For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0040] The motor 100 according to an embodiment of the present invention will be described below with reference to the drawings.
[0041] AsFigure 2 As shown, the motor 100 according to the embodiment of the utility model includes a molded case 1, a stator assembly 4, lead pins 2 and a power line.
[0042] Specifically, refer to the attached Figure 3 As shown, the plastic package 1 includes a body 11, a matching portion 12 and a lead wire portion 13, and the matching portion 12 and the lead wire portion 13 are arranged in the axial direction of the body 11 (refer to the attached Figure 3 On the same end face of the a direction shown in the figure, the matching portion 12 is arranged on the radial inner side of the main body 11 and extends in a ring shape along the circumferential direction of the main body 11, and is used to match with the bearing end cover 7 of the motor 100, and the lead wire portion 13 is located on the radial outer side of the matching portion 12.
[0043] Further, see Attachment Figure 2 and attached Figure 3 As shown, the stator component 4 is arranged in the overmolded shell 1. The overmolded shell 1 can be formed by covering the insulating material on the outside of the stator component 4 through a process such as injection molding. The overmolded shell 1 and the stator component 4 form a stator assembly 200. The overmolded shell 1 has insulating and protective functions, 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] Further, see Appendix Figure 3 As shown, the stator assembly 4 has winding wires, and the stator assembly 4 also includes a stator core, the winding wires are wound around the stator core, and when the winding wires are energized, the stator core can generate a rotating magnetic field. The overmolded shell 1 can be formed by coating the stator assembly 4 having the stator core and the winding wires with insulating material through a process such as injection molding.
[0045] Furthermore, the lead-out pin 2 is penetrated on the lead-out wire portion 13 along the axial direction of the main body 11, one end of the lead-out pin 2 is electrically connected to the winding wire, and the power line is electrically connected to the end of the lead-out pin 2 that is away from the winding wire. The power line is used to transfer electric energy from the power supply to the lead-out pin 2, and then transfer it to the winding wire of the stator assembly 4 through the lead-out pin 2, so as to drive the motor 100 to work, so that the overmolded shell 1 does not need to be injection molded together with the power line, thereby improving the manufacturability of the overmolded shell 1, reducing the defective rate of the overmolded shell 1, reducing the turnover difficulty of the overmolded shell 1, improving the injection molding efficiency of the overmolded shell 1, and facilitating the production and processing of the motor 100.
[0046] It should be noted that the reference Figure 3As shown, the rotor assembly 5 is rotatably disposed within the stator assembly 200. The rotating shaft 6 passes through the rotor assembly 5 and is connected to the rotor assembly 5. The rotor assembly 5 includes a rotor core 51 and rotor magnets 52. The rotor magnets 52 can be permanent magnets or electromagnets. After the stator assembly 4 is powered on, a rotating magnetic field can be generated. The rotor magnets 52 can respond to the rotating magnetic field generated by the stator assembly 4 to generate magnetic force, causing the rotor core 51 to rotate, thereby providing torque to drive the rotating shaft 6 to rotate.
[0047] It can be understood that by making the lead wire portion 13 located radially outside the mating portion 12, and connecting the power supply line to the winding wire of the stator assembly 4 through the lead pin 2, the external placement of the power supply line can be achieved. On the one hand, the power supply line is kept away from the gap between the stator assembly 4 and the rotor assembly 5, isolating the power supply line from the cavity defined by the body 11, reducing the risk of the power supply line being scratched by the rotor assembly 5. At the same time, the additional designs such as sleeving heat shrink tubes on the power supply line or designing wire blocking posts on the plastic housing in the prior art are avoided, reducing the production and processing cost of the plastic housing 1. On the other hand, it can prevent the solder from flying everywhere when connecting the power supply line from entering the cavity defined by the body 11, avoiding problems such as blockage or the need for additional solder cleaning, thereby ensuring the normal operation of the motor 100 and reducing the production and processing cost and maintenance cost of the motor 100.
