Description

  The present invention relates to a rotation operation member protruding from the surface of a vehicle instrument panel or the like and a rotation operation device including the rotation operation member, and the instrument panel or the like when the rotation operation member receives a pressing load of a certain level or more. It is related with what can reduce the protrusion amount of the said rotation operation member from the surface of this.

  In a vehicle such as an automobile, generally, a rotary operation member (operation dial) for operating an air conditioner, an audio device, and the like is provided on a panel (for example, an instrument panel) facing the vehicle interior. Most of the rotational operation members are provided so as to protrude from the surface of the panel into the vehicle compartment so that the operation can be received by the passenger.

  It is preferable that the protruding amount of the rotary operation member is designed so as to satisfy both the safety aspect and the operation face. Specifically, in order for the passenger to perform the rotation operation while pinching the rotation operation member, it is desirable to ensure a certain amount of protrusion. On the other hand, assuming that the passenger contacts the protruding portion of the rotation operation member at the time of a vehicle collision or sudden stop, it is desirable that the protrusion amount of the rotation operation member is small from a safety point of view. Some countries regulate the amount of protrusion.

  Therefore, conventionally, as a means for satisfying both safety and operability, when a certain pressing load is applied to the rotating operation member, a part of the rotating operation member is retracted in the pressing direction. Development of devices capable of (that is, the amount of protrusion rapidly decreases) is underway.

  For example, Patent Document 1 discloses a rotary operation device as shown in FIG. This apparatus includes a rotation detection element 110 and a base 120 provided on a circuit board 100, and a holder 140 and an operation knob 150 that constitute a rotation operation member.

  The rotation detection element 110 includes a main body 111 fixed to the circuit board 100 and an operated shaft 112 that protrudes from the main body 111 and is rotatable with respect to the main body 111. A signal corresponding to the rotation of the operated shaft 112 is output. The base 120 is a cylindrical resin part fixed on the circuit board 100 so as to surround the rotation detecting element 110, and supports the holder 140 thereon.

  The holder 140 is connected to the rotation detection element 110 and connects the inner part 141 that contacts the base 20, the outer part 142 provided around the inner part 141, and the inner part 141 and the outer part 142. It consists of a fracture part 143. The breaking portion 143 has a shape that is easily broken when a shear load in a direction parallel to the operated shaft 112 acts between the inner portion 141 and the outer portion 142. The operation knob 150 has a shape that covers the inner portion 141 and the fracture portion 143 of the holder 140 from the outside, and the lower end portion thereof is engaged with the outer portion 142.

  In this rotation operation device, when the operation knob 150 is rotated while being gripped by a finger or the like, the holder 140 and the operated shaft 112 are rotated integrally therewith, and a signal corresponding to the rotation is transmitted from the rotation detection element 110. Is output. On the other hand, when a passenger's human body comes into contact with and presses the operation knob 150 due to a vehicle collision or the like, a pressing force applied from the operation knob 150 to the outer portion 142 of the holder 140 due to the pressing. A shear load due to the load and a support reaction force applied from the base 120 to the holder 140 acts on the fracture portion 143, and the fracture portion 143 breaks when the shear load is a certain level or more. As a result of this breakage, the operation knob 150 settles toward the circuit board 100 as shown in FIG. 11, and the amount of protrusion of the operation knob 150 from the panel (not shown) is rapidly reduced. This sudden decrease in the amount of protrusion significantly reduces the influence of the operation knob 150 on the human body in contact therewith.

JP 2008-79484 A

  In the apparatus, in order to realize the backward movement of the operation knob 150 in an emergency, an increase in the number of parts and a complicated structure are inevitable. Specifically, in addition to the operation knob 150, the holder 140 and the base 120 that supports the holder 140 need to be provided. In addition, the holder 140 has a double structure having an inner portion 141 and an outer portion 142, and a broken portion 143 having a complicated shape must be interposed between the two portions 141 and 142.

