    FR 3,063,057 - A1
    16 /) Front hood of vehicle (100) comprising an exterior hood panel (102) and an interior hood panel (104) attached to each other; and a reinforcing member (106) arranged between the outer panel (102) and the inner panel (104) and comprising: a main body (114) in the form of a flat plate, having an opening (122, 124) and along the contour the outer panel (102); rear side attachment portions extending into the cantilevered openings from rear edges (128,130) of the openings, and bent towards the inner panel (104) at the rear edges to reach the inner panel (104) and be attached to it; and a front side attachment portion (120) extending forward from a front edge (136) of the main body (114), and bent at the front edge toward the interior panel (104) to reach the interior panel ( 104) and be attached to it.

    (b)
    FRONT COVER OF VEHICLE The present invention relates to a front cover of a vehicle.
    In vehicles such as automobiles, an engine compartment is provided at the front of the vehicle body, and a vehicle front cover which opens and closes is arranged above this engine compartment. In the event of a collision between the vehicle and a collision object (a pedestrian, etc.), the collision object may hit the front hood of the vehicle. This is why the front cover of a vehicle is designed to deform in order to absorb the energy of the collision and to reduce the impact load on the collision object (in particular for a pedestrian).
    In patent document 1, a cover structure is described comprising a cover provided with an exterior panel and an interior panel, and a hood stiffener which is interposed between the exterior panel and the interior panel, and which supports the exterior panel.
    The hood stiffener disclosed in patent document 1 consists of the integration of a main stiffener body, two front legs and three rear legs in one unit. The main stiffener body has a rectangular shape which is elongated across the width of the vehicle and is arranged in a position facing the underside of the exterior panel. The front legs extend forward in the vehicle from the front edge of the main stiffener body, and are attached to the top of the interior panel. The rear legs extend rearward in the vehicle from the rear edge of the stiffener body portion, and are attached to the top of the interior panel.
    Thus, the hood stiffener disclosed in patent document 1 can support the exterior panel from below in the vehicle because the main stiffener body is supported by the front legs and by the rear legs extending from the main body of stiffener towards the inner panel and fixed to the upper face of the inner panel.
    Patent document 1: open Japanese patent N ° 2016-60 395A.
    However, in the cover structure disclosed in patent document 1, no specific measures are taken to reduce the waste of base material when the cover stiffener is cut from the base material. There is therefore room for improvement to reduce the amount of material used to make up the hood stiffener.
    Given the above problems, an object of the present invention provides a vehicle front cover to reduce the amount of material used for a reinforcing member, and reduce the weight and cost.
    To solve the above problems, a vehicle front cover according to one aspect of the present invention having a typical configuration is a vehicle front cover which is arranged at a front portion of a vehicle body, the vehicle front cover comprising: an exterior hood panel and an interior hood panel attached to each other and facing outward and interior respectively of the vehicle; and a reinforcing member which is arranged between the outer cover panel and the inner cover panel. The reinforcing member comprises: a main body having the shape of a flat plate, having an opening and arranged to follow the outline of the outer cover panel; a rear side attachment portion which extends from a rear edge of the opening into the cantilever opening, and which is folded toward the interior hood panel at the rear edge to reach the interior panel hood and be attached thereto; and a front side attachment portion which extends forwardly from a front edge of the main body, and is folded at the front edge toward the interior hood panel to reach and be attached to the interior hood panel .
    The present invention provides a vehicle front cover which is manufactured by reducing the amount of material used for a reinforcing member, the weight and the cost.
    According to other aspects of the invention, the hybrid vehicle can comprise the following characteristics, taken alone or in combination: Front cover of vehicle arranged at a front portion of a vehicle body, the front cover of vehicle comprising: a panel hood exterior and an interior hood panel attached to each other and facing outward and interior respectively of the vehicle; and a reinforcing member which is arranged between the outer hood panel and the inner hood panel, wherein the reinforcing member comprises: a main body having the shape of a flat plate, having an opening and arranged to follow the contour of the hood exterior panel; a rear side fixing portion which extends from a rear edge of the opening into the cantilever opening, and which is folded towards the interior hood panel at the rear edge to reach the interior hood panel and be attached to it; and a front side attachment portion which extends forwardly from a front edge of the main body, and is folded at the front edge toward the interior hood panel to reach and be attached to the interior hood panel .
