DETAILED DESCRIPTION

[0039] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0040] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0042] See also Figure 1-Figure 9 The present invention discloses a motor that is easy to assemble, including a housing 10, a bracket assembly, a bracket assembly, a rotor 33 assembly and a cover plate 20. The housing 10 and the cover plate 20 are integrally formed by injection molding, and the housing 10 is provided with a mounting cavity 13 and a cover opening, and the cover opening is connected to the mounting cavity 13. The housing 10 is integrally formed with a plurality of first clamping parts, and the plurality of first clamping parts are arranged on the outer peripheral wall of the cover opening. In addition, the cover plate 20 is integrally formed with a plurality of second clamping parts; the plurality of second clamping parts are correspondingly clamped with the plurality of first clamping parts.

[0043] The support assembly includes a stator frame and a coil, the stator frame is installed in the installation cavity 13, and the stator frame is fixedly connected to the inner wall of the installation cavity 13, and the coil is wound on the stator frame. The rotor 33 assembly is inserted into the stator frame and rotatably connected to the bottom wall of the installation cavity 13.

[0044] On the basis of the above structure, when the motor that is easy to assemble of the present invention is used, when assembling the motor, a coil can be wound on the stator frame, and the coil can be electrically connected to the circuit board 44 of the motor. After the stator frame and the coil are assembled, the stator frame is assembled into the installation cavity 13 of the housing 10 through the cover opening, and the rotor 33 assembly is connected to the stator frame and rotatably connected to the housing 10. After that, the cover plate 20 is covered to the cover opening position of the housing 10, and the first clamping part and the second clamping part are clamped and matched to complete the assembly of the motor. When in use, the circuit board 44 of the motor is energized, and the coil generates a magnetic field after being energized and can drive the rotor 33 assembly to achieve power output.

[0045] Since the motor housing 10 and the cover plate 20 of the present application are integrally formed by the injection molding process, the assembly of the housing 10 and the cover plate 20 is directly formed by the injection molding process with the first clamping part and the second clamping part being integrally formed, and no further processing is required later. In addition, during the processing, the setting positions of the first clamping part and the second clamping part are relatively fixed during the molding process. Therefore, during the later clamping assembly, the first clamping part and the second clamping part at the corresponding positions can be directly clamped. Compared with the prior art that requires additional hole processing on the housing 10 and the cover plate 20 after molding by riveting, in the present application, the housing 10 and the cover plate 20 do not need to be processed again and can be directly assembled. The assembly accuracy is high, and the assembly is directly assembled by clamping, and the assembly difficulty is low.

[0046] In addition, it should be noted that, compared with the structure of the housing 10 and the cover plate 20 made of sheet metal in the prior art, a larger deformation will occur during the processing of the hole position, which will affect the stability of the motor after assembly. Therefore, the housing 10 and the cover plate 20 of this embodiment are both formed by injection molding, so the housing 10 and the cover plate 20 are both made of plastic material, and the plastic material itself has a certain elastic tension. When the first clamping part and the second clamping part are correspondingly clamped or detached, the first clamping part and the second clamping part can adapt to the external force deformation, so that it is not easy to be damaged during the disassembly process, and it is convenient to re-assemble.

[0047] Further, the bracket assembly includes a stator frame, a first magnet 46 and a second magnet 47, and the stator frame includes a first frame 41 and a second frame 42. The first frame 41 is provided with a first winding seat and a first positioning plate 411, and the first positioning plate 411 is protruded from the outer periphery of the first winding seat. In addition, the second frame 42 is provided with a second winding seat and a second positioning plate 421, and the second positioning plate 421 is protruded from the outer periphery of the second winding seat. When the first frame 41 and the second frame 42 are assembled, the first positioning plate 411 on the first frame 41 and the second positioning plate 421 of the second frame 42 can be assembled, the first positioning plate 411 is provided with a first positioning column 413, the second positioning plate 421 is provided with a first positioning hole, and the first positioning column 413 is connected to the first positioning hole, so that the first frame 41 and the second frame 42 are positioned and connected. The coil can be wound outside the first frame 41 and the second frame 42 , and the first positioning plate 411 and the second positioning plate 421 can be used to prevent the coil from being separated after being wound around the first frame 41 and the second frame 42 .

