Description
Technical Field
The present invention relates to an operating device, and more particularly, to an operating lever that generates an operational feeling when operated.
Background
An operation device for switching the transmission is provided near a driver seat of the vehicle. For example, an operation device disclosed in patent document 1 includes a shift lever that rotates in two directions about two rotation axes. The operating device switches the transmission by transmitting an electric signal corresponding to the position of the shift lever to the vehicle. The shift lever of patent document 1 has a rod-like shape extending linearly, and includes a handle fixed to one end located outside a housing.
The operating device further includes a push rod movably attached to the other end of the shift lever in the housing. The push rod is urged in the extending direction of the shift lever by an elastic member in the shift lever, and is pressed against the concave-convex surface fixed in the housing. When the operator grips the knob and rotates the shift lever, the push rod moves along the concave-convex surface. The operator feels the operation feeling by the resistance between the push rod and the concave-convex surface. In either direction of the two rotational directions, one push rod presses a common continuous concave-convex surface to generate an operational feeling.

SUMMERY OF THE UTILITY MODEL
Problem to be solved by utility model
However, in the shift lever of patent document 1, since it is difficult to change the resistance force if the distance from the rotary shaft to the tip end of the push rod is short, a certain length is required from the rotary shaft to the tip end of the push rod along the extending direction of the shift lever. Further, when the distance from the rotation shaft to the tip end of the push rod is short, the moving distance of the tip end of the push rod becomes short, and the strength becomes weak though the size of the push rod needs to be reduced. Therefore, there is a disadvantage in that it is difficult to make the device thin in the extending direction of the shift lever.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an operation device which can maintain a large change in resistance and which has high strength and can be made thin.
Means for solving the problems
The utility model relates to an operating device, it possesses: an operation member that is rotatable about a first virtual rotation axis and a second virtual rotation axis upon operation by an operator; a first cam having a first concave-convex surface; a first guide member that rotates together with the operation member when the operation member rotates about the first virtual rotation axis; a first actuator movable in a first path defined by the first guide member; a first elastic member that urges the first actuator toward the first concave-convex surface; a second cam having a second concave-convex surface; a second guide member that rotates together with the operating member when the operating member rotates about the second virtual rotation axis; a second actuator movable in a second path defined by a second guide member; and a second elastic member that urges the second actuator toward the second concave-convex surface, wherein the operation member includes an operation shaft that extends in an axial direction substantially orthogonal to the first virtual rotation axis and the second virtual rotation axis, the first virtual rotation axis rotates about the second virtual rotation axis together with the operation member, and both the first path and the second path extend in a direction substantially orthogonal to the axial direction.
According to this configuration, since both the first path along which the first actuator moves and the second path along which the second actuator moves extend in the direction substantially orthogonal to the axial direction, the device can be made thinner in the axial direction as compared with a case where at least one of the first actuator and the second actuator moves in the axial direction. Further, even if the first actuator is made thick to increase the strength while the distance from the first virtual rotation axis to the tip of the first actuator is made long to maintain a large change in resistance, the operation device does not increase in the axial direction. That is, the resistance can be largely changed while the strength is high and the thickness is reduced.
Preferably, in the operation device of the present invention, the first virtual rotation axis and the second virtual rotation axis are substantially orthogonal to each other.
According to this configuration, in the operation device that rotates in two orthogonal directions, the operation device can be made thin and high in strength while maintaining a large change in resistance.
Preferably, in the operation device of the present invention, when the operation member is rotated about the first virtual rotation axis, the first path is substantially parallel to the second virtual rotation axis at one rotation position, and the first actuator is disposed on the second virtual rotation axis at one rotation position.
According to this configuration, when the operation member is rotated about the first virtual rotation axis, the first path is substantially parallel to the second virtual rotation axis at one rotation position, and the first actuator is disposed on the second virtual rotation axis at the one rotation position, so that when the operation member is rotated about the second virtual rotation axis while maintaining the one rotation position, the first actuator is rotated only in situ, and the relative position between the first actuator and the first cam is not largely changed. Therefore, the resistance generated by the first actuator does not greatly increase in resistance generated by the second actuator when the operating member is rotated about the second virtual rotation axis. Therefore, the resistance when the operation member is rotated about the second virtual rotation axis is easily controlled.
