DETAILED DESCRIPTION

[0030] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] A high-power UAV airborne conversion device according to a preferred embodiment of the present invention will be described in detail below. Figure 1-2 As shown, a high-power UAV airborne conversion device includes a body 1, motors 2 are fixedly installed at the four corners of the top of the body 1, the top of the motor 2 is transmission-connected with a propeller 3, a connection control component 4 is arranged in the center of the bottom of the body 1, a power supply component 5 is arranged in the center of the bottom of the connection control component 4, the power supply component 5 is used for carrying and converting power, the connection control component 4 is used for loading the power supply component 5 and performing circuit control, and support legs 6 are evenly fixedly installed on the outer side of the frame 41 at the bottom of the body 1, and the support legs 6 are foldable in design and are used for parking and storing the UAV.

[0032] like Figure 3-6 As shown, the control assembly 4 includes a frame 41, the frame 41 is fixedly installed in the center of the bottom end of the body 1, and a control box 42 is fixedly installed at the top of the frame 41. The control box 42 is connected to the motor 2 and is used to control the motor 2. The positive and negative poles of the power connection sheet 43 are symmetrically fixedly installed on the left and right sides of the bottom end of the control box 42. The contact sheet 52 is aligned with the contact sheet 43. After the connection block 51 is plugged in, the contact sheet 52 and the contact sheet 43 can be squeezed and electrically connected, so that the power supply is Component 5 can supply energy to the drone through the control box 42. A placement slot 44 is opened in the center of the bottom of the frame 41. A limit plate 45 is fixedly installed around the placement slot 44 at the bottom end of the frame 41. The outer limit hinges of the limit plates 45 on the left and right sides are provided with buckles 46. A spring 49 is fixedly connected between the buckle 46 and the limit plate 45, and the spring 49 is located below the hinge between the buckle 46 and the limit plate 45, so that the buckle 46 can move inward at the top under the action of the spring 49.

[0033] A groove 47 is provided on the periphery of the buckle 46 on the limiting plates 45 on the left and right sides, so that the top of the buckle 46 can extend to the inner side of the limiting plate 45, and the bottom of the buckle 46 is inclined. A driving groove 48 is provided on the periphery of the buckle 46 at the bottom of the frame 41, so that the bottom of the buckle 46 extends downward to the bottom of the frame 41, and after the top of the buckle 46 extends to the inner side of the limiting plate 45, the driving groove 48 can limit the outer edge of the bottom of the buckle 46. Limiting grooves 518 are provided on the left and right sides of the connecting block 51, and the limiting of the connecting block 51 is achieved by the cooperation between the limiting grooves 518 and the buckle 46. Therefore, the top of the buckle 46 can remain stable after extending inward, and then cooperate with the limiting grooves 518 to limit the connecting block 51.

[0034] When it is necessary to plug in the onboard power supply, the connecting block 51 is inserted into the frame 41 from the bottom of the frame 41 through the placement slot 44 using the limit of the limit plate 45. During the insertion process, when the connecting block 51 contacts the buckle 46, the compression spring 49 at the bottom of the buckle 46 will rotate, thereby shrinking the top. When the connecting block 51 moves to the limit slot 518 and is aligned with the buckle 46, the buckle 46 will move inward at the top under the action of the restoring force of the spring 49, and then cooperate with the limit slot 518 to limit the connecting block 51, so as to achieve stable plugging of the power supply component 5. While completing the limitation, the contact sheet 52 can be squeezed into contact with the power connection sheet 43, thereby achieving electrical connection of the power supply component 5, and controlling the drone through the control box 42 to realize the function of the power supply component 5 for the drone.

[0035] When the onboard power supply needs to be removed, the buckle 46 is extended downward and the buckles 46 on both sides are pushed inward at the same time, so that the top of the buckle 46 is expanded to both sides, thereby releasing the limit on the connecting block 51, so that the connecting block 51 can be taken out downward.

[0036] like Figure 6-11 As shown, the power supply component 5 includes a connecting block 51, the connecting block 51 is inserted into the placement groove 44 at the bottom of the frame 41, and the electric shock sheets 52 are fixedly installed at the symmetrical depressions on the left and right sides of the bottom of the connecting block 51. The electric shock sheets 52 are aligned with the power connection sheet 43. After the connecting block 51 is inserted, the electric shock sheets 52 and the power connection sheet 43 can be squeezed and electrically connected. A power block 53 is fixedly installed at the bottom end of the connecting block 51, and mounting columns 54 are fixedly installed on the left and right sides of the power block 53 at the bottom end of the connecting block 51. The mounting columns 54 on both sides are symmetrically distributed front and back, and the front winding cylinder 55 is fixedly installed on the front and rear sides between the front and rear mounting columns 54 on the left and right sides, respectively. And the rear winding tube 56, the outer periphery of the front winding tube 55 and the rear winding tube 56 are respectively wound with the front coil 57 and the rear coil 58, a connecting column 59 is fixedly installed between the front winding tube 55 and the rear winding tube 56, the outer side of the connecting column 59 is limitedly slidably connected with an electric shock ring 510, and the inner side of the electric shock ring 510 is provided with an elastic sheet 5101 to ensure the stability of power connection, the front and rear ends of the electric shock ring 510 are fixedly connected with the front winding tube 55 and the rear winding tube 56 with a plastic spring 511, through the design of the plastic spring 511, the electric shock ring 510 can be maintained at the central position of the connecting column 59 when the front and rear sides are not subjected to force or the force is the same.

