Description

Multi-function switch unit of vehicle {MULTI-FUNCTION SWITCH UNIT OF VEHICLE}

The present invention relates to a multi-function switch unit of a vehicle, and more particularly, to a multi-function switch unit of a vehicle that can improve the theft feeling between each operation mode by adding tension ribs to the theft.

In general, the multi-function switch unit of the vehicle is a component that is bound to the steering column under the steering wheel, and may be divided into a turn signal switch unit for operating a turn signal, a wiper switch unit for wiper and washer fluid operation, and the like. .

The conventional turn signal switch unit 10 is as shown in FIG.

The conventional turn signal switch unit 10 has a lever 11 which is moved up and down by the hinge part 12 when the driver operates, and a slider 13 which is elastically supported by the spring 14 according to the operation of the lever 11. A guide member 15 for guiding the slider 13 to move up and down, and a housing 116 provided with a theft mountain 117 in contact with the slider 13 and divided into respective operation modes.

Lever 11 moves up and down by a predetermined angle to make full left turn (FULL LH TURN)-left lane change (LH LANE CHANGE)-OFF (OFF)-right lane change (RH LANE CHANGE)-full right turn (FULL RH TURN) Select the operation mode.

As illustrated in (a) and (b) of FIG. 2, the moderation mountain 117 is configured in a shape in which a peak and a valley are repeated.

As such, the graph of the feeling of operation when the driver moves the lever 11 in the up and down direction is shown as shown in FIG.

Meanwhile, the conventional wiper switch unit 50 is as shown in FIG. 3, except that the housing 156 and the lever 51 in which the theft mount 157 is formed have the same function as the turn signal switch. Therefore, only other configurations will be described below.

The lever 51 moves up and down by a predetermined angle to select an operation mode of mist (MIST)-off (OFF)-intermittent (INT)-low speed (LO)-high speed (HI).

To this end, the housing 156 is formed with a mountain and valleys 157 made of mountains and valleys so as to be divided into respective operation modes, and the shape of the island 157 is shown in FIGS. 4A and 4B. same.

In this way, a graph of the feeling of operation when the driver moves the lever 51 in the up and down direction is shown as shown in FIG.

However, in such a conventional multi-function switch unit, there is a problem in that the mode is weak when the switch from one operation mode to another operation mode is difficult to switch to the desired operation mode.

For example, in the case of the turn signal switch unit 10, when the operation is performed from the OFF to the left lane change (LH LANE CHANGE) or the right lane change (RH LANE CHANGE) operation mode, the operation is not switched to the desired operation mode. It is turned to switch to FULL LH TURN or FULL RH TURN operating mode.

On the other hand, in the case of the wiper switch unit 50, the operation is switched to the low speed (LO) or the high speed (HI) operating mode when operating in the OFF (interactive) INT mode.

In order to improve this, the inclination of the stealing mountains 117 and 157 may be increased, but if the inclination of the stealing mountains 117 and 157 is increased in this way, a smooth smoothness may be obtained when the levers 11 and 51 are operated. There was a limit to the disappearance (the problem of theft of theft and smooth operation).

Accordingly, an object of the present invention is to provide a multi-function switch unit of a vehicle that can be operated smoothly in the desired operating mode by the driver by improving the theft while maintaining a smooth operation feeling.

The above object is, according to the multi-function switch unit of the vehicle of the present invention, the slider is moved up and down by the operation of the lever; It is divided into a plurality of operating modes, and is achieved by a housing with a stealed mountain having tension ribs protruding from the surface to increase the contact area with the slider in each interface section of the operating mode.

Here, the tension rib is formed on both sides of the slider so that the slider is in contact with the three parts by the stealing peak and the tension rib.

In this case, the tension rib may have a shape in which the contact area with the slider increases when the slider progresses from one operation mode to another in one direction.

The theft mountain has a shape in which the mountain and the valley are repeated, and it is preferable that shaking noise is prevented when the slider moves from the mountain to the valley to enter each operation mode.

As described above, according to the present invention, since the inclination of the theft mountain is not increased, not only a smooth operation feeling can be obtained, but also the tension ribs are formed on the theft mountain to increase the contact area with the slider, so as to increase the contact area with each slider. As the theft is improved, the multi-function switch unit of the vehicle is provided which can move the lever to the desired operation mode.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Prior to the description, components having the same configuration as in the prior art will be described in the related art by using the same reference numerals, and only different configurations will be described.

The multi-function switch unit of the vehicle is a component that is bound to a steering column under the steering wheel, and may be divided into a turn signal switch unit for operating a turn signal, a wiper switch unit for wiper and washer fluid operation, and the like.

Prior to the description, the turn signal switch unit and the wiper switch unit according to the present invention except for the housing in which the theft is formed, the rest of the configuration is the same as the conventional description thereof will be omitted.

As shown in FIGS. 5A and 5B, the housing 16 of the turn signal switch unit 10 is divided into a plurality of operation modes and contacts the slider 13 at each boundary section of the operation mode. In order to increase the area, a theft mount 17 having a tension rib 18 protruding from the surface is provided.

