Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle. BACKGROUND
[0002] With the rapid development of unmanned aerial vehicles, people have higher requirements for the portability of unmanned aerial vehicles. Therefore, some traditional unmanned aerial vehicles are designed with foldable arms, which are beneficial to storage and improve portability.
[0003] However, the propellers at the ends of the arms of the traditional foldable unmanned aerial vehicle are still exposed on the side of the fuselage after folding and storage, resulting in a larger width of the unmanned aerial vehicle in the storage state, lack of protection of the propellers, and a hard grip, which is not convenient for users to hold and has a poor holding feel.
[0004] The above information disclosed in the background of the present application is only used to understand the background of the concept of the present application, and can contain information which does not constitute the prior art. CONTENT OF THE UTILITY MODEL
[0005] Therefore, in view of the above problems, it is necessary to provide an unmanned aerial vehicle.
[0006] An unmanned aerial vehicle comprises:
[0007] a main body having a side wall and a top;
[0008] a plurality of arms, one end of each of the arms being rotatably connected to the main body by a rotating shaft, the other end of each of the arms being provided with a power device, the power device comprising a propeller and a motor for driving the propeller to rotate;
[0009] wherein the plurality of arms are arranged to be switchable between a folded state and an unfolded state, in the folded state, the plurality of arms and the power device are all stored in the top.
[0010] The above-mentioned unmanned aerial vehicle of the present application at least has the following beneficial effects: in the folded state, the folded plurality of arms and the power device of the unmanned aerial vehicle are all stored in the top of the unmanned aerial vehicle, which does not widen the size in the direction of the side wall of the main body, is more convenient to hold on the side wall of the main body, and the propeller of the power device is stored in the top of the main body, so that the user holding the side wall of the main body will not touch the propeller, which can avoid the deformation of the propeller when it is held and will not give the user a hard grip feeling, improving the user's experience.
[0011] In one embodiment, in the folded state, each of the power devices is accommodated between two of the arms. Such an arrangement can better protect the power devices in the folded state, and reasonably utilize the space between the arms, which is beneficial to reducing the overall size of the folded unmanned aerial vehicle.
[0012] In one of the embodiments, in the folded state, the propeller of any of the power devices does not protrude beyond the side of any of the arms away from the top. Such a structural arrangement means that the propeller in the folded state is closer to the main body, and the peripheral arm structure is more secure, that is, the propeller is not directly exposed to the outside, so as to avoid the user from touching the propeller and causing a feeling of pinching, and in the event of a collision or extrusion by an external object, the propeller will not be directly contacted by the external object, and the risk of deformation and damage of the propeller is reduced.
[0013] In one of the embodiments, in the folded state, the plurality of arms are flush away from the side of the top. Such a structure makes the overall unmanned aerial vehicle in the folded state more regular and beautiful, and is convenient to hold.
[0014] In one of the embodiments, the plurality of arms include two first arms and two second arms, and in the folded state, the two second arms are located between the two first arms, and two power devices are accommodated between any of the first arms and the adjacent second arm. Reasonable layout design utilizes the space between the first arm and the second arm to accommodate the power device, and utilizes the reduced overall size of the folded unmanned aerial vehicle to facilitate storage.
[0015] In one of the embodiments, in the folded state, any of the first arms is provided with a first limiting protrusion on the side facing the adjacent second arm, and any of the second arms is provided with a second limiting protrusion on the side facing the adjacent first arm, the first limiting protrusion is located on the side of the propeller of the power device on the second arm away from the top, and the second limiting protrusion is located on the side of the propeller of the power device on the first arm away from the top, so as to limit the movement of the propeller. In the folded state, such a structural arrangement can fix the propeller and prevent the propeller from protruding too much due to rotation.
[0016] In one of the embodiments, in the process of switching from the folded state to the unfolded state, after the two first arms are unfolded by rotating around the rotation shaft, the two second arms are unfolded by rotating around the rotation shaft, and are maintained in the unfolded state by at least one of the connection modes of clamping and magnetic attraction. In the process of switching from the unfolded state to the folded state, after the two first arms are folded to the top by rotating around the rotation shaft, the two second arms are folded to the top by rotating around the rotation shaft, and are maintained in the folded state by at least one of the connection modes of clamping and magnetic attraction.
[0017] In one of the embodiments, when switching between the folded state and the unfolded state, the line connecting any point on the motor and any point on the rotation shaft passes through a conical surface.
[0018] In one of the embodiments, the UAV further comprises a camera disposed on the main body, wherein in the unfolded state, the plurality of arms and the power device are located outside the field of view of the camera. In the unfolded state, the arms and the propellers can be hidden outside the field of view of the camera, so that the UAV does not appear in the spherical panoramic photo or video.
[0019] In one of the embodiments, the main body further comprises a bottom portion disposed opposite to the top portion, wherein the top portion and the bottom portion are each provided with at least one camera.
[0020] In one of the embodiments, the camera is disposed on the top portion of the main body, and a lens of the camera faces away from the top portion of the main body, wherein in the unfolded state, the plurality of arms and the power device are located between the lens and the top portion. In the unfolded state, the horizontal position of the arms is lower than the camera lens of the camera, so that the camera lens is not blocked and a larger field of view is obtained.

[0030] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of ways beyond the specific embodiments described and claimed herein. It is therefore intended that the present application not be limited in scope to the specific embodiments disclosed but rather that the scope of the present application be measured by the broadest permissible interpretation of the claims that follow.
