[0030] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0031] It should be pointed out that the embodiments of the present invention and the technical features therein may be combined with each other without conflict.

[0032] Figure 1 and Figure 2FIG. 1 is a partial structural diagram of a vehicle-mounted charging device according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the vehicle-mounted charging device 10 may include: an electrical connector 11, a charging circuit 12, a microcontroller module 13, a processor 14 and a voice playback module 15, wherein:

[0033] The electrical connector 11 is connected to the charging circuit 12, and when an external electrical connection device is connected, an electrical connection between the charging circuit 12 and the external electrical connection device is established;

[0034] The microcontroller module 13 is used to monitor the charging status of the charging circuit in real time, generate a control signal indicating the charging status, and send the control signal to the processor 14;

[0035] The processor 14 is used to control the voice playing module 15 to play a prompt tone indicating the charging status according to the control signal.

[0036] It is worth noting that the vehicle-mounted charging device provided in the embodiment of the present invention can be a device for charging new energy vehicles, or it can be a device installed in the cabin for passengers to use to charge electronic devices (such as mobile phones, speakers, smart watches, etc.).

[0037] Wherein, in case that the on-board charging device is a device for charging new energy vehicles, the electrical connector 11 can be as follows: Figure 2 As shown, it is a charging port connected to the charging gun of an external charging pile. Accordingly, the external electrical connection device is the charging gun of the charging pile. It is worth noting that Figure 2 The charging port shown is only an example, and the charging port can also be a magnetic charging structure.

[0038] In addition, in the case where the vehicle-mounted charging device is a device for charging electronic devices (such as mobile phones, speakers, smart watches, etc.), the above-mentioned electrical connector 11 can be a USB interface connected to one end of an external charging cable, a magnetic charging structure, etc. Correspondingly, the above-mentioned external electrical connection device is an electronic device such as a mobile phone, speaker, smart watch, etc.

[0039] It can be understood that in the case where the on-board charging device is a device for charging new energy vehicles, the above-mentioned charging circuit 12 connects the electrical connector 11 and the rechargeable battery of the new energy vehicle, so as to charge the battery of the new energy vehicle through the charging gun connected to the electrical connector 11 on the charging pile, the electrical connector 11 and the charging circuit 12.

[0040] In addition, in the case where the vehicle-mounted charging device is a device for charging electronic devices (such as mobile phones, speakers, smart watches, etc.), the above-mentioned charging circuit 12 connects the electrical connector 11 and a battery that provides electrical energy, so as to charge the electronic device connected to the electrical connector 11 through the battery, the charging circuit 12 and the electrical connector 11.

[0041] Among them, the micro-control module 13 can be arranged on the above-mentioned charging circuit 12 to monitor the voltage, current, charging power of the charging circuit 12 in real time (such as the charging power of the rechargeable battery of the new energy vehicle when the on-board charging device is a device for charging new energy vehicles; the charging power of the electronic device when the on-board charging device is a device for charging electronic devices, etc.). It is worth noting that when the on-board charging device is a device for charging new energy vehicles, the micro-control module 13 can obtain the charging power of the rechargeable battery from the on-board battery management system, or obtain the charging power of the rechargeable battery from the charging pile, etc. When the on-board charging device is a device for charging electronic devices, the micro-control module 13 can obtain the charging power of the electronic device from the on-board central control system, or obtain its charging power from the electronic device.

[0042] It is worth noting that the electrical connector, charging circuit, microcontroller module, processor and voice playback module are generally integrated into the vehicle-mounted charging device.

[0043] For the vehicle-mounted charging device provided in the embodiment of the present invention, an electrical connection is established between the charging circuit and an external electrical connection device through an electrical connector to realize the basic charging function of the vehicle-mounted charging device, and the charging status of the charging circuit is monitored in real time through the microcontroller module to generate a control signal indicating the charging status. The processor controls the voice playback module to play a prompt sound indicating the charging status according to the control signal. That is, through the cooperation of the microcontroller module and the processor, the voice playback module can play a prompt sound according to the charging status, so that the user can directly know the charging status according to the prompt sound without the user having to specifically observe the charging status, thereby improving the user experience.

[0044] Understandably, if the on-board charging device is a device for charging new energy vehicles, the user can obtain the charging status of the new energy vehicle through the prompt sound played by the voice playback module outside the cockpit. In addition, if the on-board charging device is a device for charging electronic devices (such as mobile phones, speakers, smart watches, etc.), the occupants or drivers can directly learn the charging status of the electronic devices through the prompt sound of the voice playback module. The occupants or drivers do not need to check the electronic devices, which ensures the driver's driving safety and improves the occupants' experience of charging electronic devices.

[0045] Furthermore, the processor 14 may be further configured to control the voice playback module 15 to play background music that matches the charging status, and adjust the volume of the background music according to the charging status.

