DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0038] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0039] like Figure 1 , 7 As shown in 9 to 11, in the first aspect, the embodiment of the present application provides a conductive structure, including a seal 1 sleeved on the outer surface of the motor shaft 6, which can seal the axial direction of the motor shaft 6, and the seal 1 is provided with a accommodating chamber 11, and the support member 2 is a metal member, which is partially located in the accommodating chamber 11, and can support the seal 1 to improve the sealing performance of the seal 1; the support member 2 includes a plurality of protrusions 21 located at the edge, and the outer wall of the seal 1 is provided with a plurality of notches 12, the protrusions 21 protrude from the notches 12, and can contact the parts of the motor, the conductive structure also includes a conductive member 3, the conductive member 3 is connected to the support member 2, the conductive structure also includes a plurality of conductive beams 4, the plurality of conductive beams 4 are respectively connected to the conductive member 3 along the radial direction of the conductive member 3, and contact the motor shaft 6, so that part of the current on the motor shaft 6 is transferred to the conductive member 3 through the conductive beam 4, the conductive member 3 is connected to the support member 2, and the current is transferred from the support member 2 to the parts of the motor to discharge the current on the motor shaft 6. In the present application, the conductive structure can realize both the sealing function and the conductive function, and the sealing structure and the conductive structure are integrated, which can reduce the space in the motor shaft 6 direction.

[0040] In addition, in the embodiment of the present application, since the conductive bundle 4 is separated from the lubricating oil space by the seal 1, it is also possible to avoid the conductive bundle 4 from gathering together due to oil adsorption, reducing the contact between the conductive bundle 4 and the motor shaft 6, thereby reducing the conductive effect.

[0041] Optionally, the parts of the motor may include the motor housing or the end cover of the motor, that is, the protrusion 21 may contact the motor housing or the end cover of the motor; of course, it may also contact other parts in the housing, thereby conducting the current through the housing.

[0042] Optionally, the seal 1 can be a rubber part, which is wrapped around the outer surface of the support 2 through a vulcanization process. Of course, the seal 1 can be made of at least two pieces spliced ​​together and then glued to the support 2 to wrap a part of the support 2 in the accommodating chamber 11.

[0043] Optionally, the support member 2 may be made of metal such as copper or carbon steel.

[0044] Optionally, the conductive structure may be installed on one side of the bearing to seal the bearing.

[0045] like Figure 3 and 9 As shown, as an embodiment, the sealing member 1 is provided with an annular opening 13, which is connected to the accommodating chamber 11; the supporting member 2 includes a plug-in portion 22, which protrudes from the annular opening 13. By setting the annular opening 13, a part of the supporting member 2 is located in the accommodating chamber 11, and the other part can be connected to the conductive member 3.

[0046] like Figure 3 and 8 As shown, as an embodiment, the support member 2 also includes a support body 23, the support body 23 is connected to the plug-in portion 22, the support body 23 is located in the accommodating chamber 11, and the radial dimension of the plug-in portion 22 is smaller than the radial dimension of the support body 23, so that when the plug-in portion 22 is connected to the conductive member 3, it is equivalent to reducing the radial dimension of the conductive member 3, thereby further reducing the radial length of the conductive beam 4, which can reduce costs on the one hand; on the other hand, it is convenient to make the overall structure of the conductive beam 4 stable, and when the motor shaft 6 rotates, it can also contact the motor shaft 6, thereby improving the conductive effect.

[0047] Optionally, the annular opening 13 is equivalent to the notch 12 and is located on the inner side of the seal 1 in the radial direction, that is, closer to the center of the seal 1 , corresponding to the plug-in portion 22 , so that the plug-in portion 22 can protrude from the annular opening 13 and connect with the conductive member 3 .

[0048] like Figure 1 , 2 As shown in Figure 8, as an embodiment, the outer wall of the seal 1 includes a first wall 111 and a second wall 112 that are connected to each other. The first wall 111 extends axially, and the second wall 112 extends radially. The notch 12 is arranged at the bending position of the first wall 111 and the second wall 112. In this way, when the protrusion 21 protrudes from the notch 12, it can avoid the protrusion 21 from the radial direction of the seal 1, that is, it can avoid protruding from the first wall 111. If the protrusion 21 protrudes from the radial direction of the seal 1, it will occupy the radial width of the conductive structure, thereby reducing the sealing performance. The notch 12 is arranged at the bending position of the first wall 111 and the second wall 112, which is equivalent to the protrusion 21 extending along the inclined direction. In this way, the support member 2 can be abutted against the parts of the motor, and at the same time, the radial space of the seal 1 occupied by the protrusion 21 can be reduced, so that the outer surface of the seal 1 can seal the bearing on the motor shaft 6, thereby improving the sealing performance.

The protrusion 21 is located at the bending position of the first section 24 and the second section 25, and extends obliquely, so that the support member 2 can abut against the parts of the motor, and at the same time, it can reduce the radial space occupied by the protrusion 21.

[0062] like Figure 5As shown, as an embodiment, two adjacent plug-in pieces 221 are spaced apart to form a groove. When the plug-in piece 221 is inserted into the plug-in slot 31, the main body 41 is embedded in the groove. The groove can limit the main body 41 to improve the stability between the conductive beam 4 and the support member 2 and the conductive member 3.
