Description

Technical Field

[0001] The utility model relates to an unmanned flight device, in particular to an unmanned flight device with an optical module. Background Art

[0002] With the more refined semiconductor process technology, the performance of electronic photosensitive elements has been improved, and the pixel can reach a smaller size. Therefore, an optical lens with high imaging quality has become an indispensable part. In addition, with the rapid development of technology, the application range of mobile phone devices equipped with optical lenses is more extensive, and the requirements for optical lenses are also more diverse.

[0003] Generally speaking, existing unmanned aerial vehicles usually configure multiple motors to drive blades with different rotation directions respectively. Specifically, the motor and the rotating blade can be arranged in pairs, and these motors are respectively used to drive a rotating blade. One motor is used to drive the corresponding rotating blade to rotate clockwise, and the other motor is used to drive the corresponding rotating blade to rotate counterclockwise, so as to keep the unmanned aerial vehicle balanced during flight. Through the above configuration, the rotation speed of each motor can be adjusted, so that the unmanned aerial vehicle can perform various flight actions such as forward, backward, sideward, upward, downward and rotation. However, because existing unmanned aerial vehicles are configured with multiple motors, the overall weight of the unmanned aerial vehicle cannot be reduced, thus affecting the flight speed and sensitivity of the unmanned aerial vehicle.

[0083] The detailed features and advantages of the present utility model are described in detail in the embodiments below. The content is sufficient for any person skilled in the relevant art to understand the technical content of the present utility model and implement it accordingly. And according to the content recorded in this specification, the scope of the patent application and the drawings, any person skilled in the relevant art can easily understand the relevant objectives and advantages of the present utility model. The following embodiments further illustrate the viewpoints of the present utility model in detail, but do not limit the scope of the present utility model in any way.

[0084] The present utility model provides an unmanned flight device, which includes a body, a coaxial contra-rotating motor, a steering assembly, and an optical module.

[0085] The body has a first end and a second end that are opposite to each other. Wherein, along the direction extending from the first end to the second end, a central axis passing through the body is defined. The central axis passing through the body may refer to a virtual straight line that penetrates the body and extends along the direction from the first end towards the second end, and the central axis may, for example, pass through the structural center or geometric center of the body, but the present utility model is not limited thereto.

[0086] The coaxial contra-rotating motor is disposed at the first end of the body, and the coaxial contra-rotating motor includes a forward rotating blade and a reverse rotating blade. The common rotating shaft of the forward rotating blade and the reverse rotating blade coincides with the central axis, and the rotating direction of the forward rotating blade is opposite to the rotating direction of the reverse rotating blade.

[0087] The steering assembly includes a steering base and at least one flow guiding wing. The steering base is rotatably connected to the body along the circumferential direction of the central axis, and at least one of the flow guiding wings is connected to the steering base and is used to guide the flow direction of air.

[0088] The optical module is disposed on other components in the unmanned flight device. For example, the optical module may be disposed on the body, the coaxial contra-rotating motor, or the steering assembly, but the present utility model is not limited thereto.

[0089] According to the unmanned flight device described in the present utility model, by adopting the configuration of the coaxial contra-rotating motor, the problem that the unmanned flight device cannot control the balance due to the single-direction torque generated on the body by the unidirectional rotation of the blades can be overcome. And this configuration does not require using multiple motors to separately drive the forward and reverse blades. Only a single motor (i.e., the coaxial contra-rotating motor) can be used to drive the unmanned flight device and maintain balance during flight. In addition, since the unmanned flight device is only equipped with a single motor, the overall weight can be reduced, which helps to improve the flight speed of the unmanned flight device. Additionally, the steering assembly has the configuration of the flow guiding wing, and the position of the flow guiding wing can be adjusted by rotating around the central axis, so that the movement of the unmanned flight device in the horizontal direction or the vertical direction can be adjusted. And the steering assembly can simultaneously have the functions of flying and staying in the air and steering.

[0090] In one embodiment, the unmanned flying device further includes a wing assembly, and the wing assembly is symmetrically arranged on the body about the central axis. Thus, the wing assembly can provide the function of staying in the air during flight. Among them, in the embodiment where the unmanned flying device includes a wing assembly, the optical module can be arranged on the wing assembly. It should be noted that the wing assembly can be optional. In some embodiments of the present invention, the unmanned flying device may not have a wing assembly.

[0091] In one embodiment, the steering assembly is arranged at the second end of the body. Among them, the steering base of the steering assembly is rotatably connected to the second end along the circumferential direction of the central axis. Thus, by arranging the coaxial counter-rotating motor and the steering assembly along the central axis (that is, the coaxial counter-rotating motor and the steering assembly are respectively arranged at the first end and the second end of the body), the overall weight of the unmanned flying device can be concentrated on the central axis, which helps to be stable and not easy to deviate during flight, and there is no need to additionally adjust the problem of the torque deviation of the rotor blades.

[0092] The optical module can be arranged on the body. Thus, it helps to fix the shooting angle of the optical module.

[0093] The optical module can be arranged on the steering base of the steering assembly, and the steering base is made of a light-transmitting material; thus, the steering base made of a light-transmitting material enables the steering assembly to cooperate with the optical module to have optical value. In the embodiment where the steering base is made of a light-transmitting material and the optical module is arranged on the steering base, the optical module has an optical axis, and the optical axis can intersect with the central axis; thus, the outermost object-side lens in the optical module can form a relatively arc-shaped surface together with the steering assembly, thereby reducing wind resistance. The outermost object-side lens can refer to the lens closest to the object to be photographed in the lens group of the optical module.

