Description

Technical Field

[0001] This utility model relates to the field of vehicle cockpit technology, and in particular to an integrated control device for a cockpit intercom system. Background Technology

[0002] In automotive cockpit applications, the cockpit domain controller is a critical component, and its stability and reliability are paramount. However, due to the complexity and variability of the in-vehicle environment, the cockpit domain controller may be affected by factors such as vibration and high temperatures during prolonged operation, leading to performance degradation or even damage. Therefore, an integrated control device is needed to effectively protect the cockpit domain controller from shock and dissipate heat, ensuring its stable operation over extended periods. Furthermore, some current cockpit domain controllers integrate intercom devices, primarily connecting via the classic Bluetooth HFP (hands-free profile) protocol. However, using the HFP protocol occupies classic Bluetooth channels, easily causing conflicts with in-vehicle connectivity scenarios such as CarPlay and Android Auto. It also only supports narrowband transmission, resulting in relatively poor audio quality, weak cockpit control over intercom devices, and limited functionality.

[0003] Therefore, the cockpit intercom system integrated control device provided in this application is designed to meet this need. Utility Model Content

[0004] The main purpose of this utility model is to propose an integrated control device for a cockpit intercom system, which aims to at least solve the technical problems of traditional cockpit domain controllers being affected by factors such as vibration and high temperature during long-term operation, leading to performance degradation or even damage, as well as the conflicts in traditional cockpit vehicle interconnection scenarios, and the fact that they only support narrowband transmission and have poor control functions.

[0005] To achieve the above objectives, this utility model proposes an integrated control device for a cockpit intercom system, including a cockpit domain controller. The cockpit domain controller is fixedly installed inside a control box via multiple spring shock absorbers. A side cover plate is screwed onto one side of the control box. Several heat dissipation holes are provided on the side wall of the control box facing the side cover plate.

[0006] Two symmetrically arranged cooling fans are embedded in the side cover plate, and there is a gap between the cockpit domain controller and the inner wall of the control box, which serves as a heat dissipation channel.

[0007] The cockpit domain controller is responsible for handling communication and data exchange between the intercom device and the cockpit. It is electrically connected to the intercom device, voice button, audio acquisition unit, voice player, and battery. The battery is also electrically connected to the intercom device, voice button, audio acquisition unit, and voice player. The cockpit domain controller communicates with the intercom device based on the LE Audio TMAP protocol. The intercom devices communicate with each other through analog / digital signals, forming a cockpit communication network topology based on the intercom device.

[0010] In a preferred embodiment of this utility model, the airflow direction of the cooling fan is directed toward the heat dissipation hole. Two symmetrically arranged air guide covers are fixedly installed on the outer side wall of the control box opposite the side cover plate. One end of the two air guide covers is connected to several heat dissipation holes, and the other end of the two air guide covers is curved and extends toward the heating surface of the two semiconductor cooling chips respectively. There is a gap between the end of the air guide cover away from the heat dissipation hole and the heating surface of the semiconductor cooling chip.

[0011] As a preferred embodiment of this utility model, a temperature control switch is fixedly installed inside the control box. The temperature control switch is connected in series with the cooling fan and the thermoelectric cooler.

[0012] As a preferred embodiment of this utility model, two symmetrically arranged L-shaped mounting plates are fixedly installed at the bottom of the control box near its two ends, and elongated waist-shaped mounting holes are opened on the bottom wall of the two L-shaped mounting plates.

[0013] As a preferred embodiment of this utility model, the cockpit domain controller includes a matching interactive application software (APP) for enabling users to interact with the walkie-talkie. The interactive application software (APP) acquires voice information from the walkie-talkie via Bluetooth / audio interface and stores and optimizes the information.

[0014] In a preferred embodiment of this utility model, the walkie-talkie device completes the Bluetooth connection by responding to the pairing request of the cockpit domain controller via BLE.

[0015] As a preferred embodiment of this utility model, the voice button is located in a position within the cockpit that is convenient for the user to operate. When the user presses the voice button, the cockpit domain controller will capture the button event and issue an activation intercom command to put the system into intercom mode.

[0016] As a preferred embodiment of this utility model, the voice player includes a speaker in the cockpit and an audio playback device in the cockpit.

[0017] This utility model has the following beneficial effects:

[0018] The cockpit intercom system integrated control device provided by this utility model, by combining components such as spring shock absorbers, cooling fans, semiconductor cooling chips, air guides, and temperature control switches, achieves effective shock protection and efficient heat dissipation for the cockpit domain controller, ensuring that the cockpit domain controller can work stably for a long time.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0031] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0032] Example 1

[0033] The cockpit intercom system integrated control device provided in this embodiment, such as... Figures 1-3 As shown, the control box 1 includes a cockpit domain controller 9, which is fixedly installed inside the control box 1 by multiple spring shock absorbers 10. A side cover plate 2 is installed on one side of the control box 1 by screws. Several heat dissipation holes 8 are opened on the side wall of the control box 1 facing the side cover plate 2. Two symmetrically arranged cooling fans 3 are embedded in the side cover plate 2. There is a gap between the cockpit domain controller 9 and the inner wall of the control box 1, which serves as a heat dissipation channel.

