Title: Adaptable storage

Description:
TECHNICAL FIELD 
     The present disclosure relates to adaptable storage for vehicles and particularly, but not exclusively, to an adaptable storage compartment for vehicles. Aspects of the invention relate to an adaptable storage compartment for vehicles which is operable to partially obstruct the rear opening of a vehicle and an adaptable storage compartment for vehicles with an adaptable base. Aspects of the invention relate to a load floor assembly, to a storage compartment, to a vehicle and to a controller. 
     BACKGROUND 
     It is known to provide vehicles with two-part rear doors, which is also known as a split tailgate. A two-part rear door is normally split horizontally at a convenient vertical position of the door, for example at or just below the intersection between the rear windscreen and solid section. 
     The main purpose of a split tailgate is to facilitate opening of the rear door, for example where the rear door would otherwise be large and cumbersome. Split tailgates also enable easy access to the rear of the vehicle, for example by enabling the upper portion of the door to be opened while leaving the lower portion of the door in place. This can be useful, for example where loose items are on the load floor of the vehicle adjacent the rear door and would otherwise fall out of the vehicle if the door was opened entirely. Opening the lower portion of the door provides full access to the rear of the vehicle, aids loading of large items by acting as an extended load floor and can also be used as a seat when the vehicle is parked. 
     Developments in vehicle design, for example component and assembly weight reduction and power-assisted opening of rear doors, have resulted in a move towards more single-piece tailgates or doors, particularly given their reduced parts complexity as compared to split tailgates. However, it would be desirable to retain the secondary benefits of split tailgates with the use of single-piece doors. 
     It is a non-exclusive aim of the present invention to provide an arrangement that offers at least some of the benefits of split tailgates for use in vehicles having a single-piece rear door.

     DETAILED DESCRIPTION 
     A vehicle  1  in accordance with an embodiment of the present invention is described herein with reference to  FIGS. 1 to 6 . 
     The vehicle  1  includes a storage compartment  10 , a rear opening  11  and a rear door  12  for selectively closing the opening  11 . The rear door  12  includes an outer surface  12   a  and an inner surface  12   b  defining in part the storage compartment  10 . The storage compartment  10  includes a load floor assembly  2  incorporating a load floor  20  and a platform  3  hinged to a frame  4  adjacent the outer end or edge of the load floor  20  and inboard of the opening  11 . In this embodiment, the platform  3  is deployed and retracted by an actuation means in the form of an actuation mechanism  5 . The platform  3  is movable between a retracted or upright position (shown in  FIGS. 1 and 3 ), in which the platform  3  is vertical and obstructs part of the opening, and a deployed position (shown in  FIGS. 2 and 4 ) in which the platform  3  extends horizontally out of the opening  11  and provides an extension to the load floor  20 . In the deployed position, the load floor  20  and the platform  3  provide a substantially planar surface. This is advantageous for loading and unloading goods through, for example, sliding goods from/to the load floor  20  from/to the platform  3 . The vehicle  1  also includes a tether or cable stay  6  for supporting the platform  3  when it is in the deployed position. 
     The storage compartment  10  is also defined by the load floor  20 , opposed sides  13  and a roof (not shown). In this embodiment, the frame  4  includes a horizontal base support structure  40  on which the load floor  20  is secured and supported, a pair of opposed uprights  41 . In this embodiment, the vehicle  1  includes a downwardly angled lip  42  that extends from a rear or outer edge of the load floor  20 , when the load floor  20  is installed in the vehicle  1 , and defines the lower edge of the opening  11 . It is also envisaged that in other embodiments the lip  42  may form part of the frame  4 . The base support structure  40  includes four semi-circular hinge blocks  70 , one on either side of the center of the rear edge of the load floor  20  and one adjacent each outer end thereof. The hinge blocks  70  have substantially the same width, each including a central hole within which is received an elongate hinge rod  71 . 
     The uprights  41  are adjacent the rear of the vehicle  1  and extend part way up each of the sides  13  of the vehicle  1 . Each upright  41  includes an anchor point  43  secured to an intermediate portion thereof to which a first looped end of the tether  6  is pivotally connected. The door  12  is hinged along a horizontal axis to the top of the opening  11  and engages with a lock feature  44  accessible through a hole in the center of the lip  42 . Each upright  41  also includes an input panel  45  with a pair of input buttons in this embodiment. 