  Furthermore, since the breakage portion 143 is broken at a plurality of locations that are greatly separated from the operated shaft 112 in the radial direction and are arranged in the circumferential direction, it is difficult to design for reliably breaking them. Further, even if the operation knob 150 is broken, the possibility that the operation knob 150 moves backward in an inclined posture cannot be denied.

  In view of such circumstances, the present invention has a simple structure and can reliably move backward while maintaining a correct posture when subjected to a pressing force of a certain level or more, and design for that is easy. An object of the present invention is to provide a vehicle rotation operation member and a vehicle rotation operation device including the rotation operation member.

  As means for solving the above-described problems, the present invention provides a panel having a front side facing the vehicle interior, a circuit board held by the panel, and a circuit board provided on the circuit board, from the circuit board to the panel. A rotation operation member for a vehicle provided in a rotation operation device that includes an operation shaft that protrudes toward a front side and is rotatable and includes a rotation detection element that outputs a signal according to the rotation of the operation shaft. And a panel that protrudes from the front side surface of the panel toward the vehicle compartment and is attached to the operated shaft so as to rotate integrally therewith.

  The vehicle rotation operation member has a cylindrical shape surrounding the operated shaft and is fitted to the outside of the operated shaft so as to rotate integrally with the operated shaft, and the inner cylinder portion And an outer portion that is connected to the inner cylinder portion so as to rotate integrally with the inner cylinder portion, protrudes from the front side surface of the panel into the vehicle interior, and receives a rotation operation, and the inner cylinder portion includes the covered portion. And a restricting portion that restricts relative displacement in a direction approaching the circuit board side with respect to the operation shaft and maintains a protruding amount of the outer portion from the panel. The restricting portion is connected to the distal end portion of the inner cylindrical portion, and protrudes radially inward from the inner peripheral surface of the inner cylindrical portion so as to contact the distal end surface of the operated shaft from the distal end side. Including protrusions. The restricting portion further includes the protruding portion separated from the front end surface of the operated shaft when the rotational operation member receives a pressing load of a certain level toward the back side of the panel, and has the same direction as the pressing load. It has a shape that deforms so as to allow relative displacement of the inner cylinder part along the operated shaft in the direction.

  In this vehicle rotation operation member, the inner cylinder portion is fitted to the operated shaft so as to rotate integrally with the operated shaft, and the restricting portion comes into contact with the distal end surface of the operated shaft of the rotation detection element. Thus, the protrusion amount of the rotary operation member from the front side surface of the panel is maintained, so that the outer portion of the rotary operation member can be satisfactorily gripped from the passenger compartment and rotated. In accordance with this rotation operation, the inner cylinder portion and the operated shaft (of the rotation detection element) fitted to the inner cylinder portion rotate together with this, and a signal is output from the rotation detection element correspondingly.

  On the other hand, when a certain pressing load is applied to the rotational operation member from the passenger compartment, the restricting portion is deformed and the inner tube portion is relatively displaced in the same direction as the pressing load. Allow. Due to this relative displacement, the amount of protrusion of the rotary operation member from the front side surface of the panel is rapidly reduced. In addition, since the inner cylinder portion is displaced along the operated shaft while being fitted to the outside of the operated shaft, the rotating operation member is reliably maintained in a correct posture (that is, without being tilted). Can retreat. Further, auxiliary members for realizing the retreat, for example, the base 120 and the holder 140 as shown in FIGS. 10 and 11 are unnecessary, and the outer portion and the inner cylinder held by the rotation operation member itself. With only the combination of the part and the restricting part, it is possible to ensure the amount of protrusion of the outer part from the front surface of the panel at the normal time and to retreat in the emergency (when the pressing load is applied).

  Specifically, as the restricting portion, for example, the protruding portion breaks due to a shearing force caused by a pressing load received by the rotation operation member, or a base end portion and the protruding portion connected to the inner cylinder portion A distal end portion provided, and the distal end portion bends such that the protruding portion retracts from the distal end surface of the operated shaft to the outside in the radial direction when the rotational operation member receives a pressing load of a certain level or more. Those having a deformable shape are preferred.

