Description

Technical Field

[0001] This application relates to the field of charging technology, and more particularly to a charger. Background Technology

[0002] A charger is a device that connects an electrical appliance to a power source, allowing the appliance to be charged. To charge an appliance using a charger, the charger's prongs must be plugged into the socket of a power outlet to establish an electrical connection.

[0003] However, in related technologies, chargers typically have a single charging mode, which makes it difficult to meet the charging needs of electrical devices under different usage conditions. Utility Model Content

[0004] This application provides a charger that can operate in different charging modes, thereby meeting the charging needs of electrical devices under different usage conditions.

[0005] A charger, comprising: The protective shell includes a first shell and a second shell movably connected to the first shell; An electronic control component is installed inside the first housing, and the electronic control component has a current output terminal; Multiple pins connect to the second housing; A circuit assembly is disposed within the protective housing. The circuit assembly includes a first conductive structure and a second conductive structure. One of the first conductive structure and the second conductive structure is disposed in the first housing and electrically connected to the electronic control component. The other of the first conductive structure and the second conductive structure is disposed in the second housing and electrically connected to the pin. The first housing and the second housing are movable relative to each other to make the first conductive structure and the second conductive structure conduct or disconnect, thereby making the pin conduct or disconnect from the electronic control component. A triggering component is disposed on the protective shell. The triggering component is electrically connected to the electronic control component. The triggering component is used to send a position signal to the electronic control component according to the position of the first conductive structure. The first conductive structure has at least one power-off position and multiple working positions on its movable trajectory. When the first conductive structure is located at the power-off position, the first conductive structure is disconnected from the second conductive structure, so that the pin is disconnected from the electronic control component. When the first conductive structure is in the working position, the first conductive structure is connected to the second conductive structure, so that the pin is connected to the electronic control component; and when the first conductive structure is in different working positions, the current output terminal of the electronic control component is used to output the current corresponding to the position signal according to the position signal, so that the charger is in different charging modes.

[0006] The beneficial effects of this application are as follows: When using the charger, before the plug is inserted into the socket, the user can apply external force to the first and second housings with their hand or other tools. This causes the first and second housings to move relative to each other under the action of the external force, thereby disconnecting the first conductive structure from the second conductive structure, and consequently disconnecting the plug from the electronic control components. When the plug is inserted into the socket, the plug and the power supply will not form a current circuit, and no voltage exceeding the air breakdown threshold will be generated between the plug and the metal conductor of the power socket, thus preventing arcing during the insertion of the plug. After the plug is inserted into the socket, the first and second housings move relative to each other, causing the first and second conductive structures to conduct. Since both the first and second conductive structures are located within the protective shell, even if arcing occurs at the moment of conduction between the first and second conductive structures, the sparks generated are difficult for the user to detect, thereby eliminating the discomfort caused by the sparks. In addition, the charging mode of the charger can be switched by the relative movement of the first and second housings, so that the charger can work in different charging modes and thus meet the charging needs of electrical equipment under different usage conditions.

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0011] A charger is a device that connects an electrical appliance to a power source, allowing the appliance to be charged. To charge an appliance using a charger, the charger's prongs must be plugged into the socket of a power outlet to establish an electrical connection.

[0012] However, in related technologies, on the one hand, when the pins are inserted into the socket and the pins are not in complete contact with the metal conductor in the socket, the tiny gap between the pins and the metal conductor will form an "air insulation layer". When the voltage difference between the pins and the metal conductor exceeds the air breakdown threshold, the air molecules will be ionized into plasma, resulting in an arcing phenomenon. The sparks produced by the arcing can easily cause discomfort.

[0013] On the other hand, chargers typically have a single charging mode, which makes it difficult to meet the charging needs of electrical devices under different usage conditions.

[0014] In view of the above-mentioned technical problems, this application provides a charger, such as Figure 1 and Figure 2 As shown, the charger includes a protective case 10, an electronic control component 20, multiple pins, and a circuit component 40.

[0015] The protective shell 10 includes a first shell 11 and a second shell 12 movably connected to the first shell 11. The protective shell 10 is a protective shell for the charger and can be formed of insulating material.

