Description

  The present invention relates to a vehicle door structure that can protect a passenger accurately by applying a door pocket in the event of a side collision of the vehicle.

  When a collision from the side occurs with respect to the vehicle, an external force is applied from the outside of the door, the door panel is deformed, the door trim is displaced toward the passenger compartment, and the door trim contacts the occupant and a load is applied. . When the door trim comes into contact with the occupant, it is important that the occupant receive a minimum load without applying an excessive load.

  If the door trim abuts against the occupant violently, the abdomen and chest may cause injury, so the occupant is restrained by abutting around the waist, which is relatively resistant, i.e., the occupant is deformed according to the deformation of the door trim. It is desirable to move it. For this reason, a technique for protecting the occupant by restraining the lumbar part by projecting a door trim (door pocket) next to the occupant's lumbar region, particularly in the vicinity of the iliac center behind the acetabulum in the pelvic skeleton has been proposed ( For example, see Patent Document 1).

  In order to protect the occupant's waist accurately, the burden on the pelvis needs to reduce the impact of both the acetabulum and the iliac, and it is preferable that the impact of the door trim is input to the iliac. I can't say that. Therefore, particularly for an occupant with low pelvic resistance, the load on the pelvis cannot be sufficiently reduced, and the occupant's waist may not be protected properly.

  For this reason, in order to protect the occupant's waist accurately, a structure such as providing an impact absorbing member that absorbs the impact instead of the door pocket is adopted, and there is a case where compatibility with occupant protection is insufficient. there were. Further, even when the door trim is brought into contact with the periphery of the waist portion having relatively high resistance, a structure for restraining the occupant by bringing the door trim into contact with a highly resistant portion is desired.

  On the other hand, as a door pocket of a vehicle, one that pulls out a pocket portion toward the passenger compartment side and stores small items, books, and the like has been conventionally known.

JP 2007-30563 A

  The present invention has been made in view of the above situation, and can apply a door pocket that is pulled out and used to the passenger compartment side to restrain the occupant in a state where the load on the occupant is accurately reduced with respect to input from the outside. An object is to provide a door structure of a vehicle.

  In order to achieve the above object, a vehicle door structure according to a first aspect of the present invention is a vehicle door structure including a drawer-type door pocket mechanism in a door trim, and the door pocket mechanism is formed on a door inner panel. A long length that is pierced through the opened opening so as to be reciprocally movable in the vehicle width direction, the distal end side is disposed on the vehicle interior side of the door inner panel, and the proximal end side is disposed on the vehicle outer side of the door inner panel and in the vicinity of the door outer panel. A movable member attached to the tip of the movable member, and reciprocally movable in the vehicle width direction together with the movable member, and can be pulled out from the door trim to the vehicle compartment side, and the door inner panel A regulating member that is disposed at a first position having a predetermined distance from the door inner panel on the outside of the vehicle, and that regulates a moving range of the moving member toward the vehicle side in the vehicle width direction; The restricting member is displaced from the first position to a second position where the inner member touches the inner panel when an input greater than or equal to a predetermined value is applied from the outside of the vehicle toward the passenger compartment. The restriction on the movement range to the passenger compartment is canceled.

  In the present invention according to claim 1, the pocket portion can be reciprocated to the vehicle compartment side via the moving member, and the pocket portion can be pulled out for use. When there is a predetermined input or more from the outside to the inside of the passenger compartment at the time of a side collision or the like, the restricting member that restricts the movement range of the pocket portion (moving member) to the passenger compartment side from the first position. The restriction is released by being displaced to the second position on the passenger compartment side, and the pocket portion can be moved to a state where the pocket portion is protruded more toward the passenger compartment side than during normal drawer. That is, it is possible to increase the phase difference between the door trim and the pocket portion more reliably at the time of a side collision. Therefore, the passenger can be surely pushed and restrained toward the passenger compartment at the pocket portion, and the impact of the portion other than the pocket portion can be reduced.

