[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] Vehicles such as pickup trucks may have a drop-down tailgate that provides access to a rear cargo bed. A typical tailgate is attached to the rear of the vehicle body so that the tailgate is movable relative to the vehicle body between a closed position and an open position. In the closed position, the tailgate blocks the rear tailgate opening and is generally perpendicular to the floor of the cargo bed. In the open position, the tailgate is generally parallel to the floor of the cargo bed. However, the floor of the cargo bed and the tailgate in the open position are typically relatively high off the ground to provide sufficient ground clearance for the vehicle. For some people, climbing onto or exiting the cargo bed may be difficult due to the height of the open tailgate. Additionally, it may be beneficial to reduce the weight of the vehicle to increase power efficiency (e.g., to increase fuel efficiency or battery range).

[0034] refer to Figure 1 and Figure 2 , shows the rear portion of a vehicle 10. In the example provided, the vehicle 10 is a pickup truck, but other configurations may be used. The vehicle 10 includes a body 14, a rear bumper 18, and a tailgate 22. The body 14 includes a left bed wall 26, a right bed wall 30, a front bed wall 34, and a bed floor 38 that cooperate to define a cargo bed 42. In the example provided, the top of the cargo bed 42 is open, but other configurations may be used, for example, using a rear seat cover or a truck bed lid.

[0035] The tailgate 22 includes a tailgate panel 46, a left tailgate latch 50, a right tailgate latch 54, and a step assembly 58. The tailgate panel 46 is a generally "U" shaped body. The "U" shape of the tailgate panel 46 is defined by a bottom portion 62, a left side portion 66, and a right side portion 70. The bottom portion 62 spans between the left and right compartment walls 26, 30. When the tailgate panel 46 is in the closed position ( Figure 1 ), the left side portion 66 extends upwardly from the left side of the bottom portion 62. When the tailgate panel 46 is in the closed position ( Figure 1 ), the right side portion 70 extends upwardly from the right side of the bottom portion 62. The left side portion 66 and the right side portion 70 are spaced apart from each other in the lateral direction of the vehicle 10 to define a cutout or step cavity 74 ( Figure 3).

[0036] The bottom portion 62, the left side portion 66, and the right side portion 70 are generally coplanar, but not necessarily flat or smooth, such that the bottom portion 62, the left side portion 66, and the right side portion 70 generally form a cargo side 78 of the tailgate panel 46 (facing forward into the cargo bed 42 when the tailgate panel 46 is in the closed position). Figure 1 ) and rearwardly toward the side 82 (rearwardly away from the cargo bed 42 when the tailgate panel 46 is in the closed position, Figure 1 Likewise, the bottom portion 62 and the left side portion 66 generally form a left side 86 of the tailgate panel 46 that faces the left compartment wall 26, while the bottom portion 62 and the right side portion 70 generally form a right side 90 of the tailgate panel 46 that faces the right compartment wall 30. The left side portion 66 and the right side portion 70 form a top side 94 of the tailgate panel 46 that is generally aligned with the tops of the left and right compartment walls 26, 30 when the tailgate panel 46 is in the closed position ( Figure 1 ).

The linkage 314 is configured to allow the step panel 310 to be positioned relative to the tailgate panel 46 in the stowed position ( Figure 1 and Figure 2 ) and the expanded position ( Figure 3 ). The step panel 310 has a shape complementary to the step cavity 74 such that the step panel 310 is matingly received in the step cavity 74. In the example provided, the step cavity 74 and the step panel 310 have complementary square or rectangular shapes, but other shapes may be used.

[0041] The step panel 310 has a top side 326, a bottom side 330, a left side 334, a right side 338, a cargo side 342, and a rearward side 346. Figure 2 ), top side 326 is generally aligned with top side 94 of transom panel 46, bottom side 330 is opposite the top of bottom portion 62, left side 334 is opposite the right side of left portion 66, and right side 338 is opposite the left side of right portion 70. Figure 2 ), the cargo side 342 is generally aligned with the cargo side 78 of the tailgate panel 46 , and the rearward side 346 is generally aligned with the rearward side 82 of the tailgate panel 46 .

