A aerocar wing fold structure 100 according to an embodiment of the present invention is described below with reference to fig. 1-10.

As shown in fig. 1-9, a folding structure 100 for a wing of a flying car according to an embodiment of the present invention includes: a fixed wing 20 and a rotating wing 40.

The rotary wing 40 is rotatably coupled to the fixed wing 20, and the rotary wing 40 has a folded position and an unfolded position. Wherein, one of the fixed wing 20 and the rotating wing 40 is provided with a first connecting portion 21, and the other is provided with a second connecting portion 41, when the rotating wing 40 is in the unfolded position, the first connecting portion 21 is fixedly matched with the second connecting portion 41, and when the rotating wing 40 is in the folded position, the first connecting portion 21 is separated from the second connecting portion 41.

Therefore, when the rotary wing 40 is located at the unfolding position, the first connecting portion 21 and the second connecting portion 41 are fixedly matched, so that the connection strength of the rotary wing 40 and the fixed wing 20 can be enhanced, the structural stability of the rotary wing 40 can be enhanced, the rotary wing 40 can bear bending moment received during flying, and the aerocar 1000 can fly in the air in a fixed wing mode.

For example, the fixed wing 20 is fixedly mounted on the aerocar 1000, two rotating wings 40 are provided, the two rotating wings 40 are symmetrically distributed on two sides of the fixed wing 20, and when the rotating wings 40 are located at the unfolding positions, the rotating wings 40 and the fixed wing 20 are unfolded in a straight line, so that the aerocar 1000 can fly in the air to have enough lift force, and in the process that the rotating wings 40 rotate from the unfolding positions to the folding positions, the rotating wings 40 rotate and shrink towards the tail direction of the aerocar 1000 relative to the fixed wing 20, so that when the rotating wings 40 are located at the folding positions, the width of the wing folding structure 100 is approximate to the width of the car body, and the influence on the width dimension of the aerocar 1000 is reduced, so that the aerocar 1000 can run on a regular road surface.

In the related art, when the rotary wing 40 is deployed, the strength of the connection between the rotary wing 40 and the fixed wing 20 is low, so that the rotary wing 40 cannot withstand the bending moment applied during flight, and the aerocar 1000 cannot fly in the fixed wing mode stably.

In the present invention, when the rotary wing 40 is in the extended position, the rotary wing 40 and the fixed wing 20 can be fixedly engaged with each other by the first connection portion 21 and the second connection portion 41, so that the connection strength between the rotary wing 40 and the fixed wing 20 can be enhanced, and the rotary wing 40 of the aerocar 1000 can withstand the bending moment applied to the aerocar when the aerocar is in the extended position and the rotary wing 40 maintains the mode of the fixed wing when the aerocar is in flight.

According to the aerocar wing folding structure 100 of the embodiment of the present invention, the fixed wing 20 is rotatably connected with the rotating wing 40, the rotating wing 40 is provided with a folding position and an unfolding position, and when the rotating wing 40 is in the unfolding position, the first connecting portion 21 and the second connecting portion 41 are fixedly matched, so that the connection strength between the rotating wing 40 and the fixed wing 20 can be enhanced, the structural stability of the rotating wing 40 can be enhanced, the rotating wing 40 can bear bending moment applied to the rotating wing during flying, and the aerocar 1000 flies in the air in a fixed wing mode.

In some embodiments, as shown in fig. 7 and 9, one of the first and second connection portions 21 and 41 is configured as a support bar 22, and the other is configured as a socket groove 42, the support bar 22 being adapted for a socket fit with the socket groove 42.

Therefore, when the rotary wing 40 is unfolded, the supporting rods 22 can be inserted into the inserting grooves 42 to enhance the connection strength between the rotary wing 40 and the fixed wing 20, and the supporting rods 22 are inserted into the inserting grooves 42 so that the supporting rods 22 are not directly visible on the outer side of the wing folding structure 100, thereby being convenient for reducing the influence on the size of the wing folding structure 100 and being beneficial to realizing the miniaturization design of the wing folding structure 100.

