Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and more particularly to a UAV mounting device for UAV nests. Background Technology

[0002] Most of the drones currently used for inspection, reconnaissance, and other tasks are traditional quadcopter drones that use the flight principle of helicopters. These drones can stop and go at any time, making them suitable for inspection, reconnaissance, and other tasks. However, their short range and flight time limit their efficiency and scope of operation.

[0003] Chinese patent document CN 220865682 U discloses a multi-rotor drone that solves the above-mentioned problems. However, when using this multi-rotor drone, the battery needs to be removed by pressing two spring caps at the same time so that the two limiting blocks can be disengaged from their corresponding limiting slots. However, when pressing the spring caps, the multi-rotor drone is usually unstable when docking, which makes it difficult to remove the caps smoothly. As a result, the multi-rotor drone cannot be charged or the battery can not be replaced. Summary of the Invention

[0004] This invention provides a drone fixing device for drone nests to solve the technical problem of difficulty in removing batteries from existing multi-rotor drones due to unstable docking, as described in the background art.

[0005] To address the aforementioned problems, the present invention provides a drone fixing device for drone nests, employing the following technical solution:

[0006] A drone fixing device for a drone nest includes a track for fixing the drone inside the nest and capable of moving up and down in the vertical direction. The length direction of the track is defined as the left-right direction. A pressing component is provided on the track. A holding limiting plate is symmetrically provided on the front and rear sides of the left end of the track. The two holding limiting plates and the track form a limiting space adapted to the battery end of the drone. The pressing component includes a pressing block, a connecting plate, a transmission rod, a transmission plate, and a rotation drive component. The pressing block is adjustable in position in the vertical direction and is used to press the shell of the drone's battery end. The pressing block is connected to the connecting plate, which is rotatably mounted on the track. The left end of the transmission rod is hinged to the pressing block, and the left end of the transmission plate is hinged to the right end of the transmission rod. The rotation drive component is used to drive the transmission plate to rotate.

[0007] The beneficial effects are as follows: In use, the drone fixing device for a drone nest of the present invention first drives the transmission plate to rotate via a rotary drive component. The rotation of the transmission plate drives the transmission rod to rotate, which in turn drives the connecting plate to rotate, thereby driving the pressing block to rotate. This causes the pressing block to press the end of the drone's battery into the limiting space, at which point the battery can be removed from the drone. In use, the drone fixing device for a drone nest of the present invention uses the pressing block to press the drone into the limiting space between the holding limiting plate and the track, thereby fixing the drone and facilitating the gripping mechanism to grasp the battery.

[0008] Furthermore, the rotary drive component is a pressing motor.

[0009] Beneficial effects: Automatic rotation, easy to control.

[0010] Furthermore, a reversing reducer is connected to the output shaft of the pressing motor. The output shaft of the reversing reducer extends in the front-rear direction and is connected to the right end of the transmission plate.

[0011] Beneficial effects: Improves the stability of the pressing block rotation, preventing the pressing motor from rotating too fast and damaging the drone.

[0012] Furthermore, one side of the two holding limit plates, which are arranged opposite each other, is provided with a clearance groove for avoiding the holding claws that grip the drone battery.

[0013] Furthermore, the upper right end of the holding limit plate is an arc-shaped surface, and the front and rear ends of the connecting plate are provided with notches that are adapted to the arc-shaped surface on the corresponding side, and the inner wall of the notch is in close contact with the arc-shaped surface.

[0014] Beneficial effects: Improves the stability of the connecting plate during rotation, and ensures that the holding limit plate can always support the upper part of the connecting plate, thereby improving the stability of the connecting plate and thus improving the stability of the pressing block pressing the drone.

[0015] Furthermore, a rotating hole is provided on the holding limit plate, and a rotating rod is rotatably mounted in the rotating hole. The rotating rod is connected to one side of the connecting plate.

[0016] Beneficial effects: Simple structure and easy to manufacture.

[0017] Furthermore, a limiting groove is also provided on the upper surface of the holding limiting plate, which is used to limit the housing of the drone's battery end.

[0018] Beneficial effects: Further improves the stability of the drone when pressed, preventing the drone from moving in the vertical direction.

[0019] Furthermore, the connecting plate includes a connecting part and two crank arms symmetrically distributed on the front and rear sides of the connecting part in the front-rear direction. The pressing block includes a connecting section and a pressing section. The connecting section is connected to the connecting part, and the pressing section is used to press the housing of the battery end of the drone.

[0020] Furthermore, the lower end face of the pressing section is provided with a soft pad for contacting the drone, and the lower end face of the soft pad is an inclined surface arranged from right to left upward.

[0021] Beneficial effect: Protects the drone and prevents damage from pressing the block.

[0022] Furthermore, the transmission plate has a cam-shaped structure.

[0023] Beneficial effects: Simple structure and easy to manufacture. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0035] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0036] Embodiment 1 of a drone fixing device for drone nests provided by the present invention:

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a drone fixing device for drone nests according to the present invention includes a vertical linear module mechanism, a horizontal linear module mechanism, a track 1, a gripping component, and a pressing component.

