Technical Field

[0001] The invention relates to the technical field of energy-saving motors, and in particular to a limited-angle energy-saving motor with an automatic speed regulating mechanism. Background Art

[0002] The principle of limited angle motor is based on the limitation of rotation angle, which is consistent with the structure of conventional motor. Its advantage lies in precise rotation control, the ability to stop within the set angle, and higher accuracy than traditional motors. It is specifically used in high-precision equipment such as robots, automation equipment, printers, medical devices, etc.

[0003] Conventional control methods are based on electromagnetic phenomena, but any moving object is affected by inertia. Especially for limited-angle motors, ignoring friction, the motion state of the drive shaft (rotation direction / angle / speed) is directly related to the electromagnetic field strength. However, the working accuracy of limited-angle motor applications is relatively high, and it is difficult to adapt the working accuracy requirements through electromagnetic field strength, resulting in differences in actual working parameters. In addition, for high-load applications, simple electromagnetic transmission methods are difficult to provide stable transmission stability.

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

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

[0006] The object of the present invention can be achieved by the following technical solutions: A limited-angle energy-saving motor with an automatic speed regulating mechanism comprises an outer shell, an electromagnetic drive assembly and a transmission rod, wherein a multi-element rotor assembly is arranged in a position inside the outer shell corresponding to the transmission rod, and the multi-element rotor assembly comprises a first drive rotor, a second drive rotor, a second lateral rotor and a first lateral rotor;

[0007] The first driving rotor and the second driving rotor are mounted on a transmission rod, gear components are mounted on both the second lateral rotor and the first lateral rotor, and the second lateral rotor and the first lateral rotor are rotationally connected to the outer shell through the gear component, and reversing ropes are connected between the second lateral rotor and the first driving rotor, and between the first lateral rotor and the second driving rotor.

[0008] It is further configured as follows: the second lateral rotor and the first lateral rotor are located on both sides of the transmission rod, an intermediate rotating wheel is installed between the second lateral rotor and the first lateral rotor, and a stabilizing rope is connected between the intermediate gear and the two gear members.

[0009] It is further configured that: the cross sections of the first drive rotor, the second drive 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 drive rotor, the second drive rotor, the second lateral rotor and the first lateral rotor are in the shape of an arc.

[0010] It is further configured that: the cross-sectional areas of the first driving rotor and the second driving rotor, the second lateral rotor and the first lateral rotor are equal, and the cross-sectional area of ​​the first driving rotor is larger than the cross-sectional area of ​​the first lateral rotor.

[0011] It is further configured that: the first driving rotor and the second driving rotor, and the second lateral rotor and the first lateral rotor are arranged at different angles.

[0012] It is further configured as follows: meshing straight gear plates and cooperating gear plates are respectively arranged on both sides of the gear member, the straight gear plates and cooperating gear plates are both arranged in the vertical direction, and the cooperating gear plates are slidably connected in the outer shell, and an inclined wedge block is installed at the lower end of the straight gear plate.

[0013] It is further configured as follows: a reversing slider and an electric push rod are provided at a lower side of the outer shell corresponding to the multi-element rotor assembly, and the reversing slider is slidably connected in the outer shell along the width direction of the outer shell through the electric push rod.

[0014] It is further configured that: a reverse bevel angle is provided at a position on the side where the inclined wedge block and the reversing sliding block are close to each other.

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

[0016] 1. The overall structure is based on the operation process of limited rotation angle. On the basis of not interfering with the normal electromagnetic transmission, a multi-rotor assembly is added, which specifically includes 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 are optimized and improved. Specifically, the four rotor structures are all in the shape of a regular triangular arc, and the transmission process is further optimized by matching the difference in cross-sectional area. In the normal rotation process of the transmission rod, the transmission process of the four rotors initially plays the purpose of autonomously changing the rotation speed of the transmission rod;

