Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor technology, and specifically relates to a gimbal motor and gimbal with a limiting structure. Background Technology
[0002] The motor of the gimbal is one of the core components of the gimbal system, mainly used to drive the rotation and pitch movements of the gimbal. Gimbal motors typically need to have high precision, high stability, and high response speed to ensure that the gimbal can smoothly and accurately track the target or maintain stability.
[0003] A gimbal motor generally includes a stator assembly and a rotor assembly, and the rotor assembly can rotate relative to the stator assembly. In actual use, in order to prevent the camera and other devices driven by the rotor assembly from rotating indefinitely, a limiting structure is often used to limit the rotation of the gimbal motor after the rotor assembly has rotated to a certain extent. In the existing technology, the limiting structure is usually set on the gimbal, which makes the overall structure of the gimbal relatively bulky, disproportionate and affecting the aesthetics. Utility Model Content
[0004] In view of the above problems, this application provides a gimbal motor and gimbal with a limiting structure, which can simplify the structure of the gimbal, reduce the bulkiness of the gimbal structure, and improve the aesthetics of the gimbal structure while limiting the rotation angle of the gimbal.
[0005] In a first aspect, embodiments of this application provide a gimbal motor with a limiting structure, comprising a stator assembly, a rotor assembly, a first limiting assembly, and a second limiting assembly. The rotor assembly is coaxially and rotatably disposed on the stator assembly; the first limiting assembly is disposed on the side of the stator assembly facing the rotor assembly and has a first end and a second end disposed opposite to each other; the second limiting assembly is disposed on the side of the rotor assembly facing the stator assembly and has a third end and a fourth end disposed opposite to each other; the rotor assembly has a first position and a second position disposed opposite to each other in its stroke; in the first position, the first end and the third end abut against each other to restrict the rotor assembly from rotating away from the second position; in the second position, the second end and the fourth end abut against each other to restrict the rotor assembly from rotating away from the first position.
[0006] Specifically, when the rotor assembly of the gimbal motor with the limiting structure rotates from the first position to the second position, the fourth end of the second limiting component abuts against the second end of the first limiting member to restrict the rotor assembly from continuing to rotate away from the first position in the second position, thereby restricting the gimbal motor with the limiting structure to the second position, so that the gimbal with the gimbal motor can be restricted to rotate at a specific angle; when the rotor assembly of the gimbal motor with the limiting structure rotates from the second position to the first position, the third end of the second limiting component abuts against the first end of the first limiting member to restrict the rotor assembly from continuing to rotate away from the second position in the first position, thereby restricting the gimbal motor with the limiting structure to the first position, so that the gimbal with the gimbal motor can be restricted to rotate at another specific angle.
[0007] In the above technical solution, the gimbal motor with a limiting structure can be restricted to a specific position by the first limiting component and the second limiting component. Since the first limiting component is located on the side of the stator assembly facing the rotor assembly, and the second limiting component is located on the side of the rotor assembly facing the stator assembly, that is, the first limiting component and the second limiting component are located between the direction of the stator assembly and the rotor assembly combination, there is no need to add additional structures to the outer periphery of the stator assembly and the rotor assembly, thereby reducing the size of the gimbal motor with the limiting structure. At the same time, since the gimbal motor with the limiting structure has a limiting structure, there is no need to set a limiting structure on the gimbal, thereby simplifying the structure of the gimbal, reducing the bulkiness of the gimbal structure, and improving the aesthetics of the gimbal structure.
[0008] In some embodiments, the first limiting component includes a first limiting member and a second limiting member disposed circumferentially between the stator component and the rotor component; the second limiting component includes a third limiting member and a fourth limiting member disposed circumferentially between the rotor component and the rotor component; in the first position, the first limiting member and the third limiting member abut against each other; in the second position, the second limiting member and the fourth limiting member abut against each other.
[0009] In the above technical solution, by setting the first limiting component as a separate first limiting member and second limiting member, the volume of the first limiting component is reduced compared to setting the first component as a whole extending circumferentially along the stator assembly. This reduces the risk of interference between the first limiting component and structural components in the stator assembly, and also reduces the amount of material used in the first limiting component, thus lowering the production cost of the gimbal motor with the limiting structure. Similarly, by setting the second limiting component as a separate third limiting member and fourth limiting member, the volume of the second limiting component is reduced compared to setting the second component as a whole extending circumferentially along the stator assembly. This reduces the risk of interference between the second limiting component and structural components in the rotor assembly, and also reduces the amount of material used in the second limiting component, thus lowering the production cost of the gimbal motor with the limiting structure.
