Description

Technical Field

[0001] This invention relates to the technical field of unmanned aerial vehicles (UAVs), and more specifically, to an antenna adjustment structure for UAVs. Background Technology

[0002] Currently, images captured by drones and control signals are transmitted wirelessly. In order to transmit signals further, antennas are installed on the drones, and a remote control device on the ground is used to receive the communication signals from the antennas.

[0003] In existing technologies, antennas are fixed to the drone's arms or even the fuselage, preventing them from swinging relative to the drone and thus limiting their orientation. Antennas have a specific directionality when transmitting communication signals. When the drone's antenna is pointing directly at the ground receiver, the transmission distance is greater and the signal is smoother. However, when the drone's attitude changes, causing the antenna to deviate from its intended direction, the transmission distance shortens, and signal interruptions or stutters become more likely. Summary of the Invention

[0004] The purpose of this invention is to provide an antenna adjustment structure for unmanned aerial vehicles (UAVs) to solve the problem that the antennas of UAVs cannot dynamically adjust their orientation in the prior art.

[0005] The present invention is implemented as follows: a UAV antenna adjustment structure includes a primary servo, a secondary servo, and an antenna. The primary servo has a primary output shaft, and the secondary servo has a secondary output shaft. The primary output shaft is connected to a transmission frame, the transmission frame is connected to the secondary servo, the secondary output shaft is connected to a mounting frame, and the antenna is connected to the mounting frame.

[0006] The primary output shaft drives the secondary servo motor to rotate via a transmission frame, and the secondary output shaft drives the antenna to rotate via a mounting frame; the primary output shaft and the secondary output shaft are spatially offset and spatially perpendicular.

[0007] One end of the transmission frame is connected to the primary output shaft, and the other end of the transmission frame has two clamping arms arranged in opposite directions at intervals. The two clamping arms enclose a clamping space with an outer opening. The secondary servo is embedded in the clamping space, and the two clamping arms clamp the secondary servo in opposite directions so that the transmission frame is fixedly connected to the secondary servo.

[0008] The transmission frame is bent in the middle, forming a bent section. The bent section has a hollowed-out area that extends along the bending direction of the bent section.

[0009] Furthermore, the secondary servo is cuboid in shape, and the bottom of the clamping space has a bottom wall; the two clamping arms clamp the two ends of the secondary servo, the inner side of the secondary servo abuts against the bottom wall, and the outer side of the secondary servo is exposed on the outer opening.

[0010] Furthermore, end plates are respectively attached to both sides of the secondary servo motor, the clamping arm and the end plate are stacked in an abutment position, and the clamping arm and the end plate are connected by screws, which fix the clamping arm and the end plate in place.

[0011] Furthermore, the top of the screw has an end, the screw moves through the end plate, the screw is threadedly connected to the clamping arm, and the end abuts against the end plate.

[0012] Furthermore, the end plate is provided with a central through hole, the screw has a movable section that moves through the central through hole and a threaded section that is threadedly connected to the clamping arm, and there is an annular gap between the movable section and the inner wall of the central through hole; the outer periphery of the movable section is provided with an elastic spiral rib, and the spiral rib is arranged spirally along the outer periphery of the movable section.

[0013] The two ends of the spiral rib are fixedly connected to the movable section, and the middle part of the spiral rib is movably arranged with the movable section; the spiral rib is placed in the annular interval and is in an elastic deformation state; during the process of the threaded section being screwed into the clamping arm and being threadedly connected to the clamping arm, the movable section is screwed into the through hole, and the spiral rib is squeezed by the screwing and is elastically deformed away from the spiraling direction of the spiral rib.

[0014] Furthermore, the spiral rib has multiple fixed positions in the middle, the fixed positions are fixedly connected to the movable section, the multiple fixed positions are arranged sequentially at intervals along the spiraling direction of the spiral rib, and the spiral rib has a free section located between adjacent fixed positions.

[0015] During the elastic deformation of the spiral rib, the fixed position and the movable section remain fixed, while the free section is subjected to spiral compression and elastically deforms away from the spiral direction of the spiral rib.

[0016] Furthermore, one end of the transmission frame has a transmission sleeve, and the transmission sleeve has a transmission hole. The first-stage output shaft passes through the transmission hole and is connected to the transmission sleeve as a whole. The inner sidewall of the transmission hole is recessed outward to form multiple longitudinal grooves, and the multiple longitudinal grooves are arranged around the circumference of the transmission hole at intervals.

[0017] The longitudinal groove is filled with elastic material to form a longitudinal elastic strip; the primary output shaft abuts against the inner wall of the transmission hole, and the multiple transverse elastic strips are compressed and deformed towards the longitudinal groove by the pressure of the primary output shaft. The multiple longitudinal elastic strips press against the primary output shaft, thus axially and elastically fixing the primary output shaft and the transmission sleeve.

