Description

Technical Field

[0001] This utility model relates to the field of RTK technology, and in particular to an RTK radio assembly structure. Background Technology

[0002] RTK (Real-time kinematic) positioning is a measurement method that can obtain centimeter-level positioning accuracy in real time in the field. In existing technologies, in order to reduce the size of RTK equipment, the radio is generally assembled inside the main unit and fixed to the main power PCB board with screws. The connection lines for receiving or transmitting signals from the main unit are soldered to the radio. When it is necessary to repair or replace the radio with one of different power levels, the main unit must be disassembled into the open interior for repair or replacement. This results in low disassembly and assembly efficiency. Furthermore, after disassembly and repair, all functions must be verified before the entire RTK equipment can be reassembled, making assembly cumbersome and maintenance costs high.

[0032] In some embodiments, the assembly steps of the RTK radio assembly structure are as follows: First, the radio 2 is installed on the top of the mounting part 31 and fixed with the first stainless steel screw 4; second, the bottom cover assembly 3, which was assembled in the first step, is installed on the bottom of the main unit 1, specifically so that the radio 2 is located in the second accommodating cavity 111 and connected to the main power PCB board 12 through the opening 112, and the battery 32 is also connected to the main power PCB board 12 through the opening 112. Finally, the mounting part 31 is fixedly connected to the housing 11 with the second stainless steel screw 5. Since the RTK radio assembly structure is modularized into three parts: the main unit 1, the radio 2, and the bottom cover assembly 3, the assembly process is simple and easy to operate. Compared with the prior art, which requires full functional verification after installation, it also shortens the calibration time.
