[0051] A control device 1 and an auxiliary take-off device, wherein the auxiliary take-off device includes a take-off base 2 provided on a vehicle and a connecting bracket 3 provided at the bottom of a UAV 21, wherein the take-off base 2 is used to dock with the connecting bracket 3 to allow the UAV 21 to dock;

[0052] A retractable assembly is provided in the take-off base 2, and the retractable assembly is arranged near the contact position between the take-off base 2 and the connecting bracket 3. The retractable assembly is used to assist the connecting bracket 3 in docking with the take-off base 2 for the UAV 21 to dock, or to contact the connecting bracket 3 and apply an upward thrust to the connecting bracket 3 to assist the UAV 21 in taking off.

[0053] Reference Figure 7 The control device 1 is connected to the vehicle bus, and the control device 1 is electrically connected to the retractable component. The control device 1 assists the drone 21 in docking or taking off through the retractable component.

[0054] Through the above arrangement, firstly, the takeoff base 2 provided on the vehicle is used to dock with the connecting bracket 3 under the drone 21. When the takeoff base 2 and the connecting bracket 3 are docked, the drone 21 can be docked on the vehicle. The retractable assembly provided within the takeoff base 2 can assist the drone 21 during takeoff, solving the problem of insufficient lift during takeoff. With the assistance of the retractable assembly, the drone 21 can be launched higher and away from the roof of the vehicle at the beginning of takeoff, effectively avoiding the possibility of the drone 21 being released while the vehicle is in motion and causing a collision with the drone 21.

[0055] On the other hand, the control device 1 is electrically connected to the retractable assembly, and the control device 1 is connected to the vehicle bus, so that the user can control the retractable assembly in the car through the device connected to the vehicle bus, so as to assist in the launch of the drone 21 or assist in the recovery of the drone 21, which greatly increases the use scenarios of the drone 21 and reduces the risks that may exist when the user releases the drone 21 outside the car.

[0056] In the examples of this application, refer to Figure 3 and Figure 4 The connecting bracket 3 includes a connecting seat 301 and a plurality of bracket legs 302 connected to the connecting seat 301. The take-off base 2 is provided with leg slots 4 having the same number as the plurality of bracket legs 302, and the leg slots 4 are for inserting the bracket legs 302.

[0057] The take-off base 2 is provided with a positioning column 6, and the bottom of the connecting seat 301 is provided with a positioning groove 7 that is plugged into and matched with the positioning column 6;

[0058] When the connecting bracket 3 is docked with the take-off base 2 , the positioning column 6 is inserted into the positioning groove 7 , and the bracket leg 302 is inserted into the leg groove 4 .

[0059] Reference Figure 3 and Figure 4 The leg slots 4 are for inserting the bracket legs 302, and the number of the leg slots 4 corresponds to the number of the bracket legs 302. During the recovery process of the UAV 21, the bracket legs 302 are inserted into the leg slots 4 for placement; the positioning slots 7 are for inserting the positioning posts 6, and the positioning slots 7 and the positioning posts 6 are plugged in and matched to fix the connecting bracket 3 as a whole, ensuring that the UAV 21 and the connecting bracket 3 as a whole can be stably fixed on the vehicle.

[0060] In an embodiment of the present application, the drone 21 is fixedly connected to the connecting seat 301, wherein the drone 21 and the connecting seat 301 are fixed by multiple bolts, and the multiple bolts are inserted through the bottom threads of the connecting seat 301 into the bottom of the drone 21, thereby achieving the fixation of the drone 21 and the connecting bracket 3.

[0061] In some embodiments of the present application, the connection between the drone 21 and the connection seat 301 can also be bonding, clamping, riveting, welding or integrated molding, which is not specifically limited here.

[0062] In the examples of this application, refer to Figure 3 and Figure 4 The connecting seat 301 includes a positioning cylinder with a protruding bottom (not shown in the figure), wherein the positioning groove 7 is opened in the positioning cylinder. After the drone 21 is recovered, the positioning groove 7 in the positioning cylinder is plugged into the positioning column 6.

