Description

Technical Field

[0001] This invention relates to the field of RTK, and more specifically to an RTK device with a built-in radio. Background Technology

[0002] RTK (Real-time kinematic) carrier phase differential technology is a method for processing the carrier phase observations of two measurement stations in real time. It transmits the carrier phase data collected by the base station to the user receiver, where the difference is calculated to determine the coordinates. This is a new and commonly used satellite positioning measurement method. Previous static, rapid static, and dynamic measurements all required post-processing to achieve centimeter-level accuracy. RTK, however, is a measurement method that can obtain centimeter-level positioning accuracy in real time in the field. It employs a dynamic real-time carrier phase differential method and represents a significant milestone in GPS applications. Its emergence has brought new measurement principles and methods to engineering layout, topographic mapping, and various control surveys, greatly improving operational efficiency.

[0003] The radio is a crucial component of RTK equipment. However, the current installation structures and methods for built-in RTK radios are cumbersome, complex, and costly. Most existing RTK radios are installed and fixed using double-ended copper pillars and multiple nuts. Both ends of the double-ended copper pillars need to be tightened with nuts for a secure connection. During installation, the double-ended copper pillars must be aligned and installed before each nut is removed and tightened. This significantly reduces assembly efficiency, leading to longer assembly times, lower production efficiency, and higher production costs. Furthermore, the double-ended copper pillars have poor self-locking ability; even with nuts tightened on both sides, they are prone to loosening after a period of use, causing instability in the connection between the radio and the motherboard. This makes the radio installation structure highly unstable and unreliable when facing varied, complex, and challenging outdoor testing environments, prone to poor contact or even disconnection.

[0004] Therefore, there is an urgent need for an RTK device with a simpler and faster structure and assembly, lower cost, and more stable radio installation. Summary of the Invention

[0005] To overcome the shortcomings mentioned above, the present invention aims to provide a technical solution that can solve the above problems.

[0006] An RTK device with a built-in radio includes a motherboard, a radio, and a mounting bracket. The radio has multiple mounting holes on its side, and the mounting bracket has at least one corresponding to each mounting hole. The mounting bracket is used to connect the motherboard and the radio.

[0007] The fixing component includes an integrally formed left fixing block and a right fixing block, which are mirror images of each other. Both the left and right fixing blocks are provided with guide grooves for engaging with the radio. The left and right fixing blocks are also provided with through holes that correspond to the mounting holes and penetrate the guide grooves. A fixing nut is embedded in the through hole. The fixing component engages with and fixes the radio through the guide grooves, and the connection between the radio and the main board is achieved by a fixing bolt passing through the main board, the guide groove, and the mounting hole in sequence and engaging with the fixing nut.

[0008] Preferably, when the fixing component is integrally injection molded, the fixing nut is embedded in both the left fixing block and the right fixing block.

[0009] Preferably, the guide groove is provided with a rib, which is used to limit and fix the radio to prevent the radio from shaking relative to the fixing member.

[0010] Preferably, the PCB board of the radio is provided with a male connector, and the motherboard is provided with a female connector corresponding to the male connector. The male connector and the female connector are used for signal connection and power supply between the radio and the motherboard.

[0011] Preferably, the radio station has a TNC signal terminal on the side away from the motherboard, and the TNC signal terminal is connected to a TNC connector mounted on the bottom shell via a signal line.

[0012] The TNC connector is also connected to a radio antenna, which is used to receive signals transmitted by other radio stations.

[0013] Preferably, the battery is assembled in the battery slot of the bottom shell and fixed by a battery pressure plate and bolts.

[0014] Preferably, a GNSS antenna shielding shell is provided above the motherboard, and a GNSS antenna is installed inside the GNSS antenna shielding shell. The GNSS antenna is used to receive satellite signals.

[0015] Preferably, the GNSS antenna shielding shell is further provided with a top cover, which is fastened and fixed to the bottom shell to form a cavity, the cavity being used to accommodate the aforementioned motherboard, radio, fixing component, mounting plate, battery, TNC connector and GNSS antenna shielding shell.

[0016] A sealing ring is provided between the bottom shell and the top cover to seal the cavity.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In the RTK device with a built-in radio of the present invention, the radio can be firmly fixed to the motherboard by the fastener and will not easily loosen or fall off; and the installation of the radio is simpler and faster, without having to align multiple nuts and tighten them one by one before installation, or flipping it over to install the nuts on the other side.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] Furthermore, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Please see Figures 1-4 In this embodiment of the invention, there are a motherboard 1, a radio 2 and a fixing member 3. The radio 2 has a plurality of mounting holes 4 on its side. The fixing member 3 is provided with at least one corresponding to the mounting hole 4. The fixing member 3 is used to connect the motherboard 1 and the radio 2.

