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.

With this torque limiter mechanism, when a third party forcibly rotates the operating knob for the purpose of theft or mischief, the operating knob can be rotated idly by rotating the operating knob relative to the rotor. It was possible to prevent a third party from starting the engine illegally.
Japanese Patent Laid-Open No. 2005-1112048

  However, in the above-described conventional ignition switch device, although it is possible to suppress an unauthorized rotation operation on the operation knob by a third party, the third party forcibly pushes the operation knob with an excessive force for the purpose of mischief and the like. When pulled, there is a problem that internal components (such as a rotor) connected to the operation knob are destroyed. In particular, for example, when a mechanical key or the like is integrally extended from the approximate center of the operation knob and applied to the operation knob and the mechanical key that can be removed from the key cylinder as a rotor, the mechanical key is locked to the tumbler of the key cylinder. In this state, if the operation knob is forcibly pulled with an excessive force, the tumbler or the like is destroyed.

  The present invention has been made in view of such circumstances, and even when the operation knob is forcibly pulled with an excessive force, the internal components connected to the operation knob are destroyed. It is an object of the present invention to provide an ignition switch device that can avoid 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. An ignition switch device including a regulating means for canceling the regulation of movement, wherein the mechanical key has a transmission part integrally formed, and the rotor has a plurality of tumblers and is properly The operation knob includes a leaf spring extending toward the transmission portion, and the tip of the leaf spring is in contact with and connected to the transmission portion. The leaf spring is elastically deformed to be disconnected from the transmission portion of the operation knob when the operation knob is prevented from coming off and a tensile load of a predetermined value or more is applied to the operation knob.

  The invention according to claim 2 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. In the ignition switch device having a regulating means for releasing the regulation of the movement, the operation knob has a leaf spring extending to the rotor side, and the tip of the leaf spring is in contact with and connected to the rotor. Is retained by Rukoto, the plate spring to a predetermined value or more tensile load to the operation knob is applied is characterized in that the connection to the rotor of the operation knob is elastically deformed solved.

  According to a third aspect of the present invention, in the ignition switch device according to the first or second aspect, the leaf spring is formed with a rotation restricting portion that restricts the rotation of the operation knob relative to the transmission member or the rotor. In addition, when a load in the rotation direction equal to or greater than a predetermined value is applied to the operation knob, the leaf spring is elastically deformed and the restriction by the rotation restriction portion is released, and the operation knob is attached to the transmission member or the rotor. It is characterized by being able to rotate relatively with respect to the idle.

  According to a fourth aspect of the present invention, in the ignition switch device according to the third aspect, the rotation restricting portion includes a convex portion protruding from the leaf spring with respect to a concave portion formed on a side surface of the transmission member or the rotor. A convex portion is fitted into the concave portion, and the rotation of the operation knob with respect to the transmission member or the rotor is restricted.

  According to the first aspect of the present invention, when a tensile load of a predetermined value or more is applied to the operation knob, the leaf spring is elastically deformed and the connection to the transmission portion of the operation knob is released. Even when pulled to the key cylinder side, only the operation knob is removed while leaving the mechanical key locked to the tumbler and the transmission part integral with the mechanical key on the key cylinder side, and the internal configuration connected to the operation knob It can be avoided that the key cylinder or the like as an element is destroyed.

  In addition, since the elastic deformation of the leaf spring is used to uncouple the operation knob from the transmission portion, a tensile load that can easily uncouple the operation knob from the transmission portion is set with a simple configuration. In addition, the operation knob can be easily applied to a case where there is no allowance in the radial dimension of the operation knob.

  Furthermore, the rotor is composed of a key cylinder having a plurality of tumblers, through which a regular mechanical key can be inserted, and since the mechanical key is integrally formed in the transmission portion, the operation knob also serves as a mechanical key gripping portion. Therefore, even when the ID code cannot be transmitted from the transmitting means due to a battery exhaustion or the like, other operations using the mechanical key can be performed.

