Description

  The present invention relates to a switch device suitable for starting an engine of a vehicle, for example.

In recent years, in vehicles such as four-wheeled vehicles, a user who has an appropriate electronic key in the driver's seat is assumed to be equipped with an authentication system such as an immobilizer instead of the conventional operation of inserting a key into a key cylinder and turning it. Vehicle types in which an engine is started simply by pressing a push button of a provided engine start switch device are becoming popular.
There exists a thing shown by patent document 1 as an engine starting switch apparatus as mentioned above. This is provided with a coil antenna used in an emergency such as when the battery of the electronic key is exhausted on the outer periphery of the front end (around the push button). The decorative cylinder surrounding the outer periphery of the coil antenna is decorated only on the design surface exposed on the front surface, and the other portions are not subjected to the decorative plating and make it easy to transmit radio waves from the coil antenna. A transmission part is formed.

In the assembled state of the switch device 10, the range of movement of the slider 16 and the push button 13 integrated therewith is a predetermined range by the contact between the front and rear inner end surfaces of the stopper opening 16c and the upper end of the stopper portion 17b. Is regulated. The predetermined range is a range from the position in the neutral state (non-operating state) shown in FIG. 3 to the position in the full stroke state shown in FIG.

  In addition, a pressing operation unit, which will be described later, is inclined with respect to a predetermined direction (in this case, the front-rear direction) in which the slider 16 moves to a left position (a front position of the left stopper opening 16c) on the upper surface of the plate-like portion 16b. Inclined surfaces 35 and 36 that can contact 41a and 42a are formed (see FIG. 3). The inclined surfaces 35, 36 are formed side by side, the front inclined surface 35 contacts the pressing operation portion 41 a of the front switch body 41, and the rear inclined surface 36 is the pressing operation portion of the rear switch body 42. It is the structure which contacts 42b. Here, the inclined surface 35 is a forward inclined surface that is inclined downward toward the rear and is inclined in a direction in which the pressing operation portion 41 a is retracted when the switch device 10 is operated. On the other hand, the inclined surface 36 is an upwardly inclined surface that is inclined upward and is inclined in the direction in which the pressing operation portion 42a is advanced when the switch device 10 is operated.

Further, as shown in FIGS. 1B and 5, a concave chamber 16 d in which the return spring 18 is disposed is formed on the lower surface side of the center position in the left-right direction at the rear end portion of the plate-like portion 16 b of the slider 16. Yes. A protrusion 16e (shown in FIG. 5, omitted in FIG. 1 and the like) protruding rearward is formed on the inner end surface in front of the concave chamber 16d. The tip of the return spring 18 is positioned and held by being mounted on the outer periphery of the protrusion 16e.
As shown in FIG. 5, a boss portion 16 f that protrudes upward is formed at the center position in the left-right direction on the relatively front side of the plate-like portion 16 b of the slider 16. A cylindrical concave chamber 16g that opens to the lower surface side is formed in the boss portion 16f. As shown in FIG. 5, a moderation feeling spring 19 and a moderation feeling ball 20 are sequentially placed in the cylindrical concave chamber 16g. It is loaded.

  The lower plate 17 is a molded product of synthetic resin, and is a member that is attached to the lower surface of the first case 11 from below and integrated with the first case 11 as shown in FIGS. 5 and 7. The lower plate 17 can be attached to and detached from the first case 11 only when the return spring 18 and the slider 16 are assembled to the first case 11 (however, the second case 12 is removed). It is a simple configuration. Further, when viewed from the lower surface, the lower plate 17 has a substantially T-shaped outer shape as a whole, with the central portion in the left-right direction extending elongated forward and the rear end portion extending left and right. The upper surface side of the front end portion extending forward of the lower plate 17 is fitted into the opening 11d of the first case 11 described above, and the upper surface constitutes a ball contact portion 17a that contacts the moderation sensation ball 20. Moreover, as shown in FIG. 3, the stopper part 17b fitted in the opening 11e of the 1st case 11 mentioned above is formed in the left and right both ends of the rear end part of the lower plate 17 in two places in total.

  As described above, the return spring 18 is a coil spring mounted between the rear portion of the slider 16 and the partition wall 11f of the first case 11, and moves the slider 16 toward the non-operation position (in this case, forward). It functions as a biasing member that biases.

