[0045] The following, in conjunction with the accompanying drawings and preferred embodiments of the present invention, further illustrates the technical means employed by the present invention to achieve its intended purpose.

[0046] The blade control assembly structure provided by this invention can be used in wind power generation, fans, and other equipment or devices that operate through blades, such as propellers. This invention does not specifically limit the application scope of the blade control assembly structure; the following examples are merely illustrative. Figures 1 to 24 The blade control assembly structure described in the embodiments of this application will be described in detail.

[0047] Please see Figures 1 to 3As shown in the figure, the basic blade control assembly structure provided in the first embodiment of the present invention is as follows. This basic blade control assembly structure includes a circular shaft 10, a signal device 20, a rotor body 30, and at least two blade assemblies 40. The circular shaft 10 has an outer diameter 101 and two ends 102 and 103. The signal device 20 controls the rotation of the blades according to rotation commands and includes multiple signal transmitters 201 capable of sending rotation commands, a decoder 50 for receiving rotation commands, and a drive motor 60 for controlling the rotation of the blades. The decoder and drive motor can be integrally formed or designed separately. The signal transmitters 201 are installed at appropriate peripheral positions 104 of the circular shaft 10, and their working surfaces are radially outward. The rotor body 30 has a shaft hole 301 and two ends 302 and 303, and a circumferential structure is provided around the rotor body 30. Multiple radial blade mounting structures 304 are hollow grooves 305. Decoders 50 and drive motors 60 can be installed in the grooves. The drive motors 60 are connected to the rotating column 405 of the connecting structure 404 at one end of the blade 401 via a shaft 601. The rotating column 405, in conjunction with the lubricating bearing Y1, can be smoothly adjusted in the hollow groove 305 to adjust the rotation angle, so that the blade 401 can be smoothly controlled to the required position by the signal device 20. The blade mounting structures 304, the rotating column 405, and the bearing Y1 can all be smoothly connected to each other using various active engagement methods or structures. The rotor body 30 rotates outside the circular shaft 10 through the shaft hole 301, causing the decoder 50 in the slot of the blade mounting structure 304 to continuously receive corresponding information from the signal transmitter 201 during rotation, so that the blade 401 receives the instruction to be rotated to a specific angle in a specific position. The energy required by the decoder 50 and the drive motor 60 is transmitted through the power ring PW on the circular shaft via contact or non-contact transmission. At least two blades, each blade 401 is plate-shaped and has two ends 402 and 403. One end 402 is provided with a connecting structure 404 and a rotating column 405. The blade assembly 40 is connected to an open end 306 of the blade mounting structure 304 through the rotating column 405, and is positioned by using the bearing Y1 to generate smoothness.

[0048] As shown in Figure 4, the blade control assembly structure provided in the second embodiment of the present invention is as follows. This embodiment is based on the first embodiment 1, except that a base 70 is added to the first embodiment. The base 70 is geometrically hollow 703 with two ends 701 and 702. One end 701 is connected to one end 103 of the round shaft 10. At a suitable position where it is connected to one end of the round shaft 10, at least one transmission gear T1 is provided in the groove 704 provided in the outer circle of the round shaft 10 and the base 70. The geometrically hollow 703 is used to accommodate the transmission mechanism and as a meshing transmission component. A transmission tooth 307 is added to the edge of one end 303 of the rotor body 30, and at least a first transmission gear T1 is also provided at the corresponding location on the base 70. The first transmission gear T1 passes through the side shaft hole 705 of the base 70 and the side shaft groove 104 of the round shaft 10 via a matching strip shaft S1, constraining the first transmission gear T1 between the round shaft 10 and the base 70, so that the first transmission gear T1 can be driven by the transmission tooth 307 of the rotor body 30. In addition to the first transmission gear T1, a second transmission gear, a third transmission gear, and a fourth transmission gear can also be used (please refer to...). Figure 5a As shown), multiple strip shafts S1 are used in conjunction, and the base 70 is also equipped with multiple grooves 704, which are then selected preferentially.