    In preferred embodiments of the invention, it is possible optionally to have recourse to one and / or the other of the following arrangements:
    an attachment point to which the rear side attachment portion is attached to the interior hood panel is located at the front of an intersection point in the vehicle to which a perpendicular line extending from the rear edge of the opening in a direction perpendicular to the exterior hood panel is intersected with the interior hood panel.
    the rear side fixing portion comprises a small portion and forms a first acute angle of inclination with respect to a reference direction along the main body towards the front of the vehicle, viewed in a vehicle width direction from the main body , the front side fixing portion forms a second acute angle of inclination relative to the reference direction, and the first inclination angle is greater than the second inclination angle, the interior cover panel includes a groove extending in a vehicle width direction, and an attachment point to which the rear side attachment portion is attached to the interior hood panel is adjacent to a vertical wall on a vehicle rear side of the groove.
    attachment points to which the rear side attachment portion is attached to the interior hood panel are weld points aligned in a vehicle width direction.
    The present invention will be described in detail below with reference to the accompanying drawings in which:
    Figure 1 is a diagram schematically showing the external appearance of a vehicle front cover according to an embodiment of the present invention;
    Figure 2 is a diagram showing an enlargement of a portion of the vehicle front hood shown in Figure 1;
    Figure 3 is a cross-sectional diagram of the front hood of the vehicle along the line A-A of Figure 2;
    Figure 4 is a diagram of a reinforcing member shown in Figure 3, in oblique view from above;
    Figure 5 is a diagram showing the behavior of the reinforcement member of Figure 3 in a collision;
    Figure 6 is a diagram schematically showing the reinforcing member of Figure 2 and a reinforcing member of a comparative example.
    A vehicle front cover according to one aspect of the present invention, having a typical configuration, is a vehicle front cover which is arranged at a front portion of a vehicle body, the vehicle front cover comprising: a panel hood exterior and an interior hood panel attached to each other and facing outward and interior respectively of the vehicle; and a reinforcing member which is arranged between the outer cover panel and the inner cover panel. The reinforcing member comprises: a main body having the shape of a flat plate, having an opening and arranged to follow the outline of the outer cover panel; a rear side attachment portion which extends from a rear edge of the opening into the cantilever opening, and which is folded toward the interior hood panel at the rear edge to reach the interior panel hood and be attached thereto; and a front side attachment portion which extends forwardly from a front edge of the main body, and is folded at the front edge toward the interior hood panel to reach and be attached to the interior hood panel .
    In the configuration described above, the front side fixing portion can be fixed to the interior cover panel because it is folded at the front edge of the main body. The rear side mounting portion can be attached to the interior hood panel because it is folded at the rear edge of the opening. Therefore, the reinforcing member can be fixed to the outer cover panel via the main body, and it can be fixed to the inner cover panel via the front side fixing portion and the portion rear side fixing. In addition, before being folded, the rear side attachment portion extends into the overhanging main body opening, and is thus enclosed by the main body. When cutting the main body, the front side fixing portion and the rear side fixing portion from the base material, it is therefore not necessary to prepare a region for the rear side fixing portion separately, provided the base material is large enough to cover the main body and the front side attachment portion. In the configuration described above, the size of the base material can therefore be reduced and the amount of material used, the weight and the cost can also be reduced.
    It is preferable that a fixing point to which the rear side fixing portion is fixed to the interior hood panel is located at the front of a point of intersection in the vehicle to which a perpendicular line extending from the rear edge of the opening in a direction perpendicular to the exterior hood panel is intersected with the interior hood panel. Relative to the direction perpendicular to the hood exterior panel, i.e. the load entry direction, the fixing point at which the rear side fixing portion is fixed to the hood interior panel is at the in front of the rear edge of the main body opening, i.e. in front of the upper end of the rear side fixing portion in the vehicle. When the reinforcing member is subjected to a load during a collision between the front hood of the vehicle and a pedestrian, the rear side fixing portion in the reinforcing member deforms and is crushed in the vertical direction of the vehicle under the effect of the load acting in the vertical direction of the vehicle, and it also deforms reliably under the effect of the moment generated moving it backwards in the vehicle. The rear side attachment portion in the reinforcing member therefore undergoes rearward bending and the like in the vehicle under the effect of the load in a collision. The impact can therefore be easily absorbed and the injury sustained by the pedestrian during the collision can be reduced. Likewise, the rear side attachment portion is formed in the vertical direction of the vehicle. It is therefore likely that the rear side attachment portion bends under the effect of a collision load acting in the vertical direction of the vehicle.
