Description

Technical Field

[0001] This utility model is a mounting device for unmanned aerial vehicles (UAVs), belonging to the field of UAV technology. Background Technology

[0002] The drone mounting system is a core component that uses a dedicated connection structure to stably assemble various mission equipment onto the drone fuselage. Its core value lies in breaking the drone's "single-purpose flight tool" positioning, allowing it to adapt to multiple scenarios such as aerial photography, inspection, and operations by carrying different functional mission equipment, thus becoming a comprehensive platform with specific operational capabilities. In actual mounting operations, a common basic solution is to fix a mounting plate to the middle of the bottom of the drone fuselage. The mounting plate is tightly connected to the fuselage structure through pre-set mounting holes, forming a stable load-bearing foundation. The mission equipment is rigidly fixed to the mounting plate with bolts. The tightening force of the bolts ensures that the relative position of the equipment with the mounting plate and fuselage remains stable during flight, preventing displacement due to vibration or airflow impact, thus achieving reliable mounting of the mission equipment.

[0003] For long-length mission equipment (such as elongated detectors and multi-lens mapping components), to reduce the equipment's lateral space occupation on the UAV and lower air resistance during flight, it is typically arranged along the length of the UAV's fuselage. However, this arrangement can easily lead to new problems when dealing with elongated equipment whose center of gravity is not at its own center: once the equipment's center of gravity deviates from the fuselage's central axis, it disrupts the UAV's original balance, causing the fuselage to tilt. During flight, the UAV needs to continuously adjust its motor speed or attitude to maintain balance, which not only increases the burden on the flight control system but may also cause attitude response delays, hovering instability, and in severe cases, even affect flight path accuracy, reduce operational reliability, and pose a potential risk to flight safety. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mounting device for a drone to solve the problems mentioned in the background technology. This utility model realizes the adjustment of the overall center of gravity according to the center of gravity of the mission equipment, so that the fuselage is in a state of center of gravity balance during flight.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mounting device for a drone, comprising:

[0006] body;

[0007] Two horizontal tubes are provided, which are symmetrically arranged on the lower side of the machine body. Two symmetrically arranged hanging seats are installed on the lower surface of the machine body. The horizontal tubes pass through the two hanging seats and maintain a fixed relative position with the hanging seats. The horizontal tubes are arranged along the length of the machine body.

[0008] The mounting plate has two symmetrically arranged retaining rings installed on its upper surface. The two retaining rings are respectively engaged with two horizontal tubes and maintain a fixed relative position with the horizontal tubes.

[0009] The counterweight has two symmetrically arranged sliding sleeves installed on its upper surface. The two sliding sleeves on one counterweight are respectively fitted onto two horizontal tubes.

[0010] The limiting component is installed between the machine body and the counterweight.

[0011] Furthermore, the limiting member includes:

[0012] A screw is disposed between two horizontal tubes, the screw is arranged parallel to the horizontal tubes, and the screw maintains a constant relative position with the machine body;

[0013] The support lugs are provided in two ways, and the two support lugs are respectively connected and fixed to two counterweights. A first horizontal hole is opened on one side of each support lug, and the screw passes through the first horizontal hole.

[0014] The first nut is provided on both sides of the two supporting lugs, and the first nut is threadedly connected to the screw.

[0015] Furthermore, a positioning ear is installed at the middle position of the bottom of the machine body. A second horizontal hole is opened on one side of the positioning ear. The screw passes through the second horizontal hole. A second nut is provided on both sides of the positioning ear. The second nut is threadedly connected to the screw.

[0016] Furthermore, the suspension base has a "U" shaped structure, and shaft holes are provided at both ends of the suspension base away from the machine body, through which the horizontal tube passes.

[0017] Furthermore, the counterweight is a hollow structure, and a feeding port is installed on the upper surface of the counterweight. A threaded cap is threadedly connected to the upper end of the feeding port.

[0018] Furthermore, the fuselage includes two parallel plates that are connected and fixed to each other. Four evenly arranged wing arms are installed in the space formed by the two plates, and a mount for mounting a motor is installed at the end of each wing arm away from the plate.

[0019] Furthermore, a rectangular frame is installed at the middle of the bottom of the fuselage, and two connecting lugs for connecting the landing gear are symmetrically installed on the side of the rectangular frame facing away from the fuselage.

[0020] Furthermore, the inner diameter of the sliding sleeve is the same as the outer diameter of the horizontal tube, and a connecting plate is fixedly connected to the outer surface of the sliding sleeve. The end of the connecting plate away from the sliding sleeve is fixedly connected to the counterweight.

[0021] The beneficial effects of this utility model are:

[0022] The counterweight is mounted on the horizontal tube via a sliding sleeve and can slide along the tube to either side of the fuselage. If the mission equipment still experiences a slight center of gravity shift, the counterweight can be slid to the opposite side of the shift direction. The weight of the counterweight counteracts the shifting force, ensuring the fuselage remains in a balanced state and avoiding problems such as flight instability and attitude response delay caused by imbalance. Through center of gravity balance control, the UAV does not need to continuously adjust motor speeds or attitude to maintain balance, reducing the burden on the flight control system, lowering the probability of attitude response delay and hovering instability, ensuring the UAV can fly stably along the preset route, and improving route accuracy. At the same time, in a balanced state, the UAV's power consumption is more even, reducing unnecessary energy waste and indirectly extending the single flight time. Attached Figure Description

[0034] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0035] Please see Figures 1-3 This utility model provides a technical solution: a mounting device for a drone, including a fuselage 1, a rectangular frame 13 installed at the middle of the bottom of the fuselage 1, two connecting ears 14 for connecting the landing gear symmetrically installed on the side of the rectangular frame 13 away from the fuselage 1, the fuselage 1 includes two parallel plates, the two plates are connected and fixed to each other, four evenly arranged wing arms 11 are installed in the space formed by the two plates, and a carrier 12 for mounting a motor is installed at the end of the wing arm 11 away from the plate.

