Description

[Technical field]

[0001] The present disclosure relates to a steering device. [Background technology]

[0002] Patent Document 1 discloses a steering wheel having a function of detecting whether or not it is being gripped by an occupant. The steering wheel of Patent Document 1 includes a rim portion that is gripped by an occupant and rotated. The rim portion has a substantially circular shape when viewed from the occupant's side. A soft covering portion made of polyurethane foam is disposed around a core metal that is a portion that forms a skeleton of the rim portion. A skin made of three layers each made of a different material is disposed around the soft covering portion. A soft layer made of polyurethane foam is disposed as the outermost layer of the skin. A base fabric made of fibers is disposed as the middle layer of the skin. A conductive layer made of a conductive material is disposed as the innermost layer of the skin. The conductive layer is a coating film formed by applying a conductive paint to the inside of the base fabric. The conductive layer imparts conductivity to the entire skin and functions as an electrode. When an occupant grips the rim portion, the capacitance between the skin and the occupant changes with respect to the capacitance when the rim portion is not gripped. The detection board detects the gripping state of the rim portion based on the changed capacitance. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-165940 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the steering wheel of Patent Document 1, a conductive layer is disposed over the entire circumference of a substantially annular rim portion. In the conductive layer, the potential may differ between a portion connected to a power source and a portion far from the portion connected to the power source. In addition, the conductive layer is not ideally configured uniformly over the entire surface. Therefore, in the steering wheel of Patent Document 1, the detection accuracy of the grip may vary depending on the portion gripped by the occupant. [Means for solving the problem]

[0005] The present disclosure can be realized in the following forms.

[0006] (1) According to one embodiment of the present disclosure, there is provided a steering device, the steering device being provided on a moving body, comprising: a rotating part rotatably attached to the moving body; and a grip part connected to the rotating part, the grip part comprising a core metal part configured symmetrically with respect to the rotating part; and a covering part covering at least a part of the core metal part, the covering part comprising: a first conductive part disposed on one side of a symmetry plane of the core metal part, the first conductive part being made of a conductive material; and a second conductive part disposed on the other side of the symmetry plane of the core metal part, the second conductive part being made of a conductive material, the first conductive part and the second conductive part being independent of each other, the steering device further comprising: a harness electrically connecting the first conductive part and the second conductive part; and a detector electrically connected to the first conductive part and the second conductive part via the harness, the detector detecting a gripping state of the grip part based on a change in electrostatic capacitance occurring in at least one of the first conductive part and the second conductive part. In this steering device, the first conductive part and the second conductive part are located on different sides of the symmetry plane and are independent of each other. Therefore, the area of ​​each conductive part is smaller than in a case where one conductive part covers the entire outer circumference of the core metal part. As a result, it is possible to reduce the variation in detection accuracy caused by the difference in the parts gripped by the first conductive part and the second conductive part. (2) In the steering device of the above form, the grip portion is a portion gripped by an occupant, and when the portion of the surface of the core metal portion facing the occupant is defined as the surface portion and the portion opposite the surface portion is defined as the back portion, the first conductive portion may include a first front conductive portion arranged in contact with the surface portion and a first rear conductive portion arranged in contact with the back portion, the second conductive portion may include a second front conductive portion arranged in contact with the surface portion and a second rear conductive portion arranged in contact with the back portion, and the harness may include a first harness electrically connecting the first front conductive portion and the second front conductive portion, and a second harness electrically connecting the first rear conductive portion and the second rear conductive portion. (3) In a steering device of the above form, the core metal portion has an annular outer shape, and when the rotating part is in a standard angular position, the uppermost part, which is the uppermost part in the vertical direction of the core metal portion, is located vertically above the rotating part, and the covering part may be arranged from a part of the core metal portion that is upper with respect to the center of rotation of the rotating part and does not include the uppermost part, to the lowermost part, which is the lowermost part in the vertical direction of the core metal portion. With this form of steering device, compared to a form in which the first conductive portion and the second conductive portion are each arranged from the top to the bottom of the core metal portion, it is possible to reduce variation in detection accuracy resulting from differences in the portions that are gripped for each of the first conductive portion and the second conductive portion. The detection of whether the steering device is being gripped is performed in order to detect whether the occupant of the moving body is in a state where the occupant can operate the moving body. On the other hand, if the occupant is gripping the uppermost part of the gripping part, which is located at the uppermost part in the vertical direction, there is a possibility that the occupant will not be able to instantly operate the steering device in the intended direction by the intended amount. Therefore, there is little need to detect that the steering device is being gripped when the uppermost part of the core metal part is being gripped. (4) In the steering device of the above form, the grip portion is a portion that is gripped by an occupant, the portion of the surface of the core metal portion that faces the occupant is a surface portion, and the portion opposite the surface portion is a back portion, the core metal portion has a ring-shaped outer shape, the grip portion further includes one or more light source bodies that are arranged vertically above the rotating part when the rotating part is in a reference angle position and on the surface portion of the core metal portion, and are configured to be able to emit light depending on the situation of the moving body, and the covering portion may be arranged on a portion of the core metal portion other than where the light source body is arranged. According to the steering device of this aspect, the grip portion can include the light source body and the covering portion. The present disclosure may be realized in various forms, for example, in the form of a vehicle equipped with a steering device, a manufacturing method for a steering device, and the like.

