[0047] Please refer to Figures 1-4 , Figure 1 which is a connection structure diagram of the motor support, the mounting beam, and the motor provided by the present invention, Figure 2 which is a schematic structural diagram of a specific embodiment of the first metal insert or the second metal insert, Figure 3 which is a schematic structural diagram of another specific embodiment of the first metal insert or the second metal insert, Figure 4Schematic structural diagram of a specific embodiment of the gasket.

[0048] As Figure 1 shown, the present invention provides a motor support 200 for mounting the motor 500 on the bogie. The bogie may include a mounting beam 100, and the motor support 200 may be specifically mounted on the mounting beam 100.

[0049] The mounting beam 100 may be a cross beam, a longitudinal beam or other beam bodies of the bogie, etc. Specifically, it is related to the mounting position of the motor support 200 on the bogie and is not limited herein. The mounting beam 100 may be a tubular beam, such as Figure 1 a beam body with a generally rectangular cross-section; or, the mounting beam 100 may also be a beam body with an H-shaped, U-shaped or I-shaped cross-section.

[0050] Further, in the embodiments of the present invention, both the mounting beam 100 and the motor support 200 are made of carbon fiber material to facilitate weight reduction. At the same time, compared with metal materials, the carbon fiber material can have better performance in terms of corrosion resistance and fatigue resistance.

[0051] The motor support 200 includes a first mounting portion 200a and a second mounting portion 200b.

[0052] The first mounting portion 200a and the mounting beam 100 are connected by rivets 300; and / or, at least one of the first mounting portion 200a and the mounting beam 100 is provided with a first metal insert 200c, and the first metal insert 200c can cooperate with the bolt assembly 400 to connect the first mounting portion 200a and the mounting beam 100. In this embodiment, the connection between the carbon fiber material motor support 200 and the mounting beam 100 can be effectively realized, and it is not easy to damage the motor support 200 and the mounting beam 100, and the connection reliability is also relatively high.

[0053] It should be understood that the mounting beam 100 may also be made of metal material. At this time, the connection between the first mounting portion 200a and the mounting beam 100 can be only through the way of setting the first metal insert 200c to reduce the damage to the motor support 200.

[0054] Similarly, the second mounting portion 200b is provided with a second metal insert 200d, and the second metal insert 200d can cooperate with the bolt assembly 400 to connect the motor 500 and the second mounting portion 200b. In this embodiment, when the motor support 200 is connected to the motor 500, it is not easy to damage the carbon fiber material motor support 200, and the connection reliability between the motor 500 and the motor support 200 can be effectively improved.

[0055] Here, the embodiments of the present invention do not limit the number and installation positions of the rivets 300, the first metal insert 200c, and the second metal insert 200d. In practical applications, those skilled in the art can configure them according to specific needs as long as the usage requirements can be met. Exemplarily, reference can be made to Figure 1 the solution shown.

[0056] In addition, the embodiments of the present invention do not limit the structures of the first metal insert 200c and the second metal insert 200d. In practical applications, those skilled in the art can configure them according to specific needs as long as they can cooperate with the bolt assembly 400 to complete the connection between relevant components. Exemplarily, reference can be made to Figure 1 the solution shown.

[0057] In some embodiments, as Figure 2 shown, in the first metal insert 200c and the second metal insert 200d, at least one of them may include a substrate 200d-1 and an embedding portion 200d-2 disposed on the substrate 200d-1. Among them, the embedding portion 200d-2 is used to realize the embedding of the metal insert in the mounting beam 100 and the motor support 200, and the substrate 200d-1 is used to form an abutment with the mounting beam 100, the motor support 200, etc., for defining the installation depth of the metal insert.

[0058] The embedding portion 200d-2 is provided with a through hole.

[0059] The above through hole can be a threaded hole. In this case, the bolt assembly 400 may only include a bolt. The bolt includes a rod portion and a head. The rod portion can be threadedly connected to the through hole, and the head can be pressed to complete the connection between the motor support 200 and the mounting beam 100, and the connection between the motor 500 and the motor support 200. Alternatively, the through hole can also be a clearance hole. In this case, the bolt assembly 400 may include a bolt and a nut. The bolt also includes a rod portion and a head. The rod portion can pass through the through hole and can be connected to the nut. Both the head and the nut can be pressed to complete the connection between the motor support 200 and the mounting beam 100, and the connection between the motor 500 and the motor support 200.

