Description

Technical Field

[0001] This utility model relates to the field of item storage technology, specifically a storage arm tray system for a large-load multi-rotor drone. Background Technology

[0002] Due to their payload requirements, heavy-duty multi-rotor drones have large arm structures and high weight. During the modular storage and transportation process, the arms are susceptible to external impacts, displacement, and collisions, which can cause structural damage and deformation, severely affecting the drone's performance and lifespan.

[0003] Chinese patent CN210122122U discloses a multi-rotor drone storage box that stores detached drone arms in a detachable rotor arm storage slot. However, the drone arms in this design can only be placed in the storage slot in one direction, resulting in low space utilization. The size of the storage slot is fixed, which can only accommodate drone arms of a fixed model. The electronic contacts at the end of the arm are in direct contact with the inner wall of the storage slot, which is easily scratched and leads to poor electrical contact. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a retractable arm tray system for heavy-duty multi-rotor drones. The rotor end bracket on one support plate supports and fixes the rotor seat of the arm, while the plug-in end bracket on another support plate clamps and fixes the arc-shaped sidewall of the plug-in rod. The rotor end bracket and plug-in end bracket on the support plate are alternately arranged, and adjacent arms are placed and fixed in opposite directions, making full use of space and achieving a more balanced weight distribution. At the same time, the distance between the two support plates can be adjusted to accommodate drone arms of different lengths.

[0005] To achieve the aforementioned objective of a retractable arm tray system for heavy-duty multi-rotor UAVs, this utility model provides the following technical solution: A retractable arm tray system for a heavy-duty multi-rotor UAV includes a base plate and a slide plate located between the landing gears. The base plate and the slide plate are slidably connected. The upper part of the base plate and the slide plate is used to store and place the UAV arm. The arm includes a rotor mount and a connector rod. A support plate is fixedly connected to the upper surface of the base plate and the slide plate. The two support plates are arranged parallel to each other. Rotor end holders and connector end holders are alternately arranged along the length direction on the support plates. The rotor end holders and connector end holders on the two support plates are positioned corresponding to each other. The rotor mount and connector rod of the UAV arm are respectively engaged with the corresponding rotor end holders and connector end holders on the two support plates.

[0006] Furthermore, the rotor end holder is a slotted structure formed on the upper surface of the support plate to radially position the rotor seat of the arm. The sidewall of the slot is open in the direction of the corresponding insertion end holder to facilitate the passage of the folded rotor.

[0007] Furthermore, the connector holder is a U-shaped structure with the opening facing upwards, and the upper edge of the U-shaped connector holder is provided with an arc-shaped guide surface to guide the insertion of the connector rod.

[0008] Furthermore, multiple parallel guide posts are fixedly connected to the side wall of the skateboard facing the base plate. The length direction of the guide posts is towards the base plate, and multiple guide holes are opened at corresponding positions on the base plate. The radius of the guide posts is matched with the inner diameter of the guide holes, and the guide posts slide within the guide holes.

[0009] Furthermore, both the base plate and the skateboard utilize a high-strength, lightweight alloy frame.

[0010] Furthermore, the inner wall of the rotor end bracket is bonded with a shock-absorbing pad, and the inner walls on both sides of the U-shaped plug-in end bracket are provided with elastic pads.

[0011] Furthermore, anti-slip pads are glued to the bottom of both the base plate and the skateboard.

[0012] Compared with the prior art, this utility model provides a retractable arm tray system for heavy-duty multi-rotor UAVs, which has the following advantages: 1. This is a large-payload multi-rotor drone arm storage tray system. By placing adjacent arms in opposite directions and fixing them on the support plate, the space utilization is higher, the weight is more balanced, the whole tray system is more stable, the distance between the two support plates can be adjusted, and the direction of movement of the support plates is adapted to the orientation of the drone landing gear, which can accommodate arms of different lengths.

[0013] 2. The rotor mount stands vertically inside the rotor end holder, further saving horizontal space. For heavy-load multi-rotor drones, multiple arms can be placed and fixed on one layer. The slotted structure of the rotor end holder wraps around the outside of the rotor mount for radial fixation, preventing the arms from wobbling horizontally. The corresponding positions on the sidewalls of the slots are open to facilitate the passage of folded rotors.

