Description

Technical Field

[0001] This invention relates to the field of energy-saving motor technology, and specifically to a limited-angle energy-saving motor with an automatic speed regulation mechanism. Background Technology

[0002] The principle of a finite angle motor is based on limiting the rotation angle. Its structure is the same as that of a conventional motor. Its advantage lies in precise rotation control. It can stop within a set angle and has higher accuracy than traditional motors. It is specifically used in high-precision equipment such as robots, automation equipment, printers, and medical devices.

[0003] Conventional control methods are based on electromagnetic phenomena. However, any moving object is affected by inertial forces. Especially for finite-angle motors, ignoring friction, the motion state of the drive shaft (rotation direction / angle / speed) is directly related only to the electromagnetic field strength. However, finite-angle motors are used in applications requiring high precision, and it is difficult to adapt the electromagnetic field strength method to meet the precision requirements, resulting in differences in actual working parameters. Furthermore, for high-load applications, simple electromagnetic transmission methods cannot provide stable transmission stability.

[0004] This application proposes a solution to this problem. Summary of the Invention

[0005] The purpose of this invention is to provide a limited-angle energy-saving motor with an automatic speed regulation mechanism. For the application environment of limited-angle motors, a single electromagnetic field strength control method is difficult to fully adapt to the working accuracy requirements. Specifically, the existence of inertial force leads to differences in actual working parameters and makes it difficult to provide stable transmission stability.

[0006] The objective of this invention can be achieved through the following technical solution: a limited-angle energy-saving motor with an automatic speed regulation mechanism, comprising a housing, an electromagnetic drive assembly and a transmission shaft, wherein a multi-rotor assembly is provided in the housing corresponding to the position of the transmission shaft, and the multi-rotor assembly includes a first drive rotor, a second drive rotor, a second lateral rotor and a first lateral rotor.

[0007] The first drive rotor and the second drive rotor are mounted on the transmission shaft. Gear components are mounted on both the second lateral rotor and the first lateral rotor. The second lateral rotor and the first lateral rotor are rotatably connected to the outer casing through the gear components. A reversing rope connects the second lateral rotor to the first drive rotor and the first lateral rotor to the second drive rotor.

[0008] The configuration is further defined as follows: the second lateral rotor and the first lateral rotor are located on opposite sides of the drive shaft, and an intermediate wheel is installed between the second lateral rotor and the first lateral rotor, wherein a stabilizing rope is connected between the intermediate wheel and the two gear components.

[0009] The configuration is further defined as follows: the cross-sections of the first driving rotor, the second driving rotor, the second lateral rotor, and the first lateral rotor are all in the shape of an equilateral triangle, and the outer edges of the first driving rotor, the second driving rotor, the second lateral rotor, and the first lateral rotor are in the shape of an arc.

[0010] The configuration is further defined as follows: the cross-sectional areas of the first driving rotor and the second driving rotor, and the cross-sectional area of ​​the second lateral rotor and the first lateral rotor are equal, and the cross-sectional area of ​​the first driving rotor is greater than the cross-sectional area of ​​the first lateral rotor.

[0011] The setting angles of the first drive rotor and the second drive rotor, and the second lateral rotor and the first lateral rotor are different.

[0012] The gear component is further configured such that a meshing straight gear plate and a cooperating gear plate are respectively provided on both sides of the gear component, both the straight gear plate and the cooperating gear plate are arranged in the vertical direction, and the cooperating gear plate is slidably connected in the outer shell, and a wedge block is installed at the lower end of the straight gear plate.

[0013] The configuration is further defined as follows: a reversing slider and an electric push rod are provided on the lower side of the outer shell corresponding to the multi-rotor assembly, and the reversing slider is slidably connected in the outer shell along the width direction of the outer shell via the electric push rod.

[0014] A further configuration is provided: the wedge block and the reversing slider are positioned on the side that are close to each other with a reverse angle.

[0015] The present invention has the following beneficial effects:

[0016] 1. The overall structure is based on the operation process with a limited rotation angle. Without interfering with the normal electromagnetic transmission, a multi-rotor assembly is added, specifically including a first drive rotor, a second drive rotor, a second lateral rotor, and a first lateral rotor. The structural shape, connection method, and transmission process of the above four rotor structures have been optimized and improved. Specifically, all four rotor structures are equilateral triangular arc shapes, and the transmission process is further optimized by taking into account the difference in cross-sectional area. During the normal rotation of the transmission shaft, the transmission process of the four rotors initially achieves the purpose of autonomously changing the rotation speed of the transmission shaft.

[0017] 2. Based on the above, the overall structure includes multiple motion conversion processes. Essentially, it converts the rotational motion of the gear components into linear movement of the straight gear plate in the vertical direction, and then converts the linear movement of the straight gear plate in the vertical direction into linear movement of the reversing slider in the horizontal direction. Based on this, a reverse motion conversion process is proposed. To complement the linear movement of the straight gear plate, a secondary linear movement conversion process is added. Specifically, the electric push rod actively interferes with the rotational speed of the first lateral rotor and the second lateral rotor to achieve automatic speed / steering control, thereby better meeting the working accuracy requirements of the application.