  The moderation sensation generating mechanism 21 includes the moderation sensation spring 19, the moderation sensation ball 20, and the ball contact portion 17a. The moderation sensation ball 20 is always pressed downward by the urging force of the moderation sensation spring 19 and is pressed against the upper surface of the ball contact portion 17a. The moderation sensation ball 20 moves in the front-rear direction together with the slider 16, but the ball contact portion 17a is integrated with the first case 11 and does not move. Further, although the upper surface of the ball contact portion 17a has a generally ridge-like shape, in the neutral state in which the push button 13 and the slider 16 are in the non-operating position (shown in FIGS. 3 and 5), a moderation sensation is provided. The ball 20 is in pressure contact with a position slightly ahead of the most raised top position on the upper surface of the ball contact portion 17a (see FIG. 5). When the slider 16 moves from a non-operating position beyond a predetermined operating position, the moderation sensation ball 20 needs to get over the top position of the ball contact portion 17a while compressing the moderation sensation spring 19. At this time, a resistance force is generated in the slider 16 as much as the moderation feeling spring 19 needs to be compressed, and this resistance force causes a moderation feeling. The shape of the upper surface of the ball contact portion 17a is set so that the magnitude of the resistance force reaches a peak (maximum) at a position slightly ahead of the above-described operating position, for example.

  The connector 31 is a connector for electrically connecting the switch device 10 and an external device (for example, a vehicle engine control controller or an immobilizer vehicle-mounted controller). The connector 31 and a predetermined circuit conductor on the circuit board 40 are connected to each other with L-shaped terminals (extending from the front end of the connector 31 with the tip extending through the circuit board 40) as indicated by reference numerals 31a and 31b in FIG. Is inserted into the hole and soldered).

  As described above, the coil antenna 32 has a coil wire (conductive wire whose surface is insulated) on the outer periphery (between the front wall portion 14b and the rear wall portion 14c) of the outer cylindrical portion 14a of the front component member 14. It is configured by winding, and is connected to a predetermined circuit conductor of the circuit board 40 via the coil terminal 33 described above. This coil antenna 32 is used when normal wireless communication for verification check between the electronic key and the antenna of the immobilizer in-vehicle controller cannot be performed because the battery of the immobilizer electronic key is exhausted. This is an emergency antenna. That is, when the user brings the electronic key near the push button 13 (that is, near the coil antenna 32), the electronic key is activated by the power transfer by the electromagnetic wave transmitted from the coil antenna 32. Wireless communication for collation confirmation is executed with the coil antenna 32. If the collation result is affirmative, engine start is permitted.

The circuit board 40 is mounted with the switch main bodies 41 and 42 and the like, and a drive circuit for the coil antenna 32 and the like may be formed on the board 40. The circuit board 40 is disposed so as to close the upper surface of the first case 11 in a posture in which the substrate surface is parallel to the front-rear direction and orthogonal to the up-down direction. It is fixed to the connector 31.
In addition, what is shown with the code | symbol 37 in FIG. 5 etc. is the light emission part which consists of a light emitting element mounted in the front lower surface side of the circuit board 40. FIG. The light emitting unit 37 is for illuminating the push button 13 by irradiating the push button 13 with light from the back side and notifying the user of information such as the position of the push button 13.

Each of the switch bodies 41 and 42 has pressing operation portions 41a and 42a (shown in FIG. 3) that can move forward and backward so as to appear and that are urged in a forward direction (in this case, a downward projecting direction). This is a module type switch having a built-in switch contact that is switched on and off by the forward and backward movement of the pressing operation parts 41a and 42a, and is called a so-called detection switch (or may be called a micro switch). These switch bodies 41 and 42 have, for example, three contact terminals A, B, and C. When the pressing operation portions 41a and 42a are not pushed in, the common terminal C and the normally closed terminal B are in an inoperative state. When the pressing operation portions 41a and 42a are pushed in by a predetermined amount or more, the common terminal C and the normally open terminal A are in an operating state. In this case, the vehicle engine start controller or the like connected to the switch device 10 via the connector 31 reads such a contact switching operation of the switch bodies 41 and 42 and determines that the engine start or stop has been commanded. To do.
In this case, the switch bodies 41 and 42 are mounted on the lower surface side of the circuit board 40 as shown in FIG. 3, and are installed so that the forward and backward directions of the pressing operation portions 41a and 42a are in the vertical direction intersecting the front-rear direction. Is done.

Here, in the neutral state in which the push button 13 and the slider 16 are in the non-operation position (shown in FIG. 3), the pressing operation portion 41 a of the switch body 41 is in a state of being advanced to the maximum without being pressed against the inclined surface 35 described above. (In other words, when the push button 13 or the slider 16 is pushed rearward from the non-operation position, the push button 13 or the slider 16 is pressed backward to move backward. When the push button 13 or the slider 16 is pushed to the operating position, the contact state of the switch body 41 is retracted to a position where the switch body 41 switches from the non-operating state to the operating state. It is the composition to do.
Further, in the neutral state described above, the pressing operation portion 42a of the switch body 42 is in a state of being maximally retracted by being pressed against the above-described inclined surface 36 (that is, a state in which the pressing operation portion 42a is pushed upward to the maximum, and a contact is in an operating state). When the push button 13 or the slider 16 is pushed backward from the non-operation position, the forward movement is started while being pressed against the inclined surface 36 (that is, the forward movement starts to protrude downward), and the push button is started. When the slider 13 or the slider 16 is pushed to the operating position, the contact state of the switch body 42 is advanced to a position where the operating state is switched from the operating state to the non-operating state.

