The lower portion defines an internal cavity that extends upward into the lower portion The internal cavity defines a bottom opening through which the internal cavity may be accessed.

As will be described in greater detail herein, at least a portion of the parcel carrier FIG. In the illustrated embodiment, the UAV electrical interface provides an electrical connection to a power source e. In the illustrated embodiment, the UAV chassis' upper portion , lower portion , and reduced width portion define a generally hourglass shape. Similarly, the width of the lower portion is tapered in the upward direction, such that the width of the lower portion gradually increases away from the reduced width portion As will be described in greater detail herein, the hourglass-profile of the UAV chassis enables it to engage the UAV support mechanism provided on the roof panel of the parcel delivery vehicle 10, thereby enabling takeoff from and landing on the vehicle's roof.

The UAV support mechanism may secure the UAV chassis to the vehicles roof such that the UAV chassis may remain secured to the vehicle 10 as the vehicle 10 moves. As shown in FIGS. In the illustrated embodiment, the landing gear are provided on an underside or downward- facing side of the upper portion of the UAV chassis.

In the illustrated embodiment, the landing gear comprise a pair of rollers oriented to face downward in the vertical direction. In some embodiments, the rollers of the landing gear may be powered such that the landing gear may propel the UAV chassis along the UAV support mechanism As will be described in greater detail herein, the landing gear are configured to engage opposing rails of the UAV support mechanism positioned on the vehicle 10 FIG.

In embodiments, the landing gear may be formed from a resilient material that may elastically deform when the UAV is engaged with the opposing rails of the vehicle 10 FIG.

According to various embodiments, the parcel carrier's engagement housing defines a shape that is generally complimentary and corresponds to the interior cavity of the lower portion of the UAV chassis As a result, the engagement housing may be inserted into the cavity of the lower portion of the UAV chassis in order to selectively secure the parcel carrier to the UAV as discussed further in relation to FIG.

In the illustrated embodiment, the parcel carrier's engagement housing includes a power supply configured to power the UAV and parcel carrier In particular, the power supply is configured to power the UAV and parcel carrier when the engagement housing is engaged within the inner cavity of the UAV chassis' lower portion In the illustrated embodiment, the power supply comprises a battery.

However, as will be appreciated from the description herein, the power supply may comprise any suitable device for providing electrical power to the UAV and parcel carrier e. In particular, the at least one carrier electrical interface is configured to interface with UAV electrical interface FIG. As the engagement housing , and accordingly the power supply , is removable from the UAV chassis , engagement housings with depleted power supplies may be replaced with engagement housings having charged power supplies By periodically replacing the power supply , the UAV may be provided with continuously sufficient power to perform repeated deliveries.

According to certain embodiments, as the power supply is included within the engagement housing — which is configured to be selectively coupled to a parcel FIG. In particular, in the illustrated embodiment of FIG. As discussed in greater detail herein, this leaves the engagement housing substantially unencumbered in order to permit engagement with the lower portion of the UAV housing In the illustrated embodiment, the parcel carrier is substantially symmetrical and the parcel carrying arms on the opposite sides engagement housing are substantially the same.

A plurality of pins extend inward from the parcel rails toward the parcel in the lateral direction, and are selectively positioned to engage corresponding apertures defined by the parcel FIG. Each of the parcel carrying arms are slidably coupled to the engagement housing such that the parcel carrying arms are movable in the lateral direction with respect to the engagement housing In particular, the parcel carrying arms are repositionable between an inward, engaged position e.

Alternatively, in various other embodiments, the parcel carrying arms are pivotally coupled to the engagement housing such that the parcel carrying arms are movable in the lateral direction with respect to the engagement housing , such as by pivoting about an axis that is parallel with the longitudinal direction as depicted.

In embodiments, the parcel carrying arms may be inwardly biased in the lateral direction, such that the parcel carrying arms are biased toward the parcel FIG. In this way, the parcel carrying arms may be biased into the engaged position, in which the plurality of pins are positioned within the apertures FIG.

When the engagement housing is installed to the inner cavity , the engagement housing may fit partially or entirely within the inner cavity , and once positioned within the inner cavity , may be retained within the inner cavity by the one or more retaining members The retaining members are movable with respect to the inner cavity of the UAV chassis such that each of the retaining members move inward into and outward from the inner cavity In the illustrated embodiment, the retaining member defines a sloped sidewall and an upper wall The retaining member is mounted substantially within a wall of the UAV chassis' lower portion and is configured for lateral movement relative to the wall.

In particular, the retaining member's ability to move laterally enables to extend inwardly into the lower portion's inner cavity in an extended orientation or be recessed into the lower portion wall in a retracted orientation. In this orientation, the retaining member's sloped sidewall and top wall each extend into the inner cavity When the parcel carrier's engagement housing is inserted into the UAV's inner cavity , the engagement housing will contact the retaining member's sloped sidewall and push the retaining member laterally into its retracted orientation.

Once the bottom edge of the engagement housing is inserted past the plane of the retaining member's top wall , the spring will push the retaining member back into its extended orientation. In this configuration, the retaining member will extend back into the inner cavity such that the engagement housing's bottom edge rests on the retaining member's top wall , thereby securing the engagement housing within the UAV chassis' inner cavity When the engagement housing is to be released from the UAV chassis , the UAV control system actuates the solenoid , which is configured to push the retaining member in a lateral direction back into its retracted orientation overcoming the force of the biasing spring This movement retracts the retaining member's top wall into the wall of the UAV chassis' lower portion , leaving the engagement housing an unobstructed path to be disengaged from the lower portion's inner cavity According to various embodiments, a plurality of retaining member assemblies of the type shown and described in relation to FIG.
