In other instances, well known process steps have not been described in detail in order to avoid unnecessarily obscuring the present application. Therefore, the specific embodiments described herein are not intended to be limiting, but rather are to serve as examples for the practicing the present application.
[0018] It is to be understood that when an element is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element or intervening elements can also be present. In addition, it should be understood that when an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements can also be present. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0020] As Figures 1-2As shown, a UAV with a tilt angle arm includes a body 1 and a plurality of arms 2, one end of the plurality of arms 2 is connected with the body 1, the other end of the arm 2 is provided with a rotor 3, and the included angle between the arm 2 and the body 1 is 15-25 degrees. Specifically, in this embodiment, the body 1 is streamlined, which can reduce the flight wind resistance, the plurality of arms 2 are arranged around the body 1, the end of the arm 2 away from the body 1 is used for installing the rotor 3, the motor (not shown in the figure) is installed on the arm 2, which is used to drive the rotor 3 to rotate to obtain the lifting force, that is, the UAV can fly. The arm 2 is connected with the body 1, and the included angle between the arm 2 and the body 1 is specifically 15-25 degrees. Let the machine be horizontal to the ground in actual flight, reduce the energy consumption, and have the structure design of the hidden antenna, avoid designing the antenna outside the body 1, thereby reducing the flight wind resistance, so that the machine has longer flight endurance.
[0021] Specifically, in this embodiment, the number of the arm 2 is four.
[0022] Specifically, in this embodiment, the rotor 3 is three-leafed.
[0023] Specifically, in this embodiment, the included angle between the arm 2 and the body 1 is 20 degrees.
[0024] As shown, Figure 3 The front end of the body 1 is provided with a camera 4, the camera 4 is connected with the body 1 through a silica gel ball 5, the camera 4 is isolated from the body 1 through the silica gel ball 5, so that the part of the frequency vibration of the body 1 is isolated from the camera 4, thereby solving the jelly effect during camera shooting, that is, avoiding the object in the photographed image to be distorted or inclined.
[0025] Specifically, the body 1 is provided with a battery pack, and a fireproof switch is arranged on the output line of the battery pack, so as to avoid the battery pack directly powering other components, direct power-on is easy to cause fire, and the fire will greatly reduce the service life of the plug and cause great safety hazards, therefore, the fireproof switch is used for isolation.
[0026] Specifically, the battery pack is further provided with an electric quantity display lamp, which is used for displaying the electric quantity of the battery pack, without the need of inserting an electric quantity measuring device to measure the electric quantity of the battery pack or inserting the battery pack into a charger to obtain the electric quantity, and the use is more intuitive.
[0027] As shown, Figure 3As shown in the drawings, the upper end of the body 1 is provided with a flow guide plate 6, the lower surface of the flow guide plate 6 is a flat surface, the upper surface of the flow guide plate 6 is an arc surface, and a gap exists between the lower surface of the flow guide plate 6 and the body 1. Specifically, because the lower surface of the flow guide plate 6 is flat, the gas flow speed passing below the flow guide plate 6 is slow, according to Bernoulli's principle, the place where the flow speed is greater, the pressure is smaller, therefore the pressure on the arc-shaped upper surface of the flow guide plate 6 is relatively small, and the pressure difference exists between the upper and lower surfaces of the flow guide plate 6, so that the flow guide plate 6 is subjected to an upward pressure difference, obtains lift, and further increases the flight stability of the unmanned aerial vehicle.
[0028] As shown in the drawings, Figure 3 The body 1 directly opposite to the flow guide plate 6 is hollow, the body 1 is provided with various electronic components, a large amount of heat is generated when the unmanned aerial vehicle is in flight, and the hot gas can be discharged through the hollow part to realize air cooling and heat dissipation.
