DETAILED DESCRIPTION
The present disclosure relates to a mobile storage unit that is decoupled from the delivery truck or trailer. By decoupling the storage from the delivery truck, the sortation and loading of delivery items may be made while the delivery truck or trailer is remotely located. Thus, the delivery vehicle may make deliveries while the mobile storage unit is being loaded with items for the next trip of the delivery vehicle. Additionally, some delivery items may require refrigeration. The mobile storage units may function as refrigerators or freezers. This allows for rapidly scaling a delivery fleet with a combination of mobile storage units, some of which may provide refrigeration.
According to various embodiments, a payload platform of a delivery vehicle may be configured to receive multiple mobile storage units. This allows for multiple storage units to be loaded with delivery items at separate locations within a materials handling facility. In some embodiments, the mobile storage units may include a set of wheels to facilitate efficient transportation throughout a large warehouse of items scheduled for delivery. The payload platform of a truck or trailer may receive a combination of refrigerated mobile storage units and non-refrigerated storage units. By allowing the delivery vehicle to include refrigerated and non-refrigerated items, delivery route optimization may occur.
Moreover, some embodiments of the present disclosure relate to including a display monitor and computing device in a mobile storage unit. In this case, a mobile storage unit may track those items stored in the mobile storage unit and provide information to delivery vehicle operators via a display monitor. This information may include delivery information such as delivery route information, mobile unit storage temperature, or any other information relating to the delivery of items. In the following discussion, a general description of the system and its components is provided, followed by a discussion of the operation of the same.
With reference to FIG. 1, shown is a non-limiting example of a top view of a payload platform 100 of a motorized vehicle, such as a truck, according to various embodiments of the present disclosure. The payload platform 100 may be mounted or permanently attached to the cabin of a motorized vehicle such as, for example, a delivery truck. In this respect, the payload platform 100 may form a flat bed or flat surface that extends from a delivery vehicle cabin.
In other embodiments, the payload platform 100 may be a trailer that is configured to be towed by a motorized vehicle. In this case, the payload platform 100 is attached to a vehicle cabin 103 that comprises a motor to move the payload platform 100. The payload platform 100 may be supported by one or more wheels 106. The payload platform 100 may include one or more support areas 109a,b,c. The non-limiting example of FIG. 1 depicts three support areas 109a,b,c made up of a first support area 109a, a second support area 109b, and a third support area 109c. Although FIG. 1 depicts three support areas 109a,b,c, the payload platform 100 may be configured with any number of support areas 109a,b,c. A support area 109a,b,c may form a horizontal surface that is configured for the placement of a mobile storage unit, as is discussed below with respect to at least FIG. 9. According to an embodiment, the payload platform 100 is a relatively flat region that is configured to support a loading of a mobile storage unit.
According to various embodiments, the payload platform 100 includes one or more receiving guiderails 112a-f to allow a mobile storage unit to slide into a position defined by the placement of the receiving guiderail 112a-f. A guiderail may include a channel formed by a pair of opposing walls or opposing fins. The receiving guiderail 112a-f functions as an extended receptacle that receives a component by forcing the component to slide along the axis of the receiving guiderail 112a-f. As shown in the non-limiting example of FIG. 1, the receiving guiderail 112a-f may be aligned in a parallel manner with respect to one another. The receiving guiderail 112a-f may be used in conjunction with a receiving locking device such as a lever, pin, latch, magnet, clip, hook, buckle, or any other fastener that is configured to receive a corresponding component that is attached to the mobile storage unit and lock the corresponding component into place. The receiving locking device may be attached to the receiving guiderail 112a-f or attached to a support area 109a-c. The receiving locking device may be a manual lock used to fasten the load by hand. The receiving locking device may also be electronically controlled such that the locking mechanism of the receiving locking device is automatically actuated in response to receiving a remote electronic communication signal.
In some embodiments, the receiving guiderails 112a-f include one or more wheels or bearings disposed in the channel formed by the receiving guiderail 112a-f. The wheels or bearings facilitate linear motion for any load placed in contact with the wheels or bearings.
A receiving guiderail 112a-f may be disposed, mounted, attached, or otherwise fastened to a respective support area 109a,b,c. For example, a first support area 109a may include a first receiving guardrail 112a and a second receiving guardrail 112b. The second support area 109b may include a third receiving guardrail 112c and a fourth receiving guardrail 112d.
