Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle components, and more specifically, to a new energy vehicle drive motor position sensor. Background Art

[0002] The most widely used type of automotive drive motor position sensor is the resolver, or resolver sensor for short. Its structure and working principle are as follows: In the drive motor, the resolver includes a drive coil and two driven coils. The cosine winding senses the magnetic field of the excitation winding and generates a cosine signal. The resolver utilizes the basic relationship between magnetism and electricity, especially Ampere's law and Faraday's law of electromagnetic induction. These principles enable the resolver to accurately sense the position and speed of the motor rotor, providing key information for the drive control of electric vehicles.

[0003] Existing new energy vehicle drive motor position sensors detect the position of the rotor inside the motor. Multiple sensors are often set up to expand the spatial coverage. Some sensors can detect places that other sensors cannot detect, thereby increasing the system's monitoring capabilities and detection probability. This helps to more fully understand the motor's operating status and position information, but because the position of the sensor is fixed, even if multiple sensors are installed, there may still be certain areas or angles that cannot be effectively monitored due to their fixed positions, forming the so-called "blind spots". This may result in failures or changes in these areas not being detected in a timely manner. For this reason, we propose a new energy vehicle drive motor position sensor. Utility Model Content

[0022] The working principle and use process of this utility model:

[0023] The motor rotor is installed in the spline sleeve 4, and the position of the motor rotor is detected by setting a plurality of sensors 9. By detachably installing the connecting block 10 in the slot 6, on the one hand, different numbers of sensors 9 can be selected and used according to the detection requirements to meet the detection requirements. On the other hand, the installation position of the sensor 9 can be adjusted according to the detection requirements. The sensor 9 is installed in the slot 6 at different positions. By adjusting the number and position of the sensors, it can be ensured that each key position of the motor rotor can be accurately monitored.

The present application can flexibly adjust the position and number of sensors according to the specific operating requirements of the motor and the design requirements of the vehicle to optimize the performance of the system.

By setting a detachable connection mode between the second connection sleeve 15 and the interface 20, when a component inside the sensor is damaged or needs to be repaired, the detachable connection mode allows engineers or technicians to easily remove the second connection sleeve 15 from the interface 20, so as to conveniently repair or replace the damaged component. This greatly shortens the maintenance time and improves the maintenance efficiency. The elastic force of the spring 19 drives the pressure block 17 to press on the conductor 16, which can fix and limit the conductor 16 and improve the firmness of the connection between the conductor 16 and the interface 20.
