Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention provides switches such as an air conditioner operation switch, an audio operation switch, and a hazard switch, which are provided in an instrument in front of a driver's seat of an automobile, to a driver's request. The present invention relates to a switch for an automobile, which can be replaced and used at an arbitrary location which is easy to use.

[Related Art] With the recent increase in the number of on-vehicle equipment such as safe driving equipment, audio equipment, and air conditioners, the number of operation switches for operating the on-vehicle equipment is increasing in recent automobiles. It is increasing at present.

However, in the vicinity of the driver's seat, the space for installing each of the operation switches is limited, and in the current vehicle, for example, a narrow portion such as a periphery of a lid cluster, a horn pad portion of a steering wheel, a steering spoke portion, or the like. The operation switch is provided using a space.

[Problems to be Solved by the Invention] However, a steering wheel is provided in front of the driver's seat, and is obstructed by the steering wheel for a driver in a position different in position, and a lid cluster ahead of the steering wheel. There are cases where the operability of the above operation switches provided in places such as is poor or does not suit the characteristics and preferences of the driver, but in such cases, the frequency of use of the switches and the characteristics of individual drivers -The position of the operation switch body could not be interchanged and changed according to preference, and there was a problem in terms of safe driving or switch operation.

Means for Solving the Problems In view of the points related to the present invention, among the operation switches arranged near the driver's seat, for example, an operation switch with a high use frequency and an operation switch with a low use frequency are included. Operation switches with high frequency can be replaced with low-frequency operation switches at the position where the user (driver) can use them most easily, to improve operability and improve safe driving. It is a measure of improvement.

That is, in the conventional operation switches, the mounting positions of the operation switches are determined, and when a large number of the operation switches are arranged, it is impossible to freely change the arrangement order. Although it was possible, in the present invention, the configuration is such that the frequently used operation switch can be arbitrarily replaced with another operation switch located at a position where the driver can easily operate, according to a request for a driving difference. Accordingly, it is an object of the present invention to provide a switchable switch for an automobile configured to improve the operability of a frequently-used operation switch.

[Examples] The present invention will be described in detail below based on examples shown in the drawings.

Reference numeral 1 denotes an instrument provided in front of a driver's seat of an automobile, and the instrument 1 includes a speedometer,
A meter 2 such as a tachometer is incorporated. A substantially semicircular lid cluster 3 for preventing reflection of external light from the side surface to the upper surface of the meter 2 group is formed integrally with the instrument 1, but along the periphery of the semicircular lid cluster 3. Replaceable switch 4 which is the gist of the present invention
Is provided. Referring to FIG. 2, the mounting structure of the replaceable switch will be described. The guide cluster 5 of the switch is mounted on the lid cluster 3 by an appropriate fixing means.
A plurality of connector portions 22 to which the switch body 6 can be replaced and fitted are formed at regular intervals. The connector portion 22 is provided with a ridge 7 for guiding the switch body 6. Formed on the upper surface of each ridge 7 are a projection window 10 of a contact plate 9 connected to a light guide window 8 and a communication circuit, and a holding portion 12 of a positioning sphere 11 of the switch body 6.
The locking holes 12 of the switch body 6 are provided on both sides of the ridge 7.
Are drilled.

On the back surface of the switch body 6, a concave groove 13 to be fitted to the ridge 7 and a hook portion 14 to be engaged in each of the locking holes 12 are formed. A contact 15 which is in contact with the contact plate 9 and a recess into which the sphere 11 falls
16 are provided. Further, an operation knob 17 of the switch is held on the surface of the switch body 6 so as to be able to be pushed. When the operation knob 17 is pressed, the switch 18 shown in FIG. It is closed. 19 is built into each switch body 6,
Have an address that can operate a specific device
Indicates IC.

As described above, the guide blade 5 having a large number of ridges 7 for fitting the switch body 6 is attached to the lid cluster 3, and each of the ridges 7 of the guide plate 5 is attached to each switch body 6 having a single structure. Is configured to be detachably and replaceably held. That is, the hooks 14 of the switch body are inserted into the locking holes 12 from above the locking holes 12 formed on both sides of the projection 7 provided on the guide plate 5, and then the switch body 6 is The sphere 11 is recessed by sliding
16, the switch body 6 is positioned, and the hooks 14 are locked on the lower surface of the locking holes 12, so that the switch plate 6 can be selectively mounted on the guide plate 5 at the appropriate ridge 7 position. As a result, the switch body is connected to the contact plate 9 provided on the guide plate 5.

The communication circuit 20 to which the contact plate 9 provided on each ridge 7 is connected is wired inside the guide plate 5, and the circuit also serves as a power source as shown in FIG. It consists of a communication line a and a ground line b.
A contact plate 9 for connecting the switch body 6 is connected in parallel. The communication circuit 20 includes a control circuit 21
Are connected to respective devices such as an audio system, an air conditioner, a hazard lamp, and an anti-fog device via the.

As described above, in this embodiment, the communication circuit 20 for controlling devices such as audio equipment, air conditioners, and hazard lamps installed in the vehicle is routed in the vehicle interior, and furthermore, the communication circuit 20 is specified in any part of the communication circuit. It has a communication IC that has an address for controlling the on-vehicle device, and has a structure in which a single-shaped switch body can be detachably connected in parallel. Switch body, for example, can be replaced and changed to a favorite position that is easy for the driver to operate, thereby improving the control operability of the in-vehicle device, and thus improving the control operability of the device during driving and driving, This is useful for safe driving.

[Effects of the Invention] As described above, according to the present invention, a plurality of connector portions connected to a communication circuit for controlling equipment installed in a vehicle and a plurality of connector portions fitted to the respective connector portions are provided. The switch body has a communication IC having an address for controlling only a specific device among the devices, and can be arbitrarily replaced and fitted to the plurality of connector portions. Since the switch is a replacement type switch for an automobile, a switch body that is frequently used by the driver or a switch body that the driver wants to attach importance to can be changed according to the characteristics (eg, right-handed or left-handed) or preference of the driver. Can be replaced arbitrarily in the connector section of the above. Therefore, a specific switch body for controlling a specific device can be replaced and used at a position desired by the driver, thereby improving the control operability of the device during driving, for example, and contributing to safe driving. In addition, the switch body 6 that can be freely replaced with each connector part is equipped with a communication IC of an address corresponding to various in-vehicle devices,
When the switch body is replaced, it is not necessary to change the existing harness, and it is not necessary to prepare a specific harness in advance.
