Description

The present invention relates to a linked structure.

Conventionally, a connecting structure disclosed in Patent Document 1 has been used to connect a cable operated by an operating portion such as a shift lever to an operated portion such as a transmission. This connecting structure includes an outer member to which a cable operated by the operating portion is connected and an inner member provided in the operated portion.

Japanese Unexamined Patent Publication No. 2020-67169

In the connecting structure of Patent Document 1, a clearance is provided between the peripheral wall of the insertion hole of the outer member and the outer wall of the inner member in order to smoothly perform the relative rotation operation between the outer member and the inner member. However, if this clearance is increased, when the outer member and the inner member rotate relative to each other, their axes are displaced from each other, resulting in rattling. On the other hand, if the clearance is reduced, the rotational resistance of the relative rotation between the outer member and the inner member increases, and the relative rotation operation with respect to each other cannot be smoothly performed.

An object of the present invention is to provide a connected structure in which the occurrence of rattling and the increase in rotational resistance are suppressed.

The connection structure of the present invention includes a terminal member to which a cable is connected and a shaft member rotatably connected to the terminal member about a rotation axis substantially perpendicular to the axial direction of the cable. In the structure, the terminal member has a fitting hole into which the shaft member is rotatably fitted, and the peripheral wall of the fitting hole faces the inside of the fitting hole from the surface of the peripheral wall. A protruding elastic member is provided.

According to the connection structure of the present invention, the occurrence of rattling and the increase in rotational resistance are suppressed.

It is a side view which shows the state after connection of the connection structure of FIG. It is a top view which shows the state after connection of the connection structure of FIG. It is a figure which removed the shaft member and the engaging member from the IV-IV line partial cross-sectional view of the connection structure of FIG. It is a top view which removed the shaft member and the engaging member of the connecting structure of FIG.

Hereinafter, the connection structure of one embodiment of the present invention will be described with reference to the drawings. The embodiments shown below are merely examples, and the connection structure of the present invention is not limited to the following embodiments.

As shown in FIG. 1, the connection structure 1 of the present embodiment includes a terminal member 2 to which the cable C is connected and a shaft member 3 rotatably connected to the terminal member 2. The connection structure 1 is, for example, in an operating force transmission mechanism M including an operation unit P1 such as a shift lever, a cable C operated by the operation unit P1, and an operated unit P2 such as a transmission. It can be provided at a connection point with the portion P2. However, the connecting structure may be applied to applications other than vehicles as long as the terminal member to which the cable is connected and the shaft member are connected to each other so as to be relatively rotatable.

As shown in FIG. 1, the operating force transmission mechanism M including the connecting structure 1 includes an operating unit P1, a cable C connected to the operating unit P1, a terminal member 2 to which the cable C is connected, and a terminal member 2. It has a shaft member 3 rotatably connected to the shaft member 3 and an operated portion P2 connected to the shaft member 3. The operation unit P1 is a portion such as a shift lever that applies an operation force to the cable C. One end side of the cable C is connected to the operation unit P1, and the other end side of the cable C is connected to the terminal member 2. The cable C can be an inner cable of a known control cable. The cable C is routed between the operation unit P1 and the terminal member 2 by a predetermined route. The cable C may be inserted into an outer casing (not shown) in at least a part of the wiring path. The operated portion P2 is a portion operated by the cable C via the terminal member 2 and the shaft member 3, such as a transmission. In the present embodiment, the shaft member 3 is provided on the lever L that is swingably provided on the operated portion P2.

In the operating force transmission mechanism M, the cable C is operated when the operation unit P1 is operated, and the terminal member 2 to which the other end of the cable C is connected is operated by the operation of the cable C. When the terminal member 2 is operated, a force is applied from the terminal member 2 to the shaft member 3 rotatably connected to the terminal member 2. As a result, the lever L connected to the shaft member 3 rotates around the rotation shaft X, and the operating force of the operating portion P1 is transmitted to the operated portion P2 which is a transmission.