[0008] A. First embodiment: FIG. 1 is an explanatory diagram showing a vehicle VW provided with a steering device 1 of a first embodiment. In FIG. 1, the steering device 1 is shown in a simplified form. In FIG. 1, an X-axis, a Y-axis, and a Z-axis that are perpendicular to each other are shown. The X-axis is the left-right direction of the vehicle VW. The direction from the front to the back of the paper of FIG. 1 is the positive direction of the X-axis. The Y-axis is a direction parallel to the direction in which a rotation axis AR described later extends. The Z-axis is a direction perpendicular to the X-axis and the Y-axis. This is the same in FIG. 2 to FIG. 5, FIG. 8 to FIG. 10 described later. In FIG. 1, the vertical direction is represented by the VU-axis. The vertical upward direction is the positive direction of the VU-axis.

[0009] FIG. 2 is a view of the steering device 1 of FIG. 1 viewed in the +Y direction. In FIG. 2, the steering device 1 is shown in a simplified form. FIG. 3 is a view of the steering device 1 shown in FIG. 2 with the cover 25 omitted. The cover 25 will be described later. The steering device 1 shown in FIG. 1 is a device that realizes steering of the vehicle VW by being operated by a driver DR who is an occupant of the vehicle VW. The steering device 1 is connected to a rotating shaft AR protruding from inside the front part FRO of the vehicle VW (see the rotating shaft AR in FIG. 1). The steering device 1 is attached to the vehicle VW via the rotating shaft AR. As shown in FIG. 2 and FIG. 3, the steering device 1 includes a rotating part 10, a grip part 20, a harness 30, and a detector 40. Note that the rotating shaft AR shown in FIG. 1 is omitted in FIG. 2 and FIG. 3. The same applies to FIG. 4, FIG. 9, and FIG. 10.

[0010] The rotating unit 10 is rotatably attached to the vehicle VW. Specifically, the rotating unit 10 is rotatably attached to the vehicle VW by passing the rotating shaft AR shown in FIG. 1 through and fixing it to a hole 101 formed in the rotating unit 10. The rotating unit 10 shown in FIG. 2 is connected to the gripping unit 20. In this embodiment, when the rotating unit 10 is not rotated, the rotating unit 10 is symmetrical with respect to a plane including the Y axis and the Z axis. The position of the rotating unit 10 where the symmetrical plane of the rotating unit 10 includes the Y axis and the Z axis is defined as the "reference angular position of the rotating unit 10". The fact that the rotating unit 10 is located at the reference angular position of the rotating unit 10 is expressed as "the rotating unit 10 is at the reference angular position". FIG. 2 shows a state in which the rotating unit 10 is at the reference angular position. The same applies to FIGS. 3 to 5, 9, and 10.

[0011] 4 is a diagram of the steering device 1 shown in FIG. 3 with the first covering portion 22 and the rotating portion 10 omitted. Note that in FIG. 4, for convenience, a hole 101 formed in the rotating portion 10 is shown. The first covering portion 22 will be described later. The grip portion 20 is a portion that is gripped by a driver DR who is an occupant of the vehicle VW. As shown in FIGS. 2 to 4, the grip portion 20 includes a core metal portion 21, a first covering portion 22, and a skin 25.

[0012] The core metal portion 21 shown in Fig. 4 is a portion covered with a first covering portion 22 and a skin 25 (see Figs. 2 and 3). As shown in Figs. 2 to 4, in this embodiment, the core metal portion 21 is configured symmetrically with respect to the rotating portion 10. In this embodiment, the core metal portion 21 is configured symmetrically with respect to a first plane of symmetry PS1, which is a plane including the Y-axis and Z-axis, when the rotating portion 10 is in a reference angular position.

[0013] FIG. 5 is a view of the steering device 1 shown in FIG. 4 viewed toward the +X direction. In FIG. 5, the VU axis is shown. In this embodiment, the core metal part 21 is configured symmetrically with respect to the second symmetry plane PS2, which is a plane including the X axis and the Z axis, when the rotating part 10 is in a reference angular position. As shown in FIG. 5, the second symmetry plane PS2 is a plane passing through the center of the core metal part 21 in the Y direction when the core metal part 21 is viewed in the X axis direction. In this embodiment, the part of the surface of the core metal part 21 facing the occupant is the front part 21A, and the part opposite the front part 21A is the back part 21B. Specifically, the part of the surface of the core metal part 21 facing the occupant and on one side of the second symmetry plane PS2 as shown in FIG. 1 and FIG. 5 is the front part 21A. Also, as shown in FIG. 1 and FIG. 5, the part of the surface of the core metal part 21 on the other side of the second symmetry plane PS2 is the back part 21B.