[0031] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the present application provides an unmanned aerial vehicle 10, which comprises a main body 100 and a plurality of arms 200. The main body 100 has a side wall 110 and a top 120; one end of each of the arms 200 is rotatably connected to the main body 100 via a rotating shaft 300, and the other end of each of the arms 200 is provided with a power device 400, which comprises a propeller 420 and a motor 410 for driving the propeller 420 to rotate. Among them, a plurality of arms 200 are arranged to be capable of switching between a folded state and an unfolded state. For example, in the embodiments shown in Figure 1 and Figure 2 The unmanned aerial vehicle 10 has four arms 200, and in the unfolded state, the four arms 200 are unfolded, and the four power devices 400 are arranged around the main body 100 of the unmanned aerial vehicle 10, and the propeller 420 rotates to drive the main body 100 to ascend and descend. As shown in Figure 3 , Figure 4 and Figure 5 In the folded state, a plurality of arms 200 and power devices 400 are accommodated in the top 120.
[0032] The unmanned aerial vehicle 10 has at least the following advantages: in the folded state, the folded arms 200 and the power devices 400 are accommodated in the top 120 of the unmanned aerial vehicle 10, so that the size of the unmanned aerial vehicle 10 in the width direction of the side wall 110 of the main body 100 is not increased, the unmanned aerial vehicle 10 is more convenient to hold, and the propeller 420 of the power device 400 is accommodated in the top 120 of the main body 100, so that the user does not touch the propeller 420 when holding the side wall 110 of the main body 100, the propeller 420 is not deformed when being held, the user does not feel uncomfortable, and the user experience is improved.
[0033] Specifically, as shown in Figure 3 and Figure 4 in some embodiments, in the folded state, each of the power devices 400 is accommodated between two arms 200. Such an arrangement can better protect the power devices 400 in the folded state, and reasonably utilize the space between the arms 200, thereby reducing the overall size of the folded unmanned aerial vehicle 10.
[0034] More specifically, in some embodiments, in the folded state, the propeller 420 of any of the power devices 400 does not protrude beyond the side of any of the arms 200 away from the top 120. Such a structure means that the propeller 420 in the folded state is closer to the main body 100, and the peripheral arm 200 structure is more stable, that is, the propeller 420 is not directly exposed to the outside, so that the user does not feel uncomfortable when touching the propeller 420, and the propeller 420 is not directly contacted by external objects when encountering collision or external object pressing, thereby reducing the risk of deformation and damage of the propeller 420.
[0035] More specifically, as shown in Figure 3 in some embodiments, in the folded state, the sides of the plurality of arms 200 away from the top 120 are flush. Such a structure makes the overall folded unmanned aerial vehicle 10 more regular and beautiful, and is convenient to hold.
[0036] Further, as shown in Figure 3 and Figure 4 in some embodiments, the plurality of arms 200 includes two first arms 210 and two second arms 220, in the folded state, the two second arms 220 are located between the two first arms 210, and two power devices 400 are accommodated between any of the first arms 210 and the adjacent second arm 220. Reasonable layout design utilizes the space between the first arms 210 and the second arms 220 to accommodate the power devices 400, thereby reducing the overall size of the folded unmanned aerial vehicle 10 and facilitating storage.
[0037] Furthermore, such as Figure 4 As shown, in some embodiments, in the folded state, each of the first arms 210 has a first limiting protrusion 211 on the side facing the adjacent second arm 220, and each of the second arms 220 has a second limiting protrusion 222 on the side facing the adjacent first arm 210. The first limiting protrusion 211 is located on the side of the propeller 420 of the power unit 400 on the second arm 220 facing away from the top 120, and the second limiting protrusion 222 is located on the side of the propeller 420 of the power unit 400 on the first arm 210 facing away from the top 120, to restrict the movement of the propeller 420. In the folded state, this structural arrangement can fix the propeller 420 and prevent the propeller 420 from protruding too much due to rotation.
[0038] In some embodiments, during the transition from the folded state to the unfolded state, after the two first arms 210 rotate and unfold around the pivot 300, the two second arms 220 then rotate and unfold around the pivot 300, and are maintained in the unfolded state by at least one of the connection methods of snap-fit and magnetic connection; during the transition from the unfolded state to the folded state, after the two first arms 210 rotate and fold around the pivot 300 to the top 120, the two second arms 220 then rotate and fold around the pivot 300 to the top 120, and are maintained in the folded state by at least one of the connection methods of snap-fit and magnetic connection.
[0039] In some embodiments, when switching between the folded state and the unfolded state, the surface traced by the line connecting any point on the motor 410 and any point on the rotating shaft 300 is a conical surface.
[0040] Please see Figure 5 and Figure 6 In some embodiments, the drone 10 further includes a camera device 500 disposed on the main body 100. For example... Figure 6 As shown, in the deployed state, the multiple arms 200 and the power unit 400 are all located outside the field of view of the camera device 500. The deployed arms 200 and propellers 420 can be hidden outside the field of view of the camera device 500, ensuring that the drone 10 will not be visible when capturing spherical panoramic photos or videos.
[0041] Specifically, such as Figure 5 As shown, in some embodiments, the main body 100 further includes a bottom 130 disposed opposite to the top 120, and both the top 120 and the bottom 130 are provided with at least one of the camera devices 500.
[0042] Specifically, as shown in Figure 6 In some embodiments, the camera 500 is arranged on the top 120 of the main body 100, and the lens 510 of the camera 500 faces away from the top 120 of the main body 100. The lens 510 can be a fisheye lens 510 or the like. In the unfolded state, the plurality of arms 200 and the power device 400 are located between the lens 510 and the top 120. In the unfolded state, the horizontal position of the arm 200 is lower than the camera of the camera 500, so that the camera is not blocked and a larger field of view is obtained.