[0042] The left step latch 318 is configured to releasably connect the left side 334 to the left side portion 66, and the right step latch 322 is configured to releasably connect the right side 338 to the right side portion 70. In the example provided, the right step latch 322 is mounted to the top of the right side 338 and is configured to engage a latch target 350 fixedly mounted to the right side portion 70. In the example provided, the left step latch 318 is mounted to the top of the left side 334 and is configured to engage a latch target (not shown, but can be similar to the latch target 350) fixedly mounted to the left side portion 66. The left step latch 318 and the right step latch 322 can be mechanically or electrically released by actuating a lever or button 354.

[0043] The linkage 314 couples the step panel 310 to the left and right portions 66, 70 and is configured to allow the step panel 310 to be positioned relative to the tailgate panel 46 in the stowed position ( Figure 2 ) and the expanded position ( Figure 3 ). In the example provided, the linkage 314 is a four-bar linkage type mechanism including a left first link 358, a right first link 362, a left second link 366, and a right second link 370, wherein the tailgate panel 46 constitutes the third link of the four-bar linkage and the step panel 310 constitutes the fourth link of the four-bar linkage. The linkage 314 may also include a position lock 374.

[0044] The left first link 358 is a rigid member having a proximal end pivotally coupled to the right side of the left portion 66 and a distal end pivotally coupled to the left side 334 of the step panel 310. The left second link 366 is a rigid member having a proximal end pivotally coupled to the right side of the left portion 66 at a different position than the left first link 358. The left second link 366 has a distal end pivotally coupled to the left side 334 of the step panel 310 at a different position than the left first link 358.

[0045] The right first link 362 is similar to the left first link 358, but has a proximal end pivotally coupled to the left side of the right side portion 70 and a distal end pivotally coupled to the right side 338 of the step panel 310. The right second link 370 is similar to the left second link 366, but has a proximal end pivotally coupled to the left side of the right side portion 70 and a distal end pivotally coupled to the right side 338 of the step panel 310. In the example provided, the proximal and distal ends of the links 358, 362, 366, 370 pivot about axes that are parallel to each other and extend in the lateral direction of the vehicle 10. In the example provided, the proximal ends of the first links 358, 362 are closer to the bottom portion 62 than the proximal ends of the second links 366, 370, and the proximal ends of the links 358, 362, 366, 370 are closer to the top side of the tailgate panel 46 than to the bottom portion 62. In the example provided, the distal ends of the first links 358, 362 are closer to the bottom side 330 of the step panel 310 than the distal ends of the second links 366, 370, and the distal ends of the links 358, 362, 366, 370 are closer to the bottom side 330 of the step panel 310 than to the top side 326. In the example provided, the links 358, 362, 366, 370 have the same length. In the example provided, the links 358, 362, 366, 370 are perpendicular to the ground and generally perpendicular to the tailgate panel 46 and the step panel 310 when in the deployed position.

[0046] The linkage 314 is configured to be in the stowed position ( Figure 2 ), Expand Position( Figure 3 ) and when moving between the stowed position and the deployed position, the step panel 310 is maintained in an orientation parallel to the tailgate panel 46. Figure 3 ), the cargo side 342 of the step panel 310 is below the tailgate panel 46. In this position, the top side 326 of the step panel 310 is also rearward of the top side of the tailgate panel 46. The linkage 314 is constructed of a material strong enough to carry a person carrying cargo when in the deployed position.

[0047] The position lock 374 is configured to lock the linkage in the deployed position ( Figure 3). A position lock 374 can be located on the tailgate panel 46 as shown in phantom and can engage one or more of the links 358, 362, 366, 370 and can prevent the links 358, 362, 366, 370 from moving when engaged. In an alternative construction not shown, the position lock 374 can be located on the step panel 310 to engage one or more of the links 358, 362, 366, 370. The position lock 374 can be configured to automatically engage when the step panel 310 reaches the deployed position and can be disengaged by a button or lever. In one construction, the same button or lever (e.g., button 354) used to disengage the step latches 318, 322 can be used to disengage the position lock 374. In another construction, a different button or lever (not shown) can be used.