[0014] As shown in FIG. 3 and FIG. 5, in this embodiment, when the rotating part 10 is in a reference angular position, the uppermost part 21a, which is the uppermost part in the vertical direction of the core metal part 21, is located vertically above the rotating part 10. Also, when the rotating part 10 is in a reference angular position, the lowermost part 21b, which is the lowermost part in the vertical direction of the core metal part 21, is located vertically below the rotating part 10. In this specification, "vertically above the rotating part 10" means a range above the range occupied by the rotating part 10 in the vertical direction. When an object A is "vertically above the rotating part 10", it does not mean that it is directly above the rotating part 10 in the vertical direction. In other words, when projected in the vertical direction, the horizontal position of the object A does not have to overlap with the rotating part 10. Similarly, in this specification, "vertically below the rotating part 10" means a range below the range occupied by the rotating part 10 in the vertical direction. The fact that an object A is "vertically below the rotating part 10" does not mean that the object A is directly below the rotating part 10 in the vertical direction. In other words, when projected in the vertical direction, the horizontal position of the object A does not have to overlap with the rotating part 10. As shown in FIG. 4, in this embodiment, the core metal part 21 has an annular outer shape when viewed in the Y direction. The core metal part 21 includes a core metal 210 and a soft covering part 211.

[0015] The core metal 210 is a part that forms the skeleton of the core metal part 21. The core metal 210 is covered with a soft covering part 211. As shown in FIG. 2 to FIG. 4, the core metal 210 is configured symmetrically with respect to the rotating part 10. In this embodiment, the core metal 210 has an annular outer shape when viewed in the Y direction. The core metal 210 is formed of an alloy such as iron, aluminum, or magnesium. The core metal 210 is connected to a fixing member that is a member disposed on the inner circumference of the core metal 210 and extends in the X-axis direction. The fixing member is not shown. The fixing member is formed of the same material as the core metal 210. The fixing member has a hole to which the above-mentioned rotating shaft AR is connected when viewed in the Y-axis direction. The soft covering part 211 protects the core metal 210 by covering the core metal 210. In this embodiment, the soft covering part 211 is formed of foamed polyurethane.

[0016] FIG. 6 is a diagram showing the first covering portion 22 and the harness 30 in a state where the core metal portion 21 is not covered. FIG. 7 is a schematic diagram of FIG. 6. In FIG. 7, a detector 40 is shown for ease of understanding. The first covering portion 22 functions as an electrode together with the skin 25. In this embodiment, as shown in FIG. 3, the first covering portion 22 is arranged along the outer periphery and inner periphery of the core metal portion 21 when viewed in the Y-axis direction.

The first detection portion 220 is disposed on the outer surface of the core metal portion 21 so that one end 220a of the first detection portion 220 shown in FIG. 6 contacts the uppermost portion 21a of the core metal portion 21 as shown in FIG. 3. The first detection portion 220 is disposed on the outer surface of the core metal portion 21 so that the other end 220b of the first detection portion 220 shown in FIG. 6 contacts the lowermost portion 21b of the core metal portion 21 as shown in FIG. 3. As shown in FIG. 6, when the first detection portion 220 does not cover the core metal portion 21, the first detection portion 220 has a substantially rectangular outer shape. As shown in FIG. 7, the first detection portion 220 includes a first conductive portion 221, a first shield portion 222, a first insulating portion 223, a first conductive terminal 224, and a first shield terminal 225.

As shown in FIG. 8, the first shield part 222 and the first insulating part 223 are disposed between the first conductive part 221 and the core metal part 21. In this specification, the first conductive part 221 being disposed on the outer surface of the core metal part 21 includes not only the case where the first conductive part 221 is directly disposed on the outer surface of the core metal part 21, but also the case where at least one of the first shield part 222 and the first insulating part 223 is disposed between the core metal part 21 and the first conductive part 221. The same applies to the second conductive part 231 described later. As shown in FIG. 3, the first conductive part 221 is disposed on one side, that is, the +X direction side, with respect to the first symmetry plane PS1 of the core metal part 21.

[0019] The first conductive portion 221 is formed of a conductive material. In this embodiment, the first conductive portion 221 is a coating film formed by applying a conductive paint to the first insulating portion 223. As the conductive paint, a paint resin mixed with conductive carbon or metal oxide powder can be used. As shown in Figs. 7 and 8, the first conductive portion 221 includes a first front conductive portion 221a and a first rear conductive portion 221b.

[0020] As shown in FIG. 8, the first front conductive part 221a is arranged in contact with the surface part 21A of the core metal part 21 on the side facing the occupant. In this specification, the first front conductive part 221a is arranged in contact with the surface part 21A of the core metal part 21, including not only the case where the first front conductive part 221a is directly in contact with the surface part 21A, but also the case where at least one of the first shield part 222 and the first insulating part 223 is arranged between the first front conductive part 221a and the surface part 21A. Specifically, as shown in FIG. 8, the first front conductive part 221a is arranged on the −Y direction side, which is one side with respect to the second symmetry plane PS2 of the core metal part 21. As shown in FIG. 3, the first front conductive part 221a is arranged from the periphery of the uppermost part 21a to the periphery of the lowermost part 21b of the core metal part 21. As shown in FIG. 8, the first rear conductive part 221b is arranged in contact with the back part 21B of the core metal part 21 on the opposite side to the surface part 21A. In this specification, the term "the first rear conductive portion 221b is arranged in contact with the back surface portion 21B of the core metal portion 21" includes not only the case where the first rear conductive portion 221b is in direct contact with the back surface portion 21B, but also the case where at least one of the first shield portion 222 and the first insulating portion 223 is arranged between the first rear conductive portion 221b and the back surface portion 21B. Specifically, the first rear conductive portion 221b is arranged on the +Y direction side, which is the other side with respect to the second plane of symmetry PS2 of the core metal portion 21. The first rear conductive portion 221b is arranged from the periphery of the uppermost portion 21a to the periphery of the lowermost portion 21b of the core metal portion 21. In this embodiment, the length of the first rear conductive portion 221b along the outer periphery of the core metal portion 21 is the same as the length of the first front conductive portion 221a.