As shown in FIGS. 1 and 2, the terminal member 2 is a member to which the cable C is connected and the shaft member 3 is rotatably connected about the rotation shaft X. In the present embodiment, the terminal member 2 is operated by receiving the operating force of the cable C, and transmits the operating force of the cable C to the shaft member 3. However, the terminal member may be configured to be operated by receiving the operating force of the shaft member and transmit the operating force of the shaft member to the cable. As long as the terminal member 2 is connected to the cable C so that the operating force can be transmitted to and from the cable C, the connection method with the cable C is not particularly limited. In the present embodiment, the terminal member 2 is connected to the cable C via a rod R fixed to the end of the cable C.

As shown in FIGS. 1 and 2, the terminal member 2 has a fitting hole 21 into which the shaft member 3 is rotatably fitted. The terminal member 2 is rotatably connected to the shaft member 3 by rotatably fitting the shaft member 3 into the fitting hole 21. The terminal member 2 has a fitting hole 21 in which the shaft member 3 is rotatably fitted around the rotation shaft X so that the shaft member 3 can rotate about the rotation shaft X through the fitting hole 21. The structure of the terminal member 2 is not particularly limited as long as it is connected to. In the present embodiment, the terminal member 2 includes a plate-shaped main body portion 2a and a cylindrical portion 2b protruding from one surface of the main body portion 2a. The fitting hole 21 is provided so as to penetrate both the main body portion 2a and the tubular portion 2b. However, the fitting hole does not have to penetrate both the main body portion 2a and the tubular portion 2b as long as the shaft member 3 can be rotatably fitted. The details of the fitting hole 21 will be described in detail later.

As shown in FIGS. 1 to 3, the terminal member 2 suppresses relative movement with respect to the shaft member 3 in the direction in which the rotation axis X extends (hereinafter, referred to as the rotation axis X direction) via the engagement member 4. It may be connected to the shaft member 3 so as to be. For that purpose, the terminal member 2 includes openings 22a and 22b that communicate the shaft member-side engaging portion 32 of the shaft member 3 and the outside of the terminal member 2, which will be described later. The openings 22a and 22b are provided at two locations of the tubular portion 2b so as to face the rotating shaft X with the rotating shaft X interposed therebetween in a direction substantially perpendicular to the rotating shaft X. The openings 22a and 22b are opened in a size and shape so that the holding portion 41 described later of the engaging member 4 can pass through to engage with the shaft member side engaging portion 32 of the shaft member 3. On both sides of the openings 22a and 22b in the rotation axis X direction, terminal member side engagement portions 23a and 23b that can engage with the engagement member 4 in the rotation axis X direction are provided. In the terminal member 2, the terminal member side engaging portions 23a and 23b engage with the engaging member 4 in the rotation axis X direction, so that the terminal member 2 engages with the engaging member 4 in the rotation axis X direction. Relative movement is suppressed. However, the terminal member may be rotatably connected to the shaft member and may be relatively movable in the rotation axis X direction with respect to the shaft member.

The shaft member 3 is a member rotatably connected to the terminal member 2 about a rotation axis X substantially perpendicular to the axis CX direction (direction in which the axis CX extends) of the cable C. The axis CX direction of the cable C is the axis CX direction of the cable C (direction in which the rod R extends) in the vicinity of the terminal member 2. In the present embodiment, as shown in FIG. 1, the shaft member 3 is rotatably connected to the terminal member 2 and is also connected to a lever L oscillatingly provided on the operated portion P2. The shaft member 3 is operated by transmitting the operating force of the cable C from the terminal member 2, and transmits the operating force transmitted from the terminal member 2 to the operated portion P2. However, the shaft member may be configured to transmit the operating force transmitted to the shaft member to the terminal member.

