Description

Technical Field

[0001] This invention relates to a drone device, and more particularly to a drone turning device. Background Technology

[0002] The all-electric turning mechanism is typically mounted on the nose landing gear of the UAV, installed on the extended lug of the buffer strut, and engages with the buffer sleeve for power transmission. The all-electric turning mechanism operates during UAV takeoff and landing, primarily for autonomous entry and exit and heading adjustment during low-speed taxiing on the ground. During takeoff and landing, the nose landing gear is in its lowered position, exposing the turning mechanism to the air. It may face complex and variable environmental conditions such as rain, snow, dust, sand, and obstacles, thus requiring a high level of protection. Furthermore, the all-electric turning mechanism typically includes various electrical components, each connected by wiring harnesses. These components are structurally dispersed, resulting in exposed wiring and cables that not only offer poor protection but also create unsightly installation issues due to the messy wiring. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a drone turning device with a high level of protection, a more convenient installation process, and greater safety.

[0004] To address the aforementioned technical problems, this application provides the following technical solution:

[0005] This invention discloses a turning device for a drone, comprising a motor, a clutch, a reducer, an angle sensor, an electrical connector, an output gear, a first protective cover, and a second protective cover. The motor is connected to a motor wiring harness, the clutch is connected to a clutch wiring harness, and the angle sensor is connected to an angle sensor wiring harness. The motor wiring harness, the clutch wiring harness, and the angle sensor wiring harness are all connected to the electrical connector. The first protective cover is fitted over the motor, the clutch, the reducer, the angle sensor, the motor wiring harness, the clutch wiring harness, and the angle sensor wiring harness. The second protective cover is fitted over the output gear, and a power transmission interface is provided on the second protective cover.

[0006] Furthermore, the first protective cover includes a first receptacle and a second receptacle that are internally interconnected. The first receptacle is fitted over the angle sensor, the motor wiring harness, the clutch wiring harness, and the angle sensor wiring harness. The second receptacle is fitted over the motor, the clutch, and the reducer. The first end of the first receptacle is provided with a first mounting hole corresponding to the electrical connector. The electrical connector is located outside the first mounting hole. The electrical connector is provided with a mounting end cap, which is connected to the first mounting hole. The second end of the first receptacle is connected to the second protective cover.

[0007] Furthermore, the reducer housing is provided with a first lug and a second lug. The reducer housing is provided with a first protruding ridge, a second protruding ridge, and a third protruding ridge connected in sequence on the outer edges of the first lug and the second lug. The first protruding ridge and the third protruding ridge both extend along the axial direction of the reducer. The second protruding ridge extends along the outer circumferential surface of the reducer housing. The second protruding ridge is located on the side away from the output gear. The first end of the second housing is a closed end. The second end of the second housing forms a notch at the position corresponding to the first lug and the second lug. The first edge, the second edge, and the third edge of the notch abut against the first protruding ridge, the second protruding ridge, and the third protruding ridge, respectively. The remaining part of the second end of the second housing is connected to the second protective cover.

[0008] Furthermore, it also includes a mounting plate, which comprises a first mounting plate unit and a second mounting plate unit connected to each other. The first mounting plate unit is disposed around the angle sensor. An external connection port is formed on the housing of the reducer between the first lug and the second lug. The second mounting plate unit is disposed around the housing of the reducer except for the external connection port. The mounting plate is connected to the second protective cover. The plane of the mounting plate is perpendicular to the axial direction of the first and second accommodating bodies. The second end of the first accommodating body is connected to the first mounting plate unit, and the second end of the second accommodating body is connected to the second mounting plate unit.

[0009] Furthermore, it also includes a first connector and a second connector. The second end of the second housing is provided with a first connecting hole, the second edge is provided with a second connecting hole, the second mounting plate unit is provided with a third connecting hole, and the second protruding ridge is provided with a fourth connecting hole. The first connecting hole and the third connecting hole correspond one-to-one, and the second connecting hole and the fourth connecting hole correspond one-to-one. One first connector passes through one first connecting hole and one third connecting hole, and one second connector passes through one second connecting hole and one fourth connecting hole to connect the second housing to the second protective cover.

[0010] Furthermore, it also includes multiple third connectors. Multiple fifth connector holes are evenly distributed at the second end of the first container. The second protective cover and the first mounting plate unit are both provided with sixth connector holes. The fifth connector holes and the sixth connector holes correspond one-to-one. One of the third connectors passes through one of the fifth connector holes and one of the sixth connector holes to connect the first container to the second protective cover.

