Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a fully automatic battery replacement airport for unmanned aerial vehicles. Background Art

[0002] As the recognition of the application value of drones deepens, drones are developing rapidly in the consumer, industrial and military markets. Drones are increasingly being used in many fields.

[0003] However, the flight time of drones has become the biggest bottleneck hindering the development of drones. Although lithium-ion batteries are the batteries with the best overall performance on the market, they still cannot fully meet the drone's flight time requirements. Therefore, the drone charging issue must be considered during the use of drones.

[0004] At present, the battery replacement of drones has the following disadvantages: drones need to be frequently charged and replaced. According to the traditional method, manual battery replacement by staff requires huge manpower investment and requires personnel on duty, which makes it impossible to work in the field for a long time. In addition, the batteries of existing drone airports are all placed in a separate charging slot for charging. When the drone needs to return to change the battery, after the drone lands on the take-off and landing platform of the drone airport, the entire take-off and landing platform drives the drone to land inside the drone airport for automatic battery replacement operation, resulting in the size of the drone airport to be very large, requiring space to accommodate the take-off and landing platform, increasing the overall size and weight of the fully automatic drone cabin, and increasing the cost. After the entire take-off and landing platform drives the drone to land, the mechanical arm works to clamp the battery and put it into the charging slot, and then clamps the fully charged battery back into the drone. The mechanical arm is used to clamp and store the battery, and the control of the mechanical arm operation program and operation trajectory is very complicated, making the drone airport large in size and very expensive. Furthermore, due to the certain position error after the drone lands, the mechanical arm cannot accurately clamp the battery, which also brings difficulties to the automatic battery replacement of the drone, and complex procedures are required to land the drone at a precise position.

[0041] like Figures 1 to 9As shown, an embodiment of the present invention provides a fully automatic battery replacement airport for unmanned aerial vehicles, including a cabin and a movable cabin door (not shown in the figure), wherein a unmanned aerial vehicle positioning mechanism, a lifting mechanism 50, a charging and replacing mechanism 60 and a bracket 100 are arranged in the cabin, wherein the unmanned aerial vehicle positioning mechanism is used to clamp the base of the unmanned aerial vehicle 10 after landing, and comprises a longitudinal clamping mechanism 20, a transverse clamping mechanism 30 and a take-off and landing platform 40, wherein the take-off and landing platform 40 is fixed in the cabin by a bracket 100, wherein a through hole 41 is arranged at the center of the take-off and landing platform 40, wherein the longitudinal clamping mechanism 20 is located in the through hole 41 and is used to longitudinally clamp and release the base of the unmanned aerial vehicle, and is driven to move up and down through the through hole by the lifting mechanism 50; wherein the transverse clamping mechanism 30 is placed on the upper surface of the take-off and landing platform 40, and is used to clamp and release the base of the unmanned aerial vehicle by transverse reciprocating motion; wherein the lifting mechanism 50 is placed below the longitudinal clamping mechanism 20 and is used to drive the longitudinal clamping mechanism to move up and down, wherein the charging and replacing mechanism 60 is placed below the longitudinal clamping mechanism 20 and is perpendicular to the longitudinal clamping mechanism 20, and is used to charge and replace the battery of the unmanned aerial vehicle. The structure is simple and compact. It does not require the entire take-off and landing platform to move and the mechanical arm to clamp and remove the battery. The logic control is simple and the cost is low.

[0042] Furthermore, the longitudinal clamping mechanism includes two symmetrically arranged clamping parts 21, two first sliders 24, two screw rods 23, and two first motors 22. The two first motors 22 respectively drive the two screw rods 23 to move. The two screw rods are respectively provided with two first sliders 24. The two first sliders respectively drive the two clamping parts 21 to move to clamp or loosen the UAV base; a slide groove 33 is provided on the take-off and landing platform 40, and the transverse clamping mechanism 30 includes two symmetrically arranged cross bars 31 and four second sliders 32. The four second sliders are respectively connected to the four ends of the two cross bars and move in the slide groove 33, so that the UAV is pushed to move back to the center after landing on the take-off and landing platform.

[0043] Furthermore, the clamping portion 21 is wedge-shaped, and a V-shaped groove 12 is provided on the upper base of the drone. When the drone needs to be fixed, the clamping portion 21 is driven by the first motor to move into the V-shaped groove to clamp the drone 10.

[0044] Furthermore, the lifting mechanism 50 includes a lifting rod 51 , and the lifting rod 51 moves under the push of the lifting mechanism motor 52 , so that the longitudinal clamping mechanism 20 moves upward and downward.