[0036] See Figures 1-3 There are two horizontal tubes 4, which are symmetrically arranged on the lower side of the body 1. Two symmetrically arranged hangers 41 are installed on the lower surface of the body 1. The horizontal tubes 4 pass through the two hangers 41 and maintain a constant relative position with the hangers 41. The hangers 41 have a "U" shape structure. The two ends of the hangers 41 away from the body 1 are provided with shaft holes. The horizontal tubes 4 arranged along the length of the body 1 pass through the shaft holes. The "U" shaped hangers 41 do not affect the arrangement of the screw 3.

[0037] See Figures 1-4 Two symmetrically arranged retaining rings are installed on the upper surface of the mounting plate 5. The two retaining rings are respectively engaged with the two horizontal tubes 4 and remain in a fixed relative position with the horizontal tubes 4. Two symmetrically arranged sliding sleeves 21 are installed on the upper surface of the counterweight part 2. The inner diameter of the sliding sleeve 21 is the same as the outer diameter of the horizontal tube 4. A connecting plate is fixed to the outer surface of the sliding sleeve 21. The end of the connecting plate away from the sliding sleeve 21 is fixed to the counterweight part 2. The connecting plate serves to connect the sliding sleeve 21 and the counterweight part 2. The two sliding sleeves 21 on one counterweight part 2 are respectively fitted onto the two horizontal tubes 4. The two sliding sleeves 21 fixed to the upper surface of the counterweight part 2 by the connecting plate can slide smoothly along the length of the horizontal tube 4 to one side of the machine body 1. During the sliding process, they always maintain a stable fit with the horizontal tube 4 to avoid shaking due to excessive gap. When mounting long, non-centered mission equipment, the operator can directly push the counterweight 2 to slide it to the opposite side of the offset direction. For example, if the equipment's center of gravity is biased towards the front of the fuselage 1, the counterweight 2 can be slid to the rear of the fuselage 1. The counterweight 2's own weight creates a counterbalancing torque, counteracting the imbalance caused by the equipment's offset. This dynamic adjustment method can quickly correct the fuselage 1's center of gravity without disassembling or modifying the mission equipment, ensuring that the UAV remains in a balanced state when carrying equipment with different degrees of eccentricity. This fundamentally avoids problems such as flight instability, fuselage 1 tilting during hovering, and attitude response delay caused by center of gravity imbalance.

[0038] If the center of gravity of the fuselage 1 is offset, the UAV flight control system needs to continuously adjust the motor speed (e.g., increase the speed of the motor on the heavier side to counteract the tilt force) or change the flight attitude. This prolonged high-load operation can easily lead to attitude adjustment lag, hovering position drift, and in severe cases, affect flight path accuracy, causing deviations in operational data (such as aerial images and detection data). After achieving center of gravity balance through the counterweight 2, the UAV fuselage 1 experiences uniform force. The flight control system does not need to consume additional computing power to adjust attitude or motor parameters, significantly reducing its burden. This avoids attitude response delays caused by high-load operation and ensures the UAV maintains the preset flight path, reducing positional deviations during flight. It is particularly suitable for scenarios with high flight path accuracy requirements, ensuring the accuracy of operational results. When the UAV is in a balanced state, the motors of each wing arm 11 do not need to increase their speed to maintain balance, resulting in more uniform power output and more rational energy consumption. This avoids energy waste caused by some motors operating under overload in traditional eccentric load configurations.

[0039] See Figures 1-4 The screw 3 is positioned between two horizontal tubes 4, and the screw 3 is arranged parallel to the horizontal tubes 4. A positioning ear 34 is installed at the middle position of the bottom of the machine body 1. A second horizontal hole is opened on one side of the positioning ear 34, and the screw 3 passes through the second horizontal hole. A second nut 33 is provided on both sides of the positioning ear 34. The second nut 33 is threadedly connected to the screw 3. Under the action of the two second nuts 33 and the positioning ear 34, the screw 3 and the machine body 1 maintain a constant relative position. Two support ears 32 are provided. The two support ears 32 are respectively connected and fixed to two counterweights 2. A first horizontal hole is opened on one side of the support ear 32, and the screw 3 passes through the first horizontal hole. A first nut 31 is provided on both sides of the two support ears 32, and the first nut 31 is threadedly connected to the screw 3. The screw 3 passes through the positioning ear 34 and the two second nuts 33 restrict the relative position of the screw 3 and the positioning ear 34, which facilitates the disassembly and assembly of the screw 3 and the machine body 1. When the position of the counterweight 2 is adjusted, the relative position of the support ear 32 and the screw 3 changes. When the position of the counterweight 2 is adjusted to the required position, the first nut 31 is used to restrict the relative position of the support ear 32 and the screw 3, so as to realize the stepless adjustment of the position of the counterweight 2.

[0040] The counterweight 2 is a hollow structure. A feeding port 23 is installed on the upper surface of the counterweight 2, and a threaded cap 22 is threadedly connected to the upper end of the feeding port 23. The counterweight 2 is a hollow structure, and the internal counterweight material (such as sand, gravel, or metal blocks) can be added or removed through the feeding port 23 to flexibly adjust the counterweight weight and adapt to task equipment with different weights and different degrees of eccentricity.

The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
