  By the way, an extendable gas spring or the like that urges the front lid forward and upward from the vehicle body side may be connected to the rear surface side of the vehicle front lid. In this case, the front lid is biased by the gas spring and tilted to the front upper open position. In the open position, the gas spring extends to the longest length and restricts the upward tilt of the front lid to the open position.

  In the front lid described in Patent Document 1, when the gas spring is connected to the inner upper panel, an inertia force in the opening direction acts on the front lid when the tilting of the front lid is restricted to the open position by the gas spring. In addition, there is a possibility that an excessive load is applied to the inner upper panel due to the force in the direction opposite to the opening direction (closing direction) acting on the inner upper panel from the gas spring. Therefore, the inner upper panel is deformed while the operator repeatedly opens and closes the front lid, and the deformation of the inner upper panel causes the outer panel and the inner upper panel to be peeled off. There is a risk of deformation of the bonded portion.

  Accordingly, an object of the present invention is to provide a front structure of a vehicle that can prevent the deformation of the front lid caused by the tilting force applied to the front lid.

  In order to solve the above problems, the vehicle front structure of the present invention includes a front lid, tilting means, a regulating member, and a bracket. The front lid is supported near the upper edge of the opening formed on the front panel of the cab so that the upper edge is rotatable with respect to the front panel, and the front lid is tilted forward and upward to open the opening. It is possible to tilt between the open position and the closed position. The front lid has a plate member that faces the rear space of the opening from the front in the closed position. The plate member has a bead that protrudes forward in the closed position and extends in the vehicle width direction in the vicinity of the upper end edge of the plate member. The tilting means applies tilting power toward the open position with respect to the front lid. The regulating member is supported on the vehicle body side, one side below the upper edge of the opening and inside the opening, the other side is connected to the front lid, and the front lid is tilted by receiving the tilting force from the tilting means. Restrict the tilting range of the front lid to the open position. The bracket includes a fixed portion that is fixed to the front lid and a connecting portion that is connected to the other side of the restricting member. The fixing portion of the bracket is fixed in the vicinity below the rear bead at the closed position of the plate member.

  In the above configuration, since the tilting means applies tilting power toward the open position with respect to the front lid, when the regulating member regulates the tilt of the front lid to the open position (when tilting is restricted), the opening direction to the front lid Inertial force to act. One side of the restricting member is supported on the vehicle body side below the upper edge of the opening and inside the opening, and the other side is connected to the front lid. Therefore, when tilting is restricted, the restricting member opens the front lid on which inertial force acts. Is pulled in the opposite direction (closed direction), and a force in the closing direction acts on the plate member of the front lid from the regulating member via the bracket.

  Since the plate member has a bead extending in the vehicle width direction and the fixing portion of the bracket is fixed near the lower portion of the bead on the rear surface of the plate member, the upper portion of the fixed region of the plate member to which the fixing portion of the bracket is fixed The side is reinforced in the vehicle width direction by a bead. Therefore, even when a force in the closing direction is applied to the plate member from the regulating member via the bracket when the tilt is regulated, the plate member is hardly deformed and the front lid can be prevented from being deformed.

  Further, since the bead extends in the vehicle width direction in the vicinity of the upper end edge of the plate member, the bead reinforces the vicinity of the upper portion of the fixed region of the plate member and the outer edge portion of the plate member. That is, since the vicinity of the outer edge of the plate member and the upper portion of the fixed region of the plate member is reinforced with one bead, for example, when the plate member has an existing bead that reinforces the outer edge of the plate member, It is possible to reinforce the vicinity of the upper portion of the fixed region of the plate member using the existing bead without providing a bead.

  The front lid may include an inner panel as a plate member and an outer panel that is disposed in front of the inner panel in a closed position and joined to the inner panel.

  In the above configuration, since the plate member is the inner panel, the inner panel is reinforced by the beads, and the inner panel is hardly deformed when tilting is restricted.

  Moreover, since the inner panel is joined to the outer panel, the outer panel can be reinforced by the inner panel, and deformation of the outer panel at the time of tilt regulation can be prevented.

