Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] See Figure 1 This illustration demonstrates the principle structure of the airframe assembly provided by this utility model. The airframe assembly 1 is a component of a multirotor aircraft and may include a frame 11 with reserved load space (not shown). Multiple weighing assemblies 12 are provided on the frame 11. Each weighing assembly 12 may include a connector 121 and a weighing component 122. It is understood that the reserved load space may be reserved space for placing or partially placing a solution tank, a spreader, or a lifting frame.

[0055] The connector 121 includes a connector body 1211 with a bearing surface 1212 and a connecting surface 1213. The bearing surface 1212 is horizontally arranged, and the connecting surface 1213 is provided with a positioning part 1214 and a connecting part 1215. The positioning part 1214 is positioned and engaged with the frame 11 to facilitate the connector 121 to be quickly positioned to the installation position. The connecting part 1215 is fixedly connected to the frame 11 to form a relatively stable connection and positional relationship between the connector 121 and the frame 11. Furthermore, the weighing component 122 includes a weighing base 1221 and a weighing part 1222 disposed on the weighing base 1221.

By using the connector 121 as a connecting intermediate between the weighing component 122 and the frame 11, it ensures that the weighing component 122 remains horizontal for weighing at various installation angles, eliminating the need for special treatment of existing weighing components or the frame. It also reduces the additional processing costs associated with creating mounting holes or cutouts on the frame 11 to accommodate different weighing component structures. Furthermore, the connector 121 also supports the installation of weighing components 122 with various configurations, providing better versatility for weighing installation and suiting scenarios requiring flexible replacement of weighing sensors.

[0057] In this invention, to reduce the impact of the weight of the connector 121 on the reduction of the multirotor's carrying capacity, multiple weight-reducing holes can be provided on the connector body.

[0058] See Figures 2 to 5 The above describes exemplary structures of the airframe assembly and multirotor provided by this utility model in various embodiments. The airframe assembly 2 includes a frame 21, which may be a frame with a square frame, and the space inside the square frame can be used as the aforementioned reserved load space.

[0059] like Figure 2As shown, the frame 21 may include a first beam 211 and a second beam 212. The second beam 212 forms a preset angle with the horizontal plane, and the first beam 211 is horizontally arranged, that is, the second beam 212 is inclined relative to the first beam 211. The first beam 211 is located at the lower end of the second beam 212. Preferably, both the first beam 211 and the second beam 212 are square tubes with hollow cavities. Accordingly, the first beam 211 includes a first top wall 2111 and a first side wall 2112; the second beam 212 includes a second top wall 2121 and a second side wall 2122, and a third side wall located opposite the second side wall 2122 (not shown in the figure, but refer to the second side wall 2122).

[0060] In this embodiment, a first weighing assembly 22 is provided on the first beam 211, and a second weighing assembly 23 is provided on the second beam 212. The connecting surface of the first weighing assembly 22 is horizontal, while the connecting surface of the second weighing assembly 23 is inclined. Figure 2 In the process, a second weighing assembly 23 is provided on each of the two inclined second beams 212, while a first weighing assembly 22 is provided on the first beam 211 at a lower position. The three weighing assemblies form three weighing sensing points for the load in a triangle. The first weighing assembly 22 is located at the middle position in the extension direction of the first beam 211, and the two second weighing assemblies 23 are both located at the end of the second beam 212 away from the first beam 211.

[0061] Specifically, such as Figure 3 As shown, the first weighing assembly 22 includes a first connector 221 and a first weighing component 222. The first connector 221 includes a first connecting body 2211, which has a first bearing surface 2212 and a first connecting surface 2213. The first connecting surface 2213 is horizontally disposed on the first top wall 2111 of the first beam 211 and is parallel to the first bearing surface 2212. The first weighing component 222 includes a first weighing seat 2221 and a first weighing part 2222 disposed thereon. The first weighing part 2222 may include a rubber sleeve for direct contact with the load.

[0062] More specifically, a first positioning insert 2214 is provided on the first connecting surface 2213 to serve as a positioning part for the first connector 221. Correspondingly, as... Figure 4As shown, a first positioning hole 2113 can be formed on the first top wall 2111. The first positioning hole 2113 is an elongated hole, and its extension direction is perpendicular to the hole axis and consistent with the extension direction of the first beam 211. The first positioning insert 2214 and the first positioning hole 2113 are connected by a plug-in engagement, which can realize the rapid positioning between the first connector 221 and the first beam 211. Furthermore, a first screw hole 2215 is formed on the first positioning insert 2214, and a second screw hole (not shown) corresponding to the first screw hole 2215 is formed on the first side wall 2112. By setting a bolt to be threadedly connected to the first screw hole 2215 and the second screw hole, a stable connection relationship can be formed between the first positioning insert 2214 and the first beam 211.

