Description

Technical Field

[0001] This utility model relates to the technical field of drone docking and charging devices, and specifically to an intelligent identification drone docking and charging device. Background Technology

[0002] Drone docking and charging devices are equipment or systems that provide docking and charging functions for drones. They are an important guarantee for the automated operation of drones. In order to ensure flight capabilities, drones cannot carry batteries that are too heavy, so drone operations need to be supported by drone docking and charging devices.

[0003] According to the public announcement (CN218258773U), a rechargeable take-off and landing platform device for unmanned aerial vehicles (UAVs) is disclosed. This technology discloses a technical solution that includes "a main board, a top plate directly above the main board, an airbag located between the top plate and the main board, the airbag being located at the center between the main board and the top plate, and an auxiliary mechanism on the side of the airbag. The auxiliary mechanism includes a sleeve, which is fixedly installed on the top of the main board. A movable rod is movably connected to the center of the top of the sleeve. The bottom of the movable rod is fixedly connected to the bottom of the top plate. A first magnetic plate is fixedly connected to the center of the bottom of the movable rod. The first magnetic plate is located inside the sleeve. A second magnetic plate is located directly below the first magnetic plate. The second magnetic plate is located inside the bottom of the sleeve and is fixedly installed on the top of the main board. This technical solution has the technical effect that the main board can provide main support for the structure on it, while the top plate can serve as a take-off and landing platform for the UAV."

[0004] However, when a drone is charging, its interface is relatively fragile and is easily compressed by external forces, which can cause excessive local pressure and damage the interface and cables. In contrast, the method of fixing the drone with magnetic sheets mentioned above is still easy to cause the drone to shake and be damaged when subjected to strong forces.

[0005] To address the aforementioned issues, this application proposes an intelligent identification-based drone docking and charging device. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing an intelligent identification drone docking and charging device.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A smart identification drone docking and charging device includes a base frame, a landing platform fixedly connected to the upper part of the base frame, a landing gear slidably connected to the upper part of the landing platform, a pressure sensor provided on the upper part of the landing platform, a motor fixedly connected inside the landing platform, a transmission mechanism provided inside the landing platform, a positioning mechanism provided inside the landing platform, a flexible clamping mechanism provided on the upper part of the positioning mechanism, a battery storage compartment fixedly connected to the lower part of the landing platform, and a charging cable provided at the output end of the battery storage compartment.

[0008] A flexible clamp is fixedly connected to the lower part of the landing platform. The surface of the flexible clamp is slidably connected to the charging cable. This design allows the charging cable to be fixed to the lower part of the landing platform by the flexible clamp when not in use, thereby preventing the charging cable from leaking electricity due to dragging and contacting other objects.

[0009] The transmission mechanism includes a main shaft fixedly connected to the output end of the motor. A driving bevel gear is fixedly connected to the surface of the main shaft. A driven bevel gear is rotatably connected inside the base frame. The surface of the driven bevel gear meshes with the driving bevel gear. A secondary shaft is fixedly connected to the side end of the driven bevel gear. A slot is provided on the surface of the secondary shaft. This configuration allows the motor to drive the two secondary shafts to rotate.

[0010] The positioning mechanism includes a double-helix rotating sleeve slidably connected to the surface of the secondary rotating shaft. A retaining strip is fixedly connected inside the double-helix rotating sleeve. The retaining strip is slidably connected to the secondary rotating shaft through a retaining groove. A slide is slidably connected inside the landing platform. The inner wall of the slide is threadedly connected to the double-helix rotating sleeve. A clamping platform is fixedly connected to the upper part of the slide. The secondary rotating shaft can drive the clamping platform to move inward to fix the landing gear.

[0011] The flexible clamping mechanism includes a clamping plate disposed on the side end of the clamping platform. A guide rod is fixedly connected to the side end of the clamping plate. The surface of the guide rod is slidably connected to the clamping platform. A spring is fixedly connected to the side end of the clamping plate. The fixed end of the spring is fixedly connected to the clamping platform. A buffer pad is fixedly connected to the side end of the clamping plate. By setting up the flexible clamping mechanism, the applicability of the positioning mechanism is enhanced, and more types of UAVs with landing gear can be positioned.

[0012] The beneficial effects of this utility model are: after the landing gear contacts the pressure sensor, the pressure sensor starts the motor according to the detected pressure data, and uses the transmission mechanism to drive the positioning mechanism to fix the landing gear. The drone is charged through the battery compartment and charging cable, which avoids the damage to the interface and cable caused by excessive local pressure at the charging interface due to external force when the drone is charging.

[0013] The flexible clamping mechanism enhances the applicability of the positioning mechanism, enabling it to position drones with landing gear of various specifications. The buffer pads also prevent damage to the landing gear surface during positioning. Attached Figure Description

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0026] Refer to the image - Figure 4 A smart identification drone docking and charging device includes a base frame 1, a landing platform 2 fixedly connected to the upper part of the base frame 1, a landing gear 3 slidably connected to the upper part of the landing platform 2, and two pressure sensors 4 installed on the upper part of the landing platform 2 to identify whether the drone has landed. A motor 5 is fixedly connected inside the landing platform 2, a transmission mechanism 6 is installed inside the landing platform 2, and a positioning mechanism 7 is installed inside the landing platform 2. A flexible clamping mechanism 8 is installed above the positioning mechanism 7. A battery compartment 9 is fixedly connected to the lower part of the landing platform 2, and a charging cable 10 is installed at the output end of the battery compartment 9. When the drone lands on the landing platform 2, the landing gear 3 contacts the pressure sensor 4, and the pressure sensor 4 senses and starts the motor 5. The transmission mechanism 6 drives the positioning mechanism 7 to fix the landing gear 3, and the drone is charged through the battery compartment 9 and the charging cable 10. This avoids the drone being damaged due to excessive local pressure at the charging interface caused by external force during charging.

