[0024] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0025] The present application provides a power supply device 10. Figure 1 , Figure 1 A schematic diagram of the application environment of a power supply device 10 provided in one embodiment of the present application. The so-called power supply device 10 is a power supply conversion device for an electronic device 30. Usually, the power supply device 10 can convert an AC voltage into a DC voltage. For example, the power supply device 10 is plugged into an external power supply device 20, receives an AC voltage output by the external power supply device 20, and converts the received AC voltage into a DC voltage, and the DC voltage is used to charge electronic devices 30 such as mobile phones and computers that consume electricity. It can be understood that the schematic diagram of the application environment of the power supply device 10 only helps to understand the application of the power supply device 10, and should not be understood as a limitation of the power supply device 10 provided in the present application. The power supply device provided in the embodiment of the present application may be a power supply device such as a power adapter, a charger, or a charging adapter.

[0026] Figure 2 An exploded schematic diagram of a power supply device provided by an exemplary embodiment of the present application, Figure 3 A partial cross-sectional schematic diagram of a power supply device provided by an exemplary embodiment of the present application, Figure 4 A schematic diagram of a power supply device in a closed state provided by an exemplary embodiment of the present application, Figure 5 The following is a schematic diagram of an open state of a power supply device provided by an exemplary embodiment of the present application. Figure 1-5 As shown, the power supply device 10 includes a device body 11, a cover assembly 110 and a detection module 14. The cover assembly 110 is connected to the device body 11, the cover assembly 110 can move relative to the device body 11, and the cover assembly 110 has an open state and a closed state relative to the device body 11; the detection module 14 is arranged on the device body 11, and the detection module 14 is used to detect whether the cover assembly 110 is connected to the device body 11 when the cover assembly 110 is in an open state.

[0027] The power supply device provided by the embodiment of the present disclosure includes a device body 11, a cover assembly 110 and a detection module 14. The device body 11 and the cover assembly 110 are connected. The cover assembly 110 has an open state and a closed state relative to the device body 11. The detection module 14 detects whether the cover assembly 110 is connected to the device body 11 when the cover assembly 110 is in the open state, so it can be determined whether the cover has fallen off from the device body 11, so that the user can be reminded when the cover has fallen off, thereby avoiding safety hazards caused by insufficient creepage distance when the user uses the power supply device with a fallen cover to charge, thereby improving the safety of charging the power supply device.

[0028] Further, such as Fig. 9 As shown, the power supply device 10 provided in the embodiment of the present disclosure may also include a control module 15, which is connected to the detection module 14. The control module 15 is used to send a prompt signal when the detection module 14 detects that the connection is not in a preset position, and the prompt signal is used to prompt the electronic device 30 that the power supply device 10 is faulty.

[0029] The following is a detailed description of each part of the power supply device 10 provided in the embodiment of the present application:

[0030] The device body 11 refers to the part that realizes the voltage conversion function of the power supply device 10. The device body 11 generally includes a circuit board 112 for voltage conversion. In addition, the device body 11 may also include components such as a housing 111 that accommodates the circuit board 112. The device body 11 is provided with a pin 114, which is used to connect to an external power supply device 20 (for example, a socket).

[0031] The material of the pin 114 is metal, and the pin 114 is plugged into the external power supply device 20 to receive the AC voltage provided by the external power supply device 20. The number of the pins 114 can be, but is not limited to, two. In the present embodiment, the number of the pins 114 is two. The two pins 114 are arranged opposite to each other and at intervals. The pin 114 can be, but is not limited to, a long strip. The end of the pin 114 away from the body of the external power supply device 20 is arc-shaped to facilitate the insertion of the pin 114 into the external power supply device 20. When the pin 114 is inserted into the external power supply device 20 to receive the first voltage, the circuit board 112 is electrically connected to the pin 114 to receive the first voltage transmitted by the pin 114, and the circuit board 112 is used to convert the first voltage into a second voltage.

