Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a steering bouncing device capable of bouncing up a steering wheel, for example, while the vehicle is stopped, and more particularly to a bouncing device that enables the bouncing mechanism to operate only when the vehicle is stopped while sharing a tilt mechanism and a bouncing mechanism. Related to the device.
[0002]
[Prior art]
As is well known, in order to improve getting on and off the vehicle, the steering wheel is jumped up to a predetermined evacuation position when getting off, while the steering wheel is moved up to the driving position after getting on. Various devices are provided.
[0003]
In recent years, a steering wheel having a larger flip-up angle has been put to practical use to further improve the getting on / off property, and one of them is described in, for example, JP-A-2000-71798. Things are known.
[0004]
In brief, the steering bouncing device is provided in a vehicle with an automatic transmission (automatic transmission), and can bounce the steering wheel beyond a normal driving angle when the vehicle is idling or when the key is in the ignition-on position. Steering position selecting means, steering position detecting means, shift lever parking position detecting means, foot brake pedal position detecting means, steering moving means, and shift lever locking means for disabling shift selection. And fetching signals from the steering position selecting means, the steering position detecting means, the shift lever parking position detecting means, and the foot brake pedal position detecting means to control the shift lever locking means and the steering moving means. And a tearing movement control means.
[0005]
When the steering wheel is jumping up, the shift lever cannot be selected by the shift lever lock unit even when the foot brake pedal is depressed, and even when the steering wheel position is restored, the steering wheel position is changed to the driving position. If the vehicle is not completely restored to the normal position, the control is performed so that the shift lever locking means cannot be released even if the foot brake pedal is depressed. On the other hand, when the steering wheel completely returns to the driving position, control is performed so as to release the shift lever locking means by stepping on the foot brake.
[0006]
As described above, the shift lever locking means is released by depressing the foot brake only when the steering wheel completely returns to the driving position, so that the steering wheel cannot be operated even when the idle or key IGN is on. When in the right position, even if the foot brake is depressed, shift selection from parking to another range cannot be performed.
[0007]
[Problems to be solved by the invention]
However, the conventional steering jumping device locks the shift lever / lock means when detecting a state where the steering wheel is jumped up or when the steering wheel is not completely returned to the driving position. In addition, since all mechanisms such as the steering movement control means that controls unlocking of the shift lever locking means when the steering wheel is completely returned to the drive position are composed of electric circuits, control is complicated and dedicated In addition to this, there is a problem that the controller is required, and the number of parts is large and the manufacturing cost is high.

[0017]
The movable column portion 5 is formed in an irregular shape having a flange portion 5a for attaching a combination switch (not shown) to the steering wheel 2 side, and is vertically moved around a tilt hinge shaft 8 which is a rotating shaft arranged in the vehicle width direction. And the tilt mechanism 7 allows vertical rotation within a predetermined angle range (approximately 10 ° and approximately 15 ° up and down with respect to the axis of the fixed column unit 4). At the same time, the flip-up mechanism 9 allows the tilt mechanism 7 to allow the tilt mechanism 7 to jump upward (45 ° with respect to the axis of the fixed column portion 4 shown in FIG. 4) in the upward direction. .
[0018]
That is, as shown in FIGS. 1 and 2, the tilt mechanism 7 includes the tilt hinge shaft 8 that supports the movable column 5 and a substantially triangular mounting formed on one side of the movable column 5. The tilt lever 11 is attached to the end of the surface 10 via a lever bolt 11a so as to be rotatable in the front-rear direction. The tilt lever 11 is fixed to the lower end of the fixed column 4 on the movable column 5 side by a bolt 12, and A fixed tooth 13 having a plurality of convex arcuate engaging teeth 13a; and a lower end of the movable column portion 5 which is rotatably provided about a pivot shaft 14 so that each of the fixed teeth 13 And a movable tooth 15 having a plurality of concave arcuate locking teeth 15a meshed with or released from the teeth 13a.
[0019]
The tilt lever 11 has a release protrusion 16 on the lower inner surface for rotating the movable tooth 15 downward to release the engagement of each locking tooth 15a with each engagement tooth 13a, and a lever bolt 11a. A lever spring 17 composed of a torsion coil spring wound on the head side presses the movable tooth 15 in the clockwise direction in FIG. 1, that is, the direction in which the locking teeth 15a mesh with the engaging teeth 13a. Being energized.