  According to the invention of claim 2, when a tensile load of a predetermined value or more is applied to the operation knob, the leaf spring is elastically deformed and the connection of the operation knob to the rotor is released. Even in the case of pulling, only the operation knob is removed, and it is possible to avoid the destruction of the internal components connected to the operation knob.

  Further, similarly to the first aspect, the structure is such that the connection of the operation knob to the transmission portion is released using the elastic deformation of the leaf spring, so that the connection of the operation knob to the transmission portion can be easily released with a simple configuration. Therefore, it can be easily applied to a case where there is no margin in the radial dimension of the operation knob.

  According to the invention of claim 3, the leaf spring is formed with the rotation restricting portion for restricting the rotation of the operation knob relative to the transmission member or the rotor, and the operation knob is loaded with a load in the rotation direction of a predetermined value or more.

  In addition, the leaf spring has both the function of avoiding destruction of internal components by applying an excessive load in the pulling direction and the function of avoiding destruction of internal components by applying an excessive load in the rotating direction. By sharing the leaf spring, it is possible to reduce the number of parts and the manufacturing cost.

  According to invention of Claim 4, a rotation control part consists of a convex part protruded with respect to the recessed part formed in the side surface of the transmission member or the rotor from the leaf | plate spring, a convex part fits into the said recessed part, and the said Since the rotation of the operation knob with respect to the transmission member or the rotor is restricted, the tensile load for releasing the connection of the operation knob to the transmission portion or the rotor can be easily set with a simpler configuration.

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. 7, the ignition switch device according to the present embodiment includes a transmission unit 12 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 13 capable of receiving the ID code from the receiver, and determining means 14 for determining whether or not the ID code received by the receiving means 13 is a registered regular one.

  The transmission means 12 can always transmit an ID code by radio waves or the like. When a driver carrying the transmission means 12 approaches the vehicle and performs a predetermined authentication operation, the reception means 13 including an antenna on the vehicle side or the like. Is configured to receive the ID code. The determination unit 14 compares the ID code registered in advance with the ID code received by the reception unit 13 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. 7, the ignition switch 7 is electrically connected to the engine E (specifically, an ECU that controls the engine E), and when the ignition switch 7 forms a predetermined circuit. 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 means 13 is determined by the determining means 14 to be authentic. 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 14, and 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 disengagement is released. And a solenoid 6a having a plunger 6aa connected to the base end 6ba of the arm 6b.

  If the determination means 14 determines that the ID code received by the receiving means 13 is authentic, the solenoid 6a is energized, and the energization attracts the plunger 6aa and moves downward in the figure. 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 FIGS. 3 to 5, the operation knob 2 in the present embodiment includes a knob portion 2 a having an upper portion formed in a convex shape 2 aa and an accommodation space 2 b formed inside the knob portion 2 a. Accommodates the transmission part 3 in a state in which the mechanical key K is extended downward. The mechanical key K is integrally formed with the transmission portion 3 by, for example, insert molding, and is firmly fixed by a spring pin P or the like.

  In addition, a plurality of leaf springs 10 (in this embodiment, leaf springs 10 extending from four directions) extending from the accommodating space 2b of the operation knob 2 to the transmission portion 3 side are formed. The transmission part 3 is located between 10. A bent portion 10a is formed at the tip of the leaf spring 10 by bending toward the inside, and the bent portion 10a is in a natural state in which no load is applied to the leaf spring 10 (the leaf spring 10 is elastically deformed). In such a state, the dimension reaches the lower surface of the transmission portion 3 in a state where the transmission is not performed.

