Description

  The present invention relates to an instrument panel that is disposed in a front portion of a vehicle and partitions an engine room and a passenger compartment space.

  In the front part of the vehicle, an engine room and a compartment space are partitioned by an instrument panel. In recent years, as the number of vehicle-mounted devices (assembled parts) that are assembled into or housed in an instrument panel increases, the width in the vehicle front-rear direction of the top surface (upper surface) of the instrument panel tends to increase. is there. As a result, when the occupant comes into contact with the top surface of the instrument panel or puts an object on the top surface, a so-called stickiness is likely to occur.

  As a method for suppressing the stickiness, the top surface and the vertical surface (standing wall) of the instrument panel are connected by a reinforcing bracket made of sheet metal, or the instrument panel and a steering support member disposed in front of the instrument panel are connected to the sheet metal. It has been conventionally performed to connect with a reinforcing bracket. For example, in Patent Document 1, the upper wall of the instrument panel is supported by a support member erected from a steering support member.

JP 2008-168753 A

  However, the conventional method of providing a reinforcing bracket and a support member causes an increase in weight and cost due to an increase in the number of parts. Moreover, since the operation | work for attaching a reinforcement bracket to an instrument panel or another member is needed, the number of processes will also increase. For this reason, development of the structure which can reinforce the top | upper surface of an instrument panel, without adding the component for reinforcement was desired.

  The present invention has been made in view of such problems, and an object thereof is to provide an instrument panel that can reinforce the top surface with a simple structure and can reduce the cost, weight, and the like associated with the reinforcing component. It is said.

  In order to solve the above-described problems, a representative configuration of an instrument panel according to the present invention is an instrument panel that is disposed in a front portion of a vehicle and partitions an engine room and a vehicle compartment space, and the top surface of the instrument panel. Is located on the front side of the vehicle in the vicinity of the boundary between the top surface and the vertical surface portion, and has a quadrilateral side wall, a front wall, and a bottom surface. A three-dimensional rib in which the wall is three-dimensionally combined, and among the four sides of the side wall, the upper side is continuous with the top surface portion, the side on the vehicle rear side is continuous with the vertical surface portion, and among the four sides of the front wall The upper side is continuous with the top surface portion, and either side is continuous with the side of the side wall on the vehicle front side, and among the four sides of the lower wall, three sides are the vertical surface portion, the lower side of the side wall, and the front wall. It is characterized by being continuous with the lower side.

  In the instrument panel, the three-surface rib provided on the vehicle front side (rear side) in the vicinity of the boundary between the top surface portion and the vertical surface portion includes a side wall, a front wall, and a lower wall. A box shape in which one surface other than these is opened is formed. Of the three-surface ribs, the side wall that is continuous with the top surface portion and the vertical surface portion functions as a tension bar between them, and supports the top surface portion. Thereby, the rigidity of a top surface part can be improved, the deformation | transformation when a load is applied to a top surface part by a passenger | crew's contact or mounting | wearing of an article | item can be suppressed, and malfunctions, such as stickiness, can be prevented. Further, since the front wall and the lower wall are continuous with the side wall, the rigidity of the side wall can be improved. Furthermore, when the side wall and the front wall are continuous, the top surface portion can be reinforced by the surface, and when the side wall and the lower wall are continuous, the vertical surface portion can be reinforced by the surface. This makes it possible to increase the rigidity in the vicinity of the boundary portion of the instrument panel.

  Therefore, according to the above configuration, the instrument panel is reinforced by the three-surface rib integrally provided with the instrument panel on the vehicle front side in the vicinity of the boundary between the top surface portion and the vertical surface portion to prevent deformation such as stickiness. It becomes possible. In this way, the top surface of the instrument panel can be reinforced with a simple structure without separately providing a reinforcing component, thereby reducing the cost and weight associated with the reinforcing component, and reinforcing the conventional method. It is also possible to reduce the process required for mounting the parts for the machine.

