Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a rotor structure and a UAV having the same. Background Technology

[0002] Current drones are generally bulky and inconvenient to carry due to limitations in rotor structure and wing size. Traditional solutions often employ detachable designs, but these have significant drawbacks:

[0003] 1. Cumbersome disassembly and assembly: Users need to repeatedly assemble propellers, wings and other parts, which is time-consuming and prone to losing parts;

[0004] 2. Poor structural stability: The disassembly interface is prone to wear, which can lead to loose connections during flight, affecting safety and control accuracy;

[0005] 3. Limited folding effect: Most folding designs only address wing folding and landing gear optimization, lacking improvements in blade storage. After folding the wings, the overall volume of the aircraft is only compressed to a limited extent.

[0006] Therefore, there is an urgent need for a drone structure that can be quickly folded / unfolded without disassembly, so as to significantly improve portability while ensuring flight stability. Utility Model Content

[0007] The purpose of this invention is to provide a rotor structure and a drone having the same, in order to solve the problems in the prior art.

[0008] To solve the above problems, the present invention adopts the following technical solution:

[0009] A rotor structure, comprising:

[0010] Drive motor;

[0011] Mounting base, which is rotatably mounted on the motor shaft of the drive motor;

[0012] A pair of blades, each blade being a single-wing blade, are symmetrically arranged on both sides of the rotating axis of the mounting base, and their mounting ends are rotatably connected to the mounting base via a rotating shaft. Each blade's mounting end is provided with a positioning plate, and the positioning plate is provided with positioning holes. When the two blades are in a straight line, they are in their unfolded state. In the unfolded state, the two positioning plates are stacked together and their positioning holes are aligned.

[0013] A blade locking assembly is mounted on the mounting base and has a retractable locking rod. When the blade is in the deployed state, the locking rod can pass through positioning holes on the two positioning plates to lock the blade in the deployed state.

[0014] The beneficial effects of this utility model are: through the cooperation of the blades and the blade locking assembly, the blades of the rotor structure can be freely unfolded and retracted. When flight is required, the two blades are moved to be in the same straight line, and then the locking rod is used to pass through the positioning holes at the mounting ends of the two blades at the same time to complete the locking and limit the two blades to the unfolded state. When the drone needs to be stored, the locking effect between the locking rod and the blades is released, so that the blades can enter the retracted state, thereby reducing the actual wingspan of the wing and making it easier to store.

[0015] Furthermore, the mounting base includes a base and a cover. The lower end face of the base is fixedly connected to the motor shaft of the drive motor. The cover is mounted on the upper end face of the base. The blade is located between the base and the cover, and is rotatably connected to the upper end face of the base via the rotating shaft, and rotatably abuts against the lower end face of the cover.

[0016] A further beneficial effect of this utility model is that by setting a base and a cover to install the blade, the cover can effectively prevent the blade from falling off during high-speed rotation by rotating and abutting against the blade mounting end.

[0017] Furthermore, the lower end of the pressure cap is provided with an elastic limiting block corresponding to the mounting end of the blade. The mounting end of the blade is provided with an unfolding limiting groove and a retracting limiting groove respectively. The elastic limiting block can be engaged with the unfolding limiting groove or the retracting limiting groove to limit the rotation of the blade relative to the rotating shaft.

[0018] A further beneficial effect of this utility model is that by setting an unfolding position limiting groove and a retracting position limiting groove in conjunction with an elastic limiting block set on the lower end face of the pressure cap, the blade can be pre-locked. Especially when the unfolding position is limited, the blade can be effectively prevented from rotating, ensuring that the locking rod can smoothly lock the two blades.

[0019] Furthermore, the walls of the expansion and retraction limiting grooves are slopes that can guide the elastic limiting block in and out.

[0020] A further beneficial effect of this utility model is that by designing the walls of the expansion position limiting groove and the retraction position limiting groove as slopes, it is easier to guide the elastic limiting block into or out of the groove.