[0049] Figure 5a and 5bThe third embodiment of the present invention is shown. The blade control assembly structure provided in this embodiment is based on the above embodiment. An engine is provided in the hollow interior 703 of the base 70. This engine can be a single-shaft generator MD1. Furthermore, the drive shaft MD11 of the single-shaft generator MD1 is connected to a disc gear T2, which engages with the first drive gear T1 and is driven by the rotor body 30. A reducer PT may or may not be added between the single-shaft generator MD1 and the disc gear T2. The reducer PT is used to increase the torque of the single-shaft generator MD1. In addition, to position the rotor body 30 on the outer diameter 101 of the circular shaft 10, a positioning structure ST is specially added. This positioning structure ST can limit the rotor body 30 to rotate on the circular shaft using various conventional structures or other positioning components. Furthermore, to ensure smooth rotation of the rotor body 30, a lubricating bearing Y1 can be provided between the moving and stationary structures. The rotor body 30, equipped with a decoder 50 and a drive motor 60, is mounted on the periphery 101 of the circular shaft 10. When the entire blade control assembly is working, the user-set rotation command or the corresponding rotation command automatically generated by detecting external environmental information is sent to the signal device 20. The signal transmitter 201 on the signal device 20 then supplies the rotation command to the decoder 50 on the rotor body 30, instructing the blades 401 of the blade assembly 40 to be in a specific orientation with the maximum, minimum, or most appropriate area facing the wind or against the wind, ensuring that each blade assembly 40 achieves optimal wind pressure. This allows the gear structure 307, connected to the edge of one end 303 of the rotor body 30, to drive the gear T1 and the disc gear T2 to rotate the generator. For specific applications, see [link to relevant documentation]. Figure 6 The base 70 is used to horizontally position the blade assembly 40 of the present invention at position P via the fixed bracket K1, so that the blade assembly 40 can receive wind pressure.

[0050] For the blade operating mode of the blade control assembly structure in this embodiment of the invention, please refer to [link / reference]. Figure 7 and Figure 8Here, we will use a three-blade assembly 40 as an example for illustration. When wind W1 blows from right to left in the diagram, blade 401 at position a can be controlled to receive wind pressure with the optimal area. When blade 401 turns to position b, it is also instructed to receive wind pressure with the maximum area. Blade 401 receives wind pressure at the maximum or optimal angle from position a to position f. Furthermore, when blade 401 turns to the windward side, it is instructed to turn to the position with the minimum area to face the wind pressure. Each blade of the three blade assemblies 40 is controlled to face the wind with the optimal area in the downwind direction, and vice versa in the upwind direction. It can be seen that because this invention receives wind pressure horizontally, it can receive wind pressure from all directions without repositioning, making it very suitable for generating optimal renewable energy for household units. Multiple sets of blade assemblies 40 can be used; here, we only use three sets as an example. The size of blade 401 can be changed as needed. Figure 8 The length and width of the leaves relative to Figure 7 They are all different.

[0051] like Figure 9 The diagram shows a coaxial compound blade control assembly structure according to a fourth embodiment of the present invention. This embodiment includes at least two or more basic blade control assembly structures from the first embodiment. Each basic blade control assembly structure's rotor body 30 shares a circular shaft L10. The circular shaft L10 is elongated and has two ends L102 and L103. The rotor bodies 30 of the at least two basic blade control assembly structures are arranged in two layers on the circular shaft L10. Specifically, a transmission gear T3 is installed between two rotor bodies 30, and transmission teeth T4 are provided on the contact surfaces of the corresponding rotor bodies 30. Thus, the rotor bodies 30 can drive each other through the transmission gear T3, thereby driving the engine MD1 in the engine block.