Preferably, in the operating device of the present invention, the first actuator has a rotationally symmetrical shape, and the center of symmetry of the first actuator substantially coincides with the second virtual rotation axis at one rotational position.
According to this configuration, since the first actuator has a rotationally symmetrical shape and the center of symmetry of the first actuator substantially coincides with the second virtual rotation axis at one rotational position, the relative position between the first actuator and the first cam can be kept constant when the operating member rotates about the second virtual rotation axis.
Preferably, in the operating device of the present invention, the first concave-convex surface has a first valley portion that is partially concave, and the first actuator is fitted in the first valley portion when the operating member is located at the first stable position around the first virtual rotation axis.
According to this configuration, since the first actuator is fitted in the first valley portion when the operating member is located at the first stable position around the first virtual rotation axis, it is possible to prevent the operating member from being accidentally rotated around the first virtual rotation axis when the operating member is rotated around the second virtual rotation axis.
Preferably, the operation device of the present invention further includes: an intermediate support body that supports the operation member so as to be rotatable about a first virtual rotation axis; and a support body that supports the intermediate support body so as to be rotatable about the second virtual rotation axis, wherein the first guide member is fixed to the operation member, and the second guide member is configured as a member integral with the intermediate support body.
According to this configuration, since the second guide member is formed as a member integrated with the intermediate support body, the number of components can be reduced as compared with the case of being separated.
Preferably, in the operating device of the present invention, the first cam is fixed to the support body.
According to this configuration, since the first cam is fixed to the support body, the area on the first concave-convex surface through which the first actuator passes when the operating member rotates about the first virtual rotation axis differs depending on the rotational position of the operating member about the second virtual rotation axis. Therefore, it is possible to provide the operator with various operating feelings as compared with the case where the first cam is fixed to the intermediate support body.
Preferably, in the operation device of the present invention, when the operation member is rotated about the second virtual rotation axis, the second path is substantially parallel to the first virtual rotation axis, and the second actuator is disposed on the first virtual rotation axis.
According to this configuration, when the operation member is rotated about the second virtual rotation axis, the second path is substantially parallel to the first virtual rotation axis, and the second actuator is disposed on the first virtual rotation axis, so that when the operation member is rotated about the first virtual rotation axis, the second actuator is rotated only in situ, and the relative position between the second actuator and the second cam does not change greatly. Therefore, the resistance force generated by the second actuator does not greatly increase in the resistance force generated by the first actuator when the operating member is rotated about the first virtual rotation axis. Therefore, the resistance when the operation member is rotated about the first virtual rotation axis is easily controlled.
Preferably, in the operation device of the present invention, the second actuator has a rotationally symmetrical shape, and a center of symmetry of the second actuator substantially coincides with the first virtual rotation axis.
According to this configuration, since the second actuator has a rotationally symmetrical shape and the center of symmetry of the second actuator substantially coincides with the first virtual rotation axis, the relative position of the second actuator and the second cam can be kept constant when the operating member rotates about the first virtual rotation axis.
Effect of the utility model
According to the present invention, there is provided an operation device capable of maintaining a large change in resistance while having high strength and thinning.

The third plate portion 141-3 connects the y 1-side end of the first plate portion 141-1 and the y 1-side end of the second plate portion 141-2 in the x direction. The fourth plate portion 141-4 connects the y 2-side end of the first plate portion 141-1 and the y 2-side end of the second plate portion 141-2 in the x direction. The fourth plate portion 141-4 is located closer to the y2 side than the third plate portion 141-3.
As shown in fig. 5, the intermediate support 140 further includes: a substantially cylindrical first shaft 142 (fig. 4) protruding in the x1 direction from the surface on the x1 side of the first plate portion 141-1; and a substantially cylindrical second shaft 143 (fig. 3) protruding in the x2 direction from the surface on the x2 side of the second plate portion 141-2.

As shown in fig. 8, the centers of the first intermediate bearing 144, the second intermediate bearing 145, and the third shaft 146 coincide with the first virtual rotation axis 101 parallel to the y direction. The y 1-side end of the third shaft 146 is fixed in the first intermediate bearing 144. The y 2-side end of the third shaft 146 is fixed in the second intermediate bearing 145.

