Abstract

A touch control device includes a base including a metal complex; a sensing pattern formed in a pattern groove formed in a touch area of the base and including a conductive material; and a wire arranged in a wire groove outside of the touch area of the base and connecting the sensing pattern and an integrated circuit, the wire including a conductive material.

First claim

What is claimed is:

1. A touch control device comprising:
a base including a metal complex and integrally provided with a first area into which a touch signal is input and a second area in which an integrated circuit is mounted;
a first pattern groove formed on a first side of the base by irradiating laser to the first side of the base;
a second pattern groove formed on a second side of the base by irradiating laser to the second side of the base;
a first sensing pattern disposed in the first pattern groove in the first area and including a first conductive material by a plating or deposition process in the first pattern groove;
a second sensing pattern disposed in the second pattern groove on the second side of the base and including a second conductive material by a plating or deposition process in the second pattern groove;
a first wire groove formed on the first side of the base by irradiating laser to the first side of the base;
a second wire groove formed on the second side of the base by irradiating laser to the second side of the base;
a first wire disposed in the first wire groove in the second area and connecting the first sensing pattern to the integrated circuit, the first wire including a third conductive material by a plating or deposition process in the first wire groove; and
a second wire disposed in the second wire groove on the second side of the base and connecting the second sensing pattern to the integrated circuit, the second wire including a fourth conductive material by a plating or deposition process in the second pattern groove,
wherein the first area has a concave curved surface.

2. The touch control device of claim 1 ,
wherein the first pattern groove and the first wire groove are connected to each other, and
the second pattern groove and the second wire groove are connected to each other.

3. The touch control device of claim 1 ,
wherein the first sensing pattern and the first wire are formed integrally, and
the second sensing pattern and the second wire are formed integrally.

4. The touch control device of claim 1 ,
wherein the base comprises resin selected from one or more of Polycarbonate (PC), Polyamide (PA), and acrylonitrile-butadiene-styrene copolymer (ABS), and metal oxide selected from one or more of Mg, Cr, Cu, Ba, Fe, Ti, and Al.

5. The touch control device of claim 1 ,
wherein the base is formed by being coated on resin, glass, or leather.

6. The touch control device of claim 1 ,
wherein the base comprises a first base and a second base laminated in a touch area of the first base.

7. A vehicle including the touch control device of claim 1 .

8. The vehicle of claim 7 ,
wherein the touch control device is installed in a centralized control system installed in a gearbox.

9. A method for manufacturing a touch control device, the method comprising steps of:
preparing a base including a metal complex and integrally provided with a first area into which a touch signal is input and a second area in which an integrated circuit is mounted, the first area having a concave curved surface;
forming a first pattern groove by irradiating laser on the first area on a first side of the base;
forming a second pattern groove by irradiating laser on a second side of the base;
forming a first wire groove by irradiating laser on the second area on the first side of the base;
forming a second wire groove by irradiating laser on the second side of the base;
forming a first sensing pattern including a first conductive material by a plating or deposition process in the first pattern groove;
forming a second sensing pattern including a second conductive material by a plating or deposition process in the second pattern groove;
forming a first wire including a third conductive material by a plating or deposition process in the first wire groove; forming a second wire including a fourth conductive material by a plating or deposition process in the second wire groove; and
mounting the integrated circuit in the second area to electrically connect to the first wire and the second wire.

10. The method of claim 9 ,
wherein irradiating laser on the first side of the base comprises having metal seeds exposed in the first pattern groove, the second pattern groove, the first wire groove, and the second wire groove, and
wherein the plating or deposition process of the first sensing pattern, the second sensing pattern, the first wire, and the second wire comprises having the first, second, third and fourth conductive materials, respectively, stuck to the metal seeds.

11. The method of claim 9 ,
wherein the first pattern groove, the second pattern groove, the first wire groove, and the second wire groove are formed in the same process.

12. The method of claim 9 ,
further comprising a step of applying current to the first and second sensing patterns, examining a change in mutual capacitance between the two sensing patterns, and determining whether the patterns fit for sensors based on the examination result.

13. The method of claim 9 ,
further comprising a step of coating the base on resin, glass, or leather.

14. A touch control device comprising:
a single base including a metal complex and integrally provided with a first area into which a touch signal is input and a second area in which an integrated circuit is mounted;
a first pattern groove formed on a first side of the base in the first area;
a second pattern groove formed on a second side, opposing the first side, of the base in the first area;
a first sensing pattern disposed in the first pattern groove on the first side of the base and including a first conductive material;
a second sensing pattern disposed in the second pattern groove on the second side of the base and including a second conductive material;
a first wire groove formed on the first side of the base in the second area;
a second wire groove formed on the second side of the base in the second area;
a first wire disposed in the first wire groove on the first side of the base and connecting the first sensing pattern to the integrated circuit, the first wire including a third conductive material; and
a second wire disposed in the second wire groove on the second side of the base and connecting the second sensing pattern to the integrated circuit, the second wire including a fourth conductive material,
wherein the first area has a concave curved surface.
