Description

Technical Field

[0001] This invention relates to the field of cabin counterweight technology, specifically to a self-counterweight auxiliary adjustment mechanism for use in cabins. Background Technology

[0002] The center of gravity of a drone is generally located at the intersection of the diagonal lines of the propeller motors. Ensuring that the center of gravity is in a balanced position is crucial for the stable flight of the drone. Traditionally, there are two main ways to ensure that the center of gravity remains constant and that the drone can fly stably. One method is to place two fingers on the midpoint of the chord lines of the left and right wings respectively. If the nose tilts slightly forward and remains stable, the center of gravity is considered to be in a balanced position. If the drone is unstable, the positions of the internal components need to be readjusted, and counterweights need to be installed in front of or behind the drone. The components or the positions of the counterweights need to be continuously adjusted until the balance requirement is met. The other method is to install components such as the battery, flight controller, and GPS into two sliding frames inside the drone. The weight of the two sliding frames is weighed to ensure that the weight of the two sliding frames is consistent. The drone's center of gravity is found by sliding the two sliding frames left and right to change their positions.

[0003] Regardless of the method, in order to ensure the balance of the center of gravity in the cabin, a counterweight mechanism is often added to the cabin. By adjusting the counterweight mechanism, the cabin's center of gravity can be adapted to changes. However, traditional adjustment mechanisms often require manual adjustment, which is cumbersome and takes a lot of time to change the counterweight. It is difficult to achieve rapid changes in the counterweight, and the feedback mechanism is slow. Summary of the Invention

[0013] (III) Beneficial Effects This invention provides a self-balancing auxiliary adjustment mechanism for use inside a cabin. It has the following beneficial effects: 1. In this invention, the first mounting pump body is activated, drawing oil from the connected and fixed oil tank. The oil enters multiple second connecting pipes through a first connecting pipe, and then enters a first annular pipe through the multiple second connecting pipes. Based on the position of the changed center of gravity, the first valve on the corresponding third connecting pipe is opened, allowing oil to enter the corresponding third connecting pipe through the first annular pipe, and then enter the corresponding counterweight auxiliary oil tank through the third connecting pipe, increasing the weight of the counterweight auxiliary oil tank. Simultaneously, the second mounting pump body is activated, opening the second valve on the corresponding fifth connecting pipe, allowing oil from the corresponding counterweight auxiliary oil tank to enter the second annular pipe through the fifth connecting pipe, and finally enter the connected and fixed oil tank, thereby reducing the weight of the counterweight auxiliary oil tank. By increasing or decreasing the amount of oil in the counterweight auxiliary oil tank, the overall center of gravity is changed, enabling self-adjustment of the counterweight within a smaller range with better adjustment precision.

[0014] 2. In this invention, when there is a significant shift in the center of gravity within the cabin, specifically when the center of gravity shifts to the left, the third installation pump on the left side is activated, opening two third valves on the first installation pipe. Through the action of the third installation pump, oil from the connected and fixed fuel tank enters the fourth installation pipe, then flows through the third installation pipe into the first installation pipe, and finally into the interior of the two outer installation cylinders. This pushes the movable installation rod to the right, causing the rotating connecting rod to move to the right along with multiple counterweight connecting iron blocks. Simultaneously, the fourth installation pump on the right side is activated, opening two fourth valves on the second installation pipe. Through the action of the fourth installation pump, oil from the interior of the two outer installation cylinders flows through the second installation pipe into the fifth installation pipe, and finally into the connected and fixed fuel tank through the sixth installation pipe. At this point, the resetting action of the connecting installation spring inside the right outer installation cylinder causes the movable installation rod on the right side to move into the outer installation cylinder, causing the rotating connecting rod to move to the right along with multiple counterweight connecting iron blocks. This method shifts the center of gravity to the right, achieving a balance effect.

