[0025] The present application is described in detail below in conjunction with specific embodiments. It should be emphasized that the following description is merely illustrative and is not intended to limit the scope of the present application and its application.

[0027] Figure 1 Schematic diagram of the unmanned aerial vehicle frame provided in the embodiment of the present application. Figure 1 As shown, the unmanned aerial vehicle includes: a lens protection structure 10 , a body 20 and at least one lens 30 .

[0028] The lens protection structure 10 is a structural component that can be switched between two different states. In the present application, the terms "first state" and "second state" are used to represent it.

[0029] Specifically, the first state refers to the position where the lens protection structure 10 at least partially covers the lens 30. Figure 2 As shown, the lens protection structure not only protects the lens 30, but also forms a protruding foot for supporting the body 20. The second state refers to the position where the lens protection structure 10 is not covering or shielding the lens 30.

[0030] The above-mentioned “not covered and blocked” means that the lens protection structure 10 is outside the FOV of the lens 30 and will not affect the image captured by the lens 30. The field of view (FOV) refers to the range of the image that can be captured by the lens. It can usually be measured in angles, indicating the visible range from the center point of the lens to the outermost side.

[0031] The fuselage 20 is the main body of the unmanned aerial vehicle, which is mainly composed of a fuselage shell forming the outer contour of the fuselage and functional modules (such as a flight control system and a battery module) contained in the inner space of the fuselage shell or functional modules hung outside the fuselage shell.

[0032] Specifically, the unmanned aerial vehicle may further include an arm 40 and a rotor mechanism 50. The arm 40 is a component extending outward from the fuselage 10. A suitable number of the arm 40 may be provided. For example, 4 are shown in the figure. The rotor mechanism 50 is a component for providing flight power. The rotor mechanism 50 may be assembled and fixed at the end of the arm.

[0033] The fuselage 20 can be set to any suitable size and shape according to the actual needs, and is not specifically limited here. For example, it is shown in a square form in the drawings of the present application specification.

[0034] Specifically, Figure 2 As shown, the generally rectangular body 20 can be described as having a length direction X, a width direction Y, and a thickness direction Z.

[0035] In this embodiment, the two ends of the body 20 that are away from each other in the length direction are referred to as the “third end” and the “fourth end”. The two surfaces of the body 20 that are away from each other in the thickness direction can be referred to as the “third surface” and the “fourth surface”.

[0036] Among them, the "third surface" can be defined as the part of the UAV facing or close to the ground when it is on the ground and during landing, and it can also be called the "bottom of the fuselage."

[0037] The connecting portion 13 of the lens protection structure 10 is correspondingly connected to the third end of the fuselage, and cooperates to form a rotation axis X1 parallel to the width direction of the fuselage 20. Therefore, the structural body 11 of the lens protection structure 10 can rotate around the rotation axis X1 under the action of a motor or other similar power output device, thereby switching between the first state and the second state.

[0038] The lens 30 is disposed on the fuselage 20 and is an optical device part for collecting image information. In order to have a wider field of view and shooting angle, the lens 30 can be designed to protrude from the surface of the fuselage 10. Specifically, at least one lens 30 is located on the third surface of the fuselage and protrudes from the third surface to collect image information located below the fuselage of the unmanned aerial vehicle.

[0039] In some embodiments, according to actual needs, for example, when shooting 360° panoramic image information from top to bottom, the lens 30 can also be set to two, respectively set on the third surface and the fourth surface, for collecting and covering different perspectives, so as to finally stitch together the panoramic image information.

[0040] In actual use, Figure 3 As shown, when in a state of preparing for landing, the lens protection structure 10 can be in a first state, covering the lens 30 to protect the lens 30 while forming an extended support leg 12 to serve as a landing gear to support the fuselage.

[0041] like Figure 4 As shown, when in a normal flight state, the lens protection structure 10 is in a second state, located outside the FOV of the lens 30, and will not interfere with or block the shooting image of the lens 30, thereby ensuring smooth flight shooting.

[0042] In some embodiments, Figure 2 As shown, the lens protection structure 10 includes: a structural body 11, a supporting portion 12 and a connecting portion 13.

