Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) equipment technology, and more specifically, to a support and adjustment device for mounting mission payloads on a UAV platform, particularly a UAV launcher mounting base suitable for carrying net launchers and other devices with strong impact loads, and whose pitch angle can be manually preset. Background Technology

[0002] With the rapid development of drone technology, its application in civilian and quasi-military fields is constantly deepening. Especially in tasks such as police security, key area patrols, and counter-terrorism, drones have become indispensable technical equipment. To address the increasingly serious threat of "black flights" (i.e., unauthorized drone flights), developing efficient and reliable drone countermeasure systems has become an important issue in maintaining low-altitude security. Among numerous countermeasures, utilizing "Hunter" drones equipped with physical interception devices such as net launchers has become a favored active defense solution due to its advantages of complete target capture and easy traceability.

[0003] However, a successful drone countermeasure system depends not only on the performance of the drone platform itself and the power of the launcher, but also, to a large extent, on the way the launcher is mounted and aimed at the drone. An ideal mount should possess multiple advantages, including structural stability, flexible adjustment, lightweight reliability, and controllable cost. Looking at existing technologies, mainstream mounting solutions struggle to simultaneously meet these requirements, primarily due to the following two insurmountable contradictions and defects: The first type is the rigid fixed installation scheme. This scheme directly fixes the launcher to the UAV fuselage using a non-adjustable bracket. Its advantages are simple structure, light weight, and extremely low cost. However, its disadvantages are equally fatal: the launch angle is completely fixed. In actual missions, the altitude difference and relative distance between friendly and enemy UAVs are dynamic, and a fixed-angle launcher cannot adapt to these changes. The operator's only aiming method is to manipulate the entire UAV platform to perform violent pitch changes, using the aircraft's attitude to compensate for the non-adjustable launch angle. This aiming method not only greatly increases the complexity of the pilot's operation, but also, during high-speed chases, frequent maneuvers severely affect flight stability and energy efficiency, significantly reducing the probability of a hit and greatly diminishing its effectiveness in actual combat.

[0004] The second type is the active motorized gimbal solution. To solve the aiming challenges of fixed installations, high-end systems employ two- or three-axis motorized gimbals integrating servo motors, reducers, and controllers. This solution allows operators to adjust the launcher's pitch and yaw angles in real time and with precision via remote control, separating "platform flight" from "payload aiming," greatly improving the convenience and accuracy of aiming. However, the complexity of this technical approach also brings inherent and difficult-to-eradicate drawbacks. First, the complex structure raises concerns about reliability. The motorized gimbal contains numerous electronic components and precision mechanical transmission parts. In harsh outdoor environments, electronic components are susceptible to moisture, electromagnetic interference, or vibration failure. More critically, the net launcher generates a huge, instantaneous impact load (recoil) at the moment of launch. This impact force poses a severe test to the precision reduction gearbox, easily leading to gear breakage, increased transmission clearance (resulting in play), or motor "step loss," thus seriously affecting aiming accuracy and device lifespan. Second, it is costly and heavy. A high-performance servo gimbal system can account for a significant portion of the total payload cost, making it uneconomical for police and security applications requiring mass deployment. Furthermore, the added weight of components such as motors, reducers, and metal casings significantly increases the drone's takeoff weight, directly sacrificing valuable endurance and payload capacity. Finally, maintenance is difficult. If the motorized gimbal malfunctions, repairs typically require specialized equipment and technicians; on-site quick repairs are virtually impossible, which is unacceptable in time-sensitive security missions. Utility Model Content

[0005] The main purpose of this utility model is to address the technical shortcomings of existing UAV launcher mounting methods, such as complex structure, high cost, heavy weight, poor reliability, or fixed angle and inconvenient aiming, by providing an adjustable pitch angle mounting base for UAV launchers that is extremely simple in structure, completely reliable in operation, low in cost, lightweight, and allows for convenient preset adjustment of pitch angle.

[0006] To achieve the above objectives, the core technical solution adopted by this utility model is as follows: This utility model provides the following technical solution: an adjustable pitch angle mounting base for an unmanned aerial vehicle (UAV) launcher, comprising: The base is designed to connect and securely attach to the drone's body. The transmitter bracket is designed to support and secure the transmitter. The front hinge can rotatably connect the front end of the transmitter bracket to the base so that the transmitter bracket can pitch about the front hinge. An adjustable link, one end of which is rotatably hinged to the launcher bracket and the other end of which is connected to the base, is used to support the launcher bracket; Angle locking mechanism: The angle locking mechanism can detachably fix the adjustable link to the base to lock the pitch angle of the launcher bracket at a preset position. The angle locking mechanism includes multiple adjustment holes spaced apart along the length of the adjustable link, and a positioning hole on the base for alignment with any of the adjustment holes. By inserting a positioning element into the aligned adjustment hole and positioning pin hole, the pitch angle of the transmitter bracket can be locked.

