[0031] See also Figure 1-2 , the present application proposes a drone with a load throwing device 2, comprising a drone body 1 and a throwing device 2;

[0032] The drone body 1 is equipped with a connecting rod 3, and the throwing device 2 includes an assembly platform 4 and a quick-release assembly. The quick-release assembly is arranged on the assembly platform 4 and is detachably connected to the connecting rod 3. The quick-release assembly includes a limit seat 5, a limit plate 6, and a fixing member 7. The limit seat 5 is installed on the assembly platform 4, the limit plate 6 is rotatably connected to the limit seat 5, and the fixing member 7 can pass through the limit plate 6 and be fixedly connected to the limit seat 5.

[0033] By rotating the limit plate 6, the present application can assemble the connecting rod 3 between the limit plate 6 and the limit seat 5, and then fix the limit seat 5 and the limit plate 6 together through the fixing part 7, thereby realizing the rapid disassembly and assembly of the throwing device 2. In addition, the quick-release assembly can be fixedly installed at different positions of the connecting rod 3, thereby realizing the position center of gravity adjustment of the throwing device 2, ensuring that the drone can maintain balance and stability when carrying a load.

[0034] A universal quick-release assembly is designed to facilitate rapid installation and use of different models of drone bodies 1. The fixing member 7 can be a thumb screw, etc., which is clamped to prevent it from falling off. Due to the different force directions, the bearing force is mainly borne by the limit seat 5 and the limit plate 6. The thumb screw only has a fixing function, so it is safe and stable.

[0035] By adjusting the position and angle of the servo, the center of gravity of the payload relative to the drone can be changed, thereby ensuring the stability of the drone during flight and casting.

[0036] like Figure 4 As shown, the throwing device 2 further includes two throwing assemblies 8 , and the two throwing assemblies 8 are symmetrically arranged at the bottom of the assembly platform 4 .

[0037] On the one hand, the two throwing components 8 are installed symmetrically to ensure the torque balance on the left and right sides, which can reduce the vibration and deviation of the drone during flight and throwing, and improve the overall stability and accuracy; on the other hand, the two-stage throwing design will make the drone have higher flexibility and accuracy in the throwing process. Whether it is simulating real scenes in drills and training, or accurately delivering rescue supplies in rescue missions, the thrower can play an important role.

[0038] Before the drone is officially put into use, the throwing device 2 is fully tested and verified. The performance and reliability of the throwing device 2 are evaluated by simulating different flight conditions and load conditions. At the same time, the design solution is optimized and improved based on the test results to improve the overall performance of the throwing device.

[0039] like Figure 3 As shown, in some embodiments, the throwing assembly 8 includes a servo motor 801, a linkage arm 802, a mounting load-bearing frame 803 and a mounting slide 804; the mounting load-bearing frame 803 includes a front section 8031 and a rear section 8032, and there is a hollow structure between the front section 8031 and the rear section 8032, and the front section 8031 and the rear section 8032 are both provided with through holes, and the mounting slide 804 is slidably connected to the through holes; the output end of the servo motor 801 is connected to one end of the linkage arm 802, and the other end of the linkage arm 802 is connected to the mounting slide 804.

[0040] Through the precise control of the servo motor 801, the throwing action can be accurately executed to ensure that the load can be accurately dropped to the specified position; the high-precision control characteristics of the servo motor 801 make the throwing process more stable and reliable.

[0041] The mounting load-bearing frame 803 adopts a hollow structure design of the front section 8031 and the rear section 8032, so that the hollow structure serves as the mounting load-bearing hook position, and the mounting slide column 804 is slidably connected in the through hole, so that the casting assembly 8 can withstand a large load without causing structural deformation or damage, ensuring that the machine does not get stuck or stalled during the casting process, and achieving accurate and stable casting effects.

[0042] The servo motor 801 is used to link the sliding column through the load-bearing holes at both ends, and the middle is the load-bearing hook to ensure the load-bearing strength and that the drone will not be thrown off during flight until it receives the throwing command.

[0043] Preferably, a stable and reliable heavy-load circuit system is designed to ensure that the servo motor 801 can still operate normally under heavy load conditions. A precise servo motor 801 control system is used to ensure that the servo motor 801 can quickly and accurately execute actions after receiving instructions. At the same time, by introducing sensor monitoring technology, the state parameters of the servo motor 801 are monitored in real time, so that the control strategy can be adjusted in a timely manner.

