The card is connected to the rotating shaft, and its periphery has at least two latching slots that engage with the rotor. The rotating shaft drives the card to rotate, thereby driving the rotor to adjust the rotation angle of the rotor. The card's latching slot engages with the latch.

DETAILED DESCRIPTION

[0105] In the related art, a rotating shaft drives the card to rotate, enabling the switching of different engaging slots, which in turn drive the rotor to rotate. The engaging slots engage with the engaging member to stop the card from rotating, thereby stopping the rotation of the rotor and locking it. However, cards with at least two engaging slots have low structural strength and perform both transmission and locking functions. After long-term use, the cards are easily damaged and require frequent replacement.

[0106] Secondly, during the card assembly process, on the one hand, the concentricity of the card and the motor must be ensured to prevent the card from rotating off the axis; on the other hand, the alignment accuracy of the card's snap-in slot and the rotor or snap-in component must be ensured to ensure locking accuracy. Therefore, the connection method of the above structure is relatively complex and requires high assembly precision, which cannot meet the user's requirements for a simple connection structure with low assembly difficulty for the rotor rotating structure.

[0107] Based on the above technical problems, an embodiment of the present application provides a rotor rotating device and an aircraft, in which the driving device of the rotor rotating device can drive the rotor to rotate to switch the position of the rotor and realize the switching of the rotor between different working states; the locking device of the rotor rotating device can lock the rotating part and the fixed part to lock the position of the rotor, thereby ensuring that the rotor can maintain different working states, can remain stable in different working states, and improve safety and reliability; the rotating part and the fixed part can be linked by different locking parts of the locking device, that is, the rotating part and the fixed part can be locked by two independent structures, the locking device has a high service life, and the assembly requirements between the locking device and the driving device are low, which can meet the user's requirements for low assembly difficulty and simple connection structure of the rotor rotating structure.

[0108] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar devices or devices with the same or similar functions. The described embodiments are embodiments of a part of the devices of the present application, rather than embodiments of the entire device. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0109] First, refer to the attached Figure 1As shown, an embodiment of the present application provides an aircraft 10. The aircraft in the embodiment of the present application can be a micro drone, a light drone, a medium drone, a large drone, or a drone model, or can be an airplane with rotors, a helicopter, etc. This embodiment of the present application does not specifically limit this.

[0110] The following description will be made by taking the aircraft 10 as a drone as an example. The drone of the embodiment of the present application can be controlled by remote control technology to achieve functions such as take-off, landing, or aerial cruising.

[0111] Specifically, the aircraft 10 includes a body 30 , a rotor 100 and a rotor rotating device 20 . The rotating member 210 of the rotor rotating device 20 is connected to the rotor 100 for adjusting the rotation position of the rotor 100 . The rotor rotating device 20 and the rotor 100 are both arranged on the body 30 .

[0112] It is understood that rotor 100 may include propeller 110 and rotating shaft 120. One end of rotating shaft 120 may be connected to rotating member 210 of rotor rotating device 20, and the other end of rotating shaft 120 may be connected to propeller 110. Rotating axis A of rotating shaft 120 is intersecting with rotating axis A of rotating member 210 of rotor rotating device 20. In this way, when rotating member 210 of rotor rotating device 20 rotates, rotating shaft 120 may rotate relative to rotating axis A of rotating member 210, thereby adjusting the position of propeller 110.

[0113] It should be noted that the number of propellers 110 can be arbitrary. For example, the number of propellers 110 can be one, two, three, four, etc. The embodiment of the present application does not limit the specific number of propellers 110, nor is it limited to the above examples.

[0114] The following description will be made by taking three propellers 110 as an example, wherein the three propellers 110 may be arranged at intervals at the ends of the rotating shaft 120 .

[0115] It is understood that the aircraft 10 may be provided with at least two rotors 100. Accordingly, the number of rotor rotating devices 20 may also be at least two, and the at least two rotors 100 may correspond one to one with the at least two rotor rotating devices 20. Furthermore, the at least two rotor rotating devices 20 may operate synchronously or independently, and this may be adjusted according to actual circumstances, which will not be elaborated here.

[0116] For example, the number of rotors 100 may be two, three, four, five, six, etc. The present embodiment of the present application does not limit the specific number of rotors 100, nor is it limited to the above examples. The following description takes the number of rotors as two or four as an example.

[0117] Refer to the attached Figure 13 -Attached Figure 16 As shown, the fuselage 30 may further include a fuselage 32. The fuselage 32 includes a nose 33 and a tail 34. The wing 31 is connected to the fuselage 32. In some embodiments, the connection between the wing 31 and the fuselage 32 is located between the nose 33 and the tail 34. For example, the wing 31 is connected to the top of the fuselage 32. The length direction of the wing 31 is the extension direction of the wing 31. Along the length direction of the wing 31, the wing 31 has an end away from the fuselage 32. The end of the wing 31 is in a free state. The end of the wing 31 may be a wingtip of the wing 31.

[0118] In some embodiments, the wing 31 is a fixed wing, that is, after the wing 31 is connected to the fuselage 32, the position of the wing 31 is fixed and will not change relative to the fuselage 32. For example, the wing 31 will not rotate or pitch. Wings 31 are respectively provided on both sides of the fuselage 32. The wings 31 on both sides of the fuselage 32 can be symmetrically arranged. For example, one wing 31 is provided on one side of the fuselage 32 and one wing 31 is provided on the other side. The embodiment of the present application does not specifically limit the number of wings 31. For example, the wing 31 can be a strip-shaped structural member. The length of the wing 31 is greater than the width of the wing 31. In the embodiment of the present application, wings 31 are respectively provided on both sides of the fuselage 32. A rotor 100 and a rotor rotating device 20 are respectively provided at the ends of the two wings 31.

[0119] Refer to the attached Figure 13 -Attached Figure 16 As shown, the fuselage 30 may further include a connecting rod 35. The connecting rod 35 is connected to the wing 31. The connecting rod 35 itself is relatively small, providing a relatively small windward surface, thereby reducing the drag of the aircraft 10, improving the endurance of the aircraft 10, or increasing the maximum cruising speed of the aircraft 10. The connecting rod 35 itself is relatively light, which helps reduce the total weight of the aircraft 10 and improve the endurance of the aircraft 10.

[0120] In some embodiments, connecting rod 35 can be a straight rod. The axial direction of connecting rod 35 is aligned with the width direction of wing 31, so that connecting rod 35 has a relatively small windward surface. Fixed rotor 40 can be mounted on connecting rod 35. Fixed rotor 40 can have the same structure as rotor 100, including a propeller and a rotating shaft, or it can be different, such as having a different number of propellers.

