Description

  The present invention relates to a vehicle opening / closing body structure applied to, for example, a vehicle tailgate.

  A tailgate is mentioned as one of the opening / closing bodies of a vehicle, and the tailgate opens and closes an opening of a cargo compartment. For example, a tailgate having a hinge portion provided at the upper part of a door frame is formed by joining an outer panel and an inner panel, and a latch member is attached to the lower part of the tailgate. The latch member is a member that has a function of engaging the striker on the vehicle body side to lock the tailgate and a function of releasing the lock, and is a member that increases in weight. For this reason, a reinforcing latch reinforcement is joined to the inner panel of the tailgate at a portion where the latch member is attached (see, for example, Patent Document 1).

  Generally, when a gate is opened and closed, an inertial force acts on a lower side (an end side opposite to the hinge portion) of the tailgate. In particular, when the gate is closed, the tailgate's own weight is also applied, and a very large inertial force (force in the gate closing direction) acts. Also, the reaction force (force in the gate opening direction) due to the reaction when the tailgate closes It acts on the lower end of the tailgate. Therefore, these forces greatly influence the latch member mounting portion and the latch reinforcement.

  Although the latch reinforcement is joined to the inner panel by welding or the like, the latch gate is not only subjected to the force in the opening / closing direction as described above but also the weight of the latch member every time the tail gate is opened / closed. Rigidity is maintained so that it will not be damaged even if a force such as an inertial force due to opening and closing of the door is applied. Further, when the tailgate is closed, the outer panel and the inner panel on the end side of the tailgate bend in the opening / closing direction due to the influence of the inertial force and reaction force.

  That is, when the gate is closed, first, the inner panel is bent so as to move in the gate closing direction by inertial force, and immediately thereafter, the inner panel is bent in the gate opening direction by the reaction force due to the reaction of closing the gate. For this reason, since the latch reinforcement in which the rigidity is maintained is greatly affected by the deflection of the inner panel, the stress concentrates on the joint surface (welded part, etc.) between the latch reinforcement and the inner panel, and shear force and peeling force are applied. .

  The latch reinforcement of the tailgate can prevent damage due to the attachment of the latch member by securing the rigidity, but if the rigidity is too high, the joint surface (welded part) due to the deflection of the inner panel accompanying the opening and closing of the tailgate. The shearing force and the peeling force applied to the above are increased. If the latch reinforcement is made to follow the deflection of the inner panel as the tailgate opens and closes while keeping the overall rigidity of the latch reinforcement to a minimum, stress will concentrate on the latch member mounting area and damage will likely occur. Become.

  As described above, the latch reinforcement provided in the tailgate is currently required to have contradictory functions such as a function of ensuring rigidity and a function of reducing the force acting on the joint surface. In particular, since welding has lower rigidity against peeling force than shearing force, the joint surface (welded part, etc.) peels off due to the deflection of the inner panel that occurs when the tailgate opens and closes while securing the rigidity of the latch reinforcement. There is a need to reduce force.

  The situation is the same for the tailgate of a vehicle in which the hinge part is provided on the side part of the door frame, and the same situation occurs in the opening and closing body such as the door panel provided with the latch member. Is the current situation.

  5, reference numeral 52 denotes a weather strip provided on the vehicle body 51, and 53 denotes a bumper at the rear of the vehicle.

  Details of the latch reinforcement 30 will be described with reference to FIGS.

  As described above, in the latch reinforcement 30, the base surface reinforcing portion 31 and the edge wall surface reinforcing portion 32 are continuously provided along the inner shape of the latch attaching portion 20 provided on the lower end surface portion 13 of the inner panel 11. A bendable portion 33 is formed between the base surface reinforcing portion 31 and the edge wall surface reinforcing portion 32 so as to extend from the base surface reinforcing portion 31 and connect the two. An extension wall portion 34 is formed at the end opposite to the bending allowance portion 33 so as to rise upward along the shape of the inner panel 11.