[0017] 2. Based on the above content, the overall structure includes multiple motion conversion processes, the essence of which is to convert the rotational motion of the gear member into the linear movement of the straight gear plate in the vertical direction, and then convert the linear movement of the straight gear plate in the vertical direction into the linear movement of the reversing slide in the horizontal direction. Based on this, a reverse motion conversion process is proposed, and a secondary linear movement conversion process is added to cooperate with the linear movement process of the straight gear plate. Specifically, the electric push rod actively interferes with the rotation speed of the first lateral rotor and the second lateral rotor to achieve the purpose of automatic speed / steering control, so as to better meet the working accuracy requirements in the application object.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1: 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, due to the influence of inertial force, the actual working parameters are different, and it is difficult to provide stable transmission stability. The following technical solutions are proposed:

[0028] Reference Figures 1 to 6 In this embodiment, a limited-angle energy-saving motor with an automatic speed regulating mechanism includes an outer shell 1, an electromagnetic drive assembly 3 and a transmission rod 2. The transmission rod 2 is provided with a multi-rotor assembly at a position corresponding to the inner portion of the outer shell 1. The multi-rotor assembly 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 driving rotor 4 and the second driving rotor 13 are mounted on the transmission rod 2, the second lateral rotor 9 and the first lateral rotor 5 are both mounted with gear parts 14, and the second lateral rotor 9 and the first lateral rotor 5 are rotationally connected to the outer shell 1 through the gear part 14, a reversing rope 7 is connected between the second lateral rotor 9 and the first driving rotor 4, and between the first lateral rotor 5 and the second driving rotor 13, the second lateral rotor 9 and the first lateral rotor 5 are located on both sides of the transmission rod 2, and an intermediate rotating wheel 15 is mounted between the second lateral rotor 9 and the first lateral rotor 5, and a stabilizing rope 16 is connected between the intermediate gear 15 and the two gear parts 14.

[0030] Basic principle: A brief description of the operation process of the motor structure is given, based on the electromagnetic drive assembly 3, which includes a rotor and a stator. When a quantitative current is input to the rotor, the stator generates an electromagnetic field. 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 described in detail;

[0031] However, it should be noted that the rotation angle of the limited angle motor is in the range of 0 to 360°, or even in the range of 0 to 10°, but the rotation angle of the transmission rod 2 cannot be accurately controlled by controlling the current alone, and the rotation state of the transmission rod 2 is in a relatively resistance-free state. For this purpose, a multi-element rotor assembly is added in the present invention, and specific reference is made to Figure 3 The key to the multi-rotor assembly is to set the second lateral rotor 9 and the first lateral rotor 5 based on the first driving rotor 4 and the second driving rotor 13, wherein the first driving rotor 4 and the second driving rotor 13 maintain a fixed connection with the transmission rod 2, so that they can rotate synchronously with the transmission rod 2, but the first driving rotor 4 and the second driving rotor 13 will be affected by the movement interference process of the second lateral rotor 9 and the first lateral rotor 5, and specifically need to cooperate with the structural shape of the second lateral rotor 9, the first lateral rotor 5, the first driving rotor 4, and the second driving rotor 13.

[0032] Embodiment 2: Description of the structure and appearance of the multi-element rotor assembly:

[0033] The cross sections of the first drive rotor 4, the second drive rotor 13, the second lateral rotor 9 and the first lateral rotor 5 are all in the shape of an equilateral triangle, and the outer edges of the first drive rotor 4, the second drive rotor 13, the second lateral rotor 9 and the first lateral rotor 5 are in the shape of an arc, the cross-sectional areas of the first drive rotor 4 and the second drive rotor 13, the second lateral rotor 9 and the first lateral rotor 5 are equal, and the cross-sectional area of ​​the first drive rotor 4 is larger than the cross-sectional area of ​​the first lateral rotor 5, and the first drive rotor 4 and the second drive rotor 13, the second lateral rotor 9 and the first lateral rotor 5 are arranged at different angles.

