Description

Technical Field

[0001] This utility model relates to the field of motorcycle motor technology, and in particular to a stator frame for a motorcycle motor. Background Technology

[0002] Motorcycle magnetoes mainly consist of a stator and a rotor. The stator includes a stator core and coils. The stator core is typically formed by stacking and riveting several stator laminations together. The stator laminations have a central mounting section and evenly distributed T-shaped winding teeth on the outer edge. These stacked laminations form T-shaped winding teeth on the outer edge of the core. Insulating material is then injected into the outer surface of the core, and finally, coils are wound around the winding teeth on the outer edge of the stator core to form the magneto stator. Currently, the stator laminations for the stator core are stamped as a single piece, resulting in significant material loss due to stamping, low material utilization, and high material costs.

[0003] The utility model patent with publication number CN203166639U provides a stator core for a magneto, including stator laminations, baffle laminations, and an insulating frame that are stacked together. The main body of the stator laminations is octagonal with a positioning hole in the middle, and a T-shaped winding tooth is provided in the middle of each side. The baffle laminations are located at both ends of the stator laminations and their shapes correspond to the adjacent stator laminations. The insulating frame covers the winding tooth stack formed by the stator laminations and the baffle laminations. The stator laminations are composed of eight interlocking sub-laminations. The stator laminations are interlocked by dovetail grooves, which are located on the line connecting the corner of the octagon and the center of the positioning hole. An anchor hole is provided at the end of the sub-lamination closest to the positioning hole to improve the tightness of the connection between the sub-laminations and facilitate the stacking and assembly of the stator laminations.

[0004] The stator laminations of the above scheme consist of eight interlocking sub-lamps. Adjacent sub-lamps are interlocked by dovetail grooves. Although this can connect adjacent sub-lamps, the sub-lamps are prone to misalignment, which affects their use. Utility Model Content

[0005] The purpose of this utility model is to provide a wire frame for a motorcycle motor stator, which solves the problem that although the dovetail groove can connect adjacent sub-lamps, the sub-lamps are prone to misalignment, thus affecting the use.

[0006] To achieve the above objectives, this utility model provides a wire frame for a motorcycle motor stator, including a winding tooth and a lamination assembly. The lamination assembly includes multiple sub-lamps and multiple connecting frames. The multiple sub-lamps are connected end-to-end to form a circle. Each sub-lamp has a winding tooth on its outer side, which is integrally formed with the sub-lamp. The connecting frame includes a connecting portion and two engaging portions. The two engaging portions are integrally formed with the connecting portion and are located at both ends of the connecting portion. Both engaging portions are perpendicular to the connecting portion. Each sub-lamp has a slot and a placement cavity. The placement cavity communicates with the slot and extends to the edge of the sub-lamp. The connecting portion is located inside the placement cavity. The two engaging portions of the connecting frame are located in the slots of two adjacent sub-lamps.

[0007] The sub-punch piece has a spherical connecting block on one side and a spherical connecting groove on the other side that is adapted to the spherical connecting block. The spherical connecting block of the sub-punch piece is located in the spherical connecting groove of the adjacent sub-punch piece.

[0008] The punch assembly further includes a positioning shaft, and the inner side of each sub-punch is arc-shaped, with the positioning shaft located inside each sub-punch.

[0009] The sub-punch piece is provided with a positioning bracket on its inner side, and the positioning shaft is provided with a plurality of positioning grooves that are adapted to the positioning bracket at intervals on its circumference. The positioning bracket of each sub-punch piece is located inside the respective positioning groove.

[0010] The sub-punch piece is provided with two through holes, which are spaced apart and symmetrically arranged on both sides of the sub-punch piece.

[0011] This utility model discloses a stator frame for a motorcycle motor. Two engaging parts respectively engage with the slots of two adjacent sub-lamps, thereby fixing the two adjacent sub-lamps together and preventing them from falling off. Due to the connecting frame, the two adjacent sub-lamps will not easily misalign. This solves the problem that while dovetail joints can connect adjacent sub-lamps, misalignment can easily occur, affecting usability. Attached Figure Description

[0020] This utility model provides a wire frame for a motorcycle motor stator, including winding teeth 110 and a lamination assembly. The lamination assembly includes multiple sub-lamps 120, multiple connecting frames, and a positioning round shaft 140.

[0021] In this specific embodiment, multiple sub-punches 120 are connected end to end to form a circle. A winding tooth 110 is provided on the outer side of each sub-punch 120.

The two engaging portions 132 of the connecting frame are located in the slots 121 of two adjacent sub-punches 120. The winding teeth 110 are disposed on the outer side of the sub-punch 120, and the winding teeth 110 are integrally formed with the sub-punch 120. The connecting bracket is used to connect two adjacent sub-punch 120s. The two engaging portions 132 are respectively arranged perpendicularly to the connecting portion 131, and the engaging portions 132 are both integrally formed with the connecting portion 131. The placement cavity 122 is used to accommodate the connecting portion 131, and the slot 121 is used to accommodate the engaging portion 132. The two engaging portions 132 are respectively The two adjacent sub-punches 120 are engaged in the slots 121 of each other, thereby fixing the two adjacent sub-punches 120 together and preventing them from falling off. Due to the function of the connecting bracket, the two adjacent sub-punches 120 will not easily become misaligned. This solves the problem that although the dovetail joint can connect the adjacent sub-punches 120, they are prone to misalignment, which affects their use.

[0022] Furthermore, a spherical connecting block 123 is provided on one side of the sub-punch piece 120, and a spherical connecting groove 124 adapted to the spherical connecting block 123 is provided on the other side of the sub-punch piece 120.

The spherical connecting block 123 is located inside the spherical connecting groove 124, and the spherical connecting block 123 and the spherical connecting groove 124 cooperate with each other to improve the connection stability between two adjacent sub-punch pieces 120. Moreover, the cooperation between the spherical connecting block 123 and the spherical connecting groove 124 can position the two sub-punch pieces 120 to facilitate the installation of the sub-punch pieces 120. When it is necessary to connect two adjacent sub-punches 120, the spherical connecting block 123 is aligned with the spherical connecting groove 124 and inserted to connect the two adjacent sub-punches 120.

The positioning bracket 125 of each sub-punch piece 120 is located inside the respective positioning groove 141. When installing the sub-punch piece 120 onto the positioning shaft 140, the positioning bracket 125 is aligned with the positioning groove 141 and inserted to position the sub-punch piece 120. The positioning bracket 125 and the positioning groove 141 cooperate to position the sub-punch piece 120, thereby facilitating its fixation.

[0025] In addition, the sub-punch piece 120 is provided with two through holes 126, which are spaced apart and symmetrically arranged on both sides of the sub-punch piece 120.
