Description

  The present invention relates to a switch device used for an engine start switch of a vehicle, and more particularly to a switch device in which a coil antenna is provided on an operation member that can be pushed.

  Conventionally, in a vehicle, a driver carries a portable device that transmits and receives ID information instead of a mechanical key, performs authentication by performing wireless communication between the portable device and the vehicle, and starts the engine when authentication is established. There are known systems that make it possible. In this system, the engine is started by a push operation of an engine start switch as a switch device provided in the driver's seat of the vehicle.

  The engine start switch accommodates an operation member capable of push operation and a substrate on which a push switch driven by a push operation of the operation member is mounted in a substantially cylindrical housing. Here, when the battery of the portable device is dead or the voltage is lowered, wireless communication cannot be performed between the portable device and the vehicle, and therefore the engine cannot be started. To prevent this, the engine start switch has a built-in coil antenna on the front side of the operation as an emergency communication means. By bringing the portable device closer to the engine start switch, the coil antenna does not contact the portable device. In addition, power can be supplied and communication can be performed. As such an engine start switch, for example, there is one as disclosed in Patent Document 1.

When the driver performs a push operation toward the back side, the push switch 30 of the board 3 is pressed, and the engine is started.

  The housing 1 is composed of three members, that is, a base member 10 that houses the substrate 3 and the like, and an intermediate member 12 that is substantially covered by the surface side member 11 and the base member 10 in addition to the surface side member 11. The shape is substantially cylindrical.

  The operation member 2 is configured so as to cover the operation front side of the operation unit main body 20 that presses the push switch 30 on the substrate 3 by the cover member 21 described above. The operation unit main body 20 is formed so that the operation front side (left side in FIG. 2) has a larger diameter than the operation back side (right side in FIG. 2). The operation unit body 20 has a hollow cylindrical shape at the center, and is formed in a double structure in which the inner peripheral surface portion 20a and the outer peripheral surface portion 20b face each other. A space is formed between the inner peripheral surface portion 20a and the outer peripheral surface portion 20b of the operation unit main body 20, and a connection line 42 described later is inserted through the space.

  A coil antenna 40 is attached to the inside of the operation member 2 on the operation front side. The coil antenna 40 is configured by winding a copper wire around a bobbin-like member, and performs power supply to the portable device and information reception. The coil antenna 40 is electrically connected to the substrate 3 and connected to a connection line 42 for supplying power and transmitting signals.

  The coil antenna 40 has an outer shape substantially matching the inner peripheral surface of the cover member 21, and is disposed on the operation front side of the operation member 2 by integrating the operation unit main body 20 and the cover member 21. The The connection line 42 is configured to be inserted into a space between the inner peripheral surface portion 20a and the outer peripheral surface portion 20b of the operation unit main body 20 and to pass through a predetermined path.

  As described above, the illumination member 50 that illuminates the push switch 30 and the operation member 2 is arranged on the substrate 3 on the inner side of the inner peripheral surface portion 20a. In addition, components for supplying power and transmitting signals to the coil antenna 40 are also arranged, but these are not shown. The push switch 30 is well known, has a rubber rubber portion, and has a movable contact and a fixed contact inside. Instead of this, a magnetic or optical switch may be used. Further, the moving direction may be changed by a gear mechanism or the like, and a rotary switch, a slide switch, or the like may be used.

  FIG. 2 shows a cross-sectional view of the switch device. The intermediate member 12 constituting the housing 1 has a flange 12a on the outer peripheral surface, and the base member 10 and the surface side member 11 face each other with the flange 12a interposed therebetween.

  The connection line 42 extending from the attachment portion 41 of the coil antenna 40 is inserted through the space between the inner peripheral surface portion 20a and the outer peripheral surface portion 20b of the operation unit main body 20. Further, the connection line 42 is routed so as to be spiral with respect to the circumferential direction of the operation unit main body 20. In addition, the meaning of the spiral here means extending in the circumferential direction while changing the height, and does not mean only being wound 360 degrees or more. FIG. 3 is a front view of the coil antenna 40 and the operation unit main body 20, in which the outer peripheral surface part 20 b of the operation unit main body 20 is omitted, and FIG. 4 is a bottom view of the operation member 2.

