[0024] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] The rotors of vehicles in related technologies generally achieve the locking of the blades and the hub by adding external structural parts such as blade restraint straps and blade restraint sleeves. However, this solution requires manual operation, which involves manually pushing the blades to the corresponding position and then installing the blade restraint structure to lock the blades. This solution is simple to use but inefficient, and the blade locking time is relatively long.

[0027] See also Figure 1 An embodiment of the present invention provides a vehicle 1000, which may be a flying car, a helicopter, a drone or others.

[0028] The vehicle 1000 includes a fuselage 200 and a rotor 100, wherein the rotor 100 is connected to the fuselage 200. The vehicle 1000 may have an extended posture and a stowed posture, and the rotor 100 of the vehicle 1000 in different postures is in different situations. For example, when the vehicle 1000 is in an extended posture, the rotor 100 is extended, and the rotor 100 can provide lift for the vehicle 1000, so that the vehicle 1000 can fly. For another example, when the vehicle 1000 is in a stowed posture, the rotor 100 is folded and stowed, so as to reduce the space occupied by the vehicle 1000.

[0029] Please also read Figure 2 and Figure 3 The embodiment of the utility model provides a rotor 100, which includes a hub 11, a blade 12 and a locking mechanism 13, wherein the blade 12 is rotatably connected to the hub 11 around a first direction X. In this way, the blade 12 can be rotated around the first direction X to different positions to meet the use requirements of the vehicle 1000 in different situations, for example, the blade 12 can be rotated around the first direction X relative to the hub 11 to a folded storage position and an unfolded use position.

[0030] For example, the blades 12 rotate about the first direction X to be in the deployed use position, so that the vehicle 1000 can be in the deployed posture to meet the flight requirements of the vehicle 1000; for another example, the blades 12 rotate about the first direction X to be in the folded storage position, so that the vehicle 1000 is in the storage posture.

[0031] In some embodiments, the rotor 100 may be a multi-blade rotor, that is, the rotor 100 may have a plurality of blades 12, for example, the number of blades 12 may be two, three or other numbers. In the case where the rotor 100 has a plurality of blades 12, the plurality of blades 12 may all rotate relative to the hub 11 about the first direction X. For example, the plurality of blades 12 may all rotate relative to the hub 11 about the first direction X and move closer to each other to be in a folded storage position. For another example, the two blades 12 may all rotate relative to the hub 11 about the first direction X and move away from each other to be in an unfolded use position.

[0032] In some embodiments, the locking mechanism 13 includes a locking member 131 and a locking driver 132, wherein the locking member 131 is telescopically disposed in the hub 11 along a second direction Y different from the first direction X, and the locking driver 132 is movably disposed in the hub 11 and can move relative to the hub 11 to be in a locked position and an unlocked position. The locking driver 132 drives the locking member 131 to partially extend into the blade 12 along the second direction Y to be in a locked position, and the locking member 131 can lock the blade 12 by placing the locking driver 132 in the locked position. The locking driver 132 provides the locking member 131 with a movement amount to withdraw from the blade 12 along the second direction Y to be in an unlocked position, and the locking member 131 can withdraw from the blade 12 by placing the locking driver 132 in the unlocked position, and the locking member 131 does not limit the blade 12, so that the blade 12 can rotate to a desired position relative to the hub 11.

[0033] In this way, the locking member 131 can be partially extended into the blade 12 along the second direction Y by the locking driving member 132 to lock the blade 12, and the locking member 131 can limit the blade 12 so that the blade 12 can be stably maintained in the position relative to the hub 11, which helps to reduce the shaking and displacement of the blade 12. The locking mechanism 13 locks the blade 12 in a simple manner, which is convenient for manufacturing the rotor 100. Among them, the locking member 131 withdrawing from the blade 12 can be understood as the locking member 131 does not restrict or limit the blade 12, for example, the locking member 131 can be retracted into the hub 11.

[0034] In some embodiments, the number of locking members 131 may be consistent with the number of blades 12, and the locking driver 132 may synchronously drive the plurality of locking members 131 to extend into the corresponding blades 12, so that the locking driver 132 may drive the plurality of locking members 131 to lock the blades 12. For example, if the number of blades 12 is two, then the number of locking members 131 is also two, and the driver 132 may synchronously drive the two locking members 131 to extend into the corresponding blades 12 respectively.