[0121] In some embodiments, referring to the Figure 13 -Attached Figure 14 As shown, the rotor 100 can be provided at only one end of the connecting rod 35, and the fixed rotor 40 can be provided at the other end; Figure 15 -Attached Figure 16As shown, the rotors 100 may not be disposed at the opposite ends of the connecting rod 35 . In this case, the fixed rotors 40 are respectively disposed at the opposite ends of the connecting rod 35 .

[0122] The fuselage 30 of the present embodiment may further include landing gear 36. Landing gear 36 is disposed on the fuselage 32. The landing gear 36 provides support for the aircraft 10 during takeoff or landing. During landing, the landing gear 36 provides a cushioning effect, reducing the possibility of damage to the fuselage 32 caused by impact.

[0123] Secondly, refer to the attached Figure 2 -Attached Figure 12 As shown, the embodiment of the present application further provides a rotor rotating device 20 for driving the rotor 100 to rotate. The rotor rotating device 20 includes a driving device 200 and a locking device 300.

[0124] Specifically, refer to the attached Figure 3 -Attached Figure 6 As shown, the driving device 200 includes a rotating member 210 and a fixed member 220 that can rotate relative to each other. The rotating member 210 is used to connect with the rotor 100 to drive the rotor 100 to rotate. The rotating member 210 can rotate relative to the fixed member 220, so that the rotor 100 can rotate relative to the fixed member 220.

[0125] It is understood that drive device 200 can be an electric motor, which includes a stator and a rotor that rotate relative to each other. The rotor is the output end, namely, the rotating member 210 in the embodiment of the present application; the stator is the fixed end, namely, the fixed member 220 in the embodiment of the present application. Rotor 100 can be connected to rotating member 210 of drive device 200, namely, to the rotor of the motor. In this way, rotor 100 can rotate relative to the stator under the drive of the rotor, thereby allowing rotor 100 to switch positions and switch to different operating states.

[0126] It should be noted that different working states may refer to different angles between the rotor 100 and the fixing member 220. Different positions of the rotor 100 may result in different flight states. For example, when the rotating shaft 120 of the rotor 100 is arranged vertically, refer to the attached FIG. Figure 14 and attached Figure 16 As shown, the rotor 100 can be directed upwards; of course, the rotor 100 can also be directed downwards; when the rotation axis 120 of the rotor 100 is horizontally arranged, the rotor 100 can be directed backwards. Figure 13 and attached Figure 15 As shown, the rotor 100 can also fly forward; when the rotation axis 120 of the rotor 100 is tilted, the rotor 100 can be used to assist the current flight direction or maintain the flight altitude, etc.

[0127] The embodiments of the present application do not limit the different working states of the rotor 100 and are not limited to the above examples.

[0128] Furthermore, the locking device 300 includes a first locking member 310 and a second locking member 320 that cooperate with each other. The first locking member 310 is linked to the fixing member 220 , and the second locking member 320 is linked to the rotating member 210 .

[0129] It is understood that the cooperation between the first locking member 310 and the second locking member 320 may mean that the first locking member 310 and the second locking member 320 can have different states, so that the fixed member 220 and the rotating member 210 can switch between a locked state and an unlocked state. The locked state may mean that the first locking member 310 and the second locking member 320 are locked to each other, and the fixed member 220 and the rotating member 210 are locked to each other; the unlocked state may mean that the first locking member 310 and the second locking member 320 are not locked, and the fixed member 220 and the rotating member 210 are not locked. When the fixed member 220 and the rotating member 210 are not locked, the rotating member 210 and the fixed member 220 can be in a state of relative rotation or stationary, such as in an unlocked state.

[0130] The following description will be made by taking as an example the case where the first locking member 310 and the second locking member 320 are not locked and the fixing member 220 and the rotating member 210 are rotating relative to each other.

[0131] It should be noted that the linkage can be direct or indirect. That is, the first locking member 310 can be directly or indirectly connected to the fixed member 220; the second locking member 320 can be directly or indirectly connected to the rotating member 210. Direct connection refers to direct contact and connection, while indirect connection refers to indirect contact through other structures to form a connection.

[0132] The embodiment of the present application does not limit the specific connection method between the first locking member 310 and the fixing member 220 and between the second locking member 320 and the rotating member 210, nor is it limited to the above examples.

[0133] It can be understood that through the above-mentioned arrangement, the driving device 200 can drive the rotor 100 to rotate so as to switch the position of the rotor 100 and realize the switching of the rotor 100 between different working states; the locking device 300 can lock the rotating part 210 and the fixed part 220 to lock the position of the rotor 100, thereby ensuring that the rotor 100 can maintain different working states, can remain stable in different working states, and improve safety and reliability.

[0134] Furthermore, through the above-mentioned arrangement, the rotating part 210 and the fixed part 220 can be locked through two independent structures, the service life of the locking device 300 is relatively high, and the assembly requirements between the locking device 300 and the driving device 200 are relatively low, which can meet the user's requirements for low assembly difficulty and simple connection structure of the rotor 100 rotating structure.

[0135] As an optional embodiment, refer to the attached Figure 3 -Attached Figure 6 As shown, the fixed member 220 is sleeved around the outer periphery of the rotating member 210. Thus, the rotating member 210 can be an annular or circular columnar structure, and the fixed member 220 can be an annular columnar structure, sleeved around the outer periphery of the rotating member 210. This arrangement provides a high degree of concentricity between the fixed member 220 and the rotating member 210, thereby improving the rotational accuracy of the rotor 100 relative to the fixed member 220 and, consequently, the positioning accuracy of the rotor 100.

[0136] As another optional embodiment, rotating member 210 is sleeved around the outer periphery of fixed member 220 (not shown). Thus, fixed member 220 can be an annular or circular columnar structure, and rotating member 210 can be an annular columnar structure, with rotating member 210 sleeved around the outer periphery of fixed member 220. This arrangement provides a high degree of concentricity between fixed member 220 and rotating member 210, thereby improving the rotational accuracy of rotor 100 relative to fixed member 220 and, consequently, the positioning accuracy of rotor 100.

[0137] The following description will be made by taking an example where the fixing member 220 is sleeved on the outer periphery of the rotating member 210 .

[0138] As an optional embodiment, the rotatable angle of the rotating member 210 relative to the fixed member 220 is 100°. That is, through the configuration of the first locking member 310 and the second locking member 320, the rotating member 210 can drive the rotor 100 to rotate relative to the fixed member 220, and the maximum rotation angle is 100°. For example, the rotation angle can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, etc. The embodiments of the present application do not limit the specific rotation angle of the rotating member 210 relative to the fixed member 220, nor are they limited to the above examples.