[0046] The background music matching the charging status may be configured by the user according to personal preference, or may be determined by a mapping relationship between the charging status and the background music configured in the processor 14 .

[0047] In addition, each charging state is configured with a corresponding background music set (the background music set includes multiple background music matching the same charging state). For the charging state, the processor 14 is further used to control the voice playback module 15 to play the background music matching the charging state. Specifically, the processor 14 randomly selects a background music from the background music set matching the charging state and provides it to the voice playback module 15, and the voice playback module 15 plays the background music provided by the processor 14.

[0048] By controlling the voice playing module 15 to play background music that matches the charging status and adjusting the volume of the background music, the user can accurately and timely know the charging status of the vehicle-mounted charging device based on the background music and the volume.

[0049] Exemplarily, background music A is configured for a charging power of 80% to 90%, and background music B is configured for a charging power of 70% to 80%. When the charging power of the electrical connection device connected to the electrical connection member 11 is within the range of 80% to 90%, the processor 14 controls the voice playback module 15 to play background music A, and within the range of 80% to 90%, as the charging power increases, the volume of the voice playback module 15 gradually increases. When the charging power of the electrical connection device connected to the electrical connection member 11 is within the range of 70% to 80%, the processor 14 controls the voice playback module 15 to play background music B, and within the range of 70% to 80%, as the charging power increases, the volume of the voice playback module 15 gradually increases. Generally speaking, the volume of the voice playback module 15 within the charging power of 70% to 80% is lower than the volume of the voice playback module 15 within the charging power of 80% to 90%.

[0050] In addition, the microcontroller module 13 is further used to monitor the current and / or voltage of the charging circuit and generate a control signal indicating the current and / or voltage;

[0051] The processor 14 is further used to analyze whether the charging is abnormal based on the current and / or voltage indicated by the control signal. When the analysis result indicates that the charging is abnormal, the voice playback module 15 is controlled to play a prompt sound indicating the charging abnormality; when the analysis result indicates that the charging is normal, the voice playback module 15 is controlled to play background music matching the current and / or voltage.

[0052] A mapping relationship between the control signal and the current and / or voltage is configured between the processor 14 and the microcontroller module 13. Therefore, the microcontroller module 13 can determine the control signal corresponding to the current and / or voltage based on the mapping relationship. Accordingly, the processor 14 can determine the current and / or voltage corresponding to the control signal based on the mapping relationship. The current and / or voltage are transmitted between the processor 14 and the microcontroller module 13 through the control signal, so that the processor 14 and the microcontroller module 13 can respectively record the current and / or voltage in their own formats, without the need for the processor 14 and the microcontroller module 13 to unify the data format. The timeliness of the synchronization of the current and / or voltage between the processor 14 and the microcontroller module 13 can be effectively guaranteed through the control signal transmission.

[0053] It is understandable that the micro-control module 13 may monitor only the current of the charging circuit 12 , or may monitor only the voltage of the charging circuit 12 , or may monitor both the current and the voltage of the charging circuit 12 simultaneously.

[0054] The processor 14 analyzes whether the charging is abnormal by comparing the current indicated by the control signal with the rated current of the on-board charging device. If the current indicated by the control signal does not reach the rated current or is lower than the rated current, the charging is determined to be abnormal; otherwise, the charging is determined to be normal. The processor 14 may also compare the voltage indicated by the control signal with the rated voltage of the on-board charging device. If the voltage indicated by the control signal does not reach the rated voltage or is lower than the rated voltage, the charging is determined to be abnormal; otherwise, the charging is determined to be normal. The processor 14 may also compare the current and voltage indicated by the control signal with the rated current and rated voltage of the on-board charging device respectively. Only when the current and voltage reach the rated current and rated voltage respectively, the charging is determined to be normal.

[0055] By playing a prompt tone indicating abnormal charging (such as a prompt tone directly indicating abnormal charging or an alarm sound or a harsh background music) through the voice playback module 15, the user can promptly discover the abnormal charging and check the cause of the abnormal charging. In addition, when charging is normal, the voice playback module plays background music that matches the current and / or voltage to provide the user with a comfortable background music environment, so that the user can be in a good mood and improve the user's charging experience.

[0056] In addition, the processor 14 can be further used to control the voice playback module to play the charging status when the charging status satisfies the preset status condition. The preset status condition can be a user-defined charging power threshold or charging consumption amount. For example, the user sets the charging power threshold of the rechargeable battery of the new energy vehicle to 80%. After the power of the rechargeable battery of the vehicle reaches 80%, the voice playback module is controlled to play the charging status to remind the user to end charging. This can meet the needs of different users and remind users in time.

[0057] Furthermore, the vehicle charging device may also include: an interaction module 16, wherein the interaction module 16 is used to receive interaction information input from the outside, and the interaction information indicates playing background music; the processor 14 is triggered in response to the interaction information, and further controls the voice playback module 15 to play background music matching the interaction information.

