[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0043] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0044] In the related technology, the motor shaft and the motor housing are connected through a conductive plate to reduce the shaft voltage on the motor shaft and protect the motor bearings. However, under harsh working conditions such as rain / immersion tests, the waterproof performance of the conductive plate and the outlet of the motor housing is weak, and water may enter the motor, causing the motor performance to deteriorate or even fail to work normally.

[0045] To this end, the utility model proposes a wire outlet nozzle, which is used for a motor. This solution aims to achieve the goal of low cost and high waterproofness without changing the original structure and components, so as to meet the needs of the market and users.

[0046] Reference Figure 1 In one embodiment of the utility model, the motor 10 is specifically a brushless motor 10, which is used in household appliances such as air conditioners. It has the advantages of high reliability, no commutation sparks, and low mechanical noise. The motor 10 is described below with a specific example.

[0047] The motor 10 includes a stator assembly 20, a bottom cover 40, a conducting plate 50 and a wire outlet nozzle 60. The stator assembly 20 has an opening 31, and the edge of the opening 31 is provided with a wire clamp opening 32 and a mounting stopper 33; Figure 1 The brushless motor 10 includes a stator assembly 20, a rotor assembly, two bearings, etc. The stator assembly 20 includes a housing and a stator assembly, which are formed into a plastic-encapsulated housing 30 by injection molding. An installation space is formed inside the plastic-encapsulated housing 30, and the installation space is used to accommodate the rotor assembly. One end of the plastic-encapsulated housing 30 along the axial direction of the stator assembly is opened to form an opening 31, and the opening 31 is connected to the installation space. During assembly, the stator assembly is firstly injection molded to form the plastic-encapsulated housing 30, and then the rotor assembly and other components are assembled into the installation space through the opening 31.

[0048] Reference Figures 2 to 4 The top of the plastic-encapsulated housing 30 has an upper cover, and the bottom cover 40 covers the opening 31. The bearings are arranged on the upper cover and the bottom cover 40 to support the rotating shaft so that the rotor assembly can rotate in the stator assembly. When the brushless motor 10 is powered on, the rotor assembly rotates relative to the stator assembly under the excitation, and the rotor assembly outputs the rotational motion.

[0049] The application environment of the motor 10 is becoming more and more extensive. During the design process of the motor 10, more attention should be paid to the reliability of the motor 10 in harsh environments, especially in rainy conditions, where water is easily intruded at the outlet of the wires of the motor 10, causing the performance of the motor 10 to deteriorate or even fail to work properly. The outlet nozzle 60 of the traditional motor 10 is made of plastic material, and the waterproof ability at the line clamp 32 is weak. At present, there are two solutions to improve the waterproof ability of the outlet nozzle 60 of the motor 10: First, the power cord and the outlet nozzle 60 are injection molded together with the stator assembly. This solution has low efficiency and a high defect rate of the stator injection molded power cord; second, the outlet nozzle 60 uses glue. This solution takes a long time for the glue to solidify, the glue cost is high, and the environmental protection is not good.

[0050] Reference Figures 1 to 4 In this solution, the bottom cover 40 and the stator assembly together cover the opening 31; the conduction plate 50 connects the bottom cover 40 and the stator assembly respectively, and the conduction plate 50 includes a flanged hook 51, and the flanged hook 51 is arranged at the installation stop 33; the outlet nozzle 60 includes an outlet body 61 and a connecting portion 62 connected to the outlet body 61, and the outlet body 61 is sealed at the wire clamp opening 32, and the connecting portion 62 extends from the outlet body 61 to the installation stop 33, and a part of the connecting portion 62 is arranged in the installation stop 33 and seals the gap between the installation stop 33 and the flanged hook 51. Through the outlet nozzle 60, the wire clamp body of the lead frame is sealed at the wire clamp opening 32, and the wire clamp body is an elastic member made of elastic material, such as rubber, silicone, etc. The wire clamp body can clamp the wires to fix them, for example, the wire clamp body can be separated into two parts, the upper and lower parts, to clamp the wires, or the wires can be passed through the wire clamp body to position the entire wiring harness. The wire clamp body is installed in the wire clamp opening 32, and the inner wall of the wire clamp opening 32 is used to squeeze the wire clamp body, so that the wire clamp body is deformed and fits tightly with the inner wall of the wire clamp opening 32 to form a seal, thereby effectively sealing the wire clamp body and the plastic shell 30. In this way, the wire clamp body can not only fix the wire harness, but also play a sealing role. This solution optimizes the assembly structure of the wire clamp body and the wire clamp opening 32, effectively improving the sealing of the motor 10, reducing the phenomenon of water ingress into the motor 10, and improving the operating reliability of the motor 10.