[0032] In a feasible embodiment, the cover assembly 110 may include an adaptor connector 13 and a cover body 12, wherein the connector 13 is connected to the device body 11; the cover body 12 is connected to the connector 13, and when the cover body 12 moves relative to the device body 11, the connector 13 is driven to move relative to the device body 11, and the detection module 14 is used to ensure that the cover body 12 and the device body 11 are in a connected state when the cover body 12 is in an open state and the connector 13 is in a preset position.

[0033] The preset position is the position relative to the detection module 14 when the cover 112 and the device body 11 are normally connected and the cover 112 is in an open state. When the connector 13 is at the preset position, the distance between the connector 13 and the detection module 14 is within a first preset distance range. For example, when the connector 13 is at the preset position, the distance between the connector 13 and the detection module 14 is less than a first preset distance threshold.

[0034] The pin 114 is exposed on the end face of the device body 11. The cover 12 is connected to the device body 11 through the connector 13 and can rotate relative to the device body 11. The cover 12 has a receiving cavity corresponding to the pin 114. When the cover 12 is in a closed state, the receiving cavity of the cover 12 receives the pin 114. When the cover 12 is in an open state, the surface of the cover 12 facing the pin 114 and the end face of the device body 11 together form the plugging surface of the power supply device 10.

[0035] The receiving cavity of the cover body 12 in the power supply device 10 provided in the present application can accommodate the pin 114, thereby protecting the pin 114 from damage and preventing other objects from being damaged by the pin 114. When the power supply device 10 needs to be used, the cover body 12 is relatively opened to expose the pin 114, and the pin 114 of the power supply device 10 can be inserted into the external power supply device 20. Furthermore, the surface of the cover body 12 facing the pin 114 and the end face of the device body 11 together form the plug-in surface of the power supply device 10, which can ensure that the power supply device 10 has a sufficient creepage distance. Therefore, the thickness of the device body 11 in the power supply device 10 is relatively thin, which is conducive to the miniaturization of the power supply device 10.

[0036] The device body 11 may include a shell 111, a pin base 113 and a circuit board 112, and the shell 111 has an accommodating space; the pin base 113 is connected to the shell 111, and the pin base 113 is used to connect the pin 114. The connector 13 is connected to the base. When the cover 12 is in an open state, the end surface of the pin 114 of the pin base 113 and the end surface of the cover 12 facing the pin 114 form a power plug surface; the circuit board 112 is arranged in the accommodating space, and the detection module 14 is connected to the circuit board 112.

[0037] The shell 111 is made of insulating material, such as plastic, rubber or resin. The shell 111 has a storage space, and the storage space has an opening. For example, the shell 111 can be a rectangular parallelepiped or a structure similar to a rectangular parallelepiped. The shell 111 is a hollow structure, and an opening is provided on one surface of the shell 111.

[0038] The pin base 113 is arranged at the opening of the housing 111, and the end surface of the pin base 113 where the pin 114 is arranged is flush with the end surface of the housing 111 where the opening is located. The pin base 113 is used to connect the pin 114, and the pin 114 can be embedded in the pin base 113. The pin base 113 and the housing 111 can be snap-fit ​​connected, for example, the pin base 113 extends into the accommodating space in the housing 111, and a snap-fit ​​structure is arranged on the surface of the pin 114, and the snap-fit ​​structure is snap-fitted with the housing 111. Alternatively, the pin base 113 and the housing 111 can also be connected by glue connection or the like. For example, the housing 111 and the pin base 113 can be connected by waterproof glue. On the one hand, the waterproof glue is used to connect the housing 111 and the pin base 113, and on the other hand, the waterproof glue can seal the housing 111 to prevent impurities such as external water vapor from entering the housing 111.

[0039] The connector 13 can be connected to the pin base 113. In order to connect the connector 13, a first mounting groove can be provided on the pin base 113, and the connector 13 is connected to the first mounting groove. Accordingly, an avoidance notch is provided on the housing 111 at a position corresponding to the first mounting groove, and the avoidance notch is used to avoid the connector 13.