[0063] In the examples of this application, refer to Figure 3 and Figure 4 The number of support legs 302 can be four, and each of the four support legs 302 is connected to the connecting base 301. The connecting base 301 is a square plate. The four support legs 302 are connected to the four corners of the connecting base 301 and are symmetrically arranged with the center of the connecting base 301 as the axis. The four support legs 302 serve to support the connecting base 301 and the drone 21 on the connecting base 301.

[0064] The four support legs 302 are arranged at an inclined angle to the ground to form a triangle with the ground and the vertical line, thereby enhancing the stability of the support.

[0065] In some embodiments of the present application, the connection between the bracket leg 302 and the connecting seat 301 can also be bonding, clamping, riveting, welding or integral molding, which is not specifically limited here.

[0066] In the examples of this application, refer to Figure 3 and Figure 4 The bracket leg 302 includes a connected inclined portion 3021 and a contact portion 3022, wherein the inclined portion 3021 is inclined, the length direction of the contact portion 3022 is perpendicular to the ground, and the contact portion 3022 is used to be inserted into the leg slot 4 for fixation.

[0067] In the embodiment of the present application, the bottom of the contact portion 3022 is disc-shaped. The disc-shaped contact portion 3022 is used to increase the contact area of ​​the contact surface, thereby better maintaining the stability of the connecting bracket 3 and the drone 21 on the connecting bracket 3.

[0068] To assist the takeoff and recovery of UAV 21, the following is performed:

[0069] Reference Figure 1 and Figure 2 , the retractable assembly includes:

[0070] A mounting hole 8 communicating with the side wall of the leg slot 4;

[0071] A booster spring 9, one end of which is connected to the bottom of the leg slot 4, and the other end is used to contact the bottom of the bracket leg 302.

[0072] A C-shaped plate 11 is provided in the takeoff base 2, and a swing plate 10 is provided on the C-shaped plate 11, wherein the middle portion of the swing plate 10 is rotatably connected to the C-shaped plate 11, one end of the swing plate 10 is located in the takeoff base 2, and the other end extends into the leg slot 4 through the mounting hole 8, and the bracket leg 302 is provided with a plug slot 13 for plugging with the swing plate 10;

[0073] An electric suction component is provided near the C-shaped plate 11, and is used to rotate the end of the swing plate 10 located in the take-off base 2 downward so that the end of the swing plate 10 located in the leg slot 4 rotates upward; or to rotate the end of the swing plate 10 located in the take-off base 2 upward so that the end of the swing plate 10 located in the leg slot 4 is inserted into the plug-in slot 13, so that the booster spring 9 is in a compressed state.

[0074] Reference Figure 1 and Figure 2 Since the support legs 302 are inserted into the leg slots 4, the support legs 302 in the leg slots 4 are assisted when the UAV 21 is launched, which can help the UAV 21 as a whole to be launched.

[0075] A booster spring 9 is disposed within the leg slot 4 and in contact with the contact portion 3022 of the support leg 302. When compressed, the booster spring 9 provides an upward force to the contact portion 3022 of the support leg 302, thereby assisting the takeoff of the drone 21. A swing plate 10, pivotally connected to the C-shaped plate 11, extends into the leg slot 4. The length of the swing plate 10 extending into the leg slot 4 interferes with the support leg 302 inserted into the leg slot 4.

[0076] Reference Figure 1 and Figure 2 When the drone 21 is recovered, the swing plate 10 is pushed by the bracket leg 302 and swings downward. After the swing plate 10 returns to a horizontal state, the swing plate 10 is located above the disc-shaped contact portion 3022 of the bracket leg 302. Under the action of the electric suction component, the end of the swing plate 10 is inserted into the plug-in slot 13, and the swing plate 10 has a downward thrust on the disc-shaped contact portion 3022 of the bracket leg 302, thereby compressing the assist spring 9, thereby achieving the fixation of the bracket leg 302, so that the bracket leg 302 can be fixed in the leg slot 4.

[0077] The compressed assist spring 9 has an elastic restoring force to return to its initial state. When the drone 21 needs to be launched, under the action of the electric suction component, the swing plate 10 swings upward and out of the plug-in slot 13. At this time, under the restoring force of the assist spring 9, the bracket leg 302 is pushed upward, so it bounces off the take-off base 2, thereby assisting the drone 21 in taking off.