[0048] For the motor 100 according to the embodiments of the present invention, by making the lead wire portion 13 located radially outside the mating portion 12, and connecting the power supply line to the winding wire of the stator assembly 4 through the lead pin 2, the external placement of the power supply line can be achieved. On the one hand, it isolates the power supply line from the cavity defined by the body 11, reducing the risk of the power supply line being scratched by the rotor assembly 5. At the same time, the additional designs such as sleeving heat shrink tubes on the power supply line or designing wire blocking posts on the plastic housing in the prior art are avoided, reducing the production and processing cost of the plastic housing 1. On the other hand, it can prevent the solder from flying everywhere when connecting the power supply line from entering the cavity defined by the body 11, avoiding problems such as blockage 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, referring to the attached Figure 2As shown, on the side of the lead wire portion 13 away from the body 11, there is a first rabbet 131. The first rabbet 131 extends along the edge of the lead wire portion 13. The lead pin 2 is located inside the first rabbet 131. The setting of the first rabbet 131 can protect the lead pin 2 to a certain extent. On the side of the first rabbet 131 away from the axis of the body 11, there is an opening 132 for leading out the power line, which enables the power line to be led out along the radial direction of the body 11 instead of the axial direction of the body 11, and can relatively reduce the occupation of the axial space of the plastic shell 1 by the power line, facilitating the structural layout inside the plastic shell 1.
[0050] In a further embodiment of the present utility model, referring to the attached Figure 1 As shown, the motor 100 further includes a cover plate 3. The cover plate 3 is disposed on the side of the lead wire portion 13 away from the body 11. The cover plate 3 and the lead wire portion 13 jointly define a placement space. The lead pin 2 and a part of the power line are located in the placement space, so that the cover plate 3 can protect the lead pin 2 and the power line. Further, referring to the attached Figure 2 and the attached Figure 4 As shown, on the side of the cover plate 3 facing the lead wire portion 13, there is a second rabbet 31. The second rabbet 31 extends along the edge of the cover plate 3 and is located outside the first rabbet 131 and fits with the outer peripheral wall of the first rabbet 131. Through the cooperation of the first rabbet 131 and the second rabbet 31, it is possible to avoid misalignment or step difference of the cover plate 3 during assembly, ensure the accuracy and stability of the assembly of the cover plate 3 and the lead wire portion 13, and can prevent dust or other impurities from entering the interior of the placement space to a certain extent, avoiding dust or other impurities from affecting the normal connection of the lead pin 2 and the power line.
[0051] It should be noted that, as Figure 2 and Figure 4 shown, the second rabbet 31 is located outside the first rabbet 131, which can better protect the lead wire portion 13, avoiding the reduction of the placement space jointly defined by the lead wire portion 13 and the cover plate 3 due to the existence of the second rabbet 31, thereby ensuring the normal placement of the lead pin 2 and the power line.
[0052] In a still further embodiment of the present utility model, referring to the attached Figure 2 and the attached Figure 4 As shown, on the side of the lead wire portion 13 away from the body 11, there is a wire groove 133. The wire groove 133 is disposed adjacent to the opening 132 and one end is communicated with the opening 132, and the other end extends towards the lead pin 2. A part of the power line is adapted to be located in the wire groove 133. The setting of the wire groove 133 can limit the power line, so that the power line extends along the extension direction of the wire groove 133 (refer to the attached Figure 4The outer shell 1 extends in the direction b) as shown, providing a basis for neatly arranging the power lines, which is beneficial to improving the reliability and manufacturability of the overmolded shell 1.
