Description

Technical Field

[0001] This utility model relates to the field of aircraft parts technology, and in particular to a thrust motor mounting structure and an aircraft having the same. Background Technology

[0002] With the development of aviation technology, airplanes are receiving increasing attention. On an airplane, the thrust motor drives the propeller at the tail, providing the propulsion for forward flight. During flight, the thrust motor, mounted on the fuselage structure, primarily generates torsional and compressive loads, and considering changes in aircraft attitude, it also generates yaw moments. Therefore, the strength and rigidity requirements for the thrust motor mounting structure in an airplane are relatively high.

[0003] Improving the strength and rigidity of the thrust motor mounting structure has become a pressing issue for manufacturers and research institutions. Utility Model Content

[0004] This utility model provides a thrust motor mounting structure and an aircraft having the same. The thrust motor mounting structure has reliable connection and high strength and rigidity.

[0005] This utility model provides a thrust motor mounting structure, including a motor body, a motor mounting base, and an aircraft frame structure. The motor body is fixed to one end face of the motor mounting base, and the other end face of the motor mounting base opposite to the motor body is fixed to the frame structure.

[0006] Furthermore, the skeleton structure includes a crossbeam and a stringer, the crossbeam being configured to extend along the width direction of the aircraft and the stringer being configured to extend along the length direction of the aircraft.

[0007] Furthermore, the thrust motor mounting structure also includes a skin that covers the outside of the stringer, and the end of the skin covers part of the motor mounting base.

[0008] Furthermore, the motor mounting base includes a connecting plate and a fixing plate. The connecting plate is in the shape of a hollow column and extends along the length of the stringer. The fixing plate is disposed on one end of the connecting plate facing the crossbeam and the stringer. The crossbeam and the stringer are fixed to the fixing plate. The motor body is fixed to the end of the connecting plate away from the fixing plate.

[0009] Furthermore, the end of the connecting plate facing the motor body is folded outward to form a plurality of motor connecting ears, and the motor body is fixed to the connecting plate through the motor connecting ears.

[0010] Furthermore, a hollow section is formed in the middle of the fixing plate, so that the fixing plate has an edge fixing plate located at the edge and a middle fixing plate spanning the hollow section. Both ends of the middle fixing plate are connected to the edge fixing plate. The stringer is fixedly connected to the edge fixing plate, and the crossbeam is fixedly connected to the middle fixing plate.

[0011] Furthermore, there are multiple stringers, and the ends of the multiple stringers facing the motor mounting base are connected to the edge fixing plate at intervals.

[0012] Furthermore, the thrust motor mounting structure also includes a skin, which consists of multiple pieces, each piece of which is fixed between the two stringers.

[0013] Furthermore, the end of the stringer is fixed to the edge fixing plate via a stringer joint. At the end of the stringer, the skin, the stringer, and the stringer joint are fixed together by fasteners, and the end of the skin is fixed to the connecting plate by fasteners.

[0014] This utility model also provides an aircraft, including the aforementioned thrust motor mounting structure.

[0015] In summary, in this invention, the motor body is fixed to one end face of the motor mounting base, and the other opposite end face of the motor mounting base is fixed to the aircraft's frame structure. That is, the motor mounting base is fixed between the frame structure and the motor body. When the motor body starts, the reaction force of the motor body can be transmitted laterally to the frame structure through the motor mounting base, and longitudinally to the fuselage through the frame structure. This structure allows the surrounding aircraft structure to bear the reaction force of the motor body; therefore, the connection of this motor mounting structure is reliable and possesses high strength and rigidity. Furthermore, in this thrust motor mounting structure, the motor body is essentially located at the rear of the aircraft along its length, allowing it to be directly exposed to the air, which is more conducive to heat dissipation.

[0024] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0027] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0028] This utility model provides a thrust motor mounting structure and an aircraft having the same. The thrust motor mounting structure has reliable connection and high strength and rigidity.

[0029] Please refer to Figures 1 to 4 The thrust motor mounting structure provided in this embodiment includes a motor body 10, a motor mounting base 20, and an aircraft frame structure 30. The motor body 10 is fixed to one end face of the motor mounting base 20, and the other end face of the motor mounting base 20 opposite to the motor body 10 is fixed to the frame structure 30.

[0030] In this embodiment, the motor body 10 is fixed to one end face of the motor mounting base 20, and the other opposite end face of the motor mounting base 20 is fixed to the aircraft frame structure 30. That is, the motor mounting base 20 is fixed between the frame structure 30 and the motor body 10. When the motor body 10 starts, the reaction force of the motor body 10 can be transmitted laterally to the frame structure 30 through the motor mounting base 20, and the reaction force of the motor body 10 can be transmitted longitudinally to the fuselage through the frame structure 30. The above structure enables the aircraft structure around the motor mounting base 20 to bear the reaction force of the motor body 10. Therefore, the connection of the motor mounting structure is relatively reliable and has high strength and rigidity. At the same time, in this thrust motor mounting structure, along the length direction of the aircraft, the motor body 10 is actually located at the rear end of the aircraft and outside the skin of the aircraft motor arm. This allows the motor body 10 to be directly exposed to the air, which is more conducive to heat dissipation.