[0007] Furthermore, the upper surface of the transmitter bracket is provided with a V-shaped slot for supporting the transmitter, and the distance between the two sides of the V-shaped slot gradually decreases along the recoil direction opposite to the launch direction of the transmitter.

[0008] Furthermore, the adjustable link is an arc-shaped link, with multiple adjustment holes distributed along the arc path of the arc-shaped link.

[0009] Furthermore, the mounting base includes two sets of symmetrically arranged adjustable linkages and angle locking mechanisms, which are located on both sides of the transmitter bracket.

[0010] Furthermore, the front hinge portion includes a pair of first hinge seats fixed to the base and a second hinge seat fixed to the front end of the transmitter bracket. The second hinge seat is disposed between the pair of first hinge seats and passes coaxially through the first and second hinge seats via a pivot.

[0011] Furthermore, it also includes a positioning seat, which is fixed to the outside of the upper surface of the base, and the positioning pin hole is opened on the positioning seat.

[0012] Furthermore, the end of the adjustable link away from the angle locking mechanism is rotatably connected to the lower surface of the transmitter bracket via a third hinge seat.

[0013] Furthermore, the base is a flat plate structure with multiple mounting holes for fixing it to the drone body.

[0014] Furthermore, a drone is also provided, including a fuselage, a transmitter, and an adjustable pitch angle mount for the drone-borne transmitter as described above, wherein the flight unit and the transmitter are connected via the adjustable pitch angle mount for the drone-borne transmitter.

[0015] Compared with the prior art, the beneficial effects of this utility model are significant and multifaceted: 1. High Structural Strength and Reliability: The core of this solution is a rigid locking mechanism based on a linkage-pin. Once locked by the pin, the launcher bracket, adjustable linkage, and base form a stable triangular or quadrilateral truss structure. This purely mechanical rigid connection can rapidly and evenly transmit the enormous impact force generated during launch to the UAV fuselage, without any displacement or deformation of the structure itself. Compared to electric gimbals that rely on gear meshing, this solution fundamentally eliminates problems such as transmission failure and accuracy reduction caused by impact, resulting in an order-of-magnitude improvement in reliability. It ensures that the launch angle remains accurate even under continuous, high-intensity use.

[0016] 2. Cost Advantages and Lightweight Features: The design philosophy of this solution is "less is more," replacing the existing expensive and bulky "motor + reducer + controller" system with a clever mechanical structure. The overall structure consists of only a few machined metal parts and standard fasteners, resulting in extremely low material and manufacturing costs. Simultaneously, the significant reduction in the number of components and the optimized structural design make this mounting base much lighter than a motorized gimbal with equivalent load-bearing capacity. For drone platforms, this translates to longer flight time, faster maneuverability, or the ability to carry more additional equipment, thus improving the overall efficiency and economy of the drone platform.

[0017] 3. Intuitive and convenient operation, strong mission adaptability: This solution provides a flexible adjustment mode that can be pre-installed before a mission. Operators can predict the airspace where the target may appear based on intelligence information or the situation on site. Before the UAV takes off, angle switching and locking can be completed within seconds using only manual operation or simple tools, without the need for specialized tools or complex calibrations. Multiple angle selections are sufficient to cover most combat scenarios, maximizing the system's tactical flexibility while maintaining structural simplicity.

[0018] 4. Enhanced safety: By designing the V-shaped slot on the launcher bracket as a tapered structure that converges along the recoil direction, the recoil force generated during launch is cleverly utilized and converted into additional clamping force, forming a wedge-shaped self-locking effect that becomes more stable with each impact. This design fundamentally eliminates the risk of the launcher loosening or falling off due to severe impact, greatly improving the safety of the entire system. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings: To make the objectives, technical solutions, and advantages of this utility model clearer, several preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the embodiments described herein are merely for explaining this utility model and do not constitute any limitation on its scope of protection. Any modifications, equivalent substitutions, or improvements made based on the spirit and principles of this utility model should be included within the scope of protection of this utility model.

[0022] Example 1 Please see Figures 1 to 2 This embodiment discloses a complete structure of an adjustable pitch angle mounting base for an unmanned aerial vehicle (UAV) launcher.