For example, when the first connecting portion 21 is configured as the support bar 22, the second connecting portion 41 is configured as the insertion groove 42, and vice versa, in this embodiment, the first connecting portion 21 is configured as the support bar 22, the second connecting portion 41 is configured as the insertion groove 42, and the support bar 22 is engaged with the insertion groove 42.

For example, the first connection portion 21 may be disposed on the fixed wing 20, and the second connection portion 41 may be disposed on the rotating wing 40, and vice versa, in this embodiment, the first connection portion 21 is disposed on the fixed wing 20, and the second connection portion 41 is disposed on the rotating wing 40, so that the support rod 22 is disposed on the fixed wing 20, the inserting slot 42 is disposed on the rotating wing 40, and when the rotating wing 40 is in the extended position, the support rod 22 may be inserted into the inserting slot 42 to enhance the connection strength between the rotating wing 40 and the fixed wing 20, so that the rotating wing 40 can bear the bending moment suffered by the flying.

In some embodiments, as shown in fig. 7 and 9, the support bar 22 is mounted on the fixed wing 20, the insertion slot 42 is provided on the rotating wing 40, the fixed wing 20 is provided with a driving member 25, and the driving member 25 is used to drive the support bar 22 to move toward or away from the insertion slot 42 when the rotating wing 40 is in the deployed position.

Therefore, by arranging the driving piece 25, the movement of the supporting rod 22 does not need to be controlled manually when the supporting rod 22 is in plug-in fit with the plug-in groove 42, so that the automation degree of the wing folding structure 100 is improved.

For example, when the rotary wing 40 is in the extended position, the driving member 25 can drive the support bar 22 to move toward the insertion slot 42 so that the support bar 22 can extend into the insertion slot 42, or when the rotary wing 40 is moved from the extended position to the folded position, the driving member 25 drives the support bar 22 to move away from the insertion slot 42 so that the support bar 22 is separated from the insertion slot 42, thereby enabling the rotary wing 40 to rotate on the fixed wing 20.

In this way, the movement of the support bar 22 can be driven by the driving member 25, so as to achieve an improvement in the automation degree of the wing-folding structure 100.

In some embodiments, as shown in fig. 2 and 7, the fixed wing 20 is provided with a mounting cavity 23, and the support bar 22 is slidably mounted within the mounting cavity 23.

Therefore, the support rods 22 are not directly visible on the outer side of the fixed wing 20, so that the influence on the size of the fixed wing 20 is reduced, and the miniaturization design of the fixed wing 20 is realized.

Meanwhile, when the rotary wing 40 is located at the unfolding position, the supporting rods 22 can slide from the mounting cavity 23 towards the inserting grooves 42, so that the end parts of the supporting rods 22 can extend into the inserting grooves 42, and therefore the connection strength between the rotary wing 40 and the fixed wing 20 can be enhanced, and when the rotary wing 40 needs to move from the unfolding position to the folding position, the end parts of the supporting rods 22 move from the inserting grooves 42 into the mounting cavity 23, and therefore the rotary wing 40 is not limited in movement.

It should be noted that, when the rotary wing 40 is located at the unfolding position, the opening of the installation cavity 23 is opposite to the opening of the inserting groove 42, and meanwhile, the inner wall of the installation cavity 23 can play a role in guiding and limiting the movement of the support rod 22, so as to ensure that the support rod 22 can directly move into the inserting groove 42.

In some embodiments, as shown in fig. 6, the driving member 25 is configured as a driving motor, the driving motor is located on a motor mounting surface 231 in the mounting cavity 23, and the supporting rod 22 includes a first sub-rod 26 and a second sub-rod 27, the first sub-rod 26 is fixedly connected with an output shaft of the driving motor, and the second sub-rod 27 is sleeved outside the first sub-rod 26. Wherein, the outer periphery wall of the first sub-rod 26 is provided with external threads, and the inner periphery wall of the second sub-rod 27 is provided with internal threads, and the external threads are in threaded connection with the internal threads.

Thus, the rotation of the first sub-lever 26 can drive the second sub-lever 27 to move in the axial direction of the first sub-lever 26 when the driving member 25 drives the first sub-lever 26 to rotate.

