VEHICLE BODY STRUCTURE
A door structure is moveable to and from of a closed orientation covering a door opening and an open orientation exposing the door opening of a vehicle. The door structure has an inner door panel with an interior latch handle attachment area and an attenuation slot adjacent to the interior latch handle attachment area. The attenuation slot is defined between a first slot edge and a second slot edge. The interior latch handle is installed to the interior latch handle attachment area. A portion of the interior latch handle is located adjacent to the first slot edge of the attenuation slot. In response to an impact event proximate a central area of the door structure, the door structure and the interior latch handle attachment area deform such that the first slot edge and the interior latch handle move relative to the second slot edge of the attenuation slot.

The present disclosure generally relates to a vehicle body structure. More specifically, the present disclosure relates to a vehicle body structure with an inner door panel that includes an attenuation slot adjacent to an interior door handle such that in response to an impact event where impact forces deform a central area of the door, the attenuation slot attenuates movement of the interior door handle resulting from impact related deformation of the inner door panel.
Background InformationVehicle body structures, such as doors are provided with interior door handles that area mechanically connected to door latch mechanisms. In a closed position, one end of a door having an interior door handle and a door latch mechanism is fixed to the vehicle body structure by heavy duty hinges. An opposite end of the door is releasably latched to an adjacent pillar of the vehicle body structure by the door latch mechanism. In response to an impact event where the door of the vehicle is impacted by an impacting force, it is advantageous to keep the door of the vehicle in a closed orientation so that the adjacent pillars that support the door can absorb a portion of the impacting forces.
SUMMARYOne object of the present disclosure is to prevent a vehicle door from opening during an impact event.
In view of the state of the known technology, one aspect of the present disclosure is to provide a vehicle body structure with a door structure and an interior latch handle. The door structure is configured to attach to a vehicle and move to and from each of a closed orientation covering a door opening of the vehicle and an open orientation exposing the door opening when attached to the vehicle. The door structure has an inner door panel defining an interior latch handle attachment area and an attenuation slot adjacent to the interior latch handle attachment area. The attenuation slot is defined between a first slot edge and a second slot edge. The interior latch handle is installed to the interior latch handle attachment area of the inner door panel. A portion of the interior latch handle is located adjacent to the first slot edge of the attenuation slot such that with the door structure in a non-deformed state the interior latch handle is in a generally upright orientation and the first slot edge is adjacent to the second slot edge. In response to an impact event proximate a central area of the door structure, the door structure and the interior latch handle attachment area deform such that the first slot edge and the interior latch handle move relative to the second slot edge of the attenuation slot.
Referring now to the attached drawings which form a part of this original disclosure:
Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
Referring initially to
The vehicle body structure 12 also includes, among other features, an A-pillar 20a, a B-pillar 20b, a passenger compartment 22 and a door opening 24 defined between the A-pillar 20a and the B-pillar 20b. The door opening 24 provides access to the passenger compartment 22. The door 14 (also referred to as the door structure 14) is attached to the A-pillar 20a of the body vehicle structure 12 such that it is movable to and from each of a closed orientation (
The vehicle body structure 12 defines a vehicle longitudinal direction DL, as shown in
The door structure 14 includes an outer door panel 30 (
The inner door panel 32 has a forward section 32a, a main panel portion 32b and a rearward section 32c. The forward section 32a extends vertically along a forward end of the main panel portion 32a. The rearward section 32c extends along a rearward end of the main panel portion 32b with the hollow interior 34 of the door structure 14 being at least partially defined along the main panel portion 32b between the forward section 32a and the rearward section 32c. The main panel portion 32b of the inner door panel 32 includes an inboard area 36 (an interior latch handle attachment area 36). The inboard area 36 is located near an upper edge 32d of the inner door panel 32. The inboard area 36 further includes an attachment hole Hi that is configured to receive a mechanical fastener F1. As described further below, the interior latch handle 18 is installed to the inboard area 36 (the interior latch handle attachment area 36) via the mechanical fastener F1. Hence, inboard area 36 can also be referred to as the interior latch handle attachment area 36.
The inner door panel 32 is provided with an attenuation slot 38 that extends from an area rearward and adjacent to the inboard area 36 along a lower portion of the inboard area 36. In the first embodiment, the attenuation slot 38 has an overall L-shape as viewed from an inboard side 32f of the inner door panel 32. The lower portion of the attenuation slot 38 (the horizontal portion of the L-shape) extends from rearward of the inboard area 36 along a lower section of the inboard area extending about a third of the overall length of the inboard area 36.
