Description

Technical Field

[0001] The present invention relates to a steering device capable of expanding a space in front of a driver by changing the position of an operating member such as a steering wheel. Background Art

[0002] In the case of an automatic driving of a vehicle, in a state of automatic driving level 3 or above where the system is fully responsible, the driver does not need to be responsible for the operation of the vehicle and does not need to hold the steering wheel. Therefore, during automatic driving, if the steering wheel is moved to ensure a larger space in front of the driver, the driver's comfort can be improved. Therefore, a technology for moving the steering wheel toward the front of the vehicle during automatic driving has been proposed (for example, refer to Patent Document 1).

[0003] Patent Document 1: International Publication No. 2019 / 193956

[0004] However, if the operating member is to be moved as far forward as possible, the overall length of the steering device will be increased, and the front end of the steering device will be arranged near the engine room. In addition, the steering device is arranged to face the front and downward of the vehicle, so there is a possibility of interference with vehicle components such as brake-related components and air conditioning equipment-related components arranged below the steering device. Summary of the invention

[0005] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a steering device that can avoid interference between the steering device and vehicle components and can largely move operating components such as a steering wheel.

[0006] In order to achieve the above-mentioned purpose, a steering device as one of the present invention is a steering device that holds an operating member in a manner that allows it to move between a first position at which a driver can perform steering operation and a second position on the front side of a vehicle, and comprises: a steering shaft that holds the operating member; a first movable member that holds the steering shaft in a rotatable manner; an intermediate guide member that holds the first movable member in a manner that allows it to reciprocate along a first axis; and a base member that is fixed to the vehicle and holds the intermediate guide member in a manner that allows it to reciprocate along a second axis, the first axis extending in a downward direction as it moves toward the front side of the vehicle, and the second axis extending in an upward direction relative to the first axis as it moves toward the front side of the vehicle.

[0007] According to the present invention, it is possible to provide a steering device that can avoid vehicle components and can largely move an operating member. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] A steering device according to a first embodiment of the present invention holds an operating member in a manner that allows it to move between a first position at which a driver can perform steering operation and a second position at the front side of a vehicle, the steering device comprising: a steering shaft that holds the operating member; a first movable member that holds the steering shaft in a rotatable manner; an intermediate guide member that holds the first movable member in a manner that allows it to reciprocate along a first axis; and a base member that is fixed to the vehicle and holds the intermediate guide member in a manner that allows it to reciprocate along a second axis, the first axis extending in a downward direction as it moves toward the front side of the vehicle, and the second axis extending in an upward direction relative to the first axis as it moves toward the front side of the vehicle.

[0013] As a result, the entire region of the steering device and the operating member above the first axis moves toward the vehicle front side and reaches the second position, so interference with vehicle components and other components other than the steering device can be avoided.

[0014] In addition to the above-mentioned first embodiment, the steering device of the second embodiment of the present invention is characterized in that the above-mentioned intermediate guide component includes: a holding component, which holds the above-mentioned first movable component in a manner that allows it to reciprocate along the first axis; and a second movable component, which is held by the above-mentioned base component in a manner that allows it to reciprocate along the above-mentioned second axis, and the above-mentioned holding component is held so as to be tiltable, and the above-mentioned base component holds the above-mentioned second movable component in a manner that allows it to reciprocate along the second axis.

[0015] Since the intermediate guide member is composed of the holding member and the second movable member, relative movement between the second movable member and the holding member can be realized, and the degree of freedom in arrangement of the operating member at the first position can be increased.

[0016] In a steering device according to a third embodiment of the present invention, in addition to the first embodiment or the second embodiment, the second shaft extends in an upward direction relative to a horizontal direction as it moves toward the front side of the vehicle.

[0017] Thus, the entire steering device and the operating member moved to the second position are accommodated toward the vehicle front side in a region above that in the first position, so that a larger foot space can be ensured.

[0018] In addition to any one of the first, second and third embodiments, the steering device of the fourth embodiment of the present invention comprises: the first base rail arranged on one side of the first movable member in the width direction of the vehicle and extending along the second axis; and the second base rail arranged on the other side of the first movable member and extending along the second axis, and the intermediate guide member comprises: the first movable rail arranged on one side of the first movable member in the width direction of the vehicle and guided by the first base rail; and the second movable rail arranged on the other side of the first movable member and guided by the second base rail.