[0021] Furthermore, each blade has two expansion position limiting grooves and two retraction position limiting grooves, and each set of expansion position limiting grooves and retraction position limiting grooves are arranged opposite to each other, and each blade has two corresponding elastic limiting blocks.

[0022] A further beneficial effect of this utility model is that a set of two unfolding position limiting grooves and two retracting position limiting grooves, together with a set of two elastic limiting blocks, can further ensure the pre-locking effect.

[0023] Furthermore, the blade locking assembly also includes a pull rod, an abutment plate, and a drive spring. The pull rod passes vertically through the pressure cover and is slidably connected to it. One end of the pull rod is the operating end, and the other end is fixedly connected to the abutment plate. The drive spring is located between the pressure cover and the abutment plate. The locking rod is fixedly connected to the abutment plate. The drive spring has a tendency to cause the abutment plate to move the locking rod and pass through the positioning hole.

[0024] A further beneficial effect of this utility model is that by utilizing the elastic potential energy of the spring, the locking rod passes through the positioning hole. Under the action of the elastic potential energy, the locking rod is continuously subjected to force, ensuring the locking effect. When unlocking, it is only necessary to overcome the elastic potential energy of the spring to pull the operating end.

[0025] An unmanned aerial vehicle (UAV) includes a frame, multiple wings, multiple rotor structures corresponding to the number of wings, and landing gear. The multiple wings are evenly arranged circumferentially along the frame and mounted on the frame. The drive motors are mounted on the ends of the wings away from the frame. The landing gear is mounted below the frame.

[0026] The beneficial effects of this utility model are: by adopting a retractable rotor structure, the blades can be retracted and overlapped with the wings when the drone is not in use, thereby reducing the actual wing deployment and facilitating storage.

[0027] Furthermore, it also includes a wing shaft and a wing locking component. The side of the frame is provided with parallel wing clamps. The wing shaft is vertically and rotatably connected between the wing clamps. The mounting end of the wing is rotatably connected to the wing shaft. The wing locking component is rotatably mounted on the wing clamp and can be inserted into the mounting end of the wing to prevent the wing from rotating around the wing shaft.

[0028] A further beneficial effect of this utility model is that by designing the wings to be unlockable and rotatable, the wing can be transformed from an outward-spreading posture to a state parallel to both sides of the frame, which can clearly show the actual volume of the wing.

[0029] Furthermore, the wing locking component includes a locking component body and a return spring. The mounting end of the wing has an arc surface adapted to its rotation direction and extends outward to form a locking block. The locking component body is rotatably connected to the wing clamp plate and has an arc-shaped groove adapted to the shape of the mounting end of the wing, and a slot is provided corresponding to the locking block. The end of the locking component body away from its rotation axis is connected to the frame through the return spring. The locking component body rotates away from the wing to complete the unlocking.

[0030] A further beneficial effect of this utility model is that it specifically defines the structure of the wing locking assembly, which is simple in structure and easy to operate. The wing can only be locked by the cooperation of the locking block at the wing mounting end and the locking body.

[0031] Furthermore, the wing is a retractable structure.

[0032] A further beneficial effect of this invention is that it further enhances the practicality of the wing, and the foldable wing allows the length of the wing to be adjusted according to the user's actual needs. Attached Figure Description

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] like Figures 1-7 The present invention provides a rotor structure 1, which can be applied to a drone and installed at the end of the drone wing.

[0053] This rotor structure 1 includes a drive motor 110 for providing power, and a mounting base 120 for mounting and rotating the blades 130. The bottom of the mounting base 120 passes through the motor shaft of the drive motor 110 and rotates together with the motor shaft. The blades 130 are a pair, each a single-bladed blade, with one end along its length serving as its mounting end. The mounting ends of the two blades 130 are symmetrically arranged on both sides of the rotation axis of the mounting base 120, ideally collinear. Their mounting ends are rotatably connected to the mounting base 120 via rotating shafts. The axes of these two rotating shafts are aligned with the axis of the motor shaft of the drive motor 110. In the parallel state, that is, when the drive motor 110 is started, the two blades 130 driven by the mounting base 120 can rotate synchronously around the motor shaft. The two blades 130 can also rotate independently around the shaft of their own mounting ends, and these rotations are all in the same plane. The advantage of this design is that it gives the blades 130 more degrees of freedom. When not in the starting state, the two blades 130 can be brought closer to each other to achieve a folded state. At this time, the two blades 130 can be collinear with the wing 3 and achieve a spatial overlap effect. Therefore, the blades 130 of this rotor structure 1 can occupy less space in the non-starting state, making them easier to store.

