Description

Technical Field

[0001] The present invention relates to the field of motors, and in particular to a motor and a method for assembling a motor. Background Art

[0002] In the prior art, when supplying power to a motor, a bus bar is sometimes required to electrically connect the internal components of the motor to an external power source. For example, one end of the bus bar is connected to a connection terminal of the internal component of the motor, and the other end of the bus bar is connected to the external power source.

[0003] It should be noted that the above technical background is merely provided to provide a clear and complete description of the technical solutions of the present invention and to facilitate understanding by those skilled in the art. Simply because these solutions are described in the technical background section of the present invention, it should not be assumed that the above technical solutions are well known to those skilled in the art. Summary of the Invention

[0004] The inventors discovered that when the busbar has a multi-section bending structure, the busbar can be positioned using the abutment surfaces in the motor. For example, the first abutment surface is used to position the first bent portion of the busbar in the axial direction, and the second abutment surface is used to position the second bent portion of the busbar in the axial direction. Since, during the manufacturing process of the motor, it cannot be guaranteed that the distance between the first abutment surface and the second abutment surface is completely equal to the distance between the first bent portion and the second bent portion of the busbar, when the first bent portion of the busbar is abutted against the first abutment surface, it cannot be guaranteed that the second bent portion of the busbar is reliably abutted against the second abutment surface, that is, the busbar cannot be reliably supported. As a result, when the other end of the busbar is connected to an external power source, the busbar is prone to axial movement.

[0005] In order to solve at least one of the above problems or other similar problems, embodiments of the present invention provide a motor and a method for assembling a motor, which can reliably support a bus bar.

[0006] According to a first aspect of an embodiment of the present invention, a motor is provided, wherein the motor includes: a bus bar, which includes a first portion of the bus bar and a second portion of the bus bar, and the first portion of the bus bar and the second portion of the bus bar are separately molded; a first supporting component, which has a first supporting surface, and the first supporting surface supports the first abutment portion of the first portion of the bus bar toward the first direction; and a second supporting component, which has a second supporting surface, and the second supporting surface supports the second abutment portion of the second portion of the bus bar toward the first direction, and the second supporting surface is located on one side of the first supporting surface in the first direction; wherein the first portion of the bus bar also includes a first connecting portion, and the second portion of the bus bar also includes a second connecting portion, the first connecting portion is electrically connected to the second connecting portion, and the distance between the first connecting portion and the second connecting portion in the first direction is variable.

[0007] According to a second aspect of an embodiment of the present invention, a method for assembling a motor is provided, wherein the motor includes a busbar, a first supporting member and a second supporting member, wherein the busbar includes a first portion busbar and a second portion busbar that are separately molded, wherein the method includes: abutting the first abutting portion of the first portion busbar against the first supporting surface of the first supporting member so that the first supporting surface supports the first abutting portion toward the first direction; and abutting the second abutting portion of the second portion busbar against the second supporting surface of the second supporting member so that the second supporting surface supports the second abutting portion toward the first direction, wherein the first connecting portion of the first portion busbar is electrically connected to the second connecting portion of the second portion busbar, and the distance between the first connecting portion and the second connecting portion in the first direction is variable.

[0008] One of the beneficial effects of the embodiment of the present invention is that the busbar can be reliably supported and positioned by making the busbar a split-molded structure and making the distance between the first connecting portion of the first busbar portion and the second connecting portion of the second busbar portion variable in the first direction.

[0023] Example 1

[0024] Embodiment 1 of the present invention provides a motor, Figure 1 is a schematic diagram of the motor 1 according to embodiment 1 of the present invention, Figure 2 This is a partially enlarged schematic diagram of the motor 1 according to the first embodiment of the present invention, which shows Figure 1 The dotted box B corresponds to the range, Figure 3 is a cross-sectional view of the motor 1 according to embodiment 1 of the present invention, wherein: Figure 3 Shown along Figure 1 The cross-sectional view of the section line AA' in Figure 4 This is a partially enlarged cross-sectional view of the motor 1 according to the first embodiment of the present invention, showing Figure 3 The dotted box C corresponds to the range.

[0025] In at least one embodiment, Figure 1 and Figure 3 As shown, the motor 1 includes a bus bar 11, a first support member 12 ( Figure 3 shown) and the second supporting member 13 ( Figure 3 shown).

[0026] The bus bar 11 includes a first bus bar portion 111 and a second bus bar portion 112. The first bus bar portion 111 and the second bus bar portion 112 are formed separately.

[0027] The first supporting member 12 has a first supporting surface 121. The first supporting surface 121 faces a first direction (eg Figure 3 As shown in FIG. 1 , the first abutting portion 1111 supports the first portion of the bus bar 111 .

