Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicles (UAVs), and more particularly to a UAV payload bay support. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are aircraft that do not require human piloting. Payload UAVs are aircraft that do not require human piloting and can carry goods, providing new impetus for logistics and transportation. UAVs are equipped with payload bays for carrying goods, and these payload bays are mounted on the UAV via payload bay brackets. However, payload bay brackets often cannot accurately assemble the payload bay to the user's required capacity.

[0003] To address the aforementioned issues, Chinese Patent No. CN217864766U discloses a UAV payload bay support, comprising a base plate, a protective assembly, and a snap-fit ​​assembly. The base plate has a connecting plate and a fixing plate on its exterior, and several snap-fit ​​slots are formed on the base plate. The connecting plate and the fixing plate snap into the slots. The snap-fit ​​assembly, containing multiple corresponding snap-fit ​​slots, allows adjustment of the snap-fit ​​positions of the connecting plate and the fixing plate during use, thereby adjusting the load space between the fixing plate and the connecting plate.

[0004] The only adjustable feature is the distance between the fixing rod and the connecting plate, which allows for adjustment of the load compartment's capacity along the length of the base plate. However, the distance between the top wall of the connecting plate and the fixing plate and the base plate cannot be changed, thus preventing adjustment of the load space in the height direction. This aspect needs improvement. Summary of the Invention

[0005] To address the issue of the inability to adjust the capacity of the payload compartment in the height direction, this application provides a UAV payload compartment support.

[0006] The UAV payload bay bracket provided in this application adopts the following technical solution: A drone payload bay support includes: Base plate; A fixing plate is disposed on the base plate. The fixing plate includes a mounting plate and a sliding plate. The mounting plate is fixed to the base plate. The mounting plate has an opening on the side away from the base plate. The sliding plate is inserted into the mounting plate and can move within the mounting plate. A limiting mechanism is provided on the mounting plate, the sliding plate is connected to the limiting mechanism, and the limiting mechanism is used to fix the sliding plate on the mounting plate; A movable frame is disposed opposite to the fixed plate. The movable frame includes a connecting rod and two adjustable mounting rods. The two mounting rods are parallel to each other, and one end of each mounting rod is slidably connected to the base plate. The mounting rods can move towards or away from the fixed plate. The ends of the two mounting rods away from the base plate are connected by the connecting rod, and the connecting rod is connected to the sliding plate by a telescopic rod.

[0007] By adopting the above technical solution, during installation, the two mounting rods are moved simultaneously towards or away from the fixed plate, changing the length of the telescopic rod and thus altering the distance between the moving frame and the fixed plate, thereby adjusting the load space of the load chamber along the length of the base plate. Next, the sliding plate is moved towards or away from the base plate, changing the length of the sliding plate extending beyond the mounting plate, thus changing the overall height of the fixed plate. During the movement of the sliding plate, the connecting rod drives the end of the mounting rod away from the base plate to move, changing the overall length of the mounting rod. This causes the height of the fixed plate and the height of the moving frame to move synchronously, achieving adjustment of the load space in the height direction of the load chamber.

[0008] Once the sliding plate has moved to the appropriate position, a limiting mechanism is used to fix it to the mounting plate, preventing its position in the height direction from changing under gravity and increasing the stability of the load chamber structure. The above two steps can also be reversed: first adjust the load space in the height direction of the load chamber, then adjust the load space in the length direction of the base plate.

[0009] Optionally, the limiting mechanism includes a driving component and a fixing component. The driving component is mounted on the mounting plate, and the sliding plate is connected to the driving component. The sliding plate moves to drive the driving component to rotate. The fixing component is mounted on the mounting plate and can move on the mounting plate. The fixing component is used to limit the rotation of the driving component.

