[0027] The following is for reference. Figures 1-5 This invention describes a millimeter-wave ranging alarm radar 100 according to an embodiment of the present invention.

[0028] like Figure 1 As shown, this utility model provides a millimeter-wave ranging alarm radar 100 that can be embedded in a vehicle body.

[0029] The millimeter-wave ranging alarm radar 100 includes a housing 1, a patch microstrip antenna, and a control board 3. The housing 1 has a mounting cavity 10 and a first clearance opening 111, which communicates with the mounting cavity 10.

[0030] The patch microstrip antenna array 2 is disposed within the mounting cavity 10 and includes a transmitting antenna array for transmitting electromagnetic wave signals and a receiving antenna array for receiving electromagnetic wave signals. The transmitting antenna array and the receiving antenna array are positioned corresponding to the first clearance opening 111 so that the electromagnetic wave signals can pass through the first clearance opening 111, avoiding interference of the housing 1 with the electromagnetic wave signals, and ensuring that the electromagnetic wave signals of the transmitting antenna array are transmitted to the outside of the mounting cavity 10. The millimeter-wave ranging alarm radar 100 can detect the driving environment more accurately.

[0031] The control board 3 is housed inside the housing 1, and the control board 3 is electrically connected to the patch microstrip antenna array 2.

[0032] Based on the technical solution, the embodiments provided by this utility model have the following advantages: (1) The millimeter-wave ranging alarm radar 100 can be embedded in the vehicle body and emit electromagnetic wave signals to the outside of the vehicle body to detect the vehicle's driving environment. (2) A first clearance opening 111 is provided on the housing 1, and the patch microstrip antenna array 2 is correspondingly set at the first clearance opening 111 to avoid interference of the housing 1 with the electromagnetic wave signal, so as to ensure smooth transmission and reception of the electromagnetic wave signal, thereby enabling the patch microstrip antenna array 2 to detect the driving environment more accurately. Especially when the millimeter-wave ranging alarm radar 100 is applied to large trucks, it can reduce the blind spot of the vehicle and improve reliability and safety.

[0033] In a specific example, the vehicle body has a mounting slot for mounting the millimeter-wave ranging alarm radar 100. The size of the mounting slot must match the size of the housing 1 to ensure that the millimeter-wave ranging alarm radar 100 can be embedded in the vehicle body. The housing 1 is also connected to four lugs 112, each lug 112 having a screw hole. The mounting slot includes a countersunk platform for embedding the lugs 112, the countersunk platform having lug holes. Fasteners pass through the screw holes on the lugs 112 and the lug holes in sequence to fasten the housing 1 to the vehicle body. The screw holes on the lugs 112 and the lug holes on the vehicle body can be 3mm in diameter.

[0034] like Figure 1 and Figure 2 As shown, the first clearance opening 111 is matched in size and shape with the patch microstrip antenna array 2, and the patch microstrip antenna array 2 is completely open to the outside, further improving the accuracy of detection.

[0035] like Figure 3 As shown, the patch microstrip antenna array 2 is higher than the outer surface of the housing 1. Sealant is applied between the edge of the first clearance opening 111 and the patch microstrip antenna array 2, and / or, they are connected by a sealing ring. During the manufacturing process of the millimeter-wave ranging alarm radar 100, the edge of the first clearance opening 111 and the patch microstrip antenna array 2 are sealed to prevent moisture and dust from entering the mounting cavity 10 through the gap.

[0036] like Figure 1As shown, the control board 3 further includes a main control board 32 and a radar signal processing system board 31 electrically connected. The radar signal processing system board 31 is electrically connected to the patch microstrip antenna array 2. The radar signal processing system board 31 is used to convert the received electromagnetic wave signals into electrical signals and transmit them to the main control board 32. The main control board 32 is used to connect to the alarm device. Specifically, the radar signal processing system board 31 mainly uses algorithms to process the received electromagnetic wave signals to determine the target distance, and is also used to control the generation and transmission of electromagnetic wave signals from the patch microstrip antenna array 2. The main control board 32 is used to receive the specific target distance value given by the radar signal processing system board 31, identify interference signals, filter out the correct distance value, and make corresponding alarm judgments in a timely manner. The use of dual boards is to distinguish the functions undertaken by each board, facilitate the separate subsequent update and development of the two functions, reduce the computational pressure on different boards, avoid excessive computational pressure, and improve stability.

