Abstract
Description
[Technical Field]
[0001] The present invention relates to a steering device that can increase the space in front of a driver by changing the position of an operating member such as a steering wheel. [Background technology]
[0002] At autonomous driving level 3 or higher, where the system takes full responsibility for autonomous driving of a vehicle, the driver does not need to be responsible for operating the vehicle and does not need to hold the steering wheel. Therefore, if the steering wheel moves during autonomous driving and a larger space is secured in front of the driver, driver comfort can be improved. For this reason, technology has been proposed that moves the steering wheel to the front of the vehicle during autonomous driving (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] International Publication No. 2019 / 193956 Summary of the Invention [Problem to be solved by the invention]
[0004] However, if the operating member is 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 located near the engine compartment. Also, since the steering device is located facing downward toward the front of the vehicle, there is a possibility that it will interfere with vehicle components such as brake-related components and air conditioning-related components located below the steering device.
[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a steering device that can move operating members such as a steering wheel by a large amount while avoiding interference between the steering device and vehicle members. [Means for solving the problem]
[0006] In order to achieve the above-mentioned object, one aspect of the present invention is a steering device that holds an operating member so that it can be moved between a first position where the driver can steer and a second position on the front side of the vehicle, and includes a steering shaft that holds the operating member, a first movable member that rotatably holds the steering shaft, an intermediate guide member that holds the first movable member so that it can move back and forth along a first axis, and a base member that is fixed to the vehicle and holds the intermediate guide member so that it can move back and forth along a second axis, wherein the first axis extends in a downward direction as it approaches the front side of the vehicle, and the second axis extends in an upward direction relative to the first axis as it approaches the front side of the vehicle. [Effects of the Invention]
[0007] According to the present invention, it is possible to provide a steering device that can move an operating member by a large amount while avoiding a vehicle member. [Brief explanation of the drawings]
[0008] [Figure 1] FIG. 2 is a perspective view showing the steering device together with an operating member and a mounting portion. [Figure 2] FIG. 2 is an exploded perspective view of the steering device. [Figure 3] 1 is a side view showing a state in which the steering device is attached to a vehicle with an operating member advanced. FIG. [Figure 4] 10 is a side view showing a state in which the steering device is attached to the vehicle with the operating member retracted. FIG. DETAILED DESCRIPTION OF THE INVENTION
[0009] A steering device according to a first aspect of the present invention is a steering device that holds an operating member so that it can be moved between a first position where the driver can steer and a second position on the front side of the vehicle, and includes a steering shaft that holds the operating member, a first movable member that rotatably holds the steering shaft, an intermediate guide member that holds the first movable member so that it can move back and forth along a first axis, and a base member that is fixed to the vehicle and holds the intermediate guide member so that it can move back and forth along a second axis, wherein the first axis extends in a downward direction as it approaches the front side of the vehicle, and the second axis extends in an upward direction relative to the first axis as it approaches the front side of the vehicle.
[0010] This allows the entire steering device and operating member to move toward the front of the vehicle in the area above the first axis and reach the second position, thereby avoiding interference with other parts other than the steering device, such as vehicle components.
[0011] A steering device according to a second aspect of the present invention is similar to the steering device of the first aspect, in that the intermediate guide member includes a holding member that holds the first movable member so that it can move back and forth along a first axis, and a second movable member that is held by the base member so that it can move back and forth along the second axis and that holds the holding member so that it can tilt, and the base member holds the second movable member so that it can move back and forth along the second axis.
[0012] By configuring the intermediate guide member with a retaining member and a second movable member, relative movement between the second movable member and the retaining member can be realized, thereby improving the degree of freedom in positioning the operating member at the first position.
[0013] A steering device according to a third aspect of the present invention is the same as the steering device according to the first or second aspect, in which the second axis extends in an upward direction relative to the horizontal as it approaches the front of the vehicle.
[0014] This allows the steering device and the entire operating member, which have been moved to the second position, to be stored in a higher area facing the front of the vehicle than when they are in the first position, thereby ensuring even more space under the feet.
[0015] A steering device according to a fourth aspect of the present invention is, in addition to any one of the first, second, and third aspects, such that the foundation member comprises a 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 a 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 a 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 a second movable rail arranged on the other side of the first movable member and guided by the second base rail.
[0016] According to this, the intermediate guide member is guided with high support rigidity relative to the base member by the two rail mechanisms arranged on both sides in the width direction, and stable operation can be ensured.
[0017] Next, embodiments of a steering device according to the present invention will be described with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection configurations, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present invention. Furthermore, among the components in the following embodiments, components that are not described in the independent claims that represent the highest concept will be described as optional components.
