Abstract

A radar apparatus for a vehicle includes a radar unit provided at an inner side of a radiator grill for a vehicle, a multi-layer transmission cover which is fitted into the radar unit and on a front surface of which a plurality of transmission layers through which a radar beam radiated through the radar unit transmits are formed, and a mounting portion in which a connection body formed by connecting the multi-layer transmission cover to the radar unit is connected to a vehicle body.

First claim

What is claimed is:

1. A radar apparatus for a vehicle comprising:
a radar unit provided adjacent an inner side of a radiator grill for a vehicle;
a multi-layer transmission cover fitted on the radar unit and including a front surface having a plurality of transmission layers through which a radar beam radiated from the radar unit transmits; and
a mounting portion including a connection body connecting the multi-layer transmission cover to the radar unit, the mounting portion also being connected to a vehicle body,
wherein the mounting portion comprises:
a supporting portion provided with a supporting bar that is extended downward vertically from a lower side of the connection body and a sliding bar that is extended in a left and right direction of a vehicle at a lower side of the supporting bar; and
a guide portion which is extended vertically from a vehicle body, and an upper end of which is bent to a front surface and the bent portion is divided into plural segments to form a grip portions at both sides where the supporting bar is fixed therebetween and a sliding portion at a center to which the sliding bar is fixed.

2. The radar apparatus for the vehicle of claim 1 , wherein the transmission layer of the multi-layer transmission cover is composed of a transparent resin layer formed at the outermost of the multi-layer transmission cover, a base that makes a thickness of the transparent resin layer uniform, and a metallic layer having a metallic effect similar to a metallic appearance of a radiator grill.

3. The radar apparatus for the vehicle of claim 1 , wherein the transmission layer of the multi-layer transmission cover is slanted at an angle such that the layer gradually becomes wider in downward direction from an upward portion to form a plane that is parallel to a radiator grill.

4. The radar apparatus for the vehicle according to claim 1 , wherein the multi-layer transmission cover is shaped to cover a front surface of the radar unit.

5. The radar apparatus for the vehicle according to claim 1 , wherein sections of the supporting bars and the sliding bars have inversed “T” shapes.

6. The radar apparatus for the vehicle according to claim 1 , wherein an upwardly indented catching groove is formed at the lower side of the sliding bar and a catching protrusion is formed at the upper side of the sliding portion wherein the catching protrusion is fitted into the catching groove.

7. The radar apparatus for the vehicle according to claim 6 , wherein the catching protrusion has a slope that is gradually raised from a front to a rear of a vehicle so that, during a head-on collision, the catching groove rides over the catching protrusion to be slid thereover for the sliding bar of the connection body to be separated toward a rear of a vehicle.

8. The radar apparatus for the vehicle according to claim 1 , wherein a catching protrusion is formed at the lower side of the sliding bar and a catching groove is formed at the upper side of the sliding portion wherein the catching protrusion is fitted into the catching groove.

9. The radar apparatus for the vehicle according to claim 8 , wherein the catching protrusion has a slope that is gradually raised from a front to a rear of a vehicle so that, during a head-on collision, the catching groove rides over the catching protrusion to be slid thereover for the sliding bar of the connection body to be separated toward a rear of a vehicle.

10. The radar apparatus for the vehicle according to claim 1 , wherein in the guide portion, a grip hole is formed between inner both sides of the grip portion and a side hole is formed at a side of the sliding portion wherein a sectional area of the side hole is larger than that of the grip hole.

11. The radar apparatus for the vehicle according to claim 1 , wherein in the guide portion a height of the sliding portion is lower than that of the grip portion.

12. The radar apparatus for the vehicle according to claim 1 , wherein the front ends of the grip portion and the slinging portion of the guide portion are bent to form an easy slope upwardly or downwardly.

13. The radar apparatus for the vehicle according to claim 1 , wherein the supporting portion is formed at a lower side of the multi-layer transmission cover.

14. The radar apparatus for the vehicle according to claim 1 , wherein the supporting portion is formed at a lower side of the radar unit.

15. The radar apparatus for the vehicle according to claim 1 , wherein the supporting portion includes a plurality of supporting portions.
