Description

Technical Field

[0001] This utility model relates to the field of drone accessories technology, and in particular to drone landing gear with an anti-tipping buffer structure. Background Technology

[0002] Existing drone landing gear mostly uses a single support structure, which has limited cushioning performance and insufficient resistance to tipping over;

[0003] During takeoff and landing, drones are prone to tipping over due to uneven ground, excessive impact, or external interference, which can damage the fuselage or onboard equipment.

[0004] Meanwhile, traditional buffer structures are mostly single-layer springs or rubber pads, which are difficult to effectively absorb longitudinal and lateral impact forces during takeoff and landing. Long-term use can easily lead to fatigue failure and affect the service life of the drone.

[0005] Therefore, this utility model proposes a drone landing gear with an anti-rollover buffer structure. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drone landing gear with an anti-tipping buffer structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a drone landing gear with an anti-tipping buffer structure, including a take-off and landing platform, and further comprising;

[0008] The adapter component consists of a landing gear platform located below the landing platform and an inner sleeve. The inner sleeve is located at the center of the landing gear platform, and a connecting plate is located at the center of the landing gear platform. Elastic ropes are arranged between the connecting plate and the inner sleeve. There are a total of eight elastic ropes, which are arranged in a ring and the included angle between two adjacent elastic ropes is equal.

[0009] Furthermore, a buffer assembly is provided between the landing gear platform and the take-off and landing platform. The buffer assembly is composed of a buffer plate, the bottom of which is connected to a connecting support plate, and the top of which is connected to the take-off and landing platform.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: The buffer assembly connects the landing gear platform and the takeoff and landing platform through the buffer plate to form a stable force transmission path. During takeoff and landing, the fuselage load is transmitted to the buffer plate through the takeoff and landing platform, and then to the connecting plate. With the elastic structure of the matching components working together to unload the force, the impact energy is effectively absorbed, the fuselage vibration is reduced, and the load is evenly distributed to avoid uneven local stress. This not only improves the stability of takeoff and landing, but also reduces the damage to the fuselage and airborne equipment and extends the service life.

[0011] Furthermore, a buffer sleeve is provided between the buffer platform and the landing gear platform, and the size of the buffer sleeve is adapted to the diameter of the inner sleeve.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the buffer sleeve and the inner sleeve are adapted to each other to form a limiting and guiding structure between the buffer plate and the landing gear platform. During takeoff and landing, the buffer sleeve slides stably along the inner sleeve, which can not only restrain the lateral sway of the buffer plate and avoid offset and imbalance, but also does not hinder the longitudinal buffer action, so that the buffer component is subjected to force more smoothly, reduce the shaking interference caused by impact, further improve the overall stability of the landing gear, and reduce the risk of rollover.

[0013] Furthermore, a keel frame is provided on the outer side of the buffer platform. There are eight keel frames in total, and the eight keel frames are arranged in a ring. The included angle between two adjacent keel frames is equal.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the keel frame on the outer side of the buffer platform is evenly distributed in a ring to form an all-round support structure. It builds a stable frame around the buffer platform, which can not only enhance the structural strength of the buffer platform, but also evenly distribute the fuselage load during takeoff and landing, effectively resist lateral forces, and avoid tilting caused by excessive force on one side. At the same time, in conjunction with the buffer components, it further improves the anti-rollover capability of the landing gear, allowing the UAV to maintain stable takeoff and landing even under complex working conditions.

[0015] Furthermore, an elastic support is provided between the keel frame and the landing gear platform. There are a total of eight elastic support components, and the eight elastic support components are correspondingly located at the bottom of the keel frame.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: the elastic support components at the bottom of the keel frame correspond one-to-one with the keel frame to form a uniformly distributed elastic support structure. During takeoff and landing, the fuselage load is transferred to the elastic support components through the keel frame. Its elastic deformation can efficiently absorb impact energy and alleviate longitudinal vibration. At the same time, in conjunction with the ring support of the keel frame, the force is more balanced, which not only enhances the buffering effect but also further improves the anti-rollover stability, reduces the stress damage to the fuselage and airborne equipment, and ensures a smooth and reliable takeoff and landing process.

[0017] Furthermore, the landing gear platform is provided with support seats, which are rectangularly distributed on the outside of the landing gear platform.

[0018] The beneficial effects of adopting the above-mentioned further solution are as follows: the support brackets on the outer side of the landing gear platform are distributed in a rectangular shape, which greatly expands the contact range between the landing gear and the ground. Its stable distribution can enhance the fit between the landing gear and the ground, improve the overall support stability, effectively resist the lateral tilting force during takeoff and landing, avoid imbalance caused by uneven ground or force deviation, and at the same time provide a stable support foundation for the landing gear, reduce fuselage sway, and further ensure the safety and reliability of the UAV takeoff and landing process.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, the landing gear platform is based on the adapter components. The inner sleeve at the center and the connecting plate are connected by a ring of elastic ropes to form a symmetrical elastic structure. During takeoff and landing, the load is transmitted to the elastic ropes through the connecting plate. Its elastic deformation can efficiently absorb impact energy. The symmetrical distribution allows the force to be evenly distributed, avoiding local stress concentration. At the same time, the limiting effect of the inner sleeve ensures that the buffering action is smooth and orderly, which not only enhances the buffering performance of the landing gear, but also improves the anti-rollover stability, providing reliable protection for the takeoff and landing of UAVs.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-5 As shown, this utility model provides a technical solution: a drone landing gear with an anti-tipping buffer structure, including a take-off and landing platform 1, and further comprising;

