Abstract

The present invention discloses an adaptive cruise control emblem and a method of manufacturing the same. According to an embodiment of the present invention, there is provided a vehicle comprising: a film on which a logo of a vehicle is printed and which is permeable to radio waves; And an emblem which is ultrasonically fused with the film and which is capable of electron transmission.

Description

TECHNICAL FIELD [0001] The present invention relates to an adaptive cruise control emblem, and more particularly to an adaptive cruise control emblem,

The present invention relates to an adaptive cruise control emblem and a method of manufacturing the same.

Adaptive Cruise Control (ACC) or Smart Cruise Control (SCC) is a system that detects a vehicle ahead by using a radar sensor and keeps a certain distance from the preceding vehicle if there is a preceding vehicle. Cruise Control is an advanced form of Cruise Control that has both a function and a set-speed cruising feature that runs at a specific speed if no preceding vehicle is present.

Adaptive cruise control is a typical driver assistance / support system that has the effect of automating the acceleration and deceleration of the vehicle by using the engine control unit and the electronic braking unit, thereby improving the driver's convenience and reducing the risk of collision.

Generally, a radar sensor for ACC is located in front of the vehicle such as a grill, and a radio-transmissive film is disposed in front of the radar sensor.

However, when a film capable of transmitting radio waves is disposed in front of the grill, there is a problem that it is difficult to arrange a symbol emblem representing the vehicle ahead.

In order to solve the problems of the prior art described above, the present invention proposes an emblem having an ACC function and a manufacturing method thereof.

According to an embodiment of the present invention, there is provided a vehicle comprising: a film on which a logo of a vehicle is printed and which is permeable to radio waves; And an emblem which is ultrasonically fused with the film and which is capable of electron transmission.

According to another aspect of the present invention, there is provided a method of manufacturing a light emitting device, comprising: printing a vehicle logo on a radio wave transmissive film; And insert injection molding the film printed with the vehicle logo; And ultrasonic welding the injection-molded film with a housing through which radio waves can be transmitted.

According to the present invention, since the emblem is provided to allow radio wave transmission, there is an advantage that a separate film is not attached to the front of the radar sensor of the vehicle.

1 is a view showing the structure of an ACC emblem according to a preferred embodiment of the present invention.
2 is a view showing a film insert injection process according to an embodiment of the present invention.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail.

It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. Like reference numerals are used for like elements in describing each drawing.

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

1 is a view showing the structure of an ACC emblem according to a preferred embodiment of the present invention.

As shown in FIG. 1, the ACC emblem according to the present embodiment may include a transparent protective layer 100, a film 102, and a housing 104.

Here, the transparent protective layer 100 may be polycarbonate (PC) resin or acrylic.

The film 102 according to the present embodiment includes a first resin layer 110, a metal deposition layer 112, and a second resin layer 114.

The first resin layer 110 may be made of transparent acrylic or transparent polycarbonate.

The metal deposition layer 112 is formed by dispersing and depositing metal particles such as aluminum particles or chrome particles, and is capable of transmitting radio waves through dispersion deposition.

The second resin layer 114 may be an ABS resin (acrylonitrile-butadiene-styrene resin) or a polycarbonate resin.

According to a preferred embodiment of the present invention, a logo 101 of a vehicle having a predetermined color and design is printed on the upper side of the first resin layer 110.

At the time of manufacturing the emblem, a transparent housing 104 capable of electron transmission is provided below the film 102.

According to one embodiment of the present invention, the film 104 undergoes an insert injection process and is coupled with the housing 104 through ultrasonic welding.

2 is a view showing a film insert injection process according to an embodiment of the present invention.

Referring to Figure 2, the film 102 on which the logo 101 is printed is molded (step 200).

Step 200 may be thermoforming or vacuum forming, and is a process of forming the height or shape of the film 102 to match the shape of the transparent protective layer 100.

When thermoforming is performed, preferably, the thermoforming temperature may be 80 to 90 캜 for the top plate, the temperature of the bottom plate may be 70 to 80 캜, and the molding process may be performed for a time period of 10 to 50 seconds have.

A trimming process is then performed (step 202).

Trimming is a process of removing unnecessary portions of the film 102 to the transparent protective layer 100 in accordance with the size.

After part of the film 102 is removed, an insert injection is performed (step 204) in which the molded film is fixed to the injection mold and attached to the transparent protective layer 100.

In this way, the transparent protective layer 100 can be attached to the top of the film 102 through insert injection molding.

After insert injection, the bottom surface of the film 102 is bonded to the housing 104 via ultrasonic welding (step 206).

According to an embodiment of the present invention, the transparent protective layer 100 may be coated on the film 102 through a super gloss coating method.

In the high-gloss coating method, a coating composition is mixed to obtain a high-gloss uniform coating film, and a coating agent composition is prepared by mixing the coating agent composition with the reaction initiator mixture, and then the coating agent composition is coated on the coated object Conductor), and passing the plastic film and the coating roller at the same time to perform a coating treatment for the coating film, followed by a coating treatment and a hot air curing treatment.

In Fig. 2, reference numeral 101 denotes a coating composition.

The coating composition is prepared by mixing 9 to 1 weight parts of polymethyl methacrylate (hereinafter referred to as PMMA) 1 to 9: methyl methacrylate (hereinafter referred to as MMA) so as to have a viscosity of 50 to 250 poise It can be mixed.

In addition to the above-mentioned coating composition, a paint not containing an organic solvent such as a UV paint or a urethane paint, or a paint obtained by a polymerization reaction may be used.

The reaction initiator is a compound capable of forming a radical of a peroxide structure. The reaction initiator is dilauric peroxide (hereinafter referred to as DPO) or benzoyl peroxide (hereinafter referred to as BPO) ). &Lt; / RTI >

To facilitate the dissolution of the reaction initiator, they are mixed in a weight ratio of methyl ethyl ketone (MEK) 1-4: xylen 1-4: DPO 1-4, and 40-80 Lt; 0 > C to prepare a reaction initiator mixture.

After the reaction initiator mixture composition was prepared, dimethyl- beta -propiothetin (hereinafter referred to as 'DMPT') 5- (5'-hydroxyethyl) propane was added to the coating composition in an amount of 6- 10 kg of the coating composition and 100-400 g of the reaction initiator mixture. 40 g of an accelerator is further added and stirred to prepare a catalyst.