  Further, the outer portion is further spaced apart from the distal end surface of the operated shaft at a specific distance to the distal end side, and the inner cylinder portion is located with respect to the operated shaft with deformation of the restricting portion. What has an end wall which prevents the relative displacement beyond it by contact | abutting with the front end surface of the said to-be-operated axis | shaft when the relative displacement is carried out by the distance is suitable. This end wall prevents the operated shaft from coming into contact with a human body or the like at the time of the relative displacement, and restricts the amount of the relative displacement to prevent excessive retreat of the rotary operation member.

  The present invention is also a vehicle rotation operation device, a panel having a front side facing the vehicle interior, a circuit board held by the panel, and provided on the circuit board, from the circuit board to the panel. A rotation detecting element that protrudes toward the front side surface and is rotatable and outputs a signal in accordance with the rotation of the operated shaft; a rotation detecting element that protrudes from the front side surface of the panel toward the vehicle compartment side and the There is provided a rotation operation member attached to an operation shaft so as to rotate integrally therewith, and this rotation operation member is the rotation operation member described above.

  In this rotary operation device, at least the tip portion of the operated shaft has a shape in which a part of the cylinder is cut out by a plane, and only the tip of the not-cut column portion of the operated shaft is chamfered. On the other hand, it is preferable that the inner cylinder part has an inner peripheral surface having a shape corresponding to the outer shape of the tip part, and the restriction part is connected to a part of the inner cylinder part corresponding to the plane. is there. These shapes not only reliably prevent relative rotation of the inner cylinder part with respect to the operated shaft, but also the protrusions included in the restricting part are on the flat side, that is, chamfered with respect to the tip surface of the operated shaft. It is possible to abut from the side that is not provided, thereby making it possible to increase the area of the portion where the projection and the tip surface of the operated shaft come into contact.

  Further, in this rotary operation device, the operated shaft is made of a metal material, and at least the inner cylindrical portion and the restricting portion connected to the inner portion of the rotary operation member are formed of a resin material having a lower strength than the metal material. Are preferred. The combination of these materials ensures that the restricting portion of the rotating operation member is deformed (not the operated shaft made of metal material) when the rotating operation member receives a pressing load of a certain level or more.

  As described above, according to the present invention, the rotation operation member itself has a simple structure, and when the rotation operation member receives a large pressing load, the rotation operation member is reliably retracted to the circuit board side in a normal posture. Accordingly, it is possible to achieve both easy operation of the rotary operation member and ensuring safety in the event of a vehicle collision.

It is sectional drawing of the conventional rotational operation apparatus for vehicles. It is sectional drawing which shows the state which the rotation operation member retracted in the rotation operation apparatus for vehicles shown in FIG.

  A first embodiment of the present invention will be described with reference to FIGS.

  1 to 3 show a vehicle rotary operation device according to this embodiment. The apparatus includes a panel 10, a circuit board 20 held by the panel 10, a rotation detecting element 30 mounted on the circuit board 20, a dial ring 40 attached to the panel 10, and the present invention. And an operation dial 50 corresponding to a rotation operation member.

  The panel 10 integrally has an outer wall 12 and a cylindrical portion 14 as shown in FIGS. The outer side wall 12 has a front side surface 15 facing the vehicle interior VR and a back surface 16 on the opposite side, and is arranged in a substantially upright posture. A circular through hole 18 penetrating the outer wall 12 in the thickness direction is provided at a suitable position. The cylindrical portion 14 protrudes rearward from the back surface 16 and has a cylindrical shape surrounding a space communicating with the through hole 18.

  The circuit board 20 has a front side 22 facing the outer wall 12 of the panel 10 and a back side 24 opposite to the front side 22, and the front side 22 is in contact with the rear end surface of the cylindrical portion 14. 10 is held.