[0010] In some embodiments, the first limiting component is detachably mounted on the stator assembly; the second limiting component is detachably mounted on the rotor assembly; the first limiting component, the second limiting component, the third limiting component, and the fourth limiting component are all positioning pins.
[0011] In the above technical solution, the first limiting component, the second limiting component, the third limiting component, and the fourth limiting component are all positioning pins, which makes the first limiting component, the second limiting component, the third limiting component, and the fourth limiting component universal, thereby facilitating the replacement of the first limiting component, the second limiting component, the third limiting component, and the fourth limiting component, and thus facilitating the maintenance of the gimbal motor.
[0012] In some embodiments, the stator assembly and the rotor assembly surround a receiving cavity, and both the first limiting assembly and the second limiting assembly are located within the receiving cavity.
[0013] In the above technical solution, the stator assembly and the rotor assembly form a receiving cavity, and the first limiting assembly and the second limiting assembly are placed in the receiving cavity to provide a stable working environment for the first limiting assembly and the second limiting assembly, thereby improving the reliability of the gimbal motor.
[0014] In some embodiments, the stator assembly includes a mounting base and a motor stator; the mounting base has mounting holes; the motor stator is sleeved outside the mounting base. The rotor assembly includes a rotating shaft, a housing, and a magnetic element; one end of the rotating shaft is rotatably disposed within the mounting hole; the housing is sleeved at the other end of the rotating shaft located outside the mounting hole; the magnetic element is disposed in the housing and sleeved outside the motor stator, and the motor stator is used to generate a rotating magnetic field to drive the magnetic element to rotate the housing and the rotating shaft.
[0015] In the above technical solution, a rotating magnetic field is generated by the motor stator to drive the magnetic element to rotate the housing and the rotating shaft, thereby driving the rotor assembly to rotate. The structure is simple and easy to implement.
[0016] In some embodiments, the gimbal motor with a limiting structure further includes a bearing assembly, wherein the inner ring of the bearing assembly is sleeved outside the rotating shaft, and the outer ring of the bearing assembly is adapted to the mounting hole.
[0017] In the above technical solution, the rotating shaft is rotatably mounted in the mounting hole by means of a bearing assembly, which is simple in structure and easy to implement.
[0018] In some embodiments, the mounting base includes a first body and a first protrusion; the first protrusion protrudes from one side of the first body, the mounting hole passes through the first body and the first protrusion, and the motor stator is sleeved on the outside of the first protrusion.
[0019] In the above technical solution, by setting a first protrusion to provide a mounting position for the motor stator and providing support force to the motor stator during the operation of the gimbal motor, the reliability of the gimbal motor during its movement is improved.
[0020] In some embodiments, the housing includes a second body and a second protrusion; the second body is sleeved on one end of the rotating shaft; the second protrusion protrudes from the side of the second body facing the first body and is arranged around the rotating shaft, and the magnetic element is disposed on the inner circumferential side of the second protrusion; the first body, the first protrusion, the second body and the second protrusion form the receiving cavity.
[0021] In the above technical solution, by setting a second protrusion to provide a mounting position for the magnetic element and increasing the connection area between the magnetic element and the housing, the magnetic element can drive the second body to rotate through the second protrusion during the operation of the gimbal motor, thereby driving the rotor assembly to rotate, thus improving the reliability of the gimbal motor during operation.
[0022] In some embodiments, a first gap exists between the first protrusion and the second body along the extension direction of the rotation axis of the rotor assembly; the first limiting component and the second limiting component are located within the first gap.
[0023] In the above technical solution, the first limiting component and the second limiting component are located within the first gap, so that the first limiting component and the second limiting component can be staggered with the magnetic element and the motor stator in the extension direction of the rotation axis of the rotor assembly, thereby reducing the risk of the first limiting component and the second limiting component interfering with the relative movement of the magnetic element and the motor stator.
[0024] In a second aspect, embodiments of this application provide a gimbal including a gimbal motor with a limiting structure as described in any embodiment of the first aspect.