[0048] The biasing member 324 may be a member configured to bias the step member toward the stowed position ( Figure 1 and Figure 2 ) or expanded position ( Figure 3 ) is any suitable type of resilient member that is biased. In the example provided, the biasing member 324 is a spring that is attached at one end to the tailgate panel 46 and at the other end to the step panel 310 and is configured to bias the step panel 310 toward the stowed position. In an alternative configuration not specifically shown, one or more torsion springs may be disposed within the tailgate panel 46 and / or the step panel 310 and configured to rotationally bias the links 358, 362, 366, 370 toward the stowed position or the deployed position.

[0049] Additional references Figure 4 , showing a second configuration of the vehicle 10 ′. Except as otherwise shown or described herein, the vehicle 10 ′ is similar to the vehicle 10 ( Figure 1-3 ). and the characteristics of the vehicle 10 ( Figure 1-3 ) Similar features of the vehicle 10' are indicated by similar, but primed, reference numerals, and only the differences are described in detail herein. In the example provided, the tailgate panel 46' includes a cover member 410. The cover member 410 is generally flat and flush with the cargo side 78' of the tailgate panel 46'. The cover member 410 spans laterally between the left and right portions 66', 70' and extends from the bottom portion 62' of the tailgate panel 46' toward the top side 94' a distance less than the full distance to the top side 94'.

[0050] The cargo side 342' of the step panel 310' may include a recess (not shown) corresponding to the cover member 410 so that when the step panel 310' is in the stowed position (similar to Figure 1 and Figure 2), the cover member 410 is nested in the recess (not shown) and the non-recessed area of ​​the cargo side 342' of the cover member 410' is generally aligned with the cargo side 412 of the cover member 410 and the cargo side 78' of the tailgate panel 46'. In the example provided, when the step panel 310' is in the deployed position, the top end 414 of the cover member 410 is rearward of the bottom side 330' of the step panel 310' ( Figure 4 ).

[0051] Additional references Figure 5 , showing a third configuration of vehicle 10 ″. Vehicle 10 ″ is similar to vehicle 10 ( Figure 1-3 ). and the characteristics of the vehicle 10 ( Figure 1-3 ) Features similar to vehicle 10" are indicated by similar but double-prime reference numerals, and only the differences are described in detail herein. In the example provided, the linkage 314" is a scissor mechanism rather than a four-bar linkage. The linkage 314" includes a set of left scissor links 510 and a set of right scissor links 514. The set of left scissor links 510 connects the left side portion 66" to the left side 334" of the step panel 310". The set of right scissor links 514 connects the right side portion 70" to the right side 338" of the step panel 310".

[0052] One end of one of the two right scissor links 514 directly connected to the right side portion 70" is connected to the right side portion 70" in such a manner that it pivots relative to the right side portion 70", but is otherwise fixed relative to the right side portion 70". One end of the other of the two right scissor links 514 directly connected to the right side portion 70" is connected to the right side portion 70" in such a manner that it pivots relative to the right side portion 70" and also translates along a track 518 formed in the right side portion 70". Although Figure 5 Not specifically shown in the drawings, but two left scissor links 510 directly connected to the left side portion 66" are connected to the left side portion 66" in a similar manner so that one pivots while the other pivots and translates.

[0053] Similarly, one end of one of the two left scissor links 510 directly connected to the left side 334" of the step panel 310" is connected to the left side 334" in such a manner that it pivots relative to the left side 334" but is otherwise fixed relative to the left side 334". One end of the other of the two left scissor links 510 directly connected to the left side 334" is connected to the left side 334" in such a manner that it pivots relative to the left side 334" and also translates along the track 522 formed in the left side 334". Although Figure 5Not specifically shown, the two right scissor links 514 connected directly to the right side 338" are similarly connected to the right side 338", so that when one pivots, the other pivots and translates. Thus, the linkage 314" is configured to maintain the step panel 310 generally parallel to the tailgate panel 46" as it moves from the stowed position to the deployed position.

[0054] In the example provided, the biasing member 324" is a spring having one end attached to the tailgate panel 46" and the other end attached to the step panel 310". In the example provided, the biasing member 324" is configured to bias the step panel 310" toward the deployed position, but other configurations may be used.