(operating means)
As shown in fig. 3, the operating member 120 includes a base portion 121 and an operating shaft 122 extending from the base portion 121 in the z1 direction.
As shown in fig. 5, since the base portion 121 is sandwiched by the third plate portion 141-3 and the fourth plate portion 141-4 in the y direction, it does not move in the y direction. As shown in fig. 3, the base portion 121 is provided with a through-hole 123 having a substantially cylindrical shape and penetrating in the y direction. As shown in FIG. 8, a portion of the third shaft 146 is positioned within the through-shaft aperture 123. The diameter of the through-shaft hole 123 is substantially the same as the diameter of the third shaft 146. The center of the through-hole 123 coincides with the first virtual rotation axis 101. The intermediate support body 140 supports the operation member 120 via the third shaft 146 so as to be rotatable about the first virtual rotation axis 101.
The extending direction of the operation shaft 122 shown in fig. 3 is referred to as an axial direction, and the first virtual rotation shaft 101 shown in fig. 8 is substantially orthogonal to the second virtual rotation shaft 102. In the state shown in fig. 3, the axial direction substantially coincides with the z direction. However, the axial direction rotates around the first virtual rotation axis 101. The operation shaft 122 is substantially cylindrical in shape, and one end on the z2 side is fixed to the base 121. As shown in fig. 1, a part of the operation shaft 122 extends to the outside through the through hole 112-1 of the support body 110. The operating member 120 further includes a mounting protrusion 124 protruding in the z1 direction from the z 1-side end of the operating shaft 122. The mounting protrusion 124 is located outside the support body 110. A handle, not shown, is attached to the attachment projection 124 and is gripped by an operator.
As shown in fig. 8, the operating member 120 is rotatable about the first virtual rotation axis 101 in response to an operation by an operator, and is also rotatable about the second virtual rotation axis 102 together with the intermediate support 140. The first virtual rotation axis 101 is substantially orthogonal to the second virtual rotation axis 102 in the same plane. The first virtual rotation axis 101 rotates around the second virtual rotation axis 102 together with the operation member 120 in a state orthogonal to the axial direction of the operation shaft 122.
(first guide Member)
As shown in fig. 4, the first guide member 150 is formed integrally with the operating member 120 and is fixed to the operating member 120. The first guide member 150 protrudes from the x1 side of the base 121 of the operating member 120 in the x1 direction.
As shown in fig. 8, the first guide member 150 includes: a substantially cylindrical first outer hole 151 recessed from an x 1-side end portion in the x2 direction; and a substantially cylindrical first inner hole 152 recessed further in the x2 direction from the x 2-side end of the first outer hole 151. The respective centers of the first outer hole 151 and the first inner hole 152 coincide with the second virtual rotation axis 102 in the rotation position shown in fig. 8. The first inner bore 152 has a smaller diameter than the first outer bore 151. The first guide member 150 rotates together with the operating member 120 when the operating member 120 rotates about the first virtual rotation axis 101.
(second guide Member)
As shown in fig. 4, the second guide member 155 is formed as a member integral with the intermediate support body 140 and fixed to the intermediate support body 140. The second guide member 155 protrudes in the y1 direction from the surface of the third plate portion 141-3 of the intermediate support body 140 on the y1 side.
As shown in fig. 8, the second guide member 155 includes: a substantially cylindrical second outer hole 156 recessed from the y 1-side end in the y2 direction; and a second inner hole 157 of a substantially cylindrical shape, which is further recessed in the y2 direction from the y 2-side end of the second outer hole 156. The centers of the second outer hole 156 and the second inner hole 157 coincide with the first virtual rotation axis 101. The second inner bore 157 has a smaller diameter than the second outer bore 156. The second guide member 155 rotates together with the operating member 120 when the operating member 120 and the intermediate support 140 rotate about the second virtual rotation axis 102.
(first actuator)
As shown in fig. 3, the first actuator 160 includes a first large diameter portion 161, a first small diameter portion 162, and a first head 163. In the rotational position shown in fig. 8, each of the first large diameter portion 161 and the first small diameter portion 162 is substantially cylindrical having a central axis on the second virtual rotation axis 102. The x 1-side end of the first small diameter portion 162 is fixed to the x 2-side surface of the first large diameter portion 161. The first head 163 protrudes from the surface of the first large diameter portion 161 on the x1 side in the x1 direction. In the rotational position shown in fig. 8, the first head 163 has a substantially conical shape having a central axis on the second virtual rotational axis 102. The tip is located on the x1 side of the first header 163, and the tip is rounded.