[0044] Further preferably, the mounting load-bearing frame 803 and the mounting slide column 804 are both made of high-strength, lightweight materials, such as carbon fiber composite materials or high-strength engineering plastics, to ensure that they can still maintain sufficient strength and toughness when bearing large loads.

[0045] In some embodiments, a self-lubricating bearing (not shown) is provided in the through hole, and the through hole is slidably connected to the mounting slide 804 via the self-lubricating bearing.

[0046] There is a self-lubricating bearing between the mounting slide 804 and the mounting load-bearing frame 803. The mounting slide 804 is high in strength. Generally, when the load increases, the mounting slide 804 bends due to excessive bearing capacity, causing it to deviate from the axis of the load-bearing slide hole and get stuck, resulting in casting failure. The high-strength mounting slide 804 and self-lubricating bearing can effectively solve this problem, thereby increasing the load capacity.

[0047] The introduction of self-lubricating bearings significantly reduces frictional resistance when mounting slide 804 slides within the through-hole. This not only reduces heat and energy loss due to friction, but also extends the service life of mounting slide 804 and the through-hole, reducing wear and tear that can occur due to long-term friction.

[0048] The high-strength mounting post 804, combined with the self-lubricating bearing, can more effectively withstand large loads. Even under increased load, the mounting post 804 is less likely to bend due to excessive load-bearing capacity, thus avoiding the problem of deviation from the axis of the load-bearing slide hole, ensuring the stability and reliability of the casting device 2 and improving the load capacity of the drone.

[0049] In such Figure 3 As shown, in some embodiments, the throwing assembly 8 further includes a mounting plate 805 , which is fixedly connected to the bottom of the assembly platform 4 . The mounting plate 805 is connected to a mounting bracket 806 , and the servo motor 801 is fixed in the mounting bracket 806 .

[0050] Mounting plate 805 is a crucial component connecting assembly platform 4 and casting assembly 8. Its secure connection ensures the stability of casting assembly 8 during drone flight. The tight connection between mounting plate 805 and the bottom of assembly platform 4, along with its support for mounting bracket 806, creates a robust mechanical structure, effectively preventing casting assembly 8 from shaking or falling during flight, thereby enhancing the stability of the entire drone system.

[0051] Servo motor 801 is secured within mounting bracket 806, effectively protecting it and enhancing the stability of the sliding drive slide 804. Mounting bracket 806 not only provides sturdy support for servo motor 801 but also isolates it from external vibration and shock, minimizing their impact on the motor's operating accuracy and lifespan. Furthermore, the design of mounting bracket 806 facilitates maintenance and overhaul of servo motor 801, improving overall maintainability.

[0052] like Figure 3 As shown, in some embodiments, the mounting load-bearing frame 803 is fixedly connected to the mounting plate 805 via a fixing frame 807 .

[0053] By firmly connecting the mounting load-bearing frame 803 to the mounting plate 805 via the fixing frame 807, the structural rigidity of the entire casting assembly 8 can be significantly improved. The connection reduces structural deformation caused by vibration or load changes, and ensures stability and accuracy during the casting process.

[0054] like Figure 2 As shown, in some embodiments, the limiting plate 6 is an arc-shaped structure.

[0055] The contact surface between the arc-shaped limit plate 6 and the connecting rod 3 is larger and more evenly distributed, which helps to disperse stress, reduce local wear, and extend the service life of the limit plate 6. The arc-shaped limit plate 6 can better adapt to connecting rods 3 of different shapes and sizes, improving the versatility and adaptability of the quick-release assembly.

[0056] In some embodiments, the assembly platform 4 is a carbon fiber assembly platform 4 .

[0057] Carbon fiber materials have extremely high specific strength and specific stiffness. Using the carbon fiber assembly platform 4 can significantly reduce the overall weight of the UAV and improve flight efficiency and endurance.

[0058] like Figure 4 As shown, in some embodiments, a power supply device 9 is provided on the assembly platform 4 , and the power supply device 9 is used to supply power to the throwing device 2 .

[0059] Power supply 9, installed on assembly platform 4, is specifically designed for casting device 2 and provides stable and continuous power output, ensuring the proper operation of servo motor 801 and other electronic equipment even under extended operating conditions or high loads, without compromising casting accuracy and stability due to power fluctuations. Optionally, power supply 9 incorporates safety measures such as overload and overheat protection to ensure safe and stable operation of the entire system, effectively preventing equipment damage and safety incidents, and safeguarding the safety of the drone and its operator.

[0060] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention, and should all be included in the scope of protection of the present invention.
