Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lever switch device for a vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lever switch apparatus for a vehicle, and more particularly, to a lever switch apparatus for a vehicle which includes an operation lever for operating a user and allows a user to operate the configuration apparatus of the vehicle using the operation lever.

Typically, the vehicle steering wheel assembly includes a steering wheel, a steering column, a Sterring Roll Connector assembly, a multifunction switch assembly, and the like. The steering wheel is for the driver to set the steering direction, and the rotation of the steering wheel by the driver is transmitted to the wheel through the steering column to set the steering angle of the vehicle.

BACKGROUND ART [0002] Currently, vehicles such as automobiles are required to function as various convenience means capable of providing a more stable and comfortable riding state beyond a function as a moving means. For this reason, the vehicle is provided with various convenience devices and various switches for operating and controlling the same. Accordingly, various kinds of convenience facilities and various switches for operating and controlling the various facilities are provided in the vehicle, and various switches tend to be concentrated in the steering unit in consideration of the operability of the driver.

For example, a steering wheel of a currently produced vehicle is provided with a window switch for opening and closing a window, a steering light switch for turning on / off the steering light, an audio switch for driving audio, and a wiper switch for driving the wiper .

In addition to these various switch devices, components such as SRC (Steering Roll Connector) / Slip Ring that supply power to the switch device are disposed at the lower end of the steering wheel. These SRCs and slip rings occupy a considerable volume of the structure and require compactness of other components such as a switch device mounted on the steering wheel to efficiently use the space of the limited steering portion.

Typically, the light switch device and the wiper switch device are formed in a lever type so as to be disposed on the left side or the right side of the driver. In the case of a switch device composed of such a lever type, by moving the lever up and down with respect to the center of rotation, an electric signal for a predetermined mode desired by the driver can be generated to drive various components of the vehicle. The lever switch device has been improved to increase the operability of the driver and to prevent the driver from losing his / her frontal attention during operation.

However, in the conventional vehicle lever switch device, there is a problem that it is difficult for the user to select which mode the current configuration device is set after the user selects the operation mode of the configuration device by moving the lever. For example, the wiper device is provided with an auto mode for allowing the driver to arbitrarily operate the wiper, and for sensing the amount of external rainwater to operate the wiper. In the conventional vehicle lever switch device, It is difficult to intuitively distinguish which mode the operation mode of the wiper device is currently operating. Therefore, when the driver operates the lever in order to check the current operation mode of the wiper device during operation, the driving concentration of the driver is often lowered.

[ 5, the cam surface 129 is inclined toward the origin point 128 on the lower side of the origin point 128 and the cam surface 130 is inclined toward the origin point 128 on the upper side of the origin point 128 .

The end of the sub slide pin 125 is located at the origin point 128 when the operation lever 120 is placed at the neutral position for the up-down tilting operation. The end of the sub slide pin 125 slides in contact with the cam surface 129 when the operation lever 120 is tilted upward in the upward direction by the user and is out of the neutral position. At this time, the hinge lever 131 coupled to the lever skeleton portion 122 of the operation lever 120 is interlocked with the lever skeleton portion 122, and the hinge lever 131 is moved up and down The tilting sensor 117 generates an operation signal. Then, the control unit 118 of the circuit unit 115 operates the wiper motor 10 in the washer liquid injection mode in accordance with the operation signal of the up-and-down tilting sensor 117. When the driver releases the operation lever 120, the sub slide pin 125 of the operation lever 120 slides along the cam face 129 and returns to the origin point 128. This is also the case when the operation lever 120 is tilted downwardly by a user's operation. In this case, a different operation mode for the wiper motor 10 can be selected.

Referring to FIGS. 1, 3 to 5, the lever cover 132 is disposed outside the housing 110 while surrounding the lever skeleton 122.

The slide pin 138 is slidably inserted into the insertion groove 137 so that one end of the slide pin 138 protrudes outside the insertion groove 137. The spring 139 applies an elastic force to the slide pin 138 in a direction in which it protrudes outwardly of the insertion groove 137. The slide pin 138 and the spring 139 together with the cam block 150 installed inside the housing 110 serve to self-return the operation lever 120 during the left and right tilting operation of the operation lever 120 . The self-return operation of the operation lever 120 will be described later.

1 to 5, the operation button 140 is installed at an end of the lever body 121 disposed outside the housing 110 so that the driver can select an operation mode of the wiper device. A push switch 141 for generating a signal by the movement of the operation button 140 is provided inside the lever body 121. When the driver presses the operation button 140, the push switch 141 generates an operation signal and transmits it to the circuit unit 115. [ The push switch 141 is for selecting the auto mode (AUTO) among the operation modes of the wiper motor 10. When the driver selects the auto mode (AUTO) by pressing the operation button 140, the circuit unit 115 controls the wiper motor 10 using the signal of the rain sensor 20.

When the driver turns the adjustment knob 142, the rotation switch 143 generates an operation signal and transmits it to the circuit unit 115. [ When the operation mode of the wiper motor 10 is the low speed operation mode LO, the high speed operation mode HI or the intermittent operation mode MIST, the driver operates the adjustment knob 142 to adjust the driving speed of the wiper motor 10 Can be finely adjusted.

3 and 6, the cam block 150 has an origin point 151 and two cam faces 152 and 156 connected to the origin point 151. 6, one cam face 152 is inclined toward the home position 151 on the upper side of the home position 151 and the other cam face 156 is located on the lower side of the home position 151 151). The end of the slide pin 138 is located at the origin point 128 when the operation lever 120 is placed in the neutral position for the left and right tilting operation.

When the operating lever 120 is tilted in one direction (clockwise with reference to FIG. 3), the end of the slide pin 138 slides in contact with one cam surface 152. At this time, the left and right tilting sensors 116 of the circuit unit 115 generate operation signals in accordance with the tilting angle of the operation lever 120. The control unit 118 of the circuit unit 115 operates the wiper motor 10 in the low speed operation mode LO or the high speed operation mode HI in accordance with the operation signal of the left and right tilting sensor 116. [ When the driver tilts the operation lever 120 to select the low-speed operation mode LO or the high-speed operation mode HI and then releases the operation lever 120, the slide pin 138 of the operation lever 120 moves to the cam surface 152, The operation lever 120 is self-returned to the neutral position. The end of the slide pin 138 slides in contact with the other cam face 156 when the operation lever 120 is tilted in the other direction (counterclockwise with reference to Fig. 3). At this time, the left and right tilting sensors 116 of the circuit unit 115 generate operation signals in accordance with the tilting angle of the operation lever 120. The control unit 118 of the circuit unit 115 activates the wiper motor 10 in the intermittent operation mode MIST or turns off the wiper motor 10 in accordance with the operation signal of the left and right tilting sensor 116. When the driver tilts and releases the operation lever 120, the slide pin 138 of the operation lever 120 is slid along the cam face 156, so that the operation lever 120 is self-returned to the neutral position.

The two cam surfaces 152 and 156 of the cam block 150 are each structured to provide a sense of operation to the operation lever 120 when the operation lever 120 is tilted right and left.