[0019] Thus, the two rail mechanisms disposed on both sides in the width direction can guide the intermediate guide member with high support rigidity with respect to the base member, thereby ensuring stable operation.

[0020] Next, the embodiments of the steering device of the present invention are described with reference to the accompanying drawings. In addition, the embodiments described below all represent general or specific examples. The numerical values, shapes, materials, structural members, configuration positions of structural members, connection forms, steps, order of steps, etc. shown in the following embodiments are examples and do not limit the purpose of the present invention. In addition, the structural members in the following embodiments that are not recorded in the independent technical solutions representing the highest-level concepts are described as arbitrary structural members.

[0021] In addition, the drawings are schematic diagrams in which emphasis, omission, and ratio adjustment are appropriately performed in order to illustrate the present invention, and may differ from actual shapes, positional relationships, and ratios.

[0022] In addition, a plurality of inventions may be collectively described as one embodiment below. In addition, a part of the contents described below is described as an arbitrary structural member related to the present invention.

[0023] Figure 1 It is a perspective view showing the operating member 200 , the mounting portion 210 , and the steering device 100 . Figure 21 is a perspective view showing the steering device 100 in an exploded manner. The steering device 100 is a steering device 100 that holds the operating member 200 in a manner that allows it to move between the position where the driver normally steers, i.e., the forward position (first position) and the front side (in the figure, the X+ side) of the vehicle 300, i.e., the reverse position (second position), and includes a steering shaft 110, a first movable member 120, an intermediate guide member 103, and a base member 150. In the case of the present embodiment, the intermediate guide member 103 includes a holding member 130 and a second movable member 140. The steering device 100 is a device that realizes so-called unlinked electric steering, which generates a signal based on the amount of operation of the operating member 200 by the driver without being mechanically connected to the steering mechanism of the vehicle 300, and outputs the signal to a control device that controls the steering mechanism. In addition, the operating member 200 can also be steered in the middle of moving between the forward position and the reverse position.

[0024] The operating member 200 is used by the driver to control the vehicle 300 (see Figure 3 , Figure 4 ) is a component that is operated to perform steering. The shape of the operating component 200 is not particularly limited, and examples thereof include a rod shape, a joystick shape, etc. In the case of this embodiment, the operating component 200 is a ring-shaped component called a steering wheel. Figure 1 In FIG. 1 , the operating member 200 is depicted as only a ring, but the operating member 200 includes spokes and the like for being mounted on the steering shaft body 110 .

[0025] The mounting portion 210 is one of the vehicle components or a portion to which the steering device 100 is mounted. In the present embodiment, the mounting portion 210 is a portion of a structural member constituting the vehicle body such as a reinforcement. The reinforcement is, for example, a cylindrical beam extending in the width direction of the vehicle 300.

[0026] The steering shaft 110 is a component that is mounted on the first movable member 12 and holds the operating member 200 in a rotatable manner. The shape of the steering shaft 110 is not particularly limited, and examples thereof include a cylindrical shape, a hexagonal prism shape, etc. In addition, the cross-sectional shape and cross-sectional area of ​​the steering shaft 110 may also change in the axial direction (in the figure, the X-axis direction). In the case of this embodiment, the steering shaft 110 is coaxially inserted into the inner side of the cylindrical first movable member 120 and is mounted on the first movable member 120 via a bearing.

[0027] In addition, a reaction force device 111 is connected to the end of the steering shaft body 110 on the front side of the vehicle 300, which causes the operating member 200 to generate a force opposite to the force input by the driver. In addition, a rotation angle sensor (not shown) for detecting the rotation amount of the steering shaft body 110, a torque sensor (not shown) for detecting the torque generated by the steering shaft body 110, etc. are connected to the steering shaft body 110. In addition, a rotation amount limiting device 112 is connected to the end of the steering shaft body 110 on the front side of the vehicle 300 (in the figure, the X+ side). The rotation amount limiting device 112 is a mechanism that limits the rotation angle of the steering shaft body 110 within a specified range. In the case of a steering device 100 without a linkage electric steering, there is no connection mechanism between the steering shaft body 110 and the steering wheel, so the rotation end of the operating member 200 is usually determined by software by controlling the reaction force device 111. However, since power is not supplied to the reaction force device 111, for example, a rotation amount limiting device 112 is provided to mechanically limit the rotation of the operation member 200 within a predetermined angle range.