[0014] 3. The connector holder has an upward-facing U-shaped structure that clamps and fixes the cylindrical sidewall of the connector rod, preventing it from contacting the electronic contacts at the end of the connector rod, thus ensuring greater safety. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] Please see Figure 1 and Figure 2 This is a large-payload multi-rotor UAV arm storage tray system, which includes a base plate 2 and a slide plate 3 located between the landing gear. The base plate 2 and the slide plate 3 are slidably connected. The upper part of the base plate 2 and the slide plate 3 is used to store and place the UAV arm. The arm includes a rotor seat 10 and a connector rod 9. A support plate 4 is fixedly connected to the upper surface of the base plate 2 and the slide plate 3. The two support plates 4 are arranged parallel to each other. Rotor end brackets 6 and connector end brackets 5 are alternately arranged on the support plates 4 along the length direction. The rotor end brackets 6 and connector end brackets 5 on the two support plates 4 are positioned corresponding to each other. The rotor seat 10 and connector rod 9 of the arm are respectively engaged with the corresponding rotor end brackets 6 and connector end brackets 5 on the two support plates 4. The tray system is placed between the landing gears of a heavy-duty multi-rotor UAV. The length of the base plate 2 is less than the distance between the two landing gears, making full use of the internal cavity of the landing gear. The moving direction of the slide plate 3 is adapted to the direction of the landing gear. The landing gear does not affect the movement of the slide plate 3. After the slide plate 3 moves, the distance between the slide plate 3 and the support plate 4 on the base plate 2 changes to accommodate UAV arms of different lengths. The rotor end bracket 6 and the plug-in end bracket 5 on the support plate 4 are alternately set. The rotor seat 10 of the arm is on one support plate 4 and is fixed by the rotor end bracket 6. The plug-in rod 9 of the arm is on another support plate 4 and is fixed by the plug-in end bracket 5. Adjacent arms are placed in opposite directions on the support plates 4 to make full use of the horizontal space between the UAV landing gears.

[0019] Preferably, the rotor end holder 6 is a slotted structure formed on the upper surface of the support plate 4 to radially position the rotor seat 10 of the arm. The sidewall of the slot is open in the direction of the corresponding insertion end holder 5 to allow the folded rotor to pass through. The rotor end holder 6 is used to fix the rotor seat 10. The shape of the slotted structure is consistent with the shape of the rotor seat 10 for better fixation. When placing it, the rotor rotation direction on the rotor seat 10 is aligned with the direction of the insertion rod 9. The rotor seat 10 is placed downward from above the slotted structure. The rotor seat 10 cannot move horizontally. An annular protrusion is provided at the bottom of the slotted structure to support and elevate the rotor seat 10, so as to prevent the folded rotor from being squeezed and deformed by the upper surface of the slide plate 3 and the base plate 2. One sidewall of the slot is open, so that when the rotor seat 10 is placed downward into the slot, the opening allows the rotor to pass through from top to bottom without being blocked by the sidewall of the slot.

[0020] Preferably, the connector holder 5 is a U-shaped structure with the opening facing upwards. The upper edge of the U-shaped connector holder 5 has an arc-shaped guide surface to guide the insertion of the connector rod 9. The connector rod 9 is in a horizontal state with its cylindrical outer wall facing downwards. It is pressed into the upper opening of the U-shaped connector holder 5 to fix the connector rod 9 horizontally. The upper opening of the connector holder 5 has an arc-shaped guide surface, which facilitates the insertion of the connector rod 9 into the connector holder 5 from top to bottom, and the electronic contacts at the end of the connector rod 9 will not be touched.

[0021] Preferably, multiple parallel guide posts 7 are fixedly connected to the side wall of the slide plate 3 facing the base plate 2. The length direction of the guide posts 7 is towards the base plate 2. Multiple guide holes 8 are opened at corresponding positions on the base plate 2. The radius of the guide posts 7 is adapted to the inner diameter of the guide holes 8, and the guide posts 7 slide within the guide holes 8. When a longer drone arm needs to be placed, the slide plate 3 is pulled away from the base plate 2, and the guide posts 7 slide out from the guide holes 8. The distance between the two support plates 4 increases, that is, the distance between the plug-in end bracket 5 and the rotor end bracket 6 increases, which can be used to fix a longer arm. At the same time, the multiple parallel guide posts 7 ensure that the two support plates 4 are always in a parallel state, and the positions of the plug-in end bracket 5 and the rotor end bracket 6 are always corresponding without error.

[0022] Preferably, both the base plate 2 and the slide plate 3 are made of high-strength, lightweight alloy frames. This ensures that the base plate 2 and the slide plate 3 have sufficient load-bearing capacity.

[0023] Preferably, the inner wall of the rotor end bracket 6 is bonded with a shock-absorbing pad, and the inner walls on both sides of the U-shaped plug-in end bracket 5 are provided with elastic gaskets. The rotor seat 10 is better fixed inside the rotor end bracket 6 due to the buffering effect of the shock-absorbing pad, and will not be squeezed or damaged. The plug rod 9 is pressed into the U-shaped plug-in end bracket 5, and the elastic gaskets ensure better fixation of the plug rod 9 and prevent it from lifting up from above.

[0024] Preferably, anti-slip pads are adhered to the bottom of both the base plate 2 and the slide plate 3. After the drone arm is placed on the support plate 4, the base plate 2 and the slide plate 3 are positioned between the drone landing gear. The anti-slip pads ensure that the base plate 2 and the slide plate 3 are stably placed between the drone landing gear and will not slide completely, causing a collision.

[0025] Working principle: Place the base plate 2 in the correct position, pull the slide plate 3, adjust the distance between the two support plates 4 to a suitable distance, place the drone arm downward on the support plate 4, put the rotor seat 10 of the arm into the rotor end bracket 6, and at the same time press the plug rod 9 into the U-shaped plug end bracket 5. The adjacent arms are placed in opposite directions. Finally, place the drone so that the base plate 2 is located in the cavity inside the drone landing gear.
