[0024] Before explaining the technical solutions of the embodiments of this application, the concept of the embodiments of this application will be explained first.

[0025] With the booming development of the new energy vehicle industry, a new round of technological development is driving the transformation and upgrading of traditional manufacturing to intelligent manufacturing. New energy vehicles, with their internet and intelligent control technologies, are an indispensable part of this wave of technological iteration. Among these advancements, how car keys can more intelligently, conveniently, and securely monitor vehicle information and achieve remote control, enabling intelligent interaction between people and vehicles, will be a key aspect of the intelligent and connected development of new energy vehicles. Current key terminals offer only a single method of vehicle control, resulting in a poor user experience. Therefore, providing users with a more intelligent key terminal and vehicle control experience is an urgent problem to be solved.

[0026] In view of this, this application proposes a key terminal, which includes: an interaction module, a communication module, and a baseband module; the baseband module is connected to both the communication module and the interaction module; the interaction module is used to realize interaction between the user and the key terminal; the baseband module is used to generate vehicle data in response to user instructions or preset trigger conditions obtained through the interaction module, the vehicle data including vehicle control instructions, the vehicle control instructions being used to instruct the vehicle to perform operations corresponding to the vehicle control instructions; the communication module is used to realize data communication between the key terminal and the vehicle, the communication module including at least two of a Bluetooth unit, a radio frequency unit, a near-field communication (NFC) unit, an ultra-wideband (UWB) unit, and an infrared unit, wherein the Bluetooth unit is used to transmit vehicle data with the vehicle via Bluetooth signals, the radio frequency unit is used to transmit vehicle data via radio frequency signals, the NFC unit is used to realize vehicle data transmission when the key terminal is close to the NFC reader of the vehicle, the UWB unit is used to transmit vehicle data with the vehicle via UWB, and the infrared unit is used to transmit vehicle data to the vehicle via infrared light signals. The above technical solution incorporates multiple short-range communication methods, such as NFC, Bluetooth, UWB, infrared, and long-range communication radio frequency units into the optional scheme, forming multiple backup communication schemes. When a certain communication method fails due to environmental interference or hardware failure, the alternative communication link can be flexibly activated, thereby greatly improving the robustness and fault tolerance of the entire vehicle control system and providing users with a more intelligent vehicle control experience.

[0027] Please see Figure 1 , Figure 1 This application provides an example of an application scenario, including a key terminal 110, a vehicle 120, and a terminal device 130. The key terminal 110 can communicate with the vehicle 120. For example, the key terminal 110 sends a vehicle unlocking command to the vehicle. After receiving the vehicle unlocking control command, the vehicle performs the corresponding operation and sends the execution result back to the key terminal 110. The terminal device 130 can be used to control the key terminal. For example, the terminal device can query relevant information about the key terminal, or in the case of a lost key, the terminal device can be used to locate the key terminal.

[0028] For example, the terminal device can be a mobile phone, smartwatch, or other device with communication capabilities.

[0029] For example, the key terminal can be designed as a wearable bracelet; it can also be an oval streamlined shape that naturally fits the palm of the hand; the rounded shape makes it less likely to snag on other items in pockets or bags. A screen and buttons can be integrated on the front, with the main control button arranged on the side; it can also be in a polygonal form, but this embodiment is not limited to this.

[0030] For example, the key terminal 110 may include an interaction module 113, a communication module 111, and a baseband module 112, with the baseband module 112 connected to the communication module 111 and the interaction module 113 respectively.

[0031] Please continue reading. Figure 2 The key terminal 110 shown includes the following modules: interaction module 113, communication module 111, and baseband module 112: The interaction module 113 is used to enable interaction between the user and the key terminal 110.

[0032] For example, users can record voice input through the interaction module 113 to interact with the key terminal 110. For instance, if a user wants to unlock the vehicle through the key terminal 110, they can record a voice command: "Unlock the vehicle." The vehicle can recognize and execute the corresponding voice command input by the user and send the execution result to the key terminal 110, thus realizing the interaction between the user and the key terminal 110.

[0033] For example, users can interact with the key terminal 110 through physical buttons or the screen on the key terminal 110.