  The instrument panel may further include a fixing portion to which the design component is fixed on the vehicle rear side, and the three-surface ribs may be provided in the vicinity of the fixing portion. By arranging the three-surface ribs in the vicinity of the fixed part in this manner, the rigidity of the vicinity of the fixed part in the instrument panel, that is, the location serving as the mounting base is increased. Thereby, bending (deformation) in the vicinity of the fixed portion at the time of attaching the design component can be suppressed, and workability (assembly) at the time of attachment can be improved.

  The instrument panel further includes an opening in which an assembly part to be assembled to the instrument panel can be arranged, and the three-surface rib is preferably provided in the vicinity of the end of the opening. Thus, by arranging the three-surface rib in the vicinity of the end of the opening, the rigidity in the vicinity thereof can be increased. Thereby, it becomes possible to prevent the deformation | transformation of the edge part of the opening part by the load applied at the time of transportation of the instrument panel after shaping | molding, or conveyance.

  The top surface portion of the instrument panel has two or more curvature change portions where the curvature changes, and the three-surface rib is provided between two adjacent curvature change portions among the two or more curvature change portions. It is good to have. In general, a portion where the curvature changes (curvature changing portion) has high rigidity. On the other hand, between two adjacent curvature change portions, that is, a region where there is no change in curvature (hereinafter referred to as a plane portion), the rigidity is lower than that of the curvature change portion, and stickiness when a load is applied occurs. Cheap. Therefore, by arranging the three-surface rib in the plane portion between the two curvature change portions as in the above configuration, the plane portion can be effectively reinforced, and the stickiness that easily occurs is suitably prevented. It becomes possible.

  In the side wall, the sum of the length of the upper side and the length of the side on the vehicle rear side may not match the sum of the length of the lower side and the length of the side of the vehicle front side. Of the four sides of the side wall, the length of the upper side is the same as the length from the continuous portion of the top surface to the front wall to the boundary, and the length of the side on the vehicle rear side is the lower wall of the vertical surface. The length of the lower side is the same as the length from the front end to the rear end of the lower wall, and the length of the side side on the vehicle front side is the length of the front wall. It is the same as the length from the upper end to the lower end. For this reason, the above configuration is “in the longitudinal sectional view in the vehicle front-rear direction, the length from the continuous portion with the front wall in the top surface portion to the boundary portion, and from the continuous portion with the lower wall in the vertical surface portion to the boundary portion. In other words, the sum from the front end to the rear end of the lower wall does not match the sum from the upper end to the lower end of the front wall. "

  According to the above configuration, in the longitudinal sectional view in the vehicle front-rear direction, the quadrangle formed by the front wall and the lower wall, the top surface portion, and the vertical surface portion is not a parallelogram. In other words, the boundary between the front wall and the lower wall is located on a line segment passing through the boundary between the top surface and the vertical surface and the midpoint of the line segment connecting the upper end of the front wall and the rear end of the lower wall. do not do. In this way, by placing the boundary between the front wall and the lower wall at a position that is not diagonal to the boundary between the top surface and the vertical surface, the instrument panel can be folded starting from the boundary between the top and vertical surfaces. Can be prevented. Thereby, the box shape which consists of a 3 surface rib, a top | upper surface part, and a vertical surface part can be hold | maintained suitably, and it becomes possible to further raise the reinforcement effect.

  The side wall may have a longer upper side than a side side on the vehicle rear side. According to this configuration, the side wall is continuous with the top surface portion longer than the vertical surface portion. Thereby, it becomes possible to reinforce the base of the top surface portion in a longer range in the vehicle front-rear direction at the boundary portion of the instrument panel. Therefore, it is possible to suitably prevent drooping starting from a boundary portion that is likely to occur in an instrument panel whose top surface portion is long in the longitudinal direction of the vehicle.

