Technical Field

[0001] This utility model relates to the field of radar technology, specifically to a vehicle-mountable millimeter-wave radar. Background Technology

[0002] Millimeter-wave radar is a type of radar that operates in the millimeter-wave band. Compared with centimeter-wave seekers, millimeter-wave seekers are smaller, lighter, and have higher spatial resolution. Compared with optical seekers such as infrared, laser, and television seekers, millimeter-wave seekers have a stronger ability to penetrate fog, smoke, and dust, and are available in all weather and all time conditions.

[0003] Vehicle-mounted millimeter-wave radar is crucial for the use of autonomous driving functions in vehicles. However, currently common vehicle-mounted millimeter-wave radars are difficult to disassemble quickly during installation, which affects the inspection and replacement of vehicle-mounted millimeter-wave radars. In addition, some vehicle-mounted millimeter-wave radars have poor anti-interference performance during use, which affects the sensitivity of vehicle-mounted millimeter-wave radars.

[0004] There is an urgent need for a vehicle-mountable millimeter-wave radar to address the technical shortcomings mentioned above. Utility Model Content

This structure realizes the function of enhancing anti-interference effect.

[0015] (3) By setting an outer shell, a breathable and waterproof membrane, vent holes, connecting blocks, connecting slots and mounting bolts, the vent holes at the bottom of the outer shell facilitate the air to circulate inside the outer shell and carry away the heat inside the outer shell.

[0025] The mounting block 11 is convex in shape. The mounting block 11 is embedded in the reserved groove 16 and is limited by the limiting baffle 17. The mounting base 1 has four sets of mounting holes 12 inside.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, during installation, the mounting base 1 needs to be installed in the vehicle mounting area with bolts first. The housing 3 of the millimeter-wave radar can be installed on the mounting base 1. The connecting block 13 at the bottom of the housing 3 can be directly inserted into the reserved slot 16 of the connecting seat 2. Then, the limiting baffle 17 is rotated to press it on the connecting block 13 to achieve limiting and fixing. When disassembling the millimeter-wave radar, it is only necessary to rotate the limiting baffle 17 to move the connecting block 13 out of the reserved slot 16.

[0027] The breathable and waterproof membrane 4 is fixedly connected to both sides with connecting clips 13, and the inside of the outer shell 3 is fixedly connected to both sides with connecting slots 14.
