Structure for mounting stoke switches

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to structure for mounting steering wheel column lever type switches (hereinafter referred to as stoke switches) for vehicles such as automobiles, and more particularly to structure for mounting stoke switches capable of being mounted so as to enable them to be left-right exchanged.

2. Description of the Prior Art

Conventional structure for mounting stoke switches will be described. Although the illustration is omitted, on the lateral sides of a steering column, there are mounted stoke switches having different functions, which have operating levers for controlling operations of wipers, headlights, turn signals and the like.

The stoke switches are mounted to the steering column by screwing or the like, and the operating levers are adapted to be rockable.

In a vehicle such as an automobile having a steering column to which such stoke switches are mounted, the position of the steering wheel generally differs depending upon whether for Japanese domestic use or for export to Europe, America and the like. In the case of vehicles for Japanese domestic use, a right-steering wheel vehicle is used, and the steering wheel is mounted on the right side toward the traveling direction, while in the case of vehicles for Europe, America and the like, a left-steering wheel vehicle is used, and the steering wheel is mounted on the left side toward the traveling direction.

As regards a stoke switch to be mounted to a steering column having a function for, for example, a wiper operation, it is mounted on the left side of the steering column in the case of the right-steering wheel vehicle, while it is mounted on the right side of the steering column in the case of the left-steering wheel vehicle.

Even in a stoke switch having functions of headlights and turn signal switches, if there is a switch having another function to be added to these functions, the design has been newly performed from the beginning.

In the conventional structure for mounting stoke switches, however, even if an attempt is made to left-right exchange a stoke switch mounted on the left side of the steering column in, for example, a right-steering wheel vehicle for mounting it to the right side of the steering column in a left-steering wheel vehicle, it could not be performed because the left and right stoke switches have not been designed so as to be exchangeable. Accordingly, even if they are stoke switches having the same function, exclusively used stoke switches have had to be prepared respectively between the right-steering wheel vehicle for domestic use and the left-steering wheel vehicle for export to Europe, America and the like, and therefore, control has been a demanding task due to the increasing variety of stoke switches.

Also, even if a stoke switch is made left-right exchangeable and the stoke switch is left-right exchanged, there has been a problem that a function mark formed on the stoke switch, for indicating the function is turned upside down, and cannot be recognized.

Also, when a stoke switch having another function added is placed on an one-sided receiving portion for exchanging instead of left-right exchange, the design has had to be newly performed from the beginning and it has taken a lot of time and labor.

In addition, since the stoke switch has been mounted to the steering column by screwing or the like, the assembly was a demanding task.

SUMMARY OF THE INVENTION

Also, as means for solving the problem, the structure is arranged such that the indicating member is capable of being mounted to the mounting unit of the operating lever by snap engagement in accordance with the function of the stoke switch.

Since the first and second stoke switches

which can be extracted and inserted have been designed so as to be left-right exchangeable with respect to the steering column

1

, for example, the first and second stoke switches

4

and

8

mounted to a right-steering wheel vehicle for domestic use can be mounted to a left- steering wheel vehicle for export to Europe and America by left-right exchanging.

When the first and second stoke switches

As shown in

A connector unit

. In this manner, the first and second stoke switches

4

and

8

are constructed respectively.

A connector unit

14

arranged on the left side of the steering column

is formed such that it is partitioned into a first conduction unit

consisting of sockets D, E and F, and a second conduction unit

14

14

a

, and a first conduction unit

14

b

consisting of sockets D, E and F in a position opposed to the second conduction unit

respectively.

In other words, the connector units

14

and

15

on the lateral sides of the steering column

1

are constructed to have the first and second conduction units

14

a

,

14

b

,

15

a

and

15

b

which are capable of being connected to the first and second connecting units

5

d

and

9

d

of the stoke switches

4

and

8

respectively.

When the first stoke switch

is inserted into the left-side connector unit

14

shown in

FIG. 6

, the first connecting unit

5

is adapted to be connected to the first conduction unit

FIG. 7

, and the first stoke switch

4

is inserted into the right-side connector unit

15

as shown and the second stoke switch

is adapted to be connected to the second conduction unit

15

In other words, when the first and second stoke switches

4

and

8

are exchanged respectively and are inserted into the lateral sides of the steering column

1

, the first connecting unit

5

d

of the first stoke switch

4

is connected to the first conduction unit

14

a

of the steering column

1

, and the second connecting unit

9

d

of the second stoke switch

8

is connected to the second conduction unit

15

b

in such a manner that discrimination between the first and second stoke switches

4

and

8

can be performed by the respective connector units

14

and

15

of the steering column

1

.

In the present invention, the description has been made of the example in which the connector units

5

a

and

9

a

of the first and second stoke switches

4

and

8

consist of a plurality of pin terminals and the connector units

14

and

15

on the steering column

1

side consist of a plurality of sockets, but it is possible to construct such that the connector units

5

a

and

9

a

of the first and second stoke switches

4

and

8

consist of a plurality of sockets and the connector units

14

and

15

on the steering column

1

side consist of a plurality of pin terminals.