[0018] Furthermore, the inner wall of the transmission hole has multiple adjacent segments, which are arranged at circumferential intervals around the transmission hole, and the adjacent segments are located between adjacent longitudinal grooves.

[0019] The adjacent sections have recessed transverse grooves filled with elastic material to form transverse elastic strips. Multiple transverse elastic strips are compressed and deformed towards the transverse grooves by the pressure of the primary output shaft.

[0023] The nut is screwed toward the mounting plate to compress and deform the plurality of elastic shafts, increasing the diameter of the elastic shafts. The elastic shafts press against the inner wall of the circumferential hole. The elastic shafts are deformed by the nut and the end ring pressing against each other. Elastic gaps are formed between the end ring and the mounting plate, and between the mounting plate and the nut.

[0024] Furthermore, the inner wall of the circumferential hole is recessed outward to form a circumferential annular groove, which is arranged around the circumference of the circumferential hole; when the elastic shaft is squeezed and deformed, the middle part of the elastic shaft protrudes towards the circumferential annular groove to form an embedded ring embedded in the circumferential annular groove.

[0025] Compared with the prior art, the UAV antenna adjustment structure provided by the present invention can realize the full range of antenna swing adjustment through the rotation adjustment of the primary servo and the secondary servo, so as to adjust the signal transmission direction of the antenna and realize the dynamic adjustment of the antenna, so as to achieve better communication between the UAV and the ground and avoid the phenomenon of communication lag or interruption of the UAV.

[0026] Secondly, the primary output shaft and the secondary output shaft are spatially staggered, and the transmission frame is arranged in a bent shape, which facilitates the positional arrangement between the primary and secondary servos, so that the antenna can achieve a wider range of swing.

[0027] Furthermore, the bent section has a hollow area, and the hollow area extends along the bending direction of the bent section, which can reduce the weight of the bent section while giving it a certain deformation buffering capacity.

[0028] In addition, the two clamping arms of the transmission frame clamp the secondary servo in opposite directions, which facilitates the connection with the secondary servo and allows the entire secondary servo to swing smoothly, avoiding large vibrations. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0040] Reference Figures 1-8 The image shown is a preferred embodiment of the present invention.

[0041] The UAV antenna adjustment structure includes a primary servo motor 100, a secondary servo motor 200, and an antenna 300. The primary servo motor 100 has a primary output shaft, and the secondary servo motor 200 has a secondary output shaft. The primary output shaft is connected to a transmission frame 400, which is connected to the secondary servo motor 200. The secondary output shaft is connected to a mounting frame 500, and the antenna 300 is connected to the mounting frame 500.

[0042] The primary output shaft drives the secondary servo motor 200 to rotate via the transmission frame 400, and the secondary output shaft drives the antenna 300 to rotate via the mounting frame 500; the primary output shaft and the secondary output shaft are spatially offset and spatially perpendicular.

[0043] One end of the transmission frame 400 is connected to the primary output shaft, and the other end of the transmission frame 400 has two clamping arms 401 arranged in opposite directions at intervals. The two clamping arms 401 enclose a clamping space 404 with an outer opening. The secondary servo 200 is embedded in the clamping space 404, and the two clamping arms 401 clamp the secondary servo 200 in opposite directions so that the transmission frame 400 and the secondary servo 200 are fixedly connected.

[0044] The transmission frame 400 is bent in the middle, forming a bent section 407. The bent section 407 has a hollowed-out area 402, which extends along the bending direction of the bent section 407.

[0045] In practical applications, the controller obtains the drone's attitude data, including the drone's current GPS position, altitude relative to the takeoff point, and ground-based GPS position data. It calculates the orientation of the antenna 300 and adjusts the rotation of the primary servo 100 and the secondary servo 200 to adjust the signal transmission direction of the antenna 300, so that the signal strength received by the ground end reaches the ideal state. This improves the transmission distance and smoothness of drone images and control signals, enhancing the consumer experience.

[0046] The aforementioned UAV antenna adjustment structure allows for full-range swing adjustment of the antenna 300 through the rotation adjustment of the primary servo motor 100 and the secondary servo motor 200. This adjusts the signal transmission direction of the antenna 300 and enables dynamic adjustment of the antenna 300, resulting in better communication between the UAV and the ground and preventing communication lag or interruption.

[0047] Secondly, the primary output shaft and the secondary output shaft are spatially offset, and the transmission frame 400 is arranged in a bent shape, which facilitates the positional arrangement between the primary servo 100 and the secondary servo 200, so that the antenna 300 can achieve a wider range of swing.

[0048] Furthermore, the bent section 407 has a hollow area 402, and the hollow area 402 extends along the bending direction of the bent section 407. While ensuring that the weight of the bent section 407 is reduced, the bent section 407 can have a certain deformation buffering capacity.