[0018] Furthermore, the drawings are schematic diagrams in which emphasis, omission, and proportions have been appropriately adjusted in order to illustrate the present invention, and may differ from the actual shapes, positional relationships, and proportions.
[0019] In addition, in the following, multiple inventions may be collectively described as one embodiment, and some of the contents described below may be described as optional components related to the present invention.
[0020] FIG. 1 is a perspective view showing a steering device 100 together with an operating member 200 and a mounting portion 210. FIG. 2 is an exploded perspective view showing the steering device 100. The steering device 100 holds the operating member 200 so that it can move between an advanced position (first position) where the driver normally steers and a reverse position (second position) located in front of the vehicle 300 (X+ side in the figure). The steering device 100 includes a steering shaft 110, a first movable member 120, an intermediate guide member 103, and a base member 150. In this embodiment, the intermediate guide member 103 includes a holding member 130 and a second movable member 140. The steering device 100 is not mechanically connected to the steering mechanism of the vehicle 300 and is a device that realizes a so-called linkless steer-by-wire system that generates a signal based on the amount of operation of the operating member 200 by the driver and outputs the signal to a control device that controls the steering mechanism. The operating member 200 can also be steered while moving between the advanced position and the reverse position.
[0021] The operating member 200 is a member that is operated by the driver to steer the vehicle 300 (see FIGS. 3 and 4) to which the steering device 100 is attached. The shape of the operating member 200 is not particularly limited, and examples include a rod shape and a control stick shape. In the present embodiment, the operating member 200 is an annular member called a steering wheel. Note that although only the annular shape of the operating member 200 is shown in FIG. 1, the operating member 200 is provided with spokes for attachment to the steering shaft 110.
[0022] The mounting portion 210 is one or a portion of a vehicle member to which the steering device 100 is attached. In the present embodiment, the mounting portion 210 is a portion of a structural member that constitutes the vehicle body, such as a reinforcement. The reinforcement is, for example, a cylindrical beam that extends in the width direction of the vehicle 300.
[0023] The steering shaft 110 is attached to the first movable member 120 and is a member that rotatably holds the operating member 200. The shape of the steering shaft 110 is not particularly limited, and examples include a cylindrical shape and a hexagonal prism shape. The cross-sectional shape and cross-sectional area of the steering shaft 110 may change in the axial direction (X-axis direction in the figure). In the present embodiment, the steering shaft 110 is inserted coaxially inside the cylindrical first movable member 120 and attached to the first movable member 120 via a bearing.
[0024] A reaction force device 111 that generates a force counter to the force input by the driver to the operation member 200 is connected to the end of the steering shaft 110 on the front side of the vehicle 300. A steering angle sensor (not shown) that detects the amount of rotation of the steering shaft 110, a torque sensor (not shown) that detects the torque generated in the steering shaft 110, and the like are also connected to the steering shaft 110. A rotation amount limiting device 112 is connected to the end of the steering shaft 110 on the front side of the vehicle 300 (X+ side in the figure). The rotation amount limiting device 112 is a mechanism that limits the rotation angle of the steering shaft 110 within a predetermined range. In the case of a linkless steer-by-wire steering device 100, since there is no connection mechanism between the steering shaft 110 and the steered wheels that limits the rotation angle of the steering shaft 110, the reaction force device 111 is usually controlled by software to determine the rotation end of the operation member 200. However, in case that power is not supplied to the reaction force device 111, a rotation amount limiting device 112 is provided to mechanically limit the rotation of the operating member 200 within a predetermined angle range.
[0025] The first movable member 120 is a member that rotatably holds the steering shaft 110 and reciprocates along a first axis 221 relative to the intermediate guide member 103 together with the steering shaft 110 and the operating member 200 attached to the steering shaft 110. The shape of the first movable member 120 is not particularly limited, but in this embodiment, the first movable member 120 has a cylindrical shape that can penetrate the steering shaft 110, and is arranged so that its tube axis is along the first axis 221.
[0026] The intermediate guide member 103 is a member that holds the first movable member 120 so that the first movable member 120 can reciprocate along a first axis 221, and reciprocates along a second axis 222 relative to the base member 150. The shape and structure of the intermediate guide member 103 are not particularly limited. In this embodiment, the intermediate guide member 103 includes a holding member 130 and a second movable member 140.
[0027] The holding member 130 is a member that holds the first movable member 120 so that the first movable member 120 can reciprocate along the first axis 221, and is pivotally supported so that the first movable member 120 can tilt relative to the second movable member 140. The shape of the holding member 130 is not particularly limited. In the case of this embodiment, the holding member 130 includes a first holding member 131, a second holding member 132, and a link member 133.
