Description

Technical Field

[0001] The present invention relates to the field of mechanical drive technology, and in particular to a magnetic attraction structure with a single motor driving two mechanisms. Background Art

[0002] Traditional blind drive systems generally utilize a "single motor, single drive" architecture, meaning a single motor drives only a single set of blades for synchronous operation. This design played a significant role in early home appliances. Essentially, the technology utilizes a rigid connection between the motor shaft and the transmission mechanism, directly transmitting rotational power to the blind blades, achieving synchronized start and stop control within a single plane.

[0003] However, this architecture has inherent limitations: in terms of functional scalability, the traditional architecture cannot achieve differentiated motion control of multiple groups of blinds through a single motor. When it is necessary to drive two different planes, independent motors and control systems must be configured, resulting in a geometric increase in the complexity of the mechanical structure. What is more serious is that in scenarios where continuous operation and intermittent operation need to be coordinated, the traditional solution completely loses its technical feasibility - there is a fundamental power distribution conflict in the continuous rotation and positioning control on different planes. At the system integration level, the problem of system redundancy is prominent. The dual-motor configuration requires dual configuration of the transmission mechanism, control system and power management module, which increases the size of the equipment and the BOM cost. In addition, the coordination errors of multiple actuators accumulate over time, and the reliability of the system is significantly reduced. Summary of the Invention

[0028] Beneficial effects of the present invention:

[0029] This invention uses a magnetic structure to enable a single motor to achieve differentiated motion control of continuous and intermittent mechanisms on two different planes. Specifically, the drive motor drives the continuous mechanism to continuously move, thereby achieving continuous control of the blinds on one plane. During this continuous motion, the intermittent mechanism, coupled with magnetic attraction, is driven to overcome the maximum static friction with the first and second deflection limiters to achieve deflection, thereby achieving intermittent control of the blinds on the other plane.

[0030] The present invention adopts a magnetic non-contact structural design, so that no wear is generated during the movement process, the parts are highly durable and reliable, and the magnetic structure of the present invention has a simple structure, small size, low noise and strong versatility.

[0031] The present invention adds multiple sets of auxiliary magnets so that the intermittent mechanism is in a stationary state after the driving magnet and the driven magnet are separated. The weak attraction between the auxiliary magnet and the driven magnet generates a holding torque to resist external vibration, wind resistance or slight external force, and prevent the swing plate from accidentally displacing. Moreover, at the moment when the driving magnet and the driven magnet are forcibly separated, the weak coupling of the auxiliary magnet can absorb part of the magnetic energy, reduce mechanical shock and noise, and avoid the mechanism shaking caused by hard separation. During the reversal and reset process, the auxiliary magnet can also help the driving magnet and the driven magnet to realign more smoothly when transitioning, reducing the "impact effect", and the weak coupling traction of the auxiliary magnet can provide a small amount of reset torque during the reversal and reset process (at the beginning when the driving magnet and the driven magnet are not aligned), to help offset the gravitational torque generated by the deflection of the swing plate.

DETAILED DESCRIPTION

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0045] like Figures 1-9As shown, the present invention provides a magnetic structure with a single motor driving two mechanisms. This 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 magnetic, contactless design eliminates wear during motion, resulting in high component durability and reliability. Furthermore, the magnetic structure of the present invention offers simplicity, compact size, low noise, and high versatility.

[0046] like Figure 1 As shown, a single-motor-driven dual-mechanism magnetic attraction structure of the present invention includes a driving motor 100, a continuous mechanism 200, an intermittent mechanism 300, a deflection limiting seat 1 500 and a deflection limiting seat 2 600;

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

[0048] Furthermore, a deflection limit seat 1 500 and a 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 respectively slidably matched with the deflection limit seat 1 500 and the deflection limit seat 2 600, wherein the deflection limit seat 1 500 and the deflection limit seat 2 600 are fixed on the shell of a household appliance with a magnetic structure of a single motor driven dual mechanism using the present invention.