     As shown in  FIGS. 3 to 5 , the platform  3  is hollow with a ribbed internal support structure  30  over which is secured an outer skin  31 . The support structure  30  includes five hinge blocks  72  at a lower edge thereof. The hinge blocks  72  of the support structure  30  are received between the hinge blocks  70  of the base structure  40  and include central holes that are aligned coaxially with those of the hinge blocks  70  of the base structure  40  with the hinge rod  71  extending therethrough. The three internal hinge blocks  72  of the support structure  30  also span the space between adjacent hinge blocks  70  of the base structure  40  with the two outer hinge blocks  72  being located on either side thereof such that together the hinge blocks  70 ,  72  and the rod  71  provide a substantially uninterrupted hinge  7 . 
     The platform  3  also includes a retraction means in the form of a retraction mechanism  32  within an upper portion at each lateral side thereof. Each retraction mechanism  32  in this embodiment is in the form of a sprung reel that is biased to rotate in a clockwise direction as shown in the Figures. Each tether  6  is secured at its second end to the reel of the retraction mechanism  32  and is wound around the reel in the retracted or upright position shown in  FIG. 3 . 
     As shown more clearly in  FIG. 5 , the tether  6  unwinds against the spring bias of the reel of the retraction mechanism  32  as the platform  3  moves from the retracted position to the deployed position. In this embodiment, the tether  6  is unwound fully in the deployed position and is tensioned when a load is applied to the platform  3 , thereby supporting the platform  3  in this configuration. It will be appreciated that the retraction mechanism  32  may be omitted or incorporated within or mounted to the uprights  41  instead of being included within the platform  3 . 
     The actuation mechanism  5  includes an actuator  50  and a lever arm  51  connecting the actuator  50  to the platform  3 . The lever arm  51  is substantially crescent shaped member with a first of its ends fixed to the internal support structure  30  of the platform  3  adjacent, but spaced upwardly from the hinge blocks  72  to provide a predetermined movement ratio and mechanical advantage. In this embodiment, the actuator  50  is an electromechanical linear actuator  50  that includes a cylinder  52  and a piston  53  that extends and retracts telescopically with respect to the cylinder  52 . The free end of the cylinder  52  is pivotally mounted to the underside of the base support structure  40 , while the free end of the piston  53  is pivotally mounted to a second, free end of the lever arm  51 . It will be appreciated that several other actuation mechanisms  5  are envisaged without departing from the scope of the invention, for example the actuator may comprise a rotary actuator and/or may be connected directly to the platform or by a linkage with more than one element and/or may be powered hydraulically and/or pneumatically. 
     As depicted in  FIG. 5 , the vehicle  1  also includes a control means in the form of a control unit  8  operatively connected to the actuator  50  and to the input panel  45  for receiving commands therefrom. Deployment of the platform  3  is determined by virtue of the position of the actuator  50 , but it is envisaged that the vehicle  1  may include a sensor for sensing independently the position of the platform  3 . The actuator mechanism  5  also includes a load sensing means (not shown) incorporating a sensor (not shown) for sensing a load on the platform  3 . In this embodiment the control unit  8  also receives signals from other vehicle control features or modules or units (not shown) to determine the state of various aspects of the vehicle  1 , including for example the rear door position and the presence of obstructions adjacent the rear of the vehicle  1  detected by the rear parking sensors (not shown). 
     For purposes of this disclosure, and notwithstanding the above, it is to be understood that the controller(s), control units of control modules described herein may each comprise a control unit or computational device having one or more electronic processors. Vehicle  1  may comprise a single control unit or electronic controller or alternatively different functions of the vehicle control affected by the controller(s) may be embodied in, or hosted in, different control units or controllers or control modules. As used herein, the term “control unit” will be understood to include both a single control unit or controller and a plurality of control units or controllers collectively operating to provide the required control functionality. A set of instructions could be provided which, when executed, cause said controller(s) or control unit(s) or control module(s) to implement the control techniques described herein (including the method(s) described below). The set of instructions may be embedded in one or more electronic processors, or alternatively, may be provided as software to be executed by one or more electronic processor(s). For example, a first controller may be implemented in software run on one or more electronic processors, and one or more other controllers may also be implemented in software run on or more electronic processors, optionally the same one or more processors as the first controller. It will be appreciated, however, that other arrangements are also useful, and therefore, the present invention is not intended to be limited to any particular arrangement. In any event, the set of instructions described above may be embedded in a computer-readable storage medium (e.g., a non-transitory storage medium) that may comprise any mechanism for storing information in a form readable by a machine or electronic processors/computational device, including, without limitation: a magnetic storage medium (e.g., floppy diskette); optical storage medium (e.g., CD-ROM); magneto optical storage medium; read only memory (ROM); random access memory (RAM); erasable programmable memory (e.g., EPROM ad EEPROM); flash memory; or electrical or other types of medium for storing such information/instructions. 
