[0030] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0031] With the improvement of living standards, cars have become a popular means of transportation. Driving or riding in a car has become a travel trend. At the same time, with the diversification of electronic product functions, the energy consumption of electronic products carried by users has also increased. To meet users' needs for charging electronic products anytime, anywhere, car chargers have emerged. Car chargers are widely welcomed for their small size, light weight, and portability. However, car chargers have limited functionality and cannot meet diverse needs.

[0032] To address the above technical problems, this utility model provides a vehicle charger. Figure 1 A schematic diagram of the structure of the vehicle charger provided by this utility model is shown below. Figure 1 As shown, the vehicle charger 100 may include a status detection module 101, a data acquisition module 102, a control module 103, and a wireless communication module 104. The status detection module 101 is pluggably and electrically connected to the vehicle's status output module to detect whether the vehicle is in a locked state. The control module 103 is electrically connected to the status detection module 101 and the data acquisition module 102, and is used to receive the locked state and control the data acquisition module 102 to acquire audio data from inside the vehicle's cabin. The data acquisition module 102 is used to send the audio data to the control module 103. The control module 103 is also electrically connected to the wireless communication module 104, and is used to receive and send audio data to the wireless communication module 104. The wireless communication module 104 is used to receive and send audio data to a first device.

[0033] In one embodiment, the on-board charger 100 may further include a module for transmitting electrical energy output from the vehicle to power-consuming devices.

[0034] In one implementation, the vehicle may include an automobile powered by any of fuel, natural gas, or electricity.

[0035] In one implementation, the status output module may include a hardware module integrated in the vehicle that can output whether the vehicle is currently locked.

[0036] In one implementation, the locked state may include the vehicle being stopped and the vehicle doors being locked.

[0037] In one embodiment, the protruding component corresponding to the input end of the state detection module 101 can be pluggably connected to the recessed component corresponding to the output end of the state detection module.

[0038] In one embodiment, when the status detection module 101 is electrically connected to the status output module, it can continuously detect whether the vehicle is in a locked state, and when the vehicle is detected to be in a locked state, it sends the locked state to the control module 103.

[0039] In one embodiment, the control module 103 may be at least one of the following: Application-Specific Integrated Circuit (ASIC), Digital Signal Processor (DSP), Digital Signal Processing Device (DSPD), Programmable Logic Device (PLD), Field Programmable Gate Array (FPGA), Central Processing Unit (CPU), Controller, Microcontroller Unit (MCU), and Microprocessor.

[0040] In one implementation, after receiving the locked state, the control module 103 can generate a data acquisition command and send the data acquisition command to the data acquisition module 102.

[0041] In one implementation, after receiving a data acquisition command, the data acquisition module 102 can continuously or periodically acquire audio data inside the carriage.

[0042] In one implementation, if there are people and / or pets remaining inside the carriage, the audio data may include sounds made by the people or pets remaining inside the carriage.

[0043] In one embodiment, the wireless communication module 104 can send audio data to the first device via any type of mobile communication connection; for example, the wireless communication module 104 can send audio data to the first device via email, social media data transmission, and telephone calls.

[0044] In one embodiment, the first device may include a server device or a terminal device. For example, after receiving audio data, the server device may send the audio data to a mobile phone or smart wearable device associated with the driver of the vehicle to alert the driver to the presence of people or pets inside the vehicle. For example, if the terminal device includes a smartphone or smart wearable device associated with the driver of the vehicle, the wireless communication module may directly send audio data to the smartphone or smart wearable device.

[0045] In practice, it is not uncommon for children and / or pets to be left inside a vehicle after the driver has left and locked the car. If the vehicle is in a harsh environment such as high or low temperature, the safety of the children or pets left inside will inevitably be threatened.

[0046] As can be seen from the above, the vehicle charger provided by this utility model has a status detection module that can be plugged into and electrically connected to the vehicle's status output module to detect whether the vehicle is in a locked state. Thus, the status detection module improves the flexibility of the electrical connection between the vehicle charger and the vehicle, and enables flexible detection of whether the vehicle is in a locked state. Furthermore, the control module receives the locked status information and controls the data acquisition module to collect audio data from inside the vehicle's cabin, thereby achieving precise control over whether the data acquisition module collects audio data. This reduces the power consumption of the data acquisition module continuously collecting audio data and minimizes the impact on audio quality. Data redundancy; simultaneously, after the data acquisition module sends audio data to the control module, the control module sends audio data to the wireless communication module, so that the wireless communication module can send audio data to the first device. In this way, audio data inside the vehicle can be sent to the first device in a timely manner when the vehicle is locked. If the audio data is related to people and / or pets left inside the vehicle, it can reduce the probability of the health or safety of people and / or pets left inside the vehicle being threatened. It can also improve the functionality of the on-board charger and at least meet the needs of ensuring the health and safety of people and / or pets inside the vehicle when the vehicle is locked.

