Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a detection device and a new energy vehicle drive motor. Background Art

[0002] The temperature of the motor affects its service life. The traditional method of detecting motor temperature is to embed the temperature sensor inside the motor and obtain the temperature parameters by direct measurement. However, this method depends on the accuracy of the temperature sensor and the motor structure, and is limited by the number and installation position of the temperature sensor, and cannot provide sufficient thermal protection for the motor.

[0003] The Chinese patent document with the existing announcement number CN113910908A discloses a new energy vehicle drive motor, and the heat dissipation of the current new energy vehicle motors mostly adopts air cooling, through a radiator (mostly a cooling fan) or directly using air cooling without a radiator, that is, dissipating the heat through the air flow when the car is running. When using the air cooling heat dissipation method, since the traditional motor temperature detection method cannot fully detect the temperature well, when the temperature distribution is uneven and the vehicle speed is high at this time, the rapid flow of air takes away a large amount of heat from the motor. Since the heating position of the motor is not consistent with the position of the temperature sensor, the temperature measured by the temperature sensor at this time is normal, but the temperature of the abnormal heating part of the motor is actually too high. Improvement and optimization are made.

[0036] A new energy vehicle driving motor includes a detection device.

[0037] The temperature detection device for automobile drive motor designed by the present invention first detects when the temperature inside the motor rises through the set temperature detection mechanism 4, and then alarms through the temperature sensor 402, and activates the telescopic control rod 403 through the control module 404 to push the heat-conducting rod 406 outward, so that the conduction plate 409 in the arc-shaped placement groove 410 is pushed out and contacts the arc-shaped conduction frame 506 set on the outside of the drive motor body 1.