[0023] The mounting base in this embodiment is based on a base 1, which serves as a rigid interface platform connecting the entire device to the drone fuselage. Structurally, the base 1 is a lightweight, irregularly shaped flat plate, its overall outline and dimensions precisely matched to the top platform dimensions of the drone to be mounted (e.g., an industrial-grade quadcopter drone). Its core design principle is to ensure maximum contact area and the most secure connection with the drone fuselage. To this end, multiple mounting through holes 13 are precisely formed on the base 1. The layout of these through holes perfectly matches the standard mounting points on the drone fuselage, allowing for multi-point fastening using standard-sized high-strength alloy steel bolts, thereby forming a rigid base without any wobbling or misalignment.

[0024] Above the base 1, there is a launcher bracket 2, whose direct function is to support and fix the launcher 7 as the mission payload. This launcher bracket 2 is a specially designed load-bearing component. Its overall structure has been optimized for maximum lightweighting while meeting extreme strength requirements, for example, by creating large-area hollowing in non-core load-bearing areas. Its core functional area is located on its upper surface, specifically designed for docking and fixing with the launcher 7.

[0025] To achieve pitch angle adjustment, a front hinge 5 rotatably connects the front end of the transmitter bracket 2 to the base 1. This front hinge 5 is the "center" or pivot of the entire motion mechanism, limiting the transmitter bracket 2 to a single degree of pitch rotation relative to the base 1. This precise motion constraint is the basis for achieving repeatable and accurate angle positioning.

[0026] Connecting the transmitter bracket 2 and the base 1 is an adjustable link 3, which serves as both a support rod and an adjustment rod. One end of the adjustable link 3 is connected to the lower middle rear part of the transmitter bracket 2 via a rotating joint, while the other end is detachably connected to the angle locking mechanism on the base 1. It functions like a variable-length support arm; by changing its connection point with the base 1, it can be used like a jack to "push" the transmitter bracket 2 to different pitch angles.

[0027] This angle locking mechanism achieves discrete adjustability and absolute locking of the angle in the purest mechanical way. The mechanism includes multiple adjustment holes 31 spaced along the length of the adjustable link 3, and positioning pin holes on the base 1. Locking is achieved through a positioning element 4, which can be a pin or bolt. Its working principle is as follows: When an angle needs to be set, the operator pulls out the positioning element 4, leaving the lower end of the adjustable link 3 in a free state. The operator manually lifts or presses down the transmitter bracket 2 to achieve the desired pitch angle. During this process, the adjustable link 3 swings, and its row of adjustment holes 31 sequentially sweeps across the positions of the fixed positioning pin holes on the base 1. When a certain adjustment hole 31 is perfectly aligned with the positioning pin hole in space, the operator re-inserts the positioning element 4 into these two aligned holes. Once the positioning element 4 is fully inserted, its rod is simultaneously radially constrained by both the adjustment hole 31 and the positioning pin hole, completely locking the relative position between the adjustable link 3 and the base 1, thus precisely fixing the pitch angle of the transmitter bracket 2. This method of positioning and locking, which relies solely on the shearing force of the pin hole, has a positioning accuracy that depends only on the machining accuracy of the hole and the pin. After locking, it has extremely high rigidity and can resist the huge impact force during launch to a considerable extent.

[0028] The upper surface of the launcher bracket 2 in this embodiment is provided with a V-shaped groove 21 for supporting the launcher, and the distance between the two sides of the V-shaped groove 21 gradually decreases along the recoil force direction opposite to the launch direction of the launcher. This is a core design feature of this solution, which can convert passive impact force into active locking force of the wedge-shaped self-locking structure. Geometrically, the V-shaped groove 21 forms a tapered shape that converges towards the rear of the launcher. A V-shaped locking block is installed at the bottom of the launcher body to cooperate with this. During initial installation, the launcher slides in from the wider front end until it reaches the predetermined position and is initially fixed using conventional methods (such as lateral screws). At this time, there may still be a gap between the groove and the locking block. However, at the moment the launcher is triggered, a high-peak instantaneous recoil force is generated along its axis. This force will cause the launcher to move slightly backward. It is this sudden movement that triggers the wedge-shaped self-locking effect: the V-shaped locking block is forced into the increasingly narrow V-shaped groove, much like driving a wedge into a V-shaped crack. According to the principles of physics, this process generates a huge positive pressure perpendicular to the contact surface, thus pressing the launcher firmly against the bracket with tremendous force. This self-locking process is completed in a very short time, and its core advantage lies in the fact that the greater the recoil, the stronger the wedge-shaped locking force. It cleverly transforms the impact force, which is considered a harmful factor, into a beneficial factor that enhances system stability. This design not only fundamentally eliminates any possibility of the launcher loosening, shifting, or even falling off due to severe impact, but also dynamically eliminates all potential assembly gaps at the moment of launch, ensuring that the launcher and the mounting base are truly tightly engaged and integrated at the most critical moment, providing the highest level of guarantee for launch stability and absolute system safety. Compared to methods relying solely on bolt friction or conventional clips for fixation, the connection reliability of this solution is greatly improved.