[0028] First holding member 131 is a member that directly holds first movable member 120 so that it can reciprocate along first axis 221. The shape of first holding member 131 is not particularly limited as long as it is a shape that can guide first movable member 120. In the case of this embodiment, first holding member 131 has a cylindrical shape that extends along first axis 221, and is configured so that cylindrical first movable member 120 can be inserted into the inside.
[0029] A reaction force device 111 and a rotation amount restricting device 112 are attached to the end of the first holding member 131 on the front side of the vehicle 300 (X+ side in the figure). The steering shaft 110 connected to the reaction force device 111 and the rotation amount restricting device 112 is structured so as to expand and contract in accordance with the reciprocating movement of the first movable member 120 relative to the first holding member 131, and to be able to transmit torque received from the operating member 200. Examples of the structure of the steering shaft 110 include a telescopic structure with serration fitting and spline fitting.
[0030] Second holding member 132 is a member that is pivotally supported so as to be tiltable relative to second movable member 140, and that fixedly holds first holding member 131. With the above structure, second holding member 132 and first holding member 131 can be tilted relative to second movable member 140. When second holding member 132 and first holding member 131 are tilted, the angle of first axis 221, about which first movable member 120 reciprocates, relative to second axis 222 changes.
[0031] The shape of the second holding member 132 is not particularly limited. In the present embodiment, the second holding member 132 has a first shaft hole 134 at an end on the front side of the vehicle 300 (X+ side in the drawing) that is perpendicular to the first axis 221 and extends along a horizontal plane. The second holding member 132 is pivotally supported by a link member 133 at an end on the rear side of the vehicle 300 (X- side in the drawing). The rotation axis of the second holding member 132 relative to the link member 133 is parallel to the extension direction of the first shaft hole 134. The second holding member 132 has a top plate 135 and first wall portions 136 that hang down from both ends of the top plate 135 in the width direction of the vehicle 300 (Y-axis direction in the drawing), and the first holding member 131 is attached between the two first wall portions 136.
[0032] In the present embodiment, first moving means 161 is provided between second holding member 132 and first movable member 120 to reciprocate first movable member 120 relative to first holding member 131. The structure of first moving means 161 is not particularly limited. In the present embodiment, first moving means 161 includes a first lead screw 163 that extends along first axis 221 and moves together with first movable member 120 in the direction along first axis 221. In addition, first moving means 161 is fixed to second holding member 132 in the direction along first axis 221 and includes a first feed nut (not shown) that rotates around the rotation axis of first lead screw 163, and a first motor 164 that rotates the first feed nut.
[0033] The link member 133 is a member that transmits to the second holding member 132 a torque that tilts the second holding member 132 relative to the second movable member 140. The shape of the link member 133 is not particularly limited. In the present embodiment, the members that tilt integrally with the second movable member 140 are the first holding member 131, the second holding member 132, the first movable member 120, the steering shaft 110, and the operating member 200, and since these tilt about the first shaft hole 134, the link member 133 is shaped to withstand the generation of large torque. In addition, the link member 133 is shaped to suppress rattle in the tilting direction because force is applied to the operating member 200 by the driver. Specifically, the link member 133 includes two plate portions 165 arranged in an upright state along the two first wall portions 136 on the outer sides of the two first wall portions 136 of the second holding member 132, and a beam portion 166 connecting the two plate portions 165 below the first holding member 131. A first pivotal support portion 171 that pivotally supports the rear side of the vehicle 300 of the second holding member 132 is provided above the plate portion 165 on the rear side of the vehicle 300 (X- side in the figure), a second pivotal support portion 172 that pivotally supports the rear side of the vehicle 300 of the second movable member 140 is provided above the plate portion 165 on the front side of the vehicle 300 (X+ side in the figure), and a third pivotal support portion 173 that pivotally supports a tilting means 167, which will be described later, is provided below the plate portion 165.
[0034] The tilting means 167 is provided between the link member 133 and the second movable member 140, and is a device that tilts (rotates and swings) the second holding member 132 relative to the second movable member 140 via the link member 133. The structure of the tilting means 167 is not particularly limited. In the present embodiment, the tilting means 167 includes a tilting feed screw 174 that is rotatably supported by a third pivot support portion 173 of the link member 133. The tilting means 167 also includes a tilting feed nut 175 that is fixed to the second movable member 140 in the 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.