[0051] Combination Figure 8 and Fig. 9Furthermore, in order to avoid excessive shaft voltage, which may cause obvious electro-corrosion grooves between the inner and outer rings of the motor 10 bearing, thereby generating abnormal order noise, and in severe cases, causing damage to the motor 10 bearing. The conducting plate 50 is respectively connected to the bottom cover 40 and the stator assembly, and the conducting plate 50 includes a flanged hook 51, and the flanged hook 51 is arranged at the installation stop 33. Under relatively harsh working conditions, the gap between the installation stop 33 and the flanged hook 51 will affect the waterproof performance of the motor 10. For this reason, in this solution, the outlet body 61 is also provided with a connecting portion 62, and the outlet body 61 is sealed at the wire clamp opening 32, and the connecting portion 62 extends from the outlet body 61 to the installation stop 33. Part of the connecting portion 62 is arranged in the installation stop 33 and seals the gap between the installation stop 33 and the flanged hook 51. Compared with redesigning the mold or using methods such as dispensing, which have the problems of high cost and low efficiency, this solution does not change the original structure and components, and achieves the goal of low cost and high waterproofness, thereby meeting the needs of the market and users.

[0052] Reference Figures 5 to 7 Specifically, the connecting portion 62 includes an extension section 621 and an abutment portion 622 provided on the extension section 621, the extension section 621 is connected to the outlet body 61, the abutment portion 622 protrudes from the extension section 621 toward the installation stop 33, and the abutment portion 622 cooperates with the installation stop 33 to seal.

[0053] Compared with the separate sealing parts, which are difficult to process and easy to lose, the connection part 62 and the outlet body 61 are arranged together, which reduces the degree of processing and is less likely to be lost.

[0054] In one embodiment, the connecting portion 62 and the outlet body 61 are integrally formed, such as by injection molding.

[0055] In one embodiment, the abutting portion 622 is configured as two convex ribs 623 arranged in parallel with the extension section 621 , and the two convex ribs 623 abut against and seal against the inner wall of the mounting stop 33 .

[0056] In one embodiment, the abutting portion 622 is configured as a solid protrusion adapted to the mounting stop 33 .

[0057] Reference Figure 7 In one embodiment, the rib 623 is limited by the spacing between the mounting stop 33 and the conducting plate 50 after being matched, and needs to meet a certain thickness requirement, so as to better seal the gap between the mounting stop 33 and the flange hook 51. Specifically, the height of the rib 623 protruding toward the mounting stop 33 is d, 0.5mm≤d≤0.8mm.

[0058] If the height d of the rib 623 protruding toward the mounting stop 33 is less than 0.5 mm, the sealing effect may be poor, so that the gap between the mounting stop 33 and the flange hook 51 cannot be effectively sealed. At the same time, if d is too large, exceeding 0.8 mm, the height of the rib 623 may be too large, thereby affecting the stability and reliability of the entire structure. Therefore, the height d of the rib 623 needs to meet the limit of 0.5 mm ≤ d ≤ 0.8 mm to ensure that the rib 623 can effectively seal the gap between the mounting stop 33 and the flange hook 51, while ensuring the stability and reliability of the entire structure.

[0059] Reference Figure 6 and Fig. 9 In one embodiment, the width of the conducting plate 50 is T, and the distance between the two ribs 623 is M, where M≤T-0.1, in mm. Controlling the width of the conducting plate 50 within the above range can ensure the conduction effect.

[0060] The plastic-encapsulated motor 10 is a motor 10 in which the stator core, winding, etc. are encapsulated as a whole with engineering plastics using plastic encapsulation technology, and the traditional motor 10 stator insulation treatment process and the metal casing of the ordinary motor 10 can be eliminated. This micro-special motor 10 is used in household appliances such as vacuum cleaners, range hoods, air conditioners, washing machines, and instrument fans. The development and production of the plastic-encapsulated motor 10 are increasingly valued at home and abroad, and it has a promising future because of a series of advantages that the metal shell motor 10 does not have; since the plastic-encapsulated motor 10 adopts a plastic-encapsulated structure, the surface after plastic encapsulation is a non-magnetic conductive material, and the permanent magnet rotor cuts the stator after running, generating induced voltages of different frequencies. These voltages have no loop in the non-magnetic conductive structure and cannot flow into the earth. More uneven magnetic fields appear in the magnetic circuit, and they are constantly cut alternately in the magnetic circuit, generating voltages between the two ends of the motor shaft or between the rotating shaft and the bearing seat, that is, shaft voltage. The main reason for the shaft voltage is the imbalance of the magnetic circuit surrounding the motor shaft. This unbalanced magnetic flux cuts the rotating shaft, and the shaft voltage is induced at both ends of the shaft. The shaft voltage passing through the rotating shaft not only affects the service life of the bearing, but also affects the noise index of the motor 10.