[0032] The adapter component 3 consists of a landing gear platform 31 located below the landing platform 1 and an inner sleeve 33. The inner sleeve 33 is located at the center of the landing gear platform 31. A connecting plate 34 is located at the center of the landing gear platform 31. Elastic ropes 35 are arranged between the connecting plate 34 and the inner sleeve 33. There are eight elastic ropes 35 in total, arranged in a ring, and the included angle between any two adjacent elastic ropes 35 is equal. The landing gear platform 31 is connected via the adapter component 3. Based on this, the inner sleeve 33 at the center is connected to the connecting plate 34 by a ring-shaped elastic rope 35, forming a symmetrical elastic structure. During takeoff and landing, the load is transmitted to the elastic rope 35 through the connecting plate 34. Its elastic deformation can efficiently absorb impact energy, and the symmetrical distribution allows the force to be evenly distributed, avoiding local stress concentration. At the same time, in conjunction with the limiting function of the inner sleeve 33, it ensures that the buffering action is smooth and orderly, which not only enhances the buffering performance of the landing gear, but also improves the anti-rollover stability, providing reliable protection for the takeoff and landing of UAVs.

[0033] A buffer assembly 2 is provided between the landing gear platform 31 and the landing platform 1. The buffer assembly 2 is composed of a buffer plate 21. The bottom of the buffer plate 21 is connected to the connecting support plate 34, and the top of the buffer plate 21 is connected to the landing platform 1. The buffer assembly 2 connects the landing gear platform 31 and the landing platform 1 through the buffer plate 21, forming a stable force transmission path. During takeoff and landing, the fuselage load is transmitted to the buffer plate 21 through the landing platform 1, and then to the connecting support plate 34. With the elastic structure of the matching assembly 3 working together to unload the force, the impact energy is effectively absorbed, the fuselage vibration is reduced, and the load is evenly distributed to avoid uneven local stress. This not only improves the stability of takeoff and landing, but also reduces the damage to the fuselage and airborne equipment, and extends the service life.

[0034] A buffer sleeve 23 is provided between the buffer platform 21 and the landing gear platform 31. The size of the buffer sleeve 23 is adapted to the diameter of the inner sleeve 33. The buffer sleeve 23 and the inner sleeve 33 are adapted to each other to form a limiting and guiding structure between the buffer platform 21 and the landing gear platform 31. During takeoff and landing, the buffer sleeve 23 slides stably along the inner sleeve 33, which can not only restrain the lateral sway of the buffer platform 21 and avoid offset and imbalance, but also does not hinder the longitudinal buffer action, so that the buffer assembly 2 is subjected to force more smoothly, reducing the swaying interference caused by impact, further improving the overall stability of the landing gear, and reducing the risk of rollover.

[0035] The outer side of the buffer platform 21 is provided with a keel frame 22. There are eight keel frames 22 in total, and the eight keel frames 22 are arranged in a ring. The included angle between two adjacent keel frames 22 is equal. The keel frames 22 on the outer side of the buffer platform 21 are evenly distributed in a ring to form an all-round support structure. They build a stable frame around the buffer platform 21, which can not only enhance the structural strength of the buffer platform 21, but also evenly distribute the fuselage load during takeoff and landing, effectively resist lateral forces, and avoid tilting caused by excessive force on one side. At the same time, in conjunction with the buffer component 2, it further improves the anti-rollover capability of the landing gear, so that the UAV can maintain stable takeoff and landing under complex working conditions.

[0036] Elastic support members 24 are provided between the keel frame 22 and the landing gear platform 31. There are eight elastic support members 24 in total, and the eight elastic support members 24 are correspondingly located at the bottom of the keel frame 22. The elastic support members 24 at the bottom of the keel frame 22 correspond one-to-one with the keel frame 22 to form a uniformly distributed elastic support structure. During takeoff and landing, the fuselage load is transferred to the elastic support members 24 through the keel frame 22. Its elastic deformation can efficiently absorb impact energy and alleviate longitudinal vibration. At the same time, in conjunction with the ring support of the keel frame 22, the force is more balanced, which not only enhances the buffering effect, but also further improves the anti-rollover stability, reduces the stress damage to the fuselage and airborne equipment, and ensures a smooth and reliable takeoff and landing process.

[0037] The landing gear platform 31 is equipped with support seats 32, which are rectangularly distributed on the outside of the landing gear platform 31. The rectangular distribution of the support seats 32 on the outside of the landing gear platform 31 greatly expands the contact range between the landing gear and the ground.
