Description

Technical Field

[0001] This utility model belongs to the field of unmanned transport aircraft technology, and in particular relates to an anti-rollover structure for unmanned transport aircraft. Background Technology

[0002] When performing transport missions, unmanned transport aircraft are prone to tilting or even overturning in harsh environments due to cargo center of gravity shift, airflow disturbances, or landing impacts, threatening equipment safety and transport stability.

[0003] Existing anti-tipping structures mostly rely on active control systems. For example, according to publication number CN212530080U, titled "Anti-tipping bracket for a delivery drone," it solves the problem that existing delivery drones are small in size, making it inconvenient to transport large items. Their unstable center of gravity may cause them to tip over, damaging the packages and causing economic losses. The delivery drones may also be damaged, making repairs troublesome and increasing costs.

[0004] However, during use, it requires additional energy and has a delayed response, making it difficult to respond to sudden imbalances in real time. It also suffers from high energy consumption and high maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-rollover structure for unmanned transport aircraft to solve the technical problem mentioned in the background art that the fuselage tilts or even rolls over due to cargo center of gravity shift, airflow disturbance or landing impact in harsh environments. By setting up a frame filled with a floating solution and a buoyancy ball to form a passive balance system, and combining it with the active adjustment function of tilt sensor and linear motor driven counterweight plate, the risk of rollover caused by instantaneous imbalance during the operation and landing of unmanned transport aircraft can be effectively prevented.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: An anti-tipping structure for an unmanned transport aircraft includes a frame, the inner surface of which is hollow. Floating balls are symmetrically arranged along the central axis of the frame's inner cavity, and a guide assembly is connected to the bottom inner side of the frame. The guide assembly communicates with the inner cavity of the frame. Simultaneously, both the inner cavities of the frame and the guide assembly are filled with a buoyancy solution. The frame and the floating balls cooperate to adjust the frame to a horizontal state.

[0007] Preferably, the density of the floating solution is greater than the density of the buoyancy ball, the floating solution is mercury, and the buoyancy ball is a solid iron ball.

[0008] Preferably, the guide assembly includes two guide frames arranged symmetrically, and a center-of-gravity ball cylinder disposed at one end opposite to the two guide frames, wherein the opposite side of the two guide frames and the side connected to the center-of-gravity ball cylinder are interconnected.

[0009] Preferably, the end of the buoyancy ball is connected to a ball rope, and two fixed seats are symmetrically arranged at the end of the inner cavity of the frame. At the same time, the end of the ball rope is connected to the bottom of the fixed seat.

[0010] Preferably, a linear motor is installed at the inner end of the frame, and a counterweight plate is connected to the output end of the linear motor. At the same time, a tilt sensor is installed above the frame.

[0011] Preferably, the bottom of the frame is connected to a connecting cylinder, and a support rod is provided through the bottom of the inner cavity of the connecting cylinder. At the same time, the bottom of the connecting cylinder is connected to a support foot.

[0012] Preferably, an elastic element is connected to the top of the inner cavity of the connecting cylinder, and the other end of the elastic element is connected to the end of the adjacent support rod.

[0013] A plug rod is installed at the top of the inner cavity of the connecting cylinder and on the inner surface of the elastic element;

[0014] The end of the support rod surface has a through slot, and the bottom of the insertion rod extends into the inner cavity of the slot.

[0015] Preferably, the support foot is T-shaped, with its end sleeved to the bottom of the support rod, and both ends of the bottom of the support foot are fitted with rubber sleeves.

[0016] Preferably, multiple spheres are movably embedded at both ends of the bottom of the support foot, and the ends of the spheres are provided with grooves.

[0017] Preferably, a ball is slidably disposed in the groove, and a cap is movably mounted on the end of the ball, wherein a connecting rod is connected to the end of the cap.

