  By the way, in the above-described vehicle shift operation device, the operability of the shift lever is impaired when the unevenness of the unevenness surface of the moderation mechanism is large, but when the unevenness of the unevenness portion is reduced, the shift lever becomes difficult to stop. There has been a problem that erroneous operations are likely to occur.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a shift operation device for a vehicle capable of reducing occurrence of erroneous operation without significantly impairing the operability of a shift lever. Is to provide.

  The gist of the first invention is that a shift lever supported by a support provided in a vehicle so as to be rotatable about one axis and selectively operated to any one of a plurality of shift positions, and an uneven surface A concave and convex member provided on one of the support and the shift lever, and being constantly urged toward the concave and convex surface provided on the other of the support and the shift lever and contacting the concave and convex surface A deceleration mechanism having a moderation mechanism, and a moderation mechanism for a vehicle, wherein the elastic member has a bottom portion of the uneven surface so that the operation resistance increases as the shift lever is rotated faster. A convex portion is provided on an intermediate surface between the bottom and the top of the uneven surface so that the operation resistance increases as the shift lever is rotated more slowly. Some that are.

  According to the first invention, the elastic member is provided on the intermediate surface between the bottom and the top of the uneven surface so that the operation resistance increases as the shift lever rotates faster. With this configuration, when the driver performs a sudden shift operation, a large operation resistance can be given to the driver at a shift position where the shift lever is desired to be stopped, for example, at a D position for forward running. . Alternatively, a convex portion is provided on an intermediate surface between the bottom and the top of the uneven surface so that the operation resistance increases as the shift lever is rotated more slowly. With this configuration, it is possible to provide the driver with a large operation resistance in a shift position where the driver wants to stop the shift lever when the driver performs a slow shift operation, for example, in an R position for reverse running. . Therefore, erroneous operation can be suppressed without significantly impairing the operability of the shift lever.

  In one embodiment of the present invention, the elastic member is a concave elastic member, and the intermediate surface provided with the concave elastic member is an intermediate surface in a concave portion corresponding to a forward traveling D position in the concave and convex shape surface. .

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following examples, the drawings are simplified or modified as appropriate for explanation, and the dimensional ratios, shapes, and the like of the respective parts are not necessarily drawn accurately.

  FIG. 1 is a cross-sectional view of the vicinity of a shift lever 12 of a shift operation device 10 for a vehicle according to an embodiment of the present invention, showing a cross-section including a center axis L1 of the shift lever 12 viewed from a left side of the vehicle. is there. The vehicle speed change operation device (hereinafter, speed change operation device) 10 includes a case 14 and a shift lever 12. The case 14 is a housing obtained by molding a hard resin or a metal plate into a predetermined shape, for example, and is provided fixed to the inside of the vehicle. The shift lever 12 is supported by a case 14 so as to be rotatable around a rotation axis C2, for example, in the front-rear direction of the vehicle, by a rotation shaft 12a formed at the lower end of the shift lever. A guide hole 18 for guiding the shift lever 12 is provided in an upper portion of the case 14 while the shift lever 12 is rotatably inserted in the front-rear direction of the vehicle. The case 14 corresponds to a support that supports the shift lever 12.

  The shift lever 12 is operated according to the driver's intention to select a traveling position, and includes, for example, a P (parking) position, an R (reverse) position, an N (neutral) position, a D (drive) position, and a B (drive) position. The brake is selectively turned to any one of the five shift positions of the brake position. As a result, the "P travel position" for parking, the "R travel position" for reverse travel, the "N travel position" for interrupting power transmission, the "D travel position" for forward travel, and travel with the engine brake applied The five running positions of the "B running position" for the engine brake running are alternatively selected. In the present embodiment, the shift position is arranged such that when the shift lever 12 is rotated from the front side to the rear side of the vehicle, the position is switched in the order of the P position, the R position, the N position, the D position, and the B position. I have.

  The speed change operation device 10 includes a moderation mechanism 20 between the case 14 and the shift lever 12. The moderation mechanism 20 includes an uneven member 22 having an uneven surface and provided in the case 14, and a check device 26. The check device 26 includes a roller 26c which is provided on the shift lever 12 and is constantly urged toward the uneven surface 28 of the uneven member 22 via a plunger 26b by a spring 26a. This gives the driver a sense of moderation for each shift position.

  The uneven member 22 is made of, for example, a resin, and is fixed to the inside of the case 14 by, for example, a screw. Further, the uneven surface 28 is formed on the surface of the uneven member 22 on the shift lever 12 side. The recesses 30p, 30r, 30n, 30d, and 30b as the plurality of recesses 30 on the uneven surface 28 correspond to a plurality of shift positions, ie, a P position, an R position, an N position, a D position, and a B position. I do.

