[0001] The utility model relates to the technical field of radio remote control equipment, and particularly relates to an unmanned aerial vehicle (UAV) antenna bracket and a UAV. Background Art

[0002] The UAV antenna is a key component for realizing information transmission between the UAV and the ground control station, other UAVs or other communication devices. Its basic principle is to achieve signal transmission and reception through the radiation and reception of electromagnetic waves. The design of the UAV antenna needs to consider multiple factors such as the flight altitude, speed, direction, and communication distance of the UAV to ensure stable and efficient communication in various complex environments.

[0003] In the prior art, most of the GPS antennas on UAVs are tightly attached to the UAV body. Due to the interference of the UAV body, the signal of the GPS antenna will become weak, resulting in a shorter signal reception distance. Moreover, since the UAV is prone to various influences such as air flow and user operation during high-altitude flight, the UAV body will generate a shaking phenomenon, and thus the GPS antenna is also interfered by the oscillation of the UAV body, resulting in poor signal reception ability of the GPS antenna.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0039] The present utility model provides a drone antenna bracket. Referring to Figures 1 to 4 , the drone antenna bracket specifically includes a base 1, a support frame 2, a mounting seat 3, a locking member 4, and a loosening prevention member 5.

[0040] Among them, the base 1 can be installed on the drone body, and the base 1 is used to mount the support frame 2 for the GPS antenna 10. Exemplarily, a plurality of mounting holes are provided on the base 1, and the plurality of mounting holes are installed on the drone body through screws, which is convenient for quick installation and disassembly.

[0041] One end of the support frame 2 is movably connected to the base 1. In this embodiment, the movable connection manner between the support frame 2 and the base 1 can be a sliding connection, a rotational connection, etc., as long as the support frame 2 can be movably connected to the base 1. The embodiments of the present application do not make limitations here.

[0042] The mounting seat 3 is disposed at the end of the support frame 2 away from the base 1 and is used to mount the GPS antenna 10.

[0043] As an implementation manner, the mounting seat 3 can be provided with a connection groove and sleeved on the end of the support frame 2 away from the base 1, so that the contact area between the mounting seat 3 and the support frame 2 is increased, the connection stability between the mounting seat 3 and the support frame 2 is improved, and it is more beneficial for the support frame 2 to bear the weight of the GPS antenna 10.

[0044] The locking member 4 is movably connected to the support frame 2 and is used to cooperate with the base 1 to lock the support frame 2 onto the base 1.

[0045] Exemplarily, the locking member 4 can slide up and down along the support frame 2. When the drone is in use, the support frame 2 is rotated relative to the base 1 to an upright state, and the locking member 4 is slid along the support frame 2 to the abutting position with the base 1 to lock the base 1 and the support frame 2, so that the support frame 2 maintains an upright state, thereby creating a certain height difference between the GPS antenna 10 and the drone body, preventing the signal of the GPS antenna 10 from weakening due to the influence of the drone body, and thus ensuring the signal receiving distance.

[0046] The anti-loosening member 5 is disposed outside the support frame 2 and / or the base 1, and the anti-loosening member 5 is used to respectively press and contact the inner side of the locking member 4 and the outer side of the support frame 2 and / or the base 1 when the locking member 4 locks the support frame 2 to the base 1.

[0047] When the drone is flying at high altitude, it is easily affected by air currents and the operations of the user, etc., resulting in the drone body shaking in the air. At the same time, the drone antenna bracket will also shake and is prone to looseness and deflection. In the embodiment of the present application, by providing the anti-loosening member 5 outside the support frame 2 and / or the base 1, when the locking member 4 locks the support frame 2 to the base 1, the anti-loosening member 5 respectively presses and contacts the inner side of the locking member 4 and the outer side of the support frame 2 and / or the base 1, and the frictional force between the inner side of the locking member 4 and the anti-loosening member 5 and between the outer side of the base 1 and the anti-loosening member 5 is utilized to increase the firmness between the locking member 4 and the base 1, thereby increasing the installation stability between the support frame 2 and the base 1, ensuring that the drone antenna bracket is not easily loosened due to shaking during the flight of the drone, and avoiding the GPS antenna 10 being interfered by the oscillation of the drone body and resulting in a poor signal receiving ability of the GPS antenna 10.