  The bending allowance portion 33 includes a horizontal portion 36 in which the base surface reinforcing portion 31 extends to the outer panel 12 side of the mounting base surface portion 21 of the latch mounting portion 20, and an edge of the latch mounting portion 20 of the inner panel 11. It is formed by a folded portion 37 that is folded back toward the wall surface portion 22 and is continuous with the edge wall surface reinforcing portion 32. The bending allowance portion 33 forms a substantially triangular closed cross section with the latch mounting portion 20 of the inner panel 11, the horizontal portion 36 of the bending allowance portion 33, and the folded portion 37, thereby providing a space between the inner panel 11. Both the base surface reinforcing portion 31 and the edge wall surface reinforcing portion 32 are connected to each other.

  In the bending allowance portion 33, a first joint 38 is formed at a continuous portion of the horizontal portion 36 and the folded portion 37, and a second joint 39 is formed at a continuous portion of the folded portion 37 and the edge wall surface reinforcing portion 32. It is comprised so that it may be formed.

  The latch reinforcement 30 has a space between the inner panel 11 such as the bending allowance portion 33 so that there is no play between the base surface reinforcing portion 31 and the edge wall surface reinforcing portion 32. By adopting such a configuration, bending of the edge wall surface reinforcing portion 32 with respect to the base surface reinforcing portion 31 can be allowed. In addition, by forming the first joint 38 and the second joint 39 so that the bending allowance portion 33 can be easily deformed, the edge wall surface reinforcing portion 32 can actively follow the bending of the inner panel 11. .

  Further, flange portions 35 are continuously formed on both side edges from the extending wall portion 34 of the latch reinforcement 30 to the base surface reinforcing portion 31 and the horizontal portion 36 of the bending allowance portion 33. The flange portion 35 is formed so as to stand up in a direction intersecting with the surface of the horizontal portion 36 of the extending wall portion 34, the base surface reinforcing portion 31, and the bending permission portion 33.

  Since flange portions 35 are continuously formed on both side edges from the extending wall portion 34 of the latch reinforcement 30 to the base surface reinforcing portion 31 and the horizontal portion 36 of the bending allowance portion 33, the extending wall portion 34 The rigidity of the base surface reinforcing part 31 and the part up to the horizontal part 36 of the bending allowance part 33 can be kept high. For this reason, even if the tailgate 2 (see FIGS. 1 and 2) is opened and closed while the latch member 4 (see FIGS. 3 to 5) is fixed, a crack or the like may occur in the fixing portion due to the inertial force of the latch member 4. No damage will occur.

  Next, the action of the force generated when the tailgate 2 is closed and the function of the bending allowance portion 33 of the latch reinforcement 30 will be described in detail with reference to FIGS.

  When the tailgate 2 is closed by closing the tailgate 2 (rotation in the direction of the arrow in FIG. 5), an inertial force (force in the direction of the arrow A in FIG. 6) is first applied to the end of the tailgate 2. Immediately thereafter, a reaction force in the direction opposite to the inertial force (force in the direction of arrow B in FIG. 6) acts due to the reaction when the tailgate 2 is closed. By these actions, the edge wall surface 22 of the inner panel 11 is bent together with the outer panel 12 in the arrow A direction (gate closing direction) in FIG. 6 and then bent in the arrow B direction (gate opening direction) in FIG. Mu

  When the edge wall surface portion 22 bends in the direction of arrow A (gate closing direction) in FIG. 6, peeling force is applied to the joint surface (welded portion) between the edge wall surface portion 22 and the edge wall surface reinforcing portion 32 of the latch reinforcement 30. When the edge wall surface portion 22 is bent and bent in the arrow B direction (gate opening direction) in FIG. 6, the edge wall surface portion 22 is pushed by the edge wall surface portion 22, so that the mounting base surface portion 21 of the inner panel 11 is latched. Stress concentrates at the joint portion (around the weld nut) with the base surface reinforcing portion 31 of the reinforcement 30.

  The latch reinforcement 30 is provided with a bending allowance portion 33 between the base surface reinforcing portion 31 and the edge wall surface reinforcing portion 32 against the influence of the bending of the inner panel 11. This is achieved by allowing the edge wall surface reinforcing portion 32 to bend with respect to the reinforcing portion 31.