[0139] Through the above arrangement, the rotating member 210 can drive the rotor 100 to rotate up to 100° relative to the fixed member 220 to switch the position of the rotor 100 and realize the switching of the rotor 100 between different working states.

[0140] As an optional embodiment, the extension direction of the rotation axis A of the rotating member 210 is defined as the horizontal direction X, that is, the length direction is the same as the horizontal direction X. The range of the rotation angle of the rotating member 210 relative to the fixed member 220 is -5°-95°. Among them, since the rotation axis A is the horizontal direction X, according to the coordinate system, the vertical direction Y (i.e., the vertical direction Y) is the vertical direction Y. Figure 13 -Attached Figure 16 There is an intersection between the Y in the vertical direction (shown in the figure) and the horizontal direction X. Relative to the horizontal direction X, the positive direction in the vertical direction Y (i.e., the positive direction in the vertical direction Y) Figure 13 -Attached Figure 16 The +Y in the figure is the upward direction of the horizontal direction X, and the negative direction in the vertical direction Y (i.e. the negative direction in the figure 13- Figure 16 The -Y) shown in the figure is the bottom of the horizontal direction X.

[0141] On this basis, the angle should be between -180° and +180°. It should be noted that the vertical direction Y can be positive or negative. In the embodiment of the present application, when the rotating member 210 drives the rotor 100 to rotate between -5° and 0°, the rotation axis of the rotor 100 is located below the rotation axis A. When the rotating member 210 drives the rotor 100 to rotate between 0° and 90°, the rotor 100 is located above the rotation axis A.

[0142] Through the above arrangement, the rotating member 210 can drive the rotor 100 to rotate relative to the fixed member 220, and the rotation angle range is -5°-95°, so as to switch the position of the rotor 100 and realize the switching of the rotor 100 between different working states.

[0143] As an optional embodiment, the drive device 200 has a wire channel extending along the axis of rotation A of the rotating member 210. The wire channel can be used to thread wires. The wire channel can be located on the fixed member 220 of the drive device 200 or on the rotating member 210 of the drive device. The specific location of the wire channel is not limited to the above examples in this embodiment.

[0144] It should be noted that to prevent bending of the wire, the wire guide channel can be provided close to the rotation axis A of the rotating member 210 in the driving device 200. In the embodiment of the present application, when the fixing member 220 is sleeved on the outer periphery of the rotating member 210, the wire guide channel can be provided at the center axis of the rotating member 210. In other words, the rotating member 210 can be shaped like an annular columnar structure.

[0145] Through the above arrangement, the guide channel can be used to guide and protect the wire to prevent the wire from bending during rotation, thereby increasing the service life of the wire.

[0146] As another optional embodiment, plug connectors (not shown in the figure) that are electrically connected to each other are respectively provided at two opposite ends of the driving device 200.

[0147] It is understood that the plug connector can be installed on the rotating member 210 or the fixed member 220. The present embodiment does not limit the installation location of the plug connector, nor is it limited to the above example. The number of plug connectors can be at least two, and the at least two plug connectors can be distributed in a circular shape on the rotating member 210 or the fixed member 220.

[0148] Through the above arrangement, the plug connector can be used for electrical connection, and the wire does not need to be wound around the drive device 200, which can reduce the space occupied by the wire, avoid bending of the wire, and improve the service life of the wire.

[0149] As an optional embodiment, the drive device 200 is a harmonic reduction motor. The structure of the harmonic reduction motor is relatively simple and easy to assemble. In addition, the harmonic reduction motor is small in size and has a low weight, which facilitates the miniaturization and lightweighting of the aircraft 10. Secondly, the harmonic reduction motor has speed measurement and rotation angle feedback, and has a high system integration and high reliability. Finally, the harmonic reduction motor has a large transmission ratio range, high load capacity, transmission accuracy, and transmission efficiency, which is conducive to ensuring the rotation accuracy and structural performance of the drive device 200, and thus ensuring the rotation accuracy and rotation efficiency of the rotor rotating device 20.

[0150] As an optional embodiment, refer to the attached Figure 3 As shown, the first locking member 310 is disposed on the fixed member 220, and the second locking member 320 is disposed on the rotating member 210. That is, the locking device 300 is directly disposed on the driving device 200.

[0151] Specifically, when the fixed member 220 is sleeved on the outer periphery of the rotating member 210, the first locking member 310 and the second locking member 320 can both be located between the fixed member 220 and the rotating member 210. The first locking member 310 is disposed on the fixed member 220, and the second locking member 320 is disposed on the driving device 200.

[0152] Through the above arrangement, locking device 300 can quickly lock rotating member 210 and fixed member 220 to lock the position of rotor 100, thereby ensuring that rotor 100 can maintain different operating states and maintain stability in different operating states, thereby improving safety and reliability. In addition, rotating member 210 and fixed member 220 can be locked by two independent structures, which increases the service life of locking device 300 and reduces the assembly requirements between locking device 300 and drive device 200, meeting user requirements for low-efficiency assembly and simple connection structure of the rotating structure of rotor 100.

[0153] As an optional embodiment, refer to the attached Figure 3 -Attached Figure 12 As shown, there are two first locking members 310 and one second locking member 320. Along the rotational direction of the rotating member 210, one second locking member 320 is located between the two first locking members 310. In this way, the two first locking members 310 can form a rotatable region with a certain angle restriction. When the second locking member 320 is located between the two first locking members 310, the second locking member 320 can only rotate within the rotatable region, allowing the rotating member 210 to rotate within a preset angle, thereby achieving precise control of the position of the rotor 100.

[0154] As another optional embodiment, there is one first locking member 310 and two second locking members 320, and along the rotation direction of the rotating member 210, one first locking member 310 is located between two second locking members 320. In this way, the two second locking members 320 can form a rotatable area with corresponding angle restrictions. When the first locking member 310 is located between the two second locking members 320, the first locking member 310 can only rotate within the rotatable area, allowing the rotating member 210 to rotate within a preset angle, thereby achieving precise control of the position of the rotor 100.

[0155] The following description will be made by taking an example where the number of the first locking members 310 is two and the number of the second locking member 320 is one.

[0156] In some specific implementations, when the first locking member 310 is disposed on the fixed member 220 and the second locking member 320 is disposed on the rotating member 210, the first locking member 310 and the second locking member 320 can both be protrusions, with the two first locking members 310 spaced apart on the fixed member 220. The second locking member 320 can move between the two first locking members 310 to lock the locking device 300 to the drive device 200 and thereby lock the position of the rotor 100. This ensures that the rotor 100 can maintain different operating states and remain stable in different operating states, thereby improving safety and reliability. In addition, the rotating member 210 and the fixed member 220 can be locked by two independent structures, which increases the service life of the locking device 300 and reduces the assembly requirements between the locking device 300 and the drive device 200, thereby meeting the user's requirements for a simple connection structure with low assembly difficulty for the rotating structure of the rotor 100.