     The control unit  8  is configured to ensure safe operation of the platform  3  between deployed and retracted positions. More specifically, the control unit  8  is configured to prevent movement of the door  12  and/or platform  3  under certain conditions or circumstances. For example, movement of the door  12  and platform  3  is prevented if an obstruction is detected in the area in which movement thereof might interfere with the obstruction. Similarly, movement of the platform  3  is prevented when in the deployed position and a load is detected. In addition, movement of the door  12  is prevented when the platform  3  is in the deployed position, and movement of the platform  3  is prevented when the door  12  is in a closed or partially closed position, to prevent damage. 
     In use and when the door  12  is in a closed condition, the platform  3  is in the retracted position of  FIGS. 1 and 3 , and is located within the storage compartment  10  of the vehicle  1 , the door  12  is secured by a locking feature (not shown) thereof, which cooperates with the lock feature  44  of the vehicle  1 . In this embodiment, the vehicle  1  enables either manual or automatic opening of the door  12 . The door  12  is opened by disengaging the locking feature  44  either automatically using one or more actuators operated by the vehicle&#39;s onboard control system or manually by operation of a handle (not shown). The door  12  is then raised as shown by arrow A in  FIG. 5 , thereby exposing the rear opening  11 . 
     With the door  12  in an open position, a user (not shown) is able to access the storage compartment  10  of the vehicle  1  through the partially obstructed opening  11  by reaching over the upright platform  3 . As with a split tailgate, this can be useful where items located on the load floor of the vehicle adjacent the rear door are loose or have moved during transport and there is a risk that they might otherwise fall out of the vehicle if the door was opened entirely. 
     If unfettered access to the storage compartment  10  is required, the user (not shown) depresses one of the buttons on the input panel  45  which sends an electrical signal indicative of the users operation of the button to the control unit  8 , which upon receipt thereof activates the actuator  50 . The actuator  50  retracts the piston  53  into the cylinder  52  as depicted by arrow B, which pulls the lever arm  51  causing it to rotate as indicated by arrow C about the hinge  7 , thereby moving the platform  3  from the upright position to the deployed position as indicated by arrow D. This extends fully the tether  6  such that any load placed on the platform  3  tensions the tether  6 , thereby supporting the load and preventing or at least inhibiting any further movement of the platform  3 . In the deployed position, the platform  3  aids loading of large items by acting as an extended load floor and can also be used as a convenient surface, for example as a social seat, a work surface or a table. 
     In this embodiment, a user is also able to configure the control unit  8  to deploy automatically the platform  3  on opening of the door  12 . This is done via the onboard HMI (not shown) of the vehicle in this embodiment. The control unit  8  may be configured for such automatic deployment upon automatic and/or manual opening of the door  12 . The circumstances under which the initiation of automatic deployment of the platform is allowed can also be configured. For example, the control unit  8  may be configured to initiate deployment of the platform  3  when the door  12  reaches a predetermined angle of opening and/or after a predetermined time period has elapsed. Further possible circumstances and characteristics relevant to safety and convenience are also envisaged within the scope of the invention and would be appreciated by those skilled in the art. 
     In addition, a user is also able to manually override the actuator  50  by depressing one of the buttons on the input panel  45 . This disables the electromechanical linear actuator  50 , thereby allowing the user to manipulate manually the platform  3  between the upright and deployed positions against the light spring biasing force of the retraction mechanism  32 . In the event of an electrical fault with the control unit  8  or vehicle  1 , the actuator  50  is also disabled automatically, which enables such manual operation. 
     It will be appreciated that various changes and modifications can be made to the present invention without departing from the scope of the present application. 
     An adaptable vehicle load floor  1  in accordance with an embodiment of the present invention is described herein with reference to  FIGS. 7 to 22  and  FIG. 6 . 