[0038] The vertical linear module mechanism is used to install inside the drone's nest.

[0039] Track 1 is located on the moving end of the vertical linear module mechanism. The length direction of track 1 is defined as the left and right direction. Both the front and rear sides of the left end of track 1 are provided with holding limit plates 2. The two holding limit plates 2 and track 1 form a limiting space that is compatible with the battery end of the drone.

[0040] The upper right side of the holding and limiting plate 2 is an arc-shaped surface 9. A rotating hole is provided on the holding and limiting plate 2, the axis of which coincides with the axis of the cylinder containing the arc-shaped surface 9. A rotating rod 10 is rotatably mounted inside the rotating hole. On one side of the two holding and limiting plates 2 arranged opposite each other, there is a clearance groove 14 for avoiding the holding claws that grip the drone battery. A limiting groove 11 is also provided on the upper surface of the holding and limiting plate 2, which is adapted to the casing at the battery end of the drone to limit the drone's movement. Each holding and limiting plate 2 also has three weight-reducing holes 15 spaced apart in the left-right direction to reduce the weight of the holding and limiting plate 2 and save materials.

[0041] The right end of the limiting groove 11 is provided with a rotating seat 19, and a rotating groove 20 is provided on the rotating seat 19. Through holes are provided on the left and right side walls of the rotating groove 20. A rotating rod is coaxially fixed in the two through holes of each rotating groove 20. A bearing is coaxially connected to the rotating rod. The rotating rod is coaxially fixed to the inner ring of the bearing. A guide wheel 21 is coaxially fixed on the outer ring of the bearing. The distance between the two guide wheels 21 and the distance between the two limiting plates are adapted to the battery end of the drone.

[0042] The horizontal linear module mechanism is located on track 1 and extends in the left and right directions.

[0043] The gripping component is located on the moving end of the horizontal linear module mechanism and is used to remove and replace the drone's battery.

[0044] The gripping assembly includes two gripping jaws and a rotary motor for driving the gripping jaws to rotate. The output shaft of the rotary motor is connected to the right end of the gripping jaws, thereby driving the right end of the gripping jaws to rotate to change the distance and space between the left ends of the two gripping jaws, thus enabling the gripping assembly to grip the battery.

[0045] Each of the two gripping claws has a top block on one side facing each other. The top blocks are set and adapted to the spring caps of the drone. In use, the two top blocks of the two gripping claws press against the two spring caps on the drone, thereby causing the battery limit block of the drone to disengage from the limit groove 11, and then the battery can be removed. After the removed battery is replaced, the battery can be directly pushed into the drone through the horizontal linear module mechanism to complete the battery replacement operation.

[0046] The pressing assembly includes a pressing block 3, a connecting plate 4, a transmission rod 5, a transmission plate 6, and a pressing motor 7.

[0047] The connecting plate 4 includes a connecting part and two crank arms 16 symmetrically distributed on the front and rear sides of the connecting part in the front-rear direction. Each crank arm 16 has a notch at the end away from the connecting part that matches the arc-shaped surface 9 on the corresponding side, and the inner wall of the notch is in close contact with the arc-shaped surface 9. The two notches are connected to the rotating rod 10 on the corresponding side.

[0048] The pressing block 3 includes a connecting section 17 and a pressing section 18. The connecting section 17 is connected to the connecting part, and the pressing section 18 is used to press the housing of the battery end of the drone. A hinge groove 13 is also provided at the connection position of the connecting section 17 and the pressing section 18.

[0049] A soft pad 12 is provided on the lower end surface of the pressing section 18 of the pressing block 3. The upper end surface of the soft pad 12 is in close contact with the lower end surface of the pressing section 18. The lower end surface of the soft pad 12 is an inclined surface arranged from right to left upward.

[0050] The left end of the transmission rod 5 is rotatably mounted in the hinge slot 13. The left end of the transmission plate 6 is hinged to the right end of the transmission rod 5. The transmission plate 6 is a cam-shaped plate.

[0051] A reversing reducer 8 is connected to the output shaft of the pressing motor 7. The output shaft of the reversing reducer 8 extends in the front-back direction and is connected to the right end of the transmission plate 6.

[0052] In use, the drone fixing device for drone nests of the present invention first moves the pressing block 3 up and down, thereby pressing the end of the drone between the two holding limit plates 2, and fixing the drone on the track 1 between the two holding limit plates 2. Then, the battery inside the drone is removed by the gripping component, and a new battery is replaced by moving it up and down along the track 1. Then, the pressing block 3 presses the drone between the two holding limit plates 2 again, and the gripping mechanism pushes the battery into the drone.

[0053] The drone fixing device for drone nests of the present invention uses a pressing block 3 to press the drone into the cavity between the holding limit plate 2 and the track 1, thereby fixing the drone and facilitating the gripping mechanism to grab the battery.

[0054] Embodiment 2 of the UAV fixing device for UAV nest provided by the present invention:
