Description

Technical Field

[0001] This utility model belongs to the field of electronic control unit technology, specifically relating to a dual unlocking signal receiving and triggering module and a vehicle. Background Technology

[0002] With the development of automotive intelligence and connectivity, digital keys are gradually replacing traditional physical keys, becoming the mainstream solution for achieving keyless entry and start (PEPS) functionality. Among numerous wireless communication technologies, Bluetooth and Near Field Communication (NFC) have become the two core technologies of current digital key systems due to their security, convenience, and compatibility.

[0003] Bluetooth technology: Based on Bluetooth Low Energy (BLE), it supports short-to-medium range communication (typically within 10 meters, but up to 30 meters under ideal conditions), enabling automatic unlocking and starting of the vehicle. When a user approaches the vehicle with a smart device that supports digital keys, authentication can be completed without active operation, achieving "seamless entry" and "seamless start".

[0004] NFC technology: Based on the principle of radio frequency identification (RFID), it requires the smart device to be placed close to a designated sensing area on the vehicle (within approximately 2 centimeters) for communication authentication. This technology has strong anti-interference capabilities and security, and can still support authentication even when the device is powered off or the wireless communication module fails. Therefore, it is often used as an emergency unlocking method when Bluetooth functionality fails or the device is low on battery.

[0005] Currently, mainstream automakers and technology companies have widely deployed digital key systems based on the integration of Bluetooth and NFC. Some manufacturers use Bluetooth as the primary communication method, supplemented by NFC as a backup channel; others have implemented collaborative operation between Bluetooth and NFC, allowing users to switch freely according to usage scenarios. In addition, some high-end models have also introduced ultra-wideband (UWB) technology to improve positioning accuracy and achieve a more secure "proximity unlock" function.

[0006] In the existing technology, in order to realize Bluetooth and NFC functions at the same time, vehicles usually use independently deployed Bluetooth controllers and NFC controllers. The two controllers are responsible for the signal reception and processing of the corresponding communication protocols, and are independent of each other in hardware and often installed in different locations (e.g., respectively placed on door handles, rearview mirrors or other areas of the vehicle body). This discrete architecture has the following problems: (1) Increased cost: car manufacturers need to purchase two independent control modules, which leads to an increase in material costs; (2) Large space occupation: the two modules need to reserve installation space in different locations of the vehicle body, which increases the complexity of structural design; (3) High assembly complexity: the two modules need to be wired, installed and debugged separately during the vehicle production process, which prolongs the production line operation time and increases manufacturing and maintenance costs; (4) Low system integration: the dual controller architecture makes it difficult to achieve signal collaborative management and resource sharing, which is not conducive to functional expansion and subsequent upgrades.

[0007] Therefore, there is an urgent need for a dual unlocking signal receiving and triggering module that is more integrated, lower in cost, and easier to install, in order to achieve efficient integration of Bluetooth and NFC functions and meet the needs of smart cars for lightweight, modular, and highly reliable electronic systems.

[0023] This utility model solves the above-mentioned technical problems and also proposes a means of transportation, including the aforementioned dual unlocking signal receiving and triggering module.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) By integrating the NFC antenna and the Bluetooth antenna into the same dual unlock signal receiving and triggering module, a single module can simultaneously have both NFC and Bluetooth functions. At the same time, by integrating the NFC antenna into the NFC antenna board and setting the NFC antenna board and the main control circuit board at intervals, the overall size of the module is effectively controlled and the bulky structure is avoided while realizing the dual-mode communication function.

[0026] (2) By setting the NFC antenna on the side of the NFC antenna board away from the main control circuit board, the electromagnetic interference of electronic components on the main control circuit board to the NFC radio frequency signal can be effectively reduced, thereby improving the stability and recognition sensitivity of NFC communication.

[0027] (3) The NFC antenna is electrically connected to the main control circuit board via a pin block. At the same time, the Bluetooth antenna and signal processing components are integrated inside the module, thereby achieving a high degree of integration of Bluetooth and NFC dual-mode functions. This significantly reduces the number of parts and installation space requirements, and lowers system complexity and manufacturing costs. In addition, the housing integration design improves the structural strength and positional accuracy of the NFC antenna, which is conducive to achieving stable and reliable near-field communication performance.

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] Example 1

[0034] like Figures 1 to 2As shown, this embodiment mainly focuses on the specific structure of the dual unlocking signal receiving and triggering module, and its application in transportation vehicles. The aforementioned transportation vehicles can be automobiles, airplanes, ships, etc. For ease of description, the following embodiment only uses the application of this module in an automobile as an example for detailed explanation.

