Description

Technical Field

[0001] This utility model relates to the field of mechanical drive technology, specifically to a magnetic suction structure with a single motor driving dual mechanisms. Background Technology

[0002] Traditional louver drive systems generally adopt a "single motor-single set drive" architecture, meaning that a single motor can only drive a single set of blades to achieve synchronous operation. This design played an important role in early home appliances. Its technical essence is to directly transmit rotational power to the louver blades through a rigid connection between the motor shaft and the transmission mechanism, thereby achieving synchronous start and stop control on a single plane.

[0003] However, this architecture has inherent limitations: in terms of functional scalability, traditional architectures cannot achieve differentiated motion control of multiple louvers using a single motor. When driving two different planes, independent motors and control systems must be configured, leading to a geometric increase in mechanical complexity. More seriously, in scenarios requiring coordinated continuous and intermittent operation, traditional solutions become completely technically unfeasible—there is a fundamental conflict in power distribution between continuous rotation and positioning control on different planes. At the system integration level, system redundancy is prominent. The dual-motor configuration necessitates dual configurations of the transmission mechanism, control system, and power management module, increasing equipment size, raising BOM costs, and causing multi-actuator coordination errors to accumulate over time, significantly reducing system reliability. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic suction structure with a single motor driving dual mechanisms, which solves the technical problem that traditional architectures cannot achieve differentiated motion control of multiple louvers with a single motor, especially in scenarios where continuous and intermittent operation need to be coordinated.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0007] The drive motor is directly connected to the continuous mechanism;

[0008] The intermittent mechanism is rotatably mounted on the continuous mechanism, and the continuous mechanism indirectly drives the intermittent mechanism through magnetic attraction;

[0010] The deflection limiting seat one, the deflection limiting seat two, and the drive motor are all fixedly connected to the housing of a household appliance using a magnetic suction structure with a single motor driving dual mechanisms.

[0011] As a further embodiment of this utility model: the continuous mechanism includes a rotating shaft, one end of which is connected to the output shaft of a drive motor, and the other end of which is connected to a swing blade. A magnetic chuck is fixedly sleeved on the rotating shaft, and a magnetic suction element is provided on the magnetic chuck.

[0012] As a further embodiment of this invention, the magnetic attractant is a driving magnet.

[0013] As a further embodiment of this utility model: the magnetic attraction component consists of a driving magnet and an auxiliary magnet.

[0014] As a further embodiment of this utility model: multiple auxiliary magnets are provided, and the multiple auxiliary magnets are located on both sides of the driving magnet and distributed around the circumference of the magnetic chuck;

[0015] The auxiliary magnet has a radial N / S pole distribution, and the magnetic pole distribution of the auxiliary magnet is consistent with that of the driving magnet.

[0016] As a further embodiment of this utility model: the driving magnet is fan-shaped, and the fan-shaped driving magnet is concentric with the magnetic chuck.

[0017] The fan-shaped deflection angle of the driving magnet is 45°-60°, and the driving magnet adopts a radial N / S pole distribution.

[0018] As a further embodiment of this utility model: the intermittent mechanism includes a rotating bearing sleeved on the rotating shaft, a swing plate connected to the rotating bearing, a second magnetic chuck in the swing plate, a through hole in the middle of the second magnetic chuck, and the first magnetic chuck located in the through hole;

[0019] The magnetic chuck two is equipped with a driven magnet;

[0020] The magnetic chuck one and the magnetic chuck two are spaced apart.

[0021] As a further embodiment of this utility model: the driven magnet is fan-shaped, and the fan-shaped driven magnet is concentric with the second magnetic chuck;

[0022] The sector deflection angle of the driven magnet is greater than that of the driving magnet, but less than 135°.

[0023] The driven magnet and the driving magnet have N / S poles distributed in the same direction;

[0024] When the driving magnet and the driven magnet are fully coupled, the magnetic force is greater than the maximum static friction between the swing plate and the first and second deflection limit seats.

[0025] As a further embodiment of this utility model: both ends of the swing plate are provided with extension bosses, and the two sets of extension bosses extend into the first deflection limiting seat and the second deflection limiting seat respectively.

