Description

Technical Field

[0001] This invention relates to the field of commutation deflection high-speed permanent magnet motors for vacuum cleaners, specifically a commutation deflection high-speed permanent magnet motor for vacuum cleaners. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. In circuit diagrams, it is represented by the letter M (D in older standards). Its main function is to generate driving torque, serving as a power source for electrical appliances or various machines. A generator, represented by the letter G, converts mechanical energy into electrical energy. A permanent magnet DC motor also consists of stator poles, a rotor, brushes, and a housing. The stator poles use permanent magnets (permanent steel), made of materials such as ferrite, AlNiCo, and NdFeB. Based on their structural form, they can be divided into cylindrical and block-type types. Most motors used in VCRs and VCRs use cylindrical magnets, while motors used in power tools and automotive electrical appliances mostly use block-type magnets. The rotor is generally made of stacked silicon steel sheets and has fewer slots than that of an electromagnetic DC motor. Low-power motors used in VCRs and VCRs mostly have 3 slots, while higher-end models have 5 or 7 slots. The enameled wire is wound between two slots of the rotor core (three slots mean three windings), and each joint is soldered to the metal plates of the commutator. The brushes are conductive components connecting the power supply to the rotor windings, possessing both conductivity and wear resistance. Permanent magnet motors use single-element metal plates, metal-graphite brushes, or electrographite brushes. Permanent magnet DC motors used in VCRs employ electronic speed control circuits or centrifugal speed control devices.

[0003] Existing vacuum cleaners using high-speed permanent magnet motors with commutation deflection employ multiple connecting rods for installation. This makes docking with the vacuum cleaner difficult and inconvenient, and the lack of support after installation leads to significant wobbling during use. Over time, this can cause the connections to loosen, affecting normal operation. Furthermore, the lack of support at the installation location requires manual assistance, which can easily cause misalignment, reducing practicality. Additionally, excess wires are prone to tangling and damage over time, posing a higher risk and failing to meet the needs of modern users. Summary of the Invention

[0004] The purpose of this invention is to provide a high-speed permanent magnet motor for vacuum cleaners with commutation deflection, which solves the problem mentioned in the background art that existing high-speed permanent magnet motors for vacuum cleaners with commutation deflection use multiple connecting rods for installation, making them difficult to operate and inconvenient to install when docking with a vacuum cleaner.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-speed permanent magnet motor for vacuum cleaners with commutation deflection, comprising a square box, wherein an installation mechanism is installed inside the square box;

[0006] The installation mechanism includes a first screw, a handle, a curved block, a grooved plate, a circular plate, and a curved plate;

[0007] The outer wall of the first screw is rotatably connected to the top of the square box. The top of the first screw is integrally formed with the bottom of the handle. The outer wall of the first screw is screwed in and out of the inner wall of the curved block. The bottom of the curved block is welded to the top of the groove plate. The inner wall of the groove plate is movably connected to the outer wall of the circular plate. The outer side of the circular plate is fixedly connected to the inner side of the curved plate. The top of the curved plate is rotatably connected to the bottom of the inner wall of the square box. This facilitates the installation and disassembly of the permanent magnet motor.

[0008] Preferably, a curved plate is welded to the bottom of the square box, and a bracket is integrally formed on the top of the curved plate. A permanent magnet motor is welded to the inner wall of the bracket. The curved plate provides support for the square box.

[0009] Preferably, the lower part of the outer wall of the curved plate is movably connected to the bottom groove of the bent plate. The curved plate can rotate within the bottom groove of the bent plate.