[0054] When the blade 130 is in the activating state, it needs to remain relatively stationary with respect to the mounting base 120 to facilitate being driven by the mounting base 120. Ideally, the two blades 130 should be aligned in a straight line, with their ends far apart, as shown in the figure. This state is defined as the unfolded state of the blade 130. To maintain the unfolded state of the blade 130, a blade locking assembly 140 is provided to fix the blade 130 and the mounting base 120. A positioning plate 131 is provided at the mounting end of each blade 130. Specifically, the positioning plate 131 extends outward from the mounting end of the blade 130 along the radial direction of its rotation axis. A through positioning hole 132 is opened on the plate surface of 1. The positioning plates 131 of the two blades 130 have a certain height difference. The height difference refers to the staggered arrangement of the two positioning plates 131 along the axial direction of the rotating shaft. With the above arrangement, when the two blades 130 are in the same straight line, the two positioning plates 131 can fit together and overlap, and the positioning holes 132 on them coincide. The blade locking assembly 140 is installed on the mounting base 120. It has a telescopic locking rod 144. When the blade 130 is in the unfolded state, the locking rod 144 can pass through the positioning holes 132 on the two positioning plates 131 in sequence to lock the blade 130 in the unfolded state.

[0055] Therefore, the rotor structure 1 provided by this utility model, through the cooperation of the blades 130 and the blade locking assembly 140, allows the blades 130 of the rotor structure 1 to freely unfold and retract. When flight is required, the two blades 130 are moved to be in the same straight line, and then the locking rod 144 is used to pass through the positioning hole 132 at the mounting end of the two blades 130 to complete the locking, limiting the two blades 130 to the unfolded state. When the drone needs to be stored, the locking effect between the locking rod 144 and the blades 130 is released, allowing the blades 130 to enter the retracted state, thereby reducing the actual wingspan of the wing and facilitating storage.

[0056] In a more optimized embodiment of this utility model, the mounting base 120 consists of two parts, including a base 121 and a cover 122. The base 121 is approximately a rectangular plate, with both ends of its length slightly adapted to the shape of the mounting end of the blade 130. The center of its lower plate surface is fixedly connected to the motor shaft of the drive motor 110. The cover 122 is mounted on the upper end surface of the base 121, with space between the two. The blade 130 is located between the base 121 and the cover 122, and is rotatably connected to the upper end surface of the base 121 via a rotating shaft, and rotatably abuts against the lower end surface of the cover 122.

[0057] In an optimized embodiment of this invention, the blade 130 is installed by setting a base 121 and a pressure cover 122. The pressure cover 122 rotates and abuts against the mounting end of the blade 130, which can effectively prevent the blade 130 from falling off during high-speed rotation.

