Description

Technical Field

[0001] This application relates to the field of copper busbar structures, and in particular to a star-shaped copper busbar. Background Technology

[0002] Currently, the stator windings of flat-wire motors are typically connected to star-shaped copper busbars, which serve for signal and power transmission. Therefore, the structure of these star-shaped copper busbars affects the overall size of the stator; a smaller stator is easier to integrate into complex motor assemblies. However, the existing structure of these star-shaped copper busbars dictates that they can only be placed on the outside of the stator windings, leading to an increase in the overall size of the stator. Utility Model Content

[0003] In view of this, the purpose of this application is to provide a star-shaped copper busbar to solve the problem that the structure of the existing star-shaped copper busbar can only be arranged on the outside of the stator winding, thereby increasing the overall volume of the stator.

[0004] To achieve the above objectives, this utility model provides a star-shaped copper busbar for connection to the stator of a flat wire motor, wherein the star-shaped copper busbar comprises:

[0005] The main body is located inside the stator;

[0006] Connection pins, a plurality of connection pins are spaced apart on the side of the main body, each connection pin is formed as a bent structure to extend to the outside of the stator, and the connection pins are connected one-to-one with the windings of the stator.

[0007] Preferably, the main body is formed as an arc-shaped structure corresponding to the stator, and the main body arches toward the side where the winding is located.

[0008] Preferably, the connection pin is located on the outer side of the body near the winding.

[0009] Preferably, the connection pins are formed with sequentially connected transition portions and solder portions.

[0010] Preferably, the transition portion is formed with a first horizontal segment and a first vertical segment connected in sequence, so that the transition portion is formed into an L-shaped structure.

[0011] Preferably, the first horizontal segment extends radially away from the body and along the axial direction of the stator, the thickness of the first horizontal segment is the same as the thickness of the body.

[0012] Preferably, the first vertical segment is located at the end of the first horizontal segment away from the main body, and the first vertical segment extends along the axial direction of the stator; a rounded structure is formed at the connection between the first vertical segment and the first horizontal segment.

[0013] Preferably, the welded portion is formed with a second horizontal segment and a second vertical segment connected in sequence, so that the welded portion is also formed as the L-shaped structure.

[0014] Preferably, the end of the second horizontal segment away from the second vertical segment is connected to the end of the first vertical segment away from the first horizontal segment.

[0015] Preferably, the second vertical segment extends along the axial direction of the main body towards the main body, and the side of the second vertical segment facing the stator is in contact with the winding, and the second vertical segment is welded to the winding accordingly.

[0016] According to the present invention, the star-shaped copper busbar is connected to the stator winding (outer side) one by one through multiple connecting pins. When the two are connected, the main body of the star-shaped copper busbar can be located inside the stator due to the bending structure of the connecting pins, thus effectively reducing the overall volume of the stator.

[0031] This utility model provides a star-shaped copper busbar for connecting to the stator 2 of the flat wire motor, such as... Figures 1 to 2 As shown, the star-shaped copper busbar 1 in this embodiment includes a main body 10 and a plurality of connecting pins 11 disposed on the side of the main body 10. The main body 10 provides support for the connecting pins 11 to ensure the consistency and stability of the overall structure of the star-shaped copper busbar 1. The connecting pins 11 are used to connect with the windings 20 of the stator 2. The specific structure and connection relationship of the above-mentioned parts of the star-shaped copper busbar according to this utility model will be described in detail below.

[0032] In this embodiment, when the star-point copper busbar 1 is connected to the stator 2 winding 20, the main body 10 is located inside the stator 2, that is, on the side of the stator 2 winding 20 close to the central axis of the stator 2. The main body 10 is formed into an arc-shaped structure corresponding to the stator 2, and the main body 10 arches towards the side where the winding 20 is located. This can improve the compatibility of the star-point copper busbar 1 and the overall structure of the stator 2, so as to improve the stability after the two are connected.

[0033] Furthermore, multiple connection pins 11 are spaced apart on the outer side of the main body 10 near the winding 20. Each connection pin 11 is formed as a bent structure to extend to the outer side of the stator 2 (winding 20), thereby facilitating a one-to-one connection between the connection pins 11 and the windings 20 of the stator 2. Specifically, as shown... Figure 2 As shown, in this embodiment, the connection pin 11 has a transition portion 110 and a solder portion 111 connected in sequence. The transition portion 110 has a first horizontal segment and a first vertical segment connected in sequence, so that the transition portion 110 is formed into an L-shaped structure; the solder portion 111 has a second horizontal segment and a second vertical segment connected in sequence, so that the solder portion 111 is also formed into the L-shaped structure.

[0034] More specifically, such as Figure 2 As shown, the aforementioned first horizontal segment extends radially away from the main body 10 and along the axial direction of the stator 2 (i.e., Figure 2 The thickness of the first horizontal segment (Y-axis) is the same as that of the main body 10. That is, in this embodiment, the top and bottom of the first horizontal segment are flush with the top and bottom of the main body 10, which helps to improve the rigidity and strength of the overall structure of the star-shaped copper busbar 1. In addition, the first vertical segment is located at the end of the first horizontal segment away from the main body 10, and the first vertical segment extends along the axial direction (downward) of the stator 2. Furthermore, the connection between the first vertical segment and the first horizontal segment has a rounded structure to improve the structural strength of the transition portion 110.

[0035] Furthermore, the end of the second horizontal segment away from the second vertical segment is connected to the end of the first vertical segment away from the first horizontal segment. The second vertical segment extends along the axial direction of the main body 10 towards the direction close to the main body 10 (i.e., extends upwards), and the side of each second vertical segment facing the stator 2 can fit against the corresponding winding 20 (outer side). Furthermore, the second vertical segment is welded to the winding 20 to form a solder joint at the top of the winding 20 and the second vertical segment. In this way, a stable connection between the star copper busbar 1 and the stator 2 can be achieved while saving space.

[0036] It should be noted that the specific specifications and quantities of the various structures of this star-shaped copper busbar 1 are not fixed and should be determined comprehensively based on the actual situation, such as the specifications, spacing, and quantity of the windings 20, as long as the above technical effects can be achieved.

[0037] According to the present invention, the star-shaped copper busbar is connected one-to-one with the outer side of the stator 2 winding 20 through multiple connecting pins 11. When the two are connected, the main body 10 of the star-shaped copper busbar 1 can be located inside the stator 2 due to the bending structure of the connecting pins 11. This effectively reduces the overall volume of the stator 2, making it easier for the stator 2 to be arranged in a motor with a complex structure.

[0038] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