[0010] Preferably, the top of the outer wall of the permanent magnet motor is provided with an outer shell, the bottom of the outer wall of the outer shell is welded to the top of the outer wall of the permanent magnet motor, and a support mechanism is installed inside the outer shell;

[0011] The support mechanism includes bolts, sleeves, inclined plates, vertical plates, bent bars, short plates, and horizontal bars;

[0012] The outer side of the bolt is rotatably connected to the inner wall of the outer casing. The outer wall of the bolt is threadedly connected to the inner wall of the sleeve plate. The outer side of the sleeve plate is rotatably connected to the inner rear end face of the inclined plate. The outer rear end face of the inclined plate is rotatably connected to the inner side of the vertical plate. The outer wall of the vertical plate fits against the inner wall of the outer casing. The upper inner side of the vertical plate is fixedly connected to the outer side of the bent rod. One end of the bent rod is welded to the outer wall of the short plate. The inner wall of the short plate is slidably engaged with the outer wall of the crossbar. This improves the stability of the permanent magnet motor after installation.

[0013] Preferably, one end of the crossbar is welded to the inner wall of the outer casing. The outer casing provides support for the crossbar.

[0014] Preferably, an adjustment mechanism is installed on the rear end face of the permanent magnet motor;

[0015] The adjusting mechanism includes a sleeve, a rotating rod, a first gear, a second gear, a vertical rod, a second screw, and a thick plate;

[0016] The front of the sleeve is welded to the rear end face of the permanent magnet motor. The outer wall of the sleeve is rotatably connected to the outer wall of the rotating rod. One end of the rotating rod is welded to the outer side of the first gear. The outer wall of the first gear meshes with the outer wall of the second gear. The top of the second gear is welded to the bottom of the upright. The top of the upright is rotatably connected to the inner wall of the sleeve. The bottom of the second gear is fixedly connected to the top of the second screw. The outer wall of the second screw screws in and out of the inner wall of the thick plate. This allows for easy adjustment of the installation height of the permanent magnet motor.

[0017] Preferably, the outer wall of the thick plate is provided with a straight cylinder, the inner wall of the straight cylinder is welded to the outer wall of the thick plate, and the outer wall of the straight cylinder is clearance-fitted with the inner wall of the sleeve. The sleeve moves up and down through the outer wall of the straight cylinder under force.

[0018] Preferably, the outer wall of the permanent magnet motor is equipped with a placement mechanism;

[0019] The placement mechanism includes a long plate, an arc plate, and a ring;

[0020] The inner side of the long plate is welded to the outer wall of the permanent magnet motor, and the outer side of the long plate is welded to the inner side of the arc plate at equal intervals. The outer sides of the multiple arc plates are respectively welded to the inner side of the ring. This facilitates control of the position of excess wires and prevents tangling.

[0021] Compared with the prior art, the beneficial effects of the present invention are: the vacuum cleaner uses a high-speed permanent magnet motor with commutation deflection, which drives the first screw to rotate through the handle in the installation mechanism, thereby driving the curved block to move downward. The moving curved block drives the groove plate to move downward, and then the curved plate rotates outward when it is in contact with the round plate. The rotating curved plate will lock the mating connecting surface, thus completing the installation of the permanent magnet motor, eliminating the trouble of installing the connecting rod, making installation convenient and reducing the difficulty of operation.

[0022] The bolts in the support mechanism rotate under force, which in turn drives the sleeve plate to move downward. The moving sleeve plate drives the inclined plate to rotate outward, thereby causing the vertical plate to move outward. This makes the outer wall of the vertical plate abut against the connecting surface on the other side, preventing the connection from loosening after long-term use, improving the connection stability of the permanent magnet motor, and ensuring normal use.

[0023] The first gear is driven to rotate by the rotating rod in the adjustment mechanism, which in turn drives the second gear to rotate. The rotating second gear causes the second screw in the bottom hole of the bag to rotate upward. The second gear, in conjunction with the upright, drives the sleeve to move upward. The moving sleeve drives the permanent magnet motor to move upward, thus achieving a change in height. It can support itself, eliminating the trouble of manual support, avoiding installation misalignment, and improving practicality.