[0040] The pin base 113 is disposed at the opening of the housing 111, so that the accommodation space in the housing 111 becomes a closed space, and the circuit board 112 is disposed in the closed space. The circuit board 112 is used to set circuit components such as a conversion circuit. The detection module 14 is connected to the circuit board 112 to transmit the detection result of the detection module 14 to the circuit board 112.

[0041] The cover 12 may include a first cover 121 and a second cover 122, and the first cover 121 and the second cover 122 are rotatably connected to the device body 11 through the connecting member 13. When the first cover 121 and the second cover 122 are buckled, the pins 114 are covered; when the first cover 121 and the second cover 122 are relatively opened, the pins 114 are exposed. The detection module 14 detects whether the connecting member 13 connected to the first cover 121 is located at a preset position when the first cover 121 is in an open state, and detects whether the connecting member 13 connected to the second cover 122 is located at a preset position when the second cover 122 is in an open state.

[0042] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above drawings are used to distinguish different objects rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0043] The power supply device 10 has an off state, an on state, and an intermediate state between the off state and the on state. Figure 4 As shown, when the power supply device 10 is in the closed state, the first cover 121 and the second cover 122 are buckled together and completely cover the pins 114. Figure 5 As shown, when the power supply device 10 is in the open state, the first cover 121 and the second cover 122 are both completely open relative to the device body 11, and the pins 114 are completely exposed. When the power supply device 10 is in the intermediate state, the first cover 121 is partially open relative to the device body 11, and the second cover 122 is partially open relative to the device body 11.

[0044] The connector 13 is used to connect the device body 11 and the cover 12. When the cover 12 includes a first cover 121 and a second cover 122, the first cover 121 and the device body 11 can be connected by at least one connector 13. The second cover 122 and the device body 11 can be connected by at least one connector 13.

[0045] like Figure 7 and Figure 8 As shown, the connecting member 13 may include a connecting body 131 and a detecting part 132, the connecting body 131 is respectively connected to the device body 11 and the cover body 12; the detecting part 132 is connected to the connecting body 131, when the cover body 12 is in an open state, the distance between the detecting part 132 and the detecting module 14 is within a first preset distance range, and the detecting part 132 triggers the detecting module 14.

[0046] For example, when the detection unit 132 is located at the preset position, the distance between the detection unit 132 and the detection module 14 is within a first preset distance range. For example, when the distance between the detection unit 132 and the detection module 14 is less than the first preset distance threshold, the detection module 14 is triggered, and when the distance between the detection unit 132 and the detection module 14 is greater than or equal to the first preset distance threshold, the detection module 14 is not triggered. For example, the first preset distance threshold may be 3 mm, 5 mm, 8 mm, or 10 mm, etc.

[0047] Among them, the detection part 132 can be arranged at one end of the connecting body 131 away from the cover body 12. When the cover body 12 rotates relative to the device body 11, the connecting member 13 also moves relative to the device body 11. When the connecting member 13 moves relative to the device body 11, the relative positions of the detection part 132 and the detection module 14 change. When the cover body 12 is in an open state, the detection part 132 triggers the detection module 14, and the detection module 14 sends a signal to the circuit board 112. When the cover body 12 is in a closed state, the detection part 132 does not trigger the detection module 14. When the cover body 12 is in an open state and the detection module 14 cannot detect the detection part 132, it can be determined that the cover body 12 falls off. In actual applications, a cover opening detection device can also be provided in the power supply device 10, and the cover opening detection device is used to detect whether the cover body 12 is in an open state, a closed state or an intermediate state.

[0048] The connecting body 131 includes: a connecting part 1311, a first connecting axis 1312 and a second connecting axis 1313; the first connecting axis 1312 is passed through the connecting part 1311, and the first connecting axis 1312 is connected to the cover body 12; the second connecting axis 1313 is passed through the connecting part 1311, and the second connecting axis 1313 is connected to the device body 11; the detecting part 132 is arranged at one end of the connecting part 1311 away from the cover body 12.