According to the present invention, the first and second (plural) stoke switches

4

and

8

to be inserted into the lateral sides of the steering column

1

can be discriminated by the connector units

14

and

15

on the steering column

1

side as described above. Therefore, when first and second stoke switches

4

and

8

mounted to a right-steering wheel vehicle for domestic use are extracted respectively and are left-right exchanged to be mounted to a left-steering wheel vehicle for export to Europe and America, the first and second stoke switches

4

and

8

can be discriminated to thereby enable their respective functions to be performed.

For this reason, the first and second stoke switches

4

and

8

having different functions respectively do not need any left or right exclusive stoke switch, and the variety of the stoke switches can be reduced.

When, however, such first and second stoke switches

4

and

8

as described above are extracted and inserted to be left-right exchanged, for example, a function mark

7

a

, formed on an indicating member

7

of the first stoke switch

4

for indicating a wiper operation, is turned upside down, and it becomes difficult to recognize the function mark

7

a.

As a measure against it, according to the present invention, an indicating member

7

formed like a flat plate having a rectangular external shape is detachably mounted to a rectangular hole-shaped mounting unit

6

a formed in the first stoke switch

4

as shown in FIG.

2

.

Thus, on the lateral sides of the indicating member

7

, there are projectingly formed a pair of snap legs

7

b

in such a manner that the indicating member

7

can be mounted to the mounting unit

6

a by snap engagement.

When the stoke switch

4

is extracted from and inserted into the steering column

1

for left-right exchanging, the indicating member

7

with the function mark

7

a

turned upside down is adapted to be extracted to correct the direction thereof.

As another method of recognizing the function mark

7

a

when the first and second stoke switches

4

and

8

are left-right exchanged, there may be used the structure in which as shown in

FIG. 3

, a first stoke switch

24

is mounted to a proximal portion

25

in such a manner that the center line

26

a

of an operating lever

26

mounted to extend from the proximal portion

25

in the extending direction becomes substantially horizontal, the operating lever

26

a

is formed with a function mark

26

a

for indicating the type of the first stoke switch

24

, and the function mark

26

a

is formed to incline the direction thereof in the center line

26

a

direction of the operating lever

26

. In

FIG. 3

, reference numeral

26

c

denotes an operation switch.

Also, as another method, there may be used the structure in which for a first stoke switch

34

shown in

FIG. 4

, there are prepared two types for each of operating levers having the same function: a left-hand operating lever

36

and a right-hand operating lever

40

, and when the stoke switch

34

is exchanged from right to left, the right-hand operating lever

40

is replaced with the left-hand operating lever

36

correspondingly to the direction of mounting the stoke switch

34

.

As regards such operating levers

6

and

10

for the first and second steering wheel column lever type switches

4

and

8

as described above, a description has been made of those linearly extending from the proximal portions

5

and

9

, but a first steering wheel column lever type switch

44

may be one with its operating lever

46

bent in an irregular shape as shown in FIG.

5

. The operating lever

46

is formed with a mounting unit

46

a

, which is detachably mounted with an indicating member

47

having a function mark

47

a

. In

FIG. 5

, reference numeral

46

a

denotes an operation switch.

Therefore, as regards a request for changing a mounting angle of the stoke switch with respect to the steering column

1

, the mounting angle of the stoke switch

45

with respect to the steering column

1

can be arbitrarily changed without changing the exclusively-used stoke switch or the mounting member

3

within the steering column

1

depending upon the type of an automobile.

In the first embodiment according to the present invention, the description has been made of the stoke switch only on the first stoke switch side, but since the second stoke switch side has also the same structure, a description thereof is omitted.

A description will be made of a second embodiment in which the first and second stoke switches

4

and

8

are discriminated when such first and second stoke switches

4

and

8

mounted on the lateral sides of the steering column

1

to enable them to be extracted and inserted as shown in

FIG. 1

are left-right exchanged. Within the first and second stoke switches

4

and

8

, discrimination codes (not shown) consisting of fixed resistors having different resistances respectively are mounted.

On the steering column

1

side, there is provided discrimination means capable of discriminating the discrimination codes, and this discrimination means is provided with an arithmetic processing unit (not shown) such as CPU and a reference resistor (not shown) consisting of a predetermined resistance.

As another method, there may be also used the structure in which when the stoke switches

4

and

8

are extracted from and inserted into the steering column

1

for left-right exchanging, the arithmetic processing unit on the steering column

1

side detects ratios of the resistance value of the reference resistor to the resistances of the fixed resistors in the first and second stoke switches

4

and

8

to discriminate the first and second stoke switches

4

and

8

respectively, and their functions are caused to be performed respectively.

Also, the discrimination means consisting of the fixed resistor is capable of discriminating not only two stoke switches (first and second)

4

and

8

, but also a plurality of stoke switches having any other functions, by mounting a fixed resistor having a different resistance from these two stoke switches

4

and

8

. In addition, in the above-described embodiments, the description has been made of the case where the left and right stoke switches are exchanged, but the present invention is not limited thereto, but in the case of, for example, a left-side stoke switch of a Japanese vehicle, although its function is usually a wiper operation (F/R wiper), the left-side stoke switch can be caused to have a different function (such as F wiper) by changing the fixed resistor and indicating member which provide the discrimination codes in the same shape.