[0061] The conducting plate 50 is made of conductive metal material and is a long strip-shaped plate. The conducting plate 50 is arranged on the outer wall of the plastic-sealed shell 30. The upper end of the conducting plate 50 extends along the outer wall of the plastic-sealed shell 30 to the end face position at the opening 31. The end of the conducting plate 50 is fixed on the end face and does not enter the inside of the plastic-sealed shell 30, so as to avoid the conducting plate 50 passing through the side wall of the plastic-sealed shell 30 and affecting the sealing between the upper cover and the plastic-sealed shell 30. In addition, the lower end of the conducting plate 50 extends along the outer wall of the plastic-sealed shell 30 and is connected to the bottom cover 40. The lower end of the conducting plate 50 does not enter the inside of the plastic-sealed shell 30. Moreover, the upper cover and the plastic-sealed shell 30 are integrally injection molded, and the structure is stable and reliable, and has high sealing performance. The conducting plate 50 can be electrically connected to the upper cover in a variety of ways, such as by riveting, crimping, etc., which are not specifically limited.

[0062] The conduction plate 50 is respectively connected to the bottom cover 40 and the stator assembly 20, and the conduction plate 50 is provided with a flanged hook 51, and the flanged hook 51 is engaged with the installation stop 33; one end of the conduction plate 50 is provided with a flanged hook 51, and the other end is provided with a fixing portion. During the specific installation, the fixing portion is connected to the end cover of the bearing, that is, the upper cover, and the flanged hook 51 at the other end is engaged with the installation stop 33, so as to prevent the conduction plate 50 from rotating during the installation process and avoid displacement of the conduction plate 50 during subsequent use.

[0063] Reference Figure 3 , Figure 6 and Fig. 9 In one embodiment, the width of the rib 623 is L, the groove width of the mounting stop 33 is N, L≥(N-T+0.1) / 2, unit: mm.

[0064] Reference Figure 7 In order to ensure that the extension section 621 has a certain strength, in one embodiment, the thickness of the extension section 621 is D, 1.0mm≤D≤1.2mm, the extension section 621 is located at the edge of the opening 31, and the bottom cover 40 covers the opening 31. When the thickness of the extension section 621 is less than 1mm, the extension section 621 is prone to breakage, thereby affecting the sealing performance of the container. When the thickness of the extension section 621 is greater than 1mm, the bottom cover 40 may not be able to completely cover the opening 31, which will also increase the cost.

[0065] Specifically, the material of the outlet nozzle 60 is silicone or rubber, and the hardness range is HS47-HS53. The outlet nozzle 60 needs to have a certain hardness to ensure that it can firmly fix the wire and prevent the wire from loosening or falling off. At the same time, the hardness of the outlet nozzle 60 also needs to be moderate. Too hard may cause damage to the wire, and too soft may not effectively fix the wire.

[0066] Specifically, by connecting the upper cover of the plastic package shell 30 to the bottom cover 40 through the conductive plate 50, the equivalent capacitance of the motor 10 can be reduced, thereby reducing the shaft voltage, achieving the purpose of reducing electrical corrosion, which is beneficial to increasing the service life of the bearing and making the motor 10 run stably and reliably.

[0067] The outlet nozzle 60 is elastic and has a certain hardness to ensure that the outlet nozzle 60 will deform. The hardness can reflect the compressive resistance of the outlet nozzle 60. The smaller the hardness, the easier it is for the outlet nozzle 60 to deform. On the contrary, the greater the hardness, the less likely it is for the outlet nozzle 60 to deform. Too small or too large hardness will affect the sealing performance between the outlet nozzle 60 and the plastic package shell 30. When the outlet nozzle 60 is deformed, the side wall of the outlet nozzle 60 and the side wall of the wire clamp opening 32 will form an interference fit.