[0035] Please also read Figure 3 and Figure 4 In some embodiments, the locking member 131 may include a latch 133 and a reset body 134, wherein the latch 133 is movably disposed in the hub 11 along the second direction Y, and the reset body 134 is connected to the latch 133 and the hub 11, and is adapted to provide an elastic force for the latch 133 to move toward the locking driver 132 along the second direction Y. The locking driver 132 drives the latch 133 along the second direction Y to overcome the elastic force of the reset body 134 and partially extend into the blade 12 to be in the locked position, and when the locking driver 132 is in the unlocked position, the reset body 134 drives the latch 133 along the second direction Y to exit the blade 12.

[0036] In this way, the reset body 134 can provide an elastic force for the pin 133 to move along the second direction Y toward the locking drive member 132, so that the elastic force of the reset body 134 can drive the pin 133 to withdraw from the blade 12, thereby allowing the locking member 131 to be automatically reset when the locking drive member 132 is in the unlocked position. There is no need for the user to provide additional reset operations for the locking member 131, which helps to improve the efficiency of the locking mechanism 13 in unlocking the blade 12.

[0037] In some embodiments, the reset body 134 may be a spring, for example, the reset body 134 may be a compression spring, a tension spring, etc.

[0038] In some embodiments, the latch 133 may include a pin body 1331 and a limiting cover 1332, the pin body 1331 is movably disposed in the hub 11 along the second direction Y, the limiting cover 1332 is connected to the pin body 1331 and forms a receiving space 1333 with the outer peripheral surface of the pin body 1331, the opening of the limiting cover 1332 faces the side away from the locking drive member 132, one end of the reset body 134 is located in the receiving space 1333, and the other end of the reset body 134 is located outside the receiving space 1333 and abuts against the hub 11. The reset body 134 in this embodiment may be a compression spring.

[0039] This helps to improve the compactness of the structure of the latch 133 and the reset body 134 , and also helps to reduce the risk of the reset body 134 being loosened from the latch 133 , which helps to ensure the normal operation of the reset body 134 .

[0040] Exemplarily, when the locking drive 132 is in the locking position, the locking drive 132 drives the latch 133 to move along the second direction Y toward the blade 12, and the reset body 134 is located at one end of the receiving space 1333 and moves synchronously with the limit cover 1332 and the pin body 1331 along the second direction Y toward the blade 12, and partially extends into the blade 12; when the locking drive 132 is in the unlocking position, the reset body 134 is located at one end of the receiving space 1333 and drives the limit cover 1332 and the pin body 1331 to move synchronously along the second direction Y away from the blade 12, and exit the blade 12.

[0041] Please also read Figure 3 , Figure 4 and Figure 5 In some embodiments, the locking drive 132 may include an electric push rod 135 and a sliding rod 136, wherein the electric push rod 135 is connected to the sliding rod 136 and is suitable for driving the sliding rod 136 to reciprocate along the first direction X. The electric push rod 135 and the propeller hub 11 are integrated and installed in an integrated manner, and the internal power supply and communication of the electric push rod 135 can be controlled by a control instruction issued by the controller of the vehicle 1000, so that the electric push rod 135 drives the sliding rod 136 to reciprocate along the first direction X or stop moving, which can be specifically set according to actual conditions.

[0042] In some embodiments, the slide bar 136 may have a slide bar side surface 1364, the slide bar side surface 1364 abuts against an end of the locking member 131 away from the blade 12, and the distance between the slide bar side surface 1364 and the blade 12 decreases along the first direction X. In this way, the movement of the slide bar side surface 1364 along the first direction X can be converted into the movement of the locking member 131 along the second direction Y, thereby helping to ensure the normal operation of the locking mechanism 13.

[0043] Exemplarily, when the electric push rod 135 drives the sliding rod 136 to move along the first direction X, for example, when the electric push rod 135 drives the sliding rod 136 to move downward along the first direction X, the locking member 131 is always in contact with the sliding rod side 1364 and the sliding rod side 1364 always provides a force for the locking member 131 to move along the second direction Y toward the blade 12, so that the locking member 131 will move along the second direction Y toward the blade 12 as the sliding rod side 1364 moves downward and partially extend into the blade 12, thereby realizing the locking of the blade 12 by the locking member 131, which helps to realize the automatic control of the locking function of the locking mechanism 13, and there is no need to manually lock the blade 12 and the hub 11 by means of a blade strap, a blade sleeve, etc.