[0025] In the above technical solution, the gimbal motor with the aforementioned limiting structure has the beneficial effects of the aforementioned gimbal motor with the aforementioned limiting structure. Since the gimbal motor with the limiting structure has a limiting structure, there is no need to set a limiting structure on the gimbal, thereby simplifying the structure of the gimbal, reducing the bulkiness of the gimbal structure, and improving the aesthetics of the gimbal structure.

[0037] The motor of a gimbal is one of the core components of a gimbal system, primarily used to drive the rotation and pitch movements of the gimbal. Gimbal motors typically need to possess high precision, high stability, and high response speed to ensure the gimbal can smoothly and accurately track targets or maintain stability. A gimbal motor generally consists of a stator assembly and a rotor assembly, with the rotor assembly capable of rotating relative to the stator assembly. In practical applications, to prevent the camera and other devices driven by the rotor assembly from rotating indefinitely, a limiting structure is often used to restrict the rotation of the gimbal motor after the rotor assembly has reached a certain point. Current technology often places the limiting structure on the gimbal itself, resulting in a bulky overall structure with disproportionate aesthetics.
[0038] To solve the above technical problems, refer to Figures 1-4 This application provides a gimbal motor 100 with a limiting structure, including a stator assembly 10, a rotor assembly 20, a first limiting assembly 30, and a second limiting assembly 40. The rotor assembly 20 is coaxially and rotatably disposed on the stator assembly 10; the first limiting assembly 30 is disposed on the side of the stator assembly 10 facing the rotor assembly 20, and has a first end 301 and a second end 302 disposed opposite to each other; the second limiting assembly 40 is disposed on the side of the rotor assembly 20 facing the stator assembly 10, and has a third end 401 and a fourth end 402 disposed opposite to each other; the rotor assembly 20 has a first position and a second position disposed opposite to each other in its stroke; in the first position, the first end 301 and the third end 401 abut against each other to limit the rotor assembly 20 from rotating away from the second position; in the second position, the second end 302 and the fourth end 402 abut against each other to limit the rotor assembly 20 from rotating away from the first position.
[0039] As the name suggests, the stator assembly 10 is the stationary component in the gimbal motor, and the rotor assembly 20 is the component in the gimbal motor that rotates around the stator assembly 10.
[0040] Specifically, please refer to Figure 4When the rotor assembly 20 of the gimbal motor 100 with the aforementioned limiting structure rotates from the first position to the second position, the fourth end 402 of the second limiting component 40 abuts against the second end 302 of the first limiting member 31 to restrict the rotor assembly 20 from continuing to rotate away from the first position in the second position. This restricts the gimbal motor 100 with the limiting structure to the second position, thereby allowing the gimbal with this motor to be restricted from rotating at a specific angle. Please refer to... Figure 3 When the rotor assembly 20 of the gimbal motor 100 with the limiting structure rotates from the second position to the first position, the third end 401 of the second limiting component 40 abuts against the first end 301 of the first limiting member 31 to restrict the rotor assembly 20 from continuing to rotate away from the second position in the first position, thereby restricting the gimbal motor 100 with the limiting structure to the first position, so that the gimbal with the gimbal motor can be restricted to rotate at another specific angle.
[0041] In this technical solution, the gimbal motor 100 with a limiting structure can be restricted to a specific position by the first limiting component 30 and the second limiting component 40. Since the first limiting component 30 is disposed on the side of the stator assembly 10 facing the rotor assembly 20, and the second limiting component 40 is disposed on the side of the rotor assembly 20 facing the stator assembly 10, that is, the first limiting component 30 and the second limiting component 40 are located between the directions in which the stator assembly 10 and the rotor assembly 20 are combined, there is no need to add additional structures to the outer periphery of the stator assembly 10 and the rotor assembly 20, thereby reducing the size of the gimbal motor 100 with the limiting structure. At the same time, since the gimbal motor 100 with the limiting structure has a limiting structure, there is no need to set a limiting structure on the gimbal, thereby simplifying the structure of the gimbal, reducing the bulkiness of the gimbal structure, and improving the aesthetics of the gimbal structure.
[0042] According to some embodiments of this application, please refer to Figures 3-6 The first limiting component 30 includes a first limiting member 31 and a second limiting member 32 spaced apart along the circumference of the stator assembly 10; the second limiting component 40 includes a third limiting member 41 and a fourth limiting member 42 spaced apart along the circumference of the rotor assembly 20; in the first position, the first limiting member 31 and the third limiting member 41 abut; in the second position, the second limiting member 32 and the fourth limiting member 42 abut.