[0028] The beneficial effects of this utility model are:

[0029] This invention utilizes a magnetic structure to enable a single motor to achieve differentiated motion control of continuous and intermittent mechanisms on two different planes. Specifically, the continuous mechanism is driven by a drive motor to achieve continuous motion, thereby realizing continuous control of the louvers on one plane. During the continuous motion, in conjunction with the magnetic attraction, the intermittent mechanism is driven to overcome the maximum static friction with deflection limit seats one and two to achieve deflection, thus realizing intermittent control of the louvers on the other plane.

[0030] This utility model adopts a magnetic non-contact structure design, which prevents wear during the movement process, ensures high durability and reliability of the parts, and the magnetic structure of this utility model is simple, small in size, low in noise, and highly versatile.

[0031] This invention incorporates multiple sets of auxiliary magnets, ensuring the intermittent mechanism remains stationary after the driving and driven magnets separate. The weak attraction between the auxiliary and driven magnets generates a holding torque, resisting external vibrations, wind resistance, or minor external forces, preventing accidental displacement of the swing plate. Furthermore, at the moment of forced separation of the driving and driven magnets, the weak coupling of the auxiliary magnets absorbs some magnetic energy, reducing mechanical impact and noise, and preventing mechanism vibration caused by hard separation. During the reverse reset process, the auxiliary magnets also help ensure a smoother transition when the driving and driven magnets realign, reducing the "impact effect." Additionally, the weak coupling of the auxiliary magnets provides a small amount of reset torque during the reverse reset process (when the driving and driven magnets are initially misaligned), helping to counteract the gravitational torque generated by the swing plate's tilt.

Detailed Implementation

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0045] like Figures 1-9 As shown, this utility model provides a magnetically attached structure for a single motor driving two mechanisms. This magnetic structure enables a single motor to achieve differentiated motion control of a continuous mechanism 200 and an intermittent mechanism 300 on two different planes. Furthermore, the non-contact magnetic design prevents wear during motion, resulting in high component durability and reliability. The magnetically attached structure is also simple in design, small in size, low in noise, and highly versatile.

[0046] like Figure 1 As shown, the magnetic suction structure of the present invention, which is driven by a single motor and has two mechanisms, includes a drive motor 100, a continuous mechanism 200, an intermittent mechanism 300, a deflection limit seat 500 and a deflection limit seat 600.

[0047] The drive motor 100 is directly connected to the continuous mechanism 200, while the intermittent mechanism 300 is rotatably mounted on the continuous mechanism 200, and the intermittent mechanism 300 and the continuous mechanism 200 are indirectly driven by magnetic attraction.

[0048] Furthermore, deflection limit seat 1 500 and deflection limit seat 2 600 are respectively provided at both ends of the intermittent mechanism 300, and the two ends of the intermittent mechanism 300 are slidably engaged with deflection limit seat 1 500 and deflection limit seat 2 600, wherein deflection limit seat 1 500 and deflection limit seat 2 600 are fixed on the housing of a household appliance using the magnetic suction structure of a single motor driven dual mechanism of this utility model.

[0049] It should be noted that the aforementioned household appliances are existing technologies, and their specific structures will not be elaborated here. The connection relationships of this utility model will be further illustrated below using an air conditioner that requires louvered drive as an example.

[0050] The deflection limiting seat 500 and the deflection limiting seat 600 of this utility model are fixed inside the outer casing at the air conditioner outlet, and the aforementioned drive motor 100 is also fixed to the air conditioner outer casing (e.g., Figure 10 (As shown). The specific positions and angles of the deflection limit seat 1 500 and the deflection limit seat 2 600 are designed and installed according to the actual louver control requirements.

[0051] In use, the drive motor 100 drives the continuous mechanism 200 to move continuously, thereby achieving continuous control of the louvers on one plane. During the continuous movement, in conjunction with magnetic attraction, the intermittent mechanism 300 is driven to overcome the maximum static friction with the deflection limit seat 500 and the deflection limit seat 600 to achieve deflection, thereby achieving intermittent control of the louvers on another plane.

