Description

Technical Field

[0001] This utility model relates to the field of permanent magnet synchronous motor technology, and in particular to a clutch-type permanent magnet synchronous motor. Background Technology

[0002] The purpose of a clutch-type permanent magnet synchronous motor is to achieve flexible connection and disconnection between the motor and the load, allowing for on-demand driving according to actual working conditions and improving system operating efficiency. Its significance lies in effectively reducing energy consumption, minimizing unnecessary energy loss, and enhancing overall equipment performance. It is widely used in various industrial fields and new energy vehicles, contributing to the development of related industries towards energy conservation and high efficiency, and yielding significant economic and social benefits.

[0003] When a clutch-type permanent magnet synchronous motor is working, the engagement and disengagement of the clutch are controlled by electromagnetic force to connect or disconnect the motor from the load. When the clutch is engaged, the motor drives the load; when disengaged, the motor idles and the load stops. It is suitable for scenarios requiring frequent starts and stops and precise control, such as industrial automated production lines and elevators. It is also commonly used in new energy vehicles, where the motor can be disconnected during vehicle coasting or braking to reduce energy loss and improve energy efficiency.

[0004] In existing technologies, some clutch-type permanent magnet synchronous motors generally rely on springs or damping pads for vibration damping during use. However, springs may experience elastic fatigue after long-term use, leading to a decrease in vibration damping performance. Damping pads may also affect stability due to wear and aging. Therefore, a clutch-type permanent magnet synchronous motor is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a clutch-type permanent magnet synchronous motor, which aims to improve the problem in the prior art that springs may experience elastic fatigue after long-term use, leading to a decrease in shock absorption performance, and shock absorption pads may also affect stability due to wear and aging.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clutch-type permanent magnet synchronous motor includes a protective shell. A screw is threadedly connected to the inner wall of the protective shell. Two sliders are threadedly connected to the outer wall of the screw. A connecting rod is rotatably connected to the bottom of each of the two sliders. A connecting plate is rotatably connected to the other end of each of the two connecting rods. A fixing plate is fixedly connected to the bottom of each of the two connecting plates. A plurality of dampers are fixedly connected to the bottom of each fixing plate. A detachable component for disassembly is installed on the outer wall of the protective shell.

[0008] As a further description of the above technical solution:

[0009] The detachable component includes a mounting foot, the outer wall of which is fixedly connected to the bottom outer wall of the protective shell, a rotating plate is rotatably connected to the top of the mounting foot, and a base plate is detachably connected to the bottom of the protective shell.

[0010] As a further description of the above technical solution:

[0011] A rotating rod is rotatably connected to the top of the base plate, and a limiting plate is fixedly connected to the top of the rotating rod.

[0012] As a further description of the above technical solution:

[0013] The top of the protective shell is fixedly connected to a limit post, and the bottom inner wall of the rotating plate is detachably connected to the top outer wall of the slider.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the rotating plate is slidably connected to the outer wall of the rotating rod, and the top of the rotating plate is slidably connected to the bottom of the limiting plate.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the rotating plate is provided with a mounting groove, and the outer wall of the rotating rod is slidably connected to the inner wall of the mounting groove.

[0018] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] A synchronous motor is fixedly connected to the top of the base plate, and the bottom of the contact plate is in contact with the top of the synchronous motor.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, rotating the screw causes the slider to slide towards each other on the outer wall of the screw. Then, the sliding of the screw towards each other causes the connecting rod at the bottom of the screw to rotate. The rotation of the connecting rod causes the connecting rod to move downward. The rotation of the connecting rod causes the fixed plate to move downward. The downward movement of the fixed plate causes the damper and the bottom contact plate to move downward until they contact the synchronous motor. When the synchronous motor is running, it will generate vibration. At this time, the contact plate will transmit the vibration to the damper. The damper dissipates energy and suppresses vibration by converting the kinetic energy generated by the vibration or impact into other forms of energy.

