Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shift lever device having an impact absorbing structure.
[0002]
[Prior art]
As shown in FIG. 24, the lower end of the shift lever 202 is attached to the control shaft 204, and the control shaft 204 is supported by a shaft 208 supported at both ends by a bearing 206. Thus, when the shift lever 202 is shifted, the control shaft 204 is rotated so that a desired shift range can be selected.
[0003]
However, when a strong force is applied in the axial direction, the shift lever 202 has a weak absorption force for the force.
[0004]
[Problems to be solved by the invention]
This invention considers this fact and makes it a subject to provide the shift lever apparatus which the absorption power of this force improved, when receiving strong force.
[0005]
[Means for Solving the Problems]
  According to the first aspect of the present invention, a shift lever capable of selecting an arbitrary shift range by a shift operation, and a support means for supporting the shift lever so as to be rotatable and breaking when the shift lever receives an impact force in the axial direction. And havingThe support means is a control shaft that is pivotally supported by the bearing portion of the main body, a bracket provided at a lower portion of the shift lever, a shaft support hole that is formed in the bracket, and an insertion hole that is formed in the control shaft. And a pin inserted into the shaft support hole and an escape hole formed in the bracket leaving a thin portion between the shaft support hole and the pin support hole..
[0006]
Usually, the shift lever is rotatably supported by the support means, and an arbitrary shift range can be selected by a shift operation.
[0007]
When the shift lever receives an impact force (strong force) in the axial direction, the support means is broken. By this breakage, the impact force received by the shift lever can be absorbed. That is, in the shift lever device of the present invention, the impact force received by the shift lever is absorbed by the breakage of the support means, so that the absorption force for the impact force is improved as compared with the conventional shift lever device.
[0030]
  In the present invention,The support means is a control shaft that is pivotally supported by the bearing portion of the main body, a bracket provided at a lower portion of the shift lever, a shaft support hole that is formed in the bracket, and an insertion hole that is formed in the control shaft. And a pin inserted into the shaft support hole, and a relief hole formed in the bracket leaving a thin portion between the shaft support hole,Have.
[0031]
Usually, a pin is inserted through the shaft support hole of the bracket and the insertion hole of the control shaft, and the control shaft can be rotated by operating the shift lever to select an arbitrary shift range.
[0032]
When the shift lever receives an impact force in the axial direction, the bracket at the lower end of the shift lever is pushed toward the pin, so that the pin presses the thin portion of the bracket by the reaction, and the thin portion is bankrupt. Due to the breakage of the thin-walled portion, the pin moves into the escape hole and can move to absorb the impact force received by the shift lever.
[0033]
In this way, the impact force received by the shift lever can be absorbed with a simple structure in which the relief hole is formed in the bracket of the shift lever leaving a thin portion.
[0038]
DETAILED DESCRIPTION OF THE INVENTION
  1 and 2 show the present invention.First reference exampleA shift lever device 10 according to FIG.
[0039]
The shift lever device 10 has a shift lever 12 for shifting operation, and the lower end of the shift lever 12 is attached to a lever holder 14.
[0040]
A bracket 16 is formed at the lower end of the lever holder 14 and is attached to a cylindrical control shaft 18. The bracket 16 is connected to the control shaft 18 by a pin 22 so that the lever holder 14 can rotate in the axial direction of the control shaft 18.
[0041]
The control shaft 18 is supported by a shaft 20, and the shaft 20 is supported by shaft support holes 26 of a pair of parallel shaft support plates 24 erected from the main body of the shift lever device 10. Thus, the shift lever 12 can be rotated in the vehicle front-rear direction with the shaft 20 as an axis, and further, can be rotated in the vehicle width direction with the pin 22 as an axis.
[0042]
An intensity gate is provided in the main body of the shift lever device 10, and when the shift lever 12 of the D range (2 range or L range depending on the case) rotates in the N range direction, it hits the N wall 34 of the intensity gate and N It stops at the position of the range (the position indicated by the solid line in FIG. 2), and does not inadvertently enter the R range or the P range (the position indicated by the two-dot chain line in FIG. 2). When the shift lever 12 is rotated in the width direction of the vehicle about the pin 22 as an axis, the shift lever 12 does not hit the N wall 34 and can enter the R range or the P range.