[0052] like Figure 10 The image shows a disc-shaped compound blade control assembly structure according to a fifth embodiment of the present invention. In this embodiment, it includes at least two or more of the basic blade control assembly structures from the first embodiment. Based on... Figure 9In this embodiment, a carrier S20 is added to support the signal transmitting device 20. This carrier is disc-shaped S201 and mounted at a suitable location on the outer edge 101 of the circular shaft 10. A connecting post S202 fixes the carrier S20 to the outer edge 101 of the circular shaft 10. Multiple signal transmitters S203 can be mounted on one or both sides of the carrier S20, located at the circumferential edge of the carrier. The corresponding decoder 50 is located on the side of the blade mounting structure 304 adjusted to the periphery of the rotor body 30, opposite to the signal transmitters S201, and located in the radial transmission direction of the signal transmitters S201. The advantage of this embodiment is that it facilitates the development of diverse applications of the invention, allows for different applications, and provides varying levels of maintenance convenience.

[0053] like Figure 11 As shown, the sixth embodiment of the present invention provides a series coaxial compound blade control assembly structure. In this embodiment, based on the fourth and / or fifth embodiments, multiple blade control assembly structures are included. The figure shows two sets of blade control assembly structures Q1 and Q2, connected in series by a connecting column Z. The number of blades 401 can be adjusted based on their surface size; for example, the blade control assembly structure on the left side of the figure has more blades 401, while the blade control assembly structure on the right side has fewer. The purpose of the series connection is to enable the entire blade control assembly structure to withstand strong winds for wind power generation. A wind direction sensor T can be added to the top of each of the two independent sets Q1 and Q2 to detect external environmental information and automatically generate corresponding rotation commands to the signal transmitting device 201 of the present invention, so that the blades 401 receive optimal wind pressure to generate stronger wind power.

[0054] In the above embodiments, the blade 401 control assembly structure is applied in a horizontal direction, for example, as Figures 6 to 8 As shown, the blade 401 control assembly is applied in the horizontal direction. When horizontal, the blade 401 can receive wind from all directions without a steering mechanism. Of course, the application of this invention is not limited to the horizontal direction; it can also be applied in the vertical direction. The vertical direction is mainly used for large-scale wind power generation because the airflow is stronger at higher altitudes, and using this embodiment can enable the invention to achieve greater wind power generation efficiency. Figure 12 and Figure 13 As shown, the seventh embodiment of the present invention features a blade control assembly structure with a steering mount. This blade 401 control assembly is applied in the vertical direction. However, the vertically positioned blade 401 cannot receive wind direction from all directions. Therefore, preferably, when the blade control assembly is applied vertically, a steering mechanism 80 is installed at the mount 70 position. The steering mechanism 80 adjusts the direction of the blade control assembly structure, allowing the blade 401 to face the wind with maximum area. For details on the process of adjusting the blade according to the wind direction, please refer to [link to relevant documentation]. Figure 7 and Figure 8 The details of that will not be repeated here.

[0055] Furthermore, such as Figure 14 and Figure 15 As shown, this is the structure of the bidirectional frame-type blade control assembly according to the eighth embodiment of the present invention. This embodiment is based on... Figure 12 and Figure 13 The blade control assembly structure with a steering base has blade assemblies 40 on both sides of the base. That is, the blade assemblies 40 on both sides share a base 70. A drive motor is installed within the base 70. This drive motor consists of a dual-shaft drive motor MD2, and each shaft of the dual-shaft drive motor MD2 has a basic blade control assembly structure P1 and P2. A reducer PT can be added or omitted between the dual-shaft generator MD2 and the disc gear T2. This reducer PT increases the torque of the dual-shaft drive motor MD2. By sharing the base 70, the blades 401 on both sides can rotate synchronously. Compared to a blade control assembly structure with a single-sided blade assembly 40, the blade control assembly structure with dual-sided blade assemblies 40 can generate more electricity from wind power. Figure 18 The diagram shows a schematic of the rotation of the bidirectional frame-type blade control assembly structure with respect to direction. The direction of the blade 401 control assembly structure is adjusted by the steering mechanism 80 so that the blade 401 can face the wind with maximum area.