[0157] As an optional embodiment, the first locking member 310 is one of the clamping column and the clamping plate, and the second locking member 320 is the other of the clamping column and the clamping plate, and the clamping column and the clamping plate are located on each other's rotation path.

[0158] For example, when the first locking member 310 is a clamping column and the second locking member 320 is a clamping plate, the clamping column can be directly or indirectly set on the fixed member 220, and the clamping plate can be linked with the rotating member 210, that is, when the rotating member 210 rotates, the clamping plate can rotate synchronously, and the clamping plate contacts the clamping column, thereby completing the locking of the driving device 200 by the locking device 300.

[0159] Another example is that when the first locking member 310 is a clamping plate and the second locking member 320 is a clamping column, the clamping column can be linked with the rotating member 210, and the clamping plate can be directly or indirectly set on the fixed member 220, that is, when the rotating member 210 rotates, the clamping column can rotate synchronously, and the clamping plate contacts the clamping column, thereby completing the locking of the driving device 200 by the locking device 300.

[0160] Refer to the attached Figure 6 -Attached Figure 12 As shown, the following description is made by taking the first locking member 310 as a clamping plate and the second locking member 320 as a clamping column as an example, that is, the locking device 300 includes two clamping plates and one clamping column.

[0161] It should be noted that both clamping plates can rotate about the rotation axis A of the rotating member 210. The area between the two clamping plates is the rotatable area. For example, the rotatable area is fan-shaped or semicircular. It is understood that the user can adjust the angle between the two clamping plates to adjust the size of the rotatable area, that is, control the maximum rotation angle of the rotor 100.

[0162] It can be understood that the two clamping plates can be two independent structures, such as the two clamping plates can be interconnected and linked to different positions of the fixed part 220; the two clamping plates can also be an integral part, such as one end of the two clamping plates is connected to each other and linked to the rotation axis A of the rotating part 210 corresponding to the fixed part 220.

[0163] Among them, the specific structure of the two clip-on plates can be adjusted according to actual conditions. In the embodiment of the present application, the two clip-on plates are an integrated piece.

[0164] For example, the angle between the two clamping plates can be an acute angle, a right angle, or an obtuse angle depending on the actual situation. The embodiment of the present application does not limit the specific angle between the two clamping plates, nor is it limited to the above examples.

[0165] The following description will be made by taking an example where the angle between the two clamping plates is 90°, that is, the rotor 100 can rotate a maximum of 90°.

[0166] Furthermore, in order to ensure the clamping stability between the clamping plate and the clamping column, the clamping plate can have a groove corresponding to the clamping column. When the clamping plate contacts the clamping column, the clamping column can be located in the groove, and the outer wall surface of the clamping column abuts against the groove wall of the groove.

[0167] It should be noted that the shape of the clamping post is adapted to the shape of the recess of the clamping plate. For example, the clamping post is a circular cylinder, and the recess of the clamping plate is a circular recess with a notch, so that the clamping post can enter or move out of the circular recess through the notch. For another example, the clamping post is a square cylinder, and the recess of the clamping plate is a triangular recess or a rectangular recess. The embodiments of this application do not limit the specific shapes of the clamping post and the recess of the clamping plate, nor are they limited to the above examples.

[0168] The following description will be made by taking as an example an example that the groove of the clamping plate is a circular groove with a notch so that the clamping post can enter or move out of the circular groove through the notch.

[0169] Through the above arrangement, the clamping post can be engaged with the clamping plate, thereby locking the locking device to the drive device 200 and locking the position of the rotor 100. This ensures that the rotor 100 can maintain different operating states and remains stable in different operating states, improving safety and reliability. In addition, the rotating member 210 and the fixed member 220 can be locked by two independent structures, which increases the service life of the locking device 300 and reduces the assembly requirements between the locking device 300 and the drive device 200. This can meet the user's requirements for a simple connection structure with low assembly difficulty for the rotating structure of the rotor 100.

[0170] As an optional embodiment, refer to the attached Figure 2 , Attachment Figure 5 -Attached Figure 12 As shown, the rotor rotating device 20 further includes a first connecting member 400 , one side of the first connecting member 400 is connected to the rotating member 210 , and the other side is used to connect to the rotor 100 .

[0171] It is understood that the first connecting member 400 can be in any form. For example, the first connecting member 400 can be a plate or a column. The present embodiment of the application does not limit the specific structure of the first connecting member 400, nor is it limited to the above example. The following description uses the first connecting member 400 as an example.

[0172] By providing the above-mentioned first connecting member 400, the first connecting member 400 can connect the rotating member 210 and the rotor 100. When the rotating member 210 rotates, the first connecting member 400 can rotate synchronously and drive the rotor 100 to rotate, thereby completing the rotation of the rotor 100.

[0173] It should be noted that when the first connecting member 400 is connected to the rotating member 210 and the rotor 100, in order to ensure the rotational performance of the rotating member 210, the extension direction of the first connecting member 400 can intersect with the rotation axis A of the rotating member 210. The angle between the extension direction of the first connecting member 400 and the rotation axis A of the rotating member 210 can be acute, right, or obtuse. In the embodiment of the present application, the angle between the extension direction of the first connecting member 400 and the rotation axis A of the rotating member 210 is a right angle, that is, the extension direction of the first connecting member 400 is perpendicular to the rotation axis A of the rotating member 210.

[0174] It is understandable that when the rotor rotating device 20 further includes the first connecting member 400, the second locking member 320 may be connected to the first connecting member 400 or may not be connected to the first connecting member 400. The following is a detailed description:

[0175] As an optional embodiment, refer to the attached Figure 10 As shown, when the fixed member 220 is sleeved on the outer periphery of the rotating member 210, the rotating member 210 has a second connecting portion 211, and along the extension direction of the rotation axis A of the rotating member 210, at least part of the second connecting portion 211 protrudes from the fixed member 220; the first connecting member 400 includes a third connecting portion 410 on the side facing the rotating member 210, and the third connecting portion 410 is connected to the second connecting portion 211.

[0176] Specifically, the second connecting portion 211 is located at the end of the rotating member 210 and protrudes from the fixed member 220. It can be connected to the third connecting portion 410, thereby connecting the first connecting member 400 to the rotating member 210. When the rotating member 210 is a circular ring structure, the third connecting portion 410 is also a circular ring structure. In this case, the second connecting portion 211 can be a protrusion.

