Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a pedal displacement control structure for a vehicle.

[0002]

2. Description of the Related Art Conventionally, various arrangements have been devised as countermeasures when an external force exceeding a predetermined value acts on a front portion of a vehicle. As an example of this kind of countermeasure, there is a configuration disclosed in Japanese Utility Model Laid-Open No. 1-73664.

[0003] Briefly, as shown in FIG.
In the configuration disclosed in this publication, the steering column 402 covering the steering shaft 400 is
04 and a pair of side plate members 406, a tilt bracket 408, and a shaft 41 penetrating between these side plate members 406 and supporting a lower edge of the steering column 402
0 supports the vehicle.

Further, the tilt bracket 408 described above is used.
A knee protector 412 having a substantially circular arc shape and capable of being elastically deformed is provided below. The knee protector 412 is elastically supported on the lower edge side of the steering column 402 via an elastically deformable stay 414.

According to the above structure, when an external force equal to or more than a predetermined value acts on the front portion of the vehicle, the occupant attempts to inertia move toward the front of the vehicle, and accordingly, the legs of the occupant are bent in the same direction with the knee as a starting point. Try to inertia move to. Therefore, if the knee protector 412 is not provided, the occupant's knee may contact the tilt bracket 408. However, as described above, the tilt bracket 40
If knee protector 412 is arranged below 8, knees of the occupant will only contact knee protector 412.

The configuration of disposing the knee protector 412 is considered to be a significant measure as a countermeasure when an external force equal to or more than a predetermined value acts on the front portion of the vehicle, but as a countermeasure in relation to the occupant's legs. It is also possible to approach from a different viewpoint, and it is important from the viewpoint of multiple protection that the countermeasures in relation to the occupant's legs be multifaceted.

As a result of repeated experiments conceived from such a viewpoint, the inventor of the present invention focused on the deformation and displacement behavior of the body panel and the like when an external force of a predetermined value or more acts on the front portion of the vehicle, and focused on the brake pedal and the like. It has been concluded that controlling the displacement of the vehicle pedal is also a very effective measure.

SUMMARY OF THE INVENTION In view of the above findings, it is an object of the present invention to provide a vehicle pedal displacement control structure which can control displacement of a tread surface of a vehicle pedal when an external force of a predetermined value or more acts on a front portion of the vehicle. is there.

[0009]

According to a first aspect of the present invention, there is provided a vehicle pedal displacement control structure which is displaced substantially toward the rear of the vehicle when an external force of a predetermined value or more acts on the front of the vehicle. A pedal bracket fixed to a vehicle body-side component member, a suspended vehicle pedal having a tread surface which is swingably supported by the pedal bracket and to which a tread force is applied to a lower end portion, and a first vehicle body A second vehicle body-side component, which is disposed substantially rearward of the vehicle-side member and has a substantially higher rigidity in the vehicle front-rear direction than the first vehicle-side member, extends substantially forward of the vehicle. The relative displacement between the first vehicle body-side component member and the second vehicle body-side component member causes the vehicle body pedal to abut on the vehicle pedal and relatively press the vehicle pedal substantially toward the front of the vehicle. Swing the tread of the vehicle pedal around the center axis. And a displacement control means for rotating and displacing the vehicle body substantially toward the front of the vehicle. Further, a relative displacement between the first vehicle body side component member and the second vehicle body side component near the pedal pressing portion in the displacement control means is further provided. It is characterized in that it is connected to the pedal bracket by a connecting member that can buckle when it occurs.

According to a second aspect of the present invention, in the vehicle pedal displacement control structure according to the first aspect, the connecting member is a plate-like member having a substantially U-shaped cross section. It is characterized by.

According to a third aspect of the present invention, in the vehicle pedal displacement control structure according to the first or second aspect, the mounting portion of the connection member on the pedal bracket side is assembled to the pedal bracket together with the brake switch. It is characterized by being attached.

