Description

  The present invention relates to a shift lever device having an impact load absorbing function and a shift lever impact absorbing method.

When a predetermined load is applied to the shift lever for the transmission, the holding member that supports the pivot portion that can swing the shift lever releases the coupling, and the shift lever is immersed inside the instrument panel. What has been made is known (see Patent Document 1 below).
JP-A-10-67245

  By the way, in the conventional shift lever device described above, the shift cable connected to the shift lever is positioned on the vehicle front side of the shift lever (pivot portion), and the upper end of the shift cable extends forward from the lower end of the shift lever. It is connected to the tip of the shaped part.

  For this reason, when a collision is applied to the operation portion at the upper end of the shift lever from the diagonally upper rear side and the coupling by the pivot portion is released when the vehicle collides or the like, the shift lever that has moved downward is The shift lever is connected to the hook-shaped portion at the upper end of the shift cable at the time when the movement is restricted (locked) while moving the shift cable located in the position downward through the hook-shaped portion. There is a possibility that the reaction force by the shift lever that moves rearwardly with the shift lever moving as a fulcrum increases.

  Accordingly, an object of the present invention is to alleviate a reaction force when a load is input to the shift lever.

  According to the present invention, the swing support portion that swingably supports the shift lever provided on the instrument panel includes support release means for releasing the support when a load exceeding a specified value is applied to the shift lever. The other end of the connector having one end connected to the lower portion of the swing support portion is disposed on the vehicle rear side of the swing support portion, and the other end of the connector is moved in accordance with the back and forth movement of the shift lever. Thus, the end of the shift cable that moves up and down is connected via a connector.

  According to the present invention, the shift cable is connected to the shift lever via the connector on the rear side of the vehicle from the swing support portion of the shift lever, so that the swing support portion can be applied by a load input exceeding a specified value to the shift lever. When the support by is released and the downward movement of the shift cable is restricted in accordance with the downward movement of the shift lever, the shift lever rotates to the front of the vehicle with the connecting portion of the shift cable connected to the connector as a fulcrum. Therefore, the load input to the shift lever is efficiently absorbed, and the reaction force when the load is input to the shift lever can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a shift lever device 1 according to an embodiment of the present invention. This shift lever device 1 corresponds to a manual transmission, and is arranged in front of a passenger compartment in an automobile as shown in FIG. It is set at the center lower part in the vehicle width direction of the instrument panel 3 located in the section. The instrument panel 3 is provided with a display 5 of the navigation device, an air outlet 7 into the passenger compartment of the air conditioner, and the like, and a bulge protruding toward the rear of the passenger compartment at the lower portion thereof. The shift lever device 1 described above is disposed in the portion 9.

  As shown in FIG. 1, in the shift lever device 1, a shift lever 11 for a transmission is attached to a base bracket 13, and the base bracket 13 is fixed to a member (not shown) on the vehicle body side. The base bracket 13 includes fixing portions 15 that fix the four corners with respect to the vehicle body side member (not shown). The unit 19 is provided.

  The lever mounting portion 19 is inclined so that the vehicle rear side opposite to the fixed portion 15 is a lower portion in the vertical direction from the front side, and the base opposite to the operation knob 21 which is the operation portion of the shift lever 11 is formed on the inclined portion. A through hole 19a into which the end side is inserted is provided.

  As shown in FIG. 3, which is a side view including a partial cross section of the shift lever device 1 of FIG. 1 as viewed from the left side of the vehicle, the above-described through hole 19 a extends along the longitudinal direction of the shift lever 11. There is a cylindrical portion 23 extending inward, and a swinging support portion 27 that supports a spherical pivot portion 25 provided on the proximal end side of the shift lever 11 so as to be swingable. Is provided.

  The swing support portion 27 includes a concave spherical receiving portion 27a that accommodates and supports the spherical pivot portion 25 of the shift lever 11 so as to be slidable and slidable therein, and a lower side opposite to the operation knob 21 of the shift lever 11. The base end portion 29 further protrudes forward (downward) from the swing support portion 27 and is connected and fixed to one end 31 a of the connector 31.

  The shift lever 11 attached to the base bracket 13 in this way is extended so as to intersect in a direction substantially perpendicular to the inclined portion of the lever attaching portion 19, so that the operation knob 21 side is more than the pivot portion 25. It will incline to be behind the vehicle. In this state, as shown in FIG. 2, the shift lever 11 protrudes upward from an opening 9 a formed on the inclined upper surface of the bulging portion 9 in the instrument panel 3.

  Here, as shown in FIG. 3, the swing support portion 27 described above is broken when an impact load F exceeding a specified value acts from the upper part of the operation knob 21 of the shift lever 11 downward in the longitudinal direction. Suppose that the shift lever 11 moves in the input direction of the impact load F and falls off the base bracket 13.