[0034] The interaction module 113 is connected to the baseband module 112. The baseband module 112 is used to generate vehicle data in response to user commands or preset trigger conditions obtained through the interaction module 113. The vehicle data includes vehicle control commands, which are used to instruct the vehicle to perform operations corresponding to the vehicle control commands.

[0035] For example, vehicle data also includes status data, which describes the current status and attributes of the vehicle, key terminal 110, and the communication link itself. This status data may include, but is not limited to: the key terminal 110's unique identifier, digital certificate, and current authentication status (e.g., authenticated / unauthenticated / authentication failed); the key terminal 110's battery level, hardware functionality, firmware version number, etc.; the signal strength, connection stability, and data packet loss rate of communication with the key terminal 110 and the cloud server; the baseband module 112's operating mode (normal / low power / sleep), system time, internal temperature, whether an abnormal restart occurred, and other relevant data of the key terminal, as well as the execution results of vehicle control commands.

[0036] For example, vehicle control commands are used to instruct the vehicle to perform operations corresponding to the vehicle control commands. Vehicle control commands can be voice commands or button commands, such as unlocking / locking the vehicle, opening the trunk, preparing the vehicle to start, and opening personalized settings, such as the seats and rearview mirrors.

[0037] The baseband module 112 is used to generate vehicle data in response to user commands or preset trigger conditions obtained through the interaction module 113. The baseband module 112 may include a baseband chip. The baseband chip is the core integrated circuit chip in the mobile device responsible for processing baseband signals. Its core function is to process the received or transmitted baseband signals, specifically including signal encoding and decoding, communication protocol parsing and execution, modulation and demodulation control, and compatibility adaptation with multiple network standards and frequency bands.

[0038] For example, the baseband chip preferentially uses the low-power cat.1. When selecting a cellular network solution for remote communication (communication with a cloud server) for a key terminal, a Cat.1 communication module based on a 4G LTE network should be preferred. The low-power cat.1 achieves the best balance between power consumption, cost, and performance.

[0039] For example, by activating the voice function via a button, the user issues a voice command such as "lock the car" or "close the vehicle." The key terminal 110 receives the voice input codec from the microphone, which converts it into a digital signal and sends it to the vehicle via the baseband module 112 and the communication module 111.

[0040] The communication module 111 is used to realize data communication between the key terminal 110 and the vehicle 120. The communication module 111 may include: a Bluetooth unit 1111, a radio frequency unit 1113, a near-field communication (NFC) unit 1115, an ultra-wideband (UWB) unit 1112, and an infrared unit 1114. Specifically, the Bluetooth unit 1111 is used to transmit vehicle data with the vehicle via Bluetooth signals; the radio frequency unit 1113 is used to transmit vehicle data via radio frequency signals; the NFC unit 1115 is used to transmit vehicle data when the key terminal 110 is close to the vehicle's NFC reader; the UWB unit 1112 is used to transmit vehicle data with the vehicle via UWB; and the infrared unit 1114 is used to transmit vehicle data to the vehicle via infrared light signals.

[0041] For example, Bluetooth unit 1111 is responsible for establishing a stable two-way communication link over a medium distance to efficiently transmit vehicle data. For example, Bluetooth unit 1111 may include a Bluetooth chip and a Bluetooth antenna. The vehicle broadcasts via Bluetooth. When the smart key enters the broadcast range, it connects to the smart key's Bluetooth. When the Bluetooth signal strength is greater than the signal strength threshold, it sends a vehicle control command. After leaving the vehicle, the Bluetooth signal strength is no longer sufficient for unlocking, and the vehicle locks.

[0042] For example, the UWB unit 1112 can use its extremely high time resolution to perform centimeter-level positioning and ranging of the key terminal 110, and realize the transmission of vehicle data based on the accurate distance data measured.

[0043] In actual operation, multiple UWB anchor points (fixed receivers) around the vehicle and the UWB unit 1112 in the key terminal 110 perform a precise "time handshake". By calculating the time it takes for the signal to travel between the two devices, or by comparing the tiny time differences in signal arrival at different anchor points, the system can calculate the relative distance and angle between the key and the vehicle, as well as the various anchor points inside the vehicle, with centimeter-level accuracy. If this distance is less than or equal to a threshold, vehicle control commands can be sent to the vehicle based on UWB communication, enabling the transmission of vehicle data with the vehicle via UWB.

