Hereinafter, an embodiment of a wiper having an antenna according to the present invention will be described with reference to the accompanying drawings. In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

1 is a perspective view of a vehicle equipped with a wiper having an antenna according to an embodiment of the present invention.

Referring to FIG. 1, a wiper 100 having an antenna according to an embodiment of the present invention includes a wiper arm 110 and an antenna unit 200.

The wiper arm 110 is connected to the vehicle body 10 and rotatably rotated by external operation. The wiper arm 110 connects the blade portion 130 to the end portion. The blade portion 130 is reciprocally rotated together with the wiper arm 110 and serves to wipe the glass 20. The wiper 100 including the wiper arm 110 and the blade 130 is connected to the vehicle body 10 so as to be exposed to the outside of the vehicle body 10. At this time, the position of the glass 20 with respect to the vehicle body 10 is not limited. Particularly, the wiper arm 110 is rotatably mounted on the vehicle body 10 by the lock portion 120. [ Here, the arm fixing portion 120 is shown as a fin that rotatably connects the wiper arm 110 to the vehicle body 10. [ Of course, the encryption / decryption unit 120 is applicable in various ways.

Since the wiper 100 is assembled to the vehicle body 10 while being exposed to the outside of the vehicle body 10, the antenna unit 200 is directly formed or provided in the wiper 100, so that a separate external antenna is unnecessary . In addition, since the antenna unit 200 is formed or provided in the wiper 100 exposed to the outside of the vehicle body 10, the radio wave reception rate of the antenna unit 200 is not lower than the radio wave reception rate of the external antenna. Here, the antenna unit 200 receives radio waves of electrical components (not shown) such as GPS, DMB, radio, and black box installed in the vehicle body 10. [

In particular, the antenna portion 200 includes the conductive pattern layer 220. The conductive pattern layer 220 is formed by printing with a conductive ink. The conductive ink is printed by a piezoelectric inkjet method or the like, whereby the conductive pattern layer 220 is formed. The conductive ink is an ink liquid having conductor properties.

At this time, the conductive pattern layer 220 may be formed by applying conductive ink directly to the wiper arm 110, but it is preferable that the conductive pattern layer 220 is separately provided in the wiper arm 110 for convenience of replacement and maintenance.

FIG. 2 is a bottom perspective view of a wiper arm equipped with an antenna unit of a wiper according to an embodiment of the present invention, and FIG. 3 is a sectional view showing a state in which an insulation board of an antenna unit is mounted on a wiper arm according to an embodiment of the present invention.

FIG. 4 is a perspective view of a patterned insulating board according to an embodiment of the present invention, FIG. 5 is an exploded perspective view illustrating a state where a cable is connected to a patterning portion of an insulating board according to an embodiment of the present invention, Sectional view showing a wiring state of an insulation board according to an embodiment of the present invention.

2 to 6, the antenna unit 200 includes an insulation board 210, a signal transmission cable member 230, and a connector 240.

The insulating board 210 is made of an insulating material such as resin and is provided inside the wiper arm 110. The wiper arm 110 is mounted on the inner side of the insulating board 210 to form a recessed groove which is opened in the direction of the glass 20 so as to be protected from the outside. The insulating board 210 forms the conductive pattern layer 220. That is, the conductive pattern layer 220 is formed by printing conductive ink on the insulating board 210 provided inside the wiper arm 110. As the conductive pattern layer 220 is positioned outside the vehicle body 10 by the wiper arm 110, the radio wave reception rate can be maintained by the conventional external antenna. At this time, since the external antenna is unnecessary, the manufacturing cost and the maintenance cost of the vehicle are reduced.

In addition, the conductive pattern layer 220 receives a radio wave and transmits a signal to each electric component through a wire. Thus, the conductive pattern layer 220 of the insulation board 210 is electrically connected to each electric component through the signal transmission cable member 230. That is, the signal transmission cable member 230 is connected to one side of the conductive pattern layer 220 to apply a frequency to the electrical component. At this time, the insulation board 210 on which the conductive pattern layer 220 is formed can not be installed up to each electric component in the vehicle body 10, and the manufacturing cost is increased, so that the insulation board 210, which is provided inside the wiper arm 110, The electric wave from the conductive pattern layer 220 of the antenna 210 is transmitted to each electrical component via the signal transmission cable member 230. In particular, as the signal transmission cable member 230 is connected to each electrical component, the layout of the wiring becomes free.

In addition, the signal transmission cable member 230 must be firmly fixed to the insulating board 210 on which the conductive pattern layer 220 is formed. Thus, the connector 240 is provided. The connector 240 serves to connect the conductive pattern layer 220 and the signal transmission cable member 230 in a detachable manner.