[0029] In a preferred embodiment of this invention, to further optimize its kinematic characteristics and structural layout, the adjustable link 3 is designed as an arc-shaped link, and the plurality of adjustment holes 31 are distributed along the arc path of the arc-shaped link. This arc design is based on precise kinematic calculations. The design reference is: using the axis of the positioning pin hole on the base 1 as the center and the effective length of the adjustable link 3 (i.e., the distance from its upper hinge point to its lower locking point) as the radius, the theoretical motion trajectory arc is drawn. Designing the physical form of the adjustable link 3 itself as an arc that closely matches this theoretical motion trajectory allows for more coordinated and smoother relative movement between the link and the positioning seat on the base throughout the entire angle adjustment range. This avoids the problem that when the linear link swings significantly, its endpoint may cause undesirable interference with the positioning seat or require a larger clearance space. Meanwhile, the adjustment holes 31 are evenly distributed or distributed according to a specific pattern (such as equal angle difference) along this optimized arc path, ensuring that the pitch angle of the transmitter bracket 2 can produce an expected and relatively uniform change every time a hole position is switched. This makes the angle adjustment have good linearity and predictability, which facilitates the user's quick operation and positioning.

[0030] To achieve ultimate structural stability and torsional stiffness, the mounting base described in this embodiment includes two symmetrically arranged adjustable connecting rods 3 and an angle locking mechanism, located on the left and right sides of the launcher bracket 2, respectively. This dual-sided symmetrical layout improves the reliability of the mechanical design. First, it upgrades single-point or single-line support to a stable dual-point planar support. When the recoil force of the launcher is not fully applied to the centerline due to manufacturing tolerances, uneven propellant loading, or airflow effects, a harmful torque will inevitably be generated, attempting to cause the launcher bracket 2 to twist horizontally. The connecting rods and locking points on both sides form a powerful closed structure with extremely high torsional stiffness, effectively decomposing this torsional torque into tensile or compressive forces on both sides of the connecting rods. This ensures that the launcher bracket 2 only produces a pure pitch tendency under impact, without any lateral sway or twisting that affects ballistic accuracy. Secondly, when subjected to pure pitch direction recoil, the impact load is evenly distributed to the left and right sets of linkages and locking mechanisms, which halves the stress on individual components. This greatly improves the fatigue life and ultimate load-bearing capacity of the entire device, enabling it to adapt to loads with higher launch energy or a longer service life.

[0031] This embodiment provides a specific and detailed description of the structure of the front hinge portion 5. The front hinge portion 5 includes a pair of first hinge seats 51 fixed on the base 1 and a second hinge seat 52 fixed on the front end of the transmitter bracket 2. The second hinge seat 52 is disposed between the pair of first hinge seats 51 and passes through the first hinge seat 51 and the second hinge seat 52 coaxially via a rotating shaft 53, forming a rotatable connection.

[0032] In practical use, the gap between the two ends of the second hinge seat and the first hinge seat should be small enough to ensure that the second hinge seat 52, as a moving part, is firmly clamped in the middle by the first hinge seats 51 fixed on both sides, effectively limiting any movement of it in the axial direction of the shaft 53 and greatly enhancing its ability to resist lateral bending moments. Alternatively, a second hinge seat can be provided for each of the two first hinge seats to mate with it. This avoids the problems of excessively long hinge seats, difficult manufacturing, and heavy weight caused by using only a single second hinge seat. The shaft 53 itself can be made of high-strength alloy steel material that has undergone surface quenching and precision grinding, with extremely high surface hardness and smoothness. Specifically, it can be a pin, dowel, or bolt. The reaming holes on the first and second hinge seats that mate with it can be machined by high-precision boring, and the hole walls can be embedded with self-lubricating bearing bushings or lubricating oil. The high-precision clearance fit between the shaft and the bushing ensures absolutely smooth rotation and low friction, while controlling the radial clearance to the micrometer level, eliminating any potential wobble or misalignment that could affect aiming accuracy. This precise hinge structure is the solid foundation for the entire mounting base to achieve accurate angle adjustment and maintain long-term stability.

