Description

Technical Field

[0001] This invention relates to the field of motor technology, and in particular to a motor and an air conditioner having the same. Background Technology

[0002] In related technologies, electric motors, as crucial devices for converting electrical energy into mechanical energy, play a key role in various fields such as compressors, refrigeration equipment, and household appliances. In existing technologies, during the soldering of power cords, solder can easily explode and fly into the gaps between the stator and rotor, causing malfunctions in the motor. Furthermore, to prevent the power cord from scraping the rotor, additional limiting structures are usually required to mitigate the risk, thus increasing costs. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a motor in which the power cord is externally mounted, reducing the risk of the power cord rubbing against the rotor assembly, eliminating the need for additional limiting designs, thereby reducing production and processing costs and improving reliability and stability.

[0004] The present invention also proposes an air conditioner, which includes the aforementioned motor.

[0005] According to an embodiment of the present invention, a motor includes: a plastic-coated housing, the plastic-coated housing including a body, a mating portion, and a lead-out portion, the mating portion and the lead-out portion being disposed on the same end face in the axial direction of the body, the mating portion being disposed on the radially inner side of the body, and the lead-out portion being located on the radially outer side of the mating portion; a stator assembly disposed within the plastic-coated housing, and the stator assembly having winding wires; a lead-out pin, the lead-out pin being inserted through the lead-out portion in the axial direction of the body, one end of the lead-out pin being electrically connected to the winding wires; and a power line, the power line being electrically connected to the end of the lead-out pin opposite to the winding wires.

[0006] According to the present invention, the motor has an externally mounted power supply line by positioning the lead wire portion radially outside the mating portion and connecting the power supply line to the winding wire of the stator assembly via a lead wire pin. This achieves two advantages: firstly, it isolates the power supply line from the cavity defined by the main body, reducing the risk of the power supply line rubbing against the rotor assembly. It also avoids the additional design required in the prior art, such as using heat-shrink tubing on the power supply line or designing wire-blocking posts on the plastic-coated shell, thus reducing the production cost of the plastic-coated shell. Secondly, it prevents solder from flying everywhere and entering the cavity defined by the main body when connecting the power supply line, avoiding blockages or the need for additional solder cleaning, thereby improving the reliability and stability of the motor and ensuring its normal operation.

[0007] In addition, the motor according to the present invention may also have the following additional technical features:

[0008] In some embodiments, the lead wire portion has a first stop on the side opposite to the body, the first stop extending along the edge of the lead wire portion, the lead pin being located inside the first stop, and the side of the first stop opposite to the axis of the body having an opening for the power line to be led out.

[0009] In some embodiments, the motor further includes: a cover plate, the cover plate being disposed on the side of the lead wire portion away from the body, the cover plate having a second stop on the side facing the lead wire portion, the second stop extending along the edge of the cover plate and located outside the first stop and fitting against the outer peripheral wall of the first stop.

[0010] In some embodiments, a wire groove is provided on the side of the lead wire portion away from the body. The wire groove is disposed adjacent to the opening and one end is in communication with the opening, while the other end extends toward the lead pin. A portion of the power wire is adapted to be located within the wire groove.

[0011] In some embodiments, a positioning protrusion is provided on the side of the lead wire portion away from the body, the positioning protrusion is disposed adjacent to the opening, and the wire groove is disposed on the positioning protrusion.

[0012] In some embodiments, the cover plate has a stop protrusion on the side facing the lead wire portion, the stop protrusion being opposite to and abutting against the area of ​​the lead wire portion where the wire groove is provided.

[0013] In some embodiments, the lead-out pins are a plurality of pins spaced apart along the circumferential direction of the body, and the wire grooves are a plurality of grooves corresponding one-to-one with the plurality of lead-out pins.

[0014] In some embodiments, a water-blocking protrusion is provided on the side of the lead wire portion facing away from the body, the water-blocking protrusion extending along the width direction of the opening and spaced apart from the opening in the radial direction of the body.

[0015] In some embodiments, the plastic-coated shell further includes: mounting ears, which are disposed on the outer peripheral wall of the body and are a plurality of them spaced apart along the circumferential direction of the body.

[0016] In some embodiments, the lead wire portion is disposed between two adjacent mounting ears among a plurality of mounting ears.