[0058] In a more optimized embodiment of this utility model, an elastic limiting block 1221 is provided on the lower end face of the pressure cap 122, corresponding to the mounting end of the blade 130, protruding outward toward the blade 130. The elastic limiting block 1221 can be a structure with its own elasticity, such as a rubber block, or it can be a structure installed on the lower end face of the pressure cap 122 using other elastic elements such as elastic strips or springs. Since the pressure cap 122 and the mounting end of the blade 130 have a rotational abutment relationship, the elastic limiting block 1221 is in a compressed state, and its elastic potential energy has a tendency to be released toward the mounting end of the blade 130. Therefore, on the mounting end of the blade 130, respectively... The blade 130 is provided with an unfolding position limiting groove 133 and a retracting position limiting groove 134. The unfolding position limiting groove 133 is a groove opened on the upper end face of the blade 130 when it is in the unfolded state, corresponding to the position of the elastic limiting block 1221. Similarly, the retracting position limiting groove 134 is a groove opened on the upper end face of the blade 130 when it is in the retracted state, corresponding to the position of the elastic limiting block 1221. When the blade 130 rotates to the unfolded state or the retracted state, the elastic limiting block 1221 enters the corresponding groove under the action of elastic potential energy and engages with the corresponding groove to limit the rotation of the blade 130 relative to the axis of rotation. It is worth noting that the elastic potential energy of the elastic limiting block 1221 in this embodiment is relatively small. The state formed by it and the limiting groove is only a limiting state, not a locked state. The limiting state can be released by simply rotating the blade 130 manually, and the blade 130 can continue to rotate. This technical feature mainly plays two roles: first, when the blade 130 is rotated to the unfolded position, it is pre-locked to prevent the alignment of the two positioning holes 132 from being changed by slight shaking, so that the locking rod 144 of the blade 130 locking mechanism can be inserted into the positioning hole 132 later; second, when the blade 130 is rotated to the retracted position, it is limited to prevent the blade 130 from rotating due to non-human factors.

[0059] In a more optimized embodiment of this utility model, the groove walls of the unfolded position limiting groove 133 and the retracted position limiting groove 134 are slopes that can guide the elastic limiting block 1221 in and out. Under the action of the slope, the elastic limiting block 1221 can be more easily released from the state of being stuck in the limiting groove by human force, and the entry speed of the elastic limiting block 1221 can also be slowed down when it enters the limiting groove, preventing the elastic limiting block 1221 from directly jumping into the limiting groove under the action of elastic potential energy and generating an impact.

[0060] In a more optimized embodiment of this utility model, each blade 130 has two unfolded limiting grooves 133 and two retracted limiting grooves 134 on its mounting end. Each set of unfolded limiting grooves 133 and retracted limiting grooves 134 are arranged opposite to each other, and each blade 130 has two corresponding elastic limiting blocks 1221. Specifically, since the unfolded state and the retracted state of the blade 130 are related by a 90-degree rotation, the unfolded limiting grooves 133 and the retracted limiting grooves 134 are also related by a 90-degree angle. Therefore, the line connecting the two unfolded limiting grooves 133 in each set and the line connecting the two retracted limiting grooves 134 in each set are perpendicular to each other. In this way, whenever the blade 130 rotates 90 degrees, there is a limiting groove that cooperates with the elastic limiting block 1221.

[0061] In a more optimized embodiment of this utility model, the blade locking assembly 140 further includes a pull rod 141, an abutment plate 142, and a drive spring 143. The pull rod 141 passes vertically through the pressure cover 122 and is slidably connected to it. The upper end of the pull rod 141 is its operating end and is fixedly connected to a handle. The handle facilitates user operation and also serves as a limit to prevent the pull rod 141 from completely passing through the pressure cover 122. The lower end of the pull rod 141 is fixedly connected to the abutment plate 142, that is, the abutment plate 142 is located between the pressure cover 122 and the base 121, more specifically, above the two positioning plates 131. The drive spring 143 is located between the pressure cover 122 and the abutment plate 142, and its two ends are respectively connected to the lower end face of the pressure cover 122 and the upper end face of the abutment plate 142. The locking rod 144 is fixedly connected to the lower end face of the pressure cover 122 and the upper end face of the abutment plate 142. The drive spring 143 is fixedly connected to the lower end face of the abutment plate 142. The drive spring 143 is in a compressed state, that is, the drive spring 143 has the tendency to cause the abutment plate 142 to move the locking rod 144 towards the base support 121 and abut against the base support 121. Pulling the pull rod 141 upward can further overcome the elastic potential energy and move the abutment plate 142 and the locking rod 144 away from the base support 121. When the blade 130 rotates to the unfolded position, the positioning hole 132 on the positioning plate 131 is aligned with the locking rod 144. Therefore, when it is necessary to lock the blade 130 to the unfolded position, first pull the pull rod 141 upward, then rotate the blade 130 to the locked position, and finally release the pull rod 141 so that the locking rod 144 passes through the positioning hole 132 under the action of gravity and elastic potential energy, thus completing the locking.

