An opening is formed in a portion of the hood frame corresponding to the upper side of the unlocking lever,
A vehicle is provided in which a plug capable of absorbing a load input from above the hood skin is engaged with the opening.

As described in claim 2, preferably, the plug has a weakened portion,
The load is absorbed by deforming and / or breaking the vicinity of the fragile portion in the plug.

According to a third aspect of the present invention, preferably, the plug is formed to have a flange portion facing the hood frame, a rising portion rising from the flange portion, and a convex shape upward from the rising portion. And an upper surface portion covering the upper surface of the rising portion,
The weak part is formed in the upper surface part and / or the rising part.

  As described in claim 4, preferably, the weakened portion is a slit, a hole or a notch.

  As described in claim 5, preferably, a material having a lower rigidity than the hood frame is used as a material of the plug, and the load is absorbed by deforming the plug.

  In the invention which concerns on Claim 1, the plug which can absorb the load input from the upper direction of a hood skin is latched by the opening part. Since the plug is locked in the opening, the operator's finger can be prevented from coming into contact with the opening. Further, the plug can absorb a load input from above the hood skin. For this reason, even if a pedestrian collides with a hood, this impact can be absorbed and it can be said that it is a plug with high pedestrian protection performance. In summary, the vehicle according to the present invention can be said to have a high pedestrian protection performance while covering the edge of the opening of the hood frame.

  In the invention according to claim 2, the plug has a weakened portion, and the load is absorbed by deforming and / or destroying the vicinity of the weakened portion of the plug. The load can be absorbed by a simple configuration of forming the fragile portion, which is beneficial.

  In the invention which concerns on Claim 3, the weak part is formed in the upper surface part and / or the standing part. That is, the fragile portion is formed at a portion avoiding the flange portion facing the hood frame. Thereby, the weak part currently formed in the other site | part is deform | transformed and destroyed, ensuring attachment to the hood frame of a flange part. As a result, the remaining crushing can be suppressed and the load can be reliably absorbed.

  In the invention which concerns on Claim 4, a weak part is a slit, a hole, or a notch. When a resin is used as a plug material, a slit or the like can be formed at the same time as the plug is formed by injection molding. Further, when a metal is used as a plug material, a slit or the like can be formed simultaneously with the formation of the plug by press forming. That is, a plug that absorbs a load by a slit or the like is preferable because it is easy to manufacture.

  In the invention according to claim 5, a material having lower rigidity than the hood frame is used as the material of the plug. By using such a material, it is possible to suppress an increase in the rigidity of the periphery of the opening. Compared with the case where a weak part is formed, a plug can be manufactured with a simpler mold, which is beneficial.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, Fr indicates the front, Rr indicates the rear, L indicates the left when viewed from the occupant, R indicates the right when viewed from the occupant, Up indicates the top, and Dw indicates the bottom.

  As shown in FIGS. 1 and 2, the front vehicle body 10 of the vehicle according to the first embodiment includes left and right front fenders 11 and 12 provided at left and right ends of the vehicle width, and these left and right front fenders. 11 and 12, a hood unit 13 provided between the hood unit 13, a bulkhead 14 provided below the hood unit 13, and a hood lock device 15 provided on the bulkhead 14.

  A radiator 18 is provided in front of the bulkhead 14. A bumper grill 19 is provided in front of the radiator 18. For example, the front body 10 of the vehicle is applied to a vehicle such as an RV (recreational vehicle) vehicle.

  The bulkhead 14 is a member that is provided below the hood unit 13 and partitions the front portion of the engine room 17. Such a bulkhead 14 has an upper member 23 bridged between left and right legs 21 and 22. A hood lock device 15 is provided at the center 23 a in the vehicle width direction of the upper member 23.

  In particular, as shown in FIG. 2, the hood lock device 15 is a well-known device used in a general vehicle. The hood lock device 15 includes a lock portion 25 provided at the vehicle width direction center 23 a of the upper member 23, a lock claw 26 provided at the lock portion 25, and a lock release lever 27. The lock claw 26 and the lock release lever 27 are integrally formed, and are rotatably provided on the lock portion 25 via a support shaft 28.

  The lock claw 26 is an arm that can be locked to the rod bottom 35 a of the striker 35. The lock release lever 27 is a lever that extends from the lock portion 25 toward the front of the vehicle body and is disposed below the hood unit 13.

  By swinging the lock release lever 27 upward, the lock claw 26 (lock portion 25) can be moved to the lock release position. By moving the lock claw 26 to the lock release position, the locked state of the striker 35 by the lock claw 26 is released.

  When the striker 35 is locked to the lock portion 25, the hood 32 is held in the closed position. When the striker 35 is released from being locked by the lock portion 25, the hood 32 is slightly raised and locked to the lock claw 26. In this state, the lock claw 26 is released from the striker 35 by operating the lock release lever 27 upward.

  When the lock claw 26 is separated from the striker 35, the locked state of the striker 35 by the lock claw 26 is released. The hood 32 is opened by lifting the hood 32 in a state in which the striker 35 is unlocked by the lock claw 26.