Detailed Implementation

[0026] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: For applications involving finite-angle motors, a single electromagnetic field strength control method is insufficient to fully meet the required working accuracy. Specifically, the presence of inertial forces leads to discrepancies in actual operating parameters, and it is difficult to provide stable transmission stability. The following technical solution is proposed to address this issue:

[0028] Reference Figures 1-6 This embodiment of a limited-angle energy-saving motor with an automatic speed regulation mechanism includes a housing 1, an electromagnetic drive assembly 3 and a transmission shaft 2. The transmission shaft 2 is provided with a multi-rotor assembly in the housing 1, which includes a first drive rotor 4, a second drive rotor 13, a second lateral rotor 9 and a first lateral rotor 5.

[0029] The first drive rotor 4 and the second drive rotor 13 are mounted on the transmission shaft 2. Gear components 14 are mounted on both the second lateral rotor 9 and the first lateral rotor 5. The second lateral rotor 9 and the first lateral rotor 5 are rotatably connected to the outer casing 1 through the gear components 14. A reversing rope 7 is connected between the second lateral rotor 9 and the first drive rotor 4, and between the first lateral rotor 5 and the second drive rotor 13. The second lateral rotor 9 and the first lateral rotor 5 are located on both sides of the transmission shaft 2. An intermediate wheel 15 is installed between the second lateral rotor 9 and the first lateral rotor 5. A stabilizing rope 16 is connected between the intermediate wheel 15 and the two gear components 14.

[0030] Basic principle: The operation process of the motor structure is briefly explained, based on the electromagnetic drive assembly 3, which includes a rotor and a stator. When a fixed current is input to the rotor, an electromagnetic field is generated in conjunction with the stator. Under the action of the electromagnetic field, the rotor drives the transmission shaft 2 to rotate in a directional / constant speed. This part will not be explained in detail.

[0031] However, it should be noted that the rotation angle of the finite-angle motor is in the range of 0 to 360°, or even 0 to 10°. However, simply controlling the current will not precisely control the rotation angle of the drive shaft 2, and the rotation of the drive shaft 2 is in a relatively unresisted state. Therefore, this invention adds a multi-rotor assembly, as detailed in the following reference. Figure 3 The key to the multi-rotor assembly is that a second lateral rotor 9 and a first lateral rotor 5 are set up based on the first drive rotor 4 and the second drive rotor 13. The first drive rotor 4 and the second drive rotor 13 are fixedly connected to the transmission shaft 2, so that they can rotate synchronously with the transmission shaft 2. However, the first drive rotor 4 and the second drive rotor 13 will be subject to the motion interference process of the second lateral rotor 9 and the first lateral rotor 5. Specifically, it is necessary to match the structural shape of the second lateral rotor 9, the first lateral rotor 5, the first drive rotor 4, and the second drive rotor 13.

[0032] Example 2: Description of the structural shape of the multi-element rotor assembly:

[0033] The cross-sections of the first driving rotor 4, the second driving rotor 13, the second lateral rotor 9, and the first lateral rotor 5 are all equilateral triangular in shape, and the outer edges of the first driving rotor 4, the second driving rotor 13, the second lateral rotor 9, and the first lateral rotor 5 are arc-shaped. The cross-sectional areas of the first driving rotor 4, the second driving rotor 13, the second lateral rotor 9, and the first lateral rotor 5 are equal, and the cross-sectional area of ​​the first driving rotor 4 is larger than that of the first lateral rotor 5. The setting angles of the first driving rotor 4, the second driving rotor 13, the second lateral rotor 9, and the first lateral rotor 5 are different.

[0034] Solution Description: Based on Figure 4 and Figure 5 For example, the second lateral rotor 9, the first lateral rotor 5, the first drive rotor 4, and the second drive rotor 13 are triangular arc shapes, and a reversing rope 7 connects the second lateral rotor 9 to the first drive rotor 4, and the first lateral rotor 5 to the second drive rotor 13. When the first drive rotor 4 and the second drive rotor 13 rotate, the reversing rope 7 further drives the second lateral rotor 9 and the first lateral rotor 5 to rotate. However, it should be noted that the second lateral rotor 9, the first lateral rotor 5, the first drive rotor 4, and the second drive rotor 13 are not conventionally circular. Therefore, when one corner of the second drive rotor 13 moves to a corresponding position, it directly affects the relative length of the reversing rope 7 at a local position. For example: Figure 4The rotation process of the second drive rotor 13 and the second lateral rotor 9 will be explained. In the initial state, one corner of the second lateral rotor 9 "supports" the upper part of the reversing rope 7, and in conjunction with the arc-shaped outer edge of the upper side of the second drive rotor 13, the upper part of the reversing rope 7 is relatively horizontal, while the lower part of the reversing rope 7 is relatively inclined. When the second drive rotor 13 rotates counterclockwise, the upper part of the reversing rope 7 changes from a relatively horizontal state to a relatively inclined state, thereby increasing the relative length of this part. Figure 4 Based on the positional relationship, during the process of the second drive rotor 13 rotating counterclockwise from 0 to 60°, the rotational speed of the second drive rotor 13 is reduced due to the motion interference process of the second lateral rotor 9. This part specifically utilizes the structural shape of the second lateral rotor 9, the first lateral rotor 5, the first drive rotor 4, and the second drive rotor 13.

