[0001] The utility model belongs to the technical field of unmanned aerial vehicles, and particularly relates to a long-endurance unmanned aerial vehicle for training. Background Art

[0002] An unmanned aerial vehicle, abbreviated as "UAV" and with the English abbreviation "UAV", is an unpiloted aircraft controlled by a radio remote control device and a self-provided program control device, or is completely or intermittently autonomously operated by an on-vehicle computer.

[0003] The UAVs currently used for training the driving skills of UAV pilots generally have a short endurance time. However, the vast majority of the weight in UAVs comes from the weight of the battery, and the prior art cannot make a major breakthrough in the battery quality. The above problems lead to a poor class experience for the trainees, insufficient or overly fragmented effective learning time. Therefore, it is necessary to design a long-endurance UAV for training to solve the problems of the prior art. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a long-endurance UAV for training to solve the problems mentioned in the background art.

[0005] To achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A long-endurance UAV for training, including a UAV body, and a power supply device is installed on the lower side of the UAV body;

[0007] The power supply device includes an L-shaped bearing seat, the L-shaped bearing seat is fixedly connected to the UAV body, a horizontally oriented sliding rod is installed on the rear side thereof, a battery frame is slidably connected to the upper side of the sliding rod, a baffle is installed on the front side of the L-shaped bearing seat, a control rod is connected to the lower side of the baffle, the control rod is vertically hinged to the bottom of the L-shaped bearing seat, a tension spring is installed between the rear side of the control rod and the L-shaped bearing seat, a plurality of battery compartments of the same size are jointly formed among the L-shaped bearing seat, the battery frame and the baffle, a rechargeable battery block matching the battery compartment is installed inside the battery compartment, a contact point is provided at the top of the rechargeable battery block, a contact component matching the contact point is installed at the bottom of the UAV body, and a control component for controlling the left and right movement of the battery frame is installed on the rear side of the L-shaped bearing seat.

[0008] The control component includes a lead screw, the lead screw is rotatably connected to the L-shaped bearing seat and is in threaded connection with the battery frame, a motor is installed on the side of the L-shaped bearing seat, and the output end of the motor is in transmission connection with the lead screw.

[0009] The contact component includes a contact piece, which is located on the upper side of the left part of the L-shaped carrier seat and is slidably connected to the bottom of the UAV body up and down. A return spring is connected to the upper side of the contact piece. The contact piece is matched with the contact point, and a chamfer is provided on the lower side of the contact piece.

[0010] The contact piece is a long piece oriented left and right.

[0011] A shock-absorbing piece is provided at the bottom of the rechargeable battery block.

[0012] A plurality of hollow slots are provided on the UAV body, the L-shaped carrier seat, and the upper side of the battery box.

[0013] Through the cooperation of the battery box and multiple rechargeable battery blocks, the UAV can reduce the overall weight of the batteries by removing the underpowered batteries, thereby reducing the flight burden of the UAV, making the UAV more flexible. At the same time, the UAV needs to consume less energy to maintain its flight state during flight, thereby extending the endurance time and improving the training experience of the trainees. The cooperation of the control rod and the tension spring enables the control baffle to fix the rechargeable battery block and facilitate the installation of the battery, improving the usability.

Specific implementation mode

[0022] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] As Figure 1-6 shown, a long-endurance drone for training includes a drone body 1, and a power supply device is installed on the lower side of the drone body 1;

[0024] The power supply device includes an L-shaped carrier 2, the L-shaped carrier 2 is fixedly connected to the drone body 1, a horizontally oriented slide bar 3 is installed on its rear side, a battery frame 4 is slidably connected to the upper side of the slide bar 3, a baffle 5 is installed on the front side of the L-shaped carrier 2, a control rod 6 is connected to the lower side of the baffle 5, the control rod 6 is vertically hinged to the bottom of the L-shaped carrier 2, a tension spring 7 is installed between the rear side of the control rod 6 and the L-shaped carrier 2, a plurality of battery compartments 8 of the same size are jointly formed among the L-shaped carrier 2, the battery frame 4 and the baffle 5, a rechargeable battery block 9 matching with the battery compartment 8 is installed inside the battery compartment 8, a contact point 10 is provided at the top of the rechargeable battery block 9, a contact assembly matching with the contact point 10 is installed at the bottom of the drone body 1, and a control assembly for controlling the left and right movement of the battery frame 4 is installed on the rear side of the L-shaped carrier 2.

