Drive device for an electrically drivable vehicle, and vehicle
A drive device for an electrically drivable vehicle includes a housing body with a first fastening device, a cover which, after release of a second fastening device interacting with the first fastening device for fastening the cover to the housing body, is movable from a first position, in which the cover covers live components of the drive device during operation of the drive device, into a second position, in which the components are exposed, and a first connection device, to which a second connection device is connectable for establishing an electrically conductive connection and/or a data connection. The first fastening device and the first connection device are arranged such that in the first position access to the second fastening means in its position fastening the cover is only possible after the second connection device has been released from the first connection device.
1. A drive device for an electrically drivable vehicle, comprising:
a housing body with a first fastening means,
a second fastening means engageable with the first fastening means,
a cover which, after release of the second fastening means interacting with the first fastening means for fastening the cover to the housing body, is movable from a first position, in which the cover covers components of the drive device during operation of the drive device, into a second position, in which the components are exposed, and
a first connection means, to which a second connection means is connectable to establish an electrically conductive connection and/or a data connection,
wherein the first fastening means and the first connection means are arranged in such a way that access to the second fastening means in the first position fastening the cover is only possible after the second connection means has been released from the first connection means.
2. The drive device according to claim 1 , wherein the first connection means has a guide for the second connection means, an imaginary extension of which covers the first fastening means.
3. The drive device according to claim 1 , wherein the first fastening means and the first connection means are each arranged on a portion of the housing body, the portions extending at right angles to one another.
4. The drive device according to claim 1 , wherein the first connection means is a socket, and/or the second connection means is a plug, and/or the first fastening means is a hole with an internal thread and/or the second fastening means is a screw.
5. The drive device according to claim 1 , further comprising a safety device which is designed to detect at least one critical state of the drive device and to trigger a safety function as a result of the detection of the critical state.
6. The drive device according to claim 5 , wherein the safety device is designed to detect a critical state if
the first and second connection means are not coupled to one another and/or
the cover is not in the first position and/or
no second fastening means interacts with the first fastening means.
7. The drive device according to claim 5 , wherein the safety function comprises discharging a capacitor of the drive device.
8. The drive device according to claim 1 , wherein the cover comprises a cover portion for covering a volume of the housing body accommodating the components and a fastening portion, which protrudes from the cover portion and on which the first and second fastening means act for fastening the cover.
9. The drive device according to claim 1 , wherein the housing body and the cover form a hinge by means of which the cover is movable from the first position into the second position by pivoting.
10. The drive device according to claim 1 , further comprising an electric machine and a power converter, wherein the components coverable by the cover comprise electrical lines which connect the electric machine and the power converter.
11. A vehicle comprising the drive device according to claim 1 .
12. The drive device according to claim 1 , wherein the second connecting means connected to the first connecting means is located above the first fastening means so that the second fastening means can be fastened to and removed from the first fastening means only when the second connecting means is removed from the first connecting means.
