In this embodiment, the adaptor 30 is used as a connection structure of the flexible electrical connection wire 12 and the conductive post 20, and after the flexible electrical connection wire 12 and the conductive post 20 are respectively connected with the adaptor 30, the flexible electrical connection wire 12 and the conductive post 20 can be electrically connected through the adaptor 30. Because the adaptor 30 is provided with the positioning groove 31, the positioning groove 31 can limit the flexible electric connecting wire 12, so that the flexible electric connecting wire 12 can be accurately positioned with the positioning groove 31 and can be welded well, and the welding is convenient and reliable. Meanwhile, the flexible electric connection wire 12 is arranged in the positioning groove 31 and wrapped by the groove wall of the positioning groove 31, and compared with the contact area of the flexible electric connection wire 12 and the conductive column 20 in the traditional scheme, the contact area of the flexible electric connection wire 12 and the groove wall of the positioning groove 31 is larger, the welding area is wider, and the welding effect is better.

In this embodiment, the base 40 is concave in the middle and convex on both sides, for example, in an arch shape, and the adapter 30 is centrally disposed in the concave position of the base 40, i.e., the center 43, so that the adapter 30 can fully utilize the space similar to the groove formed in the middle of the base 40 to perform the arrangement, thereby avoiding additional space occupation, and thus, when the adapter 30 is added, the volume of the whole motor module is not increased. Meanwhile, the stator coil, the flexible electric connecting wire, the adapter and the conductive column are basically connected from top to bottom in sequence, are orderly and compact in arrangement, and can be conveniently assembled in sequence along the same direction, and meanwhile, can avoid overlarge transverse dimension. Thus, the motor module is arranged by fully utilizing the characteristics of each structure, and even if the adapter 30 is added, the motor module cannot be enlarged.

In addition, since the flexible electric connection wire 12 is fixed on the base 40, the flexible electric connection wire 12 can be limited to move randomly by using the base 40, which is beneficial to protecting the welding position of the flexible electric connection wire 12 and the adapter 30 and reducing the stress of the welding position.

Second portion 37 is located on the side of second side wall 463; the positioning hole 32 is provided at the first portion 36 and the positioning groove 31 is provided at the second portion 37, thus enabling the flexible electrical connection wire 12 led out from the second side wall 463 to extend directly to the positioning groove 31. Furthermore, the L-shaped adapter 30 can be arranged by fully utilizing the L-shaped space formed by the connecting portion 44 and the wire clamping protrusion 46 on the upper surface of the central portion 43, so that the structure is more compact.

If the first groove wall 311 is replaced by the arc surface, after the flexible electric connection wire 12 moves left and right by a certain distance, the flexible electric connection wire 12 can climb along the arc surface and move towards the notch direction, the supporting direction of the first groove wall 311 to the flexible electric connection wire 12 is not towards the notch, but is misplaced towards the notch direction, and at the moment, the flexible electric connection wire 12 easily slides on the arc surface, so that the welding seam is uneven.

Further, since the second groove wall 312 and the third groove wall 313 are concave arc-shaped, and are similar to the circumferential surface of the flexible electric connection wire 12, they are arranged in a profiling manner, and can be welded with the flexible electric connection wire 12, so as to better wrap the flexible electric connection wire 12. Optionally, the second slot wall 312 is smoothly connected to the side of the first portion 36.

If the lead wire 111 of the stator coil 11 is directly welded to the conductive post 20, since the lead wire 111 of the stator coil 11 is made of a relatively hard material, it is difficult to bend and deform, and therefore, it is difficult for the lead wire 111 and the conductive post 20 to be in full contact with each other, and a gap occurs between them, which affects the welding effect of the lead wire 111 and the conductive post 20. Therefore, in this embodiment, the flexible electrical connection wire 12 is further added as a switching structure, one end of the flexible electrical connection wire 12 is electrically connected to the lead wire 111, and the other end of the flexible electrical connection wire 12 is soldered to the adaptor 30. Because the flexible electrical connection wire 12 is made of a softer material, the gap between the flexible electrical connection wire and the outgoing line 111 and the adaptor 30 can be compensated by deformation, so that better welding is realized. Furthermore, the flexible electrical connection wire 12 can be bent, so that it is easier to be inserted into the wire clamping hole 461.