  The rotation detection element 30 has an element body 32 and an operated shaft 34. The element body 32 is mounted on the front side surface 22 of the circuit board 20, holds the operated shaft 34 rotatably as will be described later, and outputs a signal corresponding to the rotation of the operated shaft 34 to the circuit board. 20 is output to the circuit formed in 20. The operated shaft 34 is preferably made of a metal material, extends from the element main body 32 toward the outer wall 12 of the panel 10 along the normal direction of the circuit board 20, and is positioned in the through hole 18. The operated shaft 34 has a substantially columnar shape, but at least a tip portion thereof (in this embodiment, most of the portions excluding the base end portion of the operated shaft 34) has a part of the cylinder (upper part in the drawing) being flat. A shape cut out by 35 (a shape having a broad bow-shaped cross section) is formed. Moreover, it has the shape where only the front-end | tip of the cylindrical part which is not notched among the said to-be-operated shafts 34 was chamfered. That is, an inclined surface 36 is formed at the tip portion excluding the flat surface 35 so as to decrease in diameter toward the front.

  The dial ring 40 includes a cylindrical portion 42 that is fitted inside the inner cylindrical portion 14 of the panel 10, and an inner wall portion 44 that is connected to an inner peripheral surface of an intermediate portion in the axial direction of the cylindrical portion 42. The inner wall portion 44 has a donut plate shape that fills a gap between the cylindrical portion 42 and the element body 32, and contributes to an improvement in aesthetics. The dial ring 40 is not essential to the present invention and can be omitted as appropriate.

  The operation dial 50 includes a dial body 60, a dial top 52, and a decorative ring 54, and constitutes a vehicle rotation operation member according to the present invention.

  The dial body 60 includes an inner cylinder portion 62, an outer cylinder portion 64, an inner wall portion 63, and a restriction portion 66, and the entire dial body 60 including these is lower in strength than the operated shaft 34. It is molded integrally with the material. The outer cylinder portion 64 and the inner wall portion 63 together with the dial top 52 and the decoration ring 54 constitute an outer portion according to the present invention.

  The inner cylindrical portion 62 has a cylindrical shape surrounding the operated shaft, more specifically, a cylindrical shape having an arcuate inner peripheral surface corresponding to the outer shape of the main portion of the operated shaft 34. It is fitted outside the main part (part including the tip part). By this fitting, relative rotation of the inner cylinder part 62 with respect to the operated shaft 34 is prevented. Further, in this embodiment, the fitting between the two is set or a not-shown retaining structure is provided so that the operation dial 50 is not pulled out from the operated shaft 34 even if the operation dial 50 is pulled with some force. .

  The outer cylindrical portion 64 has a cylindrical shape surrounding the inner cylindrical portion 62 from the outside (in this embodiment, a cylindrical shape that is slightly reduced in diameter toward the distal end side), and an appropriate portion thereof defines the inner wall portion 63. And connected integrally with the rear end portion of the inner cylinder portion 62 (that is, so as to rotate integrally with the inner cylinder portion 62). The outer cylindrical portion 64 has an outer diameter that is slightly smaller than the inner diameter of the cylindrical portion 42 of the dial ring 40. Most parts of the outer cylinder portion 64 protrude from the front side surface 15 of the panel 10 to the vehicle interior VR side (left side in FIGS. 3 and 4) and are gripped from the outside in order to rotate the operation dial 50.

  The restricting portion 66 is connected to the distal end portion of the inner cylindrical portion 62, and the inner cylindrical portion 62 is relatively displaced in a direction approaching the circuit board 20 side (rightward in the drawing) with respect to the operated shaft 34. By restricting, it has the control part which keeps the protrusion amount of the said outer side part from the said panel. Specifically, the restricting portion 66 protrudes further forward from the tip of the portion (the upper portion in the figure) corresponding to the cut-out plane 35 of the operated portion 34 of the inner cylinder portion 62, and the inner cylinder A restricting claw (projecting portion) 68 projecting inward from the inner surface of the portion 62 is provided. The cross-sectional dimension of the restricting claw 68 is such that the relative displacement occurs when the rear end surface of the restricting claw 68 abuts on the front end surface 38 of the operated shaft 34 in a normal state where no pressing load is applied to the operation dial 50. While restricting (displacement toward the circuit board 20 side), the operation dial 50 is directed from the vehicle compartment VR side to the back side of the panel 10 (from the left side to the right side in FIGS. 3 and 4) above a certain level. When the pressing load is applied, the restriction claw 68 breaks due to the shearing force corresponding to the pressing load, and the inner cylindrical portion 62 is relatively moved along the operated shaft 34 in the same direction as the pressing load. The displacement (the rightward displacement in FIG. 3) is set to be allowed.

