The central body 11 may serve as a central reference for the frame 10. With the central body 11 as the center, a plurality of horn are distributed on the periphery of the central body 11. In particular, in this embodiment, the multi-rotor unmanned aerial vehicle is a four-rotor unmanned aerial vehicle.

The forward rotor 20 and the reverse rotor 30 are provided on the frame 10. The forward rotors 20 and the reverse rotors 30 are alternately fixed to the end of the horn remote from the central body 11. The forward and reverse rotors 20 and 30 may provide flight power for the multi-rotor unmanned aerial vehicle. The number of the positive rotation rotors 20 is the same as that of the negative rotation rotors 30, so that the force of the machine frame 10 is balanced and the machine frame keeps stable and parallel. The forward and reverse rotors 20 and 30 adjust the rotational speed of the propellers to cause the multi-rotor unmanned aerial vehicle to ascend, descend, advance, retreat, turn left, turn right, and the like.

The forward rotor 20 and the reverse rotor 30 each include a motor, a propeller, and an elastic member. The power supply is arranged on the frame and is electrically connected with the power supply. The power supply provides power to the motor. The power source may be a rechargeable lithium battery or the like. The power supply can be a plurality of, and a plurality of power supplies can be dismantled and locate in the frame.

Referring to fig. 7 and 8, the forward rotary wing 20 includes a first motor 21, a first propeller 22, and a first elastic element 23. The counter rotor 30 includes a second motor 31, a second propeller 32, and a second elastic member 33. The first motor 21 and the second motor 31 are disposed on the frame and electrically connected to a power supply. The first motor 21 and the second motor 31 have similar structures, but the first motor 21 is a forward rotation motor, and the second motor 31 is a reverse rotation motor. The first propeller 22 is similar in structure to the second propeller 32, except that the first propeller 22 is a forward rotating propeller and the second propeller 32 is a reverse rotating propeller. The first motor 21 drives the first propeller 22 to rotate clockwise, and the second motor 22 drives the second propeller 32 to rotate counterclockwise. Now, the first motor 21 and the first propeller 22 are described as an example, and the second motor 31 and the second propeller 32 are not described again.

Referring to fig. 2, the first motor 21 includes a stator (not shown), a rotor (not shown), a rotating end 211 and a centering shaft 212. The stator and the rotor rotate relatively. The rotating end 211 rotates about the rotation axis of the first propeller 22. The centering shaft 212 is located at the center of the rotating end 211, and the axial direction of the centering shaft 212 is located on the same axis as the rotating shaft. The centering shaft 212 is used for driving the first propeller 22 to rotate. The first propeller 22 includes a propeller base 221 and blades 222. Two of the paddles 222 are respectively provided with two ends of the paddle base 221. The paddle mount 221 is open with a slit 229 for mounting the paddle 222. The blade 222 is accommodated in the gap 229, and the blade 222 and the paddle holder 221 are fixed by bolts, so that the blade 222 is stably mounted.

The paddle holder 221 enables the paddle 222 to rotate by being fixedly connected to the centering shaft 212. Wherein, the inclined square of the blade 222 of the first propeller 22 is different from the inclined direction of the blade 222 of the second propeller 32. Therefore, the axial direction of the centering shaft 212 coincides with the axial direction of the rotation shaft of the first propeller 22. For convenience of explanation, the axial direction of the centering shaft 212 is defined as the Z-axis direction, and the direction in which the two paddles 222 are located is defined as the Y-axis direction. That is, the axial direction of the rotating shafts of the first propeller 22 and the second propeller 32 is the Z-axis direction, as shown in fig. 2.

A first motor 21 is mounted on one end of the wing 12 of the airframe 10. The first motor 21 is a forward rotation motor. The first motor 21 rotates the first propeller 22 in the forward direction. Referring to fig. 3, a centering hole 223 is formed on the paddle seat 221 of the first propeller 22, and the paddle seat 221 is disposed on the centering shaft 212 through the centering hole 223. The shape of the centering hole 223 is matched with the shape of the centering shaft 212, the centering shaft 212 rotates to drive the paddle holder 221 to rotate, and the paddle holder 221 drives the blades 222 to rotate, so that the first propeller 22 generates power.