[0010] By adopting the above technical solution, when the sliding plate moves, it drives the drive assembly to rotate on the mounting plate. Similarly, when the drive assembly rotates, it also drives the sliding plate to move. When the sliding plate moves to a certain height, the moving fixing assembly contacts the drive assembly, thereby restricting the rotation of the drive assembly and preventing the sliding plate from moving. This achieves the fixation of the sliding plate on the mounting plate, making operation convenient.

[0011] Optionally, the driving component includes: The drive rod has a receiving groove on the inner wall of the mounting plate along the moving direction of the sliding plate. The drive rod is inserted into the receiving groove and is arranged along the length of the receiving groove. The end of the drive rod is rotatably connected to the inner wall of the receiving groove. A spiral groove is provided on the side wall of the drive rod. The drive rod is connected to the fixing assembly. A drive block is disposed on the sliding block, and the drive block is inserted into the spiral groove and moves in the spiral groove to drive the drive rod to rotate.

[0012] By adopting the above technical solution, when the sliding plate moves, it drives the driving block to move along the length of the driving rod. The inner wall of the spiral groove abuts against the side wall of the driving block, which restricts and guides the driving block, so that the driving block can only move along the trajectory of the spiral groove. The driving block moves along the length of the driving rod with the sliding plate, so that the driving block pushes the inner wall of the spiral groove to move during the movement. That is, the driving block moves relative to the spiral groove, causing the driving rod to rotate. When the fixing component restricts the rotation of the driving rod, the driving block cannot continue to move, so that the sliding plate is fixed on the mounting plate, and the height of the sliding plate is fixed.

[0013] Optionally, two limiting blocks are fixed on the inner wall of the receiving groove along the length of the drive rod. The limiting blocks are located at the opening of the receiving groove, and the two limiting blocks are arranged opposite to each other. The drive block is located between the two limiting blocks, and the side of the two limiting blocks that are close to each other abuts against the side wall of the drive block.

[0014] By adopting the above technical solution, when the sliding plate drives the driving block to move, the driving block moves between the two limiting blocks. The opposite sidewalls of the two limiting blocks contact the driving block, which plays a role in limiting and guiding the driving block, so that the driving block will not deviate during the movement, thus increasing the stability of the driving block's movement.

[0015] Optionally, the fixing component includes: The rotating gear has a fixing hole on the side of the mounting plate away from the base plate, and the rotating gear is located in the fixing hole. The rotating gear is fixed coaxially with the drive rod through a rotating rod. The crown tooth is inserted into the mounting hole and can move in the fixing hole toward or away from the base plate. The crown tooth can mesh with the rotating gear.

[0016] By adopting the above technical solution, when the load space in the height direction of the load chamber needs to be adjusted, the crown tooth is moved away from the bottom plate, so that the crown tooth is separated from the rotating gear. This allows the drive rod to drive the rotating gear to rotate around the central axis of the drive rod. In other words, the crown tooth will not interfere with the rotation of the drive rod, allowing the sliding rod to move on the mounting plate to change the load space in the height direction of the load chamber.

[0017] After the load space of the load chamber is adjusted, the crown tooth is moved closer to the bottom plate until it meshes with the rotating gear. The side wall of the upper tooth of the crown tooth abuts against the side wall of the upper tooth of the rotating gear, restricting the rotation of the rotating gear in the fixing hole. This fixes the drive rod in the mounting plate, making the drive block unable to move. Then, the sliding plate is fixed on the mounting plate, realizing the adjustment and fixation of the load space in the height direction of the load chamber.

[0018] Optionally, the mounting plate is provided with a movable component, which is located at one end of the drive rod near the base plate. The mounting rod is connected to the movable component, and the movable component can rotate on the mounting plate to drive the mounting rod to move on the base plate.

[0019] By adopting the above technical solution, when the load space of the load chamber in the length direction of the base plate needs to be adjusted, one of the mounting rods moves, driving the moving component to start, thereby driving the other mounting rod to move synchronously, so that the two mounting rods move the same distance at the same time, that is, the distance from the two mounting rods to the mounting plate is always equal, so that the load space of the load chamber changes only in the length direction of the base plate while the shape remains unchanged, thus increasing the structural stability after the load chamber is adjusted.