[0049] It should be noted that the above household appliances are prior art and their specific structures are not described in detail here. The following takes an air conditioner that requires shutter drive as an example to further illustrate the connection relationship of the present invention. The deflection limit seat 1 500 and the deflection limit seat 2 600 of the present invention are fixed to the inner side of the outer shell at the air outlet of the air conditioner, and the above-mentioned drive motor 100 is also fixed to the outer shell of the air conditioner (such as Figure 10 The specific positions and angles at which the first deflection limit seat 500 and the second deflection limit seat 600 are fixed are designed and installed according to the actual louver control requirements.

[0050] When in use, the continuous mechanism 200 is driven by the driving motor 100 to move continuously, thereby realizing continuous control of the blinds on one plane. During the continuous movement, the intermittent mechanism 300 is driven by magnetic attraction to overcome the maximum static friction with the deflection limit seat 1 500 and the deflection limit seat 2 600 to realize deflection, thereby realizing intermittent control of the blinds on another plane.

[0051] Furthermore, if Figure 3 and Figure 4As shown, the continuous mechanism 200 in the present invention includes a rotating shaft 201, one end of which is connected to the output shaft of the driving motor 100, and the other end is connected to a swing leaf 202. A magnetic suction cup 203 is fixedly sleeved on the rotating shaft 201, and a magnetic suction part is provided on the magnetic suction cup 203.

[0052] The magnetic element is a driving magnet 204, which is fan-shaped and concentric with magnetic chuck 1 203. The fan-shaped driving magnet 204 has a fan-shaped deflection angle (i.e., coverage angle) of 45°-60°. The driving magnet 204 has a radial north-south pole distribution (the fan-shaped magnet is magnetized radially, with the north pole pointing toward the center and the south pole toward the outer edge (or vice versa)). Furthermore, the driving magnet 204 can be a strong neodymium iron boron magnet, such as N52 grade.

[0053] Furthermore, if Figure 3 and Figure 4 As shown, the intermittent mechanism 300 of the present invention includes a rotating bearing 303 mounted on the rotating shaft 201. A swing plate 301 is connected to the rotating bearing 303. A mounting slot is defined on one side of the swing plate 301 corresponding to the magnetic chuck 1 203. A magnetic chuck 2 302 is mounted in the mounting slot. A through hole is defined in the center of the magnetic chuck 2 302, and the magnetic chuck 1 203 is positioned within the through hole. It should be further explained that, to ensure stable deflection of the intermittent mechanism 300 (to prevent unbalanced friction between the swing plate 301 and the deflection limiter 1 500 and the deflection limiter 2 600 from affecting deflection stability), the swing plate 301 is rotationally connected to the rotating shaft 201 via the rotating bearing 303. Although some rolling friction with the continuous mechanism 200 exists, this effect can be further eliminated by applying lubricant. Furthermore, the power loss caused by this friction is compensated by subsequently increasing the driving force. It should be further explained that in order to make the power transmission more stable, the output shaft of the driving motor 100, the rotating shaft 201, the magnetic suction cup 1 203 and the magnetic suction cup 2 302 in the present invention are coaxially arranged. The coaxial arrangement makes the power transmission more stable and avoids transmission blockage and fluctuation.

[0054] Furthermore, a gap is set between the magnetic chuck 1 203 and the magnetic chuck 2 302 , that is, a set gap is maintained between the magnetic chuck 1 203 and the magnetic chuck 2 302 without contact, thereby avoiding friction that affects the power transmission of the intermittent mechanism 300 .

[0055] Furthermore, the second magnetic chuck 302 is provided with a driven magnet 304. The driven magnet 304 is arranged in a fan-shaped configuration. The fan-shaped driven magnet 304 is concentric with the second magnetic chuck 302, and the fan-shaped deflection angle is greater than the fan-shaped deflection angle of the driving magnet 204 and less than 135°. The driven magnet 304 and the driving magnet 204 have the same north / south pole distribution (polarity mirror symmetry), that is, if the north pole of the driving magnet 204 points to the center of the circle, then the north pole of the driven magnet 304 also points to the center of the circle. The driven magnet 304 can also be a strong neodymium iron boron magnet, such as N52 grade neodymium iron boron.

[0056] Furthermore, the distance between the driven magnet 304 and the driving magnet 204 is 1-3 mm, so that the driving force is sufficient when coupling and the resistance is not too large when separating.

