Description

Technical Field

[0001] This utility model belongs to the field of UAV cable and antenna installation technology, and in particular relates to an installation assembly for an external UAV antenna and its matching transmission cable. Background Technology

[0002] With the widespread application of drone technology, antennas and supporting transmission cables are key components for ensuring stable signal transmission. The performance of their installation structure is directly related to flight safety, especially the problems of asynchronous installation of antennas and supporting transmission cables in external parts of drones, messy cable layout, and cable failure caused by vibration.

[0003] Traditional antenna brackets in the existing technology are mostly designed with fixed length or specific shape, which makes it difficult to adapt to the body structure of different models of drones, and cannot flexibly adjust the distance and angle between the antenna and the body, which easily leads to signal blind spots in actual use and makes it difficult to balance anti-interference ability and aerodynamic performance.

[0004] Secondly, disassembly and maintenance are inconvenient. Most of them use adhesive or complex rigid connection structures. When replacing the antenna or repairing the feeder, it is often necessary to disassemble the fuselage with special tools, which is inefficient. In addition, some quick-release structures lack effective anti-loosening design. Vibration during flight can easily lead to accidental unlocking, which poses a safety hazard.

[0005] In addition, existing structures often fix the antenna directly inside the fuselage or near the gimbal, lacking an effective buffering mechanism. The high-frequency vibrations generated by the motor operation and flight are directly transmitted to the antenna and the supporting transmission cable, which can easily cause loosening of the joints, fatigue of the solder joints, or even displacement of the antenna phase center, seriously affecting the service life of the equipment and the stability of signal reception. Utility Model Content

[0006] In view of this, the present invention aims to provide an external antenna for unmanned aerial vehicles (UAVs) and a matching transmission cable installation assembly to solve the problem that existing external antennas and matching transmission cables for UAVs lack an effective buffering mechanism, which causes high-frequency vibrations generated by the motor and body during flight to be directly transmitted to the antenna body, and the vibrations can easily lead to cable failures and affect the flight of the UAV.

[0007] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0008] An external antenna and matching transmission cable mounting assembly for a drone, characterized in that it includes:

[0009] Fixed top mount, fixed base and shock-absorbing connectors;

[0010] One end of the fixed top seat is formed with an installation connection end, and the other end is formed with a top seat shock absorption connection end;

[0011] The fixed base includes a base body and a clamping connection part. The clamping connection part is connected to the base body and is used to clamp and fix the external antenna of the UAV and its matching transmission cable.

[0012] The base body and the top seat shock-absorbing connection end are detachably connected through the shock-absorbing connector, and the two ends of the shock-absorbing connector form elastic abutments with the mating surfaces of the base body and the top seat shock-absorbing connection end, respectively.

[0013] Furthermore, shock-absorbing connection holes are correspondingly provided on the base body and the shock-absorbing connection end of the top seat.

[0014] Furthermore, the top seat damping connection end includes:

[0015] Two sets of symmetrically arranged arc-shaped connecting bodies;

[0016] The shock-absorbing connection hole is opened at the end of the arc-shaped connector. Each set of arc-shaped connectors is connected to the base body through a fixing body, so that a hollow area is formed between the two sets of fixing bodies.

[0017] Furthermore, one end of the mounting connection end is constructed with an arc-shaped bend, and the other end is constructed with an open opening formed by the connection of a circular section and a rectangular section.

[0018] The mounting connection end is provided with mounting and fixing holes.

[0019] Furthermore, the base body has an I-shaped structure, the thickness of the four end regions of the I-shaped structure is less than the thickness of the middle region, and the end regions are provided with the shock-absorbing connection holes.

[0020] Furthermore, the clamping connection includes:

[0021] Two sets of semi-rings, one end of each set of semi-rings is connected to the base body and encloses it to form a closed end;

[0022] The other ends of the two sets of semi-rings are correspondingly enclosed to form a clamping joint;

[0023] The two sets of semi-rings are connected by threaded connections at the adjacent clamping joints via connecting pieces;

[0024] The axis of the threaded connection is arranged perpendicular to the central axis of the semi-ring.