[0021] The first shielding part 222 shown in FIG. 7 and FIG. 8 has a function of blocking the electrostatic capacitance between the core metal 210 and the first conductive part 221.

As shown in FIG. 8, the first shielding part 222 is arranged on the surface of the first insulating part 223 opposite to the surface on which the first conductive part 221 is arranged. The shape of the first insulating part 223 will be described later. The first shielding part 222 is formed by applying paint containing a material having electrical conductivity to the first insulating part 223. By arranging the first shielding part 222 between the core metal 210 and the first conductive part 221, the detection of the grip of the grip part 20 using the first conductive part 221 is stably performed.

[0022] The first insulating part 223 insulates the first conductive part 221 from the first shield part 222. The first insulating part 223 is disposed between the first conductive part 221 and the first shield part 222.

That is, the harness 30 electrically connects the first conductive portion 221 and the second conductive portion 231 via the first conductive terminal 224 and the second conductive terminal 234. In this embodiment, the harness 30 includes a first harness 310 and a second harness 320. The first harness 310 electrically connects the first front conductive portion 221a and the second front conductive portion 231a. The first harness 310 has one end connected to the first front leading terminal 224a, the second front leading terminal 234a, the first front shield terminal 225a, and the second front shield terminal 235a, and the other end connected to the detector 40. The second harness 320 electrically connects the first rear conductive portion 221b and the second rear conductive portion 231b. The second harness 320 has one end connected to the first rear leading terminal 224b, the second rear leading terminal 234b, the first rear shield terminal 225b, and the second rear shield terminal 235b, and the other end connected to the detector 40.

[0032] The detector 40 detects the gripping state of the grip portion 20 based on a change in electrostatic capacitance occurring in at least one of the first conductive portion 221 and the second conductive portion 231. The detector 40 is electrically connected to the first conductive portion 221 and the second conductive portion 231 via the harness 30. As shown in FIG. 3, the detector 40 is disposed between the hole 101 formed in the rotating portion 10 and the lowermost portion 21b of the core metal portion 21. By disposing the detector 40 at this position, the appearance of the steering device 1 is improved compared to, for example, a mode in which the detector 40 is disposed between the rotating portion 10 and the uppermost portion 21a of the core metal portion 21. In this embodiment, as shown in FIG. 7, the detector 40 includes a first detector 410 and a second detector 420. Note that, although only the detector 40 is shown in FIG. 3, the first detector 410 and the second detector 420 are disposed between the hole 101 formed in the rotating portion 10 and the lowermost portion 21b of the core metal portion 21. 7, the first detector 410 is electrically connected to the first front conductive part 221a, the second front conductive part 231a, the first front shield terminal 225a, and the second front shield terminal 235a via the first harness 310. Although not shown, the first detector 410 includes various circuits including an oscillation circuit, a resonance circuit, a detection circuit, and an amplifier circuit.

[0033] When the grip portion 20 is gripped by the occupant, the capacitance between the occupant and at least one of the first front conductive portion 221a and the second front conductive portion 231a changes from the capacitance when the grip portion 20 is not gripped, and the resonance frequency changes. The first detector 410 amplitude-modulates the changed resonance frequency, detects it in a detection circuit, amplifies the signal in an amplifier circuit, and outputs it as a voltage to an ECU (Electronic Control Unit) (not shown) of the vehicle VW. The ECU detects the grip state of the grip portion 20 based on whether the voltage value is greater than a preset threshold value. The voltage of the first shield portion 222 and the second shield portion 232 detected by the first detector 410 is used to accurately output a voltage based on the capacitance between the occupant and the first front conductive portion 221a or the second front conductive portion 231a. Second detector 420 is electrically connected to first rear conductive part 221b, second rear conductive part 231b, first rear shield terminal 225b, and second rear shield terminal 235b via second harness 320. The configuration of second detector 420 is the same as that of first detector 410.

[0034] In the steering device 1 of this embodiment, the first conductive portion 221 and the second conductive portion 231 are located on different sides of the first symmetry plane PS1 and are independent of each other. Therefore, the area of ​​each conductive portion is smaller than in a mode in which one conductive portion covers the entire outer periphery of the core metal portion 21. As a result, it is possible to reduce variation in detection accuracy caused by differences in the portions of the first conductive portion 221 and the second conductive portion 231 that are gripped.

