[0003] By installing millimeter-wave radar on the vehicle, all-round detection and early warning around the vehicle can be achieved. Because it uses high-frequency millimeter-wave detection, it overcomes the characteristics of ultrasonic waves such as short range and unstable effect in harsh environments. It has a good application effect in special vehicles, engineering vehicles, port terminal operation vehicles, overhead cranes and other large machinery industries.

In addition, high temperature can easily cause damage to the radar, shortening the service life of the millimeter-wave radar and having poor protection. In view of the above problems, a heat dissipation millimeter-wave radar is proposed. Utility Model Content

A guide component is arranged between the lower shell 101 and the upper shell 103. The lower shell 101 and the upper shell 103 are connected by a fastening component. The peripheral outer walls of the lower shell 101 and the upper shell 103 are both provided with a plurality of heat dissipation fins 106. The millimeter-wave radar body 1 is installed on the bottom plate 2 through a buffer component. An arc seat 7 is fixedly installed on the top of the bottom plate 2. A mounting plate 8 is fixedly installed on the peripheral inner wall of the arc seat 7. A mounting plate 9 is fixedly installed on the peripheral inner wall of the mounting plate 8. A heat dissipation fan 10 is arranged on the side of the mounting plate 9. An air inlet pipe 11 is connected to the end of the mounting plate 8. An expansion suction cup 12 is arranged at the other end of the air inlet pipe 11.

[0024] With the above structure, when in use, when the vehicle is moving, the air is blown into the air inlet pipe 11 through the expansion suction cup 12 and drives the cooling fan 10 to rotate, thereby driving the cooling fan 10 to blow cold air to the millimeter-wave radar body 1. Since a narrow air duct is formed between the multiple cooling fins 106 arranged on the outer walls of the lower shell 101 and the upper shell 103, the heat can be quickly taken away when the cold air blows through, thereby achieving a heat dissipation effect, preventing the millimeter-wave radar 1 from malfunctioning due to high temperature during use, and thereby increasing the service life of the millimeter-wave radar body 1.

[0025] like Figure 2 As shown, the guide assembly includes two guide plates 104, and the two guide plates 104 are fixedly installed at the bottom of the upper shell 103. Two guide grooves are opened on the top of the lower shell 101, and the two guide plates 104 are respectively adapted to the two guide grooves. The advantage of such an arrangement is that the upper shell 103 and the lower shell 101 can be quickly installed through the arrangement of the two guide plates 104 and the two guide grooves, and the guiding performance is better.

[0026] Specifically, when the upper shell 103 and the lower shell 101 are installed, they can be quickly positioned through the guiding functions of the two guide plates 104 and the two guide grooves, which is convenient for the staff to install.

The advantage of such a setting is that the buffering function of the millimeter-wave radar body 1 can be realized through the setting of the rectangular plate 3 and the two fixed shafts 4, thereby improving the protection function of the millimeter-wave radar body 1.

[0030] Specifically, when the vehicle is bumpy during driving, the rectangular plate 3 is slidably mounted on the two fixed shafts 4 to prevent the millimeter-wave radar body 1 from colliding with the bottom plate 2 and causing damage to the millimeter-wave radar body 1 .

The advantage of this arrangement is that through the arrangement of the two buffer springs 6, the buffering function of the rectangular plate 3 can be achieved through its elastic action.

[0032] Specifically, when the vehicle is bumpy, the rectangular plate 3 will slide along the fixed axis 4, and when the rectangular plate 3 moves downward, it will squeeze the two buffer springs 6, thereby achieving a buffering effect. Through the elastic action of the two buffer springs 6, the rectangular plate 3 can be driven to reset, and the protection is better.

[0033] like Figure 4 As shown, the limiting unit includes a limiting plate 5, which is fixedly installed on the top end of the fixed shaft 4, and an elastic pad is arranged at the bottom end of the limiting plate 5. The advantage of such arrangement is that, through the arrangement of the limiting plate 5, the limiting function of the rectangular plate 3 can be realized to prevent the rectangular plate 3 from sliding out of the two fixed shafts 4.

[0034] Specifically, when the rectangular plate 3 slides along the fixed shaft 4, it can be limited by the limiting plate 3 to prevent it from falling off, and the provision of the elastic pad can provide a protective function for the rectangular plate 3.
