Vibration suppression mechanism and terminal support mechanism having vibration suppression mechanism

The present invention relates to a vibration suppression mechanism and a terminal support mechanism having a vibration suppression mechanism.

∙ One end of the control cable may be connected to a vibration source such as a device that generates vibration or a member that propagates vibration. In this case, the control cable transmits the vibration generated by the vibration source, and vibrates to other members such as a guide pipe provided on the other end side of the control cable. As such an event, for example, in the case of a control cable for operating a shift lever connected to a transmission that is a vibration source, a rod member to which the control cable is connected and an inner periphery of a guide pipe that internally supports the rod member. The surface may collide and generate abnormal noise. Regarding the prevention of this abnormal noise, for example, the structure of the terminal device described in Patent Document 1 is known.

<Embodiment 1>
A vibration suppressing mechanism according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the vibration suppression mechanism 1 includes a tubular member 2, a rod member 3 that slides along the inner space 20 of the tubular member 2 along the axial direction, and one end connected to the rod member 3. A cable 4 having the other end connected to the vibration source. The rod member 3 includes a constant diameter portion 31 and a reduced diameter portion 32 adjacent to the constant diameter portion 31, and the reduced diameter portion 32 includes a large diameter portion 32 a having substantially the same diameter as the outer diameter of the constant diameter portion 31. And a small-diameter portion 32 b smaller than the outer diameter of the constant-diameter portion 31. The reduced diameter portion 32 has a large diameter portion 32 a and a small diameter portion 32 b in the circumferential direction of the cylindrical member 2, and the circumscribed circle of the large diameter portion 32 a has the same diameter as the outer diameter of the constant diameter portion 31. The small diameter portion 32 b is concave with respect to the constant diameter portion 31. The cylindrical member 2 has a plurality of elastic members that have a slidable inner diameter between the constant diameter portion 31 and the large diameter portion 32a and each support the rod member 3 from the outer periphery to suppress vibration of the rod member 3. 5, a first elastic member 51 and a second elastic member 52 are provided. In FIG. 1, the rod member 3 is located closest to the vibration source in the sliding range.

The cylindrical member 2 is a holding member that slidably holds the rod member 3 in the axial direction, and here is a guide pipe that guides the sliding of the rod member 3 in the axial direction. The rod member 3 is a member connected to an operation unit that pushes and pulls (push-pull) the end of the cable 4 back and forth along the axial direction of the terminal.

In the vibration suppressing mechanism 1 of the present embodiment, the constant diameter portion 31 is a columnar shape, and the reduced diameter portion 32 is a hexagonal column shape that is a polygonal column shape. The diameter portion 31 is not limited to a cylindrical shape, and may be a column shape having an arbitrary curved surface or a polygonal outer periphery. Further, the reduced diameter portion 32 is not limited to a polygonal columnar shape, and may have an arbitrary large diameter portion 32a and a small diameter portion 32b.

In the vibration suppression mechanism 1 of the present embodiment, the first elastic member 51 is a cap member fitted to the tip of the cylindrical member 2. The second elastic member 52 is an O-ring that is provided on the outer periphery of the cylindrical member 2 and is fitted into a slit 22 having a through hole 23 communicating with the inner space at a part of the groove bottom. It is assumed that a part projects from the inner space 20 into the inner space 20. However, the first elastic member 51 and the second elastic member 52 are not limited to the cap member and the O-ring fitted on the tip of the cylindrical member 2, and slide between the constant diameter portion 31 and the large diameter portion 32a. Any elastic member that has a possible inner diameter and supports the rod member 3 from the outer periphery to suppress vibration of the rod member 3 may be used. That is, the selection of the material of both the

elastic members

51 and 52 and the design of the inner diameter have an inner diameter that allows the constant diameter portion 31 and the large diameter portion 32a to slide, and each supports the rod member 3 from the outer periphery. What is necessary is just to enable it to suppress the vibration of the member 3. FIG.