The shaft member 3 may be configured to rotatably fit into the fitting hole 21 of the terminal member 2, and its structure is not particularly limited. In the present embodiment, as shown in FIGS. 1 to 3, the shaft member 3 includes a fitting portion 31 that rotatably fits with the fitting hole 21 of the terminal member 2. The fitting portion 31 is a shaft-shaped portion to be fitted into the fitting hole 21, and is inserted into the fitting hole 21 to fit into the fitting hole 21. The fitting portion 31 is formed in a substantially columnar shape, and is configured to be rotatable relative to the terminal member 2 around the rotation axis X in a state where the terminal member 2 and the shaft member 3 are connected to each other.

When the shaft member 3 is connected to the terminal member 2 via the engaging member 4 so as to suppress the relative movement with the terminal member 2 in the rotation axis X direction as described above, the engaging member 4 It may be provided with a shaft member side engaging portion 32 (see FIG. 1) capable of engaging with. As shown in FIGS. 1 to 3, the shaft member side engaging portion 32 engages with the holding portion 41 of the engaging member 4 inserted into the openings 22a and 22b of the terminal member 2 (see FIG. 3). .. The shaft member side engaging portion 32 is configured to engage with the engaging member 4 on both sides in the rotation axis X direction. Specifically, the shaft member 3 has a groove 33 extending around the rotation axis X formed on the outer periphery of the fitting portion 31, and the shaft member side engaging portion 32 is in the rotation axis X direction of the groove 33. It is provided on both sides. The shaft member 3 engages with the engaging member 4 on both sides in the rotation axis X direction by engaging the shaft member side engaging portion 32 with the engaging member 4 on both sides in the rotation axis X direction. The relative movement in the rotation axis X direction with respect to the terminal member 2 is suppressed. However, the shaft member may be rotatably connected to the terminal member and may be relatively movable in the rotation axis X direction with respect to the terminal member.

The engaging member 4 is a member that suppresses the relative movement of the terminal member 2 and the shaft member 3 with respect to each other in the rotation axis X direction by engaging with both the terminal member 2 and the shaft member 3. The engaging member 4 is made of a metal wire or the like so as to be elastically deformable when engaged with the terminal member side engaging portions 23a and 23b of the terminal member 2 and the shaft member side engaging portion 32 of the shaft member 3. It is made of a flexible (spring elastic) material. As shown in FIG. 3, the engaging member 4 can be formed by bending one wire rod in a plane perpendicular to the rotation axis X, for example. The engaging member 4 includes a holding portion 41 having a first holding element 41a and a second holding element 41b provided at positions facing the rotation axis X in a direction substantially perpendicular to the rotation axis X. The first sandwiching element 41a and the second sandwiching element 41b are inserted into the openings 22a and 22b on both sides of the terminal member 2, respectively, and sandwich the shaft member 3 in a direction substantially perpendicular to the rotation axis X. It is configured to be engageable with the side engaging portions 23a and 23b and the shaft member side engaging portion 32.

Next, the details of the fitting hole 21 of the terminal member 2 will be described with reference to FIGS. 4 and 5 in addition to FIGS. 1 to 3. In FIGS. 1 to 3, the elastic member 5 shown in FIGS. 4 and 5 is not shown. As shown in FIGS. 1 to 3, the fitting hole 21 is formed in a shape and size so that the fitting portion 31 of the shaft member 3 can be rotatably fitted. As shown in FIGS. 4 and 5, around the rotation axis X of the fitting hole 21, the fitting hole 21 is at least partially surrounded around the rotation axis X to form a circumferential CD around the rotation axis X. A peripheral wall 21a extending along the wall is provided. In the present embodiment, as shown in FIGS. 1 and 2, the fitting hole 21 has a substantially cylindrical shape extending in the rotation axis X direction according to the shape and size of the fitting portion 31 of the shaft member 3. It is formed and sized to have a diameter that is the same as the diameter of the fitting portion 31 or slightly larger than the diameter of the fitting portion 31. Along with this, the peripheral wall 21a is formed so as to extend around the rotation axis X of the fitting hole 21 in the rotation axis X direction. However, the fitting hole 21 is not limited to a substantially cylindrical shape as long as the shaft member 3 can be rotatably fitted, and the fitting hole 21 is not limited to a substantially cylindrical shape, for example, a substantially spherical shape or a substantially elliptical columnar shape. It does not matter if it has the shape of. The peripheral wall 21a is also not particularly limited as long as it is formed so as to extend along the circumferential CD around the rotation axis X, at least partially surrounding the fitting hole 21 around the rotation axis X. It is formed corresponding to the shape of the fitting hole.

