Description

Technical Field

[0002] Drones are currently playing a significant role in the development of the low-altitude economy, and are widely used in reconnaissance, surveying, agriculture, inspection, and urban management. However, due to limitations in the current battery industry, drone flight time is typically around 30 minutes, requiring frequent recharging. Drone hangars, also known as drone airports or drone hangars, are ground infrastructure integrating advanced technologies. Through built-in flight paths, they enable drones to operate automatically, collect data, transmit data back, and analyze data, providing firsthand, accurate field data for subsequent on-site work, thus gaining widespread application. In the application of drone hangars, charging is the primary method of recharging drones. Currently, during recharging, only the drone's charging contacts connect to the hangar's charging contacts. During charging, installation and other environmental factors, such as hangar movement, can lead to poor contact at the charging contacts, affecting charging stability and even causing charging failures. Meanwhile, the drone generates a lot of heat during charging, which raises the battery temperature and significantly affects charging efficiency. When the battery temperature exceeds 45°C, abnormal situations such as the battery failing to charge or charging slowly will occur, limiting the drone's continuous operation time.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] Reference Figure 1-7This utility model provides a drone charging system, including a landing platform 1; a charging station on the landing platform 1; a charging pile 2 on the charging station; a charging device on the charging pile 2 that engages with the charging end of a drone 8; and a push rod assembly on the landing platform 1 for pushing the drone's charging end to engage with the charging device. When charging is required, the drone 8 lands on the landing platform 1. Based on the landing position, the push rod assembly is activated to align the drone 8 with the charging station, causing the drone 8's charging end to engage with the charging device on the charging pile 2 for charging. The positions of the charging stations on the landing platform 1 and the trajectory of the push rod assembly are designed according to actual conditions, allowing multiple charging stations to be set on the landing platform 1 to meet the charging needs of multiple drones 8.

[0028] In a detailed embodiment, the drone charging system further includes a drone tripod 3; the drone tripod 3 is provided with a charging protrusion 301; the charging protrusion 301 is provided with a charging contact 302; the charging device includes a charging slot that engages with the charging protrusion 301; the charging slot is provided with a charging spring pin that matches the charging contact 302. In use, as... Figure 7 As shown, the drone landing gear 3 is mounted onto the drone 8, and the charging contact 302 on the drone landing gear 3 is connected to the power supply of the drone 8. When charging is required, the drone 8 lands on the platform 1. Based on the landing position, the push rod assembly is activated to align the drone 8 with the charging station and advance it, so that the charging protrusion 301 on the drone landing gear 3 engages with the charging slot of the charging pile 2. At the same time, the charging contact 302 on the charging protrusion 301 contacts the charging pin in the charging slot to charge the drone 8.

[0029] In another feasible method, the aforementioned charging slot can be mounted on the drone tripod 3, and the charging protrusion 301 can be mounted on the charging station 2. In use, the drone tripod 3 is mounted on the drone 8, and the charging pins in the charging slot are connected to the power supply of the drone 8. The push rod assembly is activated, and the drone 8 is aligned with the charging station and pushed forward, causing the charging protrusion 301 on the charging station 2 to engage with the charging slot on the drone tripod 3 for charging.

[0030] The connection method between the charging device and the charging terminal of the drone can also be selected according to the actual situation, or other feasible connection structures can be selected.

[0031] Specifically, the push rod assembly includes a horizontal push rod 4 and a vertical push rod 5; the horizontal push rod 4 and the vertical push rod 5 are respectively movably connected to the platform surface of the take-off and landing platform 1, pushing the drone 8 back into position from two directions on the platform surface. The number of horizontal push rods 4 and vertical push rods 5 is designed as needed to ensure that after the drone 8 lands, it can be aligned with the charging station via the horizontal push rods 4 and the vertical push rods 5.

[0032] Furthermore, a push-pull element 6 is provided on the transverse push rod 4 or the longitudinal push rod 5; such as Figure 6 As shown, the push-pull component 6 includes a fixing part 601 and a gripper 602; the fixing part 601 is fixed to the horizontal push rod 4 or the vertical push rod 5; the gripper 602 is movably mounted on the fixing part 601. The actual installation position of the push-pull component 6 is determined according to the relative direction between the charging pile 2 and the landing point of the drone 8 in the charging station. When the charging pile 2 is located horizontally to the landing point, the push-pull component 6 is located on the horizontal push rod 4, such as... Figure 2-3 As shown, after the drone 8 lands in the parking area 101, the longitudinal push rod 5 is activated first to bring the drone 8 to a horizontal alignment with the charging station. Then, the transverse push rod 4 is activated to push the drone 8 laterally to the charging station, ensuring that the charging protrusion 301 is accurately inserted into the charging slot for charging. After charging is complete, the gripper 602 of the push-pull component 6 holds the drone 8, and the transverse push rod 4 is moved in the opposite direction, pulling the drone 8 out of the charging station to the parking area 101 via the gripper 602. The fully charged drone 8 then starts and leaves the take-off and landing platform 1. The number of push-pull components 6 on the push rod is determined by the number of charging stations; optionally, one push rod component is matched with one charging station.

