Description

Technical Field

[0001] This utility model relates to the field of antenna installation, specifically to an integrated mounting base for radio frequency antennas. Background Technology

[0002] In the current era of deep integration between satellite positioning and wireless communication technologies, RTK (Real-time Dynamic Carrier Phase Differential) antennas and radio frequency antennas are core components of drones, smart terminals, autonomous driving equipment, etc. The rationality of their installation directly determines the upper limit of equipment performance. However, existing antenna installation schemes have multiple technical bottlenecks, which seriously restrict the accuracy, stability and practicality of the equipment.

[0003] The RTK antenna is used to search for GPS satellites. The dual antennas point in the direction of each other using the angle between their positions. Theoretically, the two antennas need to maintain a certain distance; the greater the distance, the more accurate the pointing. The RF antenna is used for bidirectional transmission of information between the control terminal and the ground station. Because it uses a new microwave signal with a short wavelength, signal attenuation is significant due to obstruction. Current solutions involve fixing the RTK antenna to both sides of the central plate of the fuselage, and fixing the RF antenna to the rear of the fuselage or the motor base. However, the current dual-antenna installation positions are too concentrated, affecting satellite search and pointing accuracy. Furthermore, the RF antenna is partially obstructed by the fuselage, preventing omnidirectional pointing and making it susceptible to internal signal interference, thus affecting operational stability.

[0004] Currently, RTK dual antennas are susceptible to interference from the device's electronic equipment. The distance between the two antennas is not far enough, resulting in pointing errors. Most RF antennas are located at the rear of the device or at the motor base. When located at the rear of the device, the new signal in some directions will be blocked by the device. The RF cable at the motor base is too long, and the high-frequency vibration caused by the motor rotation will affect the transmission quality of the new signal. Two sets of antennas and two sets of mounting structures increase weight and cost. Therefore, it is necessary to design an integrated RF antenna mounting base to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an integrated mounting base for radio frequency antennas to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated RF antenna mounting base, comprising an upper mounting shell and a lower mounting shell mounted to the upper mounting shell via four bolts. The upper mounting shell is integrally provided with a limiting frame at its top, and the lower mounting shell is integrally provided with a mounting bracket at its bottom. An RTK antenna is mounted on the inner side of the limiting frame via a fixing component, and a rod antenna is mounted on the inner side of the mounting bracket via a mounting component. A wire groove is formed on the top of the upper mounting shell near one side. The rod antenna and the RTK antenna are connected via an SMA connector. The cross-sections of both the upper and lower mounting shells are concave arc-shaped.

[0007] Preferably, the fixing member includes an elastic ring movably mounted to the inner side of the limiting frame, a limiting ring fixedly connected to the top of the limiting frame near the inner side, and a limiting groove formed on the outer side of the RTK antenna.

[0008] Preferably, the connector includes a connecting ring that is movably connected to the bottom inner side of the mounting bracket, and a mounting plate is fixedly connected to the outer side of the rod antenna near one end. The mounting plate is installed and fixed to the mounting bracket by bolts.

[0009] Preferably, the connecting ring has four circumferentially arranged fixing grooves on one side, and the mounting bracket has four circumferentially arranged limiting posts fixedly connected to one end.

[0010] Preferably, one end of the RTK antenna has a spacer ring fixedly extending from it.

[0011] Preferably, a gasket is placed between the upper mounting shell and the lower mounting shell.

[0012] Preferably, anti-slip pads are installed on the inner sides of both the upper and lower mounting shells.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The upper and lower mounting shells are fixed to the two side arms with four bolts. The arms are far from the fuselage, avoiding unnecessary interference from electronic equipment. Furthermore, the RTK antenna has a long range and no obstructions, ensuring satellite acquisition quality and pointing accuracy. The RF antenna of the rod antenna has the smallest obstruction area. The RTK antenna and RF antenna share the same fixing structure, which is lightweight and simple in structure. The RTK antenna is pressed and fixed with the antenna structure through a stepped structure, leaving a wire groove for easy wire passage. The radio rod antenna is connected to the antenna through a reserved SMA connector and locked with screws. The RTK dual antennas have a long range and no obstructions, ensuring satellite acquisition quality and more accurate pointing. The radio antenna has no obstructions on all four axes, ensuring omnidirectional signal quality and ensuring that the RF omnidirectional signal is in optimal condition.

[0015] 2. The RTK antenna passes through the limiting frame at the top of the upper mounting housing, and then the elastic ring is embedded in the limiting frame to support the RTK antenna. The arm is inserted between the upper and lower mounting housings and supports the RTK antenna upward through the elastic ring. At the same time, the limiting ring at the top of the limiting frame is engaged in the limiting groove on the outside of the RTK antenna, which improves the convenience and stability of installing and fixing the RTK antenna.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please refer to Figure 1-7 As shown, this utility model provides an integrated RF antenna mounting base, including an upper mounting shell 1 and a lower mounting shell 2 that is mounted to the upper mounting shell 1 by four bolts. The top of the upper mounting shell 1 is integrally provided with a limiting frame 3, and the bottom of the lower mounting shell 2 is integrally provided with a mounting frame 4. An RTK antenna 5 is mounted on the inner side of the limiting frame 3 by a fixing component, and a rod antenna 6 is mounted on the inner side of the mounting frame 4 by a mounting component. A wire groove 7 is opened on the top of the upper mounting shell 1 and near one side. The rod antenna 6 and the RTK antenna 5 are connected by an SMA connector 8. The cross-sections of the upper mounting shell 1 and the lower mounting shell 2 are both concave arc-shaped. A gasket 17 is placed between the upper mounting shell 1 and the lower mounting shell 2 respectively. Anti-slip pads 18 are installed on the inner side of both the upper mounting shell 1 and the lower mounting shell 2 respectively.