[0020] Optionally, the moving component includes: The movable rod has a mounting groove in the mounting plate, which is connected to one end of the receiving groove near the bottom plate. The movable rod is located in the mounting groove, and the end of the movable rod is rotatably connected to the inner wall of the mounting groove. A pull rope is provided. A movable groove is provided on the base plate along the edge trajectory of the base plate. One end of the mounting rod near the base plate is inserted into the movable groove and can move in the movable groove. One end of the pull rope is fixed to the movable rod and the other end is fixed to the mounting rod. The pull rope can be wound around the movable rod. A push spring is disposed in the moving groove. One end of the push spring is fixed to the inner wall of the moving groove, and the other end is fixed to the mounting rod. The push spring is used to push the mounting rod away from the fixed plate.

[0021] By adopting the above technical solution, rotating the moving rod causes the two pull ropes to be released from the moving rod by the same length. Under the action of the propulsion spring, the two mounting rods move simultaneously in the moving groove away from the fixed plate until the pull ropes are taut. Reversing the moving rod overcomes the elastic force of the propulsion spring, causing the pull ropes to be wound back on the moving rod by the same length. This pulls the two mounting rods simultaneously in the moving groove towards the fixed plate, changing the distance between the mounting rods and the fixed plate, thereby adjusting the load space of the load chamber in the length direction of the bottom plate.

[0022] Optionally, the drive rod is provided with a transmission assembly, the transmission assembly including: A rotating bevel gear is positioned in the mounting groove, and the rotating bevel gear is fixed coaxially with the drive rod via a transmission rod. A transmission bevel gear is disposed in the mounting groove and meshes with the rotating bevel gear. The transmission bevel gear is sleeved on the moving rod and is fixed coaxially with the moving rod.

[0023] By adopting the above technical solution, when the sliding plate drives the drive block to move, thereby adjusting the load space of the load chamber in the height direction, it also drives the drive rod to rotate, which in turn causes the rotating bevel gear to rotate, drives the transmission bevel gear to rotate, and drives the moving rod to rotate, realizing the raising and lowering of the rope, and thus realizing the movement of the installation rod on the base plate, thereby adjusting the load space of the load chamber in the length direction of the base plate. This allows for simultaneous adjustment of the load space of the load chamber in both the height direction and the length direction of the base plate, making the operation convenient.

[0024] Optionally, a slot is provided on the side wall of the sliding plate near the drive rod along the moving direction of the sliding plate. An abutment plate is inserted into the slot, and a fixing bolt is fixed on the abutment plate. The fixing bolt passes through the sliding plate and is threadedly connected to the sliding plate. The rotation of the fixing bolt drives the abutment plate to move in the slot toward or away from the drive rod. A plurality of insertion holes are provided on the side wall of the abutment plate near the drive rod. The plurality of insertion holes are evenly distributed along the length direction of the abutment plate, and the drive block can be inserted into the insertion holes.

[0025] By adopting the above technical solution, rotating the fixing bolt moves the abutment plate away from the drive rod until the abutment plate is completely housed in the slot, while the drive block is relatively pulled out of the insertion hole. At this time, when the sliding plate is moved, the drive block does not move, meaning the drive rod cannot drive the moving rod to rotate using the transmission component. This allows the load chamber to adjust the load space only in the height direction. After the load space in the height direction of the load chamber is adjusted, the fixing bolt is reversed, causing the abutment plate to move closer to the drive rod until the drive block is inserted into the insertion hole at the corresponding height. At this time, the drive rod cannot rotate under the action of the fixing component, meaning the drive block cannot move. The side wall of the drive block abuts against the inner wall of the insertion hole, thus also restricting the movement of the abutment plate. This fixes the sliding plate on the mounting plate, achieving a fixed load chamber height.

