Description

The present invention relates to a steering wheel connection joint component and a steering wheel connection joint.

The genuine (standard specification) steering wheel mounted on the vehicle may be replaced with another non-genuine (non-standard specification) steering wheel as needed, such as the user's preference. For the purpose of facilitating this replacement work, a steering wheel connection joint has been developed that allows the steering wheel to be attached and detached with a simple operation without using a tool. This steering wheel connection joint is composed of various steering wheel connection joint parts, and as the steering wheel connection joint parts, for example, a quick release member and a steering boss are used.

The quick release member is composed of a socket and a plug. For example, the socket is attached to the steering wheel and the plug is attached to the steering boss. This steering boss is attached to the steering shaft. In this state, the socket fixed to the steering wheel is fitted into the plug fixed to the steering boss, and the steering wheel is connected to the steering shaft. At this time, the plug is inserted into the socket and fixed.

On the outer peripheral surface of the socket, a sleeve operated by an operator is provided so as to be slidable to the plug side and the opposite side, and the socket and the plug are formed so as to be removable with one touch by sliding the sleeve. .. As this attachment / detachment mechanism, for example, a plurality of recesses are provided on the outer peripheral surface of the plug, and a plurality of balls are provided in the socket corresponding to the recesses, and each ball is provided according to the movement of the sleeve by the urging force of the coil spring. A part of the ball is pressed into each recess of the plug to fix the socket to the plug, and as the sleeve moves by the operator's force against the urging force of the coil spring, the individual balls from inside each recess of the plug A mechanism is used to retract a part of each and release the socket from being fixed to the plug.

The socket is attached to the steering wheel by a fixing member such as a bolt. Therefore, the socket is formed with a plurality of mounting holes, which are through holes into which the fixing member is inserted. The sleeve forms a storage chamber on the outer circumference of the socket, and a coil spring is provided in this storage chamber. Each of the above-mentioned mounting holes is connected to the storage chamber for accommodating the coil spring.

The volume of the storage chamber changes according to the movement of the sleeve, but increases as the sleeve moves in the urging direction. Since each mounting hole is connected to this storage chamber, air easily flows into the storage chamber through those mounting holes. Therefore, when the sleeve moves in the urging direction, a large amount of air flows into the storage chamber from each mounting hole, so that the moving speed of the sleeve becomes high. As a result, an abnormal operation, for example, a phenomenon in which the ball bites into the sleeve side and the movement of the sleeve is hindered, and a problem may occur in the attachment / detachment of the socket and the plug.

It is a partial cross-sectional view which shows the socket and the plug in the connected state which concerns on one Embodiment.

An embodiment will be described with reference to the drawings.

(Basic configuration)
As shown in FIG. 1, the steering wheel connection joint 10 according to the embodiment includes a socket 11, a plug 12, and a boss 13. The steering wheel connection joint 10 is a connecting member that connects the steering wheel 20 to a steering shaft (not shown). The socket 11, the plug 12, and the boss 13 are all steering wheel connection joint parts.

The socket 11 is attached to the steering wheel 20 by a fixing member (not shown) such as a bolt. The plug 12 is attached to the boss (steering boss) 13 by a fixing member (not shown) such as a bolt. The boss 13 is attached to the steering shaft by a fixing member (not shown) such as a nut. The steering shaft is a rod-shaped shaft (shaft) whose tip is a male screw, and is provided on the steering column so as to be rotatable around the shaft.

The socket 11 and the plug 12 are formed so that the socket 11 and the plug 12 can be attached and detached with one touch. Various mechanisms can be used as this attachment / detachment mechanism, but the user can attach / detach with one touch without using a tool and without removing a fixing member (not shown) such as a bolt. A mechanism that enables it is used (more on this later).

(plug)
Next, the plug 12 will be described.

As shown in FIGS. 2 and 3, the plug 12 includes a plug main body 41 and a terminal portion 42.