[0017] In some embodiments, the power cord is soldered to the lead-out pin; or, the power cord is connected to the lead-out pin via a mating terminal.

[0018] The present invention also proposes an air conditioner having the above-described embodiments.

[0019] According to an embodiment of the present invention, an air conditioner equipped with the aforementioned motor, by positioning the lead wire portion radially outside the mating portion, and connecting the power cord to the winding wire of the stator assembly via lead pins, can achieve external power cord placement. On the one hand, this isolates the power cord from the cavity defined by the main body, reducing the risk of the power cord rubbing against the rotor assembly. It also avoids the additional design required in the prior art, such as using heat shrink tubing on the power cord or designing wire-blocking posts on the plastic casing, thus reducing the production and processing costs of the plastic casing. On the other hand, it prevents solder from flying everywhere and entering the cavity defined by the main body when connecting the power cord, avoiding blockage problems or the need for additional solder cleaning, thereby improving the reliability and stability of the motor and ensuring its normal operation.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] The motor 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0041] like Figure 2As shown, the motor 100 according to an embodiment of the present invention includes a plastic-coated housing 1, a stator assembly 4, lead-out pins 2, and a power cord.

[0042] Specifically, see the attached document. Figure 3 As shown, the plastic-coated shell 1 includes a body 11, a mating part 12, and a lead wire part 13. The mating part 12 and the lead wire part 13 are located in the axial direction of the body 11 (see attached figure). Figure 3 On the same end face (in the direction shown in a), the mating part 12 is provided on the radial inner side of the body 11 and extends in a ring shape along the circumferential direction of the body 11 for mating with the bearing end cover 7 of the motor 100, and the lead wire part 13 is located on the radial outer side of the mating part 12.

[0043] Further, see Appendix Figure 2 and attached Figure 3 As shown, the stator assembly 4 is disposed inside the plastic-coated shell 1. The plastic-coated shell 1 is formed by coating the stator assembly 4 with insulating material through processes such as injection molding. The plastic-coated shell 1 and the stator assembly 4 form a stator assembly 200. The plastic-coated shell 1 has the functions of insulation and protection, and can also enhance the mechanical strength of the stator assembly 200, and improve the electrical performance and safety of the stator assembly 200.

[0044] Furthermore, see the attached document. Figure 3 As shown, the stator assembly 4 has winding wires and a stator core. The winding wires are wound around the stator core. When the winding wires are energized, the stator core can generate a rotating magnetic field. The plastic-coated shell 1 is formed by coating the stator assembly 4, which has a stator core and winding wires, with insulating material through processes such as injection molding.

[0045] Furthermore, the lead-out pin 2 is inserted along the axial direction of the body 11 onto the lead-out section 13. One end of the lead-out pin 2 is electrically connected to the winding wire, and the power supply line is electrically connected to the end of the lead-out pin 2 that is away from the winding wire. The power supply line is used to transfer electrical energy from the power source to the lead-out pin 2, and then to the winding wire of the stator assembly 4 through the lead-out pin 2, so as to drive the motor 100 to work. This eliminates the need for the plastic-coated shell 1 to be injected with the power supply line, improves the manufacturability of the plastic-coated shell 1, reduces the defect rate of the plastic-coated shell 1, reduces the turnover difficulty of the plastic-coated shell 1, improves the injection molding efficiency of the plastic-coated shell 1, and facilitates the production and processing of the motor 100.

[0046] It should be noted that the reference appendix... Figure 3As shown, the rotor assembly 5 is rotatably disposed within the stator assembly 200, and the rotating shaft 6 passes through and is connected to the rotor assembly 5. The rotor assembly 5 includes a rotor core 51 and a rotor magnet 52. The rotor magnet 52 can be a permanent magnet or an electromagnet. When the stator assembly 4 is energized, it can generate a rotating magnetic field. The rotor magnet 52 can respond to the rotating magnetic field generated by the stator assembly 4, generate magnetic force, and cause the rotor core 51 to rotate, thereby providing torque and driving the rotating shaft 6 to rotate.