[0044] The NFC unit 1115 allows users to authenticate and unlock the vehicle by simply bringing the key close to the NFC reader area on the door when the vehicle battery is depleted or other wireless communications fail. Contact unlocking is also possible via an NFC coil. The smart key contains an NFC chip and an NFC coil, which can be used to unlock the vehicle by copying an NFC card and simulating the card's functionality.

[0045] In addition, the radio frequency unit 1113 provides long-distance communication between the key terminal 110 and the terminal device; the infrared unit provides an additional communication channel. Exemplarily, the radio frequency unit 1113 may include a radio frequency chip, a power amplifier, and a radio frequency antenna: responsible for modulating and demodulating baseband signals and transmitting or receiving radio frequency signals.

[0046] The infrared unit 1114 transmits vehicle data to the vehicle via infrared light signals emitted by an infrared generator, enabling unlocking or locking. Similar to normal unlocking and locking, input is sent to the baseband chip via button press. The baseband chip receives the input and sends a control signal to the infrared generator, achieving short-range unlocking and locking. This ensures that control commands can be reliably received by the vehicle in various environments.

[0047] It should be understood that when remote control is performed (i.e., when the user and vehicle are outside the direct communication range), this process requires cloud intervention. The data generated by the key terminal 110 first needs to be uploaded to the vehicle manufacturer's cloud server center. After the server completes identity verification and command security analysis, it then sends the command to the target vehicle. After the vehicle completes the execution, it also reports the result to the server via the T-BOX, and finally, the server pushes it to the user's key terminal 110, achieving reliable remote control.

[0048] The above technical solution incorporates multiple short-range communication methods, such as NFC, Bluetooth, UWB, infrared, and long-range communication radio frequency units into the optional scheme, forming multiple backup communication schemes. When a certain communication method fails due to environmental interference or hardware failure, the alternative communication link can be flexibly activated, thereby greatly improving the robustness and fault tolerance of the entire vehicle control system and providing users with a more intelligent vehicle control experience.

[0049] In some embodiments, such as Figure 3 As shown, the interaction module 113 includes a microphone 1131 and a speaker 1132, and the key terminal 110 also includes a codec 114. The codec is connected to the baseband module 112, the microphone 1131, and the speaker 1132, respectively. Microphone 1131 is used to acquire user commands represented by sound signals and transmit the sound signals to the codec. The codec is used to encode and decode the sound signals, and the speaker is used to output the sound signals processed by the codec.

[0050] Microphone 1131 is the input endpoint of the interaction module 113. Its core function is to collect user commands in the form of sound, such as "open the car window" or "find the vehicle", and convert the physical sound wave vibrations in the air into continuous, weak analog electrical signals.

[0051] When a user presses the voice button and speaks, the microphone 1131 captures these sound waves in real time and completes the sound-to-electric conversion. It then transmits the generated raw analog audio signal to the next processing stage: the codec.

[0052] The codec is located between the microphone 1131, the speaker 1132, and the baseband module 112, and is used for bidirectional conversion between analog and digital signals. It converts the microphone's analog signals into digital signals and the digital signals into analog signals for output through the speaker.

[0053] After receiving the analog audio signal from the microphone, the codec 114 preprocesses it, such as amplifying and filtering, to improve the signal-to-noise ratio. Next, it performs the core encoding operation, converting the continuous analog signal into a discrete digital data stream composed of 0s and 1s using techniques such as pulse code modulation. This digitized data format can then be understood and processed by the baseband module 112.

[0054] When sound is needed, such as a vehicle confirmation tone or status prompt, the codec performs the reverse operation. It receives digital audio data from the baseband module 112, decodes it to restore it to an analog electrical signal, and then drives the speaker 1132 to emit sound.

[0055] The codec is directly connected to the microphone 1131, speaker 1132 and baseband module 112 respectively, and is the core hub in the audio path.

[0056] The speaker 1132 is the output terminal of the interaction module 113, responsible for converting the electrical signal processed (decoded) by the codec back into sound waves that can be heard by the human ear.