[0043]
A control lever (not shown) projects from the control shaft 18, and a pin of the control lever is connected to the automatic transmission via a transmission mechanism, and the automatic transmission is shifted by operation of the shift lever 12. .
[0044]
One end of the shaft 20 supported by the shaft support hole 26 is prevented by a push nut 21. An enlarged diameter portion 20A is formed at the other end of the shaft 20 to prevent it from coming off. A reinforcing rib 38 is formed between the shaft support plates 24 to reinforce the shaft support plate 24.
[0045]
As shown in FIG. 2, the shaft support plate 24 is formed with a long hole-like escape hole 30 leaving a predetermined thin portion 28 between the shaft support hole 26 and the shaft support hole 26. The thickness of the thin portion 28 is the same between the left and right shaft support plates. The escape hole 30 is formed in parallel to the axial direction of the shift lever 12 when the shift lever 12 is in the N range. The width of the escape hole 30 gradually decreases as the distance from the shaft support hole 26 increases, and is approximately the same width as the shaft diameter of the shaft 20 at a substantially intermediate portion.
[0046]
Therefore, when the shift lever 12 is in the N range and receives an impact force in the axial direction, the shaft 20 presses the thin portion 28 by this impact force, and the thin portion 28 is broken. The impact force is absorbed by this breakage, and the shaft 20 further enters the escape hole 30 and moves. Further, since the width of the escape hole 30 gradually decreases as the distance from the shaft support hole 26 increases, the shaft 20 hits the hole wall of the escape hole 30 during the movement as shown in FIG. Move while spreading. As a result, resistance is generated in the movement of the shaft 20, the damping time of the impact force is lengthened, and the impact force can be absorbed more effectively.
[0047]
When the movement of the shaft 20 that has moved through the escape hole 30 stops, the shift lever 12 enters the center console 36 as shown in FIG. 5, and the head of the shift lever 12 is connected to the seat surface of the seat 32. It becomes almost the same. For this reason, a possibility that an occupant or a load will hit the shift lever 12 again is reduced.
[0048]
The impact force described above refers to the force F when the force F is applied along the axis J of the shift lever 12, as shown in FIG. 23A. As shown, when the force F acts obliquely with respect to the axis J of the shift lever 12, the axis J direction component Fy of the force F in the axis J direction component Fy and the component Fx in the direction perpendicular thereto is expressed as follows. Say. (In the following description, the impact force is defined similarly.) Accordingly, not only when the force F acts along the axis J of the shift lever 12 but also when the force F acts obliquely with respect to the axis of the shift lever 12. But this force F can be absorbed.
[0049]
  next,First reference exampleThe operation of the shift lever device 10 according to FIG.
  In a normal use state, since the shaft 20 is supported by the shaft support hole 26, when the lever holder 14 is rotated by operating the shift lever 12, the control shaft 18 is also rotated and an arbitrary shift range is selected. it can.
[0050]
When the vehicle is traveling, the shift lever 12 is in the D range (2 range or L range depending on the case), but when the shift lever 12 receives an impact force during sudden deceleration of the vehicle, the shift lever 12 is first moved from the D range to the N range. Move to the range. In the N range, since the shift lever 12 hits the N wall 34, it does not move carelessly to the R range or the P range.
[0051]
Next, since the shaft 20 presses the thin portion 28 by the impact force and the thin portion 28 is broken, the impact force is absorbed by the breakage.
[0052]
As shown in FIG. 4, the shaft 20 that has broken the thin portion 28 enters the escape hole 30 and moves. The escape hole 30 gradually decreases in width as it moves away from the shaft support hole 26, and the width at the substantially intermediate portion is the same as the shaft diameter of the shaft 20, so that the shaft 20 is released during the movement. It moves while pushing the width of the relief hole 30 wide. As a result, resistance is generated in the movement of the shaft 20, the damping time of the impact force is lengthened, and the impact force can be absorbed more effectively.