     As illustrated in  FIGS. 7 to 22  and  FIG. 6 , an adaptable load floor assembly  61  is incorporated in a storage compartment  70  of a vehicle  1 . The load floor assembly  61  includes a base  62  and a deployable section  63  that is reconfigurable between five different configurations including a stowed condition as shown in  FIG. 7 , a barrier configuration as shown in  FIGS. 9 and 10 , an extended load floor configuration as shown in  FIGS. 12 and 13 , a shelf configuration as shown in  FIGS. 15 and 16  and a partition configuration as shown in  FIGS. 18 and 19 . The vehicle  1  includes a door  12  hinged along a horizontal axis to the top of the rear opening that engages with a lock feature  71   a  at the center of a lip  71   b  adjacent the end of the load floor assembly  61 . 
     As shown more clearly in  FIGS. 10 and 19 , the base  62  includes a load surface  80 , a base frame  81 , a pair of upright side frames  82  and a substitute floor  83 . The base frame  81  includes a pair of side rails  85 . The load surface  80  is secured to and supported by the base frame  81  and extends between and lies contiguous with the side rails  85 . Each side frame  82  includes a square-shaped recess with four locking holes  87   a ,  87   b ,  87   c ,  87   d  one at each of its corners. The upper corners of the recess of the side frame  82  are chamfered and each chamfered corner includes a semi-circular notch  88   a ,  88   b  concentric with a respective one of the upper locking holes  87   a ,  87   b . The base frame  81  also includes a pair of semi-circular notches  88   c ,  88   d  concentric with a respective one of the lower locking holes  87   c ,  87   d.    
     The deployable section  63  includes a main body panel  90 , a pair of side members  91 , between which the main body panel  90  is mounted, and a secondary panel  92  pivotally attached to the upper edge of the main body panel  90 . Each side member  91  includes a tether  93 , first and second pivot pins  94 ,  95  both on an outer side adjacent the upper end thereof and a body panel locking pin hole  96  on an inner side adjacent the upper end thereof. The tether  93  is retractably mounted to an upper portion of a respective side member  91 . Each pivot pin  94 ,  95  is retractable into the side member  91  and operable by a respective actuator mechanism  94   a ,  95   a  on the main body panel  90 . As illustrated in  FIG. 20 , each of the pivot pin actuators mechanism  94   a ,  95   a  is releasably connected to a respective one of the pivot pin pairs  94 ,  95  by cooperating key features  97   a ,  97   b  in the actuator mechanism  94   a ,  95   a  and pins  94 ,  95  and each pivot pin pair  94 ,  95  is resiliently biased toward the deployed position by a compression spring  98 . 
     The main body panel  90  is pivotally mounted between the side members  91  by a pair of lower pins (not shown) received within bearings (not shown) mounted to the lower end of the side members  91  with one end of each tether  93  secured to a respective upper end of the body panel  90 . The upper end of the main body panel  90  also includes a pair of retractable locking pins  96   a  for cooperating with the locking pin holes  96  of the side members  91 , thereby to secure the main body panel  90  to the side members  91  such that it extends between and contiguous with the side members  91 . The main body panel  90  includes the first pivot pin actuator mechanism  94   a , the second pivot pin actuator  95   a  and a locking pin actuator  96   b . Operation of the body panel locking pin actuator  96   b , which involves sliding it toward the right in this embodiment, both retracts the locking pins  96   a  and simultaneously disengages the actuator mechanisms  94   a ,  95   a  and pins  94 ,  95 , as illustrated by the arrow A in  FIG. 20 . 
     As illustrated in  FIGS. 21 and 22 , each pivot pin  94 ,  95  includes a stepped end providing a engagement portion  94   b ,  95   b . As illustrated in  FIG. 21 , each of the upper locking holes  87   a ,  87   b  is sized to receive the engagement portion  94   b ,  95   b  of one of the pivot pins  94 ,  95 . As illustrated in  FIG. 22 , each of the lower locking holes  87   c ,  87   d  includes a bearing 89 sized to receive the engagement portion  94   b ,  95   b  of one of the pivot pins  94 ,  95  to facilitate rotation of the pins  94 ,  95 . 
     When the load floor assembly  61  is in the stowed condition, as shown in  FIG. 7 , the first pair of pivot pins  94  engage a first pair of the lower locking holes  87   c  and the second pair of pivot pins  95  engage the second pair of lower locking holes  87   d.    