As shown in FIGS. 4 and 5, the peripheral wall 21a of the fitting hole 21 is provided with an elastic member 5 protruding from the surface of the peripheral wall 21a toward the inside of the fitting hole 21. Here, the elastic member 5 has at least the fitting hole 21 so that the shaft member 3 smoothly rotates relative to the terminal member 2 or the relative rotation of the shaft member 3 to the terminal member 2 is not hindered. It suffices if it protrudes from the surface of the peripheral wall 21a toward the inside of the fitting hole 21. For that purpose, for example, the elastic member 5 is fitted so that the outer surface of the shaft member 3 (fitting portion 31) fitted in the fitting hole 21 partially contacts the elastic member 5 rather than the entire surface. It may protrude from the surface of the peripheral wall 21a of the joint hole 21 toward the inside of the fitting hole 21.

When the elastic member 5 projects from the surface of the peripheral wall 21a of the fitting hole 21 toward the inside of the fitting hole 21 so that the shaft member 3 connected to the terminal member 2 rotates relative to the terminal member 2. When the shaft member 3 comes into contact with the elastic member 5 protruding from the peripheral wall 21a of the fitting hole 21, the shaft member 3 is suppressed from being displaced, and the rattling of the shaft member 3 is suppressed. Further, when the shaft member 3 comes into contact with the elastic member 5, the elastic member 5 absorbs the impact of the contact, so that the generation of contact noise is also suppressed. Since the elastic member 5 is provided so as to protrude from the surface of the peripheral wall 21a of the fitting hole 21, the surface of the peripheral wall 21a and the outer surface of the shaft member 3 (fitting portion 31) can be provided without providing the elastic member 5. Since the contact area of the shaft member 3 with respect to the peripheral wall 21a can be reduced as compared with the case where the clearance between the shaft members 3 is simply reduced, an increase in the rotational resistance of the shaft member 3 can be suppressed.

The elastic member 5 may project from the peripheral wall 21a of the fitting hole 21 toward the inside of the fitting hole 21, and the position provided in the peripheral wall 21a and the shape of the protruding portion of the elastic member 5 are not particularly limited. In the present embodiment, as shown in FIGS. 4 and 5, the elastic member 5 projects from the surface of a part of the circumferential CD of the peripheral wall 21a toward the inside of the fitting hole 21. That is, the elastic member 5 protrudes from the surface of only a part of the circumferential CD of the peripheral wall 21a, and does not protrude from the surface of the other part of the peripheral CD of the peripheral wall 21a. By projecting the elastic member 5 from a part of the circumferential CD of the peripheral wall 21a in this way, the contact area of the shaft member 3 with the elastic member 5 is increased as compared with the case where the elastic member 5 protrudes from the entire circumferential CD of the peripheral wall 21a. Since it can be made smaller, it is possible to further suppress an increase in the rotational resistance of the shaft member 3. In the present embodiment, as shown in FIG. 5, the elastic member 5 projects from the surface of more than half of the entire circumference of the circumferential CD of the peripheral wall 21a, more specifically, from the surface of about 3/4 of the entire circumference. ing. The length of the circumferential CD of the peripheral wall 21a on which the elastic member 5 protrudes is not particularly limited, but from the viewpoint of reducing the contact area between the shaft member 3 and the elastic member 5, the circumferential CD of the peripheral wall 21a It is preferably about 3/4 or less of the entire circumference, more preferably about 1/2 or less, still more preferably about 1/4 or less.

