Description

TECHNICAL AREA

The present invention relates to an articulated arm arrangement for a vehicle front hood.

TECHNICAL BACKGROUND

For example, Patent Document 1 discloses a bonnet hinge attached to a bonnet above the engine compartment of a vehicle body. With this front hood hinge, the front hood is pivotally mounted on the vehicle body side. Specifically, in Patent Document 1, a vehicle-body-side joint member fixed to the side of the vehicle body has a first support arm with a bent portion and a second support arm whose lower end is not fixed to an upper fender member.

According to Patent Document 1, when a shock load of a colliding body acts, the second support arm falls inward from the upper fender member in the vehicle transverse direction. A limitation of the deformability of the first support arm down, caused by the second support arm, can be avoided. In addition, the impact load acting on the colliding body can be reduced because the first support arm with the bent portion can be easily deformed downward.

OVERVIEW OF THE INVENTION

TASKS TO BE SOLVED BY THE INVENTION

When a vehicle hood is opened and closed or a vehicle is running, a load acts on an upper fender member in the vertical direction. When the upper wall of the upper fender member at the vehicle outside end is connected to the vertical wall as disclosed in Patent Document 1, the load in the vertical direction becomes a load in the separating direction of the connecting portion between the upper wall and the vertical wall. For this reason, in the structure disclosed in Patent Document 1, it is necessary to further improve the rigidity against the load acting on opening and closing the bonnet.

In the vehicle, devices such as a powertrain (hereinafter simply referred to as "devices") are also mounted under the bonnet. Accordingly, in a structure in which the articulated arm collapses inward in the vehicle transverse direction at the time of collision, there is a possibility that the deflection required for absorbing an impact due to deterioration by the devices can not be sufficiently ensured. or that the devices are damaged.

In view of these problems, it is an object of the present invention to provide an articulated arm assembly for a vehicle hood which has a high rigidity against a load in the vertical direction acting at the time of opening and closing the hood and while driving a vehicle.

MEANS TO SOLVE THE TASK

The object is achieved by a preferred embodiment of an articulated arm assembly for a vehicle hood according to an aspect of the present invention, which comprises: an articulated arm supporting a front hood covering an engine compartment in the front part of a vehicle body; a hinge bracket to which the hinge arm is pivotally mounted; a vehicle body side panel forming a side surface of the engine compartment; and a cowl side panel that connects the hinge bracket to the vehicle body side panel, and the cowl side panel includes: a first connection surface to which the hinge bracket is connected; and a second connection surface that extends upward from an end with respect to the vehicle transverse direction inside end of the first connection surface and is connected to the vehicle body side panel.

EFFECT OF THE INVENTION

According to one aspect of the present invention, it is possible to provide an articulated arm assembly for a vehicle hood which has a high rigidity against a load in the vertical direction acting at the time of opening and closing the bonnet and while the vehicle is running.

EMBODIMENTS OF THE INVENTION

An articulated arm assembly for a vehicle hood according to an embodiment of the present invention includes: an articulated arm that supports a front hood that covers an engine compartment in the front part of a vehicle body; a hinge bracket to which the hinge arm is pivotally mounted; a vehicle body side panel forming a side surface of the engine compartment; and a cowl side panel connecting the hinge bracket to the vehicle body side panel, and the cowl side panel including: a first connection surface to which the hinge bracket is connected; and a second connection surface extending upward from a vehicle-width-direction-side end of the first connection surface and connected to the vehicle-body side panel.

In the embodiment described above, the hinge bracket, which rotatably supports the articulated arm, is connected to the vehicle body side panel via the cowl side panel. In this case, the cowl side panel on the second connection surface, which extends in the vertical direction, connected to the vehicle body side panel. In this configuration, a load in the vertical direction acting at the time of opening and closing the bonnet or during the running of the vehicle becomes a load in the shear direction with respect to the connecting portion of the cowl side panel and the vehicle body side panel. Accordingly, it is possible to achieve high rigidity against the acting load at the time of opening and closing the bonnet or while driving.

