As shown in fig. 1 to 5, the motor 10 includes an electrical connection assembly 11, an electronic component 12, and a metal plate 13. The electrical connection assembly 11 includes a resin holder 111 and a conductive portion 112 held by the resin holder 111, and the electronic component 12 is electrically connected to the conductive portion 112.

In the embodiment of the present application, the metal plate 13 is grounded, and the metal plate 13 covers the conductive portion 112 on at least one side of the resin holder 111. As shown in fig. 2 to 5, the metal plate 13 covers the conductive portion 112 on the O side in the axial direction of the resin holder 111.

However, the present application is not limited thereto, the metal plate 13 may cover the conductive portion 112 in other directions of the resin holder 111, for example, the metal plate 13 may cover the conductive portion 112 on the side of the axial direction O' of the resin holder 111, or the metal plate 13 may cover the conductive portion 112 on both the side of the axial direction O and the side of the resin holder 111, and furthermore, the metal plate 13 may cover the conductive portion 112 on the inner circumferential side of the resin holder 111, or the metal plate 13 may cover the conductive portion 112 in any combination of the above-listed directions of the resin holder 111, as long as the metal plate 13 is capable of covering at least a portion of the conductive portion 112 provided to the resin holder 111 to avoid intrusion of electromagnetic interference signals into the motor circuit. Accordingly, the shape of the metal plate 13 is not limited in the present application, and the metal plate 13 may cover the conductive portion 112 provided in the resin holder 111 in the above-described manner.

In the embodiment of the present application, the metal plate 13 may include various metal materials, for example, the metal plate 13 may be steel, and may sufficiently absorb electromagnetic interference signals, but the present application is not limited thereto, and the metal plate 13 may also include other metal materials, as long as the metal plate 13 is capable of absorbing electromagnetic interference signals.

As can be seen from the above embodiments, by providing the metal plate 13 covered on the conductive portion 112, the electromagnetic interference signal can be absorbed by the metal plate 13, and the electromagnetic interference signal absorbed by the metal plate 13 can be led out to the outside of the motor due to the grounding of the metal plate 13, thereby avoiding the influence of the electromagnetic interference signal on the motor circuit and improving the electromagnetic compatibility of the motor.

In the present embodiment, the motor 10 may be of various types, and may be, for example, a brush motor or a brushless motor. In the case where the motor 10 is a brush motor, the electrical connection assembly may be a brush-holder assembly including a resin holder to which electronic components such as inductance and capacitance are mounted, and a conductive portion provided to the resin holder, reference being made to the related art. In the case where the motor 10 is a brushless motor, the electrical connection assembly may be a bus bar unit including a resin-made bus bar holder and a metal-made bus bar, to which various electronic components of the motor are electrically connected, reference may be made to the related art.

In the following description, the motor 10 will be described by taking a brush motor as an example.

In addition, the motor 10 may be divided into a plurality of kinds according to the use situation, for example, the motor 10 may be a motor for a sunroof of a vehicle as shown in fig. 1, but the present application is not limited thereto, and the motor 10 may be used in other situations.

In the embodiment of the present application, the motor 10 may further include other components such as a housing 14, a rotation shaft, a stator, a rotor, a bearing, etc., in addition to the electrical connection assembly 11, the electronic component 12, and the metal plate 13, reference is made to the related art. In addition, in the case where the motor 10 is a sunroof motor, the motor 10 may further include a gear box assembly engaged with the rotation shaft, to which reference is made to the related art.

As shown in fig. 1, the motor 10 may further include a housing 14, where the housing 14 accommodates at least a portion of the electrical connection assembly 11, and the grounding portion 131 of the metal plate 13 abuts against the housing 14. This enables reliable grounding of the metal plate material 14.

In the present embodiment, the ground connection of the metal plate 13 may be achieved in various ways.

For example, the metal plate 13 may include a grounding portion 131 for grounding, the grounding portion 131 may abut against the chassis 14 to achieve grounding of the metal plate 13, and the grounding portion 131 may abut against an inner circumferential surface 141 (as shown in fig. 1) of the chassis 14. For example, the grounding portion 131 may be an elongated member extending in the axial direction from the edge of the main body portion of the metal plate 13, but is not limited thereto. The grounding portion 131 may also abut against other portions of the casing, such as an edge of the casing, for example, the grounding portion 131 may include a portion extending radially outward to abut against the edge of the casing; or the ground 131 may abut against both the inner peripheral surface and the edge of the casing, for example, the ground 131 may include a portion extending in the axial direction and a bent structure at a portion extending radially outward to abut against both the inner peripheral surface and the edge of the casing 14. The present application is not limited thereto, and may be selected according to actual needs. In the embodiment of the present application, the grounding portion 131 integrally formed with the metal plate 13 may be employed, whereby the fixation of the metal plate 13 can be achieved in addition to the grounding of the metal plate 13.

