Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The shock absorbing type steering column apparatus according to the present invention is intended to protect the occupant's life at the time of a collision by making the steering column have a structure capable of absorbing the impact at the time of a collision.

[0002]

2. Description of the Related Art When a vehicle collides, a so-called secondary collision occurs in which a driver collides with a steering wheel, following a so-called primary collision in which the vehicle collides with another vehicle or the like. For the purpose of reducing the impact received by the driver in the event of this secondary collision and protecting the life of the driver, the steering shaft that fixes the steering wheel at one end, the overall length shrinks when a strong impact is applied, It is common practice to use a so-called collapsible steering shaft and a shock absorbing type steering column through which the steering shaft is inserted.

Conventionally, as a shock absorbing type steering column device used for such a purpose, for example,
The one disclosed in -75057 is known.
18 to 20 show the shock absorbing steering column device described in this publication. The illustrated example shows a structure in which a tilt mechanism for adjusting a height position of a steering wheel (not shown) fixed to a rear end portion of the steering shaft 1 is incorporated. The steering column 2 rotatably supports the steering shaft 1 inside, and has a collapsible structure (not shown) provided at an intermediate portion so that the overall length is reduced when a strong axial force is applied. I have to. The overall length of the steering shaft 1 is also reduced when a strong axial force is applied.

A support bracket 3 for supporting the steering column 2 on a vehicle body includes a pair of left and right support plates 4, 4.
Thus, the supported bracket 5 welded and fixed to the lower surface of the intermediate portion of the steering column 2 is sandwiched. Notches 6, 6 are formed on both left and right side walls of the supported bracket 5, and a vertically long slot 7 is formed in a portion of each of the support plates 4, 4 which is aligned with each of the notches 6. , 7 are respectively formed. Then, a coupling nut 9 is screwed into the other end of the coupling bolt 8 which has the cutouts 6, 6 and the elongated holes 7, 7 inserted from one side to the other (from right to left in FIG. 19). The coupling bolt 8 is moved up and down along each of the long holes 7 by the engagement of the head 10 with the side edge of one of the long holes 7, but is not rotated. . The coupling nut 9 is rotatable by a tilt lever 11 (see FIGS. 1 and 2 showing an embodiment of the present invention; omitted from FIGS. 18 and 19). Therefore, by rotating the coupling nut 9 based on the operation of the tilt lever 11 and changing the distance between the coupling nut 9 and the head 10, the steering column 2 to which the supported bracket 5 is fixed is fixed.
Can be fixed to or released from the support bracket 3 to adjust the vertical position of the steering wheel.

Further, a middle portion of the coupling bolt 8 and a portion existing inside the supported bracket 5 is provided with a rear end portion of the energy absorbing member 12 (the front and rear are represented by the traveling direction of the vehicle, and FIGS. 18 and 20). At the right end). The front end of the energy absorbing member 12 (FIGS.
The left end of the steering column 2 is fixed to the lower surface of the intermediate portion of the steering column 2 by welding. Therefore, the rear end of the energy absorbing member 12 is supported by the vehicle body 27 which is not displaced in the event of a collision via the connecting bolt 8 and the support bracket 3, and the front end is a steering column which is displaced forward in the event of a collision. 2 supported. As shown in FIG. 20, the energy absorbing member 12 is formed by punching out a single metal plate having plasticity so that the inner portion of the energy absorbing member 12 is cut out. Are formed in a flat plate shape.

In the case of a conventional shock absorbing type steering column device incorporating such an energy absorbing member 12, an impact force for pushing the steering column 2 forward is applied due to a secondary collision accompanying a collision accident. In this case, the steering column 2 is allowed to be displaced forward while the energy absorbing member 12 is plastically deformed in a direction extending in the front-rear direction. The width dimension of each of the ring portions 13a to 13d provided on the energy absorbing member 12 is largest at the rear end ring portion 13d and gradually decreases toward the front end ring portion 13a.
As the energy absorbing member 12 expands on the basis of the forward displacement, the force required to further displace the steering column 2 forward (extend the energy absorbing member 12) increases. Therefore, the force required to displace the steering column 2 at the time of the secondary collision is initially small, and gradually increases as the displacement advances. As a result, it is possible to efficiently receive the impact force applied by the driver's body hitting the steering wheel, and prevent the driver's body from being seriously damaged.