The plug body 41 has a convex portion 41a. The convex portion 41a is formed in a cylindrical shape. A plurality of recesses 41a1 are formed on the outer peripheral surface of the convex portion 41a, and these recesses 41a1 are provided at predetermined intervals in the circumferential direction of the outer peripheral surface. Each recess 41a1 is formed in a spherical groove shape.

The terminal portion 42 is formed to be detachably attached to the plug main body 41, and is fixed to the end surface (end surface on the socket 11 side) of the convex portion 41a by a plurality of fixing members such as bolts. The terminal portion 42 has two terminals 42a (see FIG. 1). One end of a wiring (not shown) passing through the inside of the boss 13 and the inside of the plug body 41 is individually connected to these terminals 42a. The other end of this wiring is connected to, for example, a terminal block of a steering column.

The terminal portion 42 is formed of, for example, a material softer than metal (a material having a hardness lower than that of metal) such as resin. The end surface (exposed surface) of the terminal portion 42 on the socket 11 side is formed so that the corners of the edge are rounded (rounded). From these facts, since the socket 11 can be smoothly fitted into the plug 12, the fitting work can be facilitated.

(socket)
Next, the socket 11 will be described.

As shown in FIGS. 2 and 3, the socket 11 includes a socket body 51, a terminal portion 52, a sleeve 53, an urging member 54, a lid member 55, a plurality of balls 56, and a fixing mechanism 57. I have.

The socket body 51 is formed in a tubular shape. Specifically, a socket insertion hole 51a is formed in the first end surface (end surface on the plug 12 side) of the socket body 51, and the socket body 51 has a recess into which the plug 12 is inserted. As the socket insertion hole 51a, various holes such as a hole having a bottom and a through hole can be used.

A plurality of mounting holes 51b are formed on the second end surface of the socket body 51 (the end surface opposite to the plug 12 side) so as to be arranged in an annular shape at predetermined intervals (see FIG. 1). Each mounting hole 51b is a through hole in which a female screw is machined, and a fixing member (not shown) such as a bolt is individually inserted into each mounting hole 51b.

A plurality of through holes 51c are formed on the side wall of the socket around the socket insertion hole 51a of the socket body 51. Each through hole 51c is a through hole (tapered hole) whose hole diameter gradually decreases from the outer peripheral surface to the inner peripheral surface of the socket side wall. Balls 56 are individually movably fitted in these through holes 51c.

The terminal portion 52 is detachably formed in the socket body 51, and is fixed to the side wall of the socket by a plurality of fixing members such as bolts. The terminal portion 52 has two terminals 52a. One end of a wiring (not shown) that is inserted from the side opposite to the plug 12 side and passes through the socket body 51 is individually connected to these terminals 52a. The other end of this wiring is connected to, for example, a horn provided on the steering wheel 20. Each terminal 52a of the socket 11 is connected to the two terminals 42a of the plug 12 in contact with each other in a state where the socket 11 is fitted in the plug 12 (see FIG. 3).

The sleeve 53 is movably provided on the outer peripheral surface of the socket main body 51, and is formed so as to have an annular storage chamber 53a on the outer peripheral surface of the socket main body 51. The storage chamber 53a is composed of an inner surface of the sleeve 53 and an outer surface of the socket body 51 to create a storage space for accommodating the urging member 54, and is connected to each mounting hole 51b. The sleeve 53 can reciprocate at least along the extending direction of the socket insertion hole 51a, and is reciprocated by the urging member 54 in one of the reciprocating movement directions, that is, the first end face side (plug 12 side: right side in FIGS. 2 and 3). ) Is being urged.

The sleeve 53 has a pressing portion 53b and a restraining portion 53c. The pressing portion 53b pushes the ball 56 in the through hole 51c inside the socket body 51 in response to the movement of the sleeve 53 in the urging direction by the urging member 54. The restraining portion 53c abuts on the ball 56 in the through hole 51c and restricts the movement of the sleeve 53 by the urging member 54 in the urging direction (see FIG. 2). At this time, the ball 56 in the through hole 51c is pushed to the outside of the socket body 51 by the fixing mechanism 57 and fixed (details will be described later).