  For this reason, the door pocket mechanism used by being pulled out to the passenger compartment side is applied, and the occupant can be restrained in a state where the load on the occupant is more accurately reduced with respect to the input from the outside.

  In the present invention according to claim 2, the opening of the door inner panel is normally only when the regulating member is held at the first position by the clip and a predetermined input or more is applied from the outside of the vehicle toward the passenger compartment. The fitting of the part and the clip is released, and the displacement of the restricting member is allowed. Thereby, with a simple configuration, the phase difference between the pocket portion and the door trim at the time of a side collision can be reliably increased as compared with the normal time.

  A vehicle door structure according to a third aspect of the present invention is the vehicle door structure according to the first or second aspect, wherein the base end of the moving member faces an inner surface of the door outer panel. And a reaction force portion that is moved to the vehicle compartment side when an input acts from the vehicle exterior to the vehicle compartment side, and the restricting member is in contact with the reaction force portion. The moving range of the moving member toward the passenger compartment is restricted.

  In this invention which concerns on Claim 3, the movement range to the compartment side of a moving member is regulated by making a regulating member contact the reaction force part which is provided in the base end of the moving member and receives the input from the outside. Yes. As a result, the amount of pull-out of the pocket portion can be limited during normal withdrawal, and in the event of a side collision, the first restriction member can be reliably connected to the first by transmitting input from the outside of the vehicle to the restriction member via the reaction force portion. The second position can be displaced from the first position.

  A vehicle door structure according to a fourth aspect of the present invention is the vehicle door structure according to the first or second aspect, wherein the two members are disposed between the regulating member and the reaction force portion. And a biasing means for constantly biasing the reaction force portion toward the vehicle exterior.

  In the present invention according to claim 4, an urging means (for example, a compression spring) is provided between the regulating member held by the door inner panel and the reaction force portion, and the reaction force portion is always urged to the outside of the vehicle. Thus, the pocket portion is held in the stored state.

FIG. 6 shows a schematic plan view showing the state of the door pocket mechanism when there is an input from the outside (side surface) of the passenger compartment.

  A first embodiment of the door structure of the present invention will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, the rear door (door) 1 includes a door inner panel 2, a door outer panel 3, and a door trim 5 attached to the vehicle interior 4 side of the door inner panel 2. A door pocket mechanism 11 is provided inside the door 1. The door pocket mechanism 11 includes a box-shaped pocket portion 21 in which articles can be stored. The pocket portion 21 can be protruded and retracted, that is, the pocket portion 21 can be pulled out with respect to the door trim 5. A door pocket mechanism 11 is arranged corresponding to the position of the thigh 10 when the occupant 8 is seated on the rear seat (seat) 7.

  An opening 12 is formed in a portion of the door trim 5 corresponding to the door pocket mechanism 11, and a surface 21 a on the vehicle compartment 4 side of the pocket portion 21 of the door pocket mechanism 11 faces the opening 12. The door trim 5 and the surface 21a of the pocket portion 21 are flush with each other. The pocket portion 21 of the door pocket mechanism 11 can be pulled out toward the compartment 4 side.

  The configuration of the door pocket mechanism 11 will be described with reference to FIGS.

  As shown in FIGS. 3 and 4, the door pocket mechanism 11 includes a long connecting rod 22 (moving member) that can reciprocate in the vehicle width direction with respect to the door inner panel 2. The distal end side is disposed on the vehicle compartment 4 side (door trim 5 side) through the door inner panel 2, and the proximal end side is disposed on the vehicle outer side of the door inner panel 2 and in the vicinity of the inner side of the door outer panel 3. Specifically, an opening 2a is formed in the door inner panel 2, and the connecting rod 22 is provided so as to be capable of reciprocating in the vehicle width direction while penetrating through the opening 2a.