[0026] Optionally, the connecting rod includes: A connecting sleeve is fixed to the end of the telescopic rod away from the sliding plate, and the connecting sleeve is arranged along the width direction of the base plate; Two sliding rods are located at both ends of the connecting sleeve. One end of each sliding rod is inserted into the connecting sleeve and connected to it via a connecting spring. The connecting spring pulls the sliding rod toward the center of the connecting sleeve.

[0027] By adopting the above technical solution, if the base plate itself is irregularly shaped, the moving groove may not be a straight line, or there may be construction errors in the moving groove, causing the length direction of the moving groove to be non-straight, resulting in unequal spacing between the two moving grooves in the length direction. When the mounting rod moves along the trajectory of the moving groove in the moving groove, the distance between the two mounting rods will change. At this time, the sliding rod moves in the connecting sleeve, and the connecting spring pulls the sliding rod towards the center of the connecting sleeve, so that the side wall of the mounting rod that is close to each other always slides against the inner wall of the moving groove, thus satisfying the different spacing of the two moving grooves, increasing the fault tolerance of the mounting rod position adjustment, and preventing the situation of jamming in the moving groove.

[0028] In summary, this application includes at least one of the following beneficial effects: 1. During installation, move both mounting rods simultaneously towards or away from the fixed plate, changing the length of the telescopic rod and thus altering the distance between the moving frame and the fixed plate, thereby adjusting the load space of the load chamber along the length of the base plate. Next, move the sliding plate towards or away from the base plate, changing the length of the sliding plate extending beyond the mounting plate, thus changing the overall height of the fixed plate. During this movement, the sliding plate uses the connecting rod to move the end of the mounting rod away from the base plate, changing the overall length of the mounting rod. This causes the height of the fixed plate and the height of the moving frame to move synchronously, adjusting the load space of the load chamber along the height direction. 2. When the sliding plate moves, it causes the drive assembly on the mounting plate to rotate. Similarly, when the drive assembly rotates, it also drives the sliding plate to move. When the sliding plate moves to a certain height, the moving fixing assembly contacts the drive assembly, thereby restricting the rotation of the drive assembly and preventing the sliding plate from moving. This achieves the fixation of the sliding plate on the mounting plate, making operation convenient. Attached Figure Description

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0032] This application discloses a payload bay support for an unmanned aerial vehicle (UAV). (Refer to...) Figure 1 and Figure 2 The UAV payload bay support includes a base plate 10, a fixed plate 20, and a movable frame 30. The base plate 10 is placed horizontally. The fixed plate 20 includes a mounting plate 21 and a sliding plate 22. The mounting plate 21 is vertically arranged and fixed to one end of the base plate 10 along its length. The top wall of the mounting plate 21 is an open structure. The sliding plate 22 is vertically inserted into the mounting plate 21 and can move on the mounting plate 21. The movable frame 30 is located on the upper surface of the base plate 10. The movable frame 30 includes a connecting rod 32 and two mounting rods 31. The two mounting rods 31 are vertically arranged, and the plane containing the two mounting plates 21 is parallel to the mounting plates 21.

[0033] Reference Figure 2 and Figure 3 The upper surface of the base plate 10 has a moving groove 11 at the edge of the base plate 10 along its length. The moving groove 11 is arranged along the trajectory of the base plate 10. The bottom end of the mounting rod 31 is fixed with a positioning rod 311. The positioning rod 311 is inserted into the moving groove 11 and can move in the moving groove 11. The mounting rod 31 is a telescopic sleeve rod, that is, the length of the mounting rod 31 in the vertical direction can be changed.

