Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is to perform various tests by irradiating light in all directions while moving through a light irradiation main bank composed of a large number of heat-dissipating bulbs and their reflecting mirrors for a passenger car or the like installed in a test chamber. The present invention relates to a movable light irradiation device to be used.
[0002]
[Prior art]
As conventional movable solar radiation devices, the following two devices have been proposed. First, as a first device, Japanese Patent Application Laid-Open No. 4-54431 discloses a horizontal moving rail provided with a vertical moving rail supported above a gantry and a semicircular horizontal moving rail installed on a floor surface. There is disclosed a structure in which a base having a vertical movement rail is configured to be horizontally movable, and a light irradiation bank is vertically moved along the vertical movement rail. As a second device, Japanese Patent Laid-Open No. 7-280706 discloses a light irradiation bank in a vertical direction on a linear bank rail that rotates on a large circular rail with the center point of the circular rail as a rotation center. The solar radiation apparatus of the structure suspended so that rotation was possible was disclosed.
[0003]
[Problems to be solved by the invention]
In the first conventional apparatus, in order to irradiate light from the front, rear, left, right, diagonal directions and upward of the passenger car, it is necessary to extend the arch rail from the upper part of the passenger car to the floor surface. In addition, by extending the arch rail from the top of the passenger car to the floor surface, the turning radius of the arch rail has to be large because the distance from the turning center to the floor surface of the arch rail must be large, and it is a large room for installation. Need.
[0004]
Furthermore, since the light irradiation device has a huge amount of light bulb wiring, whether the turntable is semicircular or partially cut away in order to secure wiring space as in the first conventional device described above. Or, it is necessary to secure a wiring space outside the turntable as in the second conventional device, and for that purpose, even if it cannot be rotated 360 degrees, the device must be enlarged and installed. Need a big room.
[0005]
Therefore, the object of the present invention is to easily move the light irradiation main bank to an arbitrary position above, behind, right and left of the irradiated object such as a passenger car and above in a narrow test room, and without moving the irradiated object. An object of the present invention is to provide a movable light irradiation apparatus that can irradiate light from a position and can be installed in a space-saving manner.
[0006]
[Means for Solving the Problems]
The first feature of the present invention that achieves the above object is that a turntable provided on an upper part on which an irradiated object is installed, an arch rail suspended from the turntable, and a bank that can move along the archrail A light irradiation main bank composed of a frame, a number of light bulbs suspended from the bank frame and their reflecting mirrors, and an auxiliary bank provided alongside the light irradiation main bank, the bank frame being eccentric downward By suspending the arch rail, the light irradiating main bank can be easily moved to an arbitrary position in the front, rear, left, right, and upper side of the passenger car without extending the arch rail to the floor.
[0007]
According to the present invention, since the arch rail does not extend to the floor, the turning radius of the arch rail is from the turning center to the tip of the hollow arch rail, and compared with the case where the arch rail is extended to the floor surface. Since the diameter can be made smaller, the installation space can be made much smaller.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The apparatus of the present invention will be described below along the embodiments shown in the drawings. FIG. 1 is a diagram showing the overall configuration of the present invention.
[0009]
In FIG. 1, an interior material 2 is provided in a building structure 1. A test chamber 4 is defined by the interior material 2 and the floor 3. The passenger car 5 is taken in and out of the test chamber 4 through the opening 6 of the interior material 2. The opening 6 is provided with a door 7. A bell mouth 8 is provided in front of the door 7 and in front of the passenger car 5 for blowing wind, snow, or haze in order to test the passenger car 5. A turntable 9 is provided on the upper interior material 2, that is, on the ceiling of the test chamber 4. An arcuate arch rail 10 is suspended below the turntable 9, and the arch rail 10 can be rotated 360 degrees by rotating the turntable. That is, since the motor 13 is provided on the upper part of the arch rail 10 and its shaft is coupled to the turning wheel 12, the turntable 9 is rotated through the turning wheel 12 by driving the motor 13, and the arch rail 10 is Rotate as shown by arrow A.