[0035] The second movable member 140 is held by the base member 150 so as to be reciprocatable along a second axis 222, holds the holding member 130 so as to be reciprocatable relative to the base member 150, and holds the holding member 130 so as to be tiltable relative to the second movable member 140. The shape of the second movable member 140 is not particularly limited. In the present embodiment, the second movable member 140 includes two second wall portions 142 that are arranged in a hanging state along the first wall portions 136 on the outer sides of the two first wall portions 136 of the second holding member 132, respectively, and a first connecting portion 141 that connects the two second wall portions 142 at the upper edges of the second wall portions 142. The second movable member 140 also includes a first movable rail 143 and a second movable rail 144 that are attached to the outer surfaces 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 in the width direction of the vehicle 300 so as to sandwich the first movable member 120 therebetween.
[0036] The base member 150 is a member fixed to the mounting portion 210, such as a reinforcement, which is one of the structural members of the vehicle 300, and holds the second movable member 140 of the intermediate guide member 103 so that it can move back and forth along the second axis 222. The base member 150 is fixed to the mounting portion 210 in a state where it holds the intermediate guide member 103 so that the first axis 221 extends downward as it approaches the front of the vehicle 300 (the X+ side in the figure). In the present embodiment, the base member 150 is fixed in a suspended state to the mounting portion 210 so that the second axis 222, which is the direction in which the intermediate guide member 103 moves, extends upward relative to the first axis 221 as it approaches the front of the vehicle 300. By attaching the base member 150 in this manner, the first axis 221 extends downward relative to the horizontal as it approaches the front of the vehicle 300. Note that, when the holding member 130 tilts relative to the second movable member 140, the first shaft 221 also tilts, but at any tilt position, the first shaft 221 maintains a state of extending downward relative to the second shaft 222 as it moves toward the front of the vehicle 300. In the case of this embodiment, at any tilt position, the first shaft 221 maintains a state of extending downward relative to the horizontal as it moves toward the front of the vehicle 300.
[0037] The shape of the foundation member 150 is not particularly limited. In this embodiment, the foundation 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 surfaces of the two third wall portions 151 along a 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 linear motion mechanism, and the second base rail 154 and the second movable rail 144 constitute a second linear motion mechanism. The first linear motion mechanism and the second linear motion mechanism are arranged to sandwich the first movable member 120 in the width direction of the vehicle 300.
[0038] The third wall portion 151 and the second connecting portion are integrally formed, and a bracket 190 is fixed to the second connecting portion. The base member 150 is fixed to the mounting portion 210 via the bracket 190 attached to the upper surface of the second connecting portion. The shape of the bracket 190 is not particularly limited, and a shape corresponding to the shape of the mounting portion 210 is selected.
[0039] In the present embodiment, second moving means 181 for reciprocating second movable member 140 relative to base member 150 is provided between base member 150 and second movable member 140 of intermediate guide member 103. The structure of second moving means 181 is not particularly limited. In the present embodiment, second moving means 181 includes a second feed screw 183 that extends in a direction along second axis 222 and moves together with second movable member 140 in the direction along second axis 222. Second moving means 181 also includes a second feed nut 182 that is fixed to base member 150 in the direction along second axis 222 and rotates around the rotation axis of second feed screw 183, and a second motor 184 that rotates second feed nut 182.
[0040] FIG. 3 is a side view showing the steering device 100 together with some of the vehicle components when the operation member 200 is disposed in the advanced position. FIG. 4 is a side view showing the steering device 100 together with some of the vehicle components when the operation member 200 is disposed in the reverse position. To advance the operation member 200 from the state shown in FIG. 4 to the state shown in FIG. 3, the intermediate guide member 103 is moved toward the rear of the vehicle 300 (X-side in the figure) while lowering relative to the mounting portion 210, and the first movable member 120 is moved toward the rear of the vehicle 300 (X-side in the figure) while raising relative to the intermediate guide member 103. In other words, the intermediate guide member 103 is moved toward the rear of the vehicle 300 while lowering along the second shaft 222, and the first movable member 120 is advanced along the first shaft 221 in an upward direction relative to the second shaft 222. By interlocking the movement of the first movable member 120 and the movement of the intermediate guide member 103 in this manner, the operation member 200 can be advanced in a predetermined axial direction, for example, along the front-to-rear direction of the vehicle 300 in a horizontal plane including the mounting portion 210, and the operation member 200 can be advanced while avoiding interference between vehicle members such as the brake-related member 310 and the intermediate guide member 103 and the first movable member 120. Note that the illustrated brake-related member 310 may be misaligned with the intermediate guide member 103 in the width direction of the vehicle 300 (the Y-axis direction in the figure). In this case, the brake-related member 310 and the intermediate guide member 103 do not interfere with each other.