[0020]
As shown in FIG. 1, the flip-up mechanism 9 basically shares the components of the tilt mechanism 7, such as the tilt hinge shaft 8, the tilt lever 11, and the fixed-side teeth 13 and the movable-side teeth 15, and has a different configuration. The member is provided with a spiral spring 18 which is an urging member for urging the movable column portion 5 upward (in a flipping direction) around the other side portion of the movable column portion 5, and is shown in FIG. Thus, the movable tooth 15 is completely separated from the fixed tooth 13 so that the movable column part 5 can be flipped up at an angle of about 45 ° with respect to the axis X of the fixed column part 4. It is. As shown in FIG. 2, the outer end of the spiral spring 18 is engaged with a support pin 19 protruding from the other side of the fixed column part 4, while the inner end of the spiral spring 18 is connected to the other end of the movable column part 5. Locked to the side.
[0021]
Further, the jumping-up mechanism 9 controls the rotation of the movable tooth 15 or releases the control when the vehicle is not running, that is, whether the shift lever of the automatic transmission is in the P range position. 20.
[0022]
Further, the flip-up mechanism 9 is linked with a shift lock mechanism 21 shown in FIG. 5 for restricting the shift lever from moving from the P range position to another range when the movable column portion 5 is flipped up. are doing.
[0023]
More specifically, the operation control unit 20 is basically formed of a mechanical member as shown in FIGS. 1 to 4, and is turned around the fixed tooth 13 of the fixed column unit 4 in the vehicle width direction. A lock plate 22 as a lock member movably provided, a stopper lever 23 as an operation member fixed to the mounting surface 10 of the movable column portion 5 with a bolt 10a and engaged and disengaged from the lock plate 22, An electromagnetic actuator 24, which is an actuator fixed to the lower part of the fixed column portion 4 via a bracket along the vehicle width direction, is provided with a detection signal from a P range detection switch 52 to be described later. , The lock plate 22 is rotated in the engagement direction or the engagement release direction.
[0024]
As shown in FIGS. 1 and 3, the lock plate 22 is formed in a substantially rectangular shape that is long in the vertical direction, and has a pivot 26 that is held at a substantially center by a support bracket 25 that protrudes from a side of the fixed column 4. Is formed so as to be rotatable in the width direction of the vehicle body, and a rectangular engaging groove 27 is formed inside the upper end portion to engage and disengage the distal end portion 23a of the stopper plate 23. The lower end of the lock plate 22 is formed with a hole for engaging the L-shaped tip 28 of the drive shaft 24a of the electromagnetic actuator 24.
[0025]
The stopper plate 23 is formed in a substantially rectangular shape as shown in FIG. 1, and a lower end portion is fixed to the mounting surface 10 by the bolt 10a, and a central portion is fixed to the tilt hinge shaft 8 so that the movable column is movable. The unit 5 is configured to rotate integrally with the unit 5 in the vertical direction of the vehicle body. The distal end portion 23a of the stopper plate 23 is formed in a substantially fan shape so that a flat lower end edge 23b is engaged with and disengaged from the engagement groove 27 of the lock plate 22, and the distal end edge 23c is described later. It is formed in an arc shape so as to be able to appropriately contact the flip-up detection switch 53.
[0026]
The flip-up detection switch 53 is provided at the front end of the fixed column portion 4 and is normally turned on. However, when the switch piece 53a is pressed by the tip 23c, the switch 53 is turned off and will be described later. The detection signal of the brake pedal switch 54 is cut off.
[0027]
The electromagnetic actuator 24 is of a so-called solenoid type, and when energization of a built-in coil is cut off, the drive shaft 24 a is urged in a projecting direction by an internal solenoid spring to engage the lock plate 22. The leading end 23a of the stopper plate 23 is engaged with the groove 27 to restrict further rotation of the stopper plate 23 in the counterclockwise direction in FIG. On the other hand, when the coil is energized, the drive shaft 24a moves backward by the electromagnetic attraction force, and the engagement of the stopper plate 23 with the lock plate 22 is released. The electromagnetic actuator 24 is energized by an ON signal from the P range detection switch 52 of the shift lever 40 (the shift lever is in the P range).