[0062] This utility model also provides a drone, including a frame 2, multiple wings 3, multiple rotor structures 1 corresponding to the number of wings 3, and landing gear. The multiple wings 3 are evenly arranged around the frame 2 and installed on the frame 2. A drive motor 110 is installed at the end of the wing 3 away from the frame 2. The landing gear is installed below the frame 2.

[0063] like Figure 8-11As shown, in this embodiment, four wings 3 are installed on the outer periphery of the frame 2. The ends of the wings 3 are cylindrical in shape adapted to the drive motor 110. The housing of the drive motor 110 is fixedly installed on the ends of the wings 3. It should be noted that the main improvement of this utility model is in the mechanical structure. Other aspects related to electric drive and control systems in the field of UAVs are not improved and are all completed using conventional technical means in this field. They are not closely related to the embodiments described below. Therefore, the accompanying drawings do not show internal parts of the UAV such as motors, chips, wires, and other electrically powered structures, or other structures that should or may appear in other UAVs. The specification of this utility model will not involve electrical connections and electrical control related to the operation of the UAV. This part belongs to common knowledge technology, and those skilled in the art can complete the manufacturing of the whole machine based on known technical means. It will not be described in detail here.

[0064] In a more optimized embodiment of this utility model, the wing 3 can also be folded, which is achieved by the wing shaft 4 and the wing locking member 5. The wing clamp 210 is arranged vertically and parallel to each other on the side of the frame 2. The wing shaft 4 is vertically connected between the wing clamp 210. The mounting end of the wing 3 is similar to its end and is also cylindrical. The wing shaft 4 is coaxial and rotatably connected. Therefore, the drone provided by this utility model is a folding drone. By folding the drone's wing 3 to the side parallel to the frame 2, the volume of the drone in the non-operational state can be effectively reduced. However, in the operation state of the drone, it is necessary to ensure the stable connection between the wing 3 and the frame 2. Therefore, the wing locking member 5 is provided. The wing locking member 5 is rotatably mounted on the wing clamp 210. Its locking end can be close to or away from the mounting end of the wing 3, and cooperate with the mounting end of the wing 3 to lock and prevent the wing 3 from rotating around the wing 3 axis.

[0065] In a more optimized embodiment of this utility model, the wing locking member 5 includes a locking member body 511 and a return spring 520. The mounting end of the wing 3 is cylindrical with an arc surface adapted to its rotation direction, and a locking block 310 extends outward in the radial direction. The locking member body 511 is rotatably connected to the wing clamp 210, and has an arc-shaped groove adapted to the shape of the mounting end of the wing 3. A locking groove 511 is provided on the groove surface corresponding to the locking block 310. One end of the locking member body 511 away from its rotation axis is open to the air intake. The return spring 520 is connected to the frame 2. The return spring 520 is also in a compressed state. It tends to drive the locking body 511 towards the mounting end of the wing 3. When the wing 3 is in the deployed state, the locking block 310 and the locking groove 511 are aligned and locked. At this time, the wing 3 cannot rotate around the wing axis 4. When unlocking is required, the elastic potential energy of the return spring 520 is overcome to make the locking body 511 rotate away from the wing 3. The locking block 310 and the locking groove 511 are separated to achieve unlocking.

[0066] Specifically, for ease of operation, the locking body 511 has a protruding structure near the end of the return spring 520, and a clearance groove is provided on the upper housing of the frame 2. The protruding structure extends out of the clearance groove to form an automatically reset switch for easy operation.

[0067] In a more optimized embodiment of this utility model, the wing 3 is a retractable structure, specifically retracting along its own length, which further improves the practical effect of the wing 3 and allows the length of the wing 3 to be adjusted according to the actual needs of the user.

[0068] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