[0057] Furthermore, when the swing plate 301 is set vertically, the center of gravity is balanced left and right about the axis of the rotating shaft 201 (a driven magnet 304 is set on one side of the magnetic suction cup 302, and the center of gravity is offset in the normal state. The swing plate 301 in the present invention is compensated to balance the center of gravity. The compensation means is the existing technology, such as slotting and counterweighting on the opposite side of the driven magnet 304 of the swing plate 301, which will not be elaborated here).

[0058] Among them Figure 4 As shown, clamping platforms can be set on both sides of the magnetic suction cup 2 302 of the present invention, and clamping slots are set at positions corresponding to the installation slots to facilitate the clamping and alignment of the magnetic suction cup 2 302, reduce the calibration time of installation, and make the synchronous movement of the magnetic suction cup 2 302 and the swing plate 301 more stable.

[0059] Furthermore, if Figures 1-4 As shown, the swing plate 301 of the present invention is provided with extension bosses 3010 at both ends of the deflection limit seat 1 500 and the deflection limit seat 2 600, and the two groups of extension bosses 3010 extend into the matching grooves opened in the middle of the deflection limit seat 1 500 and the deflection limit seat 2 600, and the sliding rods 3011 are detachably connected to the side of the two groups of extension bosses 3010 close to the drive motor 100, and the corresponding deflection limit seat 1 500 is opened in the middle of the deflection limit seat 2 A slide groove 501 is provided, and a slide groove 601 is provided in the deflection limit seat 2 600. The corresponding sliding rods 3011 on both sides cooperate with the slide groove 501 and the slide groove 601 respectively, and the slide groove 501 and the slide groove 601 are separated on both sides of the vertical center line of the swing plate 301, and the slide groove 501 and the slide groove 601 are both arc-shaped, and the centers of the slide groove 501 and the slide groove 601 are both located on the axial direction of the rotating shaft 201.

[0060] When the swing plate 301 deflects, the sliding rod 3011 slides in the corresponding chute 1 501 or chute 2 601 in the direction of deflection. It should be further explained that the sliding rod 3011, the deflection limit seat 1 500, and the deflection limit seat 2 600 are all made of nylon 66. The sliding rod 3011 fully contacts both the chute 1 501 and the chute 2 601, providing frictional resistance and ensuring that the swing plate 301 remains stationary when the intermittent mechanism 300 is not moving. To increase the lifespan of the structure, the chute 1 501 and the chute 2 601 are coated with a wear-resistant coating, such as a PTFE composite coating (PTFE with 17% silicon carbide whiskers added). The sliding rod 3011 is also easily replaceable.

[0061] Furthermore, if Figure 2-Figure 4 As shown, a limiting column 101 is provided on one side of the bottom of the driving motor 100 of the present invention, 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 column 101 extends into the limiting arc groove 305 to limit the deflection of the intermittent mechanism 300. The specific deflection angle can be designed according to actual needs.

[0062] When the present invention is driven, the driving motor 100 is started to drive the rotating shaft 201 to rotate, and the rotating shaft 201 drives the swing leaf 202 to rotate continuously. The rotating shaft 201 synchronously drives the magnetic chuck 1 203 to rotate, and the driving magnet 204 in the magnetic chuck 1 203 deflects. When the driving magnet 204 is completely aligned with the driven magnet 304 in the magnetic chuck 2 302, the coupling force reaches its peak, overcoming the maximum static friction between the swing plate 301 and the deflection limit seat 1 500 and the deflection limit seat 2 600. The driving magnet 204 drives the driven magnet 304 The driven magnet 304 drives the magnetic suction cup 2 302 to rotate, and the magnetic suction cup 2 302 drives the swing plate 301 to deflect. When the swing plate 301 deflects to the set position, the limit column 101 cooperates with the limit arc groove 305 to stop the swing plate 301, and the rotating shaft 201 drives the swing leaf 202 to continue rotating. Then, the driving motor 100 drives the driving magnet 204 and the driven magnet 304 to forcibly separate. After separation, they continue to move to the set position. Then, the driving motor 100 reverses and repeats the above process to reset the swing leaf 202 and the swing plate 301.

