Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a motor end cover. Background Technology

[0002] In the field of motor technology, the motor end cover, as an important component of the motor, not only serves to protect the internal structure of the motor, but also often integrates conductive components to achieve electrical connections between the internal electrical components. With the continuous development of motor technology, the requirements for motor performance are also increasing, especially in terms of conductivity and stability.

[0003] In traditional motor end cover designs, the layout and connection methods of conductive components are often quite complex. The current transmission path between electrical components such as circuit boards, conductive sheets, and inductors is relatively long, which not only increases the resistance of current transmission but also easily leads to problems such as poor contact and increased resistance, thereby affecting the conductivity and stability of the motor. These problems may be more pronounced, especially when the motor is running at high speed or for extended periods, and may even cause motor failure or damage.

[0004] Furthermore, as motors become smaller and more integrated, the space inside the motor end cover is becoming increasingly limited. Achieving efficient and stable electrical connections within this limited space has become a significant challenge in motor end cover design. Summary of the Invention

[0005] This application provides a motor end cover in which a conductive part abuts against a conductive block, so that one end of an inductor is electrically connected to the conductive block through the conductive part. The direct abutment between the conductive block and the conductive part can ensure that the transmission of current between the circuit board, the first conductive sheet, and the inductor is more direct and efficient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a motor end cover, comprising:

[0007] End cap body, the end cap body is provided with a cavity;

[0008] A conductive component is disposed within a cavity. The conductive component includes a circuit board disposed at one end of the cavity, two first conductive plates symmetrically disposed at one end of the circuit board, an inductor disposed on both sides of the cavity, and a second conductive plate disposed at one end of the inductor. A conductive block is disposed at one end of the circuit board near the first conductive plate. The first conductive plate includes a conductive part vertically disposed corresponding to the conductive block. The conductive part abuts against the conductive block so that one end of the inductor is electrically connected to the conductive block through the conductive part, and the other end of the inductor is electrically connected to the second conductive plate.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] The conductive part abuts against the conductive block so that one end of the inductor is electrically connected to the conductive block through the conductive part. The direct contact between the conductive block and the conductive part ensures that the current transmission between the circuit board, the first conductive sheet, and the inductor is more direct and efficient, making the current transmission process more stable. This helps to improve the conductivity and stability of the entire circuit. In addition, the use of multiple inductors can form a more complex circuit structure, which helps to suppress high-frequency noise and electromagnetic interference in the circuit, thereby improving the stability and reliability of the circuit. The inductor has the function of energy storage and filtering. Multiple inductors can work together to better smooth power supply voltage fluctuations and provide a stable power supply environment for the motor.

[0011] As an improvement, the cavity is provided with an inductor mounting slot for accommodating an inductor, a first electrode mounting slot for accommodating a first conductive sheet, and a second electrode mounting slot for accommodating a second conductive sheet on both sides. The first electrode mounting slot, the inductor mounting slot, and the second electrode mounting slot are connected in sequence. By connecting the first electrode mounting slot, the inductor mounting slot, and the second electrode mounting slot in sequence, the inductor and conductive sheet can be arranged more rationally within the limited cavity space, making the entire structure more compact.

[0012] As an improvement, the first conductive sheet also includes an abutment portion that is perpendicularly connected to the conductive part. One side of the abutment portion abuts against the side wall of the electrode mounting groove. The abutment design between the abutment portion and the side wall of the electrode mounting groove provides a stable support point for the first conductive sheet, which helps to prevent the conductive sheet from shifting during installation and use, thereby ensuring the stability and reliability of the circuit connection.

[0013] As an improvement, a grounding wire is provided on the side of the circuit board near the end cover body extending outward. A relief groove is provided on the outer wall of the end cover body corresponding to the grounding wire. The grounding wire is at least partially attached to the bottom surface of the relief groove. By providing a grounding wire on the side of the circuit board near the end cover body extending outward and utilizing the relief groove on the outer wall of the end cover body, the grounding wire can be tightly fitted into the relief groove, thereby saving valuable space and improving the compactness of the overall structure.

[0014] As an improvement, a bearing seat is provided at the center of the cavity, and a brush holder is provided on one side of the second conductive plate, extending to the side near the bearing seat. The brush holders are symmetrically arranged, and the other end of the inductor is electrically connected to the brush holder through the second conductive plate. A brush is installed at the end of the brush holder. The symmetrical arrangement of the brush holders ensures the balance of the brush under force, reducing vibration and noise caused by uneven force.

[0015] As an improvement, the second conductive sheet includes a connecting portion. On the side of the connecting portion near the brush holder, a plurality of limiting grooves are provided along the brush holder. The upper and lower ends of the brush holder abut against the sidewalls of the limiting grooves. The tight fit between the limiting grooves and the upper and lower ends of the brush holder provides a stable support and positioning for the brush holder, which helps to prevent the brush holder from shifting or loosening under vibration or external force, thereby ensuring the stability and reliability of the circuit connection.