As shown in fig. 8, first large diameter portion 161 is located within first outer bore 151. The first small diameter portion 162 is located within the first bore 152. In the rotated position shown in fig. 8, first large diameter portion 161 is slidable within first outer bore 151 and first small diameter portion 162 is slidable within first inner bore 152. The first actuator 160 is movable along a path defined by the first guide member 150 (hereinafter sometimes referred to as a first path). In one rotational position shown in fig. 8, the first path is substantially parallel to the second virtual rotational axis 102, and in the present embodiment coincides with the second virtual rotational axis 102.
As shown in fig. 8, the entire first actuator 160 is disposed on the second virtual rotation axis 102 at one rotation position when the operation member 120 rotates about the first virtual rotation axis 101, and has a rotationally symmetric shape around the second virtual rotation axis 102 at the same one rotation position.
(first elastic Member)
As shown in fig. 8, the first elastic member 169 is a metal coil spring wound around the first small diameter portion 162 of the first actuator 160. The first elastic member 169 is sandwiched in the x direction between a part of the first guide member 150 located on the x2 side within the first large diameter portion 161 and the first large diameter portion 161 located on the x1 side. The first elastic member 169 elastically urges the first actuator 160 toward the first concave-convex surface 132. In another example, the first elastic member 169 may be another elastic member such as rubber or a plate spring.
The vicinity of the x 1-side end of the first guide member 150 is partially located within the first groove 131 of the first cam 130. The x 1-side end of the first head 163 of the first actuator 160 contacts the first concave-convex surface 132 of the first cam 130.

As shown in fig. 3, the second actuator 170 includes a second large diameter portion 171, a second small diameter portion 172, and a second head 173. As shown in fig. 8, the second large diameter portion 171 and the second small diameter portion 172 are each substantially cylindrical in shape having a central axis on the first virtual rotation axis 101. A y 1-side end of the second small diameter portion 172 is fixed to the y 2-side surface of the second large diameter portion 171. The second head 173 protrudes from the y 1-side surface of the second large diameter portion 171 in the y1 direction.

The front end is located on the y1 side of the second head 173, and the front end is rounded.
As shown in fig. 8, the second large diameter portion 171 is located within the second outer bore 156. Second small diameter portion 172 is located within second bore 157. The second large diameter portion 171 is slidable along the first virtual rotation axis 101 in the second outer hole 156, and the second small diameter portion 172 is slidable along the first virtual rotation axis 101 in the second inner hole 157. The second actuator 170 is movable along a path defined by the second guide member 155 (hereinafter sometimes referred to as a second path). The second path is substantially parallel to the first virtual rotation axis 101, and in the present embodiment, coincides with the first virtual rotation axis 101.
As shown in fig. 8, the entire second actuator 170 is disposed on the first virtual rotation axis 101, and has a rotationally symmetric shape with respect to the first virtual rotation axis 101. Both the first path and the second path extend in a direction substantially orthogonal to the axial direction.
(second elastic Member)
As shown in fig. 8, the second elastic member 179 is a metal coil spring wound around the second small diameter portion 172 of the second actuator 170. The second elastic member 179 is sandwiched in the y direction between a part of the second guide member 155 on the y2 side within the second large diameter portion 171 and the second large diameter portion 171 on the y1 side. The second elastic member 179 elastically urges the second actuator 170 toward the second concave-convex surface 137. In other examples, the second elastic member 179 may be another elastic member such as rubber or a leaf spring.
The vicinity of the y 1-side end of the second guide member 155 is partially located in the second groove 136 of the second cam 135. The y 1-side end of the second head 173 of the second actuator 170 contacts the second concave-convex surface 137 of the second cam 135.
(action)
Fig. 1 to 8 are views of the operation device 100 at an initial position where the operation member 120 is not rotated in any direction. In the initial position, the operation device 100 is located at the first stable position in the initial state from the viewpoint of rotating about the first virtual rotation axis 101 shown in fig. 8. In the initial position, the operation device 100 is located at the second stable position in the initial state from the viewpoint of rotating about the second virtual rotation axis 102 shown in fig. 8.