The cowl side panel may further include a sloped wall that slopes downwardly in the vehicle transverse direction outward from the vehicle-to-vehicle outside-out end of the first joint surface, the joint arm may have a front-side portion extending in the vehicle front-rear direction and fixed to the front hood and a rear side portion that extends rearward from the front side portion, is curved so as to bulge downward, and fixed to the hinge bracket, and a lower end of the rear side portion may be disposed at a position which overlaps the inclined wall when viewed from above.

Because the articulated arm is located at a position that overlaps the sloped wall when viewed from above, in a crash of a collision body with the front hood above the articulated arm, the load is transferred from the front hood to the articulated arm. Due to this load, the lowermost point of the articulated arm contacts the inclined wall of the cowl side panel. In this configuration, it is possible to ensure a downward deflection of the articulated arm, which corresponds to the amount of lowering of the inclined wall toward the vehicle lower side, and thereby to obtain the effect that the impact load of the collision body can be absorbed.

In addition, as soon as the lower end of the articulated arm comes into contact with the inclined wall, the articulated arm and the articulated bracket buckle outward in the vehicle transverse direction, with the inclined wall serving as a guide. The impact absorption effect is increased in this way that the deflection or distance is increased by the buckling of the articulated arm. In addition, since the side of the second connecting surface of the vehicle inner side of the load acting from above offers more resistance than the hinge bracket and has a higher rigidity, the buckling of the articulated arm can be further promoted to the outside.

The aforementioned hinge bracket may be connected to the inside of the vehicle with respect to the hinge arm and may include a flange bent to the inside of the vehicle and a bead extending upwardly and rearwardly of the vehicle in a central portion of the hinge bracket. In this embodiment, the flange and the bead withstand a load acting from the upper side of the vehicle. For this reason, since the deformation is minimized, it is possible that the lower end of the articulated arm is reliably in contact with the inclined wall. Also, the side of the second connection surface has a high rigidity against a load acting from above and thus it is possible to buckling the Articulating bracket and the articulated arm to the outside to further favor.

When viewed from above, at a position where the lower end of the rear side portion and the inclined wall overlap each other, a reinforcement may be connected to the rear side of the cowl side panel. Because in this way the position at which the lower end of the articulated arm comes into contact with the cowl side panel is reinforced by the reinforcement, the cowl side panel serves as a guide for the articulated arm, which can thus buckle sufficiently to the outside.

embodiments

As in 1 is shown, is on the front of the vehicle body, the front hood 102 arranged, which has a drive unit mounting space or engine compartment 103 covers (see 2 ). The mudguard sheets 104 , which form the side surfaces of the vehicle body, are below the front hood 102 arranged. A splashboard side panel 106 (please refer 2 ), which is a vehicle body side panel, which is the side surface of the engine compartment 103 is on the inside of each fender panel 104 arranged.

As in 1 is shown, the front hood is the front hood 102 between the bonnet 102 and a windshield (not shown) a cowl top panel 152 arranged, which is a molded part. On the sides of the cowl top panel 152 are fender tops 154 arranged. The front hood 102 out 1 is from the articulated arm 110 out 2 supported, and the fender tops 154 serve as moldings, each one of the articulated arms 110 cover.

As in 2 is shown is the articulated arm 110 pivotable on the upper part of a hinge bracket 120 attached, in relation to the articulated arm 110 connected to the vehicle interior. As in 2 shown are the articulated arm 110 and the front hood 102 (please refer 1 ), which is the articulated arm 110 supports a joint 122 pivotable. The hinge bracket 120 is over a cowl side panel 130 to an outer cowl side member 108 tethered.

3 is a perspective view of the articulated arm assembly for a vehicle hood 100 out 2 , In 3 becomes the arrangement 100 inside the vehicle from the front. As in 3 is shown is a cowl lower panel 156 inside of the dashboard side panel 106 arranged. A fender standing plate 158 is front of the dashboard side panel 106 arranged. The fender standing plate 158 forms together with the outer cowl side element 108 a closed cross section. As in 3 is shown is the front end of the cowl lower panel 156 with the fender standing plate 158 via a fender plate holder 160 connected. The hinge bracket 120 is with a first interface 132 (please refer 4 ) of the cowl side panel 130 connected.

4 is a cross-sectional view of 2 along the line AA , 5 is a perspective view of the cowl side panel 130 out 2 , In 4 are on average AA out 2 the cowl top sheet 152 and the fender top 154 shown, but it is understood that in place of the cowl top sheet 152 and the fender shell 154 at a position at the front of the cut AA the front hood 102 is arranged.