[0052] Furthermore, such as Figure 3 and Figure 4As shown, the continuous mechanism 200 of this utility model includes a rotating shaft 201. One end of the rotating shaft 201 is connected to the output shaft of the drive motor 100, and the other end is connected to a swing blade 202. A magnetic chuck 203 is also fixedly sleeved on the rotating shaft 201, and a magnetic suction element is provided on the magnetic chuck 203.

[0053] The magnetic chuck is a driving magnet 204, which is fan-shaped and concentric with the magnetic chuck 203. The fan-shaped deflection angle (i.e., coverage angle) is 45°-60°. The driving magnet 204 has a radial N / S pole distribution (the fan-shaped magnet is magnetized along the radial direction, i.e., the N pole points to the center and the S pole points to the outer edge (or vice versa)). Furthermore, the driving magnet 204 can be a neodymium iron boron magnet, such as a neodymium iron boron N52 grade magnet.

[0054] Furthermore, such as Figure 3 and Figure 4 As shown, the intermittent mechanism 300 of this utility model includes a rotary bearing 303 sleeved on a rotating shaft 201. A swing plate 301 is connected to the rotary bearing 303. The swing plate 301 has a mounting groove on one side corresponding to the magnetic chuck 203. A magnetic chuck 302 is installed in the mounting groove, and a through hole is opened in the middle of the magnetic chuck 302. The magnetic chuck 203 is located in the through hole. Furthermore, it should be noted that in order to ensure the stable deflection of the intermittent mechanism 300 (to avoid the uneven friction between the swing plate 301 and the deflection limit seat 500 and the deflection limit seat 600 affecting the deflection stability), the swing plate 301 is rotatably connected to the rotating shaft 201 through the rotary bearing 303. Although there is some rolling friction with the continuous mechanism 200, the influence can be further eliminated by applying lubricating oil. At the same time, the power loss due to this friction is compensated by increasing the driving force later. It should be further explained that, in order to make the power transmission more stable, the output shaft of the drive motor 100, the rotating shaft 201, the magnetic chuck 1 203 and the magnetic chuck 2 302 in this utility model are coaxially arranged. The coaxial arrangement makes the power transmission more stable and avoids transmission blockage and fluctuation.

[0055] Furthermore, the magnetic chuck 1 203 and magnetic chuck 2 302 are spaced apart, meaning that a set gap is maintained between magnetic chuck 1 203 and magnetic chuck 2 302 to prevent them from contacting each other, thus avoiding friction that could affect the power transmission of the intermittent mechanism 300.

[0056] Furthermore, the magnetic chuck 302 includes a driven magnet 304 arranged in a fan shape. This driven magnet 304 is concentric with the magnetic chuck 302, and its fan-shaped deflection angle is greater than that of the driving magnet 204 but less than 135°. The driven magnet 304 and the driving magnet 204 have their N / S poles distributed in the same direction (polarity mirror symmetry), meaning that if the N pole of the driving magnet 204 points to the center, then the N pole of the driven magnet 304 also points to the center. The driven magnet 304 can also be a neodymium iron boron magnet, such as a N52 grade neodymium iron boron magnet.

[0057] Furthermore, the distance between the driven magnet 304 and the driving magnet 204 is 1–3 mm, which ensures sufficient driving force when coupling and does not result in excessive resistance when separating.

[0058] Furthermore, when the swing plate 301 is set vertically, the center of gravity is balanced about the axis of rotation 201 (a driven magnet 304 is provided on one side of the magnetic chuck 302, and the center of gravity is offset in the normal state. In this utility model, the swing plate 301 is compensated to balance the center of gravity. The compensation method is existing technology, such as slotting the swing plate 301 on the opposite side of the driven magnet 304 to counterweight, etc., which will not be described in detail here).

[0059] Among them, such as Figure 4 As shown, the magnetic chuck 302 of this utility model can be provided with carding platforms on both sides and carding slots at the corresponding positions of the mounting slots, which facilitates the snap-fit ​​and alignment of the magnetic chuck 302, reduces the calibration time during installation, and makes the synchronous movement of the magnetic chuck 302 and the swing plate 301 more stable.

