Description

Technical Field

[0001] The utility model relates to the technical field of slip rings, in particular to a slip ring structure and a motor. Background Art

[0002] With the development of modern science and technology, people are increasingly demanding low noise and long lifespan in electronic motors. At the same time, the demand for electronic products is also decreasing. If motors continue to use traditional commutators, the motor lifespan and noise levels will not meet current requirements. While brushless motors can meet these requirements in terms of lifespan and noise, the cost is too high. This has forced motor manufacturers to develop new commutation components, such as slip rings. Slip rings are also called conductive rings, slip rings, collector rings, and collector rings. They can be used in any electromechanical system that requires continuous rotation while also transmitting power and signals from a fixed position to a rotating position. Slip rings can improve system performance, simplify system structure, and prevent wire twisting during rotation.

[0003] Currently, common collector rings typically include multiple copper sheets arranged at intervals along the circumference, multiple leads, and a plastic body; a gap forms an insulating slot between adjacent copper sheets; multiple leads are welded to the multiple copper sheets in a one-to-one correspondence; the plastic body is formed on the inner side of the copper sheet through extrusion to fix the copper sheets together; the plastic body is connected as a whole but does not fill the aforementioned insulating slot. Therefore, during commutation, the carbon brush will pass through the insulating slot when it reaches the other copper sheet from one collector ring copper sheet. The carbon brush will deform into the insulating slot and then collide with the edge of the copper sheet, generating commutation sparks and loud noise, resulting in a short service life. Therefore, there is an urgent need for a collector ring that can meet customers' low cost requirements, low noise, and high service life requirements. Utility Model Content

[0004] In view of this, the utility model provides a slip ring structure and a motor to solve the problem of lack of a slip ring that can meet customers' requirements of low cost, low noise and long life.

[0005] In the first aspect, the utility model provides a collector ring structure, including a collector ring body, the collector ring body including a plurality of copper rings arranged in sequence along the axial direction, the inner side of each copper ring is integrally stamped with a lead, and the plurality of leads are arranged circumferentially at intervals; one end of the lead extends to the outside of the collector ring body and is folded outward to form a horizontal portion, the horizontal portion is arranged perpendicular to the axial direction, the plurality of horizontal portions are located on the same horizontal plane, and the length dimension of the horizontal portion is greater than the axial dimension of the collector ring body.

[0006] According to a slip ring structure of the utility model, there are at least the following beneficial effects:

[0007] A lead is integrally stamped on each copper ring, and the outer surface of the copper ring that is in direct contact with the carbon brush is a continuous smooth surface without grooves. When the motor equipped with the present collector ring structure changes direction during operation, the carbon brush will not collide with the copper ring due to deformation in the groove, and no voltage drop will be generated when the carbon brush contacts the outer surface of the copper ring, thereby avoiding commutation sparks caused by voltage shock that erode the outer surface of the copper ring, reducing wear on the outer surface of the copper ring to ensure service life, and avoiding generating loud noise, significantly improving the mechanical properties of the motor equipped with the present collector ring structure, and reducing the noise generated during operation of the motor equipped with the present collector ring structure; and because the lead and the copper ring are integrally formed by stamping, the processes of separately punching the lead and welding the lead to the copper ring can be omitted, the process is simpler, and the processing cost is lower. At the same time, one end of the collector ring body is extended through the lead and folded outward to form a horizontal portion. On the one hand, the multiple horizontal portions arranged at intervals along the circumference ensure that the two adjacent horizontal portions are separated from each other due to the gap space between adjacent horizontal portions, thereby avoiding short circuits during use. On the other hand, the horizontal portions arranged perpendicular to the axial direction can meet the needs of winding more coils on the motor, so that the collector ring body with the same outer diameter can achieve greater power, thereby improving the power of the motor equipped with this collector ring structure; it can also save the process of processing the bent hook, further simplify the preparation process, and reduce processing costs.

