From a professional perspective, electric motors primarily operate based on the principle of electromagnetic induction, and their core components typically include a stator, rotor, and electromagnetic windings. In an electric motor, the stator, as the stationary part, is usually equipped with electromagnetic windings to generate a rotating magnetic field. The rotor, as the rotating part, rotates due to the force exerted by the rotating magnetic field through electromagnetic induction, thereby converting electrical energy into mechanical energy. Furthermore, electric motors come in various types to adapt to different application scenarios.

[0003] Direct-drive motors typically require an internal control board. Existing control boards are secured with screws during assembly, but the relatively complex internal structure of the motor makes installation difficult. Therefore, a new design is needed to address the limitations of the existing control board mounting structure. Utility Model Content

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0026] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-5As shown, in one embodiment of this utility model, a circuit board mounting structure is provided, including a base 1, a stator assembly 2, and a control board 3. The stator assembly 2 is disposed on the base 1, and the stator assembly 2 is provided with a stator frame 21. A support frame 4 is provided at one end of the stator frame 21. The support frame 4 includes an inner support member 41 and an outer support member 42 disposed on the stator frame 21. The end faces of the inner support member 41 and the outer support member 42 are flush. A fixing element 43 and a positioning element 44 are provided on the support frame 4. The control board 3 is disposed on the support frame 4. The positioning element 44 is used for mounting and positioning the control board 3, and the fixing element 43 is used for fixing the control board 3 to the support frame 4. In terms of installation convenience, the positioning element 44 improves the installation efficiency of the control board 3. Because the positioning element 44 accurately positions the control board 3, the staff can quickly place the control board 3 in the accurate position during the assembly process, reducing the time and effort spent on repeated adjustments and alignment. Precise positioning makes the installation and operation of the control board 3 simple and straightforward, allowing even beginners to quickly get started and effectively shortening the overall assembly cycle of the motor. In terms of stability, the inner support member 41 and the outer support member 42 of the support frame 4 are relatively flush, providing a stable support foundation for the control board 3 and ensuring that the control board 3 will not shift due to vibration or other factors during motor operation. At the same time, the fixing element 43 firmly fixes the control board 3 to the support frame 4, further enhancing stability. Even when the motor is in a high-speed, complex vibration environment for extended periods, the control board 3 can maintain a stable connection, avoiding problems such as poor contact and abnormal signal transmission caused by loosening, ensuring the reliable operation of the motor control system, reducing the probability of failures caused by circuit board instability, and improving the overall stability and reliability of the motor.

[0028] One end of the base 1 is provided with an end cap 11, and the other end is provided with a mating step 12. The stator frame 21 is mounted on the mating step 12. Specifically, the mating step 12 is provided with a wiring groove 121, one end of which is connected to the control board 3, and the other end is connected to and passes through the end cap 11. In this embodiment, the base 1 has an end cap 11 at one end and a mating step 12 at the other end. This layout makes the installation position of the stator frame 21 clear and the fixing method simple. Workers can quickly and accurately install the stator frame 21 on the mating step 12, reducing the adjustment steps during installation and effectively improving assembly efficiency. At the same time, the wiring groove 121 on the mating step 12 is cleverly designed, with one end connected to the control board 3 and the other end connected to and passing through the end cap 11, providing a dedicated channel for the internal wiring of the motor, avoiding messy wiring. Installers can easily perform wiring operations along the wiring groove 121, further improving installation convenience. In terms of stability, the step 12 provides stable support for the stator frame 21, ensuring that it will not shift during motor operation. The wiring trough 121 protects and positions the wiring, preventing it from loosening or shifting due to motor vibration or other factors, thus ensuring the stability of the circuit connection.

[0029] The stator frame 21 is provided with multiple stator arms 211, which are evenly distributed circumferentially on the outer periphery of the stator frame 21. The outer support member 42 is disposed at the end of the stator arms 211. Specifically, the inner support member 41 is arranged in a ring on the stator frame 21, and the outer support member 42 is formed by multiple support blocks 421 continuously arranged circumferentially on the stator arms 211. In this embodiment, the multiple evenly distributed circumferential stator arms 211 provide clear and regular positioning points for the installation of the circuit board, enabling the circuit board to quickly and accurately align with the stator arms 211, reducing alignment time and operational difficulty during installation. Simultaneously, the inner support member 41 is arranged in a ring on the stator frame 21, and the outer support member 42 is formed by multiple support blocks 421 continuously arranged circumferentially on the stator arms 211; this combined internal and external support method greatly enhances structural stability. The inner support 41 stabilizes the internal structure of the stator frame 21, while the outer support 42 reinforces the stator winding arm 211 at its ends, ensuring that the components maintain relative stability even when the stator is running at high speed. Installing the circuit board on this stable structure effectively prevents problems such as loose connections and poor contact caused by stator vibration.