[0025] Furthermore, the shock-absorbing connector includes:

[0026] Connecting column;

[0027] The elastic module is provided at both ends and in the middle of the connecting column;

[0028] The diameter of the connecting post is smaller than the diameter of the elastic module;

[0029] The diameter of the connecting column is adapted to the diameter of the shock-absorbing connecting hole;

[0030] An interlocking gap is formed between the upper and lower adjacent elastic modules;

[0031] The width of the insertion gap is adapted to the thickness of the top seat shock-absorbing connection end or the base seat body.

[0032] Furthermore, the elastic module is a silicone pad;

[0033] The elastic module includes an end elastic module and a center elastic module;

[0034] The central elastic module is located radially in the middle of the connecting column;

[0035] The end elastic modules are disposed at both ends of the connecting column, and the end elastic modules are configured with a bowl-shaped flange towards the central elastic module so that the end elastic modules can be squeezed into the corresponding shock-absorbing connecting holes.

[0036] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0037] Firstly, this technical solution enables convenient and rapid installation. By utilizing the matching structure of the fixed top mount and the fixed base, along with shock-absorbing connectors, the antenna assembly can be quickly locked and disassembled on the drone body without the need for any special tools. This greatly reduces maintenance costs, improves installation efficiency, and especially standardizes cable routing, preventing cable tangling and loosening, and reducing the probability of cable connector failure.

[0038] Secondly, the elastic module design in the shock-absorbing connector effectively isolates and absorbs the vibration generated during the flight of the drone, preventing the vibration from being directly transmitted to the antenna body, thereby protecting the precision components inside the antenna, extending the service life of the equipment, and ensuring the continuous and stable signal transmission.

[0039] Thirdly, this technical solution can ensure a stable connection while automatically compensating for installation gaps through elastic contact, preventing loosening caused by vibration, thus achieving a balance between convenience and stability. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0060] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0061] This utility model aims to provide an external antenna for unmanned aerial vehicles (UAVs) and a matching transmission cable installation assembly to solve the problem that existing external antennas and matching transmission cables for UAVs lack an effective buffering mechanism, causing high-frequency vibrations generated by the motor and fuselage during flight to be directly transmitted to the antenna body. This vibration can easily lead to cable failure and affect the flight of the UAV; for example, the cables are prone to tangling and loosening, and the vibration of the fuselage can easily cause the cable connectors to fall off or have poor contact, affecting signal transmission.

[0062] External antennas include, for example: image transmission antenna, remote control signal antenna, GPS antenna, and range extender antenna; external cables include, for example: power supply cable, image transmission cable, video cable, flight control debugging cable, and load control cable.

[0063] Please see Figure 1 , 2 As shown, the UAV external antenna and its supporting transmission cable mounting assembly includes a fixed top mount 10, a fixed base 20, and a shock-absorbing connector 30; one end of the fixed top mount 10 is formed with a mounting connection end 101, and the other end is formed with a top mount shock-absorbing connection end 102.

[0064] The fixed base 20 includes a base body 201 and a clamping connection part 202. The clamping connection part 202 is connected to the base body 201 and is used to clamp and fix the external antenna of the UAV and its supporting transmission cable, presenting an independent clamping design to handle the external wiring of the UAV separately.

[0065] The base 201 and the top shock-absorbing connection 102 are detachably connected by the shock-absorbing connector 30. The two ends of the shock-absorbing connector 30 form elastic abutments with the mating surfaces of the base 201 and the top shock-absorbing connection 102, respectively. At the same time, the elastic module can flexibly adjust the buffering force according to the vibration intensity to prevent vibration from being transmitted to the external antenna and the matching transmission cable body, thereby reducing the occurrence of failures.