[0045] Further, the charging and swapping mechanism 60 includes a battery module 11, a battery module fixing part and a battery slide assembly. The battery module 11 includes a battery box and a battery placed in the battery box and electrically connected. The battery box is provided with a clamping part 111. The battery module fixing part includes a bottom plate 63. The bottom plate is provided with a clamping part 631. The clamping part 631 is adapted in shape to the clamping part 111 on the battery box. The lower surface of the bottom plate 63 is provided with a driving mechanism to drive the battery module fixing part to move back and forth horizontally. The battery slide assembly includes a slide rail bracket bottom plate 64. The two ends of the slide rail bracket bottom plate are respectively provided with slide rail bracket end plates. The slide rail bracket end plates are extended toward the slide rail bracket bottom plate and provided with conductive slide rails 61. The battery module 11 moves along the conductive slide rail 61 driven by the battery module fixing part. The battery module moves along the conductive slide rail driven by the battery module fixing part. By symmetrically providing snap-on parts on opposite sides of the battery box, clamping parts are vertically symmetrically provided around the bottom plate of the battery module fixing part. The battery module is placed in the battery slot of the drone. When the battery needs to be replaced, the drone moves downward with the battery module, and the snap-on part on the bottom plate of the battery module fixing part is inserted into the clamping part of the battery module. The battery slide assembly slides to the right by the distance of a battery module, and the fully charged battery module is driven into the battery slot of the drone. The battery module in the drone that needs to be charged moves to the right synchronously. The drone moves upward to the take-off and landing platform to perform the flight mission, completing a battery replacement operation step. The structure is simple, low cost, and has low requirements on the accuracy of the battery position after the drone lands. There is no need for a mechanical arm to clamp the battery. The control logic is simple and stable. At the same time, it also reduces the size of the drone airport and facilitates transportation.

[0046] Furthermore, the other two opposite sides of the battery box are provided with electrode sheets 112, and the conductive rails 31 slide in cooperation with the electrode sheets 112 to charge the battery through the electrode sheets 112. The battery module is temporarily stored in the middle of the conductive rails, which play the role of both guide and charging electrode.

[0047] Furthermore, the number of the battery modules 11 is two or more, and the two or more battery modules 11 are sequentially adapted and connected end to end through the connecting parts 111. Preferably, four battery modules are replaced and used repeatedly in turn, and the replacement of four battery modules constitutes one cycle.

[0048] Furthermore, the driving mechanism includes a second motor and a motor shaft. The second motor drives the motor shaft to move forward and reversely, and the motor shaft drives the battery module 11 fixing part to move back and forth horizontally through the bottom plate 63. The motor drives the battery module fixing part to move back and forth horizontally through the forward and reverse rotation of the motor. When the drone battery is out of power, it returns to land on the take-off and landing platform, stops and descends, and the driving mechanism drives the battery module fixing part to move, and the battery module moves to the drone battery slot. The used battery moves to the conductive slide rail under the push of the driving mechanism. The structure is compact and can be charged and recycled.

[0049] Furthermore, a slide rail bracket 62 is further provided on the bottom plate of the slide rail bracket, and the conductive slide rail is fixed in the slide rail bracket. The conductive slide rail can be further stabilized by providing the slide rail bracket to prevent the battery module from shaking when moving on the conductive slide rail.

[0050] Furthermore, the number of the conductive rails 61 is eight, and the space enclosed by every four conductive rails is adapted to the shape of the battery box, so that the battery module can move left and right stably.

[0051] Specifically, in this embodiment, one battery module is preferably installed in the battery slot at the bottom of the drone, and other battery modules are stored inside the drone airport for fully automatic battery replacement. Multiple spare battery modules are stored in the drone airport, preferably three battery modules. When the drone is short of power during flight, the drone alarms when the power is low, and it needs to return to the drone airport for battery replacement. The drone will automatically return and land on the take-off and landing platform of the drone airport. Due to the accuracy of the landing point, the position of the drone needs to be adjusted. At this time, the transverse clamping mechanism works, and the drone is driven by the crossbar of the transverse clamping mechanism to move toward the transverse center of the take-off and landing platform. When the drone reaches the transverse center of the take-off and landing platform, the longitudinal clamping mechanism starts to work. Under the action of the first motor, the screw rod rotates, and the first slider placed on the screw rod moves, driving the clamping head to move. The clamping head clamps the drone to move, so that the drone moves to the longitudinal center position of the take-off and landing platform. At this point, the drone completes the position return and is located in the through hole. Then, the longitudinal clamping mechanism clamps the drone base and performs a battery replacement operation when it drops to the set position under the action of the lifting mechanism. At this time, the charging and battery replacement mechanism starts to work. The clamping part on the battery module fixture is inserted into the clamping part of the battery module. When the drone is lowered into place, the battery module fixture is shifted to the right by one battery module position under the drive of the driving mechanism. At this time, the fully charged battery module is inserted into the battery slot of the drone. The drone rises to the landing platform under the action of the lifting mechanism, takes off and continues to complete the flight mission. At this point, the battery replacement process is completed, and it goes back and forth. After replacing the battery, the drone continues to perform the corresponding task, and the replaced battery is charged in the drone airport and can be used repeatedly. The steps for replacing the battery module are repeated as above, and will not be repeated here one by one.

[0052] The invention has a simple structure and low cost. The longitudinal clamping mechanism clamps the drone to move in the through hole without the need for the entire take-off and landing platform to move up and down, saving space and thus reducing the size and weight of the drone airport. It saves costs, is convenient for transportation, has a simple structure, and is convenient for automated operation. It can be realized through simple control logic, without the need for a mechanical arm to clamp or remove the battery. And the accuracy of the landing position of the drone is low. At the same time, the cost of the drone airport is also reduced.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