[0047] Figure 2 Another structural schematic diagram of the vehicle charger provided in this embodiment of the utility model is shown below. Figure 2 As shown, in the vehicle charger 100 provided in this embodiment of the present utility model, the status output module includes a cigarette lighter assembly; the status detection module 101 includes a power detection assembly 1011, which is pluggably electrically connected to the cigarette lighter assembly and detects the power amplitude of the power output by the cigarette lighter assembly.

[0048] Among them, the amount of electrical energy output by the cigarette lighter assembly when the vehicle is in an unlocked state is greater than the amount of electrical energy output when the vehicle is in a locked state.

[0049] In one embodiment, the cigarette lighter assembly may include a cigarette lighter; for example, an on-board charger may transmit electrical energy output from the cigarette lighter to electronic devices such as mobile phones.

[0050] In one implementation, taking a new energy vehicle as an example, when the new energy vehicle is started or in an unlocked state, the voltage amplitude of the electrical energy output by its cigarette lighter component is between 13 and 15V. However, after it switches to the locked state, the voltage amplitude of the electrical energy output by the cigarette lighter component drops to 5V. Therefore, the power detection component 1011 can determine whether the new energy vehicle is in a locked state by detecting the amplitude of the electrical energy output by the cigarette lighter component.

[0051] In one embodiment, when the power detection component 1011 detects a decrease in the amplitude of the power output of the cigarette lighter component, it can generate and send a lock state to the control module 103 to trigger the control module 103 to control the audio acquisition module to acquire audio data, process the audio data into an electrical signal, and then send the audio data in the form of an electrical signal to the control module 103.

[0052] As described above, the vehicle charger provided by this utility model includes a status output module comprising a cigarette lighter assembly and a status detection module comprising a power detection component. The latter is pluggably connected to the cigarette lighter assembly and detects the amplitude of the power output by the cigarette lighter assembly. When the vehicle is unlocked, the amplitude of the power output by the cigarette lighter assembly is less than when the vehicle is locked. Thus, by utilizing the difference in the amplitude of the power output by the cigarette lighter assembly when the vehicle is locked and unlocked, the power detection component can easily, quickly, and flexibly detect fluctuations in the amplitude of the power output by the cigarette lighter assembly, thereby providing data support for determining whether the vehicle is locked.

[0053] Based on the foregoing embodiments, in the vehicle charger 100 provided by this utility model, the data acquisition module includes a first identification component 1021, which is used to process audio data into a first identification result and send the first identification result to a control module 103; the control module 103 is used to receive the first identification result and send warning data associated with the first identification result to a wireless communication module 104; the wireless communication module 104 is used to send warning data to a first device.

[0054] The first identification result includes at least data on people and / or pets remaining inside the carriage; the warning data includes at least information on people and / or pets remaining inside the carriage.

[0055] In one implementation, after the data acquisition module 102 sends the first identification result to the control module 103, the control module 103 can process the first identification result into warning data.

[0056] In one implementation, the alert data may be presented in at least one of text, voice, image, and animation.

[0057] In one implementation, the data content included in the warning data can be preset or flexibly generated by the control module 103 based on the audio data.

[0058] In one embodiment, the first recognition component 1021 may include a neural network model capable of vectorization processing of audio data, feature extraction, and recognition.

[0059] In one embodiment, the first identification component 1021 may send the first identification result to the control module 103 if it determines that the first identification result includes data that people and / or pets are left inside the carriage.

[0060] As described above, the vehicle charger provided by this utility model includes a data acquisition module comprising a first identification component, used to process audio data into a first identification result and send the first identification result to a control module.