[0016] The electronic control component 20 is installed inside the first housing 11. The electronic control component 20 has a current output terminal and can realize electronic control between the power supply and the device when the device is connected to the power source via a charger. It is understood that when the charger is a wired charger, it may also include a power interface 60 such as a USB interface, Type-C interface, or Lightning interface located in the protective housing 10. In this case, the output terminal of the electronic control component 20 is electrically connected to the power interface 60, which can be electrically connected to the device via a charging cable. The output terminal outputs current to the power interface 60, allowing the device to receive the current. When the charger is a wireless charger, it also includes a charging coil located inside the protective housing 10. The output terminal of the electronic control component 20 is electrically connected to the charging coil, outputting current to it. The charging coil generates electromagnetic waves, which propagate energy. The electromagnetic wave energy transmitted by the charging coil can be converted into electrical energy for the device, thus providing wireless charging for the device.

[0017] Multiple prongs are connected to the second housing 12. The prongs are made of conductive materials such as metal and can be inserted into the socket of a power outlet so that a charger can be used to draw power.

[0018] The circuit assembly 40 is disposed within the protective housing 10. The circuit assembly 40 includes a first conductive structure 41 and a second conductive structure 42. One of the first conductive structure 41 and the second conductive structure 42 is disposed in the first housing 11 and electrically connected to the electronic control assembly 20. The other of the first conductive structure 41 and the second conductive structure 42 is disposed in the second housing 12 and electrically connected to the pin. The first housing 11 and the second housing 12 are movable relative to each other so that the first conductive structure 41 and the second conductive structure 42 are connected or disconnected, thereby making the pin connected or disconnected from the electronic control assembly 20.

[0019] It is understood that the first housing 11 and the second housing 12 can rotate relative to each other under the action of an external force (such as an external force provided by the user's hand), thereby allowing the first conductive structure 41 and the second conductive structure 42 to move relative to each other. This allows the first conductive structure 41 to be connected to or disconnected from the second conductive structure 42. Since the electronic control component 20 and the pins are connected and disconnected through the first conductive structure 41 and the second conductive structure 42, the connection and disconnection between the electronic control component 20 and the pins can be achieved through the relative movement of the first housing 11 and the second housing 12. The first conductive structure 41 and the second conductive structure 42 can be electrically connected to the electronic control component 20 through conductive wires.

[0020] It should also be noted that when using the charger, before inserting the plug into the socket of the power outlet, the user can use their hand or other tools to apply external force to the first housing 11 and the second housing 12, so that the first housing 11 and the second housing 12 move relative to each other under the action of external force, thereby disconnecting the first conductive structure 41 from the second conductive structure 42, and thus disconnecting the plug from the electronic control component 20. When the plug is inserted into the socket of the power outlet, the plug and the power supply will not form a power circuit, and no voltage of the air breakdown threshold will be generated between the plug and the metal conductor of the power outlet, so that no arcing will occur during the insertion of the plug into the socket.

[0021] When the pins are inserted into the socket, the first housing 11 and the second housing 12 move relative to each other, thereby making the first conductive structure 41 and the second conductive structure 42 conductive. Since both the first conductive structure 41 and the second conductive structure 42 are located inside the protective housing 10, even if sparking occurs at the moment the first conductive structure 41 and the second conductive structure 42 are conductive, the sparks generated by the sparking are difficult for the user to detect, thus eliminating the discomfort caused by the sparks generated by the sparking. In addition, since the first conductive structure 41 and the second conductive structure 42 are conductive inside the protective housing 10, the protective housing 10 can play an insulating protection role, preventing the sparks generated by the sparking from coming into contact with the user and reducing the risk of electric shock.

[0022] It is also worth mentioning that users can drive the first conductive structure 41 and the second conductive structure 42 to move relative to each other by operating the first housing 11 and / or the second housing 12 outside the protective case 10, thereby realizing the switching on and off of the first conductive structure 41 and the second conductive structure 42. This allows users to maintain good insulation protection with the first conductive structure 41 and the second conductive structure 42 during the use of the charger, further improving the safety when using the charger.

[0023] Specifically, the charger also includes a trigger component 50, which is disposed on the protective shell 10 and electrically connected to the electronic control component 20. The trigger component 50 is used to send a position signal to the electronic control component 20 according to the position of the first conductive structure 41.

[0024] The movable trajectory of the first conductive structure 41 has at least one de-energized position (e.g., Figure 3 and Figure 4 ) and multiple work locations (such as Figure 1 and Figure 2 When the first conductive structure 41 is in the de-energized position, the first conductive structure 41 is disconnected from the second conductive structure 42, thereby disconnecting the pin from the electronic control component 20. The first conductive structure 41 may have one, two, or more de-energized positions; and the first conductive structure 41 may have two, three, or more operational positions.