  The front lid may have an adhesive region where the outer panel and the inner panel are bonded to each other. The adhesion region extends in the vehicle width direction in the vicinity below the fixed region of the inner panel to which the fixing portion of the bracket is fixed.

  In the above configuration, the adhesion region between the outer panel and the inner panel extends in the vehicle width direction in the vicinity below the fixed region of the inner panel to which the fixing portion of the bracket is fixed. That is, in the fixed area of the inner panel, the upper side is reinforced by the bead and the lower side is bonded to the outer panel, so that the inner force due to the force in the closing direction acting on the fixed area of the inner panel when tilting is restricted. The deformation of the panel can also be suppressed by the outer panel, and the deformation of the front lid can be more suitably prevented.

  Further, since the adhesion region extends in the vehicle width direction, the force in the closing direction that acts on the fixed region of the inner panel when tilting is restricted is dispersed in the vehicle width direction and acts on the adhesion region. For this reason, for example, compared with the case where the outer panel and the inner panel each have a dotted adhesive region, it is possible to prevent a concentrated force from being input to a predetermined portion of the inner panel and the outer panel when tilting is restricted. Therefore, it is possible to prevent the front lid from being deformed by the force in the closing direction that acts when tilting is restricted.

  According to the present invention, it is possible to prevent the front lid from being deformed due to the tilting force applied to the front lid.

When the first open lever is operated, the wire 58 is pulled toward one side (the first open lever side), and the striker engaging portion 62 of the lock lever 54 of the left and right upper lock device 7 is connected to the torsion spring 63. Against the urging force, the base plate 53 rotates and moves away from the center of the striker insertion hole 56. When the striker engagement portion 62 of the lock lever 54 rotates in a direction away from the center of the striker insertion hole 56 of the base plate 53, the head portion 48b of the bolt shaft 48 of the left and right upper strikers 11 is engaged with the striker engagement of the lock lever 54. The locking by the portion 62 is released, and the left and right upper strikers 11 are moved forward by the urging force of the coil spring 50, and come out of the striker insertion hole 56 forward. As a result, the left and right upper strikers 11 are unlocked by the left and right upper lock devices 7. When the left and right upper strikers 11 are unlocked by the left and right upper lock devices 7, the front lid 6 is tilted forward and upward by the urging force of the gas spring 9, and the lower striker 12 is moved forward to lower the lock device. 8, the front lid 6 is slightly opened, and the front lid 6 is in a semi-open state in which tilting of the front lid 6 is restricted. In the half-open state, a gap in which a hand can be inserted is generated between the front lid 6 and the front opening 5.

  Next, the operator moves from the driver's seat to the front side of the cab 2 and inserts his hand into the rear space 27 of the front opening 5 through the gap between the front lid 6 and the front opening 5 in the half-open state. By operating the second open lever 64 (see FIG. 2) of the locking device 8, the locking of the lower striker 12 by the locking portion 79 of the lower locking device 8 is released. By unlocking the lower striker 12, the lock of the front lid 6 is completely released.

  When the lock of the front lid 6 is completely released, the front lid 6 is tilted forward and upward by the urging force of the gas spring 9. When the gas spring 9 is completely extended, the tilting of the front lid 6 toward the front upper side is restricted, and the front lid 6 reaches the open position and is in an open state.

  In the vehicle front structure 10 configured as described above, the gas spring 9 applies the tilting power to the open position by urging the front lid 6 to the open position, so that the gas spring 9 is fully extended. At the time of tilt regulation for regulating the tilt of the front lid 6 upward and upward, an inertia force in the opening direction acts on the front lid 6. Since one end of the gas spring 9 is supported with respect to the inner panel 4 on the vehicle body side and the other end is connected to the front lid 6, the gas spring 9 opens the front lid 6 in a direction opposite to the opening direction (closed) when tilting is restricted. Direction), and a force in the closing direction acts on the inner panel 14 of the front lid 6 from the gas spring 9 via the bracket 30.