Referring again to fig. 2, the forward rotary wing 20 further includes a first elastic member 23 for connecting the first motor 21 and the first propeller 22. The first elastic element 23 can enhance the connection strength of the first motor 21 and the first propeller 22, so as to ensure that the first propeller 22 can be stably arranged on the frame 10, and the first propeller 22 keeps stable connection with the centering shaft 212 during the rotation of the first propeller 22, thereby avoiding the risk of the first propeller 22 being out of shaft.

Referring to fig. 3 again, in the present embodiment, the first elastic element 23 is fixed on the first motor 21. The first elastic member 23 may be fixedly disposed on the rotating end 211 of the first motor 21 by means of screw connection, welding, etc. The first propeller 22 is mounted on the first motor 21 through a first elastic member 23. A receiving groove 219 is formed on the surface of the rotating end 211 of the first motor 21. One end of the first elastic member 23 contacting the rotating end 211 is accommodated in the accommodating groove 219, so that the first elastic member 23 is limited and the first elastic member 23 can be stably and fixedly connected with the rotating end 211.

The second motor 31 of the counter-rotating rotor 30 rotates the second propeller 32 in the reverse direction. The second elastic member 33 is fixed to the second motor 31. The second elastic member 33 may be fixedly disposed on the rotation end of the second motor 31 by means of screw connection, welding, or the like. The second propeller 32 is mounted on the second motor 31 through a second elastic member 33.

Referring to fig. 4, the paddle base 221 of the first propeller 22 is provided with a first engaging portion 224. When the first propeller 22 is mounted, the paddle holder 221 of the first propeller 22 can slide along the axial direction of the centering shaft 212, that is, the paddle holder 221 slides along the Z-axis. In the process that the paddle holder 221 moves along the Z axis, the first elastic member 23 moves to the position of the first engaging portion 224 and engages with the first engaging portion 224, so that the first propeller 22 is limited in the axial direction of the rotating shaft of the first motor 21, and therefore the first propeller 22 can be prevented from being separated from the centering shaft 212, which may cause a shaft separation risk.

The paddle mount 321 of the second propeller 32 is provided with a second engaging portion (not shown). When the second propeller 32 is mounted, the paddle mount 321 of the second propeller 32 can slide along the axial direction of the centering shaft, that is, the paddle mount 321 slides along the Z-axis. In the process that the paddle holder 321 moves along the Z axis, the second elastic element 33 moves to the position of the second engaging portion and engages with the second engaging portion, so that the second propeller 32 is limited in the axial direction of the rotating shaft of the second motor 31, and therefore the second propeller 32 can be prevented from being separated from the centering shaft and causing the risk of shaft disengagement.

It is understood that there may be at least one, but a plurality of first engaging portions 224 and second engaging portions. The number of the first engaging portions 224 and the second engaging portions is not limited herein. The number of the first engaging portions 224 of the first propeller 22 and the number of the second engaging portions of the second propeller 32 may be the same or different. The specific shapes of the first engaging portion 224 and the second engaging portion may be the same or different, and the first engaging portion 224 and the second engaging portion may be capable of holding the upper limit in the Z-axis direction with the first elastic material 23 and the second elastic material 33.

The first elastic member 23 and the second elastic member 33 are provided with hooks. The first engaging portion 224 of the first propeller 22 and the second engaging portion of the second propeller 32 are engaging grooves 25 for engaging with the hooks. The clamping groove 25 may be a through groove or a semi-closed groove. The first engaging portion 224 may be provided on an inner sidewall of the engaging groove 25 of the first propeller 22. A second engaging portion may be provided on an inner sidewall of the engaging groove of the second propeller 32.

Specifically, in the present embodiment, the first elastic member 23 and the second elastic member 33 are provided with hooks. The first propeller 22 and the second propeller 32 are both provided with a clamping groove. The hook and the slot are engaged with each other, so that the first elastic member 23 and the first propeller 22, and the second elastic member 33 and the second propeller 32 are engaged with each other more stably.