[0058] Among them, the interaction module can be a communication module for the vehicle system and the processor 14 to realize communication. Accordingly, the interaction information can be input by the user through the vehicle system through the communication between the vehicle system and the processor 14. The interaction module can also be a voice receiving module. Accordingly, the interaction information is the user's voice command. In addition, the interaction module can also be a button or touch screen component provided to the user. That is, the processor 14 can also control the voice playback module 15 to play background music matching the interaction information according to the user's demand for background music through the interaction information. That is to say, the voice playback module in the vehicle charging device provided in the embodiment of the present invention plays background music according to the charging status. Regardless of whether the vehicle charging device is in the charging stage, it can also play the background music that the user wants to listen to through the interaction module according to the user's demand, so as to meet the user's demand and further improve the user experience.

[0059] Furthermore, the interaction module 16 is further used to receive voice commands input from the outside and send the voice commands to the processor 14;

[0060] The processor 14 is further configured to recognize the voice command and, based on the recognition result, execute an operation matching the voice command.

[0061] In addition, in addition to meeting user needs and enabling the processor 14 to cooperate with the voice playback module 15 to play background music, the above-mentioned interactive module 16 can also meet the user's needs for more voice control of the vehicle charging device, such as stopping charging, continuing charging, and broadcasting the current charging status.

[0062] The processor 14 is further configured to generate and send a stop charging signal to the microcontroller module 13 when the result of the identification indicates that charging should be stopped; and to generate and send a charging signal to the microcontroller module 13 when the result of the identification indicates that charging should be switched from the stop charging state to the continue charging state;

[0063] The microcontroller module 13 is used to cut off the charging circuit according to the stop charging signal and to turn on the charging circuit according to the charging signal.

[0064] Through the above process, the charging process of the on-board charging device can be controlled by voice to further enhance the user experience.

[0065] In addition, the processor 14 can also be further used to adjust the background music played by the voice playback module 15 or adjust the volume of the background music played according to the change of current and / or voltage. By adjusting the background music played by the voice playback module 15 or adjusting the volume of the background music played, the user can pay attention to the change of current and / or voltage, so as to effectively reduce the risk of damage to the charging circuit, rechargeable battery or electronic equipment caused by long-term excessive current and / or voltage.

[0066] In view of the situation that the vehicle-mounted charging device includes an interactive module 16, and the user can control the voice playback module to play the background music that he wants to listen to through the interactive module 16, in order to avoid the influence of the charging state on the background music, the processor 14 further interrupts the connection with the micro-control module 13 in response to the interactive information trigger; and re-establishes the connection with the micro-control module 13 in response to receiving the switching instruction indicating the exit control of the interactive information. By interrupting the connection with the micro-control module 13, the charging state can no longer affect the background music played by the voice playback module, meeting the user's need to independently use the voice playback module to play the background music he wants.

[0067] Furthermore, if Figure 3 As shown, an embodiment of the present invention provides a voice playback device 30. The voice playback device 30 can be connected to the vehicle charging device signal. Specifically, the voice playback device 30 includes: a processor 14 and a voice playback module 15, wherein:

[0068] The processor 14 is used to receive a control signal indicating the charging status sent by the micro-control module when being signal-connected to the micro-control module of the vehicle-mounted charging device; and control the voice playing module to play a prompt tone indicating the charging status according to the control signal.

[0069] Among them, the on-board charging device can be a charging port for charging rechargeable batteries of existing vehicles, or it can be a charging port set in the cockpit for charging electronic devices. A communication module can be integrated on the charging port, and the processor 14 communicates with the microcontroller module of the on-board charging device through the communication module.

[0070] It is worth noting that the micro-control module is also a module that already exists in the vehicle-mounted charging device, that is, the voice playback device 30 provided in the embodiment of the present invention is suitable for a vehicle-mounted charging device having a micro-control module.

[0071] By communicating between the voice playing device 30 and the vehicle-mounted charging device having a microcontroller module, various functions of the above-mentioned vehicle-mounted charging device can be realized. According to the charging status, a prompt tone matching the charging status is played to enhance the user experience.

[0072] Furthermore, an embodiment of the present invention also provides a computer-readable medium on which a computer program for implementing various functions of the processor is stored.

[0073] According to the vehicle-mounted charging device of the embodiment of the present invention, an electrical connection is established between the charging circuit and an external electrical connection device through an electrical connector to realize the basic charging function of the vehicle-mounted charging device, and the charging status of the charging circuit is monitored in real time through the micro-control module to generate a control signal indicating the charging status. The processor controls the voice playback module to play a prompt sound indicating the charging status according to the control signal. That is, through the cooperation of the micro-control module and the processor, the voice playback module can play the prompt sound according to the charging status, so that the user can directly know the charging status according to the prompt sound without the user specifically observing the charging status, thereby improving the user experience.

[0074] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may occur depending on design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