The attenuation slot 38 is defined between a first slot edge 38a and a second slot edge 38b. The first slot edge 38a defines a forward and upper boundary of the attenuation slot 38. The second slot edge 38b defines a rearward and lower boundary of the attenuation slot 38.
The attenuation slot 38 is basically an extended or elongated opening in the inner door panel 32 that extends from an outboard side 32e to an inboard side 32f of the inner door panel 32. As is described in greater detail below, in response to an impact event where an impacting force is applied proximate a central area of the outer panel 30 of the door structure 14, the door structure 14 and the interior area 36 can deform at a rate that differs from deformation of the second slot edge 38b of the attenuation slot 38. Or, put another way, the first slot edge 38a can undergo limited inboard movement while the second slot edge 38b has more freedom to undergo deformation inboard (movement in the inboard direction).
A window regulator mechanism 40 is installed to the inner door panel 32 in a conventional manner such that a window W is movable from a lowered position (not shown) within the hollow interior 34 and a raised position (
The door structure 14 further defines a window receiving slot S (
A description of the door latch mechanism 16 (also referred to as the latch mechanism 16) is provided now with specific reference to
The internal operating mechanism (not shown) of the latch mechanism 16 includes conventional mechanical components that are well known in the art. Therefore, further description of the latch mechanism 16 is omitted for the sake of brevity.
As shown in
As shown in
The release lever 58 is operably connected to the latch mechanism 16 via the cables C1 and C2 such that when the release lever 58 is moved to the door opening orientation, the latch mechanism 16 releases the door structure 14 such that the door structure 14 can move to the open orientation. The release lever 58 is biased to return to the at rest orientation by a spring (not shown) such that if the door is moved to the closed orientation, the latch mechanism 16 can retain and lock the door structure 14 in the closed orientation.
In certain circumstances, the impact event can cause the release lever 58 to move from the at rest orientation (door close orientation) shown in
The inclusion of the attenuation slot 38 provides a break line in the propagation of deformation of the inner door panel 32. Specifically, in the absence of other forces acting thereon, an area 32h (circled with a phantom line in

During an impact event, such at that demonstrated in
It should be understood from the above description that the lower rearward corner ELR of the housing 56, the first slot edge 38a and the lower rear edge 38b of the slot 38 of the inner door panel 32 have all moved in the inboard direction DI. However, due to the presence of the interior object F2 and the reactionary forces associated with the location of the interior object F2, the lower rear edge 38b of the slot 38 of the inner door panel 32 has moved a greater distance in the inboard direction DI, than the lower rearward corner ELR of the housing 56 and the first slot edge 38a. Hence, as in the above descriptions, the lower rearward corner ELR of the housing 56 and the first slot edge 38a appear to move in the outboard direction Do relative to the lower rear edge 38b of the slot 38 of the inner door panel 32.
Put another way, deformation related movement of the lower rearward corner ELR of the housing 56 and the first slot edge 38a are limited by contact with the interior object F2 relative to deformation related movement of the lower rear edge 38b of the slot 38 of the inner door panel 32.
Second EmbodimentReferring now to
In the second embodiment, the inner door panel 32 of the first embodiment is replaced with the inner door panel 132. The inner door panel 132 is identical to the inner door panel 32 of the first embodiment, except that the slot 38 of the first embodiment is replaced with the attenuation slot 138 of the second embodiment.
The attenuation slot 138 is formed in the inner door panel 132 in generally the same location as the attenuation slot 38 of the first embodiment. Specifically, the attenuation slot 138 is located at a lower rearward corner of the inboard area 36.
The attenuation slot 138 has an oval or elliptical shape that is rotated slightly such that a rear end thereof is higher than a front end thereof. The attenuation slot 138 defines a deformation brake line with the same properties as the attenuation slot 38 of the first embodiment.
Third EmbodimentReferring now to
In the third embodiment, the inner door panel 32 of the first embodiment is replaced with the inner door panel 232 of the third embodiment. The inner door panel 232 is identical to the inner door panel 32 of the first embodiment, except that the slot 38 of the first embodiment is replaced with the attenuation slot 238 of the third embodiment.
The attenuation slot 238 is formed in the inner door panel 232 in generally the same location as the attenuation slot 38 of the first embodiment. Specifically, the attenuation slot 238 is located at a lower rearward corner of the inboard area 36 of the inner door panel 32.
The attenuation slot 238 has a rectangular shape with curved corners. The attenuation slot 238 defines a deformation brake line with the same properties as the attenuation slot 38 of the first embodiment.
