A core of the present application is to provide a fully protected drone, to improve the operation security and the portability of the drone.
It should be noted that, terms such as “first”, “second” and the like in the present application are only intended to distinguish multiple components or structures having the same or similar structures from each other, rather than define particular arrangement order or connection relationship.
In the present application, the directions “up”, “down”, “left” and “right” are defined with reference to a drone body 1. The direction in which the drone faces the ground in a using state is defined as “down”, and the direction opposite to “down” is defined as “up”; and the direction in which the drone body 1 extends is defined as the “front and rear direction”, and in a plane parallel to the drone body 1, the direction perpendicular to the front and rear direction is the “left and right direction”.
A drone according to the present application is described in detail hereinafter in conjunction with drawings, to help those skilled in the art to accurately understand the technical solutions of the present application.
As shown in
With the above structure, the rotary wing 2 is internally mounted in the protection housing 3, an operator will not directly contact the rotary wing 2, and can fly and retrieve the drone by hand, and thus a landing gear in the conventional technology is omitted, which improves the operation convenience. During the operation, the operator does not contact the rotary wing 2, which avoids the human body from being injured by the rotary wing 2 spinning at a high speed, thereby improving the operation security. The protection housing 3 is configured to have a meshed structure, and the hollow area provides an adequate space for the rotary wing 2 to generate a lift force, while meeting the requirement for griping, thereby ensuring the normal flight of the drone. The protection housing 3 is configured to have a closed housing structure which has no sharp corner and will not have a sharp tip which may cause injury to the human body, and the operator may hold any portions of the protection housing 3, thereby further improving the security and convenience in holding the drone. The rotary wing 2 is internally mounted in the protection housing 3 and is connected to the drone body 1 through the protection housing 3. Compared with the conventional technology in which the rotary wing 2 is connected above the drone body 1 through a connecting rod, the structure, in which the rotary wing 2 is internally mounted, reduces an overall height of the drone, thereby improving the portability of the drone.
The protection housing 3 may have various structures, as described above, as long as the protection housing 3 can satisfy the installation requirement of the rotary wing 2 and has a certain hollow rate. For example, the protection housing 3 may be configured as a quadrate hollow housing, or to have other forms such as circular shape, triangular shape, trapezoid and the like.
As shown in
In the above structure, the top plate 32 and the bottom plate 33 are equivalent to a top cover and a bottom cover of the middle frame 34, and the middle frame 34 constitutes a body structure of the protection housing 3. In detail, the middle frame 34 may be configured in the form of U shape and specifically in the form of U shape when being viewed from the top. The open end of the U shape directly faces the drone body 1, and the middle frame 34 is connected to the drone body 1 through the open end of the U shape. As shown in
In the above protection housing 3, the top plate 32 and the bottom plate 33 may be directly fixedly mounted onto the middle frame 34 and then connected to the drone body 1 through the middle frame 34. The top plate 32 and the bottom plate 33 may be connected to the middle frame 34 in a detachable manner, such as threaded connection and the like, and may also be fixedly connected to the middle frame 34 in a fixed manner, such as welding and the like. The top plate 32 and the bottom plate 33 may also be directly connected to the drone body 1 rather than via the middle frame 34. In the embodiment shown in
Specifically, the rotary wing 2 may be mounted on the top plate 32 or the bottom plate 33, and in an arrangement manner, the rotary wing 2 may be mounted on the top plate 32. As shown in
In the embodiment shown in
The mounting portions 321 may be arranged according to the number of the rotary wings 2 and the distribution of the rotary wings 2. For example, by taking an extending direction of the drone body 1 as the front and rear direction, several of the mounting portions 321 may be arranged at intervals on the top plate 32 from front to rear. Since the middle frame 34 is connected to the drone body 1 through its open end, the arrangement of the mounting portions 321 at intervals from front to rear is the arrangement of the mounting portions 321 at intervals in a direction from one side to another side of the middle frame 34. The intervals between the individual mounting portions 321 may be equal or different. The position of individual mounting portion 321 can be adjusted by those skilled in the art according to the installation requirement of the rotary wings 2.
As described above, the connection between the middle frame 34 and the drone body 1, the connection between the top plate 32 and the middle frame 34, and the connection between the bottom plate 33 and the middle frame 34 may each be achieved in a detachable manner. The detachable connection refers to the connection that can be detached as required without damaging the connector, such as threaded connection, pin connection and the like.
In addition, in the present application, each of the top plate 32, the bottom plate 33 and the middle frame 34 may be configured as an integrated structure or may be configured as a separated structure that can be spliced together. In detail, the top plate 32 may include several first sub-plates, and the first sub-plates may be spliced to form a plate-like integrated part that can match with the drone body 1 and the middle frame 34. Similarly, the bottom plate 33 may also include several first sub-plates, and the several first sub-plates are spliced to form an integrated plate-like structure and may be specifically arranged with reference to the top plate 32.
The middle frame 34 may include two side plates 341 and an end plate 342 connected at tail ends of the two side plates 341. A head end of each of the side plates 341 is connected to the drone body 1, and the tail end of the side plate 341 refers to an end opposite to the head end. Meanwhile, each of the side plates 341 may include second sub-plates configured to be spliced together, the end plate 342 may also include second sub-plates configured to be spliced together, and the second sub-plates can be spliced as required to form a desired structure of the middle frame 34.
With the above structural form that can be spliced, the protection housing 3 according to the present application can be adjusted as required, for example by adjusting the length and width of the top plate 32, the length and width of the bottom plate 33, the length, width and height of the middle frame 34, the structural form of the top plate 32, the bottom plate 33 and the middle frame 34 and the like. In this way, the protection housing 3 can match with the drone body 1, to mount four rotary wings 2 or other numbers of rotary wings 2, thereby effectively extending the application range of the protection housing 3 and improving the convenience in assembling and disassembling the protection housing 3.
The top plate 32, the bottom plate 33 and the middle frame 34 may also be configured as a foldable structure or other portable structures as desired.
On this basis, reference is further made to
In more detail, the meshed structure of the protection housing 3 may be a regular hexagonal grid pattern mesh, as shown in
Moreover, in the present application, the meshed structure may be made of a carbon fiber plate, that is, the protection housing 3 may be made of a carbon fiber plate. In this case, the drone has a light weight, and thus can better meet the flight requirement in the case that the rotary wing 2 has a certain power loss.
For the drone of the present application, two sides of the drone body 1 may be each provided with the protection housing 3, and the protection housings 3 at the two sides of the drone body 1 may be symmetrically arranged in the left and right direction with respect to the drone body 1, such as the drone with four rotary wings 2 as shown in