The first identification result includes at least data indicating that people and / or pets are remaining inside the vehicle compartment, and the warning data includes at least information indicating that people and / or pets are remaining inside the vehicle compartment. Thus, the first identification component enriches the functionality of the data acquisition module and reduces the computational load on the control module for audio data processing. Furthermore, by associating the warning data with the first identification result, the accuracy of the warning data is improved. Simultaneously, by sending the warning data to a first device, precise synchronization of the presence of people and / or pets inside the vehicle compartment between the vehicle and the first device can be achieved, further enriching the data transmission capabilities of the vehicle charger.

[0061] Based on the foregoing embodiments, in the vehicle charger provided by this utility model, the control module 103 includes a second identification component 1031, which is used to process audio data into a second identification result and send warning data associated with the second identification result to the wireless communication module; the wireless communication module is used to send warning data to the first device.

[0062] The second identification result includes at least data on people and / or pets remaining inside the carriage; the warning data includes at least information on people and / or pets remaining inside the carriage.

[0063] In one embodiment, the second recognition component 1031 may include a neural network model capable of vectorization processing of audio data, feature extraction, and recognition.

[0064] In one implementation, the control module 103 may generate warning data based on the second identification result if it is determined that the second identification result includes data showing that at least a person and / or a pet is remaining inside the carriage.

[0065] As can be seen from the above, in the vehicle charger provided by this utility model, the control module includes a second identification component, which processes audio data into a second identification result and sends warning data associated with the second identification result, including at least the presence of people and / or pets inside the vehicle compartment, to the wireless communication module. The wireless communication module is used to send the warning data to a first device. Thus, through the second identification component, real-time and accurate identification of audio data is achieved, and the correlation between the warning data and the second identification result is improved, thereby increasing the accuracy of the warning data. Simultaneously, by sending the warning data to the first device, accurate synchronization of the presence of people and / or pets inside the vehicle compartment between the vehicle and the first device can be achieved, and the data transmission function of the vehicle charger can be enriched.

[0066] Based on the foregoing embodiments, the vehicle charger 100 provided by this utility model further includes an input module 105 for receiving warning data input by the user.

[0067] In one embodiment, the input module 105 may have at least one of the following functions: voice input, gesture input, touch input, and key input.

[0068] In one implementation, the alert data may be generated in advance by the user through input module 105, which can be edited or added by the user.

[0069] In one implementation, the input module can be electrically connected to the control module so that the control module can acquire and save the warning data.

[0070] In one embodiment, after receiving audio data, a first recognition result, or generating a second recognition result, the control module 103 can directly acquire and send warning data to the wireless communication module 104.

[0071] As can be seen from the above, the vehicle charger provided by this utility model also includes an input module for receiving warning data input by the user. Thus, through the above method, the controllability, flexibility, and personalization of the warning data can be pre-set, thereby enabling the warning data to meet the user's warning needs; furthermore, because the warning data is pre-set, the efficiency of the control module sending warning data to the wireless communication module can be improved.

[0072] Based on the foregoing embodiments, the vehicle charger 100 provided by this utility model further includes an input module 105 for receiving a device communication identifier associated with the first device input by the user.

[0074] In one implementation, the device communication identifier may include a mobile phone number written in the Subscriber Identity Module (SIM) set in the first device.

[0075] In one implementation, the input module can be electrically connected to the control module so that the control module can obtain and store the device communication identifier.

[0076] In one embodiment, after receiving audio data, a first identification result, or generating a second identification result, the control module 103 can directly obtain the device communication identifier and generate warning data. Then, it sends the device communication identifier and the warning data to the wireless communication module 104 so that the wireless communication module can send the warning data to the first device based on the device communication identifier.

[0077] As can be seen from the above, the vehicle charger provided by this utility model also includes an input module for receiving a device communication identifier associated with the first device input by the user. This device communication identifier is used by the wireless communication module to send warning data to the first device. Thus, by having the user pre-set the aforementioned device communication identifier, the stability of the wireless communication module sending warning data to the first device can be improved, thereby reducing the risk of warning data failing to be sent to the first device.

[0078] Based on the foregoing embodiments, in the vehicle charger 100 provided by this utility model, the wireless communication module 104 is also used to establish a communication connection with the second device and receive warning data sent by the second device through the communication connection.

[0079] In one implementation, the second device may be the same as or different from the first device.

[0080] In one implementation, the second device can be the host computer of the vehicle charger.