The operation device 100 is rotatable about the first virtual rotation axis 101 shown in fig. 8 in the first rotation direction 181 and the second rotation direction 182 shown in fig. 6. The first rotational direction 181 is a direction in which the z 1-side end of the operating member 120 moves toward the x1 direction. The second rotational direction 182 is a direction in which the z 1-side end of the operating member 120 moves toward the x2 direction. Further, the operation device 100 can rotate in the third rotation direction 183 and the fourth rotation direction 184 shown in fig. 7 around the second virtual rotation axis 102 shown in fig. 8. The third rotational direction 183 is a direction in which the z 1-side end of the operating member 120 moves toward the y1 direction. The fourth rotational direction 184 is a direction in which the z 1-side end of the operating member 120 moves toward the y2 direction.
In the first stable position shown in fig. 6, the first path along which the first actuator 160 can move is substantially parallel to the second virtual rotation axis 102, and the center of rotational symmetry of the first actuator 160 substantially coincides with the second virtual rotation axis 102. When the operating member 120 is located at the first stable position shown in fig. 6, the x 1-side end of the first head 163 of the first actuator 160 is fitted in the first valley 133. Therefore, if the operation member 120 does not receive a certain degree of force, it does not rotate about the first virtual rotation axis 101 (fig. 8).
As shown in fig. 7, the second path that the second actuator 170 can move is substantially parallel to the first virtual rotation axis 101 regardless of the rotational position, and the center of rotational symmetry of the second actuator 170 is substantially coincident with the first virtual rotation axis 101 regardless of the rotational position. At the second stable position shown in fig. 7, the first virtual rotation axis 101 is substantially parallel to the y-direction. When the operating member 120 is located at the second stable position shown in fig. 7, the y 1-side end of the second head 173 of the second actuator 170 is fitted in the second valley 138. Therefore, if the operation member 120 does not receive a certain degree of force, it does not rotate about the second virtual rotation axis 102 (fig. 8).
Fig. 9 is a perspective view of the operation device 100 at a first rotational position where the operation member 120 shown in fig. 6 is rotated to some extent in the first rotational direction 181. Fig. 10 is a cross-sectional view of the operating device 100 with the operating member 120 in the first rotational position (fig. 9). Fig. 10 is a cross section in the same plane as fig. 6.
As shown in fig. 9, when the operating member 120 is rotated in the first rotational direction 181 (fig. 6), the second actuator 170 is retained and fitted in the second valley portion 138, as shown in fig. 7. Thus, as shown in fig. 9, intermediate support 140 does not rotate relative to support 110. As shown in fig. 10, the resistance generated when the first actuator 160 moves along the first concave-convex surface 132 is transmitted to the operator as the operation feeling. In the first rotational position shown in fig. 10, the first path of the first actuator 160 along the first guide member 150 is inclined with respect to the second virtual rotational axis 102.
Since the operation of the operating member 120 in the second rotational direction 182 shown in fig. 6 is symmetrical to the operation in the first rotational direction 181, the description thereof is omitted.
Fig. 11 is a perspective view of the operation device 100 at a second rotational position where the operation member 120 shown in fig. 7 is rotated to some extent in the third rotational direction 183. Fig. 12 is a sectional view of the operating device 100 when the operating member 120 is in the second rotational position (fig. 11). Fig. 12 shows a cross section in the same plane as fig. 7.
As shown in fig. 11, when the operating member 120 is rotated in the third rotational direction 183 (fig. 7), the first actuator 160 is fitted into the first valley portion 133, as shown in fig. 6. Therefore, as shown in fig. 11, the operating member 120 does not rotate relative to the intermediate support 140. As shown in fig. 12, the resistance generated when the second actuator 170 moves along the second concave-convex surface 137 is transmitted to the operator as the operation feeling. In the second rotational position shown in fig. 12, the second path of the second actuator 170 along the second guide member 155 is parallel to the first virtual rotational axis 101.
Since the operation of the operation member 120 in the fourth rotation direction 184 shown in fig. 7 is symmetrical to the operation in the third rotation direction 183, the description thereof is omitted.