[0027] Refer to the image - Figure 2 A flexible clamp 11 is fixedly connected to the lower part of the landing platform 2. Multiple flexible clamps 11 are provided. The surface of the flexible clamp 11 is slidably connected to the charging cable 10. When the charging cable 10 is aligned with the flexible clamp 11 and pressed, the flexible clamp 11 deforms and returns to its original shape after the charging cable 10 enters. This allows the charging cable 10 to be fixed to the lower part of the landing platform 2 by the flexible clamp 11 when it is not in use, thereby preventing the charging cable 10 from leaking electricity due to dragging and contacting other objects.

[0028] Refer to the image - Figure 4The transmission mechanism 6 includes a main shaft 601 fixedly connected to the output end of the motor 5. A driving bevel gear 602 is fixedly connected to the surface of the main shaft 601. Two driving bevel gears 602 are provided. A driven bevel gear 603 is rotatably connected inside the base frame 1. Two driven bevel gears 603 are provided. The inner circumference of the base frame 1 at this location is equal to the outer circumference of the driving bevel gear 602 at this location. The surface of the driven bevel gear 603 meshes with the driving bevel gear 602. The driven bevel gear 603 and the driving bevel gear 602 are compatible. A secondary shaft 604 is fixedly connected to the side end of the driven bevel gear 603. Two secondary shafts 604 are provided. A slot 605 is opened on the surface of each secondary shaft 604. The motor 5 drives the main shaft 601 to rotate, thereby driving the driven bevel gear 603 to rotate through the driving bevel gear 602, causing the secondary shafts 604 to rotate accordingly. This allows the motor 5 to drive both secondary shafts 604 to rotate.

[0029] Reference Figure 1 - Figure 4 The positioning mechanism 7 includes a double-helix sleeve 701 slidably connected to the surface of the secondary rotating shaft 604. Two double-helix sleeves 701 are provided on one secondary rotating shaft 604. A retaining strip 702 is fixedly connected inside the double-helix sleeve 701. Two retaining strips 702 are provided inside the double-helix sleeve 701. The retaining strips 702 are slidably connected to the secondary rotating shaft 604 through a retaining groove 605. The retaining strips 702 and the retaining groove 605 are adapted to each other. A slide 703 is slidably connected inside the landing platform 2. The inner wall of the slide 703 is threadedly connected to the double-helix sleeve 701. The slide 703 and the double-helix sleeve The upper part of the slide 703 is fixedly connected to the clamp 704. The secondary rotating shaft 604 drives the clamp 702 on the double helix rotating sleeve 701 to rotate synchronously through the slot 605 and the clamp 702 on the double helix rotating sleeve 701. This causes the slide 703 on the surface of the double helix rotating sleeve 701 to drive the clamp 704 to move inward and fix the landing gear 3. Since the double helix rotating sleeve 701 and the secondary rotating shaft 604 are slidably connected, the double helix rotating sleeve 701 can change its position according to different sizes of landing gear 3 while rotating, thus having stronger adaptability and being able to fix different specifications of UAV landing gear 3.

[0030] Reference Figure 1 - Figure 4The flexible clamping mechanism 8 includes a clamping plate 801 disposed on the side end of a clamping platform 704. A guide rod 802 is fixedly connected to the side end of the clamping plate 801. The surface of the guide rod 802 is slidably connected to the clamping platform 704. The outer circumference of the guide rod 802 is equal to the inner circumference of the clamping platform 704. One clamping platform 704 corresponds to two guide rods 802, thereby ensuring the force balance of the clamping plate 801 during movement. A spring 803 is fixedly connected to the side end of the clamping plate 801. The spring 803 is paired with the guide rod 802 one-to-one. The fixed end of the spring 803 is fixedly connected to the clamping platform 704, and the side end of the clamping plate 801 is fixedly connected to the buffer pad 804. The buffer pad 804 prevents damage to the surface of the landing gear 3 when positioning it. When one side clamping plate 801 contacts the landing gear 3 while the corresponding other side clamping plate 801 does not contact it, the spring 803 can be squeezed to buffer the impact, thus enhancing the applicability of the positioning mechanism 7 and enabling it to position more UAVs with landing gear 3 of different sizes and positions.

[0031] Working principle:

[0032] This intelligent drone docking and charging device works as follows: when the landing gear 3 contacts the pressure sensor 4, the pressure sensor 4 senses and starts the motor 5. The motor 5 drives the main shaft 601 to rotate, which in turn drives the driven bevel gear 603 to rotate through the active bevel gear 602, causing the secondary shaft 604 to rotate as well. This allows the motor 5 to drive both secondary shafts 604 to rotate. The secondary shafts 604 rotate synchronously through the slot 605 and the retaining strip 702 on the double helix sleeve 701, causing the retaining strip 702 to rotate synchronously. This causes the slide 703 on the surface of the double helix sleeve 701 to move the clamping platform 704 inward to fix the landing gear 3. Because the double helix sleeve 701 and the secondary shafts 604 are slidably connected, the double helix sleeve 701 can change its position according to different sizes of landing gear 3 while rotating, thus having stronger adaptability and being able to fix landing gear 3 of different specifications of drones.

[0033] The intelligent identification drone docking and charging device can buffer the landing gear 3 when one side clamp 801 contacts the landing gear 3 while the corresponding other side clamp 801 does not. This strengthens the applicability of the positioning mechanism 7, allowing it to position drones with landing gear 3 of different sizes and positions. The buffer pad 804 also helps to prevent damage to the surface of the landing gear 3 during positioning.