    It is preferable that the rear side fixing portion comprises a small portion and forms a first acute angle of inclination relative to a reference direction along the main body towards the front of the vehicle, viewed in one direction. vehicle width of the main body, that the front side fixing portion forms a second acute angle of inclination with respect to the reference direction, and that the first inclination angle is greater than the second inclination angle. In this way, in the reinforcing member, the angle of inclination of the rear side fixing portion relative to the reference direction of the main body is greater than that of the front side fixing portion. Consequently, the load in a collision is reliably transmitted to the rear side attachment portion in the reinforcing member. The rear side attachment portion includes the weak portion facilitating deformation. It is thus certain that the weak portion deforms during a collision. Consequently, in a collision, the reinforcing member deforms downwards in the vehicle and approaches the interior bonnet panel, which allows the reinforcing member to absorb the energy of the impact and ensure the ability to protect the pedestrian.
    It is preferable that the interior cover panel includes a groove extending in a vehicle width direction, and that an attachment point to which the rear side attachment portion is attached to the interior cover panel is adjacent to a vertical wall on a rear side of the vehicle from the groove. In this way, the rear side fixing portion of the reinforcing member is fixed adjacent to the portion of the interior cover panel with increased rigidity, that is to say adjacent to the vertical wall formed by the groove. The rigidity of the attachment between the reinforcing member and the inner cover panel can thus be increased. Therefore, in the configuration described above, when a comparatively small load is entered, the interior hood panel as a whole can reduce deformation of the reinforcing member and can suppress deformation of the exterior hood panel and, when a comparatively large load has entered, the reinforcement member deforms reliably and is able to absorb the energy of the impact.
    It is preferable that the fixing points to which the rear side fixing portion is fixed to the interior hood panel are welding points aligned in a vehicle width direction. Here, the front cover of the vehicle tends to deform in the front-rear direction of the vehicle under the effect for example of a load undergone by the repetition of the opening and closing of the latter. In the configuration described above, by aligning the welding points, which are the fixing points to which the rear side fixing portion is fixed to the interior hood panel, in the vehicle width direction, the welding points are arranged orthogonally to the front-rear direction of the vehicle, which is the direction of deformation of the front hood of the vehicle. By arranging the welds in this way, the load on opening and closing the front hood of the vehicle can be dispersed for the most part uniformly, the weld is unlikely to come off and the fixing force can be maintained.
    Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials and other specific numerical values described in these embodiments are purely exemplary and are intended to facilitate understanding of the present invention. They are not intended to be construed as limiting the invention, unless otherwise indicated. It should be noted that elements constituting substantially identical functions and configurations bear identical reference numbers in this specification and in the accompanying drawings, and their redundant description is therefore omitted. Likewise, illustrations of elements which are not directly relevant in the context of the present invention have been omitted.
    Figure 1 is a diagram schematically showing the external appearance of a vehicle front cover 100 according to an embodiment of the present invention. Figure 2 is a diagram showing an enlargement of a portion of the front cover of vehicle 100 shown in Figure 1. Figure 2 (a) is a perspective view of the front cover of vehicle 100, in oblique view from above. Figure 2 (b) is a diagram of the front cover of vehicle 100, viewed from above.
    The vehicle front cover 100 is arranged above an engine compartment not shown at the front of the vehicle body. The front cover of the vehicle 100 comprises an external cover panel 102 constituting the external face of the latter, an internal cover panel 104, and a reinforcing member 106 shown in FIG. 2. Note that the external cover panel 102 is not shown in Figure 2.
    The interior cover panel 104 is a member constituting the interior face of the front cover of the vehicle 100, and is arranged below the exterior cover panel 102. The interior cover panel 104 has a groove 108 which extends in the vehicle width direction. The groove 108 has a lower portion 110, and a vertical wall 112 on the rear side of the vehicle of the lower portion 110, the vertical wall 112 having a height difference in the front-rear direction of the vehicle. The groove 108 is a portion of the inner cover panel 104 where the rigidity is increased.