[0007]

The above-mentioned conventional shock absorbing type steering column apparatus has the following problems. Since the energy absorbing member 12 is one independent part, parts management and assembling work are troublesome, which increases the cost of the shock absorbing type steering column device. In particular, the work of joining the front end portion of the energy absorbing member 12 and the outer peripheral surface of the steering column 2 by welding is required, and the cost is significantly increased due to complicated assembly work. The energy required to extend the energy absorbing member 12 at the time of the secondary collision is initially small and gradually increases. Although this characteristic itself is preferable, it is difficult to change this characteristic, and it may not be possible to cope with a case where the protection of the driver is further enhanced. That is, the members that absorb the impact energy applied to the steering wheel from the driver's body during the secondary collision include the energy absorbing member 12, the steering shaft 1, the steering column 2, and the like. Absorption of the impact energy is performed by these members working together. Therefore, it may be preferable to adjust the characteristics of the energy absorbing member in relation to the characteristics of other members. The conventional structure shown in FIGS. 18 to 20 cannot cope with such a case. The shock-absorbing steering column device of the present invention is designed to eliminate any of the above-mentioned disadvantages.

[0008]

According to the shock absorbing type steering column apparatus of the present invention, a steering column in which a steering shaft for fixing a steering wheel to one end is freely inserted is provided similarly to the above-mentioned conventional shock absorbing type steering column apparatus. A supporting bracket fixed to the outer peripheral surface of the intermediate portion of the steering column and having a notch opened on the rear end side, and a pair of supporting plate portions sandwiching the supported bracket from both sides, and fixed to the vehicle body side And the support bracket, which is supported between the two support plate portions, and is supported and fixed to the support bracket in a state where the notch is inserted, and the support plate portions are attached to both side surfaces of the supported bracket. The support bracket is made of a plastic bolt that can be pressed and a plastically deformable material. And by plastic deformation when the steering column is displaced forward, consisting of an energy absorbing member for absorbing impact energy applied to the steering column.

In particular, in the shock absorbing type steering column device of the present invention, the energy absorbing member and the supported bracket are integrally formed by bending a single metal plate. The part constituting the energy absorbing member has one end coupled to the part constituting the supported bracket and the other end formed as a free end not coupled to any part. Further, a folded portion is provided in an intermediate portion of a portion constituting the energy absorbing member, and in a state where the folded portion is located behind the coupling bolt,
Both side portions of the folded portion are arranged on the upper and lower sides of the connecting bolt.

[0010]

In the shock absorbing type steering column apparatus of the present invention configured as described above, the energy absorbing member and the supported bracket are integrally formed by bending a single metal plate. In addition, simplification and simplification of assembly work can be achieved. At the time of the secondary collision, the coupling bolt comes out of the notch formed in the supported bracket, the steering column is displaced forward, and one end of the energy absorbing member is displaced forward together with the supported bracket.
The folded portion provided at the intermediate portion of the energy absorbing member is handled by the coupling bolt, so that the folded portion moves to the other end. In this way, the energy absorbing member is plastically deformed so as to move the folded portion to the other end side, thereby absorbing the impact energy applied to the steering column and being applied to the driver's body hitting the steering wheel. Reduce the impact. The force (energy) required to move the folded portion to the other end while plastically deforming the energy absorbing member changes according to the width of the folded portion. Therefore, by changing the width of the energy absorbing member, it is possible to arbitrarily adjust the characteristic of the energy absorbing member to absorb impact energy.

[0011]

1 to 7 show a first embodiment of the present invention. The steering column 2 rotatably supports the steering shaft 1 inside, and a collapsible structure (not shown) provided at an intermediate portion.
Accordingly, when a strong force is applied in the axial direction, the overall length is reduced. Of course, the entire length of the steering shaft 1 is also reduced when a strong force is applied in the axial direction.

A support bracket 3 for supporting the steering column 2 on a vehicle body 27 (see FIGS. 18 and 19)
The mounting plate portion 14 and the holding portion 15 are formed by applying press working to a metal plate such as a steel plate, and are fixed to each other by welding or the like. The mounting plate 14 is used to fix the support bracket 3 to the vehicle body 27.
At the time of fixing, the mounting plate portion 14 is mounted and fixed to the vehicle body 27 at a lower portion of the dashboard or the like by a pair of bolts (not shown). The holding portion 15 is formed by bending the metal plate into a U-shape, and has a pair of left and right support plate portions 4, 4. A support bracket 5 welded and fixed to the lower surface of the intermediate portion of the steering column 2 is held between the support plate portions 4 and 4.