  Since the bracket 30 extending in the vertical direction is fixed to the rear surface 28 of the inner panel 14, the bracket fixed region (the upper fixing portion 38 and the lower fixing portion 39 of the bracket 30 are fixed) of the inner panel 14 to which the bracket 30 is fixed. The upper and lower fixed regions are reinforced by the bracket 30 extending in the vertical direction. In addition, the inner panel 14 has an intermediate bead 34 extending in the vehicle width direction, and the bracket 30 is fixed to the rear surface 28 of the inner panel 14 in a state of crossing the intermediate bead 34. Reinforced by a medium bead 34 extending to Therefore, since the bracket fixed region of the inner panel 14 is reinforced in the vertical direction and the vehicle width direction, the inner panel 14 can be closed even if a force in the closing direction is applied to the inner panel 14 from the gas spring 9 via the bracket 30 when tilting is restricted. The panel 14 is not easily deformed, and deformation of the front lid 6 can be prevented.

  Further, since the upper bead 31 extending in the vehicle width direction at the upper edge of the inner panel 14 is disposed in the vicinity of the upper fixing portion 38 of the bracket 30, the bracket fixing region (upper fixing region on the upper side) ) Is reinforced by the upper bead 31. For this reason, the inner panel 14 is more difficult to be deformed by a closing force acting on the inner panel 14 from the gas spring 9 via the bracket 30 when tilting is restricted, and the front lid 6 can be further prevented from being deformed. .

  Further, an adhesive 43 is applied to the front surface of the middle bead 34 among the front surfaces 42 of the inner panel 14 so as to extend in the vehicle width direction along the middle bead 34, and the front surface of the middle bead 34 is formed by the adhesive 43. It is bonded to the rear surface 44 of the outer panel 13. For this reason, the deformation of the inner panel 14 due to the force in the closing direction acting on the bracket fixed region of the inner panel 14 when tilting is restricted can also be suppressed by the outer panel 13, and the deformation of the front lid 6 is more preferably prevented. can do.

  In addition, in the fixed region on the upper side of the inner panel 14 to which the upper fixing portion 38 of the bracket 30 is fixed, the upper vicinity is reinforced by the upper bead 31, and the lower vicinity is fixed to the outer panel 13 via an adhesive. Therefore, it is possible to suppress deformation of the inner panel 14 due to the force in the closing direction that acts on the fixed region on the upper side of the inner panel 14 when tilting is restricted.

  In addition, since the adhesion region between the front surface 42 of the inner panel 14 (the front surface of the middle bead 34) and the rear surface 44 of the outer panel 13 extends in the vehicle width direction along the middle bead 34, the bracket fixed region of the inner panel 14 when tilting is restricted. The force in the closing direction acting on is dispersed in the vehicle width direction and acts on the adhesion region. For this reason, for example, compared to the case where the outer panel 13 and the inner panel 14 each have a dotted adhesive region, a concentrated force is input to a predetermined portion of the inner panel 14 and the outer panel 13 when tilting is restricted. Since it can prevent, the deformation | transformation of the front lid 6 by the force to the closing direction which acts on the bracket fixed area | region of the inner panel 14 at the time of tilt control can be prevented.

  Further, since the inner panel 14 reinforced by the bracket 30 and the plurality of beads 26 is joined to the outer panel 13, the outer panel 13 can be reinforced by the inner panel 14, and the deformation of the outer panel 13 when tilting is restricted. Can be prevented.

  Further, since the upper fixing portion 38 of the bracket 30 is fixed near the lower portion of the upper bead 31 that reinforces the upper end edge portion of the inner panel 14, an outer edge portion (upper end edge) that is a joint portion between the inner panel 14 and the outer panel 13. The upper bead 31 for reinforcing the portion) can be used to reinforce the vicinity of the upper portion of the fixed region on the upper side of the inner panel 14.

  Therefore, according to this embodiment, it is possible to prevent the front lid 6 from being deformed due to the tilting force applied from the gas spring 9 to the front lid 6.
