Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a battery-swapping UAV. Background Technology

[0002] Unmanned aerial vehicles (UAVs) refer to aircraft that fly within the atmosphere without a human pilot, through remote control, autonomous control, or human-machine collaboration. Battery-swapping UAVs are industrial-grade drones that overcome range limitations by enabling rapid battery replacement via automated hangars and robotic arm systems. Essentially, they transform the traditional charging and waiting process into a "swap-and-go" energy replenishment mode. Battery-swapping UAVs are also a very common piece of equipment used in dam area hazard inspections.

[0003] Application number 202110304993.1 discloses a drone, comprising a body and a drive unit. The upper part of the body has an upper cover assembly, and the lower part of the body has a lower cover. A support device is installed under the lower cover. Connecting arms extend outward from the four corners of the body's sides, and the drive unit is hinged to the connecting arms. This invention, by incorporating a parachute and a foldable drive unit, not only achieves power-off and drop protection but also facilitates easy storage. It features a simple structure and good practicality.

[0004] While the above comparison documents may make it easier to store some components, the drone lands by contacting the ground with its bottom support legs. The excessive pressure on each of the columnar support legs makes it easy to sink into wetlands or mud, and it may tip over when encountering uneven surfaces, resulting in insufficient stability of the battery-swapping drone. Utility Model Content

[0005] The purpose of this invention is to provide a battery-swapping drone to solve the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a battery-swapping drone, comprising a drone body, a drone frame, and fan blades. The drone frame is bolted to the outer wall of the drone body, and fan blades are connected to the outer side of the drone frame. Fixed plates are connected to both sides of the bottom end of the drone body, and support feet are welded to the middle of the bottom end of the fixed plates. An electric push rod is installed at the bottom of the inner wall of the support foot, and a lifting seat is connected to the output end of the electric push rod. Transmission plates are rotatably connected to both sides of the outer wall of the lifting seat, and a base is rotatably connected to the bottom of the outer wall of the transmission plates. A base plate is connected to the bottom of the outer wall of the base.

[0007] The extension of the electric push rod drives the lifting base to move up and down, thus determining whether the base is in a retracted or extended state.

[0008] Preferably, a No. 1 spring is fixedly connected to the middle of the top of the lifting seat, and the top of the outer wall of the No. 1 spring is connected to the top of the inner wall of the support foot. A movable groove is opened in the middle of the outer wall of the support foot, and the two sides of the outer wall of the lifting seat extend into it.

[0009] The lifting seat moves upward by resetting the first spring.

[0010] Preferably, the outer walls of the fixing plate are internally threaded with threaded pins on both sides, the bottom of the drone body is provided with threaded holes and the threaded pins extend into them, and the fixing plate and the support feet form a "T" shape.

[0011] The support feet are fixed in place by a fixed plate, and subsequent replacement of the support feet can be completed simply by unscrewing the threaded pin.

[0012] Preferably, a slide is welded to the middle of the outer wall of the base, and the base, bottom plate and slide form a "U" shape, and a fixed column is slidably connected to the outer wall of the slide.

[0013] The base plate moves linearly by being guided by a slide.

[0014] Preferably, the bottom end of the outer wall of the fixed column is provided with a sliding groove corresponding to the base, one side of the outer wall of the fixed column is welded to the bottom end of the support foot, and the support foot and the fixed column form a "T" shape.

[0015] Preferably, a limiting seat is connected to the top of the outer wall of the slide block, and the limiting seat has a "T" shaped structure. The transmission plate, the fixed column and the support foot form a triangular stabilizing mechanism.

[0016] The slide is guided to move linearly by a limit seat, and the structural stability is improved by a triangular stabilizing mechanism.

[0017] Preferably, a second spring is fixedly connected to the middle of the outer wall of the slide block, and a guide groove is provided at the top of the outer wall of the fixed column, into which the limiting seat extends.

[0018] The base is reset by using spring number two.

[0019] Preferably, a battery box is installed at the bottom center of the drone body, and a power source is connected inside the battery box. An end cap is connected to one side of the outer wall of the power source, and a handle is installed at the center of the outer wall of the end cap.

[0020] Battery swapping is achieved by removing the power source from the battery compartment.

[0021] As can be seen from the above, the battery-swapping drone provided by this utility model has the following beneficial effects.

[0022] 1. By keeping the base plates far apart, the error in the deployment position can be reduced, the support area between the support feet and the ground can be increased, and at this time, the transmission plate, the fixed column and the support feet form a triangular stabilizing mechanism, thereby increasing the support area during landing, preventing the drone from sinking and tipping over, and reducing maintenance costs caused by tipping over.

[0023] 2. By moving the base plate closer to the support feet, the space occupied by the landing support components can be reduced, thus lowering the probability of collisions during flight.

[0024] 3. The support feet are fixed in place by the fixing plate, so that the support feet can be replaced simply by turning off the threaded pin. Attached Figure Description

[0035] 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.