[0015] 3. In this invention, when the center of gravity shifts to the right, the fourth mounting pump on the left is activated, opening the two fourth valves on the second mounting pipe. Through the action of the fourth mounting pump, oil from the two outer mounting cylinders enters the fifth mounting pipe through the second mounting pipe, and finally enters the interior of the connecting and fixed oil tank through the sixth mounting pipe. At this time, the connecting mounting spring inside the left outer mounting cylinder resets, causing the movable mounting rod on the left to move inwards towards the outer mounting cylinder, causing the rotating connecting rod to move to the left along with multiple counterweight connecting iron blocks. Simultaneously, the third mounting pump on the right is activated, opening the two third valves on the first mounting pipe. Through the action of the third mounting pump, oil from the connecting and fixed oil tank enters the fourth mounting pipe, then enters the first mounting pipe through the third mounting pipe, and finally enters the interior of the two outer mounting cylinders through the first mounting pipe, thereby pushing the movable mounting rod to the left, causing the rotating connecting rod to move to the left along with multiple counterweight connecting iron blocks. This method allows the center of gravity to shift to the left, achieving a balance effect. Attached Figure Description

An oil reduction assembly is connected between the side wall of the fixed oil tank 3 and multiple counterweight auxiliary oil tanks 4. The oil reduction assembly includes a second mounting pump body 10 fixedly connected to the side wall of the fixed oil tank 3.

