Description

Technical Field

[0001] The present invention relates to the field of unmanned aerial vehicle (UAV) maintenance, and in particular to a top maintenance clamping device for a vehicle-mounted UAV. Background Art

[0002] A vehicle-mounted drone refers to a drone system that can be deployed and operated on a vehicle, usually consisting of a drone, its control equipment, and a vehicle-mounted platform. Vehicle-mounted drones often need to move with the carrier vehicle and perform operations frequently. Therefore, the components of the vehicle-mounted drone are easily damaged, which requires maintenance personnel to repair the vehicle-mounted drone in a timely manner. However, due to the layout of the carrier vehicle, it is inconvenient to maintain and repair the vehicle-mounted drone. Under the existing technology, maintenance personnel are generally required to place the drone on the corresponding device for fixed clamping before performing maintenance operations. However, when clamping the drone, the existing device usually adopts a simple one-way clamping and locking method, that is, a certain point of the vehicle-mounted drone is clamped by clamping tools that move against each other. The clamping effect under this method is weak, and it is easy for the vehicle-mounted drone to deflect in the unrestricted direction during the maintenance process. At the same time, direct clamping is also likely to cause certain wear and tear on the vehicle-mounted drone itself.

[0003] Therefore, in order to solve the above problems, a vehicle-mounted UAV top maintenance clamping device is developed, which performs two-way locking and limiting and avoids wear and damage caused by direct clamping. Summary of the Invention

[0004] In order to overcome the disadvantages that the existing devices usually adopt a simple one-way clamping and locking method, that is, clamping a certain point of the vehicle-mounted drone through clamping tools that move against each other, the clamping effect in this method is weak, and the vehicle-mounted drone is prone to deflection in the unrestricted direction during the maintenance process. At the same time, direct clamping is also prone to cause certain wear and tear on the vehicle-mounted drone itself. The present invention provides a vehicle-mounted drone top maintenance clamping device that performs two-way locking and limiting and avoids wear and damage caused by direct clamping.

There are two drive motors, which are respectively installed in the vertical frames on the left and right sides of the rear of the mounting frame. The output shafts of the two drive motors are arranged in opposite directions. The output shafts of the drive motors are connected to the first gear. The rear of the mounting frame is slidably connected to an upper and lower symmetrical clamping frame, and each clamping frame is connected to two mutually symmetrical racks, which are engaged with the adjacent first gears.

[0008] As a further preferred solution, it also includes a placement mechanism, which includes a mounting part. There are two mounting parts in total. The mounting parts are installed on the right side of the mounting frame in a vertically symmetrical state. A connecting rod is connected between the two mounting parts. The lower end of the connecting rod is positioned beyond the bottom side of the mounting frame. A rotating placement disk is rotatably connected to the connecting rod, and a blocking member is slidably connected to the rotating placement disk.

[0009] As a further preferred solution, it also includes a clamping mechanism, which includes a fixed column, two fixed columns, which are respectively installed on the right two sides of the corresponding clamping frame cylindrical structure, and the fixed columns are rotatably connected with a connecting plate. The lower right side of the mounting frame is connected to a second mounting seat by bolts, and the second mounting seat is internally rotatably connected with two second gears that mesh with each other, and the connecting plates are connected to the second gear on the outside. The right side of the mounting frame is slidably connected to a placement frame, and the upper and lower sides of the placement frame are also rotatably connected to connecting plates, and the connecting plates rotatably connected to the placement frame are connected to the second gear on the adjacent inner position, and the placement frame is connected to a mounting disk, and the mounting disk is slidably connected to a contact disk, and a spring is connected between the contact disk and the mounting disk.

[0015] By adopting the above technical solution

[0016] In summary, the present invention has the following advantages:

[0017] 1. During use, the present invention has a more stable clamping effect compared to traditional one-way clamping. It relies on the structural characteristics of the mounting frame to limit the wing part of the vehicle-mounted drone in the horizontal direction. At the same time, it uses an automated method to enable the clamping frame to adapt to and match the width of different wings, thereby limiting the vertical position of the wing of the vehicle-mounted drone. In addition, the design of the cylindrical structure ensures that the parts in contact with the wings are all in an arc-shaped state, which can also minimize the wear caused by the clamping state.

