Abstract

A sensor-cluster apparatus, in which a sensor configured to detect and collect external environment information is mounted in a case. The sensor-cluster apparatus includes a body member on which one kind or more of sensors are mounted on one surface thereof, a case in which an inner space is provided, and one surface thereof is opened to define an opening and on which the body member is mounted so that each of the sensors is exposed to the opening, and a position control device mounted inside the case to adjust a mounting position or a mounting angle of the body member.

First claim

What is claimed is:

1. A sensor-cluster apparatus including a plurality of sensors configured to detect and collect external environment information is mounted in a case, the sensor-cluster apparatus comprising:
a body member on which a plurality of different kinds of sensors are mounted on one surface thereof;
a case having an inner space, and one surface thereof is opened to define an opening and on which the body member is mounted so that each of the sensors is exposed to the opening; and
a position control device mounted inside the case to and configured to adjust a mounting position or a mounting angle of the body member,
wherein the position control device comprises:
a ball joint in which a ball stud having a ball at an end thereof and a casing stud having a casing, which accommodates the ball and allows the ball stud to be freely rotated, at an end thereof are coupled to each other;
a tension spring having one end connected to the case and the other end connected to the body member to provide elastic force that resists a tensile load; and
an actuator configured to press the body member within the case.

2. The sensor-cluster apparatus of claim 1 , wherein
one of the ball stud and the casing stud is fixed to the body member, and the other is fixed to the case;
a mounting position and a mounting angle of the body member are maintained by the tension spring; and
when the actuator presses the body member, the actuator overcomes the elastic force of the tension spring, and the mounting position and the mounting angle of the body member are changed.

3. The sensor-cluster apparatus of claim 2 , wherein the ball joint, the tension spring, and the actuator are mounted on a surface of the body member, which is opposite to the surface on which the sensors are mounted.

4. The sensor-cluster apparatus of claim 3 , wherein the actuator comprises:
a cylinder having a hollow cylindrical shape; and
a piston slidably mounted inside the cylinder and disposed so that an end of the piston presses the body member.

5. The sensor-cluster apparatus of claim 3 , wherein:
the ball joint, the tension spring, and the actuator form one adjustment set; and
at least two or more adjustment sets are installed at positions that are spaced apart from each other, respectively.

6. The sensor-cluster apparatus of claim 5 , wherein:
the body member has a rectangular plate shape having four vertices; and
the adjustment set is disposed in the vicinity of two vertices which are diagonally connected to each other in the body member, respectively.

7. The sensor-cluster apparatus of claim 6 , wherein the ball joint and the tension spring are additionally installed in the body member and the case in addition to the ball joint and the tension spring, which are provided in the adjustment set, respectively.

8. The sensor-cluster apparatus of claim 7 , wherein the ball joint and the tension spring that are additionally installed in addition to the ball joint and the tension spring, which are provided in the adjustment set, are installed in the vicinity of one of remaining two vertices except for the two vertices at which the adjustment set is disposed in the body member.

9. The sensor-cluster apparatus of claim 2 , wherein the plurality of kinds of sensors comprise:
a camera sensor disposed within the case to face the opening, the camera sensor being configured to recognize an object in a visible light wavelength region;
an infrared sensor disposed within the case to face the opening, the infrared sensor being configured to recognize an object in an infrared light wavelength region;
a lidar sensor disposed within the case to face the opening, the lidar sensor being configured to emit an optical pulse and detect an object through a reflected carrier signal, thereby mapping a distance; and
a radar sensor disposed within the case to face the opening, the radar sensor being configured to emit electromagnetic waves and detect an object through a reflected carrier signal, thereby mapping a distance.

10. The sensor-cluster apparatus of claim 9 , wherein:
one radar sensor, one camera sensor, two infrared sensors, and two lidar sensors are mounted on the body member;
the radar sensor and the camera sensor are disposed at a center of the body member, the camera sensor being disposed above the radar sensor; and
the lidar sensors and the infrared sensors are respectively disposed at both sides of the body member with the camera sensor and the radar sensor therebetween, the infrared sensors being disposed above the lidar sensors.

11. The sensor-cluster apparatus of claim 10 , wherein each of the infrared sensor, the camera sensor, the lidar sensor, and the radar sensor is detachably coupled to the body member.

12. The sensor-cluster apparatus of claim 1 , further comprising a cover coupled to the case to cover the opening,
wherein the cover is made of a material through which infrared rays, visible light, optical pulses, and electromagnetic waves are transmittable.

13. The sensor-cluster apparatus of claim 12 , wherein:
the cover opens and closes the opening by a sliding device; and
the sliding device comprises:
a motor configured to axially rotate a rotation shaft;
a gear assembly configured to convert rotation movement of the rotation shaft into sliding movement; and

a slidable part coupled to the cover so as to be slid by the gear assembly.