  The roller 26c at the tip of the check device 26 is attached via a plunger 26b to the tip of a spring 26a provided in the check device 26, and is constantly urged by the spring 26a toward the uneven surface 28 of the uneven member 22. ing. The roller 26c corresponds to a rolling element.

  FIGS. 2 to 5 are views showing a state in which the roller 26c moves on the surface of the uneven surface 28 by the turning operation of the shift lever 12 by the driver. The shift position can be changed by the driver turning the shift lever 12 so that the roller 26c, which has been accommodated in the concave portion 30 of the uneven surface 28, rides over the convex portion 32 or the concave portion 30 of the uneven surface 28, and the driver intends to change the shift position. This is performed by fitting into the recess 30 corresponding to the shifted position. Then, the traveling mode of the vehicle is changed by transmitting the changed shift position to a vehicle control device (not shown) by, for example, an electric signal.

  FIG. 2 is a diagram illustrating a state in which the roller 26c passes through the concave portion 30d corresponding to the D position by the slow operation of the shift lever 12 in the speed change operation device of FIG. The concave portion 30d of the uneven surface 28 has an intermediate surface 40 between a bottom portion 36 which is the lowest point of the concave portion 30d and a top portion 38 which is the highest point of the convex portion 32. The intermediate surface 40 is a flat surface or a curved inclined surface. A concave cushion member 44 is inserted and provided in the bottom portion 36 of the concave portion 30d and the intermediate surfaces 40 on both sides by, for example, insert molding or press fitting. The material of the inserted concave cushion member 44 may be any elastic material that is not damaged by the roller 26c, and is, for example, an elastomer, preferably a hardness (JIS K6253) using a durometer type A (measuring time 15 seconds). ) Is used, for example, silicone rubber or Perprene (registered trademark). In this embodiment, the concave cushion member 44 is a concave elastic member having a thickness of about 5 mm from the surface of the intermediate surface 40.

  In FIG. 2, the recess 30d is located between the recess 30n and the recess 30b, and the roller 26c is rotated by the driver from the recess 30n to the recess 30b slowly, that is, by a slow operation. For this reason, the concave cushion member 44 receives almost only the energy due to the urging force of the spring 26a and hardly deforms, and as shown by a dashed arrow L2 indicating the movement of the center of the roller 26c, the roller 26c is It moves along the surface of 44. Therefore, the shift lever 12 receives only a relatively small constant operating resistance.

  FIG. 3 is a diagram illustrating a state in which the roller 26c passes through the concave portion 30d corresponding to the D position by a quick operation of the shift lever 12 in the speed change operation device 10 of FIG. Also in FIG. 3, the recess 30d is located between the recess 30n and the recess 30b, and the roller 26c is turned by the driver, for example, from the recess 30p to the recess 30b at the rear, that is, by a high-speed operation. Have been allowed. For this reason, since the energy from the roller 26c by a quick operation is applied to the concave cushion member 44 in addition to the energy by the urging force of the spring 26a, the concave cushion member 44 is dented and the inclination of the intermediate surface 40 with respect to the roller 26c is reduced. Since it becomes sudden, the driver needs to add a force to be applied to the shift lever 12 or stop the operation of the shift lever 12. Therefore, as indicated by a dashed arrow L3 indicating the movement of the center of the roller 26c, the movement of the roller 26c becomes irregular, so that the operation resistance increases. That is, the faster the shift lever 12 is rotated, the more the concave cushion member 44 is deformed, so that the operation resistance is increased. Thus, when the shift lever 12 is operated from the P position to the D position and when the shift lever 12 is operated from the B position to the D position, the shift lever 12 can be easily stopped at the D position even in a fast operation.

  In the conventional shift operation device, even if the driver intends to move the shift lever from the shift position intended by the driver, for example, from the P position or the B position to the D position, the driver must exceed the D position that the driver wants to stop by operating the shift lever suddenly. There was a possibility that the shift lever would enter a different shift position than intended. In order to prevent this, for example, if the spring force of the spring for urging the roller of the detent mechanism is increased to increase the positioning force, the shift lever becomes difficult to move and the operability is impaired. Therefore, it has been difficult for the conventional shift operation device to prevent both erroneous operation and operability.

  In addition, for example, in order to prevent the shift lever from accidentally entering the B position, the shift lever may be provided with a knob button that must be pressed when operating the shift lever from the D position to the B position. . However, as shown in Patent Document 1 (Japanese Patent Application Laid-Open No. 2017-081332), since the knob button of the shift lever usually has to be pressed when releasing the P position, the shift from the P position to the D position is performed. When operating the lever, the knob button is kept depressed, and the erroneous operation of shifting the shift lever to the B position without stopping at the D position cannot be prevented. Further, if the driver continues to mistakenly recognize that the shift lever has been shifted to the D position while the shift lever is located at the B position due to an erroneous operation, the vehicle continues to run in the B travel position, so that the transmission load is increased. There was a problem of becoming.