  And the pocket part 21 is attached to the front-end | tip of the connecting rod 22 located in the compartment 4 side (door trim 5 side) of the door inner panel 2. FIG. The pocket portion 21 is provided between the door trim 5 and the door inner panel 2 so that the surface 21 a on the vehicle compartment 4 side is flush with the surface of the door trim 5. And the pocket part 21 is arrange | positioned so as to oppose the thigh part 10 of the passenger | crew 8 seated on the rear seat (seat) 7 in the vehicle width direction.

  A reaction force plate 23 (reaction force portion) is attached to the base end of the connecting rod 22 so as to face the inner (vehicle compartment 4 side) surface of the door outer panel 3. The reaction force plate 23 is a disk-like member having a diameter larger than that of the connecting rod 22 and is movable in the vehicle width direction together with the connecting rod 22. The reaction force plate 23 is in a state of being in contact with the door outer panel 3 when the pocket portion 21 is housed in the door trim 5, and when the pocket portion 21 is pulled out, the connecting plate 22 and the vehicle interior 4 side (door inner side). Panel 2 side).

  Then, for example, when there is an input to the door outer panel 3 from the outside of the vehicle due to a side collision or the like, the reaction force plate 23 comes into contact with the deformed door outer panel 3 to receive the load and move to the vehicle compartment 4 side. It is configured. The reaction force plate 23 does not necessarily have to be in contact with the door outer panel 3 at a normal time, and may be set at a position where the input from the vehicle outer side can be reliably received in the vicinity of the door outer panel 3.

  A stopper plate 25 (regulating member) is attached to the vehicle outer side of the door inner panel 2 so as to face the opening 2a through which the connecting rod 22 passes. The stopper plate 25 is provided with a through-hole through which the connecting rod 22 passes, and the connecting rod 22 (reaction force plate 23) is movable in the vehicle width direction with respect to the stopper plate 25. On the door inner panel 2 side (vehicle compartment 4 side) of the stopper plate 25, a clip 26 is provided in a state of protruding toward the door inner panel 2 side (opening 2a).

  The tip of the clip 26 is fitted to the periphery of the opening 2a of the door inner panel 2, and the stopper plate 25 is placed at a position (first state) away from the door inner panel 2 by a predetermined distance. keeping. The stopper plate 25 is a member that abuts against the reaction force plate 23 at the base end of the connecting rod 22 and restricts the range of movement of the connecting rod 22 toward the vehicle compartment 4 side. In other words, the stopper plate 25 prevents movement of the reaction force plate 23 that is moved to the vehicle compartment 4 side according to the drawer of the pocket portion 21, thereby restricting the amount of the pocket portion 21 to be drawn to the vehicle compartment 4 side. .

  The stopper plate 25 is allowed to move (displace) to the door inner panel 2 side (vehicle compartment 4 side) when an input of a predetermined level or more is applied toward the vehicle compartment 4 side. Specifically, when there is a predetermined input to the stopper plate 25 through the reaction force plate 23, the clip 26 is deformed and disengaged from the opening 2a of the door inner panel 2, and the clip 26 is opened. 2a is penetrated. The stopper plate 25 is moved (displaced) to a position (second state) where it comes into contact with the door inner panel 2.

  The shape and size of the reaction force plate 23 can be set to an arbitrary shape such as a square plate shape or a conical shape depending on the type of vehicle and the space of the door 1.

  Between the stopper plate 25 and the reaction force plate 23, a compression coil spring 27 is provided as an urging means across these two members, and the reaction force plate 23 is moved to the door outer panel 3 side by the compression coil spring 27. Always energized. In this state, the pocket portion 21 is urged to the inside of the door trim 5 (on the door inner panel 2 side) to enter the housed state (normal time). In the stored state, the surface 21 a of the pocket portion 21 is biased and held so as to be flush with the surface of the door trim 5.

  During normal operation (during storage), as shown in FIG. 4, the pocket portion 21 is retracted and urged to the inside of the door trim 5 (door inner panel 2 side) to be stored. Since the surface 21 a of the pocket portion 21 is flush with the surface of the door trim 5, there is no protrusion on the side of the vehicle compartment 4, and the appearance is lowered or the space in the vehicle compartment 4 is reduced. There is no.