[0044] When the electric push rod 135 drives the slide bar 136 to move along the first direction X, for example, when the electric push rod 135 drives the slide bar 136 to move upward along the first direction X, the slide bar 136 can provide the locking member 131 with a movement amount to withdraw the blade 12 along the second direction Y, and the reset body 134 can drive the latch 133 to move along the second direction Y and withdraw the blade 12, thereby realizing the unlocking of the blade 12 by the locking member 131.

[0045] The slide bar side 1364 may be an inclined surface, which helps to improve the smoothness of the transition between the slide bar side 1364 and the locking member 131. In other embodiments, the slide bar side 1364 may also be other, for example, the slide bar side 1364 may be an arc surface, etc., which may be specifically set according to actual conditions.

[0046] In some embodiments, the hub 11 may be provided with a guide sliding hole 111, the hub 11 has a guide sliding wall 112 surrounding the guide sliding hole 111, the slide bar 136 is located in the guide sliding hole 111, the slide bar 136 includes a sliding portion 1361, and the sliding portion 1361 is slidably abutted against the guide sliding wall 112. In this way, it is helpful to improve the stability of the slide bar 136 sliding in the guide sliding hole 111, and it is helpful to reduce the shaking of the slide bar 136 when sliding.

[0047] In some embodiments, the sliding bar side 1364 is spaced from the guide sliding wall 112, so that the sliding bar side 1364 will not hinder the sliding of the sliding bar 136 in the guide sliding hole 111, which helps to reduce the contact friction between the sliding bar side 1364 and the guide sliding wall 112, thereby helping to better improve the smoothness of the sliding of the sliding bar 136 in the guide sliding hole 111.

[0048] In some embodiments, the sliding portion 1361 may include a first sliding end 1362 and a second sliding end 1363, the sliding rod side 1364 is located between the first sliding end 1362 and the second sliding end 1363, the first sliding end 1362 covers the sliding rod side 1364 toward the second sliding end 1363, the second sliding end 1363 covers the sliding rod side 1364 toward the first sliding end 1362, and the electric push rod 135 is connected to the side of the first sliding end 1362 away from the sliding rod side 1364.

[0049] In this way, the first sliding end 1362 and the second sliding end 1363 can jointly guide the sliding rod 136, so that the sliding rod 136 can slide in the guiding hole 111 through the first sliding end 1362 and the second sliding end 1363, which helps to better improve the stability of the sliding rod 136 sliding in the guiding hole 111, so as to better reduce the shaking of the sliding rod 136 when sliding.

[0050] In addition, since the first sliding end 1362 covers the sliding bar side 1364 toward the direction of the second sliding end 1363, and the second sliding end 1363 covers the sliding bar side 1364 toward the direction of the first sliding end 1362, the first sliding end 1362 and the second sliding end 1363 can also provide certain protection for the sliding bar side 1364, which helps to reduce the situation where the sliding bar side 1364 is exposed and damaged.

[0051] Please also read Figure 3 and Figure 6 In some embodiments, the rotor 100 may include a blade folding drive 14, which is mounted on the hub 11 and connected to the blade 12. When the locking drive 132 is in the unlocked position and the locking drive 131 exits the blade 12, the blade folding drive 14 is suitable for driving the blade 12 to rotate around the first direction X from the unfolded use position to the folded storage position.

[0052] In this way, the rotor 100 can realize the folding and storage of the blades 12 through the blade folding drive 14, thereby eliminating the need to fold the blades 12 through manual operation.

[0053] In some embodiments, the blade 12 may have a blade shaft 123, and the blade shaft 123 is rotatably connected to the hub 11 around the first direction X. The blade folding drive 14 may include a folding motor, and the driving end of the folding motor is connected to the blade shaft 123 and is suitable for driving the blade 12 to rotate from the unfolded use position to the folded storage position around the first direction X. In addition, the driving end of the folding motor can also drive the blade 12 to rotate around the first direction X from the folded storage position to the unfolded use position.

[0054] In this way, the folding motor can provide a driving force for the blade 12 to rotate around the first direction X, so that the driving force of the folding motor can drive the blade 12 to rotate around the first direction X from the unfolded use position to the folded storage position, thereby eliminating the need for manual operation to fold or unfold the blade 12.