[0066] In one specific embodiment, please refer to Figure 2 , Figure 5 As shown, shock-absorbing connection holes 103 are correspondingly provided on the base body 201 and the top seat shock-absorbing connection end 102;

[0068] In one specific embodiment, please refer to Figure 3 As shown, the top seat shock-absorbing connection end 102 includes: two sets of symmetrically arranged arc-shaped connecting bodies 11; shock-absorbing connection holes 103 are opened at the ends of the arc-shaped connecting bodies 11, and each set of arc-shaped connecting bodies 11 is connected to the base body 201 through a fixing body 12, so that a hollow area is formed between the two sets of fixing bodies 12.

[0069] The arc-shaped connector can be manufactured using a one-piece molding process. The hollow area can be used to store antenna lines, preventing them from getting tangled, and also facilitating later maintenance, thus improving the overall ease of installation.

[0070] In one specific embodiment, please refer to Figure 2As shown, one end of the mounting connection end 101 is constructed with an arc-shaped bend 110, and the other end is constructed with an open opening 120 formed by connecting a circular section and a rectangular section; the mounting connection end 101 is provided with a mounting and fixing hole 104.

[0071] The curved section can serve as an identification component for installation, the open opening can guide the antenna to be quickly embedded and installed, and the mounting holes can accommodate fixing bolts of different sizes, improving the versatility of the device and facilitating quick fixing.

[0072] In one specific embodiment, please refer to Figure 4 As shown, the base body 201 has an I-shaped structure. The thickness of the four end regions of the I-shaped structure is less than the thickness of the middle region, and the end regions are provided with shock-absorbing connection holes 103.

[0073] The I-beam structure can reduce the overall weight while ensuring structural strength, which is suitable for the lightweight requirements of drones. The thinning design at the ends can better fit with the shock-absorbing connector 30 and improve the cushioning effect.

[0074] In one specific embodiment, please refer to Figure 6 As shown, the clamping connection part 202 includes: two sets of semi-rings 210, one end of the two sets of semi-rings 210 is connected to the base body 201, and the other end is correspondingly enclosed to form a clamping joint 211; the two sets of semi-rings 210 are connected to threaded connection parts 213 by connecting pieces 212 at the positions of adjacent clamping joints 211; the axis of the threaded connection part 213 is arranged perpendicular to the central axis of the semi-rings 210.

[0075] The threaded connection can be quickly locked by threaded connection of locking bolts and nuts without additional tools, which is convenient for on-site installation and adjustment. At the same time, the connecting piece can enhance the structural stability and make it easier to process and manufacture the way that the axis of the threaded connection 213 is arranged perpendicular to the central axis of the semi-ring 210.

[0076] In one specific embodiment, please refer to Figure 7 As shown, the shock-absorbing connector 30 includes: a connecting post 310; elastic modules 301 are provided at both ends and in the middle of the connecting post 310; the diameter of the connecting post 310 is smaller than the diameter of the elastic modules 301; the diameter of the connecting post 310 is adapted to the diameter of the shock-absorbing connecting hole 103; a snap-fit ​​gap 302 is formed between the upper and lower adjacent elastic modules 301; the width of the snap-fit ​​gap 302 is adapted to the thickness of the top seat shock-absorbing connecting end 102 or the base seat 201, and the snap-fit ​​gap can be flexibly adjusted according to the actual installation requirements to ensure that the elastic modules fit tightly with the base and top seat, and fully exert the buffering effect.

[0077] For a more specific embodiment, please refer to Figure 8As shown, the elastic module 301 is a silicone pad; the elastic module 301 includes an end elastic module 320 and a center elastic module 330; the center elastic module 330 is located at the radial position in the middle of the connecting post 310; the end elastic modules 320 are located at both ends of the connecting post 310, and the end elastic modules 320 are constructed with a bowl-shaped flange in the direction of the center elastic module 330, so that the end elastic modules 320 can be squeezed into the corresponding shock-absorbing connecting hole 103.

[0078] The silicone elastic module has good elastic recovery ability. The cup-shaped flange can fit tightly against the outer edge of the shock-absorbing connection hole 103 to enhance the sealing performance. At the same time, it is easy to assemble and disassemble. The elastic module can be replaced separately in the future to reduce maintenance costs.