[0048] It should be noted that the anti-loosening member 5 can be disposed on the outer side of the support frame 2, can also be disposed on the outer side of the base 1, and can also be disposed on the outer sides of both the support frame 2 and the base 1 at the same time to further increase the locking ability of the locking member 4 to the support frame 2. The specific setting method depends on actual needs and is not limited in the present utility model.

[0049] As a preferred embodiment of the embodiment of the present application, one end of the support frame 2 is rotatably connected to the base 1. In this embodiment, one end of the support frame 2 can be rotatably connected to the base 1 through a rotating shaft. When the drone antenna bracket is needed, the support frame 2 is rotated to an upright state, and when the drone antenna bracket is not needed, the support frame 2 is rotated to a lying state, reducing the space occupied by the drone antenna bracket and facilitating carrying.

[0050] Further, the support frame 2 includes a rotating base 21 and a support rod portion 22. One end of the rotating base 21 is rotatably connected to the base 1. One end of the support rod portion 22 is connected to the end of the rotating base 21 away from the base 1, and the end of the support rod portion 22 away from the rotating base 21 is connected to the mounting base 3.

[0051] In this embodiment, the support rod portion 21 and the rotating base 21 are separately designed, which is beneficial to the quick installation and disassembly of the support frame 2. The mounting base 3 and the support rod portion 22 can also be separately designed, which can also facilitate disassembly and maintenance.

[0052] Of course, in other embodiments, the support rod portion 22, the rotating base 21, and the mounting base 3 can also be integrally formed structures to improve the overall structural strength.

[0053] Further, the base 1 is provided with an inner cavity 6, an axial opening 101 communicating with the inner cavity 6, and a lateral opening 102 communicating with the inner cavity 6. One end of the rotating base 21 is rotatably connected to the inner cavity 6 through the axial opening 101, and the lateral opening 102 is used to avoid the rotation of the rotating base 21 relative to the base 1.

[0054] In this embodiment, at a position on the side of the base 1 corresponding to the rotating base 21, a lateral opening 102 communicating with the inner cavity 6 is provided for the rotating base 21 to rotate inside the base 1 to drive the support frame 2 to rotate, avoiding interference between the rotating base 21 and the base 1.

[0055] Further, the base 1 has a first abutting end face 103 arranged along its height direction, and the rotating base 21 has a second abutting end face 214 arranged towards the first abutting end face 103. The locking member 4 is used to lock the rotating base 21 to the base 1 when the first abutting end face 103 abuts against the second abutting end face 214.

[0056] When the drone needs to be used, the support frame 2 will be driven by the rotating base 21 to rotate into an upright state. At this time, the first abutting end face 103 will abut against the second abutting end face 214, and then the locking member 4 will move to lock the rotating base 21 to the base 1, further increasing the contact area between the rotating base 21 and the base 1 and improving the connection stability.

[0057] Among them, the shapes of the first abutting end face 103 and the second abutting end face 214 can be flat surfaces, or concave and convex shapes that cooperate with each other. The present utility model does not limit this here.

[0058] Further, the locking member 4 is sleeved outside the support rod portion 22, and the locking member 4 can slide relative to the support rod portion 22 to lock the rotating base 21 to the base 1.

[0059] When the drone is not needed, the locking member 4 slides upward along the support frame 2, and the locking member 4 will move away from the base 1. At this time, the rotating seat 21 is released, and the rotating seat 21 can rotate to drive the support frame 2 to rotate toward the side close to the drone body, facilitating the storage and carrying of the drone.