[0034] Reference Figure 2 and Figure 3The connecting rod 32 is located at the top of the mounting rod 31. The connecting rod 32 includes a connecting sleeve 321 and two sliding rods 322. The connecting sleeve 321 is horizontally arranged and located between the two mounting rods 31. The end of the connecting rod 32 is aligned with the mounting rod 31. The two sliding rods 322 are respectively inserted into the two ends of the connecting sleeve 321. The connecting sleeve 321 is provided with two connecting springs 323. One end of the connecting spring 323 is fixedly connected to the inner wall of the connecting sleeve 321, and the other end is fixed to the sliding rod 322. It is used to pull the sliding rod 322 towards the center of the connecting sleeve 321. The end of the sliding rod 322 that extends out of the connecting sleeve 321 is fixedly connected to the top of the mounting rod 31. The top wall of the connecting sleeve 321 is flush with the top wall of the sliding plate 22.

[0035] During installation, the two mounting rods 31 are moved simultaneously toward or away from the fixed plate 20, changing the distance between the moving frame 30 and the fixed plate 20, thereby adjusting the load space of the load chamber along the length of the base plate 10. In this embodiment, the base plate 10 itself is irregularly shaped, meaning the moving groove 11 is not a straight line. When the mounting rods 31 move along the trajectory of the moving groove 11, the distance between the two mounting rods 31 changes. At this time, the sliding rod 322 moves in the connecting sleeve 321, and the connecting spring 323 pulls the sliding rod 322 toward the center of the connecting sleeve 321, so that the sidewalls of the mounting rods 31 that are close to each other always slide against the inner wall of the moving groove 11, satisfying the different spacing of the two moving grooves 11, increasing the fault tolerance of the mounting rod 31 position adjustment, and preventing jamming in the moving groove 11.

[0036] Next, the sliding plate 22 is adjusted up and down, changing the length of the sliding plate 22 extending beyond the mounting plate 21, thus changing the overall height of the fixed plate 20. During the movement of the sliding plate 22, the connecting rod 32 is simultaneously driven to move the end of the mounting rod 31 away from the base plate 10, changing the overall length of the mounting rod 31. This ensures that the top wall of the sliding plate 22 remains flush with the top wall of the connecting sleeve 321, achieving adjustment of the load space in the height direction of the load compartment. These two steps can also be reversed, i.e., first adjusting the load space in the height direction of the load compartment, then adjusting the load space in the length direction of the load compartment on the base plate 10.

[0037] Reference Figure 1 and Figure 2Once the load space is determined, the upper cover 110 is fixed between the mounting rod 31 and the fixing plate 20 with bolts. The cover 110 is vertically set and covers the space formed by the fixing plate 20, the bottom plate 10 and the mounting rod 31. The hatch 120 is hinged to the connecting sleeve 321 by a hinge. The hatch 120 can rotate to a horizontal state, and the side of the hatch 120 away from the connecting sleeve 321 can abut against the sliding plate 22 to cover the space between the connecting sleeve 321 and the sliding plate 22. At this time, the top wall of the cover 110 contacts the hatch 120, so that the area between the fixing plate 20 and the moving frame 30 is covered by the hatch 120, the two covers 110 and the bottom plate 10. The load space is the area enclosed by the horizontally placed hatch 120, the two covers 110, the fixing plate 20 and the bottom plate 10, which can protect the items in the load space. A tie rod is bolted to the mounting rod 31. The end of the tie rod away from the mounting rod 31 is bolted to the base plate 10, thus supporting the mounting rod 31 and increasing the stability of the movable frame 30 structure. Reference Figure 2 and Figure 3 In order to drive the connecting rod 32 to move synchronously when the sliding plate 22 moves, so that the height of the fixed plate 20 and the height of the moving frame 30 are always equal, and thus the telescopic rod 40 is always in a horizontal state, that is, the top wall of the load chamber will not tilt, a telescopic rod 40 is provided between the sliding plate 22 and the connecting sleeve 321. The telescopic rod 40 is horizontally set, one end of the telescopic rod 40 is fixed to the sliding plate 22, and the other end is fixed to the connecting sleeve 321. The telescopic rod 40 is a telescopic sleeve rod, so that the distance between the sliding plate 22 and the connecting sleeve 321 can be changed, that is, the telescopic rod 40 will not interfere with the movement of the mounting rod 31 on the base plate 10.