The signal transmission cable member 230 may be cut or damaged while bumping against the vehicle body when the wiper arm 110 rotates. 1, the arm fixing unit 120 includes a bracket 122, and the bracket 122 forms a guide hole 124 for inserting and aligning the signal transmission cable member 230. As shown in FIG. The guide hole 124 is formed in an arc shape along the rotation locus of the wiper arm 110. Thus, when the wiper arm 110 is rotated, the signal transmission cable member 230 is protected by being guided along the guide hole 124 formed along the arc path.

In particular, the connector 240 includes a female housing 242 and a mail housing 244.

The female housing 242 has therein a first terminal 243 that contacts the conductive pattern layer 220. That is, the insulating board 210 penetrates the via hole 224 to correspond to one side of the conductive pattern layer 220. The first terminal 243 is inserted into the via hole 224 and fixed by bonding, soldering or the like. Accordingly, the first terminal 243 is electrically connected to the conductive pattern layer 220. Of course, the first terminal 243 is fixed inside the female housing 242.

In addition, the mail housing 244 is releasably bound to the female housing 242. [ At this time, the mail housing 244 is bound to the mail housing 242 by various methods. In addition, the mail housing 244 is provided with a second terminal 249. When the mail housing 244 and the female housing 242 are engaged, the second terminal 249 comes into contact with the first terminal 243. The second terminal 249 connects the signal transmission cable member 230. The first terminal 243 and the second terminal 249 are connected when the mail housing 244 and the female housing 242 are coupled to each other, (230). ≪ / RTI >

In addition, the female housing 242 is preferably fixed to the insulating board 210.

In one embodiment, the female housing 242 forms a recess 245 on the rear side for inserting the insulating board 210. Thus, one side edge of the insulating board 210 is inserted into the concave groove 245. At this time, the female housing 242 must be detached from the insulating board 210 optionally. Therefore, fitting projections 247 are protruded from the inner side surfaces of the concave grooves 245, respectively. Then, the insulating board 210 forms the fitting groove 212 to receive the fitting projection 247. [ That is, when the insulating board 210 is inserted into the concave groove 245 of the female housing 242, the fitting protrusions 247 protruding from the inner surface of the concave groove 245 protrude from the insertion hole 245 of the female housing 242, The female housing 242 is firmly fixed to the insulating board 210 as it is fitted into the groove 212.

Meanwhile, the wiper arm 110 is preferably made of a steel material so as to firmly support the blade portion 130 for wiping the glass 20. Thus, the wiper arm 110 can receive radio waves. The insulating board 210 is detachably coupled to the wiper arm 110. The insulating board 210 is releasably bound to the wiper arm 110 by the conductor binding member 222 contacting the conductive pattern layer 220. [ That is, the conductor bundling member 222 is inserted into the insulating board 210 while being in contact with the conductive pattern layer 220, and then is fastened to the inside of the wiper arm 110. At this time, the conductor connecting member 222 is preferably made of a steel material. As a result, as the wiper arm 110 receives the radio wave together with the conductive pattern layer 220, the radio wave receiving rate is improved.

7 is an enlarged cross-sectional view of an insulation board according to an embodiment of the present invention.

Referring to FIG. 7, the insulating board 210 forms a coating layer 310 by coating a coating liquid before the conductive pattern layer 220 is formed. That is, the coating layer 310 is coated with the coating liquid on the upper surface of the insulating board 210. Then, conductive ink is coated on the upper surface of the coating layer 310 to form the conductive pattern layer 220. The reason for forming the coating layer 310 is that blurring occurs when the conductive ink is directly applied to the insulating board 210.

In addition, an insulating layer 320 is formed on the upper surface of the conductive pattern layer 220. The insulating layer 320 is formed by printing an insulating ink on the upper surface of the conductive pattern layer 220. The insulating ink is coated on the entire upper side of the insulating board 210 including the conductive pattern layer 220 or only on the upper side of the conductive pattern layer 220 and then dried by UV beam irradiation or the like. At this time, the insulating layer 320 plays a role of having high wettability and adhesion at the time of bonding with the conductive pattern layer 220, and protects the conductive pattern layer 220. Particularly, the insulating ink forming the insulating layer 320 is preferably an ink liquid having high dimensional stability because the shape of the insulating ink is hardly deformed at the time of curing.

A waterproof layer 330 is formed on the insulating layer 320. The waterproof layer 330 forms the uppermost layer of the insulation board 210 and is coated with a film or coated with a transparent silicone resin and then dried to protect foreign substances such as water from entering the conductive pattern layer 220 do.