[0033] To further improve the strength, durability, and maintainability of the locking mechanism, this embodiment optimizes the arrangement of the positioning pin hole. Instead of being directly formed on the thinner base 1 plate or bent from a portion of the base, the positioning pin hole is formed on an additional positioning seat 12 fixed to the upper surface of the base 1. This positioning seat 12 is a separate, solid metal block of considerable thickness, securely fixed to the upper surface of the base 1 from below using two or more high-strength countersunk screws. Placing the positioning pin hole on such a thick base offers at least two major advantages: First, it enhances shear resistance. The axial length of the pin hole (i.e., the engagement depth) increases from the thickness of the thinner base 1 to the entire thickness of the positioning seat 12. This means the effective contact area (i.e., shear bearing area) between the positioning element 4 and the hole wall is multiplied, allowing the locking point to withstand several times the shear force of a hole directly in the base plate, which is crucial for resisting powerful launch impacts. Second, it significantly improves maintainability. In long-term, high-frequency use, repeated insertion and removal of the pins inevitably causes wear on the hole walls. If holes are directly drilled on the base 1, once the holes are worn beyond tolerance, it will lead to inaccurate positioning or wobbling, and repairing or replacing the entire complex base 1 is extremely costly. With this solution, wear only occurs on the replaceable positioning seat 12. If a problem occurs, simply replace this simple and inexpensive positioning seat 12, restoring the entire device to its original condition and greatly reducing the maintenance cost throughout its entire lifecycle.

[0034] To construct a complete linkage mechanism with clearly defined kinematic relationships, this embodiment specifies the connection method of the upper end of the adjustable link 3. The end of the adjustable link 3 furthest from the angle locking mechanism (i.e., its upper end) is rotatably connected to the lower surface of the launcher bracket 2 via a third hinge seat 32. The structure of the third hinge seat 32 is similar to that of the front hinge part 5, also a stable and reliable rotating joint, consisting of a pin and a hinge hole. It ensures that the adjustable link 3 can swing freely with the pitch of the launcher bracket 2 while supporting it, thereby enabling the entire four-bar linkage (composed of the base 1 as the frame, the launcher bracket 2 and the adjustable link 3 as the movable rods, and the front hinge part 5 and the third hinge seat 32 as the rotating joint) to move smoothly without any motion interference or stress concentration.

[0035] To ensure the entire mounting base can be securely and reliably installed on the UAV platform, this embodiment specifically defines the mounting interface of the base 1. The base 1 is a flat plate structure with multiple mounting through holes 13 for fixing it to the UAV fuselage. The position, number, and diameter of these mounting through holes 13 can be designed according to the top standard interface of mainstream UAV platforms in the industry, providing good versatility and compatibility. The periphery of the holes is countersunk or chamfered so that the bolt heads can be flush with or below the base surface, avoiding interference with other components. Through these multiple fixing points distributed around the base, the recoil force generated during launch and various vibration loads during flight can be evenly distributed to the entire fuselage structure of the UAV, avoiding stress concentration and ensuring flight safety and long-term installation reliability. Embodiment 2 is as follows. Figures 3-4 As shown, this utility model also provides a drone, including a fuselage 6, a transmitter 7, and the aforementioned drone-borne transmitter pitch angle adjustable mounting base. The flight unit and the transmitter are connected through the drone-borne transmitter pitch angle adjustable mounting base. Through the adjustable mounting base, the drone can flexibly select the transmitter and the specific angle of the transmitter according to the mission situation, which enhances adaptability and flexibility, facilitates disassembly and replacement required for maintenance, and expands the applicable scenarios.

[0036] In summary, this utility model, through the ingenious combination of a base, a launcher bracket, a front hinge, an adjustable connecting rod, and an angle locking mechanism, and especially through the introduction of a series of optimized technical features such as a tapered V-shaped slot self-locking structure, a double-sided symmetrical arc connecting rod, and a thickened positioning seat, has successfully developed an adjustable pitch angle mounting base for UAV launchers that integrates high reliability, high safety, low cost, lightweight, and ease of operation. It perfectly solves many problems existing in the prior art and has extremely high practical value and broad market application prospects.

Therefore, the protection scope of the present utility model should be determined by the scope defined in the appended claims.
