It is the side view to which the tray side charge plug holding part which is the principal part of the tray apparatus for mechanical parking apparatuses shown in FIG. 2 was expanded. FIG. 5 is a front view of the tray-side charging plug holder shown in FIG. 4.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  2 and 3 are a front view and a plan view showing a tray device for a mechanical parking device according to an embodiment of the present invention, which are configured for mounting on an electric vehicle. The base 1 is mainly configured, and a plurality of wheels 2 running on a rail (not shown) are rotatably supported on the lower surface of the base 1, while an electric vehicle enters the upper surface of the base 1. In order to reliably guide the tire 3 to the tire mounting portions 4A and 4B, there are center-side standing portions 5A and 5B and outer standing portions 6A and 6B protruding upward. The tire mounting portions 4A and 4B formed between the central standing portions 5A and 5B and the outer standing portions 6A and 6B are provided with position restricting portions 7A and 7B for restricting the stopping position of the tire of the electric vehicle that has entered. Yes.

  The outer upright portions 6A and 6B are portions located on the side of the electric vehicle in which they are mounted, and have relatively narrow attachment portions 8A and 8B formed on the upper surface thereof, and one end of the attachment portion 8A. In the vicinity, as shown in FIG. 3, a tray-side charging plug storage unit 9 and a power cable lead-out unit 10 are configured. Further, in the space formed in the lower portion of the attachment portion 8A, a rotatable pulley 11 and a movable drum 12 arranged so as to be movable up to the moving terminal portion 12A on the pulley 11 side, in the electric vehicle entry direction, A ratchet winder 13 that pulls the movable drum 12 back to the steady position shown in the figure is arranged.

  FIG. 1 is a side view of the outer standing portion 6A. The power cable lead-out part 10 attached to the attachment part 8A smoothly moves when a power cable 25 described later is pulled out from the lower part of the attachment part 8A or returned to the lower part of the attachment part 8A. It is a guide. The pulley 11 disposed at the lower portion of the power cable lead-out portion 10 is configured to be rotatable by a rotation shaft 14 at the center, and in order to smoothly move the pulley 11 while changing the extended direction of the power cable 25 described later. It is intended to rotate.

  In the vicinity of the opposite end of the attachment portion 8A, a movable drum 12 is disposed that can smoothly move the remaining space formed in the lower portion of the attachment portion 8A in the longitudinal direction of the outer upright portion 6A. In order to smoothly move the movable drum 12 in the same direction, a guide mechanism is configured, and the guide mechanism can take various configurations. Here, the center of the movable drum 12 is rotatable. , A substantially horizontal guide surface 16 that guides the rotary shaft 15 in the longitudinal direction of the outer upright portion 6A, and a guide in the longitudinal direction of the outer upright portion 6A while rotating the outer peripheral portion of the movable drum 12. The other guide surface 23 formed almost horizontally, the lever 17 having one end rotatably connected to the rotary shaft 15, and mounted so as to move while rotating on the guide surface 23 in the vicinity of the other end of the lever 17. A guide roller 18 is provided.

  The ratchet winder 13 disposed at the opposite end of the mounting portion 8A includes a winding portion 19 having a rotatable rotating shaft 20 at the center, and an end portion wound around the winding portion 19. And a wire 21 connected to the other end of the lever 17 of the movable drum 12 described above. When the wire 21 is pulled out, the return force of the return means (not shown) is accumulated, and the wire by the return means is stored. The unwinding of 21 is prevented by a ratchet. However, when the wire 21 is released in a state in which the wire 21 is slightly pulled out to release the ratchet, the wire 21 is rewound onto the winding portion 19 by the stored restoring force. A guide roller 22 and the like are disposed at a wire drawing portion in the ratchet winder 13.

  The return means in the ratchet type winder 13 here can not only simply rewind the wire 21 but also the movable drum 12 and the power cable 25 connected to the wire 21 can be pulled back to the steady position.

  The tray-side charging plug storage portion 9 disposed near the other end of the mounting portion 8A stores the charging plug 26 to be connected when charging the battery in a steady state in a power supply terminal attached to the electric vehicle side. The protective cover 28 is attached to the base 27 fixed to the upper surface of the attachment portion 8A so as to be openable and closable. By holding the charging plug 26 in the protective cover 28, the mechanical parking device has The rainwater brought in by the parked vehicle is prevented from dripping onto the electrical contact portion and adversely affecting the electrical insulation.