[0057] Whether it's the confirmation tone issued by the key terminal 110 after the user's command is successfully executed, or the status information returned by the vehicle, such as the voice-synthesized reply "command executed", it will ultimately be sent to the codec by the baseband module 112. The decoded analog signal drives the diaphragm of the speaker to vibrate, thereby playing it clearly and completing the information interaction and feedback loop with the user.

[0058] The baseband module 112 is connected to the codec via a bus to receive and process all digitized audio information.

[0059] For example, in a voice command scenario, the key terminal obtains digitized user command data from the codec. Subsequently, two operations can be performed: first, local voice recognition is performed on the key terminal 110 to directly interpret the meaning of the command; second, the audio data is sent to the vehicle or cloud via the communication module 111, such as via Bluetooth, for more complex recognition. After the command is recognized, the baseband module 112 generates the corresponding vehicle control command or query request and sends it to the vehicle via the communication module 111. Simultaneously, it also uses the received execution results and other information to trigger the codec and speaker, providing voice prompts to the user.

[0060] In the above technical solution, the collaborative system consisting of a microphone, codec, speaker, and baseband module 112 can upgrade a traditional one-way remote control key into a smart terminal with two-way voice communication capabilities. Users can issue commands through natural voice and receive clear status feedback through sound, greatly improving ease of use.

[0061] In addition to the microphone and speaker for interaction between the key terminal 110 and the user, the interaction module 113 can also be controlled via buttons. The following details the interaction between the user and the key terminal 110 via buttons.

[0062] In some embodiments, such as Figure 4 As shown, the interaction module 113 includes at least one physical button, which includes at least one of the following: unlock button 1, lock button 2, remote button 3, voice wake-up button 4, and main control button 5. The unlock button is used to send vehicle unlock control commands, the lock button is used to send vehicle lock control commands, the remote button is used to wake up remote functions, the voice wake-up button is used to wake up voice functions, and the main control button is used to control the key terminal 110.

[0063] The unlock button is used to send vehicle unlocking control commands. It is one of the core triggers for implementing keyless entry. When the user presses the unlock button, an electrical signal is immediately sent to the baseband module 112. The baseband module 112 then responds, generating an encrypted data packet (vehicle data) containing the "door unlock" command, and sends it to the vehicle via the communication module 111, such as the radio frequency or UWB unit 1112. After the vehicle verifies the command's validity, it performs the unlocking operation, usually accompanied by a brief feedback of lights or a horn to indicate success.

[0064] The door lock button is used to send vehicle locking control commands and is a key button for ensuring vehicle safety. After pressing the door lock button, similar to the unlocking process, the baseband module 112 generates and sends a "door lock" command. The vehicle executes the locking action, and may confirm successful operation by flashing hazard lights or automatically folding the side mirrors. In some advanced implementations, it will first check that all doors, the trunk, and the hood are completely closed before executing the locking action to ensure safety.

[0065] The remote button is used to activate remote functions. It typically doesn't directly correspond to a simple on / off action, but rather activates functions that require complex communication with a remote vehicle or cloud server. Pressing the remote button wakes up the baseband module 112, putting it into a specific operating mode. For example, it can trigger the key terminal 110 to send a request to the vehicle via a mobile network or in conjunction with a mobile app to remotely start the engine, turn on the air conditioning, or preheat / cool the seats. This command chain is relatively long and requires relay and confirmation from the cloud server; therefore, this button acts as a switch to initiate this complex process.

[0066] The voice wake-up button is used to activate the voice function, perfectly combining the convenience of physical buttons with the naturalness of voice interaction. For example, when a user presses or holds this button, the baseband module 112 activates the voice recognition subsystem. The baseband module 112 then activates the codec and microphone, ready to receive the user's voice commands.

[0067] The main control button is a multi-functional button used for global control of the key terminal 110 itself. It typically undertakes system-level management tasks.

[0068] For example, the functions of the main control button are often distinguished by different operation methods such as short press, long press, or double press. Common functions include: a long press to turn the key terminal 110 on or off; a short press to cycle between different operating modes, such as normal mode and energy-saving mode; and a long press to put the key into Bluetooth discoverable mode for Bluetooth pairing with a mobile phone or vehicle. In cases where the key terminal 110 includes a screen, the main control button can be used to wake up the screen.