In the present embodiment, the protruding portion of the elastic member 5 extends from one end 5b of the peripheral wall 21a in the circumferential direction CD to the other end 5c, as shown in FIG. The protruding width W of the elastic member 5 from the peripheral wall 21a is from the maximum protruding portion 5a (the portion having the largest protruding width W in the peripheral direction CD) toward the end portions 5b and 5c along the circumferential direction CD of the peripheral wall 21a. It is getting smaller and smaller. More specifically, the protrusion width W of the elastic member 5 is zero from the maximum protrusion 5a to the end 5b so that the protrusion width W is zero at the ends 5b and 5c separated by a predetermined distance in the circumferential direction CD from the maximum protrusion 5a. It is continuously decreasing toward 5c. The elastic member 5 projects from the surface of the peripheral wall 21a so that the protruding width W of the elastic member 5 gradually decreases toward the ends 5b and 5c along the circumferential direction CD, so that the shaft member 3 becomes the terminal member 2. On the other hand, when the shaft member 3 (fitting portion 31) is relatively rotated, the shaft member 3 (fitting portion 31) is prevented from being caught by the end portions 5b and 5c of the circumferential CD of the elastic member 5, so that the shaft member 3 is relatively rotated with respect to the terminal member 2. Is done smoothly. The protruding width W of the protruding portion of the elastic member 5 can be appropriately set within a range in which the relative rotation of the shaft member 3 with respect to the terminal member 2 is not hindered. For example, the protrusion width W has an outer diameter obtained by subtracting the maximum protrusion width W from the outer diameter of the fitting hole 21 which is substantially the same as the outer diameter of the fitting portion 31 of the shaft member 3, or the fitting portion 31 of the shaft member 3. It can be set to be slightly larger than the outer diameter of.

In the present embodiment, the elastic member 5 projects from the surface of the peripheral wall 21a on the extension line of the cable C in the axis CX direction, as shown in FIGS. 4 and 5. When the push-pull operation load of the cable C is applied to the terminal member 2, the terminal member 2 moves along the axis CX direction of the cable C (the direction in which the push-pull operation load is applied), and the peripheral wall 21a of the terminal member 2 moves. Abuts on the shaft member 3. At that time, since the elastic member 5 is on the extension line in the axis CX direction (direction in which the push-pull operation load is applied) of the cable C, the elastic member 5 comes into contact with the shaft member 3 and the shaft member 3 is displaced. Is suppressed, and the occurrence of rattling of the shaft member 3 is suppressed. Further, at the time of the contact, the elastic member 5 absorbs the impact of the contact, so that the generation of the contact sound is suppressed. In the present embodiment, the elastic member 5 projects from the surface of the peripheral wall 21a so that the maximum protruding portion 5a of the elastic member 5 is located on the extension line in the axis CX direction of the cable C. The above effect can be further enhanced by locating the maximum protruding portion 5a of the elastic member 5 on the extension line of the cable C in the axis CX direction. Further, in the present embodiment, the elastic member 5 is a peripheral wall in a portion of the peripheral wall 21a on the extension line of the cable C in the axis CX direction, which is opposite to the side to which the cable C (rod R) is connected. It protrudes from the surface of 21a. As a result, especially when the pulling operation load of the cable C (the load toward the right side in FIG. 5) is applied to the terminal member 2, the elastic member 5 comes into contact with the shaft member 3, causing the shaft member 3 to rattle. , The contact noise between the terminal member 2 and the shaft member 3 is suppressed. However, the elastic member may protrude from the surface of the peripheral wall 21a on the side to which the cable C is connected among the peripheral wall 21a on the extension line in the axis CX direction of the cable C, or the shaft of the cable C. It may protrude from the surface of the peripheral wall 21a on both sides on the extension line in the CX direction.

In the present embodiment, the elastic member 5 projects from the surface of a part of the peripheral wall 21a in the rotation axis X direction toward the inside of the fitting hole 21, as shown in FIG. That is, the elastic member 5 protrudes from the surface of only a part of the peripheral wall 21a in the rotation axis X direction, and does not protrude from the surface of the other part of the peripheral wall 21a in the rotation axis X direction. In this way, the elastic member 5 protrudes from a part of the peripheral wall 21a in the rotation axis X direction, so that the contact with the elastic member 5 of the shaft member 3 is compared with the case where the elastic member 5 protrudes from the entire peripheral wall 21a in the rotation axis X direction. Since the area can be reduced, an increase in the rotational resistance of the shaft member 3 can be further suppressed.