[0036] Please see Figures 1-9 This utility model provides a technical solution: a battery-swapping drone, including a drone body 1, a drone frame 2, and fan blades 3. The drone frame 2 is bolted to the outer wall of the drone body 1, and the fan blades 3 are connected to the outer side of the drone frame 2. Fixing plates 4 are connected to both sides of the bottom end of the drone body 1, and support feet 6 are welded to the middle of the bottom end of the fixing plates 4. An electric push rod 7 is installed on the bottom end of the inner wall of the support foot 6, and the output end of the electric push rod 7 is connected to a lifting seat 8. Transmission plates 10 are rotatably connected to both sides of the outer wall of the lifting seat 8, and the transmission... A base 11 is rotatably connected to the bottom of the outer wall of the movable plate 10, and a base plate 12 is connected to the bottom of the outer wall of the base 11; a first spring 9 is fixedly connected to the middle of the top of the lifting seat 8, and the top of the outer wall of the first spring 9 is connected to the top of the inner wall of the support foot 6. A movable groove is opened in the middle of the outer wall of the support foot 6, and the two sides of the outer wall of the lifting seat 8 extend into it; a battery box 17 is installed in the middle of the bottom of the drone body 1, and a power supply 18 is connected inside the battery box 17. An end cover 19 is connected to one side of the outer wall of the power supply 18, and a handle is installed in the middle of the outer wall of the end cover 19.

[0037] For specific implementation, please refer to Figures 1-4 First, the fan blades 3 on the outside of the drone frame 2 are activated. Then, the fan blades 3 rotate and drive the main body 1 of the drone to rise, allowing the drone to fly along a designated route. Through the drone's flight observation, potential hazards of water conservancy facilities such as dam development areas can be inspected. When the drone's battery power is low, the drone is controlled to land on the hangar platform of the drone nest. Then, the robotic arm of the drone nest grabs the end cover 19 and transfers the power supply 18 to the charging compartment for charging. After that, a new power supply 18 is grabbed from the fully charged compartment and transferred to the battery box 17, thereby achieving continuous flight by replacing the battery, allowing the drone to take off quickly and continue to perform inspection tasks.

[0038] The two sides of the outer wall of the fixing plate 4 are internally connected with threaded pins 5. The bottom of the drone body 1 is provided with threaded holes, and the threaded pins 5 extend into them. The fixing plate 4 and the support foot 6 form a "T" shaped structure.

[0039] See Figure 2 , Figure 4 and Figure 6Since the fixing plate 4 is connected to the support foot 6, first move the support foot 6 so that the top of the fixing plate 4 fits against the bottom of the drone body 1. Then rotate the threaded pin 5 to pass through the fixing plate 4 and connect it to the bottom of the drone body 1, thereby fixing the support foot 6. Afterwards, you only need to turn off the threaded pin 5 to complete the replacement of the support foot 6.

[0040] A slide block 13 is welded to the middle of the outer wall of the base 11. The base 11, the bottom plate 12 and the slide block 13 form a "U" shape. A fixed column 14 is slidably connected to the outer wall of the slide block 13. A groove corresponding to the base 11 is opened at the bottom of the outer wall of the fixed column 14. One side of the outer wall of the fixed column 14 is welded to the bottom of the support foot 6. The support foot 6 and the fixed column 14 form a "T" shape. A limit seat 16 is connected to the top of the outer wall of the slide block 13. The limit seat 16 has a "T" shape. The transmission plate 10, the fixed column 14 and the support foot 6 form a triangular stabilizing mechanism. A second spring 15 is fixedly connected to the middle of the outer wall of the slide block 13. A guide groove is opened at the top of the outer wall of the fixed column 14 and the limit seat 16 extends into it.

[0041] See Figures 5-9 When the drone needs to land on the ground during outdoor inspection, the electric push rod 7 is activated to retract and drive the lifting seat 8 to move downward. Since the two sides of the lifting seat 8 are rotatably connected to the transmission plate 10, the rotation of the lifting seat 8 will drive the transmission plate 10 to rotate, which will then generate a thrust on the base 11, causing the base 11 to drive the base plate 12 to move away from the support foot 6. The downward movement of the lifting seat 8 will stretch the first spring 9, causing it to deform. Then, the return of the first spring 9 will assist the lifting seat 8 to move upward.

[0042] See Figures 7-9 Because the base 11 is connected to the slide 13, the slide 13 slides along the fixed column 14, thereby guiding the base plate 12 to move in a straight line. At the same time, the limit seat 16 slides along the fixed column 14, thereby guiding the slide 13 to move in a straight line. This allows the base 11 to drive the base plate 12 to move smoothly to the designated position, reducing the error of the unfolding position and increasing the support area between the support foot 6 and the ground. At this time, the transmission plate 10, the fixed column 14 and the support foot 6 form a triangular stabilizing mechanism, thereby increasing the support area during landing, preventing the drone from sinking and tipping over, and reducing maintenance costs caused by tipping over.

[0043] When the drone performs a flight mission, the electric push rod 7 is activated to extend and move the lifting seat 8 upward, which in turn causes the base 11 to move the base plate 12 toward the support foot 6. At this time, the second spring 15 resets to assist the base 11 in returning to its original position, thereby reducing the space occupied by the landing support assembly and reducing the probability of the support assembly colliding during flight.

[0044] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