[0053]
  in this way,First reference exampleIn the shift lever device 10 according to the present invention, when the shift lever receives an impact force, the shaft 20 breaks the thin portion 28, so that the absorption force for the impact force is improved as compared with the conventional shift lever device. Yes. Further, the impact force received by the shift lever 12 can be absorbed without increasing the number of parts.
[0054]
In this shift lever device 10, the magnitude of the impact force at which the thin portion 28 is broken can be arbitrarily adjusted by changing the thickness of the thin portion 28.
[0055]
Further, the shape of the escape hole 30 is not limited to the above-described shape, and may be a gently curved shape, for example.
[0056]
  6 and 7 show the present invention.Second reference exampleA shift lever device 40 is shown.
[0057]
This shift lever device 40 has a substantially U-shaped rotating bracket 42, and an insertion hole 46 is formed in an end plate 44 opposed to the rotating bracket 42. A control shaft 48 is inserted into the insertion hole 46 so that the control shaft 48 can rotate together with the rotation bracket 42. An enlarged diameter portion 48A is formed at the end of the control shaft 48 to prevent it from coming off.
[0058]
  The control shaft 48 isFirst reference exampleIn the same manner as described above, the shaft is pivotally supported by a pair of parallel shaft support plates (not shown) standing from the main body of the shift lever device 40.
[0059]
A substantially L-shaped support bracket 50 is provided in a substantially intermediate portion in the longitudinal direction of the rotation bracket 42 in a side view. A thin portion 52 is formed at the base portion of the support bracket 50 to reduce its strength. When the support bracket 50 receives a force of a predetermined value or more from above, the thin portion 52 is broken as shown in FIG. Thus, the support bracket 50 is detached from the rotating bracket 42.
[0060]
A support hole 54 (see FIG. 7) and a support hole 56 are coaxially formed in each of the rotating bracket 42 and the support bracket 50. A lower end of a shift lever 60 in which a shaft hole 58 (see FIG. 7) is formed is disposed between the rotating bracket 42 and the support bracket 50, and a pin 62 is inserted into the support hole 54, the shaft hole 58, and the support hole 56. Is inserted, and the shift lever 60 is pivotally supported. Thereby, the shift lever 60 can be rotated in the vehicle front-rear direction with the control shaft 48 as an axis, and further can be rotated in the vehicle width direction with the pin 62 as an axis.
[0061]
The pin 62 is formed with an enlarged diameter portion 66 that is thicker than the shaft diameter of the pin 62 on one end side. When the pin 62 is inserted into the support hole 54, the shaft hole 58, and the support hole 56, the enlarged diameter portion 66 is formed. It is positioned by hitting the rotating bracket 42.
[0062]
Further, the pin 62 has a broken portion 65 formed by cutting out a broken hole 64 with a predetermined length along the axial direction from one end side, and the strength is weakened. Thereby, as shown in FIG. 8, when a force of a predetermined value or more is applied from a direction perpendicular to the axial direction, the pin 62 is broken at the breaking portion 65.
[0063]
On the other end of the pin 62, a caulking portion 68 that is thinner than the shaft diameter of the pin 62 is formed. After the pin 62 is inserted into the support hole 54, the shaft hole 58 and the support hole 56, the caulking portion 68 is caulked and the diameter thereof is expanded, so that the pin 62 is prevented from coming off.
[0064]
In the shift lever device 40, in a normal use state, as shown in FIG. 7, the lower end of the shift lever 60 is disposed between the rotation bracket 42 and the support bracket 50 and is pivotally supported by a pin 62. As a result, the shift lever 60 is operated to rotate the control shaft 48 to select an arbitrary shift range.
[0065]
When the shift lever 60 receives an impact force in the axial direction at the time of sudden deceleration of the vehicle, the shift lever 60 presses the pin 62 and the pin 62 is broken at the breaking portion 65 as shown in FIG. Further, the thin portion 52 of the rotating bracket 42 is also broken. Due to this breakage, the impact force received by the shift lever 60 is absorbed. Furthermore, the shift lever 60 and the support bracket 50 move downward while being integrated by the pin 62.