[0069] On some minimalist key designs, it can also be used in combination with other buttons to trigger more hidden functions.

[0070] In some embodiments, the interaction module 113 integrates multiple physical buttons with clearly defined functions, such as an unlock button, a lock button, a remote button, a voice wake-up button, and a main control button. Through these buttons, users can quickly trigger the corresponding core functions: the unlock and lock buttons are used to directly send vehicle door lock control commands; the remote button can wake up the remote control function; the voice wake-up button is used to initiate the voice interaction mode; and the main control button facilitates overall management of the key terminal 110 itself. This not only significantly improves the intuitiveness and response speed of operation, allowing users to complete frequently used functions with a single click without relying on complex menus, effectively reducing the possibility of misoperation; but also, the combination of voice and physical button interaction allows for adaptation to more diverse usage scenarios, such as blind operation while driving or environments with poor network signals, thereby greatly enhancing the usability and reliability of the key terminal 110 while ensuring functional completeness.

[0071] In some embodiments, continue to refer to Figure 4 The interaction module 113 also includes a screen 1133, and at least one physical button is located in an area outside the screen.

[0072] The screen can clearly and comprehensively display a wealth of visual information such as vehicle status, key terminal battery level, or function menu; while independent physical buttons allow users to perform quick button operations.

[0073] In some embodiments, such as Figure 4 As shown, the key terminal 110 also includes: a housing 11 and a printed circuit board (PCB) (not shown) housed within the housing, wherein, At least one physical button is disposed on the housing at a distance from the screen, and the communication module 111 and the baseband module 112 are disposed on the PCB board.

[0074] The housing 11 is the external structural component of the key terminal 110, typically made of high-strength engineering plastics or metals through precision injection molding or die casting. It encapsulates all the delicate electronic components, forming a robust whole that effectively resists environmental factors such as drops, scratches, dust, and moisture during daily use. The design of the housing directly determines the user's operating interface. For example... Figure 4 As shown: A precise display window is reserved for the screen, usually covered with a high-transmittance glass or acrylic cover for protection.

[0075] At least one physical button, such as an unlock button or a lock button, has a hole or a pre-drilled area for a microswitch. These physical buttons and the screen can be spaced apart on the housing to clearly separate the visual feedback area (screen) from the tactile operation area (button), preventing accidental touches by the user and allowing the thumb to move naturally between viewing and pressing when operating with one hand, greatly improving the intuitiveness and convenience of operation.

[0076] A printed circuit board (PCB) is an insulating board covered with precision circuitry and solder joints, used for electrical connections and mechanical fixation of all core electronic components. The PCB integrates key modules that determine the intelligent functions of the key terminal 110: a baseband module 112 and a communication module 111. The baseband module 112, acting as the main controller, is typically soldered onto the PCB as a highly integrated system-on-a-chip (SoC) or microprocessor. The communication module 111 contains related chips for Bluetooth, UWB, and radio frequency (RF) communication units, as well as RF front-ends and antenna circuits. These components are precisely laid out on the PCB to ensure optimal wireless signal performance and interference resistance.

[0077] The aforementioned technical solution not only ensures the device's robustness, durability, aesthetics, and ease of use, but also provides a stable and reliable physical platform for more complex wireless communication and data processing functions. On one hand, it achieves a compact and reliable overall structure, with all core electronic units centrally fixed on the PCB, which is beneficial for signal integrity and electromagnetic compatibility control, improving the stability and lifespan of the terminal. On the other hand, the buttons and screen are arranged alternately on the casing, which not only optimizes panel space and prevents accidental touches, but also facilitates assembly and standardized production, thereby ensuring the product is lightweight and compact while enhancing the overall structural stability and manufacturability.

[0078] The layout of at least one physical button and screen on the key terminal 110 is described in detail below.

[0079] In some embodiments, such as Figure 4 As shown, at least one physical button includes at least one of the following: unlock button 1, lock button 2, remote button 3, voice wake-up button 4, and main control button 5.

[0080] At least one physical button is located on one side of the front of the housing, and the screen is located on the other side of the front of the housing.

