Abstract
A ground structure of a driving motor applied to an eco-friendly vehicle includes a rotation shaft rotatably supported by a bearing, a motor housing enveloping the bearing and the rotation shaft, a ground structure disposed in a direction in which the rotation shaft extends, and a cover having the ground structure installed therein and connected to the motor housing. In particular, the ground structure contacts the rotation shaft through a ground unit, thereby grounding the rotation shaft.
Claims11
A ground structure of a driving motor applied to an eco-friendly vehicle, the ground structure comprising:
- a rotation shaft rotatably supported by a bearing;
- a motor housing enveloping the bearing and the rotation shaft;
- a ground structure disposed in a direction in which the rotation shaft extends;
- and
- a cover having the ground structure installed therein and connected to the motor housing,
- wherein the ground structure is configured to contact the rotation shaft through a ground unit, thereby grounding the rotation shaft,
- wherein the ground structure further comprises:
- a ground housing connected to the cover, wherein the ground unit is extended from an inside of the ground housing and configured to contact the rotation shaft;
- and
- a spring fixedly coupled inside the ground housing and electrically connected to the ground unit, and
- wherein:
- the ground structure further comprises a ground plate disposed between the ground unit and the spring,
- the ground unit is configured to rotate according to a rotation of the rotation shaft, and
- the ground plate is configured to contact the ground unit and prevent the spring from being damaged due to the rotation of the ground unit.