Effect of the Invention

The structure for mounting stoke switches according to the present invention is such that a plurality of stoke switches having different functions mounted to the steering column on both sides to enable them to be extracted and inserted have different discrimination codes respectively, and the steering column has discrimination means capable of discriminating the discrimination codes in such a manner that this discrimination means discriminates between the discrimination codes of the stoke switches to be mounted to the steering column. Therefore, even if a plurality of stoke switches having different functions are exchanged respectively to be mounted to the steering column, there can be provided the structure for mounting stoke switches capable of easily discriminating between stoke switches having different functions by means of the discrimination codes and the discrimination means.

Also, the plurality of stoke switches have the discrimination codes consisting of fixed resistors having different resistances respectively, the discrimination means includes an arithmetic processing unit provided on the steering column side and a reference resistor consisting of a predetermined resistance, and when the stoke switches are extracted from and inserted into the steering column for exchanging, the arithmetic processing unit detects a ratio of the resistance of the reference resistor to the resistance of the fixed resistor of each of the stoke switches to cause the functions of the stoke switches to be performed respectively. Therefore, it is possible to easily discriminate between the plurality of stoke switches having different functions by means of low-cost components such as fixed resistors.

Also, each of the stoke switches has a mounting unit for detachably mounting, in the operating lever, an indicating member, on which a function mark for indicating the function of the stoke switch has been formed, and when the stoke switches are extracted from and inserted into the steering column for exchanging, it has been made possible to correct the direction of the function mark by attaching and detaching the indicating member. Therefore, even if stoke switches having the same function are left-right exchanged respectively between a right-steering wheel vehicle and a left-steering wheel vehicle, the function marks can be recognized only by correcting the direction of the function mark by extracting and inserting the indicating members, and the variety of the stoke switch can be reduced.

Also, the indicating member has been arranged to be mounted to the mounting unit of the operating lever by snap engagement, and therefore, the indicating member can be easily attached and detached with a single motion, and the assembly efficiency is excellent.

Also, the stoke switch is such that the operating lever is mounted to the proximal portion in such a manner that the center line of the operating lever in the extending direction from the proximal portion becomes substantially horizontal, the operating lever has a function mark for indicating the function of the stoke switch, and the function mark is formed so as to incline the direction thereof in the center line direction of the operating lever. Therefore, even if stoke switches having the same function are left-right exchanged respectively, it is possible to recognize the function marks, and the variety of the stoke switch can be reduced.

The stoke switch is such that the operating lever is detachably mounted to the proximal portion, the operating lever has a function mark for indicating the function of the stoke switch, there are provided two types (right-hand and left-hand) for each of the operating levers having the same function, and when the stoke switches are left-right exchanged and are mounted to the lateral sides of the steering column, any appropriate ones of the operating levers are arranged to be exchanged correspondingly to the respective mounting directions of the stoke switches. Therefore, it is possible to provide structure for mounting stoke switches, having excellent assembly property, capable of recognizing the function mark only by exchanging the right-hand and left-hand operating levers when the stoke switches are left-right exchanged.

Also, since the stoke switch has the operating lever formed by bending it in an irregular shape, the mounting angle of the stoke switch with respect to the steering column can be arbitrarily changed depending upon the type of a vehicle.

Also, since the steering column has a mounting member capable of snap-engaging with the proximal portion of the stoke switch within and the proximal portion of the stoke switch is arranged to be mounted to the mounting member by snap engagement, assembly time when the stoke switch is mounted to the steering column can be shortened.

Also, the first and second stoke switches, mounted on the lateral sides of the steering column to enable them to be extracted and inserted, having a switching circuit within respectively are provided with a connector unit respectively, each of these connector units is made connectable to connector units provided on the lateral sides of the steering column respectively, the connector unit of the first stoke switch has a first connecting unit, and the connector unit of the second stoke switch has a second connecting unit in such a manner that when the first and second stoke switches are extracted from and inserted into the steering column, the first and second connecting units are connected to the connector units on the steering column side respectively and discrimination between the first and second stoke switches is arranged to be performed. Therefore, it is possible to left-right exchange the first and second stoke switches between a right-steering wheel vehicle and a left-steering wheel vehicle for mounting, and to reduce the variety of the stoke switch. For this reason, it becomes easier to control the stoke switches, and the expenses for inventory control and the like can be reduced.

Also, the connector units on the lateral sides of the steering column have first and second conduction units, to which the first and second connecting units are capable of being connected respectively, in such a manner that when the first and second stoke switches are inserted into the lateral sides of the steering column respectively, the first connecting unit of the first stoke switch is connected to the first conduction unit in the steering column, and the second connecting unit of the second stoke switch is connected to the second conduction unit respectively, and that discrimination between the first and second stoke switches can be performed. Therefore, it is possible to discriminate between the stoke switches left-right exchanged with low-cost components such as connectors, and to manufacture the structure for mounting stoke switches at low cost.
