Description

Technical Field

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

[0002] Fans are common household appliances, and the motor is one of the main components inside a fan. In manufacturing, some motors connect their leads to an external source (e.g., a power source) via wires. During fan assembly, workers typically need to use screws to secure the wires and ensure continuity. This design requires workers to spend additional time connecting the wires, impacting assembly efficiency.

[0003] For example, Chinese patent application number CN201920529530 discloses a fan motor, which specifically describes "the motor being electrically connected to an external power source via a connecting wire, then rotating the upper locking block to align it with the lower locking block, and then inserting the protrusion at the bottom of the upper locking block into the slot to fix the connecting wire." The connecting wire is fixed to the external power source with screws. This design requires workers to spend considerable time connecting the wires, affecting assembly efficiency.

[0004] For example, CN202323009043.X discloses an air-conditioning fan that facilitates the concealment of connecting wires. Specifically, it discloses that "the battery compartment is provided with a battery and a control panel electrically connected to the battery, and the control panel is connected to the motor through a connecting wire." This design requires workers to spend more time connecting the wires, which affects assembly efficiency. Utility Model Content

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a oscillating motor.

[0031] The oscillating motor is equipped with a connector 30. After the stator winding 21 is wound, the pins of the stator winding 21 are soldered together with the first connection terminal 323 of the connector 30. The interface 311 of the connector 30 is exposed on the outside of the motor housing 11, which makes it convenient for workers to assemble by plugging in the connector 30, which helps to improve assembly efficiency and reduce assembly costs.

[0032] This application provides a oscillating motor, including a motor body 10, which includes a motor housing 11, a stator 20, and a rotor 30. The stator 20 and rotor 30 are disposed within the motor housing 11, with the rotor 30 passing through the stator 20. The stator 20 includes a frame 210 and a stator winding 21 wound around the frame 210. A first connection terminal 323 of a connector 30 is connected to the pins of the stator winding 21, and the interface 311 of the connector 30 is exposed outside the motor housing 11. The output shaft 31 of the rotor 30 passes through a oscillating mechanism 40, and the output shaft 31 drives the drive rod 45 of the oscillating mechanism 40 to rotate. The stator 20 is the fixed part of the motor, typically composed of an iron core and windings. The stator winding 21 generates a magnetic field through current, which interacts with the magnetic field of the rotor 30, thereby generating an electromagnetic force. The rotor 30 is the rotating part of the motor, typically composed of an iron core and windings. The rotor 30 winding generates a magnetic field through current, which interacts with the stator 20 magnetic field to produce torque, thus realizing energy conversion and transfer. The frame 210 is prefabricated. The winding machine winds the stator winding 21 onto the frame 210. After the stator winding 21 is wound, the winding machine directly solders the pins of the stator winding 21 to the first connection terminal 323 of the connector 30. This design eliminates the need for manual wiring and soldering. The rotor 30 is powered via brushes and a commutator (rectifier). The brushes and commutator are also connected to the connector 30 via wires. Therefore, after the stator 20 and rotor 30 are assembled, both can draw power from the connector 30, making the assembly of this type of oscillating motor very convenient. Furthermore, this connector can not only supply power but also be used for signal monitoring. Therefore, signal transmission and power supply of this type of oscillating motor can be directly achieved through the connector 30, making fan assembly even simpler. During assembly, workers simply insert the corresponding connector into connector 30, eliminating the need for additional screws or soldered wiring, thus improving assembly efficiency and reducing costs. Connector 30 can be a motor connector 30 (e.g., Amass MT30, XT30U-F / M, AHUA M20); or a power connector 30 (e.g., Delixi Electric Aerospace Plug and Socket Connector 30, Huijun Copper Lug). The motor housing 11 can be a metal or plastic housing. The output shaft 31 of rotor 30 drives the drive rod 45 of oscillating mechanism 40 to rotate. Drive rod 45 is connected to a four-bar linkage, allowing the fan to oscillate left and right.

[0033] Preferably, the connector 30 includes a first connector housing 320, a second connector housing 310, a first connecting terminal 323, and a second connecting terminal 313; the first connecting terminal 323 and the second connecting terminal 313 are elastic; the first connecting terminal 323 is disposed in the first connector housing 320, and its end extends out of the first connector housing 320; the second connecting terminal 313 is disposed in the second connector housing 310, and its end is exposed at the interface 311. The first connector housing 320 and the second connector housing 310 are insulated. The first connecting terminal 323 and the second connecting terminal 313 are elastic conductive terminals. The first connecting terminal 323 and the second connecting terminal 313 can be connected by direct soldering or wire soldering. Before the skeleton 210 is wound, the first connecting terminal 323 is embedded in the first connector housing 320, and the second connecting terminal 313 is embedded in the second connector housing 310, and the first connecting terminal 323 and the second connecting terminal 313 are electrically connected together. After the first connecting terminal 323 and the second connecting terminal 313 are assembled on the connector 30, the winding machine winds the stator winding 21 onto the stator 20, and then the winding machine solders the pins to the first connecting terminal 323.

[0034] Preferably, the first connector housing 320 includes a first connector housing body 321 and a first connector housing cover 322, with the first connector housing cover 322 fastened to the first connector housing body 321. The end of the first connecting terminal 323 is connected to the pin of the stator winding 21 by welding or pressing. In this embodiment, the frame 210 is injection molded, and the first connecting terminal 323, the second connecting terminal 313, the first connector housing body 321, the second connector housing 310, and the frame 210 are injection molded together. This design structure has good strength, is easy to assemble, and does not require an additional wiring circuit board, thus saving costs. Of course, the first connector housing body 321, the second connector housing 310, and the frame 210 can also be assembled. The first connecting terminal 323 is embedded into the first connector housing body 321, and then the first connector housing cover 322 is placed on the first connector housing body 321, thus limiting the first connecting terminal 323 and preventing it from loosening. The first connector housing cover 322 and the first connector housing body 321 are assembled together by fastening, which is very convenient. The first connecting terminal 323 and the second connecting terminal 313 are preferably connected together by welding.