[0068] In one embodiment, the outer periphery of the stator assembly 20 is provided with a mounting groove 34, the mounting groove 34 extends along the axial direction of the stator assembly 20 to communicate with the mounting stop 33, and the conducting plate 50 is embedded in the mounting groove 34. The conducting plate 50 is embedded in the mounting groove 34 to ensure the quality of the overall appearance.

[0069] In one embodiment, a contact portion 52 is disposed on a side of the conductive plate 50 facing the bottom cover 40 , and the contact portion 52 abuts against an inner wall of the bottom cover 40 .

[0070] Specifically, the contact portion 52 is an elastic folded edge formed by the conductive plate 50 itself toward the inner wall of the bottom cover 40, so that after the bottom cover 40 covers the plastic shell 30, the folded edge is pressed back close to the conductive plate 50. In this process, the bottom cover 40 and the plastic shell 30 can be tightly connected, and after the bottom cover 40 is closed, the folded edge will be blocked by the bottom cover 40, or at least partially blocked, so that it will not appear abrupt; it also ensures that the conductive plate 50 can be connected to the shell 30, thereby reducing the shaft voltage.

[0071] In one embodiment, the conductive plate 50 is directly connected to the bottom cover 40 .

[0072] Specifically, in order to improve the sealing performance of the outlet nozzle 60, the problem of water easily entering the outlet position of the motor 10 under harsh working conditions is effectively solved, the operating reliability of the motor 10 is improved, and the operation of the electrical equipment is made more stable. The wire outlet body 61 includes a main body 611, a retaining edge 612 arranged on the outer side of the main body 611 and a limiting edge 613 arranged on the inner side of the main body 611; the limiting edge 613 is flush with the top of the main body 611 and extends out of the main body 611 on the circumferential side; the retaining edge 612 extends out of the main body 611 corresponding to the limiting edge 613, and the retaining edge 612 and the limiting edge 613 form a limiting groove 614 at the bottom and side of the main body 611, and the limiting groove 614 cooperates with the inner wall of the wire clamp opening 32, the main body 611 is located in the wire clamp opening 32, and the limiting edge 613 and the retaining edge 612 are located on the inner and outer sides of the wire clamp opening 32.

[0073] During installation, a limiting groove 614 is formed on the inner side of the wire clamp opening 32 of the plastic package shell 30, and the limiting edge 613 is embedded in the limiting groove 614, while the retaining edge 612 contacts the outer side of the wire clamp opening 32, forming a matching structure with the inner wall of the wire clamp opening 32 as a slide rail, and the limiting edge 613 and the retaining edge 612 as a slide groove. The wire clamp body can be inserted into the wire clamp opening 32, and the main body 611 is located in the wire clamp opening 32. Because the bottoms of the retaining edge 612 and the limiting edge 613 exceed the main body 611, on the outside, part of the retaining edge 612 blocks the wire clamp opening 32, that is, the retaining edge 612 is exposed on the outside of the wire clamp opening 32. In this way, after the bottom cover 40 covers the opening 31, it will squeeze the main body 611, so that the main body 611 is deformed and the inner wall of the wire clamp opening 32 is interference fit to achieve sealing. In addition, the edge of the bottom cover 40 will press the edge of the retaining edge 612 to ensure the sealing of the outlet.

[0074] Specifically, the outlet nozzle 60 further includes an outlet nozzle 63 having a wire hole 631 passing through the outlet body 61 . The outlet nozzle 63 extends in a direction away from the outlet body 61 . When in use, the outlet nozzle 63 can be tightly sealed with a band.

[0075] The extension section 621 extends from the top of the main body 611 to one side, and the abutment portion 622 faces the edge of the opening 31. In this way, after the main body 611 is embedded in the line clamp 32, the abutment portion 622 on the extension section 621 can be positioned accordingly, and then the abutment portion 622 is embedded in the installation stop 33 through a tool. After the abutment portion 622 is deformed, it will seal the installation stop 33, so that the gap between the flange hook 51 and the installation stop 33 will be sealed by the abutment portion 622, effectively solving the problem of water ingress at the outlet position of the motor 10 under harsh working conditions, thereby improving the operating reliability of the motor 10 and making the operation of the electrical equipment more stable. Compared with re-molding or other sealing methods, this solution does not change the original structure and components, can achieve the goal of low cost and high waterproofness, and meet the needs of the market and users.