[0053] In a further embodiment of the present invention, refer to the attached Figure 2 As shown, a positioning protrusion 134 is provided on the side of the lead-out portion 13 facing away from the main body 11, the positioning protrusion 134 is provided adjacent to the opening 132, and the wire groove 133 is provided on the positioning protrusion 134. It can be understood that the provision of the positioning protrusion 134 has multiple advantages. First, the positioning protrusion 134 can strengthen the structural strength of the lead-out portion 13 and ensure the structural reliability of the lead-out portion 13; second, the wire groove 133 is provided on the positioning protrusion 134, and on the basis of ensuring the limiting effect of the wire groove 133 on the power cord, the inner bottom wall of the wire groove 133 can be flush with the part of the lead-out portion 13 that is not provided with the positioning protrusion 134, so as to avoid the wire groove 133 from occupying the space inside the plastic shell 1 and affecting the structural reliability of the main body 11; third, the provision of 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 cord, and ensure the stability of the power cord.
[0054] In a further embodiment of the present invention, refer to the attached Figure 4 As shown, the side of the cover plate 3 facing the lead-out portion 13 has a stop protrusion 32, and the stop protrusion 32 is opposite to and abuts against the area of the lead-out portion 13 provided with the wire groove 133. It can be understood that the side of the lead-out portion 13 facing away from the body 11 is provided with the wire groove 133, and the provision of the wire groove 133 will increase the gap between the lead-out portion 13 and the cover plate 3. By providing the stop protrusion 32 on the side of the cover plate 3 facing the lead-out portion 13, the gap between the lead-out portion 13 and the cover plate 3 can be reduced, and the stop protrusion 32 can stop the power cord located in the wire groove 133, so as to prevent the power cord from falling out of the wire groove 133, and further improve the limiting effect of the wire groove 133 on the power cord. For example, in conjunction with the reference attachment Figure 2 and attached Figure 4 As shown, a positioning protrusion 134 is provided on the side of the lead-out portion 13 facing away from the main body 11, and a wire groove 133 is provided on the positioning protrusion 134. The stop protrusion 32 abuts against the portion of the positioning protrusion 134 where the wire groove 133 is not provided, and is spaced from the inner bottom wall of the wire groove 133 to ensure space for arranging the power cord.
[0055] In a further embodiment of the present invention, refer to the attached Figure 2 As shown, the lead pins 2 are arranged in a plurality of intervals along the circumferential direction of the body 11, and the wire grooves 133 are a plurality of one-to-one corresponding to the plurality of lead pins 2, which can separate and limit the plurality of sub-wires of the power line, thereby ensuring the correct wiring of the plurality of sub-wires.Figure 2 As shown, there are three lead pins 2 arranged at intervals in the circumferential direction of the main body 11, which are respectively electrically connected to the U wire, V wire, and W wire of the power supply line. There are three wire grooves 133 corresponding to the three lead pins 2 one by one, which can be used to place the U wire, V wire, and W wire of the power supply line respectively, so as to arrange the U wire, V wire, and W wire at intervals and limit them respectively to ensure the correct wiring of the power supply line.
[0056] It should be noted that concentrating the power supply line on the lead wire part 13 can reduce the length of the power supply line, improve the convenience of operation, reduce the usage amount of the lead wire part 13, and thus reduce the production and processing cost of the motor 100.
[0057] In a further embodiment of the present utility model, refer to the attached Figure 2 and the attached Figure 4 As shown, a water-blocking boss 135 is provided on the side of the lead wire part 13 facing away from the main body 11. The water-blocking boss 135 extends along the width direction of the opening 132 (refer to the c direction shown in the attached Figure 2 figure) and is spaced from the opening 132 in the radial direction of the main body 11, which can reduce the probability of water, dust, or other impurities entering the lead wire part 13 from the opening 132, play a protective role for the motor 100, improve the reliability and stability of the motor 100, and thus avoid affecting the effectiveness of the lead pins 2.
[0058] In a specific example, as Figure 4 shown, the stop protrusion 32 is located on the side of the water-blocking boss 135 facing away from the axis of the main body 11. It can be understood that the power supply line extends from the lead pin 2 to the opening 132. First, due to the existence of the water-blocking boss 135, the part of the power supply line located in the wire groove 133 is bent 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 jointly fix the power supply line. Then, due to the existence of the stop protrusion 32, the part of the power supply line located in the wire groove 133 is bent 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 jointly fix the power supply line. By bending the power supply line multiple times, a labyrinth structure can be formed, improving the fixing effect on the power supply line and ensuring the protective effect of the cover plate 3 and the lead wire part 13 on the power supply line and the lead pins 2.