[0048] Specifically, the first magnet 46 is provided with a first magnetic circle and a plurality of first magnetic blocks 461, and the plurality of first magnetic blocks 461 are arranged at intervals around the circumference of the first magnetic circle. The second magnet 47 is provided with a second magnetic circle and a plurality of second magnetic blocks 471; the plurality of second magnetic blocks 471 are arranged at intervals around the circumference of the second magnetic circle. The first magnet 46 and the second magnet 47 can be assembled to the first frame 41 and the second frame 42 of the stator frame. During assembly, the first magnetic circle and the second magnetic circle are clamped between the first positioning plate 411 and the second positioning plate 421, so that the plurality of first magnetic blocks 461 extend into the first winding seat and are arranged along the inner circumferential wall of the first winding seat, and the plurality of second magnetic blocks 471 extend into the second winding seat and are arranged along the inner circumferential wall of the second winding seat.

[0049] On the basis of this structure, the bracket assembly can be assembled outside the casing 10. When assembling the stator frame and the first magnet 46, the first magnetic circle of the first magnet 46 is placed on the first positioning plate 411, so that the multiple first magnetic blocks 461 on the first magnetic circle extend into the first frame 41. In addition, the second magnetic circle of the second magnet 47 is placed on the second positioning plate 421, so that the multiple second magnetic blocks 471 of the second magnetic circle extend into the second frame 42. Then the first frame 41 and the second frame 42 are assembled with the first positioning plates 411 and the second positioning plates 421. In this way, only the first frame 41 and the second frame 42 need to be processed separately, and the coil structure is wound on the corresponding first winding seat and the second winding seat to form the stator structure. The first magnetic circle and the second magnetic circle are clamped by the first positioning plates 411 and the second positioning plates 421 of the first frame 41 and the second frame 42, and the assembly of the stator assembly and the magnet is completed at one time, thereby simplifying the assembly process.

[0050] When the motor is working, the coils on the first winding seat and the second winding seat can be electrically connected to the circuit board 44 of the motor. After the coils are energized, a changing magnetic field is generated that interacts with the fixed magnetic field generated by the first magnet 46 and the second magnet 47 to drive the rotor 33 assembly to rotate, and the rotation process of the rotor 33 assembly is stable.

[0051] The first magnetic ring and the second magnetic ring are positioned by the first positioning plate 411 and the second positioning plate 421 to prevent the first magnet 46 and the second magnet 47 from shifting after assembly. In addition, multiple magnetic blocks are embedded together to form an integral structure, which has higher mechanical strength than a single large permanent magnet and can withstand greater external forces such as centrifugal force and impact force. And through the combination of multiple magnetic blocks, a stronger magnetic field can be generated in a limited space.

[0052] Furthermore, a first positioning plate 411 may be provided at the top and bottom ends of the first skeleton 41, and a second positioning plate 421 may be provided at the top and bottom ends of the second skeleton 42; a first magnet 46 may be provided at the top and bottom ends of the first skeleton 41; a second magnet 47 may be provided at the top and bottom ends of the second skeleton 42; the first magnetic ring located at the bottom end of the first skeleton 41 and the second magnetic ring located at the top end of the second skeleton 42 are clamped between the first positioning plate 411 and the second positioning plate 421.

[0053] During assembly, in the first skeleton 41, the first magnetic circle of the upper first magnet 46 is positioned and connected to the first positioning plate 411 at the top, and the first magnetic circle of the lower first magnet 46 is positioned and connected to the first positioning plate 411 at the bottom, and the multiple first magnetic blocks 461 of the upper and lower first magnets 46 can all be extended into the first winding seat and assembled into the first winding seat in an up and down interlocking manner. The up and down interlocking manner can make the magnetic flux more concentrated and enhance the strength of the magnetic field, thereby improving the torque and power density of the motor, allowing the motor to output greater power in the same volume, or reduce the volume of the motor under the same power requirements.

[0054] Similarly, in the second skeleton 42, the second magnetic circle of the upper second magnet 47 is positioned and connected to the second positioning plate 421 at the top, and the second magnetic circle of the lower second magnet 47 is positioned and connected to the second positioning plate 421 at the bottom, and the multiple second magnetic blocks 471 of the upper and lower second magnets 47 can all be extended into the second winding seat and assembled into the second winding seat in an up and down interlocking manner. The up and down interlocking manner can make the magnetic flux more concentrated and enhance the strength of the magnetic field, thereby improving the torque and power density of the motor, allowing the motor to output greater power in the same volume, or reduce the volume of the motor under the same power requirements.