[0047] Understandably, by positioning the lead wire portion 13 radially outside the mating portion 12, and connecting the power wire to the winding wire of the stator assembly 4 via the lead wire pin 2, the power wire can be externally positioned. On the one hand, this keeps the power wire away from the gap between the stator assembly 4 and the rotor assembly 5, isolating the power wire from the cavity defined by the body 11, reducing the risk of the power wire rubbing against the rotor assembly 5. It also avoids the additional design required in the prior art, such as using heat shrink tubing on the power wire or designing wire-blocking posts on the plastic shell, thus reducing the production and processing cost of the plastic shell 1. On the other hand, it prevents solder from flying everywhere and entering the cavity defined by the body 11 when connecting the power wire, avoiding blockage problems or the need for additional solder cleaning, thereby ensuring the normal operation of the motor 100 and reducing the production, processing, and maintenance costs of the motor 100.

[0048] According to the embodiment of the present invention, the motor 100, by positioning the lead wire portion 13 radially outside the mating portion 12, and connecting the power cord to the winding wire of the stator assembly 4 via the lead wire pin 2, can realize the external placement of the power cord. On the one hand, this isolates the power cord from the cavity defined by the body 11, reducing the risk of the power cord rubbing against the rotor assembly 5. It also avoids the additional design of using heat shrink tubing on the power cord or designing wire-blocking posts on the plastic shell, as is done in the prior art, thus reducing the production and processing cost of the plastic shell 1. On the other hand, it can prevent solder from flying everywhere into the cavity defined by the body 11 when connecting the power cord, avoiding blockage problems or the need for additional solder cleaning, thereby improving the reliability and stability of the motor 100 and ensuring the normal operation of the motor 100.

[0049] In some embodiments of the present invention, reference is made to the appendix. Figure 2As shown, a first stop 131 is provided on the side of the lead wire portion 13 facing away from the main body 11. The first stop 131 extends along the edge of the lead wire portion 13, and the lead pin 2 is located inside the first stop 131. The first stop 131 can protect the lead pin 2 to a certain extent. The side of the first stop 131 facing away from the axis of the main body 11 has an opening 132 for the power cord to be led out, which allows the power cord to be led out in the radial direction of the main body 11 instead of in the axial direction of the main body 11. This can relatively reduce the axial space occupied by the power cord in the plastic shell 1, and facilitate the internal structural layout of the plastic shell 1.

[0050] In a further embodiment of the invention, reference is made to the appendix. Figure 1 As shown, the motor 100 also includes a cover plate 3, which covers the side of the lead wire portion 13 facing away from the main body 11. The cover plate 3 and the lead wire portion 13 together define a placement space, within which the lead pin 2 and the power cord are located, thus protecting the lead pin 2 and the power cord. Further, refer to the attached drawing... Figure 2 and attached Figure 4 As shown, the cover plate 3 has a second stop 31 on the side facing the lead wire portion 13. The second stop 31 extends along the edge of the cover plate 3 and is located outside the first stop 131 and fits against the outer peripheral wall of the first stop 131. Through the cooperation of the first stop 131 and the second stop 31, misalignment or breakage of the cover plate 3 during assembly can be avoided, ensuring the accuracy and stability of the assembly of the cover plate 3 and the lead wire portion 13. It can also prevent dust or other impurities from entering the placement space to a certain extent, and prevent dust or other impurities from affecting the normal connection between the lead wire pin 2 and the power cord.

[0051] It should be noted that, as Figure 2 and Figure 4 As shown, the second stop 31 is located outside the first stop 131, which can better protect the lead wire part 13 and prevent the placement space defined by the lead wire part 13 and the cover plate 3 from being reduced due to the presence of the second stop 31, thereby ensuring the normal placement of the lead wire pin 2 and the power cord.

[0052] In a further embodiment of the invention, reference is made to the appendix. Figure 2 and attached Figure 4 As shown, a wire groove 133 is provided on the side of the lead-out portion 13 facing away from the main body 11. The wire groove 133 is located adjacent to the opening 132 and one end is connected to the opening 132, while the other end extends toward the lead-out pin 2. The power cord portion is adapted to be located within the wire groove 133. The wire groove 133 can limit the power cord, allowing the power cord to extend along the extension direction of the wire groove 133 (see attached diagram). Figure 4Extending in the direction shown (b), it provides a basis for neat wiring of the power cord, which helps to improve the reliability and manufacturability of the plastic-coated shell 1.

