Description

Technical Field

[0001] The utility model relates to the technical field of motor copper bar groups, in particular to a motor slip ring copper bar group. Background Art

[0002] In modern motor technology, the busbar group is an important component that connects the various parts inside the motor. Its performance directly affects the working efficiency and safety of the motor. Steering motors are widely used in automobiles and electric vehicles, and they are required to maintain stable current transmission under high load and high frequency working environments.

[0003] Existing copper busbar sets typically consist of 3-5 rows of copper busbars, arranged one above the other to achieve efficient current conduction. Industry standards require the breakdown voltage between different copper busbars to be maintained above 800V to ensure safe operation under high-voltage conditions. However, due to the extremely small spacing between the copper busbars, any slight deformation during the manufacturing process can lead to a decrease in the electrical insulation performance between the copper busbars, resulting in a lower breakdown voltage and even a short circuit failure.

[0004] Traditional manufacturing processes often struggle to ensure precise positioning and shape control of copper busbars, significantly challenging their reliability in practical applications. Deformation of the busbars can significantly increase the risk of electrical failure, especially in high-temperature and high-frequency operating environments. To address this, we offer a motor slip ring copper busbar assembly. Utility Model Content

[0005] 1) Technical problems solved

[0006] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide a motor busbar assembly.

[0007] 2) Technical solution

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a motor slip ring copper bar group, comprising a copper bar component formed by stacking and arranging a first copper bar component, a second copper bar component and a third copper bar component.

[0009] The first copper bar assembly includes a first L-bar and a first circular bar, the first circular bar is fixedly connected to a first connecting plate, one end of the first L-bar is welded to the first connecting plate, and the first circular bar is also fixedly connected to a first connecting buckle.

[0010] The second copper bar assembly includes a second L-row and a second circular row, the second circular row is fixedly connected to a second connecting plate, one end of the second L-row is welded to the second connecting plate, and the second circular row is also fixedly connected to a second connecting buckle.

[0011] Among them, the third copper bar assembly includes a third L row and a third circular row, the third circular row is fixedly connected to a third connecting plate, one end of the third L row is welded to the third connecting plate, and the third circular row is also fixedly connected to a third connecting buckle.

[0012] Furthermore, the first circular row, the second circular row and the third circular row are coaxially arranged.

[0013] Furthermore, a first mounting hole is formed on the first circular row, and a first widening member matching the first mounting hole is fixedly connected to the first circular row.

[0014] Furthermore, a second mounting hole is formed on the second circular row, and a second widening member matching the second mounting hole is fixedly connected to the second circular row.

[0015] Furthermore, a third mounting hole is formed on the third circular row, and a third widening member matching the third mounting hole is fixedly connected to the third circular row.

[0016] Furthermore, the first connecting buckles, the first connecting plates and the third connecting buckles are arranged alternately on the copper busbar component.

[0017] 3) Beneficial effects:

[0018] Compared with the existing technology, the motor busbar assembly has the following beneficial effects:

[0019] This utility model adopts a multi-layer stacking design, combining L-shaped and circular copper busbars. Through reasonable geometric shapes and arrangement, the impedance during current conduction is minimized to the greatest extent possible. This not only improves current conduction efficiency but also effectively disperses the heat generated by the current flow, reducing the risk of local overheating. Furthermore, by adding widening members (first widening member, second widening member, third widening member) to the mounting hole positions (first mounting hole, second mounting hole, third mounting hole) on each circular busbar (first circular busbar, second circular busbar, third circular busbar), the local impedance of these key locations is effectively reduced. Due to the reduced impedance, the heat generated by the current flow is also reduced accordingly, thus reducing the risk of local overheating and thereby improving the thermal stability and service life of the entire copper busbar assembly.

[0026] like Figure 1-4 As shown, the utility model provides a technical solution: a motor slip ring copper bar group, including a copper bar component formed by overlapping and arranging a first copper bar component, a second copper bar component and a third copper bar component.

One end of the first L busbar 1 is welded to the first connecting plate 10. The first circular busbar 2 is also fixedly connected to a first connecting buckle 7. A first mounting hole 8 is provided on the first circular busbar 2. A first widening piece 9 matching the first mounting hole 8 is fixedly connected to the first circular busbar 2.

[0028] The first circular row 2 is a ring-shaped structure with an opening. The first connecting plate 10 is located on the outer wall of the first circular row 2. The first mounting hole 8 is widened on the first circular row 2 by the first widening member 9, which can effectively reduce local impedance, reduce the risk of local overheating, and extend service life.

[0029] The second copper busbar assembly includes a second L-shaped busbar 3 and a second circular busbar 4. The second circular busbar 4 is fixedly connected to a second connecting plate 13. One end of the second L-shaped busbar 3 is welded to the second connecting plate 13. The second circular busbar 4 is also fixedly connected to a second connecting buckle 18. A second mounting hole 11 is opened on the second circular busbar 4. A second widening piece 12 matching the second mounting hole 11 is fixedly connected to the second circular busbar 4.

[0030] The second circular row 4 is a ring-shaped structure with an opening. The second connecting plate 13 is located on the outer wall of the second circular row 4. The second mounting hole 11 is widened on the second circular row 4 by the second widening member 12, which can effectively reduce local impedance, reduce the risk of local overheating, and extend service life.

[0031] The third copper busbar assembly includes a third L-shaped busbar 5 and a third circular busbar 6. The third circular busbar 6 is fixedly connected to a third connecting plate 17.

[0033] The first L row 1 and the first connecting plate 10, the second L row 3 and the second connecting plate 13, and the third L row 5 and the third connecting plate 17 are all laser welded to increase the welding area, reduce the resistance at the weld, and reduce the defective rate. Laser welding has the advantages of low heat input and fast welding speed, which can effectively reduce the thermal impact on the material during the welding process and reduce the risk of deformation. During the welding process, a precise temperature control system is used to ensure that the temperature in the welding area is evenly distributed, avoiding stress concentration caused by temperature differences.
