Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a multi-functional emergency rescue UAV with both land and air capabilities. Background Technology

[0002] Most existing drones can only fly in the air and cannot be used for both land and air purposes. The few drones that can be used for both land and air purposes have added land walking devices, which makes the entire drone's drive mechanism more complex, increases the drone's load, and reduces the drone's cruising capability. Therefore, it is necessary to improve them. Utility Model Content

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A multi-functional emergency rescue drone with both land and air modes includes: a fuselage module and a wing module.

[0006] The wing module includes a first connecting block, a first connecting joint, an arm span, a second connecting joint, a second connecting block, a rotor, a drive motor, and a hub.

[0007] The drive motor is mounted on the second connecting block, the rotor is connected to the output shaft of the drive motor, and the hub is connected to the output shaft of the drive motor.

[0008] The first connecting block and the arm span are configured to be hinged together via the first connecting joint.

[0009] The arm span and the second connecting block are configured to be rotatably connected via the second connecting joint.

[0010] The diameter of the hub is larger than the diameter of the rotor blade tip trajectory circle.

[0040] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments, not all embodiments.

[0041] Example 1

[0042] like Figure 1 and 2As shown, a multi-functional emergency rescue drone with both land and air modes includes a body module 10 and a wing module 20.

[0043] The wing module 20 adopts a switchable structure, and both walking and flying modes are achieved by using the wing module 20 for movement, which helps to reduce the overall weight.

[0044] There are four wing modules 20, which are arranged in an X-shape.

[0045] The structure of the wing module 20 will be further explained below with reference to the accompanying drawings.

[0046] like Figures 3 to 5 As shown, the wing module 20 includes a first connecting block 21, a first connecting joint 22, an arm span 23, a second connecting joint 24, a second connecting block 25, a rotor 26, a drive motor 27, and a hub 28.

[0047] Specifically, the drive motor 27 is mounted on the second connecting block 25, the rotor 26 is connected to the output shaft of the drive motor 27, and the hub 28 is connected to the output shaft of the drive motor 27.

[0048] Specifically, the first connecting block 21 and the arm span 23 are configured to be hinged together by the first connecting joint 22, and the arm span 23 and the second connecting block 25 are configured to be rotatably connected by the second connecting joint 24. The central axis of the motor's output shaft is perpendicular to the rotation axis of the arm span 23.

[0049] Specifically, the diameter of the hub 28 is larger than the diameter of the blade tip trajectory circle of the rotor 26, and the rotor 26 is located below the hub 28, which can reduce the possibility of the rotor 26 coming into contact with the ground or obstacles on the ground when walking on land.

[0050] Specifically, the first connecting block 21 is fixedly connected to the body module 10.

[0051] Specifically, the arm span 23 is hollowed out, which effectively reduces the weight of the arm span 23.

[0052] Specifically, the body module 10 has a control device (not shown), and the drive motor 27 is electrically connected to the control device.

[0053] like Figure 1 As shown, when the multi-functional emergency rescue drone in both land and air modes is in flight mode, the four wing modules 20 are in a horizontal state, while the output shaft of the drive motor 27 is perpendicular to the horizontal plane. At this time, flight can be achieved by controlling the drive motor 27 in the four wing modules 20.

[0054] like Figure 2As shown, when the multi-functional emergency rescue drone with both land and air modes changes from flight mode to walking mode, the first connecting joint rotates the arm 23 downward and makes the arm 23 perpendicular to the horizontal plane. The second connecting joint 24 rotates the second connecting block 25 to adjust the four wheel hubs 28 to be parallel to each other. At this time, walking can be achieved by controlling the drive motors 27 in the four wing modules 20.

[0055] To improve the controllability of the wing module 20, both the first connecting joint 22 and the second connecting joint 24 are electrically driven. The electrically driven joints are electrically connected to and controlled by the control device, and can change direction by controlling the second connecting joint 24 during walking.

[0056] When in use, the wing module 20 can be lowered to ground the wheel hubs, transforming it into a land-based form. The angle between the wheel hubs can be changed through the second connecting joint 24. When they are at 45° to each other, they can turn on the spot, reducing the space occupied. When the four wheel hubs are parallel to each other, they can travel quickly in a straight line, meeting the time requirements of disaster relief and reconstruction. Steering can also be controlled by controlling the speed of the drive motor 27, resulting in high overall flexibility.

