DETAILED DESCRIPTION

[0045] like Figure 1-9As shown, the radar base assembly of this embodiment includes a frame assembly 100, the bottom of which is connected to the foundation, and the foundation part is a conventional method; an adjusting connecting rod part 101 is provided on the frame assembly 100, so as to realize the swing of the radar; an adjusting swinging part 102 is provided on the adjusting connecting rod part 101, so as to realize the radar protruding outward or being received at an edge inward;

[0046] The adjusting link part 101 is a four-link mechanism, which is simplified in the figure, and bearings and fasteners are omitted.

[0047] A radar assembly 2 is provided on the adjusting swing portion 102 for conducting reconnaissance scanning.

[0048] As a specific description, the adjusting link part 101 includes a main swing rod A103 and a secondary swing rod B104 whose lower ends are respectively hingedly mounted on the frame assembly 100; a connecting rod C105 is hingedly mounted between the upper ends of the main swing rod A103 and the upper ends of the secondary swing rod B104.

[0049] There are two main swing rods A103 arranged in parallel, two auxiliary swing rods B104 arranged in parallel, and two connecting rods C105 arranged in parallel.

[0050] Two connecting rods C105 are arranged between the two main swing rods A103;

[0051] Two connecting rods C105 are arranged between the two auxiliary swing rods B104; thereby achieving stable support.

[0052] In order to achieve the change of driving mode, a driven drive shaft 106 and a swing gear shaft 110 are respectively provided on the frame assembly 100; the driven drive shaft 106 and the active drive shaft 107 are respectively connected to the corresponding motors through their respective corresponding clutch transmissions; the motor is on the frame assembly 100; thereby achieving driving.

[0053] The root of the driven drive shaft 106 is key-connected to the auxiliary swing rod B104; the root of the main swing rod A103 is key-connected to the active drive shaft 107; the key is preferably a spline type. It should be noted that it can be a fixed key or a sliding key and a matching self-locking positioning component, using conventional parts such as clutches, brakes, positioning blocks or limit supports.

[0054] In order to realize the swing control, a swing gear shaft 110 is hinged between the heads of the two main swing rods A103;

[0055] In order to achieve power transmission, a plurality of intermediate wheel assemblies 109 are provided on the main swing rod A103; of course, a chain can be used instead.

[0056] The active drive shaft 107 is provided with a sliding gear A108 or other clutch control methods;

[0057] As a specific description, the sliding gear A108 is transmission-connected to the swing gear shaft 110 through a plurality of intermediate gear assemblies 109;

[0058] The swing gear shaft 110 is key-connected to the adjustment swing portion 102 .

[0059] As an example, but not limited to this structure, a fork assembly is provided on the frame assembly 100 .

[0060] The fork assembly includes a first driving rod 114 disposed on the frame assembly 100 and a second driving rod 115 connected to the first driving rod 114 in a direction-changing manner;

[0061] A shift fork portion 116 is provided at the end of the second driving rod 115 for shifting the sliding gear A 108 to engage with or disengage from the corresponding intermediate gear assembly 109 .

[0062] In order to realize the longitudinal movement of the radar, increase the detection distance, and form an ingenious combination of relative coordinates and polar coordinates, the adjustment swing part 102 includes a swing frame group 111 connected to the swing gear shaft 110; a longitudinal guide groove 112 and a longitudinal driving rod 113 are provided on the swing frame group 111.

[0063] The radar assembly 2 is disposed in the longitudinal guide groove 112 and connected to the longitudinal driving rod 113 .

[0064] The rack assembly 100 is arranged in the mountain;

[0065] When in operation, the radar assembly 2 is located above the adjustment swing portion 102;

[0066] When converged, the radar assembly 2 is located above or below the adjustment swing portion 102 .

[0067] like Figure 1-9 ,The radar base operation process of this embodiment includes working steps;

[0068] In the working steps, the mountain gate is opened. First, the adjusting link part 101 is started to make a positive parallelogram motion to expose the head end of the main swing rod A103 from the mountain gate; then, an anti-parallelogram motion is made around the adjusting link part 101, so that the main swing rod A103 continues to swing upward and protrude to the set position; thereby saving space and realizing the detection of the radar.

[0069] When performing a positive parallelogram motion, the driven drive shaft 106 is connected to the motor, and the active drive shaft 107 is connected to the motor;

[0070] When performing anti-parallelogram motion, the driven drive shaft 106 is separated from the motor, and the active drive shaft 107 is connected to the motor.

[0071] First, the active drive shaft 107 drives the two main swing rods A103 to swing to the set angle, and then drives the fork part 116 through the first drive rod 114 and the second drive rod 115, so that the sliding gear A108 is engaged with the corresponding intermediate wheel assembly 109; secondly, when the head end of the main swing rod A103 is exposed from the mountain gate, the swing gear shaft 110 drives the swing frame assembly 111 to swing forward; thirdly, the radar assembly 2 moves forward along the longitudinal guide groove 112 through the longitudinal drive rod 113, thereby realizing the ingenious movement of the radar.

[0072] After the working step, there is a convergence step; the convergence step is opposite to the working step, so as to collect the antenna to the edge of the mountain cavity.

[0073] The working steps are performed with the help of radar base components.

[0074] When the radar assembly 2 needs to be replaced, the radar assembly 2 is separated from the longitudinal guide groove 112 and the longitudinal driving rod 113 for disassembly and assembly, thereby realizing a simple split modular setting.

[0075] The present invention supports the whole through the frame assembly 100, and cleverly adjusts the connecting rod part 101 to cleverly design, and utilizes the smooth swing of the regular parallelogram in the mountain. When the radar component 2 is swung out, the anti-parallelogram is used to achieve the radar component 2 to reach the set position. Compared with a single regular parallelogram mechanism, it can achieve a smoother protrusion of the radar component 2 to avoid getting stuck. Compared with the anti-parallelogram mechanism, it can achieve the upward swing and contraction of the radar component 2 in the mountain, save space, and achieve a superposition effect. By coordinating and adjusting the swing part 102, polar coordinates are established to further increase the protrusion distance of the radar component 2.

[0076] As a specific structure, it realizes a connecting rod mechanism through a main swing rod A103, a secondary swing rod B104, and a connecting rod C105, realizes a positive parallelogram and an anti-parallelogram mechanism through a driven drive shaft 106 and an active drive shaft 107 to realize the detection and convergence of the radar, and in the convergence process, realizes that the inner cavity space of the mountain is occupied as little as possible, and the sliding gear A108 can be three gears or two gears, and the transmission is realized through the intermediate wheel assembly 109 and the chain, belt and gear. The swing gear shaft 110 realizes the swing of the swing frame group 111, and the radar movement adjustment is realized through the longitudinal guide groove 112 and the longitudinal drive rod 113. The fork part 116 is realized through the first drive rod 114 and the second drive rod 115, and the movement of the sliding gear A108 is realized to achieve clutch.