[0031] The fixing component 3 includes an integrally formed left fixing block 5 and a right fixing block 6, which are mirror images of each other. Both the left fixing block 5 and the right fixing block 6 are provided with guide grooves 7, which are used to fit with the radio 2. The left fixing block 5 and the right fixing block 6 are also provided with through holes 8 that correspond to the mounting holes 4 and penetrate the guide grooves 7. A fixing nut 9 is embedded in the through hole 8. The fixing component 3 fits and fixes the radio 2 through the guide grooves 7, and the fixing bolts 10 pass through the main board 1, the guide grooves 7, and the mounting holes 4 in sequence before cooperating with the fixing nut 9 to achieve the connection between the radio 2 and the main board 1.

[0032] It should be noted that in the traditional installation structure of the fixed radio 2, the double-headed copper pillars require each nut to be aligned and tightened. After tightening one side, the assembly of the radio 2 and the main board 1 needs to be flipped to tighten the nut on the other side. In this invention, multiple fixing nuts 9 are integrally formed in the fixing component 3, and the fixing component 3 is first fitted and connected to the radio 2 through the guide groove 7. Then, only the fixing bolt 10 needs to be screwed in from the side of the main board 1 to fasten the radio 2 and the main board 1 together, without having to take out the nuts one by one and tighten them one by one. This is more time-saving and labor-saving, and the assembly efficiency is higher. It is also more adaptable to automated assembly to further improve production efficiency. At the same time, it reduces the amount of nuts by half and can be mass-produced by integral injection molding, which not only reduces the production cost but also allows for better control of the size. It should also be noted that in some other embodiments, the fixing nuts 9 do not need to be embedded in the through hole 8. Instead, the threads are directly machined in the through hole 8. The advantage of this structure is that the size can be selected and processed according to the requirements, further reducing the production cost.

[0033] When the fastener 3 is integrally injection molded, a fixing nut 9 is embedded in both the left fixing block 5 and the right fixing block 6. This structure can eliminate the alignment and rotation process of the nut, saving assembly time. In some other embodiments, the through hole 8 is directly machined with threads without the need to embed the fixing nut 9, which will result in lower production costs.

[0034] The guide groove 7 is provided with a protruding rib 11, which is used to limit and fix the radio 2 to prevent the radio 2 from shaking relative to the fixing part 3. The protruding rib 11 can make the connection between the fixing part 3 and the radio 2 more stable. During the transfer and installation process, the radio 2 will not shake relative to the fixing part 3, which will cause the mounting hole 4 on the radio 2 to become out of concentric with the through hole 8 on the fixing part 3, resulting in the failure of the installation of the fixing bolt 10.

[0035] Radio 2 has a male connector 12 on its PCB board. Radio 2 is assembled from the PCB board and two shielding shells. The main board 1 has a female connector corresponding to the male connector 12. The male connector 12 and the female connector are used for signal connection and power supply between radio 2 and the main board 1. Radio 2 has a TNC signal terminal on the side away from the main board 1. The TNC signal terminal is connected to a TNC connector 13 installed on the bottom shell through a signal line. The TNC connector 13 is also connected to a radio antenna 14, which is used to receive signals transmitted by other radios 2. The battery 15 slot in the bottom shell is equipped with a battery 15 and is fixed by a battery clamping plate 16 and bolts. A GNSS antenna shielding shell 17 is also provided above the main board 1. A GNSS antenna 18 is installed in the GNSS antenna shielding shell 17 and is used to receive satellite signals. The GNSS antenna shielding shell 17 is also provided with a top cover 19. The top cover 19 is fastened to the bottom shell to form a cavity. A sealing ring 20 is provided between the bottom shell and the top cover 19 to seal the cavity.

[0036] It should be noted that in the assembly process of the RTK equipment, the first step is to assemble the TNC connector 13 onto the hole in the base shell and tighten it with screws.

[0037] The second step is to place the battery 15 into the battery 15 slot in the bottom shell and install the battery pressure plate 16, and then use screws to tighten the battery pressure plate 16 to fix it.

[0038] The third step is to put the two fasteners 3 onto the radio 2 in the direction of the guide groove 7, and then assemble the radio 2 with the fasteners 3 on it onto the main board 1 in the direction of the male connector 12 and the female connector. Then, use the fixing bolts 10 to lock and fix the radio 2 from the main board 1.

[0039] The fourth step is to place the motherboard 1 of the assembled radio 2 onto the bottom housing assembly in the corresponding position, tighten it with screws, and connect the TNC signal cable to the radio 2.

[0040] The fifth step is to assemble the GNSS antenna 18 into the GNSS antenna shield 17 according to the corresponding position and tighten it with screws. Then, assemble the GNSS antenna 18 and GNSS antenna shield 17 into the bottom shell assembly according to the corresponding position and tighten it with screws.

[0041] The sixth step is to assemble the decorative ring onto the bottom shell assembly, then assemble the top cover 19 into the corresponding position onto the bottom shell assembly and tighten it with screws from the screw holes at the bottom of the bottom shell assembly. Finally, screw the radio antenna 14 onto the TNC connector 13 of the bottom shell assembly and screw on the centering rod to complete the assembly of the whole machine.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