[0025] When the first conductive structure 41 is in the working position, it is connected to the second conductive structure 42, thereby connecting the pins to the electronic control component 20. When the first conductive structure 41 is in different working positions, the current output terminal of the electronic control component 20 outputs a current corresponding to the position signal, thus enabling the charger to operate in different charging modes. It is understood that the relative movement of the first housing 11 and the second housing 12 changes the relative positional relationship between the first conductive structure 41 and the second conductive structure 42, allowing the first conductive structure 41 to move between different positions. When the first conductive structure 41 is in any working position, it is connected to the second conductive structure 42, thereby connecting the pins to the electronic control component 20.

[0026] It should also be noted that, taking the example of multiple working positions, including a first working position and a second working position, with the plug inserted into the socket of the power outlet, the electrical device being electrically connected to the output terminal of the electrical control component 20, and the electrical device being electrically connected to the power supply via a charger: When the first housing 11 and the second housing 12 move relative to each other, causing the first conductive structure 41 to be in the first working position, the trigger component 50 detects that the first conductive structure 41 is in the first working position and sends a position signal (first position signal) corresponding to the first working position to the electronic control component 20. The electronic control component 20 receives the power supply current and outputs the power current (first power current) corresponding to the first position signal to the power-consuming device through the output terminal, so that the charger is in the corresponding charging mode (first charging mode) to work. The specific value of the first power current can be selected according to actual needs.

[0027] When the first housing 11 and the second housing 12 move relative to each other, causing the first conductive structure 41 to be in the second working position, the trigger component 50 detects that the first conductive structure 41 is in the second working position and sends a position signal (second position signal) corresponding to the second working position to the electronic control component 20. The electronic control component 20 receives the power supply current and outputs the power current (second power current) corresponding to the second position signal to the power-consuming device through the output terminal, so that the charger is in the corresponding charging mode (second charging mode) to work. The specific value of the second power current can be selected according to actual needs.

[0028] It is understood that in this application, the charging mode of the charger can be switched by the relative movement of the first housing 11 and the second housing 12, so that the charger can work in different charging modes, thereby meeting the charging needs of the electrical device under different usage conditions. For example, the first charging mode is a fast charging mode and the second charging mode is a slow charging mode. At this time, the first current consumption is greater than the second current consumption. When the electrical device needs fast charging, the charger can be switched to the first charging mode; when the electrical device needs slow charging, the charger can be switched to the second charging mode.

[0029] It should also be noted that the charger can have two, three or more charging modes, with one working position corresponding to one mode; for example, the charger can also have a third charging mode, and the movable trajectory of the first conductive structure 41 also has a third working position. When the first conductive structure 41 is in the second working position, the output terminal of the electronic control component 20 outputs a third current, and the charger is in the third charging mode. The third charging mode can be a user-defined mode, and the user can select the third current of the third charging mode according to their usage habits.

[0030] In some embodiments, the first housing 11 and the second housing 12 are disposed opposite to each other and are connected by a pivot 13 (e.g., Figure 4The first housing 11 and the second housing 12 are rotatably connected, allowing them to rotate relative to each other around the axis of the rotating shaft 13. This enables the first conductive structure 41 and the second conductive structure 42 to rotate relative to each other around the axis of the rotating shaft 13, thereby enabling the first conductive structure 41 and the second conductive structure 42 to switch on and off.

[0031] It should also be noted that in other embodiments, the first housing 11 and the second housing 12 can also be connected in other ways. For example, the first housing 11 can be slidably connected to the second housing 12, and the first housing 11 and the second housing 12 can slide relative to each other along their arrangement direction, so that the first conductive structure 41 and the second conductive structure 42 can slide relative to each other, thereby realizing the connection and disconnection of the first conductive structure 41 and the second conductive structure 42. In other embodiments, the first housing 11 and the second housing 12 can also be connected in a detachable manner. When the pin is inserted into the socket, the first housing 11 and the second housing 12 are in a separated state, and the first conductive structure 41 and the second conductive structure 42 are disconnected. Subsequently, the first housing 11 and the second housing 12 can be connected by snap-fit, magnetic connection, threaded connection or other means, so that the first conductive structure 41 and the second conductive structure 42 are conductive.