As in the 4 and 5 is shown has the cowl side panel 130 This embodiment, a first connection surface 132 and a second connection surface 134 on. The first interface 132 is a section with which the hinge mount 120 connected is. The second interface 134 is a portion which is from a vehicle-width direction inside end of the first connection surface 132 goes up and with the bulkhead side panel 106 connected is.

At the upper section of the dashboard side panel 106 is a dashboard side reinforcement 162 arranged. As a result, the splashboard side panel 106 from the bulkhead side reinforcement 162 and the second connection surface 134 of the cowl side panel 130 flanked. Through this connection with the second interface 134 , which runs in the vertical direction, becomes a load in the vertical direction at the time of opening and closing the bonnet 102 acts, thus to a load in a shear direction 135 , Accordingly, it is possible to have a high joint strength against that at the time of opening and closing the bonnet 102 to achieve acting load.

On the outside of the vehicle, the dashboard side reinforcement 162 is a cowl side damper 164 extending from the vehicle exterior of the dash panel side reinforcement 162 extends upwards. The cowl side damper 164 causes an effect to absorb a load caused by an impact from above by deforming.

Characterized in that, as mentioned above, the joint strength of the cowl side panel 130 and the splashboard side panel 106 in 4 is increased, it is also possible the articulated arm 110 and also the front hood 102 stable to wear. That is, the rigidity of the support structure of the bonnet 102 is improved. Accordingly, the hem is between the front hood 102 and the splashboard side panel 106 stabilized and the appearance can thus be improved.

As in 4 is shown, in the above embodiment, the joint or the connection point (the second connection surface 134 ) of the splashboard side panel 106 and the cowl side panel 130 above the joint or the connection point (the first connection surface 132 ) of the hinge bracket 120 and the cowl side panel 130 arranged. In this embodiment, a load is generated at the time of opening and closing the bonnet 102 acts reliably as a load in the shearing direction with respect to the second connection surface 134 transfer. Accordingly, the joint strength of the cowl side panel 130 and the splashboard side panel 106 improved, the hem between the front hood 102 and the splashboard side panel 106 is stabilized and the appearance can thus be improved.

As in 4 and 5 is shown, includes the cowl side panel 130 in the arrangement 100 This embodiment also has a sloping wall 136 , a third interface 138 and a front wall 139 , The inclined wall 136 is a portion that extends in its course from the vehicle-width direction outside end of the first connection surface 132 is inclined downwards in the vehicle transverse direction. The third interface 138 is a portion that is different from the vehicle width direction outside end of the inclined wall 136 extends to the outside of the vehicle. As in 3 shown is the front wall 139 also with a fender extension plate 166 connected.

The following is the behavior in a collision of a body with the front hood 102 described. The load position is assumed to be a position at which the front hood 102 and the articulated arm 110 overlap when viewed from below. In the initial stage of an impact of a collision body is due to the collision of the body with the front hood 102 acting load from the front hood 102 on the articulated arm 110 transfer. Because of this load comes the articulated arm 110 with the inclined wall 136 of the cowl side panel 130 in contact.

Once the articulated arm 110 with the inclined wall 136 comes in contact, the articulated arm bends 110 in the last phase of impact of the collision body together with the hinge bracket 120 in the vehicle transverse direction to the outside, wherein the inclined wall 136 serves as a guide. By this process, it is possible to ensure a larger deflection for absorbing the impact and to improve the impact absorbing properties with respect to the collision body.

It should be noted that the articulated arm 110 from the load acting through the bonnet 102 is compressed further. The cowl side panel 130 However, it has a high rigidity and is with the outer cowl side member 108 connected, which has high rigidity, and thus occurs almost no deformation. In the embodiment of this embodiment, the front hood extends 102 in the vehicle transverse direction also further outward than the displacement distance of the articulated arm 110 , In terms of the articulated arm 110 Therefore, for example, the articulated arm mounted on the right side of the vehicle buckles, mounted on the opposite side 110 not together with the articulated arm mounted on the left side of the vehicle 110 inwards when a collision body with the surroundings of the hinged on the left side of the vehicle articulated arm 110 collided.

