Description

  The present invention relates to an ignition switch device that permits starting of an engine on the condition that an ID code from a transmission means is determined to be a regular one registered in advance.

  In order to prevent theft of vehicles that frequently occur in recent years, the vehicle includes a transmission unit that can transmit a vehicle-specific ID code while being carried by a driver, and a reception unit that can receive the ID code. A so-called smart entry system has been proposed that allows various operations of the vehicle including engine start, provided that the ID code is genuine. For example, in the case of a smart entry system in a motorcycle, when the driver carrying the transmission means (electronic key) approaches the vehicle, the reception means receives the ID code transmitted from the transmission means, and is registered in advance. Whether the engine is present or not is determined, and the engine start operation is enabled only when the engine is genuine.

  However, a motorcycle equipped with the smart entry system as described above conventionally has an operation knob that can be rotated on condition that it has been determined that a legitimate ID code has been received. Thus, an ignition switch device has been proposed in which the engine can be started (see, for example, Patent Document 1). In such an ignition switch device, the rotation operation of the operation knob is restricted until a proper ID code is received, and the operation knob is idled when the forceful rotation operation is attempted in the restricted state. A torque limiter mechanism is provided.

The torque limiter mechanism includes a spring (spring) extending in a radial direction (a direction orthogonal to the rotation direction of the operation knob) with respect to the operation knob, and a click ball that presses the operation knob by the biasing force of the spring. The recess is formed on the operation knob side and accommodates the click ball in a fitted state. When the operation knob is forcibly rotated, the click ball is released from the recess and the operation knob is idle. I was supposed to. This can prevent the engine from being illegally started.
Japanese Patent Laid-Open No. 2005-1112048

  However, in the conventional ignition switch device, since the spring extends in the radial direction with respect to the operation knob, for example, a mechanical key or the like is extended from substantially the center of the operation knob, and the operation knob and the mechanical key are When applied to a detachable one, there is a problem that a relatively small spring must be used, and a sufficient pressing force of the click ball against the recess cannot be obtained.

  In other words, in the case of an operation knob having a mechanical key extended as described above, the mechanical key formation site becomes an obstacle, and it is difficult to provide a spring having a long overall length and a large biasing force. Therefore, the click ball is pressed against the concave portion by a spring having a short urging force, and the operation knob rotates idly even with a relatively small torque. Therefore, even when an attempt is made to rotate the operation knob when a proper ID code is received, there is a possibility that the operation knob may accidentally rotate idle.

  The present invention has been made in view of such circumstances, and avoids accidental rotation of the operation knob when the operation knob is rotated when a proper ID code is received. It is an object of the present invention to provide an ignition switch device capable of achieving the above.

The invention according to claim 1 is a transmission means that can be carried by the driver and can transmit a vehicle-specific ID code, a reception means that can receive an ID code transmitted from the transmission means, and a reception means that receives the ID code. Determining means for determining whether or not the registered ID code is a regular one registered in advance, an operation knob that can be operated by the driver, and a rotating operation of the operating knob. The rotor that is allowed to start the engine and the rotation of the rotor are restricted, and the rotation of the rotor is performed on condition that the ID code received by the receiving unit is determined to be valid by the determining unit. A regulating means for releasing the regulation of movement, and when the turning of the rotor is regulated by the regulating means and the operating knob is rotated with an operating force of a predetermined torque or more, the operating knob is On the rotor In the ignition switch device provided with the idling means for rotating relatively and idling, the operation knob has a knob part formed in a convex shape on the upper part and the knob part separately from the knob part. And a transmission unit that can be rotated together with the knob to transmit the rotation to the rotor, and the idler means is formed in the transmission unit and extends in the rotation axis direction of the operation knob. A spring, a pressing means that presses the knob with the urging force of the spring, and a recess that is formed in the knob and accommodates the pressing means in a fitted state ; and a recess in the knob The bulging part which bulged from the edge in the said transmission part side was formed in the substantially annular shape, It is characterized by the above-mentioned.