[0032] See also Figures 1 to 4 As shown, in some embodiments of this application, multiple pins include a positive pin 31 and a negative pin 32. A first conductive structure 41 includes a positive conductive contact 411 and a negative conductive contact 412. A second conductive structure 42 includes a positive connection contact 421 and a negative connection contact 422. The positive conductive contact 411 and the positive connection contact 421 are used to connect / disconnect the positive pin 31 with the electronic control component 20, and the negative conductive contact 412 and the negative connection contact 422 are used to connect / disconnect the negative pin 32 with the electronic control component 20. It can be understood that the positive pin 31 is used for electrical connection to the positive terminal of the power supply, and the negative pin 32 is used for electrical connection to the negative terminal of the power supply. When the first conductive structure 41 is disposed on the first housing 11, the second conductive structure 42 is disposed on the second housing 12. At this time, both the positive conductive contact 411 and the negative conductive contact 412 are electrically connected to the electronic control component 20, the positive connecting contact 421 is electrically connected to the positive pin 31, and the negative connecting contact 422 is electrically connected to the negative pin 32. When the first conductive structure 41 is disposed on the second housing 12, the second conductive structure 42 is disposed on the first housing 11. At this time, both the positive conductive contact 411 and the positive pin 31 are electrically connected, the negative conductive contact 412 is electrically connected to the negative pin 32, and both the positive connecting contact 421 and the negative connecting contact 422 are electrically connected to the pins of the electronic control component 20.

[0033] Among them, such as Figure 1 and Figure 2As shown, when the first conductive structure 41 is in the working position, the positive conductive contact 411 is connected to the positive terminal contact 421, and the negative conductive contact 412 is connected to the negative terminal contact 422, so that the first conductive structure 41 and the second conductive structure 42 are connected, thereby forming a conductive circuit between the positive terminal pin 31, the electronic control component 20 and the negative terminal pin 32. Only when the pin is inserted into the socket can arcing occur.

[0034] In some embodiments, such as Figure 3 and Figure 4 As shown, when the first conductive structure 41 is in the de-energized position, the positive conductive contact 411 is disconnected from the positive contact 421, or the negative conductive contact 412 is disconnected from the negative contact 422, so that the first conductive structure 41 is disconnected from the second conductive structure 42. It is understood that in this embodiment, when the positive conductive contact 411 is disconnected from the positive connection contact 421 or the negative conductive contact 412 is disconnected from the negative connection contact 422, the positive pin 31, the electronic control component 20, and the negative pin 32 cannot form a conductive circuit. At this time, the pin will not spark when inserted into the socket. In this embodiment, only the positive conductive contact 411 and the positive connection contact 421 can be disconnected, while the negative conductive contact 412 and the negative connection contact 422 remain in a conductive state. Alternatively, only the negative conductive contact 412 and the negative connection contact 422 can be disconnected, while the positive conductive contact 411 and the positive connection contact 421 remain in a conductive state.

[0035] In other embodiments, when the first conductive structure 41 is in the de-energized position, the positive conductive contact 411 is disconnected from the positive terminal contact 421, and the negative conductive contact 412 is disconnected from the negative terminal contact 422, thereby disconnecting the first conductive structure 41 from the second conductive structure 42. In this embodiment, it is necessary to simultaneously control the positive conductive contact 411 to disconnect from the positive terminal contact 421, and the negative conductive contact 412 to disconnect from the negative terminal contact 422.

[0036] In some embodiments, at least one of the positive terminal contact 421 and the negative terminal contact 422 may be a conductive pin, and at least one of the positive terminal conductive contact 411 and the negative terminal conductive contact 412 may be a conductive spring pin. Of course, in other embodiments, the positive terminal contact 421, the negative terminal contact 422, the positive terminal conductive contact 411, and the negative terminal conductive contact 412 may also be conductive springs.

[0037] like Figures 5 to 7As shown, in some embodiments, multiple second conductive structures 42 are provided, and the multiple second conductive structures 42 are arranged at intervals along the relative movement direction XX of the first housing 11 and the second housing 12. When the first conductive structure 41 is in different working positions, the first conductive structure 41 is connected to different second conductive structures 42. It can be understood that when the first conductive structure 41 is in different working positions, it contacts and connects with different second conductive structures 42, thereby ensuring that the pins of the first conductive structure 41 can be connected to the electronic control component 20 in each position. For example, when the first conductive structure 41 is in the first working position, the first conductive structure 41 can contact and connect with one second conductive structure 42, thereby making the pins connected to the electronic control component 20; when the first conductive structure 41 is in the second working position, the first conductive structure 41 can contact and connect with another second conductive structure 42, thereby making the pins connected to the electronic control component 20. When the first conductive structure 41 is in the de-energized position, the first conductive structure 41 can be located in the gap between two adjacent second conductive structures 42, so that the first conductive structure 41 can be separated from and disconnected from all the second conductive structures 42.

