Description

Technical Field

[0001] The present application relates to the technical field of unmanned aerial vehicles, and in particular to a unmanned aerial vehicle. Background Art

[0002] Drones have a large application market and can perform high-altitude operations such as transportation, reconnaissance or signal transmission.

[0003] In the prior art, a drone comprises a body, an arm and a propeller. The arm is mounted on the body, and the propeller is mounted on the arm. The propeller generates lift for the drone to take off through its own rotational motion.

[0004] However, in the prior art, the propeller of the drone will generate vibrations with a certain frequency range during its rotational motion. When the frequency range of the propeller's vibrations intersects with the resonance frequency of the drone's own structure, the drone's own structure will resonate, which increases the difficulty of controlling the drone's flight. Summary of the invention

[0005] The present application provides a drone, which has a lower possibility of resonance, making the flight control of the drone less difficult.

[0006] The present application provides a drone, which includes a body and an attachment, wherein the attachment is connected to the body, wherein the rigidity of the attachment is less than or greater than the rigidity of the body.

[0007] The drone of the present application includes a body and an attachment connected to the body, wherein the stiffness of the attachment is different from the stiffness of the body, so that the stiffness of the assembly composed of the body and the attachment is neither the same as the stiffness of the body nor the same as the stiffness of the attachment. Among them, the resonant frequency of the structure is related to the stiffness of the structure. The greater the stiffness, the greater the resonant frequency. Correspondingly, the smaller the stiffness, the smaller the resonant frequency. The present application can set an attachment with a stiffness smaller than the stiffness of the body on the body, or set an attachment with a stiffness larger than the stiffness of the body on the body, so that the assembly composed of the body and the attachment has a new resonant frequency. Under the condition that the stiffness of the body is the same, by adjusting the stiffness of the attachment, the assembly composed of the body and the attachment has a resonant frequency of different sizes. When the resonant frequency of the assembly composed of the body and the attachment is adjusted to outside the vibration frequency range of the propeller of the drone, it is difficult for the body to resonate due to the vibration of the propeller of the drone, thereby reducing the difficulty of controlling the flight of the drone. Furthermore, since the adjustable range of the stiffness of the attached parts is relatively large, the adjustable range of the resonant frequency of the assembly consisting of the body and the attached parts is also relatively large, and the resonant frequency of the assembly consisting of the body and the attached parts can be adjusted to outside the vibration frequency range of various propellers, that is, it has a high degree of adjustability.

[0054] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0055] It should be clear that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0056] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0057] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0058] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0059] For background technical questions, please refer to Figure 1 As shown, the present application embodiment provides a drone 10. Please refer to Figure 2 As shown, the drone 10 includes a body 1 and an attachment 2 , wherein the attachment 2 is connected to the body 1 , wherein the rigidity of the attachment 2 is less than or greater than the rigidity of the body 1 .

[0060] In the present application, please refer to Figure 2 As shown, the drone 10 includes a body 1 and an attachment 2 connected to the body 1, wherein the stiffness of the attachment 2 is different from the stiffness of the body 1, so that the stiffness of the assembly consisting of the body 1 and the attachment 2 is neither the same as the stiffness of the body 1 nor the same as the stiffness of the attachment 2. Among them, the resonant frequency of the structure is related to the stiffness of the structure. The greater the stiffness, the greater the resonant frequency. Correspondingly, the smaller the stiffness, the smaller the resonant frequency. In the embodiment of the present application, an attachment 2 with a stiffness smaller than that of the body 1 can be set on the body 1, or an attachment 2 with a stiffness larger than that of the body 1 can be set on the body 1, so that the assembly consisting of the body 1 and the attachment 2 has a new resonant frequency. Under the condition that the stiffness of the body 1 is the same, by adjusting the stiffness of the attachment 2, the assembly consisting of the body 1 and the attachment 2 has different resonance frequencies. When the resonant frequency of the assembly consisting of the body 1 and the attachment 2 is adjusted to a range outside the vibration frequency of the propeller (not shown) of the drone 10, the body 1 is unlikely to resonate due to the vibration of the propeller of the drone 10, thereby reducing the difficulty of controlling the flight of the drone 10. Furthermore, since the adjustable range of the stiffness of the attachment 2 is relatively large, the adjustable range of the resonant frequency of the assembly consisting of the body 1 and the attachment 2 is relatively large, and the resonant frequency of the assembly consisting of the body 1 and the attachment 2 can be adjusted to a range outside the vibration frequency of various propellers, that is, it has a high degree of adjustability.

[0061] Among them, the embodiment of the present application is not limited to the stiffness of the body 1, nor is it limited to the stiffness of the accessory 2, nor is it limited to the difference between the stiffness of the accessory 2 and the stiffness of the body 1. The user can set the stiffness of the body 1 and the stiffness of the accessory 2 according to the frequency of the propeller of the drone 10.

[0062] In addition, the stiffness of the accessory 2 is related to the material, shape, structure, and size of the accessory 2 itself. Under the condition that the stiffness of the body 1 is the same, the user can adjust the stiffness and corresponding resonance frequency of the assembly consisting of the body 1 and the accessory 2 by installing different types of accessories 2 on the body 1.

[0063] The subsequent content of this article mainly describes the case where the stiffness of the accessory 2 is greater than the stiffness of the body 1. For example, the material of the accessory 2 can be metal, and the material of the body 1 can be non-metallic (such as carbon fiber).

[0076] Optionally, see Figure 4 As shown, the first portion 21 is provided with a first through hole 211, please refer to Figure 3 As shown, the box body 11 includes a first protrusion 113 protruding from the first body 111 into the box body 11, and the first protrusion 113 is arranged in the first through hole 211. Under this arrangement, the first protrusion 113 can play a role of fixing the first part 21 to improve the connection reliability between the box body 11 and the first part 21; secondly, the first protrusion 113 plays a role of positioning the first part 21 to limit the movement of the first part 21 relative to the box body 11.

Under this setting, the attachment 2 can play an electromagnetic protection role for the antenna 3, reduce the degree of interference to the signal of the antenna 3, that is, reduce the degree of delay in signal transmission, so that the user can control the drone in time to improve the safety of the drone flight process. On the other hand, the embodiment of the present application uses the attachment 2 as part of the grounding circuit of the antenna 3, and there is no need to set up other parts separately as the grounding circuit of the antenna 3.