FIG. 1 is a diagram illustrating an example of a position where the reduced diameter portion 32 coincides with the second elastic member 52 when the rod member 3 moves in the axial direction, and the outer periphery of the constant diameter portion 31 on the operation portion side. Is supported by the first elastic member 51, and the outer periphery of the reduced diameter portion 32 is supported by the second elastic member 52. In this state, as shown in FIGS. 2A and 2B, the first elastic member 51 is in contact with the entire outer periphery of the constant diameter portion 31 of the rod member 3, and the second elastic member 52 is in the rod member 3. The rod member 3 is supported from the outer periphery in contact with a part of the outer periphery of the reduced diameter portion 32. Based on the elastic force, the first elastic member 51 and the second elastic member 52 regulate the radial movement so that the rod member 3 does not vibrate in the direction orthogonal to the axis, and slide in the axial direction. The rod member 3 is supported so as to be movable.

In other words, the large diameter portion 32 a is supported by the second elastic member 52, in other words, the portion of the second elastic member 52 that protrudes into the inner space 20 of the tubular member 2 is the second elastic member 52. It is preferable to set the positional relationship between the large diameter portion 32 a and the second elastic member 52 so that the rod member 3 is supported by the second elastic member 52. Depending on the usage and configuration of the vibration suppression mechanism 1, for example, how it is attached to the operation portion, etc., the position where the second elastic member 52 supports the reduced diameter portion 32 a of the rod member 3. This is because, in such a case, the rod member 3 is supported by the second elastic member 52 because the contact portion of the member with the second elastic member may change.

Next, details of the cylindrical member 2 will be described. As shown in FIGS. 3A to 3C, the cylindrical member 2 has a ring-shaped groove 21 for fitting and fixing the first elastic member 51 to the tip of the cylindrical member 2 on the outer peripheral surface. Have. Further, the cylindrical member 2 has two slits 22 that are opposed to each other for fitting the second elastic member 52 on the outer periphery of the cylindrical member 2. The slit 22 has a through hole 23 communicating with the inner space 20 at a part of the groove bottom. When the second elastic member 52 is fitted and attached to the two slits 22 from the outer peripheral surface side of the cylindrical member 2, a part of the second elastic member 52 extends from the through hole 23 of the slit 22 to the inner space 20. It is formed so that it may protrude. The shape, arrangement, number, combination, and the like of the slits 22 are not limited to those shown in this embodiment. For example, three or more slits 22 may be arranged in a triangular shape, three through holes 23 may be provided, and the rod member 3 may be supported from three sides by an O-ring-shaped first elastic member 52. As long as the second elastic member protruding from the through hole 23 is provided so as to support the rod member 31 so as to be slidable, the arrangement, the number, and the like of the through hole 23 are not limited. .

Next, details of the rod member 3 will be described. As shown in FIGS. 2B and 4A to 4D, the rod member 3 has a constant diameter portion 31a, a reduced diameter portion 32, and other constant diameters along the axial direction thereof. The part 31b is provided adjacent to each other. In the reduced diameter portion 32, large diameter portions 32a having substantially the same diameter as the outer diameters of the

constant diameter portions

31a and 31b and small diameter portions 32b smaller than the outer diameter of the

constant diameter portions

31a and 31b are alternately arranged in the circumferential direction. Each small diameter portion 23b extends in the axial direction. Here, each of the

constant diameter portions

31a and 31b, the reduced diameter portion 32, the large diameter portion 32a, and the small diameter portion 32b represents, for example, the shape of the outer shape based on the central axis of the rod member 3 (particularly, FIG. 2 (b)). When attention is paid to the cross section orthogonal to the axial direction, the reduced diameter portion 32 is a portion having a smaller cross sectional area than the cross sectional area of the constant diameter portion 31. Here, the outer diameters of the constant-

diameter portions

31a and 31b are the diameters of the envelope circles of the constant-

diameter portions

31a and 31b in the axial section, and here the constant-

diameter portions

31a and 31b are cylindrical. These are the diameters (here, the

constant diameter portions

31a and 31b have the same outer diameter). The outer diameter of the large diameter portion 32a is a diameter of a circle passing through each large diameter portion 32a, and the outer diameter of the small diameter portion 32b is a diameter of an inscribed circle inscribed in each small diameter portion 32b.