[0025] When the present utility model is not in use, the control assembly positions the battery frame 4 directly above the L-shaped carrier 2. At this time, pressing the rear side of the control rod 6 causes the baffle 5 to open downward, and the rechargeable battery block 9 is installed inside the battery compartment 8 from the side at one time. At this time, the contact point 10 on the upper side of the leftmost rechargeable battery block 9 contacts the contact assembly, and the contact assembly is connected to the electrical equipment of the drone body 1.

[0026] When the usage time reaches a certain amount and the first rechargeable battery block 9 on the left has insufficient power, the drone body 1 can land close to a designated position on the ground, and the control assembly moves the battery frame 4 to the left. At this time, the bottom of the leftmost rechargeable battery block 9 leaves the L-shaped carrier 2 and slides downward, and then the contact point 10 of the adjacent rechargeable battery block 9 contacts the contact assembly, so that the drone body 1 can continue to fly normally.

[0027] Through the cooperation of the battery frame 4 and multiple rechargeable battery blocks 9, the drone can reduce the overall weight of the batteries by removing underpowered batteries, thereby reducing the flight burden of the drone, making the drone more flexible. At the same time, the drone consumes less energy during flight to maintain its flight state, thereby extending the endurance time and enhancing the training experience of trainees. The cooperation of the control lever 6 and the tension spring 7 enables the control baffle 5 to fix the rechargeable battery block 9 and facilitate battery installation, improving the convenience of use.

[0028] The control component includes a lead screw 11, which is rotatably connected to the L-shaped bearing seat 2 and threadedly connected to the battery frame 4. An electric motor 12 is installed on the side of the L-shaped bearing seat 2, and the output end of the electric motor 12 is drivingly connected to the lead screw 11.

[0029] The design of driving the battery frame 4 to move by rotating the lead screw 11 makes the structure of the control component simple, reliable, and lightweight. Due to the one-way locking characteristic of the lead screw 11, while enabling the control component to control the battery frame 4 more delicately, it can also prevent the battery frame 4 from displacing when the electric motor 12 is not working, improving the accuracy of the control component.

[0030] The contact component includes a contact piece 13, which is located on the upper side of the left part of the L-shaped bearing seat 2 and is slidably connected to the bottom of the drone body 1 in the vertical direction. A return spring 14 is connected to the upper side of the contact piece 13. The contact piece 13 is matched with the contact point 10, and a chamfer 15 is provided on the lower side of the contact piece 13.

[0031] The return spring 14 enables the contact piece 13 to keep in contact with the contact point 10 below it. The design of the chamfer 15 on the lower side of the contact piece 13 enables the rechargeable battery block 9 to be more conveniently installed inside the battery compartment 8, improving the convenience of use.

[0032] The contact piece 13 is a long piece oriented left and right.

[0033] The design of the contact piece 13 as a long piece enables the contact piece 13 to always be in contact with the rechargeable battery block 9 when the battery frame 4 moves, ensuring its reliability.

[0034] A shock-absorbing piece 16 is provided at the bottom of the rechargeable battery block 9.

[0035] The shock-absorbing piece 16 can protect the rechargeable battery block 9 when it falls, extending its service life.

[0036] A plurality of hollow slots 17 are provided on the upper sides of the drone body 1, the L-shaped bearing seat 2, and the battery frame 4.

[0037] The design of the hollow slots 17 reduces the self-weight of the drone while ensuring the structural strength of the drone, further improving the endurance ability of the drone.

[0038] The above embodiments merely illustrate the principles and effects of the present utility model by way of example, rather than limiting the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