[0008] In an optional embodiment, it further includes an insulating body with a central axis hole, the insulating body including a first insulating portion and a second insulating portion that are integrally arranged, the first insulating portion being arranged inside the slip ring body and used to fix the plurality of copper rings together; the second insulating portion being arranged outside the slip ring body and used to partially cover the plurality of horizontal portions, the projection of the slip ring body along the axial direction falling within the range of the second insulating portion.

[0009] In an optional embodiment, the lead includes a connecting portion, one end of the connecting portion along the axial direction is connected to the horizontal portion, and the other end of the connecting portion is folded outward to form a mounting portion, and the mounting portion is connected to the inner wall of the copper ring.

[0010] In an optional embodiment, a connecting platform is protruding from the inner wall of the copper ring, and the first insulating portion covers the connecting platform.

[0011] In an optional embodiment, the inner wall of each copper ring is provided with two rows of connecting platform assemblies spaced apart along the axial direction, and each row of the connecting platform assemblies includes a plurality of the connecting platforms arranged at intervals along the circumferential direction; the connecting platform located relatively above in the axial direction in each copper ring is set as the first connecting platform, and the first connecting platform extends from the outer side to the inner side of the copper ring, and the first connecting platform is arranged to be tilted downward.

[0012] In an optional embodiment, the connecting platform located relatively below in the axial direction inside each copper ring is configured as a second connecting platform, the second connecting platform extends from the outer side to the inner side of the copper ring, and the second connecting platform is configured to be tilted upward.

[0013] In an optional embodiment, the insulating body is configured as a bakelite body.

[0015] In an optional embodiment, three copper rings are provided.

[0016] In a second aspect, the present invention further provides a motor, comprising the slip ring structure provided in the first aspect.

[0017] Because the motor includes a slip ring structure, it has the same beneficial effects as the slip ring structure and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0027] In the description of this embodiment, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this embodiment and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this embodiment. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this embodiment, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this embodiment based on specific circumstances.

[0029] There are two common types of collector rings in the related art. One type of collector ring includes multiple copper sheets, multiple leads, and a plastic body arranged at intervals along the circumference; there is a gap between two adjacent copper sheets to form an insulating groove; multiple leads are welded to the multiple copper sheets one by one; the plastic body is formed on the inner side of the copper sheet by extrusion molding to fix the copper sheets together; the plastic body is connected as a whole but does not fill the aforementioned insulating groove. Therefore, during commutation, the carbon brush will pass through the insulating groove in the process of reaching from one copper sheet of the collector ring to another copper sheet. The carbon brush will deform into the insulating groove, and then collide with the edge of the copper sheet, generating commutation sparks and loud noise, and a short service life. Another type of collector ring includes two copper rings arranged vertically at intervals, a long lead, a short lead, and a plastic body; the plastic body is arranged on the inner side of the copper ring to fix the two copper rings together; an insulating ring is provided between the two copper rings to insulate and isolate the two copper rings; however, each copper ring in this type of collector ring is formed by turning a copper tube, which has low processing efficiency and low yield. In addition, the long lead and the short lead are respectively punched out of copper sheets, and the punched long lead and the short lead are respectively welded to the two copper rings, which further increases the processing steps of the collector ring, reduces the production efficiency, and increases the processing cost. It is impossible to simultaneously meet the customer's low-cost requirements and low-noise and high-life requirements for the motor. In order to solve the above technical defects, a collector ring structure and a motor according to an embodiment of the utility model are provided.

[0030] The following combination Figures 1 to 4 , describing the embodiments of the present utility model.

[0031] According to the first aspect of the embodiment of the present utility model, a collector ring structure is provided, including a collector ring body 100, the collector ring body 100 includes a plurality of copper rings 110 arranged in sequence along the axial direction, the inner side of each copper ring 110 is integrally stamped with a lead 120, and the plurality of leads 120 are arranged circumferentially; one end of the lead 120 extends to the outside of the collector ring body 100 and folds outward to form a horizontal portion 121, the horizontal portion 121 is arranged perpendicular to the axial direction, and the plurality of horizontal portions 121 are located on the same horizontal plane. It can be understood that the axial direction mentioned herein refers to Figure 1 The axial direction refers to the axial direction of the copper ring 110, and the horizontal plane refers to a plane perpendicular to the axial direction.