The urging member 54 is provided in the storage chamber 53a around the socket body 51, and urges the sleeve 53 toward the first end face side (plug 12 side) along the extending direction of the socket insertion hole 51a. As the urging member 54, for example, a coil spring (spring) or the like is used. The coil spring is wound around the outer circumference of the socket body 51 and is provided.

The lid member 55 is formed of an annular plate material, is provided in a storage chamber 53a around the socket main body 51, and closes each mounting hole 51b connected to the storage chamber 53a. Since each mounting hole 51b is closed by the lid member 55, the flow of air flowing from each mounting hole 51b into the storage chamber 53a is obstructed by the lid member 55. As a result, it becomes difficult for air to flow into the storage chamber 53a from each mounting hole 51b, and the amount of air flowing in can be reduced. The lid member 55 is called, for example, a spring seat.

Each ball 56 is movably provided in a plurality of through holes 51c formed in the socket side wall described above. Specifically, each ball 56 is fitted into each through hole 51c, and a fixed position (position of the ball 56 shown in FIG. 2) and a connecting position (ball 56 shown in FIG. 3) along the extending direction of the through hole 51c. (Position) and is provided so that it can be moved. The fixed position of the balls 56 is a position where each ball 56 engages with the restraining portion 53c of the sleeve 53, and the connecting position of the balls 56 is a position where each ball 56 is inserted into each recess 41a1 of the plug 12 inserted into the socket 11. The position to engage.

When the sleeve 53 moves in the urging direction (plug 12 side), each of the above-mentioned balls 56 is pushed by the pressing portion 53b of the sleeve 53 and is pushed from the fixed position (the position of the ball 56 shown in FIG. 2) to the connecting position (FIG. 2). It moves to the position of the ball 56 shown in 3) along the extending direction of the through hole 51c. On the other hand, when the sleeve 53 moves in the direction opposite to the urging direction, each ball 56 has a through hole 51c from the connecting position (the position of the ball 56 shown in FIG. 3) to the fixed position (the position of the ball 56 shown in FIG. 2). It moves along the stretching direction and engages with the restraining portion 53c of the sleeve 53 (details will be described later).

The fixing mechanism 57 is provided in the socket insertion hole 51a. The fixing mechanism 57 pushes a part of each of the individual balls 56 in each through hole 51c of the socket body 51 to the outside of the socket body 51, that is, projects the sleeve 53 to the outside of the socket body 51 to fix the sleeve 53 and secure the socket. It is configured to be pushed and moved by the plug 12 inserted into the insertion hole 51a to release the fixing of the sleeve 53.

The fixing mechanism 57 has a pressing member 57a and an urging member 57b. The pressing member 57a is formed in an annular shape, and is provided in the socket insertion hole 51a so as to be movable along the extending direction of the socket insertion hole 51a. The urging member 57b is, for example, a coil spring or the like, and is positioned on the outer periphery of the terminal portion 52 and is provided in the socket insertion hole 51a. The urging member 57b urges the pressing member 57a toward the first end surface side (plug 12 side: right side in FIGS. 2 and 3) along the extending direction of the socket insertion hole 51a.

The above-mentioned pressing member 57a can be moved to a fixed position (position of the pressing member 57a shown in FIG. 2) and a connecting position (position of the pressing member 57a shown in FIG. 3) along the extending direction of the socket insertion hole 51a. ing. The fixed position of the pressing member 57a is a position where each ball 56 pushes each ball 56 so as to engage the restraining portion 53c of the sleeve 53, and the connecting position of the pressing member 57a is a position where each ball 56 is inserted into the socket 11. It is a position retracted from the fixed position so as to engage with each recess 41a1 of the plug 12.