[0060] For one embedding portion 200d-2, the number of through holes can be one or multiple, and can be specifically set according to actual needs.

[0061] Similarly, for a metal insert, the number of the configured embedding parts 200d-2 can be one or more. When the number of the embedding parts 200d-2 is more than one, the substrate 200d-1 can not only play a limiting role, but also establish a structural connection between the embedding parts 200d-2. In this way, after the metal insert is embedded, the structural strength of the mounting beam 100 or the motor support 200 embedded with the metal insert can be improved, and it is beneficial to improve the connection reliability between the motor support 200 and the mounting beam 100, and between the motor support 200 and the motor 500.

[0062] After the embedding is completed, the embedding part 200d-2 can have a protruding part, for example Figure 1 In the embodiment, the two first metal inserts 200c located at the lower left corner and the second metal insert 200d located at the lower right corner, this protruding part may affect the connection of the bolt assembly 400. For this reason, a gasket 200e can also be provided, as Figure 4 shown, the gasket 200e can have a receiving part 200e-1, and the receiving part 200e-1 can receive the protruding part to facilitate the mating connection between the bolt assembly 400 and the metal insert.

[0063] It should be understood that the embedding part 200d-2 may not have a protruding part either. In this way, the influence on the installation can be reduced, for example Figure 1 the second metal insert 200d located at the upper right corner in the embodiment, etc.; specifically, the size of the embedding part 200d-2 can be controlled to be less than or equal to the total thickness of the parts to be connected. For example, it can be about 0.2 mm - 0.5 mm smaller. It should be noted that even if the embedding part 200d-2 does not have a protruding part, the gasket 200e can still be present. At this time, the main function of the gasket 200e is to increase the contact area, thereby improving the connection reliability.

[0064] In some other embodiments, as Figure 3 shown, in the first metal insert 200c and the second metal insert 200d, at least one of them can further include an extension part 200d-3. The extension part 200d-3 and the embedding part 200d-2 can be respectively located on both sides of the substrate 200d-1. The setting of the extension part 200d-3 can extend the mating dimension between the metal insert and the bolt assembly 400, and thus can improve the connection reliability between the bolt assembly 400 and the metal insert.

[0065] The motor support 200 can be an integral structure. At this time, the motor support 200 can be formed in one step, and the preparation process of the motor support 200 can be relatively simple.

[0066] Alternatively, the motor support 200 can also be of a split structure. In this case, the structural forms of the individual parts will be relatively simple, facilitating processing. Especially when the overall structure of the motor support 200 is relatively complex, the split design can significantly reduce the processing difficulty of the motor support 200 and is conducive to ensuring the processing quality.

[0067] Here, the embodiments of the present invention do not limit the number of parts included in the split motor support 200. In practical applications, those skilled in the art can configure it according to specific needs, as long as the usage requirements can be met.

[0068] In an exemplary solution, as Figure 1 shown, the motor support 200 can include two parts, namely a first seat body 210 and a second seat body 220. In this implementation, the number of parts is relatively small, which can simplify the installation process and can meet various requirements such as easy processing and convenient installation. It should be noted that the following embodiments of the present invention will describe the specific structure of the motor support 200 by taking the solution with two parts as an example.

[0069] Both the first seat body 210 and the second seat body 220 can include a first mounting portion 200a and a second mounting portion 200b. At this time, both the first seat body 210 and the second seat body 220 can achieve connection with the mounting beam 100 and the motor 500. The motor 500 can be installed and positioned through multiple seat bodies, and the reliability of the installation can be improved.