[0177] Exemplarily, when the first connecting member 400 is sleeved and connected to the rotating member 210, the side wall of the protrusion can be tightly attached to the side wall of the second connecting portion 211, for example, it can form an interference fit with the second connecting portion 211, or be bonded by adhesive, or be connected by screws, rivets and other connecting members. Another exemplary embodiment, when the first connecting member 400 is embedded and connected to the rotating member 210, the second connecting portion 211 can have a groove corresponding to the protrusion, and the protrusion can be located in the groove to form an interference fit with the second connecting portion 211, or be bonded by adhesive, or be connected by screws, rivets and other connecting members. The embodiments of the present application do not limit the specific method of connecting the second connecting portion 211 and the third connecting portion 410, nor are they limited to the above examples.

[0178] The following description will be made by taking the first connecting member 400 being sleeved and connected to the rotating member 210 as an example.

[0179] It should be noted that when the third connecting part 410 of the first connecting member 400 is sleeved and connected to the second connecting part 211 of the rotating member 210, a limiting protrusion and a limiting groove for limiting can be provided between the third connecting part 410 and the second connecting part 211. The limiting protrusion can be provided on the third connecting part 410, and the limiting groove can be provided on the second connecting part 211; or the limiting protrusion can be provided on the second connecting part 211, and the limiting groove can be provided on the third connecting part 410.

[0180] Through the above setting, the first connecting member 400 can be connected to the rotating member 210. When the rotating member 210 rotates, the first connecting member 400 can rotate synchronously to drive the rotor 100 to rotate, so as to switch the position of the rotor 100 and realize the switching of the rotor 100 between different working states.

[0181] As an optional embodiment, refer to the attached Figure 6 , Attachment Figure 7 As shown, the rotor rotating device 20 also includes a limit member 500, the first connecting member 400 has a through hole 420, the through hole 420 passes through the first connecting member 400 along the thickness direction of the first connecting member 400, the limit member 500 is fixedly connected to the first connecting member 400, and the through hole 420 is penetrated to connect with the rotating member 210.

[0182] Through the above setting, the limit member 500 can be used to connect the first connecting member 400 and the rotating member 210, which can enhance the connection strength between the second connecting part 211 and the third connecting part 410, and then enhance the connection strength between the first connecting member 400 and the rotating member 210 to ensure that the rotating member 210 can drive the first connecting member 400 to rotate.

[0183] It should be noted that the limiting member 500 can be connected to the rotating member 210 in any manner, such as forming an interference fit with the rotating member 210, or bonding with adhesive, or connecting with screws, rivets and other connecting members.

[0184] Furthermore, the stopper 500 can also be used to secure wires. It is understood that when the drive device 200 has the aforementioned wire channel or the aforementioned plug connector, the wires can be threaded through the wire channel or positioned between the rotating member 210 and the first connector 400 via the plug connector. In this case, the wires can be threaded through the through-holes 420 of the first connector 400, and the stopper 500 can guide and secure the wires to prevent them from bending, thereby ensuring electrical connectivity within the rotor rotating device 20 and, consequently, the proper operation of the aircraft 10.

[0185] As an optional embodiment, refer to the attached Figure 5As shown, second locking member 320 is connected to first connecting member 400 and is located on the side of first connecting member 400 facing fixed member 220. When rotating member 210 rotates, rotating member 210 can drive first connecting member 400 to rotate, which in turn drives rotor 100 to rotate, completing the rotation of rotor 100. Second locking member 320 can cooperate with first locking member 310 to lock the position of rotor 100, thereby ensuring that rotor 100 can maintain different operating states and remain stable in different operating states, thereby improving safety and reliability.

[0186] Further, as an optional embodiment, refer to the attached Figure 17 As shown, rotor rotating device 20 further includes a sleeve 600, which is sleeved and connected to the outer circumference of fixing member 220, and a first locking member 310 is disposed on sleeve 600. Here, first locking member 310 on sleeve 600 can cooperate with second locking member 320 on first connecting member 400 to lock the position of rotor 100, thereby ensuring that rotor 100 can maintain different operating states and remain stable in different operating states, thereby improving safety and reliability.

[0187] The following description is based on the assumption that the second locking member 320 is not connected to the first connecting member 400 .

[0188] As an optional embodiment, refer to the attached Figure 2 , Attachment Figure 6 -Attached Figure 12 As shown, rotor rotating device 20 also includes a second connector 700, which is movable relative to fixed member 220 and is used to connect to rotor 100. Second locking member 320 is connected to second connector 700. Thus, first connector 400 can be used to drive rotor 100 for rotation, while second connector 700 can be used to lock rotor 100. The first connector 400 and second connector 700 have different functions. Furthermore, rotating member 210 and fixed member 220 can be locked using two independent structures, which increases the service life of locking device 300 and reduces assembly requirements between locking device 300 and drive device 200, meeting user requirements for a simple connection structure with low assembly difficulty for rotor 100's rotating structure.

[0189] In some embodiments, the second connecting member 700 can be connected to the rotating member 210. At this time, when the rotating member 210 rotates, the second connecting member 700 can rotate synchronously. The second locking member 320 located on the second connecting member 700 can cooperate with the first locking member 310 to lock the position of the rotor 100, thereby ensuring that the rotor 100 can maintain different working states, remain stable in different working states, and improve safety and reliability.

[0190] In other embodiments, the second connecting member 700 can also be connected to the first connecting member 400. In this way, when the rotating member 210 rotates, the first connecting member 400 can drive the second connecting member 700 to rotate, and the second locking member 320 located on the second connecting member 700 can cooperate with the first locking member 310 to lock the position of the rotor 100, thereby ensuring that the rotor 100 can maintain different working states, can remain stable in different working states, and improve safety and reliability.

[0191] In some other embodiments, the second connecting member 700 can also be directly connected to the rotor 100, that is, the first connecting member 400 and the second connecting member 700 are both connected to the rotor 100. When the rotating member 210 rotates, the first connecting member 400 can drive the rotor 100 to rotate synchronously, and the second connecting member 700 is driven to rotate. The second locking member 320 located on the second connecting member 700 can cooperate with the first locking member 310 to lock the position of the rotor 100, thereby ensuring that the rotor 100 can maintain different working states, can remain stable in different working states, and improve safety and reliability.

[0192] The following description will be made by taking an example in which the second connecting member 700 can also be directly connected to the rotor 100 .