[0041] 3 to the state shown in FIG. 4 , the first movable member 120 is moved toward the front of the vehicle 300 (X+ side in the figure) while lowering toward the intermediate guide member 103, and the intermediate guide member 103 is raised and moved toward the front of the vehicle 300 (X+ side in the figure) while approaching the attachment portion 210. That is, the first movable member 120 is moved toward the front of the vehicle 300 along the first axis 221 while being lowered, and the intermediate guide member 103 is moved toward the first axis 221 along the second axis 222 in an upward direction relative to the first axis 221. By interlocking the movement of the movable member 120 with the movement of the intermediate guide member 103 in this manner, the operation member 200 can be moved backward in a predetermined axial direction, for example, along the front-to-rear direction of the vehicle 300 in a horizontal plane including the attachment portion 210. This allows the operation member 200 to be moved toward the front of the vehicle 300 while avoiding interference between the intermediate guide member 103 and the first movable member 120 and vehicle components such as the brake-related member 310. 3 to the state shown in Fig. 4, even if the operation member 200 is moved toward the front of the vehicle 300 while being lowered, by moving the intermediate guide member 103 toward the mounting portion 210 while being raised toward the mounting portion 210, the operation member 200 as a whole moves toward the mounting portion 210, and interference between the operation member 200, the first movable member 120, and the intermediate guide member 103 and the vehicle members can be avoided. Furthermore, by arranging the mounting portion 210 at a relatively high position on the front side of the vehicle 300, it is possible to ensure a wide space not only in front of the driver but also under the driver's feet.
[0042] According to the steering device 100 of the embodiment, the first movable member 120 and the intermediate guide member 103 move backward toward the front of the vehicle in an area above the extension line of the first axis 221 in the advanced position, thereby making it possible to avoid interference with vehicle components when reversing.
[0043] Furthermore, by providing the intermediate guide member 103 with a retaining member 130 and a second movable member 140 and making the second movable member 140 tiltable relative to the retaining member 130, it is possible to improve the freedom of positioning of the operating member 200 in the advanced position while maintaining the effect of avoiding interference between the vehicle members and the steering device 100 when reversing.
[0044] Furthermore, by orienting the first shaft 221 downward and the second shaft 222 upward relative to the horizontal plane as the vehicle approaches the front, the first movable member 120 and the intermediate guide member 103 can be pulled up and moved backward toward the front of the vehicle, thereby ensuring ample space not only in front of the driver but also at the driver's feet.
[0045] Furthermore, the intermediate guide member 103 is held reciprocally relative to the base member 150 by a first movable rail 143 and a first base rail 153 (first linear motion mechanism) and a second movable rail 144 and a second base rail 154 (second linear motion mechanism), which are arranged on either side of the first movable member 120 and the holding member 130 in the width direction of the vehicle and extend in the second axial direction. In other words, since no linear motion mechanism is arranged above the intermediate guide member 103, the intermediate guide member 103 can be pulled up as close as possible to the mounting portion 210. This increases the space under the driver's feet when the operating member 200 is in the reverse position. Furthermore, the first linear motion mechanism and the second linear motion mechanism can support the intermediate guide member 103 and the first movable member 120 in a balanced manner, thereby increasing the support rigidity.
[0046] The present invention is not limited to the above-described embodiments. For example, the present invention may be embodied in another embodiment by arbitrarily combining the components described in this specification or by excluding some of the components. Furthermore, the present invention also includes various modifications that would occur to a person skilled in the art without departing from the spirit of the present invention, i.e., the meaning of the wording of the claims.
[0047] For example, although the case where the base member 150 is fixed to the mounting portion 210 in a state where it is suspended from a vehicle member such as a reinforcement has been described, the base member 150 may also be attached in a state where it is placed on the vehicle member.
[0048] Furthermore, although the steering device 100 has been described as including a tilt mechanism that tilts the moving direction (first axis 221) of the first movable member 120, the steering device 100 may not necessarily include a tilt mechanism.
[0049] Furthermore, the guide mechanism for the second movable member 140 relative to the base member 150 has been described as two rail mechanisms, and the guide mechanism for the first movable member 120 relative to the first holding member 131 has been described as two tubular members that slide in an interlocking state, but the types and combinations of guide mechanisms are not limited to these, and any type or combination may be adopted.
[0050] Furthermore, although the linear motion mechanisms are disposed on both sides of the intermediate guide member 103 in the width direction of the vehicle in the above description, this does not mean that a linear motion mechanism may be disposed above the intermediate guide member 103 . [Industrial Applicability]
[0051] The present invention can be used in a steer-by-wire type steering device for steering a vehicle 300 such as an automobile, a bus, or a truck. [Explanation of symbols]
