[0028] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] In related technologies, a steering motor usually has a bus assembly installed in the axial direction of the motor. The copper wires extending from each winding of the motor are brought together through the bus and then connected to the circuit board. However, due to the limited space for the motor assembly position, the overall size of the bus assembly is large after assembly, which easily leads to difficulties in the space layout of the entire vehicle.

[0030] Reference below Figure 1-Figure 2 A steering motor according to an embodiment of the present invention is described.

[0031] According to the present invention, the steering motor 1 includes a motor housing 11, a winding 12 and a circuit board 13. The winding 12 is accommodated in the motor housing 11, and the winding 12 is provided with a plurality of output terminals 121 passing through the motor housing 11; the circuit board 13 is provided in the motor housing 11, and the circuit board 13 is provided with a connecting circuit. The connecting circuit has electrical connecting terminals corresponding to the plurality of output terminals 121 formed on the circuit board 13, and each electrical connecting terminal is connected to the corresponding output terminal 121.

[0032] According to the steering motor 1 of the present invention, a winding 12 is disposed within a motor housing 11. The winding 12 has an outlet terminal 121 formed thereon. A circuit board 13 is disposed within the motor housing 11. A connecting circuit having multiple electrical connection terminals is disposed within the circuit board 13. During assembly, the outlet terminals 121 of the winding 12 can be connected one-to-one with the electrical connection terminals of the circuit board 13. This allows the winding 12 to directly communicate with the connecting circuit within the circuit board 13, thereby achieving electrical connection of the steering motor 1. The connecting circuit herein can be simply understood as a combination circuit that replaces the function of a bus. Compared to the busbar method used in transmission motors, the steering motor 1 of the present invention eliminates the busbar structure transfer process by disposing the connecting circuit within the circuit board 13 and directly connecting the outlet terminals 121 of the winding 12 to the electrical connection terminals of the connecting circuit. This eliminates the need to consider busbar assembly during layout of the entire steering motor 1, reducing the size of the steering motor 1, simplifying the difficulty of arranging the steering motor 1 within the confined space of a vehicle, and improving the assembly efficiency of the steering motor 1.

[0033] According to one embodiment of the present invention, the winding 12 includes a three-phase winding, and the three-phase winding is constructed as a plurality of groups arranged at intervals along the circumferential direction in the motor housing 11; wherein each phase winding is provided with an outlet terminal 121 passing through the motor housing 11 and each phase winding is connected to a corresponding electrical connection terminal. The three-phase winding of the winding 12 is arranged at intervals along the circumferential direction in the motor housing 11, which can optimize the electromagnetic field distribution of the motor, so that the motor can generate a more uniform and smooth torque output when working, and can ensure the accuracy and stability of the vehicle steering operation. Each phase winding is provided with an outlet terminal 121 passing through the motor housing 11, and each phase winding is connected to a corresponding electrical connection terminal, which simplifies the connection process between the winding and the external power supply or control circuit, reduces the connection complexity and failure rate, and also facilitates the maintenance and replacement of the winding 12, thereby improving the maintainability of the motor.

[0034] According to one embodiment of the present invention, a motor housing 11 includes an outer shell 111 and an end cap 112. The outer shell 111 is arranged around a cavity to accommodate the winding 12. The end cap 112 is disposed at one end of the outer shell 111 and is provided with a circuit board 13. The end cap 112 is formed with a through hole 1121 for the outlet terminal 121 to pass through. The motor housing 11 is provided with the outer shell 111 and the end cap 112. The outer shell 111 defines the cavity to accommodate the winding 12, and the end cap 112 can seal the cavity. The outer shell 111 and the end cap 112 together form the structure of the motor housing 11, effectively encapsulating and protecting the internal components of the motor (i.e., the winding 12). The circuit board 13 is disposed on the end cap 112, allowing the circuit board 13 to be in close proximity to key components within the motor (such as the winding 12), facilitating direct signal transmission and control, reducing the complexity of wiring connections, and improving the reliability and efficiency of electrical connections. Furthermore, the circuit board 13 is located on the end cap 112, facilitating subsequent maintenance and replacement. The through-holes 1121 formed on the end cap 112, through which the outlet terminals 121 pass, provide a convenient passage for the wires of the motor windings 12, avoiding a cluttered arrangement of the wires within the motor housing 11. This ensures the secure fixing of the wires and facilitates connection to external devices, enhancing the overall aesthetics and electrical safety of the motor.

[0035] According to one embodiment of the present invention, an electrical connection terminal is provided on the side of the circuit board 13 facing away from the end cap 112. Placing the electrical connection terminal on the side of the circuit board 13 facing away from the end cap 112 allows for more efficient use of the space within the motor housing 11, preventing the electrical connection terminal from occupying the space between the end cap 112 and the circuit board 13. This allows for a more compact motor design or leaves more space for other key components, such as heat dissipation structures and seals.