[0056] Furthermore, Figure 16This is a side sectional view of the blade control assembly structure according to the ninth embodiment of the present invention. In this embodiment, the blade control assembly structure extends the original rotor body 30 into an extended rotor body X30. The extended rotor body X30 has two ends X302 and X303, one of which X303 extends into one end 702 of the frame 70. One end X303 of the extended rotor body X30 includes an extension X304, which is connected to the drive shaft to drive the drive shaft to rotate. This mainly provides a meshing connection for the generator MD2 shaft MD21. The outer periphery of the body portion of one end X303 of the extended rotor body X30 is formed into a circular shaft X305. This circular shaft X305 serves as a connection point between the generator MD2 shaft MD21 and the frame 70. The rotating groove 702A is provided to allow the extended rotor body X30 to rotate within one end 702 of the base 70. A lubricated bearing Y1 is also provided between the cylindrical shaft X305 and the rotating groove 702A, so that the extended rotor body X30 can drive the shaft MD21 connected to the extension X304 to drive the generator MD2. In addition, a signal device X20 is provided on the inner edge of the rotating groove 702A within one end 702 of the base 70. The signal device X20 is provided with multiple signal transmitters X201. Multiple decoders X50 are provided on the periphery of the extension X304 of one end X303 of the extended rotor body X30, and they correspond to the signal transmitters X201. Thus, the blades 401 of the blade assembly 40 mounted on the extended rotor body X30 can be driven in the same way as in the above embodiments. The configuration of the signal transmitter X201 and decoder X50 in this embodiment is different from that in the above embodiments, so that the extended rotor body X30 does not need to drive the generator directly through gear transmission, thereby avoiding mechanical energy loss and increasing power generation efficiency.

[0057] Furthermore, Figure 17a and Figure 17b This is the tenth embodiment of the present invention, which is essentially the same as the ninth embodiment in terms of reducing mechanical energy loss. In this embodiment, one end 302 of the rotor body 30 is provided with a blade mounting structure 304, and the other end 303 rotates within one end 702 of the base 70 via a lubricated bearing Y1 and is fixed to the rotating shaft MD21 that drives the generator MD2. The only difference is that the signal transmitter X201 is now mounted on the edge of one end 702 of the base 70, while the decoder X50 is mounted at a corresponding appropriate position on the rotor body 30, transmitting the signal to the drive motor 60 within the blade mounting structure 304, thereby rotating the blades 401 of the blade assembly 40.

[0058] This invention further improves the structure of the blade 401 in the blade assembly, which helps to strengthen the structure of the blade 401. Specifically, as follows... Figures 19a-19cThe diagram shows the front view, side view, and sectional view of blade 401. The side view reveals that the blade 401 gradually thins from the petiole towards the blade tip, forming a wedge shape. The front and sectional views show that the blade surface of 401 employs a guide groove structure 30, which enhances wind resistance stability.