  In the shift operation device 10 of the present embodiment, a shift lever 12 supported by a case 14 provided in a vehicle so as to be rotatable about one axis C1 and selectively operated to any one of a plurality of shift positions is provided. An uneven member 22 having a shape surface 28 and provided on one of the case 14 and the shift lever 12 and an uneven surface 28 provided on the other of the case 14 and the shift lever 12 and constantly urged toward the uneven surface 28. And a moderation mechanism 20 having a roller 26c that comes into contact with the shift cushion 12. The concave cushion member 44 has an uneven surface so that the operation resistance increases as the shift lever 12 rotates faster. 28 is provided on an intermediate surface 40 between the bottom 36 and the top 38. For this reason, for example, a change from a predetermined shift position, such as a D position, in which a sudden shift position change is difficult to be tolerated, or in which a shift lever 12 is not desired to be passed during a sudden shift position change. In addition, when the driver performs an abrupt operation of the shift lever 12, an operational resistance can be given to the driver, so that erroneous operation can be suppressed. Further, when the driver operates the shift lever 12 having a low speed, for example, when operating the shift lever 12 at a normal speed, the operability of the shift lever 12 is not so large because the operation resistance is small. It doesn't have to be damaged.

  On the other hand, in the concave portion 30r corresponding to the R position, a convex cushion member 46 is provided so as to give an operation resistance to the driver when the driver operates the shift lever 12 slowly. FIG. 4 is a diagram showing a state in which the roller 26c passes through the concave portion 30r by a quick operation in the speed change operation device 10 of FIG. In FIG. 4, the concave portion 30r of the concave-convex shape surface 28 has an intermediate surface 56 between the bottom portion 52 which is the lowest point of the concave portion 30r and the top portion 54 which is the highest point of the convex portion 56. The intermediate surface 56 is a flat surface or a curved inclined surface. In FIG. 4, the recess 30r is located between the recess 30p and the recess 30n. The convex cushion member 46 is fixed to the intermediate surface 56 of the concave portion 30r on the concave portion 30n side by, for example, insert molding, press fitting, vulcanization, or the like. In the present embodiment, the convex cushion member 46 is a convex elastic member provided so as to partially protrude from the intermediate surface 56 by, for example, about 2 mm. The convex cushion member 46 corresponds to a convex portion.

  In FIG. 4, the roller 26c is rotated slowly by the driver from the concave portion 30p to the concave portion 30n, that is, by a slow operation. When the roller 26c of the shift lever 12 comes into contact with the convex cushion member 46, to move the roller 26c to the concave portion 30n, the driver applies a force to the shift lever 12 to cause the roller 26c to ride over the convex cushion member 46. There is a need. At this time, the movement of the roller 26c becomes irregular, as indicated by a dashed arrow L4 indicating the movement of the center of the roller 26c. As described above, when the shift lever 12 is rotated slowly, a large operation resistance is applied to the shift lever 12.

  FIG. 5 is a diagram illustrating a state in which the roller 26c of the shift lever 12 passes through the concave portion 30 corresponding to the concave portion 30r by a quick operation in the speed change operation device 10 of FIG. In FIG. 5, the concave portion 30r is located between the concave portion 30p and the concave portion 30n, and the roller 26c of the shift lever 12 is quickly turned from the P position to the N position by the driver, that is, rotated by a quick operation. . For this reason, the convex cushion member 46 receives the energy from the shift lever 12 due to the quick operation and is recessed in the direction inside the intermediate surface 56, so that the driver does not need to apply further force to the shift lever 12, and the roller 26c It can be turned to the N position. Therefore, as indicated by the dashed arrow L5 indicating the movement of the center of the roller 26c, the roller 26c moves on a substantially regular trajectory. That is, as the driver rotates the shift lever 12 faster, the operation resistance is not applied to the shift lever 12. In other words, a larger operation resistance is applied to the shift lever 12 as the shift lever 12 is rotated more slowly.

  In a conventional shift operation device, for example, when traveling backward, the driver performs an operation while confirming the rear of the vehicle visually or on a screen, so that even if the driver operates the shift lever slowly, the driver may erroneously shift. There was a possibility that the lever was put into the shift position where the vehicle traveled forward. In order to prevent this, for example, when the roller corresponding to the R position is formed in a shape that makes it difficult for the roller to come out, when the R position is between the P position and the D position, when changing from the R position to the D position, There is a problem that the operability of the shift lever is always impaired.

