Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) battery swapping technology, and in particular to a battery box status isolation reading structure for an automated airport for battery swapping UAVs. Background Technology

[0002] Current automated battery-swapping drone airports typically integrate high-precision robotic arms with battery monitoring systems. The high-precision robotic arm performs battery placement and removal operations, ensuring accurate connection between the battery, drone, and battery compartment during the swapping process. The integrated battery monitoring system, located within the robotic arm or battery compartment, detects battery status through physical contact or wireless communication. This enables the automated battery airport to reliably determine whether the battery is charging, ensuring the drone can continuously and stably obtain power during inspections.

[0003] However, most existing battery testing systems on the market use external cameras to visually monitor the status lights in the battery compartment. The battery status (charging, fully charged, waiting to charge, charging failure) is represented by the different colors of each status light in the battery compartment. External camera visual monitoring is often subject to interference between the status lights in the battery compartment and interference from external ambient light, resulting in monitoring errors.

[0004] In view of this, the present invention provides a battery box status isolation reading structure for a battery-swapping unmanned aerial vehicle (UAV) automated airport. Utility Model Content

[0005] This utility model discloses an isolated reading structure for the battery box status of a battery-swapping drone automated airport, in order to solve the problem of how to read the charging status of the battery in the battery compartment of the drone automated airport without interference and with stable and accurate reading.

[0006] The technical solution of this utility model is as follows:

[0007] An isolated reading structure for the battery box status of a battery-swapping unmanned aerial vehicle (UAV) automated airport includes a battery box status light assembly. The battery box status light assembly has status lights and a reading device. The reading device includes a fixed frame, a light-blocking cotton, a reading circuit board, and a light-blocking cover arranged sequentially from back to front. The reading circuit board has a photodetector; each photodetector corresponds to one of the status lights. The light-blocking cotton has light-blocking holes, each corresponding to one of the status lights and one of the photodetectors. The fixed frame is black, and the light-blocking cover is fixedly connected to the battery box status light assembly.

[0008] According to a preferred embodiment of the present invention, the light-blocking cotton is provided with double-sided adhesive material on both the front and back sides, which is then bonded and fixed to the fixing frame and the reading circuit board, respectively.

[0009] According to a preferred embodiment of the present invention, a limiting rib is provided on the outer peripheral surface of the fixing frame, and buckles are provided oppositely on the inner walls of the upper and lower frame sides of the fixing frame. A protrusion is provided on the open end face of the fixing frame near the light-blocking cotton. The grooves on the upper and lower frame sides of the reading circuit board correspond to the buckles of the fixing frame. The reading circuit board is fixedly connected to the light-blocking cotton. The reading circuit board and the light-blocking cotton are located inside the fixing frame. The reading circuit board is located between the limiting rib and the buckle.

[0010] According to a preferred embodiment of the present invention, the light shield is provided with anti-detachment holes corresponding to the protrusions. The anti-detachment holes are fitted onto the protrusions of the fixing frame and fastened to serve as a top seal and anti-detachment fixation.

[0011] According to a preferred embodiment of the present invention, the isolated reading structure is installed on the drone battery box. The power supply line and 485 signal line of the reading circuit board are respectively connected to an independent power supply and a network video recorder (NVR). The independent power supply connected to the reading circuit board can effectively prevent the reading circuit board from affecting the accuracy of the judgment of the drone battery box itself. Each charging port on the drone battery box is equipped with a first charging board, and each compartment of the battery swapping compartment is equipped with a second charging board. The second charging board and the drone battery are charged through physical contact. The first charging board on the drone battery box is connected to the second charging board through a power extension line to extend the charging of the drone battery in the battery swapping compartment.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The light-shielding cotton of this invention is provided with light-shielding holes that correspond one-to-one with the status lights on the battery box. The fixing frame is set to black and equipped with a light-shielding cover, which realizes the partitioned closed identification of each status light of the battery box, so that it is not affected by adjacent influences or external environment. The wavelength and light intensity of the battery status lights are stably read by the circuit board photodetector, and the status of the battery box is accurately identified, avoiding the problem of incorrect battery status monitoring.