[0032] The collector ring structure of this embodiment is formed by integrally stamping a lead 120 on each copper ring 110. The outer surface of the copper ring 110 that directly contacts the carbon brush is a continuous smooth surface without a groove. When the motor equipped with the collector ring structure of this embodiment changes direction during operation, the carbon brush will not collide with the copper ring 110 due to deformation in the groove, and the contact between the carbon brush and the outer surface of the copper ring 110 will not generate a voltage drop, thereby avoiding the commutation spark caused by voltage shock to corrode the outer surface of the copper ring 110, so that the outer surface of the copper ring 110 has little wear to ensure the service life, and avoids generating loud noise, significantly improving the mechanical properties of the motor equipped with the collector ring structure of this embodiment, and reducing the noise generated during the operation of the motor equipped with the collector ring structure of this embodiment; and because the lead 120 and the copper ring 110 are integrally formed by stamping, the process of punching the lead 120 separately and welding the lead 120 to the copper ring 110 can be omitted, the process is simpler and the processing cost is lower. At the same time, one end of the collector ring body 100 is extended through the lead 120 and folded outward to form a horizontal portion 121. On the one hand, the multiple horizontal portions 121 arranged at intervals along the circumference ensure that the two adjacent horizontal portions 121 are separated from each other due to the gap space between adjacent ones, thereby avoiding short circuits during use. On the other hand, the horizontal portions 121 arranged perpendicular to the axial direction can meet the needs of winding more coils on the motor, so that the collector ring body 100 with the same outer diameter can achieve greater power, thereby improving the power of the motor equipped with the collector ring structure of this embodiment; it can also save the process of processing the bent hook, further simplify the preparation process, and reduce processing costs.

[0033] It should be noted that the length of the horizontal portion 121 is greater than the axial dimension of the collector ring body 100, and is 1.5 to 2 times the axial dimension of the collector ring body 100, so that only a lead 120 needs to be integrally stamped on the inner side of each copper ring 110 to meet the number of windings of the motor coil, so that a motor with a smaller outer diameter equipped with the collector ring structure of this embodiment can cope with a larger torque; and because only one lead 120 needs to be set on the inner side of each copper ring 110, the processing technology of the collector ring structure of this embodiment is shorter and longer than that of conventional collector rings, and the cost is relatively lower.

[0034] It should be noted that, because there is no insulating groove on the surface of the copper ring 110, there is no need to perform a milling process during the preparation process, so as to avoid burrs caused by milling, thereby avoiding the noise generated by burrs during the operation of the motor equipped with the collector ring structure of this embodiment, and reducing the noise generated during the operation of the motor equipped with the collector ring structure of this embodiment.

[0035] Specifically, three copper rings 110 are provided, so that the three horizontal portions 121 are arranged at intervals of 120° from each other along the circumferential direction, so as to better perform winding on the horizontal portions 121 .

[0036] like Figure 1 and Figure 4 As shown, in some embodiments, the slip ring structure further includes an insulating body 200 with a central axial hole 210. The insulating body 200 includes an integrally arranged first insulating portion 220 and a second insulating portion 230. The first insulating portion 220 is disposed inside the slip ring body 100 and is used to secure the plurality of copper rings 110 together. The second insulating portion 230 is disposed outside the slip ring body 100 and is used to partially cover the plurality of horizontal portions 121. The axial projection of the slip ring body 100 falls within the range of the second insulating portion 230. On the one hand, by partially covering the plurality of horizontal portions 121 with the second insulating portion 230 having an outer diameter larger than that of the slip ring body 100, the insulating body 200 can cover and secure as many of the horizontal portions 121 as possible without affecting the number of coils wound on the horizontal portions 121, thereby improving the stability of the horizontal portions 121. On the other hand, the plurality of copper rings 110 are fixed together by the first insulating portion 220, and the first insulating portion 220 partially fills the gap space between two adjacent copper rings 110, thereby insulating and isolating the two adjacent copper rings 110 along the axial direction, thereby achieving the functions of fixing the plurality of copper rings 110 and insulating and isolating the two adjacent copper rings 110 along the axial direction. There is no need to separately set an insulating ring between the two adjacent copper rings 110, thereby improving the processing efficiency of the collector ring structure of this embodiment and reducing the processing cost of the collector ring structure of this embodiment.