[0035] The steering device 1 further includes a harness 30 that electrically connects the first conductive part 221 and the second conductive part 231, and the detector 40 is electrically connected to the first conductive part 221 and the second conductive part 231 via the harness 30. For example, compared to an embodiment in which a terminal that electrically connects the first conductive part 221 and the detector 40 and a terminal that electrically connects the second conductive part 231 and the detector 40 are not connected by the harness 30, a decrease in work efficiency is less likely to occur when arranging the first covering part 22 on the core metal part 21 during manufacturing of the steering device 1. In this embodiment, a first harness 310 that electrically connects the first front conductive part 221a and the second front conductive part 231a, and a second harness 320 that electrically connects the first rear conductive part 221b and the second rear conductive part 231b are provided. For example, compared to an embodiment not including the first harness 310 and the second harness 320, when manufacturing the steering device 1, a decrease in work efficiency is less likely to occur when arranging the first covering portion 22 on the core metal portion 21.

[0036] In this specification, when the first conductive part 221 is disposed on one side with respect to the plane of symmetry of the core metal part 21 and the second conductive part 231 is disposed on the other side, this means that the first conductive part 221 is disposed on one side with respect to the first plane of symmetry PS1, which is the plane of symmetry of the core metal part 21 configured symmetrically with respect to the rotating part 10, and the second conductive part 231 is disposed on the other side. In other words, the "plane of symmetry" in the above description does not include the second plane of symmetry PS2.

[0037] B. Second embodiment: Fig. 9 is a schematic diagram of a steering device 1B of a second embodiment. Fig. 9 corresponds to Fig. 2. The second embodiment differs from the first embodiment in that the grip portion 20 includes a first light source body 51 and a second light source body 52, that the second covering portion 22B covers the core metal portion 21 instead of the first covering portion 22, and that the shape of the skin 25B is different. The other configurations of the second embodiment are similar to those of the first embodiment, so the same reference numerals are used and detailed description will be omitted.

[0038] The first light source body 51 and the second light source body 52 are configured to be able to emit light according to the situation of the vehicle VW. The first light source body 51 and the second light source body 52 of this embodiment are turned on to encourage the driver DR to grip the grip part 20. When the rotating part 10 is in a reference angular position, the first light source body 51 and the second light source body 52 are arranged on the outer surface of the core metal part 21 on the vertical upper side with respect to the rotating part 10. In this embodiment, the first light source body 51 and the second light source body 52 are arranged side by side in the X direction, sandwiching the uppermost part 21a of the core metal part 21. In addition, the first light source body 51 and the second light source body 52 are arranged on the surface part 21A of the core metal part 21 on the side facing the occupant. In this embodiment, the first light source body 51 and the second light source body 52 are LEDs. The first light source body 51 and the second light source body 52 are electrically connected to the ECU of the vehicle VW, and receive a signal from the ECU to emit light.

[0039] FIG. 10 is a diagram illustrating the second covering portion 22B. FIG. 11 is a diagram illustrating the second covering portion 22B in a state where the core metal portion 21 is not covered. The second covering portion 22B has a configuration similar to that of the first covering portion 22. The second covering portion 22B has a first detection portion 220B and a second detection portion 230B. The following describes the differences from the first covering portion 22. The second covering portion 22B is disposed in a portion of the core metal portion 21 other than the portion where the first light source body 51 and the second light source body 52 are disposed. The second covering portion 22B differs from the first covering portion 22 in the shapes of the first pre-conductive portion 221Ba and the second pre-conductive portion 231Ba.

[0040] As shown in Fig. 11, in the first front conductive portion 221Ba of the second covering portion 22B, the end portion 221Baa on the side closer to the uppermost portion 21a with respect to the lowermost portion 21b of the core portion 21 in Fig. 10 is closer to the lowermost portion 21b than the end portion 221Bba of the first rear conductive portion 221Bb. In other words, when viewed in a state in which the second covering portion 22B covers the core portion 21, the length of the first front conductive portion 221Ba of the second covering portion 22B along the outer periphery of the core portion 21 is smaller than the length of the first rear conductive portion 221Bb of the second covering portion 22B (see Figs. 10 and 11). Note that, as shown in Fig. 11, the first shield portion 222B and the first insulating portion 223B are configured to have a length corresponding to the length of the first front conductive portion 221Ba along the outer periphery of the core portion 21. 10, there is a portion of the surface of core metal portion 21 that is not covered by first front conductive portion 221a on surface portion 21A facing the occupant and vertically above rotating portion 10. This portion is where first light source body 51 shown in FIG 9 is disposed. The length along the outer periphery of core metal portion 21 of first rear conductive portion 221Bb of second covering portion 22B is the same as the length along the outer periphery of core metal portion 21 of first rear conductive portion 221b of first covering portion 22 shown in FIG 3.

[0041] Similarly, in the second front conductive portion 231Ba of the second covering portion 22B, an end portion 231Baa on the side closer to the uppermost portion 21a relative to the lowermost portion 21b of the core portion 21 is closer to the lowermost portion 21b than an end portion 231Bba of the second rear conductive portion 231Bb. In other words, when viewed in a state in which the second covering portion 22B is disposed on the core portion 21, the length of the second front conductive portion 231Ba of the second covering portion 22B along the outer periphery of the core portion 21 is smaller than the length of the second rear conductive portion 231Bb of the second covering portion 22B. Note that, as shown in FIG. 11, the second shield portion 232B and the second insulating portion 233B are configured to have a length corresponding to the length of the second front conductive portion 231Ba along the outer periphery of the core portion 21. As a result, as shown in Fig. 10, of the surface of the core metal portion 21, there is a portion that is not covered by the first front conductive portion 221a on surface portion 21A facing the occupant and vertically above the rotating portion 10. This portion is the portion where the second light source body 52 shown in Fig. 9 is disposed. The length of the second rear conductive portion 231Bb of the second covering portion 22B along the outer periphery of the core metal portion 21 is the same as the length of the second rear conductive portion 231b of the first covering portion 22 along the outer periphery of the core metal portion 21.