  An extension rib may be formed on the lower side of the top surface portion so as to extend from the front wall of the front wall toward the front of the vehicle. Thereby, the instrument panel can be reinforced in a longer range in the vehicle front-rear direction. Further, since the front wall and the extension rib are continuous, the rigidity of the front wall and thus the three-surface rib can be improved, and the reinforcement effect of the instrument panel by the three-surface rib can be further enhanced.

  A through hole may be formed in at least one of the side wall, the front wall, and the lower wall. Thereby, it becomes possible to utilize a through-hole as a clamp hole of harnesses routed inside an instrument panel, such as an electric wire connected to an assembly part assembled in an instrument panel.

  According to the present invention, it is possible to provide an instrument panel that can reinforce the top surface with a simple structure and can reduce costs, weight, and the like associated with the reinforcing component.

It is a back perspective view of the state where design parts were attached to the instrument panel of 3 (a). In order to facilitate understanding, the design component 140 is illustrated by hatching in FIGS. 2 and 3B.

  An instrument panel (hereinafter referred to as an instrument panel 100) shown in FIG. 1 is an interior member that is disposed in the front portion of the vehicle and partitions an engine room and a vehicle compartment space (not shown). The instrument panel 100 has a top surface constituted by a top surface portion 110 extending in the vehicle front-rear direction, and a vertical surface portion 120 extends downward from an end portion of the top surface portion 110 on the vehicle rear side. Hereinafter, the boundary between the top surface portion 110 and the vertical surface portion 120 is referred to as a boundary portion 130.

  The instrument panel 100 is assembled with assembly parts (not shown) such as car navigation, audio, and instruments. In order to make it possible to arrange this assembled part on the instrument panel 100, openings are formed in the top surface portion 110 and the vertical surface portion 120. As this opening, FIG. 1 illustrates an opening 122 in which car navigation is arranged.

  As shown in FIG. 2, the design component 140 is attached to the instrument panel 100 on the vehicle rear side (front side). As shown in FIG. 3A, the vertical surface portion 120 of the instrument panel 100 is provided with mounting holes 124a and 124b as fixing portions to which the design component 140 (see FIG. 2) is fixed. As shown in FIG. 3B, the design is performed by fitting the mounting portions 142 a and 142 b provided on the back side of the design component 140 into the mounting holes 124 a and 124 b (see FIG. 3A) of the vertical surface portion 120. The component 140 is fixed to the instrument panel 100. Note that the mounting holes 124a and 124b, which are the fixing portions of the present embodiment, and the mounting portions 142a and 142b fitted therein are merely examples, and other fixing methods are not excluded.

  As a feature of the present embodiment, a three-sided rib 150 is formed on the vehicle front side (back side) in the vicinity of the boundary portion 130 (the boundary between the top surface portion 110 and the vertical surface portion) of the instrument panel 100. As shown in FIG. 3, the trihedral rib 150 is configured by three-dimensionally combining three walls (ribs) of a quadrilateral side wall 152, a front wall 154, and a lower wall 156.

  FIG. 4 is a diagram for explaining the three-surface rib 150, and is an exploded view of the three-surface rib 150 shown in FIG. As shown in FIG. 4, the side wall 152 has an upper side 152a, a lower side 152b, and two side sides 152c and 152d. Of these four sides, the upper side 152a is continuous with the top surface portion 110, and the rear side of the vehicle. The side edge 152d is continuous with the vertical surface portion 120. The side wall 152 functions as a tension rod between the top surface portion 110 and the vertical surface portion 120, and supports the top surface portion 110 to improve its rigidity. Thereby, the deformation | transformation of the top | upper surface part 110 when a load is applied by a passenger | crew's contact or mounting | wearing of an article | item can be suppressed, and malfunctions, such as a stickiness, can be prevented.