[0031] Furthermore, in this embodiment, as Figure 2 As shown, heat dissipation fins are formed on the outer side wall of the motor body 10. Since the motor body 10 is located at the rear of the aircraft and exposed to the air, the heat dissipation fins further facilitate heat dissipation of the motor body 10.

[0032] like Figures 2 to 4As shown, in this embodiment, the frame structure 30 includes a tail beam 31 and a stringer 32 for the motor arm. The beam 31 is configured to extend along the width direction of the aircraft, and the stringer 32 is configured to extend along the length direction of the aircraft. Both the beam 31 and the stringer 32 are fixed to the end of the motor mounting base 20 away from the motor body 10.

[0033] Please continue to refer to Figure 5 In this invention, the motor mounting base 20 includes a connecting plate 21 and a fixing plate 22. The connecting plate 21 is a hollow column and extends along the length of the stringer 32. Preferably, the connecting plate 21 is cylindrical. The fixing plate 22 is disposed on the end of the connecting plate 21 facing the crossbeam 31 and the stringer 32. The crossbeam 31 and the stringer 32 are fixed to the fixing plate 22, and the motor body 10 is fixed to the end of the connecting plate 21 away from the fixing plate 22.

[0034] Furthermore, to facilitate the fixing of the motor body 10, the end of the connecting plate 21 facing the motor body 10 is folded outward to form a plurality of motor connecting ears 211. The motor body 10 is fixed to the connecting plate 21 via the motor connecting ears 211. The circumferential arrangement of multiple motor connection ears 211 can improve damage tolerance. When one motor connection ear 211 is damaged, there are still many other motor connection ears 211 to ensure the stability of the connection.

[0035] In this embodiment, a cutout is formed in the middle of the fixing plate 22, so that the fixing plate 22 forms an edge fixing plate 221 located at the edge and a middle fixing plate 222 spanning the cutout. Both ends of the middle fixing plate 222 are connected to the edge fixing plate 221. Preferably, the edge fixing plate 221 is annular.

[0036] The aforementioned hollow structure design reduces the weight of the mounting base, thereby reducing the overall weight of the aircraft. Furthermore, it provides space for the connection of the crossbeam 31 and the stringer 32. Additionally, it facilitates the arrangement of the wiring harness between the motor body 10 and the aircraft.

[0037] Please continue to refer to Figure 4 In this embodiment, one end of the stringer 32 facing the motor mounting base 20 is connected to the edge fixing plate 221. There can be multiple stringers 32, which are spaced apart and connected to the fixing plate 22. Preferably, the edge fixing plate 221 is connected to the stringer 32. One end of the crossbeam 31 facing the motor mounting base 20 is fixed to the central fixing plate 222. Please continue reading Figures 1 to 3 and Figure 6In this embodiment, the thrust motor mounting structure further includes a skin 40, which covers the outside of the stringers 32. The end of the skin 40 covers a portion of the motor mounting base 20, specifically a portion of the connecting plate 21, so that a portion of the connecting plate 21 and the motor body 10 are exposed outside the skin 40. The skin 40 can also consist of multiple pieces, each skin 40 fixed between two stringers 32.

[0038] A through hole (not shown) is provided on the skin 40 for the crossbeam 31 to pass through, and the crossbeam 31 is connected to the motor mounting base 20 after passing through the through hole.

[0039] The end of the stringer 32 can be fixed to the edge fixing plate 221 via the stringer joint 321. The skin 40 can be glued to the stringer 32. At the end of the stringer 32, that is, the end of the stringer 32 facing the motor mounting base 20, the skin 40, stringer 32, and stringer joint 321 can be fixed together by fasteners, such as bolts. The end of the skin 40 is fixed to the connecting plate 21 by fasteners, such as bolts.

[0040] In summary, in this invention, the motor body 10 is fixed to one end face of the motor mounting base 20, and the other opposite end face of the motor mounting base 20 is fixed to the frame structure 30. That is, the motor mounting base 20 is fixed between the frame structure 30 and the motor body 10. When the motor body 10 starts, the reaction force of the motor body 10 can be transmitted laterally to the frame structure 30 through the motor mounting base 20, and longitudinally to the fuselage through the frame structure 30. This structure allows the surrounding aircraft structure to bear the reaction force of the motor body 10. Therefore, the connection of this motor mounting structure is relatively reliable and possesses high strength and rigidity. Furthermore, in this thrust motor mounting structure, the motor body 10 is essentially located at the end of the aircraft along its length, allowing it to be directly exposed to the air, which is more conducive to heat dissipation.