[0038] It should also be noted that when the second conductive structure 42 is disposed on the first housing 11, the plurality of second conductive structures 42 are electrically connected to the electronic control component 20; when the second conductive structure 42 is disposed on the second housing 12, the plurality of second conductive structures 42 are electrically connected to the pins. When the first housing 11 and the second housing 12 are rotatably connected by the rotating shaft 13, the plurality of second conductive structures 42 are arranged at intervals around the outer periphery of the rotating shaft 13, and the relative movement direction XX of the first housing 11 and the second housing 12 is the relative rotation direction of the first housing 11 and the second housing 12.

[0039] In other embodiments, the second conductive structure 42 may also extend continuously along the relative movement direction XX of the first housing 11 and the second housing 12. When the first conductive structure 41 is in different working positions, the first conductive structure 41 is always in contact with the second conductive structure 42. It can be understood that in this embodiment, the second conductive structure 42 is a connecting and extending conductor structure. When the first conductive structure 41 moves between various working positions, the first conductive structure 41 remains in contact with the second conductive structure 42 and is in contact with it; when the first conductive structure 41 is in a de-energized position, the first conductive structure 41 is separated from the second conductive structure 42 and disconnected.

[0040] See also Figures 5 to 7As shown, in some embodiments, the triggering component 50 includes a first triggering structure 51 and a second triggering structure 52; the first triggering structure 51 is disposed in the first housing 11 and electrically connected to the electronic control component 20, and the first triggering structure 51 is used to send a position signal to the electronic control component 20 according to the position of the first conductive structure 41; the second triggering structure 52 is disposed in the second housing 12, and the second triggering structure 52 is used to cooperate with the first triggering structure 51 to detect the position of the first conductive structure 41.

[0041] It is understandable that when the relative movement of the first housing 11 and the second housing 12 causes a change in the relative positional relationship between the first conductive structure 41 and the second conductive structure 42, the relative positional relationship between the first trigger structure 51 and the second trigger structure 52 will also change synchronously. Through the cooperation of the second trigger structure 52 and the first trigger structure 51, the relative positional relationship between the first trigger structure 51 and the second trigger structure 52 can be detected, thereby detecting the position of the first conductive structure 41. Furthermore, the first trigger structure 51 can send a position signal to the electronic control component 20 according to the position of the first conductive structure 41, so that the electronic control component 20 can output the corresponding current according to the position of the first conductive structure 41.

[0042] like Figures 5 to 7 As shown, in some embodiments, multiple first trigger structures 51 are provided, and the multiple first trigger structures 51 are arranged at intervals along the relative movement direction XX of the first housing 11 and the second housing 12. When the first conductive structure 41 is in different working positions, the second trigger structure 52 contacts different first trigger structures 51 to detect the position of the first conductive structure 41 and send a position signal corresponding to the position of the first conductive structure 41 to the electronic control component 20.

[0043] It is understood that the number of first trigger structures 51 can be the same as the number of working positions and correspond one-to-one. When the first conductive structure 41 is in different working positions, the second trigger structure 52 will contact different first trigger structures 51, thereby enabling the trigger component 50 to send different position signals to the electronic control component 20, and the sent position signals correspond to the positions of the first conductive structures 41. After receiving the corresponding position signal, the electronic control component 20 can output the corresponding current through the output terminal. It should also be noted that when the first housing 11 and the second housing 12 are rotatably connected by the rotating shaft 13, the multiple first trigger structures 51 are arranged at intervals around the outer periphery of the rotating shaft 13.

[0044] In other embodiments, multiple second trigger structures 52 are provided, and the multiple second trigger structures 52 are arranged at intervals along the relative movement direction XX of the first housing 11 and the second housing 12. When the first conductive structure 41 is in different working positions, the first trigger structure 51 contacts different second trigger structures 52 to detect the position of the first conductive structure 41 and send a position signal corresponding to the position of the first conductive structure 41 to the electronic control component 20.

