Rail assemblies for motorized architectural coverings and related methods

An architectural covering comprising:

• a rail having a rail housing, the rail housing having an interior shape;
• a motor assembly disposed in the rail housing, the motor assembly comprising a motor housing that has an exterior shape complementing and engaging the interior shape of the rail housing;
• and
• an end cap coupled to the rail housing and the motor housing such that the end cap is in direct contact with the motor housing, the end cap comprising a first protrusion that is received in the rail housing and a second protrusion that is in engaged with a receiver formed at an end of the motor housing, the end cap capable of pivoting relative to the rail housing when the end cap is coupled to the rail housing prior to the end cap being coupled to another portion of the rail, the other portion of the rail to restrict the pivoting of the end cap when the end cap is coupled to the rail.

A rail for an architectural covering, said rail comprising:

• a first housing having an interior shape;
• a second housing including a motor, the second housing disposed in the first housing and having an exterior shape complementing and engaging the interior shape of the first housing;
• and
• an end cap coupled to the first housing and the second housing such that the end cap is in direct contact with the second housing,
• wherein the end cap comprises a first protrusion that is received in the rail housing and a second protrusion that is engaged with a receiver formed at an end of the motor housing,
• wherein the end cap is capable of at least two degrees of freedom of motion relative to the second housing prior to the end cap being coupled to the first housing, and
• wherein the first housing is to constrain the at least two degrees of freedom of motion of the end cap when the end cap is coupled to the first housing and the second housing.
