However, the metal end cover formed by stamping with a high-speed punch and a high-precision drawing die is heavy, which affects the weight of the motor. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] To this end, a first aspect of the utility model provides an end cover.

The bearing chamber is arranged in a ring shape. The first side of the bearing chamber is connected to the main body, and the second side of the bearing chamber extends along a first direction away from the main body; wherein the main body and the bearing chamber are an integrated structure of thermosetting material.

[0008] The end cover provided in the present application is used for an electric component. The end cover can protect the electric component. The end cover includes a body and a bearing chamber. The bearing chamber is arranged in a ring shape. The first side of the bearing chamber is connected to the body, and the second side of the bearing chamber extends along the first direction away from the body; wherein the body and the bearing chamber are an integrated structure of thermosetting material, which can reduce the overall weight of the end cover while simplifying the process difficulty of the end cover in the production process, reduce the production cost of the end cover, and thus reduce the production cost of the electric component. At the same time, the integrated injection molding of the body and the bearing chamber can also improve the production efficiency of the end cover and improve the installation efficiency of the electric component. Since one side of the annular bearing chamber is connected to the body and the other side extends in the first direction, the annular structure of the bearing chamber can improve the smoothness of the bearing rotation and avoid the bearing from getting stuck during the installation and operation of the electric component.

[0009] At the same time, due to the strong plasticity of thermosetting materials, the corresponding feeding ratio can be selected according to the shape and size of the end cover, which can improve the utilization rate of the material. At the same time, due to the high stability and insulation of thermosetting materials, there is no need to set anti-electrolytic corrosion components, and there is no need to perform additional conduction operations on the end covers, which reduces the cost of the electric components, reduces the operating steps of the electric components, and improves the working efficiency of the electric components.

[0010] In addition, the end cover in the above technical solution provided by the utility model may also have the following additional technical features:

[0012] In this technical solution, the one-piece structure of the thermosetting material includes the one-piece structure of the unsaturated polyester bulk molding compound. By setting the unsaturated polyester bulk molding compound as the thermosetting material with an one-piece structure, the flame retardancy and insulation of the end cover during operation can be improved, so that the end cover can be anti-static during the operation of the electric component. At the same time, due to the high chemical stability of the unsaturated polyester bulk molding compound, the body and bearing chamber made of the unsaturated polyester bulk molding compound can prevent electrical corrosion, and avoid the end cover from mixing with grease, thereby improving the durability of the end cover, extending the service life of the end cover, and reducing the maintenance cost of the electric component.

[0013] At the same time, the one-piece structure of unsaturated polyester bulk molding compound is used as the one-piece structure of the thermosetting material, which can reduce the shrinkage rate of the material after molding and cooling, and improve the accuracy of end cap manufacturing.

The stability of the bearing chamber can be improved by setting the connecting ribs, and the stability of the end cover structure can be improved to improve the strength of the end cover structure, which facilitates the installation of the end cover and extends the service life of the end cover.

[0016] During the injection molding of the end cover, multiple connecting ribs connected to the bearing chamber can also improve the consistency of the shrinkage deformation of the bearing chamber during the injection molding process, thereby improving the consistency of the inner diameter of each position of the bearing chamber after the injection molding is completed. During the motor installation process, the inner diameter of each position of the bearing chamber has a higher consistency, making the internal space of the bearing chamber more closely matched to the bearing size, facilitating the installation of the bearing, reducing the risk of wear between the bearing and the bearing chamber, and improving the stability of the bearing during operation.

[0017] Specifically, the number of connecting ribs may be set according to the actual size of the end cover.

[0018] Specifically, the size and quantity of the connecting ribs can be adjusted according to the shrinkage ratio of the injection molding material before and after processing.

[0027] In this technical solution, the length L1 of the third edge in the second direction, the height H of the connecting rib in the first direction and the angle θ1 of the first angle satisfy the following relationship: L1 = H × tan (π-θ1), so the third edge and the connecting rib, by setting a size range and limiting the size relationship between the length L1 of the third edge in the second direction, the height H of the connecting rib in the first direction and the angle θ1 of the first angle, can make the connecting rib form a triangular structure, thereby improving the stability between the connecting rib and the body and the bearing chamber, improving the stability of the overall structure, extending the service life of the end cover, and also improving the rigidity of the end cover, while reducing the production cost of the end cover, thereby reducing the production cost of the electric component, and at the same time, the integrated injection molding of the body and the bearing chamber can also improve the production efficiency of the end cover and improve the installation efficiency of the electric component, because one side of the annular bearing chamber is connected to the body and the other side extends in the first direction, the annular structure of the bearing chamber can improve the smoothness of the bearing rotation and avoid the bearing getting stuck during the installation and operation of the electric component.