  The front wall 154 has an upper side 154a, a lower side 154b, and two side sides 154c and 154d, and among these four sides, the upper side 154a is continuous with the top surface part 110, and either one side (this embodiment) , The side 154 c) is continuous with the side 152 c on the vehicle front side of the side wall 152. Three sides of the lower wall 156 are continuous with the vertical surface portion 120, the lower side 152b of the side wall 152, and the lower side 154b of the front wall 154, respectively. Specifically, the lower wall 156 has a front side 156a, a rear side 156b, and two side sides 156c and 156d, and among these four sides, the front side 156a is continuous with the lower side 154b of the front wall 154. The rear side 156b is continuous with the vertical surface portion 120, and any one side (the side 156c in this embodiment) is continuous with the lower side 152b of the side wall 152.

  Since the front wall 154 and the lower wall 156 are continuous with the side wall 152 as described above, the rigidity of the side wall 152 can be improved. Further, the top surface portion 110 is reinforced by the surface by the side wall 152 and the front wall 154 being continuous, and the vertical surface portion 120 is reinforced by the surface by the side wall 152 and the lower wall 156 being continuous. As a result, the rigidity of the instrument panel 100 near the boundary 130 can be further increased.

  That is, on the vehicle front side (rear side) in the vicinity of the boundary portion 130 of the instrument panel 100 of the present embodiment, a box shape in which one surface other than those is opened by the three-surface rib 150, the top surface portion 110, and the vertical surface portion 120 is formed. It is formed. Thereby, it is possible to obtain a much higher reinforcing effect than when the ribs are simply provided on the back surface of the instrument panel 100, and it is possible to more effectively suppress problems such as stickiness. Further, the three-surface rib 150 is formed integrally with the instrument panel 100, unlike a component (reinforcing component) conventionally required for reinforcing the top surface portion. In this way, the top panel 110 of the instrument panel 100 can be reinforced with a simple structure without the need for reinforcing parts, so that it is necessary to reduce the cost and weight of the reinforcing parts and to attach the reinforcing parts. It is possible to reduce the number of processes.

  Further, according to the above-described three-surface rib 150, each of the side wall 152, the front wall 154, and the lower wall 156 reinforces another continuous wall (rib), so that the rigidity of each wall (rib) is improved. Is done. For this reason, as shown in FIG. 3, it is possible to form a through hole 158 in the rib (in this embodiment, the side wall 152 is exemplified). Accordingly, harnesses (not shown) routed inside the instrument panel 100 such as electric wires connected to assembly parts (not shown) to be assembled to the instrument panel 100 can be inserted, and the through holes 158 can be used as clamp holes. It is.

  In the present embodiment, the through hole 158 is formed in the side wall 152, but the present invention is not limited to this, and the through hole 158 may be formed in the front wall 154 or the lower wall 156. Further, the number of the through holes 158 is merely an example, and the through holes 158 may be provided in two or more ribs of the side wall 152, the front wall 154, and the lower wall 156, or two or more through holes 158 may be provided in one rib. It is also possible to form

  FIG. 5 is a cross-sectional view taken along line AA in FIG. Hereinafter, as shown in FIG. 5, in a longitudinal sectional view in the vehicle front-rear direction, the length from the continuous portion with the front wall 154 of the top surface portion 110 to the boundary portion 130 is L1, and the lower wall 156 of the vertical surface portion 120 is The length from the continuous portion to the boundary portion 130 will be referred to as L2, the length from the upper end to the lower end of the front wall 154 will be referred to as L3, and the length from the front end to the rear end of the lower wall 156 will be referred to as L4.

  As shown in FIG. 5, in the three-surface rib 150, the sum (L3 + L4) of the length (L3) from the upper end to the lower end of the front wall 154 and the length (L4) from the front end to the rear end of the lower wall 156 The sum of the length (L1) from the continuous portion with the front wall 154 to the boundary portion 130 in the top surface portion 110 and the length (L2) from the continuous portion with the lower wall 156 to the boundary portion 130 in the vertical surface portion 120 ( L1 + L2) does not match (L1 + L2 ≠ L3 + L4). In other words, in the longitudinal sectional view in the longitudinal direction of the vehicle, the side wall 152 is obtained by adding the length of the upper side 152a to the length of the side 152d on the vehicle rear side and the length of the lower side 152b on the vehicle front side. The sum obtained by adding the lengths of the side edges 152c does not match (see FIG. 4).