[0028] The first movable member 120 is a member that rotatably holds the steering shaft body 110 and reciprocates along the first axis 221 relative to the intermediate guide member 103 together with the steering shaft body 110 and the operating member 200 attached to the steering shaft body 110. The shape of the first movable member 120 is not particularly limited, but in the present embodiment, the first movable member 120 is in the shape of a cylinder that can pass through the steering shaft body 110, and is arranged with the tube axis along the first axis 221.

[0029] The intermediate guide member 103 is a member that holds the first movable member 120 so as to be reciprocatable along the first axis 221 and reciprocates along the second axis 222 relative to the base member 150. The shape and structure of the intermediate guide member 103 are not particularly limited. In the present embodiment, the intermediate guide member 103 includes a holding member 130 and a second movable member 140.

[0030] The holding member 130 is a member that holds the first movable member 120 in a manner that allows reciprocating movement along the first axis 221, and is axially supported to be tiltable relative to the second movable member 140. The shape of the holding member 130 is not particularly limited. In the present embodiment, the holding member 130 includes a first holding member 131, a second holding member 132, and a connecting member 133.

[0031] The first holding member 131 is a member that directly holds the first movable member 120 in a manner that allows reciprocating movement along the first shaft 221. The shape of the first holding member 131 is not particularly limited as long as it can guide the first movable member 120. In the case of this embodiment, the first holding member 131 is a cylindrical shape extending along the first shaft 221, and the cylindrical first movable member 120 can be passed through the inside.

[0032] A reaction force device 111 and a rotation amount limiting device 112 are mounted on the end of the first holding member 131 on the front side of the vehicle 300 (in the figure, the X+ side). The steering shaft body 110 connected to the reaction force device 111 and the rotation amount limiting device 112 is a structure that can be extended and retracted according to the reciprocating movement of the first movable member 120 relative to the first holding member 131, and can transmit the torque received from the operating member 200. The structure of the steering shaft body 110 can be exemplified by a telescopic structure of a serration fitting or a spline fitting.

[0033] The second holding member 132 is a member that is pivotally supported on the second movable member 140 in a tiltable manner and fixedly holds the first holding member 131. According to the above structure, the second holding member 132 and the first holding member 131 can be tilted relative to the second movable member 140. When the second holding member 132 and the first holding member 131 are tilted, the angle of the first axis 221 of the reciprocating movement of the first movable member 120 relative to the second axis 222 changes.

[0034] The shape of the second holding member 132 is not particularly limited. In the case of the present embodiment, the second holding member 132 is provided with a first axial hole 134 for pivotally supporting the second movable member 140 at an end portion on the front side of the vehicle 300 (X+ side in the figure) in a manner orthogonal to the first axis 221 and along a horizontal plane. The second holding member 132 is pivotally supported by the connecting member 133 at an end portion on the rear side of the vehicle 300 (X- side in the figure). The rotation axis of the second holding member 132 relative to the connecting member 133 is parallel to the extension direction of the first axial hole 134. The second holding member 132 is provided with a top plate 135 and first wall portions 136 hanging down at both ends of the top plate 135 in the width direction of the vehicle 300 (Y-axis direction in the figure), and the first holding member 131 is installed between the two first wall portions 136.

[0035] In the case of the present embodiment, a first moving mechanism 161 is provided between the second holding member 132 and the first movable member 120 for reciprocating the first movable member 120 relative to the first holding member 131. The structure of the first moving mechanism 161 is not particularly limited. In the case of the present embodiment, the first moving mechanism 161 includes a first feed screw 163 extending along the first axis 221 and moving together with the first movable member 120 in the direction along the first axis 221. In addition, the first moving mechanism 161 includes a first feed nut (not shown) fixed to the second holding member 132 in the direction along the first axis 221 and rotating around the rotation axis of the first feed screw 163; and a first motor 164 that rotates the first feed nut.