[0038] When the sliding plate 22 moves, it drives the telescopic rod 40 to move up and down, which in turn moves the connecting rod 32, thereby moving the end of the mounting rod 31 away from the base plate 10. This causes the overall length of the mounting rod 31 to change, thus making the height of the fixed plate 20 and the height of the moving frame 30 move synchronously.

[0039] Reference Figure 4 and Figure 5When the sliding plate 22 moves to an appropriate height, in order to prevent the position of the sliding plate 22 from changing in the height direction under the action of gravity, a limiting mechanism 50 is provided on the mounting plate 21. The limiting mechanism 50 includes a driving assembly 51 and a fixing assembly 52. ​​The driving assembly 51 is provided on the mounting plate 21, and the sliding plate 22 is connected to the driving assembly 51. The driving assembly 51 includes a driving rod 511 and a driving block 512. A receiving groove 211 is provided vertically on the inner wall of the mounting plate 21. The driving rod 511 is vertically provided in the receiving groove 211, and the end of the driving rod 511 is rotatably connected to the inner wall of the receiving groove 211. A spiral groove 5111 is provided circumferentially on the side wall of the driving rod 511. The driving block 512 is horizontally provided, and one end of the driving block 512 is provided on the sliding plate 22, and the other end extends into the receiving groove 211 and is inserted into the spiral groove 5111.

[0040] Reference Figure 4 and Figure 6 Two limiting blocks 60 are fixed vertically on the inner wall of the receiving groove 211. The limiting blocks 60 are located at the opening of the receiving groove 211 near the sliding plate 22. The two limiting blocks 60 are arranged opposite each other, and the driving block 512 is located between the two driving blocks 512. The side of the two limiting blocks 60 that are close to each other is in contact with the side wall of the driving block 512.

[0041] When the sliding plate 22 moves, it drives the driving block 512 to move along the length of the driving rod 511. The inner wall of the spiral groove 5111 abuts against the side wall of the driving block 512, which restricts and guides the driving block 512, so that the driving block 512 can only move along the trajectory of the spiral groove 5111. The driving block 512 is restricted by the two limit blocks 60, so that the driving block 512 can only move vertically with the sliding plate 22. Thus, the driving block 512 pushes the inner wall of the spiral groove 5111 to move during the movement. That is, the driving block 512 moves relative to the spiral groove 5111, so that the driving rod 511 rotates in the receiving groove 211 about the central axis of the driving rod 511.

[0042] Reference Figure 4 and Figure 7The fixing component 52 includes a rotating gear 521 and a crown tooth 522. A fixing hole 212 is provided on the top wall of the mounting plate 21. The rotating gear 521 is horizontally placed in the fixing hole 212. A rotating rod 5211 is coaxially fixed to the rotating gear 521. The rotating rod 5211 is vertically arranged, and its bottom end passes through the mounting plate 21 into the receiving groove 211 and is coaxially fixed to the top end of the drive rod 511. The crown tooth 522 is inserted into the fixing hole 212 and can mesh with the rotating gear 521. A guide block 5221 is fixed on the side wall of the crown tooth 522. A guide groove 2121 is provided vertically on the inner wall of the fixing hole 212. The guide block 5221 is inserted into the guide groove 2121 and moves within the guide groove 2121, so that the crown tooth 522 moves only in the vertical direction.

[0043] When the load space in the height direction of the load chamber needs to be adjusted, the crown tooth 522 is moved away from the base plate 10, so that the crown tooth 522 is separated from the rotating gear 521. This allows the drive rod 511 to drive the rotating gear 521 to rotate around the central axis of the drive rod 511. That is, the crown tooth 522 will not interfere with the rotation of the drive rod 511, allowing the sliding rod 322 to move on the mounting plate 21 to change the load space in the height direction of the load chamber.