Therefore, when the rotary wing 40 is located at the unfolding position, the driving motor drives the first sub-rod 26 to rotate and then drives the second sub-rod 27 to move along the axial direction of the first sub-rod 26, so that the end part of the first sub-rod 26 extends into the inserting groove 42, and the connection strength between the rotary wing 40 and the fixed wing 20 can be enhanced, and when the rotary wing 40 moves from the unfolding position to the folding position, the driving motor drives the first sub-rod 26 to rotate and then controls the second sub-rod 27 to leave from the inserting groove 42, so that the rotary wing 40 can be folded.

Alternatively, when the first sub-rod 26 is fixedly connected to the output shaft of the driving motor, the connection manner may have various forms, for example, when the first sub-rod 26 is connected to the output shaft of the driving motor, it may be directly plugged onto the output shaft, or when the first sub-rod 26 is connected to the output shaft of the driving motor, it is fixed together through a threaded connection, preferably, in this embodiment, the first sub-rod 26 is directly plugged onto the output shaft of the driving motor.

Alternatively, after the first sub-rod 26 is screwed with the second sub-rod 27, the screw direction of the first sub-rod 26 and the second sub-rod 27 is not limited, for example, when the first sub-rod 26 rotates clockwise to drive the second sub-rod 27 to approach the socket 42, the first sub-rod 26 rotates counterclockwise to drive the second sub-rod 27 to move away from the socket 42, or when the first sub-rod 26 rotates clockwise to drive the second sub-rod 27 to move away from the socket 42, the first sub-rod 26 rotates counterclockwise to drive the second sub-rod 27 to move toward the direction approaching the socket 42.

In some embodiments, as shown in fig. 7, the first sub-rod 26 includes a rod body 261 and a connecting portion 262, the external thread is disposed on an outer peripheral wall of the rod body 261, and the connecting portion 262 is connected with the rod body 261 and sleeved on an outer side of an output shaft of the driving motor.

In other words, the outer peripheral wall of the rod body 261 of the first sub-rod 26 is provided with an external thread matching with an internal thread on the inner peripheral wall of the second sub-rod 27, so that the first sub-rod 26 can drive the second sub-rod 27 to move towards a direction approaching or separating from the inserting slot 42, the connecting portion 262 of the first sub-rod 26 is sleeved outside the output shaft of the driving motor, and the connecting portion 262 is connected with the rod body 261, so that the driving motor can drive the second sub-rod 27 by driving the first sub-rod 26.

Therefore, in the present embodiment, the first sub-rod 26 is sleeved on the output shaft of the driving motor, so that the first sub-rod 26 is more convenient when connected with the output shaft of the driving motor, and the first sub-rod 26 is coaxial with the output shaft of the driving motor after the installation is completed, so that the power of the driving motor can be better transmitted to the first sub-rod 26.

In some embodiments, as shown in fig. 7, a bearing 28 is further disposed in the mounting cavity 23, and the bearing 28 is sleeved outside the connecting portion 262.

It will be appreciated that the bearing 28 in the mounting cavity 23 is disposed around the outer side of the connecting portion 262, and the bearing 28 can better fix the first sub-rod 26 to the driving motor.

Optionally, a support rod mounting groove 232, a bearing outer ring mounting surface 233 and a bearing outer ring gland mounting surface 234 are provided in the mounting cavity 23 of the fixed wing 20, the support rod 22 is firstly mounted in the support rod mounting groove 232, then the bearing 28 is placed on the bearing outer ring mounting surface 233, at this time, the connecting portion 262 of the first sub-rod 26 is clamped in the bearing 28, a bearing outer ring gland 281 and a bearing inner ring gland 282 are provided on one side of the bearing 28, which is close to the driving motor, the bearing outer ring gland 281 is mounted on the bearing outer ring gland mounting surface 234 in a threaded connection manner, and the bearing inner ring gland 282 is sleeved on the connecting portion 262 of the first sub-rod 26, so that the bearing 28 can limit the connecting portion 262 of the first sub-rod 26, and the first sub-rod 26 can be better connected to the output shaft of the driving motor.