[0049] One end of the connecting portion 1311 can be connected to the first mounting slot on the pin base 113 via a first connecting shaft 1312. A second mounting slot can be provided at a corresponding position on the cover 12, and the other end of the connecting portion 1311 can be connected to the second mounting slot via a second connecting shaft 1313.

[0050] The connecting portion 1311 and the pin base 113 are connected via the first connecting shaft 1312, that is, the connecting portion 1311 and the pin base 113 can rotate around the first connecting shaft 1312. The detecting portion 132 is disposed at one end of the connecting portion 1311 away from the cover body 12, so the detecting portion 132 is located inside the pin base 113, and an escape space is provided inside the pin base 113, and the escape space is used to prevent the detecting portion 132 and the pin base 113 from interfering with each other during the movement process.

[0051] For example, the connecting portion 1311 may be a connecting rod, on which a first through hole and a second through hole are provided, wherein the first through hole is used to penetrate the first connecting shaft 1312, and the second through hole is used to penetrate the second connecting shaft 1313. The detecting portion 132 rotates around the second connecting shaft 1213, and when the cover body is in a closed state, the detecting portion 132 is not opposite to the detecting module 14 (that is, the detecting portion is outside the detecting range of the detecting module); when the cover body is in an open state, the detecting portion 132 is opposite to the detecting module 14 (that is, the detecting portion is within the detecting range of the detecting module). The detecting portion 132 may be a raised portion or an extended portion provided on the connecting rod away from one end of the cover body 12. The connecting portion 1311 and the detecting portion 132 may be an integral structure or a split structure.

[0052] In practical applications, the detection parts 132 may also be respectively provided at both ends of the connection part 1311 , so as to increase the convenience of installation.

[0053] It is understandable that in the disclosed embodiment, the connecting member 13 may include a connecting shaft and a trigger block, the connecting shaft may be rotatably connected to the device body 11, and the connecting shaft and the cover body 12 are fixedly connected, and the trigger block and the connecting shaft are fixedly connected. When the cover body 12 rotates relative to the device body 11, the connecting shaft and the trigger block also rotate. A trigger notch may be provided on the device body 11, and when the cover body 12 is in a closed state, the trigger block is located in the trigger notch, and when the cover body 12 is in an open state, the trigger block rotates out of the trigger notch.

[0054] When the detection module 14 is a distance sensor, when the cover 12 is in the open state, the trigger block rotates out of the trigger notch and faces the distance sensor, that is, the trigger block is located on the path of the detection light emitted by the distance sensor. When the detection module 14 is a Hall sensor, a magnet can be provided in the trigger block, and the distance between the magnet and the Hall sensor can be adjusted by rotating to detect whether the cover 12 is connected to the device body 11.

[0055] The pin base 113 may include a top plate and a side plate, and the pin 114 may be embedded in the top plate. The side plate is an annular structure, and one end face of the annular structure is connected to the top plate. An opening is provided on one end face of the annular side plate away from the top plate, and the annular side plate and the top plate form an escape space. In order to connect the pin 114 or to enhance the strength, a connecting rib or a reinforcing rib or other structures may be provided in the escape space, and the connecting rib and the reinforcing rib do not interfere with the detection unit 132.

[0056] For example, the first cover 121 and the device body 11 can be connected by two connectors 13. The second cover 122 and the device body 11 are connected by two connectors 13. That is, four first mounting grooves can be provided on the pin base 113, two second mounting grooves can be provided on the first cover 121, and two second mounting grooves can be provided on the second cover 122.

[0057] When the first cover 121 is in the open state, the detection portion 132 of one connector 13 connected to the first cover 121 is located at the first preset position, and the detection portion 132 of another connector 13 connected to the first cover 121 is located at the second preset position. When the second cover 122 is in the open state, the detection portion 132 of one connector 13 connected to the second cover 122 is located at the third preset position, and the detection portion 132 of another connector 13 connected to the second cover 122 is located at the fourth preset position.