[0066]
Thus, the impact force received by the shift lever 60 can be absorbed with a simple structure in which the thin portion 52 is formed in the bracket 42 and the fracture portion 65 is formed in the pin 62.
[0067]
  9 and 10 show the present invention.Second reference exampleA shift lever device 70 which is a modification of the shift lever device 40 according to FIG.
[0068]
  In this shift lever device 70, the present inventionSecond reference exampleSimilar to the shift lever device 40 according to the above, the substantially U-shaped rotation bracket 72 is provided with a substantially L-shaped support bracket 74 in a side view, but the thin portion is formed at the base portion of the support bracket 74. Not formed. As shown in FIG. 11, the two bottom plates 74 </ b> A of the support bracket 74 gradually spread toward the rotating bracket 72, and the space between these bottom plates 74 </ b> A is substantially trapezoidal larger than the cross section of the shift lever 76. A through hole 78 is formed.
[0069]
Similarly to the shift lever device 40, the lower end of the shift lever 76 is disposed between the rotation bracket 72 and the support bracket 74 and is pivotally supported by a pin 80. In the pin 80, a fracture hole 82 is cut out by a predetermined length along the axial direction from one end side to form a fracture part 83, and the fracture part 83 is weakened in strength.
[0070]
On the other hand, a rivet hole 84 is formed on the other end side of the pin 80, and the rivet hole 82 is a broken portion 85 having a low strength. In addition, a rivet 86 is inserted into the rivet hole 84 and caulked to prevent the pin 80 from coming off.
[0071]
Therefore, in this shift lever device 70, as shown in FIG. 12, when an impact force of a predetermined value or more is applied in the axial direction of the shift lever 72, the pin 80 is broken at the break hole 82 and the rivet hole 84. The portion is broken together with the rivet 86, and the impact force is absorbed. Since the support bracket 74 is not formed with a thin portion, only the shift lever 76 moves downward through the hole 78 while the support bracket 74 is integrated with the rotating bracket 72.
[0072]
  FIG. 13 shows the present invention.Third reference exampleA shift lever device 90 according to FIG.
[0073]
In the shift lever device 90, the lower end of the shift lever 92 is attached to the retainer 94. The retainer 94 has a substantially inverted T shape, and the lower end of the shift lever 92 is inserted into and fixed to a cylindrical mounting portion 96 erected substantially at the center.
[0074]
Further, a substantially horizontal portion of the retainer 94 is a cylindrical insertion portion 98, and a bush 100 is fitted at both ends, and the control shaft 102 is inserted.
[0075]
On the other hand, a pair of bearing plates 106 extend downward from the main body plate 104, and a shaft support hole 108 for supporting the control shaft 102 is formed at the center of the bearing plate 106.
[0076]
An enlarged diameter portion 102A is formed at one end of the control shaft 102, and the other end is reduced in diameter and a male screw 102B is cut. In a state where the control shaft 102 is pivotally supported in the shaft support hole 108, one end side is prevented from coming off by the enlarged diameter portion 102A, and the other end side is secured by screwing the nut 110 into the male screw 102B. In this state, an arbitrary shift range can be selected by operating the shift lever 92.
[0077]
The control shaft 102 has a substantially wedge-shaped hollow portion 112 formed from one end side to the other end side. Further, a reduced diameter portion 114 cut from the outer periphery toward the center is formed inside the portion of the control shaft 102 that is supported by the shaft support hole 108. For this reason, the strength of the control shaft 102 is weak at the portion where the reduced diameter portion 114 is formed.
[0078]
Also in this shift lever device 90, normally, since the control shaft 102 is pivotally supported by the shaft support hole 108, an arbitrary shift range can be selected by operating the shift lever 92 and rotating the control shaft 102.
[0079]
When the shift lever 92 receives an impact force in the axial direction, the reduced diameter portion 114 of the control shaft 102 is broken as shown in FIG. By this breakage, the impact force received by the shift lever 92 can be absorbed, and the control shaft 102 falls downward leaving both ends.
