[0002] With the continuous progress and expansion of the new energy vehicle industry, the functional design of the whole vehicle is also constantly moving towards greater convenience and comfort. When using fuel vehicles or new energy vehicles in daily life, there are often problems such as not being able to find the remote key or wasting time searching for the remote key. Even when using a mobile APP to control the vehicle, the remote key is still needed when the network is poor, the mobile phone is lost or forgotten, the vehicle is under long-term maintenance, the vehicle is left at a car wash, or the vehicle manufacturer is testing the vehicle.

[0003] However, it is challenging to achieve the function of retrieving the remote key without increasing its size or reducing costs. The operating voltage of voice chips is generally no lower than 3V, which is the highest operating voltage for car remote keys. Therefore, the operating voltage of voice chips limits their use in remote keys and urgently needs to be addressed. Utility Model Content

[0004] This application provides a remote key and vehicle with voice retrieval capability, which solves the problem that keys cannot integrate voice retrieval function due to size and voltage limitations in related technologies, thereby improving the user's convenience.

[0005] The first aspect of this application provides a voice-activated remote key, comprising: a boost circuit, a voice chip circuit, and an acoustic reminder module, wherein...

[0006] The boost circuit is connected to the main chip circuit and the power input node in the remote key, respectively, and is used to power the voice chip circuit.

[0007] The voice chip circuit generates a reminder command when it receives the voice retrieval command from the remote key;

[0025] Optionally, the power supply module is a button battery.

[0026] A second aspect of this application provides a vehicle that includes the aforementioned voice-retrieval remote key.

[0027] Therefore, the boost circuit in this application is connected to the main chip circuit and the power input node inside the remote key, respectively, and supplies power to the voice chip circuit. The voice chip circuit generates a reminder command when it receives a voice retrieval command from the remote key. The acoustic reminder module is connected to the voice chip circuit and provides acoustic reminders based on the reminder command. Thus, by boosting the battery voltage through the boost circuit to meet the operating voltage requirements of the voice chip, and combining this with the main control chip to achieve voice interaction functionality, this solves the problem in related technologies where keys, due to size and voltage limitations, cannot integrate voice retrieval functions, thereby improving user convenience.

[0028] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0035] The present application is described in detail below, with examples shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description with reference to the accompanying drawings is exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0036] The following description, with reference to the accompanying drawings, describes a voice-retrieval remote key and vehicle based on this application. Addressing the issue mentioned in the background art where keys, due to size and voltage limitations, cannot integrate voice retrieval functionality, this application provides a voice-retrieval remote key. In this application, a boost circuit is connected to both the main chip circuit and the power input node within the remote key, supplying power to the voice chip circuit. The voice chip circuit generates a reminder command upon receiving a voice retrieval command from the remote key. An acoustic reminder module is connected to the voice chip circuit and provides acoustic reminders based on the reminder command. Thus, by boosting the battery voltage through the boost circuit to meet the operating voltage requirements of the voice chip, and combining this with the main control chip to achieve voice interaction functionality, the problem of keys being unable to integrate voice retrieval functionality due to size and voltage limitations in related technologies is solved, improving user convenience.

[0037] Specifically, Figure 1 A block diagram illustrating a voice-activated remote key provided in this application.

[0038] like Figure 1 As shown, the voice-retrieval remote key 10 includes: a boost circuit 100, a voice chip circuit 200, and an acoustic reminder module 300.

[0039] Among them, the boost circuit 100 is connected to the main chip circuit and the power access node in the remote key, respectively, and is used to power the voice chip circuit 200.

[0040] The voice chip circuit 200 generates a reminder command when it receives a voice retrieval command for the remote key;

[0041] The acoustic reminder module 300 is connected to the voice chip circuit 200, and the acoustic reminder module 300 provides acoustic reminders based on reminder commands.