[0028]
As the shift lock mechanism 21, a known mechanism can be employed as it is. For example, the same structure as that described in Japanese Patent Application Laid-Open No. 6-249327 filed by the present applicant is adopted, 5, the shift lock mechanism 21 is unitized and mounted on a position plate 30 of a bracket 31 through which a shift lever 40 is inserted and supported, and includes a first operating member 32 and a second operating member 32. An operating member 33, a lock member 34, an electromagnetic drive unit 35, and a unit base 31a are provided.
[0029]
The first operating member 32 is formed in a bell crank shape, and has a base portion pivotally attached to the unit base 31a by a pivot 36. The lower surface of one arm 32a extending toward the position pin 37 is located at a position where the shift lever 40 comes into contact with the position pin 37 when the shift lever 40 is at the P range position P. One end of a key lock cable 38 linked to a key interlock mechanism (not shown) is connected to the tip.
[0030]
The second operating member 33 has a base portion pivotally attached to the bracket 31 by a pivot 36 coaxial with the first operating member 33. An arm portion 33a extending from the base portion to the position pin 37 side is a first operating member. It is arranged below and opposite to the arm 32a. The arm 33a has a protrusion protruding toward the lock member 34.
[0031]
The arm 32a of the first operating member 32 and the arm 33a of the second operating member 33 are urged by a torsion coil spring 39 wound around the pivot 36 so as to be attracted to each other. The position pin 37 at the position P is pressed and held between the arms 32a and 33a.
[0032]
The lock member 34 is formed in a bell crank shape, and has a base portion pivotally attached to the bracket 31 by a pivot perpendicular to the pivot 36. A long hole is formed in one arm of the lock member 34 (not shown), and a hook portion of a plunger 35a of the electromagnetic drive unit 35 described later is engaged with the long hole. Further, the arm on the other side of the lock member 34 moves to a position facing the lower surface of the protrusion of the second operating member 33 when in the P range position P with the rotation of the lock member 34. . Further, a projection 32c is formed on the first operating member 32 facing the arm.
[0033]
When the shift lever 40 in the running position is moved to the P range position P while pressing the knob button 40a, first, the position pin 37 comes into contact with the upper surface of the arm 33a of the second operating member 33. When the shift lever 40 is further moved to the P range position P side, the position pin 37 pushes down the arm portion 33a of the second operating member 33 by the spring force of the torsion coil spring 39, and moves downward to the P range position P. Moving.
[0034]
After that, when reaching the P range position P, the position pin 37 is pressed and held by the arm 32a of the first operating member 32 and the arm 33a of the second operating member 33.
[0035]
Here, when the knob button 40a is released, the position pin 37 is engaged with the upper end of the position groove 30a at the P range position P by the spring force of the compression spring. At the same time, the position pin 37 of the shift lever 40 comes into contact with the contact point of the P range detection switch (micro switch) to be turned on, whereby the solenoid 35 is excited via the controller 50 and the plunger 35a is sucked. As a result, the lock member 34 rotates clockwise in the drawing, and its arm moves to a position facing the lower surface of the projection of the second operating member 33, and locks the shift lever 40 to the P range position P. It has become. Further, the lock member 34 is held at the lock position by abutting on the protrusion 32c of the first operating member 32.
[0036]
Hereinafter, a control configuration of the flip-up mechanism 9 and the shift lock mechanism 21 will be described with reference to FIG.
[0037]
First, when the P range detection switch 52 is turned on, the controller 50 excites the solenoid 35, and when the brake pedal switch 54 is turned on in this state, the controller 50 cancels the excitation of the solenoid 35. ing. In this embodiment, the shift lock mechanism of the energization lock in which the lock member 34 moves to the lock position when the solenoid 35 is excited is described. However, the lock member 34 is activated by the solenoid 35 being excited. In the shift lock mechanism in which the power is released to move to the lock release position, the control is such that the solenoid 35 is excited only when both the P range detection switch 52 and the brake pedal switch are ON.
[0038]
That is, the controller 50 is operated by being supplied with electric power when the ignition key switch 51 is turned on, and controls the operation of the solenoid 35 based on detection signals from the P range detection switch 52 and the brake pedal switch 54. In the flip-up mechanism 9, when the P range detection switch 52 is turned on, a control current is output to the electromagnetic actuator 24 to excite it, and the lock plate 22 is rotated to disengage the stopper plate 23. Release.