[0024] By placing excess wires through the inner wall of the ring in the mechanism, the inner wall space of the ring limits the wires, allowing them to swing only inside the ring. This prevents excess wires from getting tangled, avoids damage, reduces danger, and facilitates widespread use. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-6This invention provides a technical solution: a high-speed permanent magnet motor for a vacuum cleaner with commutation deflection, comprising a square box 1, an installation mechanism 2 installed inside the square box 1, the installation mechanism 2 comprising a first screw 201, a handle 202, a curved block 203, a slotted plate 204, a circular plate 205, and a curved plate 206, the upper part of the outer wall of the first screw 201 being rotatably connected to the top of the square box 1, the first screw 201 being rotated by a bearing at the top of the square box 1, the top of the first screw 201 being integrally formed with the bottom of the handle 202, the handle 202 being integrally formed with the bottom of the handle 202. 2. This facilitates the rotation of the first screw 201. The outer wall of the first screw 201 is screwed in and out of the inner wall of the curved block 203. The bottom of the curved block 203 is welded to the top of the groove plate 204. The inner wall of the groove plate 204 is movably connected to the outer wall of the circular plate 205. The circular plate 205 moves left and right on the inner wall of the groove plate 204 under force. The outer side of the circular plate 205 is fixedly connected to the inner side of the curved plate 206. The upper part of the curved plate 206 is rotatably connected to the lower part of the inner wall of the square box 1. The curved plate 206 rotates under force through the pin at the lower part of the inner wall of the square box 1.

[0034] The first screw is rotated by the handle in the installation mechanism, which in turn moves the curved block downward. The moving curved block moves the groove plate downward, and when it is in contact with the circular plate, the curved plate rotates outward. The rotating curved plate snaps into place the mating surfaces, thus completing the installation of the permanent magnet motor. This eliminates the hassle of installing the connecting rod, making installation easier and reducing the difficulty of operation.

[0035] A curved plate 10 is welded to the bottom of the square box 1. A bracket 6 is integrally formed on the top of the curved plate 10. A permanent magnet motor 7 is welded to the inner wall of the bracket 6. The lower part of the outer wall of the curved plate 206 is movably connected to the bottom slot of the curved plate 10. The top of the outer wall of the permanent magnet motor 7 is provided with a shell 8. The model of the permanent magnet motor 7 is CY-D35. The bottom of the outer wall of the shell 8 is welded to the top of the outer wall of the permanent magnet motor 7. A support mechanism 3 is installed inside the shell 8. The support mechanism 3 includes a bolt 301, a sleeve plate 302, an inclined plate 303, a vertical plate 304, a curved rod 305, a short plate 306, and a crossbar 307. The outer side of the bolt 301 is rotatably connected to the inner wall of the shell 8. The bolt 301 rotates through the bearings on the front and rear sides of the inner wall of the shell 8 under force. The inner wall of the sleeve plate 302 is threadedly connected to the outer side of the sleeve plate 302 and the inner side of the rear end face of the inclined plate 303 is rotatably connected. The inner side of the inclined plate 303 is rotated through the outer pin of the sleeve plate 303 under force. The outer side of the rear end face of the inclined plate 303 is rotatably connected to the inner side of the vertical plate 304. The outer side of the inclined plate 303 is rotated through the inner pin of the vertical plate 307 under force. The outer wall of the vertical plate 304 is in contact with the inner wall of the outer shell 8. The upper inner side of the vertical plate 304 is fixedly connected to the outer side of the bent rod 305. One end of the bent rod 305 is welded to the outer wall of the short plate 306. The inner wall of the short plate 306 is slidably engaged with the outer wall of the cross rod 307. The short plate 306 is slidably connected through the outer wall of the cross rod 307 under force. One end of the cross rod 307 is welded to the inner wall of the outer shell 8.

[0036] The bolts in the support mechanism rotate under force, which in turn drives the sleeve plate to move downward. The moving sleeve plate drives the inclined plate to rotate outward, thereby moving the vertical plate outward. This causes the outer wall of the vertical plate to abut against the connecting surface on the other side, preventing the connection from loosening after long-term use, improving the connection stability of the permanent magnet motor, and ensuring normal use.