[0018] 2. The present invention needs to choose to use a rotating placement plate to support the tail of the vehicle-mounted drone or a blocking member to support the bottom of the vehicle-mounted drone according to the final angle state of the mounting plate. This can avoid the problem of force points being concentrated on the wings during maintenance, making the overall force of the vehicle-mounted drone more evenly distributed, and avoiding unnecessary damage to the drone.

It should be noted that, unless otherwise specified or limited, terms such as "dispose," "install," "connect," and "connect" should be understood in a broad sense. For example, "connect" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; or it may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0029] Example 1

[0030] A vehicle-mounted UAV top maintenance clamping device, such as Figure 1 As shown, it includes bases 1, 1 and 2, and the base 1 is connected to a rib for enhancing the supporting capacity, the upper part of the base 1 is rotatably connected to a mounting plate 2, the upper rear side of the mounting plate 2 is connected to a hydraulic cylinder 3, the upper rear side of the mounting plate 2 is connected to a sleeve assembly 4 for guiding the telescopic end of the hydraulic cylinder 3, the sleeve assembly 4 is located above the hydraulic cylinder 3, the rear side of the telescopic end of the hydraulic cylinder 3 is connected to a mounting frame 5, the mounting frame 5 is connected to the end of the sleeve assembly 4, the base 1 is provided with an adjusting mechanism 6 for quickly adjusting the deflection angle of the mounting plate 2 and locking it, and the mounting frame 5 is provided with a clamping mechanism 7 for dynamically clamping the wings of the drone.

[0031] It should be noted that vehicle-mounted drones are different from conventional drones. Vehicle-mounted drones are placed in carrier vehicles for a long time. Due to the layout of the carrier vehicle, it is inconvenient to maintain and repair the vehicle-mounted drone. In order to reduce this impact and improve the convenience of repairing vehicle-mounted drones, this device can be used to clamp and stabilize the vehicle-mounted drone, so that maintenance personnel can perform quick maintenance. First, the base 1 is fixedly installed at a height and position that is convenient for maintenance. Then, according to the part of the vehicle-mounted drone that needs to be repaired, the adjustment mechanism 6 is operated to adjust the angle position of the mounting plate 2. After the adjustment is completed, the wings of the vehicle-mounted drone are aligned with the opening position of the mounting frame 5. Then, the telescopic end of the hydraulic cylinder 3 is controlled to drive the mounting frame 5 to move backward, and maintain the stability of the movement under the action of the sleeve assembly 4. When the wings of the vehicle-mounted drone completely overlap with the mounting frame 5, the clamping mechanism 7 is operated to reinforce and stabilize the wings of the vehicle-mounted drone, so that the vehicle-mounted drone can maintain stability during the repair process.

[0032] like Figure 1 and Figure 2 As shown, the adjustment mechanism 6 includes a first mounting seat 61, which is mounted on the upper front side of the base 1. A worm 62 is rotatably connected to the first mounting seat 61. The worm 62 has auxiliary handles on both sides, and the auxiliary handles are provided with anti-slip grooves. A worm gear 63 that meshes with the worm 62 is connected to the front side of the part where the mounting plate 2 is rotatably connected to the base 1.

[0033] It should be noted that in order to improve the stability of the mounting plate 2 during the adjustment process and ensure the operability of the maintenance personnel, the auxiliary handles on both sides of the worm 62 can be turned to make the worm 62 start to rotate, thereby relying on the rotation transmission of the worm 62 to make the worm wheel 63 start to rotate in the corresponding direction. At this time, the worm wheel 63 will drive the mounting plate 2 to rotate in the corresponding direction, thereby achieving the effect of adjusting the maintenance angle of the vehicle-mounted drone, and in this process, relying on the self-locking effect between the worm wheel 63 and the worm 62, the mounting plate 2 can remain fixed after the adjustment is completed, thereby improving stability.

