Technical Field
[0001] The utility model belongs to the technical field of motor encoder adjustment, and in particular relates to a zero-position adjustment experimental device for a motor encoder of a new energy vehicle. Background Art
[0002] The motor encoder of new energy vehicles is a sensor installed on the motor shaft. It generates an electrical signal at each position by monitoring the rotation of the shaft and transmits these signals to the motor controller.
[0003] The zero position accuracy of the motor encoder is crucial to the precise control of the motor. If the zero position of the encoder is inaccurate, it will cause deviations in the motor control and affect the vehicle's driving performance and safety. In this way, the operator is required to conduct a zero position adjustment experiment on the motor encoder of the new energy vehicle to ensure the zero position accuracy of the encoder. The oscilloscope plays an important role in this experiment. It can help the operator observe and analyze the signal waveform output by the motor encoder. Through the oscilloscope, the operator can observe the encoder's U-phase signal, Z signal, etc. in real time. The changes in these signals can reflect the relative position relationship between the encoder and the motor, so as to adjust the encoder. When the oscilloscope is in use, the oscilloscope generally dissipates heat naturally through the heat dissipation holes opened, which has a higher heat dissipation efficiency. Sometimes it is easy to cause the internal temperature of the oscilloscope to be too high, thereby affecting the normal operation of the oscilloscope and causing the experiment to be affected.

At this time, the butterfly bolt 19 is passed through the rotating plate 18 and screwed into the fixing hole 20, so that the position of the rotating plate 18 can be fixed on one side of the vertical block 14, thereby limiting the position of the transparent baffle 16 in the slide groove 15. The butterfly bolt 19 is screwed out to rotate the rotating plate 18 so that the transparent baffle 16 can slide out of the slide groove 15.

At this time, the butterfly bolt 19 is penetrated through the rotating plate 18 and screwed into the fixing hole 20, so that the position of the rotating plate 18 can be fixed on one side of the vertical block 14, thereby limiting the position of the transparent baffle 16 in the slide groove 15.
