As an important supporting structure for the equipment carried by UAVs, the stability and compatibility of the UAV payload frame are crucial to the performance of UAVs. At present, the common UAV payload frames on the market mostly adopt an integrated design. Although the structure is simple, the flexibility is poor and it is not easy to quickly replace or upgrade the carried equipment. In addition, the traditional payload frame needs to be redesigned and manufactured when facing different mission requirements, resulting in a long R&D cycle and high cost. Therefore, it is necessary to design a new modular payload frame for UAVs to solve the above problems. Utility Model Content

[0019] The following specific embodiments are provided to help the reader obtain a comprehensive understanding of the methods, devices and / or systems described herein. However, after understanding the disclosure of the present application, various changes, modifications and equivalents of the methods, devices and / or systems described herein will be apparent. For example, the order of operations described herein is merely an example, and is not limited to the order set forth herein, but in addition to the operations that must occur in a particular order, changes that will be apparent after understanding the disclosure of the present application may be made. In addition, in order to improve clarity and brevity, descriptions of features known in the art may be omitted.

[0020] The features described herein may be implemented in different forms and should not be interpreted as being limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0021] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0022] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0023] Although terms such as "first", "second", and "third" may be used herein to describe various components, assemblies, regions, layers, or portions, these components, assemblies, regions, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one component, component, region, layer, or portion from another component, component, region, layer, or portion. Therefore, without departing from the teachings of the examples described herein, the first component, component, region, layer, or portion referred to may also be referred to as the second component, component, region, layer, or portion.

[0024] For ease of description, spatial relative terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another element as shown in the drawings. Such spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over, an element described as being "above" or "upper" relative to another element would then be located "below" or "lower" relative to the other element.

[0025] Therefore, the term "above" includes both "above" and "below" orientations depending on the spatial orientation of the device. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative terms used herein will be interpreted accordingly.

[0026] The terms used herein are only used to describe various examples and are not used to limit the present disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms "include", "comprise" and "have" list the stated features, quantities, operations, components, elements and / or their combinations that exist, but do not exclude the existence or addition of one or more other features, quantities, operations, components, elements and / or their combinations.

[0027] Variations in the shapes shown in the drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include variations in shapes that occur during manufacturing.

[0028] The features of the examples described herein may be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, it will be apparent after understanding the disclosure of the present application that other configurations are possible.

[0029] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