[0034] The spring shock absorber 10 is used to protect the cockpit domain controller 9 from shock, which can effectively ensure the service life of the cockpit domain controller 9. It is especially suitable for use in vehicle cockpit scenarios. The cooling fan 3 is used to dissipate heat from the cockpit domain controller 9, which can effectively dissipate the heat generated by the cockpit domain controller 9 during long-term operation, thereby ensuring that the cockpit domain controller 9 can work stably for a long time.

[0035] To ensure the shock absorption effect of the cockpit domain controller 9, at least four spring dampers 10 are evenly distributed between the cockpit domain controller 9 and the inner wall of the control box 1. The two ends of the damper in the spring damper 10 are fixedly connected to the inner wall of the cockpit domain controller 9 and the control box 1, respectively, and the springs on the outside of the damper abut against the inner wall between the cockpit domain controller 9 and the control box 1.

[0036] To further ensure the heat dissipation effect of the cockpit domain controller 9, two semiconductor cooling chips 4 are embedded on the two end walls of the control box 1. The cooling surfaces of the semiconductor cooling chips 4 are all facing the inside of the control box 1, and the heating surfaces of the semiconductor cooling chips 4 are all facing the outside of the control box 1.

[0037] To dissipate heat from the heating surface of the thermoelectric cooler 4 and ensure its stable operation, the cooling fan 3 is directed towards the heat dissipation holes 8. Two symmetrically arranged air guide shrouds 5 are fixedly installed on the outer side wall of the side cover plate 2 opposite to the control box 1. One end of the two air guide shrouds 5 is connected to several heat dissipation holes 8, and the other end of the two air guide shrouds 5 is bent in an arc shape and extends towards the heating surface of the two thermoelectric coolers 4 respectively. To ensure that the heat from the heating surface of the thermoelectric cooler 4 can be dissipated, there is a gap between the end of the air guide shroud 5 away from the heat dissipation holes 8 and the heating surface of the thermoelectric cooler 4.

[0038] In order to enable the cooling fan 3 and the thermoelectric cooler 4 to start and stop automatically, a temperature control switch is fixedly installed inside the control box 1. The temperature control switch is connected in series with the cooling fan 3 and the thermoelectric cooler 4.

[0039] To facilitate the installation of the integrated control device for the cockpit intercom system, two symmetrically arranged L-shaped mounting plates 6 are fixedly installed at the bottom of the control box 1 near both ends. At the same time, elongated waist-shaped mounting holes 7 are provided on the bottom wall of both L-shaped mounting plates 6. The elongated waist-shaped mounting holes 7 are used to insert screws to fix the L-shaped mounting plates 6 inside the vehicle. The design of the elongated waist-shaped mounting holes 7 means that the position of the screw holes corresponding to the installation position does not need to be very precise, which can reduce the manufacturing cost and installation difficulty.

[0040] In summary, the cockpit intercom system integrated control device provided in this embodiment, by combining components such as the spring shock absorber 10, cooling fan 3, semiconductor cooling chip 4, air guide shroud 5, and temperature control switch, achieves effective shock protection and efficient heat dissipation for the cockpit domain controller 9, ensuring that the cockpit domain controller 9 can operate stably for extended periods. Simultaneously, the design of the L-shaped mounting plate 6 and the elongated waist-shaped mounting hole 7 makes the installation of this device more convenient, reducing manufacturing costs and installation difficulty.

[0041] Working principle:

[0042] Shockproof protection: The cockpit domain controller 9 is fixedly installed inside the control box 1 by multiple spring shock absorbers 10. The dampers and springs in the spring shock absorbers 10 work together to provide shockproof protection for the cockpit domain controller 9, effectively extending its service life.

[0043] Heat dissipation mechanism: The cooling fan 3 and the thermoelectric cooler 4 together constitute the heat dissipation system. The cooling fan 3 blows air towards the heat dissipation holes 8, carrying away the heat generated by the cockpit domain controller 9; at the same time, the cooling surface of the thermoelectric cooler 4 faces the inside of the control box 1, and the heating surface faces the outside. The air blown by the cooling fan 3 is directed to the heating surface of the thermoelectric cooler 4 through the air guide shroud 5, which further improves the heat dissipation efficiency.

[0044] Temperature control switch: The temperature control switch is connected in series with the cooling fan 3 and the thermoelectric cooler 4. When the temperature of the cockpit domain controller 9 rises to a certain level, the temperature control switch automatically starts the cooling fan 3 and the thermoelectric cooler 4 to dissipate heat; when the temperature drops to a certain level, the temperature control switch automatically shuts them off, realizing the automatic start and stop function.

[0045] Easy installation: The L-shaped mounting plate 6 and the elongated waist-shaped mounting hole 7 make it easy to fix the device inside the vehicle. The elongated waist-shaped mounting hole 7 also makes the installation position more flexible, reducing the installation difficulty and process cost.

