Description

  The present invention relates to a steering column device that drives and adjusts a steering shaft in a tilt direction and a telescopic direction.

  The steering column device is an important safety and security component of the vehicle, and it is very important how to control the behavior at the time of the collision in order to ensure the safety of the passenger at the time of the collision. Normally, the steering column device itself is provided with an impact energy absorbing mechanism, and also plays an important role as a support member for an air bag accommodated in the steering wheel.

  In addition, the steering column device is more user-friendly if the steering wheel attached to the tip of the steering shaft can be adjusted in the tilt / telescopic direction according to the physique, body shape and preference of the driver. Conventionally, there are many things that do not have an adjustment mechanism and those that can only adjust the tilt, but in recent years, those that can be adjusted in both the tilt and telescopic directions are increasing along with the trend of improving the comfort and merchantability of vehicles.

Furthermore, there is a tendency for electric adjustments to be preferred over manual adjustments for higher quality. Here, the pivot point for pivoting the tilt is one below the steering column (the vehicle front side) and one above the steering column (the vehicle rear side, that is, the driver side) (patent) Document 1) is known.

  FIG. 1A is a schematic diagram showing an example of the former. In FIG. 1A, a lower column LC is pivotally attached to a vehicle body around a pivot point PV. Thereby, a tilting operation is possible. Further, the upper column UC is movable in the axial direction with respect to the lower column LC. Thereby, a telescopic operation is possible. The upper column UC rotatably supports a steering shaft SS to which a steering wheel SW is attached.

  However, according to the example of FIG. 1A, when the tilting operation and the telescopic operation are performed to the maximum, the center of the steering wheel SW draws a locus in a fan shape as shown by a one-dot chain line. More specifically, the amount of displacement in the tilt direction when the tilt operation is performed at the position closest to the pivot point PV is A, and the displacement in the tilt direction when the tilt operation is performed at the position farthest from the pivot point PV. If the quantity is B, then A <B from the geometric relationship.

  FIG. 1B is a schematic diagram showing the latter example. In FIG. 1B, the lower column LC is fixed to the vehicle body. The upper column UC is movable in the axial direction with respect to the lower column LC. Thereby, a telescopic operation is possible. A holding portion HD that pivots around the pivot point PV is attached to the tip of the upper column UC. Thereby, a tilting operation is possible. The holding portion HD rotatably supports the steering shaft SS to which the steering wheel SW is attached.

  However, according to the example of FIG. 1B, when the tilting operation and the telescopic operation are performed to the maximum, the center of the steering wheel SW draws a locus in a fan shape as shown by a one-dot chain line. More specifically, the amount of displacement in the tilt direction when the tilt operation is performed at the position closest to the pivot point PV is A, and the displacement in the tilt direction when the tilt operation is performed at the position farthest from the pivot point PV. If the quantity is B, then A = B due to the geometric relationship.

  FIG. 2 shows a state where the driver DR sitting on the seat grips the steering wheel SW. Here, the driver DR having a relatively long arm often sets the steering wheel SW at a position away from him. In the case of such a driver DR, since the legs are often long, there is a case where it is desired to position the steering wheel SW further upward in order to secure a margin around the knee. In addition, for those who have long arms or who prefer to drive in a position where their arms are extended, the telescopic position of the steering wheel is often adjusted to the front of the vehicle regardless of the length of the legs. At this time, the radius of action of the hand centered on the shoulder increases, and the adjustment in accordance with the physique and preference of the driver becomes possible as the adjustment range in the vertical direction, that is, the tilt direction is larger. However, according to the configuration shown in FIG. 1A, the closer to the pivot point PV, the smaller the displacement in the tilt direction. In addition, according to the configuration of FIG. 1B, the tilt direction displacement is unchanged regardless of the telescopic position. Therefore, in any configuration, there is a problem that the adjustment range of the steering wheel desired by the driver DR is limited.

  The present invention has been made in view of the problems of the prior art, and an object of the present invention is to provide a steering column device that can increase the degree of freedom of adjustment of the steering wheel.

The steering column apparatus of the present invention is a steering column apparatus that drives a steering column that rotatably supports a steering shaft so that the position of the steering column can be adjusted with respect to a tilt direction and a telescopic direction.
The amount of movement in the tilt direction at the first telescopic position of the steering wheel attached to the steering shaft is greater than the amount of movement in the tilt direction at the second telescopic position closer to the driver than the first telescopic position. It is characterized by that.