[0070] Please refer to Figures 5-9 , Figure 5 which is a schematic structural diagram of the first seat body, Figure 6 is Figure 5 the top view of Figure 7 is the ply structure diagram of the first seat body, Figure 8 is Figure 7 the sectional view in the A-A direction of Figure 9 is Figure 7 the sectional view in the B-B direction of

[0071] As Figure 5 shown, the first seat body 210 can include a T-shaped part 210a. The T-shaped part 210a can include a first horizontal part 210a-1 and a first vertical part 210a-2. The first horizontal part 210a-1 can include a first side part 210a-1a and a second side part 210a-1b located on both sides of the first vertical part 210a-2; both the first side part 210a-1a and the first vertical part 210a-2 can have a first mounting portion 200a for connecting with the mounting beam 100; the second side part 210a-1b has a second mounting portion 200b for connecting with the motor 500.

[0072] The first base body 210 may further include a first reinforcing member 210b, which is used to connect the second side portion 210a-1b and the first vertical portion 210a-2, and can enhance the structural strength of the first base body 210. The number of the first reinforcing members 210b is not limited herein and can be specifically determined according to the structural dimensions of the T-shaped member 210a, etc.

[0073] Combined with Figure 5 and Figure 6 , a second metal insert 200d disposed on the second side portion 210a-1b, whose substrate 200d-1 can be strip-shaped, and a plurality of embedding portions 200d-2 can be disposed on the strip-shaped substrate 200d-1 to achieve the structural connection between the plurality of embedding portions 200d-2, thereby enhancing the structural strength of the first base body 210. The first side portion 210a-1a may be provided with riveting holes 200a-1 for installing rivets 300, and the rivets 300 can achieve the connection between the first side portion 210a-1a and the mounting beam 100.

[0074] During specific processing, the first base body 210 can be prepared by a layering process. Combined with Figures 7-9 , the first base body 210 may include a first layering portion 211, a second layering portion 212, a third layering portion 213, a fourth layering portion 214, and a fifth layering portion 215.

[0075] The first layering portion 211 can be flat and is used to participate in forming the first horizontal portion 210a-1, and the thickness of the first layering portion 211 can be denoted as a1.

[0076] The second layering portion 212 and the third layering portion 213 can be on the same side of the first layering portion 211, and both can be in an L shape, including a first part and a second part arranged at an angle. For the convenience of description, the first part of the second layering portion 212 can be called the second first layering part 212a, and the second part of the second layering portion 212 can be called the second second layering part 212b. The first part of the third layering portion 213 can be called the third first layering part 213a, and the second part of the third layering portion 213 can be called the third second layering part 213b.

[0077] The second laying portion 212 and the third laying portion 213 can be oppositely arranged. The first part 212a of the second laying portion can be attached to the first laying portion 211 to cooperate with the first laying portion 211 to form the first side portion 210a-1a. The first part 213a of the third laying portion can be attached to the first laying portion 211 to participate in forming the second side portion 210a-1b in cooperation with the first laying portion 211. The second part 212b of the second laying portion and the second part 213b of the third laying portion can be attached to each other to participate in forming the first vertical portion 210a-2. The thickness of the second laying portion 212 can be denoted as a2, and the thickness of the third laying portion 213 can be denoted as a3.

[0078] The thicknesses of the first laying portion 211, the second laying portion 212, and the third laying portion 213 can satisfy the following relationship: a1 = a2 + a3. Of course, there can be other relationships among the thicknesses of the three laying portions, which are not limited herein.

[0079] The gap area between the first laying portion 211, the second laying portion 212, and the third laying portion 213 can be filled with the fifth laying portion 215 to enhance the connection strength between the first laying portion 211, the second laying portion 212, and the third laying portion 213.

[0080] The fourth laying portion 214 can include a first attaching portion 214a and a first strengthening portion 214b. The first strengthening portion 214b can be used to form the first strengthening member 210b; combined Figure 8 and Figure 9 , the first strengthening member 210b can actually be formed by attaching two first strengthening portions 214b to each other. The first attaching portion 214a is used to attach to the third laying portion 213 so that the fourth laying portion 214 can be connected to the third laying portion 213, thereby improving the connection reliability between the fourth laying portion 214 and the third laying portion 213. The thickness of the fourth laying portion 214 can be denoted as a4.

[0081] The gap area between the fourth laying portion 214 and the third laying portion 213 can also be filled with the aforementioned fifth laying portion 215 to enhance the connection strength between the fourth laying portion 214 and the third laying portion 213.