[0033] Preferably, the fixing part 601 is provided with a slide rail 603 on the side facing the charging station; the gripper 602 is slidably mounted on the slide rail 603. The length direction of the slide rail 603 is the same as the length direction of the push rod where the fixing part 601 is located. By moving the gripper 602 on the slide rail 603, the clamping position can be adjusted to adapt to the size of the UAV 8 and ensure push-pull stability.

[0034] In a detailed embodiment, the push rod assembly further includes a lateral drive device and a longitudinal drive device; the output end of the lateral drive device is connected to the lateral push rod 4, and is used to drive the lateral push rod 4 to move laterally on the landing platform 1; the output end of the longitudinal drive device is connected to the longitudinal push rod 5, and is used to drive the longitudinal push rod 5 to move longitudinally on the landing platform 1. The lateral drive device and the longitudinal drive device are preferably drive motors, and their number is determined according to the number of lateral push rods 4 and longitudinal push rods 5, respectively. Preferably, each push rod is independently driven by a drive device, which facilitates pushing and pulling the UAV 8 back to its original position.

[0035] In one optimized embodiment, the charging station is equipped with two sets of charging piles 2, and the slots of the charging slots of the two sets of charging piles 2 are arranged opposite each other; the drone tripod 3 is equipped with two charging protrusions 301; the two charging protrusions 301 correspond one-to-one with the two charging slots. When the drone 8 is pushed to the charging station, the two charging protrusions 301 on the drone tripod 3 engage with the two charging slots respectively.

[0036] To improve the heat dissipation performance of the drone charging system, a heat dissipation device is installed in the charging station, preferably a cooling fan 7. The air vent of the cooling fan 7 faces the drone 8 to cool down the drone 8 during the charging process and ensure smooth charging.

[0037] In one embodiment, the present invention also provides a drone nest, including a nest body and the aforementioned drone charging system; the take-off and landing platform 1 is installed in the nest body.

[0038] Example 1:

[0039] like Figure 1-7 As shown, this embodiment provides a drone charging system, including a take-off and landing platform 1 and a drone landing gear 3.

[0040] The platform 1 is divided into an adjacent parking area 101 and a charging area 102. The charging area 102 is provided with three charging stations at equal intervals along the longitudinal direction. Each charging station is provided with two sets of charging piles 2, and the slots of the charging card slots of the two sets of charging piles 2 are arranged opposite each other. A cooling fan 7 is installed on the platform between the two sets of charging piles 2, and the air vents of the cooling fan 7 are arranged facing upwards.

[0041] The drone tripod 3 is provided with two charging protrusions 301 that match the charging slots; the charging protrusions 301 are provided with a metal charging area 102, and are provided with charging contacts 302 that match the charging spring pins; the two charging protrusions 301 correspond one-to-one with the two charging slots.

[0042] like Figure 5 As shown, the parking area 101 is equipped with two longitudinal push rods 5 and one transverse push rod 4; the two longitudinal push rods 5 are arranged in parallel, and the transverse push rod 4 is vertically positioned between the two longitudinal push rods 5, with the lengths of the push rods matching the length and width of the parking area 101. The four side plates of the lifting platform 1 are respectively provided with longitudinal and transverse sliding grooves. The left end of the longitudinal push rod 5 is slidably connected to the longitudinal sliding groove on the left side plate of the lifting platform 1, and the upper and lower ends of the transverse push rod 4 are slidably connected to the transverse sliding grooves on the upper and lower side plates of the lifting platform 1, respectively. Each push rod is independently driven by a drive motor, moving horizontally or longitudinally on the platform.

[0043] Three push-pull members 6 are spaced apart along the length of the transverse push rod 4, corresponding one-to-one with the three charging stations. Each push-pull member 6 includes a fixing part 601 and a gripper 602. The fixing part 601 is fixed to the transverse push rod 4, and a slide rail 603 is provided on the side of the fixing part 601 facing the charging station. The gripper 602 is slidably mounted on the slide rail 603.

[0044] When using, such as Figure 7As shown, the drone landing gear 3 is mounted onto the drone 8, and the charging contacts 302 on the drone landing gear 3 are connected to the power supply of the drone 8. When charging is required, the drone 8 lands in the parking area 101 of the take-off and landing platform 1, and matches the nearest charging station based on the landing position. The longitudinal push rod 5 is activated to bring the drone 8 longitudinally to a position horizontally aligned with the charging station. Then, the transverse push rod 4 is activated to push the drone 8 laterally to the charging station, so that the two charging protrusions 301 are inserted into the two charging slots respectively, and the charging contacts 302 on the charging protrusions 301 contact the charging pins in the charging slots to charge the drone 8. During the charging process, the cooling fan 7 located at the bottom of the drone 8 is turned on to cool the drone 8. After charging is completed, the gripper 602 of the push-pull member 6 clamps the drone landing gear 3, and the transverse push rod 4 is moved in the opposite direction, pulling the drone 8 out of the charging station to the parking area 101 through the gripper 602. The fully charged drone 8 then starts and leaves the take-off and landing platform 1.
