Description

Technical Field

[0001] This utility model relates to the field of drone payload mounting technology, specifically to an adjustable drone payload mount. Background Technology

[0002] Drone technology has developed rapidly in recent years, and its application scenarios have expanded from the initial military field to all aspects of civilian and industrial fields. Drones often need to carry different types of payloads, such as high-precision mapping cameras, multispectral sensors, logistics boxes, communication relay equipment, and special detection equipment arrays.

[0003] A large number of non-standardized, dedicated drones exist on the market, typically optimized for specific missions or payloads. However, this specialization leads to poor payload rack compatibility. The vast majority of existing drone payload racks are custom-designed for payloads of specific sizes and shapes. When a different type of payload needs to be replaced, a completely new rack must often be designed, manufactured, and installed to match the current payload dimensions, resulting in increased costs and reduced efficiency.

[0004] Therefore, how to provide an adjustable drone payload mount to solve the defects of existing drone payload mounting structures is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] To address this issue, this invention provides an adjustable drone payload mount to solve the problem of poor compatibility in existing technologies, where payload mounts need to be custom-made for payloads of specific sizes and shapes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses an adjustable unmanned aerial vehicle (UAV) payload mount, comprising:

[0008] A fixed plate has a pair of drive mechanisms mounted on its top surface, and slide rail assemblies are mounted in pairs at both ends of its bottom surface.

[0009] Adjustment mechanisms are arranged in pairs and installed on the bottom surface of the fixed plate. Each adjustment mechanism is provided with a longitudinal moving end and a pair of transverse moving ends. The longitudinal moving end of the adjustment mechanism is drivenly connected to the drive mechanism, and both transverse moving ends of the adjustment mechanism are slidably connected to the slide rail assembly.

[0010] The load supports are arranged in pairs, with each end mounted on one of the two adjustment mechanisms. The pairs of load supports are arranged in parallel between the adjustment mechanisms.

[0011] In one possible implementation, the adjustment mechanism includes:

[0012] The hinge assembly is Y-shaped, with one end being drively connected to the side wall of the drive mechanism;

[0013] The slider is symmetrically arranged and rotatably connected to one end of the Y-shaped fork of the hinge assembly.

[0014] In one possible implementation, the hinge assembly includes:

[0015] One end of the drive rod is connected to the transmission on the side wall of the drive mechanism, and the other end of the drive rod is rotatably connected to a connecting rod;

[0016] The deflector block has one side of its outer wall rotatably connected to one end of the connecting rod in the vertical direction, and two sides of its outer wall rotatably connected to hinge rods in the horizontal direction. One end of each hinge rod is rotatably connected to the slider.

[0017] In one possible implementation, a limiting component is also included, with one end mounted on the bottom surface of the fixed plate and the other end of the limiting component slidably connected to the hinge component.

[0018] In one possible implementation, the limiting component includes:

[0019] The guide rod is sleeved inside the deflector block;

[0020] The abutment plate is installed at the end of the guide rod facing the slide rail assembly.

[0021] In one possible implementation, the slide rail assembly includes:

[0022] Baffles, symmetrically arranged, are installed on the bottom surface of the fixed plate;

[0023] A sliding rod is installed between the two baffles, and the sliding rod is slidably connected to the slider.

[0025] In one possible implementation, the fixing plate includes:

[0026] The first fixed plate has a through groove on its surface, and the drive rod is connected to the drive mechanism through the through groove.

[0027] The second fixing plate is installed on the bottom surface of the first fixing plate.

[0028] In one possible implementation, the abutment plate is mounted on the bottom surface of the fixing plate.

[0029] This utility model has the following advantages:

[0030] This invention completely solves the fatal flaws of existing non-standard UAV payload mounts—poor compatibility and inability to adapt to different centers of gravity—through a two-dimensional adjustment mechanism: lateral adjustment (drive mechanism, adjustment mechanism, and slide rail assembly) and longitudinal multi-position adjustment (load bracket with through holes). It significantly improves the versatility of UAV payload mounts, enabling them to adapt to various payloads of different sizes and centers of gravity, greatly reducing the cost and time required for repeated design, customization, and replacement of mounts due to payload changes, while ensuring the flight stability of the UAV when carrying different payloads.