In another embodiment, the first elastic element 23 and the second elastic element 33 may be slots, and the first engaging portion 224 and the second engaging portion may be hooks or other engaging structures that engage with the slots. Therefore, the specific engaging structure between the first elastic member 23 and the first propeller 22, and between the second elastic member 33 and the second propeller 32 is not limited herein.

The first elastic element 23 and the second elastic element 33 each include a plurality of elastic arms and a connecting portion. The first elastic member 23 and the second elastic member 33 have substantially the same configuration, and the first elastic member 23 will be described as an example. The first propeller 22 and the second propeller 32 are also substantially identical in structural shape. For convenience of explanation, the first propeller 22 will be described as an example.

Referring to fig. 4 and 5, the first elastic element 23 may include a plurality of elastic arms 231 and a connecting portion 232. The elastic arm 231 is arranged corresponding to the slot 25, and the connecting portion 232 is used for being fixedly connected with the motor. The elastic arm 231 may be one or more. The card slot 25 may be one or more. The first elastic element 23 is adapted to the shape of the locking slot 25. The connection portion 232 may be fixed to the rotation end 211 of the motor by welding or screwing, etc.

In particular, in the present embodiment, the first elastic member 23 has a U-shape. The first elastic member 23 is provided with two elastic arms 231 arranged oppositely, and the connecting portion 232 is located between the two elastic arms 231. Correspondingly, the two clamping grooves 25 of the paddle seat 221 can also be arranged oppositely. The number of the elastic arms 231 may be three, four, etc., and the number of the locking grooves 25 may be three, four, etc. Moreover, the elastic arms 231 and the locking slots 25 are also distributed in a central symmetry manner about the rotation axis of the motor, so that the first elastic member 23 and the paddle seat 221 are kept under balanced stress.

The first elastic member 23 is of an integral structure. The first elastic member 23 is formed by bending a metal plate. Both ends of the first elastic member 23 are bent to form elastic arms 231 having elasticity. In other embodiments, the first elastic member 23 may be a separate structure. The plurality of elastic arms 231 are fixedly connected by a connecting portion 232.

Specifically, in the present embodiment, the centering shaft 212 of the motor passes through the connecting portion 232, and the two elastic arms 231 are engaged with the two engaging grooves 25 of the paddle holder 221 on both sides of the rotation shaft of the motor. The clamping acting force between the first elastic element 23 and the paddle seat 221 of the first propeller 22 can be symmetrically distributed on two sides of the rotating shaft, so that the acting force between the first elastic element 23 and the first propeller 22 can be relatively balanced, and the paddle seat 221 can be stably connected.

The two elastic arms 231 have the same structure, and the structure of one of the elastic arms 231 will be described in detail. The elastic arm 231 is formed with a hook. The trip can be one or more. Particularly in the present embodiment, the hook may include the first elastic portion 2311. As shown in fig. 4, the free end of the elastic arm 231 is bent to form a first elastic portion 2311, and the first elastic portion 2311 can slide into the locking groove 25 along the axial direction of the rotating shaft. As shown in fig. 5, when the first elastic portion 2311 passes through the catching groove 25, the first elastic portion 2311 is compressively deformed in an axial direction perpendicular to the rotation shaft to be caught in the catching groove 25 in the axial direction of the rotation shaft. That is, the first elastic portion 2311 contracts in the X-axis direction and is caught in the catching groove 25 in the Z-axis direction. As shown in fig. 6, the first elastic portion 2311 slides into the engaging groove 25, and is elastically deformed to be engaged and fixed with the engaging groove 25.

Also, the elastic arm 231 is provided with a groove 2313. The engaging protrusion 226 for engaging with the groove 2313 is provided in the seat 221 of the first propeller 22. When the first elastic portion 2311 is engaged with the engaging groove 25, the engaging protrusion 226 is also correspondingly engaged with the groove 2313 of the elastic arm 231, so as to form another engaging connection function, thereby enhancing the stability of the connection between the first elastic element 23 and the first propeller 22.