In this way, the connection line 42 passes through a predetermined route by the guide portion 20c.

  When the operation member 2 is pushed, the distance between the coil antenna 40 and the substrate 3 also changes, so that the flexible connection line 42 is also deformed, but has a spiral path defined by the guide portion 20c. Therefore, there is a tolerance for deformation, and an excessive force is not applied to each mounting portion on the coil antenna 40 side and the substrate 3 side. Therefore, disconnection of the connection line 42 can be prevented. It should be noted that simply providing a margin does not allow sufficient control of the attitude of the connecting wire 42 to deform, and a load is applied so that the unsoldered portion is greatly displaced near the attachment portion or the attachment portion. Sometimes. However, this problem can be solved by guiding in this way.

  Further, as described above, the board 3 is provided with the illumination member. When the operation member 2 is illuminated with the illumination member by appropriately setting the path of the connection line 42, the connection line 42 is used. Generation of shadows can be prevented.

However, in the second embodiment, the housing 1 is provided with a guide portion 11a so that the connection line 42 has a path passing through the outer peripheral side of the operation member 2.

  FIG. 5 shows a cross-sectional view of the switch device according to the present embodiment. In the second embodiment, the housing 1 is composed of two members, a base member 10 and a surface side member 11. The front side member 11 is formed with a holding portion 11b protruding toward the inner peripheral side, and the outer peripheral surface of the operation member 2 is held and guided on the inner peripheral surface of the holding portion 11b.

  As in the first embodiment, the operation unit main body 20 constituting the operation member 2 has a double structure with the inner peripheral surface portion 20a and the outer peripheral surface portion 20b, and a space between the inner peripheral surface portion 20a and the outer peripheral surface portion 20b. Is provided with a light emitting rod 22. The light emitting rod 22 receives light from the illumination member of the substrate 3 and emits light at the front end portion on the operation front side to illuminate the operation front surface of the operation member 2. In the present embodiment, the path of the connection line 42 is set so as not to interfere with the light emitting rod 22 and to cause no shadow on the light.

  A hole-shaped guide portion 11a is formed on the surface-side member 11 constituting the housing 1 on the surface facing the operation front surface of the holding portion 11b. The connection line 42 passes through a path that passes through the guide portion 11a. Also, an insertion hole 20d is formed in the surface of the operation unit body 20 that faces the operation front surface, and the connection line 42 is inserted therethrough.

  In this embodiment, the attachment part 41 of the coil antenna 40 and the attachment part 31 of the board | substrate 3 are arrange | positioned in the same position in the circumferential direction. Similar to the first embodiment, the connecting line 42 connecting them is formed to be longer than the shortest distance between the mounting portion 41 on the coil antenna 40 side and the mounting portion on the substrate 3 side, and the path thereof. Is routed from the outer peripheral surface of the operation member 2 to the outer peripheral side by the guide portion. That is, the predetermined path of the connection line 42 in the present embodiment is bent toward the outer peripheral side of the operation member 2 between the attachment portion 41 of the coil antenna 40 and the attachment portion 31 of the substrate 3. In this way, the connection line 42 passes through a predetermined route by the guide portion 20c.

  Also in this embodiment, when the operation member 2 is pushed, the distance between the coil antenna 40 and the substrate 3 also changes, so that the flexible connection line 42 is also deformed, but the bent shape determined by the guide portion 20c. Therefore, there is a tolerance for deformation, and an excessive force is not applied to each attachment portion on the coil antenna 40 side and the substrate 3 side. Therefore, disconnection of the connection line 42 can be prevented. In addition, by setting the path of the connection line 42 so as not to interfere with the illumination by the light emitting rod 22, the occurrence of shadows can be prevented.

  Although the embodiment of the present invention has been described above, the application of the present invention is not limited to this embodiment, and can be applied in various ways within the scope of its technical idea.