[0059] In some embodiments of the present utility model, refer to the attached Figure 1 and the attached Figure 2As shown, the plastic-coated housing 1 further includes mounting ears 14. The mounting ears 14 are provided on the outer peripheral wall of the body 11 and are multiple and spaced along the circumferential direction of the body 11. This can facilitate the fixing and installation of the motor 100. The setting of multiple mounting ears 14 can form multiple mounting positions in the circumferential direction of the body 11, enabling the stator assembly 200 provided with the plastic-coated housing 1 to be fixedly installed at multiple locations in the circumferential direction of the body 11, thereby enhancing the connection stability between the stator assembly 200 and the connected part. At the same time, the force between the plastic-coated housing 1 and the connected part can be dispersed to multiple mounting ears 14, thus reducing the stress generated by each mounting ear 14, reducing 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 present utility model, referring to the attached Figure 2 As shown, the lead wire part 13 is provided between two adjacent mounting ears 14 among the multiple mounting ears 14, which can provide an outlet space for the power supply wire led out in the radial direction of the body 11, facilitating the leading out of the power supply wire.
[0061] In some embodiments of the present utility model, referring to the attached Figure 1 As shown, the plastic-coated housing 1 is an integral part and can be integrally processed by processes such as injection molding. This can reduce the production process, thereby improving production efficiency. At the same time, it can also enhance the connection strength between the body 11, the mating part 12, and the lead wire part 13, thereby enhancing the overall structural stability and reliability of the plastic-coated housing 1.
[0062] In some embodiments of the present utility model, the power supply wire is welded to the lead-out pin 2. After heating and melting a low-melting-point metal solder (usually a tin-based alloy), it penetrates and fills the gap at the connection of the metal parts to achieve the connection. It can form a firm welded connection through the melting of the solder and the wetting and diffusion on the metal surface. The equipment is simple, the operation is convenient, and it has good manufacturability, which can ensure the connection reliability between the power supply wire and the lead-out pin 2.
[0063] In other embodiments of the present utility model, the power supply wire and the lead-out pin 2 are connected through a mating terminal. The mating terminal has a compact structure, is convenient for installation and disassembly, can save space, and ensures the firmness and reliability between the power supply wire 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 through a mating terminal to ensure the connection reliability between the lead-out pin 2 and the winding wire of the stator assembly 200 and ensure manufacturability.
[0065] The present utility model also proposes an air conditioner with the motor 100 having the above embodiments.
[0066] Among them, the air conditioner includes an indoor unit and an outdoor unit. The above-mentioned motor 100 can be the motor 100 that drives the fan to rotate in the outdoor unit of the air conditioner, or the motor 100 that drives the impeller to rotate in the indoor unit of the air conditioner. Since the motor 100 adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated one by one here.
[0067] According to the air conditioner of the embodiment of the present invention, by providing the above-mentioned motor 100, and by making the lead wire portion 13 located radially outside the fitting portion 12, the power supply line is connected to the winding wire of the stator assembly 4 through the lead pin 2, so that the external placement of the power supply line can be realized. On the one hand, it realizes the isolation of the power supply line from the cavity defined by the body 11, reduces the risk of the power supply line rubbing against the rotor assembly 5, and at the same time avoids the additional designs such as sleeving heat shrink tubes on the power supply line or designing wire blocking posts on the plastic housing in the prior art, reducing the production and processing cost of the plastic housing 1; on the other hand, it can avoid the solder flying everywhere when connecting the power supply line and entering the cavity defined by the body 11, avoiding problems such as blockage or the need for additional cleaning of the solder, thereby improving the reliability and stability of the motor 100 and ensuring the normal operation of the motor 100.