[0063] The first connector 221 is also provided with a third screw hole (not shown in the figure) extending from the first bearing surface 2212 to the first connecting surface 2213 as a connecting part of the first connector 221. Correspondingly, a fourth screw hole 2114 can be provided on the first top wall 2111. By setting a bolt to be threadedly connected to the third screw hole and the fourth screw hole 2114, the first connecting surface 2213 can be connected to the first beam 211.

[0064] like Figure 5 As shown, the second weighing assembly 23 includes a second connector 231 and a second weighing component 232. The second connector 231 includes a second connecting body 2311. The second connecting body 2311 has a second bearing surface 2312 and a second connecting surface 2313. The second connecting surface 2313 is inclinedly disposed on the top wall of the second beam 212, and the second bearing surface 2312 is horizontally disposed.

[0065] More specifically, the second connecting surface 2313 is provided with two second positioning inserts 2314 as positioning parts for the second connector 231. Correspondingly, the second top wall 2121 is provided with two second positioning holes 2123, the extension direction of the holes of the two second positioning holes 2123 being consistent with the extension direction of the second beam 212. The second positioning inserts 2314 and the second positioning holes 2123 are connected by a plug-in engagement, which enables rapid positioning between the second connector 231 and the second beam 212.

[0066] Furthermore, the two second positioning inserts 2314 are arranged in parallel, and correspondingly, the two second positioning holes 2123 are also arranged in parallel on the second top wall 2121, with the two second positioning holes 2123 respectively located on the side closest to the second side wall 2122 and the third side wall. Each of the two second positioning inserts 2314 can be provided with a screw hole, and corresponding screw holes are also provided on the second side wall 2122 and the third side wall, respectively. A bolt is provided to thread the second positioning insert 2314 on one side to the second side wall 2122, and similarly, the second positioning insert 2314 on the other side is threaded to the third side wall.

[0067] The second connector 231 is further provided with a fifth threaded hole (not shown) extending from the second bearing surface 2312 to the second connecting surface 2313 as a connecting part of the second connector 231. Correspondingly, a sixth threaded hole (not shown) may also be provided on the second top wall 2121, and a bolt is provided to be threadedly connected to the fifth threaded hole and the sixth threaded hole. This allows the second connector 231 to be threadedly connected to the second beam 212. A second weighing member 232 is provided on the second bearing surface 2312. The second weighing member 232 includes a second weighing seat 2321 and a second weighing part 2322 provided on the second weighing seat 2321.

[0068] In one implementation, such as Figure 6 As shown, combined with Figure 5 The connecting portion of the second connector 231 may include a first locking post 2315 disposed on the second connecting surface 2313, and a first locking groove 2124 disposed on the second top wall 2121. The first locking post 2315 and the first locking groove 2124 are engaged to achieve a stable connection between the second connector 231 and the second beam 212. Preferably, the first locking post 2315 and the second positioning insert 2314 are respectively disposed at different positions in the extension direction of the second connecting body 2311, wherein the extension direction of the second connecting body 2311 is consistent with the extension direction of the second beam 212.

[0069] In one embodiment, in the first weighing assembly 22 and the second weighing assembly 23, the corresponding connecting parts and weighing parts are connected by snap-fit ​​mechanisms. Taking the first weighing assembly 22 as an example:

[0070] like Figure 3As shown, in the first connector 221, a plurality of second slots 2216 can be formed on the first bearing surface 2212, and each second slot 2216 is respectively arranged along the periphery of the first bearing surface 2212. Correspondingly, in the first weighing component 222, the first weighing base 2221 is provided with a corresponding second locking post 2223, and the second slot 2216 and the second locking post 2223 engage and cooperate, thereby realizing a stable connection between the first connector 221 and the first weighing component 222. In addition, a mounting cutout 2217 is also formed on the first connector 221, which allows the wiring terminal to pass through to connect with the wiring connector on the first weighing component 222, supporting the realization of quick electrical connection of the weighing component. Preferably, the aforementioned third screw hole is formed on the first connecting body 2211 within the mounting cutout 2217. Similarly, in the second weighing assembly 23, a mounting cutout is also formed on the second connecting body 2311.

[0071] Based on the aforementioned airframe components, this utility model also provides a multirotor aircraft, which includes the aforementioned airframe components and has three weighing assemblies mounted on the frame. Using these airframe components, it is unnecessary to create corresponding mounting structures on the multirotor frame for various types of weighing components, thus reducing the component processing cost of the multirotor. Furthermore, since the connecting parts provide a horizontally positioned bearing surface, which is suitable for mounting various types of weighing components, the flexibility in selecting weighing components for the multirotor aircraft is also improved.

[0072] Finally, it should be noted that the above-described embodiments are merely specific implementations of this utility model, used to illustrate the technical solutions of this utility model, and not to limit it.
