[0001] The present application relates to the technical field of automobile logo, and in particular relates to a car logo flickering car-finding prompting system integrated with a buzzer. BACKGROUND

[0002] Traditional vehicle positioning methods rely on remote key triggering a single buzzer to sound, which is prone to positioning ambiguity and response delay in complex environments. In the prior art, Chinese patent CN223212294U optimizes the installation stability of the siren device through an O-ring sealing structure, but does not involve a collaborative design with visual prompts; the noise monitoring system proposed in Chinese patent CN120609443A can achieve multi-parameter detection, but does not provide a solution for the precise positioning needs of car-finding scenarios.

[0003] The car-finding prompting systems currently available on the market all have the following technical defects:

[0004] 1. Single prompting mode limitation: Traditional solutions only use acoustic or visual single prompting modules, which are easily disturbed in complex environments such as parking lots and at night, making it difficult for users to quickly and accurately locate the vehicle;

[0005] 2. Acoustic and optical interference risks: The use of single-frequency buzzer or fixed-mode LED flickering solutions is prone to frequency overlap or interference with other vehicle prompt signals, causing auditory fatigue or visual confusion;

[0006] 3. Response logic rigidity: Existing systems lack intelligent distance sensing capabilities and multi-modal collaborative response mechanisms, and cannot dynamically adjust the prompt intensity based on the distance between the user and the vehicle, resulting in insufficient close-range warning and excessive long-range guidance;

[0007] 4. Insufficient hardware integration: The acoustic and optical modules are designed separately, occupying a large amount of vehicle space and having poor waterproof sealing performance, making it difficult to meet the long-term stable use requirements of the vehicle environment. SUMMARY

[0035] Reference Figures 1-6As shown, the embodiment provides a car logo flickering prompt system integrated with a buzzer, which comprises a visual module, an acoustic module, and a control unit; the visual module is used for realizing multi-mode flickering (such as fast flashing / slow flashing / pulse) of the car logo, and the visual module is embedded with a LED lamp group of the car logo font; the acoustic module is used for adjusting the sound pressure level according to the distance (high frequency warning at a short distance and low frequency guiding at a long distance), and the acoustic module is embedded with a layered array of buzzers; the control unit is used for realizing a dual mode of remote control triggering and automatic response, and the control unit is integrated with a distance sensor and a wireless receiver. The LED lamp group of the car logo font is a waterproof LED lamp strip, which is embedded in the car logo, and the waterproof LED lamp strip shares a sealed shell with the buzzer, and the sealed shell seals the LED lamp strip and the buzzer to prevent water from entering.

[0036] Further, the control unit in the embodiment receives a car search remote control key of a user's car key, controls the visual module to flicker the LED light, and controls the acoustic module to start the buzzer and gradually enhance the sound if the control unit does not receive a stop signal of the car key within a set time.

[0037] Further, the layered array of buzzers in the embodiment is composed of a plurality of up-and-down arranged frequency division buzzers, which are used for high frequency warning at a short distance and low frequency guiding at a long distance.

[0038] Further, the waterproof LED lamp strip in the embodiment is composed of a plurality of flexible LED lamps, which are attached to the curved side wall of the car logo.

[0039] Further, the acoustic module in the embodiment is provided with a buzzer module connected with the control unit through a wireless receiving module, which is used for remote control triggering and automatic response of the buzzer.

[0040] Further, the sealed shell in the embodiment is composed of an upper shell, a lower shell, and a sealing rubber ring, the sealing rubber ring is arranged at a connecting gap between the upper shell and the lower shell, the material of the sealing rubber ring is nitrile rubber or fluororubber, and the installation mode of the sealing rubber ring is that the initial compression rate is 15%-30% to ensure the static sealing reliability.

[0041] Further, the layered array of buzzers in the embodiment is used for receiving a positioning distance signal of the control unit, and the buzzer dynamically adjusts the buzzer frequency and the sound size according to the positioning distance signal.

[0042] Further, the distance sensor in the embodiment is used for detecting the distance between the user and the vehicle to trigger the sound and light output, and the wireless receiver is used for supporting Bluetooth or radio frequency signal receiving and being compatible with the existing car electronic system.

[0043] Furthermore, in this embodiment, multiple flexible LED lights are evenly distributed on the sidewalls surrounding the car logo.

[0044] Furthermore, the car icon flashing vehicle location prompt system in this embodiment is controlled as follows:

[0045] 1. Visual priority response mechanism

[0046] Once the system is activated, the LED lights will start flashing immediately (the original parallel triggering logic is canceled). Different flashing modes will be output according to the distance, forming a progressive prompting strategy of "visual first, then acoustic".

[0047] 2. Dynamic sound intensity enhancement algorithm,

[0048] After the buzzer is activated, a stepped enhancement strategy is adopted:

[0049] a. Standardize the upper limit of sound intensity;

[0050] The maximum sound intensity of buzzers at all distance levels is limited to 80 dB, which complies with the noise limit requirements for vehicle-mounted acoustic equipment in GB / T 28046.3-2011 "Environmental conditions and tests for electrical and electronic equipment of road vehicles - Part 3: Mechanical load".

[0051] b. Gradual enhancement and rhythm adjustment;

[0052] The time required for the initial sound intensity enhancement step size and enhancement interval to reach 80dB within the distance range;

[0053] >10 meters 30dB +10dB 3 seconds 15 seconds (5 steps);

[0054] 5-10 meters 45dB +15dB 2 seconds 4 seconds (3 steps);

[0055] <5 meters 60dB +20dB 1 second 1 second (1 step);

[0056] Safety design considerations;

[0057] The close-range mode can rapidly increase the warning level from 60dB to 80dB in just 1 second, ensuring the warning effect in emergency situations.

[0058] The long-distance mode employs a slow enhancement strategy to avoid noise pollution to the surrounding environment;

[0059] An 80dB sound pressure level is equivalent to the level of urban traffic noise, which can ensure visibility in parking lot environments while preventing hearing damage.

[0060] It avoids sudden high-decibel stimulation at close range while ensuring the effectiveness of long-distance cues;

[0061] 3. Closed-loop feedback optimization;

[0062] During the audio-visual coordination phase, distance changes and user responses are continuously monitored to achieve a complete closed loop of "visual guidance → acoustic enhancement → collaborative positioning → hibernation".

[0063] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention 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 present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