  The above-described charging plug 26 is connected to an end portion 25B of the power cable 25 led out from the power cable lead-out portion 10. On the other hand, the power cable 25 introduced into the lower portion of the attachment portion 8A by the power cable lead-out portion 10 is turned around the pulley 11 that moves smoothly by its rotation, and the direction is reversed after being hooked on the movable drum 12. Thus, a reciprocating path section arranged vertically is formed, and the vicinity of the power cable lead-out section 10 in the return path is mechanically held by the power cable fixing section 24. The power cable fixing portion 24 is not an electrical connection portion, and prevents the power cable 25 from moving at the same portion.

  The end portion 25A of the power cable 25 is further guided using the lower portion of the base 1 and the inner space portions of the central upright portions 5A and 5B and the outer upright portions 6A and 6B, and is connected to the tray side contactor 35. . This tray side contact 35 is attached at a position where it comes into electrical contact with a fixed side contact provided on the floor side of the storage position when the tray device shown in FIGS. 1 to 3 is stored in a predetermined storage position. It has been. The stationary contact is electrically connected to the power supply, and the charging plug 26 is connected to the power supply by contact between the stationary contact and the tray contact 35.

  Here, the above-described tray-side charging plug storage unit 9 will be further described with reference to FIGS. A protective cover 28 is attached to the base 27 of the tray-side charging plug storage 9 using a hinge 29 so as to be opened and closed. The protective cover 28 may be made of a transparent plastic or may be opaque, and may be emphasized by a charging plug mark or character display which is easy to understand for the user. The protective cover 28 on the opposite side of the hinge 29 has a protective cover 28 so that the protective cover 28 can be opened and closed even if the grip 30 used for opening and closing and the power cable 25 for storing the charging plug 26 are provided. And a cutout portion 31 in which a part of the cutout portion 31 is cut out. Further, one end of a mounting member 32 which is shaped like a spring so as to have a spring action is fixed to the base 27 in the protective cover 28, and a storage portion 33 is attached to the other end of the mounting member 32. The storage portion 33 forms an insertion port facing obliquely upward so that the charging plug 26 extended from the electric vehicle side can be inserted from the oblique upper portion.

  The storage portion 33 having such a configuration with the insertion port facing upward can easily perform the storage operation of the charging plug 26 using the spring action of the mounting member 32, but the insertion port is directed upward. Therefore, it is easy for raindrops and dust to adhere to the electrical connection portion, which may cause electrical contact troubles. However, since the tray-side charging plug storage unit 9 includes the protective cover 28 that covers the storage unit 33 so as to be openable and closable, raindrops and dust are not formed in the electrical connection portion even when the insertion port faces upward. Will not stick and will not cause electrical contact troubles.

  The storage portion 33 disposed in the tray-side charging plug storage portion 9 has a structure with an upward insertion port, and is inserted into the storage portion 33 with the charging plug 26 at the tip of the charging cable 25 facing downward. Therefore, the charging plug 26 is inserted downward, and can be easily inserted while visually confirming the insertion state and the like. Moreover, since the storage portion 33 arranged in the tray-side charging plug storage portion 9 is swingably supported using the attachment member 32 having a spring action, the spring action of the attachment member 32 is used. Therefore, the storing operation can be performed without applying excessive force.

  Further, the protective cover 14 of the tray-side charging plug connecting portion 9 is opened and closed substantially on the projection surface of the attachment portion 8A so as not to protrude to the side portion of the attachment portion 8A in the opened state. In other words, the tray-side charging plug storage portion 9 mounted on the outer upright portion 6A formed parallel to the intrusion direction of the parked vehicle has the protective cover 28 that opens and closes in a direction parallel to the intrusion direction of the parked vehicle. .

