Description

Technical Field

[0001] The utility model relates to the technical field of intelligent vehicle testing, and in particular to a base station simulation antenna control device for electromagnetic compatibility testing of an intelligent network-connected vehicle. Background Art

[0002] Intelligent Connected Vehicle (ICV) refers to the organic combination of Internet of Vehicles and smart cars, and is a new generation of cars that can eventually replace human operation. Intelligent connected vehicles are equipped with advanced on-board sensors, controllers, actuators and other devices, integrating modern communication and network technologies to achieve intelligent information exchange and sharing between vehicles and people, vehicles, roads, and backgrounds, and are safe, comfortable, energy-saving, and efficient.

[0003] Two sets of antennas are often required in the testing of intelligent connected vehicles, one of which is a satellite antenna for navigation, and the other is an antenna for base station simulation. In the network function test, most tests currently use a simulated antenna static method or establish a darkroom top rail to move the antenna during the test. Although the layout of vehicle-mounted antennas is mostly concentrated in the vehicle-mounted electrical components, namely the vehicle-mounted T-BOX, the metal interference of the vehicle body makes the directional pattern of the vehicle-mounted antenna not uniform in all directions, and this change will be aggravated as the vehicle-mounted antenna begins to be laid out in other positions of the vehicle body. Therefore, when simulating the communication of vehicle road driving in the darkroom, the relative angle rotation of the vehicle and the base station must be considered. Since the position and angle of the vehicle and the base station change continuously as the vehicle drives, a device simulation is required to realize the real-time position of the vehicle on the driving road and the position and angle changes of the base station. Utility Model Content

[0004] In view of the problems of unreasonable static antenna testing in the above-mentioned prior art, the high cost of moving the antenna based on the top rail of the darkroom, and the inability to achieve real-time position angle changes of the antenna during the test, the utility model provides a base station simulation antenna control device for electromagnetic compatibility testing of intelligent networked vehicles. To achieve the above-mentioned purpose, the utility model provides the following technical solutions:

[0006] Furthermore, the fixing assembly includes a flange base and a threaded rod; the flange base is fixedly connected to the end of the posture adjustment assembly by a fixing bolt; two connecting frames are fixed on the flange base, and the threaded rod is supported on through holes provided on the two connecting frames; the threaded rod is equipped with a nut, and the threaded rod is used to connect the antenna.

[0007] Furthermore, the flange base and the two connecting frames are integrally formed.

[0008] Furthermore, the posture adjustment component is a three-axis robotic arm; the bottom of the robotic arm is fixed to the base by bolts.

[0009] Furthermore, the base is a square base; the base includes a base frame and a plurality of panels arranged on the base frame, and the plurality of panels are surrounded to form a cavity.

[0010] Furthermore, the base frame and the panel are both made of metal.

[0011] Furthermore, a circular hole is provided on the top surface of the base for the power line and the control line of the posture adjustment component to pass through.

[0012] Furthermore, a fiber optic interface and a power interface are provided on a panel on one side of the base.

[0013] Furthermore, the moving mechanism includes at least three roller assemblies located at the edge of the bottom surface of the base; and the roller assemblies are each provided with a brake mechanism, and the brake mechanism is used to prevent the roller assemblies from rolling.