  If “L1 + L2 = L3 + L4”, the front and lower walls (shown by broken lines in FIG. 5), and the top surface portion 110 and the vertical surface portion 120 in the longitudinal sectional view in the vehicle front-rear direction. Becomes a parallelogram. Then, the boundary portion (point P1) between the front wall and the lower wall illustrated by a broken line is the midpoint P2 of the line segment B connecting the upper end of the front wall 154 and the rear end of the lower wall 156, the top surface portion 110, and the vertical surface portion. 120, the boundary portion of the front wall and the lower wall (point P1) and the boundary portion 130 of the top surface portion 110 and the vertical surface portion 120 are diagonally located. Will be located. In such a case, when a large load is applied to the top surface portion 110 near the boundary portion 130 in the instrument panel 100, the instrument panel 100 may be bent starting from the boundary portion 130.

  On the other hand, in the present embodiment, “L1 + L2> L3 + L4” is satisfied and the above-described condition “L1 + L2 ≠ L3 + L4” is satisfied. In such a case, as shown in FIG. 5, the quadrangle formed by the front wall 154 and the lower wall 156, and the top surface portion 110 and the vertical surface portion 120 is not a parallelogram in a longitudinal sectional view in the vehicle longitudinal direction. . Therefore, it is possible to avoid the boundary portion 155 between the front wall 154 and the lower wall 156 and the boundary portion 130 between the top surface portion 110 and the vertical surface portion 120 being positioned diagonally. As a result, the instrument panel 100 can be prevented from being bent starting from the boundary portion 130 between the top surface portion 110 and the vertical surface portion 120, and the box shape composed of the three-surface rib 150 and the top surface portion 110 and the vertical surface portion 120 is preferably maintained. Thus, a high reinforcing effect can be obtained.

  More preferably, in the longitudinal sectional view in the vehicle front-rear direction, the side wall 152 has a longer upper side 152a than a side side 152d on the vehicle rear side (see FIG. 4). The length of the side 152d on the vehicle rear side of the side wall 152 is the same as the length (L2) from the continuous portion of the vertical surface 120 to the lower wall 156 to the boundary 130, and the length of the upper side 152a of the side wall 152. Is the same as the length (L1) from the continuous portion of the top surface portion 110 with the front wall 154 to the boundary portion 130, and in other words, “L1> L2”.

  According to the above configuration, the side wall 152 is continuous with the top surface portion 110 longer than the vertical surface portion 120 and is a wall (rib) that is long in the vehicle front-rear direction. Thereby, the base of the top surface part 110 of the instrument panel 100 can be reinforced in a longer range in the vehicle front-rear direction. Therefore, it is possible to suitably prevent the top surface portion 110 from drooping starting from the boundary portion 130 that is likely to occur in the instrument panel 100 that is long in the longitudinal direction of the vehicle, that is, the tip of the instrument panel 100 on the vehicle rear side.

  In order to further enhance the reinforcing effect of the top surface portion 110 of the instrument panel 100 in the vehicle front-rear direction, in the present embodiment, further from the surface of the front wall 154 on the vehicle front side to the lower side (rear side). An extension rib 160 extending toward the front of the vehicle is provided. Thereby, the instrument panel 100 can be reinforced in a longer range in the vehicle longitudinal direction. Further, since the extension rib 160 is continuous with the front wall 154, the rigidity of the front wall 154 and thus the three-surface rib 150 can be improved, and the reinforcing effect of the instrument panel 100 by the three-surface rib 150 can be further enhanced. Become.