[0060] Furthermore, such as Figures 1-4 As shown, in this utility model, the swing plate 301 is provided with extension bosses 3010 at both ends of the deflection limiting seat 500 and the deflection limiting seat 600. The two sets of extension bosses 3010 extend into the mating grooves opened in the middle of the deflection limiting seat 500 and the deflection limiting seat 600, respectively. A sliding rod 3011 can be detachably connected to the side of each set of extension bosses 3010 near the drive motor 100. The corresponding deflection limiting seat 500... A first slide groove 501 is provided, and a second slide groove 601 is provided in the second deflection limit seat 600. The corresponding sliding rods 3011 on both sides cooperate with the first slide groove 501 and the second slide groove 601 respectively. The first slide groove 501 and the second slide groove 601 are located on both sides of the vertical center line of the swing plate 301. The first slide groove 501 and the second slide groove 601 are both arc-shaped, and the center of the first slide groove 501 and the second slide groove 601 are both located on the axial direction of the rotation shaft 201.

[0061] When the swing plate 301 deflects, the sliding rod 3011 slides in the corresponding groove 501 or groove 601 in the direction of deflection. It should be further noted that the sliding rod 3011, the deflection limit seat 500, and the deflection limit seat 600 are all made of nylon 66. The sliding rod 3011 is in full contact with both grooves 501 and 601, providing frictional resistance and ensuring that the swing plate 301 remains stationary when the intermittent mechanism 300 is not moving. Furthermore, to improve the structural service life, a wear-resistant coating, such as a PTFE composite coating (17% silicon carbide whiskers added to PTFE), is applied to grooves 501 and 601. The sliding rod 3011 is also easily replaceable.

[0062] Furthermore, such as Figures 2-4 As shown, a limiting post 101 is provided on one side of the bottom of the drive motor 100 of this utility model, and a limiting arc groove 305 is opened at the corresponding position of the swing plate 301. The center of the limiting arc groove 305 is located on the axis of the rotating shaft 201, and the limiting post 101 extends into the limiting arc groove 305 for limiting the deflection of the intermittent mechanism 300. The specific deflection angle can be designed according to actual needs.

[0063] When this utility model is driven, the drive motor 100 is started to drive the rotating shaft 201 to rotate, the rotating shaft 201 drives the swing blade 202 to rotate continuously, and the rotating shaft 201 synchronously drives the magnetic chuck 203 to rotate. The drive magnet 204 in the magnetic chuck 203 deflects. When the drive magnet 204 is completely aligned with the driven magnet 304 in the magnetic chuck 202, the coupling force reaches its peak, overcoming the maximum static friction between the swing blade 301 and the deflection limit seat 500 and the deflection limit seat 600. The drive magnet 204 then drives the driven magnet 304. 4. Rotation causes the driven magnet 304 to deflect the magnetic chuck 302, which in turn causes the swing plate 301 to deflect. When the swing plate 301 deflects to the set position, it stops by the cooperation of the limiting post 101 and the limiting arc groove 305. Meanwhile, the rotating shaft 201 drives the swing blade 202 to continue rotating. Then, under the drive of the drive motor 100, the drive magnet 204 and the driven magnet 304 are forcibly separated. After separation, the swing plate 301 continues to move to the set position. Then, the drive motor 100 reverses and repeats the above process to reset the swing blade 202 and the swing plate 301.

[0064] It should be noted that the deflection angle range of the driving magnet 204 in this invention is 0°-360°.

[0065] It should be noted that when the driving magnet 204 and the driven magnet 304 are fully coupled, the magnetic force design is greater than the maximum static friction between the swing plate 301 and the deflection limit seat 500 and the deflection limit seat 600. The above magnetic force design value can be obtained from the maximum static friction test in actual installation, and can be flexibly adjusted by magnetization according to actual needs.

[0066] It should be noted that this invention is applicable to scenarios with moderate load (e.g., torque < 5 N·m) and low speed (< 100 RPM).