[0010]
A bank frame 11 is suspended from the arch rail 10 by a suspension member having a moving mechanism. The bank frame 11 is provided with a light irradiation main bank 14 to which a heat radiation bulb 15 and a reflecting mirror 16 are attached. As will be described later, the bank frame 11 moves on the arch rail 10. The bank frame 11 and the light irradiation main bank 14 are suspended from the arch rail 10 while being shifted (eccentric) from the center point of support. This is to enable solar radiation in the center of the sky when positioned at one end of the arch rail and in the state corresponding to the horizon (horizon) when positioned at the other end, and to reduce the radius of rotation of the arch rail as much as possible. It is.
[0011]
Further, in this embodiment, the arch rail 10 is supported so as to be biased toward the one end side (decentered) as a semicircular arc shape as shown in the figure. The reason for this is that when the light irradiation main bank 14 is located in the center of the sky, the arch rail position where the light irradiation main bank 14 is substantially parallel to the floor surface is one end side, and the light irradiation main bank 14 is the horizontal line on the other end side. It is designed to be close to the (horizon) state. Thereby, it becomes possible to simulate solar radiation in all directions by rotating the support position on the ceiling side. Further, the heat radiation bulbs 15 provided in the light irradiation main bank 14 are shown in only one row in the drawing, but are arranged in a plurality of planes on a rectangular plane. In addition, this heat-dissipating light bulb has an arrangement in which the corners of the bank are reduced in order to make the turning radius as small as possible (since the turning radius is affected by the diagonal size of the bank).
[0012]
In the present apparatus, an auxiliary bank 22 is provided. This auxiliary bank moves on a straight rail attached to a position higher than the arch rail so that it can move to the ceiling of the test room 4 without hitting the arch rail 10 attached to the turntable 9. The auxiliary bank moving means can drive the motor 21 provided on the traveling body side to rotate the roller, thereby making the auxiliary bank 22 close to or away from the light irradiation main bank 14 side. The auxiliary bank also has a plurality of heat radiation bulbs arranged in a plane. The auxiliary bank is also attached eccentrically to the arch rail 10 side with respect to the center of the support portion of the linear rail.
[0013]
By providing the auxiliary bank 22 as described above, the auxiliary bank 22 is arranged in the light irradiation main bank 14 and irradiated with light so that the light amount and light intensity of the light irradiation main bank 14 are not insufficient. (When the sun is located at the center of the sky, the maximum solar radiation state is obtained, but this state can be simulated). In addition, by providing the auxiliary bank 22, it is not necessary to increase the size of the light irradiation main bank 14 provided on the arch rail side, so that not only the turning radius is reduced, but also the power consumption required for driving the device itself is reduced. It becomes possible to reduce.
[0014]
FIG. 2 is a diagram showing a wiring system of the movable light irradiation device.
In FIG. 2, the light irradiation main bank 14 has a large number of heat radiation bulbs 15 and their reflecting mirrors 16 arranged in a plane on the passenger car 5 side. Electric power is supplied to the heat-dissipating light bulb 15 by cables 32 and 33 from a control panel (not shown) via relay boxes 23 to 29 and cable carriers 30 and 31. As described above, by providing the cable carriers 30 and 31, the cable is prevented from being entangled even if the light irradiation main bank 14 moves along the arch rail 10. The cable carriers 30 and 31 may be of a curtain rail type. The plurality of heat-dissipating bulbs 15 provided in each bank can be selected and controlled to blink by a switch on a control panel (not shown). By controlling the heat-dissipating bulb 15 to blink, the amount of light and the light intensity to the irradiation object can be controlled.
[0015]
Note that a twist-resistant cable is used as the cable so that the cable is not twisted by the turntable 9 or the like to cause disconnection or the like.
[0016]
FIG. 3 is a diagram for explaining the inclination driving of the light irradiation main bank.
In FIG. 3, the bank frame 11 includes a motor 17, a speed reducer 18, and a sprocket 19 on the rear side of the light irradiation main bank 14. When the motor 17 is driven, the sprocket 19 is rotated via the speed reducer 18, and the sprocket 19 moves while meshing with the chain 20, whereby the light irradiation main bank 14 moves and tilts as indicated by an arrow B. The chain 20 may be various flexible bodies such as a belt and a rope. By driving the motor 17, the light irradiation main bank 14 is tilted in the direction of arrow B through the bank frame 11, so that the elevation angle (tilt angle) of the light irradiation main bank 14 viewed from the passenger car 5 that is the light irradiation object. Can be changed and adjusted arbitrarily.