Referring to fig. 4 and 5, in the present embodiment, the first elastic portion 2311 is a V-shaped structure formed by bending the free end of the elastic arm 231. The first elastic portion 2311 may include two angled clamping arms 2314. The intersection of the two clamping arms 2314 is in a smooth transition with a round angle, so that the first elastic part 2311 can penetrate into the clamping groove 25.

Also, a bent back portion 2315 is provided at a free end of the first elastic portion 2311. The bent-back portion 2315 is formed by bending the free end of one of the arms 2314 toward the other arm 2314. Referring to fig. 6, the engaging protrusion 226 is provided with a first limiting surface 2261. The bent portion 2315 abuts against the first stopper surface 2261, and a first stopper force is applied between the bent portion 2315 and the engaging protrusion 226 in the direction along the rotation axis. The first limiting force can balance the reaction force of the first propeller 22 along the direction of the rotating shaft in the rotating process, and the first limiting force can prevent the first propeller 22 from being off-axis.

In addition, in the rotation process of the first propeller 22, the reaction force generated by the buoyancy can tighten the abutting relationship between the first elastic member 23 and the first limiting surface 2261, and further strengthen the fastening relationship between the first elastic member 23 and the fastening protrusion 226, so that the rotation operation of the first propeller 22 can not only prevent the first propeller 22 from being disengaged from the shaft, but also further strengthen the fastening relationship between the first propeller 22 and the first elastic member 23.

The bent portion 2315 increases a contact area between the first elastic portion 2311 and the engaging protrusion 226, so that the bent portion 2315 and the first stopper surface 2261 of the engaging protrusion 226 are kept in surface contact, and the first elastic portion 2311 and the engaging protrusion 226 are kept stable.

Also, the elastic arm 231 further includes a second elastic portion 2312. The second elastic portion 2312 is of a bent structure. The second elastic portion 2312 is formed by bending one end of the elastic arm 231 away from the first elastic portion 2311. The second elastic portion 2312 is elastically deformable in the Z-axis direction.

When the first elastic portion 2311 is engaged with the engaging protrusion 226, the first elastic element 23 receives a force along the rotation axis direction. This force tends to cause the second elastic portion 2312 to be elastically deformed in the axial direction of the rotary shaft. The second elastic portion 2312 is provided with a holding surface 2316. The engaging protrusion 226 has a second limiting surface 2262. The abutting surface 2316 and the second limiting surface 2262 abut against each other, and a second limiting force exists between the abutting surface 2316 and the second limiting surface 2262 along the direction of the rotating shaft. The second limiting force can offset a part of the acting force between the first elastic portion 2311 and the clamping protrusion 226, and the second limiting surface 2262 can support the second elastic portion 2312, so that the first elastic portion 2311 is prevented from being greatly deformed, and the elastic arm 231 can be stably clamped in the clamping groove 25.

The first and second limiting surfaces 2261 and 2262 are inclined with respect to each other. The first and second limiting surfaces 2261 and 2262 both form an included angle with the direction of the rotation axis. The first and second limiting surfaces 2261 and 2262 are two sides of the engaging protrusion 226, and therefore, the engaging protrusion 226 is wedge-shaped. Moreover, the second stopper surface 2262 is inclined with respect to the rotation axis direction, and the second stopper surface 2262 can guide the first elastic portion 2311 to be clamped into the clamping groove 25, thereby playing a guiding role.

The first stopper surface 2261 and the second stopper surface 2262 are both planar surfaces. The first and second limiting surfaces 2261 and 2262 are in surface contact with the elastic arm 231, so as to ensure stable contact between the elastic arm 231 and the engaging protrusion 226.

When the first propeller 22 needs to be detached, the first elastic member 23 can be elastically deformed, so that the first propeller 22 freely slides along the axial direction of the rotating shaft of the first motor 21 to be separated from the first clamping portion 224, thereby realizing detachable connection between the first propeller 22 and the first elastic member 23, and being convenient to operate.