[0053] In a further embodiment of the invention, reference is made to the appendix. Figure 2 As shown, a positioning protrusion 134 is provided on the side of the lead wire portion 13 facing away from the main body 11. The positioning protrusion 134 is located near the opening 132, and the wire groove 133 is located on the positioning protrusion 134. It can be understood that the positioning protrusion 134 has several advantages. First, the positioning protrusion 134 can strengthen the structural strength of the lead wire portion 13 and ensure the structural reliability of the lead wire portion 13. Second, the wire groove 133 is located on the positioning protrusion 134, which can ensure the limiting effect of the wire groove 133 on the power line, and make the inner bottom wall of the wire groove 133 flush with the part of the lead wire portion 13 that does not have the positioning protrusion 134, so as to avoid the presence of the wire groove 133 encroaching on the internal space of the plastic shell 1 and avoiding affecting the structural reliability of the main body 11. Third, the positioning protrusion 134 can increase the depth of the wire groove 133, improve the limiting effect of the wire groove 133 on the power line, and ensure the stability of the power line.

[0054] In a further embodiment of the invention, reference is made to the appendix. Figure 4 As shown, the cover plate 3 has a stop protrusion 32 on the side facing the lead wire portion 13. The stop protrusion 32 is opposite to and abuts against the area of ​​the lead wire portion 13 where the wire groove 133 is provided. It can be understood that the wire groove 133 is provided on the side of the lead wire portion 13 away from the body 11. The provision of the wire groove 133 will increase the gap between the lead wire portion 13 and the cover plate 3. By providing a stop protrusion 32 on the side of the cover plate 3 facing the lead wire portion 13, the gap between the lead wire portion 13 and the cover plate 3 can be reduced, so that the stop protrusion 32 can stop the power wire located in the wire groove 133, preventing the power wire from coming out of the wire groove 133, and further improving the limiting effect of the wire groove 133 on the power wire. For example, referring to the attached reference... Figure 2 and attached Figure 4 As shown, a positioning protrusion 134 is provided on the side of the lead wire portion 13 away from the main body 11. The wire groove 133 is provided on the positioning protrusion 134. The stop protrusion 32 abuts against the part of the positioning protrusion 134 where the wire groove 133 is not provided, and is separated from the inner bottom wall of the wire groove 133 to ensure the arrangement space of the power line.

[0055] In a further embodiment of the invention, reference is made to the appendix. Figure 2 As shown, there are multiple lead-out pins 2 spaced apart along the circumferential direction of the body 11, and multiple wire grooves 133 corresponding one-to-one with the multiple lead-out pins 2, which can separate and limit the multiple sub-wires of the power cord, ensuring the correct wiring of the multiple sub-wires. In a specific example, refer to the attached diagram. Figure 2As shown, there are three lead-out pins 2 spaced apart along the circumferential direction of the body 11, which are electrically connected to the U, V and W lines of the power cord respectively. There are three wire grooves 133 corresponding to the three lead-out pins 2, which can be used to place the U, V and W lines of the power cord respectively, so that the U, V and W lines are spaced apart and respectively limited to ensure the correct wiring of the power cord.

[0056] It should be noted that by concentrating the power cord on the lead-out section 13, the length of the power cord can be reduced, the ease of operation can be improved, the amount of lead-out section 13 used can be reduced, and thus the production and processing cost of the motor 100 can be reduced.

[0057] In a further embodiment of the invention, reference is made to the appendix. Figure 2 and attached Figure 4 As shown, a water-blocking boss 135 is provided on the side of the lead wire portion 13 facing away from the main body 11. The water-blocking boss 135 extends along the width direction of the opening 132 (see attached diagram). Figure 2 The lead pin 2 extends in the direction c shown and is spaced apart from the opening 132 in the radial direction of the body 11. This reduces the probability of water, dust or other impurities entering the lead wire portion 13 from the opening 132, thus protecting the motor 100 and improving the reliability and stability of the motor 100, thereby avoiding affecting the effectiveness of the lead pin 2.