According to the first aspect of the present invention, when an external force equal to or more than a predetermined value acts on the front portion of the vehicle, the first vehicle body side component is displaced substantially toward the rear side of the vehicle. For this reason, the pedal bracket fixed to the first vehicle body-side constituent member is also displaced substantially toward the vehicle rear side. On the other hand, the second vehicle body-side component disposed substantially rearward of the vehicle relative to the first vehicle body-side component has a rigidity in the vehicle front-rear direction that is relatively higher than that of the first vehicle body-side component. Since it is high, it is hardly displaced substantially toward the rear side of the vehicle. For this reason, a relative displacement occurs between the first vehicle body-side component member and the second vehicle body-side component member, and the relative displacement causes the displacement to extend substantially forward from the second vehicle body-side component member to the vehicle front side. The control means abuts on the vehicle pedal and relatively presses it substantially toward the front of the vehicle. As a result, according to the present invention, when an external force equal to or more than a predetermined value acts on the front portion of the vehicle, the tread surface of the vehicle pedal is rotationally displaced substantially forward of the vehicle around the swing center axis of the vehicle pedal. .

Further, according to the present invention, the vicinity of the pedal pressing portion of the displacement control means is provided between the first vehicle body side component member and the second vehicle body.
Since the connection member is connected to the pedal bracket by a buckling member when a relative displacement occurs between the vehicle-side component members, the accuracy of assembling the pedal pressing portion and the vehicle pedal in the displacement control means is improved. Since the connection member can buckle when a relative displacement occurs between the first vehicle body-side component and the second vehicle body-side component, the pressing operation of the vehicle pedal by the displacement control means is performed by the connection member. Is not inhibited by

According to the second aspect of the present invention, since the connecting member is constituted by the plate-like member having a substantially U-shaped cross section, the first vehicle body-side component member and the second vehicle body-side member are formed. The connection member can be easily buckled when a relative displacement occurs between the constituent members.

According to the third aspect of the present invention, the pedal bracket-side mounting portion of the connecting member is mounted on the pedal bracket together with the brake switch, so that the pedal bracket-side mounting portion of the connecting member and the brake switch are mounted. The number of assembling steps can be reduced as compared with the case where attachment is performed separately and independently.

Specifically, a substantially U-shaped clevis 68 in a plan view is attached to the distal end of the push rod 66. Inside the clevis 68, a pedal support portion 56 is disposed in an inserted state. A clevis pin 70 penetrates both sides of the clevis 68 and the pedal support portion 56, and a split pin or the like is engaged with a penetrating end thereof. The push rod 66 and the pedal support 56 are connected to each other so as to be relatively rotatable.

A return spring (not shown) is engaged with the pedal support 56 or the clevis pin 70 of the brake pedal 10, and the return spring always urges the brake pedal 10 in the direction of returning to the initial position. .

An instrument panel reinforcement 74 as a "second body-side component", which is a pipe-shaped high-strength member, is disposed substantially on the vehicle rear side of the brake pedal 10 described above. The instrument panel reinforcement 74 is a member that has been conventionally provided, and is disposed with the vehicle width direction as the longitudinal direction.

A male screw is formed on the outer peripheral surface of the spindle portion 100B of the brake switch 100, and a lock nut 102 is loosely screwed in advance in advance.

When assembling, first, the brake switch 1
00, the lock nut 102 is moved toward the main body portion 100A, and in this state, the support shaft portion 100B is moved to the rear plate portion 32.
Is screwed into the weld nut 88 of the lower end mounting portion 32B by a predetermined amount. Next, the lock nut 102 is attached to the lower end mounting portion 3.
2B, the weld nut 88 and the lock nut 102 are assembled as if the one end 86A of the connection bracket 86 is sandwiched.

Further, one end 86 of the connection bracket 86
A is fixed to the lower end mounting portion 32B of the rear plate portion 32 by spot welding. In addition, the spot welding portion is attached to one end 8 using the assembly of the brake switch 100.
Since 6A is fixed to the lower end mounting portion 32B, only one corner of the one end portion 86A is provided.

A metal pedal stopper 104 formed in a U-shape in a side view near the middle portion in the longitudinal direction of the brake pedal 10 is fixed by welding to the pedal support portion 56 side of the brake pedal 10.

Next, the operation and effect of this embodiment will be described. First, the overall operation and effect when an external force equal to or more than a predetermined value acts on the front portion of the vehicle will be outlined.