[0036] According to one embodiment of the present invention, matching holes 131 corresponding to the through holes 1121 are formed on the circuit board 13, and the wire terminals 121 are connected to the electrical connection terminals after passing through the matching holes 131. Matching holes 131 corresponding to the through holes 1121 on the end cover 112 of the motor housing 11 are formed on the circuit board 13, so that the wire terminals 121 of the windings 12 can accurately pass through these matching holes 131 and be connected to the electrical connection terminals on the circuit board 13, avoiding misalignment or offset of the wire terminals 121 during the connection process, ensuring the accuracy and reliability of the electrical connection. At the same time, the design of the matching holes 131 makes the connection process of the wire terminals 121 smoother and more efficient. The wire terminals 121 do not need to be complicatedly bent or adjusted inside the motor housing 11, and can directly pass through the matching holes 131 to be connected to the electrical connection terminals, thereby simplifying the connection steps and reducing the difficulty of connection.

[0037] According to one embodiment of the present invention, the circuit board 13 is constructed as a circular plate symmetrical to the center of the end cover 112, and the electrical connection terminals are arranged at intervals on the outer periphery of the circuit board 13. Constructing the circuit board 13 as a circular plate symmetrical to the center of the end cover 112 can more effectively utilize the space inside the motor. The circular circuit board 13 can fit more closely on the end cover 112, reducing unnecessary space waste, thereby improving the compactness and integration of the entire motor. The electrical connection terminals are arranged at intervals on the outer periphery of the circuit board 13, which facilitates connection with external electrical components (such as power lines, control lines, etc.), which not only reduces the length and complexity of the connecting lines, reduces electrical losses and interference, but also improves the stability and reliability of the connection.

[0038] According to one embodiment of the present invention, the steering motor 1 also includes: a connecting row 14, a clamping groove 1431 that cooperates with the outlet terminal 121 is formed on the connecting row 14, and the connecting row 14 is welded to the electrical connection terminal. The clamping groove 1431 formed on the connecting row 14 can tightly clamp the outlet terminal 121 to ensure that the outlet terminal 121 does not loosen or fall off during the connection process. This design improves the stability and reliability of the connection and reduces electrical failures caused by poor connection. The welding of the connecting row 14 and the electrical connection terminal realizes the electrical connection between the outlet terminal 121 and the circuit board 13.

[0039] According to one embodiment of the present invention, the connector bar 14 includes a base 141, an extension 142, and a clamping arm 143. The base 141 is disposed on the side of the circuit board 13 facing away from the end cap 112 and has a support leg 1411 formed thereon. The extension 142 is disposed radially inwardly of the base 141 and extends away from the circuit board 13. The clamping arm 143 is configured as two arms, each connected to the extension 142. The two clamping arms 143 are radially spaced apart from the extension 142, and a clamping groove 1431 is formed between the two clamping arms 143. The base 141 is disposed on the side of the circuit board 13 facing away from the end cap 112 and has a support leg 1411 formed thereon. The support leg 1411 increases the mating area between the base 141 and the circuit board 13, thereby improving the stability of the connector bar 14 when assembled to the circuit board 13. The extension portion 142 is connected to the base 141, and a radially extending clamping arm 143 is provided at one end of the extension portion 142 facing away from the base 141. The extension portion 142 can be used to support the clamping arm 143, thereby increasing the stability of the connection row 14. Two clamping arms 143 are constructed, each connected to the extension portion 142 and extending radially away from the extension portion 142 to form a clamping groove 1431. During assembly, at least a portion of the outlet terminal 121 is firmly clamped in the clamping groove 1431, preventing the outlet terminal 121 from loosening or falling off due to vibration or external force. The shape and size of the clamping groove 1431 can be customized according to the shape and size of the outlet terminal 121 to provide an optimal clamping effect.

[0040] According to one embodiment of the present invention, an electrical unit 15 is formed on the side of the circuit board 13 facing away from the end cap 112. The electrical unit 15 is located radially inward of the electrical connection terminal. The electrical unit 15 (e.g., a capacitor) is located on the side of the circuit board 13 facing away from the end cap 112 and radially inward of the output terminal 121, effectively utilizing the space on the circuit board 13. When the steering motor 1 is assembled, the electrical unit 15 and the electrical connection terminal are located on the same side of the circuit board 13, minimizing the overall space occupied. This improves the compactness of the steering motor 1 and facilitates its layout.

[0041] In some embodiments, the circuit board 13 may be arranged perpendicular to the extension direction of the wire-outlet end 121 , so that the wire-outlet end 121 can pass through the matching hole 131 on the circuit board 13 .

[0042] In some embodiments, the circuit board 13 can also be constructed into a square or other shape. At the same time, the circuit board 13 can be reasonably arranged according to the actual size and design of the battery shell. It is not limited to the arrangement of the circuit board 13 perpendicular to the output terminal 121. It can also be parallel or at other angles. At this time, the output terminal 121 can directly bypass the radial outer edge of the circuit board 13 and connect to the connection row 14 on the circuit board 13.

[0043] In some embodiments, the outgoing wire end 121 can be directly connected with the connecting circuit inside the circuit board 13 when passing through the matching hole 131, without the need to set the connecting row 14 as an adapter between the outgoing wire end 121 and the electrical connection end.

[0044] In some embodiments, the electrical connection end can be simply understood as a welding point or the like structure when the connecting row 14 is welded with the circuit board 13.