  According to the present invention, the amount of movement of the steering wheel attached to the steering shaft in the tilt direction at the first telescopic position is the tilt direction at the second telescopic position that is closer to the driver than the first telescopic position. Therefore, by increasing the degree of freedom of adjustment of the steering wheel, the steering wheel can be set at a desired position regardless of the physique of the driver. The “driver side” generally refers to the rear side of the vehicle provided with the steering column device.

  Furthermore, as shown in FIG. 2, generally, the driver DR visually recognizes the instrument MT (speedometer, tachometer, etc.) on the instrument panel through the upper half of the steering wheel SW, but the sitting height is extremely high. In the case of the driver DR or when the position of the movable seat is adjusted to be higher, even if the steering wheel SW is fully tilted, a part of the instrument MT may be hidden. However, since the amount of adjustment in the tilt direction of the steering wheel is increased by increasing the amount of movement in the tilt direction at the first telescopic position as in the present invention, the visibility of the instrument is also increased regardless of the physique of the driver. .

  It is preferable to drive the steering column so that the position of the steering column can be adjusted with respect to the tilt direction and the telescopic direction using an electric motor. Some so-called electric steering column devices have a function of assisting the driver in getting on and off by displacing the steering wheel forward and jumping upward in response to turning off the ignition switch. However, if the amount of movement in the tilt direction at the first telescopic position is increased as in the present invention, the steering wheel can be lifted upward, so that even a driver with a large trunk can easily get on and off, for example. There is a merit that

  A drive unit that drives the steering column so that the position of the steering column can be adjusted with respect to a tilt direction and a telescopic direction, and the pivot point of the steering column during the tilting operation is disposed on a side farther from the steering wheel than the drive unit; It is preferable.

  In the present specification, the “telescopic direction” refers to the axial direction of the steering shaft, and the “tilt direction” refers to the direction (particularly the vertical direction) intersecting with it.

  Hereinafter, a tilt / telescopic electric steering column apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 3 is a perspective view of the electric steering column apparatus according to the present embodiment, FIG. 4 is a side view of the electric steering column apparatus according to the present embodiment, and FIG. 5 is the present embodiment. FIG. 6 is a top view of the electric steering column apparatus according to the present embodiment.

  The cylindrical column main body 1 is swingable with respect to a bolt LB inserted into a long hole 1a extending along the axial direction at the lower end thereof via a lower bracket 3 fixed to a vehicle body (not shown). It can be attached to a vehicle body (not shown). The housing 10 of the drive unit DU is attached to a vehicle body (not shown) via the upper bracket 2. As shown in FIG. 6, the upper bracket 2 is detachably attached to a detachment plate 4 fixed to a vehicle body (not shown). As shown in FIGS. 4 and 5, the upper bracket 2 and the housing 10 are connected via a bent energy absorbing plate 5. A steering shaft S that connects a steering wheel SW (FIG. 3) and a steering mechanism (not shown) is inserted into the column main body 1, and is rotatably supported by a bearing (not shown).

  FIG. 7 is a perspective view of the drive unit DU shown with the upper bracket 2 attached by bolting or welding, and FIG. 8 is a perspective view of the drive unit DU shown with the upper bracket 2 removed. . In FIG. 8, a first motor 11 and a second motor 21 are fixed to one end of the housing 10. The rotating shaft of the first motor 11 is connected to the first screw shaft 12 via a coupling (or reduction mechanism) (not shown), and the rotating shaft of the second motor 21 is a coupling (not shown). It is connected to the second screw shaft 22 via (or a speed reduction mechanism). The first screw shaft 12 and the second screw shaft 22 extend in parallel to each other and are rotatably supported by a housing (not shown) with respect to the housing 10.

  A first nut 13 is screwed onto the first screw shaft 12. The first nut 13 moves in the axial direction according to the rotation angle of the first screw shaft 12. The first screw shaft 12 and the first nut 13 constitute a first conversion mechanism (sliding screw mechanism).

  The lower ends of the two arm pieces 14 and 15 are pivotally connected to the first nut 13. The upper ends of the arm pieces 14 and 15 are pivotally engaged with the drive shaft 30. The arm pieces 14 and 15 constitute the first link member L1.

  On the other hand, a second nut 23 is screwed onto the second screw shaft 22. The second nut 23 moves in the axial direction according to the rotation angle of the second screw shaft 22. The second screw shaft 22 and the second nut 23 constitute a second conversion mechanism (sliding screw mechanism).

  The lower end of the two arm pieces 24 and 25 is pivotally connected to the second nut 23. The upper ends of the arm pieces 24 and 25 are pivotally engaged with the drive shaft 30. The arm pieces 24 and 25 constitute the second link member L2. The distance A between the two pivot ends of the first link member L1 is equal to the distance A between the pivot ends of the second link member L2 (FIG. 8).

