Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and more specifically, relates to a multi-functional teaching UAV. Background Technology

[0002] Currently, unmanned aerial vehicle (UAV) systems used for flight service training generally suffer from high equipment damage rates, especially for components such as the propellers. The main reason for this is that trainees' operating skills are not yet proficient, easily leading to collisions due to improper operation, while existing UAVs lack effective protective measures. Current training UAVs typically use shock-absorbing structures such as pads and springs on the fuselage sidewalls to cope with collisions. However, this protection mechanism still has shortcomings: in frequent training collision scenarios, the propellers are often not adequately protected, and damage remains a significant issue.

[0003] Therefore, there is an urgent need to improve existing teaching and training drones so that they can not only effectively protect key components such as propellers from collision damage during teaching operations, but also integrate more functions to improve teaching effectiveness and practicality. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-functional teaching drone, which aims to solve the technical problem that existing teaching and training drones cannot simultaneously provide safety protection for the drone propellers and improve the drone's functionality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a multi-functional teaching drone, comprising:

[0006] The drone body, used for teaching, includes a body and multiple power components connected to the side of the body. The power components are connected to propellers and are used to drive the propellers to rotate so that the drone body can fly.

[0007] The propeller protection device consists of multiple sets, each connected at one end to the bottom of the UAV body. Each set of propeller protection devices has a degree of freedom of rotation in the vertical plane of the UAV body. When the UAV body is in flight, the multiple sets of propeller protection devices are located on the same horizontal plane as the multiple sets of propellers and are sleeved on the outer periphery of the propellers to protect the propellers. When the UAV body is falling, the propeller protection devices rotate toward the direction below the UAV body and gradually move away from the propellers to support the UAV body.

[0008] The machine body has an internal cavity, which is used to accommodate teaching aids.

[0009] In one possible implementation, the blade protection device includes:

[0010] The driver, connected to the bottom of the drone body, has a rotatable power output end;

[0011] The drive rods are multiple, and one end of each is connected to the power output end of the driver. The driver is used to drive the multiple drive rods to rotate simultaneously. The drive rods have rotational freedom in the vertical plane of the UAV body.

[0012] The collar has its outer wall connected to the other end of the plurality of drive rods. When the drive rods rotate, they can drive the collar to rise and fall, so that the collar moves to the outer periphery of the blade or moves to below the blade.

[0013] In one possible implementation, the drive rod is a telescopic rod whose length can be adjusted and locked.

[0014] In one possible implementation, the collar has a notch for avoiding the power assembly, and when the collar is placed on the outer periphery of the blade, the middle part of the power assembly is located inside the notch.

[0015] In one possible implementation, the UAV body is wirelessly connected to a remote controller, which has a control module for controlling the operation of the drive unit. The remote controller can control the raising and lowering of the collar to protect the propeller and support the UAV body.

[0016] In one possible implementation, a buffer pad is adhered to the outer wall of the collar, the buffer pad being used to cushion collisions between the collar and external objects.

[0017] In one possible implementation, the machine body is provided with a power supply, which is electrically connected to the plurality of drivers and is used to supply power to the plurality of drivers respectively.

[0018] In one possible implementation, the body includes a power compartment and a receiving compartment located on top of the power compartment. The cavity is located inside the receiving compartment, and the top of the receiving compartment has a compartment opening. The receiving compartment is connected to a cover, which is used to cover the compartment opening.

[0019] In one possible implementation, the compartment is internally connected to a plurality of telescopic top columns, the upper ends of which are connected to the cover and used to drive the cover to rise and fall, thereby opening or closing the compartment opening.

[0020] In one possible implementation, a cushioning cotton is connected to the upper end of the cover, which is used to cushion the collision between the top of the body and external objects.