The rod member 3 has a hole for inserting one end of the cable 4 in the axial direction, and is crimped from the outer surface of the rod member 3 with one end of the cable 4 being inserted into the hole. By this caulking process, the rod member 3 and the cable 4 are firmly connected. The

constant diameter portions

31a and 31b are unprocessed portions that have not been crimped, and the reduced diameter portion 32 is a portion whose cross-sectional area has been reduced by the crimping process. The rod member 3 of the present example is a polygonal columnar shape whose outer shape is substantially hexagonal as a result of caulking that presses a cylindrical member from the outer six directions toward the center of the cross section. The reduced diameter portion 32 is formed. The number of pressing directions is not limited, and may be four directions, for example. In this case, the processed portion, that is, the reduced diameter portion 32 has a substantially quadrangular columnar shape.

FIG. 5 shows a state in which the rod member 3 in FIG. 1 has moved along the axial direction and its position has changed. Note that the rod member 3 is located closest to the operating portion in the sliding range. In this state, as shown in FIGS. 6A and 6B, the first elastic member 51 is in contact with a part of the outer peripheral surface (large diameter portion 32a) of the reduced diameter portion 32 of the rod member 3, and the second elastic member 51 The elastic member 52 is in contact with the entire outer periphery of the constant diameter portion 31 of the rod member 3 and supports the rod member 3 from the outer periphery. Even in this state, the first elastic member 51 and the second elastic member 52 restrict the radial movement so that the rod member 3 does not vibrate in the direction perpendicular to the axis based on the elastic force, and The rod member 3 is supported so as to be slidable in the axial direction. That is, since the rod member 3 such as the reduced diameter portion 32 can be supported by both the

elastic members

51 and 52 regardless of the position within the sliding range in the cylindrical member 2, the vibration suppressing effect is achieved. Is expensive.

The elastic member 5 (the first elastic member 51 and the second elastic member 52) has an inner diameter that can slide between the constant diameter portion 31 and the large diameter portion 32a. That is, the constant diameter portion 31 can slide under the elastic force of the elastic member 5. Further, since the large diameter portion 32a is substantially the same diameter as the constant diameter portion 31 and the large diameter portion 32a is adjacent to the small diameter portion 32b, the elastic force of the first elastic member 51 and the second elastic member 52 is reduced. Originally, the large diameter part 32a is slidable.

Hereinafter, the support of the rod member 3 by the both

elastic members

51 and 52 will be described in detail, and the inner diameters of the both

elastic members

51 and 52 slidable with respect to the rod member 3 will be described. The first elastic member 51 supports the rod member 3 by biasing from the outer periphery of the rod member 3 toward the central axis of the rod member 3. Specifically, the inner diameter of the first elastic member 51 is designed to be slightly smaller than the outer diameter of the rod member 3 (the outer diameters of the