According to a second aspect of the invention, in the ignition switch device according to claim 1 Symbol mounting, the pressing means and recess, characterized in that formed pair to each of the knob portion and a radial direction of the transfer portion collinear And

According to a third aspect of the present invention, in the ignition switch device according to the first or second aspect , the rotor includes a key cylinder having a plurality of tumblers through which a normal mechanical key can be inserted, and the transmission portion. Is characterized in that the mechanical key is integrally formed.

A fourth aspect of the present invention is the ignition switch device according to any one of the first to third aspects, wherein the surface of the rotor faces the transmission portion and the surface of the transmission portion faces the rotor. Are characterized in that fitting shapes that can be fitted to each other are formed.

According to a fifth aspect of the present invention, in the ignition switch device according to any one of the first to fourth aspects of the present invention, the tension switch is interposed between the knob and the transmission unit, and is applied to the transmission unit. It has the O-ring which can assemble | attach a knob part, having it.

  According to the first aspect of the present invention, since the spring constituting the idling means extends in the direction of the rotation axis of the operation knob, a long spring can be used, and the biasing force applied to the pressing means can be reduced. It can be set larger. Therefore, when the operation knob is rotated when a regular ID code is received, it is possible to avoid the operation knob from being accidentally idle.

Further , since the bulging portion bulging from the edge of the concave portion of the knob portion toward the transmitting portion is formed in a substantially annular shape, the concave portion is formed deeply by the bulging dimension of the bulging portion, and the regulating means In the axial direction of the ignition switch device, when the operation knob is forcibly turned in a state where the rotation of the rotor is restricted, the torque when the pressing means is disengaged from the concave portion and the idling is set large is set. It is possible to suppress an increase in the size of the. Therefore, when the operation knob is turned when the regular ID code is received, it is possible to more reliably avoid the operation knob from being accidentally idle.

According to the invention of claim 2 , since the pressing means and the recess are formed in a pair on the same straight line in the radial direction of the knob and the transmission part, the rotation of the rotor is restricted by the restricting means. When the operating knob is forcibly rotated at a predetermined torque or more, the pressing means that has been disengaged from one of the recesses is fitted into the other recess by further rotating the knob by 180 °. Will be.

  Therefore, even after the operation knob is forcibly rotated at a predetermined torque or more in a state where the rotation of the rotor is restricted by the restricting means, the idle knob portion is in a stable position every 180 ° (the pressing means is recessed). Therefore, the convex direction formed on the upper part of the knob can always be kept the same, and the operability of the operation knob can be maintained.

According to the invention of claim 3 , the rotor is composed of a key cylinder having a plurality of tumblers and capable of inserting a regular mechanical key, and the mechanical key is integrally formed in the transmission portion. Therefore, the mechanical key can be operated even when the ID code cannot be transmitted from the transmitting means due to a battery exhaustion or the like.

According to the invention of claim 5 , since the O-ring that is interposed between the knob and the transmission part and can assemble the knob while having a pressing force with respect to the transmission part is provided. In this case, it is possible to suppress the occurrence of play between the knob portion and the transmission portion.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The ignition switch device according to the present embodiment is for controlling engine start and stop in a two-wheeled vehicle. As shown in FIGS. 1 and 2, an ignition switch body 1 including a cylinder body and an upper portion thereof are formed. The external appearance is mainly composed of the operation knob 2. Of these, the operation knob 2 is rotatable between an on position where the engine E can be started, an off position where the engine E is stopped, and a steering lock position where the handlebar is locked.

  Further, as shown in FIG. 10, the ignition switch device according to the present embodiment includes a transmission unit 14 that can be carried by the driver and can transmit a vehicle-specific ID code, and a transmission unit 15 that is disposed on the vehicle side. Receiving means 15 capable of receiving the ID code from the receiver, and determining means 16 for determining whether or not the ID code received by the receiving means 15 is a registered regular one.

  The transmission means 14 can always transmit an ID code by radio waves or the like. When a driver carrying the transmission means 14 approaches the vehicle and performs a predetermined authentication operation, the reception means 15 including a vehicle-side antenna or the like. Is configured to receive the ID code. The determination unit 16 compares the ID code registered in advance with the ID code received by the reception unit 15 and determines that a regular ID code has been received if they match.