[0021] The beneficial effects of this utility model of a multi-functional teaching drone are as follows: Compared with the prior art, this utility model of a multi-functional teaching drone includes a drone body and a propeller protection device. The propeller protection device consists of multiple sets, each connected at one end to the bottom of the drone body. Each set of propeller protection devices has a degree of freedom of rotation in the vertical plane of the drone body. When the drone body is in flight, the multiple sets of propeller protection devices are located on the same horizontal plane as the multiple sets of propellers and are sleeved on the outer periphery of the propellers to protect them. When the drone body is falling, the propeller protection devices rotate toward the direction below the drone body and gradually move away from the propellers to support the drone body. At the same time, there is a cavity inside the body that can be used to accommodate teaching tools, so that the teaching and training drone can both protect the drone propellers and improve the drone's functionality, teaching effectiveness, and practicality.

[0032] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] Please refer to the following: Figures 1 to 5 This invention provides a description of a multifunctional teaching drone. The multifunctional teaching drone includes a drone body 1 and propeller protection devices 2. The drone body 1 is used for teaching and includes a fuselage 11 and multiple power components 12 connected to the side of the fuselage 11. The power components 12 are connected to propellers 13 and are used to drive the propellers 13 to rotate, enabling the drone body 1 to fly. Multiple sets of propeller protection devices 2 are connected at one end to the bottom of the drone body 1. Each set of propeller protection devices 2 has a degree of freedom of rotation in the vertical plane of the drone body 1. When the drone body 1 is flying, the multiple sets of propeller protection devices 2 are located on the same horizontal plane as the multiple sets of propellers 13 and are sleeved around the outer periphery of the propellers 13 to protect them. When the drone body 1 falls, the propeller protection devices 2 rotate downwards towards the drone body 1 and gradually move away from the propellers 13 to support the drone body 1. The fuselage 11 has an internal cavity 14 for accommodating teaching aids.

[0034] This utility model provides a multi-functional teaching drone. Compared with the prior art, by adding multiple sets of propeller protection devices 2 to the bottom of the drone body 1, multiple sets of propeller blades 13 can be protected one by one. When the drone body 1 is in flight, it can protect the propeller blades 13, and when the drone body 1 is falling, it can also support the drone body 1 (the bottom of the propeller protection device 2 can contact the ground, and by having multiple sets of propeller protection devices 2 in contact with the ground, it can support the drone body 1, at which time the drone body 1 is in an off-ground state). That is, the propeller protection device 2 in this utility model has two functions. Moreover, a cavity 14 is set inside the body 11 to accommodate teaching tools, so that the teaching and training drone can both protect the drone propeller blades 13 and improve the drone's functionality, thereby improving the teaching effect and practicality.

[0035] In this embodiment, the drone body 1 is a teaching drone in the prior art. The power component 12 is a drive motor, which is connected to the body 11 via support rods 15 (the support rods 15 are connected to the four corners of the body 11). In this embodiment, four sets of power components 12 are provided at the bottom of the body 11, and four sets of propeller protection devices 2 are correspondingly provided. Each set of propeller protection devices 2 protects one set of propeller blades 13. During the protection process, it will not come into contact with the propeller blades 13, effectively protecting the propeller blades 13 and preventing damage. The cavity 14 of the body 11 can be used to place teaching tools, such as a measuring ruler, spare propeller blades 13, spare batteries, screwdrivers, multimeters, etc., which can all be installed inside the cavity 14, saving space and facilitating storage, organization, and later use.