[0078] In the examples of this application, refer to Figure 1 and Figure 2 The end of the swing plate 10 extending into the leg slot 4 is provided with an inclined surface 23, which faces the support leg 302. The arrangement of the inclined surface 23 facilitates the downward movement of the contact portion 3022 of the support leg 302. During the process of recovering the drone 21, the arrangement of the inclined surface 23 facilitates the downward swinging of the support leg 302 during the insertion into the leg slot 4.

[0079] In the examples of this application, refer to Figure 1 and Figure 2 , the take-off base 2 includes:

[0080] A main body base 201 and multiple fixing cylinders 202. The bottom of the main body base 201 is used to be installed on a vehicle. A mounting cavity 5 is formed in the main body base 201. The main body base 201 is formed with multiple fixing holes connected to the mounting cavity 5. The multiple fixing holes are used to install the multiple fixing cylinders 202. The leg slots 4 are opened on the fixing cylinders 202.

[0081] The fixing column is disposed on the upper surface of the main base 201 .

[0082] In the examples of this application, refer to Figure 1 and Figure 2 The number of the fixing tubes 202 is four, and the number of the fixing tubes 202 is the same as the number of the bracket legs 302, so as to accommodate all the bracket legs 302. The fixing tubes 202 penetrate the fixing holes and extend into the interior of the installation cavity 5, ensuring the flatness of the main base 201.

[0083] In an embodiment of the present application, the main base 201 can be installed on the roof of a vehicle to facilitate the launch or recovery of the drone 21.

[0084] In the embodiment of the present application, the upper edge of the fixing cylinder 202 is fixed to the main base 201 by bolts.

[0085] In the examples of this application, refer to Figure 1 and Figure 2 The C-shaped plate 11 includes an upper transverse plate 1101, a vertical plate 1102, and a lower transverse plate 1103. The upper transverse plate 1101 and the lower transverse plate 1103 are connected by the vertical plate 1102. The swing plate 10 is rotatably connected to the vertical plate 1102 and is located between the upper transverse plate 1101 and the lower transverse plate 1103. The electric suction component includes:

[0086] a tension spring 12, one end of which is connected to the upper horizontal plate 1101, and the other end of which is connected to the end of the swing plate 10 located inside the take-off base 2. The tension spring 12 is used to insert the end of the swing plate 10 into the insertion slot 13, so that the booster spring 9 is in a compressed state;

[0087] An electric suction device 14 is provided on the lower horizontal plate 1103. A metal sheet 15 is provided on the end of the swing plate 10 located within the takeoff base 2, facing away from the tension spring 12. The electric suction device 14 is configured to attract the metal sheet 15 when power is applied, thereby causing the end of the swing plate 10 located within the takeoff base 2 to rotate downward.

[0088] The electric suction device 14 is electrically connected to the control device 1 .

[0089] The C-shaped plate 11 is positioned within the mounting cavity 5. The upper horizontal plate 1101 of the C-shaped plate 11 is secured to the top wall of the mounting cavity 5 with bolts. The vertical plates 1102 of the C-shaped plate 11 are vertical, with the upper ends of the vertical plates 1102 connected to the horizontal plates and the lower ends of the vertical plates 1102 connected to the lower horizontal plates 1103, forming a C-shaped structure.

[0090] With the above settings, refer to Figure 1 and Figure 2During the recovery of the drone 21, the tensioning spring 12 is used to provide a restoring force for the end of the swing plate 10 located in the take-off base 2. When the bracket leg 302 is inserted into the leg slot 4, the end of the swing plate 10 located in the leg slot 4 will be pushed to rotate downward. At this time, the end of the swing plate 10 located in the take-off base 2 swings upward, causing the tensioning spring 12 to be compressed. After the contact portion 3022 of the bracket leg 302 is inserted into the leg slot 4, under the restoring force of the tensioning spring 12, the swing plate 10 tends to return to a horizontal state. When the swing plate 10 returns to a horizontal state and is inserted into the plug-in slot 13 of the leg bracket, the tensioning spring 12 presses the bracket leg 302 downward through the swing plate 10, causing the assist spring 9 to be compressed, thereby achieving fixed recovery of the drone 21.

