Description

Technical Field

[0001] This utility model relates to the field of steering system technology, specifically to a motor test bench structure with heat dissipation function. Background Technology

[0002] During SCUA bench testing, the motor needs to operate continuously and maintain high power for extended periods, causing a significant amount of heat to accumulate in the motor windings. Higher motor temperatures lead to increased winding resistance, decreased ECU performance, and ultimately, poorer motor performance. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this utility model provides a motor test bench structure with heat dissipation function, which enables the temperature rise of the motor during the bench test process to be controlled, and greatly improves the efficiency of the bench test.

[0004] To achieve the above objectives, a motor test bench structure with heat dissipation function is designed, including a heat dissipation fin assembly. The heat dissipation fin assembly comprises an upper fin and a lower fin, which are connected by a hinge. The upper fin is composed of several fins arranged and connected, each fin being a fan-shaped thin sheet structure. The lower fin is also composed of several fins arranged and connected, each fin being a fan-shaped thin sheet structure. The fins of the upper fin and the fins of the lower fin are arranged in a staggered manner.

[0005] The length of each fin is less than 16mm.

[0006] The hinge includes a pivot and a pivot connector. The pivot connector is a three-section structure, with the pivot passing through the middle first pivot connector and connecting to the second pivot connectors on both sides.

[0007] The rotating shaft is connected to one side of the upper fin via a first rotating shaft connector in the middle; the two second rotating shaft connectors are connected to one side of the lower fin.

[0008] The rotating shaft is connected to one side of the lower fin via a first rotating shaft connector in the middle; the two second rotating shaft connectors are connected to one side of the upper fin.

[0009] The upper and lower fins are sleeved on the outside of the motor windings.

[0010] The opening and closing angle range of the upper and lower fins is 0° to 90°.

[0011] Compared with the prior art, this utility model provides a motor test bench structure with heat dissipation function, which enables the temperature rise of the motor during the bench test process to be controlled, and greatly improves the efficiency of bench test.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Taking the motor used in SCUA experiments as an example, the motor diameter is generally 92mm, and the maximum output torque can reach 8Nm. Due to the small heat dissipation size, the motor generates a lot of heat during operation, causing the motor torque to fail to reach the set value, resulting in deviations in the experiment.

[0019] Therefore, a motor test bench structure with heat dissipation function was designed, such as... Figures 1 to 4 As shown, the heat dissipation fin assembly includes an upper fin 1 and a lower fin 2, which are connected by a hinge 3. The upper fin 1 is composed of several fins arranged and connected, each fin being a fan-shaped thin sheet structure. The lower fin 2 is composed of several fins arranged and connected, each fin being a fan-shaped thin sheet structure. Each fin of the upper fin 1 and each fin of the lower fin 2 are arranged in a cross pattern.

[0020] Each fin is less than 16mm long. A numerical model analysis of the designed heat dissipation fixture revealed that a 16mm fin provides high heat dissipation efficiency without affecting the normal operation of the test bench.

[0021] The hinge 3 includes a pivot and a pivot connector. The pivot connector is a three-section type. The pivot 3-1 passes through the first pivot connector 3-2 in the middle and is connected to the second pivot connectors 3-3 on both sides.

[0022] The hinge 3 is designed as a three-section hinge with a hinge radius of 3.5mm and a pivot 3-1 length of 14mm, making the overall opening and closing of the clamp more reliable.

[0023] The upper fin 1 and the lower fin 2 have the same structure. Through the staggered design of the pivot 3-1, the first pivot connecting seat 3-2 and the second pivot connecting seat 3-3 on the hinge 3, the fins on the upper fin 1 and the lower fin 2 can be distributed in a cross manner to achieve the best heat dissipation effect.

[0024] Therefore, the hinge assemblies on the upper fin 1 and the lower fin 2 can be designed and connected as required: Option 1, the pivot 3-1 is connected to one side of the upper fin 1 through the middle first pivot connector 3-2; the two second pivot connectors 3-3 are connected to one side of the lower fin 2; Option 2, the pivot 3-1 is connected to one side of the lower fin 2 through the middle first pivot connector 3-2; the two second pivot connectors 3-3 are connected to one side of the upper fin 1.

[0025] Upper fin 1 and lower fin 2 are mounted on the outside of the motor winding.

[0026] The opening and closing angle range of the upper fin 1 and the lower fin 2 is 0°~90°.

[0027] To facilitate the opening and closing of the heat dissipation clamp, a cross-fin heat dissipation structure was designed, allowing the clamp to open and close at an angle of up to 90°, enabling quick and easy installation and disassembly.

[0028] This invention has a simple and easy-to-understand structure, making it easy to implement. Furthermore, it can be applied to other applications, such as using a forced-air cooling mechanism while employing a clamp to enhance heat convection and make the motor temperature easier to control. This structure has been successfully applied to benchtop motor operation, and the results meet the requirements.