[0036] In some embodiments, please refer to Figures 1 to 4 The propeller protection device 2 includes a driver 21, a drive rod 22, and a collar 23. The driver 21 is connected to the bottom of the UAV body 1 and has a rotatable power output end. There are multiple drive rods 22, and one end of each drive rod is connected to the power output end of the driver 21. The driver 21 is used to drive multiple drive rods 22 to rotate simultaneously. The drive rods 22 have a degree of freedom of rotation in the vertical plane of the UAV body 1. The outer wall of the collar 23 is connected to the other end of the multiple drive rods 22. After the drive rods 22 rotate, they can drive the collar 23 to rise and fall, so that the collar 23 moves to the outer periphery of the propeller blade 13 or moves to below the propeller blade 13. The driver 21 is a drive motor or a geared motor, whose power output end can rotate, or rotate or oscillate within a certain rotation angle range. Since the power component 12 is located on the side of the body 11 and is horizontally arranged, in this embodiment, the rotation angle of the driver 21 is less than 90°, that is, the rotation angle of the drive rod 22. When the collar 23 rotates to its highest point, the drive rod 22 is in a horizontal state, and the collar 23 can fit around the outer circumference of the propeller 13, effectively protecting the propeller 13. When the drive rod 22 rotates downward, the collar 23 gradually moves away from the propeller 13. This action is activated when the UAV body 1 falls. When the drive rod 22 rotates from a horizontal state to a state of approximately 30°-90°, the four collars 23 are equivalent to the four "legs" of the UAV body 1, thus providing support for the UAV body 1.

[0037] In this embodiment, the following situations may occur: one is that a part of the bottom end of the collar 23 contacts the ground, and the other is that the entire bottom surface of the collar 23 contacts the ground. Neither of these situations will affect the support effect on the UAV body 1.

[0038] Specifically, one end of the drive rod 22 is fixedly connected to the power output end of the driver 21, allowing the driver 21 to drive the drive rod 22 to rotate or swing within a certain angle range. The other end of the drive rod 22 can be rotatably connected (rotating within a range of less than 45°) or fixedly connected to the collar 23. If rotatably connected, the collar 23 is allowed to swing within a certain angle range without affecting the protection of the blade 13. In other words, if the collar 23 is not horizontal, but tilted, it still provides some protection for the blade 13 when it is wrapped around it. Therefore, in the above embodiment, whether the drive rod 22 and the collar 23 are rotatably or fixedly connected, effective protection of the blade 13 can be achieved. In this embodiment, one driver 21 is equipped with two sets of drive rods 22, located on both sides of the collar 23, and the two sets of drive rods 22 rotate or swing simultaneously.

[0039] The distance between the multiple propeller blades 13 and the fuselage 11 is the same. To ensure effective protection for the propeller blades 13 located at different positions, in some embodiments, please refer to... Figures 1 to 4 The drive rod 22 is a telescopic rod, and its length can be adjusted and locked. This adjustable and locked length allows for adjustment of the position of the collar 23 around the blade 13, thus providing effective protection for the blade 13 at different locations.

[0040] In actual operation, first measure the distance between the blade 13 and the body 11, and then adjust the length of the drive rod 22 appropriately so that the center of the collar 23 and the center of the blade 13 are approximately at the same center point, so that the collar 23 can effectively protect the blade 13.

[0041] In some embodiments, please refer to Figures 1 to 5 The collar 23 has a notch 24 for avoiding the power assembly 12. When the collar 23 is placed on the outer periphery of the blade 13, the middle part of the power assembly 12 is located inside the notch 24. The power assembly 12 is connected to the body 11 by a support rod 15. In this embodiment, the support rod 15 is set in an approximately horizontal position, allowing the collar 23 to fit around the blade 13. Therefore, by setting the notch 24 on the collar 23 near the support rod 15, the collar 23 can be positioned to the maximum extent on the outer periphery of the blade 13, thus effectively protecting the blade 13. The depth or height of the notch 24 is less than the height of the collar 23, so that the collar 23 will not break and will remain circular. When the drive rod 22 rotates upward and the collar 23 is located on the outer periphery of the blade 13, the middle part of the support rod 15 can be inserted into the notch 24, thus avoiding the support rod 15 and ensuring the effective protection of the blade 13 by the collar 23.

[0042] In some embodiments, please refer to Figures 1 to 5The drone body 1 is wirelessly connected to a remote controller 3. The remote controller 3 has a control module for controlling the operation of the drive unit 21. The remote controller 3 can control the raising and lowering of the collar 23 to protect the propeller blades 13 and support the drone body 1. This remote controller 3 is existing technology and can achieve remote communication with the drone body 1. In addition to controlling the operation of the drone body 1, the remote controller 3 also has a control module for controlling the operation of the drive unit 21, which in turn controls the rotation of the drive rod 22 and the raising and lowering of the collar 23, thus enabling remote control of actions such as protecting the propeller blades 13.