The end of the fourth connecting pipe 11 away from the second mounting pump body 10 is fixedly connected to a second annular pipe 12. Multiple fifth connecting pipes 13 are fixedly connected to the outer surface of the second annular pipe 12. The multiple fifth connecting pipes 13 are connected to multiple counterweight auxiliary oil tanks 4 one by one. A second valve is provided on the fifth connecting pipe 13. When the second mounting pump body 10 is started, the second valve on the corresponding fifth connecting pipe 13 is opened, so that the oil inside the corresponding counterweight auxiliary oil tank 4 enters the interior of the second annular pipe 12 through the fifth connecting pipe 13 and finally enters the interior of the fixed oil tank 3, thereby reducing the weight of the counterweight auxiliary oil tank 4. By increasing or decreasing the oil inside the counterweight auxiliary oil tank 4, the overall center of gravity is changed, so that the counterweight is adjusted automatically. Two support mounting plates 14 are fixedly connected to both sides of the bottom of the counterweight equipment compartment 2. Both support mounting plates 14 on the same side are fixedly connected to an outer mounting cylinder 15. A movable mounting rod 16 is provided inside the outer mounting cylinder 15. An internal piston block 17 is slidably provided inside the outer mounting cylinder 15. An installation connecting round block 18 is fixedly connected to one side of the internal piston block 17. The side of the installation connecting round block 18 away from the internal piston block 17 is fixedly connected to the movable mounting rod 16. A connecting mounting spring 19 is sleeved on the outer surface of the movable mounting rod 16. One end of the connecting mounting spring 19 is fixedly connected to the side wall of the installation connecting round block 18, and the other end of the connecting mounting spring 19 is fixedly connected to the inner wall of the outer mounting cylinder 15. The end of the movable mounting rod 16 is fixedly connected to a connecting fixing block 20. A movable counterweight assembly is connected between the two connecting fixing blocks 20. The movable counterweight assembly includes a rotating connecting long rod 21 rotatably connected between the two connecting fixing blocks 20. Multiple counterweight connecting iron blocks 22 are fixedly connected to the outer surface of the rotating connecting long rod 21. Both ends of the rotating connecting long rod 21 are fixedly connected to end movable rollers 23. Sliding long grooves 24 are opened on both sides of the inner wall of the counterweight equipment compartment 2. The end movable rollers 23 roll in contact with the inner wall of the sliding long grooves 24, thereby ensuring the stable movement of the multiple counterweight connecting iron blocks 22. A first installation pipe 25 and a second installation pipe 26 are fixedly connected between two outer mounting cylinders 15. An oil supply assembly is connected between the first installation pipe 25 and the fixed oil tank 3. The oil supply assembly includes a third installation pump body 27 fixedly connected to the bottom of the counterweight equipment compartment 2. A fourth installation pipe 29 is fixedly connected to the inlet of the third installation pump body 27. The end of the fourth installation pipe 29 away from the third installation pump body 27 is fixedly connected to the fixed oil tank 3. A third installation pipe 28 is fixedly connected to the outlet of the third installation pump body 27. The end of the third installation pipe 28 away from the third installation pump body 27 is fixedly connected to the first installation pipe 25. Two third valves are installed on the first installation pipe 25. When the center of gravity shifts to the left, the left-side third installation pump body 27 is activated, opening the two third valves on the first installation pipe 25. Through the action of the third installation pump body 27, oil from inside the fixed oil tank 3 enters the fourth installation pipe 29. Oil enters the first installation pipe 25 through the third installation pipe 28, and then enters the interior of the two outer installation cylinders 15 through the first installation pipe 25. This pushes the movable installation rod 16 to the right, causing the rotating connecting rod 21 to move to the right along with multiple counterweight connecting iron blocks 22. Simultaneously, the fourth installation pump 30 on the right side is activated, opening the two fourth valves on the second installation pipe 26. Through the action of the fourth installation pump 30, oil from inside the two outer installation cylinders 15 enters the fifth installation pipe 31 through the second installation pipe 26, and finally enters the interior of the connecting and fixed oil tank 3 through the sixth installation pipe 32. At this time, the connecting installation spring 19 inside the right outer installation cylinder 15 resets, causing the movable installation rod 16 on the right side to move into the outer installation cylinder 15, causing the rotating connecting rod 21 to move to the right along with multiple counterweight connecting iron blocks 22. In this way, the center of gravity can be shifted to the right, achieving a balance effect. A return oil assembly is connected between the second installation pipe 26 and the fixed oil tank 3. The return oil assembly includes a fourth installation pump body 30 fixedly connected to the bottom of the counterweight equipment compartment 2. The inlet of the fourth installation pump body 30 is fixedly connected to a fifth installation pipe 31. The end of the fifth installation pipe 31 away from the fourth installation pump body 30 is fixedly connected to the second installation pipe 26. The outlet of the fourth installation pump body 30 is fixedly connected to a sixth installation pipe 32. The end of the sixth installation pipe 32 away from the fourth installation pump body 30 is fixedly connected to the fixed oil tank 3. Two fourth valves are provided on the second installation pipe 26. When the center of gravity shifts to the right, the fourth installation pump body 30 on the left is activated, opening the two fourth valves on the second installation pipe 26. Through the action of the fourth installation pump body 30, the oil inside the two outer installation cylinders 15 enters the fifth installation pipe 31 through the second installation pipe 26, and finally flows through the sixth installation pipe 32. When the installation pipe 32 enters the interior of the connecting and fixing oil tank 3, the connecting installation spring 19 inside the left outer mounting cylinder 15 resets, causing the left movable installation rod 16 to move into the outer mounting cylinder 15. This causes the rotating connecting rod 21, carrying multiple counterweight connecting iron blocks 22, to move to the left. Simultaneously, the right third installation pump 27 is activated, opening the two third valves on the first installation pipe 25. Through the action of the third installation pump 27, the oil inside the connecting and fixing oil tank 3 enters the fourth installation pipe 29, then through the third installation pipe 28 into the first installation pipe 25, and then through the first installation pipe 25 into the interior of the two outer mounting cylinders 15. This pushes the movable installation rod 16 to move to the left, causing the rotating connecting rod 21, carrying multiple counterweight connecting iron blocks 22, to move to the left. In this way, the center of gravity shifts to the left, achieving a balance effect.