[0045] It is understood that the number of second trigger structures 52 can be the same as the number of working positions and correspond one-to-one. When the first conductive structure 41 is in different working positions, the first trigger structure 51 will contact different second trigger structures 52, thereby enabling the trigger component 50 to send different position signals to the electronic control component 20, and the sent position signals correspond to the positions of the first conductive structure 41. After receiving the corresponding position signal, the electronic control component 20 can output the corresponding current through the output terminal. It should also be noted that when the first housing 11 and the second housing 12 are rotatably connected by the rotating shaft 13, the multiple second trigger structures 52 are arranged at intervals around the outer periphery of the rotating shaft 13.

[0046] See also Figures 5 to 8 As shown, in some embodiments, the first trigger structure 51 includes a first contact 511 and a second contact 512 that are separately disposed; as Figure 8 As shown, the triggering component 50 also includes a signal input unit 53 and a signal detection unit 54. The signal input unit 53 is electrically connected to the first contact 511 and is used to output a detection signal to the first contact 511. The signal detection unit 54 is connected in series between the second contact 512 and the electronic control component 20.

[0047] Among them, such as Figure 2 and Figure 8 As shown, the second trigger structure 52 is a conductive structure, which can be formed of copper, copper alloy, aluminum, aluminum alloy, or other conductive materials. When the first conductive structure 41 is in the working position, both the first contact 511 and the second contact 512 are in contact with the second trigger structure 52 and are connected through the second trigger structure 52. This allows the first trigger structure 51 to transmit a detection signal to the signal detection unit 54. The signal detection unit 54 sends a position signal to the electronic control component 20 based on the received detection signal. It is understood that the signal input unit 53 can continuously output a detection signal to the first contact 511. When the first conductive structure 41 is in the de-energized position, the first contact 511 and the second contact 512 can be separated from the conductive structure, and at this time the first contact 511 and the second contact 512 are disconnected. When the first conductive structure 41 is in any working position, the first contact 511 and the second contact 512 are connected through the second trigger structure 52. At this time, the first trigger structure 51 and the electronic control component 20 form a connected signal detection circuit, so that the detection signal can be transmitted to the signal detection unit 54 through the first trigger structure 51. The signal detection unit 54 can send a corresponding position signal to the electronic control component 20 according to the received detection signal, and the transmitted position signal corresponds to the position of the first conductive structure 41, so that the electronic control component 20 can output the corresponding current from the output terminal according to the position signal.

[0048] It should also be noted that when multiple first trigger structures 51 are provided, if the first conductive structure 41 is in the first working position, the first contact 511 and the second contact 512 of one first trigger structure 51 are in contact with the second trigger structure 52; if the first conductive structure 41 is in the second working position, the first contact 511 and the second contact 512 of another first trigger structure 51 are in contact with the second trigger structure 52. Similarly, when multiple second trigger structures 52 are provided, if the first conductive structure 41 is in the first working position, the first contact 511 and the second contact 512 of the first trigger structure 51 are in contact with one second trigger structure 52; if the first conductive structure 41 is in the second working position, the first contact 511 and the second contact 512 of the first trigger structure 51 are in contact with another second trigger structure 52.

[0049] It should also be noted that, see Figures 8 to 10 As shown, taking the first trigger structure 51 as an example, if multiple trigger structures are configured, such as... Figure 8 As shown, when the first conductive structure 41 is in the first working position, the first contact 511 and the second contact 512 of the first trigger structure 51 can contact and conduct with the second trigger structure 52. At this time, the detection signal output by the signal input unit 53 is transmitted to the signal detection unit 54 through the first trigger structure 51. When the signal detection unit 54 receives the detection signal transmitted by the first trigger structure 51, it outputs a first position signal. The electronic control component 20 outputs a first current from the output terminal according to the first position signal, so that the charger is in the first charging mode.

[0050] like Figure 9As shown, when the first conductive structure 41 is in the second working position, the first contact 511 and the second contact 512 of the second first trigger structure 51 can contact and conduct with the second trigger structure 52. At this time, the detection signal output by the signal input unit 53 is transmitted to the signal detection unit 54 through the second trigger structure 52. When the signal detection unit 54 receives the detection signal transmitted by the second first trigger structure 51, it outputs a second position signal. The electronic control component 20 outputs a second current from the output terminal according to the second position signal, so that the charger is in the second charging mode.

[0051] like Figure 10 As shown, when the first conductive structure 41 is in the third working position, the first contact 511 and the second contact 512 of the third first trigger structure 51 can contact and conduct with the second trigger structure 52. At this time, the detection signal output by the signal input unit 53 is transmitted to the signal detection unit 54 through the third second trigger structure 52. When the signal detection unit 54 receives the detection signal transmitted by the third first trigger structure 51, it outputs a third position signal. The electronic control component 20 outputs a third current from the output terminal according to the second position signal, so that the charger is in the third charging mode.