The supported bracket 5 has a width slightly larger than the outer diameter of the steering column 2. Therefore, in a state where the inner surfaces of the support plates 4, 4 are in contact with the left and right outer surfaces of the supported bracket 5, the inner surfaces of the support plates 4, 4 and the outer periphery of the steering column 2 are provided. There is a slight gap between it and the surface. Notches 6, 6 are provided on both left and right side walls of the supported bracket 5, and portions of the support plate portions 4, 4 which are aligned with the notches 6, have long vertically extending portions. Holes 7 are formed respectively. Then, a coupling nut 9 is screwed into the other end of the coupling bolt 8 that has the notches 6, 6 and the elongated holes 7, 7 inserted from one side to the other (from right to left in FIG. 2).
The coupling bolt 8 is raised and lowered along each of the long holes 7 by the engagement of the head 10 with the side edge of one of the long holes 7, but is prevented from rotating. .

A base end of the tilt lever 11 is fixedly connected to the outer half (the left half in FIG. 2) of the connecting nut 9.
The coupling lever 9 is rotatable by the tilt lever 11. Therefore, by rotating the coupling nut 9 based on the operation of the tilt lever 11 and changing the distance between the coupling nut 9 and the head 10, the steering column 2 to which the supported bracket 5 is fixed can be moved. The vertical position of the steering wheel can be adjusted by fixing or releasing the fixing to the support bracket 3. The bottom plate 16 of the supported bracket 5 is provided in the width direction of the supported bracket 5 (front and back directions in FIGS. 1, 3, 4, and 7; left and right directions in FIGS. 2 and 6; A projecting ridge 17 is formed to increase the bending rigidity of the bottom plate portion 16. Therefore, when the distance between the pair of support plates 4, 4 is reduced based on the operation of the tilt lever 11, the supported bracket 5 is moved to the support plates 4, 4.
The supporting bracket 5 can be sufficiently supported by the supporting bracket 3 against the supporting bracket 3.

An energy absorbing member 18 is provided between the supported bracket 5 and the connecting bolt 8.
The energy absorbing member 18 is made of a plastically deformable material such as a mild steel plate, and the supported bracket 5 comes out from between the pair of support plate portions 4 constituting the support bracket 3, and the steering bracket 5 is provided. When the column 2 is displaced forward, it undergoes plastic deformation, thereby absorbing the impact energy applied to the steering column 2.

In particular, in the shock absorbing type steering column of the present invention, the energy absorbing member 18 and the supported bracket 5 are integrally formed by bending a single metal plate. One end of the energy absorbing member 18 is a rear edge of the bottom plate 16 (FIG. 1, 3, FIG.
4, 5, 7) and the other end (FIG. 1,
3, 4 and 5) are free ends that are not connected to any part. Further, a folded portion 19 is provided at an intermediate portion of the energy absorbing member 18. That is, one end of the energy absorbing member 18 is formed as a bent portion 20 rising upward from the rear end edge of the bottom plate portion 16, and the upper end of the bent portion 20 is formed in a quarter arc shape. A curved portion 21 bent forward is formed. A flat energy absorbing portion 22 extends forward from the curved portion 21.

When the shock absorbing type steering column device of the present invention is assembled, the energy absorbing member 18 as described above moves the bent and raised portion 20 constituting the folded portion 19 behind the connecting bolt 8 (FIG. 1). (To the right of 3). In this state, of the bottom plate 16 and the energy absorbing portion 22 on both sides of the folded portion 19, the bottom plate 16 is located below the connecting bolt 8, and the energy absorbing portion 22 is connected to the connecting bolt 8. , Respectively.

In the shock absorbing type steering column apparatus of the present invention having the above-described structure, the energy absorbing member 18 and the supported bracket 5 are integrally formed by bending a single metal plate. In addition, simplification and simplification of parts management and assembly work can be achieved. That is, the energy absorbing member 18 and the supported bracket 5 having the shapes shown in FIGS. 4 to 6 and integrally connected to each other are punched and bent into a plastically deformable metal plate such as a mild steel plate. Pressing such as can be easily and inexpensively made. In the parts management and assembly work, the energy absorbing member 18 and the supported bracket 5 can be handled as a single part. Therefore, as described above, cost reduction by simplifying and facilitating the parts management and assembly work can be achieved. I can do it.