  As a result, the leaf spring 10 embraces and connects the transmitting portion 3 at the bent portion 10a, and the transmitting portion 3 is connected to the bent portion 10a until a predetermined load to be elastically deformed is applied to the leaf spring 10. Since it is avoided that it interferes and separates from the operation knob 2, it is possible to prevent the transmission part 3 from coming off from the operation knob 2. Thus, the transmission unit 3 is an integral part of the operation knob 2, and the transmission unit 3 rotates as the operation knob 2 is rotated, and the key cylinder 4 can be rotated via the mechanical key K. The

  Further, the plate spring 10 is elastically deformed in the diameter increasing direction (a direction away from the transmission portion 3) when a tensile load of a predetermined value or more is applied to the operation knob 2, and the connection of the operation knob 2 to the transmission portion 3 is released. It has come to be. That is, when the operation knob 2 is pulled upward in the drawing in the state where the mechanical key K as shown in FIG. 2 is locked to the tumbler of the key cylinder 4, the lower surface of the transmission portion 3 interferes with the bent portion 10a, When the tensile load reaches a predetermined value, the bent portion 10a is pushed outward and the leaf spring 10 is elastically deformed outward so that the connection is released.

  Thereby, in a state where the rotation of the key cylinder 4 is regulated by the regulating means 6 (a state where the tumbler locks the mechanical key K), the operation knob 2 is forcibly pushed with an excessive force for the purpose of mischief or the like by a third party. Even when pulled, only the operation knob 2 is removed while leaving the mechanical key K locked to the tumbler and the transmission part 3 integral with the mechanical key K on the key cylinder 4 side. It is possible to avoid the destruction of the key cylinder 4 or the like, which is an internal component.

  Furthermore, each of the leaf springs 10 is formed with a convex portion 11 as a rotation restricting portion that restricts the rotation of the operation knob 2 with respect to the transmission member 3, and the operation knob 2 has a rotation direction greater than a predetermined value. When the load is applied, the leaf spring 10 is elastically deformed and the restriction by the convex portion 11 is released, and the operation knob 2 can rotate relative to the transmission member 3 to rotate freely. Yes.

  Specifically, as shown in FIG. 6, the convex portion 11 as the rotation restricting portion is configured to protrude from the leaf spring 10 to the concave portion 3 b formed on the side surface of the transmission member 3. The convex part 11 is fitted to 3b, and the rotation of the operation knob 2 with respect to the transmission member 3 is restricted. Then, in a state where the rotation of the key cylinder 4 is restricted by the restricting means 6, when a load in the turning direction of a predetermined value or more is applied to the operation knob 2, the convex portion 11 rides on the concave portion 3 b and the leaf spring 10 Since it is elastically deformed outward, the restriction on the rotation of the operation knob 2 is released, and the operation knob 2 rotates relatively with respect to the transmission member 3 to rotate idle.

  Therefore, even when an excessive load is applied to the operation knob 2 in the rotation direction (operation direction) in a state where the rotation of the key cylinder 4 is restricted by the restriction means 6, the operation knob 2 is idled. As a result, it is possible to prevent an excessive load from being transmitted to the transmission unit 3 and the mechanical key K, so that the internal components (such as the key cylinder 4 in this embodiment) connected to the operation knob 2 are destroyed. Can be avoided. Further, according to the present embodiment, the leaf spring 10 has a function of avoiding destruction of internal components (such as the key cylinder 4) by applying an excessive load in the pulling direction and an internal configuration by applying an excessive load in the rotating direction. It also has a function of avoiding destruction of elements (such as the key cylinder 4), and by combining these functions with the leaf spring 10, it is possible to reduce the number of parts and the manufacturing cost.

  In addition, since the recessed part 3b formed in the side surface of the transmission part 3 is made into the groove shape extended to an up-down direction, when the excessive load of a tension | pulling direction is provided with respect to the operation knob 2, the convex part 11 It is set so that it will simply slide along the groove shape and will not run over from the recess 3b. Accordingly, when an excessive load in the pulling direction is applied to the operation knob 2, no load is applied when the convex portion 11 rides up from the concave portion 3b.

