DETAILED DESCRIPTION

This disclosure details a cargo bed for a vehicle. The cargo bed can transition back-and-forth between a standard bed position and an extended bed position. The cargo bed in the extended bed position provides cargo bed access openings in a least one side wall of the cargo bed. A user can utilize the cargo bed access openings to access cargo stored at a front of the cargo bed, for example.

With reference to FIG. 1, a vehicle 10 includes a passenger compartment 14 and a cargo bed 18 that is aft the passenger compartment 14 along a longitudinal axis A of the vehicle 10.

In the exemplary embodiment, the vehicle 10 is a pickup truck. The vehicle 10 could be another type of vehicle in another example, such as a car, van, sport utility vehicle, etc. The vehicle 10 has a unibody architecture. In another embodiment, the vehicle 10 could have a body-on-frame architecture.

The example vehicle 10 is an electrified vehicle. In particular, the vehicle 10 is a battery electric vehicle. In another example, the vehicle 10 could be another type of electrified vehicle, such as a plug-in hybrid electric vehicle (PHEV), or a conventional vehicle.

The example vehicle 10 includes an electrified powertrain capable of applying a torque from an electric machine (e.g., an electric motor) to drive a pair of wheels 22. The vehicle 10 can include a traction battery pack, which powers the electric machine and, potentially, other electrical loads of the vehicle 10. The powertrain of the vehicle 10 may electrically propel the wheels 22 either with or without the assistance of an internal combustion engine.

FIG. 1 shows the cargo bed 18 in a standard bed position. The cargo bed 18 can be transitioned from the standard bed position of FIG. 1 to the extended bed position of FIG. 2. The cargo bed 18 includes an extended area 20 when in the extended bed position. In the extended bed position, the cargo bed 18 can transport more cargo or larger cargo.

The cargo bed 18 includes a floor assembly 30, a front wall 34, a first side wall assembly 38D, a second side wall assembly 38P, and a tailgate assembly 42. The first side wall assembly 38D and the second side wall assembly 38P are each configured to transition back-and-forth between a standard wall position as shown in FIG. 1 and an extended wall position as shown in FIG. 2. The first side wall assembly 38D and the second side wall assembly 38P are parts of a cargo bed system that enables the cargo bed 18 to be transitioned back-and-forth between the standard bed position of FIG. 1 and the extended bed position of FIG. 2.

In this example, the first side wall assembly 38D and the second side wall assembly 38P each include an extendable wall section 50 and a fixed side wall section 54. The extendable wall sections 50 can extend and retract relative to the respective fixed side wall sections 54. The extendable wall sections 50 are retracted when the cargo bed 18 is in the standard bed position. The extendable wall sections 50 are extended when the cargo bed 18 is in the extended bed position.

The floor assembly 30 includes an extendable floor portion 60 and a fixed floor portion 64. The extendable floor portion 60 can extend and retract to transition the floor assembly 30 back-and-forth between a standard floor position and an extended floor position. The floor assembly 30 is in the standard floor position with the extendable floor portion 60 retracted when the cargo bed 18 is in the standard bed position. The floor assembly 30 is in the extended floor position with the extendable floor portion 60 extended when the cargo bed 18 is in the extended bed position.

In the exemplary embodiment, the cargo bed 18 relies on one or more actuators 70 to move the cargo bed 18 back-and-forth between the standard bed position and the extended bed position. The actuators 70 could be screw-driven linear actuators, for example. The actuators 70 could extend and retract in response to command from a button on the vehicle 10 or an input from a handheld device, such as a smartphone. In another example, the user manually moves the cargo bed 18 back-and-forth between the standard bed position and the extended bed position by sliding the cargo bed 18.

In the exemplary embodiment, the actuators 70 extend to extend the extendable wall sections 50. The extendable floor portion 60 is directly connected to the extendable wall sections 50 and is thus pulled by the extendable wall sections 50 to extend the extendable floor portion 60.

The extendable wall sections 50 each include an upper side wall 80, a core section 84, and a taillight 88. The upper side wall 80 extends along an upper edge 90 of the fixed side wall section 54 from the taillight 88 to the front wall 34.

Extending the extendable wall sections 50 moves the upper side wall 80 away from the front wall 34 to provide cargo bed access openings 92 within the first and second side wall assemblies 38D, 38P. A user 96 can access the cargo bed 18 using the cargo bed access openings 92. The user 96 can use the cargo bed access openings 92 to load cargo into to a forward area of the cargo bed 18 without climbing into the cargo bed 18, for example.