In some embodiments, the grounding connection of the metal plate 13 may also be achieved by other means, for example, the metal plate 13 may also be electrically connected to a grounding terminal inside the motor for grounding, which may be provided to the resin holder 111 and grounded, such as a connectable housing.

In the embodiment of the present application, the electronic component 12 may be provided in the resin holder 111 and electrically connected to the conductive portion 112, but the present application is not limited thereto, and the electronic component may be an electronic component provided at another position inside the motor, and the electronic component 12 provided in the resin holder 111 is described as an example.

In the embodiment of the present application, the electronic component 12 may be disposed at various positions of the resin holder, for example, as shown in fig. 3, the electronic component 12 may include the first electronic component 12-1 disposed on the resin holder 111 in the covering region of the metal plate 13, and may also include the second electronic component 12-2 disposed on the resin holder 111 in the uncovered region of the metal plate 13. The present application is not limited thereto, and the installation position of the electronic component in the resin holder 111 may be selected according to actual needs.

As shown in fig. 2 to 4, in one or more embodiments, an electronic component mounting portion 1112 is provided on a side of the resin holder 111 facing the metal plate 13, a through hole 133 is formed in the metal plate 13 at a position corresponding to the electronic component mounting portion 1112, the electronic component 12 includes a first electronic component 12-1 mounted to the electronic component mounting portion 1112, and the non-ground pin 12-1a of the first electronic component 12-1 penetrates through the through hole 133 and is not in contact with the metal plate 13. This ensures insulation between the non-ground pin 12-1a of the first electronic component 12-1 provided at the electronic component mounting portion 1112 and the metal plate 13, and prevents electromagnetic interference signals absorbed by the metal plate 13 from flowing into the electrical connection terminal 112a through the non-ground pin 12-1a of the first electronic component 12-1.

As shown in fig. 2 and 4, in one or more embodiments, the non-ground pin 12-1a is in an upright bent structure, in other words, the non-ground pin 12-1a extends in the axial direction at the end of the first electronic component 12-1 to be exposed from the through hole 133, and then extends in the horizontal direction to be connected to the conductive portion 112. This can further ensure that the non-ground pins of the electronic component do not contact the metal plate. However, the present application is not limited thereto, and the non-grounding pin 12-1a may be a non-upright bent structure, which is not limited thereto in the present application.

In the embodiment of the present application, as shown in fig. 2 to 5, the conductive part 112 may include an electrical connection terminal 112a protruding at a surface of the side of the resin holder 111 covered with the metal plate 13, the metal plate 13 being formed with a through hole 134 (as shown in fig. 4) at a corresponding portion corresponding to a position of the resin holder 111 where the electrical connection terminal 112a is disposed, the electrical connection terminal 112a protruding from the through hole 134 without being in contact with the metal plate 13. The non-ground pin 12-1a of the first electronic component 12-1 may be connected to the electrical connection terminal 112a to make electrical connection with the conductive portion 112. The second electronic component 12-2 may be electrically connected to the conductive portion 112 by connecting the electrical connection terminal 112a.

In the embodiment of the present application, the electronic component 12 may further include a ground pin, as shown in fig. 2 and 3, the first electronic component 12-1 includes a ground pin 12-1b, and the ground pin 12-1b may protrude from the through hole 133 of the metal plate 13 and be disposed outside the metal plate 13, so as to implement a ground connection.

For example, as shown in fig. 2 and 3, the ground pin 12-1b of the first electronic component 12-1 may be disposed outside the metal plate 13 and extend in the axial direction, whereby, in the case where the electrical connection assembly provided with the electronic component is mounted to the chassis 14, the ground pin 12-1b may be clamped by the chassis and the metal plate, thereby achieving reliable grounding of the ground pin 12-1 b. However, the present application is not limited thereto, and the grounding pin 12-1b may be grounded by, for example, welding to a metal plate.

In one or more embodiments, the electronic component mounting portion 1112 is a groove (as shown in fig. 4) formed by recessing the surface of the resin holder 111 toward the metal plate 13, that is, the groove may be the electronic component mounting portion 1112, but the present application is not limited thereto, and the electronic component mounting portion 1112 may be other shapes. The edge 1112a of the recess on the non-ground pin side is exposed from the through hole 133 as seen axially, i.e. from the O-side axially towards the electrical connection assembly. Here, the edge of the groove means a portion facing the O side of the wall portion surrounding the groove, which is called an edge portion, and as shown in fig. 3, an edge 1112a of the edge portion on the non-ground pin side protrudes toward the center of the groove with respect to the inner peripheral surface 133S of the through hole 133.