  Here, as described above, the design component 140 is attached to the rear side (front side) of the instrument panel 100 (see FIG. 2). When the design component 140 is pressed against the vertical surface portion 120 in order to fit the mounting portions 142a and 142b into the mounting holes 124a and 124b (fixed portions) at the time of mounting, the mounting holes 124a and 124b serving as mounting bases in the instrument panel 100 are displayed. The vicinity may bend and the assembly property may be lowered.

  Therefore, in the present embodiment, as shown in FIG. 3A, the three-surface rib 150 is disposed in the vicinity of the attachment hole 124a and the attachment hole 124b. Thereby, in the instrument panel 100, the rigidity in the vicinity of the mounting hole 124a and the mounting hole 124b can be improved. Therefore, bending (deformation) in the vicinity of the mounting hole 124a and the mounting hole 124b at the time of mounting the design component 140 can be suppressed, and the assembling property can be improved.

  In the present embodiment, the configuration in which the three-surface rib 150 is provided between the attachment hole 124a and the attachment hole 124b is illustrated, but the present invention is not limited to this. For example, the three-surface rib 150 may be provided on the back surface of either the attachment hole 124a or the attachment hole 124b, or may be provided on one side of the attachment hole 124a or the attachment hole 124b that is not adjacent to the other.

  Further, in the present embodiment, as shown in FIG. 3, the three-surface rib 150 is disposed in the vicinity of the end of the opening 122. As described above, the instrument panel 100 is provided with a plurality of openings (in this embodiment, the opening 122 in which a car navigation (not shown) is arranged is illustrated) for arranging assembly parts (not shown). Yes. These opening portions become larger as the assembly parts to be arranged become larger, and the larger the opening portion, the more easily the end portion is deformed by a load applied during transportation or transportation after molding. Therefore, by arranging the three-surface rib 150 near the end of the opening 122 as in this embodiment, the rigidity of the instrument panel 100 near the end of the opening 122 is improved. Therefore, it is possible to prevent deformation of the end portion of the opening 122 due to a load applied during transportation or transportation of the instrument panel 100 after molding.

  FIG. 6 is an enlarged view of the top surface portion 110 in the vicinity of the opening portion 122 in FIG. 2 and shows a state in which the three-surface ribs 150 and the like provided on the back surface of the instrument panel 100 are transmitted for convenience of explanation. In the top panel 110 of the instrument panel 100 shown in FIG. 6, the curvature changes in the curvature changing sections 112a and 112b. Specifically, in the instrument panel 100, the region on the vehicle width direction outer side (left side) than the curvature change portion 112a is gently inclined downward, and similarly, the vehicle width direction outer side (right side) than the curvature change portion 112b. The region is also gently inclined downward. A region between the adjacent two curvature changing portions 112a and 112b is a region where there is no change in curvature, that is, the flat portion 114. As described above, the flat surface portion 114 having no change in curvature has lower rigidity than the curvature change portions 112a and 112b, and is likely to be sticky when a load is applied.

  Therefore, in the present embodiment, as shown in FIG. 6, the three-surface rib 150 is arranged on the plane portion 114 between the two adjacent curvature change portions 112 a and 112 b. Thereby, since the plane part 114 is reinforced by the three-surface rib 150, it becomes possible to suitably prevent the stickiness that easily occurs there. In the present embodiment, the curvature changing portions 112a and 112b are exemplified as the curvature changing portions of the top surface portion 110 of the instrument panel 100. However, the present invention is not limited to this. The top surface portion 110 may have a curvature changing portion other than the curvature changing portions 112a and 112b. In the curvature changing portions other than the curvature changing portions 112a and 112b, the three-surface rib 150 is disposed between the adjacent curvature changing portions. Thus, the above-described effects can be obtained.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  INDUSTRIAL APPLICABILITY The present invention can be used for an instrument panel that is disposed in the front part of a vehicle and partitions an engine room and a passenger compartment space.
