Description
Technical Field
[0001] The utility model relates to the technical field of unmanned aerial vehicle accessories, in particular to an unmanned aerial vehicle RTK antenna with a shock absorption function. Background Art
[0002] RTK antenna refers to an antenna that uses high-precision positioning carrier phase differential technology. It uses a microwave transmitter to process the differential method of carrier phase observations of two or more measuring stations in real time, and sends the carrier phase collected by the base station to the user receiver to calculate the coordinates by difference. It is currently the most effective way to achieve real-time high-precision positioning and is often installed on the top of a drone for positioning.
[0003] During the flight, the drone is affected by external airflow, blades and motor rotation, and the drone collides with the ground when landing, which will all produce some vibrations. The RTK antenna is usually installed on the top of the drone by bolting. Long-term vibration can easily cause the bolts on the RTK antenna to loosen, and in severe cases, it can easily cause the RTK antenna to fall off. Therefore, when maintaining the drone, it is also necessary to check whether the bolts are loose or falling off, which increases the maintenance steps. If it is fixed by riveting or welding, it will be inconvenient for subsequent maintenance and replacement of the RTK antenna. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a UAV RTK antenna with a shock absorption function to solve the technical problems mentioned in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an RTK antenna for unmanned aerial vehicles with a shock-absorbing function, comprising a base, a bracket running through the middle of the top of the base, and a through hole being opened on the top of the bracket, ribs being connected on both sides of the bracket, a limit block being connected inside the base, and a spring being connected between the limit block and the base.
[0006] By adopting the above technical solution, the bolts are passed through the through holes and tightened to complete the connection between the base and the drone. Then, the bracket is rotated to make the limit block correspond to the through hole. At this time, the spring drives the limit block to move up and enter the through hole, so as to prevent the bracket from continuing to rotate. After the bracket is rotated, the through hole and the bolt are staggered to prevent the bolt from loosening and moving up and separating from the base. At the same time, the ribs and the bolts correspond to increase the compressive capacity of the bracket to prevent the bolts from bending the bottom of the bracket. When disassembly is required, the limit block is first pressed down to separate the limit block from the through hole, and then the bracket is rotated to make the bolt correspond to the through hole, so that the RTK antenna can be disassembled.
[0007] Furthermore, the cross section of the bracket is in the shape of an I, and the bracket is rotatably connected to the base.
[0008] By adopting the above technical solution, after connecting the RTK antenna to the drone, the staff rotates the bracket. After the bracket rotates, the through hole is错开 from the bolt, preventing the bolt from loosening and moving upward to separate from the base.
[0009] Furthermore, the cross-section of the limiting block is in a "ji" shape, and the limiting block is slidably connected to the base and the through hole respectively.
[0010] By adopting the above technical solution, after connecting the RTK antenna to the drone, the staff rotates the bracket to align the limiting block with the through hole. At this time, the spring drives the limiting block to move upward into the through hole, thereby preventing the bracket from continuing to rotate.
[0011] Furthermore, a plurality of rib plates are provided, and the plurality of rib plates are distributed in an annular array.
[0012] By adopting the above technical solution, after the bracket rotates, the through hole is错开 from the bolt, preventing the bolt from loosening and moving upward to separate from the base. At the same time, the rib plate corresponds to the bolt to increase the compressive capacity of the bracket, preventing the bolt from bending the bottom of the bracket.
[0013] Furthermore, two limiting blocks and springs are provided, and the two limiting blocks and springs are symmetrically distributed.
[0014] By adopting the above technical solution, the staff inserts the fingers of both hands into the two through holes respectively. At this time, the fingers of the staff press down the limiting block to separate the limiting block from the through hole. Then, the staff rotates the bracket through the fingers inserted into the through hole to align the bolt with the through hole.
[0015] Furthermore, a column is connected to the top of the bracket, and an antenna main body is installed on the top of the column. A feeder interface is provided on one side of the bottom of the antenna main body, and bolts penetrate through both sides of the bottom of the base.
[0016] By adopting the above technical solution, the staff places the base on the top of the drone, and the mounting holes on the drone correspond to the through holes. Then, the staff passes the bolts through the through holes and tightens them to complete the connection between the base and the drone. Then, the staff connects the feeder to the control compartment and the feeder interface of the drone, enabling the antenna main body to work properly.
[0017] Furthermore, a plurality of bolts and through holes are provided, and the plurality of bolts and through holes are distributed in an annular array.
[0018] By adopting the above technical solution, the staff passes the bolts through the through holes and tightens them to complete the connection between the base and the drone, reducing the possibility of the RTK antenna falling off during flight.
[0019] Furthermore, a first buffer pad is connected to the bottom of the base, and a second buffer pad is connected between the base and the bracket.
[0020] By adopting the above technical solution, the RTK antenna is buffered by the first buffer pad and the second buffer pad during the flight of the UAV, thereby reducing the vibration of the RTK and further reducing the possibility of the bolts loosening and falling off.
[0021] Furthermore, the first buffer pad and the second buffer pad are both made of silicone rubber material.
[0022] By adopting the above technical solution, the rubber has good elasticity and can absorb the energy during vibration, thereby reducing the vibration of the RTK antenna.