  According to the above-described embodiment, since the elastic deformation of the leaf spring 10 is used to uncouple the operation knob 2 from the transmission portion, the operation knob 2 with respect to the transmission portion 3 can be easily configured. It is sufficient to set a tensile load for releasing the connection, and it is sufficient to slightly elastically deform the leaf spring in the radial direction of the operation knob 2 until the bent portion 10a does not interfere with the transmission portion 3. The present invention can be easily applied to a case where the knob 2 has no sufficient radial dimension.

  Furthermore, since the mechanical key K is integrally formed in the transmission portion 3 while the key cylinder 4 having a plurality of tumblers and capable of inserting the regular mechanical key K is used as the rotor, the operation knob 2 is attached to the mechanical key K. Even when the gripping part is also used and the ID code cannot be transmitted from the transmitting means 12 due to battery exhaustion or the like, other operations by the mechanical key K (operations other than the engine starting operation, for example, formed in the fuel tank) It is possible to release the lock on the lid of the fuel filler opening.

  On the other hand, as shown in FIG. 5, the transmission portion 3 according to the present embodiment has an upper surface edge portion (surface edge located in the mounting direction with respect to the operation knob 2) as a tapered surface 3 a. Thereby, when the transmission part 3 is assembled to the operation knob 2, the tapered surface 3 a can be elastically deformed in a direction in which the bent part 10 a is pressed and the leaf spring 10 is expanded. Assembling workability can be improved.

  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, the operation knob has a leaf spring extending to the rotor side as in the above embodiment, and the tip of the leaf spring is in contact with and connected to the rotor to prevent the operation knob. When a tensile load of a predetermined value or more is applied to the plate spring, the leaf spring is elastically deformed to disconnect the operation knob from the rotor.

  According to the other embodiment described above, when a tensile load of a predetermined value or more is applied to the operation knob, the leaf spring is elastically deformed and the connection of the operation knob to the rotor is released. Even when it is pulled, only the operation knob is removed, and it is possible to avoid destruction of the internal components (rotor) connected to the operation knob. Further, similarly to the above-described embodiment, the configuration is such that the connection of the operation knob to the transmission portion is released using the elastic deformation of the leaf spring, so that the connection of the operation knob to the transmission portion can be easily released with a simple configuration. Therefore, it can be easily applied to a case where there is no margin in the radial dimension of the operation knob.

  Further, in the other embodiment, as in this embodiment, the leaf spring is formed with a rotation restricting portion for restricting the rotation of the operation knob with respect to the rotor, and the operation knob is rotated more than a predetermined value. When a load in the moving direction is applied, the leaf spring is elastically deformed so that the restriction by the rotation restricting portion is released, and the operation knob can be rotated relative to the transmission member to be idle. Can do. Even in this case, when an excessive load is applied in the rotation direction (operation direction), it is possible to avoid the destruction of the internal component (rotor) connected to the operation knob. .

  Furthermore, in the other embodiment, as in the present embodiment, the rotation restricting portion is composed of a protruding portion that protrudes from the leaf spring to the recessed portion formed on the side surface of the rotor. And the rotation of the operation knob with respect to the rotor can be restricted. Even in this case, it is possible to set the tensile load for releasing the connection of the operation knob to the rotor with a simpler configuration.

  In the present embodiment, the rotation restricting portion including the convex portion 11 is formed on the leaf spring 10. However, the rotation restricting portion may be provided in a part different from the leaf spring 10 or the rotation restricting portion. It is good also as what gave only the destruction avoidance function of an internal component by abbreviate | omitting and applying the excessive load of the pull direction with respect to an operation knob.

  The tip of the leaf spring of the operation knob is prevented from coming off by being in contact with and connected to the transmission portion or the rotor, and when a tensile load of a predetermined value or more is applied to the operation knob, the leaf spring is elastically deformed and the operation knob As long as the ignition switch device is disengaged from the transmission unit or the rotor, the ignition switch device can be applied to a device having a different external shape or a device to which another function is added.
