Description

Technical Field

[0001] This utility model relates to the field of new energy electric drive excitation system technology, and in particular to a brush holder assembly for a new energy electric drive excitation system. Background Technology

[0002] New energy electric drive excitation refers to a device that uses new energy sources (such as wind energy and solar energy) to provide power to a motor and converts mechanical energy into electrical energy through the principle of electromagnetic induction. Its core lies in providing a stable magnetic field to the motor rotor through an external energy drive system, thereby achieving efficient energy conversion.

[0003] New energy electric drive excitation brush holders are widely used in new energy equipment such as electric vehicles and wind power generation. With the continuous development of new energy technology, traditional excitation brush holders have problems such as complex structure, frequent maintenance, and short service life. They are time-consuming and laborious to replace, and are inconvenient for people to use.

[0004] Therefore, it is necessary to provide a new brush holder assembly for a new energy electric drive excitation system to solve the above problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a brush holder assembly for a new energy electric drive excitation system that is reasonably designed, easy to maintain, and has a long service life.

[0006] To solve the above-mentioned technical problems, the brush holder assembly of the new energy electric drive excitation system provided by this utility model includes: a mounting plate, on both sides of the mounting plate, a plurality of brush boxes are mounted on the side wall of the conductive plate, and carbon brushes are slidably connected to the inside of the brush boxes and the side wall of the conductive plate; a plurality of coil springs are mounted on the side wall of the conductive plate, and the coil springs abut against one side of the carbon brushes; carbon brush wires are mounted on the surface of the carbon brushes, and one end of the conductive carbon brush wires is welded to the surface of the conductive plate.

[0007] Preferably, the surface of the mounting plate has a triangular structure, and mounting posts are installed at the corners of the mounting plate.

[0008] Preferably, the shortest vertical distance between one side of the mounting column and the mounting plate is significantly different from the shortest vertical distance between the other side of the mounting column and the mounting plate.

[0009] Preferably, the carbon brush is slidably connected to the surface of the motor shaft, the end of the carbon brush that contacts the motor shaft has an arc-shaped structure, and the motor shaft passes through the mounting plate.

[0010] Preferably, the carbon brushes located on both sides of the mounting plate are staggered.

[0011] Preferably, a plurality of limiting blocks are installed on the side wall of the mounting plate, and the limiting blocks abut against the side wall of the carbon brush wire.

[0012] Compared with related technologies, the brush holder assembly of the new energy electric drive excitation system provided by this utility model has the following beneficial effects:

[0013] This utility model provides a brush holder assembly for a new energy electric drive excitation system. The mounting plate, conductive plate, and brush box are arranged in a stepped, layered layout. Through the precise structural design of the mounting plate and brush box, the overall height is reduced, adapting to the confined space inside the motor of the new energy electric drive excitation system, minimizing interference with surrounding components, and enabling rapid installation and maintenance. A high-elasticity disc spring provides constant pressure, ensuring the reliability of dynamic contact between the carbon brush and the motor shaft, reducing wear and sparking. The large contact surface between the conductive plate and the carbon brush improves conductivity, suppresses temperature rise, and extends the service life of the carbon brush. Multiple mounting posts are installed on the side wall of the mounting plate. The shortest vertical distance between one side of each mounting post and the mounting plate differs significantly from the shortest vertical distance between the other side of each mounting post and the mounting plate. The mounting posts are designed to prevent incorrect mounting, using visual or tactile feedback to ensure the correct orientation of the device, guaranteeing unique installation to the motor shaft and accelerating installation efficiency.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please see Figures 1 to 3 , Figure 1 A schematic diagram of a preferred embodiment of the brush holder assembly of the new energy electric drive excitation system provided by this utility model; Figure 2 for Figure 1 The diagram shows the front structure of the mounting plate. Figure 3 for Figure 1The diagram shows the back structure of the mounting plate. The brush holder assembly of the new energy electric drive excitation system includes: a mounting plate 1, with conductive plates 3 mounted on both sides of the mounting plate 1; multiple brush boxes 6 mounted on the side walls of the conductive plates 3; carbon brushes 7 slidably connected to the interior of each brush box 6 and the side walls of the conductive plates 3; multiple coil springs 4 mounted on the side walls of the conductive plates 3, with each coil spring 4 abutting against one side of the carbon brushes 7; and carbon brush wires 8 mounted on the surface of each carbon brush 7, with one end of the conductive carbon brush wire 8 welded to the surface of the conductive plate 3. The mounting plate 1, the conductive plate 3, and the brush box 6 are arranged in a stepped layered layout. Through the precise structural design of the mounting plate 1 and the brush box 6, the overall height is reduced, adapting to the narrow space inside the motor, reducing interference with surrounding components, and enabling quick installation and maintenance. The highly elastic disc spring 4 provides constant pressure to the carbon brush 7, ensuring the reliability of the dynamic contact between the carbon brush 7 and the motor shaft 5, reducing wear and spark generation. Furthermore, the large contact surface between the conductive plate 3 and the carbon brush 7 improves conductivity, suppresses temperature rise, and extends the service life of the carbon brush.

[0020] The surface of the mounting plate 1 has a triangular structure to increase its stability during use. Mounting posts 2 are installed at the corners of the mounting plate 1, and bolts are used to pass through the mounting posts 1 to fix the mounting plate 1 to the motor equipment, facilitating installation and disassembly and enabling maintenance personnel to operate it conveniently.

[0021] The shortest vertical distance between one side of the mounting post 2 and the mounting plate 1 is significantly different from the shortest vertical distance between the other side of the mounting post 2 and the mounting plate 1. The mounting post 2 is designed to prevent mistakes, using visual or tactile feedback to ensure the correct orientation of the device, guaranteeing the uniqueness of the installation with the motor shaft, and accelerating installation efficiency.

[0022] The carbon brush 7 is slidably connected to the surface of the motor shaft 5. The end of the carbon brush 7 that contacts the motor shaft 5 has an arc-shaped structure, and the motor shaft 5 passes through the mounting plate 1. In order to increase the contact area between the carbon brush 7 and the motor shaft 5, and to enable the carbon brush 7 to be responsible for the transmission of current and signals between the carbon brush 7 and the motor shaft 5.

[0023] The carbon brushes 7 located on both sides of the mounting plate 1 are staggered so that the carbon brushes 7 can contact the motor shaft 5 from different directions and angles, which facilitates the transmission of current and signals.

[0024] Multiple limiting blocks 9 are installed on the side wall of the mounting plate 1, and the limiting blocks 9 abut against the side wall of the carbon brush wire 8. In use, the limiting blocks 9 abut against the carbon brush wire 8, causing the elastic carbon brush wire 8 to press the carbon brush 7 towards the inside of the brush box 6, ensuring the reliability of the dynamic contact between the carbon brush and the motor shaft. The conductive plate 3 and the carbon brush 7 are also connected through the carbon brush wire 8, which facilitates the transmission of current and signals between the conductive plate 5 and the carbon brush 7.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