[0057] Example 2

[0058] like Figure 1 and 2 As shown, this embodiment provides a multi-functional emergency rescue drone with both land and air modes. The difference between this embodiment and embodiment 1 is that it also includes a robotic arm module 30 and a solar power generation module 40.

[0059] The structure of the robotic arm module 30 will be further explained below with reference to the accompanying drawings.

[0060] like Figure 1 and 6 As shown, the robotic arm module 30 is mounted on the body module 10, and the robotic arm module 30 is equipped with a clamping device 31 and a cutting saw device 32. The wing module 20 is located above the robotic arm module 30, and the robotic arm module 30 is a four-degree-of-freedom robotic arm module 30.

[0061] The robotic arm module 30 includes a base 301, a first link 302, an upper arm 303, a second link 304, an elbow joint 305, a forearm 306, and a wrist joint 307.

[0062] The base 301 is connected to the body module and can rotate freely; the base 301 is connected to the upper arm 303 through the first link 302; the upper arm 303 and the elbow joint 305 are connected through the second link 304; the elbow joint 305 and the forearm 306 are connected to each other and can rotate; the forearm 306 and the wrist joint 307 are connected to each other and can rotate.

[0063] For example, the base 301 has an electric turntable (not shown) that enables the base 301 to rotate, and the elbow joint 305 and wrist joint 307 are both electric joints.

[0064] The sawing device 32 includes a saw blade 321 and a saw base 322. The saw base 322 is mounted on a wrist joint 307 and has a brushless motor (not shown). The output shaft of the brushless motor is fixedly connected to the saw blade 321.

[0065] The clamping device 31 is an electric clamp, which is mounted on the wrist joint 307.

[0066] The structure of the body module 10 will be further explained below with reference to the accompanying drawings.

[0067] like Figure 7 , 8 As shown in Figure 9, the body module 10 includes a camera 101, an information relay station 102, a radio 103, a sensor 104, a vacuum cleaner 105, a wastewater filter 106, a frame 107, a lower base plate 108, an upper base plate 109, an upper cover 110, and a battery (not shown).

[0068] The storage battery supplies power to all electrical appliances, and the solar power generation module 40 is installed on the upper base plate 109.

[0069] Camera 101 is installed between the lower base plate 108 and the upper base plate 109, information relay station 102 is installed on the upper base plate 109, radio 103 is installed on the upper base plate 109, infrared sensor 104 is installed on the upper base plate 109, vacuum cleaner 105 is installed on the lower base plate 108, and sewage filter 106 is installed on the lower base plate 108.

[0070] The lower base plate 108 is connected to the frame 107, the upper base plate is connected to the frame 107, the upper cover 110 is connected to the upper base plate 109, and the solar panel is connected to the upper cover 110.

[0071] To enhance its functionality, this embodiment incorporates unit components with different functions.

[0072] In land mode, the vacuum cleaner 105 always maintains a certain distance from the ground, which facilitates the cleaning of gravel and dust, and can clean up some debris on the road, thus playing a certain role in disaster area cleanup and reducing the manpower and material resources required for cleanup work.

[0073] It is equipped with a solar power generation module to charge the battery, avoiding the need for frequent recharging trips and improving efficiency.

[0074] Equipped with a wastewater treatment unit, it can purify wastewater and alleviate water shortages to some extent during emergency rescue operations in disaster areas if water supply is interrupted.

[0075] Equipped with a radio station 103 and an information relay station 102, it can still transmit communication signals normally even if communication facilities are damaged during emergency rescue.

[0076] Equipped with a camera 101 and a sensor 104, it can collect data on the situation at the rescue site in order to carry out rescue operations correctly and quickly.

[0077] The clamping device 31 can grasp objects of different sizes, and the sawing device 32 can cut large objects, such as parts of buildings, trees, and discarded furniture.

[0078] Although embodiments of this application have been shown and described above, the scope of protection of this utility model is not limited thereto. Any changes or substitutions that can be conceived without inventive effort should be included within the scope of protection of this utility model. Unless expressly stated otherwise, no element, action or instruction used herein should be construed as critical or necessary.