[0046] Example 2

[0047] Based on Embodiment 1, Embodiment 2 provides an integrated control device for the cockpit intercom system, such as... Figure 4 As shown, the cockpit domain controller 9 is responsible for handling communication and data exchange between the walkie-talkie device and the cockpit. It is electrically connected to the walkie-talkie device, voice buttons, audio acquisition unit, voice player, and battery. The battery is also electrically connected to the walkie-talkie device, voice buttons, audio acquisition unit, and voice player. Figure 5 and Figure 6As shown, the cockpit domain controller 9 establishes a communication connection with the walkie-talkie device based on the LEAudio TMAP protocol. The walkie-talkie devices communicate with each other through analog / digital signals, forming a cockpit communication network topology based on the walkie-talkie devices.

[0048] The cockpit domain controller 9 has built-in memory and uses the LE Audio protocol in Bluetooth Low Energy (BLE) technology to connect to the walkie-talkie, replacing the traditional HFP protocol. This avoids conflicts with in-vehicle connectivity scenarios such as CarPlay and Android Auto, achieving efficient and low-power voice data transmission and improving audio quality. The walkie-talkie responds to the pairing request from the cockpit domain controller 9 via BLE to complete the Bluetooth connection. The walkie-talkie integrates a LEAudioTMAP protocol stack for receiving and sending voice data. The voice button is located in an easily accessible position within the cockpit. When the user presses the voice button, the cockpit domain controller 9 captures the button event and issues an activation command to put the system into intercom mode. The voice player outputs audio... The output line connects to the speakers in the cockpit or wirelessly transmits voice data to the audio playback device in the cockpit, enabling clear voice playback. The audio acquisition unit is responsible for collecting the user's voice data and simultaneously sending it to the application layer for voice storage, voice-to-text conversion, and other processing. It also transmits the data to the walkie-talkie device via the underlying Bluetooth link to complete the voice transmission function. After receiving the voice signal from the walkie-talkie, the walkie-talkie device transmits it to the cockpit domain controller 9 via the LEAudioTMAP protocol. The cockpit domain controller 9 then plays this voice data through the voice player and simultaneously stores and analyzes the voice data. The battery provides a stable power supply for the entire system, ensuring the normal operation of all components.

[0049] Specifically, in this embodiment, the voice button is connected to the cockpit domain controller 9 via wired or wireless means to ensure accurate transmission of user operation signals. The audio acquisition unit is connected to the cockpit domain controller 9 via audio data cable or wireless means to realize real-time acquisition and processing of voice data. The voice player includes speakers in the cockpit and audio playback devices in the cockpit. The battery provides a stable power supply to each module in the system via power cord or wireless charging, ensuring the continuous and stable operation of the system under various usage scenarios. The various modules in the system are connected and communicate with each other through standardized interfaces and protocols, ensuring the scalability and compatibility of the system.

[0050] The cockpit domain controller 9 can be an NVIDIA Jetson Nano model, which has sufficient processing power to handle communication and data exchange, supports Bluetooth and wireless connectivity, and is suitable for this system; the walkie-talkie device can be a MOTOTRBO model.TM The CP200d digital two-way radio supports BLE connectivity and is suitable for integration with the LEAudioTMAP protocol stack. The voice buttons can be touch-sensitive modules with integrated haptic feedback, connecting to the cockpit domain controller 9 via wired or wireless means. The audio acquisition unit can be an 8-channel analog input module (RevolutionPi-AIO8), suitable for acquiring audio signals and connecting to the controller via fieldbus. Alternatively, a portable Bluetooth speaker (Bose SoundLink Revolve+) can be used as the voice player, providing high-quality audio output and connecting to the cockpit domain controller 9 via Bluetooth.

[0051] The cockpit domain controller 9 includes a supporting interactive application software (APP) for user interaction with the walkie-talkie. The APP acquires and stores voice information from the walkie-talkie via a Bluetooth / audio interface. When the user presses the voice button, the cockpit application triggers a button event and sends an activation command (PPT) to the walkie-talkie, entering intercom mode. The cockpit collects the user's audio and sends it to the APP and the underlying Bluetooth link. The APP stores the voice, converts it to text, and the Bluetooth link transmits the voice data to the walkie-talkie to complete the voice transmission function. The flowchart is shown below. Figure 7 As shown.

[0053] 1. Bluetooth connection established

[0054] The cockpit domain controller 9 initiates a BLE pairing request.

[0055] The walkie-talkie device responds to the pairing request and completes the Bluetooth connection.

[0056] 2. Activate intercom mode

[0058] The cockpit domain controller 9 captures key press events and issues an activation command for the intercom.

[0059] The system has entered intercom mode.

[0060] 3. Voice Acquisition and Transmission

[0061] The audio acquisition device collects user voice data.

[0062] The collected voice data is simultaneously sent to the application layer for voice storage, voice-to-text conversion, and other processing.

[0063] Voice data is transmitted to the walkie-talkie device via the underlying Bluetooth link to complete the voice transmission function.

[0064] 4. Voice reception and playback

[0065] The walkie-talkie device receives voice signals from the other end's walkie-talkie.

[0066] Voice data is transmitted to the cockpit domain controller 9 via the LEAudioTMAP protocol.