[0018] The anti-tipping structure for unmanned transport aircraft of this utility model has the following advantages:

[0019] This unmanned transport aircraft anti-tipping structure features a frame cavity filled with mercury. Symmetrically arranged solid iron balls, treated for rust prevention, float in the mercury and are connected to a fixed base via ball ropes. When the frame tilts, the mercury accumulates on the lower side, causing the higher-side ball to sink due to insufficient buoyancy caused by reduced submerged volume. The taut ball ropes generate a downward pull, creating a restoring torque. Simultaneously, the increased mass of the mercury on the lower side further provides the restoring torque, automatically leveling the frame. A tilt sensor monitors the tilt signal in real time and triggers a central processing unit to control a linear motor to drive a counterweight plate to move in the opposite direction of the tilt, dynamically adjusting the center of gravity. During landing, the T-shaped structure and rubber sleeves of the support legs buffer the impact, while the support rods absorb vibration through compressed elastic elements within the connecting cylinders. The insertion rods and slotted limiters enhance stability. The spherical bodies and ball bearings at the bottom of the support legs allow for slight slippage through grooves, eliminating braking recoil. Combined with limiting grooves, this prevents the ball bearings from falling off, ensuring a smooth landing for the transport aircraft. Attached Figure Description

[0038] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an anti-tipping structure for an unmanned transport aircraft.

[0039] like Figures 1-10 As shown, the present invention discloses an anti-tipping structure for an unmanned transport vehicle, comprising a frame 200, wherein the inner surface of the frame 200 is hollow, wherein, as Figure 6 As shown, buoyancy balls 240 are symmetrically arranged along the central axis inside the frame 200, and a guide assembly is connected to the bottom inner side of the frame 200. The guide assembly communicates with the inner cavity of the frame 200. Meanwhile, as... Figure 6 The frame 200 and the inner cavity of the guide assembly are both filled with a floating solution. The frame 200 and the buoyancy ball 240 cooperate to adjust the frame 200 to a horizontal state. When the frame 200 is in a horizontal state, the floating solution at both ends of the inner cavity of the frame 200 is level, and the two buoyancy balls 240 are in the same horizontal position, so that the frame 200 remains in a horizontal state.

[0040] The density of the floating solution is greater than the density of the buoyancy ball 240, which enables the buoyancy ball 240 to have a certain weight and float in the floating solution;

[0041] The floating solution is mercury, while the buoyancy ball 240 is a solid iron ball. Because the density of mercury is greater than that of a solid iron ball, when the bottom of the inner cavity of the frame 200 is filled with mercury, the buoyancy ball 240 can float in the mercury inside the frame 200.

[0042] Specifically, the bottom of the inner cavity of the rack 200 is filled with mercury, with a mercury density of 13.6 g / cm³. 3 The frame 200 has a solid iron ball at each end of its inner cavity, with a density of 7.87 g / cm³. 3 The density of the iron ball is less than that of mercury, so the iron ball will be partially submerged in the mercury water and float.

[0043] Specifically, the iron ball is treated to prevent rust, such as by coating the surface with stainless steel, while the inner cavity of the frame 200, guide frame 220 and center of gravity ball cylinder 230 is sealed.

[0044] As a further optimization of this scheme, a high-density fluorinated solution can also be used as the floating solution.

[0045] The guide assembly includes two guide frames 220 arranged symmetrically, and a center of gravity ball cylinder 230 disposed at one end opposite to the two guide frames 220. The opposite side of the two guide frames 220 and the side of the center of gravity ball cylinder 230 connected to each other are interconnected, so that the inner cavities of the frame 200, the guide frames 220 and the center of gravity ball cylinder 230 are all in a state of interconnection, and the floating solution is located at the bottom of the inner cavity of the frame 200 and the inner cavities of the guide frames 220 and the center of gravity ball cylinder 230.

[0046] As a further optimization of this solution, a counterweight ball can be provided inside the center of gravity ball cylinder 230 to increase the stability of the frame 200;

[0047] When the frame 200 tilts, the floating solution inside the frame 200 will gather towards the tilted end. The buoyancy ball 240 on the side with less floating solution will fall, while the ball rope 241 will taut, generating a downward pull and applying a restoring torque to the higher side, helping the frame 200 to return to level. This allows the frame 200 to provide passive balance without external power, as the buoyancy ball 240 and mercury will move immediately when tilted.

[0048] As a further optimization of this solution, in actual use, a floating plate is provided above the buoy 240. The surface of the floating plate slides in contact with the inner wall of the frame 200 to prevent the floating solution inside the frame 200 from shaking randomly during use.

[0049] The end of the buoyancy ball 240 is connected to a ball rope 241, and two fixed seats 242 are symmetrically arranged at the end of the inner cavity of the frame 200. At the same time, the end of the ball rope 241 is connected to the bottom of the fixed seat 242.