[0030] The fixing element 43 is configured as a fixing buckle 431, and the control plate 3 is provided with a fixing slot 31. The fixing buckle 431 is used to fix the control plate 3 onto the support frame 4. Specifically, the positioning element 44 is a positioning pin 441, and the control plate 3 is provided with a positioning hole 32. The positioning hole 32 is used to cooperate with the positioning pin 441, and the end of the positioning pin 441 is chamfered. In this embodiment, the fixing buckle 431 firmly fastens the control plate 3 onto the support frame 4, greatly improving the convenience of installation. Compared with the traditional installation method, there is no need for complicated screw tightening operations, and the staff can quickly complete the installation of the control plate 3, effectively shortening the assembly time and improving production efficiency. The cooperation between the positioning pin 441 and the positioning hole 32 further enhances the stability of the installation. The chamfered design at the end of the positioning pin 441 makes the positioning pin 441 smoother when inserted into the positioning hole 32, accurately guiding the control plate 3 to the predetermined position and avoiding displacement during the installation process. This ensures a precise connection between the control board 3 and the support frame 4, preventing the control board 3 from becoming loose due to vibration or other factors during motor operation. This improves the overall stability and reliability of the motor and reduces malfunctions caused by the loosening of the control board 3.

[0031] Furthermore, the fixing buckle 431 is provided with an inclined surface. There are two sets of fixing buckles 431; one set has its inclined surface facing the base 1, and the other set has its inclined surface facing away from the base 1, to achieve radial fixation. Specifically, the fixing buckle 431 with its inclined surface facing the base 1 is located on the outer support member 42, and the fixing buckle 431 with its inclined surface facing away from the base 1 is located on the inner support member 41, thereby achieving radial fixation. This further ensures the stability of the control plate 3.

[0032] An electric motor includes the aforementioned circuit board mounting structure. A cavity 13 is provided at the center of the base 1, and a shaft assembly 5 is disposed within the cavity 13. The shaft assembly 5 is connected to a rotor assembly 6. The rotor assembly 6 includes a rotor housing 61 and a rotor element 62. The rotor element 62 is disposed within the rotor housing 61 and is opposite to the rotor assembly 6. This embodiment, combined with the aforementioned circuit board mounting structure, simplifies the circuit board installation process. It enables quick and accurate positioning of the circuit board, reducing adjustment time and operational difficulty during installation. Installers can quickly complete the installation and fixation of the circuit board, significantly improving the efficiency of overall motor assembly and shortening the production cycle. The cavity 13 at the center of the base 1 reasonably accommodates the shaft assembly 5, providing solid support for the stable operation of the entire rotor assembly 6. The reliable connection between the shaft assembly 5 and the rotor assembly 6 ensures the stability of power transmission. The rotor element 62 is securely disposed within the rotor housing 61, and its relative position to related components is precise, reducing vibration and offset during rotor operation. The coordinated design of the circuit board mounting structure with other parts of the motor ensures that the circuit board can work stably during motor operation, unaffected by factors such as vibrations generated by rotor rotation. This guarantees the accurate transmission and processing of motor control signals, thereby improving the overall stability of the motor performance, reducing the failure rate caused by component instability, and extending the service life of the motor.

[0033] The rotating shaft assembly 5 includes a bearing component 51 and a rotating shaft 52. The bearing component 51 is disposed within the cavity 13, and the rotating shaft 52 is disposed on the bearing component 51. One end of the rotating shaft 52 is provided with a connector 53, and the rotating shaft 52 is connected to the rotor housing 61 through the connector 53. In this embodiment, the fixing buckle 431 and the circuit board mounting structure cooperate with each other to form an efficient and simple assembly process. The operator only needs to align the control board 3 with the corresponding position of the support frame 4 and use the buckle to fasten it, which greatly reduces the skill requirements for the installation personnel. The positioning pin 441, the positioning hole 32, and the stabilizing components in the circuit board mounting structure work together to ensure the accurate positioning of the control board 3 from a planar perspective and enhance the constraint on the control board 3 in three-dimensional space. Even if the motor operates under complex conditions for a long time and is subjected to large vibrations and impacts, the control board 3 can remain stable.

[0034] An end cap 11 is provided at one end of the base 1. A mounting portion 111 is provided on the outer side of the end cap 11, and the mounting portion 111 has mounting holes 112. A retaining ring 113 is provided on the end cap 11. One end of the rotor housing 61 extends to the retaining ring 113, and the inner diameter of the rotor housing 61 is opposite to the outer diameter of the retaining ring 113. In this embodiment, the mounting hole 112 on the outer side of the mounting portion 111 of the end cap 11 at one end of the base 1 provides a precise and convenient positioning point for the overall installation of the motor, enabling rapid docking and fixing of the motor with other components, greatly shortening installation time. The retaining ring 113 on the end cap 11, in conjunction with the extension at one end of the rotor housing 61, ensures accurate installation of the rotor housing 61 while further simplifying the installation process, making the installation operation smoother and more efficient.

[0035] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