[0037] Specifically, the insulating body 200 is configured as a bakelite body. The insulating body 200 is made of bakelite and is arranged on the inner side of the slip ring body 100 in an extrusion molding manner, and extends to the outside of the slip ring body 100 to cover all horizontal parts 121. The strength of bakelite material is greater than that of plastic, so that cracking is not easy to occur when the insulating body 200 is interference fit with the rotor shaft through the central shaft hole 210.

[0038] like Figure 2 and Figure 3 As shown, in some embodiments, the lead 120 includes a connecting portion 122, one axial end of which is connected to the horizontal portion 121, and the other end of the connecting portion 122 is folded outward to form a mounting portion 123, which is connected to the inner wall of the copper ring 110. The transition connection of the mounting portion 123 increases the distance between the connecting portion 122 and the inner wall of the copper ring 110, which can reduce the risk of short circuit caused by contact between the lead 120 and the copper ring 110 and facilitate the integral stamping of the lead 120 and the copper ring 110.

[0039] Specifically, a connection platform is protruded from the inner wall of the copper ring 110, and the first insulating portion 220 covers the connection platform. The first insulating portion 220 covers the connection platform to further increase the fastening connection area between the copper ring 110 and the insulating body 200.

[0040] like Figure 3 As shown, specifically, the inner wall of each copper ring 110 is provided with two rows of connecting platform assemblies at intervals along the axial direction, and each row of the connecting platform assemblies includes a plurality of the connecting platforms arranged at intervals along the circumferential direction; the connecting platform located relatively above the axial direction in each copper ring 110 is provided as a first connecting platform 111, and the first connecting platform 111 extends from the outer side to the inner side of the copper ring 110, and the first connecting platform 111 is tilted downward; in the process of using bakelite as raw material and being provided on the inner side of the collector ring body 100 in an extrusion molding manner to fill the through hole of the collector ring body 100 to form the first insulating part 220, the inclined first connecting platform 111 facilitates the injection molding melt to flow in the through hole of the collector ring body 100, ensuring that the entire through hole of the collector ring body 100 is filled to form the first insulating part 220, and the inclined first connecting platform 111 increases the contact area with the first insulating part 220, thereby ensuring that all copper rings 110 are firmly fixed together.

[0041] like Figure 2 and Figure 3 As shown, specifically, the connecting platform located relatively below in the axial direction in each of the copper rings 110 is set as a second connecting platform 112, and the second connecting platform 112 extends from the outer side to the inner side of the copper ring 110, and the second connecting platform 112 is tilted upward; the tilted second connecting platform 112 facilitates the flow of the injection molded melt in the through hole of the collector ring body 100 and increases the contact area with the first insulating part 220.

[0042] like Figure 2 and Figure 3As shown, in some embodiments, an insulating member 130 is provided within the slip ring body 100 at least corresponding to the position of the lead 120 of the copper ring 110 located relatively below in the axial direction. A U-shaped groove 131 is provided on the inward side of the insulating member 130. The U-shaped groove 131 is used to receive the connecting portion 122. Because the multiple copper rings 110 are arranged in sequence along the axial direction, the length of the lead 120 integrally stamped and formed on the lower copper ring 110 is longer than the length of the lead 120 integrally stamped and formed on the upper copper ring 110. To prevent the longer lead 120 from causing significant displacement during the extrusion molding process to obtain the insulating body 200, thereby contacting adjacent leads 120 or copper rings 110 and causing a short circuit, this embodiment inserts the connecting portion 122 of the longer lead 120 into the corresponding U-shaped groove 131 for positioning, ensuring that the longer lead 120 is unlikely to displace relative to the U-shaped groove 131 and cause a short circuit during the extrusion molding process. It should be noted that the lead 120 integrally stamped and formed on the top copper ring 110 is shorter and less likely to be displaced and cause a short circuit. In order to simplify the processing technology, the lead 120 integrally stamped and formed on the inner wall of the top copper ring 110 does not need to be embedded in the U-shaped groove 131 of the insulating part.