[0063] It should be noted that the deflection angle range of the driving magnet 204 in the present invention is 0°-360°.

[0064] It should be noted that when the driving magnet 204 and the driven magnet 304 in the present invention are completely coupled, the magnetic force is designed to be greater 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 above magnetic force design value can be obtained based on the maximum static friction test in actual installation, and the magnetization can be flexibly adjusted according to actual needs.

[0065] It should be noted that the present invention is applied in scenarios with moderate load (eg, torque <5 N·m) and low speed (<100 RPM).

[0066] The present invention can achieve the control of the continuous movement of the swing blades 202 (louvers) on one plane and the intermittent movement of the swing plate 301 (louvers) on another plane through a single drive motor 100, without the need to set up multiple groups of motors. At the system integration level, it solves the system redundancy problem, reduces the size of the equipment, and reduces costs.

[0067] In another embodiment of the present invention, the magnetic attraction member comprises a driving magnet 204 and an auxiliary magnet 205, wherein a plurality of auxiliary magnets 205 are provided. The plurality of auxiliary magnets 205 are located on both sides of the driving magnet 204 and are distributed around the center of the magnetic chuck 203. The distribution angles between adjacent auxiliary magnets 205 are consistent, and the spacing angle 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. The surface magnetic strength of the auxiliary magnets 205 is much lower than the surface magnetic strength of the driven magnet 304 and the driving magnet 204.

[0068] When multiple sets of auxiliary magnets 205 are simultaneously and completely coupled with the driven magnets 304, the magnetic force is designed to be 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.

[0069] It should be noted that, in order to reduce the number of tests, it can be assumed that all auxiliary magnets 205 are evenly coupled with the driven magnet 304 to calculate the surface magnetic strength of a single auxiliary magnet 205 .

[0070] The present invention adds multiple sets of auxiliary magnets 205 so that the intermittent mechanism 300 is in a stationary state after the driving magnet 204 and the driven magnet 304 are separated. The weak attraction between the auxiliary magnets 205 and the driven magnet 304 generates a holding torque to resist external vibration, wind resistance or slight external force, and prevent the swing plate 301 from accidentally moving. Moreover, at the moment when the driving magnet 204 and the driven magnet 304 are forcibly separated, the weak coupling of the auxiliary magnets 205 can absorb part of the magnetic energy, reduce mechanical shock and noise, and avoid the mechanism shaking caused by hard separation. During the reversal and reset process, the auxiliary magnets 205 can also help the driving magnet 204 and the driven magnet 304 to realign more smoothly, reducing the "impact effect". In addition, the weak coupling traction of the auxiliary magnets 205 can provide a small amount of reset torque during the reversal and reset process (when the driving magnet 204 and the driven magnet 304 are not aligned at the beginning), helping to offset the gravitational torque generated by the deflection of the swing plate 301.

[0071] Specific as Figure 4-Figure 8 FIG. 1 shows the driving state change process of the present invention when the magnetic attraction members are the driving magnet 204 and the auxiliary magnet 205. It should be noted that since the magnetic torque has a nonlinear relationship with the alignment angle (approximately a sine function), the torque drops sharply when the alignment is not complete. Therefore, even when the driving magnet 204 and the driven magnet 304 are not aligned, part of the auxiliary magnet 205 is aligned with the driven magnet 304, and the torque supplement provided cannot meet the driving conditions.

[0072] Furthermore, the weak coupling force provided by some of the auxiliary magnets 205 and the driven magnets 304 can be used as an error range to make reasonable adjustments when designing the magnetic forces of the driving magnets 204 and the driven magnets 304 .

[0073] Furthermore, in the actual driving process, there is a partial error in the timing of the driving magnet 204 driving the driven magnet 304, which does not affect the actual blind driving process.

[0074] In another embodiment of the present invention, Figure 9 As shown, multiple sets of continuous components are added, wherein the continuous components are composed of a rotating shaft 201, a swinging 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. Multiple sets of transmission gears 400 are connected through synchronous belt transmission to achieve synchronous drive.

[0075] When driving in this embodiment, the driving motor 100 can synchronously drive multiple groups of swing leaves 202 to swing continuously.
