[0036] As described in the background section, most vehicle-mounted drones currently operate by launching the drones from a stationary vehicle, and the drones cannot be charged on the helipad. During vehicle movement, the drones exhibit poor stability and swaying. The technical problem this disclosure aims to solve is to overcome the limitations of existing vehicles in providing a helipad for self-charging of drones, improve the stability of the drones in a stationary state, and enable drone launch while the vehicle is in motion.
[0037] 1. Currently, vehicle-mounted drones cannot be launched while the vehicle is in motion;
[0038] 2. The drone hangar lacks portable charging devices, which cannot guarantee the drone's flight endurance.
[0039] The technical problem to be solved by the present invention is to overcome the shortcomings of related technologies and to provide a vehicle-mounted drone electromagnetic attraction wireless charging structure that enables drones to be stably launched and wirelessly charged while the vehicle is in motion.
[0040] The technical solution adopted in this disclosure is as follows: Currently, most vehicle-mounted drones are launched when the vehicle is stationary, and the drones cannot be charged on the helipad. During vehicle movement, the drone's stability is poor, resulting in swaying. The technical problem this disclosure aims to solve is to overcome the limitation that existing vehicles cannot provide a helipad for self-charging of vehicle-mounted drones, improve the stability of the drone in its stationary state, and enable drone launch while the vehicle is in motion.
[0041] This disclosure provides an electromagnetic attraction and charging device for a vehicle-mounted drone, including an attraction mechanism for attracting the drone, a lifting mechanism for controlling the raising and lowering of the attraction mechanism, and a wireless charging module disposed on the attraction mechanism, wherein the wireless charging module is used to charge the drone.
[0042] The adsorption mechanism includes a movable sleeve 3 and an electromagnet 2 disposed on the movable sleeve 3. The movable sleeve 3 is connected to the lifting mechanism.
[0043] The wireless charging module is integrated with the electromagnet 2.
[0044] The vehicle-mounted drone electromagnetic attraction and charging device also includes an elastic element 6 for applying an elastic force to the movable sleeve 3.
[0045] The lifting mechanism includes a drive motor and a transmission mechanism connected to the drive motor. The transmission mechanism is a lead screw and nut mechanism, with the output end of the drive motor fixedly connected to the lead screw of the transmission mechanism, and the nut of the transmission mechanism connected to the fixed sleeve 4. The lead screw and nut form a helical transmission.
[0046] The transmission mechanism is a lead screw and nut mechanism.
[0047] The vehicle-mounted drone electromagnetic attraction and charging device further includes a fixed sleeve 4 for guiding the movable sleeve 3, the fixed sleeve 4 being sleeved on the movable sleeve 3.
[0048] The vehicle-mounted drone electromagnetic attraction and charging device also includes a support sleeve 5, and the fixed sleeve 4 is disposed on the support sleeve 5.
[0049] Example
[0050] Specifically, as shown in Figures 1 to 4, this embodiment provides an electromagnetic attraction and charging device for a vehicle-mounted drone, including an attraction mechanism for attracting the drone, a lifting mechanism for controlling the raising and lowering of the attraction mechanism, and a wireless charging module disposed on the attraction mechanism. The wireless charging module is used to charge the drone.
[0051] As shown in Figures 1 and 2, the adsorption mechanism includes a movable sleeve 3 and an electromagnet 2 mounted on the movable sleeve 3. The movable sleeve 3 is connected to the lifting mechanism. The electromagnet 2 is a de-energized electromagnet. The wireless charging module is integrated with the electromagnet 2. When the electromagnet 2 attracts the drone body, the wireless charging module can charge the drone.
[0052] In this way, when it is necessary to charge the drone parked on the helipad, the lifting mechanism can be used to control the movable sleeve 3 to move upward, thereby driving the electromagnet 2 and the wireless charging module to move upward and extend out of the helipad, so that the electromagnet 2 can attract the drone and the wireless charging module can be electrically connected to the drone for charging.
[0053] When the drone does not need to be charged, the lifting mechanism can control the movable sleeve 3 to descend, thereby causing the electromagnet 2 and the wireless charging module to descend, so as to avoid the electromagnet 2 and the wireless charging module protruding from the landing pad from obstructing the take-off or landing of the drone.
[0054] Furthermore, since electromagnet 2 is a de-energized electromagnet, it remains magnetic when not energized, thus attracting and securing the drone. When the drone needs to take off, electromagnet 2 can be briefly energized, demagnetizing it and allowing the drone to take off. In this way, electromagnet 2 does not need to be constantly energized; it only needs to be briefly energized when the drone needs to take off, effectively saving power.
[0055] As shown in Figures 2 and 3, the vehicle-mounted drone electromagnetic attraction and charging device of this embodiment further includes an elastic element 6 for applying an elastic force to the movable sleeve 3. The electromagnet 2 is engaged inside the movable sleeve 3, and the elastic element 6 is located below the movable sleeve 3. The elastic element 6 is a cylindrical helical spring and a compression spring, and applies an upward elastic force to the movable sleeve 3. The attraction mechanism is in a floating state, ensuring that the electromagnet 2 can move up and down to absorb the gap tolerance of the drone landing on the landing pad, ensuring that the electromagnet 2 can stably attract the drone.
[0056] As shown in Figures 1 to 3, the movable sleeve 3 is installed in the middle of the helipad. A lifting mechanism enables the movable sleeve 3 and the electromagnet 2 to be raised and lowered. The adsorption mechanism can lower the sleeve to a position where the electromagnet 2 is flush with the helipad, ensuring that the clamping arm of the clamping mechanism on the helipad is unobstructed when clamping the drone. The helipad is mounted on the vehicle body. A drone bay accommodating the helipad and the drone is located on the vehicle body. The helipad can be raised and lowered.
