Reference examples and examples of the present invention will be described below with reference to the drawings.
[Reference example 1]

1 and 2 are a side view and a plan view showing a boarding compartment of a mechanical parking system according to one reference example of the present invention.

An openable/closable electric door 3 is attached to a doorway 2 of a boarding room 1, and a parked vehicle 4 boarded from the doorway 2 with the electric door 3 open is prepared in the boarding room 1.例文帳に追加It is stopped at a predetermined position on the tray 5. At this time, the driver of the parked vehicle 4 drives the parked vehicle 4 onto the tray 5 while being assisted by the mirror 6 and the vehicle guidance indicator light 7 arranged directly in front of the tray 5, and the driver of the parked vehicle 4 drives the parked vehicle 4 onto the tray 5. The tire position is regulated by the wheel stop 8 which is provided so that the vehicle is stopped at the stop position.

In addition, in order to detect that the front tire 4A of the parked vehicle 4 is securely positioned on the car stop 8, a beam type illumination section 9A and a light receiving section 9B are dispersed at low positions on the side wall of the passenger compartment 1. A tire position detection device 9 is arranged in such a manner that the In this tire position detection device 9, when the tire 4A is at the stop position by the car stop 8, the tire position detection beam 10 emitted from the illumination part 9A and received by the light receiving part 9B is blocked by the tire 4A of the parked vehicle 4. Occasionally, it is detected that the tire 4A is in a parked position on the bollard 8. In this reference example, the illumination section 9A and the light receiving section 9B are arranged so that the tire position detection beam 10 passes through substantially the center position of the car stop 8 in the approach direction of the parked vehicle 4 .

Between the side walls of the passenger compartment 1, a front side protrusion detector 11 for detecting protrusion of the front side of the parked vehicle 4 from the tray 5 and a rear side of the parked vehicle 4 with respect to the tray 5 are provided. A rear side protrusion detector 12 is configured to detect protrusion of the rear side.

The front-side protrusion detector 11 is arranged on both side walls of the passenger compartment 1, and has a beam-type illumination unit 11A and a light-receiving unit 11B at a height position for detecting protrusion at the front-side vehicle end of the parked vehicle 4. Distributed and arranged. Therefore, when the protrusion detection beam 13 between the illumination section 11A and the light receiving section 11B is blocked by the vehicle body end portion of the parked vehicle 4, it is detected that the front side of the parked vehicle 4 protrudes from the predetermined position. .

The rear-side protrusion detector 12 is arranged on both side walls of the passenger compartment 1, and has a beam-type illumination unit 12A and a light-receiving unit 12B at a height position for detecting protrusion at the rear-side vehicle end of the parked vehicle 4. are distributed and arranged. Therefore, when the protrusion detection beam 14 between the illumination section 12A and the light receiving section 12B is blocked by the vehicle body end of the parked vehicle 4, it is detected that the rear side of the parked vehicle 4 protrudes from the predetermined position to the rear side. ing.

According to the mechanical parking device having such a configuration, when the front tire 4A of the parked vehicle 4 is correctly positioned at the stop position by the wheel stopper 8, the distance from the wall surface to the front end of the parked vehicle is increased as in the conventional art. Since the beam-type tire position detection device 9, which has a proven track record and is highly reliable, is used instead of using a distance measuring means that is less reliable, the tire 4A positioned at the correct stop position is irradiated from the illumination unit 9A. It is possible to accurately and reliably detect that the tire position detection beam 10 received by the light receiving portion 9B is blocked by the tire 4A. In other words, detection can be performed with good precision with a simple configuration.

Moreover, even if the parked vehicles have various vehicle lengths, the front protrusion detection beam 13 between the illuminating section 11A and the light receiving section 11B is detected when the parked vehicle is stopped at the correct stop position. is not blocked by the vehicle body end of the parked vehicle 4, it is detected that the front side of the parked vehicle 4 does not protrude from the predetermined position.

Similarly, even if the parked vehicles have various vehicle lengths, the rear protrusion detector 12 detects the protrusion detection beam between the illuminating section 12A and the light receiving section 12B when the parked vehicle is stopped at the correct stop position. 14 is not blocked by the vehicle body end of the parked vehicle 4, it is detected that the rear side of the parked vehicle 4 does not protrude beyond the predetermined position.

FIG. 3 is a plan view showing a boarding compartment of a mechanical parking system according to another embodiment of the present invention.

The tire position detection device 9 in this reference example has a horizontal plane beam illumination unit 16A that irradiates a plurality of tire position detection beams 15A to 15F on the same horizontal plane to one of the side walls in the passenger compartment 1 when viewed from the parked vehicle 4. and a horizontal beam receiving portion 16B disposed on the other side wall of the passenger compartment 1 so as to face the horizontal beam irradiating portion 16A.

The substantially parallel tire position detection beams 15A to 15F of the tire position detection device 9 are arranged in the same horizontal plane and pass inside the both ends of the car stop 8 in the approach direction of the parked vehicle 4. It is configured to detect stopping inside the Since other configurations are the same as those of the previous reference example, the same reference numerals are given to equivalent parts, and detailed description thereof will be omitted.

In this way, a horizontal plane beam illuminator 16A that irradiates a plurality of tire position detection beams 15A to 15F on the same horizontal plane, and a horizontal plane beam receiver that receives each of the tire position detection beams 15A to 15F from the horizontal plane beam illuminator 16A. By using the tire position detection device 9 having 16B, the position detection range of the tire 4A in the traveling direction of the parked vehicle can be further expanded compared to the previous embodiment. Accordingly, even if the car stop 8 is configured to have a width that allows the tires 4A to be stopped slightly back and forth in the entering direction of the parked vehicle 4, the tire positions can be accurately detected.