Thus, even if the non-ground pins 12-1a are of a non-upright bent structure, in the case where the non-ground pins 12-1a of the first electronic component 12-1 extend from the inside of the recess toward the outside to be connected to the conductive portions 112, the edges 1112a of the resin holder 111 may contact first without contact with the metal plate 13, and it is possible to sufficiently ensure that the non-ground pins of the electronic component do not contact with the metal plate.

As shown in fig. 3 to 5, in one or more embodiments, the conductive portions 112 are distributed on one circumferential side of the resin holder 111, and the metal plate 13 covers the conductive portions 112 on the one circumferential side. That is, the conductive portions 112 are intensively distributed in a part of the area in the circumferential direction of the resin holder 111, whereby the conductive portions 112 are intensively distributed in the circumferential direction, and the metal plate 13 in the embodiment of the present application can be molded by an integrally molding manner, thereby facilitating the production, and the material consumption of the metal plate 13 can be reduced, and the cost can be saved, as compared to the case where the conductive portions 112 are distributed in the entire circumference. However, the present application is not limited thereto, and for example, the conductive portions 112 may be distributed over the entire circumference of the resin holder 111.

As shown in fig. 4 and 5, in one or more embodiments, the metal plate 13 is integrally formed with a fixing portion 132 fixed to the resin holder 111, the fixing portion 132 being located radially outside the inner periphery 111S of the resin holder 111. The resin holder 111 may have a hollow shape, and the inner periphery 111S, that is, the radially inner side of the inner peripheral surface thereof is provided with other parts of the motor, such as a commutator, whereby the fixing portion 132 and the parts inside the inner periphery 111S of the resin holder 111 can be prevented from interfering.

In the embodiment of the present application, the fixing portion 132 may be integrally formed on the metal plate 13, in other words, as shown in fig. 4, the metal plate 13 may include the main body portion 130, and the fixing portion 132 and the main body portion 130 may be integrally formed by, for example, casting, but the present application is not limited thereto, and the fixing portion 132 may be provided on the metal plate 13 by welding or the like.

In the embodiment of the present application, the shape and the number of the fixing portions 132 are not limited, and as shown in fig. 4, the fixing portions 132 are arrow-shaped extending toward the resin holder 111, and accordingly, a plurality of receiving portions 1111 are provided at corresponding positions of the resin holder 111, each receiving portion 1111 being located radially outward of the inner periphery 111S of the resin holder 111, whereby it can be ensured that the mounting structure of the metal plate 13 and the resin holder 111 does not interfere with members provided radially inward of the inner periphery 111S of the resin holder 111.

In one or more embodiments, the conductive portion 112 includes a conductive material 1121 (see fig. 6) made of a conductive material, with an insulating portion disposed between the conductive material 1121 and the metal plate 13. This can insulate both the conductive material 1121 of the conductive portion 112 and the metal plate 13, and prevent electromagnetic interference signals absorbed by the metal plate 13 from entering the conductive portion 112 and entering the motor circuit. It is possible to further prevent electromagnetic interference signals from affecting the motor circuit.

In the present embodiment, the insulating portion between the conductive material 1121 of the conductive portion 112 and the metal plate 13 may have various embodiments, which are exemplified below.

Fig. 6 is a schematic view of a conductive portion according to an embodiment of the first aspect of the present application.

As shown in fig. 6, in one or more embodiments, the conductive portion 112 may include a conductive material 1121 and a resin portion 1122 wrapped around the outer periphery of the conductive material 1121. Thus, when the conductive portion 112 is attached to the resin holder 111, insulation between the conductive portion 112 and the metal plate 13 can be ensured.

In the embodiment of the present application, the resin portion 1122 may be coated on the outer periphery of the conductive material 1121 by injection molding, but not limited thereto, and the resin portion may be coated on the outer periphery of the conductive material 1121 by coating, for example.

In the embodiment of the present application, the resin portion 1122 is wrapped around a part of the outer periphery of the conductive material 1121, for example, the conductive material 1121 includes at least a portion not wrapped by the resin portion 1122 for electrical connection, including a portion electrically connected to an electronic component inside the motor (the electrical connection terminal 112a as described above) and a portion electrically connected to an external device (such as a power supply or a client device).

In the embodiment of the present application, the number and shape of the conductive portions 112 are not limited. As shown in fig. 6, the number of the conductive parts 112 is 2, but the present application is not limited thereto, and the number of the conductive parts 112 may be other values, such as 3, etc., and may be set according to actual needs, and in the case where the number of the conductive parts 112 is plural, it is possible to ensure that a short circuit does not occur between different conductive parts 112 by the resin part 1122 on the outer periphery thereof. Further, as shown in fig. 6, the conductive part 112 includes a vertical part extending in the axial direction and a bent part provided at one end of the vertical part, but the present application is not limited thereto, and the conductive part 112 may be of other shapes, and the shape thereof may be determined according to actual needs.