[0034] like Figure 1 and Figure 3As shown, it also includes a clamping mechanism 7, which includes a drive motor 71. There are two drive motors 71, which are respectively installed in the vertical frames on the left and right sides of the rear of the mounting frame 5. The output shafts of the two drive motors 71 are arranged in opposite directions. The output shafts of the drive motors 71 are connected to the first gear 72. The rear of the mounting frame 5 is slidably connected with a clamping frame 74 that is symmetrical up and down and used to stably clamp the wing position of the vehicle-mounted drone in the vertical direction. The clamping parts of the clamping frame 74 are all cylindrical structures, which can avoid damage to the wings of the vehicle-mounted drone. Each clamping frame 74 is connected to two mutually symmetrical racks 73, and the racks 73 are all engaged with the adjacent first gears 72.

[0035] It should be noted that after the mounting bracket 5 and the vehicle-mounted drone are overlapped, relying solely on the limiting effect of the mounting bracket 5 may cause the vehicle-mounted drone to become unstable. Therefore, in order to avoid this situation and improve the stability of the vehicle-mounted drone during the maintenance process, the two drive motors 71 can be started. As the two drive motors 71 are started, the output shafts of the drive motors 71 will begin to rotate, thereby causing the corresponding first gears 72 to enter a rotating state. When the first gears 72 begin to rotate, the corresponding racks 73 will begin to approach each other under the drive of the first gear 72, thereby causing the clamping frames 74 to begin to approach each other. Relying on the action of the clamping frames 74, the upper and lower sides of the vehicle-mounted drone are pressed and clamped, and the mounting bracket 5 is cooperated to achieve two-way clamping of the clamping frame 74 in the horizontal and vertical directions, greatly improving the stability of the vehicle-mounted drone in the maintenance state. At the same time, further adjustments can be made when the clamping frame 74 blocks the inspection position, thereby improving the flexibility of maintenance work.

[0036] Example 2

[0037] On the basis of Example 1, Figure 1 and Figure 4 As shown, it also includes a placement mechanism 8, which includes a mounting member 81. There are two mounting members 81, which are installed on the right side of the mounting frame 5 in a vertically symmetrical state. A connecting rod 82 is connected between the two mounting members 81. The lower end of the connecting rod 82 exceeds the bottom side of the mounting frame 5. A rotating placement plate 83 for supporting the tail of the vehicle-mounted drone is rotatably connected to the connecting rod 82, and a blocking member 84 for supporting the bottom of the vehicle-mounted drone is slidably connected to the rotating placement plate 83.

[0038] It should be noted that in order to further reduce the damage to the entire vehicle-mounted drone in the clamping state, it is necessary to effectively support other parts of the vehicle-mounted drone to avoid the force points being concentrated on the wings of the vehicle-mounted drone and improve the protection effect of the vehicle-mounted drone. During use, it is first necessary to perform actual operations according to the state of the mounting plate 2. When the mounting plate 2 is in a small angle tilted state or a vertical state, the blocking member 84 cannot be effectively and stably controlled due to gravity. At this time, the vehicle-mounted drone is placed in an up-and-down orientation as a whole. Therefore, it is necessary to effectively support the tail of the vehicle-mounted drone. The operator needs to rotate and adjust the position of the rotating placement plate 83 according to the position of the tail of the vehicle-mounted drone so that the rotating placement plate 83 can maintain contact with the tail to achieve support. When the mounting plate 2 is in a horizontal state or a large angle tilted state, the bottom position of the vehicle-mounted drone needs to be supported to maintain the overall support effect of the vehicle-mounted drone. At this time, it is necessary to push the blocking member 84 along the rotating placement plate 83 so that the blocking member 84 can contact with the bottom of the vehicle-mounted drone.