  Both ends of the drive shaft 30 are rotatably attached to the guide plate 31 as shown in FIG. The guide plate 31 is attached to the lower surface of the column main body 1. The first motor 11 and the second motor 21 are supplied with electric power via a switch (not shown) and can rotate independently of each other.

  FIGS. 9A and 10 are side views of the electric steering column apparatus according to the present embodiment, but are simplified relative to FIG. When the column body 1 that is a steering column is tilted, the first motor 11 and the second motor 21 are rotated in opposite directions by the driver's switch operation. Then, since the first screw shaft 12 and the second screw shaft 22 rotate in opposite directions to each other, the first nut 13 and the second nut 23 (see FIG. 9 (a) (not shown), for example, moves in the direction of approaching.

  In such a case, if the movement amounts of the first nut 13 and the second nut 23 are equal, the first link member L1 and the second link member L2 may move closer to each other while pivoting with respect to the drive shaft 30. The drive shaft 30 does not move in the axial direction of the steering shaft S. Therefore, the guide plate 31 is pushed up only in the direction perpendicular to the axis, and the column body 1 swings around the bolt LB together with the steering shaft S, whereby the upward tilting operation is performed. Obviously, if the first motor 11 and the second motor 21 are rotated so that the first nut 13 and the second nut 23 move away from each other, they move downward. The tilting operation is performed.

  On the other hand, when the column main body 1 is telescopically operated, the first motor 11 and the second motor 21 are rotated in the same direction by the driver's switch operation. Then, since the first screw shaft 12 and the second screw shaft 22 rotate in the same direction, as shown by the arrows in FIG. 10, the first nut 13 and the second nut 23 (not shown in FIG. 10). For example, it moves to the steering wheel side.

  In such a case, if the movement amounts of the first nut 13 and the second nut 23 are equal, the first link member L1 and the second link member L2 move while maintaining their postures (tilts). The relative positional relationship with respect to the drive shaft 30 is unchanged, and therefore the guide plate 31 moves only in the axial direction without being pushed up or down. Thus, in the column main body 1, the bolt LB moves along the long hole 1a, and the steering shaft S extends with the bolt LB, so that, for example, a telescopic operation toward the driver side (vehicle rear side) is performed. Obviously, if the first motor 11 and the second motor 21 are rotated so that the first nut 13 and the second nut 23 move away from the driver, A telescopic operation toward the vehicle front side is performed.

  Here, the advantages of the present embodiment will be described with reference to FIG. 9B showing the geometrical relationship during the tilting operation. In FIG. 9B, the center of the bolt LB located away from the steering wheel (driver) side from the drive unit DU is the pivot point PV, the direction along the axis of the screw shaft is the X direction, The orthogonal direction is defined as the Y direction. In the following description, the pivot point PV and the drive point 30 are described as not being offset with respect to the steering shaft S and the axial movement center line of the column main body 1. If the amount is very small, the resulting error can be ignored.

  When the drive shaft 30 is farthest from the driver, the X-direction coordinate is the telescopic lower limit position TP1. On the other hand, when the drive shaft 30 is closest to the driver, the X-direction coordinate is the telescopic upper limit position TP2.

  Further, the steering wheel center point when the drive shaft 30 is at the telescopic lower limit position TP1 is PS1, and the steering wheel center point when the drive shaft 30 is at the telescopic upper limit position TP2 is PS2. If the distance in the X direction between the telescopic lower limit position TP1 and the telescopic upper limit position TP2 is Lt, the X direction distance between the position PS1 and the point PS2 is also Lt. Also, let the distance in the X direction between the pivot point Pv and the point PS2 be L.

  Here, when the second nut 13 and the second nut 23 are moved relative to each other while the drive shaft 30 is held at the telescopic lower limit position TP1, the drive shaft 30 is moved from the tilt lower limit position to the tilt upper limit position. It is assumed that a large amount T is displaced in the Y direction. At this time, if the rotational displacement angle of the drive shaft 30 relative to the pivot point Pv is θ1, the displacement amount of the center point PS1 can be expressed by (L−Lt) sin θ1. On the other hand, when the second nut 13 and the second nut 23 are moved relative to each other while the drive shaft 30 is held at the telescopic upper limit position TP2, the drive shaft 30 has the same maximum position from the tilt lower limit position to the tilt upper limit position. Assuming that a large amount T is displaced in the Y direction, assuming that the rotational displacement angle of the drive shaft 30 with respect to the pivot point Pv is θ2, the displacement amount of the center point PS2 can be expressed by L · sin θ2. Here, when the rotational displacement angles θ1 and θ2 are approximate and are relatively shallow angles (for example, 30 degrees or less), in order to establish (L−Lt) sin θ1 ≦ L · sin θ2, the distance L is very large. It is necessary to take a large size, and the vehicle cannot be mounted. In other words, in the case of a steering column device that can be mounted on a vehicle, (L−Lt) sin θ1> L · sin θ2 always holds. Therefore, the amount of movement in the tilt direction at the first telescopic position TP1 is larger than the amount of movement in the tilt direction at the second telescopic position TP2 on the driver side relative to the first telescopic position TP1, so Regardless of the physique, the steering wheel can be set in the optimum position.