[0052] Similarly, in other embodiments, when multiple second trigger structures 52 are provided, when the first conductive structure 41 is located in different working positions, the first contact 511 and the second contact 512 of the first trigger structure 51 contact and conduct with different second trigger structures 52. When the signal detection unit 54 receives the detection signal sent by different second trigger structures 52, it sends the corresponding position signal to the electronic control component 20, thereby causing the output terminal of the electronic control component 20 to output the corresponding current.

[0053] In some embodiments, the first trigger structure 51 and the second trigger structure 52 are both located inside the protective shell 10, so that the sparks that may be generated when the first trigger structure 51 and the second trigger structure 52 come into contact and separate are hidden inside the protective shell 10, thereby eliminating the discomfort caused to the user by the sparks generated by ignition.

[0054] In some embodiments, the first contact 511 and / or the second contact 512 are elastic contacts, such that the first contact 511 and / or the second contact 512 are elastic, thereby making the first contact 511 and the second contact 512 make closer contact when they come into contact.

[0055] like Figure 11As shown, in some embodiments, the signal input unit 53 includes a first resistor R1 and a second resistor R2; the first end of the first resistor R1 is electrically connected to the electronic control component 20 and is used to receive the detection signal output by the electronic control component 20, the detection signal being a voltage signal VSS; the first end of the second resistor R2 is electrically connected to the second end of the first resistor R1 and the first contact 511 at the first node T1, and the second end of the second resistor R2 is grounded.

[0056] It is understood that in this embodiment, the detection signal is the voltage signal VSS provided by the electronic control component 20, and the signal detection unit 54 is a voltage detector. When multiple first trigger structures 51 are provided, the signal detection unit 54 can send corresponding position signals to the electronic control component 20 according to the voltage signals VSS transmitted by different first trigger structures 51; when multiple second trigger structures 52 are provided, the signal detection unit 54 can send corresponding position signals to the electronic control component 20 according to the voltage signals VSS transmitted by different second trigger structures 52. It should also be noted that the first resistor R1 and the second resistor R2 can be integrated on the circuit board of the electronic control component 20.

[0057] In other embodiments, the detection signal can also be other signals, such as a current signal. In this case, the signal detection unit 54 is a current detector, capable of detecting the current at the first node T1. The detection signal can also be a pressure signal. In this case, the signal input unit 53 can be a pressure sensing element, capable of detecting the pressure between the first trigger structure 51 and the second trigger structure 52. The detection signal can also be a photoelectric signal. In this case, the signal input unit 53 can be a photoelectric sensing element, capable of detecting the light signal between the first trigger structure 51 and the second trigger structure 52. In this case, the signal detection unit 54 is a photoelectric detector.

[0058] like Figure 8 As shown, in some embodiments, when multiple first trigger structures 51 are provided, the signal detection unit 54 may include only one signal detector. In this case, resistors of different resistance values ​​can be connected in series between the second contact 512 of each first trigger structure 51 and the signal detection unit 54, so that when the detection signal is transmitted to the signal detection unit 54 through different first trigger structures 51, the voltage value of the detection signal detected by the signal detection unit 54 is different. Figure 11 As shown, when the signal detection unit 54 includes multiple signal detectors, the number of signal detectors is the same as the number of first trigger structures 51 and corresponds one-to-one. Different signal detectors can detect the detection signals transmitted by different first trigger structures 51.

[0059] In other embodiments, when multiple second trigger structures 52 are provided, each second trigger structure 52 can be designed with a different resistance value, so that when the detection signal is transmitted to the signal detection unit 54 through different second trigger structures 52, the voltage value of the detection signal detected by the signal detection unit 54 is different.

[0060] See also Figure 11 As shown, in some embodiments, the triggering component 50 may further include a filtering unit 55. The filtering unit 55 includes a third resistor R3 and a capacitor C1. The first end of the third resistor R3 is electrically connected to the signal detection unit 54, and the second end of the third resistor R3 is electrically connected to the first end of the capacitor C1 and the electronic control component 20 at the second node T2. The second end of the capacitor C1 is grounded. The filtering unit 55, composed of the third resistor R3 and the capacitor C1, can filter out noise signals between the signal detection unit 54 and the electronic control component 20, making the detection signal received by the electronic control component 20 more accurate.