(conclusion)
According to the present embodiment, since both the first path along which the first actuator 160 moves and the second path along which the second actuator 170 moves extend in the direction substantially orthogonal to the axial direction, the device can be made thinner in the axial direction as compared to the case where at least one of the first actuator 160 and the second actuator 170 moves in the axial direction. Further, even if the first actuator 160 is made thick to increase the strength while the distance from the first virtual rotation axis 101 to the tip of the first actuator 160 is made long to maintain a large change in resistance, the operation device 100 does not increase in the axial direction. That is, the resistance can be largely changed while the strength is high and the thickness is reduced.
According to the present embodiment, the operation device 100 that rotates in two orthogonal directions can be made thin and high in strength while maintaining a large change in resistance.
According to the present embodiment, when the operation member 120 is rotated about the first virtual rotation axis 101, the first path at one rotation position is substantially parallel to the second virtual rotation axis 102, and the first actuator 160 is disposed on the second virtual rotation axis 102 at the one rotation position, so that when the operation member 120 is rotated about the second virtual rotation axis 102 while maintaining the one rotation position, the first actuator 160 is rotated only in situ, and the relative position between the first actuator 160 and the first cam 130 does not change greatly. Therefore, the resistance generated by the first actuator 160 does not greatly increase in resistance generated by the second actuator 170 when the operating member 120 is rotated about the second virtual rotational axis 102. Therefore, the resistance when the operation member 120 rotates about the second virtual rotation axis 102 is easily controlled.
According to the present embodiment, since the first actuator 160 has a rotationally symmetrical shape and the center of symmetry of the first actuator 160 substantially coincides with the second virtual rotation axis 102 at one rotational position, the relative position between the first actuator 160 and the first cam 130 can be kept constant when the operating member 120 rotates around the second virtual rotation axis 102.
According to the present embodiment, since the first actuator 160 is fitted in the first valley portion 133 when the operating member 120 is located at the first stable position around the first virtual rotation axis 101, when the operating member 120 rotates around the second virtual rotation axis 102, it is possible to prevent the operating member 120 from rotating unintentionally around the first virtual rotation axis 101.
According to the present embodiment, since the second guide member 155 is formed as an integral member with the intermediate support body 140, the number of components can be reduced as compared with the case of being separate.
According to the present embodiment, since the first cam 130 is fixed to the support body 110, the area on the first concave-convex surface 132 through which the first actuator 160 passes when the operation member 120 rotates about the first virtual rotation axis 101 differs depending on the rotational position of the operation member 120 about the second virtual rotation axis 102. Therefore, it is possible to provide the operator with various operation feelings compared to the case where the first cam 130 is fixed to the intermediate support body 140.
In a modification, the second guide member 155 may be fixed to the operation member 120 without being fixed to the intermediate support body 140.
According to the modification, when the operation member 120 rotates about the second virtual rotation axis 102, the second path is substantially parallel to the first virtual rotation axis 101, and the second actuator 170 is disposed on the first virtual rotation axis 101, so that when the operation member 120 rotates about the first virtual rotation axis 101, the second actuator 170 rotates only in place, and the relative position between the second actuator 170 and the second cam 135 does not change greatly. Therefore, the resistance generated by the second actuator 170 does not greatly increase in resistance generated by the first actuator 160 when the operating member 120 rotates about the first virtual rotation axis 101. Therefore, the resistance when the operation member 120 rotates about the first virtual rotation axis 101 is easily controlled.
According to the modification, since the second actuator 170 has a rotationally symmetrical shape and the center of symmetry of the second actuator 170 substantially coincides with the first virtual rotation axis 101, the relative position of the second actuator 170 and the second cam 135 can be kept constant when the operation member 120 rotates about the first virtual rotation axis 101.
The first cam 130 may be fixed to the intermediate support 140. In this case, contrary to the above, the region on the first uneven surface 132 through which the first actuator 160 passes is constant regardless of the rotational position of the operation member 120 about the second virtual rotation axis 102, and therefore a constant operation feeling can be given to the operator. In addition, since the area on the first concave-convex surface 132 through which the first actuator 160 passes is limited, the size of the first cam 130 can be reduced.
The present invention is not limited to the above embodiment. That is, various modifications, combinations, sub-combinations, and substitutions may be made in the structural elements of the above embodiments by those skilled in the art within the technical scope of the present invention or equivalent thereof.