  However, in the shift operation device 10 of the present embodiment, the convex cushion member 46 is provided between the bottom 36 and the top 38 of the uneven surface 28 so that the operation resistance increases as the shift lever 12 is rotated more slowly. Provided on surface 40. For this reason, for example, it is difficult to allow a slow shift position change, such as the R position, or to prevent the shift lever 12 from passing through the shift lever 12 at the time of a slow shift position change. On the other hand, when the driver operates the shift lever 12 that is slow, a large operation resistance can be given to the driver, so that erroneous operation can be suppressed. In addition, when the shift lever 12 is operated at a high speed, for example, when the shift lever 12 is operated at a normal speed, the operability of the shift lever 12 is not significantly impaired because the operation resistance is small. Only

  Further, in the present embodiment, in the concave portion 30d corresponding to the D position, the concave cushion member 44 is provided between the bottom portion 36 and the top portion 38 of the uneven surface 28 so that the operation resistance increases as the shift lever 12 is rotated faster. The convex cushion member 46 is provided with the bottom 52 of the uneven surface 28 so that the operation resistance increases as the shift lever 12 is rotated more slowly in the concave portion 30 r provided on the intermediate surface 40 and corresponding to the R position. Since the shift lever 12 is provided on the intermediate surface 56 between the top portions 54, when the shift lever 12 is rotated quickly from the P position, the operation resistance increases at the D position, and the shift lever 12 is rotated slowly from the P position. In this case, the operation resistance increases at the R position. Therefore, by stopping the rotation operation when the operation resistance becomes large, it is possible to select the shift position to some extent by the rotation speed, and it is possible to improve the operability of the shift lever 12.

  Although the embodiments of the present invention have been described in detail with reference to the drawings, the present invention is applicable to other aspects.

  For example, in the above-described embodiment, the shift positions are arranged in the order of the P position, the R position, the N position, the D position, and the B position from the front side to the rear side of the vehicle, but the order may be changed. A shift position corresponding to another traveling position may exist. Further, the shift lever 12 may be rotatable not only in the front-back direction of the vehicle but also in a different direction.

  In the above-described embodiment, the speed change operation device 10 is provided with the concave cushion member 44 on the intermediate surface 40 in the concave portion 30d corresponding to the D position, and the concave cushion member 44 on the intermediate surface 56 in the concave portion 30r corresponding to the R position. Although the member 46 is provided, it may be provided with only one of them. In order to suppress an erroneous operation, a concave cushion member 44 may be provided on an intermediate surface of the concave portion 30 corresponding to a shift position other than the D position, or a concave cushion member 44 corresponding to a shift position other than the R position may be provided. A convex cushion member 46 may be provided on the intermediate surface. That is, it is only necessary that the concave cushion member 44 and the convex cushion member 46 be provided on an intermediate surface that gives an operation resistance to a predetermined shift position in order to suppress an erroneous operation.

  Further, in the above-described embodiment, the moderation mechanism 20 has the uneven member 22 provided on the case 14 and the roller 26c provided on the shift lever 12, but the moderation mechanism has an uneven surface. It may have an uneven member provided on the shift lever 12 and a roller provided on the case 14 and constantly urged toward the uneven surface to come into contact with the uneven surface.

  Further, in the above-described embodiment, the concave cushion member 44 is inserted into the bottom 36 of the recess 30d and the intermediate surface 40 on both sides. However, the concave cushion member 44 may not be provided on the bottom 36 of the recess 30d. The concave cushion member 46 may be inserted only into the intermediate surface 40 on one side of the concave portion 30d. In this way, a large operation resistance can be applied only to a quick turning operation in one direction from a predetermined shift position.

  In the above-described embodiment, the concave cushion member 44 is an elastic member having a concave shape. However, for example, the concave cushion member 44 is dented only when it is inserted into only one intermediate surface 40 and a load is applied by the roller 26c. May be a flat elastic member.

  Further, in the above-described embodiment, the convex cushion members 46 are inserted into the intermediate surface 56 on one side of the concave portion 30r, but may be inserted one by one into the intermediate surface 56 on both sides of the concave portion 30r. .

  In the above-described embodiment, the convex cushion member 46 corresponding to the convex portion is an elastic member having a convex shape. However, the convex cushion member 46 may not be an elastic member. It may be something. Even in this case, since the spring 26a expands and contracts, when the shift lever 12 is rotated quickly, the roller 26c moves over the convex cushion member 46 as it is by the energy from the shift lever 12, so that the operation resistance is small, and the shift lever 12 Is rotated slowly, the energy from the shift lever 12 is small, and the driver needs to add a force to be applied to the shift lever 12, so that the operation resistance increases.

  In the above-described embodiment, the rod-shaped roller 26c is used as the rolling element, but a spherical steel ball may be used.

  It should be noted that the above is merely an embodiment, and that the present invention can be implemented in various modified and improved forms based on the knowledge of those skilled in the art.