[0035] However, it should also be noted that in order to further maintain the motion stability of the drive shaft 2, the second lateral rotor 9, the first lateral rotor 5, the first drive rotor 4, and the second drive rotor 13, it is necessary to use a stabilizing rope 16 to combine the second lateral rotor 9, the first lateral rotor 5, the first drive rotor 4, and the second drive rotor 13 into one unit, mainly to maintain the working stability of the above-mentioned key structures.

[0036] Example 3: Based on Example 2, the operation process of the multi-rotor assembly is described:

[0037] On both sides of the gear component 14, there are meshing straight gear plates 6 and cooperating gear plates 8. Both straight gear plates 6 and cooperating gear plates 8 are arranged in the vertical direction, and the cooperating gear plate 8 is slidably connected in the outer shell 1. A wedge block 10 is installed at the lower end of the straight gear plate 6. A reversing slider 11 and an electric push rod 12 are arranged on the lower side of the outer shell 1 corresponding to the multi-element rotor assembly. The reversing slider 11 is slidably connected in the outer shell 1 along the width direction of the outer shell 1 through the electric push rod 12. A reverse angle is provided on the side of the wedge block 10 that is close to the reversing slider 11.

[0038] Solution Description: Please refer to the following again. Figure 5 or Figure 4To illustrate, the gear component 14 is connected to the second lateral rotor 9 and the first lateral rotor 5 and rotates synchronously. When the second lateral rotor 9 and the first lateral rotor 5 rotate a certain angle, the gear component 14 will also rotate by the same angle. However, the key point is that the straight gear half 6 and the cooperating gear plate 8 are provided in conjunction with the gear component 14. The straight gear half 6 and the cooperating gear plate 8 are in a meshing state with the gear component 14, and the straight gear half 6 and the cooperating gear plate 8 are respectively located on both sides of the gear component 14. Thus, during the rotation of the gear component 14, both the straight gear half 6 and the cooperating gear plate 8 will move linearly, and the linear movement directions of the straight gear plate 6 and the cooperating gear plate 8 are opposite.

[0039] Specifically, the placement of the straight gear plate 6 needs to be limited according to the rotation direction / position of the second lateral rotor 9, the first lateral rotor 5, and the drive shaft 2, so as to... Figure 5 For example, since the key content of this invention requires ensuring that the two straight gear plates 6 move downward, assuming that the second lateral rotor 9 and the first lateral rotor 5 both rotate counterclockwise, it is necessary to ensure that the two straight gear plates 6 are both located on the left side of the gear component 14 to ensure that the two straight gear plates 6 move downward. The other two cooperating gear plates 8 are mainly used to maintain the stability of the second lateral rotor 9 and the first lateral rotor 5 during rotation, specifically ensuring that the cooperating gear plates 8 slide in the vertical direction.

[0040] Regarding the linear movement process of the straight gear plate 6, it should be explained again that a reversing slider 11 needs to be added at its lower position. Its essence is to convert the rotation of the gear component 14 into the linear movement of the straight gear plate 6 in the vertical direction, and then convert the linear movement of the straight gear plate 6 in the vertical direction into the linear movement of the reversing slider 11 in the horizontal direction. Specifically, the reversing slider 11 is driven to move in the direction close to the transmission shaft 2 by the anti-oblique angle between the wedge block 10 and the reversing slider 11.

[0041] It should be summarized that the linear movement of the reversing slider 11 can be further restricted by the electric push rod 12, and the electrical energy of the electric push rod 12 can also be used as the electrical energy in the electromagnetic drive assembly 3. Thus, the linear movement of the straight gear plate 6 is first restricted by the electric push rod 12 in an active restriction manner, and then the rotational speed of the second lateral rotor 9 and the first lateral rotor 5 is restricted, and finally the rotational speed of the drive shaft 2 is restricted.

[0042] In summary: For the operation of a limited-angle motor, a multi-rotor assembly is added without interfering with the normal electromagnetic transmission. The multi-rotor assembly is specifically based on the first drive rotor, the second drive rotor, the second lateral rotor, and the first lateral rotor. It controls the structural shape, connection method, and transmission process of the four rotor structures. When the drive shaft rotates normally, it can drive the entire multi-rotor assembly to perform an adaptive rotation process. Based on this, a secondary linear movement conversion process is added in conjunction with the linear movement process of the straight gear plate. Specifically, the electric push rod actively interferes with the rotational speed of the first lateral rotor and the second lateral rotor to achieve automatic speed / direction control, thereby better meeting the working accuracy requirements of the application.
