Description

Technical Field

[0001] This utility model relates to the field of motor stator assembly, specifically to a novel vehicle balance motor stator assembly. Background Technology

[0002] The motor stator assembly is a key component of the vehicle's balancing system, and its performance directly affects the vehicle's stability and handling. Traditional ESC motor stator assemblies present numerous assembly challenges, such as complex assembly processes and high requirements for magnet strength and clearance dimensions. This not only increases production costs but also impacts the overall performance and lifespan of the motor. Especially during vehicle operation, if the motor stator assembly is accidentally dropped or impacted, the magnets are highly susceptible to breakage, leading to motor malfunction and posing a safety hazard. Furthermore, the existing structural design makes the stator assembly prone to shock absorption, detachment (the elasticity weakens over time), and magnet breakage. Summary of the Invention

[0003] In view of this, the present invention provides a novel vehicle balancing motor stator assembly.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A novel vehicle balancing motor stator assembly includes a housing, a magnet, and a carbon brush cover assembly. The magnet is disposed inside the housing, and the carbon brush cover assembly covers the top of the housing. A retainer is also disposed inside the housing, and the magnet is disposed on the retainer. The retainer cooperates with the inner wall of the housing to limit and fix the magnet.

[0005] Preferably, the retainer includes a retainer body and a plurality of support members disposed on the retainer body. The retainer body includes a top plate, a base and a connecting column disposed between the top plate and the base. The support members are disposed on the top plate. A magnet is disposed between two adjacent support columns on the retainer body and the magnet is embedded in the retainer body.

[0006] Preferably, the connecting post also has a protruding positioning part, which is attached to the magnets at both ends of the connecting post to limit the position of the magnets.

[0007] Preferably, the magnet is connected to the connecting posts on both sides of the magnet, and the connecting posts limit the movement of the magnet toward a position closer to the center of the cage body.

[0008] Preferably, the carbon brush cover assembly includes a carbon brush cover, a carbon brush holder, and a plug terminal. The carbon brush cover is disposed on the housing, and a fixing groove for a corresponding support member is formed on the side of the carbon brush cover near the magnet. The support member extends into the fixing groove so that the carbon brush cover is supported by the retainer.

[0009] Preferably, the carbon brush box is located on the side of the carbon brush cover near the retainer, and the insert terminal is located on the side of the carbon brush cover away from the housing.

[0010] Preferably, the housing is further provided with a slot, and the carbon brush cover is provided with a connecting end protruding at the position corresponding to the slot. The connecting end extends into the slot so that the carbon brush cover is connected to the housing.

[0011] Preferably, the housing is further provided with mounting holes, through which the housing is connected to the outside.

[0012] Preferably, a bearing is also provided on the bottom wall of the housing.

[0013] The beneficial effects of this invention are as follows: This design effectively solves the problems of complex assembly and high requirements for magnet strength and clearance dimensions in the original ESC motor stator assembly by setting a cage. The cage design not only simplifies the assembly process and reduces reliance on fixtures, but also significantly improves the shock resistance of the stator assembly and the stability of the magnets. In the event of accidental drops or collisions, the cage can disperse the impact force, reducing the force acting directly on the magnets, thereby effectively preventing magnet breakage and extending the service life of the motor. In addition, the fit and limiting between the cage and the inner wall of the housing ensures the accuracy of the magnet position, improving the stability and efficiency of motor operation.

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.

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] This utility model provides the following technical solution: As attached Figure 1-9 As shown, this utility model discloses a novel vehicle balancing motor stator assembly. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] This utility model provides the following technical solution: As attached Figure 1-9As shown, this utility model discloses a novel stator assembly for a vehicle balancing motor, including a housing 1, a magnet 2, and a carbon brush cover assembly 3. The magnet 2 is disposed inside the housing 1, and the carbon brush cover assembly 3 covers the housing 1. A retainer 4 is also disposed inside the housing 1, and the magnet 2 is mounted on the retainer 4. The retainer 4, in conjunction with the inner wall of the housing 1, limits and fixes the magnet 2. In this embodiment, the retainer 4 serves to precisely position and stably support the magnet 2. Through its unique structural design, the retainer 4 not only firmly fixes the magnet 2 inside the housing 1, preventing displacement or loosening during motor operation, but also ensures the accuracy of the magnet 2's position. Meanwhile, a frame structure 5 is provided inside the cage 4, and the magnet 2 is placed inside the frame structure 5. This design ensures that if the housing 1 is accidentally detached or impacted, the magnet 2 can still be effectively protected inside the frame structure 5, preventing it from scattering or being damaged due to changes in the housing 1, thus guaranteeing the service life of the magnet 2. This greatly improves the reliability and durability of the motor stator assembly, and increases the vibration resistance and stability of the stator assembly. In addition, the design of the frame structure 5 also considers the uniform distribution of the magnetic field. By rationally arranging the positions of the support 7 and the magnet 2, the motor can generate a stable and uniform magnetic field during operation, thereby improving the overall performance of the motor. Furthermore, the installation process of this motor stator assembly involves first placing the magnet 2 into the cage 4, and then pressing the cage 4 into the housing 1. This installation process solves the problem of excessively high installation precision required for the magnet 2 in existing motor stator assemblies. In addition, the motor stator assembly in this embodiment replaces the spring clips in the original housing 1, making the motor stator more vibration-resistant, less prone to detachment, and the magnet 2 less likely to be damaged. In this embodiment, the cage 4 is made of plastic.

