Description

A switch apparatus for an automobile The present disclosure relates to a switch device for an automobile, and more specifically, to a dial-type switch device. Various switching devices are installed in the interior of a vehicle. These switching devices are used to control the vehicle's various functions. Automotive switch devices are classified into push-type switch devices, dial-type switch devices, seesaw-type switch devices, touch-type switch devices, etc., depending on how the user operates them. In the above dial-type device, when a user rotates the knob, the knob rotates in a circumferential direction, and an angle sensor mounted inside the case detects this to generate a switch signal. The above-described touch-type switch device is equipped with a touchpad that detects a user's finger touch, and generates a switch signal as the user's finger touches the touchpad. Conventionally, the functions of a vehicle have been controlled by installing the aforementioned various types of switch devices inside the vehicle. However, due to the limited interior space of the vehicle, there was a problem of insufficient space to accommodate all the switches required to control the vehicle's functions. In addition, since the feel of the switch varies depending on the type, there was a problem requiring the separate installation of switches suitable for each situation. This could lead to a shortage of interior space and reduced space utilization efficiency. These issues cause inconvenience when using the vehicle, and the need for various parts in the production process can increase the cost of purchasing the car. FIG. 1 is a switch device of an automobile according to one embodiment of the present disclosure. FIG. 2 is a cutaway perspective view of a switch device of an automobile according to one embodiment of the present disclosure. FIG. 3 is an exploded perspective view of a dial module according to one embodiment of the present disclosure. FIG. 4 is a cross-sectional view of a dial module according to one embodiment of the present disclosure. FIG. 5 is a drawing showing the operating principle of a switch device of an automobile according to one embodiment of the present disclosure, and is a drawing in a state where the knob cover is not rotated. FIG. 6 is a drawing showing the operating principle of a switch device of an automobile according to one embodiment of the present disclosure, and is a drawing of a state in which a knob cover begins to rotate. FIG. 7 is a diagram showing the operating principle of a switch device of an automobile according to one embodiment of the present disclosure, and is a diagram showing the state in which a virtual cursor of a knob cover passes the midpoint between the stops. FIG. 8 is a diagram showing the operating principle of a switch device of an automobile according to one embodiment of the present disclosure, and is a diagram of the state before the virtual cursor of the knob cover reaches the next stop.