[0055] In addition, after the first magnet 46 and the second magnet 47 are assembled to the first frame 41 and the second frame 42, the multiple magnetic blocks of the first magnet 46 and the multiple magnetic blocks of the second magnet 47 are assembled using a top-to-bottom interlocking structure, which increases the heat dissipation surface area, which is beneficial to the heat dissipation of the first magnet 46 and the second magnet 47. During the operation of the motor, the heat generated by the permanent magnet can be more effectively transferred to the surrounding environment through the gaps and surfaces between the magnetic blocks, reducing the working temperature of the permanent magnet, avoiding the degradation of the performance of the permanent magnet due to overheating, such as demagnetization, and other problems, so that the service life is longer.

[0056] Furthermore, in order to stabilize the assembly structure of the first magnet 46 and the second magnet 47, a first positioning column 413 may be provided on the first positioning plate 411, and a first positioning hole may be provided on the second positioning plate 421, and through holes may be provided on the first magnetic circle and the second magnetic circle. After the first magnetic circle and the second magnetic circle are assembled between the first positioning plate 411 and the second positioning plate 421, the first positioning column 413 on the first positioning plate 411 may pass through the through holes of the first magnetic circle and the second magnetic circle in turn to be inserted into the first positioning hole, thereby realizing the positioning assembly of the first magnetic circle and the second magnetic circle.

[0057] The first positioning post 413 on the first positioning plate 411 passes through the through-holes of the first magnetic circle and the second magnetic circle and then passes through the first positioning hole of the second positioning plate 421, so as to firmly fix the magnet in a predetermined position, prevent the magnet from being displaced, falling off or damaged due to factors such as vibration and centrifugal force during the operation of the motor, avoid the adverse effect of abnormal magnetic field caused by the change of magnet position on the motor performance, and ensure the reliable operation of the motor. When the first magnet 46 and the second magnet 47 are assembled with the first positioning plate 411 and the second positioning plate 421, they need to correspond to the first positioning post 413 of the first positioning plate 411 and the first positioning hole of the second positioning plate 421. Accurate positioning and installation can ensure that the relative positions between the magnets are accurate and make the magnetic field distribution more uniform and stable.

[0058] Furthermore, a second positioning hole can be provided on the first positioning plate 411, and a second positioning column 423 can be provided on the second positioning plate 421. The second positioning column 423 passes through the through hole to be inserted into the second positioning hole. In this way, the first positioning column 413 on the first positioning plate 411 and the first positioning hole of the second positioning plate 421, in conjunction with the second positioning hole on the first positioning plate 411 and the second positioning column 423 on the second positioning plate 421, adopt an upper and lower interlocking structure for positioning, so that the positioning structure is more accurate.

[0059] Furthermore, a third positioning hole 131 is provided on the bottom wall of the installation cavity 13, and a second positioning column 423 of a second positioning plate 421 located at the bottom end of the second frame 42 is inserted into the third positioning hole 131, so that when the stator frame and the installation cavity 13 are assembled, the second positioning column 423 on the second positioning plate 421 is positioned with the third positioning hole 131 of the installation cavity 13 to stabilize the assembly structure of the stator frame.

[0060] Furthermore, a first wiring seat 412 is provided on the side of the first positioning plate 411 at the top of the first frame 41, and a second wiring seat 422 is provided on the side of the second positioning plate 421 at the top of the second frame 42;

[0061] Specifically, the first wiring seat 412 and the second wiring seat 422 are both provided with a first wiring hole 43 and a second wiring hole; the first wiring hole 43 is arranged in the horizontal direction, and the second wiring hole is arranged in the vertical direction, and the first wiring hole 43 and the second wiring hole are interconnected.

[0062] In this way, the upper terminal of the coil wound on the first winding seat of the first skeleton 41 can be led out downward through the second wiring hole on the first wiring seat 412, while the lower terminal of the coil can be directly led out through the first wiring hole 43; at the same time, the upper terminal of the coil wound on the second winding seat of the second skeleton 42 can be led out downward through the second wiring hole on the second wiring seat 422, while the lower terminal of the coil can be directly led out through the second wiring hole, which facilitates the routing of the coil, and the first wiring seat 412 and the second wiring seat 422 are both arranged on the same side of the first skeleton 41 and the second skeleton 42, so that when the line structure is derived, the line can be directly connected or derived on the corresponding side, which is convenient for wiring.

[0063] It should be noted that a circuit board 44 can be installed on the above-mentioned first wiring seat 412, and the above-mentioned upper coil and lower coil can be electrically connected to the circuit board 44, and the wiring terminals of the lower coil can be guided upward through the second wiring hole of the second wiring seat 422 for wiring.