  In addition, as shown in FIG. 2, the operation knob 2 has a mechanical key K formed integrally therewith, and a key that has a plurality of tumblers in the ignition switch body 1 and allows the regular mechanical key K to be inserted therethrough. A cylinder 4 (rotor) is provided. When the mechanical key K is not inserted, the key cylinder 4 protrudes outwardly to restrict the rotation, and when the mechanical key K is inserted, the tumbler is drawn into the interior, and the key cylinder 4 is engaged with the outside. The match is solved and the rotation is enabled.

  An operating element 5 that can be rotated together with the key cylinder 4 is disposed below the key cylinder 4, and an extended portion 5 a extending from the operating element 5 is projected to be illustrated. A lock bar R that can be engaged with a rotation shaft of the handle bar that is not locked to lock the handle bar is connected to a movable member 9 that constitutes the ignition switch 7. For example, when the operation knob 2 is turned from the off position to the steering lock position, the lock bar R is in a protruding state to lock the handle bar, and when the operation knob 2 is turned from the off position to the on position, the operation is movable. As the member 9 rotates, the movable contact 9a operates to come into contact with and away from a fixed contact (not shown) on the substrate 8.

  As shown in FIG. 10, the ignition switch 7 is electrically connected to an engine E (specifically, an ECU that controls the engine E), and a predetermined circuit is formed by the ignition switch 7. The engine E is allowed to start. When the start button (not shown) separately provided is pressed in a state where the start of the engine E is permitted, the engine E is started. That is, if the normal mechanical key K is inserted into the key cylinder 4 and the operation knob 2 is turned, the key cylinder 4 is turned along with the turning operation, and the start of the engine of the motorcycle can be permitted. It is like that.

  On the other hand, in the ignition switch body 1, the key cylinder 4 is restricted from rotating, and the key cylinder 4 is provided on the condition that the ID code received by the receiving unit 15 is determined by the determining unit 16 to be genuine. A restricting means 6 for releasing the restriction of the rotation is provided. More specifically, the restricting means 6 is electrically connected to the determining means 16, and the position between the position where the tip 6 bb is engaged with the notch 5 b formed in the operating element 5 and the position where the disengaged is disengaged. And a solenoid 6a having a plunger 6aa connected to the base end 6ba of the arm 6b.

  If the determination means 16 determines that the ID code received by the receiving means 15 is authentic, the solenoid 6a is energized, and the energization attracts the plunger 6aa downward. Move. As a result, the base end 6ba of the arm 6b is also pushed downward, the arm 6b swings about the axis L, and the tip 6bb is separated from the notch 5b, so that the actuator 5 and the key cylinder 4 are unlocked. Is done. In this state, if the operation knob 2 is turned to the ON position, the key cylinder 4 is turned and the start of the engine E is permitted.

  The notch 5b formed in the actuator 5 is formed at a position corresponding to the ON position and the steering lock position of the key cylinder 4, and when the tip 6bb of the arm 6b is latched, the ON position or the steering lock The key cylinder 4 in the position can be locked by restricting the rotation. However, when the key cylinder 4 is in the on position and the steering lock position, the movement of the tumbler is restricted, so that the mechanical key K is not extracted from the key cylinder 4.

  Here, as shown in FIG. 3, the operation knob 2 in the present embodiment has a knob portion 2a having an upper portion formed in a convex shape 2aa, and the knob portion 2a are separated from the knob portion 2a. It has a transmission part 2b that can be rotated to transmit its rotation to a key cylinder 4 as a rotor via a mechanical key K, and an idler means 3 comprising a spring 10, a ball 11 as a pressing means, and a recess 12. Yes.

  The knob portion 2a is formed so that the convex portion 2aa at the upper part thereof extends in a substantially straight line so that the driver can easily pick it, and the transmission portion 2b is accommodated therein. That is, a spring pin P extending inward is formed in the knob portion 2a, and the tip of the spring pin P is inserted into an annular groove 2ba formed in substantially the entire side surface of the transmission portion 2b to prevent the spring pin P from coming off. By doing so, both members are integrated. The mechanical key K is integrated with the transmission portion 2b by insert molding, and the mechanical key K is extended from the lower surface of the transmission portion 2b.