  In order to stop the parked vehicle at a predetermined position on the base 1 in this way, the outer standing portion 6A is located on the side of the parked vehicle mounted on the tray device and continuously formed in the intrusion direction of the parked vehicle. , 6B, there is a space that is not used much above and below, but a narrow mounting portion 8 is formed above the outer standing portion 6A, and an upper portion of the mounting portion 8 is formed. The tray side charging plug holding portion 9 is effectively utilized by arranging the charging side.

  On the other hand, when the mounting portion 8A formed on the upper side of the outer upright portion 6A is used to arrange the tray-side charging plug storage portion 9, a residual space is formed at the lower portion. The pulley 11, the movable drum 12, the ratchet winder 13, and the power cable fixing part 24 described in (1) are actively utilized by arranging them in a substantially horizontal direction.

  Next, the case where the battery of the electric vehicle mounted on the tray device is charged during parking will be described.

  In the mechanical parking device, all the tray devices may be configured for charging an electric vehicle as shown in FIGS. 1 to 3, or a plurality of some of the entire devices may be configured for charging an electric vehicle. Also good. In the latter case, a staff member or a driver of a parked vehicle calls the tray device for charging the electric vehicle by selecting the use of charging the battery while operating the operation button or the like and parking. In any case, first, the electric vehicle which is a parked vehicle is stopped at a predetermined position of the base 1 constituting the tray device.

  Thereafter, the protective cover 28 is opened using the grip portion 30 of the tray-side charging plug housing portion 9, the charging plug 26 is taken out, and connected to the battery power supply terminal on the electric vehicle side. At this time, since the protective cover 28 is configured to open in a direction parallel to the direction in which the electric vehicle enters, the protective cover 28 does not come into contact with the electric vehicle when the protective cover 28 is opened, and the degree of opening is not hindered by surrounding structures. In addition, since this connection work is before the tray device is guided and housed in the storage position, the charging plug 26 and the power cable 25 are not yet connected to the power source, so anyone can safely perform the connection work.

  When the connection between the charging plug 26 and the battery power supply terminal on the electric vehicle side is completed, the protective cover 14 is closed using the grip portion 30. Therefore, even if the battery is charged while the electric vehicle is parked for a long time, raindrops do not enter the storage portion 33 and dust does not collect.

  Thereafter, when the tray device shown in FIGS. 1 to 3 is stored in a predetermined storage position of the mechanical parking device, a fixed contact provided on the floor surface side of the storage position and a tray side provided on the lower portion of the base 1 The contact 35 is in electrical contact, the charging plug 26 is connected to the power source, and charging of the battery is started.

By the way, to charge the battery of the electric car mounted on the tray device while parking,
When the charging plug 26 is taken out from the tray-side charging plug housing portion 9 and connected to the battery power supply terminal on the electric vehicle side, the position of the battery power supply terminal on the electric vehicle side varies depending on the vehicle type, and the charging plug 26 is connected. It may be necessary to pull out the extended power cable 25 and extend it. Next, the operation at this time will be described.

  First, after the charging plug 26 is taken out from the tray-side charging plug housing portion 9, the charging plug 26 side is further pulled up in order to pull out the power cable 25 from the lower portion of the attachment portion 8A. Then, the power cable 25 moves the movable drum 12 toward the pulley 11 while rotating the pulley 11, and the length of the reciprocating path portion is reduced. The movable drum 12 moves smoothly while the rotation shaft 15 rotates along the guide surface 16 and the roller 18 rotates along the guide surface 23.

  At this time, the wire 21 of the ratchet winder 13 connected to the movable drum 12 via the lever 17 is also pulled out, and at the same time, the return force for pulling the wire 21 is stored while the wire 21 is prevented from being pulled back by the ratchet. Is done.

  The movable drum 12 can move up to a terminal end portion 12A indicated by a dotted line in FIG. When the longitudinal dimension of the base 1 in the tray device is 5500 mm, for example, and the dimension between the rotating shaft 15 of the movable drum 12 at the stationary position and the rotating shaft 15 in the terminal end portion 12A is 3000 mm, the power cable 25 reciprocates in the same portion. Since the road portion is formed, it can be stretched by about 6 m at the maximum. This is long enough to connect the charging plug 26 to the battery power supply terminal even if the battery power supply terminal of the electric vehicle is configured at various positions. This maximum drawing dimension of about 6 m can be obtained by arranging the ratchet winder 13 and the tray-side charging plug storage unit 9 in the vicinity of both ends in the longitudinal direction of the mounting part 8A. If so, the longitudinal dimension of the base 1, the position of the ratchet winder 13 and the tray-side charging plug storage unit 9, the position of the terminal end 12 </ b> A of the movable drum 12, etc. can be changed as appropriate.

