Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the priority of Taiwanese patent application No. 113141904, filed on November 1, 2024, which is incorporated herewith by reference. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to a radar device, and more particularly, to an automotive modular radar device able to isolate and exclude external moisture and dust. 2. The Prior Arts Automotive Radar is a sensing technology applied to vehicles, mainly used to detect the surrounding environment to enhance the safety and autonomous driving capabilities of the vehicle. Automotive radar emits electromagnetic waves through the antenna and receives reflected signals to measure the distance, speed and direction of the target object. It has strong anti-interference capability and is suitable for operating in various weather and lighting conditions. The functions of automotive radar include adaptive cruise control, blind spot detection, emergency braking assistance, lane keeping assistance and parking assistance, etc. The adaptive cruise control function can help the vehicle maintain a safe distance from the vehicle in front at different speeds and achieve automatic acceleration or deceleration. The blind spot detection feature detects blind spots on the sides or rear of the vehicle and alerts the driver to potential hazards. The emergency brake assist function can detect objects ahead and actively brake when a collision is imminent, reducing the risk of an accident. The lane keeping assistance function can combine with the image capture unit to detect the vehicle's driving trajectory and keep the vehicle driving in the lane. Parking assistance feature helps drivers park safely in tight parking lots or garages. The types of automotive radar include short-range radar, mid-range radar and long-range radar. Short-range radar is mainly used for functions such as blind spot detection, vehicle surrounding monitoring, and parking assistance. Mid-range radar is commonly used for forward and rearward vehicle detection, such as adaptive cruise control and collision prevention systems. Long-range radar is responsible for detection at longer distances and is often used in automatic cruise control systems on highways. However, the conventional automotive radar is usually installed directly on the vehicle, and the angle is fixed and cannot be changed. As a result, the range of the field-of-view (FOV) of the conventional automotive radar is fixed and is not adjustable. Furthermore, the waterproof and dustproof effects of conventional automotive radars are poor and cannot meet the standards of international protection level certification. In addition, each position of the vehicle can only be installed with one vehicle radar, instead of multiple vehicle radars. As a result, each position of the vehicle can only rely on the FOV of one vehicle radar for detection, and the detection range is quite restricted and prone to dead ends. In addition, the conventional vehicle radar can only detect the presence or absence of an object, but cannot know what the object actually is. SUMMARY OF THE INVENTION A primary objective of the present invention is to provide an automotive modular radar device, which can adjust the angle of the radar module by replacing the bracket module. Another objective of the present invention is to provide an automotive modular radar device that can provide good waterproof and dustproof effects. Another objective of the present invention is to provide an automotive modular radar device with an expanded detection range. Yet another objective of the present invention is to provide an automotive modular radar device that can capture actual images of objects detected by the radar. In order to achieve the aforementioned objectives, the present invention provides an automotive modular radar device to be installed on a vehicle. The automotive modular radar device comprises a bracket module and a radar module; the bracket module comprises a bracket and the bracket comprises a connected plate and a fixed plate; wherein the connected plate is to be fixed to the vehicle; the fixed plate has a bottom edge and one side, an angle is formed between the bottom edge and the side edge of the fixed plate, and the angle is greater than 0 degrees and less than 90 degrees, and the bottom edge of the fixed plate is disposed on the connected plate; the radar module comprises a radar, and the radar comprises a casing, a circuit board, an antenna module, and a processing unit; wherein one side of the casing is fixed to the side of the fixed plate, the circuit board is disposed inside the casing, the antenna module is disposed on the circuit board, the processing unit is disposed on the circuit board and is electrically connected to the antenna module; the casing covers the circuit board, the antenna module, and the processing unit to isolate and exclude external moisture and dust.