[0027] In addition, the upper mounting shell 1 and the lower mounting shell 2 are fixed to the two side arms with four bolts. The arms are far from the fuselage to avoid unnecessary interference from electronic equipment. Furthermore, the RTK antenna 5 has a long range and is unobstructed, ensuring satellite search quality and pointing accuracy. The RF antenna of the rod antenna 6 has the smallest obstructed area. The RTK antenna 5 and the RF antenna share the same fixing structure, which is lightweight and simple in structure. The RTK antenna 5 is pressed and fixed with the antenna structure through a stepped structure, leaving a wire groove 7 for wires to pass through. The radio rod antenna 6 connects to the antenna through the reserved SMA connector 8 and is locked with screws. The RTK dual antennas have a long range and are unobstructed, ensuring satellite search quality and more accurate pointing. The radio antenna is unobstructed on all four axes, ensuring omnidirectional signal quality and ensuring that the RF omnidirectional signal is in optimal condition.

[0028] Furthermore, a pad 17 is laid between the upper mounting shell 1 and the lower mounting shell 2 to prevent the upper mounting shell 1 and the lower mounting shell 2 from directly contacting each other and causing friction or loosening. The anti-slip pads 18 on the inner side of the upper mounting shell 1 and the lower mounting shell 2 can fit with the machine arm to prevent the upper mounting shell 1 and the lower mounting shell 2 from sliding when they fit with the machine arm.

[0029] Specifically, the fasteners include an elastic ring 9 that is movably installed inside the limiting frame 3, a limiting ring 10 that is fixedly connected to the top of the limiting frame 3 and close to the inside, a limiting groove 11 that is opened on the outside of the RTK antenna 5, and a pad ring 16 that is fixedly extended at one end of the RTK antenna 5.

[0030] The RTK antenna 5 passes through the limiting frame 3 at the top of the upper mounting shell 1, and the elastic ring 9 is embedded in the limiting frame 3 to support the RTK antenna 5. The arm is inserted between the upper mounting shell 1 and the lower mounting shell 2, and the elastic ring 9 supports the RTK antenna 5 upward. At the same time, the limiting ring 10 at the top of the limiting frame 3 is inserted into the limiting groove 11 on the outside of the RTK antenna 5, and the pad ring 16 at the bottom of the RTK antenna 5 is embedded in the top of the elastic frame, which enables the elastic frame to limit the RTK antenna 5, improving the convenience and stability of installing and fixing the RTK antenna 5.

[0031] More specifically, the connector includes a connecting ring 12 that is movably connected to the bottom inner side of the mounting bracket 4, and a mounting plate 13 that is fixedly connected to the outer side of the rod antenna 6 near one end. The mounting plate 13 is installed and fixed to the mounting bracket 4 by bolts. The connecting ring 12 has four circumferentially arranged fixing slots 14 on one side, and four circumferentially arranged limiting posts 15 are fixedly connected to one end of the mounting bracket 4.

[0032] Furthermore, the connecting ring 12 is embedded in the mounting bracket 4, the rod antenna 6 is inserted into the inner side of the connecting ring 12 of the mounting bracket 4, and then bolts are used to install and fix it to the mounting bracket 4 through the mounting plate 13. The limiting post 15 at the bottom of the mounting bracket 4 is inserted into the fixing groove 14 at the top of the connecting ring 12, and the limiting post 15 is used to limit the installation of the connecting ring 12.

[0033] Working principle: First, the RTK antenna 5 passes through the limiting frame 3 at the top of the upper mounting shell 1. Then, the elastic ring 9 is embedded in the limiting frame 3 to support the RTK antenna 5. Next, the connecting ring 12 is embedded in the mounting frame 4. Then, the rod antenna 6 is inserted into the inner side of the connecting ring 12 of the mounting frame 4. Then, bolts are used to install and fix it to the mounting frame 4 through the mounting plate 13. At this time, the limiting post 15 at the bottom of the mounting frame 4 is inserted into the fixing groove 14 at the top of the connecting ring 12. Then, the arm is inserted between the upper mounting shell 1 and the lower mounting shell 2, and the RTK antenna 5 is supported upward by the elastic ring 9. The radio rod antenna 6 is connected to the antenna through the reserved SMA connector 8 and then tightened with screws. Then, the upper mounting shell 1 and the lower mounting shell 2 are fixed to the two arms on both sides with four bolts for installation and fixation. At the same time, the upper mounting shell 1 and the lower mounting shell 2 are fitted together by the gasket 17, and the anti-slip pads 18 on the inner side of the upper mounting shell 1 and the lower mounting shell 2 are fitted together with the arm.