[0091] Reference Figure 1 and Figure 2 During the launch of the drone 21, the control device 1 controls the electric suction device 14 to be energized. After being energized, the electric suction device 14 generates magnetic force, attracting the metal sheet 15 on the swing plate 10, causing the end of the swing plate 10 located in the take-off base 2 to move downward, thereby causing the end of the swing plate 10 located in the leg slot 4 to lift upward. The compressed assist spring 9 pushes the bracket leg 302 to bounce upward, thereby achieving the launch of the drone 21.

[0092] The swing plate 10 is rotatably connected to the vertical plate 1102 as follows:

[0093] In the examples of this application, refer to Figure 5 A swing hole 16 is opened in the middle of the vertical plate 1102, and a rotating shaft 17 is rotatably connected to the middle of the vertical plate 1102. The rotating shaft 17 penetrates from one side of the vertical plate 1102 and penetrates into the other side of the vertical plate 1102 through the swing hole 16. The swing plate 10 is fixedly connected to the rotating shaft 17 and is located in the swing hole 16.

[0094] To improve the drainage effect of the take-off base 2, refer to Figure 1 and Figure 2 ,as follows:

[0095] In the embodiment of the present application, a first drainage hole 18 communicating with the installation cavity 5 is formed at the bottom of the leg groove 4 to drain rainwater flowing into the leg groove 4 into the installation cavity 5;

[0096] A second drainage hole 19 communicating with the outside is defined at the bottom of the installation cavity 5 . The second drainage hole 19 is used to drain rainwater from the installation cavity 5 .

[0097] With the above settings, refer to Figure 1 and Figure 2In rainy weather, rainwater will flow into the leg slot 4. The rainwater can be guided into the installation cavity 5 through the first drainage hole 18 set in the leg slot 4, and finally discharged through the second drainage hole 19 on the installation cavity 5, preventing the equipment from being soaked in the accumulated rainwater for a long time and causing rust or damage.

[0098] In the examples of this application, refer to Figure 1 and Figure 2 A position radar 20 is provided in the installation cavity 5. The position radar 20 is used to obtain the position information of the drone 21. The output end of the position radar 20 is connected to the input end of the control device 1 to transmit the position information to the vehicle bus through the control device 1.

[0099] Reference Figure 1 and Figure 2 The positioning post 6 is set at the center of the upper surface of the main base 201, and the position radar 20 is set on the top wall of the installation cavity 5 and is located directly below the positioning post 6. The position radar 20 set here can not only play a rainproof effect, but also maintain a good signal.

[0100] In the embodiment of the present application, the position radar 20 emits electromagnetic wave energy into the external space through an antenna. Objects in the external space reflect the electromagnetic waves, which are then received by the radar antenna. The device processes the reflected electromagnetic waves and obtains information such as the distance between the target and the emission point, the rate of change of distance (movement speed), direction, and altitude. After the drone 21 is launched, the position radar 20 can obtain the drone 21's position information, including the distance between the drone 21 and the launch base 2, the rate of change of distance (movement speed), direction, and altitude.

[0101] In some embodiments of the present application, a distance sensor or a collection camera may also be provided on the take-off base 2 to collect the position information between the UAV 21 and the take-off base 2 .

[0102] In the examples of this application, refer to Figure 7 , the system further comprises:

[0103] a display device, the display device including a touch screen, the output end of the touch screen being connected to the vehicle bus via the vehicle host, so as to transmit instructions on the touch screen to the control device 1 via the vehicle host and the vehicle bus, so as to control the control device 1;

[0104] An input end of the display device is connected to an output end of the control device 1 so as to transmit the position information of the control device 1 to the position radar 20 and display the position information on the display device.

[0105] In the examples of this application, refer to Figure 7 The touch screen can be set as a vehicle-mounted screen. Since the touch screen is connected to the host of the vehicle computer, and the host of the vehicle is connected to the control device 1 through the vehicle bus, the user can directly control the takeoff and recovery of the drone 21 by operating the touch screen.

[0106] At the same time, since the position radar 20 is connected to the vehicle bus through the control device 1, refer to Figure 7 The vehicle bus can present the location information obtained by the position radar 20 on the touch screen through the vehicle's host, making it convenient for users to monitor the flight status of the drone 21 in real time in the vehicle.

[0107] In the examples of this application, refer to Figure 1 The system further includes a charging device 22 , which is disposed on the take-off base 2 . After the drone 21 docks on the take-off base 2 , the charging device 22 can dock with the charging port of the drone 21 for charging.