When a forward impact load is applied to the steering column 2 during a secondary collision, the supported bracket 5 welded and fixed to the lower surface of the intermediate portion of the steering column 2 is displaced forward. That is, at the time of the secondary collision, the supported bracket 5 is moved forward against the frictional force acting between the left and right outer surfaces of the supported bracket 5 and the inner surfaces of the pair of support plates 4. And a pair of notches 6 formed at the rear end edge of the supported bracket 5,
6, the connecting bolt 8 comes out backward (actually, the connecting bolt 8 remains at the same position, and the supported bracket 5 is displaced forward).

As described above, when the supported bracket 5 is displaced forward together with the steering column 2, one end of the energy absorbing member 18 is connected to the supported bracket 5.
And displaces forward. Then, as shown in FIG. 7, a folded portion 19 provided at an intermediate portion of the energy absorbing member 18 is provided.
Is turned by the connecting bolt 8 so that the folded portion 19 moves to the other end. Thus, the folded part 1
9 to move the energy absorbing member 1 to the other end side.
The plastic deformation of the energy absorbing portion 8 of FIG. 8 absorbs the impact energy applied to the steering column 2 and reduces the impact applied to the driver's body hitting the steering wheel. When the folded portion 19 is moved to the other end of the energy absorbing portion 22 while being handled by the coupling bolt 8 as described above, the other end of the energy absorbing portion 22 is not displaced upward so as to prevent displacement. It is necessary to hold down the edge. If this restraint is not performed, the folded portion 19 will easily come off the coupling bolt 8, and effective energy absorption will not be possible. In the case of this example, as shown in FIG.
Since the lower surface of the steering column 2 restrains the other end of the energy absorbing portion 22 to prevent upward displacement, effective energy absorption can be performed without incorporating a component for suppressing the other end. You.

In the early stage of the secondary collision, immediately after the connecting bolt 8 comes into contact with the front surface of the bent portion 20, the angle of the continuous portion between the bent portion 20 and the bottom plate portion 16 becomes large. In one direction, one end of the energy absorbing member 18 is plastically deformed. The energy required for such plastic deformation is smaller than the energy required for handling the energy absorbing portion 22 by the connecting bolt 8 and moving the folded portion 19 to the tip side of the energy absorbing portion 22. Therefore, the load required to start the plastic deformation of the energy absorbing member 18 in the early stage of the secondary collision can be reduced, and the impact applied to the driver's body can be effectively reduced. When the width of the energy absorbing portion 22 is made uniform over the entire length as in this example, the amount of forward displacement (stroke) of the steering column 2 during a secondary collision and the steering column The relationship with the load required for displacing 2 forward is as shown by the solid line a in FIG.

At the time of a secondary collision, the energy absorbing member 18
The force (energy) required to move the folded portion 19 to the other end of the energy absorbing portion 22 while plastically deforming the energy absorbing portion 22 changes according to the width of the folded portion 19. Therefore, the energy absorbing section 22
By changing the width, the characteristic of the energy absorbing member 18 for absorbing impact energy can be arbitrarily adjusted. For example, as shown in FIG. 9 showing a second example of the embodiment of the present invention,
When the energy absorbing member 18a having the energy absorbing portion 22a whose width is increased on the way is used, the relationship between the stroke and the load is as shown by a broken line b in FIG. Further, as shown in FIG. 10 showing a third example of the embodiment of the present invention, the energy absorbing portion 22b gradually widens in the middle.
When the energy absorbing member 18b having
The relationship between the stroke and the load is as shown by a chain line c in FIG. That is, as in the third example, the energy absorbing unit 2
By making the maximum width of 2b larger than the inner width of the support plate portion 5 and gradually increasing the width of the energy absorbing portion 22b, if there is not enough stroke, the steering column 2 can be moved forward. The displacement can be forcibly stopped, and a large peak load can be prevented from being generated at the time of the stop.

FIG. 11 shows a fourth embodiment of the present invention. In the case of the present example, one end of the energy absorbing member 18c is connected to the front edge (the left edge in FIG. 11) of the bottom plate 16 constituting the supported bracket 5.
Therefore, in the case of this example, the U-shaped folded portion 19 is provided at a portion near one end of the energy absorbing portion 22c. According to the structure of this example using the energy absorbing member 18c having such a shape, the hook () for locking the end of the spring constituting the tilt type steering device is provided on the front end side of the supported bracket 5. When the hook and the energy absorbing member 18c are provided on the same side, for example, in the case where a hook (not shown) is provided, the yield of the metal plate as a material can be improved. The configuration and operation of the other parts are the same as those described in the first embodiment.
This is the same as the example or the second and third examples described above.