[0021] Working principle: In use, when there is a slight change in the center of gravity within cabin 1, the first mounting pump 5 is activated. The first mounting pump 5 draws oil from the connected and fixed oil tank 3. The oil enters multiple second connecting pipes 7 through the first connecting pipe 6, and then enters the first annular pipe 8 through the multiple second connecting pipes 7. According to the position of the changed center of gravity, the first valve on the corresponding third connecting pipe 9 is opened, and the oil enters the corresponding third connecting pipe 9 through the first annular pipe 8, and then enters the corresponding counterweight auxiliary oil tank 4 through the third connecting pipe 9, increasing the weight of the counterweight auxiliary oil tank 4. At the same time, the second mounting pump 10 is activated, and the second valve on the corresponding fifth connecting pipe 13 is opened, allowing the oil inside the corresponding counterweight auxiliary oil tank 4 to enter the second annular pipe 12 through the fifth connecting pipe 13, and finally enters the connected and fixed oil tank 3, thereby reducing the weight of the counterweight auxiliary oil tank 4. By increasing or decreasing the amount of oil inside the counterweight auxiliary oil tank 4, the overall center of gravity is changed, allowing for self-adjustment of the counterweight. When there is a significant shift in the center of gravity within cabin 1, specifically when the center of gravity shifts to the left, the third installation pump 27 on the left side is activated, opening the two third valves on the first installation pipe 25. Through the action of the third installation pump 27, oil from the fixed oil tank 3 enters the fourth installation pipe 29, then through the third installation pipe 28 into the first installation pipe 25, and finally through the first installation pipe 25 into the interior of the two outer installation cylinders 15. This pushes the movable installation rod 16 to the right, causing the rotating connecting rod 21 to move to the right along with multiple counterweight connecting iron blocks 22. Simultaneously, the fourth installation pump on the right side is activated. When the pump body 30 is activated, the two fourth valves on the second installation pipe 26 are opened. Through the action of the fourth installation pump body 30, the oil inside the two outer installation cylinders 15 enters the fifth installation pipe 31 through the second installation pipe 26, and finally enters the interior of the connecting and fixed oil tank 3 through the sixth installation pipe 32. At this time, the connecting installation spring 19 inside the right outer installation cylinder 15 resets, causing the right movable installation rod 16 to move into the outer installation cylinder 15, causing the rotating connecting rod 21 to move to the right along with multiple counterweight connecting iron blocks 22. In this way, the center of gravity can be shifted to the right to achieve a balance effect. Similarly, when the center of gravity shifts to the right, the fourth mounting pump body 30 on the left is activated, opening the two fourth valves on the second mounting pipe 26. Through the action of the fourth mounting pump body 30, the oil inside the two outer mounting cylinders 15 enters the fifth mounting pipe 31 through the second mounting pipe 26, and finally enters the interior of the connecting and fixed oil tank 3 through the sixth mounting pipe 32. At this time, the resetting action of the connecting mounting spring 19 inside the left outer mounting cylinder 15 causes the movable mounting rod 16 on the left to move into the outer mounting cylinder 15, causing the rotating connecting rod 21 to carry multiple counterweight connecting iron blocks 22. Move to the left; simultaneously, activate the third mounting pump body 27 on the right, open the two third valves on the first mounting pipe 25, and through the action of the third mounting pump body 27, allow the oil inside the fixed oil tank 3 to enter the fourth mounting pipe 29, then through the third mounting pipe 28 into the first mounting pipe 25, and through the first mounting pipe 25 into the interior of the two outer mounting cylinders 15, thereby pushing the movable mounting rod body 16 to move to the left, causing the rotating connecting rod 21 to move to the left along with multiple counterweight connecting iron blocks 22; in this way, the center of gravity can be shifted to the left, achieving a balance effect; Furthermore, the counterweight connecting iron block 22 and the counterweight auxiliary oil tank 4 can be adjusted simultaneously for further self-counterweight adjustment.