[0108] The charging device 22 is electrically connected to the control device 1. Figure 7 , so as to send remote instructions to the charging device 22 through the control device 1, thereby controlling the charging of the drone 21.

[0109] In the examples of this application, refer to Figure 7 The system also includes a vehicle-mounted T-BOX, which is connected to the vehicle's host. The user's mobile terminal (such as a mobile phone) can be connected to the vehicle's host through the vehicle-mounted T-BOX. The mobile phone is equipped with an APP for controlling the drone 21, thereby realizing the control of the takeoff and recovery of the drone 21 through the mobile phone.

[0110] In the embodiment of the present application, the recovery of the drone 21 includes manual recovery and remote control recovery, as follows:

[0111] During manual recovery, the bracket legs 302 on the connecting bracket 3 are aligned with the leg slots 4 one by one, and the positioning main is aligned and inserted into the positioning slot 7 until the swing plate 10 is plugged into the plug-in slot 13 to complete the positioning lock, thus completing the manual recovery of the drone 21.

[0112] In remote control recovery, refer to Figure 6 , set the position of the positioning column 6 as point A, and select two diagonal positions as points B / C. After the drone 21 takes off, the position radar 20 tracks the positioning groove 7 and the position information of the contact part 3022 of the bracket leg 302 corresponding to the BC position.

[0113] When the position radar 20 receives the reflected information, it executes the following steps:

[0114] 1. Control the drone 21 to descend to a height of H1 + 0.5 m ± 0.1 m from the vehicle's roof (to prevent the vehicle from moving and hitting the drone 21);

[0115] 2. After completing step 1, control the UAV 21 to move horizontally so that the horizontal distance between the positioning slot 7 and point A is within the range of ±0.2CM;

[0116] 3. After completing step 2, control the drone 21 to keep it suspended and rotate it around point A. The preferred rotation speed is 20° / s.

[0117] 4. During the rotation of the drone 21, when the horizontal distance between positions B and C and the contact portion 3022 of the corresponding support leg 302 is within the range of ±0.2CM, the alignment operation is completed;

[0118] 5. After completing step 4, control the drone 21 to slowly descend, preferably at a speed of 2 cm / s;

[0119] 6. When the position radar 20 detects that the bottom plane of the contact portion 3022 of the bracket leg 302 is located below the upper surface of the top of the main base 201, the position confirmation is completed;

[0120] 7. After completing step 6, control the drone 21 to run at the highest speed for 3 seconds or longer to ensure that the contact portion 3022 of the support leg 302 drops a distance sufficient to lock the swing plate 10, then stop the drone to complete the recovery.

[0121] Preferably, when performing subsequent steps, the control device 1 performs dynamic correction according to changes in wind speed and vehicle speed.

[0122] When the position radar 20 detects that the relative position of the contact portion 3022 of the bracket leg 302 and the corresponding A, B, and C is consistent with that at takeoff, the output is a recovery completion signal, which is transmitted to the vehicle's host and finally notified in the form of sound or image information through a mobile phone APP or display device.

[0123] Based on the same inventive concept, another embodiment of the present application provides a vehicle, which includes the vehicle-mounted drone 21 auxiliary take-off system as described above.

[0124] In general, the embodiments of the present application have the following advantages:

[0125] First, the takeoff base 2 mounted on the vehicle is used to dock with the connecting bracket 3 under the drone 21. When docked, the drone 21 can be docked on the vehicle. The retractable assembly within the takeoff base 2 assists the drone 21 during takeoff, resolving the issue of insufficient lift during takeoff. With the assistance of the retractable assembly, the drone 21 can be launched higher and away from the vehicle's roof during the initial takeoff phase, effectively preventing the drone 21 from colliding with the vehicle due to the vehicle being released while in motion.

[0126] On the other hand, the control device 1 is electrically connected to the retractable assembly, and the control device 1 is connected to the vehicle bus, so that the user can control the retractable assembly in the car through the device connected to the vehicle bus, so as to assist in the launch of the drone 21 or assist in the recovery of the drone 21, which greatly increases the use scenarios of the drone 21 and reduces the risks that may exist when the user releases the drone 21 outside the car.
