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 described above, since the spring is extended in the radial direction with respect to the operation knob, when it is attempted to provide a predetermined component at the center of the operation knob, the spring extends over the radial direction. Since it is difficult to provide a spring with a long overall length and a large urging force, the click ball is pressed against the concave portion with a spring with a short overall length and a small urging force, and the control knob rotates even with a relatively small torque. It is. 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.

  In addition, when the click ball constituting the idling mechanism is formed symmetrically on the operation knob, when the operation knob is idling to rotate forcibly, when the operation knob is idling, when it is rotated 360 °, When the click ball is fitted and the operation knob is held at that position, the initial position is different from the predetermined position. However, when the operation knob is printed to indicate the operation method or the operation knob has an asymmetric shape with respect to the rotation axis direction, the operation method becomes difficult to understand.

  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 another object of the present invention to provide an ignition switch device that can re-engage the pressing means with the concave portion at the initial position when the operating knob rotates idly when the operating knob is forced to rotate.

  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 shaft that is allowed to start the engine, and the rotation of the shaft are restricted, and the rotation of the shaft is performed on the condition that the ID code received by the receiving means is determined to be normal by the determining means. A regulating means for canceling the regulation of movement, and when the turning of the shaft is regulated by the regulating means and the manipulation knob is rotated with an operation force of a predetermined torque or more, the manipulation knob is In the ignition switch device including the idling means for idling by rotating relative to the shaft, the idling means is formed in a connecting portion of the shaft with the operation knob, and the rotation axis direction of the shaft An urging means capable of urging the operation knob, a plurality of pressing means for pressing the connecting portion of the operation knob with the shaft by the urging force of the urging means, and the pressing means formed on the operation knob. The ignition switch device according to claim 1, wherein the ignition switch device has a concave portion that is housed in a combined state, and the concave portion is formed on different concentric circles with respect to the rotation shaft of the operation knob.

  According to a second aspect of the present invention, in the ignition switch device according to the first aspect, the external appearance of the operation knob is asymmetric with respect to the rotational operation direction.

  According to a third aspect of the present invention, in the ignition switch device according to the first or second aspect, the pressing means and the concave portion are formed in the same linear shape in the radial direction of the operation knob and the shaft, respectively. It is characterized by.

  According to the first aspect of the present invention, the idling means is formed in a connecting portion of the shaft with the operation knob and can be biased in the direction of the rotation axis of the shaft, and the biasing force of the biasing means. Since it has a plurality of pressing means for pressing the connecting portion with the shaft in the operation knob and a recess formed in the operation knob and accommodating the pressing means in a fitted state, when a regular ID code is received When the operation knob is rotated, it can be avoided that the operation knob is accidentally idle. Furthermore, since the recess is formed on concentric circles that are different from each other with respect to the rotation axis of the operation knob, when the operation knob rotates idly to forcefully rotate the operation knob, the pressing means is again set to the recess at the initial position. Can be fitted.

  According to the invention of claim 2, since the appearance of the operation knob is asymmetric with respect to the rotation operation direction, the operation knob can have an appearance with improved operability according to the mounting position of the operation knob. At the same time, when the operating knob rotates idly to forcefully rotate the operating knob, it can be re-fitted at the initial position.

  According to the invention of claim 3, since the pressing means and the concave portion are formed in the same straight line in the radial direction of the operation knob and the shaft, respectively, the holding state of the operation knob can be stably performed. At the same time, 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 does not fit into the other recess, and further rotates the operating knob by 360 °. Thus, the original recess is fitted.

The top view which shows the connection part with the operation knob in the shaft of the ignition switch device The rear view which shows the connection part with the shaft in the operation knob of the ignition switch device The block diagram which shows the whole schematic structure of the ignition switch device

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 to 5, the ignition switch device main 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. 6, the ignition switch device according to the present embodiment includes a transmission unit 11 that can be carried by the driver and can transmit a vehicle-specific ID code, and a transmission unit 11 disposed on the vehicle side. Receiving means 12 capable of receiving the ID code from the receiving means, determining means 13 for determining whether or not the ID code received by the receiving means 12 is a registered regular one, and the rotation of the shaft 3 is restricted. In addition, there is a restricting means 14 for canceling the restriction of the rotation of the shaft 3 on the condition that the ID code received by the receiving means 12 is determined to be proper by the determining means 13.

  The transmission means 11 can always transmit an ID code by radio waves or the like. When a driver carrying the transmission means 11 approaches the vehicle and performs a predetermined authentication operation, the reception means 12 including a vehicle-side antenna or the like. Is configured to receive the ID code. The determination unit 13 compares the ID code registered in advance with the ID code received by the reception unit 12 and determines that the regular ID code has been received if they match. Thus, if the determination means 13 determines that the legitimate ID code has been received, the restriction by the restriction means 14 is released and the operation knob 2 can be rotated, while the legitimate ID code is If it is not received, the turning of the operation knob 2 is restricted by the restricting means 14.