    The reinforcing member 106 is a member which is arranged between the outer cover panel 102 and the inner cover panel 104. It is cut from a basic material of a predetermined size (cf. FIG. 6 (a )). The role of the reinforcing member 106 is to maintain the shape of the exterior hood panel 102 by ensuring surface rigidity against a load occurring during the opening or closing of the front hood of the vehicle 100, and by ensuring the capacity to protect a pedestrian during a collision by deformation and absorption of the impact.
    The reinforcing member 106 comprises a main body 114, two rear side fixing portions 116 and 118, and a front side fixing portion 120. The main body 114 has the form of a flat plate, it has two openings 122 and 124 and it is arranged to follow the contour of the outer cover panel 102. The two openings 122 and 124 are partitioned by a bridging portion 126 which extends in the front-rear direction of the vehicle. They are aligned in the vehicle width direction. Sealant is applied, for example, to a plurality of predetermined portions of the upper face of the main body 14 and the upper face adheres to the lower face of the outer cover panel 102.
    As shown by the dashed line in Figure 2 (a), before being folded, the rear side fastening portions 116 and 118 extend respectively overhanging from rear edges 128 and 130 of the openings 122 and 124 in the openings 122 and 124, and they are enclosed by the main body 114. Similarly, as shown with the arrows in Figure 2 (a), the rear side fixing portions 116 and 118 reach the interior cover panel 104 by being folded towards the interior cover panel 104, at the rear edges 128 and 130. Then, the rear side fixing portions 116 and 118 are fixed to the interior cover panel 104 at attachment points 132a, 132b, 134a and 134b, as shown in Figure 2 (b).
    The fixing points 132a, 132b, 134a and 134b between the rear side fixing portions 116 and 118 and the interior cover panel 104 are adjacent to the vertical wall 112 of the groove 108 of the interior cover panel 104. In the reinforcing member 106, the rear side fixing portions 116 and 118 are fixing portions of the inner cover panel 104 to which the rigidity is high. The rigidity of the attachment between the inner cover panel 104 and the reinforcing member 106 can therefore be increased.
    Therefore, when a comparatively small load acts on the front cover of vehicle 100 during operations such as opening or closing the cover, the interior cover panel 104 as a whole can reduce deformation of the reinforcing member 106, and can suppress a deformation of the outer cover panel 102. Furthermore, when a comparatively large load acts on the front cover of the vehicle 100 during a collision with a pedestrian or a similar collision , the reinforcing member 106 deforms reliably and can absorb the energy of the impact.
    Here, the vehicle front cover 100 tends to deform in the front-rear direction of the vehicle under the effect of the load undergone by the repetition of operations such as opening and closing the cover. The fixing points 132a, 132b, 134a and 134b are aligned in a straight line in the vehicle width direction, as shown in FIG. 2 (b), and they are orthogonal to the direction of deformation of the vehicle front cover 100 By arranging the fixing points 132a, 132b, 134a and 134b in this way, the load undergone by the opening and closing can be dispersed for the most part uniformly in the front hood of the vehicle 100. Consequently, there is little the weld is likely to come off and the fixing force can be maintained.
    The front side fixing portion 120 extends from a front edge 136 of the main body 114. It is folded towards the interior cover panel 104 at the front edge 136 to reach the interior cover panel 104 and be fixed to this one. The reinforcing member 106 is therefore fixed to the outer cover panel 102 via the main body 114, and it is fixed to the inner cover panel 104 via the front side fixing portion 120 and portions rear side mounting 116 and 118.
    Figure 3 is a cross section of the front cover of the vehicle 100 along the line AA in Figure 2. Note that the outer cover panel 102 is shown with a chain line in Figure 3. The line perpendicular B is a line extending in the direction perpendicular to the outer cover panel 102, that is to say in the direction of load entry from the rear edge 128 of the opening
    122, and it intersects the interior cover panel 104 at the point of intersection C. Among the rear side fixing portions 116 and 118, only the rear side fixing portion 116 will be described below. The configuration, functions, and the like, of the rear side attachment portion 118 are identical to those of the rear side attachment portion 116.