[0049] In addition, the two clamping arms 401 of the transmission frame 400 clamp the secondary servo 200 in opposite directions, which facilitates the connection with the secondary servo 200 and allows the entire secondary servo 200 to swing smoothly, avoiding large vibrations.

[0050] In this embodiment, the secondary servo 200 is cuboid in shape, and the bottom of the clamping space 404 has a bottom wall 405; two clamping arms 401 clamp the two ends of the secondary servo 200, the inner side of the secondary servo 200 abuts against the bottom wall 405, and the outer side of the secondary servo 200 is exposed on the outer opening.

[0051] In this way, the bottom wall 405 and the two clamping arms 401 make multi-position contact with the secondary servo motor 200, thereby making the connection between the transmission frame 400 and the secondary servo motor 200 more stable.

[0052] In this embodiment, end plates 201 are respectively mounted on both sides of the secondary servo motor 200. The clamping arm 401 and the end plate 201 are stacked together in an abutment position. The clamping arm 401 and the end plate 201 are connected by a screw 700, which fixes the clamping arm 401 and the end plate 201 in place.

[0053] The clamping arm 401 is stacked with the end plate 201 and connected by the screw 700. The clamping arm 401 clamps the end of the secondary servo 200, thereby enabling the clamping arm 401 to connect to the secondary servo 200 in multiple directions, so as to better connect the transmission frame 400 and the secondary servo 200.

[0054] In this embodiment, the top of the screw 700 has an end 701. The screw 700 moves through the end plate 201 and is threadedly connected to the clamping arm 401. The end 701 abuts against the end plate 201. This facilitates the connection between the screw 700 and the clamping arm 401, and the end 701 can press against the end plate 201, thereby realizing the connection between the end plate 201 and the clamping arm 401.

[0055] In this embodiment, the end plate 201 is provided with a central through hole, the screw 700 has a movable section 702 that moves through the central through hole and a threaded section 703 that is threadedly connected to the clamping arm 401, and there is an annular gap 202 between the movable section 702 and the inner sidewall of the central through hole; the outer periphery of the movable section 702 is provided with an elastic spiral rib 704, and the spiral rib 704 is arranged spirally along the outer periphery of the movable section 702.

[0056] Both ends of the spiral rib 704 are fixedly connected to the movable section 702, and the middle part of the spiral rib 704 is movably arranged with the movable section 702. The spiral rib 704 is placed in the annular interval 202 and is in an elastic deformation state. During the process of the threaded section 703 being screwed into the clamping arm 401 and being threadedly connected to the clamping arm 401, the movable section 702 is screwed into the central through hole, and the spiral rib 704 is squeezed by the screwing and is elastically deformed away from the spiraling direction of the spiral rib 704.

[0057] In this way, as the threaded section 703 is screwed into the clamping arm 401 to achieve a threaded connection, the movable section 702 is also screwed into the through hole. During the screwing process, the spiral rib 704 is squeezed and deformed, and elastically deformed away from the spiraling direction of the spiral rib 704. This allows the movable section 702 and the end plate 201 to achieve elastic compression and elastic fixation. Furthermore, the spiral rib 704 is in a state of compression deformation, which makes the connection between the threaded section 703 and the clamping arm 401 more stable. The movable section 702 and the end plate 201 have elastic buffering capacity, so that during the process of the transmission frame 400 driving the secondary servo motor 200 to rotate, elastic buffering can be achieved, avoiding large vibrations to the flight shape of the UAV.

[0058] In addition, the middle part of the spiral rib 704 is movably arranged with the movable section 702, and the end of the spiral rib 704 is fixedly connected with the movable section 702, so that the spiral rib 704 has a greater elastic deformation capacity and will not exhibit the phenomenon of overall twisting and clumping.

[0059] In this embodiment, the spiral rib 704 has multiple fixed positions 705 in the middle. The fixed positions 705 are fixedly connected to the movable section 702. The multiple fixed positions 705 are arranged sequentially at intervals along the spiral direction of the spiral rib 704. The spiral rib 704 has a free section located between adjacent fixed positions 705.

[0060] During the elastic deformation of the spiral rib 704, the fixed position 705 and the movable section 702 remain fixed, while the free section is subjected to spiral compression and elastically deforms away from the spiral direction of the spiral rib 704.

[0061] In this way, when the spiral rib 704 is subjected to extrusion elastic deformation, the free section undergoes extrusion deformation, and under the restriction of the fixed position 705, the phenomenon of the entire spiral rib 704 twisting and clumping as a whole is avoided.

[0062] In this embodiment, one end of the transmission frame 400 has a transmission sleeve 403, and the transmission sleeve 403 has a transmission hole 406. The first-stage output shaft passes through the transmission hole 406 and is connected to the transmission sleeve 403 as a whole. The inner sidewall of the transmission hole 406 is recessed outward to form multiple longitudinal grooves. The multiple longitudinal grooves are arranged around the circumference of the transmission hole 406 at intervals.