6 is a detail view of the Gelenkarmanordnung for a vehicle hood 100 out 2 , 6 (a) shows a state in which the arrangement 100 out 2 viewed from above, and 6 (b) shows a state in which the arrangement 100 out 2 viewed from the side of a point outside the vehicle. As in 2 and 6 is shown includes the articulated arm 110 This embodiment, a front-side section 112 and a rear section 114 , The front section 112 extends in the vehicle longitudinal direction and is on the front hood 102 attached. The rear section 114 is a section of the front section 112 is rearward and curved so that it is bulged downward, and is on the hinge bracket 120 attached.

As in 6 is shown, in this embodiment, a lower end P of the rear-side portion 114 of the articulated arm 110 arranged at a position where they viewed from above the inclined wall 136 overlaps. If a collision body with the front hood 102 collides, becomes a load from the front hood 102 on the articulated arm 110 transfer. As a result of this load comes the lower end P of the rear portion 114 , which is the lowest point of the articulated arm 110 represents, in contact with the inclined wall 136 of the cowl side panel 130 , Because the inclined wall 136 of the cowl side panel 130 in its course from the vehicle transverse direction outside end of the first connection surface 132 is inclined downwards in the vehicle transverse direction, it is possible at this time, a deflection or distance for a displacement of the articulated arm 110 to ensure downward. Accordingly, the impact load of the collision body can be effectively absorbed.

Once the lower end P of the rear section 114 of the articulated arm 110 with the inclined wall 136 comes in contact, bends also the articulated arm 110 together with the hinge bracket 120 in the vehicle transverse direction to the outside, wherein the inclined wall 136 serves as a guide. As a result, the impact absorption effect is improved by that the deflection by the buckling of the articulated arm 110 is enlarged. The buckling of the articulated arm 110 to the outside is additionally promoted by the fact that the second connection surface 134 has a high rigidity and is resistant to a load from above.

7 is a view of the hinge bracket 120 out 3 shows. 7 (a) shows a state in which the hinge bracket 120 is considered from a point outside the vehicle, and 7 (b) shows a state in which the hinge bracket 120 from a point inside the vehicle. As in 7 (a) and 7 (b) is shown has the hinge bracket 120 this embodiment flanges 124a and 124b on, which are bent to the inside of the vehicle and a bead 126 coming from a central section of the hinge bracket 120 runs up and in the rear direction of the vehicle.

Because of the hinge mount 120 the flanges 124a and 124b and the bead 126 it is possible to increase the rigidity of the joint mount 120 to increase against a load acting from the top of the vehicle, as disclosed in this embodiment. Accordingly, it is possible to deform the hinge bracket 120 minimize, and the lower end of the articulated arm 110 Can reliably contact the inclined wall 136 come. Because the second interface 134 has a high rigidity against a load acting from the top of the vehicle, buckling the hinge bracket 120 and the articulated arm 110 easier to the outside.

8th is a view that is a reinforcement 170 shows. 8 (a) is a perspective view of the articulated arm 110 and the hinge bracket 120 out 2 , and 8 (b) is a perspective view of the reinforcement 170 , As in 8 (a) shown is the gain 170 with the back of the cowl side panel 130 connected at the position at which the lower end P of the rear-side portion 114 of the articulated arm 110 and the sloping wall 136 of the cowl side panel 130 overlap when viewed from above.

As in 8 (b) is shown has the gain 170 a first contact surface 172 , a second contact surface 176 and a third contact area 178 on. The first contact surface 172 , the second contact surface 176 and the third contact area 178 are each in contact with the backs of the first interface 132 , the inclined wall 136 or the third interface 138 of the cowl side panel 130 , In that the position at which the lower end of the articulated arm 110 with the cowl side panel 130 comes into contact, through the reinforcement 170 reinforced, serves the cowl side panel 130 as a guide, eliminating the articulated arm 110 can buckle sufficiently to the outside.

While the foregoing drawings have exemplified a preferred embodiment of the present invention, it will be understood that the present invention is not limited to the embodiment described above. It will be apparent to those skilled in the art that various modifications and changes can be made within the scope of the invention, which is defined in the appended claims, and these modifications and changes are to be understood to fall within the technical scope of the present invention.