[0024] 2. In this utility model, the rotating limiting plate and the mounting groove facilitate the control of the rotation of the limiting plate. At this time, the limiting plate changes from horizontal to vertical. Then, the rotating plate is rotated, which causes the rotating plate to be removed from the top of the limiting pile. The mounting groove on the inner wall of the rotating plate passes through the outside of the limiting plate once to complete the disassembly between the protective shell and the base plate. This makes it easy to remove the protective shell when the synchronous motor is damaged, so as to facilitate the maintenance of the synchronous motor. The function of the heat dissipation port is to dissipate heat from the synchronous motor. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of a clutch-type permanent magnet synchronous motor 11, including a protective shell 1. A screw 4 is threadedly connected to the inner wall of the protective shell 1. When the screw 4 rotates, it can drive the threadedly connected components to move, realizing related functions and providing a power basis for subsequent operations such as shock absorption. Two sliders 5 are threadedly connected to the outer wall of the screw 4. The two sliders 5 can slide towards each other on the outer wall of the screw 4 under the rotation of the screw 4. The sliding of the sliders 5 drives the movement of subsequent components, thereby realizing operations such as shock absorption of the synchronous motor 11. The bottom of each slider 5 is rotatably connected to a connecting rod 6. The sliding of the slider 5 will drive the connecting rod 6 to rotate. The rotation of the connecting rod 6 transmits and converts the motion of the slider 5 in order to realize subsequent operations.

[0033] The other ends of both connecting rods 6 are rotatably connected to connecting plates 7. The rotation of connecting rods 6 drives the connecting plates 7 to move. The connecting plates 7 play the role of connecting and transmitting motion, so that the motion can continue to be transmitted downward. The bottom of both connecting plates 7 is fixedly connected to fixing plates 8. The movement of connecting plates 7 will drive the movement of fixing plates 8. Fixing plates 8 are used to fix dampers 9 and other components. They are important connecting components for realizing the shock absorption function. Multiple dampers 9 are fixedly connected to the bottom of fixing plates 8. The dampers 9 can convert the kinetic energy generated by vibration or impact into other forms of energy, dissipate energy, suppress vibration, reduce the wear and fatigue of the motor caused by vibration, and extend the service life of motor bearings, windings and other components.

[0034] The outer wall of the protective shell 1 is equipped with a detachable component for easy removal. This component allows the protective shell 1 to be removed for repair of the synchronous motor 11 in case of damage. The inner wall of the protective shell 1 is detachably connected to the synchronous motor 11, which is the core component of the device. This detachable connection facilitates installation and maintenance. Contact plates 10 are fixedly connected to the bottom of the two dampers 9. These contact plates 10 contact the synchronous motor 11, transmitting the vibrations generated by the synchronous motor 11 during operation to the dampers 9, thereby controlling the vibrations of the synchronous motor 11. For vibration reduction, the outer wall of the protective shell 1 has multiple heat dissipation vents 3, which can dissipate heat from the synchronous motor 11, ensuring that the synchronous motor 11 operates in a suitable temperature environment and extending its service life. The top of the base plate 2 is fixedly connected to the synchronous motor 11, and the base plate 2 plays the role of supporting the synchronous motor 11 and ensuring the stable installation of the synchronous motor 11. The bottom of the contact plate 10 is in contact with the top of the synchronous motor 11. After the contact plate 10 contacts the synchronous motor 11, it can transmit the vibration of the synchronous motor 11 to the damper 9, thereby achieving vibration reduction of the synchronous motor 11.

[0035] Reference Figures 2 to 4The detachable component includes mounting feet 17, which are part of the detachable component and serve to connect the protective shell 1 and other components. The outer wall of the mounting feet 17 is fixedly connected to the bottom outer wall of the protective shell 1, making the connection between the mounting feet 17 and the protective shell 1 stable and providing a stable foundation for subsequent disassembly operations. A rotating plate 16 is rotatably connected to the top of the mounting feet 17. The rotating plate 16 can rotate on the top of the mounting feet 17, and the disassembly operations between the protective shell 1 and the base plate 2 can be achieved by rotating the rotating plate 16.