In the present embodiment, the elastic member 5 is convexly curved and protrudes inward in the radial direction of the peripheral wall 21a, as shown in FIG. When the elastic member 5 is curved and protrudes in a convex shape, the contact of the shaft member 3 with the elastic member 5 becomes closer to point contact (or line contact along the circumferential CD) rather than surface contact, and the contact area becomes smaller. Since it decreases, it is possible to further suppress an increase in the rotational resistance of the shaft member 3. In the present embodiment, the protruding portion of the elastic member 5 is abbreviated in the rotation axis X direction in a cross-sectional view (cross section shown in FIG. 4) when cut along a plane parallel to the rotation axis X direction and the radial direction of the peripheral wall 21a. It has a shape in which the protrusion width W is the largest in the central portion and the protrusion width W becomes smaller as it approaches both ends in the rotation axis X direction. More specifically, the protruding portion of the elastic member 5 has a shape in which a circle (or an ellipse) is partially cut off in a cross-sectional view.

The elastic member 5 may project from the peripheral wall 21a of the fitting hole 21 toward the inside of the fitting hole 21, and the shape and size of the elastic member 5 itself are not particularly limited. In the present embodiment, the elastic member 5 is formed in a ring shape extending along the circumferential direction CD of the peripheral wall 21a, and the central axis 5X of the elastic member 5 is the central axis (rotating axis) of the peripheral wall 21a. It is provided along the circumferential direction CD of the peripheral wall 21a so as to deviate from X). By forming the elastic member 5 in a ring shape, the strength of the elastic member 5 itself can be increased, the installation area with respect to the peripheral wall 21a can be increased, and the elastic member 5 can be more firmly attached to the peripheral wall 21a. Can be done. In the present embodiment, the elastic member 5 has a central axis 5X of the elastic member 5 and a central axis of the peripheral wall 21a so that only a part of the elastic member 5 in the circumferential direction protrudes from a part of the circumferential CD of the peripheral wall 21a. The rotation axis X) is displaced in the direction perpendicular to the rotation axis X (in the illustrated example, in the direction of the axis CX of the cable C, in particular, to the side to which the cable C is connected), and is embedded in the peripheral wall 21a. Has been done.

In the present embodiment, the elastic member 5 is formed in a ring shape having a substantially circular cross section perpendicular to the circumferential direction and extending substantially circularly in the circumferential direction, as shown in FIGS. 4 and 5. However, the cross section of the elastic member may have other shapes such as a substantially elliptical shape and a substantially polygonal shape. Further, the elastic member may be formed in a ring shape having another shape such as a substantially elliptical shape or a substantially polygonal shape. In the present embodiment, the ring-shaped elastic member 5 is formed so that the inner circumference of the elastic member 5 has substantially the same diameter as the peripheral wall 21a. However, the elastic member may be formed so that the inner circumference of the elastic member has a diameter different from that of the peripheral wall. In the present embodiment, the elastic member 5 is embedded in the peripheral wall 21a so that the central axis 5X of the elastic member 5 is substantially parallel to the central axis (rotary axis X) of the peripheral wall 21a. However, the elastic member may be embedded in the peripheral wall so that the central axis of the elastic member intersects the central axis of the peripheral wall.

The elastic member 5 may have elasticity that can absorb an impact when the shaft member 3 comes into contact with the elastic member 5, and the constituent material thereof is not particularly limited. The elastic member 5 is made of a rubber material in this embodiment. As the rubber material, known natural rubber or synthetic rubber can be used, and is not particularly limited, and is not particularly limited, and is EPDM (ethylene propylene diene rubber), NBR (acrylonitrile / butadiene rubber), HNBR (hydrided acrylonitrile / butadiene rubber). ) Etc. are exemplified.