[0081] In one implementation, the vehicle charger receives warning data sent by the second device, which can be an operation performed before the vehicle charger is used for the first time, or it can be performed at any time during the use of the vehicle charger.

[0082] As can be seen from the above, the vehicle charger provided by this utility model also includes a wireless communication module for establishing a communication connection with a second device and receiving warning data sent by the second device through the communication connection.

[0096] Figure 3 Another structural schematic diagram of the vehicle charger provided by this utility model is shown below. Figure 3 As shown, the vehicle charger 100 may include a protruding component 301, a microphone module 302, a communication component 303, a housing 304, a universal serial bus (USB) interface 305, and a charging cable 306. The protruding component 301 may be the power detection component in the aforementioned embodiments, the microphone module 302 may be the data acquisition module in the aforementioned embodiments, and the communication component 303, which includes a SIM card, may be the wireless communication module in the aforementioned embodiments. Data and / or power transmission between the vehicle charger and other devices can be achieved through the USB interface 305 and the charging cable 306. Thus, while synchronizing audio data and warning data between the vehicle and the first device, the vehicle charger can also simultaneously function as a vehicle charging converter.

[0097] Figure 4 This is a schematic diagram of the connection between the vehicle charger and the cigarette lighter provided by this utility model, as shown below. Figure 4As shown, when the car charger is electrically connected to the cigarette lighter 401, the cigarette lighter 401 provides power to the DC-DC module and the low dropout regulator (LDO) through a fuse. The LDO provides stable power to the microphone module, MCU, and SIM module, while the DC-DC module provides power to the USB interface and retractable cable. At the same time, the cigarette lighter 401 can also directly provide power to the MCU.

[0098] The SIM module can be part of a wireless communication module; the retractable cable can be the charging cable in the aforementioned embodiment.

[0099] The above structure enables the vehicle's cigarette lighter to provide stable power to the various modules in the on-board charger, thereby improving the stability of the on-board charger's audio data acquisition and warning data transmission.

[0100] Figure 5 The warning data sending process provided by this utility model, such as Figure 5 As shown, the warning data sending process 500 can be implemented through the cooperation of the following modules:

[0101] When the cigarette lighter is electrically connected to the vehicle charger, the LDO can provide power to the MCU and microphone module. In this case, the MCU module can also function as the control module and status detection module in the aforementioned embodiments. If it detects that the output power of the cigarette lighter has dropped to about 5V, it controls the microphone module to collect audio data. After the microphone module collects the audio data, it sends it to the MCU module for the MCU module to identify the audio data. If it determines that the audio data indicates that there are people and / or pets left in the vehicle, it instructs the SIM module to transmit warning data and phone number to the transmitting module, so that the transmitting module can send the warning data and / or audio data to the first device associated with the driver based on the phone number. The wireless communication module in the aforementioned embodiments may include the SIM module and the transmitting module, and the phone number can be the device communication identifier.

[0102] Through the above process, the vehicle charger can promptly detect the presence of people and / or pets inside the vehicle and accurately and stably transmit warning data.

[0103] Figure 6 This is a schematic diagram illustrating the process of saving warning data and phone numbers provided by this utility model. (For example...) Figure 6 As shown, the alert data and phone number saving process 600 can be implemented in the following ways:

[0104] When the car charger is electrically connected to the vehicle's cigarette lighter, if the cigarette lighter's output voltage is greater than 5V, the microphone module can stop collecting data, while the SIM module can be in operation. At this time, pressing and holding the car charger's switch can trigger the car charger to connect to a second device, including the user's mobile phone, via Bluetooth. For example, the user can edit warning data, including SMS or call content, and the phone number associated with the first device, through an application set in the second device, and write the warning data and phone number into the SIM module via Bluetooth connection.

[0105] When the SIM module is written with warning data and a phone number, and the vehicle is switched to the locked state, if the MCU detects that the output voltage of the cigarette lighter has dropped to 5V, the MCU can send a data acquisition command, including a high level or a low level, to the microphone module through the first general-purpose input / output (GPIO) to control the microphone module to collect audio data inside the vehicle and send the audio data to the MCU. At this time, the MCU can send an instruction to the SIM module through the second GPIO to trigger the SIM module to send warning data to the first device.

[0106] It should be noted that in this invention, the SIM module can function as both a storage module and a wireless communication module.

[0107] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