[0039]
Here, when the tilt lever 11 is operated to rotate the movable column portion 5 upward beyond the tilt angle range, the flip-up detection switch 53 is pressed, but the flip-up detection switch 53 is normally in the ON state. The switch piece 53a is turned off when the switch piece 53a is pressed, and is provided between the brake pedal switch 54 and the controller 50.
[0040]
That is, even if the brake pedal switch 54 is turned on by depressing the brake pedal, the detection signal of the brake pedal pedal switch 54 is not transmitted to the controller 50 if the flip-up detection switch 53 is in the off state.
[0041]
That is, when the movable column portion 5 is flipped up and the flip-up detection switch 53 is pressed by the leading edge 23c of the stopper plate 23 to switch from the ON state to the OFF state, the detection signal of the brake pedal switch 54 is output to the controller 50. Therefore, even if the brake pedal is depressed and the brake pedal switch 54 is turned on, the controller 50 controls the electromagnetic drive unit 35 of the shift lock mechanism 21 to be in a demagnetized state without supplying power, and the shift lock mechanism 21 The movement of the shift lever 40 from the P range position to another range is restricted.
[0042]
In other words, the controller 50 restricts the shift lever 40 to the P range position by giving priority to this condition when the flip-up detection switch 53 is off.
[0043]
Therefore, according to this embodiment, first, when the shift lever 40 is located at a position other than the P range, that is, for example, when the vehicle is running in the D range, the movable column portion 5 is set to the predetermined driving appropriateness. Since the flip-up detection switch 53 is in the ON state and the P-range detection switch 52 is in the OFF state, the drive shaft 24a is protruded by the spring force of the solenoid spring, and the lock plate 22 is moved. 3, the stopper plate 23 is in a state of engagement with the engagement groove 27 of the lock plate 22 at the tip end 23 a, and the stopper plate 23 is excessively moved beyond the tilt angle range of the movable column portion 5. Restrict the upward rotation. Therefore, the movable column portion 5 is allowed to rotate only within the tilt range by operating the tilt lever 11.
[0044]
Next, when the shift lever 40 is in the P range position, that is, when the vehicle is in a non-traveling state, the P range detection switch 52 is turned on, the power is supplied to the electromagnetic drive unit 35, and the shift lever 40 is locked. become. When the brake pedal is depressed in this state, the brake pedal switch 54 is turned on, the restriction by the shift lock mechanism 21 is released, and the free movement of the shift lever 40 is allowed.
[0045]
When the P-range detection switch 52 is turned on, the controller 50 supplies power to the electromagnetic actuator 24, and the lower end of the lock plate 22 is retracted and rotated to be held at the position indicated by the two-dot chain line in FIG. As a result, the distal end portion 23a of the stopper plate 23 is disengaged from the engagement groove 27 and the engagement is released. Therefore, when the movable lever 15 is disengaged from the fixed tooth 13 by operating the tilt lever 11, the movable column portion 5 can be rotated to a maximum upper position of 45 ° by the spring force of the spiral spring 18.
[0046]
When the movable column part 5 rotates in the maximum upward direction, the flip-up detection switch 53 is turned off at the tip part 23a of the stopper plate 23, so that the shift lever 40 is restricted to the P range position by the shift lock mechanism 21. .
[0047]
Further, even if the brake pedal is depressed in this state, since the flip-up detection switch 53 is still in the OFF state, the restriction of the shift lever 40 by the shift lock mechanism 21 is not released, and the shift lever 40 is moved to the P range position. Hold.
[0048]
For this reason, the vehicle can be reliably prevented from running while the steering wheel 2 is kept being jumped upward by the jumping mechanism 9, so that the safety is also enhanced in this respect.
[0049]
In addition, as described above, when the vehicle is running, the electromagnetic actuator 24 is not energized and the stopper plate 23 is engaged with the lock plate 22, so that the tilt lever 11 is inadvertently operated during running. Even so, the steering wheel 2 is reliably prevented from jumping up.
[0050]
As described above, according to this embodiment, it is possible to prevent the steering wheel 2 from inadvertently jumping up while the vehicle is running, and to jump up only the P range position of the shift lever 40 even while the vehicle is stopped. , Improve safety.