[0034] Program Description: 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 in a triangular arc shape, and 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. When the first drive rotor 4 and the second drive rotor 13 rotate, the second lateral rotor 9 and the first lateral rotor 5 are further driven to rotate by the reversing rope 7. 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 conventional circles, so that when an angular position of the second drive rotor 13 moves to a corresponding position, it will directly affect the relative length of the reversing rope 7 in a local position. For example: Figure 4The rotation process of the second drive rotor 13 and the second lateral rotor 9 in the figure is described. In the initial state, an angular position of the second lateral rotor 9 "supports" the upper position of the reversing rope 7, and cooperates with the arc-shaped outer edge of the upper side of the second drive rotor 13, resulting in the upper part of the reversing rope 7 being relatively horizontal, while the reversing rope 7 at the lower position is relatively inclined. Then, when the second drive rotor 13 rotates counterclockwise, the upper part of the reversing rope 7 switches from a relatively horizontal state to a relatively inclined state, so that the relative length of this part increases, so that the reversing rope 7 is relatively inclined. Figure 4 Based on the positional relationship in, when the second drive rotor 13 rotates counterclockwise by 0 to 60 degrees, the rotation speed of the second drive rotor 13 is reduced due to the motion interference of the second lateral rotor 9. This part specifically utilizes the structural appearance 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 movement stability of the transmission rod 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, mainly to maintain the working stability of the above-mentioned key structures.

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

[0037] Meshing straight gear plates 6 and cooperating gear plates 8 are respectively arranged on both sides of the gear member 14. The 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. An inclined 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 at the lower side of the outer shell 1 corresponding to the multi-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, and a reverse bevel is arranged on the side where the inclined wedge block 10 and the reversing slider 11 are close to each other.

[0038] Solution Description: Refer again Figure 5 or Figure 4To illustrate, the gear member 14 is connected with the second lateral rotor 9 and the first lateral rotor 5 and keeps synchronous rotation. When the second lateral rotor 9 and the first lateral rotor 5 rotate by a certain angle, the gear member 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 provided in cooperation with the gear member 14 are kept in meshing state with the gear member 14, and the straight gear half 6 and the cooperating gear plate 8 are respectively provided at the two sides of the gear member 14, so that during the rotation of the gear member 14, the straight gear half 6 and the cooperating gear plate 8 will both move linearly, and the linear movement directions of the straight gear plate 6 and the cooperating gear plate 8 are opposite.

[0039] Specifically, it is necessary to limit the setting position of the straight gear plate 6 according to the rotation direction / setting position of the second lateral rotor 9, the first lateral rotor 5, and the transmission rod 2, so as to Figure 5 For example, because the key content of the present invention needs to ensure that the two straight gear plates 6 move downward, assuming that the second lateral rotor 9 and the first lateral rotor 5 rotate counterclockwise, it is necessary to ensure that the two straight gear plates 6 are located on the left side of the gear member 14 to ensure that the two straight gear plates 6 move downward, and 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 to ensure that the cooperating gear plates 8 slide in the vertical direction;

[0040] The linear movement process of the straight gear plate 6 is explained again: it is necessary to add a reversing slide block 11 at its lower side, which essentially converts the rotation of the gear member 14 into the linear movement of the straight gear plate 6 in the vertical direction, and then converts the linear movement of the straight gear plate 6 in the vertical direction into the linear movement of the reversing slide 11 in the horizontal direction, specifically, the reversing slide 11 is driven to move in the direction close to the transmission rod 2 through the reverse bevel angle between the inclined wedge block 10 and the reversing slide 11;

[0041] It should be summarized that the linear movement of the reversing slide 11 can be further limited by the electric push rod 12, and the electric energy of the electric push rod 12 can also be used as the electric energy in the electromagnetic drive assembly 3, so that the linear movement of the straight gear plate 6 is first limited by the active limitation of the electric push rod 12, and then the rotation speed of the second lateral rotor 9 and the first lateral rotor 5 is limited, and finally it is used to limit the rotation speed of the transmission rod 2.

[0042] In summary: for the operation process of the limited angle motor, a multi-rotor assembly is added on the basis of not 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, and the structural shape, connection method and transmission process of the four rotor structures are restricted. When the transmission rod rotates normally, the adaptive rotation process can be driven in the whole multi-rotor assembly. On this basis, 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 rotation speed of the first lateral rotor and the second lateral rotor to achieve the purpose of automatic speed / steering control, so as to better meet the working accuracy requirements in the application object.