[0050] Specifically, the inner cavity of the rack 200 is a smooth U-shaped cavity, and its inner cavity material can be glass or stainless steel.

[0051] Specifically, the buoyancy ball 240 is suspended from the upper end of the inner cavity of the frame 200 by the ball rope 241. Since the buoyancy ball 240 floats, the rope is in a slack state and no tension is applied. At this time, the surface of the floating solution inside the frame 200 is horizontal, and the overall center of gravity of the device is stable.

[0052] When the frame 200 becomes unbalanced, if it tilts to one side (e.g., to the left), the floating solution accumulates to the left due to gravity, causing the level of the floating solution on the left to rise. The left-side buoyancy ball 240 remains submerged in the floating solution, and its buoyancy remains essentially unchanged, thus maintaining its floating state. The ball rope 241 may be slightly taut but not taut. Conversely, the level of the floating solution on the right side drops, reducing the submerged portion of the buoyancy ball 240. The buoyancy is insufficient to support its weight, and the buoyancy ball 240 falls under gravity until the ball rope 241 tauts. Once the ball rope 241 tauts, the right-side buoyancy ball 240 exerts a downward pulling force on the suspension point through the ball rope 241. The magnitude of this force is the weight of the buoyancy ball 240 minus the remaining buoyancy. However, due to the reduced floating solution, the buoyancy is very small, so the pulling force is close to the weight of the buoyancy ball 240 itself.

[0053] When tilted, the right-side buoy 240 drops and pulls the suspension point downward, generating a torque that lowers the higher side. Simultaneously, the floating solution accumulates on the lower side, i.e., the left side, increasing its mass and further generating a torque that causes the frame 200 to rotate clockwise.

[0054] The tension of the buoyancy ball 240 acts directly on the suspension point on the higher side, applying a downward force. The accumulation of the floating solution increases the weight on the lower side, indirectly generating a restoring torque. Ultimately, the frame 200 experiences a net restoring torque, pushing it back to a horizontal position. Once horizontal, the floating solution redistributes, the buoyancy ball 240 resumes buoyancy, the ball rope 241 slackens, and the system returns to its initial state.

[0055] To help increase the balance of the frame 200, prevent it from tipping over, and thus enhance its stability, a linear motor 700 is installed at the inner end of the frame 200. The output end of the linear motor 700 is connected to a counterweight plate 710. At the same time, a tilt sensor 300 is installed above the frame 200. The tilt sensor 300, the linear motor 700, and the counterweight plate 710 work together. When the tilt sensor 300 detects that the transport body 100 is tilted, it can transmit the information to the central processing unit on the transport body 100. The central processing unit controls the linear motor 700 to drive the counterweight plate 710 to move to the opposite side of the tilt of the frame 200, so that the frame 200 remains in a balanced state.

[0056] Specifically, the tilt sensor 300 is bidirectionally electrically connected to the central processing unit on the transport body 100, and the input terminal of the linear motor 700 is electrically connected to the output terminal of the central processing unit on the transport body 100. The central processing unit on the transport body 100 can control the operation of the linear motor 700. The specific connection between the central processing unit, the tilt sensor 300, and the linear motor 700 is existing technology and will not be described in detail in this solution.

[0057] Specifically, a transport body 100 is installed above the frame 200, and a transport compartment 110 is installed at the bottom center of the transport body 100. The transport compartment 110 can store goods, and the transport body 100 and the transport compartment 110 work together to transport goods.

[0058] The transport body 100 and the transport compartment 110 can be existing publicly disclosed technologies, such as CN221954568U, a cargo transport drone, or CN214930635U, a drone that facilitates cargo delivery. The transport body 100 and the transport compartment 110 are existing technologies, and this solution will not describe them in detail.

[0059] When the transport body 100 is placed on the ground, the frame 200, connecting cylinder 400, support rod 500 and support foot 600 work together to support the transport body 100.

[0060] Furthermore, connecting seats 210 are symmetrically arranged at the left and right ends of the surface of the frame 200, and the connecting seats 210 are fastened to the bottom of the transport body 100 by bolts; and by bolting the connecting seats 210 and the transport body 100, the frame 200 can be easily removed from the transport body 100.