constant diameter portions

31a and 31b and the outer diameter of the large diameter portion 32b). Has been. The first elastic member 51 is expanded by being inserted through the rod member 3, is in close contact with the rod member 3, and supports the rod member 3 (see FIGS. 2A and 5A). On the other hand, when the second elastic member 52 is attached to the cylindrical member 2, a part of the second elastic member 52 projects into the inner space from the through hole 23 and the other part is supported by the groove bottom of the slit 22. The diameter of a circle inscribed in the portion protruding from the through hole 23 of the second elastic member 52 into the inner space is the inner diameter. Specifically, an O-ring can be used for the second elastic member 52, and the inner diameter of the O-ring may be designed to be smaller than the outer diameter of the rod member 3. Then, when the rod member 3 is inserted into the second elastic member 52, the O-ring is pushed and spread by the rod member 3 to be in close contact with the rod member 3, thereby supporting the rod member 3 (FIG. 2B). FIG. 5B). Here, the through-hole 23 is provided in the circumferential direction of the tubular member 2 so that the large-diameter portion 32a and the second elastic member 52 come into contact with each other even when the rod member 3 rotates in the direction around the axis. It is also possible to make the interval to be different from the interval at which the large diameter portion 32b in the circumferential direction of the rod member 3 is provided. On the other hand, the elasticity of both

elastic members

51 and 52 and the inner diameter before supporting the rod member 3 are set to such an extent that the rod member 3 can be supported and sliding of the rod member 3 is not hindered by its restoring force. Thus, it can be said that both the

elastic members

51 and 52 have inner diameters that can slide into the

constant diameter portions

31a and 31b and the large diameter portion 32a, and each has an inner diameter that supports the rod member 3 from the outer periphery. The elastic member 5 may be configured to be able to maintain a shape so as to be separated from the small diameter portion 32b and to be in contact with the large diameter portion 32a when contacting the reduced diameter portion 23.

When the rod member 3 slides with respect to the cylindrical member 2, the boundary portion between the constant diameter portion 31 and the reduced diameter portion 32 slides on the first elastic member 51 or the second elastic member 52. Will pass through. At the boundary portion, there is a step formed by crimping due to the constant diameter portion 31 and the small diameter portion 32b, but the reduced diameter portion 32 has an outer diameter substantially the same as the outer diameter of the

constant diameter portions

31a and 31b. Since it has the large diameter part 32a, both elastic members are hard to get caught in a level | step difference. Therefore, when the boundary portion passes through the position of the second elastic member 52, the slidability of the rod member 3 is not easily inhibited. The case where the second elastic member 52 shown in FIG. 2B is an O-ring will be described as an example. The outer diameter of the rod member 3 is smaller than the outer diameter of the rod member 3 on the O-ring and is elastically applied. When a diameter that is larger than the outer diameters of the

constant diameter portions

31a and 31b is used, the O-ring is expanded by the rod 3, so that there is a gap between the small-diameter portion 32b and the O-ring. become. In the process in which the rod member 3 slides toward the operation portion side, the inner surface side of the O-ring is not easily caught by the stepped portion, so that the sliding is hardly hindered.

The arrangement interval in the axial direction of the first elastic member 51 and the second elastic member 52 is not particularly limited as long as the rod member 3 can be supported by both the

elastic members

51 and 52, but in this embodiment, the diameter is reduced in the axial direction. The length of the portion 32 is shorter. In the case of such an arrangement interval, the sliding range of the rod member 3 is in the above-described range. Therefore, the rod member 3 is supported by the

elastic members

51 and 52. (1) The constant diameter portion 31b is supported by the elastic member 51. (2) The constant diameter portion 31a is supported by the elastic member 52 and the large diameter portion 32a of the reduced diameter portion 32 is supported by the elastic member 52. This is performed according to any of the modes in which the portion 32a is supported by the elastic member 51 (the state shown in FIG. 5). Of course, depending on the distance between the

elastic members

51 and 52, the axial length of the reduced diameter portion 32, the sliding range of the rod member 3, etc., not only the above-described aspect but also only the

constant diameter portions

31a and 31b are provided. In some cases, the

elastic members

51 and 52 are supported, or only the large-diameter portion 32 a is supported by both