[0043] The control module in this embodiment is a control unit in the prior art, including control buttons, control circuits, etc., which is electrically connected to the control chip inside the remote controller 3, so that it can control the raising and lowering of the collar 23 on the remote controller 3.

[0044] In some embodiments, please refer to Figures 1 to 4 A buffer pad 25 is adhered to the outer wall of the collar 23. The buffer pad 25 is used to buffer the collar 23 from collisions with external objects. The buffer pad 25 can reduce the collisions or impacts between the UAV body 1 and external objects (such as walls) during flight, thus playing a protective and buffering role and preventing damage to the collar 23 and the propeller 13. The buffer pad 25 is annular and fits onto the outer circumferential wall of the collar 23.

[0045] In some embodiments, please refer to Figure 2 Hezhi Figure 4 The body 11 contains a power supply 4, which is electrically connected to multiple actuators 21 and supplies power to each actuator 21. The power supply 4 is a rechargeable battery that supplies power to the actuators 21. The location of the power supply 4 does not affect the arrangement of the internal structures or components of the body 11, i.e., it does not affect the operation of the UAV body 1. The power supply 4 is a rechargeable battery.

[0046] In some embodiments, please refer to Figure 1 Figure 2 , Figures 4 to 5 The body 11 includes a power compartment 111 and a receiving compartment 112 located on top of the power compartment 111. A cavity 14 is located inside the receiving compartment 112. The top of the receiving compartment 112 has a compartment opening 113. The receiving compartment 112 is connected to a cover 114, which is used to seal the compartment opening 113. A power supply 4 is located inside the power compartment 111. A support rod 15 is connected to the side of the power compartment 111. The receiving compartment 112 is a cavity 14 used to hold or place teaching aids. The shape and size of the compartment opening 113 match the shape and size of the cover 114, and the cover 114 can completely close the compartment opening 113.

[0047] In some embodiments, please refer to Figure 5 The receiving compartment 112 has multiple telescopic top columns 115 connected inside. The upper end of each telescopic top column 115 is connected to a cover 114 and is used to drive the cover 114 to rise and fall, thereby opening or closing the compartment opening 113. The telescopic top columns 115 are telescopic and adjustable, thus satisfying the raising and lowering adjustment of the cover 114. When the cover 114 rises, the compartment opening 113 can be opened, making it easy to put objects into the cavity 14; when the cover 114 falls, the compartment opening 113 is closed, thus forming a closed space inside the cavity 14. Preferably, the telescopic top column 115 is an electric telescopic rod, which is electrically connected to the remote control 3 and the power supply 4. The power supply 4 can provide power to the telescopic top column 115. By operating the remote control 3, the telescopic top column 115 can be extended and retracted, thereby controlling the opening or closing of the cover 114.

[0048] Preferably, during the flight of the drone body 1, to prevent the top of the drone body 1 from colliding with or hitting external objects, the telescopic top column 115 can be extended to raise the cover 114, allowing the upper part of the cover 114 to touch the external object, effectively preventing collisions or damage to the drone body 1. The cover 114 is replaceable and removable; when damaged, it can be removed and replaced with a new cover 114, thus avoiding the greater cost of repairing the drone body 1 after damage.

[0049] During the flight of the drone body 1, in order to prevent the upper part of the cover 114 from touching external objects and to buffer the body 11, in some embodiments, please refer to... Figure 5 A cushioning cotton 116 is connected to the upper end of the cover 114. The cushioning cotton 116 is used to cushion the collision between the top of the drone body 11 and external objects. The cushioning cotton 116 is a structural component with a cushioning function. It is pasted on the upper end of the cover 114 and can effectively play a role in cushioning and shock absorption to avoid the upper end or top of the drone body 1 from colliding with objects, thus effectively protecting the drone body 1.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