The above-mentioned pressing member 57a is urged in the urging direction (plug 12 side) by the urging member 57b in a state where the plug 12 is not fitted in the socket 11, and is fixed at a fixed position (position of the pressing member 57a shown in FIG. 2). ) Exists. At this fixed position, each ball 56 is pushed to the outside of the socket body 51 by the pressing member 57a, and a part of each of the balls 56 is pushed out of each through hole 51c of the socket body 51. As a result, each ball 56 engages with the restraining portion 53c of the sleeve 53, and the relative movement of the sleeve 53 with respect to the socket body 51 is restricted.

On the other hand, when the socket 11 is fitted into the plug 12, the pressing member 57a is pushed by the plug 12 that moves in the direction opposite to the urging direction of the urging member 57b, and is in a fixed position (position of the pressing member 57a shown in FIG. 2). To the connecting position (the position of the pressing member 57a shown in FIG. 3). At this connection position, each ball 56 is pushed by the pressing portion 53b of the sleeve 53 and engages with each recess 41a1 of the plug 12, limiting the relative movement of the plug 12 with respect to the socket 11.

(Steering wheel attachment / detachment process)
Next, the flow of the above-mentioned attachment / detachment process of the steering wheel 20, that is, the attachment process (attachment process) and the removal process will be described.

In the mounting step, as shown in FIG. 1, the socket 11 is mounted on the steering wheel 20 by a fixing member (not shown) such as a bolt. Further, the boss 13 is attached to the steering shaft by a fixing member such as a nut (not shown), and the plug 12 is attached to the boss 13 in that state by a fixing member such as a bolt. After that, the socket 11 attached to the steering wheel 20 is fitted into the plug 12, the socket 11 is attached to the plug 12 with one touch, and the steering wheel 20 is connected to the steering shaft. As a result, the installation (installation) of the steering wheel 20 is completed.

In this mounting step, as shown in FIG. 2, the pressing member 57a in the socket body 51 is in a fixed position (the position of the pressing member 57a shown in FIG. 2) before the socket 11 is fitted into the plug 12. At this time, the individual balls 56 in each through hole 51c are pushed to the outside of the socket body 51 by the pressing member 57a, and a part of each of the balls 56 is pushed out of the through hole 51c. As a result, each ball 56 engages with the restraining portion 53c of the sleeve 53, and the relative movement of the sleeve 53 with respect to the socket body 51 is restricted (that is, the sleeve 53 is fixed).

Next, when the socket 11 is fitted into the plug 12, the plug 12 is inserted into the socket insertion hole 51a of the socket body 51. At this time, the pressing member 57a is pushed by the plug 12 against the urging force of the urging member 57b, and from the fixed position (the position of the pressing member 57a shown in FIG. 2) to the connecting position (the position of the pressing member 57a shown in FIG. 3). ). During this process, when the individual balls 56 in each through hole 51c face each recess 41a1 of the plug 12, the engagement between each ball 56 and the restraining portion 53c of the sleeve 53 is disengaged, and the sleeve 53 is attached by the urging member 54. It moves in the urging direction (plug 12 side) depending on the force. In response to the movement of the sleeve 53, as shown in FIG. 3, each ball 56 is pushed inside the socket body 51 by the pressing portion 53b of the sleeve 53 and engages with each recess 41a1 of the plug 12. As a result, the steering wheel 20 is connected to the steering shaft.

On the other hand, in the removal process, the socket 11 attached to the steering wheel 20 is removed from the plug 12 by the movement of the sleeve 53, the socket 11 is removed from the plug 12 with one touch, and the steering wheel 20 and the steering shaft are connected. It will be released. This completes the removal of the steering wheel 20.

In this removing step, the sleeve 53 is operated by an operator and moves in the direction opposite to the urging direction against the urging force of the urging member 54. During this process, when the individual balls 56 in the through holes 51c face the restraining portion 53c of the sleeve 53, the balls 56 can be separated from the recesses 41a1 of the plug 12. At this time, the pressing member 57a moves in the urging direction by the urging force of the urging member 57b, and pushes the plug 12 in the urging direction. As a result, the plug 12 moves in the urging direction, and each ball 56 is separated from each recess 41a1 of the plug 12 and pushed to the outside of the socket body 51 by the outer peripheral surface of the plug 12, and is engaged with the restraining portion 53c of the sleeve 53. It fits.