[0042] Specifically, the boost circuit 100, by connecting the main chip circuit inside the remote control key and the power input node, boosts the 3V voltage provided by the battery to 3.3-5V, providing a stable operating voltage for the voice chip circuit 200. The main chip, i.e., the microcontroller, provides control over the driver chip for the entire circuit, performing different combinations of control actions in different applications, thus controlling and distributing the orderly operation of the entire circuit. The voice chip circuit 200 has a built-in voice recognition function, such as... Figure 2 As shown, Figure 2This is a schematic diagram of the radio frequency chip and crystal oscillator circuit of a voice-retrieval remote key according to this application. In the voice chip IC300 of this application, PIN1 and PIN2 are programming ports (PINs are interfaces brought out from inside the chip to connect to external circuits). To save costs, the wake-up word does not need to be changed in subsequent use. Therefore, programming ports are not required, and the wake-up word can be directly set to a factory-specific wake-up word, such as "little fox". When a user issues a specific wake-up word or other voice retrieval command, a corresponding reminder command will be generated immediately. The acoustic reminder module 300 is directly connected to the voice chip circuit 200. After receiving the reminder command, it will emit an acoustic prompt signal through a sound-emitting device to help the user quickly locate the remote key. This application effectively solves the pain point of users finding keys inconveniently by using boost power supply and a voice interaction system without changing the basic functions of traditional remote keys.

[0043] It should be noted that, as Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of the overall circuit architecture of a voice-retrieval remote key according to this application. Figure 4 This is a schematic diagram of the main chip circuit of a voice-retrieval remote key according to this application. Pins 1 to 4 of the main chip IC100 implement the button function of the remote key. That is, when S1 (switch1) is closed, it means that PIN1 is connected to ground (GND). For example, assuming that S1 implements the unlocking function, then the main chip IC100 will communicate with the remote key via SPI after S1 is closed. Figure 4 The RF chip (IC200) shown sends commands. The main chip IC100 interacts with the RF chip via SPI communication through pins 9 to 11. Upon receiving the command from the main chip IC100, the RF chip, in conjunction with an inductor, sends a signal in the same frequency band as the car. At this point, the key will successfully send an unlock signal. After successfully unlocking, the RF chip will also send a successful unlock signal back to the main chip IC100 via SPI communication. The other three switches operate on the same principle. Communication between the voice chip and the main chip is established through the combined operation of P15_CLK (clock signal), P12_RX (signal sent from the voice chip to the main chip, meaning the main chip is the receiver), and P13_TX (signal sent from the main chip to the voice chip, meaning the main chip is the transmitter) within the main chip IC100.

[0044] Optionally, the boost circuit 100 includes: a first diode, the cathode of which is connected to the voltage input pin of the voice chip circuit; a first inductor, one end of which is connected to a power supply access node, and the other end of which is connected to the anode of the first diode; a first MOSFET, the drain of which is connected to the anode of the first diode and the other end of the first inductor, and the source of which is connected to a ground node; a first resistor, one end of which is connected to the gate of the first MOSFET, and the other end of which is connected to the voltage output pin of the main chip circuit; and a first capacitor, one end of which is connected to the cathode of the first diode, and the other end of which is connected to a ground node.

[0045] Among them, such as Figure 2 As shown, Figure 2 This is a schematic diagram of the radio frequency chip and crystal oscillator circuit of a remote control key with voice retrieval capability according to this application. The boost circuit 100 includes a first diode D301, a first inductor L301, a first MOSFET T301, a first resistor R301, and a first capacitor C301.

[0046] It is understandable that, such as Figure 2 As shown, pin 24 is connected to boost circuit 100 to provide a 3.3V-5V operating voltage to the voice chip. The working principle is that VBAT is supplied with 3V from the button battery in the key, which powers the RF chip IC300, which operates at 3.3-5V. The main chip IC100 continuously outputs 0V and 2.3V alternately at a certain frequency through pin 8. This is to keep the MOSFET T301 constantly in a state of open and closed (the turn-on voltage of the MOSFET used in this application is calculated as 0.7V; if the turn-on voltage is different, the voltage output from pin 8 can be adjusted). The cathode of the first diode is connected to the voltage input pin of the voice chip circuit, i.e. Figure 2 The first resistor is connected to pin P24 in the circuit, and the second resistor is connected to the voltage output pin of the main chip circuit. Figure 3 The main chip IC100 is connected to pin P8; the MOSFET in this application turns the circuit on (i.e., acts as a switch), and the voltage level of the original 3V is determined by the switching frequency of T301.

[0047] Optionally, the acoustic alert module 300 is a speaker.