  The dial top 52 corresponds to an end wall according to the present invention, and is arranged at a position spaced apart from the distal end surface 38 of the operated shaft 34 by a specific distance Z (FIG. 3). At this position, the outer cylindrical portion 64 is fixed via the decorative ring 54.

  The dial top 52 may be formed integrally with the dial body 60 (omitting the decorative ring 54). That is, the entire rotation operation member according to the present invention may be integrally formed.

  Next, the operation of the vehicle rotation operation device will be described.

  In a normal state immediately after the assembly of the apparatus is completed, the operation dial 50 is positioned at a position where the restricting claw 68 of the restricting portion 66 of the operation dial 50 abuts on the tip surface 38 of the operated shaft 34 as shown in FIGS. The most part of the operation dial 50 projects greatly from the front side surface 15 of the panel 10 toward the vehicle interior VR. Therefore, the operator can rotate the dial main body 60 of the operation dial 50, more specifically, while holding the outer peripheral surface of the outer cylinder portion 64 with a finger or the like. In accordance with this rotation operation, the inner wall portion 63, the inner cylinder portion 62, and the operated shaft 34 into which the inner cylinder portion 62 is fitted rotate integrally with the outer cylinder portion 64, and the rotation of the operated shaft 34 is performed. The element main body 32 of the rotation detecting element 30 outputs a signal corresponding to.

  On the other hand, when the passenger's human body comes into contact with the operation dial 50 due to a vehicle collision or the like and is strongly pressed from the passenger compartment VR side (left side in FIGS. 3 and 4), the inner cylinder A pressing load along the axial direction acts on the portion 62, and this pressing load acts as a shearing load on the restricting claw (projecting portion) 68 of the restricting portion 66 connected to the inner cylinder portion 62.

  When the pressing load (shear load) is a certain level or more, the restriction claw 68 breaks, and this breakage causes the inner cylindrical portion 62 to move toward the circuit board 20 along the axial direction with respect to the operated shaft 34 (see FIG. 3 and the right side in FIG. This relative displacement is allowed up to the position where the front end surface 38 of the operated shaft 34 contacts the back surface of the dial top 52, that is, the position shown in FIG. As a result, the amount of protrusion of the operation dial 50 from the front side surface 15 of the panel 10 is sharply reduced, the influence of the operation dial 50 on the human body is remarkably reduced, and the amount of decrease is the tip of the operated shaft 34. The distance Z (FIGS. 4 and 6) from the surface 38 to the back surface of the dial top 52 is restricted. That is, excessive immersion (retraction) of the operation dial 50 is prevented. Moreover, since the inner cylindrical portion 62 is displaced along the operated shaft 34 while being fitted to the outside of the operated shaft 34, the operation dial 50 is tilted while maintaining the whole in a correct posture (that is, tilting). (Without) can definitely move backwards.

  Further, an auxiliary member for realizing the backward movement, for example, the base 120 and the holder 140 as shown in FIGS. 10 and 11 are unnecessary, and only the structure held by the operation dial 50 itself is used. It is possible to secure the amount of protrusion of the outer portion from the front surface of the panel at the time of retreat and retreat in an emergency (when a pressing load is applied).

  The restricting portion according to the present invention may be any one that can be deformed so as to allow displacement of the rotary operation member in the same direction as the direction of the pressing load due to the load when the excessive pressing load is applied. Is not limited to breakage of the restricting claw 68 as described above. For example, as shown in FIGS. 7 to 9 as the second embodiment, the restriction claw 68 may be deformed instead of being broken.