[0094] The radial length of the body can gradually decrease from the second end to the first end. Thus, by making the radial length of the body gradually decrease towards the tail end of the unmanned flying device, the unmanned flying device can reduce the tail turbulence during flight to reduce wind resistance.

[0095] The unmanned flying device of the present invention can further include an induction motor. The induction motor can be arranged on the body, and the induction motor can be located on the central axis and be controllably connected to the steering assembly to drive the steering assembly to rotate relative to the body. Thus, by arranging the motor for controlling the steering assembly on the central axis, the overall weight of the unmanned flying device can be balanced. The induction motor is controllably connected to the steering assembly, which can mean that the connection manner between the induction motor and the steering assembly enables the induction motor to control and drive the rotation of the steering assembly. It should be noted that the induction motor can be optional. In some embodiments of the present invention, the unmanned flying device may not have an induction motor.

[0096] The induction motor may have a rotatable steering shaft member, and the steering base may be connected to the steering shaft member. The induction motor is used to drive the steering base to rotate relative to the body through the steering shaft member, and the axis line of the steering shaft member may be parallel to and located on the central axis. Thus, the torque generated by the induction motor is concentrated on the central axis, which can prevent the torque generated when the induction motor rotates from destroying the balance and causing jitter.

[0097] The steering base may include a connecting portion and a head portion. The connecting portion is rotatably connected to the steering shaft member relative to the body. The head portion is connected to the connecting portion and extends away from the steering shaft member along the direction of the central axis. And the head portion has an arc surface on the side away from the connecting portion. Thus, the resistance of the windward surface can be reduced through the configuration of the arc surface to increase the flight speed of the unmanned flight device.

[0098] Define the position where the arc surface of the head portion of the steering base intersects the central axis as a vertex. Among them, the angle between a plane passing through the vertex and tangent to the arc surface and the central axis is θ, which can satisfy the following conditions: 50°≤θ≤90°. Thus, the shape of the head portion is rounder and can have optical value. Among them, the following conditions can also be satisfied: 70°≤θ≤90°. Please refer to Figure 4 , which shows a schematic diagram of the parameter θ in the first embodiment of the present invention. In an implementation manner of the present invention, the optical module may be disposed at the head end of the steering assembly, and the head portion may be integrally formed with the outermost lens of the optical module.

[0099] At least one of the guide vanes may include two guide vanes, and the two guide vanes are symmetrically arranged about the central axis on the steering base. Thus, by arranging the guide vanes symmetrically about the central axis, the overall weight of the unmanned flight device can be balanced.

[0100] Each of the two guide vanes may have a windward side facing the head portion of the steering base and a leeward side relatively farther from the head portion than the windward side. The steering assembly may further include two auxiliary wings, and the two auxiliary wings may be respectively disposed on the leeward sides of the two guide vanes. Thus, by arranging the auxiliary wings to finely control the air flow, the effect of finely controlling the flight direction of the unmanned flight device can be achieved. It should be noted that the auxiliary wings are optional. In some implementation manners of the present invention, the steering assembly may not have auxiliary wings.

[0101] In one embodiment, the optical axis of the optical module coincides with the central axis; thus, by arranging the optical module on the central axis, the overall weight balance of the unmanned flying device is achieved, and it is not easy to cause an imbalance problem. Among them, when the optical module is arranged at the head end of the steering assembly (that is, at the edge of the head of the steering base), the object-side curvature of the outermost lens of the optical module can be combined with the arc surface of the head of the steering base, so that the arc surface facing the wind of the head is more in line with the flow direction of the air fluid, thereby reducing the resistance of the unmanned flying device during flight. The optical module is arranged at the head end of the steering assembly, and reference can be made to the corresponding Figure 20 embodiment.

[0102] In one embodiment, the optical module is arranged at the head of the steering base, where the optical axis intersects the central axis, and an acute angle is formed between the optical axis and the central axis. Thus, by arranging the optical module at a position other than the top of the head, the viewing angle of the optical module can be adjusted as the steering assembly rotates. The optical module is arranged at a position other than the top of the head, and reference can be made to the corresponding Figure 15 embodiment and the corresponding Figure 25 embodiment.

[0103] Each technical feature in the unmanned flying device described in the above-mentioned present invention can be combined and configured to achieve the corresponding effects.

[0104] According to the above embodiments, specific embodiments are proposed below and will be described in detail with reference to the accompanying drawings.

Specifically, the steering assembly 14 includes a steering base 141, two flow guiding wings 142, and two ailerons 143. Among them, the steering base 141 is connected to the steering shaft member 130 of the induction motor 13, and the induction motor 13 is used to drive the steering base 141 to rotate relative to the body 10 through the steering shaft member 130, so that the steering base 141 is rotatably connected to the second end portion 102 of the body 10 along the circumferential direction of the central axis CL through the steering shaft member 130. Further, the steering base 141 includes a connecting portion 1411 and a head portion 1412. The connecting portion 1411 is rotatably connected to the steering shaft member 130 relative to the body 10. The head portion 1412 is connected to the connecting portion 1411 and extends away from the steering shaft member 130 along the direction of the central axis CL from the connecting portion 1411, and the head portion 1412 has a curved surface CS1 on the side away from the connecting portion 1411.

[0113] The two flow guiding wings 142 are symmetrically connected to the connecting portion 1411 of the steering base 141 with respect to the central axis CL and are used to guide the flow direction of air. Each of the two flow guiding wings 142 has a windward side WS1 facing the head 1412 of the steering base 141 and a leeward side WS2 that is relatively farther away from the head 1412 than the windward side WS1. The two ailerons 143 are respectively arranged on the leeward sides WS2 of the two flow guiding wings 142.