Detailed Implementation

[0040] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] Please refer to Figures 1-6 The present invention discloses an adjustable UAV payload mount, which consists of five parts, as follows: Figure 1The device includes a fixed plate 1, adjusting mechanisms 2, slide rail assemblies 3, load supports 4, and drive mechanisms 5. A pair of drive mechanisms 5 are mounted on the top surface of the fixed plate 1, and a pair of slide rail assemblies 3 are mounted on both ends of the bottom surface of the fixed plate 1. Adjusting mechanisms 2 are arranged in pairs and mounted on the bottom surface of the fixed plate 1. Each adjusting mechanism 2 has a longitudinal moving end and a pair of lateral moving ends. The longitudinal moving end of the adjusting mechanism 2 is driven by the drive mechanism 5, and both lateral moving ends of the adjusting mechanism 2 are slidably connected to the slide rail assemblies 3. Load supports 4 are arranged in pairs, with each end mounted on one of the two adjusting mechanisms 2, and the pairs of load supports 4 are arranged parallel to each other between the adjusting mechanisms 2. In use, the fixed plate 1 is first installed on the belly of the drone. When loads of different sizes or centers of gravity, such as surveying equipment or logistics boxes, need to be mounted, the drone flight control system commands the drive mechanism 5 to move. The drive mechanism 5 drives the linkage assembly of the adjustment mechanism 2 (including: drive rod 212, connecting rod 213, directional block 214, and hinge rod 211), pushing the symmetrically arranged slider 22 to slide synchronously and in opposite directions on the slide bar 31 of the slide rail assembly 3. This adjusts the lateral spacing between the paired load supports 4 mounted on the adjustment mechanism 2 at both ends, precisely matching the width of the load. Simultaneously, based on the length of the load and the most critical center of gravity position requirements, several through holes 41 along the length of the load support 4 are selected for fixed installation. By longitudinally adjusting the fixed point position of the load on the support, the overall center of gravity of the load is ensured to match the center of gravity requirements of the drone, guaranteeing flight stability. When changing the load, only the above steps of electronically adjusting the lateral spacing and manually selecting the longitudinal fixing hole position need to be repeated; there is no need to replace the entire mounting bracket, significantly improving the convenience and efficiency of adapting to different loads and reducing costs.

[0042] In a specific embodiment, such as Figures 2-3 The adjustment mechanism 2 includes a hinge assembly 21 and a slider 22. The hinge assembly 21 is Y-shaped, with one end connected to the side wall of the drive mechanism 5. The slider 22 is symmetrically arranged and rotatably connected to one end of the Y-shaped fork of the hinge assembly 21. The hinge assembly 21 receives power, changes the direction of motion, and symmetrically distributes the power. The slider 22 converts the power into precise linear motion along the slide rail and directly drives the load support to move. Together, they realize the core function of adjusting the lateral dimension by having the servo drive the slider to move through the connecting rod.

[0043] In a specific embodiment, such as Figures 2-3 It also includes a limiting component 23, one end of which is mounted on the bottom surface of the fixed plate 1, and the other end of the limiting component 23 is slidably connected to the hinge component 21. The limiting component 23 provides stability and guidance for the entire transmission chain by constraining the movement trajectory of the slider 22 and providing a guide track for the hinge component 21.

[0044] In a specific embodiment, such as Figure 4 The hinge assembly 21 includes a hinge rod 211, a drive rod 212, a connecting rod 213, and a deflector block 214. One end of the drive rod 212 is connected to the side wall of the drive mechanism 5, and the other end of the drive rod 212 is rotatably connected to the connecting rod 213. One side of the deflector block 214 in the vertical direction is rotatably connected to one end of the connecting rod 213, and the two sides of the deflector block 214 in the horizontal direction are respectively rotatably connected to the hinge rod 211. One end of the hinge rod 211 is rotatably connected to the slider 22. In the process of achieving lateral dimension adjustment, the drive rod 212, as the power transmission end, directly receives the driving force from the drive mechanism 5 and transmits the motion to the connecting rod 213. The connecting rod 213 transmits the motion to the deflector block 214. At this time, the guide rod 231 of the limiting component 23 strictly constrains the deflector block 214, so that it can only make precise linear movements in a predetermined direction. While the deflector block 214 is moving in a straight line, the longitudinal linear motion is converted into lateral thrust or pull through the hinge rod 211 rotatably connected to its horizontal sides. The hinge rod 211 then drives the slider 22 rotatably connected to its end, so that the slider 22 performs the key lateral linear sliding on the slide rod 31 of the slide rail component 3. Finally, the synchronous movement of the symmetrically arranged sliders 22 directly drives the load bracket 4 to change the spacing, thereby realizing the adjustment of the bracket width.