  The hood 32 includes a hood skin 41 that forms the outer surface of the front vehicle body 10, and a hood frame 42 that is provided on the back surface 41 a of the hood skin 41. The hood skin 41 and the hood frame 42 are formed integrally with each other by means such as caulking. The hood 32 is swingably supported by the frame (aggregate) of the front vehicle body 10 with the left and right rear end portions 32a (see FIG. 1) as fulcrums.

  An opening 45 is formed on the swing path of the lock release lever 27 in the hood frame 42. The opening 45 serves as an escape portion for the swinging lock release lever 27. A cap-like plug 50 is attached to the opening 45.

  The lock release lever 27 is covered with a hood 32. For this reason, when operating the lock release lever 27, the operator puts a finger between the hood frame 42 and the vehicle body (the upper surface of the bumper grill 19) and searches for the lock release lever 27 by groping. The lock release lever 27 and the opening 45 are provided close to each other. Since the plug 50 is locked to the opening 45, the operator's finger can be prevented from coming into contact with the edge of the opening 45. Such a plug 50 will be described in detail with reference to FIGS.

  As shown in FIG. 3 and FIG. 4, the plug 50 is a resin part having a substantially rectangular frame shape in plan view, and can be formed by injection molding. The plug 50 is formed in a substantially rectangular flange portion 51 facing the hood frame 42, a rising portion 52 rising from the flange portion 51, and a convex shape upward from the rising portion 52. And an upper surface portion 53 covering the upper surface of the rising portion 52.

  A plug claw portion 54 that sandwiches the hood frame 42 with the flange portion 51 is formed in the rising portion 52. At both ends of the plug claw portion 54, cutout portions 52a and 52a are formed in the vertical direction. Further, the plug claw portion 54 is formed with three retaining portions 54a that expand from the top to the bottom and serve to prevent the retaining.

  Two slits (fragile portions) 55 and 55 are formed in an X shape toward the opposite corners of the flange portion 51. These slits 55 and 55 can also be referred to as weak portions that reduce the rigidity of the plug 50. The slits 55, 55 are continuously formed from the rising portion 52 toward the upper surface portion 53, and are continuously formed up to a portion facing the rising portion 52. These slits 55 and 55 are formed at least in the corner portion of the rising portion 52 or the upper surface portion 53. That is, the slit 55 is formed at least at a portion where stress is easily concentrated.

  The upper surface portion 53 includes an upper surface taper portion 53a inclined toward the center and an upper surface portion lid portion 53b formed continuously from the upper surface taper portion 53a so as to cover the upper surface taper portion 53a. . The intersection of the slits 55 coincides with the center of the upper surface lid 53b. By covering the upper part of the rising part 52, the operator's finger is prevented from entering the hood (FIG. 2, reference numeral 32). Thereby, it can prevent that an operator's finger | toe contacts the components arrange | positioned inside the food | hood.

  The plug 50 can be engaged with the opening 45 so as to be pushed upward from below the opening 45. At both ends of the plug claw portion 54, cutout portions 52a and 52a having a cutout shape are formed. Thus, the plug claw portion 54 is configured to be easily bent. Since it is easy to bend, it can be easily attached to the hood frame 42. Further, in a state where the plug 50 is attached to the hood frame 42, the retaining portion 54a plays a role of retaining the plug 50. The operation of the plug 50 will be described in detail with reference to FIGS.

  As shown in FIGS. 5 and 6A, the head He of the pedestrian Mn may come into contact with the hood 32 when the pedestrian and the vehicle collide. In such a case, a load is applied from the hood skin 41 toward the hood frame 42.

  As shown in FIG. 6B, when the load reaches the plug 50, the slit 50 is formed in the plug 50, so that the deformation starts from the vicinity of the slit 55 having low rigidity. When a further load is applied, the plug 50 is broken as shown in FIG. Alternatively, as shown in FIG. 6 (d), the plug 50 falls off the hood frame 42.

  The plug 50 can absorb a load input from above the hood skin (41 in FIG. 5) by being deformed or broken. For this reason, even if the pedestrian Mn collides with the hood 32, this impact can be absorbed and it can be said that the plug 50 has high protection performance for the pedestrian Mn. In summary, the vehicle according to the present invention can be said to have a high pedestrian protection performance while covering the edge of the opening 45 of the hood frame 42.

  In addition, a slit 55 is formed in the plug 50, and the load is absorbed by deforming and / or destroying the vicinity of the slit 55 in the plug 50. The simple structure of forming the slit 55 can absorb the load, which is beneficial.

  Further, the slit 55 is formed in the upper surface portion 53 and / or the rising portion 52. That is, the slit 55 is formed at a portion that avoids the flange portion 51 facing the hood frame 42. Thereby, the slit 55 formed in the other part is deformed and destroyed while the attachment of the flange portion 51 to the hood frame 42 is ensured. As a result, the remaining crushing can be suppressed and the load can be reliably absorbed.

  In addition, a fragile portion is formed by the slit 55. When a resin is used as the plug material, the slit 55 can be formed at the same time as the plug 50 is formed by injection molding. When a metal is used as the plug material, the slit can be formed simultaneously with the molding of the plug by press molding. That is, the plug that absorbs the load by the slit is preferable because it is easy to manufacture.
