Title:
VOLTAGE DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/065736
Kind Code:
A1
Abstract:
Provided is a voltage detection device. The device comprises a rod, a contact member and a probe. The contact member is rotatably connected to an axial end of the rod and configured to abut against an electric motor shaft, and the probe is electrically connected to the contact member. By means of rotationally connecting to a rod a contact member abutting against an electric motor shaft, the contact member can be rotated relative to the rod, and when the contact member abuts against the electric motor shaft in a rotating state, the contact member can rotate relative to the rod under the influence of the electric motor shaft, so as to change sliding friction to rolling friction between the contact member and the electric motor shaft, which significantly reduces the coefficient of friction between the contact member and the electric motor shaft, and thus reduces the wear and tear on the contact member, so that the service life of the contact member is prolonged, and thus the service life of the voltage detection device is prolonged.