[0042] In this embodiment, when the rotating part 10 is at a reference rotation angle and the steering device 1 is viewed in the +Y direction, the angle range A1 between the first detection part 220B and the second detection part 230B is configured to be about 50° on a plane including the X-axis and the Z-axis, centered on the center of the hole 101 formed in the rotating part 10. Note that the angle shown in FIG. 10 is not accurate.

[0043] As shown in FIG. 9, the skin 25B of the second embodiment is configured to cover the core metal portion 21 and the second covering portion 22B, but not to cover the first light source body 51 and the second light source body 52.

[0044] In the steering device 1B of the second embodiment, the grip portion 20 includes a first light source body 51, a second light source body 52, and a second covering portion 22B. By including the first light source body 51 and the second light source body 52 in the grip portion 20, light according to the situation of the moving object is emitted, thereby improving the convenience of the steering device 1B.

[0045] C. Third embodiment: FIG. 12 is a diagram for explaining the third covering portion 22C of the third embodiment. As shown in FIG. 12, the third embodiment differs from the first embodiment in that the steering device 1C includes a third covering portion 22C instead of the first covering portion 22. Since the other configurations are the same as those of the first embodiment, the same reference numerals are used and detailed description is omitted. The third covering portion 22C includes the same configuration as the first covering portion 22. That is, the third covering portion 22C includes a first detection portion 220C and a second detection portion 230C. The differences from the first covering portion 22 will be described below.

[0046] Although not shown, the third covering portion 22C is disposed from a portion of the core metal portion 21 that is an upper side with respect to the center of rotation of the rotating portion 10 and does not include the uppermost portion 21a to the lowermost portion 21b of the core metal portion 21. In detail, the third covering portion 22C is configured so that the angle range A1 between the first detecting portion 220C and the second detecting portion 230C centered on the center of the hole 101 formed in the rotating portion 10 is about 50°, similar to the second embodiment shown in FIG. 9 and FIG. 10. Furthermore, in the third embodiment, although not shown, when the steering device 1C is viewed in the −Y direction, the angle range between the first detecting portion 220C and the second detecting portion 230C centered on the center of the hole 101 formed in the rotating portion 10 is configured to be about 50°. As a result, the third covering portion 22C is disposed from a portion of the core metal portion 21 that is an upper side with respect to the center of rotation of the rotating portion 10 and does not include the uppermost portion 21a to the lowermost portion 21b of the core metal portion 21. In other words, the first conductive portion 221C and the second conductive portion 231C are arranged from the portion of the core metal portion 21 that is above the center of rotation of the rotating portion 10 and does not include the top portion 21a to the bottom portion 21b of the core metal portion 21.

[0047] A dimension D1 from one end to the other end of the first detection portion 220C shown in Fig. 12 is smaller than a dimension D2 from one end to the other end of the first detection portion 220 of the first covering portion 22 shown in Fig. 7. The same is true for the second detection portion 230C of the third covering portion 22C.

[0048] In the third embodiment, compared to the embodiment in which the first conductive part 221C and the second conductive part 231C are arranged from the uppermost part 21a to the lowermost part 21b of the core metal part 21, the variation in detection accuracy due to the difference in the parts gripped for each of the first conductive part 221C and the second conductive part 231C can be reduced. The detection of the grip of the steering device 1C is performed to detect that the occupant of the moving body is in a state in which the occupant can operate the moving body. On the other hand, when the occupant grips the part of the grip part 20 located on the upper side in the vertical direction with respect to the rotation axis AR, the occupant may not be able to instantly operate the steering device 1C in the intended direction by the intended amount. For this reason, when the uppermost part 21a of the core metal part 21 is gripped, there is a low demand for detecting that the steering device 1C is being gripped.

[0049] D. Other embodiments: D1. Alternative embodiment 1: (1) In the above embodiment, the steering device 1 is mounted on a vehicle VW. Note that the steering device may be provided on a moving body other than a vehicle, such as a ship or an airplane.

[0050] (2) In the above embodiment, the core metal portion 21 is configured symmetrically with respect to the second symmetry plane PS2, which is a plane including the X-axis and the Z-axis, when the rotating unit 10 is in a reference angular position. Note that the core metal portion does not have to be configured symmetrically with respect to the plane including the X-axis and the Z-axis.