[0064] Furthermore, a wire outlet 14 and a wire outlet housing 12 may be provided on the side of the housing 10, and the wire outlet 14 is provided corresponding to the first wiring seat 412 and the second wiring seat 422, so that the wire outlet housing 12 is sealed to the wire outlet 14 during wiring; a wire outlet hole 121 is provided on the wire outlet housing 12. During wiring, the coil wiring of the first winding seat of the first frame 41 can be guided to the wire outlet 14 through the first wiring seat 412, and the coil wiring of the second winding seat of the second frame 42 can be guided to the wire outlet 14 through the second wiring seat 422. The wire outlet housing 12 is sealed to the wire outlet 14, and the internal circuit is sealed and covered, and the circuit is then led out through the wire outlet hole 121 on the wire outlet housing 12. When the internal circuit is inspected, the wire outlet housing 12 can be detached from the wire outlet 14 of the housing 10, which is convenient for inspection.

[0065] Of course, the outlet housing 12 and the housing 10 may be assembled by means of a snap-on or plug-in connection, which is convenient for assembly and disassembly.

[0066] Furthermore, the rotor 33 assembly in the present embodiment includes a rotor 33, a transmission shaft 31, and a gear mechanism 32. The rotor 33 is rotatably inserted into the positioning frame. A gear shaft 331 is provided on the rotor 33, and the gear shaft 331 is connected to the transmission shaft 31 through the gear mechanism 32; the transmission shaft 31 extends out of the cover plate 20, so that when the rotor 33 rotates, the gear shaft 331 can be driven to rotate, and the gear shaft 331 drives the gear mechanism 32 to transmit to the transmission shaft 31, and the transmission shaft 31 forms the power output shaft of the motor, which drives the external rotating parts to rotate, so that the rotation output state of the motor is stable.

[0067] Specifically, support plates 45 are provided on both sides of the stator frame. Since the gear mechanism 32 is installed on the stator frame, when the cover plate 20 covers the cover opening of the casing 10, in order to prevent the cover plate 20 from moving downward and interfering with the gear mechanism 32 on the stator frame, a support plate 45 is provided on the stator frame to abut against the bottom end of the cover plate 20 after the cover plate 20 covers the cover opening, so as to prevent the cover plate 20 from pressing down the gear mechanism 32 and causing obstruction of the gear transmission.

[0068] Of course, a rotor through hole 24 may also be provided on the cover plate 20, and a flange 22 structure may be provided around the periphery of the rotor through hole 24, so that when the transmission shaft 31 passes through, it may be transmitted through the rotor through hole 24, and be limited in the circumferential direction by the flange 22 structure. In this way, during the rotation of the rotor 33, the rotation of the transmission shaft 31 is limited by the flange 22, thereby reducing circumferential vibration and reducing working noise.

[0069] Furthermore, the first clamping portion includes a clamping block 11, and the corresponding second clamping portion includes a buckle 21. The clamping block 11 is clamped to the buckle 21. When the cover plate 20 and the casing 10 are clamped and assembled, the clamping block 11 on the casing 10 is clamped into the buckle 21 on the cover plate 20, so that the buckle assembly is realized, the vibration caused by operation is smaller, and the noise of the whole machine is low.

[0070] Specifically, the above-mentioned buckle 21 includes a protruding first clamping step 211 and clamping arms 212 on both sides of the first clamping step 211. The two clamping arms 212 are connected by brackets and connecting arms to form a clamping socket 213 structure. The corresponding bottom end of the clamping block 11 is provided with a second clamping step 111, and the second clamping step 111 is inclined upward. In this way, when clamping, the inclined surface of the clamping block 11 can guide the clamping block 11 to be clamped into the clamping socket 213. The clamping arms 212 on both sides are limited on both sides of the clamping block 11, and the first clamping step 211 and the second clamping step 111 are pressed against each other in the upper and lower limit positions, so that the clamping structure is more stable.

[0071] A positioning groove 23 may be provided on the edge of the cover plate 20, and a positioning piece 15 may be provided on the outer peripheral edge of the cover opening correspondingly; the positioning piece 15 is inserted into the positioning groove 23. When the cover plate 20 and the cover opening are assembled, the positioning piece 15 is inserted into the positioning groove 23 to guide the buckle 21 to correspond to the clamping block 11, thereby improving the assembly accuracy. At the same time, the positioning piece 15 supports the edge position of the cover plate 20 at the bottom, thereby preventing the cover plate 20 made of plastic material from being deformed at the edge position.

[0072] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