[0028] The second support member 13 has a second support surface 131. The second support surface 131 supports the second contact portion 1121 of the second partial bus bar 112 toward the first direction. The second support surface 131 is located on one side of the first support surface 121 in the first direction.

[0029] The first partial bus bar 111 further includes a first connection portion 1112 , and the second partial bus bar 112 further includes a second connection portion 1122 . The first connection portion 1112 is electrically connected to the second connection portion 1122 , and a distance between the first connection portion 1112 and the second connection portion 1122 in the first direction is variable.

[0030] According to the above embodiment, the busbar 11 is formed into a split structure and the distance between the first connection portion 1112 of the first partial busbar 111 and the second connection portion 1122 of the second partial busbar 112 in the first direction is variable, so that the busbar 11 can be reliably supported and positioned.

[0031] In at least one embodiment, the motor 1 can be any type of motor, and this application does not impose any specific limitation on this.

[0032] In at least one embodiment, the motor 1 may include more than one bus bar 11. For example, Figure 2 As shown, the motor 1 may include three bus bars 11 .

[0033] In at least one embodiment, the bus bar 11 may include two parts formed separately. Figure 3 As shown, the busbar 11 may include a first busbar portion 111 and a second busbar portion 112 formed separately. However, the present application is not limited thereto, and the busbar 11 may also include three or more separately formed portions, thereby enabling the busbar 11 to be applied to more scenarios.

[0034] In at least one embodiment, Figure 3 As shown, the second bus bar 112 may further include an inserting portion 1123, wherein the inserting portion 1123 is electrically connected to the power supply outside the motor 1 and is located on one side of the first direction of the second supporting surface 131 (eg, Figure 3 upper side shown).

[0035] In at least one embodiment, the insertion portion 1123 of the bus bar 11 can be any shape that can be electrically connected to an external power source. Figure 2 As shown, the inserting portion 1123 may be in a plate shape.

[0036] In at least one embodiment, Figure 3 As shown, the first abutting portion 1111 of the first portion of the busbar 111 can abut against the first supporting surface 121, and the first supporting surface 121 supports the first abutting portion 1111 in the first direction. For example, the first supporting surface 121 can be a surface perpendicular to the first direction, which can apply a supporting force in the first direction to the first abutting portion 1111. For another example, the first supporting surface 121 can also be a surface that forms a certain angle with the first direction. In other words, the supporting force applied by the first supporting surface 121 to the first abutting portion 1111 has a component in the first direction, thereby also supporting the first abutting portion 1111 in the first direction.

[0037] In at least one embodiment, Figure 3 As shown, the second abutting portion 1121 of the second busbar portion 112 can abut against the second supporting surface 131, which supports the second abutting portion 1121 in the first direction. For example, the second supporting surface 131 can be a surface perpendicular to the first direction, which can apply a supporting force in the first direction to the second abutting portion 1121. For another example, the second supporting surface 131 can also be a surface that forms a certain angle with the first direction. In other words, the supporting force applied by the second supporting surface 131 to the second abutting portion 1121 has a component in the first direction, thereby also supporting the second abutting portion 1121 in the first direction.

[0038] In at least one embodiment, the first supporting surface 121 may be parallel to the second supporting surface 131. However, the present application is not limited thereto, and the first supporting surface 121 may also be a surface that forms a certain angle with the second supporting surface 131. In this way, a supporting surface for supporting and positioning the busbar 11 can be more flexibly provided in the motor 1.

[0039] In at least one embodiment, Figure 3 As shown, the first connecting portion 1112 of the first partial bus bar 111 and the second connecting portion 1122 of the second partial bus bar 112 can be electrically connected between the first supporting surface 121 and the second supporting surface 131. Disposing the first connecting portion 1112 and the second connecting portion 1122 between the first supporting surface 121 and the second supporting surface 131 facilitates miniaturization of the motor 1, shortens the length of the first connecting portion 1112 and the second connecting portion 1122, and simplifies the manufacturing process of the bus bar 11.

[0040] However, the present application is not limited thereto, and the first connecting portion 1112 and the second connecting portion 1122 may also be on the side of the first supporting surface 121 opposite to the first direction (eg, Figure 3 Alternatively, the first connection portion 1112 and the second connection portion 1122 may also be electrically connected on one side of the first direction of the second support surface 131 (as shown in FIG. Figure 4 The upper side of the second supporting surface 131 shown is electrically connected.

[0041] In at least one embodiment, the first connection portion 1112 and the second connection portion 1122 can be electrically connected by abutting each other. The first connection portion 1112 and the second connection portion 1122 can abut in any direction. For example, Figure 3 As shown, the first connection portion 1112 and the second connection portion 1122 can abut against each other in a second direction perpendicular to the first direction; for example, the first connection portion 1112 and the second connection portion 1122 can abut against each other in the first direction; for example, the first connection portion 1112 and the second connection portion 1122 can abut against each other in a direction that has a certain angle with the first direction.