The flexible electrical connection wire 12 refers to that the insulating sheath of the wire is made of soft rubber, so that the wire can be greatly deformed.

Alternatively, the stator coil 11 is formed by winding a flat wire, which refers to a wire having a non-circular cross section, for example, a flat wire having a square, rectangular, or elliptical cross section, or the like. When the stator coil 11 is formed by flat wire winding, the contact area between two adjacent turns of the coil is larger, the gap is smaller, the structure is more compact, and the stator coil 11 with the same volume can have more turns. The lead wires 111 of the stator coil 11 are also flat wires.

Further, the motor module further includes a conductive plate 92, and the outgoing line 111 and the flexible electrical connection line 12 may be soldered to the conductive plate 92, respectively, and the outgoing line 111 and the flexible electrical connection line 12 are electrically connected through the conductive plate 92.

Alternatively, the adapter 30 and the conductive plate 92 are made of conductive copper.

Further, the motor module further comprises a rotor 50, when the stator coil 11 is powered on, a magnetic field can be generated, the magnetic field acts on the rotor 50, so that the rotor 50 moves reciprocally, and the rotor 50 drives the cutter 60 connected with the rotor to move reciprocally, so that shearing force is generated, and shearing of hair is realized.

Further, the motor module further includes a mount 70, and the stator coil 11 is fixed to the mount 70, and the mount 70 is fixed to a housing 80 (fig. 12) of the motor module. The stator coil 11, the mover 50, the adaptor 30, the conductive posts 20, the base 40, and the like are mounted in the housing 80. The base 40 may be mounted to the mount 70 by an elastic member 91, such as a spring, the elastic member 91 providing cushioning to reduce transmission of vibrations from the mount 70 to the base 40. Of course, the base 40 may be directly fixed to the housing 80.

Specifically, the mounting seat 70 is located above the base 40, and the flexible electrical connection wire 12 and the adaptor 30 are located between the mounting seat 70 and the base 40, so that the space between the mounting seat 70 and the base 40 can be fully utilized, and the arch-shaped space of the base 40 is utilized for arrangement, so that the structure is compact. The lower surface of the mounting seat 70 is provided with two lugs 71, the two lugs 71 are distributed on two opposite sides of the flexible electrical connection wire 12 which are distributed in the horizontal direction, and the lugs 71 are connected with the adjacent connection parts 44 through an elastic piece 91. Therefore, when the mount 70 is shaken, the elastic member 91 may play a role of buffering, reducing or preventing shaking from being transferred to the base 40, thereby maintaining stability of the base 40 and preventing the base 40 from transferring vibration to other structures such as the housing 80.

Alternatively, the distance between the two connection portions 44 increases gradually from bottom to top, so that the space formed by the upper positions of the two connection portions 44 is larger, which facilitates the arrangement of the elastic member 91, the flexible electrical connection line 12, the adaptor 30, and the like, and makes the structure more compact.

The embodiment of the application also provides an electric shearing device, which can be specifically a shaver, a hair cutter, a hair trimmer and the like, and is not specifically limited herein. The electric shearing device includes a cutter 60 and a motor module, and the specific structure of the motor module is referred to the above embodiment and will not be described herein.

The cutter 60 may include a movable cutter and a stationary cutter, the stationary cutter is kept stationary with respect to the stator coil 11, the movable cutter is connected to the mover 50, and the movable cutter is reciprocally moved with respect to the stationary cutter by the mover 50, thereby generating a shearing force between the movable cutter and the stationary cutter. Of course, the cutter 60 may comprise two moving blades, the moving directions of which are opposite, and shearing may be achieved as well.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and are not limiting thereof; although the present application has been described in detail with reference to the foregoing embodiments, one of ordinary skill in the art will appreciate that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not drive the essence of the corresponding technical solutions to depart from the spirit and scope of the technical solutions of the embodiments of the present application.