[0061] The bottom of the frame 200 is connected to a connecting cylinder 400, and a support rod 500 is installed through the bottom of the inner cavity of the connecting cylinder 400. The end of the support rod 500 extends into the inner cavity of the connecting cylinder 400 and is sealed at the connection point. At the same time, the bottom of the connecting cylinder 400 is connected to a support foot 600. When the transport body 100 lands, the support foot 600 contacts the ground, and the frame 200, connecting cylinder 400, support rod 500 and support foot 600 work together to assist in supporting the frame 200.

[0062] An elastic element 410 is connected to the top of the inner cavity of the connecting cylinder 400, and the other end of the elastic element 410 is connected to the end of the adjacent support rod 500.

[0063] The connecting cylinder 400 has a plug rod 420 installed at the top of its inner cavity and on the inner surface of the elastic member 410, and the bottom of the plug rod 420 extends through to the inner surface of the support rod 500.

[0064] At the same time, such as Figure 7 As shown, a slot 501 is provided through the end of the support rod 500, and the bottom of the insert rod 420 extends into the inner cavity of the slot 501. When the transport body 100 lands, the support foot 600 first contacts the ground, and brings a certain impact force to cause the support foot 600 to vibrate. The vibration of the support foot 600 is transmitted to the support rod 500, and the support rod 500 is affected and moves within the connecting cylinder 400. Under the cooperation of the elastic element 410 and the insert rod 420, the force is eliminated, increasing the stability of the transport body 100 when it lands.

[0065] The support leg 600 is T-shaped, and its end is sleeved with the bottom of the support rod 500. Both ends of the bottom of the support leg 600 are fitted with rubber sleeves to reduce the vibration force transmitted by the support leg 600 when it contacts the ground.

[0066] Multiple spheres 610 are movably embedded at both ends of the bottom of the support foot 600, and the ends of the spheres 610 are provided with grooves 611.

[0067] A ball bearing 620 is slidably disposed within the groove 611, and a cap 621 is movably mounted on the end of the ball bearing 620. A connecting rod 622 is connected to the end of the cap 621, and the end of the connecting rod 622 is connected to the bottom surface of the support foot 600. When the support foot 600 contacts the ground, the sphere 610 first contacts the ground. Under the action of the groove 611, the sphere 610 can slide a short distance on the ground, and the distance the sphere 610 slides is limited by the length of the groove 611.

[0068] To prevent the ball 620 from detaching from the sphere 610, a limiting groove is provided on the surface of the sphere 610 and in the middle of the inner cavity of the groove 611. A limiting slide is fitted on the outer surface of the ball 620 and is slidably disposed in the inner cavity of the limiting groove. Therefore, the ball 620 cannot easily detach from the groove 611.

[0069] When the transport aircraft 100 lands, a direct stop would generate a certain amount of reverse force. The spherical object 610 can assist the support leg 600 in moving slightly horizontally when it contacts the ground, thereby eliminating the reverse force caused by the direct stop of the transport aircraft 100. This allows the transport aircraft 100 to land more smoothly on the ground and prevents it from tipping over.

[0070] The working principle of an anti-tipping structure for an unmanned transport aircraft: The inner cavity of the frame 200 is filled with mercury. Symmetrically arranged buoyancy balls 240 are solid iron balls with anti-rust treatment, floating in the mercury and connected to the fixed base 242 by ball ropes 241. When the frame 200 tilts, the mercury gathers to the lower side. The buoyancy balls 240 on the higher side, due to the reduced submerged volume, become insufficient and fall. The taut ball ropes 241 generate a downward pulling force, forming a restoring torque. At the same time, the increased mass of the mercury on the lower side further provides a restoring torque, causing the frame 200 to automatically return to horizontal. In addition, the tilt sensor 300 monitors the tilt signal in real time and triggers the central processing unit to control the linear motor 700 to drive the counterweight plate 710 to move in the opposite direction of the tilt, dynamically adjusting the center of gravity. Upon landing, the T-shaped structure and rubber sleeve of the support foot 600 buffer the impact, the support rod 500 compresses the elastic element 410 within the connecting cylinder 400 to absorb vibration, and the insertion rod 420 and the slot 501 limit the engagement to enhance stability; the sphere 610 and ball bearing 620 at the bottom of the support foot 600 are allowed to slide slightly through the rolling groove 611 to eliminate braking recoil force, and the limiting groove prevents the ball bearing from falling off, ensuring a smooth landing of the transport body 100.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