[0061] It should also be noted that when there are multiple first trigger structures 51 and signal detectors, there can be multiple filtering units 55. The number of filtering units 55 is the same as the number of signal detectors and they correspond one-to-one. One filtering unit 55 is connected to one signal detector.

[0062] In some embodiments, the charger may further include a positioning reminder structure, which may include a slot and a flexible protrusion. One of the slot and the flexible protrusion is disposed in the first housing 11, and the other of the slot and the flexible protrusion is disposed in the second housing 12. There may be multiple slots. Taking multiple slots as an example, the multiple slots are arranged at intervals along the relative movement direction XX of the first housing 11 and the second housing 12. When the first conductive structure 41 is in different working positions, the flexible protrusion engages with different slots to remind the user that the first conductive structure 41 has been moved into position.

[0063] Of course, in other embodiments, some status indicator lights or display screens can be provided on the protective shell 10 to indicate the position of the first conductive structure 41. For example, when different status indicator lights are displayed, it indicates that the first conductive structure 41 is located in the corresponding working position.

[0064] See also Figure 2 and Figure 4 As shown, in some embodiments, the first housing 11 encloses to form a first cavity 111, and a first through hole 112 communicating with the first cavity 111 is provided on the side of the first housing 11 facing the second housing 12 (e.g., Figure 6The electronic control component 20 is installed inside the first cavity 111, and the first conductive structure 41 and the first trigger structure 51 are installed in the first through hole 112 and exposed to the outside of the first housing 11 through the first through hole 112. The second housing 12 encloses to form the second cavity 121, and a second through hole 122 communicating with the second cavity 121 is provided on the side of the second housing 12 facing the first housing 11 (e.g., Figure 5 The second conductive structure 42 is mounted on the first via 112 and exposed to the outside of the second housing 12 through the second via 122.

[0065] In some embodiments, the rotating shaft 13 can be fixed to the side of the first housing 11 facing the second housing 12. The side of the second housing 12 facing the first housing 11 can be provided with a bushing 14. The rotating shaft 13 is inserted into the bushing 14. A bearing 15 can be fitted on the rotating shaft 13. The inner ring of the bearing 15 is connected to the outer circumference of the rotating shaft 13, and the outer ring of the bearing 15 is connected to the inner wall of the bushing 14. The rotating shaft 13 is rotatably connected to the bushing 14 through the bearing 15, thereby making the first housing 11 and the second housing 12 rotatably connected. The bearing 15 can reduce the friction when the rotating shaft 13 and the bushing 14 rotate relative to each other, thereby making the rotation faster and smoother. Of course, according to actual needs, the bushing 14 can also be omitted, and the outer circumferential surface of the rotating shaft 13 can directly contact the inner wall of the bushing 14.

[0066] In some embodiments, the charger further includes an annular groove 16 and an annular stop 17. The annular groove 16 is disposed on one of the first housing 11 and the second housing 12, and the annular groove 16 extends along the outer periphery of the rotating shaft 13, and the axis of the annular groove 16 coincides with the axis of the rotating shaft 13. The annular stop 17 is disposed on the other of the first housing 11 and the second housing 12, and the annular groove 16 extends along the outer periphery of the rotating shaft 13. The annular stop 17 is inserted into the annular groove 16 and can slide along the annular groove 16. The first conductive structure 41 and the second conductive structure 42 are both located inside the annular stop 17.

[0067] It is understood that the annular stop 17, the first housing 11, and the second housing 12 can together enclose a relatively sealed space. The first conductive structure 41 and the second conductive structure 42 are both located within this sealed space. The sparks generated when the first conductive structure 41 and the second conductive structure 42 come into contact can be isolated by the annular stop 17, preventing the user from sensing the sparks generated when striking the spark through the gap between the first housing 11 and the second housing 12. In addition, the annular stop 17, the annular groove 16, and the rotating shaft 13 are all coaxially arranged (i.e., their axes coincide), allowing the annular stop 17 to rotate around the same axis as the first housing 11 and the second housing 12, thereby preventing the annular stop 17 from obstructing the relative rotation of the first housing 11 and the second housing 12.

[0068] Specifically, the annular stop 17 can be fixed to the side of the first housing 11 facing the second housing 12, in which case the annular groove 16 is provided on the side of the second housing 12 facing the first housing 11; of course, the annular stop 17 can also be fixed to the side of the second housing 12 facing the first housing 11, in which case the annular groove 16 is provided on the side of the first housing 11 facing the second housing 12. The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