[0057] As shown in Figures 2 and 3, the vehicle-mounted drone electromagnetic attraction and charging device of this embodiment also includes a fixed sleeve 4 for guiding the movable sleeve 3, and the fixed sleeve 4 is sleeved on the movable sleeve 3. The movable sleeve 3 and the fixed sleeve 4 move through a sliding groove to prevent the movable sleeve 3 from rotating during the lifting process, and the movable sleeve 3 can only move in a straight line in the vertical direction.
[0058] As shown in Figures 2 and 3, the lifting mechanism includes a drive motor and a transmission mechanism connected to the drive motor. In this embodiment, the transmission mechanism is a lead screw and nut mechanism. The output end of the drive motor is fixedly connected to the lead screw of the transmission mechanism, and the nut of the transmission mechanism is connected to the fixed sleeve 4. The lead screw and nut form a helical transmission.
[0059] Alternatively, the lifting mechanism may include a drive motor and a transmission mechanism. The fixed end of the drive motor is fixedly connected to the inner wall of the fixed sleeve 4, and the output end of the drive motor is connected to the transmission mechanism. The transmission mechanism may include a lead screw and a nut. The lead screw is coaxially arranged with and connected to the output end of the drive motor, and the nut is threadedly connected to the lead screw and to the movable sleeve 3. In this way, when the drive motor is working, the output end can drive the lead screw to rotate. Under the action of the threaded connection between the lead screw and the nut, the nut can move upward or downward as the lead screw rotates, thereby driving the movable sleeve 3 to move upward or downward.
[0060] As shown in Figures 2 and 3, the vehicle-mounted drone electromagnetic attraction and charging device of this embodiment also includes a support sleeve 5, which is fixedly mounted on the base. A fixed sleeve 4 is mounted on the support sleeve 5, and the support sleeve 5 and the fixed sleeve 4 can slide up and down to enhance the stability of the landing pad. The fixed sleeve 4 is driven to slide up and down by a lifting mechanism. The landing pad is supported by four lifting rods, which are distributed around the outer perimeter of the support sleeve 5. The lifting rods are relatively thin, and the entire landing pad is insufficient under impact load conditions. The middle sleeve plays a role in improving stability. When the four lifting rods extend upward, they will drive the landing pad and the fixed sleeve 4 to move upward, thereby driving the adsorption mechanism and the wireless charging module to move upward. Alternatively, when the four lifting rods retract downward, they will drive the landing pad and the fixed sleeve 4 to move downward, thereby driving the adsorption mechanism and the wireless charging module to move downward together.
[0061] As shown in Figure 5, the takeoff process for a vehicle-mounted drone includes the following steps:
[0062] Step 1: Input the launch command;
[0063] Step 2: Unlock the drone cabin door;
[0064] Step 3: Prepare to open the door of the unmanned aerial vehicle (UAV) cabin;
[0065] Step 4: Check if there are any obstacles in the door area of the unmanned vehicle cabin; if there are obstacles in the door area of the unmanned vehicle cabin, rotate the door a certain distance and then remove the obstacles.
[0066] Step 5: There are no obstacles in the door opening area of the drone cabin, and the drone cabin door is fully opened;
[0067] Step 6: The apron ascends;
[0068] Step 7: The clamping mechanism releases the drone;
[0069] Step 8: Electromagnet 2 is energized, and it separates from the drone. Then, control the electromagnet 2 to descend (the descent of the electromagnet 2 can be achieved by controlling the descent of the lifting mechanism).
[0070] Step 9: Launch the drone;
[0071] Step 10: The helipad descends to the bottom of the unmanned aerial vehicle (UAV) cabin;
[0072] Step 11: Prepare to close the door of the unmanned aerial vehicle (UAV) cabin;
[0073] Step 12: Check if there are any obstacles in the door closing area of the drone cabin; if there are obstacles in the door closing area of the drone cabin, reverse the cabin door a certain distance, and then remove the obstacles.
[0074] Step 13: There are no obstacles in the door closing area of the unmanned cabin, the cabin door is completely closed and locked.
[0075] As shown in Figure 6, the recall process for vehicle-mounted drones includes the following steps:
[0076] Step 1: Input the recycling command;
[0077] Step 2: Unlock the drone cabin door;
[0078] Step 3: Prepare to open the door of the unmanned aerial vehicle (UAV) cabin;
[0079] Step 4: Check if there are any obstacles in the door opening area of the drone cabin; if there are obstacles in the door opening area of the drone cabin, rotate the cabin door a certain distance and then remove the obstacles.
[0080] Step 5: There are no obstacles in the door opening area of the drone cabin, and the drone cabin door is fully opened;
[0081] Step 6: The apron ascends;
[0082] Step 7: Electromagnet 2 descends to avoid obstructing the drone's landing.
[0083] Step 8: The drone lands;
[0084] Step 9: The clamping mechanism clamps the drone;
[0085] Step 10: Electromagnet 2 rises. After electromagnet 2 is de-energized, electromagnet 2 attracts the drone. That is, when electromagnet 2 is not energized, it can continue to attract the drone.
[0086] Step 11: The helipad descends to the bottom of the unmanned aerial vehicle (UAV) cabin;
[0087] Step 12: Prepare to close the door of the unmanned aerial vehicle (UAV) cabin;
[0088] Step 13: Check if there are any obstacles in the closing area of the drone cabin; if there are obstacles in the closing area of the drone cabin, reverse the cabin door a certain distance, and then remove the obstacles.
[0089] Step 14: There are no obstacles in the closing area of the drone cabin. The drone cabin door is completely closed and locked.