     In use and starting with the load floor assembly  61  in the stowed condition, a user grips and actuates the first pivot pin actuator mechanism  94   a , which is done by clockwise rotation in this embodiment. Actuation of the first pivot pin actuator mechanism  94   a  causes the first pair of pivot pins  94  to retract from the first pair of lower locking holes  87   c  and into the main body panel  90  thus freeing the innermost edge of the deployable section  63 . As illustrated by  FIG. 8 , the user then pulls the first pivot pin actuator mechanism  94   a  to lift the deployable section  63  into an upstanding orientation and rotates the actuator mechanism  94   a  back to its original orientation to release the first pivot pins  94 , which then engage a first pair of the upper locking holes  87   a  to secure the deployable section  63  in the barrier configuration. In this position, the substitute floor is slightly lower than the load surface  80 , thereby providing a depression in the load floor assembly  61 . It is also envisaged that the first pivot pin actuator mechanism  94   a  could be spring loaded such that it returns automatically to the original orientation upon release. 
     The user may then reconfigure the load floor assembly  61  into the open configuration shown in  FIGS. 12 and 13  by sliding the main body panel locking pin actuator  96   b  to the right and pulling it downwardly. As explained above, operation of the body panel locking pin actuator  96   b  retracts the locking pins  96   a  and disengages the actuator mechanisms  94   a ,  95   a  from the pins  94 ,  95 , thereby allowing the main body panel  90  to pivot as shown in  FIG. 11  from the barrier configuration to the extended load floor configuration, where it extends out of the rear opening of the vehicle  1  to aid loading of large items by acting as an extended load floor and/or to provide a support surface, e.g. a seat. As shown in  FIG. 13 , pivoting the main body panel  90  relative to the side members  91  also causes the substitute floor  83  to be raised into a position that substantially bridges the gap between the load surface  80  and the body panel  90 , while the tethers  93  support the main body panel  90  in this position. 
     Alternatively, the user can reconfigure the load floor assembly  61  from the barrier configuration of  FIGS. 9 and 10  to the shelf configuration shown in  FIGS. 15 and 16 . In this embodiment, the secondary panel  92  is held in place by a magnet latch (not shown), so the lower end of the secondary panel  92  must be pulled firmly to overcome the magnetic latch and the secondary panel  92  is then rotated relative to the main body panel  90  as shown in  FIG. 14  to a horizontal orientation thereby to provide a horizontal support surface  92   a . It is envisaged that the support surface  92   a  may be used to support one or more items, such as drinks or food and/or it may be used as a workspace or desk space in use. 
     In situations where a user wishes to separate the storage compartment, for example where a smaller load that is susceptible to movement during travel, the load floor assembly  61  may be reconfigured into the partition configuration shown in  FIGS. 18 and 19 . This is achieved starting with the load floor assembly  61  in the stowed condition of  FIG. 7 . The user grips and actuates by clockwise rotation the second pivot pin actuator  95   a , which causes the second pair of pivot pins  95  to retract from the second pair of lower locking holes  87   d  and into the side members  91 , thereby freeing the outermost edge of the deployable section  63 . As illustrated by  FIG. 17 , the user then pulls the second pivot pin actuator  95   a  to lift the deployable section  63  into an upright orientation and rotates the actuator  95   a  back to its original orientation to release the second pivot pins  95 , which then engage the second pair of the upper locking holes  87   b  to secure the deployable section  63  in the partition configuration. It is also envisaged that the second pivot pin actuator  95   a  could be spring loaded such that it returns automatically to the original orientation upon release. 
     As illustrated in  FIG. 19 , the substitute floor  83  remains in its lowered position such that the rear of the vehicle provides a small edge to inhibit a load received on the substitute floor  83  from falling out of the vehicle  1  when the rear door  12  is opened after a journey. 
     While operation of the load floor assembly is manual in this embodiment, it is envisioned that such operation may be automated and/or controlled by a control module  73  of the vehicle either in addition to or as an alternative to the manual actuation described above. In fact, it is considered by the applicants that it would be advantageous in some circumstances to provide one or a series of actuators that are operable automatically to selectively retract one or more of the pins  94 ,  95 ,  96   a  and/or to selectively disengage one or each of the actuator mechanisms  94   a ,  95   a  from the pins  94 ,  95 . It will also be advantageous in some circumstances to provide one or a series of motors that are operable automatically to move the deployable section  63  between the various positions described above. In such circumstances, embodiments of the invention may include a control means or module or system and/or an associated program element or algorithm for executing such automatic operation. This operation may be controlled by a user and/or in some circumstances the automatic operation may be partially or entirely autonomous based on predetermined conditions.