[0043] In this technical solution, by setting the first limiting component 30 as a separate first limiting member 31 and second limiting member 32, the volume of the first limiting component 30 is reduced compared to setting the first component as a whole extending circumferentially along the stator assembly 10. This reduces the risk of interference between the first limiting component 30 and the structural components in the stator assembly 10, and also reduces the amount of material used in the first limiting component 30, thus lowering the production cost of the gimbal motor 100 with the limiting structure. Similarly, by setting the second limiting component 40 as a separate third limiting member 41 and fourth limiting member 42, the volume of the second limiting component 40 is reduced compared to setting the second component as a whole extending circumferentially along the stator assembly 10. This reduces the risk of interference between the second limiting component 40 and the structural components in the rotor assembly 20, and also reduces the amount of material used in the second limiting component 40, thus lowering the production cost of the gimbal motor 100 with the limiting structure.
[0044] According to some embodiments of this application, the first limiting component 30 is detachably installed on the stator assembly 10; the second limiting component 40 is detachably installed on the rotor assembly 20; the first limiting component 31, the second limiting component 32, the third limiting component 41 and the fourth limiting component 42 are all positioning pins.
[0045] Locating pins are a common type of mechanical part, mainly used to ensure precise alignment and fixation between parts during assembly.
[0046] In this technical solution, the first limiting member 31, the second limiting member 32, the third limiting member 41, and the fourth limiting member 42 are all positioning pins, which makes the first limiting member 31, the second limiting member 32, the third limiting member 41, and the fourth limiting member 42 universal, thereby facilitating the replacement of the first limiting member 31, the second limiting member 32, the third limiting member 41, and the fourth limiting member 42, and thus facilitating the maintenance of the gimbal motor.
[0047] According to some embodiments of this application, the stator assembly 10 and the rotor assembly 20 are arranged to form a receiving cavity 1001, and the first limiting assembly 30 and the second limiting assembly 40 are both located within the receiving cavity 1001.
[0048] For example, one of the stator assembly 10 and the rotor assembly 20 may be a shell-shaped part with an opening at one end, and the other may be a plate-shaped part serving as a cover, with the other part covering the opening to jointly form a receiving cavity 1001; or, both the stator assembly 10 and the rotor assembly 20 may be shell-shaped parts with an opening at one end, and the two may be interlocked to form a receiving cavity 1001.
[0049] In this technical solution, the stator assembly 10 and the rotor assembly 20 form a receiving cavity 1001, and the first electric limiting assembly 30 and the second limiting assembly 40 are disposed in the receiving cavity 1001 to provide a stable working environment for the first limiting assembly 30 and the second limiting assembly 40, thereby improving the reliability of the gimbal motor.
[0050] According to some embodiments of this application, the stator assembly 10 includes a mounting base 11 and a motor stator 12; the mounting base 11 is provided with a mounting hole 101; the motor stator 12 is sleeved on the mounting base 11. The rotor assembly 20 includes a rotating shaft 22, a housing 21, and a magnetic element 23; one end of the rotating shaft 22 is rotatably disposed within the mounting hole 101; the housing 21 is sleeved on the other end of the rotating shaft 22 located outside the mounting hole 101; the magnetic element 23 is disposed on the housing 21 and sleeved on the motor stator 12, and the motor stator 12 is used to generate a rotating magnetic field to drive the magnetic element 23 to rotate the housing 21 and the rotating shaft 22.
[0051] The stator 12 is an important component of the gimbal motor, and its main function is to generate a rotating magnetic field. The stator consists of three parts: the stator core, the stator windings, and the frame. The stator core is usually made of laminated silicon steel sheets to reduce eddy current losses, while the stator windings are wires wound in the slots of the core to generate the magnetic field.
[0052] The working principle of the motor stator is to generate a rotating magnetic field in the stator windings by using three-phase alternating current. Specifically, when three stator windings at 120° intervals are energized with three-phase alternating current, a time-varying magnetic field is generated. This magnetic field moves in a certain direction in the stator space, forming a rotating magnetic field. This rotating magnetic field interacts with the magnetic elements 23 in the rotor assembly 20 to generate electromagnetic torque, driving the rotor assembly 20 to rotate.
