Description

[Technical field]

[0001] The utility model relates to an oscillating fan, in particular to an oscillating fan integrated control system based on a two-phase claw-pole stepping motor. [Background technology]

[0002] At present, the moving parts of the oscillating structure on the oscillating fan are generally driven by a five-wire four-phase claw-pole stepper motor. The five-wire four-phase claw-pole stepper motor is square wave driven. Since this driving method directly supplies the winding with a rectangular wave voltage according to the beat sequence, when the phase sequence is switched, the current obtained by the motor coil changes greatly, causing the magnetic rotor to receive a rotational torque from the air gap circumferential bypass claw pole and also change greatly, causing the entire stepper motor containing the gear reduction mechanism to produce a large noise due to vibration.

[0003] In addition, since there are certain errors in the manufacturing and assembly of the transmission components of the four-phase claw-pole stepper motor, when the gaps between the transmission parts caused by these errors are unbalanced, or when resonance occurs on the oscillating fan matched to the final application, vibration and noise are more obvious.

[0004] In addition, there are also errors in the processing and assembly of the oscillating head fan's oscillating head structural moving parts, which is one of the factors that cause noise during the movement of the oscillating head structural moving parts. This defect has always been a prominent customer complaint, and this problem has also been bothering engineers. Despite a lot of hardware structure optimization, it is still difficult to solve.

[0005] Furthermore, the control mainboard for connecting the oscillating motor in the existing oscillating fan includes a main control panel MCU and a Darlington tube. Since each oscillating structure moving part needs to be driven by a five-wire four-phase claw-pole stepper motor, and each five-wire four-phase claw-pole stepper motor needs to correspond to a Darlington tube, and the four pins of each Darlington tube are connected to the four pins corresponding to the main control panel MCU, when the oscillating fan is provided with N five-wire four-phase claw-pole stepper motors, the wiring connection between the main control panel MCU and all Darlington tubes is 4N. The use of this control scheme increases the circuit complexity on the control mainboard and also increases the manufacturing cost.

[0006] For a long time, in order to reduce or lower the noise or abnormal sound generated by the moving parts of the oscillating structure of the oscillating fan, such as left and right, up and down, the engineers of the oscillating fan manufacturing companies generally solve the problem by improving the moving parts of the oscillating structure being driven, including the connection structure, shape, connection matching and materials of the moving parts of the oscillating structure. Specifically, there are methods such as adding soft spacers or changing the flexibility and material of the fixed support of the motor, but none of them can significantly eliminate the vibration noise caused by the rotation of the oscillating fan body, and the frequency domain of this noise is between hundreds to thousands of hertz, which is sensitive to human ears. Especially in a quiet bedroom, the bad noise shows up, which makes the end user feel bad.

[0007] Therefore, the present invention is proposed just to solve the above-mentioned technical problems. [Utility Model Content]

[0052] The following is combined with Figure 1-20 The utility model is further described as follows:

[0053] The utility model is based on an integrated control system for an oscillating fan using a two-phase claw-pole stepper motor, comprising an oscillating fan main control panel 1 with a main control module 12 arranged in the oscillating fan, a main fan blade motor body 4, a two-phase claw-pole stepper motor body 2, and also comprising a main fan blade motor control module 41 and an oscillating motor control module 3, wherein the main control module 12 is provided with a main control panel MCU120, the oscillating fan main control panel 1 is provided with a connecting terminal 11, the two-phase claw-pole stepper motor body 2 is electrically connected to the oscillating fan main control panel 1 through the connecting terminal 11; the main control module 12 is electrically connected to the oscillating motor control module 3; the oscillating motor control module 3 is configured to be used for subdividing the modulated sine wave current output to drive the two-phase claw-pole stepper motor. The motor body 2 is working, and the shaking head motor control module 3 has a motor logic operation drive unit 31, a pre-drive unit 32 and a full-bridge drive unit 33. The motor logic operation drive unit 31 is used to complete the pulse micro-segmentation algorithm and the orthogonal SPWM wave pulse generation of the two channels, the pre-drive unit 32 is used to complete the TTL level conversion into a level that can drive the gate of the MOS tube, and the full-bridge drive unit 33 is used to convert the pulse signal into power output; the output end of the two-phase claw-pole stepper motor body 2 is directly or indirectly connected to the shaking head structure moving part of the shaking head fan to drive the shaking head structure moving part to drive the shaking head fan blades to shake accordingly, as shown in Table 1 below. The two-phase claw-pole stepper motor 2-2 phase excitation sequence adopted in the utility model is as follows.

[0054]

[0055] Table 1

[0056] like Fig.15As shown, the shaking head motor control module subdivides and modulates the two orthogonal sine wave current outputs. Therefore, when the two-phase claw-pole stepper motor body is driven by this current to work, the rotor of the two-phase claw-pole stepper motor achieves smooth rotation during the excitation rotation process, and the output torque changes smoothly. Therefore, the two-phase claw-pole stepper motor itself and the shaking head structure moving parts driven by it have the characteristics of smooth and silent operation.

[0057] In addition, the two orthogonal sine wave currents obtained after modulation are input to the two-phase claw-pole stepper motor, which effectively passivates the jitter of the rotor driven by rotation in the two-phase claw-pole stepper motor body, makes the rotor of the two-phase claw-pole stepper motor start and stop smoothly, and improves the service life of the gear transmission components on the two-phase claw-pole stepper motor.