[0058] When the first cover 121 and the second cover 122 are in the open state, the detection module 14 detects whether the detection parts 132 in the above-mentioned four connecting members 13 are respectively located at the first preset position, the second preset position, the third preset position and the fourth preset position. When at least one of the detection parts 132 in the above-mentioned four connecting members 13 is not in the preset position, it is considered that the cover 12 is detached from the device body 11.

[0059] The detection module 14 is disposed on the device body 11 and is used to detect whether the connector 13 is located at a preset position when the cover 12 is in an open state. The detection module 14 can work when the cover 12 is in an open state, and can not work when the cover 12 is in a closed state.

[0060] The detection module 14 can be disposed on the pin base 113, and the detection module 14 and the detection portion 132 are disposed opposite to each other. When the cover 12 is in an open state and the cover 12 is not dropped off, the detection module 14 can detect the detection portion 132 at a preset position. When the cover 12 is in an open state and the cover 12 is dropped off, the detection module 14 cannot detect the detection portion 132 at a preset position.

[0061] The detection result signal obtained by the detection module 14 needs to be transmitted to the main board, so the detection module 14 is electrically connected to the main board. In a feasible embodiment of the present disclosure, the detection module 14 may include: a support member 142 and a detector 141, one end of the support member 142 is connected to the circuit board 112, and the other end of the support member 142 is opposite to the pin base 113; the detector 141 is arranged on a side of the support member 142 away from the circuit board 112.

[0062] The detector 141 may be a distance sensor 1411, which is disposed on a side of the support member 142 away from the circuit board 112, and when the cover 12 is in an open state, the distance sensor 1411 and the detection unit 132 are opposite, and a detection channel is provided between the distance sensor 1411 and the detection unit 132, and when the distance sensor 1411 detects that the distance from the detection unit 132 to the distance sensor 1411 is within a first preset distance range, it is determined that the detection unit 132 is located at a preset position. The detection channel means that when the cover 12 is in an open state, there is no obstacle between the distance sensor and the detection unit 132.

[0063] One end of the support member 142 away from the circuit board 112 can extend into the pin base 113, that is, the distance sensor 1411 can be disposed in the pin base 113. Figure 6 As shown, when the cover 12 is in the open state, the distance sensor 1411 and the detection unit 132 are opposite. At this time, the distance between the distance sensor and the detection unit 132 is a certain value, for example, the distance between the distance sensor and the detection unit 132 is a first distance value. During the detection process, it can be detected in real time whether there is an obstacle at the position of the first distance value from the distance sensor 1411. If there is an obstacle at the position of the first distance value from the distance sensor 1411, the cover 12 has not fallen off. If there is no obstacle at the position of the first distance value from the distance sensor 1411, the cover 12 has fallen off.

[0064] It is worth noting that in the embodiment of the present disclosure, when the cover 12 is in the open state, the distance sensor 1411 and the corresponding detection part 132 have a detection channel, that is, there is an air gap between the distance sensor 1411 and the corresponding detection part, and there is no other device isolation.

[0065] When a partition is provided on the pin base 113 and is located between the distance sensor 1411 and the detection unit 132 , a notch is provided on the partition at a position opposite to the distance sensor. When the cover 12 is in an open state, the detection unit 132 is exposed to the notch.

[0066] The support member 142 extends from the circuit board 112 to the pin base 113, and the distance sensor 1411 can be connected to the support member 142 by glue connection or plug-in connection. A signal line can be provided on the support member 142, and the signal line connects the distance sensor 1411 and the circuit board 112 respectively, and transmits the signal detected by the distance sensor 1411 to the circuit board 112. The support member 142 can be made of insulating material, for example, the material of the support member 142 can be plastic, resin or ceramic.

[0067] For example, the distance sensor 1411 can be an infrared distance sensor, which can include an infrared transmitter and an infrared receiver. The infrared transmitter transmits infrared rays, which are reflected after encountering an obstacle, and the reflected infrared rays are received by the infrared receiver. The distance between the infrared distance sensor and the obstacle can be determined based on the transmission time and the reception time.