[0053] In this technical solution, the motor stator 12 generates a rotating magnetic field to drive the magnetic element 23 to rotate the housing 21 and the rotating shaft 22, thereby driving the rotor assembly 20 to rotate. The structure is simple and easy to implement.
[0054] According to some embodiments of this application, the gimbal motor 100 with a limiting structure further includes a bearing assembly 50, the inner ring of which is sleeved outside the rotating shaft 22, and the outer ring of which is adapted to the mounting hole 101.
[0055] The bearing assembly 50 is an assembly consisting of at least one bearing.
[0056] The outer ring of bearing assembly 50 refers to the entirety of the outer rings of all bearings in bearing assembly 50 and the components that abut against the outer rings; the inner ring of bearing assembly 50 refers to the entirety of the inner rings of all bearings in bearing assembly 50 and the components that abut against the inner rings.
[0057] In this technical solution, the rotating shaft 22 is rotatably mounted in the mounting hole 101 by the bearing assembly 50, which is simple in structure and easy to implement.
[0058] According to some embodiments of this application, the mounting base 11 includes a first body 111 and a first protrusion 112; the first protrusion 112 protrudes from one side of the first body 111, the mounting hole 101 passes through the first body 111 and the first protrusion 112, and the motor stator 12 is sleeved on the outside of the first protrusion 112.
[0059] For example, the first body 111 and the first protrusion 112 can be integrally formed by injection molding or other means, or the first body 111 and the first protrusion 112 can be separately provided and connected by screwing, welding or other means.
[0060] In this technical solution, by setting the first protrusion 112 to provide the installation position of the motor stator 12 and to provide support force to the motor stator 12 during the operation of the gimbal motor, the reliability of the gimbal motor during the movement process is improved.
[0061] According to some embodiments of this application, the housing 21 includes a second body 211 and a second protrusion 212; the second body 211 is sleeved on one end of the rotating shaft 22; the second protrusion 212 protrudes from the side of the second body 211 facing the first body 111 and is arranged around the rotating shaft 22; the magnetic element 23 is disposed on the inner circumferential side of the second protrusion 212; the first body 111, the first protrusion 112, the second body 211 and the second protrusion 212 form a receiving cavity 1001.
[0062] For example, the second body 211 and the second protrusion 212 can be integrally formed by injection molding or other means, or the second body 211 and the second protrusion 212 can be separately provided and connected by screwing, welding or other means.
[0063] In this technical solution, by providing a second protrusion 212 to provide a mounting position for the magnetic element 23 and increasing the connection area between the magnetic element 23 and the housing 21, the magnetic element 23 can drive the second body 211 to rotate through the second protrusion 212 during the operation of the gimbal motor, thereby driving the rotor assembly 20 to rotate, thus improving the reliability of the gimbal motor during operation.
[0064] According to some embodiments of this application, a first gap 102 exists between the first protrusion 112 and the second body 211 along the extension direction of the rotation axis 22 of the rotor assembly 20; the first limiting component 30 and the second limiting component 40 are located within the first gap 102.
[0065] "The first limiting component 30 and the second limiting component 40 are located within the first gap 102" can be understood as the orthographic projection of the first limiting component 30 and the second limiting component 40 on a plane perpendicular to the rotation axis 22 of the rotor assembly 20 being located within the orthographic projection of the first protrusion 112, and the first limiting component 30 and the second limiting component 40 being located between the first protrusion 112 and the second body 211.
[0066] In this technical solution, the first limiting component 30 and the second limiting component 40 are located within the first gap 102, thereby enabling the first limiting component 30 and the second limiting component 40 to be staggered with the magnetic element 23 and the motor stator 12 in the extension direction of the rotation axis 22 of the rotor assembly 20, thereby reducing the risk of the first limiting component 30 and the second limiting component 40 interfering with the relative movement of the magnetic element 23 and the motor stator 12.

[0068] In this technical solution, the gimbal motor 100 with the aforementioned limiting structure has the beneficial effects of the aforementioned gimbal motor 100 with the limiting structure. Since the gimbal motor 100 with the limiting structure has a limiting structure, there is no need to set a limiting structure on the gimbal, thereby simplifying the structure of the gimbal, reducing the bulkiness of the gimbal structure, and improving the aesthetics of the gimbal structure.
[0069] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.