In the switch device 10 described above, in the neutral state where the user does not press the push button 13, the slider 16 is moved to the non-operating position (the upper end portion of the stopper portion 17b is the stopper) as shown in FIG. Since the switch body 41 is inactive and the switch body 42 is in operation, the vehicle engine start or stop command is not output. (That is, the controller does not determine that such a command has been output).
When the user performs an operation of pushing the push button 13 backward against the urging force of the return spring 18 or the resistance force of the moderation generating mechanism 21, and the push button 13 or the slider 16 is pushed after the operating position, each inclined surface 35 and 36 are in contact with the pressing operation portions 41a and 42a of the switch bodies 41 and 42 to move the pressing operation portions 41a and 42a forward and backward as described above, and the switch contacts of the switch bodies 41 and 42 are turned on and off. Are switched (in this case, the switch main body 41 is in an operating state and the switch main body 42 is in an inactive state), so that a command for starting or stopping the engine of the vehicle is output (that is, such a command is output). The controller side will determine).

Note that when the user performs an operation of pushing the push button 13 backward, normally, the push button 13 or the slider 16 temporarily moves to the full stroke. In this full stroke state, the upper end portion of the stopper portion 17b comes into contact with the front inner end surface of the stopper opening 16c, thereby preventing the push button 13 and the slider 16 from moving further rearward.
On the in-vehicle controller side, the command may be determined based on the AND condition of the contact operation of each switch body 41, 42, or may be determined based on the OR condition. That is, it may be determined that a command has been issued when the state of both the contacts of each switch body 41, 42 (specifically, the state of a signal such as a voltage corresponding to the state of the contact) has changed appropriately. Alternatively, it may be determined that a command has been issued when the state of the contact of either one of the switch bodies 41 and 42 has changed appropriately. However, when one of the switch main bodies 41 and 42 fails, in order to ensure that the engine start can be commanded reliably, when the contact state of either one of the switch main bodies 41 or 42 changes appropriately. In other words, in this case, it is desirable to determine that there is a command when the contact of the switch body 41 is changed from the non-operation state to the operation state, or when the contact of the switch body 42 is changed from the operation state to the non-operation state.
As described above, according to the switch device 10, an engine start or stop command can be output with high reliability by the two switch bodies 41 and 42.

Moreover, in the switch device 10 of the present example, the decorative thin film applied to the design surface of the front outer peripheral member 15 that is a decorative member is the non-conductive thin film 15b. Does not interfere with output radio waves. For this reason, the communication failure of the coil antenna 32 by a radio wave being obstruct | occluded by the design surface of a decoration member can be prevented.
Further, the outer periphery of the front surface of the switch device 10 (around the push button 13) is decorated with the non-passing thin film 15b, so that the decorativeness is enhanced and the position of the push button 13 can be clearly shown to the user. Further, the decorative member forming the non-passing thin film 15b is a member (front outer peripheral member 15) that is separate from the complex-shaped front part member 14 that functions as the bobbin 25 of the coil antenna 32. There is also an effect that the process of forming is facilitated.

  In addition, this invention is not restricted to the said Example, There can be various deformation | transformation and application. For example, there may be a mode in which the front component member 14 functions as the decorative member of the present invention. That is, for example, the front surface of the front component 14 may be decorated with the front surface of the front wall portion 14b as a design surface and a non-conductive thin film formed on the front surface. However, since the front component member 14 is a member having a complicated shape that functions as the bobbin 25 of the coil antenna 32, the process of forming the non-conducting thin film becomes relatively troublesome, and the coil wire of the coil antenna 32 is routed. Since the wound member and the decorative member forming the non-conducting thin film are the same product, there is a disadvantage that productivity is lowered. On the other hand, as in the above-described embodiment, the front outer peripheral member 15 having a relatively small and simple shape separate from the front component member 14 is used as a decorative member, and a non-conductive thin film is formed on the front outer peripheral member 15. In the decoration mode, the process of forming the non-conductive thin film becomes relatively simple, and the process of winding the coil wire of the coil antenna 32 and the process of forming the non-conductive thin film are separate parts. There is an advantage that productivity is improved by increasing the degree of freedom in the production process such that these processes can be executed separately.