  When the charging plug 26 provided at the end portion 25B of the power cable 25 is pulled, the movable drum 12 moves, and at the same time, a force in the same direction is applied to the power cable 25 as a whole. Since the cable 25 is held, it is received by an insulation coating or the like, and does not adversely affect the electrical connection.

  After the battery is charged, the charging plug 26 is removed from the power supply terminal of the electric vehicle, and this time, when the power cable 25 is returned to the lower part of the attachment portion 8A, the power cable 25 is pulled slightly to pull the ratchet winder 13 ratchet. This is done by removing the power cable 25 in this state. Then, the wire 21 is wound around the winding portion 19 by the stored return means, and at the same time, the movable drum 12 is driven to the original position. When the movable drum 12 is returned to the steady position indicated by the solid line, the power cable 25 is also in the original state shown in FIG. In this state, when the charging plug 26 is held at a predetermined position inside the tray-side charging plug housing portion 9, a steady state is obtained.

  In this manner, in a vehicle type in which the battery power supply terminal is located in the vicinity of the tray-side charging plug housing portion 9 with the electric vehicle mounted on the tray device, the charging taken out from the tray-side charging plug housing portion 9 is performed. Charging can be performed by connecting the plug 26 to the battery power supply terminal. However, in a vehicle type in which an electric vehicle is mounted on the tray device and the battery power supply terminal is located at a position away from the tray-side charging plug storage unit 9, the charging for taking out from the tray-side charging plug storage unit 9 is performed. After the power cable 25 has an arbitrary length by pulling the plug 26, the charging plug 26 can be connected to the battery power supply terminal for charging.

  According to the mechanical parking device tray device described above, the length of the power cable 25 is adjusted using the remaining space at the lower portion of the outer upright portion 6A formed in parallel with the intrusion direction of the electric vehicle. Since it is performed by the movable drum 12 that moves in the parallel direction, it can easily cope with the position of the battery power supply terminal on the electric vehicle side with a simple configuration, and the height and width of the mounting portion 8A are suppressed. However, the moving distance of the movable drum 12, that is, the adjustment length of the power cable 25 can be increased. Although it is conceivable to wind up the entire power cable 25 as the movable drum 12 is fixed and extended, in this case, the diameter of the drum is increased and the height of the mounting portion 8A is increased. Will also increase the width of the mounting portion 8A.

  In addition, since the length of the power cable 25 is adjusted by moving the movable drum 12, most of the power cable 25 is neatly stored under the mounting portion 8A in a steady state, and the power cable 25 is stretched. After that, since the movable drum 12 can be moved and stored, it can be similarly returned to a clean state. Furthermore, since the power cable 25 is inserted and removed by the movement of the movable drum 12, the power cable 25 can be arranged in an orderly manner at the lower portion of the attachment portion 8A.

  Further, since the power cable 25 arranged using the lower portion of the attachment portion 8A is pulled out to the upper portion after being hung on the pulley 11 arranged in the vicinity of the lead-out portion of the lower portion of the attachment portion 8A, a comparison of the lower portion of the attachment portion 8A is made. The power cable 25 can be smoothly inserted and removed even when the movable drum 12 that moves in the horizontal direction is used, using a relatively narrow residual space.

  Further, an outer upright portion 6A is formed on the side portion of the base 1 in parallel with the intrusion direction of the electric vehicle, and a tray side charging plug storage portion 9 is mounted on the outer upright portion 6A. By providing the protective cover 28 that opens and closes in the direction parallel to the intrusion direction of the electric vehicle in the portion 9, there is no contact with the parked vehicle when the protective cover 28 is opened, and the degree of opening is not hindered by surrounding structures. The charging plug 26 can be protected from raindrops, dust and the like while the tray side charging plug housing 9 is made thin to prevent the tray apparatus from becoming large, and the reliability can be further enhanced.