[0193] It should be noted that along the extension direction of the rotation axis A of the rotating member 210, the first connecting member 400 and the second connecting member 700 are respectively located on opposite sides of the driving device 200, so as to be connected to different positions of the rotor 100. This can improve the connection strength between the rotor rotating device 20 and the rotor 100, thereby enhancing the connection stability of the rotor 100 and further enhancing the flight performance of the aircraft 10. The extension direction of the second connecting member 700 can be parallel to the extension direction of the first connecting member 400, that is, the extension direction of the second connecting member 700 is perpendicular to the direction of the rotation axis A of the rotating member 210.

[0194] Further, as an optional embodiment, refer to the attached Figure 2 , Attachment Figure 6 -Attached Figure 12 As shown, the rotor rotating device 20 also includes a third connecting member 800, which is respectively connected to the first connecting member 400 and the second connecting member 700, and is spaced apart from the driving device 200. The side of the third connecting member 800 facing away from the driving device 200 is used to connect to the rotor 100.

[0195] Specifically, the third connecting member 800 may extend in a direction parallel to the direction of the rotation axis A of the rotating member 210, and its two ends may be connected to the first connecting member 400 and the second connecting member 700, respectively. Thus, when the rotating member 210 rotates, the rotating member 210 can drive the third connecting member 800 to rotate via the first connecting member 400, and the third connecting member 800 can drive the rotor 100 and the second connecting member 700 to rotate, thereby completing the rotation of the rotor 100.

[0196] Through the above-mentioned arrangement, the third connecting member 800 can enhance the connection strength between the rotating member 210 and the rotor 100 to ensure that the rotor 100 can maintain a working state, remain stable in different working states, and improve safety and reliability; in addition, the third connecting member 800, the second connecting member 700 and the first connecting member 400 can form a space for placing the driving device 200, and be directly or indirectly connected to the driving device 200, so that the rotor rotating device 20 has a higher structural strength to complete the rotation of the rotor 100.

[0197] As an optional embodiment, refer to the attached Figure 2 , Attachment Figure 6 -Attached Figure 12 As shown, the rotor rotating device 20 further includes a sleeve 600 , which is sleeved and connected to the outer periphery of the fixing member 220 , the second connecting member 700 is movably connected to the sleeve 600 , and the first locking member 310 is disposed on the sleeve 600 .

[0198] Specifically, when the fixed member 220 is sleeved around the outer periphery of the rotating member 210, the sleeve 600 is sleeved and connected to the outer periphery of the fixed member 220, that is, the rotating member 210 can rotate relative to the fixed member 220 and the sleeve 600. To ensure that the second connecting member 700 can rotate relative to the fixed member 220 and the sleeve 600, the second connecting member 700 can be movably connected to the sleeve 600, that is, the second connecting member 700 can rotate relative to the sleeve 600. In this way, when the rotating member 210 rotates, the rotating member 210 can drive the third connecting member 800 to rotate via the first connecting member 400, and the third connecting member 800 can drive the rotor 100 and the second connecting member 700 to rotate, thereby completing the rotation of the rotor 100.

[0199] Through the above arrangement, the second connecting member 700 is connected to the rotating member 210 via the third connecting member 800 and the first connecting member 400, thereby enhancing the connection strength between the rotating member 210 and the rotor 100, thereby providing the rotor rotating device 20 with a higher structural strength. Furthermore, by disposing the first locking member 310 on the sleeve 600 and the second locking member 320 on the second connecting member 700, the first locking member 310 can approach the second locking member 320 to cooperate and complete the locking, thereby locking the position of the rotor 100. This ensures that the rotor 100 can maintain different operating states and remain stable in different operating states, thereby improving safety and reliability.

[0200] As an optional embodiment, refer to the attached Figure 2 , Attachment Figure 6 -Attached Figure 12 As shown, the sleeve 600 includes a first sleeve 610 and a second sleeve 620. The first sleeve 610 is sleeved and connected to the outer periphery of the fixing member 220, that is, the first sleeve 610 is connected to the fixing member 220. The second sleeve 620 is connected to the first sleeve 610, that is, the second sleeve 620 is connected to the fixing member 220 through the first sleeve 610. The first sleeve 610 and the second sleeve 620 can be independent structures. In this way, the connection between the first sleeve 610 and the fixing member 220 can be completed more simply.

[0201] The second connecting member 700 is movably connected to the second sleeve 620, that is, the second connecting member 700 is movably connected to the fixed member 220 through the second sleeve 620 and the first sleeve 610. In other words, the rotating member 210 is sequentially connected to the second connecting member 700 through the first connecting member 400 and the third connecting member 800, and the fixed member 220 is sequentially movably connected to the second connecting member 700 through the first sleeve 610 and the second sleeve 620.

[0202] The first connecting member 400 is located on the side of the first sleeve 610 facing away from the second sleeve 620, and the first locking member 310 is disposed on the second sleeve 620. With this arrangement, the second locking member 320 is disposed on the second connecting member 700. The first locking member 310 can cooperate with the second locking member 320 to lock the rotating member 210 and the fixed member 220, thereby locking the position of the rotor 100. This ensures that the rotor 100 can maintain different operating states and remain stable in different operating states, thereby improving safety and reliability. Furthermore, with this arrangement, the rotating member 210 and the fixed member 220 can be locked by the first locking member 310 and the second locking member 320 located in different structures. This increases the service life of the locking device 300 and reduces the assembly requirements between the locking device 300 and the drive device 200, meeting user requirements for a simple connection structure with low assembly difficulty for the rotating structure of the rotor 100.

[0203] As an optional embodiment, refer to the attached Figure 10 As shown, the first sleeve 610 is provided with at least two sleeve holes 611 spaced apart from each other.

[0204] It should be noted that the shape of the sleeve hole 611 can be arbitrary. For example, the sleeve hole 611 can be a circular hole, an elliptical hole, a square hole, etc. The embodiments of this application do not limit the specific shape of the sleeve hole 611, nor are they limited to the above examples. The following description uses the sleeve hole 611 as an example.

[0205] Furthermore, the number of the sleeve holes 611 can be arbitrary. For example, the number of the sleeve holes 611 can be two, three, four, five, six, etc. The embodiment of the present application does not limit the specific number of the sleeve holes 611, nor is it limited to the above examples.

[0206] Through the above-mentioned arrangement, the first sleeve 610 can dissipate heat through the sleeve hole 611 to ensure the heat dissipation capacity of the fixed part 220 located in the first sleeve 610 and the rotating part 210 located inside the fixed part 220, thereby ensuring the normal operation of the fixed part 220 and the rotating part 210; in addition, the first sleeve 610 can achieve weight reduction through the sleeve hole 611 to reduce the weight proportion of the first sleeve 610 in the rotor rotating device 20, which is beneficial to improving the lightweight of the rotor rotating device 20 and the aircraft 10.