[0011] Furthermore, the second container is provided with a protrusion extending along the length direction, the protrusion being used to accommodate the motor wiring harness.

[0012] Furthermore, the first connector, the second connector, and the third connector are all screws.

[0013] Furthermore, the second protective cover includes interconnected cover bodies and end caps.

[0014] Furthermore, the motor, the clutch, the reducer, the angle sensor, the electrical connector, the output gear, the first protective cover, and the second protective cover are all made of steel.

[0015] Compared with the prior art, the UAV turning device of the present invention has at least the following beneficial effects:

[0016] This invention discloses a drone turning device. Because the first protective cover covers the motor, clutch, reducer, angle sensor, motor wiring harness, clutch wiring harness, and angle sensor wiring harness, and the second protective cover covers the output gear, all components of the drone turning device, except for the power transmission interface and electrical connector, are enclosed within the protective covers. This significantly improves the protection level of the drone turning device, enabling it to adapt to complex and changing harsh environments. Furthermore, because the motor wiring harness, clutch wiring harness, and angle sensor wiring harness are scattered, and all fourteen wires need to be connected to electrical interfaces, the cables become messy, posing safety hazards during installation. By housing the motor wiring harness, clutch wiring harness, and angle sensor wiring harness within the first protective cover, not only is the protection level improved, but the installation process is also more convenient and safer.

[0017] The drone turning device of the present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention discloses a turning device for a drone, comprising a motor 01, a clutch 02, a reducer 03, an angle sensor 04, an electrical connector 05, an output gear 06, a first protective cover 07, and a second protective cover 08. The motor 01 is connected to a motor wiring harness 11, the clutch 02 is connected to a clutch wiring harness 21, and the angle sensor 04 is connected to an angle sensor wiring harness 41. The motor wiring harness 11, the clutch wiring harness 21, and the angle sensor wiring harness 41 are all connected to the electrical connector 05. The first protective cover 07 is fitted over the motor 01, clutch 02, reducer 03, angle sensor 04, motor wiring harness 11, clutch wiring harness 21, and angle sensor wiring harness 41. The second protective cover 08 is fitted over the output gear 06. The second protective cover 08 is provided with a power transmission interface 83, at which the output gear 06 meshes with a buffer rotating gear. Motor harness 11 is typically a three-core winding harness and a six-core resolver harness, clutch harness 21 is typically a two-core harness, and angle sensor harness 41 is typically a three-core harness. Motor harness 11, clutch harness 21, and angle sensor harness 41 use electrical connector 05 as their external electrical interface. The UAV turning device of this invention features a first protective cover 07 covering the motor 01, clutch 02, reducer 03, angle sensor 04, motor wiring harness 11, clutch wiring harness 21, and angle sensor wiring harness 41, and a second protective cover 08 covering the output gear 06. All components of the entire UAV turning device, except for the power transmission interface 83 and electrical connector 05, are enclosed within these protective covers, significantly improving the protection level of the UAV turning device and enabling it to adapt to complex and challenging environments. Furthermore, the previously scattered arrangement of the motor wiring harness 11, clutch wiring harness 21, and angle sensor wiring harness 41, with all fourteen wires requiring connection to electrical interfaces, resulted in messy cabling and potential safety hazards during installation. The inclusion of the motor wiring harness 11, clutch wiring harness 21, and angle sensor wiring harness 41 within the first protective cover 07 not only improves the protection level but also makes installation more convenient and safer.

[0026] Furthermore, such as Figure 3 , Figure 4 , Figure 5As shown, the first protective cover 07 includes a first receiving body 71 and a second receiving body 72 that are internally interconnected. The first receiving body 71 is fitted over the angle sensor 04, motor wiring harness 11, clutch wiring harness 21, and angle sensor wiring harness 41. The second receiving body 72 is fitted over the motor 01, clutch 02, and reducer 03. The first end of the first receiving body 71 is provided with a first mounting hole 73 corresponding to the electrical connector 05. The electrical connector 05 is located outside the first mounting hole 73 and is provided with a mounting end cap 51. The mounting end cap 51 is located at the first mounting hole 73 and is connected to the hole wall of the first mounting hole 73. The second end of the first receiving body 71 is connected to the second protective cover 08. Specifically, the mounting end cap 51 is connected to the hole wall of the first mounting hole 73 by multiple bolts.

