Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts manufacturing, in particular to an oil tank structure of a new energy rotor bracket. Background Art

[0002] With the popularization and promotion of new energy vehicles, new impacts and challenges have been brought to the traditional automotive parts processing field. Due to the technical characteristics of new energy vehicles, the types and performance of parts required are different from those of traditional vehicles. For example, the demand for core components of new energy vehicles such as batteries, motors, and electronic controls will increase significantly. In order to adapt to the needs of new energy vehicles, automotive parts companies, especially those supporting traditional fuel engines, need to continuously improve and innovate technology to seize new market opportunities.

[0003] Automobile motors generate a lot of heat during operation. In order to ensure the working performance of automobile motors, they need to be evenly cooled. Currently, automobile motor rotor cooling structures generally include air cooling, water (coolant) cooling, and oil cooling.

[0004] Among them, although the air cooling has a relatively simple implementation structure, it has obvious disadvantages in terms of heat dissipation efficiency, noise, heat dissipation area, and the influence of ambient temperature. Although the water cooling system has advantages such as good heat dissipation effect and is suitable for high-power motors, it also has disadvantages such as complex structure, great environmental influence, risk of coolant leakage, insulation problems, and high cost and maintenance costs. Oil cooling technology has the advantages of excellent heat dissipation effect, high insulation and stability, low failure rate, strong applicability, and high cost-effectiveness. These advantages have made oil cooling technology widely used and recognized in high-performance and high-power motor applications.

[0005] Setting oil hole cooling on the side wall of the motor rotor bracket is a common and effective cooling method. The cooling oil enters the oil hole on the side wall of the motor rotor bracket through a special oil circuit, and then flows into the cooling oil circuit inside or around the rotor. The cooling oil flows in the cooling oil circuit inside or around the rotor, taking away the heat generated by the rotor, and flows out of the motor through the oil outlet to form a cycle. However, the design of the opening on the side wall of the bracket will increase the cost of bracket processing and manufacturing, and will affect the overall strength of the bracket to varying degrees, thereby affecting the stability of motor use. Utility Model Content

[0006] The utility model aims to provide an oil groove structure of a new energy rotor bracket, aiming to solve the problem that the oil holes are arranged on the side walls of the existing motor rotor bracket, which will affect the overall strength of the bracket and thus affect the stability of the motor.

[0007] To achieve the above-mentioned purpose, in a first aspect, the utility model provides a new energy rotor support oil tank structure, including a motor rotor support, an input shaft and a magnetic ring;

[0008] The input shaft is arranged on one side of the motor rotor bracket, the magnetic ring is arranged outside the motor rotor bracket, the motor rotor bracket has an oil groove and an axial oil hole, the oil groove is located on one side of the motor rotor bracket, and the axial oil hole is located in the oil groove.

[0009] Among them, there are 6 oil grooves.

[0010] Among them, there are 6 axial oil holes.

[0011] In a second aspect, the present invention also provides a method for processing and forming an oil groove structure of a new energy rotor bracket, including the following steps:

[0012] Place the motor rotor bracket in the forming female die of the oil groove forming die;

[0013] The press drives the pressure plate to press the motor rotor bracket tightly;

[0014] Move the motor rotor bracket to contact the forming male die until the oil groove forming is completed.

[0015] Among them, the oil groove forming die includes a forming female die, a pressure plate, an outer forming female die and a forming male die. The pressure plate is arranged on one side of the outer forming female die, the forming female die is arranged on one side of the outer forming female die, and the forming male die is arranged on one side of the pressure plate.

[0016] For the oil groove structure of a new energy rotor bracket of the present invention, under the action of the cooling oil supply system, the cooling oil cools the rotor assembly inside the motor rotor bracket, and then passes through the axial oil hole of the motor rotor bracket. And under the action of the oil groove structure with a predetermined depth, the input shaft is used to transmit the kinetic energy of the motor, so that the motor rotor bracket rotates to throw out the cooling oil, which can effectively transport the cooling oil to the magnetic ring and other working components, thereby realizing the effective cooling of these components, improving the cooling efficiency. The oil groove also plays the role of a reinforcing rib in the overall structure of the motor rotor bracket, which also plays a certain role in improving the strength of the part, enhancing the product reliability, and solving the problem that setting oil holes on the side wall of the existing motor rotor bracket will affect the overall strength of the bracket, thereby affecting the use stability of the motor.
