mobile contact methods in the first charging device P1 and the second charging device P2.

The first control board 11 in the first charging device P1 can control the blade of the first charging contact portion 15b to move to the first position in FIG13a via the driving unit 13, or the first control board 11 in the first charging device P1 can also control the blade of the first charging contact portion 15b to move to the second position in FIG13b via the driving unit 13, that is, at this time, the first charging contact portion 15b is in contact with the second charging contact portion 22b.

Please refer to Figure 14a and Figure 14b, wherein Figure 14a is a schematic diagram of the charging device provided by the embodiment of the present invention when it is set at a right angle and not charged, and Figure 14b is a schematic diagram of the charging device provided by the embodiment of the present invention when it is set at a right angle and charged.

As shown in FIG. 14a, the first charging contact portion 15c is, for example, a lock fastener in a right-angle bend shape and can perform a rotational action. The first control board 11 in the first charging device P1 can control the first charging contact portion 15c to rotate and move to the first position in FIG. 14a via the driving unit 13, or the first control board 11 in the first charging device P1 can also control the first charging contact portion 15c to rotate and move to the second position in FIG. 14b via the driving unit 13, that is, at this time, the first charging contact portion 15c is in contact with the second charging contact portion 22c.

It should be noted that, in addition to the aforementioned embodiments, the driving part 13 can be a motor with a telescopic axis, the driving part 13 can also directly control the movement of the first charging contact part 15 or the second charging contact part 22 by directly rotating the motor forward or reverse, the driving part 13 can also attract or release magnetism through an electromagnetic valve, or the driving part 13 can also be a motor plus a lead screw. In short, the driving part 13 can select a relatively suitable driving structure for use according to the different movement modes of the first charging contact part 15 or the second charging contact part 22, but the present invention is not limited to this.