Next, FIG. 12 shows a fifth embodiment of the present invention. In the case of this example, the bent and raised portion 20a that constitutes one end of the energy absorbing member 18d is inclined in the direction toward the rear (to the right in FIG. 12) as it goes upward. In the normal state, the energy absorbing member 18
The gap 23 between the folded portion 19 of FIG.
Is interposed.

The case of this example, the energy absorption by the energy absorbing member 18d during a secondary collision, the supporting bracket 5 is a width W ₂₃ minutes of the gap 23 is started after being displaced forwardly. In other words, until the object supporting bracket 5 is displaced forward by the width W ₂₃ minutes of the gap 23, the energy absorbing member 18d is the steering column 2 is not a resistance to be displaced forward. Therefore, at the time of the secondary collision, the start of the forward displacement of the steering column 2 can be smoothly performed, and the impact on the driver's body which hits the steering wheel at the moment of the start of the displacement can be suppressed to a small level. The configuration and operation of the other parts are the same as in the first example or the second to third examples described above.

Next, FIG. 13 shows a sixth embodiment of the present invention. In the case of this example, an annular sleeve 24 is rotatably fitted around the intermediate portion of the coupling bolt 8,
The outer peripheral surface of the sleeve 24 and the inner peripheral surface of the folded portion 19 of the energy absorbing member 18 face each other. In the case of the present embodiment, at the time of a secondary collision, the sleeve 24 rotates around the coupling bolt 8 and handles the energy absorbing portion 22 of the energy absorbing member 18. Therefore, the friction state between the energy absorbing portion 22 and the mating surface changes from sliding friction to rolling friction, and the energy absorbing characteristics of the energy absorbing member 18 can be stabilized. The configuration and operation of the other parts are the same as in the first example or the second to third examples described above.

Next, FIGS. 14 to 16 show a seventh example of the embodiment of the present invention. In the case of this example, a portion 26 located between the pair of left and right side plate portions 25, 25 constituting the supported bracket 5 at a portion near one end of the energy absorbing member 18e (oblique lattice portion in FIGS. 14 to 16). Is set to be the same as the interval between these two side plate portions 25, 25. Therefore, in the case of the present example, the portion 26 is stretched between the pair of side plate portions 25, 25, and when the coupling bolt 8 and the coupling nut 9 are tightened, the side plate portions 25, 25 are connected to each other. Prevents the gap from narrowing.

Generally, the supported bracket 5 has sufficient rigidity and does not need to be reinforced with another part. However, the distance L ₈ between the center of the steering column 2 and the center of the coupling bolt ₈ is increased due to the layout of each member, or the supported bracket 5 is used to reduce the weight.
When the support bracket 5 is thinned, the rigidity of the supported bracket 5 is insufficient, and the supported bracket 5 with respect to the support bracket 3 is irrespective of the tightening of the connecting bolt 8 and the connecting nut 9.
May be insufficient in supporting strength. In such a case, if the supported bracket 5 is reinforced by the portion 26 as in this example, the supporting strength of the supported bracket 5 with respect to the support bracket 3 can be ensured. Other configurations and operations are the same as those of the above-described fourth example shown in FIG.

Next, FIG. 17 shows an eighth embodiment of the present invention. In each of the above-described examples, the shock-absorbing steering column device of the present invention is incorporated in a tilt-type steering device capable of freely adjusting the height position of the steering wheel. The present invention is applied to a structure in which the height position is fixed. For this reason, in the case of this example, the supported bracket 5 is fixed to the upper surface of the intermediate portion of the steering column 2 by welding upside down from the above-described examples. The supported bracket 5 is connected and supported to the support bracket 3a by a connecting bolt 8 inserted into the support bracket 3a fixed to the vehicle body 27. Support bracket 3
The configuration and operation are the same as those in the above-described first example or the second to third examples, except that the height adjustment mechanism for a is omitted and the installation direction of each member is reversed.

The shock absorbing type steering column apparatus embodying the present invention is not limited to the tilt type as described above, but the tilt type pivot column supports the front end of the steering column. , So-called waist tilt,
Alternatively, a so-called swing tilt that pivotally supports an intermediate portion of the steering column may be used.
