## Abstract

A haptic generator for panels of vehicles and an interior panel for vehicles using the same are proposed. The haptic generator includes a first coupling member with a first end integrally coupled to at a rear surface of a panel, a casing coupled to a second end of the first coupling member, a haptic actuator stored in the casing and configured to generate haptic vibration, a second coupling member with a first end integrally coupled to the rear surface of the panel, a support member coupled to a second end of the second coupling member, a touch sensor coupled to the rear surface of the panel with a predetermined distance from the support member, a PCB panel supported by the support member, and a display provided on a portion of a surface of the panel and configured to supply information about a switch.

## Claims

### Claim 1

A haptic generator provided inside a vehicle, the haptic generator comprising:
a panel comprising a front surface facing a forward direction and a rear surface facing a rearward direction opposite to the forward direction
a first coupling member whose first end is integrally coupled to the rear surface of the panel;
a casing coupled to a second end of the first coupling member;
a haptic actuator stored in the casing and configured to produce a vibration used for a haptic feedback;
a second coupling member whose first end is integrally coupled to the rear surface of the panel;
a support member comprising a forward support member portion extending substantially parallel to the panel and positioned at a rear of the panel, a side support member portion extending toward the rearward direction from the forward support member portion, and a coupling support member portion protruding from the side support member portion toward the second coupling member;
a touch sensor coupled to the rear surface of the panel while being spaced apart from the forward support member portion at a predetermined distance;
a printed circuit board (PCB) panel; and
a display provided on the front surface of the panel, and configured to provide information about a switch, wherein, when viewed from a front of the display, the display covers a portion the touch sensor is disposed on the rear surface of the panel,
wherein the forward support member portion has a first hole through which the first coupling member passes, the side support member portion is configured to support the PCB panel, and the coupling support member portion is configured to be coupled to a second end of the second coupling member.

### Claim 2 (depends on 1)

The haptic generator of claim 1, further comprising:
a back cover coupled to the side support member portion to form a space storing the casing, the support member, the touch sensor, and the PCB panel.

### Claim 3 (depends on 2)

a light emitting diode (LED) mounted to the PCB panel.

### Claim 4 (depends on 3)

The haptic generator of claim 3, further comprising:
an illuminance sensor provided in the vehicle, wherein an activation and a deactivation of the LED is determined in response to an in-vehicle illuminance measured by the illuminance sensor.

### Claim 5 (depends on 3)

The haptic generator of claim 3, wherein the display is activated by turning on the LED when a touch signal from a user is detected by the touch sensor.

### Claim 6 (depends on 1)

### Claim 9 (depends on 1)

An interior panel for a vehicle, the interior panel comprising:
the haptic generator described in claim 1.

### Claim 10 (depends on 9)

The interior panel of claim 9, further comprising:
a back cover coupled to the side support member portion to form a space storing the casing, the support member, the touch sensor, and the PCB panel.

### Claim 11 (depends on 10)

The interior panel of claim 10, further comprising:
a light emitting diode (LED) mounted to the PCB panel.

### Claim 12 (depends on 11)

an illuminance sensor provided in the vehicle, wherein an activation and a deactivation of the LED is determined in response to an in-vehicle illuminance measured by the illuminance sensor.

### Claim 13 (depends on 11)

The interior panel of claim 11, wherein the display is activated by turning on the LED when a touch signal from a user is detected by the touch sensor.

### Claim 14 (depends on 9)

The interior panel of claim 9, further comprising:
a light emitting diode (LED) mounted to the PCB panel.

### Claim 15 (depends on 14)

The interior panel of claim 14, further comprising:
