  According to the hood structure of a vehicle disclosed in Patent Document 1, when the hood is opened and closed, the link member and the hood are integrally connected by the second blocking portion of the connection member. Since the hood swings and displaces with the horizontal axis as a fulcrum, the hood can be opened and closed smoothly and the hood can be maintained in a stable closed state. In addition, when the traveling vehicle collides with an obstacle, the second blocking portion of the connecting member is broken according to the urging force of the lifting means, so that the link member has the first horizontal axis as a fulcrum. The upper oscillating displacement is allowed, and the hood is forcibly lifted away from the rear rear surface of the hood according to the oscillating displacement of the link member with the second horizontal axis as a fulcrum. There is an advantage that when the obstacle collides with the upper surface of the hood, a sufficient amount of downward displacement of the hood can be secured to effectively absorb the collision load.

  However, when the vehicle collides as described above, the connecting member that integrally connects the link member and the hood is dropped off by breaking the second blocking portion of the connecting member according to the biasing force of the lifting means. Therefore, when the rear end of the hood is lowered after the lifting means is actuated and re-traveled, unless the link member and the hood are integrally connected using a new connection member, the vibration during travel is determined. There is a problem that the rear part of the hood moves up and down, and abnormal noise is generated.

  The present invention has been made in view of the above-described problems, and releases the connection state between the link member supporting the rear portion of the hood and the hood as necessary, and connects the link member and the hood again. An object of the present invention is to provide a vehicle hood support structure that can be easily operated.

An engaging member supported by the hood in a cantilevered state; and an engaged portion provided on the link member so that the engaging member is detachably engaged. The rear part and the link member are connected together. When the collision accident occurs, the engagement member is elastically deformed according to the urging force of the push-up driving means to release the engagement state with the engaged portion, and the link member is moved to the hood. The engaging member supported by the hood in a cantilever state is elastically deformed by allowing the hood and the link member to be lowered to the initial position, and the engaging member is elastically deformed. The engagement portion is provided with an engagement guide portion that guides the engagement portion in a direction in which the hook portion provided at the tip of the engagement member is expanded, and the engagement portion. An extension portion extending in a direction opposite to the guide direction of the engagement member by the engagement guide portion, and the link member includes a pair of left and right side plates and both side plates. With the top plate connecting the top ends together What but that is formed into a U-shaped cross-section having an opening, extending portion of the engaged portion so as to cover the opening surface of the link member by the engaged portion is attached to the sides plates are disposed It is.

  According to the first aspect of the present invention, when a collision accident occurs in which the front end portion of the vehicle body abuts on an obstacle, the second pivotal support portion connects the front end portion of the link member and the front end portion of the hood side bracket. While maintaining the state, by disengaging the engaging member from the engaged portion and raising the rear portion of the hood, the hood is sufficiently lowered when the obstacle falls on the hood, etc. There is an advantage that it is possible to effectively relieve an impact load or the like acting on an obstacle by deforming the hood. After the occurrence of the collision accident, the rear portion of the hood that has been lifted as described above is pressed downward to swing and displace the link member with the first pivot portion as a fulcrum. The engaging member supported in a cantilevered state by the hood is elastically lowered by lowering the hood and the link member to the initial position while rotating and displacing the link member toward the rear lower surface of the hood with the fulcrum as a fulcrum. Since it can be deformed and re-engaged with the engaged part, it is easy to use the new connection member without complicated work such as connecting the link member and the hood side bracket. It can be returned to the state.

Further, when the hood is lowered to the initial position after the occurrence of the collision accident, the hook portion of the engagement member is guided and expanded by the engagement guide portion provided in the engaged portion, so that The engaging member can be engaged with the engaged portion with a light force and easily returned to the original state, and the engaging guide portion is reinforced by the extending portion to sufficiently ensure its rigidity. Therefore, even when the width dimension of the engaging member is different from the width dimension of the engaged portion, when the hook portion of the engaging member is engaged with or disengaged from the engaging guide portion, the engagement guide It is possible to effectively prevent the occurrence of a situation where the engaged portion is plastically deformed due to the stress concentration in the portion, and the link member is effectively prevented by the extended portion of the engaged portion. Without increasing the weight of the link member. The stiffness sufficiently secured, the rear end of the hood by the link member has advantages such as can be stably supported.

A widened portion 15 is formed at a rear portion of the vehicle body (see FIG. 5).

  The engaging member 8 has a width dimension set to a value slightly smaller than the width dimension of the link member 5, a mounting board 16 in which the insertion hole 19 of the mounting bolt 6 is formed, and a tip of the mounting board 16. And a hook portion 18 having an arcuate cross section projecting toward the front side of the vehicle body, that is, the installation portion side of the mounting substrate 16 is provided at the lower end of the hanging portion 17. It has been. The mounting board 16 of the engaging member 8 is sandwiched between the hood inner panel 1a and the upper surface plate 10 of the hood side bracket 7, thereby the rear end portion provided with the hanging portion 17 and the hook portion 18. Is supported on the rear lower surface of the hood 1 in a cantilever state protruding downward from the rear side of the hood side bracket 7.

  The link member 5 is formed in a U-shaped cross section having a lower surface opened by a pair of left and right side plates 20 made of a steel plate material and an upper surface plate 21 connecting upper ends of both side plates 20. Then, the base end portion of the side plate 20, that is, the rear side portion of the vehicle body is pivotally supported by the hinge bracket 3 via the first pivotal support portion 4, whereby the link member 5 is attached to the vehicle body via the hinge bracket 3. In addition to being connected, the first pivotal support 4 is supported as a fulcrum so as to be swingable.

  Further, the width of the upper surface plate 21 of the link member 5 is set to be smaller than that of the upper surface plate 10 of the hood side bracket 7, so that the space between the pair of left and right side plates 9 provided on the hood side bracket 7 is set. It is comprised so that the link member 5 may be inserted in. Further, the side plate 20 of the link member 5 is formed with a long hole 22 inclined forward and downward, and the second pivot part 13 made of the connecting pin is inserted into the long hole 22, whereby the second pivot part. 13, the distal end portion of the link member 5 and the front end portion of the hood side bracket 7 are connected to each other so as to be rotatable.

  When the link member 5 is inserted into the upper surface plate 21 of the link member 5 along the lower surface of the hood side bracket 7, the mounting bolt 6 is prevented from interfering with the link member 5, and the weight is reduced. Holes 23 and 24 for illustration are formed. Further, between the both side plates 20, an engaged portion 25 to which the engaging member 8 is detachably engaged is attached to a central portion in the front-rear direction by means such as welding. . The engaged portion 25 includes an engagement guide portion 26 having an arcuate cross section protruding toward the rear side of the vehicle body, and an extending portion 27 extending from the upper end portion of the engagement guide portion 26 to the front side of the vehicle body. The opening 27 (the lower surface) of the link member 5 is partially covered by the extended portion 27.

  Usually, the hook portion 18 of the engaging member 8 supported in a cantilevered state on the hood 1 is positioned below the engaging guide portion 26 of the engaged portion 25 provided on the link member 5. In addition, when the lower surface of the recessed portion 29 provided on the upper surface plate 10 of the hood side bracket 7 is brought into an engaged state in pressure contact with the upper surface plate 21 of the link member 5, the intermediate portion of the link member 5 and the hood 1. The rear part is integrally connected, and the front end part of the link member 5 and the front end part of the hood side bracket 7 are integrally connected to each other by the second pivotal support part 13. The hood 1 is opened and closed with one pivotal support 4 as a fulcrum.

  In other words, the restricting means including the engaging member 8 and the engaged portion 25 controls the front end portion of the hood 1 in a state in which the link member 5 is separated from the hood 1 with the second pivotal support portion 13 as a fulcrum. After releasing the locked state of the hood 1 by the lock mechanism provided outside the figure, the front end portion of the hood 1 in the closed position shown in FIGS. 1 and 7 is pushed upward, as shown in FIG. The hood 1 can be shifted to the open state by swinging and displacing in the direction in which the tip of the link member 5 is raised with the one pivotal support 4 as a fulcrum. In addition, the rear portion of the hood 1 can be moved up and down when the vehicle is running by locking the hood 1 in the lock position in a state where the rear portion of the hood 1 and the link member 5 are integrally connected via the restricting means. By restricting, the hood 1 can be locked in a stable locked state.

  Further, when it is detected by a sensor (not shown) that the front end of the vehicle body is in contact with an obstacle when the vehicle is running, the inflator or the like of the push-up drive means 31 disposed below the link member 5 is activated. Then, the telescopic pusher 32 is in an extended state, and the extended portion 27 of the engaged portion 25 provided on the link member 5 is biased upward, so that the first pivot 4 is used as a fulcrum. The front end portion of the member 5 is pushed upward, and the rear portion of the hood 1 is pushed upward with the lock portion at the front end as a fulcrum. As a result, the hook member 18 of the engagement member 8 supported by the hood 1 in a cantilever state is elastically deformed in a direction in which the hook portion 18 expands (a direction away from the engaged portion 25), thereby The engaged state between the hook portion 18 and the engaged portion 25 is released, and the link member 5 is allowed to swing and displace in the direction away from the hood 1 with the second pivotal support portion 13 as a fulcrum.

  While the front end portion of the hood 1 is locked in the closed position by the locking means as described above, the first pivotally supporting portion 4 is supported as a fulcrum according to the urging force of the push-up driving means 31 as shown in FIGS. Since the link member 5 is allowed to swing and displace, the rear portion of the hood 1 is pushed up, and the second pivotal support portion 13 is slid to the front side of the vehicle body along the long hole 22 of the link member 5. On the other hand, when the link member 5 swings and displaces with the first pivotal support 4 as a fulcrum, the distal end thereof rises.

  Next, when the rear part of the hood 1 pushed up by the push-up driving means 31 is pressed downward, the link member 5 is connected to the hood side bracket 7 and the link member 5 via the second pivotal support part 13. 1, while the rear portion of the hood 1 is supported, the link member 5 swings and displaces with the first pivotal support portion 4 as a fulcrum, so that the distal end portion of the link member 5 is moved to the position shown in FIG. Lower to the initial position shown. When the hood 1, the engaging member 8, and the link member 5 are each lowered to the initial position in this way, the lower end surface (inclined surface 18 a) of the hook portion 18 provided on the engaging member 8 becomes the engaged portion 25. The hook portion 18 of the engaging member 8 is moved under the engagement guide portion 26 while being elastically deformed and is engaged with the engaged portion 25 while being pressed against the upper end surface of the provided engagement guide portion 26. As a result, the link member 5 is returned to the state in which the link member 5 is integrally connected to the rear portion of the hood 1 by the restricting means including the engaging member 8 and the engaged portion 25.

  The base end portion is pivotally supported with the hood 1 disposed at the front portion of the vehicle body and supported to be opened and closed as described above, and the first pivot portion 4 provided on the vehicle body as a fulcrum, A link member 5 having a tip pivotally supported by a second pivot 13 provided on the hood 1 as a fulcrum, and a link member 5 supported in a cantilevered state on the hood 1; Since the restricting means including the engaged portion 25 provided on the member 5 is configured to restrict the swinging displacement of the link member 5 in the direction away from the hood 1 with the second pivotal support portion 13 as a fulcrum, Normally, the hood 1 can be opened and closed smoothly with the first pivotal support 4 provided on the hinge bracket 3 as a fulcrum while the rear portion of the hood 1 is connected to the link member 5, and when the vehicle is running The rear of the hood 1 And prevent downward movement has the advantage of retaining the hood 1 in a stable locked state.

  When a collision accident occurs in which the front end portion of the vehicle body abuts on an obstacle, the second pivot support portion 13 maintains the connection state between the distal end portion of the link member 5 and the front end portion of the hood side bracket 7. Then, the push-up drive means 31 is actuated to urge the link member 5 upward, whereby the engaging member 8 is disengaged from the engaged portion 25 and the intermediate portion of the link member 5 and the rear end of the hood side bracket 7 are moved. The connection state with the part can be released. Therefore, as shown in FIGS. 9 and 10, the hood 1 is lowered when the obstacle falls on the hood 1 by raising the rear portion of the hood 1 in accordance with the urging force of the push-up driving means 31. There is an advantage that a sufficient amount can be secured and the impact load or the like acting on the obstacle can be effectively reduced by deforming the hood 1.

  In addition, after the occurrence of the collision accident, the rear portion of the hood 1 that has been lifted as described above is pressed downward to cause the link member 5 to swing and displace with the first pivotal support portion 4 as a fulcrum. The hood 1 is cantilevered by lowering the hood 1 and the link member 5 to the initial position while rotationally displacing the link member 5 in the direction of approaching the rear lower surface of the hood 1 with the second pivot portion 13 as a fulcrum. Since the supported engaging member 8 can be elastically deformed and re-engaged with the engaged portion 25, the link member 5 and the hood side bracket 7 are connected using a new connecting member, etc. It is possible to easily return to the original state without requiring complicated work. Therefore, the push-up drive means 31 is activated when the accident occurs, or a malfunction occurs in the push-up drive means 31 so that the hood 1 whose rear end is raised is returned to the original state, and then the vehicle is driven. When the vehicle is driven, the rear portion of the hood 1 moves up and down by the above-mentioned restricting means, and the hood 1 is held in a stable locked state. There is an advantage that it can be effectively prevented with a simple configuration.

Further, the hook portion 18 when reengaging the arcuate cross section of the engaging guide portion 26 which protrudes toward the rear side of the vehicle body is provided on the engaged portion 25, the engagement member 8 in the engaged portion 25 Since the guide portion 26 is used as a guide surface for guiding in the direction in which the hood 1 is expanded, as shown in FIG. By sliding the engagement member 8 along the upper end surface of the engagement guide portion 26 provided in the joint portion 25, the hook portion 18 can be smoothly shifted to the lower side of the engagement guide portion 26 to facilitate the operation. There is an advantage that it can be re-engaged.

  In particular, in the above-described embodiment, the hook portion 18 of the engaging member 8 is formed in a cross-sectional arc shape protruding toward the front side of the vehicle body, so that the engaging member 8 is re-engaged with the engaged portion 25. Since the engaging guide surface, that is, the inclined surface 18a extending to the rear side of the vehicle body is formed at the lower end portion of the hook portion 18, as shown in FIG. 9, the rear portion of the hood 1 at the raised position is pressed downward.