[0043] The structural body 11 is a structural component used to cover and mask the lens. A storage space for accommodating the lens is formed inside the structural body 11. The lens can enter or leave the storage space through the opening end of the structural body 11 as the position of the structural body 11 changes.

[0044] In this embodiment, the structural body may be relatively flat. For ease of description, its two surfaces facing each other are respectively referred to as a first surface and a second surface. The open end of the structural body 11 is disposed on the first surface.

[0045] The support part 12 is a structural component used to form the support leg of the unmanned aerial vehicle. It can be set to a corresponding shape and size according to the needs of the actual situation to meet the use needs of the unmanned aerial vehicle for the landing gear.

[0046] In this embodiment, the support portion 12 extends from the second surface of the structural body to a certain distance away from the structural body to achieve the above-mentioned support function. In other words, the support portion 12 and the opening ends of the structural body 11 are located on two surfaces away from each other.

[0047] The connecting part 13 is a connecting component used to establish a rotational connection between the lens protection structure 10 and the fuselage of the unmanned aerial vehicle. It can be assembled on the fuselage 20 so that the structural body 11 has the freedom to flip relative to the fuselage 20.

[0048] In this embodiment, the term "assembly" is used to indicate the rotational connection relationship between the connection portion 13 and the fuselage 20. It should be noted that the rotational connection relationship only indicates the rotational freedom between the two components, and does not limit the specific connection structure between the two components. The specific connection structure design can be selected according to the actual needs.

[0049] For example, the rotational connection between the connection portion 13 of the lens protection structure and the body 20 can be a non-detachable connection structure design to provide sufficient structural strength. Alternatively, the rotational connection between the connection portion 13 of the lens protection structure and the body 20 can also be a detachable connection structure design to facilitate the replacement of structural components.

[0050] At least one advantageous aspect of the unmanned aerial vehicle frame provided by the embodiment of the utility model is that by respectively arranging an open end and a support portion on both sides of the structural body of the lens protection structure, the structural body can be flipped over to cover and protect the lens while a protruding support foot is formed by the support portion, thereby providing the unmanned aerial vehicle with a function similar to a landing gear.

[0051] In some embodiments, the structural body 11 may be designed as a component extending a certain length along the axial direction, and its two ends away from each other in the axial direction may be respectively referred to as a “first end” and a “second end”.

[0052] The support portion 12 and the connection portion 13 are both arranged at the first end. Therefore, the protruding support portion 12 can also be used as an angle limiting mechanism to limit and fix the flipping of the structural body 11.

[0053] Specifically, the support portion 12 may be a pair of legs 121. The pair of legs 121 are symmetrically arranged along the axis direction and are located on both sides of the structural body in the axis direction.

[0054] In some embodiments, the structural body 11 can be roughly divided into two parts: an arc-shaped protruding portion 111 and a frame portion 112 .

[0055] The arc-shaped protrusion 111 is an arc structure with one end open and protruding in a direction away from the opening. Its open end can form the open end of the structural body 11, and the above-mentioned accommodation space is formed inside. The specific protruding curvature and size of the arc-shaped protrusion 111 can be determined according to the actual lens to be protected and shielded, and are not specifically limited here.

[0056] The frame portion 112 is the outer edge portion surrounding the arc-shaped raised portion 111. It can have a suitable edge width and thickness to provide sufficient mechanical structural strength. The connecting portion 13 and the supporting portion 12 are both fixedly arranged at the position where the frame portion 112 is located.

[0057] Specifically, Figure 3 and Figure 4 As shown, the rotation of the structural body 11 of the lens protection structure 10 can only be performed within a certain angle range. In the present application, the angle range is described by "first limit angle" and "second limit angle", which correspond to the first state and the second state of the lens protection structure respectively.

[0058] The "first limit angle" refers to the situation where the structural body 11 of the lens protection structure 10 rotates to the point where the first surface contacts the third surface of the body 20. At this time, due to the restriction of the third surface of the body 20, the structural body 11 of the lens protection structure 10 cannot continue to rotate further in the same direction and is in the first state.