[0068] It is understandable that if Fig.10 As shown, the detector 141 can also be a Hall sensor 1412, which is arranged on the side of the support member 142 away from the circuit board 112; at this time, a magnetic member (not shown in the figure) is arranged on the detection part 132, and the Hall sensor 1412 detects whether the connecting member 13 is located at the preset position by detecting the position of the magnetic member on the detection part 132.

[0069] The Hall sensor 1412 can detect the surrounding magnetic field, and the magnetic part provided in the connecting part 1311 has a magnetic field. According to the magnitude of the magnetic field strength detected by the Hall sensor 1412, the distance between the Hall sensor 1412 and the detection part 132 can be determined. When the cover 12 is in an open state, the distance between the detection part 132 and the Hall sensor 1412 is a certain value, that is, the magnetic field strength detected by the Hall sensor 1412 is a certain value. For example, when the cover 12 is in an open state, the magnetic field strength detected by the Hall sensor 1412 is a first strength. At this time, when the cover 12 is in an open state, the magnetic field strength detected by the Hall sensor 1412 is consistent with the first strength, then it is considered that the cover 12 has not fallen off; when the cover 12 is in an open state, the magnetic field strength detected by the Hall sensor 1412 is inconsistent with the first strength, then it is considered that the cover 12 has fallen off.

[0070] The support member 142 extends from the circuit board 112 to the pin base 113, and the Hall sensor 1412 can be connected to the support member 142 by glue connection or plug-in connection. A signal line can be provided on the support member 142, and the signal line connects the Hall sensor 1412 and the circuit board 112 respectively, and transmits the signal detected by the Hall sensor 1412 to the circuit board 112. The support member 142 can be made of insulating material, for example, the material of the support member 142 can be plastic, resin or ceramic.

[0071] The magnetic member may be a permanent magnet, and the magnetic member is embedded in the detection part 132. For example, the connecting member 13 is a plastic connecting member 13, and the connecting member 13 is formed by injection molding, and the magnetic member is embedded in the detection part 132 during injection molding. Alternatively, the detection part 132 may be formed by a magnetic member, that is, the detection part 132 is a magnetic member connected to the connection part 1311.

[0072] It is understandable that the detection module 14 may include a flexible circuit board 112 and a detector 141. The detector 141 is connected to the pin base 113, one end of the flexible circuit board 112 is connected to the detector 141, and the other end of the flexible circuit board 112 is connected to the circuit board 112, so as to realize the electrical connection between the circuit board 112 and the detector 141.

[0073] The detector 141 can be a distance sensor 1411, which is arranged on the pin base 113, and when the cover 12 is in an open state, the distance sensor 1411 and the detection part 132 are opposite to each other, and a detection channel is provided between the distance sensor 1411 and the detection part 132, and the distance sensor 1411 detects the distance from the detection part 132 to the distance sensor 1411.

[0074] One end of the flexible circuit board 112 away from the circuit board 112 can extend into the pin base 113 and connect to the distance sensor 1411 disposed in the base. The distance sensor 1411 can be disposed on the inner wall of the side plate of the pin base 113, or the distance sensor 1411 can be disposed on the partition in the pin base 113. At this time, the distance between the distance sensor and the detection unit 132 is a certain value, for example, the distance between the distance sensor and the detection unit 132 is a first distance value. During the detection process, it can be detected in real time whether there is an obstacle at the position of the first distance value from the distance sensor 1411. If there is an obstacle at the position of the first distance value from the distance sensor 1411, the cover body 12 has not fallen off. If there is no obstacle at the position of the first distance value from the distance sensor 1411, the cover body 12 has fallen off.

[0075] It is worth noting that in the embodiment of the present disclosure, when the cover 12 is in the open state, the distance sensor 1411 and the corresponding detection part 132 have a detection channel, that is, there is an air gap between the distance sensor 1411 and the corresponding detection part, and there is no other device isolation.