[0042] In at least one embodiment, the first connection portion 1112 and the second connection portion 1122 may be structures that undergo elastic deformation in the second direction. Figure 3 As shown, the first connection portion 1112 can overlap with the second connection portion 1122 in the second direction and be electrically connected in a manner of elastic deformation in the second direction.

[0043] In at least one embodiment, the first connection portion 1112 and the second connection portion 1122 may be structures that are elastically deformable in the first direction. For example, the length of the first connection portion 1112 in the first direction may be variable, for example, the first connection portion 1112 may include a first elastic component that is elastically deformable when subjected to an external force; or the length of the second connection portion 1122 in the first direction may be variable, for example, the second connection portion 1122 may include a second elastic component that is elastically deformable when subjected to an external force; or both the lengths of the first connection portion 1112 and the second connection portion 1122 in the first direction may be variable.

[0044] In at least one embodiment, the first connection portion 1112 and the second connection portion 1122 may also be structures that are elastically deformable in the first direction and the second direction.

[0045] In at least one embodiment, the distance between the first connection portion 1112 and the second connection portion 1122 in the first direction is variable, that is, the relative position of the first connection portion 1112 and the second connection portion 1122 in the first direction is variable. Figure 3As shown, when the first connection portion 1112 and the second connection portion 1122 abut against each other in the second direction, the length of the portion where the first connection portion 1112 and the second connection portion 1122 overlap can be varied. For another example, when the first connection portion 1112 and the second connection portion 1122 abut against each other in the first direction, at least one of the first connection portion 1112 and the second connection portion 1122 is compressed compared to a case where they are not abutting against each other.

[0046] Since the distance between the first connection portion 1112 and the second connection portion 1122 in the first direction is variable, the bus bar 11 can be reliably supported by the first support surface 121 and the second support surface 131 by adjusting the distance between the first connection portion 1112 and the second connection portion 1122 in the first direction. Therefore, when the insertion portion 1123 of the bus bar 11 is connected to an external power supply, the bus bar 11 can be prevented from moving in the first direction.

[0047] In at least one embodiment, Figure 4 As shown, the motor 1 may further include a fixing portion 14. The fixing portion 14 is at least partially located on the outer periphery of the first connecting portion 1112 and the second connecting portion 1122. The inner periphery of the fixing portion 14 abuts against the first connecting portion 1112 and / or the second connecting portion 1122. This allows the first connecting portion 1112 and the second connecting portion 1122 to be positioned, ensuring reliable electrical connection.

[0048] In at least one embodiment, the fixing portion 14 may be a resin holder. However, the present application is not limited thereto, and the fixing portion 14 may also be other components.

[0049] In at least one embodiment, Figure 4 As shown, the first contact portion 1111 of the first partial bus bar 111 can contact the first support surface 121 via the fixing portion 14 , and the second contact portion 1121 of the second partial bus bar 112 can contact the second support surface 131 via the fixing portion 14 .

[0050] In at least one embodiment, Figure 4 As shown, the fixing portion 14 may include a foot portion 141 supported on the first supporting surface 121, and the first abutting portion 1111 of the first portion of the bus bar 111 may abut against the first supporting portion 121 through the foot portion 141, for example, abutting against one axial side of the stator core 12' (such as Figure 4 In addition, the first connection portion 1112 and the second connection portion 1122 can be connected to one axial side of the foot portion 141, so that when the first connection portion 1112 and the second connection portion 1122 are connected, the foot portion 141 can reliably support them.

[0051] In at least one embodiment, the first direction may be a direction toward one axial side of the motor 1. However, the present application is not limited thereto, and the first direction may also be other directions. The structure of the motor 1 is described below using the example of the first direction being a direction toward one axial side of the motor 1.

[0052] In at least one embodiment, Figure 4 As shown, the first support member 12 is the stator core 12' of the motor 1, the first support surface 121 is the surface 121' on one axial side of the stator core, and the second support member 13 is the housing 13' of the motor 1, and the second support surface 131 is the surface 131' on one axial side of the housing. However, the present application is not limited to this, and the first support member 12 and the second support member 13 may also be other components of the motor 1. For example, the first support member 12 and the second support member 13 may both be the housing of the motor 1. By configuring the housing of the motor 1 as a multi-step structure, the stepped structure of the housing is utilized to abut the first and second bus bars 111, 112, respectively.

[0053] The structure of the motor 1 is described below by taking as an example a case where the first supporting component 12 is the stator core 12' of the motor 1, the first supporting surface 121 is the surface 121' on the axial side of the stator core, the second supporting component 13 is the housing 13' of the motor 1, and the second supporting surface 131 is the surface 131' on the axial side of the housing.