[0044] Reference Figure 4 and Figure 7 After the load space of the load chamber is adjusted, the crown tooth 522 is moved towards the base plate 10 until the crown tooth 522 meshes with the rotating gear 521. The side wall of the upper tooth of the crown tooth 522 abuts against the side wall of the upper tooth of the rotating gear 521, restricting the rotation of the rotating gear 521 in the fixing hole 212, thereby fixing the drive rod 511 in the mounting plate 21, so that the drive block 512 cannot move, and then fixing the sliding plate 22 on the mounting plate 21, thereby realizing the adjustment and fixing of the load space in the height direction of the load chamber.

[0045] Reference Figure 4 and Figure 5 In order to adjust the length of the load chamber when adjusting the height of the load chamber, a movable component 70 is provided on the mounting plate 21. The movable component 70 can rotate on the mounting plate 21. The movable component 70 is connected to the drive rod 511 through the transmission component 80. At the same time, the movable component 70 is also connected to the mounting rod 31. When the drive rod 511 rotates, it drives the transmission component 80 to start, thereby driving the movable component 70 to rotate and driving the mounting rod 31 to move in the movable slot 11.

[0046] Reference Figure 5 and Figure 8The moving assembly 70 includes a moving rod 71, a pull rope 72, and a propulsion spring 73. A mounting groove 213 is formed in the mounting plate 21, located below and communicating with the receiving groove 211. The moving rod 71 is horizontally positioned in the mounting groove 213 and perpendicular to the central axis of the base plate 10. The end of the moving rod 71 is rotatably connected to the inner wall of the mounting groove 213. One end of the pull rope 72 is fixed to the side wall of the moving rod 71, and the other end passes through the mounting plate 21 into the moving groove 11 and is fixed to the mounting rod 31. The pull rope 72 can be wound around the moving rod 71. The propulsion spring 73 is located in the moving groove 11, between the mounting rod 31 and the mounting plate 21. One end of the propulsion spring 73 is fixed to the inner wall of the moving groove 11, and the other end is fixed to the mounting rod 31, used to propel the mounting rod 31 away from the mounting plate 21.

[0047] Reference Figure 4 and Figure 5 The transmission assembly 80 includes a rotating bevel gear 81 and a transmission bevel gear 82. The rotating bevel gear 81 is horizontally placed in the mounting groove 213, and a transmission rod 811 is coaxially fixed to the rotating bevel gear 81. The transmission rod 811 is vertically arranged, and its top end passes through the mounting plate 21 and extends into the receiving groove 211, so that the top end of the transmission rod 811 is fixedly connected to the bottom end of the drive rod 511. The transmission bevel gear 82 is vertically arranged in the mounting groove 213, and is sleeved on the moving rod 71 and coaxially fixed with the moving rod 71. The rotating bevel gear 81 meshes with the transmission bevel gear 82. When the sliding plate 22 moves the drive block 512 to adjust the load space of the load chamber in the height direction, it also drives the drive rod 511 to rotate, thereby causing the rotating bevel gear 81 to rotate, driving the transmission bevel gear 82 to rotate, and driving the moving rod 71 to rotate. This causes the two pull ropes 72 to be released from the moving rod 71 by the same length. Under the action of the propulsion spring 73, the two mounting rods 31 move simultaneously in the moving groove 11 away from the fixed plate 20 until the pull ropes 72 are taut. Then, the moving rod 71 is reversed to overcome the elastic force of the propulsion spring 73, causing the pull ropes 72 to be wound back on the moving rod 71 by the same length. This pulls the two mounting rods 31 to move simultaneously in the moving groove 11 towards the fixed plate 20, changing the distance between the mounting rods 31 and the fixed plate 20, thereby adjusting the load space of the load chamber in the length direction of the base plate 10.