[0207] As an optional embodiment, refer to the attached Figure 10 As shown, the first sleeve 610 includes an abutment portion 612 on a side away from the second sleeve 620. The abutment portion 612 can be used to connect the first sleeve 610 to the fixing member 220 to increase the contact area between the first sleeve 610 and the fixing member 220, thereby increasing the connection strength between the first sleeve 610 and the fixing member 220, thereby ensuring the connection stability of the rotor rotating device 20.

[0208] It should be noted that the shape of the abutment portion 612 can be arbitrary. For example, the abutment portion 612 can be in the shape of a plate, a column, etc. The embodiments of the present application do not limit the specific shape of the abutment portion 612, nor are they limited to the above examples. The following description takes the abutment portion 612 as an example of a plate.

[0209] When the fixing member 220 is sleeved on the outer periphery of the rotating member 210, in some embodiments, the abutment portion 612 abuts against the side of the fixing member 220 that is closer to the first connecting member 400. In this way, the abutment portion 612 can increase the contact area between the first sleeve 610 and the fixing member 220, thereby improving the connection strength between the first sleeve 610 and the fixing member 220, thereby ensuring the connection stability of the rotor rotating device 20.

[0210] In addition, when the abutment portion 612 abuts against the side of the fixing member 220 close to the first connecting member 400, and the rotating member 210 has a second connecting portion 211 protruding from the fixing member 220, the abutment portion 612 can be located on the side of the second connecting portion 211 away from the first connecting member 400. In this way, the torque of each force-bearing position in the driving device 200 is reduced, so that the driving device 200 has a more balanced force, which is beneficial to ensure the normal operation of the driving device 200 and improve the service life of the driving device 200.

[0211] Furthermore, in some other embodiments, the abutment portion 612 abuts against a side of the fixing member 220 away from the first connector 400. In this way, the abutment portion 612 can increase the contact area between the first sleeve 610 and the fixing member 220, thereby improving the connection strength between the first sleeve 610 and the fixing member 220, thereby ensuring the connection stability of the rotor rotating device 20.

[0212] As an optional embodiment, refer to the attached Figure 2 , Attachment Figure 10 -Attached Figure 12 As shown, the second sleeve 620 includes a docking portion 621 and a sleeve portion 622 connected to each other. The docking portion 621 is located on a side of the sleeve portion 622 close to the first sleeve 610 and is used to connect with the first sleeve 610; the first locking member 310 is sleeved and connected to the sleeve portion 622.

[0213] That is, the docking portion 621 is connected to the first sleeve 610, and the sleeve portion 622 is used to connect to the first locking member 310. That is, the fixing member 220 is movably connected to the second connecting member 700 through the first sleeve 610, the docking portion 621, and the sleeve portion 622 in sequence.

[0214] It should be noted that the docking portion 621 can be connected to the first sleeve 610 in any manner. For example, the docking portion 621 can be adhesively connected to the first sleeve 610, or can be threadedly connected using screws, bolts, or other structures, or can be clamped. The embodiments of this application do not limit the specific connection method between the docking portion 621 and the first sleeve 610, nor are they limited to the above examples. The following description uses the example of a threaded connection between the docking portion 621 and the first sleeve 610.

[0215] It is understandable that the docking portion 621 has at least two threaded holes, and correspondingly, the first sleeve 610 also has at least two threaded holes on a side away from the first connector 400 to facilitate threaded connection through threaded connectors such as bolts or screws.

[0216] Through the above arrangement, the second locking member 320 is disposed on the second connecting member 700, and the first locking member 310 can cooperate with the second locking member 320 to lock the rotating member 210 and the fixed member 220 to lock the position of the rotor 100, thereby ensuring that the rotor 100 can maintain different operating states and remain stable in different operating states, thereby improving safety and reliability. Furthermore, through the above arrangement, the rotating member 210 and the fixed member 220 can be locked by the first locking member 310 and the second locking member 320 located in different structures. This increases the service life of the locking device 300 and reduces the assembly requirements between the locking device 300 and the drive device 200, meeting the user's requirements for a simple connection structure with low assembly difficulty for the rotating structure of the rotor 100.

[0217] As an optional embodiment, refer to the attached Figure 2 , Attachment Figure 6 -Attached Figure 12 As shown, a movable connecting member 710 is further included, and the sleeve portion 622 and the second connecting member 700 are connected via the movable connecting member 710 so that the second connecting member 700 can rotate relative to the sleeve portion 622.

[0218] It should be noted that the specific structure of the movable connector 710 can be arbitrary. For example, the movable connector 710 can be a bearing, such as a ball bearing or a needle bearing; or a bushing, such as a copper bushing. The embodiments of the present application do not limit the specific structure of the movable connector 710, nor are they limited to the above examples.

[0219] It is understood that the second connecting member 700 may have a groove for accommodating the movable connecting member 710, and the movable connecting member 710 may be placed in the groove to guide the rotation of the second connecting member 700. The movable connecting member 710 may be fixedly connected to the sleeve portion 622 to ensure the rotation stability of the second connecting member 700.

[0220] Through the above-mentioned arrangement, the second connecting member 700 can be rotated relative to the sleeve portion 622, that is, the second connecting member 700 can be rotated relative to the fixed member 220, which can ensure that the rotating member 210 and the rotor 100 can rotate, and improve the connection strength between the rotor 100 and the drive device 200, so as to ensure that the rotor 100 can maintain a working state, can remain stable in different working states, and improve safety and reliability.

[0221] As an optional embodiment, refer to the attached Figure 6 -Attached Figure 12 As shown, along the extension direction perpendicular to the second sleeve 620 , the cross-sectional dimension of the docking portion 621 is larger than the cross-sectional dimension of the sleeve portion 622 , that is, along the direction of the rotation axis A of the rotating member 210 , the projection of the docking portion 621 can cover the projection of the sleeve portion 622 .

[0222] Furthermore, the second sleeve 620 also includes a first connecting portion 623 connected between the docking portion 621 and the sleeve portion 622. Along the extension direction of the second sleeve 620, the first connecting portion 623 has a large diameter end and a small diameter end. The large diameter end is connected to the docking portion 621, and the small diameter end is connected to the sleeve portion 622. At this time, the two ends of the first connecting portion 623 are respectively connected to the docking portion 621 and the sleeve portion 622, thereby ensuring the connection between the first sleeve 610 and the second sleeve 620.

[0223] It should be noted that to ensure that the first sleeve 610 can be well fitted around the outer circumference of the fixing member 220, the first sleeve 610 has a larger diameter. Accordingly, the docking portion 621 connected to the first sleeve 610 has a larger size. To reduce costs, the movable connector 710 can be smaller, meaning the sleeve portion 622 has a smaller size. In this case, to ensure that the larger docking portion 621 can connect with the smaller sleeve portion 622, the first connecting portion 623 can have a larger diameter and a smaller diameter, respectively.