  In the present embodiment, the rising amount T of the column body 1 using the first link member L1 and the second link member L2 is constant regardless of the telescopic position, but (L-Lt) Since it is sufficient to satisfy sin θ1> L · sin θ2, even if the increase amount T1 at the first telescopic position TP1 and the increase amount T2 at the second telescopic position TP2 are changed (T1 <T2) within a range satisfying this. good.

  In particular, when the tilt-away operation is performed, the first motor 11 and the second motor 21 are rotated in the same direction in response to turning off an unillustrated ignition switch. Then, since the first screw shaft 12 and the second screw shaft 22 rotate in the same direction, both the first nut 13 and the second nut 23 move away from the steering wheel. Subsequently, the first motor 11 and the second motor 21 are rotated in opposite directions. Then, since the first screw shaft 12 and the second screw shaft 22 rotate in the opposite directions, the first nut 13 and the second nut 23 move to the sides close to each other. Thereby, since the 1st link member L1 and the 2nd link member L2 push up the column main body 1, a steering wheel can be flipped up to the maximum and a driver | operator's boarding / alighting becomes easy.

  Note that if the first nut 13 and the second nut 23 are adjusted and moved so as to have different movement amounts and speeds, tilting and telescopic operations in arbitrary directions can be performed in combination. Further, if the movement amount or speed of the first nut 13 or the second nut 23 is detected by the sensor and the drive signal to the motor is controlled based on the detected signal, the tilt and telescopic operation or the combined operation is performed. Can be more stable.

  Next, the shock absorbing operation will be described. When the vehicle collides, the driver's body moving forward due to inertia collides with the steering wheel SW (FIG. 3), and when a so-called secondary collision occurs, the impact from the steering wheel SW is caused by the steering shaft S, the column main body. 1, the guide plate 31, the link members L1 and L2, the nuts 13 and 23, the screw shafts 12 and 22, and the housing 10 are transmitted to the upper bracket 2 in this order.

  Since the upper bracket 2 and the detachment plate 4 are engaged and disengaged when a force greater than a predetermined value is applied in the axial direction of the steering shaft S, the upper bracket 2 receiving the impact force is separated from the detachment plate. 4. Detach from the vehicle body. At this time, since the energy absorbing plate 5 as an impact absorbing device is supported by the upper bracket 2, the bending position is displaced between the upper side fixing bolt (not shown) and absorbs energy at that time. It is like that. Here, although the lower bracket 3 remains fixed to the vehicle body, the column main body 1 can move forward along the long hole 1a, so that the impact received by the driver can be reduced. Note that the impact absorbing device may be constituted not only by a plate but also by an energy absorbing member such as a wire. In order to more firmly attach the upper bracket 2 to the vehicle body, the upper bracket 2 and the lower bracket 3 may be coupled, or a part of the housing 10 may be extended and coupled to the lower bracket 3. It is desirable that the coupling portion be separated at the time of collision.

  According to the present embodiment, since the device for driving the column main body 1 in the tilt and telescopic directions is provided as the drive unit DU, a compact configuration can be provided. Further, screw shafts 12 and 22 parallel to the drive unit DU are provided, and are further pivotally attached to the drive shaft 30 at the upper ends of the first link member L1 and the second link member L2, and the same pivot axis line. Since it can be pivoted around, the action points of the tilt / telescopic operation are integrated into one point, and this is attached to the column main body 1 via the guide plate 31 to realize a simple and compact configuration. . One end (drive shaft 30) of the link may be directly connected to the column body 1 without the guide plate 31.