  Each of the springs 10 is formed in the transmission portion 2b and extends in the direction of the rotation axis of the operation knob 2 (the vertical direction in FIG. 3). Each ball 11 presses the knob portion 2a (the bottom surface of the recess 12 formed in the knob portion 2a) by the urging force of the spring 10. That is, as shown in FIG. 4, the spring 10 and the ball 11 are formed in a pair on the same straight line in the radial direction of the transmission portion 2b, and the ball 11 is pulled by the urging force of the spring 10 on the back surface of the knob portion 2a. It is pressed by the recess 12 formed on the side.

  As shown in FIG. 5, the recesses 12 are formed at positions corresponding to the balls 11 in the knob 2a, and are formed in a pair on the same straight line in the radial direction of the knob 2a. However, when the transmission portion 2b is assembled in the knob portion 2a, the ball 11 biased by the spring 10 is accommodated in a fitted state. As a result, when the turning operation on the operation knob 2 is performed in a state where the restriction by the restriction means 6 is released, the transmission portion 2b is also turned together with the knob portion 2a, and the key cylinder 4 is turned via the mechanical key K. Configured to get.

  Further, when the rotation of the key cylinder 4 is restricted by the restricting means 6 and the operation knob 2 is forcibly turned by an operation force equal to or greater than a predetermined torque, the ball 11 is fitted into the recess 12. It is configured so that it is disengaged and idles. That is, when the knob portion 2a is forcibly rotated with an operation force equal to or greater than a predetermined torque, the ball 11 rides on the recess 12 and the fitting force of the ball 11 to the recess 12 is released as shown in FIG. The part 2a rotates relatively with respect to the transmission part 2b and idles.

  Accordingly, when the rotation of the key cylinder 4 is restricted by the restriction means 6 and an attempt is made to forcibly rotate with an operation force of a predetermined torque or more, the operation knob 2 is rotated relative to the key cylinder 4. Therefore, the rotating operation by the third party on the operation knob 2 can be suppressed. Further, it is possible to avoid damage to the operation knob 2 and the key cylinder 4 due to the operation knob 2 being forcibly rotated.

  Further, even in the case where the mechanical key K is fixed at the center and a long spring in the radial direction cannot be provided as in the present embodiment, the spring 10 constituting the idling means 3 extends in the rotational axis direction of the operation knob 2. Therefore, the spring 10 having a long overall length can be used, and the urging force applied to the ball 11 can be set larger. Therefore, when the operation knob 2 is rotated when the regular ID code is received, it is possible to avoid the operation knob 2 from being accidentally idle.

  Furthermore, in the present embodiment, the ball 11 and the recess 12 are formed in pairs on the same straight line in the radial direction of the knob portion 2a and the transmission portion 2b. When the operation knob 2 is forcibly rotated at a predetermined torque or more in a state where the movement is restricted, the ball 11 that has been disengaged from one of the recesses 12 is further rotated by 180 °. The other recess 12 is fitted and accommodated.

  Therefore, even when the operation knob 2 is forcibly rotated at a predetermined torque or more while the rotation of the key cylinder 4 is regulated by the regulating means 6, the idle knob portion 2a is stabilized at every 180 °. (The position where the ball 11 is fitted and accommodated in the recess 12), the direction of the protrusion 2aa of the knob 2a (the direction seen from the upper surface) is always kept the same (for example, the state shown in FIG. 1). Therefore, the operability of the operation knob 2 can be maintained.

  By the way, in this embodiment, as shown in FIG. 5, the bulging portion 13 bulging from the edge of the concave portion 12 of the knob portion 2a to the transmission portion 2b side (the front side in the figure) is substantially annular. Is formed. The bulging portion 13 is fitted in the groove 2bb (see FIG. 4) of the knob portion 2a in a state where the transmission portion 2b is assembled to the knob portion 2a, and the knob portion 2a is idled to the transmission portion 2b. The bulging portion 13 is configured not to interfere with the relative rotation.