[0037] The front winding tube 55 and the rear winding tube 56 are made of insulating material, and iron cores are fixedly installed inside the front winding tube 55 and the rear winding tube 56. Therefore, when current passes through the front coil 57 and the rear coil 58, the front and rear ends of the front winding tube 55 and the rear winding tube 56 can better generate magnetism, thereby attracting the electric shock ring 510.

[0038] A main power supply 531 is fixedly placed inside the power block 53, an emergency power supply 532 is plugged in below the main power supply 531 inside the power block 53, and a cover plate 533 is fixedly installed below the emergency power supply 532 at the bottom of the power block 53. The connecting column 59 is made of insulating material and is divided into an insulating layer 591 on the rear side, a main power connection layer 592 in the middle and an emergency power connection layer 593 on the front side. The electric shock ring 510 is electrically connected to the electric shock sheet 52 through a wire one 512, the emergency power supply 532 passes through the front winding tube 55 through a wire two 513 to be electrically connected to the emergency power connection layer 593 and then to the front coil 57, the main power supply 531 passes through the rear winding tube 56 through a wire three 514 to be electrically connected to the main power connection layer 592 and then to the rear coil 58.

[0039] A front warning light 516 and a rear warning light 517 are fixedly installed on the front and rear sides of the connecting block 51 respectively. The front coils 57 on the left and right sides are electrically connected to the positive and negative electrodes of the front warning light 516 through the wire four 515, and the rear coils 58 on the left and right sides are electrically connected to the positive and negative electrodes of the rear warning light 517 through the wire four 515, so that the emergency power supply 532 can energize the front warning light 516 through the front coil 57, and the front warning light 516 is used to indicate whether the emergency power supply 532 has power, so that the main power supply 531 can energize the rear warning light 517 through the rear coil 58, and the rear warning light 517 is used to indicate whether the main power supply 531 has power.

[0040] During the use of the drone, when starting and standing by, the main power supply 531 and the emergency power supply 532 are enabled at the same time. The main power supply 531 energizes the rear prompt light 517 through the wire three 514 through the rear coil 58, and the rear prompt light 517 is used to indicate whether the main power supply 531 has power. The emergency power supply 532 energizes the front prompt light 516 through the wire two 513 through the front coil 57, and the front prompt light 516 is used to indicate whether the emergency power supply 532 has power.

[0041] When both the main power supply 531 and the emergency power supply 532 have power, current will flow through the front coil 57 and the rear coil 58 after the front warning light 516 and the rear warning light 517 are on. In conjunction with the action of the iron core inside the front winding tube 55 and the rear winding tube 56, and utilizing the principle of electromagnetism, the same attraction can be generated on the front and rear sides of the electric shock ring 510, and then in conjunction with the plastic spring 511, the electric shock ring 510 is located in the central position of the connecting column 59 to be electrically connected to the main power connection layer 592. Therefore, in conjunction with the electrical connection between the main power supply 531 and the main power connection layer 592 through the wire three 514, and the electrical connection between the electric shock ring 510 and the electric shock sheet 52 through the wire one 512, the main power supply 531 can power on the drone, thereby achieving the normal operation of the drone driven by the main power supply 531.

[0042] When the main power supply 531 loses power during the flight of the drone, the rear warning light 517 goes out, and no current flows through the rear coil 58. The emergency power supply 532 energizes the front warning light 516 normally, so that the electric shock ring 510 is attracted to move forward on the outside of the connecting column 59 under the action of the front coil 57 and the iron core electromagnetism, and the electric shock ring 510 is electrically connected to the emergency power connection layer 593. Therefore, with the electrical connection between the emergency power supply 532 and the emergency power connection layer 593 through the wire 2 513, and the electrical connection between the electric shock ring 510 and the electric shock sheet 52 through the wire 1 512, the emergency power supply 532 can energize the drone, and then the emergency power supply 532 can drive the drone to run and avoid a crash.

[0043] Before takeoff, when the emergency power supply 532 has no power, the electric shock ring 510 will be attracted by the rear coil 58 and the iron core electromagnetism to move backward on the outside of the connecting column 59, so that the electric shock ring 510 moves to the insulating layer 591, and the drone cannot be powered on. Therefore, the emergency power supply 532 cannot take off when it has no power, and the emergency power supply 532 must be inspected and repaired in time to ensure that the emergency power supply 532 functions normally.

[0044] During the landing process, the power supply to the motor 2 is stopped first, and then the main power supply 531 and the emergency power supply 532 simultaneously cancel the power supply to the rear indicator light 517 and the front indicator light 516. After being free from force, the electric shock ring 510 remains in the middle position of the connecting column 59 under the action of the plastic spring 511, which is convenient for the next power supply of the main power supply 531.

[0045] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