[0060] When the drone needs to be used, the locking member 4 slides downward along the support frame 2, and the locking member 4 will abut against the base 1, locking the rotating seat 21 on the base 1 to ensure that the support frame 2 remains upright, so that the GPS antenna 10 has a good signal reception distance.

[0061] Further, the rotating seat 21 includes a first cylinder 211 and a second cylinder 212. The diameter of the first cylinder 211 is larger than that of the second cylinder 212. The first cylinder 211 is connected to the second cylinder 212 and a step 213 is formed at the connection.

[0062] The locking member 4 axially penetrates through a first hole section 41 and a second hole section 42. The diameter of the first hole section 41 is larger than that of the second hole section 42. The first hole section 41 is used to accommodate the first cylinder 211 and the base 1, and the second hole section 42 is used to accommodate the support rod portion 22. When the locking member 4 locks the rotating seat 21 to the base 1, the inner top surface 43 of the locking member 4 abuts against the step 213.

[0063] It can be understood that the rotating seat 21 is integrally formed by the first cylinder 211 and the second cylinder 212, and the diameter of the first cylinder 211 is larger than that of the second cylinder 212. A step 213 is formed between the first cylinder 211 and the second cylinder 212. When the locking member 4 moves along the support frame 2 toward the direction close to the base 1, the locking member 4 can abut against the step 213. At this time, when the moving distance of the locking member 4 reaches the lower limit, the rotating seat 21 can be locked and fixed.

[0064] The locking member 4 is integrally formed by the first hole section 41 and the second hole section 42, and the diameter of the first hole section 41 is larger than that of the second hole section 42. When the locking member 4 abuts against the rotating seat 21, the first hole section 41 is located at the first cylinder 211 of the base 1, and the inner top surface 43 of the second hole section 42 abuts against the step 213, locking the rotating seat 21 on the base 1.

[0065] Further, the inner surface of the locking member 4 is provided with internal threads, and the outer surface of the base 1 is provided with external threads 104. The internal threads are in threaded cooperation with the external threads 104 to connect the locking member 4 and the base 1, facilitating the quick locking and unlocking of the rotating seat 21 and the base 1.

[0066] Further, the base 1, the support frame 2, and the mounting seat 3 axially penetrate through a wire routing cavity 11 for the wire 7 of the GPS antenna 10 to pass through.

[0067] The drone antenna bracket further includes a wire fixing member 8. The wire fixing member 8 is sleeved on the periphery of the wiring harness 7 and abuts against the inner side wall of the support frame 2 for fixing the wiring harness 7 within the support frame 2.

[0068] It can be understood that the base 1, the support frame 2, and the mounting base 3 are internally provided with a mutually connected wiring cavity 11, which can accommodate the wiring harness 7 of the GPS antenna 10. A wire fixing member 8 is also arranged in the wiring cavity 11 of the support frame 2, and the wiring harness 7 is threaded through the wire fixing member 8.

[0069] As an implementation manner, the wire fixing member 8 can be made of sponge material and is arranged inside the wiring cavity 11 of the support frame 2 to fix the wiring harness 7 within the support frame 2, guide the inlet and outlet of the wiring harness 7, and also protect the wiring harness 7 from shaking. Of course, the wire fixing member 8 can also be made of other materials, such as silicone material, etc., and the present utility model does not limit this here.

[0070] Exemplarily, two wire fixing members 8 are provided and are respectively arranged at the upper and lower ends of the wiring cavity 11 of the support frame 2 to improve the installation stability of the wiring harness 7. Of course, the number of the wire fixing members 8 can also be other numbers, and the embodiments of the present application do not limit this here.

[0071] The present utility model also proposes a drone, including: a drone body, a drone antenna bracket, and a GPS antenna 10. The drone antenna bracket is installed on the drone body; the GPS antenna 10 is installed on the mounting base 3 of the drone antenna bracket.

[0072] Since the drone adopts all the technical solutions of all the embodiments of the above drone antenna bracket, the drone of the present utility model also has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.