[0059] like Figure 2 and Figure 3 As shown, in the first state, the lens 30 protruding from the third surface enters the receiving space of the lens protection structure through the opening end, that is, it is covered by the lens protection structure. At the same time, the support part 12 can also form a support structure for the unmanned aerial vehicle on the ground and during take-off and landing, playing the role of bearing the weight of the fuselage and preventing the fuselage from directly contacting the ground.

[0060] The "second limit angle" refers to the situation where the main body 11 of the lens protection structure 10 rotates to the point where the support portion 12 abuts against the third end of the fuselage body. At this time, due to the abutment restriction between the support portion 12 and the fuselage body 20, the main body 11 of the lens protection structure 10 cannot continue to rotate further in the same direction and is in the second state.

[0061] Specifically, the support portion 12 may also be formed with an abutment surface 122 of suitable size and shape to achieve mutual abutment with the fuselage 20. For example, the abutment surface 122 may be designed to have a shape that matches the fuselage 20 so that the two have a tight concave-convex fit when abutting.

[0062] like Figure 4 As shown, in the second state, the lens protection structure 10 and the lens 30 are located on completely different surfaces of the body, outside the FOV of the lens 30 , and will not cause any impact on the picture taken by the lens 30 .

[0063] Preferably, an additional locking assembly may be provided between the support portion 12 and the third end of the fuselage 20 to help fix the position of the lens protection structure 10 to prevent it from flipping over during normal flight of the UAV and causing the lens to be covered.

[0064] The locking assembly can specifically use any suitable type of mechanism with a limiting function, including but not limited to: a magnetic locking assembly based on magnetic adsorption, a combination of male / female fasteners based on snap-on connection, and a cam spring shaft locking mechanism composed of a cam spring shaft.

[0065] In some embodiments, in order to ensure that the support portion has sufficient supporting capacity during the take-off and landing of the unmanned aerial vehicle and to avoid unexpected movement of the lens protection mechanism, the unmanned aerial vehicle may further include a locking mechanism.

[0066] The locking mechanism is disposed on the third surface of the fuselage, and is used to lock the position of the lens protection structure when the first surface of the lens protection structure is in contact with the third surface of the fuselage, thereby ensuring that the lens protection mechanism 10 can withstand a large impact force and maintain a fixed position during the take-off and landing of the unmanned aerial vehicle.

[0067] Specifically, the locking mechanism can also adopt any suitable type of fixed connection components according to the actual needs, including but not limited to a magnetic locking assembly based on magnetic adsorption, a combination of male / female fasteners based on snap-on connection, and a cam spring shaft locking mechanism composed of a cam spring shaft.

[0068] For example, taking the above-mentioned "cam spring shaft locking mechanism" as an example, the specific working process of the locking mechanism is as follows:

[0069] The cam can be cylindrical or disc-shaped, with one or more raised parts on its surface, called cam peaks. The spring is an elastic element connected between the cam and the shaft, which can provide a certain amount of pressure and elasticity to maintain contact between the cam and the shaft.

[0070] As the cam turns, the cam peak interacts with the groove in the shaft, preventing the shaft from rotating freely. The pressure of the spring keeps the cam peak in close contact with the groove or hole, effectively locking the shaft in place.

[0071] Therefore, by reasonably setting the position of the cam peak and the matching groove on the shaft, the cam peak can enter the matching groove when the lens protection structure 10 is rotated to the first limit angle, thereby limiting the rotation by locking the position of the shaft.

[0072] Preferably, when using a magnetic locking assembly based on magnetic adsorption, the characteristics of the electromagnet can be utilized to enable the locking mechanism to have the ability to be triggered and controlled by an electrical signal, thereby being able to decide whether to trigger the locking function of the locking mechanism according to different usage scenarios.

[0073] The present application also provides an unmanned aerial vehicle, which includes the above-mentioned unmanned aerial vehicle and further includes a corresponding control panel, a camera module, a battery, etc.

[0074] It should be noted that one or more structural components disclosed in the above embodiments can be omitted or added according to the actual needs to provide corresponding functions or technical effects. The above structural components are not mutually exclusive or related and can be used in any combination to form multiple different embodiments.

[0075] The above contents are further detailed descriptions of the present application in combination with specific / preferred implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the scope of protection of the present application.