[0058] In a specific example, such as Figure 4 As shown, the stop protrusion 32 is located on the side of the water-blocking boss 135 away from the axis of the main body 11. It can be understood that the power cord extends from the lead-out pin 2 to the opening 132. First, due to the presence of the water-blocking boss 135, the part of the power cord located in the wire groove 133 bends towards the direction close to the cover plate 3, so that the surfaces of the cover plate 3 and the water-blocking boss 135 facing each other together fix the power cord. Then, due to the presence of the stop protrusion 32, the part of the power cord located in the wire groove 133 bends towards the direction away from the cover plate 3, so that the surfaces of the stop protrusion 32 and the guide groove facing each other together fix the power cord. By bending the power cord multiple times, a maze-shaped structure can be formed, which improves the fixing effect of the power cord and ensures the protective effect of the cover plate 3 and the lead-out part 13 on the power cord and the lead-out pin 2.

[0059] In some embodiments of the present invention, reference is made to the appendix. Figure 1 and attached Figure 2As shown, the plastic-coated shell 1 also includes mounting ears 14. Multiple mounting ears 14 are located on the outer peripheral wall of the body 11 and are spaced apart along the circumferential direction of the body 11. This facilitates the fixing and installation of the motor 100. The multiple mounting ears 14 create multiple mounting positions along the circumferential direction of the body 11, allowing the stator assembly 200 with the plastic-coated shell 1 to be fixedly installed at multiple points along the circumferential direction of the body 11. This enhances the connection stability between the stator assembly 200 and the connected components. Simultaneously, the force between the plastic-coated shell 1 and the connected components can be distributed to the multiple mounting ears 14, thereby reducing the stress generated by each mounting ear 14, lowering the risk of damage to the mounting ears 14, and extending the service life of the motor 100.

[0060] In a further embodiment of the invention, reference is made to the appendix. Figure 2 As shown, the lead wire section 13 is located between two adjacent mounting ears 14 among a plurality of mounting ears 14, providing a lead wire space for the power wires led out in the radial direction of the body 11, which facilitates the lead wires out.

[0061] In some embodiments of the present invention, reference is made to the appendix. Figure 1 As shown, the plastic-coated shell 1 is a single piece, which can be manufactured in one piece through processes such as injection molding, reducing production steps and thus improving production efficiency. It also enhances the connection strength between the body 11, the mating part 12, and the lead wire part 13, thereby improving the overall structural stability and reliability of the plastic-coated shell 1.

[0062] In some embodiments of the present invention, the power cord is welded to the lead-out pin 2. The connection is achieved by heating and melting a low-melting-point metal solder (usually a tin-based alloy) and then penetrating and filling the gap at the metal connection. The connection can be formed by the melting of the solder and the wetting and diffusion of the metal surface. The equipment is simple, easy to operate, and has good manufacturability, which can ensure the reliability of the connection between the power cord and the lead-out pin 2.

[0063] In other embodiments of the present invention, the power cord and the lead-out pin 2 are connected by a mating terminal. The mating terminal has a compact structure, is easy to install and disassemble, can save space, and ensures a firm and reliable connection between the power cord and the lead-out pin 2.

[0064] It should be noted that the lead-out pin 2 and the winding wire of the stator assembly 200 can also be connected by welding or by connecting through mating terminals to ensure the reliability of the connection between the lead-out pin 2 and the winding wire of the stator assembly 200 and to ensure manufacturability.

[0065] The present invention also proposes an air conditioner having the motor 100 described in the above embodiments.

[0066] The air conditioner includes an indoor unit and an outdoor unit. The motor 100 can be either a motor 100 that drives the fan in the outdoor unit or a motor 100 that drives the impeller in the indoor unit. Since the motor 100 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0067] According to an embodiment of the present invention, the air conditioner is equipped with the aforementioned motor 100. By positioning the lead wire portion 13 radially outside the mating portion 12, and connecting the power cord to the winding wire of the stator assembly 4 via the lead wire pin 2, the power cord can be externally mounted. On the one hand, this isolates the power cord from the cavity defined by the body 11, reducing the risk of the power cord rubbing against the rotor assembly 5. It also avoids the additional design required in the prior art, such as using heat shrink tubing on the power cord or designing wire-blocking posts on the plastic shell, thus reducing the production and processing cost of the plastic shell 1. On the other hand, it prevents solder from flying everywhere and entering the cavity defined by the body 11 when connecting the power cord, avoiding blockage problems or the need for additional solder cleaning, thereby improving the reliability and stability of the motor 100 and ensuring the normal operation of the motor 100.

[0068] The other components and operations of the motor 100 and air conditioner according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0069] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
