Abstract

PROBLEM TO BE SOLVED: To provide an instrument panel which prevents the fracture and breakage of a crosspiece between openings even if the instrument panel receives a prescribed impact force.SOLUTION: A crosspieces 105 of an instrument panel 100 has a surface part 111, a folded part 113 and a rib part 115. The rib part 115 is formed so as to connect the surface part 111 and the folded part 113. The rib part 115 has a salient part 115a which is salient to a rear surface side from an end part. The salient part 115a of the rib part 115 abuts on a receiving hole T100a of a temporary structure T100 by an impact force. Furthermore, since a tip thin-thickness part 113a is formed at the folded part 113, the tip thin-thickness part 113a is bent toward an upper part a13 from a side edge S113a. By this constitution, in the crosspiece 105, the surface part 111 and the folded part 113 are bent to a direction in which the surface part 111 and the folded part 113 approximate each other, and as a result, the bent crosspiece 105 exerts elasticity as a whole, absorbs the impact force, and prevents the fracture and breakage of the crosspiece 105 itself.SELECTED DRAWING: Figure 6

Description

  The present invention relates to an instrument panel, and more particularly, to an instrument panel that prevents breakage and breakage of a crosspiece between openings even when subjected to a predetermined impact force.

  A conventional instrument panel will be described with reference to an instrument panel 2 shown in FIGS. As shown in FIG. 9, a deck cross member 4 extending in the vehicle width direction is connected to the vehicle body floor by a connecting stay 6 inside the instrument panel 2. The connecting stay 6 includes a connecting stay main body 10 and a bracket 12 that engages with a guide pin 8 of the connecting stay main body 10. A collision avoidance structure 20 that extends obliquely downward is formed on the bracket 12, and the in-vehicle devices 14 and 16 are attached to the bracket 12 via the collision avoidance structure 20.

  Next, the displacement operation of the in-vehicle devices 14 and 16 when an impact load of a predetermined value or more is applied will be described. As shown in FIG. 9, when a part 30 of the human body hits the operation surface of the in-vehicle devices 14 and 16 and an impact force F greater than a predetermined value is generated, the impact force F locks the collision avoidance structure 20. The piece 28 is crushed and the set screw 22 moves to the elongated hole 26. Since the collision avoidance structure 20 has a shape inclined downward as a whole, as shown in FIG. 10, the in-vehicle devices 14 and 16 are also guided in the direction of the arrow 32 along the same and displaced together with the deformation of the instrument panel 2. . The locus of the corner 141 of the in-vehicle device 14 in this displacement is a line 34, and avoids the deck cross member 4 as a rigid body. Accordingly, since the in-vehicle devices 14 and 16 do not interfere with the vehicle body side fixing member as a rigid body such as the deck cross member 4 or the like, the original impact mitigating function of the instrument panel 2 is exhibited, and an abnormal impact on the part 30 of the human body. Generation of reaction force is prevented. (See Patent Document 1 above).

Japanese Patent Laid-Open No. 09-048292

  The above-described conventional instrument panel 2 has the following points to be improved. The instrument panel 2 exhibits the original impact mitigating function of the instrument panel 2 when the in-vehicle devices 14 and 16 are mounted. Therefore, when the in-vehicle devices 14 and 16 are not mounted on the instrument panel 2, the instrument panel 2 performs the original impact mitigation function of the instrument panel 2 and when a predetermined impact force is applied. There is a point to be improved that it is impossible to prevent breakage and breakage of itself.

  In general, as a case where the in-vehicle device is not mounted on the instrument panel, for example, when the vehicle is shipped from the factory, the in-vehicle device is not mounted on the instrument panel, and the in-vehicle device is installed at the store. May be installed. On the other hand, as an international technical standard for automobiles, an instrument panel impact test (EC regulation (impact)) at the time of factory shipment exists as an industrial test. For this reason, it is necessary to prevent the instrument panel 2 itself from being broken or broken when a vehicle-mounted device is mounted at a dealer, that is, when the vehicle-mounted device is not mounted on the instrument panel at the time of factory shipment of the vehicle. There is. In addition, when a vehicle-mounted device is not mounted, a temporary structure may be mounted instead of the vehicle-mounted device in order to exert a predetermined impact mitigating function on the instrument panel. In this case, the temporary structure cannot be arranged so as to be flush with the surface of the instrument panel due to various requirements, and may be arranged in a state of being recessed one step. In this way, when the temporary structure is placed in a state where it is one step deeper from the instrument panel, the end of the instrument panel hits the temporary structure and is deformed so that the end opens due to the impact on the instrument panel. As a result, it is necessary to prevent the instrument panel from being broken or broken because the predetermined impact mitigating function cannot be exhibited.

  Accordingly, an object of the present invention is to provide an instrument panel that prevents breakage and breakage of a crosspiece between openings even when a predetermined impact force is applied.

  Means for solving the problems in the present invention and the effects of the invention will be described below.

  An instrument panel according to the present invention is an instrument panel having a plurality of openings and a crosspiece located between the openings, the crosspiece being along the surface of the instrument panel. A surface portion that is positioned, a folded portion that is formed continuously from the front surface portion toward the back surface, and has a thin portion formed at an end portion that faces the back surface side, the surface portion And a rib portion that connects the folded portion and protrudes from the end portion toward the back surface side.