[0080]
Further, the impact force received by the shift lever 92 can be absorbed with a simple structure in which a reduced diameter portion is formed on the control shaft 102.
[0081]
Thus, since the impact force received by the shift lever 92 is absorbed by the fracture of the reduced diameter portion 114 formed on the control shaft 102, the number of parts is not increased and the structure is simplified.
[0082]
Note that the breakage of the left and right reduced diameter portions 114 does not necessarily have to be the same. For example, the size of the hollow portion 112 is adjusted to change the cross-sectional area of the left and right reduced diameter portions 114 so that a time difference occurs in the breakage. May be.
[0083]
  FIG. 15 shows the present invention.Fourth reference exampleA shift lever device 120 is shown.
[0084]
In this shift lever device 120, a main body frame 122 is extended downward to form a pair of mounting plates 124, and a substantially inverted triangular connecting plate 126 shown in FIG. It is like that. That is, the shoe plate 132 is inserted into the horizontally long fixing hole 128 formed in the attachment plate 124 and the horizontally long support hole 130 formed in the upper portion of the connection plate 126, and the connection plate 126 is attached to the attachment plate 124. It has been. After the shoe plate 132 is inserted into the fixing hole 128 and the support hole 130, both ends in the insertion direction are caulked and are prevented from being detached. Further, the shoe plate 132 is formed of a material that is weaker than the mounting plate 124 and the connecting plate 126.
[0085]
On the other hand, the lower end of the shift lever 138 is attached to the retainer 140, and the control shaft 134 is inserted into the insertion portion 142 of the retainer 140. A shaft support hole 136 is formed in the lower part of the connecting plate 126, and the control shaft 134 is supported by the shaft support hole 136. As a result, the shift lever 138 is operated and rotated to select an arbitrary shift range.
[0086]
Also in this shift lever device 120, the connecting plate 126 is usually attached to the mounting plate 124, the control shaft 134 is pivotally supported by the shaft support hole 136, and the insertion portion 142 of the retainer 140 is also connected to the control shaft 134. Is pivotally supported. Therefore, an arbitrary shift range can be selected by operating the shift lever 138 and rotating the control shaft 134.
[0087]
When the shift lever 138 receives an impact force in the axial direction, the impact force acts on the shoe plate 132 via the retainer 140, the control shaft 134, and the connecting plate 126, and the shoe plate 132 is broken as shown in FIG. . By this breakage, the connecting plate 126 falls downward, and the impact force received by the shift lever 138 can be absorbed. Note that the breakage of the shoe plate 138 may have a time difference between right and left.
[0088]
Further, the shift lever 138 and the shoe plate 132 are arranged in a straight line, and a special space for attaching the shoe plate 132 is not required.
[0089]
  FIG. 18 shows the present invention.First embodimentA shift lever device 150 is shown.
[0090]
In the shift lever device 150, the lower end of the shift lever 152 is attached to the lever holder 154. The lever holder 154 is bent at a substantially middle portion, and a bracket 156 formed of a pair of parallel plates is formed at the lower portion of the lever holder 154.
[0091]
  A shaft support hole 158 (see FIG. 19) is formed in the bracket 156. With the bracket 156 straddling the control shaft 160, the pin 162 is inserted into the shaft support hole 158, and the lever holder 154 is connected to the control shaft. The shaft 160 is rotatably supported. The control shaft 160 isFirst reference exampleSimilarly to the shift lever device 10 according to the present invention, it is pivotally supported by a shaft support hole of a shaft support plate (not shown) of the main body. Accordingly, the shift lever 152 can be rotated in the vehicle front-rear direction with the control shaft 160 as an axis, and further, can be rotated in the vehicle width direction with the pin 162 as an axis.
[0092]
Above the shaft support hole 158, a long hole-shaped escape hole 166 is formed leaving a predetermined thin portion 164 between the shaft support hole 158 and the shaft support hole 158.
[0093]
In this shift lever device 150, since the lever holder 154 is normally supported by the control shaft 160, an arbitrary shift range can be selected by operating the shift lever 162.