Moreover, even if the parked vehicles have various vehicle lengths, the front side protrusion detector 11 can detect protrusion between the illumination section 11A and the light receiving section 11B in a state where the parked vehicle 4 is stopped at a predetermined stop position. When it is detected that the beam 13 is blocked by the end of the vehicle body of the parked vehicle 4, or when the rear protrusion detector 12 detects the protrusion detection beam 14 between the illumination unit 12A and the light receiving unit 12B, the end of the vehicle body of the parked vehicle 4 is detected. is blocked, the front and rear stop positions of the parked vehicle 4 in the traveling direction can be easily adjusted by using the width of the car stop 8 in the entering direction of the parked vehicle 4.例文帳に追加

Further, as described above, the substantially parallel tire position detection beams 15A to 15F of the tire position detection device 9 are arranged in the same horizontal plane so as to pass inside the both ends of the stop 8 in the approach direction of the parked vehicle 4. stop inside the wheel stop 8.

Since the positional relationship between both ends of the car stop 8 in the approach direction of the parked vehicle 4 and the tire 4A of the parked vehicle 4 at the normal stop position is determined in this way, the function of the car stop 8 in the same approach direction is utilized. The tire 4A of the parked vehicle 4 can be appropriately managed by the tire position detection device 9.
[Example]

FIG. 4 is a plan view showing a boarding compartment of the mechanical parking system according to the embodiment of the present invention .

The tire position detection device 9 in this embodiment includes a horizontal beam illumination unit 16A that irradiates three tire position detection beams 15A to 15C on the same horizontal plane, and a horizontal beam light receiving unit arranged opposite the horizontal beam illumination unit 16A. 16B.

In the horizontal plane beam illumination section 16A shown in FIG. 3, all of the multiple tire position detection beams 15A to 15F on the same horizontal plane are parallel lights. The tire position detection beams 15A and 15C positioned on the sides are parallel beams on the same horizontal plane, while the tire position detection beam 15B positioned in the center does not interfere with the adjacent tire position detection beams 15A and 15C. , and obliquely irradiated on the same horizontal plane.

Also in this embodiment, the tire position detection beams 15A and 15C of the tire position detection device 9, which are on the same horizontal plane and are substantially parallel, pass inside the both ends of the stop 8 in the approach direction of the parked vehicle 4. 4 tires 4A stop inside the wheel stop 8 is detected. Since other configurations are the same as those of the previous embodiment, the same reference numerals are given to equivalent parts and detailed description thereof is omitted.

According to such a configuration, one tire position detection beam 15B that is irradiated obliquely is used between the tire position detection beams 15A and 15C on both sides. The number can be reduced, and the tire position detection device 9 can be made inexpensive.

Moreover, even if the number of tire position detection beams is reduced, the tire position detection beam 15B located in the center is oblique on the same horizontal plane. By enlarging it, the position of the tire 4 can be accurately detected.

Even if the width of the car stop 8 in the entering direction of the parked vehicle 4 is, for example, about 600 mm, the tire position detection beams 15A and 15C positioned on both sides of the plurality of tire position detection beams irradiated on the same horizontal plane are parallel beams. Therefore, the tire position detection device 9 can relatively easily change or increase the width interval of the parallel light, and can further expand the position detection range of the tire 4A. Further, even if the stop range is expanded by widening the car stop 8 in the approach direction of the parked vehicle 4, the stop position of the tire 4A within the stop range will be detected by one tire position detection beam 15B obliquely irradiated on the same horizontal plane. can be effectively used to accurately detect.

Since other configurations are the same as those of the previous reference example and the embodiment, the same reference numerals are given to equivalent parts and detailed description thereof will be omitted.

Using a plurality of pairs of illuminating parts 9A, 9C and light receiving parts 9B, 9D in this way makes it possible to form a wider width in the approach direction of the parked vehicle 4, so that the position detection range of the tire 4A in the same approach direction can be expanded. Can be extended. Moreover, even if the tires 4A of the parked vehicle 4 are stopped in the car stop 8 slightly back and forth in the approach direction, the tire positions can be detected more accurately.

In addition, since the car stop 8 can form a wider width in the approach direction of the parked vehicle 4, even if the parked vehicles have various vehicle lengths, the parked vehicle 4 can be parked at a predetermined stop position. , when the front protrusion detector 11 detects that the protrusion detection beam 13 between the illuminating part 11A and the light receiving part 11B is blocked by the end of the vehicle body of the parked vehicle 4, or when the rear protrusion detector 12 detects the illumination When it is detected that the end portion of the vehicle body of the parked vehicle 4 blocks the protrusion detection beam 14 between the portion 12A and the light receiving portion 12B, the width of the parking stop 8 in the approach direction of the parked vehicle 4 is used to detect the position of the parked vehicle 4. The front and rear stop positions in the traveling direction can be easily adjusted.

In each reference example and embodiment described above, the tire position detection device 9, the front-side protrusion detector 11, and the rear-side protrusion detector 12 are installed on the side wall of the passenger compartment 1, respectively. The same effect can be obtained even if the driver of the parked vehicle 4 or the like is installed at another position where there is no hindrance to movement in the passenger compartment 1. - 特許庁