[0048] Reference Figure 4 and Figure 5When the pull rope 72, carrying the mounting rod 31, reaches the appropriate position, i.e., the length of the load chamber is determined, but the height of the load chamber still needs adjustment, a slot 221 is vertically provided on the side wall of the sliding plate 22 near the drive rod 511. An abutment plate 90 is fitted into the slot 221. A fixing bolt 222 is fixed on the side of the abutment plate 90 away from the drive rod 511. The fixing bolt 222 is horizontally positioned, and the end of the fixing bolt 222 away from the abutment plate 90 passes through the sliding plate 22. The fixing bolt 222 is threadedly connected to the sliding plate 22. The fixing bolt 222 is located at the top of the sliding plate 22, and the sliding plate 22 is not completely retracted onto the mounting plate 21 due to the influence of the telescopic rod 40, thus preventing interference during the up-and-down movement of the sliding plate 22. The side wall of the abutment plate 90 near the drive rod 511 has several insertion holes 91. The insertion holes 91 are evenly arranged in the vertical direction, and the drive block 512 can be inserted into the insertion holes 91.

[0049] When only the height of the load compartment needs to be adjusted, rotating the fixing bolt 222 moves the abutment plate 90 away from the drive rod 511 until the abutment plate 90 is fully retracted into the slot 221, and the drive block 512 is pulled out of the insertion hole 91. At this time, when the sliding plate 22 is moved, the drive block 512 does not move, that is, the drive rod 511 cannot drive the moving rod 71 to rotate using the transmission component 80, so that the load compartment can only be adjusted in the height direction of the load space. After the load space in the height direction of the load compartment is adjusted, the fixing bolt 222 is reversed, causing the abutment plate 90 to move closer to the drive rod 511 until the drive block 512 is inserted into the insertion hole 91 at the corresponding height. At this time, the drive rod 511 cannot rotate under the action of the fixing component 52, that is, the drive block 512 cannot move, and the side wall of the drive block 512 abuts against the inner wall of the insertion hole 91, thus also restricting the movement of the abutment plate 90, thereby fixing the sliding plate 22 to the mounting plate 21, realizing the fixation of the load compartment height.

[0050] The implementation principle of the UAV payload bay bracket in this embodiment is as follows: During installation, two mounting rods 31 are simultaneously moved closer to or further away from the fixed plate 20, changing the length of the telescopic rod 40. This alters the distance between the moving frame 30 and the fixed plate 20, thereby adjusting the load space of the payload bay along the length of the base plate 10. Next, the sliding plate 22 is moved closer to or further away from the base plate 10, changing the length of the sliding plate 22 extending beyond the mounting plate 21, thus changing the overall height of the fixed plate 20. During this movement, the sliding plate 22 uses the connecting rod 32 to move the end of the mounting rod 31 away from the base plate 10, changing the overall length of the mounting rod 31. This causes the height of the fixed plate 20 and the height of the moving frame 30 to move synchronously, adjusting the load space of the payload bay along its height.

[0051] Once the load space is determined, the upper cover 110 is fixed between the mounting rod 31 and the fixing plate 20 with bolts. The cover 110 is vertically set and covers the space formed by the fixing plate 20, the bottom plate 10 and the mounting rod 31. The hatch 120 is hinged to the connecting sleeve 321 by a hinge. The hatch 120 can rotate to a horizontal position, and the side of the hatch 120 away from the connecting sleeve 321 can abut against the sliding plate 22 to cover the space between the connecting sleeve 321 and the sliding plate 22. At this time, the top wall of the cover 110 contacts the hatch 120, so that the area between the fixing plate 20 and the moving frame 30 is covered by the hatch 120, the two covers 110 and the bottom plate 10. The load space is the area enclosed by the horizontally placed hatch 120, the two covers 110, the fixing plate 20 and the bottom plate 10, which can protect the items in the load space.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