[0094]
When the shift lever 162 receives an impact force in the axial direction, as shown in FIG. 19, the thin portion 164 presses the pin 162, so that the thin portion 164 is pressed against the pin 162 and is broken by the reaction, and the shift lever 162 is broken. Can absorb the impact force received. Further, the lever holder 154 falls downward due to the breakage of the thin portion 164, and the pin 162 enters the escape hole 166.
[0095]
Thus, the impact force received by the shift lever 162 can be absorbed with a simple structure in which the relief hole 166 is formed in the bracket 156 of the shift lever 162 leaving the thin wall portion 164.
[0096]
In this shift lever device 150, the width of the escape hole 166 may be gradually narrowed as it goes upward, and the pin 162 that has entered the escape hole 166 may hit the hole wall of the escape hole 166. As a result, the pin 162 moves while the lever hole 166 is expanded while the lever holder 154 is falling downward, so that the damping time of the impact force becomes longer and the impact force can be absorbed more effectively.
[0097]
Further, since the lever holder 154 is bent at substantially the middle portion, the impact force received by the lever holder 154 is not directly transmitted to the control shaft 160.
[0098]
  20 and 21 show the present invention.Fifth reference exampleA shift lever device 170 according to FIG.
[0099]
In this shift lever device 170, the shift lever 172 is inserted through the guide hole 176 of the cover plate 174, and the lower end of the shift lever 172 is screwed into a screw cylinder 180 standing from a substantially spherical control sphere 178. Cover plate 172 is screwed to shift lever plate 188.
[0100]
The lower half of the control sphere 178 is in surface contact with the inner surface of the control cable 184 formed in a substantially hemispherical shape, and holds the control sphere 178. Further, the left and right sides of the control cable 184 are partially protruded, and a pair of engagement plates 182 protruding from the control sphere 178 are engaged with engagement recesses 186 formed in the protrusions. Accordingly, when the shift lever 172 is operated, the control cable 184 is rotated together with the control sphere 178.
[0101]
Further, a control lever (not shown) projects from the control cable 184, and the pin of the control lever is connected to the automatic transmission via a transmission mechanism so that the automatic transmission is shifted by the operation of the shift lever 172. It has become.
[0102]
On the other hand, a support recess 190 having a substantially square shape is formed in the shift lever plate 188. A cylindrical support tube 196 is disposed at the center of the support recess 190 and is supported by pins 194 that protrude from the approximate centers of the four side walls 192 constituting the support recess 190. When an impact force is applied to the support cylinder 196 from above, the pin 194 is broken as shown in FIG. The pin 194 may be integrally formed with the side wall 192 or may be a separate body.
[0103]
Further, the upper end surface of the support cylinder 196 is curved in a substantially conical shape corresponding to the outer peripheral surface of the control cable 184, and supports the control cable 184 in a rotatable manner without play.
[0104]
In this shift lever device 170 as well, normally, as shown in FIG. 21, the support cylinder 196 is supported by pins 194, and further, the control cable 184 is supported on the support cylinder 196, so that the shift lever 172 You can select any shift range by operating.
[0105]
When the shift lever 172 receives an impact force in the axial direction, the impact force acts on the pin 194 via the control sphere 178, the control cable 184, and the support cylinder 196. Thereby, as shown in FIG. 22, the pin 194 is broken and the impact force received by the shift lever 172 can be absorbed. Also, the support tube 196, the control cable 184, and the control sphere 178 fall downward due to the breakage of the pin 194.
[0106]
In addition, since the impact force acts on the pin 194 via the substantially spherical control sphere 178, even if the direction of the impact force is blurred or eccentric, the pin 194 is surely broken and absorbs the impact force. it can.
[0107]
In each of the above-described embodiments, the floor shift type in which the shift lever device is provided in the center console of the automobile has been described as an example. However, the position where the shift lever device is provided is not limited thereto. For example, an instrument panel shift type in which a shift lever device is provided on the instrument panel may be used.
[0108]
【The invention's effect】
Since the present invention has the above-described configuration, when a strong force is received, the force is absorbed by the breakage of the support means, so that the absorbing power for the force is improved.