  As a result, in the crosspiece, the surface portion and the folded portion bend in the direction of approaching each other, and as a result, the bent crosspiece exhibits elasticity as a whole, absorbs impact force, and prevents breakage and breakage of the crosspiece itself. it can.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, about the structure similar to a prior art, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  An automotive instrument panel 100 which is an embodiment of an instrument panel according to the present invention will be described below.

1. Configuration of Instrument Panel 100 FIG. 1 shows an external view of the instrument panel 100. The instrument panel 100 is a panel that is disposed in front of the passenger compartment of an automobile and for installing an air conditioner, an audio device, or the like. The instrument panel 100 is integrally formed of resin as in the prior art.

  In the instrument panel 100, openings 101 and 103 for installing an air conditioner and an audio device are formed continuously in the vertical direction. A crosspiece 105 is formed between the opening 101 and the opening 103. In the instrument panel 100, an air conditioner blowing member is attached to the opening 101.

  The dotted line part of the XX cross section of the instrument panel 100 shown in FIG. 1 is shown in FIG. The crosspiece 105 of the instrument panel 100 has a surface portion 111, a folded portion 113, and a rib portion 115. The surface portion 111 is located along the surface of the instrument panel 100. The folded portion 113 is formed continuously from the front surface portion 111 from the surface of the instrument panel 100 toward the back surface.

  The folded portion 113 has a thin tip portion 113a. The thin tip portion 113a is formed at an end portion facing the back side of the instrument panel 100. Rib portion 115 is formed to connect surface portion 111 and folded portion 113. Moreover, the rib part 115 has the protrusion part 115a which protrudes from the edge part to the back surface side.

2. Operation of the instrument panel 100 When an automobile is shipped without installing a strong structure such as an audio device in the opening of the instrument panel 100, the instrument panel 100 is arranged to ensure the strength of the instrument panel 100. A temporary structure (hereinafter referred to as a temporary structure T100) having the same strength as the planned structure is disposed in the opening. An example of the temporary structure T100 is shown in FIG. The temporary structure T100 is formed in the same size as the structure that was to be arranged. Moreover, as temporary structure T100, it forms, for example using iron. This is because it is possible to easily obtain the same strength as that of the structure to be arranged and to reduce the cost. A receiving hole T100a is formed in the temporary structure T100. The receiving hole T100a is formed at a position corresponding to the position where the protruding portion 115a of the crosspiece 105 is formed when the temporary structure T100 is attached to the instrument panel 100.

  FIG. 4 shows a state in which the temporary structure T100 is attached to the opening 103 of the instrument panel 100. FIG. Moreover, the dotted line part of the YY cross section of the instrument panel 100 which attached structure T100 shown in FIG. 4 is shown in FIG. When the temporary structure T100 is installed in the opening 103 of the instrument panel 100, the front surface P100 of the temporary structure T100 is positioned near the end of the folded portion 113 and the front end of the thin-walled portion 113a. Is done. This is to prevent unnecessary objects, such as rust and dust, adhering to the temporary structure T100 from adhering to the instrument panel 100, particularly where it can be seen from the surface.

  The operation of the instrument panel 100 will be described with reference to FIGS. As shown in FIG. 5, when an impact force F is applied obliquely from above the crosspiece 105 of the instrument panel 100, the crosspiece 105 moves obliquely downward (in the direction of arrow a <b> 11). FIG. 6 shows a state where the crosspiece 105 has moved. At this time, since the surface portion 111 and the folded portion 113 of the crosspiece 105 are connected by the rib portion 115, the surface portion 111 and the folded portion 113 maintained a predetermined angle without moving so as to open. Move down in the state.

  And the protrusion part 115a of the rib part 115 contact | abuts to the receiving hole T100a of the temporary structure T100. Furthermore, when the crosspiece 105 tries to move downward, since the tip thin portion 113a is formed in the folded portion 113, the tip thin portion 113a bends upward (in the direction of arrow a13) from the side edge S113a. The rib portion 115 is buckled by bending the thin tip portion 113a from the side edge S113a upward (in the direction of arrow a13).

  As a result, as shown in FIG. 7, in the crosspiece 105, the surface portion 111 and the folded portion 113 bend in a direction approaching each other, and as a result, the bent crosspiece 105 exhibits elasticity as a whole and exerts an impact force. Absorbs and prevents breakage and destruction of the crosspiece 105 itself. Note that by using the temporary structure T100 in which the receiving hole T100a is formed at a position corresponding to the position at which the protruding portion 115a of the crosspiece 105 is formed, the movement of the protruding portion 115a in the left-right direction can be restricted, so that it is more reliable. In addition, the surface portion 111 and the folded portion 113 can be bent in a direction approaching each other.

[Other embodiments]
(1) Temporary structure: In the above-described first embodiment, the temporary structure T100 has a plurality of receiving holes T100a corresponding to the protruding portions 115a, but receives the protruding portions 115a. If it is, it is not limited to the thing of illustration. For example, like the temporary structure T200 shown in FIG. 8, you may make it form the receiving hole T200a which receives the some protrusion part 115a.

  The instrument panel according to the present invention can be used, for example, as an instrument panel for an automobile.