[0067] This invention enables continuous movement of a swaying blade 202 (louver) on one plane and intermittent movement of a swaying plate 301 (louver) on another plane using a single drive motor 100. This eliminates the need for multiple sets of motors, solves the problem of system redundancy at the system integration level, reduces equipment size, and lowers costs.

[0068] In another embodiment of this utility model, the magnetic attraction component consists of a driving magnet 204 and auxiliary magnets 205. Multiple auxiliary magnets 205 are provided, distributed around the center circumference of the magnetic chuck 203 on both sides of the driving magnet 204. Adjacent auxiliary magnets 205 are distributed at the same angle, and the interval between adjacent auxiliary magnets 205 is 30°-45°. The auxiliary magnets 205 also adopt a radial N / S pole distribution consistent with the driving magnet 204. The auxiliary magnets 205 are made of ferrite or low-grade neodymium iron boron magnets, and the surface magnetic intensity of the auxiliary magnets 205 is much lower than that of the driven magnet 304 and the driving magnet 204.

[0069] When multiple sets of auxiliary magnets 205 are simultaneously coupled to the driven magnet 304, the magnetic force design is less than the maximum static friction between the swing plate 301 and the deflection limit seat 1 500 and the deflection limit seat 2 600. The magnetic force design value can be obtained based on actual installation tests.

[0070] The instruction manual states that, in order to reduce the number of tests, it can be assumed that all auxiliary magnets 205 are uniformly coupled to the driven magnets 304, and the surface magnetic intensity of a single auxiliary magnet 205 can be calculated.

[0071] This invention, by adding multiple sets of auxiliary magnets 205, ensures that the intermittent mechanism 300 remains stationary after the drive magnet 204 and driven magnet 304 separate. The weak attraction between the auxiliary magnets 205 and driven magnet 304 generates a holding torque, resisting external vibrations, wind resistance, or slight external forces, and preventing accidental displacement of the swing plate 301. Furthermore, at the moment of forced separation of the drive magnet 204 and driven magnet 304, the weak coupling of the auxiliary magnets 205 absorbs some magnetic energy, reducing mechanical impact and noise, and preventing mechanism vibration caused by hard separation. During the reverse reset process, the auxiliary magnets 205 also help the drive magnet 204 and driven magnet 304 to realign more smoothly, reducing the "impact effect." Moreover, the weak coupling traction of the auxiliary magnets 205 can provide a small amount of reset torque during the reverse reset process (when the drive magnet 204 and driven magnet 304 are not initially aligned), helping to counteract the gravitational torque generated by the tilt of the swing plate 301.

[0072] Specifically, such as Figures 4-8 The diagram illustrates the driving state changes of this invention when the magnetic attractor consists of a driving magnet 204 and an auxiliary magnet 205. It is important to note that because the magnetic torque has a non-linear relationship with the alignment angle (approximately a sine function), the torque drops sharply when not fully aligned. Therefore, even when the driving magnet 204 and the driven magnet 304 are not aligned, and some of the auxiliary magnets 205 correspond to the driven magnet 304, the provided torque supplement cannot meet the driving conditions.

[0073] Furthermore, the weak coupling force provided by some of the auxiliary magnets 205 and the driven magnet 304 can be used as an error range to make reasonable adjustments when designing the magnetic force of the driving magnet 204 and the driven magnet 304.

[0074] Furthermore, in the actual driving process, there is a slight error in the timing of the driving magnet 204 driving the driven magnet 304, but this does not affect the actual louver driving process.

[0075] In another embodiment of this utility model, such as Figure 9 As shown, multiple sets of continuous components are added. Each continuous component consists of a rotating shaft 201, a swing blade 202, a rotating bearing 303, and a transmission gear 400. A transmission gear 400 is also provided on the rotating shaft 201 corresponding to the drive motor 100. The multiple sets of transmission gears 400 are connected by a synchronous belt to achieve synchronous drive.

[0076] In this embodiment, when driven, the drive motor 100 can synchronously drive multiple sets of swing blades 202 to swing continuously.

[0077] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0078] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0079] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