[0039] like Figure 1 、 Figure 5 and Figure 6 As shown, it also includes a clamping mechanism 9, which includes a fixing column 91. There are two fixing columns 91, which are respectively installed on the right two sides of the cylindrical structure of the corresponding clamping frame 74. The fixing columns 91 are rotatably connected to a connecting plate 92. The lower right side of the mounting frame 5 is connected to a second mounting seat 93 by bolts. The second mounting seat 93 is internally rotatably connected to two second gears 94 that mesh with each other. The connecting plates 92 are connected to the second gears 94 on the outside. The right side of the mounting frame 5 is slidably connected to a placement frame 95. The upper and lower sides of the placement frame 95 are also rotatably connected to connecting plates 92. The connecting plates 92 rotatably connected to the placement frame 95 are connected to the second gears 94 on the adjacent inner positions. The placement frame 95 is connected to a mounting plate 96. The mounting plate 96 is slidably connected to a contact plate 97 for adapting the wing position for clamping and fixing. A spring 98 is connected between the contact plate 97 and the mounting plate 96.

[0040] It should be noted that due to the inclined structural design of the wing, as the clamping frame 74 continues to approach, the clamping frame 74 also gets closer and closer to the outer end position of the wing. At this time, the overlapping part of the wing and the mounting frame 5 is less, and the limiting effect of the mounting frame 5 on the wing is weakened. In order to avoid this situation from affecting the maintenance of the vehicle-mounted drone, as the clamping frames 74 approach each other, the connecting plate 92 will be driven to rotate with the adjacent fixed column 91 as the rotation axis, so that the outer second gear 94 starts to rotate, and the outer second gear 94 drives the inner second gear 94 to rotate, which will cause the other connecting plate 92 to drive the placement frame 95 to slide backward, thereby causing the mounting plate 96 to move backward. At this time, the contact plate 97 follows the mounting plate 96 and moves to a position where it can contact the wing. The wing is pressed and limited by the cooperation between the contact plate 97 and the spring 98, thereby improving the stability of the clamping limit.

[0041] like Figure 1 and Figure 7 As shown, it also includes a support mechanism 10, which includes a mounting block 101. The mounting blocks 101 are connected to the front side and the left and right sides of the mounting seat. The front mounting block 101 is slidably connected to a support frame 102 for supporting the mounting plate 2.

[0042] It should be noted that in order to improve the locking ability of the mounting plate 2 and prevent the mounting plate 2 from bending due to load-bearing reasons, the support frame 102 can be used to support the mounting plate 2 in different states. In the normal state, the support frame 102 is slidingly connected to the front mounting block 101 and is in an idle state. When it needs to be used, the support frame 102 is removed from the front mounting block 101 and slidably connected to the mounting block 101 in the corresponding direction according to the deflection direction of the mounting plate 2.

[0043] like Figure 1 and Figure 8 As shown, it also includes a widening mechanism 11, and the widening mechanism 11 includes a third mounting seat 111. There are two third mounting seats 111, which are respectively installed on the left and right sides of the lower part of the base 1. The third mounting seats 111 are rotatably connected to the expansion plates 112 for increasing the ground contact area of ​​the base 1, and the expansion plates 112 are slidably connected to the push-pull rods 113 for quick locking, and the push-pull rods 113 can be snapped into place with the base 1.

[0044] It should be noted that when the device starts to clamp the vehicle-mounted drone, the overall force on the device begins to increase. In order to enhance stability and lower the overall center of gravity of the device, the push-pull rods 113 can be pulled upward first, and then the expansion plates 112 can be flipped downward 90 degrees so that the expansion plates 112 can be in the same horizontal plane as the base 1. Then, the push-pull rods 113 are pushed to reset, so that the push-pull rods 113 are engaged with the base 1, and the expansion plates 112 are locked and fixed, thereby increasing the ground contact area of ​​the base 1.

[0045] The technical principles of the embodiments of the present invention have been described above in conjunction with specific embodiments. These descriptions are intended solely to explain the principles of the embodiments of the present invention and should not be construed in any way as limiting the scope of protection of the embodiments of the present invention.