[0022] Furthermore, the retainer 4 includes a retainer body 6 and several support members 7 disposed on the retainer body 6. The retainer body 6 includes a top plate 8, a base 9, and a connecting post 10 disposed between the top plate 8 and the base 9. The support members 7 are disposed on the top plate 8. A magnet 2 is disposed between two adjacent support posts on the retainer body 6, and the magnet 2 is embedded in the retainer body 6. In this embodiment, the retainer 4 serves to further refine the installation and positioning of the magnet 2. Its top plate 8 and base 9 are firmly connected by the connecting post 10 to form a frame, providing a reliable support foundation for the magnet 2. The support members 7 are distributed on the top plate 8, strengthening the connection with the carbon brush cover assembly 3, providing additional support for the carbon brush cover assembly 3, ensuring the stability and reliability of the overall electronic assembly. At the same time, the structure of the retainer 4 also ensures the uniformity and stability of the magnetic field. The design of embedding the magnet 2 in the retainer body 6 further prevents the magnet 2 from vibrating and shifting during motor operation, improving the smoothness and reliability of motor operation. At the same time, this embedded installation method also simplifies the assembly process and improves production efficiency. In this embodiment, both the top plate 8 and the base 9 are arranged in annular hollow structures.

[0023] Furthermore, a positioning part 11 protrudes from the connecting column 10, and the positioning part 11 is fitted with the magnets 2 at both ends of the connecting column 10 to define the position of the magnets 2. In this embodiment, the positioning part 11 functions to precisely position the magnets 2 axially. The tight fit between the positioning part 11 and the magnets 2 effectively prevents axial movement of the magnets 2 during motor operation, thus ensuring the stability and accuracy of the magnets 2's position. This design not only improves the motor's performance but also extends its service life, as a stable position of the magnets 2 helps reduce motor malfunctions and wear caused by magnet 2 displacement. Simultaneously, the protruding positioning part 11 also increases the structural strength of the cage 4, enabling it to better withstand various forces and vibrations generated during motor operation.

[0024] Furthermore, the magnet 2 is connected to the connecting posts 10 on both sides of the magnet 2, and the connecting posts 10 limit the movement of the magnet 2 towards the center of the cage body 6. In this embodiment, the limiting function of the connecting posts 10 ensures the stability of the magnet 2 in the radial direction, preventing it from shifting when operating at high speed or subjected to external impact. At the same time, the cage 4 limits the magnet 2, preventing it from being removed from the side near the center of the cage 4, and allowing it to be installed and removed only from the side near the inner wall of the housing 1. This enhances the stability of the magnet 2 on the cage 4 and makes it easier to limit and fix the magnet 2 in conjunction with the housing 1. When the magnet 2 installed on the cage 4 is installed into the housing 1, one side of the magnet 2 is doubly limited radially and axially by the cage 4, while the other side is further stabilized by the fit against the inner wall of the housing 1. This design greatly improves the fixing effect of the magnet 2 inside the motor. When the motor rotates at high speed or encounters a sudden external force, magnet 2 can maintain its original position and posture, and will not be displaced or detached due to centrifugal force or impact force, thus ensuring the stability and safety of motor operation. This design not only improves the structural strength of the motor stator assembly, but also enables magnet 2 to maintain a precise radial position during operation, thereby ensuring the stability and uniformity of the motor's magnetic field. At the same time, due to the radial limiting of magnet 2 by connecting column 10, the vibration and noise generated by the motor during operation are also effectively reduced, further improving the overall performance and user experience of the motor. In this embodiment, magnet 2 is arranged in an arc-shaped sheet structure, which can fit the arc-shaped design of cage 4, while providing space for the rotating parts in the middle.