[0036] The bottom of the protective shell 1 is detachably connected to a base plate 2. This detachable connection allows the protective shell 1 and the base plate 2 to be separated when needed, facilitating maintenance of the synchronous motor 11. A rotating rod 14 is rotatably connected to the top of the base plate 2. The rotation of the rotating rod 14 can drive the limit plate 12 to rotate, thus providing the conditions for disassembling the protective shell 1 and the base plate 2. The limit plate 12 is fixedly connected to the top of the rotating rod 14. The limit plate 12 is used to limit the position of the rotating plate 16 and plays a fixing role during installation. During disassembly, the disassembly operation is achieved by rotating the limit plate 12. A limit stake 15 is fixedly connected to the top of the protective shell 1. The limit stake 15 is used to cooperate with the rotating plate 16 to limit the position of the rotating plate 16 and ensure the installation stability of the device. The bottom inner wall of the rotating plate 16 is detachably connected to the top outer wall of the slider 5. The detachable connection between the rotating plate 16 and the slider 5 allows the rotating plate 16 to participate in the operation of the entire device and can be disassembled when needed.

[0037] The inner wall of the rotating plate 16 is slidably connected to the outer wall of the rotating rod 14. The rotating plate 16 slides on the outer wall of the rotating rod 14, allowing the rotating plate 16 to rotate with the rotating rod 14, thus realizing the corresponding operation. The top of the rotating plate 16 is slidably connected to the bottom of the limiting plate 12. The sliding connection between the rotating plate 16 and the limiting plate 12 plays a key role in the installation and disassembly process. The connection and separation of the protective shell 1 and the bottom plate 2 are realized through the relative sliding of the two. The inner wall of the rotating plate 16 is provided with an installation groove 13, which facilitates the control of the rotation of the limiting plate 12. During disassembly, by rotating the limiting plate 12, the installation groove 13 on the inner wall of the rotating plate 16 passes through the outside of the limiting plate 12, thereby completing the disassembly between the protective shell 1 and the bottom plate 2. The outer wall of the rotating rod 14 is slidably connected to the inner wall of the installation groove 13. The rotating rod 14 slides on the inner wall of the installation groove 13, so that the rotation of the rotating rod 14 can drive the rotating plate 16 to move, thereby realizing the disassembly operation between the protective shell 1 and the bottom plate 2.

[0038] Working principle: When vibration damping of the synchronous motor 11 on the inner wall of the protective shell 1 is required, the screw 4 is rotated. The rotation of the screw 4 causes the slider 5 to slide towards each other on the outer wall of the screw 4. Then, the sliding of the slider 5 causes the connecting rod 6 at the bottom of the slider 5 to rotate. The rotation of the connecting rod 6 causes the connecting rod 6 to move downward. The rotation of the connecting rod 6 causes the fixed plate 8 to move downward. The downward movement of the fixed plate 8 causes the damper 9 and the bottom contact plate 10 to move downward until they contact the synchronous motor 11. When the synchronous motor 11 is running, it will generate vibration. At this time, the contact plate 10 will transmit the vibration to the damper 9. The damper 9 dissipates energy and suppresses vibration by converting the kinetic energy generated by vibration or impact into other forms of energy, thereby reducing the wear and fatigue of the motor caused by vibration and extending the service life of the motor bearings, windings and other components.

[0039] When the protective shell 1 needs to be removed, the limiting plate 12 is rotated. The mounting groove 13 facilitates the rotation of the limiting plate 12, which changes from horizontal to vertical. Then, the rotating plate 16 is rotated, causing it to be removed from the top of the limiting post 15. The mounting groove 13 on the inner wall of the rotating plate 16 passes through the outside of the limiting plate 12 once to complete the disassembly between the protective shell 1 and the base plate 2. This makes it easy to remove the protective shell 1 when the synchronous motor 11 is damaged, so that the synchronous motor 11 can be repaired. The heat dissipation port 3 is used to dissipate heat from the synchronous motor 11.