[0043] The method for preparing the slip ring structure of this embodiment includes the following steps:

[0044] Stamping: The copper shell is stamped to form three copper rings 110 , and each copper ring 110 is integrally stamped to form a lead 120 , and the top end of each lead 120 is folded outward to form a horizontal portion 121 ;

[0045] Degreasing and cleaning: degreasing and cleaning the copper ring 110 and the lead wire 120;

[0046] Drying: Drying the cleaned copper ring 110 and lead wire 120;

[0047] Insulation molding: The insulation member 130 is injection molded based on the width and height of the connection portion 122 of the lead 120 , so that the height of the insulation member 130 is smaller than the height of the connection portion 122 , and the width of the U-shaped groove 131 is not less than the width of the connection portion 122 ;

[0048] Semi-finished product assembly: The insulating member 130 is sleeved on the connecting portion 122 of the corresponding lead 120, and the three copper rings 110 are fixed along the axial direction at a preset interval to form the slip ring body 100;

[0049] Extrusion molding: Extruding the insulating body 200 with the central axis hole 210 into the slip ring body 100 with bakelite as the raw material;

[0050] Heat treatment: The insulating body 200 is heat treated to fully cross-link the bakelite material to remove moisture, gas, etc., release stress, and better ensure dimensional stability and electrical performance;

[0051] Finishing: performing finish processing on the lead 120;

[0052] Inner hole withstand voltage test: The collect ring structure is subjected to withstand voltage test to confirm whether the lead wire 120 contacts the adjacent copper ring 110 after deformation during extrusion molding of the insulating body 200, so as to avoid short circuit during use;

[0053] Appearance inspection: Check the appearance of the slip ring structure for obvious defects;

[0054] Packaging and shipment: The collector ring structures that have passed the inner hole pressure inspection and the appearance inspection will be packaged and shipped.

[0055] Specifically, during the extrusion molding process, three feed ports arranged at equal intervals along the circumference are used to feed materials simultaneously, so as to better ensure the roundness of the extruded slip ring body 100 and better meet the dimensional stability.

[0056] According to a second aspect of the embodiment of the present utility model, a motor is further provided, comprising the slip ring structure provided in the first aspect of the embodiment of the present utility model. The collector ring structure of the motor of this embodiment is formed by integrally stamping a lead 120 on each copper ring 110. The outer surface of the copper ring 110 that is in direct contact with the carbon brush is a continuous smooth surface without a groove. When the motor of this embodiment changes direction during operation, the carbon brush will not collide with the copper ring 110 due to deformation in the groove, and the contact between the carbon brush and the outer surface of the copper ring 110 will not generate a voltage drop, thereby avoiding the commutation spark caused by voltage shock to corrode the outer surface of the copper ring 110, so that the outer surface of the copper ring 110 has little wear to ensure the service life, and avoids generating loud noise, significantly improving the mechanical properties of the motor of this embodiment, and reducing the noise generated during the operation of the motor of this embodiment; and because the lead 120 and the copper ring 110 are integrally formed by stamping, the process of separately punching the lead 120 and welding the lead 120 to the copper ring 110 can be omitted in the process of preparing the collector ring structure of the motor of this embodiment, the process is simpler and the processing cost is lower. At the same time, one end of the collector ring body 100 is extended through the lead 120 and folded outward to form a horizontal portion 121. On the one hand, the multiple horizontal portions 121 arranged at intervals along the circumference ensure that the two adjacent horizontal portions 121 are separated from each other due to the gap space between adjacent ones, thereby avoiding short circuits during use. On the other hand, the horizontal portions 121 arranged perpendicular to the axial direction can meet the needs of winding more coils on the motor, so that the collector ring body 100 with the same outer diameter can achieve greater power, thereby improving the power of the motor of this embodiment; it can also save the process of processing the bent hook, further simplify the preparation process, and reduce processing costs.

[0057] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present invention.
