Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) component technology, specifically to a UAV support frame and a UAV. Background Technology

[0002] To achieve lightweighting of drones and reduce their overall weight, injection-molded drone load-bearing frame structures have been developed. These structures consist of a plastic frame body and bolt inserts, allowing for extensive use of plastic and significantly reducing weight. However, the following problems have been identified in the production of these plastic drone frame structures: 1. Conventional bolt inserts embedded in plastic parts will fall off after repeated use; 2. Due to the gap between the bolt inserts and the mold ejector pins, there is displacement during injection molding; 3. During use, the vibration load generated by the peripheral connecting parts of the load-bearing frame structure is large, causing cracks to appear at the threaded connections of the plastic frame.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] like Figures 1 to 3 As shown, this utility model embodiment provides a drone support frame 10, including a plastic frame body 100 for accommodating the drone host and a metal insert frame 200 for connecting to the propeller arm. The plastic frame body 100 includes a top frame 110 and a frame 120, and the metal insert frame 200 includes a connecting frame 210 and a plurality of mounting seats 220 disposed circumferentially and evenly distributed on the connecting frame 210. One side of the top frame 110 is provided with multiple first interlocking structures, and one side of the connecting frame 210 is provided with multiple second interlocking structures. The top frame 110 and the connecting frame 210 are stacked, and multiple first interlocking structures are interlocked with multiple second interlocking structures in a one-to-one correspondence.

[0026] The UAV support frame 10 provided by this utility model has a specific configuration of plastic frame body 100 and metal insert frame 200, which allows them to be injection molded together during production. The two are interlocked to achieve a stable connection. Compared with the existing UAV support frame 10, the connecting bolts and four independent mounting seats are eliminated, which not only enhances the connection strength between plastic frame body 100 and metal insert frame 200, but also reduces the number of parts, and can better ensure installation accuracy and improve design reliability.

[0027] Mounting bracket 220 is used to connect the propeller arm. Its specific structure is matched according to the actual target propeller arm structure, which will not be described in detail here.

[0028] Preferably, to further improve the structural connection stability, the plastic frame body is integrally molded, and the metal insert frame is integrally molded.

[0030] Specifically, such as Figures 4 to 6As shown in the illustrated embodiment of this utility model, the inner annular frame 111 is circular, and the outer annular frame 112 is square. The inner annular frame 111 is connected to one side of the outer annular frame 112 by every three first connecting posts 113. It should be noted that the specific structure of the top frame 110 can be adapted to the actual UAV structure and is not limited to the structure shown in the illustrations of this application. The inner annular frame 111 is not limited to a circular ring, and the outer annular frame 112 is not limited to a square ring.

[0031] Furthermore, such as Figure 7 and Figure 8 As shown, the thickness of each mounting base 220 is greater than that of the second connecting post 212. With the thickness direction of the mounting base 220 as the vertical direction, each second connecting post 212 is connected to the connecting ring 211 at one end in the horizontal direction and to the mounting base 220 at the other end. The bottom surface of the mounting base 220 is flush with the second connecting post 212, and the top surface of the mounting base 220 is higher than the second connecting post 212, so that multiple mounting bases 220 form a mounting window 230 on multiple second connecting posts 212. The top frame 110 is embedded in the mounting window 230, and the top surface of the top frame 110 is flush with the top surface of the mounting base 220. Each mounting base 220 is located outside the plastic frame body 100.

Any interlocking structure that can improve the stability of the connection between the plastic frame body 100 and the metal insert frame 200 is acceptable.

[0036] Furthermore, in order to further improve the stability of the connection between the plastic frame body 100 and the metal insert frame 200, the cross-sectional shape of the protrusion 221 in the transverse direction is arrow-shaped.

[0037] It should be noted that in other embodiments of this utility model, the shape of the protrusion 221 can also be toothed, trapezoidal, or irregular mushroom-shaped.

[0038] Optionally, each first interlocking structure is an interlocking groove or an interlocking protrusion; when the first interlocking structure is an interlocking groove, the second interlocking structure corresponding to the first interlocking structure is an interlocking protrusion that fits perfectly into the interlocking groove; when the first interlocking structure is an interlocking protrusion, the second interlocking structure corresponding to the first interlocking structure is an interlocking groove that fits perfectly into the interlocking protrusion.

[0039] Furthermore, in order to further improve the stability of the connection, the embedding groove includes a first embedding groove 216 and a second embedding groove 115; the interlocking protrusion includes a first interlocking protrusion 215 and a second interlocking protrusion 116.

The middle one of the three second connecting posts 212 has a plurality of first interlocking protrusions 215 evenly arranged on the side facing the top frame 110 along the length of the second connecting post 212. The two side two of the three second connecting posts 212 have strip-shaped first embedding grooves 216 arranged on the side facing the top frame 110 along the length of the second connecting post 212. The first inserting protrusion 215 has a connecting end 215a and a free end 215b, the connecting end 215a is connected to the second connecting post 212, and the size of the free end 215b is larger than the size of the connecting end 215a; the first embedding groove 216 has a groove opening 216a and a groove bottom 216b, and the size of the groove opening 216a is smaller than the size of the groove bottom 216b. A portion of the multiple first connecting posts 113 are provided with multiple second embedding grooves 115 that cooperate with the first embedding protrusion 215 to allow the first embedding protrusion 215 to be fully embedded; a portion of the multiple second connecting posts 212 are provided with strip-shaped first embedding grooves 216 that cooperate with the strip-shaped second embedding protrusions 116 in the first embedding grooves 216.

[0040] To further improve the stability of the connection, the first embedding groove 216 of each strip extends all the way to the surface of the connecting ring 211, and the corresponding second embedding protrusion 116 also extends all the way to the surface of the annular inner frame 111.

[0041] It should be noted that the specific arrangement of the above-described interlocking protrusion and embedding groove is only one embodiment of this utility model, and the positions of the interlocking protrusion and the corresponding embedding groove can be interchanged. Furthermore, the specific structure of the interlocking protrusion and embedding groove is not limited to the structure shown in the figure. As long as the size of the interlocking protrusion at the bottom of the embedding groove is larger, the stability of the connection between the plastic frame body and the metal insert frame can be effectively improved.
