Description

Technical Field

[0001] The utility model relates to the technical field of automotive antennas, and particularly relates to an automotive antenna module capable of actively triggering an alarm prompt function. Background Art

[0002] Currently, cars have become the most commonly used means of transportation for people's daily travel. The automotive antenna module (usually located on the roof, commonly known as the shark fin) is an important component of a car. The functions of the automotive antenna module (shark fin) for a car are mainly reflected in the following aspects:

[0003] 1. Receiving or enhancing received signals: The shark fin antenna can receive or enhance external signals, including FM broadcasts, GPS signals, and GSM signals, etc., to facilitate the normal use of wireless transmission devices such as navigation systems and in-vehicle phones in the car;

[0004] 2. Reducing wind resistance and wind noise: According to the principle of aerodynamics, the shark fin antenna can reduce the eddy current at the top of the vehicle body to a certain extent when driving at high speed, thereby helping the vehicle reduce wind resistance and wind noise and improving the driving smoothness and quietness;

[0005] 3. Enhancing safety and aesthetics: The shark fin antenna adopts the latest modern electronic technology, integrates multiple automotive electronic functions, improves the safety and convenience of the car. At the same time, its unique design also plays a role in beautifying the vehicle model, making the appearance of the car more fashionable.

[0006] 4. Convenient to use: Compared with traditional antennas, when the car is automatically washed or enters a place with limited space, the car owner does not need to remove the antenna, saving time and effort.

[0007] Generally speaking, the functions of the automotive antenna (shark fin) for a car are mainly reflected in improving signal reception ability, reducing wind resistance and wind noise, neutralizing static electricity in the car, enhancing safety and aesthetics, and being convenient to use, etc. These functions make the automotive antenna an indispensable part of modern cars. Generally, it mainly completes the antenna functions of communication and FM radio, etc.

[0008] Since the automotive antenna is located at the top of the car and is visually obvious, it is very suitable for giving an alarm when an emergency occurs in the car.

[0009] The "Vehicle Status Lighting Prompt System and Its Control Method" with the application number 202410317703.0 discloses a vehicle status lighting prompt system and its control method, including a three-section integrated indicator light, an indicator light controller, an angle sensor, an acceleration signal sensor, and an SOS alarm switch; the indicator light controller determines the current driving state or fault state of the vehicle based on the detection signals of the angle sensor and the acceleration signal sensor, as well as the start signals of the SOS alarm switch, vehicle gear information, and hazard warning light switch, and controls the three-section integrated indicator light to enter the corresponding lighting prompt mode for lighting display; the three-section integrated indicator light is installed at the position of the shark fin antenna on the top of the vehicle and is powered by a battery. It includes three sections of lighting groups, and each lighting group includes light sources of four colors. The light sources of each lighting group are turned on according to the control signal of the indicator light controller to achieve the lighting display of different lighting prompt modes, which is used to display different states of the vehicle. However, this patent is only obvious at night, and its effect is poor in bad weather and bright daytime. There may also be problems such as aging and lighting failure caused by impact.

[0010] The "Vehicle Emergency Rescue Alarm Device" with the application number 201320181060.9 discloses a vehicle emergency rescue alarm device, including a housing. A connecting device is fixedly connected to the bottom of the housing. A compressed gas cylinder, a solenoid valve, a check valve, and a balloon are sequentially connected and communicated inside the housing. A baffle is arranged in the middle of the housing, and a spring is arranged between the baffle and the balloon. The solenoid valve is connected to a power supply through a wire, and the power supply is also connected to a triggering device through a signal wire. By opening the solenoid valve through an induction device to inflate the balloon, and at the same time ejecting a powder box to spread powder, the position where the vehicle enters the water can be determined in time and smoke is emitted to play an alarm role, so as to attract the attention of others and enable them to be rescued in time. However, the application scenario of this patent is relatively limited, and it is triggered passively and cannot be triggered actively in scenarios where active triggering is required, bringing a not-so-good user experience to people.