[0063] The longitudinal groove is filled with elastic material to form longitudinal elastic strips 4032; the primary output shaft abuts against the inner wall of the transmission hole 406, and the multiple longitudinal elastic strips 4032 are compressed and deformed towards the longitudinal groove by the pressure of the primary output shaft. The multiple longitudinal elastic strips 4032 press against the primary output shaft, and axially elastically fix the primary output shaft and the transmission sleeve 403.

[0064] In this way, multiple longitudinal elastic strips 4032 press against the primary transmission shaft, axially elastically fixing the primary transmission shaft so as to achieve an elastic connection between the primary transmission shaft and the transmission frame 400 and realize the function of elastic transmission. When the primary transmission shaft rotates, the multiple longitudinal elastic strips 4032 elastically compress and drive the transmission frame 400 to swing, thereby achieving the functions of shock absorption and elastic buffering.

[0065] In this embodiment, the inner wall of the transmission hole 406 has a plurality of adjacent segments 4031, which are arranged around the transmission hole 406 at circumferential intervals and are located between adjacent longitudinal grooves.

[0066] Adjacent segments 4031 have recessed transverse grooves filled with elastic material to form transverse elastic strips 4033. Multiple transverse elastic strips 4033 are compressed and deformed towards the transverse grooves by the pressure of the primary output shaft. Multiple transverse elastic strips 4033 press against the primary output shaft, thus circumferentially and elastically fixing the primary output shaft and the transmission sleeve 403.

[0067] By arranging multiple transverse elastic strips 4033, the primary output shaft can be circumferentially pressed to achieve circumferential elastic fixation of the primary output shaft. In this way, the primary output shaft can achieve circumferential elastic buffering and axial elastic buffering during the swinging process of the transmission frame 400, thereby avoiding large vibrations in the transmission frame 400 during the swinging process.

[0068] In this embodiment, the antenna 300 has a connecting section 301, and the connecting section 301 has an end ring 600, which is arranged around the circumference of the connecting section 301; the mounting bracket 500 is bent, and the mounting bracket 500 includes a mounting sleeve 503 and a mounting plate 501. The mounting plate 501 and the mounting sleeve 503 are arranged in a bent manner. The mounting sleeve 503 is sleeved on the secondary output shaft and is fixedly connected to the secondary output shaft.

[0069] The mounting plate 501 has a central hole 502, through which the connecting section 301 moves movably; the end ring 600 has a plurality of elastic shafts 603 protruding, which are arranged around the connecting section 301 at circumferential intervals; the mounting plate 501 has a plurality of circumferential holes 505, which are arranged around the central hole 502 at circumferential intervals, through which the plurality of elastic shafts 603 pass respectively.

[0070] A nut 601 is provided on the connecting section 301, and the nut 601 is threadedly connected to the connecting section 301; the nut 601 has a pressing end face 606 facing the mounting plate 501, and the pressing end face 606 is recessed inward to form an annular groove; one end of the elastic shaft 603 is fixedly connected to the end ring 600 to form a fixed end, and the other end of the elastic shaft 603 is movably placed in the annular groove to form a movable end;

[0071] Nut 601 is screwed toward mounting plate 501 to compress and deform multiple elastic shafts 603, increasing the diameter of elastic shafts 603. Elastic shafts 603 press against the inner wall of circumferential hole 505. Elastic shafts 603 are deformed by the opposing compression of nut 601 and end ring 600. Elastic gaps 602 are formed between end ring 600 and mounting plate 501, and between mounting plate 501 and nut 601.

[0072] In this way, multiple elastic shafts 603 pass through the circumferential hole 505, with the fixed end abutting on the end ring and the movable end embedded in the annular groove. When the elastic shafts 603 are squeezed, they undergo compression deformation, so that the mounting plate 501 is elastically clamped. The multiple elastic shafts 603 are arranged around the circumferential hole 502 at intervals, so that the entire mounting plate 501 can be elastically clamped and fixed in the entire circumference. When the mounting plate 501 drives the antenna 300 to rotate, it can achieve elastic rotation, which can play a role in shock absorption and buffering.

[0073] In this embodiment, the inner wall of the circumferential hole 505 is recessed outward to form a circumferential annular groove 506, which is arranged around the circumference of the circumferential hole 505. When the elastic shaft 603 is squeezed and deformed, the middle part of the elastic shaft 603 protrudes towards the circumferential annular groove 506 to form an embedded ring embedded in the circumferential annular groove 506.

[0074] In this way, when the elastic shaft 603 is squeezed and deformed, it will be embedded in the circumferential groove 506, so that the elastic shaft 603 and the mounting plate 501 can achieve more elastic connections and improve the elastic damping effect of the elastic shaft 603.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