  The apparatus according to the second embodiment includes the panel 10, the circuit board 20, the rotation detecting element 30, and the operation dial 50 as in the first embodiment, and the configuration of the operation dial 50 is also included in the restricting portion 66. Instead, it is the same except that a restricting portion 66 'is provided. The restricting portion 66 ′ according to the second embodiment has a restricting claw 68 that can abut on the tip surface 38 of the operated shaft 34 like the restricting portion 66, but the restricting portion 66 ′ has an operation dial. When 50 receives a pressing load of a certain level or more, the restricting claw 68 is bent and deformed so as to retract from the distal end surface 38 of the operated shaft 34 to the outside in the radial direction.

  Specifically, the restricting portion 66 ′ has a restricting portion main body 67 having a base end portion connected to the inner cylinder portion 62 and a tip end portion on the opposite side (dial top 52 side). The restricting claw 68 protrudes in the direction. The restricting portion main body 67 has a shape that allows bending displacement in the radial direction of the distal end portion and the restricting claw 68 formed on the distal end portion with the base end portion as a fulcrum, that is, a cantilever shape. The cross-sectional shape of the restricting portion main body 67 is such that when a certain pressing load is applied to the operation dial 50, the restricting claw 68 is detached from the distal end surface of the operated shaft 34 radially outward due to the pressing load. It is set so as to have a bending rigidity that allows the bending displacement until it does. In particular, in this embodiment, a pair of slits 65 opened on the distal end side are formed between the outer side portions of the base end portion of the restricting portion main body 67 and the inner cylinder portion 62, whereby the inner cylinder portion 62 is formed. The required length of the restricting portion main body 67 can be ensured while suppressing the amount of protrusion of the restricting portion 66 '.

  Also in the second embodiment, the control claw 68 comes into contact with the front end surface 38 of the operated shaft 34 from the front end side during normal use, whereby the operation dial 50 toward the circuit board 20 with respect to the operated shaft 34 is obtained. The relative displacement of the operation dial 50 is restricted, and the projection amount of the operation dial 50 from the panel front side surface 15 is ensured. On the other hand, when an excessive pressing load is applied to the operation dial 50, the restricting claw 68 is detached from the distal end surface 38 with the deformation of the restricting portion 66 ', and the inner cylinder is directed in the same direction as the direction of the pressing load. When the relative displacement of the portion 62 with respect to the operated shaft 34 is allowed, the operation dial 50 is retracted toward the circuit board 20 and the amount of protrusion is rapidly reduced.

  In the present invention, the specific cross-sectional shape of the operated shaft 34 and the inner peripheral surface shape of the inner cylinder portion 62 corresponding thereto are not limited to those described above. If these shapes are shapes other than a circle, the relative rotation of the inner cylindrical portion 62 with respect to the operated shaft 34 is restricted, and the rotation of the operation dial 50 is transmitted to the operated shaft 34. However, as in the first and second embodiments, at least the tip portion of the operated shaft 34 has a shape in which a part of a cylinder is notched in the plane 35, and the notched portion of the operated shaft is notched. An inner peripheral surface having a shape in which only the tip of a cylindrical portion that is not cut is chamfered (that is, an inclined surface 36 is provided), and the inner peripheral surface of the inner cylindrical portion 22 corresponds to the outer shape of the tip portion. If the restricting portion 66 (66 ′) is connected to a portion of the inner cylinder portion 62 corresponding to the flat surface 35 (upper portion in the illustrated example), the restricting portion 66 (66 ′) The restricting claw 68, which is a protruding portion included in the operation shaft 34, can abut against the distal end surface 38 of the operated shaft 34 from the side of the flat surface 35, that is, the side that is not chamfered. Without increasing the amount of protrusion And Seitsume 68 and the distal end surface 38 of the operated shaft 34 to be a large area of the portion in contact.

  In the present invention, the specific material of each member is not limited. However, the operated shaft is made of a metal material, and at least the inner cylinder portion of the rotary operation member (the operation dial 50 in each embodiment) and the restriction portion (the dial body 60 in each embodiment) connected thereto. Is formed of a resin material whose strength is lower than that of the metal material, when the rotation operation member receives a pressing load of a certain level or more (not a metal material operated shaft), the restricting portion of the rotation operation member To ensure that it deforms.