  That is, when the edge wall surface portion 22 bends in the direction of arrow A (gate closing direction) in FIG. 6, the bending allowance portion 33 is deformed and bent at the first and second joints 38 and 39, and the edge The wall surface reinforcing portion 32 can move in the direction of arrow A (gate closing direction) in FIG. 6 following the movement of the edge wall surface portion 22. Thereby, the peeling force which arises in the joint surface (welding part) of the edge wall surface part 22 and the edge wall surface reinforcement part 32 can be suppressed.

  Further, even when the edge wall surface portion 22 bends in the direction of arrow B (gate opening direction) in FIG. 6, the bending allowance portion 33 is deformed at the first and second joints 38 and 39 and the edge wall surface reinforcing portion. 32 can follow the arrow B direction (gate opening direction) in FIG. Thereby, the input from the edge wall surface part 22 can be absorbed, and it can suppress that stress concentrates on the joint surface (weld nut periphery) by the side of the base surface reinforcement part 31 side.

  As described above, the tailgate structure of the present invention is configured to be able to flexibly follow the bending of the inner panel 11, so even if the latch reinforcement 30 has high rigidity, the inner panel 11 The peeling force (stress on the spot welded part or bolt joint) acting on the joint surface (spot weld point or bolt joint) between the latch reinforcement 30 and the latch reinforcement 30 is reduced.

  Accordingly, the peeling force (spot) acting on the joint surface between the inner panel 11 and the latch reinforcement 30 is secured in a state where rigidity capable of suppressing damage such as cracks at a portion to which the latch member 4 (see FIGS. 3 to 5) is attached is secured. The stress on the welded part or bolted part) can be greatly reduced.

  Further, in the latch reinforcement 30 of the present invention, the flange surface 35 is continuously formed on both side edges extending from the extending wall portion 34 to the base surface reinforcing portion 31 and the horizontal portion 36 of the bending allowance portion 33, whereby the base surface It is set as the structure which can improve the rigidity of the reinforcement part 31 and can further improve the rigidity of the site | part to which the latch member 4 is attached.

  Thereby, it can be set as the tailgate 2 provided with the latch reinforcement 30 which has the function to ensure the rigidity, and the function to reduce the force which acts on a joining surface. Since it is not necessary to increase the rigidity of the edge wall surface reinforcing portion 32 with respect to the bending of the inner panel 11 more than necessary, the plate thickness of the latch reinforcement 30 can be suppressed to a minimum thickness, and the weight can be reduced. be able to. Further, since the stress in the peeling direction can be reduced, it is not necessary to reinforce the welded portion of the joint surface with an adhesive or the like.

  The bendable portion 33 is not limited to the shape of the illustrated example as long as it has a space between the inner panel 11 and the end wall surface reinforcing portion 32 is easily bent with respect to the base surface reinforcing portion 31. . For example, depending on the shape of the inner panel 11 and the outer panel 12 and the positional relationship between them, a node is formed at a position higher than the upper surface of the end of the base surface reinforcing portion 31, or the end of the base surface reinforcing portion 31 is placed on the outer panel. It is possible to apply a shape such as forming the first joint 38 at a position that extends to the 12 side and is lower than the upper surface of the base surface reinforcing portion 31. Moreover, the shape which the bending | flexion permission part 33 curved as a whole instead of the shape which turned the site | part of the 1st joint 38 may be sufficient.

  In the above-described embodiment, the example in which the hinge portion is provided in the upper portion of the door frame and applied to the tailgate that opens and closes around the horizontal axis has been described. However, the hinge portion is provided in the side portion of the door frame and the vertical axis. It is also possible to apply to a tailgate that opens and closes around. In addition, as long as the opening / closing body of the vehicle has a latch reinforcement joined to the inner panel, it can also be applied to an opening / closing body such as a door panel other than the tailgate. The latch member 4 is configured to electrically unlock the engaging portion 7 by driving the actuator in accordance with the operation of the gate handle 6. The structure which connects the part 8 may be sufficient.

  The present invention can be used, for example, in the industrial field of a vehicle opening / closing structure applied to a tailgate or the like of a vehicle.
