The effects of the present disclosure are not limited to the above-described effects. It should be understood that the effects of the present disclosure include all inferable effects in the following description.
It is understood that the term “vehicle” or “vehicular” or other similar term as used herein is inclusive of motor vehicles in general such as passenger automobiles including sports utility vehicles (SUV), buses, trucks, various commercial vehicles, watercraft including a variety of boats and ships, aircraft, and the like, and includes hybrid vehicles, electric vehicles, plug-in hybrid electric vehicles, hydrogen-powered vehicles and other alternative fuel vehicles (e.g. fuels derived from resources other than petroleum). As referred to herein, a hybrid vehicle is a vehicle that has two or more sources of power, for example both gasoline-powered and electric-powered vehicles.
The above and other features of the disclosure are discussed infra.
The above and other features of the present disclosure will now be described in detail with reference to certain exemplary embodiments thereof illustrated the accompanying drawings which are given herein below by way of illustration only, and thus are not limitative of the present disclosure, and wherein:
It should be understood that the appended drawings are not necessarily to scale, presenting a somewhat simplified representation of various preferred features illustrative of the basic principles of the disclosure. The specific design features of the present disclosure as disclosed herein, including, for example, specific dimensions, orientations, locations, and shapes will be determined in section by the particular intended application and use environment.
In the figures, reference numbers refer to the same or equivalent sections of the present disclosure throughout the several figures of the drawing.
The above and other objects, features, and advantages of the present disclosure will be readily understood from the following preferred embodiments with reference to the accompanying drawings. However, the present disclosure is not limited to the embodiments described herein but may also be specified in other forms. Rather, the embodiments disclosed herein are provided so that the disclosed contents may be thorough and complete, and the spirit of the disclosure may be fully conveyed to those skilled in the art.
Like reference numerals have been used for like elements while describing each drawing. In the accompanying drawings, the dimensions of the structures are shown enlarged from the actual for the sake of clarity of the present disclosure. The terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another component. For example, without departing from the scope of the present disclosure, a first component may be referred to as a second component, and similarly, the second component may also be referred to as the first component. The singular expressions include plural expressions unless the context clearly dictates otherwise.
In this specification, it should be understood that the terms “comprises” or “having”, etc. refer to the presence of features, integers, steps, operations, components, parts, or combinations thereof described in the specification, but do not preclude the presence or addition possibility of one or more other features, integers, steps, operations, components, parts, or combinations thereof. Further, when a portion such as a layer, a film, an area, or a plate is referred to as being “on” another portion, this includes not only the case where it is “directly on” another portion, but also the case where there is another portion in between. On the contrary, when a portion such as a layer, a film, an area, or a plate is referred to as being “under” another portion, this includes not only the case where it is “directly underneath” another part but also there is another portion in between.
Unless otherwise specified, it should be understood that since all numbers, values, and/or representations that express components, reaction conditions, polymer compositions, and the amount of combinations used in the specification are approximations reflecting the various uncertainties of the measurement that occurs to obtain such values among essentially different ones by such numbers, they are expressed by the term “about” in all cases. Further, when a numerical range is disclosed in this specification, such a range is contiguous and includes all values from the minimum value of this range to the maximum value including the maximum value, unless otherwise indicated. Further, when such a range refers to an integer, all integers including from the minimum value to the maximum value including the maximum value are included unless otherwise indicated.
In general, an IMS module may be positioned inside the door and assembled with a door garnish. An IMS may be optionally provided or is not provided. Thus, the specification of the door garnish may depend on whether the IMS is provided or not, which may increase costs as separate investment costs may additionally incurred for making molds for making different garnishes. In order to construct an IMS system, costs for manufacturing different materials such as a button, a housing mold, and a surface treatment.
Further, mechanical buttons are not suitable for the latest technology trends such as an electric vehicle.
Referring to
The touch button (A′) is provided such that light emitted from a light source of an IMS module is displayed to be shown from outside, and only the surface of the door garnish is normally displayed and the touch button (A′) may be displayed at the moment of touching a proximity sensor or touch sensor or a portion of the sensor to be operated. However, the display format is not limited thereto and the touch button (A′) may also be displayed in the IMS display area (A) at all times.