Fig. 7 is a schematic view of an electrical connection assembly of the embodiment of the first aspect of the present application, showing a case where the resin holder and the conductive portion are in an unassembled state, fig. 8 is another schematic view of the conductive portion of the embodiment of the first aspect of the present application, showing a case where the conductive portion is viewed from a different view angle from fig. 6, and fig. 9 is a schematic view of the resin holder of the embodiment of the first aspect of the present application.

As shown in fig. 7 to 9, the resin holder 111 is provided with a housing portion 1113 housing at least part of the conductive portion 112, the conductive portion 112 is inserted into the housing portion 1113 to be held by the resin holder 111, and the insulating portion is at least part of the resin portion. Thus, in the case where the conductive portion 112 itself is structured such that the outer periphery thereof is covered with the resin portion 1122, and such conductive portion 112 is inserted into the resin holder to form an electrical connection assembly, insulation between the conductive portion 112 and the metal plate 13 can be achieved by at least a part of the resin portion 1122, such as a resin portion of a portion of the conductive portion 112 facing the metal plate 13 side, and insulation between the conductive portion 112 and the metal plate 13 can be achieved in a simple manner.

However, the present application is not limited thereto, and for example, the electrical connection assembly may be formed by injection molding, that is, positioning the conductive portion 112 in a mold and then injecting resin to mold the resin holder such that the conductive portion 112 is molded inside the resin holder. Thereby, insulation between the metal plate 13 and the conductive portion 112 is achieved.

Further, insulation between the metal plate 13 and the conductive portion 112 may be achieved by other means, for example, an insulating layer may also be formed on the surface of the portion of the metal plate 13 facing the conductive portion 112, thereby achieving insulation between the metal plate 13 and the conductive portion.

In the embodiment of the present application, as for the portion of the conductive material 1121 not surrounded by the resin portion 1122, as in the electrical connection terminal 112a for connecting an electronic component shown in fig. 2 to 5, the electrical connection terminal 112a may be exposed from the corresponding through hole 134 (as shown in fig. 4) in the metal plate material 13, in which case at least the portion of the electrical connection terminal 112a corresponding to the through hole 134 in the direction perpendicular to the axial direction may also be surrounded by the resin portion, whereby insulation between the electrical connection terminal 112a and the metal plate material 13 may be ensured, but the present application is not limited thereto, for example, an insulating layer may also be formed at least in the peripheral wall portion of the through hole 134 to ensure insulation between the electrical connection terminal 112a and the metal plate material 13.

As shown in fig. 8 and 9, in one or more embodiments, the conductive material 1121 includes a first engagement portion 1121a exposed to the resin portion 1122, and the resin holder 111 includes a second engagement portion 1113a provided to an inner wall of the accommodating portion 1113, the first engagement portion 1121a and the second engagement portion 1113a being engaged with each other to fix the conductive portion 112 to the resin holder 111. In this way, in the structure in which the conductive portion 112 is assembled to the resin holder 111 by insertion, the first engagement portion 1121a and the second engagement portion 1113a are engaged with each other and fixed, so that easy and reliable fixation can be achieved.

In the embodiment of the present application, the specific shape of the first fitting portion 1121a and the second fitting portion 1113a is not limited, and for example, they may be a shape that engages with each other, or a concave-convex shape that engages with each other. In addition, the number of the first engaging portions 1121a and the second engaging portions 1113a is not limited, and may be 1, 2, 3 or more than 3, for example, according to actual needs.

It is to be noted that the above-described first fitting portion 1121a and second fitting portion 1113a are not necessarily structured, and for example, in the case of forming the electrical connection assembly by injection molding, a fixing structure for fixing the conductive portion 112 and the resin holder 111 need not be provided.

The motors according to the embodiments of the present application have been described above from different angles by different embodiments, and the above embodiments may be arbitrarily combined, and the description thereof will be omitted. Further, the present application has been described above by way of example only, but the present application is not limited thereto, and appropriate modifications may be made on the basis of the above embodiments.

According to the above embodiment of the present application, by providing the metal plate 13 covered on the conductive portion 112, the electromagnetic interference signal can be absorbed by the metal plate 13, and the electromagnetic interference signal absorbed by the metal plate 13 can be led out to the outside of the motor due to the grounding of the metal plate 13, thereby, the electromagnetic interference signal can be prevented from affecting the motor loop, and the electromagnetic compatibility of the motor is improved.