[0048] Understandably, when a user issues a specific wake-up word or other voice retrieval command, the acoustic reminder module 300 is driven to emit a sound through the audio output pin. At the same time, the main chip circuit can adjust the frequency and duty cycle of the output signal to control the pitch and rhythm of the prompt sound, thereby achieving a clear and distinguishable acoustic positioning function.

[0049] Optionally, the voice-retrieval remote key 10 also includes an optical reminder module, which is connected to the voice chip circuit 200 and provides optical reminders based on reminder commands.

[0050] Optionally, the optical alert module is an LED light.

[0051] Understandably, when the voice chip circuit 200 recognizes a specific wake-up word or other voice retrieval command, it simultaneously generates an acoustic reminder command and an optical reminder command. After receiving the command, the optical reminder module flashes and emits light. The LED light can use multi-color LEDs to achieve different color flashing modes. Its on / off frequency and color change are controlled by the main chip circuit to further enhance visual recognition.

[0052] Optionally, the voice-retrieval remote key 10 further includes: an RF chip circuit connected to the main chip circuit, which is used to send at least one of the vehicle unlocking command, vehicle locking command, and vehicle retrieval command generated by the main chip circuit to the vehicle.

[0053] Optionally, the voice-retrieval remote key 10 also includes a crystal oscillator connected to an RF chip circuit.

[0054] It is understandable that in this application, the RF chip communicates with the main chip circuit via SPI (Serial Peripheral interface) (a communication method between the main chip and peripheral driver chips in a serial manner, used for data exchange and communication between chips) to send a frequency band signal of a certain value. Vehicles receiving this frequency band will adjust and match; when the frequency band signals match, the unlocking action is completed, thus playing the role of transmitting frequency band signals in the circuit. The crystal oscillator in this application processes the interactive data rhythmically and orderly, similar to a traffic light.

[0055] Optionally, the voice-retrieval remote key 10 also includes a power supply module, which is connected to the boost circuit 100, the main chip circuit, the radio frequency chip circuit, and the crystal oscillator, respectively, and is used to supply power to the main chip circuit, the radio frequency chip circuit, and the crystal oscillator.

[0056] Optionally, the power supply module is a button battery.

[0057] Understandably, the power supply module provides a 3V operating voltage to the main chip circuit to execute logic control functions, powers the radio frequency chip circuit to realize wireless signal transmission and reception, and provides a stable power supply to the crystal oscillator to ensure clock accuracy. This power supply architecture not only ensures the normal operation of the traditional remote control function module, but also supports the newly added voice interaction function through efficient voltage conversion. All modules are powered by a single button battery, ensuring optimized control of the overall power consumption of the system while maintaining the compact size of the key.

[0058] Therefore, as Figure 5 As shown, Figure 5 This is a circuit design schematic diagram of a voice-retrieval remote key according to this application. It mainly includes a main chip circuit, an RF chip circuit, a voice chip circuit, and a crystal oscillator. The main chip (IC100), RF chip (IC200), and voice chip (IC300) communicate via SPI. The RF chip IC200 is connected to the crystal oscillator and inductors via hardwired connections, achieving normal remote key functionality based on the same control principle as traditional remote keys. The main chip IC100 and voice chip IC300 can communicate via either SPI or hardwired connections. The voice chip IC300 is connected to a boost circuit via hardwired connections. The boost circuit's function is to increase the 3V voltage provided by the button battery in the remote key to 3.3V to 5V, providing the normal operating voltage for the voice chip IC300. Therefore, this application does not limit the operating voltage of the voice chip IC300. By having the main chip IC100 continuously alternately output high and low voltages to keep the boost circuit functioning normally, the normal operating voltage for the voice chip IC300 can be provided. This allows automotive companies to increase their selling points at a lower cost, better allowing users to experience "technology changing lives."

[0059] According to the voice-retrieval remote key proposed in this application, the boost circuit is connected to both the main chip circuit and the power input node within the remote key, supplying power to the voice chip circuit. The voice chip circuit generates a reminder command upon receiving a voice retrieval command from the remote key. An acoustic reminder module is connected to the voice chip circuit and provides acoustic reminders based on the reminder command. Thus, by boosting the battery voltage through the boost circuit to meet the operating voltage requirements of the voice chip, and combining this with the main control chip to achieve voice interaction functionality, this solves the problem in related technologies where keys, due to size and voltage limitations, cannot integrate voice retrieval functionality, thereby improving user convenience.