[0045] In a specific embodiment, such as Figure 5 The limiting component 23 includes a guide rod 231 and an abutment plate 232. The guide rod 231 is sleeved inside the deflector block 214, and the abutment plate 232 is installed at the end of the guide rod 231 facing the slide rail assembly 3. The guide rod 231 is directly sleeved in the reserved hole of the deflector block 214 of the hinge assembly 21. Its core function is to strictly constrain the movement trajectory of the deflector block 214 when it moves, forcing the deflector block 214 to make precise and stable linear movements only along the axial direction of the guide rod 231. This effectively prevents the deflector block 214 from deviating, rotating, or shaking during transmission, thereby ensuring the reliability and directional accuracy of power transmission. The main function of the abutment plate 232 is to act as a physical travel limiter for the linear motion of the deflector block 214 and the slider 22. When the slider 22 slides towards each other and reaches the abutment plate 232, it abuts, thereby limiting the displacement distance of the slider 22. When the deflector block 214 moves to the end position of the guide rod 231, it abuts against the abutment plate 232, thereby preventing the deflector block 214 from dislodging from the guide rod 231. The three work together to protect the safety of the mechanism and define the maximum and minimum range of lateral adjustment, ensuring that the lateral dimension adjustment process is smooth, reliable and controllable.

[0046] In a specific embodiment, such as Figure 5The slide rail assembly 3 includes a slide rod 31 and baffles 32. The baffles 32 are symmetrically arranged and installed on the bottom surface of the fixed plate 1. The slide rod 31 is installed between the two baffles 32, and a slider 22 is slidably connected to the slide rod 31. The slide rod 31, as a guide component, has its two ends reliably fixed between the paired baffles 32, providing a rigid, low-friction linear motion track for the slider 22. The slider 22 slides directly on the slide rod 31, and its core function is to precisely guide and support the slider 22 for smooth and stable lateral linear motion, bearing the radial loads from the slider 22, the load support 4, and the load itself. The baffles 32 are firmly installed on the bottom surface of the fixed plate 1, and their main function is to reliably fix and support the slide rod 31 axially, preventing axial movement or detachment of the slide rod 31 during operation, and ensuring the overall stability of the slide rail structure. Working together, the two provide a stable, precise, and low-resistance motion foundation for the slider 22, and are the key support structure for realizing the lateral position adjustment of the load support 4 and ensuring its load-bearing capacity.

[0047] In a specific embodiment, such as Figure 3 The load support 4 has several through holes 41. The design of the through holes 41 is the core of this utility model to achieve flexible adjustment. By selecting multiple hole positions, it solves the two key problems of adapting to the load length and matching the center of gravity of the UAV, which significantly improves the compatibility and safety of the rack for different loads.

[0048] In a specific embodiment, such as Figure 6 The fixing plate 1 includes a first fixing plate 11, a second fixing plate 12, and a through groove 13. The first fixing plate 11 has a through groove 13 on its surface, through which the drive rod 212 is connected to the drive mechanism 5. The second fixing plate 12 is installed on the bottom surface of the first fixing plate 11. The first fixing plate 11 serves as the top support platform, with the drive mechanism 5 directly mounted on its top surface. The through groove 13 on its surface provides a downward passage for the output shaft of the drive mechanism 5, ensuring that power can be smoothly transmitted to the adjustment mechanism 2 below. The second fixing plate 12 is firmly installed on the bottom surface of the first fixing plate 11. Its function is to enhance the overall structural rigidity and load-bearing strength of the fixing plate to cope with the load during the adjustment process, ensuring reliable power transmission and the stable operation of the hanger structure.

[0049] In a specific embodiment, such as Figure 5The abutment plate 232 is mounted on the bottom surface of the fixed plate 1. Its function is to work in conjunction with the guide rod 231. On the one hand, it serves as a reliable mounting base and fixing point for the end of the guide rod 231, ensuring the stable positioning of the guide rod 231. On the other hand, it serves as the end limit of the linear motion stroke of the deflector block 214. When the deflector block 214 moves to its end along the guide rod 231 during the transmission of the hinge assembly 21, it will directly abut against the abutment plate 232, thereby precisely limiting the maximum displacement range of the deflector block 214 and preventing it from dislodging from the guide rod or overtraveling. At the same time, the abutment plate 232 directly limits the displacement range of the deflector block 214, thereby protecting the safety of the mechanism and defining the range of lateral adjustment.

[0050] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