    The fixing point 132a to which the rear side fixing portion 116 is fixed to the interior cover panel 104 is located at the front of the point of intersection C in the vehicle, as shown in FIG. 3. The attachment point 132a of the rear side attachment portion 116 is located at the front, with respect to the load entry direction, of an upper end 137 of the rear side attachment portion 116 in the vehicle. When the reinforcing member 106 in the front hood of the vehicle 100 receives a load during a collision with a pedestrian or another collision, the reinforcing member 106 is liable to be subjected to a moment moving it towards the rear in the vehicle.
    As shown in Figure 3 describing the main body 114 in view in the vehicle width direction, the rear side fixing portion 116 forms a first acute angle of inclination Oa relative to the reference direction D along the main body 114 facing towards the front of the vehicle. Likewise, the front side fixing portion 120 forms a second acute angle of inclination Ob with respect to the reference direction D. The first inclination angle Oa is larger than the second inclination angle Ob. Since the rear side fixing portion 116 in the reinforcing member 106 forms a tilt angle which is larger than the tilt angle formed by the front side fixing portion 120, relative to the reference direction D of the main body 114, the impact load is reliably transmitted to the rear side fixing portion 116.
    As shown in Figure 3, the rear side attachment portion 116 is attached to the hood interior panel 104 on the vehicle rear side of the groove 108. The front side attachment portion 120 is attached to the hood interior panel 104 on the vehicle front side of the groove 108. The reinforcing member 106 overlaps portions of the hood interior panel
    104 where the rigidity is increased, in the front-rear direction of the vehicle, and it is fixed to the interior hood panel 104 by means of the front side fixing portion 120 and the rear side fixing portions 116 and 118. The rigidity of attachment between the reinforcing member 106 and the inner cover panel 104 can therefore be increased.
    The front cover of vehicle 100 further comprises a keeper 138 and a keeper reinforcement member 140 which are attached to the underside of the inner cover panel 104, as shown in Figures 3 and 5. The striker reinforcement member 140 is a member for reinforcing the portion to which the striker 138 is attached to the underside of the interior hood panel 104, and ensures the strength of the vehicle front hood 100 when it is opened and closed.
    The keeper reinforcing member 140 is attached to the front side fixing portion 120 and the interior cover panel 104 is interposed therebetween. A load undergone by the front side fixing portion 120 is thus also transmitted to the keeper reinforcement member 140 which disperses it, by means of the interior cover panel 104. The rigidity of the attachment between the member reinforcement 106 and the inner cover panel 104 can thus be further increased. In addition, joined portions can be reduced by the use of attachments, which can lead to cost reduction.
    Figure 4 is a diagram showing the reinforcing member 106 shown in Figure 3, in oblique view from above. The rear side fixing portion 116 of the reinforcing member 106 extends from the rear edge 128 of the opening 122 and reaches the interior cover panel 104 to which it is fixed, as shown in FIG. 4 ( at). The rear side attachment portion 116 has a weak portion 142, as shown enlarged in Figure 4 (b).
    The weak portion 142 is a portion which is folded into a protruding shape on the front side of the vehicle and it extends in the width direction of the vehicle, as shown in Figure 4 (b). The rear side fixing portion 116 comprises a folded portion 144. The folded portion 144 is located higher in the vehicle than the weak portion 142. It is provided near the rear edge 128 of the opening 122, that is ie at the upper end 137. A bead portion 146 which extends in the vertical direction of the vehicle is formed in the center of the folded portion 144 in the direction of the width of the vehicle.
    In this way, in the rear side fixing portion 116, the folded portion 144 which includes the bead portion 146 formed at a higher position than the weak portion 142 in the vehicle ensures the rigidity of the upper end 137, and a deformation during a collision is facilitated by the weak portion 142.
    Figure 5 is a diagram showing the behavior of the reinforcing member 106 shown in Figure 3 in a collision. Figure 5 (a) shows the state of the reinforcing member 106 before a collision. Figure 5 (b) shows a reinforcing member 106 deformed after a collision.
    In the reinforcement member 106, the fixing point 132a of the rear side fixing portion 116 is located at the front of the point of intersection C in the vehicle, as shown in FIG. 3. The angle of inclination of the rear side fixing portion 116 relative to the reference direction D of the main body 114 is greater than that of the front side fixing portion 120. The rear side fixing portion 116 comprises the weak portion 142, as shown in FIG. 4 (b).