Next, when the pressing member 57a reaches the fixed position (the position of the pressing member 57a shown in FIG. 2), the individual balls 56 in each through hole 51c are replaced with the outer peripheral surface of the plug 12 by the pressing member 57a to form the socket body 51. Pushed outward, each ball 56 engages the restraint 53c of the sleeve 53. As a result, the relative movement of the sleeve 53 with respect to the socket body 51 is restricted, the plug 12 can be removed from the socket 11, and the connection between the steering wheel 20 and the steering shaft is released.

Here, as shown in FIG. 2, the volume of the storage chamber 53a differs depending on whether the socket 11 and the plug 12 are in the unconnected state and the socket 11 and the plug 12 are in the connected state as shown in FIG. Is different, and the volume of the storage chamber 53a changes according to the movement of the sleeve 53 (the volume of FIG. 3 is larger than that of FIG. 2). Since each mounting hole 51b is connected to the storage chamber 53a, air easily flows into the storage chamber 53a from the mounting holes 51b. Therefore, when the lid member 55 is not present, the only thing that hinders the movement of the sleeve 53 pushed by the urging member 54 is the surface friction, so that the moving speed of the sleeve 53 becomes high.

On the other hand, when the lid member 55 is present, each mounting hole 51b is blocked by the lid member 55, and the air flow is obstructed. As a result, it becomes difficult for air to flow into the storage chamber 53a from those mounting holes 51b, and the amount of air flowing in is reduced, so that the moving speed of the sleeve 53 can be suppressed (attenuation). Therefore, it is possible to prevent an operation abnormality (for example, a phenomenon in which the ball 56 bites into the sleeve 53 side and hinders the movement of the sleeve 53) in the socket 11, which causes a defect in the steering wheel connection joint 10. Occurrence can be suppressed. As a result, for example, it is possible to suppress inquiries and inspection / investigation requests due to initial defects.

Normally, the socket 11 is used in a state of being mounted on the steering wheel 20, but at this time, each mounting hole 51b is in a state of being closed by a fixing member such as a bolt. However, an operator (for example, a user who purchased the product) does not attach the socket 11 to the steering wheel 20 and attaches it to the plug 12 as a single item (in a state where each mounting hole 51b is not blocked by a fixing member). It may be attached and detached. In this case, the storage chamber 53a is in a state where air easily flows in from each mounting hole 51b as described above, but by closing each mounting hole 51b with the lid member 55, the sleeve 53 can be moved as described above. The speed can be suppressed.

Further, even when the socket 11 is attached to the steering wheel 20 and then attached to and detached from the plug 12, each mounting hole 51b is sufficiently closed due to the use of a different type spacer between the steering wheel 20 and the socket 11. It may not be peeled off. In this case as well, the storage chamber 53a is in a state in which air easily flows in from each mounting hole 51b, but by closing each mounting hole 51b with the lid member 55, the moving speed of the sleeve 53 is suppressed as described above. can do.

In order to suppress the inflow of air from each mounting hole 51b, which is a through hole, into the storage chamber 53a, it is possible not to make each mounting hole 51b a through hole, but for example, each mounting hole 51b is "stopped". If the hole (has a bottom) is used, the yield will be lower during thread cutting than the through hole. Further, during the alumite treatment, if there are many "stop screw holes (having a bottom)", liquid dripping such as a dissolution liquid occurs, and the yield is deteriorated. For these reasons, it is desirable to make each mounting hole 51b a through hole.

Further, in order to suppress the moving speed of the sleeve 53, it is possible to weaken the urging force by the urging member 54 such as a coil spring, but the urging force by the urging member 54 maintains the connected state between the socket 11 and the plug 12. Therefore, there is a limit to weakening the force. Therefore, it is difficult to suppress the moving speed of the sleeve 53 by weakening the urging force of the urging member 54.

