Locking cap for a fluid reservoir

摘要

A locking assembly includes a release mechanism and a cap. The release mechanism includes a pin. The cap threadingly engages with a fill neck and includes a barrel portion and an engagement portion. The engagement portion radially surrounds the barrel portion. The engagement portion presents engagement threads which threadingly engage with threads of the fill neck. The annular cover portion radially surrounds the engagement portion. The annular cover portion rotates relative to the annular engagement portion in a second rotational direction to cause rotation of the engagement portion in the second rotational direction such that the engagement threads remain threadingly engaged with the neck threads. The annular cover portion rotates in the second rotational direction and causes rotation of the engagement portion in the second rotational direction to threadingly disengage the engagement threads from the threads when the pin is attached to the locking cap.

主权项

1. A vehicle comprising:
a body component; a rechargeable energy storage system (RESS); an electric traction motor that is electrically connected to the RESS, and that is configured to provide an output torque for propelling the vehicle using electrical energy from the RESS; a coolant reservoir configured to retain a fluid therein; wherein the coolant reservoir includes a fill neck having threads; wherein the coolant reservoir is in fluid communication with the RESS; a cap threadingly engageable with the fill neck of the coolant reservoir, wherein the cap includes:
an annular barrel portion axially disposable in the fill neck of the coolant reservoir;an annular engagement portion radially surrounding the annular barrel portion;wherein the annular engagement portion presents engagement threads threadingly engageable with the threads of the fill neck;an annular cover portion radially surrounding the annular engagement portion;wherein the annular cover portion is configured to rotate in a first rotational direction and cause rotation of the engagement portion in the first rotational direction such that the engagement threads threadingly engage with the threads;wherein the annular cover portion is configured to rotate relative to the annular engagement portion in a second rotational direction to cause rotation of the engagement portion in the second rotational direction such that the engagement threads remain threadingly engaged with the threads when a release mechanism is detached from the cap; andwherein the annular cover portion is configured to rotate in the second rotational direction and cause rotation of the engagement portion in the second rotational direction such that the engagement threads threadingly disengage from the threads in response to attachment of the release mechanism to the locking cap.