Referring to
The body part 10 may include a translucent transparent substrate 11 and a shielding coating layer 12 provided behind the transparent substrate 11, and the coating layer 12 having holes 12a that may form a certain shape, e.g., symbol.
The transparent substrate 11 may be made of a material and a thickness capable of transmitting light emitted from a light source 21a provided in the IMS module 20. Although not limited thereto, the transparent substrate 11 may be selected from a group consisting of polycarbonate, polymethylmethacrylate, glycol-modified polyethylene terephthalate, and a combination thereof.
The transparent substrate 11 may include an inorganic pigment for reflecting and/or diffusing the light emitted from the light source of the IMS module.
The shielding coating layer 12 may be formed in a black color so as to shield light in order to prevent light from spreading to portions other than the touch button (A′) and the frame (A″).
The shielding coating layer 12 includes the holes 12a, which may be formed by cutting portions of the layer material 12 corresponding to the shapes of the touch button (A′) and the frame (A″). The holes 12a may be formed by a suitable method, and for example, formed by using a laser cutting apparatus. A portion of the light emitted from the light source described later may be emitted to the outside through the holes 12a. Other light is absorbed and/or blocked by the shielding coating layer 12 so that a certain shape of the display area (A) as in
The shielding coating layer 12 may include 4 wt % to 10 wt % of carbon black in order to block the light. If the content of the carbon black is too small, the shielding rate may be lowered, and if it is too much, the appearance and the mechanical properties may be lowered.
The body part 10 may further include a white painting layer 13 provided between the transparent substrate 11 and the shielding coating layer 12.
The white painting layer 13 is configured to reflect the light emitted from the light source. For this purpose, the white painting layer 13 may include an inorganic pigment.
The inorganic pigment is not specially limited, and any material capable of reflecting light may be used. For example, titanium dioxide (TiO2), etc. may be used.
The white painting layer 13 may contain 20 wt % to 30 wt % of the inorganic pigment. If the content of the inorganic pigment is too low, the degree of light diffusion may be insufficient, and if it is too much, the light transmittance may be lowered.
The body part 10 may further include a high glossy painting layer 14 provided in front of the transparent substrate 11 and a primer layer 15 provided between the transparent substrate 11 and the high glossy painting layer 14.
The high glossy painting layer 14 is a configuration for implementing a high-quality feeling by giving gloss to the door garnish 1.
The high glossy painting layer 14 may include a glossy paint. The paint contains a base resin, a curing agent, a pigment, a coloring agent, and a solvent, and may further contain additives according to the purpose. The content and type of each component are not specially limited and may be appropriately adjusted according to the purpose. However, it is preferable that the pigment is added with 3 wt % to 5 wt % for light transmission of the high glossy painting layer 14.
The light transmittance of the high glossy painting layer 14 may be 8% to 24%. If the light transmittance is too low, the light emitted from the light source may not be output to the extent identifiable by a driver, and if the light transmittance is too high, the internal structure may be projected, thereby lowering the feeling of high quality.
The body part 10 may further include a clear painting layer 16, which is a kind of protection layer, on the outermost portion thereof.
Referring to
Although any of the light source 21a may be used as long as it may emit light, it is preferable to use an LED.
The light source 21a may be provided at the position corresponding to the touch button (A′) of the IMS display area (A).
The housing 22 may include a front case 22a for providing a space capable of receiving the PCB 21 and a rear case 22b for shielding the open rear of the front case 22a.
The front case 22a may include a through hole 22c formed at the position corresponding to the light source 21a. Accordingly, the light emitted from the light source 21a may pass through the housing 22.
The IMS module 20 may include a touch film 23 provided in front of the housing 22 and for transferring a touch signal to the PCB 21.
The touch part 23a may be a shape that does not cover the through hole 22c formed to penetrate the front case 22a.
The signal transfer part 23b may be electrically connected with a control part 21b of the PCB 21. When the signal transfer part 23b transfers the touch signal generated from the touch part 23a to the control part 21b, the control part 21b operates the light source 21a so that the IMS display area (A) is displayed outside the door garnish 1.
At this time, when an Electroluminescent (EL) film is mounted to the rim of the touch film 23 to operate together with the light source 21a, the rim (A″) may be displayed together with the touch button (A′) as in