[0081] For example, one side of the front of the housing may be the upper half of the front of the housing, and the other side of the front of the housing may be the lower half of the front of the housing.

[0082] The main control buttons can be located on the side of the casing, outside the screen, with the side of the casing connected to the front.

[0083] For example, the housing has four sides: a top side, a bottom side, a left side, and a right side, and the main control button can be located on the right side.

[0084] Figure 4 The layout of the physical buttons and the screen is merely an example. At least one physical button is located on the lower side of the front of the housing, or on the right side, which is on the same side as the main control button, or on the left side. The main control button is located on the side of the housing other than the screen. This side can be the left side, the upper side, or the lower side. This application does not limit the specific implementation.

[0085] In the above technical solution, the physical button layout of the key terminal 110 is such that the function buttons for unlocking, locking, remote control and voice wake-up are centrally located on one side of the front of the housing, while the screen is located on the other side of the front. The main control button is independently arranged on the side of the housing connected to the front, which takes into account both the convenience of one-handed operation and the logic of the interactive interface, and brings users an efficient and reliable user experience.

[0086] The above describes a layout of a key terminal 110 in which at least one physical button is located outside the screen area. The following describes another layout of the screen and physical buttons.

[0087] In other embodiments, such as Figure 5 As shown, at least one physical button includes the main control button 5; The main control button 5 is located on the side of the casing, outside the screen; The screen 1133 is embedded in the housing. After the screen is woken up by the main control button, the screen is used to display at least one control. The at least one control includes at least one of the following: unlock control 6, lock control 7, remote control 8, and voice wake-up control 9. The unlock control 6 is used to send vehicle unlock control commands, the lock control 7 is used to send vehicle lock control commands, the remote control 8 is used to wake up the remote function, and the voice wake-up control 9 is used to wake up the voice function.

[0088] In this embodiment, the front of the casing has no physical buttons except for an embedded screen, creating a clean and unified appearance. All interactive functions are integrated into the screen and the main control buttons on the side. In the screen-off state, the device has an extremely simple appearance; when needed, a rich set of virtual controls appears on the screen through a specific wake-up operation.

[0089] The main control button is the only physical button retained in this embodiment, and it is located on the side of the casing outside the screen. This location is convenient for touch and effectively prevents accidental touches from inside a pocket. The primary function of this main control button is to wake up the key terminal 110 from its dormant state. A short press or long press of this button will send a wake-up signal to the baseband module 112. Similar to previous embodiments, it still performs system-level control tasks, such as long press to power off and mode switching.

[0090] The screen is embedded in the housing, with the display surface flush with or on the same plane as the housing surface, achieving a seamless connection that is not only aesthetically pleasing but also enhances impact resistance and durability.

[0091] In sleep mode, the screen can be completely black to save power, at which point the key terminal 110 looks like a smooth "black box". When awakened by the main control button, the screen lights up and becomes a dynamic graphical control interface.

[0092] Once the screen is activated, the virtual controls it displays completely replace the physical buttons in traditional implementations. These controls are graphical buttons that are perceived through touchscreen technology.

[0093] Unlock control: Used to send vehicle unlocking control commands. Touching this virtual button has the same effect as pressing a physical unlock button. UI designers can add dynamic effects, such as a ripple animation when touched, or a color change after use, such as changing from gray (when not in use) to green (when unlocked), providing richer visual feedback.

[0094] Locking Control: Used to send vehicle locking control commands. The display of this control can intelligently change according to the vehicle's status. For example, when the vehicle is already locked, this control can be displayed as grayed out and unavailable, avoiding duplicate command transmissions.

[0095] Remote controls: Used to activate remote functions. Touching it triggers a complex process of communication with the cloud server, such as remotely starting the engine or pre-activating the air conditioner. The execution status of the remote function can be displayed directly next to the control, such as text prompts like "Command being sent..." or "Execution successful," making the interaction process more transparent.

[0096] Voice wake-up control: Used to activate voice functionality. Touching the voice wake-up control activates the microphone and voice recognition system, preparing to receive user voice commands. Changing voice wake-up from "long-pressing a physical button" to "touching a virtual button" aligns more with the habits of modern smart devices.