Specifically, when the first propeller 22 is detached, referring to fig. 5, first, the first elastic portion 2311 of the first elastic member 23 is elastically deformed, and the first elastic portion 2311 is contracted and deformed along the X-axis direction, so that the first elastic portion 2311 is separated from the first limiting surface 2261 of the engaging protrusion 226, and the first elastic member 23 can slide out from the engaging groove 25 along the axial direction of the rotating shaft, thereby separating the first propeller 22 from the first elastic member 23. The two first elastic members 23 are disposed opposite to each other, and an operator can simultaneously hold the two first elastic members 23 and knead the two first elastic members 23 to each other, that is, the two first elastic members 23 can be simultaneously contracted and deformed. Referring to fig. 3 and 4, the first propeller 22 is pulled up along the Z-axis direction, so as to detach the first elastic element 23 from the first propeller 22.

Specifically, in the present embodiment, the paddle seat 221 of the first propeller 22 is provided with an avoiding notch 227 outside the slot 25, and the avoiding notch 227 exposes the first elastic portion 2311, that is, the clip arms 2314 of the first elastic portion 2311. Through this dodging breach 227, operating personnel can directly operate first elastic component 2311's arm lock 2314, through pressing first elastic component 2311, makes arm lock 2314 shrink deformation, conveniently realizes the dismantlement of first elastic component 23.

The second elastic element 33 is similar to the first elastic element 23 in structure, the second propeller 32 is similar to the first propeller 22 in structure, and the fixing manner of the second elastic element 33 and the second propeller 32 is similar to the fixing manner of the first elastic element 23 and the first propeller 22, and the same parts are not repeated. Therefore, the second propeller 32 is engaged with the second engaging portion by the second elastic member 33, so that the second propeller 32 is restricted in the axial direction of the rotating shaft of the second motor 31, thereby preventing the second propeller 32 from being out of the shaft during rotation.

Referring to fig. 7 and 8, the first propeller 22 is different from the second propeller 32 in that the first propeller 22 is a forward propeller and the second propeller 32 is a reverse propeller. The first propeller 22 and the second propeller 32 rotate in opposite directions, so that when the first propeller 22 and the second propeller 32 are installed, a distinction needs to be made to avoid misassembly.

Specifically, in the present embodiment, the locking groove 25 of the first propeller 22 is a first locking groove 251 that opens in the first direction. The engaging groove 35 of the second propeller 32 is a second engaging groove 351 opened in the second direction. And the first direction is different from the second direction. Therefore, the extending directions of the first elastic element 23 and the second elastic element 33 are different, and it is ensured that the first elastic element 23 can be correspondingly installed in the first slot 251, and the second elastic element 33 can be correspondingly installed in the second slot 351.

Therefore, the first locking groove 251 and the second locking groove 351 can be distinguished according to different opening directions, so that the first propeller 22 and the second propeller 32, and the first elastic element 23 and the second elastic element 33 can be distinguished, and a foolproof effect can be achieved when the first propeller 22 and the second propeller 32 are installed.

Specifically, in the present embodiment, the first direction is inclined in the clockwise direction. The first direction is the direction after the Y-axis direction rotates clockwise by an acute angle. The second direction is inclined in a counterclockwise direction. The second direction is the direction after the Y-axis direction rotates along the anticlockwise acute angle.

It is understood that in other embodiments, the forward rotor 20 and the reverse rotor 30 may also be provided with other mechanical fool-proofing designs, such as the shape design of the centering shaft 212, the centering hole 223, and the like.

Above-mentioned many rotor unmanned vehicles's screw is injectd in Z axle direction to at the screw in the rotation process, the screw can not follow the axial displacement of rotation axis, avoid screw and rotation axis to break away from, danger such as emergence flight accident.

The propeller is mounted in a direction of sliding along the axial direction of the rotating shaft until being engaged and fixed, and the mounting direction of the propeller is independent of the rotating direction of the propeller. Even if the different rotation directions of the first propeller 22 and the second propeller 32 do not have an interfering effect on the fixed mounting of the propellers. Therefore, the installation mode of the multi-rotor unmanned aerial vehicle makes the installation and operation of the propellers more convenient and ensures the installation qualification rate of the propellers.