[0052] like Figure 1 As shown, the first aspect of the utility model provides an end cover 100, which is used for an electric component. The end cover 100 includes a body 110 and a bearing chamber 120. The bearing chamber 120 is arranged in a ring shape, and a first side of the bearing chamber 120 is connected to the body 110, and a second side of the bearing chamber 120 extends along a first direction away from the body 110; wherein the body 110 and the bearing chamber 120 are an integrated structure of thermosetting material.

[0053] The end cover 100 provided in the present application is used for an electric component. The end cover 100 can protect the electric component. The end cover 100 includes a body 110 and a bearing chamber 120. The bearing chamber 120 is arranged in a ring shape. The first side of the bearing chamber 120 is connected to the body 110, and the second side of the bearing chamber 120 extends in a first direction away from the body 110; wherein the body 110 and the bearing chamber 120 are an integrated structure of thermosetting material, which can reduce the overall weight of the end cover 100 while simplifying the process difficulty of the end cover 100 in the production process, reduce the production cost of the end cover 100, and thus reduce the production cost of the electric component. At the same time, the integrated injection molding of the body 110 and the bearing chamber 120 can also improve the production efficiency of the end cover 100 and improve the installation efficiency of the electric component. Since one side of the annular bearing chamber 120 is connected to the body 110 and the other side extends in the first direction, the annular structure of the bearing chamber 120 can improve the smoothness of the bearing rotation and avoid the bearing getting stuck during the installation and operation of the electric component.

[0054] At the same time, due to the strong plasticity of thermosetting materials, the corresponding feeding ratio can be selected according to the shape and size of the end cover 100, which can improve the utilization rate of the material. At the same time, due to the high stability and insulation of thermosetting materials, anti-electrolytic corrosion components are no longer required and there is no need to perform additional conduction operations on the end cover 100, thereby reducing the cost of the electric component, reducing the operating steps of the electric component, and improving the working efficiency of the electric component.

[0055] Specifically, the end cover 100 may also be provided with a positioning groove 150 , through which the end cover 100 may be positioned, and at the same time, the installation of the end cover 100 may be facilitated, thereby improving the overall stability.

At the same time, due to the high chemical stability of the unsaturated polyester bulk molding material, the main body 110 and the bearing chamber 120 made of the unsaturated polyester bulk molding material can prevent electrical corrosion and avoid the end cover 100 from mixing with grease, thereby improving the durability of the end cover 100, extending the service life of the end cover 100, and reducing the maintenance cost of the electric component.

[0060] At the same time, the one-piece structure of the unsaturated polyester bulk molding compound is used as the one-piece structure of the thermosetting material, which can reduce the shrinkage rate of the material after molding and cooling, and improve the manufacturing accuracy of the end cap 100.

[0061] Specifically, when the end cap 100 is made of unsaturated polyester bulk molding compound material, the shrinkage rate of the material after molding and cooling is less than 0.005 mm, which can reduce the cost of the end cap 100 and facilitate the injection molding process of the end cap 100.

[0065] During the injection molding of the end cover 100, the multiple connecting ribs 130 connected to the bearing chamber 120 can also improve the consistency of the shrinkage deformation of the bearing chamber 120 during the injection molding process, thereby improving the inner diameter of each position of the bearing chamber 120 to have a higher consistency after the injection molding is completed. During the motor installation process, the inner diameter of each position of the bearing chamber 120 has a higher consistency, so that the internal space of the bearing chamber 120 is more closely matched with the bearing size, which facilitates the installation of the bearing, reduces the risk of wear between the bearing and the bearing chamber 120, and improves the stability of the bearing during operation.

[0066] Specifically, the number of the connecting ribs 130 may be set according to the actual size of the end cover 100 .

[0067] Specifically, the size and quantity of the connecting ribs 130 may be adjusted according to the shrinkage ratio of the injection molding material before and after processing.

By setting the angle between the third edge 136 and the surface of the body 110 on the side where the bearing chamber 120 is provided to be greater than 120 degrees, the strength between the connecting rib 130, the body 110 and the bearing chamber 120 can be improved, and at the same time, limiting the first angle to be greater than or equal to 120 degrees and less than or equal to 160 degrees can reduce the volume of the connecting rib 130 while ensuring the structural strength, thereby reducing the weight of the connecting rib 130, so that the overall weight of the overall end cover 100 can be reduced, the production cost of the end cover 100 can be reduced, and the utilization rate of materials can be improved.