[0037] like Figure 1 As shown, the radar signal processing system board 31 and the main control board 32 are further connected by a cable; the radar signal processing system board 31 and the main control board 32 are positioned opposite each other and spaced apart, forming a clearance space between them for the cable to pass through. Communication between the two boards via the cable can reduce electromagnetic interference.

[0038] like Figure 1 As shown, the patch microstrip antenna array 2 is further fixedly connected to the side of the radar signal processing system board 31 that is away from the main control board 32.

[0039] like Figure 1 As shown, furthermore, one side of the radar signal processing system board 31, which holds the patch microstrip antenna array 2, rests against the inner surface of the housing 1 and is coated with an anti-corrosion paint. A small portion of the radar signal processing system board 31 may be exposed; the anti-corrosion paint coating on its surface helps to prevent water, moisture, and salt spray damage. Specifically, the surface of the radar signal processing system board 31 can be coated with conformal coating.

[0040] like Figure 3 As shown, the main control board 32 is further provided with a power supply interface (not shown in the figure). The power supply interface includes a power supply housing and a power supply connector located inside the power supply housing. A second clearance hole 122 is provided on the housing 1, and the power supply housing is located in the second clearance hole 122. Sealant is applied between the power supply housing and the second clearance hole 122. This prevents moisture and dust from entering the mounting cavity 10 through the second clearance hole 122.

[0041] The power supply connections here can be terminal assemblies.

[0042] like Figure 4 and Figure 5 As shown, the main control board 32 further includes a signal output interface 322, which includes a signal output housing 3221 and a signal electrical connector 3222 disposed within the signal output housing 3221. A third clearance hole 123 is provided on the housing 1. The signal output housing 3221 is located within the second clearance hole 122, and sealant is applied between the signal output housing 3221 and the third clearance hole 123. This prevents moisture and dust from entering the mounting cavity 10 through the third clearance hole 123.

[0043] The signal electrical connector 3222 here can be a terminal assembly.

[0044] like Figure 4 and Figure 5 As shown, furthermore, the signal output interface 322 has at least two components, one of which is connected to the audio alarm module on the vehicle, and the other is connected to the display module on the vehicle, providing accurate blind spot warning information to the driver.

[0045] like Figure 1 As shown, the millimeter-wave ranging alarm radar 100 further includes fasteners; the mounting cavity 10 is provided with multiple protruding fastening structures 124; the main control board 32 is provided with fastening holes 321; the fasteners pass through the fastening holes 321 and are fixedly connected to the protruding fastening structures 124, thereby improving the stability and reliability of the internal structure.

[0046] A second aspect of this utility model provides a vehicle, which includes a vehicle body and the aforementioned millimeter-wave ranging and alarm radar 100. The millimeter-wave ranging and alarm radar 100 is embedded in the vehicle body.

[0047] The following is based on Figures 1-5 Let me describe a specific implementation.

[0048] Please see Figures 1-5 The millimeter-wave ranging alarm radar 100 includes a housing 1, which comprises a first housing portion 11 and a second housing portion 12, forming a mounting cavity 10 between the first housing portion 11 and the second housing portion 12. A male stop and a female stop are provided at the connection between the first housing portion 11 and the second housing portion 12. One of the male and female stops is located on the first housing portion 11, and the other is located on the second housing portion 12. The male and female stops cooperate to position the relative positions of the first housing portion 11 and the second housing portion 12, and simultaneously seal the connection between the first housing portion 11 and the second housing portion 12, thus reducing the entry of moisture, dust, and other impurities into the mounting cavity 10 through the connection between the first housing portion 11 and the second housing portion 12.

[0049] The millimeter-wave ranging alarm radar 100 also includes a main control board 32, a radar signal processing system board 31, and a patch microstrip antenna array 2, all housed within the mounting cavity 10. The radar signal processing system board 31 and the patch microstrip antenna array 2 are fixed to the first housing 11, which has a first clearance opening 111 corresponding to the patch radar antenna array. The main control board 32 is fixed to the second housing 12, which has a second clearance hole 122. The power supply interface on the main control board 32 is correspondingly located in the second clearance hole 122 for connecting to an external power source.

[0050] Furthermore, the radar signal processing system board 31 uses a low-power processor, which can significantly reduce power consumption and heat dissipation.

[0051] Furthermore, the second housing 12 is also provided with a third clearance hole 123, and the signal output interface 322 on the main control board 32 is correspondingly located at the third clearance hole 123. A connecting cable is inserted into the corresponding jack to connect the audio alarm module and the display module, providing accurate blind spot warning information for the driver.