[0037] An adjustment mechanism 4 is installed on the rear end face of the permanent magnet motor 7. The adjustment mechanism 4 includes a sleeve 401, a rotating rod 402, a first gear 403, a second gear 404, a vertical rod 405, a second screw 406, and a thick plate 407. The front side of the sleeve 401 is welded to the rear end face of the permanent magnet motor 7. The outer wall of the sleeve 401 is rotatably connected to the outer wall of the rotating rod 402. The rotating rod 402 rotates under force through a bearing on the outer wall of the sleeve 401. One end of the rotating rod 402 is welded to the outer side of the first gear 403. The outer wall of the first gear 403 meshes with the outer wall of the second gear 404. The rotation of the first gear 403 drives... The second gear 404 rotates, and the top of the second gear 404 is welded to the bottom of the upright 405. The top of the upright 405 is rotatably connected to the inner wall of the sleeve 401. The upright 405 rotates under force through the bearing on the inner wall of the sleeve 401. The bottom of the second gear 404 is fixedly connected to the top of the second screw 406. The outer wall of the second screw 406 is screwed in and out of the inner wall of the thick plate 407. The outer wall of the thick plate 407 is provided with a straight cylinder 9. The inner wall of the straight cylinder 9 is welded to the outer wall of the thick plate 407. The outer wall of the straight cylinder 9 is clearance-fitted with the inner wall of the sleeve 401. The sleeve 401 moves up and down under force through the outer wall of the straight cylinder 9.

[0038] The first gear is driven to rotate by the rotating rod in the adjusting mechanism, which in turn drives the second gear to rotate. The rotating second gear causes the second screw at the bottom of the bag to rotate upward. This, in turn, drives the upright to move the sleeve upward. The moving sleeve then drives the permanent magnet motor to move upward, thus achieving a change in height. This allows the device to support itself, eliminating the need for manual support, preventing installation misalignment, and improving practicality.

[0039] The outer wall of the permanent magnet motor 7 is equipped with a placement mechanism 5, which includes a long plate 501, an arc plate 502 and a ring 503. The inner side of the long plate 501 is welded to the outer wall of the permanent magnet motor 7, and the outer side of the long plate 501 is welded to the inner side of the arc plate 502 at equal intervals. The outer sides of multiple arc plates 502 are respectively welded to the inner side of the ring 503. The ring 503 can pass through excess wires.

[0040] By placing excess wires through the inner wall of the ring in the mechanism, the inner wall space of the ring limits the wires, allowing them to swing only inside the ring. This prevents excess wires from getting tangled, avoids damage, reduces danger, and facilitates widespread use.

[0041] In this example, when using the motor, the bottom of the curved plate 10 is first brought into contact with the connecting surface. Then, the first screw 201 is rotated by the handle 202, which in turn causes the curved block 203 to move downward. The moving curved block 203 causes the slotted plate 204 to move downward, and when it engages with the circular plate 205, the curved plate 206 rotates outward. The rotating curved plate 206 engages the contact surfaces, completing the installation of the permanent magnet motor 7. Then, the bolt 301 is rotated, which in turn causes the sleeve plate 302 to move downward. The moving sleeve plate 302 causes the inclined plate 303 to rotate outward, thereby causing the vertical plate to... 304 moves outward, so that the outer wall of the vertical plate 304 abuts against the connecting surface on the other side, improving the connection stability of the permanent magnet motor 7. When adjusting the installation height, the first gear 403 is driven to rotate by the rotating rod 402, which in turn drives the second gear 404 to rotate. The rotating second gear 404 rotates the second screw 406 at the bottom hole upward, which in turn drives the sleeve 401 to move upward through the second gear 404 and the upright rod 405. The moving sleeve 401 drives the permanent magnet motor 7 to move upward. The ring 503 can pass through the excess wire to provide support and prevent entanglement.