[0051] (3) In the above embodiment, the grip portion 20 has a substantially annular shape. For example, the grip portion may have a rectangular or trapezoidal shape when viewed in the Y-axis direction. For example, the grip portion may have a substantially rectangular shape surrounding the periphery of the rotating portion. Also, the grip portion may have a shape that connects to the left and right sides and the lower side in the vertical direction of the rotating portion when the rotating portion is in a reference angular position. Also, the grip portion may be two rod-shaped members that are arranged on both the left and right sides of the rotating portion when the rotating portion is in a reference angular position. For example, in an embodiment in which the grip portion does not have a substantially annular shape, when the rotating portion is in a reference angular position, the uppermost part of the core metal part does not have to be located on the upper side in the vertical direction with respect to the rotating portion, and the lowermost part of the core metal part does not have to be located on the lower side in the vertical direction with respect to the rotating portion.

[0052] (4) In the above embodiment, the core 210 is made of an alloy such as iron, aluminum, magnesium, etc. For example, the core may be made of only iron, only aluminum, or only magnesium.

[0053] (5) In the above embodiment, the soft covering portion 211 is made of polyurethane foam. However, the soft covering portion may be made of a soft material other than polyurethane foam.

[0054] (6) In the first embodiment, the first covering portion 22 is disposed from the top 21a to the bottom 21b of the core metal portion 21. In other words, the first covering portion 22 covers the entire core metal portion 21. The first covering portion may be configured to cover at least a portion of the core metal portion. For example, the first covering portion may be disposed from a portion of the core metal portion that is above the center of rotation of the rotating portion and does not include the top, to a portion of the core metal portion that is below the center of rotation of the rotating portion and does not include the bottom.

[0055] (7) In the above embodiment, first conductive portion 221 and second conductive portion 231 are coatings formed by applying a conductive paint to first insulating portion 223 and second insulating portion 233. Note that, for example, first conductive portion and second conductive portion may be sheet-like members having conductivity.

[0056] (8) In the above embodiment, the first detection unit 220 includes the first shielding unit 222, and the second detection unit 230 includes the second shielding unit 232. The first shielding unit 222 and the second shielding unit 232 are formed by applying paint containing a conductive material to the first insulating unit 223 and the second insulating unit 233. For example, the first detection unit does not need to include the first shielding unit, and the second detection unit does not need to include the second shielding unit. The first shielding unit and the second shielding unit may be, for example, sheet-like members having conductivity.

[0057] (9) For example, the first conductive portion and the second conductive portion may be configured to cover the outer periphery of the metal core portion but not the inner periphery. When an occupant grips the grip portion, it is considered that the occupant often grips a position close to the outer periphery of the metal core portion. Therefore, in an embodiment in which the first conductive portion and the second conductive portion cover the outer periphery of the metal core portion but not the inner periphery, gripping by an occupant can be detected and the area of ​​the first conductive portion and the second conductive portion can be reduced.

[0058] (10) In the above embodiment, the first leading terminal 224a is disposed on the other end 220b side of the first detection unit 220 with respect to one end 220a, and the first trailing terminal 224b is disposed on the other end 220b side of the first detection unit 220 with respect to one end 220a. For example, in a mode in which the detector is disposed between the top of the core metal portion and the rotating portion, the first leading terminal and the first trailing terminal may be disposed on one end side of the first detection unit. Similarly, the second leading terminal and the second trailing terminal may be disposed on one end side of the second detection unit.

[0059] (11) In the first embodiment, the first conductive portion 221 and the second conductive portion 231 are disposed from the periphery of the uppermost portion 21a to the periphery of the lowermost portion 21b of the core metal portion 21. Note that, for example, the first conductive portion and the second conductive portion may be disposed from the uppermost portion to the lowermost portion of the core metal portion so as not to contact each other.

[0060] (12) Fig. 13 is a cross-sectional view of a steering device 1v that is a modified example of the first embodiment. Fig. 13 corresponds to Fig. 8 of the first embodiment. The steering device 1v includes a heater portion 240 between the surface of the core metal portion 21 and the first shield portion 222. Other points of the steering device 1v are the same as those of the steering device 1 of the first embodiment.

[0061] The heater section 240 has a flexible sheet-like configuration with a substantially rectangular outer shape as a main component. The heater section 240 can be formed, for example, by depositing carbon or plating metal on a resin sheet such as PET (Polyethylene terephthalate) or polyamide.

[0062] The heater portion 240 is disposed on the surface of the core portion 21 at a position facing the rotating portion 10, with the two long sides of the rectangle facing each other. The heater portion 240 is connected to a power source. The heater portion 240 generates heat when power is supplied from the power source. As a result, the heat is transmitted to the surface of the first conductive portion 221. Therefore, the occupant can comfortably hold the grip portion 20v of the steering device 1v even in the winter when the temperature is low.

[0063] Since the first shield portion 222 is disposed between the heater portion 240 and the first conductive portion 221, no capacitance is generated between the heater portion 240 and the first conductive portion 221. As a result, detection of the grip of the grip portion 20v using the first conductive portion 221 is stably performed.

[0064] In this modification, the heater section 240 has a sheet-like configuration with a substantially rectangular outer shape and flexibility. However, the heater section 240 can also be configured by applying a conductive paint to the surface of the first shield section 222.

[0065] In the above, the configuration and function of the steering device 1v have been described by taking as an example the side of the steering device 1v where the first detection unit 220 is disposed relative to the first symmetry plane PS1 (see the lower right part of FIG. 3). The steering device 1v has a similar configuration on the side where the second detection unit 230 is disposed relative to the first symmetry plane PS1 (see the lower right part of FIG. 3).