[0025] Furthermore, the carbon brush cover assembly 3 includes a carbon brush cover 12, a carbon brush holder 13, and insert terminals 14. The carbon brush cover 12 is disposed on the housing 1, and a fixing groove 15 corresponding to the support member 7 is formed on the carbon brush cover 12. The support member 7 extends into the fixing groove 15 so that the carbon brush cover 12 supports the cage 4. In this embodiment, the function of the carbon brush cover 12 is to provide a stable top sealing structure for the motor stator assembly, and at the same time, through the support cooperation with the cage 4, it ensures the stability and reliability of the overall structure. The fixing groove 15 on the carbon brush cover 12 corresponding to the support member 7 not only enhances the connection strength between the carbon brush cover 12 and the cage 4, but also enables precise alignment of the two during assembly, improving assembly efficiency and accuracy. In addition, this design effectively disperses the vibration and stress generated during motor operation, preventing structural damage or performance degradation caused by local stress concentration. The carbon brush box 13 and the insert terminal 14 further enhance the function of the carbon brush cover assembly 3. The carbon brush box 13 provides a stable installation space for the carbon brush and the spring, ensuring good contact between other components (such as the converter), thereby ensuring the normal operation of the motor. The insert terminal 14 facilitates the connection between the motor stator assembly and the external circuit, improving the practicality and maintainability of the motor.

[0026] Furthermore, the carbon brush holder 13 is located on the side of the carbon brush cover 12 near the retainer 4, and the insert terminal 14 is located on the side of the carbon brush cover 12 away from the housing 1. In this embodiment, the carbon brush holder 13 provides a stable mounting position for the carbon brushes close to the core of the motor. This layout ensures that the carbon brushes maintain continuous and stable contact with the commutator during motor operation, thereby effectively transmitting current and ensuring the normal operation of the motor. At the same time, since the carbon brush holder 13 is close to the retainer 4, it is also convenient to inspect and replace the carbon brushes in a timely manner, improving the convenience of motor maintenance. The insert terminal 14 is located on the side of the carbon brush cover 12 away from the housing 1, which facilitates the quick connection and disconnection of the motor stator assembly with external circuits. When it is necessary to repair or replace the motor, the connection between the insert terminal 14 and the external circuit can be quickly disconnected without the need for complex disassembly of the motor stator assembly, thereby greatly improving maintenance efficiency. In addition, the setting of the insert terminal 14 also makes the motor stator assembly more flexible and reliable when connecting to external circuits, and can adapt to different circuit layouts and connection requirements.

[0027] Furthermore, the housing 1 is provided with a slot 16, and the carbon brush cover 12 has a connecting end 17 protruding from the slot 16. The connecting end 17 extends into the slot 16 to connect the carbon brush cover 12 to the housing 1. In this embodiment, the slot 16 provides a precise and stable positioning structure for the connection between the carbon brush cover 12 and the housing 1. By providing a slot 16 on the housing 1 and a corresponding connecting end 17 on the carbon brush cover 12, quick and reliable assembly is achieved. This design not only simplifies the assembly process and improves production efficiency, but also ensures the connection strength and stability between the carbon brush cover 12 and the housing 1. During motor operation, the cooperation of the slot 16 and the connecting end 17 can effectively disperse and withstand vibration and stress, preventing the carbon brush cover 12 from loosening or falling off due to vibration, thereby ensuring the overall performance and reliability of the motor stator assembly. At the same time, this connection method also facilitates subsequent maintenance and disassembly, reducing maintenance costs and time.

[0028] Furthermore, the housing 1 is also provided with mounting holes 18, through which the housing 1 is connected to the outside. In this embodiment, the mounting holes 18 provide a convenient and reliable connection method for fixing the motor stator assembly to the external equipment. By providing mounting holes 18 on the housing 1, the motor stator assembly can be firmly installed on the external equipment using bolts or other fasteners, ensuring the stability and reliability of the motor during operation. This design not only simplifies the installation process and improves installation efficiency, but also allows the motor stator assembly to adapt to different installation environments and requirements. At the same time, the mounting holes 18 also facilitate subsequent maintenance and replacement. When the motor needs repair or replacement, the motor stator assembly can be quickly separated from the external equipment by disassembling the fasteners, reducing maintenance difficulty and cost. In addition, the position and number of mounting holes 18 can be flexibly adjusted according to actual needs to meet the installation requirements of different equipment.

[0029] Furthermore, a bearing 19 is also provided on the bottom wall of the housing 1. In this embodiment, the bearing 19 provides stable and low-friction rotational support for the motor stator assembly. The bearing 19, located on the bottom wall of the housing 1, can withstand the radial and axial loads generated during motor operation, ensuring that the motor rotor can rotate smoothly and efficiently. This design not only reduces friction and wear during motor operation, improving motor operating efficiency and lifespan, but also reduces performance degradation caused by vibration and noise.