[0036] The connecting member 133 is a member that transmits the torque that tilts the second holding member 132 relative to the second movable member 140 to the second holding member 132. The shape of the connecting member 133 is not particularly limited. In the case of this embodiment, the members that tilt integrally relative to the second movable member 140 are the first holding member 131, the second holding member 132, the first movable member 120, the steering shaft body 110, and the operating member 200, which tilt around the first shaft hole 134, so the shape of the connecting member 133 is a shape that can withstand the occurrence of a large torque. In addition, since the driver applies a force to the operating member 200, the shape of the connecting member 133 is a shape that suppresses the generation of a gap in the tilting direction. Specifically, the connecting member 133 includes two plate portions 165 arranged in an upright state along the first wall portion 136 on the outer side of each of the two first wall portions 136 of the second holding member 132, and a beam portion 166 that connects the two plate portions 165 below the first holding member 131. A first axis support portion 171 on the rear side of the vehicle 300 for axially supporting the second retaining member 132 is provided on the upper side of the plate portion 165 and on the rear side of the vehicle 300 (the X- side in the figure), a second axis support portion 172 on the rear side of the vehicle 300 for axially supporting the second movable member 140 is provided on the upper side of the plate portion 165 and on the front side of the vehicle 300 (the X+ side in the figure), and a third axis support portion 173 on the lower side of the plate portion 165 for axially supporting a tilting mechanism 167 described later is provided.

[0037] The tilting mechanism 167 is a device that is disposed between the connecting member 133 and the second movable member 140, and that causes the second retaining member 132 to tilt (rotate and swing) relative to the second movable member 140 via the connecting member 133. The structure of the tilting mechanism 167 is not particularly limited. In the case of the present embodiment, the tilting mechanism 167 includes a tilting feed screw 174 that is rotatably supported by a third axis support portion 173 of the connecting member 133. In addition, the tilting mechanism 167 includes: a tilting feed nut 175 that is fixed to the second movable member 140 in a direction along the first axis 221 and rotates around the rotation axis of the tilting feed screw 174; and a tilting motor 176 that rotates the tilting feed nut 175.

[0038] The second movable member 140 is a member that is held by the base member 150 in a manner that allows reciprocation along the second axis 222, holds the holding member 130 in a manner that allows reciprocation relative to the base member 150, and holds the holding member 130 in a manner that allows tilting relative to the second movable member 140. The shape of the second movable member 140 is not particularly limited. In the case of this embodiment, the second movable member 140 includes: two second wall portions 142 that are arranged in a hanging state along the first wall portion 136 on the outer side of each of the two first wall portions 136 of the second holding member 132; and a first connecting portion 141 that connects the two second wall portions 142 at the upper edge of the second wall portion 142. In addition, the second movable member 140 includes a first movable rail 143 and a second movable rail 144 that are attached to the outer side surfaces of each of the two second wall portions 142 along the second axis 222 in the width direction of the vehicle 300. The first movable rail 143 and the second movable rail 144 are arranged so as to sandwich the first movable member 120 in the width direction of the vehicle 300 .

[0039] The base member 150 is a member fixed to the mounting portion 210 such as a reinforcement member as one of the structural members of the vehicle 300, and holds the second movable member 140 of the intermediate guide member 103 so as to be reciprocatingly movable along the second axis 222. The base member 150 is fixed to the mounting portion 210 in a state of holding the intermediate guide member 103 so as to extend in a downward direction as the first axis 221 moves toward the front side of the vehicle 300 (in the figure, the X+ side). In the case of the present embodiment, the base member 150 is fixed to the mounting portion 210 in a suspended state so as to extend in an upward direction relative to the first axis 221 as the second axis 222 moves toward the front side of the vehicle 300, which is the direction in which the intermediate guide member 103 moves. By mounting the base member 150 in this way, the first axis 221 extends in a downward direction relative to the horizontal axis as it moves toward the front side of the vehicle 300. Furthermore, as the holding member 130 tilts relative to the second movable member 140, the first shaft 221 also tilts, but at any tilting position, the first shaft 221 is maintained in a state of extending in a downward direction relative to the second shaft 222 as it moves toward the front side of the vehicle 300. In the case of the present embodiment, at any tilting position, the first shaft 221 is maintained in a state of extending in a downward direction relative to the horizontal as it moves toward the front side of the vehicle 300.