[0224] It is understood that the first connecting portion 623 can be connected to the sleeve portion 622 and the docking portion 621 in any manner. For example, they can be bonded, threaded, or clamped together using screws, bolts, or other structures. In another example, the first connecting portion 623, the sleeve portion 622, and the docking portion 621 can be a single piece, and the second sleeve 620 can be an integrally formed structure. The embodiment of the present application does not limit the connection method between the first connecting portion 623, the sleeve portion 622, and the docking portion 621, nor is it limited to the above example.

[0225] The following description takes the first connecting portion 623, the sleeve portion 622 and the docking portion 621 as an integral part as an example. At this time, the second sleeve 620 has a higher structural stability and a higher structural strength, so as to enhance the connection stability between the first sleeve 610 and the second connecting member 700, to ensure that the rotor 100 can maintain a working state, can remain stable in different working states, and improve safety and reliability.

[0226] As an optional embodiment, refer to the attached Figure 2 , Attachment Figure 6 -Attached Figure 12 As shown, at least two lead wire holes 6231 are provided on the first connection portion 623 , and the at least two lead wire holes 6231 are spaced apart along the circumference of the first connection portion 623 .

[0227] It should be noted that the shape of the lead hole 6231 can be arbitrary. For example, the lead hole 6231 can be circular, elliptical, or square. The present embodiment of the application does not limit the specific shape of the lead hole 6231, nor is it limited to the above examples. The following description uses the example of an elliptical lead hole 6231.

[0228] Furthermore, the number of lead holes 6231 can be arbitrary. For example, the number of lead holes 6231 can be two, three, four, five, six, etc. The embodiment of the present application does not limit the specific number of lead holes 6231, nor is it limited to the above examples.

[0229] Through the above-mentioned arrangement, the second sleeve 620 can guide the wire through the wire hole 6231 to avoid bending of the wire, thereby ensuring the rotation of the rotor 100 and the normal use of the aircraft 10; in addition, the first sleeve 610 can achieve weight reduction through the wire hole 6231 to reduce the weight proportion of the second sleeve 620 in the rotor rotating device 20, which is beneficial to improving the lightweight of the rotor rotating device 20 and the aircraft 10.

[0230] As an optional embodiment, refer to the attached Figure 2 , Attachment Figure 6 -Attached Figure 12 As shown, the rotor rotating device 20 further includes a connecting shaft 900 , which passes through the second connecting member 700 and is connected to a side of the sleeve 600 facing away from the first connecting member 400 .

[0231] It is understood that the connection method between the connecting shaft 900 and the sleeve 600 can be arbitrary. For example, they can be bonded, threaded, or clamped. The embodiment of the present application does not limit the connection method between the connecting shaft 900 and the sleeve 600, nor is it limited to the above examples.

[0232] The following description will be made by taking the snap-fit ​​connection between the connecting shaft 900 and the sleeve 600 as an example.

[0233] Through the above arrangement, the connecting shaft 900 can be used to connect other structures of the aircraft 10 and can provide sufficient rotation space for the second connecting member 700 to avoid interference from other structures to ensure the rotation of the rotor 100.

[0234] As an optional embodiment, refer to the attached Figure 2 , Attachment Figure 6 -Attached Figure 12As shown, the connecting shaft 900 has a wire guide channel 910 , and a wire guide hole 920 communicating with the wire guide channel 910 is provided on the shaft wall of the connecting shaft 900 ; the wire guide hole 920 is located at one end of the connecting shaft 900 close to the sleeve 600 .

[0235] The wire channel 910 can be used to pass the wire through, thereby preventing the wire from bending; the wire hole 920 can also be used to pass the wire through, guide the wire, and also prevent the wire from bending. In other words, the wire channel 910 and the wire hole 920 can be used to guide and protect the wire, thereby preventing the wire from bending during rotation, thereby increasing the service life of the wire.

[0236] As an optional embodiment, refer to the attached Figure 2 , Attachment Figure 8 And attached Figure 12 As shown, the sleeve 600 has a snap-fitting hole 624, which is located on the side of the sleeve 600 away from the first connecting member 400; the connecting shaft 900 has a snap-fitting portion 930 corresponding to the snap-fitting hole 624 on the side close to the sleeve 600, and the snap-fitting portion 930 can be snap-fitted at the snap-fitting hole 624.

[0237] Specifically, when the sleeve 600 includes a first sleeve 610 and a second sleeve 620, and the second sleeve 620 includes a sleeve portion 622, the sleeve portion 622 may have a snap-fitting hole 624. Correspondingly, the connecting shaft 900 has a snap-fitting portion 930 on a side adjacent to the sleeve portion 622 that corresponds to the snap-fitting hole 624. The snap-fitting portion 930 may be snap-fitted to the snap-fitting hole 624 to securely connect the connecting shaft 900 to the sleeve portion 622.

[0238] In order to prevent relative movement between the connecting shaft 900 and the sleeve portion 622 , the number of the clamping portions 930 and the number of the clamping holes 624 can be at least two and distributed at intervals.

[0239] For example, the number of the engaging portions 930 and the number of the engaging holes 624 can both be four. The four engaging portions 930 can be spaced apart along the axis of the connecting shaft 900, and two of the engaging portions 930 and the other two engaging portions 930 can be arranged opposite each other along the circumferential direction of the connecting shaft 900. The specific number and distribution of the engaging holes 624 correspond to those of the engaging portions 930 and are not further described here.

[0240] Through the above arrangement, the connecting shaft 900 can be connected to the sleeve 600 through the clamping portion 930 and the clamping hole 624 to ensure that the connecting shaft 900 can be fixed to the fixing member 220 through the sleeve 600, which can increase the structural strength of the fixing member 220.

[0241] As an optional embodiment, the diameter of the portion of the connecting shaft 900 having the lead hole 920 is larger than the diameter of the portion of the connecting shaft 900 having the clamping portion 930. Figure 10 As shown, the diameter of the portion of the connecting shaft 900 having the wire hole 920 is B, and the diameter of the portion of the connecting shaft 900 having the clamping portion 930 is C, that is, B>C.

[0242] It is understood that the specific sizes of B and C are not limited in the present embodiment and can be adjusted according to actual conditions. Through the above arrangement, the connecting shaft 900 can form a stepped structure, which can be used to assist in the engagement of the positioning clamping portion 930 with the clamping hole 624, thereby assisting the connecting shaft 900 in engaging the sleeve 600.