[0035] Preferably, the inner wall of the interface 311 of the second connector housing 310 is provided with a limiting strip 312, and the middle of the second connecting terminal 313 is provided with a limiting notch. The second connecting terminal 313 is inserted into the interface 311, and the limiting strip 312 is engaged in the limiting notch. The limiting strip 312 protrudes from the inner wall of the interface 311. The second connecting terminal 313 is bent and inserted into the interface 311, and the limiting strip 312 is engaged in the limiting notch of the second connecting terminal 313. This simple structure allows the second connecting terminal 313 to be assembled. During assembly, it is only necessary to press the second connecting terminal 313 into the interface 311, making assembly very efficient and convenient.

[0036] Preferably, the motor housing 11 includes a first motor housing 13 and a second motor housing 15. A first limiting plate 14 extends from the first motor housing 13, and a second limiting plate 16 extends from the second motor housing 15. The first limiting plate 14 and the second limiting plate 16 abut against the outer periphery of the frame 210. A first connecting member 18 fastens the first motor housing 13, the frame 210, and the second motor housing 15 together. The first connecting member 18 is a screw or bolt. When assembling this oscillating motor, the first motor housing 13 and the second motor housing 15 clamp the frame 210, and the first limiting plate 14 and the second limiting plate 16 abut against the outer periphery of the frame 210. This structure facilitates positioning during installation and also enhances the firmness and compactness of the assembled first motor housing 13, the second motor housing 15, and the frame 210.

[0037] Preferably, the second motor housing 15 is provided with a positioning port 17, and the connector 30 is embedded in the positioning port 17. Part of the structure of the connector 30 is integrally formed with the frame 210. During assembly, the connector 30 is embedded in the positioning port 17. This design facilitates the installation and positioning of the connector 30, and also improves the assembly firmness of the connector 30 and the strength of the structure, which can prevent the connector 30 from being damaged.

[0038] Preferably, the skeleton 210 includes a first skeleton 211, a second skeleton 212, a third skeleton 214, and a skeleton frame 215. The first skeleton 211 and the third skeleton 214 are disposed on the second skeleton 212. The inner wall of the skeleton frame 215 is provided with a limiting groove 216, and the second skeleton 212 is provided with a limiting block 213, which is embedded in the limiting groove 216. The first skeleton 211 and the third skeleton 214 form a winding post, and the end of the winding post has a third limiting plate 217 that overlaps vertically. The limiting block 213 protrudes from the winding post. The third limiting plate 217 facilitates alignment and installation. During assembly of the skeleton 210, the first skeleton 211 and the third skeleton 214 are closed on the second skeleton 212. The limiting block 213 set on the second skeleton 212 passes through the winding post. The winding machine winds the stator winding 21 around the winding post. After the wire is completed, the limiting groove 216 set on the inner wall of the skeleton frame 215 is embedded into the limiting groove 216. In this way, the first skeleton 211, the second skeleton 212, the third skeleton 214, and the skeleton frame 215 can be firmly assembled together. This assembly structure is simple and efficient, and the cooperation between them does not require other accessories.

[0039] Preferably, ventilation holes 12 are provided on the first motor housing 13 and the second motor housing 15, through which air passes through the motor body 10. The ventilation holes 12 can be used for ventilation; when the fan is working, air can flow through the ventilation holes 12. This design helps to cool the inside of the motor and ensures normal operation of the motor.

[0040] Preferably, the oscillating mechanism 40 includes a protective shell 41, and a first gear 42, a second gear 43, and a third gear 44 disposed within the protective shell 41. A fourth gear 32 is disposed on the output shaft 31 of the rotor 30. The first gear 42 and the second gear 43 can be separately disposed together. The fourth gear 32 meshes with the first gear 42, and the second gear 43 meshes with the third gear 44. A drive rod 45 is disposed on the third gear 44. The power of the fourth gear 32 is transmitted to the first gear 42, the second gear 43, and the third gear 44. The third gear 44 drives the drive rod 45 to rotate, and the drive rod 45 drives the four-bar linkage, which in turn drives the motor to oscillate. Alternatively, the fourth gear 32 can be a worm gear, and the first gear 42 can be a worm wheel. A connecting shaft 46 passes through the first gear 42 and the second gear 43. A connecting pin or a steel ball is disposed on the connecting shaft 46. When the connecting shaft 46 is pressed, the connecting pin or the steel ball is engaged in a slot within the first gear 42, thereby establishing a power connection between the first gear 42 and the second gear 43; otherwise, the connection is broken. The protective shell 41 is made of plastic.

[0041] Preferably, a gear position switch 47 and a starting capacitor 48 are fastened to the third gear 44. The gear position switch 47 is connected to the first connector 30, and the starting capacitor 48 is connected to the second connector 30. A fastening groove is formed on the protective housing 41, and the gear position switch 47 is fastened into the fastening groove. This design simplifies the assembly of the gear position switch 47, requiring no additional screws, and helps improve fan assembly efficiency. The starting capacitor 48 is connected to the second connector 30 via a wire. The starting capacitor 48 enables a smoother motor start-up.

[0042] In summary, the key design feature of this utility model is that after the stator winding 21 is wound, the winding machine welds the stator winding 21 to the first connection terminal 323 of the connector 30; the interface 311 of the connector 30 is exposed on the outside of the motor housing 11, which makes it convenient for workers to assemble by plugging in the connector 30, which helps to improve assembly efficiency and reduce assembly costs.