    In the reinforcing member 106, as shown in FIG. 5 (b), the load during a collision is reliably transmitted to the rear side fixing portion 116, which deforms towards the low in the vehicle under the effect of the load, a moment towards the rear of the vehicle is generated, and the weak portion 142 deforms reliably under the effect of the load. Consequently, when the reinforcing member 106 is subjected to a load during a collision, the rear side fixing portion 116 deforms and folds backwards in the vehicle, starting at the weak portion 142, and approaches the hood interior panel 104, as shown in Figure 5 (b). The reinforcing member 106 can mitigate the injury sustained by a pedestrian during the collision by absorbing the energy of the collision impact, and can provide the ability to protect the pedestrian.
    Figure 6 is a diagram schematically showing the reinforcing member 106 of Figure 2 and a reinforcing member 200 of a comparative example. The chain lines E and L in FIG. 6 (a) and in FIG. 6 (b) indicate the basic material necessary to cut the reinforcement members 106 and 200 respectively.
    As shown in Figure 6 (a), the rear side attachment portions 116 and 118 of the reinforcing member 106 are enclosed by the main body 114 because the rear side attachment portions are not folded 116 and 118 extend in overhang in the openings 122 and 124 of the main body 114. This is why, during the formation of the main body 114, the front side fixing portion 120, and portions rear side attachment 116 and 118 in the base material, there is no need to separately prepare a region for the rear side attachment portions 116 and 118 which are enclosed by the main body 114. In other words , it suffices that the base material is large enough to cover the main body 114 and the front side fixing portion 120. Here, the size of the base material is indicated by the dimension La in the front direction of the vehicle and the dimension Lb across the vehicle width cule, as shown in Figure 6 (a).
    As shown in Figure 6 (b), the reinforcing member 200 of the comparative example is different from the reinforcing member 106 of this embodiment in that the rear side fixing portions unfolded 202 and 204 extend in the rearward direction of the vehicle from rear edges 128 and 130 of a main body 206, and are outside the body portion 206.
    In the comparative example, when the reinforcing member 200 is formed in the base material, the base material must be large enough to cover the body portion 206 and the front side fixing portion 120 and it It is also necessary to separately prepare a region for the rear side fixing portions 202 and 204 which are outside the body portion 206.
    Therefore, with regard to the dimensions in the direction of vehicle width, the size of the base material in the comparative example, as shown in Figure 6 (b), has the same dimension Lb as in the size of the base material of the reinforcing member 106, but the dimension Le in the front-rear direction of the vehicle is different. The dimension Le is a dimension obtained by adding the dimension Ld in the front-rear direction of the vehicle of the rear side fixing portions 202 and 204 in the reinforcement member 200 to the dimension La in the front-rear direction of the vehicle of the reinforcing member 106 of this embodiment. In other words, in the comparative example, when the reinforcing member 200 is cut from the base material, it is necessary to separately prepare a region for the rear side fixing portions 202 and 204 which are at the outside of the body portion 206, which causes an increase in the size of the base material.
    Contrary to the above, in the present embodiment, when the reinforcing member 106 is cut from the base material, it is not necessary to prepare a region separately for the rear side fixing portions 116 and 118 which are enclosed by the main body 114. Therefore, the size of the base material can be reduced, the amount of material used can be reduced, and the weight and cost can also be reduced.
    In the embodiment described above, the main body 114 has two openings 122 and 124 which are partitioned by the bridging portion 126, but the embodiment is not limited to this. In one example, the main body 114 may also have a single opening in which there is no bridging portion 126. As a variant, three or more openings may be formed by a plurality of bridging portions 126. Likewise, the rear side attachment portions 116 and 118 are not limited to two. Their number can be equal to one or greater than or equal to three, provided that they are at the rear edge of an opening and are enclosed by the main body 114 before being folded. Even in this case, when the reinforcing member is cut from the base material, it is not necessary to separately prepare a region for a rear side fixing portion which is enclosed by the main body 114. Therefore, the size of the base material can be reduced.
    Although a preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it should be understood that the present invention is not limited to the embodiment described above. Those skilled in the art can appreciate that various modifications and variations can be made within the scope of the invention, as defined in the appended claims. Such modifications and variations are intended to be included within the technical scope of the present invention.
    The present invention can be used as the front cover of the vehicle.
