Description

Technical Field

[0001] This utility model relates to the field of drone auxiliary equipment technology, and in particular to a drone charging base station. Background Technology

[0002] Drone charging stations are essential infrastructure for drones. The current status of drone charging stations is as follows:

[0003] Main Structure: The main body of a drone charging base station generally includes a fixed equipment frame, which includes battery storage, transportation, and charging facilities. The main design of the charging base station is usually based on a planar layout, and the battery installation and charging process requires manual intervention.

[0004] Charging interface: Traditional charging stations are usually equipped with fixed charging interfaces, which need to be manually connected to the drone battery. During each charging process, staff need to adjust the position of the charging interface to ensure precise alignment between the battery and the charging equipment;

[0005] Battery replacement: In current technology, drone batteries are typically removed and replaced manually. This process relies on manual operation by staff to remove the battery from the drone and place it on a charging device. The battery replacement process can be inefficient and carries the risk of battery misalignment.

[0006] Battery charging: Traditional charging methods typically use fixed contact points on the battery, connecting it to the charging interface. The charging process is usually unilateral, requiring manual operation to connect the battery and manual monitoring of the charging status, lacking intelligent battery management and automated control.

[0007] Spatial Layout: Traditional charging base stations typically use a planar layout, requiring a large space for storing batteries and charging equipment. Due to the lack of utilization of vertical space, the space utilization efficiency of the equipment is low.

[0008] Safety Mechanisms: Existing drone charging stations lack effective electromagnetic shielding and emergency protection measures during battery replacement, thus posing certain safety hazards during battery replacement or charging.

[0009] In summary, existing technologies suffer from at least the following bottlenecks: They rely heavily on manual intervention, requiring manual operation for battery installation and removal, which is not only inefficient but also carries the risk of misalignment; charging efficiency is limited, as fixed charging interfaces require manual adjustment, affecting docking accuracy; battery management is rudimentary, lacking an intelligent scheduling system and the ability to monitor charging and discharging status in real time; space utilization is insufficient, with planar layouts leading to significant waste of three-dimensional space; and safety mechanisms are lacking, with the battery replacement process lacking electromagnetic shielding and emergency protection. These technical deficiencies result in traditional base stations being complex to operate, inefficient, and fraught with safety hazards, making it difficult to meet the operational and maintenance needs of large-scale drone swarm operations.

[0036] The present invention will be further described below with reference to the embodiments.

[0037] Example:

[0038] See Figure 1-9 A drone charging base station includes a main body 10. A clamping assembly 2 and a charging assembly 3 are installed inside the main body 10. The clamping assembly 2 is used for clamping and conveying the battery, and the charging assembly 3 is used for charging the battery. The clamping assembly 2 is located on one side of the charging assembly 3. A conversion assembly 1 is installed on one side of the main body 10 for conveying the battery via a rotating ring. An external cable 101 is installed on one side of the main body 10.

[0039] The conversion component 1 includes a conversion frame 11, which is fixedly connected to one side of the main body 10. Parking racks 111 are provided on both sides of the conversion frame 11. A linear moving frame 123 and a limiting sliding frame 124 are slidably assembled inside the conversion frame 11. An upper and lower sliding frame 125 is slidably assembled inside the limiting sliding frame 124. A lifting cylinder 1253 is installed inside both the linear moving frame 123 and the upper and lower sliding frame 125. A lifting shaft 1254 is installed at the output end of the lifting cylinder 1253. A placement frame 1255 is fixedly connected to the top of the lifting shaft 1254. A first sensor 1256 is installed on the top of the placement frame 1255.

[0040] Four symmetrically arranged first lead screw motors 12 are installed on one side of the conversion frame 11. Each first lead screw motor 12 has a first transmission lead screw 121 installed at its output end. The limiting transmission frame 122 and the linear movement frame 123 are respectively sleeved on the outer circumferential surface of the two first transmission lead screws 121. The limiting slide frame 124 and the upper and lower slide frames 125 are connected by a spring 1252. A damper is provided on the spring 1252.

[0041] A limiting transmission frame 122 is fixedly connected to the inner wall of the conversion frame 11, and a limiting straight shaft 1251 is fixedly connected to both sides of the upper and lower sliding frame 125. The limiting straight shaft 1251 is slidably assembled inside the limiting transmission frame 122.

