[0002] Millimeter-wave radar is a radar system that uses the millimeter-wave frequency band (usually 30 GHz to 300 GHz, with a wavelength between 1 mm and 10 mm). Due to its short wavelength, millimeter-wave radar has the advantages of high resolution and high precision. The working principle of millimeter-wave radar is similar to that of other types of radar. It transmits electromagnetic waves and receives the signals reflected from the target. By analyzing these reflected signals, the system can obtain the target's distance, speed, direction, and other characteristics.

[0003] Millimeter-wave radar can be applied in the field of drones and can be used in the navigation and obstacle avoidance systems of drones to ensure efficient flight in complex environments. When flying, drones are easily affected by uncertain weather conditions. When encountering sudden rainy days, the erosion of rainwater can easily cause damage to the millimeter-wave radar, thereby affecting the normal flight of the drone.

In addition, some aspects disclosed in the present invention can be used alone or in any appropriate combination with other aspects disclosed in the present invention.

[0023] Example 1

[0024] like Figure 1-4 As shown, this is the first embodiment of the utility model, which provides a sealed all-weather millimeter wave radar, including:

[0025] The main unit 1 includes a fixing plate 101, a fixing plate 102 is provided on the front of the fixing plate 101, a protective ring 104 is fixedly connected to the front of the fixing plate 102, a millimeter-wave radar body 103 is fixedly connected to the front of the fixing plate 101 and located in the inner cavity of the protective ring 104, a protective cover 105 is provided on the front of the fixing plate 102, and a cover plate 106 is fixedly connected to the front of the protective cover 105;

[0026] The mounting unit 2 includes a mounting frame 201, which is located on both sides of the front of the fixing plate 101 and is fixedly connected to the fixing plate 101. Both sides of the fixing plate 102 are fixedly connected with mounting plates 202. One side of the mounting plate 202 extends to the inner cavity of the mounting frame 201 and is detachably connected to the inner cavity of the mounting plate 202.

[0027] like Figure 1-4As shown, the fixing plate 101 is used to install the fixing plate 102. Since the fixing plate 101 is fixed to the surface of the drone, the fixing plate 102 can be installed on the surface of the drone so that it can follow the flight of the drone. The fixing plate 102 is used to fix the millimeter-wave radar body 103. The protective ring 104, the protective cover 105 and the cover plate 106 cooperate to provide a closed placement space for the millimeter-wave radar body 103, thereby preventing the millimeter-wave radar body 103 from being soaked by rain during flight and affecting its normal use. The mounting frame 201 and the mounting plate 202 play the role of installing the fixing plate 102 on the surface of the fixing plate 101. Since it is easy to install and disassemble, it is easy to perform regular inspections on it, which provides convenience for its maintenance work.

[0028] Example 2

[0029] Reference Figure 2 and 4 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0030] In this embodiment, the surface of the protective ring 104 is provided with an external thread, the inner cavity of the protective cover 105 is provided with an internal thread, the front end of the protective ring 104 extends to the inner cavity of the protective cover 105 and is threadedly connected to the inner cavity of the protective cover 105, and the cover plate 106 is made of thin plastic.

[0031] A vent 107 is provided at the bottom of the inner cavity of the protective cover 105 , and a dustproof net is fixedly connected to the inner cavity of the vent 107 .

[0032] like Figure 2 and 4 As shown, since the protective ring 104 is threadedly connected to the protective cover 105, the protective cover 105 can be removed by twisting it. Since the cover 106 is made of thin plastic, the plastic material has little attenuation on the millimeter wave radar body 103, so the millimeter wave radar body 103 can effectively penetrate.

[0033] Example 3

[0034] Reference Figure 2 , which is the third embodiment of the present utility model, is based on the first two embodiments.

[0035] In this embodiment, a hollow block 203 is fixedly connected to the front of the mounting frame 201, a positioning hole 204 is provided on the front of the mounting plate 202, and a movable plate 205 is movably connected to the inner cavity of the hollow block 203. The rear end of the movable plate 205 extends to the inner cavity of the positioning hole 204 and engages with the inner cavity of the positioning hole 204.

[0036] A pull rod 206 is provided on the front of the hollow block 203 , the rear end of the pull rod 206 passes through the inner cavity of the hollow block 203 and is fixedly connected to an anti-slip block 207 , and the front end of the movable piece 205 is fixedly connected to the back of the anti-slip block 207 .

[0037] A compression spring 208 is provided on the surface of the pull rod 206 and located in the inner cavity of the hollow block 203. The front end of the compression spring 208 is fixedly connected to the inner wall of the hollow block 203, and the rear end of the compression spring 208 is fixedly connected to the front of the anti-slip block 207.

[0038] like Figure 2 As shown, by pulling the pull rod 206, the anti-slip block 207 can be used to drive the movable piece 205 to move. When the anti-slip block 207 moves, it can squeeze the compression spring 208 and cause the compression spring 208 to deform until the movable piece 205 moves out from the inside of the positioning hole 204. After moving out, the positioning effect on the mounting piece 202 disappears. At this time, the fixing plate 102 can be removed from the front of the fixing piece 101 by pulling up, so as to perform regular maintenance on the millimeter wave radar body 103.

[0039] When in use, the protective cover 105 and the cover plate 106 cooperate to provide a closed placement space for the millimeter wave radar body 103, thereby preventing the millimeter wave radar body 103 from being wetted by rain during flight and affecting its normal use. Since the protective ring 104 is threadedly connected to the protective cover 105, the protective cover 105 can be disassembled by twisting it. Since the cover plate 106 is made of thin plastic, the plastic material has little attenuation on the millimeter wave radar body 103, so the millimeter wave radar body 103 can effectively penetrate it. When disassembling and overhauling, first pull the pull rod 206 forward, and by pulling the pull rod 206, the movable piece 205 can be moved in cooperation with the anti-slip block 207. When the anti-slip block 207 moves, it can squeeze the compression spring 208 and cause the compression spring 208 to deform until the movable piece 205 moves out from the inside of the positioning hole 204. After moving out, the positioning effect on the mounting piece 202 disappears. At this time, the fixing plate 102 can be removed from the front of the fixing piece 101 by pulling up, and then the protective cover 105 can be removed by twisting it, and the millimeter wave radar body 103 can be regularly overhauled.

[0040] The standard parts used in this application document can all be purchased from the market, and can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field. In addition, this application is mainly used to protect mechanical devices, so this application no longer explains the control method and circuit connection in detail.