[0055] In some embodiments, in addition to the above-mentioned method of using a folding motor, the blade folding drive member 14 can also be replaced by other structures. For example, the blade folding drive member 14 can include a torsion spring 141, which is sleeved on the outer periphery of the blade rotating shaft 123 and connected to the blade 12 and the hub 11. When the locking drive member 132 is in the unlocked position, the elastic force of the torsion spring 141 is suitable for driving the blade 12 to rotate around the first direction X from the unfolded use position to the folded storage position.

[0056] Thus, when the locking drive member 132 is in the unlocked position, the torsion spring 141 can drive the blade 12 to rotate around the first direction X to the folded storage position, thereby eliminating the need for manual operation to fold the blade 12. In addition, the torsion spring 141 has a simple structure and low manufacturing cost, which helps reduce the manufacturing cost of the rotor 100.

[0057] In addition, when the blades 12 need to be in the deployed position, the drive structure of the rotor 100 can drive the hub 11 to rotate, so that the hub 11 and the blades 12 rotate synchronously, and during the rotation of the hub 11 and the blades 12, the blades 12 can overcome the elastic force of the torsion spring 141 under the action of the centrifugal force and rotate relative to the hub 11 around the first direction X, so that the blades 12 rotate relative to the hub 11 to the deployed position. In addition, when the hub 11 gradually stops rotating, the centrifugal force on the blades 12 also gradually decreases, and finally, under the action of the elastic force of the torsion spring 141, the blades 12 can be driven to rotate relative to the hub 11 to the folded storage position.

[0058] In some embodiments, the paddle 12 may be provided with a first locking hole 121 and a second locking hole 122, both of which penetrate the outer surface of the paddle 12 and are spaced apart. When the paddle 12 is in the deployed position, the locking member 131 is opposite to the first locking hole 121 and is misaligned with the second locking hole 122, and the locking drive member 132 can drive the locking member 131 to be partially located in the first locking hole 121 to be in the locked position. In this way, the locking mechanism 13 can lock the paddle 12 when the paddle 12 is in the deployed position, which helps to reduce the situation where the paddle 12 shakes and shifts in the deployed state and affects the use.

[0059] When the blade 12 is in the folded storage position, the locking member 131 is opposite to the second locking hole 122 and is misaligned with the first locking hole 121, and the locking driving member 132 can drive the locking member 131 to be partially located in the second locking hole 122 to be in the locked position. In this way, the locking mechanism 13 can lock the blade 12 when the blade 12 is in the folded storage position, which helps to reduce the shaking and displacement of the blade 12 in the folded storage state, and helps to reduce the vibration and rotation displacement caused during the transportation of the rotor 100.

[0060] In this way, when the paddle 12 is in the unfolded use position or the folded storage position, the locking mechanism 13 can lock the paddle 12 .

[0061] Re-read Figure 3 and Figure 4In some embodiments, the hub 11 may be provided with a hub locking hole 113. When the blade 12 is in the unfolded use position and the locking drive 132 is in the locking position, the first locking hole 121 is aligned with the hub locking hole 113, and the locking drive 132 drives the locking member 131 to penetrate the hub locking hole 113 along the second direction Y and is partially located in the first locking hole 121, thereby locking the blade 12. When the blade 12 is in the unfolded, folded and stored position and the locking drive 132 is in the locking position, the second locking hole 122 is aligned with the hub locking hole 113, and the locking drive 132 drives the locking member 131 to penetrate the hub locking hole 113 along the second direction Y and is partially located in the first locking hole 122, thereby locking the blade 12.

[0062] In summary, the rotor 100 and the vehicle 1000 provided by the embodiment of the utility model, the blade 12 of the rotor 100 is rotatably connected to the hub 11 around the first direction X. The locking member 131 of the locking mechanism 13 is telescopically arranged in the hub 11 along the second direction Y different from the first direction X, and the locking driving member 132 is movably arranged in the hub 11, and can move relative to the hub 11 to be in a locked position and an unlocked position, and the locking driving member 132 drives the locking member 131 to partially extend into the blade 12 along the second direction Y to be in a locked position, then the locking member 131 can limit the blade 12, so that the blade 12 can be stably maintained in the position relative to the hub 11, which helps to reduce the shaking and displacement of the blade 12. The locking drive 132 provides the locking member 131 with a movement amount along the second direction Y to withdraw the blade 12 to be in the unlocked position. The locking drive 132 can be placed in the unlocked position so that the locking member 131 can withdraw the blade 12. The locking member 131 does not limit the blade 12, which facilitates the rotation of the blade 12 to the desired position relative to the hub 11.