  As a structure in which the swing support portion 27 is broken, a load input test is appropriately performed, and a material that allows the shift lever 11 to drop off when a specified load is input or a shape may be used. The part 27 is provided with a support releasing means.

  The support releasing means is not limited to the above structure, and may be an attachment structure in which, for example, the swing support portion 27 itself is dropped from the cylindrical portion 23 of the base bracket 13. In short, the shift lever 11 has only to be removed from the base bracket 13 when it receives an impact load F that is greater than a specified level.

  Further, the impact load F described above is generated, for example, when a load in the passenger compartment moves forward and contacts the operation knob 21 at the time of a vehicle collision.

  The connector 31 that connects the base end portion 29 of the shift lever 11 is bent so as to extend rearward and upward of the vehicle, and the other end 31b is positioned rearward of the swing support portion 27. . Then, the other end 31b of the coupling tool 31 is connected to the end 35a of the inner cable 35 of the shift cable 33 made of a push-pull cable via the rotation support pin 37 and the terminal fitting 39, thereby constituting the connecting portion 41.

  The outer casing 39 of the shift cable 33 is fixed to the lower part of the lower projecting portion 17 a projecting downward at the lower end portion of the projecting portion 17 of the base bracket 13 via a stopper 41.

  Accordingly, when the shift lever 11 is swung so as to be tilted forward from the neutral position, the inner cable 35 moves upward via the connector 31, and at this time, for example, the third speed is selected as the transmission. On the contrary, when the shift lever 11 is swung so as to be tilted backward from the neutral position, the inner cable 35 moves downward through the connector 31, and at this time, for example, the fourth speed is selected as the transmission. .

  In addition, since the shift lever device 1 of the present embodiment corresponds to that for a manual transmission as described above, in addition to the shift cable 33 described above, the shift lever 11 is swung left and right. A select cable 43 that moves up and down is provided.

  The select cable 43 is formed of a push-pull cable, similar to the shift cable 33, and the upper end of the inner cable 45 is connected to one end of the swing arm 51 on the vehicle rear side via the terminal fitting 47 and the rotation support pin 49. Connected. The other end of the swing arm 49 on the vehicle front side is rotatably connected to and supported by an arm support shaft 53 attached to the base bracket 13.

  Although not shown, the outer casing of the select cable 43 is attached to the lower portion of the downward projecting portion 17a of the base bracket 13 in the same manner as the outer casing 39 of the shift cable 33.

  On the other hand, on the right side of the pivot portion 25 of the shift lever 11, as shown in FIG. 4, which is a view from the A arrow with a part of the shift cable 33 and the select cable 43 shown in FIG. A stud 55 is provided so as to protrude. The tip of the ball stud 55 is connected to the substantially central position in the longitudinal direction of the swing arm 51 described above.

  Therefore, when the swing lever 11 is swung so as to be tilted between the first and second speeds from the neutral position between the third speed and the fourth speed, for example, the swing arm 51 is moved via the ball stud 55. The select cable 43 is displaced so as to rotate upward about the arm support shaft 53. Conversely, when the shift lever 11 is swung so as to be tilted to the right from the neutral position, the swing arm 51 is displaced so that the select cable 43 side is rotated downward about the arm support shaft 53.

  In the shift lever device having such a structure, for example, when a vehicle collides, a load in the passenger compartment moves forward and interferes with the shift lever 11 so that the impact load F is directed downward as shown in FIG. When the impact load F at this time exceeds a specified value, the swing support portion 27 is broken.

  As a result, the shift lever 11 is detached from the base bracket 13, and the shift cable 33 is also moved downward via the connector 31 due to the downward movement due to the drop. When the downward movement of the shift cable 33 is restricted and locked, the shift lever 11 falls to the front of the vehicle with the connecting portion 41 between the connector 31 and the shift cable 33 as a fulcrum. Move while rotating.

  As a result, the impact load F input to the shift lever 11 is efficiently absorbed by the forward movement of the shift lever 11, and the reaction force when the impact load F is input to the shift lever 11 is reduced. Is possible.

  When the shift lever 11 drops and moves downward, the ball stud 55 and the swing arm 51 or the pivot portion 25 are disconnected from each other, so that the select cable 43 restricts the shift lever 11 from moving downward. It will never be done.

  In the above embodiment, the shift lever device 1 corresponding to the manual transmission has been described as an example. However, the present invention can also be applied to a shift lever device corresponding to the automatic transmission.

It is a perspective view which shows the shift lever apparatus concerning one Embodiment of this invention. It is a perspective view of the vehicle interior in the motor vehicle provided with the shift lever apparatus of FIG. It is a side view including the partial cross section seen from the vehicle left side of the shift lever apparatus of FIG.