  When the pocket portion 21 is pulled out to store or take out small articles or books (when pulled out), the connecting rod 22 (reaction force plate 23) resists the spring force of the compression coil spring 27 as shown in FIG. ) Is moved to the compartment 4 side, and the pocket portion 21 is pulled out to the compartment 4 side.

  When the pocket portion 21 is pulled out to the full, the reaction force plate 23 comes into contact with the stopper plate 25 and is prevented from moving toward the vehicle compartment 4 side, and the amount of pull-out (movement amount) of the pocket portion 21 is restricted. When the storage and removal of small articles and books are completed, the reaction force plate 23 is moved to the door outer panel 3 side by the spring force of the compression coil spring 27, and accordingly, the pocket portion 21 is moved to the inside of the door trim 5 (door inner). It is moved to the panel 2 side and stored.

  In the vehicle door structure including the door pocket mechanism 11 described above, for example, when there is a predetermined input W from the outside to the inside of the passenger compartment 4 due to a side collision, as shown in FIG. 3 is displaced toward the compartment 4 side, and the reaction force plate 23 moves toward the compartment 4 side against the spring force of the compression coil spring 27. As the reaction force plate 23 moves, the connecting rod 22 moves to the compartment 4 side, so that the pocket portion 21 is pushed out to the compartment 4 side.

  When the input is transmitted by the reaction force plate 23 and the stopper plate 25 is pushed to the door inner panel 2 side (vehicle compartment 4 side), the position of the stopper plate 25 is changed between the stopper plate 25 and the door inner panel 2. The fitting between the restricting clip 26 and the opening 2a is released, and the movement (displacement) of the stopper plate 25 is allowed.

  As a result, the stopper plate 25 is moved (displaced) from the first state (position) to the second state (position) and pressed against the door inner panel 2 side. That is, the clip 26 is pushed into the opening 2a of the door inner panel 2 and moved (displaced) to a position where the stopper plate 25 abuts on the door inner panel 2 side.

  As a result, the restriction of the range of movement of the stopper plate 25 toward the vehicle compartment 4 with respect to the connecting rod 22 (reaction force plate 23) is released, so that the pocket portion 21 of the door pocket mechanism 11 is more than in the normal state when pulled out. Further, the pocket portion 21 is greatly protruded toward the passenger compartment 4, and the pocket portion 21 can be brought into contact with only the thigh portion 10 of the occupant 8 having relatively high impact resistance earlier so as to restrain the occupant 8.

  That is, when there is a predetermined input to the reaction force plate 23 (connecting rod 22) from the outside to the inside of the vehicle compartment 4 such as in a side collision, the pocket portion that comes into contact with the thigh 10 of the occupant 8 21 is projected and moved (displaced) to the vehicle compartment 4 side beyond the pulling amount (displacement amount) at the time of normal pulling, and the phase difference between the door trim 5 and the pocket portion 21 becomes larger.

  Therefore, the impact of the lumbar part 9 (pelvis: acetabulum and iliac bone) which is a part where the pocket part 21 is not in contact can be effectively reduced.

  Note that the input W from the outside of the passenger compartment 4 is transmitted from the door outer panel 3 to the connecting rod 22 via the reaction force plate 23, so that the direction of the input W varies (even if the range of the input W is wide). The connecting rod 22 can be accurately moved to project the pocket portion 21 largely toward the vehicle compartment 4 side.

  For this reason, the door pocket mechanism 11 having the pocket portion 21 that is pulled out and used on the side of the passenger compartment 4 is applied, and the load on the occupant 8 is received at a portion having higher impact resistance with respect to external input, and the portion having low impact resistance. In contrast, the occupant 8 can be restrained in a state where the load is accurately reduced.