[0058] The main fan motor body 4 is electrically connected to the main fan motor control module 41 to drive the oscillating fan blades to rotate. Figure 1-8 As shown, the main fan blade motor control module 41 is disposed on a main fan blade motor control circuit board 40 electrically connected to the oscillating fan main control panel 1; Figure 9-13 As shown, the main fan blade motor control module 41 is integrated on the oscillating fan main control panel 1. In this solution, the oscillating fan main control panel 1 is generally set on the head of the oscillating fan, and the corresponding operation control panel is also set on its head.

[0059] The oscillating fan integrated control system includes multiple two-phase claw-pole stepper motor bodies 2, generally two of which are used to control left and right oscillation and the other to control up and down oscillation. The output end of each of the two-phase claw-pole stepper motor bodies 2 is correspondingly connected to the oscillating structure moving parts of the oscillating fan. Each of the two-phase claw-pole stepper motor bodies 2 is correspondingly electrically connected to an oscillating motor control module 3. The oscillating fan main control panel 1 is provided with connection terminals 11 matching the number of the two-phase claw-pole stepper motor bodies 2.

[0060] like Fig.10 and Fig.12 As shown, each of the oscillating motor control modules 3 is integrated into a motor driver chip 30 and is arranged on the oscillating fan main control panel 1, each of the motor driver chip 30 is electrically connected to the corresponding signal end of the main control panel MCU120 on the main control module 12, and each of the motor driver chip 30 is electrically connected to the coil winding input end of the two-phase claw-pole stepper motor body 2 through the connection terminal 11 of the 4-pin structure.

[0061] like Figure 3 and Fig.11As shown, a plurality of the shaking head motor control modules 3 are packaged and integrated into a motor driving chip 30 and are arranged on the shaking head fan main control panel 1. Correspondingly, the motor driving chip 30 is configured to have a signal input terminal that matches the number of the two-phase claw-pole stepper motor bodies 2 and is used to directly or indirectly electrically connect to the corresponding signal terminal of the main control panel MCU120 on the main control module 12. By adopting this scheme, the circuit layout on the shaking head fan main control panel 1 appears to be simpler. Similarly, the motor driving chip 30 is electrically connected to the coil winding input terminal of each two-phase claw-pole stepper motor body 2 through the connection terminal 11 of the 4-pin structure.

[0062] like Figure 4 , 6 As shown in FIGS. 12 and 13 , the motor logic operation drive unit 31 is integrated on the main control panel MCU120 of the main control module 12 , and correspondingly, the pre-drive unit 32 and the full-bridge drive unit 33 are arranged on the oscillating fan main control panel 1 or on the two-phase claw-pole stepper motor body 2 .

[0063] like Figure 5 , 7 As shown, the motor logic operation drive unit 31 and the pre-drive unit 32 are integrated on the main control panel MCU120 of the main control module 12, and correspondingly, the full-bridge drive unit 33 is arranged on the oscillating fan main control panel 1 or on the two-phase claw-pole stepper motor body 2.

[0064] like Figure 7 , 8 As shown, the motor logic operation drive unit 31, the pre-drive unit 32 and the full-bridge drive unit 33 are all integrated on the main control panel MCU120 of the main control module 12. In comparison, with this solution, the circuit layout on the oscillating fan main control panel 1 is more concise, and the coil winding input end of each two-phase claw-pole stepper motor body 2 is electrically connected to the oscillating fan main control panel 1 through the connection terminal 11 of the 4-pin structure.

[0065] As a preferred embodiment of the present invention, Figure 1 , 9 As shown, the shaking head motor control module 3 is packaged and integrated into a motor driver chip 30 and is arranged on the two-phase claw-pole stepper motor body 2. The motor driver chip 30 is electrically connected to the main control panel MCU120 through the 3-pin structure connection terminal 11 on the shaking head fan main control panel 1. Only a power line and a signal line are required to connect the motor driver chip and the main control panel MCU, which simplifies the connection wiring between the main control panel MCU and the shaking head motor control module, that is, the connection lines between each two-phase claw-pole stepper motor and the shaking head fan main control panel are simplified from the original five lines to three lines, making the wiring simpler, optimizing the production process, and effectively reducing the overall production cost.

[0066] like Figure 6 As shown, the motor logic operation drive unit 31 is integrated on the main control panel MCU120, and the pre-drive unit 32 and the full-bridge drive unit 33 are packaged and integrated into a motor drive chip 30 and arranged on the two-phase claw-pole stepper motor body 2;

Although this solution can achieve a silent effect, since the pre-drive unit 32 is an 8-wire output and is electrically connected to the full-bridge drive unit on the two-phase claw-pole stepper motor body through an 8-pin structure connection terminal, the complexity of wiring on the oscillating fan main control panel is increased, thereby increasing the cost.

[0068] like Figure 16-19 As shown, the two-phase claw-pole stepper motor 2 includes a motor housing 21, a stator assembly 23 with two coil windings arranged in the motor housing 21, and a rotor assembly 24. The stator assembly 23 is provided with four pins 231 electrically connected to the coil winding wire ends, and the four pins 231 are electrically connected to the four output ends of the full-bridge drive unit 33. With the two-phase claw-pole stepper motor body structure, one of the two pins on the lower coil frame or the upper coil frame is the winding starting point, and the other is the winding end point, and the winding is distributed in the two coil frames, with a total of two groups of coils, and the distance between the two pins becomes larger, which reduces the difficulty of winding, optimizes the production process, improves the production efficiency and yield rate, and further reduces the cost.