Further, when the fixing mechanism 57 is not present, the individual balls 56 in each through hole 51c do not engage with the restraining portion 53c of the sleeve 53, and the movement of the sleeve 53 in the urging direction is not restricted. Therefore, the sleeve 53 moves in the urging direction, and each ball 56 is pushed inside the socket body 51 by the pressing portion 53b of the sleeve 53. As a result, a part of each of the balls 56 protrudes into the socket body 51 from each through hole 51c, and the plug 12 cannot be inserted into the socket 11. When performing the attachment / detachment work from this state, the operator operates the sleeve 53, that is, moves the sleeve 53 against the urging force of the urging member 54 to move each ball 56 in each through hole 51c. It is necessary to fit the socket 11 into the plug 12 while maintaining the sleeve position. However, since the connected state of the socket 11 and the plug 12 is maintained by the urging force of the urging member 54, the urging force is strongly set. Therefore, when the attachment / detachment work is performed, the socket 11 and the plug 12 are attached / detached while holding the sleeve position with a strong force that opposes the urging force of the urging member 54. It is difficult.

On the other hand, when the fixing mechanism 57 is present, the individual balls 56 in each through hole 51c are pushed to the outside of the socket body 51 by the fixing mechanism 57 and engage with the restraining portion 53c of the sleeve 53 (see FIG. 2). ). As a result, the movement of the sleeve 53 in the urging direction is restricted, and each part of each ball 56 does not protrude into the socket body 51 from each through hole 51c, and the plug 12 can be inserted into the socket 11. It has become. When the plug 12 is inserted into the socket 11, the sleeve 53 is released from the fixing mechanism 57, the sleeve 53 automatically moves in the urging direction by the urging force of the urging member 54, and the socket 11 and the plug 12 Are concatenated. Therefore, the attachment work (attachment work) of the socket 11 to the plug 12 can be facilitated as compared with the case where the operator fits the socket 11 into the plug 12 while operating the sleeve 53 as described above.

Further, when the socket 11 is removed from the plug 12, each ball 56 in each through hole 51c faces the restraining portion 53c of the sleeve 53 in response to the movement of the sleeve 53 in the direction opposite to the urging direction. The ball 56 is pushed to the outside of the socket body 51 by the fixing mechanism 57 and engages with the restraining portion 53c of the sleeve 53 (see FIG. 2). As a result, the movement of the sleeve 53 in the urging direction is restricted (that is, the sleeve 53 is fixed), and the plug 12 is pushed out by the fixing mechanism 57, which facilitates the work of removing the socket 11 with respect to the plug 12. can do.

As described above, according to the embodiment, the storage chamber 53a is provided with a lid member 55 that closes the plurality of mounting holes 51b connected to the storage chamber 53a. As a result, each mounting hole 51b is blocked by the lid member 55, and the flow of air is obstructed. Therefore, it becomes difficult for air to flow from the mounting holes 51b into the storage chamber 53a, and the amount of air flowing in is reduced. Therefore, the moving speed of the sleeve 53 can be suppressed. Therefore, it is possible to suppress the occurrence of an operation abnormality in the socket 11, and it is possible to suppress the occurrence of a defect in the steering wheel connection joint 10.

Further, the fixing mechanism 57 is provided in the socket 11. As a result, when the plug 12 is inserted into the socket 11, the sleeve 53 is released from the fixing mechanism 57, and the sleeve 53 automatically moves in the urging direction by the urging force of the urging member 54 to move with the socket 11. Since the plug 12 is connected, it is possible to simplify the work of attaching the socket 11 to the plug 12. Further, when the socket 11 is removed from the plug 12, the sleeve 53 is fixed by the fixing mechanism 57, and the plug 12 is pushed out by the fixing mechanism 57, which simplifies the removal work of the socket 11 with respect to the plug 12. It becomes possible. From these things, it is possible to facilitate the attachment / detachment work of the steering wheel connection joint 10.

Further, the fixing mechanism 57 is composed of a pressing member 57a and an urging member 57b. As a result, the fixing mechanism 57 can be realized with a simple configuration.