[0035] A dual unlock signal receiving and triggering module includes: an NFC antenna board 100, a main control circuit board 200, and a pin block 300.

[0036] Specifically, the NFC antenna board 100 serves as the carrier component of the NFC antenna, and its surface can be used to fix the NFC antenna in a flat manner; of course, in another embodiment, the NFC antenna board 100 is made of plastic material, and the NFC antenna is integrated inside it by pre-embedded inserts.

[0037] The main control circuit board 200, serving as the control center of the entire module, is spaced apart from the NFC antenna board 100, forming a gap between them. Preferably, the NFC antenna board 100 and the main control circuit board 200 are arranged substantially parallel to each other. The main control circuit board 200 includes a first mounting area 210 and a second mounting area 220: the first mounting area 210 is located within the gap and is equipped with a Bluetooth antenna; the second mounting area 220 is equipped with electronic components for processing Bluetooth and NFC signals.

[0038] The pin block 300 is disposed within the gap space and connected between the NFC antenna board 100 and the main control circuit board 200. The pin block 300 is used to realize the electrical connection between the NFC antenna, the Bluetooth antenna and electronic components, and to connect the NFC antenna and the Bluetooth antenna to the main control circuit board 200 in a predetermined order through time-division control logic.

[0039] This solution integrates the NFC antenna and Bluetooth antenna into the same dual unlocking signal receiving and triggering module, enabling a single module to simultaneously possess both NFC and Bluetooth functions. Furthermore, by integrating the NFC antenna into the NFC antenna board 100 and spacing the NFC antenna board 100 from the main control circuit board 200, the overall size of the module is effectively controlled, avoiding a bulky structure, while achieving dual-mode communication functionality.

[0040] Furthermore, this solution integrates Bluetooth and NFC functions into the same control module. All operations related to the digital key are processed and decided by a central system, avoiding command conflicts caused by improper coordination between multiple independent controllers. Especially in boundary scenarios such as "the user triggers automatic Bluetooth locking while performing NFC unlocking," the system can accurately determine the operation intent based on preset priority logic and make reasonable and safe responses, thereby significantly improving the reliability of the entire vehicle system and the user experience.

[0041] In this solution, the explanation for command conflicts is as follows: Assume the following scenario: The user has just swiped the car door with their mobile phone's NFC, preparing to unlock the vehicle; however, at the same time, the user's mobile phone is still within Bluetooth signal range, and the system detects that the user has left the vehicle, automatically triggering the locking logic. At this time, the NFC controller believes: "The user is approaching and swiping the card, so the unlocking should be maintained or the unlocking should be executed"; the Bluetooth controller believes: "The user has left the vehicle range, so the locking should be executed".

[0042] Two controllers send opposing commands to the vehicle's main control system (one to unlock, the other to lock), creating a "decision-making conflict." Without a unified arbitration mechanism, the vehicle may fail to lock (a security hazard); repeatedly unlock and unlock (a terrible user experience); or even cause system errors and enter protection mode. This is what is known as a "multi-controller decision-making conflict."

[0043] In distributed systems, different modules often have their own decision-making logic and triggering conditions. When multiple events occur simultaneously, determining whose instruction should be executed first requires a "referee." In the original dual-controller architecture, there was no unified scheduling mechanism; priority logic might be inconsistent or missing; this could easily lead to unpredictable system behavior.

[0044] In this solution, all signals (Bluetooth status, NFC card swipe action, timestamp, user behavior sequence) are processed by the same processor. The system can make comprehensive judgments and arbitrations based on preset strategies (such as "NFC manual operation takes precedence over Bluetooth automatic locking"), avoiding command conflicts and ensuring that actions are unique, safe, and reliable.

[0045] It should be noted that the attached diagram of this solution defines the first mounting area 210 as the left side of the main control circuit board 200 and the second mounting area 220 as the right side of the main control circuit board 200. However, in actual operation, the positions of the first mounting area 210 and the second mounting area 220 can be interchanged.

[0046] It is worth mentioning that the NFC antenna is integrated on the side of the NFC antenna board 100 away from the main control circuit board 200.

[0047] In this design, the NFC antenna is positioned on the side of the NFC antenna board 100 opposite to the main control circuit board 200. This effectively reduces electromagnetic interference from electronic components on the main control circuit board 200 to the NFC radio frequency signal, improving the stability and recognition sensitivity of NFC communication. Simultaneously, this layout facilitates the NFC antenna's proximity to external sensing areas of the vehicle (such as door handle surfaces), optimizing the signal coupling path and increasing the success rate and response speed of user card unlocking.