  As shown in FIG. 6, the bulging portion 13 forms the concave portion 12 deep by the bulging dimension t (that is, the depth h of the concave portion 12 is the depth s from the bottom surface of the knob portion 2a). When the operation knob 2 is forcibly rotated in a state where the rotation of the key cylinder 4 is restricted by the restriction means 6, the ball 11 is fitted into the recess 12. It is possible to suppress an increase in the axial dimension of the ignition switch device while setting a large torque when the engine is disengaged and idling. Therefore, when the operation knob 2 is rotated when the regular ID code is received, it is possible to more reliably avoid the operation knob 2 from being accidentally idle.

  The rotor according to the present embodiment includes a key cylinder 4 having a plurality of tumblers and capable of inserting a regular mechanical key K, and the mechanical key K is integrally formed in the transmission portion 2b. The operation knob 2 also serves as the gripping portion of the mechanical key K, and the operation with the mechanical key K can be performed even when the transmission of the ID code from the transmission means due to the battery running out becomes impossible.

  Further, in the present embodiment, as shown in FIG. 2, the surface of the key cylinder 4 (rotor) facing the transmission portion 2b and the surface of the transmission portion 2b facing the key cylinder 4 are fitted to each other. Possible fitting shapes 17 and 18 are respectively formed. More specifically, as shown in FIG. 7, the operation knob 2 has a fitting shape 17 composed of an oval convex portion on the lower surface (the surface facing the key cylinder 4) of the transmission portion 2b, and a key. As shown in FIG. 8, the cylinder 4 is formed with a fitting shape 18 including a concave portion corresponding to the fitting shape 17 on a surface facing the transmission portion 2 b which is the upper surface thereof.

  However, with the mechanical key K inserted into the key cylinder 4, as shown in FIG. 2, the fitting shape 17 of the convex portion and the fitting shape 18 of the concave portion are matched and fitted in the rotation direction, and these are rotated. It can be linked to the direction. As a result, the strength of the operation knob 2 in the rotational direction can be improved, and the operating force for the knob 2a can be reliably and efficiently transmitted to the key cylinder 4 (rotor) via the transmitter 2b, thereby improving operability. Can be improved.

  Furthermore, in this embodiment, as shown in FIG. 2, it is interposed between the knob 2a and the transmission part 2b, and the knob 2a can be assembled while having a pressing force with respect to the transmission part 2b. An O-ring 19 is provided. That is, as shown in FIG. 9, the operation knob 2 is configured such that an O-ring 19 is interposed between the knob portion 2a and the transmission portion 2b, and the transmission portion 2b is assembled to the knob portion 2a. In this case, the O-ring 19 is not intended to be waterproof, but is mainly intended to assemble the knob portion 2a while having a tightening force on the transmission portion 2b. Instead, it can be set to a very light allowance.

  As described above, according to the present embodiment, the O-ring 19 is provided between the knob and the transmission unit, and can be assembled with the knob while having a pressing force with respect to the transmission unit. It is possible to suppress backlash between the knob 2a and the transmission portion 2b after assembly. Moreover, since play can be suppressed with a general-purpose product such as an O-ring, it is possible to suppress an increase in manufacturing cost.

  Although the present embodiment has been described above, the present invention is not limited to this. For example, a mechanical key is not formed on the operation knob, and a rotating member (rotor) that interlocks with the operation knob instead of the key cylinder. It can also be applied to what has been marked. In this case, for example, the operation knob should be formed integrally with the rotor, but even if an attempt is made to form a separate body for improving rigidity near the center of the operation knob, the spring is operated by the operation knob. Therefore, a spring having a long overall length can be used as the spring constituting the idling means 3.

Also further, idling means 3 in this embodiment is to press the ball 11 in the knob portion 2a side by the urging force of the spring 10, the other pressing means in place of the ball 11 (the roller-shaped or pin-shaped ones Etc.).

The operation knob includes a knob portion having a convex upper portion, and a transmission portion that is separated from the knob portion and can be rotated together with the knob portion to transmit the rotation to the rotor. In addition, the idling means is formed in the transmission part and extends in the rotation axis direction of the operation knob, a pressing means that presses the knob with the urging force of the spring, and the pressing part that is formed in the knob. An ignition switch device having a recess for accommodating the means in a fitted state and having a bulging portion that bulges from the edge of the recess of the knob portion toward the transmitting portion and having a substantially annular shape. Also, the present invention can be applied to ones having different external shapes or those having other functions added.