elastic members

51 and 52. That is, in this case, the arrangement of the first elastic member 51 and the second elastic member 52 in the axial direction is such that when one contacts the reduced diameter portion, the other can contact the constant diameter portion. Yes. Even if the rod member 3 slides and the relative position between the first elastic member 51 and the second elastic member 52 changes, either the first elastic member 51 or the second elastic member 52 has a constant diameter. Even if it is difficult to suppress the vibration by the elastic member that comes in contact with the reduced diameter portion 23 because the other elastic member is in contact with the constant diameter portion 31, the vibration suppression of the rod member 3 is performed. It can be performed. Further, the number of the second elastic members 51 provided at positions other than the tip of the cylindrical member 2 is not limited to one, and a plurality of second elastic members 51 can be provided along the axial direction of the cylindrical member 2. The material of the first elastic member 51 and the second elastic member 52 can be rubber, for example.

According to the vibration suppression mechanism 1 of the present embodiment, the reduced diameter portion 32 of the rod member 3 has the large diameter portion 32a, and the large diameter portion 32a and the constant diameter portion 31 have the same outer diameter. The constant diameter portion 31 and the reduced diameter portion 32 are at least partially smoothly connected to each other, and the first elastic member 51 or the second elastic member 52 slides between the fixed diameter portion 31 and the reduced diameter portion 32. Mobility is not hindered. In addition, since the vibration suppression mechanism 1 includes a plurality of elastic members 5, that is, the first elastic member 51 and the second elastic member 52, these elastic members 5 regardless of the position after the rod member 3 slides. Both can support the constant diameter part 31 and suppress vibration, and can suppress the collision between the rod member 3 and the cylindrical member 2 that generate abnormal noise.

The rod member 3 is not limited to one having a cylindrical outer shape, and may be any member having an outer shape that can slide in the inner space 20 of the cylindrical member 2. Further, the reduced diameter portion 32 of the rod member 3 can be provided at two or more locations along the axial direction of the rod member 3. When the plurality of reduced diameter portions 32 are provided, the arrangement and shape of the reduced diameter portions may be different from each other.

In the case where there are a plurality of reduced diameter portions 32, by appropriately setting the number and the arrangement relationship of the plurality of elastic members 5 according to the moving range of the rod member 3 sliding with respect to the cylindrical member 2 The vibration suppressing effect can be achieved. In addition, the first elastic member is provided at an intermediate position like the second elastic member 52 without using the cap member fitted to the tip as shown in FIG. 1 as the first elastic member. It may be.

The cable 4 is an inner cable and is inserted into the outer casing 40.

The casing cap 6 is a part that fixes the end of the outer casing 40 coaxially and guides the cable 4 inside the outer casing 40 toward the vibration suppression mechanism 1. The casing cap 6 has a flange portion 6a on the outer periphery near the tip, and has an insertion space 6b into which the end of the outer casing 40 can be inserted. Further, on the inner peripheral side of the flange portion 6a, a stopper portion whose inner diameter is narrowed so as to allow the cable 4 to pass therethrough and prevent the end of the outer casing 40 from passing therethrough is provided. The terminal of the outer casing 40 is fixed to the casing cap 6 by being crimped from the outer peripheral surface 6 c side of the casing cap 6 in a state where the end of the outer casing 40 is inserted into the insertion space 6 b up to the stopper portion.

The socket 7 is provided with a groove 7a, which is a fixing means for attaching the terminal support mechanism 10 to the vehicle, on the outer peripheral surface, and includes a space 7b for accommodating the elastic member 8 and a part of the cylindrical member 2 of the vibration suppressing mechanism 1. An accommodating space 7c is provided on the inner peripheral surface. A fixing bracket 9 is fitted into the groove 7a. The space 7c has a tapered shape that extends outward so that the vibration suppressing mechanism 1 can swing in the direction of the arrow R with the enormous portion 2a as a fulcrum. The bracket 9 is provided on an attachment target (for example, a vehicle body) to which the terminal support mechanism 10 is attached. Here, the terminal support mechanism 10 is fixed to the mounting target by inserting the groove 7a into the substantially U-shaped cutout portion of the bracket 9 provided on the mounting target.