[0076] Among them, when the distance sensor 1411 is arranged on the side plate of the pin base 113, and a partition is arranged on the pin base 113 between the distance sensor 1411 and the detection part 132, a notch is arranged on the partition at a position opposite to the distance sensor, and when the cover body 12 is in an open state, the detection part 132 is exposed to the notch.

[0077] The distance sensor 1411 can be connected to the pin base 113 by glue connection or plug connection. A signal line can be provided on the flexible circuit board 112, and the signal line connects the distance sensor 1411 and the circuit board 112 respectively to transmit the signal detected by the distance sensor 1411 to the circuit board 112.

[0078] It is understandable that the detector 141 can also be a Hall sensor 1412, which is disposed on the pin base 113; in this case, a magnetic member is disposed on the detection portion 132, and the Hall sensor 1412 detects whether the connector 13 is located at a preset position by detecting the position of the magnetic member on the detection portion 132.

[0079] The Hall sensor 1412 can detect the surrounding magnetic field, and the magnetic part provided in the connecting part 1311 has a magnetic field. According to the magnitude of the magnetic field strength detected by the Hall sensor 1412, the distance between the Hall sensor 1412 and the detection part 132 can be determined. When the cover 12 is in an open state, the distance between the detection part 132 and the Hall sensor 1412 is a certain value, that is, the magnetic field strength detected by the Hall sensor 1412 is a certain value. For example, when the cover 12 is in an open state, the magnetic field strength detected by the Hall sensor 1412 is a first strength. At this time, when the cover 12 is in an open state, the magnetic field strength detected by the Hall sensor 1412 is consistent with the first strength, then it is considered that the cover 12 has not fallen off; when the cover 12 is in an open state, the magnetic field strength detected by the Hall sensor 1412 is inconsistent with the first strength, then it is considered that the cover 12 has fallen off.

[0080] The flexible circuit board 112 extends from the circuit board 112 to the pin base 113 . A signal line may be provided on the flexible circuit board 112 . The signal line is respectively connected to the Hall sensor 1412 and the circuit board 112 to transmit the signal detected by the Hall sensor 1412 to the circuit board 112 .

[0081] Of course, in practical applications, when the detector 141 is a Hall sensor 1412 , the Hall sensor 1412 may also be connected to the circuit board 112 or the housing 111 , but the embodiments of the present disclosure are not limited thereto.

[0082] It should be noted that in the embodiment of the present disclosure, when the detection module 14 is a distance sensor, the distance between the detection unit 132 and the detection module 14 in the phrase “when the detection unit 132 is located at the preset position, the distance between the detection unit 132 and the detection module 14 is within a first preset distance range” refers to the distance from the detection unit 132 to the optical axis of the detection light emitted by the distance sensor. When the detection module 14 is a Hall sensor, the distance between the detection unit 132 and the detection module 14 in the phrase “when the detection unit 132 is located at the preset position, the distance between the detection unit 132 and the detection module 14 is within a first preset distance range” refers to the distance from the detection unit to the Hall sensor.

[0083] In another feasible embodiment of the present disclosure, the detection module 14 can also determine whether the cover assembly 110 is connected to the device body by detecting whether the cover 12 is in place. When the cover 12 is in an open state, the distance between the side of the cover 12 facing the device body 11 and the device body 11 is within a second preset distance range; when the detection module 14 detects that the distance between the side of the cover 12 facing the device body 11 and the device body 11 is within the second preset distance range, it is determined that the cover assembly 110 is connected to the device body 11. For example, when the detection module 14 detects that the distance between the side of the cover 12 facing the device body 11 and the device body 11 is less than the second preset distance threshold, it is determined that the cover assembly 110 is connected to the device body 11.

[0084] Among them, when the cover body 12 is in an open state, the side of the cover body 12 facing the device body 11 is in contact with the device body 11. At this time, the detection module 14 may include a contact sensor, a distance sensor or a pressure sensor. That is, the side of the detection body 12 facing the device body 11 is in contact with the device body 11 through a contact sensor, a distance sensor or a pressure sensor. At this time, the second preset distance threshold is 0. Alternatively, a Hall sensor and a magnet can be used, for example, a magnet is set on the cover body 12, and a Hall sensor is set on the device body 11. At this time, the second preset distance threshold can be 1 mm, 2 mm or 3 mm, etc.