That is, the surface of the conventional theft 117, 157 is made of a flat surface, the sense of theft is weak, while the surface of the denomination 17 according to the present invention is three-dimensionally constituted by the tension ribs 18, the slider 13 There is an advantage that the theft can be improved because the contact resistance is large because it is in contact with the tension rib 18 as well as the theft 17.

The tension ribs 18 protrude from both sides of the slider 13 as shown in FIGS. 6A to 6C, whereby the sliders 13 are connected to the tension ribs 18 on both sides. Three parts are brought into point contact by the stealing mountain 17.

Here, when the slider 13 is in the FULL LH TURN operating mode, the slider 13 contacts L-shaped mountains 17 and the tension ribs 18 on both sides by L0 as shown in FIG. When the slider 13 is in the OFF operation mode, the slider 13 is in contact with the stealing peak 17 and the tension ribs 18 on both sides by L1 as shown in FIG. . At this time, the shape of the tension ribs 18 is formed such that the contact area L1 in the OFF operation mode is larger than the contact area L0 in the FULL LH TURN operation mode.

On the other hand, when the slider 13 is located in the RH LANE CHANGE operation mode, the slider 13 is as large as theft 17 and both tension ribs 18 and L2 as shown in FIG. In this case, the shape of the tension ribs 18 is preferably formed such that L2 is larger than L1.

With this arrangement, the graph of the feeling of operation when the driver moves the lever 11 in the up and down direction is as shown in Fig. 5 (c), where the tension ribs 18 are different in one direction from the slider 13 in one operation mode. Since the contact area with the slider 13 becomes large when advancing to the operation mode, it is possible to obtain the effect of increasing the operational feeling from (a) 'to (b)'.

That is, comparing the graph (b) 'of the driver's operation feeling according to the present invention with the conventional graph (a)', the left lane change (LH LANE CHANGE) or the right lane change (RH LANE CHANGE) operation in the OFF (OFF) Theft of the mode and the boundary of the FULL LH TURN operation mode at the LH LANE CHANGE and the mode of the FULL RH TURN operation mode boundary at the RH LANE CHANGE It can be seen that it is clearly distinguished.

Meanwhile, as shown in FIGS. 7A and 7B, the housing 56 of the wiper switch unit 50 is divided into a plurality of operation modes and contacts the slider 13 at each boundary section of the operation mode. In order to increase the area, a stealing mountain 57 is formed with a tension rib 58 protruding from the surface.

At this time, the tension ribs 58 protrude from both sides of the slider 13 as shown in FIGS. 8A to 8C, whereby the sliders 13 have tension ribs on both sides. 58) and the stealing mountain 57, the three parts are in point contact.

Here, when the slider 13 is located in the mist (MIST) operating mode, the slider 13 is in contact with the moderation peak 57 and the tension ribs 58 on both sides by L0 'as shown in FIG. When the slider 13 is located at the mountain when the switch is switched from the OFF to the intermittent (INT) operation mode, the slider 13 is formed by theft mount 57 and the tension ribs at both sides as shown in FIG. 58) and L1 '. At this time, the shape of the tension ribs 58 is formed so that the contact area L1 'becomes larger than the contact area L0'.

On the other hand, when the slider 13 is located on the mountain when switching from the intermittent (INT) to the low speed (LO) operating mode, the slider 13 is theft mountain 57 and the tension ribs on both sides as shown in FIG. 58) is in contact with L2 ', and the slider 13 is located at the mountain when switching from the low speed (LO) to the high speed (HI) operating mode. 57) and the tension ribs 58 on both sides by L3 '. At this time, the shape of the tension ribs 58 is preferably formed such that L2 'is larger than L1' and L3 'is larger than L2'.

Accordingly, according to the present invention, when the slider 13 proceeds from one operation mode to another operation mode in one direction, unlike in the conventional art (see P-line of FIG. 4C) in which the operating force was constant according to the speed of the wiper. The shape of the tension ribs 18 and 58 is increased so that the contact area with the slider 13 increases, and thus the operating force may be proportionally changed according to the speed of the wiper (see Q line in FIG. 7C).

In addition, when the slider 13 moved from the mountain of the stealing mountains 17 and 57 to the valley, vibration noise of the levers 11 and 51 was generated by the tension of the spring 14, according to the present invention. Since the slider 13 is guided in the state where the tension ribs 18 and 58 are in contact with both sides of the slider 13 when moving from the peak to the goal, vibration noise of the levers 11 and 51 can be prevented.

As described above, according to the present invention, since the inclination of the stealing mountains 17 and 57 is not increased, not only a smooth feeling of operation can be obtained, but also the tension ribs 18 and 58 are formed in the stealing mountains 17 and 57. By increasing the contact area with the slider 13, the theft is improved in each boundary section of the operation mode, so that the driver can move the levers 11 and 51 in the desired operation mode.