  In the above-described embodiment, the connecting rod 22 is moved by the urging force of the compression coil spring 27 to maintain the movement position of the pocket portion 21, and the pocket portion 21 is flush with the surface of the door trim 5 at the normal time (when stored). However, the movement position of the pocket portion 21 can be held by the movement resistance of the connecting rod 22.

  A second embodiment of the vehicle door structure of the present invention will be described with reference to FIGS.

  7 is a schematic plan view showing the state of the door pocket mechanism according to the second embodiment, and FIG. 8 is a schematic plan showing the state of the door pocket mechanism when there is an input from the outside (side surface) of the passenger compartment. The visual status is shown. In addition, the same code | symbol is attached | subjected to the member of the same structure as 1st Embodiment shown in FIGS. Also, here, only the parts different in configuration from the first embodiment will be described, and description of the same parts as in the first embodiment will be omitted.

  As shown in FIG. 7, a front pocket portion 31 and a rear pocket portion 32 having a rectangular cross section are provided between the door inner panel 2 and the door trim 5 on the front and rear sides of the vehicle with the pocket portion 21 interposed therebetween. . The front pocket portion 31 and the rear pocket portion 32 are supported so as to be pulled out toward the vehicle compartment 4 side.

  A stopper 35 is provided on each of the front pocket portion 31 and the rear pocket portion 32 on the door inner panel 2 side (the vehicle outer side), and the stopper 35 is a door trim at the protruding end of the front pocket portion 31 and the rear pocket portion 32 on the vehicle compartment 4 side. Lock to the back side of 5. As a result, the amount of the front pocket portion 31 and the rear pocket portion 32 pulled out to the vehicle compartment 4 is restricted, and falling off from the door trim 5 is prevented.

  As shown in FIG. 7, the pocket portion 21, the front pocket portion 31, and the rear pocket portion 32 are urged and urged inside the door trim 5 (in the door inner panel 2 side) as shown in FIG. Has been. When storing or taking out small articles and books (when pulling out), the pocket portion 21, the front pocket portion 31, and the rear pocket portion 32 are pulled out toward the vehicle compartment 4 as necessary.

  For example, when there is a predetermined input W from the outside to the inside of the passenger compartment 4 due to a side collision, the door outer panel 3 is displaced toward the passenger compartment 4 as shown in FIG. The connecting rod 22 moves to the vehicle compartment 4 side, and the movement of the stopper plate 25 to the vehicle compartment 4 side is allowed, so that only the pocket portion 21 protrudes more to the vehicle compartment 4 side than in the normal drawer state. .

  Thereby, the pocket part 21 will protrude from the front pocket part 31 and the rear pocket part 32 to the compartment 4 side, and the thigh part 10 of the passenger | crew 8 is restrained early. That is, the front pocket portion 31 and the rear pocket portion 32 do not contact the occupant 8 before contacting the thigh 10. Accordingly, the thigh 10 of the occupant 8 is accurately restrained, and the impact (input) on the waist 9 (pelvis: acetabulum and iliac bone) is mitigated.

  In the above-described embodiment, since the pocket portion 21, the front pocket portion 31, and the rear pocket portion 32 are provided, the load on the occupant 8 is applied to the input from the outside in a state of having a sufficiently large door pocket. The occupant 8 can be restrained in a state of being accurately reduced.

  As described above, if the door structure of the vehicle of the present invention is used, the protection performance of the occupant 8 against input from the outside is applied by applying the door pocket mechanism that is pulled out to the passenger compartment side without using an impact absorbing member. Can be increased.

  In the above-described embodiments, the rear door structure has been described as an example. However, as long as the vehicle door has a drawer-type door pocket mechanism, the door structure of the present invention is applied not only to the front and rear parts of the vehicle. Is possible.

  INDUSTRIAL APPLICABILITY The present invention can be used in the industrial field of a vehicle door structure that can protect a passenger accurately by applying a door pocket when there is an input from the outside of the vehicle to the passenger compartment.