[0051]
In addition, a conventionally known manual tilt mechanism and a shift lock mechanism of a shift lever can be used as they are, and the malfunction can be reliably prevented while sharing the tilt mechanism and the flip-up mechanism by adding a simple structure. . As a result, the number of parts can be reduced, the manufacturing operation can be facilitated, and the manufacturing cost can be reduced.
[0052]
The present invention is not limited to the configuration of the above-described embodiment. For example, the movable column portion 5 can be configured by a mechanical spring such as another torsion spring in place of the spiral spring, instead of the spiral spring. Further, the operation control unit may be configured by other mechanical structures in addition to the lock plate 22 and the stopper plate 23.
[0053]
Further, although the switch and the solenoid are used as the electric means as the P range detecting means, the electric means may be replaced with a mechanical structure. That is, one end of a key lock cable 38 linked to the key interlock mechanism is connected to the first operating member 32 that rotates while contacting the position pin 37 when in the P range position. This key interlock mechanism has a structure in which the ignition key cannot be pulled out unless the shift lever is at the P range position, and the shift lever cannot be moved from the P range position unless the ignition key is inserted. It is done by pushing and pulling. Therefore, the other end of the key lock cable 38 comes to the key lock unit, that is, the steering column. Therefore, by utilizing this, the other end of the key lock cable 38 may be branched, or may be linked to the lock plate 22 using another member. In this case, since all can be performed mechanically, the reliability is high, and the shift lock mechanism can be made exactly the same as the conventional one, so that the number of different parts and the cost can be reduced.
[0054]
In the above-described embodiment, when the shift lever 11 is in the P range position, the electromagnetic actuator 24 is energized, which may cause heat generation and durability. Therefore, as shown by a broken line in FIG. A switch 55 for detecting operation of the lever may be provided so that the electromagnetic actuator 24 is energized when the tilt lever 11 is operated.
[0055]
【The invention's effect】
As is apparent from the above description, according to the first aspect of the present invention, when the vehicle is in a stopped state, the operation control unit controls the tilt of the movable unit by a signal from the stopped state detecting unit that detects this state. The mechanism is allowed to rotate upward from the maximum upper position.
[0056]
For this reason, not only can the occupant get on and off easily be improved, but also during operation of the vehicle, the operation control unit mechanically restricts the movable unit from jumping up. Lifting can be reliably prevented, thereby improving safety.
[0057]
In addition, the present invention can use a conventionally known manual tilt mechanism having a mechanical structure, such as a spiral spring, for raising and lowering the movable portion, and can add a simple structure to the tilt mechanism and the flip-up mechanism. Since the erroneous operation can be reliably prevented while being shared, the number of parts can be reduced. As a result, manufacturing costs can be significantly reduced.
[0058]
According to the second aspect of the present invention, when the vehicle is in a stopped state and the shift lever is located in the P range, the operation control unit is movable by a signal from the P range detecting means that detects this state. The upper part of the tilt mechanism of the section is allowed to rotate upward.
[0059]
For this reason, not only can the occupant get on and off easily be improved, but also because the P-range detection switch is off while the vehicle is running, the operation control unit mechanically jumps up the movable unit. Since the operation is restricted, inadvertent bouncing of the steering wheel can be reliably prevented, thereby improving safety.
[0060]
In addition, the present invention can use a conventionally known manual tilt mechanism having a mechanical structure, such as a spiral spring, for raising and lowering the movable portion, and can add a simple structure to the tilt mechanism and the flip-up mechanism. Since the erroneous operation can be reliably prevented while being shared, the number of parts can be reduced. As a result, manufacturing costs can be significantly reduced.
[0061]
According to the third aspect of the invention, in addition to the operation and effect of the second aspect, the main configuration of the operation control unit is simply a specific and simple mechanical structure of the lock member and the operation member. The work becomes easier, and the cost can be significantly reduced.
[0062]
According to the fourth aspect of the present invention, when the movable portion is in the state of being maximally jumped up by the jumping-up mechanism, even if the shift lever is in the P range position and the brake pedal is depressed, the shift is performed. Since the movement of the shift lever from the P range to another range can be reliably restricted by the lock mechanism, it is possible to prevent the vehicle from running with the steering wheel jumping up.