[0040] The shape of the base member 150 is not particularly limited. In the present embodiment, the base member 150 includes: two third wall portions 151 arranged in a hanging state along the second wall portions 142 on the outer sides of the two second wall portions 142 of the second movable member 140; a second connecting portion (not shown) connecting the two third wall portions 151 at the upper edges of the third wall portions 151; and a first base rail 153 and a second base rail 154 attached to the inner side surfaces of the two third wall portions 151 along the second axis 222 in the width direction of the vehicle 300 and guiding the first movable rail 143 and the second movable rail 144, respectively. The first base rail 153 and the first movable rail 143 constitute a first direct motion mechanism, and the second base rail 154 and the second movable rail 144 constitute a second direct motion mechanism. The first direct motion mechanism and the second direct motion mechanism are arranged to sandwich the first movable member 120 in the width direction of the vehicle 300.

[0041] The third wall portion 151 is integrally formed with the second connection portion, and the bracket 190 is fixed to the second connection portion. The base member 150 is fixed to the mounting portion 210 via the bracket 190 mounted on the upper surface of the second connection portion. The shape of the bracket 190 is not particularly limited, and a shape corresponding to the shape of the mounting portion 210 can be selected.

[0042] In the case of the present embodiment, a second moving mechanism 181 for reciprocating the second movable member 140 relative to the base member 150 is provided between the base member 150 and the second movable member 140 of the intermediate guide member 103. The structure of the second moving mechanism 181 is not particularly limited. In the case of the present embodiment, the second moving mechanism 181 includes: a second feed screw 183 extending in the direction of the second axis 222 and moving together with the second movable member 140 in the direction of the second axis 222. In addition, the second moving mechanism 181 includes: a second feed nut 182 fixed to the base member 150 in the direction of the second axis 222 and rotating around the rotation axis of the second feed screw 183; and a second motor 184 for rotating the second feed nut 182.

[0043] Figure 3 It is a side view showing the steering device 100 together with some vehicle components in a state where the operating member 200 is arranged in the forward position. Figure 4 1 is a side view of the steering device 100 showing a state where the operating member 200 is arranged in the rearward position together with a part of the vehicle components. Figure 4 The status shown is Figure 3 In the state shown, in order to advance the operating member 200, the intermediate guide member 103 is moved toward the rear side (X-side in the figure) of the vehicle 300 while being lowered relative to the mounting portion 210, and the first movable member 120 is moved toward the rear side (X-side in the figure) of the vehicle 300 while being raised relative to the intermediate guide member 103. That is, the intermediate guide member 103 is moved toward the rear side of the vehicle 300 while being lowered along the second axis 222, and the first movable member 120 is advanced in the upward direction relative to the second axis 222 along the first axis 221. In this way, by interlocking the movement of the first movable member 120 with the movement of the intermediate guide member 103, the operating member 200 can be advanced along a predetermined uniaxial direction, for example, the front-rear direction of the vehicle 300 in a horizontal plane including the mounting portion 210, and the interference between the vehicle components such as the brake-related component 310 and the intermediate guide member 103 and the first movable member 120 can be avoided, and the operating member 200 can be advanced. In addition, the brake-related component 310 shown in the figure may be offset from the intermediate guide member 103 in the width direction (in the figure, the Y-axis direction) of the vehicle 300. In this case, the brake-related component 310 and the intermediate guide member 103 do not interfere with each other.