When an external force greater than a predetermined value acts on the front portion of the vehicle, the load at that time may be input to the dash panel 16 via the master cylinder 22 and the brake booster 20. In this case, as shown in FIG. 2, the dash panel 16 is displaced substantially toward the vehicle rear side. Therefore, a load substantially toward the vehicle rear side is input to the base plate portion 28 side of the pedal bracket 26, and the pair of side plate portions 30 buckle substantially in the vehicle front-rear direction due to the load.

On the other hand, since the instrument panel reinforce 74 to which the pressing member 80 is attached is a high-strength member, the instrument panel reinforce 74 is hardly displaced substantially toward the rear of the vehicle. Accordingly, a relative displacement in the vehicle longitudinal direction occurs between the dash panel 16 and the instrument panel reinforcement 74 and the pressing member 80.
At this time, a relative displacement occurs between the pressing portion 80A of the pressing member 80 and the connection portion of the pedal bracket 26 with the connection bracket 86.

Therefore, the intermediate portion 8 of the connection bracket 86
6C is subjected to a compressive load substantially in the vehicle longitudinal direction, and the compressive load causes the intermediate portion 86C of the connection bracket 86 to buckle substantially in the vehicle longitudinal direction. As a result, the pressing portion 80A of the pressing member 80 is attached to the pedal supporting portion 56 of the brake pedal 10.
The engagement protrusion 84 formed in the contact is made. For this reason, the pressing member 80, which has been directed substantially obliquely forward and downward, is rotationally displaced while being plastically deformed substantially toward the lower side of the vehicle. It is relatively pressed downward.

When the pedal support 56 is pressed substantially downward in the vehicle, the rear end of the pedal bracket 26 supporting the same is also pressed in the same direction. For this reason, a detachment load acts substantially on the lower side of the vehicle on the upper end mounting portion 32A side of the rear plate portion 32, and the upper end mounting portion 32A
While being deformed from the bent state (assembled state) to the upright state, the periphery of the bolt insertion hole 42 formed in the upper end mounting portion 32A is plastically deformed and detached from the head of the mounting bolt 44.

After disengagement, the brake pedal 10 is pressed toward the front of the vehicle around the rotation shaft 60 by the pressing portion 80A of the pressing member 80 in accordance with the relative displacement between the dash panel 16 and the instrument panel reinforcement 74. become.
In other words, according to the present embodiment, it is possible to control the pedal pad 58 of the brake pedal 10 to be displaced substantially toward the front of the vehicle when an external force equal to or greater than the predetermined value acts on the front of the vehicle. . As a result, it is possible to suppress bending of the knees of the legs due to the inertial movement of the occupant when an external force equal to or more than the predetermined value acts on the front portion of the vehicle, and thus it is possible to keep the knees of the occupant's legs away from the steering column. .

Next, the function and effect of the main part of this embodiment will be described. In the present embodiment, the pressing member 8
0, the vicinity of the pressing portion 80A and the lower end mounting portion 32B of the rear plate portion 32 of the pedal bracket 26 are connected by the connection bracket 86 that can buckle when a relative displacement occurs between the dash panel 16 and the instrument panel reinforcement 74. The brake pedal 10 supported by the pressing portion 80A of the pressing member 80 and the pedal bracket 26 (more specifically, the engagement projection 8 provided on the brake pedal 10)
4) can be improved. As a result, according to the present embodiment, the pressing portion 80A of the pressing member 80
The transmission efficiency of the pressing force (pressing load) from the vehicle to the brake pedal 10 can be improved, and when an external force of a predetermined value or more acts on the front portion of the vehicle, the pedal pad 58 of the brake pedal 10 is effectively moved substantially in front of the vehicle. It can be displaced to the side.

In this embodiment, the connection bracket 8
6 is formed of a plate-like member having a substantially U-shaped cross section, so that when the dash panel 16 and the instrument panel reinforcement 74 are displaced relative to each other, the connection bracket 8 is formed.
6 can be easily buckled. As a result, it is possible to improve the assembling accuracy of the pressing portion 80A of the pressing member 80 and the brake pedal 10 and to easily buckle when a relative displacement occurs between the dash panel 16 and the instrument panel reinforcement 74 with a simple configuration. Can be done.

Further, according to the present embodiment, one end 86A of the connection bracket 86 is
0 together with the lower end mounting portion 32B of the rear plate portion 32.