[0027] Furthermore, such as Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, the housing of the reducer 03 is provided with a first lug 31 and a second lug 32. The first lug 31 and the second lug 32 are external mounting interfaces for the turning device and are fixedly connected to the extended lugs of the landing gear buffer strut. The housing of the reducer 03 is provided with a first protruding rib 33, a second protruding rib 34, and a third protruding rib 35 connected in sequence on the outer edge of the first lug 31 and the second lug 32. The first protruding rib 33 and the third protruding rib 35 both extend along the axial direction of the reducer 03, and the second protruding rib 34 extends along the outer circumferential surface of the housing of the reducer 03. The second protruding rib 34 is located on the side away from the output gear 06. The first end of the second receiving body 72 is a closed end, which is fitted onto the motor 01. The second end of the second receiving body 72 forms a notch 721 at the position corresponding to the first lug 31 and the second lug 32. The first edge 7211, the second edge 7212, and the third edge 7213 of the notch 721 abut against the first protruding rib 33, the second protruding rib 34, and the third protruding rib 35, respectively. The remaining part of the second end of the second receiving body 72 is connected to the second protective cover 08. By setting the first protruding rib 33, the second protruding rib 34, and the third protruding rib 35, the first edge 7211, the second edge 7212, and the third edge 7213 of the notch 721 abut against the first protruding rib 33, the second protruding rib 34, and the third protruding rib 35, respectively, so that the first protective cover 07 forms a closed protective space, further improving the protection level.

[0028] Furthermore, such as Figure 6 , Figure 7As shown, it also includes a mounting plate 09, which comprises a first mounting plate unit and a second mounting plate unit connected to each other. The first mounting plate unit is disposed around the angle sensor 04. An external connection port is formed on the housing of the reducer 03 between the first lug 31 and the second lug 32. The second mounting plate unit is disposed around the remaining portion of the housing of the reducer 03, excluding the external connection port. The mounting plate 09 is connected to the second protective cover 08. The plane of the mounting plate 09 is perpendicular to the axial direction of the first housing 71 and the second housing 72. The second end of the first housing 71 is connected to the first mounting plate unit, and the second end of the second housing 72 is connected to the second mounting plate unit. By providing the mounting plate 09, the installation of the first housing 71 and the second housing 72 is facilitated. Furthermore, since the mounting plate 09 is connected to the second protective cover 08, it further ensures that a closed protective space can be formed after the first protective cover 07 is installed, thereby further improving the protection level.

[0029] Furthermore, such as Figure 5 , Figure 6 , Figure 7 As shown, it also includes a first connector and a second connector. The second end of the second housing 72 is provided with a plurality of first connecting holes 723, the second edge 7212 is provided with a second connecting hole 7214, the second mounting plate unit is provided with a plurality of third connecting holes 91, and the second protrusion 34 is provided with a fourth connecting hole 341. The first connecting holes 723 and the third connecting holes 91 correspond one-to-one, and the second connecting holes 7214 and the fourth connecting holes 341 correspond one-to-one. A first connector passes through a first connecting hole 723 and a third connecting hole 91 respectively, and a second connector passes through a second connecting hole 7214 and a fourth connecting hole 341 respectively to connect the second housing 72 to the second protective cover 08.

[0030] Furthermore, it also includes multiple third connectors. Multiple fifth connector holes 711 are evenly distributed at the second end of the first housing 71. The second protective cover 08 and the first mounting plate unit are both provided with sixth connector holes 92. The fifth connector holes 711 and the sixth connector holes 92 correspond one-to-one. A third connector passes through a fifth connector hole 711 and a sixth connector hole 92 respectively to connect the first housing 71 and the second protective cover 08.

[0031] Furthermore, the second housing 72 is provided with a protrusion 724 extending along its length, which is used to accommodate the motor wiring harness 11. Since the motor wiring harness 11 has a large number of cables, accommodating the motor wiring harness 11 in the protrusion 724 reduces the size of the remaining parts of the second housing 72, making the second housing 72 fit more closely with the motor 01, clutch 02, and reducer 03, and making it easier to form a closed protective space.

[0032] Furthermore, the first, second, and third connecting parts are all screws, such as... Figure 3 As shown, screw 94 passes through a fifth connecting hole 711 and a sixth connecting hole 92. The screw serves as a connector, making disassembly and reassembly easier.

[0033] Furthermore, the second protective cover 08 includes an interconnected cover body 81 and an end cap 82, which facilitates disassembly.

[0034] Furthermore, the motor 01, clutch 02, reducer 03, output gear 06, first protective cover 07, and second protective cover 08 are all made of steel, which simplifies the manufacturing process and greatly reduces the need for subsequent sandblasting and painting protection procedures.

[0035] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