[0042] The clamping assembly 2 includes a second lead screw motor 21, which is mounted on the inner wall of the main body 10. A second transmission lead screw 211 is mounted on the output end of the second lead screw motor 21. An axial limiting block 212 is sleeved on the outer circumferential surface of the second transmission lead screw 211. A sliding cylinder 213 is fixedly connected to the bottom of the axial limiting block 212. A sliding frame 214 is mounted on the bottom of the sliding cylinder 213. Two symmetrically arranged second sensors 215 are mounted on the bottom of the sliding frame 214. Four symmetrically arranged limiting sliders 223 are slidably assembled inside the sliding frame 214. A clamping plate 224 is fixedly connected to the bottom of the limiting sliders 223.

[0043] A servo motor 22 is installed inside the sliding frame 214. A disk 221 is installed at the output end of the servo motor 22. A hinge rod 222 is hinged to the disk 221 and the limit slider 223.

[0044] The charging component 3 includes a conveyor motor 31, which is installed inside the main body 10. Four symmetrically arranged conveyor shafts 311 are rotatably installed inside the main body 10. One of the conveyor shafts 311 is installed at the output end of the conveyor motor 31. A rotating wheel 312 is fixedly connected to the top of the conveyor shaft 311. A conveyor belt 32 is sleeved on the four rotating wheels 312. Several equidistantly distributed conveyor frames 321 are fixedly connected to the top of the conveyor belt 32. Two symmetrically arranged pressing cylinders 33 are installed on the top of the main body 10. Several equidistantly distributed charging top plates 331 are installed at the bottom of the pressing cylinders 33.

[0045] The specific implementation process of this utility model is as follows: When the device is in use, the drone is placed on the parking rack 111 on the conversion frame 11 on one side of the main body 10. At this time, the placement frame 1255 is located at the bottom of the drone. The first sensor 1256 of the cylinder senses the drone's position with the sensor on the drone. After sensing, the drone's position is confirmed. At this time, the drone turns off its electromagnet. The battery module is equipped with a strong magnet corresponding to the electromagnet. After the battery module is removed, the four first lead screw motors 12 on the conversion frame 11 are turned on simultaneously. The turning on of the first lead screw motors 12 causes the four first transmission lead screws 121 (the first transmission lead screws 121 are reciprocating lead screws) to rotate synchronously. The synchronous rotation of the first transmission lead screws 121 causes the linear moving frame 123 and the limiting slide frame 124 to slide to their relative positions. When the limiting slide frame 124 moves to the concave position of the limiting transmission frame 122, because the limiting linear... The limiting sliding of shaft 1251 and limiting slide frame 124 causes the upper and lower slide frames 125 to be pulled down. At this time, the linear moving frame 123 moves alternately from the top of the upper and lower slide frames 125. At this time, the fully charged battery module in the linear moving frame 123 and the replacement battery module in the limiting slide frame 124 are exchanged. After the exchange is completed, the first sensor 1256 on the placement frame 1255 in the linear moving frame 123 senses the drone and confirms the drone's position. After the position is confirmed, the lifting cylinder 1253 and the electromagnet inside the drone (the drone is equipped with a backup battery module, and the main battery module charges the backup battery module) are activated. The lifting cylinder 1253 lifts the lifting shaft 1254, so that the battery module in the placement frame 1255 contacts the installation position of the drone, so that the strong magnet on it is strongly connected to the electromagnet, so that the installation and replacement of the battery module can be completed quickly.

[0046] When the battery module needs to be placed or retracted, the second lead screw motor 21 inside the clamping assembly 2 is activated, causing the second transmission lead screw 211 to rotate, which in turn causes the axial limiting block 212 to move to the top of the battery module. At this time, the second sensor 215 senses the position of the battery module. After sensing the battery module, the sliding cylinder 213 is activated, causing the sliding frame 214 to slide. After the sliding frame reaches the top of the battery module, the servo motor 22 is activated, causing the disc 221 to rotate. The rotation of the disc 221 causes the limiting slider 223 to slide towards the center of the disc 221 through the sliding of the hinge rod 222, thereby causing the clamping plate 224 to clamp the lithium battery module. After clamping is completed, the battery is placed and retracted by repeating the above steps.

[0047] During the clamping process, the clamping assembly 2 records the quantity through the sensing of the second sensor 215, places the clamped battery module to be charged inside the conveyor frame 321, and then turns on the conveyor motor 31, causing the conveyor shaft 311 to rotate, which in turn causes the rotating wheel 312 to rotate. The rotation of this rotating wheel 312 drives the other rotating wheels 312 for auxiliary transmission through the setting of the conveyor belt 32, and conveys the lithium battery module to be charged to the bottom of the charging top plate 331. Then, the pressing cylinder 33 is turned on to press the charging top plate 331 down to the top of the lithium battery module for charging, thereby improving the functionality of the equipment.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