[0048] Preferably, two pin blocks 300 are provided in the continuous cavity, and the two pin blocks 300 are arranged opposite each other to fix the height distance between the NFC antenna board 100 and the main control circuit board 200.

[0049] The two opposing pin blocks 300 not only achieve electrical connection but also serve as structural support and positioning functions, enabling precise control of the spacing between the NFC antenna board 100 and the main control circuit board 200 to ensure assembly consistency. This design simplifies the need for additional support structures, improves the overall structural stability of the module, prevents loosening of connections due to vibration or impact, and enhances the product's durability and reliability in automotive environments.

[0050] The second mounting area 220 extends to the outside of the continuous cavity and to the side of the main control circuit board 200 away from the NFC antenna board 100.

[0051] By placing the second mounting area 220 on the side of the main control circuit board 200 away from the NFC antenna board 100, the space of the circuit board is fully utilized, which facilitates high-density integration of core electronic components (such as MCU, power management chip, etc.) used to process Bluetooth and NFC signals, thereby helping to reduce the overall size of the dual unlock signal receiving and triggering module.

[0052] This solution also includes a housing 400, which has a receiving cavity inside, and the NFC antenna board 100 and the main control circuit board 200 are both disposed in the receiving cavity.

[0053] By encapsulating the NFC antenna board 100 and the main control circuit board 200 within the housing 400, the mechanical protection of the module is enhanced, effectively preventing damage to the internal circuitry from dust, moisture, and external impacts.

[0054] Example 2

[0055] A dual unlock signal receiving and triggering module includes: a housing, a main control circuit board 200, and a pin block 300.

[0056] Specifically, an NFC antenna is integrated inside the housing; a main control circuit board 200 is disposed inside the housing, and the main control circuit board 200 includes a first mounting area 210 and a second mounting area 220. A Bluetooth antenna is disposed in the first mounting area 210, and electronic components for processing Bluetooth and NFC signals are disposed in the second mounting area 220; a pin block 300 is disposed inside the housing; wherein, the pin block 300 is used to electrically connect the NFC antenna, the Bluetooth antenna, and the electronic components.

[0057] This embodiment shares a similar design concept with Embodiment 1, integrating NFC and Bluetooth functions into a single module to achieve dual-mode signal reception and processing. The difference lies in that this embodiment integrates the NFC antenna directly into the housing, rather than using a separate NFC antenna board 100 for support.

[0058] The NFC antenna is electrically connected to the main control circuit board 200 via pin 300. Simultaneously, a Bluetooth antenna and signal processing components are integrated within the module, achieving a high degree of integration between Bluetooth and NFC dual-mode functionality. Compared to traditional discrete controller solutions, this structure significantly reduces the number of components and installation space requirements, lowering system complexity and manufacturing costs. Furthermore, the integrated housing design enhances the structural strength and positional accuracy of the NFC antenna, contributing to stable and reliable near-field communication performance.

[0059] Furthermore, the first mounting area 210 is located on the side of the main control circuit board 200 facing the NFC antenna, and the projection of the NFC antenna on the first mounting area 210 is staggered with that of the Bluetooth antenna; the second mounting area 220 includes the side of the main control circuit board 200 facing the NFC antenna and the side away from the NFC antenna.

[0060] Preferably, the housing and the NFC antenna are integrally formed by injection molding.

[0061] In summary, this solution provides a highly integrated dual-unlock signal receiving and triggering module. By coordinating the NFC and Bluetooth antennas and integrating them into the same control unit, this module achieves deep integration of NFC near-field communication and Bluetooth contactless unlocking functions. Compared to the traditional discrete architecture using independent controllers, this solution effectively reduces the number of hardware components, lowers system complexity, manufacturing costs, and installation space requirements.

[0062] Furthermore, the pin block 300 enables electrical connection and structural positioning between multiple components, balancing signal transmission reliability and assembly stability; the unified main control circuit processes dual-mode signals, avoiding instruction conflicts caused by judgment logic conflicts between multiple controllers, thus improving system security and response consistency.

[0063] Whether employing a modular design with an independent NFC antenna board 100 or an integrated solution that incorporates the NFC antenna into the housing, both demonstrate significant advancements in structural compactness, functional integration, and engineering feasibility. This module can be widely used in intelligent transportation vehicles such as automobiles, supporting the multimodal unlocking requirements of digital keys.