  The operation knob 2 is formed of a knob-like member that can be rotated by the driver, and is rotatable about the axis L (the axis of the shaft 3). The shaft 3 is connected to the operation knob 2 via springs 9a and 9b as urging means constituting a torque limiter means, which will be described later, and steel balls 10a and 10b as pressing means, so that the operation knob 2 can be rotated. Accordingly, the vehicle can be rotated about the axis L to start the engine of the vehicle. Specifically, as shown in FIG. 1, the shaft 3 is connected to the connecting shaft 4 at the lower end thereof, and is configured to operate the movable member 6 and the lock bar R via the connecting shaft 4. ing.

  Then, for example, when the operation knob 2 is pressed from the off position to the steering lock position, the lock bar R is in a protruding state to be engaged with a handlebar (not shown) of the two-wheeled vehicle, and the handlebar is When the operation knob 2 is rotated from the off position to the on position while being locked, the movable contact 6a operates as the movable member 6 rotates, and can come into contact with and separate from the fixed contact 7. Note that reference numeral 8 in FIG. 1 denotes a sensor that detects that the shaft 3 moves downward in the drawing in accordance with the pressing operation of the operation knob 2.

  The movable member 6, the movable contact 6 a and the fixed contact 7 constitute the ignition switch 5. As shown in FIG. 6, the ignition switch 5 is electrically connected to the engine E (specifically, an ECU that controls the engine E). When the ignition switch 5 forms a predetermined circuit, The engine E can be started. When the start button (not shown) separately provided is pressed in a state where the engine E can be started, the engine E is started. That is, if the shaft 3 and the interlocking shaft 4 are rotated by rotating the operation knob 2, the ignition switch 5 is electrically turned on and the engine of the motorcycle can be started.

  On the other hand, the restricting means 14 is disposed in the ignition switch device body 1 and is electrically connected to the determining means 13. For example, the restricting means 14 is engaged with a notch formed in the shaft 3 or the interlocking shaft 4. And a solenoid having a plunger connected to a proximal end of the arm and a swinging arm between a position where the arm is engaged and a position where the engagement is released. When the determination unit 13 determines that the ID code received by the reception unit 12 is authentic, the solenoid is energized, and the plunger is sucked and moved by the energization. The base end of the shaft 3 is also pushed down, the arm swings, and the distal end is separated from the notch of the shaft 3 or the interlocking shaft 4, so that the lock for the rotation operation of the shaft 3 is released. In this state, if the operation knob 2 is turned to the on position, the ignition switch 5 is turned on and the engine E is started.

  Here, as shown in FIGS. 2 to 5, the operation knob 2 in the present embodiment includes a knob portion 2 a whose upper portion is formed in an asymmetrical convex shape, and a display portion formed in a part of the knob portion 2 a. 2b, a connecting portion 2c formed in a concave shape to be connected to the shaft 3, and idle means comprising springs 9a and 9b, steel balls 10a and 10b, and recessed portions 2ca and 2cb. The operation knob 2 is connected and fixed to the connecting portion 3a of the shaft 3 with a spring pin.

  The knob 2a of the operation knob 2 is formed so that the convex shape of the upper part extends substantially linearly and is easy for the driver to pick, and the appearance is asymmetric with respect to the rotation operation direction (left and right direction in the figure). It is said that. Further, the operation knob 2 is formed with a connecting portion 2cb for connecting to the shaft 3, and idle means as a torque limiter is formed in the connecting portion 2cb and the connecting portion 3a for connecting the operating knob 2 of the shaft 3.

  The springs 9a and 9b as urging means are formed in the connecting portion 3a of the shaft 3 with the operation knob 2 and can be urged in the direction of the rotation axis L of the shaft 3 (upward in FIG. 3). Are accommodated in the accommodating holes 3aa and 3ab formed in the connecting portion 3a. The steel balls 10a and 10b as pressing means press the connecting portion 2c of the operation knob 2 with the shaft 3 by the urging force of the springs 9a and 9b, and two steel balls 10a and 10b are formed in this embodiment.

  The recesses 2ca and 2cb are formed in the operation knob 2 and accommodate the steel balls 10a and 10b in a fitted state. Specifically, as shown in FIG. It consists of a pair of concave shape formed in the connection part 2c with 3. As shown in FIG. However, it is configured that the shaft 3 can be rotated together with the operation knob 2 when the operation knob 2 is rotated with the restriction by the restricting means 14 being released.