  In the present embodiment, both screw shafts 12 and 22 can be provided with sensors that respectively detect the rotation direction and the rotation angle. For example, it is assumed that the driver sits on the seat and the ignition switch is turned on to drive the first motor 11 and the second motor 21 to bring the steering wheel to the optimum tilt / telescopic position. Here, when the driver turns off the ignition switch, the vehicle determines that the driver will get off, and drives the steering wheel to a predetermined standby position so as not to prevent getting on and off. At this time, the sensor detects the rotation direction and the rotation angle of the screw shafts 12 and 22 and stores them in a nonvolatile memory (or a converted value corresponding to the position of the steering column). Thereafter, when the driver gets on again and turns on the ignition switch, the rotation direction and the rotation angle stored in the memory are read out, and based on this, the first rotation is performed until the screw shafts 12 and 22 are at the original rotation positions. The motor 11 and the second motor 21 are driven in reverse to the retracting operation. As a result, the steering wheel returns to the original tilt / telescopic position.

  FIG. 11 is a cross-sectional view of a main part of an electric steering column apparatus according to a modification. In the above-described embodiment, the column main body 1 is integrated, but in the modification shown in FIG. 11, the column main body 1 is configured by the inner column 1B being slidably fitted to the outer column 1A. The steering shaft S includes an upper shaft S1 and a lower shaft S2, which are rotatably supported by a bearing BRG with respect to the inner column 1B, and are connected to each other so as not to be relatively rotatable and to be relatively movable in the axial direction by serration coupling or the like. Become. By attaching the guide plate 31 to the outer periphery of the inner column 1B and attaching the drive unit DU (see FIGS. 7 and 8) to the guide plate 31, it is possible to have the same function as the above-described embodiment.

  12-14 is a figure which shows the electrically driven steering column apparatus concerning another modification. In the present modification shown in FIG. 12, both ends of the drive shaft 30 are disposed in a rectangular opening 10 a formed on both side walls of the housing 10. It is preferable to attach a cylindrical buffer member 32 made of or resin. About another structure, it is the same as that of embodiment mentioned above. More preferably, a proximity switch (not shown) is provided instead of the buffer member 32 and the motor is stopped in response to the proximity switch being turned on.

  For example, when the first motor 11 and the second motor 21 are rotated in the same direction, the drive shaft 30 is displaced in the left-right direction (here, right) in FIG. Further displacement is limited by abutting against the right edge of the opening 10a. That is, the opening 10a functions as a stopper and can limit displacement in the telescopic direction. At this time, since the buffer member 32 is formed of rubber or resin, even if it makes contact with the opening 10a, the hitting sound is small and the impact force can be reduced. On the other hand, when the first motor 11 and the second motor 21 are rotated in opposite directions, the drive shaft 30 is displaced in the vertical direction in FIG. 13, but the buffer member 32 is located at the upper and lower edges of the opening 10 a of the housing 10. By colliding, further displacement is limited. That is, the opening 10a functions as a stopper, and displacement in the tilt direction can be limited.

  A limited setting procedure at the time of setting the initial origin of the electric steering column device or when the origin setting becomes necessary after that will be described. FIG. 14 shows a state in which the steering wheel is displaced from the origin. In the state shown in FIG. 14, the tilt position is the uppermost position and the telescopic position is the most retracted position. As a driving method, first, the first motor 11 and the second motor 21 are rotated in the opposite directions, are raised in the tilt direction, are brought into contact with the upper edge of the opening 10a, and then the tilt drive is stopped. The first motor 11 and the second motor 21 are rotated in the same direction, retracted in the telescopic direction, brought into contact with the left edge of the opening 10a, the telescopic driving is stopped, and the movement to the origin position is performed. it can.

  As described above, the present invention has been described in detail with reference to the embodiments. However, the present invention should not be construed as being limited to the above-described embodiments, and can be appropriately changed and improved without departing from the spirit thereof. Of course there is. For example, the drive unit DU is disposed on the lower side of the column body 1, but may be disposed on the upper side of the column body 1. Also, if the spiral groove winding directions of both screw shafts are reversed, telescopic driving can be realized by making the rotation direction of the motor the same direction, and tilt driving can be realized by making the rotation direction opposite. Furthermore, a ball screw mechanism can be used instead of the sliding screw mechanism.

  Furthermore, the present invention is not limited to an electric steering column device, and may be applied to a manual steering column device. For example, by planting a pin on the side of the column body, forming a restraint window in which the pin can move in a bracket attached to the vehicle body, and limiting the amount of movement of the pin according to the telescopic position, The amount of movement of the steering wheel in the tilt direction at the first telescopic position can be set to be larger than the amount of movement in the tilt direction at the second telescopic position on the driver side relative to the first telescopic position. The shape of the restraint window is arbitrary. Further, an elastic body may be provided on the pin or the restraint window so as to relieve the impact when it hits the adjustment limit end during the tilt / telescopic adjustment or the impact at the time of collision.