[0059] Figure 20 and Figure 21 The diagram shown is a schematic of the rotary blade control assembly structure provided in the eleventh embodiment of the present invention. This embodiment's blade control assembly structure is based on the embodiment shown in Figure 4. Unlike the embodiment shown in Figure 4, the rotor body 30 in this embodiment has been further improved. This embodiment includes two rotor bodies: a first rotor body 30A is drive-connected to the base 70, and a second rotor body 30B is located away from the base 70 and shares a circular shaft 10 with the first rotor body 30A. A wind direction detection device OP is provided at the end of the second rotor body 30B. The blade mounting structure 304 of each rotor body is bent, and the bent ends of the blade mounting structures 304 of the two rotor bodies are connected to a blade 401, thus forming a rotary structure with the blade 401 and the blade mounting structure 304. The configuration of the signal transmitter 201 and the decoder 50 is also modified in this embodiment. Specifically, the signal transmitter 201 is also located at the outer edge of the circular shaft 10, while the decoder 50 is located near the end of the blade mounting structure 304 on the circular shaft 10, and in the radial transmission direction of the signal transmitter 201. Since the blades in this embodiment are connected by two blade mounting structures 304, the drive motor 60 and decoder 50 can be installed in each of the two blade mounting structures 304, with the blades controlled by both sets of drive motors 60 and decoders 50. Alternatively, the drive motor 60 and decoder 50 can be installed in only one blade mounting structure 304. The blade 401 can be controlled by one set of drive motors 60 and decoders 50. The number of blades can be set to at least two or more as needed, for example... Figure 21 In this configuration, there are two blades. When rotating to a downwind direction, blade 401 adjusts to a vertical position, maximizing the frontal area to drive the blade's rotation. When rotating against the wind, blade 401 adjusts to a horizontal position, minimizing the frontal area to avoid kinetic energy loss. Figure 23 As shown in the twelfth embodiment of the present invention, based on the above embodiments, the blade control assembly structure adopts a double-sided blade structure. The base 70 is provided with a steering mechanism 80, which can realize the steering of the entire blade control assembly structure.

[0060] In the above embodiments, the blade control assembly structure is applied in wind power generation. By continuously adjusting the angle of the blade 401, the drag generated by the blade 401 when facing the wind is reduced, thereby improving the efficiency of wind power generation. The following embodiments mainly introduce the application of this blade control assembly structure in marine propellers and fans.

[0061] Figure 24 and Figure 25 This is a schematic diagram of a fan blade control assembly structure according to the thirteenth embodiment of the present invention. It includes a circular shaft B10, a rotor body B30, fan or (propeller) blades B40, and a base B70; the circular shaft B10 has an outer diameter B101 and two ends B102, B103, and a hollow position B105; the rotor body B30 has a shaft hole B301 and two ends B302, B303, and multiple radial fan blades B40 are arranged around the rotor body B30. The rotor body B30 can rotate outside the circular shaft B101 through the shaft hole B301; the fan blades B40 have two or more blades B401. In this embodiment, three blades are used. Blades B401 are disposed around the rotor body B30 by B304; a base B70 is geometrically hollow B703 with two ends B701 and B702, one end B701 is connected to one end B103 of a round shaft B10, and at a suitable position where it is connected to one end of the round shaft B10, at least one transmission gear T1 is provided in the groove B704 provided for it on the outer circle of the round shaft B10 and the base B70, and the geometrically hollow B703 is used for accommodation, such as accommodating the transmission mechanism and serving as a meshing transmission component. A transmission tooth B307 is added to the edge of one end B303 of the rotor body B30, and at least a first transmission gear T1 is also provided at the corresponding position of the base B70. The first transmission gear T1 passes through the side shaft hole B705 of the base 70 and the side shaft groove B104 of the round shaft B10 through a matching strip shaft S1, constraining the first transmission gear T1 between the round shaft B10 and the base B70, so that the first transmission gear T1 can be driven by the transmission tooth B307 of the rotor body B30. In addition to the first transmission gear T1, a second transmission gear, a third transmission gear, a fourth transmission gear (see Figure 5), and multiple strip shafts S1 can also be used, and the base B70 is also equipped with multiple grooves B704 for selection.

[0062] As described above, the blade control assembly structure provided in this embodiment is used in a fan. Unlike traditional fans that use a shaft and fan blades, the fan in this embodiment allows the rotor body B30 to rotate on a fixed circular shaft B10. Since the hollow position B105 of the circular shaft B10 at the center of the fan is completely hollow, the extended space of this hollow position B105 can be used to connect various devices, providing expandable functionality for the fan. For example, switches or other control devices can be installed in the hollow position B105, eliminating the need for a separate control panel and making the entire fan device simpler and more streamlined. Alternatively, lights or humidifiers can be installed in the hollow position B105, expanding the fan's functionality and making it more convenient for users in their daily lives.