[0044] In addition, from Figure 3 The status shown is Figure 4In the state shown, in order to move the operating member 200 backward, the first movable member 120 is moved toward the front side (X+ side in the figure) of the vehicle 300 while being lowered toward the intermediate guide member 103, and the intermediate guide member 103 is moved toward the front side (X+ side in the figure) of the vehicle 300 while being lifted and approaching the mounting portion 210. That is, the first movable member 120 is moved while being lowered toward the front side of the vehicle 300 along the first axis 221, and the intermediate guide member 103 is moved backward in the upward direction relative to the first axis 221 along the second axis 222. In this way, by linking the movement of the movable member 120 with the movement of the intermediate guide member 103, the operating member 200 can be moved backward along a predetermined axial direction, for example, the front-rear direction of the vehicle 300 in the horizontal plane including the mounting portion 210, and the interference between the vehicle components such as the brake-related component 310, the intermediate guide member 103 and the first movable member 120 can be avoided, and the operating member 200 can be moved to the front side of the vehicle 300. Figure 3 The status shown is Figure 4 When the operating member 200 is moved backward in the state shown, even if the operating member 200 is moved to the front side of the vehicle 300 while being lowered, the operating member 200 as a whole can be moved toward the mounting portion 210 by raising the intermediate guide member 103 toward the mounting portion 210 while being moved to the front side of the vehicle 300, thereby avoiding interference between the operating member 200, the first movable member 120, and the intermediate guide member 103 and vehicle components. In addition, by arranging the mounting portion 210 at a relatively high position on the front side of the vehicle 300, not only the front space of the driver can be expanded, but also a larger foot space for the driver can be ensured.

[0045] According to the steering device 100 of the embodiment, the first movable member 120 and the intermediate guide member 103 move backward toward the vehicle front side in the region above the extension line of the first shaft 221 in the forward position, so that interference with vehicle components during backward movement can be avoided.

[0046] In addition, the intermediate guide member 103 includes a retaining member 130 and a second movable member 140, which can tilt the second movable member 140 relative to the retaining member 130, thereby maintaining the effect of avoiding interference between the vehicle components and the steering device 100 during reverse movement and increasing the degree of freedom in configuring the operating member 200 in the forward position.

[0047] In addition, by moving the first axis 221 downward relative to the horizontal plane and the second axis 222 upward as the vehicle 300 moves forward, the first movable component 120 and the intermediate guide component 103 can be pulled up while retreating toward the front of the vehicle, thereby not only expanding the space in front of the driver but also ensuring a larger space for the driver's feet.

[0048] In addition, the intermediate guide member 103 can be held in a reciprocating manner relative to the base member 150 by the first movable rail 143 and the first base rail 153 (first direct motion mechanism) and the second movable rail 144 and the second base rail 154 (second direct motion mechanism) respectively arranged in the width direction of the vehicle so as to sandwich the first movable member 120 and the holding member 130, that is, no direct motion mechanism is arranged on the upper side of the intermediate guide member 103, so that the intermediate guide member 103 can be lifted as close to the mounting portion 210 as possible. As a result, the foot space of the driver in the state where the operating member 200 is arranged in the retreat position can be expanded. In addition, the intermediate guide member 103 and the first movable member 120 can be supported in a well-balanced manner by the first direct motion mechanism and the second direct motion mechanism, so that the support rigidity can be improved.

[0049] In addition, the present invention is not limited to the above-mentioned embodiments. For example, the structural components described in this specification may be arbitrarily combined, and other embodiments realized by removing some of the structural components may be used as embodiments of the present invention. In addition, the present invention also includes the modified examples obtained by implementing various modifications that can be thought of by those skilled in the art relative to the above-mentioned embodiments without departing from the purpose of the present invention, that is, the meaning of the text indicated in the technical solution.

[0050] For example, although the case where the base member 150 is fixed to the mounting portion 210 in a state of being hung on a vehicle component such as a reinforcement has been described, the base member 150 may be mounted on the vehicle component in a placed state.

[0051] Furthermore, the steering device 100 has been described as including a tilt mechanism that tilts along the moving direction (first axis 221) of the first movable member 120. However, the tilt mechanism may not be included.

[0052] In addition, although the description is given of the guide mechanism of the second movable part 140 relative to the base part 150 being set as two rail mechanisms, and the two tube parts that slide the first movable part 120 relative to the guide mechanism of the first retaining part 131 in an interlocking state, the type and combination of the guide mechanism are not limited to this, and any type and combination may be used.

[0053] Furthermore, although the case where the direct-acting mechanisms are disposed on both sides of the intermediate guide member 103 in the width direction of the vehicle has been described, the case where the direct-acting mechanism is disposed on the upper side of the intermediate guide member 103 is not ruled out.

[0054] Possibility of industrial application

[0055] The present invention can be applied to an electric steering type steering device for steering a vehicle 300 such as an automobile, a bus, or a truck.