[0017]
In the embodiment shown in FIG. 1, by the movement of arrows A and B, the light irradiation main bank 14 can simulate an arbitrary operation trajectory for each season of the sun, and reproduces the in-vehicle environment caused by the movement of the sun. Thus, it is possible to carry out various tests for an arbitrary steering angle when viewed from the passenger car 5.
[0018]
These movements can be arbitrarily set according to the rotation speed, rotation direction, and rotation timing of each motor 13, 17, and can be easily implemented by a programmable controller (not shown). Since power is supplied to the heat-dissipating bulb 15 by a twist-proof cable 34, it is preferable to install a stopper or the like that can prevent turning by one rotation at a time, paying attention to the continuous rotation in the same direction as indicated by the arrow A.
[0019]
In FIG. 4, when the light irradiation main bank 14 turns in the direction A, an auxiliary bank 22 provided alongside the light irradiation main bank 14 that secures an irradiation amount in the sky is attached to the apparatus. By retracting the main bank 14 in the horizontal C direction, the turning radius of the light irradiation main bank 14 (the turning radius of the arch rail 10) can be reduced.
[0020]
The present invention is not limited to the above embodiment, and can be implemented in the following various aspects.
[0021]
FIG. 5 is a view for explaining the vertically movable state of the light irradiation main bank as another embodiment of the present invention. This embodiment is obtained by adding an upward / downward movement of an arrow D to the embodiment of FIG. That is, a motor 35 and a screw jack 36 are added on the bank frame 11 to move the light irradiation main bank up and down. In this configuration, by controlling the drive of the motor 35, the distance between the passenger car 5 and the light irradiation main bank 14 can be changed without changing the elevation angle of the light irradiation main bank 14 as viewed from the passenger car 5. For this reason, in addition to blinking of the heat-dissipating light bulb 15, the light amount and light intensity with respect to the passenger car 5 can be freely adjusted by adjusting this distance. In place of the screw jack 36, a ball screw or the like may be used.
[0022]
Further, by adjusting the driving of the motors 13 and 17, the light irradiation main bank 14 can be moved not only in front of the passenger car 5 but also to the left and right lateral sides, the rear position and all the upper positions. Light can be irradiated from the direction. As described above, by moving the single light irradiation main bank 14, the passenger car 5 can be fixed, and light can be irradiated from all directions except under the passenger car 5.
[0023]
FIG. 6 shows still another embodiment of the present invention.
In FIG. 6, the second arch rail 40 having a semicircular arc is provided at the lower part of the turntable 9 for rotation, and the first arch rail 10 is further suspended below the second arch rail 10 similarly to the embodiment of FIG. A light irradiation main bank 14 is suspended from the first arch rail 10 as in FIG. As shown in the figure, a motor 37, a speed reducer 38, a sprocket 39, and a chain 40 are provided so that the first arch rail 10 can move in the direction of arrow E on the second arch rail 40. When the motor 37 is driven, the sprocket 39 is rotated through the speed reducer 38, whereby the light irradiation main bank 14 is added with the right and left slanted movement of the arrow E. With this configuration, the movement of the sun is more accurately detected. Can be simulated. The chain 40 may be a gear-shaped protrusion or various flexible bodies such as a belt and a rope.
[0024]
FIG. 7 shows still another embodiment of the present invention.
In the present embodiment, a linear rail is attached to the ceiling of the test chamber 4 so that the light irradiation main bank 14 moves linearly, and a suspension member provided with a motor 41 is provided on the linear rail, and FIG. The one with the structure is attached as it is. That is, a drive mechanism for moving the arch rail 10, the bank frame 11, and the light irradiation main bank 14 is provided below the turn table 9, and includes a turntable 9, a turning wheel 12, and a motor 13, and a mounting member for the drive mechanism. The light irradiation main bank 14 is attached. That is, the drive mechanism attachment member has a turntable structure. As a result, the light irradiation main bank 14 can be moved laterally (moved in the direction of arrow F in the figure). Thereby, even if the size of the irradiated object changes, it can cope with it.
[0025]
In all of the above embodiments, various discharge tubes such as a fluorescent tube, a neon tube, and a sodium tube may be optionally provided in place of the light-emitting bulb 15 of the light irradiation main bank or the auxiliary bank.
[0026]