[0054] In at least one embodiment, the first contact portion 1111 of the first busbar portion 111 can be electrically connected to the coil winding of the stator core 12 ′, thereby enabling power to be supplied to the stator of the motor 1 through the busbar 11 .

[0055] In at least one embodiment, the second abutting portion 1121 of the second bus bar portion 112 may abut against the housing 13 ′ through the fixing portion 14 , thereby preventing the second bus bar portion 112 from being electrically connected to the housing 13 ′.

[0056] In at least one embodiment, the first abutting portion 1111 extends from an end D on the other axial side of the first connecting portion 1112 toward a direction perpendicular to the axial direction, specifically, toward the radial inner side.

[0057] In at least one embodiment, the first partial busbar 111 may further include a first guide portion 1113, which extends from an axial end E of the first connecting portion 1112 in a direction away from the second partial busbar 112. This facilitates the arrangement of the first connecting portion 1112 and the second connecting portion 1122. However, the present application is not limited thereto, and a second guide portion may also be provided in the second partial busbar 112.

[0058] In at least one embodiment, the second abutting portion 1121 extends from an axial end F of the second connecting portion 1122 in a direction perpendicular to the axial direction, specifically, radially outward, so that the second abutting portion 1121 can abut against the surface 131 ′ of the housing 13 ′.

[0059] In at least one embodiment, the second abutting portion 1121 connects the other axial end G of the insertion portion 1123 and the axial end F of the second connecting portion 1122. Furthermore, the second abutting portion 1121, the insertion portion 1123, and the second connecting portion 1122 may be integrally formed components.

[0060] In at least one embodiment, the second connection portion 1122 has a protrusion H facing the first connection portion 1112, and the protrusion H abuts against the first connection portion 1112. However, the present application is not limited thereto, and a protrusion may also be provided on the first connection portion 1112.

[0061] In at least one embodiment, Figure 4 As shown, the number of protrusions H is one. However, the present application is not limited thereto, and the number of protrusions H may be two or more. The portion of the second connecting portion 1122 between adjacent protrusions H may be thinner than the other portions of the second busbar portion 112. This allows for easier elastic deformation in a direction perpendicular to the axial direction.

[0062] Figure 5 This is another schematic diagram of the motor 1' according to the first embodiment of the present invention, wherein the first connection portion 1112' and the second connection portion 1122' of the bus bar 11 in the motor 1' adopt the same Figure 3 and Figure 4 The bus bar 11 shown has different structures of the first connecting portion 1112 and the second connecting portion 1122. Only the differences between the motor 1' and the motor 1 will be described below.

[0063] In at least one embodiment, Figure 5 As shown, the first connecting portion 1112' has a U-shaped groove, and at least a portion of the second connecting portion 1122' (for example, the end on the other axial side) is placed in the U-shaped groove and abuts against the inner wall of the U-shaped groove, thereby electrically connecting the first connecting portion 1112' and the second connecting portion 1122'.

[0064] However, the present application is not limited thereto, and a U-shaped groove may be provided on the second connection portion 1122 ′, and at least a portion of the first connection portion 1112 ′ is placed in the U-shaped groove and abuts against the inner wall of the U-shaped groove.

[0065] In at least one embodiment, the radial distance between the inner walls of the U-shaped groove portion of the first connecting portion 1112' can be smaller than the radial thickness of the first connecting portion 1122', whereby when the first connecting portion 1122' is placed into the U-shaped groove portion, the U-shaped groove portion elastically deforms and clamps the first connecting portion 1122', thereby being able to reliably abut against the first connecting portion 1122'.

[0066] It is worth noting that the above only describes the structure of the motor related to the present invention. For other structures of the motor, reference can be made to related technologies, and the description is omitted here.

[0067] As can be seen from the above-described embodiment, by forming the bus bar into a structure in which the bus bar is formed into separate parts, the bus bar can be reliably supported and positioned.

[0075] Step 601: Abutting a first abutting portion of a first portion of a busbar against a first supporting surface of a first supporting member, with the first supporting surface facing a first direction to support the first abutting portion;

[0076] Step 602: Abut the second abutting portion of the second partial busbar against the second supporting surface of the second supporting component, so that the second supporting surface supports the second abutting portion toward the first direction, wherein the first connecting portion of the first partial busbar is electrically connected to the second connecting portion of the second partial busbar, and the distance between the first connecting portion and the second connecting portion in the first direction is variable.

[0077] According to the above embodiment, the bus bar can be reliably supported and positioned by causing the first and second bus bar portions, which are formed separately, to abut against the first and second support surfaces, respectively.