[0085] The control module 15 is connected to the detection module 14 . The control module 15 is used to send a prompt signal when the detection module 14 detects that the connection is not at a preset position. The prompt signal is used to prompt the electronic device 30 that the power supply device 10 is faulty.

[0086] The control module 15 may include a processing unit 151 and a communication unit 152, and the processing unit 151 is connected to the detection module 14. The processing unit 151 is used to determine whether the cover 12 falls off according to the detection result of the detection module 14, and the communication unit 152 is connected to the processing unit 151, and the communication unit 152 is used to send a prompt signal to the electronic device 30 when the cover 12 falls off.

[0087] For example, when the detection module 14 is a distance sensor 1411, the processing unit 151 determines the position of the obstacle detected by the distance sensor 1411 according to the electrical signal sent by the distance sensor 1411. If the position of the obstacle is consistent with the preset position of the detection unit 132, it is considered that the cover 12 has not fallen off; if the position of the obstacle is different from the preset position of the detection unit 132, it is considered that the cover 12 has fallen off. When the detection module 14 is a Hall sensor 1412, the processing unit 151 determines the magnetic field strength detected by the Hall sensor 1412 according to the electrical signal sent by the Hall sensor 1412, and determines whether the detection unit 132 is in the preset position according to the magnetic field strength. If the magnetic field strength detected by the Hall sensor 1412 is consistent with the preset strength, it is considered that the cover 12 has not fallen off; if the magnetic field strength detected by the Hall sensor 1412 is inconsistent with the preset strength, it is considered that the cover 12 has fallen off.

[0088] The communication unit 152 may be a wired communication unit 152 or a wireless communication unit 152, and the wired communication unit 152 may be connected to the electronic device 30 via a data line. The wireless communication unit 152 may be a Bluetooth unit, an infrared unit, a WiFi unit, or an NFC unit.

[0089] The power supply device 10 provided in the embodiment of the present disclosure includes a device body 11, a cover assembly 110 and a detection module 14. The device body 11 and the cover assembly 110 are connected. The cover assembly 110 has an open state and a closed state relative to the device body 11. The detection module 14 detects whether the cover assembly 110 is connected to the device body 11 when the cover assembly 110 is in the open state, so it can be determined whether the cover has fallen off from the device body 11, so that the user can be reminded when the cover has fallen off, thereby avoiding safety hazards caused by insufficient creepage distance when the user uses the power supply device with a fallen cover to charge, thereby improving the safety of charging the power supply device.

[0090] Furthermore, the receiving cavity of the cover body 12 in the power supply device 10 can receive the pin 114, thus protecting the pin 114 from damage and preventing other objects from being damaged by the pin 114. When the power supply device 10 needs to be used, the cover body 12 is relatively opened to expose the pin 114, and the pin 114 of the power supply device 10 can be inserted into the external power supply device 20. Furthermore, the surface of the cover body 12 facing the pin 114 and the end face of the device body 11 together form the plug-in surface of the power supply device 10, which can ensure that the power supply device 10 has a sufficient creepage distance. Therefore, the thickness of the device body 11 in the power supply device 10 is relatively thin, which is conducive to the miniaturization of the power supply device 10.

[0091] The exemplary embodiment of the present disclosure further provides an electronic device system, which includes the power supply device 10 and the electronic device 30 . The power supply device 10 is used to charge the electronic device 30 .

[0092] The electronic device 30 may be a mobile phone, a tablet computer, an e-reader, a laptop computer, a smart watch, a mobile power source, a pair of smart glasses, or other drones. The electronic device 30 may include a charging interface and a battery, wherein the charging interface is used to connect to the power supply device 10 and receive a power signal. The battery is connected to the charging interface, and the battery is used to store electrical energy and provide electrical energy to power-consuming devices in the electronic device 30.
