Description

Technical Field

[0001] The utility model belongs to the field of testing equipment, and particularly relates to a Beidou dark box test turntable with a telescopic arm structure. Background Art

[0002] The Beidou dark box test turntable is a professional equipment specifically used for testing equipment related to the Beidou satellite navigation system. The current Beidou dark box test turntable has the following disadvantages without a telescopic arm structure: First, due to the lack of telescopic function, the test turntable is greatly limited in adjusting the distance between the device under test and the signal source or other test components, and it cannot flexibly simulate the signal transmission situation at different distances. The reason for this disadvantage is that the requirement of flexible distance adjustment was not considered in the design. The conventional coping method is to use fixed adapters with different lengths to change the distance, but the disadvantage of this method is that the adapters need to be frequently replaced, the operation is cumbersome and time-consuming, and the number and specifications of the adapters are limited, and the distance cannot be adjusted continuously and finely. Therefore, a new structure is needed to solve the above technical problems. Summary of the Utility Model

A robotic claw 250 is installed at one end of the third robotic arm 240 away from the second robotic arm 230.

[0021] Please refer to Figures 1 to 3 , as the first embodiment of the present utility model: the box door 110 is damped and hinged to the right edge of the upper surface of the box body 100. An electromagnetic generator 130 is installed at the center position of the upper surface of the box door 110. An electromagnetic generating end 131 penetrates through the box door 110 and is installed on the lower surface of the electromagnetic generator 130. The box door 110 is fixed to the box body 100 through a fixing member 111;

[0022] The cable interface 101 is installed at the lower right edge of the outer surface of the box body 100. Electromagnetic shielding layers 120 are integrally installed on the upper, lower, left, right, front, and rear sides inside the box body 100. The base 300 is installed at the bottom inside the box body 100. An installation groove 301 is formed at the center position inside the base 300;

[0023] When in use, the user first opens the box door 110, then installs the Beidou device to be tested inside the box body 100 through the robotic arm assembly 200, and then fixes the box door 110 through the fixing member 111. After the box door 110 is fixed, the user can start the electromagnetic generator 130 on the upper surface of the box door 110 to perform electromagnetic detection on the Beidou device (the electromagnetic generator 130 is a prior art, and its specific working principle and structure will not be elaborated here). After the detection is completed, the user can take out the Beidou device by performing the reverse operation according to the above steps. Since the box body 100 is equipped with an electromagnetic shielding layer 120 installed on the inner wall, it can effectively block external electromagnetic signals from entering the inside of the box body 100, providing a pure and interference-free electromagnetic environment for the test of the Beidou device. This can ensure that the test results only reflect the performance of the tested Beidou device, without being interfered and affected by external electromagnetic signals, improving the accuracy and reliability of the test data.

[0024] Please refer to Figures 1 to 3 , as the second embodiment of the present invention: A motor 320 is installed at the bottom inside the installation groove 301. The output shaft of the motor 320 is installed with a driving wheel. A rotating column 321 is rotatably installed to the right of the motor 320. A driven wheel is installed on the outer surface of the rotating column 321. A gear belt is installed between the driving wheel and the driven wheel. A rotating seat one 310 is rotatably installed on the upper surface of the base 300 through the rotating column 321;

[0025] A rotating seat two 210 is installed on the upper surface of the rotating seat one 310. A robotic arm one 220 is installed on the upper surface of the rotating seat two 210.

[0027] When in use, a second robotic arm 230 is rotatably mounted at one end of the first robotic arm 220 away from the second rotating base 210, and a third robotic arm 240 is rotatably mounted at one end of the second robotic arm 230 away from the first robotic arm 220. All of the above are rotatably mounted with damping. After the Beidou device is fixed by the robotic claw 250, when the robotic arm assembly 200 needs to rotate, the user can start the motor 320 to rotate the driving wheel on the output shaft of the motor 320. Then, the driving wheel drives the driven wheel to rotate through the gear belt, and the rotation of the driven wheel drives the first rotating base 310 to rotate. The rotation of the first rotating base 310 drives the robotic arm assembly 200 to rotate. Due to the combination of the first robotic arm 220, the second robotic arm 230, and the third robotic arm 240, the robotic claw 250 can achieve multi-degree-of-freedom movement in the three-dimensional space inside the dark box, and can accurately grasp and place the tested Beidou device at the specified position, ensuring the installation accuracy and position accuracy of the testing device. At the same time, the motor 320 and the rotating column 321 drive the robotic arm assembly 200 to rotate 360 degrees in the horizontal direction, so that the Beidou device installed at the end of the robotic arm can be tested at different horizontal angles, comprehensively detecting the signal reception and processing capabilities of the device in all directions.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