Each example cargo bed access opening 92 open vertically upwards. The front wall 34 provides a front side of the cargo bed access opening 92, the upper side wall 80 provides a rear side, and the fixed side wall section 54 provides a bottom side. In other examples, the cargo bed access openings 92 could be located further rearward and spaced from the front wall 34. For example the fixed side wall section 54 could including a portion that extends vertically upward in front of the wheels. The upper side walls 80 are shorter than what is shown in the figures. Extending the extendable wall sections 50 still reveals a cargo bed access opening, but that opening is further rearward and aft of the portion that extends vertically upward in front of the wheels 22. This cargo bed access opening could be located near the leader line associated with reference number 80 in FIG. 2.

The upper side wall 80 is slidable coupled to the fixed side wall section 54. The upper side wall 80 can include a rail that is received within a groove 98 of the fixed side wall section 54, for example.

The core section 84 is the portion of the extendable wall section 50 that is received within the fixed side wall section 54 when the first and second side wall assemblies 38D, 38P are in the standard wall position. In this example, the core sections 84 of the extendable wall sections 50 are telescopically received within the respective fixed side wall sections 54. The core section 84 can include a cargo holding surface 100. Side wall cargo 104, such as tools and other accessories, can be coupled to the cargo holding surface 100. The side wall cargo 104 could rest on the cargo holding surface 100 or could hang from the cargo holding surface 100.

When the extendable wall sections 50 are extended, the side wall cargo 104 can be accessed. When the extendable wall sections 50 are extended, a cover could be used to conceal and secure the side wall cargo 104. Instead or additionally, the side wall cargo could couple to a cargo holding surface that faces into the cargo bed 18. A tonneau cover could then cover the cargo bed 18 to secure that side wall cargo 104. When the extendable wall sections 50 are retracted, the side wall cargo 104 are received within the respective fixed side wall section 54, which secures and protects the side wall cargo 104.

The example first side wall assembly 38D and second side wall assembly 38P thus include storage areas that can be accessed by extending the respective extendable wall section 50. The extendable wall sections 50 could be locked when retracted to prevent unauthorized access to the side wall cargo 104 that is coupled to the cargo holding surface 100.

The taillight 88 is part of the extendable wall section 50. The taillight 88 extends and retracts with the extendable wall section 50. The taillight 88 is operational when the extendable wall section 50 is extended. Thus, there may be no need to add additional lighting when operating the vehicle 10 with extendable wall section 50 extended as shown in FIG. 2 and the cargo bed 18 in the extended bed position. Sensors could also be included within the extendable wall section 50. The sensors could operable with the extendable wall section 50 extended and retracted.

In the exemplary embodiment, the first side wall assembly 38D includes a grab handle 106 that can be actuated to release the extendable wall section 50 of the first side wall assembly 38D so that the extendable wall section 50 of the first side wall assembly 38D can extend relative to the fixed side wall section 54. Another grab handle can additionally or instead be included within the extendable wall section 50 of the second side wall assembly 38P.

In this example, the tailgate assembly 42 can pivot from the closed position of FIGS. 1 and 2 to the open position of FIG. 3. The tailgate assembly 42 has an inner side 112 that faces the front wall 34 of the cargo bed 18 when the tailgate assembly 42 is in the closed position of FIGS. 1 and 2. The tailgate assembly 42 is configured to pivot from the closed position of FIGS. 1 and 2, past an open position where the inner side 112 is oriented horizontally and aligned with a floor 116 of the cargo bed 18, to the open position shown in FIG. 3 where the inner side 112 is angled downward from the floor 116 of the cargo bed 18. In some examples, the tailgate assembly 42 contacts ground when in the position of FIG. 3. Vertical and horizontal, for purposes of this disclosure, are with reference to ground and a general orientation of the vehicle 10 during ordinary operation.

The tailgate assembly 42 includes a step 120 within the inner side 112. The user can use the step to assist when entering the cargo bed 18. The step 120 can be a recessed area within the inner side.

An adjustment method for the cargo bed 18 can include transitioning a side wall assembly 38D of a cargo bed 18 from a standard wall position to an extended wall position by extending an extendable wall section 50 of the side wall assembly 38D relative to a fixed side wall section 54 of the side wall assembly 38D. Extending the extendable wall section 50 can move the cargo bed 18 to an extended bed position. Extending the extendable wall section 50 can also provide a cargo bed access opening 92 in the side wall assembly 38 that the user 96 can use to access cargo within the cargo bed 18.

The preceding description is exemplary rather than limiting in nature. Variations and modifications to the disclosed examples may become apparent to those skilled in the art that do not necessarily depart from the essence of this disclosure. Thus, the scope of protection given to this disclosure can only be determined by studying the following claims.