  Further, when the rotation of the shaft 3 is restricted by the restricting means 14 and the operation knob 2 is forcibly turned with an operation force of a predetermined torque or more, the steel balls 10a and 10b with respect to the recesses 2ca and 2cb are operated. It is constituted so that the fitting of can be removed and idle. That is, when the knob portion 2a is forcibly rotated with an operation force equal to or greater than a predetermined torque, the steel balls 10a and 10b ride on the recesses 2ca and 2cb, and the fitting force of the steel balls 10a and 10b to the recesses 2ca and 2cb is released. Therefore, the operation knob 2 rotates relative to the shaft 3 and rotates idle. Note that reference numerals 2 cc and 2 cd in FIG. 5 indicate ridges continuous with the recesses 2 ca and 2 cb.

  Accordingly, when the rotation of the shaft 3 is restricted by the restricting means 14 and an attempt is made to forcibly rotate with an operation force equal to or greater than a predetermined torque, the operation knob 2 is rotated relative to the shaft 3. It is possible to prevent the rotation of the operation knob 2 by a third party by making it idle. Further, it is possible to avoid damage to the operation knob 2 and the shaft 3 caused by forcibly turning the operation knob 2.

  Furthermore, in the present embodiment, the springs 9a and 9b constituting the idling means are extended in the direction of the rotation axis L (vertical direction) of the operation knob 2, so that the springs 9a and 9b having a long overall length are used. The urging force applied to the steel balls 10a and 10b 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 recesses 2ca and 2cb are respectively formed on two concentric circles (Ra and Rb) different from each other with respect to the rotation axis L of the operation knob 2, as shown in FIG. . Accordingly, the recesses 2ca and 2cb are formed on concentric circles different from each other with respect to the rotation axis L of the operation knob 2 (Ra and Rb which are virtual circles centered on the rotation axis L). When the operation knob 2 is rotated in an attempt to rotate the knob 2, the steel ball 10a is fitted into the recess 2cb or the steel ball 10b is fitted into the recess 2ca even if the operation knob 2 is rotated 180 °. And can be fitted again at the initial position rotated 360 °.

  That is, when two (three or more) steel balls 10a and 10b are formed on one circle (virtual circle) with respect to the rotation axis L, the operation knob 2 is forcibly rotated. When the operation knob 2 is rotated idly, when the operation knob 2 is rotated 180 °, the steel ball 10a is fitted into the recess 2cb, and the steel ball 10b is fitted into the recess 2ca. Will be held. However, when the operation part 2 is printed on the display 2b of the operation knob 2 to indicate the operation method or the initial position, or when the operation knob 2 has an asymmetric shape with respect to the rotation axis L direction, the operation method can be understood. In contrast to the problem that it becomes difficult, according to the present embodiment, the problem can be solved.

  Still further, the steel balls 10a and 10b and the recesses 2ca and 2cb are respectively formed in pairs in the same straight line in the radial direction of the operation knob 2 and the shaft 3 (left and right direction in FIGS. 4 and 5). As a result, the holding state of the operation knob 2 can be stably performed, and when the operation knob 2 is forcibly rotated at a predetermined torque or more, the steel ball that has been disengaged from one recess is Without fitting into the other recess, the operation knob 2 is further rotated 360 ° to be fitted into the original recess.

  According to the present embodiment, since the appearance of the operation knob 2 is asymmetrical with respect to the rotation operation direction, the appearance of the operation knob 2 can be improved according to the mounting position of the operation knob 2 and the like. At the same time, when the operation knob 2 rotates idly to forcefully rotate the operation knob 2, the springs 10a and 10b can be fitted again into the recesses 2ca and 2cb, respectively, at the initial position.

  Although the present embodiment has been described above, the present invention is not limited to this. For example, instead of the springs 9a and 9b, another form of urging means (for example, a leaf spring or resin) may be used, or steel. Instead of the balls 10a and 10b, other forms of pressing means (such as pin-like members) may be used. In this embodiment, two pressing means (steel balls) and two urging means (springs) are formed, but three or more may be formed. However, even in that case, the recesses are formed on different concentric circles with respect to the rotation axis of the operation knob (even if a plurality of recesses are formed on one concentric circle, the recesses are formed on the other concentric circles. Furthermore, it is sufficient if a recess is formed).

  The idling means is formed at a connecting portion of the shaft with the operation knob and can be biased in the direction of the rotation axis of the shaft, and the connecting portion of the operation knob with the shaft by the biasing force of the biasing means. A plurality of pressing means for pressing, and idle means having a recess formed in the operation knob and accommodating the pressing means in a fitted state, and the recesses are mutually connected with respect to the rotation axis of the operation knob. As long as the ignition switch device is formed on different concentric circles, it can be applied to devices having different external shapes or those having other functions.
