Definitions
- the present invention relates to a drive device for driving a base provided with a detection unit for detecting information or a transmission unit for transmitting information.
- Patent Document 1 discloses a sensor drive mechanism that rotates a sensor arranged in a target space in a horizontal direction and a vertical direction to rotate the sensor into the target space along a rectangular locus. ing.
- the sensor drive mechanism of Patent Document 1 operates a friction clutch when the rotation of the sensor holder is restricted at a predetermined position in the right direction or a predetermined position in the left direction, thereby rotating the sensor holder by the rotational force of the drive shaft. Is switched from the left-right direction to the up-down direction. Therefore, the sensor drive mechanism of Patent Document 1 becomes a complicated mechanism using a large number of parts such as a friction clutch and a plurality of gears for transmitting the rotational force of the drive shaft.
- the present invention has been made in view of such circumstances, and it is possible to detect information obtained from a wide detection range or transmit information to a wide transmission range by a relatively simple mechanism. It is an object of the present invention to provide a drive device.
- the drive device of the present invention employs the following means.
- the drive device includes a base provided with a detection unit that detects information obtained from a predetermined detection range or a transmission unit that transmits information to a predetermined transmission range, and a drive shaft that the drive unit rotates.
- the holding portion is provided with a holding portion that is attached to and holds the base portion, and the holding portion forms an inclined surface that is inclined by a predetermined angle with respect to a plane orthogonal to the axis on which the drive shaft is arranged, and is formed on the inclined surface. Rotate the base along the axis while holding the base.
- the holding portion attached to the drive shaft rotates around the axis.
- the inclined surface formed by the holding portion is inclined by a predetermined angle with respect to a plane orthogonal to the axis on which the drive shaft is arranged, and the base portion is held along the inclined surface. Therefore, as compared with the case where the base portion is arranged along the plane orthogonal to the axis line, the detection range of the detection unit or the transmission range of the transmission unit can be expanded by the amount corresponding to the inclination angle. That is, it is possible to provide a drive device capable of detecting information obtained from a wide detection range or transmitting information to a wide transmission range by a relatively simple mechanism.
- the drive device includes a base portion to which the holding portion is attached, and the holding portion has a first frame body that is swingably attached to the base portion around the first swing axis.
- a second frame having a flat bottom to which the first frame is mounted and the base is mounted so as to be swingable around a second swing axis orthogonal to the first swing axis, and a base end side
- the configuration may include a rotating member that is attached to the drive shaft and has the inclined surface formed on the tip end side, and rotates around the axis with the inclined surface in contact with the bottom portion.
- the rotating member of the holding portion attached to the drive shaft rotates around the axis as the drive shaft rotates around the axis.
- the rotating member rotates about the axis in a state where the inclined surface on the tip side is in contact with the bottom of the second frame. Therefore, the base portion attached to the bottom portion of the second frame body rotates around the axis while maintaining a predetermined angle along the inclined surface formed by the rotating member. Further, when the base rotates around the axis, the first frame swings around the first swing axis, and the second frame swings around the second swing axis orthogonal to the first swing axis. To do.
- the tilt angle of the base is a combination of the swing angle around the first swing shaft and the swing angle around the second swing shaft, a swing mechanism based on these two swing shafts is used.
- the detection range of the detection unit or the transmission range of the transmission unit can be expanded as compared with the case where the detection unit is not used.
- the rotating member rotates around the axis, while the base does not rotate around the axis even if the rotating member rotates. This is because the rotational motion by the rotating member is converted into a swing motion around the first swing shaft and the second swing shaft. Therefore, when the signal line or the power supply line is connected to the detection unit or the transmission unit, the signal line or the power supply line does not rotate with the rotation of the rotating member. Therefore, even if the rotating member is rotated around the axis, the vertical direction of the base is not reversed, and the signal line or the power supply line is appropriately prevented from being twisted or broken.
- the holding portion includes a holding member that holds the base portion via the inclined surface, and a support member that is attached to the drive shaft and supports the back surface side of the inclined surface.
- the holding member may be formed integrally with the supporting member.
- a plurality of the detection units may be provided on the base portion.
- the relative positional relationship of each detection unit is fixed, so that the detection accuracy when associating the detection results of the plurality of detection units is improved.
- the detection unit includes a motion sensor that detects a moving object in the predetermined detection range, a temperature sensor that detects a temperature in the predetermined detection range, and an illuminance in the predetermined detection range.
- An illuminance sensor that detects an illuminance sensor, a receiving unit that receives information transmitted from the predetermined detection range, an image sensor that acquires an image within the predetermined detection range, and a sensor that detects a refrigerant leak within the predetermined detection range. It may be at least one of.
- the present invention it is possible to provide a drive device capable of detecting information obtained from a wide detection range or transmitting information to a wide transmission range by a relatively simple mechanism.