[0097] In this embodiment, the main control button is independently located on the side of the housing, while the screen is embedded in the front. When the user wakes up the device using the side main control button, the screen dynamically displays virtual controls including functions such as unlocking, locking, remote control, and voice wake-up. In standby mode, thanks to the physical properties of the side main control button and its anti-accidental touch features, the device's power consumption is effectively controlled, resulting in a clean and simple appearance. After being woken up, the screen provides a rich and customizable interactive interface (such as adjustable control types and layouts), greatly expanding its functional capabilities. Furthermore, this hardware-software integrated interaction logic significantly improves user intuition and operational efficiency. Users only need to remember the core action of "wake up with the main control button" to complete all complex operations under the guidance of the screen, maximizing functionality and user experience within a limited hardware space.

[0098] In some embodiments, to further enhance the communication reliability and functional integrity of the smart key terminal 110 in specific scenarios, such as Figure 5 As shown, the key terminal 110 also includes: Infrared emitter 12, the infrared emitter is located on the side of the housing.

[0099] For example, the infrared transmitter 12 can be on the same side as the main control button mentioned above, or it can be on a different side. For example, the infrared generator can be an infrared light-emitting diode.

[0100] Infrared transmitter 12 is a component that uses infrared light pulses to transmit data. In smart key terminal 110, it is usually not used as the primary communication method, which is Bluetooth, UWB, etc. Instead, it plays a role as a highly reliable and highly directional backup communication method.

[0101] Its operation is similar to that of a traditional television remote control. When the user presses a function key, such as unlocking, the baseband module 112 encodes the corresponding control command into a specific digital signal, which drives the light-emitting diode inside the infrared transmitter to convert it into a series of infrared light pulses invisible to the human eye and emit them outward. The infrared receiver window on the vehicle receives these light pulses and then decodes them back into the command.

[0102] Infrared light is unaffected by radio frequency interference. In environments with numerous complex wireless signals, such as underground garages and parking lots, infrared communication can serve as a highly reliable supplement when radio frequency communication may be interfered with.

[0103] In addition, infrared light has the characteristic of straight-line propagation and a narrow beam. This means that the user must roughly point the key terminal 110 at the vehicle to complete the operation, which implicitly constitutes a simple form of identity verification (the user is right next to the car), and can prevent relay attacks to a certain extent.

[0104] The infrared transmitter is located on the side of the housing. When the user holds the key and intends to use the infrared function, they will naturally point the side of the key at the vehicle, which is completely consistent with the habit of using a remote control.

[0105] Placing the transmitter on the side ensures that the hand will not block the transmission window when holding it normally, thus guaranteeing a clear signal.

[0106] For example, the main control buttons can be on the same side. This layout concentrates all physical interfaces that require active and conscious user operation (main control buttons, infrared window) on one side, making it easier for users to remember and locate them. Users only need to remember that "all side operations are on this side".

[0107] For example, placing the main control buttons on a different side from the main control buttons allows for physical partitioning of functions. For instance, placing the main control buttons on the right side facilitates operation with the right thumb, while placing the infrared transmitter on the top side makes it more naturally pointed towards the vehicle. This design distributes functional points, allowing more space for each component and potentially resulting in a more symmetrical and aesthetically pleasing appearance.

[0108] Combining the above embodiments with an infrared transmitter can greatly improve the reliability of the smart key terminal 110 in multiple scenarios.

[0109] In some embodiments, such as Figure 6 As shown, the key terminal 110 also includes: GPS unit 1116 is used for positioning of key terminal 110, and GPS unit 1116 is connected to baseband module 112.

[0110] GPS unit 1116 is a satellite signal receiver whose core function is to receive signals from the Global Positioning System satellite constellation and calculate the latitude and longitude coordinates, altitude, and precise time of the key terminal 110 using triangulation. It provides the key terminal 110 with global, passive (without user intervention) location awareness capabilities.

[0111] The GPS unit's antenna continuously receives broadcast signals from multiple GPS satellites. The internal processor analyzes the transmission time differences of these signals to accurately calculate the distance to each satellite, thereby determining the precise geographical location of the key terminal 110 itself.

[0112] The calculated location data (latitude and longitude, etc.) is transmitted to the baseband module 112. As a decision center, the baseband module 112 can process this location data according to preset rules or in response to remote commands from users.