[0066] D2. Alternative embodiment 2: (1) In the above embodiment, the first conductive portion 221 includes the first front conductive portion 221a and the first rear conductive portion 221b, and the second conductive portion 231 includes the second front conductive portion 231a and the second rear conductive portion 231b. For example, the first conductive portion may be one conductive portion extending from the front portion to the rear portion of the surface of the core metal portion, and the second conductive portion may be one conductive portion extending from the front portion to the rear portion of the surface of the core metal portion. Also, for example, the first conductive portion may include the first front conductive portion and the first rear conductive portion, and the second conductive portion may be one conductive portion extending from the front portion to the rear portion of the surface of the core metal portion. For example, the second conductive portion may include the second front conductive portion and the second rear conductive portion, and the first conductive portion may be one conductive portion extending from the front portion to the rear portion of the surface of the core metal portion.

[0067] (2) In the above embodiment, the harness 30 includes a first harness 310 and a second harness 320. For example, in an embodiment in which the first conductive portion includes a first front conductive portion and a first rear conductive portion, and the second conductive portion is a single conductive portion extending from the front portion to the rear portion of the surface of the core metal portion, one harness may electrically connect the first front conductive portion and the second conductive portion. Also, in an embodiment in which the second conductive portion includes a second front conductive portion and a second rear conductive portion, and the first conductive portion is a single conductive portion extending from the front portion to the rear portion of the surface of the core metal portion, one harness may electrically connect the second front conductive portion and the first conductive portion. Also, in an embodiment in which the first conductive portion and the second conductive portion are a single conductive portion extending from the front portion to the rear portion of the surface of the core metal portion, one harness may connect the first conductive portion and the second conductive portion.

[0068] (3) In the above embodiment, the detector 40 includes the first detector 410 and the second detector 420. For example, in an aspect in which the first conductive portion and the second conductive portion are one conductive portion extending from the front portion to the back portion of the surface of the core metal portion, the detector may detect the gripping state of the gripping portion based on a change in electrostatic capacitance occurring in at least one of the first conductive portion and the second conductive portion.

[0069] D3. Alternative embodiment 3: (1) In the above third embodiment, the core metal portion 21 has an annular outer shape, and the third covering portion 22C is disposed from a portion of the core metal portion 21 that is upper with respect to the center of rotation of the rotating portion 10 and does not include the uppermost portion 21a to the periphery of the lowermost portion 21b of the core metal portion 21. For example, in a mode in which the core metal portion has a substantially rectangular shape surrounding the rotating portion, the first conductive portion and the second conductive portion may be disposed from a portion of the core metal portion that is upper with respect to the center of rotation of the rotating portion 10 and does not include the uppermost portion to the periphery of the lowermost portion of the core metal portion.

[0070] (2) In the second and third embodiments described above, when the rotating part 10 is at a reference rotation angle and the steering device 1 is viewed in the +Y direction, the angular range A1 between the first and second detecting parts, centered on the center of the hole 101 formed in the rotating part 10, in a plane including the X-axis and the Z-axis, is configured to be approximately 50°. For example, the angular range between the first and second rear conductive parts may be configured to be 10° or 90°.

[0071] (3) In the above embodiment, the first conductive portion 221 and the second conductive portion 231 have the same length along the outer periphery of the core metal portion 21. The first conductive portion and the second conductive portion may have different lengths along the outer periphery of the core metal portion. For example, the length of the first conductive portion along the outer periphery of the core metal portion may be shorter than the length of the second conductive portion along the outer periphery of the core metal portion.

[0072] D4. Alternative embodiment 4: (1) In the second embodiment, the core metal portion 21 has an annular outer shape, and the grip portion 20 includes two light source bodies that are disposed vertically above the rotating portion 10 and on the surface portion 21A of the core metal portion 21. For example, in an embodiment in which the core metal portion has a substantially rectangular shape surrounding the rotating portion, the grip portion 20 may include two light source bodies that are disposed vertically above the rotating portion and on a portion of the core metal portion that is located on the rear side of the moving body.

[0073] (2) In the second embodiment, the gripping portion 20 includes two light source bodies located vertically above the rotating portion 10. For example, the gripping portion may include one or more light source bodies located other than vertically above the rotating portion. In this embodiment, the covering portion is disposed in a portion of the core metal portion other than where the light source bodies are disposed.

[0074] (3) In the second embodiment described above, the angular range A1 between the first and second detection units, centered on the center of the hole 101 formed in the rotating unit 10, in a plane including the X-axis and the Z-axis, is configured to be approximately 50°. For example, the first detection unit may be disposed around the first light source body and the second detection unit may be disposed around the second light source body so as not to cover the first and second light source bodies shown in FIG.

[0075] (4) In the second embodiment, the grip portion 20 includes two light source bodies, the first light source body 51 and the second light source body 52. ​​The grip portion may include a number of light source bodies other than two, such as one or three. The light source bodies may flash to encourage the occupant to grip the grip portion, or may be lit up when the occupant is not gripping the grip portion.

[0076] The present disclosure is not limited to the above-mentioned embodiment, and can be realized in various configurations without departing from the spirit of the present disclosure.