[0023] In summary, the utility model mainly has the following beneficial effects:
[0024] The utility model arranges a bracket, a rib plate, a through hole, a limit block and a spring, and a bolt is passed through the through hole and tightened to complete the connection between the base and the drone. Then, the bracket is rotated to make the limit block correspond to the through hole. At this time, the spring drives the limit block to move up and enter the through hole, so that the bracket can be prevented from continuing to rotate. After the bracket is rotated, the through hole and the bolt are staggered to prevent the bolt from loosening and moving up and separating from the base. At the same time, the rib plate and the bolt correspond to increase the pressure resistance of the bracket, and prevent the bolt from bending the bottom of the bracket. When disassembly is required, the limit block is first pressed down to separate the limit block from the through hole, and then the bracket is rotated to make the bolt correspond to the through hole, so that the RTK antenna can be disassembled, thereby reducing the phenomenon that a certain bolt is loosened and falls off to affect the connection strength of the RTK antenna.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0031] The embodiments of the present utility model will be described below according to its overall structure.
[0032] Embodiment 1:
[0033] An unmanned aerial vehicle (UAV) RTK antenna with a shock absorption function, as Figure 1-Figure 4 shown, includes a base 1. A support 2 penetrates through the middle of the top of the base 1. The cross-section of the support 2 is in the shape of a "work" character. The support 2 is rotatably connected to the base 1. A through hole 9 is formed at the top of the support 2. There are multiple through holes 9, and the multiple through holes 9 are distributed in an annular array. Rotate the support 2 so that the limit block 10 corresponds to the through hole 9. At this time, the through hole 9 is错开 from the bolt 11 to prevent the bolt 11 from loosening and moving upward to separate from the base 1. Rib plates 8 are connected to both sides of the support 2. There are multiple rib plates 8, and the multiple rib plates 8 are distributed in an annular array. The rib plates 8 correspond to the bolts 11 to increase the compressive capacity of the support 2 and prevent the bolts 11 from bending the bottom of the support 2. A limit block 10 is connected inside the base 1. The cross-section of the limit block 10 is in the shape of a "ji" character. The limit block 10 is slidably connected to the base 1 and the through hole 9 respectively. A spring 12 is connected between the limit block 10 and the base 1. There are two limit blocks 10 and springs 12, and the two limit blocks 10 and springs 12 are symmetrically distributed. The spring 12 drives the limit block 10 to move upward into the through hole 9, so as to prevent the support 2 from continuing to rotate.
[0034] Refer to Figure 1-Figure 4 , in the above embodiment, a column 3 is connected to the top of the support 2 to raise the position of the antenna body 4 for better operation of the antenna body 4; an antenna body 4 is installed at the top of the column 3. A feeder interface 5 is provided on one side of the bottom of the antenna body 4 for receiving and transmitting signals. Bolts 11 penetrate through both sides of the bottom of the base 1. There are multiple bolts 11, and the multiple bolts 11 are distributed in an annular array, facilitating the installation of the RTK antenna on the top of the UAV.
[0035] Embodiment 2:
[0036] On the basis of the above Embodiment 1, although by setting the support 2, rib plates 8, through holes 9, limit blocks 10 and springs 12, the phenomenon that the connection strength of the RTK antenna is affected by the loosening and falling off of a certain bolt can be reduced; however, the vibration still exists. Embodiment 1 only prolongs the time required for the bolts and the RTK antenna to fall off due to vibration. In the long run, all the bolts 11 may still loosen and fall off after loosening; now, by setting the first buffer pad 6 and the second buffer pad 7, the vibration received by the RTK can be reduced.
[0037] Refer to Figure 1-Figure 4In the above embodiment, a first buffer pad 6 is connected to the bottom of the base 1, and a second buffer pad 7 is connected between the base 1 and the bracket 2. The first buffer pad 6 and the second buffer pad 7 are both made of silicone rubber material. During the flight of the drone, the RTK antenna is buffered by the first buffer pad 6 and the second buffer pad 7 to reduce the vibration of the RTK, so as to further reduce the possibility of the bolt 11 loosening and falling off.
[0038] The implementation principle of the utility model is as follows: first, the staff places the base 1 on the top of the drone, and the mounting hole on the drone corresponds to the through hole 9, then the staff passes the bolt 11 through the through hole 9 and tightens it to complete the connection between the base 1 and the drone, and then the staff connects the feeder to the control cabin of the drone and the feeder interface 5, so that the antenna body 4 can operate normally;
[0039] After connecting the RTK antenna to the drone, the staff rotates the bracket 2 to make the limit block 10 correspond to the through hole 9. At this time, the spring 12 drives the limit block 10 to move up and enter the through hole 9, so as to prevent the bracket 2 from continuing to rotate. After the bracket 2 rotates, the through hole 9 and the bolt 11 are staggered to prevent the bolt 11 from loosening and moving up and separating from the base 1. At the same time, the rib plate 8 corresponds to the bolt 11 to increase the compressive capacity of the bracket 2, and prevent the bolt 11 from bending the bottom of the bracket 2. At the same time, the RTK antenna is buffered by the first buffer pad 6 and the second buffer pad 7 during the flight of the drone to reduce the vibration of the RTK, so as to further reduce the possibility of the bolt 11 loosening and falling off;
[0040] When the RTK antenna needs to be disassembled, the staff inserts the fingers of both hands into the two through holes 9 respectively. At this time, the staff's fingers press down the limit block 10 to separate the limit block 10 from the through hole 9. Then the staff rotates the bracket 2 by inserting the fingers into the through hole 9 to make the bolt 11 correspond to the through hole 9. At this time, the staff can loosen the bolt 11 to disassemble, repair and replace the RTK antenna.