[0113] For example, the most direct and important value of integrating a GPS unit is that it can solve the pain point of traditional keys being difficult to find after they are lost.

[0114] When a user discovers their key is lost, they can search for it using the following process: Step 1: User initiates location request: The user opens the associated app on their mobile device (phone) and triggers the "Find Key" function. The app then sends an encrypted and authenticated location request to the cloud server via the network.

[0115] Step 2, Server command issuance: After verifying user permissions, the cloud server sends a remote command to the lost key terminal 110 via the mobile network, instructing it to report its current location.

[0116] Step 3, Key terminal 110 responds and reports: The communication module 111 of key terminal 110 receives the instruction from the cloud and transmits it to the baseband module 112.

[0117] The baseband module 112 then wakes up the GPS unit (if it is in sleep mode) and commands it to immediately perform one or more location locks. The GPS unit returns the latest latitude and longitude coordinates to the baseband module 112. The baseband module 112 sends this crucial location data back to the cloud server via the communication module 111 (mobile network). The cloud server pushes the received coordinate information to the user's mobile app. The app will then display the key's last known location precisely as a clear pin or marker on a map interface, such as Amap or Google Maps. The user can navigate to the vicinity of this location using the map to search for it.

[0118] In this embodiment, the smart key terminal 110, which integrates a GPS unit, fundamentally changes the predicament of blindly searching for lost keys by combining it with mobile network communication and cloud services. This not only provides great convenience but also significantly improves vehicle security, as vehicle owners can immediately confirm the location of their vehicle keys, thereby assessing risks and taking appropriate measures.

[0119] In some embodiments, such as Figure 7 In addition to the communication module 111, baseband module 112, and interaction module 113, the key terminal 110 shown also includes: The wireless charging module 115 includes a wireless charging module 1151 and a battery 1152. The wireless charging module 1151 is connected to the battery 1152, and the baseband module 112 is connected to both the wireless charging module 1151 and the battery 1152.

[0120] The wireless charging module is the core hardware for enabling wireless charging in the key terminal 110. It is usually embedded in the key housing and mainly consists of a wireless charging chip and a coil. Most vehicles have a built-in wireless charging module, and the smart key can be placed in the wireless charging position to charge, making it convenient to replenish power.

[0121] For example, when a user places the key terminal 110 on a compatible wireless charging base, energy is transmitted across space via electromagnetic induction from the base to the receiving coil inside the key, and then processed by the internal circuitry to finally output appropriate DC power.

[0122] The battery is the energy source for the entire key terminal 110. It can be a rechargeable lithium polymer battery, which has high energy density and is thin and light, making it very suitable for integration into a compact key terminal 110.

[0123] The battery can be directly connected to the output of the wireless charging module to receive and store power from the module. Simultaneously, the battery's output is connected to the power supply circuit of the entire key terminal 110, providing the necessary power for the operation of all electronic components, including the baseband module 112, communication module 111, and screen.

[0124] The baseband module 112 is connected to the wireless charging module and the battery through a dedicated circuit to achieve comprehensive monitoring and management of the charging process and power status.

[0125] For example, the baseband module 112 can continuously monitor key battery parameters, including real-time battery level, voltage, and health status. This information, after processing, is displayed to the user intuitively via the interaction module 113, such as on a screen (e.g., in percentage or icon form).

[0126] For example, based on battery power information, the baseband module 112 can also dynamically adjust system power consumption. For instance, when the battery is low, it can automatically reduce screen brightness, shorten backlight time, or allow the system to enter deep sleep mode more quickly to maximize standby time.

[0127] In some embodiments, the housing is provided with a first sound hole corresponding to a speaker and a second sound hole corresponding to a microphone; the first sound hole and the second sound hole are located on adjacent or opposite sides of the screen.

[0128] In some embodiments, the key terminal 110 further includes a charging port, which is disposed on the side of the key terminal 110 housing corresponding to at least one physical button. This side may be the same side as the main control button or a different side.

[0129] The above description is merely a specific implementation of the embodiments of this application, but the protection scope of the embodiments of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the embodiments of this application should be included within the protection scope of the embodiments of this application. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
